within specifications —as one blog wasn’t enough

Posted on Mar 23, 2014

This post is more of a status update. I recently started a new, technical blog. The name is within specifications and you may check it out at withinspecifications.30ohm.com. I won’t abandon this blog, which anyway I update at a less than slow rate. The new blog’s focus will mainly be ECE stuff.

Android, Open Source and a self-induced hackathon

Android, Open Source and a self-induced hackathon

tl;dr Android as a whole -from Google’s code repository to cheap Chinese tablets- is open source to a certain extent but, although this acts as a cushion for poor product releases, it isn’t an excuse. Some weeks ago I had to spend more time than usual to get my Android devices do my binding; more time as in four (4) days! When it comes to Android, I am an advanced user, having rooted and flashed some ROMs on my devices. Also, due to my Linux knowledge, Android’s lower levels don’t feel that strange to me. That said, without any specific knowledge, in 4 days I got to resolve a hardware (software related though) issue, write a really basic Android...

Gitlab 4.0 on a Gentoo server, ~amd64, hardened w/ Apache.

Gitlab 4.0 on a Gentoo server, ~amd64, hardened w/ Apache.

The article about Gitlab on Ubuntu gets some views every day, so I guess it is an interesting subject -and it should be. GitLab is a great project. It could do with less RAM consumption and less frequent updates though, but I am only whining because I am using it and I am not going to uninstall it anytime soon. :p The thing is I am in love with Gentoo for many years now and my Ubuntu server was more like an one time thing. So I set to install Gitlab on my ~amd64 hardened Gentoo and log the process for anyone interested. It is a great time too since Gitlab recently reached version 4.0 with enhanced project management.   Update (9 July 2013): An excellent article for...

GitLab on an Ubuntu 10.04 server with Apache

GitLab on an Ubuntu 10.04 server with Apache

Recently I saw the light, or something very bright at least, and decided it is time to use a central git repository to store my personal projects which span across many categories (code, documentation, translations, scripts, etc). Alas, as it usually is the case when you decide to change your workflow, you have to give it a bit more thought. The thing about personal projects, is that there are too many of them and none has a known or at least certain development timeline. I may work on my backup script (mrbStudio) today and touch it again after two years, when I’ll need a new feature. Thus, the need for project management: documentation, issues, code snippets, etc....

Yet Another Backup Script: mrbStudio

Yet Another Backup Script: mrbStudio

Some years ago I decided that I needed backups. Our systems are more fragile than we tend to think; hardware break downs, hard disks failures, laptop thefts, accidents, software malfunctions or user errors can strip us of our precious data. By data I mean both things we can’t afford to lose (like your work files or photographs) or things it would take a great amount of time to replace (like your OS installation along with a ton of custom settings). I tried to think of a backup policy that would work for me, an advanced user. I knew I wanted something that would be easy to access, like a copy of an original directory and maybe versions, so I can return my files to a...

Wallpaper: KDE – permanent type

This is the fourth and last wallpaper of the KDE wallpapers week. It is the less “clean” image in this series. I think that it doesn’t match up well with widgets but if you have a virtual desktop clean of plasmoids you will love it. It is so good it may even get you a girlfriend! :p for 4:3 monitors KDE - permanent type - 1600x1200 for 5:4 monitors KDE - permanent type - 1280x1024 for 16:10 monitors KDE - permanent type - 1280x800 KDE - permanent type - 1680x1050 KDE - permanent type - 1920x1200 for 16:9 monitors KDE - permanent type - 1920x1080 KDE – permanent type...

Wallpaper: powered by KDE

Yesterday I decided to play a bit with textures and the result was a KDE wallpaper! I love it and I hope you will like it too! I will post a plain version without the colored straws soon. For the photography savvy this photo was captured with my Canon EOS 500D and the EF 50mm f/1.8 (no mkII version here). You can download it below at various resolutions. Each ratio comes from a different crop area of the original, so download the appropriate ratio for your monitor  since you can’t get for example the 16:10 image if you crop the large 4:3 image. If you like it , you can give it a vote over kde-look. ...

New theme, new 404 page, new server and zero ads!

New theme, new 404 page, new server and zero ads!

Quite some changes happened at the website in the last few hours and I want to write some lines about it.   new theme As you can see I installed a new theme. I have fallen in love with it from the first moment I saw it. It is simple and elegant, perfect for a personal site. It may be a bit disorienting  that the first post you see on the home page isn’t the most recent post in general but the most recent post in the featured articles category, but I prefer it that way. This change wasn’t easy though. I had to make the theme xLanguage (multilingual) compatible, to fix an issue with international characters, to add some rss icons (borrowed from Atahualpa)...
