The full C++ execution core is intentionally not published yet. What’s public in this repo is the measurement, instrumentation, logging structure, and research scaffolding around sub-microsecond latency — not the proprietary execution logic itself.
I should have stated that more explicitly up front.
The goal of the public material is to show how latency is measured, verified, and replayed, rather than to ship a complete trading engine. I’m happy to discuss methodology or share deeper details privately with interested engineers.
My reasoning behind the pidfd thing would just be as a way to try to avoid race conditions, though on second thought maybe it's not needed. I think you can take your pick on how exactly to validate the executable. My thought was to go (using /proc/.../exe) check that the file is root owned (and in a root owned directory structure) and then use its absolute path as a key. Seems like it would be a decent start that would get you somewhere on any OS.
I think it would also be feasible to add code signatures if we wanted to, though this would add additional challenges.

At today's prices perhaps, but pre ChatGPT you just have to run more of it + more error correction. Not great for the power budget but not anything significant in the grand scheme of things.
It's literally not a single solution. systemd isn't a piece of software, it's, like, 20 pieces of software.
People who think the init system is doing all of this have just not done even the bare minimum amount of research on the topic. Although, granted, the naming might not help.
Simulation. It takes a lot of effort totday to bring up simulations in various fields. 3 D programming is very nontrivial and asset development is extremely expensive. If I have a workspace i can take a photo of and just use it to generate a 3d scene I can then use it in simulations to test ideas out. This is particularly useful in robotics and industrial automation already.
What will make development sustainable? I mean it could take some time until it gets trackson and also usually open source works if there is a supporting company behind it.
That’s pretty cool, and I just checked the prices and it only starts at 11k dearer than the standard f150, which is less than I expected. Interesting.
What’s more insane to me as an Australian is its 50k USD starting price in America, but in Australia it starts at $149k USD as they’re only sold by third parties that do right hand drive conversions (at imo a way too high premium, 100k for that service + shipping???)
I rented a mach-e recently. Went up to Snoqualamie pass from seattle. I used over 60 miles range in 10 miles on the steep part at the end, 1/6th. Going the other way I got a maybe 20% boost in distance over flat. There were a few places I was able to regen-brake, but I never had the battery go up, only stay flat. And a few times I lost enough speed that I didn't handle an interim flat well. I was extremely disappointed.
It turns out friction and drag are still things. On a pure downhill you would be able to roll, but it's not as good as going down is bad.
I also found that the car did a lot worse rolling down hill than my mini-cooper manual when I just put the clutch in, which got up to hairy speeds. Heck vehicle seemed to have more inbuilt resistance to just rolling than the fire engine I've run down that hill.
The only benefit as I perceive it re: orbital data center hardware is regulatory avoidance. Think...DDOS machines that can't be shut off; or financial hosting services for unsavory individuals. However, it's very expensive by all metrics (including those talked about in the article), and frankly, these satellites are sitting ducks for the hunter killer satellites the various space powers have, if they actually wanted to do something about these hypothtical data centers and the problems they would cause.
They did it this way: from the powerplant, it was hot steam under pressure, not even water, that got to the block-sized heat exchanger (serving maybe 500-1000 people, 200-300 flats - one large soviet-style block or 2-3 smaller ones). There, heat exchanger warmed the technical (indeed totally non-potable, almost poisonous, and constantly circulating) water for the heaters, that was only there during the heating season, and separately, tap water, these were two completely different, non-mixing circuits (and both of them short without much insulation - maybe around 100 meters each way outside, plus within the buildings). And sure the tap water wasn't potable, but it had nothing to do with the way it was heated - there were two completely different circuits for hot and cold water anyway, cold water never entered the heat exchanger building. It was always a separate building by the way, i think because a potential accident with high pressure steam could kill a lot of people if it happened right within the residential building itself.
We were told that hot tap water was totally dangerous to drink and no one tried to. Cold water was unsafe to drink but some people either had reverse osmosis filters, which i know aren't good because they deprive water of a lot of useful stuff too, but no one knew it back then, or they boiled it, but most just drank it as it was. Shorter lifespans and much lower average age, and plenty of other life dangers like mass alcoholism, made water quality was a lot less important than it is today in the West - it won't be water that kills you anyway, it's vodka, lifestyle, of the Party itself.
I remember my first encounter with Matlab. Some YouTuber was building a toy rocket and he was simulating it in Matlab (Simulink). He just put in the weight of the rocket and it gave him the trajectory, apogee, flight time etc. It was like magic to a beginner like me.
You can do the same thing in other languages but it won't be built in like that.
Go to the army for five minutes and you’ll find 10 different ideas of products to create. Your failure is based on your limited and narrow perception, not the lack of ideas of things to create
I imagine a world sometimes where punitive measures reflect the scope of crimes. If steal from a person is 1 year, then stealing from 1000 is 10 years and from a million is a lifetime. That’d put the end to political shenanigans, in my imagination.
Not only have you undermined your claim to a Nobel award by showing a spurious understanding of biology, you wrote, quite sarcastically "it is impossible for humanity to discover new information that updates our world model". Well then, we will all await your discovery of that 3rd gamete, or some theory so innovative that it tips this well studied, well understood, uncontested (by any valid competitor) model to the wayside and humanity can revel in this new information, the better model of reality that you promise.
While you're at it, you could tell us all what the scientific discovery was that made gender separate from sex, who found it and when, and what the defining difference is. Did they win a Nobel for that?
I request that in any reply, you refrain from spamming me with Wikipedia links to articles you don't understand and probably haven't read.
I guess you could strap a few kw generator in the bed with some jerry cans as backup. Would take longer, but if by loiter time you mean time out in the field where you’re not moving, then maybe that’d work. Would be cool if there was the equivalent of siphoning gas from one to another.
Is there electric infrastructure in the places you’re describing? If so, should be really easy to throw down some moderate-speed L2 chargers in various parts as a last resort. They’re incredibly cheap and don’t need much maintenance.
F150 has a 130kWh battery, so heating is not an issue. Height changes are also not a problem. There are very few areas with large altitude changes, and even fewer ones that you'll likely need to pass through regularly.
This leaves mostly mountain passes around the Sierra mountains. And by some strange coincidence, they have plenty of superchargers in the vicinity.
The rest of the country can be, to the first order, considered flat. E.g. elevation change between Charlotte and Charleston is mere 300 meters.
Commenting to provide a confirming data point. I bought a Kobo Libra H2O a few years ago. Unboxed it, modified the config, and immediately started using it with Calibre. It has never participated in any manufacturer's "ecosystem" and has functioned well in a totally "offline" capacity.
I was sad to hear newer Kobo devices are shipping with Secure Boot. I've never reflashed my Libra H2O (it's my daughter's and I'd never be able to get it away from her long enough to replace it) but I liked knowing that I owned the device. I'm sad to hear the new ones are owner-hostile.
It’s nothing to do with politics, it’s just maths. And if you think I’m a leftist, you would also be wrong!
Unfortunately, educating yourself on this topic is not easy and involves differential equations. The economic models that fail to predict our current situation are simplifications. I’d link you, but I don’t think I’ll be getting a very receptive audience!
One of the great American stylists, he nevertheless managed to write sex scenes that were unbearably cringe-making. The meticulous, magical gift for poetic physical description that led him (for instance) to describe a snowfall at night as "an immense whispering" was misapplied to the mysteries of sex. A year before his death in 2009, the British magazine Literary Review, famous for its annual Bad Sex in Fiction competition, simply threw up its hands and gave him a Lifetime Achievement Award.
And yet it would be a mistake to call him the horniest writer of his time. It was quite a time.

Appreciate the pushback — it’s valid.
