I had been on the fence about renewing my decade+ long Prime membership in a couple weeks. The only thing that was seriously tempting me to keep it was Prime Video.

I have mixed feelings already about Prime Video, as a watching experience I find it quite annoying because I'll find a movie I'd like to watch only to find I have to pay another $5 to watch it. With the other services, I know if a movie comes up on the display, I can watch it without further cost.

I'm fairly sensitive to adverts, I really don't like seeing them, largely because I've isolated myself from them. The fewer you see, the more unsettling they are, the blatant attractive factor of them, do.not.want. And anther $40/yr is too much.

Apparently, dropping Prime with the shopping really does not impact the speed of delivery or cost. I'm already often selecting delayed delivery. With the increased prices, it's hard to justify the $140/yr.

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.

ya, same, I don't know where I got this one but I modified it to include sticky

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 open the mug and rapidly cool the drink (eg dropping a few ice cubes in), heat should be flowing back into the drink?

(I mean that's not a crazy notion: if you have any warm mug and fill it with cold stuff, the warm mug will heat up your cold stuff.)

You are right that if you keep your mug closed, there shouldn't be any energy flowing back into your drink.

dmlerner · 2 years ago
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

Looks like a run of the mill aluminum air insulated mug. What’s special about this brand?
dmlerner · 2 years ago
In addition to the normal vaccuum insulation layer, it has a layer that does a (constant-temperature) phase change at ~140F. If your drink is hotter than this, energy flows out of the drink, cooling it and liquifying the layer. If you drink is cooler, energy flows into the drink, solidifying the layer.

I'd love to have a SQUID of my own to directly detect the |A| field that physics courses usually describe as "merely an abstraction" (Electromagnetic Vector Potential). I have some experiments I'd like to try.
dmlerner · 2 years ago
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`.

The garbage output signals get recycled indefinitely. Only the useful output ever needs to generate heat.

It was thought for some time that they needed be turned to heat, but that's actually untrue. Using quantum gates, it is possible to do an arbitrary classical computation and recycle the anciliary bits.

Blind post is no longer there.

Anyways, I didn't understand the acronyms so I decided to feed it to GPT and it definitely made it easier to understand:

Google is using a formula to determine which employees will be laid off (known as RIF: Reduction in Force)

The formula takes into account various factors such as location of labor (with US Premium Plus areas being more heavily impacted), tenure and performance in the current level, "runway" of compensation (the difference between base salary and maximum potential salary), and promo velocity (how quickly the employee has been promoted within the company)

This formula calculates a "number" for each employee based on these factors

Each Product Area Vice President (PA VP) is given a percentage of employees they must lay off

Employees with a score below a certain threshold, determined by the formula, will be laid off

Do we actually know a bit more on what people were let go, from what teams? Maybe the percentage of AI people in Google actually has grown relatively now?

And Google is in fact using AI almost everywhere in production already. You have some sort of AI in almost every product. Also language models are everywhere, e.g. just prediction of typing on your phone, or in GMail, in speech recognition, and many other places. I think they just do not use the biggest models for those things but some more efficient models, which can partly even run offline on your device (e.g. for the typing prediction).

Also in Google search, they use lots of AI, also neural networks.

It's just that for LaMDA specifically, they don't have a good product yet.

I find this plausible:

..........

> The formula looks at the variables below, and then spits out a "number" for every Googler. Each PA VP gets a % to cut, and as such there is a threshold. Anyone below that threshold gets RIF'd.

Variables are:

1) Location of labor. US Premium Plus was largely impacted versus cheaper areas. 2) Tenure and performance in level. 3) "Runway" of comp. (e.g. base salary vs MRP. eg. .8 of MRP Googlers have a long runway, vs 1.x of MRP Googlers are basically top of band, and 'tenured' with no runway except promo 4) Promo velocity

..........

I actually do have an (adult) ADHD diagnosis, though I've always been a bit sceptical of it. It seemed too easy to get and I really didn't think the testing criteria were very good.

I have wanted to try medicine to see if it helps me at all, but I've never been able to do so. My GP was willing to perscribe me something, but decided my BP was too high and that was that.

There are definitely anxiety issues at play as well, but I don't know to what degree.

dmlerner · 3 years ago
Combine with a blood pressure medicine? Guanfacine is specifically an ADHD treating blood pressure medication.
