brianyu8··on Six-year-old breaks women's world Rubik's Cube record [video]
or, something is very cool when someone unexpected excels at something :)
brianyu8··on Claude Code gets native LSP support
I am super bullish on claude code / codex cli + LSP and other deterministic codemod and code intelligence tools.

I was playing around with codex this weekend and honestly having a great time (my opinion of it has 180'd since gpt-5.2(-codex) came out) but I was getting annoyed at it because it kept missing references when I asked it to rename or move symbols. So I built a skill that teaches it to use rope for mechanical python codebase refactors: https://github.com/brian-yu/python-rope-refactor

Been pretty happy with it so far!

brianyu8··on Structured outputs on the Claude Developer Platform
Brian on the OpenAI API team here. I would love to help you get to the bottom of the structured outputs issues you're seeing. Mind sending me some more details about your schema / prompt or any request IDs you might have to by[at]openai.com?
brianyu8··on Lesser known parts of Python standard library
If you liked this blog post, I can’t recommend PyMOTW[0] highly enough. It’s my goto for a concise introduction whenever I need to pick up a new Python stdlib module.

brianyu8··on Finding near-duplicates with Jaccard similarity and MinHash
This visualization is super cool! Thanks for sharing.

brianyu8··on US Department of Energy: Fusion Ignition Achieved
What an amazing achievement. I was curious, so I looked up the open software roles at LLNL[0]. I'm very curious how the salary compares to your average bay area tech salary.

brianyu8··on Man of the Hole
Fascinating article, thank you for sharing.

I found it incredible how several of the siblings are now well-known artists[0]! What a life these people have led.

brianyu8··on Why a 224-Year-Old Human Heart Is Touring Brazil
> the 20-pound heart seems to be in good shape for its age. Still, there’s something about it—its pale color and gigantic proportions—that make it seem unreal. According to Da Silva, this dilation was probably caused by tuberculosis, which can cause the swelling of some organs.

Apparently a normal human heart weights 10 ounces[0]. That means Dom Pedro's heart is 32x the weight of a normal heart! Can all that extra weight truly be caused by tuberculosis alone?

brianyu8··on Stripe acquires Nigeria’s Paystack for $200M+
You're right about that -- Stripe led Paystack's series A and has also led other series A rounds like Fast's.
brianyu8··on PG and Jessica
In a similar vein, "You Are Not Late"[0] by Kevin Kelly is a great read.

brianyu8··on Show HN: HN Demetricator – An extension that removes upvote and comment counts
That's a really interesting premise! I'm going to keep an eye on sqwok.
brianyu8··on Show HN: HN Demetricator – An extension that removes upvote and comment counts
It's true that upvote count and comment counts are the best way we have to quantify the quality of a submission. That's why I still browse the top posts page and will still upvote a post that I think is high quality.

But for me, upvote and comment counts bias my perception of a post. I'm choosing to hide these counts so I can read articles uninfluenced by the number of points they have relative to other posts on the front page.

brianyu8··on Show HN: HN Demetricator – An extension that removes upvote and comment counts
For me, the problem was more that the highly upvoted posts were obviously good, so my time and attention were spent scrolling through HN looking for posts with more than ~50 upvotes or more than 10 comments.

After hiding upvote and comment counts, I've found myself reading more of those high-quality niche articles that I wouldn't have clicked on previously. I've also found myself reading post titles more thoroughly and reading articles first instead of immediately jumping into the comment section to get summary/judgement.

Perhaps this extension is unnecessary if you have more self control that I do ;).

brianyu8··on Ask HN: After Slate Star Codex, where are the nuanced discussions?
lobste.rs is a site similar to HN where users must be invited by another user and the public tree of invites is kept as a sort of reputation map. Might be similar to what you’re envisioning.
brianyu8··on Making Databases Work: The Pragmatic Wisdom of Michael Stonebraker (2018)
The respect and reverence you hold for your former colleagues is heartwarming. Thank you for sharing!
brianyu8··on Playing around with the Fuchsia operating system
Another data point: I was an intern at Google last year and they gave most of the interns Pixelbooks. It worked fine for development (granted, development consisted of SSHing into a dev box and using a web-based IDE).
brianyu8··on What Is Nix?
Post a link about it tomorrow and maybe your prediction will come true ;)
brianyu8··on Learning Rust in 2020
If you're looking for an equivalent for Rust, I've found Rust by Example[1] to be an excellent resource.

brianyu8··on The Day I Found Out My Life Was Hanging by a Thread (2017)
This story is in the same vein as that of the CloudFlare cofounder[1] who suffers from a rare neurodegenerative disease and has had his life pretty much taken from him at far too young an age.

This quote in particular gnaws at me: "We had promised each other that in a few years, when the girls headed off to college, we’d work less and travel more. Amy didn’t deserve to lose those dreams, or her companion, just as we were on the brink." I, presumably like many others here, have spent a lot of time on my career, perhaps to the detriment of other aspects of my life. Is it worth it? That seems like an impossible question to answer.

brianyu8··on What you need to know about the Covid-19 vaccine
This resource[1] linked by Gates in the article says

> "Most of the active projects are in exploratory or preclinical stages. However, 5 candidates have recently moved into clinical development, including mRNA-1273 (Moderna), Ad5-nCoV (CanSino Biologicals), INO-4800 (Inovio), LV-SMENP-DC and pathogen-specific aAPC (Shenzhen Geno-Immune Medical Institute). Notably, Moderna was able to start clinical testing of its mRNA-based vaccine just 63 days after sequence identification."

Presumably, those are 5 out of the 8-10 that Gates thinks is promising

brianyu8··on Frank Ramsey – The Man Who Thought Too Fast
Makes me think of Ramunjan. It's quite tragic to think about how much more knowledge humanity would have if these two lived a little longer.
brianyu8··on Which is better on Android: divide by 2 or shift by 1?
While I think that there is merit to your argument, I feel like it could have been presented without questioning the author's intelligence or mental state.
brianyu8··on Hands-on Scala Programming
I've been wanting to learn more Scala and this book seems perfect! I'm definitely going to buy it when it comes out. The website mentions that there's a PDF download of the free chapters, but I can't seem to actually find it. Do you have a direct link?
brianyu8··on Hands-on Scala Programming
I think the parent is just giving background about the author of the book, who wrote all of those tools mentioned. I don't think they're only trying to convince you that Scala is easy, but maybe I'm reading it incorrectly.
brianyu8··on Anton (Computer)
“The performance of a 512-node Anton machine is over 17,000 nanoseconds of simulated time per day for a protein-water system consisting of 23,558 atoms.[5] In comparison, MD codes running on general-purpose parallel computers with hundreds or thousands of processor cores achieve simulation rates of up to a few hundred nanoseconds per day on the same chemical system.”

17,000 ns of simulation per day sounds crazy small but I wonder how that compares to the timescale of molecular interactions. How helpful have Antons been to pharma research etc?

brianyu8··on Ask HN: What projects are you working on now?
A friend and I are home from college right now because of the virus. We just started working on HighlightKit (https://highlightkit.com/), which makes it incredibly easy to add Medium-esque text highlights to your own website/personal blog. Users can save their highlights, view top highlights from other users, and share highlights on Twitter. We're open to feedback and are looking for pilot users!
brianyu8··on Ask HN: What has your work taught you that other people don't realize?
'The Dream Machine' by M. Mitchell Waldrop chronicles the trials and tribulations of the people who built the first computers and computer networks. Great read if you want to learn more about how computing and the internet were started!
brianyu8··on The Cassowary: World’s most dangerous bird (2016)
In the WaPo article:

"In 2012, an Australian tourist named Dennis Ward was kicked off a cliff into a body of water by a cassowary when he and his family were visiting Babinda Boulders in Queensland. 'It just came straight up to me, decided to pick on me for some reason, I don’t know what for,' Ward told the Cairns Post."

I shouldn't be laughing but that is an outrageous story.
