Offline FreeDB – Example

It’s been quite a while since I released Offline FreeDB. In the meantime I’ve been too busy to go more into detail. Here at last I’ll show to you how to implement the fast Offline FreeDB Java library to query the FreeDB database and find information for almost any disc or bundle of music files you’re looking for.

Zarafa packages for Arch Linux ARM / x86 / i686

Lately someone asked me for help with his Zarafa-Server on his RaspberryPi 2 (ARM). He tried to build an installation package with my MAKEPKG file from Archlinux User Repository. But shortly I realized that it’s a pain compiling with gcc 5 on his system.

So that nobody else has to go through this, I decided to create a package repository for Arch Linux ARM. There you’ll find the latest build of Zarafas installation packages for Odroid and Raspberry Pi 2 devices.

Since I’m using this packages on my own, I can tell it’s working by the day it’s created. Future versions will be released as soon I proved them working integrated with the other Zarafa related packages.

Zarafa Mailserver

It’s hard to explain how much work it is to setup your own private state of the art private mail service. The list of components to care of might be pretty scary. But from my own expirience I can tell, it’s possible!

That’s why I decided to write some tutorial about this and share my knowledge. My final objective is to show how you can setup and run a mailserver keeping your mails at home and letting a smarthost handle transfers and checks.

How to recognize music content?

Having a glimpse at my media made me realize it’s hard to distinguish anything. Some files are poorly named and have no tags inside. Some files were named after their track title but without track numbers. Seems like I should have done a better job organizing my music 🙂

At least each folder only contains one disc! But listening through them all is no solution. I mean maybe for once, but each time I’m looking for an album? That would drive me crazy!

So this sent me to the internet in search of a solution. Well, there’s a whole bucket of tools, including Mp3Tag and MusicBrains. Each uses FreeDB – more or less.

For already-sorted albums, Mp3tag was awesome. But I met its limits very quickly. There is no way to look for unsorted files nor does it allow searching by unprecise tracks. For example shorter track lengths come into play, when programs cut off silence.

That’s why I decided to create my own tool. I had following requirements:

  • Offline
  • No query limits
  • Lookup unsorted tracks
  • Lookup with adjustable tolerance
  • Fast response (less than 1 second each disc)
  • Little memory usage
Try the outcome!
