Dear GNOME devs,

I'm one of the stange people who actually likes the new GNOME3 UI. However, if you take my middle click paste away, I WILL HATE YOU FOREVER (and use MATE).

Jonathan.

Regulator tries to use FoI exceptions (badly) to cover up kowtowing to the industry its supposed to regulate.

Gah, yet again Cineworld Didcot fails to have the new action film (Killer Elite this week). Seriously thinking about canceling my unlimited card if they're not going to have films I want to watch on.

Apparently this is the sound of a peacock's call.

It sounds like an unfortunate cat complaining about its circumstances.

My grandmother had two male peacocks. They were her guard fowls, they would surround and peck a fox to death if it got near the chickens. I always felt they sounded like someone calling for "help!". They also had a deep hatred of their own reflections, to the point of pecking any shiny surface around them. Luckily, on the farm, there is rarely anything shiny.

Victory over nfs4/krb5! I hope.

Kerberos setup was easy. A bit fiddly if the /etc/hosts isn't right (i.e. uname -a and uname -A don't produce host and host.domain respectively).

NFS v4, the important thing to realise is that unless you're on a modern kernel (3.0 or better will do, some very late 2.6.x series work) you need to use weak DES crypto, and pull out various stops to make the system let you do such a terrible thing. I'd just recommending avoiding it/forcing everyone to upgrade to a modern OS.

Turns out that while you /can/ run nfsv3 and nfsv4 on the same server, running both at once breaks the sec=krb5 version of nfs v4 if that host has a v3 share of the same directory exported to it. Disable that and it all works fine.

The really tricky part is making root access to such partitions work. Turns out that root access uses the nfs/hostname@REALM principal, rather than, say, root@REALM or current sudo user@REALM or anything nice and easy. To make the server cope with that you need to use a hack in /etc/idmapd.conf that isn't explicitly written up anywhere on google.

Specifically:
[Translation]
Method = static,nsswitch
[Static]
nfs/hostname@REALM= root

with an entry in static for each machine where you want root to be root.

Those few pieces of intelligence took me the better part of a day and a half to extract and turn into a workable system. Hence my effort in posting them here.

Ran in to yet another person I know at lunch today. I'm wondering if we have a sufficiently critical mass of roleplayers and other types who work at Harwell/Milton Park/Didcot to make a regular lunch meetup viable?

Would anyone be interested?

Well if there was a car able to take people Milton Park->RAL we could use the Electron building (or International Space Innovation Centre as it has been renamed), or probably even the main canteen if we faff with visitor stickers. Otherwise I'm happy to take a car load RAL->Milton Park.

So, experiments indicate that Google+ understands IRC type emphasisi. For example s around a word indicate *emphasis. Presumably /s indicate /italics/?

I'm sure it is non-obvious for some people... right?
