Another thing they don't mention is that when utility AC returns, each UPS in the chain tries to recharge, which can be a significant chunk of power. Any given UPS is sized so that its downstream load plus its own recharging power doesn't overdraw the circuit, but add two recharging powers and it's much more likely.

I don't think this is an issue with double-conversion UPSs, since their input power is fixed by their rectifier size and they'll simply charge more slowly instead, but with standby type, it's very much a concern.
I would not like to be in that capsule, that's for sure.
The UK established world dominance due to colonial trade during its Empire era, the industrial revolution, and the rise of financial institutions (in the early 19th century).

The UK's international heyday came at the end of the 19th century and beginning of the 20th century. Arguably, the power and influence of the UK has declined significantly since WW2.

Immigration to the UK prior to WW2 was pretty minor (e.g. the Huguenots and Irish immigrants). The last census prior to WW2 was in 1931 and showed England and Wales had only a 2.1% foreign-born population. By comparison, immigrants made up 6.6% of France's population.

Widespread immigration only occurred in the post-WW2 period, due to serious labour shortages in the UK. It was then that large numbers of immigrants, mostly from former colonies, settled in London. And then there were significant waves of immigration from Eastern Europe in the late 20th century due to globalisation and the enlargement of the European Union.

With that in mind, we need to be careful we're not confusing correlation and causation.

My interpretation of the timeline is that the UK became an immigration magnet due to its prosperity, rather than its prosperity being the result of mass immigration.
Active for a period is still continuous during that period.

As opposed to “active when called”. A function, being called repeatedly over a length of time is reasonably “continuous” imo

It's funny, I recently switched from a backpack to a hard carry on case specifically because using a backpack was causing me to have to store my bag under the seat in front of me, thereby losing space for my feet and having to deal with my legs being squashed and my foot at an uncomfortable angle for the entire flight.

Show HN: Beautiful 3D ISS tracker with live video and near-realtime clouds
This is a little hobby project that I hope you enjoy. You can see where the International Space Station is now, with live HD video from NASA, on a realistic 3D globe. The positions of the sun and moon are also accurate, though distances aren't to scale.

The clouds are also near-realtime; I span that out into a separate project at https://clouds.matteason.co.uk, where the cloud images I create from EUMETSAT data are freely available.

I've got more features almost ready to go, like the ability to turn off all UI, toggleable clouds and turning off the day/night cycle

I'd love for it to be used in education, so please do share it with any teachers you know who would find it useful
(2021) - this is a great book and I thoroughly enjoyed it.
I came across this reference in a book this morning and the April 22 date caught my eye. This article by wired.com was published in 2010. 2010 (already 14 years ago) feels like a big turning point in web technologies as well.In 31 years, look where we are. I was 10 in 93' and discovered a new world through Mosaic, and then Netscape. I was lucky enough to have a family computer, a modem, dial up, and had spent hours and hours on BBS's prior. The rest is history. The web made me. The web made us. Tim Berners Lee, thank you.
Thanks. There are some really interesting points in your message. I'll be talking and writing about our values and mission in the coming weeks and observing the feedback - actually, we already have some but not sure how to stand out among the noise.
Java has been proven to work fine. I wouldn't use it for programming an OS, but it's absolutely massive for web development and other backend stuff.

Applying patches to the Linux kernel isn't that hard? Porting abandoned code sucks, but putting in the work to finish and include the patches would just move that annoying work to the rest of the kernel instead of a few people working on weird SoCs.

> essentially you are saying rust is great because companies can hire clueless people and rust will compensate for their inability

That's not what I'm saying, at all. What I'm saying is that nobody is perfect, not even C developers. Even if the mythical perfect C developer, who writes bugless code, does all the necessary sanitization, and always applies the necessary layers of tooling even when personally inconvenient, does exist, they can make better use of their time by using a language toolset that doesn't necessitate that extra work in the first place, regardless of whether that's Rust, C++, Zig, Frama-C, Carbon or Jakt.

The "everybody who makes mistakes is clueless" crowd is exactly why C developers get such a bad rep. C compilers have a billion warnings and -Weverything -Wnoimeaneverything -Wnoeverysinglething exactly because C developers, like any other developers, need help.

I thought one of the main advantages of QC was that it could (theoretically) solve existing problems that have exponential time complexity with more efficiency. Isn’t the idea that it could make everything faster? Or did I fall for the marketing.

You are not. Its same security any other stack would do.

This “PHP security is terrible” is mostly because people remember stories from 20 year ago (when none of the cool stacks didnt even exist) and things like Worpdress the most targeted cms/framework in the world.

I have suspicion that if Vercel/next powered 60% of web than its security reputation wouldnt be great either.

PHP is flawed but so are all the other stacks. PHP is old but that doesnt mean its not being updated or up to date. If anything its boring.

Look, when you publicize information that is not a human creation or art, you are GIVING IT TO THE PUBLIC.

The berne convention intentionally left out database sui generis rights outside the scope of copyright. Only in the European Union you have the kind of protection you're looking for. And even in the EU, I've never came across a case where the law was enforced in courts. Maybe because it's a ridiculous right, in my opinion, that would make information flow disfuncional in society.
Executive level education is a tricky tightrope to walk in my opinion - often you’ll hear upon completion “I now know enough to be dangerous!”. Practically, and I mean this in the most endearing way, it translates to “I know enough to be confidently incorrect”.

AI is a wide field. The hot topic is generative AI.

If you really want to learn the depths, I’d start with brushing up on statistics 101 and 201. At least you’ll know how to run controlled experiments to see if these AI work.

For practical, hands-on learning it’s hard to go past either Jeremy Howard’s FastAi courses or Andrew Ng’s deep learning courses. The latter is via Coursera from memory, so you can put a little sticker on your LinkedIn if that’s a factor.

For executive education, I’d point back to my opening quote. Either do the hands-on learning that is rapid or sign up to a 2-year exec Masters program. MIT offer a fantastic, full-course load Exec MBA (that you get a regular MBA diploma at the end, it’s not watered down in accreditation or effort). In doing so, you can specialize heavily in AI/ML and you will be coding in those classes.

"We can't be certain what it is, therefore, we are certain it is aliens."

You're right, and it's funny thinking about it in more abstract terms. Being "unidentified" means we can't match it to any known phenomenon, to then jump to being certain it is aliens is silly.

Iron Dome is a symbol of failed foreign and defence policies. 7th of October showed that defence and appeasement does not work with genocidal jihadists. The source of attacks needs to be destroyed and building forever growing protection systems is not a solution.

I've been using contactless for the majority of UK train and tube travel for many years now. Phone is most convenient, but adds a significant stress factor!
Using Python for a serious backend thing at a telecom firm is a big no-no, and I say that as a guy who has been paid to write Python code for almost 20 years now.
Notice how you fell into the race trap again, even though I said "of any race". It's not "the ultra rich minorities", it's "the ultra rich, period". Race doesn't have anything to do with what is 100% a class problem.

The existence of meatspace never stopped the early web from flourishing, so why should the existence of the modern web stop anybody from making a second web? The only reason that Google was useful is because it tapped into the trust network that already existed before it.

I feel like the social media churn has destroyed people's brains, because they're more interested in stopping people from doing things they don't like than doing something awesome themselves.
> Yeah this info, very condensed, should just be on big signs at station. ”You can just tap your credit card and travel, no need to do anything else at all”.

This messaging is all over TfL stations and advertising. If you're stood at a London train or Underground stop for any length of time, you're likely to hear the overhead tannoy repeating a message about how convenient contactless cards are, and how they charge the same (cheapest) fare as the official Oyster system.

It's a testament to how hard telling people anything is, that having a popup on the ticket machine is still effective.
> The plane leaves at the same time for everyone anyway.

And I'd rather wait for it on the plane than at the gate. Once I'm on the plane that's it for X hours, can relax more, nothing I need to do for a while.

You realise they sell (or it's a perk of travel class / reward system / etc.) priority boarding right? Some people do value boarding early, they're not confused and think the plane is going to move sooner.
No worries! Yes, exactly. It's also similar to doing arithmetic with and without units. Sure, you can do arithmetic without units, but when you are actually working with real-world quantities, but you easily get yourself into a muddle. Unit-carrying quantities and algebraic systems built on them prevent you from doing silly things, and in fact guide you to getting what you want.
Also, is this a “one drop” rule — where a single foreign founder and three domestic founders counts as a “foreign founder”?
You can buy an Oyster RFID card at the machine for any travellers that don't have bank cards. The fare is the same.
A lot of people won't get your sarcasm, but I agree with this. Not that simple, life isn't fair, some people are more attractive/charismatic/interesting than others. Also, if you are geeky or considered weird by others, you can only find comfort with other people like you.

And the blanket suggestion that gym somehow solves everything is stupid.

> if users click a lot, is it because they find many valuable things, or because they didn't find what they were looking for?

Why do you care as a search engine? This is a natural human problem that can't be solved with technology, only by humans.

It used to be, that I went to page 5 of Google instantly, because that was where the real results were. The first few pages were people who knew more SEO than sense.

These days, that doesn't work since "semantic search" because now it appears to be sorted by some relevance metric and by about page 5 you start getting into "marginally related to some definition of what you typed in but still knows too much SEO to be useful."

The point is, this was already a solved problem if you knew to go to about page 4-5. Then people started trying to use a technical solution to a very human problem.

Hello, a very interesting project. Conratulations for putting everything together.
I have expressed some thoughts in the discussion sections of Cognita github repo:
https://github.com/truefoundry/cognita/discussions/146
It would be great if the maintainers could reply.
Yes, that was the joke. :/
It isn't that paradoxical. Waiting until the last minute can make a you victim of the "overhead bin space" pirates who load up the bins with stuff that should have been checked and leave you to worry about gate checking.
Why is overall ridership down?
Another important point is that an UPS can produce huge surge currents, for example when switching from battery to utility. The upstream load goes from zero to the sum of both the protected load and the UPS charging its battery.

When daisy-chaining an UPS to another, the downstream UPS can easily overload and trip the upstream UPS because of that.

That was my own initial reaction. After viewing a bit of the video, I'd changed my mind, and by the time I'd viewed the whole thing, had nominated it for the 2nd chance pool (where it's now sitting).

It seems to me, that the main focus of the article, was talking about how a very simple UI change (a pop-up cancel option) made all the difference.

On the other hand, these types of popups can be incredibly disruptive to the UX, especially if the text is badly written, and there's no clear utility to the user. All too frequently, these types of guardrail popups are there, only to advance the agenda of the developer/service provider, and not the end-user.

It looks like the popup was well-designed, the text was well thought-out, and the user advantage is clear.
I'm quite taken aback to be viewing a Google website where the 5.8MB images are loading at a crawl, because they're completely unoptimised pngs equal in size to bmps of the same resolution!

Oh hey apparently there are some 26MB of mp4s that didn't load at first, they served a 2.4MB "Mobile" mp4 instead, so it's not all bad.
Although this characterization does not represent a lot of the analyses, and I think it's silly to "homogenize" a group of people and misrepresent them via stereotype.

Isn't that a definition of discrimination? That seems to be

It is easier to cheat the system with paper tickets, which I think is part of the reason the costs are set so high.
What a stupid article. It doesn't tell you anything beyond "no, buy our products instead". WHY is it bad? HOW does it fail?

I mean, it's possible that I don't know enough about UPSes to understand the finer details and all this would be obvious to someone who does. But presumably they already know why it's a bad idea, and don't need this particular article to explain them.

The amount of scare words and the lack of detail honestly make me believe it probably IS okay to do, and Eaton just wants to scam some extra money out of people. It's just the posts in this thread that make me take it slightly more seriously.
You are onto something here. I myself have overcome this horrible state and the no alcohol thing is pretty key, along with, some better drugs/scene & the essence of hacker spirit: curiosity. My story is a bit long, but Iam willing to share if it is of interest or possibly even of help to someone. It is a horrible state and not easily solved by someone deep in that hopeless state.
It works, that's true! It's just not designed or built to a very high standard (and I expect the arbitrators of the internet to build to a very high standard) ... So I'd say it's a quality issue.

Massive assumption that it was built by an external team. But I'd hope so :)
> People confuse cause and effect here. These places become so great because of the people that move there.

What’s your evidence for this? It’s more plausible that immigrants come to rich places for the potential to make money.

I don’t know about the Netherlands, but Silicon Valley arose in America during a time of historically low immigration. 1920s immigration reforms caused the foreign born population to drop from 15% to under 5% by 1970. Bill Shockley was born in London to American parents but raised in America. Six of the “traitorous eight” that founded Fairchild semiconductor were born in America. All the founders of Intel were born in America, same for AMD.
You’re totally ignoring interest rates which since 1982 have trended downwards significantly. Combined with inflation this is why properties have gone up in cost. A home will be priced based on the monthly payment the buyers are willing to make and that includes principal, interest, and taxes. As interest goes down, principal goes up. In general this is good as more of the buyers monthly payment goes into equity instead of bank profit.

You can sell your home and get loads of cash and buy a smaller place or rent. Many people “downsize” when the kids are grown and often move to lower cost of living areas. Also, your home is an asset. You can borrow against it. Considering you have not had a monthly payment for nearly 20 years you’ve had ample opportunity to save more money and upgrade your property if you’ve wanted.
Writing out the code to generate this may not be easier than using templates, but it is not really harder either. I think it mostly looks a little different.

The real benefit is using this bootstrap modal component within your app, since it is just a regular function call. You can leverage your editor "goto definition" and static type checking within all the functions make up your web sites/apps HTML.
The point of making the dictator unaccountable is not what he can do, but to whom he can delegate.
