• Windows move onto second monitor when I turn it on

  - by user1002379

  I'm using a small monitor for my main display I also have an LCD TV hooked up through HDMI as my secondary display. The problem is whenever I turn on the TV most but usually not all of my currently running program windows jump to the secondary display. This is very annoying, because I don't like to keep my TV on unless I'm using it. So when I do turn it on I have to drag and drop each of the windows back on to my main display. I have played around with some Compiz settings to no avail please help.

• Start Programming embedded devices

  - by user1611753

  I am good at C programming and also I am good at embedded devices. I have setup an embedded circuit myself using the basic arduino and by interfacing some devices with it. But the main problem is that I do not know where and how to start programming this device with the known C programming skills. The device has an on chip boot loader. By "start programming", I mean how to bring the embedded device into my programming and stuff. I know program starts from a main() and an infinite loop makes the application run. But the real question is, how to start this all and integrate the hardware with the software which I write. Kindly help with this. Thanks for the help in advance.

• Full screen: launchbar + panel overlaps when showing a dialog box

  - by user85921

  I'm developing a program for 12.04 that will run on full-screen, so I would like to have full control of what appears on the screen. However, when I show another window (possibly a dialog/message box), the Uunity Panel and Launcher appears on the top and left side of the screen. I've experienced this behavior with other applications (Firefox, Gnubg) as well when in full-screen mode. I tried to play with the settings, now my dialog box is hidden from the the taskbar, set to float on it's parent, which is my full screen window. The problem still exists. Is there a way to prevent these panels from showing up, when the new window isn't shown in taskbar, or it's parent is a full-screen window? Or do I need to completely disable them?

• What should I do when Ubuntu freezes?

  - by ændrük

  All operating systems freeze sometimes, and Ubuntu is no exception. What should I do to regain control when... just one program stops responding? nothing at all responds to mouse clicks or key presses? the mouse stops moving entirely? In what order should I try various solutions before deciding to pull the power plug? What should I do when starting up Ubuntu fails? Is there a diagnostic procedure I can follow?

• Couldnt find a way to open blender software

  - by sapphirebox001

  I am new to Ubuntu. I downloaded the latest version of Blender (2.70a) from official blender.org site as an tar.bz2 file. My Ubuntu OS is 14.04 LTS amd64 bit os, and I am sure that I have downloaded the correct version of blender. I have read that for security reasons, Ubuntu does not allow executing exe files. Since the downloaded package contains blender as an executable/x-executable type, it is not able to execute. I do not have an internet connection in that computer too. Also the "Allow executing file as program" checkbox is checked by default. Still double clicking it does not execute the file. Can anyone say how to open this file? P.S: Wine also checked but requires active internet connection, which I dont have.

• Should we use python 2.6 or 2.7 or 3.x?

  - by lamwaiman1988

  The version of python which I am using is 2.6, and there is a 2.7 and 3.x. Usually I use python for some trivial program/snippet. I realize there are some major difference between 2.x and 3.x. I would really like to know, if I am going to make a bigger project with python, which version of python should I use? Should I upgrade to 2.7, or go to 3.x or stay with 2.6? The decision should be based on these terms: Number of user in the internet as a community. More users mean more open-source package and help from them. Functionality. Support from official development team. Compatibility for existing module/package. Thanks!

• Does Turing-complete implies possibility of malware? [closed]

  - by Mathematician82

  Is it possible to build an operating system that contains some Turing complete compiler (language?) but is unable to run any malware? Or is there any definition for a malware? This question popped on my mind as I was wondering why Windows has more malware than Linux. If Linux contains a C programming language and its compiler, I think it is possible to write a Linux program that works similarly than Windows viruses. But there are less malware for Linux than for Windows although there is a Wine for Linux to simulate Windows programs.

• optirun fails in Ubuntu 12.10

  - by chiloxsan

  I am trying to use Nvidia Optimus on my laptop by using Bumblebee, I have an Intel Core i5 with an Nvidia Geforce GT 630M. I have followed the instructions on the wiki page at https://wiki.ubuntu.com/Bumblebee, but when trying to run optirun with Firefox (or any other program, like glxspheres), I get the following error: [ 1921.452820] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver [ 1921.452905] [ERROR]Aborting because fallback start is disabled. I have tried googling the issue but I couldn't find any solution that didn't cause more problems. Thank you for your time. Here is my bumblebee.conf: http://paste.ubuntu.com/1333324/

• And just like that, there went February

  - by Enrique Lima

  The best intentions were having me at perhaps posting more than twice a month, and here we are and … well it has been busy. There has been a lot of SharePoint 2010 already in this first number of weeks of the year, a good amount of TFS 2010, but even better working quite actively on two topics that I enjoy quite a bit … Windows Azure and Application Lifecycle Management.  And there is more to come around those two. Through the influencers program with Geekswithblogs and Discountasp.net I got access to a hosted TFS solution that I am currently testing and will be posting my findings and documenting a good amount of information on that process. Another great resource has been fpweb.net, and there will be more details on this too.  Pretty exciting stuff! That is what is going on and what will be coming on here shortly.

• "Permission denied" error

  - by user1175807

  Alright so I installed Ubuntu last night and I am very new to everything. Right now I am trying to run a program called JES, (Jython Environment for Students). The instructions tell me to cd to the JES directory I have, so I type cd /home/Programs/JES It takes me to the directory I need to be in, so far so good. Then I have to type in: ./JES.sh And I get this returned to me: bash: ./JES.sh: Permission denied I have very little comprehension of what to do in Terminal or anything of the sort. Any help would be appreciated. I have tried using sudo -l to get permissions but it still persists.

• How can I fix a very broken Ubuntu installation without losing data?

  - by jredkai

  Okay guys, I was installing a program (I do not remember the name). When I did sudo apt-get update I was given missing dependencies. It told me to sudo apt-get install -f which deleted just about every dependency needed for Ubuntu, now I cannot log in or anything, now in GRUB it actually says Debian instead of Ubuntu. I have tons of important data in that partition. Can I some how use the live cd to fix this problem??? I mean like re-install without losing data. Any help is greatly appreciated!!!

• How can I improve these online java programming puzzles I wrote for my (middle/high school) students?

  - by Arcymag

  I'm teaching some middle and high school students programming right now, and I found that some of them really liked online programming puzzles. So I created http://www.kapparate.com/coder/ , and right now there's 4 categories of puzzles. All the puzzles are set up right now so that variables are pre-initialized, and the user plugs in some code in the middle. For example, the problem might say these are pre-initialized: int x = ????; int y = ????; int z; and then the program might ask the student to write the final line of code: z = x + y;. Now I know I could go a long way in improving the usability of this site (like having an area that lists the pre-defined variables), but I was wondering if this concept seems sound. I know some sites have kids fill in functions, but not all of my students know what functions are yet, and I'm trying to introduce online programming puzzles before that.

• Deals Well With Ambiguity

  A while ago I was talking with my manager at the time about traits that we value in a Program Manager. He related an anecdote about an interview he gave where it became clear that the candidate did not deal well with ambiguity. This is an important trait for nearly every job, but especially for PMs as projects can often change on a dime and its important understand how to make progress amidst ambiguity and eventually drive towards resolving ambiguity. Lately, Ive been asking myself the question,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Opening programs very slow on ubuntu 12.10

  - by Mislav Blaževic

  When I open any program for first time after boot, it loads VERY slowly (Doesn't matter how long after boot). For example, terminal takes 2-3 seconds, skype and firefox often take much longer. If I close it and open again, it loads in reasonable time (<1 second). I got Intel Core i5-2500K CPU @ 3.30GHz, so it shouldn't be hardware issue... What is causing this? Disk benchmark: Average read time: 115.5 MB/s (100 samples) Average write time: 98.7 MB/s (100 samples) Average access time: 11.79 msec (1000 samples)

• Can I randomly generate an endless road?

  - by y26jin

  So suppose we stand on a position(x0, y0) of a map. We can only move on the horizontal plane(no jump and stuff) but we can move forward, left, or right (in a discrete math way, i.e. integer movement). As soon as we move to the next position(x1, y1), everything around us is generated randomly by a program. We could be surrounded by one of mountain, lake, and road. We can only move on the road. The road is always 2D as the map itself. My question is, are we able to play this game endlessly? "End" means that we come across a dead end and the only way out is to go backward.

Connection To SQL Server via Wifi Access Point to call the procedure afterwards. I am not developing a Barcode scanner, I am developing a UI Software like a Mobile App. I tried to google but I dont know what exact keywords I should search for.

• Dropbox and IIS

  - by DigitalAce7

  I'm running into the problem of using Dropbox and IIS. I am using the Dropbox Folder Sync plugin to sync a folder outside the Dropbox folder. They are synced into my inetpub\root\downloads\ directory. The problem is not that it doesn't sync. The problem is that the files that get synced have no permissions attached to them. I can't open any of them on IIS. Initially the downloads were to be only PDFs but they don't open so I tried an .ASPX file and it fails to load as well. Is there any way around this or another program I can use to sync files but allow them to be opened on an IIS server. Thanks for any help!

• design for interruptable operations

  - by tpaksu

  I couldn't find a better topic but here it is; 1) When user clicks a button, code starts t work, 2) When another button is clicked, it would stop doing whatever it does and start to run the second button's code, 3) Or with not user interaction, an electrical power down detected from a connected device, so our software would cancel the current event and start doing the power down procedure. How is this design mostly applied to code? I mean "stop what you are doing" part? If you would say events, event handlers etc. how do you bind a condition to the event? and how do you tell the program without using laddered if's to end it's process? method1(); if (powerdown) return; method2(); if (powerdown) return; etc.

• Last fortnight...

  - by rajeshr

  In the last fortnight, I had an opportunity to meet up with some very energetic folks, who actively participated in a couple of OU programs on Solaris 11 and MySQL. I thank them for their participation and hope all of 'em had a good learning experience showing up for Oracle University programs. As always, I'm publishing below a moment from each of the aforesaid programs. MySQL DBA session in Bangalore. It's unfair if I don't express my heartfelt thanks to each of 'em for a serious teach back session through out the training program and I wish to do so by publishing moments from each one's teach back assignment: Below is a class photograph from Solaris 11 Administration Session in Bangalore.

• Metro-style / iPhone apps development too demanding for newbie developers? [closed]

  - by linquize

  Both Metro-style and iPhone app require approval and publishing to app store. And they focus most on user interface and the quality of the software. Developers must deal with technical aspects, such as async programming (no UI blocking), no console program (must design a UI that cope with "Standard"), no CPU hungry (pause app if deactivated), need to study the permission matrix (not full access right), and more ... A newbie is not familiar with threading and synchronization. Do you thick they are too demanding for newbie developers? Can you give more examples how demanding it is?

• Making a sldprt to PDB file converter?

  - by user122083

  I wanted to create a parser that can read a solidworks file and turn it into a protein data bank file. This has already been done in a program called DiamondCAD. http://www.zyvex.com/Research/DiamondCAD.html I waant to make a parser that can parse the data and then visualize it the same way as DiamondCAD. I have downloaded and opened solidworks files before and they make no sense to me with never before seen symbols and looks like ancient writing. Does anyone know how a sldprt. file is structured and how it can be parsed into a PDB file? (A software called VMD converts a PDB to Obj. file so it is proof of concept)

• Programming Carreer. What should i choose? [closed]

  - by thenewbie

  I have an experience in programming. Im not that experience but i have created some desktop application like payroll etc. In web i had created some websites. Now im studying java for android. I already created an application on android and submitted it on google play.However, i feel like the excitement in creating application for android or web is gone. What i think i like is to program in c++ language. but i have a doubt mastering it. Because nowadays only a handful of company hire a c++ junior programmer. I think only in gaming industry that they would hire a c++ programmer and has an 3 or more years of xp. While in java there are lots of oppurtuniy especialy for android. and I dont have a plan studying objective c cause i dont have mac. SO what should i realy choose? thank you..

• Why have column borders gone missing in Rhythmbox gui?

  - by amadis

  My theme doesn't use shading, only borders/outlines. Since a few weeks ago Rhythmbox has stopped drawing all borders so that I can't see columns or sections very well. Even my scrollbars are not being drawn correctly. This makes the gui really hard to use. When I change themes it seems that Rhythmbox has changed its gui to use only shading to delineate sections, tabs, columns, etc.. Rhythmbox seems to be the only program that has this problem so I'm guessing this is a Rhythmbox thing, but not sure. My theme is not updated for gtk 3.6 Maybe that is the issue? Anyone know what's going on?
