A handful of companies are going to infinity while all the rest go to zero. So just buy at least one share of one of those companies and you’ll have the same infinity dollars as everyone else.

There should be a rule that “nit: …” PR comments are only permitted when you review promptly.

Have people started saying “ralphable” yet? “Yeah that sounds hard, but it’s ralphable”

Lines of code produced was always a bad metric but it is now officially and forever removed of any and all meaning. Good riddance.

One of the critical things that distinguishes a senior developer from a junior developer is an understanding, deep in their bones, that the cost of DOING a thing is cheap compared to the cost of truly FINISHING a thing and utterly trivial compared to the cost of MAINTAINING a thing. Like 1:10:10000.

I find it funny that when you're done with a rental from a `MemoryPool`, you dispose the owner.

Copilot: "Let me read lines 1-50... Ok, let's read some more lines..." Read the whole file, bro, you're a computer!

I think somebody vibe coded floating point where it has no business being used at fidelity.com. I have 0.0003 shares of MSFT now. I had to subtract $0.01 from amount shown “available to withdraw” for it to stop saying “you don’t have enough cash”. 🙃

My favorite video game is typing things into this box and then erasing it because I realize nobody will care.

Foo(Bar()); Code review: LGTM — var x = Bar(); Foo(x); Code review: The type of ‘x’ is not apparent, don’t use var here. — Please explain to me how these are different. I legitimately don’t get it.

The people who think they are good at everything because they are good at coding are also bad at coding.

Does M365 Copilot re-pin itself to taskbar every time you reboot? I hope this is just a bug and not by design. I have sent feedback.

We’d have AGI already if we never invented uppercase letters, backwards slashes, and redundant ways to indicate the end of a line.

There are dumb people saying dumb things on the old site. I’m well aware and I don’t want a play-by-play.

I very much like Linux, but without fail anytime I see someone trying to "switch to Linux" I see a post in a few days saying "I updated my jinglehopper and now my beebeehams stopped working, any ideas?"

What’s the most abused feature in C# and why is it extension methods?

Thanks for the kind words, Kirill! You're a huge inspiration to me. I will echo the sentiment of many others here and say that if it weren't for msbuildlog.com, I never would have been able to have the impact that I've had.

Is there a way to configure format-on-save for a repo in Visual Studio like you can in Visual Studio code? I only want this on in repos that enforce formatting, not for any file I open.

Working on something.

Did someone already build an analyzer that lets you annotate the internals you actually want to share with friend assemblies, and then fire on any use of other internals? I searched but didn't find one.

I'm still upset that the root of my user profile and my Documents folder became free-for-all places for apps to store random things, but that ship has sailed. ☹️

I logged into X briefly to make my departure more permanent and this is how it felt

Always be skeptical of code comments that say, "we have to do this because ..." Very often, the reasoning is badly outdated.

Importing tweets is cool, but @bsky.app, please mark skeets with client-chosen timestamp distinctly somehow. In the meantime, be skeptical when you see “check the date on this skeet!”

I have gained more followers in one week on Bluesky than in two years on Mastodon.

“Domain names as handles! Genius! What an elegant solution to verification!” A few moments later: “Look famousperson dot bsky dot social is here!!!”

20 years later and this still haunts me everywhere I go. Stop it. try { … } catch (Bug bug) { DiscardStackAndBlameUser(bug); }

Which of these things will happen first? A. I stop hearing “this has to run on .NET Framework” daily? B. .NET 4.5 becomes old enough to vote?

Is there no polling feature on here?

We can debate the “fast and break things” part, but we must move.

Wow, you can simply delete the “for you”-equivalent feed? Glorious.

Hello friends! My Twitter account is now protected and abandoned and I'm shopping for a new car.
