  • What should I learn after HTML and CSS?

    - by Ryan B
    I am 5 days into learning how to make my website, flying through my HTML & CSS book and having fun. I’m starting to consider what to order next. I’m not sure what to study next, so please give me some advice if you can. My end goal is to create a site that has a lot of the functionality that www.edufire.com and similar sites have, just for example. I think I’m learning well with the Head First Series, and the style will probably serve me well as an intro to programming. However, I don't think the books dive too deeply into any 1 subject. I could order: A: Head First Programming: A Learner’s Guide to Programming Using the Python Language B: Head First Javascript C: Head First PHP & MySQL D: a different programming book or E: another CSS or design book to solidify my basic HTML & CSS skills Any guidance would be appreciated. Thanks!

  • Mobile development decision - Future wise (Iphone,android,symbian)

    - by Idan
    Hi, I would like to learn mobile development, but I'm not sure which category would be the most cost effective one. I know it's kind of a prophecy question, but anyhow, suggestions would be welcomed. So, as i'm pretty familiar with C++ development , I though about learning QT. I understand that using QT, I can develop once and then deploy to symbian,Mee-go, and of course to windows, linux and more. (does that mean I won't have to lean each OS internal calls, and just learn the QT library ? ) Learning development for android , mean I will have to learn Java, which is not my preferred way of action right now. Another option is to learn Objective-C, but as it only apply to Iphone development, I think it's a pretty narrow zone for me. I want to learn a library, which would be a wise decision career wise. Any recommendations ?

  • MVC Pattern Clarification

    - by Amutha
    Just I started learning MVC pattern,ofcourse i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there) 1 ) MVC does not support server side events ,but supports client side events.if it supports client side events,i need html page with jQuery/Javascript (view),but most of the example i absorbed is to display the information(model) in view ,i did not see any client side event handling happens in view. 2) Except ViewState and controlState,MVC supports Sessions,Application State management,Cache management. 3) When request goes to MVC engine ,the routing module routes the request that is picked up by the controller.The controller in executes the appropriate action and return the appropriate view.

  • How to create an eclipse plug-in?

    - by Amir Rachum
    I've decided that as a pet project meant for learning, I would create a new Eclipse plug-in that, for a given class, takes all private member names and adds a prefix to their name (it doesn't matter to me if it can already be done or not, this is meant to be a learning experience). I have never developed an Eclipse plug-in and I'm not sure where to begin. Do I need to install some application for this development? How does it work? Where do I begin? I did a Google search but all the tutorials and results I found were old and referred to antiquated versions of Eclipse, so I'm not sure if they're still accurate.

  • how much effective is a frameworks for RIA in long run ?

    - by iamgopal
    hi , i am pretty newbie in terms of flex/RIA frameworks. mostly done work on server side. as i search on internet , people are using a lot different framework, cairngorm to mate. so my question is , as i am baby stepping through flex, should i go for learning framework ? or without framework ? ( as of now , those DI,DAO,VO and IoC doesnt make much sense to me apart from full form. ) . i needed to do pretty serious stuff after around eight month or so. should that be enough time for learning flex ? thanks in advance. ( also any link or pointers are welcome -- althogh i have spend whole my day googling around and making hello worlds...) . how to become master of RIA FLEX ?

  • Temp file that exists only in RAM?

    - by Auraomega
    I'm trying to write an encrpytion using the OTP method. In keeping with the security theories I need the plain text documents to be stored only in memory and never ever written to a physical drive. The tmpnam command appears to be what I need, but from what I can see it saves the file on the disk and not the RAM. Using C++ is there any (platform independent) method that allows a file to exist only in RAM? I would like to avoid using a RAM disk method if possible. Thanks Edit: Thanks, its more just a learning thing for me, I'm new to encryption and just working through different methods, I don't actually plan on using many of them (esspecially OTP due to doubling the original file size because of the "pad"). If I'm totally honest, I'm a Linux user so ditching Windows wouldn't be too bad, I'm looking into using RAM disks for now as FUSE seems a bit overkill for a "learning" thing.

  • GEdit/Python execution plugin?

    - by Simon Woods
    Hi I'm just starting out learning python with GEdit plus various plugins as my IDE. Visual Studio/F# has a feature which permits the highlighting on a piece of text in the code window which then, on a keypress, gets executed in the F# console. Is there a similar facility/plugin which would enable this sort of behaviour for GEdit/Python? I do have various execution type plugins (Run In Python,Better Python Console) but they don't give me this particular behaviour - or at least I'm not sure how to configure them to give me this. I find it useful because in learning python, I have some test code I want to execute particular individual lines or small segments of code (rather then a complete file) to try and understand what they are doing (and the copy/paste can get a bit tiresome) ... or perhaps there is a better way to do code exploration? Many thx Simon

  • How can I get a value out of a jQuery object?

    - by Jannis
    I am returning some data (example below) and saving it to a jQuery object (or is this an array and I am confusing the two?) when I log the variable that is the object it has the values I am looking for but how do I access the data inside this object? code $itemPosition = { 'top': $item.offset().top, 'left':$item.offset().left }, console.log($itemPosition); This would log out (the in this case expected) top: 0 & left: 490. But how can I know work with those values? Also, while this it is probably obvious I am still in the early stages of learning jQuery/Javascript rest assured that reference books are on their way, but so far the SO community has been invaluable to my learning, so thanks for reading! J.

  • Silverlight vs ASP.NET for Business?

    - by Sahat
    Which of these two technologies has bigger demand today? I have plenty of free time this summer so I was thinking of learning either ASP.NET or Silverlight 4, and get an internship this coming Fall. If you've read my other question here on SO "Financial Market Developer Dilemma" then you already know that I am planning to work in the financial industry a few years from now. So my questions are: Which technology would benefit me more in the long term: Silverlight or ASP.NET? Which one pays more $$$? Which one has higher demand? What is the learning curve like for ASP.NET and Silverlight? Thanks in advance!

  • whats the diference between train, validation and test set, in neural networks?

    - by Daniel
    Im using this library http://pastebin.com/raw.php?i=aMtVv4RZ to implement a learning agent. I have generated the train cases, but i dont know for sure what are the validation and test sets, the teacher says: 70% should be train cases, 10% will be test cases and the rest 20% should be validation cases. Thanks. edit i have this code, for training.. but i have no ideia when to stop training.. def train(self, train, validation, N=0.3, M=0.1): # N: learning rate # M: momentum factor accuracy = list() while(True): error = 0.0 for p in train: input, target = p self.update(input) error = error + self.backPropagate(target, N, M) print "validation" total = 0 for p in validation: input, target = p output = self.update(input) total += sum([abs(target - output) for target, output in zip(target, output)]) #calculates sum of absolute diference between target and output accuracy.append(total) print min(accuracy) print sum(accuracy[-5:])/5 #if i % 100 == 0: print 'error %-14f' % error if ? < ?: break

  • Getting php tips and tutorials as daily emails to improve the knowledge in php programming

    - by Sourabh
    Hi Thanks for your time. This question is related to php programming but not a programming question.I have a young team of php (LAMP + javascript) programmers.I want them to learn better coding and keep themselves updated with the latest advancements in web domain. I was thinking if there was any web site which send daily emails about php questions / problems/ solutions to common problems/ tips which will practically help the people to spend 10-15 minutes daily and enjoy the learning.This will also kind of automate the habit of self learning on daily basis. There are lots of PHP forums and php tutorials website, I tried to google but I did not find any website which does what I am looking for. Please let me know if you know such website.If you have any other ideas to achieve the goal are also welcome. -Sourabh

  • Reasons to learn MSIL

    - by mannu
    Hi, Learning MSIL is fun and all that. Understanding what is going on "under the hood" can in many ways improve how you write your code performance-wise. However, the IL that is produced by the compiler is quite verbose and does not tell the whole story since JIT will optimize away a lot of the code. I, personally, have had good use of my very basic IL understanding when I've had to make a small fix in an assembly I do not have the source code for. But, I could as well have used Reflector to generate C# code. I would like to know if you've ever had good use of MSIL understanding and/or why you think it is worth learning it (except for the fun in it, of course). I'd also like to know if you think one should not learn it and why.

  • Winforms vs WPF

    - by m0s
    I am a student and I do freelance here and there when I have opportunity. I believe my strongest language is C#. I don't really know what is going on in real programming world, so I was wondering if WPF did take over WinForms? I know the differences between two and how two can be used simultaneously but, I just don't want to invest my time in learning dying technologies, I hope you understand. So, for windows desktop programming what would you recommend to master WinForms, WPF or maybe both? I also get a lot that desktop programming is dead already and one should only care about learning web programming.

  • "ref" vs "out" keyword errors using the sql-net and C# Sqlite combination for windows phone 7.1

    - by param
    I am getting some "ref" vs "out" keyword errors using the sql-net and C# Sqlite combination for windows phone 7.1. Is this due to a wrong combination of libraries that I am using? App Type: Windows Phone 7.1 Using: 1) sql-net Version 1.0.5, Source Nuget thru Visual Studio 2) C# Sqlite for WP7 (wp7sqlite) ( Community.CSharpSqlite.WP7) Version 0.1.1, Source Nuget thru Visual Studio. The exact error I receive is below **Error 5 The best overloaded method match for Community.CsharpSqlite.Sqlite3.sqlite3_open(string, ref Community.CsharpSqlite.Sqlite3.sqlite3)' has some invalid arguments C:\Dev\Learning\SQLite.cs Line:2492 Column: 29 ** The next error then hints that it is related to the parameter being passed as "out" type instead of "ref" type. Error 6 Argument 2 must be passed with the 'ref' keyword C:\Dev\Learning\SQLite.cs Line: 2492 Column: 64 I can make the compile errors go away by replacing the "out" keyword with the "ref" keyword, but that is likely to lead to other issues. Given that I do not see much complain about this issue - I may be doing something wrong but not able to detect easily. Thanks, Parmeshwar

  • LINQ to SQL or Entities, at this point?

    - by orlon
    I'm a bit late to the game and have decided to spend some spare time learning LINQ. As an exercise, I'm going to rewrite a WebForms app in MVC 2 (which is also new to me). I managed to find a few topics regarding LINQ here (http://stackoverflow.com/questions/16322/learning-about-linq, http://stackoverflow.com/questions/8050/beginners-guide-to-linq, http://stackoverflow.com/questions/252683/is-linq-to-sql-doa), which brought the concern of Entities vs SQL to my attention. The threads are all over a year old however, and I can't seem to find any definitive information on which ORM is preferable. Is Entities more or less LINQ to SQL 2.0 at this point? Is it still more difficult to use? Is there any reason to use LINQ to SQL, or should I just jump into Entities? The applications I write at my present employer have a lengthy lifecycle (~10 years), so I'm trying to pick the best technology available.

  • Does any faster centralized version control than SVN exists?

    - by Savageman
    Hello, I've been using SVN since a long time and now we're trying on Git. I'm not talking on the centralized / decentralized debate here. My only concern is speed. The latter tool is much faster. But sometimes, I NEED to work with a centralized approach, which is much more simple and less complex than the decentralized one. The learning curve is really fast, which saves a lot of time (while digging into decentralized would lead to a waste of time, given the learning curve is much longer and we encounter more problem when working with it). However, SVN is really slow compared to GIT, and I don't think it has anything to do with the centralized argument. Decentralized systems also have to deal with server connections and file transfert. So I can easilly imagine a faster implementation of centralized version control could exists. Does someone has any clue on this?

  • Creating a video chat application for drupal site

    - by Dswabster
    I am trying to write an application for website powered by drupal, basically i would like to create an application only authenticated users are able to use, and users are only allowed to connect with members of the opposite group they are a member of. I have been learning flash builder 4 and learning the basics of actionscript but I am still pretty new to Flash and Flex development. I would like to users to connect using the Adobe Stratus 2 protocol and if possible by authentication on existing site and using membership data from existing mysql database. If anyone could give me a nudge in the right direction on how I should go about creating this application or the next steps i should take, it would be greatly appreciated.

  • feedback for programming newbies looking to build a social networking site?

    - by kgardnr
    my partner and i are launching a social learning platform - the requirements have been mapped out and are quite basic/intuitive. we are familiar with html/css, and have some very basic understanding of php, but we would love some feedback on whether we should tackle this ourselves or not. we've built websites, but in the past relied mostly on pre-fab code, i.e. wordpress, ning, etc. we've been looking specifically at ruby for developing the network, but i haven't delved into it fully yet. we're looking for some guidance and feedback - e.g. thoughts on ruby on rails? what's the learning curve? are we getting in over our heads? thanks in advance!
