Exposure to production systems is a new advantage you have. You can learn a lot from the failures and problems. If your workplace has written postmortems, read them. Ask more senior engineers about the times things went wrong. Figure out ho

A subset of CP/M calls is a pretty simple "rest of the system" to implement on top of an 8080/Z80 CPU emulation. (It's a bit of a cheat - like qemu's "Linux user mode emulation" or early version of DO

Agreed. I wanted to script stuff like linking together 200 .OBJs, and running tests' stderr through sed to make it comparable with a known-good log. A DJGPP install + ancient Python inside DOSBox would've also done the job. Or eve

Is it possible that this proliferation of SKUs is how Intel gives each of HP, Dell, Lenovo, Acer, etc exactly what they are asking for? (I presume, if you buy enough Intel CPUs, you have purchasing managers who are constantly chatting back

Core infrastructure (domain registration, SSL certs, IP addresses, peering exchanges) mostly need administration and maintenance . But NGOs in this space seem haunted by a compulsion to do more. It's interesting - and possibly corre

Thanks. On reflection, I have something that identifies as "9.5" but it might be 9.5B. I've found C32_B.ZIP and I suppose I can try to compare it against the install. I'm quite confident I don't have 9.5A! I've

Apple will sell you a low-profile chiclet keyboard that feels a lot like an older Macbook Air. I have one at work. I've got a daskeyboard (Brown switches) at home. I think both chiclet and mechanical keyboards give me tactile feedback

I'll speculate. Companies started making these things in the late 90s, when it made sense. In 2020, it might make sense to keep selling drives. But nobody would start making and selling these drives today. A few things happened aro

A profiler will often reveal an interesting cross-section of the code that you can read first. Any way to get a stack trace can be a rudimentary profiler, just keep looking at stack traces until you see what comes up most commonly. If you&#

Different versions of the chip (different manufacturers, integrated into a larger IC..) just laid the RNG out a bit differently, I'm not sure what the reasons were. There's a detailed comment at the top of MAME's emulation co

I think it'll be all right. python3.8 is its own distinct package, which will install alongside the existing python3.6 . Debian/Ubuntu's "alternatives" system can select what /usr/bin/python3 run
