The Moray Eel’s 2nd jaw is called a pharyngeal jaw. They use it to pull down prey captured in the front of their mouth, further down into their esophagus. It’s creepy, and it’s true! Check out this video of the jaw in action.
TIL (Today I Learned) about the uncanny valley while talking to a couple of my friends about Tron 2. Apparently some of the computer animation in Tron 2 falls into the uncanny valley, aka the CGI humans are creepy looking.
The uncanny valley is a term used in robotics and computer animation when a robot is so humanlike people begin to judge it more like an inadequate human, and less like a impressively humanlike robot. It’s at this stage when the robot or CGI begins to look creepy or repulsive.
The reason we find almost, but not quite fully humanlike robots creepy is unknown. However, one theory is that at this stage of realism, our animal instincts kick in and ask, “what is wrong with this person!? Stay away from them! They might be diseased, dangerous, or at the minimum, incredibly socially awkward.” However, human caricatures, such as the humans in the movie the Incredibles, are obviously not real humans, but have humanlike qualities. This allows our imagination to fill the gaps with what qualities these characters would have, were they real.
That’s the gist of the uncanny valley. For a better synopsis, check out this short video on the subject and how it relates to video games.
We had a blast at the Ren Fest last weekend. While we were there I noticed one pesky problem. How does one free their hands with a bottle of mead in one hand and a glass in the other! It’s a common problem to be sure, because there’s a special knot called a bottle sling designed just for this purpose of carrying your bottle! Brilliant! 🙂
I also learned that a renaissance man’s doublet was not just a fancy shirt. It was also functional, or at least the original doublets were. Doublets were padded and worn under armor to cushion any receiving blows. Here’s a picture of a fencing doublet I took the Metropolitan Museum of Art back in 2009.
It’s been awhile since I wrote my last TIL (Today I Learned) post. A few things happened that have prevented me from posting:
- I couldn’t think up a good post one day.
- I worried these type of posts were not appropriate for my mostly how-to blog.
- I wasn’t sure these TIL posts provide much value to other people.
I’ve thought about these issues a bit in my spare brain cycles and have concluded: I’m WAY over thinking it. 🙂 I enjoy writing these posts so they shall continue. I have also decided to forgive myself for missing a day or 30. I’ll post when I feel like it! 😉
To make up for my short post hiatus, here a few things I’ve learned since my last post.
Sharlee and I have started taking dance lessons at Go Dance Austin. We’ve taken 1 private lesson so far and I finally learned how to 2-step correctly. I tried to find a video on 2-stepping to post here, but I couldn’t find a good one quickly. In any case we had a great time.
The Definition of Dearth
Somehow I’ve amassed a group of highly literate friends. Go me! I learn and forget new words from them nearly daily. The other day one of my friends sent me a text message with the word dearth in it. I looked it up. A dearth is a scarcity or lack of something.
The term gaslighting is one of the most interesting things I learned last week. If you try to trick someone into questioning their own memories, that is gaslighting. For example, you might invite a friend to your house to watch a movie and ask them to bring peanuts. A week later when they show up at your door with a bag of peanuts you say, “Are you trying to kill me? I’m allergic to peanuts! I told you bring anything BUT peanuts.” The victim will then question their own memory. I’m familiar with this behavior from movies, but I never knew there was a term for it. I learned this term killing time reading Reddit comments.
How to Properly Tamp Espresso
At Conjunctured we rent commercial grade coffee equipement from Casa Brasil. They come out occasionally to service the equipement, restock our beans, and answer any questions we have on how to use the equipment.
While watching the barista show our coworkers how to pull a shot, I discovered I’m not applying nearly enough pressure when I tamp my espresso coffee grounds. The recommended pressure is 40lbs! That’s a pretty solid push. Here’s a video I found that sums up what I learned about tamping the portafilter.
Summize is the 3rd party Twitter status search engine Twitter acquired. Being an old school Twitterer I’m use to typing in Summize.com in my browser’s address bar and having it redirect me to search.twitter.com. Plus it’s less to type. Now either the redirect is down temporarily, or Twitter has officially turned off the lights for the old brand name.
