• .bat file to update loopback controller to external ip

  - by cable729

  Okay, so I've figured out how to get my external ip using wget: wget -q -O - http://whatismyip.com/automation/n09230945.asp that outputs the ip to the command console. adding currentip.txt to the end will write it to a text file. But what I want to do is use netsh interface ip set address name="Local Area Connection 2" source=static addr=[WHAT DO I PUT HERE] Also, a way to make the command prompt not flash would be nice too :)

• How to create launch icons on Ubuntu Desktop?

  - by MattSlay

  I installed Ubuntu in a VM using VirtualBox, and after a few hours of Googling all the things I had to install and configure for the rest of the environment, I am finally up and running with a Ruby on Rails IDE and have MySql up and running. After I start up the Ubuntu VM, I have to go to a terminal window and do this to start MySql: /etc/init.d/mysql start So that works fine, but, since I am such a GUI person, I’m wondering how I can create an icon on the Ubuntu Desktop that I can click on to launch this command. Can you tell me how to do that?

• Move /var directories to to /mnt on an EC2 instance

  - by Geoff Lanotte

  I am trying to work on a standard configuration for a set of EC2 instances running ubuntu 12.04. These servers are going to be primarily web servers for a Ruby on Rails application. When you configure a new large instance, you are given a primary of 8GB and then ephemeral storage of 400 GB that is mounted to /mnt. It seems logical to me to move some directories that have a potential for growth off to the /mnt directory, I was specifically thinking of /var/www and /var/log. My question is two-fold: Is this a good idea or are there pitfalls that I cannot see? If this is a good idea, how should I go about configuring this. I do have the ability to configure new instances and down our old instances. My concern is over long term, doing this in such a way that it prevents downtime. I am a developer with some experience in devops, but mounting drives is something I have not faced before, so explicit directions would be greatly appreciated.

  - by zzapper

  (Sorry I know this is an old chestnut; I have found similar answers here but not an exact answer) These are frequent hand written queries from a console so I is what I am looking for is the easiest thing to type SELECT * FROM tbl_loyalty_card WHERE CUSTOMER_ID REGEXP "[0-9A-Z]"; or SELECT * FROM tbl_loyalty_card WHERE LENGTH(CUSTOMER_ID) >0; -- could match spaces Do you have anything quicker to type even if it's QAD?

• General purpose ticketing/tech support system [closed]

  - by crazybyte

  Possible Duplicate: What’s your favorite ticketing system? I was wondering if somebody could recommend me a very user friendly or simple general purpose ticketing/tech support system. I need something that is web based, preferably open-sourced/free software implemented using PHP, Ruby, Ruby on Rails or Java (as back end) with MySQL or PostgreSQL as database engine. I need something that is not development management oriented or project management oriented like Eventum or similar (random example), something to which the user can connect open a tech support request and be able to follow it until is solved or dropped.I need it to be open-sourced to be able to modify it if there is a need or extend it. I tried a number of such systems available and I found that osTicket or eTicket is something that it's close to what I need, but the code is somewhat flaky and some of the features are working badly or behaving strangely. Any thoughts/advice where to find something similar? Thanks!

• What's the easy way to test for 304 reponses?

  - by John Mee

  I need to test if my 304 responses are working, but my development environment is pretty hard set on force no-cache. Is there an easy way to modify the max-age value of the cache-control header before it goes out? I'm perhaps a bit optimistic in hoping chrome (or an extension, or FF) has a console command letting me alter the if-modified-since header then send the request. Maybe paste something into a telnet connection?

• How can I make Emacs start-up faster?

  - by Colin

  I use Emacs v. 22 (the console version, either remotely with PuTTY or locally with Konsole) as my primary text editor on Linux. It takes a while to load up each time I start it though, probably almost a second, although I never timed it. I tend to open and close Emacs a lot, because I'm more comfortable using the Bash command-line for file/directory manipulation and compiling. How can I speed up the start-up time?

• Preconfigure Android Emulator with location?

  - by Janusz

  I want to run automated tests with location on the android emulator. I can setup coordinates via Telnet, but that means starting up a console and manually configuring the emulator before running my junit tests. Is there a possibility to preconfigure the emulator with a KML file or something like that to ensure that there are always coordinates available?
