That's...your loss?

Why brag about ignoring a valuable indicator that applicants spend considerable time writing?

He has a concept playbook [1]. His MO is to tie current events back into the concept playbook. If you haven't been following along for a period of years, it is easy to get lost.

extra__tofu··on Zoom says it won’t encrypt free calls so it can work more with law enforcement
Whether or not you have a 'right to privacy' does not mean Zoom has to provide it. You can choose a provider who allows you to exercise that right.

Most things are still running, at least in my specific niche within the industry, because nearly everything is in Taiwan.

extra__tofu··on After 36 years as a paid product, the Micro-Cap Circuit Simulator is now free
Wow, used this extensively in my undergrad. Always used the free version. I remember occasionally running into the "too many nodes" error. Thanks to the creator for releasing the full version for free. I'm sure many EE undergrads will be grateful.

extra__tofu··on Tiny Books Fit in One Hand. Will They Change the Way We Read?
“A print-book!” It was hard to tell whether Dors was shocked or amused. “That’s from the Stone Age.”

“It’s certainly pre-Empire,” said Seldon, “but not entirely so. Have you ever seen a print-book?”

“Considering that I’m a historian? Of course, Hari.”

“Ah, but like this one?”

He handed over the Book and Dors, smiling, opened it–then turned to another page–then flipped the pages. “Its blank,” she said.

“It appears to be blank. The Mycogenians are stubbornly primitivistic, but not entirely so. They will keep to the essence of the primitive, but have no objection to using modern technology to modify it for convenience’s sake. Who knows?”

“Maybe so, Hari, but I don’t understand what you’re saying.”

“The pages aren’t blank, they’re covered with microprint. Here, give it back. If I press this little nubbin on the inner edge of the cover–Look!”

The page to which the book lay open was suddenly covered with lines of print that rolled slowly upward.

Seldon said, “You can adjust the rate of upward movement to match your reading speed by slightly twisting the nubbin one way or the other. When the lines of print reach their upward limit when you reach the bottom line, that is–they snap downward and turn off. You turn to the next page and continue.”

“Where does the energy come from that does all this?”

“It has an enclosed microfusion battery that lasts the life of the book.”

“Then when it runs down–”

“You discard the book, which you may be required to do even before it runs down, given wear and tear, and get another copy. You never replace the battery.”

   n=1, A=2:
   h    b   #tri  #non-congruent tri
   1    4   b-1   roundup(#tri/2)
   2    2   b-1   roundup(#tri/2)

   .
   .
   .
   
   n=4, A=16:
   h    b      #tri  #non-congruent tri
   1    2A/h   b-1   roundup(#tri/2)
   2    2A/h   b-1   roundup(#tri/2)
   4    ...    ...
   8    ...
   16   ...          ...
summing up #non-congruent tris for each n I see

   n  tri
   1  3
   2  7
   3  15
   4  31
so I think that answer may be 2^(n+1) - 1.

Could be wrong because I forgot what congruent really means.

extra__tofu··on Why Throwing 92 Heads in a Row is not Surprising [pdf]
If we are flipping a fair coin, the "surprise" we have at the result of any individual flip should be the same for all individual flips. Therefore, the entropy of the event, call it "A", of 92 fair coin tosses each resulting in heads is the same as the entropy of any other 92 fair coin tosses, "B". The sum of the individual event entropys must be the same so entropy(A) = entropy(B).

If you are talking about information theory entropy and saying a message of a billion bits composed of all "ones" has lower entropy than a "random" billion bit message, then sure. This is like saying we can compress the billion bits of ones and send less bits but the same amount of information. But I don't think this is synonymous with the above. It would be like saying for event A, each proceeding individual event has less entropy than the previous -- we aren't dealing with a fair coin anymore.

extra__tofu··on How to Read Mathematics
I believe sci-hub has been taken down, at least temporarily. The .cc and .bz domains weren't working for me. I think it's possible to setup custom DNS servers on your machine and access that way, but I haven't played around with it.
extra__tofu··on Clojure will affect the way you think about programming
I'm an EE who is getting more and more interested in software development and computation in general. I've been reading Paul Graham and Peter Norvig and decided to learn Scheme. Any thoughts on Scheme vs. Clojure for learning?
