  • 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

  • Need your feedback on our new SQL Server Connectivity portal

    - by The Official Microsoft IIS Site
    SQL Server, as a database product, has grown over the years and there are multiple ways to connect to it. Often, the different ways to connect to the database get documented and discussed in the various technology sections, and the technology choice determines which connectivity method one is going to use. For example, if one is writing a C++ application then one has to go with ODBC whereas a PHP web site developer will choose the PHP driver of course. Until now, this information was scattered all...(read more)

  • bug: deviation from requirements vs deviation from expectations

    - by user970696
    I am not clear on this one. No matter the terminology, in the end the software fault/bug causes (according to a lot of sources): Deviation from requirements Devation from expectations But if the expectations are not in requirements, then stakeholder could see a bug everywhere as he expected it to be like this or that..So how can I really know? I did read that specification can miss things and then of course its expected but not specified (by mistake).

  • 2011 - ALMs for your development team and the people they work with.

    - by David V. Corbin
    Welcome to 2011, it is already shaping up to be a very exciting year. The title of the post is not about charitable giving, although that is also a great topic. Application Lifecycle Management and the Systems that support the environment is, and 2011 will be a year where I expect many teams to invest heavily in this area. For those not familiar with ALM, it can be simplified down to "A comprehensive view of all of the iteas, requirements, activities and artifacts that impact an application over the course of its lifecycle, from concept until decommissioning". Obviously, this encompases a large number of different areas even for relatively small and medium sized projects. In recent years, many teams have adapted methodoligies which address individual aspects of this; but the majority of this adoption has resulted in "islands of improvement" rather than the desired comprehensive outcome...Until now! Last year Microsoft released Team Foundation Server 2010 along with Visual Studio 2010 Ultimate Edition, and with these two in combination the situation has drastically changed. At last there is a single environment that is capable of handling all aspects of ALM, and is also capable of dealing with migration and integration with existing systems to make the transition to a single solution much easier. Thse possibilities (and practicalities) are nothing short of amazing, Architecture thru Testing integration? YES. Being able to correlate specific requirement items (and their history) to actual code (and code history)? YES. Identification of which tests will be potentially impacted by a given code change? YES. Resiliant Automated Testing of User Interfaces? YES. Automatic Deployment Management? YES. Integraton Level testing as part of (designated) Builds? YES. I could easily double or triple the above list, but these items should be enough to get you thinking about the "pain points" your team and organization currently face and the fact that there IS a way to relieve the pain. Over the course of the year, I am hoping to bring together some of the "best of breed" information, along with hosting (and participating in) discussions with various experts in the field. There are already a number of groups (including many on LinkedIn) that have an ALM focus, and I encourage everyone out to check them out. I will be posting a list of the ones I find most helpful in the not too distant future. As I said at the beginning, 2011 is shaping up to be a very interesting (and productive) year. Why wait to start investigating and adopting ALM? ps: For those interested in becoming an "Alms Giver" in the charitable sense, I highly recommend checking out GiveCamp. A group of developers, designers and others get together to create a solution for a charity in just under 48 hours. I will be attending the GiveCamp in New York City on Jan 14-16, more information is available at nycgivecamp.org/

  • Teaching "web design/development" to high-school home-school group. Good sources?

    - by anonymous coward
    I may soon begin teaching a "web design and development" class for a home-school co-op group. Any suggestions for "course" material? My first thought was to work through the Opera Web Standards Curriculum, but am interested in hearing about possible alternatives or suggestions that better cover the "very basics" of getting started with designing and developing web pages. Not necessarily looking for topics, so much as existing resources. Thanks so much for your input!

  • Modify the number of entries in the list to choose from for bookmarking a site in Firefox

    I am wondering if it is possible to change the number of entries in the list which appears when in Firefox you right click on a tab and choose "add to bookmarks" Thats because I use to categorize a lot of bookmarks and the standard choice of 5 entries is too small. Of course the idea is to not have to click on "choose" further down following the menu Thanks in advance and this is a really fantastic Website for Ubuntu users cheers Roberto

  • Customer won't decide, how to deal?

    - by Crazy Eddie
    I write software that involves the use of measured quantities, many input by the user, most displayed, that are fed into calculation models to simulate various physical thing-a-majigs. We have created a data type that allows us to associate a numeric value with a unit, we call these "quantities" (big duh). Quantities and units are unique to dimension. You can't attach kilogram to a length for example. Math on quantities does automatic unit conversion to SI and the type is dimension safe (you can't assign a weight to a pressure for example). Custom UI components have been developed that display the value and its unit and/or allow the user to edit them. Dimensionless quantities, having no units, are a single, custom case implemented within the system. There's a set of related quantities such that our target audience apparently uses them interchangeably. The quantities are used in special units that embed the conversion factors for the related quantity dimensions...in other words, when using these units converting from one to another simply involves multiplying the value by 1 to the dimensional difference. However, conversion to/from the calculation system (SI) still involves these factors. One of these related quantities is a dimensionless one that represents a ratio. I simply can't get the "customer" to recognize the necessity of distinguishing these values and their use. They've picked one and want to use it everywhere, customizing the way we deal with it in special places. In this case they've picked one of the dimensions that has a unit...BUT, they don't want there to be a unit (GRR!!!). This of course is causing us to implement these special overrides for our UI elements and such. That of course is often times forgotten and worse...after a couple months everyone forgets why it was necessary and why we're using this dimensional value, calling it the wrong thing, and disabling the unit. I could just ignore the "customer" and implement the type as the dimensionless quantity, which makes most sense. However, that leaves the team responsible for figuring it out when they've given us a formula using one of the other quantities. We have to not only figure out that it's happening, we have to decide what to do. This isn't a trivial deal. The other option is just to say to hell with it, do it the customer's way, and let it waste continued time and effort because it's just downright confusing as hell. However, I can't count the amount of times someone has said, "Why is this being done this way, it makes no sense at all," and the team goes off the deep end trying to figure it out. What would you do? Currently I'm still attempting to convince them that even if they use terms interchangeably, we at the least can't do that within the product discussion. Don't have high hopes though.

  • PowerShell – Show a Notification Balloon

    - by BuckWoody
    In my presentations for PowerShell I sometimes want to start a process (like a backup) that will take some time. I normally pop up a notification “balloon” at the start, and then do the bulk of the work, and then pop up a balloon at the end to let me know it’s done. You can actually try out this little sample (on a test system, of course) without any other code to see what it does. Then just put the other PowerShell commands in the #Do Some Work part. Oh – throw an icon (.ico file) in a c:\temp directory or point that somewhere else. (No, this probably isn’t original. Can’t remember where I saw the original code, but I’ve modified it a bit anyway, so if you’re the original author and this looks slightly familiar, post a comment.) [void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") $objBalloon = New-Object System.Windows.Forms.NotifyIcon $objBalloon.Icon = "C:\temp\Folder.ico" # You can use the value Info, Warning, Error $objBalloon.BalloonTipIcon = "Info" # Put what you want to say here for the Start of the process $objBalloon.BalloonTipTitle = "Begin Title" $objBalloon.BalloonTipText = "Begin Message" $objBalloon.Visible = $True $objBalloon.ShowBalloonTip(10000) # Do some work # Put what you want to say here for the completion of the process $objBalloon.BalloonTipTitle = "End Title" $objBalloon.BalloonTipText = "End Message" $objBalloon.Visible = $True $objBalloon.ShowBalloonTip(10000) Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system.

    I'm planning to move a hard drive from one server machine to another. The hard drive is an IDE drive. The motherboards are different, as are the memory and such. In this instance, graphics isn't a problem because this is just Ubuntu Server. Are there any precautions I should take, or steps I can do beforehand, in order to make this go as smoothly as possible? I've of course already backed up /home directories and configurations in /etc and /var.
