go for it but make a 68000, the objectively superior architecture but make a 68010 since it can actually resume an instruction after an exception

nah there’s no reason not to use Musashi for the 68000 family, even MAME uses it if you want a challenge, upgrade your 8080 to a Z80! there’s a PDF on the internet that’s a 30 page description of how the Pac-Man hardware works

no do a fancy emulator like the table-based 68K emulator with deterministic timing that Apple wrote for PowerPC so even interrupt level code would just work

ctps: My current Go gripes: So, being a .Net programmer by trade, I've grown accustomed to using cancellation tokens when I have multiple layers (both vertically and horizontally) of async calls that I need to shut down all at once when something goes wrong or a connection dies or something. Go has something sort of similar: context. If you don't use contexts you end up having to create these things called signal channels, and you can monitor this channel in all your goroutines and when you close your signal channel (because one of your goroutines wants to shut everything down) your goroutines can all watch that channel and return out of their functions when it closes. Ok, fine. With context, you get the same functionality, but it has the channel built in, as well as built-in support for timeouts and some other stuff. An n-tier set of services, correctly using context, will all shut their connections down gracefully when needed. It's kinda nice, allows a bit cleaner code than having these lovely signal channels all over the place. Well, i'm now running into people in the golang community that loving haaaaattteeee context. It's been called a virus, for example, because it "infects" all layers of your code, which is kinda funny to me because I've seen the same argument against using async/await in .Net. In my mind, it's like decrying exceptions because "now we have try-catch all over our apps... you should just return errors :P", which is also a thing in golang, lmbo. I was told by one golang package maintainer that context is not idiomatic because you can accomplish the same thing without using contexts. Isn't that like saying "You can accomplish the same thing without using Go... just write assembly :P"?

the problem was that context was popping up in apis it had no business with. like you should absolutely use context in a web service context but people were using it solely as a scoped key-value store where a custom 'context' struct would have worked much better. but yes, the backlash is real and stupid. the go community really struggles with concepts like 'sometimes thing good, sometimes thing bad' if you introduce context, it will spread like a virus. if you introduce generics, the language will be instantly transformed into enterprise java.

leper khan posted:you people and your 8080s. try implementing something fun and esoteric, like a belt machine. if your want real fun, build the whole thing in VHDL after your emulator is working. back in my university days (~10 years ago) i put together a dedicated machine in VHDL that synthesized a VGA controller, ram controller, and a few shift registers to interface with a NES controller, as well as an instruction set dedicated to playing a tank game like the old atari game. it was cool having a dedicated "bullet" instruction. i don't think i could do it again, though.

laptops are the loving worst. if you work with computers your employer should at the very least have the god damned decency to provide you with a workstation - a real computer that can actually use its cpu without thermal throttling after thirty seconds, and that you can actually repair, not one of these small plastic toys urging you to bring work with you wherever you go. for too long we have accepted the mountain coming to muhammad as natural. physically leaving your desk should be equivalent to mentally leaving work behind. bringing your loving laptop with you is dysfunctional as gently caress.

terrible programmer status: I couldn't figure out why my shading routine didn't work the formula for finding the shading ratio of a vertex is: take the dot product of the normalized vector (light_position - vertex_position) and the normal after transformation I was projecting a vertex, then normalizing (light_position - vertex_position)  now I have a cube https://twitter.com/LuigiThirty/status/1034337242196652032

Experimenting w/ our legacy codebase last night I found that our application doesn't start its idle timer until a few steps in to the login process, so you can leave the screen on a confirmation window and then leave the software open overnight. This is accounting software that cares A WHOLE BUNCH about date/session ranges to do accountability reports on where money goes  Also the idle timer is a single DispatchTimer with a 15 minute Interval that just locks the program on Tick, any anytime you do something that matters enough, it resets that timer and makes a new interval, which can't start until the current one has ended. So if you're idle for 7 minutes then do something, your idle timeout is now 22 minutes instead of 15.

I have a random dumb question... What does it take to do consultancy? Like, if I wanted to offer consultant services as a "highly experienced" software developer and architect, do I need to know anything beyond cs basics and various software designs? I feel like I could easily go into a business and tell them how they're doing everything wrong, and come up with a plan for fixing things. Anyone here do this kinda stuff or is it really awful somehow?

i've kinda been wondering about the same. the most convenient thing for me ATM would be to establish a freelancing/consultancy business, so i can focus on going back to school or whatever i want while still paying the bills. while i've got the experience to back it up, i'm really not great with strangers and would not enjoy having to deal with a revolving door of new, demanding faces. also i'd probably let myself be a doormat and would have a hard time saying no to unreasonable expectations.

IME, sometimes it owns, sometimes it sucks. If you can keep the doors open and bills paid then it mostly owns. Oh you want to gently caress off out of town for a couple days mid-week? Great! You want to knock out a project and take a month off before the next one starts? No problem! However I'd say the number-one hard requirement is a solid pipeline of work, however you come by it. Someone in here mentioned that consultants live and die by billing and it's super true. It's tempting to get wrapped up in a project doing the fun stuff and forget about beating the pavement for the next bit of work, especially if you're delivering what feels like a big project for what sounds like big money. It's probably not as much money as you think it is and it always takes longer to get it in the door than you expect. At least you don't have some dipshit boss telling you how to live your life, because the dipshit boss is now you!!

My personal gold standard of consulting life goals is a story I heard from a friend who worked for a metrology product manufacturer. There was a dude with a box that they would hire every so often to come in to the facility. They would put a device in his box, he would press a button, and later on a report would pop out, along with an invoice for >$100,000.
