  • Windows Management Using C# Programming

    Windows management has a prime place in system monitoring and administration irrespective of the technology being used. The suppleness that is achieved using the Windows management native API's are far more than that which could be achieved through other kinds of monitoring and administration application.

  • Standard/Compliance for web programming?

    - by MarkusK
    I am working with developers right now that write code the way they want and when i tell them to do it other way they respond that its just matter of preference how to do it and they have their way and i have mine. I am not talking about the formatting of code, but rather of way site is organized in classes and the way the utilize them. and the way they create functions and process forms etc. Their coding does not match my standards, but again they argue that its matter of preference and as long as goal achieved the can be different way's to do it. I agree but their way is proven to have bugs and we spend a lot of time going back and forth with them to fix all problems security or functionality, yet they still write same code no matter how many times i asked them to stop doing certain things. Now i am ready to dismiss them but friend of mine told me that he has same exact problem with freelance developers he work with. So i don't want to trade one bad apple for another. Question is is there some world wide (or at least europe and usa) accepted standard or compliance on how write secure web based applications. What application architecture should be for maintainable application. Is there are some general standard that can be used for any language ruby php or java govern security and functionality and quality of code? Or at least for PHP and MySQL i use for my website. So i can make them follow this strict standard and stop making excuses.

  • SSD harddisks & programming

    - by Carra
    SSD harddisks have been on the rise lately. And I've been wondering if it's worth buying one as a programmer. Being able to save five minutes when starting my PC is fun but won't convince my boss. How does it impact a typical visual studio project containing hundreds of files? Compile times, accessing files, waiting for visual studio to do its thing... Are there any benchmarks that checked this? And ideally, how much time would one win each week by upgrading?

  • What to bring to a programming interview? [closed]

    - by ddrum
    I have just completed my Master's degree in Computer Science and have gotten my first job interview as a developer. I do not have much experience in large scale development projects, but I am hoping my university education counts for something. I am wondering, what materials should I bring that would impress my interviewers? What do most interviewers expect, especially from a new graduate? **Edit: The job interview went OK, except I forgot my pants. Thanks for all the great advice!

  • Web programming, standard way to deal with a response that takes time to complete

    - by wobbily_col
    With normal form submission I use the pattern Post / Redirect / Get, when processing the forms. I have a database application built with Django. I want to allow the users to select a number of items from the database, then launch a computationally intensive task based on those items. I expect the task to take between 10 minutes and 2 hours to complete. Is there a standard approach to dealing with requests like this (i.e. that don't return immediately)? Ideally there would be some way to display the progress.

  • Charakter coding / programming

    - by Jery
    lately I tryed a few times to create charakters for some games, but at some certain point (especially when collision detection came in) everything became messy and the interaction between chars, the world and certain items had a lot of bugs. So here is my question, how do you ussualy keep track of actions that your charakter is allowed to do, or more in general do you have some links / advices how to set up a char efficiantly? I´m working on a char right now, who should at least be able to run, jump, pick items up and use different fighting animations. Most ideas I came up with until now use some kind of action.priority / action.duration system to determain whats possible and what not, or a "action-manager" which defines for every action what is possible from that action on but it all doesnt work that well together =\ thx in advance for some input

  • Game programming and quantity of timers

    - by andresjb
    I've made a simple 2D game engine using C# and DirectX and it's fully functional for the demo I made to test it. I have a Timer object that uses QueryPerformanceCounter and I don't know what's the better choice: use only one timer in the game loop to update everything in the game, or an independent timer in every object that needs one. My worry is that when I try to implement threads, what will happen with timers? What happens with the sync?

  • C++ game programming

    - by UnTraDe
    Until now I have been using C# with XNA for 2d and a little bit of 3d games, althought I dont remember that I finished any of them I want to start working with C++. I have a very very little exprience with C++ and my question is where to start? I plated a little bit with SFML and I encountered some problems with performance when I started to build a tile based game. I'm pretty sure that the problem is my code and not the library itself. Is there anything similiar to XNA for C++? I should keep try and work with SFML? Sorry for my bad english! Thanks in advance!

  • C# WPF to Embedded programming transition

    - by Cheltoonjr
    I've been learning C# .NET Framework for around 4-6 months (still starting) using some books, and have currently made my way up to Collections and Generics. I'll probably spend the next two months covering the rest up to LINQ and/or Garbage Collections. The thing is, I started to get interested in embedded systems and found out that you can use C# to code it through .NET MF, which mean I wouldn't have to learn C or C++. So, I would like to know if the knowledge I'll have by that time (2 months) will be enough to start working on Embedded (using C# .NET Micro Framework and Netduino) or I should probably see more about plain C# like Multithreading, async and other advanced features ? I want use embedded just as a hobby, at least by now, as I'll still have a long way through university. Although, I'll probably pick it as a career then. Thanks in advance!

  • What should I do with my programming project?

    - by rambodash
    I've been working on a top secret project that has potential of becoming very popular. No one has done anything like it. The problem is I have no motivation to finish it, and its about 70% done. I also don't have the ability to sell & market the product. The documentation is a pain to write. I just want to finish the project , receive my reward and move on to other things. I know that if I were to release it as a product I'm going to have to do support, and do bug fixes. No thank you! I've thought of making it open source but I'm failing to see the benefits. My hard work is just going to be up for grabs isn't it? How can I abandon my project whilst getting rewarded for the work I've done so far?

  • How to solve programming problems using logic? [closed]

    - by md nth
    I know these principles: Define the constrains and operations,eg constrains are the rules that you cant pass and what you want determined by the end goal, operations are actions you can do, "choices" . Buy some time by solving easy and solvable piece. Halving the difficulty by dividing the project into small goals and blocks. The more blocks you create the more hinges you have. Analogies which means : using other code blocks, yours or from other programmers . which has problem similar to the current problem. Experiments not guessing by writing "predicted end" code, in other word creating a hypothesis, about what will happen if you do this or that. Use your tools first, don't begin with a unknown code first. By making small goals you ll not get frustrated. Start from smallest problem. Are there other principles?

  • C programming multiple storage backends

    - by ahjmorton
    I am starting a side project in C which requires multiple storage backends to be driven by a particular piece of logic. These storage backends would each be linked with the decision of which one to use specified at runtime. So for example if I invoke my program with one set of parameters it will perform the operations in memory but if I change the program configuration it would write to disk. The underlying idea is that each storage backend should implement the same protocol. In other words the logic for performing operations should need to know which backend it is operating on. Currently the way I have thought to provide this indirection is to have a struct of function pointers with the logic calling these function pointers. Essentially the struct would contain all the operations needed to implement the higher level logic E.g. struct Context { void (* doPartOfDoOp)(void) int (* getResult)(void); } //logic.h void doOp(Context * context) { //bunch of stuff context->doPartOfDoOp(); } int getResult(Context * context) { //bunch of stuff return context->getResult(); } My questions is if this way of solving the problem is one a C programmer would understand? I am a Java developer by trade but enjoy using C/++. Essentially the Context struct provides an interface like level of indirection. However I would like to know if there is a more idiomatic way of achieving this.

  • Can I use POSIX signals in my Perl program to create event-driven programming?

    - by Shiftbit
    Is there any POSIX signals that I could utilize in my Perl program to create event-driven programming? Currently, I have multi-process program that is able to cross communicate but my parent thread is only able to listen to listen at one child at a time. foreach (@proc) { sysread(${$_}{'read'}, my $line, 100); #problem here chomp($line); print "Parent hears: $line\n"; } The problem is that the parent sits in a continual wait state until it receives it a signal from the first child before it can continue on. I am relying on 'pipe' for my intercommunication. My current solution is very similar to: http://stackoverflow.com/questions/2558098/how-can-i-use-pipe-to-facilitate-interprocess-communication-in-perl If possible I would like to rely on a $SIG{...} event or any non-CPAN solution. Update: As Jonathan Leffler mentioned, kill can be used to send a signal: kill USR1 = $$; # send myself a SIGUSR1 My solution will be to send a USR1 signal to my child process. This event tells the parent to listen to the particular child. child: kill USR1 => $parentPID if($customEvent); syswrite($parentPipe, $msg, $buffer); #select $parentPipe; print $parentPipe $msg; parent: $SIG{USR1} = { #get child pid? sysread($array[$pid]{'childPipe'}, $msg, $buffer); }; But how do I get my the source/child pid that signaled the parent? Have the child Identify itself in its message. What happens if two children signal USR1 at the same time?

  • Concurrent Programming:Should I write a sequential program first, then add thread safety?

    - by evthim
    I'm working on a project where we have to create a number of threads(actual number will be inputted in by testers (TA's)). I'm having trouble not only with the programming but also with the design, I can't wrap my head around all of the threads that will be invoked and where I might cause errors. The project is due soon so I don't want to waste time on this if it'll actually set me back, but I was wondering if I should write the program like only one thread will be running and everything should be sequential and then later go back and try to add the thread safety parts of the code? Would that take twice the original amount of time? Project Description: Note:I'm going to be as vague as possible so I don't violate any honor codes, sorry :( your program should accept n number of objectA threads, m number of objectB threads, and r number of objectC objectB threads interact with code in objectA. objectA threads interact with code in objectB and objectC objectB and objectC don't directly interact, but do so indirectly through objectA -ex: objectB needs something from objectA. objectA gets the result for that something by calling objectC my confusion stems mostly from the fact that all of this interactions will be done by m+n threads and there are various restrictions throughout the descriptions, like objectB can request something from objectA, and objectA has to wait for objectC to finish that something before returning it to objectB. Also each objectA thread can only work on one instruction from objectB at a time, etc. etc. I just want to know if I write the code so that there is only 1 objectA, 1 objectB and 1 object C, can I go back and easily modify it so that those 1's can be changed to m, n and r? Sorry again, if my description is a little bit confusing.

  • Should I learn two (or more) programming languages in parallel?

    - by c_maker
    I found entries on this site about learning a new programming language, however, I have not come across anything that talks about the advantages and disadvantages of learning two languages at the same time. Let's say my goal is to learn two new languages in a year. I understand that the definition of learning a new language is different for everyone and you can probably never know everything about a language. I believe in most cases the following things are enough to include the language in your resume and say that you are proficient in it (list is not in any particular order): Know its syntax so you can write a simple program in it Compare its underlying concepts with concepts of other languages Know best practices Know what libraries are available Know in what situations to use it Understand the flow of a more complex program At least know most of what you do not know I would probably look for a good book and pick an open source project for both of these languages to start with. My questions: Is it best to spend 5 months learning language#1 then 5 months learning language#2, or should you mix the two. Mixing them I mean you work on them in parallel. Should you pick two languages that are similar or different? Are there any advantages/disadvantages of let's say learning Lisp in tandem with Ruby? Is it a good idea to pick two languages with similar syntax or would it be too confusing? Please tell me what your experiences are regarding this. Does it make a difference if you are a beginner or a senior programmer?

  • Can anyone give me a sample java socket programming for doing a peer to peer for 3 systems?

    - by Sadesh Kumar N
    I am doing an university project. I need some sample programs on peer to peer programs in java socket programming. Every where people are telling to add a server socket in the client program. I am in a confusion. Can a single program having server socket and client socket will do or i have to create two programs of one initiating a system and another peer program running thrice to solve the problem. or i need to create three programs for three peer systems. I am not clear on the architecture of building peer to peer programs using java sockets. Can some one help me giving a simple program on how to create a peer to peer connection between three systems. I know how to do a socket program for client server model and clear on the concept. But creating a peer to peer architecture sounds complex for me to understand. I also referred this thread. developing peer to peer in java The person commented second says" To make peer2peer app each client opens server socket too. When client A wishes to connect to client B it just connects to its socket. " Need some more sample and an explanation on how peer to peer java socket program works I dont want any external api like jxta to do this task. I need a clear picture on how it works alone with an example.
