Bad headache started last night. And not my usual one. (Tho it's in full flower.) And it lasted all night, and all morning. Coupled with bad fragmentary dreams in code of the coding du jour. (This is something the only coders can understand, and nobody else. Not dreams *about* code. Dreams *in* code.)
Not just *a* headache. One that is both very bad, and seems linked to concentration.
I think I broke my brain.
Stayed home. Send an email saying that the deadline is going to get blown. Again.
