Nokia (mostly networking-related things nowadays) touts - or at least used to, haven't kept up to date - itself as one of the most ethical companies around. > But isn't that true for every big corp, or even every public company? So I suppose not really, no. Additionally companies working on carbon-free energy might also serve as evidence. There are some big ones around.

> Additionally companies working on carbon-free energy might also serve as evidence. There are some big ones around. Interesting exemple because the biggest investors in renewable by far are big oil companies. So what should people do? Go or not go? Sadly, the world is never black and white.

I think people should do/go where they have a peace of mind, whatever that place may be.

> They also got me reported to HR by the manager of the XROS effort for supposedly making his team members feel bad I've only seen John Carmack's public interactions, but they've all been professional and kind. It's depressing to imagine HR getting involved because someone's feelings had been hurt by an objective discussion from a person like John Carmack. I'm having flashbacks to the times in my career when coworker…

> They also got me reported to HR by the manager of the XROS effort for supposedly making his team members feel bad This is one of the reasons I’m sick of working pretty much anywhere anymore: I can’t be myself. Appreciating people for their differences when they are humble and gifted is easy. I side with liberals, but I have a mix of liberal, moderate, and conservative friends. But there are only so many years of pr…

If the younger generation is too pandered and can’t take criticism or honest feedback, thats the fault of the older generation.

You don't report someone like Carmack to HR, it will only backfire and make your ignorance even more visible. Also, I am not surprised he was reported -- typical underhanded political hustling commonplace at Meta.

Report whoever you want to HR people. Don't listen to this guy ^

Hopefully for a better reason than the report against John Carmack.

Wow... that PDF is 2,750 pages! There must be an army of technical writers behind it. That is an incredible technical achievement. Real question: Why do you think Intel does this? Does it guarantee a very strong foothold into data center NICs? I am sure competitors would argue two different angles: (1) this PDF shares too much info; some should be hidden behind an NDA, (2) it's too hard to write (and maintain) this P…

Look up the Texas Instruments am3358. It's a tiny SOC, it was used in the beaglebone black. Its technical reference manual[1] is over 5000 pages, and it details all peripherals, all of the interconnects and every single register in the system. This, by contrast, is really just an overview. Regards to (1), if you don't publish this information you're not selling a CPU, you're selling a very expensive chunk of sand. Th…

I worked on a similar TI SoC -- with War-and-Peace-sized datasheet. My eyes burned out and brain exploded. Ultimately, another engineer had to take over the project -- or rather TEAM of engineers, of which I did only a part. It's simply to much complexity to expect one engineer to grok it all, do the schematic & PCB & power supply & hi-speed MIPI connections and radios and... and THEN to write the software for it all. It's too much. (This is the Life one gets in Startups, it seems -- worked to the (beagle)bone!)

People are nailing it here -- it's not the "OS" per se (heck, look at CP/M or original unix and this gives you a floor) -- it's the drivers and the required Standard Pieces: DMA, memory protection, TCP/IP, BLE, WiFi, Ethernet, GPU, USB (+ vast USB drivers), etc. Lotta 'standard' software must work on any new OS + drivers for all that hardware that is always changing. Great 'fun' .... Now, I do think Minix had a chance for a very short window, but lack of resources made sure it's now only an OS history footnote. All because a microkernel sucks 3% performance away from monolithic kernels. We are confused as an Industry... Performance uber alles -- that has just GOT to get fixed. Security; maintainability; simplicity > performance; or rather, those are worth some performance degradation.

Masters of doom portrays carmack as a total dictator of a boss. Doom Guy by John Romero seems to back this up

Masters of Doom does seems to want to, however accurately or not, set Carmack up as the antagonist of its story against Romero as the hero sometimes. I think that readers just largely didn't notice that since Carmack's heroic image was already so firmly established. In fact some of the early-ID stuff really does seem to raise some questions. (Was Tim Willits mostly Carmack's protégé, for instance?)

yeah and Doom Guy takes a lot of issues with Masters of Doom. You get the impression that MoD was looking to create a McCartney vs Lennon story and stretched the truth to do so (there are several factual errors in the book).

In Doom Guy, though, Romero says that after he left iD, he heard from others still working there that the company had become something of a dictatorship under Carmack, and that within X months (I forget how many), half the company had quit. Romero also qualifies several times that they were all in their early/mid-20s and didn't have the requisite life experience to be handling business situations well

You've done some great work but I have to call BS with this claim: > I'm the only person who ever implemented all of it. Sean Baxter is an easy counter example.

I don't know much of anything about him. Did he implement the preprocessor? the optimizer? the code generator? (For some context, back in the 80's, code generators needed enhancements to implement C++. You couldn't just use an existing one. Bjarne had to do some ugly workarounds because of this.)

Sean Baxter's circle compiler uses LLVM as a backend, but I believe the rest is from scratch.

Arguably these days having a clear frontend/backend separation is good compiler architecture. It might slow down compile times a bit, but it's worth the cost.

Was at Oculus post acquisition and can say that the whole XROS was an annoyance and distraction the core technology teams didn’t need. There were so many issues with multiple tech stacks that needed fixing first. Mind you, this XROS idea came after Oculus reorged into FB proper. It felt to me like there were FB teams (or individuals) that wanted get on the ARVR train. Carmack was absolutely right, and after the reorg…

Love this idea and wondering where that low cost of living place would be. But genuinely asking; What problem are we trying to solve that is not possible right now? Do we start from hardware at the CPU ? I remember one of an ex Intel engineer once said, you could learn about all the decisions which makes modern ISA and CPU uArch design, along with GPU and how it all works together, by the time you have done all that…

Software is bloated and unreliable. It's clearly a "local minimum".

If it's so bloated then just start cutting

Whatever expertise you need to prune a working system is less than the expertise you'll need to create a whole new one and then also prune it as it grows old
