The Dell R7525 chassis is available with dual 800w power supplies. General thinking for power supplies is that each power supply is connected to completely separate power distribution - independent cabling, battery backup, generators, and points of entry to the facility. In many cases it's also two different power grids. This is so that if one power source fails anywhere the load can move over to the other power supply without exceeding the power that can be delivered through a single power supply or trip a breaker anywhere. Under normal operating conditions each power supply is doing half the load.

Additionally, the National Electric Code in the US specifies that continuous load should not exceed 80% of given circuit/breaker capacity.

So with dual 800 power supplies at "max" 80% load that's "only" 640 watts for one of these 2U servers. For 208V power that's only 3 amps. High density (for sure) compared to the old days but not as ridiculous as it may seem.
Uh, why are you linking a lot of NY times and random letters. You are aware that news media often misunderstands science or gets it wrong by amplifying the most surprising and interesting conclusions one might take from research?

This whole "they told us the world is cooling" thing is an almost completely US-only phenomenon.
Okay sure I guess, but what is this meant to imply? Even taking it at face value, this clearly still didn't cause Europe to call that war the first World War, so what conclusion are we drawing from this?
This list is too much.
One can take inspiration from the list but ultimately you want answer to your own questions you have for the recruiters/companies.

If I recruited someone and they'd ask me all these questions I would look elsewhere.

There's a problem with GitHub lists that accept PRs. They accumulate over time. Almost nothing is removed. No one wants to remove someone else's contribution.

This list needs heavy editing, and some form of feedback mechanism by which those questions that perform best are weighted higher.
Btw, this was a challenge for me when started this project. Is it better to have a .com or country specific domains and/or potentially different names. Should I use the same code base or different ones. Same server instance, etc. I had a name I really liked in French so I kept it and created https://videmongrenier.fr/ and decided to use a more generic name for worldwide (http://shopmystuff.com/). Same code base.
It lists KVM as an option in the very first part of Chapter 2 under the synopsis.

The Monumental Molasses Morass of 1919
This is a big part of the problem. I was a child in the 70's and 80's, and it was a constant drumbeat about how climate change was going to freeze the planet.

It was rather hard to take it seriously when the narrative suddenly shifted to how climate change was going to melt the planet.

I never hear discussion about the discrepancy, so the whole thing has been quite a head-scratcher!
In an app I'm using postMessage and JS injection to communicate between our in-house HTML/CSS content (due to what we're building, we had and still have many legitimate reasons to code that way) to seamlessly integrate the native side and the dynamic HTML views.

Any change would be a huge nightmare for apps like ours, potentially impacting many other apps as well.

I wish government legislature did this with their bills. Reading a piece of legislation is maddening because it's always just a description of diffs, without seeing the final outcome.

I never really realized that this symptom was common with RFCs as well.

Is there something about how governing bodies work that lead to this style of output? Why aren't we using a bit more modern techniques now, more akin to how word processors let you see the diffs inline but also the final format? Or git-style PRs that show the deltas but you can always just view "main"?

M2 is not limited to 8GB. 8GB is only the base Macbook Air M2 model. You can buy one with 16 or 24GB. Most people who buy 8GB Macs these days complain about performance, while people with 16GB praise it.

Could you elaborate on what you mean by "heavy"? React Native Web produces a pretty normal React app, it's not that different from what Ionic puts out.

But if hybrid performance is sufficient for you, both will probably be fine.

I would say; pick one and start building! You could even try out both. That will give you much more insight than trying to reason about it.

I think nuclear power is great and would go a long way to solving our energy needs, so I'm not sure how that's relevant. Moreover, the soviets stopped existing in 1992, so their influence 30 years later is limited.

Im not sure if there’s a good way to use css to animate an arbitrary number of children with a delay, while retaining clean markup. I did this before:
.article-child {
animation-delay: var(—index)*0.025s;
}
and while rendering, set style tags on each element style=“—index:5”, etc. That works, but it was annoying to maintain, and every single element has these style tags. So I just use Motion One (WAAPI) now.

If the story of concern is the Salon article about Christian homeschooling, my gut wouldn't consider it "necessary for HN's health" because my gut leads me to believe that the intersection of fundamentalist Christian homeschoolers and HN'ers is small (though it almost certainly exists) and therefore the article is unlikely to cause changes in child rearing techniques.

That leaves it mostly in the preaching to the choir category at best and an attractive nuisance for commentators in the average case.

> - A lot of code paths are fully dependent on hardware that can't be mocked. How would you test the bootloader, for example? Or code that depends on a certain processor architecture? The only way is to actually run the code on that hardware.

My incorrect assumption was that one could run those tests in some sort of a virtualised environment where the host VM provides the tested component with the correct virtual hardware. The "hardware" itself contains mocks the test can access to run assertions. In other words, testing would involve checking the side effects. Come to think of it, that doesn't sound very practical. In fact, it sounds almost impossible to scale.
Most of the blogspam on the Internet today are website filled with product 'reviews' and affiliate links. These aren't derivative of anything, so they won't be downgraded. Neither will the hordes of blogs breathlessly reporting celebrity and business gossip. A search engine won't be able to differentiate between the quality of a TMZ vs say Variety.
TDD is another tool in the toolbox. It has it's place, and combined with good tooling, can make for a great development experience. I use it mostly when adding features to an existing code base. In C#, with modern tooling like Visual Studio, Rider, or ReSharper, you can use your test as a base to start scaffolding methods out with auto generated code, and that can end up being a time saver.

For a brand new product, I'm almost never using TDD. I'm building out a solution in the pattern I want, getting some minimal feature or features up, and then I write tests appropriate to that pattern. Later on I might use TDD to keep working on it, but it can be a burden at the start of projects.

Not to mention, if the emulation isn't 100% accurate, you could still run into something odd. Especially if you only emulate what's in the spec and not the actual hardware.

This is the natural end result of committee-style work - because if you work on a "diff" you can force the discussion to only touch some small parts of the whole, but if you work on an "updated document", even if everyone kind of agrees the only change necessary is to Section 7, the fact that the whole document is "up for discussion" causes the whole thing to be up for discussion.

In both cases they can still produce the "final document" which the government is often better at than standards bodies.
I wonder about the bouncing, because I often either (1) check out a couple more results, only to find that they aren’t better than the first acceptable one, or (2) open the first ten or so promising search result in new tabs in one go before looking at the actual pages. Google can only make limited inferences about result quality from that, meaning that its ratings become skewed toward less sophisticated users.

I think there's a split in the industry; outside of FAANG senior means "certain amount of time spent in front of the computer getting paid", inside FAANG, it's a set of behaviors encapsulated in a particular mid-career job title.
Yep, that's completely fair. In fact, I'm pretty sure that's the setup described by @QuinnyPig with a Pi-hole in their home lab and all devices meshed together via Tailscale (so WireGuard really).

I have a bit of latency reaching my home lab when I'm traveling, hence my approach with Fly.io.

There's also the appeal of having a single self-contained Docker image solving a specific problem. I'm quite adverse to running critical services, or anything that I can't redeploy trivially, so overall I'd rather pay a bit of money for the peace of mind that a PaaS offers.
If there are solutions that don't involve authoritarian communism, I'm all ears. Encouraging nuclear seems like a really good idea.

As close to the eyeballs as possible. With OpenConnect[0] they are located in ISP facilities and/or carrier-neutral facilities with access to a peering fabric (kind of the same thing as the OpenConnect Appliance is "hosted" by the ISP).

It's a win-win. ISPs don't have to use their peering and/or transit bandwidth to upstream peers and users get a much better experience with lower latency, higher reliability, less opportunity for packet loss, etc.

I'd say that's true of almost every real world example normally discussed. It is quite common for "buyers" to put multiple candidates on ice for as long they can possibly leverage to do so while they evaluate their options, be it in dating, hiring, or purchasing.

I'd ask "Why do you need meaning?". Why not just accept that life is meaningless, and any meaning you bring to it is ultimately of your own construction. Seems a lot simpler than continually searching for meaning or purpose, doomed never to find it because it simply does not exist. All evidence seems to indicate that we're complex meat robots, whose existence is basically inevitable given the right initial conditions. What meaning?
I enjoyed reading your blog post. It was very well written. Most of your points resonate with me.

It exists. E.g. on macOS it’d actually use the AMX matrix multiplication units (for benchmarks that use BLAS) and blow away most x86_64 CPUs that have to rely on AVX2.

Did they go ballistic when Google introduced the Panda update in 2010, killing many of the the web-scraped, machine-generated blogspam that was poisoning search results? No, they moved on to fresh territory like Youtube, gaming the recommendation engines. And they eventually came back to the web to poison results with hordes of awful 'best bicycle for fitness in 2022' type afilliate marketing sites.

Nadir Crater Suggests Second Impact After Chicxulub Wiped Out Dinosaurs
A lot of the reasons they've had to build most of this stuff themselfs is because they decided for some reason to use freeBSD.

The NUMA work they did, I remember being in a meeting with them as a Linux Developer at Intel at the time. They bought NVMe drives or were saying they were going to buy NVMe drives from Intel which got them access to "on the ground" kernel developers and CPU people from Intel. Instead of talking about NVMe they spent the entire meeting asking us about howt the Linux kernel handles NUMA and corner cases around memory and scheudling. If I recall correctly I think they asked if we could help them upstream BSD code for NVMe and NUMA. I think in that meeting there was even some L9 or super high up NUMA CPU guy from Hillsborough they some how convinced to join.

The conversation and technical discussion was quite fun, but it was sort of funny to us at the time they were having to do all this work on the BSD kernel that was solved years ago for linux.

Technical debt I guess.

People keep forgetting how science works when it's convenient for them to do so. In the 70s Time reported scientists concerned with global cooling. Yes, some scientists were concerned about global cooling, but there was no scientific consensus. It was a scientific discussion. Now of course people say "scientists said" something back then and "scientists are saying something different" today - you just can't trust those darned scientists! Which of course simply isn't true but even if it were - so what? The evidence is the evidence.

Nonsense.

It's still impressive. A 5x increase at that scale can be a phenomenal challenge. Where do you source the ingredients? Where do you build the factories (plural because at that scale you almost certainly have multiple locations in different geographic locales subject to different regulatory structures). Where do you hire the people? How do you manage it? What about the storage and shipping and maintenance of all the equipment and on and on? How much do you do in house how much do you outsource to partners? What happens when a partner goes belly up or can't meet your ever increasing needs?

Your comment is a great example of what the OP pointed out.

It's not about the number of homes on the market, it's about how many homes you want to look at total (which is capped by the number of homes on the market). So, you say that you want to look at 10 homes max. You take 37% of either quantity as the evaluation period. After the evaluation period (3.7 houses) you commit to the first house that's better than the best you saw in the evaluation set.

I got down to "k" too. What about "x" and "y"? One important consideration of nested loops is row major access pattern rather than column major pattern, so access array[i][j] rather than array[j][i] due to the data locality of each. You shall get a performance boost by accessing them in that order.

I worked on parallelizing nested loops across OS threads and load balancing between outer loops for different progressions through the loop. I also wrote some code to reverse the loop direction to avoid a cache miss when the indexes go back to 0.

If only there was a single standard for webhook subscription verification. Cloud services invent their own authentication protocols. Webhook verification in Dropbox is different from that in Trello.

Great engineering but how does this 800Gb/s throughput achieved translate downstream all the way to the consumers? I suspect there may be switches and routers from ISPs and others that Netflix do not control in between that will reduce the effective throughout to the end user.
No real mention of why. So, why?
More ram = more performance if there's a cost in going across a bridge to keep the pipeline full. 16gb of _unified_ RAM that can be accessed by the CPU and GPU without a performance hit in going to the motherboard is a factor in some workloads. Whether you agree or not, it's an effective test comparing two architectures.

So the question is: are you spec benchmarking, or are you interested in the performance of the workload, because it's the actual work that matters, not how the bits are stored under the keyboard.
