    Ok so most monitors sold today support DDC/CI controls for at least brightness, and some support controlling color profiles over the DDC/CI interface.

    If you get some kind of external ambient light sensor and plug it into a USB port, you might be able to configure a script that controls the brightness of the monitor based on ambient light, without buying a new monitor.



  • You say that it is sorted in the order of most significants, so for a date it is more significant if it happend 1024, 2024 or 9024?

    Most significant to least significant digit has a strict mathematical definition, that you don’t seem to be following, and applies to all numbers, not just numerical representations of dates.

    And most importantly, the YYYY-MM-DD format is extensible into hh:mm:as too, within the same schema, out to the level of precision appropriate for the context. I can identify a specific year when the month doesn’t matter, a specific month when the day doesn’t matter, a specific day when the hour doesn’t matter, and on down to minutes, seconds, and decimal portions of seconds to whatever precision I’d like.


  • This isn’t exactly what you asked, but our URI/URL schema is basically a bunch of missed opportunities, and I wish it was better designed.

    Ok so it starts off with the scheme name, which makes sense. http: or ftp: or even tel:

    But then it goes into the domain name system, which suffers from the problem that the root, then top level domain, then domain, then progressively smaller subdomains, go right to left. www.example.com requires the system look up the root domain, to see who manages the .com tld, then who owns example.com, then a lookup of the www subdomain. Then, if there needs to be a port number specified, that goes after the domain name, right next to the implied root domain. Then the rest of the URL, by default, goes left to right in decreasing order of significance. It’s just a weird mismatch, and would make a ton more sense if it were all left to right, including the domain name.

    Then don’t get me started about how the www subdomain itself no longer makes sense. I get that the system was designed long before HTTP and the WWW took over the internet as basically the default, but if we had known that in advance it would’ve made sense to not try to push www in front of all website domains throughout the 90"s and early 2000’s.


  • Your day to day use isn’t everyone else’s. We use times for a lot more than “I wonder what day it is today.” When it comes to recording events, or planning future events, pretty much everyone needs to include the year. Getting things wrong by a single digit is presented exactly in order of significance in YYYY-MM-DD.

    And no matter what, the first digit of a two-digit day or two-digit month is still more significant in a mathematical sense, even if you think that you’re more likely to need the day or the month. The 15th of May is only one digit off of the 5th of May, but that first digit in a DD/MM format is more significant in a mathematical sense and less likely to change on a day to day basis.


  • Functionally speaking, I don’t see this as a significant issue.

    JPEG quality settings can run a pretty wide gamut, and obviously wouldn’t be immediately apparent without viewing the file and analyzing the metadata. But if we’re looking at metadata, JPEG XL reports that stuff, too.

    Of course, the metadata might only report the most recent conversion, but that’s still a problem with all image formats, where conversion between GIF/PNG/JPG, or even edits to JPGs, would likely create lots of artifacts even if the last step happens to be lossless.

    You’re right that we should ensure that the metadata does accurately describe whether an image has ever been encoded in a lossy manner, though. It’s especially important for things like medical scans where every pixel matters, and needs to be trusted as coming from the sensor rather than an artifact of the encoding process, to eliminate some types of error. That’s why I’m hopeful that a full JXL based workflow for those images will preserve the details when necessary, and give fewer opportunities for that type of silent/unknown loss of data to occur.


    • Existing JPEG files (which are the vast, vast majority of images currently on the web and in people’s own libraries/catalogs) can be losslessly compressed even further with zero loss of quality. This alone means that there’s benefits to adoption, if nothing else for archival and serving old stuff.
    • JPEG XL encoding and decoding is much, much faster than pretty much any other format.
    • The format works for both lossy and lossless compression, depending on the use case and need. Photographs can be encoded in a lossy way much more efficiently than JPEG and things like screenshots can be losslessly encoded more efficiently than PNG.
    • The format anticipates being useful for both screen and prints. Webp, HEIF, and AVIF are all optimized for screen resolutions, and fail at truly high resolution uses appropriate for prints. The JPEG XL format isn’t ready to replace camera RAW files, but there’s room in the spec to accommodate that use case, too.

    It’s great and should be adopted everywhere, to replace every raster format from JPEG photographs to animated GIFs (or the more modern live photos format with full color depth in moving pictures) to PNGs to scanned TIFFs with zero compression/loss.






  • In addition to the stone/clay based works that you might be thinking of, I find certain metalworking sculptures to be interesting, too. Alexander Calder made a bunch of red steel sculptures, almost architectural art, in addition to things like dynamic mobiles. Louise Bourgeois’s “Maman” is an interesting one, too.

    There are small metal sculptures, too. From little trinkets made from wire, to welded metal parts, to elaborate chandeliers, these all involve artistic creativity in manipulating materials in a three dimensional space, and it’s a skillset that I admire and respect (and do not have any, myself).


  • Weight distribution and jiggle control is something I can’t relate to though

    It’s not hard. Put on a really heavy backpack and leave the straps super loose, and go try to move around, maybe a few athletic moves that involve changing speed or direction. Compare to a tight backpack with a waistband and shoulder straps properly strapped to your body, and try to move around again. The straps help control the extra motion so that you’re in better control.

    Or run around in shoes 5 sizes too big. Or go for a run with your arms loose and intentionally left limp, swinging around like pendulums.

    The whole world has a million examples of why providing bracing and support makes for more efficient and comfortable movement.




  • Or is a by product of its former format, the live laughs with a crowd while filming?

    This is the reason. Television comedy derives from stage shows where the audience sits in one direction from the stage.

    A lot of early television comedy programming was often from variety shows, where the live studio audience is an important feedback mechanism for the actual performers. A standup comic needs a laughing audience to respond to (and often, so do other stage performers, including sketch comedy).

    So television comedy comes from that tradition, and a live audience was always included for certain types of programs. Even today, we expect variety shows to have audiences. For example, John Oliver’s show without an audience felt kinda weird while that was going on in 2020. And even some pre-filmed sketch comedy shows, like Chappelle’s Show, would record audiences watching the pre-recorded sketches as part of the audio track for the broadcast itself, while Chappelle himself was filmed essentially MCing for that audience and those sketches.

    So sitcoms came up on sets with live performances before studio audiences, just like sketch comedies and variety shows or daytime talk shows. That multi camera sitcom format became its own aesthetic, with three-walled sets that were always filmed from one direction, with a live audience laughing and reacting. Even when they started using closed sets for safety and control (see the Fran Drescher stuff linked elsewhere in this thread), they preserved the look and feel of those types of shows.

    Single camera sitcoms are much more popular now, after the 2000’s showed that they could be hilarious, but they are significantly more expensive and complicated to shoot, as blocking and choreography and set design require a lot more conscious choices when the cameras can be anywhere in the room, pointed in any direction. So multi camera still exists.


  • On the other extreme, 24/7 operations have redundancy.

    A friend of mine explained that being an Emergency Medicine physician is a great job for work life balance, despite the fact that he often has to work ridiculous shifts, because he never has to take any work home with him. An Emergency Room is a 24/7 operation, so whenever he’s at home, some other doctor is responsible for whatever happens. So he gets to relax and never think about work when he’s not at work and not on call.
