Also, you report from MIT is 10 years old. The past decade has shown the most transformative decade of grid-related technology development in the past century, and the MIT report from 10 years ago didn't anticipate any of it. I don't blame them, most people were caught way off guard. But there's no reason to read it today except to study the history of what people were thinking back then. We are in an entirely different age.

"Shopify is a really smart company. It wouldn’t tie its own hands for no good reason."

Don't underestimate companies ability to do 'only one thing' and 'screw everything else up'.

Shopify has evolved on top of 'a neat thing done well early on' and everything is about scaling that.

I've worked at very successful large tech companies who were actually terrible at doing any other tech than the product they sold.

Why isn't Google doing a Stripe API? Why isn't MS? Why isn't Apple? Why isn't Volkswagen?

> A species that colonizes will fill the galaxy in a few million years unless it just decides to stop.

I think this may be making some weird assumptions about motivation. Let’s say, for the sake of argument, that travel at 5% of the speed of light is practical. Would you be signing up to go colonise a planet around Alpha Centauri? What would be the motivation opportunity such colonisation? Who would pay for it?

If interstellar travel turns out to be permanently slow, difficult, and expensive, then that may cast doubt on the idea that anyone who theoretically can spread out all over the place given a hundred million years actually will.
Easily. It's about reducing the barrier to entry when someone wants to look at your demo. Every extra scheduling email you send is a chance to lose someone in the funnel. $6 extra a month? Irrelevant. Product probably underpriced because the guy can't demonstrate how many calls he's saving them.
2009 rectangles were pretty cool. They had scroll bars that were visible at all times, minimal whitespace and generally better usability and functionality. No purple gradients and huge buttons, responsive mess that serve what I consider mobile-first-desktop-last rectangles. It's becoming harder to find pure rectangles even, they've become soft baby-like with rounded corners to sooth our senses!

The article fails to realize the future of energy in Texas is wind power hundreds of miles away from people. This is the largest concentration of wind power in the US and is still growing.
Author and professor Timothy Ferris explained this well in the PBS documentary Life Beyond Earth with a Christmas tree light analogy. Ultimately it comes down to how long other civilizations last for and are willing to communicate. If a civilization either kills itself off or turns inward (cyberspace life, no radio outward communication) then the chances of concurrence decrease significantly.

Just curious, as a native Italian speaker, how hard did you find learning Latin and what was the hardest part for you?

My native language isn't a Romance language, but I have also spent five years learning Latin in grammar school and for me, learning both the vocabulary and the grammar was hard, hard work. I always assumed that for a native Italian speaking person it would be probably a lot easier.

Art Of Manliness Podcast #619: What Driving Tells Us About Agency, Skill, and Freedom

Self-driving cars are the future of transportation, right? No more car maintenance, no more traffic, no more accidents. It may sound great on the face of it, but in this thought-provoking conversation, Matthew Crawford argues that shifting from being a driver to being a mere passenger represents a kind of existential risk.

Strange, the article doesn't really show a lot of concrete evidence contradicting the basic underlying contention/assumption of the "dark ages": that civilization went backwards in terms of governance, institutions, infrastructure, architecture, arts, engineering, and science.

It states that cities shrank. It states that secular schools closed and the church "filled the void". It states that infrastructure crumbled and wasn't replaced like aqueducts. It states that documentation and writing decreased to the point that scholars can't get a good view of what was happening.

“The idea that’s completely out of fashion these days is that it was dark because it was morally worse,” Ward-Perkins says. But these days, he notes with a touch of dark humor, “everybody pretty much accepts that humans are pretty horrid all the time.”
In my experience business titles don't mean much. They don't actually indicate seniority, managerial/leadership ability, expertise, knowledge, understanding, and a multitude of other valuable and praiseworthy attributes.

Ever speak with someone with a <blink>Fancy Ass Title</blink> only to discover the person severely lacks the experience and thoughtfulness you'd expect from the title? Depends on the company, of course, but it happens at startups and corporations alike.

However, there is some utility in recognizing when someone flaunts a lofty title aggressively, they are most certainly not the person you should be dealing with to get something done properly.

It seems that every new [especially Saas] startup has a very similar "feeling" website. In terms of what to expect, fonts and colors used, even the feel of scrolling. Reminds me of Apple product pages from a few years ago. Are they using a common template or something?

Metal hydrides have been proposed as a possible solution. We talked to a small R&D firm years ago that had proposed putting power stations in remote areas where energy is immediately converted into a metal hydride; in their case, magnesium hydride. I remember the process of reforming magnesium hydroxide back was fairly energy intensive, perhaps too much to be considered efficient.

The benefit of storing magnesium hydride is it's much easier to store safely in large volumes than hydrogen gas. Hydrogen gas leaks through everything, it's just so small. On the other hand, you have to collect spent material (presumably at "gas stations") and return it to the energy farm, which is more complex than the one-way delivery system you'd have with hydrogen. Still seemed like an interesting idea.
Another Onion gem from 2000: “Area Man Consults Internet Whenever Possible” [1]

> "I was on the phone getting directions to a restaurant we were going out to," Pamela said, "when Larry started yelling, 'No, no, don't ask! I'll find it!' So he opens up mapquest.com, enters our address and the restaurant's, and within 10 minutes, he had complete door-to-door directions printed out."

> "That's right," Larry said. "And she wanted to get a pen and write down the directions by hand."

Some people, I’d venture a guess at 1/100 people, can and do use printed text compulsively. Other people, I’d venture a guess at closer to at least 9/10 people, can and do use screens compulsively.

This topic comes up a lot and I am always astounded at how people so candidly compare screens to books. Many people I meet in my day to day life do not have the concentration required to read a novel. Maybe its time to put my glowing rectangle down.
Quantum computer makers like their odds for big progress
Well one point is that information exchanged through a screen is always mediated (in contrast to the physical world). Screens have a form factor, screens usually have a third party organising the content that is being exchanged. Screens are flat surfaces. You operate through screens in a sort of purely functional input-output rather than spontaneous way.

So the screen being a technological and commercial artifact, imposes a lot of rules on how we interact through it, sort of like an API. And that's noteworthy compared to the time before we were interacting through screens.
> Root cause analysis is harmful because it artificially limits your investigation to a predetermined "single" error or fault.

The Five Whys specifically does not stop at a single root cause or fault, that's why it's the five why's and not the one.

Moreover, robustness cannot emerge from a single event no matter how much you analyze it. It comes from continuous improvement processes, quality assurance, war games, service level analysis, etc. It's a multi-headed hydra of efforts to improve a system. One of those things is RCA of service-impacting events, or manufacturing defects, or customer complaints.

This is like those "considered harmful" blog posts so fashionable a few years ago. So it turns out that if you blindly and inaccurately follow a generic process, it might not work out great. Who knew? It's almost like there might be subtlety involved.
We've got a `gratitude` channel in Slack for this exact thing! Its only purpose is to call out great work and nice gestures coworkers have done. Provides a nice little pick-me-up throughout the week.
This is far more complicated than using the electricity directly, at time of generations, when possible. The most clear headed, short form, explanation of hydrogen's potential I've seen is here:

https://about.bnef.com/blog/liebreich-separating-hype-from-h...

We will likely end up using hydrogen in three situations: chemical feedstocks, some industrial heat processes that may want some reduction too, and backup grid generation. Switching pipelines to hydrogen has huge, unsolved problems. The energy density is far lower, meaning that even with current demand, natural gas pipelines repurposed to hydrogen would be inadequate. Already, building new pipelines for NG is so difficult that LNG storage is deployed to relieve congestion. Hydrogen would make that far worse. And there are many small things, like making the pipelines robust to the damaging effects of hydrogen, and even coming up with some sort of odorant like the mercapten in natural gas; we don't have any chemicals that can work at the moment.

There is a lot of appeal to hydrogen, and with a decade of intense industrial development we may be able to make carbon-free electrolysis derived hydrogen economical for many use cases. But it won't be many, IMHO.

Ideally a destructive command shouldn't be accidently triggerable. At the very least it should require some positive confirmation. Alternatively, a series of actions could be required, such as changing the capacity (which should be the comqmnd where the double checks and positive confirmations happen in my opinion) followed by changing the services usage.
We have an amazingly beautiful world, from lush forests to deep blue oceans, with billions of wonderful humans, yet we choose to spend the vast majority of time on a virtual world we’ve created.
I think the point is that yes, this technology as it exists today is only commercially viable for some products which are only appetizing to a wealthy elite market. But that's an advantage, it provides a stepping stone. The profits from that can be pumped into R&D to further commercialize the technology, and build a commercial ecosystem. Perhaps at some point in the future the technology will be applicable beyond the simple crops planted today.

In Tesla, the roadster not only proved that electric cars can be good, but that they can be better. Though not everyone can afford a roadster, enough people could and that car was a launch pad for R&D of electric car technology, manufacturing (which it turns out is truely the hard problem in building a car company) and consumer desire.

> Wouldn't your thesis predict more political problems in areas of greatest diversity

No, it would predict political division along racial lines, which is precisely what happens.

This is a weaker predictor than the racial demographics of the voters.

Are you using "diversity" as a synonym for "nonwhiteness"? Because if so, you're correct, but you could probably phrase this more explicitly.

I think you have misunderstood the parent comment. The suggestion isn’t to create configurable anc headphones but instead to create a device that is able to cancel out the sound of your voice from the ears of other people around you so you can speak in public privately.

The problem is you can’t possibly work out exactly how and when the sound will hit each set of ears around you to be able to direct a beam of sound to their ears (assuming it’s even possible to have such directional sound)

The problem is significantly easier with headphones. You have a headphone and speaker in between your ears and the sound. The distance between the microphone and your ears is constant so you can perfectly time the negative sounds.

> It bothers me that instead of adapting the tool to us we have adapted ourselves to the tool.

Isn't that always the way it is? Society made obvious shifts with the invention of the car. With the invention of the printing press, we adapted by teaching people to read the things it produced.

Adapting to our tools seems like the reason we live anything like we currently do. Otherwise we'd still live in communities in the woods, with technology that has adapted to us (which is an interesting thing to think about).
I keep wanting to try that! Sharding the index would be really cool, and would definitely allow for a seemingly infinite index size. The barrier, as you were getting to, would be making sure index shard downloads could keep up with typing speed.

Definitely something I'll try experimenting with in the future, so... watch this space, perhaps?

No, it's cheaper even with battery backup:

https://www.lazard.com/perspective/lcoe2020

Stored solar, no subsidies: $81-$140/MWh

Coal: $65-$159/MWh

And then with solar, 40%-70% of consumption will be direct without storage, at $29-$42/MWh, which pulls the all-in cost of solar way below coal.

And that's for projects deployed in 2020. Wait 5 years, the typical timeline for bidding and installation for utilities, and any utility that isnt planning for massive renewables and storage is simply bilking their customers.

I think you may be mis-representing what I am saying. You can generally sense if someone could be a possibly good fit in 20 minutes of conversation. The ROI of an additional 500 minutes of conversation doesn't change the error bars. They could be great leetcoders, but not a good colleague. Hopefully the first 20 minutes gave you a sense of their soft skills, but even those can be mis-represented in small bursts that are un-representative of how the individual typically communicates on the job.

You're saying I am saying we should randomly give jobs. I am not. I am saying it should be, at max, a 1 hour phone call. Background checks can verify past employment and job titles.

Self-hosted Stork is definitely possible, and definitely something I want to build! I've been focusing on a different type of user for the 1.0.0 (the user who wants to paste in a single script tag), and there are still some last experience improvements I want to make for those folks, but I completely recognize the value of self-hosting code like this and want to build something into Stork that will fill that niche, as well.

For now (and I haven't tried this for self-hosting, so use at your own risk) -- the whole project (incl. the final JS file and the WASM blob) can be built from source. Tweaking the build a little bit would probably get you most of the way there.
