This was a regular sping night in a nation of 80 million people in the middle of Europe. Which means that for a lot of the rest of Europe it was also a quite night.

> It sounds cute, but essentially it is pessimistic and anti-technology.

No. It's realistic. Every time you show problems with intermittent generation by renewables, the answer is "sometime in unknown future we will surely build enough, and enough grid storage to boot".

Cost overruns are not unique to nuclear. Especially considering how underinvested nuclera has been for the past 20-30 people who keep spreading FUD.

When there's political will, there are results. Fuqing Nuclear Power Plant in China: 6.1 GW nameplate capacity. Built over 14 years at 1 reactor per 6 years. Operational. Estimated cost 16 bln USD.

I shudder to think about the future where we depend on whether or not the wind will blow at night.

Sure you can. That's what the current system of adjuncts is like.

The problem is that you lose the people who are the most competent. Those who know what they are doing, have valuable skills, etc.
BallBlazer/Blaster was an unreleased LucasFilms game, if I remember correctly. It was leaked and so wildly pirated that they didn’t bother releasing it.
There's an awful lot of students that held no job during college, and instead relied 100% on student loans to buy Taco Bell, pay rent, and put gas in the car.

The huge numbers you see tossed around almost always include living expenses. "$120k for a state school!" sort of thing.

The failure in reporting is those living expenses would have been incurred regardless if the person attended university or not.

As a society, I think we need to encourage people to work at least part time, if not full time during university - and take a slower path toward their degree. The result will be more experienced, mature graduates that have had time to evaluate their future.

That authoritarian countries are the main deployers and providers of nuclear is no surprise. The central government decides and there is no opposition. In most democratic countries nuclear is not competitive in the market anymore. For a country like Russia it's much easier to sell nuclear cheap into the market: they want to make European countries dependent on their energy delivery. Western countries have much higher technology standards and with market prices they are not competitive.
I like the php-fpm design of having a persistent server to run code rather than starting a process for every request.

I would like the convenience of replacing one file somewhere and have the file be picked up by the server, similar to PHP.

I would also like to separate release and deploy and do an atomic load of the server.

I think there are Clojure projects to preload the JVM.
Like any database, Datomic often needs to perform queries by reading data from its indexes. In fact, in Datomic, all data is stored in indexes - there aren't rows with indexes pointing to the rows, just indexes.

Datomic uses any of a number of stores, typically something like DynamoDB, to persist this index data.

When performing a query, Datomic peers read directly from the store (or from a cache) and read an entire block of index data as a single unit - each such block effectively contains many entity/attribute/value/transaction Datoms sorted by entity, attribute, or value, depending on which index is being scanned.

In other words, when reading all the attributes for entity X, Datomic will read from storage the block containing X, but also must inadvertently read other data that precedes or follows X.

The partitioning business is to ensure that related entities are stored close to each other; literally, a block of bits within the 64 bit entity id is set to the partition value. This ensures that the Datoms for related entities are stored close to each other, which in turn, ensures that the query can be satisfied using fewer of these index blocks, read from cache or storage, than if the entire entity id was arbitrary. Essentially, if entity X and entity Y are related, they can share a partition, and most likely will be stored together in a single index block.

This co-location of data can make a big difference in very large Datomic databases.
It'd be nice if Microsoft read this list and adjusted their software, like perhaps File Explorer, to be able to read and write this data. Or at least delete it.
What is the PHP equivalent of writing your front end and back end in the same language so you can share libraries and data and not have to switch gears between two different languages each time you look up or down the stack?

There is a HUGE advantage to using the same language in the browser and on the server, and PHP isn't ever going to displace JavaScript in the browser. So JavaScript it is. That ship sailed a LONG time ago.
Have you played a modern game? they have amazing levels of detail in the tiniest places. One game I play, Gran Turismo 7, claims that a single car model start to finish takes months to model for a single modeler. Some of the details in those cars that you can see in VR you can absolutely not see in-game normally, such as the door lock controls or the key-hole for the driver's door being exactly like on the real car, even for something so rare as a McLaren F1 longtail. There is so much waste of time and space dedicated to this stuff, but I love it personally!
Correct, but transport, steel manufacturing, etc. are also required for solar, wind, hydro, and whatnot. The real question you're asking is, "what is the net carbon emissions of nuclear power?".

And the answer is that it's lower than most renewables: https://www.world-nuclear.org/information-library/energy-and...
I'm relatively positive about nuclear power: https://news.ycombinator.com/item?id=35659464

Thing is, the best time to build it was the 60s. Now? There's a few cases where I think it's still the best option — ignoring politics, it would be great for shipping, and I'd be really happy if that somehow becomes a standard outside the military — but for most cases, it's just the most expensive solution to greenhouse gases, or joint-worst if you use LiIon as the storage solution.

And if you do want to ignore the political dimension, for example but not limited to the way that Israel will bomb any Iranian reactor just in case the latter might be weaponised, then to compare like-for-like you have to ask the same about a global HVDC grid — my fantasy-football solution, in that it's technically possible but still extremely unlikely.

> You will run out of land at some point

Ah, no. Not at present power use per person. Even England, which is not at all well-placed for solar, has enough land to be (electrically) powered by solar alone. Remember, civil infrastructure — buildings, rail lines, car parks, etc. — already has a huge footprint and PV can fit on almost any roof and between almost any gap.

(Also the wind can be offshore, apparently that's great for people who don't like the look of them on hilltops, less so for radar).
Well "place an index.php file in a folder to deploy" is a lot of server (maybe Apache / PHP) running to support that.

Node typically IS the server. So, you could install express and have a simple web server listening on a port and serving up html or json in about 5 lines of code. Unlike PHP Node is not, in itself, a templating language. So if you want to render HTML pages you'd also need to install something like EJS, but generally node servers are just serving up JSON API, and your frontend would be some frontend framework (React, angular, vue). Although all of that is trending back the other way with NextJS the old is new again and server-side rendering is the hotness again.

Another option is to use a framework like NestJS. With that you do

# install the nest cli (only needed for starting a new project)
npm i -g @nestjs/cli

# scaffolds a new project
nest new project-name

cd project-name

# node server is now running on port 3000
npm start

For easy deploy. That was kinda Heroku's thing. You just "git push" a node project and it magically knows how to deploy it, but Heroku got bought by Sales Force and murdered from my understanding. There are a lot of alternatives though. AWS, Azure, Google, CloudFlare, Digital Ocean, etc, etc all have similar offerings where you just push a node project to git and it deploys automagically.

Alternatively you can use AWS Lambda / Azure functions (or a dozen other "serverless" solutions) and you can just drop js files (functions) and they run on demand.

For a ProcessWire alternative there are a ton of options. A few I've seen are: Ghost, ButterCMS, Strapi

It's not just about the cost. The mix of nuclear and locally-available gas and hydroelectric makes for a self-sufficient energy strategy, and that has always been a major concern. Yes, Ontario is synchronized with the US grid but it could disconnect if necessary. Electricity is a valuable but not critical export economically.

As with France, a substantial influence on historic policy was to build surplus generation for economic security reasons. Could have just imported coal and oil. But Ontario does not have much coal or oil. Same with Quebec and hydroelectric.

Renewables provide the same sort of decentralized benefit, of course.
Really contrasts to PlayStation doesn’t it?
Like any programming language, encourage others to produce their own rather then just dumping "Use Symphony" "Use Flask" "Use Angler" "Use React".

This goes for all programming langs, the approach of "I know, lets use xFramework!" is flawed -- you end up with a generic X-lang website which caps your creativity because your locked in to using a framework based upon decisions of the developer. You add your stuff to it, dev updates the framework and you find out your stuff is broken because of some change. Frameworks restrict.

If people started to code their own like back in the day of PHPNuke, PHPCms, e107, PHPBB.. -- these languages wouldn't die. Not to add that the ecosystems of these frameworks are so fragile you end up with a convoluted mess where your stuck with the paradigm of the framework rather than your own design. This adds more further complication where your forced to abandon later on in the game or continue to be sucker punched because you want Z function, which won't be pushed in to the framework. You then create your own Z function but this adds overhead because any future update to the framework has potential of breaking your own function.

I'm an advocate to stop using frameworks. As a black smith does in making a hammer to smeld a tool to create an object. All takes time and effort, skills to develop. But when you do, the satisifaction is so worth it. Creating nothing is something; then from nothing creating something is an amazing feel. The wisdom, knowledge, hackery is far and beyond, you grow as a person. You end making something unique, something that no-one has ever made before. You have your own product.

Using a framework is skipping that step and using what someone else has created rather then your own.

Yes, controversial, you should be reinventing the wheel. Because if your not, your stuck with a pre-defined wheel where you are forced down a path of restrictions. Granted exceptions can be made if it's for corporate bandwagon but where's the individually of coding gone?
This is why we look at the actual amount of carbon released, not just a binary yes/no. I mean even if you had a magic power source that did not emit one single molecule of C02, a FUD spreader like you could use that exact same argument the first time a worker sparks a cigarette.

So tell me, how much C02 does mining uranium emit as compared to a coal station on a kg/Watt basis? six orders of magnitude less? seven?

"I am not against nuclear power" - this is litterally the calling card of a tactical hit, forum-wise. It very obviously means the opposite of what it says.

I generally look at how people perceive things like this as an IQ test. At the moment the HN visitors upvoting/downvoting things in this thread have failed my baseline IQ test.

How I wish all presumably well-intentioned but badly informed and ill-educated people who very often seem to have.. let's say, bad luck when thinking would just stop trying to spread their gospel via forums in this destructive way. Looking at you, vaguely-informed "friends of the planet".
The drop index.php into a folder is the only way I use PHP now.

Back when I was building applications in PHP it was all frameworks. package managers, op code caching, etc. But I no longer do PHP development but for my own personal websites I still use PHP but in that most minimal form.
This also highlights an extreme imbalance between ability to do great harm and bearing the brunt of said harm.
The best analogy for this I've seen is this: it's no secret that everybody poops. But that doesn't mean everyone likes having other people watch while they do it (privacy).
I think it's more disingenuous not to have quoted the rest that qualifies this statement compared to renewables:"...and able to meet growing U.S. calls for electrification and global needs for basic economic growth". The rest of the article goes into details about what you get for the amount of resources put into renewables vs nuclear and why nuclear outperforms once an investment is made.
I am not sure where you are coming from with that comment. Microsoft hasn't broken backwards compatibility on anything that I'm aware of in some time.

How to build a LLM search engine using a self-hosted LLM
Incidentally this code doesn't have any license attached to it. So if an LLM happened to produce this code and Oracle said "where did you get that?! did you illicitly include the Java code base as part of your training data?" the organization that got the data for the LLM training can say "no, we used Hacker News comments and this code happened to have been in there verbatim... sorry."

License successfully laundered!
While I think he's right, I wonder if that might still be a tradeoff worth making.
Or at least, a sane person could argue that it is. Competition between universities for rankings skews a lot of what happens in higher ed. The state of Texas could rationally think "we want to spend our tax dollars subsidizing the education of Texans, but we're not super interested in spending those dollars to fund the academic rat race."

The people who want to win that rat race will go somewhere else. UT will be greatly impacted but I don't think the overall scientific output of the USA will.
> Actually, a lot of people care.

I can see where a lot more people than we care to believe follow a philosophy in the same vain as that which was stated. Go ahead, do a survey and I bet you get a lot of "I care about climate change," but who's telling the truth and who's just trying not to look like a selfish a-hole? More people will lie, saying they care than will admit the truth and say they don't care.
Offline does not necessarily mean connected AT ALL, witch means not necessarily "local first" but "only local". Means on my iron, so under my control.

For the local first part, witch means "casually connected systems", the extra layer of complexity offer another layer of control and resilience: an autonomous car, capable of limited inertial navigation, with full local maps, routing capabilities etc can move even without GPS. Sure, it's more costly and complex than a connected-only car, but it's FAR safer to use.

Similarly an autonomous ship is far safer than a connected only one, for obvious reason.

Similarly in human terms local people with local power are FAR more resilient and effective than meat-based dysfunctional robots tied to some procedure. A VERY small simple example: I'm moved to France from Italy some years ago, now I decide to convert my perfectly valid Italian driving license in a local one. There is an automated (long) procedure. When I start it I've have had to give a scan of my Italian driving license witch happen to be expired and so got renewed BEFORE the procedure complete. In a resilient system I simply can upload the new one, sure this act trigger some extra actions, but extra actions who will happen anyway, only just after a bigger delay. Did you remember the Toyoda model vs the Ford one? Well, local first it's the same. At any scale.

True, it is mostly a capital cost for nuclear. That is probably why it makes more sense to get it paid by government.
I am pretty sure we very quickly in this discussion jumped from "what the state of the industry is" to "what the state of the industry ought to be", a very common debate failure point. I am just telling you what the case is. When you say you don't believe me, you don't present an argument that demolishes my case and says why I am wrong, you are just telling me that the industry is not doing what it could be doing. But what you originally asked me is "I mean, I'm interested to know. I peer review for a few journals and I never make a dime, so where does all the money go?"

I told you exactly where the money goes. You are entitled to an opinion that it's a bad way to spend the money, and that's fine. I happen to think that it's a suboptimal way to spend the money as well. But your question of "where does all the money go?" has been answered properly.
Maybe they just like the feature.

I mean you don't see all the Tesla owners giving up their cars. And a decent percentage of Tesla buyers were definitely Elon fanboys. One of the nice parts of Elon's recent adventures is that my friends with Tesla share far fewer Elon posts.

But some people bought and buy a Tesla because they just like the car and it has nothing to do with Musk. That's perfectly fine (and I think it's fine to be a fanboy too, who cares).
In Engineering (especially robotics and ML/AI), it’s definitely not the tenure that’s making people apply for assistant professor roles. Almost everyone I met did it only because they want the freedom to pick the research direction and work on challenging problems. A few genuinely like teaching, but that’s about it.
I honestly believe that most of the carbon calculations come from the pro-renewable folks to promote whatever pet project they’re on about. Nobody seriously considering building a nuclear power plant is going to care about some “externalities” amortized over its 50-75 year lifetime.
Yes, that's the problem. You can compress them for size at download time, and recompress them to a GPU-optimal format at the time of installation. You may even be able to do it at runtime with modern hardware, shortening loadtimes and sometimes even improving performance indirectly.
> Aerogel

From https://twitter.com/westurner/status/1600820322567041024 :

> Problem: #airogel made of CO² is an excellent insulator that's useful for many applications; but it needs structure, so foam+airogel but that requires smelly foam

> Possible solution: Cause structure to form in the airogel.

Backpack shoulder straps on e.g. Jansport backpacks have a geometric rubber mesh that's visible through a plastic window.

## Possible methods of causing structure to form in aerogel

- EM Hz: literally play EM waves (and possibly deliberately inverse convolutions) at the {#airogel,} production process

- Titratation

- Centrifugation

- "Volt grid": apply volts/amps/Hz patterns with a probe array

- Thermal/photonic bath 3d printing

- Pour a lattice-like lens as large as the aerogel sections and allow solar to cause it to slowly congeal to a more structural form in advantageous shapes

- Die-casting, pressure-injection molding
Guild Wars 2 and others solve this with progressive downloads. You may start playing after a fraction of the content is downloaded. There is effectively no downside: new players can't access most of the content anyhow. It also applies to updates: you can start playing after a big update with a partial download. The background process can be safely interrupted and resumed without glitches.
Yes, I detect the same sentiment (and it seems like a pretty natural one given the general audience here), but it also seems useful to see some data regarding the situation.
Which country's laws apply and what remedies you can get if they were violated is far more complicated than geolocation of data.

But very broadly speaking you would need to sue in an EU court to enforce EU law. And you could sue a US company in specific EU country's court if the company had more than some minimum level of connection to the that country. The country the data is hosted in isn't key, though it can be evidence of connection to that country.

> - one of the plant regularly leaks radioactive material

You need to quantify whenever talking about radiation, otherwise it's meaningless. Granite countertops also leak radiation, same as bananas.

Also, coal powered plants leak radiation every time they burn coal...because coal is radioactive too. They also release mercury, which is why we can't eat too much tuna fish.
Yup, basically converting random IO to sequential IO
The way this is being reported seems quite misleading to me.

"US warship collides with tugboat" seems to imply that the warship was at fault, when in reality my understanding is that it was completely unmanned and certainly not under power.

If someone tied their pickup to a dead tree in an attempt to uproot it, causing it to fall onto the truck and crush it, you wouldn't expect that headline to be "Tree collides with truck".

This is the fault of the shipyard, or of the tugboat crew.
No. It isn't absurd actually. Fans and employees are different groups of people with different obligations.
