Met a retired teacher who sold me a bucket of slide rules for a dollar. If you ever see us dock in your local harbor, I'll give you one and show you how to use it.
c. Bug in silicon; if serial and timer interrupted on same clock cycle, both routines executed, but only one address would have been pushed to stack. So, crash. That could be detected in software, and work around sent to Microchip.
d. Stack is in hardware, only 7 levels deep. So, one level per interrupt. Plus one level wasted for the work around above, left only 2 call levels for the code.
I made this device in 1997;
1. EXOline protocol on RS-485
2. I2C to talk to EEPROM with calibration parameters.
3. SPI to talk to D/A converter
4. 1-wire to communicate with up to 8 external DS18B20 temperature sensors.
All done in a Microchip PIC16C73, which has 192 bytes and 2k PROM.
Challenges;
a. maximum size of EXOline packet is ~240 bytes, so couldn't buffer the whole packet.
b. Each 1-wire has a 64 bit address, so 1/3 of RAM for those addresses.
Somehow past defenders of liberalism now want an illiberal internet. Don't be surprised. Every generation tends to think the next one can't think for themselves. They actually come to trust corporations more than the people. Please reject that impulse. #fediverse #LiberalValues

In virtue of my heretically archaic views about biology and the importance of women’s rights, I’m the target of quite a lot of rude online behaviour. The other day, for instance, I learnt I was lucky I hadn’t been hanged yet. So you might expect me to be emphatically in favour of attempts to remove what the Online Safety Bill calls “harmful communications” from the internet.
This isn’t the case. In fact, I think the Bill’s proposals on this kind of internet content are a dog’s dinner. If implemented, they will undoubtedly suppress desirable levels of freedom of expression on the internet, and cause more problems than they resolve.
i'm increasingly happy that i took the right bet not taking that stuff.
