> how do I know the data on the drive is not corrupted without reading it? Are there best practices to continuously compare the replicas in the background?

I assume you're talking about already-written sectors becoming unreadable or a similar failure. Unfortunately, I don't think you can. This is what I believe the "patrol read" feature of RAID cards is meant to address.

Fortunately, however, I don't believe there's evidence that if the data is readable, it would ever be different from what had been written, so comparison isn't needed. The main exception to this is the case of firmware bugs that return sectors full of all-zeros.

> Does that impact durability of the drives?

I haven't read the studies (from Google, mostly, IIRC) in a while, and I'm not sure if they've released anything lately for more modern drives [1]. However, I believe you'll find an occasional "patrol read" won't noticeably reduce drive life/durability.

[1] Especially for something like SMR, whose tradeoffs would seem particularly attractive for something like this archival-like use case.

Self-driving car bombs?
Are we looking at a future where any hateful person could easily convert a self-driving vehicle into a car bomb? In an America that is becoming increasingly factionalized and hateful, wouldn't this threaten to destabilize society? Should self-driving vehicles be banned? Think about a self-driving tractor-trailer loaded with ammonium nitrate soaked with fuel oil. I am certain there are people in America who would find detonating one attractive. What sort of targets would be attractive to such people? Even a SUV could be devastating.
I haven't watched broadcast TV in years, but I certainly remember quite a bit growing up - maybe rules have tightened? I have no experience with US advertising, but yeah, privatised medicine must lead to issues we don't get.

Which is ironically also how you fixed it. I'll never forget the "magic" of wrapping my Xbox 360 in several towels and overheat for 30 minutes to supposedly resolder it back together. It worked for another 6 months after that until it completely and finally died.

The surface pro seemed designed to be a tablet that could also be your computer. The surface book is a laptop that can also be a tablet. This difference is really important for interaction. That said I feel like the digitizer is only really useful for taking notes that contain diagrams, or things like digital art. I also barely use my surface book, despite thinking it's one of the best alternatives to my beloved 2015 15" MBP.
I haven't used it. Wikipedia explains that it doesn't have (equivalents to) ORDER BY, EXPLAIN, transactions, Skip/Take.

It looks like it's proprietary -- but worse, you can't even run it locally. So you're locked in to a closed source DB service provided by one vendor that is entirely irreproducible outside of that vendor's environment.

That sounds like somewhere it's fallen short to me. What are you supposed to do if you have to leave Azure for some reason? Apparently you can't even access backups without raising a support ticket.
Dave Lee's tests usually come from a gamer and media creator's perspective.

In most, if not all, of his reviews he makes a point to check thermals and throttling related to heat, because that matters to the gaming segment of his audience.

As for media creation, he always tests Adobe Premiere for his cross-platform media creation tests while acknowledging that Premiere on Mac is less performant than it is on Windows, and that there's a significant number of Mac media creators who prefer Final Cut.

The better question to ask is if any of those other sites who did benchmarks did heavy workload testing on the computers for extended periods of time. Running a CPU hot for short bursts can yield different comparative results than for a task that takes 30 minutes or more.
I have a Dell XPS 15 (2017) and the thermals are really bad. I saw constant throttling in my kernel logs and the laptop sometimes slowed to a crawl when compiling, running a ton of docker containers, using Light Table or even just having a ton of browser tabs open.

I finally ditched it a few weeks ago, finally replacing it with a Ryzen 7 desktop.

I'll admit my XPS 15 was a factory refurbished model, so maybe I just got a lemon. It got so hot the battery is now swelling and it popped out the trackpad (I think there might be a recall; or if not take it in since that's gotta be under warranty).

My current laptop is a HP Spectre. It's thicker than the XPS, but I think it's got a much better cooling solution and preforms better. I don't think I'd recommend a Dell XPS again.

On a similar note, I've seen one large client's PCI compliance team tell us that we couldn't use Stripe for their integration, primarily because it's seen as a payment processor for startups and not for the "enterprise." It didn't help that Stripe doesn't give out Merchant IDs. Additional risks have been that Stripe has made breaking changes without an api version update and the number of data issues/edge cases we've run into with automatic reconciliation reports.
Assuming that Christian laws apply to an Islamic country is a strange stereotype.
There are other options. If you have forced induction and direct injection you fix both those problems. You no longer use the crankcase for pressurizing the intake so the bottom end can be lubricated like a 4-stroke engine instead of adding oil to the fuel. With forced induction you can blow clean air through the ports expelling all the exhaust without wasting any fuel.

This obviously adds quite a bit of complexity to the design, though. It may not be economical in the end. And that's assuming you can get it to meet emission regulations.
I've been trying to deploy configuration profiles containing IKEv2 VPN configs to macOS devices through MDM (Meraki SM) without success, even though the exact same profile works fine for iOS devices.

I’ve seen a lot of weird stuff on the road in China, very close to the proverbial kid chasing a ball into the street (though it might be some farmer chasing a goat, pig, or chicken). Anecdotally, I’ve never seen something similar happen in the states.

It just doesn’t happen in the USA, people aren’t prepared for it, which is well enough since the fatality rate is still low. It will happen in China if you spend a few week there.
One unconventional tip for code challenges comes to mind. A candidate used it on me and it was worth a ton of points in my book.

Instead of just doing the challenge ask the interviewer what they want you to optimize for? Performance? Shortness? Readability? Maintainbility? Make it clear there are tradeoffs to each and that the tradeoffs you choose often matter more than the code itself.

As a plus you also get insights into what the company values.

I totally agree. But let's say that I setup an IKEv2 server in pfSense on some VPS. And now I want to connect to that with my macOS VM. There's no Mac server anywhere involved. And Apple Configurator is in fact the only way to configure the macOS client.

Rule 4 regarding unsigned long is a horrible example as Windows keeps them as 32 bits on 32/64 bit compiles while UNIXes vary between 32 and 64 bits depending on compile mode making unsigned long a disaster of portability across platforms and bitnesses.

Stopped reading at that point as this article doesn’t deal with EBCDIC platform portability either... so overlooks the entire IBM main and minicomputer/OS400 market as well. And I say this as one who writes code on all of the above that does Unicode internally but one still has to interface with the OS.

Anyway. There is a LOT more to portability than what is written here.

It probably depends on their infrastructure, e.g. if storage is something like cassandra, records would be evenly distributed by key hash.

My experience with various portable computing devices over the years is that they overheat and shutdown to protect themselves when used in direct sunlight combined with warm to hot ambient air temperatures.

I do not expect the manufacturers to overbuild the thermal capacity such that this isn't a problem, not when we're talking about portable devices which (appreciably) prioritize compactness and lightness.

In the past I would have to shade my laptop while using it to play MP3s from the passenger seat with the convertible top down while on road trips through Nevada, to prevent if from overheating in the direct sunlight. It never crossed my mind that this was some kind of failure on IBM's part, the machine was already pushing the limits of what was possible at the time in the interests of being small and light.

If a datacenter boasts flawless durability for 19 years and loses everything in the 20th year, then they have an infinite number of 9's for the first 19 years and zero for the 20th year. It's all about probability.

Nobody can promise 100%, but that doesn't mean that all those 9's are meaningless. They mean a lot for budgeting, and even more for insurance purposes -- which is exactly what we as a civilization have come up with as a way to amortize loss in the event of a local catastrophe. Your premiums are going to be much higher if you don't have enough 9's in a critical part of your money-making infrastructure.

No one here is saying that you don't need geographical redundancy. First we need to figure out how many 9's we can realistically expect in order to determine how much redundancy makes financial sense.

China has an amazing history, but has been rife with war and tumult. It has not been a continuous well run autocratic state for 6000 years. Take the Han dynasty:

After 92 AD, the palace eunuchs increasingly involved themselves in court politics, engaging in violent power struggles between the various consort clans of the empresses and empresses dowager, causing the Han's ultimate downfall. Imperial authority was also seriously challenged by large Daoist religious societies which instigated the Yellow Turban Rebellion and the Five Pecks of Rice Rebellion. Following the death of Emperor Ling (r. 168–189 AD), the palace eunuchs suffered wholesale massacre by military officers, allowing members of the aristocracy and military governors to become warlords and divide the empire. When Cao Pi, King of Wei, usurped the throne from Emperor Xian, the Han dynasty would eventually collapse and ceased to exist.
Doctors have to wrestle with insurance companies as much as you do.
+1. Obviously not every drug can be self-prescribed, and not every condition can be self-diagnosed.

Remember when you needed to go to a doctor to get a prescription for Fexofenadine or one of the many other antihistamines? Seems ridiculous in retrospect. We should limit ourselves to a year, maybe two at most, of prescription-required status for new drugs that should be over-the-counter, and only to get some experience (data). Some drugs should require a new N-year prescription every N years as patient conditions might change requiring examination.

Uh, wow, at no point have I made the claim that an electrical circuit is not a quantum system. Nor have I claimed that they are incapable of simulating quantum phenomena. Quite the very opposite.

What I did clearly state, and insist as quite relevant, is that entanglement and double slit experiments are hocus pocus and irrelevant distractions. In fact, I stated that this experiment says basically nothing because it merely simulates quantum phenomena within a circuit.

Hello? Yes. Electrons are quantum entities, and assuredly interact with photons which are also quantum entities. This is demonstrated by the photo-electric effect, which we can all notice by placing tin foil in a microwave. Therefore a circuit is indeed a quantum system, since it assuredly deals in electrons.

Wow! Didn't even need to publish a paper about qubits to draw that conclusion! Amazing!

The implication here is that Bell is waste of time, and so is his theorum: such that emission doesn't determine state, especially when you don't look at it.

Pattern recognition with DNA-based neural networks
I disagree that 3D printers are only for prototyping. I work on making useful robotics hardware that people can make on cheap printers. I think if you design for 3D printing you can develop some really useful hardware that people can make anywhere in the world. Ultra low cost injection molding as you described would be great, but that technology doesn’t exist. Meanwhile 3D printers can make custom parts more easily than before. This changes the way open source impacts the world. We’re already surrounded by open source software, but perhaps in ten or twenty years time we’ll be surrounded by open source hardware as well.

Xiaomi Mi 8 SE with High End Specs – Full Specifications
Uh, it turbos in the 4+Ghz range. That is by itself probably going to blow the 45W thermal rating the entire chip has. My gut instinct says that macbook probably can't even dissipate that over a long period of time. The linked test seems to indicate the truth of that, and its not unusual for a mac product, the last one that could probably continuously dissipate the combined cpu+gpu heat was that crazy ugly mac pro.

Intel didn't invent some new physics to get "high" performance cores crammed into a laptop, they are just pulling the same stuff the phone market has been doing for the past few years. Put enough thermal capacitance against the chip itself to absorb a few multiples of the chips dissipation, allow it to get really hot, and then throttle it hard. Hope, people keep their benchmark runs short.

There is a difference between socket 2011/2270 based i7/i9s and their insufficiently cooled, memory and IO bandwidth starved cousins found in laptops. Even a fairly low end desktop is going to stomp the most expensive laptop you can find simply due to physics. Being able to dissipate more heat means higher performance. Its possible to move the curve up/down depending on fab processes, or micro-arch, but these days there aren't any miracle cures. More power equals more performance.
