I think it would be kewl to develop java assignments w/ maven. u could create archetypes for each project that the students start from. it could have spots for them to fill out the code and then tests they can use to verify their work before submission. you'd still have to read the code to figure out if their cheating or whatever, but it would be helpful from the students perspective and they'd passively learn bits of maven which you could later expand upon in higher level classes

is there ever a time in c where you want to be using c "objects" instead of just passing around pointers because passing around pointers sure seems a lot easier

like i guess if you want to avoid passing by reference so that everything is nice and immutable that has value

passing small structs by value tends to be faster then passing a pointer if you wanna be a SPEED DEMON

also copying is safer from a mutability standpoint - the receiver can't grub around with your copy of the data

this + unit testing for conformance

however, this would require professors to actually be capable of good software engineering practices

a few classes I took had this, but most of them were sample code + pdf +zip made in the 90s and never really updated.

quote:

Improper attention to the method of rounding can produce disastrous results. The Wall Street Journal (November , 1983, p. 37) reported on the Vancouver Stock Exchange, which created an index much like the Dow Jones Index. It began with a nominal value of 1,000.000 and was recalculated after each recorded transaction by calculation to four decimal places, the last place being truncated so that three decimal places were reported. Truncation to the fourth decimal place of a number measured to approximately 10^3 might seem innocuous. Yet, within a few months the index had fallen to 520, while there was no general downturn in economic activity. The problem, of course, was insufficient attention given to the method of rounding. When recalculated properly, the index was found to be 1098.892.

open source hippy types like to make fun of decorators and factories and such because they've never worked on a real world project project large or complicated enough (or at all) that such patterns become useful

it's not about using factories and teh like, it's about java programmers sitting there typing out ButtFactoryProxies manually like cavemen banging rocks together

the python standard library uses plenty of 'factories', but no one gives it a second thought because it's just a callback, and every class is its own factory

if your ButtFactory isn't just a function that returns Butts, you're doing something wrong (you're programming java)

it's not even just a conversion. that syntactic sugar translates to this:

code:

this(new StringBuilder().append(defaultValue).toString());

all of which does a big pile of poo poo behind the scenes. compare that to something sensible like this:

code:

this(String.valueOf(defaultValue));

where String.valueOf() just returns "true" or "false" and ugh the Java class library designers are the worst

if your ButtFactory isn't just a function that returns Butts, you're doing something wrong (you're programming java)

also, basic list operations appear to be a pain in the rear end in java, or at least they were before java 8. can't use java 8 at work yet so I don't have opinions about it, but it probably fixes some of this

like, I had an object foo in a list today, and I wanted to take all the objects such that foo.bar == "hi", and get their indices in the list

you know, like

code:

[i for i, j in enumerate(the_list) if j.bar == "hi"]

code:

IEnumerable<int> IndicesWhereBarIsHi(IList<Foo> foos) {
  for (int i in Enumerable.Range(0, foos.Count) {
    if (foos[i].bar == "hi") {
      yield return i;
    }
  }
}

which is better than it looks, because I included the function declaration. unless you're doing it mid-logic, then it is just what it looks like cuz you gotta declare a closure. you can and should probably define your own IEnumerable<T>.Enumerate extension method like the python one above though, which makes this cleaner, and lets you use fake sql syntax if you're an idiot

how do you do that in java? you do

code:

List<Integer> indices = new ArrayList<Integer>()
for (old-style for loop like a caveman) {
  if (Foos.get(i).bar == "hi") {
    indices.append(i);
  }
}

which sucks! especially since it tempts people to add logic into the for loop, and has mutable state and stuff like that
