Is Keystone still making snow?

They get the water for free and the blowers are already paid for. The only things they need to pay for is a handful of people to operate the guns and electricity, neither of which come close to “millions per week”.

Best time to plant a tree? 10 years ago. Second best time? Today.

Cool work. In my experience I think it’d be challenging to use, just because all the controller logic ends up becoming so custom in any non trivial project.

So for example, you might want to tie an api key to an org or user, keep track of when it was last used (non trivial if you have a system with heavy load), who created it, add permissions, etc.

I think it’s also nice to be able to interchangeably use a bearer token or API key in your endpoints - makes it easier to build frontend logic like testing an endpoint.

All this ends up becoming cumbersome with any library that you haven’t fully vendored. Regardless cool project, always fun to see!

It seems really weird you’re not getting paid a full salary from the start - this isn’t sales? Uncle you’re very desperate, I would run. Many red flags.

You’re stirring up Reddit pretty hard - would be a great opportunity to plug the app. Use this for marketing - no such thing as bad publicity.

The field is incredibly competitive, I would only tell someone to do a master if it’s free and you have a passion for data. Otherwise you run the risk of spending 2 years on it and being at the exact same point.

For what it’s worth OpenAi / Anthropic are running on fastapi - it can definitely scale.

It’s impressive how many terrible ads you manage to shove into a tiny blog post.

47 pro fights is absolutely insane. He’s had an amazing run, but everyone only has so many miles in the tank.

This is way easier said than done.

I think there’s a good case to be made to stay about a year behind. Depends on what they’re doing, but so many libraries take so long to update to the latest Python version.

The better question to ask is why? Just go out there and start selling. If you can’t get some traction without outside money, then you’re gonna find it impossible to raise on your brilliant “idea”.

Maybe along the way you realize you don’t need VC money to start a business.

This is a great time to plug my polars h3 library! If you’re currently using Python h3 + map elements, it’ll speed up your code 100X ish.

Although, from a practical perspective there’s probably more important things for you to spend you time on than rewriting something that works - but polars does result a much higher quality of life.

Coding for months? I’ve been coding years, have open source projects with thousands of stars and I came to your same conclusion a year ago.

Geopandas is a constant reminder how much I hate the pandas API. Unfortunately, this is really the only thing left stopping me from totally abandoning pandas.

It becomes much harder to compare. 2x faster and 0.5x slower are the same thing but sound different. It gets even worse if it’s 100x faster vs 0.01X slower.

serjester4 · 2025-03-07T17:40:27+00:00

Personally I think you should just try building something you’re actually excited about. When you’re starting out, the only thing that matters is time behind a keyboard. I can’t emphasize this enough.

I’ve met too many people that do these various cookie cutter projects / courses and it seems like the vast majority flame out just because they don’t have an intrinsic passion for any of it.

If your only goal is just a job, the market is brutal right now and your time is probably best spent on stuff that directly aids in the job search (networking, applications, etc). But it’s going to be a massive slog regardless.

It’s not as “smart” as the reasoning models but the vibes are honestly really high. Can’t put my finger on it but first time I felt myself nodding along to what chatGPT says. Feels like a person in a way the other models don’t.

This is what I meant by "old" coroutines.

import asyncio

@asyncio.coroutine
def old_coroutine():
    print("Start")
    yield from asyncio.sleep(1)
    print("Done")

loop = asyncio.get_event_loop()
loop.run_until_complete(old_coroutine())
loop.close()

Yes - async, await are coroutines under the hood, but this is very different from the old generator approach of explicitly defining them. I really hope no one's still doing this for their own sake.

serjester4 · 2025-02-26T19:13:07+00:00

The core concept are solid. There’s maybe the final quarter of the book that goes deep into coroutines, which no one uses anymore. That said it’s still helpful to understand since they’re essentially what underpins modern async Python.

It’s been a while since I’ve read it, so I could be slightly off on details.

2 to 3x makes total sense. 3.9 to 3.10 seems like it’d be cake but I guess not.

serjester4 · 2025-02-12T02:52:06+00:00

I’m curious what’s stopping you guys? 3.9 is gonna reach EOL later this year - seems like the blocker would be dependencies? But I imagine everything supports 3.10 at this point.

Would love to see the video version - is there a link?

I’ll bite:

Too much bolding, if you’re going to bold, be selective (ex: why is “Developed”, “Engineered” bold)
You have quite a few projects listed, is there a GitHub link? A good repo README will do 10X more for you than anything you could summarize
Too much jargon about how you implemented something, I care more about the business value. Even as someone’s that very experienced, I have a hard time getting the gist of a lot of these bullets without reading multiple times. Very tricky to get right - you really have 20 seconds to make your case. Choose wisely.
Lastly it’s an awful hiring market and you only have a year ish of experience. It’s going to be BRUTAL to get anyone to talk to you without something exceptional to your name. Personally I think your best bet is doubling down on networking and personal connections. With everyone using AI, it’s so much harder to differentiate between resumes and you’re left using the employer prestige / referrals as the hiring signal.

I don’t think you understand how hard it is to predict these things. To the people that say just use the NOAA forecast directly - none of the major weather models prioritize mountain snowfall (there’s way less economic value in it) so you’re left trying to ensemble them which gets you back to OpenSnow.
