The find utility on linux allows you to pass in a bunch of interesting arguments, including one to execute another command on each file. We’ll use this in order to figure out what files are older than a certain number of days, and then use the rm command to delete them.

Example: 

find /path/to/files* -mtime +5 -exec rm {} \;

Add the line

default-character-set=utf8        

to [mysql] sections of my.cnf (/etc/my.cnf on some systems , /etc/mysql/my.cnf  on Ubuntu, use find or locate to find out).

You may wish to add the line to [client] section instead to make all clients use UTF-8 encoding for all connections.

The RSS url:

http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=<User Name on Twitter>

 Suppose, you’d like to subscribe to twitter feed for a fictitious twitter user known as random_j_user using some RSS aggregator such as Google Reader.

Add the following url to your aggregactor of choice

http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=random_j_user

For more options see the official documentation.

To install NVIDIA closed source driver, open-source nouveau drivers should be disabled.

Older post shows how nouveau drivers could be blacklisted on some popular distros. That recipe is not enough for CentOS 6.x.

You should also edit /etc/grub.conf and reboot.

Just add rdblacklist=nouveau to the end of line with kernel directive in grub.conf file.

To compile/link Qt programs with KDE 4 libraries using qmake build system:

1. Install the kde lib development package:
   

   sudo apt-get install kdelibs5-dev

2. Specify kde user interface libraries in .pro file:

   LIBS     += -lkdeui

I had garbled output in console when installing ubuntu server amd64 on computer with Nvidia Quadro 2000. I was able to log-in, but all output was completely unreadable.

As it turned out, the problem was in nouveau video driver, which is incompatible with some nvidia cards. I was able to login in recovery mode; other choices are boot some other linux form CD or USB or login via ssh from some other computer.

After getting access to filesystem, you should disable nouveau driver by adding

new file with .conf extension to /etc/modprobe.d

/etc/modprobe.d/disable-nouveau.conf:

blacklist nouveau
options nouveau modeset=0

curl --write-out %{http_code} --silent --output /dev/null URL

• HTTPie is a better curl

This recipe may also apply to CUDA 4.0 and 4.2. 

When you install VS Express edition alongside with Windows SDK 7.1 you can create 64-bit binaries. With properly installed CUDA SDK, 64-bit cuda code could also be built. Except for one thing: you may not clean or rebuild projects with files compiled by nvcc. You are able only to build those projects.

If you get an error similar to

<…>\CUDA 4.1.targets(445,9): error MSB3721: The command <…>  exited with code -1.

If you have problems with slow response from (some) ssh hosts, try editing

/etc/ssh/ssh_config

on your client box and set

GSSAPIAuthentication no

This may help. Alternatively, you may put this line in your ~/.ssh/config

Use pwdx <PID> , e.g.:

find . -type f -exec dos2unix {} +

Using utilitites from WinSDK

dumpbin /headers some.exe | findstr "machine"

You get output like:

8664 machine (x64)

or:

14C machine (x86)
