Look at how American children live! I filmed this on my way home from New York City after attending the World Falun Dafa Day parade a few days ago. I happened to get stuck behind a school bus, which kept stopping and delayed me quite a bit — but it also gave me a chance to closely observe the happy lives of these children. As you can see, the school bus drops each child off right at their home. Sometimes two houses are only five or ten meters apart, yet the bus still stops separately for each family. It doesn’t try to save time by dropping the children somewhere in between and making them walk home on their own. Around the 10-second mark in the video, you can see a small child get off the bus and cross the street to go home. That’s why in the United States, whenever a school bus stops, not only must all the cars behind it stop, but even the cars coming from the opposite direction must stop as well — all to ensure children can cross the road safely. I filmed both of these clips from inside my car. I was quite amazed that day, but I hadn’t had time to share them until now. Today I finally wanted to show everyone. This is what a society built for people looks like! And compare American children's lives with those of Chinese children! A follower of my Chinese language account 曾錚 says that a lot of Chinese middle and high-school students are just like prisoners, and their parents are only allowed to visit them at school once a month!

The moisture question always comes up when I post pics of my indoor pools on my new builds. Step by step below on how I control it. We create a room where moisture can’t escape into other areas of the home while also having a mechanical system in place to pull the moisture out of the air so mildew/mold don’t ever develop in the pool room itself. In the STR space, investors are trying to stand out. Pools rent. Indoor pools rent even better. You can swim in the winter or summer. 1) Pool is always built on lowest floor inside (generally basement structure) 2) Concrete block wall for basement with very little wood frame 3) Densglass (kind of like a moisture resistant drywall) attached to concrete block 4) Special stucco just like you see on exterior of homes sprayed onto Densglass. The stucco is dyed to color of my choice. 5) Industrial grade dehumidifier (I use Santa Fe or Watchdog Brand). The humidity pulled from air is pumped back into the pool system near the mechanical room or outside. 6) Mini split for the pool room. Main floor HVAC covers the sleeping rooms, bathroom of basement and is always separated from pool room. You don’t want chlorinated air running through a main HVAC system. I look at having to replace the minisplit & dehumidifier about every 4 to 5 yrs because of the chlorinated air that goes through them. 7) Exhaust Fan leading to exterior which also pulls humid air out of the room as a supplemental support for the dehumidifier. When overhead lights are turned on, we have it so the exhaust fan kicks on as well. That’s it. We create a “bubble”, where no moisture gets into the other areas of home and the humid air gets pulled from the pool room.

Softmax vs Sigmoid ✍️ Interact 👉 = Softmax = Softmax is how deep networks turn raw scores into a probability distribution — the final layer of every classifier, and the core of every attention head in a transformer. To see what it does, picture five boba tea shops on the same block, all competing for your dollar. Five candidates: a, b, c, d, e — different chains, different brewing styles, different pearls. A boba reviewer hands you a 𝘤𝘩𝘦𝘸𝘪𝘯𝘦𝘴𝘴 𝘴𝘤𝘰𝘳𝘦 for each — higher means perfectly chewy "QQ" pearls with the right bite (ask a Taiwanese friend to find out what QQ means). Negative scores are real: mushy bobas, overcooked pearls, a batch left sitting too long. How do you turn five chewiness scores into an allocation that adds to a whole dollar? You could spend everything at the chewiest shop, but that ignores how good the runners-up are. Softmax is the smooth alternative. Read the diagram left to right. First, raise each score to e^{x} — this does two things: it turns negative chewiness into small positives, and it stretches the gaps between scores exponentially. Then sum all five into a single total Z. Finally, divide each e^{x} by Z to get a probability. The five probabilities add up to one, so you can read them as percentages of your dollar. The chewiest shop gets the biggest slice — but never the whole dollar. That's the point of softmax: it ranks confidently while still leaving room for the others. = Sigmoid = Sigmoid squashes any real number into a probability between 0 and 1 — the classic activation for binary classification, and still the gating function inside LSTMs and GRUs. Same boba block as the previous Softmax example, narrowed to just two contenders — a hot new shop `a` with chewiness score x, and your usual go-to `b` whose score is pinned at zero (the neutral baseline you've come to expect). Sigmoid is just softmax with two players, one of them pinned to zero. Read the diagram left to right. First, raise each score to e^{x} — for the usual shop `b` whose score is zero, this is just e^0 = 1 (the constant baseline). Then sum the two into a total Z. Finally, divide each e^{x} by Z to get a probability. The two probabilities add up to one — the new shop wins more of your dollar when its pearls get chewier, and your usual keeps the rest. That's the point of sigmoid: it turns a single chewiness score into a clean 0-to-1 chance you'll try the new place over your usual. --- AI Math, Algorithms, Architectures by hand ✍️ Subscribe to my 60K+ reader newsletter 👉
