That is the correct solution, a surrogate key.

There are no proper natural keys, natural keys are a bad solution to the real world problem of running and managing an application. The correct solution is to use a constraint to enforce the uniqueness of your supposedly "natural key&

1) Natural keys suck in the real world, artificial keys have come to dominate for a real reason that you either understand or suffer for ignoring. Natural keys are bad practice. 2) ORM's are good practice, they reduce massive amounts o

Never heard of anything like that, interesting. Sounds like some sort of synesthesia.

I have Aphantasia, nice to see people suddenly becoming aware of this. I'm hoping to see a lot more research in this area in the next few years, but anecdotally I'll say spacial cognition and visual memory are different things, I

Seems to me you simply fail to grasp the nature of science. You think science doesn't question it's assumptions and biases, you don't understand science. Science is a process for validating the validity of ideas, any ideas

Because science; believe it or not, scientists aren't that stupid, they've thought of all of that and tested for it to ensure their conclusions are correct. Your two seconds of thought on the subject don't come close to how m

Besides severance, there's unemployment which you can't claim if you quit.

> Maybe I cannot express this clear enough but the advantage natural evolution has over artificial evolution is the huge number of "experiments" - meaning it had time enough to do a lot of small changes until something worked.

Try reading more carefully, I said it was a partisan rant, and it was. I don't have to know your political leanings to know what you said was clearly a partisan rant. Talking to people who behave like racists, doesn't make them no

You're welcome to think otherwise, you're wrong, but I really don't care; I've seen the numbers, racism was the major factor in the election, it's not a matter of opinion, it's a fact. Ignore facts if you if li

Not compared to anyone, you don't need to compare to someone to make a statement that outside of tech, Zuck isn't that well known. It would surprise me to see millennials vote in swarms at all, that fact that young people generall

I think you drastically overestimate his name recognition; he's famous in the tech bubble, outside of that few would know his name. Everyone knows facebook, that doesn't translate to everyone knows Zuck. Beyond that, he's o

If any of your queries are locking tables find a better database; what a senior would do is look at the query log and say hey, you've got an N+1 cascade load issue causing this to be so slow, optimize the query to prefetch the sub data

If there were no tangible technical benefit ORM's wouldn't be popular. The debate rages on because ORM haters like Climate Change deniers, rarely understand that which they critique. The debate exists because one side is ignoran

That doesn't solve the ORM problem at all. Using a non relational database in no way solves the relational object impedance mismatch; it's frankly unrelated.

No, I'm defending the Chinese room thought experiment. It's cheating to look at the implementation and then claim it isn't AI; you can't look at the human implementation which could very well also be based on simple math

by gnaritas 10y ago
You're conflating human level intelligence with artificial intelligence for one, AI doesn't have to be human level to be AI. Secondly "statistical smoke and mirrors" is the Chinese room fallacy; it doesn't matter w

The timeless problem of AI, anything that starts out AI ends up being rebranded as not AI once it's understood. It's the no true Scotsman fallacy. Machine learning is AI, it's just not human level AI.

Which is what I was referring to by some practical output; however it's possible and common to acquire knowledge without there being immediate things to do with it. Certainly the knowledge is progress, but you called it the most signif
