redis and hiredis added to Gentoo Overlay

23 December 2012, 1 minute to read

While I was writing some more code for songride I felt that I should have the latest redis version installed. After running emerge '>=dev-db/redis-2.4.17' I was confronted with the following error message:

Re-emerging redis fails too with:
    LINK redis-benchmark

As I this is a problem affecting all Gentoo installations since the upgrade from jemalloc from 3.1 to 3.2 the Gentoo Bug #444796 was already solved and contained an ebuild for redis-2.4.17 that would install fine. Sadly this ebuild is not yet available in the main portage tree so I added it to my overlay.

Another useful project when using redis is hiredis, a minimalistic C client library for which an ebuild is available in Gentoo Bug #440226 but not in the main portage tree. The ebuild in my overlay contains the modification suggested by alexbr.

Both of these ebuilds are GPLv2 licensed so there was no problem in adding them to the overlay.


ktoblzcheck bindings for Node.JS

Checking the correctness of a combination of bank identification number (BLZ) and account number is a complicated task in Germany. There are about 140 different methods how this combination is checked depending on the bank from which the combination originates. A library which solves this problem is ktoblzcheck. At the moment you could use it simply as a C++ library or with the python wrapper but there isn’t a simple way to use it in Node.JS. Due to this lack of support I wrote node-ktoblzcheck. Until now it supports the two main functions I needed.


spotify- added to Gentoo Overlay

Some weeks ago Spotify released a preview of their new discovery features and gave some people the option to test it on Windows or Mac. Last Thursday they released their discovery features for the linux version.
