Speed Up Cydia – Remove Cydia ads

SSH into your iDevice and browse to /Applications/Cydia/ and create two copies of package.js computer ( one is your backup and you will edit the other one ) .
Inside that file search for
var depiction = package.depiction
. Edit that line so that
depiction = package.depiction
will become
depiction = null
Now save the file and copy it back to /Applications/Cydia/ , overwriting the original one. Thats it. Now restart Cydia and enjoy.

Compress MysqlDump Output

      Making backup

all databases

    :

mysqldump -u root -p --all-databases > dump.sql

      Making backup only

one database

    :

mysqldump -u root -p --databases db1 > dump.sql

      Making backup

many databases

    :

mysqldump -u root -p --databases db1 db2 db... > dump.sql

      Making backup with

triggers

    :

mysqldump -u root -p --triggers --all-databases > dump.sql

    Making backup with

procedures and functions:

mysqldump -u root -p --routines --all-databases > dump.sql

    Now let’s compress our dump in real time with

gzip:

mysqldump -u root -p --all-databases | gzip > dump.sql.gz

    We can still reach a higher compression ratio using the

bzip2:

mysqldump -u root -p --all-databases | bzip2 > dump.sql.bz2

Making a comparison between the dump with three compression options (none, gzip and bzip2) had the following result:

    Dump normal – 947k
    Dump com gzip – 297k
    Dump com bzip2 – 205k

And how do I restore the dump?

Normal:

mysql -u root -p < dump.sql

gzip:

gunzip < dump.sql.gz | mysql -u root -p

bzip2:

bunzip2 < dump.sql.bz2 | mysql -u root -p
