Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link in the table of content jumps at the copy of the answer on this page.
• The link on the answer itself points back at the original post.

Installing Debian 8.5 "jessie" on a Lenovo X1 Carbon 4th generation (20FB) - 2016

UPDATE 2018-02-24: I got a new Lenovo X1 Carbon 5th gen and tried to do the same setup with Debian 9.3.0. It was an utter failure because of some boot issues. I went with Xubuntu instead and everything works FLAWLESSLY. Xubuntu is beautiful.

I've had my mind on switching my development machine from a 13" MacBook Pro Retina to a Lenovo X1 Carbon running Linux for a while. The main reason is getting more familiar with Linux itself and also to have a more stable and minimal dev environment. So I finally got the machine and decided to install Debian 8.5 "jessie". Why Debian? Well, I tried installing Arch Linux once and couldn't get past getting wifi to work, and Ubuntu seemed like it added too much stuff. The choice was either Debian or Linux Mint. I went with Debian because it seems like it's the most stable.

I followed the instructions at https://www.debian.org/releases/jessie/amd64/ch04s

Quicklisp badge

Quickdocs.org now provides project badges for Quicklisp projects. It shows Quicklisp dist version when the project was updated last.

Once the project owner adds this badge to their README file, it will inform the project is ready for Quicklisp and its documentation is available on Quickdocs.org.

Stability

It's available, however it was just added in this morning at whim and it may still have issues. Please try it and tell @nitro_idiot if you encountered any issues.

; After working on a short example on TCP, I found the

Reader Macros in Common Lisp

This post also appears on lisper.in.

Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.

Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):

The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. ...read-macros... do their work at read-time.

Since this is on Hacker News and reddit...

• No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
• I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
• Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
• My use of type * name, however, is entirely intentional.
• If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le
