C originally had =+ and =- (upto and including Unix V6) - they were ambiguous (a=-b means a= -b? or a = a-b?) and replaced by +=/-= The original structs were pretty bad too - field names had their own address space and could sort of

Burroughs used an Algol60 derivative (not '68)

by Taniwha 11mo ago
I would argue C comes from Algol68 (structs, unions, pointers, a full type system etc, no call by name) rather than Algol60

Linus recommends SMD parts kits that are quite expensive, and relatively bulky, I prefer the books of SMD components, they're more compact and ~$15 each and you can buy refills for ~$5. For things you use a lot of (1k/10k resistor

There's an SF short story (Larry Niven I think) about a seismologist who predicts the big one, but the math is not quite right, the story gets out, panic ensues everyone heads for Nevada, he guy is still working in his lab trying to fi

Showing a completely legal electronics market in HQB in Shenzhen and claiming it's selling stolen phones is rather unfair - there is a building not far from that market that sells and recycles phones mostly by stripping them for parts

I think the metastability can't destroy a chip thing is not true, you can get a flop into a state where it's oscillating at whatever freq the internal feedback path is (maybe up to GHz) rather than resolving to a stable 1 or 0. Th

Yup, M2 had 81-bit instructions, M1 had 72-bit ones

Not really - I worked on a DSP with 9-bit bytes in the 90's (largely because it was focused on MPEG decode for DVDs, new at the time) largely because memory was still very expensive and MPEG2 needed 9-bit frame difference calculations

Wirth was on the Algol68 committee - I'm sure he understood how those sorts of unions worked. He also avoided a lot of the more advanced features of Algol68, he thought it too complex, when he designed Pascal

I made a living porting Unix to new hardware in the mid to late 80s so all the busses of the day came across my desk, and designed graphics card silicon in the 90s S-100 was very much history by the time the boxes in the article were design

Algol-68 gets a bum rap here - it brought us 'struct', 'union' (and tagged unions) a universal type system, operator declarations, a standard library, and a bunch more - Wirth worked on the original design committee, Pas

I'm a sometimes CPU architect and came here to argue just this - modern CPUs have far far slower memory access (in clocks) than z80 memory access. To be fair you can probably fit any z80 table you're using into modern L1 cache, bu

Branch hint instructions essentially give you the initial value for your BTC entry, after that you want it to learn - in general though if you initially predict backwards branches and don't predict forwards ones it's almost as goo

When you have a president who can predict the paths of hurricanes with a sharpie you don't really need all those expensive satellites.

They don't have datasheets up for the modules yet sadly Can anyone answer my question will the C5-WROOM be a pin for pin dropin replacement for a C6?
