My LG OLED TV does have a headphone jack, and I send that through a mixer (combined with my CRT gaming setup's output, my record player, and my PC's output) to my stereo.

It's the ergonomics that I have an issue with.

I always viewed the classic scroll method as a mirror to what happens on screen.

Speaking of "natural scrolling" it is horrible because most scrolling is downward and "natural" is an ergonomically inferior pushing action instead of pulling.

It's only natural on the actual display itself.

Anothe affront to nature by Apple, along with killing the headphone jack.

The thermistor looks like a Semitec ###NT series, if you want the exact one.

103NT H34G, I suppose?

I figured 300 megabit Fios would be enough but I think that when you cheap out, they more severely throttle places like Youtube on the backend.

The PH-0 and smaller screwdrivers from Good suppliers like iFixit or Wera are actually JIS because there's no downside.

But if you happen upon a real PH-0 it will destroy the JIS screws.

Third party lenses that cannot be updated by the camera body will include a USB port.

The author says PH screwdrivers may be used on JIS screws, but in my experience they strip every single time.

This is incredible work, though.

I did it with no reference to other fonts, just to my own tastes. It took a bit of iteration to get letter centering on the lower cases to work well but I think it's in a good place.

You can see an older version ("a" has been revised to better center the letter) in action on a monochrome CRT here: https://github.com/PhobGCC/PhobGCC-doc/blob/main/For_Users/P...

I made myself a pixel font for composite (well, monochrome) video output on an RP2040:

https://github.com/PhobGCC/PhobGCC-SW/blob/main/PhobGCC/rp20...

(search for 1 to see letterforms)

The letters are 8x15 and verticals are 2 pixels wide to work better on older CRT televisions with less-sophisticated chroma filtering on their composite inputs.

I explicitly tried to avoid locking into 45 degree diagonals...

My only question now is, how do I turn this font into something I can use on a computer? I couldn't figure it out the last time I tried.

I guess I wasn't being precise, I meant Nelder-Mead.

If you can put something in it it doesn't count as crumple zone and the car has to be engineered with a separate crumple zone anyway.

What has changed is that the US's failure in Iran has directly impacted many of its former allies all at once, and the current administration clearly shows that it doesn't care about them at all.

This lack of consideration will lead to significantly less favorable trading for all of the businesses you listed, regardless of their current prowess.

If you buy a ChaDeMo Leaf you do so knowing that it will likely never go more than a hundred miles from home.
