IMAP MOVE is under way

A single-document working group has been formed, and I have submitted the document for publication. It's not visible yet — wheels have to turn in the IETF secretariat first.

I hope this will be a peaceful process resulting in a readable RFC and wide implementation. So far it looks good, no flames and about nine servers implement it.


More on Ubuntu 12.04 and the Nokia Booklet

I've written earlier that Ubuntu 12.04 runs well on the Nokia Booklet. True, it does. But I glossed over the pain of installing. Sorry.

My first problem was that I had installed an SSD, and the 3.0 linux kernel, the chipset and the SSD weren't friends. The installer would die immediately after partitioning the disk.

I got around that by booting ubuntu (actually kubuntu) from a USB stick, choosing try kubuntu, connecting to a wireless network, opening a terminal and (more…)


Fault tolerant programs and programmers

Archiveopteryx git head crashes a bit. Not every day, but some people reports that it crashes every week or month, at random times. Clearly there is a bug. Abhijit and I have discussed it and found a way to contain it, and I've written the code.

But I haven't found a way to push the fix to the master tree. I seem unable to commit and push that code. My soul wants to find the bug and fix it, not contain it.

Meanwhile, I had an appointment with the dentist this morning.

In the waiting room I read a fascinating blog post about a Chromium exploit. Sergey Glazunov, clearly an admirably clever hacker, stitched together fourteen bugs, quirks and missed hardening opportunities to form a critical exploit. The bugtracking information for one of the bugs shows that it was reported, discussed for a few days, then it was idle until Sergey leveraged it, and then it was fixed.

Chromium is a nice browser, and I appreciate the hardening and exploit resistance the team has added. I particularly appreciate the team's honesty: They run their pwnium contests and are frank about the results.

But now I am even less happy about making fault tolerant code. I feel that it may be mentally difficult to make a program tolerate faults and at the same time make a programmer not tolerate faults.

Full-disk encryption: Luks and ecryptfs

A brief aside, almost a rant: Ubuntu offers a way to encrypt home directories, ecryptfs. There is also a way to encrypt everything, luks.

Luks is the better alternative. (more…)
