• Why does this PowerShell script hang?

  - by jshin47

  Today I had to use Start-Sleep many times so I thought I would create a shortcut function for it, sleep($time). However, whenever I entered the function it never exits! It must be an issue with either the data type for the argument for Start-Sleep or the way I am declaring the function. Instead of posting the whole script, I've posted this useless one that would make a familiar beep pattern if it worked: function beep { Write-Host `a } function sleep { param([int]$time) Start-Sleep -m $time } beep sleep(300) beep sleep(200) beep sleep(50) beep sleep(300) beep sleep(450) beep sleep(200) beep

• Why does yum index get corrupted?

  - by TomOnTime

  Occasionally yum's cache gets corrupted and we see errors like this: error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery error: cannot open Packages index using db3 - (-30974) error: cannot open Packages database in /var/lib/rpm The workaround is rm -f /var/lib/rpm/__db* and then the next "yum" command regenerates the data. My question is: what is likely to be causing this? Is there some common task that ignores locks or has other problem that causes this? We have hundreds of CentOS machines and there is no pattern to which see this problem. It could be a "one in a million" issue, which at large scale is seen often. NOTE: I realize this is a very "open ended" question, but if an answer finds the cause, I will go back and turn the question into something more canonical that directly relates to the specific issue.

• Misbehavior in regular expression in VIM

  - by poissonbreaker

  I am having a problem with a regular expression on vim. I have a pattern as follows: http:\/\/\(\w\+\.\?\)\+ [matches http://(AS MANY WORDS FOLLOWED BY DOT OR NOT ENCOUNTERS) e.g. http://wd1.wd2.com] I have a text as follows: http://wd1.wd2.com/wd3 I am trying to make this substitution on it: s/\(http:\/\/\)\(\w\+\.\?\)\+/\1wd4.wd5.com and the result is http://wd4.wd5.com /wd3 (Notice the white space inserted at the end of the replacement) How can I avoid having this inserted space? I am afraid is a bug in the regexp engine but I am not sure.

• How to get rid of disturbance on LCD monitor?

  - by Uday Kanth

  I have an Acer G195HQL LCD monitor and recently I've been noticing a lot of disturbance on the screen. They appear to be like flickering horizontal white lines. These lines are more apparent on dark backgrounds like grey/black. The curious thing is that, the intensity of these lines increases and decreases with no specific pattern. The disturbance temporarily goes away when I detach and re-attach the VGA cable at the CPU end. My speakers are magnetically shielded, but the problem persists even when I turn them off. I don't know what to do and this is really annoying me. Is it possible that my monitor is failing? Or is there anything I should check?

• Caliburn.micro View ViewModel name resolution issue

  - by user1459773

  I am using a namespace called ComShorCaliburnWPF.ViewModules.Views.ShortMenuWindows.GWDSCT on my View.xaml and View.cs, for my ViewModel.cs and my IoC container I am using ComShorCaliburnWPF.ViewModules.Views.ShortMenuWindows.GWDSCT. When I remove the GWDSCT at the end it works fine, but in its current state it does not. I would like it to work how it is now because it accurately reflects where the files are located. Any suggestions?

• Why is Matlab Stateflow 7.7 not throwing errors on undefined variables?

  - by Pyrolistical

  Previously in Matlab Stateflow 7.1 all variables and functions had to be included before they can be referred to in the state diagram or else it would throw an error when you tried to parse the diagram. But now in 7.7 it doesn't catch those kinds of errors. Its still compiling the diagram because it catches other syntactic errors. Am I missing an option somewhere? Can this be turned on?

• iPhone Application failing to come back from sigkill

  - by overscore

  I have no idea if this is intended behaviour, but whenever the application exits (say, the user is double-clicking the home button and pressing on the red dash on the icon) I get the dreaded SIGKILL. Now, when I try to launch the app again all I get is the old screen state and a frozen (I presume ?) program. It could be because of clunky memory management, but NSZombieEnabled doesn't seem to agree. Any thoughts ?

• Multi-machine backup solutions

  - by Paul

  I have a growing number of PCs and laptops in my home that need a backup solution. My question is 2 fold: Most commercial backup vendors appear to license by the machine, are there any products that give a license that can be used on all your machines, without a per machine cost? An alternative is to have a centrally controlled back up strategy controlled from a single PC with an attached hard drive that can back up other machines on the network. What backup software is suitable for this approach? Will this software be windows/Linux interoperable? I've searched for duplicate questions but don't see anything that addresses the multi machine/cost issue. OSs in network will be Windows (XP, Vista, 7) and Linux variants. Not pattern to when machines will be switched on.

• My Android game runs out of memory when it is closed and opened and couple times.

  - by sirconnorstack

  I have an Android game that has an activity for the menu, and then another activity for the game that creates a SurfaceView and Thread to deal with canvas drawing and game logic. When you exit the game and start it up again too much or if you open and close the keyboard (thus restarting the activity), the game runs out of memory, usually when loading a bitmap: java.lang.OutOfMemoryError: bitmap size exceeds VM budget How can I keep all my images in memory without loading them again when the game changes state, or how can I release them from memory and let them reload when the game is restarted?
