I'm gonna jump on a virtual happy hour Skype call tomorrow night myself.  Talking to a friend that moved to California and I haven't heard from in maybe a year.  And then my i s c & a aggie wife's birthday is Saturday, so it looks like I'll be falling off the wagon for a couple days.

The court that the wife practices in front of is dabbling in remote meetings. There's some constitutional issues there, but mostly there's societal and safety issues with not adjudicating or representing these clients in a timely manner. Some are Skype, some are zoom.

The daughter cleared out her dorm and came home last week. She's taking online class now (I'm having to review my "strong acid" knowledge). Of course, the boy is also home, but he's always running video.

They laughed when I put my million-packet-per-second router in place. They called me mad when I wired up the Ubiquiti AP.

Actually, they didn't. They really had no idea what any of that meant, nor did they care. They just griped when I had to down the network for 5 minutes to set it up.

Strong acids?  Interesting, there was a professor at Case Western named George Olah who played around with "super acids" that could protonate just about anything, like cyclohexane.  His research group apparently was 100% Indian.

One of the most dangerous acids is a fairly weak acid, HF, it does nasty things to your body.

Ive always been a fan of anti acids

especially after eating too much

My daughter is in her 2nd semester of General Chemistry. We're using the "common" definition of "strong acid". pKa values and such.

HF (regularly used to clean photomasks for IC etching - at least when I was younger) doesn't donate its proton aggressively enough to be a "strong" acid, but boy does that F- anion like to extract calcium from living tissue!

In the same way, anhydrous ammonia is a common enough substance. Farmers drive tanks of it around here all the time. If you're a form of life composed mostly of water, though, it's some of the most dangerous stuff on the planet!

Yup, in my first professional life I was final test engineer for ion implanters, and I'd occasionally have to work with the techs to clean photomasks from wafers we'd test-burned in my implanters.  HF will pass through your skin without affecting it much, but eats away at the bones once it reaches them.  Suffice to say the PPE for that job was extensive.

For source material during ion implantation, I also got to handle solid arsenic and phosphorous, as well as Arsine, Phosphine, Boron Triflouride and Silicon Tetraglouride gases.  All of which are very very nasty stuff.  SCBA was required for all of that handling.

The worst I ever read about is called fluoromethyl sulfate.  The story was that a post doc in Denmark got two drops on his lab coat, tore the coat off, jumped in the safety shower, and two hours later was dead of pulmonary edema.  Aldrich quit making it after that.  I never used it, though I used its cousin dimethyl sulfate, both potent methylating agents, kind of like how acids like to stick a hydrogen on something, these like to donate a CH3 group.

Often the useful reagents are highly reactive and thus tending to be very dangerous to humans.  I was not correct about Olah and superacids.  Memory is fading.

 George A. Olah prepared the so-called magic acid, so-named for its ability to attack hydrocarbons, by mixing antimony pentafluoride (SbF5) and fluorosulfonic acid (FSO3H).[4] The name was coined after a candle was placed in a sample of magic acid after a Christmas party. The candle dissolved, showing the ability of the acid to protonate alkanes, which under normal acidic conditions do not protonate to any extent.
At 140 °C (284 °F), FSO3H–SbF5 protonates methane to give the tertiary-butyl carbocation, a reaction that begins with the protonation of methane:[4]
CH4 + H+ → CH+
5
CH+
5
 → CH+
3
 + H2CH+
3
 + 3 CH4 → (CH3)3C+ + 3H2

I don't have a clue what any of you are talking about and I work for one of the largest Chemical Companies in the world....LOL.  But I do know how to make hydrocarbons!!

We use WebEx.  It works pretty good, but not near as effective as a face to face meeting once you get above about 3 people.  There is a cool video on youtube of the typical large conference video meeting, but I'm too lazy to look it up.  

Stay Safe, I hope football season isn't disrupted.

We once had a collaboration with Shell Chemical in Houston (Westhollow).  They had some amazing stuff there.  It was very neat what they could do with "streams" they called them, fractions from petroleum and NG, C1, C2, C3, C4, etc.  Hydrocarbons with so many carbon atoms.

Marcus,

Last week I bought a computer from a very large, Austin based manufacturer whose name contains 4 letters.  I'm very disappointed.  I bought it to replace my ~5-7 year old previous model (running Win 7) and I think it's as slow as the old one.  It seems to be bogged down by lots of bloatware, not the least of which is McAfee which is constantly putting up pop up boxes wanting to upgrade to this or that.  I wish they still came with a restore disk where I could wipe the whole thing and load a fresh copy of Win 10.

Sorry to hear that.  It definitely sounds like there's a problem, not even the bloatware should affect it THAT much.

If it's new, you should be able to restore via online.  But it'll still contain whatever software it originally came installed with.

Was this an Inspiron or something else?  DT or laptop?

First of all you can get rid of that Mcafee pop up by deleting an installed program which has nothing to do with running Mcafee

If youre not using Mcafee just uninstall any and all Mcafee programs

Second there are forums for Dell computers you might try looking at those for tips

Third you can buy a windows 10 program for about $100

Buy it install it and then go to the dell support sight for any drivers you need

just a thought

I have a five year old Dell Inspiron that runs Windows 10.  I've been very satisfied with it.

The wife bought an Apple because it was "easy to use" and discovered it isn't for her, and she's always running out of HD room.

My wife hates her Apple laptop, she finally gave up on it and made me buy her a Dell XPS.  Which is pretty much the sweetest notebook I've ever used.  Way slicker than my company-issued Latitude business-oriented model.
