Went with the family to see Space Shuttle Endeavour and a Pixar-themed exhibit on computer animation at the California Science Center.

The 6YO loved the Pixar exhibit, which broke down all the steps to creating a computer-animated movie into separate hands-on centers where you could do things like…

  • Apply different textures and bump maps to an object.
  • Rig a character for movement.
  • Change the lighting of a scene (real or virtual).
  • Define a shape in a 3D grid and watching the computer rotate it (way too much time on this one).
  • Create your own stop-motion animation by moving an actual desk lamp.

The only way we got him out was to point out that the museum was closing, and we only had 10 minutes left to get to the touch pools he’d said he wanted to visit. As it turned out, the pools shut down about two minutes before we got there, but staff was willing to let him look at the starfish. And we did catch the last desert flash flood simulation of the day.

As for the shuttle…he wasn’t impressed. He insisted on taking the simulator ride, but the real thing? I guess it’s old news when the whole fleet’s already been shut down by the time you start hanging onto long-term memories. 🤷

Admittedly, a big aluminum hut isn’t as suitable a viewing area for Endeavour as open space in broad daylight, surrounded by an enthusiastic crowd. Though that might have been the fact that it was my first time getting up close. On the other hand, this time I could see both sides. Heck, I could walk under it!

There is a new building in the works, where they’ll be displaying it with one of the external tanks in launch position. I’m sure it will lead to plenty of cartoons and movies where someone goes to the museum, breaks into the shuttle and blasts off.

I couldn’t make the building line up with my memories of visits when I was younger, back when it was the Museum of Science and Industry. The only thing I could match up at all were the wall facing the Exposition Park rose garden, and some of the buildings by the parking lot (a sunken structure now, but I remember it being flat).

Then again, what I remember are specific exhibits more than the layout: a big math/physics exhibit, a chicken incubator, and a multi-screen cartoon about energy sources and engine types called “The Water Engine.” (Each screen has a character talking up internal combustion, flywheels, mag-lev, electric, etc. I still quote the Peter Lorre-inspired fuel-cell scientist saying “And then…we burn the hydrogen!”)

It turns out there’s a good reason nothing fit my memory: They tore down the whole building in the late 1990s, preserving only that one wall!

I liked Rogue One: A Star Wars Story quite a bit. Despite having a very different tone from either the original trilogy or the prequels, it’s still recognizable as a Star Wars film, and successfully weaves in and out of the events leading up to A New Hope.

There’s a somewhat odd setup for where they actually find the Death Star plans, though. SPOILERS after the cut:

An odd contradiction: People are turning away from science as a way to understand the world, even though we keep using more and more advanced technology which is invented using that scientific knowledge.

What if it’s that, in terms of Clarke’s Third Law, the technology we use is sufficiently advanced that it might as well be magic?

It’s easy to understand how a toaster works. Electricity goes in and heats up the wires. Or an incandescent light bulb, or an internal combustion engine. Anything that’s primarily mechanical, you can understand intuitively: “Oh, this part moves that part, which moves that part, and then I kind of get lost, but eventually it gets to the wheels.”

But a computer chip? GPS navigation? Downloading and playing a game on a mobile phone? These things might as well be magic to most people who use it. At the consumer level, GPS is a black box that tells you where you are and how to get where you’re going. But underneath that, it’s satellites, relativity, radio transmitters, radio receivers, computer software, circuitry, mathematics, rockets, data transmission, traffic detection, mapping software…so many pieces that take some degree of studying to really understand.

If our technology is “magic,” it ceases to be a reminder that science works, and may even encourage belief in things that don’t have clear mechanisms and supporting evidence. The very success of science at making possible the technology we use everywhere could, ironically, be discouraging people from believing in it.

*I wrote this three years ago. I’m not sure why I didn’t post it at the time. All I had to do was tighten up the wording a little bit. And sadly, the situation hasn’t improved.

That took a lot longer than I intended.

But I’ve finally made all of Hyperborea.org run over HTTPS.

It’s been possible to view the whole site over HTTPS ever since I turned it on for the admin area of this blog years ago, but I left HTTP as the canonical URL and didn’t redirect anything until I updated the Les Mis section, and later this blog. Now, any page you visit on this entire site should load over an encrypted connection.

(Well, any page except for the old Dillo RPMs page, since that minimalist web browser still only has experimental HTTPS support.)

The problem is when you have decades of hand-crafted web pages to go through, it can take a while to make sure everything embeds only secure or same-origin content. Every image, every script, every video. I had to update lots of absolute links, remove some widgets and ads, update other widgets, embedded videos and metadata…and just a bit at a time in my spare time.

Finally I switched on the redirects this morning. Even that took longer than expected, because I’d forgotten that mod_rewrite rules in a directory override any parent directory’s rules, so I had to copy the HTTP-to-HTTPS rewrite rule to each folder that had its own rewrite rules. Then I had to fix the interaction between mod_rewrite and ErrorDocument that was causing custom errors to redirect to the error template instead of loading it behind the scenes.

I received a scam email claiming to be from the IMF, all about who to contact if you fell for an advance fee fraud scam claiming to be from the IMF. All you have to do to get your money back is send your info and $150 to Barrister so-and-so to set up an account, just contact this GMail address…

I recently dug out my old Samsung Galaxy S4 for some Android testing. I replaced it with a Nexus 5x last fall, and for the most part I love the newer phone, but there are a few things that I really miss about the S4.

  • The size is perfect. It’s literally as big as it can get and still be comfortable to use one-handed and fit in my pants pocket. The Nexus 5X is barely 1/8″ wider and 3/8″ taller, but it’s just enough that I can’t quite reach the whole screen with my thumb. I have to loosen my grip until it feels like I’m going to drop it, which means I’m extra motivated to keep it in the case, which makes it even bigger…
  • The Galaxy S4 display is polarized diagonally, so I can use it in landscape mode while wearing sunglasses. This is helpful for things like daytime GPS navigation. The Nexus 5X is not.
  • The volume buttons are positioned out of the way of the middle, making it easy to clip on a dashboard mount.

Those are three things that the Galaxy S4 does better (for me, anyway) than the Nexus 5X. They’re all form factor. Of course since giant smartphones are all the rage these days, good luck finding another one that’s just the right size for my hand.

Otherwise, I love the Nexus 5X’s display, the up-to-date Android OS without Samsung’s modifications (and knowing I’ll actually get security updates), the camera, the convenience of the fingerprint sensor, the speed, and just about everything else about it.

I wouldn’t go back. I considered setting up the S4 as a dedicated GPS until I realized that it wouldn’t be able to get traffic data without a SIM card. (Maps can store the actual maps offline now, and GPS works independently of cell service.)

But if Google releases their next Nexus device in a form factor just 3/8″ shorter, I’ll be tempted to upgrade early.

Opera RingThe reporting is a bit confusing, but it looks like the Opera web browser has been sold to a Chinese consortium. The group wanted to buy the Norwegian company outright, but the bid failed, and they fell back to an alternate deal.

According to NewsWeb:

The following business units of Opera will be included in the Transaction:

· Mobile Browser, including Operator Co-brand solutions
· Desktop Browser
· Performance and Privacy Apps
· Opera’s technology licensing business outside of Opera TV
· Opera’s 29.09% ownership in the Chinese joint venture nHorizon

The Consumer Business will be reorganized into a separate company structure. For
clarity, the following businesses are not included in the Consumer Business or
the Transaction:

· Opera Mediaworks
· Opera Apps & Games (including Bemobi)
· Opera TV

It’s a shame to see Opera broken up and dispersed…but in a way, that already happened years ago. When they switched to WebKit in 2013, they lost what made them unique and (IMO) valuable: They’d been a solid third-party (well, fourth-party) that helped keep the web from collapsing back into a monopoly. Within a year the community portal was gone as well.

Since then I’ve only bothered with the desktop browser occasionally when I need to test multiple sessions at once. I used to keep a copy on my phone for times when I was stuck on a slow connection, but these days the cell network in my area is a lot faster. When it gets slow, it’s also unstable, so compression doesn’t help much.

VivaldiI think I will check out Vivaldi again, though. Founded in part by Opera co-founder Jon von Tetzchner, it started as a new home for the Opera community. When I first checked out their browser, it was a really rough preview, but it’s at 1.2 now. While it’s using Blink as the rendering engine, they seem to be trying to innovate through the UI instead, with a heavy emphasis on customizing everything.
