I was just mentioning the Japanese word mojibake on the plain-text thread (https://news.ycombinator.com/item?id=47897681), and here you give an example. In fact, UTF-8 misinterpreted as Windows-1252 is the mojibake I personally encounter most often. Curly quotes (most often a right apostrophe inside a word like can't or it's or didn't) are the most common ones, with em dashes being only slightly less common. The other direction (Windows-1252 text being read as UTF-8) produces � (U+FFFD) everywhere instead, but either way, I still see those from time to time today. But far, FAR less frequently than I used to back in the late 2000's or early 2010's. I used to see — and similar sequences all the time 15-20 years ago, and now it's rare enough that I actually notice when it happens.
Who wants to bet that at some point after the closing of the site, they switched over from a live CMS to a static copy of the site and in the process of doing so things got a little screwed up when exporting data from a MySQL database with the different encoding weirdnesses that can sometimes occur with MySQL and how the db schema was set there.
These kits can have extraordinary longevity. I was playing with Lincoln Logs in 1967. Turns out they got started in 1918. Lego bricks have been around since 1945. The moat created by seriously delighting your customers at a young age is large.
It is a really nice concept. I had never heard of it. But then as GenX at young age I played with Fishertechnik [0] more than with Lego. Around since 1966 [1].
I run workshops about the use of modular systems in facilitating non-expert participation in architecture. One I did (at the CAAD Futures Conference in 2023) was with Zometool. It was a blast and really successful.
In preparation I also got to interview the late great Steve Baer, inventor of the Zome (among many other things - seriously look him up, he's one of the most brilliant people of the past 100 years imo). It was a huge honor.
The book chapter the organizers were supposed to do about the conference workshops never materialized (hrmph), but I've done other little collaborative build projects since, so one day I'll document them all together.

There is some interoperability provision to patents and copyright in European union if I remember correctly but I don't know how broad they are and if they apply to this.
I hope that Lego (not lawyers ofc) would appreciate such creativity approach and hire creators. (E.g. similar to acquihire of OpenClaw creator by OpenAI.)
How many of us do think this way?
I am always jealous (in good way) when I see similar projects.
This thing is from 2012. It's a set of printable models for toy parts that allow interconnecting with a bunch of different construction toys, like Lego and K'nex.
I remember thinking this was pretty subversive and cool back then. My own experience in 3D printing since that time has taught me that there is no way that these parts can ever be printed accurately enough to actually work. It didn't get much traction on the Thingiverse files either.
Super cool, lock-in is very real. We are overflowing with Duplo and Lego sets because I just don't want to deal with another system. There are, of course, other models on Thingiverse, Printables, etc., but knowing these are properly designed to fit and work is a huge plus. Cudos to the team!
Neat idea, but as an adult who builds little machines out of Lego Technic for fun sometimes, the adapter selection seems very limited. In order to make this idea "practical" you would need adapters with a variety of sizes, shapes, and orientations. I guess I'm not the target audience - I can definitely see this being cool for children.
I was so confused recently, when I bought a toy car kit from some German brand which cost 25 euro and came with the pieces all joined together straight from the injection mold, so you had to twist them off one by one, and then the little injection spikes stabbed your fingers while you worked.
Bought an almost equivalent set from Lego (stab-free!) for 9 euro. How does that pricing make sense haha
Economy of scale, Lego can invest the billions(?) in machines and molds that don't leave connection points (?), partially by reusing pieces between sets.
That's an awesome project. I'm sure there are many kids that have been gifted LEGO knockoffs that are not compatible with legos from adults that didn't know any better. A similar "interop" project for those would be great
Almost all (back then, I hear the clone quality is much higher now) were "compatible" but had little to no clutch power, a wall built with some of them would inevitably break at the clone bricks.
I think they would have a very strong case that using the mouse on a product is likely to confuse consumers about the origin of the product and therefore infringe on their trademark.
Is this complaint just for the sake of complaining? You print out the pieces, they connect various toys together. The units could be light-years for all it matters.
There's something about the internet that makes people want to moan in public about nothing.
Whenever I see someone in a current British television show use "inches" or "feet," I'm reminded of the HN metric mafia that insists that the United States is the only place in the world that uses imperial units.
Every post/comment is selecting across 100,000+ people worldwide for the individuals most likely to complain about it.
There’s no other place on earth I can invite 100,000 people to disagree with me. Exception is maybe a public office. (Which the vast majority of people shy away from, for just this reason)
up until very recently, the only units that made it even remotely "universal" was US customary units. Or, as Arduino Vs Everyone on youtube says: "units that have gone to the moon."
Now, i speak larger measurements in metric if i think the person i am talking to understands or doesn't care; but short measurements i still use "quarter inch" or "teenth" or "thou" pronounced like "wow", from the beginning of "thousandth".
I know km, liters - i drink at least 3 liters of liquid a day, if not 4, but i drink it 1 quart beverage receptacle at a time, odd how that fits!
is it really so hard to have a ruler with both measurements? I have a ruler that lets you convert from font point to two other measurement units to inches, for page layout.
I'm american, from the '80s, and we never used metric day-to-day.
the US will be US customary units basically forever. because we're an absolutely massive geography, and there's hundreds of thousands, if not millions of mile markers, speed limit signs, "distance to" signs, speed warning signs, gas stations, etc.
So 2026 is the year where i finally say: Please, please, shut up about this. No one cares.
> is it really so hard to have a ruler with both measurements? I have a ruler that lets you convert from font point to two other measurement units to inches, for page layout.
The problem with the imperial unit system rather is that it does not form something "to build more complicated units out of".
For example: if you want inch (in) as a unit, why not have "in^2" as a corresponding small area unit and "in^3" as corresponding volume unit?
Additionally, there should be constant/regular conversion factors between the various subunits of a measure, i.e.
10^-3 km = 1 m = 10 dm = 100 cm = 1000 mm = 10^6 µm = 10^9 nm = ...
vs
1 lea = 3 mi = 24 fur = 240 ch = 5280 yd = 15840 ft = ...
we don't use leagues or furlongs. I know what a chain is because i have one, but that's specifically to measure land against a plat map. Every location in this country is based off common reference locations (there's a literal marker on the ground), with only chains and angles to delimit things (generally).
Read that last part again, because they use GPS to determine if the marker has moved, and that takes X minutes to quiesce. you can't take X*Y minutes to check each chain mark and angle.. not all land is rectilinear. we have a bit less than ten million km^2 of land in this country.
I'd reckon that maybe 1% of Americans know what a league is, as in the definition. Less for "furlong", less for "chain".
This is how these conversations go, usually. It's completely pointless, most of the people here will never interface with something where this matters. I'm a few decades old - 2.25 score years old, to be accurate. My wife knows what a score is, and how many feet in a mile, which i can never remember; by the by, it's about 5300 feet.
like Celsius, the metric measurements don't "mean" anything directly to a human. a meter is how fast light travels in 1/speedoflightinmeterspersecond. water boils at 100 and freezes at 0. compare to ~100F "roughly median body temperature", "roughly the length of an adult foot", and "roughly the length of the middle bone in your thumb".
yes, for "science" using units that convert is great, one of my favorite things to read is the Frink language unit file for that reason. Metric is cute and ostensibly "well-defined". great, use it.
you're not getting ~400,000,000 people to switch, potentially ever. The sheer cost is astronomical. a speed limit sign, just the sign is ~$22. The total cost of install could be from $500 to $3000. Per speed limit sign. There's at least 10,000 speed limit signs on interstates alone. [nearly] Every single mile of every single highway and interstate in the US has a reflective sign stating what mile it is - except for mile 420, i'm not sure why, that'll be missing but there will be a 419.7 mile marker. weird.
> In 2002, a contractor installed just over 50 miles’ worth of markers on I-78 and Routes 22 and 33 at a cost of $230,000, or about $4,500 per mile. Today, [...] $6,500 per mile, said PennDOT spokesman Ron Young.
and
> As of 2022, [...] the Interstate Highway System, which has a total length of 48,890 miles (78,680 km)
and that's just interstates. We have expressways, freeways, spurs, feeders, highways, state roads that use mile markers. Speed limit signs vary in distance, but figure 2 miles per (raelly 1 per mile since they're on both directions of travel, and usually there's 2 per direction, one on either shoulder) on nearly every commute surface. we have ~2,600,000 miles of paved roads, and a bit over 4,000,000 miles of roads, total, in the US - that's 6.437376e+6 kilometers, or 21 lightseconds in a vacuum, or 32 lightseconds in fiber optic cable. 32000ms ping, awesome.
Every house in the US is built with 16" on-center framing for the walls. we're not going to switch to "406.4mm on center", because our sheetrock, plywood, etc are all 48"x96".
every other country that switched did it 70+ years ago, has less people, or is drastically smaller.
like i said, rudely, but now politely, give it up, we're staying with our US customary units.
> we don't use leagues or furlongs. I know what a chain is because i have one, but that's specifically to measure land against a plat map. Every location in this country is based off common reference locations (there's a literal marker on the ground)
The same holds for more obscure unit prefixes in the SI system like dam (decameter) or hm (hectometer) in the SI unit system (as far as I am aware, the only common usage of the "deca" prefix is in Austria for "decagram" (dag)).
Nevertheless, even these obscure units fit the regular pattern perfectly:
I've been cooking for something like a quarter century, for multiple people, and i have never once, in my life, used a kitchen scale. I have one for doing METRIC measurements of ratios of liquids for other uses, but not once for cooking.
A stick of butter is a quarter pound. it doesn't matter though, because the butter is marked in "recipe increments". if you melt it, you can use "tablespoons" to measure it, literally.
eta: i haven't even used measuring cups or spoons for anything in like a decade, unless i am making bread or bread-like things.
I’m disappointed that VEX IQ didn’t make the list of connections. For a System they have a lot of well thought out parts, they need help on the decoration side and smaller gear patterns.

This is probably the case of a bodged migration from one CMS to another.
My blog suffered the same, and going through loads of old pages to check and fix them just isn't worth the effort.
The archived version from 2012 is showing the characters correct. So probably some migration like you said.
https://web.archive.org/web/20120319180000/https://fffff.at/...
The website itself has been closed since 2015 according to the front page.

Which also suffers from encoding problems making weird characters show up.
But which was showing the characters the way it should on August 1st 2015 when the site was closing down.

I'm not sure that's enough: most kids wouldn't be able to tell a genuine Lego brick from a knock-off.
(Lego famously has insane quality control on their tolerances. But I haven't had any trouble with knock-off bricks so far either.)
I'm sure that Lego still captures virtually all of the revenue in this category, no?
Maybe, I'm not sure. Though Wikipedia demonstrates that you don
Don't forget Erector Sets.
I spend untold hours failing to build a cable tramway between my mother's dresser and bed.

Ditto. My kids are still pretty young, and my old Construx are one of the favorite building toys.

Economy of scale, Lego can invest the billions(?) in machines and molds that don't leave connection points (?), partially by reusing pieces between sets.
With such kits you are generally supposed to remove the parts from the runners with nippers and then sand those nubs down.
That's an awesome project. I'm sure there are many kids that have been gifted LEGO knockoffs that are not compatible with legos from adults that didn't know any better. A similar "interop" project for those would be great
Almost all (back then, I hear the clone quality is much higher now) were "compatible" but had little to no clutch power, a wall built with some of them would inevitably break at the clone bricks.
Crappy tolerance in the clone parts. I hear the clones got much better now.
I feel like the only way to summon the corporate lawyers faster would be to put a Mickey mouse on the box.
Mickey mouse is in the public domain, at last!
I think they would have a very strong case that using the mouse on a product is likely to confuse consumers about the origin of the product and therefore infringe on their trademark.
