Do you have a 4K TV? Are you contemplating an 8K TV? Maybe…take a breath.
I say this as a guy who has a 40 inch HD set (that’s 1920×1080 pixels) in a smallish room, and given the distances, the available content, and our aging eyes…that’s plenty good enough.
An article in TechHive sums it up in a headline: 8K vs 4K TVs: Double-blind study by Warner Bros. et al reveals most consumers can’t tell the difference.
In collaboration with Pixar, Amazon Prime Video, LG, and the American Society of Cinematographers (ASC), Warner Bros. recently addressed this question in a well-designed, double-blind study to see if people could discern a difference between 4K and 8K with a variety of content.
For the purposes of this article, “4K” refers to a resolution of 3840 x 2160, and “8K” refers to a resolution of 7680 x 4320. As you might already know, these definitions are something of a misnomer; to be technically accurate, “4K” really means 4096 x 2160 and “8K” means 8192 x 4320.
Here’s a PDF from a SMPTE conference in 2012 that dives deep—maybe too deep—discusses the concepts of simple acuity, hyperacuity, and Snellen acuity. This is an extremely technical paper and I’m certainly not urging that you plow through it. It’s filled with stuff like this:
Oh, that Snellen! The guy who came up with the standard eye chart!
Bottom line, there’s a basic and yet quite satisfying viewing experience for which immersion is not the point, and when you live in a small apartment, immersion might not even be possible—the angles and distances don’t work out. You just want to see the numbers on the election returns, or the soccer ball, or the hockey puck.
And perhaps more importantly, much of the content out there is barely ‘1K’—HD, which, by the way, is a very nice image to look at from across the room indeed. And if it’s upsampled to a higher resolution, that’s a procedure that scientists are improving on, but you still can’t manufacture pixels out of thin air. Real resolution is the resolution you start out with.

After hearing about a short film promoted by Apple (because of course it was shot on their flagship product), I winced after I rolled it on YouTube. It was in a vertical format, not the landscape aspect ratio that the world has experienced in movie theaters and on television screens pretty much since there were movie houses and TVs.
I joke about it a lot, but vertical videos for telling stories is just not a great idea. I should pause here for thousands of people who say “but the modern stories are Instagram stories, and they are verticals!! Books are verticals! People are now watching this sort of content on their phones and only on their phones, and that’s on a vertical screen!”
Even on my phone, watching the Apple video, I craved seeing what was to the left or to the right of my screen. And no, I never have similar cravings for “what’s above or below the frame” on landscape (wide) presentations. Maybe it has something to do with our eyes being mounted in our heads in landscape orientation.
And then I watched a clip or two online from EuroNews of their coverage of the coronavirus crisis. They’ve decided to visually split the difference, doing their videos in square format…and these short clips are not carefully crafted packages where a reporter speaks the who what when and where of the story…a bullet-point-like subset of that information appears on a bunch of large-type overlaid titles, almost always accompanied by what some editor thinks is appropriate music (that they have a license to use.) Oh, sad music for a pandemic…cartoony Benny Hill-style music for someone doing something embarrassing for the cameras….faux-majestic for coverage of the Royals.
These blip-news-verts are disposable, vapid, can be cranked out by minimum wage toilers in edit rooms, and are instantly forgettable. And if that’s what visual journalism is today, is there anyone who really wants to label that good journalism?
So what is good journalism in this time of fast and vertical? I do have one link for you: here’s some good reporting on urban issues from a guy in Vancouver, good enough that his work has been picked up and showcased by the CBC, Canada’s national public network. If you like that one, he has some others on the YouTube.

It’s a cold and clear day here in Atlanta, which is very different from this YouTube frame (life this afternoon) of an eastbound train in Fostoria, Ohio.
This is actually a nice high-resolution camera, but like many digital sources in the tubes of the internet, it’s on a bit-budget. If the picture is relatively static‚ if relatively few pixels change from one thirtieth of a second to the next, then the camera system only needs to transmit the changed pixels, and can devote more of its bandwidth to transmitting more fine details of the part of the picture that isn’t changing moment to moment.
Throw a flurry of snowflakes—or a ton of confetti at a political convention—into the picture, and it dumps down to a much lower resolution, because more is changing from frame to frame, and the system has to do its best to depict that.
It’s amazing how low-def high-definition tv can get when the finite number of bits that can fit in the pipe are consumed by tiny flickery fast-moving things.

I don’t think this is an average Wednesday because I’m not sure we have those anymore.
- The market continued its downward trend in response to Coronavirus concerns and…wait, I’m being told that the President said it was going down in response to the Democrats debating. Hmmm. Let’s stick with that first explanation.
- We were told it would rain heavily in the city this afternoon; it kind of misted and spat for the most part.
- We ran (no, not literally) into our niece in the Trader Joe’s parking lot. That was a nice perk of the day.
- The President appointed a guy to run the US Coronavirus response. A guy whose policies led to an HIV crisis in Indiana in 2015 because he sure didn’t want Planned Parenthood to…uh, do what it does so well. You know, our vice-president.
- We quickly turned away from that and watched Survivor. Read into that what you will.
- Later that evening, we watched coverage of the global health crisis and the US’s reaction to it on BBC World News, CBC’s The National and France 24. Somehow reassuring to be reminded that we’re all in this together. For the most part.

The South Carolina Democratic Debate. Seven people on stage.
The CNN analysis immediately afterwards: hey, eight people!
Although a bit of light was shed, the analysis by the eight about the performance of the seven was: hey, why weren’t those moderators at CBS doing a better job? You can’t just let them all talk at once!
Yeah, that never happens on CNN.

I’ve been spending a lot of this evening repairing the $5 Raspberry Pi Zero W computer I use to put standard definition images up on an old Sony Trinitron monitor in my office. Why? Because (besides the cool factor) I want to remember what standard definition—the old television, before everything went 16×9 and HD—felt like.
And did I mention this was a $5 computer?
Which is all well and good until I make a minor mistake, or the internet makes a tiny mistake, or the Raspberry Pi’s operating system makes a tiny mistake, usually in the midst of backing up or restoring zillions of tiny Linux packages—chunks of code—that make this 2.59 inch x 1.2 inch circuit board do its magic.
And then, it’s dead. Nothing happens. No lights on the circuit board. But I don’t despair, I plow through a convoluted multistep recipe that involves scrolling through screen after screen of stuff that looks like this:

..and after a great deal of holding-one’s-mouth-correctly, it comes back to life, as if nothing has happened.

…and the frankly spectacular arches that now cover the North and South terminals dropoff/pickup lanes at Hartsfield Jackson Airport. At night, they’re a cascade of LEDs (that yes, of course, can change colors, just like the top of the Empire State Building). The canopies also of course deflect some of the heat and all of the rain on the summer afternoons like we have here.
But I suppose the real dead giveaway is that I have a phone that can take pictures this nice at night. The future! Welcome!

At the southern end of Lake City Way, past seemingly endless used car lots and pot and vape shops, lies a culinary promised land:
Really yummy food in a very unpreposessing setting. Nice way to end our visit.

I really need a picture for this post to be complete, but I’ve seen 6 or 7 apparent van conversions out here in Seattle where people have crafted various rolling behemoths into their day-in, day-out home. Often parked near the ocean or in an out of the way park, these mobile homes range from the deluxe to the scavenged-looking, and for some reason they seem to include one or more large dogs along with the young couple who have decided to live The Life Nomadic.
Today down by Golden Gardens Park I spotted an early-2000s Ford Van that had (to me) an obvious provenience: it was a former TV News ENG truck, probably one with a large mast (now gone) on top. Its initial conversion, from empty box to one brimming with TV gear, was done by Frontline Communications of Clearwater, Florida. Easy to tell: it still had the Frontline stickers and the large panel on the right side that engineers plugged cable after cable into…and the platform on top that they would climb on to point the antenna toward the microwave receiver at the station.
Now, it would seem, it is a home. Dog included.

I’m of a certain age that I know enough people who discovered communicating through computers and the internet roughly on the same timetable as me and for many of us, there was a prime moment when the thing called the blog was in fact, the thing. The idea that you could have your own domain and write whatever you wanted and you could reach a potential audience of untold…well, probably not millions. Probably not even thousands. But an audience! Humans! Clicking and reading!
Just as you are doing right now.
Sure, all kinds of much more powerful and flexible and sometimes quite Orwellian services made it easier to share what was on your mind or in front of your eyeballs at any given moment with a quick flick, twitch, or poke, but for sheer purity of presentation, this here blog thing is not a bad way to go.
But it’s not the late 1990s anymore, it’s the early 2020s, and the things people think about and the stuff they might want to “put out there” have doubtless changed. So I spent a few minutes scrolling and reading the words published by friends like Nancy and the fabled Kayak Woman, and of course, my favorite for so many reasons, Sammy. They put a lot into these discrete online collections of who they are, and as I read, I feel as if I’m spending a moment with them at the end of their day, as they pour a thought or two into a WordPress template and hit ‘publish’ with great satisfaction.
And, hmm. What’s tonight’s topic? What’s new in their worlds? Maybe their blogs are not so different over the years in tone and focus…just the particulars of the story have changed. And the resolution of the cameras have improved.
But topics? The continued decline of American society. The magic of a place close to their hearts. The triumphs and challenges of family and other loved ones.

Okay, this is the first democratic debate (of this campaign) I watched.
And there were indeed “fireworks”, as cable pundits would like to say.
First there was Mike Bloomberg, an easy target. In the first few minutes, Bloomberg was eviscerated by Elizabeth Warren over his stop-and-frisk policies and his general billionariness; she later challenged him on an ambiguous number of harassment suits held under NDAs. How many, Mike? Will you release the women from the NDA component? Nope, he wouldn’t.
After a Telemundo questioner pointed out that Amy Klobuchar was unable to name the President of Mexico in an interview, Pete Buttigieg piled on to Klobuchar making a not-invalid case about being prepared and informed. The senator looked (to me) as if she was more than prepared to violently remove the head of the former South Bend mayor.
Now they’re thrashing through climate change.
My takeaway at this hour remains: Elizabeth Warren is so smart. And I really like smart candidates and presidents.

There was a restaurant around the corner from our Atlanta home for a while with that name, with that exact punctuation. Yes, indeed, they had fish!
But I’m using the term this evening to mean that we have wandered away from Positively Atlanta and we’re looking here at Puget Sound, which means for many intents and purposes we’re looking at the Pacific Ocean. We’ve gone coastal, western style.
It was gusty and cool but very bright and sunny today. The sound had those windsurfer paraglider whatchamacall-them (the red shape out just above the water) along with Washington State Ferries and tethered sailboats and people walking their dogs along the pebbly coast. Quite idyllic, and the sunshine on the Olympic Mountains (in the distance, off to the west of Seattle) was just our visual icing on the cake.

Spent some quality time this afternoon with nephew the elder, who is taking an undergrad course in Music Synthesis and Recording. This means he’s using technology to capture performances, to edit and quantize audio tracks, to layer beats and rhythms into something we’d call music.
He said today that the course started with early electronic music recording and his dad said “ah, like the gramophone?” And he got a blank look in return.
No, the early history of electronic music starts, well, in the late sixties early seventies, with those Wendy Carlos-operated cobbled-together systems (like the Moog synth), laden with patch panels and dangling cords and lots and lots of knobs, all to emit very very rudimentary tones. Sine waves and sawtooths at play in the garden of Mozart’s delight.
And, appropriately, the plug-in-rich music creation software our nephew’s learning on has some modules that actually emulate that functionality, right down to the simulated rack mounts and patch cords.
He’s learning a jargon and techniques rich with allusions to the past old ways, and I sure find it entertaining to see him start to pull past tech and present tech together to create his future.

I’ve been through Tacoma, Washington many times, at speed, on Interstate 5, where it seems like an industrial blur fronted by a Jupiter 2-shaped building called the Tacoma Dome perched on the edge of the freeway.
But today we went into Tacoma proper, to the Museum of Glass, a modern building with a conic cylinder of glass and steel along the waterfront. Really nice museum, with a ‘hot room’ (right in the conical part) where trained artisans pull molten blobs out of furnaces and shape them into decanters and pitchers and elegant glassware.
And in their very fine gift shop, where you can buy decanters and pitchers and elegant glassware and earrings, they had copies of Grit City Magazine for sale, shown here.
So…Grit City? Is that really what Tacoma’s called? Turns out it’s a long story, and this Grit City Magazine article tells it well, and, spoiler alert, it has nothing to do with cornmeal.

I had heard from, well, the internet and social media and all the modern ways that people “hear” about things, that the Ballard neighborhood of Seattle had a museum of all things Danish, Norse, Swedish, and Finnish…a veritable Nordic Museum, the National Nordic Museum, in fact.
The clean-lined modernist structure in Ballard held a collection of artifacts and stories of those who immigrated from the northern latitudes in Europe and found themselves scattered across the American landscape but (as one of the stories on the museum’s screens told), many were especially happy to end up in the Pacific Northwest, with all of its familiarities: climate and landscape and ways to make a living.
The museum’s neighbors include a lot of businesses and infrastructure that connect, directly and indirectly, to the sea, and that’s still a part, although a lesser one, of modern Seattle.
Seattle in 2020 is a more interesting and diverse city, with immigrants arriving from more parts of the world, and it was interesting to browse a presentation of what is just one immigrant group’s stories that forms the American mosaic.
Also, where else would you see a nyckelharpa on exhibit or see the dubious claim that rabbit-ear antenna was invented in Sweden…or is it Finland…or Denmark?
