RAID5 corruption is non-recoverable - you can't tell which is right, the data or the parity. RAID6 is recoverable - you can get consensus between the data and the two parity bits. ZFS stores hashes of each block, so as long as you have two copies, you can just pick the data+hash that's correct and restore the corrupt block, even with only two copies of the data.

On the last round of zpool scrubs of the 13PB-used set of zfs filesystems here (raidz3, mostly SAS drives, all hosts with ECC RAM), 50MB of data was repaired.

50MB isn't much compared with 13PB, but silent corruption is a real thing.

It's not very common, but there's more than a few projects that use 'learned':

I stand corrected!

There were genuine reasons for the CDDL - it wasn't an anti-gpl thing. https://www.youtube.com/watch?v=-zRN7XLCRhc&feature=youtu.be...

script unfortunately messes with SIGWINCH for terminal resizes - asciinema seems to work better in that case.

Engineers blogging about Solaris etc. Internals, gotchas, upcoming things, heads-ups on problems. The patching guys' blog was particularly useful in the face of Solaris' atrocious packaging utils, for example.

There was a _huge_ amount of official-unofficial documentation in the blogs that disappeared from the Sun site when Oracle ran its bulldozer through it.

iTerm2 can copy selections to the system clipboard. That alone is worth the price of entry.

More of an IRL comment - I get recruiters looking for people in Edinburgh at least once a week. Not a peep about tech in Glasgow though.

Lots going on in Edinburgh, not so much in Glasgow.

Anyone know why that is?

21 spare nails, 2 spare shoes.

Or 3 horses with a limp and a spare nail.

It sounds very, very much like you are depressed. You should seek medical advice.

I don't think there's much else to say, really. Get well, and the rest will follow.

That CPU use is resampling to match the sound card rate. If PA isn't doing it, your apps will be instead. Either way, it's going to take some cycles.

I've had a .name email address since the TLD was released. Never had any problems with validators.

'Name' is a surprisingly easy word to mis-hear over the phone if it's not expected, though.

$ emacs <file>

C-x h <tab>

Whatever that does, with whatever type of source file, that's what I'm using.

Government (SLC) student loans debts aren't sold off in the UK, so... no.

I'm a big fan of Zabbix for general server monitoring and alerting. Sensible defaults, built in graphing, multi-step web scenarios. Good times.

You can rely on config management if it pulls from a central service and that central service reports failures and hosts not checking in.

My MBA locks up about once a week. Seems to be triggered by closing Firefox tabs with Flash content.

The only Windows BSOD I've seen since Win7 came out has been from a dodgy stick of RAM. A stick of RAM that then got passed around a few of us at work to ensure timely laptop upgrades.

No software patents in Europe (well, not officially anyway).

Good call.

Depends if the backup's on the same filesystem as the source.

Missing some options for extended attributes (SELinux, ACLs) and (on OSX) resource forks.

Also, if you're doing multiple backups of the same data to a filesystem over time, it's worth doing 'cp -al' from the previous backup to the current backup destination, then rsync over the top of that - that way multiple copies of files which haven't changed don't take up any extra space.

Name and shame.

PuTTY's pretty much relegated to the emergency usb key these days. Runs on pretty much any Windows and without installing, but not really ideal for heavy use imho.

Cygwin + urxvt + clusterssh is the choice of Windows-mandated champions.

An article claiming that only 11% of findings could be reproduced doesn't cite its sources, thus rendering the findings of the article unreproducible. Nice work!

True. Unfortunately Firefox had a bit of a moment to itself and did the looping sample thing, then hung while playing.

It was so loud. There was no escape.

Had to pull the battery to end the ordeal.

Well. My speakers were at full volume and I'm in the middle of an office with 400 people.

I'm off to hang myself.

That makes me feel kind of sad. A once-mighty machine waiting hopefully in the dark for an Operator to load a tape.

But the Operators never arrive.
