Should there be a constitutional amendment for tire chalking?

Limantour Spit
There is a shorter trail through the dunes before you get to the beach which we attempted a couple of years ago. The vegetation is spiky and unforgiving for small people. Better option is to hit the beach, turn right and walk as close to the end as you can. Five mile flat round trip. We saw harbor seals and one very decomposed whale.
Hike starts at: 38.025765, -122.884455. View in Google Earth.

Another visit, on another beautiful day. Spotted a seal and I think a grey whale.

Facebook Interoperability
In TechCrunch today Josh Constine gets friend portability for Facebook almost right:
"In other words, the government should pass regulations forcing Facebook to let you export your friend list to other social networks in a privacy-safe way. This would allow you to connect with or follow those people elsewhere so you could leave Facebook without losing touch with your friends. The increased threat of people ditching Facebook for competitors would create a much stronger incentive to protect users and society."
The problem is having a list of friends does me no good at all when none of them are on Google Plus, Diaspora or whatever.
What we need is legislation that forces interoperability. I can share with my friends via an open protocol, and Facebook is forced to both send and receive posts from other networks. This would actually create an opportunity for plausible competition in a way that a friend export could never do. Social networking should work like email, not CompuServe.

Tire Chalking Constitutional Amendment
We haven't passed a constitutional amendment since 1992. I have an idea or two, but given the length of the hiatus maybe we need to warm up with something easy.
The Sixth Circuit Court of Appeals recently ruled that that chalking car tires to detect illegal parking violates fourth amendment protections against unreasonable searches and seizures. Civilization is collapsing a little in Michigan, Ohio, Kentucky and Tennessee.
Parking spaces are a limited resource and a fundamental role of local government is figuring out how to carve this kind of resource up equitably. Time limited spots are a pain, and if you don't like them you could complain to your representative or even run for office on a parking anarchy platform. Maybe you'd win and then good luck finding any parking at all. But if the courts decide to open up a tragedy of the commons enabling loophole then it must be time to slap them down.
The 28th amendment should explicitly allow tire chalking for parking enforcement. With the momentum from that we can start fixing some real problems.

Conway's Game of Death.
The site I had been using for global cloud cover images in Catfood Earth abruptly shut down recently so I've had to scramble to build a replacement service. This is live now and updates are available to download for Windows and Android.
More details about putting together the best possible clouds image for Catfood Earth here.

Catfood Earth 3.46
Catfood Earth 3.46 is now available for download. Catfood Earth for Android 1.70 is available in the Google Play Store and will update automatically if you already have it installed.
This follows hot on the heels of the last release as the new clouds layer service running on this blog can update far more frequently than the source used prior to 3.45. You will now get a fresh helping of clouds every hour! Unrelated to this release I've improved the quality of the clouds image as well. If you're interested you can read about this in exhaustive detail here.

Improving the accuracy of the new Catfood Earth clouds layer
Last weekend I rushed out a new version of Catfood Earth because the clouds layer stopped working. I'd been using xplanet clouds which published a free 2048x1024 image infrequently and for some reason the site has vanished (probably because it was based on data from the Dundee Satellite Receiving Station which has apparently closed). The University of Wisconsin-Madison Space Science and Engineering Center makes global cloud data available for free for non-commercial use so I plugged this in to get Catfood Earth up and running.
Clouds started working again last Saturday but they were slightly out of position. With a pixel on a HD screen being up to 13 miles this isn't ideal. I hope nobody is using Catfood Earth for weather forecasting or anything too serious but this bothered me enough that I had to fix it. From today the clouds layer is as close to perfect as I can make it.
Mostly for my own sanity in case I ever need to fix this again here's the process.
I use the globalir product because it covers both day and night. This is available in a number of resolutions and you just need to download a set of tiles and stitch them together - I'm using 4096x4096 as the source for the new layer. Catfood Earth uses equirectangular images which have a 2:1 aspect ratio so to start with I resized this less at the equator and more at the poles and got an image that was almost right.
The source image is Spherical (or Web) Mercator which is useful for Google Maps but not right for Catfood Earth. I found a Stack Exchange post which pointed me in the right direction - use GDAL (Geospatial Data Abstraction Library) to transform the Mercator image to equirectangular by tagging the corners and then warping it. This got me closer but it still wasn't right. More googling led me to a post by Robert Simmon with a gdalwarp tip to use -te and -te_srs to force the output to match the dimensions of the input.
The last problem is that the Mercator image doesn't reach all the way to the poles. In this case there is no alternative but to invent some data and so I flip the top and bottom 50 pixels to cover the gap. You can see this if you look carefully but as this region is rendered over ice in Catfood Earth it won't make a difference in practice (and the old image used this trick as well for a greater proportion of the clouds).
One final visual tweak is to drop the lowest intensity pixels which end up blurring out the background in Catfood Earth. You can adjust the transparency and color used to render the layer to suit your tastes (the default is 50% transparency and a gray color for the clouds which I think strikes a good balance).
I also increased the frequency of updates so a new image is available every hour. I said last week that an advantage of this new system was that I wouldn't need to push a new version of Catfood Earth to tweak the cloud logic. That's partly true - you'll get the new improved image with the current version, but I stepped down the update frequency to once a day when I started using xplanet clouds. There will be another update soon to the Windows and Android versions to switch to hourly updates.
Updated 2022-11-05 12:28:
A couple of updates here. The first is that RealEarth started watermarking images over a certain resolution and/or usage volume. You now need an API key and potentially to pay based on usage. More details here. I managed to stay in the free tier by asking nicely and scaling back to HD. The clouds download is still 4k but this is upscaled from a HD version.
Grabbing the latest image (for globalir) worked until sometime in October and then the tiles stopped lining up correctly. I'm not sure what changed, I guess that 'latest' used to mean the latest composite and now means the latest data for any given tile regardless of it is the same time as the others. I just fixed this to use the latest complete image (this API provides available dates and times, and then you need to use the date and time in the globalir call to get a working composite image).
Updated 2023-09-03 01:03:
There is now a video made from the last 48 hours of cloud images here, updated hourly. The video skips the step of dropping low intensity pixels so you get 100% of the cloud cover.
