For workplace protection helmets there are two European norms: EN 12492 for climbers and mountaineers requires >50kg holding force on the chin strap, to not come loose in case of a fall. EN 397 for industrial hard hats (on the ground) require chin straps to open on <25kg, to protect the wearer from strangulation in case of a fall.

You may want to look at it from a non male perspective: for smaller people and tighter trousers or small exterior pockets on skirts and other clothing the smaller (mini) version often just fits and is one comfortable to wear even with regular movement (think of very tight stretching jeans).

I think it's important to note that streaming services mostly take a fixed fee. This dispute was between the artist and the label. The difference in royalties was part of the record deal and Four Tet reached a settlement with this former record label.

Video walls are suitable and are used. There are no seams between the panels and realtime rendering is fast enough for moving cameras. All camera movements are tracked, a virtual camera at the exact same position renders the image which is then shown on the LED wall. The image outside of the panels will be masked with a seamless transition (biggest obstacle here is video wall brightness vs. studio lights). Delays are adjusted for.

You can see how this works in a very small set here: https://www.youtube.com/watch?v=mhmYawxWfjE

And here you can see how the image moves when the camera moves: https://www.youtube.com/watch?v=6koVH1vmLp4

The combination of the technologies is product of the last 2-3 years, but it is already used around the world and a major benefit is that there is no additional post production needed.

Beside the size it's probably a tradeoff on mechanical integrity: a keyring can introduce immense mechanical stress. On my last tag the small loophole just broke away after a year on a key that was not used daily or in harsh environments. With the AirTag you can just replace a $2 third party accessory. Apple didn't have to engineer a very durable (maybe milled?) loophole, which would have increased cost.

Interesting side note: The designer of the map Pasha Omelekhin seems to work mostly for the Russian agency Art. Lebedev where he was also involved in the official redesign of the new Moscow metro map [1]. They also have detailed process descriptions for most of their projects.

Among others the agency works for big Russian state owned corporations, like Gazprom.

Why three prongs? 14 years ago

Current installations use Residual-Current Devices instead of individual breakers, at least in Europe. This requires three way wiring up to the distribution. In Germany RCDs are required for all outlets in new installations.

Can absolutely confirm that. For me it looks like something that is designed by Microsoft (mainly because of the fonts).

There are too wide spaces between text and metadata, too lwo contrasts between light shades of grey and a disrupted context for some elements (see My Profile and Search).

a) With your background you should not have any problems to learn PHP. If you start, don't begin with a big complex system, like a blog or a forum. Try small scripts and learn about web secruity and PHP pitfalls. Then you are ready to begin something bigger.

b) If have experiences with Java, try one of the PHP Plugins for Eclipse.

c) CodeIgniter is mostly based on PHP 4. This results in same outdated patterns, especially regarding PHP 5.3. If you want real extensibility (and highly object orientated code) try the Zend Framework. If this is a bit too much, i recommend the Yii Framework, it's lightweight and brings lots of ideas from rails to PHP without copying the rails specific approach.
