2-cent Tip: Checking remote hosts for changes

On occasion, I need to check my clients' sites for changes against the backups/mirrors of their content on my machine. For those times, I have a magic "rsync" incantation:
rsync -irn --size-only remote_host: /local/mirror/directory|grep '+'
The above itemizes the changes while performing a recursive check but not copying any files. It also ignores timestamps and compares only file sizes. Since "rsync" denotes changes with a '+' mark, filtering out everything else only shows the files that have changed in size - which includes files that aren't present in your local copy.
This can be very useful in identifying break-ins, for example.

2 cent tip: reading Freelang dictionaries

Freelang has a lot of (usually small) dictionaries, for Windows. They have quite a few languages that aren't easy to find dictionaries for, so though the coverage and quality are usually quite low, they're sometimes all that's there.
So, an example: http://www.freelang.net/dictionary/albanian.php
Leads to a file, dic_albanian.exe
This runs quite well in Wine (I haven't found any other way of extracting the contents). On my system, the 'C:\users\jim\Local Settings\Application Data\Freelang Dictionary' translates to '~/.wine/drive_c/users/jim/Local\ Settings/Application\ Data/Freelang\ Dictionary/'. The dictionary files are inside the 'language' directory.
Saving this as wb2dict.c:
#include <stdlib.h>
#include <stdio.h>
int main (int argc, char** argv)
{
char src[31];
char trg[53];
FILE* f=fopen(argv[1], "r");
if (f==NULL) {
fprintf (stderr, "Error reading file: %s\n", argv[1]);
exit(1);
}
while (!feof(f)) {
fread(&src, sizeof(char), 31, f);
fread(&trg, sizeof(char), 53, f);
printf ("%s\n %s\n\n", src, trg);
}
fclose(f);
exit(0);
}
The next step depends on the contents... Albanian on Windows uses Codepage 1250, so in this case:
./wb2dict Albanian_English.wb|recode 'windows1250..utf8' |dictfmt -f
--utf8 albanian-english
dictzip albanian-english.dict
(as root
cp albanian-english.* /usr/share/dictd/
add these lines to /var/lib/dictd/db.list : database albanian-english { data /usr/share/dictd/albanian-english.dict.dz index /usr/share/dictd/albanian-english.index }
/etc/init.d/dictd restart
and now it's available: dict agim 1 definition found
From unknown [albanian-english]:

2-cent Tip: A better screen, byobu

The screen command with pre-set status bar, and cool (easy to remember) shortcuts, like F3, F4, F5 and a configurable menu on the F9 button.
yum install byobu
Got a nice screenshot at: http://www.mind-download.com/2010/09/better-screen-byobu.html
