  • Maintaining a secure database of user logins and info?

    - by Rafe Kettler
    I want to have a login form on a charity website I am building (it's for a friend, and I'm learning on the go), and I want to know what languages/software should I learn to build databases for user logins and info? Note: it HAS to be secure and relatively simple to learn for someone with moderate programming experience. Update: I understand that CMSs offer good tools for logins etc. but I want to do this all by myself.

  • SSL encrpytion, SHA1 and SHA2

    - by Hellnar
    Hello, I am trying to implement SHA2 encryption instead SHA1. For this, I know that bit number between these two hash algorithms are different and it confuses me. How can this be achieved and at what parts do I need to make required changes. I can use any open source library from Java, Python and any other major programming language. Regards

  • Create a new output file in ant replace task

    - by Sathish
    Ant replace task does a in-place replacement without creating a new file. The below snippet replaces tokens in any of the *.xml files with the corresponding values from my.properties file. <replace dir="${projects.prj.dir}/config" replacefilterfile="${projects.prj.dir}/my.properties" includes="*.xml" summary="true"/'> I want those *.xml files that had their tokens replaced be created as *.xml.filtered (for e.g.) and still have the original *.xml. Is this possible in Ant with some smart combination of tasks and concepts ?

    - by BCS
    I found this python plugin list but thought I'd ask if anyone has any experience with anything listed there? I'm totally new to both python and dynamic programming languages if that makes any difference.

    - by rahulthewall
    Hello all, I am working with Visual Studio (2008 edition) for the first time. Used to programming in a Unix environment, I have become quite used to cscope and vim.

Thanks Rahul

  • Inheritance from static classes? why not?

    - by Sorush Rabiee
    Hi Why inheritance is not provided for static classes in C#? I know C# has a good reason for everything he implements or doesn't implement. I just wondered, what’s that “good reason” here? semantically, what would be happened if I was able to write a static class that inheritances from another static one? is this an ODD issue? or just programming?

  • What do you expect of an 'Experienced Developer'?

    - by ritu
    I have been programming for about 10 years: 7 years C++, 3 years MFC, 2 JSP/Servlets, and the last year .NET (since there was some overlap the total won't add up). The problem is now that I am looking for a new job, I don't know what the latest thing is in C++ AND Java AND .NET AND MFC and somehow at interviews I am expected to KNOW everything about these topics because I have them listed on my resume. Any suggestions?

  • Neural Network Basics

    - by Stat Onetwothree
    I'm a computer science student and for this years project, I need to create and apply a Genetic Algorithm to something. I think Neural Networks would be a good thing to apply it to, but I'm having trouble understanding them. I fully understand the concepts but none of the websites out there really explain the following which is blocking my understanding: How the decision is made for how many nodes there are. What the nodes actually represent and do. What part the weights and bias actually play in classification. Could someone please shed some light on this for me? Also, I'd really appreciate it if you have any similar ideas for what I could apply a GA to. Thanks very much! :)

  • What's the best way to mix Ruby and other languages? (Especially C++)

    - by Andy
    Hi, I'm learning Ruby, and I'm starting to play with building extensions in C. I have Programming Ruby The Pragmatic Programmers' Guide and so I can follow that for the basic nuts and bolts. What I was wondering is if there already existed some nifty frameworks/whatever to help interoperability between Ruby and other languages, with C++ being the most important for me. I've tried googling, but the results focus on language comparisons, rather than language interoperability. TIA, Andy

  • Best C# Tutorials for a newbie?

    - by N00b
    Were there any awesome C# tutorials you found that helped you learn it? Or any books that you thought were particularly successful? Any that should be avoided? UPDATE: Tons of good answers, thank you all! To clarify the earlier question, hobbyist with only light programming experience previous. Working through online tutorials currently, probably going to pick up Head First C#.

  • Values of Variables Matrix NumPy

    - by Max Mines
    I'm working on a program that determines if lines intersect. I'm using matrices to do this. I understand all the math concepts, but I'm new to Python and NumPy. I want to add my slope variables and yint variables to a new matrix. They are all floats. I can't seem to figure out the correct format for entering them. Here's an example: import numpy as np x = 2 y = 5 w = 9 z = 12 I understand that if I were to just be entering the raw numbers, it would look something like this: matr = np.matrix('2 5; 9 12') My goal, though, is to enter the variable names instead of the ints.

  • Outline to teach VB6

    - by sinDizzy
    I am in need of an outline on teaching VB6/VBA to some co-workers. The material I am pretty confident I can fill in, just need a sense of how to order the class material. Its not going to be hard core programming [nix the VB6 jokes please :) ] but do want to touch the basics. Any free outlines or even entire presentations out there that I can use? I've been looking but nothing concrete so far. thanks

  • Expanding Git SHA1 information into a checkin without archiving?

    - by Tim Lin
    Is there a way to include git commit hashes inside a file everytime I commit? I can only find out how to do this during archiving but I haven't been able to find out how to do this for every commit. I'm doing scientific programming with git as revision control, so this kind of functionality would be very helpful for reproducibility reasons (i.e., have the git hash automatically included in all result files and figures).

  • how to use use case relations - uml

    - by joao alves
    Heys guys! Im have been study UML and im trying to to design the use case diagram of a problem. Lets supose my app consists in this: Two Requesites: - create teams - create players This is the deal: A user can create a team, and after create a team he can create players for that team(not required). But in this app there are multiple users, and a user can create a team and other user can create players. The only constraint is that to create players must exist alreay a team. I research and i end up a little confuse. If i get the concepts of relations on use case diagrams right, i think i should have the folowwing two use cases: [use case - create team] <-------extends---- [use case - create player] I need opinions,Is this the proper solution? or should i have two not related use cases? Thanks in advance, and im sorry my english.

  • What is the technical skill degree of your co-workers?

    - by bonefisher
    For now it has been around 4 years that I work as developer. Most of my team mates, from their tech-skill, programming ability and code practices view, are somewhere between junior and senior. In all my previous jobs, there was a real geek who was brilliant at coding/analyzing/lead, but the others were just 'average' programmers. How would you rank your co-workers as good developers from rank 1 (best) - 5 (worst) ?

  • How do i run the Android command line tools?

    - by fordays
    I'm still pretty new to Android and programming in general, and I can't seem to get the command line tools packaged with the Android SDK to work. I'm running Mac OSX and each time I try to run layoutopt, for example, the terminal returns, *-bash: cmd: command not found * Also, is it okay to have my SDK located in the Developer directory and my android project in some unrelated directory when using these tools?

  • Live chat rooms for learning ASP.NET?

    - by pkiyan
    I have come across a couple of sites in the past where a professional programmer would charge you 50 cents per minute or so to chat with them, one on one, and they would answer any questions you have about your choice of programming language. I've been studying ASP.NET 3.5 for a couple of months now and haven't been able to find a service like this for ASP.NET. Any help? A free live chat room for .NET would be of big help too.

  • Learning OpenGL ES 1.x

    - by Kristopher Johnson
    What is the quickest way to come up to speed on OpenGL ES 1.x? Let's assume I know nothing about OpenGL (which is not entirely true, but it's been a while since I last used OpenGL). I am most interested in learning this for iPhone-related development, but I'm interested in learning how it works on other platforms as well. I've found the book OpenGL ES 2.0 Programming Guide, but I am concerned that it might not be the best approach because it focuses on 2.0 rather than 1.x. My understanding is that 2.0 is not backwards-compatible with 1.x, so I may miss out on some important concepts. Note: For answers about learning general OpenGL, see http://stackoverflow.com/questions/62540/learning-opengl Some resources I've found: http://khronos.org/opengles/1_X/ http://www.imgtec.com/powervr/insider/sdk/KhronosOpenGLES1xMBX.asp OpenGL Distilled by Paul Martz (a good refresher on OpenGL basics)

  • Create, sort, and print a list of 100 random ints in the fewest chars of code

    - by TheSoftwareJedi
    What is the least amount of code you can write to create, sort (ascending), and print a list of 100 random positive integers? By least amount of code I mean characters contained in the entire source file, so get to minifying. I'm interested in seeing the answers using any and all programming languages. Let's try to keep one answer per language, edit the previous to correct or simplify. If you can't edit, comment?

    - by meo
    I'm just programming a little function that toggles a content by fading it in and out. this.advancedSearch = function(fieldset, triggerBtn){ fieldset.hide() triggerBtn.click(function(){ fieldset.toggle(function(){ $(this).stop(false, true).fadeIn(300) }, function(){ $(this).stop(false, true).fadeIn(300) }) }) } if just I use toggle() it works, but when i insert the two functions nothing happens and no error is thrown. Is there something i have done wrong?
