How do you control for people's abstract desires not mapping well to what they actually want?

Example to illustrate my point: Focus groups over the past 15 years or so have consistently told car mfrs that consumers want larger cars - larger cars are assumed to be more luxurious and associated with financial success, and thus are desirable. The end result is that previous small, manoeuvrable, city cars are now bigger and harder to park. Consumers or small cars are generally unhappy with this trend, as they wanted a small car for the ease of parking etc, but focus groups are frequently insufficiently well tuned to pick up up on this nuance.

My experience in this industry over many years is that users often don't have a clear idea of what they want, and in the cases when they do a non-trivial amount of time it's a so tightly tethered to one special-snowflake usecase that virtually noone else finds value in it.
If you think any modern hydraulic clutch is hard to push you should try an old z-bar clutch from the 70’s or early 80’s
Very cool to see these ideas coming out of academic work! Any chance you could link any of your papers on the 3D mission planning? Having done 2D autonomous robotics a while back, I'm very curious what new challenges and approaches apply dealing with drones.
The market's notion of "value" is whacked. Feeding a starving poor person is not "valuable." Finding an excuse to decline insurance coverage to someone with cancer is extremely "valuable."

When the market says that one person is 1000x more productive than another, I'd take that with a 1000 kilo grain of salt unless I know the particular market sector to be sane by some other measure.
That is all I was trying to say
>They both give pretty compelling arguments.

Until someone can find a definition of "wet" from a respectable source that states an object cannot be fully submerged in a liquid, the guy sitting down has no argument. He seems to be trying to make the argument that to be wet means a liquid is clinging to you, rather that you occupying the liquid's space. Anyone?
>What you want to compare is how long it takes at a staffed queue vs an unstaffed one once you get to the front of the line (for the same purchase).

Maybe if you're selling a checkout system. Personally I care how fast I can go from "got things" to "left building". (or maybe more accurately: left home -> returned home, but that has a lot more variables)
Probably off topic, but I have to relate this anecdote because its just so funny to me.

I took a new job at the beginning of the year. It was to lead development of v2 of an internal app originally written in Angular and convert/upgrade it to React.

I poked around at it a bit before getting started. It seemed fine, maybe a little slow.

My version got to the point where it could get up to a dev environment. It again seemed a bit slow. I took a look at the build process and realized it did not include gzip (express/compression). I added that in and yeah it seemed about right.

I then took a look at legacy production and... you guessed it, in production for over a year this product had no gzip and was serving a JS payload of 5x what it could be, around 5mb. And no one noticed!

My point is people just don't care or maybe they're just inured to it at this point. There's a lot of "oh for every 100ms of loading time Amazon.com loses $xxMM" talk but in the real world? Not what I'm seeing.
Whenever I read people tirade about divorce my first thought is: well, didn't you know the rules going in? The marriage contract is designed to fit a typical relationship. E.g. a man who makes $45k whose wife makes much less or who doesn't work but does most of the child rearing (labor that, in the open market, is worth a lot more than the $45k the man makes). The rules of property division make quite a lot of sense when applied to cases like that.

Marriage is, first and foremost, a legal relationship concerning the ownership and division of property and the paternity of any children. If your relationship is in the minority of relationships that don't fit into this mold (especially if you don't have kids), why the heck are you married?

Everyone's goals vary, but I got married because I wanted kids and I wanted help raising them from someone with a vested interest in doing so.
I would argue for all those other things simultaneously. We’ve dug a hole so deep it’s going to take some work to get out of it. And most people alive today grew up in this hole, so they’re like a fish who asks, “what is water?”

They only know the hole. The hole seems like a natural, immutable feature of the world.

That doesn’t mean we shouldn’t try. Inaction is a form of action, so it's not good enough to oppose a net good on the grounds that the transition will be painful.
This is about shaming companies, not individuals. Most of the time you don't even know the individual behind the generic customer support channel anyway.

> driver engagement

The same reason I love(d) driving motorcycle. It's a full body engagement. Both hands, both feet, and super alertness and focus on everything around you.
I had a Mazda, but gave it up a few months ago when I moved to the Seattle area... Now I commute by bike (which has manual shifting, but no cruise control :-)) Though my Eastside commute is nothing at all like my old Bay Area commute, not nearly as much traffic.

Here are some other car models with full range adaptive cruise control:

https://en.wikipedia.org/wiki/Autonomous_cruise_control_syst...

And here's what looks like a more complete list of 2018 models supporting it:

Here are some relevant test results which are about 4.5 years old now:

https://modernweb.com/is-jquery-too-big-for-mobile/

At the time, your 3 round trips would have cost about a full second, which is roughly the same as the worst case JITting time for jQuery in those same tests. That worst-case result was on a slow Android 2 device.

Cellular network speeds have gone up, but certainly not as much as mobile processor speeds, so if you re-did those tests today with modern networks and devices, it’s probably a net benefit to pull the jQuery once, then JIT it on each page load, as compared to making even a single extra round-trip per page load.

> Processors aren’t getting any faster.

That’s true on the server side as well.

The article talks about externalized costs, but if you just shift the computing burden to the server, how do you pay for that?

You could load the page with more ads, which eats up the network bandwidth and JIT savings you just bought by moving the processing to the server.

Or, you could charge the users more than you currently do, which is economically little different than shifting the computing burden to the users, implicitly requiring them to buy faster mobile devices and better mobile data plans.

Consider also that the number of bugs created per line of code is roughly constant for each pairing of developer and programming language, so who pays for the costs of the extra bugs you’d expect to find in 2-3x more LOC?

TANSTAAFL.

> JS-heavy pages I've seen tend to have load times measured in seconds.

I doubt you’re comparing apples to apples.

There certainly are many very fat JS-heavy pages on the Internet, but what’s your comparison? If the JS-light alternatives aren’t accomplishing the same ends, then it’s not a fair comparison. You can’t compare, for instance, a web IRC gateway app to Facebook, even though you can use both to transmit plain text to another person.

Not that I’m defending Facebook. I’m just pointing out that they’ve got a wholly different thing going on there than the IRC gateway.

I recently made the mistake of buying a CVT WRX because of traffic and yada yada. Very fun car but the CVT just kills it. I wind up driving the thing with paddle shifters most of the time. And I've almost convinced myself to trade it
up for a manual STI in near future. This whole experience makes me sad sometimes because I know that most fun cars these days only come with paddle shifters these days. This is such a joy kill.
A lot depends on the transmission. In BMW land you can take apart the automatics and often get parts for them. The manuals rated higher for higher power (e.g. the Getrag 420G) you may be able to take it apart (even then you'll want specialized jigs), and you may be able to put it back together (with a monstrous press), but you still won't be able to find new parts for it.

Meanwhile you can take the automatics apart in your garage with few-to-no specialized tools.

The "Business Cycle" section on page 17 is basically a blueprint for money and finance in decade-sized chunks.

1. Early Cycle. Low interest rates and lots of credit increase sales of big-ticket items.

2. Mid-Cycle. Slowing economy, low inflation and interest rates, consumption falls.

3. Late-Cycle. Capacity constraints surface and interest rates rise. "The stock market stages its last advance."

4. Tightening Phase. Central bank raises interest rates in anticipation of rising inflation.

5. Early recession. GDP, inflation, stocks, and hedge assets fall as central bank keeps money tight.

6. Late recession. Central bank lowers rates, stocks rise. Cycle complete.

According to this roadmap, step (4) began about one year ago. In addition to increasing interest rates the Fed has committed to unwinding its QE assets from the 2009 aftermath.

The take-home message is that the Fed causes recessions according to a very predicable pattern. This came as quite a shock when I first read about it in the book "Secrets of the Temple."

Also, there are a lot of gems tucked away into various corners of this essay, including this one:

... a big part of the deleveraging process is people discovering that much of what they
thought was their wealth isn’t really there.
A lot of people consider how much their spouses make completely immaterial, for good reason. Especially since research shows household happiness doesn't really rise over the 100k income mark.

Marriage is designed to be a team. I don't think who makes what should matter, and I don't mind the state treating it that way.

Related story: My father's pension had a choice. 100%x if it stops after you die, 85%x if you want your wife covered if you die early. My dad obviously chose the latter. He had a coworker who chose 100% for himself and died two years after, ending the pension. I can't imagine what he was thinking, except that that he must have hated his wife and just been married out of habit.
> Additionally, arranging your work discussions and decisions around alcohol consumption can absolutely be considered religions discrimination as many people don't consume alcohol for religious reasons and you certainly don't have any business justification for it. Also discrimination on pregnancy status.

What a bizarre claim. Your parent poster explicitly said they tried to organize group activities where everyone - including the old man with bad knees - could participate. Knowing this, it's safe to assume they didn't have pregnant employees (if they chose alcohol related activities while striving to include everyone).

> If not going creates a problem, it's mandatory, period.

Again, such a weird position to take. So, in your opinion, no after work events should ever take place unless every single employee is present at all times and during all discussions? After all, that's what you were referring to with that "problem": a worker who is not present at an after-work discussion, leading to a slightly awkward situation the next monday.
You don't. I've never read it, I have had many jobs.
Yeah I have also found that asking cusomers to rank or sort features using a question similar to this one:

> The bots were routinely pulling off coordinated team behavior that players couldn't figure out, but that worked. This has to qualify as complicated.

This is just not true. Do you know the game? Are you speaking as a player? Or are you telling us what's written in the OpenAI blog post? There is nothing a player couldn't figure out. The caster team lost because of the broken game and because few of them were rusted (Merlini hadn't played for months). The bots were garbage at the TI, and got beaten without any problem by the pro teams.

> Already mentioned that the hero pool has been opened up. Along with the removal of the other restrictions (invincible courier, items) this is basically pure DotA.

The hero pool is still 18 heroes. Dota 2 has over 110 heroes. Can you please try to think what makes you say something so wrong with so much confidence?

> The bots beat a team of 5 casters (granted, with some of the older restrictions in place) who are individually in the top 1% of DotA players by MMR.

Casters don't count as serious players. Would you regard any sports commentators as good players? Would you put 5 of them randomly in a team and say that's representative of the best players of that sport?
A lot of the posted examples include basic copy/paste blocking and password rules. The barrier to better security in these reports is so low as to be non-existent.

That doesn't make any sense to me. Adding a stick shift means you have to pay more attention to shifting and less attention to the road.
This is the kind of misinformation OpenAI is so great at. Otherwise smart people like tlb are led to believe that this was the full game even though it's not even close to the full game. Thanks for helping me make my point.
"In my grandparents' day, it was still possible to construct your own house: you bought a plot of land, hired a concrete mixer to come pour the foundation, bought a lot of 2x4s, and spent a bunch of time hammering & sawing."

> Debian Go packaging team — 64 volunteers. Anyone can contribute; no formal status needed. Don't need to be a Debian project member, even.

As the team have abandoned the usual team set up for Debian, I wonder what effect that has upon the rigour of the packages they produce, and whether this informal arrangement can continue to scale as the call for more volunteers.

Is it successful only because of key players? Will it fall apart when they move on?

Or you can go to the exact same facility naively and pay $10,000 or more for the same scan.

Most likely you don't care, because your insurance is covering it. And your insurance company doesn't care because they'll just raise their rates. And other customers won't care because most they don't actually choose their health insurance; they just get whatever their employer offers.

A free market depends on competition and consumer awareness to keep prices under control. Central planning depends on the government allocating resources efficiently. The US health care system has neither, and the results are exactly what you'd expect.
Let's be honest, LTE was always oversold in terms of its technical limitations. The first reference to it that I can recall seeing (years ago) actually was describing LTE Advanced (~150 Mb/s), but conveniently left out that information.

I know that it had been shown in testing to reach 200 Mb/s - call me when real world usage data can show that kind of result.

In reality, the kind of progress that @barbegal mentions has done more to advance device capabilities, but for something that was initially sold as a 10x speed improvement over 3GPP, it hasn't really panned out.

The telecom folks make a bunch of noise about how you can replace a home connection with these kinds of technologies, but until prices come down and speeds go (way) up, the wireline people don't have much to worry about.
Yes, I understand SSO. It’s just that these structures are already smaller than String/Vec would be by a third, so it’s harder to find something that fits.

> if so, doesn't the implementation simply store a frame pointer inside the lambda,

Yes. That’s what I was talking about. That’s why you’d only be able to store one usize inline. You’d be replacing that single pointer with data. String and Vec have double the available space!

(Incidentally, String can’t do SSO in Rust due to it exposing the underlying storage; there are SSO strings available in a package if it’s significant in your use-case.)
I've been driving stick shift since I first learned to drive (10 years), and I absolutely love it. Yes, driving in traffic can be painful, but the overall benefits outweigh this problem.

I try to describe the situation like this: imagine you have two axis of control with an automatic, the accelerator and the brake. You can use these two independently of each other, and your car's actions will respond to them.

Now with a standard transmission, you're adding a clutch, adding a third dimension, which can also be used independently of the two. The ability and actions your car can take essentially take on a new dimension.

In the case of an automatic, this third dimension is executed by the system, releasing the user from control. However as great autopilot is yet a reality, the world presents more driving obstacles than what a standard automatic vehicle can perfectly account for. Thus giving a "not perfect but good enough" result.

CVTs work too I guess, but I'm also trying to have fun here.

In my personal experience, driving stick makes me more engaged with driving, and therefore more concentrated on driving, while automatics make me feel like everything is easy and I can pay less attention.

I think self/assisted driving would be the key feature to get me off the stick.
I think the problem of stuff going out of date can be avoided by giving background (why it was originally written) rather than making a commitment you can't keep about keeping it up to date.

Knowing why code was originally written can be more important than knowing what it currently does.
Not to defend that interviewer, but sometimes it's inevitable that you do have to code under pressure. I've been in situations where the whole system is collapsing, thousands of dollars are being lost every second, and I have to push a patch to production as quickly possible. Not that I would interview for such a situation.

Sure, but GP is saying that constant planning is the deal. You constantly plan, reassess, and most importantly communicate. And you are always aware of the current conditions of the deal, the opportunity cost, etc. Are you in a bad marriage but hope it'll get better? The opportunity cost is X more years to have to pay alimony if you get divorced. Decide accordingly.
They don't have to. There are limits to how much of a person's income can be spent and some people choose low-paying careers, so their loans never get paid off. Government agencies and schools will pay off loans if you work there; an additional bailout financially-responsible people are missing out on.
Electric or manual?
Stop and go traffic happens in countries where almost everyone drives a manual, so I doubt automatics are to blame.

Why did you want kids?

I always felt like I should want to get married and that I should want kids, but I just... don't. The desire just isn't there. I'm 29 and have been with my partner for long enough that marriage and likely kids are now the next stops on the what you're supposed to do in life train.

And I guess it's not that I actively don't want it. I just don't feel an inclination toward or away from it. There's just kind of an absent feeling about it... There's not anything internal making me want it (there is external pressure from my partner though who does want to get married and from society who expects us to get married).

Does this feeling change? Or am I just weird? Or should I just do it anyway?
What is the "economic contribution" of, say, the average software developer versus the average first grade teacher?
The truly free market is great for many things, but demand for college is very inelastic, and a truly free market requires no barriers to entry - this is not the case at all in either education (certification/regulation) or healthcare (regulation/approval/patents).

If nothing but the free market can work, how do tax-funded government services for healthcare and education work just fine across much of the world? There are 10+ other countries with socialized healthcare and free or subsidized education. The "free market" argument is equivalent to closing your eyes and pretending these counterexamples don't exist at all.
