  • Starting off with web dev with php

    - by pavan kumar
    I'm currently working with Java / C++. I'm interested in web development and am planning to shift my stream. I heard that PHP is a good platform to start off and also it does not require that much of knowledge in technologies like JSP / Servlets or frameworks like springs / struts / hibernate. I have basic ideas about HTML and Javascript as well. I have gone through previous posts in SO and found out the relevant resources as well: http://net.tutsplus.com/tutorials/php/the-best-way-to-learn-php/ http://www.webhostingtalk.com/archive/index.php/t-1028265.html http://www.killerphp.com/ http://phpforms.net/tutorial/tutorial.html http://www.php5-tutorial.com/ etc. Now, my question is: I heard of PHP frameworks like CodeIgniter, Zend Frameworkd and Yii. Doesn't learning PHP & MySql implicitly makes us aware of these frameworks? Am I making a good choice in stating with PHP? Is it a good idea to shift streams?

  • Palm Centro not even appearing on desktop

    - by DaimyoKirby
    Background: I'm trying to set up my dad's new installation of Xubuntu 12.10 (I finally got him to switch from Windows :-D) so he can sync his Palm Centro on his computer. I installed J-Pilot, but the problem is that his palm isn't even showing up anywhere on the computer. When it's plugged in, it lit up and began to charge when I told it to try and sync with the computer, but it failed the sync and Xubuntu still doesn't recognize it. Question: Does anyone know how I can get his Palm to be recognized by Xubuntu?

  • How to customize Unity Launcher's background

    - by Luis Alvarado - The Wolverine
    In this question I do not want to customize the launcher for each workspace, or change the animations or behaviors of the icons. I only want to change how the background of the Launcher looks. Let me show you what I mean: If I do not open the Dash, the launcher looks like the following: It looks like this because I have a background that has gray, black and white colors. So Unity tries to accommodate the launcher to contrast with it. Now when I open the Dash, the launcher looks like this: What I want is to make the launcher look the same as if my Dash were open (Darker, richer background). I thought maybe to invert the colors of an opened Dash with a closed one, but that the end I do not care if the colors do change when I open the Dash, so long as the darker richer version stays. Is it possible to do this, to make the background stay with a darker color like shown in the pictures above?

  • Web Developer or Software Engineer?

    - by dahacker89
    A question that I have been asking myself and really confused which path to take. So I need your guys help as to the pros and cons of these 2 professions in today's world. I love web applications development as the Web is the best thing to happen in this age and nearly everyone gets by on the World Wide Web. And also tend to keep learning about new technologies and about web services. On the other hand I like software engineering also for the desktop applications as I have had experience with development small scale softwares in VB.Net, Java, C++, etc. Which path has more scope and better future? Whats your view?

  • unit testing variable state explicit tests in dynamically typed languages

    - by kris welsh
    I have heard that a desirable quality of unit tests is that they test for each scenario independently. I realised whilst writing tests today that when you compare a variable with another value in a statement like: assertEquals("foo", otherObject.stringFoo); You are really testing three things: The variable you are testing exists and is within scope. The variable you are testing is the expected type. The variable you are testing's value is what you expect it to be. Which to me raises the question of whether you should test for each of these implicitly so that a test fail would occur on the specific line that tests for that problem: assertTrue(stringFoo); assertTrue(stringFoo.typeOf() == "String"); assertEquals("foo", otherObject.stringFoo); For example if the variable was an integer instead of a string the test case failure would be on line 2 which would give you more feedback on what went wrong. Should you test for this kind of thing explicitly or am i overthinking this?

  • Skype, green screen, no microphone

    - by EddyThe B
    I have issues with skype using my brand new System 76 Galago Ultrapro, running Ubuntu 13.04. I installed Skype through ubuntu software centre (after allowing Canonical partner stuff), but it won't work, the video is a green screen, and it won't connect to the microphone. The webcam works when using Cheese, and the microphone appears to work in general (it shows sound levels when I go to the Input tab under the Sound settings). I tried to fix the green screen issue using this command: $ echo -e '#!bin/bash n LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so /usr/bin/skype' | sudo tee /usr/local/bin/skype sudo chmod a+x /usr/local/bin/skype as suggested here: http://debianhelp.wordpress.com/2012/09/28/to-do-list-after-installing-ubuntu-13-04-aka-raring-ringtail-operating-system/ but no luck. Any ideas? I have also asked this question to the System 76 tech support folk.

  • Beta Testing iOS Application

    - by dbramhall
    I was wondering if it is advisable to get a small team of beta testers for an iOS application that will be released to the App Store. I am developing an iOS application and I have setup a beta application form however I was wondering if it is advisable to even do beta testing considering I am actively testing and using my application on all of my own iOS devices (iPad 2, 2 iPod Touches and an iPhone 4 (plus, of course iOS Simulator)) - all running various versions of iOS 4. My question is: would you advise someone to get beta testers for an iOS application and, if so, how would you advise them to go about getting testers. For those interested, my application is at http://affogato.visioa.com/

  • Shader inputs in a general purpose engine

    - by dreta
    I'm not familiar with SDKs like Unity or UDK that much, so i can't check this offhand. Do general purpose engines allow users to create custom uniform variables? The way i see it, and the way i have implemented it in an engine i'm writing to learn 3D, is that there is a "set" of uniforms provided by the engine and if you want to write a custom shader then you utilize uniforms you need to create a wanted effect. Now, the thing is, first of all i'm not an artist, second of all, i didn't have a chance to create complex scenes yet. So my question is, is it common practice to define variables that the engine provides and only allow the user to work with what they're given? Allowing users to add custom programs and use them where they want is not hard, but i have issues imagining how you'd go about doing the same for uniforms.

  • Bug in firefox address bar autocomplete running on KDE

    - by marcus
    Has anyone experienced this graphical glitch when typing in Firefox address bar? The drop-down list is not drawn correctly, with some "blocks" missing. After typing more letters or hovering the mouse cursor, the list redraws itself and becomes complete. I'm running Ubuntu 12.04, Firefox 13.0.1 and this only happens in KDE (tested with 4.8.2, 4.8.3 and 4.8.4). It does not happen in Unity or Xfce with the same user profile. If I go to the KDE control panel and disable the Fade effect, the bug starts to happen to almost every menu in the system, including, the taskbar window previews. Enabling the “Fade” effect corrects the bug everywhere except in Firefox. I have an Nvidia card and I am using the proprietary driver (current, not current-updates -- not sure about the difference), but the linked question on an Arch Linux forum says this happen with the open source driver and with other cards too. Does anyone have an idea for a solution?

  • Level Design V.S. Modeler

    - by Ecurbed
    From what I understand being a level designer and a character/environment/object/etc Modeler are two different jobs, yet sometimes it feels like a Modeler can also do the job of the level designer. I know this also depends on the scale of the game. For small games maybe they are one and the same, but for bigger games they become two different jobs. I understand a background in some modeling could not hurt when it comes to level design, but the question I have is: Do jobs prefer people who can model for level designing? This way they can kill two birds with one stone and have someone to create the assets and design the level. What is your opinion of the training? Does level design contain skill sets that make them completely different from what a modeler can do, or is this an easy transition for a modeler to become a level designer? Can you be a bad level designer but a good modeler and vice versa?

  • College Courses through distance learning

    - by Matt
    I realize this isn't really a programming question, but didn't really know where to post this in the stackexchange and because I am a computer science major i thought id ask here. This is pretty unique to the programmer community since my degree is about 95% programming. I have 1 semester left, but i work full time. I would like to finish up in December, but to make things easier i like to take online classes whenever I can. So, my question is does anyone know of any colleges that offer distance learning courses for computer science? I have been searching around and found a few potential classes, but not sure yet. I would like to gather some classes and see what i can get approval for. Class I need: Only need one C SC 437 Geometric Algorithms C SC 445 Algorithms C SC 473 Automata Only need one C SC 452 Operating Systems C SC 453 Compilers/Systems Software While i only need of each of the above courses i still need to take two more electives. These also have to be upper 400 level classes. So i can take multiple in each category. Some other classes I can take are: CSC 447 - Green Computing CSC 425 - Computer Networking CSC 460 - Database Design CSC 466 - Computer Security I hoping to take one or two of these courses over the summer. If not, then online over the regular semester would be ok too. Any help in helping find these classes would be awesome. Maybe you went to a college that offered distance learning. Some of these classes may be considered to be graduate courses too. Descriptions are listed below if you need. Thanks! Descriptions Computer Security This is an introductory course covering the fundamentals of computer security. In particular, the course will cover basic concepts of computer security such as threat models and security policies, and will show how these concepts apply to specific areas such as communication security, software security, operating systems security, network security, web security, and hardware-based security. Computer Networking Theory and practice of computer networks, emphasizing the principles underlying the design of network software and the role of the communications system in distributed computing. Topics include routing, flow and congestion control, end-to-end protocols, and multicast. Database Design Functions of a database system. Data modeling and logical database design. Query languages and query optimization. Efficient data storage and access. Database access through standalone and web applications. Green Computing This course covers fundamental principles of energy management faced by designers of hardware, operating systems, and data centers. We will explore basic energy management option in individual components such as CPUs, network interfaces, hard drives, memory. We will further present the energy management policies at the operating system level that consider performance vs. energy saving tradeoffs. Finally we will consider large scale data centers where energy management is done at multiple layers from individual components in the system to shutting down entries subset of machines. We will also discuss energy generation and delivery and well as cooling issues in large data centers. Compilers/Systems Software Basic concepts of compilation and related systems software. Topics include lexical analysis, parsing, semantic analysis, code generation; assemblers, loaders, linkers; debuggers. Operating Systems Concepts of modern operating systems; concurrent processes; process synchronization and communication; resource allocation; kernels; deadlock; memory management; file systems. Algorithms Introduction to the design and analysis of algorithms: basic analysis techniques (asymptotics, sums, recurrences); basic design techniques (divide and conquer, dynamic programming, greedy, amortization); acquiring an algorithm repertoire (sorting, median finding, strong components, spanning trees, shortest paths, maximum flow, string matching); and handling intractability (approximation algorithms, branch and bound). Automata Introduction to models of computation (finite automata, pushdown automata, Turing machines), representations of languages (regular expressions, context-free grammars), and the basic hierarchy of languages (regular, context-free, decidable, and undecidable languages). Geometric Algorithms The study of algorithms for geometric objects, using a computational geometry approach, with an emphasis on applications for graphics, VLSI, GIS, robotics, and sensor networks. Topics may include the representation and overlaying of maps, finding nearest neighbors, solving linear programming problems, and searching geometric databases.

  • Application to display battery info

    - by Nik
    First of all, I am not sure the title of this question is the most appropriate however this is what I meant to say, There are many ways to extend the life of a laptop battery. One way is by not connecting it to the AC adapter all the time which will overcharge it. I read that in this website. Is there an application which automatically prevents the charging of the battery once it has reached 80% charged? I mean that is such a cool feature. Sometimes people tend to forget to remove the AC adapter and this could diminish the capacity and reduce the life time of the battery. Does the battery indicator in ubuntu display info or pop-up when the battery is almost dead (dead not in the sense of usage time) but rather a degraded battery?

  • Turn-based Strategy Loop

    - by Djentleman
    I'm working on a strategy game. It's turn-based and card-based (think Dominion-style), done in a client, with eventual AI in the works. I've already implemented almost all of the game logic (methods for calculations and suchlike) and I'm starting to work on the actual game loop. What is the "best" way to implement a game loop in such a game? Should I use a simple "while gameActive" loop that keeps running until gameActive is False, with sections that wait for player input? Or should it be managed through the UI with player actions determining what happens and when? Any help is appreciated. I'm doing it in Python (for now at least) to get my Python skills up a bit, although the language shouldn't matter for this question.

    - by pinaldave
    I around 10 Free Online Training Codes available of .NET and SQL Training from Pluralsight. I am willing to give it to someone who wants learn technology this weekend. You just have to go to my Facebook page and leave a comment explaining in one line – what course will you learn during weekend. I will send all this codes to 10 winners whom I will randomly select using Facebook. Meanwhile do you know how can you generate Zero without using any numbers in T-SQL. My friend Madhivanan has done that and I find it very interesting.Run following T-SQL code – ‘SELECT $’. He has written many other tricks how to generate zero also on his blog. On another note – I have published my answer for question about SELECT * vs SELECT COUNT(*) here.

  • OData where art thou?

    - by Brian
    Douglas Purdy explains. I think the best part will be the governmental aspect. All public record should be available in a way that’s easy to query IMHO. From the article: Many of us at Microsoft believe the OData protocol can help usher in a more open and programmable Web by creating a common funnel to expose rich data, thereby creating a world of customized consumer mash-ups; a world where government data is transparent and accessible to any citizen; a world where you can ask a question and know, “There’s a feed for that.” Do check out www.odata.org, and while you’re at it, check out codename Dallas. For all those government IT workers out there, consider the savings. No need to pay someone to format the data for a specific department or constituent. Just put it online and point them there.

  • Multithreaded UI desktop application issues

    - by igor
    I am involved into development a rich UI project: desktop windows application. Application uses asynchronous invocations and in its turn it should be ready to process external messages (events). The problem is clear: at first time it was built as a simple prototype and it was not stress tested and all was fine. Then application was grown: the number of calls to server and number of events from server are high and performance is low. What is more users noticed that sometimes performance is extremal low. Asynchronous invocations based on thread pool (BeginInvoke, EndInvoke), external events are going from WCF service (.NET 3.5). My goal is synchronization of all tasks and putting priorities to every executions in desktop application. My question is: is there any practice how to reach my goal: patterns, task priority list, others? What should I do at first, second and next times? Thanks

  • Mobile Apps for Hospitals?

    - by Joey Green
    I currently work for a pretty large hospital and have been dabbling in iPhone development for a couple years. The CEO is wanting to get together a group to see what mobile technology we could create. I was contacted to be the main developer. I wanted to gather some ideas of what kind of mobile apps people have seen deployed in hospitals. Not necessarily medical apps that you can get on the app store, but rather apps built specifically for a hospital. Any ideas? If this is not the appropriate forum for a question like this, can someone point me to a forum where it would be appropriate?

  • Google Places good rank on wrong keyword/category

    - by nctrnl
    I have noticed that several people find my website by searching for a completely unrelated term. This has to do with the fact that I have registered the company on Google Places with the keyword/category "webb-hotell", which in Swedish means web-hosting. If you are Swedish you may suggest using "webbhotell" instead. But the thing is that Google doesn't consider that a category, thus I get no rank at all for that keyword. It seems like I'm getting hits from people searching hotels in my area. If I type "hotel [my location]" I get a really high rank. It's not like I want people to end up on my site if they want a hotel, but it's Google's fault. My question is: What can I do about it? P.S: Can someone create the tag "google-places" for me?

  • Beginners' Guide to Development

    - by Bombillazo
    Hello. So I have some experience programming in Java, and at the moment I am learning how to use Python. I have read on the process of game design and such. I also have media covered, got experience with graphics and audio. My question is geared more towards the actual tools to use for making games, developing. I am willing to commit to a long term development cycle, as I will be doing this as a hobby. I've heard of Flash, Gamemaker, etc. I don't intend to create my own Game Engine, so I was looking for a platform that is extensible and easy to program with an OOP mind frame. As a plus it would be great of said game could be played directly from a website. TIA!

  • Scene Graph Traversing Techniques

    - by Bunkai.Satori
    Scene Graph seems to be the most effective way of representing the game world. The game world usually tends to be as large as the memory and device can handle. In contrast, the screen of the device captures only a fraction of the Game World/Scene Graph. Ideally, I wish to process(update and render) only the visible game objects/nodes on per-frame basis. My question therefore is, how to traverse the scene graph so, that I will focus only on the game notes that are in the camera frustum? How to organize data so that I can easily focus only on the scene graph nodes visible to me? What are techniques to minimize scenegraph traversal time? Is there such way as more effective traversal, or do I have to traverse whole scene graph on per-frame basis?

  • Python library for scripting (C++ integration)

    - by Edward83
    Please advise me good wrapper/library for python. I need to implement simple scripting in c++ app; Under "good" I mean pretty understandable, well documented, no memory leaking, fast. For creating base interface of GameObject on Python and C++; Your own experience and useful links will be nice!!! I found link about it, but I need more specific within gamedev context. What combinations of libraries you used for python integration into c++? For example about ogre-python it said built using Py++ and Boost.Python library And one more question, maybe someone of you know how Python was integrated into BigWorld engine (it's own port or some library)? Thank you!!!

  • Survey: How do you manage the source code for your personal projects?

    - by Linchi Shea
    This seems to be the survey season. Andy’s post on source controlling T-SQL code triggered a question that I always wanted to ask. Do you version control the source code for your various personal projects (i.e. not projects of your customer or employer)? Do you use a computer at home for your source control repository, or do you use a hosting service such as ProjectLocker ? If you do it yourself at home, what version control software you use? If you use a hosting service, what’s your experience?...(read more)

    - by karthi
    I have been asked to create a web service that communicates with Auth.NET CIM and Shipsurance API. This web service will be used by multiple applications (one a desktop and another a web application). Am confused whether to go for WCF or asmx web service . Auth.NET CIM and Shipsurance API have asmx webservices which i would be calling in my newly created web service.So is WCF the right way to Go or can i stay with asmx? Can Some one please guide. Let me know if this question is inappropriate here and needs to be moved to stackoverflow or somewhere else.
