You and your wife drop your 6-year-old off at school. You just moved here. You see ICE terrorizing your new neighbors. You film them, as is your legal right. Your wife complies with orders. She is then shot in the head. You still have to pick up your child later today. This could be you.

Intuition is all you need. Math is the language of the universe. We made it feel terrifying. It doesn't have to be. Made a thing 💜 unmath.ai Share with someone who was tricked into thinking math wasn't for them!

It’s a dark night when you look at the news and are forced to admit that you no longer believe in the power of the FIFA peace prize

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

Blogged: Creating a .NET CLR profiler using C# and NativeAOT with Silhouette andrewlock.net/creating-a-d... In this post I look at how to create a simple .NET profiler. But instead of using C++, the profiler uses C# and NativeAOT with @kevingosse.net's Silhouette library #dotnet

Did you know? You can run csc -langversion:? to see what language versions your C# compiler supports

Last week I did not manage to record any video, so here is second one this week. A tip on attaching debugger to the process you've just started, and easy way to re-attach to such process. One of my favorite overlooked features of VisualStudio. youtu.be/Tcz0cOHG_Zc #dotnet

I think pkgstore.io deserves some love! I think it's a fantastic initiative, and this could really be a great thing for the .NET community.

Found Sokol.NET - C# bindings for the Sokol crossplat gfx framework. If you haven't heard about Sokol, it's a C header-only library to build crossplat gfx/audio apps (games). Sokol.NET wraps it for C# (Win/Linux/Mac/Android/iOS/WASM). Tons of samples. Also native AOT: github.com/elix22/Sokol...

Ordered my third keyboard from CloudNine: cloudnineergo.com/products/clo... It's split/ergonomic, has mechanical switches and the classical IBM layout (arrow keys + Ins/Del/Home/End/PgUp/PgDn) that is so hard to find. Thinking of ordering a few more in case they stop making it.

I think this is actually "Everyone at Microsoft Hates AI," and given what I've witnessed in the past happening when Microsoft leadership decides they need to turn the aircraft carrier on a dime, I'm not at all surprised. There tends to be a LOT of collateral damage while they figure things out.

MSBuild tip: if you're working with binlogs, set the environment variable MSBuildLogPropertyTracking=15. It enables logging of where each property was initially assigned from during evaluation and lights up more features in the binlog viewer.

Years ago I complained about Windows creating 39+ page-zeroing pages on 96-core machines, which made memory zeroing much slower. The vast majority of the CPU time was consumed by fighting over a lock. randomascii.wordpress.com/2022/07/11/s...

Ever wanted to write `((a, b)) =>` to deconstruct lambda parameters in C#? I've created a proposal and am co-championing the feature now. Discussion: github.com/dotnet/cshar... Proposal: github.com/dotnet/cshar...

s&box going open-source was not in my bingo cards but here it is. I think they’re cooking something incredible, and the C# support is top notch and doesn’t feel slapped onto something else like a few other engines. sbox.game/news/update-...

This doesn't add as much clarity as I hoped it would:

Trying to measure coding productivity is, and always will be, a fool's errand. Why? Because I can go for a walk then take a shower and have an idea, then write a single line of code that fixes everything I was working on. Immense productivity, but by most metrics I didn't do anything at all.

One thing I started noticing recently is that competent engineers give up their credibility due to AI. Twice already highly competent engineers I respect sent a PR that turned out to have very subtle issues. These issues would not be possible if a human understood it.

In Odesa, a man's watch broke. He sees a store with the clock sign, walks in, says my watch is broken. The store owner: but we don't repair watches. Man: what do you do? Store owner: circumcision Man: but why is there a clock sign? Store owner: what would you like me to hang up there instead?

“In my work with the (Nuremberg Trial) defendants, I was searching for the nature of evil, and I now think I have come close to defining it. A lack of empathy... a genuine incapacity to feel with their fellow men. Evil, I think, is the absence of empathy.” - Captain G.M. Gilbert, US Army
