To be honest, I didn't know they were supposed to remain stable until I saw your comments, so I guess they work well for me. There are only very specific situations where I get discomfort and they misalign for me, but a few blinks puts them back in their spot.
Motif and FLTK apps exist, but they are very, very rare these days. If you count Motif, you can as well count Xt and X Athena Widgets. FLTK isn't as old, but was AFAICT never widely used in any case.

Motif used to be the standard toolkit for commercial Unix applications in the 90s I guess, and you might still see it when using some expensive but minimally maintained software originating from that time.

Show HN: Updated wave method of building color palette
In colouristics there are several methods for constructing a color palette (color gamma) based on the arrangement of colors relative to each other in the color circle and, usually, having the same brightness. Harmonious perception of which is not sufficiently substantiated from the physical point of view.

The wave method of building color palette based on the relationship and color and acoustic waves, and also the concept of consonance (harmony) in music theory. More detailed description of the method is here - https://wavepalette.com/about/

A few days ago, the algorithm was completely finalized and posted on the site - https://wavepalette.com/. There is also a mobile application and ready-made palettes - https://wavepalette.com/palettes/

Far from an expert, but applying general high level engineering principles I would guess it's related with the accelerating complexity needed to get linear performance gains, especially as the lower hanging hardware fruit has been picked.

I know a bit about the meltdown/spectre bugs and that seemingly was the case there: essentially a software hack to get more performance out of literally the same hardware. That was done to increase performance, but of course there were unintended consequences that nobody foresaw or cared to look for. It's almost obvious looking with hindsight - no free lunch etc.
>+ Facebook/Zuckerberg will defy the gov.s and launch Libra.

They could try but they'll be doing so in the face of laws designed to combat money laundering and funding of terrorist organisations. This isn't remotely on the same level as what AirBnB were doing when they decided to flout local laws around rental properties.

>I think Zuckerberg has come (or already know) to the realization that these institutions "added value" is navigating the regulations/laws of the different countries.

That's what will likely make Libra a non-starter in most countries. Financial institutions have already invested significantly to ensure their business practices are compliant with both local and international law. They won't allow Facebook to start undermining that.
I think the GDPR is now mostly wiping out fax in Europe for anything important (notably, health services have been purging them for the last couple of years, and I think the financial industry is mostly calling time on them in the context of PSD2), but yeah, they've stuck around an impressively long time.
The traditional mechanical systems in automatic vending machines that tell and sort correct coins from wrong or fake ones are probably of the same class of mechanical "sorting" (rather categorization in this case) systems. "Mechanical coin acceptor" appears to be the established expression for it.

I have two questions regarding batteries I often wonder about. Maybe the wisdom of the HN crowd can answer one or both of them:

Is there a theoretical limit on how much energy a rechargeable battery of, say, 1 kg mass can hold?

Can a rechargeable battery be discharged and recharged and afterwards be in the same state it was before the cycle? Or is degradation inevitable? Again, I am asking for the theoretical possibility. Not real life challenges to implement it.
You're probably alluding to things like PXE or mDNS, or some proprietary industrial control protocols? This is true but deploying a VPN to cover them is a pretty high price to pay in operational complexity and security cost. There's usually other ways to address the task at hand.
> To the west, it sees its most talented engineers working in Silicon Valley. By pouring millions of dollars into Indian-made semiconductors, India’s government hopes to solve both problems at once.

It really can't. Considering the "rootless" nature of Indian urban life, education and society, both culturally and linguistically, the lack of "pull" ensures that any money you pour into its colonial institutions is only going to accelerate its departure to American shores. There is little precedence of such a deeply colonial state ever being able to help its subjects in a meaningful way (ironically, it was perhaps less so during British era).

People who think India (with literacy of < 80%) is the next China are too self-deluded for help.

You're not in general paid in "visa". You either have a bank account and can withdraw cash, or you can get paid in cash.
Now,if you're paid into your libra account (or indeed PayPal account, Apple pay, Google whatever) - then you're indeed at the whim of those companies use policies.

Visa won't stop your card over a nude Pic on Facebook - but Facebook might suspend your account and your libra over it.

Note that for example in Norway (probably Europe?) every card transaction is run through a check for money laundering and criminal/suspicious activity in real-time.

You touch your card, central authority can decline the transaction. (I have a friend that used to work on this system, implementing rules).

But they don't check your tweet history (although, I'm sure the intelligence services do, and I assume they have a secret, quasi-legal "terrorist" watch list that probably is linked to this system somehow).

Yes, activities where the goal is the movement itself, rather than getting somewhere, would be hampered. My point is that getting that precise control may be much harder, both technologically and in terms of user training. Maybe a gradual approach could be implemented.

The wording you used for your example is purposely unwieldy, but even so it would be still logically valid. It's perfectly valid as well to say that it obfuscates a particular point you are trying to make. However, as humans tend to have different priorities, and values a wording you prefer may be validly presented as obfuscating points other people see as more important.
"The famous quantum factoring algorithm of Peter Shor may or may not be a galactic algorithm. It is of course one of the great results in theory, ever. It has sparked funding for research centers on quantum computation that have promoted many other advances.

If and when practical quantum computers are built Peter’s algorithm will be one of the first algorithms run on them. Right now it is a galactic algorithm. But, perhaps it is the best example of the importance of galactic algorithms."

For a theoretical CS book, it is readable, with the concepts progressively introduced to the reader. Pretty decent work.

>Even with “intelligent design” the intelligence would have its own heritage and origin

Is this really a given? Certainly there must be something in the universe that "started it all" and has no origin of itself. Or, alternatively, everything in the universe has a history stretching back infinitely far, but that's equally incomprehensible and still allows you to perform the same "trick" (in this case: life has always existed).

Not saying that I believe in intelligent design, but in this case it seems to me that it does answer a question without creating any new ones.
Electric fences haven’t existed long enough for evolution to have encoded genetic responses to them.

> For example if you want to back up, you just copy the file or add it to git. If you want to do a diff you just do sqldiff on two files.

With Postgres, you run pg_dump on the database (which is a shell one-liner, only with slightly more arguments than cp) and that's even better for putting into git because it's a text file that git can diff natively and store efficiently with delta compression.

I mean for batteries in general. Independent of the technology.

For the spinning matter battery, the limit might be when the whole matter of 1 kg spins at the speed of light. I wonder if it matters how big the radius is with which it spins around the center?

For a non-rechargeable battery, I guess the limit is 1kg * c^2. As Einstein postulated that e=mc^2. And that guy was right more often then not. Is that also the upper limit for rechargeable batteries?

How long could a Tesla drive on 1kg * c^2?
Is your claim there exists no uniquely human trait as compared to other animals?

That's the same kind of reasoning that sent a mom of whose babies died to prison for decades. (I can't remember her name so can't link, sorry - it's a well known story of a mother getting convicted for double child murder because a doctor did some shitty statistics in court).

Sure, the chance is high. But if there is no conclusive evidence, then there's no conclusive evidence.

That might be enough for angry Twitter mobs, but I sure hope that it's not enough for court.

Maybe Japan? Haven't visited. But China has lots of terrible city planning and they are way too into cars. I lived in Beijing for 2 years and Beijing traffic is just the worse.

Beijing is also not a very good city to be a pedestrian in, as every major street typically has 12-16 lanes and waiting at intersections takes forever. It feels like walking along a motorway. Finding shortcuts throughs the alleyways of a city block is also really hard as many of them are gated. Same goes for any major Chinese city really, except for the ones with surviving colonial city centres like Shanghai. The metro is pretty good, but definitely not pleasant to use during rush hour, and changing lines usually entails a lot of walking around underground tunnels.

I have seen some code written by software engineers that was bad and also a lot that was good. They simply need to be taught how HDLs work which is conceptually simpler then something like C++.

I very much disagree that most issues are hardware specific. FPGAs all work the same way. What is different is the IP that can be ran on different FPGAs but that is generally a tooling problem not inherent to the problem domain.

This is not a browser feature, this is a JS-provided thing. IME, the browser smooth scroll is pretty neat, but website-provided implementations suck.
The only Cocoa API that has been deprecated in recent years is drawers. Apple is not going to suddenly rewrite their entire desktop apps and utilities in UIKit/Marzipan anytime soon (if ever - hell, they won't even rewrite them in Swift anytime soon), so Cocoa is well established and here to stay for a long time. So unless your app is entirely built out of drawers, I don't see how the mere presence of Marzipan can affect your long term business.
I think that’s more that developers want to make a decent living. The vast majority of subscription apps have a server side maintenance cost. As the platform matured and developers realized those users were going to stick to their apps for years without paying another penny, then it becomes untenable.
The vulnerability probably wasn't in the cards. That is, the cheater could not read the card RFIDs directly. It is more likely that he has been able to access, in real-time, the system reading the cards and storing the card values.
My company has an incoming fax line solely for bank notifications. This was an upgrade from the old system where I'd call and speak to someone on the payments desk.

I built a trebuchet once when I was 10 or 12. It was about as high as I was tall at the time, and it was on a platform with 6 wheels. I shot some of the neighbors' prunes into a meadow next to our house, and then when I went for a massive load of IIRC pebbles, shot myself straight in the face. I wobbled home, had a headache for 3 days, then tore the thing down.

Not sure what my point is - maybe 'careful what you wish for'?

But if you really need to see transactions everywhere, here's one:

When I give software away for free (which I do) or food (which I do) people give me something in exchange: their trust.

I also give my trust to other software developers.

Not caring of security is a breach of such trust. Same as giving someone some spoiled food.

You are thinking of Sally Clark:

https://en.m.wikipedia.org/wiki/Sally_Clark

> Clark's first son died in December 1996 within a few weeks of his birth. Her second son died in similar circumstances in January 1998. A month later, Clark was arrested and tried for both deaths. The defence argued that the children had died of sudden infant death syndrome (SIDS). The prosecution case relied on flawed statistical evidence presented by paediatrician Professor Sir Roy Meadow, who testified that the chance of two children from an affluent family suffering SIDS was 1 in 73 million. He had arrived at this figure erroneously by squaring 1 in 8500, as being the likelihood of SIDS in similar circumstances. The Royal Statistical Society later issued a statement arguing that there was no statistical basis for Meadow's claim, and expressed concern at the "misuse of statistics in the courts".

> as recently as December 2016 he was the senior author on a similar study that tried to discredit international health guidelines advising people to eat less sugar. That study, which also appeared in the Annals of Internal Medicine, was paid for by the International Life Sciences Institute, or ILSI, an industry trade group largely supported by agribusiness, food and pharmaceutical companies and whose members have included McDonald’s, Coca-Cola, PepsiCo and Cargill, one of the largest beef processors in North America.

I think this is enough for me to disregard that individual and anything he says about nutrition. If you want to eat processed meat go ahead and eat it. You can convince yourself it's healthy too. You can convince yourself sugar is healthy.
