therealcamino··on Xilinx HBM2 Internals (2023)
Yeah, I found the Conventions section baffling. It defines both "giga" and "gibi" as 2^30! Why define both if they have the same value? Then it confuses the issue further by using "gibi" when the underlying unit is bytes, and "giga" when it is bits, which, given those definitions, doesn't convey any difference in meaning.
therealcamino··on Us revokes Intel, Qualcomm licenses to sell chips to Huawei
I think you are a little optimistic that the full EDA flow would be "not... particularly difficult to write." On the implementation side alone, you'd need to write a SystemVerilog compiler, logic synthesis, timing analysis, timing optimization, power analysis, clock gating, coarse placement, global routing, detailed routing, placement legalization, physical design planning, clock tree synthesis, design rule checking, lots more underlying technology to make it work, and lots of steps I'm not remembering. Every one of those sub-areas is it's own specialty. Then you can start thinking about verification.
therealcamino··on General Motors Streetcar Conspiracy
Cable cars are a poor and misleading analogy for interoperability -- that is truly a difficult, one of a kind system, with significant mechanical and switching limitations that don't apply to streetcar systems.

For streetcar systems, by contrast, most cities used the standard PCC car from the mid-30s onward, with minor variations. https://en.m.wikipedia.org/wiki/PCC_streetcar

As for dangerous? During the multi-decade period in question, your link lists two accidents in the US. One is the crash of a gasoline tanker that also destroyed five buildings, which I don't think we can lay at the feet of the streetcar itself.

therealcamino··on Microplastics make their way from the gut to other organs, researchers find
You're asking for studies that show the effects of microplastics in humans. How do you think that gets established? Not all at once. This isn't scaremongering, it is how science happens, part of the pathway to establishing what those effects are. Knowing where microplastics can migrate through mammalian tissues is clearly relevant to your own stated end goal.
therealcamino··on Work begins on a $12B high-speed rail line between Las Vegas and Los Angeles
I was just looking up the LA to SF high speed rail project because the headline sounded so wrong. It's so sad that the official website has a giant photo of their progress: a short section of clean, straight overpass over a country road, with nothing connected to either end, an island of rail infrastructure plonked down in the middle of California. Sigh.

https://hsr.ca.gov/

I know that there are many factors affecting progress, but it's depressing that we can't get to consensus on building infrastructure.

therealcamino··on How Amazon Became the Largest Private EV Charging Operator in the US
> GM on the other hand went the exact opposite direction most of the time and put an overengineered heavy duty transmission with maybe slightly cheaper internals into their smaller vehicles.

Eh, the owners of 80's era Chevy Celebrities/Pontiac 6000s/Oldsmobile Cieras/Buick Centuries might like a word.

therealcamino··on Ask HN: What rabbit hole(s) did you dive into recently?
Is that the one where Jesus sells Thomas into slavery because he didn't go obediently to minister to the people in India?
therealcamino··on Ask HN: What are your go to shell one-liners?
I love this one and use it all the time, especially using the special case when your command can take multiple filename arguments and they come last. xargs will glom as many as it can into a single command before overflowing the max command line size, which can be faster than starting many processes. Grep is the best example:

      find . -name something | xargs grep -C5 search_string
(added the -C5 for context lines)
therealcamino··on Ask HN: What are your go to shell one-liners?

      du -s * | sort -nr | head
to find the largest subdirectories. (Although 'duc ls' is faster if I have it installed and up to date on that machine.)
therealcamino··on "Volkswagen" detects when your tests are being run in a CI server
I'm guessing some share of them are just because they reacted the way I did -- "This name is genius, where can I give it an upvote?" Funniest and most devastating takedown I've seen in a while.
therealcamino··on How engineers at Digital Equipment Corp. saved Ethernet
Yes, the things it's connected to can saturate a 1 Gbps link. But few people feel any pain points that would lead them to want to upgrade. I've only ever saturated mine with speed test sites.
therealcamino··on How engineers at Digital Equipment Corp. saved Ethernet
If you were ever responsible for keeping a thicknet or thinnet Ethernet network running, you would gladly accept that tradeoff. If you've experienced a floor of a building or a whole department go offline because someone removed a terminator, or (this is real) decided to stick the thinnet onto their radio antenna to see if it improved reception, you'd value the increase in reliability a lot more than the extra cost.

There were actually these connectors you could get from AMP that would hide away the thinnet connection behind a wall plate, with proprietary connectors to the machine, just to keep people's hands away from the shared network segment.

therealcamino··on How engineers at Digital Equipment Corp. saved Ethernet
But network-layer bridges were not a tiny step, they were a fundamentally new type of device with many enabling technologies. The point of the article is that it was revolutionary, not incremental.
therealcamino··on Free data transfer out to internet when moving out of AWS
> "safe to read when and only when you already know what's going on / the underlying truth"

I've never read AWS blogs before but that was exactly my feeling after reading the linked article on "fair software principles" or something. You can tell that somebody has a hobby horse they're riding, and it's only because it's in their financial self-interest, but unless you already knew what the actual issue was before you read the blog, you're still going to be clueless afterwards!

therealcamino··on Honda's first US-market EV is here–the 2024 Prologue, driven
Or in this case, since it's mechanically a GM Ultium vehicle (a modification of the Chevy Blazer), it's a prologue to Honda producing their own EV from scratch?

therealcamino··on My business card runs Linux and Ultrix (2022)
Guy: "I wrote a MIPS R3000 emulator from scratch, ran it on a microcontroller on a board I designed myself, and emulated a late-80s DEC workstation well enough to run not just Linux, but also DEC's own proprietary closed-source Unix on it (although I had to patch the Ultrix kernel's machine code, without source code or even symbols in the exec, to fix a bug). For fun."

Internet: "Pssh. Not pretty enough. Next!"

therealcamino··on Microsoft lays off 1,900 Activision Blizzard and Xbox employees
"You listed one career choice and agriculture is actually the easiest industry. #2 lowest failure rate in 1 year, #1 lowest after 5 and after 10 years [1]. What you thought was fucking hard is objectively not compared to every other industry from BLS data. "

You are pretty clearly defining "hard" differently than the poster you're responding to, as somehow being related only to the chance of a venture failing. But obviously that's not what "hard" means when the other examples include being a prisoner of war.

They did not study memory in isolation. All the details are available at the link to the journal article. It doesn't seen fair to accuse them of p-hacking without first understanding what was studied.
therealcamino··on Hans Reiser on ReiserFS deprecation in the Linux kernel
One could imagine a lot of counterfactual things! But that doesn't make them true or plausible. Do people really think it's worthwhile to argue, after he led police to the body, that removing the seat was a camping project? What is the point you are trying to make?
therealcamino··on Black Triangles (2014)
It was used during the 80s.

Like I said, I'm not telling anyone what to do. Everyone can feel free to call anything whatever they want, to use or reuse symbols as they see fit. The signifier is not the signified.

Just wanted people to know. Because like I said, if your goal is to communicate, you might want to know if you're using something that has another, emotionally-loaded interpretation.

therealcamino··on C and C++ Hot-Reload/Live Coding
God, it was so, so convenient. Near instant turnaround time for fixes. It was especially good in combination with 'pop', which returned control to the calling function just before calling the current one. It gave you a sort of limited form of do-over, with the caveat that it didn't try to undo any effects of the called function so far. Or you could just fix and restart.
therealcamino··on First new VAX in 30 years? (2021)
Nobody's sold new VAX systems since the 90s. VMS was ported first to the DEC Alpha architecture, then to Itanium, so even for VMS, VAX is two architectures ago.

And Itanium itself is at the end of the road now, but I think still supported for the moment.

therealcamino··on FAA orders grounding of more than 170 Boeing 737 Max 9s
You are confusing two different issues. The article you reference is from December 2022. The MAX 8 had already returned to service two years prior, with the required fixes to the MCAS system, in 2020.

This law had to do with a deadline for certifying the MAX 7 without completely redesigning some of the systems.

I'm not a Boeing defender here -- these issues are incredibly concerning.

therealcamino··on C and C++ Hot-Reload/Live Coding
> Debuggers might hot-patch code to insert breakpoints, but that's not the same thing as replacing running code.

Solaris dbx did have this capability -- patch and replace code with newly compiled code from your updated source files -- circa 2000. You just typed "fix" and it worked. I've been wishing for that capability on x86 Linux ever since.

therealcamino··on Black Triangles (2014)
Nobody owns it, obviously. It can be helpful however to be aware of the associations your terminology already has.

From a practical perspective, it interferes with getting your point across to overload a symbol that already has strong associations. From a social perspective, it's considerate not to use symbols that have strong negative associations for others (which is not a view shared by the "fuck your feelings" crowd, although I've noticed that they're not all that consistent in that view, and it tends to depend on whose feelings are getting fucked.)
