Zompist Bboard Again

zeptoforth now has preemptive multitasking which works! (One can still manually hand off control of the processor with PAUSE though if one wishes.)

The "which works" part is important, because I had this almost complete for a while now, but was running into problems that turned out to be due to an undocumented bit in the ARM Cortex-M4 exception frame format.

And now I can officially call zeptoforth an RTOS, as it now has task priorities!

Furthermore, for more RTOS goodness, it now has a lock implementation that resists priority inversion even when multiple locks and tasks holding them and waiting for them are chained together!

I bought my favourite Kenyan black tea. Best thing ever to get up in the morning (and by get up I mean 'get a caffeine overdose').

I reworked priority inversion-resistant locks so now they work properly in the case where a single task holds multiple locks, each of which has another task waiting.

Is that the issue you mentioned in the other thread as having stumped you for a week? Congrats on getting it working!

Yes it is. The problem when I fix bugs, though, is then I soon get dissatisfied with not having much to do, and have to keep on thinking up things to code so I don't get bored.

I just applied for graduation for my masters degree at the end of next semester!!!



It's gettin' real, now!

Congrats! What'll you get a master's in?

Thanks!

The short answer I give people is "digital media". Long answer: MA in Media & Information (UX design focus) as well as a certificate in digital media from another program in the college (Strategic Communications) via elective classes.

Nice! UX design is a particularly interesting subject.

Congratulations from me, too!

Thanks to you as well! (But still just from me. )

I wanted to gift a friend’s kid a vinyl copy of Yellow Submarine. It’s been in the mail for over two weeks with no delivery date in sight. This morning I remembered that I myself had a copy of Yellow Submarine on vinyl and that it hadn’t ever been played. So I located it and sent it via UPS this morning. When the second copy finally arrives I’ll just hold on to it.

My semester is finally over.

Huzzah! These days, any semester you survive is a good semester!
