I said it at the time (and before!), but I truly believe that American voters electing Donald Trump for a second term in 2024 was the dumbest and most self-harming choice made by an electorate in the history of humanity

The Economist is treating Musk the same way centre right parties are treating the far right: way too nice. Minton Beddoes merely tickled him, yet he showed his resentful self. Why are there so few liberals who understand that you can’t accommodate the far right?

WTF this is costing me dollars now, unacceptable:

After 2 hours 😱:

AI subsidies were never going to last. Anthropic is committing $15B/year to SpaceX for data centers while Big Tech cuts jobs to fund AI infrastructure. Now GitHub and Anthropic are moving heavy consumer usage patterns from flat rate to metered plans. The free lunch is almost over.

A nice dashboard to keep track of all the PR's in the dotnet MAUI universe that are being done with AU agentic-engineers.net/dashboard/

2016 web developer worries: "man, divs really are hard to center!" 2026 web developer worries: "there are 639 compromised npm package versions in tonight’s Mini Shai-Hulud wave"

While burning tokens I keep thinking "and many Bothans have died for this"

@wildermuth.com I guess you are somewhere around here too

If only....

I will believe Microsoft has moved to a full agent based coding style with insane claimed productivity if they fix .NET Hot Reload and dotnet watch overnight.

They killed 180 children and their teachers in a double-tap strike on a school. The girls were 7 to 12 years old.

2026: party like its 1999 with Microsoft Access apps - read: vibe coded - apps by clever end users - all over the place entrenched in businesses? Catastrophe in the making or blessing?

High school students using AI to write college application essays that are then graded by AI from admissions departments is a great example of how AI usage devalues systems while people can accurately point to “productivity gains” from using AI.

There seems to be an ongoing supply chain attack or suspicious activity on NuGet .org, where a user called darklord is trying to gain legitimacy or something by sending thousands of become owner of their packages requests, don't accept, report to @nuget.org #dotnet #nuget
