kevinqi··on Tesla has the highest fatal accident rate of all auto brands, study finds
ah interesting, that makes sense witas an explanation given the heavy Tesla base
kevinqi··on Tesla has the highest fatal accident rate of all auto brands, study finds
yeah I've had a similar experience with a bike and do the head bob thing now too. glad to know it's not just me
kevinqi··on Tesla has the highest fatal accident rate of all auto brands, study finds
good tip, thank you!

Aside from the distracted driving part, which is real, there are two physical aspects of the model 3 that I find to be safety issues as well-- the two front windshield beams are thick and add a sort of blind spot, and the side mirrors don't give you great field of view.

kevinqi··on Almost every infrastructure decision I endorse or regret
30-40 people; not much TPS but we're not primarily building a web app; we have event-driven data pipelines and microservices for ML data.

If you're primarily building a web app, a monolith is fine for quite a while, I think. But a lot of the stuff in the post is still relevant even for monoliths - RDS, Redis, ECR, terraform, pagerduty, monitoring/observability.

kevinqi··on Almost every infrastructure decision I endorse or regret
I work at a startup and most of the stuff in the article covers things we use and solve real world problems.

If you're looking for successful businesses, indie hackers like levelsio show you how far you can get with very simple architectures. But that's solo dev work - once you have a team and are dealing with larger-scale data, things like infrastructure as code, orchestration, and observability become important. Kubernetes may or may not be essential depending on what you're building; it seems good for AI companies, though.

kevinqi··on Apple dials back car's self-driving features and delays launch to 2028
"No" seems easy to say right now, but technology is accelerating at a breakneck pace. If AGI can happen within a decade, I reckon 2030 self driving is not a crazy bet at all.
kevinqi··on Lessons from 5 years of running a tech meetup
Loved the article! Really well written, thoughtful, and actionable advice.

Gridmatic | Senior full-stack software engineer | Onsite in Cupertino, CA (hybrid)

https://jobs.lever.co/gridmatic/ee0f4882-10aa-4c92-b0bb-1497...

Gridmatic is a profitable early-stage climate tech startup that uses ML forecasting to help decarbonize the energy grid. We use ML to help with grid-related operations like optimizing battery farms and being a retailer of 24/7 carbon-free energy.

We’re looking for an experienced full-stack engineer with 3+ YOE with the ability to build product from zero-to-one to work on our retail energy initiative. You’d work across the stack on a wide range of projects — building out a web app for energy customers, working with third-parties to pull in energy usage data and public renewable energy data, integrate billing and other key operational systems, and help improve automation and scale up to hundreds of customers. We value the ability to push through uncertainty and take ownership of the retail web platform.

Our stack is Python, React, Postgres, Kubernetes, and GCP. Having Python and React experience is preferable.

Gridmatic has a hybrid policy of "50% in-office”. Most of the company works in our Cupertino, CA office 2 or 3 days a week.

Apply here: https://jobs.lever.co/gridmatic/ee0f4882-10aa-4c92-b0bb-1497...

kevinqi··on My 40-liter backpack travel guide
Huh? Individual actions do matter. The fact that he got on these flights contributes to the overall demand on flights, and has certainly had an impact on how many flights need to exist. The argument that not all people can fly every 2 weeks is nonsensical.
kevinqi··on I/O 2022
damn. I've been hanging on to my 3a, unfortunate to hear.
kevinqi··on Controlling the nuclear fusion plasma in a tokamak with reinforcement learning
That's a great question; I'm curious about this as well.
kevinqi··on OpenAI Codex
"the bitter lesson" is a very interesting, thank you! However, I wonder if AST vs. text analysis is fully comparable to the examples given in the post. Applying human concepts for chess, go, image processing, etc. failed over statistical methods, but I don't think AST vs. text is exactly the same argument. IMO, using an AST is simply a more accurate representation of a program and doesn't necessarily imply an attempt to bring in human intuition/concepts.
kevinqi··on $100M xPrize for Carbon Removal
This seems easy to say, but how can small groups of people make actionable change on burning less fossil fuel? Will you protest outside coal plants? Cement plants? Steel plants? Stop flying in airplanes? Do you still use a car that burns gasoline? Will oil companies do the right thing and simply choose to make less money?

I agree that not using fossil fuels is the most efficient method, but it's also not easy to take action on. We need to pursue every viable avenue in parallel, and carbon removal solutions are, if not particularly efficient yet, at least very actionable. And with R&D, perhaps they will become more efficient.

kevinqi··on How People Get Rich Now
yeah having lived in both cities, I think the likelihood of success in the bay area is going to be higher than in boston for sure.
kevinqi··on Slack is down
Assuming this is real - very interesting read, thanks for sharing.
kevinqi··on Now dev – Serverless on localhost
How does Next.js compare to Gatsby?
kevinqi··on Ask HN: What're the best-designed things you've ever used?
Teenage Engineering OP-1, a music synthesizer. Really well built, buttons and knobs feel fantastic, and the display is super fun. The OP-1 in action: https://www.youtube.com/watch?v=umatbZ0n4mE
kevinqi··on IDE for building React Native apps is now free and open source
yeah, dragging components from the component list and seeing them immediately reflected in the simulator with live-reload is freaking awesome.
kevinqi··on You probably don't need a JavaScript framework
React calls itself "a JavaScript library for building user interfaces", which I think is accurate.
kevinqi··on Chart.js 2.0 Released
fwiw, I've liked https://github.com/danielgindi/Charts for iOS, which is based on an android charting library called MPAndroidChart.
kevinqi··on Postgres features and tips
oh! yeah I use \x only in situations when it wraps, so \x auto fits the bill.
kevinqi··on Postgres features and tips
As someone who always uses \x, having it become a default setting in .psqlrc is a useful one.

Awesome alternate angle: https://vine.co/v/iKPTghqF0LA
kevinqi··on SpaceX launch webcast: Orbcomm-2 Mission [video]
Yup, that's what I'm wondering too. How much variance is there from launch to launch, and to what degree is this reproducible?
kevinqi··on Grooveshark Shuts Down
As much as it must suck for Sam Tarantino & co., it must also be relieving in some measure - fighting such huge labels for so long must've been incredibly stressful.
kevinqi··on HackerSurfing: Free Housing and Food for Engineers Visiting SF
Looks sweet, but in the FAQ they say they can only host 2 people at a time.. given the amount of interest this seems to be getting, seems like it'll be tough to land a spot.
kevinqi··on Restart: Microsoft in the age of Satya Nadella
I don't know how much of it has been Nadella, but I've been impressed by everything I've heard about Microsoft the last few months - open sourcing .NET, adopting new platforms, this holographic tech and the free Windows 10 upgrade. If this is anything to go by, Nadella is going to do great things at MS.
