Welcome to Short Writings. This is a post for less formal and shorter comments, related to anything I’m focusing on. You can also see the plan for this website here.

It’s Friday again, two weeks after the Monza Grand Prix. I can’t understand why McLaren asked Oscar to change position. If it’s the team’s fault on the pit lane, it’s Lando’s group’s issue. Oscar shouldn’t pay for the mistake by the other crew. Making Oscar lose his second place is a great breach of sportsman-like spirit.

Can I see a Ferrari driver win an F1 WDC before I’m 30? 😭

I’ve long been thinking about what will happen if everyone is using the same 80% reliable model for quantitative stock trading. My friend gave a possible answer that this is a paradox, as the model is impossible to reach 80% reliability if everyone is using the same model.
One possible reason for the model’s failure is that the market may have limited liquidity, resulting in minimal bidding from traders. If the price drops and the model decides to sell, the market will receive massive asks and few bids, resulting in few transactions. In this background, the right decision is impossible to make, so the 80% reliability is impossible to achieve.

Just be surprised that so many people get frustrated by the recent change in Delta Force, the video game. Delta Force imposed a 5 people limitation on players available at one extraction point, which means players from two different teams of 3 can’t exit together, leading to more fights.
In short, if you don’t like a game, just quit it. If there are too many players quitting, the official will make changes to make this game attractive.

This is the first post on Random Short Writings in 2026, so I’m supposed to say happy new year, but I’m not going to do so.
30 minutes ago I sold all my gold holdings. I know gold price will keep growing, but I made my decision based on my conscience. Last night Iran carried out multiple missile attacks against Israel and other middle east countries. The gold priced increased for the global risk. I feel that my money is sweated by blood, so I sold them all, even though I know it’s an irrational decision.
May the war ends, may the peace be with us.

Believe it or not, I sold all my gold at the highest price on 2rd March. The gold spot price collapsed almost immediately after I sold my holdings.😅 Sometimes wise decisions are made unconsciously.
