Jev-Leftpad

Man-made horrors beyond my comprehension, neat.

Now that's a rare GitHub Username!

Though, again, a yet another project for a yet another "AI" to make someone else more dependent on it...

Uses JEV to do something that's one line of code. Also, "leftpad" was a useless package from years ago that many important packages used instead of writing the code themselves. Its outage at some point broke a lot of packages.

1h agoHN ↗

why useless? it did one thing that js didn't natively do

1h agoHN ↗

It did one thing that you could write in one line of code. But it wasted space as a packaged dependency instead.

1h agoHN ↗

Jev is a new type of model that just makes decisions based on given options. It's small and really really fast.

Leftpad is a npm package that chooses if it should or shouldn't pad the left side of a string. It was famous for bringing down everyone's npm installs a few years ago.

This combination is a double joke. Put something stupid in something stupid.

2h agoHN ↗

Please don't use this in production. Or anything important.

5 to 10 years from now, after this has worked itself deep into the npm dependency chain, we'll be lamenting how Jev-Leftpad is causing outages in critical services.

2h agoHN ↗

On the npm doomsday thing, the scarier version is someone vendoring it and the padding silently drifting between runs.

1h agoHN ↗

Make sure to vendor this package if you want reliable operation.

    it('trusts Jev when it chooses the wrong amount', async () => {
    answer('space_2');
    await expect(leftPad('jev', 8)).resolves.toBe('  jev');
    });
1h agoHN ↗

This means the package can add between 0 and 10 spaces. If more than 10 spaces are needed, Jev has no correct option. Which feels appropriate for this project.

I'll raise a PR which uses Jev to check if the target length is beyond this range

1h agoHN ↗

I thought you were doing a PR to add an 11th space.

42m agoHN ↗

Nah, for ≥11 spaces we should fan out to a GPT-6 Astra agent. On light reasoning of course, lest we be wasteful.

1h agoHN ↗

im so confused about what i should bring up at the 10am today

1h agoHN ↗

I have to be honest. While this is obviously a smart and useful idea, it misses one of the core features of Jev: its confidence scores. Partial confidence could easily be mapped to fractional spaces, using unicode characters like U+2009: THIN SPACE. As it stands, this package is not harnessing the full power of Jev.

50m agoHN ↗

its confidence scores

important to note that the "confidence" score is... maybe not what people think it is - kind of useless, and just a convenience step from the probabilities.

from the docs: "confidence is a statistic computed from the probability distribution the answer already gives you." [0] I actually encourage people to visit the docs because it has a specific page on this with a little applet to really make this clear.

[0] https://docs.typesafe.ai/confidence

1h agoHN ↗

wait.. is it just me or are we going overboard? I am waiting for jev assistance to exit vim, no wait.. a decision if we should exit vim or not.

54m agoHN ↗

You need to get the Pro version, please contact sales.

Flaky tests by design is a diabolical idea

1h agoHN ↗

This needs an SBOM and a SonarQube Qualitygate pass to be considered production grade code

How did this guy get a single-letter GitHub username?

1h agoHN ↗

i maintained a system where for .. reasons (like other systems) from early days have users with id: null "null" "" and some i do not even know how to write here

so probably early bird

1h agoHN ↗

His oldest repository was updated in 2011. Looks like he's been there a long time.

1h agoHN ↗

Jev mania at its peak? HN is full of Jev like today.

1h agoHN ↗

Instead of using Choice with criteria "space_0", "space_1"..., it could be even more elegant to use criteria names like "", " "... which could be directly inserted into response.

github.com/f is more impressive to me than jev-leftpad lol

I’d be curious to see how reliable it is in practice, it sounds like a cheap and (hopefully) easy benchmark
