THIS IS YOUR REMINDER
That you are awesome.
Every problem you've ever had, you've found ways to get over, around, thru, under, one way or another you've dealt with it or are currently dealing with it, and there's no reason to believe you can't or won't continue to do so into the future.
And that's awesome.
You're awesome.
Greetings. Once upon a time long ago, I was sitting alone in the UCLA ARPANET site #1 computer room late one night when the high Santa Ana winds outside started disrupting power. Hit after hit, very dangerous for the minicomputers, disk drives, and other equipment in that room, since we didn't have uninterruptible power supplies back then.
I made some calls and it was decided I should shut everything in the room down. Everything. I phoned the ARPANET NOC (Network Operations Center) at BBN and explained the situation, since I was about to shut down IMP #1 (essentially, a refrigerator-sized router) on ARPANET which sat in a corner of the room, and doing this could cause disruptions if done in an unplanned manner. The IMP was *always* running -- I had never seen it powered down.
I worked my way around the room, powering down terminals and disks, and printers, and the power supplies on the 11/45 (ARPANET Host #1 - UCLA-ATS) and the 11/70 (Host #129 [1+128 on IMP #1] - UCLA-SECURITY. Back then my email addresses were LAUREN@UCLA-ATS and LAUREN@UCLA-SECURITY -- no domains yet.
The usual roar of the machines gradually got quieter and quieter, until only the IMP was left. I pulled down the power switch. Now there was dead quiet except the hum of the lights, a situation I'd never experienced in that room before. Very odd feeling.
Suddenly I heard a click -- the IMP was powering back up by itself. Damn. I pulled down the switch again. Quiet for a time, then click and it came back up yet again. Before I started thinking about screwing around with its power cables or turning off breakers that could have unexpected effects, I called the NOC again to ask them if they had any ideas.
"Oh yeah. We should have told you! There's a little switch that controls auto-restart. Surprise!"
So I found and flipped that little toggle switch, powered down the IMP again, and this time it stayed down. I had turned off the ARPANET -- at least at UCLA. -L
@futurebird @Gbudd I’m a recovering Jet Pens addict. They do have some fancier stuff too. I was all up in the bujo and sketchnotes supplies. I started shopping local when I lived in DC and found great stores there. Check https://fahrneyspens.com
"It’s very often the case that when a man puts work out into the world, the world looks at the work and says, 'Is this work worthy?' And I think that when a woman puts work out into the world, the world looks at the woman and says, 'Is this woman worthy of putting out work?'" - Glennon Doyle
YUP.
(And I would add, and I expect Glennon would fully agree, that the same "are they worthy?" question is applied when the person putting work out is queer or a person of color.)
@futurebird That’s a great list! Thanks so much for pulling it together! I’m bookmarking it now.
@brndnpink @futurebird It’s probably not a great pen, but I picked up a Pilot pen the other month and I enjoy it for daily use (it runs ~ $24 on Amazon).
@futurebird, is there a good online source you like for pens?

@futurebird @JorgeStolfi I like “rubber ducking” when I’m debugging something mysterious. I’ll explain it to the rubber duck on top of the monitor (or the dog (the cat loses interest)) and that helps me get it
This is the kind of confidence you build by getting that thread back again after you've lost it a few times.
Only started to get there towards the end of grad school. Now I know that if I read some math & don't get it I'll just memorize the definitions & put it away. Come back later. Read it again. Still not there? Memorize theorems. Put it away. Come back. Still not there? Explain it to my husband or cat. (rarely gets this bad)
But this works every time.
If you're a space nerd, especially an Apollo-program nerd, drop whatever you are doing and watch this awesome video with Luke Talley.
He was an engineer for the Saturn V's IU. He explains the entire launch process.
It is AMAZING

I’m willing to be wrong, certainty often means that I don’t actually understand the problem
