Let’s think it out (as in: add your thoughts). If it’s for goods, you don’t need a human size pod. You can scale pods to a size that represents goods that make sense to transport quickly. Obviously you want benefits that come from standardisation, like containers give you.

Fully automated transport between all major cities for anything less than a metre diameter? I think that looks like the future. Mail, Amazon, fresh produce, run as a stream rather than in large batches, automatically routed, staying off highways. More efficient stock management that can react to surges in demand. Charge for it with spot pricing so high value items get priority.

Edit: produce sounds a bit silly but taken to extremes might be interesting. When you deliver a ton of lettuce, it’s sold as a stream. Someone gets the fresh stuff and someone gets the three-day old stuff. If you can reorder every 30m, everyone gets fresh. Smaller shelves and stores, maybe no store except online.

I agree that this statement could be true. But is it provable?
Then put a lock on the trash bin and give a key/access code to the recycler. Problem solved.

In my country we have poor people making a living on recyclables. They usually carry carboad by push carts. I would have a problem if these vulnerable people got prosecuted for cardboard "theft".
Journalling protects metadata writes (file names, dates, sizes, permissions, root block allocations) not file content writes, such that a FS can be brought up quickly after a crash. If you want transactional/atomic file ops, you need to implement it yourself on top of existing mechanisms, like transactional databases have been doing for ages.
Thank you so much for all your encouragement.

Wanting a few more details I googled that and found: https://lwn.net/Articles/559147/

Not sure I understand the importance of this...
I'm surprised that they didn't mention numba.jit, which solves the same basic problem as pypy (faster numpy calculations) but in a different way that is easier to mix with existing python frameworks.

For example, TensorFlow with numba preprocessing is easy, just install both packages and it'll work. TensorFlow with pypy requires a 5 hour compile and 40 GB of temporary storage. Plus some source code fiddling inside TF, if I remember correctly.

Even as an open source project, pypy should honestly consider who they're competing with for users and funding.
I don’t know where this “China did not change” narrative comes from. 40 years ago, Chinese people could not choose where to work, what to wear, where to live, what to study, where to travel. During the Cultural Revolution, neighbors could rat you out for “colluding with the enemy”, whatever that means. All of that has changed. Hundreds of millions of Chinese travel abroad every year, and nearly everybody returns willingly. What part of this great change looks like “China did not become more free”? It isn’t even some footnote fact, it’s a huge boulder staring in people’s face, and people can’t see it.
I wonder if a part of this mindset can be explained by the inability, i.e., lack of skills, to deal with confrontation. We all have to confront people and life circumstances at various points in our lives in order to grow, and if we don't have the skills to deal with them, fight or flight kicks in. The latter, overtime, result in a gradual buildup of low self-esteem, resentment, and anger.

Dealing with confrontations is a skill that can be learned, like most of the life skills out there.
It does change the meaning IMO. It means than 3% of the time you should be doing "premature" optimization.

The point of most people referring to this quote is never try to optimize anything as you write it. First build your system(?), then measure it, then optimize it. Knuth's point is that this attitude is ok most of the time, but sometimes it's not ok. Another way of putting this is that most of the code, for most applications, isn't performance critical. But some code is.

Sure, you can't always tell in advance, but sometimes you can. This is sort of the difference between terrible software that will always suck and well crafted software, no amount of measurement or after-the-fact optimization will turn that terrible software into well crafted software.

The other aspect that I think is often missed is that these observations are often made at different scales. You can look at relatively short algorithm (let's say merge sort) and it may not be obvious which instructions are the ones that need to be optimized and what the bottlenecks will be, execution units, data access e.g. So you start with a reasonable but maybe naive implementation and then you optimize from there. That's a pretty solid idea. But taking that idea to a higher scale level, e.g. saying we're going to build this huge system with a billion lines of code and so we'll just throw something together and measure it isn't exactly the same thing, that's a pretty problematic idea. You need to be able to anticipate what the bottlenecks in your billion line system are going to be because finding that out after you've written a billion lines could be a big deal.

[EDIT: and really this whole long story is why these sort of rules don't work. Because the people who know (have the experience/craftsmanship) don't need the rule and the people who don't know won't understand it. It's like reading a book about sword fighting and then trying to go into a sword fight... The reading can complement your training but can't be substitute...]
> It seems you are arguing something different,

I'm making an argument that the stark reality of what's hard in software development is not the simplistic "Rules of programming", which have limited utility.

The reason the "rules" aren't self evident (or followed), is because we live in the reality of disparate functionality paired with an ever-changing technical landscape. You can't just make a DB KISS abstraction and expect it to hold with all the different repository types like (rolls dice) Athena after using (rolls dice) CockroachDB. There are concerns that are not purely algorithmic vs data structure that are far more influential and important to understand. Even knowing these details and cases, becomes less useful as time goes on and new technologies emerge.

> I am having a hard time understanding what you have written

If you're not interacting with new environments, tooling, and problems, regularly (every year or 2) you don't encounter the real pain which is far more important to your career and your ability to produce functional software. Reading almost every postmortem, the number of lines attributed to "we changed the data structure to O" is dwarfed by "we learned that technology X does Y, so we had to do Z".

This is only incidentally related to distributed systems, which is indicative of a disconnect with the problem described. Of course when you sit around in the same environment for a long time, you can observe and optimize on structure and algorithm, but that's not getting you to market (you're already there) and that's the nature of maintenance...not just being a fire extinguisher who is on call.
Maybe some of it is theft, but some of it is clearly not. From the article:

> If magic pixies have nicked their waste cardboard then it means they don't have to pay a firm like mine to come and pick it up.

That's not theft in any moral sense, though I can't speak to British law. The owner wanted it gone. It wasn't owed to anyone else (or they wouldn't have to pay someone to take it away). A firm is upset they didn't get a contract, that's all.
We don't "know" this. We know they renewed the $400m US contract with Google. and we know they laid of 250 people but the two do not become "join the dots" to a risk issue for firefox.

We're told there is a pivot. We have not been told FF is being thrown under a bus.
Back in the late 90s, a mechanical engineer on the MIT solar car team was explaining the latest high-efficiency motor controllers for brushless DC motors, and my degree is also in Mechanical Engineering, so this could be way off. However, as explained to me, the highest efficiency brushless DC motor controllers in the late 1990s used a phase-locked loop to get some of the off periods in the square wave in the power conversion stage to be in sync with the switches between coils in the motor. Transistors don't switch instantly, and a good deal of your power loss is during the transition between fully off and fully on. By synchronizing the two parts of the motor controller, you get the coil changes to happen when that part of the controller is seeing dips in its power input, so you get less loss.
Me personally donating isn't going to make any difference, but put a "subscribe" UI as part of the regular interface so a big group of people pay each month, then I'm happy for them to take my money.

It's not moral grandstanding. I don't think the exec team earns their keep. It would be one thing if they were leading a growing non profit (that owns a for profit), but rather they're leading a quickly declining ship, all while their own salaries increase over time while they do a shitty job.

The ceo of MSF, who imo does a great job, is paid 120k a year.

Aside from the brand name of Coinbase, this seems worse than similar offering from Nexo (nexo.io):

- Coinbase APR is 8%, Nexo is 5.9%

- Coinbase max loan is $20k, Nexo is $2 million

I can see the appeal of borrowing against your bitcoin or other cryptocurrency, but I'm not sure if there's much value in borrowing $20k. If you're in a position to hold $60k bitcoin on Coinbase, do you really have a need for a 1 year bridge loan of $20k? At a rate only slightly better than a credit card?

One of the giveaways of totalitarian logic is that their enemies are simultaneously both inferior and an existential threat to their superiors. (Agreed, the small-c communist threat would not have required Nazi policies. The large-C Communist threat was something I think Goebbels might have claimed existed so long as a single spark of Communism existed to re-ignite that totalitarian untermensch-driven "revolution.")

(Another giveaway is lack of humour: I don't know of any famous totalitarian comedy, especially any that have used self-deprecating humour, but I'd love to be proven wrong on this point. Some regimes even banned humour:

Two judges meet on the way to their chambers. One is chuckling and wiping tears from his eyes. The other asks, "what just happened?"

"Oy, I just heard the most hilarious Stalin joke ever. But I'm afraid I simply can't tell it to you: I just sent the last person who repeated it to Magadan.")
2200 sq ft duplex is a farcry from an 8 story building in nyc. if anything, apartments will get taller and taller, and up in the clouds at the pinnacle will reside a single family home with a manicured lawn. a suburb in the stratosphere. the jetsons may not be too far off.
But it's great! They learn to pick-up when they're 'tricked' and they learn to chose.

Man, I remember when I started deciding things for myself... at 16-17! 'so you want to go to prep school, university, or eng. school?' WTF I don't even know what I want for dinner... I feel this is something that needs to be trained the soonest possible. See what you feel when asked to chose. Decide something. See how you feel when you've taken option A or B (or feel when you don't like any of the available options! And learn to think outside the box!). See what happens when you change your mind before you started A. Or after you've started B and think 'I should have done A'. With your parents, friends, teachers. It's amazing how teaching this to my little kids with a positive and caring attitude has shown me how hard and important it all is! And it's even harder for collective decisions!

Something amazing for twin children: they also have the opportunity (or the burden sometimes) to see how their choices affect others and how important negociating, defending, compromising is.

Those books that GP cited are gold. The whole Positive Education movement is, I think, a way to a better future, with balanced and reasonable members of the citizenry. And I ache for all the children with have parents that don't even have the tiniest bit of empathy and interest for their children.
I was trying to convince my boss to let me break off a piece of my Node.js program and rewrite it as a separate Ocaml process. Which he thought would take too long.

But then I remembered Reason exists and there is no argument about taking too long anymore because I can incrementally convert one function at a time if I need to.

I hope someone convinces the guy who shows up on Google under Rescript to use another name or something.

Why don't you ask Brendan Eich how much he was willing to be paid to be CEO?

This is all fine and good but it misses some much more fundamental drivers, not those that are narrowly instinctive.

If you want to play the violin beautifully, you have to practice for 10 years, there's no way around it.

One of the things that differentiates humans from beasts is that we have at least some sense of higher purpose and many of us derive considerable fulfilment from that.

For the most part, most of our education is necessary - and the ability to focus, to plan, to think beyond just a few steps, to control one's desires and emotions, to concentrate and balance one's life energies - this requires education and maturity.

Yes, it can be stifling in some ways, that's ok, we want our doctors and accountants (mostly) to be small-c conservatives. Others can write Operas.

But none of it comes without a formal journey at least in some capacity.

It's a neat experiment but I think it's hard to determine the results. The novelty of exploration in that context just might not be 'novelty' from the adults perspective. Try trading rewards for truly novel things, like, jumping out of planes, I wonder what the result would be.

thats really due to an oversupply in that particular suburb that you cite. In shaker heights, Ohio, you can get an 8 bedroom mansion for like 700k, or 2 bedrooms in LA in a single family home neighborhood.
As someone who in his (mandatory in my country) social year worked with "difficult" kids: for nearly every kid there is intrinsic motivations you can find. Of course that isn't easy and requires much more teachers and a bit more flexibility when it comes to which topics to learn, but good education is making every bodies life better and should be IMO much higher valued both in societal and monetary terms.
There are a large fraction of Americans who don’t have that leisure though. They’re forced to work long and arduous hours at meaningless jobs for low wages, because they can’t survive otherwise. Hard to see yourself as someone who is valued beyond their economic output in those cases.

Decent high school grades are not that hard to get. It's not 'strangulation' to have to take 'English, Geography, History and Math'. I wish I had paid more attention in English class, I did not respect how important it was going to be until later in life, for example.

Qlik and Fortune Magazine Collaborate to Start a Data Analytics Site
I remember thinking that the "web platform" thing seemed like a good idea, and I knew it kind of petered out, but I go back there now and it says it was around for 3 years and just Pointer Events was "Done," and you go look at the "Not Ready" HTML section and it's kind of a mess and there's double copies of all the elements, one in Japanese... I'm sure there's actually been some rot there so it's probably actually worse than it once was, but still.

What they don't seem to have done is what I sort of assumed was going to happen: taken MDN, stripped the XUL stuff out of it and just airlifted it over, then make the now-duplicated MDN stuff just redirect to this new space and shifted their efforts there. I suppose the issue is getting consensus on doing that, a big move, from the MDN side but as Mozilla (at that time) was committing support to the new endeavor, I dunno, it just seems like the thing to do.

Instead they kind of had a weak period of double effort and nobody shifted over, and this just died.
