• As a young student aspiring to have a career as a programmer, how should I feel about open source software?

  - by Matt

  Every once in a while on some technology websites a headline like this will pop up: http://www.osor.eu/news/nl-moving-to-open-source-would-save-government-one-to-four-billion My initial thought about government and organizations moving to open source software is that tons of programmers would lose their jobs and the industry would shrink. At the same time the proliferation and use of open source software seems to be greatly encouraged in many programming communities. Is my thinking that the full embrace of open source software everywhere will hurt the software industry a misconception? If it is not, then why do so many programmers love open source software?

• Why should most logic be in the monitor objects and not in the thread objects when writing concurrent software in Java?

  - by refuser

  When I took the Realtime and Concurrent programming course our lecturer told us that when writing concurrent programs in Java and using monitors, most of the logic should be in the monitor and as little as possible in the threads that access it. I never really understood why and I really would like to. Let me clarify. In this particular case we had several classes. Lift extends Thread Person extends Thread LiftView Monitor, all methods synchronized. This is nothing we came up with, our task was to implement a lift simulation with persons waiting on different floors, and theses were the class skeletons that were given. Then our lecturer said to implement most of the logic in the monitor (he was talking about class Monitor as THE monitor) and as little as possible in the threads. Why would he make a statement like that?

• What Master degree should a programmer have after "ITC"? [closed]

  - by Saleh Feek

  I am sorry if the question is simple. I studied ITC - Information Technology and Computing program, in an Arab university called "Arab Open University". This university actually takes the courses from the Open University in the UK (through a partnership). (Note: some of the courses in the list are different from what I took due to replacement/updating for materials) .......... I am interested in programming in general. It is the same question but in different ways: What is the master degree that is related to a programmer? Generally for someone like me, what is the required/suggested Master degree? For any suggested Master degree please type the formal name for the master degree, so that I can search for it.

• how can we have a person to allot and track tasks in agile development

  - by vignesh

  I understand that Agile team should be self organized and self driven, but is there a provision that I can have someone who will allot tasks to developers and ensure that all user stories will be completed on time?? For example if there are two persons in an agile team who are not self motivated to take up tasks and they will work only when task is assigned to them with a deadline, how can we deal this in Agile? The problem I face is that no one is fixing the deadlines for the tasks and the team is under delivering for the last two sprints. It will be better if we can have someone who can fix deadlines. IS there a provision for this in Agile

• How do you update copyright notices?

  - by James

  So now it's 2011, and as I carry on coding on our active projects it's time to update some copyright notices. eg. Copyright Widgets Ltd 2010 to Copyright Widgets Ltd 2010, 2011 My question is when do you update the copyright notices? Do you change the notice in the head of a file the first time you work on that file? Since a module is one piece of code consisting of many files that work together, do you update all notices in that module when you change a single file in that module? Since a program is one piece of code (maybe consisting of many modules), do you update all notices in that program when you change a single file in that program? Or do you just go through and change en-mass over your morning coffee on the grounds your about to start programming and updateing things?

• Choosing a crossplatform for mobile development

  - by Mech0z

  I am creating a enterprise project and will develop the app for WP, Android and IPhone (Maybe also tablets) I have then done some research of what solutions are out there and have narrowed my choice down to 3 platforms (Due to my requirement to work with Bluetooth) The biggest requirement other than Bluetooth is the need to create good interfaces and module programming so its easy to maintain the whole solution, other than that I would like to use C# but its not a real requirement, but if the difference between 2 platforms is very small then it might tip the scale. Mono (MonoTouch, Mono for android) PhoneGap RhoMobile From my understanding then PhoneGap is not suited for business apps and I am not entirely sure why, but it seems like a platform made for speed rather than long term developement, not sure how true this is. RhoMobile is made for enterprice and might suit my needs, but not sure if its a good platform Anyone with insight that care to share their opinion Mono is C#, seems to be very mature and I found MvvmCross which should help organize the project

• Is there any new method for link-backs [on hold]

  - by Mir Hammad

  As all SEOs know that google is trying its very best to kill SEO and linkbacks are quite a difficult task now. Although content is the key but my boss is still possessed with linkbacks. I can not do directory posting, link exchange, paid linking, web 2.0 and blog commenting as they are spam now. I do not see what other choice i have except forum posting and article posting. Can someone suggest new method to acquire link backs ? I know almost all traditional methods so don't say press release or etc. If you really have something out of the box or not very much common please share.

• SQLite with two python processes accessing it: one reading, one writing

  - by BBnyc

  I'm developing a small system with two components: one polls data from an internet resource and translates it into sql data to persist it locally; the second one reads that sql data from the local instance and serves it via json and a restful api. I was originally planning to persist the data with postgresql, but because the application will have a very low-volume of data to store and traffic to serve, I thought that was overkill. Is SQLite up to the job? I love the idea of the small footprint and no need to maintain yet another sql server for this one task, but am concerned about concurrency. It seems that with write ahead logging enabled, concurrently reading and writing a SQLite database can happen without locking either process out of the database. Can a single SQLite instance sustain two concurrent processes accessing it, if only one reads and the other writes? I started writing the code but was wondering if this is a misapplication of SQLite.

• How much to charge Ruby on Rails Website [closed]

  - by eWizardII

  I figured it be appropriate to ask this question on webmasters, over the stackoverflow site seeing as there are similar questions here. I am freelancing for a client in the Boston area, who has the html/css templates for their site made by another web designer. They are basically looking for someone to set up the template, and then make the backend so that a user can purchase music on their site (they are musicians). I am wondering then what would be an appropriate amount to charge them to develop such a system, I am a student, and this would be my 3rd Ruby on Rails project, but probably at least the 20 web design project I have been hired to do and I have other programming knowledge, Python, C, etc. I am thinking of suggesting that they pay 1000usd to set up such a system, but I don't know if this is appropriate. To me it seems justifiable given my experience, and the low end of RoR developers I have seen charging 25usd/hr all the way up to 150usd/hr. Any advice would be appreciated.

• Resources on learning to program in machine code?

  - by AceofSpades

  I'm a student, fresh into programming and loving it, from Java to C++ and down to C. I moved backwards to the barebones and thought to go further down to Assembly. But, to my surprise, a lot of people said it's not as fast as C and there is no use. They suggested learning either how to program a kernel or writing a C compiler. My dream is to learn to program in binary (machine code) or maybe program bare metal (program micro-controller physically) or write bios or boot loaders or something of that nature. The only possible thing I heard after so much research is that a hex editor is the closest thing to machine language I could find in this age and era. Are there other things I'm unaware of? Are there any resources to learn to program in machine code? Preferably on a 8-bit micro-controller/microprocessor. This question is similar to mine, but I'm interested in practical learning first and then understanding the theory.

• LWJGL - OpenGL - Texture shading

  - by Trixmix

  I want to use LWJGL to create a shader that all it does is change the color of the given texture. For example I tell it to draw the letter A using a sprite sheet then I can tell the shader to draw the letter in a certain color. How would you do something like this without needed to create different colored letter sprite sheets? Task for the shader: Simply change all pixels to a certain color in the texture. Input: Color , texture. Output: it draws onto the screen the new colored texture. How do i accomplish such a thing?

• Can non-IT people learn and take advantage of regular expressions? [closed]

  - by user1598390

  Often times, not-IT people has to deal with massive text data, clean it, filter it, modify it. Often times normal office tools like Excel lack the tools to make complex search and replace operations on text. Could this people benefit from regexps ? Can regexp be taught to them ? Are regular expressions the exclusive domain of programmers and unix/linux technicians ? Can they be learned by non-IT people, given regexps are not a programming language? Is this a valid or achievable goal to make some users regexp-literate through appopriate training ? Have you have any experiences on this issue? and if so, have it been successful ?

• Checker AI in visual basic not working [on hold]

  - by Eugene Galkine

  I am trying to a make checkers in visual basic with ai. I am using the minimax algorithm (or at least what I understand of it) and it works, except the ai is retarded and plays like it is trying to loose and I tried to switch around the min and the max but the results are IDENTICAL. I am pissed of and have been trying to fix it for over a week now, I would really appreciate it if someone could help me out here. I have 3 years experience of programming (in Java, only about of month of VB experience) and I always am able to solve all my errors on my own so I don't know why I can't get this to work. The program is not at all optimized or anything at this point and is over 1.2K lines long, so here is the entire vb project instead: https://www.dropbox.com/sh/evii0jendn93ir2/9fntwH2dNW I would really appreciate any help I could get.

• I'm a CS student, and honestly I don't understand Knuth's books..

  - by Raymond Ho

  I stumbled this quote from Bill Gates: "You should definitely send me a resume if you can read the whole thing." He was talking about The Art of Programming books.. So I was pretty curious and want to read it all but honestly, I don't understand it at all.. I'm really not that highly intellectual being.. So this should be the reason why I can't understand it, but I am eager to learn.. I'm currently reading volume 1 about fundamental algo.. So is there any books out there that are friendly to novice/slow people like me? So I can build up myself and hopefully in the future I can read Knuth's book at ease..

• What You Said: How You Monitor Your Computer

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your computer monitoring tips and tricks, now we’re back to share the wealth. Read on to see how your fellow reader monitor their gear. One of the more popular monitoring tools, thanks in part to the amount of things beyond just hardware it can monitor, in the comments was Rainmeter. Lee writes: I don’t really monitor my computer constantly, only when something is hanging up and I need to see what’s causing it. That being said, I do have Rainmeter so I can quickly see how much RAM or CPU is being used. For anything more detailed, I just go into the task manager and sort by RAM or CPU.

• How do I generate terrain like that of Scorched Earth?

  - by alex

  Hi, I'm a web developer and I am keen to start writing my own games. For familiarity, I've chosen JavaScript and canvas element for now. I want to generate some terrain like that in Scorched Earth. My first attempt made me realise I couldn't just randomise the y value; there had to be some sanity in the peaks and troughs. I have Googled around a bit, but either I can't find something simple enough for me or I am using the wrong keywords. Can you please show me what sort of algorithm I would use to generate something in the example, keeping in mind that I am completely new to games programming (since making Breakout in 2003 with Visual Basic anyway)?

• Distance between two 3D objects' faces

  - by Arthur Gibraltar

  I'm really newbie on programming and I'm making some tests. I couldn't find nowhere on Internet how could I calculate the distance between two 3D objects' faces. Is there anyway? Detailing, as an example, I have two 3D cubes. Each one has a vector3 position designating it's center on the 3D space and an orientation matrix. And each cube has a size (float width, float height and float length). I could get a simple distance between them by calling Vector3.Distance(), but it doesn't consider its sizes, just the position. Then the distance would be between its centers. Is there any way to calculate the distance between the faces? Thanks for any reply.

• Clonezilla failing as soon as image copying begins

  - by mmr

  I have been trying unsuccessfully to create an image of an Ubuntu 10.04 laptop system. As soon as the copying itself starts, the entire system crashes to a black screen. I suspect that the problem is overheating, and that's why I put an ice pack under the machine. That seems to have helped a bit, but it's still not getting through the copying process. Is there any other possible explanation for dying to a black screen like this? I'm just not relishing the task of removing the hard drive, mounting it elsewhere, and then doing a backup that way.

• Replace Libre Office with Microsoft Office

  - by user26272

  folks. I finally convinced my sister to drop Windows at her small business and go Ubuntu. She complained, though, that she does not want to use Libre Office and is willing to use Microsoft Office instead. I was like, ok, then. Then, she asked: - Libre office is the default, right? - Right. - So, if someone gives me a document, by default it will open on Libre Office. Can you make it open on Microsoft Office by default instead? So, even if I get it working via Wine, can I do what she requested or is it an impossible task?

• What is a good use case for scala?

  - by Usman Ismail

  In a current project we have setup the build so that we could mix Java and Scala. I would like to use more Scala in our code base to make the code more readable and concise. In the process also learn the language by handing over real features. So I plan to use Scala for some classes to showcase its benefits and convince other devs to look into using Scala too. For a rest based web server or a program in general what kind of code structures lend themselves to Scala's functional programming style.

• Preventing RSI (Repetitive Strain Injuries)

  - by nightcracker

  I am 16 years old and I love to program and playing the piano. It's not uncommon that I'm bashing away on my mouse and keyboard all day long. I do not feel any pains doing so. Yet I am still worried, because I often hear from people that they can never type for longer then 10 minutes again without getting severe pains. Given my two hobbies, programming and playing the piano that worries me a lot. My current situation is this: G15 keyboard and G5 mouse A chair that looks like this (the back of the chair is surprisingly supportive): http://www.ikea.com/nl/nl/images/products/torbjorn-bureaustoel__0084333_PE210956_S4.JPG In my "normal sitting position" the table is around the height of my bellybutton. A LG Flatron L194wt screen (too small IMO, getting a new one soon) Should I be worrying about RSI/similar health issues? If yes, what can/should I do about it?
