exceptions follow this flowchart:pre:Can I do something about this exception ? | -- Y-> What Can you do about this exception ? | | --> I can do something about it like maybe fix it or maybe send it to someone or w/e and that will be the end of it | | --> Handle the exception | | --> I can add some information about the state of things so maybe someone else can handle it | | --> Wrap in new exception with additional info and throw | -- N -> Throw

id be more worried about spring best practices. best practice is actually "very carefully".

spring is neither good nor evil but it can be used to great effect in either direction.

i worked on a project where literally every single class had to be instantiated via spring, even just pojos. not only that but the team lead wouldn't let you use any spring annotations, so you had to manually get a handle on the spring context to instantiate even the most simple beans.

java is neat. i'm neck deep in a big ole spring + hibernate project right now and life is easy don't ever write xml, read effective java, and break your spring config into multiple small @Configuration classes, combined in a single context ftw e: i get that hibernate is actually a really bad way to manage data but drat if it isnt easy more like dICK fucked around with this message at 03:10 on Apr 30, 2015 |

more like dICK posted:e: i get that hibernate is actually a really bad way to manage data but drat if it isnt easy hibernate owns gently caress the haters the key thing to remember is that hibernate doesn't have to own your schema. you CAN let hibernate own the schema, but it is entirely possible, practical, and pleasant to use hibernate with a schema the application does not control.

hibernate has a laundry list of gotchas and pitfalls and ime it's pretty easy for beginners to waste a lot of time dealing with pretty routine crap. i can't count the number of times i've seen beginners struggle with poo poo like the persistent/detached dichotomy or session management and that's just basic poo poo outside of things like hairy performance issue.

 the haskell man is goneedit: i guess i'm late to this funeral To the Yale College Community, It is our sad duty to inform you that Paul Hudak, professor of computer science and master of Saybrook College, died last night after a long battle with leukemia. With him were Cathy Van Dyke, associate master of Saybrook, and their family. Professor Hudaks life and work touched so many people, among them the students and faculty in the Department of Computer Science, the community of musicians who shared his love for jazz, the high-school lacrosse athletes he coached, and the students, staff, and fellows of Saybrook College. A memorial service is planned for Sunday, May 3, at 1:30 p.m., in Battell Chapel, giving the community a chance to come together, honor Professor Hudak, and celebrate his life. Friends may call on the family on Saturday, May 2, from 2:00 p.m. to 6:00 p.m., at Sisk Brothers Funeral Home, 3105 Whitney Avenue in Hamden. Sincerely, Peter Salovey President and Chris Argyris Professor of Psychology Jonathan Holloway Dean of Yale College; Edmund S. Morgan Professor of African American Studies, History, and American Studies

eschaton posted:I read some of that Tetris code and it didn't seem significantly different from Haskell. Elm's syntax is almost exactly like Haskell's. If you don't like Haskell's syntax you won't like Elm, but besides syntax many people's beefs with Haskell come from (a) people's liberal use of complex structures from category theory, and (b) lazy evaluation being really confusing to reason about. Elm addresses these two things by not having typeclasses and using eager evaluation. These are compromises of course, but the payoff is a vastly simpler language than Haskell, even with the syntactic similarities.
