This was my first time changing the oil on any vehicle. The biggest challenge was seeing and accessing the filter and drain plug and getting tools in there.

This can easily be done correctly using the conditional operator or “if” expression of many popular programming languages.

We’ve gone from “on premises” (correct) to “on premise” (stupid) to “your premise” (absurdly stupid).

And with minor changes, memoization.
![var cache = [Int: Bool]()
func canSum(sum: Int, candidates: [Int]) -> Bool {
if sum == 0 { return true }
if let cached = cache[sum] { return cached }
let result = candidates
.lazy
.filter { sum - $0 >= 0 }
.map { self.canSum(sum: sum - $0, candidates: candidates)}
.contains(true)
cache[sum] = result
return result

So easy to make a lazy stream in #Swiftlang. I’m loving this language.

I fired up Google Gemini Advanced and it offered me a new researching service. So I asked it to summarize what I have done with my 4th graders this year, based on our class web page: davebsoft.com/programming-...
The page never mentions Scratch! Here’s how it started.
(Much of the rest is correct.)

Gonna solve Advent of Code Day 1, Part 1 today in Snap! with my grades 4–8 students.
@jmoenig.bsky.social, I can’t find a simple way to sort a list of numbers in Snap!, so we’ll hand sort them.

I’ve written some interesting code for remote controlling a Cutebot, using two micro:bits and the radio feature. I’m planning to make a YouTube video showing and explaining the code.

I’ve been relying on the schools where I bring my computer science programs to provide computers for the students, but not all schools can do that. So I’m gradually building up my own pool of computers, including these three inexpensive android tablets that I picked up for $150 each.
