xxs··on Reasons robotics is hard
Small cleaning robots have existed for long enough. For floor sweeping they are more efficient than any 2-legged form.

Not folding the laundry, though.

xxs··on Dutch central bank moves share of gold from U.S., Canada to London
likely at some point the gold bars would be ferried as well if the 1s and 0s fail to balance anytime soon(ish)
xxs··on Dutch central bank moves share of gold from U.S., Canada to London
gold has quite the inherent value - no oxygen reaction (all electronics) and partly jewelry.

if the gold has cheaper would be used quite alot due to being the only metal not oxidizing (the other one being platinum which is even rarer and comes from the same ore source)

> “not looking like it was made with injection molding”

Aside machining POM, what else is there. Injection molding tend to be great.

xxs··on Hacking IKEA Furniture
Solid wood is cool in a way of being cool. It's dimensionally unstable to a point is not permitted for cabinetry in some countries. Also it's expensive and it takes a lot of time for a tree to grow to be turned into furniture.

In that regard plywood (or glulam) is still wood that can be laminated and stained/oiled, if one insist on wood.

>would be very expensive

very doesn't even begin to make it justice.

You are not supposed to do that, and if you do - use PVA and epoxy, +metal insert and machine bolts to reassemble

xxs··on It takes 5 cloud services to hear my doorbell
The activation, door knob can be trivially implemented with just piezo-crystal pulse and some radio (433MHz). No battery required, either.
xxs··on It takes 5 cloud services to hear my doorbell
I have got a cheap candy-land made doorbell that's operated via piezo crystal switch (non-battery, non-power-line) and 433MHz freq. It has some melodies and volume built-in,

The design is simple and easy to hack (and build something else). There are rather cheap light switches that operate on the same principle and can be used.

It took around 15kJ to access the site... that's a proper waste and somewhat sad, even though I understand.
xxs··on U.S. State Department pauses immigrant visa applications
in the EU there is no need for any visa (within member states) and essentially it's a desired feature of the EU.

Another point is that speaking the local language in a richer country of the EU is less likely than speaking English (with English being official only in Ireland and Malta), so it's harder to settle - esp. with kids and school.

xxs··on Value Classes Still Need Compiler Sympathy
The object header overhead was always present and expensive in massive arrays - the classic example would be the Point class that has two "double x, y". Realistically the value classes make sense most (only) if they are placed in arrays. In order to use tons of points you'd end up having two arrays, double[] x, double[] y... or go even with direct buffers.

Personally, I don't care about the tiny optimizations possible in cases of just using few of them, e.g. Integer, as int[] is an option, and even writing custom maps where the keys are placed the said array ain't difficult.

As for performance, often times I had to PrintAssembly (the article mentions that at the bottom) to ensure the compiler did its bests, e.g. optimizing away boundary checks, inlining calls, etc.

xxs··on Tooltips need a delay, and then they need to skip it
a rather poor idea - esp. the frame part, mouse movement is not related to the display frame (rate). The latter can be rather high, e.g. 240Hz which is 8ms. Having a set delay and be in the boundaries (and not leaving it) is a significantly easier solution and easier to test too.

Overall the delay in tooltips (and configurable) has been a feature since the 90s (could set the delay in millis in some UI frameworks)

xxs··on Why some US restaurants are banning tips
I have not been in a place in Europe where the tips would be rejected. However, universally they are not the norm or expected.

Also about the $10 - they would need to gather quite a few more dollar notes and spend time finding a cash exchange bureau. Else the note is just a memento of a weird American.

In some EU countries the tips have to be counted as salary and income (+social) tax paid, or even they have to be declared as revenue to the restaurant along with the VAT (19-25%) going straight to the state. Of course, when paid in cash - that rarely happens. The point is that the provision exists in the law (so the tips are not unheard of)

xxs··on Why some US restaurants are banning tips
A massive price difference would be the drinks (also the most of the profit) - realistically opening a bottle of expensive wine vs the bog standard cabernet serves as no proxy to anything.

Likely certain single malts vs jim beam.

xxs··on New EU-wide product repair rules come into force
I don't know of any PC motherboard to be 20-layers. "Asus ROG Crosshair X870E Dark Hero" is like 650 euro and it's "merely" 8 layers. Edit: "MSI MEG X870E Godlike" is 1200 euro or so and 10 layers.
xxs··on New EU-wide product repair rules come into force
TV, unfortunately, are the worst offenders in most cases as they cannot be reliably opened.

Things that are on the not hard scale to fix - cleaning robots, inkjet printers (with fill-in ink), laptops (incl. board repairs as long as they are not a BGA), desktop pc, mowing robots, mowers (all 2 and 4 stroke variants), most battery tools (drills, sanders, saws, etc.). Overall stuff that can opened reliably, even if that requires specialized tools like bearing pullers or impact wrenches.

Things that are hard - anything that uses glue as the prime assembly fastening choice, e.g. TVs and monitors (or just plastic clips). Cheap plastics (ABS) bodies are annoying as well. Fridges, no way to refill or fix the compressor. Serialized components that need specialized tools/software after being replaced.

In that regard that would be my complaint - ease of disassembly and clearly marked parts, exploded views, schematics. Spare parts. Personally, I'd spend half a night to repair 30-40euro device w/o any documentation, just b/c I can -- but that shall not be the norm.

xxs··on New EU-wide product repair rules come into force
>demanding that they support hardware indefinitely is unreasonable.

nobody demands that - it's more of the fact the hardware is locked and serialized, e.g. it won't accept a blue tooth module unless it's unlocked with proprietary software.

The hardware manufacturers spend quite the effort, so the devices are not open and require designated tools for minor fixes. I can imagine it not wanting to perform a warranty repair but that's the end of it.

xxs··on New EU-wide product repair rules come into force
The intellectual property is not some god given right unlike air and water. There is little need not to support a decade old hardware and effectively turning the said hardware to a door stop, or a landfill.

Btw, it's difficult to believe the post is a good faith argument.

the main issue is that's an ipad and it's locked. In contrast - a 15y+ laptop can be used (after few upgrades - i5-560M, 8GB RAM, 500GB SSD, AC-8260) to do office work: it runs the latest Firefox and Open Office + googledocs and friends without too much trouble.
xxs··on Canada will match US tariffs 'dollar for dollar' as trade talks break down
Geography as in softwood forests, instead of the iconic maple leaf. In no way Canada would be importing 30%+ of its construction timber from the US. Canada is a major softwood timber exporter.

xxs··on Claude writing a macOS driver for my obscure HP printer built only for Windows
requiring a full blown VM (with a different OS) to implement a driver (normally that would work in ring-0 along with the original OS) is not pedantry.

for instance the 'windows' part is also entirely nonsensical as the printer works on a default mint installation w/o any issues. The "obscure" part is weird as you can just buy the printer online as well.

xxs··on Meta's blockbuster trial draws parallels to big tobacco
The examples don't hold in most jurisdictions (except for the stock market and if short sells are allowed).

All of the three categories are defined as gambling in pretty much all jurisdictions across the globe. However, they are classified as different types, e.g. roulette is closer to slots than poker is. Then poker can be "cash tables" vs "tournament". The main classifier difference is "game of chance" vs "game of skill", yet there are lots of nuances.

xxs··on Asynchronous I/O in DuckDB: Work, Thread, Work
I can't say it's 'deep' in any way, e.g. what type of queue is that? Another part - utmost importance to keep async threads fully busy - that doesn't address what kind of disk subsystem is and how it deals with random reads.
