seems like a good one to know


var observer = new IntersectionObserver(function(entries) {
	var div = document.querySelector('.my-work');
	if(entries[0].isIntersecting === true)
	div.classList.add("visable");
	}, { threshold: [0] });
observer.observe(document.querySelector("#my-work"));

      This one surprised me. UNIX-y systems have cat(1), as many of us know:

      cat file.txt file2.txt > combined.txt

      I was surprised by this on Windows, though:

      copy *.csv combined.csv

      Did everyone else just know that and I'm only learning 20 years later? 😃

        I didn't know about that (or if I did I long forgot it); I use a port of cat on Windows.

        Today I learned

        $foo = 'hello world!';
        $foo = ucwords($foo);    
        echo $foo;

        Today I learned

        $a = [1, 2, 3];
        $b = [4, 5, 6];
        $c = [...$a, ...$b];
        
        var_dump($c);
        

        But that doesn't work if the arrays have string keys.

        Reminds me that yesterday I learned that in Ruby you can do:

        $ irb
        2.4.0 :001 > test = ['a', 'b', 'c', 'd']
         => ["a", "b", "c", "d"]
        2.4.0 :002 > test - ['c']
         => ["a", "b", "d"]

          Today I learnt e.preventDefault stops checkbox from being checked....why didn't I know that?

            TIL (okay, a couple days ago) that there is a json_agg() function in PostgreSQL.

            SELECT
              r.review_id,
              r.review_timestamp,
              json_agg(a.*) AS answers
            FROM $schema.review r
            INNER JOIN $schema.answer a ON a.review_id = r.review_id
            WHERE -- stuff
            GROUP BY review_id, review_timestamp

            Now I get just one row returned for each relevant review, and each row contains a JSON string with all the answers associated with that review. 🙂

              $schema.answer

              Not sure why my brain is expecting a ? or :schema.answer there

              We use Postgres's "schemas" to separate each client's data -- functionally similar to having them each in their own database, except they're not. 🙂 That query was actually extracted from the PHP code that builds the query (and simplified and anonymized here), so $schema would actually be replaced with the relevant schema name for the client being processed, e.g FROM client_foo.review r, and then processed with $pdo->prepare().

              This saddened me a bit. Watched "You Only Live Twice" and "Thunderball" this weekend in his honor. Wish I had a copy of "Robin and Marian", the chemistry he had with Audrey Hepburn was amazing. And I might be a fan indeed as I don't even hate Zardoz TOO much.

              Finally, pretty good compilation of the early Bond themes: https://youtu.be/J4jdUhxOz0M

              Zardoz is fun if not taken seriously. 🙂

              "The Man Who Would Be King" is pretty darned good. He and Michael Caine make a great pair in it.

              TIL that the film 'Lawrence of Arabia' had its world premiere 10 years closer to the start of the Great War than to the current day.
