<p>That's a typo, I meant CPU!  I work with quantum computers, where we do discuss QPU (quantum processing unit) time, but that's not how I did this.</p>

<p>This is why I explicitly mentioned that in my puzzle ethics.  I reject that as a valid solve.<p>(And amusingly I said "qpu time" when I meant CPU)</p>

<p>I crushed wordle within a few days of its popularity entering my sphere.  It was pretty easy to brute-force a decision tree minimizing the average number of guesses using a lowly python script and a few days of qpu time.<p>Don't Wordle[1] is significantly more interesting; I've got a solver but the maximum score takes my lowly python script upwards of a day (per day) to solve using brute force.  For now, I solve it with a heuristic that terminates in about 20 minutes.  My old wordle solver was useful to find a good but suboptimal tree for identifying the answer in 5 undos or less.<p>Today:<p><pre><code>  Don't Wordle 1491 - SURVIVED
  Hooray! I didn't Wordle today!
  ..... 8089
  ..... 4647
  ..... 2492
  ..... 1026
  .Y... 231
  ..G.. 100
  Undos used: 3

    100 words remaining
  x 10 unused letters
  = 1000 total score
</code></pre>
My puzzle ethics are: you can and should download the dictionaries of valid answers and valid guesses, you're allowed to keep them separate, but you must not keep the list of answers in its original order.<p>[1] <a href="https://dontwordle.com/" rel="nofollow">https://dontwordle.com/</a></p>

<p>A great many real world problems have, at their crux, a mathematical problem.  A mathematician paired with a subject matter expert can be powerful indeed when each sees deeply into the others' blind spots.  But, I've heard statements like yours a lot over the years: assuming mathematicians aren't fully aware of the limitations of what you think math is.</p>

<p>If you're going to strike up conversation with strangers, it's best if you <i>make it easy for them</i>.  If you're asking for a joke, you're making it easy on yourself and setting a bar for them.  I'm a jokester but I don't have a good repertoire of jokes on hand -- I respond to banter.  So if you ask me if I have a joke, I often just sputter and throw out the last bad pun somebody shared with me.<p>Make a joke yourself, if you're feeling funny.  But be warned... a stranger once asked me why I was going on a trip.  I was visiting my dad who was presently in surgery for cancer that would go on to end his life.  I was too emotional to answer with anything but the truth.  I certainly wasn't going to respond well to humor.</p>

<p>> What does it say about progress that the same laws that protect human rights also stifle innovation?<p>Innovative methods to destroy human life are "stifled" by measures intended to preserve human life.  What to you mean by "progress" -- the betterment of the human condition, or the enrichment of the few and powerful?</p>

<p>If anybody has ever tried folding a very large paper (or, bedsheets, tarps, etc), they'll realize the wisdom of this comment.  Our intuition from folding paper on the order of several to tens of centimetres does not scale to arbitrary size and precision.  Paper is relatively rigid, but its rigidity is finite and ensuring local-to-global flatness becomes a painstaking endeavour.</p>

<p>I had the same thought -- with a checkerboard pattern of 1:1:2 "brick" voids where each brick would be surrounded by bricks of a differing offset, one could conceivably calibrate the injection step and the print might have less propensity to cleave along xy planes.  But, given the complexity of that calibration (and need for a high-flow head) I'd rather use the brick infill available today.</p>

<p>Teachers in public schools are being told to use AI in their curriculum.  In some cases, this means students are being taught not to think (regardless of the intent of the lesson).  When prices make this curriculum untenable but the kids already depend on it, that rugpull is going to severely harm a generation of kids whose education was already disturbed in 2020.</p>
