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.
"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.
Catfood WebCamSaver is a Windows screen saver that streams live views from random webcams around the world. Download for Windows. You can choose to display 1, 4 or 16 webcams at the same time, and WebCamSaver fully supports multiple monitors. Catfood WebCamSaver was first released in 2004.
When you install Catfood WebCamSaver a shortcut is created to Screen Saver Settings. You can search for Catfood WebCamSaver Settings and run the shortcut, or open Screen Saver Settings directly (on Windows 10, Start -> Settings -> Personalization -> Lock screen -> Screen saver settings). From Screen Saver Settings make sure that Catfood WebCamSaver is selected and then click Settings. On the Windows settings dialog you can also choose how many minutes to wait before starting the selected screen saver and if the login screen should be displayed when the screen saver exits.
Catfood WebCamSaver Settings has three tabs:
Under Description choose if the description of the webcam and the local time if available should be displayed. Click Font to pick the font, color, and optional outline color to use for the description and time.
Under Display choose the number of webcams to show at the same time (1, 4 or 16), how often to switch to a new webcam and how often to refresh the webcam image.
Under Offline Display you can choose a fallback screensaver to start if the Internet is not available.
Please note that recent releases of WebCamSaver will delete and recreate the webcam list on install. This means you will lose any customization of the list on upgrade. See the import and export instructions below to back up any changes you have made.
The Webcams list shows the current library of webcams. Click the column headers to sort (and click again to sort in the opposite direction). You can enable to disable a specific cam using the checkbox in the list.
Click Add to enter details for a new webcam.
When a webcam in the list is selected click Open to launch the web page associated with the webcam, Edit to update details or Delete to remove it from the list entirely.
Click Delete All to remove all webcams from the list.
Click Enable All or Disable All to toggle the checkboxes for all webcams in the list.
You can save your customized list by clicking Export and restore it by clicking Import.
If you prefer day (or night) scenes you can set a local time range here. If this option is enabled webcams where the time zone is unknown will never be displayed.
Click Proxy Settings to configure a proxy server.
Catfood WebCam Browser is a companion application installed with WebCamSaver. When you open WebCam Browser it will start showing a random webcam from the library.
Pick Cam opens a window where you can select a webcam to view from the full list. You can sort the list (click any column header, click again to sort the opposite direction). There is also a filter that only shows webcams matching text that you enter.
Random Cam will select a new webcam at random from the list and start streaming images.
Control Cam launches a URL where you can control the currently selected webcam (if available).
About shows the version and copyright information for the application.
Catfood WebCamSaver requires version 3.5 of the .NET Framework. On Windows 10 you need to go to Programs and Features and then Turn Windows features on or off, find .NET 3.5 and enable it. The installer for Catfood WebCamSaver is not currently digitally signed. You may get a warning when downloading and again when installing which you will need to ignore to proceed. I plan to fix both of these installation limitations at some point in the future.

“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.” Lynne

So I disagree with this but it's interesting and well argued. A better idea is my life expectancy weighted voting plan.
NYT finally twigs.
In one of the cases, filed Sept. 4, plaintiff Maria Infante seeks $50 million and class-action status after a San Francisco parking enforcement officer wielding chalk on a residential street gave her a $95 ticket.
The second case, filed the same day against San Leandro, demands $5 million for class members whose tires were chalked to financially benefit the city.

A small WebCamSaver update.
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?
ITHCWY: Thanks for your time today. I'm sure our readers feel that all of their questions have been cleared up.
ECE: You're welcome.
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.
