for the sql interview guy a good one people forget about is the HAVING clause used with GROUP BY

i like CTEs but I doubt an interview would ask you about them and probably not even ask you a question where they would be useful

so bone up on your JOINs

i am capable of using having/group by, but i have never been able to retain the knowledge two minutes after it's done :saddowns:

can someone show a really stupid example of java lambda stuff because i've googled around for it before and it just sorta assumes you know a bit about them anyway. I actually asked some lovely comp sci ta's and they didn't know that java had lambda expressions but i just wanna car extends vehicle bad programmer example of how they are used and why they are useful since I am p sure my school isn't actually gonna tell me. they seem like they are only good for finding instances of an object in some collection that have properties that fit a specific criteria but it seems like it should probably be able to do a lot more if it was important enough to bring over from other languages. I've been lookin at this

lambdas are really, really useful for collections

code:

List<Student> students = persons.stream()
        .filter(p -> p.getAge() > 18)
        .map(Student::new)
        .collect(Collectors.toCollection(ArrayList::new));

i would argue that lambdas were added to the language primarily to enable the improved collections libraries. they were certainly developed together.

the collections stuff is one of the biggest improvements in the std api pretty much since generics imo. 7 and 8 were good releases.

I think to really appreciate lamdas you have to have spent time in callback anon inner object hell and see code like this everywhere

code:

public void setUpTheNozzle(final someBar) {
    myNozzle.addClickHandler(new ClickEventHandler<ReturnType>() {
        
        @Override
        public ReturnType clickEvent(ClickEvent c) {
            doSomeRetardedShitWIth(someBar);
        }
    });
}

there are code bases out there where that pattern is utterly pervasive. the new date and time stuff looks pretty good too. too bad none of my clients are going to switch to java 8 any time soon.

Turns out if you open something with a .msg extension that is not a .msg because you didn't bother to check the downloaded file type and just assumed it was right outlook will barf a file locked error

so i've been using a lot of middleware stuff to make a product for a client. usually small SaaS companies are really awesome and will send you out a person email asking to chat for a few minutes.

well one I signed up for yesterday sent me a similar email but said like "Dear PleasureKevin of Nintendo (originally ClientAppName)"

i was like um sure I can chat but why do you say "originally ClientAppName"?

i noticed they checked out my LinkedIn page where i guess it still says I work at Nintendo.

so they email back and say they've also invited two executives from Nintendo to our meeting.

what the hell that kinda feels like an invasion of privacy.

i would argue that lambdas were added to the language primarily to enable the improved collections libraries. they were certainly developed together.

Elaborating on this, the vast majority of for loops in application level programming could be beneficially replaced by functions that take lambdas as parameters.

Benefits over for loops:

more succinct
reveals intent and is more readable
modular
less error-prone

Imagine the equivalent for loop(s) required for the above example. Now imagine more complicated examples with grouping, joins, counting, and whatever arbitrary collection processing.

Using lambdas w/ collections is analogous to sticking pipes together that feed into each other. This is a much better situation than wracking your brain over what i j and k mean right now in a deeply nested for loop.

you have to explicitly request laziness by converting a collection to a stream, which is very easy

most of the operations for collections are also available on streams. it's pretty darn easy. oracle example:

code:

List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8);

List<Integer> twoEvenSquares = 
    numbers.stream()
           .filter(n -> {
                    System.out.println("filtering " + n); 
                    return n % 2 == 0;
                  })
           .map(n -> {
                    System.out.println("mapping " + n);
                    return n * n;
                  })
           .limit(2)
           .collect(toList());

i finally got the pile of matlab/octave code that this guy wrote that I am tryin to extend and he basically didn't comment a single line lol

fortunately, there's probably 2-300 lines total so I guess figuring it out by trial and error won't take more than a few weeks but i knew as soon as they said a "math phd" wrote the program it would be a completely unannotated chore

i mean i got on node.js cause it seemed pretty hip and reminded me of when ruby was coming up in popularity.

but this kind of move just makes the whole bunch seem like uptight pricks.

they also call it Node.js� now with the little trademark sign now, like when people wrote Microsoft as micro$oft

look man, if you're serious, you need to read TAPL. you can skip the heavy theory sections because you're presumably not trying to get a phd (if you are, read the whole thing cover to cover). once you're done, you can move on to "advanced topics in types and programming languages" or you can say gently caress that poo poo and go in another direction. but right now you are not equipped to make that decision

you don't need to know anything about type theory (beyond "what is a type") to implement your own programming language or compiler. no one here is trying to make a serious industrial or research compiler. don't be so autistic.

i was working for apple as tech support once, though. every non-american customer did not give a poo poo about what features i had to tell them about (yay scripts). the american caller i once had was totally off her loving rocker when i told her about ~new features~.

and yeah, after two months of creating the thing i admit i'm invested into it, so that was a pretty bad humblebrag. sorry!
but i had to do the thing the program is supposed to do manually and it took me like two hours for 20 files or so. gently caress that.

i've gotten a recommendation for http://www.amazon.de/Clean-Code-Handbook-Software-Craftsmanship/dp/0132350882 - any thoughts there? if i'm gonna have programming as a skill i want to do it properly.

e: the scary thing is when you try to tell someone, anyone about what you're doing to get some sort of feedback or instruction and you're the only one who knows what you're talking about. didn't expect that to happen before i start my phd.
