** Miscellaneous this and that **
Since my brain injury (which I’ve since learned can be called an“ABI” or“acquired brain injury”) I’ve noticed that I have trouble focusing on programming tasks; I’m able to do what I need to do for work and family but, when it comes time for hobby projects I’m just gloop. Totally oozy.
Because of that I’ve been drawn to do more reading and game playing, but also still wanna code…I’ve found that it is easier to use more“batteries included” kinda languages, namely scheme, over what I’d … ⌘ Read more

** My programming language odyssey **
While I wouldn’t say I’m wicked adept at any one language, I’ve dipped my toes into many different languages. Here, I try to roughly recreate my programming language journey.

Gemini capsule
Gemini is a lightweight Internet protocol. It’s heavier than Gopher
but lighter than HTTP(S), especially if combined with all other web
technologies. The name makes sense if Gopher is Project Mercury and
the web is the Apollo program.
One of its uses is to serve gemtext, which is a lightweight
Markdown-like markup language, instead of HTML. Gemini browsers don’t
have support for neither Javascript, nor CSS, nor any of the other new
web technologies. It can be beautiful anyway, s … ⌘ Read more

humans have invented mathematics surprisingly early (while the status of the number zero was still being debated in ancient greece), and programming surprisingly late (although algorithms were around for a long time, they didn’t catch on until later, even though they seem like an at least equally intuitive concept?)

** What is an addressing mode? **
In a recent post I referenced addressing modes. But what the heck are they!?
The instruction register holds the program instruction that is currently being run.
A fixed number of bits within the instruction register represent the operation, e.g. “op. code” — examples of these instructions include things like add, subtract, load, and store. We can imagine the instruction register like this:

A .pbm file is the lowest common denominator among image file formats.

I feel like it took me a bit longer to fully understand how to work in Smalltalk than it did most languages.

Struct Tags with Underscore Before Function Names
In the Go world, an underscore (_) before an expression is called a blank identifier. As you may already know, identifiers—user-defined program components, e.g., name of a function, variable, or package—in Go must be preceded by an underscore or a letter (a-z or A-Z). If they aren’t, you’ll receive the compile- time error which essentially means Go cannot read the syntax of your code (you didn’t write your code correctly … ⌘ Read more
