GitHub and Codeberg links on the site don't open for me. ("To protect your security, codeberg.org will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.") This is because of the use of frames:

  <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
      <html>
          <head>
              <title>Common Lisp Screenshots</title>

You can fix this by replacing the OVH feature with a regular redirect, like an `index.html` with a `<meta>` tag:

  <meta http-equiv="refresh" content="0; url=https://simple.photo/vindarel/c352e2c0177b24786fb40041657485dd/common-lisp-screenshots/">
If possible, you can also fix it by making your links on the https://simple.photo/ page open in a new window.

I like how the disclaimer went humble bragging about the range of usage.

>"Please don't assume Lisp is only useful for Animation and Graphics, AI, Bioinformatics, B2B and Ecommerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list."

>Kent Pitman

He left out Guessing Animals!

https://en.wikipedia.org/wiki/Kent_Pitman

>While in high school, he saw output from one of the guess the animal pseudo-artificial intelligence (AI) games then popular. He considered implementing a version of the program in BASIC, but once at the Massachusetts Institute of Technology (MIT), instead he implemented it in several dialects of Lisp, including Maclisp.

Until Vindarel gets the TLS working there's also a direct URL: (<https://simple.photo/vindarel/c352e2c0177b24786fb40041657485...>). It's a bit of a shame that there's no indication to what application each screenshot is from.

vindarel|15 days ago

Thank you, TLS should be fine now. (fixed ±12 hours ago)

Many of them do say which program they are from; at least the first of multiple are from the same program.

While not Common Lisp I've always found it pretty cool that AutoCAD shipped with a Lisp, making the language technically a hugely deployed commercial success.

Were it not for early exposure to Autolisp I would not have appreciated Lisp or Lisp-based systems, like Emacs, the way that I did. I might've ended up whinging that they didn't use a mOdErN language like JavaScript.

Autolisp definitely sent me down the left-paren path.

Nowadays it also supports .NET, COM and ObjectARX.

Just like Gimp eventually added support to Python alongside Script-Fu.

Which end up reducing the interest to reach out to Lisp languages.

The core route optimization algorithm of Routific is also written in Common Lisp :)

vindarel|15 days ago

That's awesome, thank you. How do you know it, is there a reference on the net somewhere?

The unfettered instrumental rationality of the techno-slob on full display. Bonus depravity-points if the multi-paragraph HN comments are also being outsourced to the Machine.

ChanderG|16 days ago

Depending on a corporation to do your programming (and burning half the planet in the process, pardon the hyperbole) is the very opposite end of the "hacker" ethos where Lisp stands. Very surprising to see this sort of comment on HN, of all places.

silcoon|16 days ago

Kind of yes and kind of no. Not many reasons to use Common Lisp I agree, but the Lisp idea itself has still something to offer that couldn’t be found in other systems.

I’m comfortable to declare that are not macros the most powerful thing of Lisp, but the concept of an environment. Still in 2026 many languages now implement the concept of evaluating the code and make it immediately available but nothing is like Lisp.

Lower level programming languages today they all still requires compilation. Lisp is one of the few that I found having the possibility to eval code and its immediately usable and probably the only that really relies heavily on REPL driven development.

Env+REPL imo is the true power still far ahead of other languages. I can explore the memory of my program while my program is running, change the code and see the changes in real time.

The issue is that CL is old, and Clojure is so close to be perfect if it wasn’t for Java. Clojure replaces Java, not CL and this is its strength but also its weakness.

rootnod3|16 days ago

Can your LLM do that to a running system? Or will it have to restart the whole program to run the next iteration? Imagine you build something with long load-times.

Also, your Lisp will always behave exactly as you intended and hallucinate its way to weird destinations.

blue1|16 days ago

High level programming languages were conceived by humans and for humans. Will AIs in future better use their own languages, or maybe even output machine language directly?

WolfeReader|16 days ago

We have enough headlines about LLMs already. Let's just enjoy a cool Lisp site without some AI advocate telling us that non-AI things are irrelevant.

lgrapenthin|16 days ago

You are comparing a PL to a text generator. What are you on?
