Lots of fun counter examples to this. Complex numbers were introduced in the 1600s with no practical application for almost 300 years until they were used in electromagnetism and quantum mechanics.

i notice a huge difference between working on large systems with lots of microservices and building small apps or tools for myself. The large system work is what you describe, but small apps or tools I resonate with the automate coding crow

it's used extensively in java and it would be my first choice when starting a java project. I don't think I'd use it in Go though.

Ya except people with innate talent are frequently lazy and take their talent for granted. You can often outwork these people and get better than them

I kind of agree with you. On the one hang OP is logically correct, on the other it's very sad and a form of a tragedy of the commons. If everyone gave candid feedback we'd all be better off.

Even when it is the case you can logically come to a resolution but if you don't emotional feel it, the problem/conflict is not solved and will come up again. In my experience this manifests in non obvious ways that are far remove

I think this blind spot exists because the pure engineering/logic mindset is such a massive superpower in so many elements of life, people fail to consider that it might not always be the right way to think about the world. One obvious

A lot of people should be mad at Marc Tessier-Lavigne, not just HN folks. He lied for personal gain at the expense of scientific progress and millions of patients who suffer

The controversy over the amyloid hypothesis comes from a Stanford professor faking data[1] and setting the field back decades. The amount of harm this individual caused is hard to overstate. He is also still employed by Stanford. [1] https

in poker AI solvers tell you what the optimal play is and it's your job to reverse engineer the principles behind it. It cuts a lot of the guess work out but there's still plenty of hard work left in understanding the why and ulti

For comparison if you run your own hardware and do a memcached KV lookup with a different server on the same rack, p99 times are slightly under 1ms. Given the guarantees of cosmosdb ~10ms isn't that bad for a p100

I had a lightbulb moment recently where I had a recruiter ask me if I had any experience building recommendation systems. While I don't use that word on my resume, my resume is full of technologies and projects that point toward recomm

Imagine a scenario where option B does 10x better than option A during the morning hours but -2x worse the rest of the day. If you start the multi armed bandit in the morning it could converge to option B quickly and dominate the rest of th

git bisect is an absolute power feature everybody should be aware of. I use it maybe once or twice a year at most but it's the difference between fixing a bug in an hour vs spending days or weeks spinning your wheels

Figure out the core technologies they use and become an expert at them. Read the documentation of those technologies like a book. Is kafka at the heart of the stack? Learn everything related to kafka and setup a small dummy instance to play

It would obviously be crazy to roll your own numpy or lightgbm. But there's plenty of bloat in the library space where the cost of integration and upkeep is far more expensive than a simpler implementation of your own

It's crazy because the JDs will be so extremely specific to a niche skillset and I still won't get a reply.

If I'm not having fun learning something I can't stick with it. Efficiency without tenacity/grit is useless. It's kind of a tautology that "more efficient is better", but I agree it's pointless without fun

How do you personalize to the specific signals of the product, do they ingest into your infrastructure? What happens if a customer discovers a bug in a feature they're ingesting, how do they have control of retrains/pinning model
