Pretty much the only way I get things to *stay* in my head is to do them, and then document what I did. Task one: Doing the Multithreaded Server Exercise from the book. Yesterday, I ripped through the Rust “Writing a multithreaded web server” exercise, as I don’t have much experience with writing network code […]

In my quest to become the world’s greatest programmer, I have been informed that I must reboot my React and Django skills. What better way to make that happen than to port my Boggle solver program to the web? It’s not good enough to shell out to boggle-solve and just make things happen. I wanted […]

I have a job interview this week and one thing they wanted me to know was that they were into Uncle Bob, “Clean code,” and test driven development. They were really, really emphatic about Uncle Bob’s “Transformation Priority Premise,” his notion that you start with failing (broken) code that does nothing, then does one thing, […]

Boggling 2: Parallelized Boogaloo! When last we left our heroes, they’d solved Boggle! and done so with amazing speed. The only thing left to do was go faster. There are two strategies, actually, for going faster. The first, mind-bogglingly enough, is to go the other way with your search space: building a graph of the […]

All right, so now I’ve got a bitmap for tracking the path I’ve taken on the board, and I’ve got a trie that can determine whether or not a sequence of letters is a word (or the prefix of a word) from a specified dictionary. Let’s solve Boggle™. A Boggle board is a 4×4 grid […]

One of the things I needed in my Boggle solver was a bitmap. The average Boggle! board is 4×4, or 16 squares, and one of the rules is that you may not use the same letter twice. I needed a data structure that would handle the "Have I seen this before?" Now, for a 4×4 […]

There was a research project named Wyvern (not related to the current programming language Wyvern) that was intended to invent what would probably be called a "lexically scoped paradigmatic programming language." Programming languages are built on paradigms. In programming language theory, a "paradigm" is a set of ideas that form a mutually exclusive way of […]

Data Structures: Tries in Rust

Posted by Elf Sternberg as Uncategorized

I recently went to a job interview (I’m looking for work, by the way; hire me!) and one of the questions put to me was “solve the Boggle™ board.” I don’t think I did very well on the question and it wasn’t until I got home that I remembered “Dammit, the fastest structure for checking […]

“But what are they for?”

Posted by Elf Sternberg as Uncategorized

“But what are they for?” Do you remember the days in pre-college when you were taking geometry, or algebra, or calculus, and wondering when in your long and varied life you would ever have a need to use the quadratic equation? I remember having that thought lots of time. I had that thought once more, […]

Tech Republic has an article entitled Top priorities for professional developers: Why devs are always looking to learn new programming languages. It’s not until the bottom of the article that we get to any mention of programming languages versus programming skills in general. General skills are about things other than languages: Kubernetes and AWS are […]
