The inner workings of Bintray’s Maven repositories and their inclusion into JCenter are a bit nebulous, but with a few undocumented cues the whole system is actually pretty straightforward and easy to understand.
Since the previous post from about a year ago, the ITEC MediaPlayer for Android has evolved to its second major version, receiving a lot of bugfixes, a rewritten playback core with huge performance improvements, and the ability to playback audio-only sources. Its new name now bumps it to version 3.0 and it is reaching a point where I feel confident that it can be used in production, and in fact, people are already starting to use it.

Resurrecting a dead Huawei B153/B183 Webcube
I’ve got a Huawei Webcube that suddenly would not work anymore. Like often when AC powered devices fail, the problem is a broken capacitor in the power adapter. Here’s a quick guide on how to check if this is the problem and how to fix it.
Yesterday I discovered the free TVUnblock.com service and was suprised how easy it is to use. Configuring my OpenWRT router to get access to US Netflix content only took me about 5 minutes. Being a free service, TVUnblock requires users to register their IP with them to unlock the unblocking functionality. For internet connections with dynamic IP adresses, this means that you have to regularly re-register your IP address, else you’re back to the local program, or none at all if you use it for services that aren’t available outside the US.
To automate this process, I have written a small IP update script:
China 28dBi 4G LTE Multiband Antenna Review
For 8$ including shipping, it is little surprise that this antenna does not fulfill its exaggerated promise. Still, it is an extremely cheap option to get the network signal from the outside to the inside of a room.
Getting the Huawei E3372 LTE dongle to work on a router with OpenWRT 15.05 Chaos Calmer is very easy and requires two additional packages:
usb-modeswitch. They can either be installed through the web interface (System > Software) or by running the following on the command line:

AudioAlign is a tool that I started developing in 2010 for my master’s thesis (and has been actively developed since then), with the goal to create a software for the automatic synchronization of audio and video recordings. Although I never quite reached the point of a fully automatic synchronization system, it showed promising results compared to the few similar commercial applications available on the market, and continues to be a helpful tool for my research purposes. I gave up on the plan to commercialize it due to patenting problems I didn’t know how to deal with, but instead decided on open sourcing it so others could still make use of it and hopefully even help me improve it. Aurio is a library extracted from AudioAlign, providing the underlying core audio processing functionality like an audio processing engine and audio fingerprinting and time warping algorithms. Both Aurio and AudioAlign are now available as AGPL licensed open source software on GitHub.
Conducting high precision audio drift or audio frequency measurements doesn’t have to be expensive. In this guide, I’m showing you how to do it with an ordinary computer, an audio interface, a GPS receiver, and a little bit of tinkering.
