joshuabaker2··on Apple M5 chip
You can convert a PyTorch model to an ONNX model that can use CoreML (or in some cases just convert it to a CoreML model directly)
joshuabaker2··on Show HN: Shoggoth Mini – A soft tentacle robot powered by GPT-4o and RL
I was surprised it pinged gpt-4o. I was expecting it to use something like https://github.com/apple/ml-fastvlm (obviously cost may have been a factor there), but I can see how the direction he chose would make it more capable of doing more complex behaviours in the future w.r.t adding additional tentacles for movement and so on.
joshuabaker2··on Claude 3.7 Sonnet and Claude Code
Hi Boris, love working with Claude! I do have a question—is there a plan to have Claude 3.5 Sonnet (or even 3.7!) made available on ca-central-1 for Amazon Bedrock anytime soon? My company is based in Canada and we deal with customer information that is required to stay within Canada, and the most recent model from Anthropic we have available to us is Claude 3.
joshuabaker2··on "Fake Chinese income" mortgages fuel Toronto real estate bubble: HSBC bank leaks
Mortgages in Canada are different than mortgages in the US in that they are full recourse. If the sale price during foreclosure doesn’t cover the costs, the banks can go after you personally for the balance. So you’d have to either a) leave the country, or b) declare bankruptcy. So, not exactly a risk-free option.
joshuabaker2··on "Fake Chinese income" mortgages fuel Toronto real estate bubble: HSBC bank leaks
Yes this is accurate. I work at a lender that operated in both Canada and the US and the credit bureau integrations were with totally different companies and had different APIs (even for Equifax on both sides of the border)
joshuabaker2··on "Fake Chinese income" mortgages fuel Toronto real estate bubble: HSBC bank leaks
Yes, but it’s partly the government’s fault. There’s literally no way for mortgage lenders to pull your tax records in order to verify income. There used to be some third party services to connect to the CRA but they got shut down and replaced with… nothing.
joshuabaker2··on Launch HN: OutSail (YC W23) – Wingsails to reduce cargo ship fuel consumption
Predictability, speed, cheap fuel, a lack of understanding of climate change, etc.

We also used to have windmills to grind grain and then switched over to mills that use electricity or fossil fuels. But of course, windmills to generate electricity have become quite popular. What's old can be new again when combined with modern technologies.

joshuabaker2··on Launch HN: OutSail (YC W23) – Wingsails to reduce cargo ship fuel consumption
I did! He's awesome. I was on the software side of things and he was the mechanical but our paths crossed quite frequently.
joshuabaker2··on Launch HN: OutSail (YC W23) – Wingsails to reduce cargo ship fuel consumption
This looks amazing! Wind power is totally underutilized in the shipping industry, I've been waiting for something like this for ages.

I used to be part of a team back in university making autonomous sailboats [1] and one of the things that I was surprised by when working on this was that there are a TON of hurricanes out in the middle of the ocean (we were working to build it to cross the Atlantic). We built a system to take in weather prediction data to try to avoid hurricanes, but we were building a relatively tiny boat—do large shipping vessels do this as well? I'd assume they can sail through pretty bad weather. If so, do you have ways to lower the sails easily to protect them?

Additionally, do you have any software to help inform the vessel operators how to best sail into the wind or are the net savings not worth it considering most of the propulsion is still coming from fuel-based sources?

Overall, this is super exciting and best of luck!

joshuabaker2··on Zed, the new code editor from Atom developers, has entered open beta
The first thing I always do when I go into any new editor is set up the "Select All Instances of highlighted word". So like how there is cmd-d for the next occurrence, I also like having a shortcut to select _all_ occurrences. Would love for this to be added.

More generally, this looks really awesome and also really enjoyed your team's blog post detailing the GPUI implementation (even though large parts of it went over my head)

joshuabaker2··on Launch HN: Second (YC W23) – AI bots that add features to web apps
This looks very cool, would love to see something like this take off - boilerplate code is such a hassle to stand up for each new project. Does this work with existing hand-made repos or is it mostly intended to work with projects that it generated?

I'm imagining it would be quite challenging to add in e.g. an auth system to an existing backend service and have it match the same coding paradigm as the rest of the app but maybe there'd be some way of annotating your code with comments to make it easier on this system to understand what it's looking at?

Suggestion: the PRs should be draft PRs, otherwise it'll probably be very noisy for teams.

Also, have you thought about doing any integrations with Replit? They are a yc company too and seem to be going all-in on AI and I think the bulk of their user-base is students and junior developers so there might be some synergy there.

joshuabaker2··on How Discord Stores Trillions of Messages
Solid article. Is it fair to say that the "data services" layer is essentially a cache sitting in front of the database, or am I misunderstanding it's function?
joshuabaker2··on Ask HN: Any successful stories of finding co-founders online?
I met one of my co-founders (we are now a Series A startup) originally via LinkedIn, and together we met our third co-founder also via LinkedIn. The first co-founder and I are in the same city, but the third one was in a different country - so it was almost a year later and many months after we'd raised our original seed round that we ever met the 3rd co-founder in person (we started during COVID lockdowns).

Overall it's been pretty good, the geographic diversity of our founding team gives us different perspectives on hiring and fundraising, and it means we had multiple "locations" right from the get-go.

joshuabaker2··on Ask HN: Who is hiring? (October 2021)
Fraction | Frontend, Backend Engineers and Full Stack Developers | Full-Time | Vancouver, BC or Berkeley, CA | Onsite, Hybrid, or 100% Remote (your preference)

Looking for a new engineering position but dreading leetcode-style questions? Having flashbacks thinking about re-reading Cracking the Coding Interview? Apply to Fraction! Our engineering interview process has been described as "surprisingly humane". There's no leetcode questions, no all-day onsite interview gauntlet.

What's the work like?

Fraction is building a number of new and exciting technically-challenging projects that you will be one of the first people to work on. Since the company is so young (launched in February 2021!), there's lots of completely new projects, only some maintaining of existing projects, and absolutely no legacy code. Upcoming projects that you might be the one kickstarting include:

- An event system for managing asynchronous workflows.

- A payments system to enable Fraction's customers to make and receive payments.

- A dashboard for customers to interact with our platform, and another dashboard for our internal operations team to automate their workflows.

Although our stack is all Typescript, if you are backend-focused, we don't require experience with it (if you are frontend, we do expect you'll have experience with React, as it is part of our take-home challenge and you'd be unlikely to complete it successfully without that experience).

Fraction is a Series A fintech company. We've come out with the first truly innovative mortgage/HELOC product in the last couple decades. This isn't just a spin on a better application process, it's genuinely a new product in a new category to enable people to access the equity in their homes. Along with the new product, we are building our systems from the ground up to enable a better, faster, and more transparent user experience.

You can apply on our website at https://www.fraction.com/careers, or you can drop me a note at josh [at] fraction.com

I noticed that too. Maybe it's related to the maintenance NPM is currently doing? https://status.npmjs.org/
