Something like 30-50% of all human genetic variants are shared across continents. It's hardly asinine to say that a significant proportion of genetic variation is shared with everyone. Depending where you are talking about, ~20% of variation is unique to a given continent.

I don't think PCA plots really tell us much beyond there being distinct genetic clusters? One could do a PCA only on people with european ancestry, or people living in a small town, and there would be plenty of interesting structure to look at.

That was fun. Thank you for sharing.
It's incredibly lazy to say my criticism was "just lazy" since I didn't post criticism but answered a question about the contents of the article.
Absolutely batch and use asynchronous completion. All modern systems (NFSv4, GPUs, NVMe, etc) uses a variation of the theme. However, one should also work on lowering the context switch cost.

Another notion that I find interesting is one-address space. You still get per process protection, but address space is global. Supporting virtual memory is extremely expensive (we are paying the price today with hardware table walkers, multi-level caching of translations, various flushing on context switches). It is much cheaper if we only have to implement permissions (there are many options here) and it can make zero-copy process communication much cheaper.

Also, if you are giving up on paging, we can move beyond the 4096 byte page which we got with the 1962 Atlas (it had the equivalent of 96 KiB total memory; if pages had kept that ratio we would be using ~ 8 GiB pages today).
I’m getting irritated with how common it is for every service organization to now prompt for tips when paying electronically. A Venti plain Starbucks coffee is over $4 now. I’m sorry, I’m not tipping for that.
By the way for anyone curious how the numbers in the article compare to a modern desktop computer, a 13th-generation Intel Core does 169ns/url, twice as fast as either of these server rigs. If I cap mine to 3GHz to reflect more realistic server scenarios, 310ns/url, a bit quicker than the Graviton 3. Even the "efficiency cores" on a desktop are faster than these server parts, at 286ns/url.
LLVM languages can all natively link with C code, since any LLVM bytecode can directly call other LLVM bytecode. So Zig, C++, Obj-C, Swift and Rust can all be compiled together.

But C compatibility is everywhere. Almost every language has a FFI (foreign function interface) for C code. C interop shows up in every language because at the end of the day every language needs to be able to talk to the operating system. For example, to read and write files your language needs to call functions in libc (or equivalent). And that library is written in C.

So, Nodejs can call C via has native modules & NAPI. Java can call C through JNI. Ruby has the ffi gem. Python, Luajit, Go, C#, ... the list goes on. They all have a mechanism to call C code.

If you're looking for another language that can live alongside your C code, you can choose any.
My main mission is to make Nix and Nix-based technology mainstream. Please reach out if you are interested, have thoughts or ideas. (plus we're hiring: https://floxdev.com/careers )

This involves improving Nix itself, as well as building tooling for teams and organizations to be successful.
I am speaking strictly in regards to the human system of sending away children to become clergyman, which is a way of dealing with future inheritance problems regardless the sexual fitness of a given child.

That is to say, the family picks a would-be inheritor and sends away all the others to hopefully prevent family feuds.

I do not speak for mice and their culture, whatever it may be.

Mail fleet work 8am-6pm they have 14 hours to charge they don't need to charge all at once in 1-2 hours
Not too long ago, myself and many other long time employees left our startup after a SPAC announcement. As an individual contributor, I kind of felt insulted that I was expected to not really get what was happening. Upper management put on a celebration and equated it to an IPO.

If they had come out and said, “we are out of money and options, so this is what we’re doing”, I might have been more inclined to stay.

It sometimes amazes me the kind of obtuse missteps so called “business people” will make. They effectively drained all their experienced engineers in one fell swoop.

Expect that the people you want to keep are paying attention, and you’re not going to pull a fast one on them. Seems pretty simple to me.
Many post offices have parking lots where the vehicles park overnight currently. Mail carriers don't take these vehicles home, they typically park on USPS property overnight. I suspect this is the top candidate location for many of these chargers.

FWIW places like 18F are frequently hiring engineers, product people, and designers, the pay is similar, the work is related, and they are 100% remote.
And what? Give up personal mobility? Without cars/trucks, rural life stops. Good luck buying food in the cities if in the country farmers have to walk everywhere. EVs are not practical in our winters. The batteries would simply not survive without constant heating, which would defeat any carbon advantages they might have.

And as for fuel delivery, cars are not everything. Trucks/boats/aircraft together consume vast quantities of fuels. They arent going away anytime soon. So the infrastructure will remain a while too.
how do you see Nix being affected or not by newer package management systems with built-in sandboxing and layering, such as OCI container images on the server side or flatpak on the desktop side?
I have an aging Huawei tablet, wondering what 10" non-locked down tablets are available these days (at decent price)?

I wonder what the functionality of that big nose is. I doubt it's all for a crumple zone. That and the flat front windscreen certainly aren't a problem for aerodynamics at the low speeds at which these typically operate.

Looks like something out of a kids movie though, which is kinda neat actually.
I think there's a few assumptions here that apply to households, but not purpose built business vehicles.

1. They may not be typical chargers. Connecting multiple vehicles to the same source which can distribute the power based on time and need may be possible in this case.

2. If these are purpose built, we don't know if charging the vehicles even applies. Totally made up idea: batteries easy to replace get shipped off for charging off-site and cycled daily. (+ single on-site charger for emergencies)

3. You're not charging 10 EVs immediately - you have 10 EVs which need power at the beginning of the next business day.
> Also please limit whatever your equivalent of root to deny and delete.

So what creates/specifies user contexts, loads drivers, and installs kernel updates?
> electricity prices per mile of transport per ton were about 25% that of fossil fuel prices per mile of transport per ton

In shipping and logistics, time is money. Fuel can be dispensed in the US at a maximum of 10 gal/minute. Factor that against the largest charger you can find and see why the single cost difference doesn't matter yet.

> They should really move all long-haul trucking to electric as well

Reduced capacity from doing this requires additional vehicle time to haul the same amount of material. This isn't a single factor equation. Plus, over the road drivers sleep in their vehicles, and not always at truck stops. They're only allowed to drive for 10 hours, so it's not always as convenient as you might expect.

Consider the weight of 600 gallons of fuel vs. the reduced hauling capacity from using an electric truck and see why we're a ways away from this yet. Have no fear; though, the moment this is logistically favorable, they will switch.
Newtonian physics is still good enough and used every single day. "Civilizations that collapsed without leaving substantial legacy" are footnotes in academic papers: fascinating and useful if you're in the tiny number of people in the field of research, not so much otherwise. Not the same thing at all.
Yeah, but now you've gotta build a better AI that can go "that's a rock, you dummy" to the million or two false positives.
That’s a valid concern too. For a lot of static sites I visit, I don’t particularly care if people know I visit them as I live a boring life. My primary concern is malware and verifying identity.
People high in hierarchical world belief see the world as full of differences that matter [..] You might imagine that, to them, the world looks full of big, bold black lines. The opposite view—held by people low in this belief—tends to perceive differences as superficial and even silly. For individuals with this perspective, the world is mostly dotted lines or shades of gray.

This conflates two distinct things: the belief that things differ (e.g. blue is different from red), and the belief that there are clear and unambiguous distinctions between categories (on the color spectrum, where exactly does blue transition to red?)

It seems one side argues there is a clear, objective line between blue and red, while the other argues blue and red are the same color.

What would stop you from buying your vendors products? Choice & freedom seems to present no negative, doesnt impede your scaremongering safety-clutching Stockholm Syndrome desires.
Based in that means "being intoxicated with cocaine".
Yes, but, the actual math matters. There are a lot of banal public infrastructure projects that cost much more than the value they create, and there are also theoretically productive public investments that are double-dipping into the same “surplus value.” To illustrate there are many roads that were built in hopes of spurring development and development never occurred, but the roads are maintained anyway at a substantial loss of taxes. And to make a simple hypothetical as you did, suppose the train subsidy creates some surplus, but then the city also runs a bus and a ferry and installs bike lanes all on the same route and all of these are gloriously uncrowded… at this point we’ve probably eaten up all the surplus value and then some.

This is hopefully obvious, and yet the excess road building problem is ubiquitous in the US and costing us fortunes.[1]

So we can’t just hand-wave and suggest that all infrastructure and all subsidies always create more value than they cost, we have to be critical and especially careful not to pretend that non-financial benefits can pay for real financial costs.

The better solution is to host an internal package repository. It's pretty easy to package up a vendor library and publish it there.
"They plan to buy more EVs" can (again, I expect) probably be safely read to include "and the requisite infrastructure to accompany them" eventually.
There is so little need for a post office any more except as a junk mail delivery system. I'd rather see phase out plans.
HTTPS improves security even for a static site because it prevents an ISP or middleman from injecting ads (or worse) into the page.

It also increases privacy because the contents of the traffic can not be observed by third parties.

I'm not sure how popular these are, so I guess if the explanation included that fact it'd be even better!
The problem isn't the good times, the problem is when something happens in the middle of the night, when a RAM stick goes bad or when you suddenly need triple the compute power. Usually, you get to feel the pain when you need it the least.

I'm hosting a lot of stuff myself on my own hardware, so I do sympathize with this argument, but in a time>>money situation, going to the cloud makes a lot of sense.

Hey HN! I am a Software Engineer with about 2 years of experience developing for both a startup and large MNC. Have developed full-stack applications from Database to Backend to Frontend, and also got my AWS certified cloud practitioner as I'm seeking to deepen my skills in Cloud Technologies. Came from a non-technical background as a business analyst so great with collaborating across technical and non-technical folks :) Had to take on some Product Manager responsibilities while developing so no stranger to product development.

I am seeking a fullstack/backend role in early-mid stage startups which will allow me to apply my skills and deepen my expertise in backend/cloud, while helping to scale a company aiming to be a disruptive force for good in the industry that it is in.

To see what I can build, please have a look at a startup that I co-founded: https://www.carfixsg.co
Either port to a processor you have or build a RISC-V core yourself, say, with an FPGA. There is an abundance of designs you can use, but actually making a simple core that can support this isn't hard if you aren't too ambitious with the performance.

(I know of at least one RISC-V core implemented with 74-series TTL chips and a vacuum-tube implementation is surely in the works somewhere).
The economics of long haul trucking make electrification hard.

Fortunately, for local deliveries like the post office, constant stop-and-go means that regen braking can really stretch the range of electric batteries.
My neighborhood delivers the mail on foot, while the truck is parked most of the day. The delivery man walks more than a Pacific Crest Trail thru-hiker.

A new mechanism called SBAT (https://github.com/rhboot/shim/blob/main/SBAT.md) is now used to allow revocation of groups of bootloaders rather than individual hashes in order to mitigate the resource consumption
I don't want to pile on, but security vulnerabilities are often composed of a series of seemingly insignificant weaknesses that get chained together in highly clever ways. Anything that is accessed over http gives a potential attacker the ability to monitor activity, MitM, spread misinformation, and find potential other footholds that can be composed into a larger attack.

Just curious, but are you on the spectrum? Or an ESL speaker?

Context makes it clear which claim they were asking for.

In any case, I'm not providing a source. This is a somewhat commonly known thing, and I was speaking from personal experience. If you're still really unsure where I grew up, you can probably figure it out from my other comments.

Feel free to search for whatever you find sufficient to corroborate my claims, or continue to be skeptical (as you should). I don't mind either way.
Exactly one year ago I announced Socket (https://news.ycombinator.com/item?id=30515090), a simple, developer-friendly GitHub App that protects your JavaScript apps from software supply chain attacks. Since then, thousands of organizations have adopted Socket – including Vercel, Brave, BBC, Expo, Storybook, Replit, Metamask – and many more.

Today, I am incredibly excited to announce that Socket now supports Python!

Python is one of the most popular programming languages in the world, with millions of developers using it for everything from data science to web development. However, like all open source software, Python packages are vulnerable to supply chain attacks.

Most "vulnerability scanning" tools merely look up the packages you're using to see if any vulnerabilities have been reported to public CVE databases, an approach that is noisy and riddled with false positives.

Socket takes an entirely new approach. Socket uses "deep package inspection" to peel back the layers of a dependency and characterize its actual behavior. This allows us to detect and block likely supply chain attacks before they strike, mitigating the worst consequences.

With Socket, you don't have to worry about alert fatigue or wasting time sifting through piles of meaningless alerts. By default, Socket only alerts you on the most critical security issues – potential supply chain attacks, known malware, typosquats, and other similarly severe issues.

This means you can focus on what matters most – building great software – while Socket takes care of the security side of things.
Let me know if you have questions and I'll be happy to answer them.
I can believe this, for my brain has also optimized similarly. Perhaps, I have evolved? (JK)
Also, they stop and go constantly, so I would imagine regenerative braking could do a lot of heavy lifting here.
There are a lot of remote areas that only the USPS will deliver to because they aren't profit motivated.
The whole point of the fire tablet series is as cheap as possible while still being decent. The tech specs are always a bit behind, but its been consistently under $200(significantly under when on sale). Practically disposable at that price point.

There is no Name Brand competition in their space. You can go far more expensive for higher end other known brands, or no name tablets with garbage software and no app support.

Multiplying a large enough matrix in Python using MKL for Numpy, I can watch the cpu usage go to 400% in top. You may need to run it in a loop or make the matrices quite large, a surprisingly large amount of computation has to happen before it’ll show up in top.

We'll need decades to install a system that could solve this problem when given weeks of notice. Perhaps those decades of effort will start soon?

Alternatively, if we knew a particular asteroid would threaten us in one decade, that one decade might be enough to do something about it. Many asteroids won't give us that sort of notice, since orbits can have century-long periods.

> In shipping and logistics, time is money. Fuel can be dispensed in the US at a maximum of 10 gal/minute. Factor that against the largest charger you can find and see why the single cost difference doesn't matter yet.

If the time wasted charging/refueling is super valuable you can fix this by provisioning a few more vehicles than there are drivers, or having hot swappable pre-charged batteries and provisioning a few more of those than there are vehicles. Then your recharging/refueling time drops down to a couple of minutes max because you're either swapping batteries out or hopping in a different truck.
Which they did. For decades horses shared the road with cars, still do in many areas. Even today they are not totally banned. Henry ford built a better product. He wasnt out there trying to make the old products illegal.
It is possible that the train lines can be built in insufficiently dense areas to make it worth using, and it can be possible that the roads are designed too wide/too numerous/etc.

Just because a government builds it does not mean it is worth it for society. And if it was worth it at time X, it does not mean it will be worth it at time X+1.
