Andrew Lock "Sock"

@MattKotsenas I wish I could figure out how to do that on windows 😅

@andrewlocknet There must be something in the water: matt.kotsenas.com/posts/aspire-i… You also might be able to mount your ssh-agent read-only to solve your signing issue

Blogged: Running AI agents safely in a microVM using docker sandbox andrewlock.net/running-ai-age… In this post I show how to run AI coding agents safely while still using YOLO/dangerous mode using docker sandboxes and the sbx tool #ai #docker #ClaudeCode

@KooKiz @wavetermdev What features were missing? Anything I care about? 😉

I tried @wavetermdev, unfortunately it's missing some critical features for me to adopt it, but I'm really jealous at their tab management. Just drag the tabs around to reorganize them, and it works with zero learning curve. Why aren't all terminals like this? I'm a Windows guy, I don't want to learn a bunch of keyboard shortcuts just to organize my tabs.

Blogged: Configuring contextual options with Microsoft.Extensions.Options.Contextual andrewlock.net/configuring-co… In this post I take a brief look at the Microsoft.Extensions.Options.Contextual package to understand what it's for, how to use it, and decide whether to use it #dotnet

Blogged: Splitting the NetEscapades.EnumGenerators packages: the road to a stable release andrewlock.net/splitting-the-… In this post I describe the recent architectural changes to the NetEscapades.EnumGenerators package, which is now a metapackage, to support more scenarios #dotnet

Creating Standard and "Observable" Instruments - andrewlock.net/creating-stand… @andrewlocknet

@jsneedles @marcgravell That's already available 😄

@marcgravell cc: @andrewlocknet Maybe some things to steal for EnumExtensions (still among my favorite libs) 🎉

The enquickening continues; have made case-sensitive and insensitive work in similar time now. But most importantly: parse from bytes rather than chars. Does it handle unicode? No. Does it handle flags? Also no. Does most protocol token parsing involve those things? Again, no!

Blogged: Recording metrics in-process using MeterListener andrewlock.net/recording-metr… In this post I show how you can use MeterListener to listen to Instrument measurements, how to trigger Observable measurements, and how to aggregate values #dotnet #observability

Sometimes the best takeaway from a source generator review is that the underlying API is already well designed. If the manual code is simple and performant, maybe a generator isn't needed. Good analysis from @andrewlocknet on #dotnet metrics andrewlock.net/creating-stron…

#dotnet has had built in metrics APIs since .NET 6, but many teams still aren't using them for custom application or business metrics. This post by @andrewlocknet covers what's available and how to get started with System.Diagnostics.Metrics andrewlock.net/creating-and-c…

Blogged: Creating standard and "observable" instruments andrewlock.net/creating-stand… In this post I discuss the various Instrument<T> types exposed by the System.Diagnostics.Metrics API and show examples from the .NET libraries and ASP .NET Core #dotnet #observability

New issue of .NET R&D Digest! Thx to @rfleury, @unmeshjoshi, @martinfowler, @simonw, @ricomariani, @andrewlocknet, @AntonMartyniuk, @stevejgordon, @KooKiz, @chnasarre, @meziantou, @markrichardssa, @STeplyakov and other g8 authors for g8 content! olegkarasik.wordpress.com/2026/02/02/net… #dotnet

Blogged: Exploring the (underwhelming) System.Diagnostics.Metrics source generators andrewlock.net/creating-stron… In this post I explore the source generators shipped in Microsoft.Extensions.Telemetry.Abstractions, explore the code, and discuss whether I would use them #dotnet

@sandertenbrinke Thanks, fixed!

@andrewlocknet There's an unfinished sentence in the "the word metric is often.." paragraph. :)

Blogged: Creating and consuming metrics with System.Diagnostics.Metrics APIs andrewlock.net/creating-and-c… In this post I provide an introduction to the System.Diagnostics.Metrics API, show how to create a custom metric, and show how to read it with dotnet-counters #dotnet

Blogged: Making foreach of an IEnumerable allocation-free, using reflection and dynamic methods andrewlock.net/making-foreach… In this post I describe why foreach sometimes allocates, and show how you can use DynamicMethod and Reflection.Emit to go allocation-free #dotnet #csharp

@KooKiz I've been using it for a couple of weeks and I've not seen a single crash, or even a bug. I've since spotted other missing features, like zip file handling etc, but the speed has still been worth it so far

@andrewlocknet I'm curious to see what your experience will be on the long run. I give Files and File Pilot a new chance every few months, and every time I revert after a few days. The last time it was because File Pilot crashed twice. x.com/KooKiz/status/…

Blogged: The Windows File Explorer replacement, File Pilot, is awesome andrewlock.net/windows-explor… In this post I describe my experience with the Windows File Explorer replacement, File Pilot. It's blazingly fast, feature rich, and has hotkeys everywhere

Blogged: Recent updates to NetEscapades.EnumGenerators: new APIs and System.Memory support andrewlock.net/updates-to-net… In this post I describe the recent changes to the NetEscapades.EnumGenerators source generator including support for the System.Memory package and new APIs #dotnet
