Creating binaries

You can create portable binaries with Racket's raco command! Use raco exe and raco distribute.

Sample games

Racket provides a executable plt-games, when ran (from console) it opens a menu of miscellaneous games, among them: jewel, minesweeper, aces, spider, checkers. & more (20 games total).

Plots

You can plot data in 2d & 3d forms.

2D

Sample code:

1
2
3
4
5
6

#lang racket/base
(require racket/gui/base racket/math plot)

(plot-new-window? #true)

(plot (function sin (- pi) pi #:label "y = sin(x)"))

3D

Sample code:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

#lang racket/base
(require racket/gui/base racket/math plot)

(plot-new-window? #true)

(plot3d
 (surface3d (lambda (x y) (* (cos x) (sin y)))
            (- pi) pi (- pi) pi)
 #:title "An R × R → R function"
 #:x-label "x" #:y-label "y" #:z-label "cos(x) sin(y)")

Browser

There's a included library to render web pages, just "(require browser)".

Sample code:

1
2
3
4

#lang racket
(require browser)

(open-url "https://xgqt.gitlab.io/")

FFI

You can use Racket's Foreign Function Interface to interact with non-Racket libraries to make use of very fast libraries written in (mainly) FORTRAN & C.

For example sci uses FFI for CBLAS & LAPACK.

Parallelism

For greater speed up with parallel execution there are futures, places and distributed places (for distributed programming).

Git

Because contents of this blog are stored in a git repository you can just

1

git clone --verbose --recursive https://gitlab.com/xgqt/blog

then, read the "raw" ORG files in 'posts' directory or make the HTML version executing the 'dev.sh' script (remember that you will need GNU Emacs to render the posts into HTML files).

Then, you can just git pull to read the news whenever you wish, maybe do it with cron or a script that will pull many repos at once, for example with this script.

RSS

Org-Static-Blog creates a RSS Feed file rss.xml, so to subscribe add the link https://xgqt.gitlab.io/blog/rss.xml to your favorite RSS reader.

You can also subscribe to the GitLab repository Atom feed.
