her smile stays the same, why is this making her less convincing?

Ohhh she is a researcher.  she has stuff to promote.

uh oh, this thing is about growth mindset.  this idea smells like group think to me.  learning about the brain and how it grows when we face challenges we can change our mind about failure being a permanent thing.   i think i've heard and read these things before, but in the context of language learning, and things were so technoutopian.

well here it is on youtube:

Film: Trapped

https://en.wikipedia.org/wiki/Trapped_(1949_film)
the lack of a surprise ending got me.  the cino was great.  i guess this was a b movie, perhaps shadow produced with mob money. the fight scenes were so realistic it made me wonder if all the actors weren't boxers.  oh yeah, there was a scene with a bus ride, and the bus looked awesome.  i hope i don't die pointlessly like some of the characters in this movie do

Film: Terminator

I watched this movie after seeing a music version of it.

However, I think I've seen the director's cut, but there were a lot of things in the musical that were mocking parts of the film I could not remember.  So, now I've watched the theatrical version on youtube.

I do remember the scene where arnold cuts out his eye, so i have definitely seen a version of this.  I wonder if i was eating while i was watching it or what.

there are a lot of hacky lines, "follow me if you want to live."  i think the sex scene maybe has one scene too many, but it also shows how passionate they are.  this might be more important because the two characters don't seem to be developing a romantic relationship before this scene.  the couldn't do it with lines, they did it with naked bodies.

after i write this i want to read what, if anything, roger ebert wrote about this.

Film: Rock and Rule

https://en.wikipedia.org/wiki/Rock_%26_Rule

i saw this on 35 mm at weird wednesdays at alamo.  some guys tried to tell me too much about the movie before it started.  they had mics and were friends.  i wanted to yell at them and tell them to kiss. they were being overly earnest.

about the film.  wow, the guys weren't wrong.  the animation was amazing.  hand drawn holographs and the detail everywhere. the TV aesthetic parts were doubly animated.  they said 300 animators were working on this project and it almost bankrupted the studio.  i thought that was blah blah blah but after seeing it i think that was something I would have wondered about.

oh yeah and the music has never been released.  it was all pretty good, but it was kinda weird that the best song was in the first 5 minutes. 

the bad guy was pretty darn evil, but i dont really know if it mattered.  there were lighthearted bits here and there.  sometimes the crowd laughed, like when someone's butt showed through a pipe.  i think i was pretty in sync with the crowd for the most part, which is rare for me.  usually i laugh alone.

the story showed real thought and the message was timeless, a real masterpiece.  like the guys with mics that didn't kiss said, it is better than heavy metal.

I have no idea what they are doing in this video.  Chopping trees from the top? They are very skilled and athletic, but I don't know how much this resembles actual tree chopping.  My guess is not very closely.  Also, the angle makes it a bit hard to see what all of the choppers (?) are doing.  The crowd seems to cheer randomly and gives me a bit of fomo, I rewound a couple of times to see if I had missed anything but didn't see what make them aw and ooh.  Still, this video was entertaining.

YT: This old house: bathroom sink and basement wall

https://www.youtube.com/watch?v=4yCBQ2WRbyI

saw some cool bell clips in the first part where they install a second sink.  also the copper supply tubing that is part of the sink is interesting.  using putty underneath the spout is something i dont usually see.  maybe these days there's a washer built in? I wonder

the second part with the basement hole.. neato.  the mortar mixing looks great.  doing it by hand is tough, a drill makes it easy to mix.  also using a cold chisel to get chisel out a hole thats perpendicular to the wall so the mortar sticks.  that makes sense to me.

(edit: it does say in the title of the video that this is from 2011.  methods may have changed since then)

YT: Tech Lead loses money

https://www.youtube.com/watch?v=5IcvRe8bQhU

YT: Five problem solving methods

https://www.youtube.com/watch?v=GBuHSRDGZBY

This video from CS Dojo shows some real steps he took to solve problems.  It was really helpful to see how these could strategies could be applied to a real problem.

Here are the steps:

Tip #1: Come up with a brute-force solution - 1:23
Tip #2: Think of a simpler version of the problem - 2:34
Tip #3: Think with simpler examples -> try noticing a pattern - 5:54
Tip #4: Use some visualization - 10:10
Tip #5: Test your solution on a few examples - 15:09

#3 and #4 were almost the same, he used pretty much the same matrix for both.  The matrix he made turned out to be the visualization. But, there was a bit more sorting done so it *was* actually a bit better, even though the concept was essentially the same.

Anyway, CS Dojo really nailed this one.

YT: Real time anti aliasing

https://www.youtube.com/watch?v=fQlQQSsC47g

real time antialiasing looks great.

as predictions go, these are too sweeping to be realistic, i'm pretty sure there will be big changes in game making, but i think this guys take is mostly meant to generate more engagement on his channel.

solid tips, it helps to have a second person to center the faucet.

This old house:

https://www.youtube.com/watch?v=RsqQC26uhqc

theyre changing a whole vanity here.  they use compression supply valves instead of soldering.   also the countertop is granite so they use special putty, normal plumber's putty contains oil which will stain the granite.  intsall the sink before putting the countertop into the cabinet

https://www.youtube.com/watch?v=IbUXb4pQbPY

YT: What is Pytorch?

https://www.youtube.com/watch?v=nbJ-2G2GXL0

Siraj Raval explains what PyTorch is.  Torch was written in Lua and some people rewrote it in python as PyTorch.  Symbolic programing and imperative programming are important concepts to understand to understand what PyTorch is.  Somehow this is related to deep learning, which has something to do with neural networks.

Tensorflow - best documentation for machine learning. ok tensorflow is similar to pytorch.
Distributed cross validation
Dynamic Computation Graphing
Writing a whole program before running it.

Static graphs work well for fixed-size networks, but sometimes dynamic graphs are more useful when the input changes.  I'm not sure what kinds of changes would make the switch beneficial, but I hope to understand that soon.

autograd package, I guess this is a framework.

Sorry this one post is a mess.  There was just so much info and most of it was jargon.

YT: What is Docker?

https://www.youtube.com/watch?v=_dfLOzuIg2o
Docker is kinda like a virtual machine but there are significant differences.  But yeah, Docker helps people ensure compatibility across platforms.  It lowers costs because you don't have to spend as much effort to port whatever youre making.

YT: Huevos Rancheros

https://www.youtube.com/watch?v=IYhnyp-xKTs

The sauce looks fun to make and delicious to eat.  I'll have to get ahold of some of those peppers.



2 white onions 4 Roma tomatoes, cored 2 jalapenos 2 serrano peppers 6 garlic cloves (divided) 2 guajillo chiies finely chopped

 Slice the onion in half, but be sure to keep the root ends intact. Begin by preparing the vegetables: Core the tomatoes, slice the stems off the jalapeno and serrano peppers and remove the seeds, if desired to reduce the spiciness. Slice the onions in half, but keep the root intact. Fill a large saucepan about halfway with water. Add all the vegetables and 4 of the garlic cloves. Bring to a boil for about 10 minutes or until the tomatoes are tender, adding more water if needed. Remove the vegetables with a slotted spoon and let cool. Peel the outer skin of the tomatoes off and discard (soaking them in cold water beforehand, will release the skin easier). Cut the stems off the jalapeno and serrano peppers, and remove the seeds, if desired. Remove the root of the onions. Add all the vegetables, along with the remaining 2 garlic cloves to a blender, and diced guajillo peppers and Salt and pepper, to taste. Blend until smooth. Pour the contents in a saucepan to a boil. Reduce the heat to a simmer, cover and continue to cook for 10 minutes, stirring occasionally.

YT: CS Dojo Algorithms and Data Structures

This is a big series:



A few things I learned about:

Hash tables
Arrays
Memory Management

at first there were some interesting examples, then it switched into what i call "black box" mode, where there are random numbers and boxes, with numbers move in and out of boxes.  no story or reasoning.  at least Mr CS Dojo has crisp pronunciation so I can watch the videos at 2x speed.  They are coherent, too.  I am rarely distracted because I don't get confused.  In other words he does a good job.
