  • Working with logout dialog box - text error

    - by aaron.kyle
    I am having a problem with the shutdown dialog box for Ubuntu 12.04. If I am logged in as any user and press shutdown, I see the box with the question 'Are you sure..." and its usual options. Shutting down when I am not logged in as a specific user, however, displayed only square boxes. An image of this error can be found here: I believe this error started a few weeks ago when i accidentally changed the group for my root system directory, so it might be a permission thing or an improperly assigned group lingering somewhere. The trouble is that I don't know where the text for this box is stored, and no idea where to begin checking. Can any one point me in the right direction?

  • Checking if an object has been released before sending a message to it

    - by Tom Irving
    I've only recently noticed a crash in one of my apps when an object tried to message its delegate and the delegate had already been released. At the moment, just before calling any delegate methods, I run this check: if (delegate && [delegate respondsToSelector:...]){ [delegate ...]; } But obviously this doesn't account for if the delegate isn't nil, but has been deallocated. Besides setting the object's delegate to nil in the delegate's dealloc method, is there a way to check if the delegate has already been released just incase I no longer have a reference to the object.

  • Ubuntu hang, and cannot be soft-reset after resuming from stand by mode

    - by Phuong Nguyen
    I have downgrade my xorg drivers, so I can hibernate and stand by my ubuntu smoothly. However, in some case, there's a problem. My ubuntu get hang. When I tried to switch to console mode (Ctrl+Alt+F1), then I cannot login. The system always reply with an error whenever I tried to press a key. When I press Ctrl+Alt+Del to perform a softreset, here what's it said: [80141.320122] end_request: I/O error, dev sda, sector 193687181 init: control-alt-delete main process (5660) terminated with status 2. This error is not even recorded in syslog. I guess this should be a problem with my hard disk since it said something about a bad sector. Exactly, what kind of error is this?

  • JavaScript - checking for any lowercase letters in a string

    - by pcampbell
    Consider a JavaScript method that needs to check whether a given string is in all uppercase letters. The input strings are people's names. The current algorithm is to check for any lowercase letters. var check1 = "Jack Spratt"; var check2 = "BARBARA FOO-BAR"; var check3 = "JASON D'WIDGET"; var isUpper1 = HasLowercaseCharacters(check1); var isUpper2 = HasLowercaseCharacters(check2); var isUpper3 = HasLowercaseCharacters(check3); function HasLowercaseCharacters(string input) { //pattern for finding whether any lowercase alpha characters exist var allLowercase; return allLowercase.test(input); } Is a regex the best way to go here? What pattern would you use to determine whether a string has any lower case alpha characters?

  • Password checking in dojo

    - by Richard
    I want to check that two passwords are the same using Dojo. Here is the HTML I have: <form id="form" action="." dojoType="dijit.form.Form" / <pPassword: <input type="password" name="password1" id="password1" dojoType="dijit.form.ValidationTextBox" required="true" invalidMessage="Please type a password" /</p <pConfirm: <input type="password" name="password2" id="password2" dojoType="dijit.form.ValidationTextBox" required="true" invalidMessage="This password doesn't match your first password" /</p <div dojoType="dijit.form.Button" onClick="onSave"Save</div </form Here is the JavaScript I have so far: var onSave = function() { if(dijit.byId('form').validate()) { alert('Good form'); } else { alert('Bad form'); } } Thanks for your help. I could do this in pure JavaScript, but I'm trying to find the Dojo way of doing it.

  • ROOT_MISMATCH error after following FAQ directions

    - by Adko
    While using Ubuntu One in 11.04 I am unable to change my account info. When I made the switch to 11.04 I forgot that I already had an Ubuntu One account so, I made a new one. However, upon going through one of my email accounts I found my old Ubuntu One login information. I then attempted to switch the account associated with my desktop to my first email. Now, despite following the directions found at https://wiki.ubuntu.com/UbuntuOne/FAQ/WhatToDoWhenSyncdaemonSaysRootMismatch I continue to get the error "File sync error. (local and server roots are different (ROOT_MISMATCH))". Any help would be appreciated.

  • Alternative to | more to display error results page by page

    - by Lane
    The command psql -d template_postgis2 -f /usr/share/postgresql/9.1/contrib/postgis-2.1/postgis.sql returns a list of errors that is too long to be displayed by scrolling up to the beginning of the error. I tried the same command with "| more" and "| less" added up at the end of the command but it does not display the message page by page as it should. I also tried to put the output in a file with "> file.txt" but I do not get in this new file what is displayed on the screen!! I don't understand why. I guess i can't do this with a psql command?? Is there any other way to get all the error message? Thanks for your help!

  • Checking type sizes in C with macros.

    - by Seisatsu
    I'm writing a program that needs to have unsigned types with definite sizes. I need a uint8, uint16, uint32, and uint64, and I need them defined in types.h, in a way that they will always be defined correctly regardless of platform. My question is, how can I check the sizes of different types on each platform using preprocessor macros, so that I can define my custom types correctly in the types.h header?

  • Checking if an SSH tunnel is up and running

    - by Jarmund
    I have a perl script which, when destilled a bit, looks like this: my $randport = int(10000 + rand(1000)); # Random port as other scripts like this run at the same time my $localip = '192.168.100.' . ($port - 4000); # Don't ask... backwards compatibility system("ssh -NL $randport:$localip:23 root\@$ip -o ConnectTimeout=60 -i somekey &"); # create the tunnel in the background sleep 10; # Give the tunnel some time to come up # Create the telnet object my $telnet = new Net::Telnet( Timeout => 10, Host => 'localhost', Port => $randport, Telnetmode => 0, Errmode => \&fail, ); # SNIPPED... a bunch of parsing data from $telnet The thing is that the target $ip is on a link with very unpredictable bandwidth, so the tunnel might come up right away, it might take a while, it might not come up at all. So a sleep is necessary to give the tunnel some time to get up and running. So the question is: How can i test if the tunnel is up and running? 10 seconds is a really undesirable delay if the tunnel comes up straight away. Ideally, i would like to check if it's up and continue with creating the telnet object once it is, to a maximum of, say, 30 seconds.

    - by ZaZu
    Hi there, Can someone please explain what really goes on in this code ? If I put the AND statement, the message wont show if values are less than 0 or greater than 10 ...

  • Error installing gPodder

    - by Ron Webb
    A few weeks ago (newbie alert!) I started using XUbuntu 12.04 with Xfce 4.8. I'm trying to install gPodder Podcast Client (see https://launchpad.net/~thp/+archive/gpodder). I've added the PPA via terminal commands as instructed. When I click the Install button in the Ubuntu Software Centre I get the following error: Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. Details: The following packages have unmet dependencies: gpodder: Depends: python-webkit but it is not going to be installed What do I need to do? Just to make thing more complicated -- I'm not sure, but before I found the launchpad.net link, I think I may have tried to install gPodder from the default Ubuntu repositories (also unsuccessfully). There may be remnants of the previous attempt still installed, which may be blocking the new install. Where/how can I find them?

  • Zotero error in libreoffice

    - by arno
    I installed Zotero standalone in 12.10 64bit. Some problems which I managed to fix. The one that remains is an error saying "openoffice.org could not communicate with Zotero. make sure zotero standalone or Firefox are open and set to an online state and try again". That's when I click any button in the Zotero toolbar in libreoffice. Firefox doesn't open with a the plugin installed and a working internet connection. The Zotero troubleshooting which mentions this error was of no help to me. I find reports about this bug going back as far as 2009 but I haven't found anything of help.

  • Automated URL checking from a MySQL table

    - by Rob
    Okay, I have a list of URLs in a MySQL table. I want the script to automatically check each link in the table for 404, and afterward I want it to store whether the URL was 404'd or not, as well as store a time for last checked. Is this even possible to do automatically, even if no one runs the script? ie, no one visits the page for a few days, but even with no one visiting the page, it automatically ran the test. If its possible, how could I go about making a button to do this?

  • Alternatives to checking against the system time

    - by vikp
    Hi, I have an application which license should expire after some period of time. I can check the time in the applicatino against the system time, but system time can be changed by the administrator, therefore it's not a good idea to check against the system time in my opinion. What alternatives do I have? Thank you

  • Checking digital signature on EXE

    - by LTR
    My .NET exe is signed using signtool. Using this code, I can verify the validity of the certificate itself: var cert = X509Certificate.CreateFromSignedFile("application.exe"); var cert2 = new X509Certificate2(cert.Handle); bool valid = cert2.Verify(); However, this only checks the certificate itself, and not the signature of the EXE. Therefore, if the EXE is tampered with, this method doesn't detect it. How can I check the signature?

  • How to fix additional STA driver installation error on 12.04

    - by nibl
    I have a Broadcom BCM4313 wireless driver. It worked fine under 11.04 and the upgrade to 11.10 also went smoothly. The 12.04 upgrade has broken the wireless connection. I've seen several posts about this and all presume you can activate the STA drivers, but that's where it fails on this machine. The log is in /var/log/jockey.log: WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: blacklisted, b43legacy: blacklisted (repeat of last error several times) Any ideas how to proceed?

  • GRUB install error

    - by Rohit
    Whenever I try to install Ubuntu, I get a fatal error that reads: 'Executing'grub-install /dev/sda' failed. This is a fatal error.' Its the same as this, but my graphics appear to be running fine. Also, I'm a complete novice at this and really need simple instructions to understand what I'm doing. I've tried booting from a LiveCD and a USB stick. I don't want to dual boot it because its an old computer that I erased XP and plan on only using Linux on it. When I used a USB stick and set the persistent file storage high, I was able to run it, but only as long as the flash drive was plugged in.
