> And while some outlets described the co-signers as experts in climate science, most are not. As noted in an analysis below, a significant portion of the co-signers are either engineers or professionals in non-technical fields. Only 10 identified themselves as climate scientists.

So 10! climate scientists argue against climate change? Still looks like there is an overwhelming support for it in science.

Learning is so much more efficient and effective when helpful experts are available to consult. When students are taught 1:1 by expert tutors their typical performance is literally 2 standard deviations better than students taught in a class. https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem

Ideally, if we could afford it, this would be how everything is learned; students would progress several times faster than they currently do.

This is one of the reasons that computer programming is such a joy to learn about. Have something you’re stuck on? Go ask on IRC (or stack overflow or a mailing list or whatever) and get an answer from an expert right away, instead of hunting around blindly for a few days.

When we build communities of people who all “cheat” together by helping each-other learn things fast, critiquing each-others’ work, riffing on each-others’ ideas, etc., everyone gets to the cutting edge much faster, and the whole field marches forward.
No conspiracy theories please. DNSSEC is operated by a non-profit called ICANN which manages its key-signing-keys in publicly recorded ceremonies comprised of community representatives from each continent. If you believe Google and Mozilla have legitimacy to govern cryptography affairs in the third-world, then by all means continue supporting the status quo. Also anyone registering novelty names should be aware of the risks.
This article is so full of Linux jargon, it’s impossible to follow unless you’re deeply steeped in it. Is there another source?

Trasferring or requesting lumens on keybase is incredibly easy and very cheap. Turning the lumens into fiat and vice versa isn't so easy at present.

Actually, it's obvious to me that this is the future - we want to share money in the same way and with the same ease we share thoughts and images ie inside chat systems and on social media. You don't need crypto to do this, but it's the best way of making a system anyone can join and trust.

Libra is going to be big unless it's artificially stopped, and that's my view, even as someone who would much rather see one of the current cryptocurrency systems win rather than a new Facebook invented thing.

If we hadn't ceded chat and social media to walled Gardens we would have solved this years ago.

Free software, free society: Richard Stallman at TEDxGeneva 2014
Big megacorps suck at innovation. Their internally developed product innovations are typically crap.

This comes as a surprise for companies like Facebook because they were once internet startups. They still see themselves as youthful and innovative. Wearing T-shirt or being casual may correlate with innovation, but there is no causality. The founder/CEO had success with one big idea that turned into success. What evidence there is that they can recognize and repeat the success multiple times?

They can successfully refine and expand their original idea and grow it, but their internally developed 'disruptions' are crap just like any random pitch.

Microsoft, Facebook, Apple, Google, Amazon buy new ideas, then use the economics of scale and network effects to make it success. Amazon has expanded the idea of internet retail from books to everything, including data centers. Apple finds success in design and branding competence. Google is still search and advertising company.

> The marginal gains in performance aren't justified compared to the amount of energy you end up expending.

Come on, we’ve been through this before. At least for the past 10 years if not much longer, performance improvements have not actually improved performance, they’ve improved developer productivity.

If you create a language that’s half the speed, but developers can program twice as fast in it, it makes sense to use it. Processing power is much cheaper than a $150k+ developer. Also, being first to market can yield outsized gains on competitors.
Depends. On Windows and Linux, ~nobody complains about Qt applications. On Mac, users do complain because some details aren't exactly right.
As an open source developer, I have mixed feelings about this.

Yes, Microsoft seems very keen on keeping Windows compatible even with ancient versions of the OS. New stuff usually is optional and APIs that behaved strangely in Windows 95 still behave the same way in Windows 10.

In Apple land, APIs may change their behavior whenever Apple deems it necessary. I ran into issues because of this with almost every macOS update since 10.8. And I see that even big players like Adobe keep running into compatibility issues all the time.

On the other hand, I'm spending just a few hours per week working on my project [0] and I manage to support an app that now runs on 10.5 through 10.14 and on three different CPU architectures with a single package. So no, I don't think you need to "throw 100 programmers at it" to get a working macOS version.

Another factor is that if you move countries some of your "purchased" movies disappear because you only "purchased" the right to watch them in territory X. While DVDs also made a half-hearted attempt at artificially preserving market separation with "zones" (I guess to continue the natural market separation that came from NTSC vs PAL and friends in the VHS days?) that could be worked around easily enough.
It did for me 2-3 times, and I was puzzled. I tried a 3rd time and it worked.
We have got to stop framing companies as evil for improving efficiency. No one is handing out medals to farmers who refuse to use tractors or programmers working on punchcard mainframes for “bravely increasing employment through inefficiency!”.

If we move into an era of problems due to low employment it’s the politicians that need to fix it, and not by attacking companies who are using the tools at their disposal to reduce costs.
Most hardware will hang if you program it incorrectly, even if it isn't advertised as being turing-complete.
Oh man, I just realized that my super-sensitive trackpad reorderd my words again. I was trying to say that Ruby gets "dumped on" by other developers. Not "dumped" as in swapped out.
Oh, I can shed some light on that !

In another life I did a stint in the subtitle industry (right around the glorious DVD boom and before the arrival of Blue-Ray).

Execs from distributors would sit down in a room once a movie had been subbed and played around the UI to see if "every language can be selected". How to spice up that job and make it look like indispensable ? Become an UI expert in the shades of faux shadow TIFF pictures overlay and timing in sound loop in menus. The fact that magazines were grading DVD's menus and UI also helped. "It's part of the experience". From then on you could not not provide fancy menus.

The funny part ? We had to purposefully disable built-in functionalities (soundtrack switching, subtitles switching, scene skipping, etc.) to enforce some "entertaining" loading times (and the usual anti-piracy scheme). So that the exec can sit in the room discussing for three hours how a menu DVD should look and sound to "give a mood". Rinse and repeat, you got a job.

Fun fact: the whole operation relied heavily on DVD shrink which we used to remove those limitations. Some took the habit to introduce hidden code to disable stuff or still allow skipping.

I am a bit bitter about it but I acknowledge that for most people it's part of the experience and it's expected. But forcing it on people who don't like it ? Bummer.

edit: I don't remember the name of the major software used to produce DVD menus (it was a tool chain anyway) (sonic something ?) but it was horrible compared to flash and flash mx from the mid 2000's. Think: timeline, b-frame based loop, on a slow media, still frame for background, simple transparent overlay TIFF files to render highlighted menu items, the editor was basically a vid and audio track editor with loops and skip points. No code. Mac and Windows versions not compatible.

Adobe had a good hobbyist software but there were small showstoppers problems I can't remember.

Anyway, it went all downhill really fast as the money needed to get a studio on track to do the authoring went from hundred of thousand of euros for hardware to a PC with early NAS and cheap HDD. A guy could set up his own subtitling and authoring studio on a dime. But you needed connections with distributors to make some money.

Windows users are used to UIs from the 1990s. Linux users are used to 100 different types of UIs and bask in the glory of diversity. Mac users are trained to care.

Addendum: the kernel remained 32-bit until Snow Leopard.
Why I think this is relevant to HN: Oculus Quest is a new standalone (cable-free) VR headset, whose popularity in was to great extent driven by the game BeatSaber, which is popular because - like any dancing game - there was a way for a community to sideload custom songs to dance to. The newest ToS update explicitly kills off song sideloading on Quest, and because of that, a lot of people are talking about sending back the headset for refund. It might turn into an interesting case study of intellectual property concerns possibly ruining a pair of good products.

(Disclaimer: I did bought Quest recently, 90% of the motivation was to play Beat Saber with custom songs. So I'm personally disappointed about this too.)

I don't know but people have made that saying with probably one data point and people like us want some one shot solution to every problem we have in life and that's why such quotes gather momentum. In reality these do not have any substance at all. You fail fast or fail slow, each have its advantages and disadvantages, sometimes severe, I wouldn't want to hurry and fail in my nuclear energy startup. So please take everything with huge grain of salt when it comes to preaching from the (confirmation) biased peoples.

What exactly is nontrivial in parsing XML? Any popular computer language has plenty of libraries for working with XML.
Interestingly, it's amazing to me that many SQLite libraries in the Go ecosystem don't support these mixed/flexible data types in tables.

If you read back a set of values and one of the fields in a row doesn't match the data type given by the column, the libraries will error out.

One library that works correctly is github.com/gwenn/gosqlite, which checks the data type of each field of the result set (per row), so handles things gracefully.

Carbon UI framework has been deprecated for 12 years. Cocoa has been available since the first Mac OS X version, so ~20 years ago, and it's still be main UI framework on macOS, and it will still be for years.

There is a conscious "capitalist Socialism" afoot in Japan.

Rather than have a large, explicit, government-run social safety net, the society instead embraces inefficiency in the name of keeping unemployment low.

When I was stationed there in the military in the '90s we marveled at seeing people in company livery out directing traffic in the parking lot at the grocery store.

There were inefficient layers of distribution for prodcuts, and cute little trucks running around making deliveries, so that everyone has a job.

Their "bridge to nowhere" infrastructure projects are legendary.

They also have a gazillion little bars where you buy your own bottle and return to the same place to chill out every night with the colleagues.

Cassette tapes and faxes? Sounds par for their sort of quirky, introverted course. I kinda miss it.

This is entirely by design.

Apple doesn't want you to build an app 20 years ago, make no updates to it and continue to sell it as though nothing has changed in the time since.

Their website is compromised of mostly broken links, the design is dated and it is showing reviews and awards from 10 years ago.

Clear to me that they couldn't be bothered to put any effort in at any point in the buyer's journey so I say good riddance to them.

Thanks for reminding me about systemd. I just used "systemd-cgtop", and yes, I see 38 cgroups, one cgroup for each service/user. But 88% of the memory is used by one cgroup: user.slice, for all the program started by me under the desktop. So I'm not sure it can save a lot of memory on container-less desktop.

Surely good for all servers.
I think that's just wishful thinking. I'm from Melbourne where cycling is pretty common (although not as hectic as in Holland). The cyclists here are still pretty rude.
Oxford Street (London's busiest shopping street) is closed to normal traffic - buses (and stupid exceptions) only. It's still massively busy with buses. At any given time I'd estimate you'd be within eyesight on 8 buses at least.
> That's because the OS developers have placed value on security over performance.

No, that is mainly because nobody knows nor cares about me personally.

As for your example, i already addressed it with that last part in my message:

> Note BTW that there is a difference between "i find performance more important" and "i do not care about security at all". I do care about security, but i am not willing to sacrifice my computer's performance for it. I simply consider performance more important.

The browser is a case where i'd accept less performance for better security because it is the primary way where things can get into my computer outside of my control. However that doesn't mean i'd accept less performance in, e.g., my image editor, 3d renderer, video encoder or whatever else.

In other words, i want my computer to be reasonably secure, just not at all costs.

If you want to become rich, put a small amount of money in the stock market, and then go into hibernation for 100 years. When you wake up, presto, you’ll be wealthy.

This sounds implausible, but it’s basically the same process as inherited generational wealth.

The Fourier transform and its generalisations are so underappreciated. I've been trying to understand where the speed savings come from and suspect it has to do with coprime harmonics.

I hope someone smarter and more knowledgeable will correct my understanding, but as far as I can tell, the logN savings in harmonic analysis comes from the exponential decay of harmonics in any real ringing system (a passive resonant chamber), because you can avoid "counting"[^1] the energy of subsequent harmonics as precisely as the fundamental frequency.

An excitation frequency of 400Hz will produce resonant harmonics at 800Hz, 1200Hz, etc. at exponentially lower energies than the fundamental. So essentially, you can skip measuring the totatives of the frequency bin you care about.

For example, to find the cause of excitation at 9Hz, you only need to count the energy at 1Hz, 3Hz, 6Hz and 9Hz. You can ignore the totatives of 9 except for 1, which are {1,2,4,5,7,8}.

So if you detect 10J at 2Hz and 10J at 4Hz, you can be sure that there was an excitation at 4Hz as well as 2Hz. Euler's totient function is multiplicative so you win if you do this simultaneously for coprime frequencies.

This is not my area, so math or signal guys please tell me where I'm wrong.

[^1]: "counting" happens by cross-correlating the input with a reference signal, which in Fourier analysis is a cosine wave at the frequency bin.

This already exists. If your bank's AML algorithm flags certain transactions, your account will be frozen, with no explanation (they legally can't tell you why they did it, it is an offense). You will be asked to produce some documents whilst they and potentially law enforcement investigate. Again, you won't be told why or how long it will take. Usually, if you haven't done anything wrong, you'll have no access to your money for 1-2 months.

Now, here's the kicker. Those flagging algorithms aren't very good. They don't work on any sophisticated social graphs.

They're based on a bunch of simple rules -- maybe you made a large cash deposit, or wired more money than usual, or received a bunch of small transactions (maybe you're selling drugs?). The flag is raised, the account is frozen and you're shit out of luck trying to get an explanation or buying things for a few months.

Given we still use banks, I'm sure "you violated our community standards" won't be the straw that broke the camel's back.

GPUs also do lossless transparent compression in some places for bandwidth reduction, at the cost of allocating some additional metadata. It's commonly called delta color compression. (And it doesn't reduce memory allocations, but it fits the theme here.)
