• Chess as a team building exercise for software developers

  - by maple_shaft

  The last place I worked wasn't a particularly great place and there were more than a few nights where we were working late into the evening trying to meet our sprints. The team while stressed out got pretty close and people started bringing in little mind teasers and puzzles, just something we would all play around with and try to solve while a build/deploy was running for the test environment, or while we were waiting for the integration test run to finish. Eventually it turned into people bringing chess boards in and setting them at their desks. We would play by email sending each other moves in chess notation, but at a very casual pace, with games lasting sometimes two or three days. Management tolerated this when we were putting in overtime, but as things were being managed better and people weren't working much more than 40/wk, they started cracking down on this and told us that we weren't allowed to have chess boards at our desks, although they were okay with the puzzle games. What are the pros and cons in your opinion of allowing chess during software development lull time?

• 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."

• How To Watch Netflix On Ubuntu with the Netflix Desktop App

  - by Chris Hoffman

  We previously covered watching Netflix on Linux and concluded that using a virtual machine was your best bet. There’s now an even better solution – a “Netflix Desktop” app that allows you to watch Netflix on Linux. This app is actually a package containing a patched version of Wine, the Windows build of Firefox, Microsoft Silverlight, and some tweaks to make it all work together. Previously, Silverlight would not run properly in Wine. Note: While this worked pretty well for us, it’s an unofficial solution that relies on Wine. Netflix doesn’t officially support it.

• Should a c# dev switch to VB.net when the team language base is mixed?

  - by jjr2527

  I recently joined a new development team where the language preferences are mixed on the .net platform. Dev 1: Knows VB.net, does not know c# Dev 2: Knows VB.net, does not know c# Dev 3: Knows c# and VB.net, prefers c# Dev 4: Knows c# and VB6(VB.net should be pretty easy to pick up), prefers c# It seems to me that the thought leaders in the .net space are c# devs almost universally. I also thought that some 3rd party tools didn't support VB.net but when I started looking into it I didn't find any good examples. I would prefer to get the whole team on c# but if there isn't any good reason to force the issue aside from preference then I don't think that is the right choice. Are there any reasons I should lead folks away from VB.net?

• Prototype Fanless Heatsink Is Silent and Dust-Immune

  - by Jason Fitzpatrick

  What does this chip cooler do that your’s doesn’t? Run 30 times more efficiently, nearly silently, and repel any dust that settles on it, for starters. Check out the video to see it in action. Although the video is a bit dry the heatsink in action is pretty impressive–nearly silent? repels dust? radically more efficient?

• Multi threaded game - updating, rendering, and how to split them

  - by CodeBunny

  From the StackOverflow post (it was recommended I move this): So, I'm working on a game engine, and I've made pretty good progress. However, my engine is single-threaded, and the advantages of splitting updating and rendering into separate threads sounds like a very good idea. How should I do this? Single threaded game engines are (conceptually) very easy to make, you have a loop where you update - render - sleep - repeat. However, I can't think of a good way to break updating and rendering apart, especially if I change their update rates (say I go through the update loop 25x a second, and have 60fps for rendering) - what if I begin updating halfway through a render loop, or vice versa?

• Should I avoid SharePoint Development in Visual Studio?

  - by SaphuA

  Hello, Not long ago I started an internship at a company that supplies SharePoint consultancy, hosting and development. While their consultancy seems to be pretty good and solid, I feel their development department lacks direction. The reason for this, most likely, is that they stopped outsourcing not too long ago. One thing that I've frequently bumped my head into is the following: My supervisor strongly insists that everything that can be done natively in SharePoint (somehow this includes editing xslt files in Designer) should be done in SharePoint. Even if this results in longer development time (at least when they make me write XSLT) and reduced usability. Her main arguments for this are: Better maintainability Editing the functionality doesn't require programming knowledge I feel the company is a little biassed and I am unable to get a decent discussion going. This is why I am looking for other places to get some responses on the subject (and not only on the arguments of my supervisor, but more on the subject in general). Kind regards

• Learning to implement dynamically typed language compiler

  - by TriArc

  I'm interested in learning how to create a compiler for a dynamically typed language. Most compiler books, college courses and articles/tutorials I've come across are specifically for statically typed languages. I've thought of a few ways to do it, but I'd like to know how it's usually done. I know type inferencing is a pretty common strategy, but what about others? Where can I find out more about how to create a dynamically typed language? Edit 1: I meant dynamically typed. Sorry about the confusion. I've written toy compilers for statically typed languages and written some interpreters for dynamically typed languages. Now, I'm interested in learning more about creating compilers for a dynamically typed language. I'm specifically experimenting with LLVM and since I need to specify the type of every method and argument, I'm thinking of ways to implement a dynamically typed language on something like LLVM.

• Turbo C++ to Visual Studio 2010 migration [closed]

  - by BigGenius

  OK, based on my previous questions and your help., I have gone to install Visual Studio Express. But now problem is, the programs which I successfully code at home on Visual Studio don't run on Turbo C++ compiler at school (assuming I type the program instead of exporting code). Is there anything I can do? Also I am just learning basic syntax and data handling, loops, structures, arrays and all. But Visual Studio has auto completion and pretty typing (which may be advantageous) but crap for a beginner getting hold on to language. Sorry, if I have been unclear. But what should I do? This will make me lazy programmer and will reflect in my grades. Is there any other IDE, which I can use, very similar to Turbo C++ and able to run in Windows 7 in fullsreen mode.

• Choosing 3D modeling software Maya or 3D max?

  - by Kenneth J

  I've am a developer whose has spent most of my programming life developing web and business applications. I want to try my hand at something more challenging (but stay in the comfort of Visual Studio) ...perhaps XNA. Want 3D modeling software would be best for someone developing XNA? I have played with 3d MAX and Maya but never really did anything too involved. What are the pros and cons between them (in terms of game development)? Does one win out over the other for game development? Or is it pretty much just preference? I am new to game development and just trying to figure out the best tools to use before I really started. Any advice or other suggections would be greatly appreciated.

• How can I merge two SubVersion branches to one working copy without committing?

  - by Eric Belair

  My current SubVersion workflow is like so: The trunk is used to make small content changes and bug fixes to the main source code. Branches are used for adding/editing enhancements and projects. So, trunk changes are made, tested, committed and deployed pretty quickly. Whereas, enhancements and projects need additional user testing and approval. At time, I have two branches that need testing and approval at the same time. I don't want to merge to the trunk and commit until the changes are fully tested and approved. What I need to do is merge both branches to one working copy without any commits. I am using Tortoise SVN, and when I try to merge the second branch, I get an error message: Cannot merge into a working copy that has local modifications Is there a way that I can do this without committing either merge?

  2011 8,3 Macbook Pro running 64bit 11.10. When I run sensors from the lm-sensors package, I get a lot of information, but no way to understand it: coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +53.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +53.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +52.0°C (high = +86.0°C, crit = +100.0°C) Core 2: +50.0°C (high = +86.0°C, crit = +100.0°C) Core 3: +49.0°C (high = +86.0°C, crit = +100.0°C) applesmc-isa-0300 Adapter: ISA adapter Left side : 2001 RPM (min = 2000 RPM) Right side : 2001 RPM (min = 2000 RPM) TB0T: +33.2°C TB1T: +33.2°C TB2T: +29.0°C TC0C: +52.8°C TC0D: +47.2°C TC0E: +51.8°C TC0F: +53.0°C TC0J: +1.0°C TC0P: +44.5°C TC1C: +52.0°C TC2C: +52.0°C TC3C: +52.0°C TC4C: +52.0°C TCFC: +0.2°C TCGC: +51.0°C TCSA: +52.0°C TCTD: +0.0°C TG0D: +44.5°C TG0P: +43.2°C THSP: +37.5°C TM0S: +57.5°C TMBS: +0.0°C TP0P: +50.0°C TPCD: +55.0°C The core temp info is really useful and I'm pretty sure that Left/Right Side refers to the two fans within, but otherwise, I have no idea what this information means.

• Searching for the Perfect Developer&rsquo;s Laptop.

  - by mbcrump

  I have been in the market for a new computer for several months. I set out with a budget of around $1200. I knew up front that the machine would be used for developing applications and maybe some light gaming. I kept switching between buying a laptop or a desktop but the laptop won because: With a Laptop, I can carry it everywhere and with a desktop I can’t. I searched for about 2 weeks and narrowed it down to a list of must-have’s : i7 Processor (I wasn’t going to settle for an i5 or AMD. I wanted a true Quad-core machine, not 2 dual-core fused together). 15.6” monitor SSD 128GB or Larger. – It’s almost 2011 and I don’t want an old standard HDD in this machine. 8GB of DDR3 Ram. – The more the better, right? 1GB Video Card (Prefer NVidia) – I might want to play games with this. HDMI Port – Almost a standard on new Machines. This would be used when I am on the road and want to stream Netflix to the HDTV in the Hotel room. Webcam Built-in – This would be to video chat with the wife and kids if I am on the road. 6-Cell Battery. – I’ve read that an i7 in a laptop really kills the battery. A 6-cell or 9-cell is even better. That is a pretty long list for a budget of around $1200. I searched around the internet and could not buy this machine prebuilt for under $1200. That was even with coupons and my company’s 10% Dell discount. The only way that I would get a machine like this was to buy a prebuilt and replace parts. I chose the  Lenovo Y560 on Newegg to start as my base. Below is a top-down picture of it.   Part 1: The Hardware The Specs for this machine: Color :  GrayOperating System : Windows 7 Home Premium 64-bitCPU Type : Intel Core i7-740QM(1.73GHz)Screen : 15.6" WXGAMemory Size : 4GB DDR3Hard Disk : 500GBOptical Drive : DVD±R/RWGraphics Card : ATI Mobility Radeon HD 5730Video Memory : 1GBCommunication : Gigabit LAN and WLANCard slot : 1 x Express Card/34Battery Life : Up to 3.5 hoursDimensions : 15.20" x 10.00" x 0.80" - 1.30"Weight : 5.95 lbs. This computer met most of the requirements above except that it didn’t come with an SSD or have 8GB of DDR3 Memory. So, I needed to start shopping except this time for an SSD. I asked around on twitter and other hardware forums and everyone pointed me to the Crucial C300 SSD. After checking prices of the drive, it was going to cost an extra $275 bucks and I was going from a spacious 500GB drive to 128GB. After watching some of the SSD videos on YouTube I started feeling better. Below is a pic of the Crucial C300 SSD. The second thing that I needed to upgrade was the RAM. It came with 4GB of DDR3 RAM, but it was slow. I decided to buy the Crucial 8GB (4GB x 2) Kit from Newegg. This RAM cost an extra $120 and had a CAS Latency of 7. In the end this machine delivered everything that I wanted and it cost around $1300. You are probably saying, well your budget was $1200. I have spare parts that I’m planning on selling on eBay or Anandtech.  =) If you are interested then shoot me an email and I will give you a great deal mbcrump[at]gmail[dot]com. 500GB Laptop 7200RPM HDD 4GB of DDR3 RAM (2GB x 2) faceVision HD 720p Camera – Unopened In the end my Windows Experience Rating of the SSD was 7.7 and the CPU 7.1. The max that you can get is a 7.9. Part 2: The Software I’m very lucky that I get a lot of software for free. When choosing a laptop, the OS really doesn’t matter because I would never keep the bloatware pre-installed or Windows 7 Home Premium on my main development machine. Matter of fact, as soon as I got the laptop, I immediately took out the old HDD without booting into it. After I got the SSD into the machine, I installed Windows 7 Ultimate 64-Bit. The BIOS was out of date, so I updated that to the latest version and started downloading drivers off of Lenovo’s site. I had to download the Wireless Networking Drivers to a USB-Key before I could get my machine on my wireless network. I also discovered that if the date on your computer is off then you cannot join the Windows 7 Homegroup until you fix it. I’m aware that most people like peeking into what programs other software developers use and I went ahead and listed my “essentials” of a fresh build. I am a big Silverlight guy, so naturally some of the software listed below is specific to Silverlight. You should also check out my master list of Tools and Utilities for the .NET Developer.

• Deluge bit torrent. No incoming connections?

  - by mark kirby

  Hi I keep getting a no incoming connections on my Deluge. I know this is a pretty common problem from Google, but I have posted here to see if any one knows why this happens. I have port forwarded my router and set Deluge to the correct port range. Is this just a bug ? It does not seem to affect the speed so I obviously do have incoming connections and Transmission says the ports are open. So I guess my question is why is this happening ?

• Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error on localhost

  - by Ne0

  Background: I set up a cloud server and have have a website running SSL, it was all pretty strait forward following these instructions and following the instructions given by the SSL certificate issuer. I then went to set up development site on my local machine the same way but using self signed certs using these instructions. I have checked that port 443 is open and this post suggests it is a bad configuration on the server. I have gone through the set up process twice, yet I have been unable to find out what I have done wrong or missed. Does anyone else know what I may have have missed to get this error? Note: As the links suggest this is on 12.04.

• My first Windows Phone 7 App: Getting SharePoint Content

  Earlier this week at the Mix10 conference, Microsoft announced the developer story of the Windows Phone 7 Series. As expected, its all about Silverlight! For all the details I highly recommend to watch the recorded keynotes (day 1, day 2). Tonight I could resist trying to build my very first Windows Phone 7 application; the traditional Hello World thingy. Because the developer tools (Visual Studio 2010 and the free Visual Studio 2010 Express) have pretty nice templates, that wasnt much of a challenge....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Implementing a "state-machine" logic for methods required by an object in C++

  - by user827992

  What I have: 1 hypothetical object/class + other classes and related methods that gives me functionality. What I want: linking this object to 0 to N methods in realtime on request when an event is triggered Each event is related to a single method or a class, so a single event does not necessarily mean "connect this 1 method only" but can also mean "connect all the methods from that class or a group of methods" Avoiding linked lists because I have to browse the entire list to know what methods are linked, because this does not ensure me that the linked methods are kept in a particular order (let's say an alphabetic order by their names or classes), and also because this involve a massive amount of pointers usage. Example: I have an object Employee Jon, Jon acquires knowledge and forgets things pretty easily, so his skills may vary during a period of time, I'm responsible for what Jon can add or remove from his CV, how can I implement this logic?

• Student wanting to go to a developer conference

  - by Jamie Keeling

  I'm a 21 year old student in my last year of University, and I am looking for information about developer conferences. I live in Derby (United Kingdom) and there's not (As far as I know) many conferences local to where I live. I do have a car at my disposal so travelling shouldn't be a problem. I was hoping somebody could recommend the best way to go about finding and attending a conference, which one is probably the best to go to and what kind of things I'd need to know and take beforehand. I've done a couple of Google searches and searched SO itself but nothing specific to my needs was found. Note: I'm primarily a C# developer using WPF and WinForms but I'm open to pretty much anything.

• Were you a good programmer when you first left university?

  - by dustyprogrammer

  I recently graduated, from university. I have since then joined a development team where I am by far the least experienced developer, with maybe with a couple work terms under my belt, meanwhile the rest of the team is rocking 5-10 years experience. I am/was a very good student and a pretty good programmer when it came to bottled assignments and tests. I have worked on some projects with success. But now I working with a much bigger code-base, and the learning curve is much higher... I was wondering how many other developers started out their careers in teams and left like they sucked. When does this change? How can I speed up the process? My seniors are helping me but I want to be great and show my value now. I don't to start a flame war, this is just a question I have been having and I was hoping to get some advice from other experienced developers, as well as other beginners like me.

• Uninstalling dual boot Ubuntu 12.04 LTS with Windows 7

  - by user103799

  I tried Ubuntu and decided Windows 7 was good enough for me.I tried to uninstall it but in Disk Management in Windows 7, I can't find the partition for Ubuntu. There are HP_Tools, OS (C:), Recovery (D:) and SYSTEM partitions and are all NTFS. My HDD has 250 GB, but it shows only ~230 GBs. I'm confussed about what's going on, as I'm pretty sure I had Ubuntu installed, even booted into it a few days back. I even used EaseUS. Shows the same thing as Disk Management. I've made a Ubuntu Live USB. How do I get Ubuntu off my laptop? Thanks in advance.

• Delegates in c#

  - by Jalpesh P. Vadgama

  I have used delegates in my programming since C# 2.0. But I have seen there are lots of confusion going on with delegates so I have decided to blog about it. In this blog I will explain about delegate basics and use of delegates in C#. What is delegate? We can say a delegate is a type safe function pointer which holds methods reference in object. As per MSDN it's a type that references to a method. So you can assign more than one methods to delegates with same parameter and same return type. Following is syntax for the delegate public delegate int Calculate(int a, int b); Here you can see the we have defined the delegate with two int parameter and integer parameter as return parameter. Now any method that matches this parameter can be assigned to above delegates. To understand the functionality of delegates let’s take a following simple example. using System; namespace Delegates { class Program { public delegate int CalculateNumber(int a, int b); static void Main(string[] args) { int a = 5; int b = 5; CalculateNumber addNumber = new CalculateNumber(AddNumber); Console.WriteLine(addNumber(5, 6)); Console.ReadLine(); } public static int AddNumber(int a, int b) { return a + b; } } } Here in the above code you can see that I have created a object of CalculateNumber delegate and I have assigned the AddNumber static method to it. Where you can see in ‘AddNumber’ static method will just return a sum of two numbers. After that I am calling method with the help of the delegates and printing out put to the console application. Now let’s run the application and following is the output as expected. That’s it. You can see the out put of delegates after adding a number. This delegates can be used in variety of scenarios. Like in web application we can use it to update one controls properties from another control’s action. Same you can also call a delegates whens some UI interaction done like button clicked. Hope you liked it. Stay tuned for more. In next post I am going to explain about multicast delegates. Till then happy programming.
