ads' corner

Up until recently I was using an App to clean the the Android cache once in a while. If you don't, the device over time get's sluggish, because too many apps store too much data in the cache. Over time this cache can grow to GBs in size.

On the other hand, every single "clean cache App", over time, started showing more and more aggresive advertising. I get that the developer wants to make some money, that's fine. But maybe the money is not enough, so more advertising it is.

Turns out, there is a built-in way in Android to clean the cache. No need for an extra App.

Recently it was time to refurbish our email infrastructure. For a very long time I was hosting everything for myself, but things don't get easier and over time even the spam filters couldn't catch up. Therefore I looked into a number of hosted services, and in the end settled with Google Gmail.

Recently smplayer (not mplayer) started behaving strange: every video started muted. Pressing the mute button (m key) really muted the sound, pressing the button again unmuted the sound and the audio started playing. This behavior persisted over restarts of smplayer.

Now that is really annoying!

I'm a (more or less) happy KDE user, ever since the KDE 3 days. Before that, I used fvwm2 for a long time, but that is a different story. It also happens that I never really reinstalled my home directory - the oldest files I can find are from 1997, and that is pretty much when I switched from an old Slackware system with self-compiled updates, to something with a more modern distribution. That means, that all the time from 1997 to today, I carry the same /home/ads across my computers. The home directory grew from a few MB to 133 GB today (maybe I should clean it up, but then again it's cheaper to buy a bigger harddisk).

It also means, that I never deleted my KDE config, even when upgrading to KDE 4 or Plasma.

For quite a while now, my wife and I were using Trello to keep things organized. We both had our private lists and boards, and also a few shared boards for joint tasks. Over time we realized that this tool is more annoying than helpful, and we decided to try something else. After a lengthy discovery phase we settled with Wunderlist.

There are a few requirements we have for a to-do list tool:

• Shared boards/lists
• Managed using a Website, obviously
• Android app, possibly iOS app
• Proper notifications, as in configurable alarms and separate notification per task
• Subtasks and checklists
• Attachments
• Option to assign a task to someone else
• A bit more fancy and modern interface than Trello has

All in all not very advanced features, all basic stuff.

Google Summer of Code 2011 is in the second term. Leonardo Sápiras passed the midterm evaluation and continues his work on the phpPgAdmin plugin infrastructure.

His work is already in an advanced stage, time to take a look and show you, what's possible.

It is possible to generate random numbers in a TeX document. For a gimmick i wanted a random line from a text file in my slides. The first step was to find a random number.
