Initially, I thought it was typical burn-out. Between the intense Brazil hackathon (with fglock++, incrementally-built bootstrapping compilers; with cmarcelo++, metaobjects in Haskell for 6.28.0) and moving to a new residence, a few weeks of rest seemed natural.
As the sudden drowsiness and strange non-motivation worsened, I thought it's some kind of mental block, and focused on Jifty instead.
But when external emergencies demanded my attention, all focus was suddenly lost, replaced by massive panic and self-doubt, leading to e.g., the cancellation of my POPL trip just before boarding.
At last, nine days ago, I was hospitalized at the brink of liver failure. Months of intellectualization and analysis was proved immaterial, as there is one very simple explanation: Acute Hepatitis B. The symptoms quickly ceased, thanks to lamivudine, and I expect to be discharged tomorrow, with 95%+ chance of full (immune, non-carrier) recovery.
With the nearest $job/conference safely booked at one month away, I've put various unpleasantries behind me, started populating the new dev.pugscode.org workspace, and resumed Pugs hacking (aiming for a March release of the much-delayed 6.28.0).
So... Stay tuned for backblogs on the progress happened during my absence. Viva la vie! ☺
