I'm curious on your response to GP's question. Have you heard of AHSME, AMC, or AIME? Nobody mentioned them in high school (1997) until I heard of them online and got my school to participate. 30 kids took the AHSME. Only one qual

This. The inconsistency of foul calls. I understand the mentality of "if you're not cheating, you're not trying" and "if you're not flopping, you're not trying", but it ruins the game for me. We shoul

This reminds me of a bug I created where the calendar showed only 30 days in March. I took the number of hours in the month, divided by 24, and rounded down. The bigger problem was that I couldn't replicate it because I was in Arizona

I was super happy with my Purism Librem 15 for 2 years. (Weird freezing issues after that. Replacing the memory didn't help. Maybe the mainboard went bad?) Have been tempted to try the Librem 14. I bought a Framework, but couldn't

Does anyone have a sleep/suspend configuration that isn't too difficult to configure and works well? I should update and try again, but as of 6 months ago, this was the one thing that made the Framework too painful for me to use a

I bought a Librem 15 before the 14 existed. I was very happy with it (including battery life/suspend) for about a year and used it with Linux as my daily driver. Then hardware started to fail and now it freezes randomly. (I've rep

A couple months ago, I tried to make a visualization video on Arrow's Theorem: https://youtu.be/Uvax1Hj8t_E I probably need to get my act together and do a final version of that video. If you're into this, then fe

Here's how I did it by hand (assuming you can buy multiple of a given item): Work in cents, modulo 87 (the cost of the cheapest item, the pinwheel). The total we want is 4394 (or 44 mod 87). Write down the price of every item modulo 87

Agree. Also, you could do the following things which Voice doesn't support: - Have multiple chats open (and be working on several responses) at the same time - Star chats (nice workflow for remembering to respond later) Although there

The code is mostly C#. There is also an Android app in Java. It is in the supply chain/warehouse management industry. I will email. Thanks!

Code128 has a mandatory checksum, so I'm surprised they try to do it with a font. Code39 is pretty common to convert into a font, since the checksum is optional.

The problem is that we need a way to say "actually; without exaggeration or inaccuracy" succinctly. Also, to say "I am using an idiom, but non-idiomatically." "Literally" should be that tool. I understand tha

The parent post said: > a third-party candidate doesn't spoil an election, because your second-place vote will still count. (E.g. Nader wouldn't have taken votes from Gore, so Gore would have won instead of Bush.) I was just tr

If Nader takes enough votes from Gore, then Gore will have the fewest first place votes and get eliminated first. Then Nader has to go up against Bush and it all comes down to who the Gore voters put as their second choice. It may only t

Maybe you're right. I know displaying in hex was way faster than displaying in decimal and seemed fast enough, so I stopped there. I didn't test rendering speed specifically. Doing a million digits in the console (with no status

Displaying hex is quite fast (compared to trying to display decimal), though you're right that it might add up to a noticeable amount of time in the end. I did the full million digit calculation on that sample page on the same compute

I didn't note timing numbers, but rendering digits in hex was basically instantaneous, even when doing a million (decimal) digits. Rendering the digits in decimal was significant delay (like 40 seconds for a million digits). That&#x27

It should take 415kB to store a million digit number, and the algorithm only needs to keep two of them. So, 1MB total to calculate a million digits of pi. I wonder if there are a lot of temporary allocations that build up until they get g

odds, not primes. And I'm sorry if it looks like 13 over 24. It's supposed to look like 1/2 times 3/4. (The next term adds 5/6, and so on.)

Yes, 4 * arctan(1) will do in any language. I just find some joy in knowing a formula that uses only addition, multiplication, and addition, and computing it directly.

Good question. I just presented it here the way it was given to me, as a couple initial terms and some rules on how it evolves, because I find that to be the easiest way to remember it. The actual formula looks much less friendly (because

It is interesting that the main photo on that article seems to be taken about 200 yards from where the Uber accident happened in Tempe, AZ.
