• Can't ping external websites

  - by Frantumn

  I can't ping google.com with my virtual ubuntu 12.04 server. I have set up a proxy URL in my /etc/apt/apt.conf file and it says Aquire::http::proxy http://urlname.com:9999; Now, I don't know a lot about how the proxy works, but I do know when we use it on windows VMachines it's a pac script that we place in internet explorer LAN settings and it automatically detects the script and gives internet access. I tried including the 9999/proxy.pac in the apt.conf URL and it didn't seem to work any better. Would ubuntu know how to handle a proxy.pac assuming it was created for windows? Should my URL include the .pac or just end after the port numbers? I've tried both without sucess, but I would like to know. A quick test to ping a fellow co-workers' PC was sucessful. So I can see network computers, but not google. or other internet sources.

• How do I make Unity quit opening Firefox under the Shiretoko icon?

  - by Azendale

  I'm using Ubuntu 12.04, and whenever I open Firefox, whether it is from searching on the dash or clicking a 'quick-launch' launcher, it always opens yet another icon for the running instance that is a blank page and says Shiretoko. It will pulse the Firefox icon for a while (I'm guessing until a timeout or something). It's as if Unity no longer recognizes the Firefox process as Firefox and misidentifies it as Shiretoko. (I know Shiretoko was a testing version of Firefox a long time ago.) How do I set Unity straight? I imagine that it has something to do with me once using Shiretoko, but I believe that was even on a different installation, just the same home folder. Is there some place Unity caches this information that I can clear (or remove specific parts of)?

• Meta Refresh for change of page name and content

  - by user3507399

  Hopefully just a quick one. I've got a client that is changing the name of a workshop that they run. This means a change of url, page title for keywords that they have first page ranking on. The keywords are still relevant so what I want to avoid is a 301 redirect to a page that has different keywords to the previous page. Is the best option to keep the old page live with url and title and use a meta refresh to redirect after a period of time (not instant)? That way the SEO ranking is retained for the previous workshop name while they work on the ranking for the name change? Would a 301 redirect have an inverse effect? Thanks!

• Bring the Windows 8 'Start Menu' back!

  - by ihaynes

  I've been using the the Windows 8 RTM from MSDN for a week but the more of my normal software I load onto the machine the more awkward it becomes using the new 'Metro' (yes I know that name is now not used) 'Start' screen. Yes, you can oraganise your programs in groups, or you can add them to the Quick Launch bar, or you can create alphabetic folders on the desktop but sorry Microsoft, none of these are as logical as the alphabetic Start menu of previous Windows versions.Fortunately the good people at Stardock have a solution in 'Start8', which brings the Start Menu we know and love back to Windows 8. It's still in Beta and the current one runs out in October. I'm looking forward to the final release and like lots of other users, I'll be happy to pay for this.Lets hope Microsoft either reinstate the Start Menu in the first service pack or gives us a usable alternative. In the meantime, here's an excellent solution.http://www.stardock.com/products/start8/

• A simple deployment example using Oracle Solaris 11

  - by Glynn Foster

  Last week I was over in Melbourne and Sydney to present at an Oracle Technology Network System Administration Day. During a set of morning sessions, I presented on some of the new things that we've done in Oracle Solaris 11 and our focus for the future. One of the sessions I presented was giving a quick technical overview of what a typical application deployment scenario would look like using technologies like the Image Packaging System (IPS), Service Management Facility (SMF), Oracle Solaris Zones, and network virtualization. While it's just a simple example, it provides the basic building blocks for a more advanced configuration that a data center would typically deploy. Given these would likely be of general interest, I thought I'd upload the slides for others to view - enjoy! You can download the original source PPTX without some of the formatting errors in the above.

• Why does the Git community seem to ignore side-by-side diffs

  - by Kyle Heironimus

  I used to use Windows, SVN, Tortoise SVN, and Beyond Compare. It was a great combination for doing code reviews. Now I use OSX and Git. I've managed to kludge together a bash script along with Gitx and DiffMerge to come up with a barely acceptable solution. I've muddled along with this setup, and similar ones, for over a year. I've also tried using the Github diff viewer and the Gitx diff viewer, so it's not like I've not given them a chance. There are so many smart people doing great stuff with Git. Why not the side-by-side diff with the option of seeing the entire file? With people who have used both, I've never heard of anyone that likes the single +/- view better, at least for more than a quick check.

• Per fragment lighting with OpenGL 4.x tessellated model

  - by Finlaybob

  I'm experienced with OpenGL 3+. I'm dabbling with tessellation shaders and have now got to a point where I have a nicely tessellated teapot/plane demo (quick look here) As can be seen from the screenshots, the lighting is broken (though admittedly doesn't look too bad in the image) I've tried to add a normal map to the equation but it still doesn't come out right, I can calculate the normals, tangents and binormals per triangle in the geometry shader but still looks wrong. I think the question would be; How do I add per fragment lighting to a tessellated model? The teapot is 32 16-point patches, the plane is one single 16 point patch. The shaders are here, but they are a complete mess, so I don't blame anyone who cant make sense of them. But peruse at your leisure if you like. Also, if this question is more suited to be somewhere else i.e. Stack Overflow or the Programming stack please let me know.

• Lost sudo privileges

  - by Gamegoofs2

  Last night I was working on installing vsftpd on my Ubuntu 12.10 server. I shutdown last night and when I booted up this morning I seemed to have lost the abilities to sudo anything. It just says, "** is not in the sudoers file. This incident will be reported." Now I wasn't messing with any sudo files, just /etc/vsftpd.confg and /etc/shells. So how did I seemingly lose sudo ability? I'm rather new to Linux in general, but I'm picking it up quick.

• smbmount returns "operation not permitted"

  - by Petriborg

  I use the smbfs tools package to mount my SMB shares. I wrote a quick script to mount the share: #!/bin/sh /usr/bin/smbmount "\\\\somehost.local\\hostshare" /media/hostshare -o user=smbuser,dom=WORKGROUP,uid=localuser,gid=localgroup This script used to work in 9.10 when called by the "localuser" account, but in my fresh-installed 10.04 it fails giving me the error: mount error(1): Operation not permitted Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) The /media/hostshare directory is empty and has these perms: drwxrwxr-x 2 localuser localgroup 4096 2010-12-12 12:04 hostshare/ The "localuser" is in these groups: localgroup adm dialout cdrom plugdev lpadmin admin sambashare Any idea what is going on here? Google seems to suggest that the "sticky" bit needs to be set on /sbin/mount.cifs /sbin/mount.smbfs and /sbin/umount.cifs Is this a bug?

• what is the easiest way to make a hitbox that rotates with it's texture

  - by Matthew Optional Meehan

  In xna when you have a sprite that doesnt rotate it's very easy to get the four corner of a sprite to make a hitbox, but when you do a rotation the points get moved and I assume there is some kind of math that I can use to aquire them. I am using the four points to draw a rectangle that visually represents the hitboxes. I have seen some per-pixel collission examples but I can forsee they would be hard to draw a box/'convex hull' around. I have also seen physics like farseer but I'm not sure if there is a quick tutorial to do what I want. What do you guys think is the best approach becuase I am looking to complete this work by the end of the week.

• "Fatal Error" message during boot process

  - by Denja

  I'm running Ubuntu 10.10 with ATI proprietary FGLRX graphic drivers When I boot, I can see this very quick message appearing; I don't have time to read it: **Fatal Error ..................................**(&@something i cant read) I searched through the log file in /var/log/ in order to find what is wrong and I did find something in the /var/log/Xorg.1.log: 21:31:08 [ 15.734] (--) using VT number 1 [ 204.647] Fatal server error: [ 204.647] xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call [ 204.647] [ 204.647] Please consult the The X.Org Foundation support at http://wiki.x.org for help. [ 204.647] Please also check the log file at "/var/log/Xorg.1.log" for additional information. [ 204.647] But this is already Xorg.1.log. And there is a Xorg.0.log also & Xorg.0.log.old but it doesnt have any error in it. My system seems to work properly and it seems its not affected by this But how do I correct this message? Any suggestions?

• How important is index size when searching?

  - by Michael K

  My company has recently began using Apache Solr to search its data. As we learn how to use it we have gone down the path of indexing multiple fields to get the results we need. Most of these are either N-Grammed or Edge-N-Grammed. Gramming by nature takes up a lot of space, which takes more time to search. Space is cheap, but time is less so. Index time is not too important, since a delta-import (only get the changes since last index) is extremely quick and you only pay a penalty on the first import. What we've not been able to determine is what effect the index size has on query times. Obviously a larger index takes longer to search, but the time added by n-gramming a field is difficult to predict. How do you determine whether a field is worth gramming? Can you predict how much longer a query will take when you gram a field?

• Window controls missing; Cannot maximise or minimize applications

  - by omg_scout

  Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

• Is it possible to auto-mount sshfs

  - by Mark D

  Is it possible to auto-mount a remote FS using sshfs upon instantiating a proper VPN connection? Allow me to explain the scenario, I'm working remotely, to do that it helps if I can mount my home dir from a server in the office. To do that I need to vpn in. So within network manager I select the relevant VPN and connect. It connects but now I have to drop to the command line and mount my home dir on several machines. If I forget to do one machine my local dev environment isn't as efficient. I suppose I could write a quick bash script to do this but I'd rather get it running automatically when I connect.

• Setting umask globally

  - by DevSolar

  I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally, so that the X11 desktop environment gets the memo as well?

• What Application Indicators are available?

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using the Unity interface. Unity is working quite well so far but I really miss panel applets for net speed, cpu temp, and system monitor. These applets are useful for viewing quick info. Unlike 10.10, there is no other way to get this info onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know one then please list out any third party indicators with links so that they can be found.

• Google App Engine: How to be notified when APIs change or become available?

  - by herpylderp

  I am thinking about writing a GAE app but am a little hesitant because the EULA gives Google full rights to change their APIs anytime they want, for any reason. Obviously, they'd be out of business quick if they just 'upped and refactored their entire APIs, so I have to imagine they have some kind of notification system, perhaps even an RSS feed, etc. to notify developers well in advance of looming changes, or new features coming out in future releases. However, for the life of me I can't seem to find any trace of the existence of such a notification system. Perhaps the Google forums is the only place to get such updates? I guess I'm asking any battle-worn GAE veterans for re-assurance that there are reliable ways of getting notifications about policy or API changes from Google such that I could react and make the necessary app changes without production breaking or impacting any clients. Thanks in advance!

• return to middle click copy and paste ubuntu 13.10

  - by user206999

  Recent update to 13.10 left the middle mouse button turning sound on and off!! How do I get back to being able to copy and paste? Select the text then paste with the middle Wheel mouse button. This is a feature I used to use a lot and I find extremely quick and useful. I know I can use ctrl c, ctrl v, and right click select copy, select paste but this is clunky compared to just being able to click the middle wheel button. Is there a settings menu option to gain correct operation of the middle wheel button?

• How to prevent a 404 Error when creating a subdomain and using www to access it?

  - by Chris

  I have installed a multi-site installation of WordPress onto my domain. I then added the necessary code to the wp-config.php file and .htaccess as instructed by WordPress. I also installed a plugin called Quick Page/Post Redirect Plugin which allowed me to place a 301 redirect onto the main domain as I only want to use the sub domain and not the main domain. Then I also added the following line of code to the wp-config.php file to redirect the main domain define( 'NOBLOGREDIRECT', 'URL Redirect Address' ); The site works fine with a redirect on the main domain and my subdomain runs fine when you type in subdomain.example.com or http://subdomain.example.com. However when I enter www.subdomain.example.com or http://www.subdomain.example.com the following error message is returned: Not Found The requested URL / was not found on this server. Apache/2.4.9 (Unix) Server at www.subdomain.domain.com Port 80 Any help with this would be much appreciated.

• PHP or RoR... Which is simpler?

  - by foreyez

  I'd like a server side scripting language for the web either php or ror: to do some dirty simple data fetching and eventually handing it off to my ajax app. I usually use php for this but I keep hearing the ror buzz word. I'm wondering for those who have used both, which is ultimately simpler to get something quick and dirty running? I'm a bit turned off to RoR as it seems to have many files (it's more of a framework), whereas php can potentially just be one file and that's it. But maybe I'm wrong, can you clue me in?

• Best language or tool for automating tedious manual tasks [closed]

  - by Jon Hopkins

  We all have tasks that come up from time to time that we think we'd be better off scripting or automating than doing manually. Obviously some tools or languages are better for this than others - no-one (in their right mind) is doing a one off job of cross referencing a bunch of text lists their PM has just given them in assembler for instance. What one tool or language would you recommend for the sort of general quick and dirty jobs you get asked to do where time (rather than elegance) is of the essence? Background: I'm a former programmer, now development manager PM, looking to learn a new language for fun. If I'm going to learn something for fun I'd like it to be useful and this sort of use case is the most likely to come up.

• How can I disable the prefetch cache?

  - by Oli

  I run a few Ubuntu servers that have a load of django sites running on them. The sites and the httpd start at boot and after that (apart from me SSHing in to update it or using bzr to update websites) nothing else gets run on it. At the moment over half the ram is allocated as cache. This isn't a problem because cache usually makes space or a little bit of it slips into swap (again, this doesn't really bother me) but I don't see the need for it. Is there a quick way to disable the cache? This is more of an experiment than anything else so it would be handy to know how to turn it back on again.

• Ubuntu 12.04 and Realtek Wireless Card Incompatible

  - by Tim

  Quick background: I installed Linux Ubuntu 12.04 on a Dell Inspiron 3520 after uninstalling Windows 8. A friend suggested to do this as opposed to buying a laptop with Linux pre-installed. Everything except the wireless card works. When I load up the laptop, I see a wireless animation as if it's trying to locate the wireless connection (for a while, then it goes blank), but no connections appear under the wireless option (under "Edit Connections" then "Wireless"). What I've tried: - Doing ndiswrapper. Failed. - Installing a few kernels for realtek. Failed.
