Maybe what they're referring to is the idea that doing a wide variety of different motions can be really useful. This is why cross-training is important for athletes who want to be their best and healthiest.

For example, if you're into running, this strengthens your legs, but it focuses on certain specific muscles and neglects others. So you want to do some other things like biking or ideally something with lateral movement like playing soccer or tennis.

And it's not just strength and endurance to consider.

The body also needs to learn to do certain motions correctly, because part of fitness is the habits your body has to activate certain muscles in certain sequences. When you walk or run, it's important how your foot lands, and it's important how your knees bend (so your muscles can absorb shock, not your joints), etc. Movement is a skill to be learned that requires practice until doing it properly becomes second nature, a lot like playing a musical instrument.

And of course there's also flexibility.

Anyway, maybe their point is that merely doing strength training is better than nothing, but it's not a substitute for including squatting into your daily life so that you do 100 different variations of squats and squat-like movements. For example, if you unloading the dishwasher by squatting down, extending your arm and leaning over to grab some forks, and then twisting around and standing up partially to put them in drawer to your other side, you're going to trigger different muscles than if you do squats in the gym.

I agree with you in condemning the indiscriminate killing done by the US. Technology may make existing operations slightly less evil.

If you look at the developments to the hellfire missile: https://www.thedrive.com/the-war-zone/31409/everything-we-kn... . You can see that it's now more accurate and less likely to cause collateral damage.

The problem with the technology is that the more automated it gets, the more tempting and easy it is to use this technology liberally and frequently. I'm not against the inherent development of the technology. Only its application.

I'd be surprised if many of these "employees" weren't actually contractors or part-time roles as is typical of institutions which lean heavily on college-attending employees who need to work around their class schedule or are purely entry level on their way to a more traditional career.

Boarding methods in use approach the absolute worst approaches to getting everyone in a seat with a continuous stream of passengers boarding - having literally no organization would actually result in faster boarding than the zone based approaches.

As a result plane boarding gets a lot press I think, partially, just out of the hope that airlines stop acting so idiotically.
You’ve fallen into the fallacy of equating availability of advertisement to availability of knowledge. Knowledge is supposed to be a direct result of some observation of reality, advertising is usually a created and modified reality designed by someone (who is using their knowledge of the psychology behind it funnily enough) which displays the product or service as a requirement for improvement of the person being advertised too’s life. The goal of advertising is to sell, the result of knowledge is to understand. Two very different things.

They do that all the time and it's not for passenger convenience: it's to shave minutes off the turnaround time and get more flights per day. They also almost never use an airbridge even in airports where that is standard. That's both for speed (Ryanair's guys on the ground can get the ramp there faster than the airport employees who drive the airbridge) and for cost savings, since airports charge for that service.
JavaScript has types. typeof {} === 'object'... Sure, they're very weakly held, which can be a lot of fun when you accidentally add a string and a number, but variables have types.
That is true, but knee position relative to toes is more of a diagnostic for other form issues rather than something to try to optimize for in it's own right if that makes sense. If you are breaking at the hips (ie pushing your butt backwards to initiate the movement as opposed to sitting straight down on your ankles) and also breaking at the knees (ie pushing your knees apart to start the movement) properly, then your knees will usually not go passed your toes. If you find that your knees are going far passed your toes, you probably aren't doing at least one of those things correctly. It also usually means that the bar is not over your heels so you are moving it inefficiently.

It's similar to when people say "chest up" for squatting which actually has nothing to do with your chest directly and is instead a diagnostic for if a person's back and core are tight. If your back and core are tight then your back won't round and therefore your chest will appear "up".
Crazy. That would be like an average American household getting fined $150 (63000/40/52)... so a speeding ticket basically.

I wish airlines and airports would work at getting the checked bags off the damn plane faster. Whenever I check a bag I could have carried on, it feels like I'm being punished for it, as inevitably it comes out 1 minute after the every-30-minutes train departs.
OP didn't mention Safari or Brave either, don't be so hair-trigger looking for offense.
And those boarding last roll their bags down a full plane banging into seated people along with jostling them around by using the headrests as railings.

And it’s all the airline’s fault imo.

Offline-first is already a planned feature and only missing because of the lack of development capacity.
I think there is also pressure from connecting flights, if the plane is running late it's not uncommon to see people with really close windows jump the line in terms of deplaning - sometimes with the assistance of the flight crew.
I think it’s possible that some minor actor is doing it (which I suppose would mean it’s almost certain that someone does it), but it’s likely not done at scale or at a big actor such as Facebook, Samsung or Google.

Most people who are creeped out about things like “I talked to my friend about traveling to Aruba yesterday and today on Facebook I have ads for trips to Aruba!”

First of all you could have had those ads all year but only noticed after the discussion. That’s the simplest explanation.

But also, if this was indeed a friend (or someone who was ever e.g. the recipient of the same email as you, or has friends in common with you etc) then that person perhaps shared that they were in Aruba recently. Since the two of you were in the same location when you talked, a clever advertiser could show you ads for products or services that people they think you interacted with have already bought - such as a hotel stay in Aruba.

I’d really like to hear if anyone has first hand experience with spying like this - and the fact that no one has yet come forward and confirmed it suggests it must be rare.

I have an NVME SSD as a boot drive in my desktop and three years and change in (say 1200 days) it’s used 40tb of write (out of an advertised 400tb endurance so I’m not too worried). That works out to about 30gb of writes per day, which seems about right for medium to heavy use.

I guess what I’m saying is that for modern SSDs I don’t think write endurance is a binding constraint in most cases.
I've been there. I had a job where after 3 months... There was a crapton of technical debt, we had a new PM that was useless, no one seemed to know anything, every user story was written for everyone except me, yada yada. I wanted to bash my head in daily. Then one day it got better. The hung on long enough to find a few people who had been around long enough to know a bit about what they were talking about, and then I started learning how they stay sane. A lot of it involved mastering how to tell people they needed to up their game in communication before I was gonna do work they asked me to do.

No magic answer, but in general I find I'd rather work on a fucked up environment where I can make incremental improvement than a good-enough-for-people-who-aren't me environment where everyone is to comfortable to tolerate any changes.

Yes, it is probably true. There are less complicated subsets, but using PNG to save the picture of the page might help better (although PNG doesn't used with CMYK or with extra separations). There is also DVI, which TeX uses as output, and it is simple so a program can easily be written to rasterize it or to convert to whatever other format the printer uses.
They are only mutually exclusive if your business and product management teams deprioritize security. In my experience, the typical reason that security gets neglected (as opposed to just making reasonable trade-offs) is that management and product management both care too much about just shipping shiny things and don't care enough about doing right by the end user. I've seen better and worse teams. Most teams fall into a category of "you're lucky you're not big enough to be a target."

General best practices I can think of, in broad organization level strokes:

1. Make sure security is implemented at the dev ops layer through practices such as logged just-in-time access to production systems, secret vaults for service keys and certificates, airgapped machines for handling secret keys, etc.

2. Make sure security best practices are implemented by default into your API's (CORS, TLS 1.3, whitelist based firewalls between services that shouldn't need to talk to each other, etc.) and make it transparent to the API caller, at least when it's your own services talking to your own services.

3. Make security an element of design and code reviews. Square, for example, did this by having subject matter experts advise teams on security design when projects were still in the ideation/design phase.

Ultimately, security costs a non-trivial amount of time, and it requires training your developers to be able to reason about security.

One of the implications of "quitting contracting" for me is that I'm not letting myself compare anything to my contractor day rate. Suffice to say for the last six months, compared to contracting, my income has been basically 0.
It really isn't that though, governments never have enough money to provide for all the things that their residents are asking for. It isn't really like "oh, let's grab some more taxes now just in case we need it later", its more like "how do we upgrade from a B-level city to an A-level one?" or worse: "how do we fight off a downgrade from a B-level city to a C-level one?"

The American tax burden isn't really that bad compared to everywhere else in the developed world, especially for the facilities that we demand (huge houses, less density, lots of roads, nice schools with football stadiums, etc...).
Why is it better to board first? From my perspective, minimizing time spent in cramped air planes seats the better.
What you're saying is true, but it's just the price floor and often not the actual sale price. It's more often "what the market will bear." "Professional" customers are often happy paying significant premiums. If it makes me 2x-10x more productive, the cost is of little relevance. "Consumers" are a lot more price sensitive. A durable orbital sander doesn't mean much if I only use it once every few years.

I do hate the idea of software unlocks, though.
The conclusions are pretty obvious, I guess they just needed to simulate it?

The fastest boarding I've ever experienced was something Cathay Pacific did a few years ago. In the boarding area they had three lines with a bunch of section signs and an a couple employees hassling/sorting people between the lines. The rear of the plane sections were at the front of the line. I'm guessing they were just counting how many people were in each section?

Either way, when they opened the doors, they just picked one of the lines and the employees walked down the line scanning everyone's boarding pass and then the whole line proceeded to board the 777 (dual isle). Then they repeated the process with the next line after a short pause.

Which works out to back to front boarding of 1/6th of the passengers in a section at a time. When it was my turn the entire line pretty much just walked onto the plane bumped around a bit in the section and sat down.

Quite a shock given the hour long boarding AA can sometimes pull off with their messed up boarding order based on miles and cabin front to back...

It still sounds like you're looking at tiny (≤4Gb) flash chips (or NOR?) for embedded devices, not 256Gb+ 3D NAND as used in SSDs, memory cards and USB flash drives. Micron 32L 3D NAND (released 2016) had 16MB blocks for 2-bit MLC, ~27MB blocks for 3-bit TLC. SK Hynix current 96L TLC has 18MB blocks, and even their last two generations of planar NAND had 4MB and 6MB blocks.

Having only 2 or 4 planes per die with per-die capacities of 32GB or more is a big part of why current SSDs need to be at least 512GB or 1TB in order to make full use of the performance offered by their controllers. 265GB SSDs are now all significantly slower than larger models from the same product line.
Overhead bin space is the big reason- give the somewhat (last 5 years-ish) changes to charging for the 1st checked bag, many who would have otherwise checked a bag are bringing on as carry-ons.

Many flights I've been on in past several years have had a real shortage of bin space, meaning getting on board early to make sure you're not the odd man out IS important (waiting for baggage carousel can take an extra 45 minutes)
Fun side effect - if this method was adopted people might slow themselves down in boarding to board earlier resulting in even less efficiency.
My anecdata of one: As an employer/founder, I wouldn't hold a short stint on your job history against you. I'd give it an equal chance of being a poor employer vs. you not working out. Would likely just ask you about it in an interview. If it were a few short stints in a row, then that might give me pause. But in my experience, this situation is more common than you'd think and any good employer/recruiter is going to be able to look past it.

Would you want to go back to your previous job? It's possible they might want you back if you left on good terms. Would be easier, cheaper, and faster for them than backfilling your position.

Great video. This is one of those phenomena, like how to fix traffic jams, that everyone has an opinion on because of firsthand experience, but few people know about the actual research on. Despite there being known fast methods, I think 2 things stand in the way of implementing them:

1) Business and 1st class make a lot of money for airlines. Not letting them board first (although personally I've always wondered why this is desirable) would devalue their tickets and make less profit for the airline.

2) Airplanes have to undergo certain maintenance checks or procedures whenever they land. Those take some fixed amount of time. There is no incentive to speed up the boarding/deplaning process past that fixed amount of time, since it won't be the limiting factor.
> hardly anyone is going to charge the gate to board out of order

I don’t know if it’s anticipatory anxiety or what, but I seemingly observe half the passengers stand and get in line at first call. And even queue up for the queued boarding calls.

I always get on toward the end and never had an issue finding space, but I understand it’s aircraft and airline dependent.
It's not at a monetary point. It's usually when the company has succeeded to the point that it's not in danger of failing, even if inefficiency sets in. Once it reaches that point, then it's a matter of how long it takes the culture to rot. (Most cultures rot eventually.)

I wonder if "immoral maze" explains our politics as well, and if it has the same cause. The US hasn't been in danger of failing, even if the government became insanely inefficient.

> and means I don't have to sysadmin my telephone.

This is exactly why I've stuck with Apple for my phone. I don't upgrade every year and all that nonsense, but I prefer their ecosystem for just that reason.

I don't want to use my phone that much that I would want to load all kinds of different software onto it, especially if it compromises the privacy and security in any way.

I even consider the limited software a feature in that way.

The simplicity is what I like about it.
Number of levels in the hierarchy seems like a bad way to determine this. I've worked in a company with 500 employees (and three levels) and lots of bureaucracy and a company with 100,000+ employees (~6-8 levels depending on your division) with relatively little bureaucracy (yes, on occasion, I ran in to bad cases of it, but it didn't effect my day-to-day work).

It's simply not possible to have 100,000+ employees and less than 6 levels, unless you have managers with tons of employees. But it is possible to be in a division of a large company where your group has relative autonomy and are empowered to do what they need to do. In my case, there were about 20 of us inside of a larger 500 person group. 95% of decisions were made within the 20 person group (obviously this is an approximation). Another 4% were made at the 500 person group management level. 1% were made by company-wide executives. In other words, my boss was accountable for most of what we did. On occasion, he's need to go to his boss for something. And very rarely, his boss would need to escalate to higher ups (where there were another 3 or 4 levels to the CEO). This company was very well run, but there are much smaller companies with fewer levels in the hierarchy and lots more bureaucracy.

I totally agree that the value of such an apprenticeship depends on how titanic the master is, which means it's mostly not going to be all that valuable.

I still think Naval understood the point about negative value perfectly well.
I wish that was formalized as well. If you have a 5 hour layover, or need to wait for checked bags anyway, and rush to deplane, you’re just creating real problems for others with minimal benefit to yourself.

I speak Japanese, have spent a lot of time in the country, and have a great admiration for its people, but about the last thing I’d express any admiration for are its politics and media. And speaking anecdotally, very few people there seem to put much trust in them either.
I ran into a situation about the same as you. I just explain things to places I was interviewing with that the situation didn't match the interview process and despite my best efforts, I just have to move one. Now, I was lucky that I had been laid off and this was the ``rebound job'', so I didn't have a history of changing jobs. Only one potential employer had an issue with them, but I did find a very good job and moved on.
> Does advertising cause people to spend more than they would otherwise, or not?

Yes, it does, though not as much as they wish they could spend. Hence the unhappiness. However, it also distorts the allocation of that spending.

> If it does, then eliminating advertising would reduce spending which is what causes a recession.

People would not stop buying stuff without advertising. They would be more likely to spend the money more on vacations/experiences. Trusted reviews would become a much larger industry. This is different from ads however, as it would be paid for by the consumer. I suppose companies could also pay the reviewer to include their product when doing a round-up of the various options, assuming that all of the competitors paid the same amount, there's no reason for the reviewer to be biased.

> Looking around the world, it seems to me that many recessions didn't, in fact, end. Instead, their economies imploded entirely.

How many of them were caused by banning/regulating direct-to-consumer advertising?
