twojacobtwo··on AI helps researchers dig through old maps to find lost oil and gas wells
I think the parent post was referring to the anti-environmentalist aspect of the new administration. They're not going fund remediation efforts while attempting to dismantle the EPA.
twojacobtwo··on Show HN: Voice-Pro – AI Voice Cloning
I'm legitimately wondering what you recommend from among those options.
twojacobtwo··on The new climate math on hurricanes
No one has time to verify/double check literally everything they're told. And if they did, they wouldn't have the time to learn everything that one would need to know to verify everything. It's impossible. Therefore, some level of trust is necessary: moreso for those who have less time/opportunity to learn and verify.

While I understand the sentiment, blaming ~everyone~ provides no value here, while blaming the institutions who actively misled the world might.

Sounds like personal experience -> project motivation.
twojacobtwo··on IronCalc – Open-Source Spreadsheet Engine
Sweet, it's basically data on HN users then.

Only 13.4% of HN readers use Firefox. For shame. But seriously, it's interesting that safari is top by quite a margin.

twojacobtwo··on Universal optimality of Dijkstra via beyond-worst-case heaps
Several other commenters have now pointed out the differentiations, in case you weren't aware.

I always saw those as parameters for some reason. Transmit(x), Receive(x).
twojacobtwo··on Microsoft Recall is now an explorer.exe dependency
Are you sure? Is this recent (last 6 months)? I enabled it and tested multiple versions of Proton with no success. Did you have to do anything else?
twojacobtwo··on Microsoft Recall is now an explorer.exe dependency
I wouldn't say always. The last time I ran such a script, it didnt break anything. Granted, I did as the repo readme expressly and boldy stated, more than once, that 'anyone using this should read through the list of commands' (it was also nicely commented for lay people) and disable any sections related to services they use. Regardless, the defaults seemed quite sane and I even had to enable/uncomment a few for other services/products I didn't need.
twojacobtwo··on An adult fruit fly brain has been mapped
Isn't that just saying "if you take the cube root of the number, it's a smaller number"?

I don't mean to be facetious - I'm struggling to to see what other consideration this helps with.

twojacobtwo··on DoNotPay has to pay $193K for falsely touting untested AI lawyer, FTC says
It's a matter of opportunity costs as well. If you want to be able to do plumbing, wiring, framing... you likely don't also have the time to learn the potentially vast amount of knowledge required to adeptly navigate the legal system.

> Some people are really woried about making big mistakes that are expensive to clean when plumbing or wiring or lawyering.

Even worse, if you lawyer wrong (or wire wrong), you might not be able to clean it up - you just do your time or perhaps die.

twojacobtwo··on Who is Marcellus Williams: Execution in Missouri despite evidence of innocence
> When the parties are present for cross examination it's not hearsay.

That's exactly what I just said.

twojacobtwo··on Who is Marcellus Williams: Execution in Missouri despite evidence of innocence
Here's a more thorough definition:

> Evidence that is not within the personal knowledge of a witness, such as testimony regarding statements made by someone other than the witness, and that therefore may be inadmissible to establish the truth of a particular contention because the accuracy of the evidence cannot be verified through cross-examination.

Tying the two together, basically it would be anything that can't be verified (in court) by the one who the witness is 'quoting'.

Regarding witness testimony, I don't think the tradition of it makes it any more iron clad. We used to have a lot more testimony of sorcery and such as well that got people killed. Further, we have only recently begun to study it scientifically. From what I gather, from my very limited knowledge of the studies thus far, it doesn't look good for eye-witness accuracy in general.

twojacobtwo··on Finish Your Projects
It's a little much to say almost everyone does it wrong. More likely, since it's something that catches your notice, you probably have a bias for noticing/remembering when it's incorrect and not noticing when it's correct. It could also just be a simple typo or an autocorrect error for any given occasion
twojacobtwo··on Bitcoin Mining Shutdown Cause 20% Surge in Electricity Bills
That was one of my first thoughts as well. The article sells this increase as a necessity, but with no note of whether that was to maintain profits or operating costs, further research may be required. My feeling is that it's the former though.
twojacobtwo··on Bitcoin Mining Shutdown Cause 20% Surge in Electricity Bills
Interestingly, in the list of other articles at the bottom of the page was the previous entry in this story:

> Noise Complaints May Cause Norwegian Bitcoin Mining Center to Shut Down

From August, 2018! The earlier article also states that they were operating without permits for over a year by the time of that article. Sounds like the town has offered incredible patience.

Further:

> Many of the area’s residents have been forced to evacuate bedrooms close to the venture’s primary facility and keep their windows shut throughout the day, even during the summer’s rising temperatures.

After 7 years of that, I think I would opt for the 20% increase in my electric bill as well.

twojacobtwo··on How to succeed in MrBeast production (Leaked PDF)
> I think you grossly overestimate HN's prominence in the tech industry. It was where all the founders hung out 15 years ago. It's now just a place where IT workers talk.

You either missed the point of the GP comment, or you think that it's entirely pointless to discuss important issues unless it's with people of prominence. Depressing if it's the latter, but given how you started your post, I'm leaning toward that interpretation. That's some kind of fucked up elitism right there.

twojacobtwo··on Ask HN: If LLMs are so useful, why haven't we seen any spike in productivity?
Profits? I mean, I'm guessing the trend can't be wholly disconnected from the massive layoffs in the tech sector over the last year or so. Probably not the primary driver, but companies are always looking to maximize profits and, in the short-term, what faster way is there than by making cuts?

If a business sees a 15% productivity boost coming, especially with no easy plan in place to to utilize it fully for equivalent profit, someone near the top is already thinking that quick cuts could be an immediate 15% increase in reported profits for next quarter (in a 1:1 scenario).

I'm being a bit simplistic, but I think the general idea of business maximizing profits over output stands (or easy short-term thinking over more difficult long-term planning).

twojacobtwo··on How on-the-wrist sleep apnea detection works
I think this depends on your doctor/clinic and where you are. The last one I took home just had an oxygen sensor and the skin probe/patch. The doctor said they get (hand wavey) 95%+ of the same diagnostic capability from the simpler setup and far fewer claims of poor quality sleep caused by the equipment.
twojacobtwo··on 20% more powerful perovskite solar panels enter commercial use
Relevant details:

>The 72-cell panels, comprised of Oxford PV’s proprietary perovskite-on-silicon solar cells, can produce up to 20% more energy than a standard silicon panel. They will be used in a utility-scale installation

>Oxford PV has been developing and working to commercialise this technology since 2014, with a recent module efficiency record of 26.9%.

twojacobtwo··on Tire-related chemical responsible for salmon deaths in urban streams (2020)
For those wondering what the chemical is and its purpose:

>6PPD helps by reacting with ozone before it can react with the tire rubber, sparing the tires.

>But when 6PPD reacts with ozone, the researchers found that it was transformed into multiple chemicals, including 6PPD-quinone (pronounced “kwih-known”), the toxic chemical that is responsible for killing the salmon.

twojacobtwo··on Death Rates by Vehicle Model
I was just about to ask the same question. My initial thought was that perhaps they all have small crumple zones, which would increase the overall force applied to everyone involved.

I looked up images of the vehicles you mentioned and they all seem to have a relatively aggressive slope on their front ends, which got me thinking that they may end up acting like a sort of ramp in a collision and cause the other vehicle to become airborne or roll over.

twojacobtwo··on 2M users but no money in the bank
Non-profit simply tells people what the incentives/motivations are or are not.

The average for-profit company can't be trusted/expected to do what's best for anyone outside the profit structure (e.g. users or the public at large). Of course you can have exceptions in either direction, but on average for-profit orgs will likely be willing to fuck over anyone else to increase profits - intentionally or not - because profit growth is literally their purpose.

'Non-profit' advertises that you don't have to worry about that specific, powerful motivation of the org contending with your best interests.

twojacobtwo··on Amazon bans its drivers from moving their own lips too much at work
Does what's considered normal matter for safety? Shouldnt it be based on what the science says?
twojacobtwo··on Kim Dotcom's extradition to the U.S. given green light by New Zealand
This is why definition of terms is so important in discussions of this type. The word socialism/socialist has been bastardized and propagandized beyond comprehension now. Socialism covers a broad range of potential policies and structures, but in modern discourse the average person seems to slot it in almost exclusively to mean government tyranny and communism. Meanwhile communism now seems to mean evil beyond any consideration.
twojacobtwo··on Kim Dotcom's extradition to the U.S. given green light by New Zealand
Do you mean back to FDR-era policies, or are you using socialism as a stand in for the tyrannical communist governments of USSR et al?
twojacobtwo··on A wonderful coincidence or an expected connection: why π² ≈ g
> since reality is definable as that which is independent of measurement.

In terms of quantum mechanics, would that mean the wave function is real until it collapses due to measurement? Or am I misunderstanding your use of measurement there?

Something about that is sticking in my mind in an odd way, but I can't put my finger on exactly what it is - which is intriguing.

twojacobtwo··on Open Source Farming Robot
Nor are we perfect and we've been wrong about much in nature more often than we've been right over the past many millennia. The previous poster didn't imply either case regardless. The post simply pointed out an assumption being made.

Frankly, I prefer the way that thinks of 'ex post facto' explanations for nature. At least that keeps us hypothesizing and not sitting there tooting our own horns.

twojacobtwo··on Hundred Rabbits is a small collective exploring the failability of modern tech
I believe duckduckgo offers a similar warning when playing videos from search results.
twojacobtwo··on Creativity fundamentally comes from memorization?
That seems like a much more recent and much smaller phenomenon. The censorship and attempted or succesful modification of school curricula (esp. evolution/biology and sex education) by 'right wing' christian groups goes back many decades across much of the southern US.
