A lot of Hacker News analysis of California reads to me like people who moved there 10 years ago and lack any context.

The shocking liberalism of California's approach to street-visible crime, homelessness, immigration, and drug use is a backlash against prior failed policies. The 80s and 90s saw brutally high crime rates. Gang activity terrified people. It felt like every single nightly news included some 8 year-old girl caught in the crossfire waiting to buy ice cream from an ice cream truck. Combine that with Satanism scares, the Polly Klaas case, and we got some tough laws. As kids in LA County, we were not allowed to wear red, blue, or Raider's jerseys to school. A classmate of mine was expelled for having a switchblade comb because of zero-tolerance rules against lookalike weapons. Three-strikes laws and enhanced sentencing for gang-related crime led to extreme prison overcrowding and the general hardening of the prisons themselves led to runaway recidivism.

It was pretty obvious those approaches were not working. So what happens? A backlash in the opposite direction. Addiction rates only got higher when we arrested people for drug use, so try something else. If you're not going to build housing and you're not going to have public toilets, exactly where are people who live on the street supposed to shit? Let them shit in the street.

This is neither progressive nor conservative. It's the same back and forth oscillating between two extremes and hoping you eventually discover moderation that all of American politics experiences because of the two-party, first past the post voting system. California isn't even really that progressive. It's public-facing culture is dominated by the hippies of the Bay Area and libertines of Hollywood, but those are hardly the only people. Mexican Catholics, all of the refugees and immigrants from Asia post the wars in Vietnam and Korea, and the huge flood of Orthodox fleeing former Soviet republics after 1989 make up far more of the population than any descendants of the English. These are hardly super progressive populations. It's only been dominated by Democrats since the mid-90s due to backlash from Prop 187 poisoning Latino voters against the Republican party, plus whatever residual strength remains in public-sector and trade unions. Throw in the relatively high proportion of success in performing arts rather than business ownership in making people wealthy and you get a pretty good atmosphere against the American GOP. It doesn't mean the average person there is radically different from the average person anywhere else.
The Seattle-Chicago line is operated by a single company. Europe has dozens of national operators. So any direct comparison is of course difficult to make.

To travel 3000 km on a high-speed train, Japan and China certainly offer the opportunity. Beijing-Guangzhou is 2230 km and operates at 350
km/h.

I feel this very strongly in terms of BIG (work) TRUCKS not used for work. Those big trucks with Marvel’s The Punisher themed graphics, flat/matte paints, military-inspired details (I’m thinking of a particular bumper style), and most of all comic inspired details: blacked out windows—so much easier to draw, so much the worse for actual driving. Main character syndrome in the worst way. Just go for a walk or bicycle ride or ride your motorcycle on a Saturday in the greater NYC area and you’ll know exactly how I feel

If I remember correctly I had created the math parts with the windows PowerPoint app and it was shown more or less correctly in the web app, until I double clicked on it and it completely broke; something like it being a singular element that wasn't editable at all when it should have been a longer expression, I don't remember the details. But I am pretty sure it wasn't just a font issue.

Curious about your hypothesis, I went on Tiktok and clicked trending. The top thing (clips from Superstore I think) had 16535 text comments on it though mostly stuff like

Sure, but… cities in the USA are thousands of km. Seattle to Chicago (the example given by the GP) are 2800 km distant. Those cities are slightly more distant than Lisbon and Warsaw. Chicago to Washington DC is almost the exact distance as London to Marseille (1000 km). Chicago to Houston, Texas is the same distance as London to Rome.

To go back to the first example, Seattle to Chicago is a 4 hour (scheduled, which already includes taxi time at both ends and a buffer for late departures) plane ride. Even a TGV running continuously at top speed (320km/h), with no stops, would take 8.5 hours to complete the same journey. Wikipedia tells me that the fastest start-to-end scheduled speed of a TGV is only 280 km/h, which would take over 10 hours.

Older wall clocks used synchronous motors which would literally move the second hand using the waveform from the A/C power. As loads on generators went up, the effective RPMs went down, causing downstream power to run at slightly slower than 60Hz. It was so heavily used that power stations used to run "fast" catch up on any cycles they fell behind at night so that there were exactly 86,400 in a 24h period to prevent clocks from running fast or slow.

Amusingly you'll see stories like this when power companies fail to maintain 60Hz on average over a day:

The Blowout No One Sees Coming
The distorting power of money. And then think: if it can distort our collective understanding of the world, could it distort our government, our elections, etc.?

The problem with capitalism is that it destroys democracy. Money distributes to a small group of people who then have overwhelming influence over the government, available information, and so on.

We also see that as money flows away from the poor, and the affordability of essential goods like housing, food, and healthcare worsen, those who should gain from democracy rightfully grow to hate it, and vote to destroy it (e.g voting for Trump).

We need a new economics.

Evaluating how much of instruction space we cover was indeed difficult.
Initially, we wanted to parse Intel XED's datafiles to generate a map of valid instruction space, but we ended up going for the simpler approach of computing coverage by selecting instructions randomly and from real-world binaries because of time constraints.

From Table 7 you can get an idea of how many instruction variants we cover (~1500 covered, ~700 enumerated but not synthesized, 744 out of enumeration scope).
Instruction variants correspond much more closely with the mnemonics listed in the reference manuals, and this is typically the number reported by related work.

> No human has run faster than a cheetah nor flown like an eagle.

No, but we have and regularly do move faster than any cheetah and fly higher and further than any eagle.

My point is that, to an objective observer, there are things that humans have done and can do that make us obviously separate, as a species, than any other animal on earth.

The scale of our combined efforts dwarf the efforts of other animals.
Especially when considering that, physically, we have very few advantages over other animals.

Arguing against that point is just playing mental gymnastics to say “oh actually humans aren’t really exceptional”

Idk what that might say about the “value” (whatever that means) of human life compared to other life.

A concrete example would be climate change. Humans have been pumping the atmosphere full of shit for a long time and it’s causing global climate changes. No other animal has affected the climate at that scale.

Bad or not, that kind of thing makes us humans exceptional.

So I've been reading

https://graphicscodex.com/app/app.html

and

https://mini.gmshaders.com/p/radiance-cascades

so I could have a basic grasp of classical rendering theory.

I made some assumptions:

1. There's an isometric top-down virtual camera just above the player

2. The Radiance Cascades stack on top of each other, incresing probe density as they get closer to the objects and players

I suspect part of the increased algorithm efficiency results from:

1. The downsampling of radiance measuring at some of the levels

2. At higher probe density levels, ray tracing to collect radiance measurements involves less computation than classic long path ray tracing

But I'm still confused about what exactly in the "virtual 3D world" is being downsampled and what the penumbra theory has to do with all thus.

I've gained a huge respect for game developers though - this is not eady stuff to grasp.

A Simple and Efficient Implementation for Small Databases [pdf]
When people talk about psychedelic experiences being 'mystical' (or spiritual etc.) they're normally talking about the feelings, experience, and sometimes visions of the trip itself. Strong trips really can make you feel like you've communicated with God, or with mother nature, or make you feel like all people are connected on a spiritual plane, or... whatever. They're not talking about the science of how it affects your brain.

And all the studies (that I'm aware of, at least) using psychedelics and therapy to treat mental health conditions don't use doses high enough for the kind of trips they can create those experiences - the goal is to have a strong enough effect that the brain and its thought patterns are more malleable than usual, but not so strong that the patient focussed on the trip rather than on the talking therapy.

It's definitely possible a patient could walk away from a session so impressed with its effectiveness that they describe it as magical, or even mystical meaning that it worked and they can't understand how it worked, but that's not at all what psychedelic users normally mean when using those terms.

edit: Actually, it's worth mentioning that there are other non-Western cultures using psychedelics to treat mental health issues, such as Ayahuasca ceremonies in various South American countries. I don't really know enough about these to talk about them in any detail, but I do know it's common for the people to take strong enough doses of Ayahuasca to have full, intense trips, and while I think there usually is a leader of the group who probably does some sort of conversations to help people with their trips, it's not like Western countries' talking therapy, and I suspect it's likely that some, maybe m many, people who find benefit from that sort of psychedelic experience are indeed getting it from what they experienced, thought, and felt, while tripping.
I believe there are two extremes. On one end you get a bunch of repetitive non-issues, while on the other end you only get issues about (say) bugs in FreeBSD 13.3 because only hard-core users have the skills and patience to follow THE PROCESS.

I know how to make an isolated virtual environment, install the package, make a fork, create a test and make a PR. But I don't know whether I care enough about a random project to actually do it.
I'm not sure if you actually read their previous financial reports, but their expenses were somewhere around $50,000-60,000, that doesn't indicate an inflated dev budget.

If you add up server costs, the cheapest possible accounting and legal services, and any other miscellaneous business costs, it doesn't really leave much of a budget for development.
As is typical for this type of psychology research, they did the experiment by asking a bunch of psychology undergrads to role play as liars or truth tellers after performing specific tasks, not by testing it on people found to be lying in the real world (which would obviously be quite difficult). This means that without further research, it's not clear whether it actually applies to other groups of people or scenarios.

For example, in this experiment, it seems like they specifically gave the people selected as liars an "outline" of the task that they didn't do to base their cover story on. It seems like this could also just show that trying to use something made up out of whole cloth is a simply a very bad strategy for lying compared to using details you have actually experienced (for example, if they had the test subjects perform BOTH tasks and had them lie about only the second task but use the details they remember from the first task for the second task, would this lie detection technique really have worked?)

This isn't to say that this type of experiment is bad, since it would be very hard to test this type of lie detection technique otherwise, but it is probably premature to report on it based on one experiment until it has been replicated in other experiments.
Yup. It’s been online for 7 years.
writing offers relatively high information density in a low bandwidth medium. but video offers high information density in a high bandwidth medium. the challenge in both cases is coming up with something to say that requires a high information density. for those who do manage to find something to say that requires a high information density format, speaking will be more effective (newspapers/books were replaced with radio which was replaced with tv). https://x.com/kenwarner/status/1840060518461010225

the infrastructure of the internet has matured enough now that we don't have to talk to each other in ASCII characters any longer. being online increasingly will mean using your voice and face (or suitable synthetic alternatives) to talk to the rest of humanity. not like TikTok though with its algorithmically driven mental corruption. and not like YouTube with its copyright oriented business model. More like early days twitter. Just everyday people talking to each other. But video. And realtime.
That one is a bit complex. Recycling things like paper, metal and glass works very well, in particular if they are sorted at the source. Most plastics can’t be recycled cost effective, which a lot of plastics producers have work very hard to hide.
I was also talking about Russian soldiers. You can exclude conscripts because at the moment the Russian regime seems to want to avoid civilian unrest.

> And as far as I know, defending mother russia from NATO aggression is a major motivator, as well as money is.

This is very confusing, and a lot of Russians are also confused by this by the way: what NATO aggression are you talking about?

> just that the world is not as black and white as fantasy often is

The Nazis crafted a narrative to start WW2 at a time when information didn't have the same freedom. This narrative seem to have heavily inspired the Russian regime: "ethnic russians are under threat in Ukraine!" instead of "ethnic Germans are under threat in Poland".

So the whole casus beli does seem to be a dark fantasy, and people are aware of this, to the point of completely dismissing that reality.

That's why I don't understand your point, nor do I see the logic of it.
Since I can’t reply to the dead child, the concept that you need training to interpret opinions sounds like a way to force people to believe your opinion without actually convincing them. It’s an extension of the “people are stupid, they need to be told what to do” from some years back that a certain party tried to push.
The thing stopping people from moving on from today's theories is there isn't a better one available to move onto.
They are probably both bad in excess, since that’s how calories work.
> Chinese people are increasingly forgetting how to write characters by hand.

For those who can’t read Chinese here, I’ll just note that this is basically the equivalent of forgetting how to spell certain words in English. For example, I can read just fine, but there are still words I’m not good at spelling.

I’m just noting this so that this problem doesn’t seem totally exotic or specific to Chinese(/Japanese).
I fail to see the logic in your comment. Just another case of Goodhart's law.

Sync everything to GPS. Record a harmonic of the carrier on the same tape, or just record the carrier itself on a parallel track. Have the SDR use this reference tone to undo any tape speed fluctuation artifacts. You can bring the deviation from DC so low that your comment no longer has any relevance to tape machines and just becomes a pedantic comment that mathematically perfect DC doesn't exist in physical reality.
Keep that in mind when you read or hear news about anything.

Yes it is about a lack of political will. US companies have been illegal in the EU for a decade now (Schrems II), but the enforcement of this is hardly anywhere to be seen.

It's the same kind of political denial as with being "concerned" about climate change, but still trading with China (even worse when this allows for fake self-congratulations about decreasing greenhouse gas emissions, when it mostly comes from most of the industry having been exported).
I just tried this on nixpkgs (~5GB when cloned straight from Github).

The first option mentioned in the post (--window 250) reduced the size to 1.7GB. The new --path-walk option from the Microsoft git fork was less effective, resulting in 1.9GB total size.

Both of these are less than half of the initial size. Would be great if there was a way to get Github to run these, and even greater if people started hosting stuff in a way that gives them control over this ...

This is not true for the strong force, but you wont get nonsense either if you zoom out far enough (coarse graining, right).

[So “perturbation theory works for SM”, but saying gravity is “non-renormalizable” gives the impression that Manuel Bronstein didnt already anticipate this before he was purged.]

mtw have a mnemonic “space tells matter how to move, matter tells space how to curve”. you arent allowed take short cut as in em “charges tell charges how to move”. Indeed (already true in SR) the fields themselves have mass, so short cuts blow up your face..

Otoh, if you try to take the proper path (integral) you run into the issue of nobody knowing how. Roughly, you need the intrinsic curvature for the integral but you need the integral for the intrinsic curvature..
