lanza··on A whirlwind tour of the LLVM optimizer
> Yet why do languages end up depending on LLVM and not implement these algorithms on their own and avoid a monstrous dependency?

That's like asking why construction companies rely on cranes, concrete and steel rebar when they can be using sticks, leaves and vine.

LLVM is so mature that it's hard to improve it. If you don't care about the performance of your languages code then fine, use leaves and sticks and moderate winds will knock down your shelter.

lanza··on Google I/O: Big changes coming for SEOs with ubiquitous AI
Why do people post worthless anecdotes like this when we know from trivially available data that Google makes over a hundred billion dollars per year from search.
lanza··on Meta open-sources multisensory AI model that combines six types of data
You don't understand what opensource means...
lanza··on Google “We have no moat, and neither does OpenAI”
I mean... your argument is structurally the same as his. "I once saw X happen and thus X will happen again."
lanza··on Meta Q1 2023 Earning Results
> If almost every post is an ad, then it makes sense. Like others have pointed out, 70-90% of content is an ad on Meta platforms.

If you start your statement with hyperbolic nonsense why would I care to read the rest of it? I just checked IG reels and I went through 36 reels before getting to my first ad. I admit that is way more than I even guessed it would be, but pretending 90% is reasonable is a joke.

> Facebook seems to be floundering.

The link that we're literally replying to just described that it's growing in all major metrics. Stop letting niche internet communities for clingey geeks over-influence your world views.

lanza··on Quantum physics falls apart without imaginary numbers
I'll make sure to let my PhD advisor know he was wrong about me since that's clearly under your jurisdiction.
lanza··on Quantum physics falls apart without imaginary numbers
Classical mechanics are fundamentally wrong. They are low energy approximations to reality. "How did the bal go through the hill when it actually didn't have the momentum to do so" is a nonsense question because the equations of motion you are attempting to use to describe the phenomena are wrong.

You can't and shouldn't try to understand QM from a CM standpoint. If you remember Taylor series expansions, this is like trying to understand `sin(x)` by looking at it's first order Taylor series expansion `x`. Your question about momentum and a potential hill is the same question as "how did the value of sin(x) start decreasing if `x` is linear?" You're using too few terms of the series expansion. The mechanisms of Newton's laws are first order terms of a proper QM solution.

lanza··on 1-in-1000 year flooding in South Florida
From looking at a few different climate charts, Tampa seems drier, but still 1.8 inches. Where I live (Orlando) it averages 2.6 inches this month and weather forecasts have it raining twice over the next week and there was a thunderstorm earlier today.

I guess from having lived some time in north and south California I assume "dry" means "actually dry" as in "it's not going to rain at all this month".

lanza··on 1-in-1000 year flooding in South Florida
I've lived in Florida over 30 years. Mostly in the South, but also for stints in central and northern. I've literally never heard of a "dry season." yay-it's-not-raining-every-single-day-and-the-grass-isn't-flooded-season sure.
lanza··on Show HN: ChatGDB – GPT-Powered GDB Assistant
> When I had to use a dissasembler the issue was not commands, because those become muscle memory after a few hours of use.

My few hours of usage is 30 different 5 minute stints over the course of 6 months. I don't remember anything between usages. English debugger prompts will be amazing.

lanza··on Transformer architecture optimized for Apple Silicon
OpenAI is big tech. Also, Apple has nowhere near the AI/ML staff that the rest of the tech giants have.
lanza··on Fed hikes rates by 0.25 point despite recent turmoil in the banking sector
> That is something like saying "the house is not falling down" - you don't need to say it if the house isn't at risk of falling down. I think the statement is true right now, but they are hoping to stem the bleeding on bank balances.

If somebody asks "is the house falling down" and you ignore the question then that's worse than responding "no."

lanza··on Twitch.tv Lays of 400 Employees
> Wait, I thought revenue was growing! How is that not sustainable? If you just leave costs where they are and let revenue grow, you are by definition sustaining/growing the bottom line.

Come on man, if you don't understand how a business can be showing signs of unhealthiness while still increasing revenue then don't post. That's such a trivial superficial analysis of reality.

I'm not going to pretend to know or understand enough about Twitch's business to agree or disagree with whether they need layoffs. But a shallow comment of "revenue go up" is lowbrow nonsense.

lanza··on More students are turning away from college and toward apprenticeships
I'd definitely explicitly add business to the first entry. Sure you can work in business without a degree, but the experience with the mathematics and ideas that you learn is definitely a huge benefit.
lanza··on Docopt.sh – Command-Line Argument Parser for Bash 3.2, 4, and 5
As a very fluent user of shell scripting, nothing in shell scripting is idiomatic.
lanza··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
> I just hope nobody forgets how prominent VCs behaved during the brief period of uncertainty. The idea of some noble class of investors championing disruption is dead. They're just a bunch of rent seekers like everybody else. For some silly reason I had some respect for the startup industry before this, now I see it as a joke.

You have some serious disillusion.

lanza··on Cargo cult science (1974)
Eh, your analogy isn't apt. The problem in physics is that the space of possible theories has been searched so exhaustively that what these physicists are doing is just about the only choice.

To make your analogy close to physics -- imagine you found a unicorn horn and can tell from the biological makeup that it is indeed a horn grown from some sort of horse-like mammal. If you searched 99.9999% of the earth for animals that might have grown that horn and found nothing then the best thing to do would be to continue looking within that 0.00001%.

We can't figure out what comes after the standard model of particle physics. But we know it's wrong. e.g. we know black holes exist and something has to happen within them. But we don't have a theory that can predict what that is. e.g. we found a unicorn horn. So we have to desperately search for it.

Hossenfelder is right that it's shitty to have to keep pushing the energy boundaries in which we hope we'll see some interesting behavior. But there's literally nothing else to do. We've searched 99.99999% of earth and there's no unicorn. Do we start denying the existence of the unicorn horn that we're holding?

lanza··on Will Carbon Replace C++?
He didn't staff a team of compiler engineers to do it. Doesn't matter how good it is when mature languages that reach the mainstream all have compilers funded by 10 people at a tech giant and cppfront is just Sutter screwing around in his free time.

Google threw the weight of their top C++ engineers behind Carbon. It's happening. That's really what matters in the world of programming languages. Not how good it is.

lanza··on I use C when I believe in memory safety
I've experimented and liked it, but the odds of a language exploding in popularity without a massive investment from tech giants is nearly zero. It's not "may the best language win."
lanza··on Fedora now has frame pointers
Eh. If you worked at google you'd know that 1% performance improvement for C++ is measured in the 10s-100s of millions of dollars.
lanza··on Show HN: I trained an AI model on 120M+ songs from iTunes
Neat, but I'm convinced after giving it a try that this is absolutely not the way to do music recommendation. The recommendations were complete misses for me.
lanza··on Meta Reports Fourth Quarter and Full Year 2022 Results
My personal bet is that the tech giants are immune from US regulation. Hurting a tech giant just means that that market position goes to Asia, most likely China.
lanza··on ChatGPT Plus
People are so cheap it's ridiculous. If we ever get past people being unwilling to pay for software beyond rates of 1 cent per hour tech will blow up to 10x as big as it is right now.
lanza··on Why WhatsApp Only Needs 50 Engineers for Its 900M Users (2015)
> I understand enough ML to know how

hmmmm

> We can even think about having a standard to describe and document ML systems (and I would totally look that up because I have the right to know how my keyboard suggests words, why this search result that seems unusual is in fact a sponsored placement, or why this autonomous vehicle chose to run over the pedestrian so not to kill the baby on board...).

Yea you know nothing about ML...

lanza··on Apple: The only big tech giant going against the job cuts tide
This is such a weird topic. The comparison is between companies that didn't exist 20 years ago like Meta and the 50 year old industry veteran Apple. Of course Apple didn't hire as fast, they were established. That's like saying a 20 year old college student grew more over the past decade than a 40 year old engineer. Yea, that's how life works.
lanza··on Script Kit: cross-platform, scriptable, automatic shortcuts to everything
> But... Other than the standard library, which might be useful, all of this is already possible. Just write your scripts _in any language_ and launch them via the universal launcher: the command line.

How do you not understand why people would want to do something faster than they typically do it?

lanza··on I have reached Vim nirvana
> The keybindings are really the unique selling point of Vim, and you can get them anywhere.

How you know somebody doesn't have a clue what they are talking about.

That's like saying "chess is a bunch of nerds playing chess with more pieces."
