> Think about how many people who support this stuff would be screaming bloody murder if some developer bought their neighbor's lot and coordinated with some other local developers to submit all their proposals for the most hard to approve stuff right at thanksgiving to take advantage of all the sped up paperwork and limits on how long government can sit on things and then built right up to the sidewalk.

Maybe show some of the negatives, your example as is doesn't sound that controversial.

I used to say "Never bet against Intel", it was because everytime they seemed to be behind they would pull something out and regain the loss in short order.

But so far nothing of the sort has happened for a long time. If feels like ever since Ryzen landed, they have been desperate to catch up but keep tripping on themselves. Losing Apple, while inevitable, has made them look even more irrelevant. They still do decent stuff for the most part but there isnt anything really exciting.

I do like what they are doing with Arc GPUs but it is clear those are loss leaders and it isnt really gaining that much traction.

Alas, this is a story where we will have a better understanding in five years from now.

You received some better corrections in earlier replies, which you've chosen to ignore... That's your prerogative of course, but there's no need to resort to "I'll have you know I graduated top of my class in the Navy Seals"-style reverse ad hominem to make an argument.

You made some basic mistakes in your previous reply, such as confusing power (kW) and energy (kWh) and assuming that a typical driver in HI commutes something like 250mi each day. This isn't even typical for drivers on the mainland, where plenty of EV+solar owners manage to replenish most or all of their EV usage using rooftop solar generation just fine.

(If you're going to answer "well, I never said I was considering the median distance/day case - I was talking about the most extreme scenarios!" then I'd suggest at least bumping up the hypothetical solar installation to 10kW instead of going with the median.)

It's not just about the extra life span, it's the quality of life until then.

I wish the same focus was given to weight loss, smoking, etc. No one really cares about living an extra 10 years from 70 to 80 if it means giving up 40+ yesrs of enjoying bad habits.

Exercise is especially neat because there are enjoyable ways to do it

i can't see how these numbers can be anywhere near correct (nor the ones above). in JavaScript on an old Core i5 the overhead of a simple ffi call is on the order of 5 nanoseconds. on a recent x64/arm64 cpu it's more like 2 nanoseconds.

you can verify this easily with Deno ffi which is pretty much optimal for JS runtimes. also, from everything i have seen and read, luajit should be even lower overhead than this.

you really shouldn't be asking chatgpt questions like this imo. these are facts, that need to be proven, not just vibes.

Depends on the game. Generally they are pretty close, outside of silly cases

https://www.phoronix.com/review/nvidia2022-windows11-linux

Has cyberpunk at 4K, high, 75 fps for windows, 67 for Ubuntu. In Steam Play, so that’s including some overhead. (There’s a bigger difference on silly benchmarks, like Portal in the .5 kfps range).

Cachy looks to be a little faster than Ubuntu in most benchmarks so it may be a wash compared to Windows 11 (which ought to be pretty shocking given that Linux is working with some comparability layer).

Treason has a high bar in the us, though north Korea is one of the few countries you could get involved with that could land you a treason charge, I believe a state of war still exists between the us and noko.

You're mistaking active calories as the only calories you burn a day. There's a reason the caloric intake recommendation is ~2kcal/day, because your RMR (resting metabolic rate) is ~2kcal/day. Meaning if you were to literally sit in bed all day, you are "burning" ~2kcal/day. On top of that you have your incidental energy expenditure per day (TDEE), aka walking to the fridge, taking a shit, general locomotion, etc. You then have active calories burned on top of that. If you were to run a marathon, that means you would need to eat ~5kcal in one day to break even.

If you actually read his post on the topic, he very clearly states:

"Our paper is largely a pedagogical exercise, with interesting realizations worthy of a record in the scientific literature. By far, the most likely outcome will be that 3I/ATLAS is a completely natural interstellar object, probably a comet, and we await the astronomical data to support this likely origin."

He's doing what scientists are supposed to be doing. He's proposing hypotheses that match the current data. Then science can continue gathering more data to try to disprove the various hypotheses that currently exist, to try to reduce it down to the one that fits best.

If you refuse to entertain hypotheses that match the data, even if they're unlikely to be the true hypothesis, you are not doing science.

It's the same pattern for the other times he's been in the headlines. He never says "X is aliens". He always clearly states that his various alien hypotheses are incredibly unlikely. You've gotten suckered into an incorrect view of reality by sensationalist headlines.

As we discuss in the FastLanes paper, the way BtrBlocks implements cascaded encodings (Vortex now) is essentially a return to block-based compression such as Zstd — which we're trying to avoid as much as possible. This design doesn't work well with modern vectorized execution engines or GPUs: the decompression granularity is too large to fit in CPU caches or GPU shared memory. So Vortex ends up being yet another Parquet-like file format, repeating the same mistakes. And if it still underperforms compared to Parquet... what’s the point?

We just released FastLanes v0.1, and more results — including ClickBench — are coming soon. Please do benchmark FastLanes — and keep us posted!

Exercise starts paying off in midlife by fixing your back pain, letting you go trampolining, steadying your balance, not getting winded or having to breathe through your mouth on stairs, and just generally making your body spend its repair cycles on things that make you feel healthy instead of inflamed. I develop so many aches and pains that exercise helps fix. Without the exercise you might not even want the extra 10-20 years.

A nice article on this was in the January issue of the Communications of the ACM [1]. With a reference to a piece by Dijkstra predicting that this is never going to be effective, back in 1979.

Being able to write code in a programming language is a feature, not a flaw. If we had always had to program in natural language, the precision and unambiguity of programming languages would be an eagerly welcomed revolution.

sorry. I was responding to the part that says that "Healthcare in the US is already in very poor shape."

Is AI better than most physicians for diagnosis ? I doubt it, and I doubt that there have been any real studies as the area is so new and changing.

My personal experience ? I am actually quite impressed, and I am an AI skeptic. I have fed in four complex scenarios that either I or someone close to me was actually going through (radiology reports, blood and other tests, list of symptoms, etc) and got diagnosis and treatment options that were pretty spot on.

Would I say better ? In one case (this was actually for my dog), it really was better in that it came up with the same diagnosis and treatment options, but was much better at providing risks and outcome probabilities than the veterinarian surgeon did, which I then verified after getting a second opinion. My hunch that this was a matter of self interest, not knowledge.

In two other scenarios, it was spot on, and in the fourth case it was almost completely spot on except for one aspect of a surgical procedure that has been updated fairly recently (it was using a slightly more old fashioned way of doing something).

So, I think there is a lot of promise, but I would never rely solely on an AI for medical opinions.

Bodybuilders eat a lot in the offseason because they're on tons of drugs and trying to maximize the amount of lean mass they can put on, and they eat more in general because when you have 100lb+ more muscle than the average person you have a significantly higher base metabolic rate. You can go on a variety of PED related forums and find IFBB pro's posting food logs, etc., and see that these crazy eating routines are limited to certain parts of the year, and even then have been falling out of favor - the 'lean bulk' for pros is more popular than ever.

Very few IFBB pros are working out in 2 hour sessions, either. Coaches understand junk volume way better now and know that a lot of the work being done previously just wasn't providing much muscle growth stimulus after a certain point. Most are spending <8 hours in the gym each week in general.

The top of the bodybuilding field is not eating a ton of food because of their lifting routines burning a bunch of calories.

> It's not like C++ users don't say the exact same thing about String, though.

If they do, they're wrong, as the two languages are quite different here. In Java, String requires two allocations: your variable is implicitly a pointer to String allocation, which in turn has a pointer to a char[] allocation. In C++, the std::string itself is a value type. The actual bytes might be inline (short string optimization) or behind a single allocation accessible from the std::string.

Rust's std::string::String is somewhere between: it's a value type but does not have a short string optimization (unless you count the empty string returned by String::new).

> Different people and programs always have a different notion of what a String should do (Should it be mutable? Should it always be valid UTF-8? Which operations should be O(1), O(n) or O(n log n)? etc.)

Sure, there can be call for writing your own String type. But what's unique about Java as compared to say C, C++, Go, Rust, even to some extent C# is that you can't have a class or struct that bundles up the parts of your data structure (in the case of a mutable string, two fields: data pointer/capacity + the used length) without boxing. There's a heavy cost to any non-primitive data type.

This is misguided. A healthy lifestyle doesn't simply mean extra decades at the end of your life and everything else remains the same. It means many health issues also start later and you have more healthy years available to in your younger years as well. Many turn 30 and already find some things ache or don't work quite the right way. Take care of your body and those risks drastically go down, it doesn't take ten hours a week.

The details of how we try to bend our capitalist system do not interest me because it is an inherently broken system. It is because of selfishness like yours that we will all die in the climate catastrophe.

> As an open source project no one is forcing you to maintain it.

Sure but thats not the spirit that built the modern software world. Our globabl information infrastructure heavily heavily relies on OSS and that has open source devs assuming some responsibilities. If not from others then just their own sense of self respect and engineering pride.

The only issue was that companies were exploiting that and demanding the exact labour that benefits them. Which is bullshit. And this might solve that

It’s the same thing, right?

That is, exercise may not necessarily make your life longer, but has a good chance of making your life higher quality.

Similarly, bad habits can shorten your life, and even if it doesn’t, will most definitely make your life lower quality (eventually).

Or maybe that’s the point you were making?

I hand curate github.com/underlines/awesome-ml so I read a ton about latest trends in this space. when I started to read the article, I felt a lot of information was weirdly familiar and almost outdated.

the space is moving fast after all. they just seem to be explaining QLoRA fine tuning, (yes great achievement and all the folks involved are heroes) but reading a trending article on HN - it felt off.

Better, yes. The market has grown a ton, and was ranked #1 in the country recently. Our tax base is weak, which makes it hard to compete with GVL and CHS, plus we have worse weather.

But the Bull Street district is in a totally different place from when you were here, which creates a feeling of “coming liveliness.”

Also Scout Motors is dropping a multi billion dollar plant in Columbia which will help job market

Definitely not Greenville, but we are getting there.

Human bodies are highly efficient at certain movements, e.g. walking. There's also a complicated part of hunter gatherer life style where you don't know if you'll find something if you walk another mile, so often the response is to just... not do that.

Being able to have a life style where you're constantly expending energy, like training athletes do, really only works if you're guaranteed food, which is generally not how hunter gathering works.

My desktop is now about 12 years old with a 1650 GTX GPU. Still does everything I need perfectly fine. It is funny seeing some lower powered offerings with iGPUs that run circles around this thing. It is looking like my next machine will probably not have a dedicated GPU, at least at first. The intergrated stuff is pretty decent when the newest games you have are about 4-5 years old or just target lower specs.

I've listened to Avi Loeb on Mindscald and he was quite clear that he's taking the possibility seriously as any scientist should take any possibility seriously. He did strike me as a crackpot, but just as somebody who thought that this field has been stigmatized and ridiculed for a long time and somebody has to have the courage to remove the stigma and take this field back in the hands of real science.

I only listened to that one podcast and it was at the time of oumuanua I don't know if in the meantime he veered completely on the crackpot side.

I'm sure there's a zillion other normalization methods for different things.

I wouldn't even consider a nuke for that. Energetic plasma ball resulting from nuke is not effective method to do so and any debris that survives the explosion isn't going to still be in LEO, but also no plausible deniability because it's obviously a nuke.

Try "we launched a satelite and it RUDed (honest we pinky swear it wasn't just a loose heap of ball bearings like it appears on radar) and now LEO is marginally more dangerous".

The point of the saying is to get most people to understand that the biggest factor in the average person's weight loss is their diet, not their exercise levels.

Pointing out that elite endurance athletes and olympic athletes can have high calorie requirements isn't helpful or the point. Yes, energy must come from somewhere, but even among the generally fit and active portion of the population, only a vanishingly small number of them exercise at the intensity and time requirements to burn so many calories as to not easily have all of that thwarted with a single meal.

IMO it's not the recording of ideas that is thinking, but rather the act of putting thoughts into language. To me there isn't a big cognitive difference between conversing about a topic (during which you put thoughts into words) and writing about it.

When you speak or write instead of just think, you create something that did not previously exist: new words and sentences. When you write instead of speak, you aren't exactly creating something new — you're often just recording words that just as well could have been spoken. Using an LLM is much closer to the first case. It's creating something that didn't previously exist (an expanded thesis on a brief thought provided by you), and therefore seems to possibly risk the user's ability to think atrophying.

> dataclasses are, um, classes

So is the case when you use `namedtuple`, which creates a new class. This is not an interesting gotcha.

Classes (the Python language construct) are how you implement records (the language-neutral concept) in Python.

It's ironic that the "There Is Only One Way to Do It" language has multiple bad ways to implement records though.

It seems like it's more often than not that I'm coming across dishes that just do not make sense, or are poorly plagiarized by someone who doesn't understand the cuisine they're trying to replicate with absolute nonsense steps or substitutions or quantities. I used to have a great success rate when googling for recipes but now it's almost all crap, not even a mixed bag.

I've been driving a Chevy Bolt for over 8 years now, and I regularly use the regen paddle. I drive in "L" mode, which engages partial regen when the accelerator is released. When I need more slowing, I pull the paddle, and that increases the aggressiveness of the regen. I only press the brake for quick stops, or to hold the car once it has stopped.

I also use the built in "hilltop reserve" feature, which limits charging to 90%. This ensures that there is always regen resistance, and therefore a consistent experience.

We populate our corporate leadership with non-founders so highly compensated that actually succeeding does not matter to them. They've already "won" at the game, and they spend a lot of time posturing with respect to each other. They set the membership criteria for the "club", reinforce each others' positions, and use the ability to bestow membership to manipulate the political system away from regulating or taxing them.

In other words, I completely agree.

The program in the article is obviously racy according to the Go language spec and memory model. So this is all very much tilting at windmills.

I broadly agree with what you're saying, but, that's not the issue here.

They don't even have a dedicated status/outage page, afaik.

The website being down is a more classic problem. The outage probably increased traffic to their website by 1000x if not more and the infrastructure for the website simply couldn't cope.

Good lesson on keeping your status infrastructure simple and on something which is highly scalable.

Having a CDN where the main page of their site was 99% cached globally would have probably mitigated this issue.

Minor correction. Athlon arrived at 500MHz, 550MHz and 600MHz. But they were still a big shock when they arrived. They were the first chip in a long while to really take on Intel and succeed.

The 650MHz came two months after than, and 700MHz another two months later. 6 months later 1GHz! It is easy to forget just how rapid performance increased in the late 90s.
