Ah yes, thousands of people benefiting from cheap and effective drugs that can’t be patented because they naturally occur. Of course it doesn’t work. /sarcasm

The medical field has a terrible problem in terms of literature reproducibility and ethics. The beta blocker scandal is a great example.

Agreed. I've run into so many issues with documentation and sane defaults, and the Vercel team response is to always gaslight you into thinking you've done something wrong.

The truth is, its just poorly designed software.

Where it shines is batteries included for getting started. They realized if you have low activation energy requirements, you will win a critical mass of people who put up with your crap. A good metaphor for devtools overall.

Ironically I think these types of exercises are part of the problem at major software companies; terrible efficiency and over hiring.

Because you need to “brag” to get rewarded, everyone ambitious has a list. And each list is nearly impossible for middle managers to evaluate. Someone may solve a hardcore engineering problem that has no business impact. Another person might redo some docs. Someone may create a design system version. Lots of token achievements, but not real work.

Real work should stand on its own and competent managers should be able to identify it. Mediocre managers rely on lists, so then people start showing up to work and making lists.

This doesn't make sense.

1. The top 3% seed-stage investors are killing it. 2. This seems to be engineered for the bottom 90% of investors. To squeeze out some yield. But venture capital is ruled by the power law. 3. Forcing seed stage tech founders to think about this complexity makes no sense.

I've worked at 3 startups, founded 2, and worked at 1 bigco.

2/3 startups had excellent returns in the form of equity. Life changing over time. Startups: 66% hit rate.

Bigco was mentally draining and sucked. Bigco: 0% hit rate.

Starting the first company was a failure, but the second one seems to be doing pretty well. 50% hit rate.

Love the age + free filters. First I'd heard of Swift Playgrounds! I wonder how they decided which ones to include. Also, first time I've seen learning resources broken down by apps, games, videos, etc. To be honest, it makes a lot of sense.

As PG said, take on as much technical debt as possible: it’s literally leverage.

Now sometimes “clean” code is the worst of both worlds. It wastes time and isn’t really clean.

Clarifications (this comment perpetuates some common misconceptions):

- A single bitcoin "transaction" can actually have thousands of inputs and thousands of outputs. So energy "per transaction" or "transactions per second" is not analogous to a typical monetary transaction.

- Bitcoin does not compete with literal credit card transactions (although some use it like that today). I'd compare Bitcoin on-chain transactions with how nation-states settle their central-bank ledgers with gold. Gold is the best comparison to Bitcoin because trading in hard gold is "final". Credit card transactions happen on a higher level in the financial stack. As does cash. As do bank transfers. All of these bubble down into interbank transfers that eventually settle on the base layer of central banks. So compared to shipping and securing gold, Bitcoin is quite cheap!

Federation is actually quite centralized and explicitly so. DNS resolution is “federated”.

Proof of work is the opposite end of the spectrum; maximally decentralized yet slow.

The worst of all worlds is proof of stake / stake-based consensus. It’s expensive yet super fragile.

- Adding to the above point; if Bitcoin succeeds in beind "adopted", it would not mean we no longer use credit cards. Credit cards would just port their underlying mechanism on top of Bitcoin instead of fiat moneys.

Some of the smartest people I've ever known from college became professional stock market investors and traders. Not a single one of them has significantly outperformed the market.

I think of stock market investing as a white collar gig economy job. Both depend on some central entity, which makes a killing (brokerages in this case), and have extremely low barriers to entry.

If you have super high throughput, it would be worth temporarily (and very securely) caching transaction parameters to handle downtime.
