Go Programming

11. Official Go font

+
+The Go programming language has an official font called "Go Font." It was created to complement the aesthetic of the Go language, ensuring clear and legible rendering of code. The font includes a monospace version for code and a proportional version for general text, supporting consistent look and readability in Go-related materials and development environments.
+
+Check out some Go code displayed using the Go font:
+
+
+
+https://go.dev/blog/go-fonts
+
+The design emphasizes simplicity and readability, reflecting Go's philosophy of clarity and efficiency.
+
+I found it interesting and/or weird, as Go is a programming language. Why should it bother having its own font? I have never seen another open-source project like Go do this. But I also like it. Maybe I will use it in the future for this blog :-)
+
+

12. Go functions can have methods

+
+Functions on struct types? Well, know. Functions on types like int and string? It's also known of, but a bit lesser. Functions on function types? That sounds a bit funky, but it's possible, too! For demonstration, have a look at this snippet:
+
+ +

package main
+
+import "log"
+
+type fun func() string
+
+func (f fun) Bar() string {
+        return "Bar"
+}
+
+func main() {
+        var f fun = func() string {
+                return "Foo"
+        }
+        log.Println("Example 1: ", f())
+        log.Println("Example 2: ", f.Bar())
+        log.Println("Example 3: ", fun(f.Bar).Bar())
+        log.Println("Example 4: ", fun(fun(f.Bar).Bar).Bar())
+}
+

+
+It runs just fine:
+
+ +

❯ go run main.go
+2025/02/07 22:56:14 Example 1:  Foo
+2025/02/07 22:56:14 Example 2:  Bar
+2025/02/07 22:56:14 Example 3:  Bar
+2025/02/07 22:56:14 Example 4:  Bar
+

+
+

macOS

+
+For personal computing, I don't use Apple, but I have to use it for work.
+
+

13. ß and ss are treated the same

+
+Know German? In German, the letter "sarp s" is written as ß. ß is treated the same as ss on macOS.
+
+On a case-insensitive file system like macOS, not only are uppercase and lowercase letters treated the same, but non-Latin characters like the German "ß" are also considered equivalent to their Latin counterparts (in this case, "ss").
+
+So, even though "Maß" and "Mass" are not strictly equivalent, the macOS file system still treats them as the same filename due to its handling of Unicode characters. This can sometimes lead to unexpected behaviour. Check this out:
+
+ +

❯ touch Maß
+❯ ls -l
+-rw-r--r--@ 1 paul  wheel  0 Feb  7 23:02 Maß
+❯ touch Mass
+❯ ls -l
+-rw-r--r--@ 1 paul  wheel  0 Feb  7 23:02 Maß
+❯ rm Mass
+❯ ls -l
+
+❯ touch Mass
+❯ ls -ltr
+-rw-r--r--@ 1 paul  wheel  0 Feb  7 23:02 Mass
+❯ rm Maß
+❯ ls -l
+
+

+
+

14. Colon as file path separator

+
+MacOS can use the colon as a file path separator on its ADFS (file system). A typical ADFS file pathname on a hard disc might be:
+
+

+ADFS::4.$.Documents.Techwriter.Myfile
+

+
+I can't reproduce this on my (work) Mac, though, as it now uses the APFS file system. In essence, ADFS is an older file system, while APFS is a contemporary file system optimized for Apple's modern devices.

+
+

15. Polyglots - programs written in multiple languages

+
+A coding polyglot is a program or script written so that it can be executed in multiple programming languages without modification. This is typically achieved by leveraging syntax overlaps or crafting valid and meaningful code in each targeted language. Polyglot programs are often created as a challenge or for demonstration purposes to showcase language similarities or clever coding techniques.
+
+Check out my very own polyglot:
+
+The fibonatti.pl.c Polyglot
+
+

16. Languages, where indices start at 1

+
+Array indices start at 1 instead of 0 in some programming languages, known as one-based indexing. This can be controversial because zero-based indexing is more common in popular languages like C, C++, Java, and Python. One-based indexing can lead to off-by-one errors when developers switch between languages with different indexing schemes.
+
+Languages with One-Based Indexing:
+
+

Fortran
MATLAB
Lua
R (for vectors and lists)
Smalltalk
Julia (by default, although zero-based indexing is also possible)

+foo.lua example:
+
+ +

arr = {10, 20, 30, 40, 50}
+print(arr[1]) -- Accessing the first element
+

+
+ +

❯ lua foo.lua
+10
+

+
+One-based indexing is more natural for human-readable, mathematical, and theoretical contexts, where counting traditionally starts from one.
+
+

17. Perl Poetry

+
+Perl Poetry is a playful and creative practice within the programming community where Perl code is written as a poem. These poems are crafted to be syntactically valid Perl code and make sense as poetic text, often with whimsical or humorous intent. This showcases Perl's flexibility and expressiveness, as well as the creativity of its programmers.
+
+See this Poetry of my own; the Perl interpreter does not yield any syntax error parsing that. But also, the Peom doesn't do anything useful then executed:
+
+ +

# (C) 2006 by Paul C. Buetow
+
+Christmas:{time;#!!!
+
+Children: do tell $wishes;
+
+Santa: for $each (@children) { 
+BEGIN { read $each, $their, wishes and study them; use Memoize#ing
+
+} use constant gift, 'wrapping'; 
+package Gifts; pack $each, gift and bless $each and goto deliver
+or do import if not local $available,!!! HO, HO, HO;
+
+redo Santa, pipe $gifts, to_childs;
+redo Santa and do return if last one, is, delivered; 
+
+deliver: gift and require diagnostics if our $gifts ,not break;
+do{ use NEXT; time; tied $gifts} if broken and dump the, broken, ones;
+The_children: sleep and wait for (each %gift) and try { to => untie $gifts };
+
+redo Santa, pipe $gifts, to_childs;
+redo Santa and do return if last one, is, delivered; 
+
+The_christmas_tree: formline s/ /childrens/, $gifts;
+alarm and warn if not exists $Christmas{ tree}, @t, $ENV{HOME};  
+write <111
+ and send the
+EMail
+;wait and redo deliver until defined local $tree;
+
+redo Santa, pipe $gifts, to_childs;
+redo Santa and do return if last one, is, delivered ;}
+
+END {} our $mission and do sleep until next Christmas ;}
+
+__END__
+
+This is perl, v5.8.8 built for i386-freebsd-64int
+

18. CSS3 is turing complete

+
+CSS3 is Turing complete because it can simulate a Turing machine using only CSS animations and styles without any JavaScript or external logic. This is achieved by using keyframe animations to change the styles of HTML elements in a way that encodes computation, performing calculations and state transitions.
+
+Is CSS turing complete?
+
+It is surprising because CSS is primarily a styling language intended for the presentation layer of web pages, not for computation or logic. Its capability to perform complex computations defies its typical use case and showcases the unintended computational power that can emerge from the creative use of seemingly straightforward technologies.
+
+Check out this 100% CSS implementation of the Conways Game of Life:
+
+
+
+CSS Conways Game of Life
+
+Conway's Game of Life is Turing complete because it can simulate a universal Turing machine, meaning it can perform any computation that a computer can, given the right initial conditions and sufficient time and space. Suppose a language can implement Conway's Game of Life. In that case, it demonstrates the language's ability to handle complex state transitions and computations. It has the necessary constructs (like iteration, conditionals, and data manipulation) to simulate any algorithm, thus confirming its Turing completeness.

20. The biggest shell programs

+
+One would think that shell scripts are only suitable for small tasks. Well, I must be wrong, as there are huge shell programs out there (up to 87k LOC) which aren't auto-generated but hand-written!
+
+The Biggest Sell Programs in the World
+
+My Gemtexter (bash) is only 1329 LOC as of now. So it's tiny.
