Wasted as in not fulfilling its potential even a little bit.

Mathematica is a very niche product. It isn't even very relevant in academia or in engineering. But it could have been if Wolfram hadn't hobbled it with unproductive restrictions. It could have had an audience of millions, and that audience would have brought it more value than a single company is capable of creating through a community.

Just look at Python. It is just a language. And a not particularly good one at that. ALL of its value comes from the community. Compared to Python, Mathematica isn't even a rounding error in terms of value created.

Imagine if Mathematica had been at the core of the last 15 years of data science, machine learning and whatnot? Imagine if the work and the value that went into the Python ecosystem had instead gone into Mathematica. Imagine if even just one of the many things Mathematica can potentially do well had become the go-to way for doing things.

But it didn't. Because Mathematica is fundamentally incompatible with the way communities work.

Mercedes dominating isn't because Newey lost his touch. The Red Bull cars have been in the top three for all those seasons.

The thing is, especially early on in the V6T Hybrid era the Mercedes engine was miles ahead of everyone else. There was simply no other engine capable of winning championships.

The first few years Mercedes was running the engines downtuned to lose some performance, because they felt the gap so huge that it would make the sport look bad if they were running a second a lap faster than the second team on the grid. With such a gap the FIA would also surely intervene fast. Artificially keeping the gap smaller, and only turning up the engine when needed gave Mercedes easy wins, while keeping the FIA away from intervention.

The fights became closer when the other manufacturers started getting more performance out of their engines.

Last year Red Bull won because the FIA changed some aerodynamic rules. Everyone expected that the changed rules would favor Mercedes and Aston Martin who were running low rake. It turns out the expectations were false, the new rules impacted Mercedes and Aston Martin hugely and the teams running a high-rake setup didn't lose all that much performance. This gave Red Bull a edge which lasted until around Silverstone, when Mercedes brought upgrades to fix the performance of their car.

The championship lead built by Red Bull was just enough to win the title in the end with some controversy in the final two races. There never were rumors of cheating anywhere.

I spent about $85 (AUD) on mine, it's a 5.83-inch tri-color (black/white/red), 648x480 display. For that much it came with the interface board so I could wire the display to my microcontroller easily enough.

I think that's reasonable cost-wise for my purposes (I'm making a status display to go inside my white-build gaming 'rig' to look shiny). Red takes about 12 seconds to refresh, AFAICT I should be able to get sub-1s black updates. You can get 7-color versions for about the same price but the refresh on those is very slow.

As ever it depends what you want to do - If you want a 2-inch tri-color display, in a format where you can attach SPI wires easily, you might get away with $20 AUD. You can find small greyscale eink displays very cheap (sub-$1) like this - https://www.aliexpress.com/item/1005003555154992.html

But you'll need to find some sort of interface from the ribbon cable to whatever wires you need.

If you want full-color, fast-update e-ink/epaper, that's just filtering into the market AFAICT, and it's much more pricey. I can find a 31.5 inch full-color epaper display for about $2200(US)!

Getting your hands on equipment to make identity documents is physically difficult, requires lots of deals, is costly, and is limited to a few people.

Replacing this with an electronic system, where access is guaranteed via leased lines to many locations, with sloppy physical controls... and a back-end that more than likely has several holes due to misconfigurations, last-week exploits etc

> How do I get a job within the EU Commission that will give me the opportunity to make millions for myself?

Simple! Be born into the wealthy elite or have very close ties to them (entrenched old money families) giving you access to enough funds, connections in the party and media, to campaign, advertise, win elections, and brush off all accusations of corruption and cronyism that could stick to you, while lying your way to the top by telling the rabble everything they want to hear (affordable housing, healthcare and education, lower corruption and taxes, higher wages and pensions, etc.) and once you're at the top, do none of those things and instead scratch the backs of those who helped you get there by giving them various tax breaks, lucrative government contracts, bail out their industries/companies, etc., and blaming external factors for making things worse for those who voted for you (Covid, Putin, China, immigrants, scalpers, terrorists, the boogieman, etc.).
I don't think there's such a thing as thermal transfer inertia, at least at the level of individual atoms (or molecules) within a fluid. In the inertial reference frame of the fluid, each molecule just has its own kinetic energy (and maybe excitation of electrons or whatever) representing its current temperature; I'm not sure what physical state at the molecular level could capture "how rapidly the temperature had recently dropped".

At the macro level, one can come up with ideas. Convection currents within the fluid, and in the air touching the fluid, maybe; though, say, once the hot water has cooled from 100°C to 35°C over a period of—what, ten minutes?—I'm pretty skeptical that there would be so much inertia in those currents that they'd persist, and persist strongly enough to accelerate the 35° to -1° cooling, enough to beat the head start of the water that started at 35°.

Maybe the initially cool water forms some uniform layer of very-cool water at the top (which, being very cool, doesn't exchange much heat with the very-cool air above it; an ice layer would be an example of this), which is held together by surface tension or something; whereas with initially hot water, that layer is not uniform and there's more mixing (and constantly-created convection as a result)? I have no idea if any of that is realistic. If so, it would suggest that shaking a cup of cold water (perhaps after a few minutes in the freezer) would work as well as having it start hot.

... After writing the above, I saw that (a) infogulch below has the same idea, (b) Wikipedia has an anecdote appearing to confirm it[1], and (c) the article doesn't seem to mention shaking, stirring, or otherwise agitating the cup.

[1] The Scottish scientist Joseph Black investigated a special case of this phenomenon comparing previously-boiled with unboiled water;[9] the previously-boiled water froze more quickly. Evaporation was controlled for. He discussed the influence of stirring on the results of the experiment, noting that stirring the unboiled water led to it freezing at the same time as the previously-boiled water, and also noted that stirring the very-cold unboiled water led to immediate freezing. https://en.wikipedia.org/wiki/Mpemba_effect

Just look at Python indeed. As you say it's a much worse language than many others that were equally available to anyone. And yet somehow it's at the the core of the last 15 years of data science, machine learning and whatnot.

If Mathematica had been open-sourced twenty years ago it wouldn't have taken the place of Python. It probably would be even more niche today - and worse.
Density and freezing outside in could have a pressurising effect too.

Because domestic corporations agree to work under domestic law, which a country created for a reason, in the US's case pretty democratically, and those laws align with things like individual rights, tort law etc.

An app owned by a foreign government that in no way subscribes to these values gives them freedom to do a lot more shady shit that would have consequences domestically, but don't as a foreign government.

But judging form your comment you don't really see any value difference in Chinese Communist Party values (and laws) vs say Facebook's values (and laws it obeys), so perhaps there's not much to talk about. I do see a difference.
It's nearly indistinguishable from a passport, not a national ID card (at least as implemented in other EU states).

The closest thing in Ireland was the "mandatory but not compulsory" Public Services Card and the related MyGovID, until it was ruled unlawful to require a PSC for access to government services.

There really is nothing like a mandatory national ID card in Ireland.

> I didn’t spend more time looking for more and I’m not interested in defending myself.

You just want to throw out accusations without evidence and you're complaining about "climate alarmicism" not getting enough scrutiny?

> Scientists that want to report inconvenient results are terrified.

This is an oft-repeated claim by people engaged in climate denialism, but it's a lie. A conspiracy theory without evidence. Where are all these terrified scientists? Who has been sanctioned for presenting contrary views?

A friend of mine was a climate sceptic. He started a PhD looking at glaciers and ice cores. He was expecting to experience some friction pushing back against the climate orthodoxy, but after looking through the data he changed his mind. He realised our models of the climate were consistent with the evidence.

Consider: if your "terrified scientists" theory was incorrect, and actually scientists did believe that the standard models are correct, wouldn't that state of affairs look identical to what is actually occurring today?
>After four days, 25 000 fake visits from customers had been registered with Facebook. But they had neither shut down nor warned the owners of the made-up pharmacy - Swedish Radio News' reporters. When the reporters log into their account, they see that Facebook has stored the type of sensitive information that they say their filter is built to delete again and again.

>The question that the reporters then asked themselves was whether or not Facebook even has a filter that works in the Swedish language. One of the pharmacies that Swedish Radio reported on say that they cannot find any warnings from Facebook on data transfers that have taken place. The other has not wanted to answer the question. According to state investigators in the USA last year, Facebook only filtered in English.

That also ate a lot of small healthy business pie in the market. I have mixed feeling about this. Do you think a company's R&D worth sucking a chuck of opportunity for small companies? I don't believe the niche vs. mass is less overlap. Imagine the market where there were no excel/spreadsheet/word. The customers of the market is spoiled by cheap/free/network-effect-koolaid plans just for sake of growth.

Hi, I happen to work on Google's Maps JavaScript API, and we actually take great pains to avoid breaking our APIs as much as possible. We take very seriously the implications that breaking changes can have for websites all across the internet, and know that many sites are not under active development.

This page covers the breaking changes from the last few years: https://developers.google.com/maps/deprecations#completed_de...
(Keep in mind that the top portion of the page covers features still in the deprecation period - meaning they still work. And that this page covers deprecations in other APIs like Android and iOS.)

My favorite: the deprecation period for v2 of the Maps JS API lasted 11 years after the introduction of the v3 Maps JS API.

Happy to hear about experiences to the contrary, but I thought a little insight might be appreciated.

That is oddly specific and rather appealing.
I mean I may be wrong about this. Still I don't see evidence that it was clear on that day that Saddam Hussein was not responsible in any way. Saddam Hussein had motives to act against the US, did so in the past, and I really doubt that they had conclusive evidence Saddam Hussein didn't and would never work with Al-Qaeda.

The very job of the DOD is to have such attack plans in the drawer. That's all I'm going to say on this.

While that's certainly the common case, the heat map suggests that at least some people on reddit are using 'trumpwit' as a pejorative, which I quite like.
While R is not a great language, it's a great language to work with. It has a huge ecosystem of libraries and a very active community. It's unmatched for statistical analysis (even by python), so it does great for data science.

I'm sure Mathematica could be great too, but I'm not sure how big of a community it has.
There has been a slow trend to hardware virtualization and moving drivers to userspace. The issue is that often the required hardware support (SR-IOV for example) is locked behind premium SKUs and it is trickling into consumer producsts very slowly. As such OSs will be very slow to embrace it fully.
It's easy enough to look up federal tax revenues during that period and see they were indeed revenue neutral. There's nothing dubious about it - it's trivial to check.

'trumpwit' is wonderful.

In 11th-grade 'Honors' Chemistry, we ran the 'Which water freezes faster' experiment outside in ~0℉.

Cold water developed ice first.
Honestly, Azure DevOps is a solid replacement. The integration is really good and the "Boards" software really feels like they're eating their own dog food. Their Wiki software is Markdown stored in a Git repo (unlike Confluence's mess). It's fast, permissions are relatively intuitive and fast, etc.

It's worth a look if you're evaluating.

JetBrains Space is another alternative, but I have no experience with it.

I don't believe a word. The three scenarios used to promote the benefits have some big stumbling blocks that can't be solved with simple credential storage.

> With the EU Digital ID wallet, the bank can request the necessary credentials from the applicant. He or she selects them, and in seconds they are verified by the bank. The process even includes an eSignature that signals the applicant’s agreement.

This seems a bit off.

As a US citizen living in Sweden, my bank also wants to know if a customer is a US citizen, because special regulations apply.

For the above scenario to work, the EU Digital ID wallet will have to store citizenship information, including potentially multiple citizenships.

Sweden recognizes the State of Palestine. Will the EU Digital ID wallet allow storing that information?

> The student can use her EU Digital ID wallet to access, for example, the diploma she gained in one country and have it accepted instantly in any other EU country.

That's ... also odd. That's not how it works now. A diploma in one country doesn't necessarily translate to something directly in another country. Quoting https://www.uhr.se/globalassets/_uhr.se/bedomning/informatio... "A recognition statement is a document that shows what your qualification corresponds to in the Swedish education system. To prepare the statement, we review your education documents."

An app storing credentials isn't enough.

> With the EU Digital ID wallet, the person can provide trusted proof of age and nothing more.

Bars and nightclubs also gather names to help spot people who have been banned, and will also share a list of banned people with other bars. They also gather this information to spot VIP customers.

They are't going to want to give it up.

In practice it will be like a a go-away-cookie-banner button. The bar's system will ask for more information, people will press the "confirm" button w/o reading, and the bar will still get demographic information. Those few who do read and say "no" will not be allowed entry.

If preventing this sort of information leak is important, then make it illegal to collect more information than is needed to verify age, or restrict what can be done with that information.

> Billions of people regularly use mobile apps, so the process will be familiar to the vast majority of citizens and businesses.

An odd statement. The population of the EU is less than 1 billion, so this refers to the world-wide population. But world-wide, billions of people don't regularly use mobile apps.

A better statement would be the number of people in the EU who regularly use mobile phones. https://newzoo.com/insights/rankings/top-countries-by-smartp... says for Italy that's about 75% penetration.

I assume that more direct comparison wasn't used to avoid talking about what to do for the people in the EU who don't have or don't want smartphones.
Yes - JIRA is almost a textbook example of lock in. Moving a large company's workflow would mean months of disruption.
