Perl script to convert standard input to ascii values, useful with web code.
You can take the output and insert directly into HTML pages.
#!/usr/bin/perl while(sysread(STDIN,$a,1)) { $c=ord($a);if($c==10) { print "n"; } else { print "&#$c;"; } } exit(0); __END__ [/solution]

You want to switch user from the MS DOS prompt.
[/problem]
[solution]
Use runas
runas /?
[/solution]
[example]
Switch user to other id (Then just run explorer and browse to directory)
runas /user:USERID@xxx c:\winnt\system32\cmd.exe
Where user-id is the USER you wish to change to. For example Admin. xxx represents the hostname of the box or domain.
You can also just use local, if changing to user on the same box, like this:
C\:Documents and Settings\Admin runas /user:localmarcus "c:\WINDOWS\system32\cmd.exe" Enter the password for localmarcus: Attempting to start c\:WINDOWS\system32\cmd.exe as user "localmarcus" ...

You want to create an image text label.
[/problem]
[solution]
Use GD library that can be built-in to PHP. Or just use my free on-line tool to create it, as shown in example below.
Once GD is built in – use this PHP code to generate the label.
[/solution]
[example]
This shows the label .
You can use this to generate black blank images, with white superimposed text over the top:
.. click this link, change text “label” – then save to your machine.

[problem]
You want to back up your mysql database.
[/problem]
[solution]
This script is good for backups, as it will generate a dump – zipped and as the day of the week is used (in the backup file name), automatically rolls every 7 days.
Run it daily or every other day. If you want a months worth, guess can just change the date command, etc.
[/solution]
[example]
#!/bin/zsh [ $# -ne 1 ] && { echo "Usage: $0 db" exit 1 } db=$1 dbd="/PATH_TO_YOUR_BUS/$db.$(/bin/date +%a)" # set the path alias mysqldump="/usr/bin/mysqldump" # you may need to modify this alias gzip="/bin/gzip" # may need to change this too # set your password and user mysqldump --user=root --password=your_password $db > $dbd gzip --best --force $dbd exit 0 [/example]
