> I don't know that it is "wrong", just unexpected. I suspect most people expect all math functions to be purely implemented in numerical terms, so finding string manipulation is surprising/interesting.

You kind of got me thinking now. The decimal representation of a number is really a string representation (in the sense of a certain sequence of characters). Hence rounding to a certain decimal is essentially a string operation. You can of course do it by (say) dividing by 10^whatever or something else in some numerical fashion, but the more I think about it, the more natural it is to just think of the whole thing as a string.

Or you could flip it around and consider that the string manipulation can also be described numerically so whether you consider the operation as a string operation or a numerical operation is sort irrelevant. It's just a point of view.
It seems to fit under "interesting new phenomenon" but annoyingly enough people hit "flag" when they could have hit "hide" so it disappears.

Now we get to watch the same story get repeatedly resubmitted (bbc.com, guardian.co.uk, times.co.uk etc), commented-on and upvoted ... then flagged off by the minority. But hey, at least we get to see the latest DerpCorp S-1 filing!

> Water has lots of extremely non-linear behaviours!!!

Is caused by a special property of water? Or is it just the discontinuity arising from taking 0°C ice to 0°C water?

If it's the latter it applies to all solid to liquid transitions (entropy of fusion).
The art of memory: mnemonic techniques
It seems to just be layman shorthand for storing (not huge) integers as binary isn't lossy.
Trump, the Brexit band and Bolsonaro (you could add Salvini to the list, as well as other leaders of the populist right that have not achieved power but have been close, such as Le Pen) have the same origin: austerity and neoliberalism have pissed people off in most of the West, enriching the rich while the middle classes wane or stagnate. The political establishment have made a good job of adoctrinating against the left (I mean the real one, not the likes of Hillary Clinton) so people have seeked refuge in the populist far right. If different countries share a host of economic and political factors, it's not surprising that the results are also similar.

Putin and Erdoğan are different beasts, they have been around for much longer. They are just good at consolidating their power.

I don't know much about the Hungarian situation.
meanwhile I'm the exact opposite. I've been using the firefox dev tools too much that using chrome on someone else's machine is something I feel like I have to put up with.

That's not me saying Firefox's tools are actually better though, there's still a number of weird quirks or features that could be lacking, while also having features I can't find in chrome that I also take for granted
From TFA:

"LinkedIn is also the only major American social media platform not blocked in China because the company has agreed to censor posts containing delicate material."
That's the first thing I'd try, multiply by 10^digits, round, divide by 10^digits. Thanks for the link.
The majority of tourists to Bali are from Australia. Bali is the closest to home they can go without going to NZ (similar to Australia) or staying in country (ignore Papua New Guinea as too dangerous).

Planes make Australia a lot more viable, since it’s such a huge sparsely populated island that even a lot of domestic travel is better in the air. Bali and Indonesia’s various small distributed islands are much more dense, but island hopping by boat alone is also slow and unsuited to a lot of economic development.

Countries like Australia and Indonesia would take huge hits if air travel was a lot more expensive, much more so than America.
I got the same anti Japan vibe talking to thirty plus years old postgraduates from China but as I expressed to them I was hopeful that the younger generation would be kinder. Doesn't look like that's happening soon enough.
The actual situation is this: Wright does not control those bitcoins, because he is not Satoshi Nakamoto, just a conman.

He tried to explain the fact that he can't control them with the nonsense story about blind trusts, which the court soundly rejected for being a very obvious lie.

The court never decided on whether or not he was Satoshi Nakamoto, as both parties are happy to proceed on the assumption that he is.

Overwatch (and a few other games) its also kind of a social thing as i regularly play with my brother and sister in law who live at the other end of the country, its probably the closest ive ever come to enjoying a "sport"

Electronics, i just enjoy repairing broken things, it doesnt really matter what the thing or issue is, i just enjoy solving the puzzle if you will

Music, i dont play an instrument or anything but unlike many people i spend time just listening to music, not as a background to other tasks but actually sitting and enjoying it or looking for new stuff

Travel, i tend to spend a good amount of that time we all spend idly browsing the net to look for info on places i plan to travel to. In recent years i go to japan once a year so i spend time looking for things to do/see when im there, it may sound excessive but anyone whos been on holiday with me will tell you that it pays off
When was the last time devs took time out of their day to create detailed bug reports with crash logs and context? Telemetry done right is just a way to surface bugs properly.

Each has their pros and cons. My favorite features in FF devtools which are missing from Chrome are CSS diff and the advanced filtering in the network panel. Chrome filtering only works on hosts, while FF can filter in query strings and other sections of a request.
If you just want to be able to install unsigned extensions with neither the extra bugs from running a beta nor the telemetry, you can use the far less advertised "unbranded builds" of Firefox [1] instead.

I can try to answer any questions you might have.

The article highlights two main contributions of Arrow.

One is a question of how a society can make collective decisions. A classical answer is "utilitarianism" -- if a collective decision makes me happy more than it makes you sad, then we should do it. This requires society to be able to be able to measure exactly how happy something makes me and how sad it makes you. What if we can't make those kinds of measurements? Arrow shows that (under reasonable assumptions) we're stuck. There is no good rule to decide.

His other contribution was to "general equilibrium". A set of markets are "in equilibrium" if we can find prices so that supply and demand are equal in every market simultaneously. Do such prices exist, even in theory? Arrow showed that the answer is yes.
> That is fine, but it doesn't answer the question how Librem is purportedly solving that problem.

By not supporting WhatsApp, it forces the user to solve the problem that he/she makes a very bad decision with respect to his/her privacy.

Putting aside for a moment the fact that the most significant reductions in emissions have been generated by free market activity. You haven’t proposed gentle market steering and incentive creation, you quite literally suggested the “phasing out” of air travel.
You're right. A carefully curated social media account that you only use for travel, is a much better idea. Follow a few safe people, post a few harmless things, and before any trip, log out from your usual account and switch to this one.
In real life basically nobody who isn't walking around a nuclear disaster site, preventing a Russian submarine from becoming a nuclear disaster site or doing dumb things in a lab dies of radiation poisoning though. You just have a higher chance of getting cancer later.

There was probably tension between Diane Green and Sundar Pichai.

The general struggle for Google is the difficulty in choosing a strategy for serving both

1. Enterprise customers with custom / manual / labor intensive needs

2. Fully automated products and processes for a wide spectrum of users who need to adopt to Google and not the other way around

To sell big Enterprise contracts, Google needs to listen to these customers specific needs and promise solutions. I don't think Google has this capability in its DNA. This must be very frustrating from someone like Diana Green that is used to operate a company in a different way. Could be the reason that she left her role.

Unfortunately there are specific alloys of aluminum that are used for aircraft, and some that are totally unsuitable for aircraft.

Other than the web socket support in Chrome, the FF dev tools are a billion times better than Chrome now. I cannot work without the css layout overlays from FF dev tools. Makes working with grid layouts insanely easy.

I believe the problem is not so much about finding and flagging criminals, but treating the reasons criminals act like that.

Maybe girls do -- do the same. Say 20% of girls do the same, that takes those girls 'off the market', so there's more competition and less supply of potential 'mates'.

I mean it sounds like a black mirror episode but, there could come a day where nobody leaves the house and everything is done in a VR world, including relationships and sex. Of course that might be healthier than what's going on now, at least there's some actual socializing, not sure if it's a healthy alternative to the real thing.

My point though is it seems a lot of 'incel' behavior is driven by reddit/4chan (the seedier side of reddit, there are some good parts), so I think maybe 4chan/reddit culture plays some role. Probably also group think as there are groups devoted to incels and giving voice to their anger that no women want them.
Boris Johnson has a proven record of lying (he was even sacked from The Times for fabricating a quote).

Why assume his veracity in his quotes about the future of the UK?
Economics is an imperfect field, but a major source of criticism of it is that many people fundamentally object to the idea that you can ask "is" questions about the economy. The only proper questions are "ought" questions, and since economics is mostly about "is" questions, it's automatically suspect.

There really were a group of economists that fit the "license to be bad" stereotype, such as Milton Friedman. But Arrow was not one of them.

>I get your point, and I can see that you get the feeling of judgement from my post, but that I think you are adding.

Not at all, the BigMac/MacDonalds was only an example of something everyone knows about, given exclusively to make a layman's comparison, not to start a debate on free market rules, banana republics, regulations or affordable dietary preferences.

If you prefer, we can use as reference example - say - any other "service" chain, let's say Starbucks (probably a little less ubiquitous than McDonalds).

They make an effort to clean and keep tidy the premises, dispose of litter properly, and put the cost of that in the prices of what they serve, without any need to make a separate fee for that.

The weasel attitude is when Uber saying "for complete pricing transparency" calls a plain raise of price a fee as if it was an added service, a fee, by definition :

https://dictionary.cambridge.org/dictionary/english/fee

is "an amount of money paid for a particular piece of work or for a particular right or service" so logically the income derived from a fee should go directly to cover costs of this particular service (which instead is implied).

I think his first point about carbon capture probably deserves more attention. It's likely the most sellable strategy and it also doesn't depend on the location where it is carried out. It has the benefits of possibly producing some goods that can be used and there is prior history of this working. If we look at the Paleocene–Eocene Thermal Maximum we see a similar increase in global temperatures due to carbon dioxide release, albeit over a much longer timeline. But we also see a drastic reduction of those carbon dioxide levels. One theory as to how the global CO2 levels were reduced is algal biosequestration. Can we duplicate this at an industrial scale? We're already promoting the growth of algae unintentionally with fertilizer runoff, could we do this intentionally in a location that would minimize harm in order to offset carbon emissions?

There’s a difference between “contacts” and being a witting or unwitting spy.

Having foreign contacts, despite current furore, is not a crime, or improper. Now if you’re doing bad things, that’s obviously a crime and will result in disqualification, but simply “contacts”? No, that’s no reason for DQ.

Fairphone 3 Launch [video]
I went 2-3 years ago and really enjoyed it, there is so much to see and they have a lot of unusual exhibits.

My main gripe, which I did feed back at the time, was they had a wide selection of vintage computers and consoles running but there were no instructions. It’s a long time since I’d used any of them and had forgotten much of even the basics,;they also had Spectrum with the SSD type libraries but again no instructions on how to load and use the games. That meant you could look at them, try and type a couple of things in and hope you get lucky, then move on to the next item feeling frustrated.

The museum is continually evolving so I hope that something has been done to help what I felt was a fairly big shortcoming. I appreciate it’s a lot of work creating cue-cards for each one but as you’re encouraged to have a play around it would greatly add to the experience.
> Assuming 300 mph.

I think that's a very generous assumption. Typical small engine light aircraft cruise at 70-120 knots (80-140 mph). Wikipedia[1] suggests 211 mph as the current electric speed record (made in 2017). I doubt typical aircraft will be as optimised for speed as the one that holds the record. Increased speed causes exponentially increased aerodynamic drag, so if you want to increase range, slower speed [than your maximum speed] is the way to do it, not faster.

I think the best way to think about it is as a symbolic representation. We have processes for manipulating symbols to achieve the correct results. Purely numeric (binary based) operations just happen to allow for some quicker shortcuts but sometimes lead go lost information.

I use Postman a fair bit, and looking through my history it's mostly playing with 3rd party APIs to see what format they return and how they respond to query params and such. So it works for that purpose, since those generally won't have CORS restrictions.

It probably won't work for testing of your own API endpoints for, say, a SPA, though, which is likely to have CORS. But for local testing where I control the backend, I mostly just rely on printing responses to the terminal anyway.

You can revert to a count-based performance target, and test for compliance based on parcel weight
