"Clique" is a small close group of people, "cliché" is an oft-repeated observation.
RobGR··on This I Believe (1952)
Between this https://thisibelieve.org/essay/16630/ and https://www.awakin.org/v2/read/view.php?tid=468 there are additional paragraph breaks, which might be attributable to it being transcribed from audio; the first link has an audio recording, the second link does not. In one a pause is transcribed as "-" and in the other as comma.

However, the second awakin.org version is also missing a piece of text:

"I believe in Rodger Young. You and I are free today because of endless unnamed heroes from Valley Forge to the Yalu River. I believe in—I am proud to belong to—the United States. Despite shortcomings—from lynchings, to bad faith in high places—our nation has had the most decent and kindly internal practices and foreign policies to be found anywhere in history."

I had to google Rodger Young: https://en.wikipedia.org/wiki/Rodger_Young

RobGR··on The Book of Debugging
This looks like a good book. I've always liked https://debuggingrules.com/ . I'll probably preorder this.
RobGR··on Keyboard differences between Windows and Macs
A school teacher at a small charter school, teaching various levels of math and a few foreign languages. This person was pretty technically proficient - they used a linux to access the web, but it was set up to boot a browser in to full-screen kiosk mode, and they pretty much just searched webpages and printed things out sometimes, no email really.

The DOS was DRDOS 7.22, and it was very elaborately set up -- it boots from a CDROM or USB flash disk as a live disk. On the disk is every assignment, homework, or test for any of the various courses he taught, carefully organized. They are in WordPerfect 5.1 with a few graphics in another program, and a graphing ( as in X-Y cartesian plots ) program also, all ancient freeware DOS. The three programs come up instantly on boot in different terminate-and-stay-resident screens, that you switch to with a control-alt combo, very like switching terminals in text mode linux.

This meant he could take a CDROM to school, pop it in the horibly slow and ad-laden windows computer some government program had given the school for free, boot, disconnect the printer from the network to the constarnation of other teachers and plug in a USB cable, and print his assignments, and never bring back viruses. The students when they learned of this situation would search out old viruses on the web and try to infect everything.

But using windows and mac was pretty limited to a little bit of browsing, and occasionally going to a dedicated machine with the right program already set up, to enter grades and time sheets and etc.

RobGR··on Keyboard differences between Windows and Macs
They were familar with a mouse from DOS based drawing and diagram programs. Most of those did not have keyboard and mouse input active at once, you were using the mouse, or you were in a different mode to enter text. Some of them had one pointer, so you could be typing, bump the mouse, and put characters in the wrong place.

The tabs in question covered modern Firedox, xfce4-notes-plugin, and I think gedit. It was the concept of tabs, not the appearance. None of them looked that much like the tab on a manilla file folder.
RobGR··on Keyboard differences between Windows and Macs
This is a really interesting and complete writeup.

I have been helping someone who has little experience with Windows or Mac, but used DOS for years ( until pretty recently ) and I've set them up with a simple Debian Linux running XFCE4 as the desktop. I've found that I have to teach them and also document a lot of basic computer idioms -- Control-C / X / A / V to copy, cut, select all, paste; but also more basic things, like the fact there are two pointers on the screen -- one for the mouse and one for the keyboard -- if you slide the mouse pointer to a specific point and press a keyboard key, the new key will not appear where the arrow is, it will appear where the text cursor is.

A big one was tabs. I had to get a couple of manilla folders and show them the actual tabs, and hold it up next to the browser with several tabs, and suddenly it snapped with them what the interface was trying to represent.

Control-A will select all of a web page, unless you are in the text entry box of a form, then it selects just the things in that text entry box.

I started writing this up in a little manual, it got to a dozen pages fast, and I haven't put very much in it.

If anyone knows of a place where some portion of all of this is written down, post a link !

I live near the Dell's Favorite olive oil farm, was happy to see them in this article.
RobGR··on SynthID Detector
If I go directly to the URL it wants me to agree to some stuff before I even know what the service is. I had to come to these comments to figure that out (without agreeing to anything first).
RobGR··on Ask HN: Do you still own a printer?
Yes, I maintain two at different locations and am often asked by printerless friends if they can use them. Most use is bureaucratic stuff like forms for various licenses and permits and etc, but I have a manual on the use of a particular bit of software that I am writing, I find it nice to print that out and make marks in the margins for later editing.

I'll get an Epson EcoTank color printer as my next one, and maybe the https://www.crowdsupply.com/open-tools/openprinter if it ever comes out and is really open. I also would not mind a decent receipt printer. I forgot that I own a couple of Dymo label printers too, and wrote some driver software for them years and years ago. But free printers that have enough ink or toner to last a while are pretty common.

Not having a printer is like only having a phone and not a laptop. It labels you as a consumer and recipient of culture and society, instead of a participant.

RobGR··on I quit OpenAI because its culture is broken
Yes, both sides are working on a presumption, with no evidence except playing out a thought experiment that is heavily biased by our own outlook.

However, when proposing that someone be stopped from doing something, the burden of proof is on the proposer.

RobGR··on I quit OpenAI because its culture is broken
Exactly, it will have the goals of the humans who control it, just as the first pointed stick we made pokes what we jam it into.
RobGR··on I quit OpenAI because its culture is broken
That's just applying Pascal's wager, and you can argue for or against any action that way if some fanciful extreme hypothesis of infinite harm is treated as serious.
RobGR··on I quit OpenAI because its culture is broken
There is no reason to presume a superintelligence we build will want pets, feel antipathy to humans, or be god-like in any way, or even have any goals other than what we give it. If you jump to this conclusion, regardless of how many big words on less-wrong you attach to it, this speaks only about you and not about AI. If you think the super-AI will hate humans, it's because deep inside you hate humans. I also hate humans, but I know that humans are making the AI, it probably will not hate them, in addition to surpassing me in other abilities.

In general, the smarter a person is, the nicer and more helpful they are. There is no reason to presume differently of AI, especially if we are building it to be helpful to ourselves.

RobGR··on I quit OpenAI because its culture is broken
Because they still have stock in the companies, and in a larger sense, are very personally invested in AI being big and important as possible.
RobGR··on Moist-Electric Wallpaper for Indoor Energy Harvesting and Humidity Management
When these systems are designed for low ambient humidity areas, they use a desiccant based first stage, where desiccant wheel or loop captures water from the low humidity air, and then is heated in a chamber to "regenerate" it and drive off the water into a 100% humidity chamber where the condensation can happen.

The applications of condensate water sources typically aren't in areas where desalination is the competing technology -- usually the competition is piping water in from far away via a utility system.

RobGR··on Moist-Electric Wallpaper for Indoor Energy Harvesting and Humidity Management
If it's for watering plants it works fine, if you want to store it and use it otherwise you need a filter and UV sterilization, many of these devices also mineralize the water for taste. The condensate will usually have a lot of mold and dust.
RobGR··on Moist-Electric Wallpaper for Indoor Energy Harvesting and Humidity Management
There are commercially available systems that do that now, one that seems popular in my area is https://www.aquaria.world/ .

As to your question, would it be a problem if everyone did it -- it depends obviously on your definition of "problem", but consider that most people doing this have no way to dispose of the water they take from the air except by putting it back in the air. It might increase regional power consumption, and smooth out nightly shifts in atmospheric humidity, but unless there is a new river running to the sea, the average atmospheric humidity will remain the same.

RobGR··on Sherline Tools Is Going Out of Business
Your experience is unusual for a Bambu. I know of numerous people who have purchased one and you are the only one who didn't have it "just work".
RobGR··on Hister: A private search engine for the pages you visit and the files you keep
I've been using this since the last time it came up on here. I don't have it index every page I visit, I use the browser plugin to tell it to index specific ones. It is useful for sure, but I think it will really shine once I've been using it long enough for it to build up a bigger index of things that are old enough that I've actually forgotten about them.
RobGR··on Ask HN: Would you read a statistics textbook?
I would at least investigate it. I have purchased and read statistics books recently. Mostly the old classics by R.A. Fisher and D.R. Cox and etc, I have a copy of Handbook 91 by Mary Natrella. My questions are pretty simple. I like the "worked examples" approach in Handbook 91.

RobGR··on Rising seas will swallow New Orleans. People need to start relocating now
That's on the other side of the river from New Orleans.

To what I think is your larger point, that project is a small part of the efforts at water control around New Orleans. But, so far they have generally been viewed as beneficial and the various governmental entities keep paying for them -- why should we expect anything different in the future ? Roads get repaved all over the country, bridges rebuilt, and the levees rebuilt. There's always an "infrastructure crisis" of the decade, the chatter is how we as a society judge the expense and confirm it's necessary.

RobGR··on Nitrile and latex gloves may cause overestimation of microplastics
That is a case of a specific chemical in tires, not microplastics generally, or even rubber tire particles generally.
RobGR··on Nitrile and latex gloves may cause overestimation of microplastics
Why do you say "nothing to see here" ? The existence of the earlier paper does not imply that procedures corrected for this afterwards. Is there any published protocol for a study since that first article that mentions avoiding stearate powder from gloves ?
RobGR··on The emergence of print-on-demand Amazon paperback books
I've ordered books that were print-on-demand and had them arrive in 3 days. Some of the Amazon ones will have the exact date in the back, and I can see they were printed the day I ordered it.

For what it's worth, I think print-on-demand is a win overall, while there are lots of low quality stuff out there, the ability of small authors to get published and readers to find rarer stuff out weighs that.

RobGR··on The Official DR DOS Website
I have used a DR-DOS 7 that was set up with a nice task switcher, between terminate-and-stay-resident programs ( not true concurrent processing ).

This setup started WP5.1, a spread sheet -- I think Lotus123, and a graphics editing program. I think it switches using cntrl and the F keys, similar in feel to how a linux machine switches consoles.

I think at the time this was set up, only DR-DOS could do the task switching. I don't know if that is still true.

RobGR··on Rising carbon dioxide levels now detected in human blood
I've thought about making a C02 scrubber for indoor use. The simplest way, using commercial lime, would mean replenishing a consumable to keep it going. The C02 scrubbers that acquarium owners use also don't seem to be able to be regenerated.

I think it would be interesting to see what effect, if any, an indoor C02 level of near 0 would have on humans and mammals. Because your blood has to stay in a narrow PH range, and C02 is part of maintaining that, I wouldn't presume it would be good.

I think a small desktop C02 scrubber might have a market in the same demographic that pays for air ionizers, de-ionizers, HEPA filters and incense burners.
