• USB Audio Device Loopback Through Speakers

  - by matto1990

  I have a USB turntable which when plugged in to my ubuntu 10.10 machine appears in the audio settings as an input device (USB PnP Audio Device Analog Stereo) like a microphone. What I'd like to be able to do it to have the sound for that audio device played back through the audio output (speaker or whatever). I'm not too worried if there's a slight delay between the audio coming in and it being played out through the speakers. As far as I'm aware this is refereed to as software loopback. I can achieve exactly what I want if I open Audacity, enable software loopback and press record. Obvious this isn't ideal as I don't really want it recording what I'm playing all the time. I know this is possible because of the Audacity example however I'd like to know if there's a way to do it without it recording. I've search around for a while for a piece of software that does this, however I couldn't get anything even close. Any help would be greatly appreciated.

• The SQL Server Community

  - by AllenMWhite

  In case you weren't aware of it, I absolutely love the SQL Server community. The people I've gotten to know have amazing knowledge, and they love sharing that knowledge with anyone who wants to learn. How can you not love that? It's inspiring and humbling all at the same time. There are a number of venues where the SQL Server community comes together. I'm including Twitter , the PASS Summit , the various SQL Saturday events, SQLBits , Tech Ed , and the local user groups. Each of us takes part in...(read more)

• Software, script or a tool to automate managing which tests to run

  - by laggingreflex

  I have a batch file that lists all the test files I have and asks me which test I want to perform, like Test. [U]nit, [I]ntegration : i (user input) Integration. [A]ll, [2][U]serInteraction, [3][R]esultGeneration : u 2 User Interaction. Running "mocha integration\2userint.js" ... So essentially I have configured a batch "option" for each test file I have, which I can choose to run individually or all together. But adding and removing tests is a pain. I have to update the batch file everytime a new file is added or changed. Is there a software, script or a tool, that does this automatically, or makes it easier for me to do so? I basically need it to be aware of and ask me which file(s) I want to test. A GUI with checkboxes would be ultimate! but I'll take anything. I'm working in node.js

• Video player with good subtitle rendering

  - by Oxwivi

  Is there any way to improve the subtitle rendering capabilities of Totem? The subtitles positioning seems to be hard-coded in it and even though the style is user-customizable, it does not confirm to the formatting in subtitle data. In some scenes where writings appear, the subtitles are supposed to appear next to those along with what is being said at that moment. However, on those scenes the translations of text onscreen appears on the default subtitle area with nothing about the things being said. The correct rendering are according to the open-source Windows video player, Media Player Classic - Home Cinema. There are no Linux port as far as I'm aware. If VLC's subtitle support is the same as in Windows, it won't work for me, period. Please suggest anyway to improve subtitle rendering in Totem, other video players, or a way to port MPC-HC.

• Code review versus pair programming

  - by mericano1

  I was wondering what is the general idea about code review and pair programming. I do have my own opinion but I'd like to hear from somebody else as well. Here are a few questions, please give me your opinion even on some of the point First of all are you aware of way to measure the effectiveness of this practices? Do you think that if you pair program, code reviews are not necessary or it's still good to have them both? Do you think anybody can do code review or maybe is better done by seniors only? In terms of productivity do you think it suffers from pairing all the times or you will eventually get in back in the long run?

• Logic in Entity Components Systems

  - by aaron

  I'm making a game that uses an Entity/Component architecture basically a port of Artemis's framework to c++,the problem arises when I try to make a PlayerControllerComponent, my original idea was this. class PlayerControllerComponent: Component { public: virtual void update() = 0; }; class FpsPlayerControllerComponent: PlayerControllerComponent { public: void update() { //handle input } }; and have a system that updates PlayerControllerComponents, but I found out that the artemis framework does not look at sub-classes the way I thought it would. So all in all my question here is should I make the framework aware of subclasses or should I add a new Component like object that is used for logic.

• Is there a Visual Studio style tool/IDE?

  - by Tim

  I have been developing in the windows space with Visual Studio for a while now with work, but I have also been using Ubuntu for a while and am keen to get into some software development for linux. I should also note. I am not looking for .NET and I am aware of mono. I am also familiar with c++ development and some python, so the language isn't so much relevant as the "all in one" aspect. I was interested to know if there is a useful all in one code/debug/design(gui) IDE similar to something like Visual Studio but for linux?

• ecommerce options for 5-6 products

  - by Calum

  Hi, We're looking to develop a simple e-commerce solution to sell 5-6 products. We'd rather not have to use PayPal's buttons (buy it now!) if there's an existing alternative, but would also for budget/time constraints don't want to roll our own. Are there any small, basic ecommerce solutions available that would allow this? I did look at Foxy Cart but the monthly fee was a bit of a turn off. (I must sound extremely fussy I'm aware!) Something like Zen would just be overkill for our needs. Thanks for any suggestions.

• Securing Mobile Apps in a Bring Your Own Device World

  - by Naresh Persaud

  As more and more business users begin using their personal devices to access corporate information and resources, the number of network access requests has risen dramatically.  Access Management products and strategies that were based on an employee accessing network resources from a single desktop PC were never designed to monitor and manage an employee that is using a desktop and a laptop, a tablet, and a smartphone all from outside the corporate network, and possibly from an unsecured wireless public network. A new approach is needed to manage the types and frequency of mobile app access requests - an integrated Platform Approach to Identity and Access Management that is location and device aware, that can warn you of unusual or high risk access.  A platform that provides standard APIs so you can manage your mobile apps the same way that you manage your enterprise apps. View the slideshow below to see how the Oracle Identity Management platform can help you secure your mobile applications and data in a Bring Your Own Device World.

• Asked to make a 2d platformer [on hold]

  - by Fendorio

  I've been tasked with creating a simple 2D platformer top be put on a webpage. The game is pretty much a simple Super Mario type game. I've been playing around with C# and C++ now for a couple years, so I'm aware that Unity offers a route to making a web game but for such a simplistic project i'm afraid that using unity would be overkill... i.e. slow, nobody wants to install the web player for a game with < 5 mins playtime. Html5 canvas/JS seems to jump out at me over flash, as that seems to be being pushed out. Any suggestions on a route to take would be greatly appreciated

• Great Java EE Concurrency Write-up!

  - by reza_rahman

  As you are aware JSR-236, Concurrency Utilities for the Java EE platform, is now a candidate for addition into Java EE 7. While it is a critical enabling API it is not necessarily obvious why it is so important. This is especially true with existing features like EJB 3 @Asynchronous, Servlet 3 async and JAX-RS 2 async. On his blog DZone MVB Sander Mak does an excellent job of explaining the motivation and importance of JSR-236. Perhaps even more importantly, he discusses potential issues with the API such alignment with CDI and Java SE Fork/Join. Read the excellent write-up here!

• Are there efforts to build a collaboratively edited HTML/JS/DOM reference?

  - by Pekka

  W3Schools has a reputation of being incomplete, sometimes incorrect, and ridden with advertising; still, when looking to look up some things or link to documentation when answering a SO question, it still is the only handy cross-browser resource. There are other resources like the Mozilla Developer Network that is doing an increasingly great job documenting JavaScript, and the legendary and great Quirksmode. But they, as brilliant as they are, cover only parts of the areas I am talking about, and provide no community editing and quality control options. Is anybody aware of efforts to create a collaboratively edited, cross-browser HTML/CSS/JavaScript/DOM encyclopedia? If you will, I'm thinking of a challenger to W3Schools like SO was to Experts Exchange. (I thought this more suitable on Programmers than on SO proper - please correct me if I'm wrong.)

• Dynamic tests with mstest and T4

  - by Victor Hurdugaci

  If you used mstest and NUnit you might be aware of the fact that the former doesn't support dynamic, data driven test cases. For example, the following scenario cannot be achieved with the out-of-box mstest: given a dataset, create distinct test cases for each entry in it, using a predefined generic test case. The best result that can be achieved using mstest is a single testcase that will iterate through the dataset. There is one disadvantage: if the test fails for one entry in the dataset, the whole test case fails. So, in order to overcome the previously mentioned limitation, I decided to create a text template that will generate the test cases for me. As an example, I will write some tests for an integer multiplication function that has 2 bugs in it: Read more >> [Cross post from victorhurdugaci.com]

• What algorithm(s) can be used to achieve reasonably good next word prediction?

  - by yati sagade

  What is a good way of implementing "next-word prediction"? For example, the user types "I am" and the system suggests "a" and "not" (or possibly others) as the next word. I am aware of a method that uses Markov Chains and some training text(obviously) to more or less achieve this. But I read somewhere that this method is very restrictive and applies to very simple cases. I understand basics of neural networks and genetic algorithms(though have never used them in a serious project) and maybe they could be of some help. I wonder if there are any algorithms that, given appropriate training text(e.g., newspaper articles, and the user's own typing) can come up with reasonably appropriate suggestions for the next word. If not (links to)algorithms, general high-level methods to attack this problem are welcome.

• Why using the word "mechanism" in CS?

  - by Nick Rosencrantz

  I'm not sure about the usage of the word "mechanism" when in fact most of the time what is meant is an algorithm. For instance there's talk about Java's "thread-scheduling mechanism" - why not call it an algorithm and why borrow a term from mechanics where relations sometimes are the opposites than of computer science? I'm aware that an algorithm is considered a "mechanical solution" but is this really the case in fact when a lot of algorithm don't have mechanical representations for instance a file-sharing network that gets quicker and faster as the usage grows, that would be the reverse of a mechanical structure that would go slower when usage grows.

• Any board-like platform but only for files instead of text posts? [on hold]

  - by Janwillhaus

  I am looking for a (best open-source or free but also commercially available) CMS platform that is built similarly to bulletin boards (for example phpBB) but instead of text posts, registered users can upload files that can be rated, commented etc.) I am aware of the number of board CMSes that have file-database plugins, but that is not what I want. I want to have a system that focuses on the files rather than on the postings. Or do you have any alternative ideas on solutions to the problem? I need the following functions CMS focused on file management Files that can be categorized (in a tree-like view for example) Comments and ratings can be added to files Users that can be provided various rights around the platform (moderation, commenting, exclusion of non-registered users, etc.) Users can upload files themselves (for further moderation

• Does C# give you "less rope to hang yourself" than C++?

  - by user115232

  Joel Spolsky characterized C++ as "enough rope to hang yourself". Actually, he was summarizing "Effective C++" by Scott Meyers: It's a book that basically says, C++ is enough rope to hang yourself, and then a couple of extra miles of rope, and then a couple of suicide pills that are disguised as M&Ms... I don't have a copy of the book, but there are indications that much of the book relates to pitfalls of managing memory which seem like would be rendered moot in C# because the runtime manages those issues for you. Here are my questions: Does C# avoid pitfalls that are avoided in C++ only by careful programming? If so, to what degree and how are they avoided? Are there new, different pitfalls in C# that a new C# programmer should be aware of? If so, why couldn't they be avoided by the design of C#?

• A bacon- (and module-) saving PowerShell incident

  - by AaronBertrand

  Earlier today I made a big goof. I opened a module in Notepad, intending to use it as the basis for a new module. I was in the process of using "File > Save As" when my phone rang just at the precise instant that, for some reason, made me click on "File > Save" by mistake. After hitting Ctrl+Z 30 times to try to get the old version of the module back, I remembered that Notepad has never had more than one level of Undo. Back when I was coding ASP by hand, I was very well aware of this, but I...(read more)

• `xcalib -i -a` controls only one of two screens - can it control both?

  - by drevicko

  I am using 2 screens, and wish to invert the colors on both of them without using compiz (I'm using gnome shell). I can use xcalib -invert -alter as suggested in this question, but it only inverts one of the screens. Is there a way to specify both of them, or even which of them, using xcalib? Is there another way? With xcalib, you can specify which screen to alter with the -d (-display) or -s (-screen) options, but alas, X seems to be aware of just one screen: when I use the w command I only see one (the usual ":0") ps: this question was originally posted by k0pernikus as a comment here.

• Removing mdadm array and converting to regular disks while preserving data

  - by Jeffrey Kevin Pry

  I have a 6 disk (2TB each) mdadm RAID 5 volume created in Ubuntu 12.04 Server. However, I'm moving to a different solution and want to "unraid" my disks but keep the data. Only 50% is in use. From what I can surmise I basically have to do this recursively for each physical disk. Fail the disk Format the failed disk Move a portion of files to the new disk. Reshape the array Shrink the logical volume md0 This seems like a very time consuming process. Is there an easier way to do this (automatically perhaps) without buying new disks to temporarily hold the data? I am also aware that during this processing my RAID volume will be degraded and vulnerable the entire time. I am not too concerned about this and will be using battery backup and moving the most important files off first. Thank you for your help!

• How to migrate from Banshee to Rhythmbox?

  - by rafalcieslak

  As it has been decided, Ubuntu Precise 12.04 will feature Rhythmbox as the default music player. I am aware, that it does not mean that I will not be able to use Banshee, nevertheless I would like to switch to it. I have been a Rhythmbox fan for a long time, but after the switch to Banshee in Natty I decided to give it a try and completely migrated to it. However, I am not very happy with it, it lags for me a lot and has some other issues. I would like to export all Banshee data to Rhythmbox. That includes: Music library Playlists Preferably playcounts and ratings Radio stations Cover pictures What should I do to move all this data to Rhythmbox, get it to work as the default music player, and smoothly switch completely to it?

• J2ME character animation with multiple sprite sheets

  - by Alex

  I'm working on a J2ME game and I want to have walking animations. Each direction of walking has a separate sprite sheet (i.e. one for walking up, one for walking right etc), I also have a static idle image for each direction held together in a single file. I've tried to hold an array of sprites in my player class and then just drawing the sprite corresponding to the current direction, but this doesn't seem to work. I'm aware that if I combine all the animations into one sprite sheet I could set up different animation sequences, but I want to be able to do it with separate images for each animation. Is there a way that anyone knows of to achieve this? And ideally without too much extra code (as opposed to combining the sprites into one sheet)

• Setting up Developers Conference

  - by Darknight

  In our local city in the UK, there are as far as I am aware no developer conferences. I am confident that our region has many professional developers as well as many graduating students whom who really benefit from a conference. I would like to ask the following questions: What steps or advice would one take if the task was given to set up a local developers conference? What would the costing look like? (excluding building/hosting of website(s)) How would one build interest and promote this? How would I approach, Local Companies & Universities to collaborate with them? I'm not just aiming this question to users who may have experience in setting up such conferences (but are highly welcome). Rather how would you attack this if you was tasked with this?
