Hey y'all! My direct team, Product Service Services at @github.com is looking for a senior security engineer. www.github.careers/careers-home...

Our new #ILSpy version 11.2 comes with major performance improvements for agent loops github.com/icsharpcode/...

One week later, Pele is already in dozens of apps including Obsidian 1.15! Many improvements this week: - Even faster rendering! - Math resolver support: KaTeX, MathJax, Temml, etc - Gradients in sankey diagrams - Fewer edge crossings in diagrams with subgraphs - Sub, sup and inline code in labels

a critical PHP vulnerability may take websites down today. Admins are preparing for emergency patches, with estimates suggesting that more than 1.3 million internet-connected hosts are likely affected www.theverge.com/tech/1015257...

This is Pele, my new rendering library for diagrams and charts, compatible with the latest Mermaid syntax. - 100-500× faster than mermaid.js - 6× smaller bundle - No dependencies - Easy to theme - Responsive to device width - Open source (MIT) Try it at pele.run

Pele is a fast, beautiful, open source renderer for Mermaid diagrams we created for the next version of Obsidian. You can already try it in the Pele playground and integrate it into your own apps! 🌋 pele.run

Reverse engineering some old programs with claude is absolutely wild.

⚡ 3x faster .NET restore on GitHub Actions Windows runners, with two environment variables. By default, the NuGet cache sits on the slow C: disk. Move NUGET_PACKAGES and NUGET_HTTP_CACHE_PATH to the faster D: disk, and Windows restore times match Linux: awakecoding.com/posts/speedi...

Would you rather use a Windows App clone, or an mstsc clone? Assume it has 100% feature parity with the original

This sounds really interesting. Debugging in WinDbg isn't easy because you need to understand the fundamental concepts. I can imagine this is a great way to learn Windows internals and WinDbg.

Obsidian 1.14 is now available with five major improvements: 1. Edit Markdown files outside your vault 2. Preview files using macOS Quick Look when the app is closed 3. Instantly add notes with Quick Capture on iOS 4. Kanban and new grouping options in Bases 5. Highlight colors

The Azure policy 'Configure Microsoft Defender CSPM plan' doesn't offer options to configure 'API Security posture management' and 'Serverless protection'. I opened a Microsoft support case so the Azure Policy team can address this. I'll post updates as they come.

I suppose I should explain. Credential Manager, aka CredMan, aka cmdkey, is this thing.

I use a Pixel Watch and the new Google Health app. They work fine, but I was missing a few features. I have a Claude subscription this month, so I used it to build this: github.com/patrickmatul... It was fun to make and it helps me with some metrics I want to see.

I know.. I'm a bit late.. but it's a very interesting presentation about how Microsoft is looking forward to Rust and using it already in several code pieces.

It's nice to see so many Sysinternals releases and improvements! :-)

That’s awesome, plus $4 is super cheap for everyone else anyway.

About a month after the last 10.x servicing release comes #ILSpy 11. Ported to @avaloniaui.net, now available for Linux, Mac and Windows! THE open-source #dotnet decompiler just got ways more useful, read about the three major areas of investment at github.com/icsharpcode/...

Progress Telerik has confirmed that their new license forbids ALL Commercial usage of Fiddler "Classic" for Windows, even if you pay them. I have thoughts. textslashplain.com/2026/08/05/f...

It is honestly impressive how consistently HP's software developers are unable to close process handles when they are done with them. If you have a handle to the process and then the process dies then some of the metadata about the process is forced to be retained until you close the handle.

I dunno who needs to hear this, but if you hold ALT when double clicking a file in file explorer, it will open Properties for that file

📣 OpenAI just reduced the price of GPT-5.6 Luna by 80% and GPT-5.6 Terra by 20%. Try both models in VS Code today. Happy coding! 💙

Okay so now that we shipped stacked PRs, what's the next biggest request you have for GitHub to take on?

Process Explorer and Handle are excellent tools to manage that. Mark will also explain why renaming a file helps in specific situations. #sysinternals
