In reality electricity in China will NOT "be provided fully by renewables".

The country's current fleet stands at 56 reactors. China expects to build 6 to 8 new nuclear power plants each year for the foreseeable future and is projected to pass the U.S. in nuclear-generated electricity by 2030. In total, China intends to build a total of 150 new nuclear reactors between 2020 and 2035.

China has an impressive expansion of solar. That's a fact.

China is also expanding coal power stations (while closing older shitty coal stations) to provide base energy for its planned and ongoing expansion of both solar and nuclear.

Currently something of the order of 60% of the energy requirement of building solar (for local use and for global supply) in China comes directly from coal power.

I'm all for renewables, it's the sensible direction.

I'm also big on factual statements.
They are using the WebKit rendering engine, but there’s a lot more to a web browser than just its rendering engine. They aren’t just skins.
That is the opposite of what we are seeing though. Which largely comes down to "hydro works really well with melting snow" and some level of "it's windy up here". But for solar, you probably have a point
What's the bad assumption in that question? Is the ticket going to come with a cure for aging too?

> Why is it okay for a person to view your content, memorize it, and use it as a base for new content while it's not okay for an AI? at the end of the day it is the same thing.

Because it is not really AI. We can have this comparison when it actually can think. Until then this 'training' is just big data processing and that is not what person can do by reading/watching.

i say this is not correct.

What is "intrinsic" value? I argue that if people want it, then it has intrinsic value.
I share your befuddlement. Eclipse is good and overall better than even paid proprietary IntelliJ. I think there is a lot of bandwagon jumping, especially with newish devs.
Sorry for the slow response, don't check my threads as much as I could.

This was back when I was in the aid business, so the gig involved a lot of going around and talking to all sorts of people: local community organisations, farmers, processing plants, schools, local government reps.

A lot of it's the sort of vibes you pick up doing this sort of thing for a while, and having other contexts to base a comparison on. I felt a clear chain running down from the top to bottom. I live in another post-Soviet place, it's a lot more chaotic: still one big man at the top, but the vibe is more of a graph than a tree.

Good things and bad things, well that's almost philosophical. It's one of the poorest countries in the region, one couldn't help but think it might be doing better if there was more space for independent action.

On the plus side, the architecture in Dushanbe (a comparatively new city) was gorgeous. If you've just got one company doing the architecture and build for everything, you get a nice harmony to the place.
People are not only getting their news from 12 year olds on TikTok; they are learning everything from the same people. Social media is a disaster but many people are still ignoring or dismissing it; a large amount of people have not been taught critical thinking and so they spoon up whatever someone with a face they find friendly says. I cannot understand how it is not 18+, all of it.

Anyone likes mechanical keyboard sounds?
Hello everyone!

I don't have different mechanical keyboards and these keyboard sounds are very addictive to hear. I love typing on my MacBook so one day I downloaded an app from GitHub that would make different sounds of the mechanical keyboards from your laptop's speaker when you type. well, I have low RAM (8 GB) on my Macbook and that app uses the Electron (the desktop framework which is popular for sucking up too much RAM) for the app it also had memory leak issues.

So one day my developer friend suggested me to join the app that he was building. his app shows the keys/shortcuts that the user presses with very good and cute-looking themes. he was building it for presentations, instructors, and YouTubers to enhance their tutoring experience. he also planned the cursor highlighter feature with different styles.

When I joined in I thought it would be great if we just tried to implement the mechanical keyboard sounds feature too! we did add it to the app. It works so well and our app is built using Flutter which doesn't take much RAM on desktop apps. so that problem was solved!

so now we have 10+ different keyboard sounds in the app with many cute/attractive themes for the showing keys/shortcuts and cursor highlighter too.

you can check out the app here it's available for the macOS and Windows: https://keystro.app

Spot on. I would just add that, exactly for the reasons you describe, going to a four year US university and then turning pro is becoming a lot more common. Off the top of my head I can name a half dozen guys in the top 100 who spent at least a few years playing D1 tennis.
Yep. Sometimes it's "known issues are avoidable issues", and other times it's "hey I wish we didn't spend xx% of our time avoiding (incl. spending time auditing syntax) or doing mitigations for the same limitations/issues over and over and over again".

The wheels do turn, just slowly.
Nah, C holds claim to some of it
It's a pilot plant. Its purpose is to develop, test, and demonstrate the technology. If successful then they can follow through with plans to build bigger plants that run at full capacity. They won't get the funding for the latter step without the former step first.

It's not only about the length of the method. Ternary operators may look simple enough, but they could lead to some subtle errors. For example, try to guess what's wrong with this code:

List<String> result = new ArrayList<>(input.size() + newItem == null ? 0 : 1);

From the testimonials it seems this is used for tactical rather than strategic planning. Honestly, that would keep me up at night.

It's similar to problems which have been previously caused by a reliance on in cockpit weather data delivered by satellites. At worst it can be 15 minutes out of date and more than one eager light aircraft pilot has flown into the center of a storm cell which wasn't there 15 minutes ago - taking his family with him.

Its only turbulence but worst case scenario with turbulence is still pretty bad - injuries and even deaths are completely possible outcomes.
Magnific's recently released Relight feature is really cool, but it's a bit pricey for non-professional creators. So, I made an alternative:

redis's C code is incredible
In qft there are no singularities, everything are fields. Particles are just such fields, a singularity in qft would mean you have a Dirac delta shaped field, I don't think such a field exists in reality and I don't think many working physicists would believe in them either. The big reason they can't even come up with math for the black hole singularities is just because the theory doesn't support working with such Dirac shaped fields.

Edit: When they say electrons doesn't have a size, what they mean is that there is no limit to how small you can make an electron, not that it is always compressed into a point.
Well ok, in 10-15 years all fossil and nuclear electricity in China will be a drop in the bucket. They will probably be commissioning a terawatt per year of solar by then, or more.
It's hard to narrow it down, it's from compilation to pushing the Flutter to its limits. It's overwhelming, I think Flutter might have the highest number of questions on SO. I'm not sure if Google is moving fast enough with Flutter.

Agree it does them no service using that name. It’s miles worse than IntelliJ or VS. Even if it became much better in recent years (haven’t used it for over 10) its first 10 years have many of us so many scars we’ll not go near it, and we’ll think twice about using something with a similar name or origin.
I know a few who still swear by Eclipse but they are the kind that think the Linux desktop audio stack is great because it’s open source too.

It's curious that despite trains and rail networks being a perennial nerdy favorite, the simulation game selection feels somewhat limited.

For example is there any that simulate real-world signaling systems, such as ETCS or it's national peers? Or are the different systems truly so generic that you can just substitute them with generic signaling mechanisms?

Recently I've been playing Factorio and the trains are fun challenge there, but the tools to build/design/analyze rail networks feel very limited (at least in vanilla base game). So now I kinda have bit of an itch for better rail game but haven't found one yet. And from the looks of it I don't think Locomotion is it either

This article is a great example of a really frustrating thing people are doing, which is pretending that all this AI business started two years ago

I get it, GenAI became popular as a consumer-facing product and tech industry PR blitz in that year. But people in the tech world should know better. AI as massive industry-wide GPGPU workload took off in the 2010s, including widespread usage of smaller models like CNNs throughout both FAANG's stack and in scattered startups, as well as supermodels used as recommendation engines by everyone and their grandma. Arguably the entire business models of every irresponsibly large tech company ran on this shit. All the telemetry. Ad targeting. Social Media feeds. Hell, GPT-3 came out before 2020. It was a scandal in this world when OpenAI exclusively licensed it to Microsoft, who was already probably using it in search at that point. None of this was actually that long ago, this is way too soon to have cultural amnesia. I get that I'm in somewhat of a bubble as an AI researcher but surely tech publications should at least know these basic facts, right? Is this yet another reason to be annoyed at the 2010s lingo for calling all these pervasive neural networks "the algorithms"?

From the perspective of energy expenditure from AI workloads, the statement that it's a major driving force of the rising energy demands of datacenters is a perfectly reasonable conclusion given a graph where the TWH more than triples between 2012 and 2024. The article sometimes specifies "generative AI" (which did exist in 2012, but was in a way less interesting state for most people and businesses until 2022), but often just says "AI", which is a big umbrella term people have at least consistently been using for most neural networks for that entire span of time (and longer, and for lots of other things, and it's hopelessly overloaded to the point of being nonsensical sometimes, but regardless this is an incredibly uncontroversial usage). So someone at a data center with a graph that basically tracks the rise of GPGPU neural networks and shows a big jump in energy expenditure over that period attributing this to "AI" is very reasonable!
1) also resources that are practically infinite. You’re not going to run out of nuclear fuel.

2) No, but the sun will go extinct. Hence it is either that all things that are “practically infinite” are renewable, or they are not. Nuclear fuel is ultra recyclable - most of the “waste” we make in the USA is because (primarily) uranium is cheap and recycling is expensive.

3) just pointing out that nuclear is as renewable as anything else.

Nuclear is badass, but I think it’s probably not going to win over solar… combined with “clean” LNG, which the USA has massive reserves of, which we burn at an alarming rate, and whose load could be totally consumed by nuclear plants.

That won’t happen though. Largest reserves and we make a ton of money burning it and selling it? Nothing will change. We’ll add a ton of solar - and the ~20% addition of LNG peaker plants (from ~1000 to ~1200) will be seen as a “victory for solar” because there will be whole days California is “powered by the sun”. Just ignore all the peaker plants that turn on when we need them and pray for a battery miracle.

> Making fuel for those by taking CO2 out of the atmosphere is a double win.

It's just a single win because the CO2 is going right back into the atmosphere as the fuel is used (carbon neutral, not carbon negative). Still, a win is better than the loss that extracted fuels amount to.

I found this article about a young swimmer really interesting:

https://www.theguardian.com/lifeandstyle/article/2024/jun/02...

I know a family with a pre-teen son investing a huge amount of time in another individual sport. 4-5 hours every weeknight, putting pressure on schooling and on the family by limiting schedules and recreation. They all give a certain look when they talk about it, knowing that there is a cost to creating (potentially) an elite athlete. At least the kid himself doesn't look glass-eyed and lonely, but I do wonder how that life would compare in hindsight to regular family, time for socialising, regular holidays, etc. This is not really sport with NBA money at the end.
Unanticipated "roll for initiative."
It feels like the entire JavaScript world seems overly influenced by e-commerce, pushing all kinds of optimization, even including RSC and SSR. As a former SaaS builder, I deeply resonate with the author's point:

"I care way more about the speed at which I ship features, and all that complexity becomes a burden on my dev team."

This is exactly why I started building ZenStack(https://zenstack.dev) toolkit. The goal is to brings simplicity back to building SaaS applications, using whatever framework you like.
Makes me wonder what it would do if you throw a couple of 301/307/308 at it.
Yea, that's basically it on iOS, although there is a bunch ux, so it's not nothing

On android, browsers can ship their own engines, and they do. There is actually some freedom on android.
"Conversely, thermionic tubes for a hot environment could be built without heating filaments. If the ambient temperature is 500°..."

There's a lot of physics and engineering behind thermionic emission in a typical vacuum tube and the subject shouldn't be overlooked just because tubes are less commonplace than they once were.

Until the transistor became popular in the latter half of the 20th C. essentially all of electronics relied upon thermionic emission so much effort went into understanding it. Moreover, it's still very important in specialized areas such as in scientific instruments, high power transmitting tubes, TWTs (Traveling Wave Tubes), CRTs, etc.

Thermionic emission obeys Richardson's Law—after physicist Owen Richardson who received the Nobel Prize for his work in 1928, and its study is an essential part of thermodynamics: https://en.m.wikipedia.org/wiki/Thermionic_emission.

When I was learning about this stuff I had a little book titled Thermionic vacuum tubes and their applications by Sir Edward Appleton (who is more famous for his wartime research into radar). Still, for anyone who's interested in thermionic emission then this could be a useful reference.

I'd add that when it comes to practical methods of manufacturing thermionic cathodes, info on low work function oxide emitters etc. then there are references that are better or more practically orientated (but offhand I cannot remember the names of any).

None of this is a "big business". I think thirty years ago there was probably a perception that it could be a big business, it's potentially a license to print money, but sufficient incompetence got them here instead. Look at ISRG's volumes, that's the potential volume available in the Web PKI, but that's at $0, we know the resistance to even low prices is fierce.

If you asked people from the for-profit CAs about Let's Encrypt before it launched, the impression you'd get was that they're issuing a lot more certificates and this doesn't matter. Millions per day? Ha, we'd barely notice. That was all bluster, they were never doing that.

I think Apple probably had the best shot to turn this into free money. Apple's customers are very willing to pay more than something appears to cost on the basis that it's Apple so it's worth it. I think you'd struggle a lot more to undercut a $10 Apple PKI product with a free offering that's identical because Apple's customers are used to justifying why they spent more money on the same thing with the logo on it, and they are able to be completely irrational about it and it's OK - a brand rep would look unhinged if they violently attack people who point out that it's bullshit, loyal fans will get understanding or even praise.

I actually thought about 10-15 years ago that Apple was about to do this, but they didn't and once Let's Encrypt happens there's no room really. Apple does still make money off some places where they're sole issuer and get to charge arbitrarily for doing nothing, but not like they would if they'd seized the entire Web PKI.

Federer was 27 when he won his first French open. His first slam was Wimbledon which he won when he was 21. You are thinking of Nadal who won his first French open when he was 18. Also there have been players who won their first slam much later in their careers. Schiavone for example reached her first slam final and won it when she was almost 30.
Last I checked, the Flutter GitHub repo had more than 12k issues open, so I definitely agree that there's a lot of questions/issues.

But I take that as an indicator of popularity, not a serious problem with the project. If there were truly fundamental issues, there wouldn't be as many issues raised because noone would be using it :)
In the 90s, I played a computer game whose name I haven't been able to remember. You built railroad tracks and trains would pass through your town(?). I'm pretty sure it was played from a top-down view and the terrain was gray, but honestly the main thing I remember is how, on holidays like Halloween, all the assets automatically changed to suit.

I don't suppose this is familiar to anyone :)
This seems not entirely accurate. "malloc_usable_size" was only recommended for use for statistics before the change in man page: "Although the excess bytes can be overwritten by the application without ill effects, this is not good programming practice:" and "The main use of this function is for debugging and introspection". The new version makes it clearer. You can find the change here:
https://git.kernel.org/pub/scm/docs/man-pages/man-pages.git/...

Also no code is "actively broken" by a documentation change. If it happened to work before it still works today. Also I do not see how __builtin_dynamic_object_size is broken. It works as intended and can be used with conforming code just fine. It is simply not compatible with some questionable use of "malloc_usable_size".
Cynical me thinks it sounds like an attempt by Big Food to future-proof themselves against ingredients that may later be found to be an allergen. Have they considered that the plastic packaging they use might be shedding microplastics etc into the product. Er, loaf ?
