I need to give a 60 minute "lecture" on ACID today .. not the fun kind and not the opposite of a base kind. Bleh! Hate doing this crap.

Nope .. Databases .. and it is stupid because everyone I am talking to should already know this (or they should be fired)

ACID (an acronymn for Atomicity Consistency Isolation Durability) is a concept that Database Professionals generally look for when evaluating databases and application architectures. For a reliable database all this four attributes should be achieved.

Atomicity is an all-or-none proposition.

Consistency guarantees that a transaction never leaves your database in a half-finished state.

Isolation keeps transactions separated from each other until they’re finished.

Durability guarantees that the database will keep track of pending changes in such a way that the server can recover from an abnormal termination.
 
I see now that I missed part of your quote ("not the opposite of a base kind"), so my joke was actually knocked down before I made it, but I learnt something. Hoorah!
 
Old Dimmu is amazing. Black Metal masterclass. But they have only lowered their quality in the last 15 years.

This song got me into them, maybe 4-5 years ago. One of my first favourite bands.
 
Mauna Kea .. is is not all that uncommon for them to drop below freezing. We lived in Hawaii briefly and it is odd that you can be on the beach and it will be 80, drive 20 minutes and be in the snow, while looking down at the beach with everyone sunning and swimming.
 
"Below" freezing?

When it freezes, it is already below zero. I know it's probably an abbreviation for freezing point but the one who made this one up didn't really bother about language and science.

Wow, all 50 states have at least one place below freezing (32 F, 0 C) today. That does not happen too often.

When it freezes it's at zero.
 
0 is the point where water freezes. Or 32 F. "Below freezing" indicates it's below that point for both scales. It's a useful phrase.
 
Only when we have pure fresh water with a pressure of 1013 hPa. This is an optimal situation that hardly occurs in nature.
Water that contains dissolved salts, like seawater freezes way later. The more salt, the lower the temperature before it freezes.

Fresh water -that is never entirely clean- also needs a freezing point that is a bit lower than 0,0 Celsius, e.g. -0.2. I am used to the saying "below zero" when it freezes. 0 I rather see as the melting point of water.
 
But is was still below freezing in all 50 states .. and I think it is safe to assume all the Provinces of Canada as well (not going to bother looking that one up) :)
 
I can assure you that it is. The only places right now where there'd be nowhere is...well, NS, NB, and PEI, and we're cold as balls.
