revnode / push a string in a command's stdin
Created June 5, 2013 19:02
Using a bash "here strings" and "here documents" look leeter than piping echo into the command. Also prevents subshell execution. Word is also expanded as usual.
command <<< word

revnode / tar.gz with gpg-encryption on the fly
Created June 5, 2013 17:46

tar -cvz /<path>/ | gpg --encrypt --recipient <keyID> > /<backup-path>/backup_`date +%d_%m_%Y`.tar.gz.gpg

revnode / Regular Expressions
Created May 26, 2013 18:23
I know you'll fall in love with this feature, no more js or a server side code to check if the user's input is a valid email or url adress, with the pattern attribute you can use regular expressions directly.
<input type="email" pattern="[^ @]*@[^ @]*" value="">

revnode / Download Attribute
Created May 26, 2013 18:22
The HTML5 download attribute allows developers to force a file to download rather than go to that specific page, you no longer need to rely on server side code to do that.
<a href="download_pdf.php?id=15" download="myfile.pdf">Download PDF</a>

revnode / Link Prerendering
Created May 26, 2013 18:21
Also you can use the prerendering feature which will make your website even faster, the browser will fetch and render the entire next page on the background and show it only when the user click on the link.
