> Once network IO became the main bottleneck, the faster CPU mattered less.

It is surprisingly hard to keep a modern CPU core properly saturated unless you are baking global illumination, searching primes or mining crypto currency. I/O and latency will almost always dominate at scale. Moving information is way more expensive than processing it.

C++ compilation can do this trivially, as long as you have enough RAM.

Came here hoping someone would mention those absolutely cursed cameras - the ones with the pre-canned video of a guy in a back office "monitoring" the feeds?

Gets to me the worst when I'm on my 3rd Home Depot trip of the day BEEP looking through a box of pipe fittings that is filled with everything _except_ the fitting matching the label on the box BEEP okay.. the Home Depot website says it's in stock at the one 20 minutes up the store BEEP but, that's what it said about BEEP the stock at this store so.. but hmm BEEP maybe I could combine these two other fittings and save a BEEP ... trip to the other store, okay I'll look here for... BEEP hmm, the two fittings I would need to combine also aren't in the right BEEP box, but... it looks like maybe there's some that someone put back into a BEEP different box? Oh, wait BEEP _none_ of these fittings are in their correct box? What!? BEEP

Sorry I've just never had anybody to talk with this about. I hate those things with a passion. Let me know if you'd like to start a support group.

And yet, we keep going here...

There are fewer and fewer physical stores left that sell non-food for reasonable prices. Home Depot is often the only choice (at least in my area, the competitors, Lowes and Ace Hardwares, are more expensive, sell fewer things, and sometimes worse quality too)

What's the purpose of the green square, anyways? Why not just have a regular camera feed?

Increase deterrence effect to scare away shoplifters.

Home depot goes out of the way to make its cameras visible. There is a large "camera" sign, bright light to catch your attention, a visible display to show it's not a fake, and sometimes even a motion activated chime. I assume the green square around the face is the next step in a game.

Ok, so the author thought it's a great idea to embed a little mini-game onto the page - in case two squares shot by the things in each bottom corner ever collide, your mouse cursor vanishes. Brilliant - tab closed.

PS. fix the origin of the projectile shooters - right now they are shooting from the "side" and it looks sloppy.

I spent some time trying to disable those with uBlock but they kept hiding once I entered the picker.

And then I've realized that uBlock has an option to "disable all JS on that website" - and that worked wonderfully, and stopped vanishing cursor too.

Recommend everyone does the same.

theamk commented on What if the universe runs on recursion, not particles? A new formalism   ktynski.github.io/FIRM-Fr... · Posted by u/kristintynski
kristintynski · 9 days ago
Background: I built a new theory of everything with GPT-4o in 6 weeks. No curve fitting. 19 physical constants derived from recursion and topology. It’s called FIRM — and it might be real. or, im just another crackpot. But im a crackpot with a shit ton of code and experiments!

Thesis: Physical constants don't just happen to have the values they do. They are the unique stable solutions to recursive mathematical equations—the only values that allow the universe to be self-consistent.

Answer: Who tf knows, this was the wildest AI driven rabbit hole I've ever been down, and its not even close. Maybe some of you can help me figure it out? Is this really showing what it seems to be?

Physicists, Cosmologists, Mathematicians. Is there something to all this? It feels so parsimonious, and the math is working (at least as far as I can tell), but claims this big obviously require absolutely massive evidence.

So please, rip it to shreds if you can.

There is nothing to it.

> The first statement says: α⁻¹ = 137 + φ⁻⁶ [...] = ≈ 137.055728 > Experimental value: 137.035999084 (0.014% deviation)

The value is well measured, and it is known with up to 10 significant digits (the relative uncertainty is less than 1e-10). Your formula has error of 1.4e-6, over 1000 times worse. This means it simply does not match reality. (And I am ignoring where did this "137" that just came out of the air).

Other constants have similarly large errors compared to experimental uncertainty.

You don't have a new discovery, you have a typical AI hallucination.

Meh. To be fair to the models, I would have at least flagged some of the same things to actually check myself, if asked to review. What OP can do is task the models to actually break into it. Have it running in a container, have the agents come up with, implement and actually run tests for this. And only report successful attacks. Things might change.
theamk · 10 days ago
That may be a sensible approach, but in practice there are many companies, including Github, that offer AI reviews today - and they have the same general quality as author's examples, that is "mostly junk, with occasional completely incorrect code and very rare actual problem"

(This depends on your field too.. I suspect that if you are doing Yet Another Social Media in Typescript the reviews would be better; but once you step off the beaten path, quality drops rapidly)

Nice, this matches the kind of reviews that Github's Copilot makes on PR.

This is such a strange position on usage-based pricing and seems telling.

theamk · 11 days ago
Seems reasonable to me? After all, they went to "predictable pricing" which seems to be generally better than usage-based one.

I think the only reason to go with usage-based pricing is if you want to take a risk to save money - you are getting unpredictable bills but hope that average is going to be cheaper. As any gamble, you can win or lose.

You don't even need a physical connection.

As long as you have two-way wireless communication (which any keyless entry/start system does), then you can simply do a Diffie-Hellman key exchange during the pairing process.

Diffie-Hellman is designed for exactly this usecase, allowing two parties to derive a shared secret key over a public channel without exposing it.

theamk · 13 days ago
Given how bad the "single master key" idea is, even simple update like "transmit secret key in the open, but with reduced power, during paring mode", would be a great improvement.

It'd instantly mean there is 0% chance of someone figuring the key based on day-to-day operation.

theamk commented on Don't use Redis as a rate limiter   medium.com/ratelimitly/wh... · Posted by u/5pl1n73r
Magmalgebra · 15 days ago
I wish the article talked more about why people use Redis as a rate limiter and why alternatives might be superior. Anecdotally I see the following play out repeatedly:

1) You probably already have Redis running

2) Adding a "good enough" rate limiter is easy

3) Faster solutions are usually more work to maintain given modern skillsets

If you are a b2b SaaS company odds are your company will exceed 10 billion in market cap looong before Redis rate limiting is a meaningful bottleneck.

theamk · 15 days ago
The superior alternative is clearly author's startup. Who does not love 3rd party, cloud-hosted service in critical dependency chain on every page of your website?
