“Using the REPL” actually means typing your code in your favorite editor. However, one sends the code to evaluate in a REPL, which may not even be visible at all. Once the code is evaluated, the results immediately show up in the editor, so you get the feedback right away. Obviously, this requires some upfront setup, but a proper Clojure REPL setup exists in all major editors. Just google it.
Note that one normally sends the code to evaluate with a single key stroke. Note also, a very important point that people often miss, is that this “sending code to evaluate” is uniquely convenient in Lisp because of the parentheses.
There’s a notion of “form” in Lisp, that is the code enclosed between a pair of parentheses, which can be independently evaluated. So, when next time someone insists that their favorite non-Lisp language also has a REPL, ask them, does it have a notion of “form”?
The benefit of a form, is that one no longer needs to use a mouse or some awkward key combinations to painstakingly select a region of code first, before sending it out for evaluation. Instead, one can use a single key stroke that means “evaluate the form under the cursor”, or “evaluate the form before the cursor”, etc, to precisely define the scope and send the code at the same time. — How much can a Clojure developer do alone?

On IRC, features like embedded images, a nice UX for messages longer than a few lines (e.g. pasted code), threaded messages, etc; are absent. Some sort of “graceful degradation” to support mixed channels with clients which support these features and clients which don’t may be possible, but it still degrades the experience for many people. By instead making everyone work within the limitations of IRC, we establish a shared baseline, and expressing yourself within these limitations is not only possible but makes a better experience for everyone. — Absence of certain features in IRC considered a feature

I could say that Twitter, Facebook, Youtube, and Google helped ruin the internet, but really it was that everyone started using it. The internet used to be a haven for nerds, geeks, artists, and bohemian misfits until the cool kids crashed it. Now the internet is dull and stale and overly commercialized. — I miss the old internet

The problem with most of these comments is that they convey very little information. Often it is just a repetition of the method name and parameter names in a few more words. These comments may be useful for API:s exposed externally, but in an application where you have access to all the source code, they are mostly useless. If you wonder what the method does, or what the valid input range for a parameter is, you are better off just reading the code to see what it does. These types of comment take up a lot of space without providing much value. — On Comments in Code

2021-06-17: > Not only in a professional context, but also for private purposes it does make sense to actively read your books/articles. Try to apply some analytical reading, a concept I’ve read about for the first time in How to read a book (book). The idea is to interact with the content you’re reading about: Ask questions, try to link ideas in your mind, make notes, lookup complex definitions. The worst thing you can do is to just passively read something, finish it and then you move on to your next reading. — Note taking in 2021

When you are a kind of old school, modern times means a bit of pain in some way. Your soul is mostly seeking inner peace but on the other hand, as someone that works with technology, you wouldn’t stay freeze.
And sometimes the thing is the other way around, it feels that the old-school-world you’re living with is good but not as great as it should and you need to move a bit forward yourself to - wrongly - have a feeling of progress. — Mattermost and Matterbridge

Bunch of years ago, when social networks did not exist (wow) the web prettended to be pretty simple. As simple that some content management systems were designed to do a kind of hard work: build a static site from the dynamic one. Easier to be served, maintained and much much faster… win-win!. — Stay static

Two things Perl 5 got right was its lexical scoping rules and support for anonymous functions (“lambdas”). Combine those features and you can make closures. And just what are closures good for? Well it turns out they’re pretty damn powerful; powerful enough, in fact to make a better object system than Perl’s built-in offering. — Perl Closures As Objects

For simple expressions, parentheses are a form of static typechecking. If you model a Lisp as a stack language that evaluates from right to left, each parenthesized block must push exactly one value onto the stack, and must not consume any values. — Parentheses are Just Typechecking
