Seems like this is going to be the year of AI slop being released everywhere by Microsoft. Just wish they'd put as much effort into a post morten for this one as they're doing for a diagram on a blog post https://github.com/microsoft/onnxruntime/issues/27263#issuec...

Maybe I'm not seeing it but wouldn't it be just easier to pump the river water back up instead of letting it flow on the sea?

Show HN: Library to help find memory leaks for C#

theolivenbaum — Tue, 09 Dec 2025 21:20:31 +0000

I got tired of shelling out to dotnet-gcdump to investigate memory leaks, so I made a tiny C# library that lets you trigger .gcdump captures programmatically. Useful for debugging memory leaks, taking snapshots before/after operations, or grabbing dumps automatically in CI.

There are some minor breaking changes like the order of iteration is not always the same as the official Linq implementation, or Sum might give different values due to checked vs unchecked summing. Probably not an issue for most people, but a subtle breaking change nevertheless.

To add on that, you can define your lambdas as static to make sure you're not capturing anything by mistake.

Something like dates.Where(static x => x.Date > DateTime.Now)

Netflix did that many years ago, interesting idea even if a bit disruptive in the beginning https://netflix.github.io/chaosmonkey/

New comment by theolivenbaum in "Defending Open Source: Protecting the Future of WordPress"

theolivenbaum — Mon, 18 Nov 2024 08:47:55 +0000

What a bunch of corporate newspeak. Their demand of 8% of gross revenue in annual license fees, or >$30M for 2024, shows how much this was only about profits and not about contributing to the WP community:

"It’s important to note that a significant part of Automattic’s revenue, including any licensing revenue, is channeled back into supporting the WordPress community, as Automattic is currently contributing 3,552 hours per week to the WordPress project. This comes out to something in the order of $20M annually in salaries."

And the post then goes from defending open source to how their actions made everyone's websites safer (which, they didn't) and how you should migrate your website to their hosting solution. Despicable.

Isn't that precisely what they were doing? Forcing landlords to follow the recommended prices?

They turned into an online version of the mob. Pay them and they'll take care that your bad reviews are gone. Don't pay and risk getting a few extra bad reviews
