Fun with Exponential Trends (COVID-19 numbers from Johnson County, KS)

 Just playing with the COVID-19 numbers from Johnson County, KS today.  We've hit quite a spike the last week. From :


So I sampled the last 60, 30 and 7 days data, added an exponential trend line for 30 days and came up with this:

Here - let me expand the end of those trend lines if you can't see them.

60 Days:

30 days:

And 7 days:

Statistics are fun. 

Realistically, we'll end up somewhere in the 60 or 30 day pattern; I don't think the population would support 60,000 active cases of COVID-19 in Johnson County Kansas each week; we'd end up with more cases than people in a very short order.

Aprapo of nothing really.  Off to my next meeting.

Review of "The Killer Collective" by Barry Eisler


The Killer Collective (John Rain, #10; Ben Treven #4; Livia Lone #3)The Killer Collective by Barry Eisler
My rating: 4 of 5 stars

A well-written spy / police thriller, made memorable mostly for the excellent characters. The story is at times secondary to the backgrounds and relationships between the protagonists. The antagonists are one-dimensional and essentially forgettable; you don't hate them you don't like them, they're just there to be an antagonist for the heroes to go after. I enjoyed the book, and am looking forward to reading the newest one out by Mr. Eisler.

Is it worth it to upgrade to DaVinci Resolve Studio?

 For years I've been using DaVinci Resolve free edition to edit and publish videos.  Worked great for me, but now I've found that more and more videos on the web are in 4K, and my capture hardware (Canon 90D, Samsung Galaxy Note 20 Ultra) can capture native 4K. Rendering 4K video, even on a 12 core, 24 thread AMD Ryzen 9 3900 CPU is slow.  20FPS slow. 

Upgrading to DaVinci Resolve Studio lets you use the GPU accelerated codecs to render your video. So, what does that mean?  Instead of using the 12 cores of the CPU to render your video, you get to use the thousands and thousands of video-optimized cores to render your video for publishing.  It also makes a much smaller file size.

In a short test, I found I went from 20FPS renders to 60+ (real-time or better) FPS renders after the upgrade.  And using the NVIDIA h.264 codec gave me smaller file size for the same quality!

As you see in this image - the top render was using the CPU; one minute of video took 2:43 to render. Using the GPU, the same video took just 56 seconds!


And - the NVidia h.264 codec cut the file size by more than half!


Granted, none of this was fancy multi-layered video; just a straight 4K60 video off of the Galaxy of the back yard and the dog.  But overall - it's brilliantly fast and well worth the small one-time expense to upgrade if you are doing any significant video at 4K! 

Oh? The video? Clicken to enbiggen.
