One thing, off topic kinda, that I always wonder when I see mention of said computer.

Why people don’t use the Unicode symbol for Roman numeral two?

Apple Ⅱ+

lejoko · 3 months ago

Because Apple itself wrote it with square brackets.

Define "better language". The duck typed languages all suffer the same problem.

Even in Go we had a stupid problem where default json deserializer creates floats (when deserialized into any) and the number was high enough int64 where it lost precision.

I mean, we can go at it all night long what pitfalls await in what language. Perhaps Rust is safest with its own pitfalls where you just can't do it safely (looking at you BST and use of Arc).

Programming is full of such traps and only inexperienced engineers in a language would make such a mistake. This includes engineers with 20+ years of 1 year experience.

“only inexperienced engineers in a language would make such a mistake” — famous last words…

I read that as openTDD, and the comments about it being a game had me confused for a bit.

lejoko · 2 years ago

Same here. I wondered how TDD could be more open than it is already...

Funny, I did pretty much the same journey when I was young. As I grew older, I became disenchanted and eventually journeyed all the way back.

There are questions about conscience, the origin of the universe, the ultimate nature of reality, etc. that we haven't answered yet and perhaps never will. We have theories and we have models. We don't know which theories are correct yet and, if we eventually find a model that seems to work, we might not even be sure if it reflects reality or simply predicts it (like Newton's equations).

Furthermore, not all questions can be answered in this way. Every ethics system is grounded on metaphysics in one way or another: on concepts which are completely human-made, culturally-dependent, non-observable. Even the most Darwinian doctrines do this: genes don't actually "want" to be preserved and passed on, any more than rocks "want" to fall. Religions are simply more explicit about this than other belief systems.

Finally, it certainly doesn't help Dawkins and his followers that, despite claiming to be on the side of reason and truth, systematically let their judgements be influenced by their prejudices and preconceived notions. A more informed and grounded view of history would understand that a notion of the transcendent and the divine was the foundation for much of the progress of humanity.

So true. In the end, any truth is anchored in a beliefs system and you have to chose yours (or ignore that you've chosen one). Better chose one that helps you live a good and happy life...

So you didn't look any of these terms up? Would love an explanation of

* Kantian Wholes

* Catalytic Closure

* Constraint Closure

* Spatial Closure

* a first-order phase transition to molecular reproduction

* phylogeny of metabolisms

* template replication

Thanks

Read the article ! As it says : "We explain these concepts below."

If I invest my life savings into founding a startup and it fails, I lose my life savings. The engineer I hired to help build the company loses nothing.

lejoko · 2 years ago

If I invest pocket money (the same amount as you, or even more) into founding a startup with you and it fails, I lose pocket money. The engineer we hired together to help build the company loses his job and may find himself with serious problems because of that. Risk is in the eye of the beholder...

You're only proving my point about the value of being able to take on risk.

lejoko · 2 years ago

I don't see how. You said that engineers can take risks if they want. I say that: 1. a lot can't take any risk at all, even if they'd be willing to, since they have no money. 2. the level of the risk you take depends enormously on your initial wealth. Wealthy founders take a lot less risk than founders who invest their life savings. And when you get to the other side of the investment, when you win, the money you earn does not depend at all on the level of risk you took. But when you lose, it totally depends on it. the risk is not the same for everybody.

marknutter · 2 years ago

People often forget to factor in the value of risk. The reason engineers who join startups rather than found them make a fraction of what the founders make is because they didn't take on the initial risk of starting the company, which they are of course free to do anytime they like by starting their own company.

lejoko · 2 years ago

There is usually another reason (and I share it) : they don't have enough money to start their own company without it being too big a risk. It is an order of magnitude easier to take risks when you already have enough money so that your family is not at stake...

Perry G Mehrling, Economics of Money and Banking. https://www.coursera.org/learn/money-banking

He helped me understand what money really is. He explains pretty complex things that most people have a hard time understanding, in a very simple way. I got the recommandation from another similar thread here on Hacker News.

Obligatory "elixir+phoenix is supposed to inherit ruby on rails" remark

lejoko · 3 years ago

Rails + Phoenix dev here who loves both. Elixir is far from having the conciseness of Ruby and Phoenix is super far from having the tooling of Rails (and Rails from having the tooling of Beam and OTP). From my point of view they are two very different beasts, each one being great in its own domain. The similarities are mostly syntactic and superficial.
