I can confirm. In one of my interviews, when writing Python, I used arr.push instead of arr.append (I don't usually write JS, but idk what happened), and I realised the mistake only half-way through. The interviewer noticed it apparently, and he said he didn't care. I imagine he didn't want to throw me off my thought train, which was nice. Got the offer too, so it really must not have mattered.
Sure, but if you buy a rice cooker, maybe the ads to show you are for: rice, cookbooks (featuring lots of rice?), pressure cookers, cast iron pans, sous vide recirculators, and so on. I mean, you have a rice cooker, you won't want another, but chances are you'd buy other things you don't already have.
I think the FT is biased in favour of free markets and globalisation.

The example that comes to my mind for "loss leader" is stores a while back selling CD-R spindles for almost free, limit one per customer, to get people in the door. No lock-in at all, just a way of doing advertising.

It's the hydrogen that makes it a hybrid. The parent comment is correct. Being a hybrid does not require eg a gasoline motor. It's not strictly an electric vehicle, it requires hydrogen in the process.

Their own diagram is very clear about this matter: motor + fuel cell + hydrogen + battery.

Even if Tesla can themselves manage the logistics, it's certainly a negative for potential consumers, especially second+ owners. Maybe Tesla will offer a VIN lookup so you can find out what a particular car's specs are while you're shopping.
What is different — generally — between the way Amazon determines prices, in your example, and the way Google determines the best search results? It seems they both use massive knowledge and technology advantages to determine something that’s in the best interest of the company...

In fact almost all large businesses use these types of data to maximize profits, I would assume. Is there a functional difference between changing a digital page to optimize return and changing a store shelf configuration at Wal Mart to do the same? Because of course Wal Mart uses analytics to determine their store layouts and deal placements etc.

In this case, I mean a subsystem that has been in production since 2006 and has been processing hundreds of thousands of messages a day. I don't claim that it's perfect or bug-free, but if it had significant memory errors I'd have heard about it. I designed and implemented it to use patterns like RAII to manage memory, and it's worked quite well.
Unrelated, "The Inner Light" episode still hits me in my soul, even after all this time. For those that have not seen it, you owe yourself to watch it.
Woah - a huge flash to the past when I read this.

I ported Wayland to VideoCore4 (the multimedia engine in first Pi chip) back in 2011 - it was part of the Meltemi Nokia project that got cancelled the follow year - shame as it was pretty cool and had half a chance IMO. We worked with the team in Oslo on QT acceleration over GL ES and used EGL below Wayland (coupled with some magic APIs to get the VideoCore HVS to work well). Ported this to an ARM combo chip that had just the VideoCore GPU in it as well (no HVS) - it worked pretty well.

Prior to this however, I made a VideoCore demo that used a PCI bridge chip (from Broadcom) and you could plug it into a Dell laptop running Ubuntu and get accelerated video decode and also X11 window scaling working at 60fps. We nearly sold this into Apple for accelerating their macbook's but IIRC, getting the macbook into low power mode whilst the video was playing on the external chip was going to be soo much work that they gave up.

A even further back, I remember validating the HVS hardware block and writing the initial scaler driver for it (IIRC, scaler.c...) and made a dispman2 port for the driver. Circa 2006!

Great team - one of the most enjoyable set of people to work with I've ever come across.
What is the ratio between people who viewed a rice cooker (the group I'm assuming they target with ads) vs. those who actually bought a rice cooker?

Is it possible the ratio is so large to where while it obviously could be optimized to exclude people who have since purchased said item - the optimization is only a rounding error, and may not turn out to be worth it?

>Nine times out of ten a candidate scores low because they overlooked an infinite loop or code would crash on boundary conditions and candidate wasn't able to realize that even with hints.

I guess this depends on how you run the interview but one of the things that frustrates me about whiteboard interviews that focus on the coding rather than the design is that I have to step through test cases (especially edge cases) like this manually, which is tedious and not at all how you do things in real life, where you just run the test cases and see what happens instead of having to run your own code on a whiteboard.

It's interesting you brought this up, because it's the same thing that happened to the music industry with piracy. A decade of rampant piracy changed the mindset of the consumer to value music at $0.

Almost all of the musicians I know that were able to make a living without a major label, before 2000, all could no longer make a living. It really hurt the independent artist and only made musicians more reliant on big labels.

The same thing would have happened to the software, but many companies moved to SAAS.

Is it any worse than what other manufacturers deal with? The 2019 Honda Accord shares some parts with the 2018 Honda Accord which shares some parts with the 2017 model... when something breaks in my Honda the first question is "do they still make/use this part or did they change it in newer models?"
My main rule is "no naked new," meaning that the only place the new operator is allowed is in a constructor, and the only place delete is allowed is in a destructor (unless there's some very special circumstance). This style lends itself to RAII. The other rule is to use the standard library containers unless there's a very good reason not to do so. That seems to cover most of the really basic errors.
I built a house with no walls, and then someone stole my TV!
Right.

Also, sometimes you want to leave things undefined. This killed the attempt to create a formal specification for ECMAScript 4 back in the day. For example, it was hard to formally specify things like "Array.sort calls the sorting order callback in such a way as to make the array sorted" without mandating a particular sorting algorithm.
Would that happen to be Charleston? 10 years ago, a friend from South Carolina thought about doing an apprenticeship in custom furniture there but decided instead on his other dream job and became an Indy Car racing mechanic after completing a year-long course in the Jim Russell school up at Sonoma. He still talks about possibly getting into furniture, though.
I wouldn't be surprised if the actual reason was they are capturing extra sales from people who bought something, liked it a lot, and then bought another to give to their kids or for their second home. My mom buys me random chotchkies all the time after she bought them and liked them, and if my parents were well off I could easily see her buying me a vacuum or a new mattress after she got herself one.

For 99% of people that probably doesn't happen, but the people with the money to do that probably spend a TON of money, so they are worth targeting with ads.
When I've read about flipped classroom, a lot of the instruction is described as teachers working closely with students, given the importance of individualized instruction. However, that does also result in a lot of solo learning.

If the teacher is working with 25 students for a 50 minute class, that's 2 minutes of individualized instruction per student. Even with the students working with the teacher in groups, you're going to have a lot of students working alone when they're not working in the teacher's group.
The likes of the FT/Economist etc seems to scale well because it has an engaged audience that is used to paying for it and sees the value in paying fOr news.

Gee, I hope they have some kind of system to track that. Maybe software even?

No, it's not. All of those companies are extremely averse to putting boots on the ground, preferring software solutions instead.

As I understand it, the permanent magnet motor is more efficient at low fractions of maximum torque/power output. So, when cruising, the rear motor will be powered down. When accelerating heavily, the rear motor can kick in.

You know it took me a long time to understand this part of human nature and social interactions. And I believe it's one of the deepest force behind all the technological change and society evolution. We want to be able to do more without feeling indebted to someone. Today it's reached the point where we almost don't want to owe a hello to a cashier at McDonald's. We want to deal less and less with the potential randomness of people.

I believe we're doing away with the art of trust and replace it with a computerized world.
I want someone to write some analysis of this particular... voice, or style of writing, being used here.

"I'm a web guy. I’m not a farmer."

I already knew that, because in just a couple paragraphs, I was already recognizing the style of writing as... SEO, "influencer", I don't know what to call it?

It's a personal first-person voice, which right off the start tries to establish that the author is a human being writing about their life -- but also that they are an expert in what they are going to tell you about, and very successful too.

The text includes many one or two sentence paragraphs, and has aggressively styled pull quotes and/or callouts. Short sentences too. Not entirely complete sentences. Interspersed.

It makes sure to open up with some kind of very short story that is only tangentially related to the content but is folksy and cute. (Smuggled vidalia's onto cruise ship).

The information is very cleverly structured to keep you reading, by dropping just enough of the actual info, page to page, to pique your attention and make you think there's an interesting story here, but not enough that you can leave having actually learned anything before you've read a pretty big chunk. And is written artfully for this purpose, it works, and keeps you reading. Sometimes at the end you feel rewarded, other times you feel like it was a shaggy dog story. The best authors leave you happy, of course.

It's got information to convey, but the goal is not to convey the information as effectively as possible, but to keep you reading as long as possible -- and, usually, to sell you something.

I don't know if I have a value judgement on it exactly -- okay, I'll admit it annoys me, perhaps because it all sounds the same while trying to convince you it's a folksy authentic voice. But either way, it's a thing, a genre even, that I'm not sure I've seen anyone comment on.

It's: "Content Marketing Voice".

(Also selling people onions on the internet is "purpose over profit", really? What the world needs now is frictionless access to vidalia onions shipped directly to your home?)

Podcasts are talk radio on demand. If you're against podcasts, you're against talk radio. Or at the very least, you're against making talk radio more convenient and accessible.
So it sounds like the range increase is for new cars? (Other comments made it sound like a software update to existing cars)

I still wish there was more focus on range over acceleration, obviously electric motors don't suffer from general efficiency impact as ICEs do (an ICE with superior acceleration seems to take an efficiency hit at all speeds), but how much of that "faster acceleration" impacts efficiency over the course of driving a few hundred miles.

It's a pretty interesting example of the pitfalls of ML. It's a clever and exciting use of ML and when observed in a silo is the correct thing for any company to do. The law wasn't designed for such sophisticated modelling of the domain. Screwing over small and medium businesses was never the goal, it's just an inevitable consequence. The flip side is the algorithm cannot model what happens once they screw over businesses so badly that it causes a mass migration away from Amazon (because they've not seen that data before). Fascinating to see how this plays out.

That is the hardest part, and all that matters. Anyone can make one concept car. Not everyone can make hundreds of thousands of them per year.

On the preface of the book (omitted from the ebook), it details several learning paths:

The Classic: a basic database theory course covering the classical material would center around Parts B and C. Chapter 10 and parts of Chapter 9 of Part C are somewhat more advanced and could be skipped. If time allows, some of Chapter 12 and a selection of Part F might be covered.

Feast of Query Languages: a course on the theory of query languages would start with a quick review of the basic material on classical languages (Part B), and continue with Parts D and E. If time allows, some material on languages for complex objects and object-oriented databases (Part F) could be covered.

Gourmet Sampling of Database Theory: a course for people with theoretical appetites that emphasizes the specificity of database theory. Logicians wishing to explore the connection between finite-model theory and databases will be interested in Parts C and E. Those interested in descriptive complexity will find Part E closest to their hearts. Researchers in logic programming will prefer Part D, particularly Chapters 12, 13, and 15. People with a background in theoretical artificial intelligence will find Parts D and F of particular interest. Rule-based systems are related to Chapter 14 (see also parts of Chapter 22). Programming language people will be interested in much of the material on query languages, including Chapters 20 and 21 in Part F.

Fast-Food Database Theory: a course for applied database students that is meant to provide informal exposure to some of the basic results of database theory. This would include assorted topics, with an informal presentation emphasizing the examples, results, and intuition provided in the text, rather than the proofs. A possible syllabus would include Part B; parts of Chapters 8, 9, and 11 in Part C; Chapter 12 and parts of Chapter 15 in Part D; and selected chapters of Part F.

Numerous exercises have been included, and they are essentially of three categories. Routine exercises (unmarked) require easy manipulation of the basic concepts and results. Harder exercises are marked with a (*). Another category of exercises is meant to complement the material in the text and often contains results from related research articles. These exercises are usually on the hard side and some may constitute term projects. These exercises are marked with a ( ).
This is good. It's Tesla focusing on making better cars. More range is good. Faster charging is good. Those are real things.
Yesterday's claims about Tesla operating a million self-driving taxis by 2020 were, well, not taken too seriously.

The new stuff is all at the high end, though. The $35,000 Model 3 is still absent from the product line.
Not surprised. They can't expect people to replace their car every two years as if it were an iPhone.

I feel like that's a very naive way to look at it.

Lots of entities have enough capital to get a news company going, the problem is profitability and long-term sustainability. Not to mention running an actual news agency. Just because a company is profitable in one area doesn't mean they're guaranteed success in another.

How are companies like Facebook supposed to solve this problem? Where is the money to pay for these journalists going to come from? The ad revenue generated by that wing of their company? If it was that easy, then existing media companies wouldn't be struggling.

If you're counting on there being synergy between their existing userbase then I don't think it's worth it because there's so many risks. If a company starts pushing a certain type of news, their credibility and their brand would be so closely tied together with their news branch that either the news would be very bland and have a n agenda while also potentially alienating a large portion of users. This could very well lead to killing their main product.

Companies like google are already under fire for being partial. Add in them actively writing about things like politics and it'd be like adding a barrel of oil.

Not to mention the anti-trust laws involved. Companies like the ones you mentioned are already overpowered let alone giving them the keys to present actual news.

I read somewhere (can't remember exactly where) that this happens because people are most likely to buy the same item they just bought due to not being happy with their original purchase.
AFAIK that's pretty standard for most manufacturers. I can look up my SUV's VIN online and get its full configuration.
You have a point and I forgot to add that above.

I had many motives. I'm annoyed at society race for new and shiney when you don't have to. It was part of the reason the interaction wasn't super neat because it was a bit of a foggy subtext. Now it wasn't all, I wanted to show her what was possible with her machine, and relieve her of stress. But it's true that when we spend time with people, the faster you make sure there's no hidden agenda from your side, the better. I believe if your mind and heart is clear, people will follow rapidly. It's a trust issue.
I would expect that the type of attention is important. In meditation, when first instructed to focus on their breath, a lot of people alter their breath patterns. The practice is getting the attention that rests with the natural breath. Then knowing the quality of that attention, it's possible to see other phenomena without interferance.

My guess is these runners didn’t have this attentional skill.
You're right, they don't. But it's not about physical newspapers, it's about journalism itself. Journalism itself is not being funded. This is partly because internet platforms/adtech have broken its financing model. Of course it's possible for the ideologically-minded to counter this by donating to journalism organizations for their public service, without turning to the public sector. But people obviously aren't doing that (enough).

The reality is that individuals often don't think in terms of a big enough picture to support abstract public goods with private donations. Capitalism would say "good, people apparently don't want those things, let them die". But "people don't think about it" and "it doesn't have value" are very different things.

Is it just me or does the engineer to non-engineer pay ratio seem unusually low?
To be clear, my suggestion was that they should put boots on the ground, not that they should employ bots or ml. There are journalists looking for work and there are media companies with more money than they know what to do with. Facebook could hire local journalists.

I know they won't, because they don't care about the quality of content on their platform. But there's no reason they couldn't hire actual journalists to do actual reporting for their platform, except that nobody is demanding it of them.
