Sure, how about I drop a 30 second "door knock" before I blow your life to smithereens because I feel like your 10 story building might be hiding a few kalashnikovs? Feel free to evacuate to the few hundred meters of free space in the world's largest open air prison. The simple fact is: this is colonialist ethnic cleansing and the only reason it goes unchecked is because of historic Western guilt uncritically favouring the Israeli state for geopolitical reasons.
Not sure what I do differently. But I do get banned after a few minutes making an Instagram account without phone or Facebook verification.

Not to mention that Instagram is useless for business of not linked to a Facebook acc.

In my mind the main use case is someone that doesn't have all that much battery range. They could buy a long range battery, but it would cost a lot more than the range extender.

If you don't have a long range battery, you might have to stop every 60-80 minutes of driving to charge. That will get annoying pretty quickly, especially since it's not like a smaller battery takes all that much less time to charge.

So I would expect the long range battery market to be quite big, and a range extender would have a good chance at grabbing many of those users.

Even if gas stations are somewhat uncommon, you'd only need to find one every 200-300 miles, and the worst case scenario is just that you go back to pure electric mode. You could also fill up a 5 gallon can for another huge chunk of extender range.

A single tank could save you an hour of waiting to charge.
Using it everyday too at $work, also used Slack and Gitter (and FreeNode/IRC FWIW). Quite happy with the current Element UI. They have slowly added features and fixed issues. I tried a beta some time ago with... topics? Rooms grouped in some sort of topic I think. It was really buggy, but I forgot about that I haven't seen it yet. So I assume they are doing some A/B testing, trying things slowly and seeing what works.

> Every single time matrix comes up, people make this argument

it's often the same group of people too... Andrew_nenakhov "forgot" to mention it but he develops a XMPP client and likes to pop up in the comments ofpost on Matrix to complain

edit: I'm not really taking a side on either XMPP or Matrix, I wish for both to succeed but I'm currently disappointed by both. I'm just getting a bit tired of XMPP fanboys spewing FUD every time Matrix is mentioned
Oh yes, no ends of fun with this.

The article mentions "Industrial IoT", but applications of time-weighed averages in industry are much, much older than the term IoT (or "Industry 4.0"). It's the cornerstone of recording data from industrial controllers and sensors, and as a functionality, it's built into most of the relevant industrial tooling (e.g. historians[0]). Support for time-weighed average and other means of retrieving and analyzing such compressed data is included in core industrial protocols like OPC Classic and OPC UA.

As the article says, it enables data compression - but the article is mistaken (or simplifying too much) by saying data points are retained only "when the value changes". In typical implementations, data is retained when rate of change changes (i.e. first derivative). As long as the data points fit on the line, you can recover them all from line's end points with linear interpolation.

There's some more sophistication involved in this, too: for example, when configuring data archiving, you may set up "deadbands" - basically defining how thick the interpolated line is; data points that fall on this thick line will be considered as if they were perfectly centered, and not recorded. On top of that, most systems also track metadata like "sample quality" or "engineering units used" - there are rules specifying when to record a sample if its metadata changed.

All in all, it's an ingenious approach, but it comes with certain consequences:

One - what this article is about - when data is stored in such fashion, you need to use time-weighed aggregations (average or other functions) to compensate for some (usually most) of original data not being recorded.

Two, this technique assumes a single, continuous process being recorded. Imagine you're using a "smart scale" to record your daily weight. After a month, you give that scale to your partner. Right there you introduce a discontinuity; any data query that overlaps the period between your last stored (not measured, but stored under compression) measurement and your partner's first stored measurement, will return nonsense.

These two caveats sound obvious, but I've seen industrial project getting both of these wrong at some point.

I'm sure a columnist would find a way to make this work, but the typical journalist adapting a report from AP or Reuters won't.
Even the major papers have had some pretty serious gaffes in the fact-checking department in recent years. That's kind of the major complaint with modern media houses: they don't do their purported jobs anymore. Book publishers don't really edit and promote books anymore, they leverage established e-authors. Game companies don't make new games anymore, they rebundle old games with a slot-machine monetization system. And news media doesn't edit or fact check anymore, they fight for clicks.

Mmmm, those sweet, sweet clicks. Come children, we shall eat well tonight.
I have a 10 week old baby right now, he can absolutely stand on his legs if you hold him steady - but yeah, he has absolutely zero clue what to do from there :P Also he's got a kick that you really need to watch out for, strong little dude.
Those numbers refer to what a planar transistor would have to look like to achieve the same density. Of course nobody is actually using planar transistors anymore.
It's not only what I do after work, it's more what I do at the end of my workday. I make notes about the tasks I've completed, and write todos for the next day, relating to the tasks I'm currently working on.

I think this lets my mind feel more at ease with stopping for the day, as I have actionable things to do the next day, even if I didn't complete all my tasks.
I find that, if you enable all warnings, most as errors, and use clang-tidy and cppcheck, you end up with an incredibly powerful safe language. Now, combine that with some good patterns and avoidance of NIH syndrome, and you can get very far while keeping the huge amount of control and libraries that C++ gives.

Edit: And, of course, a lot of forced static typing and avoiding global scoped stuff. So, for example, you'd make a

struct Meter {
float value { 0.0f };
};
Meter wall_length;

instead of `float wall_length; // meters`.
> The key issue is that people don't want to pay $2/month to twenty different writers. They want to pay $20/month to a single organization which has a hundred writers, also known as a "newspaper".

...actually, I'd *VASTLY* rather pay a small monthly fee to a small number of writers I care about, than a larger fee for a collection of writers that I don't.

More to the point, I am doing that, and a fair number of other people are too. If baffles me to see someone advancing the argument that "people don't want to..." and then listing something which people are very much currently choosing to do. Many people want to do exactly that! (Although I think we agree that the number of people is unlikely to be enough to be truly disruptive.)

> Maybe Substack will go the Medium way and try to aggregate

Very possibly, but if so, I expect the people enjoying their current business model will simply migrate to a competitor. $5/month for a writer I truly love is a reasonable ask. $5/month split across six writers, only one of whom I particular care for is in many ways less attractive; I may be getting more writing but the writer is getting less.

Aggregation is not obviously the only business model that makes sense here, and I think Medium - and come to that, the news industry as a whole - shows off its weaknesses very clearly.

I think the real weakness of Substack is not that "nobody wants what they're selling", but that they have very little moat. Substack doesn't need to worry that Yglesias will realise that actually he hates making more money than the entire NYT editorial board combined and quits blogging to go back to the traditional media; Substack needs to worry that he'll jump to his own platform and avoid their fairly hefty monthly cut.
There were a lot of companies building on Twitter API back in 2010. Do you remember what happened to them?
“ The logic is simple: an individual writer is always relatively niche. Niche means small audience. Small audience means you have to charge more per person to cover your costs.”

Except, with the Internet you don’t have physical/geographical constraints for distribution and suddenly a niche audience, at a global level, is not so niche. And it makes it a viable model, a thousand people paying $5/mo and all of a sudden you are making more than most journalists AND with much greater freedom of expression
> Do you use Windows, macOS, iOS, Android?

Their answer to this might simply be "no". There are people who just wont touch devices that are shipped with code / programs that don't respect the privacy of the user, unless installing free software to override the stock proprietary system is an option.
Yep noticed that. When I first saw ROC and that tiny, Olympic style flag, I had to investigate.
>Of actual open-source options: Gitter

Gitter was bought by Element, it's effectively a Matrix client now.
I hate to say it, but that sounds a lot like agile!

I had a very similar experience building a scheduling app for a UK freight company. They wanted a domain-heavy platform where they could manage their fleet of locomotives and wagons, with a lot of computer assistance.

The product owner was a gem. Once he warmed up to the process, we'd get him in a room and he'd talk and talk and talk about everything he found difficult. I mainly worked on the project alone, and bit by bit we addressed his issues. The issues grew more and more specific, until about 3 months post-release, where he came in and had nothing left to add. There wasn't even a wish list left. It was done.

This was where I came to agree with the agile 'small batch size' approach. Mistakes come cheap and fast. Most mistakes are usually communication issues, rather than technical. That's not to say that requirements were changing while writing code - it's just that we had good feedback loops, and a short phase had us fixing the real problems faster.
Stability is so relative. Comparing my portfolio to 1 year ago. My dollars and euros lost value, all my crypto is worth at least twice as much. I don't care about stable if this is the long term game.

They'd object, either while the MSC was being drafted, or during the FCP (Final Call for Proposal) period. If the Spec Core Team voted to merge something which the community didn't believe was aligned with Matrix, then they'd appeal to the board of the Foundation (i.e. the Guardians), who are legally obligated to ensure that the only things which get merged into the spec are aligned with the stated mission and values of the project (as per the Mission and Values sections of https://matrix.org/foundation). If the Guardians fail to adhere this, they would complain to the UK non-profit regulator, and the foundation would get fined/dissolved. The recourse of the guardians would be to either get the Spec Core Team to change their mind or to replace the Spec Core Team to get back in line with the mission. The process for doing this is laid out in the Articles of Association of the foundation: https://matrix.org/media/2019-06-10%20-%20Matrix.org%20Found...
Book authors have been getting advances against future sales for a long, long time, so it's hardly novel. I'm not really following the the concern.
This makes no sense. Open source doesn't collect my personal information. (Except when it does, which is bad behavior.) Anyway, the law is capable of making reasonable distinctions where necessary.

RegExr is really a quite useful example. So, some kind of JavaScript program, you'd like to use sporadically. Docs on the other hand are downloadable since forever.
In the short term? Perhaps. They might just develop their own proprietary OS - they already design custom CPUs!

I imagine it would depend heavily on how large the liability was. I expect individual components would begin being replaced with "certified" commercial alternatives. If not existing ones, definitely new ones. Remember that they make money by selling to customers who would also be subject to the same rules. Look at healthcare, aviation, and finance for concrete examples of the effects (both negative and positive) that red tape has on software and IT policies.

There's an entire FOSS ecosystem and the vast majority of it is composed of small-ish slow moving projects. The tech industry is also an entire ecosystem full of small and medium sized players. Even if behemoths such as mainline Linux and AWS somehow survived unchanged I would expect a much greater chilling effect on smaller players that couldn't afford to take on such risks. New companies and software projects would become very difficult to get off the ground (healthcare is a good example here). With few to no new entrants forward progress would slow to an absolute crawl.

All of this has downstream effects. Fewer consumer devices running Linux would mean even less hardware support. Security related liabilities would almost certainly mean more vendor locked hardware. Would companies like Purism remain viable (or even legal)? The steady stream of new FOSS users and contributors would almost certainly dwindle.

Depending on how such regulation was written, could open source contributors themselves become liable for a freely provided product?
I think the article doesn't say that the counterfactuals are not useful, it explicitly mentions they can be used as recommendations, as in "do not forget to monitor your disk space".

What they say is that counterfactuals stop the search for the root cause. Not monitoring disk space isn't a root cause of the filled disk. The root cause might be "application has suddenly written too many logs". This gives another set of counterfactuals, like "if your application was configured properly, it would write less logs". But it also gives an option of continuing the search for the root cause, which might be, for example, "there is a bug in the application which triggered the log writes".

I think the point of methods like 5 whys is not to stop at the first set of counterfactuals and deepen the search.
> we need to have an agreed starting point, and by historical accident we've all adopted an estimated (likely slightly incorrect) birth year for the founder of one of the world's major religions. It is hard to pick a culturally-neutral starting point

There are some astronomical cycles that could be used as a neutral reference.

For example, due to the precession of the Earth's axis, the star which is the North Star changes over a 41000 year period. So we could pick the time when the axis was pointing most closely at the star Vega, 11000 years ago, as the epoch.

Fair enough, it's true that they didn't start from scratch, but iOS today has evolved far beyond those original borrowed elements and is now much more than just a kernel and some early shared user space code. Even if that were not the case, it is still surprising that a company with Apple's resources would continue to favour writing new parts of iOS the same way 14 years after its first release.

> Yvonne Calment is imputed to have committed this fraud starting in 1934.

But France as one of the global powers has a very low crime rate in the 30s and the Calments are notable from their region not random unknown. If you think about it, the whole thing doesn't make much sense. Yvonne Calment should somehow have decided to replace her mother for sixty years including twenty while her husband was still alive for unclear reasons (a far fetched motive involving taxes was only found after Zay started pushing his theory) successfuly fooling the French state.

The whole thing doesn't make any sense. I don't understand how Zay was published (I mean, I do, it took him a decade to find a bad enough journal but it's sad) and I don't know why serious people are wasting their time arguing with him.

At this point, I just wish the genetic analysis were done to close the whole thing.
Thermalizing neutrons is also what the moderator (typically water but can also be eg. graphite, like in the infamous RBMK reactor design) surrounding the fuel rods in a nuclear reactor is for. Neutrons fresh from a fission reaction are too fast to reliably induce additional fissions before escaping and being absorbed by the reactor walls.

I don't agree with your representation that sanitisation of isolated surrogates constitutes "corruption". As a high-level point, when passing a string from your component to an external one, the external component receives a sanitised copy of your string - the original string is not modified in-place. So you still have access to your original string if you're relying on the presence of isolated surrogates for some reason.

For fairness, I will link below to your concrete example of "corruption", noting that you claim it will render Wasm "the biggest security disaster man ever created for everything that uses or opted to preserve the semantics of 16-bit Unicode".

https://github.com/w3ctag/design-principles/issues/322#issue...

I'd argue that the fundamental bug here is in splitting a string in between two code points which make up an emoji, creating isolated surrogates. This kind of mistake is common and can already cause logic and display errors in other parts of the code (e.g. for languages with non-BMP characters) independent of whether components are involved (again, I emphasise that no code using components has been written yet).

EDIT: I should also note that if it becomes necessary to transfer raw/invalid code points between components, the fallback of the `list u8` or `list u16` interface type always exists, although I acknowledge that the ergonomics may not be ideal, especially prior to adaptor functions existing.
And when you watch it do not expect an action movie, it is more of a brain tease asking the 'What if?' question in a pretty effective way. I liked it a lot, but most of the people that I recommended it to did not and found it boring.
A few key differences with other OSS companies that IMHO are positive:

1) Element or other matrix components do not require a copy right transfer. That means Element is hard to re-license under another license than its current one.

2) The license for Element is Apache 2.0. A fine choice for any OSS project looking to maintain a healthy ecosystem of contributors for decades to come.

3) The ecosystem has a diversity of stakeholders and contributors outside of Element the company maintaining various components, integrations, etc. It's an ecosystem that already serves many millions of users.

4) Not all the Matrix components are under the Element umbrella (see 3). Element is probably dominant in this community but it's based on merit rather than ownership. E.g. the Matrix foundation is mostly run by people outside of Element. Even the Element apps have contributions from outside Element the company (see 1).

5) Decentralization is at the core of the Element sales pitch. They are unlikely to want to walk back on that; or even be able to do that without damaging their credibility. For better or worse, that's what they are selling and stuck with. And they seem successful with it too. Hence the investment.
The parent is largely correct.

In addition, Iran is financing and using Gaza as a proxy war with Israel.

I wouldn't call the IDF "100% humane", as they deliberately shoot reporters, but they are fighting a defensive war to avoid being pushed into the sea - there is no peace treaty with their neighbors.

Arab countries have had decades to offer to resetttle Palestinians and Uighurs, but not a peep.
Why would they fear detection in the first place? This activism against those that don't want to be vaccinated is the best argument not to get vaccinated in the first place. Just stop propagandizing your own opinions. See that yourself are immunized and be done with the
topic. Eat some chocolate, paint a picture, search for a hobby... Without this bad activism the willingness to get a vaccination would probably be even higher.

That article makes it seem like private servers unconditionally sends metadata to official servers (is this really the case, seems odd?)

Other articles mentions sending metadata only to servers you have users from (which of course can be a problem, but at least is explainable).
Bloggers have been sued, yes.
Pandora.com, which launched in 2000, predating Spotify by 6 years, did a really good with discoverability. That was actually their primary feature - customizable radio stations, that you'd seed with a specific suggestion, and then further curate with a thumbs up/thumbs down. If you put in some time and effort, the stations would get really good at knowing what you liked, and would introduce new music. Spotify's radio feature is a poor shadow of this feature. (Soundcloud's is even worse.)

Because it's music, and not written text, and thus on in the background, having an 80/20 (or whatever) split for old/new music was really great for discovering new music that's similar.

TikTok solved discoverability for brief video clips, but they demand full attention. Basically the opposite of music.

Discoverability for the written word is a bit more complex, especially for long form articles.

(Pandora's backend implementation irrelevant here. Pandora predates the popularity of ML, so I presume there was a lot of human effort going on behind the scenes to make it work so well.)
