• How to clear unshown OSD notifications

  - by Avatar Parto

  I am a webmaster of 2 active websites. Every time I start Thunderbird, it downloads all the new messages from the admin mail addresses of these sites - [email protected], [email protected], [email protected], etc. There are about 20 of them - this includes my personal email accounts. Now, am not always connected to the internet and there arises cases where I need to access already downloaded mails. Thunderbird then tries to connect to the internet, which it can't coz am offline, and then displays about twenty OSD notifications, one after the other, telling me that connection for each email address has failed. That's frustrating and it really eating me up. Am looking for a way, either: 1. To tell Thunderbird NOT to connect to the internet when am offline, or 2. To clear all these notifications after like the first one shows. And if it will help, am using ubuntu 13.04 and Thunderbird 24.0 and I always keep my computer fully updated. Any help is welcome. Thanxs.

• Can't access Terminal anymore, only shows a cursor

  - by user138304

  I run OS X. Following these directions (Installing MySQL on Mac OS X) I added a file to /usr and the contents were PATH=/usr/local/mysql/bin:$PATH Actually I was trying to get the mysql command to work now I cannot access terminal. All I get is a cursor but no command line. I also cannot find the file I created in the Finder. I used command shift G to find the folder /usr and the file is not there. Edit: I Solved the problem by restarting my computer. I am really not sure what the problem was. I got the idea because Could not open a new pseudo-tty. appeared in my terminal after following slhck directions to remove my .profile file. I then searched google and found this; http://blogs.oreilly.com/digitalmedia/2008/03/fixing-terminal-tty-errors.html. Thanks

• Show Slave Status not working from console, nor client.

  - by Mr. Leinad

  Hello, I have a somewhat strange case. Whenever one of my coworkers executes this line: show slave status; from their MySQL clients, it works smoothly. But if I do that, it says: ERROR 1227 (42000): Access denied; you need the SUPER,REPLICATION CLIENT privilege for this operation We are all going against the same database, and if I check privileges I can see: GRANT ALL PRIVILEGES ON . TO 'usermysql'@'%' IDENTIFIED BY PASSWORD 'password' There's something wrong with my computer.. but I can't pinpoint where it is.. Thanks EDIT: It's kinda bizarre.. it goes through a VPN remotely. But if I change the internet connection, then it works.. If the previous internet connection is restored, it doesn't.. Could we classify this among the great mysteries of the world? Or someone has an idea?

• What software works well for viewing massive TIFF images on Windows 7?

  - by nhinkle

  Today I saw an article about a half-gig, 24000 square-pixel high-res composite image of the moon. (This is a much smaller version of the image) I find astronomy interesting, so I thought I'd download it and take a look. With 4GB of RAM and an i5 processor, I figured my computer could handle it. Unfortunately, the built-in Windows Picture Viewer didn't do such a great job. While it opened the file without a problem, zooming in was ineffective. The zoomed out image loaded, but zooming in just showed a scaled-up version of the zoomed-out version, not any detail: Closing the picture viewer also took a very long time, and the whole process used up much more RAM than the 500MB of the picture (usage went from 1.3GB to 3.8GB). What other software would work better for this? I would prefer something that is free and fairly simple. I don't really want to use an editor (like photoshop or GIMP), just a nice lightweight viewer. Any suggestions?

• Remote Access using Windows 7 Home Premium

  - by klelky

  I'm hoping to try and do some trans-atlantic tech support for my in-laws. Both my machine and theirs are running Windows 7 Home Premium. I read in this HowToGeek article that the Home editions of Windows 7 and Vista don't support remote access. What's the most straightforward way for me to access their machine - bearing in mind that they are a retired couple and this is their first computer and therefore anything that needs to happen at their end needs to be super simple. Free would be prefered but if there is a good paid for solution I'd consider it.

• How to Create a shortcut to files / folders on a drive with different / changing letters (root)?

  - by Rolo

  I have seen this question asked and answered many times but the location one usually desires to create the shortcut is on the actual drive with the different letters. I would like to create the shortcut on the drive with the permanent letter. So, let me explain further. I have a C Drive and a G Drive. The C Drive is always C and it's on a Windows XP computer. The G drive may be G today, but H tomorrow. How can I create a permanently working shortcut on the C Drive that points to the G, sometimes H, external hard drive? P.S. I am referring to an external hard drive, but I would also (not instead) be interested in the answer if it were a usb flash drive. (Keep in mind the shortcut is being created on the drive with the permanent letter). Thanks.

• First request too slow even if I have a load balancer in the back

  - by adrian7

  I have an Apache 2 on Centos + bind with a wordpress website on it (e.g example.com). I have also set up, on another server in a different contry a load balancer (varnish:80 + nginx 127.0.0.1:8080) for it - which task is to server all static content under /wp-content/. Using Simple DNS editor I added an A entry to cdn.example.com pointing to the server's IP. So no extra work from a 2nd dns server. Then using htaccess I redirect all requests to jpg|gif|css|js files to cdn.example.com. That works and all files are saved on the "cdn" server and served right away. My problem is that for the first time I enter on example.com (e.g after restarting the computer or closing the browser) the load time is 1 up to 3 seconds, while any subsequent page loads take only 300 to 600 miliseconds. I know it might be a DNS issue, but I have done a cache check on several websites and cdn.example.com indicates the right IP. Do you have any ideas where I should dig to solve this first-time slowness?

• Ubuntu 12.04 won't shut down - stopping winbind daemon

  - by jan

  My Precise Pangolin sometimes won't shut down - the screen is black with text on it. Mostly last line says something like "stopping winbind deamon" (sometimes also virtualbox, which is above winbind daemon; edit: sometimes the last line says "running unattended updates") and it stays like this for about ten miutes. Then I usually hold the power button for 5s to shut it down. It's very unpredictable - sometimes the computer shuts down without problem and sometimes it hangs. I've tried many ways to shut it down: HW button, panel applet, sudo shutdown -h now, sudo poweroff, sudo halt, etc. even sudo reboot or restart from panel applet have this problem. Sometimes it works ok but every method named hung at least once on the same (damned) line. My specs: FUJITSU SIEMENS LIFEBOOK E8310, Intel Core2 Duo T7300 @ 2.00GHz, 3GB RAM, GPU: Mobile Intel(R) 965 Express Chipset Family Ubuntu 12.04.2 32bit, 3.5.0-41-generic kernel (but it did it on older kernels and 12.04.x systems too). Any ideas what should I try next? Thanks a lot! Jan

• My windows keyboard is being "clever" with the quote keys - how can I stop it?

  - by Marcin

  I'm using windows 7 on a laptop. On the laptop keyboard, for some reason, the quote key (which has both double and single quote on it) is doing some "clever" annoying things: When I press single-quote (or double-quote), windows doesn't send any characters until I press it twice (resulting in '' or "") When I press it before a vowel, I get some kind of accented character. As I usually only write English, this is annoying. The backtick/tilde key is subject to similar behaviour. I have not attempted to set up my computer to process anything other than English. My keyboard appears to be (in so far as these things are standard on laptops) a standard US qwerty keyboard. How can I stop this happening?

• Ubuntu 10 installer stops after asking for username and password

  - by Jorn

  I am trying to install Ubuntu 10.10. It's running fine, until I get to the step where it asks me to specify my name, computer name, user name and password. I have filled in all those fields and all of them display a green checkmark. However, the Forward button doesn't enable. The installer continues copying files, and when it's done it says Ready when you are... in the status bar. Still, Forward is disabled. Anyone know what the problem could be?

• How can I create an orthographic display that handles different screen dimensions?

  - by Piku

  I'm trying to create an iPad/iPhone game using GLES2.0 that contains a 3D scene with a heads-up-display/GUI overlaid on the top. However, this problem would also apply if I were to port my game to a computer and run the game in a resizable window, or allow the user to change screen resolutions... When trying to make the 2D GUI/HUD work I've made the assumption that all I'm really doing is drawing a load of 2D textured 'quads' on the screen and am trying to treat the orthographic projection as an old-style 2D display with 0,0 in the upper left and screenWidth,ScreenHeight in the lower right. This causes me all sorts of confusion when I rotate my ipad into Landscape mode since I can't work out what to put into my projection and modelview matrices to turn everything around the right way. It also gets messy if I want to support the iPad's large screen, an iPhone or a Retina display since I have to then draw three sets of textures for everything and work out which ones to use. Should I be trying to map the 2D OpenGL co-ords 1:1 with the screen? While typing out this question it occurs to me that I could keep my origin in the centre, still running -1/+1 along the axes. This would let me scale my 2D content appropriately on the different screen sizes, but wouldn't I end up with the textures being scaled and possibly losing quality? I'm using OpenGLES 2.0 and have a matrix library that has equivalents to the GLES1.1 glOrthof() and glFrustrum() calls.

• Can't start firewall or automatic updates in Windows XP

  - by Chris Porter

  On a friends laptop following some viruses infestations there is a problem in starting the Windows firewall. The error is: Could not start the Windows Firewall/Internet Connection Sharing(ICS) service on Local Computer. Error 2: The system cannot find the file specified When attempting to turn on automatic updates in the security centre, the message is: We're sorry. The Security Center could not change your Automatic Updates settings. To try changing these settings yourself, go to System in Control Panel. On the Automtic Updates tab, select Automatic (recommended), and then click OK. All the options under "Automatic Updates" are greyed out. I've tried the suggestions below and many others: http://windowsxp.mvps.org/sharedaccess.htm http://support.Microsoft.com/kb/892199 http://windowsxp.mvps.org/repairwmi.htm I can't do a repair install because the installer doesn't detect existing versions. It's XP pro service pack 3.

• Outlook 2007 attachments wont preview

  - by Slace

  When I get an email with an attachment in Outlook 2007 that I should be able to preview (ie - image, word doc, etc) I get the following error: This file cannot be previewed because of an error in the following previewer: Microsoft Outlook image previewer To open this file in its own program double-click it. (obviously the previewer changes name depending on the type) The computer is a clean install (it's only 5 days old) and I remember I was at one point able to preview within Outlook. I'd really like this feature to be back working, I've tried the usual exit Outlook, restart Windows, etc but to no avail.

• print job doesn't go to print queue

  - by flatsguide

  I have two printers hooked up to my intel imac. I am having a printing error. It seems that whenever i try to print (a simple text doc) I am unable to get the print job to go to print queue with one of my printers. I have a HP c7280 and a HP c3100. I am able to get one working properly, but the other doesn't seem to allow it to go to the print queue. I have switched usb cables (with the printer that I know works) and both printers are recognized by the computer in the printer preferences pane. I've tried reseting the printer system in the printer setup utility.. reloaded the drivers from HP.. etc. If anyone has a suggestion or could point me to a little help i'd be VERY grateful Best Regards..

• Looking for internet traffic manager software for Windows 7

  - by Semyon Perepelitsa

  I have 128 KB/s (1 Mbit/s) internet connection. Not quite fast for downloading big files, but it is okay for internet browsing. When I start big file dowload, I cannot surf the web normally: pages appears slowly, especially pictures there. Therefore I pause downloading, but I'm regularly spending much time on reading articles or leaving the computer alone, when I can allow the file being dowloaded. Is there any software that can automize the process of pausing and resuming download or simply automatically regulate internet speed for each application using Internet? I download files using different software and protocols (Download Master for http, ftp; uTorrent for torrents; many other programs for updating themselves), so I don't want to be tied to particular program for downloading.

• Trouble dual booting Ubuntu 14.04 & Windows 8

  - by AkBKukU

  My motherboard (MSI G45-Z87) has efi, I still can't figure out how to make stuff work with it. I had Ubuntu working with Windows 8 before 14.04 came out and I did a clean install of Ubuntu when it did to upgrade. Since then I hadn't been able to boot Windows but I don't use it anyway so it didn't effect me. I tried getting it working today so I could use some adobe software. The last time I had tried to do something with the boot it was giving me warnings that my boot files were to far in the drive. So I followed this guide to use gparted and boot-repair to add a boot partition. I was able to reboot Ubuntu after that. I then proceeded to install Windows 8.1 to a different drive. Now the computer will only boot straight into Windows and if I manually select Ubuntu, but not the drive Ubuntu is on, to boot it stops on a black screen during boot after showing the Ubuntu logo. I've run boot-repair in several different ways but have had no luck. Here is the boot summary info from the recommended settings for it. I could really use some help.

• ifconfig can't see USB wireless

  - by Alex

  I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

• Is it possible to use different keyboards for different applications?

  - by Paperflyer

  What I would like is this: I would have two keyboards. One of them is "connected" to Matlab, the other is "connected" to my text editor of choice. This way, I could edit some script and still test some commands in Matlab without having to constantly switch between the applications. Basically, I would want to have an additional keyboard attached to my computer that solely controlled Matlab. That would be awesome! Is there any way to do this? Preferably with OSX, but it would be fun on Windows or Linux, too.

• How do I use an API?

  - by GRardB

  Background I have no idea how to use an API. I know that all APIs are different, but I've been doing research and I don't fully understand the documentation that comes along with them. There's a programming competition at my university in a month and a half that I want to compete in (revolved around APIs) but nobody on my team has ever used one. We're computer science majors, so we have experience programming, but we've just never been exposed to an API. I tried looking at Twitter's documentation, but I'm lost. Would anyone be able to give me some tips on how to get started? Maybe a very easy API with examples, or explaining essential things about common elements of different APIs? I don't need a full-blown tutorial on Stack Overflow; I just need to be pointed in the right direction. Update The programming languages that I'm most fluent in are C (simple text editor usually) and Java (Eclipse). In an attempt to be more specific with my question: I understand that APIs (and yes, external libraries are what I was referring to) are simply sets of functions. Question I guess what I'm trying to ask is how I would go about accessing those functions. Do I need to download specific files and include them in my programs, or do they need to be accessed remotely, etc.?

• Windows app that can stream video over local net with remote browsing

  - by Nifle

  What I want: An app that runs on a windows 7 computer that can stream movies to the other computers in the house. I want to be able to brows the movies on my "server" from the other computers and start streaming. I'm aware that VLC can do some (all?) of this but it's looks to complicated for my 6year old to use. Ideally I'd like something "Air Video Server" but for mac/win computers with a native client for browsing the movies on the PC running as server.

• Auto-connect Bluetooth headphones in Windows 7 64bit

  - by CptSkippy

  I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?

• What could be wrong with my CD drive and how do you fix it?

  - by Jamie

  My CD drive hasn't worked in about 8 months. I was burning CDs in a hurry and pulled it out because it was taking too long (probably an average amount of time). Im running a laptop (Toshiba Satellite A505-6965) that uses a slot drive. Now my computer doesn't accept CDs. It used to pull them in but it doesn't anymore. Ive heard it make odd noises a few times but thats it. The slot is these spongey things and Ive managed to peek into the drive with a flashlight and theres nothing in the way, really. Could someone explain the mechanics of what happened and if it would be possible to fix it? If itd be possible to fix it through Linux that would be great since I keep getting the BSOD (0x0000007B) and am going to try reinstalling Windows 7. But I can't really do that since I don't have a USB drive larger than 2 GB (Windows is about 4 GB) so Im relying on Linux ATM.

• A software to lock regions of a screen to prevent any windows from overlapping

  - by cybervaldez

  I've just installed nexus dock (a similar application like rocketdock), after playing with the preferences i've come across a very curious option (under position & behavior) that says: Prevent maximized windows from overlapping the dock. With it enabled, any application I maximize(and i do mean any) won't overlap the dock, it's really great. So i'm thinking perhaps there's a software that does this kind of feature which is really ideal for keeping my workspace really organized. I really hate repositioning and resizing my windows everytime. Of course there's always the manual way of doing these but it's just too much of a bother when someone from the family uses the computer. Do you know any software that does this? even a software that can just save/remember window positions would also be nice too.

• How to create a filesystem mountable by windows in linux?

  - by wcoenen

  I have attached an external USB disk to my debian gnu/linux system. The disk showed up as device /dev/sdc, and I prepared it like this: created a single partition with fdisk /dev/sdc (and some more commands in the interactive session that follows) formatted the partition with mkfs.msdos /dev/sdc1 If I then attach the USB disk to a Windows XP or Vista system, then no new drive becomes available. The disk and its partition show up fine in the disk managment tool under "computer management", but apparently the file system in the partition is not recognized. How do I create a FAT32 file system which can actually be used in windows? edit: I've given up on this and went with a NTFS file system created by windows. In debian lenny this can be mounted read-write but apparently it requires you to install the "ntfs-3g" package and explicitly pass the -t ntfs-3g option to the mount command.
