• Join the Visual Studio diagnostics team

  - by Daniel Moth

  I have a Program Manager position open on the Visual Studio diagnostics team which owns the debugger, the profiler tools, and IntelliTrace. If you have never worked for Microsoft you may be wondering if the PM position at Microsoft is for you. Read the job description to see what the role entails and to see if you are a fit. I’ll preempt the usual question and say that this is a Redmond-based position. Beyond that, if you are interested in what you read and you think you have what it takes, then email me. http://www.microsoft-careers.com/job/Redmond-Program-Manager-2-Job-WA-98052/2321458/ Comments about this post by Daniel Moth welcome at the original blog.

• Wine can't find gnome-keyring-pkcs11.so

  - by Jackie

  I am trying to start a program using wine on ubuntu lts 12.04 64 bit When I do this I get the following error message... /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: cannot open shared object file: No such file or directory When I try to symlink the 64 bit libraries, of course I get the following... jackie@jackie-Latitude-E6410:~/tmp/AC$ wine TTG.exe p11-kit: couldn't load module: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: wrong ELF class: ELFCLASS64 wine: Unhandled page fault on read access to 0x00000000 at address (nil) (thread 0009), starting debugger... err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr 0x7bc47aac Is there a package that installs the 32-bit as well as the 64bit?

• What is a practical way to debug Rails?

  - by Joshua Fox

  I get the impression that in practice, debuggers are rarely used for Rails applications. (Likewise for other Ruby apps, as well as Python.) We can compare this to the usual practice for Java or VisualStudio programmers--they use an interactive debugger in a graphical IDE. How do people debug Rails applications in practice? I am aware of the variety of debuggers, so no need to mention those, but do serious Rails programmers work without them? If so, why do you choose to do it this way? It seems to me that console printing has its limits when debugging complex logic.

• Windows Workflow Foundation (WF) and things I wish were more intuitive

  - by pjohnson

  I've started using Windows Workflow Foundation, and so far ran into a few things that aren't incredibly obvious. Microsoft did a good job of providing a ton of samples, which is handy because you need them to get anywhere with WF. The docs are thin, so I've been bouncing between samples and downloadable labs to figure out how to implement various activities in a workflow. Code separation or not? You can create a workflow and activity in Visual Studio with or without code separation, i.e. just a .cs "Component" style object with a Designer.cs file, or a .xoml XML markup file with code behind (beside?) it. Absence any obvious advantage to one or the other, I used code separation for workflows and any complex custom activities, and without code separation for custom activities that just inherit from the Activity class and thus don't have anything special in the designer. So far, so good. Workflow Activity Library project type - What's the point of this separate project type? So far I don't see much advantage to keeping your custom activities in a separate project. I prefer to have as few projects as needed (and no fewer). The Designer's Toolbox window seems to find your custom activities just fine no matter where they are, and the debugging experience doesn't seem to be any different. Designer Properties - This is about the designer, and not specific to WF, but nevertheless something that's hindered me a lot more in WF than in Windows Forms or elsewhere. The Properties window does a good job of showing you property values when you hover the mouse over the values. But they don't do the same to find out what a control's type is. So maybe if I named all my activities "x1" and "x2" instead of helpful self-documenting names like "listenForStatusUpdate", then I could easily see enough of the type to determine what it is, but any names longer than those and all I get of the type is "System.Workflow.Act" or "System.Workflow.Compone". Even hitting the dropdown doesn't expand any wider, like the debugger quick watch "smart tag" popups do when you scroll through members. The only way I've found around this in VS 2008 is to widen the Properties dialog, losing precious designer real estate, then shrink it back down when you're done to see what you were doing. Really? WF Designer - This is about the designer, and I believe is specific to WF. I should be able to edit the XML in a .xoml file, or drag and drop using the designer. With WPF (at least in VS 2010 Ultimate), these are side by side, and changes to one instantly update the other. With WF, I have to right-click on the .xoml file, choose Open With, and pick XML Editor to edit the text. It looks like this is one way where WF didn't get the same attention WPF got during .NET Fx 3.0 development. Service - In the WF world, this is simply a class that talks to the workflow about things outside the workflow, not to be confused with how the term "service" is used in every other context I've seen in the Windows and .NET world, i.e. an executable that waits for events or requests from a client and services them (Windows service, web service, WCF service, etc.). ListenActivity - Such a great concept, yet so unintuitive. It seems you need at least two branches (EventDrivenActivity instances), one for your positive condition and one for a timeout. The positive condition has a HandleExternalEventActivity, and the timeout has a DelayActivity followed by however you want to handle the delay, e.g. a ThrowActivity. The timeout is simple enough; wiring up the HandleExternalEventActivity is where things get fun. You need to create a service (see above), and an interface for that service (this seems more complex than should be necessary--why not have activities just wire to a service directly?). And you need to create a custom EventArgs class that inherits from ExternalDataEventArgs--you can't create an ExternalDataEventArgs event handler directly, even if you don't need to add any more information to the event args, despite ExternalDataEventArgs not being marked as an abstract class, nor a compiler error nor warning nor any other indication that you're doing something wrong, until you run it and find that it always times out and get to check every place mentioned here to see why. Your interface and service need an event that consumes your custom EventArgs class, and a method to fire that event. You need to call that method from somewhere. Then you get to hope that you did everything just right, or that you can step through code in the debugger before your Delay timeout expires. Yes, it's as much fun as it sounds. TransactionScopeActivity - I had the bright idea of putting one in as a placeholder, then filling in the database updates later. That caused this error: The workflow hosting environment does not have a persistence service as required by an operation on the workflow instance "[GUID]". ...which is about as helpful as "Object reference not set to an instance of an object" and even more fun to debug. Google led me to this Microsoft Forums hit, and from there I figured out it didn't like that the activity had no children. Again, a Validator on TransactionScopeActivity would have pointed this out to me at design time, rather than handing me a nearly useless error at runtime. Easily enough, I disabled the activity and that fixed it. I still see huge potential in my work where WF could make things easier and more flexible, but there are some seriously rough edges at the moment. Maybe I'm just spoiled by how much easier and more intuitive development elsewhere in the .NET Framework is.

• How Microsoft Lost the API War - by Joel Spolsky

  - by TechTwaddle

  Came across another gem of an article by Joel Spolsky. It's a pretty old article written in June of 2004, has lot of tidbits and I really enjoyed reading it, so much in fact that I read it twice! So hit the link below and give it a read if you haven't already, How Microsoft Lost the API War - Joel Spolsky excerpt, "I first heard about this from one of the developers of the hit game SimCity, who told me that there was a critical bug in his application: it used memory right after freeing it, a major no-no that happened to work OK on DOS but would not work under Windows where memory that is freed is likely to be snatched up by another running application right away. The testers on the Windows team were going through various popular applications, testing them to make sure they worked OK, but SimCity kept crashing. They reported this to the Windows developers, who disassembled SimCity, stepped through it in a debugger, found the bug, and added special code that checked if SimCity was running, and if it did, ran the memory allocator in a special mode in which you could still use memory after freeing it."

• GlassFish Clustering with DCOM on Windows

  - by ByronNevins

  DCOM - Distributed COM, a Microsoft protocol for communicating with Windows machines. Why use DCOM? In GlassFish 3.1 SSH is used as the standard way to run commands on remote nodes for clustering.  It is very difficult for users to get SSH configured properly on Windows.  SSH does not come with Windows so we have to depend on third party tools.  And then the user is forced to install and configure these tools -- which can be tricky. DCOM is available on all supported platforms.  It is built-in to Windows. The idea is to use DCOM to communicate with remote Windows nodes.  This has the huge advantage that the user has to do minimal, if any, configuration on the Windows nodes. Implementation HighlightsTwo open Source Libraries have been added to GlassFish: Jcifs – a SAMBA implementation in Java J-interop – A Java implementation for making DCOM calls to remote Windows computers.   Note that any supported platform can use DCOM to work with Windows nodes -- not just Windows.E.g. you can have a Linux DAS work with Windows remote instances.All existing SSH commands now have a corresponding DCOM command – except for setup-ssh which isn’t needed for DCOM.  validate-dcom is an all new command. New DCOM Commands create-node-dcom delete-node-dcom install-node-dcom list-nodes-dcom ping-node-dcom uninstall-node-dcom update-node-dcom validate-dcom setup-local-dcom (This is only available via Update Center for GlassFish 3.1.2) These commands are in-place in the trunk (4.0).  And in the branch (3.1.2) Windows Configuration Challenges There are an infinite number of possible configurations of Windows if you look at it as a combination of main release, service-pack, special drivers, software, configuration etc.  Later versions of Windows err on the side of tightening security be default.  This means that the Windows host may need to have configuration changes made.These configuration changes mostly need to be made by the user.  setup-local-dcom will assist you in making required changes to the Windows Registry.  See the reference blogs for details. The validate-dcom Command validate-dcom is a crucial command.  It should be run before any other commands.  If it does not run successfully then there is no point in running other commands.The validate-dcom command must be used from a DAS machine to test a different Windows machine.  If  validate-dcom runs successfully you can be confident that all the DCOM commands will work.  Conversely, the opposite is also true:  If validate-dcom fails, then no DCOM commands will work. What validate-dcom does Verify that the remote host is not the local machine. Resolves the remote host name Checks that the remote DCOM port is being listened on (135, 139) Checks that the remote host’s File Sharing is enabled (port 445) It copies a file (a script) to the remote host to verify that SAMBA is working and authorization is correct It runs a script that it copied on-the-fly to the remote host. Tips and Tricks The bread and butter commands that use DCOM are existing commands like create-instance, start-instance etc.   All of the commands that have dcom in their name are for dealing with the actual nodes. The way the software works is to call asadmin.bat on the remote machine and run a command.  This means that you can track these commands easily on the remote machine with the usual tools.  E.g. using AS_LOGFILE, looking at log files, etc.  It’s easy to attach a debugger to the remote asadmin process, “just in time”, if necessary. How to debug the remote commands:Edit the asadmin.bat file that is in the glassfish/bin folder.  Use glassfish/lib/nadmin.bat in GlassFish 4.0+Add these options to the java call:-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1234  Now if you run, say start-instance on DAS, you can attach your debugger, at your leisure, to the remote machines port 1234.  It will be running start-local-instance and patiently waiting for you to attach.

• Can I get any logging and error output from Flash?

  - by Dave M G

  To further provide better information for my other question about browsers and Pulse audio, I wanted to see if I could get some kind of helpful log information. I've looked at logs from both Pulseaudio and Firefox, but don't see anything like an error in either of them. The problem I'm experiencing may be coming from Flash. Is there a way I can trap specifically any log output from Flash? Update: I've downloaded the Linux Flash Player 10.3 Plugin content debugger, and I've installed libflashplayer.so in ~/.mozilla/firefox/plugins/, and copied the user/* files to /user. I've also set up mm.cfg to say: ErrorReportingEnable=1 TraceOutputFileEnable=1 MaxWarnings=50 TraceOutputFileName=/home/dave/.macromedia/Flash_Player/Logs/flashlog.txt And I rebooted just to be sure everything was starting fresh. However, after playing a Flash video from Youtube, flashlog.txt is not being generated. How can I be sure that logging is in fact enabled, so I can tell whether I'm simply not getting errors or I haven't set up logging correctly?

• LIMBO fails on startup with Internal errors - invalid parameters received

  I installed LIMBO from the Humble Bundle V and as far as I am aware, this has wine packaged with it (I also installed the latest from the repo's in case is was because of that).

• SpriteBatch.end() generating null pointer exception

  - by odaymichael

  I am getting a null pointer exception using libGDX that the debugger points as the SpriteBatch.end() line. I was wondering what would cause this. Here is the offending code block, specifically the batch.end() line: batch.begin(); for (int j = 0; j < 3; j++) for (int i = 0; i < 3; i++) if (zoomgrid[i][j].getPiece().getImage() != null) zoomgrid[i][j].getPiece().getImage().draw(batch); batch.end(); The top of the stack is actually a line that calls lastTexture.bind(); In the flush() method of com.badlogic.gdx.graphics.g2d.SpriteBatch. I appreciate any input, let me know if I haven't included enough information.

• How to convincing Programmers that 'being in the zone' [coding] isn't always beneficial for the project?

  - by hawkeye

  In this book review: http://books.slashdot.org/story/11/06/13/1251216/Book-Review-The-Clean-Coder?utm_source=slashdot&utm_medium=twitter Chapter 4 talks about the coding process itself. One of the hardest statements the book makes here is to stay out of "the zone" when coding. Bob asserts that you lose parts of the big picture when you go down to that level. While I may struggle with that assertion, I do agree with his next statement that debugging time is expensive, so you should avoid having to do debugger-driven development whenever possible. He finishes the chapter with examples of pacing yourself (walking away, taking a shower) and how to deal with being late on your projects (remembering that hope is not a plan, and being clear about the impact of overtime) along with a reminder that it is good to both give and receive help, whether it be small questions or mentoring others. they talk about how 'being in the zone' - can actually be detrimental to the project. How do you convince your team members that this is the case?

• How do I improve my code reading skills

  - by Andrew

  Well the question is in the title - how do I improve my code reading skills. The software/hardware environment I currently do development in is quite slow with respect to compilation times and time it takes the whole system to test. The system is quite old/complex and thus splitting it into a several smaller, more manageable sub-projects is not feasible in a neare future. I have realized is what really hinders the development progress is my code reading skills. How do I improve my code reading skills, so I can spot most of the errors and issues in the code even before I hit the "do compile" key, even before I start the debugger?

• Five development tools I can't live without

  - by bconlon

  When applying to join Geeks with Blogs I had to specify the development tools I use every day. That got me thinking, it's taken a long time to whittle my tools of choice down to the selection I use, so it might be worth sharing. Before I begin, I appreciate we all have our preferred development tools, but these are the ones that work for me. Microsoft Visual Studio Microsoft Visual Studio has been my development tool of choice for more years than I care to remember. I first used this when it was Visual C++ 1.5 (hats off to those who started on 1.0) and by 2.2 it had everything I needed from a C++ IDE. Versions 4 and 5 followed and if I had to guess I would expect more Windows applications are written in VC++ 6 and VB6 than any other language. Then came the not so great versions Visual Studio .Net 2002 (7.0) and 2003 (7.1). If I'm honest I was still using v6. 2005 was better and 2008 was simply brilliant. Everything worked, the compiler was super fast and I was happy again...then came 2010...oh dear. 2010 is a big step backwards for me. It's not encouraging for my upcoming WPF exploits that 2010 is fronted in WPF technology, with the forever growing Find/Replace dialog, the issues with C++ intellisense, and the buggy debugger. That said it is still my tool of choice but I hope they sort the issue in SP1. I've tried other IDEs like Visual Age and Eclipse, but for me Visual Studio is the best. A really great tool. Liquid XML Studio XML development is a tricky business. The W3C standards are often difficult to get to the bottom of so it's great to have a graphical tool to help. I first used Liquid Technologies 5 or 6 years back when I needed to process XML data in C++. Their excellent XML Data Binding tool has an easy to use Wizard UI (as compared to Castor or JAXB command line tools) and allows you to generate code from an XML Schema. So instead of having to deal with untyped nodes like with a DOM parser, instead you get an Object Model providing a custom API in C++, C#, VB etc. More recently they developed a graphical XML IDE with XML Editor, XSLT, XQuery debugger and other XML tools. So now I can develop an XML Schema graphically, click a button to generate a Sample XML document, and click another button to run the Wizard to generate code including a Sample Application that will then load my Sample XML document into the generated object model. This is a very cool toolset. Note: XML Data Binding is nothing to do with WPF Data Binding, but I hope to cover both in more detail another time. .Net Reflector Note: I've just noticed that starting form the end of February 2011 this will no longer be a free tool !! .Net Reflector turns .Net byte code back into C# source code. But how can it work this magic? Well the clue is in the name, it uses reflection to inspect a compiled .Net assembly. The assembly is compiled to byte code, it doesn't get compiled to native machine code until its needed using a just-in-time (JIT) compiler. The byte code still has all of the information needed to see classes, variables. methods and properties, so reflector gathers this information and puts it in a handy tree. I have used .Net Reflector for years in order to understand what the .Net Framework is doing as it sometimes has undocumented, quirky features. This really has been invaluable in certain instances and I cannot praise enough kudos on the original developer Lutz Roeder. Smart Assembly In order to stop nosy geeks looking at our code using a tool like .Net Reflector, we need to obfuscate (mess up) the byte code. Smart Assembly is a tool that does this. Again I have used this for a long time. It is very quick and easy to use. Another excellent tool. Coincidentally, .Net Reflector and Smart Assembly are now both owned by Red Gate. Again kudos goes to the original developer Jean-Sebastien Lange. TortoiseSVN SVN (Apache Subversion) is a Source Control System developed as an open source project. TortoiseSVN is a graphical UI wrapper over SVN that hooks into Windows Explorer to enable files to be Updated, Committed, Merged etc. from the right click menu. This is an essential tool for keeping my hard work safe! Many years ago I used Microsoft Source Safe and I disliked CVS type systems. But TortoiseSVN is simply the best source control tool I have ever used. --- So there you have it, my top 5 development tools that I use (nearly) every day and have helped to make my working life a little easier. I'm sure there are other great tools that I wish I used but have never heard of, but if you have not used any of the above, I would suggest you check them out as they are all very, very cool products. #

• The next step for a graduate?

  - by Michael Hobbs

  I will complete my degree in Computer Science in July of 2013 however I will have two years of military service left. I would like to get some hands on C#/C++ programming experience in the mean time. I have been looking around the web at all the open source project that are out there. There are literally 10's of thousands. How would you go about picking one that is: A) good for a graduate level programmer B) will probably go somewhere, and C) are willing to take a novice under their wing. I would even be happy to work for a company for free, remotely as a debugger, tester, or what have you. As a side note would prefer to stick in the C# realm but understand I need to branch out at the same time.

• Slides for Parallel Debugging windows

  Recently I gave a talk at our Microsoft Shanghai offices on Parallel Programming so I had to update my existing Beta1 deck to Beta2 content. Specifically for Parallel Tasks and Parallel Stacks, I used 5 slides to accompany the demo.In case you are giving talks on parallelism within Visual Studio 2010, please feel free to download and use the updated parallel debugger slides (pptx).TIP: The slides have animations so be sure to F5 the deck for the full benefit and they also have text in the Comments section so be sure to see them at design time too. Comments about this post welcome at the original blog.

• How do I include Implementation and Usage Documentation in one file

  - by Angelo.Hannes

  There are two types of documentation. One type, the Implementation Documentation, contains information about specific implementation of a construct (eg. Class, Method, etc.). It is targeted to the future me, maintainer, debugger and so on. And there is Usage Documentation, containing information how to use a provided api. It does not contain information about specific implementation and is targeted to users of the api. How do I include both of them in one file? (Or do I include both of them in one file? And if not, what type belongs into the source file?) Are there special techniques, using java-doc and/or best practices?

• How to program something with the expectation that it will work the first time?

  - by Peter Turner

  I had a friend in college who programmed something that worked the first time, that was pretty amazing. But as for me, I just fire up the debugger as soon as I finally get whatever I'm working on to compile - saves me time (kidding of course, I sometimes hold out a little bit of hope or use a lot of premeditated debug strings). What's the best way to approach the Dijkstrain ideal for our programs? -or- Is this just some sort of pie-in-the-sky old fools quest for greatness applicable only to finite tasks that no one should hope for in our professional lives because programming is just too complex?

• YouTube: Up & Running with Twitter Bootstrap

  - by Geertjan

  "Twitter Bootstrap is a free collection of tools for creating websites and web applications. It contains HTML and CSS-based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions. It is the most popular project on GitHub and has been used by NASA and MSNBC among others." (Wikipedia) Normally, when you read "getting started" instructions for Twitter Bootstrap, you're told to download various things from various sites. Then you're told to set up various folders and files, etc. What if it could be much simpler than that? Spend 7 minutes with me in this (silent) screencast and you'll see a complete development environment for developing applications with Twitter Bootstrap: Two things that could be added to the movie are the JavaScript debugger, the support for responsive design via switching between form factors in the embedded browser and Chrome with the NetBeans plugin, as well as how to convert the application to a native Android or iOS package via in-built Cordova support.

• Developing instincts and "subconscious debugging" [closed]

  - by ggambett

  For some time now (a couple of years, perhaps?) I've noticed something that happens when I'm writing code. I write something with a syntax error, or some other subtle error. I don't really notice it on a conscious level, but I have a weird feeling about what I just wrote. I then try to compile it and I get a warning or error on the line that provoked the feeling. Lately I've been trying to pay attention to these feelings as they happen, and more often than not, I find errors right there. It's like I'm developing a subconscious debugger (or at least subconscious syntax checking ;)) I've heard of people fixing bugs in their sleep (I did a couple of times), but I don't think I've heard this kind of thing. Does it happen to someone else?

• Programming Interview : How to debug a program?

  - by Jake

  I was recently asked the following question in an interview : How do you debug a C++ program ? I started by explaining that programs may have syntax and semantic errors. Compiler reports the syntax errors which can be corrected. For semantic errors, various debuggers are available. I specifically talked about gdb, which is command line, and Visual Studio IDE's debugger, which has a GUI, and common commands. I also talked about debug and release version of code, how assertions should be used for debug build, how exceptions helps in automatic cleanup & putting the program in valid state, and how logging can be useful (e.g. using std::clog). I want to know if this answer is complete or not. Also, I want to hear how other people will go about answering this question in a structured manner ? Thanks.
