Photoshop was ported to IRIX using Latitude, Quorum Software's implementation of Mac OS System 7. Apple later acquired the Quorum's code and it became part of Carbon.

Folks on the #clschool, #commonlisp, and #sbcl IRC channels can answer your questions.

One big problem is that Python's semantics make it difficult to implement the language efficiently. When I translate the sieve code into safe Common Lisp, I get a speedup of 15. Af…

There's a big difference between the complexity of setting up Bazel and the experience of using Bazel at a company where Bazel has been set up for you. As a user I love Bazel. When…

Fortunately, you can continue to use proto2, if you decide it's superior, or use a more recent version of proto3 that supports field presence.

A good book about this general topic is: https://books.google.com/books/about/Human_Factors_and_Typog...

The best way to acquire a quality sofa is to purchase a used one made by a furniture maker known to create high quality pieces. It requires a bit of research. You need to figure ou…

SBCL has been ported to RISC-V, so it has an assembler for that architecture.

When I was about ten, Chi Corp., which was associated with Case Western, had an open house. I keypunched my name on a card and fed it to a Univac 1108, which output a large image o…

Having broken a couple of kingpins at high speed on roller skates, it's definitely no fun. Unfortunately, the kingpins are under a lot of stress and they're threaded. Invariably, t…

A couple more details ... Good quality roller skate truck pivot pins end in a spherical ball and the pivot pin cup on the truck is also spherically machined. There's no bushing in …

One more thing ... Good quality skates have pivot pins whose length is adjustable. I don't know if skateboard trucks generally have this feature. You tighten and loosen the pressur…

Roller skating plate trucks are similar to skateboard trucks. Kingpin angle affects cornering ability. Kingpins at higher angle from vertical corner more sharply, so skaters doing …

I code my personal projects in Common Lisp because I like the language and because the code I write today will likely execute without modification 20 years from now.

The end of this post explains why Common Lisp can run much faster than Python. https://markmail.org/message/dp56i26zhpf4fehb#query:+page:1+...

Yes. At the end of the following Usenet post, the developer of a Python implementation compares the language features of Common Lisp to those of Python in order to explain why Lisp…

Neither.

Keyword highlighting is explicitly called out as an antipattern in the book Human Factors and Typography for More Readable Programs, which I highly recommend.

Anyone interested in syntax highlighting should read the book Human Factors and Typography for More Readable Programs. The majority of the book is devoted to non-color techniques, …

Common Lisp handles negative zero quite well.

I saw the film with two women who had essentially the same reaction, hating both Craig and the film. What exactly was he suffering from? Perhaps we're supposed to have unbounded sy…
