WaltPurvis··on In Maine, prisoners are thriving in remote jobs
The article says the software developer is making a six-figure salary and the prison system withholds 10%.
WaltPurvis··on In Maine, prisoners are thriving in remote jobs
>prisoners being coerced to work is payment for their crimes. On the other hand, that job would have gone to someone else at market rates. This kind of thing drags down the market rates.

That's a different problem, for different inmates -- the inmates covered in this story are paid market rates. It mentions the software developer has a six-figure salary.

WaltPurvis··on Oxford loses top 3 university ranking in the UK
MIT, Stanford, Harvard, Princeton, and I believe most or all of the other Ivies, all fund 100% of the demonstrated financial need of every student, and they do not consider the financial needs of applicants when making admission decisions.

WaltPurvis··on What Will China's Green-Tech Ambitions Cost the World?
http://archive.today/9FzGF

A really good article, although it's weird for the NYT to try so hard to frame the explosion of cheap green energy technology coming from China as somehow potentially nefarious or dangerous. Yes, China is prioritizing its own national interests as it exports green energy tech. And? It's still an overwhelmingly positive development for pretty much all of humanity.

WaltPurvis··on The dawn of the post-literate society – and the end of civilisation
The "point" the article is trying to make is that there is a decline in literacy so severe that it means "the end of civilization" -- a strong claim, to say the least, and one that demands rather stronger evidence than a 1-5% decline in various measures of literacy/thinking. (Granted, test scores are not the only evidence he has marshaled.)
WaltPurvis··on The dawn of the post-literate society – and the end of civilisation
I'm sympathetic to the concerns motivating this essay, but the charts related to test scores are ridiculous. The y-axis is so compressed it makes it look like performance has dramatically plummeted over the least 20-25 years, but the actual declines are basically 1-5%.
WaltPurvis··on A shift in developer culture is impacting innovation and creativity
This drives me crazy, too, but it seems like the misspelled version is now more common than the correct one. I imagine the dictionaries will eventually cave to common usage and say both versions are correct, and I'll remain bitter about it for the rest of my days.
WaltPurvis··on Aaron Levie: Startups win in the AI era [video]
>Altman was touring globally to raise $7T (yes, trillion), just a few months ago.

A few points about that: It wasn't just a few months ago, it was more than a year ago; he wasn't raising funds for OpenAI, it was for a separate chip-building venture; the $7T number was universally regarded as laughable, and the whole thing has predictably gone nowhere; and, FWIW, both OpenAI and Altman have publicly denied that he was ever trying to raise such a comical amount.

Authors are Eliezer Yudkowsky and Nate Soares.

The article is adapted from their forthcoming book, If Anyone Builds It, Everyone Dies.

WaltPurvis··on Betty Crocker broke recipes by shrinking boxes
This is an article about cake and cookie mixes. Nobody has to buy cake and cookie mixes; the article actually covers a woman who has stopped. And even for other kinds of packaged food, if people can't count on the brand names they're used to, they're more likely to explore other brands or generics, so the sales of one particular brand could very easily go down.

This article is seven years old; seems like (2018) should be in the title.
WaltPurvis··on E-paper display reaches the realm of LCD screens
It is fair for you to think I assumed the poster was a software developer, but in fact I looked him up before I made my comment and that is how he makes a living. (Unless something has changed recently.) I am genuinely curious how people (he's not the only one I know of) with such high sensitivity to LCD screens manage a career where staring at such screens for prolonged periods is the norm.
WaltPurvis··on E-paper display reaches the realm of LCD screens
>I can't use an LCD screen for more than 30 minutes without getting a headache

You're a software developer. How do you function? Do you spend pretty much your entire waking life with a headache?

WaltPurvis··on Three farmers on monopolies and mismanagement in U.S. agriculture
The article is not talking about people who own large tracts of farmland; it's talking about monopolies controlling the supply of seeds, chemicals, and fertilizers. At any rate, if Bill Gates owns 242,000 acres of farmland, that means he owns a bit less than three one-hundredths of one percent of the US's 880,000,000 acres of farmland.

WaltPurvis··on Just How Bad Would an AI Bubble Be?
>Business spending on AI is more than all consumer spending combined as a share of GDP.

Your phrasing there is misleading. The article says, "In the first half of this year, business spending on AI added more to GDP growth than all consumer spending combined," and the key is the "added more to GDP growth" part.

Growth in consumer spending was sluggish, while growth in business AI spending was insane, so in terms of how much the economy grew, the rise in AI spending exceeded the rise in consumer spending. Which is pretty amazing, actually. But, as far as the total amount of spending, business AI is at most only a few percentage points of GDP (and that's if you interpret "business AI spending" very broadly), while consumer spending is somewhere around 67-70% of GDP.

WaltPurvis··on Europe enters the exascale supercomputing league with Jupiter
Yes, but that fact does nothing to make the statement in question more sensible, so I don't know why you bothered to point it out, or to emphasize the "HPC6 [is] in Italy which is definitely in Europe" aspect. (Although I don't think the statement in question was all that nonsensical to begin with — IMO, it was just inartfully phrased.)
WaltPurvis··on Europe enters the exascale supercomputing league with Jupiter
Your Top 500 link says something completely different:

"The 65th edition of the TOP500 showed that the El Capitan system retains the No. 1 position. With El Capitan, Frontier, and Aurora, there are now 3 Exascale systems leading the TOP500. All three are installed at Department of Energy (DOE) laboratories in the United States."

HPC6 is listed below those, and far less powerful.

WaltPurvis··on Tesla offers mammoth $1T pay package to Musk, sets lofty targets
I believe Tesla bulls are banking on robots, robo-taxis, and other products. Surely nobody believes Tesla's consumer car business is poised to grow. (Given the history of under-delivering, etc., I wouldn't bet on Tesla dominating robotics or any other field, but as I understand it, this incentive package has no particular downside for shareholders.)
WaltPurvis··on Atny Mark Zuckerberg sues Meta for shutdowns for same name as Meta founder
I don't know of any front-end, but you can download the data in CSV or Excel format, and load it into a spreadsheet to search, sort, etc.

WaltPurvis··on Atny Mark Zuckerberg sues Meta for shutdowns for same name as Meta founder
>I would think it's probably actually a very common name.

It's not very common at all. The 2010 US Census reported 218 people with the surname of Zuckerberg. I assume no more than a handful of them also have the first name Mark.

WaltPurvis··on How to Give a Good Talk
Interesting. Do you just take one, shortly before your talk, or do you take it consistently, or what? I know a couple people who take propranolol every day to manage an elevated heart rate, but what kind of protocol do you follow?
WaltPurvis··on Amazon has mostly sat out the AI talent war
Originally bought it for an elderly parent in assisted living; wasn't as useful as we'd hoped; repurposed it as a kitchen-timer/music-box, for which it works adequately as long as the Internet connection is up. I would not recommend anyone else buy one.
WaltPurvis··on Amazon has mostly sat out the AI talent war
> Only thing it can do is set a timer, turn off a light

And it can't even do that without an Internet connection. As someone who experiences annoyingly frequent outages, it never ceases to boggle my mind that I have a $200 computer, with an 8" monitor and everything, that can't even understand "set a timer for 10 minutes" on its own.

WaltPurvis··on New research reveals longevity gains slowing, life expectancy of 100 unlikely
To be fair, the study authors explicitly say that their forecast only holds, “In the absence of any major breakthroughs that significantly extend human life," and, "The findings of this study are not intended to be interpreted as evidence in favor or against a biological age limit to human life."
