>Bit twiddling integers doesn't require unsafe type punning like this.

Not only that but, at least for Fast Inverse Square Root, it's not advantageous to carry out the bit twiddling since the rsqrtss instruction is faster and more precise, and vectorized instructions are faster still for large strings of floats.
Another way of looking at it: those telling us that we must lockdown seem to not even try to think about it from any perspective other than simply saving lives, regardless of consequences.

Every year my confidence and trust in politicians and any expert with a role in setting policies gets lower.

First off, we should be clear what we mean by "guarantee". When you're talking about Rust, "guarantee" means "the compiler enforces this in an ironclad way, such that the programmer cannot mess it up" (generally with the implied caveat that we assume unsafe is not used). C++ programmers generally use "guarantee" to mean "the standard says you should follow these rules", because as the language is not type-safe the compiler is in general unable to enforce much of anything that is interesting, making the Rust sense of the word "guarantee" not a particularly useful concept in that language. Confusion between these two meanings of "guarantee" (along with related concepts like "safe") has resulted in a lot of misunderstandings over the years.

Bearing this in mind, neither concepts in C++ nor traits in Rust guarantee any semantics in the Rust sense of the word. In the C++ sense of the word, C++ concepts do carry guarantees, in that the spec says what they should do. But, in this sense, so does Rust: PartialEq [1], for example, has semantic requirements spelled out in the documentation. In my mind, the difference is that Rust programmers tend to program defensively, not trusting programmers to get things right that the compiler doesn't enforce. Thus you see a lot of conversations along the lines of "what if the implementer of trait X does something weird?" in the Rust space. This may give the impression that Rust traits don't have a clear and consistent semantics associated with them. But that's not right: the implementer of PartialOrd, for example, is absolutely expected to implement a proper partial order, as explained in the documentation. A specification for Rust could specify associated semantics for those traits, just like in C++.

Maybe I'm uninformed, but the nazi/vaccine correlation I've seen have been likening being told that one should get vaccinated is similar to the holocaust.
Right. Not only that, in my experience, TVs and monitors really don’t even support specific rates - what I mean is, they can usually accept a range of timings. It would probably require extra work to intentionally _not_ support some specific rates.

They might report support for specific rates in their EDID, but you can usually feed it almost totally arbitrary video timings and it will still work as long as your vblank, front porch, etc. values are somewhat reasonable and you don’t exceed its max rate.

Furthermore, if you were to send a display a video signal with timing parameters for 24 Hz but actually clocked at 23.9, I doubt the monitor would even care. After all, it must tolerate some frequency difference since the incoming signal is being clocked by the sending device.

The only time I’ve ever seen a display (in this case, an LG 4K monitor) act weird is when I fed it an interlaced signal.
Taxing vehicle volume without regard to other factors unfairly penalizes families and carpoolers.
From the article:

> In his book, however, Binet depicts the conquering Incas as far more benevolent than their European counterparts. Atahualpa becomes known as “the Protector of the Poor” for his egalitarian policies. The Incas are horrified by the savagery of the Spanish Inquisition, in spite of their own traditions of human sacrifice.

From the Wikipedia article on Atahualpa

> The Cusquenian nobles named Huáscar (another son of Huayna) as Sapa Inca, and he appointed his brother Atahualpa as governor of Quito. The Inca Civil War began in 1529 when Huáscar declared war on Atahualpa, for fear that he would try to carry out a coup d'état against him. Atahualpa became Inca emperor in May 1532 after he had defeated and imprisoned Huáscar and massacred any pretenders to the throne. The Spaniard Francisco Pizarro captured Atahualpa in November 1532 and used him to control the Inca Empire. While imprisoned by the Spaniards, Atahualpa gave orders to kill Huáscar in Jauja, thinking Huáscar would use the Spaniards as allies to regain his throne.

The thing you're still missing is that the ruling was that the @RealDonaldTrump account was being used in an official government capacity, and therefore would fall under said government specific regulations.

If you look at the actual ruling[0], you'll see that on page 9-11 of the ruling, they outline ways in which the @RealDonaldTrump account was used in an official capacity, and on pages 42 and 43, they outline how this is governmental control of the account (but not of twitter as a whole).

Quoting the ruling:

> First, to potentially qualify as a forum, the space in
question must be owned or controlled by the government...Here, the government-control prong of the analysis is met. Though Twitter is a...company that is not government-owned, the President and Scavino nonetheless exercise control over various aspects of the @realDonaldTrump account...The President and Scavino’s control over the @realDonaldTrump account is also governmental...the President presents the
@realDonaldTrump account as being a presidential account as
opposed to a personal account and, more importantly, uses the account to take actions that can be taken only by the President as President

So please, stop crying "misinformation" when you're just wrong about the legalities of the situation. You may disagree with the ruling, but my description of it is factual.

This reminds me of an observation whose name escapes my feeble attempts to Google, that roughly states government bureaucracies tend to find more things to grow into over time, rather than diminish.

Wish I could find what it was… I remember reading about it in the context that if you wanted to grow your underdeveloped country, you should do as western countries did 50-100 years ago, rather than copying current institutions, as doing the latter would likely keep you from being competitive.
If you're packing values into NaNs it's easy to end up using all the bits. For example, if you start storing 48 bit pointers you only have 4 bits plus the sign bit left over for the type of the value.
That's awesome! Seeing how wholly dependent modern manufacturing is on CNC makes me respect those early machine operators even more. They were constantly innovating on how to apply physical geometry and minimize incremental errors in order to build parts with tolerances that would still hold up today.
Not necessarily. High pressure electrolysis tends to be very efficient, and gets you over the hump of getting to 200 bar with only around 3% energy loss. Compression energy is logarithmic, so getting to 700 bar from that point takes less than half the energy that we would have spent getting it 200 bar. Figures I've seen have it at around 6-8% energy lost to get to 600-700 bar (the last part is done on gas, which is less efficient).

That said, if we really wanted to, we could do deepwater electrolysis and let the Earth do the compression for us. You wouldn't even need oceanic electricity generation, because there's enough of a pressure differential between the surface and, say, 2km depth, that you could comfortably siphon some of the pressure in a turbine to power the reaction. The limitations at this point are mostly engineering and manufacturing -- we know how to do electrolysis at those pressures, and we can even do salt water electrolysis.
Haven't tried the latest versions of WinFsp + SSHFS-Win, glad to see a new GUI for the later and new versions. My experience is good but if you have an unstable connection, the mapped drive didn't reconnect by itself at all times. For a better experience I've always relied on RaiDrive (free with Ads) or SFTP Drive from N software (free for non-commercial)
Finally, proof that my dog is a genius! And not just the usual confirmation bias, because she really likes to walk.
This makes absolutely no sense to me. Every great walkable neighborhood built before the mid twentieth century (in other words 99.9% of them) have no HOA.

As a matter of fact, I wound say the exact opposite. The HOA is more likely going to keep out the bars, cafes, restaurants, and groceries that actually make a neighborhood walkable.

Pounds That Kill: The External Costs of Vehicle Weight

Heavier vehicles are safer for their own occupants but more hazardous for other vehicles. Simple theory thus suggests that an unregulated vehicle fleet is inefficiently heavy. Using three separate identification strategies we show that, controlling for own-vehicle weight, being hit by a vehicle that is 1000 pounds heavier generates a 40–50% increase in fatality risk. These results imply a total accident-related externality that exceeds the estimated social cost of US carbon emissions and is equivalent to a gas tax of $0.97 per gallon ($136 billion annually). We consider two policies for internalizing this external cost, a weight-varying mileage tax and a gas tax, and find that they are similar for most vehicles. The findings suggest that European gas taxes may be much closer to optimal levels than the US gas tax.

Commercial vans like the Ford E-150 are large, but actually have very good visibility, much better than cars. This is due to the sloping nose, and the big fat side mirrors.

It makes sense, as business drivers using those vans often need to get in and out of tight spaces.

They were talking about larger vehicles blocking the visibility of people in smaller vehicles. Visibility of pedestrians by someone in a large vehicle is not really an issue (it's a small blind spot that one should be tracking objects/people as they move in/out of it, just like for the other blind spots).
Not to poop all over this article but doesn't the advance in automotive industry also bring things like automatic brakes etc to protect against collisions, lane swerve etc. :/

Many HDMI devices will display a very wide range of inputs. A group I hang with are exploring all that with a micro able to output native HDMI / DVI. It has been enlightening.

The industry support at the display level is good and can be even better.

This really is all about streaming having to compete with a body of legacy media. To a lesser degree it is about the most efficient solutions between creators and distributors.

The Xbox problem mentioned can be fixed with a firmware update. So do that... sheesh!
Yes indeed. We weren’t talking about car insurance, where prices are (at least somewhat) based on risks.
Won't be possible with ESNI, and regardless you could just use an inconspicuous domain name, for example by piggybacking on a common cloud service.
Sending a stream of conscious email to a friend can make sense early in the creative process. Publishing it in way that presents it as a finished product may end of wasting a lot of folks time.

Candidly I took away only one useful observation from your essay: all organizations are teaching organizations. They teach "the way things work around here."

I will engage in a discussion if you first take another hour to make your thesis and points clear. Don't publish it, send the draft to the coordinates in my profile.
If you don't support what Apple did here, lobby your government representatives to pass the proposed "Open App Markets Act" [1].

It explicitly outlaws companies with App Stores that have more than 50 million users in the United States (eg Apple, Google) from self-preferencing in App Store search, among other similar restrictions [2][3].

X-ray producing synchrotrons are generally pretty large and expensive. There has been thoughts of using them for lithography and microfabrication in the past (see LIGA) that haven't really panned out. There are companies working on more advanced laboratory sources, but mostly for analytical applications (EasyXAFS, Sigray). There is a company working on a lab scale synchrotron (lyncean tech).
Are they any software companies that follow this advice? Can we name them? Are they more successful than the rest? Are their developers happier, or paid more?

Unless I'm terribly confused, we spend a lot of time on this topic, but the companies that exhibit this behavior seem to be just fine, if not wildly successful.
Ah good point, I like that idea, especially as it utilizes that infrastructure and doesn't make them disappear when there's a transition to electric.
Australia sacrificed international travel too. It still leaked in which led to occasional limited lockdowns. Until Delta strain hit and spread too fast for the small lockdown strategy to contain it.

Australia screwed up the vaccination strategy. They bought AstraZeneca and relied on a domestic vaccine that was being developed which failed in trials.

Then the AZ side effects became an issue and there was no backup plan.

But even the AZ rollout was a debacle with no one sure if they were eligible or how to get it. And the Prime Minster excusing it all by saying "it's not a race".

If Australia had the vaccination rate of the US or the UK (which was absolutely achievable) then Australia would still be the envy of the world.
One thing that is beyond vexing is that politics comprises both policy and tribal allegiance. I have no interest in the latter but it seems impossible to discuss policy without tribalism crashing the party.
How is that even relevant? You are just changing the subject.

I'm sure truely authoritarian societies have professional engineering societies with ethics and rules about who can call themselves what.

How does your point relate to protection against state surveillance?
"I think you are describing a different phenomenon: Large sedans getting replaced by other vehicle types leaving smaller sedans."

Basically, but it's also that the meaning of the terms have changed. The Caprice is and was a full size car. Today's full size car has about the same capacities and room as an older midsize car.
How do you know the Linux kernel you are running that verified compiler on isn't subverting the compiler? The only way to do bootstrapping sanely is to start from some manually written machine code (not assembler) and eventually reach Linux/GCC/etc. This is the approach being taken by Bootstrappable Builds.
I think you'd attract/retain more users if you added a way to demo the game without having to login/register (despite the fact that the registration is quick and easy), and then prompting them register after completing one or two quests.

In my experience, people turn away as soon as they see the a registration form if they haven't had a chance to play first (or unless the game is already very popular). Do you have any analytics running on your site to track the bounce rate?
Clever design, perhaps. However, it only applies to small, residential AC. Commercial systems use more efficient designs already, such as screw compressors. Also, good luck using this with a turbine - many of the largest compressors directly driven by gas or steam turbines, which are way more efficient than electric motors because they eliminate inefficiencies associated with electric generation and distribution.

You appear to be confused, or conflating this with something else. None of that describes the system Apple has implemented for iMessage. If the child doesn't want the adult to see anything, that's a choice available to the child.
Engineer, from wikipedia:

> Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost.[1][2]

I think it's just kind of silly to try to title something based on the how, not the what. A painter paints, right? But what about all of the other jobs and roles that include painting? Are they painters?

Those that disagree with "Software engineers" being called "Engineers" are again propagating nonsense (my post that started this thread).
> Anti lockdown people will not change their opinion even if there are proof that masks mandate and lockdowns works

Even if they do work it's barely relevant to the argument that lockdowns should be avoided. Lockdowns would have to work and be less harmful overall than cutting off or reducing access to everything else people depend on in society, like schooling, mental health services, cancer diagnostics and treatment, and so on and so forth. That's a tall order.

Anti-lockdown people who claim lockdowns don't work are surely employing motivated reasoning.

Only 6200 per year? Reducing this by maybe a few hundred does not seem like a productive thing to spend political energy on. I question if it would be utilitarian even ignoring the political cost. That’s really far down the cause of death list.
For some features, like autosaving and cloud sync, sure. Others like doing things in bulk, macros, plugins, not seeing ads, control over updates, all that stuff is vanishing.
Vapor compression is a technology ripe for disruption. I reckon the IP holder knows this and is trying to monetize this while they can.

I think tech based on magnetocaloric cooling is one option. There was a company I was following a years ago (I've since forgotten the name) that was researching advanced thermoelectric cooling technologies that would be offer much better performance than peltiers.
Fairly certain humans have been breaking rules almost as long as we’ve been making them.

It is. Motors that can regen also 'cog' if you're out of power, which sucks. It turns out it's a lot more comfortable to just have a freewheel system that can coast without any extra friction. The extra energy recoverable otherwise just isn't worth the tradeoff.
Wow. There are about 14k to 19k homicides per year in the US. I think there should be at least 1 geofence warrant per homicide. I can't imagine anyone would find that controversial, to just see what devices were in the vicinity of a homicide around the time it happened. But it per these numbers, investigators are dropping the ball on at least thousands of homicide investigations.

I regularly watch this channel and I honestly believe his claims of independence (no revenue from any kind of sponsorships or adverts, just from Patreons). I think he simply want to be helpful for his audience and forward questions/responses if he has the chance to do so.

Overall I like his content, he is usually fairly technical and realistic about the prospect of things he cover. He has also has done some deep dives in e.g how to calculate levelized cost of energy to help analyse/compare different new inovations he showcase on the channel.

But sometimes I guess it can be slightly too pop-sciencey, reminding me (both in a good and bad way) of the glossy science magazines of my youth. Extrapolating barley lab bench-viable results to full scale production, with very optimistic timelines etc.
I agree with you that poor software engineering has ops implications, having supported trashy production apps with appalling memory leaks. However, I don't believe that knowing ops necessarily makes you a 'better' software engineer — the beneficiary here is not the software industry (or said software engineer), but your employer specifically, because they now get to hire one person who will do everything. The same goes for the rise of the fullstack developer, who god forbid should get paid a dime more than a backend engineer.

I'm advocating for the controversial idea that people should get paid more if they are capable of (and doing) more.

I don't think your article itself is very novel or controversial (i.e., it's good old regular stuff), so I'm steering the direction of the discussion towards something I find more interesting.
I moved back last year in the middle of the pandemic.

Honestly, life in Japan is much more relaxed for me. I’m not as competitive, not as wrapped up in being successful. That’s a very individual thing, but that disconnect was my favorite thing. I know I was an outsider and I was fine with that.
Financial Times is pretty good, and definitely not liberal.
From the article:
"Drawing more people into cities could help significantly shrink the country’s overall greenhouse gas emissions. Low-density developments produced nearly four times the greenhouse gas emissions of high-density alternatives, with research finding that doubling urban density can reduce carbon pollution from household travel by nearly half and residential energy use by more than a third."

This refers to the overall volume of pollution, but not the concentration of pollution in a particular location. If you're from the UK you've likely heard about Ella Adoo-Kissi-Debrah, who tragically died aged nine in 2013 after an asthma attack. Last year a coroner's verdict was given stating pollution played a part in her death, specifically the high levels of nitrogen dioxide. I know this is just one case, but it makes me think the fine structure of urban planning is very important in this respect.
My truck does not have those sensors, and it is still large. When driving through downtown, kids and people like to jump out from between parked cars. That’s hard enough to catch in a sedan. I could definitely see myself accidentally hitting a pedestrian and not even noticing it.

I would say yes, you need to see things immediately in front of you. I’m not sure how that’s even a question. Beeps and sensors don’t save you in busy pedestrian environments, and being aware of your surroundings is absolutely crucial.
