I think the rationale goes something like this: how do you create a fixed size array? Of structs? Where one field is another fixed size array of timestamps? And on the stack?

Without some kind of default value, you end up with a lot of nested constructors and loops initializing array elements and fields, versus just zeroed out memory.

C++ does the constructor thing but it seems complicated and finicky when you don't have a zero-arg constructor. When I looked at Rust array initialization it looked somewhat limited, but maybe I missed something.

I'm not sure if every type really needs a zero value like in Go, but it seems like standard types like timestamps should, so you can use them this way?
I didn't state that no one builds anything in Rust so I have no need to square it.
Electric cars help. CO₂ sequestration helps. Reducing consumption helps.

Well it can matter if it turns out the issue wasn’t engineering so much as clearly communicating that it’s a different aircraft so the pilots can be trained correctly.

I totally agree about the importance of being strong. But I don't think that dead lifts are the only way to get strong enough.

You need the upper body strength to avoid supporting yourself on your wrists. They should just "float". Having good forearm support helps, but it's not enough if you're weak.

And core strength helps prevent back pain. Along with a chair that helps you sit up straight, and provides lumbar support.

Wrist curls and reverse wrist curls have also helped me a lot, for both wrists and elbows. I also use self-practice wrist locks for strengthening and stretching. Or with a rubber torsion rod.

What do you think is a better way to fund a manned mission to Mars? It's hard to argue with the progress that SpaceX has made - and that wouldn't exist without VC funding. Meanwhile NASA continues to operate at the whims of Congress. It's doing fine, but it's not looking for any moonshots like it was 50 years ago.

My own brother was exactly that way (good enough to be one of the best in school and hold his own at an elite university, but not close to good enough for any kind of actual competition) but my understanding is that he was only ever trying, never doing.

There's a huge difference between learning something because some external pressure dictates that you learn it and truly immersing yourself in something and just letting go. Math isn't that exciting for most people, so the vast majority of people never cross over to the latter. So the extremely small percentage of people that are able to cross the chasm and deal with math natively can stand out.

I don't agree that connectivity and applied science are two separate things. We don't get to netflix without applied sciences: encryption, compression, networking, neural networks. I don't know why the author said that. He has a degree in computer science
Thanks for sharing. It's certainly food for thought. I was trying to picture this sort of leadership by consensus applied in different parts of the world where I've lived. Although it might work with some success in a few places, in most I could only foresee catastrophe. Then I was reminded that Sweden has a really good education system. Maybe there's another lesson to draw here, that in order for consensus (democracy?) to work, it's worth ensuring that the minds that will voice their perspective actually have the ability to work out the issues.
My career has progressed over the years as I learned about opportunities in the tech world.

I first started out in HTML web and email design, but I found it to be too difficult to make it into anything more than beer money.

After talking to other people in the industry, I started making websites in simple PHP. Eventually I migrated to WordPress and spent a few years building my LAMP stack skills. WP and PHP becomes a nightmare for any large project, and I found myself getting burned and burnt out by clients and PHP issues.

Along the way, I picked up JS and got good enough to pass interviews. This led to a one year gig as part of a marketing team, cranking out code and dealing with non-technicals ruining projects.

The JS frameworks started exploding, and I found work as an AngularJS (1.x) dev. This got me into corporate work. I got exposed to more tech and my resume blew up.

Nowadays, I work in React and NodeJS but my experience gets me jobs across all of the stacks I dabbled in.

My recommendation is to get a job, learn all you can, coast. Then use some of your free time to educate yourself for your next job. Get more skills, rinse, repeat.
True, maybe we should have clarified that in our article.

The point we were trying to make is different however. That point is this: in reality most legal data, in its final authoritative form, at least re contracts, is stored in a scanned pdf of the signed agreement, ie an image not the original Word doc containing semi structured data.

Granted, if lawyers didn't scan docs as images and hold only those scanned images to be the authoritative data on a particular matter things might be different.

Lots of projects in the works at law firms and in house legal teams to try and maintain contracts as structured, or at least semi structured, data from cradle to grave but still old habits of scanning contracts persists.

Not sure if that adds clarity. Be good to know. If it does (or if it doesn't) be good to understand so we can improve our content :)

> “Why We Can’t Solve Big Problems”

I think it may partly be because most of human civilization is still basically slave labor.

You indenture some people and you tell them what to build.

People don't care about problems they're not supposed to take care of. It's a detriment to them if they do.

This kind of makes it tricky to take on tasks like say, space elevators or arcologies or extraterrestrial colonies. You need expertise and constant collaboration from so many different domains it's hard for a single organization to have enough musclepower and brainpower for, even with contractors.

Then there's the tribalism. Governments may have the resources to take on global/space-scale projects but they generally try to hinder other governments, even within the same nation.
Why is it always space?

Good question. The best off-earth real estate in this solar system is worse than the worst on-earth real estate. It's easier to build colonies in Antarctica or underwater on the continental shelf than on Mars. Mars is small, cold, and nearly airless.

We're not short of low-value real estate, after all.
I truly enjoyed reading Saifedean Ammous ‘Bitcoin Standard’. Among other things he explores the relationship between the soundness of a monetary system, the establishment of the gold standard and industrial revolution and technological progress and what he calls ‘zombie industries’ kept artificially alive by loose money policies. Highly recommended.

It is in so far as the 737 MAX had an inherent stability issue due to the mounting position of the larger engines. And every system that can directly affect the control of the aircraft is by definition safety critical. Otherwise the majority of aircraft systems wouldn't be as all modern passenger aircraft can glide without engines pretty well. Following your logic engines wouldn't be safety critical neither.
ISCHEMIA: Invasive Strategy No Better Than Meds for CV Events

https://www.tctmd.com/news/ischemia-invasive-strategy-no-bet...

I haven't been able to find out what the medical alternative treatment consists of other than changing diet, losing weight, stop smoking, stop drinking, start exercising, taking statins, etc. These are, of course, all good and useful things, but I knew a man who had a quadruple bypass and refused to make any lifestyle changes. Maybe not having a bypass would have focused him on making those changes.
That's the designers fault then. Most alignment issues are caused by fonts and their bounding boxes that are based on line height (fonts have a default line height they ship with). One of the errors I often see is that designers define font sizes based on the letter sizes, not based on their bounding boxes or how well they fit into the bounding boxes that should match the defined component sizes within their design system. Design systems have spacing scales, and fonts (and their bounding boxes) should be part of it.
Nope, you are just echoing the basic understanding of the tech that is on every bitcoin propaganda outlet.

Each node can still steal money from the node next to them by turning hostile such as not passing the secret and closing out their channel and getting time locks to expire, which is many magnitudes easier than cracking encryption or stealing a private key. The network has already been DDoSed. Now imagine the incentive to do it when it handles millions of dollars.
This is a really good idea. My take on this was to use Prolog but it turned out people did not like Prolog: https://github.com/davidk01/cwacop. The project is dead at the moment but being able to work with infrastructure using a hybrid model of logic + imperative drivers I think is fundamentally a good idea.
“Does it spark joy” is very useful heuristic. But what about things that have an emotional attachment? Or were really expensive?

I’m working my way through “it’s all too much” (
https://www.amazon.com/Its-All-Too-Much-Living/dp/0743292650) and it has some great tips. If something is emotionally valuable you better be displaying it or treating it like it’s valuable. If you’re not it’s probably dead weight. If something was costly but you’re not using it, you’re paying MORE for it by storing it indefinitely. And so on. Tips on how to talk about clutter with the family etc. Very useful book.

That was the same Google.org that had weird problems with its leader interfering in middle eastern politics, to the extent it became practically an extension of the White House?

I remember google.org - seen from the perspective of an engineer in a far away land it was frankly just kind of weird/creepy/slightly sinister. Yeah the flu epidemic predictor thing was kinda cool, except I never heard anything about it since and I'm not sure it's ever actually been useful for much.
What we need is progressively stricter tariffs paired with looser immigration laws. We need to force companies that want to efficiently compete for our consumer demand to in-source process knowledge and manufacturing.

It's easy to say you don't need to be a genius to be a mathematician when you're a genius celebrity mathematician.

Personally I gave up on math as a career once I realized all the people who got into top grad schools for math were like international IMO participants, USAMO or equivalent at least, started taking classes beyond calculus in 10th grade, etc. Even though I love it and even have an undergrad degree in it, and maybe could have performed that well if adults in my life nudged me in that direction, the fact that there were so many people who would always have massive advantages turned me off from it.
I'm disappointed Stigler's law was actually coined by Stigler.
Switching to a Kinesis keyboard has helped my hand/wrist pain quite a bit. It seemed to be steadily getting worse, and disappeared after using the keyboard for a couple weeks.

Another thing that helped is the book Conquering Carpal Tunnel Syndrome[0]. It has a good set of stretches to do categorized by what's bothering you.

Even more impactful IMO, it teaches a technique they call the "stretch point": very gently & slowly stretching until you feel the first hint of a stretch, then pausing and waiting for the feeling to release, over and over. Versus what I was naturally doing before, which was to stretch until I really felt it, and hold for a while. The theory is that the slow/gentle stretch+release pattern is more effective for the smaller muscles and less likely to damage them.

Ten Ways to Use CO2

If you're into prevention, get an ergo-aware keyboard and mouse if you feel any discomfort at all.

The starting points - and for many people, perfection - are a split keyboard (like https://kinesis-ergo.com/shop/freestyle2-for-pc-us/), ideally with the center elevated ("tented"), and a vertical mouse (like https://evoluent.com/products/vm4r/). They have almost no learning curve. Kinesis has a 60-day money-back guarantee.

These products should leave your wrists and hands at the same angles as when they hang at your side. Let your arms dangle freely, bend your elbows, and type/mouse.
Maybe that’s not true, in the long term? But certainly easier and more profitable in the short.
> Most of it is wasted intellectual effort.

It is highly stimulating intellectual effort though. Sometimes I sit down and spend hours just thinking about the best way to do something. It's some kind of philosophy: the abstractions we create reflect the way we understand things. To write good code, we must study the computer science and the problem domain itself.

Without this, it's just boring mechanical work. Once the project has been figured out it ceases to be interesting. Some of my projects are unfinished because I can't justify spending more time on them even though I know exactly what must be done.
The problem is Intellectual Monopoly laws.

Imagine you have 8 billion processors but you only provide 8 million of them with disk access.

Very few people have access to the information necessary to build innovative products. Instead of waiting for BillG to solve the energy crisis and healthcare delivery and new kinds of toilets for everybody, let's abolish Intellectual Monopoly laws and unleash the power of all 8 billion processors on solving these hard problems.

I would love to say "No! This is not the case at all! One can act in either mode just fine. We're not prisoners of our tendencies!"

But from my experience with myself and friends, I think, sadly, this is typically not the case. People can act in either mode, but tend to have a proclivity, whether born or cultivated, for one over the other. You can do the other, but it will require extra effort for lesser results.

There are unicorns that can do both brilliantly. But much fewer and farther between than those who claim they can do both.

I've always been strongly on the engineery side myself, but have tended to fall in with artistic types socially. In my experience, artsies often fall short of being able to articulate ideas concretely, and thus can't easily interface with people that need a delineated plan. Which makes us engineeries tend to think they're soft brained. But in fact, they can often execute even highly complex systematic projects well. They just can't tell you how they did it.
Peer Review: New initiatives to enhance the value of eLife’s process
Seems like a rash generalization instead of taking responsibility and confronting the problem yourself.

Ergonomics is something that seems like a mystery to almost everyone. People might pretend they have it figured because testing claims is so difficult. I have been at companies that cared about ergonomics and would buy split keyboards, standing desks and more if people requested them.

When you use X and then a substitute Y arrives that is 10x cheaper and more convenient, you'll switch to it.

Using robotaxi network will be much cheaper than total cost of owning a car, mostly because cars are dramatically underutilized.

On average a car is used 1-2 hrs a day out of 12-16 hrs it could be used as a robotaxi. To start off we have 5-7x price difference.

Then most use is not shared. Assuming robotaxis will be used by 2 people on average, it's another 2x cost difference, 10-14x combined.

The cars will be much cheaper. Think $25k Toyota corolla, not $45k SUV or pick up truck. Fleet operators will ask for cars that are cheap and reliable, not for luxurious interior.

The cars will last much longer. 500k miles vs. 100k miles of a typical car for personal use. 500k is already a reality with Teslas (https://qz.com/1737145/the-economics-of-driving-seven-teslas...) and Tesla is working to make 1 million miles cars.

Not to mention that GM spends 3 billion dollars on advertising each year, which goes to increase the cost of your car.

It'll be a no-brainer to pay $200-$300 per month for (effectively) unlimited robotaxi service than $400 per month for a lease + $100 month for insurance + fuel + cost and inconvenience of refueling.

Furthermore, you won't be able to buy those cars.

Consider the following scenario to its logical conclusion:

Tesla (or whoever) introduces a robotaxi service.

A car that costs $30k to make can be sold for $40 k to you or put to use as a robotaxi and make $100k - $300k over its lifetime (big spread because it's hard to predict how the pricing will pan out).

Why would Tesla sell a car to you for $10k profit if they can make $70k profit?

For the first 10 years they'll be busy making cars exclusively for robotaxis and they'll prioritize grabbing market share. There will be no $40k self-driving Teslas to buy.

But won't GM or Ford or Toyota sell me that car?

In 2008 car companies went bankrupt because of 20% drop in car sales.

If robotaxis take off, they'll shrink car market by way more than 20%, permanently.

I can't see how this won't end up in bankrupting pretty much every car maker as we know them.

Those that will have self-driving technology will also switch to making robotaxis exclusively.

Those that don't will either become OEMs to the kinds of Waymo (and eventually be bought by them when they vertically integrate) or go bankrupt.

Privately owned cars might become like yachts: sold in very low numbers to multi-millioners.

Larger particles (50-100nm) are typically soot.

> We've moved our entire web presence to GitHub to become even more transparent. Here, you can see how things have changed over time, propose improvements, or even take our ideas and make them your own..

Sorry but to me this is screwy. Why do I have to spend time navigating github to find basic info about the firm if I am just curious? Why is it beneficial or implied that anyone who is anyone knows the secret handshake of finding what they need by finding it in this manner? Why is it not possible to have transparency with a 'normal' website and then if there is a reason point people to github?

From wikipedia:

"Bloomberg Beta consists of six full-time employees: Roy Bahat, Karin Klein, James Cham, Shivon Zillis, Morgan Polotan and Shaina Conners. Bahat was previously the President of IGN Entertainment and was the chairman of Ouya Inc. until June 2015."

The github site says nothing about who these people are either. Sorry they are not 'well known enough' to present this way. This is not 'everyone knows who Bill Gates is'.

Example: https://github.com/KarinK

This is not transparency it is the opposite.
I'm of the same view. Why do you suppose DSLs proliferate when people could just as easily use Python or Ruby as their configuration language?
