How not to run an open source project:

1) Create a library which quickly gains in popularity.
2) Accept a shared library build as "contrib" with little understanding of the responsibility involved.
3) Change the size of a publicly exported struct, breaking ABI without bumping soname.
4) Refuse to bump soname, claiming you might do it in the future for some more "drastic" changes which may or may not ever manifest.

On behalf of distro packagers everywhere, I think I can safely say: dafuq?

Dear lazyweb,

With Linux 3.14, you might notice in /proc/self/mountinfo that your root's parent FSID is now 0, instead of the 1 that it's been for the last N years. +Tejun Heo wrote the change (9e30cc9595303b27b48) that caused this, but the change comes in a rather innocuous way. Instead of an internal kernel mount of sysfs being assigned 0, it's now the initramfs.

So far, this has already caused switch_root and findmnt (from util-linux) to break, cp (from coreutils) to break when using the -x flag in early userspace, and it's also been pointed out that systemd's readahead code makes assumptions about a device number of 0.

Are we now supposed to go and change all the assumptions in userspace about 0 being special? I'm conflicted. The kernel isn't supposed to break userspace, but it seems to me that FSIDs were never something to rely on -- similar to the block device numbering scheme.

So, this is my view from the back patio for the next few days.

A hugely successful Friendsgiving. Menu courtesy of the talented +Alie Camp and made even more awesome by those in attendance. Highlights, IMO, were the grilled turkey, pumpkin crème brûlée, and mashed potatoes with celeriac. #leftovers   #icantbelievehowmuchiate

A moment of silence please for my less-than-a-month-old bike which was stolen from the busy intersection of Broadway & Flushing. It spent less than 6 hours there locked to Alie's bike. How the fuck? I hope I never meet the pathetic excuse for a human who did this.

I need to break things. I need to kick small dogs.

Really cool find at an insane "antique shop" at the Jersey shore. If this was someone's house, you would have seen it via A&E's Hoarders.

This is a 1920s self-maintaining safety razor kit. It was unused and came with all of the original paperwork. The hone and strop are both in good shape (no cracks!), and the action on the slide is pretty smooth. Needs a bit of cleanup and leather conditioner, but it's pretty neat!

Beautiful, and so English.

Interesting name. Selectively breaking this down, "putz" in Yiddish means penis, and "meister" in German means master.

It's a penismaster.

The machine actually more about plastering than cleaning. :) "Putz" is also the stuff you put on the surface of stone walls.

Quickie tour of John Watling's distillery. They export 2 and 3 year old rum, but their pride is their 5 year old rum which is absolutely delicious. Available only on the island.

Note that the folks you see at the table in one of the pictures is literally their production line. They're hand filling and labelling every single bottle.

Random rooster shot for giggles.

Undocumented, but very welcome Vespa feature -- it's self-shoveling.

That's something I learned: the first part you should clean on snowy days is the license place.
