D3.js is, to me, one of those tools that makes things possible rather than making things easy (although I only use javascript once every year or two so it's always a slog). This is big: it's like a zero-to-one step, rather than incremental progress.

This fall I made an interactive visualization of the fine-grained plate tectonic model I have built for the Himalaya and Tibet for a research project[0]. The model building process (i.e., finding the relative motions of the plates) is largely solving a system of linear equations, so it's not immediately apparent what the results really mean and whether they are acceptably realistic.

D3.js allows me to explore and understand my own scientific results so much more thoroughly than the static quiver plots that I was making in Matplotlib--being able to pan and zoom a globe (not just a projected map!) and see the tectonic plates move through time is phenomenal. Being able to share the results so trivially as a web page is a huge force multiplier as well.

Thanks so much, Mike!

It has been fun trying to build a brand around the word grease. We came up with GreaseBoss for hardware product and GreaseCloud for the software platform
I agree. But your suggested acronym to fix it is a bit over the top. Perhaps: Uninteresting Friendly Object.
You think the range officer just let this one get away? They shut down highways during testing, let alone airspace.
Most hardware engineering is done ahead of time without a full production style environment. This is because the cost of iterating is much too high. You can't build a bridge every time you want to try a new cable or bolt. It forces designers to make models and assumptions about their systems and, inherently, puts downward pressure on complexity. It also forces them to truly understand the principles behind what they are building.

The fact that Perseverance and other Mars rovers have been successful is amazing and took an incredible amount of work to accomplish. These are complicated systems that were vetted using models and simulations without ever having been run "in production". This comes at a high cost.

Critical software is never tested in production or run "in system" before it is deployed. Airplanes, banks, medical systems all require extensive validation through testing on models and simulations. You can't test your changes for the first time on a live aircraft or living tissue. Costs reflect that.

The truth is, a lot of software is not critical. You can get away with hacking / trial and error type development and never fully understand the system you are helping build. Frankly there is a lot of money to be made providing brand new services that are unreliable or quirky or ephemeral because those services never existed before.

My point is that how you test and validate your software product depends on your application. Sometimes the costs don't make sense to "run everything" and sometimes its physically impossible. I agree that you should always advocate for the highest fidelity testing your business case can afford, but be prepared to settle for less than everything and rely on your engineering skills to buy down risks in the gaps.
To be fair, the pilot said it looked like a cruse missile probably because that's the only reference point they could use.

Let's hope the US military was testing stuff and that's what it was.
I'm not arguing that the internals of an ICE motor aren't more complex. From the vehicle builder's perspective, though:

- The oil lubrication system, starter/alternator, various belts, and gearbox (if front wheel drive) are typically part of the engine package so don't really impact complexity.

- Liquid cooling is required for EVs if they're going to perform equivalently to a modern ICE car.

- EVs contain high voltage / high current wiring that needs to be considered carefully in terms of crash safety.

I'm not against EVs here, I think they're great. But if you want more than the old "drop a forklift motor and some batteries into a donor car" DIY build, an EV isn't actually that much simpler to assemble.
Given the amount of money we’re taking about, the number of investors affected and the extent of the fraud around these entities, I’m surprised we have not yet seen a securities class action suit raised against them... I suppose it’s all good while the ROI goes up. After the seemingly inevitable crash, I suspect a SCA would be on the cards
Why pay for prime retail space that's not necessarily easily accessible by car when all your orders are delivery?
Reminder that the p-value of a test is NOT the probability of H0 being true, see [0]. It only shows that, if we assume a significance of 0.05 we cannot reject the hypothesis (in our case that 89/200 is the result of a binomial distribution with p=.5).

Ask HN: What are your tips on selling to influencers?
Hi HN,

I have built an app for influencers to make more from their fans but I have zero idea on how to get them to use it. As of now I am trying cold emails and Instagram DMs. If you have done it in the past what tips do you have?
Thank you! The Raspberry Pi and a Dactyl mechanical keyboard sound like a lovely combination. If you ever decide to go ahead and build it, let me know!
We already have silicon valley sucking up all the engineers, and wall street absorbing all the math guys.

The last thing we need is a secret jewish cabal to take all the standup comedians off the market.
Great summary of the article right here.
Yeah, in the end it’s silly that we ended up with “trust” meaning only you’re connected to someone that controls the domain” which doesn’t actually need PKI to accomplish if we just supported a SRV record with the public key(s) and verifiably authoritative DNS queries.

Which fair it’s trading one PKI for another but web servers vastly outnumber authoritative DNS servers. But DKIM gets along fine without it so we probably could too.
Great project - I’ve also thought about this kind of thing.

Have you experimented with the Dasung Display much? I tried one and found it too noisy at displaying text.

Admittedly it was just connected to a Mac, but it deterred me from keeping hold of it.

Also - does ‘M-x e-ink-laptop-mode’ refer to a real thing, or is that a placeholder for something you are going to write?
You haven't met every 12-year-old. I have a daughter that fit his description, both body and mind, except she wasn't seeking a boyfriend. At 12 she was taking college classes, getting only "A" grades. Nobody suspected a thing. All her friends were much older than her, and they all assumed she was much older. This was without make-up even. Her behavior is more adult-like than that of a typical adult. She gets annoyed by the childish behavior she sees in many adults.

You might even know somebody like this. Unless you demand a photo ID to verify the age of everybody you meet, you just can't be sure.

Since there's not much of a spec (past users on newish devices), I would default to:

* Next.js - React on the frontend with endpoints handled by Next.js.

* Postgres for the DB

* Hosted on Vercel (unless otherwise specified).

* S3 for binary files.

If the project scope was anything past what Next.js APIs can reasonable handle (heavy DB migrations required, an admin panel, etc), I'd go with:

* Django Rest (or Django Graphene for GraphQL if it's a better fit) on the backend.

* React on the frontend (possibly still with Next.js if server-side rendering is high priority).

* Postgres for the DB.

* Frontend hosted on Netlify or Vercel.

* Backend hosted on Elastic Beanstalk, DB hosted on AWS Aurora, and S3 for binary files.
> "Andersen Horrowitz"? Does the author have any idea who he is criticizing or what industry they're in?

Once I saw this obvious error and realized the author doesn't even understand that VCs are different from a stock exchange, and can't even spell their name properly, I realized how ridiculous this blog actually is. His Bitcoin argument cemented it.

I want the 5 minutes of my life back that I spent reading this drivel.
They apparently buy up any competition to keep the market small. There have been other similar tech promised by startups but they buy them up. Pretty interesting! Infuriating too, of course. But the system is what it is. I'm surprised they can't make more money by cross licensing the tech and just granting royalties. I'm no economics expert though.
I worked in a food production and delivery startup (meal prep), and while I was constantly surrounded by the 'buzz' of ghost kitchens, a part of me was sure -- absolutely sure -- that this would be a fad.

Why? Simple market dynamics. After 5000 years, the economics of running a traditional restaurant are essentially identical. That's because the lion's share of the value of a restaurant is the repeat and referral business, NOT in discoverability. That's why a fancy restro-bar on Glitzy Avenue shuts down after 3 months. For a good restaurant, the CAC should go to zero over time. The food should sell itself. By adding artificial market dynamics to this equation (mandatory advertising, artificially low unit costs, artificial discovery), you are removing that crucial, critical element, and the food will inevitably suffer. Burgers-R-Us can pay $1 per customer to appear at the top of your feed, serve you a shitty hamburger, then rename to Best Burger, and rinse and repeat.

Eventually consumers will wake up (many already have), and the traditional restaurants will escape with meaningful margins. Of course only a tiny fraction of restaurants that are started turn into surviving businesses, as has been the case since time immemorial.
All of this is true except the assertion this incident is an uncontained failure. There's no evidence it was uncontained. Parts exiting the rear of the engine is a contained failure.

Personally I find it is incredibly helpful to be able to see the scrollbar at all times, even if I primarily use a mouse scroll wheel, trackpad gesture, or keyboard for scrolling. The slight bit of horizontal screen space it takes in every window is a trivial cost in comparison to the value of knowing how tall the scroll is and where the viewing window is currently scrolled.

(Note, it is also more effective to grab the scroller and drag it along the track vs. using other mouse/keyboard gestures in cases where the scroll is extremely tall or wide – anything more than about 20x the window size – and you want to move precisely to one particular part. I find this especially helpful when reading books or other long documents.)

I wish user interface designers looked for more ways to provide unobtrusive extra information in parts of the screen I am not otherwise using.
It's perfectly readable on my mobile devices. Do you mind if I ask what it's lacking on yours?
I got the official PS2 Linux kit on launch and even with the hard drive and all the accessories, it was still slow as molasses. There just wasn't nearly enough RAM to make a usable desktop environment.
While I dont care much for the fluent cutesey langauge as you call it - the error messages and consistency are where it shines. Getting an entire team to write similar error messages in test cases is a fools game - just agree on an assert library. Added bonus is the error messages can be amazing (if the lib is good).
The context is that I provided research that reached the conclusion that men were more likely to experience online harassment. You provided an article that corroborates this claim, and now you're moving the goalposts to just specific types of harassment.
The truth is that most real consumers (as apposed to us technologists) don't want e-ink technology. It is monochrome, can't do video, limited interactive due to refresh rate and ghosting... the only real thing it has going for it is low power usage. And that pairs well with applications where you spend a long time staring at the screen, and periodically initiating a compute burst to change the screen contents. In other words, e-readers and note-taking devices.

And consumers are fairly satisfied with devices that get charged once every day, and can take a 15 minute quick-charge to add multiple hours of additional usage to them.
The U2 is a very well-understood and photographed airframe. Even if given engine upgrades, it wouldn't be more than a few mph faster than before. Those big glider wings limit it to a very narrow, predictable, flight envelope.
I only took a quick look, and this source doesn't seem fantastic, so perhaps it's wrong, but anyway... here's my source [1]:

> Engine failures are defined as contained or uncontained. When engine debris leaves the engine, it is an uncontained engine failure. There appears to be a tear in the rear of the fuselage possibly from a fan blade strike. If this is the case, UA 328 suffered an uncontained engine failure.

Edit:

Yeah okay, after looking at the video in your link, I agree that it appears contained.

"Most bloggers get so little traffic on their personal websites that they see no point in continuing them, so they give up. Visit personal blogs and leave comments that let their writers know their efforts are appreciated."

Sounds like a good idea, but in practice, at scale, this is exactly the kind of functionality that doesn't work without a closed platform to take care of things. Who deletes the spam comments?
I was arguing more against the slippery slope of editorial power. I think you are making the case that it is ok because in this case it may be justified?

Personally I'm happy Trump is gone, but these are entirely different points.

Once we accept this road to be "Ok" what's next. Perhaps google starts modifying pagerank to promote content it feels better fits its politics. And again they may be justified today, but there is a danger in allowing such an instrument to exist in the first place.

>Perhaps useless in the sense that those who need them the most will either refuse to use them or misuse them.

I'd argue that such tools are valuable to everyone, even those who have no interest in verifying the credibility or veracity of information sources.

As the old saw goes, "you can lead a horse to water, but you can't make him drink." Or both more snarkily and (IMHO) more accurately, "you can lead a fool to knowledge, but you can't make him think."

>Going further... I think it might be fair to say that those tools just don't scale.

I'm not sure what your mean by "scale" in this context.

Determining for oneself the credibility/veracity of information or an information source is (and should be, IMHO) inherently an individual pursuit.
For an introduction to Unity game programming as an engineer, I can't think of a better resource than Catlike Coding tutorials:

They're great for people who are already self-sufficient programmers, and just need to quickly get up to speed on how Unity does some specific things.
> ATC didn’t call it so presumably they didn’t see it on radar.

Not a reasonable presumption. VFR aircraft are lowest priority, and traffic calls for VFRs are very much not guaranteed. If a controller has too much to do, you won’t get traffic calls. And just because the frequency is quiet, doesn’t mean the controller is twiddling their thumbs. They could be on the landline or briefing the next controller.
Thank you. That is a very strange way to look at the Earth.

Speech in the US is powerful enough to cause consequences, not really sure what you're talking about.

The US just changed administrations & congressional leadership twice in 4 years based on nothing more than ballot speech, which involved the humiliating defeat of one of the most well funded "establishment" politicians in favor of a non-politician that made a mockery of establishment practices for 4 years. Congress has representatives reviled by practically all of their colleagues and party management, yet they consistently get re-elected through ballot speech.

A series of news reports took down an entire presidency and the whole government couldn't do anything about it.

Allegations of sexual misconduct alone have sunk the careers of some of the most respected and powerful figures in multiple industries.

Protests & news reporting have directly led to historic civil rights legislation, and more recently: local council votes on police spending measures.

Sure, US politicians can be eager to censor but there are political & legal mechanisms that restrict and stop them. There is no such thing for the CCP. I've yet to see any checks on its power or speech about the CCP's atrocities & coverups affect the CCP's permanent leadership.
More likely that apple will just price gouge on a motherboard replacement and just trash the old one. And of course, they will do this only after attempting to upsell the user on an entirely new system.

It reeks of shade to intentionally grenade the hardware just to get more door traffic at retail locations.
> If Apple needed a public contract for open operating systems to build on top of, it would either slow down the roadmap, or break the open software regularly

They managed it with Boot Camp itself, so it can be done. Also, forcing alternate app stores would be even more of an impedance in the vertical integration model.

That said I don’t think the forced boot camp is a requirement.

Agreed about Google. Google said ‘open always wins’, and then Android didn’t win because it’s not actually open.

It already is super easy for consumers to have access to “something else” vs Apple. It’s just that the only viable “something else” is Android, which isn’t open. Consumers need an open alternative to choose before they can actually choose it.

> It isn't just a money problem, it's a technical and human coordination problem that can't be solved with money.

Building an open mobile Linux problem is both a human coordination problem and a money problem. Not much different from Ubuntu or Firefox, just with a different goal.

You need a coordinated group of people and they need to be paid to work on it full time.

That can definitely be solved with money, as long as there are people who want to build it.
A car accident occurred down the street from me the other day; I heard it, and there were eye witnesses, but there was no video.

I guess it didn't happen.
This looks like it was a contained engine failure, even though the cowling fell off. A portion of a fan blade was embedded in the containment ring and the other damaged blades is missing but probably went out the front, slicing the cowling on its way.

There's an implied right that the goods are fit for purpose for their lifespan. I don't think a lack of security because they stop offering /any/ updates at /any/ price is resulting in machines fit for purpose.

Updates should last as long as they say on the tin (eg "the lifespan of this laptop expires in jan 2022") when you buy it and it should be noted in bold that the machine should be considered unusable after that date.

It’s an understatement, not a stretch.

Heroku has always seemed really interesting/cool/clever to me. The tradeoff has never been worth the investment when I’ve considered using them, personally or professionally. Their operating model is far too different than every other cloud provider’s.

Which companies / patents did they buy up? I keep seeing this rumor floating around but their Wikipedia article lists exactly one acquisition (https://en.wikipedia.org/wiki/E_Ink#Acquisition) and a casual Google doesn't show any others.
This is Li Zhi's wikipedia page: https://en.wikipedia.org/wiki/Li_Zhi_(singer) for those who are curious, basically this is a repo linking to his music so Chinese programmers in China can still access his music, he is pretty much blocked all over Chinese social media, music streaming and cloud storage sites. He has also pretty much been "exiled" or "harmonized" from the public eye.

The PixelQi display spun from the OLPC project was really good and clearly affordable, considering the original target market. Granted, E-ink is superior in many aspects, but I'd settle for a sunlight readable, low power monochrome LCD display. As an added benefit it updates much faster than E-ink.
