Updating to .NET 8, updating to IHostBuilder, and running Playwright Tests within NUnit headless or headed on any OS

I've been doing not just Unit Testing for my sites but full on Integration Testing and Browser Automation Testing as early as 2007 with Selenium. Lately, however, I've been using the faster and generally more compatible Playwright . It has one API and can test on Windows, Linux, Mac, locally, in a container (headless), in my CI/CD pipeline, on Azure DevOps, or in GitHub Actions. For me, it's that last moment of truth to make sure that the site runs completely from end to end. I can write those Playwright tests in something like TypeScript, and I could launch them with node, but I like running

Open Sourcing DOS 4

See the canonical version of this blog post at the Microsoft Open Source Blog ! Ten years ago, Microsoft released the source for MS-DOS 1.25 and 2.0 to the Computer History Museum, and then later republished them for reference purposes. This code holds an important place in history and is a fascinating read of an operating system that was written entirely in 8086 assembly code nearly 45 years ago. Today, in partnership with IBM and in the spirit of open innovation, we're releasing the source code to MS-DOS 4.00 under the MIT license. There's a somewhat complex and fascinating history behind th

Webcam randomly pausing in OBS, Discord, and websites - LSVCam and TikTok Studio

I use my webcam constantly for streaming and I'm pretty familiar with all the internals and how the camera model on Windows works. I also use OBS extensively, so I regularly use the OBS virtual camera and flow everything through Open Broadcasting Studio. For my podcast, I use Zencastr which is a web-based app that talks to the webcam via the browser APIs. For YouTubes, I'll use Riverside or StreamYard, also webapps. I've done this reliably for the last several years without any trouble. Yesterday, I started seeing the most weird thing and it was absolutely perplexing and almost destroyed the d

Automatically Signing a Windows EXE with Azure Trusted Signing, dotnet sign, and GitHub Actions

Mac Tahoe (in Beta as of the time of this writing) has this new feature called Edge Light that basically puts a bright picture of an Edge Light around your screen and basically uses the power of OLED to give you a virtual ring light. So I was like, why can't we also have nice things? I wrote ( vibed, with GitHub Copilot and Claude Sonnet 4.5 ) a Windows Edge Light App (source code at https://github.com/shanselman/WindowsEdgeLight and you can get the latest release here https://github.com/shanselman/WindowsEdgeLight/releases or the app will check for new releases and autoupdate with Updatum).

The danger of glamourizing one shots

People should not be judging AI-augmented coding by “1 shots.” If someone told you that their model did a “one shot of Minecraft” and they’re impressed by that, you need to consider how much semantic heavy lifting the word “Minecraft” is doing in that prompt. Ask them to one shot Minecraft without using the word Minecraft. It’s not trivial to one shot something unique, because programming is the art of making the ambiguous incredibly specific through sculpting. AI sculpting is less about vibes and more about finding the specificity you want and keeping the system stable through changes. Good S

Is the craft dead?

The Japanese are really good at woodworking. And I love watching the Yankee workshop, my dad makes Native American bows and arrows completely from scratch in his workshop with trees that he finds. This is all different from the stuff you get at IKEA, but I’ve been coding now for money for 35 years and systems are still complicated, computers still do dumb stuff, humans still do dumb stuff, this is just like the move from assembler to C, like the introduction of syntax highlighting, the introduction of intellisense, and the copy paste directly into production shift when stack overflow happened.

Migrating a Synology NAS to a UniFi UNAS Pro 8 with Robocopy, SMB Multichannel, and Surprising Performance Traps

I’ve had a Synology NAS for a very long time , and recently I started moving its contents to a new Ubiquiti UniFi UNAS Pro 8 . This seemed like it ought to be a fairly boring operation. Both devices speak SMB, I have a fast network (recently upgraded to 10 gigabit internally), and Windows has had tools for copying files reliably between machines for decades. Naturally, it turned into a whole evening of learning things I thought I already knew, which is why I started a blog lol. There was a nice bit of history here for me because back in 2007 (good lord!) I wrote a post called “ XCo

Debugging my new network, when 10 Gigabit Ethernet Runs at 300 Megabits

I've been moving my home storage over to a UniFi UNAS Pro 8 as part of a larger homelab moderization . My main IRONHEART (the ultimate PC from a few years back) desktop now has an Intel E610-XT2 10GbE card, the NAS is on 10GbE, and there's a Minisforum MS-01 miniPC on the same network with a 10GbE SFP+ connection running Immich and Portainer and a few other things. Everything says 10 gigabit. Windows says 10 gigabit. UniFi says 10 gigabit. SMB copies are using the correct NIC but my file copies are running at around 100 to 200 megabits per second which is sad making. Naturally, I blamed the NA

Article: Systemic Approach to Memory, Knowledge, and Context in Agentic AI Architectures

The article argues that reliable agentic AI architecture depends on a context engine that selects, injects, compresses, and expires information before it reaches the model. It separates context, memory, and knowledge, and recommends tiered memory, curated knowledge, and token budgeting. It also covers common anti-patterns, such as context stuffing and stale data loops, with mitigations. By Adi Polak

Meta Sued Over Using People’s Photos for AI and Facial Recognition

There's a new proposed class action lawsuit against Meta that alleges they harvested Facebook and Instagram photographs for biometric information that was used to train image generation models and develop an, as yet, unreleased facial recognition feature called Nametag for smart glasses. Meta says that the lawsuit has misrepresented the situation and notes that Nametag […] The post Meta Sued Over Using People’s Photos for AI and Facial Recognition appeared first on Light Stalking .

Turning Woe Back To Wow in Photography

I have often said that there are six stages to a photographer’s life. The very first is wow, that moment when you realise that photography is for you, something that is going to consume you for many years to come. The second stage is woe. That’s the defining moment when you realise that there is […] The post Turning Woe Back To Wow in Photography appeared first on Light Stalking .

Dynamics of Colour Photo Contest Winners

One of the interesting things about the entries in this month's colour theme of “the dynamics of colour” is that so many of the strongest entries chose to use a single colour to draw the reader's interest and I think that says something quite powerful about the use of colour in photography.

Drone Photography Tips: Better Composition, Lighting and Angles

There's a common myth in drone photography where users will assume that getting the drone higher automatically produces better photos.

Improving performance by prefetching product pages from Etsy Search

Rarely are there opportunities for big, bold, game-changing improvements in web performance. The Speculation Rules API (SRA) is a recent browser development that offers just such an opportunity.

Reducing experiment duration with predicted control variates

This is a follow-up on how CUPED has evolved at Etsy since then. Spoiler – It’s changed a lot, decreasing our average experiment duration by 3 days! Etsy’s mission is to Keep Commerce Human. To achieve this, we need to understand the impact each change to our platform has on our buyers' and sellers' experience. Whether that involves changing the color of the “Buy Now” button on the Et
