bruce343434··on Tank Body Problem
Took the words out of my mouth. The trajectory indicator isn't predictive either, making it pointless. A single playtest would have made this obvious and maybe even a single prompt would have solved it.
bruce343434··on Why isn't mutable a subtype of immutable, or vice versa?
So really there are 2 orthogonal axes:

- A: can I change the value

- B: can something else change the value (can I depend on a predictable stable value)

Because the axes are orthogonal, hierarchical based subtyping (inheritance) breaks, but type classes (interfaces), ad hoc polymorphism, would work.

In C, const answers A

In rust, due to pointer aliasing restrictions (either one mut pointer xor any amount of read only pointers), (lack of) mut answers both A and B

bruce343434··on How Swiss tables work in Go built-in map
I feel like this article does a depth first search on what swiss tables are, jumping head first into the tiniest implementation details, but I'm missing the breadth first search. What is the top level `struct` of a swiss table? An array of groups? Why not simplify all of it into linear open addressing, with a stride of 8 for simd? Why the triangular jumps? What problems does this design solve?

bruce343434··on The LLM Critics Are Right. I Use LLMs Anyway
> last month I spent almost 10k USD on tokens. It sounds so insane

It is. That kind of money would change my life and this guy spends it on prompts that "really force him to think".

I use LLMs. So far, 20 bucks per month has me covered. I hit the limit sometimes. I just take a walk. Forces me to think.

addressing any of the points would require locking the AI down and making it less general and less "agentic". Your concerns make sense if you look at the AI as an information retrieval engine.

   - why is single URL crawl with 20+ redirects not flagged as problematic and/or aborted?
There could be legitimate use cases for interacting with a website like this that could serve the user.

   - why is a query about a coffee place based on its public URL even seeded with the users' context and confidential information? 
Because it provides context in how the agent interacts with the site (in this case to detrimental effect)

   - why dont they just look up the coffee place on a trusted source like google maps and continue from there?
The ai was explicitly instructed to check the given url

   - why is the basic "social" engineering style attack working?
because ai can not separate prompt from information, they share the same input channel. state of the art ai has some amount of "common sense" as to when it is being prompt injected or engineered, but this isn't exhaustive

   - why is the cloudflare impersonation not challenged if the website is clearly not from cloudflare and there are zero references from cloudflare to this website in the training corpus?
because the ai didn't think to check if the website is truly behind some sort of cloudflare product or not

Is there a nautical map equivalent of osm or organic maps? One that emphasizes waterways by drawing them thicker when zoomed out like regular maps draw roads thicker? Plan routes over the water? Even google maps lacks a nautical layer.
bruce343434··on LuaJIT 3.0 proposed syntax extensions
Because you can deduplicate certain parts of the logic which make the whole thing less error prone, such as

    if c
      x=1
    else
      x=2
If I ever want to change x, or refactor this code some other way, its a more brittle process over x=c?1:2

The ternary expression also takes up much less space so there is less of an emphasis on it, this can be a stylistic tool in a programmer's toolbox

tldw:

- wider wheels are marginally less efficient but almost negligible

- rims with larger diameter have larger air resistance. Probably because the rim patterns intersects the air in weird ways but it's not explained. Tire walls are relatively smooth, so tires with higher aspect are way more aero-efficient despite having more marginally lower rolling resistance.

Why would the company pay more when they can just not pay more? The only things I can see happening is they might lower prices as competition ramps up, or in general as there is more supply for the same cost.

Everyone else will be 5% more productive. Then no one is "more" productive. So everyone has a higher output, but the same wages and hours worked. There was only a gap when usable AI first came out, some contractors could do the same quantity of work in less time and enjoy time off or do more jobs. Now the gap has closed or is closing. And using AI now is more about not being less productive than peers who do use it.

bruce343434··on 1k Data Breaches Later, the Disclosure Lag Is Worse
The issue is how easy computers make everything, and how well processes scale with computers. Back in the day to heist data you'd have to physically break in or infiltrate, rummage through files, copy them somehow or just straight up take them. In a briefcase?? How many files can you exfiltrate per day like that?

But on a database it's practically a matter of running a copy command and uploading it or exfiltrating it. And there will always be software vulnerabilities.

Computer processes have no inherent rate limiter to them, and they even allow you to run stuff from a distance.

bruce343434··on Did Claude increase bugs in rsync?
I agree. I tend to use the gnu "asprintf" which simply returns a properly allocated char buffer with the formatted string in it. And on platforms that don't feature asprintf (windows) you can build your own using sprintf!
bruce343434··on Show HN: Soft Body Jiggle Physics
The accumulator pattern keeps simulations stable in the face of variable frame rate. Accumulate the frame dt into an accum variable. If accum>fixed_physics_dt then step_physics until false. I'm assuming the author did something like that because it's standard practise.

bruce343434··on Did Claude increase bugs in rsync?
I'll change your mind:

If you pass NULL as the destination pointer, it doesn't write any string. If you combine this with %n at the end of the format string, you can get the exact length that the output string would be. Then you allocate that, then you print again, into the actual destination buffer this time.

what happens when ALL the stocks have been bought back? what is the natural conclusion? you get extra points if you mention dilution i.e. oops we turned on the ~~money~~ stock printer and your stock is now actually worth less!

That's just dividend stocks with more shady. We promise to invest the dividend you would have gotten into ourselves to become more valuable bro. But that will only be reflected in "valuations" that don't directly affect your bank account. It is still the greater fool theory.

The worst is growth stocks that are a wrapper around actual dividend stocks. Beyond number going up, what actual concrete utility are you getting? Beyond waiting for the line to go up to eventually sell it to a greater fool, what can you _actually_ do with it? It's not real.

It is only real because enough people believe it is real. And they believe it because they want to believe it, because they are greedy and want easy money.

Once the market tanks and the greed turns into fear, there will be bagholders and the brokers will be laughing. The people who skim fees and percentages will be cozy.

"Now is the time to invest" they will say, because from here the line can only go up! And it will, eventually, because people want to believe, because they are greedy.

The only thing the stock market makes money on is greed. That is the thing that drives stock value. Not the economy.

> not concerned about the actual economy.

Why would it be? Non dividend stocks only have value because other people think they have value (i.e. greater fool theory).

Only dividend stocks have some base value connected to how well the company does. (Higher dividend if it does well, lower if it does poorly.) But they still also have a lot of "greater fool" value.

Beyond dividend, stocks have no intrinsic value. Nowadays you don't even get a piece of paper to wipe your ass with anymore, it's all digital.
