I’ve seen and had ‘make -j’ dos machines enough times that I consider it a bug.

I find these type of efforts somewhat disappointing. So much OS research boils down to “We’ll handle scheduling and rudimentary peripheral multiplexing good luck on rest”. These basics are so far from a useful system that you’d have to slap

When I was last working with machine code, I found capstone to be very useful. Even just reading the source was helpful for some of the conditionally present amd64 fields. https://github.com/capstone-engine/capstone

What I’m thinking is more like the Gov being able to furnish key designs to organizations that can plausibly iterate on them. So orgs don’t have to make massive investments to catch up to and integrate SotA phased array radars, flight contr

I’ve started to think that the Gov. needs to act more like a pseudo open source maintainer rather than customer or designer. Competition helps on many different axis, but the gov not owning the designs (whose R&D we paid for) drasticall

Not sure I agree. If you’re going zig->C->obj, you’d still have to fix the zig source if you find an issue in the C level. If you don’t want to learn or debug in a new language then you should probably just stick with C? The goal of z

So you can just extern the functions you want, handle all the errors internally, and stick it into your makefile with? %.o: %.zig zig build-obj *.zig -o *.o Not sure I get OP’s complaint then.

I’m using zig for embedded builds currently. All of the mcu files are still in C (arm thumb isn’t first class supported in zig) but the host software is sometimes zig. Being and to easily develop on and for any host platform is such a pleas

Replacing C != coexisting seamlessly. Exposing an idiomatic C interface by default would handcuff Zig’s own design. > Having to know the full set of Zig sources in advance due to error types You can just catch all of the errors and trans

My current project is a huge C++ physics sim written over 15+ years. The most common and difficult to diagnose bug I’ve found is unit conversation mistakes. We likely wouldn’t even find them if we didn’t have concrete data to compare agains

I would consider a PCB schematic to be part of an electrical schematic. Even if you don’t, you still have to consider final layout because some lines will need EMF protection. The linear equations and boolean algebra are just a (extremely u

Not entirely true. Routing is a very important part of electrical schematics.

The US has really poor highway policy that encourages speeding. Many highways have a speed limit of 55mph (89kmh) left over from some ancient oil rationing law. [0] So folks are conditioned to think that speed limits are stupid, because fra

I’m not much of a gear head but I believe that a car would perform much worse at 0-80mph if it couldn’t physically reach 120mph. You can artificially limit it and I think that’s what folks take with.

The problem is resistance and parasitic capacitance scales with wire length, e^(-t/RC) is going to limit your max frequency.

Computer scientists continue to pick terrible names. Pipelining is already an overloaded concept that implies some type of operation level parallelism. Picking names like this does everyone in the field a disservice. Calling it something li

I’m not sure. Command based editing opens more doors than just optimizing keystrokes. There are edits I somewhat regularly do with Vim macros that save me minutes of typing and cognitive burden of examining refactor locations. It’s probably

Yeah, I’m leaning towards zig but I’m a bit on the fence still. For Rust, I kind of got tired of writing unsafe rust for embedded, but that’s addressable afaik. The real dealbreaker was that after 10k+ lines of code I still will pop open th

Let’s not pretend that Apple could come up with some sort of dual windowing system (or just dual boot) scheme. We’re not limited by drive space anymore. They don’t because it would hurt macbook sales.

“You will own nothing and be happy.” includes public ownership through your government I guess.

For sure. Maybe less accidental complexity. Embedded has been doing asynchronous IO since before it was cool. You also have distributed computing if you’re doing something like sensor networks.

While I don’t think we should be hoarding vulns, the idea of the government having huge budgets to find and disclose software defects is a bit strange to me. Seems like another instance of socializing bad externalities.

I’ve written a fair amount of Makefiles and bounced off of cmake. Recently I’ve started using zig to build some C++ projects and will not be switching back. Having your build tool just be a library in a good general purpose language is the
