casey··on Ask HN: Who is hiring? (May 2024)
Y Combinator | Software Engineer | San Francisco, CA | ONSITE | Full-time

You're reading HN, why not come build software at Y Combinator itself! We are a small independent team of experienced engineers who try to make being funded by YC a great experience for founders. If the idea of designing software to help startups and the YC group partners sounds interesting to you, please reach out!

We work in Ruby on Rails, with a React/Typescript frontend. We move quickly and autonomously, and while we're not exactly doing rocket science (although we fund it), we're always experimenting with ways to make the YC batch better.

YC has excellent compensation and benefits (see more in the formal job description below). The team and the work life balance are great. About half of us are former founders and many of us are parents. And if you’re curious about startups (and possibly starting one someday), this job gives you amazing access to interact with YC’s programs, partners, and founders.

Please drop me a line if you're interested: casey@ycombinator.com

casey··on An app for M1 Macs that plays the sound of a fan as CPU usage goes up
This is awesome! I built a similar open source version a few years ago for a friend with a fanless Air, but it foolishly used system notifications and a menu bar icon instead of sound:

casey··on Native Mac APIs for Go
This is great, I've done a few one-off go wrappers of objective C libraries [1][2] for an OSX menuapp framework I built [3].

This seems like a much more general and useful solution, excited to switch some things over to it!

casey··on Shipping a Neural Network on iOS with CoreML, PyTorch, and React Native
I love the description of convolutions:

> I think of convolution as code reuse for neural networks. A typical fully-connected layer has no concept of space and time. By using convolutions, you’re telling the neural network it can reuse what it learned across certain dimensions.

The diagram is great too: https://attardi.org/pytorch-and-coreml#convolution

I believe this is what the author tried first in the post. He even links to this test UI where you can compare the "plain math" approach to the neural network:

@steadicat I love this part:

That's just where we put the ajax paths to keep a cleaner URL space
casey··on Airbnb Tech Talk: Evan Priestley of Facebook - Move Fast and Break Things
Evan is hilarious, check out all the copy on http://phabricator.org/ for an example.

However he should probably have been described as ex-Facebook, he left quite a while ago.

casey··on Facebook deleted their Python SDK repository without warning
Sorry I couldn't help more, internally a lot of us were surprised by this move also.
casey··on Show HN: Who's Hiring? (postings mined from Twitter)
Nice. You need to linkify the tweets so users don't need to copy and paste the URLs to the actual job posts.

Too bad they were looking at his page: http://www.facebook.com/markzuckerberg

Not his profile: http://www.facebook.com/zuck

Cool, I was curious also: http://www.spothistory.com/

Looks like I need to add datacenter, and you need to add OS :-)
