  • What would be a good set of first programming problems that would help a non-CS graduate to learn programming ?

    - by shan23
    I'm looking at helping a friend learn programming (I'm NOT asking about the ideal first language to learn programming in). She's had a predominantly mathematical background (majoring in Maths for both her undergrads and graduate degree), and has had some rudimentary exposure to programming before (in the form of Matlab simulations/matrix operations in C etc) - but has never been required to design/execute complex projects. She is primarily interested in learning C/C++ - so, with respect to her background, what would be a set of suitable problems that would both engage her interest ?

  • Are there any formal approaches for familiarising oneself with a new or legacy codebase? [closed]

    - by codecowboy
    Possible Duplicate: How do you dive into large code bases? As a contractor, I often encounter legacy codebases which might have little or no supporting documentation. Are there any techniques or best practices? I work with PHP and web applications, though also face situations in which I have to edit code in an unfamiliar language. How can I leave a codebase in better shape, learn something along the way and impress the team I'm working with?

  • How to reduce MDX code redundancy in SQL Server Analysis Services (SSAS)

    To query an Analysis Services cube, MDX is used as the query language. In most business settings, one would find a set of queries that are common across a number of user query requirements. To cater to this, even with a modest size IT team, there is a good chance that the same queries are developed redundantly either within a SSAS MDX script or repetitively in an ad-hoc manner in client applications. In this tip we would look at how to reuse queries without redeveloping them over and over.

  • How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad

    - by The Geek
    The iWork apps are some of the best apps on the iPad, and each show just how powerful a touchscreen device can be with the most basic of computing functions. In fact, there’s not much to dislike about the iWork apps, except for one thing: importing and exporting files. You can open documents from email attachments, download them from websites, or import them from other apps like Dropbox. Once you’ve opened your file in Pages, Keynote, or Numbers on iPad, though, you can only send it via email, upload it to a WebDAV server or Apple’s iDisk service, or wait to sync it with iTunes on your computer. Most other iOS office apps don’t offer nearly as many features as the iWork apps, but they do offer deep integration with Dropbox which makes it easy to view and edit your documents no matter where you are. Dropbox is the most popular file sync and sharing solution, and makes it absolutely painless to share folders with anyone around the world and keep your computers in sync. That is, computers and applications that integrate with Dropbox. However, you don’t need to give up on using Dropbox with iWork apps on iPad. Today we’re going to look at how you can enable WebDAV compatibility on your Dropbox account to let Pages integrate nearly the whole way with Dropbox. It’s not a perfect solution, but it’s much better than the default setup. So let’s get started Latest Features How-To Geek ETC How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad RGB?

  • Linux is not an operating system, or is it?

    <b>Technology & Life Integration:</b> "There is a word in the English language (which I hope I am using) called context. In other words, I use the word Linux in the context of a complete Linux based distribution and believe that my readers understand that context."

  • How is a switch statement better than a series of if statements? [closed]

    - by user1276078
    Possible Duplicate: Should I use switch statements or long if…else chains? I'm working on a small program that will conduct an Insertion Sort. A number will be inputted through the keyboard and stored in a variable I called "num." I've decided to use a switch statement in order to obtain the number inputted. switch( e.getKeyCode() ) { case KeyEvent.VK_0: num = 0; break; case KeyEvent.VK_1: num = 1; break; case KeyEvent.VK_2: num = 2; break; case KeyEvent.VK_3: num = 3; break; case KeyEvent.VK_4: num = 4; break; case KeyEvent.VK_5: num = 5; break; case KeyEvent.VK_6: num = 6; break; case KeyEvent.VK_7: num = 7; break; case KeyEvent.VK_8: num = 8; break; case KeyEvent.VK_9: num = 9; break; } I realized one other course of action could have been to use a set of if statements. if( e.getKeyCode() == KeyEvent.VK_0 ) num = 0; else if( e.getKeyCode() == KeyEvent.VK_1 ) num = 1; etc. for every number up until 9. I then wondered what the essential difference is between a switch statement and a series of if statements. I know it saves space and time to write, but it's not that much. So, my question is, aside from the space, does a switch statement differ from a series of if statments in any way? Is it faster, less error-prone, etc.? This question really doesn't affect my code that much. I was just wondering. Also, this question pertains to the JAVA language, not any other programming language.

  • Finding a job: feedback on my current prodicument and my relentless efforts [closed]

    - by Michael
    I am a very well rounded IT guy, with a passion for programming in particular. I have been through a BS program less the internship as I refuse to go lower than minimum wage (i.e. free) and/or such opportunities find the institution lacking. Since then, the catalog for my degree has changed, so I am making peace without it. I go up for job interviews and get myself no farther than a submitted resume. I have even changed my strategy and made this website: http://goo.gl/qqpN8 to showcase my highlights (but not at all exhaustive) for specific areas in the US and paid for classified ads. The 'internship' is notable as I am just trying to get my foot in the door. Because IT is so vast, with programming and engineering in particular, I spend my time researching the requirements for the job I am applying for. This has made me that well rounded guy I spoke of earlier, but has made me a victim of being a jack-of-all-trades; unfortunately being a master of none. I embrace my gung-ho attitude and find it to be a trait that has powered my career before. But I am starting to lose steam. I want it straight. What is not appealing about everything I am doing? What are the technologies that I need to focus on that are in great demand at the moment?

  • How do you check out what's hot in the open source space?

    - by Fanatic23
    I am trying to look for resources (sites, magazines, blogs, twitter etc) that track what's hot and happening in the open source space. This is programming language agnostic, I am more interested in knowing what kind of cool apps people are coming up these days particularly in the enterprise and scientific computing space. I am also into compilers, debuggers and other low level stuff. Any help appreciated.

  • Why can't Java/C# implement RAII?

    - by mike30
    Question: Why can't Java/C# implement RAII? Clarification: I am aware the garbage collector is not deterministic. So with the current language features it is not possible for an object's Dispose() method to be called automatically on scope exit. But could such a deterministic feature be added? My understanding: I feel an implementation of RAII must satisfy two requirements: 1. The lifetime of a resource must be bound to a scope. 2. Implicit. The freeing of the resource must happen without an explicit statement by the programmer. Analogous to a garbage collector freeing memory without an explicit statement. The "implicitness" only needs to occur at point of use of the class. The class library creator must of course explicitly implement a destructor or Dispose() method. Java/C# satisfy point 1. In C# a resource implementing IDisposable can be bound to a "using" scope: void test() { using(Resource r = new Resource()) { r.foo(); }//resource released on scope exit } This does not satisfy point 2. The programmer must explicitly tie the object to a special "using" scope. Programmers can (and do) forget to explicitly tie the resource to a scope, creating a leak. In fact the "using" blocks are converted to try-finally-dispose() code by the compiler. It has the same explicit nature of the try-finally-dispose() pattern. Without an implicit release, the hook to a scope is syntactic sugar. void test() { //Programmer forgot (or was not aware of the need) to explicitly //bind Resource to a scope. Resource r = new Resource(); r.foo(); }//resource leaked!!! I think it is worth creating a language feature in Java/C# allowing special objects that are hooked to the stack via a smart-pointer. The feature would allow you to flag a class as scope-bound, so that it always is created with a hook to the stack. There could be a options for different for different types of smart pointers. class Resource - ScopeBound { /* class details */ void Dispose() { //free resource } } void test() { //class Resource was flagged as ScopeBound so the tie to the stack is implicit. Resource r = new Resource(); //r is a smart-pointer r.foo(); }//resource released on scope exit. I think implicitness is "worth it". Just as the implicitness of garbage collection is "worth it". Explicit using blocks are refreshing on the eyes, but offer no semantic advantage over try-finally-dispose(). Is it impractical to implement such a feature into the Java/C# languages? Could it be introduced without breaking old code?

  • What is the historical basis of using Javascript in web programming?

    - by rd108
    I come from a scientific biology background where we also use Python a lot. Now that I've begun to start with Web development, I've consistently found myself wondering just why it is that JavaScript is the primary client-side language on the Web. Is JavaScript's predominance a historical accident or something else? Also, I'm curious if there are any hurdles to integrating Python into client-side scripting?

    I removed pulseaudio today because rosetta stone had conflicts identifying the microphone which kinda makes it useless to me to learn a new language. Thing is, Alsamixer seems to have screwed up so I'm not really familiar on which configuration file I have to tweak to make the whole system use alsamixer (actually it does... but the problem is this error) $ alsamixer ALSA lib pulse.c:229:(pulse_connect) PulseAudio: Unable to connect: Connection refused cannot open mixer: Connection refused Could anyone enlighten me on which configuration file I have to change?

  • Web Hosting Checklist

    - by Chris
    I am a web developer that is starting to look into hosting his own website. I would like to showcase my programming skills (PHP, MySQl, C#, Wordpress). My knowledge of languages I am OK with but the actually hosting site is where my knowledge starts to get a little shaky. I know the basics (bandwidth, sub-domains, re-write rules) but I would love your input, to help me formulate a check list of certain web-hosting services that I should be on the look-out for. Also I was wondering if there were any reliable hosting providers who give you the option to host both c# code-behinds and PHP code. As I would like to have two versions of my site, one in C# and one in PHP the hope is that if I need to look for another job this website will help me show possible employers my server side knowledge. I hope this is enough info, I did some researching online but found a bunch of unless articles and I've always have had luck on the StackExchange sites. So hopefully you, can help me. Thanks alot.
