• Windows Azure Myths

  - by BuckWoody

  Windows Azure is part of the Microsoft "stack" - the suite of software and services we offer. Because we have so many products in almost every part of technology, it's hard to know everything about all parts of what we do - even for those of us who work here. So it's no surprise that some folks are not as familiar with Windows and SQL Azure as they are, say Windows Server or XBox. As I chat with folks about a solution for a business or organization need, I put Windows Azure into the mix. I always start off with "What do you already know about Windows Azure?" so that I don't bore folks with information they already have. I some cases they've checked out the product ahead of time and have specific questions, in others they aren't as familiar, and in still others there is a fair amount of mis-information. Sometimes that's because of a marketing failure, sometimes it's hearsay, and somtetimes it's active misinformation. I thought I might lay out a few of these misconceptions. As always - do your fact-checking! Never take anyone's word alone (including mine) as gospel. Make sure you educate yourself on your options. Your company or your clients depend on you to have the right information on IT, so make sure you live up to that. Myth 1: Nobody uses Windows Azure It's true that we don't give out numbers on the amount of clients on Windows and SQL Azure. But lots of folks are here - companies you may have heard of like Boeing, NASA, Fujitsu, The City of London, Nuedesic, and many others. I deal with firms small and large that use Windows Azure for mission-critical applications, sometimes totally on Windows and/or SQL Azure, sometimes in conjunction with an on-premises system, sometimes for only a specific component in Windows Azure like storage. The interesting thing is that many sites you visit have a Windows Azure component, or are running on Windows Azure. They just don't announce it. Just like the other cloud providers, the companies have asked to be completely branded themselves - they don't want you to be aware or care that they are on Windows Azure. Sometimes that's for security, other times it's for different reasons. It's just like the web sites you visit. For the most part, they don't advertise which OS or Web Server they use. It really just shouldn't matter. The point is that they just use what works to solve a given problem. Check out a few public case studies here: https://www.windowsazure.com/en-us/home/case-studies/ Myth 2: It's only for Microsoft stuff - can't use Open Source This is the one I face the most, and am the most dismayed by. We work just fine with many open source products, including Java, NodeJS, PHP, Ruby, Python, Hadoop, and many other languages and applications. You can quickly deploy a Wordpress, Umbraco and other "kits". We have software development kits (SDK's) for iPhones, iPads, Android, Windows phones and more. We have an SDK to work with FaceBook and other social networks. In short, we play well with others. More on the languages and runtimes we support here: https://www.windowsazure.com/en-us/develop/overview/ More on the SDK's here: http://www.wadewegner.com/2011/05/windows-azure-toolkit-for-ios/, http://www.wadewegner.com/2011/08/windows-azure-toolkits-for-devices-now-with-android/, http://azuretoolkit.codeplex.com/ Myth 3: Microsoft expects me to switch everything to "the cloud" No, we don't. That would be disasterous, unless the only things you run in your company uses works perfectly in Azure. Use Windows Azure  - or any cloud for that matter - where it works. Whenever I talk to companies, I focus on two things: Something that is broken and needs to be re-architected Something you want to do that is new If something is broken, and you need new tools to scale, extend, add capacity dynamically and so on, then you can consider using Windows or SQL Azure. It can help solve problems that you have, or it may include a component you don't want to write or architect yourself. Sometimes you want to do something new, like extend your company's offerings to mobile phones, to the web, or to a social network. More info on where it works here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx Myth 4: I have to write code to use Windows and SQL Azure If Windows Azure is a PaaS - a Platform as a Service - then don't you have to write code to use it? Nope. Windows and SQL Azure are made up of various components. Some of those components allow you to write and deploy code (like Compute) and others don't. We have lots of customers using Windows Azure storage as a backup, to securely share files instead of using DropBox, to distribute videos or code or firmware, and more. Others use our High Performance Computing (HPC) offering to rent a supercomputer when they need one. You can even throw workloads at that using Excel! In addition there are lots of other components in Windows Azure you can use, from the Windows Azure Media Services to others. More here: https://www.windowsazure.com/en-us/home/scenarios/saas/ Myth 5: Windows Azure is just another form of "vendor lock-in" Windows Azure uses .NET, OSS languages and standard interfaces for the code. Sure, you're not going to take the code line-for-line and run it on a mainframe, but it's standard code that you write, and can port to something else. And the data is yours - you can bring it back whever you want. It's either in text or binary form, that you have complete control over. There are no licenses - you can "pay as you go", and when you're done, you can leave the service and take all your code, data and IP with you.   So go out there, read up, try it. Use it where it works. And don't believe everything you hear - sometimes the Internet doesn't get it all correct. :)

• Can Microsoft Build Appliances?

  - by andrewbrust

  Billy Hollis, my Visual Studio Live! colleague and fellow Microsoft Regional Director said recently, and I am paraphrasing, that the computing world, especially on the consumer side, has shifted from one of building hardware and software that makes things possible to do, to building products and technologies that make things easy to do.  Billy crystalized things perfectly, as he often does. In this new world of “easy to do,” Apple has done very well and Microsoft has struggled.  In the old world, customers wanted a Swiss Army Knife, with the most gimmicks and gadgets possible.  In the new world, people want elegantly cutlery.  They may want cake cutters and utility knives too, but they don’t want one device that works for all three tasks.  People don’t want tools, they want utensils.  People don’t want machines.  They want appliances. Microsoft Appliances: They Do Exist Microsoft has built a few appliance-like devices.  I would say XBox 360 is an appliance,  It’s versatile, mind you, but it’s the kind of thing you plug in, turn on and use, as opposed to set-up, tune, and open up to upgrade the internals.  Windows Phone 7 is an appliance too.  It’s a true smartphone, unlike Windows Mobile which was a handheld computer with a radio stack.  Zune is an appliance too, and a nice one.  It hasn’t attained much traction in the market, but that’s probably because the seminal consumer computing appliance -- the iPod – got there so much more quickly. In the embedded world, Mediaroom, Microsoft’s set-top product for the cable industry (used by AT&T U-Verse and others) is an appliance.  So is Microsoft’s Sync technology, used in Ford automobiles.  Even on the enterprise side, Microsoft has an appliance: SQL Server Parallel Data Warehouse Edition (PDW) combines Microsoft software with select OEMs’ server, networking and storage hardware.  You buy the appliance units from the OEMs, plug them in, connect them and go. I would even say that Bing is an appliance.  Not in the hardware sense, mind you.  But from the software perspective, it’s a single-purpose product that you visit or run, use and then move on.  You don’t have to install it (except the iOS and Android native apps where it’s pretty straightforward), you don’t have to customize it, you don’t have to program it.  Basically, you just use it. Microsoft Appliances that Should Exist But Microsoft builds a bunch of things that are not appliances.  Media Center is not an appliance, and it most certainly should be.  Instead, it’s an app that runs on Windows 7.  It runs full-screen and you can use this configuration to conceal the fact that Windows is under it, but eventually something will cause you to abandon that masquerade (like Patch Tuesday). The next version of Windows Home Server won’t, in my opinion, be an appliance either.  Now that the Drive Extender technology is gone, and users can’t just add and remove drives into and from a single storage pool, the product is much more like a IT server and less like an appliance-premised one.  Much has been written about this decision by Microsoft.  I’ll just sum it up in one word: pity. Microsoft doesn’t have anything remotely appliance-like in the tablet category, either.  Until it does, it likely won’t have much market share in that space either.  And of course, the bulk of Microsoft’s product catalog on the business side is geared to enterprise machines and not personal appliances. Appliance DNA: They Gotta Have It. The consumerization of IT is real, because businesspeople are consumers too.  They appreciate the fit and finish of appliances at home, and they increasingly feel entitled to have it at work too.  Secure and reliable push email in a smartphone is necessary, but it isn’t enough.  People want great apps and a pleasurable user experience too.  The full Microsoft Office product is needed at work, but a PC with a keyboard and mouse, or maybe a touch screen that uses a stylus (or requires really small fingers), to run Office isn’t enough either.  People want a flawless touch experience available for the times they want to read and take quick notes.  Until Microsoft realizes this fully and internalizes it, it will suffer defeats in the consumer market and even setbacks in the business market.  Think about how slow the Office upgrade cycle is…now imagine if the next version of Office had a first-class alternate touch UI and consider the possible acceleration in adoption rates. Can Microsoft make the appliance switch?  Can the appliance mentality become pervasive at the company?  Can Microsoft hasten its release cycles dramatically and shed the “some assembly required” paradigm upon which many of its products are based?  Let’s face it, the chances that Microsoft won’t make this transition are significant. But there are also encouraging signs, and they should not be ignored.  The appliances we have already discussed, especially Xbox, Zune and Windows Phone 7, are the most obvious in this regard.  The fact that SQL Server has an appliance SKU now is a more subtle but perhaps also more significant outcome, because that product sits so smack in the middle of Microsoft’s enterprise stack.  Bing is encouraging too, especially given its integrated travel, maps and augmented reality capabilities.  As Bing gains market share, Microsoft has tangible proof that it can transform and win, even when everyone outside the company, and many within it, would bet otherwise. That Great Big Appliance in the Sky Perhaps the most promising (and evolving) proof points toward the appliance mentality, though, are Microsoft’s cloud offerings -- Azure and BPOS/Office 365.  While the cloud does not represent a physical appliance (quite the opposite in fact) its ability to make acquisition, deployment and use of technology simple for the user is absolutely an embodiment of the appliance mentality and spirit.  Azure is primarily a platform as a service offering; it doesn’t just provide infrastructure.  SQL Azure does likewise for databases.  And Office 365 does likewise for SharePoint, Exchange and Lync. You don’t administer, tune and manage servers; instead, you create databases or site collections or mailboxes and start using them. Upgrades come automatically, and it seems like releases will come more frequently.  Fault tolerance and content distribution is just there.  No muss.  No fuss.  You use these services; you don’t have to set them up and think about them.  That’s how appliances work.  To me, these signs point out that Microsoft has the full capability of transforming itself.  But there’s a lot of work ahead.  Microsoft may say they’re “all in” on the cloud, but the majority of the company is still oriented around its old products and models.  There needs to be a wholesale cultural transformation in Redmond.  It can happen, but product management, program management, the field and executive ranks must unify in the effort. So must partners, and even customers.  New leaders must rise up and Microsoft must be able to see itself as a winner.  If Microsoft does this, it could lock-in decades of new success, and be a standard business school case study for doing so.  If not, the company will have missed an opportunity, and may see its undoing.

In my opinion, Apple's iOS has changed everything in Mobile BI.  Yes Blackberry, Android and Symbian and all the rest have their place in the market but I believe that increasingly consumers (not IT departments) influence BI decision making processes.  Consumers are choosing the iPhone and the iPad. The number of iPads I see in business meetings now is staggering.  Some use it for email and note taking and others are starting to use corporate applications.  The possibilities for Mobile BI are countless and I would expect to see iPads enterprise-wide over the next few years.   These new devices will provide just-in-time access to critical business information.  Front-line managers interacting with customers, suppliers, patients or citizens will have information literally at their fingertips. I've experimented with several mobile BI tools.  They look cool but like their Executive Information System (EIS) predecessors of the 1990's these tools lack a backbone and a plausible integration strategy.  EIS was a viral technology in the early 1990's.  Executives from every industry and job function were showcasing their dashboards to fellow co-workers and colleagues at the country club.  Just like the iPad, every senior manager wanted one.  EIS wasn't a device however, it was a software application.   EIS quickly faded into the software sunset as it lacked integration with corporate information systems.  BI servers  replaced EIS because the technology focused on the heavy data lifting of integrating, normalizing, aggregating and managing large, complex data volumes.  The devices are here to stay. The cute stand-alone mobile BI tools, not so much. If all you're looking to do is put Excel files on your iPad, there are plenty of free tools on the market.  You'll look cool at your next management meeting but after a few weeks, the cool factor will fade away and you'll be wondering how you will ever maintain it.  If however you want secure, consistent, reliable information on your iPad, you need an integration strategy and a way to model the data.  BI Server technologies like the Oracle BI Foundation is a market leading approach to tackle that issue. I liken the BI mobility frenzy to buying classic cars.  Classic Cars have two buying groups - teenagers and middle-age folks looking to tinker.  Teenagers look at the pin-stripes and the paint job while middle-agers (like me)  kick the tires a bit and look under the hood to check out the quality and reliability of the engine.  Mobile BI tools sure look sexy but don't go very far without an engine and a transmission or an integration strategy. The strategic question in Mobile BI is can these startups build a motor and transmission faster than Oracle can re-paint the car?  Oracle has a great engine and a transmission that connects to all enterprise information assets.  We're working on the new paint job and are excited about the possibilities.  Just as vertical integration worked in the automotive business, it too works in the technology industry.

• Are IE 9 will have a place in heart of user ?

  - by anirudha

  in a advertisement of IE 9 MSFT compare two product first is their IE9 and second is chrome 6. I know 6 is not currently [9] but no objection because may be they make ads when 6 is currently version and have RC or beta in their hands. on IE 9 test-drive website they show many of people ads to show the user that IE9 is performance better or other chrome or Firefox not. well they not compare with Firefox because last days firefox not still in news and search trends like before RC release many of user googling for them. Well I myself found IE9 perform smoother then chrome. but what MSFT do after IE9 nothing they waiting for IE 10 not for give updates not as well as Google chrome and Firefox. Are IE9 have anything new for Developer even a small or big. well they tell you blah or useless things everytime when they make for next version no matter for you but a matter for them because they add a new thing even useless for developer. I am not have any feeling with IE bad but I like to make reviews as well as I can make. I show you something who I experience with IE and someother browser like Chrome and Firefox. IE 9 still have no plugin as well as other provided like Firefox have Firebug a great utilities who is best option for developer to debug their code. IE9 developer tool is good but still you never customize them or readymade customization available to work as in firefox many of person make customization for firebug like example :- firepicker for picking color in firebug , firebug autocomplete for intellisense like feature when you write JavaScript inside console panel , pixelperfect , firequery , sitepoint reference and many other great example we all love to use. as other things that Firefox give many things customizable like themes , ui and many thing customization means more thing user or developer want to make themselves and more contribution make them better software so Firefox is great because customization is a great thing inside firefox and chrome. if you read some post of developer on MSDN to what’s new in IE 9 developer tool that you feel they are joking whenever you see some other things of Firefox and chrome. in a Firefox a plugin perform many much things but in IE still use IE 9 developer tool no other option like in Firefox use Firebug and many other utilities to make development easier and time saving and best as we can do.if you see Firefox page on mozilla that sublines of firefox is high performance easy customization advanced security well you can say what’s performance but there is no comparison with IE because IE have only performance and nothing else. but Firefox have these three thing to make product love. and third thing I really love that security yeah security. from long time before whenever IE6 is no hackproff and many other easily hack IE6 whenever Firefox is secure. I found myself that many of website install a software on client’s computer and they still not know about them so they track everything. sometime they hijack the homepage and make their website as their homepage. sometime they do something and you trying  to go to  any website then they go to their site first. the problem I telling about not long before it’s time of late in 2008 whenever Firefox is much better then IE6. if someone have bad experience with anyone of these software share with us I like to hear your voice. whenever IE still not for use Firefox is a good option for us even user or developer. I not know why someone make next version of IE. IE still have time to go away from Web. Firefox not rude as IE they still believe in user feedback and chrome is also open the door for feedback on their product gooogle Chrome. but what thing they made in IE on user feedback nothing. they still thing to teach what they maked not thing about what user need. if you spent some hour on firefox and chrome then you found what’s matter. what thing you have whenever you use IE or other browser like google chrome and Firefox :- as a user IE give you nothing even tell you blah blah and more blah but still next version of IE means next IE6 for the web. as in Google chrome you find plugins addons or customization to make experience better but in IE9 you can’t customize anything even the themes they have by default. Firefox already have a great list of plugins or addons to make experience better with Web but IE9 have nothing. this means IE9 not for user and other like chrome and firefox give you much better experience then IE. next thing after user is developer. first thing is that all developer want smooth development who save their time not take too perhaps saving.posts on IE9 show that a list of thing improved in IE 9 developer tool but are one developer tool enough for web development so developer need more utilities to solve different different type of puzzle who IE 9 never give like in Firefox you have utilities to do a task even small or big one. in chrome same experience you have but IE9 never give any plugin or utilities to make our work faster even they are new headache for developer because IE not give update as soon as other because in Firefox and in chrome if a bug is reported then they solve them fast and distribute them in next version of software very soon but in IE wait for a long time like IE 9 and IE 8 have no official release between them as update. As my conclusion there is no reason to use IE and adopt 9 again. it’s really not for Developer or user even newbie or smart people. as a rule I want to beware you with IE because it’s my responsibilities to move the thing in good way as I can make. well are you sure that there is no reason or profit they thing to have with IE9  if not why they forget luna [windows xp] user. because they are old nothing they want to force user to give them some money by purchasing a new version of OS. so this a thing why they marketed their software. if you thing about what firefox and chrome want to make : Mozilla's mission is to promote openness, innovation and opportunity on the web. chrome mission we all see whenever we use them. but IE9 is a trick they promote because they want to add something to next version of windows. if somebody like IE9 [even surprised by ads they see or post they read] then they purchase windows soon as they possible. Well you feel that I am opposition of IE9 and favor of chrome and Firefox yeah you feel right I hate IE from a heart not from a pencil. well you get same thing when you have trying three product major I described here Chrome firefox and IE. well don’t believe on the blogs , posts or article who are provided by the merchant or vender’s website. open the eyes read and thing what they talk and feel are they really true. if you confused that compare with some other. now you know the true because no one telling so badly as a user can described who use them not only one who make their feature. always open the eyes don’t believe use your mind and find the truth. thanks for reading my post good bye and take care

• Communities - The importance of exchange and discussion

  Communication with your environment is an essential part of everyone's life. And it doesn't matter whether you are actually living in a rural area in the middle of nowhere, within the pulsating heart of a big city, or in my case on a wonderful island in the Indian Ocean. The ability to exchange your thoughts, your experience and your worries with another person helps you to get different points of view and new ideas on how to resolve an issue you might be confronted with. Benefits of community work What happens to be common sense in your daily life, also applies to your work environment. Working in IT, or ICT as it is called in Mauritius, requires a lot of reading and learning. Not only during your lectures at the university but with your colleagues in a project assignment and hopefully with 'unknown' pals in the universe of online communities. At least I can say that I learned quite a lot from other developers code, their responses in various forums, their numerous blog articles, and while attending local user group meetings. When I started to work as a professional software developer (or engineer some may say) years ago I immediately checked the existence of communities on the programming language, the database technology and other vital information on software development in general. Luckily, it wasn't too difficult to find. My employer had a subscription of the monthly magazines and newsletters of a national organisation which also run the biggest forum in that area. Getting in touch with other developers and reading their common problems but also solutions was a huge benefit to my growth. Image courtesy of Michael Kappel (CC BY-NC 2.0) Active participation and regular contribution to this community gave me some nice advantages, too. Within three years I was listed as a conference speaker at the annual developer's conference and provided several sessions on different topics during consecutive years. Back in 2004, I took over the responsibility and management of the monthly meetings of a regional user group, and organised it for more than two years. Furthermore, I was invited to the newly-founded community program of Microsoft Germany (Community Leader/Insider Program - CLIP). My website on Active FoxPro Pages was nominated in the second batch of online communities. Due to my community work and providing advice to others, I had the honour to be awarded as Microsoft Most Valuable Professional (MVP) - Visual Developer for Visual FoxPro in the years 2006 and 2007. It was a great experience to meet with other like-minded people and I'm really grateful for that. Just in case, more details are listed in my Curriculum Vitae. But this all changed when I moved to Mauritius... Cyber island Mauritius? During the first months in Mauritius I was way too busy to think about community activities at all. First of all, there was the new company that had to be set up, the new staff had to be trained and of course the communication work-flows and so on with the project managers back in Germany had to be sorted out, too. Second, I had to get a grip of my private matters like getting the basics for my new household or exploring the neighbourhood, and last but not least I needed a break from the hectic and intensive work prior to my departure. As soon as the sea literally calmed down, I started to have conversations with my colleagues about communities and user groups. Sadly, it turned out that there were none, or at least no one was aware of any at that time. Oh oh, what did I do? Anyway, having this kind of background and very positive experience with off-line and on-line activities I decided for myself that some day I'm going to found a community in Mauritius for all kind of IT/ICT-related fields. The main focus might be on software development but not on a certain technology or methodology. It was clear to me that it should be an open infrastructure and anyone is welcome to join, to experience, to share and to contribute if they would like to. That was the idea at that time... Ok, fast-forward to recent events. At the end of October 2012 I was invited to an event called Open Days organised by Microsoft Indian Ocean Islands together with other local partners and resellers. There I got in touch with local Technical Evangelist Arnaud Meslier and we had a good conversation on communities during the breaks. Eventually, I left a good impression on him, as we are having chats on Facebook or Skype irregularly. Well, seeing that my personal and professional surroundings have been settled and running smooth, having that great exchange and contact with Microsoft IOI (again), and being really eager to re-animate my intentions from 2007, I recently founded a new community: Mauritius Software Craftsmanship Community - #MSCC It took me a while to settle down with the name but it was obvious that the community should not be attached to one single technology, like ie. .NET user group, Oracle developers, or Joomla friends (these are fictitious names). There are several other reasons why I came up with 'Craftsmanship' as the core topic of this community. The expression of 'engineering' didn't feel right with the fields covered. Software development in all kind of facets is a craft, and therefore demands a lot of practice but also guidance from more experienced developers. It also includes the process of designing, modelling and drafting the ideas. Has to deal with various types of tests and test methodologies, and of course should be focused on flexible and agile ways of acting. In order to meet and to excel a customer's request for a solution. Next, I was looking for an easy way to handle the organisation of events and meeting appointments. Using all kind of social media platforms like Google+, LinkedIn, Facebook, Xing, etc. I was never really confident about their features of event handling. More by chance I stumbled upon Meetup.com and in combination with the other entities (G+ Communities, FB Pages or in Groups) I am looking forward to advertise and manage all future activities here: Mauritius Software Craftsmanship Community This is a community for those who care and are proud of what they do. For those developers, regardless how experienced they are, who want to improve and master their craft. This is a community for those who believe that being average is just not good enough. I know, there are not many 'craftsmen' yet but it's a start... Let's see how it looks like by the end of the year. There are free smartphone apps for Android and iOS from Meetup.com that allow you to keep track of meetings and to stay informed on latest updates. And last but not least, there will be a Trello workspace to collect and share ideas and provide downloads of slides, etc. Sharing is caring! As mentioned, the #MSCC is present in various social media networks in order to cover as many people as possible here in Mauritius. Following is an overview of the current networks: Twitter - Latest updates and quickies Google+ - Community channel Facebook - Community Page LinkedIn - Community Group Trello - Collaboration workspace to share and develop ideas Hopefully, this covers the majority of computer-related people in Mauritius. Please spread the word about the #MSCC between your colleagues, your friends and other interested 'geeks'. Your future looks bright Running and participating in a user group or any kind of community usually provides quite a number of advantages for anyone. On the one side it is very joyful for me to organise appointments and get in touch with people that might be interested to present a little demo of their projects or their recent problems they had to tackle down, and on the other side there are lots of companies that have various support programs or sponsorships especially tailored for user groups. At the moment, I already have a couple of gimmicks that I would like to hand out in small contests or raffles during one of the upcoming meetings, and as said, companies provide all kind of goodies, books free of charge, or sometimes even licenses for communities. Meeting other software developers or IT guys also opens up your point of view on the local market and there might be interesting projects or job offers available, too. A community like the Mauritius Software Craftsmanship Community is great for freelancers, self-employed, students and of course employees. Meetings will be organised on a regular basis, and I'm open to all kind of suggestions from you. Please leave a comment here in blog or join the conversations in the above mentioned social networks.

• Corsair Hackers Reboot

  It wasn't easy for me to attend but it was absolutely worth to go. The Linux User Group of Mauritius (LUGM) organised another get-together for any open source enthusiast here on the island. Strangely named "Corsair Hackers Reboot" but it stands for a positive cause: "Corsair Hackers Reboot Event A collaborative activity involving LUGM, UoM Computer Club, Fortune Way Shopping Mall and several geeks from around the island, striving to put FOSS into homes & offices. The public is invited to discover and explore Free Software & Open Source." And it was a good opportunity for me and the kids to visit the east coast of Mauritius, too. Perfect timing It couldn't have been better... Why? Well, for two important reasons (in terms of IT): End of support for Microsoft Windows XP - 08.04.2014 Release of Ubuntu 14.04 Long Term Support - 17.04.2014 Quite funnily, those two IT dates weren't the initial reasons and only during the weeks of preparations we put those together. And therefore it was even more positive to promote the use of Linux and open source software in general to a broader audience. Getting there ... Thanks to the new motor way M3 and all the additional road work which has been completed recently it was very simple to get across the island in a very quick and relaxed manner. Compared to my trips in the early days of living in Mauritius (and riding on a scooter) it was very smooth and within less than an hour we hit Centrale de Flacq. Well, being in the city doesn't necessarily mean that one has arrived at the destination. But thanks to modern technology I had a quick look on Google Maps, and we finally managed to get a parking behind the huge bus terminal in Flacq. From there it was just a short walk to Fortune Way. The children were trying to count the number of buses... Well, lots and lots of buses - really impressive actually. What was presented? There were different areas set up. Right at the entrance one's attention was directly drawn towards the elevated hacker's stage. Similar to rock stars performing their gig there was bunch of computers, laptops and networking equipment in order to cater the right working conditions for coding/programming challenge(s) on the one hand and for the pen-testing or system hacking competition on the other hand. Personally, I was very impresses that actually Nitin took care of the pen-testing competition. He hardly started one year back with Linux in general, and Kali Linux specifically. Seeing his personal development from absolute newbie to a decent Linux system administrator within such a short period of time, is really impressive. His passion to open source software made him a living. Next, clock-wise seen, was the Kid's Corner with face-painting as the main attraction. Additionally, there were numerous paper print outs to colour. Plus a decent workstation with the educational suite GCompris. Of course, my little ones were into that. They already know GCompris since a while as they are allowed to use it on an IGEL thin client terminal here at home. To simplify my life, I set up GCompris as full-screen guest session on the server, and they can pass the login screen without any further obstacles. And because it's a thin client hooked up to a XDMCP remote session I don't have to worry about the hardware on their desk, too. The next section was the main attraction of the event: BYOD - Bring Your Own Device Well, compared to the usual context of BYOD the corsairs had a completely different intention. Here, you could bring your own laptop and a team of knowledgeable experts - read: geeks and so on - offered to fully convert your system on any Linux distribution of your choice. And even though I came later, I was told that the USB pen drives had been in permanent use. From being prepared via dd command over launching LiveCD session to finally installing a fresh Linux system on bare metal. Most interestingly, I did a similar job already a couple of months ago, while upgrading an existing Windows XP system to Xubuntu 13.10. So far, the female owner is very happy and enjoys her system almost every evening to go shopping online, checking mails, and reading latest news from the Anime world. Back to the Hackers event, Ish told me that they managed approximately 20 conversion during the day. Furthermore, Ajay and others gladly assisted some visitors with some tricky issues and by the end of the day you can call is a success. While I was around, there was a elderly male visitor that got a full-fledged system conversion to a Linux system running completely in French language. A little bit more to the centre it was Yasir's turn to demonstrate his Arduino hardware that he hooked up with an experimental electrical circuit board connected to an LCD matrix display. That's the real spirit of hacking, and he showed some minor adjustments on the fly while demo'ing the system. Also, very interesting there was a thermal sensor around. Personally, I think that platforms like the Arduino as well as the Raspberry Pi have a great potential at a very affordable price in order to bring a better understanding of electronics as well as computer programming to a broader audience. It would be great to see more of those experiments during future activities. And last but not least there were a small number of vendors. Amongst them was Emtel - once again as sponsor of the general internet connectivity - and another hardware supplier from Riche Terre shopping mall. They had a good collection of Android related gimmicks, like a autonomous web cam that can convert any TV with HDMI connector into an online video chat system given WiFi. It's actually kind of awesome to have a Skype or Google hangout video session on the big screen rather than on the laptop. Some pictures of the event LUGM: Great conversations on Linux, open source and free software during the Corsair Hackers Reboot LUGM: Educational workstation running GCompris suite attracted the youngest attendees of the day. Of course, face painting had to be done prior to hacking... LUGM: Nadim demoing some Linux specifics to interested visitors. Everyone was pretty busy during the whole day LUGM: The hacking competition, here pen-testing a wireless connection and access point between multiple machines LUGM: Well prepared workstations to be able to 'upgrade' visitors' machines to any Linux operating system Final thoughts Gratefully, during the preparations of the event I was invited to leave some comments or suggestions, and the team of the LUGM did a great job. The outdoor banner was a eye-catcher, the various flyers and posters for the event were clearly written and as far as I understood from the quick chats I had with Ish, Nadim, Nitin, Ajay, and of course others all were very happy about the event execution. Great job, LUGM! And I'm already looking forward to the next Corsair Hackers Reboot event ... Crossing fingers: Very soon and hopefully this year again :) Update: In the media The event had been announced in local media, too. L'Express: Salon informatique: Hacking Challenge à Flacq

• 5 Ways Android Still Disappoints (Me)

  - by TStewartDev

  Let me make this clear: I'm annoyed with Apple. I don't like their current policies and I don't like where Steve Jobs is taking the company. In general, I don't like it when any one company gets too much control in a market. When that happens, the leading company dictates the game and as consumers, our options all but disappear. That said, I'm still going to buy a new iPhone next week. My Apple-hating friends seem to desperately want me to go Android instead, but frankly, it's not good enough for me, and here are the reasons why. The Modern WinMo One of the reasons that Microsoft has identified for Windows Mobile's rapid decline is the breadth of hardware. They exercised little control over manufacturer's implementations. In theory, that sounds great. We as consumers have lots of choice. In practice, though, it meant among other things that updates to the devices were left up to the manufacturers. As a result, that rarely happened. (I'm still bitter at Toshiba for leaving me hanging back in 2002.) And now, Google is doing the same thing with Android. Case in point: my wife has a Motorola Backflip that we bought in April. It was released in March. Motorola says it will get Android 2.1 "sometime in Q3". Great. Meanwhile, I pull down the latest version of iPhone OS (now iOS) and install it the same day it's released. You may say that I can't judge Android by one lazy manufacturer. Yup, I sure can. With Apple, my original iPhone has been supported perfectly for 3 years. With Android, I will have to wait for upgrades after Google releases them, possibly indefinitely. Not cool. AT&T We signed a new contract with AT&T in April to get my wife's phone. I've had a reasonable experience with them. I don't imagine my experience with Verizon would be any better, and I'm relatively confident that Sprint doesn't have the coverage it takes to work well for us. The fact is, AT&T, for whatever reason, doesn't have jack for Android phones. May not be Android's fault, but it's still a shortcoming that prevents me from having it just like the iPhone's exclusivity keeps some folks on other networks from having it. Innovation? What Innovation? Android has a nice dashboard and a great notification system and… nothing else original. I keep reading about how disappointing the iPhone is nowadays. "It has no innovation," people say. Who does? Android has modeled its behavior after the iPhone. That's fine, but if all you've got is a similar product and I'm invested both skill-wise and app-wise in my current platform, why should I change? Microsoft's new Windows Phone 7 looks somewhat innovative, and I'm pretty excited to see what they'll bring to the table, but that's another six months away, at least. I've got a 3 year old phone that has some annoying issues now (thanks to recent encounters with water). I need a new phone now. Is This Going to Work? There's no shortage of criticism of Apple over its App Store policies, and I've vented my own anger about it. However, I will give them credit: their screening of apps has done a great job of weeding out the crap and gives an excellent indication that the app will work on my device. How about Android? Nope. It might work on your phone. Maybe. You'll have to try it to see. Get burned by it? Well, write a nasty review to try to keep others from making the mistake you did. If you don't mind doing that stuff, then Android is the platform for you. Personally, I'd rather have a receptionist screening out the telemarketing and survey calls than hang up on them myself, but that's your call. Slow, Slowing, Slower All this yapping about multitasking. This is an area I've been on Apple's side from the beginning. Sorry folks, but this is the number one reason I hated Windows Mobile: the longer you use it, the slower it gets because it doesn't kill apps. I'm with Steve Jobs on this one: if you see a task manager, we're doing it wrong. I don't want to have to manually kill apps. I hate doing that on Windows let alone on a mobile device. To me, priority one should be keeping the device speedy. Waiting for your device to respond is unacceptable. Bonus! Taken from iPhone Letdown? 8 Things Apple Didn't Announce, here are my responses: 4G Yeah, let me know if your area actually has it. I live in Lincoln, Nebraska. No carrier is going to have 4G here for at least 3 years. Meanwhile, you still get to pay for it. Yay! Cloud iTunes/OTA Sync You got me here. Of course, whether or not your Android device will be able to do it is always a good question. 3G Video Chat You got me here, too. I'm sure you spent countless hours in front of your phone with video chat. Also, I can't wait for the "No Video Chat While Driving" laws. Mobile Hotspot This is a neat feature, but as the author points out, it's left up to the carrier whether to implement it or not. Pretty sure any Android phones that come to AT&T won't have this enabled in the foreseeable future. Is Verizon even allowing this? I just figured Sprint was because they're failing so hard at keeping customers. Free MobileMe I use Google's services with my iPhone. The only people I know who use MobileMe are Apple fanboys and fangirls. If you choose to pay for a service that you can get for free, that's your decision, not Apple's. Voice Input Voice input has been available on phones (even "dumb" phones) for years now. iPhone does have the ability, though limited. Why don't I hear people telling their phones what to do? Maybe because it's still easier to use your fingers than talk to it. Get back to me when this becomes an important feature. Free Navigation Maybe this will be a bigger deal to me now that I'm getting a phone with GPS, but when using my buddy's 3gs, Google maps has worked just fine. Maybe I just don't trust turn-by-turn navigation enough to want it. Dashboard The only legitimate complaint on this list, to me. iPhone's home screen is pathetic, doubly so for the iPad. What a waste of perfectly usable space. I also want to add notifications to this list. Android's notification panel is far superior to the iPhone's. I don't want to hunt all over my screen to find little red dots. Put 'em in one place, Apple.

• Why people don't patch and upgrade?!?

  - by Mike Dietrich

  Discussing the topic "Why Upgrade" or "Why not Upgrade" is not always fun. Actually the arguments repeat from customer to customer. Typically we hear things such as: A PSU or Patch Set introduces new bugs A new PSU or Patch Set introduces new features which lead to risk and require application verification  Patching means risk Patching changes the execution plans Patching requires too much testing Patching is too much work for our DBAs Patching costs a lot of money and doesn't pay out And to be very honest sometimes it's hard for me to stay calm in such discussions. Let's discuss some of these points a bit more in detail. A PSU or Patch Set introduces new bugsWell, yes, that is true as no software containing more than some lines of code is bug free. This applies to Oracle's code as well as too any application or operating system code. But first of all, does that mean you never patch your OS because the patch may introduce new flaws? And second, what is the point of saying "it introduces new bugs"? Does that mean you will never get rid of the mean issues we know about and we fixed already? Scroll down from MOS Note:161818.1 to the patch release you are on, no matter if it's 10.2.0.4 or 11.2.0.3 and check for the Known Issues And Alerts.Will you take responsibility to know about all these issues and refuse to upgrade to 11.2.0.4? I won't. A new PSU or Patch Set introduces new featuresOk, we can discuss that. Offering new functionality within a database patch set is a dubious thing. It has advantages such as in 11.2.0.4 where we backported Database Redaction to. But this is something you will only use once you have an Advanced Security license. I interpret that statement I've heard quite often from customers in a different way: People don't want to get surprises such as new behaviour. This certainly gives everybody a hard time. And we've had many examples in the past (SESSION_CACHED_CURSROS in 10.2.0.4,  _DATAFILE_WRITE_ERRORS_CRASH_INSTANCE in 11.2.0.2 and others) where those things weren't documented, not even in the README. Thanks to many friends out there I learned about those as well. So new behaviour is the topic people consider as risky - not really new features. And just to point this out: A PSU never brings in new features or new behaviour by definition! Patching means riskDoes it really mean risk? Yes, there were issues in the past (and sometimes in the present as well) where a patch didn't get installed correctly. But personally I consider it way more risky to not patch. Keep that in mind: The day Oracle publishes an PSU (or CPU) containing security fixes all the great security experts out there go public with their findings as well. So from that day on even my grandma can find out about those issues and try to attack somebody. Now a lot of people say: "My database does not face the internet." And I will answer: "The enemy is sitting already behind your firewalls. And knows potentially about these things." My statement: Not patching introduces way more risk to your environment than patching. Seriously! Patching changes the execution plansDo they really? I agree - there's a very small risk for this happening with Patch Sets. But not with PSUs or CPUs as they contain no optimizer fixes changing behaviour (but they may contain fixes curing wrong-query-result-bugs). But what's the point of a changing execution plan? In Oracle Database 11g it is so simple to be prepared. SQL Plan Management is a free EE feature - so once that occurs you'll put the plan into the Plan Baseline. Basta! Yes, you wouldn't like to get such surprises? Than please use the SQL Performance Analyzer (SPA) from Real Application Testing and you'll detect that easily upfront in minutes. And not to forget this, a plan change can also be very positive!Yes, there's a little risk with a database patchset - and we have many possibilites to detect this before patching. Patching requires too much testingWell, does it really? I have seen in the past 12 years how people test. There are very different efforts and approaches on this. I have seen people spending a hell of money on licenses or on project team staffing. And I have seen people sailing blindly without any tests just going the John-Wayne-approach.Proper tools will allow you to test easily without too much efforts. See the paragraph above. We have used Real Application Testing in so many customer projects reducing the amount of work spend on testing by over 50%. But apart from that at some point you will have to stop testing. If you don't you'll get lost and you'll burn money. There's no 100% guaranty. You will have to deal with a little risk as reaching the final 5% of certainty will cost you the same as it did cost to reach 95%. And doing this will lead to abnormal long product cycles that you'll run behind forever. And this will cost even more money. Patching is too much work for our DBAsPatching is a lot of work. I agree. And it's no fun work. It's boring, annoying. You don't learn much from that. That's why you should try to automate this task. Use the Database's Lifecycle Management Pack. And don't cry about the fact that it costs money. Yes it does. But it will ease the process and you'll save a lot of costs as you don't waste your valuable time with patching. Or use Oracle Database 12c Oracle Multitenant and patch either by unplug/plug or patch an entire container database with all PDBs with one patch in one task. We have customer reference cases proofing it saved them 75% of time, effort and cost since they've used Lifecycle Management Pack. So why don't you use it? Patching costs a lot of money and doesn't pay outWell, see my statements in the paragraph above. And it pays out as flying with a database with 100 known critical flaws in it which are already fixed by Oracle (such as in the Oct 2013 PSU for Oracle Database 12c) will cost ways more in case of failure or even data loss. Bet with me? Let me finally ask you some questions. What cell phone are you using and which OS does it run? Do you have an iPhone 5 and did you upgrade already to iOS 7.0.3? I've just encountered on mine that the alarm (which I rely on when traveling) has gotten now a dependency on the physical switch "sound on/off". If it is switched to "off" physically the alarm rings "silently". What a wonderful example of a behaviour change coming in with a patch set. Will this push you to stay with iOS5 or iOS6? No, because those have security flaws which won't be fixed anymore. What browser are you surfing with? Do you use Mozilla 3.6? Well, congratulations to all the hackers. It will be easy for them to attack you and harm your system. I'd guess you have the auto updater on.  Same for Google Chrome, Safari, IE. Right? -Mike The T.htmtableborders, .htmtableborders td, .htmtableborders th {border : 1px dashed lightgrey ! important;} html, body { border: 0px; } body { background-color: #ffffff; } img, hr { cursor: default }

Some of the key features are: High performance rendering. Animaitons. Scrolling/Zoooming. Support for unlimited number of data series and data points. Support for unlimited number of chart axes. True DateTime Axis. Logarithmic and Reversed axis scale. Large set of chart types - Bar, Column, Pie, Line, Spline, Area, Scatter, Bubble, Radar, Polar. Financial Charts - Stock Chart and Candlestick Chart. The different chart types can be easily combined.  System Requirements Browser Support jqChart supports all major browsers: Internet Explorer - 6+ Firefox Google Chrome Opera Safari jQuery version support jQuery JavaScript framework is required. We recommend using the latest official stable version of the jQuery library. Visual Studio Support jqChart for ASP.NET does not require using Visual Studio. You can use your favourite code editor. Still, the product has been tested with several versions of Visual Studio .NET and you can find the list of supported versions below: Visual Studio 2008 Visual Studio 2010 Visual Studio 2012 ASP.NET Web Forms support Supported version - ASP.NET Web Forms 3.5, 4.0 and 4.5 Installation Download and unzip the contents of the archive to any convenient location. The package contains the following folders: [bin] - Contains the assembly DLLs of the product (JQChart.Web.dll) for WebForms 3.5, 4.0 and 4.5. This is the assembly that you can reference directly in your web project (or better yet, add it to your ToolBox and then drag & drop it from there). [js] - The javascript files of jqChart and jqRangeSlider (and the needed libraries). You need to include them in your ASPX page, in order to gain the client side functionality of the chart. The first file is "jquery-1.5.1.min.js" - this is the official jQuery library. jqChart is built upon jQuery library version 1.4.3. The second file you need is the "excanvas.js" javascript file. It is used from the versions of IE, which dosn't support canvas graphics. The third is the jqChart javascript code itself, located in "jquery.jqChart.min.js". The last one is the jqRangeSlider javascript, located in "jquery.jqRangeSlider.min.js". It is used when the chart zooming is enabled. [css] - Contains the Css files that the jqChart and the jqRangeSlider need. [samples] - Contains some examples that use the jqChart.

• User Input That Involves A ' ' Causes A Substring Out Of Range Error

  - by Greenhouse Gases

  Hi Stackoverflow people. You have already helped me quite a bit but near the end of writing this program I have somewhat of a bug. You see in order to read in city names with a space in from a text file I use a '/' that is then replaced by the program for a ' ' (and when the serializer runs the opposite happens for next time the program is run). The problem is when a user inputs a name too add, search for, or delete that contains a space, for instance 'New York' I get a Debug Assertion Error with a substring out of range expression. I have a feeling it's to do with my correctCase function, or setElementsNull that looks at the string until it experiences a null element in the array, however ' ' is not null so I'm not sure how to fix this and I'm going a bit insane. Any help would be much appreciated. Here is my code: // U08221.cpp : main project file. #include "stdafx.h" #include <_iostream> #include <_string> #include <_fstream> #include <_cmath> using namespace std; class locationNode { public: string nodeCityName;

} locationNode() // NULL constructor { } void swapProps(locationNode *node2) { locationNode place; place.nodeCityName = this->nodeCityName; place.nodeLati = this->nodeLati; place.nodeLongi = this->nodeLongi;

} void modify(string name) { this->nodeCityName = name; } void modify(double latlon, int mod) { switch(mod) { case 2: this->nodeLati = latlon; break; case 3: this->nodeLongi = latlon; break; } } void correctCase() // Correct upper and lower case letters of input { int MAX_SIZE = 35;

• Can't get the L2TP IPSEC up and running

  - by Maciej Swic

  i have an Ubuntu 11.10 (oneiric) server running on a ReadyNAS. Im planning to use this to accept ipsec+l2tp connections through a router. However, the connection is failing somewhere half through. Using Openswan IPsec U2.6.28/K3.0.0-12-generic and trying to connect with an iOS 5 iPhone 4S. This is how far i can get: auth.log: Jan 19 13:54:11 ubuntu pluto[1990]: added connection description "PSK" Jan 19 13:54:11 ubuntu pluto[1990]: added connection description "L2TP-PSK-NAT" Jan 19 13:54:11 ubuntu pluto[1990]: added connection description "L2TP-PSK-noNAT" Jan 19 13:54:11 ubuntu pluto[1990]: added connection description "passthrough-for-non-l2tp" Jan 19 13:54:11 ubuntu pluto[1990]: listening for IKE messages Jan 19 13:54:11 ubuntu pluto[1990]: NAT-Traversal: Trying new style NAT-T Jan 19 13:54:11 ubuntu pluto[1990]: NAT-Traversal: ESPINUDP(1) setup failed for new style NAT-T family IPv4 (errno=19) Jan 19 13:54:11 ubuntu pluto[1990]: NAT-Traversal: Trying old style NAT-T Jan 19 13:54:11 ubuntu pluto[1990]: adding interface eth0/eth0 192.168.19.99:500 Jan 19 13:54:11 ubuntu pluto[1990]: adding interface eth0/eth0 192.168.19.99:4500 Jan 19 13:54:11 ubuntu pluto[1990]: adding interface lo/lo 127.0.0.1:500 Jan 19 13:54:11 ubuntu pluto[1990]: adding interface lo/lo 127.0.0.1:4500 Jan 19 13:54:11 ubuntu pluto[1990]: adding interface lo/lo ::1:500 Jan 19 13:54:11 ubuntu pluto[1990]: adding interface eth0/eth0 2001:470:28:81:a00:27ff:* Jan 19 13:54:11 ubuntu pluto[1990]: loading secrets from "/etc/ipsec.secrets" Jan 19 13:54:11 ubuntu pluto[1990]: loading secrets from "/var/lib/openswan/ipsec.secrets.inc" Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: received Vendor ID payload [RFC 3947] method set to=109 Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: received Vendor ID payload [draft-ietf-ipsec-nat-t-ike] method set to=110 Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: ignoring unknown Vendor ID payload [8f8d83826d246b6fc7a8a6a428c11de8] Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: ignoring unknown Vendor ID payload [439b59f8ba676c4c7737ae22eab8f582] Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: ignoring unknown Vendor ID payload [4d1e0e136deafa34c4f3ea9f02ec7285] Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: ignoring unknown Vendor ID payload [80d0bb3def54565ee84645d4c85ce3ee] Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: ignoring unknown Vendor ID payload [9909b64eed937c6573de52ace952fa6b] Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: received Vendor ID payload [draft-ietf-ipsec-nat-t-ike-03] meth=108, but already using method 110 Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: received Vendor ID payload [draft-ietf-ipsec-nat-t-ike-02] meth=107, but already using method 110 Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: received Vendor ID payload [draft-ietf-ipsec-nat-t-ike-02_n] meth=106, but already using method 110 Jan 19 14:04:31 ubuntu pluto[1990]: packet from 95.*.*.233:500: received Vendor ID payload [Dead Peer Detection] Jan 19 14:04:31 ubuntu pluto[1990]: "PSK"[1] 95.*.*.233 #1: responding to Main Mode from unknown peer 95.*.*.233 Jan 19 14:04:31 ubuntu pluto[1990]: "PSK"[1] 95.*.*.233 #1: transition from state STATE_MAIN_R0 to state STATE_MAIN_R1 Jan 19 14:04:31 ubuntu pluto[1990]: "PSK"[1] 95.*.*.233 #1: STATE_MAIN_R1: sent MR1, expecting MI2 Jan 19 14:04:33 ubuntu pluto[1990]: "PSK"[1] 95.*.*.233 #1: NAT-Traversal: Result using draft-ietf-ipsec-nat-t-ike (MacOS X): both are NATed Jan 19 14:04:33 ubuntu pluto[1990]: "PSK"[1] 95.*.*.233 #1: transition from state STATE_MAIN_R1 to state STATE_MAIN_R2 Jan 19 14:04:33 ubuntu pluto[1990]: "PSK"[1] 95.*.*.233 #1: STATE_MAIN_R2: sent MR2, expecting MI3 Jan 19 14:05:03 ubuntu pluto[1990]: ERROR: asynchronous network error report on eth0 (sport=500) for message to 95.*.*.233 port 500, complainant 95.*.*.233: Connection refused [errno 111, origin ICMP type 3 code 3 (not authenticated)] Router config UDP 500, 1701 and 4500 forwarded to 192.168.19.99 (Ubuntu server for ipsec).

• OpenVPN Error : TLS Error: local/remote TLS keys are out of sync: [AF_INET]

  - by Lucidity

  Fist off thanks for reading this, I appreciate any and all suggestions. I am having some serious problems reconnecting to my OpenVPN client using Riseup.net's VPN. I have spent a few days banging my head against the wall in attempts to set this up on my iOS devices....but that is a whole other issue. I was however able to set it up on my Mac OS X specifically on my Windows Vista 32 bit BootCamp VM with relatively little trouble. To originally connect I only had to modify the recommended Config file very slightly (Config file included at the end of this post): - I had to enter the code directly into my config file - And change "dev tap" to "dev tun" So I was connected. (Note - I did test to ensure the VPN was actually working after I originally connected, it was. Also verified the .pem file (inserted as the coding in my config file) for authenticity). I left the VPN running. My computer went to sleep. Today I went to use the internet expecting (possibly incorrectly - I am now unsure if I was wrong to leave it running) to still be connected to the VPN. However I saw immediately I was not. I went to reconnect. And was (am) unable to. My logs after attempting to connect (and getting a connection failed dialog box) show everything working as it should (as far as I can tell) until the end where I get the following lines: Mon Sep 23 21:07:49 2013 us=276809 Initialization Sequence Completed Mon Sep 23 21:07:49 2013 us=276809 MANAGEMENT: >STATE:1379995669,CONNECTED,SUCCESS, OMITTED Mon Sep 23 21:22:50 2013 us=390350 Authenticate/Decrypt packet error: packet HMAC authentication failed Mon Sep 23 21:23:39 2013 us=862180 TLS Error: local/remote TLS keys are out of sync: [AF_INET] VPN IP OMITTED [2] Mon Sep 23 21:23:57 2013 us=395183 Authenticate/Decrypt packet error: packet HMAC authentication failed Mon Sep 23 22:07:41 2013 us=296898 TLS: soft reset sec=0 bytes=513834601/0 pkts=708032/0 Mon Sep 23 22:07:41 2013 us=671299 VERIFY OK: depth=1, C=US, O=Riseup Networks, L=Seattle, ST=WA, CN=Riseup Networks, [email protected] Mon Sep 23 22:07:41 2013 us=671299 VERIFY OK: depth=0, C=US, O=Riseup Networks, L=Seattle, ST=WA, CN=vpn.riseup.net Mon Sep 23 22:07:46 2013 us=772508 Data Channel Encrypt: Cipher 'BF-CBC' initialized with 128 bit key Mon Sep 23 22:07:46 2013 us=772508 Data Channel Encrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Mon Sep 23 22:07:46 2013 us=772508 Data Channel Decrypt: Cipher 'BF-CBC' initialized with 128 bit key Mon Sep 23 22:07:46 2013 us=772508 Data Channel Decrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Mon Sep 23 22:07:46 2013 us=772508 Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 2048 bit RSA So I have searched for a solution online and I have included what I have attempted below, however I fear (know) I am not knowledgeable enough in this area to fix this myself. I apologize in advance for my ignorance. I do tech support for a living, but not this kind of tech support unfortunately. Other notes and troubleshooting done - - Windows Firewall is disabled completely, as well as other Anti-virus programs - Tor is disabled completely - No Proxies running - Time is correct in all locations - Router Firmware is up to date - Able to connect to the internet and as far as I can tell all necessary ports are open. - No settings have been altered since I was able to connect successfully. - Ethernet as well as wifi connections attempted, resulted in same error. Also tried adding the following lines to my config file (without success or change in error): persist-key persist-tun proto tcp (after reading that this error generally occurs on UDP connections, and is extremely rare on TCP) resolv-retry infinite (thinking the connection may have timed out since the issues occurred after leaving VPN connected during about 10 hrs of computer in sleep mode) All attempts resulted in exact same error code included at the top of this post. The original suggestions I found online stated - (regarding the TLS Error) - This error should resolve itself within 60 seconds, or if not quit wait 120 seconds and try again. (Which isnt the case here...) (regarding the Out of Sync" error) - If you continue to get "out of sync" errors and the link does not come up, then it means that something is probably wrong with your config file. You must use either ping and ping-restart on both sides of the connection, or keepalive on the server side of a client/server connection, in order to gracefully recover from "local/remote TLS keys are out of sync" errors. I wouldn't be surprised if my config file is lacking, or not correct. However I can confirm I followed the instructions to a tee. And was able to connect originally (and have not modified my settings or config file since I was able to connect to when the error began occurring). I have a very simple config file: client dev tun tun-mtu 1500 remote vpn.riseup.net auth-user-pass ca RiseupCA.pem redirect-gateway verb 4 <ca> -----BEGIN CERTIFICATE----- [OMITTED] -----END CERTIFICATE----- </ca> I would really appreciate any help or suggestions. I am at a total loss here, I know I'm asking a lot here. Though I am a new user on this site I help others on many forums including Microsoft's support community and especially Apple's support communities, so I will definitely pass on anything I learn here to help others. Thanks so so so much in advance for reading this.

• Cisco PIX 8.0.4, static address mapping not working?

  - by Bill

  upgrading a working Pix running 5.3.1 to 8.0.4. The memory/IOS upgrade went fine, but the 8.0.4 configuration is not quite working 100%. The 5.3.1 config on which it was based is working fine. Basically, I have three networks (inside, outside, dmz) with some addresses on the dmz statically mapped to outside addresses. The problem seems to be that those addresses can't send or receive traffic from the outside (Internet.) Stuff on the DMZ that does not have a static mapping seems to work fine. So, basically: Inside - outside: works Inside - DMZ: works DMZ - inside: works, where the rules allow it DMZ (non-static) - outside: works But: DMZ (static) - outside: fails Outside - DMZ: fails (So, say, udp 1194 traffic to .102, http to .104) I suspect there's something I'm missing with the nat/global section of the config, but can't for the life of me figure out what. Help, anyone? The complete configuration is below. Thanks for any thoughts! !

• howto only tunnel specific hosts route through openvpn client on tomato

  - by kcome

  I am relatively newbie in networking world although I did coding and know some sysadmin background for a long time. and here I'm only one step from my destination. The whole picture is : at home I use one LinkSys E3000 as the gateway(don't know yet if this is it's name), wireless AP and no other routing/switching devices. It serves 1 PC and 1 Mac with LAN, 1 Mac Mini + 1 iPad + 2 smartphones with WIFI. My goal is use an openvpn client on the E3000 (with tomato firmware) and make my iPad and smartphone's all WiFi traffic through it, and other devices route remain the same non-openvpn route. So far I'm able to connect openvpn client on E3000 to an openvpn server, tunnel all my devices' all traffic through that openvpn connection. What's left is howto selectively route by source IP (at least in my guessing) to the tunnel while don't bother others. I had learned some 'iptables' and 'route' in past few days however without much luck, so here comes my question. Here are some info which will help you get the structure. ifconfig -a output, some useless lines striped, and in the web interface C0:C1:C0:1A:E0:28 is WAN, C0:C1:C0:1A:E0:27 is LAN, C0:C1:C0:1A:E0:29 is 2.4G wifi AP, C0:C1:C0:1A:E0:2A is 5G wifi AP. root@router:/tmp/home/root# ifconfig -a br0 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth0 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:29 UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 eth2 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:2A UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host ppp0 Link encap:Point-to-Point Protocol inet addr:172.200.1.43 P-t-P:172.200.0.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING MULTICAST MTU:1480 Metric:1 vlan1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 vlan2 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:28 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 wl0.1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:29 BROADCAST MULTICAST MTU:1500 Metric:1 brctl show output root@router:/tmp/home/root# brctl show bridge name bridge id STP enabled interfaces br0 8000.c0c1c01ae027 no vlan1 eth1 eth2 before openvpn route-up script root@router:/tmp/home/root# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.200.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 172.200.0.1 0.0.0.0 UG 0 0 0 ppp0 openvpn server push PUSH: Received control message: 'PUSH_REPLY,redirect-gateway,dhcp-option DNS 8.8.8.8,route 172.20.0.1,topology net30,ping 10,ping-restart 120,ifconfig 172.20.0.6 172.20.0.5' openvpn's stock route-up script Apr 24 14:52:06 router daemon.notice openvpn[1768]: /sbin/ifconfig tun11 172.20.0.6 pointopoint 172.20.0.5 mtu 1500 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 72.14.177.29 netmask 255.255.255.255 gw 172.200.0.1 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 0.0.0.0 netmask 128.0.0.0 gw 172.20.0.5 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 128.0.0.0 netmask 128.0.0.0 gw 172.20.0.5 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 172.20.0.1 netmask 255.255.255.255 gw 172.20.0.5 route after openvpn root@router:/tmp/home/root# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.20.0.5 0.0.0.0 255.255.255.255 UH 0 0 0 tun11 72.14.177.29 172.200.0.1 255.255.255.255 UGH 0 0 0 ppp0 172.200.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 172.20.0.1 172.20.0.5 255.255.255.255 UGH 0 0 0 tun11 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 172.20.0.5 128.0.0.0 UG 0 0 0 tun11 128.0.0.0 172.20.0.5 128.0.0.0 UG 0 0 0 tun11 0.0.0.0 172.200.0.1 0.0.0.0 UG 0 0 0 ppp0 something I had noticed and tried: * on the web interface of openvpn client there is an option "Create NAT on tunnel", if i check this, there is the following script (probably executed after openvpn connection established) root@router:/tmp/home/root# cat /tmp/etc/openvpn/fw/client1-fw.sh #!/bin/sh iptables -I INPUT -i tun11 -j ACCEPT iptables -I FORWARD -i tun11 -j ACCEPT iptables -t nat -I POSTROUTING -s 192.168.1.0/255.255.255.0 -o tun11 -j MASQUERADE if i uncheck this option, the last line will not appear.

• My IIS server won't serve SSL sites to some browsers

  - by sbleon

  (Update: This is now cross-posted at http://stackoverflow.com/questions/3355000. This is the more appropriate forum, but StackOverflow gets a lot more traffic.) I've got an IIS 6.0 server that won't serve pages over SSL to some browsers. In Webkit-based browsers on OS X 10.6, I can't load pages at all.

• My IIS server won't serve SSL sites to some browsers

  - by sbleon

  (Update: This is now cross-posted at http://stackoverflow.com/questions/3355000. This is the more appropriate forum, but StackOverflow gets a lot more traffic.)

• Nginx & Apache Cannot get try_files to work with permalinks

  - by tcherokee

  I have been working on this for the past two weeks not and for some reason I cannot seem to get nginx's try_files to work with my wordpress permalinks.

• How to open a server port outside of an OpenVPN tunnel with a pf firewall on OSX (BSD)

  - by Timbo

  I have a Mac mini that I use as a media server running XBMC and serves media from my NAS to my stereo and TV (which has been color calibrated with a Spyder3Express, happy). The Mac runs OSX 10.8.2 and the internet connection is tunneled for general privacy over OpenVPN through Tunnelblick. I believe my anonymous VPN provider pushes "redirect_gateway" to OpenVPN/Tunnelblick because when on it effectively tunnels all non-LAN traffic in- and outbound. As an unwanted side effect that also opens the boxes server ports unprotected to the outside world and bypasses my firewall-router (Netgear SRX5308). I have run nmap from outside the LAN on the VPN IP and the server ports on the mini are clearly visible and connectable. The mini has the following ports open: ssh/22, ARD/5900 and 8080+9090 for the XBMC iOS client Constellation. I also have Synology NAS which apart from LAN file serving over AFP and WebDAV only serves up an OpenVPN/1194 and a PPTP/1732 server. When outside of the LAN I connect to this from my laptop over OpenVPN and over PPTP from my iPhone. I only want to connect through AFP/548 from the mini to the NAS. The border firewall (SRX5308) just works excellently, stable and with a very high throughput when streaming from various VOD services. My connection is a 100/10 with a close to theoretical max throughput. The ruleset is as follows Inbound: PPTP/1723 Allow always to 10.0.0.40 (NAS/VPN server) from a restricted IP range >corresponding to possible cell provider range OpenVPN/1194 Allow always to 10.0.0.40 (NAS/VPN server) from any Outbound: Default outbound policy: Allow Always OpenVPN/1194 TCP Allow always from 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) OpenVPN/1194 UDP Allow always to 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) Block always from NAS to any On the Mini I have disabled the OSX Application Level Firewall because it throws popups which don't remember my choices from one time to another and that's annoying on a media server. Instead I run Little Snitch which controls outgoing connections nicely on an application level. I have configured the excellent OSX builtin firewall pf (from BSD) as follows pf.conf (Apple App firewall tie-ins removed) (# replaced with % to avoid formatting errors) ### macro name for external interface. eth_if = "en0" vpn_if = "tap0" ### wifi_if = "en1" ### %usb_if = "en3" ext_if = $eth_if LAN="{10.0.0.0/24}" ### General housekeeping rules ### ### Drop all blocked packets silently set block-policy drop ### all incoming traffic on external interface is normalized and fragmented ### packets are reassembled. scrub in on $ext_if all fragment reassemble scrub in on $vpn_if all fragment reassemble scrub out all ### exercise antispoofing on the external interface, but add the local ### loopback interface as an exception, to prevent services utilizing the ### local loop from being blocked accidentally. ### set skip on lo0 antispoof for $ext_if inet antispoof for $vpn_if inet ### spoofing protection for all interfaces block in quick from urpf-failed ############################# block all ### Access to the mini server over ssh/22 and remote desktop/5900 from LAN/en0 only pass in on $eth_if proto tcp from $LAN to any port {22, 5900, 8080, 9090} ### Allow all udp and icmp also, necessary for Constellation. Could be tightened. pass on $eth_if proto {udp, icmp} from $LAN to any ### Allow AFP to 10.0.0.40 (NAS) pass out on $eth_if proto tcp from any to 10.0.0.40 port 548 ### Allow OpenVPN tunnel setup over unprotected link (en0) only to VPN provider IPs ### and port ranges pass on $eth_if proto tcp from any to a.b.8.0/24 port 1194:1201 ### OpenVPN Tunnel rules. All traffic allowed out, only in to ports 4100-4110 ### Outgoing pings ok pass in on $vpn_if proto {tcp, udp} from any to any port 4100:4110 pass out on $vpn_if proto {tcp, udp, icmp} from any to any So what are my goals and what does the above setup achieve? (until you tell me otherwise :) 1) Full LAN access to the above ports on the mini/media server (including through my own VPN server) 2) All internet traffic from the mini/media server is anonymized and tunneled over VPN 3) If OpenVPN/Tunnelblick on the mini drops the connection, nothing is leaked both because of pf and the router outgoing ruleset. It can't even do a DNS lookup through the router. So what do I have to hide with all this? Nothing much really, I just got carried away trying to stop port scans through the VPN tunnel :) In any case this setup works perfectly and it is very stable. The Problem at last! I want to run a minecraft server and I installed that on a separate user account on the mini server (user=mc) to keep things partitioned. I don't want this server accessible through the anonymized VPN tunnel because there are lots more port scans and hacking attempts through that than over my regular IP and I don't trust java in general. So I added the following pf rule on the mini: ### Allow Minecraft public through user mc pass in on $eth_if proto {tcp,udp} from any to any port 24983 user mc pass out on $eth_if proto {tcp, udp} from any to any user mc And these additions on the border firewall: Inbound: Allow always TCP/UDP from any to 10.0.0.40 (NAS) Outbound: Allow always TCP port 80 from 10.0.0.40 to any (needed for online account checkups) This works fine but only when the OpenVPN/Tunnelblick tunnel is down. When up no connection is possbile to the minecraft server from outside of LAN. inside LAN is always OK. Everything else functions as intended. I believe the redirect_gateway push is close to the root of the problem, but I want to keep that specific VPN provider because of the fantastic throughput, price and service. The Solution? How can I open up the minecraft server port outside of the tunnel so it's only available over en0 not the VPN tunnel? Should I a static route? But I don't know which IPs will be connecting...stumbles How secure would to estimate this setup to be and do you have other improvements to share? I've searched extensively in the last few days to no avail...If you've read this far I bet you know the answer :)

• ASP.NET MVC 2 Mdel encapsulated within ViewModel Validation

  - by Program.X

  I am trying to get validation to work in ASP.NET MVC 2, but without much success. I have a complex class containing a large number of fields. (Don't ask - this is oneo f those real-world situations best practices can't touch) This would normally be my Model and is a LINQ-to-SQL generated class. Because this is generated code, I have created a MetaData class as per http://davidhayden.com/blog/dave/archive/2009/08/10/AspNetMvc20BuddyClassesMetadataType.aspx. public class ConsultantRegistrationMetadata { [DisplayName("Title")] [Required(ErrorMessage = "Title is required")] [StringLength(10, ErrorMessage = "Title cannot contain more than 10 characters")] string Title { get; set; } [Required(ErrorMessage = "Forename(s) is required")] [StringLength(128, ErrorMessage = "Forename(s) cannot contain more than 128 characters")] [DisplayName("Forename(s)")] string Forenames { get; set; } // ... I've attached this to the partial class of my generated class: [MetadataType(typeof(ConsultantRegistrationMetadata))] public partial class ConsultantRegistration { // ... Because my form is complex, it has a number of dependencies, such as SelectLists, etc. which I have encapsulated in a ViewModel pattern - and included the ConsultantRegistration model as a property: public class ConsultantRegistrationFormViewModel { public Data.ConsultantRegistration ConsultantRegistration { get; private set; } public SelectList Titles { get; private set; } public SelectList Countries { get; private set; } // ... So it is essentially ViewModel=Model My View then has: <p> <%: Html.LabelFor(model => model.ConsultantRegistration.Title) %> <%: Html.DropDownListFor(model => model.ConsultantRegistration.Title, Model.Titles,"(select a Title)") %> <%: Html.ValidationMessage("Title","*") %> </p> <p> <%: Html.LabelFor(model => model.ConsultantRegistration.Forenames) %> <%: Html.TextBoxFor(model => model.ConsultantRegistration.Forenames) %> <%: Html.ValidationMessageFor(model=>model.ConsultantRegistration.Forenames) %> </p> The problem is, the validation attributes on the metadata class are having no effect. I tried doing it via an Interface, but also no effect. I'm beginning to think that the reason is because I am encapsulating my model within a ViewModel. My Controller (Create Action) is as follows: [HttpPost] public ActionResult Create(Data.ConsultantRegistration consultantRegistration) { if (ModelState.IsValid) // this is always true - which is wrong!! { try { consultantRegistration = ConsultantRegistrationRepository.SaveConsultantRegistration(consultantRegistration); return RedirectToAction("Edit", new { id = consultantRegistration.ID, sectionIndex = 2 }); } catch (Exception ex) { ModelState.AddModelError("CreateException",ex); } } return View(new ConsultantRegistrationFormViewModel(consultantRegistration)); } As outlined in the comment, the ModelState.IsValid property always returns true, despite fields with the Validaiton annotations not being valid. (Forenames being a key example). Am I missing something obvious - considering I am an MVC newbie? I'm after the mechanism demoed by Jon Galloway at http://www.asp.net/learn/mvc-videos/video-10082.aspx. (Am aware t is similar to http://stackoverflow.com/questions/1260562/asp-net-mvc-model-viewmodel-validation but that post seems to talk about xVal. I have no idea what that is and suspect it is for MVC 1)

• Android: OutOfMemoryError while uploading video...

  - by AP257

  Hi all, I have the same problem as described here, but I will supply a few more details. While trying to upload a video in Android, I'm reading it into memory, and if the video is large I get an OutOfMemoryError. Here's my code: // get bytestream to upload videoByteArray = getBytesFromFile(cR, fileUriString); public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException { Uri tempuri = Uri.parse(fileUriString); InputStream is = cR.openInputStream(tempuri); byte[] b3 = readBytes(is); is.close(); return b3; } public static byte[] readBytes(InputStream inputStream) throws IOException { ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); // this is storage overwritten on each iteration with bytes int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; int len = 0; while ((len = inputStream.read(buffer)) != -1) { byteBuffer.write(buffer, 0, len); } return byteBuffer.toByteArray(); } And here's the traceback (the error is thrown on the byteBuffer.write(buffer, 0, len) line): 04-08 11:56:20.456: ERROR/dalvikvm-heap(6088): Out of memory on a 16775184-byte allocation. 04-08 11:56:20.456: INFO/dalvikvm(6088): "IntentService[UploadService]" prio=5 tid=17 RUNNABLE 04-08 11:56:20.456: INFO/dalvikvm(6088): | group="main" sCount=0 dsCount=0 s=N obj=0x449a3cf0 self=0x38d410 04-08 11:56:20.456: INFO/dalvikvm(6088): | sysTid=6119 nice=0 sched=0/0 cgrp=default handle=4010416 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:~93) 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.467: WARN/dalvikvm(6088): threadid=17: thread exiting with uncaught exception (group=0x4001b180) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): Uncaught handler: thread IntentService[UploadService] exiting due to uncaught exception 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): java.lang.OutOfMemoryError 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:93) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.496: INFO/Process(4657): Sending signal. PID: 6088 SIG: 3 I guess that as @DroidIn suggests, I need to upload it in chunks. But (newbie question alert) does that mean that I should make multiple PostMethod requests, and glue the file together at the server end? Or can I load the bytestream into memory in chunks, and glue it together in the Android code? If anyone could give me a clue as to the best approach, I would be very grateful.

• adobe flash buider (flex4): Error #2025 or Error: addChild() is not available in this class. Instead

  - by user306584

  Hi, I'm a complete newbie to Flex, so apologies for my dumbness. I've searched for an answer but haven't found anything that seems to be doing the trick. What I'm trying to do: port this example http://www.adobe.com/devnet/air/flex/articles/flex_air_codebase_print.html to Flash Builder 4. All seems to be fine but for one thing. When I use the original code for the Air application <?xml version="1.0" encoding="utf-8"?> <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" creationComplete="onApplicationComplete()"> <fx:Script> <![CDATA[ private static const neededForCompilation:AirGeneralImplementation = null; private function onApplicationComplete():void { var can:MainCanvas = new MainCanvas(); this.addChild(can); can.labelMessage = "Loaded in an AIR Application "; } ]]> </fx:Script> <fx:Declarations> <!-- Place non-visual elements (e.g., services, value objects) here --> </fx:Declarations> </s:WindowedApplication> I get this run time error Error: addChild() is not available in this class. Instead, use addElement() or modify the skin, if you have one. at spark.components.supportClasses::SkinnableComponent/addChild()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\supportClasses\SkinnableComponent.as:1038] If I substitute the code with this.addElement(can); Everything loads well but the first time I try to press any of the buttons on the main canvas I get the following run time error ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. at flash.display::DisplayObjectContainer/getChildIndex() at mx.managers::SystemManager/getChildIndex()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:1665] at mx.managers.systemClasses::ActiveWindowManager/mouseDownHandler()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\systemClasses\ActiveWindowManager.as:437] here's the super simple code for the main canvas <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" creationComplete="init();"> <fx:Declarations> <!-- Place non-visual elements (e.g., services, value objects) here --> </fx:Declarations> <fx:Script source="main.as" /> <mx:Label id="lblMessage" text="The UI from the shared Flex app BothCode" x="433" y="112"/> <s:Button x="433" y="141" click="saveFile();" label="Save File"/> <s:Button x="601" y="141" click="GeneralFactory.getGeneralInstance().airOnlyFunctionality();" label="Air Only"/> </s:Application> Any help would be immensely appreciated. And any pointers to how to setup a project that can compile in both Air and Flash while sharing the same code, all for Flex 4, would also be immensely appreciated. thank you!

• Entity Framework many-to-many using VB.Net Lambda

  - by bgs264

  Hello, I'm a newbie to StackOverflow so please be kind ;) I'm using Entity Framework in Visual Studio 2010 Beta 2 (.NET framework 4.0 Beta 2). I have created an entity framework .edmx model from my database and I have a handful of many-to-many relationships. A trivial example of my database schema is Roles (ID, Name, Active) Members (ID, DateOfBirth, DateCreated) RoleMembership(RoleID, MemberID) I am now writing the custom role provider (Inheriting System.Configuration.Provider.RoleProvider) and have come to write the implementation of IsUserInRole(username, roleName). The LINQ-to-Entity queries which I wrote, when SQL-Profiled, all produced CROSS JOIN statements when what I want is for them to INNER JOIN. Dim query = From m In dc.Members From r In dc.Roles Where m.ID = 100 And r.Name = "Member" Select m My problem is almost exactly described here: http://stackoverflow.com/questions/553918/entity-framework-and-many-to-many-queries-unusable I'm sure that the solution presented there works well, but whilst I studied Java at uni and I can mostly understand C# I cannot understand this Lambda syntax provided and I need to get a similar example in VB. I've looked around the web for the best part of half a day but I'm not closer to my answer. So please can somebody advise how, in VB, I can construct a LINQ statement which would do this equivalent in SQL: SELECT rm.RoleID FROM RoleMembership rm INNER JOIN Roles r ON r.ID = rm.RoleID INNER JOIN Members m ON m.ID = rm.MemberID WHERE r.Name = 'Member' AND m.ID = 101 I would use this query to see if Member 101 is in Role 3. (I appreciate I probably don't need the join to the Members table in SQL but I imagine in LINQ I'd need to bring in the Member object?) UPDATE: I'm a bit closer by using multiple methods: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim count As Integer Using dc As New CBLModel.CBLEntities Dim persons = dc.Members.Where(AddressOf myTest) count = persons.Count End Using System.Diagnostics.Debugger.Break() End Sub Function myTest(ByVal m As Member) As Boolean Return m.ID = "100" AndAlso m.Roles.Select(AddressOf myRoleTest).Count > 0 End Function Function myRoleTest(ByVal r As Role) As Boolean Return r.Name = "Member" End Function SQL Profiler shows this: SQL:BatchStarting SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] RPC:Completed exec sp_executesql N'SELECT [Extent2].[ID] AS [ID], [Extent2].[Name] AS [Name], [Extent2].[Active] AS [Active] FROM [dbo].[RoleMembership] AS [Extent1] INNER JOIN [dbo].[Roles] AS [Extent2] ON [Extent1].[RoleID] = [Extent2].[ID] WHERE [Extent1].[MemberID] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=100 SQL:BatchCompleted SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] I'm not certain why it is using sp_execsql for the inner join statement and why it's still running a select to select ALL members though. Thanks. UPDATE 2 I've written it by turning the above "multiple methods" into lambda expressions then all into one query, like this: Dim allIDs As String = String.Empty Using dc As New CBLModel.CBLEntities For Each retM In dc.Members.Where(Function(m As Member) m.ID = 100 AndAlso m.Roles.Select(Function(r As Role) r.Name = "Doctor").Count > 0) allIDs &= retM.ID.ToString & ";" Next End Using But it doesn't seem to work: "Doctor" is not a role that exists, I just put it in there for testing purposes, yet "allIDs" still gets set to "100;" The SQL in SQL Profiler this time looks like this: SELECT [Project1].* FROM ( SELECT [Extent1].*, (SELECT COUNT(1) AS [A1] FROM [dbo].[RoleMembership] AS [Extent2] WHERE [Extent1].[ID] = [Extent2].[MemberID]) AS [C1] FROM [dbo].[Members] AS [Extent1] ) AS [Project1] WHERE (100 = [Project1].[ID]) AND ([Project1].[C1] > 0) For brevity I turned the list of all the columns from the Members table into * As you can see it's just ignoring the "Role" query... :/
