Thanks! What about data structure shared by multiple goroutines? Say, an in-memory cache object? Or do we always have multiple goroutines talk to a dedicated goroutine for the shared value? Would the performance be okay for all use cases? A

I remember HN had a repeating popular post on the the most important data structures. They are all the basic ones that a first-year college student can learn. The youngest one was skiplist, which was invented in 1990. When I was a student,

It looks we are in this interesting cycle: millions of engineers contribute to open-source on github. The best of our minds use the code to develop powerful models to replace exactly these engineers. In fact, the more code a group contribut

A funny thing is the US could easily sanction any country in the 90s because it controlled so much manufacturing. Nowadays we can’t even sanction Houthis since they can get everything from China. Judging by the port situation, soon China ca

I really hope that capitalism works this time: we bring back our key manufacturing. One may argue that toys are not key manufacturing, but I think that argument misses the point. The point is, a truly industrialized country can produce anyt

A trajectory question: do we still have the debate that whether open-source software takes away SDE jobs or makes the pie grow bigger to create more jobs? The booming OS community in the past seem have created multiple billion-dollar market

I have a more charitable view on the "AI-first" movement. When you're a CEO, the last thing you want is for your company to miss a major tech shift. We've seen this story play out repeatedly - companies that didn't

Duolinguo tries to follow the input hypothesis. For instance, it barely teaches any grammar but simply asks its users to translate sentences. Unfortunately that's very ineffective. Compared to reading or watching live conversations, th

The choice between Made in Asia and Made in the USA can be more complicated. For instance, I will acknowledge that 85% of price difference is a lot, but then I'd rather own less stuff: less clothing, less food, certainly no goodie bags
