• When do one give up on programming challenges to look at the solutions?

  - by snowpolar

  Recently, I have been trying to learn programming and improve my ability in writing method level code through practices on websites such as Codingbat.com However in the recent weeks I have been stuck for weeks at the last 2-3 questions of String-2/Array-2 and early String/Array-3 problems. It feels really tempting for me to give up and google online for the solutions, but I'm afraid that by doing so I may end up not improving my ability at all. I wonder if this is common and when faced with such situations how long do 1 wait before giving up to look at the solutions or to continue spending more weeks on trying to solve the problems by yourself? How do 1 really engage in effective deliberate practice to improve programming ability and attain the necessary problem solving techniques? Any formal techniques available to tackle the never seen before problems?

• purple screen when booting on lenovo G505s

  - by user1114795

  I successfully installed Ubuntu 14.04. I'm having the purple screen issue however even after making the nomodeset changes. It remains stuck on a purple screen. I can navigate through the menu options i.e Ubuntu, Advanced Options for Ubuntu, Memory Test, Windows Recovery Environment and Windows 8. I can't even boot into Windows 8. I'm totally new to this. If someone could please provide step by step instructions, that would be most appreciated.

• MySQLwith mutiple threads and processes

  - by Abhan

  I'm developing a telecom messaging platform in C, and I'm going to need multiple processes to be working with MySQL DB. How can I make two processes read/write to/from a Mysql DB and, if/when one of them goes down, get the other to seamlessly take over the work until the dead process gets back to work? I was thinking/googling some options and am stuck in place where I don't know which one to choose. What I think so far is that table lock is not the best option to go for, as it will stall the other process until the table is unlocked. The other option is to use row-level locks or manual locks, but I can't find the best way to do it.

• Why don't more companies hire remotely?

  - by James

  I keep hearing about the desperate recruiting efforts of companies in tech hubs such as SF and NYC. However, every time I'm contacted by a startup I'm told the position is on-site and working remotely isn't possible. Let me clarify that these are tech startups. They should be very comfortable with the idea of using technology to get things done and connect teams together. With the housing market the way it is, many of us can't relocate even if we wanted to pay the higher cost of living. Why are so many companies still stuck in the industrial mindset of butts in seats?

• Unable to boot 12.04 server: no LVM activated and impossible to mount /

  - by baronKarza

  I'm stuck in the Busy Box shell after upgrading from Ubuntu server 11.10 to Ubuntu server 12.04 64 bit. During the booting phase the system hangs while mounting root filesystem. My system is so configured: /dev/sda1 -- /boot /dev/mapper/vg-lv_root /dev/mapper/vg-lv_var /dev/mapper/vg-lv_tmp When the boot process fails and I'm forwarded to the busybox shell, if I type vgchange -ay I can mount my volumes and all it's OK. But it does not enable LVM automatically so that it is impossible to mount root, var, and tmp. I tried to start with a Knoppix, chroot, reinstall (aptitude) both kernel and lvm2 as suggested by this tread "Fixing unbootable installation on LVM root from Desktop LiveCD": nothing changed. I can't figure out what is the problem. Any suggestion is welcome. Thanks in advance.

• Copy 2 databases without detach in SQL 2005

  - by molgan

  Hello I have a server with live databases, and I have a test-server where I sometimes restore databases from the live one, to get fresh data. But this way I have to set up all the users again, I have about 4 different users with different permissions that need set again. Is there some way to do this a better way without using detach and attach, since I cant take the databases offline on the live-server? Prefered some thing I could run that "re-fills" the tables with fresh data. No need to redo stored procedures and rights. /M

• How to reinstall latest Ubuntu Touch on Nexus 4?

  - by Galen Gruman

  I've followed the instructions on https://wiki.ubuntu.com/Touch/Install, first doing the steps that lead to phablet-flash -b and then the manual ones. In both cases, I get stuck at the Google boot screen. It does not boot into Touch. No errors during manual install, and adb devices shows the device, but I get the following with phablet-flash or phablet-flash -b (second and subsequent times, not the first time): Device detected as /system/bin/sh: getprop: not found Unsupported device, autodetect fails device When working on flipped images, detection does not work and would require -d Not clear what that all means. The Nexus 4 had the initial Touch dev preview on it, FYI. I saw no separate instructions for upgrading from that.

• How do Ruby and Python implement their interactive consoles?

  - by sxa

  When implementing the interpreter for my programming language I first thought of a simple console window which allows the user to enter some code which is then executed as a standalone program as a shell. But there are severe problems: If every line of code the user enters is handled as a standalone program, it has to go through the tokenizer and parser and is then just executed by the interpreter - what about functions then? How can the Python/Ruby interactive consoles (IDLE, irb) "share" the code? How is the code entered handled? Example: >> def x: >> print("Blah") >> >> x() Where is the function stored so it can be called at any time again? How can the interactive console take everything entered as obviously one program without executing everything over and over again?

• Flex Builder 3 executing old source codes

  - by Gorro

  I'm facing this problem again and again, but can't find any solution (except mine, which is not as a good one I guess). Don't know why, sometimes Flex Builder executes old source codes after making changes. While debugging I see how it steps through a source (e.g. changing local variables) which does not exist (even if I delete all that block or function). My way to solve that is to delete the project (backing up the source codes of course) and create a new one, add the backed up sources to the project and rebuild. It starts to work as it should work, but this way is not as comfortable, especially if sources are on a remote machine and you need to configure .net back-end. Anyone knows how to solve?

• Looking for bug tracking software

  - by Shelton

  I'm looking for a bug/issue tracking system that can: Integrate with lots of other services. Basecamp, Beanstalk, etc. Integrate popular CMSs, such as WordPress, so the client can enter a ticket from the system that is familiar to them and not have one more login to worry about. Generate reports for my own purposes. Bonus if there's an iPhone app. Doesn't require additional development on my end (I have plenty of money and no time). I've already looked into Lighthouse and ZenDesk -- both are solid offerings -- but don't see what I need out of the box. I'd have to build CMS plug-ins. And I've looked through WP plug-ins for bug tracking software, but nothing I've found integrates with these products. Anyone know of something that meets these requirements without additional development, or am I stuck putting my business on hold to get this piece in place myself?

• Need help with AMD catalyst control center

  - by user254074

  I just built my first HTPC and I hooked it up to my Sony KDS-R60XBR1 and I am having display issues. I believe this is only a 1080i display and when I select 1920x1080 on the resolution I get strange lines on the display when anything moves on screen. I am guessing this is because it is putting it in 1080p and the TV cannot process that. As of now I have lowered the resolution and that worked but I would like to get this set at 1080. Also I cannot change the underscan. I am stuck with black borders around the display image. When I pull up the catalyst control center on my computer I am able to adjust all of this stuff but on the one on my HTPC with the TV display I have no options. See images below.

• Stop native web app from reloading itself upon opening on iOS

  - by cguedel

  I'm trying to build a "native web app" using HTML + JS on iOS. As you may know you can add such an application to the homescreen and it will more or less look just like a normal native app. However if I quit such an app and reopen it again it reloads the whole page again. This also happens when switching to such an application from another over the multitasking bar. Is this expected behaviour or is there a way to stop the device from doing this? As an example you can add the jqTouch-Demos from here to your homescreen and test it: http://jqtouch.com/preview/demos/main/

• How to remove an observer for NSNotification in a UIView?

  - by sudo rm -rf

  Hello! I've added an observer in a custom UIView I've created under initWithFrame:. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateZipFromLocation:) name:@"zipFoundFromLocation" object:nil]; The problem is, this view is a subview. When the view is loaded again, it calls the initWithFrame message again, thus adding two observers and so on. How can I remove the observer when the view is going to disappear? Since it is a UIView, it says that viewWillDisappear:(BOOL)animated is not a valid method. Any ideas?

• WinTV-HVR-1900 no picture in VLC

  - by nLinked

  I've connected a Hauppauge WinTV-HVR-1900 to my Ubuntu 10.10 PC and used the instructions here to install the firmware and test that it is detected using dmesg. Detection is successful. The WinTV is connected to my TV using component connections. I run this command to enable the component interface: v4l2-ctl -i 1. Then I use cat /dev/video0 test.mpg, and that file is created and plays perfectly with video and sound. However, when I try to play /dev/video0 in VLC Player (and other players), I just get a black screen. I also try the v4l2-ctl -i 1 command before I try it in VLC, but I still get a black screen, and when I use v4l2-ctl -I, it shows it has connection 0 again (Television), so it reverts back to connection 0 instead of connection 1 (component). So I'm a little stuck with getting VLC to get a picture, even though the CAT command works fine. Anything I can try?

• How do I set a wine program (ex. Foxit Reader for Windows) as the default program?

  - by To Do

  I regularly annotate pdf files and unfortunately there is no good linux pdf reader that supports decent annotations. Evince has a very rudimentary and buggy annotation feature. So I'm stuck using a Windows viewer through wine. This works pretty well but, when I simply right-click a file (in this case a pdf), properties, open with and selected Foxit Reader, the Unity Launcher icon remained the wine icon instead of the application icon. Has anyone set a wine program as the default program for any file? Any ideas?

• Open an Application .exe window inside another application

  - by jpnavarini

  I have an application in WPF running. I would like that, when a button is clicked inside this application, another application opens, with its window maximized. However, I don't want my first application to stop and wait. I want both to be open and running independently. When the button is clicked again, in case the application is minimized, the application is maximized. In case it is not, it is open again. How is it possible using C#? I have tried the following: Process process = Process.GetProcesses().FirstOrDefault(f => f.ProcessName.Contains("Analysis")); ShowWindow((process ?? Process.Start("..\\..\\..\\MS Analysis\\bin\\Debug\\Chemtech.RT.MS.Analysis.exe")).MainWindowHandle.ToInt32(), SW_MAXIMIZE); But the window does not open, even though the process does start.

• Bomb timer adventure game win32 c++ [on hold]

  - by user3491746

  I'm working on an adventure game in win32 and opengl for my 2nd year university project for class. I am pretty much finished my game but I'm stuck on the concept of how to program a timer which outputs hh : mm : ss -- but which countdown, not up. I've made a clock which counts up using vector matrices and the segxseg matrix algorithm but I cannot figure out how to make a clock (it can be simple even text using wsprintf) that counts down in that format. Can anyone possible give me an example or some literature that I can read on how to do this? Please dont suggest for me to use another environment, I've already been working here for 2 months on this game, and I'm pretty much done so i'm at no point to switch over. Can anyone show me how I can take a shot at this component of my project? Thanks a bunch! Anything that I can get is appreciated.
