oh, austin 🤠
Ten things Paul Millerd likes about Austin. “Many people claim to have moved here because of the lack of state taxes. I think people are lying. If that was the case they would have moved to Dallas. This may be a bold claim but I think there is something unique and compelling happening in Austin right now and I think people would consider moving here even if the tax rate were higher than NYC.” | learn more
tech, startups, internet ⚡
On the market for programmers. “Programmers in the US are well-paid and companies report difficulty hiring programmers. At the same time, while it’s less reported, there are a lot of people who are good at programming but can’t get programming jobs.” | learn more
Reverse stock slips for collapsed SPACs. The NYSE requires listed companies to be worth at least $1 per share. To raise price per share, they reduce the number of shares. “But some didn’t even get that far and filed for bankruptcy, like, WOW that was fast.” | learn more
Unchecked AB testing destroys everything it touches. Derek Zumsteg discusses the oft-ignored downside of website testing. Once all the winning ideas are implemented, is the cumulative result actually better? | learn more

Circular time vs. linear time. This is a fascinating concept that I hadn’t heard of before. It begins with the idea that for farmers, time is circular, and curls back into itself, while for nomads and merchants time is linear as they journey through ever-changing circumstances. | learn more

Every digital health startup is a clinic now. “The best in the category are redesigning the experience from the ground up to take advantage of the new digital medium, vs. just working to recreate in-person health care experiences online.” | learn more
retail therapy 💸
The problem with Amazon sellers like MOFFBUZW. “Black-hat international sellers … hide behind shell businesses and fake names. if they get popped for writing fake reviews or selling a product that kills someone, they just show up next week under a new account.” | learn more
under the microscope 🔬
How ‘The Dress’ sparked a neuroscience breakthrough. Remember the white/gold/black/blue dress? “Thanks to years of research into photoreceptors in the retina and the neurons to which they connect, [neuroscientist Pascal Wallisch] thought he understood the roughly thirty steps in the chain of visual processing, but “all of that was blown wide open in February 2015 when the Dress surfaced on social media.” He felt like a biologist learning that doctors had just discovered a new organ in the body.” | learn more
Your memories are not always reliable. “We replicated the findings of the original study, with 35% of participants reporting a false memory for getting lost in a mall as a child (compared to 25% in the original study). However, using a novel self-report measure, just 14% of participants declared that they remembered the fake event occurring, with a further 52% stating that they believed the fake event had occurred. The replication supports the claim that it is possible to plant a false memory of a childhood event.” | learn more

Reputation in Web3: ships built on the great flood. “If anything, it seems like crypto has made the ‘old’ centralized social networks, especially Twitter, more central than ever.

Where else would advocates for new coins and tokens state their cases and share their memes?” | learn more
