The year 2023 reminded me of my mortality quite a bit, so I took a good, deep look at my home setups in case someone else ever needs to be able to understand it, use it, maintain it. I decided to start with something that we use day to day - music and video playing.

I've been eyeing with FIR (far infrared) heating for years, long before we got to buy our current house. Now we have it, and while it's certainly not a cheap way to heat, it feels lovely; getting here, however, had some unforeseen problems.

I made a smart wake up lamp, just to see if it is better, than a normal alarm clock. It is an insane difference, waking up is so much nicer, and subtle, than before, so I recommend doing one.

Someone, a long time ago came up with the thought that whatever is put on the internet, it'll be there forever. Well, it's wrong. The old versions of my own website, including their design, were long gone, so I decided to put the Indiana Jones hat on, and started digging.

Some years ago I decided to walk away from dynamic website in pursuit of something that feels a bit more, like the small web, and what's more fault tolerant for the future. Unfortunately my solution overgrew its promise so it was time for some reaping.

For many years I used my former ThinkPads as home servers - built in battery, 3G modem, dead silent, sort of too good to be true as a server. Unfortunately my storage needs started to outgrow the options, plus my RAID0 ZFS decided to die within 2 days of the first alert.

I had to install WhatsApp, because some friends are refusing to communicate in any other way, which made me realise how tired and disillusioned I am when I have to face yet another instant messenger network - at least, with some work, Pidgin can still connect to more or less everything and anything.

Nekem tetszik. Bár eddig volt egy belépő, egy közép és egy üzleti-jellegű mobilom (Alcatel OT301, Ericsson T29s, Siemens S55), nekem ő is tetszik. Tény, hogy néhány PIM funciót hiányolok (rendes szinkronizálás Outlookkal, jegyzetek, hangjegyzet), de végül is nem erre tervezték. Fiataloknak és zeneőrülteknem szánták, annak pedig tökéletes.

Szép (formatervezési díjat nyert), jó, rendkívül okos, de túlságosan kicsi. Az üzleti szférát célozták vele, de elfelejtették, hogy az üzletember elsősorban telefonál, aztán a többi - arra pedig sokkal alkalmasabb pl. a Nokia 6310i, ami a színes kijelzőt és a kamerát leszámítva ugyanezeket tudja, csak sokkal kényelmesebb telefonálni vele.
