Disagree. This feels more contemporary and integrated.
Remember that much of what is sold on Amazon.com is not actually sold by Amazon. Amazon provides warehousing and fulfillment and an online storefront for third party sellers as well as for itself. The tools that it uses to run that online storefront in the form of AWS are used by many non-Amazon websites as well. The Kindle ecosystem helps Amazon sell retail books but also provides a self-publishing platform. It's not unreasonable to say that logistics, warehousing and web services are the real business, and that Amazon's retail business is one of many customers.
I'd just be happy if they put all those people back on the Mac and OSX team.

One of the most valuable skills I always try to teach junior (and sometimes not so junior) developers is not only how to abstract your problems (as the author points out in this article), but also how to follow a related chain. For instance, let's say you have an issue with some event not firing in an old browser, and as you research it, you see the same answers saying a concept you haven't heard of before. Looking that concept up (and either reading about it or following some tutorial) then teaches a wider understanding in that domain, instead of a bandaid fix that the developer doesn't understand but fixes the problem now.

The role of a developer isn't just about solving problems, but to understand why the solution works as well.
In the US, ~45% of car registrations are new vehicles. In 2016 around 17.6 million new passenger vehicles were sold in the US with a combined transaction price between $500B and $600B.

That puts used car sales (including private sales) at around 22 million units, and nearly 40M total cars sold and registered in the US in 2016.

Regardless, if someone wants to complain about expensive classic cars, Porsches aren't the ones to complain about, with most (bulk being 911s from '78 - '93) trading hands well under $100K (964s being more like $50-65K, SCs more like $20-30K) despite the Porsche bubble that's been growing for a long while now -- since Ferraris long ago got too expensive for first time classic car buyers.

Not many, certainly. Which is perhaps why it's better for this to be implemented (since differential privacy is a known, rigorous definition for privacy), rather than to leave it up to the larger majority of users who (by your implication) don't understand it and won't be bothered to understand it.
Once upon a time I set out to just build a startup fueled by ambition. I designed and strategized, e.t.c basics of the product, but I always found it hard to find a (technical) cofounder despite talking to friends.
After learning to code and realizing how much work (& burnout) I'd have to put in before this takes off, I opted out knowing I wasn't trying to make a product users want. A proof of that was the difficulty in finding a cofounder despite having skilled enough friends.
I got into depression. As I opted out, started learning the process of creating products that actually have real users wanting. I read carefully all of PG's essays, used Headspace for meditating & focused on good diet.
The most important lesson was about fixing broken problems in your daily life. Now, I'm working on a new startup with 2 other cofounders who are actually passionate about what we're building. We have alot of feedback/subscribed users and safe to say, we're on the right track.

I guess the idea of 'think big' is just wrong. Young folks get pressured into 'making it' that they believe thinking big would solve your problems/make you great. That's what I experienced. Don't think big, focus on discovering the tiny little things - the ones broken, and fix them. That's joy enough for a Hacker.

Because intricate things with downsides that are difficult to understand is exactly where legislation can protect consumers.

The whole 'if consumers care' thing is kinda bullshit. They simply don't have the time or ability to get into the details. It's even more of a problem when companies train users to just accept changes to agreements, so they can keep using a physical device that sits in their home.
> When I investigated it, there seemed to be no way to actually connect a repl to a running program.

i (poorly) implemented conditions for racket once, including the ability to drop into a repl at the point of error.

so i think you could put in place some macros that would let you get at a repl wherever you wanted. probably not the sort of thing to leave in place all the time, though

> Unlike with common lisp or clojure, with racket if you make changes to your code you have to restart the REPL, which destroys your state.

that's a different issue. i believe matthias has commented on the mailing list (some years back) that the semantics associated with doing something like that are a mess, and that's why they weren't interested in implementing it.
IMO you do have a good point: Nothing about Prime seems to play particularly to Amazon's strengths, other than the wide reach of their sales channels (but if that's an argument, you could as well have Walmart doing the same). This is especially visible when you compare their software to Netflix. Still light years ahead of Apple though.

Replacing half of all driving is still a world changing benefit to society.

The self driving technology that already exists could change the world with regards to the trucking industry alone, as trucking hours are mostly done in "easy" conditions on the highway.

Trillions of dollars will be saved even if self driving trucks only ever work in sunny weather on the highway.

>In fact you'll find more people of interest by talking to them rather than filtering by outward appearance.

...at the cost of time/effort. Of course you'll find more people by removing a filter that isn't 100% correct; you'll just find more noise too.

I've never understood "don't judge a book by its cover"; the alternative is to read every single book? If your metric is decent (and being corrected over time), then judging should drastically refuce your rate of false positives. Assuming the 90% rule, finite time, and sufficient resources that even with lots of false negatives there'll still be enough books (or otherwise) for you to go through; then not judging by the cover is a massive inefficiency.

You're just doing a naive brute force search by not filtering by the cover.

The problem occurs when your policy is strict, not that it exists.

And its pretty difficult to imagine that aesthetics aren't a useful signal to watch for, unless you simply aren't paying attention; very few communities don't construct their own slang, attire, quirks and what-nots. Even long-standing groups of two or three will do so. And few are skilled at hiding it. So you can get at least some indication of a person's background and interests based off their behavior and clothing; they question is if you can get enough information to construct a useful filter from, and that's partially dependent on your own awareness of various cultures, your ability to detect and the actual information available from this signal.

It seems like a huge jump is being made from a hypothesis to interpretation of data. Has the connection between HRV and the body's preparedness for exercise been tested in repeated experiments?
A 2008 TechCrunch article has an uncited blockquote about it [1]. From that verbiage, it appears it's H.264 produced with a good encoder, likely some custom quantizer matrices (vs. the default flat matrices, to allocate less detail to dark scenes and more to brighter scenes), less aggressive deblocking (to reduce smudging and impart 'fake sharpness'), ABR-like capped VBR -- similar to bit-reservoir MP3; multi-pass encoding, some tunings for film grain preservation (or emulation?), and maybe a sharpen filter.

If you've ever used x264, all of the above techniques are common advice to encode film material, except for the use of multi-pass encoding, which is being used by Vudu to make the file more CBR-like in the beginning, and gradually attain VBR.

That last point you make is very PGesque. IIRC, he wrote that the truly good problems exhibit pants-on-fire demand amongst a small number of people, and are therefore at first generally very niche. I think he even said there's usually no way to predict if you'll ever break out of that niche.

This idea comes up a lot, but it is based on faulty assumptions. First, time parsing HTML is irrelevant compared to network latency and even DOM and CSS work that browsers do. Second, a parser that handled only, say, strict XML would certainly be easier for the parser author to write, but it would be slower than the optimized parsers browsers already have for HTML. If optimized, it still would not be significantly faster than a full HTML5 parser.

Your idea wouldn't work because it would never create any noticeable impact on page loading speed even in the best case scenario. That's assuming that browsers want to maintain and ship two totally different parsers, which (cf. XHTML) they don't.

To me, being able to make changes to your code while keeping the current state in the REPL is key to interactive development.

My workflow is generally to build up state, and then experiment with functions on that state until I get the correct output.

This workflow is very natural in Clojure, Common Lisp and even Python (with IPython and autoreload).

However, in Racket you have to restart everything on every change. This works ok for smaller applications, but if for example, your state is a large dataset that you pull from a remote database, it becomes a little more difficult.

There are possibly workarounds, and I'm not saying that Racket is bad because of this. There are definite advantages to this approach, mainly for keeping everything simple and predictable. However, this was a roadblock for me, and the main reason why I didn't spend more time working on it.

I also miss the ability to make changes to code, refresh the browser and instantly see the changes (instead of having to restart the server after each change).

Here's a good discussion (in my opinion) of what makes a good REPL for interactive development:

I don't see an issue with extension headers in IPv6. The RFCs have rules on who should look at what header and what to do when an unrecognized one is encountered.

Most firewalls I've dealt with have some option to defragment the inbound packet at the firewall so that the rest of the rules can be processed properly and to protect nodes from malicious fragments.
> I generally agree with this. Tutorials are most useful when they illustrate the building blocks for larger problems, and when they explain the why along with the how.

This is a big issue I have with a lot of microsofts documentation, they describe the steps in great detail (click this, type this, click that, right-click here) but will often completely skip they why. It's like every tutorial is for complete novice level developers. As soon as you have to do something that veers slightly away from the path you are back to square one.

Apple doesn't build small computers. They design consumer technology.

Someone else builds it.

They need to avoid institutional imperative by finding something other than small computers, which is facing stiff competition from emerging markets.

Before they just made laptops and desktops. Then handhelds. Now watches and tablets.

That's three non-trivial pivots from what someone in 1999 might call Apple's "core" business.

Sometimes something just seems too much and so you back down. But they necessarily have to keep looking.

People write software. Standards come later. Your standards zealotry is blinding you to how software development gets done and how the Web really works.

You are calling "indefensible" the way the entire industry actually works. Maybe you want to step back and look at why that happens.

Creating beginners at both is important though, as is helping to encourage self-directed learning.

Everybody and their dog is trying to develop autonomous tech and license it. Autonomous capabilities used to be regarded as the secret sauce, and if you had it, the future of mobility was yours. This is not true. The ability to mass produce a vehicle is the secret sauce. It's the part that's hard to do.

But as far as low margins in the car industry goes, that point is irrelevant. Robotaxis are a different ballgame.
I second this. I've been using various squeezebox devices (and software players) for years, for both listening to my own music collection as well as streaming (spotify mostly).

There are also open-source software clients readily available.
