If you've ever used "Bayesian optimization" to choose hyperparameters, that was almost definitely a Gaussian process.

The article focused on the case where you have a finite number of test points, which is probably a good idea for an article like this. Still, there is another interpretation of Gaussian processes where they are actual stochastic processes (hence the name), a probability distribution over a set of functions.

I would have found an article that covered that interpretation even more helpful, although I'm not sure an easy-to-follow version could exist.
The US optical market seems bizarrely uncompetitive. Here in the UK, you can buy good quality prescription glasses online or in-store for less than $60. You can get a serviceable pair for as little as $25. Warby Parker's pricing simply wouldn't make an impact over here.

We actually did this. When I started at Uber ATG one of our devs made a submodule called `uber_monorepo` that was linked from the root of our git repo. In our repo's `.buckconfig` file we had access to everything that the mobile developers at Uber had access to by prefixing our targets with `//uber_monorepo/`

We did however run into the standard dependency resolution issue when you have any loosely coupled dependency. Updating our submodule usually required a 1-2 day effort because we were out of sync for a month or two.
Tesla will produce close to 400k cars from one factory in 2019. It is now (relatively) easy for them to reproduce that with all their learnings in additional factories around the world.

They also own an energy and solar branch of the company which have huge growth potential and run their own electric (gas) stations.

Mandatory security rules which boil down to client isolation. Clients on the same network can't talk to each other because security fears that.
There's a lot more to towing than just the curb weight of the vehicle. For example SUVs with CVTs often have lower towing capacity than the same SUV with a normal automatic transmission even though they weigh the same.

There's a lot that goes into making a vehicle good for towing, and a luxury sedan is not normally expected to have a good towing capacity no matter how much it weighs.
My suburban city is the same and I drive, walk or bike everywhere. Estimated travel time for going by bus here is .. identical to that of walking, according to Google.

But that makes the "transit is for the rich" argument rather, uh, rich. Transit is for the rich ... now. Make a decent bus service and it wouldn't be.
In other words, basically treat the driver initialized to talk to the client-device the way mobile iOS treats apps: start them off with no capabilities, and then make them ask the OS to prompt in order to get persistent capability tokens granted.

I'm a long time friend with Pablo, the main researcher behind this discovery, since our time together at the university.

Every time this pops up there is some comment dismissing the discovery as yet another graphene theoretical breakthrough with no practical application. This discovery can help us better understand superconductivity at high temperatures, and that along will qualify it as a major discovery. It can also be super important in practice if we manage to bring graphene out of the lab.

Not everything hits mass market in a 5 years timeframe... in the short term it may seem we have a slow rate of adoption of new technologies, but if you take a step back you can see the rate is fabulous. Graphene, batteries, solar cells and before them, transistors, nuclear power, etc. may take a while to hit the market, when they hit it they hit it hard.

> photos of a 20 mile object whilst flying past at ~8 miles/sec

Not to detract at all from the astonishing technical achievement, but that's the wrong comparison. You can see the ISS with your naked eye, and it's a <1 mile object flying past at 4.8 miles/sec. The right comparison is with the distance at which this photo was taken: 18,000 miles, or about half an hour from closest approach.

Actually, the right comparison is of the closest approach distance (~2000 miles) with the distance from earth (4,000,000,000 miles). That's like launching a missile from Los Angeles to New York and hitting your target to within a meter.

You have an a bit cached but true point, that's is: there was a so big push to web tech that actual local graphics libraries was left in an old era without real updates. That's the case even of Qt and their QML mess. That's the case of GTk mess etc.

However have a browser as a framework and environment for anything is even worse than actual X server architectures.

So yes, we need to rethink desktops, perhaps looking at past solutions like LispM GUIs and Plan9/Rio but certainly not move toward actual trend.

In the vastness of a universe as large as ours, polka dotted unicorns are probably very likely. But it's still unlikely to actually encounter one ... you know, because they're polka dotted unicorns and because the universe is so big...

I can trust a public outlet to not fry my phone. That is simple, if my phone stays functional I'm good, and if it gets fried I take some real world measures (go to small causes court, make a denounce to some government agency) to get compensation.

The real problem on public outlets is with data attacks, not power. If I can set my phone to ignore all the data at the first hardware level, and it is a simple enough level that no attack is viable (that second one being a large "if"), then there is no large problem anymore.
>Problem is that the same homeowners who brought you Prop 13 also want to keep getting places by car

As I've said said so many times before, every nation gets the government it deserves. Americans don't want bikeable or walkable cities, so we don't have them. Europeans do want them, so they have them.

>In some European cities, the bicycle is its own form of transit, and it can likewise be that because separate bike paths exist that complement the walkable structure of those cities.

Yep, I was in Germany recently, and the large cities I visited all had excellent subway/train systems, as well as bike paths on all the major roads. And unlike bike lanes in US cities, the bike lanes were on the same level as the sidewalk, physically separated from the cars. The cities themselves were far more dense too: not as dense as Manhattan, but still far more dense than your typical American suburban "city", so it was very feasible to get around by bike and subway and also tram (electric streetcar).

We're not going to de-prioritize the car because Americans just can't think that way; they can't stand the thought of having to share space with strangers. So we're going to continue building more roads, and getting worse and worse congestion. It's not ever going to get better, because generally, when you look at the history of human societies, things rarely get fixed before there's a total collapse or disaster of some kind. Humans in groups just aren't smart enough to avoid disasters even when they're plainly obvious.
It's worse than that. We now have a situation where different cables of same connection type can damage hardware (as we've seen with powered USB-C hubs and the Nintendo Switch with some 3rd party chargers and docks, etc).

It used to be the case that anything of the same connection type would - at worst - not work if it wasn't designed for that piece of equipment. But now you have a situation where things "kinda" work together so consumers are encouraged to mix and match yet some of the time it could literally break your hardware.

So now we have a situation where some people are too scared to mix and match which breaks the entire point of a standard connection type - and on the flip-side you have other people who are left with bricked hardware because they were unlucky enough to plug the wrong charger with the wrong device (for example).

You've seen plenty of compelling uses for blockchains it's just that you haven't seen any which could only be done using the blockchain.

I always think about the blockchain as TCP/IP with history. Plenty of value in that.
You also have to account for the amount of work it once took, and the mindset that creates. It's another domain entirely as a result.

The fact that Audacity or GIMP exists at all and was free was shocking to a lot of us. Programming audiovisual stuff competently took knowing the CPU on a machine-code level if you wanted to get a usable program (and wanted clients to be able to get something done in weeks, not months) and the idea of doing all that work for free would just get belly laughs from most folks.

There's a reason the highly optimized stuff still costs hard money, and it's not due to hubris.
They are. Any gas tax is a tax on the fuel economy of the vehicle. If pickups get less MPG, they are taxed more on gas tax. Some US states base vehicle registration fees on the weight of the vehicle, which is another tax on heavier vehicles (like pickup trucks). More damage done in accidents is something the insurance companies would have to deal with, and if it's actually a problem you can guarantee those insurance companies have already factored it into the rates.
China launches human voice Mongolian speech synthesis system
I feel like there is a connection between the functional programming (FP) that logic circuits do, and the imperative programming (IP) of languages like C, through parser generators like YACC. In other words:

(FP) Verilog/VHDL<->YACC<->C (IP)

I have seen many FP to C transpilers (where you write the spec in a FP language like Lisp and it generates IP language C) because it's trivial:

https://www.quora.com/How-can-I-compile-a-Common-Lisp-or-Sch...

But I've never seen a C to Lisp transpiler that breaks the code down into a series of basic functions. My guess is that mutability becomes a major problem and either can't be represented without monads, or becomes unreadable spaghetti where the mutations have to be expressed via types or generics somehow.

In other words, the difficulty of statically analyzing mutability leads to excessively complex FP code that is unreadable by humans.

This might be one of the only examples I've seen where someone went from relatively human readable C to the FP expressed in the circuit by way of YACC.

Edit: upon reading this again, it looks like only the input equations were parsed by the "YACC generated program". The C code was only used for the "event driven cycle accurate simulator". But I still think there is merit in what I said about FP<->YACC<->IP.

Intellectual property rights aren't holy scriptures. Not every right should be respected and it seems dishonest to play that card. It's the same idea as law isn't moral just because it's the law. It can still be unjust and immoral, depending on the circumstances. To follow a hard line of always adhering to the law without any regard for the consequences or context can lead to bad outcomes.
I'm honestly somewhat surprised that you-know-who is asking DP problems with that degree of complexity. Are you applying for a research/math-heavy role? If you're unlucky enough to see DP, usually it's pretty basic and memoization is considered fine, unless things have changed very recently. If they required that degree of rigor for regular SWE jobs, a lot of people I know certainly wouldn't be there.

I don't think X509 or public key crypto is as scary as it looks, once you understand what you're actually dealing with and how the openssl related libraries work.

There is definitely a UX issue though, and—without intending to be disrespectful—junior devs coming into programming through Javascript, or building basic microservices, are going to see a lot written about JWT and how easy it can be to work with, and suddenly JWT is the solution.

The API for JWT in most cases is encode/decode, and you provide the payload, the options, and the key. The API for libraries linked with OpenSSL is typically a lot more verbose, so you have to understand what you need to work with, or how you might need to extract a fingerprint, convert to DER, or whatever.

Beyond that, a lot of us in the web world might associate X509 with SOAP and XML, and plenty of people will avoid XML at all costs by virtue of it being XML. There's no reason why you couldn't use X509 in a JSON payload.
Kona will only be available in a small number of U.S. states and global regions, in limited quantities.

It is a compliance car, to reduce the emissions overall of the fleet they sell allowing them to sell more high profit ICE cars. They are likely losing money on each sale as well.

I think the Kona is a great start and wish it would have a better chance, but it is crippled from the beginning.
Not true. Healthcare service costs in other industrialized countries are much lower than the US, because of their better systems. So, for instance, if you need hip replacement surgery and you have to pay for it out-of-pocket, it'll cost you a small fraction if you get it done in Belgium than in the US.

That whole Atlantic article is predicated on the main cost of a ride being the driver's time. Get rid of the driver and you get rid of that cost. Get rid of the internal combustion engine (which has large economies of scale - one big engine works more efficiently than many small ones) and you lose the fuel advantage - many small electric engines are just as efficient as one big one.

The boarding issue in the article is mostly in reference to the driver's time, but there's a simple solution for the rider: docking, not board. Board a pod once, at your door, and travel inside it until you reach your destination. If you need to switch modalities - like latching a number of pods together into a train for long road trips, or putting them on an aircraft - you load the pods onto the plane, you don't transfer the people between pods. It's like intermodal containers for passengers, with the nice benefit that you can continue working on your laptop or watching a movie or sleeping throughout modality switches.

I'm not defending get-rich-quick scheme peddles, but charging for lessons in how to make money doesn't prove the lessons are bad. Nobody says this kind of thing about how new software textbook of the week must be wrong be wrong because sharing it hurts the author's employability and they're charging for the book so it must not be a desire to share.

There are plenty of ways to make money that aren't zero sum competitive markets. Some people want to share what they know and aren't hurt by it. But writing that stuff up costs time and energy, so charging for it makes sense.
Renaissance Technologies (the hedge fund) is the classic example of someone who "has a winning system". Funnily enough, they don't share it, indeed, they guard it zealously.
Buddy, client isolation mode or lack there of is sometimes called allowing 'peer to peer' traffic. I understand the ambiguity over TCP P2P networks, but given the context most network engineers know what you are talking about. Regarding the article mentioning multicast -- the engineer SUSPECTS its to do with multicast. Im saying it could be due to several configuration issues, but most likely client isolation mode (aka not allowing peer-to-peer traffic). Why pick a fight over this?

I don't follow your logic here. With the reduced tax incentive, Teslas have seen an effective increase of ~$1,750 USD.

Would you normally argue that a yearly price increase of ~3% on a car portends anything in particular about demand? I guess it implies that they expected demand to fall if the increase had been ~6% instead, but that doesn't seem like anything that would preclude 50% worldwide growth.
