Android Developer site gives instructions on how to connect to a phone from Ubuntu, but no instructions are given for Fedora. These are the steps I followed to connect adb to a Samsung phone on Fedora 14:
As root, create a file named /etc/udev/rules.d/51-android.rules with following contents (04e8 is Samsung vendor id):
SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0...
As root, run udevadm control --reload-rules
Unlug the phone if clready connected.
Connect to phone with adb (kill server if already started):
$ ./adb kill-server
$ ./adb devices
* daemon...

The Java keytool utility does not support importing a private key directly from a file. But it does support merging a keystore with the -importkeystore command. So, for a private key generated with OpenSSL in PEM format, you first convert the PEM key into PKCS12 format , then merge the one-key PKCS12 store with the Java KeyStore:
C:\>keytool -importkeystore -srckeystore openssl_c...

I have long noticed that IE8 displays a "broken page" icon while showing my web pages, but didn't pay much attention. Since the world in general considers IE to be broken, it's not so unlogical for IE to see much of the world as broken. Until one day I noticed that the Google home page was not "broken". Then I thought may be I should fix my pages also. So I moused over the "broken page" icon, and this is what I saw: Compatibility View: websites designed for older browsers will often look better, and problems such as out-of-place menus, images, or text will be corrected. Very descriptive indeed! Older browsers? Such as Firefox 1.5? When it comes to MS products, I often had better...

If Command Extensions are enabled (which is enabled by default), then there are several dynamic environment variables that can be expanded but which don't show up in the list of variables displayed by SET . These variable values are computed dynamically each time the value of the variable is expanded (but see example below). If the user explicitly defines a variable with one of these names, then that definition will override the dynamic one described below: %CD% - expands to the current directory string. %DATE% - expands to current date using same format as DATE command. %TIME% - expands to current time using same format as TIME command. %RANDOM% - expands to a random decimal number between 0 and 32767. %ERRORLEVEL% - expands to the...

By the perldoc ,
use Module LIST;
is exactly equivalent to:
BEGIN { require Module; Module->import( LIST); }
Because of the BEGIN block, use is executed immediately. Therefore, it is not suitable for lazy loading of modules at runtime.
use does not work with a runtime variable:
C:\>perl
$cgi = "CGI";
require $cgi;

require works:
C:\>perl
$cgi = 'CGI';
require "${cgi}.pm";

Also, file extension is required if require is not passed a bareword:
// this works
require CGI;

Read a directory and sort files by modified date (oldest to newest):
$dirname = ".";
opendir(DIR, $dirname) or die $...
Same, but with glob (note that the output is a bit different):
$dirname = ".";
@files = sort { -M $b <=> -M $...
Switch the places of $a and $b to order from newest to oldest.
