Beautiful. Some C# and .NET is super performant good news again. 🙏🏼️
C# FTW again github.com/devmobasa/ttfx Against Python up to 140x faster! Against Rust from 0.3.3 version that DHH referenced here up to 2.12x Since you don't like Rust, you can just port it to a much prettier language like C#, and no need to sacrifice performance. C# on Linux

C# and .NET being speedy and scaleable
C#/.NET being pushed hard running infrastructure at Ethereum's scale. Nethermind runs on ~3k nodes and accounts for ~33% of staked nodes - supporting a ~$334B native asset, ~$146B of stablecoins and ~$54B deposited in DeFi apps. Nethermind 2.0 has some amazing performance work
Microsoft should dogfood C# and .NET a lot more than they do.
Microsoft recently ported the GitHub Copilot runtime from TypeScript to Rust in roughly 4 months. The entire port was mostly guided by one single engineer and generated a token cost of around $120k. Here are few of my thoughts through my CTO lens. 1. Why Rust and not C#? With

First TypeScript compiler, now GitHub Copilot has been ported to Rust. I am getting MASSIVE vibes that Microsoft is not taking C# seriously. If C# isn't good enough, make it good enough!
Just one engineer and a team of agents ported the GitHub Copilot agent runtime to Rust, shipping 800,000 lines of production code while retaining code quality. 🚀 How it worked 👇 github.blog/ai-and-ml/gene…
@MrPeterLMorris @davidfowl @stephentoub It does make you feel this sometimes.
@AdamFrisby @davidfowl @stephentoub Do Microsoft actually have any production .net it’s all rust or typescript it seems?

Fable 5.1 and GPT-6 Astra and Daybreak Blue 🙏🏼️
Checking to see if I have GPT-6 Astra yet. Has anyone got access in the UK? (Ignoring those who had pre-announcement access.)
this!
fwiw, don't love that OpenAI "launches" aren't actually launches, and the real world availability date is an unknown amount of time down the line. We should all be able to play with this new model together right now, feels weird that only certain people have access.
8 days since an incident free day at Claude solrevdev.com/hasclaudehadag…
Microsoft Visual Interdev. It had syntax highlighting and intellisense which was magic at the time.
@RaoulGMI @AnthropicAI @claudeai 7 days since it had an incident free day solrevdev.com/hasclaudehadag…
Has Claude had a good day lately? No. So I built a site that answers exactly that question, with a live counter fed by status.claude.com's public API. The last fully incident-free day was 11 August. It's 7 days and counting. solrevdev.com/hasclaudehadag…
looks good ship it 💀️
@rickygervais My 20-year-old cat Kato wants to watch it again tonight.
@rickygervais Kato (20 yo) watched it with me last night. Enjoyed it. Great cast and animation. Excellent swearing.
@alexgreensh @daniel_mac8 Yes this looks great. Will test it out! 🙏🏼️
