Another example a web link that points to a page that no lnger exists.

It's a null pointer exception.

How does flint compare to to NuShell?

My current favorie pipe shell.

PS: your current readme reads like AI generated.

Which subconciusly makes me wonder:

If the author couldn't botter to write it, why should I botter to read it?

Thank you I was also expecting Literate Programming.

One of the clearest thinkers I had the privilege of knowing was Dr. Eli Goldratt author of Theory of Constraints.

Fortunately for us he defined as his life's mission to teach the world to think clearly.

So I suggest you start with three of his books: The Goal, Is not luck and The Choice. After trat read "The thinking Processes".

Apart from the theory of Constraints literature you can study system dynamics. And if you like programming then "Introduction to NetLogo" is great at both.

If you don't like programming then Zenge's the "Fifth Discipline" is a great intro to system dynamics.

Steve jobs killed it when said it would work on the iPhone because if the "huge" memory and battery resources. He said Javascript and HTML was everything you needed.

There is also verso / recto that uses the same technique.

I actually wish for a tool that would use two things: 1) navigate code like a file system: Class/function/lines [3..5]

2)allow us to use git commit revisions so that we could comment on the evolution of the code

So far the only thing capable has been leoEditor + org-babel

Eiffel is the language you are looking for. It's pre-conditions and post-conditions prove the properties of the code that you actually are executing.

The book that does the equivalent but with the properties checked at runtime is: Object Structures (like data structures but with objects).

New comment by elviejo in "When did people favor composition over inheritance?"

elviejo — Sun, 16 Nov 2025 15:03:54 +0000

In Eiffel we have multiple inheritance. It's such a powerful tool. And a natural way to model the world. For example if you think of your typical OOP book You have Vehicles with engines * cars that move on roads * planes that move on air * and boats that move on water.

But then comes an aqua-plane and it breaks your inheritance tree!

But with multiple inheritance is the most natural thing to have a plane that is also a boat and a car.

In Eiffel we favor the appropriate tool that better represents the world.

I agree with disabling history in youtube.com...

Now I only watch videos from my subscriptions as opposed to whatever the algorithm feed me.

elviejo — Wed, 17 Sep 2025 18:13:34 +0000

Code is not only code.

It's like saying physics it's just math. If we read:

F = m*a

There is ton of knowledge encoded in that formula.

We cannot evaluate the formula alone. We need the knowledge behind it to see if it matches reality.

With llms we know for a fact that if the code matches reality, or expectations, it's a happy accident.

Mmhhh how about a youtube version that looks like a usenet forum of my channel subscriptions. Where each video is a topic. The summary is part of the topics. Ideally the same software I use to read news groups should work for youtube.

The Goal and It's not luck by Goldratt.

Showed a better way to manage anything in particular ourselves.

Man's Search For Meaning by Viktor Frankl even in the darkest of times we kind find Meaning.

A Guide to the good life. The stoics found a way to handle our human experience 2500 years ago.

The mythical man month by Brooks. Everything we struggle with in software development we have been fighting since the 70s.

New comment by elviejo in "XMLUI"

elviejo — Sun, 20 Jul 2025 15:20:27 +0000

I applaud the idea of bringing back the Visual Basic model to the web. Again I don't expect people under 45 to remember how easy it was to develop a user interface that reacted to user actions.

I just don't see the need to create a new language to do it.

Firefox had XUL. And macromedia had Flex.

Flex was amazing it had an XML version and an OOP one.. that where two views of exactly the same language.

The Elon fan boys, are always under that impression. Plus the PR machine is always trying to create that impression. Take a look at the wikipedia page for Tesla, there has been an edit war for several years trying to create the impression that Elon created Tesla Motors.

I've been working on implementing @mpweiher "Storage Combinators" [0] and "polymorphic Identifiers" [1] in Eiffel [3].

Currently I'm stuck implementing a storage combinator with EiffelWebFramework[4]

Programming languages are extremely important yet we don't pay for them and their people that develop them.
