coffeetable posted:theoryspergin': only true on balanced trees. trees in general it can be O(n) b/c their height can be O(n) True. Most key/value data structures in functional programming are based on trees of different branching factors (because that's often pretty much the best you can do in many cases without breaking immutability) and will use balanced trees because otherwise the performance will turn to poo poo. I tend to forget that non-balanced trees are still a thing that is useful sometimes  We butthurt functional programmers will have different ways to think about things so we think we're super efficient though, so we get excited about amortized performances in pure data structures instead.

i dont really understand wtf you are talking about with strongly typed results from your ORM. your ORM should be using a schema to define types, and your database is already typed. what additional typing are you asking about?

that's not an orm, that's a result set from the server. and each field in that result object does have a type (kinda - it's stored with the column definition but internally i think it's stored as an object), but you have to know in advance what the type of each field is supposed to be so you can access it right. well-written c# demands strong typing w/ real classes and farting around with converting between unknown formats is poor practice at best and unstable at worst

Jonny 290 posted:java: java classes are objc interfaces. java interfaces are objc protocols. objc static means a million things because of its C heritage, and none of those meanings are the same as java's static. java will complain if you do stuff with null (nil). objc is more laid back and just lets the nil propagate to somewhere a user can see it.

It's like Mybatis but has more dependencies so you know it's doing something cool with them.

if your data is important, don't use an orm. if your data is sort of important, ok use an orm I guess and then spend 1000x the time you "saved" by using an orm on your reporting. if you data isn't important it doesn't matter what you use.

I use mybatis.net but u could use entity framework if you wanted. I didn't like it myself. tbh I don't know that much about other db frameworks. you can also make ur own on top of ado.net if you hate yourself.

Bloody posted:shagster im using c# and aspmvc4whatever what should i do oh ffs. in this case use ef 5, implement a generic repository using rest verbs, get a unit if work to sync your repositories and loving go nuts. go code first or at least use the POCO reverse generator if you already have a data schema and live in harmony with your orm that can still be reported from because you were smart enough to model your entities into bcnf. enjoy

the best thing to do is use EF like a statement mapper cause you don't have to deal with too much DB schema poo poo in ur code but you still get strongly typed result sets. it owns

i got spring jpa set up. IDEA wrote most of the code for me, i basically just told the ide that there was a postrgess db at localhost:5432 and it took it from there. then i started looking at some of the spring aop stuff for transactions and logging and oh my god this rabbit hole is terrifying there is xml and annotations everywhere
