> [the Z80's] instruction set reminded me too much of the idiotic intel 80x86 family

That is because the z80 was a (mostly) binary compatible superset of the 8080 instruction set, and the 8086 (while not binary compatible) was intentionally modeled after the 8080 such that there was a program that could take an 8080 program and do the 1:1 instruction mapping from 8080 to 8086 and get a working 8086 program.

> I wonder if it would be possible to retrofit an MMU onto a Z80 design

Zilog made a number of Z80 follow-on CPUs, and some have MMUs. It is amazing how far they took the instruction set; the Z80380 could run Z80 code as-is, but it also extended instructions to support 32b operations and had a mode with a flat 32b linear address space. I don't recall ever hearing any consumer product using it though.
> Studies have shown that the ideal daily dosage of coffee is about six to eight 8oz cups, ideally consumed prior to 2pm so that it doesn't disturb your sleep.

I think this claim should have been backed up with a source for the studies that are suggesting people should drink 6-8 cups of coffee each day.

Seems crazy to me! I personally don't drink coffee because I've seen lots of people develop dependency/addiction, even though I'm sure it's not too serious.
The real issue is that gas is too cheap in the US. Everywhere else, except oil rich middle east, gas is expensive enough to discourage people from driving everywhere. They end up taking public transport. In US driving almost always comes out cheaper unless the distance is too great to be convenient to drive.
Agreed. I didn't immediately like OS X when I switched to it from Linux at home (and eventually Windows at work), but once I got the right set of 3rd party utilities (tiling app, keyboard shortcut modifiers, launcher, UNIX package manager, etc), it was a great fit.

I think it'd be difficult to get the keyboard shortcut mappings I have working even in Linux -- Emacs-style keyboard shortcuts everywhere without interfering with the more typical keyboard shortcuts.

Another thing is that if I really need something from Linux or Windows, I can either run a VM, boot into one of those OSes natively, or remote desktop to a server with good remote desktop performance. Hackintosh's are a possibility though have their rough edges, and macOS runs better in a VM these days from what I hear, but macOS is my preferred host OS anyway for things like audio/music production apps and video editing, so I'd want to run macOS natively over other OS's anyway. For the stuff I currently do, Linux and Windows run fine in a VM.

So, going with the original analogy, macOS is like a hotel where you can have your own house inside.
Twin-engine aircraft have only one working engine if one fails, and there are rules regarding how far they can be from the nearest suitable airport in that case.

In practice that means that each type of twin-engine aircraft has a limit: Can only be that far from shore. For aircraft with more reliable engines the limit is higher, so they don't have to pick island-hopping routes when crossing oceans.
Relying on those people to sort out recyclables is probably a net-negative for the environment since they very often leave non-recyclables (or those without deposits) scattered on the ground where they get washed down storm drains, blown away, etc.

It would be better to directly employ those people at sorting facilities, but that can be difficult for a number of reasons.
If the amount will still be a nickel, so that it only applies to the poor and the mathematically challenged, then I'd still call that vestigial.
Most descriptions of the changes don't go into nearly enough detail. Even pilots have a very abbreviated understanding of everything that's going on, using rules of thumb that gloss over nuance in calculating the stability of an aircraft. Probably a lot of aircraft engineers don't have a full understanding in general unless they're forced to "do the math" on a particular plane.

Making the engine more powerful (as is the case here) means there will likely be more pitching up moment (turning about the aerodynamic centre or AC) due to the position of the engine relative to the AC. Speaking of which, there is an AC, an aerodynamic centre that is separate from the center of gravity. It represents the point about which the plane pitchs up/down when a force is exerted on it.

Not only is the engine more powerful, but the different position it was placed in (forward primarily) would also create a different force about the AC, and change the forces the other parts apply to the plane (by moving the AC and CG).

There might have been more to it but even a few months after really diving into this the details are getting fuzzy... plane stability dynamics can vary greatly.
Can this clickbait title be fixed? This is a news article covering a review. The review suggests that the (small) cognitive effects of caffeine and other things present in chocolate have mechanisms that are starting to be understood, in rodents.

Because it's a review it provides no new evidence unlike the implication in the title. Instead, it's suggesting possible neural pathways for why the cognitive effects might exist.

If you like your job, call yourself a programmer and build stuff you like. This article is marginally good advice for your pocket but bad for your soul. Don't be a programmer and act like a lawyer. It's one of the few jobs where it doesnt matter if you 're a dog. You create value, easily, you don't just extract it. It's part of the reason why i m a programmer and not an e.g. academic.
Wifi passwords are typed all the time if you have any friends that come over. And typing randomly generated special characters on a mobile device is especially awful.
The other part of the equation is that retraining are a complete failure. The idea you can teach a truck driver or a coal miner to code is a fallacy.

Retaining programs have a 0-15% success rate. It’s basically useless. What happens is that middle aged people get their jobs automated away and they are left with nothing. Look at what happened after manufacturing jobs left the Midwest. This is the bigger problem is that large swathes of the population will have no viable jobs after automation.
Yes, not unique to boeing, ive seen it in many places.
I'm an extrovert, and I am also interested in "science" and "technology" (but not startups). One of my primary hobbies is very math-heavy, and involves hours and sometimes days of intense focus. I also gave talks in the past, e.g. on functional programming.

The point is, I have no idea how any of this is related to being introvert or extrovert (and was wondering the same in the post you replied to).

People can shut themselves into their room with only oscilloscopes and MATLAB as company on one weekend, and meet up with friends on the next one.

I'm probably not the target audience so take my comments with a grain of salt:

- the landing page is very busy (visually noisy?) with simultaneously moving elements that distract from each other

- I had no idea that 'popout' icon at the top would open a video window

- highlighted words on the page don't link or directly associate with more detailed sections (e.g. media actors, components, etc.

I suppose the lack of details may be intentional to force downloads before you can find out if it might be useful to you. Even one high-res non-animated zoom-able image might have been more useful to me.

Good luck with your product.
We don't have good public transit in LA, much less to Bakersfield. But even if the train went all the way to Union Station in Los Angeles, you'd still need to rent a car to get anywhere useful, or take Uber/Lyft. And same thing on the other end.

Have you used LA rail recently? It's a lot more functional than it used to be: https://en.wikipedia.org/wiki/Los_Angeles_Metro_Rail although it still has a ways to go.
On my own I could only translate the word on the left, “狗官”. The first character means “dog”, the second one means “officer” (that one is the same as in “警官”, which means “police officer”).

> You're assuming everyone grew up in a middle class neighborhood with good teachers and was never pressured by gangs and never mistreated by authority.

I'm not assuming that at all, I just don't buy it as an excuse for anything. Should we let such problems fester forever? Aww, gee, this kid grew up around gangs, guess we better give him a free pass for a few crimes that we wouldn't give to a privileged kid?

If anything we need to be harsher on gangland so as to eventually stomp it out. Unless you think that we should just accept organized crime as a fact of life and stop trying? Damn, those Brazilian favelas are looking better all the time, eh?

Amazon - often picks all the suppliers, and lets the buyer decide which they prefer.

Also - they deal in finished (consumer) goods. There is a whole lot of coordination before that stuff gets assembled and ready for Amazon or one or their marketplace suppliers to ship it.

Maybe they've integrated the demand chain logistics, but not the integration supply chain. And they don't dictate that consumers get to purchase one and only one brand of whatever product (like peanut butter).

> And no, you can't be "a little bit of both".

This is absolutely untrue.

Extroversion - Introversion is a spectrum and people can exist anywhere along it.

From personal experience, I am an introvert. I recharge from time alone or with a very small group of good, close friends and colleagues. Regardless, I was developer evangelist #3 for Twilio (circa 2011-2013) covering literally all of North America at some point where a major part of my job was to speak in front of large groups regularly (spoke at 15+ confs/year, no clue how many user groups) and spend every spare moment trying to understand every person, project, and community I came across. I can thrive and get recharged (much more slowly!) from that too. I've continued similar things at Okta for the last 3 years.

After most of those trips - I found 3 days is my threshold - yes, I need to stop and be back among that small group/alone to recharge. But those quiet times alone are when I came up with the best solutions to the ugliest problems and helped me do my job.. and many others do their own better.

Like anything, it's a balance.. but it's not one that most people can adjust without significant work.

Ask HN: How would you do first-party ads on your site?
I’m currently running RoutineHub which is getting around 5k unique visits and 17k total visits a day. I would love to earn money on these visits via advertising, but can’t bring myself to put a third-party ad network on my site. I’ve experimented with working with iOS developers to advertise their apps, but haven’t been able to keep them coming back. My average CTR is around 1.75%, so I feel like add value.

Are there specific communities where I can find advertisers? Are there more ethical ad networks that don’t scrape data from visitors to my site?

I researched that when my wife and I were about to get married.

I no longer have the link, but I found a study saying that birth defect rates were higher in mouse offspring from fathers that experienced the treatment than in ones whose fathers did not.

If you weren't wearing a seatbelt, then yeah, that's a fair characterization.
The software fix was the stopgap solution to a design side effect. The stopgap solution was also not that well designed, and ultimately confused the pilots, who were deliberately untrained in the changes.

Why deliberately untrained? Because the whole selling point of the design was that you wouldn't have to retrain your pilots because it would handle just like the old plane.
And yet many choose to abstain. The advertising is a problem and should be banned, but that's not reason to dehumanize consumers by denying their agency. People do have a choice and they should be reminded of that at every opportunity.
I think this is the part where i use "could". This is simply not possible today. Doctors dont really know or care how much "you" will be charged vs how much they get paid. If there was more transparency, you could imagine doctors and patients working their way out. People would see the inefficiency, and yake counter measures, both as care giver and care taker.

I have heard multiple stories now whete independent practices now just want cash, without insurance, payments for much cheaper, and they get paid more in the end.
I started having the exact same problem when I bought my latest Dell laptop. This was infuriating at first, but slowly I got better at avoiding the problem. (Still somewhat infuriating at times.) Periodically I'll disable the trackpad entirely via xinput if it screws up my typing too much.
> autonomous electric vehicles

Not to argue, but this doesn’t exist. Not really. Not on the market. Rail, however does exist. Further, what is the mileage equivalent of cars vs rail? I don’t know, but I think it would favor mass transit rail.

You also compared electric cars to taxi drivers - that’s odd.

> Rail systematizes discrimination

Can you expand further on this?
I have oozing derision for incompetence and stupidity. This dates to my childhood when I was always one of the smarty pants kids in school.

It was heavily fostered by my high school drop-out father who had enormous derision for "overeducated" but incompetent fools and he wore it very aggressively on his sleeve. As my post-secondary education crept towards six years of college, I've actively worked at toning down my contempt for the "overeducated" as it was gradually turning into hypocrisy. ;)

I'm critiquing a paper basically coming out of the White House that can't get a simple and obvious fact right that "climate" is not remotely the same thing as "daytime January temps."

It's clear in my mind that part of why the paper gets this important detail wrong is that a high percentage of people with white collar jobs have spent precious little time outside. They don't do much if any manual labor out of doors. They don't walk anywhere as a form of transportation. They don't go camping.

The well off in developed countries are increasingly out of touch with how weather actually works and how it impacts people who need to walk in it and what not.

I didn't want to spend a lot of time getting into the psychology of that, but I did want to in a nutshell capture the fact that people of privilege who spend the vast majority of their lives either in a building or traveling between buildings in a vehicle are failing to grasp something fundamental that would have been far more obvious to anyone a hundred years ago. This new norm of people spending so little time out of doors came into being within my lifetime.

When I was young, people walked places. Middle class and upper class college students took summer construction jobs. People routinely slept with the windows open.

Etc.

All of that has largely gone away in recent decades. We now have people in the US who only ever visit the outdoors during pleasant weather as a form of recreation who have little experience dealing with weather for purposes of getting anything practical done.

If you think "chronically housed" is some kind of insult, I'm open to suggestions for better ways to succinctly express all of the above. I'm a freelance writer by trade. It's absolutely not a best practice to have a multi paragraph derail at the start of an article to try to explain a concept of that sort.

But I think it is essential to paint a picture that "you folks writing policy papers -- who hardly ever go outside -- have a giant hole in your experiences that is a de facto barrier to understanding the problem space and here is the reality on the ground."
Yeh. Though I think it’s not explicit enough? A bit open to literal interpretation only.

I actually see it as “too little” new information that’s of utility to the general populace.

We spend then “too much” time focused on “too few ideas that matter”.

Like what celebs eat is discussed more than environment, and on and on. Too little new progress is made to satisfy these less discussed but ultimately far more important problems.

Thinking Keynes, our demand has been nudged to focus on consumerism, celebrity, gainz!. But we maybe need to balance that with the demands of the literal majority being shat on.

I’ve seen it discussed here too, that focusing on poverty via a statistic emotionally numbs analysis, ignoring that it’s still hundreds of thousands or whatever number it is, of real people barely scraping by.

We’re fetishizing opinions that we’re obliged to import as education from our parents and institutions, which is unavoidable. What is avoidable and manageable is the content of those opinions.

Free speech is generating whatever syntax you want. You’re not owed a society that kowtows to the embedded semantics.

I think the author is going out of his way to try and sound like a grizzled
veteran of career pragmatism, but I think he's just giving advice on how to
make your life harder. He's basically trying to find some idealised
description of "how things are" and adivising you that, well, that's how
things are and you should shut up and suck it up, or you'll never go anywhere
in your life.

Well, what kind of advice is that? You should just blindly follow what
everyone else does, regardless of whether you like it or not? That's just
self-limiting.

Burnout is a thing because people who want to do something radically different
convince themsleves that their only option is to work for a profit center, or
something equally soul-sucking and don't use their brains to find a worthy
alternative and make it work.

There is nothing to be gained by limiting yourself to what seems like "how
things are" and trying to do what it looks like everyone else is doing. That
way you can only hurt your prospects for personal development and progress.

Oh wait. Now _that_ is solid advice. That is 100% true.

> American highway system is arguably one of the best in the world

No, I'd say the German Autobahn system is the best in the world, followed by France (expensive) then UK, before USA.

USA is good because they tend to go to central cities, where European motorways deliver to a ring road. You can commute to work on a US motorway, but between cities they aren't special.
