Can anyone recommend an IPv6-connected e-mail provider? Preferably one offering solid IMAP support as well as Sieve filtering.

Apparently GNU chmod requires you to be a extra explicit when removing the setuid/setgid bits from directories.

$ mkdir foo
$ chmod 7777 foo
$ stat --format=%a foo
7777
$ chmod 1777 foo
$ stat --format=%a foo
7777
$ chmod 01777 foo
$ stat --format=%a foo
1777
$

Nope, not obvious to me at all.

Woot? I have never used five chars and it has probably been the reason for failures I've blamed on other stuff.

That looks exactly like when n sysadmins cooperate on a task, where n > 1.

Tuesday marks the anniversary of Git, the distributed revision control system Linus Torvalds wrote in a weekend 10 years ago.

I keep forgetting how much I appreciate using GNU Parallel. It's mostly like xargs, just more intuitive, and more powerful.

On a similar note; https://github.com/mfisk/filemap let's you do similar things but on even bigger datasets.

Inte lätt att vara skägglös?

Skäggtrenden måste dö. Den är inte bara skadlig för rakhyvelsbranschen – den är minst lika skadlig för oss skägglösa stackare med barnansikte.

Having native encryption in Ext4 sounds like a potentially good thing.

Ser ut som att Spamhaus just nu svartlistar Portlanes ip-range 80.67.0.0/20, via sbl.spamhaus.org.

Vill man kunna ta emot mail från folk som hostar via Portlane (såsom curl/haxx-folket) gäller det såluna att se till att ens SMTP-server inte blockar hårt baserat på varjesig sbl.spamhaus.org eller på samlingslistan zen.spamhaus.org.

Tyvärr är det ju ändå så att man använder svartlistor utav en anledning. Istället för att blocka utifrån zen.spamhaus.org så har jag nu satt min Postfix att mer explicit blocka utifrån xbl.spamhaus.org och pbl.spamhaus.org.

Spamhaus is now escalating against Portlane due to the high amount of unresolved SBL listings. We strongly recommend Portlane makes the necessary adjustments to deal with abuse on its network in an timely fashion. If you're a Portlane customer and this SBL listing is affecting you, ...
