• Apache/passenger/ree doesn't interpret .rb files

  - by Sergey

  I'm trying to get apache + passenger + ree to work. I think I did everything (except for setting up rails env - for now I wanna run just pure ruby) described here: http://rvm.beginrescueend.com/integration/passenger/ But when I try to go to localhost/test.rb it doesn't interpret that file and just download it. I don't know where should I look for mistakes, so here are a few files I think could be relevant: /var/log/apache2/error.log (these 2 lines are repeating) [Mon May 31 23:12:47 2010] [notice] Graceful restart requested, doing restart [Mon May 31 23:12:48 2010] [notice] Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.2 with Suhosin-Patch Phusion_Passenger/2.2.11 configured -- resuming normal operations /etc/apache2/httpd.conf LoadModule passenger_module /home/sergey/.rvm/gems/ree-1.8.7-2010.01/gems/passenger-2.2.11/ext/apache2/mod_passenger.so PassengerRoot /home/sergey/.rvm/gems/ree-1.8.7-2010.01/gems/passenger-2.2.11 PassengerRuby /home/sergey/.rvm/bin/passenger_ruby /var/www/test.rb puts "test"

• What is controlling the desktop display?

  - by Bart Silverstrim

  I have two Ubuntu systems and in the course of changing configurations something has become muddled. I have disabled Unity in favor of gnome shell, the older style display of the desktop. Then I installed xfce 4. Seemed everything would be working okay, and for the most part it does. Except I noticed that on one system there's something else controlling settings. On one, if I right click the desktop, I get the menu with the options: open in new window create launcher... create url link... create folder... create from template -> open terminal here paste desktop settings... properties... applications -> On system two, right clicking brings up the menu: Create new folder Create new document -> organize desktop by name keep aligned paste Change Desktop Background Additionally, even though I set the background with the xfce settings manager, on system two that background will appear for a few seconds before it's replaced by something that looks like a background from Ubuntu's original desktop. And it's being controlled by what comes up with the "change desktop background" when right clicking, which isn't the xfce settings manager. On the first system, that right click does bring up the xfce settings tool. In short, something is controlling/overriding the xfce settings on machine two, but I can't find what file or configuration tool is doing it. How can I get system two to behave as system one, giving control of settings and configuration of X to XFCE's tools?

• Create new partition on live production CentOS server

  - by Kimmel

  I have a production server that is running on CentOS. I'd like to create a partition on the server without having to reinstall everything. I have CLI and VNC access to the remote server. Is there anyway that I can create a partition safely? Here's my output from fdisk -l Disk /dev/sda: 85.9 GB, 85899345920 bytes 255 heads, 63 sectors/track, 10443 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00033d5e Device Boot Start End Blocks Id System /dev/sda1 * 1 10444 83885056 83 Linux Thanks.

• Does MS Forefront TMG cache authentication?

  - by SnOrfus

  I'm testing a client machine that makes requests to a biztalk server using a forefront machine as a web proxy. Upon first test I put in an invalid name/password into the receive port and received the correct error message (407). Then, I set the correct name/password and everything worked correctly. From there, I kept the correct information in the receive port but put an invalid name/password into the send adapter but the process completed successfully (should have failed with 407). I've ensured that both the recieve and send ports are not bypassing the proxy for local addresses. So the only thing that seems to make sense is if TMG is caching the authentication request coming from the machine I'm working on. Is this thinking correct, and if so, does anyone know how to disable it in TMG?

• linux ssh -X graphical applications will not start when system load is high

  - by Chrisv

  So I am using ssh -X to access a server. I am at a Xubuntu desktop accessing a Ubuntu server that is in the next room. Usually everything works fine, but when the system load gets high, any graphical applications I have freeze and fail to be restarted. This happens even if the process that is causing the high load has been niced to a low priority with "nice -n 19". And even though the system load is high, the command line works fine with no delay, and other applications I have running on the server (e.g. virtual machines) run fine. But any graphical application running through X dies. When the graphical applications fail they usually give out an error message that suggests a time-out. It seems that something connected to X has a low priority and times out. But what is it, and how does one fix it?

• Force initial Google Drive sync with a non-empty folder?

  - by Terrance Shaw

  I upgraded my iMac with an SSD last night and restored from a Time Capsule backup. Everything is now working substantially zippier and overall better, with the exception of one thing: Google Drive refuses to continue to sync with the Google Drive folder that it'd been using before the upgrade, and I ultimately ended up having to just delete the folder and let it resync from scratch to get past its stubborn error (alternatively, I suppose I could've simply moved the contents, set the path to the now-empty folder, then moved them back). Is there any way to get past this particular issue (for future reference), or is it something that Google put in place to ensure that a new user doesn't go and specify their root drive as the backup destination?

• VPN only connects to its server!

  - by Eddie

  Hi guys; Previously I bought a windows 2003 VPS and enabled routing and remote access so that users can make a vpn connection. I turend the firewall off and everything was working fine. But since 2 days ago whenever I try and connect to vpn it connects to vpn without any problem and I can see the connection status however it only connects to the server I mean what I can do with this vpn is to connect to the server via remote desktop and I can ping only the server's IP, neither I can open any webpages in browsers or ping other IP addresses beside the server one! I've also rebuilt the server and configured it for routing access and vpn connection from the beginning but it doesn't work either. It seems that server fails to route the traffic properly, as i'm sure that the firewall has been turned off I can't figure out what's the reason, any idea what's going on? Thanks in advance

• Attempting to migrate to Aptana from Dreamweaver - how to?

  - by Kerry

  I have been using Dreamweaver for years, and have used Dreamweaver MX, Dreamweaver MX 2004, Dreamweaver 8 & Dreamweaver CS4. They all carry a common theme and were relatively easy to migrate to each other. I use, however, very few features of dreamweaver. Specifically: Syntax highlighting Telesense FTP management/site management The search/replace The idea I get from Aptana is its much more geared toward the web development/programmer side of things, have better visualizations of classes, etc., and handle everything else just as well. The problem is it is not at all clear to me. I managed to start a new project, but it didn't associate it with an FTP. So, I created an FTP, and it looks like I can have many FTPs for one project. My question then is, is there a tutorial or guide to migrating to Aptana from a Dreamweavor's perspective?

• Damaged XenServer Storage LVM partition table

  - by Fiolek

  I have a homeserver running under XenServer control with 3x1TB discs inside, one for XenServer and two mirrored(using Intel's fakeRAID and dmraid) for VMs and a user data(but now I think RAID didn't work). I tried to pass PCI card to VM using PCI-passthroug and I read somewhere that I need to recompile kernel with pciback module but something went wrong(I made mistake in /boot/extlinux.conf and server couldn't run) and I had to use LiveCD of GPartEd(I already had it on USB key) to correct this. But when I re-run the server all VDIs were gone. I have completly no idea what could go wrong. I tried to repair RAID using dmraid -R in the hope that everything will return to noramal but now I think this done more bad than good(and corrupted rest of LVM table...). Is there any possibility to recover this SR or only data from one(~100GB) of VDI? I also wants to apologise for my English, I'm not from English-speaking country and I'm only 16 years old, so I hadn't "time" to learn it(school isn't good place to do this) in sufficient way.

• graphics-card makes sound-card produce a buzzing sound

  - by Markus von Broady

  Recently I bought a new GPU: GeForce GTX 550 Ti, and after installing it I get a strange buzzing sound. It's not always there, just sometimes (mostly when I open some game, but sometimes also in browsers etc.). It's not a capacitor or a fan, as unplugging speakers from sound-card makes the 'bzzzzzzz' go away. However, muting windows doesn't mute this sound. I'm pretty sure it is fault of the new GPU, but how is this happening and can I fix it? Can it be a low power supply? I thought of buying a stronger unit, but as everything works, and computer doesn't shut down, I hesitate.

• NX Client running on OS X 10.6.3 => NX Server Ubuntu 10.04: weird keymapping issue

  - by Mike D

  I have been using Ubuntu 9.10 at work after switching from vista. After being (expectedly) disappointed with performance over VNC (via VPN) when logging in from home, I came across the NOMACHINE suite. Last week, I upgraded from OS X 10.6.2 = 10.6.3 at home. After that, I also updated my NX Client at home to the latest version, as there were issues with recent changes in the OSX X11 setup that rendered the NX connection useless. At that point, everything worked fine. Fast forward, I upgraded from 9.10 = 10.04 on my work machine the next day, and after coming home and trying to log-in remotely, I noticed that the "s" and "m" keys, when pressed locally, acted as if the meta key was being pressed on the remote machine. That is, the "s" key opens in the Ubuntu login menu (the power icon), and the "m" key opens the messaging menu. I found some info on using xmodmap to remap keys, however, I can't even begin to fathom what keys I could remap to solve this issue. Any ideas?

• Apache mod_rewrite for multiple domains to SSL

  - by Aaron Vegh

  Hi there, I'm running a web service that will allow people to create their own "instances" of my application, running under their own domain. These people will create an A record to forward a subdomain of their main domain to my server. The problem is that my server runs everything under SSL. So in my configuration for port 80, I have the following: <VirtualHost *:80> ServerName mydomain.com ServerAlias www.mydomain.com RewriteEngine On RewriteCond %{HTTPS} !=on RewriteRule /(.*) https://mydomain.com/$1 [R=301] </VirtualHost> This has worked well to forward all requests from the http: to https: domain. But as I said, I now need to let any domain automatically forward to the secure version of itself. Is there a rewrite rule that will let me take the incoming domain and rewrite it to the https version of same? So that the following matches would occur: http://some.otherdomain.com -> https://some.otherdomain.com http://evenanotherdomain.com -> https://evenanotherdomain.com Thanks for your help! Apache mod_rewrite makes my brain hurt. Aaron.

• PIN based Login in Windows 8.1 Missing

  - by WiredPrairie

  I installed a fresh copy of Windows 8.1 Pro using Hyper-V, and updated with all updates via Windows Update. It's not domain joined. I cannot however activate a PIN based login for the installation and I'm not sure why. I'm using a Microsoft account to login (not just a local login). I have even manually enabled the feature using group policy (which apparently only should have mattered for a domain joined workstation anyway), rebooted, and it's still not available. As far as I can tell, everything else seems normal and is working as expected. For Sign-in options, I only see Password as a choice:

• How to install Mac OS X from Windows without a CD

  - by John Smith

  I have two partitions, one for windows the other for Mac OS X. Recently, my Mac OS X crashed and my partition rendered unbootable. When I insert Mac OS X's installation CD everything seems normal from startup, to choosing whether to boot from Windows or CD, until the CD boots. The screen flickers and it becomes extremely dark can barely see anything but I can see that it is booted correctly. I tried increasing brightness but that did not work. After hours of trying to read what is on the screen and guessing where to click the installation did not go through... It took more than a couple of hours so I restarted. Now the partition is accessible through Windows but is not bootable. TL;DR Is it possible to install Mac OS X on a visible partition without the CD through Windows XP?... Thanks

• Poor System performance on my machine running Ubuntu 12.04(Beta 2 updated to the present moment)

  - by Mohammad Kamil Nadeem

  Why is it that my system dies when multitasking(it is happening from 11.10) on Ubuntu11.10(Unity), Kubuntu 11.10(KDE) and Deepin Linux which is based on 11.10(Gnome-Shell) The thing is that I thought with 12.04 I would get performance like I used to get on 11.04 on which everything used to run fine without any lag or hiccups. The same lagging(Browser starts to stutter, increased delay in the launching of dash and applications)is happening on 12.04 http://i.imgur.com/YChKB.png and http://i.imgur.com/uyXLA.png . I believe that my system configuration is sufficient for running Ubuntu as you can check here http://paste.ubuntu.com/929734/ . I had the Google voice and chat plugin installed on 12.04 so someone suggested that I should remove that and see if the performance improves but no such respite(I am having this on multiple operating system based on Ubuntu 11.10 as I have mentioned above). On a friends suggestion Ran Memory Test through Partition Magic and my system passed that fine. One thing more that I would like to know is that why when I have 2Gb Ram and 2.1GB swap does my system starts lag and run poorly when Ram consumption goes 500+. If you require anymore information I will gladly provide it.

• How to install python modules for specific python version

  - by Zayatzz

  I needed to install UCS2 python next to UCS4 python. So I went to comp.lang.python and asked them about it. Probably not the best place to ask it, but they answered https://groups.google.com/forum/?fromgroups#!topic/comp.lang.python/bGuAfqa76W8 and now i have brand new python 2.7.3 ucs2 installed in /opt/bin/python What I need now is - how can I install all other python modules that I have installed for that python version also. Basically stuff like PIL and postgresql and mod_wsgi - basically everything needed to run Django for that python version. Is this the right the place to ask for it?

• Unable to connect to local SQL Express (2008)

  - by Will

  I'm trying to get an installation of SQL Express 2008 working, but no matter what I do I can't connect to it with management studio. I've enabled TCP/IP for the instance. I've tried connecting with machinename\instance, .\instance, (local), etc etc etc. Nothing works, and I always get the same message. If I browse for a server, the only server listed is the local integration services, which I can connect to just fine. The SQL server service is running (SQLEXPRESS), SQL Server Agent is not (and won't, can't enable it), and SQL Server Browser is. Anyone have any suggestions on where to go next? I've tried uninstalling EVERYTHING sql and reinstalling, no change.

• Unable to find a disable button for pop-up bubbles in 2.8.0.851

  - by Greg Richards

  I'm still using 2.8.0.722 on my Mac while a friend has upgraded to 2.8.0.851 The newer version on her computer has pop-up bubbles for every chat message when the chat window is minimized. Neither of us are able to find where to disable this feature. The difficulty arises when we minimize a chat window, but the bubbles continue to show everything the other person is typing, even when one of our kids is with us for a moment looking at something else on the screen. We have checked all throughout the Preferences settings, most notably the privacy and chat areas, to no avail. Ultimately we would like to disable these chat pop-up bubbles so that when a chat window is minimized, that conversation and all incoming messages will remain private until we restore that chat box to be viewable on the screen again. Thanks! Greg

• Firefox does not print flash content

  - by Rochelle

  I am using Firefox 3.6.15 on a Windows 7 Professional, 64-bit Operating System, Intel Core i7 CPU, 3.33GHz, 10BG RAM, by Hewlett-Packard. Firefox does not print flash content, aka swf objects, nor does it show them in the print preview pane...I want to print out the entire web page with the flash content. I seem to only be able to see flash and html content together in print preview and to print in IE8. I have tried to google this issue, but could not find a solution. I was trying to print preview/print out the following site: http://www.discovertheponds.com/. Flash content will display in print preview and print in IE8, but neither print preview or print in Firefox. I have also updated the Java on my computer to the most recent update, and ran the firefox plug-in checker at http://www.mozilla.com/en-US/plugincheck/ . I do run Firebug and Web Developer, but have currently disabled them. Is this problem on my end, meaning some issue with my computer...or is this because of how the website was programmed in HTML/Flash...or is this a bug with Firefox? I am a website designer and am also concerned that others will not be able print sites I develop or have already developed that have flash content from Firefox. I used to think Firefox was better than IE at everything. What happened here? Was it some change in Firefox's version that caused this problem?

• Trying to find the life expectancy of an unused flash card like SD

  - by wsams

  I read in the What's the life expectancy of an SD card? post SD cards are rated to hold data at something like 10 years sitting idle. I recall reading (not sure where) about re-energizing cards by occasionally inserting into a reader. Everything I read rates in read/write cycles and not physical decay. I'm wonder if buying a new sd card for every photo shoot would be beneficial if I could store the cards in a lock box? I was hoping for something much longer. Does anyone else agree with 10 years or maybe something more?

• Why does terminal prompt text becomes black when connecting to Ubuntu with Nomachine NX client?

  - by David B

  I'm using Nomachine NX client for Windows to remotely connect to my Ubuntu. Every now and then I experience a strange phenomena: the text in the prompt of all open terminal windows becomes black, so it can't be viewed over the black background. Typed commands are also black, but the results are in normal colors. So I can run stuff, but can't see what I'm typing... After I close all open terminal windows and start a new terminal window, everything goes back to normal. This is rerally annoying and happens quite often. Any idea why?

• User Permissions: Daemon and User

  - by Eddie Parker

  Hello: I often run into this issue on Linux, and I'd love to know the proper way of solving it. Say I have a daemon running. In my example, I'll use LigHTTPD, a webserver. Some software, like Wordpress, enjoys having read/write access to files for updating applications via a web interface, which I think is quite handy. At the same time, I enjoy being able to hack on my files using vim, using my local user account, 'eddie'. Herein lies the rub. Either I chown everything to lighttpd or eddie and a shared group between them both, and chmod it 660, or perpetually sudo to edit the damned things. The former isn't a bad solution, until I create a new file in which case I have to remember to chmod it appropriately, or create some hack like a cron job that chmods for me. Is there an easier way of doing this? Have I overlooked something? Cheers, -e-
