The index of only top 4 stocks outperforms any larger index: sovereignoptimist.com/i/2117…
For the last two months, I’ve been rewriting Deltabadger in Rust.
My conclusion so far:
The era of interpreted languages on the backend is over.
My new app is 10x faster and uses 7x less memory on the server. Nothing justifies giving that up.
It’s true that the more concentrated the portfolio, the higher the volatility - but volatility matters only in the short term. Here is what many forget:
Growth is volatility.
In the long term, the better-performing basket will usually be the more volatile one.
I remember learning how shares work and being excited about attending shareholder meetings and getting to vote. In reality, most modern investors never experience any of this.
ETFs, RWAs, CFDs, fractional shares - ownership is outsourced in many ways. Even with regular shares, voting rights are often limited, and most investors never even think about using them.
Have you ever participate in a shareholder meeting?
I forgot that writing in compiled languages needs a strong multicore machine:
- Ruby: 10 agents doing different things
- Rust: 1 agent hogging all resources for 25min to run the full test suite
The M5 Ultra makes sense after all.
In 2016, I wanted to build a website that compares different objects in the Solar System. It was always a bit too much work for a project that couldn’t be monetized. Yesterday, I oneshotted it with a ridiculously small prompt (below).
solar.janklosowski.com/#eart…
The prompt:
"Build comparison tool for objects in the solar system. It should behave similarly to tools comparing phones etc. but there is no winner
- two columns for different metrics
- beautiful 3d realistic representation of each object in relative scale so they're always both in the same scale rotating slowly
- cover sun, planets, all moons and the most famous asteroids
- dark color scheme, beautiful minimalistic design"
At this point, Trump’s bromance with Putin is just bizarre. Why does he keep doing him all these generous favors while Russia helps Iran? What’s going on?
If $TSLA and $SPCX merge, SpaceX holders will likely do better: Elon owns only ~15% of Tesla, so he’s incentivised to favour his bigger stake.
I like how people suddenly have a problem with the Roadster being impractical: “What’s the use case?”
Isn’t the whole idea of a performance car that it’s basically a toy? What’s the use case for any two-seater? It’s not made for regular roads and speed limits anyway.
A lot of excessive token usage comes from really dumb things unsupervised agents do:
Unoptimized Rust tests run for over 100min while the agent wakes up every 10 minutes and loads an 800k-token context each time, etc.
This kind of stuff burns through your limit in a few hours.
S&P 500 is a geriatric relic. If you look for a simple replacement ready for the next decade, it's $QTOP - the top 30 Nasdaq companies that generate most of the market growth. sovereignoptimist.com/p/the-…
What most critics miss is that the software cycle has died.
Yes, people still use legacy software and will for years to come, but good luck promoting a new app.
In the past, the first users were “early adopters,” but that avatar is exactly the person now playing with AI.
"It may be true that AI is no different from previous breakthroughs, but that doesn’t mean that breaking points don’t exist at all."
