It was carried forward from days before checksums were a thing for the main data files. Enabling them on existing clusters was not added until PG 14 (in core - there was a utility prior that that could do it, but not much before). So before this there was no real way to enable them on existing clusters short of using logical replication (which as a ton of caveats and issues).

Even today, enabling as in the blog is not officially supported as far as I know (but it does work - I have done it in the past across tens of thousands of DB clusters) and is far from simple.

>We reached the point of rat habituation but didn’t start training. Our rats (Todd, Kojima, Gabe) aged out before full testing. The setup works, but behavioral validation is pending.

Ah man, what a pity. That VR rig is awesome, but it doesn't really seem to me they are planning to continue these experiments, or do they?

I highly recommend finding a cloud chamber (various science museums have them) to visualize just how much radiation is flying around.

Part of my work touches high power switches. I am going to do a bad job relating this story, but one of the power engineers was talking about how electric train switches in EU (Switzerland?) were having triggering issues. These were big MW scale IGBTs, not something you want to false trigger. Anyway, they eventually traced the problem to cosmic rays, and just turned the entire package vertical so the die was end-on to space (the mountains around were shielding the horizontal direction), and the problem went away.

Ok it's not just me that gets to the end of a page and it's like the page didn't exist.

On the other hand the times I use the search function on the ereader most are when I stumble across a continuity error. It would be interesting if a story-reading AI can be used to detect those. Not that I want there to be less human editing in books, if anything we seem to need more.

> It is not fair to me as a merchant

You absolutely can sell your product as a merchant! Best buy doesnt force you to pay them a fee, if you are selling electronics. You are perfectly within your right to ship the electronics to the merchant yourself and best buy doesnt take a dime!

The same is not true for Apple. For Apple, a customer can want to make a direct agreement with an app store developer, without the involvement of Apple in any way, on the phone that they completely own, and Apple wasn't allowing this to happen.

It would be like if it was illegal to setup competing stores that are located next to best buy that dont involve best buy in any way. That would be absurd.

It is even a bit more scrambled such as this part: hcihw selcihev selcihev ot ot ot ot erauqs strap. Looking at the original site, that text is in various nested structures with the paragraphs having that kind of text. They have multiple bits of it being an article block with a .is-paywalled governing various behaviors such as showing ads. The scrambled text is in paragraphs within the separate article portions. Presumably they have a script that will decode it for those to login though I do not understand why they even provide the text? Why not just return it after login? Maybe it is total trash text and just there to pad it out like a lorum ipso. Kind of interesting.

> where allocating using malloc(3) in one DLL then freeing it with free(3) in another being a crash.

This can still happen all the time on UNIX systems. glibc's malloc implementation is a fine general purpose allocator, but there's plenty of times where you want to bring in tcmalloc, jemalloc, etc. Of course, you hope that various libraries will resolve to your implementation of choice when the linker wires everything up, but they can opt not to just as easily.

> They deserve some fee

Not if the only way to get to the store was through that road. In that case, there are public access laws and it is literally illegal for people who "own" a road to charge people money, if there is an easement.

Thats probably a simplification, but they are called "easement by necessity." rights. So even in your example of the roadway, thats also wrong. They get zero dollars.

Can you look at any arbitrary program and tell if it halts without running it indefinitely? If so, you should explain how and collect your Nobel. Telling everybody whether the Collatz conjecture is correct is a good warm up. If not, you can’t solve the halting program either. What does that have to do with consciousness though?

Having read “I Am a Strange Loop” I do not believe Hofstadter indicates that the existence of Gödel’s theorem precludes consciousness being realizable on a Turing machine. Rather if I recall correctly he points out that as a possible argument and then attempts to refute it.

On the other hand Penrose is a prominent believer that human’s ability to understand Gödel’s theorem indicates consciousness can’t be realized on a Turing machine but there’s far from universal agreement on that point.

The article isn’t focused on Tesla’s market share, it’s focused on the mix of standard and premium product offerings they’ve rolled out lately and the effect that has had on absolute unit sales (and margins).

As it is they still can’t sell as many cars as they used to, which stands in contrast to Elon’s pay package.

Given that, the title seems accurate to me.

But you can compare generated power, right?

> In the 12 months to June 2025, wind and solar (2,073 TWh) generated more electricity than all other clean sources (nuclear, hydro and bioenergy) combined (1,936 TWh). Just four years ago, wind and solar generated half as much electricity as other clean sources combined.

> RE: NPM, you have a right to a preference of course. I certainly don't miss the times 20 years ago when pulling in a library into a C++ project was a two-week project in itself. make and CMake work perfect right up until they don't and the last 2% cost you 98% of the time. Strategically speaking, using make/CMake is simply unjustified risk. But this is of course always written off as "skill issue!" which I gave up arguing against because the arguers apparently have never hit the dark corners. I have. I am better with Just and Cargo. And Elixir's mix / hex.

I've lost countless hours having to get the rube goldberg machine of npm, jest, typescript, ts-jest and other things to work together. In contrast when I was learning OpenGL/Vulkan and general 3d programming, I decided to bite the bullet and just do C++ from the start as that was what all the books/examples were in. I had been told by countless people how hard it all was and how terrible the build systems were. I don't agree, I think the JS ecosystem is far worse than make and CMake. Now I am already an experienced programmer that already knew C# and Java, maybe that helped as they have many of the same concepts as C++.

Now I did buy and read a book on CMake and I did read the C++ 11 book by Bjarne Stroustrup (I found it second hand on ebay I think).

> What you like as a language (or syntax) and what you roll your eyes at are obviously not technological or merit-based arguments.

They aren't. What I am trying to convey is that it feels like a lot of things are done because it is the new shiny thing and it is good for resume/CV padding.

> "Weird" I can't quite place as an argument either.

The return keyword is optional IIRC in some circumstances. I think that is weird. I think I stopped there because I just wasn't enjoying learning it and there are zero jobs in my area of it.

> Use what you like. We all do the same.

The issue is that I think it (Rust) is going to worm it way everywhere and I will be forced to deal with it.

Current US law forces companies to negotiate with a union if it's employees vote for it. That seems like the opposite of a healthy market; it is a market in severe regulatory capture.

A healthy market would allow voluntary decisions by both parties. It would allow management to choose whether they want to negotiate with a collective broker, and it would allow workers to choose whether they want to find employment congruent with their preferences to either self negotiate or hire a third party.

I feel like these conversations really miss the mark: whether an LLM thinks or not is not a relevant question. It is a bit like asking “what color is an Xray?” or “what does the number 7 taste like?”

The reason I say this is because an LLM is not a complete self-contained thing if you want to compare it to a human being. It is a building block. Your brain thinks. Your prefrontal cortex however is not a complete system and if you somehow managed to extract it and wire it up to a serial terminal I suspect you’d be pretty disappointed in what it would be capable of on its own.

I want to be clear that I am not making an argument that once we hook up sensory inputs and motion outputs as well as motivations, fears, anxieties, desires, pain and pleasure centers, memory systems, sense of time, balance, fatigue, etc. to an LLM that we would get a thinking feeling conscious being. I suspect it would take something more sophisticated than an LLM. But my point is that even if an LLM was that building block, I don’t think the question of whether it is capable of thought is the right question.

I'll never say no to properly auditing our systems. So sure.

But I also recognize that few out there are pressing strong opposition to the idea of paying 3% for someone else to manage their financial transactions, or to host their own business. If I make a million dollars, paying 50k to Patreon or Kickstarter for hosting the service seems to make sense in my mind

It'd be interesting to see how this correlates across markets in different eras of history.

At the core, being a "founder" (as cringe as the cult around that word has become) is about accumulating capital. As technology advances it becomes more capital-intensive to create. You outcompete other businesses based on how advanced your technology is. Older people generally have more money even if for no other reason than they've had more time to accumulate it.

Thus, so long as you are still able to grasp the concepts related to the technology and can act upon it to accumulate more capital, you're at an advantage in the quest to start a successful business over younger people. Not an insurmountable advantage for the younger people to overcome, mind, but it's still an advantage.

Wow, the web version is neat in its simplicity! Thank you for the work on Solvespace. It's far and away my favorite MCAD program and always my first go-to when I need to crank out a quick fixture to test PCBs. It's really so pleasant and easy to work with as long as my geometry is relatively basic (which it almost always is given my limited scope of work with mechanical design). I'm sorry I don't have any comments on the relevant topic of the fonts, just was excited to see Solvespace mentioned.

> If you are so smug about this, answer me:

Please adhere to the HN guidelines and refrain from this kind of language. We can discuss this more civilly.

But I'll answer what I can, assuming your are genuine.

> 1: How man reactors were built in the 1970s and are nearing end-of-life?

10 reactors, 3 plants. (57 are currently operational)

I think this is a more American-centric comment than you realized... France had a bigger rollout in the 80's and a few from the 90's so there's another decade (*making this time key!*) before a slow decline. Also remember that France is a lot smaller than America so needs less power.

Not to mention, France exports a lot of electricity[0]. I want you to look pretty closely at that graph again. It says they exported 81.8TW this year. What's France's nuclear capacity? 380TW[1]. France exports about 15% of its total energy, more than all its hydro (it's next biggest source). You may be interested to see where that electricity goes....[2]

France can lose those reactors and be fine, Europe is a different story...

> 2: How many reactors has Europe built since 2005?

4, In Russia. But France built 2 reactors in 2002.

> 3: What's the overrun time of reactors in Europe, compared to China?

I don't have an answer to this but

> the institutional knowledge to bring it back to this quality does not exist

I can tell you that both France and the US are the biggest supporters of international aid in China's rollout. So the institutional knowledge exists and still progressing, albeit slower than before.

Besides, I'm not sure this fear even makes sense. What, China could "start from scratch" but "France" (or anywhere else) couldn't? What would make China so unique that such things couldn't be replicated elsewhere? This is a fallacy in logic making the assumption that once skills atrophy that they can never be restored or restore more slowly. If anything we tend to see skills restore far quicker from atrophy than from scratch! So why paint a picture of "give up"? Isn't that just making a self-fulfilling prophecy?

Can't black holes explain Dark Energy? Supposedly there was an experiment showing Black Holes are growing faster than expected. If this is because they are tied to the expansion of the universe (univ. expands -> mass grows), and that tie goes both ways (mass grows -> universe expands), boom, dark energy. I also think that inside the black holes they have their own universes which are expanding (and that we're probably inside one too). If this expansion exerts a pressure on the event horizon which transfers out, it still lines up.

Mining asteroids makes no sense in the current economy with our current technology. But working towards engineering solutions which makes mining asteroids make sense makes sense (if that makes sense).

However, it is much easier to see us send robots to mine these asteroids, or send robots to the moon to build a giant telescope on the dark side (if that makes sense), then it is to see us build cities on the moon to build said telescope, and to mine those asteroids.

You see the difference here is that the end goal of mining asteroids are resources being sent to earth and exploited, while the goal of space settlements are the settlements them selves, that is some hypothetical space expansion is the goal, and that makes no sense, nobodies lives will improve from space expansion (except for the grifters’ during the grift).

Appreciate you chiming in! We evaluated almost all the FDWs and landed on clickhouse_fdw (built by Ildus) as the most mature option. However, it hadn’t been maintained since 2020. We used it as the base, and the goal is to take it to the next level.

Our main focus is comprehensive pushdown capabilities. It was very surprising to see how much the Postgres FDW framework has evolved over the years and the number and types of hooks it now provides for push down. This is why we decided to lean into FDW than build an extension bottoms up. But we may still do that within pg_clickhouse for a few features, wherever FDW framework becomes a restriction.

We’ve made notable progress over the last few months, including support for pushdown of custom aggregations and SEMI JOINs/basic subqueries. Fourteen of twenty-two TPCH queries are now fully pushdownable.

We’ll be doubling down to add pushdown support for much more complex queries, CTEs, window functions, and more. More on the future here - https://github.com/ClickHouse/pg_clickhouse?tab=readme-ov-fi... All with the goal of enabling users to build fast analytics from the Postgres layer itself but still using the power of ClickHouse!

Well, the second and the third sentence describe very precisely what Unifont is:

"This page contains the latest release of GNU Unifont, with glyphs for every printable code point in the Unicode Basic Multilingual Plane (BMP). The BMP occupies the first 65,536 code points of the Unicode space, denoted as U+0000..U+FFFF."

This is suitable as a last resort font, which should display any character for which no match was found in the other available fonts.

This is normally preferable to a last resort font that just displays the number of a character not available in your preferred fonts.

Some may be confused into thinking this reply is a correction. I don't mean to appear to rebut.

We know that the FSF is aware of the problem. The trouble can only be if we expect more success from repeating the same tactics for the next forty years. I would blame no one for expecting the FSF to stay the course and to achieve similar effects. I would also not blame them for choosing a different path for themselves and recommending so to others.

I can understand why you're saying this and my response here will be more of a general reply to your direct reply's as it seems like a lot of them are missing the key element of WHY you can act this way in the current market. The big 'L' word, Leverage. In the current market you have all the leverage in the world as the employer to find a perfect fit employee due to the overall supply of workers and declining job market. When the market swings back the other way eventually however, the shoe will be on the other foot so to speak, and you wont have such privilege.

It's amazing how short our memories are for all the companies 10 years ago bending over backwards to give those employees anything and everything they wanted.

A lot of my statement here is very generalizing but at the end of the day market forces really do dictate a lot of this. I keep seeing article after article from hiring managers about how they're FLOODED with applications. You can't be 'polite' to all those people, as most people don't have the attention span for all that. There are definitely 2 sides to this coin it just seems that from the side of the people wanting to be hired they just have no empathy for those doing the hiring.

> You've been repeating this flawed comparison for years. It's getting really stale.

Well I've been repeating it because it's still true.

> The App Store is markedly unlike Wal-Mart or Kroger, in that a user cannot buy one thing from one store and another thing from the other.

You're just shifting around a definition of store to fit your argument. If you want to be consistent, it's more like you can't go in to Kroger and demand to buy products sold at Wal-Mart for Wal-Mart prices. You're in a different store.

> No it's not. The industry has no interest in overturning it, if there was commercial demand for an innovative third platform then we'd see one.

So the market is clearly saying "this works and we like it". It's just that the lawyers and accountants want to shift which giant corporation gets to keep more of whatever fee percentage.

> The crux of this issue is Apple becoming a services company and then denying competing services from competing on equal grounds. It cannot get any clearer than that.

Equality will never exist on these platforms, nor is equality necessarily something that's desired. Every company on earth that operates any sort of marketplace or store sets rules and boundaries that restrict competition. You're just mad about Apple/Google doing it because some algorithm decided it was an important issue for you. Do you know why that's true? Because you're sitting here arguing about Apple/Google doing it and not every other company doing it.

Even worse is that these changes that you champion have resulted in no price reductions, no "innovation", and have degraded features that I personally like and enjoy.

Yes because companies are famous for being highly law-abiding under every circumstance and every major instance of corporate fraud has been identified and properly punished at a criminal basis.

C'mon man, the US is a country where wage theft is 3 times higher than all other formst of theft combined. Informal blacklists are as simple as keeping a notebook in writing and letting people know through hidden WhatsApp channels.

The rule is vacated by an injunction.

> And? Id software developers are free to work non-gaming software jobs. A big part of the reason why game dev jobs offer less renumeration is because people are passionate about games and are willing to take a pay cut to work in the industry.

I have no idea why you think that a job being desirable and in high demand means that the people who effectively perform the job are somehow less deserving of workers' rights. The entire point behind having workers' rights is that basic job affordances and rights a non-negotiable because we do not allow certain forms undignified work.
