• Why are more programmers not freelance these days? [closed]

  - by Pierre 303

  Leaving the whole pie to only a few of them, amplifying the huge differences between the two status. Pay is a (huge) one, not having to do overtime is another. I leave the question open to hopefully get many great answers on all the different subjects that affects that feeling and decision not to go. EDIT: While this question is really global, I'll be interested in any studies, facts, articles, opinions regarding local markets such as US, India and even Australia in which I'm in love with. EDIT2: Bounty of 500 points for anyone that will come with recent studies on the subject. If multiple answers, will pick the one with the most upvotes.

• Null Or Empty Coalescing

  In my last blog post, I wrote about the proper way to check for empty enumerations and proposed an IsNullOrEmpty method for collections which sparked a lot of discussion. This post covers a similar issue, but from a different angle. A very long time ago, I wrote about my love for the null coalescing operator. However, over time, Ive found it to be not quite as useful as it could be when dealing with strings. For example, heres the code I might want to write: public static void DoSomething(string...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Getting to math applications gradually

  - by den-javamaniac

  I'm currently getting a formal degree related to computation, in particular my current focus is numerical programming, scientific computing and machine learning. I'd love to apply that knowledge in game dev and expand it with statistics, probability theory, and graph theory (probably even linear algebra). The question is: which spheres of gamedev are filled with such math stuff, is it possible to advance in those without being a part of a group of people and how to get to it gradually? P.S.: I've got experience with commercial java dev and am getting my hands on C/C++ at the moment, however, I'm opened to go ahead and try Unity3D and etc.

• UI Controls Copyright

  - by user3692481

  I'm developing a cross-platform computer software. It will run on Windows and Mac OS X. For user experience reasons, I want it to have the same graphic on both platforms. I really like the Mac OS UI controls and I'd love to see them on the Windows version too. My question is: is it legal to "copy" UI components? I'm not going to copy icons or reproduce an existing Apple software. I would only "copy" some standard UI components such as Buttons, Progressbars, TreeView, ListView etc. You can see them here: http://i.stack.imgur.com/9YzYQ.png http://i.stack.imgur.com/MWR6B.jpg IMHO, they should not be copyrighted for two reasons: They are implicitly used by any Mac OS software There are a lot of Apps (for Windows and even Web-Apps) that are "inspired by" the Mac graphic. Am I right?

• Folding at home refusing connection?

  - by user49191

  I am having a slight problem. I love contributing to folding at home, if some of you dont know what it is, it's a program that downloads work from the stanford university servers, has your computer process it (takes about 12 hours for 1 assignment depending on the processor, and then uploads it back. The problem with mine is that when I run FAHControl in terminal, it says Error 111 connection refused. This doesnt happen when i run folding at home on windows. Can someone tell me how to fix this? Thanks.

• Skype, add-on applications, UAC and "Unable to respond"

  - by Greg Low

  Just posting this blog tonight hoping it might save someone else a bunch of time. For call recording on Skype, I use a program called Pamela. Lately, when I'd first installed it, it would work fine. Later, however, it would come up and say: "Another application (Pamela.exe) is attempting to access Skype, but we are unable to respond". You just have to love these sorts of messages that don't give you the slightest clue about what the problem is. While I saw the problem with Pamela, it can happen with...(read more)

• Clip Grab for Ubuntu 12.04

  - by John Bush

  Having issues downloading the newest version of Clip Grab http://clipgrab.de/en, I tried to install it in the terminal, tried finding the software in Ubuntu Software Center, I have even tried to extract the folder for which the software is in at, no luck... When trying to install in the terminal it gives me an error about my ppa. No luck what-so-ever. I love this program, it has worked for several months, and this is annoying that I can not use this program now. Please respond back to me, I also have had no luck with response either.

• Don't Call it a Comeback

  - by Chris Haaker

  I received the email like most of you about Jeff and crew stepping down and selling the blog to another company. That it is a long time associate and friend of the team we have all grown to know and love, I feel much better about the move. Who cares, Chris, you haven't blogged religiously in ages! I know, and its a crime. Blame life, Twitter, my kids, laziness or whatever else you can think of. I always tell myself I am going to make a comeback - - "Don't call it a comeback - I been here for years." But after a few posts I seem to lose my steam. Its hard to explain, hell, I can't explain it. But we'll see what happens this time. Just don't call it a comeback.  2012 rMBP 15" Quad Core 2.33 GHz 16GB Memory 258GB SSDMarsEdit 3.5 (Please Microsoft Live Team - Make LiveWriter for OS X)

• User eXperience

  - by Daniel Moth

  The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

• Contract-Popup at Login

  - by Steve

  I want to give my notebook to guests of my little Hotel as an extra service. I love the Ubuntu guest-account and I think that this is the best possible way to help my guests get free internet-access. I found out how to "design" their user-accounts with /etc/skel, but unfortunately I have no clue, how to show them a small introduction to the system and a kind of user-agreement "contract" when they login. I read of xmessage, but this is too minimalistic. I'd like to implement some pictures. Does anyone have any idea of how to make this possible? Would it be possible that the user is logged out automatically if he rejects the user-agreement? Thank you so much in advance, Steve.

• Math major as a viable degree

  - by Zak O'Keefe

  While I realize there are many topics about CS vs software engineering vs game school programs, I haven't found anything relating to whether pure math degrees (with CS minor and electives) would also be a viable program. By this I mean: Would having a math major, CS minor put one at competitive disadvantage as compared to a pure CS program? This relates specifically to game engine programming, more on the graphics side. Background (for those who care): Currently a math major, CS minor at school and looking to land a career doing graphics engine programming. Admittedly, I love math and if at all possible would like to stay my current program as long as it doesn't put me at a competitive disadvantage trying to land a job post-graduation. That being said, I'm strong in the traditional C/C++ languages, strong concurrent programming skills, and currently produce self-made games for iOS. As an employer, how badly is the math major hurting me? Just want to get some advice from people already in the field!

• Why doesn't Microsoft support virtualizing a Server OS on Windows 7?

  - by Nathan DeWitt

  Microsoft doesn't support any server operating systems in Windows Virtual PC. Virtual Server 2005 doesn't run on Windows 7. Hyper-V is great, but I don't want to run Server 2008 as my main OS, and I love having Windows 7 run on the bare metal. I don't want to mess around with a dual boot. My only option to continue developing in Windows 7 with a virtual server environment on hand is VMWare or VirtualBox. Other members in my team use Hyper-V, and VHDs are common. I'd prefer to be able to use their VHDs, so that leaves me VirtualBox. Does anyone know if Microsoft is planning on bringing server virtualization back to the workstation?

• Elantech trackpad being identified as a logitech wheel mouse.

  - by Nathan Cox

  I recently purchased a Samsung RF510 laptop computer, which I absolutely love. However, upon installing Ubuntu 10.10 onto it I couldn't get the trackpad to function properly. It worked as a basic mouse (point and click) but had no functionality for edge scrolling or any of the multitouch settings the trackpad is capable of. After doing a lot of research I discovered the reason is a known issue where the Ubuntu kernel will improperly detect an Elantech trackpad as a logitech PS/2 wheel mouse, and as such will gain none of the functionality that seems to be coded for synaptics trackpads. The question I have is: does anyone know a way to get this working properly? This is my first time trying to run Ubuntu on a laptop (actually, it's my first laptop in the last 12 years) and I'm finding the experience to be intolerable without the basic scrolling/zooming/etc I've been used to using for as long as I can remember.

• How essential is it to make a service layer?

  - by BornToCode

  I started building an app in 3 layers (DAL, BL, UI) [it mainly handles CRM, some sales reports and inventory]. A colleague told me that I must move to service layer pattern, that developers came to service pattern from their experience and it is the better approach to design most applications. He said it would be much easier to maintain the application in the future that way. Personally, I get the feeling that it's just making things more complex and I couldn't see much of a benefit from it that would justify that. This app does have an additional small partial ui that uses some (but only few) of the desktop application functions so I did find myself duplicating some code (but not much). Just because of some code duplication I wouldn't convert it to be service oriented, but he said I should use it anyway because in general it's a very good architecture, why programmers are so in love with services?? I tried to google on it but I'm still confused and can't decide what to do.

• How do I avoid "Developer's Bad Optimization Intuition"?

  - by Mona

  I saw on a article that put forth this statement: Developers love to optimize code and with good reason. It is so satisfying and fun. But knowing when to optimize is far more important. Unfortunately, developers generally have horrible intuition about where the performance problems in an application will actually be. How can a developer avoid this bad intuition? Are there good tools to find which parts of your code really need optimization (for Java)? Do you know of some articles, tips, or good reads on this subject?

• Adsense alternative for a "Sex Education" website?

  - by WhatIsOpenID

  I am creating a nice and niche "Sex Education" website. No porn, nothing offensive and no scams. I would love to place Google Adsense but they do not allow ads on adult sites. I would like to know what advertising and link-exchange like should I place on my site. My sole objective is to cover the server costs and salary of one or two persons. (In this way, it is different from Best alternative to Adsense for a small website?).

• How to model interentity membership in entity-component architecture?

  - by croxis

  I'm falling in love with simple grace of entity-component design, although I still have issues breaking from MVC and OOP practices. Some of my game entities have membership relationships with each other (ex: a player is a member of a city, a city is a member of a nation), and I am unsure on the best way to implement it. My initial reaction is to have a a MemberOfCity component that points to the appropriate city component, but components are suppose to have no references to each other. My other option is to have a System do it, but that would require the system to persist data outside of a component. Is there a clean way to do this in an entity-component design, or am I trying to use a hammer on a screw and should use a hybrid/another approach?

• Git bug branching convention

  - by kisplit

  I've been following the successful Git branching model guide for most of my development. I still wonder if the way I handle bug tickets is correct. My current workflow: Once I accept a bug ticket I will do a git checkout -b bug/{ticket_number}, create a single commit as a fix and then checkout develop and do a git merge --no-ff. I'd love to hear from the experiences of others whether or not I am abusing the --no-ff option in this instance. If I am, could someone suggest a better approach?

• Algorithms for rainfall + river creation in procedurally generated terrain

  - by Peck

  I've recently become fascinated by the things that can be done with procedurally terrain and have started experimenting with world building a bit. I'd like to be able to make worlds something like Dwarf fortress with biomes created from meshing together various maps. So first step has been done. Using the diamond-square algorithm I've created some nice hieghtmaps. Next step is I would like to add some water features and have them somewhat realistically generated with rainfall. I've read about a few different approaches such as starting at the high points of the map, and "stepping" down to the lowest neighboring point, pooling/eroding as it works its way down to sea level. Are there any documented algorithms with this or are they more off the cuff? Would love any advice/thoughts.

• Soft lockup after upgrade - cannot install from live CD

  - by nbm

  I dual-boot MacIntel Core 2 duo. nVidia graphics. Ran upgrade from ubuntu 13.10 to 14.04 (64 bit). On restart ran into {numbers} Bug: soft lockup - CPU#0 stuck for 22s! [swapper/0:1] Tried loading earlier kernel: same problem Tried re-installing ubuntu from a liveCD that has worked in the past: version 13.04. Same problem. Tried re-partitioning hard drive using Mac OS X disk utility and then installing ubuntu 14.04LTS from liveCD. Same problem. Not possible to verify liveCD disk (creates same "soft lockup" bug.) Tried installing from the liveCD with version 13.04 that I know works (that's how I got Ubuntu on this machine in the first place.) Same problem. I know this is not a hardware problem as OS X works just fine, I am using it right now on the same machine. I have been using various versions of Ubuntu for 2 years. Things I cannot do: Open a terminal Verify CD image Start ubuntu from CD (same soft lockup problem) This problem is similar to some other questions, none of which have been satisfactorily answered: Ubuntu 14.04 soft lockup on Vostro 3500 Cannot do fresh install of Ubuntu 13.04 while booting from DVD: "soft lockup" bug Live CD stalls when installing Ubuntu 13.10 UPDATE 6/11/14: Following some much-appreciated advice from bain (see below) I burned a 12.04LTS disk and started with kernel parameters: noapic, no1apic, acpi=off, nomodeset, elevator=deadline, and clocksource=jiffies. With all of these parameters I was able to load the 12.04LTS CD ("Try without installing"). It worked fine. However, as soon as I tried to install Ubuntu from the CD, my wired ethernet (eth0) connection would hang. There are already various askubuntu questions and bug reports about this problem, none of which had answers for me. (E.g., dhclient eth0 does nothing, none of the various reset commands does anything, manually setting IP &etc does nothing. I could reliably kill the ethernet connection by clicking "install ubuntu" every single time.) I could go ahead and install 12.04 without an internet connection, but the install would freeze after mostly completing (I tried several times.) There were some relevant error messages in the details of the install output script that, IIRC, had to do with searching for missing files and not being able to access eth0 (internet) to get them. To be honest I gave up at that point and I'm not sure I wrote those down. If I find some notes I will post them. At this point I no longer have Ubuntu on my system. I wiped the partitions and am using exclusively OS X. I am leaving this question in case it helps anyone else with similar problems. I love open source and I love Linux, and the next machine I get I will probably just build from Arch. At the moment I miss repositories and a lot of other things about Ubuntu, but the OS X terminal is 'nix, I can pretty much use all the open source apps I like, and while I am not a fan of the Apple software it gets the job done for me. Unlike Ubuntu, which can't even install. I realize this isn't necessarily a place for a soapbox speech, but when I first installed 12.04 several years ago there were already people in the community complaining that Canonical was going too "commercial". But I loved it. Several years later and all I've seen is Canonical adding more not-so-useful bells and whistles to Ubuntu while continually failing to fix basic problems on upgrades. With a dual-boot (and sometimes triple-boot) system it always took me some tweaking to get an upgrade to work, and to some extent that is okay. But at this point I feel like Canonical ought to just put a price tag on Ubuntu. All I see is more commercialism and advertising and product tie-ins, and ongoing problems do not get fixed. I am a big fan of open-source, not-for profit enterprise. I am also a big fan of for-profit enterprise, which certainly has its place and usefulness. I am not a fan of companies who pretend to be in favor of open source but really are just out to make a buck, and IMNSHO that is what Canonical has become. This is a great community and I wish you all the best, but my next install of Linux will not be Ubuntu.

• How to survive if you can only do things your way as a programmer?

  - by niceguyjava

  I hate hibernate, I hate spring and I am the kind of programmer who likes to do things his way. I hate micro-management and other people making decisions for me about what framework I should use, what patterns I should apply (hate patterns too) and what architecture I should design. I consider myself a successful programmer and have a descent financial situation due to my performance in past jobs, but I just can't take the standard Java jobs out there. I really love to design things from scratch and hate when I have to maintain other people's bad code, design and architecture, which is the majority you find out there for sure. Does anybody relate to that? What do you guys recommend me? Open up my on company, do consulting, or just keep looking hard until I find a job that suits my preferences, as hard as this may look like with all the hibernate and spring crap out there?
