For the Amstrad CPC too. There are a number of production and events every year. The article mentions coding in C++ (which, except for the << operator, is actually C) and with a generic (and therefore a little clumsy) interface to as

To me, the title meant that she understood subtle relations between apparently unrelated facts in life and how to make the best of them. Did not expect that she studied fairy circles on a Namibian landscape. "Instead of office chair p

Some CPUs like the Saturn from Hewlett-Packard [1] are designed for BCD. Though they can perform binary operations, registers are structured for 64-bit floating point operations with a 4-bit wide bus and nibble-granularity addressing of reg

The Game Boy "had" this DAA instruction from its CPU, a variant of the Z80. This trick may well have been used also on some Amstrad CPC games also, then. Indeed, the Z80 itself, which people like us know because it was very common

I don't know if your comment is humour in reply to my humour, or if you're actually kinda hurt. So let's err on the safe side. The short comment "weird trick" that you replied to was just a joke intending to yield a

It might be that photos that are sent to Google get saved with decent compression (0.5 byte per pixel instead of 0.05) in DCIM/PhotoScan. Yet what if I want to keep ridiculous old haircuts private? There's no explicit "save l
