rpearl··on The note Reddit sent to moderators threatening them if they don’t reopen
But that's not why the protest is happening...?
rpearl··on Buy well, buy once
I respect using that stuff for a while (my amp is about 12 years old but I'm upgrading this year).

Stick with what you have if it sounds good to you, but I do feel the need to point out two things: There have been significant improvements in room correction DSP algorithms particularly in the last decade. You don't need to ditch your amp to add these, there are DSP boxes you can put in the preamp stage. These will improve sound quality considerably. Audyssey, Dirac, and Anthem ARC are common names; there are others.

And there are a huge abundance of speakers in the mid range $200-$600 that are absolutely fantastic; it's a pretty wide market segment. There's plenty of old options too, but... it's not hard to find a new set of speakers capable of great sound at a decent price these days. I don't know what exactly Speakerbits was implying, but it's not true now.

If you've got enough keys that it matters you probably want to use a `Map` instead of an object? Maps are faster to write and read is approximately the same.
rpearl··on Software firms across US facing tax bills that threaten survival
No, fillibusters are a matter of procedure now. Nobody's standing up there talking to perform a fillibuster anymore.

From https://constitutioncenter.org/blog/filibustering-in-the-mod...

"When a Senator signals the intent to filibuster, an informal cloture process starts to determine if 60 votes exist to move a measure forward in two ways. One cloture vote is to approve a motion to consider a measure; the second vote is on the actual measure. If either cloture vote fails, the measure remains in limbo. "

The point of writing an essay is not to learn how to produce an essay. It's to learn analytical thinking, research, and argument skills.

rpearl··on Heat pumps of the 1800s are becoming the technology of the future
There are heat pump water heaters (I have one; AO Smith HPTU-50N). More expensive up front vs tankless but a lot more efficient.
rpearl··on What ChatGPT can't do
> the trick is to describe the algo in enough detail so that there is no room for misinterpretation

We could create a syntactically unambiguous form of textual representation of instructions.

We could call such a piece of text something specific, like a "program".

Your fundamental experiences as a human are already augmented by technologies so deeply integrated that our brains have changed to accommodate for them. For example: writing and speech.

What makes you think that "cyborg" means "foot replaced with hoverboard" and not things like "memory augmented with curated database" or "though process augmented with numeric-error-free calculation"?

rpearl··on My upgrade to 25 Gbit/s Fiber To The Home
Most of San Francisco can be served by Wave (cable). Sonic also has a large presence in San Francisco as well.

Over in Oakland I am paying $40/mo to Sonic for 10Gbps (though I only have equipment to route at 1Gbps at the moment)

rpearl··on Examining the covidtests.gov architecture
> antigen tests aren't going to show covid until a couple days after symptoms start (typically)

This is false? It was definitely false pre-Omicron and my understanding is that it's still false.

rpearl··on Stanford requires booster shots for all students
cool, cool. it's from HHMI and is a talk on multiple published works but okay. thanks for taking the time to process literally any of the information I am trying to communicate rather than just surface level cues from random words. it shows in the deep discussion you've provided us so far.
rpearl··on Stanford requires booster shots for all students
did you read the rest of my comment? or were you just keyword scanning? your question doesn't really follow from anything I said
rpearl··on Stanford requires booster shots for all students
> Boosters for last year’s virus makes less sense.

The antibodies elicited in response to the booster, 6 months later, are different and more diverse in their neutralization capabilities than the ones elicited in response to the first shots.

Although it is likely an omicron-tuned booster would be more effective, time is of the essence and there is both evidence and a reasonable explanation as to why the original booster works. Specifically, the immune system is not static and also changes over time.

Here is a presentation by a virologist on the research his team performed that leads to this conclusion (amongst other lines of research) https://www.youtube.com/watch?v=LIcaSqQFrX0

A software engineer is not paid to sit in front of a computer and that's only a small slice of the work.

rpearl··on How many real numbers exist? New proof moves closer to an answer
We did this first semester freshman year at my school in a single lecture in a 100 level "concepts of mathematics" course. I get that there's a certain amount of "it's hard to wrap your head around infinity" but really this proof is pretty well trodden by students not far into learning mathematics.
rpearl··on California exodus is a myth, UC research project finds
This very much disagrees with you: https://www.aaup.org/sites/default/files/AAUP-2021-SurveyApp...

A sampling of average overall salaries for professors:

- UC Berkeley (ie bay area): $214,300

- UCLA: $234,200

- UT San Antonio: $130,900

- UT Dallas: $169,500

So an average Berkeley professor makes more than half again as much as an average UT San Antonio professor. And 25% more than UT Dallas.

Studying nuclear engineering should be worthwhile. Studying power system engineering was.

Blockchains aren't.

rpearl··on Tracking the San Francisco Tech Exodus
The article they cite (https://www.sfchronicle.com/bayarea/article/People-are-leavi...) for claiming 10% of SF left is kind of misleading; 8 of the top 15 places they went to are _also_ in the bay area, and all but one was in California.

"SF residents move to Oakland and Berkeley" isn't a very exciting headline though

rpearl··on An NFT That Saves Lives
Because doing this as an NFT is utterly nonsensical. The NFT is involved for absolutely no reason. The only results of involving an NFT are (1) legitimizing a ridiculous scam and (2) causing extra environmental damage alongside the donation.

Just donate the money, using a fraction of the carbon cost, and if you want to generate hype, do a match.

What a waste of time and energy.

rpearl··on A majority of uninfected adults show pre-existing antibodies against SARS-CoV-2
In principal, viral vector vaccines are technically transmissible, though I do not think we have demonstrated actual transmission anywhere. The J&J vaccine is a viral vector vaccine.

The mRNA COVID vaccines are not; with those, the vaccine material is mRNA that your body codes into a protein recognizable to the immune system. The mRNA is both unstable (so it doesn't last long inside the body) and not capable of contagious transmission

There is open research, such as https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5777272/, as to whether making intentionally transmissible vaccines is feasible (or even a good idea)

rpearl··on Lets talk about changelogs (how I loathe 'bugfixes and performance improvements)
when we build a new feature, it's gated by a flag controlled by the server. The app version with the feature is distributed well in advance of the intended rollout. So, we can't even put the new feature in the change log for the update that includes the feature, and the rollout won't be associated with an app update.

All we can really put in the change log is bug fixes, and the circumstances that result in a bug can often be obscure and hard to describe in user-facing terms, so it gets summarized: "bug fixes and performance improvements". And for the play store and the app store, we have to put _something_.

rpearl··on Tech elites leaving San Francisco threaten Silicon Valley's supremacy
To be clear I (the original poster in this thread) have lived without a car in the bay area for almost a decade, and I don't Uber anywhere.

NYC is definitely more walkable--and just as expensive. Boston is about as walkable, I think (I haven't spent much time there)--and also pretty expensive!
