But that's not the current most accurate working theory? We have not detected any gravitons yet. So the general theory of relativity is still the top contender, with some cracks showing in it as well. But the comment is tongue and cheek, of course, mostly illustrating how we were ready to fire any academic who didn't believe gravity is a force, when the leading explanation at the academic is the GR explanation.

The idea being, is that perhaps some phenomena are multifaceted and complicated and climate study is the same. Moreover, it is compounded by a multitude of political and social interests trying to insert themselves into the discussion.

I can't speak for anyone else but I wrote a chess engine by myself without using all the tutorials/guides out there.

Because it's the challenge, just having something handed to you or Googling it just takes all the fun away, plus when you look at prior work you risk blinding yourself to other ways that might not work but are still worth exploring.

But that's for personal stuff, for business it usually makes sense to check what other people have done, otherwise you get what's called 'not invented here'[0]

Yep. I wrote a paper about memetic algorithms in the 90s, before it even was called memetic algorithms and before the whole thing was called AI.
Ask HN: Can Firefox be revived?
Since 2018 and management changes Firefox lost a lot of users. [1]
Firefox has now 3.67% market share.[2]

Mozilla is mismanaged, to quote another commenter from HN:

>Mitchell Baker (Mozilla CEO) makes $3 million a year, and Mozilla asks you to donate "to help a nonprofit organization".
>"On the same period, Firefox marketshare was down 85%. When asked about her salary she stated "I learned that my pay was about an 80% discount to market. Meaning that competitive roles elsewhere were paying about 5 times as much. That's too big a discount to ask people and their families to commit to."

>"By 2020 her salary had risen to over $3 million, while in the same year the Mozilla Corporation had to lay off approximately 250 employees due to shrinking revenues. Baker blamed this on the Coronavirus pandemic."

>This lady then goes on and on talking about "social justice".

>Also Google deal produces 90% of Mozilla's revenue. I would say Mozilla is really controlled opposition.[3]

Mozilla derives over 90% from it's income from Google deal.[4]

If we take all these points in considerations, it seems Firefox is in peril. It can either disappear, become totally irrelevant or do what its biggest customer dictates it to do.

If web becomes a monoculture and only one company will be able to dictate its features, than the future isn't exactly rosy for users and developers alike. We need Firefox and other rendering engines and browser to have a healthy competition.

Is it possible that some company with deep pockets forks Firefox and hires what it's left from its development team to further develop Firefox and improve its market share?

Can it be in some big company's interest to push for web competition?

Since many big corps derive their incomes from the web, it should be. If they let someone control the web, it can be detrimental to their businesses.

I think; There could be other factors, but this is the main one

I'd guess that, on average, the bulk weight of the press loosely determines its maximum pressure... Just because it needs a certain amount of steel to confine and direct that pressure without damaging itself.

Over time, the engineering gets tighter and with less excess. You know that phrase, "anyone can make a bridge that stands up, but you need and engineer to make a bridge that just barely stands up"
It probably becomes an economic issue, especially given the bigger your press is, the less people are going to need it for something.

Spitznagel’s entire strategy is designed to lose all of the money allocated to it unless there is an extreme market event, hence why it should be a small allocation in a larger portfolio. It’s pointless to compare it to SPY or whatever.
I’ll happily take my quiet, small, and cool MacBook and number crunch in a data center infinitely more powerful then your laptop. Guess that makes me a shiny iPhone idiot.

Relax, no one is forcing you to use Apple products.
They did open up their hardware to other operating systems: they engineered a feature into their secure boot system which allows a Mac's owner to attest (with physical presence required) that they'd like to run a kernel not signed by Apple. That's the door Asahi Linux uses. It isn't there on iOS devices, even those also based on M1.

Everything else you're asking for would require them to spend significantly more money and/or engineering resources on supporting the port, and that just doesn't seem like a thing Apple's senior management would go for.
I don't think that the economy of wood is worse in the long run. It is quite much faster and cheaper to build with, and as long as it isn't allowed to be wet for long periods of time it also lasts indefinitely (there are wooden temples that are 1300 years old), and repairs are usually faster and easier than similar in concrete.

Do you have a source? How valuable is knowing the serial number of an ATM dispensed bill?

Very little cash is deposited into an ATM. Any time I’ve deposited cash I’ve never seen it scanned (it goes into the drawer).

And if it were scanned at multiple points think of the cash in a register at a store? How many transactions does it go through before getting scanned again? Especially smaller bills?

Seeing that a bill was dispensed at an ATM on Market St in San Francisco then deposited by a restaurant in San Mateo 1 month later tells you what exactly?

Most of the non-cellulose elements (the ones nneeded for life) are in the outer layers of the tree.

Modern forestry machines strip off the bark and a little of the phloem (the living layer) in situ.

But yeah, there is a slow loss. Partly made up by the micrometeorite dust that falls everywhere, and in some places by dusts from other places. For example, the Amazon rainforset is replenished from the Sahara.

Deciduous forests are better at this. Deep tree roots break down rocks in the subsoil, recovering minerals that way, and leaf fall creates a realtively rich soil. Undisturbed virgin deciduous forests with deep soils have near 100% mineral recycling. The micrometeorite dust makes up the rest.
>I think this happens for the same reason they win their Nobel in the first place

You are absolutely right. As they say There is a Thin Line Between Genius and Insanity. The very intensity of their out-of-the-box thinking which got them the Nobel prize in the first place is also what makes them prone to go off in many other directions without regard to Social Standing, Ethics and Morality.

IMO, this is not a fault but Genius applied to the wrong beliefs/ends which does not invalidate any of their other achievements. I will take the Genius with all their faults over the Common Average any-day.

This guy is a great engineer, I’ve been following his stuff for a while now. But there are unfortunately several fundamental limits which mean this type of system will likely never reach human level performance in a real world system.

I work in robotics, specifically compliant and modular actuators, similar to the ones in the video.

As I see it, (and many others in the field) One of the biggest issues in robotics is a lack of good artificial muscles. The need for them is that in a robot which can work with people you want it to have both high enough force output and power density to actually move things, but you also want the robots arms to be back drivable; you want to be able to move its arms by an outside force. For welding robots you want the opposite, zero backdriving and zero backlash.

To get back-drivability, good torque and reasonable power density, you generally can’t use spinning electric motors. You need to hear them too much. This is why Boston dynamics use hydraulics. It’s also why Boston dynamics is unlikely to ever sell you an Atlas in its current form because those custom hydraulic actuators make the system so unreliable and expensive, even a mining or gas company would struggle to justify it.

The short and long of it is this: if you want a robot that can do the things humans can do, like play soccer and rock climbing and knitting, then you need muscles like humans have.

So you need artificial muscles. There are a lot of different ways of making them. [1] the issue is no published technology is able to give you want you need to make a good analogue of human muscles.

The muscles in the video are (correct me if I’m wrong) soft fluidic actuators. These actually have pretty good potential, especially compared to things like piezoelectric actuators. But when taking into account how you would actually put these in a real world robot, problems arise.

But the main downside is you need lots of pumps and tubing to make it work, and it has limited maximum stress and relatively low actuation bandwidth. In a nut shell, to make these strong enough to do much useful work, you need them to be really big, and that means they can’t move very fast. There is a reason you don’t see any commercially available robots with this kind of actuator.

I really hope this creator can make his system do what he has set out to achieve. And perhaps he will be the one to figure out a new kind of actuator which does tick all the right boxes.

Conflict of interest: The startup I work at is developing a commercial product using a new kind of artificial muscle. So my views may be coloured by that.

[1] See this paper for a good breakdown of artificial muscles: https://sci-hub.se/downloads/2019-10-12/7c/zhang2019.pdf?ran...
Damn a $0.75 can is cheap even by Japanese standards, and I'm assuming that's a US-standard 12FL OZ can (bigger than Japanese ones too).
Say a companies directors are not trustworthy and you get a bad feeling from the way they speak about people around them. Later on, huge fraud is uncovered at the company. What does (rigorous or not) TA or backtesting tell you about the likelyhood of something like this happening?
Yeah, I was surprised too. They talk about a lot about the bamboo part but not at all about the glue part. And the glue part is certainly the most problematic one. Also, but that may be too much interpretation, you'll notice that the dirtier the place/the job; the more you see women on the pictures.
> 5 min at 100 degrees

That would make a bitter cup of green tea. Green tea infuses best at 80 degrees and the time is dependent on the tea.

Green tea taste follows a bell shaped curve, there is a small window of about 10 seconds when the brew is best, you got to stop it precisely at the top. You can use a thermometer and a watch, but the easiest is to just take a sip of the brew every 30 seconds.

Black teas, oolong and puerh can handle 100 degree water and are not as fussy about timing.

> Chaina won't attack it would be pointless and make zero sense they are more interested in building their economy

A prosperous China is indeed less worrisome than an unprosperous China. A big problem is that China's economy is a house of cards and if and when the Chinese people have to face the reality that the economic promises the CCP has made to them will not be realized, China becomes a big threat. An imminently defeatable one, but one that can still cause a lot of death and destruction before it is defeated.

That also ignores the cost of running the App Store. While certainly not costing 20 billion, storage, bandwidth, credit card fees, payout cost, tax handling (Apple takes care of VAT in Europe), app reviewers and engineering cost will add up.

The other thing I fee that‘s often overlooked is that paid app subsidize free apps.

Because that is the threshold question of any defamation case [1]. OAN lost that case and re-lost on appeal. Then in awarding Maddow attorneys fees, the court was saying OAN shouldn't have even filed the suit in the first place.

The question for you, the original question, is why would you consider her shorthand argument based on fact equivalent to what Alex Jones does?

> I believe the person meant "electromagnetic force" instead of "charge". Question remains.

But those are different things...

The question is answered by stating that all the other forces are explained by the standard model, with gauge bosons mediating their interactions, while gravity is currently best explained using general relativity.

The funny part is, of course, that we were ready to let go, without a severance package even I presume :-) those academics who did not believe that gravity is a force. Given that the leading theory states that gravity is indeed not a force.
Why? Some forms of this work pretty well in lots of countries, it doesn't in others. As with all its in the details but straight out saying no is just ignorant.

The trick with Apple Pay is that supposedly you have already accepted Apple's TOS and they already have your cards so you do not need additional registrations.

Wow, you also solved the JSON issue. I've been wanting to implement Xapian as a server-side search server for Hugo. I believe by just creating the template using Hugo, it should be pretty easy to have it search the JSON. I've got quite a bit of work to do though to figure it out.
The coding aspect is indeed boring, but as you probably already know that is a very small part of the time a software engineer spends trying to solve a problem. I like watching streams for people trying to build software mostly for for the problem solving and to see how other people think through problems. It’s also interesting to see what people’s process looks like, which is not possible when you just see the final result (ie open source or pull/merge requests).

Twitch has now a category “Software and Game development” which is an interesting rabbit hole. Of course not every streamer is great and not everyone will like the same things, so instead of pitching the ones I like I’d suggest check out a couple of them and see which style you prefer.
I appreciate that "UK Anecdata" might be misconstrued as "Ukraine Anecdata" (and I could have been clearer that it was UKOGBANI or GB, sure) but in what world could "UK" encompass Poland?
I should have stated my definitions clearly, because I might be using rather unorthodox definitions of “wrong” DRY and premature abstraction.

Premature abstraction is premature at the time of abstraction. It aims to address future needs that may never happen. Wrong DRY is correct at the time of abstraction. It is wrong only in hindsight when a different need that is not addressed by the DRY arises in future. In that case, it should be easier to change the abstraction than to find duplications and DRY them. DRYing early also allows getting the benefits early until the needs change.
It doesn't need to. You don't put all your eggs in one basket. No trader expects 100% win rate, not even close.
> It still fascinates me why people take human-focused formats (SQL, shell commands in one line) and use them in automated programs.

I tend to assume that it happens because it is what's available, and possibly easier (at least in some cases, but then the lowest common denominator wins). Unintended and not quite appropriate use of technologies in general seems to often happen that way.

> Same can be said for HTML (it was designed for human writing/reading), but it's too late to change that. But SQL and shell commands can be fixed today in application access.

Well, HTML 5 includes the XML-based syntax, which is quite machine-friendly. And for running programs one can indeed skip a shell and just run it with provided arguments and environment variables when it's done programmatically. While to SQL there's usually no alternatives in relational databases.

Though I think even SQL isn't inherently bad: a complete, specified, and sensible grammar, together with a proper parser, would allow sane composition and processing, and exclude the bugs such as this one.
Or just vaccinate. Cheaper and better. (Try estimating the price of enough hospitals, employees and of course the sick leave for the patients. Then multiply with x in case people contract covid several times during life.)

I've been running a setup with Recoll and https://github.com/ArchiveBox/ArchiveBox for a few months now [1]. Each morning archivebox scrapes all new links that I've put into my (text-based) notes and saves them as HTML singlefiles. Then Recoll indexes them.

It's very fast and ~4 lines of code. It's surprising how often I rediscover old blog posts & papers that are much better than what Google yields me.

From my experience Recoll isn't very good at searching for aliases sadly.

Where did it work pretty well?
It feels like another important perspective might be missing here.

If you are building software that other people are expected to interact with, the bare minimum you could do is read The Design of Everyday Things.
One big reason why compilers don't target architectures is because you have to write codegen and an assembler for it - the first is hard and requires intimate knowledge of the ISA and the second is tedious since there are few assembler libraries at all. So you use an existing compiler infrastructure like gcc or llvm that does it for you.

For C++ specifically it's a great language for low resource embedded systems and widely used. There is nothing stopping you from using it today (responsibly).

A much more interesting road is languages like Java that have more intense runtime requirements like garbage collection. But Java has run in similar environments for decades - it just takes the right VM and some restrictions (usually, no reflection).

A very interesting project right now is Toit, which is pushing the boundary on JIT compilation on small devices.

Your comment is both condescending and wrong. Linux power management on mobile used to be garbage, but now you can get excellent battery life on Linux-friendly laptops, if you willing to invest time into tuning it. I'm typing this message from one such laptop (Lenovo X1C).
Yes, we are dogfooding pretty hard! We release a bunch of times a day and every release goes through a suite of >130 Rainforest tests for regression. We also add tests for every new feature we release, so it keeps growing.

It was a cool thing to write tests for testing the test writing interface :) That's one "level deep" - out of curiosity I was playing with how deep it's possible to go and it turned out at 7 levels things get too small to really make sense (terminal within a terminal within a terminal etc.), but there's no inherent limit.

And we can do this because we work on the pixel level - even though the terminal is a canvas element and it'd be hard/impossible to work with it using the DOM, it doesn't really matter for KVM.
I have as many (or more) siblings as you, and adhd. I got meds somewhere not too far before my thirtieth birthday. That is now well above 10 years ago and yes, it has meant a lot.

This is the first time I'm this specific about my background here but I thought you would like to know at least one other person here knows a little bit of what it feels like.

Good luck going forward!
There are many people in Germany, working as so called 'Aufstocker' which means their job is paying too low, so get government subisidies until they reach at least what they would get as (longtime) unemployed money. Imagine single moms, one or a few kids, working service industry. But also many other people, in low payed service industries, sub-sub-sub-contracted temp jobbing, and so on. This phenomenon is not limited to Portugal. Sometimes the kids get chromebooks, or tablets from whomever 'for free', but not everywhere. Besides that, there are other things to pay for in school, even if school itself is free. €400 is a lot for many, catastrophically so, sometimes.

A detailed analysis of Metroid II connected with a moving personal story. It fairly hihglights the games many qualities as well as its negative aspects. It does that by taking the game world very seriously. As someone who loved this game and played it a lot when growing up, I still found a lot of new thoughts here. I found especially striking how the mad "Maze of Murderscapes" inside the game blends into the mad social structure of modern life at the end of the article. What a fascinating read!
