Theoretically x86 could be more efficient in terms of instruction caches and memory bandwidth, but it doesn't seem like this would be very substantial in most use cases. I'm not aware of many hot path instruction streams that are so complex that caches and interconnects are getting saturated.

Moving instructions to the decoder is way more expensive than actually decoding them. The factor is insane once you get to DRAM. But, it doesn't seem all that relevant in practice.

> Then, after 2-3 decades of doublings, you may be able to deliver $/Wh in the ballpark of where solar & storage is today.

I highly doubt that will be the case. Even if solar and wind do not get better costwise (which is likely not true) the cost of maintaining and decommissioning SMRs is likely only to go up. This based on every other nuclear power plant to date, I have seen zero good arguments on why SMRs would be an exception to that rule.

Even if you distrust your insulin supplier, there's good reasons to think that the insulin will be effective. The company will lose customers and sales if they put out a product that harms their customers and also that would likely put them at risk of litigation. However, if the supplier is taken over by some kind of asset stripping owner, then they might not care about future performance of the company.

The research wasn't entirely hidden as they did not have a monopoly on it.

In the 1980s, as a child, I remember learning at school about the greenhouse effect, or whatever we called it then. It was not difficult to understand, and neither was the 'nuclear umbrella' that we also had to contend with.

In the mid 1990s I was working in TV weather. We self-censored ourselves regarding global warming, or whatever we called it then. None of us were paid by big oil.

The euphemisms for 'climate change' tell their own story, it seems we need to downgrade the wording for the inevitable catastrophe every decade or so, I think we are on 'climate emergency' now.

As a result of what I learned in school, I genuinely adopted a low-carbon lifestyle which was quite hard to do when everyone was going the other way. If you step inside a car (when you have chosen to not own one) then you are deemed a hypocrite. If you don't eat those cows that create so much methane then you will be called a hypocrite for owning a leather belt. If you read a book then you will be called a hypocrite since trees had to be pulped. Be green and those stuck in the past will get all passive aggressive on you even if you aren't preaching to others.

When all is done we could collectively blame the oil companies for obfuscating the evidence of climate change. Similarly, when all is done with the current genocides going on, we can blame the politicians or the media for not letting us know the truth. Yet we are all a few clicks away from seeing how our alleged enemies 'report our crimes'. Yet, consciously or unconsciously, we censor ourselves.

>I also use them for brain-dumping. I find it hard to keep a journal, because I find it boring, but when you’re pretending to be writing to someone, it’s easier. If you have friends, that’s much better, but some topics are too personal and a friend may not be available at 4 AM. I mostly ignore its responses, because it’s for me to unload, not to listen to a machine spew slop. I suggest you do the same, because we’re anthropomorphization machines and I’d rather not experience AI psychosis. It’s better if you don’t give it a chance to convince you it’s real. I could use a system prompt so it doesn’t follow up with dumb questions (or “YoU’Re AbSoLuTeLy CoRrEcT”s), but I never bothered as I already don’t read it.

This is really great. I've managed to convert a few people to talk over Signal and while I am backing up my chats to my home server (I see you will be offering something like this in the future), this wasn't really an option for the people I converted over to Signal, so they were constantly afraid that they might lose the pictures or the chats if something happened to their phone.

I know, you can download media and save it through something else, but most people just opt-in whatever is default. I think my only suggestion would be to make it real clear or even maybe have some sort of counter that says something like "39 images are no longer backed up" or "8374 media items are NOT being backed up, 507 are in backup, 29 will be removed tomorrow". This could be directly on the backup page, I'm not currently running the beta build as I installed the apk, but if it's already on there, scratch the feedback!

Thank you again for all your hard work on this, it really is appreciated (financially too!)

Nuclear power plants struggle with economics already at highest possible capacity factors (running 90% of the time).

If they get undercut by renewables most of the time, there is simply no way they can stay competitive.

Nuclear peaker plants are not ever gonna be a thing, because that makes no sense economically: High capex is the last thing you want for that usecase, and it implies that the economics for your plant have to stay decent for the next 30 years. Meanwhile batteries, solar and wind are still getting cheaper every year right now. This is the worst bet you could ever make as an investor.

> nuclear may be a very sensible choice since a single nuclear plant can replace a whole lot of natural gas peakers.

This argument does not help nuclear power if the equivalent number of gas plants is still cheaper than a single nuclear reactor (and built much faster).

The problem is not with the ads but all the bad things that come along with it. Collecting unnecessary personal data, targetting, disregard for others privacy and list goes on.

These small bloggers/websites are letting the huge ad corporations take up the butcher job and cry when people use adblock.

Google provides a way to turn off ad personalization and when i turn it off you know what i see. Scam/adult/gambling ads and these small websites/bloggers are ok with showing scams to earn 0.01cents. then where they broke the social contract.

Google/meta with all the policing of billion youtube/fb videos/posts dont have same policing for ads quality. Thats where they broke the social contract.

Yes they need to make money, one alternative, I am ok with companies using my compute to run crypto mining( or scientific worlloadw ) when i use their website instead of ads. Small companies should look out of box for money rather than employing a butcher to make money.

This really isn’t fair. It is not simply hope and pray: it is a clearly stated/enforced deterrent that anyone who violates the policy will be terminated. You lose your income and seriously harm your future career prospects. This is more or less the same policy that governments hold to bad actors (crime happens but perpetrators will be punished). I get that it is best to avoid the possibility of such incidents but it is not always practical and a strong punishment mechanism is a reasonable policy in these cases.

> And I can't even call any tests because I can't extend a non existant class, there's no objects in here!.

I'm gonna preach for the church of "away with unit tests": so what? You don't want to test code. Code is not what the user care about.

You want to test behavior. And for this you don't need to extend classes. You should not have to rewrite any code from your application. Like you say: write tests at the seam. Automate user inputs and checking outputs.

A good test suite should not need to be rewritten during refactoring. It should even allow you to change language or replace for an off-the-shelf solution you did not write. If a unit test suite does not allow that, unit tests are an impediment. And I don't care about the "test pyramid", like the IRL ones, it is just a relic; from an age when launching all your tests in parallel was unfathomable.

I was fascinated on my recent trip to the UK to learn how much of their infrastructure they'd privatized semi-recently. Trains, hm, well it kinda works in Japan so maybe not so bad, but, water and SEWAGE??? In what universe does it make sense to have one of the most critical infrastructure systems, the backbone of health for a city, participate in a marketplace? Insanity. Not to mention the fact that at the end of the day only a government could possibly have the ability and authority and budget to run new lines or the motivation to do maintenance. What's next, pay per poop?

Also great video regarding this topic: "You Need to Be Bored. Here's Why." https://www.youtube.com/watch?v=orQKfIXMiA8

I now regularly force myself to "actively" do nothing for 15 minutes and just think.

All the things I put into my brain as "todo, please remember" at some point in time are coming back during these 15 minutes.

I get quite a lot of clarity with this exercise. As soon I pick up my phone afterwards and start browsing the clarity evaporates which feels bad. So wasting time on my phone becomes less and less appealing to me.

Lets see where this leads me. I so far wasted quite a bit of time with my phone.

Alas, Planets.nu has no source code available. That's OK if you just want to play, but I really always wanted to make some changes, and to self-host (like you kinda could in the original vga planets)

The UI and server are relatively simple though, so it should be a fun exercise to vibe-code a clone based on phost and openplanets.

A lot of people coming to Silksong having played Hollow Knight seems to be saying this, but also seem to have forgotten that pretty much exactly the same things were said about Hollow Knight when it first came out over eight years ago.

Almost like the collective memory of Hollow Knight's difficulty has dulled over time as people have, over the eight years, dare I say it, git good...

Are there things that are measurably more difficult? Perhaps. Common enemies can now do two masks worth of damage which before was relegated to boss specials, so environments feel more dangerous. This has always been a significant part of the early game, as an extra mask in Hollow Knight was significant enough to keep you safer from regular enemies, but in Silksong once you get hold of an extra mask you go from being able to be killed in three hits to...being able to be killed in three hits.

So I think there are things that make it feel tougher. At the same time though, all the same things were said before about the difficulty, about not knowing where to go (Silksong gives even fewer clues I'd say), but people persisted through areas, learnt boss patterns, and eventually just learnt the game up until P5.

And in a few years the collective memory of Silksong's early game difficulty will have gone as people adapted to it.

Case in point, Thames Water has been trying to build a reservoir in Oxfordshire since 2006[1], but has only met resistance by the local planning authority and environmental campaigners (the two often working in concert when it comes to NIMBYism due to various statutory obligations placed on local authorities.)

A few months ago the government reclassified the project as Nationally Significant Infrastructure Project to allow Thames Water to to take the proposal out of the hands of the local authority, potentially allowing the project to go ahead. [2]

If it goes ahead as planned it will be the second largest reservoir in the UK.

People aren't rational/perfect and Signal wants to keep them feeling safe? ¯\_(ツ)_/¯

(and IMHO there are edge case scenario where the additional friction in exporting messages provides some protection. Particularly when your threat model involves imperfect actors)

edit: here's an example. Let's say I use 4 week disappearing message with everyone I chat with. That's imperfect of course, but let's say right now only about 5% of the people I chat with are proactively backing up/screenshotting my disappearing messages and the rest let messages expire. If Signal rolled out an "export all messages to plaintext" feature, then suddenly that 5% might become 50%. And now a lot more of my messages which used to disappear, are being preserved.

If everyone I chat with is a perfect 'threat actor' that always backups up every message they ever receive, then there's no difference at all. But most people aren't, so practically there's a big difference because now exporting to plaintext (and bypassing time restrictions) is trivial for the masses.

> It’s not 45% of revenue expensive.

Youtubes profit margin isn't that high so it is pretty close to that, it took a long time for it to get profitable even with Google ads, unlike the digital stores that serves customers for basically nothing compared to how much revenue they bring in.

Twitch also takes around that much from streamers and they still aren't profitable since it costs more to serve the streams than they make.

BuildBarn's nfsv4 server looks great!

I'm not too sure about NFSv4 for ZeroFS specifically, the benefits don't seem _that_ obvious to me, especially compared to something like 9P, where server-side locking in the ".L" version is native anyway. Especially considering that most ZeroFS users are mounting the fs on the same box as the server is running and so local locks are working.

MacOS is a bit of a blind spot for 9P though, and a client there would be great.

I'm inclined to agree that privatisation is bad for long term planning, but the history of the Abingdon Reservoir proposal seems to be counter evidence:

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

Looks like Thames Water (a private company) proposed the development nearly 20 years ago, but it was turned down by the Environment Agency, a government body.

> Plans for a £1bn reservoir in Oxfordshire to supply more than eight million people over the next 25 years have been rejected by the government.

> Thames Water wants to build a site on four square miles of land near Abingdon to help ensure future demand is met.

> The bid went to a public inquiry but the secretary of state said there was "no immediate need" for such a site.

Reagan, Thatcher, all the same, and their ideology kept alive by neoliberals (basically every politician that isn't an out and out socialist or snidely toeing fascism) and the Chicago school of economics.

Find me a national leader that believing in the flourishing of the country (and all the people in it) and I'll find you an entire political apparatus in opposition to that in favor of the flourishing of Capital.

It's real risk; Under oath before the French Senate, Microsoft France’s Head of Corporate, External & Legal Affairs Antoine Carniaux, said he cannot guarantee European data is safe from U.S. government access, even when stored in Europe. U.S. laws like the Patriot Act and Cloud Act require American tech firms to comply with U.S. authorities, regardless of data location. That means, especially with a current US administration acting against EU interests, that a US based AI solution is not safe.

Agree, though an intensive one (8500km in 6 weeks) that is just subjective experience, which is why I caveated it mentioning that it was our own family personal experience.

I lived in a mountainous area of Italy (very narrow roads, full of ups and downs) so I am a fairly confident driver (probably why I was not too stressed driving in Italy) and drove in countries like India and Iran in the past (so very familiar and happy with slow, but very crowded and unpredictable traffic).

To clarify, the anxiety we had on Autobahn and Swiss' highways was not a reflection on the quality of the roads, and more a reflection on the driving 'style' combined with the speed that those roads allow. The style was quite aggressive, very fast in every lane, loads of overtakes (car constantly zig-zagging), people coming from the back _FAST_ and staying there, people switching lanes immediately after signalling rather than giving some time for people to notice. Overall, that combination made for a very stressful experience which we have agreed (as family) not to repeat in the future.

As a reminder, the British water treatment system was privatised in the 1960s and has been a huge joke ever since. When they were still in the European Union, common environmental and health regulations prevented the worst from happening.

But as an example, one of the first actions taken after Brexit was to stop monitoring and treating sewage discharges into the English Channel.

It's the gaming/HPC focus, sure you can achieve some stunning benchmark numbers with nice vectorized straightforward code.

In the real world we have our computers running JIT'ed JS, Java or similar code taking up our cpu time, tons of small branches (mostly taken the same way and easily remembered by the branch predictor) and scattering reads/writes all over memory.

Transistors not spent on larger branch prediction caches or L1 caches are badly spent, doesn't matter if the CPU can issue a few less instructions per clock to ace an benchmark if it's waiting for branch mispredictions or cache misses most of the time.

There's no coincidence that the Apple teams iirc are partly the same people that built Pentium-M (that begun the Core era by delivering very good perf on mobile chips when P4 was supposed to be the flagship).

The amount of tanning isn't really an indicator, because it depends on the genetics how much melanin is in the skin to begin with and how much is produced as reaction to damage. I think the most important thing to keep in mind is not trying to get tanned intentionally, like the generations before us. IIRC, in about 70% of melanoma cancers you have a good chance of catching it early and be done with it. Once it metastasizes melanoma got a very bad prognosis. So, as adult, it's also important to frequently screen for it. Other skin cancers are usually not existentially threatening, but can fuck you up aesthetically, e.g. removal sacrificing chunks of your nose.

Personally, I use the UV index charts and avoid extremes, midday sun completely. I put on 50 SPF to my face and neck every time I leave the house. It's just routine. In winter I may skip it, because good sun screen is fucking expensive. Not so much about skin cancer, but rather skin aging. The face is always exposed. I am trying to get a little intentional sun exposure in spring after dark winter, slowly preparing my skin for summer and improving mood. However, I tan easily. If I had the skin type I, I would avoid the sun much more.

Did you notice how many people these days look younger? Even in their 30s? I think that's no smoking, intentional nutrition, exercise and sun screen (from childhood on).

That model already exists, it is called the internet. There you pay for hosting and advertisements and everything, and you also get all the revenue.

It isn't very popular since the internet doesn't advertise your content for you, youtube do that so its much easier for content creators to get big on youtube. Also it is free to upload on youtube, so small creators start there, small creators later grow to big creators and stay on youtube.

We talked about this a few weeks ago so it can't be the first time you're hearing about this :) [1] You hadn't heard about it before because it really only affected API customers running services including calls that required output of 2.5k+ (rough estimate) tokens in a single message. Which is pretty much just the small subset of AI founders/developers that are in the long-form content space. And then out of those, the ones using Sonnet 3.5 at the time for these tasks, which is an even smaller number. Back then it wasn't as favoured yet as it is now, especially for content. It's also expensive for high-output tasks, so only relevant to high-margin services, mostly B2B. Most of us in that small group aren't posting online about it - we urgently work to work around it, as we did back then. Still, as I showed you, some others did post about it as well.

The only explanations were either internal system prompt changes, or updating the actual model. Since the only sharply different evals were those expecting 2.5k+ token outputs with all short ones remaining the same, and the consistency of the change was effectively 100%, it's unlikely to have been a stealth model update, though not impossible.
