Plastic bottle PET filament extrusion for 3d printer: experiments

This will not be a guide to build your own filament extruder, there’s already a very good guide by Ian McMill on instructables, which incidentally I followed to build my own version. This is a report of my own experience with trying to obtain 3d-printer-worth filament out of plastic PET bottles. I was enthusiastic of […]

Dominant color of image as background of DIV, all in CSS

I was trying to do something fancy, and have a grayscale image turned into colored mode on mouse hover, together with showing a popup… and I obviously wanted the popup background color to be related to the image that had just been coloured up. There is a precise javascript function that does that, it’s the […]

403 Permission denied on Apache in Debian/Ubuntu with changed document root

I had just made a brand new installation of both Ubuntu trusty and vivid and Debian jessie (tried all of them) on my android phone with Linux Deplow, and installed the LAMP stack via SSH. I wanted Apache to serve files decrypted from an EncFS mount, so I found easier to move the DocumentRoot to […]

This was tested and works in my configuration using a Sound Blaster USB Surround Pro X-Fi, and doesn’t involve any patch or […]

Change the user Transmission Debian daemon runs under and avoid warning message

I am writing this post also for personal reference (and currently I am writing in bare HTML since my WordPress installation lacks an updated multilanguage plugin to be able to use the WYSIWYG editor). I was moving my home server from a slow Raspberry PI to a way faster Cubieboard 2, and got to reinstall […]

Cyclic sound MP3 audio recording in ubuntu

I work in a relatively safe environment, yet it may very well happen that I need to prove something that someone said in my office, so I can hold it against them when the time comes. My laptop is always turned on, so I could use it to record the environmental sounds around it, with […]
