Nowdays we're all concerned about environment and our impact on it. At the same time security concerns do not allow our conscience to agree on these cloud bells and whistles.
Luckily we have now available at the consumer segment low profile and power consumption platforms like Raspberry PI and others. Compare 1-2W of raspberry to at least 10-20W of any other HTPC. Such platforms however have certain resource restrictions.
I've recently bought probably the best laptop I've ever had - Lenovo E130, with probably, the worst OS I ever had - windows 8. Initially, knowing Czech distribution is in any case one of the worst in the world - I didn't bother much, and bough whatever model was available in local shops (you don't have a choice in Czech Republic really, never, only crappiest things available).

If you use some system for long enough, passing through various release upgrades, installing and uninstalling packages - basically living and using - your system might start be bloated with various remnants of dependencies, unneeded packages, dragging back some relicts or even blocking some new deps. Very unpleasant fact.

While working on jack IPv6 network stack I've trapped onto bizarre getaddrinfo() behaviour - it was returning me address families in wrong order for passive nameless request. It appears people were trapping onto this bug since 2009 (at least that far I found references to this behaviour in mail-lists).

If you're using dhcp for both ipv4 and ipv6 on ubuntu with wifi/wpa_supplicant you might have faced with weird issue with ifdown trying to release v6 (or v4, depends on ordering) lease and it finally hangs - since previous address family already brought interface down.
