This is the third batch of crystals from our National Geographic Mega Crystal Growing Lab kit (see the previous two).
I have been meaning to experiment with Adobe's Super Resolution technology and this seemed like a good project for it. The video below has the same timelapse sequence repeated three times. If you're not bored of crystals growing yet you soon will be (don't worry, this is the last for now). The first version is a 2x digital zoom - a 960x540 crop of the original GoPro footage. The second version uses Super Resolution to scale up to full 1920x1080 HD. Finally I added both side by side so you can try to tell the difference.
Super Resolution generates a lot of data. I tried to use it once before for a longer sequence and realized that I didn't have enough hard drive space to process all the frames. In this case I upscaled the 960x540 JPEGs which went from 500K to 13MB, quite a jump. I don't see a huge difference in the side by side video though and wouldn't go through the extra steps based on these results. It's possible that going to JPEG before applying super resolution didn't help with quality. It's also possible that Adobe doesn't train its AI on a large array of crystal growth photos so I can imagine it might work better for a more traditional landscape timelapse. I'll test both these hypotheses together the next time I 10x my storage.

We have tried Common Core, Race to the Top, Charter Schools and No Child Left Behind. The US ranks #37 in math according to PISA, behind China, Russia, and Estonia. And we're not making any progress:
"Test scores on the federally funded National Assessment of Educational Progress—known as “the Nation’s Report Card—have been stagnant for the past decade. The scores of the lowest-ranked students declined."
Of course poverty, ideology and unions all play a role here. But none of these challenges are unique to the US. I think the problem is sports.
Something that has always bothered me as I travel around America is that most schools primarily identify themselves by their sports team. Home of the Tigers! Or whatever. What must that do to the majority of non-Tigers turning up for school every day. Nice work on the math test but the only thing we're actually proud of is the football team.
Sports are important of course, to build teamwork and for exercise and as a future career for a tiny minority of students. Nearly everything else the school does is far more impactful.
An important and easy (although likely unpopular) Federal education reform would be to force schools to promote all extracurricular activities equally. Schools could choose to promote nothing and just be a school (like the vast majority of the rest of the world). Or they could give each activity, club and society an equal share of their jumbotron to represent the full diversity of the student body.

Customer Reviews
“We LOVE your screen saver. I've seen others try this idea, but never quite seemed to get it right.”
Buddy King
“The other day I watched as a middle aged
couple in Japan took photos of the changing orange leaves along a calm street. I saw another couple, some tourists,
digging for their sunscreen on the beach in Kona, HI.”
MIT Center for Future Civic Media Blog
“I've been fascinated by your ‘saver’! It strikes me that so many different places & cultures seem to share some
common traits, so that each saver appears to be both familiar and exotic.”
Tom
“Very nice screensaver. One of the best I've seen.”
Andy Cant
“As a live webcam afficionado, I believe your product is the best, offering high quality resolution, reliable transmissions,
a nice blend of everyday street scenes with landscape views, and multiple cam shots filling the entire widescreen page.”
Oliver Garrison
“The new version is wonderful. I love being able to sort by age (so I'll never miss a new addition), and I love how easy it is
to select my favourites. Basically, I love everything about it. It's so much fun, and brings so much variety to the screen. I have
my favourite cams - The streets of Narbonne, that crazy Japanese wind-speed screen, the flag-filled car-park of a Dutch retail park -
But it's always fun to leave this screensaver on random and let it transport me to a completely new place.”
James
“I have to say that I am enjoying the sights that I am able to see on the web cam. The views are very clear and they are never
the same shots. I like being able to show off my new screensaver. Thank you.”
Isaac Adel
“Hi, I just love your web cam, I enjoy looking around the world at places I have never been to. Whoever thought up this idea, gets a 10/10 from me.”

As a public service we interviewed every coronavirus expert from every hospital and public health department to get definitive advice on how to think about COVID-19 and navigating the current state of the pandemic.
ITHCWY: With the rise of the more infectious Delta variant, how should the vaccinated approach returning to bars, restaurants and even the office?
ECE: Great question. I think people should be asking themselves two questions. First, how vulnerable are you to infection? Do you have comorbidities brought on by having been alive for more than a few years? Do your cells accept or reject spike proteins? Second, what is your personal tolerance for badly quantified risks?
ITHCWY: What about families where the parents are vaccinated but there might be younger kids who aren't eligible?
ECE: Families are in a tough spot. As well as considering your own unknown vulnerability and appetite for risk, parents should also consider how likely their children are to get infected and the various articles they have read about unprecedented increases in vanishingly rare side effects that are overwhelming health providers at unconcerning levels.
ITHCWY: Your education and career have prepared you to quantify absolute and relative risks for infectious diseases, correct?
ECE: That's right. Not sure why you'd be interviewing me otherwise.
ITHCWY: Let's move on to outdoor risk. Last year there was a lot of talk of maintaining six feet of separation. Is this still the best advice?
ECE: It was the best advice we had available at the time. It turns out that six feet came from a Japanese marketing campaign in the '60s and has been passed on from public health expert to public health expert until the origins were entirely forgotten. The Japanese character for 6 looks a lot like a man standing to one side while a virus particle lands harmlessly next to him and so it kind of stuck. Cute, but it turns out there is little data to suggest it should be 6 feet rather than 4 or 20.
ITHCWY: So in 2021 what sort of distance should we leave when passing others?
ECE: It's a heavily populated planet. If you're moving further away from one person you're getting close to another. Instead of absolute distance I'd consider if that total stranger is vaccinated, what their hygiene habits are like, do they look like they'd cough into their elbow or directly at your face. That kind of thing. And as always you should consider your likelihood of infection from that specific person as well as the risks you've already taken and may yet take that day.
ITHCWY: More and more businesses are installing carbon dioxide sensors. Do you think this is a helpful trend?
ECE: As we all know ventilation is incredibly important in an indoor environment. It's also important that we use common sense. If you think 400 parts per million is a good level of CO2, good for you. If your spider sense thinks it should be more like 20%, knock yourself out.
ITHCWY: Is there a level of CO2 that would make you, for instance, stand up and leave a restaurant and go somewhere else?
ECE: Yes.
ITHCWY: Thanks for your time today. I'm sure our readers feel that all of their questions have been cleared up.

A while back 2TB of storage seemed like plenty. Ooops.
It doesn't help that I'm a digital hoarder. I have everything from email mailboxes from the early 90s to obsolete Android virtual machines that will never run again. I've been forced to do something about it by filling up my backup drive.
My current backup strategy is to send everything to Google Drive. And then send all my pictures to Amazon Photos (free with Prime!). And then backup everything to an external drive (using my VSS tool) every month and stick it in a fire safe because Google and Amazon do not care about my files like I do.
I wrote a little utility to dump some stats to help me accept the problem and then do some tidying. Here's storage over time (imperfect, based on earliest of creation and last write time):
Some of that is driven by ever better cameras and increased willingness to shoot 4K video. Some of it is crazy projects that I forgot to tidy up after, like making a daily timelapse movie from a nest cam.
Here's a breakdown by file type:
Mostly media. New resolution, when I take 500 photos of my thumb I should delete all but the very best right after uploading instead of saving them in case I want to make some kind of thumb-animation later.
The most useful thing the utility does is dump out each folder with more than 1GB of files. That found a lot of cruft hiding in unexpected places (bye bye every frame of the 2017 eclipse that I accidentally left in Google Drive instead of my dedicated time lapse disk). I might improve this over time, but all of the above is available now as folder-insights on GitHub.

I just voted no to recalling Gavin Newsom. He probably shouldn't have had that mid-Pandemic party at The French Laundry, but I don't think that rises to the level of getting kicked out of office. I think we can wait for 2022 to pass judgement on his tenure.
The polling seems fairly tight right now, which is a little surprising given the Democratic lean of the state. I was tempted to leave the tedious second question unanswered, or write something stupid in, but it's possible that Newsom loses and we have to pick a new Governer. I backed Kevin Paffrath because he's going to fix homlessness in 60 days and he's the leading Democrat in the polls (and I don't believe he's going to fix homlessness). I don't want Newsom to lose but if he does I'd rather avoid the bear renter or talk radio climate skeptic.
"The vote is expected to come down to whether Democrats can mobilize enough of the state’s enormous base to counteract Republican enthusiasm for Gavin Newsom’s ouster."
But everyone is getting a postal vote. You don't even need a stamp. "Mobilize" is a bit of a stretch. If Newsom ends up sacked it's because he partied while the rest of us were bleaching our broccoli.

A timelapse of four containers growing crystals from the National Geographic Mega Crystal Growing Lab. The sequence was shot over two weeks (one frame every four minutes, running at 60 frames per second).
It should have taken less time. They recommend a growing area that is at least 68 degrees. This shouldn't be a problem with most of the country suffering record temperatures under heat domes if not actively burning in record breaking wildfires, but San Francisco is experiencing its coldest summer in more than five decades so two weeks seems like the minimum.
Other than not attempting to grow crystals in San Francisco, the other lesson learned is that you really want to use the two silicone cups included in the kit. We tried a pint glass that just grew fuzz (possibly due to the age and pitted nature of the glass) and a jam jar that grew cute small crystals that then made a decent attempt at escaping down the outside. I think three weeks and it would be a full J. G. Ballard situation.

Second batch. This time shot from above. It's still cold, so this is three weeks, 5 min interval and 60 frames per second for the timelapse:

Third batch. We're well into September but San Francisco is still bathed in fog. This is still at 5min per frame, but only took two weeks as I moved the lights closer in. For this timelapse I experimented with Adobe Super Resolution so the video has the same sequence three different ways (I wrote a separate post on the Super Resolution experiment).
