Reordering I/O operations matters a lot for hard drives because seek times depend on where the head is and how far it has to travel.

The effects in play for SSDs are very different. Reads are more likely to be performance-critical than writes, so it can be beneficial to limit the number of write operations that are in the drive's queue so that reads can be serviced more quickly. Writes take longer than reads, but they can usually be deferred without causing problems (though the Optane SSD in question doesn't have a write buffer). Deferring operations also sometimes gives the drive the opportunity to combine more host commands into a single media access.

The order of commands issued to a SSD matters much less than the number of currently pending commands. If you're issuing just reads or just writes, there's little benefit to reordering them unless they have different priority levels (which NVMe allows through the creation of separate queues for each priority level, but I don't think Linux currently uses this).
So to clarify a bit...maximum/emergency braking like this is not limited by regen or by the hydraulic brakes. It is limited by tires, grip, and weight transfer.

You got a good mate, mate.
Depending upon your statistical sources, US traffic fatalities are around 1.25-1.50 per 100 million miles. [1] All forms of real-world autonomous driving across all manufacturers across the world are still somewhere below 200 million miles, conservatively estimated. [2] [3] Between the Tesla and Uber fatalities, by these rough back-of-the-envelope numbers, autonomous of various grades is still roughly 2X higher than human drivers. Maybe 1X if you squint at the numbers hard enough, but likely not orders of magnitude lower. I don't anticipate rapid legislative and insurance liability protections for autonomous systems until we see orders of magnitude differences on a per 100 million miles driven basis, and that will take time.

Waymo racks up about 10,000 miles per day across about 600 vehicles spread in about 25 cities. [4] Roughly 3.6 million miles per year if they stay level, but they're anticipated to rapidly add more vehicles to their fleet. In the US alone, about 3.22 trillion miles were driven in 2016. [5] Don't know what a statistically valid sample size is based upon that (I get nonsensical results below 2000 miles, so I'm doing something stupid), though. If Waymo puts two orders of magnitude more cars out there, they'll still "only" rack up about 365 million miles per year, and not all the miles on the same version of software.

Don't look at GDPR and see it as some kind of slap in the face to Facebook or Google. The reality is that regulation like this invariably benefit the companies large enough to hire the lawyers to abide by the regulation. Similar story for tax-law complexity.

Large corporations thrive in highly regulated environments without fear of competition.

It doesn't cost anything more than the colonoscopy. It's required by the ACA to be included in a colonoscopy.
Steve Jobs studied Eastern Mysticism and Calligraphy in college. It was the calligraphy class in particular that informed his ideas about design.
The submission title is strongly misleading. From the page:

Unlike most other programming languages that encapsulate the
build system, package dependency manager, and project
dependency manager into a single tool (such as Rust's cargo
or Go's go), build2 is a hierarchy of several tools that
you will be using directly and which together with your
version control system (VCS) will constitute the core
of your project management toolset.
100% on the same boat as the opening statment, but he lost me at "systemd".
Your statement makes it sound like the GDPR applies to individuals doing everyday activities (or draws an equivalence). Just for clarity, I looked it up and it doesn’t appear to:

“This Regulation does not apply to the processing of personal data: (...) by a natural person in the course of a purely personal or household activity;"

So, it really only applies to companies, or if you’re processing a large amount of user data for a hobby project.

That being the case, it doesn’t feel like the bar to being able to respect the law is so very high. But I’d be interested in counter examples.
That's currently limited by Intel; Apple wont put high power DIMMS into Macbooks;

Intel do not suport LP-DDR4 > 16G right now, Although that's expected to change soon.

I have a Kaby-Lake Dell laptop which has full power DDR4 because I wanted 32G, but it costs in battery life.
The comparison for NYC is a solar hot water heater system which provides ~100f hot water and cost around 3k. You don't directly save on cooling costs, but as heating costs dominate and you get much warmer hot water that's worth it.

Relative net savings depend on getting a system sized for your use, and how much cooling you use in the summer. But, you can also add solar panels for summer use with the overall value balancing over the year.
To expand on your first and last points:

Your researcher got a result. Great. What is their objective evidence that the result is real rather than an artifact of a bug in their code? If the code is garbage, you can't trust the result, no matter how much of a breakthrough the result would be if true.

That doesn't mean that the code needs to be production-ready. It does mean that the code needs to be clean enough to be trustworthy. (Tests can be included in this evaluation.)

If the code's going to be product-ized... maybe ask the researcher which parts of the code they think are the most troublesome. Start by re-writing those pieces, from scratch, with production levels of rigor. Then, as other parts prove troublesome, rewrite those too. Don't band-aid them, rewrite them. Keep the interfaces, unless the interface itself is part of the problem.

I don’t know why people are still surprised by this. There are a lot of people in powerful places that want Bitcoin to fail and die. Futures markets introduced a regulated way for them to make that happen.

Buy up a ton of Bitcoin during the lead up to futures trading, then short Bitcoin on the futures market while market selling thousands of the cheaply acquired Bitcoin on spot exchanges. You succeed in lowering the price of Bitcoin, killing the public’s perception of crypto currencies, scaring away retail investors, and you make a killing in the process.

JPMorgan has been using futures markets to manipulate Gold and Silver spot prices for years while also accumulating huge amounts.

First, the company decides whether the request needs to be complied with or not, and if the user doesn't like that decision, they can complain to the regulators who may choose whether the refusal is worth looking into.
I have a B.A. in History (Pre-industrial Europe and Far East, and post-WWII American Foreign Policy) degree from UC Davis, and I ended up full-stack programming for the last 12 years.

I use those History skills daily from writing documentation, synthesizing concepts into a coherent work, and figuring out the intent of the original coder.

My History degree is definitely not useless.

Sure. Compile at -O0.

A huge number of seemingly-trivial optimizations depend on assuming that undefined behavior will never happen. The number of optimizations that don't depend on UB in any way is quite small. For example, if you want to get pedantic about it, even automatic promotion of local variables to registers is exploiting undefined behavior—who's to say you didn't have a pointer that just happened to point to one of them?

Yes, although if we're talking about improvements in RAM density (lithography improvements) rather than just putting more equivalent RAM in a machine, then that tends to mean lower power consumption per bit.

not having officially recognized responsibilities

I feel like that's a bit of an overstatement. While scrum advocates for shared responsibility, it doesn't demand no-titles, no-roles, or no-passions.

It's all about ensuring the entire team possesses 'T' shaped skills. Depth and expertise in some areas, but still generally knowledgable across all areas. My test engineer doesn't write much code, but in a pinch, she can. My PO is fully capable of "running" the team in my absence, as is the test engineer. All my developers know the full DevOps pipeline and can contribute to it, though none of them are DevOps engineers by title or primary responsibility. And I'm an ex-developer-now-manager who can do a bit of everything, though these days I'd rather go to meetings and play office politics so my developers can do their thing.
Your full regression test suite needs to be 100% automated and fast enough to execute within a couple days. If you don't have that then you have a bigger problem that goes beyond any particular development methodology.

A proper Scrum definition of done requires full test automation for every user story. You can't merge code to the release branch or accept the user story until all the automated tests (unit, functional, integration, system, performance, etc) are working.

My understanding of colleges is that they tend to accept pretty much anyone if they aren't coming straight from high-school. The idea is that people who have lived in the Real World™ who choose to go to college understand why an education is important and will naturally work hard for their degree (because they see it as one of their last chances to escape from whatever situation lead to them applying), whereas high-schoolers only want to go because they've been told they have to in order to be successful.

Obviously this isn't true for true Ivy-league schools, but it does tend apply even to larger state schools, such as the ones in this article.

A deep dive into PostgreSQL streaming replication
My thoughts on AGI (at least in the sense of being indistinguishable from interaction with a human) are the same as my thoughts on extraterrestrial life: I'll believe it only when I see it (or at least when provided with proof that the mechanism is understood). This extrapolation on a sample size of one is something I don't understand. How is the fact that machine learning can do specific stuff better than humans different in principle than the fact that a hand calculator can do some specific stuff better than humans? On what evidence can we extrapolate from this to AGI?

We haven't found life outside this planet, and we haven't created life in a lab, therefore n=1 for assessing probability of life outside earth (which means we can't calculate a probability for this yet). Likewise, we haven't created anything remotely like animal intelligence (let alone human) and we have no good theory regarding how it works, so n=1 for existing forms of general intelligence.

Note that I'm not saying there can be no extraterrestrial life or that we will never develop AGI, just that I haven't seen any evidence at this point in time that any opinions for or against their possibility are anything more than baseless speculation.

I find such reasoning to be bullshit.

Example: DuckDuckGo had no issues in ensuring people’s privacy for years and I’m fairly sure that they have zero problems with GDPR. And they are not and have never been at Google’s scale.

What happens actually is that privacy-violating companies are trying to keep doing whatever it was they were doing, but then discovering that no sane individual would opt-in to being tracked, without having access blocked of course, which then leads to lost revenue anyway.

So they are trying to game the system, which gets expensive of course. Now you need lawyers and experts in dark patterns. But when your entire business model depends on people's ignorance, you really can't claim the high moral ground.

Such articles are engaging in sponsored FUD.
This. Walmart's image has been severely tarnished over the years as a result of their abusive labor practices. Now that Amazon is also acquiring that same image, it's the perfect time for Walmart to pull a PR about face.

I suppose they hope such a gesture will woo people away from Amazon and back to Walmart who cares about people, unlike Amazon.
I'm curious if you've ever worked with something like cargo or go build. CMake works well for what it does, but it doesn't do the right things if you've ever seen more modern solutions to the same problem.

Have you considered that USA Today doesn't have an exquisite understanding of the law?

Or perhaps, that USA Today is collecting tracking data on its users and selling it secretly to 3rd parties and doesn't want to stop spying?

Plenty of other newspapers have had no problem implementing GDPR. It's as simple as not spying on your users.

But all told, the path to making it popular would be to make it part of new construction. I understand why they want to try to make retrofitting cheap, but it's just not even close right now.
Amen. IMO the root of all evil is compiler "optimization" of code. If you really, really need the wee bit of extra performance through optimization, hire an expert at ass'y language and optimize the bit that matters. Rarely is this the case, especially with business apps.

I've seen my fair share of bugs from the compiler incorrectly hoisting variables from loops, mis-using registers, etc. I prefer to turn off compiler optimization as one of the first steps in a new project, but that's me.

I think they are overselling Google's contributions a bit. It was more "Web 2.0" that shook Microsoft's dominance in tech. Google was a big curator and pushed state-of-the-art. Google was built on a large network of commodity hardware, they were able to do that because of the Open Source Software. Microsoft licensing would have been prohibitive to such innovation. There was some reenforcement that helped Linux gain momentum in other domains like Mobile and Desktop. Googled helped curate "Web 2.0" with developments / acquisitions like Maps and Gmail. When more of your life was spent on the web, the operating system meant less and that's also why Apple was able to make strides with their platforms. People weren't giving up as much when they switched to Mac as they would have previously.

Microsoft was previously the gatekeeper to almost every interaction with software (roughly 1992 - 2002). I don't know of good books on it but Tim O'Reilly wrote quite a bit about Web 2.0.
That's the thing, though -- it doesn't scale like that. If a 100-person company has a DPO, you can't have someone who spends 20% of their time as a DPO in a 20-person company, because just keeping up with what you need to know takes a large amount of time.

Official sources, especially law enforcement, have a habit of loaded claims with regards to everything. There is always an agenda, some propaganda, someone "bad", something "bad" happening to scare people and so on, with pretty much no verifiable information. But even if for some miracle it is verifiable, why would media ever report on any of that, when there are a lot more deaths from other causes, all barely reported and a lot more other issues. Obviously government propaganda somehow has priority in mainstream media over any actual issues societies face.

Reading this headline I was reminded of the cyberpunk dystopia where corporations own their employees. By colleges costing more than an individual can afford and corporations paying for an individual's education, you get a system whereby individuals become effectively indentured servants paying off education debt to their employer (there are already government jobs where this is basically the way it goes). Student loans are predatory but at least let you change employers in theory, but if you're indebted to a specific corporation then things are potentially even more dire (unless you have other means to buy your way out).

But on the other hand, I can't blame Walmart or any other non-education company for high tuition and I think it's good they give employees the opportunities to get a practical college education.
