When a startup claims it has “AI” or “ML” and then you take a look at the actual tech
Or as @elonmusk would say:

“I discourage the use of machine learning because it’s very difficult: 99.9% of the time, you do not need it.”

“AI”
AI, explained
Background on the American WWII unit that used these inflatable vehicles:

Was called “Ghost Army” (also, an amazing name for an AI company)

Anyways, you should follow @TrungTPhan for other revelations…like Nikola’s new Defense Department contract to build tanks:

PayPal’s bland logo redesign was inevitable

If you are the person that did the un-aligned letters for the previous eBay logo, please contact the research app team. We are huge fans of how un-aligned the “e” is with the “y”.Bearly.AI
This article offers up reasons for popularity of simple font logos (mostly Sans Serif):

— Easier to standardize ads across mediums
— Improves readability (especially on mobile)

Berkshire Hathaway board member Chris Davis once asked Charlie Munger why Costco didn’t drop the membership card.

Let anyone shop and raise prices by 2% (still great value), thus making up for lost membership fees (and more).

Munger said the card is important filter:

▫️“Think about who you’re keeping out [with a membership card]. Think about the cohort that won’t give you their license and their ID and get their picture taken.

Or they aren’t organized enough to do it, or they can’t do the math to realize [the value]…that cohort will have a 100% of your shoplifters and a 100% of your thieves. Now, it’ll also have most of your small tickets.

And that cohort relative to the US population will probably be shrinking as a % of GDP relative to the people that can do the math [on Costco’s value].”▫️

I have a membership but have been guffing on the math for a few years tbh. They keep telling me to upgrade from Gold to Business but I’m too lazy (even if the 2-3% Cash Back on Business pays back after a few trips).

This is a long way of saying Costco’s membership price hike effective today — its first in 7 years — is annoying but when I decide to do the math in a few months, it’ll be worth it.

Chris Davis’ remarks from this episode of The Knowledge Project: open.spotify.com/episode/6fJYHF…Image
Anyway, here is something I wrote about Costco’s $9B+ clothing business my affinity for Kirkland-branded socks and Puma gym shirts. readtrung.com/p/costcos-9b-c…
Two notes:

▫️Meant “Executive” (not “Business”) membership
▫️Chris Davis was doing a pure thought experiment. Costco membership obvi high margin (on~$5B a year) and accounts for majority of Costco profits. Retail margin is tiny on ~$230B of annual sales (Costco would need like another $150B+ from letting anyone shop to make up membership profits)Image

Explainer video on science of why the 400m sprint is considered the most painful track & field event.

And why “no person on the planet can run the 400m all out from start to finish".

The race pushes the way the body creates energy to the limit:

▫️0-50 meters: ATP-CP (energy system for very short and explosive movements; used up after 5-10 seconds)

▫️50-200 meters: Anaerobic glycolysis (burns glucose without oxygen, leading to lactic acid buildup and muscle fatigue)

▫️200-300 meters: Aerobic energy (uses oxygen to break down glucose, but cannot keep up with the demand)

▫️300-400 meters: Anaerobic energy reserves tapped while aerobic energy is too slow to fill the gaps (lactic acid buildup is going HAM)

Track athletes can pace for longer distances and shorter ones are just over quicker (obvs).

The Olympic record is a blazing 43:03, set by South African runner Wayde van Niekerk in 2016 (and 2024 Final race is tomorrow).

***

Full video from Outperform:
Usain Bolt ran the 400m early in career but then said training was “too hard”.

The 400m Hurdles is a world of pain too for similar reasons — Vox has a good vid on it:

Here is a great breakdown of Wayde van Niekerk’s record run:

The 400m is also tough because you don’t get the benefit of an absolute baller like Bottle Klaus keeping hydrated

The amount of work Hayao Miyazaki and Studio Ghibli team put into a film is mind-boggling.

Each typically has 60k-70k frames, all hand-drawn and painted with water color.

This 4-second clip (“The Wind Rises”) took one animator 15 months to do. Insane.
The docu “10 Years with Hayao Miyazaki” shows him talking to the animator (Eiji Yamamori) after its done.

It’s so good:

Miyazaki: “Good job.”
Yamamori: “It’s so short, though”
Miyazaki: “But it was worth it.”

The animator gets a second of joy (he’s pumped) but on to the next.
Miyazaki doesn’t use digital FX or computer graphics. He believes “that the tool of an animator is the pencil.”

On a related note, here’s something I wrote about another Japanese legend dedicated to the craft (Ichiro Suzuki) and the art of mastery: readtrung.com/p/jerry-seinfe…
