Wi-Fi Sd Cards

My latest weekend project. Making a normal digital camera WIFI enabled. With the Transcend Wi-Fi SD Card you can convert any digital camera into a Wi-Fi enable camera. What I did here is to set it up so that it would automatically upload photos whenever I turn the camera on while at home. The nice thing about this camera is that it runs a fully functional Linux environment within the card. The manufacturer was also nice enough to give you the opportunity to customize the card by running arbitrary shell scripts from the SD card itself. My code is in github. ...

In order for FS-Cache to operate, it needs cache back-end which provides actual storage for caching. One such cache back-end is cachefiles. Therefore, once you set up cachefiles, it will automatically enable file caching for NFS shares. ...

atratus project

The other day I came across this project. Looks an interesting idea. It is a project that lets you run unmodified Linux binaries on Windows. It is more similar to WINE than to for example coLinux. While I conceptually I understand how it would work at a low level, I am curious how it works with dynamically link executables. This is something I would like to test out when I have time. ...
