What if you could replace the button provided by Facebook with a single and simple image of the same button showing up-to-date number of followers of your Facebook page? It would be fantastic for website performance optimization or WPO, because it would only require a single additional request to the server, and it could be served and cached quickly from a CDN very close to the user’s geographic location. In this way you could ensure that the loading speed of your website would remain very high and without performance penalties.
How can this be achieved? It seems a win-win solution too good to be true… Well, it can be achieved in a much simpler way than you think thanks to the Imagemagick library and a simple Bash script. Read on…

One of the most common and tedious tasks of a sysadmin is to prevent file systems become completely full, because when a server runs out of space the consequences are unpredictable.

Not only modifies appreciably the number of visits per se, but also the number of page views per visit, bounce rate and average time spent per user among many other parameters. This makes sense, as it is when we spend more time reviewing each and every one of our web pages or performing unfinished development tasks.

Those who use the tool KeePassX (KeePass clone for Linux and Mac OS X) to safely save passwords and login details at one single place will have seen many times on the need for rapid access to their repository of passwords with a single click. However, by default when accessing KeePassX none repository is open, or one is open that does not correspond to the one we want to check, so often it’s necessary to browse the file system to locate and select the corresponding file. If in addition to a master password we use a key file to improve security, we have to repeat the same process over and over again to locate and select the key file.
