i dislike pressing shift, especially on non-ergo (non-thumb) keyboards where it uses my pinky.

Why not ripgrep?

I initially was going to cancel as well - I don't care that much about the fast shipping, and if you hit the minimum order, you get free shipping anyway. But, it means 3% back instead of 5% on the Amazon visa, so if you spend more than 150/12*50=625/month, prime is negative cost. Especially using it for many groceries, I usually hit that.

Can't live without this. The 10% of the time it doesn't work makes me sad. Super useful from cVim/Vimmium etc, I keep it mapped to 'gh'

If you rapidly cool the drink, you're definitely right - energy would flow PCM -> drink. Otherwise, it's semantic if GP is correct. There would be dynamic equilibrium, i.e. flow of thermal energy in both directions, but no true flow from PCM->drink.

The steps would be:

1) Drink > 140, PCM solid

2) energy flows drink -> PCM, drink cools toward 140, PCM liquifies gradually

Then two possibilities:

3a) drink cools to 140-epsilon before PCM liquifies fully

4a) PCM gives energy to drink in dynamic equilibrium, while also losing energy to environment, solidifying

5a) PCM is entirely solid at 140

6a) PCM drops below 140. drink gives energy to PCM and PCM to environment. drink -> PCM thermal conductivity is presumably much higher than PCM -> env, so drink and PCM remain at same temp

OR

3b) PCM liquifies fully before drink hits 140-epsilon

4b) drink and PCM stay at thermal equilibrium (see 6a) while cooling toward 140. energy flows drink -> PCM and PCM -> environment. The former is faster, so the PCM continues liquifying

5b) PCM is entirely liquid at 140. Due to thermal equilibrium, drink is also at 140.

6b) drink stays at 140 while PCM solidifies

7b) see 5a

8b) see 6a

You might enjoy the [Aharonov-Bohm effect](https://en.wikipedia.org/wiki/Aharonov%E2%80%93Bohm_effect). Quantum mechanics says we can in fact detect `A`. A similar effect exists for `phi`.

Combine with a blood pressure medicine? Guanfacine is specifically an ADHD treating blood pressure medication.

How are you not informed in advance? Every job I've had, there's a contract I sign in advance with all terms, and no addendum on day one. I'd think you could refuse to sign an addendum, and even sue for promissory estoppel if they fire you for not signing.

Admin just doesn't care that much which speakers are allowed on campus. Like many progressive things students loudly champion, it's pretty immaterial and easy to just give in. It's not like it affects MIT's status or funding as a world-leading research institute.

By contrast, Senior House was a significant legal liability due to large, public parties with a habit of sending people to the hospital for more interesting reasons than booze. That, the institute has financial, practical, concrete reasons to care about.

It's unclear to me that SH created more liability than frats and alcohol, but maybe, and it was certainly the perception.
