  • How to disable the alt-hotkey behavior on gnome terminal?

    - by farleyknight
    This is not just gnome terminal, but pretty much all gnome windows: When you hold the "alt" key, you can press the first letter of one of the menu items. This will let you scroll that menu without clicking on it directly. This is okay on any other window, like say Firefox, but on gnome terminal, it steals the keys I use for emacs!! There is very little chance of me learning a new set key combinations if I can avoid. If I can't isolate this just to gnome terminal, I'm fine with that.

  • Patterns to refactor common code in multi-platform software

    - by L. De Leo
    I have a Django application and a PyQt application that share a lot of code. A big chunk of the PyQt application are copied verbatim from the Django application's views. As this is a game, I have already an engine.py module that I'm sharing among the two applications, but I was wondering how to restructure the middle layer (what in Django corresponds to the largest part of the views minus the return HttpResponse part) into its own component. In the web application the components are those of a classic Django application (with the only exception that I don't make any use of models): the game engine the url dispatcher the template the views My PyQt application is divided into: the game engine the UI definition where I declare the UI components and react to the events (basically this takes the place of the template and the url dispatcher in the Django app) the controller where I instantiate the window object and reproduce the methods that map the views in the Django app

  • Windows errors, how do I find root cause and fix it? Getting several errors

    - by Eric Martin
    My server is having issues and not responding to customer's https requests. I checked the event viewer and found several errors. These two are listed a couple of times: WINS encountered a database error. This may or may not be a serious error. WINS will try to recover from it. You can check the database error events under 'Application Log' category of the Event Viewer for the Exchange Component, ESENT, source to find out more details about database errors. If you continue to see a large number of these errors consistently over time (a span of few hours), you may want to restore the WINS database from a backup. The error number is in the second DWORD of the data section. And this one: An error occured while using SSL configuration for socket address 0.0.0.0:444. The error status code is contained within the returned data. SQL Server is not ready to accept new client connections. Wait a few minutes before trying again. If you have access to the error log, look for the informational message that indicates that SQL Server is ready before trying to connect again. [CLIENT: xxx.xxx.xxxx.xxx] I also found this in the event viewer but the computer has been restarted since this message and I have not seen it again. Configuring the Page file for crash dump failed. Make sure there is a page file on the boot partition and that is large enough to contain all physical memory. This is my virtual memory settings: I'm not familiar with WINS so I wasn't sure if that is where I start or how to resolve it. Is the WINS error causing the other problems or should I be looking somewhere else?

  • I accidentally hijacked my localhost

    - by Zach L
    Opening localhost in the browser is pointing a local webpage (examplePage) after playing with some config files a while back, and I can't figure out how to restore the default behavior. Background: I have XAMPP installed on my Windows 7 machine, and a webpage at c:/xampp/htdocs/examplePage. A couple weeks ago, I was on a mission to get sites root-relative urls (/resource) to work, so I played around with a bunch of apache/conf files, including httpd.conf and httpd-vhosts.conf and also was messing with the Windows hosts file. I gave up at some point, didn't document exactly what I did, and have since probably forgotten some of what I did. Many of my changes stemmed from suggestions in this StackOverflow post What I've Tried I commented out my additions to the hosts file I turned off XAMPP (thus hopefully negating any apache config file effect) I reverted to my original DocumentRoot in httpd.conf anyway (xampp/htdocs) localhost still displays examplePage. Even with xampp turned on (my reverted DocmentRootisn't taking effect) Does anyone know what I may have done and how I can fix it? Update : Its been resolved, thank everyone so much in taskmanager, theres a couple instances of httpd.exe (Apache HTTP Server). I ended these, and opened XAMPP, restarting apache. all references to examplePage in my .conf files that I could find had been commented out or removed. I imagine that the old versions were still in effect for some reason, and manually ending the Apache processes fixed this. As a point of interest, Its still a mystery why those processes were running - I cannot reproduce that situation. I must've stumbled upon a XAMPP bug of some sort.

  • lubuntu issues with desktop directory

    - by Hongxu Chen
    My lubuntu 12.04 is upgraded from the 11.10 version and I'm a Chinese user. What surprises me is that the directory shown on the initial screen is always changing! recently It seems to be mapped with the directory called w in my home directory(~). However when using pcmanfm to open the directory it usually shows odd string as to the name of the folder that cannot be print, which I think may be some Chinese characters.The directory also sometimes fails to appear in the window appeared first when logged in. I know the lxde has no conception of the shown folder and I think the lubuntu team has done some optimization. Can someone tell me what's happening?Thanks in advance.

  • Dummy Guide to NetBeans Android Development

    - by Geertjan
    Start by setting up the Android SDK (fantastic Ubuntu instructions here), then install NBAndroid. Now you can create a new Android project: Having set up the Android SDK, you're able to select your Android platform in the IDE: The project structure created by the above templates is nice and easy to understand: Build the project and you have your APK file and everything else generated in the Files window: Nice features are included, such as code completion in Android XML files: Several other features are included, as described here, such as "Export Signed Android Package", as well as deployment to the Android emulator. Now that I have everything set up (took literally about 10 minutes from start to finish), I'm going to be experimenting a bit with Android development via NetBeans IDE.

  • Qt Certification Exams

    - by karlphillip
    I'm wondering about doing a Qt Certification Exam this year, but I'm not 100% sure the investment is worth. I'm considering it because I think it could be a nice + on my resume, and as you know, I'm all for improving my software engineer persona. As I already earn a BSc and MSc degrees in computer stuff, I guess I see the certification process as some kind of adventure. Anyway, I know I'll spend a lot of time preparing myself for the exam and I just wanted to know if a Qt certification is worth the effort. Apparently there are 2 certificates that you can get in the Qt world: Nokia Certified Qt Developer (basic) Nokia Certified Qt Specialist (advanced) Nowadays I build cross-platform software in C++ and this exam would fit beautifully in my resume. My main concern is that, given the obscure future of Qt, I might be throwing time and money out the window. I'm looking for some advice regarding the usefulness of such certifications.

  • Bzr Eclipse Plugin not configurable

    - by Ubuntourist
    I'm relatively new to Eclipse. I'm currently running bzr 2.2.1 and Eclipse 3.5.2 (Galileo). Following the directions at: http://wiki.bazaar.canonical.com/BzrEclipse/Installation I get to the point where it tells me the plugin has been successfully installed, but when I attempt to configure it at Window -- Preferences -- Team -- Bazaar, there's no "Bazaar" there. Team shows CVS, File Contents, Ignored Resources and Models. (Nothing useful under CVS.) Nothing in ~/workspace/.metadata/.log about bzr either. I've uninstalled and reinstalled the plugin a few times, to no avail. Is there a more thorough way to uninstall that plugin without removing everything else that's been installed? Is there somewhere else I should be looking for the source of trouble? I didn't see anything promising on Launchpad, but may not have looked deep enough.

  • SQL Server Backup problem when browsing to the directory

    - by Richard West
    I want to allow a group (eg. 'BackupManagers') who can only preform backup and restore operations on certain databases. When creating the BackupManagers user account I checked db_backupoperator. When the user logs in to create a backup they get an error message similar to the following when the select Tasks - Backup - Click on Add in the destiantion block - click on the "..." button to browse TITLE: Locate Database Files - MYSERVER\SQL2005 E:\MSSQL\Backup Cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists. If you know that the service account can access a specific file, type in the full path for the file in the File Name control in the Locate dialog box. I have confirmed that the user has permissions to the folder. I have even created a share to this folder and had them access it through explorer. They are able to create and delete files within the folder. I have found that if they type in the path to the file instead of using the "..." button to browse the directory tree then they can create a backup file fine. Why is the browse button not working as expected? Thanks!

  • Windows 7 - Windwos XP - sharing - why isn't working?

    - by durumdara
    Hi! This is seems to be "hardware" and not "software" / "programming" question, but I need to use this share in my programs, so it is "close to programming". We had an XP based wireless network. The server is XP Professional, the clients are XP Home (Notebooks). This was working well with folder sharing (with user rights, not simple share). Then we replaced the one of the notebook with Win7/X64 notebook. First time this can reach the server, and the another client too. Later I went to another sites, and connect to another servers, another networks. And then, when I return to this network, I saw that I cannot connect to this server. Nothing of resources I see, and when try to dbl click on this computer, I got login window, where I can write anything, never I can login... The interesting part, that: Another XP home can see the server, can login as quest, or with other user. The server can see the XP home notebook. The Win7 can see the notebook's shared folders, and XP home can see the Win7 shared folders. The server can see the Win7 folders, BUT: the Win7 cannot see the server folders. Cannot see the resources too... The Win7 is in "work networking group", the group name is not mshome. I tried everything on the server, I tried to remove MS client, restore it with simple sharing, set guest password, etc., but I lost the possibilities to access this server from Win7. Does anyone have any idea what I need to see, what I need to set to access these resource - to use them in my programs? Thanks for every info, link: dd

  • Missing boot files in Windows 8

    - by Alex F. Sherman
    I had a partition with Windows 8 Release Preview, Windows' System Reserved partition and the empty space of the beginning of disk. I moved two partitions to the beginning of disk using Ubuntu Live CD and GParted. After that, the Windows Loader didn't boot and throw an error about missing files. I fixed it using the commands: bootsect /nt60 sys /force /mbr bootrec /rebuildbcd bootrec /fixboot bootrec /fixmbr When I used "Automatic repair" option from "Advanced boot" menu, it throw an error like: Windows can't fix your boot problems. For more information see file C:\Windows\System32\LogFiles\Srt\SrtTrail.txt In this file I found a description of the system repair actions and at the end of file: Boot status indicates that the OS booted successfully. Now, when I use the Advanced boot menu from Windows 8 (PC settings - General - Advanced startup) I receive an error: Restart your PC to try again. It looks like something didn't load correctly. Restarting might fix the problem. If this happens more than once, you might also be able to find help by searching online for the specific error code. Erorr code: 0x8007090. 0x80070490 is the error code ERROR_NOT_FOUND. What are the missing boot files and how can I restore them? List of files in System Reserved Partition: B:\bootmgr B:\BOOTNXT B:\Boot\BCD B:\Boot\BCD.LOG B:\Boot\BCD.LOG1 B:\Boot\BCD.LOG2 B:\Boot\BOOTSTAT.DAT B:\Boot\Fonts B:\Boot\memtest.exe B:\Boot\qps-ploc B:\Boot\Resources B:\Boot\Resources\bootres.dll and many *.mui and *.ttf files.

  • How can I remove gradients from Elementary theme?

    - by John
    I really don't like the gradients in the Elementary theme and I was wondering if there is a way to remove them from applications like Nautilus-Elementary, Postler, Dexter, etc. I've tried commenting out the Apps/[Application].rc in /usr/share/themes/elementary/gtk-2.0/gtkrc but it doesn't work. It still leaves the gradients in their place. I'm a big fan of the other controls in the theme: the scroll bar, the way it borders gedit and the buttons, and I'd like to keep these features, but I don't like the way it styles its windows. EDIT: The gradients I'm talking about are the ones at the top of the window. Some examples: Nautilus-Elementary: Postler: Rhythmbbox: Transmission: I'd like to create a sort of matte look, similar to this, which was done using Orta: Nautilus-Elementary: Postler: Rhythmbox: Transmission: I'd like a flat color, preferably without the line separating the top part of the application with the bottom.

  • 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!

  • Updating a backup image (.wim and/or Acronis .tib)

    - by Backdraft
    Anyways, I've got a Windows 7 installation that I want to make a generalized backup image of so I can use it for future installs on not only my desktop from which the image is to be derived from, but also other systems with dissimilar hardware. Therefore I've arrived at either 2 options, using either sysprep/imagx from WAIK (guide here), or the simpler Acronis True Image w/ their Universal Restore addon. Of course, they create distinct image file types, .wim and .tib respectively. What I'd like to do is to periodically update this image, say with Windows Updates, by booting it to either a physical partition or using virtualization (VirtualBox/VMWare), perform the updates, and save the updated .wim or .tib image file again. What's the simplest way I could do this? Another question is, I created this generalized backup image on a 500GB Seagate 7200RPM HDD. Say I get an SSD as an OS drive in the future, can I just deploy this backup image to the SSD normally, or are there any potential problems to be aware/avoid (ie. is it best to completely reinstall the OS on the SSD from scratch, or can I use the image created on the normal HDD with no issue)? Thanks and Happy Holidays.

  • Mustek 1200 CP driver SFC4.SYS bluescreens with BAD_POOL_HEADER

    - by Slink84
    I have Windows XP SP2. Recently it started bluescreening right after starting up with 'BAD_POOL_HEADER', 0x00000019 error caused by SFC4.SYS driver. After googling for a while I've found out that this is my Mustek's 1200 CP scanner driver. Booting in safe mode and uninstalling it solved the problem... And created another one: now I can't use my scanner. The weird thing is, that it has been working for a while on this PC without any problems. It all started suddenly, and I can't remember installing anything that might have affected it. Reverting to several earlier system restore points didn't help. I've tried re-installing it from the Mustek website, just in case if my copy got corrupted or infected by a virus, but it did not help - it still bluescreens. Also, I've installed Avast and scanned my PC - there were no viruses found. If anyone had such a problem before or has an idea what might have caused it, please help. ED: @Michael Todd: ...try installing on another PC... I've installed it on my friends PC. He has the same OS version, with the latest updates just like mine (he wasn't too happy, even after I've assured him that it is easy to fix by uninstalling that driver :] ). It worked fine - no bluescreens or whatsoever. So I think I've narrowed it down to either BIOS settings, or some wicked driver conflict. Next thing I'm going to try is to re-install XP, or install windows 7. I'm not too happy with a prospect of mucking about with BIOS settings...

  • Ubuntu 14.04 and Dell E6440 - sound and mouse working after suspend/resume

    - by slawek.mikula
    I've installed fresh Ubuntu 14.04 on Dell Lattitude E6440 and i've encountered two strange issues when doing full system start/restart: - mouse scroll when full restart is working very fast. One turn of the wheel cause very large change of value (window scroll, sound change etc.) But when i suspend and resume laptop it starts working correctly (one turn of the wheel and small change of value - the same as in previous versions of Ubuntu) - sound from speakers - the same issue. When full restart the sound does not come from internal laptop speakers. It works though through headphones. After suspend/resume internal speakers starts to work. What can be a cause of these issues ?

  • OpenVPN, install a TAP adapter

    - by GolezTrol
    When I try to connect to my work VPN using OpenVPN, the connection fails with the message: All TAP-Win32 adapters on this system are currently in use. Many sources suggest to look in Control Panel\Network and Internet\Network Connections an enable the TAP adapter, but when I look there, there is none. Now I've run addtap.bat which is provided with OpenVPN, but I still don't get to see any TAP adapter, and logging in in VPN still fails. The output of addtap.bat is C:\Windows\system32>"C:\Program Files (x86)\OpenVPN\bin\tapinstall.exe" install "C:\Program Files (x86)\OpenVPN\driver\OemWin2k.inf" tap0801 Device node created. Install is complete when drivers are updated... Updating drivers for tap0801 from C:\Program Files (x86)\OpenVPN\driver\OemWin2k .inf. Drivers updated successfully. I've Run As Administrator both the setup of OpenVPN and addtap.bat. I've run deltapall.bat to remove any (maybe hidden) adapters. It said it removed three of them, after which I ran addtap.bat again to try to create another one. I also run OpenVPN itself as administrator. What's wrong? Running Windows 7 Home Premium on a HP Pavilion dv7 4050ed. It has worked before, but I recently had to reinstall my laptop, for which I used the restore disks I created when I just got it. Everything else seems to work fine. == UPDATE == The TAP adapter is found in Device Manager, but apparently it is disabled because it is incompatible with Windows 7 64bit. I've deïnstalled OpenVPNGui, downloaded a version that should be 64bit compatible, and installed that. Still no cigar. Then I found a tip to install OpenVPN (version 9) after installing OpenVPNGui, because that installs OpenVPN version 8. Now I got a v9 TAP driver in Device Manager, but it still doesn't work and shows up in device manager with an exclamation mark, and not at all in my network devices.

  • Firefox 4 on 10.10

    - by Oxwivi
    I installed Firefox 4 from the daily builds PPA, and it doesn't seem to be the latest RC, and tells me that I'd better update to it. How come a daily build is behind snapshot releases like beta or RC? I used the profile for my Firefox 4 on Windows, and the Global Menu (or whatever it's called) has gone to the right side. I had a few app tabs saved in the profile. What gives? How do I get the Global Menu to be orange or whatever color it's supposed to be? How do I pin it to Unity? Update Global Menu back on left side after restoring toolbar to defaults. However it's noteworthy that I could not drag it to the other side while the customization window was open unlike the other elements.

  • Prevent nautilus showing partition mounted in bash script

    - by bcbc
    In my bash script I mount partitions, check them, copy files to them, and unmount. When the script mounts the partition, Nautilus pops up with a Window showing the partition and stealing focus. This is something I want to avoid. Note: I know I can change the behaviour of this in System settings, Details, Removable media, Never prompt or start programs on media insertion, but I don't want to change the behaviour e.g. if a USB stick is plugged in, I just want to prevent it in my bash script. Actually this auto display doesn't seem consistent. If I do the exact same command from the terminal, Nautilus doesn't show, and I know there are other mounts in my script that don't show. So what could be causing this? Here's an example of the code: mkdir -p $target/home mount $target/home $homedev Thanks in advance

  • Laptop not syncing with Ubuntu One

    - by Lolwhites
    I have a desktop running Maverick, and a laptop running Lucid. Both are supposed to be linked to my Ubuntu One account. The desktop syncs fine, but when I started the laptop for the first time in a couple of months, it wouldn't sync any more. The Ubuntu One Preferences window either reports "Synchronisation complete" even though no recent files have been downloaded nor have any test files created in the relevant synced folder been uploaded, or it says "Synchronisation in progress", which does not appear to be happening as it stays like this for ages and the lights on my router suggest no traffic is going through. Have repeatedly tried disconnecting and reconnecting, and removing the device from the account then reattaching it, all to no avail.

  • VMware and Windows Activation

    - by Peter M
    Yesterday I installed Slysoft's Virtual CloneDrive in order to mount an iso for some software installation on my host system (XP Pro SP3) This morning I fired up VMware and made a linked clone of an existing XP vm in order to do some software testing. This is the sort of thing that I do all the time, and the base XP vm that I clone was activated a long long time ago. The surprise today was that the newly cloned vm was no longer activated and XP cited major changes in hardware as the reason. I repeated the test with a full clone of the base system and got the same message. I then started up my base vm and it seemed to be activated, yet another vm (which I fully cloned from the base vm a long time ago) now started reporting that XP was not activated. At this point I guessed that Virtual DriveClone might have been the source of my hardware differences so I uninstalled it and rebooted. After this I made a new linked clone and full clone of the base vm and XP did not complain about not being activated. So I seem to be back to where I was before installing Virtual DriveClone with the exception that that one particular XP vm continues to complain about activation (even though 4 or 5 other XP vm's are fat and happy) Now to my questions: Why would adding Virtual CloneDrive to the host system affect XP activation on the vm's? From their point of view I would have thought that the environment had not changed as I had not enabled any new hard drives in their systems. Or is adding a hard drive to the host system enough to upset XP activation? Since this event, one of my fully cloned vm's is still reporting that XP is not activated even though I have removed Virtual CloneDrive. Is there anyway to convince XP that it is on the same system as yesterday? Or are my only options to do an activation or restore the vm from a previous backup?
