This service allows you convert a Flash Video / FLV file (YouTube's videos,etc) to MPEG4 (AVI/MOV/MP4/MP3/3GP) file online. It is using a compressed domain transcoder technology (outline in Japanese). It converts FLV to MPEG4 faster and less lossy than a typical transcoder.
When you submit an url, it will download and convert to the video format. Then you can download the converted file.
FLV to MPEG4 Conveter engine is now OpenSource. You can download the source code via subversion: http://sourceforge.net/svn/?group_id=183657
Use Nitter to browse Twitter while retaining your privacy. It's a free and open source alternative Twitter front-end focused on privacy.
It's basically impossible to use Twitter without JavaScript enabled. If you try, you're redirected to the legacy mobile version which is awful both functionally and aesthetically. For privacy-minded folks, preventing JavaScript analytics and potential IP-based tracking is important, but apart from using the legacy mobile version and a VPN, it's impossible.
Using an instance of Nitter (hosted on a VPS for example), you can browse Twitter without JavaScript while retaining your privacy. In addition to respecting your privacy, Nitter is on average around 15 times lighter than Twitter, and in some cases serves pages faster.
