• Ubuntu X doesn't start

  - by den-javamaniac

  I'm running desktop Ubuntu 9.10 on my Dell laptop. Previously it was Ubuntu 9.04. After some period of time (lets say 3-4 months) my X fails to start automatically after some restart calls. If that takes place my network manager applet doesn't start either (after I do startx). Can any one point out what I'm missing/what's the problem?

• Is there a way to create a cmd shortcut for a specific folder on W7 or/and W8?

  - by Hinstein

  Let say i have 3 different folders that i want to access with CMD C:\Users\Henok\Documents\Visual Studio 2012\Projects\TestApp1\Debug C:\Users\Henok\Documents\Visual Studio 2012\Projects\TestApp2\Debug C:\Users\Henok\Documents\Visual Studio 2012\Projects\TestApp3\Debug I wonder if there is a way to create 3 different cmd shortcuts to access those directory (folders) individually without changing the default cmd directory location. Forgive me for my broken English, and thanks for your time.

• Is it possible to run several virtual machines each with independent mouse+keyboard on a single PC?

  - by chiurox

  My goal is to instead of buying 4 separate basic PCs (plus the obvious peripherals), buy just one fast PC and the peripherals. I'm wondering if I can use a more powerful computer, say, one with core i7 and plenty of RAM, with 2 video cards (total of 4 monitor outputs) to run 4 or more virtual machines (WinXPs) so instead of having 4 individual machines, I'll be having just one. However, the catch is, is it possible to have a pair of mouse and keyboard + input/output audio for each of these virtual machines?

  - by Andrei

• <VirtualHost fqdn.mydomain.com:80> not recommended?

  - by Alois Mahdal

  In Apache2 documentation thay say that in <VirtualHost *:80>, the * can be replaced by IP or FQDN, but the FQDN is not recommended. Addr can be: The IP address of the virtual host; A fully qualified domain name for the IP address of the virtual host (not recommended); But why is it not recommended? If I have www.mydomain.com and webmail.mydomain.com pointing to the same IP address, why shouldn't I use the names here?

• Do Cpuidle governors and Cpufreq governors work in mutual exclusion ?

  - by kashyapa

  My understanding is that when a cpu is in C0 state , the cpufreq governor decides what P-state the CPU should reside in .When a CPU goes idle, it falls from C0 state to a deeper C-state. The cpuidle govenor, say menu , takes over in deciding which C-state the CPU should go to , once the CPU goes idle . Is my understanding correct ?

• Symbol LL500 Scanner Interface Not Detected

  - by agentfll

  I have an old Symbol LL500 scanner interface box and a scanner to go with it. The box's original cable used one of the old microsoft mouse connectors, but I got a converter to USB. The problem is that when I connect it to my MacBook, the interface powers up and works, but the computer dosen't recognize it or even say that a device is connected. Is there any way to make it see that the interface is there or am I just screwed?

• mass rescaling of pngs

  - by William Jockusch

  I have a bunch of png files that I want to rescale. Oversimplifying a little, let's say I have files named: [email protected] [email protected] [email protected] and so on, and I want to make: apple.png orange.png pear.png, and so on, with the output files all at half the scale of the corresponding input files. Is there a good tool for that? I have about 200 input files, so preferably the whole process would be automated.

• Is there a unix command to output time elapsed during a command?

  - by Olivier Lacan

  I love using time to find out how long a command took to execute but when dealing with commands that execute sub-commands internally (and provide output that allows you to tell when each of those sub-commands start running) it would be really great to be able to tell after what number of seconds (or milliseconds) a specific sub-command started running. When I say sub-command, really the only way to distinguish these from the outside is anything printed to standard out. Really this seems like it should be an option to time.

• Outlook 2003: How to display my own messages in conversation view?

  - by Godsmith

  When I select View-Arrange By-Conversation in Outlook 2003, the messages I sent myself are not shown in the message threads (unlike the conversation view in say, Gmail). To show my own messages I have to go to the Sent Items folder, if not someone has replied to one of my messages and included my original text. Is there a way to make my own messages visible in the conversation threads? Thank you! /Filip

• Managing hosts and iptables in scalable architecture

  - by hakunin

  Let's say I have a load balancer in front of 3 app servers. Let's say I also have these services available at certain IPs: Postgres server Redis server ElasticSearch server Memcached server 1 Memcached server 2 Memcached server 3 So that's 6 nodes at 6 different IP addresses. Naturally, every one of my 3 app servers needs to talk to these 6 servers above. Then, to make it a bit funkier, I also have 3 worker servers. And each worker also talks to the above 6 servers, but thankfully workers and apps never need to talk to each other. Now's the kicker. Everything is on Digital Ocean VPS. What that means is: you have no private network, no private IPs. You only have separate, random IP address on each machine. You can't mask them or anything. So in order to build a secure environment I would have to configure some iptables. For example: Open app servers be accessed by load balancer server Open redis, ES, PG, and each memcached servers to be accessed by each app's IP and each worker's IP This means that every time I add an app or worker I have to also reconfigure iptables in those above 6 servers to welcome the new app or worker. Is there a way to simplify this type of setup? I was thinking — what if there was a gateway machine between apps/workers and the above 6 machines. This way all the interaction would always happen via the gateway server, and when I add a new app or worker I wouldn't need to teach the 6 servers to let it in. If I went this route, then I'd hope a small 512mb server could handle that perhaps, and there wouldn't be almost any overhead. Or would there? Please help with best way to handle this situation. I would appreciate an answer as concrete as possible. I don't think this is too specific, because this general architecture is very common, and Digital Ocean is becoming increasingly popular. A concrete solution here would be much appreciated by many.

• rdisk value in boot.ini maps to which disk?

  - by MA1

  Hi All Following are the contents of a sample boot.ini: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /NOEXECUTE=OPTIN /FASTDETECT multi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows 2000 Professional" /fastdetect multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /NOEXECUTE=OPTIN /FASTDETECT rdisk value tells the physical disk number. so, if i have three hard disks say: /dev/sda /dev/sdb /dev/sdc than how to know which disk(/dev/sda or /dev/sdb or /dev/sdc) is rdisk(0) and which disk is rdisk(1) etc Regards,

• question about IP address

  - by baddogai

  i know how IP basically works, and knows that an IP address composed of a network ID portion and a host ID portion, but when I type a IP address ,say "8.8.8.8" into the web browser, i DIDN'T supply any subnet mask information, so how does the browser know where the dividing line is between the network ID and host ID? since 8.8.8.8 may mean 8.8.8.8/8, 8.8.8.8/24 etc. In a nutshell, the IP address I supplied is ambiguous.

• What's the reason to break HDD to few partitions for MDADM+LVM2?

  - by archer

  I'm using 2 HDDs each 1TB in size. I'm going to create MDADM+LVM2 over them. Initially I though about this partition layout: /dev/sda1 - 1Gb (boot) /dev/sda2 - 500Gb (md0) /dev/sda3 - 499Gb (md1) /dev/sdb1 - 1Gb (boot) /dev/sdb2 - 500Gb (md0) /dev/sdb3 - 499Gb (md1) md0 is going to be raid0 and md1 is going to be raid1 however, I found some info that this would be better to break each drive to more partitions (lets say 10 partitions 100Gb in size each). What's the reason of doing that?
