• More complex learning source for C# .NET [closed]

  - by Leron

  By complex I don't mean more difficult but including a larger area of possibilities cover. I've started a few years ago with PHP and the transition from learning the syntax of the language and the basic logical structures to working with databases, including JavaScript and so on was very short. And now I'm more interested in studying working with languages like Java/C#. Recently I spend a lot of time reading and writing some simple console applications, I've read almost 2K pages for C# programming and still don't know how to connect to database for example. Just for info I'm interested in web development, socket programing and live streaming, don't know if I'm exceeding myself too much writing that but despite that I want to find some books/internet sources where I can extend my current knowledge of C#/.NET, start using database queries, maybe try something more complicated webwise.

• Is this a reliable method of parsing glGetShaderInfoLog()?

  - by m4ttbush

  I want to get a list of errors and their line numbers so I can display the error information differently from how it's formatted in the error string and also to show the line in the output. It looks easy enough to just parse the result of glGetShaderInfoLog(), look for ERROR:, then read the next number up to :, and then the next, and finally the error description up to the next newline. However, the OpenGL docs say: Application developers should not expect different OpenGL implementations to produce identical information logs. This makes me worry that my code may behave incorrectly on different systems. I don't need them to be identical, I just need them to follow the same format. So is there a better way to get a list of errors with the line number separate, is it safe to assume that they'll always follow the "ERROR: 0:123:" format, or is there simply no reliable way to do this?

• What should I do when Ubuntu freezes?

  - by ændrük

  All operating systems freeze sometimes, and Ubuntu is no exception. What should I do to regain control when... just one program stops responding? nothing at all responds to mouse clicks or key presses? the mouse stops moving entirely? In what order should I try various solutions before deciding to pull the power plug? What should I do when starting up Ubuntu fails? Is there a diagnostic procedure I can follow?

• In setting up dual Boot with Windows XP and Ubuntu, which OS do I install first?

  - by markl

  I'd like to install both Ubuntu 12.04 and Windows XP on a Dell laptop, and I was thinking about using a dual boot structure, and using the bulk of my hard drive as empty hard drive space to share files between the two operating systems (so choice of file system type is very important in this set-up). The kind of partitioning structure I would like to use is Partition 1 - Ubuntu 12.04 (root) (20GB) Partition 2 - Ubuntu /home (20GB) Partition 3 : Free Space (560GB) Partition 4 : Windows XP (35GB) Partition 5 : SWAP (3GB) (Total Hardrive Capacity is ~640GB) My question is; what is the best way to go about setting up this kind this system? Should I install Windows XP first and setup the partitions, and then install Ubuntu which I believe will install the GRUB bootloader for OS booting choice or Do I install Ubuntu first, setting up the available partitions and then perform a WIndows install? Please let me know if there is anything in this setup that I have left out and should know about, including things related to setting particular partitions as logical or primary, and whether the boot partition and the filesystem partition should actually be two separate partitions.

• Avoid Code Repetition in Condition Statements

  - by Ethosik

  I have been programming for over 15 years now. I consider myself a very good programmer, but I understand (like all of us) there are things that I need to work on. One of these things is code repetition when dealing with conditions. I will give a generic sample: if(condition1) { //perform some logic if(condition2) { //perform some logic if(condition3) { //Perform logic } else { //MethodA(param) } } else { //MethodA(param) } } else { //MethodA() } Now, I cannot make it easy by doing the following: if(condition1 && condition2) { } else { } I cannot do this since I need to perform some logic if condition1 is true and before I test condition2. Is there a way to structure if...else blocks to where if you need to call a method in each else blocks, you are not repeating yourself?

• Should you apply a language filter to a randomly generated string?

  - by Tim

  A while back I created a licensing system for my companies new product, as well as all products after this one. As with a lot of licensing systems mine generates codes: 25 character product and registration codes, as well as 16 character module unlocking codes. My question is, since some parts of these generated codes are random should I apply a language filter to it to avoid any embarrassing language being given to the end users? I chose to as it was not difficult at all. But has anyone else ever came across something like this? Any viewpoints as to if it is worth the effort?

• Metro-style / iPhone apps development too demanding for newbie developers? [closed]

  - by linquize

  Both Metro-style and iPhone app require approval and publishing to app store. And they focus most on user interface and the quality of the software. Developers must deal with technical aspects, such as async programming (no UI blocking), no console program (must design a UI that cope with "Standard"), no CPU hungry (pause app if deactivated), need to study the permission matrix (not full access right), and more ... A newbie is not familiar with threading and synchronization. Do you thick they are too demanding for newbie developers? Can you give more examples how demanding it is?

• How can I build this payment receipt/booking application?

  - by Festus

  I'm planning to build a payment receipt/booking application for a media company with several branches in different locations. The application should be able to move data across the network/internet to a central database where the administrator/accountant in a different location will be able to see the result of the entire job for the day from each branch. Application will run on windows environment. Will be able to send result of the booking to a Point Of Sales printer for print output. Now, I'm confused about choosing the right programming language to accomplish this task. I'm between beginner/intermediate level in PHP, I know HTML/CSS and JavaScript. I have tried to do this in PHP but, I'm face with several challenges and I fear for the POS part since PHP application run on the web browser. I don't know if python will be best suited for this and how long will it take someone with my experience level to pick up python. Any suggestion will be highly appreciated.

• Ruby on rails not popular in big international IT companies?

  - by maro

  I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

• Does low latency code sometimes have to be "ugly"?

  - by user997112

  (This is mainly aimed at those who have specific knowledge of low latency systems, to avoid people just answering with unsubstantiated opinions). Do you feel there is a trade-off between writing "nice" object orientated code and writing very fast low latency code? For instance, avoiding virtual functions in C++/the overhead of polymorphism etc- re-writing code which looks nasty, but is very fast etc? It stands to reason- who cares if it looks ugly (so long as its maintainable)- if you need speed, you need speed? I would be interested to hear from people who have worked in such areas.

• How can I stay focused and motivated on a project?

  - by RTS

  I'm working on starting my own software development business, but I've noticed that I have major issues getting projects out by their deadlines, and in general getting them out of the "almost-done" stage. I feel my problem is that I like complex programming too much, and I end up rewriting code to make it cleaner/more efficient/less error prone as a means of putting off more "boring" development. I end up with polished applications at the end, but I spend twice as long on the project as I should have. If I ever want my company to succeed, I need to work on staying focused on what actually needs to be done, so the question is: What techniques do you use to keep yourself focused and motivated on a project, in your career?

• Machine check error on ASUS while booting from USB

  - by user100453

  I put the last Ubuntu iso on my USB stick using UNetBootin, after formatting it to fat32. I've already done that before with other operating systems and it worked. I can't actually boot Ubuntu from USB since I get a black screen with the error "Machine check error" on top the an automatic reboot happens. The error appears right after the boot, I can't see anything else before. I'm using my ASUS X54L latop. Does anybody know how to solve this? Installation from CD/DVD works.

• How to make Classic ASP interesting if you are stuck with it?

  - by reno812

  I used to work on a really small outsourcing company (4 programmers and the boss), then when the stress and the frequent long shifts made the situation unbearable I made the switch to a better paid job with a more relaxed schedule that allows me some more free time. The problem, however, is that for the most part, everything is coded in Classic ASP that interfaces with a custom made C++ queueing system that stores everything in AS400 systems. My boss used to be one of the developers that made the initial efforts towards this, and naturally won't ever approve a switch to another languages / technologies despite the increasing difficulty that represents developing today business needs with yesterday tools. I'm pretty much stuck coding with Classic ASP in the foreseeable future, and I'm struggling to find ways to make it at least interesting, as I used to work with .NET and Java previously, and I feel like I'm going backwards... Any advice?

• Update Manager Partitions

  - by user170585

  Perhaps this is completely stupid, but here's my inquiry: I have Ubuntu 12.04 installed on an external hard drive. On that HD there are 4 partitions. Two for operating systems, two for swap (unnecessary but I like it that way). The actual computer itself has Windows 7. If I use the Update manager to update to 12.10 or even 13.04, would the new Ubuntu install itself on the same partition it already was on? The other operating system I'm running on the Hard Drive is Lubuntu, for when I need to run Linux on older computers, if that matters. Thanks, Adam

• Why don't we store the syntax tree instead of the source code?

  - by Calmarius

  We have a lot of programming languages. Every language is parsed and syntax checked before translated into code so an abstract syntax tree is built. We have this abstract syntax tree, why don't we store this syntax tree instead of the source code (or next to the source code)? By using an AST instead of the source code. Every programmer in a team can serialize this tree to any language, they want (with the appropriate context free grammar) and parse back to AST when they finished. So this would eliminate the debate about the coding style questions (where to put the { and }, where to put whitespace, indentation, etc.) What are the pros and cons of this approach?

• Implementing cache system in Java Web Application

  - by TGM

  I worked with JPA (Eclipselink implementation) and Hibernate. As I understand these two have great caching systems. I am interested in caching in a Web application and in order to better understand the process I'm trying to implement something on my own. Sadly, I cannot find any in depth documentation about this subject. I'm interested in things like high scalability, sharing memory on different machines and other important theoretical matters. Is there any tutorial or open project I could check out? Thank you! *LE: * I want to cache DB information in POJOs just like JPA or Eclipselink

• Matrix camera, movement concept

  - by NoFace

  I was talking to some guy. He said that my movement concept in game is bad. When left or right arrow is pressed I'm scrolling background what makes you feel that player is moving (player's X remains same). So... he told me something about matrix view. I should create all walls and platforms static and scroll only the camera and move player's rectangle. I did a little research in Google, but nothing found. Can you tell me anything about it? How to start? Maybe links, books and resources? My programming language is Java (2d). Thank you!

• Random List of numbers in C

  - by Ant

  I have just started a C programming course and so far have only done the basics like printf, read a little on variables etc on the course book. The teacher has tasked us with writing a program that will take a value entered by the user, this will be the number of students in the class (25 at the moment but can be variable). It will then list the number of students randomly and place them in 3 columns. The purpose is to sort students into groups of 3 randomly, then display on the screen in columns. Now my question is not for the code that defeats the object of me attempting the exercise, but how to structure it. I can see that using an array can be used to display the list, but really after some pointers on how best to approach the problem in blocks, then I can attempt to program each block.
