Today is the last day for a while my age will be a prime number - until 5 years and 1 day from now, to be exact. But the ages in between are still interesting in their own way, including a 3-smooth number, a square, and a cube.

For bonus points*, how old am I?

I'm reasonably certain the criterion given do not ambiguously specify the requested answer.

Pastebin'd to spoilerize (since the spoiler tag and code tag aren't compatible).

I had no idea if they would specify a particular pair of numbers, really. You did some good work! :banana:

[SPOILER]In the second pair of primes, 61 and 67, the 3-smooth number, square, and cube are all the same number: 64 = 2^6[/SPOILER]

Here are two ways you might resolve the ambiguity:
1. (side attack) [SPOILER]My user name had a literal truth to it when I created this account some years ago.[/SPOILER]
2. (mathematical) [SPOILER]There is a single semiprime between the two primes in question.[/SPOILER]

That is really encouraging. The the double-barrel medication sounds like a very effective approach.

Very best wishes to and for Phobos. Calmness Serenity Peace to you.

I can't quite parse the puzzle. Instead, I offer this-[INDENT]Three days hence my age will be a cube[SUP]2[/SUP]

[SPOILER]You'll be 64. A cube squared is n^6. Since you're neither a baby (1^6=1) nor Methuselah (3^6=729), you must be turning 2^6=64.[/SPOILER]

I know it was pretty obvious, but it is still kind of a cool number. Then there's the Beatles connection.....:smile:

Also, your explanation makes me smile.
I guess I could as well have said, "a square[SUP]3[/SUP]"

Today is Valentine's Day
 
If you haven't yet got your lover at least a card, you might want to get on that task pronto.

Got a GTX 580 back on line
 
This is my favorite MSI card. I had hoped that it had not given up the ghost.

Bizarre setup requirement: I have come to believe that heavy graphics cards can have a problem staying centered in the PCIe slot, when the motherboard is in the vertical position, as most are these days. I only got this card working again when I attached a support line (heavy shoe string) to the front-of-the-case end to keep it from sagging. This loops through a corner of a radiator fan.

Yes. I know this is weird. :cmd: It does work, however.

This card is running TF. I have been seriously looking at GTX 1060s to fill this role: Half the power, and considerably more throughput than the 580.

More weirdness: -d 0 and -d 1 are reversed for some reason. I have a 460 in the top PCIe slot, and the 580 in the second. However, the 460 starts from -d 1, and the 580 from -d 0. :confused2:

Today is also the [URL="http://www.computerhistory.org/tdih/February/14/"]computation day[/URL] (some communities celebrate it for a few years now, but some [URL="https://en.wikipedia.org/wiki/The_ENIAC_Day"]on the next day[/URL]).
