  • Why is apache/passenger unable to open the sqlite3 rails database file?

    - by sendos
    I'm running apache2/passenger2.0.3 (ubuntu 9.10 packages). I can start up Webrick in the rails folder and run the app perfectly as I do on my development box with script/server Why then does apache/passenger fail to open the database, throwing a 500 and putting the following in the log? Status: 500 Internal Server Error could not open database: unable to open database file /usr/lib/ruby/1.8/sqlite3/errors.rb:62:in `check'...

  • Need a simple program to convert to utf-8

    - by Null
    I need to find a program to convert a Windows-1250 encoded file to utf8. It needs to be a standalone program (not a python script) and it needs to run on windows (without install). If I can make the conversion using the commandline that would be perfect. Yes I know notepad can do that but this is meant to be automated.

  • Setting udev rules in Linux Mint 13

    - by user1233963
    What I'm trying to do is set up a udev rule for my HP headphones (usb) with the aid of several tutorials out there. Created a file ( 90-local.rules ) in /etc/udev/rules.d and added the following: ACTION="add",SUBSYSTEM="usb", ATTR{vendor}=="Hewlett-Packard", RUN+="sh /home/alex/Scripts/usb.sh" The problem is nothing happens when I connect the headphones! What am I doing wrong? note: I did restart udev and the script works also, so it's not that

  • Photocopying using a separate scanner and printer

    - by jay
    I have 2 printers. HP Deskjet F2235 - designated scanner (has printing issues) Brother HL-2040 - designated printer (doesn't have a scanner) Just by using those two both connected to the same computer, is there a way to perform a photocopy operation by scanning via the designated scanner then immediately it being printed from the designated printer? Obviously you could save the scanned files then print them, but short of making a script or manually doing this, is there a faster automatic way through settings or third-party software?

  • Sending mail from command line if body not empty

    - by cdecker
    I'd like to write a simple script that alerts me if a log changes. For this I'm using grep to find the lines I'm interested in. Right now it works like this: grep line /var/log/file | mail -s Log [email protected] Problem is that this sends a mail even if no matching lines are found. The mail utility from mailutils seems to have no switch telling it to drop mails that have an empty body. Is there a quick and easy way to do so?

  • How to change the default terminal emulator on Windows (cmd)?

    - by alex
    Is it possible to change the default terminal emulator on Windows (7 and 8 in particular) from cmd to, for example, Console2 or ConEmu? In essence, I want all command line tools, whether launched by double clicking, from "Run" or by other processes to use the custom terminal. This is a trivial matter on Linux, is it even possible on Windows? It would be especially helpful if this could be done via a script.

  • Grab latest version of PHP by URL? [closed]

    - by luckytaxi
    I'm unable to find the directory listing of all PHP packages. I'm basically looking for the latest stable version of 5.3 utilizing some sort of script that will go out and check PHP's website. If I can get a directory listing (can't seem to find one), I can do the rest. Figured it out but seeing that someone else posted something similar but for Apache, he got blasted for puttig it on Stackoverflow. I figure I would save myself the trouble and post it here.

  • What IT tasks have you found in your career to be just painful

    - by Chopper3
    We always try to be clever and script everything that we find repetitive but not everything can be automated - what have you found in your career to be just a massive pain? I'll give you mine - building Netware version 2.xx on 5.25" disks with multiple NICs - this often took HOURS of swapping disks, pacing around, swapping disks, more pacing etc. Then finally it would hopefully work - if you'd not set the IRQs/DMAs right you had to start again, wow I loved version 3 which didn't need all that. What about you?

  • Linux: permission to read file from /sys/kernel/debug wihout root privileges

    - by gogowitczak
    I'd like to read small text file, located at: /sys/kernel/debug/vgaswitcheroo/switch without root permissions. It contains information about graphic cards (dedicated ATI Radeon and integrated Intel HD3000). I wrote a simple script displaying infomation I need, but it works only with root privileges. I already tried changing file & folder permissions, but when I restart my computer, the problem remains. Is it possible to permanently change that file permissions or owner?

  • Freebsd ports installing with parameters

I've tried almost everything but no success. I.E: I'm trying to install nginx with HTTP_SSL module but i can't seem to pass the correct parameter to the make install clean command. I also want to use all other default settings, and only change this one. Any help will be appreciated.

  • Architectural advice - web camera remote access

    - by Alan Hollis
    I'm looking for architectural advice. I have a client who I've built a website for which essentially allows users to view their web cameras remotely. The current flow of data is as follows: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Ftp connection is enabled for the cameras ftp user. Web camera opens ftp connection to server. Web camera begins taking photos. Web camera sends photo to ftp server. On image url request: Server reads latest image on hard drive uploaded via ftp for camera. Server deleted any older images from the server. This is working okay at the moment for a small amount of users/cameras ( about 10 users and around the same amount of cameras), but we're starting to worrying about the scalability of this approach. My original plan was instead of having the files read from the server, the web server would open up an ftp connection to the web server and read the latest images directly from there meaning we should have been able to scale horizontally fairly easily. But ftp connection establishment times were too slow ( mainly due to the fact that PHP out of the ox is unable to persist ftp connections ) and so we abandoned this approach and went straight for reading from the hard drive. The firmware provider for the cameras state they're able to build a http client which instead of using ftp to upload the image could post the image to a web server. This seems plausible enough to me, but I'm looking for some architectural advice. My current thought is a simple Nginx/PHP/Redis stack. Web camera issues post requests of latest image to Nginx/PHP and the latest image for that camera is stored in Redis. The clients can then pull the latest image from Redis which should be extremely quick as the images will always be stored in memory. The data flow would then become: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Camera is sent an http request to start posting images to a provided url Web camera begins taking photos. Web camera sends post requests to server as fast as it can On image url request: Server reads latest image from redis Server tells redis to delete later image My questions are: Are there any greater overheads of transferring images via HTTP instead of FTP? Is there a simple way to calculate how many potential cameras we could have streaming at once? Is there any way to prevent potentially DOS'ing our own servers due to web camera requests? Is Redis a good solution to this problem? Should I abandon PHP/Ngix combination and go for something else? Is this proposed solution actually any good? Will adding HTTPs to the mix cause posting the image to become too slow? Thanks in advance Alan

  • Lighttpd Prepending Strings to Certain Files.

    - by Kyle
    I have a Mint install (Fantastic stats, if you were wondering) and I would like to move over to Lighttpd for my server needs. Unfortunatly, this means that php_auto_prepend is no longer easily available. I understand that PHP can do this in the php.ini file, but I have areas that can't have this value prepended so that's out of the question. Is there a lighttpd way to prepend my script for my mint install in some files, and have it disabled for others?

  • How can I run a PowerShell function remotely?

    - by Aimar
    Using powershell, I plan to run many functions on a remote host to gather information. Here is an example to retrieve the content of file remotely just by running a function called getcontentfile with the parameter as the name of the remote host: function getcontentfile { [CmdletBinding()] param($hostname) $info = Get-Content "C:\fileinfo.xml" write-host $info } This function should return information about the remote host to the local instance of PowerShell. How can I modify this script to do that?

    - by NoCarrier
    I frequently come in contact with people who absolutely cannot operate a PC, no matter how you train them. I need some sort of programmable physical button or remote control, where when they click it, it will execute a script on a windows machine. (and no, wiseguys, a mouse won't do) Does such a thing exist?
