Works for me, Firefox 152.0.4 on macOS 27 beta3.

I don't agree with "the west forgot how to make things", it moved supply chains for cheap consumer goods to asia, but in the B2B space a lot of things are manufactured in Europe: companies like Bosch, Volkswagen, ASML, Alstom and Airbus are cranking out extremely complicated machines that last many years in demanding environments. It's just a different level of value-add vs. low cost electronics (for instance).

Well, these numbers are averages between people living until old age (65+ years) and high infant mortality. I don't think most people keeled over when they reach 25 years...

Office for Mac 2008, when they shifted to a new codebase, was pretty good for a while, just slooooow.

Airline-like comfort, and airplane-like noise. It's surprising how much noisier the Shanghai Maglev gets once you approach 400kph.

Large parts of the OS are open source though. Not just the Linux kernel and userland, but also some specific things:

Mediatek is a taiwanese company and the Dimensity 7100 platform includes the cellular stack.

This explains a lot, American microwaves have these settings for different types of food etc, it seems most people throw something in and just 'nuke it'. European microwave ovens on the other hand, have a setting for different wattages (90W up to 720W 'Max' in my case), which, combined with instructions in the recipe or on the box, provide the right setting for this particular food.

Sure, however as explained further in this thread the BFI approach is new as opposed to the courser Zigbee RSSI-based approaches of Hue MotionAware.

Thank you for adding this context of this particular research, I do see that it relies on MU-MIMO information, which does rely on more powerful WiFi infrastructure than the basic ESP32's I am referring to.

Yes, you won't be able to do this on normal wifi traffic typically either, you need to send specific packets at a high enough rate (in between normal internet traffic) in order to sense with any accuracy, as I also remarked earlier: https://news.ycombinator.com/item?id=46976849

I was shocked to find that even electronics that are collected in Europe seem to be shipped to Africa, set on fire, and at most, metals are collected from the ashes, including traces of gold and copper. That's about it. Batteries have a bit better recycling path but not by much.

Verizon has a security feature built around this, https://www.xfinity.com/hub/smart-home/wifi-motion

Philips WiZ bulbs: https://www.wizconnected.com/en-us/explore-wiz/spacesense

Alarm.com also supports such sensors: https://poweredbyalarm.com/eventresources/wp-content/uploads...

What happens is that a large body of water (pun intended) has the ability to absorb and reflect wifi signals as it moves through the room. For this you need to generate traffic and measure for instance RSSI or CSI (basically, signal strength) of the packets. If you increase frequency you can detect smaller movements such as arms moving vs. a body, or exclude pets if you reduce sensitivity. It works well for detecting presence and movement in a defined space, but ideally requires you to cross the path between two mains-powered devices, such as light bulbs or wifi mesh points. Passing a cafe doesn't seem too likely.

If you want to do advanced sensing, trying to identify a person, I would postulate you need to saturate a space with high frequency wifi traffic, ideally placed mesh points, and let the algo train on identifying people first by a certain signature (combination of size/weight, movement/gait, breath / chest movements).

Source: I worked on such technologies while at Signify (variants of this power Philips/Wiz "SpaceSense" feature).

With the age of retirement (in europe) steadily increasing, and the workforce getting older, the typical corporate position of rejecting older candidates will need to change, if only simply to fill the vacancies. For this, the mentality of hiring managers and HR will need to change as well, and business school articles like this should help.

Local news sources[1] show that the unions and works council are outraged. That's only a start.

What’s more surprising is the fact that the seem comfortable letting go of 1700 people with knowledge of the company and processes.

Dutch government stepped in last year to help facilitate a anticipated growth by fast tracking infrastructure and housing investments, as ASML is building a new campus for 20.000 employees. Then do they expect the 1700 to wait and come back in 2-3 years when the new campus is planned to be operational?

One of the most startling differences between Chinese and European cities is the lack of grafitti in China. I wonder if it's explained by laws, norms, enforcement?

The TiO2 will likely rub off and need regular replenishment. Also, the alternative here, sensor-operated or button-operated automatic doors are already widely used. I wonder who this is meant for?

When I was young and having access to internet (but pre social media) I loved looking into these theories, prompted by Discovery Channel's "Quest for the lost civilization" and stumbling upon these books from the 1970s. It felt like doing research and archaeology on the nascent internet.

I was surprised to see these ideas becoming so mainstream with Ancient Aliens, and then somehow finding overlap with the alt-right, antivax and Covid-doubters. This made me really turn off of taking this seriously.
