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.

For 8$ including shipping, it is little surprise that this antenna does not fulfill its exaggerated promise. Still, it is a very 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: kmod-usb-net-cdc-ether and 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 have been actively developing 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 can 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, including audio fingerprinting and time warping algorithms. Both Aurio and AudioAlign are now available on GitHub under the AGPL license.

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 bit of tinkering.

The UA-5 is a rather old audio interface and no longer supported by Edirol. The Windows 7 driver doesn’t work with newer Windows versions, and the alternative of editing the INF file is cumbersome and requires disabling the driver signature enforcement (which is not recommended). There is a surprising solution though.

The ITEC MediaPlayer library for Android has been updated to 1.4.0. This new version mainly improves DASH support, but also has a few bugs fixed, small changes and additions to the MediaPlayer/VideoView API, and improved error/exception reporting.

I am currently trying to solve licensing issues on an unreleased project I am working on and want to get rid of all dependencies under the GPL. One of them is the libsamplerate resampling library, which I have been using for a few years through a managed .NET wrapper. It is just a small wrapper library, but it proved to be working stable. Since I could not find […]

Compiling DLLs on your own can get really messy and take a lot of time (e.g., FFmpeg) if you are not familiar with this stuff. SQLite is one of the positive examples which make it really easy: download the amalgamation source, and follow the DLL compilation guide. Windows users can just use the Visual Studio compiler to compile x86 and x64 versions with a single configuration-less command, and don’t need to fool around with Cygwin/MinGW/MSYS/MinGW-W64/Win-builds etc.

Unfortunately there’s a small detail missing in the SQLite guide, and they don’t seem to have an easy way of contacting them except for an antiquated mailing list. So I’m posting here where nobody is ever going to find it:
