As ‘man convert’ states :
The convert program is a member of the ImageMagick suite of tools. Use it to convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more.
I tried to resync a slave MySQL after it disconnected from the master. But the binary log was already deleted on master, so the only solution was to restore from the last backup. To avoid lock tables on the master and remember the binary log name and position to put them on the slave configuration, there is a tip to take care of all that : the “–master-data” option in mysqldump.

To import a local CSV file into MySQL, use the syntax below :
LOAD DATA LOW_PRIORITY LOCAL INFILE '/path/tofile.csv' INTO TABLE database.table FIELDS TERMINATED BY ';' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '"' LINES TERMINATED BY '\n' IGNORE 1 LINES (`field1`,`field2`,...)
By default, in Cheyenne, the header size limit for a post request is 102’400.
If you want to ajust this limit you can define the post-mem-limit parameter in the global context or in a specific webapp.
For example, to double the initial limit in the httpd.cfg, :
... default [ root-dir %./www/ default [%index.html %index.rsp] post-mem-limit 408'800 ] ...
