Code:

$ a=lilolal ; echo ${a/lal/uuu}
lilouuu

To move files "copied" on clipboard (Konqueror/perhaps dolphin) to the place you're on a terminal, without navigating/browsing the folders on the file manager, one can use:

xsel -b | while read f ; do mv -i "${f#*file://}" ./ ; done

As "copied" files on Konqueror are registered on the clipboard as a list with "file://" preceding the path. Perhaps could be aliased...

Pyplate now uses WSGI instead of CGI

Posted 07-10-2014 at 01:09 AM by Pyplate

Tags pyplate, python, wsgi

I've updated Pyplate again. This time the UI hasn't changed much, but I've done a lot of work under the hood. I've added a bunch of fixes which should make Pyplate much more secure.

I've also switched moved away from CGI amd updated Pyplate to use WSGI. This has made a huge difference to the page load time of dynamic pages. Performance with static pages hasn't really changed.

There's now a simple web server supplied with Pyplate. It's a little slower than Nginx...

Runit or s6...

Posted 07-08-2014 at 11:33 PM by ReaperX7

To date, I've been working with Runit to introduce a new type of init system to GNU/Linux. In retrospect Runit has worked wonderfully minus some tedious bugs with partition dismounts.

Runit has worked wonderfully as an init and I can only hope that it keeps getting better than better. It's stable and is very unintrusive.

All it needs are a mountain of service scripts to fuel it and with a symlink to the proper directory, off it goes.

KDE, QT, GTK, TK, all in several versions and with changing variables and whatnot at every version, and even within a single version.

One would think that QT and KDE are more or less the same, but turns out that, at least from outside KDE, one can't fully define the theme settings (or UI font specifically) from KDE's "appearance" settings. Even for apps that aren't "standalone QT", but KDE! Like fonts on konqueror, and probably dolphin too. KDE has a longstanding...
