Hey traders and prediction market nerds—I've been deep in @Polymarket and @Kalshi for months, watching whales drop $100k+ bets on everything from BTC pumps to Super Bowl odds, but the raw data was chaos. No one was surfacing the skilled players and their moves in real time. So I built 0xinsider.com: a live terminal streaming every big trade across those platforms. See graded wallets (S-tier with 73% win rates, +12% edges), reconstructed positions, ML-spotted strategies like "Accumulator," leaderboards by Sharpe not just P&L, and anomaly radar for insider vibes.​ Your second monitor deserves this, not headlines. Free tier to start, 7-day money-back on paid.

@Polymarket 35% and climbing fast. wonder how many portfolios are still positioned for the multiple rate cuts everyone expected 3 months ago

BREAKING: The odds of no rate cuts this year soar to 35%

@PolymarketSport 1.8% with 6 minutes left. this is why prediction markets during live sports hit different. no sportsbook would have given you those odds

🚨MADNESS: VCU had a 1.8% chance to win with 6 minutes left vs North Carolina... They made a 19-point comeback and won in OT $300 on TCU would have cashed $15,000.00 on Polymarket

@thdxr the best endorsement for any model is forgetting you switched. that's the bar now, just be invisible and good

everyone's probably tired of how many models are available nowadays but i still have to say i've been using mimo-v2-pro all day and i completely forgot i was trying something new it's free right now in opencode if you want to try

@Barchart longest period below the 200 day since 2022 and nobody seems to be panicking about it. either the market is pricing in a recovery or META holders just have higher pain tolerance than I expected

$META has traded below its 200-day moving average since Halloween (except for just 5 days), the longest such period of weakness since 2022 🚨🚨

@shadcn chart color presets. small detail but this is the stuff that makes the difference between looking like every other dashboard and actually having a design identity

Two updates to presets. Font Heading lets you set a custom heading font. Chart Color lets you set a different color palette for your charts. More customization. One preset code.

@kentcdodds What are you building on it? Workers + D1 or the full stack?

The Cloudflare platform is enabling me to quickly build things I wanted to before but I didn't because it was too much work before.

@signulll Discovery and document review seems like the obvious first service. I'm more curious who the first client willing to trust it will be

i know everyone is building ai software but is there anyone opening up an ai native law firm? like built from the ground up, every service, every area is a person or two empowered by custom built software.

@PolymarketSport 16% swing in a first half. that's the kind of live repricing you can't get anywhere else. Peterson's window is closing fast if Dybantsa keeps performing like this

🚨BREAKING: AJ Dybantsa's odds to get drafted 1st overall shot up 16% during the first half of BYU vs Texas. AJ Dybantsa - 72% Darryn Peterson - 24%

@ellie_huxtable postgresql index governance is a topic near and dear to my heart at this point

@trevorlasn one of the few that got the full thing 👏

spot the error from a younger, dumber me

@pcshipp 198 signups and $9 MRR means people want to try it but not pay for it. the only question that matters right now is why

How do people make $10K MRR or even $100K MRR while I’m still stuck at $9 MRR? - $9 MRR - $2 revenue - 198 New users - 206 Active users No idea how to start marketing

@KobeissiLetter 228% in 3 years is exactly the kind of growth that looks like demand until it doesn't. curious whether utilization rates on existing data centers support this pace

BREAKING: The value of US data centers under construction has officially surpassed the value of office buildings under construction for the first time in history. Data centers under construction are up+29% YoY, to a record $45.1 billion. Meanwhile, the value of offices under construction are down -13%, to $43.5 billion, the lowest since October 2015. Since November 2022, when ChatGPT was launched, data center construction is up +228%. Over that same period, office construction is down -38%. AI is reshaping the US economy.

@melvynx Have you looked at the test setup? 34% failure rate is extremely unusual for Next.js in production. I've been shipping with 16 for months and my bottlenecks have always been database and external APIs, never the framework

This graph is quite insane. TanStack Start is: • 1.5 to 2 times faster than Next.js • Next.js actually fails 34% of requests for... nothing What is this? Wtf?

@mil0theminer the users who do this were never going to pay anyway. at some point you just accept that and optimize the free tier for word of mouth instead

If you give me a free plan and I run out of credits, I’m not giving you money, I’m making another account for more free credits

@_dylanga @tryramp @modal the self-triage loop where it reviews its own dashboard and creates PRs is the most interesting part. most teams never close that loop. how reliable has it been at actually fixing the right things?

The first thing I did at @tryramp was set up distributed tracing, structured logging, and metrics for Inspect, our background coding agent. We now have full visibility in to everything the system is doing: the browser, CF workers/DOs, @modal sandboxes, database calls, etc. Most importantly, Inspect now has visibility in to itself. It can self-triage runtime errors it encounters and create PRs to fix them. Every morning, it reviews the past 24 hours of its own @datadoghq dashboard, identifies systemic issues, new errors, and long tail latencies, and has a summary + PR waiting for me at 9am.

@shawn_pana that's clean. OAuth is where agent auth usually gets messy, that coming too?

@trevorlasn aurl handles all authentication. `aurl auth` saves API keys and other authentication methods (soon) run `aurl auth` once, reuse the service whenever you want

I've stopped downloading CLI tools. Agents can call APIs directly. aurl allows agents to understand and use APIs. > curl for humans → aurl for agents > API docs as --help flags and SKILL[.]md files pass in an API spec, agent instantly learns new tools

@OttoSuwen a prediction market bar in DC. I give it 6 months before they add a market on whether the bar itself survives

Kalshi in a few days

@wustep bold h3 veterans deserve a migration path

we didn’t think it was possible after multiple years of R&D, the technology is finally here

@shawn_pana Thanks for sharing this, Shawn
