I wonder if the PR that introduced this masterpiece was also reviewed automatically

@PlusEVAnalytics @Apostate1123 Thoughts?

@Apostate1123 Parlayed with under? Nobody will let you do that.

Canada will be the nominal "home team" and bat last tomorrow vs USA as a +600 or so dog. If you can find a book with market-average prices on CAN and under that will give you a full-pay parlay (not rip-off SGP pricing), it's the most +ev bet you'll make all baseball season.

Tax season is here and filing may look a little different this year. From everyday investors to those with digital assets or capital gains, reporting expectations continue to evolve. I’ll be joining @Taxfyle for a live conversation on the 2025 filing season, what to keep in mind as we head into 2026, and how Robinhood Concierge works alongside Taxfyle to support eligible clients. Appreciate the partnership with @LavinaRicky and the Taxfyle team. 🗓️ Monday, March 9th at 11AM PT We’ll cover key updates, common filing mistakes, and how Robinhood Concierge and Taxfyle support a smoother filing experience.

@CarOnPolymarket @kaybest__ Polymarket is worse because of UMA, the whales resolve to whatever they want.

@kaybest__ Nope. Polymarket uses UMA to prevent stuff like this. Polymarket is 100% decentralized

Yesterday I lost $300 on my first bet ever on Kalshi. And I got scammed. And I should have won. So I immediately withdrew all my money from the site and blocked it. I was betting on the Bernie Sanders mention market. I bet on a few words he said during the live event. Most of the words were trading at 90%, but Kalshi resolved EVERY SINGLE word to NO. Why? I don' t know. The event was live, Bernie said the words and traders bought Yes. Kalshi has not said a single word since. 24 hours later I still don't know why I lost. I hear Bernie clearly say the words I bet on. A total of $3M+ was wagered on this event, people lost millions against reality. Why is Kalshi doing these sketchy things?

Javier Baez isn't playing for Puerto Rico in the World Baseball Classic because he tested positive for cannabis during the 2023 WBC, per @EvanPetzold

@MelkeyDev Imagine still using pandas when polars exists

I watched this video and it's actually odd. Like genuinely - he did zero google searches, and zero referencing of documentation for the libs he used (numpy, pandas, etc). He just kept typing, endlessly/never faced compilation bugs or errors. IDK. Seemed weird.

@trader_53 Similar thing with the official TikTok sale announcement before Dec 31 that didn’t happen (internal memo is not official, but resolved to yes anyway).

Gamblers, trying to collect their payout from Polymarket, left baffled as they learn that the US operation carried out in Venzuela does not meet Polymarket's definition of an invasion - Marketwatch

@bcherny Oh wow, thanks! I had searched the Claude Code and MCP docs (even had CC try to figure it out lol), is this documented anywhere? Also, great work on Claude Code! 🙌

@Jeffijoe Remember to mark your tool as read-only, so Claude knows it’s safe to run concurrently. server.tool( 'myTool', 'Description of my tool', { /* input schema */ }, { readOnlyHint: true, // <-- This enables concurrent execution }, handler, )

When I created Claude Code as a side project back in September 2024, I had no idea it would grow to be what it is today. It is humbling to see how Claude Code has become a core dev tool for so many engineers, how enthusiastic the community is, and how people are using it for all sorts of things from coding, to devops, to research, to non-technical use cases. This technology is alien and magical, and it makes it so much easier for people to build and create. Increasingly, code is no longer the bottleneck. A year ago, Claude struggled to generate bash commands without escaping issues. It worked for seconds or minutes at a time. We saw early signs that it may become broadly useful for coding one day. Fast forward to today. In the last thirty days, I landed 259 PRs -- 497 commits, 40k lines added, 38k lines removed. Every single line was written by Claude Code + Opus 4.5. Claude consistently runs for minutes, hours, and days at a time (using Stop hooks). Software engineering is changing, and we are entering a new period in coding history. And we're still just getting started..

@capjack2000 @MasterClass Definitely a nice intro, went through it in one sitting - another great (free) one is @goldenpants013 's YouTube course, highly recommend that one for anyone getting started as well!

I missed the 1yr anniversary of the sports betting @MasterClass that I was able to be a part of. I still think it’s a great Intro to Sports Betting that hopefully has helped steer new bettors in the right direction. Plus it produced the best ad mistake of all time ⤵️

@ChShersh @barelyreaper I've done something similar with Parquet files - lift the most important fields you need to query for into columns, Parquet files store min/max/other stats per row group which makes querying them pretty efficient. Using @DataPolars for querying; feels illegal how fast Polars is.

Answering, 1. Structured data. Think of binary encoded records. But each record could be different (~30 kinds of records) 2. Should be possible, as long as you can calculate the offset properly. 3. Patterns could be different but usually it’s something like “give me all records that have this field with this value”

Here’s a real task from my job. I have a 100GB binary file. Produced daily. I can’t grep it. But I can decode it. However, I can’t store the decoded version either. It’s too big. How do I efficiently query it? Decoding piped to grep takes 2 minutes. I want 2 seconds.

@tobiaslins The inline await imports are interesting - these things are trained on tons of code, of all things how did THAT end up being the most likely next token sequence? 😂

I'm slowly giving up on coding agents for certain things. - Code quality overall mostly bad - It loves to do inline `await import` - It often duplicates code that already exists At the end I'm spending more time babysitting with worse output

@kar_elnemr @ThePrimeagen This seems to be true in general. You never get the "hey great work on that service that hasn't gone down once in the past 3 years" appreciation poast, only the "thanks for working around the clock to get us back in operation after your sloppy code crapped out again" ones.

@ThePrimeagen Owning the issue publicly and outlining concrete steps builds real trust. Transparency like this turns a setback into credibility capital. I believe users remember how you handle problems more than the problems themselves.

how did you ever ship this without local control? i have to understand how, as the leader, you said ok to this in the first place?

@devongovett This was peak design, love to see this!

Having a blast re-designing all the React Aria examples this week. Flat design is so over – bring back depth! 😃

Something I've started doing lately is moving all of my styles to the root element. This keeps all of the styling in one place, and keeps the rest of my code super clean ✨ 😏

@marcospereeira @theo This was the last nail in the coffin that made us abandon Vite in favor of Rsbuild (based on Rspack). I wanted decorators, hot reload, and typescript parameter properties, and with Vite I had to choose 2. Rsbuild let me have it all, with better performance to boot!

@theo using a different build tool for dev vs prod is a bit of a downside personally I don't even use dev servers, I run the production build logic locally can't trust those js bundlers and minifiers

Vite is one of few “pure wins” we’ve ever had in the web space. It makes things better in many ways and worse in none. Excited to see what they cook with Vite+

@Reddy2399 @devongovett Base UI doesn’t seem to cover as many components as React Aria does though. React Aria is also used by Adobe, not sure how much more real-world you want.

@devongovett yeah, aria's alright but base ui feels way more intuitive for real-world apps. less boilerplate too

Very happy to see a mention of React Aria in shadcn/ui! 😲

@devongovett I noticed the dialog bottom was closer to the url indicator the second time you opened the dialog than the first time, is that another quirk? 🤔

I think I finally found a solution to reliably prevent scrolling behind modals on iOS! 😲 Works when tapping inputs, with different keyboard sizes, when the address bar is collapsed or expanded, programmatic focus, dialog scroll animations, etc. Coming soon to React Aria! 🎉

@tobias_petry Nice work! I was wondering, do you have any thoughts on DuckDB? It seems to be built for this kind of thing.

🚀 For the past months I worked on a FREE course to teach you how to make analytics queries fast. The truth is, that MySQL and PostgreSQL have terrible performance for statistic calculations in e.g. dashboards. 👇 Link in 2nd post
