Blogged: Things That Caught My Attention Last Week - November 9 https://t.co/FaEg7uT9CG #dotnet

11:11 November 11. Remembering...

[Mitchel Sellers @mitchelsellers]

.NET 11 is here. Your production apps do not have to move today. They do need a plan that is not "we'll look later."

.NET 11 is a Standard Term Support release. .NET 10 is the LTS, supported until November 2028. Either can be the right choice, as long as you choose it on purpose.

The cheapest way I know to make that choice with evidence is a canary build: production stays on .NET 10, while a non-blocking CI job builds and tests the same code on .NET 11 every week as a reference/example/validation.

In the post:

• One MSBuild property that switches the target framework
• A GitHub Actions canary job that is allowed to fail
• How global.json and the canary interact
• A build-time warning for an end-of-life SDK
• The checks a green build will not tell you about

Anyone else periodically have issues with Nuget package proxies when many packages with interdependences are released? e.g. "error NU1103: Unable to find a stable package ..."? #Dotnet

[Peter Ritchie 💭 @peterritchie]

@GergelyOrosz Big design up front was tried for decades with poor results until agile came along. Not a panacea, but experienced software engineers recognize that software is ever evolving based on usage feedback, there is never a single description of what the software should do.

[Peter Ritchie 💭 @peterritchie]

@GergelyOrosz I've noticed this too. I think it stems from early "vibe coding" claims. People incorrectly believe they can have AI write an entire software system with one prompt.

This reminds me of I Am Legend

They should have heeded the warnings of General Protection Fault.

Probably the wrong person to put in charge of your military IT security

@bwhambi That looks like it was dug out of the New Mexico desert.

[Peter Ritchie 💭 @peterritchie]

@davidmohara I get some strange satisfaction with flushing the toilet when I encounter that.

[Peter Ritchie 💭 @peterritchie]

@ShawnWildermuth "Magician" or "genie" 😀

[Peter Ritchie 💭 @peterritchie]

@JoeMayo @HishmateX Yes, a "quote" in software doesn't benefit the author of the quote. AI has made people forget that it's near impossible to unambiguously define software scope before implementation, and when you do you all parties end up disappointed.

[Peter Ritchie 💭 @peterritchie]

@bwhambi Hold a couple glasses of water to give it purpose 😀

@debs_obrien If there's no benefit to you to share personal data, it's best to keep it private, IMHO.

[Peter Ritchie 💭 @peterritchie]

@draginol @TheRichWoods Think of all the water we don't use when showering...

[Jeff Fritz @csharpfritz]

The challenge I see with it is that Microsoft has had a very predictable schedule with layoffs since 2020.

The concern I'm hearing is: "If I don't take this one, what does the 'involuntary exit offer' look like?"

Some of the smartest and creative folks in software work at Microsoft and don't deserve to be threatened every 6 months with a layoff

In the year 2000, Joel Spolsky (founder of Stack Overflow) wrote a famous article titled “Things You Should Never Do, Part I.” In it, he talks about how rewriting your code from scratch is the single worst strategic mistake any software company can make. However, times have changed.

The cost of writing software is dropping exponentially and that has changed the math entirely on if it is worth rewriting your codebase. For instance, this year Anthropic’s Jarred Sumner ( @jarredsumner ) rewrote Bun in Rust in 11 days leading to many performance and correctness benefits.

Likewise, Stephen Toub (Distinguished Engineer at Microsoft, @stephentoub ) rewrote the GitHub Copilot runtime (400,000-line codebase) in Rust by himself. I thought it’d be interesting to lay out everything he learned in the process. So I interviewed him about how and why he did it.

In this episode:

• Why he choose Rust of all languages
• Rollout strategies (incremental vs all at once)
• How he prevented regressions
• Steering agents and which models he used
• Career lessons and engineering advice

In case you're wondering how old the C language is.

'One of the main causes of the fall of the Roman Empire was that-lacking zero-they had no way to indicate successful termination of their C programs.' — Robert Firth

#UnigetUI Because there are so many package managers that the package managers need a package manager manager. https://t.co/TVNk0gS8G6
