Writing. 121 lines, 965 words, 5836 bytes, and all about writing files of all things. It really did take all afternoon, for not very much usable output. Some days just go like that. I mostly discovered what I should have been writing, which is a piece in three (four?) parts.
- How badly file creation is currently being done
- That interstitial bit between writing and reading, which leads to exploitable race conditions
- Reading is not so much a problem as parsing, which has been a gold mine of exploits over the years
- Possibly a lead-in bit, which I am attempting to dodge by posting this
An additional problem is how to present the material, as an introduction to the subject, without it being an off-putting wall of text. For instance, introducing hexdump to beginners, as well as a few programs in core-utils, all in text, turns out to be non-trivial. This stuff is a lot easier when you can just get in front of a whiteboard in scribble-yack-enjoy mode.

Comments on posts older than 60 days go into a moderation queue. It keeps out a lot of blog spam.
I really want to be quick about approving real comments in the moderation queue. When I think I won't manage that, I will turn moderation off, and sweep up the mess as soon as possible.
If you find comments that look like blog spam, they likely are. As always, be careful of what you click on. I may have had moderation off, and not yet swept up the mess.
