• How can I send audio input as chunked HTTP?

  - by Noli

  I am trying to create an interface with an external server, and don't know where to start. I would need to take audio as input to my computer, and send it to the remote server as a chunked HTTP request. The api that i'm trying to connect to is described here p1-5 http://dragonmobile.nuancemobiledeveloper.com/public/Help/HttpInterface/HTTP_Services_for_NDEV_v1.2_Silver_Version.pdf I have never worked with audio programmatically, so don't know what would be the most straighforward way to go about this? Are there solutions that exist out there that already do this? I've come across references to Shoutcast, VLC, Icecast, FFMPeg, Darkice, but I don't know if those are appropriate for what I'm trying to accomplish or not. Would appreciate any guidance, Thanks

• How can I break out of ssh when it locks?

  - by Wayne Werner

  Hi, I frequently ssh into my box at home from school, but usually when I change classes and my computer suspends, the pipe will be broken. However, ssh simply locks up - ^c, ^z and ^d have no effect. It's annoying to have to restart my terminal, and even more annoying to have to close and re-create a new screen window. So my question, is there an easy way to make ssh die properly (i.e. when the pipe fails "normally" it will exit with a message about a broken pipe)? Or do I have to figure out what the PID is and manually kill it? Thanks!

• Rosegarden don't work

  - by Brallan Aguilar

  I recently installed Rosegarden. When it had ran for the first time, it worked excellent. After, I had to restart my computer and when I ran it for the second time, something strange was occurred: according to the System Monitor, Rosegarden was running, in spite of I couldn't see the application, sometimes it's opened at other desktop and also Unity always has some instability problems like disappear the title bar of other programs or a zone is marked (for example, when we drag a window to the right side, we can see an "orange" area and the window's size is reduced to distribute at the middle of the desktop) at the left side of the screen and isn't hidden.

• Learning Python is good?

  - by user15220

  Recently I have seen some videos from MIT on computer programming topics. I found it's really worth watching. Especially the concepts of algorithms and fundamental stuffs. The programs were written and explained in Python. I never had looked into this language before as I learned and doing stuffs with C/C++ programming. But the cleanliness and better readability of syntax attracted me. Of course as a C++ programmer for long time it's the most readable language for me. Also I heard Python library contains solid algorithms and data-structures implementations. Can you share your experience in this language?

• How To Access the Developer Options Menu and Enable USB Debugging on Android 4.2

  - by Chris Hoffman

  In Android 4.2, the Developer Options menu and USB Debugging option have been hidden. If you need to enable USB Debugging, you can access the Developer Options menu with a quick trick. The developer options aren’t just used by developers. USB Debugging is required by adb, which is used for rooting an Android device, backing it up, installing a custom ROM, taking screenshots from a computer, or doing many other things.

• How do I resolve "No JSON object could be decoded" on mythbuntu live CD?

  - by Neil

  I have been running a MythTV frontend on my laptop for some time against a MythTV backend installed in Linux Mint 12 on another computer, and everything works fine. Now, I'm trying out the Mythbuntu Live CD (12.04.1 32-bit) on the laptop, to turn it into a dedicated front end. It's connecting to the network just fine, and I can see my server. When I click on the frontend icon on the desktop, it asks me for the security code, which I've verified against mythtv-setup on the server. However, when I test that code, it shows the error message "No JSON object could be decoded". I've looked in the control center to see if there's something else I should be setting up. The message above implies to me that it can't find the server, but I can find no place in the control center to tell it where to find my myth backend, which I find a little odd. Does the live CD not work against a backend server on another machine?

• How to update a game off a database

  - by James Clifton

  I am currently writing a sports strategy management game (cricket) in PHP, with a MYSQL database, and I have come across one stumbling block - how do I update games where neither player is online? Cricket is a game played between two players, and when they (or one of them) is online then everything is fine; but what if neither player is online? This occurs when championship games are played, and these games need to happen at certain times for game reasons. At the moment I have a private web page that updates every 5 seconds, and each time it loads all games are updated; but then I have the problem that when my private web page stops (for example my computer crashes or my web browser plays up) the game stops updating! Any suggestions?

• What are unique aspects of a software Lifecycle of an attack/tool on a software vulnerability?

  - by David Kaczynski

  At my local university, there is a small student computing club of about 20 students. The club has several small teams with specific areas of focus, such as mobile development, robotics, game development, and hacking / security. I am introducing some basic agile development concepts to a couple of the teams, such as user stories, estimating complexity of tasks, and continuous integration for version control and automated builds/testing. I am familiar with some basic development life-cycles, such as waterfall, spiral, RUP, agile, etc., but I am wondering if there is such a thing as a software development life-cycle for hacking / breaching security. Surely, hackers are writing computer code, but what is the life-cycle of that code? I don't think that they would be too concerned with maintenance, as once the breach has been found and patched, the code that exploited that breach is useless. I imagine the life-cycle would be something like: Find gap in security Exploit gap in security Procure payload Utilize payload What kind of differences (if any) are there for the development life-cycle of software when the purpose of the product is to breach security?

• How To Create a Portable USB Version of Microsoft Office Starter 2010

  - by Taylor Gibb

  Microsoft Office 2010 Starter edition is a free, ad-supported version of Office 2010 meant to be included on new PCs. It only includes Word and Excel with a subset of features—but it does let you make a portable version. Here’s how to do it. Note: The download link provided in the following article is not exactly a “Microsoft Approved” link and may stop working at any time. Still, the Starter version of Office is meant to be ad-supported freeware, and they haven’t pulled the download despite widespread use of it online.

• Changing permissions on serial port

  - by Terrik

  I'm using the Arduino IDE in Ubuntu, and am having issues with the serial port. It has worked in the past, but for reasons that may be unnecesary, I felt the need to change the ownership of some of the files from root ownership to my users ownership. This made the IDE work correctly, but I lost the ability to use the correct serial port. In the dev folder, the port I need is listed as permission 166. Someone (who is no longer in the area to help me) swapped the permissions to 666, which made it all work gloriously. However, it reverted back as soon as I restarted my computer, and if I now try to use the command: sudo chmod 666 ttyACM0 nothing happens. No error messages, but no permission change either. How can I change it, and how can I get it to change permanently. I apologize if this question is overly simplistic or unclear, I'm an ubuntu noob, and I wouldn't begrudge feedback!

  Getting a new drive is always exiting, but having 6 or 7 drives show up in My Computer isnt always ideal. Using this trick you can make your drives appear as folders on a another drive.

• Can't decide between Java or Python for college [on hold]

  - by Will Harrison

  I'm returning to college in about a month for Computer Science. My problem is, I have been programming on the web since I left (4 years ago), using PHP, ASP.NET, and JavaScript. I want to bone up on a more general purpose language that is cross platform before I begin. I would also like to be using a language that is common at my school and I know that they teach the students C++, Java, and Python. I would like to choose between Java or Python but I'm not sure which one. What do you think would be better based on job prospects in the next 2 years and community?

• Moving around/avoiding obstacles

  - by János Harsányi

  I would like to write a "game", where you can place an obstacle (red), and then the black dot tries to avoid it, and get to the green target. I'm using a very easy way to avoid it, if the black dot is close to the red, it changes its direction, and moves for a while, then it moves forward to the green point. How could I create a "smooth" path for the computer controlled "player"? Edit: Not the smoothness is the main point, but to avoid the red blocking "wall" and not to crash into it and then avoid it. How could I implement some path finding algorithm if I just have basically 3 points? (And what would it make the things much more complicated, if you could place multiple obstacles?)

• How to add menu items in System menu

  - by Leonardo Montenegro

  I want to insert an item to System menu: Help and Support About Gnome About Ubuntu More specifically, I want to insert a new item under "About Ubuntu". Trying with alacarte doesn't work. Cloning "ubuntu-about.desktop" file and changing his attributes doesn't work too (I even rebooted the computer after that). Searching for categories in "/usr/share/desktop-directories" haven't worked too, and searching for "core" and "about" entries in /etc/xdc/menus neither. It isn't as easy as I thought it would be. Anyone have any suggestions?

• Typing tutor games with good playablity

  - by matt wilkie

  Are there any linux typing tutor games which are enjoyable games in their own right? I'm a computer professional, but have never learned to type properly. I also don't want my kids to pick up my bad habits! The kids are okay with TuxTyping, for a time. Something like Typing of the Dead sounds great, but is Windows only, and as far as I can tell one of a kind. I also don't want the young'uns hooked on first person shooters just yet. So are there any quality typing games for a range of ages?

• Why don't computers store decimal numbers as a second whole number?

  - by SomeKittens

  Computers have trouble storing fractional numbers where the denominator is something other than a solution to 2^x. This is because the first digit after the decimal is worth 1/2, the second 1/4 (or 1/(2^1) and 1/(2^2)) etc. Why deal with all sorts of rounding errors when the computer could have just stored the decimal part of the number as another whole number (which is therefore accurate?) The only thing I can think of is dealing with repeating decimals (in base 10), but there could have been an edge solution to that (like we currently have with infinity).

• How to use MythBuntu to send TV signal to a 2nd frontend

  - by Mark Preston

  I guess the a MythTV or MythBuntu backend acts as a "server" for the frontends. I have MythBuntu installed. It runs fine, I can tune live TV, hear the sound, etc. To get this to work, I had to config the Wired Network IP4V settings to Method: Link-Local Only. The Local Backend IP address is: 127.0.0.1 and the info (bottom of screen) says that if there is another frontend, that this IP add. must be changed. 1 - Does this mean changed to the IP address of the 2nd frontend? 2 - What "Method" do I use to make 2 or more frontends? 3 - I have an ethernet switch which currently "sees" the tv signal, sends it to the computer's ethernet port where Mythbuntu makes use of it. 4 - How do I set up the Myth to send it's output (the tv shows) to both televisions? If you know of a How-To, or website, please give the URL or identifying keywords.

• 12.10 x64 - RTL8188CE - Intermittent/Slow Internet Connection

  - by Nicholas Ryan Bowers

  I have to reset my internet connection often to get it to work. When it does work, it's definitely slower than when I'm on my Windows installation. My computer uses an RTL8188CE wireless card from Realtek. I'm running the 64-bit version of Ubuntu 12.10. Power management is not on. I've read on other sites that some people fixed the issue pertaining to this wireless card by downloading and installing the drivers from the Realtek site, but it seems as if that only helped people with 32-bit installations. Anyone have any luck with this specific wireless card?
