There are a lot of answers here that suggest the colors have something to do with it. I think that is true, but no one has suggested what I think it is overall: the Gestalt Principles[0] in action.

The Gestalt Principles are from cognitive psychology, the part of psychology that deals, in part, with how we sense (eyes) and perceive (brain / mind) visual stimuli. Those principles are used a lot in interaction design, UX design, human-computer interaction, etc.

The specific Gestalt principle at work here is likely the "Figure / Ground" principle, also known as "background-foreground". Our brains are somewhat pre-wired to see things as either being in front or back of other things. There are some optical illusions that mess with our perception of foreground, e.g. Rubin's Vase[1].

The picture in question has the buildings in black, indicating they're silhouettes because the light source isn't hitting the walls directly. The blue of the background suggests some light coming from the night sky, illuminating things from the back. The brightly colored signs would provide their own light in the real-world context, and they have a high luminance value[2], i.e. high perceived value of lightness, as if giving off their own light.

To sum it up, it looks 3d because our brains have evolved in a three-dimensional world and have built-in functionality that helps us "fill in the blanks" in situations with incomplete information.

Do we think these will come down in price in the next few years? I $500 want one, but not $3000.
Yeah. I really wish cargo had a "create a build environment" mode. It would make integrating rust into other systems a lot easier.

IKEA and food court is where I cycled between when I was unemployed and just needed to get out of the house. Both excellent options. Breakfast is very cheap at IKEA too, and can be high protein.

Also when you have kids, taking them to Smaland at IKEA nets you 1-2 hours of free childcare while you work... or just relax.

jq is a DSL that is IMHO pretty hard to learn and remember. I kept trying to use it for years. I would find using a JS library much easier.

GitHub got a license from the US government to avoid sanctions to allow devs from Iran to interact with their platform.

Obviously no license is available or GitHub is not applying for it for devs in Russia.

There have also been the intentional blackouts of a sort, if I recall correctly, but those were to mitigate fire risk, not because of capacity, and aren't particularly related to electricity generation.
Wow. This is surprisingly good

AITA for spamming "rewrite it in rust" on Python-based Hacker News submissions?

NTA - Have you considered posting a guide to improving the Python ecosystem on HN? There are a lot of people who would be interested. There are so many Python projects out there that do amazing things. You just have to find them.

YTA.
If you want to learn more about language design, statically typed languages are actually a very good place to start. They make it much easier to determine what went wrong when things go wrong - and they tend to have better support for teaching people new concepts through formalized documentation and examples than dynamically typed languages where the only thing stopping you from writing an incredibly broken program is your own understanding of how what you're doing interacts with other parts of the system.

NTA. I'm a Haskell programmer. I once had to do some emergency backend scripting in Python for a project, and it was a miserable experience. I don't think I've ever written any Python code that I'd call "clean" since. I've heard the same complaints about Haskell, so I'm not sure if it's just the language or if it's common practice to write horrible code that's hard to read and maintain.

If you want to avoid this in the future, I would suggest either:

1) Not doing any back-end work at all, or
2) Writing the code in a language that supports prototyping, like Python, then translating the code to Rust once it's complete.

It's literally the first thing it says:

"1 In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.

3 And God said, “Let there be light,” and there was light. 4 God saw that the light was good, and he separated the light from the darkness. 5 God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day."

Earth, then light.

Then, later (after land, vegetation, the sky, etc), stars:

"14 And God said, “Let there be lights in the vault of the sky to separate the day from the night..."

> “If California is to have any hope of getting to 100% renewable energy on an August day in the future ... it will take 100 GW more energy produced by solar. Halting the progress of rooftop solar makes that goal impossible"

I'm also confused by the scales here. How are they praising the use of 15,000 MW (15GW) and 8,000 MW (8 GW) in one sentence, in an article about 97% of California's energy being used, and saying they need 100 GW in the next sentence and being sad they can't put it on rooftops. In an article showing a photo of a solar cell field in a vast, desolate, arid region of central valley.

It’s a joke. There’s not actually CRT in the math books. None of their voter base is actually going to open up a math book and realize that though.

This is actually a pretty simple one… most textbooks are made in Texas, somewhat controlled by republicans. They’re just banning anything they’re not getting a cut of the profits from & bringing in/giving their friends new textbook contracts.
Ask HN: Has YouTube been defaulting every video to 360p for you?
I pay for YouTube Premium, so it's been quite frustrating to always have to increase the resolution of every single video for the past few months. Bandwidth is most certainly not an issue as I have gigabit and can stream 8K no problem once I select that. It also seems (based on a bit of searching) that no one really cares or has noticed. Is this happening to anyone else?

Probably because one of those two facts:

1. The blue light is physically behind the others wavelength;

2. The blue is (much) more intense than other wavelengths.

Some background.

The LCD panel is a RGB filter in front of a white light.

White light is usually* made with a blue diode with some phosphor on top. The phosphor converts some (but not much) of the blue light into the rest of visible spectrum. Most of emitted light is the original blue from the diode.

Fun fact: The sun is also mostly blue. And there are white lights that are pretty much only blue, but we perceive as white (usually sold for vegetative growth of plants).

* In the past we used fluorescent tube. Quantum dot film are becoming common now (they have been used for a while, but are mainstream now because Rec. 2020). There are white diodes, but I haven't heard about them being used as backlight -- their CRI are pretty terrible, and they are expensive.
I suppose you could call them weapons of environmental destruction.

That 3.5 is almost without exception crime-related. Your odds of being a victim of extreme violence even if you weren't involved in what started it are effectively zero. Miyazaki prefecture probably experiences this same phenomenon. If even that is too much for you to risk, there's a city a couple of hours away with a population of 100k and a murder rate of 0.00. We haven't even mentioned the Japanese tendency to only prosecute slam dunk cases.

The major point is that although Tokyo might be "safer" on paper, the risk profile of letting your kid walk around Tokyo vs. letting your kid walk around the city I mentioned is pretty much the same in practice, and this goes for thousands of American cities. There are millions of Americans who could let their kids walk around their community and not have to worry about them being murdered or seriously assaulted.
Even still the crime rates in the US are extremely low.
Does anyone know an adblock rule to filter out HN articles telling me to buy an on-prem server to replace AWS? Seriously though, why are valueless bait articles like this so popular here? Is it collective satire that I'm missing? Is "you don't need AWS" a trendy counterculture thing? I could swear I've clicked through to equivalent articles at least five times from HN.
I already addressed this in the very comment you were replying to, certificate pinning is very easy to defeat with public tools.
In California August requires a lot more electricity due to AC than April. Seasonal demand differences can be huge, and why a lot of maintenance for nuclear reactors etc take place in the spring and fall.
> I'm sure you believe in a lot of things for which you have no personal proof.

I believe the only accurate and objective measure of truth is the scientific process. In the absence of running the tests myself, I would examine the process taken and make a trust-based assessment about the practitioners. Not ideal, I agree.

It seems likely that your statement is true, I can't think of any such belief right now.

> The information in Genesis gives information about several things that agree with known science ... there is no reason to suddenly doubt it's accuracy.

The internet is full of both truth and lies. Just because there is some truth, does not mean there are NOT also some lies / mistakes. The same is true of all works.

Just because some part of Genesis (or Tolkien's the Hobbit) matches reality (for instance, eating delicious apples)... does not mean the whole thing is accurate truth.

> Let's say I claim I'm a sentient being. You dispute that claim. On who should the burden of proof fall?

This is some deep ethics. Initially I would look to prove that you could effect your environment somehow. God clearly cannot, based on experiments relating to Prayer.

One means would be a Turing test?

Generally these are very deep discussions relating to sentience, the effects of that. I'd say that discussing that here would be a distraction from the proof thing.
Common Lisp implementations allowed you to change your program's code while debugging decades ago. Microsoft added bare minimum of similar functionality like fifteen years ago or so, if I remember correctly. I'm not even sure they've caught up on class redefinition and instance upgrade at runtime yet, which has been supported in CL since the 1980s.
If you know A and B, and you know C, then you know the diff from A to C.

If you’re in your 30s and retired from tech I’ll assume you’re likely some combination of bright, hardworking, and lucky.

Until then you’re a dilettante with big hopes and dreams. Nothing wrong with that and it’s quite fun.

Really great stuff Sam. I enjoyed that. Glad you're doing okay!

I don't think taking the SSRIs would be working against your peculiar tendencies, but that's just my opinion. Best of luck to you!
nintendo games have much higher replay value than the others you mentioned. they are mostly off line. they have different mechanics beyond graphics. people will buy them on multiple consoles happily. they are not rotting, these are active revenue streams.

nintendo isn’t afraid of mods, they would rather just sell you mario maker and create an experience.

quake and cod are mostly online, and there’s no community anymore. there’s over 30 cod games, no scarcity on the experience since they’re so similar. the one mostly offline game series you mentioned, halo, is closed source and still sold today. it is far less likely quake 3 is going to be bought and played today vs mario64. those games are not active revenue streams and don’t have a good path to become one again
CloudFront and Lambda, combined with S3 and a database (DynamoDB, RDS, Aurora Serverless), are quite powerful. You can do pretty much 90%-95% of web apps on these services.

Also API Gateway, if you need.

47yr old with 12yr old twins. Live in a million dollar neighborhood in Capitol Hill Seattle. Kids go to private school about a mile south of home. When the school year started, they wanted to walk to and from school alone.

We had to stop this in the last month and accompany them on the walks. My daughter saw multiple fentanyl od's on the street, my son asked me what that guy he saw was doing with the torch under the aluminum foil.

I grew up in the 80s in NYC and took the subway from Queens to Manhattan for HS (Stuyvesant). Plenty of homeless but mostly alcoholics, occasional mentally ill. The havoc from meth, fentanyl, heroin is too much for us to let our kids stay as independent as we want.
all these years later, and I still encounter systems that refuse to accept anything but a com/net/org/gov/edu email address. I have one ending in .fyi and .life and it's a no-go with a few places. Toyota, Paramount, and Experian come to mind.

What were their prices 10 years ago and what are they now?

I bet AWS loses even to inflation. Which means: in real terms - monetarily speaking - their prices went down.
> A quick search says in 2018 CA's electrical generation capacity was 80GW (which I assume has only gone up). So this 97% is a bit misleading, no? It doesn't represent 97% of total CA electricity usage... it's less than 30%?

Their full installed generation capacity is 80GW, but there's huge variability in actual load. As I write this, current load is around 21GW, on a range of between 18.7GW and 27GW over the day. It gets into the 40's in the summer.

https://www.caiso.com/TodaysOutlook/Pages/default.aspx

There's a significant need for reserve capacity to deal with this load variability, as well as plant failures, etc.
Once in high school I was at a friends house in a subdivision that didn't even have sidewalks. We wanted to go out for a walk but the dad gave us a warning that the neighbors would probably call the police because people don't ever walk in this neighborhood.
Hydropower actually has strong carbon-related undesirable environmental consequences, but probably not to such an extent in California as it does in Africa and South America. You'd have to find dam-specific data to verify that for Californian dams, though. It's not like with coal where burning 1 kg releases 3.6 kg of CO₂ no matter where you burn it. Emissions of a dam per kWh produced depend at the very least on its surface area, depth, water temperature, biomass inflow etc., all of which are dam-specific.
There was a talk that's been shared on here from Ben Horowitz where he explicitly pitches the 90-day window as a way to screw employees. That's probably where the perception comes from:

> The second way to handle it - no companies do this, which is why I actually really like this post that he wrote - is you can say up front, " Look you are guaranteed to get your salary but for your stock to be meaningful, these are the things that have to happened. You have to have vested. Two, you have to stay until we get to an exit. Untile the company makes it. You've got other money." Finally, the company actually has to be worth something. Because 10 percent of nothing is nothing. The reason we set the policy this way is we really value people who stay. So don't join this company if you are going to join another one in 18 months because you're going to get screwed. Our policy guarantees you're going to get screwed.

I reckon efficient swimming is too complex a process for spontaneous innervation to be responsible.

A fresh dead and pithed fish might flop, and might even flop several times in a row but that's about as far as it goes.

E.g. Just a change in temperature can make an efficiently swimming fish's red muscles’ duty cycles so maladaptive they are doing negative work, swimming requires really specific firing patterns.

Also consider — chances are they were moving an anesthetised fish into the experimental apparatus without realising it overdosed, in which case innervation would have been negligible.
> whether that actually makes sense financially or much more importantly in terms of the product roadmap.

If design docs don't at least mention the cost - and your business cares about cost - then you should probably have a chat with the engineering dept.

At a prior FAANG job we included basic cost analysis in our decisions. You don't always need the cheaper option if it doesn't make sense, but you should probably know the traffic that shiny new toy will receive and the cost associated with it. (eg. soln A needs 25% more compute, and the internal price is X vs soln B needs 10% more compute, but will increase storage costs for caching at X per gb for ~Y gb).

I recall a case where a coworker (Senior SDE in Silicon Valley, so easily 25k a month salary) spent a month reducing our $500 SQS bill to $350 because our director wanted to see teams making smart financial optimizations. Meanwhile, our EC2 bill was $50k a month. Not everything is smart financially to focus on fixing. What is the compSci quote on premature optimization?

Given how much competition there is in "the scene" for clout alone, there is no need to dismiss any criticism with "but its free". consumers/end users/spectators can absolutely complain and don't have to put up with anything and the production value increases.
