New year's getaway to Frankfurt.
Night photo is the opera house, we are going to see Tosca tonight.
Tried also some Sinn divers this morning in the old town boutique. Some are filled with oil and can go 5 km deep (not a typo!). But did not purchase any in the end.

That was an interesting read.
That is why I want to self-publish, I want full control of the content and how to present it, among other things. My book is going to be rigurous and comprehensive you-are-here-for-the-real-deal.

I canceled my book deal
I've always wanted to write a book, and I was close, but not this time.

Given a class object `klass`, it is not uncommon to see
klass.to_s
to get its name.
However, that is unnecessarily indirect. If you want the class name, just ask for it!
klass.name
That is more concise/intentional.

Will the future develop some sort of declarative language from which LLMs can produce implementations?

I have released Zeitwerk 2.7.4.
It improves the performance of some validation logic. This may be measurable in large apps with ignored directories and lots of autoload paths.
In Gusto's main application (+20 autoloaders, ~2000 autoload paths), the patch saves 800 ms of boot time.

Next week I’ll be at the last Railshöck of the year, in Zurich.
There will be talks by Alessandro Rodi, @marcoroth.dev, and yours truly. It's going to be a good one.
Being Switzerland, I am leaving my credit card at home 🤣.

We are going to see Tristan und Isolde in January, and are preparing for it these days.
Oh man, the music is always in flux, never resolves, four hours of tension without rest. When a resolution could land, you are taken elsewhere.
And the singers, so demanding, don't know how they can do it.

The next version of the Herb Language Server will ship with "unnecessary diagnostics" for all ERB control flow tags!
It dims any branches or expressions that are unnecessary, helping you quickly see which parts aren’t used or executed. 🌿

My birthday made me suspect the horoscope was a scam very early in my life.
I was born on the 20th of January. Being a small kid I noticed in some magazines I was Capricorn and in others Aquarius. So I had two different predictions! WTF!!!!
The system was obviously inconsistent. Done with it.

In Ruby, `::` is an _operator_ and it is _binary_.
So,
A::B::C::D
goes by pairs (like `+`) and performs intermediate lookups:
((A::B)::C)::D
You can actually write it like that.
More on that in my forthcoming book about constants in Ruby I am committed to finish within this century.

Letting Puma auto-set your worker count is the easiest way to go for 90% of usecases.
Currently, you can only do that with WEB_CONCURRENCY=auto, but we'll also make this possible in the next puma version by using `workers :auto` in your puma.rb.
