• Distribution upgrade freezes

  - by lugte098

  When upgrading from Ubuntu 10.04 to 10.10 the distribution upgrade program freezes after it notifies me of a change in /etc/apparmor.d/usr.bin.mysqld and asks me to keep the old file or accept the new changes (I accepted them). The terminal says: Configuration file `/etc/apparmor.d/usr.sbin.mysqld' ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. *** usr.sbin.mysqld (Y/I/N/O/D/Z) [default=N] ? y Installing new version of config file /etc/apparmor.d/usr.sbin.mysqld ... The program hasn't done anything after this for about 2 hours now and I have no idea what I should do at this point. Can I quit the program and restart it? Or is there another action I should take? It did however change the '/etc/apparmor.d/usr.sbin.mysqld' to the new version, but is still frozen...

• What's the best way to install mod-wsgi for a specific version of python (2.7) on Debian (squeeze)?

  - by Pascal Polleunus

  System info: Debian Squeeze Python versions: 2.6.6 (default) & 2.7.2 mod-wsgi: 3.3-2 in /usr/lib/apache2/modules: mod_wsgi.so -> mod_wsgi.so-2.6 mod_wsgi.so-2.5 mod_wsgi.so-2.6 I've a virtualenv configured with Python 2.7 but my application runs 2.6.6, apparently because mod-wsgi is using the default version of the system. The way to go seems to configure mod-wsgi to use 2.7 (i.e. system-wide, not specific to a virtualenv). How can I install mod_wsgi.so-2.7? After installing that, I'll just have to change the symlink mod_wsgi.so to mod_wsgi.so-2.7.

• Small font all 'new' messages suddenly in Gmail on Ubuntu in Opera, why?

  - by Michael Durrant

  This seemed to happen out of the blue. I have been using Opera for years. I can't find anywhere in Gmail to change the default font that is used in Opera. Ubuntu is Version 11 Opera is version 11.6 In Firefox the font is normal size. I have tried playing around with both all the browser setting I can find plus Ubuntu system settings (I had seen some mentions of Opera using the system default font sometimes) but no success so far. Really bumming as I have been using Opera for two years and if I can't resolve it I will not be able to use it. I can switch to Firefox but I don't want to.

• What do ptLineDist and relativeCCW do?

  - by Fasih Khatib

  I saw these methods in the Line2D Java Docs but did not understand what they do? Javadoc for ptLineDist says: Returns the distance from a point to this line. The distance measured is the distance between the specified point and the closest point on the infinitely-extended line defined by this Line2D. If the specified point intersects the line, this method returns 0.0 Doc for relativeCCW says: Returns an indicator of where the specified point (PX, PY) lies with respect to the line segment from (X1, Y1) to (X2, Y2). The return value can be either 1, -1, or 0 and indicates in which direction the specified line must pivot around its first endpoint, (X1, Y1), in order to point at the specified point (PX, PY). A return value of 1 indicates that the line segment must turn in the direction that takes the positive X axis towards the negative Y axis. In the default coordinate system used by Java 2D, this direction is counterclockwise. A return value of -1 indicates that the line segment must turn in the direction that takes the positive X axis towards the positive Y axis. In the default coordinate system, this direction is clockwise. A return value of 0 indicates that the point lies exactly on the line segment. Note that an indicator value of 0 is rare and not useful for determining colinearity because of floating point rounding issues. If the point is colinear with the line segment, but not between the endpoints, then the value will be -1 if the point lies "beyond (X1, Y1)" or 1 if the point lies "beyond (X2, Y2)".

• Windows Azure Error: Failed to start Storage Emulator: the SQL Server instance ‘localhost\SQLExpress’ could not be found

  - by DigiMortal

  When running some of your Windows Azure applications when storage emulator is not configured you may get the following error: "Windows Azure Tools: Failed to initialize Windows Azure storage emulator. Unable to start Development Storage. Failed to start Storage Emulator: the SQL Server instance ‘localhost\SQLExpress’ could not be found.   Please configure the SQL Server instance for Storage Emulator using the ‘DSInit’ utility in the Windows Azure SDK.". Here’s how to solve this problem. You need to run DSInit utility to create database. For Windows Azure SDK 1.6 the location for DSInit utility is: C:\Program Files\Windows Azure Emulator\emulator\devstore By default DSInit expects that your database server is (local)\SQLEXPRESS but you can change it easily. If you have MSSQL instance called SQLEXPRESS then it is enough to just run DSInit. If you need some other instance then run the following command: DSInit /sqlinstance:<instance name> For default instance use “.” as instance name: DSInit /sqlinstance:. You can find more information about sqlinstance and other switches from DSInit documentation. If database was correctly created you should see dialog like this: When storage database is ready you can run your application.

• How do I create the "Gnome-Desktop-Item-Edit" program's launch icon with root privileges and more?

  - by GanZ

  I personally dont prefer running commands in terminal to achieve a task and prefer apps to execute the job. Creating launcher for apps is one such command where I prefer the gnome-desktop-item-edit application for creating launchers. If the gnome package is installed, just searching "create launcher" opens the app. But, it doesnt serve any purpose, because for starters the application cannot create launchers for various apps without root permission and the location where the apps have to be created. Usually the launcher apps with root permission can be created at /usr/share/applications and without root permission at /.local/share/applications. I dont prefer the latter location as it is vulnerable to deletion. Hence, in order to create the launchers through gnome with root, everytime I am forced to open this through terminal using the below command! $ sudo gnome-desktop-item-edit ~/.local/share/applications --create-new I dont want to open terminal everytime I want to create an application launcher on unity! I am able to lock the "Create Launcher" App in the Launcher, but not with root privileges So I want to be able to create the "Create Launcher" app shortcut on unity with default root privileges and for the app to create the launchers at usr/share/applications by default! Please help! P.S. I dont have enough rep points to add screenshots to help with the question!

• Restrict only some plugins to specific sites in Google Chrome

  - by Christian

  I am looking for a way to set up Google Chrome so that it will run a certain plug-in (Java, what else?) only on whitelisted sites, but other plug-ins (like the PDF viewer) everywhere. From playing with the policies available for Chrome, I think there are basically two levels of plug-in management: List of disabled plugins/enabled plugins: Controls whether a plug-in exists for the browser at all This pair of policies applies to plug-ins, but not to sites. Default plug-in settings/Allow plug-ins on sites: Controls on which sites plug-ins can run This set of policies applies to sites, but not to individual plugins, and it cannot override the first pair. There appears to be no way to configure Chrome so that some plug-ins only run on whitelisted sites, but others run everywhere by default. I have also looked at filtering content on the firewall/proxy level, but I'm not convinced it can be done securely there. Filtering by URLs (file names) or content types can be circumvented trivially, and identification by content inspection cannot be safe either.

• macports apache,php,db, how do I test on another device?

  - by brokenindexfinger

  My supervisor suggests using macports to install/manage different versions of apache and php, as well as both mysql and posgres databases. The idea is that we need to test our platform on different versions of each. So far I've just been using the default apache installation on osx lion, and the default postgres installation. My question is this: once I turn Web Sharing off, and proceed with a custom apache2 setup based in /opt/local/, how do I broadcast my machine's IP to other devices, for testing? With Web Sharing, I can get my machine's IP and use that to test with an iPad and iPhone. Will that still be the case, and if so, how do I do it?

• Is 50% download speed on a wireless G network normal?

  - by Bartlomiej Skwira

  I have a wired connection of about 36Mb/s, but my wireless speed is max at about 18-19Mb/s. I have a WRT54G-TM (T-Mobile, 802.11G) router with DD-WRT firmware - I've upgraded it to latest build. Done some settings changes: changed channel - 13 wireless network mode - G-only ACK Timing - 0 Fragmentation Threshold and RTS Threshold - 2304 Basic Rate - All Signal/Noise ratio: -46/-94, signal quality ~50-60%. Is this normal with G networks? Edit: The AP is located about 2 meters from laptop, no walls or metal objects, but its next to a TV. I've done a channel scan (had problems locating it, go to "Status - Wireless - Site survey" - lame naming) and everybody else is on channels 1 and 6. Switched to channel 11 but it didn't help. As for trasmit power I got best results with default 71mw. The antenna might be a factor, I'm using the default 2 antennas.

• Is there a way to adjust colors of a specific window?

  - by Synetech

  Is there a (Windows) program or something that will allow the user to adjust the brightness/contrast/gamma of a specific window rather than the whole screen? As a use-case scenario, imagine having a web-page showing on one half of the screen, and another program taking up the rest of the screen. This other program uses the default Windows colors (e.g., white background), so it may be glaringly bright. Alternately, the web-page may be too dark to see. Adjusting the monitor or video-card settings would affect everything which will be no good. Adjusting the default Windows colors is, at best, inconvenient. Instead, there needs to be a way to set the colors of one of the windows to equalize the whole screen.

• ATI 9550 shows up as laptop in displays after update to 12.04, how do I fix this?

  - by D_H

  My guess is this is on here somewhere but I have searched and even tried looking at bunch of other similar video problems. My ATI 9550 shows up as laptop in displays after update to Ubuntu 12.04, how do I fix this? I found the following command on another post sudo lshw -c video. I get this when I run that command: *-display:0 UNCLAIMED description: VGA compatible controller product: RV350 AS [Radeon 9550] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 66MHz capabilities: agp agp-3.0 pm vga_controller bus_master cap_list configuration: latency=32 mingnt=8 resources: memory:c0000000-cfffffff ioport:c000(size=256) memory:e5000000-e500ffff memory:e4000000-e401ffff *-display:1 UNCLAIMED description: Display controller product: RV350 AS [Radeon 9550] (Secondary) vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 32 bits clock: 66MHz capabilities: pm cap_list configuration: latency=32 mingnt=8 resources: memory:d0000000-dfffffff memory:e5010000-e501ffff" This way more info than the command showed in he other post and as far as I can tell right. This doesn't look to me like a laptop video would list? I also see this command xrandr, it reports this: xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024 default connected 1280x1024+0+0 0mm x 0mm 1280x1024 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0 This is what shows in displays for resolutions but only the 1280x1024 works the others produce tearing in the video. Also I should have mentioned 3D mode does not work. I have tried ATI/AMD drivers the new one won't load and older ones won't work. I found out the newer driver no longer supports the 9550.

• How to setup an Openvpn server with two gateways to internet

  - by fourat

  I have an openvpn server behind two wan interfaces: eth1 and eth2 where eth1 is the default gw and eth2 is where openvpn binds to. The problems my ovpn server is replying back to ovpn client via the default gw (through eth1) and the tcp negociation is lost before establishing any tunnel. Here's what's happening: wan client -----> eth2 ----> openvpn -----> eth1 ----> lost and not delivered back to client Is there a way to tell ovpn to stick on eth2 and consider it for all traffic ?

• Per-user vhost logging

  I have a working per-user virtual host configuration with Apache, but I would like each user to have access to the logs for his virtual hosts.

• How can I redirect HTTPS(S) traffic to anothr gateway?

  - by PsyStyle

  I have a network like 192.168.0.0/15 with the default gateway set to 192.168.0.1. Al the workstations of the network use this gateway for all kind of accesses to the Internet. Now I am testing a new Internet connection with another provider and for this I am using a second gateway on the same subnet with 192.168.0.2 as IP address. I want to redirect only HTTP and HTTPS traffic to this second gateway without touching the address of the default gateway set inside every workstation. How can I accomplish this task? What I have to change inside the first's gateway firewall configuration or routes? I tried with a dnat like DNAT loc:192.168.0.1 loc:192.168.0.2 tcp 80 but nothing worked. I use Shorewall for simplicity in configuration but I can understand even theorical answers which I will try to adapt to my case

• How to connect another computer to the router

  - by Call Me Dummy

  I already have a Windows 7 PC connected to my NETGEAR WGR614v10 router and I am able to use internet in that computer. Now I need to connect one of my old computer to the router to share the internet. It's also running Windows 7. I already connected it to the router via a CAT-5 cable but I am not able to use internet. The first computer was set up by a technician. Its IP address is 192.168.1.3, and the default gateway is 192.168.1.1. On the second PC, I changed the IPv4 to 192.168.1.4 and default gateway and preferred DNS to 192.168.1.1, but it's not working. What can I do?

• Even distribution through a chain of resources

  - by ClosetGeek

  I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

• How do developers find the time to stay on top of latest technologies?

  - by u2sonderzug

  I was a freelance web developer until circa 2004 when I started going down the management route but have decided to try to get back into development again (specifically JavaScript and HTML5 web/mobile web apps) and I really get the impression to be truly good at these and similar fast moving technologies a constant amount of time is required to be set aside to invest in getting better at existing skills in addition to learning new skills. I understand right now since I am getting back into things there is a pretty steep learning curve, but seeing how good many guys are out there - the only way I see of getting up there is putting in a serious amount of time. For those working as fulltime developers, what I am trying to understand is this - on most days, how much time in the office is spent actually grinding out code compared to learning/research. I could easily spend 2-4 hours daily getting on top of the best ways to go about doing things. Do most good developers who are employed full time invest significant hours outside of work sharpening their skills? Or maybe I'm looking at all of this completely wrong?

• Gentoo+urxvt+terminus: How do I change font version?

  - by gaidal

  In my Debian installation I can type extended ASCII characters such as åäö by default using the terminus font, however in Gentoo I can't get it to work so far. Nothing happens when I hit those keys, like in this thread: Missing glyphs in Terminus font, how to setup a fallback font ? But in this case I know terminus supports those characters in at least some of its versions, since it's works in Debian. So what I want is to find out how to see and choose which of the many different terminus font files is being used. I set the font in the same way on both Debian and Gentoo, using URxvt*font: xft:terminus:size=xx in .Xdefaults. Both systems use en_US.UTF-8 as default locale.

• Hooking domain to home server (WinServer2008) with specific port

  - by user1071461

  Alright, I'm asking two things here. First of all, if i purchase a domain let's say myhomeserver.com, am I able to make the default port go through a different port instead of the default port 80? (that is without having to do myhomeserver.com:5000 for example). Also this should be without blocking other ports (so no stealth forwarding to myhomeserver.com:5000 i think) Secondly, How could I go about hooking a domain to a windows 2008 server? I've seen it on linux but no clue how to do it on windows if it's even possible. I know I'm asking a lot here, just some tips are appereciated. Also, yes I know, using a home server is horrible for security and preformance and whatnot, I understand this already, thanks ^^

• User cannot book a room resource

  Im having a problem with a specific user not being able to book a room resource. No error message is generated at all. The user attempts to add the room as a meeting resource and it simply doesnt register with the resources calendar. I have tested the resource with other accounts and other rooms for this user but it is only this room that is having issues for this user. This Exchange server was migrated from 2007 to 2010. All rooms except for the problem room were created back on Exchange 2007. This new room was created with Exchange 2010. Maybe this clue has something to do with the problem?
