Counterweights are typically 40% of the a loaded elevator car weight, minimizing the overall work that needs to be done to lift any given car, while also limiting the maximum power required to lift a full car.

What happened to this 'integration' effort, btw?
It would be interesting to ascertain how many times users' on social media flag a security problem to a company's social media team that isn't actually a security problem? In other words, how many false negatives get caught too?

Troy Hunt's post is really told from the victor's perspective (likely a bias rather than intentional or arrogance), but to form a well-rounded view, understanding how many false negatives would likely help...
Here in the Netherlands (at Albert Heijn stores) one small change from the US system makes all the difference: they don't weigh the product after you scan it. No 'unexpected item in bagging area' etc. It goes extremely quickly.

If there's a cashier with more than one person waiting I will go to the self-scanners.
Regenerative elevators do exist. I've no idea what they cost, but, shooting from the hip, I'm guessing they aren't worth the added price on any but the biggest buildings.

Any weight difference due to meatsacks in the elevator will be relatively small compared to what a drum full of concrete weights. Going off the math in TFA, and assuming your average meatsack weighs 75kg, lifting one of them 15 meters up (so, roughly, to the top floor of a 6 story building) stores about half a smartphone battery worth of potential energy. So you probably want to be lifting them much more than 15 meters - and be packing your elevator cars full of them - if you want to pay off the cost of the fancy regenerative kit in any reasonable amount of time.
The parent poster didn't suggest otherwise.

Thanks for making me aware that the author is a prof! But I'm afraid that makes things even worse. As I see it, the writing quality is barely acceptable for an intern: it's so colloquial it almost buries the core message, and it's full of very irrelevant details. Two examples: (1) We're talking about straight vertical lifting from the start, so why bother giving the formula that considers the angle of the force vector? (2) why analyze the energy flow of stacking barrels when the most straightforward implementation (as discussed later) deals with simply lifting barrels some height above ground level?

This article could have been more clear and more approachable after editing it down to half the text.

AIFMD / MIFID come to mine although the regulatory burden seems quite low with those two (comparing to insurance Solvency II).

I would venture that the willingness for 2 and 20 has dropped to more like 1 and 10 or less. That would explain the double minimum size as well.
> as the concrete used for weight here would be less than the amount used for a dam

Think that through.

A dam probably holds 100 or 1000 tons of water for every ton of dam material.

A concrete weight holds exactly on ton of concrete for one ton of concrete weight material.

And "amount of weight helt", be it water or concrete, is Exactly what matters here.
Regulations where it's clean.

But 'net neutrality' for example plays right into the hands of the FANGs. Networks can't make you 'pay per email' thereby allowing more of the surpluses to go to the FANGS.

If there is 'network neutrality' - one might wonder if we also need 'search neutrality' i.e. if you're in the search business, you can't look at that data to infer anything about that person to sell them other kinds of services.

The Office Suite monopoly seemed overwhelming just 15 years ago, but cloud services just got so much better it seems a lot less relevant these days. I haven't used 'MS Word' in forever.

It's probably start time to think about maybe some regulations (specifically with regard to neutrality) in search, but beyond that I don't think there's quite a need to intervene yet.

You can trust your software only as much as you can trust your hardware. If the hardware (or opaque firmware that you can't control) is specifically furnished with a government-imposed backdoor, secretly from everyone, then software encryption may give you little.

Transparency / openness of hardware gives you more chance, but it's hard to obtain.

The only problem is that we don't have nearly enough space for that.

An acre of trees stores ~393 tonnes of carbon dioxide permanently (in Vermont anyway, other areas probably vary a lot) [1]

Humans generate ~40 Gtonnes of CO2 a year. That means we need to be adding ~100 million acres of trees every year to capture that. There's currently 4 billion hectares of forest cover - that's around 10 billion acres.

If we replanted every area which has seen deforestation since 1990 we'd get another 400 million acres, or 4 years of emissions. After that, we're fighting an uphill battle. Forests currently cover 31% of the earth. 29% of that surface is desert, 3% is urban areas and 10% is covered in ice. To keep on top of emissions we'd need to add 0.3% of the total each year globally, or 1.2% of the land which could actually grow trees.

That might be doable in 5 years, but 10 years? 15 years? 30 years?

Re-forestation may be part of the solution, but it can't be the only part.

Yes, but... once some degree of peace and independence is achieved, social improvement happens at an astonishing rate. Take Iran. At the time of the Revolution in 1979, it was one of the poorest countries in the world. The birth rate was above 6 (I find birth rate is a very good proxy for economic/social progress). It dropped from above 6 to under 3 in just ten years - a feat that took England 95 years to accomplish. Today, Iran's birthrate is less than Europe. This is a result of (relative) peace and independence.

China is a particularly wild example. Per capita income there has grown about 15,000% since 1952. That's crazy, but it happened.

"All that we have to do is to send two Mujahedin to the farthest point East to raise a piece of cloth on which is written al-Qa'ida in order to make the generals race there to cause America to suffer human economic and political losses without their achieving for it anything of note other than some benefits to their private companies. This is in addition to our having experience in using guerrilla warfare and the war of attrition to fight tyrannical superpowers as we alongside the Mujahedin bled Russia for 10 years until it went bankrupt and was forced to withdraw in defeat. All Praise is due to Allah.

So we are continuing this policy in bleeding America to the point of bankruptcy."[0]

Great advice. As someone who is on the self-taught path, and employed as of recently, I would recommend the following as well

- Start digging into data structures and algorithms early and often. Leetcode is meme status now, but it does help to practice routinely. Don't wait until 2 days before an interview to try to learn how to these things. Grokking Algorithims, the Algorithm Design Manual, and Cracking the Coding Interview all helped me out along with constant practice

- assuming you'll be front end focus to break in, get a good understand of how the internet works (and be able to describe it well). It's a go-to interview question for front end positions

- Dig deep into Javascript. Understand why it's useful, and more importantly, what the issues are with it so you can avoid those pitfalls when working with it.

- Learn React. Vue/angular/etc are all helpful and good to know, but React is getting more widespread by the day. It's pretty easy to pick up once you have a good JS foundation, and there's tons of learning materials.

- Learn about webpack and what it does. You don't need to know how to configure it from scratch or memorize its docs, but know when and why its used and how it helps your project.

- Most importantly, learn how to get stuck. Try things that are really hard, get stuck until you want to give up, then try some more. Get comfortable not knowing how to do something, but figuring it out.

- Don't get too bogged down learning the right tech stack. Pick one and go hard on it for most of your time learning. No matter where you end up, the stack will be different. Starting over is common and most places expect you to have 'ramp up' time to get used to their dev environment/stack
and remember that corporations are by definition a collection of individuals... is public shaming really the only way to get through to the decision makers? I hate the thought of regulations... but maybe there is a $$ solution here?

Browsers should ignore this crazy decision and keep (or add) SQLite in the browser - is still in Chrome but deprecated.

A global financial system should absolutely not be able to be taken down by fraudulent behavior like writing shitty loans. You can point all the fingers you want at them, but ultimately that's like saying that the intern who was able to push changes directly to production is the reason your site now shows nothing but cat pictures: they had a hand in it, but the fact that it happened points to much larger and more pernicious structural problems that, while everyone else might have been doing their job correctly, indicate that the system obviously didn't do the thing you need it to do.

For comparison, I believe the amount of and methods with which Google collects data to be wrong, but I also believe that they don't believe they are doing something (outright) wrong.

Most major chains already have apps, at least I Know McDonalds and Burger King both do. The McD's app does have online ordering too, and you can pick it up at the restaurant. Less chance of confusion when dealing with a screen or mobile device if you don't have a standardish order.
Yes, the crooks probably "legitimately" owned this name (given that their line of work is stealing credit card details it seems plausible they'd have used stolen cards to buy the domain, but maybe not)

It probably wouldn't have tripped as "phishing" unless the crooks were dumb enough to host false BA branding on it, rather than just an API to accept the stolen credentials.

Because "BA" is so short and non-specific I'm doubtful that tools like Facebook's Certificate Transparency based "phishing warning" would have been useful here. And if you were an over-worked BA employee given 500 CT "phishing" warnings a day, what would you do? Visit the site in Chrome maybe? Then you see it has a generic holding page, no sign of phishing, you file it as a false positive, move on? How are you supposed to know it's being used by crooks?
So the question is why don't companies have infosec individuals seriously looking into issues raised by a user seriously because its in their best interest to avoid bad PR and public shaming which will be the logical next step if they ignore it.

Is the shaming necessary? Do corporations only respond to an issue when it blows up? Seems like bad stewardship.
What's infuriating is the claim from those companies to be secure when they aren't.

If, as you suggest, they should be given a pass on data safety, then they should be barred from making promotional statements about data safety. They violate the social contract by making false or misleading claims.

(Emphasis mine.)

Well. The moment you have evil code running on your box, as you, then I'll naively assume you have a bigger problem to deal with anyway.

> The clipboard is a big public billboard visible to anything running on your computer.

And everything from client work to love letters in my home folder is available to anything that runs as me, unless I've gone out of our way to secure it - and succeed.

Not saying the clipboard isn't a problem.

Not saying browsers shouldn't expose a carefully thought out API.

But the way I read your post it might scare people away from password managers and back to a single password or passwords written on papers stored within reach from the workplace.
Maybe keylogging in the strictly literal sense, but I think most software "keyloggers" log the clipboard too. I suppose it would protect you from a physical keylogger.

I used to be very into supplements. I've looked at many published papers, and my conclusion is that there is a huge issue with the quality of publications in the health/medical field. Many of the studies around supplements are funded by people selling the supplement, and, big surprise, they go the way the people funding it wanted them to go. You will also find many independent studies contradicting these findings. You're left wondering who's right, who funded those studies, whether you can actually trust their methods.

What's worse with Cannabis is that there is a big ideological battle going on. It's gotten political. There are people who seem to believe that Cannabis is some wonder plant that cures cancer (I'm serious). There are lots of people claiming it helps with anxiety. Me, I'm 100% pro-legalization, but whenever I've tried smoking weed (of any strain), it's made me extremely anxious and paranoid. I've even had a panic attack after smoking a joint (and I never get panic attacks!). It seems obvious to me that Cannabis doesn't have the same effect on everybody, and that it's not universally good. Just like everything else in this world, things are more nuanced. I just wish people could see past their own ideology and stop trying to push the idea that this drug is either universally good or universally bad.

TL;DR: scientists aren't always impartial. They can be bought, or motivated by political ideology. Both of these things get in the way of real science.

Languages, macros, libraries, and apps are in descending order of how many people will use them and how tightly coupled they are to their problem domain.

Sounds like it was mandatory.

>And that person was excluded from work-related conversations that happened at after-work bar trips, which caused some awkwardness when the rest of the team aligned behind a significant decision and the excluded team member felt like he wasn't consulted.

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

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.

I'm sorry but "some employees desire youth-oriented forced 'socialization' after work hours" is not a justification for breaking the law, it just isn't.

If you are or know a very tall man, 6 6 or something, you might see this occur.

When the man walks into a room and finds there is someone of his height, or someone even taller present, the man begins to feel a sense of insecurity about this challenger. Suddenly he isn't the tallest guy in the room. It feels like a threat, it feels like competition.

I know this is a general feeling for certain. These men don't walk around thinking they are better than everyone else because they are taller but when they finally encounter someone of their height they are really sensitive to their presence.

I can't imagine women feel the same way. I've actually heard that women have insecurity about being too tall. If ones security about they masculinity and femininity can be shaken by their height, but in totally different ways, there might be something real about it. I do know that a lot of guys are excluded from the saying pool because of their height, and I know a lot of women value height in attraction.

The correlation of testosterone, power, and height in men are all in alignment. It's part of a male concept.

The infamous David Reimer case is a great example of how boys and girls are just different. David adopted all of the male stereotypes even though he was being raised as a girl with hormone therapy, psychological reinforcements (to try to teach and convince him he was a girl) from toddler through primary School. He still wouldn't conform and his brother knew something was wrong. When they found out it was an experiment the brother killed himself and David began to identify as a man again, he even went on to marry a woman. He killed himself in his 40s I believe.

The idea of a convenient truth and inconvenient truth need to be considered. I see it so much today that people are willing to twist facts and blow up supporting minutia to convince themselves that men and women have equal capabilities and have equal values as human beings (atleast evolutionarily).
For some perspective on this sum, the (edit: annual) GDP of the US went from around 11 trillion to around 18 trillion during this same time period.
Thing is if I'm eating at a fast-food restaurant, I'm not that bothered by food quality. In-n-Out doesn't have anywhere close to the same burger quality I could get at other joints, but it's cheap and relatively good for the cost.
