implementing mailman and postfix with lighttpd on debian
I recently needed to set up a mailing list for a group of friends (my bike club). I had become tired of mail bounces and failures because we were all relying on an out of date list of addresses originally cobbled together by one member. That list of addresses was routinely used in “reply all” …

vinyl to digital
Recently you may have seen adverts in a wide variety of publications for a USB turntable. This product is aimed at people (like me) who have a collection of old vinyl recordings but no longer have the means to play them as they have moved to CD and/or digital recordings.
