The millennials are moving in.  Despite all the rumors, it would be surprising if millennials were making equal or less than generation X by the same age.  



The lion kingdom has slowly devised a solution to the synchronization errors which accumulate when editing video with audio.  It doesn't involve bonding audio & video tracks the way other editors do.  It's believed the mane source of timing errors is video being aligned to frames & audio being aligned to samples.  Samples & frames never line up at the same point in time, so every edit has a 1 sample misalignment.



The idea is to make all media types use 64 bit nanoseconds as their time units.  64 bit nanoseconds would have a rage of 100,000 days & be easier to work with than float.  The highest sample rate of 192khz would have 5208 positions in each sample.  The highest normal frame rate of 60fps would have 16,666,666 positions in each frame.


If it was double precision float, the range would be 52 days before precision deteriorated below nanoseconds.  The variable precision based on absolute value has made floating point difficult for timing.  Rounding tends to go 1 way in a short sequence but the other way in a long sequence.


The key is all edit decisions would be in fractions of a sample & fractions of a frame.  They would be rounded during playback.  This would introduce some new problems but would overall end the synchronization errors.  The mane problem is ending up with fractions of a frame.  Some prioritization of the slowest media type over the fastest media type is always going to be necessary.


The user would have to use alignment of edits on frames to make sure all edits were on frame boundaries.  It would be accepted that audio ended on fractions of samples when there was video.  Playback would have to round the fractional sample or frame to avoid cases of 1/5208 of a sample causing the entire sample to be played or 1/20,000,000 of a frame causing the entire frame to be played.  None of the edits would end exactly on a nanosecond.  It would be entirely dependent on rounding.


It would be a big rewrite, but theoretically involve manely cut & paste.  Interestingly, the conversions  between samples & seconds were written in 1997 & were the 1st bits to be written.

Lions long viewed the neighborhoods bordering the office park as the primest locations.  New construction is always the cheapest time in a house's lifetime.  The houses being

 Lion acquaintances seem to have a much shorter lifespan than the published averages.  55-65 seems to be the norm.  Maybe life expectancy is a camel like inflation.  Die by 60 or make it through the great filter & hit 100.   ---------------------------------------------------- Ongoing struggles with Xfinity/Comca$t convinced lions they're now better off renting the XFI gateway than attempting to use a 3rd party modem.  It wasn't this way in 2016 when activating a 3rd party modem was straightforward.  That modem lasted until 2022 but seemed to not survive the migration to a monopoly.  In 2016, AT&T was a viable alternative.  By 2022, Commie was the only option. 3rd party modems are no longer supported via online activation.  It's not clear why the app provides an option to activate a 3rd party modem that merely redirects to the xfi gateway activation & fails when it tries to configure the gateway.  The modem goes into walled garden mode where you get DHCP, DNS, b

 Finally watched Creepshow, 40 years after rereading the comic book many times by flashlight. The highlight visually might have been the now vintage Apple II which was cutting edge in those days. Nothing utterly terrifying.  Better writing than anything current.  Only slightly deviates from the comic book. The highlight emotionally might have been when after feeding his wife to the warewolf, the now liberated man sits down to doing anything he wants.  The big deviation was the warewolf escaping in the end, while the comic book kept him trapped underwater. The zombies might have been easier on the eyes than the single women. The original comic book is now on archive.org with a 1 hour free trial.  With a 4k monitor, all you need to do is screencap it while turning the pages.  The raw images are very high res but a 4k screencap is still higher than any animal would actually read it in. Helas, the center page crease is cropped off. There's enough in a 2850x1890 screen cap to remember w
