<p>Right. Russia has been grinding for 50km in eastern Ukraine for 4 years, and now suddenly it wants to attack an alliance 7x its population and 20x its economy. It sounds like yet another excuse to erode liberty than an actual threat to the west.</p>

<p>i this context, "who cares" means "whose business". and the answer by the western society is that no ones but person in question.<p>bucketing ppl by birth year is literally a discrimination.</p>

<p>H/L/M - would be helpful (High/Low/Medium)
Escape as finish a game is pretty annoying (that's what you press after 'i')
f1/2/3.. would be nice to - go to the next number in the row
open all unflagged around current cell would be useful</p>

<p>Interestingly it has Thunderbolt 4 (40Gb), 6K typically saturates 30-31Gb, which leaves less 10Gb/s which isn't a lot especially assuming 2.5Gb network. Looks like a perfect case for TB5 and given its price.</p>

<p>actually it's quite the opposite: lectures are as approachable as one could possible make them, no fancy math and a walkthrough over attention is all you need</p>
