I mistakenly thought that YouTube hit a compatibility problem with my Firefox browser. The only breakage I could see was that the right sidebar of related/recommended videos disappeared. But I was watching several videos consecutively just fine. (I obtained video links from recent bookmarks, plus manually queued URLs of next videos to watch.)
Toronto Parking Authority is guilty of this. If you pay at a terminal on the street, then you're charged the exact amount needed for your parking session. If you pay using the mobile app, then it charges your credit card in increments of $20, requires your mobile phone number as an account identifier, and keeps track of your remaining monetary balance.
If you have an ISO-invariant camera, then yes - the final image would look the same whether you shot at low ISO and raised it in post versus shooting at a high ISO and doing no further editing. You can try it yourself. Or you can read the numerous reviewers who have already done that in the past decade, such as DPReview.
Excellent presentation and explanation. I agree with ~90% of it except the small part at 4m54s where he tries to give an answer about the existence of noise. Yes, sensor readout noise and A/D quantization noise exist, but he forgot the big elephant in the room: photon shot noise ( https://en.wikipedia.org/wiki/Shot_noise ). Light is inherently quantum mechanical, and the lower the brightness of a scene, the more that the discrete nature of light shows up in captured images.
Lately I've been researching cameras for astronomy, especially for deep-sky objects (DSOs) like nebulae that require hours of exposure time. The marketing material for these cameras go into a lot of detail: quantum efficiency (the percent chance that a photon converts into an electron), dark noise at different temperatures (fractions of electrons per second), readout noise (usually around 1 electron), and well depth (usually around 10k electrons). Compared to general photography, the astro community much more motivated to explain and keep track of all the sources of noise.

Agreed. In other words, ISO is not exposure. Exposure is purely about how much light arrives on the sensor - which is a combination of scene illumination, object reflectivity, relative aperture, and shutter speed. ISO only plays a part in controlling how bright the output image is.
I like the lack of unsigned integers in Java. It simplifies the language while only removing a tiny bit of functionality. You can emulate almost all unsigned math using signed operations, whether you use a wider bit width or even the same bit width. The only really tricky operations are unsigned division and unsigned parseInt()/toString(), which Java 8 added to smooth things over.
The reason for using unsigned is not that some operations need it, it is so to declare a variable that can't be negative. If you don't have that, then you must check for a negative number in every single interface.
> Some people who never play the piano claim it would be easier if had all white keys, or simply white alternating with black.
Actually, I'm one of those people. For over 20 years, I struggled with playing piano because I would have to memorize a different fingering pattern for the major scale in 12 different keys. I knew the mechanical process of it, but it was hard to develop the muscle memory and play songs by ear based on intuition alone. So I was most comfortable playing in C major (white keys only) and using mechanical/electronic transposition.
In the year 2024, I stumbled upon the Janko piano layout ( https://en.wikipedia.org/wiki/Jank%C3%B3_keyboard ), which turns out to be the smallest modification to standard piano that results in an isomorphic keyboard. I kid you not, I was up and running in less than 5 minutes - I just treated the layout as if it was a pattern to learn on standard piano, except that it was the only pattern I ever had to learn. On Janko, I found it much easier to play songs by ear, in any key. I wish I discovered Janko earlier, as standard piano was never a good fit for my brain.
For anyone who is curious to try, here's a software Janko piano keyboard that you can play right in the web browser: https://novayashkola.org/janko/
I suppose that's why the harpejji [0] has recently gained popularity? I too have wished for an isomorphic keyboard. All of the non-stacked ones become either too wide or the keys become too skinny. Example: Dodeka Keyboard [1]. I know that the Lumatone [2] exists too, but it is too progressive for my taste :)
As a side note, the traditional keyboard size is not representative of the average pianist's hand size. David Steinbuhler [3] has been making modified traditional keyboard layouts
by varying the width of the keys slightly, and people rave about it. I've had the chance to visit his shop in Titusville, Pennsylvania, where he designs them. It's a totally enhanced playing experience, even for someone like me who can play a 10th without difficulty.
