> The problem with nuclear energy is not the availability or the cost of the fuel but the capital cost of the reactor and the high level of financial and operational risk involved with the construction.

Yes, in US and western Europe it's been practically impossible to build new reactors since the 90's for capex and regulatory reasons (both are related). However, we used to be able to build reactors significantly cheaper and faster and I'd argue we're on the path to do it again later this decade. There's no technical reason we can't solve this problem: there's bipartisan support for nuclear, willing financial backers, and no demand shortage. We're going to see 100+ gigawatts of new nuclear in the western world in the next 20 years.

> Coding is formal

I just don’t see it like this; code is craft, and there are ten ways to solve any given problem. Reasonable people can select different tradeoffs, and taste is also a big factor.

Maybe if you are working in very low-level algorithmic, compiler, or protocol development it’s less ambiguous. But almost all software is written many layers above that.

I’m sure if you already sat down and thought through every detail, you might find LLMs slow you down vs typing. Many people use the process of writing, or the process of iterating with customers, to flesh out the ambiguous detail; in which case improving cycle time can improve your time to PMF.

Go on, 'Prove it'. Write a version that's faster.

You're trying to say that pushing a function call frame is faster than writing a single value to memory and incrementing an index, and when asked to prove it you made something that allocates and deallocates chunks of memory to a linked list where every access takes multiple pointer dereferences.

In California it's more than showing up (although I think none of the tests are particularly rigorous).

Minors must:

- Complete a 30 hour driver's education course and 6 hours of driver's training

- Pass a knowledge test with 80% or more questions answered correctly

- Apply for and receive an instruction permit

- Maintain the permit for 6+ months

- Drive with an 25+ year old adult supervising for at least 50 hours (including 10 night hours)

- Pass a behind-the-wheel test

Adults must:

- Pass a knowledge test with 80% or more questions answered correctly

- Apply for and receive an instruction permit

- Maintain the permit for 6+ months

- Drive with an adult supervising for at least 50 hours (including 10 night hours)

- Pass a behind-the-wheel test

Minors have additional restrictions on recently issued licenses.

If EVs in general rose 24% due to rushing to get in before the tax credit ends but Tesla—the largest seller—only saw a 7% bump, isn't that a failure? #2 GM had a 10+% bump. Ford had a 19%. Hyundai, Honda, Kia, and Toyota all rose 60+%. Volkswagen rose over 450%. Sure it's fine in a bubble, but they are doing worse than most other car makers.

I've migrated from Synology Photos. It's pretty seamless, since Immich now supports External Library. I use Docker Compose in Synology, so basically all I have to do is just mount existing Synology Photos folders to Immich. Works fine, no issue so far.

However, I'm back to Synology Photos. I'm using Immich iOS apps. The upload/syncing is noticeably a lot slower than Synology. Gave it a few months, but it's not getting any better. Moved back to Synology Photos for now.

I understand what you're saying, but at the same time floating point numbers can only represent a fixed amount of precision. You can't, for example, represent Pi with a floating point. Or 1/3. And certain operations with floating point numbers with lots of decimals will always result in some precision being lost.

They are deterministic, and they follow clear rules, but they can't represent every number with full precision. I think that's a pretty good analogy for LLMs - they can't always represent or manipulate ideas with the same precision that a human can.

As the original article points out, not all languages come out of the box with a sane/rationally designed dependency manager. I can think of only a handful in that category. The vast majority of languages fall short and rely on secondary community projects to prop up the dependency management for the language: maven, gradle, npm, pip/pypi, now uv, etc.

Language designers in general terms will fall into the "more knowledgeable than the average developer"category , but let's not pretend they're anything but mere mortals like the rest of us.

NGL Ive somehow lost the thread and can't tell if we're talking about language integrated dependency managers in the abstract (in the OP), or specifically speaking about golang, odin or something else. I don't know what the emo wars are specifically in reference to but I think we jumped the shark here.

Sure you can. For example, UK will jail you if you refuse to disclose a cryptographic key for something encrypted that the court wants to see, so long as the judge is convinced that you know it. I could easily see that extending to steganography: "there's no rational justification for you to have this file, and statistical analysis patterns show that it likely has a steganographic payload".

Haha, I’m the author of the post.

I planned to fix the performance issues before posting here (since I knew HN would be quick to point that out), but somebody posted it first. You’re absolutely right — it’s pretty slow right now and needs optimization.

And it’s not just the refraction/displacement map: plenty of other parts, like visualisations, aren’t optimized yet either.

Yeah, huge in Latin America in the sense that a lot (most?) business only have a number that they use with Whatsapp (you can't call or even text them). Is it the same in Europe? Since I am from Latin America I never know if people from other continents use Whatsapp as much as we do, and if when I ask them to use Whatsapp I am imposing a new app or it's what they regularly use.

I want to see a real explanation of the bungling that makes projects go 3x late and over budget and it is not "environmentalists" who might make it go 20% late.

I've looked long and hard and not found an explanation of the bungling fitting the facts better than that it's like a poker game: the vendor never believed in the sticker price, but the vendors figured that once there were chips in the pot the sunk cost fallacy would mean the buyers would never fold.

Thing is, they do, at least in the U.S.

https://en.wikipedia.org/wiki/Nukegate_scandal

I think NuScale was trying to be honest about costs but the buyer in Utah built a process in which they could control costs by folding early and they did. Europe, China, and other places have more engineering thinking and less financialization and they're more likely to "stay the course" but as an engineer I'm not sure this is right -- it might work for China but not for Europe.

On one hand I'm glad to see GE get the BWR, especially the work done on ESBWR, back into the game with the BWRX300, but the costs they are quoting are too freaky low and their talk about "design to cost" makes it seem like they just quote the cost number that they need to be competitive with the solar sticker price without storage which will lure in the public as opposed to being competitive to whatever the (unknown) solar + storage sticker price will turn out to be. (e.g. highly variable because it depends by "how frequent blackouts will your accept?")

There's lots of other options... I'm not sure I could recommend Synology these days as they've started to vendor lock to only their drives, etc.

You could get a NAS from TerraMaster and swap the OS for TruNAS Scale or Unraid. They're relatively reasonable for the hardware, you can also DIY the hardware but that brings in other issues. Got an F4-424 Pro for a backup NAS myself. Worth noting a few big drives will cost you more than the other hardware though. 12TB was the pricing sweet spot when I got mine.

This joke was funny a decade ago. EVs have been practical for ages now. See how well early model Teslas fared. Some people doing 1-2 million miles. 300k miles is not uncommon.

You don't need revolutionary batteries (similarly you don't need next generation nuclear plants, ordinary ones create so immense amount of wealth for generations). Batteries improved like 10-15% since early Teslas. Similarly motor/aero/electronics efficiency. Overall 30% gain in range. If right charge infrastructure it's perfectly enough for 99% of passenger cars.

> When the whole chip is idling at 1-2W, 0.1W of socket power is 10%.

But how are you losing 10% of power to the socket at idle? Having a socket might require traces to be slightly longer but the losses to that are proportional to overall power consumption, not very large, and both CPU sockets and the new CAMM memory standard are specifically designed to avoid that anyway (primarily for latency rather than power reasons because the power difference is so trivial).

> Some of Apple's integration almost certainly save power (e.g. putting storage controllers for the SSD on the SOC, having tightly integrated display controllers, etc).

This isn't really integration and it's very nearly the opposite: The primary advantage here in terms of hardware is that the SoC is being fabbed on 3nm and then the storage controller would be too, which would be the same advantage if you would make an independent storage controller on the same process.

Which is the problem with PCs again: The SSDs are too integrated. Instead of giving the OS raw access to the flash chips, they adhere a separate controller just to do error correction and block remapping, which could better be handled by the OS on the main CPU which is fabbed on a newer process or, in larger devices with a storage array, a RAID controller that performs the task for multiple drives at once.

And which would you rather have, a dual-core ARM thing integrated with your SSD, or the same silicon going to two more E-cores on the main CPU which can do the storage work when there is any but can also run general purpose code when there isn't?

This is expected. Tesla enjoyed a more than a decade long position as the leader. Even now it’s a strong pick because of the extensive charging network they built. No other company comes close, and this charging network will reap recurring revenue for them.

However the cars themselves are really shitty. I mean really bad for quality and do not offer any aesthetic value either, they appear very plain and generic at this point. I can see why people are picking other cars. Of course the whole nazi turn of their founder doesn’t help.

It's not even just the US, that just happens to be where most of these companies register their copyrights, and therefore, where the "infringement" occurs.

Many Western countries subscribe to some form of "contributory infringement" law, where someone can be fined tens of thousands per-work-infringed for simply developing or distributing a tool that can be used by someone else to infringe copyright. It's absurd.

I don't know why we're putting politics aside. I'm sure those political escapades didn't help in cratering their stock.

All companies are trying to cut on variety right now. Of course, a software service used daily won't be hit as hard as a mid-class car company. Heck, even the affordable car companies are charging mid tier prices these days. The results are clear if things don't change.

My grandfather was tenured, published voraciously up until he retired at 73, and was sorely disappointed when I chose not to follow in his footsteps and go into academia. Why? Primarily because I had to hear him gripe about how poorly the school administration treated him and his colleagues, culminating in him having to sue the university several times for the same reasons (and him winning every time in arbitration- he basically tripled his retirement savings).

I have a lot of respect for academics, but the culture around the administration of higher learning is putrid.

We only have a sense of time in the presence of inputs. Stick a human into a sensory deprivation tank for a few hours and then ask them how much time has passed afterwards. They wouldn't know unless they managed to maintain a running count throughout, but that's a trick an LLM can also do (so long as it knows generation speed).

The general notion of passage of time (i.e. time arrow) is the only thing that appears to be intrinsic, but it is also intrinsic for LLMs in a sense that there are "earlier" and "later" tokens in its input.

> The chopping up can happen the next cycle

It still causes issues.

> Since x86 instructions can be as small as one byte, in principle the throughput-per-cache-line can be higher on x86 than on RISC-V (e.g. a single 32-byte x86 cache line could have up to 32 instructions where the original RISC-V ISA might only have 8).

RISC-V has better code density. The handful of one byte instructions don't make up for other longer instructions.

> And in any case, there are RISC-V extensions that allow variable-length instructions now, so they have to deal with the problem too.

Now? Have to deal with the problem too?

It feels like you didn't read my previous post. I was explaining how it's much much simpler to decode length. And the variable length has been there since the original version.

Seems to be nfs v3 [0] - curious to test it out - the only userspace nfsv4 implementation I’m aware of is in buildbarn (golang) [1]. The example of their nfs v3 implementation disables locking. Still pretty cool to see all the ways the rust ecosystem is empowering stuff like this.

I’m kinda surprised someone hasn’t integrated the buildbarn nfs v4 stuff into docker/podman - the virtiofs stuff is pretty bad on osx and the buildbarn nfs 4.0 stuff is a big improvement over nfs v3.

Anyhow I digress. Can’t wait to take it for a spin.

> I think intelligence

That very phrasing belies the problem with the word: There is no consensus on what intelligence is, what a clear test for it would be or whether such a test could even exist. There are only people on the internet with personal theories and opinions.

So when people say AI is not intelligent, my next questions are whether rocks, trees, flies, dogs, dolphins, humans and “all humans” are intelligent. The person will answer yes/no immediately in a tone that makes it sound like what they’re saying must be obvious, and yet their answers frequently do not agree with each other. We do not have a consensus definition of intelligence that can be used to include some things and exclude others.

If you're in a group and someone is backing up the messages, it only affects your messages in that group. All of your other chats are still secure as long as you're not using the backup frature.

You (and Signal) can't control how the recipient handles your messages if you're not using disappearing. They could be copying and pasting your messages or taking screenshots. I don't see how the backup feature is any different.

Nope, tarriffs. I'll admit that the 175% tarrifs on Chinese vehicles was indeed a Biden decision.

To be precise, 100% on vehicles, 50% on solar cells, and 25% on Batteries.

You are always paying, either in time or money. Which you pick is based on your assessment of where resources of time and money are best spent forward looking. Some people do their own laundry. Some pay a laundromat to do their laundry. Why do some pay? Because those that pay have decided to trade money to buy some time back for another (higher value to them) activity. There is no right or wrong answer, only tradeoffs based on current ground truth and predictions.

Paying Datadog (or whomever you elect to manage observability) means you're not paying someone to or spending time focusing on said observability. That is time you are presumably spending on development velocity to accelerate revenue growth. Balance growth and optimization accordingly.

Because you’re one person with a job which isn’t security, and the world is full of legitimate warnings from companies telling you that you must do something by an arbitrary deadline?

They screwed up, but we have thousands of years of evidence that people make mistakes even when they really know better and the best way to prevent that is to remove places where a single person making a mistake causes a disaster.

On that note, how many of the organizations at risk do you think have contributed a single dollar or developer-hour supporting the projects they trust? Maybe that’s where we should start looking for changes.

I don't disagree, it's just that the advantage hasn't yet been shown to be big enough to justify dedicating die area in a mainstream chip. There's potential there, if I were designing an accelerator today I would look hard at posits and variations of blocked representations especially around four bits. A few years back I got to have coffee with John Gustafson which was pretty neat and got me more excited about the idea.

Nuclear proponents argue that renewables (solar, wind) are not base-load, and nuclear is. They are correct.

But the people building power generation are doing it on a for-profit basis. Since solar is cheaper to deploy, faster to deploy, simpler to maintain and so on, that's what for-profit people build.

In other words, on the one hand you have large generators, requiring years of planning & permitting, a decade of construction, endless court battles from the anti-nuclear folks, generating returns 15 years from now, competing with the exact opposite (cheap, quick to build, beloved by eco folks, easy to run and maintain, off the shelf parts etc).

From a capital point of view its a no brainer. Capital follows profit, and solar is very profitable.

Nuclear may be good policy. Base Load may be very desirable. But unless govt is putting up the capital it just won't get funded. (Nuclear plants are being built, like in China, but using govt capital, which sees a return in more than just cash terms.)

There are lots of strong arguments for Nuclear. But Nuclear proponents need to address the capital requirements above all. Until the capital problem is solved, every other argument is useless.

> Checking the existence of features and polyfilling is not that complicated.

Judging by what we see in the world, most developers don't agree with you. And neither do I. A handful of browsers, multiplied by many versions per browser in the wild (before evergreen browsers like Chrome became widespread, but even today with e.g. Safari, or enterprise users), multiplied by a sprawling API surface (dare I say it, a standard library) is not trivial. And that's not even considering browser bugs and regressions.

> very hypocritical of developers that won't blink

Not a great argument, as developers don't necessarily get to choose how to add analytics, and plenty of them try to push back against doing so.

Also, the cost of parsing and JIT'ing JS code is byte-for-byte different to the cost of decoding an image.

From what little I know of the NY art scene, by osmosis (by having an SO who previously was accomplished in it, and could mingle well at gallery openings and cocktail parties, infinitely better than I could ever learn to)...

I wonder whether the "rude, rude, rude" means that the market had come to depend on nouveau riche speculators (who'd typically have neither the intellectual and artistic background, nor old-money social graces/conventions).

If you didn't respect your customers, and didn't make them feel valued, then the ones who only cared about money or status games have other options.

Incredibly cool! It shows running Ubuntu and Postgres, and also supports full posix operations.

Questions:

- I see there is a diagram running multiple Postgres nodes backed by this store, very similar to horizontally distributed web-server. Doesn't Postgres use WAL replication? Or is it disabled and they are they running on same "views" of the filesystem?

- What does this mean for services that handle geo-distribution on app layer? e.g. CockroachDB?

Sorry if this sounds dumb.
