If you want to simulate light at a physical level (even as simple as two projectors shining light at the same wall) then Linear Light is correct —- it is any time when your mental model includes ‘light’… It just works.

You are right though that schemes like sRGB are a better fit for perceptual brightness. As you say the slider works the way people expect it to and you don’t need so many gray levels. 8 bit linear light shows posterization at some levels and is shaded too finely at others. If you want good results with linear light and common tools you need 16 bits of grey.
> With swap, your system becomes completely unresponsive for longer than you have patience for, so you power-cycle it.

My entire life using linux (>15 years) never had a situation where once swap caused system to slow down, system eventually got back on feet. Usually, swap causes other apps to slow down, swap and put system in a state it can't recover from.

Maybe I'm mistaken but my rule of thumb is to never use swap unless I specifically need it. This means, for a default desktop OS, I would never enable swap. If we run out of memory, apps should be killed.

"Framing Jews’ achievement as a cultural trait erroneously spreads the belief that educational success comes from adopting the “right” cultural values. But Horwitz argues that Jews value education because 'it has worked for them throughout history, not because they are genetically or culturally predisposed to it.' ”

But isn't valuing education a cultural trait? It's interesting that she takes pains to claim it's not, perhaps because she's afraid of stepping into the minefield of explaining differences in achievement among other groups.
I keep on being seriously relieved that I've not developed fatigue. I have MS, and fatigue is a really common symptom. People don't get how much it can upset life, nor how little sleep helps with it. Heck, I don't really understand, but nevertheless, I tried to come up with a plan to deal with it. Realistically, that means being happy I don't deal with it right now and deciding there wasn't much I could do now to make it easier later.

The received wisdom was that for many years it was easier to make money from Apple customers. Despite the fact that there were fewer iPhones compared to Androids the theory was that iPhone customers tended to have more money and were willing to spend to get things. The Android ecosystem was also much larger and you had to test on more phones to get confidence in the performance of your app across the customer base. So from a developer point of view, you're solving a simpler problem for more money.

In practice actually iPhone 'fragmentation' is surprisingly bad in terms of how UIs would render unexpectedly on different phones - still probably easier than Android but levels the playing field a bit more, Android market share grew and went more upmarket, cross platform frameworks improved and the whole practice has become less common.

Most valuations these days are predicated upon market sentiment, low interest rates, rapid growth, and forecasts into future cash flow growth. Should any of these crash into reality, the proverbial faeces hit the fan, and the valuations disappears like the smoke and mirrors they are. Nothing grows 20% YoY forever. It's all unicorn farts and VC pixie dust powering these high flying valuations.
Sorry, but a system with that many caveats, is not the same thing.
A couple of excerpts for context:

"China is the home to some of the most interesting and innovative digital ecosystems and entrepreneurs. However, given the military civil fusion state, openly stated by China, all their firms must face a different standard, especially when handling, managing, or accessing data."

> What moral high ground do we hold now?

Vast amounts of ground, fortunately. How about the fact that we can have these conversations fully uncensored? That little thing known as freedom of speech, which is still overwhelmingly alive and well. I enjoy its use, aggressively, on a daily basis without persecution and have for decades uninterrupted.
Articles like this make me feel really out of touch. Honest questions:
has it become standard practice to write applications that don't
handle heap overflow at all because it's meant to be handled at the

the application that requested it sink or swim?
The problem that law was meant to address was that most of the debt being discharged came from a relatively small pool of students who attended very expensive or prestigious schools.

If they had set a limit for discharge to the value of the median cost of tuition, it might have prevented the runaway train of inflated costs in the education and perhaps even medical sector, outside of what was caused by malpractice insurance rates in the 70s.

Also, individualizing risk to the students irrespective of degree choices and economics without dutifully notifying students isn't ethical behavior, especially when they are responsible for the magnitude of the risk by not controlling costs or advocating for the value of the students they graduate.
well, that was fast :)

The bigger point to discuss. If twitter is under control of the US government. I have no idea if it is or not, it just seems to be the case.

You dont get to make the comment 'twitter is private, free speech only applies to government' because twitter == government.

The other consideration I had. What if the us government doesnt explicitly own twitter. They simply dont realize the us government has hacked access to moderate and censor things in a clandestine way? Now it's an even more complicated subject but wouldn't justify the stock market situation that brings me to the point.
The problem is with attribution of the problem to you directly.

People almost universally know that severe obesity is bad for them. You don't need to tell them.

There are many reasons people are obese. For me it was mostly a psychological issue. Doctors need better training in this regard, because telling someone to stop being lazy and eat well will almost never lead to them to improvement. Dieting, in the long term, it almost universally a failure. It just doesn't work. It doesn't address the right issues.

Yet, for doctors and those unaffected it seems like such a trivial thing that any deviation seems self-inflicted. They must be doing it willingly. They must be shamed. But it is never is that simple.

It is an attitude they constantly carry into conversations with patients. They need to take that attitude and throw it into the trash, because all it does is make the patient feel horrible about the lack of control they have over their condition that they supposedly should have, according to their doctor.
In a perfect world, we would have dense cities, we would have wild land that belongs to nature, and we would have farmland; and most land would fall into one of these classifications. While we might see "market share" fluctuate between these, a relatively stable population guarantees that we would not see a huge loss of wild land.

In reality, every state, every city, and every town are in a de facto competition for tax dollars, and there is no central planning. So instead of adding dense housing to desirable Burlington, we clearcut forests or replace farmland to add low density housing 10 miles away in a subdivision near Shelburne. That family that was charmed to move to Vermont by the shops on Bank st will end up driving to the nearby big box store in Shelburne instead. The traffic will get worse, local farmland starts disappearing because suburban land is more valuable on a square foot basis, and once all the farms are gone the process begins again another 5-10 miles out.

It's a vicious cycle, and it creates an ecosystem where most people can't even enjoy the city they came to love in the first place because they live miles and miles away (and good luck with traffic and parking)
One of my biggest disappointments as a parent was choosing the wrong neighborhood for our son. We picked one that we thought was going to have lots of kids, but it ended up not happening. It has some kids, but the problem these days is that a minority of neighborhoods have the critical mass combination of number of kids X number of free range parents. We can kick our son out of the house, but there is really no one else to play with. We've tried it, and the only kids regularly outside are 3-4 years younger, and he tried to play with them but got bored quickly.

It's really depressing as I am all for the free range parenting. But our location is just the wrong match of things to do around and number of kids :( In hindsight I would've moved elsewhere, although my wife moved when she as a kid and she is still scarred by that experience.

Our son is 13 now and we need to keep him in camps because the only other option is for him to sit at home and screens all day - last summer he had almost no camps, and we tried to get him outside, but he'd go house-to-house and see if he could get friends to go do anything, and it basically never worked. And if it did, they'd go sit on some swings at the school, chat for 30 minutes, and then the friends would leave.

Depressing as all hell. Pandemic didn't help the situation. When I was a kid, it was "out of the house" after breakfast, and then maybe stop by for lunch, and then "be home when the streetlights come on or if Dad whistles".

The realistic detail I remember from that movie is that the drones had plausible-looking reaction control thrusters (like those from missile interceptors [1]). There's a behind-the-scenes video that mentions the idea and has some (spoiling) shots from the film. [2]

[1] https://www.youtube.com/watch?v=RnofCyaWhI0

[2] https://www.youtube.com/watch?v=Lfg84vgO73Q&t=116s

== Tangential physics nitpick ==

In a scene (spoilers, [3]) where a hovering drone is firing its side-mounted autocannon turrets, the reaction thruster animation doesn't match what's needed to counter the torque from the recoil:

1. The drone begins by firing both port and starboard turrets forward--no torque from recoil here, only backwards force that is countered by the drone's gimballed main thruster.

2. The drone ceases firing its starboard turret to slew it towards a target directly behind it. Of the aft-facing reaction thrusters visible in the shot, only the starboard ones are firing. But this would exacerbate the torque of the still-firing port turret instead of countering it!

3. The starboard turret finishes targeting and begins firing aft, but the reaction thruster animation remains unchanged.

Of course, this level of detail already far exceeds expectations, considering that this all happens in less than a second, and that there's no impact on viewing experience when fast-moving effects don't stand up to frame-by-frame scrubbing.

I also use it, have been for about 6 months now and its been a joy to learn and work with. I really like the ability to use typescript and all its helpful bits and tooling for a domain as large as infrastructure on aws. I think it makes infrastructure more accessible to devs who have never had to look at a yaml file for weeks on end or had to learn some DSL that wasn't a general programming language.

One of the most spectacular examples of penmanship I ever saw was sitting in a meeting with a lady who could effortlessly write phrases and paragraphs in italics... cursive italics ! It was perfect in every possible measurement. (And no this wasn't decades ago, this is 21st century).

But I digress! I did also want to state that I disagree with the author's statement "Nobody writes it anymore".

Clearly the author has not met many doctors or lawyers or spent much time in Europe.

Cursive is very much still in use by all three of the above.

None of the games I play these days are CPU intensive so while I understand FPS is important to a large group of gamers I have never paid attention to it. Before clicking I thought "does frame rate really matter for Mario 64? How big of a difference can it make?" I'm absolutely blown away, I can't believe how smooth this looks. I don't know what else to say, I'm speechless. Stellar job. Vroom vroom.
> Correctness as I and my parents and grandparents learned is really just a matter of self-respect, I think.

Fucking weird angle on that imo. It's a skill with broad application but low impact for most people. The actual techniques for good handwriting aren't taught in school anymore, so people will have to decide to value it, seek it out, and practice it themselves. You might think they should, but if they disagree it doesn't indicate that they lack self-respect.

An almost infinite number of skills fit into this honestly. Kitchen knife work, drawing, whistle or sing a tune, phonetic alphabet, advanced mental arithmetic, basic carpentry, sewing, plant care, orienteering, bread baking, small engine repair, knot tying, etc etc etc etc.

Anyone can learn a bunch of these to varying degrees and they'll be frequently valuable through life, and potentially contribute significantly to identity and yes self respect. Which specific ones someone ends up with is pretty much meaningless though. I mean this kindly but there's nothing special about penmanship just because you value it.

Thanks, vouched even though I'm not sure your claim about "every major player" being out is correct (https://money.cnn.com/quote/shareholders/shareholders.html?s...). Still, easier to have that conversation elsewhere now that there's a general public conversation about it, so it's harder to hand-wave it away as conspiratorial.
It's such a financially convenient line of thinking. It's absolute nonsense. Both at face value and once you dig into it. Mainstream media is feeding us constant lies which work against our interests, destroy our ability to trust institutions and the government. Big Tech is clearly the biggest threat to our democracy.

Before Big Tech, we did not have such problems. This new narrative is pure self-serving propaganda, a figment of the imagination of corporate-funded lobbyists.

Free-market capitalism with freedom of speech is the recipe for economic prosperity. Has been for hundreds of years.

Some people will point to China as an attempt to show a counter-example ("Look at China, they're totalitarian and their economy has been booming.") but they conveniently forget the fact that China's growth has been happening during a time of general loosening of policies. The past 20 years in China have overall been characterized by an increasing tolerance for free-market capitalism and more freedom of speech compared to what it was before.

China came out of an extreme form of communism. Of course, any loosening would yield huge improvements! Also, they have over 1 billion people, of course any small improvement to even a small fraction of their population would have an impact globally.

The problem with the US and the west is not freedom of speech or the free market, it's our debt-based monetary system which is now based on soft money. The decline started in 1971 when USD became detached from the gold standard. It's no longer backed by anything; also, the growth in the currency supply has become unconstrained and the distribution mechanisms for all newly issued currency have been partially hijacked to serve corporate interests. The effects of this were not felt immediately. It's only in recent years that the negative effects of our soft-money system have become difficult to ignore.

The important thing to note is that no fiat system has ever survived more than a few hundred years. A monetary system which is founded on the endless debasement of its own currency is doomed to fail sooner or later. There has been hundreds of such monetary systems over thousands of years; not one which remains to this day. It has never worked and will never work in the long run. They're just pyramid schemes.

I think the issue with a lot of governments is: expertise and competence is expensive.

If you don't want to pay for that because the government is then expensive, fine, but eventually you'll have an incompetent government that is slow and still expensive due to the mishaps it leads to, for itself and it's constituents.
It needs to be, at least for some projects. Unfortunately, it's the organization, internal bureaucracy, and controls that fight it the most. Someone on hacker news said that governance is a glue you pour over an organization to keep it in the current, working form. Changing those mindsets, and avoiding a compliance group from squashing progress, is in my experience nearly impossible.
There's "30 bit" (10 bpc) displays, which have been around for a fairly long time. These are not HDR, but usually native AdobeRGB with high bit depth. The way that works / used to work is that when an application uses a 30 bit surface, it still outputs an 8 bit image which travels through the Windows GUI pipeline and it's the graphics driver which replaces it with the real 10 bit image on scanout.

I don't think any of the current TN/IPS/etc. PC monitors with HDR have 10 bit panels. HDR is achieved generally through sheer imagination (most) and less commonly through more or less (rare) rough local dimming, not by actually having a panel capable of anything close to HDR contrast ratios.

A look into Heptabase’s split writing experience
The worst part about web colour is that it's not even consistent. If you draw a PNG containing a rectangle with a given colour on to a page with background colour of the exact same RGB values, then it can look different.

Here's an example: https://incoherency.co.uk/interest/colour.html

And here's a screenshot of how it looks on my browser (Firefox 99.0, Ubuntu 20.04 LTS): https://img.incoherency.co.uk/3812

The square is a different colour to the page background colour despite having the same RGB value (#0cf4c7) but they look different. No amount of changing the colour mode selection in GIMP can fix this.

I opened the screenshot in GIMP and used the colour picker tool to see what colour my #0cf4c7 has turned into, and in the screenshot image it is #67f1c7.

Strangely, when I draw the screenshot in the browser, its colours stay the same, so obviously there is something you can do to the PNG that will make it render the colours you chose.
People speak of "the algorithm" as if it were an animal spirit or American god to appease and to implore. I suppose this is our zeitgeist.
In my experience swap to zram works really well.

I have 16GB of RAM in my linux laptop running Ubuntu and it isn't quite enough: Chrome, Virtual box, gopls and thunderbird regularly push it over the edge into swap death needing a reset to recover.

My first install was the earloom killer a user space oom killer. This has a nice desktop notification and when things got tight I'd get notifications about it killing chrome processes.

That made things liveable with but not perfect. I couldn't run Zoom without earlyoom killing it.

I finally added swap to zram and that has helped enormously meaning I have enough ram to run everything I need without the earlyoom kicking in regularly.

Anyway I'm just about to upgrade to a new laptop I can put more than 16GB of ram in, but I think I'll leave both the earlyoom and the compressed swap in place.
