  • How to reduce noise in Skype?

    - by tkc
    According to Alsamixer I do have a HDA Intel soundcard with Nvidia MCP77/78 HDMI chip (Realtek sound card on MSI notebook). When I use Skype under Ubuntu 12.04 for video calls, the other side hears background noise such as in Windows when you have your microphone boosted. In fact they can hear everything, even the fans turning on. There is nothing tweaked on Ubuntu's fresh installation. Also tried this site: https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages , but there are no *.deb files that I can test if any fix the problem. The question is if there is a way to add/tweak something to enable on software level the noise cancellation like the Windows sound drivers have that option. I use my build in mic.

  • 3D game engines for XNA games

    - by Jenko
    Before I start development of an XNA game, I need to choose a 3D game engine to develop upon. Is this belief unfounded? Does XNA have basic object transformation, lighting and mesh/texture importing functionality by which you can develop a decent 3D side-scrolling game? Chances are I'm going to need a 3D engine such as Torque X to handle most of the special effects, animation and sound for me. What are the engines that you recommend building an XNA game with? What work reliably in your experience? Is XNA alone enough? do you have repositories of code that work directly with XNA to create effects and other game environments with sunlight, fog and rain?

  • jquery slidetoggle expands and collapses straight away [migrated]

    - by Floran
    Please see here: http://www.wunderwedding.com/weddingvenues/search On the left side there's a filter 'show more cities...' When it's clicked I want to show more cities. But right now when it's clicked the box expands and IMMEDIATELY collapses again. I dont know what Im doing wrong. This is the code for show/hide: $("#toggle_cities").click(function () { if ($("#facets_city").is(":visible")) { $("#toggle_cities").text('toon meer steden...'); } else { $("#toggle_cities").text('toon minder steden...'); } $("#facets_city").slideToggle("slow"); });

  • URL parameter names being changed by user agents

    - by Mike Deck
    In reviewing one of our site's web logs I'm seeing instances where we are returning a 404 to requests because we're expecting an id parameter to be sent, but instead we're seeing a di parameter. The resource in question is an image but which image file actually gets served is dependent on the id parameter. The expected url is something like http://images.mysite.com/photo.gif?id=123&width=200&height=300 What I'm seeing in the logs is requests for http://images.mysite.com/photo.gif?di=123&width=200&height=300 The only case where we are seeing this on the id parameter. It seems unlikely that this is due to a server side or JavaScript bug since it seems to be only effecting a small percentage of our traffic. We are seeing this across a wide variety of user agents (both mobile and desktop) and IPs. Has anyone else seen this? Is there a browser plugin or other software you're aware of that could be causing this, and if so is there a good way to work around the issue?

  • i have xp partitioned and formatted fat32 it says it needs to be bootable to install ubuntu how do i do that? [duplicate]

    - by Rob Bailey
    This question already has an answer here: How do I install Ubuntu? 4 answers I have partitioned the hard drive and formatted it fat 32 as it is only 16gig. I have just read that I should not partition the hard drive so I have deleted the partition, I noticed that if i re-partition it my options would be NTFS, Fat32 or exfat. I tried to install ubuntu 12.10 but it flashed up something along the lines of the partition is not bootable and it must be for ubuntu to install. I know my copy works as a friend installed it over his copy of windows and it works perfect, I have ubuntu on my flashdrive, I want to run it along side xp.

  • How are design-by-contract and property-based testing (QuickCheck) related?

    - by Todd Owen
    Is their only similarity the fact that they are not xUnit (or more precisely, not based on enumerating specific test cases), or is it deeper than that? Property-based testing (using QuickCheck, ScalaCheck, etc) seem well-suited to a functional programming style where side-effects are avoided. On the other hand, Design by Contract (as implemented in Eiffel) is more suited to OOP languages: you can express post-conditions about the effects of methods, not just their return values. But both of them involve testing assertions that are true in general (rather than assertions that should be true for a specific test case). And both can be tested using randomly generated inputs (with QuickCheck this is the only way, whereas with Eiffel I believe it is an optional feature of the AutoTest tool). Is there an umbrella term to encompass both approaches? Or am I imagining a relationship that doesn't really exist.

  • Best strategy to discover a web service in a local network?

    - by Ucodia
    I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

  • How To Delete Your Skype Call and Chat History

    - by Gopinath
    Just like every other modern application, Skype also records all the communications we exchange using it. It records instant messages, calls, file transfers, SMS, etc. and makes it easy to view using the Conversation tab. If you ever feel like getting rid of these history information, then you need to delete them. Skype provides a single click option to clear all the history from you account, but the feature is buried deep under options menu.Really deep!. To clear history follow the menu Tools –> Options, switch to Privacy Settings tab available on the left side, click on Show advanced options button and finally hit the button Clear history. Ah! You are almost done. Just confirm a popup it displays on screen and your history is vanished from your account. Join us on Facebook to read all our stories right inside your Facebook news feed.

  • Update installed on netbook.. now sidebar icons have disappeared! :oS

    - by Lolly Collier
    hope someone can help. I am not extremely computer literate and my brother installed Ubuntu on my Acer net book when my windows crashed irretrievably . I recently (day before yesterday) had a box come up saying an update (i think it was 10 or 11 .something) i followed the instructions to download and install it and now, all my side bar icons have disappeared. I happened upon an Internet connection by chance and have no idea whatsoever how to get them back. This is quite probably a really stupid question and a really easy fix but as i said earlier, i am pretty much a novice, very far from a computer expert! Thanx in advance :o)

  • How to write loosely coupled classes in node.js

    - by lortabac
    I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

  • Education path advice

    - by Miroslav Zadravec
    I'm thinking of continuing my education and going for masters degree. I must decide between two programs. One is CS/IT and focuses on algorithms, math, multimedia, web technologies with optional interesting courses like AI and robotics. Second is about business process management, software architecture and project management. I have some experience in business software and I must say, I never though I need deeper understating of algorithms or program language but I always felt that I'm lacking in project planing or management knowledge. On the other side, CS/IT looks more interesting but what are the chances to find a job that require such skills?

  • Studying Quantum Computing?

    - by The_Neo
    Hi I am a computer science student currently on an internship and I have been thinking more and more about looking into working for a company / places that is developing quantum computers/ing when I graduate. Here is my problem, I have a pretty solid grasp of mathematics involved in Comp Sci and enjoy learning about more Comp Sci theory but in doing some minor research about Quantum Computing it seems to me to be more about hardware and I have always leant more to the software side of things. I haven't studied any physics since high school so I am wondering if I would be suitable to work in such a field with a Comp Sci degree, is it a field more aimed at physicists?

  • Getting data from a webpage in a stable and efficient way

    - by Mike Heremans
    Recently I've learned that using a regex to parse the HTML of a website to get the data you need isn't the best course of action. So my question is simple: What then, is the best / most efficient and a generally stable way to get this data? I should note that: There are no API's There is no other source where I can get the data from (no databases, feeds and such) There is no access to the source files. (Data from public websites) Let's say the data is normal text, displayed in a table in a html page I'm currently using python for my project but a language independent solution/tips would be nice. As a side question: How would you go about it when the webpage is constructed by Ajax calls?

  • Do you accept counter offers when recruiting experienced programmers? [migrated]

    - by MathAttack
    It is VERY hard to find good experienced programmers. Generally if they're performing well, their employers don't want to let them go, and many don't have resumes, let alone resumes in circulation. Let's say you find one who for personal circumstances is available. And let's say you make them an offer that's fair within your salary structure. And let's say you get a modest counter. (5-10% of the total offer side) Do you accept the counter? Part of me says, "Programmers like this are so rare, why let a small sum get in the way of hiring them?" The other part says, "This precedent will set up an annual headache." Thoughts? I know it's not black and white.

  • What options should I consider for a modern Web/Mobile development stack? [on hold]

    - by jimmy_terra
    I'm a long time server side dev who has been tasked with building a bleeding edge web UI (go figure), so apologies for the very broad nature of the question. What are the best modern libraries, tools, languages and patterns for building a dynamic web application that will run seamlessly on mobiles also? My requirements are that it must be dynamic (push updates), support automated testing, and should allow 'componentization' (a team of devs will be working on this). What should I check out and why? I will start off with some of the things I'm looking at already: Front-end HTML5 CSS3 JavaScript AngularJs Testing Karma Testem Jasmine Patterns Single Page Applications

  • Largest successful JavaScript project? [closed]

    - by 80x24 console
    A common theme in the GWT community is "I wouldn't want to build a project of THAT size using a pure JavaScript library!" What is the largest project that you have successfully delivered with frontend functionality written in JavaScript? (not Java or GWT) Please provide at least a hand-wavy SLOC estimate of the unique JS code (not including libraries, frameworks, toolkits, test code, generated code, server-side processing such as PHP, etc.) that was in the finished product. Note to GWT advocates: Please read the question carefully before answering. I've heard plenty of stories about JS failures and GWT successes, but I'd like to hear some quantified JS successes. Note to mods: This is primarily a business-of-software question, not a tools question. It factors into a real-world business decision.

  • How do I create a big multiplayer world in UDK?

    - by Dorpe
    I want to create a big multiplayer world in UDK and I'm having a few difficulties. I created the biggest terrain possible but then any terrain related action I do takes forever. However, I've seen videos of people make same size terrain and working without a problem. My pc is strong enough, so maybe someone can tell me what I'm doing wrong. I want to make it even bigger then the biggest terrain size, so I was thinking of doing level streaming but then I read that streaming is working server side which means if I have a player on every terrain all terrains will still be loaded and I want to save as much memory possible so it will work well online. Thanks for any help you can give.

  • Maximal screen resolution for external monitor breaks desktop

    - by Robiston
    Whenever I'm plugging in my external monitor into my notebook and changing the screen resolution to the maximum state, the desktop will get broken in a way: A third of the whole desktop space is not visible at all. I can see the whole panel as well as the Unity side bar to the left, but the desktop space with all the windows in it is not completely visible. It's blanked out. In case of opening the Unity menu bar, I can type something in it. As soon as close the menu bar, the upper part stays visible and hangs: Any ideas about that issue?

  • Building (simple) stellar systems

    - by space borg
    hi I'm currently looking at how to simulate easily some stellar systems (meaning some central stars and then some planets with maybe satellites), in order to allow later some space based strategy game (hence with space ships moving around). This should all be based around time (so the state of each system differs through time) I'm quite struggling with the math behind this topic, like for example: - ellipse related math, - creating the path from planet A to B having time in mind (respective positions will change over time)... Do you know of any resources for that ? I wouldn't mind even buying books about it... thanks in advance best space borg side note: how to display all this stuff isn't a matter at this point in time, I'll simple plans for that (basically sticking to 2D and a "high level view" with no space ships/planets details, just markers)

  • C# Rendering Engine for Roguelike [closed]

    - by Haedrian
    I'm trying my hand at designing a roguelike, and I need a pretty simple 2D rendering engine that works with C# Its as simple as it gets, I want to be able to drop sprites somewhere on a grid, with some sort of menus/text on the side; that sort of thing. The (very complicated) game itself would be decoupled from the interface I've looked into a number of engines and they all seem to be very complicated/support much more things than I need. Right now I'm planning on making my own using either XNA or OpenTK - but I was wondering whether anyone has any suggestions for less-complicated rendering engines which might make my job easier. Thanks.

  • How is your working time distributed between coding and thinking?

    - by mojuba
    ...in percentage. For example 60/40 or 90/10 or 100/0. My hypothesis is that the bigger the proportion of time you spend thinking the smaller your code can be as a result (and the less time will be needed to write it down). Think more, write less, in other words. Do you think it is true? As a side note, I think in typical software companies thinking is not part of the culture anyway: you are usually supposed to be sitting there at your computer typing something. You will almost definitely be noticed by your managers if you wander about with a blank look thinking over your next steps with your code. Too bad.
