  • Some notes on Reflector 7

    - by CliveT
    Both Bart and I have blogged about some of the changes that we (and other members of the team) have made to .NET Reflector for version 7, including the new tabbed browsing model, the inclusion of Jason Haley's PowerCommands add-in and some improvements to decompilation such as handling iterator blocks. The intention of this blog post is to cover all of the main new features in one place, and to describe the three new editions of .NET Reflector 7. If you'd simply like to try out the latest version of the beta for yourself you can do so here. Three new editions .NET Reflector 7 will come in three new editions: .NET Reflector .NET Reflector VS .NET Reflector VSPro The first edition is just the standalone Windows application. The latter two editions include the Windows application, but also add the power of Reflector into Visual Studio so that you can save time switching tools and quickly get to the bottom of a debugging issue that involves third-party code. Let's take a look at some of the new features in each edition. Tabbed browsing .NET Reflector now has a tabbed browsing model, in which the individual tabs have independent histories. You can open a new tab to view the selected object by using CTRL+CLICK. I've found this really useful when I'm investigating a particular piece of code but then want to focus on some other methods that I find along the way. For version 7, we wanted to implement the basic idea of tabs to see whether it is something that users will find helpful. If it is something that enhances productivity, we will add more tab-based features in a future version. PowerCommands add-in We have also included Jason Haley's PowerCommands add-in as part of version 7. This add-in provides a number of useful commands, including support for opening .xap files and extracting the constituent assemblies, and a query editor that allows C# queries to be written and executed against the Reflector object model . All of the PowerCommands features can be turned on from the options menu. We will be really interested to see what people are finding useful for further integration into the main tool in the future. My personal favourite part of the PowerCommands add-in is the query editor. You can set up as many of your own queries as you like, but we provide 25 to get you started. These do useful things like listing all extension methods in a given assembly, and displaying other lower-level information, such as the number of times that a given method uses the box IL instruction. These queries can be extracted and then executed from the 'Run Query' context menu within the assembly explorer. Moreover, the queries can be loaded, modified, and saved using the built-in editor, allowing very specific user customization and sharing of queries. The PowerCommands add-in contains many other useful utilities. For example, you can open an item using an external application, work with enumeration bit flags, or generate assembly binding redirect files. You can see Bart's earlier post for a more complete list. .NET Reflector VS .NET Reflector VS adds a brand new Reflector object browser into Visual Studio to save you time opening .NET Reflector separately and browsing for an object. A 'Decompile and Explore' option is also added to the context menu of references in the Solution Explorer, so you don't need to leave Visual Studio to look through decompiled code. We've also added some simple navigation features to allow you to move through the decompiled code as quickly and easily as you can in .NET Reflector. When this is selected, the add-in decompiles the given assembly, Once the decompilation has finished, a clone of the Reflector assembly explorer can be used inside Visual Studio. When Reflector generates the source code, it records the location information. You can therefore navigate from the source file to other decompiled source using the 'Go To Definition' context menu item. This then takes you to the definition in another decompiled assembly. .NET Reflector VSPro .NET Reflector VSPro builds on the features in .NET Reflector VS to add the ability to debug any source code you decompile. When you decompile with .NET Reflector VSPro, a matching .pdb is generated, so you can use Visual Studio to debug the source code as if it were part of the project. You can now use all the standard debugging techniques that you are used to in the Visual Studio debugger, and step through decompiled code as if it were your own. Again, you can select assemblies for decompilation. They are then decompiled. And then you can debug as if they were one of your own source code files. The future of .NET Reflector As I have mentioned throughout this post, most of the new features in version 7 are exploratory steps and we will be watching feedback closely. Although we don't want to speculate now about any other new features or bugs that will or won't be fixed in the next few versions of .NET Reflector, Bart has mentioned in a previous post that there are lots of improvements we intend to make. We plan to do this with great care and without taking anything away from the simplicity of the core product. User experience is something that we pride ourselves on at Red Gate, and it is clear that Reflector is still a long way off our usual standards. We plan for the next few versions of Reflector to be worked on by some of our top usability specialists who have been involved with our other market-leading products such as the ANTS Profilers and SQL Compare. I re-iterate the need for the really great simple mode in .NET Reflector to remain intact regardless of any other improvements we are planning to make. I really hope that you enjoy using some of the new features in version 7 and that Reflector continues to be your favourite .NET development tool for a long time to come.

  • Are there any plans to create a standard based on libunity?

    - by Sebastian Billaudelle
    In the last few month and maybe even years, Ubuntu and Canonical often were criticised for developing software and desktop components without talking to other groups in the free software community. I don't want to comment on this topic, but I see problems arising with creating a "proprietary" solution for displaying indicators and progressbars with a launcher like Unity. In the world of free and open Desktop Environments we often try to standardize parts and libraries or write specifications to increase collaboration between different desktops. We have the instrument of http://freedesktop.org and a lot of specifications are getting implemented by the major Desktop Environments. In this context, proposing a standard for those indicators would be a great step towards better interoperability between desktops. These indicators represent a great feature on the Linux Desktop and I'm sure that other projects like AWN, Docky, etc. would pick them up. With the great market share of Ubuntu, Canonical is in a position to propose it as a standard and encourage projects to implement it. Thank you in advance, Sebastian Billaudelle

  • What are the best resources for learning about concurrency and multi-threaded applications?

    - by Zepee
    I realised I have a massive knowledge gap when it comes to multi-threaded applications and concurrent programming. I've covered some basics in the past, but most of it seems to be gone from my mind, and it is definitely a field that I want, and need, to be more knowledgeable about. What are the best resources for learning about building concurrent applications? I'm a very practical oriented person, so if said book contains concrete examples the better, but I'm open to suggestions. I personally prefer to work in pseudocode or C++, and a slant toward game development would be best, but not required.

  • Fonts look horrible in any java application

    - by Eirik Berg
    All fonts in java applications look horrible. I have seen a few questions about this previously, but they are quite old now(11.04 was the most recent, but that didn't seem to be the same problem). For some reason java applications do not use the system font (Ubuntu 11), but rather some elongated font that doesn't seem to have any anti-aliasing. So what I'm asking is if this is an open bug(couldn't find any on launchpad), something the developers have done wrong, or if there is a way to configure the fonts used in java application. Perhaps this is just a shortcoming of openjdk and I should install the Sun version instead? Attached an image showing jitsi, but the problem is also present in minecraft, my internet-bank and anything else involving java. I'm on 12.04, but since I couldn't find anything on launchpad I'm assuming that isn't relevant. Edit: actually managed to forget the picture... Thanks!

  • Google s'attaque au marché de la télévision, Android bientôt dans nos écrans

    Google s'attaque au marché de la télévision, Android bientôt dans nos écrans Après avoir investi les smartphones, les netbooks et les tablettes, Android arriverait dans nos écrans. Le système d'exploitation open-source de Google devrait en effet tenter de se faire une place dans no téléviseurs, en surfant sur la tendance des TV connectées au Net. En effet, lors du CES 2010 à Las Vegas, les fabriquants ont tous présentés de futurs modèles d'écrans permettant de surfer sur le web. Le géant de la recherche en ligne aurait donc décidé, en partenariat avec Intel et Sony, de partir à l'assaut de ce créneau très porteur. Android sera intégré soit dans le poste de télévision (qui comprendrait u...

  • Becoming A Great Developer

    - by Lee Brandt
    Image via Wikipedia I’ve been doing the whole programming thing for awhile and reading and watching some of the best in the business. I have come to notice that the really great developers do a few things that (I think) makes them great. Now don’t get me wrong, I am not saying that I am one of these few. I still struggle with doing some of the things that makes one great at development. Coincidently, many of these things also make you a better person period. Believe That Guidance Is Better Than Answers This is one I have no problem with. I prefer guidance any time I am learning from another developer. Answers may get you going, but guidance will leave you stranded. At some point, you will come across a problem that can only be solved by thinking for yourself and this is where that guidance will really come in handy. You can use that guidance and extrapolate whatever technology to salve that problem (if it’s the right tool for solving that problem). The problem is, lots of developers simply want someone to tell them, “Do this, then this, then set that, and write this.” Favor thinking and learn the guidance of doing X and don’t ask someone to show you how to do X, if that makes sense. Read, Read and Read If you don’t like reading, you’re probably NOT going to make it into the Great Developer group. Great developers read books, they read magazines and they read code. Open source playgrounds like SourceForge, CodePlex and GitHub, have made it extremely easy to download code from developers you admire and see how they do stuff. Chances are, if you read their blog too, they’ll even explain WHY they did what they did (see “Guidance” above). MSDN and Code Magazine have not only code samples, but explanations of how to use certain technologies and sometimes even when NOT to use that same technology. Books are also out on just about every topic. I still favor the less technology centric books. For instance, I generally don’t buy books like, “Getting Started with Jiminy Jappets”. I look for titles like, “How To Write More Effective Code” (again, see guidance). The Addison-Wesley Signature Series is a great example of these types of books. They teach technology-agnostic concepts. Head First Design Patterns is another great guidance book. It teaches the "Gang Of Four" Design Patterns in a very easy-to-understand, picture-heavy way (I LIKE pictures). Hang Your Balls Out There Even though the advice came from a 3rd-shift Kinko’s attendant, doesn’t mean it’s not sound advice. Write some code and put it out for others to read, criticize and castigate you for. Understand that there are some real jerks out there who are absolute geniuses. Don’t be afraid to get some great advice wrapped in some really nasty language. Try to take what’s good about it and leave what’s not. I have a tough time with this myself. I don’t really have any code out there that is available for review (other than my demo code). It takes some guts to do, but in the end, there is no substitute for getting a community of developers to critique your code and give you ways to improve. Get Involved Speaking of community, the local and online user groups and discussion forums are a great place to hear about technologies and techniques you might never come across otherwise. Mostly because you might not know to look. But, once you sit down with a bunch of other developers and start discussing what you’re interested in, you may open up a whole new perspective on it. Don’t just go to the UG meetings and watch the presentations either, get out there and talk, socialize. I realize geeks weren’t meant to necessarily be social creatures, but if you’re amongst other geeks, it’s much easier. I’ve learned more in the last 3-4 years that I have been involved in the community that I did in my previous 8 years of coding without it. Socializing works, even if socialism doesn’t. Continuous Improvement Lean proponents might call this “Kaizen”, but I call it progress. We all know, especially in the technology realm, if you’re not moving ahead, you’re falling behind. It may seem like drinking from a fire hose, but step back and pick out the technologies that speak to you. The ones that may you’re little heart go pitter-patter. Concentrate on those. If you’re still overloaded, pick the best of the best. Just know that if you’re not looking at the code you wrote last week or at least last year with some embarrassment, you’re probably stagnating. That’s about all I can say about that, cause I am all out of clichés to throw at it. :0) Write Code Great painters paint, great writers write, and great developers write code. The most sure-fire way to improve your coding ability is to continue writing code. Don’t just write code that your work throws on you, pick that technology you love or are curious to know more about and walk through some blog demo examples. Take the language you use everyday and try to get it to do something crazy. Who knows, you might create the next Google search algorithm! All in all, being a great developer is about finding yourself in all this code. If it is just a job to you, you will probably never be one of the “Great Developers”, but you’re probably okay with that. If, on the other hand, you do aspire to greatness, get out there and GET it. No one’s going hand it to you.

  • What are best practices when giving a presentation to programmers?

    - by blunders
    I've watched 50 plus presentations on programming topics, although most have been online; example, Google Tech Talks -- and have ad-hoc experience on what formats work for programmers, or practices to take into account when presenting to a group of programmers. That said, I'm open to any suggestions, but here's some topic of the top of my head: Programming Jokes, Images, etc. Posting Code for download Contact Info Collecting feedback Presenting Code on Screen If it matters, in this case -- I'm giving a presentation on using a scripting language to extract, transform and load data to a local user group who's focus is the scripting language; Ruby in this case. Questions, feedback, requests -- just comment, thanks!!

  • Protecting PDF files and XDO.CFG

    - by Greg Kelly
    Protecting PDF files and XDO.CFG Security related properties can be overridden at runtime through PeopleCode as all other XMLP properties using the SetRuntimeProperties() method on the ReportDefn class. This is documented in PeopleBooks. Basically this method need to be called right before calling the processReport() method: . . &asPropName = CreateArrayRept("", 0); &asPropValue = CreateArrayRept("", 0); &asPropName.Push("pdf-open-password"); &asPropValue.Push("test"); &oRptDefn.SetRuntimeProperties(&asPropName, &asPropValue); &oRptDefn.ProcessReport(&sTemplateId, %Language_User, &dAsOfDate, &sOutputFormat); Of course users should not hardcode the password value in the code, instead, if password is stored encrypted in the database or somewhere else, they can use Decrypt() api

  • Java - learning / migrating fast

    - by Yippie-Kai-Yay
    This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo". I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java. I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though). Now, what should I do (in your opinion) to prepare myself for this Java interview. I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you. But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview? Thank you.

  • Plymouth did not install properly

    - by David Starkey
    I was installing the plymouth manager in hopes of making a custom loading screen. While the terminal was working, my computer unexpectedly powered off. I can open up the manager and it appears to do what it is supposed to (minus the fact that I can't make my own theme) and the screen only shows on powering down. Anyway, all of the advice I have seen so far have resulted in errors and nothing getting fixed. I do not have permissions to simply select the folder and delete it for some reason and I have not been able to find out how to grant myself those permissions. I guess my question then is how do I get rid of the plymouth manager so I can reinstall it properly? Already tried: -Installation - http://www.noobslab.com/2011/11/install-plymouth-manager-and-change.html -Removal - How to remove Plymouth Boot Animation manager and keep the default boot screen -Permissions - How do I change my user permissions to edit /etc/apt/sources.list? -Theming Guide - http://brej.org/blog/?p=158

  • Chromium/Chrome tabs crashes on Ubuntu/Edubuntu 12.04.3

    - by Joakim Waern
    For some reason the tabs of Chromium and Chrome have started to crash (He's dead Jim) when running on Ubuntu or Edubuntu 12.04.3. It seems to happen only when I log in. I tried the browsers on Ubuntu 13.10 and everything worked fine. Any suggestions? Ps. The browser doesn't crash, just the tabs, and I can open new ones (but they also crash after a while). Here's the output command free on the terminal after a tab crash: total used free shared buffers cached Mem: 2041116 1722740 318376 0 2868 267256 -/+ buffers/cache: 1452616 588500 Swap: 2085884 104 2085780 Compared to the output before the crash: total used free shared buffers cached Mem: 2041116 1967108 74008 0 14632 253036 -/+ buffers/cache: 1699440 341676 Swap: 2085884 40 2085844

  • Amanda Todd&ndash;What Parents Can Learn From Her Story

    - by D'Arcy Lussier
    Amanda Todd was a bullied teenager who committed suicide this week. Her story has become headline news due in part to her You Tube video she posted telling her story:   The story is heartbreaking for so many reasons, but I wanted to talk about what we as parents can learn from this. Being the dad to two girls, one that’s 10, I’m very aware of the dangers that the internet holds. When I saw her story, one thing jumped out at me – unmonitored internet access at an early age. My daughter (then 9) came home from a friends place once and asked if she could be in a YouTube video with her friend. Apparently this friend was allowed to do whatever she wanted on the internet, including posting goofy videos. This set off warning bells and we ensured our daughter realized the dangers and that she was not to ever post videos of herself. In looking at Amanda’s story, the access to unmonitored internet time along with just being a young girl and being flattered by an online predator were the key events that ultimately led to her suicide. Yes, the reaction of her classmates and “friends” was horrible as well, I’m not diluting that. But our youth don’t fully understand yet that what they do on the internet today will follow them potentially forever. And the people they meet online aren’t necessarily who they claim to be. So what can we as parents learn from Amanda’s story? Parents Shouldn’t Feel Bad About Being Internet Police Our job as parents is in part to protect our kids and keep them safe, even if they don’t like our measures. This includes monitoring, supervising, and restricting their internet activities. In our house we have a family computer in the living room that the kids can watch videos and surf the web. It’s in plain view of everyone, so you can’t hide what you’re looking at. If our daughter goes to a friend’s place, we ask about what they did and what they played. If the computer comes up, we ask about what they did on it. Luckily our daughter is very up front and honest in telling us things, so we have very open discussions. Parents Need to Be Honest About the Dangers of the Internet I’m sure every generation says that “kids grow up so fast these days”, but in our case the internet really does push our kids to be exposed to things they otherwise wouldn’t experience. One wrong word in a Google search, a click of a link in a spam email, or just general curiosity can expose a child to things they aren’t ready for or should never be exposed to (and I’m not just talking about adult material – have you seen some of the graphic pictures from war zones posted on news sites recently?). Our stance as parents has been to be open about discussing the dangers with our kids before they encounter any content – be proactive instead of reactionary. Part of this is alerting them to the monsters that lurk on the internet as well. As kids explore the world wide web, they’re eventually going to encounter some chat room or some Facebook friend invite or other personal connection with someone. More than ever kids need to be educated on the dangers of engaging with people online and sharing personal information. You can think of it as an evolved discussion that our parents had with us about using the phone: “Don’t say ‘I’m home alone’, don’t say when mom or dad get home, don’t tell them any information, etc.” Parents Need to Talk Self Worth at Home Katie makes the point better than I ever could (one bad word towards the end): Our children need to understand their value beyond what the latest issue of TigerBeat says, or the media who continues flaunting physical attributes over intelligence and character, or a society that puts focus on status and wealth. They also have to realize that just because someone pays you a compliment, that doesn’t mean you should ignore personal boundaries and limits. What does this have to do with the internet? Well, in days past if you wanted to be social you had to go out somewhere. Now you can video chat with any number of people from the comfort of wherever your laptop happens to be – and not just text but full HD video with sound! While innocent children head online in the hopes of meeting cool people, predators with bad intentions are heading online too. As much as we try to monitor their online activity and be honest about the dangers of the internet, the human side of our kids isn’t something we can control. But we can try to influence them to see themselves as not needing to search out the acceptance of complete strangers online. Way easier said than done, but ensuring self-worth is something discussed, encouraged, and celebrated is a step in the right direction. Parental Wake Up Call This post is not a critique of Amanda’s parents. The reality is that cyber bullying/abuse is happening every day, and there are millions of parents that have no clue its happening to their children. Amanda’s story is a wake up call that our children’s online activities may be putting them in danger. My heart goes out to the parents of this girl. As a father of daughters, I can’t imagine what I would do if I found my daughter having to hide in a ditch to avoid a mob or call 911 to report my daughter had attempted suicide by drinking bleach or deal with a child turning to drugs/alcohol/cutting to cope. It would be horrendous if we as parents didn’t re-evaluate our family internet policies in light of this event. And in the end, Amanda’s video was meant to bring attention to her plight and encourage others going through the same thing. We may not be kids, but we can still honour her memory by helping safeguard our children.

  • How to set Default Web Browser, Mail Client, Video Player & Music Player in the system

    - by Luis Alvarado
    I am trying to find the option that sets, for the whole system the default Web Browser, Mail Client, Video Player and Music Player instead of having to do it for each type of file. I knew where the option was in 11.04 but somehow I can not find it again. Just to not get anymore confused I am not talking about right clicking a file then changing the "Open With" to the one I want. The option I am looking for affects everything in general, so if I change, for example, the default video player to VLC, all movies will be watched with VLC. I am using Unity.

  • Learning a new language using broken unit tests

    - by Brian MacKay
    I was listening to a dot net rocks the other day where they mentioned, almost in passing, a really intriguing tool for learning new languages -- I think they were specifically talking about F#. It's a solution you open up and there are a bunch of broken unit tests. Fixing them walks you through the steps of learning the language. I want to check it out, but I was driving in my car and I have no idea what the name of the project is or which dot net rocks episode it was. Google hasn't helped much. Any idea?

  • Databinding to an Entity Framework in WPF

    - by King Chan
    Is it good to use databinding to Entity Framework's Entity in WPF? I created a singleton entity framework context: To have only one connection and it won't open and close all the time. So I can pass the Entity around to any class, and can modify the Entity and make changes to the database. All ViewModels getting the entity out from the same Context and databinding to the View saves me time from mapping new object, but now I imagine there is problem in not using the newest Context: A ViewModel databinding to a Entity, then someone else updated the data. The ViewModel will still display the old data, because the Context is never being dispose to refresh. I always create new Context and then dispose of it. If I want to pass the Entity around, then there will be conflicts between Context and Entity. What is the suggested way of doing this ?

  • Sony Vaio Webcam

    - by Martin H
    I have a in-built webcam in my Sony Vaio VGN-FE21M. lsusb shows me the device Bus 001 Device 003: ID 0ac8:c002 Z-Star Microelectronics Corp. Visual Communication Camera VGP-VCC1 and it is working within Skype most of the time. Sometimes, however, lsusb shows me the exact same output, but trying to test my cam in v4l2ucp I get the error Unable to open file /dev/video0 No such file or directory A reboot fixes the problem but I just can't pinpoint what the difference is between a working and a not working webcam and the time/instance this occurs. It would probably be a fix if i could unmount and remount the cam, but how can I do this with in-built devices? Any other advice is welcome as well.

  • Using Hadooop (HDInsight) with Microsoft - Two (OK, Three) Options

    - by BuckWoody
    Microsoft has many tools for “Big Data”. In fact, you need many tools – there’s no product called “Big Data Solution” in a shrink-wrapped box – if you find one, you probably shouldn’t buy it. It’s tempting to want a single tool that handles everything in a problem domain, but with large, complex data, that isn’t a reality. You’ll mix and match several systems, open and closed source, to solve a given problem. But there are tools that help with handling data at large, complex scales. Normally the best way to do this is to break up the data into parts, and then put the calculation engines for that chunk of data right on the node where the data is stored. These systems are in a family called “Distributed File and Compute”. Microsoft has a couple of these, including the High Performance Computing edition of Windows Server. Recently we partnered with Hortonworks to bring the Apache Foundation’s release of Hadoop to Windows. And as it turns out, there are actually two (technically three) ways you can use it. (There’s a more detailed set of information here: http://www.microsoft.com/sqlserver/en/us/solutions-technologies/business-intelligence/big-data.aspx, I’ll cover the options at a general level below)  First Option: Windows Azure HDInsight Service  Your first option is that you can simply log on to a Hadoop control node and begin to run Pig or Hive statements against data that you have stored in Windows Azure. There’s nothing to set up (although you can configure things where needed), and you can send the commands, get the output of the job(s), and stop using the service when you are done – and repeat the process later if you wish. (There are also connectors to run jobs from Microsoft Excel, but that’s another post)   This option is useful when you have a periodic burst of work for a Hadoop workload, or the data collection has been happening into Windows Azure storage anyway. That might be from a web application, the logs from a web application, telemetrics (remote sensor input), and other modes of constant collection.   You can read more about this option here:  http://blogs.msdn.com/b/windowsazure/archive/2012/10/24/getting-started-with-windows-azure-hdinsight-service.aspx Second Option: Microsoft HDInsight Server Your second option is to use the Hadoop Distribution for on-premises Windows called Microsoft HDInsight Server. You set up the Name Node(s), Job Tracker(s), and Data Node(s), among other components, and you have control over the entire ecostructure.   This option is useful if you want to  have complete control over the system, leave it running all the time, or you have a huge quantity of data that you have to bulk-load constantly – something that isn’t going to be practical with a network transfer or disk-mailing scheme. You can read more about this option here: http://www.microsoft.com/sqlserver/en/us/solutions-technologies/business-intelligence/big-data.aspx Third Option (unsupported): Installation on Windows Azure Virtual Machines  Although unsupported, you could simply use a Windows Azure Virtual Machine (we support both Windows and Linux servers) and install Hadoop yourself – it’s open-source, so there’s nothing preventing you from doing that.   Aside from being unsupported, there are other issues you’ll run into with this approach – primarily involving performance and the amount of configuration you’ll need to do to access the data nodes properly. But for a single-node installation (where all components run on one system) such as learning, demos, training and the like, this isn’t a bad option. Did I mention that’s unsupported? :) You can learn more about Windows Azure Virtual Machines here: http://www.windowsazure.com/en-us/home/scenarios/virtual-machines/ And more about Hadoop and the installation/configuration (on Linux) here: http://en.wikipedia.org/wiki/Apache_Hadoop And more about the HDInsight installation here: http://www.microsoft.com/web/gallery/install.aspx?appid=HDINSIGHT-PREVIEW Choosing the right option Since you have two or three routes you can go, the best thing to do is evaluate the need you have, and place the workload where it makes the most sense.  My suggestion is to install the HDInsight Server locally on a test system, and play around with it. Read up on the best ways to use Hadoop for a given workload, understand the parts, write a little Pig and Hive, and get your feet wet. Then sign up for a test account on HDInsight Service, and see how that leverages what you know. If you're a true tinkerer, go ahead and try the VM route as well. Oh - there’s another great reference on the Windows Azure HDInsight that just came out, here: http://blogs.msdn.com/b/brunoterkaly/archive/2012/11/16/hadoop-on-azure-introduction.aspx

  • Desktop shortcut to create a new desktop shortcut doesn't do anything

    - by David M. Karr
    It's weird that creating desktop shortcuts is currently so primitive. I found the following: Create Shortcut / launcher on Desktop in Ubuntu 12.04 That helps. However, if there's something wrong with the shortcut, it just doesn't do anything. For instance, I tried to create a shortcut for this command line to create a shortcut. When I double-click it, it just does nothing. This is the resulting text of my "Create Desktop Shortcut.desktop" file on the desktop: [Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[en_CA]=gnome-panel-launcher Exec=/usr/bin/gnome-desktop-item-edit ~/Desktop/ --create-new Name[en_CA]=Create Desktop Shortcut Name=Create Desktop Shortcut Icon=gnome-panel-launcher As I said, when I double-click this, or right-click it and select Open, nothing happens. Is there a log file where something about this would be written to?

  • Canon Mx772 printer recognized, drivers loaded...but all print jobs "Held"

    - by user212169
    BRAND NEW to Ubuntu but loving it so far. I have a Canon MX772 wireless printing running on my network and am able to print fine from a PC and Mac. Using the printers IP, Ubuntu was able to find it and I accepted all of the "recommended" items (it found a Canon MX770 driver). Everything seems to load fine...but the test page does not print, nor does any print commands make it to the printer. If I open the print dialogue jobs are shown as "held" and when I look at the jobs attributes, I see "Job printer state message=cannot specify model number" and then a few lines down "job state reasons=aborted by system". If I try to "resume" it immediately goes back to "held". I can successfully ping the IP of the printer. Would be very appreciative of other ideas...printing is the last check in the box before I am all set up. Thanks!
