• Windows8, JavaScript and HTML5 - A good thing?

  - by Albers

  Most of us have seen the Windows 8 news regarding support for native HTML5/JavaScript applications. The press has pushed this as a potential threat to the .NET developer community because JavaScript and HTML5 were called "our new developer platform". The press release refers to "Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.".Microsoft has also been hush on details related to these comments. Before we buy the hype and start worrying about a world where we drop our Visual Studio licenses and buy DreamWeaver - let's think about how Windows 8 HTML/JavaScript applications would be implemented. The HTML5 spec offers support for offline applications, but this won't offer the OS-integrated experience the press release refers to. MS has to be planning a way to extend access beyond the traditional JavaScript feature set. Microsoft has a similar option today: HTML Applications or HTAs. They come close to required features, but HTAs need ActiveX or Java integration to provide the promised OS-level access. I'm guessing that Microsoft's future OS strategy isn't built on developers cranking out ActiveX controls or Java applets. So where is Microsoft headed? One possibility is that MS builds a new JavaScript framework from the ground up outside their current APIs. Another idea would be for Microsoft to add support for JavaScript as a first class .NET language using the Dynamic Language Runtime. A solution based on the DLR could be integrated into an HTA-like model to provide the promised access, along with the full range of features in .NET Framework. Security comes included in the Framework. And the work necessary to support this integration would tie in nicely with the effort MS has recently made providing better JavaScript and HTML5 support in Visual Studio 2010. As a bonus, a full-fledged JavaScript DLR implementation would allow single language web solutions across client and server (think node.js) and would appeal to developers who are familiar with JavaScript but have less experience with the Microsoft tech stack. We will all get a better picture after the Build conference in September. But in the mean time we know that Microsoft has a reputation for providing strong developer support. We might want to reserve our harshest judgement and consider that the press release could hint at new opportunities for .NET development.

• Harnessing Business Events for Predictive Decision Making - part 1 / 3

  - by Sanjeev Sharma

  Businesses have long relied on data mining to elicit patterns and forecast future demand and supply trends. Improvements in computing hardware, specifically storage and compute capacity, have significantly enhanced the ability to store and analyze mountains of data in ever shrinking time-frames. Nevertheless, the reality is that data growth is outpacing storage capacity by a factor of two and computing power is still very much bounded by Moore's Law, doubling only every 18 months.Faced with this data explosion, businesses are exploring means to develop human brain-like capabilities in their decision systems (including BI and Analytics) to make sense of the data storm, in other words business events, in real-time and respond pro-actively rather than re-actively. It is more like having a little bit of the right information just a little bit before hand than having all of the right information after the fact. To appreciate this thought better let's first understand the workings of the human brain.Neuroscience research has revealed that the human brain is predictive in nature and that talent is nothing more than exceptional predictive ability. The cerebral-cortex, part of the human brain responsible for cognition, thought, language etc., comprises of five layers. The lowest layer in the hierarchy is responsible for sensory perception i.e. discrete, detail-oriented tasks whereas each of the above layers increasingly focused on assembling higher-order conceptual models. Information flows both up and down the layered memory hierarchy. This allows the conceptual mental-models to be refined over-time through experience and repetition. Secondly, and more importantly, the top-layers are able to prime the lower layers to anticipate certain events based on the existing mental-models thereby giving the brain a predictive ability. In a way the human brain develops a "memory of the future", some sort of an anticipatory thinking which let's it predict based on occurrence of events in real-time. A higher order of predictive ability stems from being able to recognize the lack of certain events. For instance, it is one thing to recognize the beats in a music track and another to detect beats that were missed, which involves a higher order predictive ability.Existing decision systems analyze historical data to identify patterns and use statistical forecasting techniques to drive planning. They are similar to the human-brain in that they employ business rules very much like mental-models to chunk and classify information. However unlike the human brain existing decision systems are unable to evolve these rules automatically (AI still best suited for highly specific tasks) and  predict the future based on real-time business events. Mistake me not,  existing decision systems remain vital to driving long-term and broader business planning. For instance, a telco will still rely on BI and Analytics software to plan promotions and optimize inventory but tap into business events enabled predictive insight to identify specifically which customers are likely to churn and engage with them pro-actively. In the next post, i will depict the technology components that enable businesses to harness real-time events and drive predictive decision making.

• TechEd 2012: Recap

  - by Tim Murphy

  TechEd this week was a great experience and I wanted to wrap it up with a summary post. First let me say a thank you to John and Jeff from GWB for supplying power, connectivity and a place to work in between sessions.  The blogging hub was a great experience in itself.  Getting to talk with other bloggers and other conference goers turned into a series of interesting conversations.  And where else can you almost end up in the day 1 highlights video? The sessions at TechEd were a mixed bag of value.  The Keynotes rocked, both figuratively and literally and most of the sessions that I want to were a good experience and had gems of information to take away.  There were a few exceptions though.  A couple of the sessions turned out to be sales jobs.  Nothing turns me off more than that (there will be some really honest comments on those surveys). TechEd re-enforced for me that much of the value is not in the sessions, but in the networking opportunities. I got to talk with several Microsoft team members and MVPs as well as some of the vendor representative for companies like Inrule and ComponentOne. Also got to expand both my local and extended community with discussions at meal times and waiting for sessions to start. I think this is one of the benefits that a lot of people don’t take advantage of in these conferences that should be a bigger part of the advertising. Exposure to a wide variety of topics, many of which I had not been able to make time for up to this point was envigorating.  The list of topic includes: Office 365, Windows Server 2012, Windows 8, Metro, Azure.  I can’t wait to get back to work and dig into these subjects in more depth. The one complaint that I had and heard from other attendees was that there weren’t enough sessions that were actually about development.  I realize that TechEd started as an event for IT Pros, but there needs to be more value for the Devs.  It all went by too fast and it will take a couple more days to digest the material, but the batteries are and I’m ready to leverage what I’ve learned.  Hopefully we will do it again next year. del.icio.us Tags: TechEd,TechEd 2012

• OpenWorld in Small Bites

  - by Kathryn Perry

  Fifty thousand attendees -- that's bigger than the cities some of us live in. Monday morning it took 20 minutes to get from Hall D in Moscone North to a conference room in Moscone South -- the crowds were crushing! A great start to a great week! Larry is as big a name as ever on the program schedule and on the Moscone stage. People were packed in Hall D and clustered around every big screen TV. He stayed on script as he laid out Oracle's SaaS, PaaS, and IaaS strategies. Every seat in Chris Leone's Fusion Apps Cloud Overview was filled on Monday morning. Oracle employees who wanted to get in were turned away. And the same thing happened in the repeat session on Wednesday. Our newest suite of apps is hot! Speaking of hot, the weather was made to order. Then it turned very San Francisco-like on Wednesday afternoon. Downright cold for those who trusted SF temps to hold in the 80's. Who did you follow on Twitter during the conference? So many voices, opinions, and convos! Great combo of social media and sharp minds. Be sure to follow @larryellison, @stevenrmiranda, and @Oracle for updates and MyPOVs. Keywords for the Apps customers at the conference were cloud, mobile, and social. Every day, every session, every speaker. Wednesday afternoon, 4 pm at the Four Seasons hotel. A large roomful of analysts and influencers firing questions at a panel of eight Fusion customers. Steve Miranda moderating. Good energy and a great exchange of information and confidence. Word on the street is that OpenWorld has outgrown San Francisco -- but moving it seems unthinkable. The city isn't just a backdrop for an industry conference - it's a headliner right up there with Larry Ellison and Pearl Jam. As you can imagine, electrical outlets were in high demand at every venue. The most popular hotels and bars near Moscone designed their interiors around accessible electrical power strips. People are plenty willing to buy a drink while they grab a charge. Wednesday afternoon, 4 pm at the Four Seasons hotel. A large roomful of analysts and influencers firing questions at a panel of eight Fusion customers. Steve Miranda moderating. Good energy and a great exchange of information and confidence. Treasure Island in the dark. Eddy Vedder has an amazing voice! And Kings of Leon over delivered on people's expectations. It was cold. It was windy. It was very fun. One analyst said it's the best customer appreciation party in the industry.

• The Buzz at the JavaOne Bookstore

  - by Janice J. Heiss

  I found my way to the JavaOne bookstore, a hub of activity. Who says brick and mortar bookstores are dead? I asked what was hot and got two answers: Hadoop in Practice by Alex Holmes was doing well. And Scala for the Impatient by noted Java Champion Cay Horstmann also seemed to be a fast seller. Hadoop in PracticeHadoop is a framework that organizes large clusters of computers around a problem. It is touted as especially effective for large amounts of data, and is use such companies as  Facebook, Yahoo, Apple, eBay and LinkedIn. Hadoop in Practice collects nearly 100 Hadoop examples and presents them in a problem/solution format with step by step explanations of solutions and designs. It’s very much a participatory book intended to make developers more at home with Hadoop.The author, Alex Holmes, is a senior software engineer with more than 15 years of experience developing large-scale distributed Java systems. For the last four years, he has gained expertise in Hadoop solving Big Data problems across a number of projects. He has presented at JavaOne and Jazoon and is currently a technical lead at VeriSign.At this year’s JavaOne, he is presenting a session with VeriSign colleague, Karthik Shyamsunder called “Java: A Perfect Platform for Data Science” where they will explain how the Java platform has emerged as a perfect platform for practicing data science, and also talk about such technologies as Hadoop, Hive, Pig, HBase, Cassandra, and Mahout. Scala for the ImpatientSan Jose State University computer science professor and Java Champion Cay Horstmann is the principal author of the highly regarded Core Java. Scala for the Impatient is a basic, practical introduction to Scala for experienced programmers. Horstmann has a presentation summarizing the themes of his book on at his website. On the final page he offers an enticing summary of his conclusions:* Widespread dissatisfaction with Java + XML + IDEs               --Don't make me eat Elephant again * A separate language for every problem domain is not efficient               --It takes time to master the idioms* ”JavaScript Everywhere” isn't going to scale* Trend is towards languages with more expressive power, less boilerplate* Will Scala be the “one ring to rule them”?* Maybe              --If it succeeds in industry             --If student-friendly subsets and tools are created The popularity of both books echoed comments by IBM Distinguished Engineer Jason McGee who closed his part of the Sunday JavaOne keynote by pointing out that the use of Java in complex applications is increasingly being augmented by a host of other languages with strong communities around them – JavaScript, JRuby, Scala, Python and so forth. Java developers increasingly must know the strengths and weaknesses of such languages going forward.

• As a tooling/automation developer, can I be making better use of OOP?

  - by Tom Pickles

  My time as a developer (~8 yrs) has been spent creating tooling/automation of one sort or another. The tools I develop usually interface with one or more API's. These API's could be win32, WMI, VMWare, a help-desk application, LDAP, you get the picture. The apps I develop could be just to pull back data and store/report. It could be to provision groups of VM's to create live like mock environments, update a trouble ticket etc. I've been developing in .Net and I'm currently reading into design patterns and trying to think about how I can improve my skills to make better use of and increase my understanding of OOP. For example, I've never used an interface of my own making in anger (which is probably not a good thing), because I honestly cannot identify where using one would benefit later on when modifying my code. My classes are usually very specific and I don't create similar classes with similar properties/methods which could use a common interface (like perhaps a car dealership or shop application might). I generally use an n-tier approach to my apps, having a presentation layer, a business logic/manager layer which interfaces with layer(s) that make calls to the API's I'm working with. My business entities are always just method-less container objects, which I populate with data and pass back and forth between my API interfacing layer using static methods to proxy/validate between the front and the back end. My code by nature of my work, has few common components, at least from what I can see. So I'm struggling to see how I can better make use of OOP design and perhaps reusable patterns. Am I right to be concerned that I could be being smarter about how I work, or is what I'm doing now right for my line of work? Or, am I missing something fundamental in OOP? EDIT: Here is some basic code to show how my mgr and api facing layers work. I use static classes as they do not persist any data, only facilitate moving it between layers. public static class MgrClass { public static bool PowerOnVM(string VMName) { // Perform logic to validate or apply biz logic // call APIClass to do the work return APIClass.PowerOnVM(VMName); } } public static class APIClass { public static bool PowerOnVM(string VMName) { // Calls to 3rd party API to power on a virtual machine // returns true or false if was successful for example } }

• TechEd 2012: Windows 8 And Metro

  - by Tim Murphy

  Windows 8 is here (or at least very close) and that was the main feature of this morning’s key note.  Antoine LeBlond started off by apologizing to the IT professionals since he planned on showing code.  I’m not sure if IT Pros are that easily confused or why you would need such a disclaimer.  Developers do real work, IT Pros just play with toys (just kidding). The highlights of the Windows 8 keynote for me started with some of the UI design elements that I had not seen when I was shown one of the Build tablets.  Specifically I liked the AppBar features that we have become used to with Windows Phone and some of the gesture features.  Even though they have been available on other platforms before I think Microsoft really got them right. Two other great features of Windows 8 that they demonstrated were the Hyper-V capabilities and the ability to run Windows 8 anywhere from a USB key.  My jaw dropped through the floor seeing a feature rich OS boot off of a thumb drive. WOW!  I also can’t wait to get rid of dual booting just to run Hyper-V images when developing. The morning continued with a session on Metro XAML development with Tim Heuer.  While included a lot of great XAML Metro demos, I was pleasantly surprised by some of the things I found out about Visual Studio 2012.  Finding out that Blend is now integrated with VS2012 was a nice addition after working with them as separate applications was an encouraging start. Moving on to Metro he introduced the nugget that WinRT is Async everywhere.  How deep this model goes will be an interesting thing to find out as I learn more about developing for the platform.  Thankfully he followed that up with a couple of new keywords, await and async, that eliminates a lot of plumbing that has been required in the past for asynchronous transactions. Tim also related that since the Metro framework is relatively small and most apps will use a significant amount of it the entire surface is referenced by default.  This is a contrast to adding namespace and assemblies one after another as we normally do. This was such a power packed session that I can’t detail it all here so here is the teaser list. New icons in VS2012 for extension methods Emulator/simulator testing features for gestures Portable class libraries XAML no longer managed code And so much more …   del.icio.us Tags: Windows 8,Metro,Tim Heuer,XAML,Widows Phone,Hyper-V,Antoine LeBlond,TechEd,TechEd 2012,Visual Studio 2012,Visual Studio

• 50 Billion Served: Java Embedded on Devices

  - by Tori Wieldt

  It doesn't matter if it is 50 billion or 24 billion, just suffice it to stay that there will be MANY connected devices in the year 2020. With just 24 billion devices, they will outnumber humans six to one! So as a developer, you don't want to ignore this opportunity. What if you could use your Java skills and deploy an app to a fraction of these devices (don't be greedy, how about just, say, 118,000 of them)? Fareed Suliman, Java ME Product Manager had lots of good news for Java Developers in his presentation Modernizing the Explosion of Advanced Microcontrollers with Embedded Java at ARM TechCon in Santa Clara, CA last week. "A radical architecture shift is underway in this space, from proprietary to standards-based," he explained.  He pointed out several advantages to using Embedded Java for devices: Java is a proven and open standard. Java provides connectivity, encryption, location, and web services APIs. You don't have to focus on and keep reinventing the plumbing below the JVM. Abstracting the software from the hardware allows you to repeat your app across many devices. Abstracting the software from the hardware allows allows parallel development so you can get your app done more quickly. You already know Java (or you can hire lots of Java talent). Java is a full ecosystem, with Java Embedded plugins for IDEs like Eclipse and NetBeans. Java ME allows for in-field software upgrades. Suliman mentioned two ways developers can start using Java Embedded today:  Java ME Embedded Suite 7.0 Oracle Java Embedded Suite is a new packaged solution from Oracle (including Java DB, GlassFish for Embedded Suite, Jersey Web Services Framework, and Oracle Java SE Embedded 7 platform), created to provide value added services for collecting, managing, and transmitting data to embedded devices such as gateways and concentrators. Oracle Java ME Embedded 3.2 Oracle Java ME Embedded 3.2 is designed and optimized to meet the unique requirements of small embedded, low power devices such as micro-controllers and other resource-constrained hardware without screens or user interfaces. Think tiny. Really tiny. And think big.  Read more about Java Embedded at the Oracle Technology Network, and read The Java Source blog Java Embedded Releases from September.

• Windows 8 and the future of Silverlight

  - by Laila

  After Steve Ballmer's indiscrete 'MisSpeak' about Windows 8, there has been a lot of speculation about the new operating system. We've now had a few glimpses, such as the demonstration of 'Mosh' at the D9 2011 conference, and the Youtube video, which showed a touch-centric new interface for apps built using HTML5 and JavaScript. This has caused acute anxiety to the programmers who have followed the recommended route of WPF, Silverlight and .NET, but it need not have caused quite so much panic since it was, in fact, just a thin layer to make Windows into an apparently mobile-friendly OS. More worryingly, the press-release from Microsoft was at pains to say that 'Windows 8 apps use the power of HTML5, tapping into the native capabilities of Windows using standard JavaScript and HTML', as if all thought of Silverlight, dominant in WP7, had been jettisoned. Ironically, this brave new 'happening' platform can all be done now in Windows 7 and an iPad, using Adobe Air, so it is hardly cutting-edge; in fact the tile interface had a sort of Retro-Zune Metro UI feel first seen in Media Centre, followed by Windows Phone 7, with any originality leached out of it by the corporate decision-making process. It was kinda weird seeing old Excel running alongside stodgily away amongst all the extreme paragliding videos. The ability to snap and resize concurrent apps might be a novelty on a tablet, but it is hardly so on a PC. It was at that moment that it struck me that here was a spreadsheet application that hadn't even made the leap to the .NET platform. Windows was once again trying to be all things to all men, whereas Apple had carefully separated Mac OS X development from iOS. The acrobatic feat of straddling all mobile and desktop devices with one OS is looking increasingly implausible. There is a world of difference between an operating system that facilitates business procedures and a one that drives a device for playing pop videos and your holiday photos. So where does this leave Silverlight? Pretty much where it was. Windows 8 will support it, and it will continue to be developed, but if these press-releases reflect the thinking within Microsoft, it is no longer seen as the strategic direction. However, Silverlight is still there and there will be a whole new set of developer APIs for building touch-centric apps. Jupiter, for example, is rumoured to involve an App store that provides new, Silverlight based "immersive" applications that are deployed as AppX packages. When the smoke clears, one suspects that the Javascript/HTML5 is merely an alternative development environment for Windows 8 to attract the legions of independent developers outside the .NET culture who are unlikely to ever take a shine to a more serious development environment such as WPF or Silverlight. Cheers, Laila

• Facebook Game database design

  - by facebook-100000781341887

  Hi, I'm currently develop a facebook mafia like PHP game(of course, a light weight version), here is a simplify database(MySQL) of the game id-a <int3> <for index> uid <chr15> <facebook uid> HP <int3> <health point> exp <int3> <experience> money <int3> <money> list_inventory <chr5> <the inventory user hold...some special here, talk next> ... and 20 other fields just like reputation, num of combat... *the number next to the type is the size(byte) of the type For the list_inventory, there have 40 inventorys in my game, (actually, I have 5 these kind of list in my database), and each user can only contain 1 qty of each inventory, therefore, I assign 5 char for this field and each bit of char as 1 item(5 char * 8 bit = 40 slot), and I will do some manipulation by PHP to extract the data from this 5 byte. OK, I was thinking on this, if this game contains 100,000 user, and only 10% are active, therefore, if use my method, for the space use, 5 byte * 100,000 = 500 KB if I use another method, create a table user_hold_inventory, if the user have the inventory, then insert a record into this table, so, for 10,000 active user, I assume they got all item, but for other, I assume they got no item, here is the fields of the new table id-b <int3> <for index> id-a <int3> <id of the user table> inv_no <int1> <inventory that user hold> for the space use, ([id] (3+3) byte + [inv_no] 1 byte ) * [active user] 10,000 * [all inventory] * 40 = 2.8 MB seems method 2 have use more space, but it consume less CPU power. Please comment these 2 method or please correct me if there have another better method rather than what I think. Another question is, my database contain 26 fields, but I counted 5 of them are not change frquently, should I need to separate it on the other table or not? So many words, thanks for reading :)

• Driving Growth through Smarter Selling

  - by Samantha.Y. Ma

  With the proliferation of social media and mobile technologies, the world of selling and buying has drastically changed, as buyers now have access to more information than they did in the past. In fact, studies have shown that buyers complete 60 percent of the buying process before they even engage with a salesperson. The old models of selling no longer work effectively; and the new way of selling is driven by customer insights. To succeed, sales need to be proactive, not reactive. They need to engage with the customer early, sometimes even before the customer’s needs are fully understood. In fact, the best sales reps prescribe a solution that the customer doesn't even know they need, often by leveraging social media to listen, engage and collaborate with peers. And they fully tap into the power of analytics and data to drive results.  Let’s look at some stats regarding challenges facing sales today. According to recent studies, sales reps spend 78 percent of their time doing administrative things -- such as planning, searching for information, data entry -- and only 22 percent of the time actually selling. Furthermore, 40 percent of B2B sales reps miss their quota, and only 3 percent of companies can say with confidence that their forecasts are “always accurate.” How do you drive growth in this modern day and age? It's not just getting your sales teams to work harder; it's helping them work smarter and providing them with a solution they want to use, on the device(s) they already know, giving them critical insights and tools to be more productive, increase win rates, and close deals faster. Oracle Sales Cloud was designed to do exactly that. It enables smarter selling that allows reps to sell more, managers to know more, and companies to grow more.  Let’s face it—if all CRM solutions worked well, sales executives wouldn’t be having the same headaches as they had in the past. Join Oracle’s Thomas Kurian and Doug Clemmans on Tuesday, October 22 as they explain: • How today’s sales processes have rendered many CRM systems obsolete • The secrets to smarter selling, leveraging mobile, social, and big data • How Oracle Sales Cloud enables smarter selling—as proven by Oracle and its customers Take the first step down the path toward smarter selling. With Oracle Sales Cloud, reps sell more, managers know more, and companies grow more.

• SharePoint Thoughts

  - by Tim Murphy

  I was listening to .NET Rocks episode #713 and it got me thinking about a number of SharePoint related topics. I have been working with SharePoint since the 2001 product came out and have watched it evolve over the years.  Today SharePoint is one of the most powerful and flexible products in the market.  Of course that doesn’t mean there isn’t room for improvement (a lot of improvement in fact) and with much power comes much responsibility. My main gripe these days is that you have to develop on a server instance.  This adds a real barrier to entry for developers.  You either have to run VMWare or Hyper-V on your developer machine or actually develop on your dev server for most tasks.  Yes, there is a way to setup a Windows 7 machine with the SharePoint components but it is very hackish. Beyond that the tools in VS2010 are a great leap forward from past generations.  Not requiring a separate package creation tool is not the least of the improvements.  Better workflow and web part development have also eased the burden of many developers. The other thing the show brought up in my thoughts was more around usage.  Users want to be able to self server everything without regard to what affect that has on leveraging their data from a corporate perspective.  My coworkers who work on Lotus Notes ask why the user can’t just do what ever they want? Part of the reason is that those features have not been built, but the other part is that giving them those features is often like giving an infant a loaded hand gun.  You can do it but it doesn’t make it the smart thing to do. As with any tool that is going to be used in the enterprise it should be subject to governance.  If controls are not in place as they said in the episode of DNR the document libraries and I believe SharePoint in general starts to look as disarrayed and unusable as a shared drive.  Consider these factors before giving into every whim of the users.  You should be able to explain to them the tradeoffs of giving them full control versus being able to leverage the information they collect to the benefit of the organization. These are just a couple of the thoughts that were triggered by the show.  I’m sure there are more discussions that can be had.  Feel free to leave your comments about the pros and cons of SharePoint. del.icio.us Tags: .NET Rocks,SharePoint,software development

• USB Drive Warm Boot Issue. Cold boot = Perfect. Warm boot = "No boot sector found on USB device"

  - by Dan

  I'm experiencing a boot/reboot quirk similar to, yet somewhat different from others posted here. I have two Western Digital "Passport" external USB2 drives (160GB and 320GB) with Ubuntu 11.10 installed. The BIOS on my laptop is set to boot USB drives before the internal drive, and it works well. Either drive will cold-boot Ubuntu 11.10 perfectly. However, at times the computer must be restarted (warm boot) to have software updates or other changes take effect. When I warm-boot the computer, the computer goes through its normal shutdown/restart, then the usual BIOS tests, at which time the USB drive is selected momentarily (as normal), and that's when the trouble starts. I get a "No boot sector found on USB device", and the computer proceeds to boot Windows from the internal drive. If I press F12 early during the restart sequence (allows manual selection of the boot sequence), USB is still shown before the internal drive on the sequence list (as it should be). If I highlight "USB" and press ENTER, I still get a "No boot sector..." error message, but the external USB drive then proceeds to boot Ubuntu normally. I have a third external USB drive (Western Digital 160 GB Media Center) that cold-boots and warm-boots perfectly, so I know everything in the computer is set up properly. It also tells me Ubuntu is set up correctly on the drives, as all three drives were done identically, and at the same time. I've tried formatting the Passport drives NTFS and FAT32, but it didn't change anything. If I power-down the computer, then start it up again, it will boot Ubuntu from either of the Passport drives perfectly - every time. It's as if during a warm boot the Passport drives are somehow looking for the boot loader in the wrong location on the drive - yet either drives works when booting from a cold start. Not a show-stopper .. but frustrating. Computer is a Dell XPS M1530, A12 BIOS (latest), but I don't think the computer plays into the issue because one of the three drives works at all times. It's only the two WD Passport models at issue here. Thanks!

• Hadoop, NOSQL, and the Relational Model

  - by Phil Factor

  (Guest Editorial for the IT Pro/SysAdmin Newsletter)Whereas Relational Databases fit the world of commerce like a glove, it is useless to pretend that they are a perfect fit for all human endeavours. Although, with SQL Server, we’ve made great strides with indexing text, in processing spatial data and processing markup, there is still a problem in dealing efficiently with large volumes of ephemeral semi-structured data. Key-value stores such as Cassandra, Project Voldemort, and Riak are of great value for ephemeral data, and seem of equal value as a data-feed that provides aggregations to an RDBMS. However, the Document databases such as MongoDB and CouchDB are ideal for semi-structured data for which no fixed schema exists; analytics and logging are obvious examples. NoSQL products, such as MongoDB, tackle the semi-structured data problem with panache. MongoDB is designed with a simple document-oriented data model that scales horizontally across multiple servers. It doesn’t impose a schema, and relies on the application to enforce the data structure. This is another take on the old ‘EAV’ problem (where you don’t know in advance all the attributes of a particular entity) It uses a clever replica set design that allows automatic failover, and uses journaling for data durability. It allows indexing and ad-hoc querying. However, for SQL Server users, the obvious choice for handling semi-structured data is Apache Hadoop. There will soon be an ODBC Driver for Apache Hive .and an Add-in for Excel. Additionally, there are now two Hadoop-based connectors for SQL Server; the Apache Hadoop connector for SQL Server 2008 R2, and the SQL Server Parallel Data Warehouse (PDW) connector. We can connect to Hadoop process the semi-structured data and then store it in SQL Server. For one steeped in the culture of Relational SQL Databases, I might be expected to throw up my hands in the air in a gesture of contempt for a technology that was, judging by the overblown journalism on the subject, about to make my own profession as archaic as the Saggar makers bottom knocker (a potter’s assistant who helped the saggar maker to make the bottom of the saggar by placing clay in a metal hoop and bashing it). However, on the contrary, I find that I'm delighted with the advances made by the NoSQL databases in the past few years. Having the flow of ideas from the NoSQL providers will knock any trace of complacency out of the providers of Relational Databases and inspire them into back-fitting some features, such as horizontal scaling, with sharding and automatic failover into SQL-based RDBMSs. It will do the breed a power of good to benefit from all this lateral thinking.

• Enum types, FlagAttribute & Zero value

  - by nmgomes

  We all know about Enums types and use them every single day. What is not that often used is to decorate the Enum type with the FlagsAttribute. When an Enum type has the FlagsAttribute we can assign multiple values to it and thus combine multiple information into a single enum. The enum values should be a power of two so that a bit set is achieved. Here is a typical Enum type: public enum OperationMode { /// <summary> /// No operation mode /// </summary> None = 0, /// <summary> /// Standard operation mode /// </summary> Standard = 1, /// <summary> /// Accept bubble requests mode /// </summary> Parent = 2 } In such scenario no values combination are possible. In the following scenario a default operation mode exists and combination is used: [Flags] public enum OperationMode { /// <summary> /// Asynchronous operation mode /// </summary> Async = 0, /// <summary> /// Synchronous operation mode /// </summary> Sync = 1, /// <summary> /// Accept bubble requests mode /// </summary> Parent = 2 } Now, it’s possible to do statements like: [DefaultValue(OperationMode.Async)] [TypeConverter(typeof(EnumConverter))] public OperationMode Mode { get; set; } /// <summary> /// Gets a value indicating whether this instance supports request from childrens. /// </summary> public bool IsParent { get { return (this.Mode & OperationMode.Parent) == OperationMode.Parent; } } or switch (this.Mode) { case OperationMode.Sync | OperationMode.Parent: Console.WriteLine("Sync,Parent"); break;[…]  But there is something that you should never forget: Zero is the absorber element for the bitwise AND operation. So, checking for OperationMode.Async (the Zero value) mode just like the OperationMode.Parent mode makes no sense since it will always be true: (this.Mode & 0x0) == 0x0 Instead, inverse logic should be used: OperationMode.Async = !OperationMode.Sync public bool IsAsync { get { return (this.Mode & ContentManagerOperationMode.Sync) != ContentManagerOperationMode.Sync; } } or public bool IsAsync { get { return (int)this.Mode == 0; } } Final Note: Benefits Allow multiple values combination The above samples snippets were taken from an ASP.NET control and enabled the following markup usage: <my:Control runat="server" Mode="Sync,Parent"> Drawback Zero value is the absorber element for the bitwise AND operation Be very carefully when evaluating the Zero value, either evaluate the enum value as an integer or use inverse logic.

• Writing or extending existing emacs packages: is it worth or should I move to Netbeans/Eclipse?

  - by Andrea

  I'm finishing my master degree course in CS and I've almost become addicted to Emacs. I've used it to write in C, Latex, Java, JSP,XML, CommonLisp, Ada and other languages no other editor supported, like AMPL. I'd like to improve the packages I've been using the most or create new ones, but, in practice, I find that the implementation of Emacs leaves a lot to be desired. There are a lot of poorly-featured/poorly-maintained packages with either overlapping functionalities or obscure incompatibilities, and Elisp just seems to foster the situation by lacking the common features modern lisps have. In contrast Eclipse and Netbeans are actively improved and it does seem they can be effective for non-mainstream languages. I tried Hibachi for Ada in Eclipse and it worked well, there's CUPS for Lisp in Eclipse and LambdaBeans built using NetBeans components. On the other hand those plugins seem to be less active than their Emacs' counterparts, for example Hibachi was archived last year. What's your opinion on this? Which editor should I write extension for? EDIT: To answer Larry Coleman (see comment below): I like Emacs as a user because it is efficient both for me and the computer I'm using. It's fast and the textual interface (i.e. minibuffer) allows for quick interaction. It's solid and packages are usually small and easy to manage. If I need to correct or remove something I usually just have to change a row in my .emacs or an elisp file, or delete a directory. Eclipse plugins rely on a more complicated process that screwed my Eclipse configuration a couple of times, forcing me to do a clean reinstall. Emacs works as long as I use the basic packages. If I need something more complicated the situation gets pretty hairy. As a "power user" I think that the best I can hope for is to write a severely crippled version of the extensions I'd actually like to have; in other words, that it's not worth the trouble. I'd like to write extensions for the things I'd like to have automated in Emacs, for example project support with automated tag-table update on file writing. There are a few projects on this that lack integration, documentation, extensibility and so forth. The best one is probably CEDET, for which I believe the Greenspun's 10th rule can be applied. EDIT: To comment Larry Coleman's answer I'm pretty sure I can pick elisp programming but the extensions I have in mind don't exist yet despite their relative simplicity and the effort more knowledgeable people poured into related projects.This makes me wonder whether it is so because of the way emacs is developed, i.e. people tend to write their own little extensions without coordination, or its implementation, its extension language not being able to keep up with the growing complexity.

• Looking for an ultra portable laptop for Ubuntu

  - by prule

  Hi, I'm in the market for a new laptop, and portability is important since I really only use it when I'm travelling to and from work - primarily for programming. I've been searching high and low for something like this: less than 2kg hopefully Intel i5 (but negotiable) NO dvd drive - just don't need it 4G ram either 7200rpm disk or SSD (ssd preferable) 13 inch screen not too pricey (MacBook Air is about $1700 AUD) available in Australia The Dell Inspiron 13z and Lenovo Edge 13 look close, but I've not found anything that says I'm not going to have a fight with compatibility. The MacBook Air 13 looks like the PERFECT hardware, but I'm afraid it will just be easier to run MacOS than Ubuntu. I want to stay with Ubuntu, but the MacBook Air is only $1700 so I'm in danger of becoming another apple fanboi if I can't find anything competitive. Going through all the sites looking for stuff has been a huge waste of time System 76 doesn't deliver to Australia http://www.linux-laptop.net/ and http://www.linlap.com/ are hard work and not confidence inspiring http://www.vgcomputing.com.au/nsintro.html is hard work again, searching for every laptop they say has excellent compatibility on the web to find out what spec it is http://zareason.com/shop/Strata-Pro-13.html (at $1345 USD) looks interesting, but I've got no idea how much I'll get stung by customs importing Dell Inspiron 13z with i5, 4G, 320 7200rpm disk, ATI Mobility Radeon HD5430 - 1GB, Dell Wireless 1501 802.11b/g/n @ $1200 AUD seems like the only competitor but is it compatible? (Dell support offer no opinion - as far as they are concerned they only have 2 models that are certified for ubuntu) Am I worrying too much about the compatibility? Should I just go with Dell? Or switch to MacOS? (It would be good to have a searchable database that had the full machine specs, and compatibility - I'm thinking about building something... but I don't have much time right now...) Thanks. UPDATE I went with a MacBook Air. The price/weight/power was just right. Everything else was either too pricy (i5) or too heavy, or underpowered (SU7300 1.3GHz). Its a pity, because I didn't really want to leave Ubuntu. I'll still run it on my media center and spare (heavy) laptop.

• Seven Accounting Changes for 2010

  - by Theresa Hickman

  I read a very interesting article called Seven Accounting Changes That Will Affect Your 2010 Annual Report from SmartPros that nicely summarized how 2010 annual financial statements will be impacted.  Here’s a Reader’s Digest version of the changes: 1.  Changes to revenue recognition if you sell bundled products with multiple deliverables: Old Rule: You needed to objectively establish the “fair value” of each bundled item. So if you sold a dishwasher plus installation and could not establish the fair value of the installation, you might have to delay recognizing revenue of the dishwasher days or weeks later until it was installed. New Rule (ASU 2009-13): “Objective” proof of each service or good is no longer required; you can simply estimate the selling price of the installation and warranty. So the dishwasher vendor can recognize the dishwasher revenue immediately at the point of sale without waiting a few weeks for the installation. Then they can recognize the estimated value of the installation after it is complete. 2.  Changes to revenue recognition for devices with embedded software: Old Rule: Hardware devices with embedded software, such as the iPhone, had to follow stringent software revrec rules. This forced Apple to recognize iPhone revenues over two years, the period of time that software updates were provided. New Rule (ASU 2009-14): Software revrec rules no longer apply to these devices with embedded software; these devices can now follow ASU 2009-13. This allows vendors, such as Apple, to recognize revenue sooner. 3.  Fair value disclosures: Companies (both public and private) now need to spend extra time gathering, summarizing, and disclosing information about items measured at fair value, such as significant transfers in and out of Level 1(quoted market price), Level 2 (valuation based on observable markets), and Level 3 (valuations based on internal information). 4.  Consolidation of variable interest entities (a.k.a special purpose entities): Consolidation rules for variable interest entities now require a qualitative, not quantitative, analysis to determine the primary beneficiary. Instead of simply looking at the percentage of voting interests, the primary beneficiary could have less than the majority interests as long as it has the power to direct the activities and absorb any losses.  5.  XBRL: Starting in June 2011, all U.S. public companies are required to file financial statements to the SEC using XBRL. Note: Oracle supports XBRL reporting. 6.  Non-GAAP financial disclosures: Companies that report non-GAAP measures of performance, such as EBITDA in SEC filings, have more flexibility.  The new interpretations can be found here: http://www.sec.gov/divisions/corpfin/guidance/nongaapinterp.htm.  7.  Loss contingencies disclosures: Companies should expect additional scrutiny of their loss disclosures, such as those from litigation losses, in their annual financial statements. The SEC wants more disclosures about loss contingencies sooner instead of after the cases are settled.

• Lenovo Thinkpad X1 Carbon support

  - by Robottinosino

  I am considering selling my Mac to get money towards a Lenovo Thinkpad X1 because what I really want to do is to be running an Ubuntu system all the time. Is this machine completely supported in Ubuntu, with no tiny little feature missing just because I am "going Linux"? Optional user story section, skip to the question below if you don't have time: I have a friend who bought a "works on Ubuntu" system a year ago and has hated the fact ever since: battery lasts less than if he boots in Windows (which he despises) and he ascribes that to "no good OS/harware integration and support for advanced chipset power management features", odd behaviour on suspend/resume/hibernate (says: "when it works 90% of the time and the other 10% it makes you lose your work is as good as broken - 90% is the same as 0% he says), some occasional graphics card glitches he can perfectly well live with and has almost grown affectionate to, and finally, and that is what would make him undo his choice if he could, bad "input device drivers". He says: trackpoint and trackpad just "feel different", "so much better" on Windows and that was impossible to know from the website brochure. That story makes me very doubtful... but I want to abandon this "walled garden" of prison that is my Mac and go Ubuntu all the way, no doubt about that! My dilemma at this time is just: "I don't want to live with those eternal frustrations for sure"! Here's a directly answerable phrasing of my question: Is the Lenovo Thinkpad X1 supported on Ubuntu? Yes/no, which version? Which hardware features are not supported? Provide a list Optionally: sort the list in descending order of frustration from your experience Optionally: mention if there are acceptable workarounds to the "out-of-the-box" condition described in the earlier points and whether this ameliorates frustration at least to "tolerable" levels Comment: the Ubuntu hardware certification page is so not-for-end-users it's unreal. Whoa. What would make it end-user friendly is: Link to "buy here and you'll be just fine, this is the right configuration for you, it'll work as long as you press BUY on that page and don't browse further" Remove mentions of may and might not work. Just tell it straight: press buy here and you will get a working system with the exception of A, B, C (so that I can decide whether the philosophical "freedom pleasure" I get from escaping an Apple world is enough to off-balance the loss, for instance, of Bluetooth capabilities (something that I of course use on my Mac) but "could" lose to use free (as in freedom) software The certification page fails to dispel doubts in me as an end-user. I don't feel "eased into Ubuntu", I feel "partially informed".

• Unable to ping inside or outside network with default gateway 0.0.0.0

  - by agentroadkill

  I've been around here before and I could usually piece together everything to more or less get myself up and running, but this time I'm truly stumped. I'm trying to connect my new 14.04 install to a network, and I'm forced to be behind my college's router. Now I've tested the vary cable that is right now plugged into my Ubuntu box on a Windows, Mac OS X, and even my friend's Ubuntu 14.04 box, and they all connect no problem. I've been trying to track this down for about two days, but every time I get close to it, the bug jumps to some other piece of my connection. Anyway, as it sits ifconfig -a gives: eth2 Lninkencap:Ethernet HWaddr:00:1f:bc:08:31:1d inet addr:10.32.51.51 Bcast:10.32.51.155 Mask: 255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 RX bytes:0 TX bytes:0 as well as the local loopback, but I'm assuming that is not an issue here. sudo dhclient -v eth2 returns: Listening on LPF/<hardware address of my integrated NIC, above> Sending on <same> Sending on Socket/fallback DHCPREQUEST of 10.32.51.51 on eth2 to 255.255.255.255 port 67 (xid=0x6f4a66ba) <two more lines of same> DHCPDISCOVER on eth2 to 255.255.255.255 port 67 interval 3 (xid=0x156f9fb4) <many more of above with varying intervals> No DHCPOFFERS received.

I've tried commenting out the "option rfc3442" line in /etc/dhcp/dhclient.conf which seemed to fix this issue for many people, as well as adding the line send vendor-class-indentifier "MSFT5.0" to dhclient.conf as well to tell the router I'm a windows box, in case they don't like Linux. Finally, route -n reveals: Destination Gateway Genmask Flags Metric Ref Use Iface 10.32.51.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 I would like to apologize in advance for the doubtless butchered text alignment, but I'm obviously typing this all by hand, reading from the terminal as I type commands. I'm hoping this is an interesting problem, and not something I blithely stumbled past in my (apparent) over-confidence. TIA! Quick addendum before posting: The activity light on the ethernet port are lit and one blinks during boot, but they rarely (and seemingly randomly) do so afterwards (both are dark) even while running dhclient in the foreground. When I had the Ubuntu box tethered to my MacBook earlier, I got what looked like a normal power/uplink blinking pattern, but was unable to ping one from the other.

• SQL 2014 does data the way developers want

  - by Rob Farley

  A post I’ve been meaning to write for a while, good that it fits with this month’s T-SQL Tuesday, hosted by Joey D’Antoni (@jdanton) Ever since I got into databases, I’ve been a fan. I studied Pure Maths at university (as well as Computer Science), and am very comfortable with Set Theory, which undergirds relational database concepts. But I’ve also spent a long time as a developer, and appreciate that that databases don’t exactly fit within the stuff I learned in my first year of uni, particularly the “Algorithms and Data Structures” subject, in which we studied concepts like linked lists. Writing in languages like C, we used pointers to quickly move around data, without a database in sight. Of course, if we had a power failure all this data was lost, as it was only persisted in RAM. Perhaps it’s why I’m a fan of database internals, of indexes, latches, execution plans, and so on – the developer in me wants to be reassured that we’re getting to the data as efficiently as possible. Back when SQL Server 2005 was approaching, one of the big stories was around CLR. Many were saying that T-SQL stored procedures would be a thing of the past because we now had CLR, and that obviously going to be much faster than using the abstracted T-SQL. Around the same time, we were seeing technologies like Linq-to-SQL produce poor T-SQL equivalents, and developers had had a gutful. They wanted to move away from T-SQL, having lost trust in it. I was never one of those developers, because I’d looked under the covers and knew that despite being abstracted, T-SQL was still a good way of getting to data. It worked for me, appealing to both my Set Theory side and my Developer side. CLR hasn’t exactly become the default option for stored procedures, although there are plenty of situations where it can be useful for getting faster performance. SQL Server 2014 is different though, through Hekaton – its In-Memory OLTP environment. When you create a table using Hekaton (that is, a memory-optimized one), the table you create is the kind of thing you’d’ve made as a developer. It creates code in C leveraging structs and pointers and arrays, which it compiles into fast code. When you insert data into it, it creates a new instance of a struct in memory, and adds it to an array. When the insert is committed, a small write is made to the transaction to make sure it’s durable, but none of the locking and latching behaviour that typifies transactional systems is needed. Indexes are done using hashes and using bw-trees (which avoid locking through the use of pointers) and by handling each updates as a delete-and-insert. This is data the way that developers do it when they’re coding for performance – the way I was taught at university before I learned about databases. Being done in C, it compiles to very quick code, and although these tables don’t support every feature that regular SQL tables do, this is still an excellent direction that has been taken. @rob_farley
