Siemens IOT2050

A few weeks ago Siemens released a very much needed upgrade of the IOT2000 platform; the newcomer is called IOT2050 and is a huge step forward compared to the very very underpowered IOT2040. I have had one for a few days laying on my desk but I just found the time to play with it today.

XMPP audio and video calls

Ejabberd has supported STUN/TURN for quite some time now, this in conjunction with client support can be used to implement one on one audio and video calls.

Apparently Microsoft is not alone when it comes to utterly retarded design decisions. A few years ago when signing up for a Microsoft account I discovered that for some reason they enforce a maximum password lenght of 16 characters or something around that.

Took me at least half an hour to figure out why this piece of trash kept vomiting {"error":"authorization failed"}. …

New Gohugo theme

Since I apparently got recurring readers (no, for real, I do) I suspect someone might actually have noticed how the look of the blog changed drastically a few weeks ago.
