Why do you think it's a code? It seems to me to be nothing but word salad. I haven't looked closely at one of his posts for a long time, but the last time I glanced at one it seemed to me that the choice of "nonsense" words was different from the usual, like the difference between a fruit salad and a chef's salad. All the salad words were from a distinct category, like musical terms or colors. (I can't find it now.)

His most recent posts seem to be of two types: short, more-or-less grammatical, meaningful statements, and the word salad sort: User: chrisowen.

I've noticed that his salad posts usually contain chess moves embedded in the salad. On one occasion I deleted the nonsense words and found that the chess moves, though unnumbered, amounted to a sensible alternative line of play. I commented on the line, and <chrisowen> responded -- in English! (Sorry, I can't link to that one either.)

But, "nothing but word salad" is too vague for me. I explained above why I don't think the example above was the product of a uniform random selection of words from a word list. And even if it was, how is he choosing the word list?

* How is the word list determined?

* How is the length of the message determined?

* In our example, there is one word with a much higher frequency than the others. It also comes with an optional prefix word. How are these special elements determined?

Note that all of the above are changing daily.

Wikipedia mentions several techniques:

<Word salad can be generated by a computer program for entertainment purposes by inserting randomly chosen words of the same type (nouns, adjectives, etc.) into template sentences with missing words, a game similar to Mad Libs. The video game company Maxis, in their seminal SimCity 2000, used this technique to create an in-game "newspaper" for entertainment; the columns were composed by taking a vague story-structure, and using randomization, inserted various nouns, adjectives, and verbs to generate seemingly unique stories.

Another way of generating meaningless text is mojibake, also called Buchstabensalat ("letter salad") in German, in which an assortment of seemingly random text is generated through character encoding incompatibility in which one set of characters are replaced by another, though the effect is more effective in languages where each character represents a word, such as Chinese.> Etc. https://en.wikipedia.org/wiki/Word_...

I get a lot of junk e-mail at the address I use for business purposes. I've noticed that when I look at some of the messages in the view panel (I never actually open them), I see word salad. Here is an example:

<His son quipped that power bars were nothing more than candy bars. He wasn't bitter that she had moved on but from the radish. The truth is that you pay for your lifestyle in hours. It was at that moment that he learned there are certain parts of the body that you should never Nair. If I don’t like something, I’ll stay away from it. Everyone was curious about the large white blimp that appeared overnight. She wanted a pet platypus but ended up getting a duck and a instead. She tilted her head back and let whip cream stream into her mouth while taking a bath.>

Some websites contain oodles of this stuff, usually on a page which is locatable by search engines but not hyperlinked to the home page of the site or any pages with real content.

The reason for this, as I understand it, is that some search engines will find this site more readily because if there's enough salad there they are likely to find a match to the search words among the salad words.

Here's another sample:

To my keen literary sensibility this reads differently from the previous example I posted, though still not very much like <chrisowen>'s work.

I'll make up an example. I'm using three unrelated articles that I looked at from the WaPo, the NYTimes, and The Guardian :

<Congress on Monday unveiled a 5,593-page spending bill and then voted on it several hours later, with lawmakers claiming urgent action was needed to rescue an ailing economy ravaged by the coronavirus pandemic.

But tucked in the bill was over $110 billion in tax breaks that strayed far from the way the bill was marketed to many Americans. These giveaways include big tax cuts for liquor producers, the motorsports entertainment sector and manufacturers of electric motorcycles. ...> https://www.washingtonpost.com/busi...

<Just as vaccines begin to offer hope for a path out of the pandemic, officials in Britain this past weekend sounded an urgent alarm about what they called a highly contagious new variant of the coronavirus circulating in England.

Here goes:

I could vary the flavor by using articles on different topics, or by choosing different pieces on the same topic.

Take out the (repeated) key move Qxg2+ and the other non-words and you'd have the sort of word salad that my program might conceivably generate.

Spoiler alert: Stop reading at the heading "Input", just after the warning

What operations can be performed on integers?

Let's see. There's addition, subtraction, and multiplication (regular and modular), factoring, rewriting in a different base, inverting the digits, adding up the digits, ...

Hmm.

The volume enclosed in the pie is V =πh r^2.

By letting t → 0, r and h can be made as large as desired, so V is unbounded.

The problem has an answer only if the crust of the finished pie has the same thickness as when you finished rolling, so the surface area is unchanged:

A = π(r^2 + 2rh).

Then h = (A/π − r^2 )/2r, so the volume of the finished pie is

V = πr^2 (A/π − r^2 )/2r = π(rA/π − r^3)/2.

Differentiating with respect to r yields

dV/dr = (A − 3πr^2)/2.

Setting this equal to 0 finds the value of r that maximizes V:

R = (A/3π)^(1/2).

The corresponding value of the height is

H = (A/π − R^2)/2R = (A/3π)^(1/2), so the volume is

If you number every foot clockwise on the edge of the table, starting with 1 in the corner you start; the ball will hit every odd number before ending up at the other odd numbered corner. That is half of the numbered places, but you need to disregard the starting and ending position.

I think what you've described is an outline of an acceptable proof, though it needs fleshing out. The observation that you can take m and n to have no common divisor other than 1 is key.

Here's my simple proof, likewise with some of the details a little hazy.

The case of m = n = 1 is trivial. Suppose m < n. Imagine an m x n box, with m units vertically and n horizontally, replicated endlessly upward and to the right. (If you want to test this argument with an example for any particular choice of m and n you can use a sheet of graph paper to sketch the boxes.)

Start at the lowest, leftmost point of this array, i.e., the bottom left corner of the first box. Draw a line at 45 degrees upward and to the right. Keep going until you hit a *top right* corner of one of the replicates.

This point will be p units above and p units to the right of your starting point, where p = mn, so you will have crossed p/m ‒ 1 boundaries in the vertical direction and p/n ‒ 1 boundaries in the horizontal direction. Each crossing corresponds to an impact with a cushion.

The total number of crossings is

p/m ‒ 1 + p/n ‒ 1 = n + m ‒ 2.

Of course the corner of the billiard table the ball eventually strikes isn't necessarily the upper right one, the one diagonally opposite the starting corner. All these replicates are copies of the table *reflected* about either a vertical or a horizontal axis, or both. You can predict which corner will ultimately be hit by keeping track of the reflections. For example, on a 4 x 7 table you cross six horizontal boundaries and three vertical ones. Since an even number of reflections produces the same result as no reflection, this is equivalent to one reflection about a vertical boundary and no reflections about a horizontal one, so the billiard ball will wind up at the upper left corner of the table. (Check it.)
