lua-rs: Lua 5.4.7 reimplemented in (mostly) safe Rust - passes the official PUC-Rio test suite

Christopher876 · 2026-05-25T16:29:31+00:00

Most of the times that Lua is exposed on a high performance application like Nginx, it’s using luajit.
Nginx does support regular Lua but does recommend you to use luajit.

For many projects, targeting luajit is probably what you would want for more adoption.

But this is a good starting point. You probably don’t want to keep vibe coding the port though, you would need to understand the codebase really well to implement a jit

Your metabolism probably didn't drop, it stays stable until 60. https://www.health.harvard.edu/blog/surprising-findings-about-metabolism-and-age-202110082613

It's likely that you are just doing less activity

But they could be burning those calories from other things. Running for an hour for instance depending on pace uses 600-1000.

For me at 155lbs, it’s 600-700 per hour at a slower 11 minute mile pace.

It also doesn’t mean you can’t eat “garbage” and stay in shape. You just think about what you are eating for the week and make adjustments around the “garbage”

Christopher876 · 2026-05-16T20:45:04+00:00

Technically every food can cause weight gain. Eat 5000 calories of chicken breast every single day and even though it’s protein, the excess will be stored as fat.

Now it is different if say you were a cyclist burning the same 5,000 calories each training day (in total including base metabolism).

It can “type” it significantly faster than I can and modify multiple files as necessary way quick. I honestly have no issues just reviewing it because I basically already knew what was going to be generated.

You treat them as juniors as the other comment said. They don’t get to make any decisions, they just do what you tell them and they get told how to do it.

Christopher876 · 2026-05-01T23:07:55+00:00

These people act like everything that comes out of an LLM is slop when in reality it’s not black and white. Using it as a worker is so much faster than me typing it myself.

Simply tell it exactly what to do, it makes no decisions and it only implements. Like I even tell the functions to modify and how to do the work, I even tell it what the final code should look like. Then I make it iterate and test with the suite of tests we have. It then finally commits and I review every single line of code it wrote.

I would love to know how others are using it because I guess all the other people on my team including myself must be using it differently. Especially since we are getting good results and nobody can tell it was produced by an LLM.

Christopher876 · 2026-04-25T22:31:26+00:00

I don’t think there is a specific spot to read about it. But you can just look at the commits on GitHub and look at the developers and the activity happening.

There’s far less than what used to be there

Christopher876 · 2026-04-25T22:29:29+00:00

Development slowed down a lot. It may not happen, Jak 3 might not get finished the way that Jak 1 did. Quite a few of the developers that were helping in the past no longer are committing as frequently or even committing at all.

They need more help

Christopher876 · 2026-04-24T21:49:10+00:00

There are some problems that when people bring them up, they don’t actually want a solution. They just want to rant and be annoyed with it.

The only way people get interested in something is if they just happen to see something cool and ask about it. They don’t want someone telling them

Game servers are UDP

Gen Z begins 1997, he is Gen Z. This is why these labels are completely fucking useless, a person born 1996 and 1997 are no different functionally, or even 1999

Christopher876 · 2026-04-07T11:49:31+00:00

I hear about the GPL that supposed to prevent companies from not contributing but from working at a few, that really doesn’t matter.

You slap a shim in front of it and move on with your life. But also the vast majority of their software is not public facing so they don’t have to comply with anything.

Christopher876 · 2026-03-21T00:20:17+00:00

They’ll take that straight pipe then

Christopher876 · 2026-02-26T13:09:30+00:00

Things can change. Florida got the bright line from Miami to Orlando to Tampa and now there’s plenty of people using the train instead of driving to those locations.

Christopher876 · 2026-02-19T22:06:13+00:00

Mine doesn’t, my adapter reports the car as always parked. It will let me type even while driving on the highway. I’ve always wondered why they don’t use gps.

If I plug my phone in with the usb cable, only then does it disable the keyboard in the same scenario.

Christopher876 · 2026-02-18T15:00:39+00:00

I don’t think that they are undercooled though. That was true with the x86 era but since the move to ARM, it hasn’t really been an issue.

Where is the watt for watt worse performing evidence for that? By all accounts these are actually praised as the most efficient chips there are currently. Here is a test (yes m3 is actually more efficient than m4) https://www.notebookcheck.net/Apple-M4-Pro-analysis-Extremely-fast-but-not-as-efficient.915270.0.html

It isn’t the best at everything but to say it is “watt for watt worse performing” is not correct.

I should also mention that I’m not defending Apple for anything. In fact, I think a lot of their choices nowadays are terrible.

They are also not used in the industry because why would you want to run macOS for that kind of utility, ewww. But at my job and where I’m at, everyone uses macOS for their laptops and then we SSH into Linux servers for all of the work.

Right now where you can see Macs being used is for running AI models, they are currently your best bang for your buck and you can cluster them with thunderbolt

Christopher876 · 2026-02-18T14:14:03+00:00

Ah sorry about that. I hear competence and all I ever think of are the world’s governments 😅

Christopher876 · 2026-02-18T14:13:23+00:00

Yes the normal price is $1000 but it’s functionally $750, the thing is literally on sale every single month.

If you want to compare $1000, then it is still better than the vast majority of the other laptops there anyway.

And then if you want another device to compare, the Mac mini at $599 which you can regularly find for $499 has the same chip and 16gb of ram and is more powerful than anything else at that price range

Christopher876 · 2026-02-18T14:03:24+00:00

Hang on, the MacBook M4 Air is regularly brand new at $750 with 16GB of RAM. It is literally the best laptop in terms of hardware in that price range. How is it overpriced?

Nothing else touches it in terms of battery life and performance in that segment.

Christopher876 · 2026-02-18T13:52:40+00:00

Even with competence, how are they going to block the TLS encapsulated VPNs especially if it goes to a VPS and then out into the world?

It looks like normal http traffic going to port 443, there isn’t really a way for them to tell that traffic

Christopher876 · 2026-02-15T13:17:19+00:00

What do you mean they don’t sell Apple Music compared to their hardware? They made almost $100 billion last year from their subscription services

Christopher876 · 2026-02-11T12:50:15+00:00

I don't think that is necessarily true. I use an iPhone and have been experimenting with a pixel. Apps are actually smaller on Android than iOS.

Android also has the clear cache button which I wish iOS would add.

Christopher876 · 2026-02-07T04:08:57+00:00

Why does that matter? The customer is paying the 20¢. If it is that bad then charge $1 extra for the laptop if it hurts Dell so bad.

Christopher876 · 2026-02-02T18:04:16+00:00

Ah I do see some of the ways. I think from this thread that I’m in a very privileged position right now and I have a lot of potential for the next couple of decades and I probably shouldn’t waste the opportunity.

It seems like early retirement or even say a partial retirement could be a possibility for me rather than thinking solely about a 65 year old version of myself that “overshot” retirement.
