• DirectCompute Lectures

  - by Daniel Moth

  Previously I shared resources to get you started with DirectCompute, for taking advantage of GPGPUs in an a way that doesn't tie you to a hardware vendor (e.g. nvidia, amd). I just stumbled upon and had to share a lecture series on channel9 on DirectCompute! Here are direct links to the episodes that are up there now: DirectCompute Expert Roundtable Discussion DirectCompute Lecture Series 101- Introduction to DirectCompute DirectCompute Lecture Series 110- Memory Patterns DirectCompute Lecture Series 120- Basics of DirectCompute Application Development DirectCompute Lecture Series 210- GPU Optimizations and Performance DirectCompute Lecture Series 230- GPU Accelerated Physics DirectCompute Lecture Series 250- Integration with the Graphics Pipeline Having watched these I recommend them all, but if you only want to watch a few, I suggest #2, #3, #4 and #5. Also, you should download the "WMV (High)" so you can see the code clearly and be able to Ctrl+Shift+G for fast playback… TIP: To subscribe to channel9 GPU content, use this RSS feed.

• Ask the Readers: Are You A Second Screen Multi-tasker?

  - by Jason Fitzpatrick

  Television watchers are no longer keeping their eyes continuously glued to the screen–increasingly smartphone, tablet, and laptop users have merged their mobile device and television time. Are you one of the second screen multi-taskers? Image courtesy of Umani, a TV-companion application for iPad. According to Nielsen user surveys, at least 80% of mobile device owners have used their device while watching television in the past month–27% said they use their mobile device alongside the television multiple times a day. What the survey results are light on, however, is an in depth look at what the users are doing with their second screen. This week we want to hear about whether or not you’re one of the second screen multi-taskers and what you use your mobile device for during your television/movie time. Sound off in the comments and then check back in on Friday for the What You Said roundup.

• Massive Minecraft Creation Is a Functional Graphing Calculator

  - by Jason Fitzpatrick

  We’re no stranger to cool Minecraft creations, but this project takes Minecraft design to a whole new level. An industrious teen has built functional graphing calculator out of Minecraft blocks. It’s an absolutely enormous project that, if constructed in real life instead of in a virtual Minecraft space, would loom over a city. To fully appreciate how much ingenuity and effort went into the project, we’d suggest hitting up the comments over at Slashdot where commenters discuss the numerous obstacles and design tricks he would have needed to overcome and employ to pull the project off.

• Need advice on design in Ruby On Rails

  - by Elad

  For personal educational purposes I am making a site for a conference. One of the object that exist in a conference is a session, which has different states and in each state it has slightly different attributes: When submitted it has a speaker (User in the system), Title and abstract. When under review it has reviews and comments (in addition to the basic data) When accepted it has a defined time-slot but no reviewers anymore. I feel that it is not the best thing to add a "status" attributes and start adding many if statements... So I thought it would be better to have different classes for each state each with it's own validations and behaviors. What do you think about this design? Do you have a better idea? *I must add this out of frustration: I had several edits of the question, including one major change but no one actually gave any hint or clue on which direction should i take or where is a better place to ask this... Hardly helpful.

• PPL and TPL sessions on channel9

  - by Daniel Moth

  Back in June there was an internal conference in Redmond ("Engineering Forum") aimed at Microsoft engineers, and delivered by Microsoft engineers. I was asked to put together a track on Multi-Core development, so I picked 6 parallelism experts and we created 6 awesome sessions (we won the top spot in the Top 10 :-)). Two of the speakers kept the content fairly external-friendly, so we received permission to publish their recordings publicly. Enjoy (best to download the High Quality WMV): Don McCrady - Parallelism in C++ Using the Concurrency Runtime Stephen Toub - Implementing Parallel Patterns using .NET 4 To get notified on future videos on parallelism (or to browse the archive) stay tuned on this channel9 parallel computing feed.

• Do you own your tools?

  - by Mike Brown

  A colleague of mine wrote a post a while ago asking Do you own your tools. It raises an important question. Do you? I answered way down in the comments. As an independent, I do own my tools. Even when I wasn't independent, I had my own (fully licensed) tools that I used for personal development. I don't think buying your own tools are something to puff your chest up about (just because you can buy a $100 pair of basketball sneakers they won't make you as good as Michael Jordan), but it IS an investment in yourself that shouldn't be taken lightly. What do you think good people?

• MSVC 2008 - Unresolved External errors with LIB but only with DLL, not with EXE project

  - by Robert Oschler

  I have a DLL that I am trying to link with a libjpeg LIB using MSVC 2008 that is generating Unresolved External Symbol errors for the libjpeg functions. I also have a test project that links with the exact same libjpeg library file and links without error and runs fine too. I have triple-checked my LIB path and dependent LIBS list settings and literally copy and pasted them from the EXE project to the DLL project. I still get the errors. I do have the libjpeg include headers surrounded by extern "C" so it is not a name mangling issue and the unresolved external warnings show the "missing" libjpeg functions as undecorated (just a leading underscore and the @ sign parameter byte count suffix after each name). What could make the linker with the DLL project be unable to find the functions properly when the test EXE project has no trouble at all? I'm using the pre-compiled 32-bit static multi-threaded debug library which I downloaded from ClanLib. Thanks, Robert

• Cross-Browser Extension Installation now Possible with Opera and Google Chrome

  - by Akemi Iwaya

  People have been curious if there would be cross-browser compatibility for extensions due to Opera’s recent switch to the browser engine that Google Chrome uses. That question has now been answered. The OMG! Chrome! Blog has put together a nice tutorial on how to get cross-browser extension compatibility set up and working with your browser of choice. Screenshot courtesy of OMG! Chrome! Blog. While it is not surprising that the first steps in cross-browser extension compatibility have been taken, it will be interesting to see how it develops as the process is refined and further development occurs with the ‘new’ Opera. What are your thoughts on this? Is cross-browser extension compatibility really that important? Perhaps you feel that it does not matter? Let us know your thoughts in the comments!

• Visual Studio Async CTP

  - by Daniel Moth

  While most of the buzz at the recent PDC here at Microsoft's headquarters has been about Windows Azure and Windows Phone, there is a truly noteworthy technology that as a .NET developer (of any kind of application) you should pay attention to, even in its early technology preview stage: Visual Studio Async CTP. I could provide many more direct links, but you do not need them: just visit the home page of this technology to download whitepapers, watch videos on how this technology integrates with C# and with VB, (through the new async and await language keywords) as well as videos on how the technology works under the covers (based largely on the Task Parallel Library). More importantly, download the actual bits (they install on top of your Visual Studio 2010), which include many samples. Get ready for a revolution in Asynchronous Programming with C# and Visual Basic. Comments about this post welcome at the original blog.

• Java or Python for internet application?

  - by jpartogi

  In choosing a technology for internet applications where the number of users may scale over time, which one should we consider: Java or Python? What are the considerations in choosing one and not the other? If speed and scalability is our main criteria, which one should we use? We have looked around and it seems that there are more websites that use Python [i.e : Quora, digg, reddit, bitbucket and disqus] than Java. Based on that, can we say that Python is more suitable for internet applications where speed and scalability is the main criteria? However we have browsed around and found some comments saying that Java is actually faster than Python. Thank you for your insights.

• FCGI htaccess handler

  - by sharvey

  I'm trying to setup django on a shared hosting provider. I followed the instructions on http://helpdesk.bluehost.com/index.php/kb/article/000531 and almost have it working. The problem I'm facing now is that the traffic is properly routed throught the fcgi file, but the file itself shows up as plain text in the browser. If I run ./mysite.fcgi in the ssh shell, I do get the default django welcome page. my .htaccess is: AddHandler fastcgi-script .fcgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ mysite.fcgi/$1 [QSA,L] and mysite.fcgi: #!/usr/bin/python2.6 import sys, os os.environ['DJANGO_SETTINGS_MODULE'] = "icm.settings" from django.core.servers.fastcgi import runfastcgi runfastcgi(method="threaded", daemonize="false") thanks.

• Why is thread local storage so slow?

  - by dsimcha

  I'm working on a custom mark-release style memory allocator for the D programming language that works by allocating from thread-local regions. It seems that the thread local storage bottleneck is causing a huge (~50%) slowdown in allocating memory from these regions compared to an otherwise identical single threaded version of the code, even after designing my code to have only one TLS lookup per allocation/deallocation. This is based on allocating/freeing memory a large number of times in a loop, and I'm trying to figure out if it's an artifact of my benchmarking method. My understanding is that thread local storage should basically just involve accessing something through an extra layer of indirection, similar to accessing a variable via a pointer. Is this incorrect? How much overhead does thread-local storage typically have? Note: Although I mention D, I'm also interested in general answers that aren't specific to D, since D's implementation of thread-local storage will likely improve if it is slower than the best implementations.

• Is Google Closure a true compiler?

  - by James Allardice

  This question is inspired by the debate in the comments on this Stack Overflow question. The Google Closure Compiler documentation states the following (emphasis added): The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. However, Wikipedia gives the following definition of a "compiler": A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language... A language rewriter is usually a program that translates the form of expressions without a change of language. Based on that, I would say that Google Closure is not a compiler. But the fact that Google explicitly state that it is in fact a "true compiler" makes me wonder if there's more to it. Is Google Closure really a JavaScript compiler?

• linux pthread_suspend

  - by johnnycrash

  Looks like linux doesnt implement pthread_suspend and continue, but I really need em. I have tried cond_wait, but it is too slow. The work being threaded mostly executes in 50us but occasionally executes upwards of 500ms. The problem with cond_wait is two-fold. The mutex locking is taking comparable times to the micro second executions and I don't need locking. Second, I have many worker threads and I don't really want to make N condition variables when they need to be woken up. I know exactly which thread is waiting for which work and could just pthread_continue that thread. A thread knows when there is no more work and can easily pthread_suspend itself. This would use no locking, avoid the stampede, and be faster. Problem is....no pthread_suspend or _continue. Any ideas?

• Architecture of interaction modes ("paint tools") for a 3D paint program

  - by Bernhard Kausler

  We are developing a Qt-based application to navigate through and paint on a volume treated as a 3D pixel graphic. The layout of the app consists of three orthogonal slice views on which the user may paint stuff like dots, circles etc. and also erase already painted pixels. Think of a 3D Gimp or MS Paint. How would you design the the architecture for the different interaction modes (i.e. paint tools)? My idea is: use the MVC pattern have a separate controler for every interaction mode install an event filter on all three slice views to collect all incoming user interaction events (mouse, keyboard) redirect the events to the currently active interaction controler I would appreciate critical comments on that idea.

• Monitoring pthread context switching

  - by simon

  I would like to monitor the the context switching behavior in a multi-threaded pthread application. In other RTOSes(Micro C OS) I have been able to register a context switch callback for each thread in the application, and then log (or toggle a gpio) and watch the thread context switching in real time. This was a valuable tool for debugging the real time behavior and interaction of the multiple threads. My current environment is embedded linux utilizing the pthread api. Is there a way to montior each of the context switches?

• Being prepared for a code review as a developer?

  - by Karthik Sreenivasan

  I am looking for some ideas here. I read the article How should code reviews be Carried Out and Code Reviews, what are the advantages? which were very informative but I still need more clarity on the question below. My Question is, Being the target developer, can you suggest some best practices a developer can incorporate before his code is going get reviewed. Currently I practice the following methods PPT for a logical flow Detailed comments. Issue: Even though I have implemented the above practices, they do not help on the review. The problem I faced is, when certain logic is referred, I keep searching for the implementation and the flow and too much time is wasted in the process and I get on people’s nerve. I think a lot of developers would be going through what I am going through as well.

• Great Example of Community How-To Doc

  - by ultan o'broin

  Always on the lookout for examples of community doc, and here's a great one: Chet Justice (@oraclenerd) just launched an eBook version (PDF actually) of John Piwowar's (@jpiwowar) very popular multi-part E-Business Suite Installation Guide. You can obtain it using the PayPal buttons here. All in a good cause too. Creation of how-to information like this for functional or technical tasks, along with working examples about post-install steps, configurations and customizations, is what an applications community value-add is all about. Each community is different of course, an Adobe PhotoShop community might be more interested in templates. Great to see the needs of the community being met like this. If you have other examples you'd like to share, then find the comments.
