But you are putting focus on it, just doing it less efficiently (imo and what other people say as well). Why not use the same time and use it more efficiently.

"I will go to the gym, but will not even break sweat, will be fakingly training, just jumping from one machine to another, without plan, execution or dedication" - is the MO of a lot of people in a commercial gym. They are there, but they are definitely running away from hardness. Don't know how well this applies to you.

In life, you need to run to keep the same place. In order to advance, one has to sprint, to put effort. Purposefully slacking and easing often means that practically you are regressing, being left behind.

I understand if you were strong enough, put effort, got the results, and want to scale training down in order to maintain and to concentrate on other more important things. But:

1. You are not that strong. You can definitely build a better strength/muscle foundation that will last the rest of your life. The health retirement fund. It is the easiest to do now, while you are still young. You can do much better.

2. But even if you think that the current level is enough and are only interested in maintaining, the way you do it is clearly suboptimal. Both gaining and maintaining would be easier, faster and more efficient with highter weights and fewer reps. You can also save time because you can do fewer sets in order to get the same maintenance effect. Alternatively, you can keep the same sets/time, but actually progress (or do it faster) instead of staying at the same place. Same cost, bigger psyout. This is the result of doing the right things the right way, instead of giving up and doing something that feels nicer.

Cheers!

For all the insightful takes about everything under the Sun, Dan's cynicism and skewed view towards "Europe" are shown in this letter.

It's not that all his takes are wrong, it's the exaggeration, the doom and gloom and a somewhat dismissal or some unsolved personal issues he has with "Europeans".

The irony is not lost that Dan acts as smug and dismissal as he accuses Europeans to be.

Regarding the whole "Degrowth" thing: yes Europe has those and they found their gold in Governmental entities and they entertain the rich. But.. that's exactly what happens in the US too and Dan as knowledge as he is should know this was mostly an American academia export, he just needs to talk with some people in the very same colleges he regularly set foot into.

Also, he should take a hint when he says historically liberal societies have fared much better than autocratic ones even if those are very focused and appear to make progress very quickly. Having a few mega-bilionaires directing what the populace do or not do might not be a smart move as it sounds. We'll see when the AI musical chairs stops.

Btw, Europe has been dead and on the brink of destruction for a few centuries by now. And according to experts the EU is about to collapse 3 or 4 times a year - minimum.

Author here.

Thanks for the feedback everyone. I appreciate your posting it @woodenchair and @aurornis for pointing out the intent of the article.

The idea of the article is NOT to suggest you should shave 0.5ns off by choosing some dramatically different algorithm or that you really need to optimize the heck out of everything.

In fact, I think a lot of what the numbers show is that over thinking the optimizations often isn't worth it (e.g. caching len(coll) into a variable rather than calling it over and over is less useful that it might seem conceptually).

Just write clean Python code. So much of it is way faster than you might have thought.

My goal was only to create a reference to what various operations cost to have a mental model.

I find that people speaking very loudly into their wireless headsets wherever they are and whomever they are with is a bigger nuisance.

When you speak to someone in person, you'd adjust the volume of your voice to the room and the recipient without thinking about doing it.
The engineers who built the analogue phone system were aware of this effect, and made it so that you heard yourself in the handset's speaker. The engineers who designed the cell phone standards decided to ignore this so they could do more echo-cancellation.

It is not a big problem when people are speaking into a slate-shaped cell phone, but when people wear headphones that attenuates their own voice, they hear themselves less and speak extra loudly to compensate.

PWNO provided a patch but it was rejected for being too large[1]. A maintainer fixed it himself[2]. I don't know if PWNO used a LLM but it seems clear that the maintainer had a preferred specific style in mind so it was likely hand written (albeit inspired by the initial patch).

We are using Nix to do this. It’s only a few lines of code. We build a gcc 14 stdenv that uses an old glibc.

But I agree that this should just be a simple target SDK flag.

I think the issue is that the Linux community is generally hostile towards proprietary software and it’s less of an issue for FLOSS because they can always be compiled against the latest.

> teachers who, when faced with an autistic pupil, will play a game of sorts to see which parent has undiagnosed autism

Great, diagnosing people based on casual observations. Wasn’t friendly enough, not great eye contact, said something odd…must be autism.

Our tolerance for weirdos of all kinds seems to have gone both down and up at the same time. Why can’t they just be people who are a little unusual?

> Whatever the deal is, he's probably not wrong about autism.

I agree, but it’s worth pointing out that this is kind of his whole schtick: Most of the topics he posts about are probably objectively based and generally accurate. He uses this to build trust before slipping in the bananas claims about immigrants, race/IQ stuff, and other political topics, or when it comes time to sell followers on subscriptions to his GLP-1 guides (which do not contain any information you couldn’t find freely from numerous other sources)

Rationalists and "skeptics" aren't really capable of maintaining a robust club because a) it's hard to find healthy critical thinking in societies that are still addled in a swamp of tribalism from millennia ago, and b) not believing in fables is a weak social pretext. (Hey, let's get together for pints and not believe in $somegroup's ravings.)

The application of rational thought is an educational process. With all the inherent fragility of any educational process.

Housing in the US is labor constrained. When I talk to GCs, subs, etc., they'll say that materials a bit more expensive, and labor is a bit more expensive; but what the complain about — and this can be for hours, if I get one going — is the complete lack of labor in all trades. This isn't a new problem; the "old hands" (GCs in the 60s and 70s) noted the labor drop out even 30+ years ago. The only saving grace we had was a strong trade force incoming population (immigrants); but, we've cut that off.

It wouldn't surprise me if our industry is also labor constrained? I know my brother had a machine shop to make aftermarket titanium parts for (motor)bikes, some cars, etc. He had a policy of nonstop looking for new machinists, even if he was fully staffed, because a machinist could just wander off at any time. With only 4 employees, he could find himself at at 25–50% loss of ship time in just a few days, at any time. It's not even like the machinists were getting more money. They'd just leave, because the new shop was 5m closer than his.

Fixing the labor pool issue is a decades long issue. More money in that pool won't fix things. I don't even know what's going on. Maybe I can just blame modern financialization for the issue? That seems easy, if wrong.

But, for sure, the complete lack of social safety net for labor can't be helping. Maybe if we guaranteed child care, 100% round-the-year safe spaces (we could use the fantastically expensive schools which are empty 75% of the time?), 3-free-meals-per-child, and free education through an associates degree? None of those are particularly expensive, even at the national scale.

Yes.

>How far should sanctions go? Sanction enemy banks (layer 1)? Sanction citizens of neutral countries who do business with the enemy country (layer 2)? Sanction citizens of neutral countries who do business with other citizens who do business with the enemy country (layer 3)?

You're doing a great job of writing my policy! The sanctions should tigten every time noncombatants are killed.

It's bizarre to me that there is still so much effort spent on resisting IPv6 implementations, we were converting some industrial control networks to it almost 10 years ago and those organizations are basically defined by ancient equipment. Rather than byzantine v4 NAT coordination we mapped entire plants and substations to V6 addresses and put in 6to4 for the PLCs that were old enough to vote, so that multiple sites that all used the same 10.x.y.z blocks because of course they did could be routed together. Had V6 available from my house to pretty much anywhere I cared about in 2017.

Outside the purely electric vehicles (where I believe Tesla competes very well, where is BYD at with FSD?), is there a Chinese equivalent to:

- The upcoming EREV (mostly electric extended range hybrid) F-150 truck? This is expected to have ~700 mile range, and of course no charging hassles. It’s main advantage over the now defunct Lightning will be towing range.

- The Chevy Corvette Stingray? Say what you want, but the high end ICE sports cars have an appeal of their own…

I believe the USA still has an edge in some areas of the market.

> He still lives in the same home he bought when he was 28 years old.

What does “living” mean in this case? That can mean absolutely nothing. I travel a lot (and probably Buffet too), and tax authorities would have a headache with what should I pay and to whom if I reported it completely to them when and where I am. In the country where I officially live I’m maybe 20-30%. There is no other countries with more. The simple case of 50%+1 days is nowhere near. In Buffet case, it can be even less. 10 years ago I had a different pattern. I wasn’t at home but in the same country (in the case of the US, like a state) at random places like 80-90%. So does Buffet really live there, like properly?

If it's done systematically and has predictive power, there's nothing wrong with that.

How else do you propose we diagnose something that doesn't show up in MRIs and bloodwork?

Or we could just as well dismiss any mental issues entirely, and say "if we can't measure it, it doesn't exist".

Every time Bartosz posts come up, I drop everything to read it. The way he builds up the mental model from a simple photon bucket to a pinhole and finally to a lens system is just incredible.
I particularly loved the section on the Circle of Confusion. I've read dozens of explanations on depth of field, but being able to interactively drag the aperture slider and see exactly how the cone of light narrows and the blur reduces makes it click in a way that static text never could. This really should be the standard for digital textbooks.

I'd wonder about the performance impact of windows defender and the like.

I'd really wonder if one took a game that was on both xbox and linux. constructed a linux box to have basically as close to specs as on the xbox and then benchmarked the games against each othe, what would would see.

I'm not saying that linux is better than windows or that windows is better than linux, just that I think its very hard to make an apples to apples benchmark comparison and there are constant services on windows that run that one doesn't generally have running on a linux system that can cause problems.

Why does anyone need to be defensive about what someone has found for them?

For example, studies have shown that men who decide to isolate themselves to be "family men" die earlier at age 58.

It might not need to be a pub, but having a club house to do pretty much anything is enormously beneficial to the human brain to have positive social interaction.

We get to decide our own social interaction.

The world is not responsible to not triggering us.

+1. Point number 5 is probably the worst part of their post.

Beginners should focus on form, consistency, and linear progression of weight. If you can stand the boredom do the exact same program for a year. Probably 2-3 full body workouts that hit each body part twice.

For intermediate+, hitting a body part once a week is suboptimal for most. People who care about results and progression/growth should be progressing from 5 up to 20 hard sets per muscle per week across the span of a few years. (Compounds hit multiple, so it's not necessarily 20 hard times the number of muscles!) What's "hard"? in the 0-2 RIR range, ideally to failure.

For advanced, as i understand it, they need to focus on weekly periodization like hitting 3RIR, 2RIR, 1RIR, 0RIR (test new 1RM), Recovery week kind of cycles. Plus more that advanced coaches can teach.

You seem to misunderstand. I don’t reject socializing because of a few negative experiences, I just don’t get any significant positive feelings anymore from the majority of my social interactions, after many attempts, and especially when compared with interactions from long ago. It isn’t just other people, I have changed too. Even interactions that “go well” just don’t provide anything of value. What’s more, I don’t miss it. I much prefer what I have now.

I don’t travel alone, I travel with my partner who is a great companion.

In 2023 I built a similar community around parties in my (small) apartment. With a group of around 80 people in the end, usually about 30 shown up. It was great fun, but ultimately it did not build a community. It was great, but vast majority of the connections were fleeting.

Turns out partying is not something that really builds bonds.

Well the "solution" for that will be the GPU vendors focusing solely on B2B sales because it's more profitable, therefore keeping GPUs out of the hands of average consumers. There's leaks suggesting that nVidia will gradually hike the prices of their 5090 cards from $2000 to $5000 due to RAM price increases ( https://wccftech.com/geforce-rtx-5090-prices-to-soar-to-5000... ). At that point, why even bother with the R&D for newer consumer cards when you know that barely anyone will be able to afford them?

China has been performing debt swaps with local governments to clean up their balance sheets [1], so used as an example. Agree with all of your comment.

You were absolutely correct that it's a bad experience, and that probably a lot of people hated it and think less of your company for doing it. But since every site behaves this way it's not a deal-breaker for people anymore. People either find a way to get around it or just suffer with the crappiness of the modern web and your metrics just go brrrrr.

If you are already running a VPS, the SSH -J option is useful if you don't want to expose your SSH to your home public address.

You create an SSH reverse tunnel (-R option) from a server in your home network to your remote VPS. This gives you a localhost port on your VPS to your server SSH port. Something like:

ssh -NT -R 2222:localhost:22 vpsuser@yourvps.com

From your laptop, use your your VPS address and localhost port in the -J option. Something like:

ssh -J vpsuser@yourvps.com:2222 homeuser@yourhome.com

I only allow ssh key auth and only my laptop is trusted by my home server. The home server doesn't need to trust the VPS "jump server".

That's not what the parent commenter said. They said consumers don't care, not that they asked for the jacks to go away. You're misrepresenting.

But in terms of consumers not caring, yes:

https://www.androidauthority.com/ting-headphone-jack-survey-...

It's objectively not a popular feature or something the vast majority of consumers are looking for.

Most people prefer Bluetooth because you don't need to deal with annoying wires getting tangled, ripping your earbuds out, etc.

Again, it's not that the market asked for the jacks to go away, they just don't care. And when there's something that consumers don't care about, companies tend to remove it. The jack takes up volume. Not huge, but on phones every cubic millimeter counts. And it's one more thing that can break.

And if you really want a jack, there's a $9 adapter you can just keep attached to your headphones. So everyone wins.

It’s honestly amazing if you’re the right type of person for it (I know because I have a similar life to the author and I love it). The one important thing, as the author discovered and this article is about, is to make sure to keep up some amount of social life and not become a complete shut in as that genuinely becomes miserable after a while (at least it did for me until I started revitalizing my social life as well, though not in the way the author did).

All that is to say, please don’t feel pity for us haha. I asume the author, like me, genuinely enjoys this lifestyle.

Going further, you don't even need to count your reps or track how much weight you're lifting. Literally just do any exercise with any weight per muscle group to near failure for 2-5 sets. Rest the muscle groups you targeted the next 1-3 days, and be consistent every week. Bodyweight, free weights, machines, bands, kettlebells, etc. are all fine. That gets you 80-90% of the benefit with no stress.

Some of the best B2C customers are on FB — willing to spend, low expectations, low maintenance.

If you add IG to the mix, it’s even better.

Your typical HNer does not really fall into “ideal customer” profile for most B2C businesses. Our saving grace is our above average income profile. Other than that, on average we are tolerated rather than sought after (imho).

In another article, I read a US citizen being detained despite showing a copy in his phone: https://archive.is/0WXZR

Edit: actually I'm not sure if he got the chance to show the copy, that info seems ambiguous:

> The federal agents who detained Mubashir refused his repeated attempts to show them a copy of his passport on his phone or provide his name and date of birth to prove his citizenship, he said. Instead, they insisted he allow them to take a photo of him to make the verification, according to Mubashir.

In the thread "Roomba maker goes bankrupt, Chinese owner emerges" [1], I wrote about China'a hardware capability now going far beyond what US can imagine. In Dan's article;

>A rule of thumb is that it takes five years from an American, German, or Japanese automaker to dream up a new car design and launch that model on the roads; in China, it’s closer to 18 months.

Not only is China 3 - 5 times faster in terms of product launches, they would have launch it with a production scale that is at least double the output of other auto marker. If you were to put capacity into the equation as well, China is an order of magnitude faster than any competing countries, at half the cost if not even lower.

Every single year since 2022 China has added more solar power capacity than the entire US solar capacity. And they are still accelerating, with the current roadmap and trend they could install double the entire US solar power capacity in a single year by 2030.

CATL's Sodium Ion Battery is already in production and will be used by EVs and large scale energy storage by end of this year. The cost advantage of these new EV would mean there is partially zero chance EU can compete. And if EU are moaning about it now, they cant even imagine what is coming.

Thanks to AI pushing up memory and NAND price. YMTC and CXMT now have enough breathing room to catch up. If they play this right, I wont be surprised by 2035 30 - 40% of DRAM and NAND will be made by the two Chinese firms. Although judging from their past execution record I highly doubt this will happen, but expect may be 10-15% maximum.

Beyond tech, there are also other part of manufacturing that China has matched or exceeded rest of the world without being noticed by many. Lab Grown Diamond, Cosmetic Production, Agricultural Machinery, Reinforced glass etc. Their 10 years plan on agricultural improvement also come to fruition especially in terms of fruit and veg. I wont be surprised if they no long need US soy bean within 10 years time.

All in all a lot of things in China has passed escape velocity and there is no turning back. China understand US better than US understand themselves, and US doesn't even have any idea about China. I think the quote from the article sums this up pretty well.

"Beijing has been preparing for Cold War without eagerness for waging it, while the US wants to wage a Cold War without preparing for it.".
