> We bought a $1 house in Italy. Here’s what happened next (CNN Travel article)

> the last link is also a lie

I was wondering if “lie” was too strong a word, but no, CNN is straight up lying in article’s title. Deep into the article they admit it:

“I’ll be honest, we didn’t buy a €1 house,” he says. “We were shown something like 25 old buildings, some badly in need of repair, so at the end we opted for a three-room decent building for €10,000 and I invested more money in the renovation.”


The business model of the S1 is just wild. It mimics the PC clone industry of the 1990s.

From the Wikipedia page:

This product is what is referred to as a 'common mold' which means many different suppliers can produce this same model. The manufacturers are almost exclusively located in China.

Primarily defined by the use of a system-on-a-chip of one of the Actions brands and some common core features, S1 products vary widely in software and hardware as well as design.

I counted 62 different manufacturers listed in the Wikipedia article that apparently licensed this reference design (the core features and basic hardware), and who then made variations to the user interface or added a feature or two, and slapped their names onto it.

There seems to have been a whole industry of MP3 Players that were essentially identical at the core electronics level in the early 2000s, and we never realized it.


DankPods on youtube has a long running series documenting these low cost mp3 players, or as he calls them, nuggets.


i remember it very well, i bought a Sony at F.Y.E. at the mall. as a child, my mother insisted on Sony as it was reputable brand (thank god because they truly were better devices). But the non-Zune/Sony/iPod selections were all duplicates of the same garbage, this was ~2007.


It could be snaps[1]. Google for "denim jacket with snaps" to see examples that match the fasteners in the image. I too can't decide if it's a real photo or AI generated.

I was going to ask what this meant about strawberries:

> LLMs make mistakes that basically no human will make, like, you know, it will insist that 9.11 is greater than 9.9, or that there are two bars of strawberry. These are some famous examples.

But you answered it: It’s a stupid mistake a human makes when trying to mock the stupid mistakes that LLMs make!


The HP 185A oscilloscope[1], 500 MHz bandwidth, was $2000 in their 1960 catalog[2]. That would be $22,000 in today's dollars. (The brochure doesn't say MHz but uses MC meaning megacycles.) It would be fun to compare the specs to a cheap hobbyist level scope today.

I’m sure someone has done this, but it would be interesting to study the overall tech landscape and compare which technology has sort of retained its value, depreciated, or increased in value—and how long those phases take. Even as far back as things like cast-iron printing presses and such. I mean also value in terms of usage not necessarily monetary.

The cycles we go through where a new tech supplants an old one, people thinking it’s the way of the future, and the old processes maybe forgotten for a while. Some might come back, others completely obsolescent. Still others the old tech might be superior to new—but more expensive (like old hard-wood window panes) and not sustainable.


I remember finding HeNe laser interferometers in an old HP catalogue from the '70s and being surprised that buying the equivalent system today from KeySight actually costs much more, even adjusted for inflation.


Interesting—I guess build quality and certain technologies that don’t change much makes supply-and-demand takes over.


Historically, technology has been deflationary.


I think I have this scope or a very similar one. I got it for free from someone else. (currently in storage.) It's a great hobbyist scope although mine doesn't have a DFT function which can be annoying. I've been borrowing a friend's modern digital scope when I've needed one. I think he only paid a few hundred for it. It's a little faster and has some more modern functions.

EDIT: Oops nope. Looked at the model number rather than the brochure. That's definitely an older analog scope while mine is digital.


Given the great distances and how small the planets seem at that scale, I'm surprised that we can see any of the planets with the naked eye. Thinking about Jupiter, it's 140K km in diameter and about 629M km from Earth. That's a ratio of 1:4500. So imagine a U.S. dime that is 1.8cm in diameter placed 1.8 x 4500 = 8100 cm away. Would you be able to see a dime that it 81m or 266ft away at nighttime, assuming it slightly illuminated? We can see Jupiter, so I guess we should be able to see the illuminated dime too.


> You have to power up your SSDs every now and then for them to keep data.

What is the protocol you should use with SSDs that you’re storing? Should you:

- power up the SSD for an instant (or for some minutes?) without needing to read anything?

- or power up the cells where your data resides by reading the files you had created on the SSD?

- or rewrite the cells by reading your files, deleting them, and writing them back to the SSD?


I'd at least just read all the used blocks on the drive. partclone is the most efficient that comes to mind, because it just copies used sectors. Just redirect to /dev/null.

    partclone.filesystem --source /dev/sdx --clone --output /dev/null


If you just need to read all of the sectors, then couldn't you just dd or cat the source drive instead?


>What is the protocol you should use with SSDs that you’re storing?

The correct protocol is to copy the data to a more durable medium and store that.


Or leave the drive on all the time in an enclosure that keeps the nand cool (near room temperature).

Any decent SSD will background rewrite itself over time at an appropriate rate. Detecting that it needs to do so after 2 years in storage seems trickier to get right (no realtime clock) and trickier to test.

I’d be curious to know how quickly the drives in the article “heal” themselves if left plugged in. There’s nothing wrong with the hardware, even if they did lose a few sectors.

If you really want to create a correct protocol, you can accelerate nand aging by sticking them in an oven at an appropriate temperature. (Aging speedup vs temperature curves are available for most nand devices.)


Maybe someone should design and sell a "drivekeeper" that you can plug all your backup SSD's into and it will power them up on a time table and do whatever is necessary to cause them to maintain integrity. Could be something like a Raspberry Pi with a many-port USB hub, or with a PCB with a bunch of connectors the raw drives can plug into. Could maybe even give a warning if a drive is degrading. Possibly it could be a small device with a simple MCU and a battery that you snap directly onto the SSD's connector?


Do all trades get reported to some agency of the government (including those done in private rooms)?

Do companies themselves know who owns their shares (including those done in private rooms)?

If the answer is no to either or both of the above, doesn't that create all sorts of ownership problems? As an analogy, I'm imagining a country where there is no reliable municipal property registry, and no one knows who owns a particular house. Wouldn't that create chaos?


Yes there is a record for most trades done. The regulating body depends on the type of instrument (equities, options, futures, fixed income, etc.)

The Consolidated Audit Trail (CAT) is the primary location for this data as it relates to equities. https://www.finra.org/rules-guidance/key-topics/consolidated...

The settlement cycle also dictates the frequency of reporting for many investment instruments. https://www.finra.org/investors/insights/understanding-settl...


>As an analogy, I'm imagining a country where there is no reliable municipal property registry, and no one knows who owns a particular house. Wouldn't that create chaos?

That's basically how it works in many (most?) US states. There's no authoritative record of all claims on a property. Land registries exist, but they're not authoritative. Liens can exist without being registered on it, and surface later. Hence the need for "title insurance".

> one of the best texts on Galois Theory I have read

What book on group theory or abstract algebra would you recommend to read first to be able to read that text on Galois Theory?


If I'm being honest I really don't have a good recommendation for a text in intro abstract algebra. I learned it from Michael Artin's Algebra. Artin is a true master -- along with David Mumford, he was the main apostle for Grothendieck style AG in the US -- but his book was not very easy to learn from.


Just wanted to point out something that not everyone might realize:

Unicode is not supposed to have fonts at all. Unicode defines characters that you can then represent in various fonts. It just so happens that Unicode has many characters that happen to look like the letter "C" (as an example): © for copyright, ℂ for complex numbers (formally called Double-Struck Capital C), etc. The author uses these many variations as a fun way to make "fonts".


If you want to dive into the details, you can copy the "fonted" output to a unicode analyzer. [0] is an online unicode analyzer that seems to work well.

[0]: https://devina.io/unicode-analyser


I often reach for jq to understand what unicode is in a string, e.g.:

  [wl-paste|xclip-o|pbpaste] | jq -R --ascii-output
It doesn't provide any per-character explanation, but it is local and I already have jq installed.


But Unicode is such a historically grown monster that it violates its own rules in many places.


Is it? Even emoji---one of the most controversial additions ever---was fully justified for its possible accessibility issue when it was introduced in Unicode.
