What’s interesting here
 Which is the interesting thing about Mu is the dual runtime. So the above solution for Euler Problem 9 finds the solution in ~429ms with the Go VM and ~327ms natively compiled to darwin/arm64. Not bad for a language I haven’t really done any optimization work on yet (correctness first obviously).

Oh man wow 😼 Problem 9 was quite hard đŸ˜± I had to build two new functions in the Mu stdlib for computing combinations and permutations, but then the combinations of range(1000) for triples such as a + b == c is enormous! So i had to write iterator versions of these to do lazy evaluation. Anyway solution follows:

#!/usr/bin/env mu

// Special Pythagorean Triplet

import "iter"

fn usage() {
  print("Usage:", args()[0], "<n>")
}

fn sqr(x) { x * x }

fn main() {
  if len(args()) < 2 {
    usage()
    exit(1)
  }

  n := must(int(args()[1]))
  print("n:", n)

  // For a < b < c and a + b + c == n, both a and b are strictly less
  // than n/2. Generate only (a,b) combinations and derive c directly. This
  // keeps the search lazy and reduces n=1000 from C(999,3) = 165,668,499
  // candidate triples to C(499,2) = 124,251 candidate pairs.
  pairs := iter.combinations(iter.range(1, n / 2), 2)

  triples := iter.map(pairs, fn(xs) {
    a := xs[0]
    b := xs[1]
    return [a, b, n - a - b]
  })

  // Enforce b < c; a < b is already guaranteed by combinations over an
  // increasing range, and a + b + c == n holds by construction.
  triples = iter.filter(triples, fn(xs) {
    return xs[1] < xs[2]
  })

  // Euler 9 has one answer for n=1000. find() stops the entire upstream
  // iterator chain as soon as the first Pythagorean triple is found.
  answer := iter.find(triples, fn(xs) {
    return sqr(xs[0]) + sqr(xs[1]) == sqr(xs[2])
  })

  print(answer)

  if answer != nil {
    print(answer[0] * answer[1] * answer[2])
  }
}

main()

again: When it goes from item 9 to item 10, the indentation of the text (after the number) changes. Pretty ugly. In other words, a table of contents should be a table, not a list like it is at the moment. And that would require me to write my own extension for python-markdown 
 Probably not worth it.

I just wanted to look up 9V block battery prices online and these automatically generated descriptions are getting dumber by the minute:

Datum der Erzeugung: Verfallsdatum minus 7 Jahre

(Date of manufacturing: expiration date minus 7 years)

Or look at this one:

Die leistungsstarke 9 V-Block E Batterie, auch 6LR61 genannt, eignet sich besonders gut fĂŒr Taschenlampen, Radio oder Kinderspielzeug, die einen gleichbleibenden Strombedarf haben. Ihre max. Spannung betrĂ€gt 1,5 V.

(The high performance 9 V block E battery, also known as 6LR61, is particularly suitable for torches, radio or child’s toys, which have a steady power demand. Its max. voltage is 1.5 V.)

The battery is best suited for
 devices where it fits. No shit, Sherlock! Has anyboy ever come across 9V block torches? O_o I haven’t.

↳ In-reply-to » Day 9 also required some optimizations, if you aren't careful, you end up with really inefficient algorithms with time/memory complexity beyond what a typical machine has đŸ€Ł

@movq@www.uninformativ.de I shrank Day 9 Part 2 from “cover the whole map” to “only track the interesting lines.” By compressing coordinates to just the unique x/y breakpoints, the grid got tiny. I still flood-fill and do the corner-pair checks, but now on that compact grid with weighted prefix sums for instant rectangle checks. Result: far less RAM, way less CPU, same correct answer.

↳ In-reply-to » Advent of Code 2025 starts tomorrow. đŸ„łđŸŽ„

Day 2 was pretty tough on my old hardware. Part 1 originally took 16 minutes, then I got it down to 9 seconds – only to realize later that my solution abused some properties of my particular input. A correct solution will probably take about 30 seconds. đŸ«€

Part 2 took 29 minutes this morning. I wrote an optimized version but haven’t tested it yet. I hope it’ll be under a minute.

Python 1 feels really slow, even compared to Java 1. And these first puzzles weren’t even computationally intensive. We’ll see how far I’ll make it

Fark me đŸ€Šâ€â™‚ïž I woke up quite late today (after a long night helping/assisting with a Mainframe migration last night fork work) to abusive traffic and my alerts going off. The impact? My pod (twtxt.net) was being hammered by something at a request rate of 30 req/s (there are global rate limits in place, but still
). The culprit? Turned out to be a particular IP 43.134.51.191 and after looking into who own s that IP I discovered it was yet-another-bad-customer-or-whatever from Tencent, so that entire network (ASN) is now blocked from my Edge:

+# Who: Tentcent
+# Why: Bad Bots
+132203

Total damage?

Cascadia megathrust earthquake could trigger San Andreas fault
When the tectonic subduction zone beneath the Pacific Northwest moves, it does so in dramatic fashion.

Now, a new study in the Geosphere suggests the “really big one” could also trigger a major earthquake in California. ⌘ Read more
