A lot of hate for Java in this thread. Just want to try to counterbalance it with some things that I, personally, like about Java. 1. Java enums 2. Java's generics, especially covariance/contravariance with wildcards (erasure real

Type erasure gets an unfairly bad rap. Yes, it makes reflection difficult sometimes. Yes, it doesn't play well with value types. But other than that, erasure is a very powerful concept.

What I was trying to get across with my example was that you can define a standard, reliable way to perform equality checks on type-erased values without having equals on the root object. Granted, it looks a bit wonky, but it provides saf

Member-by-member sub-equals might make more sense in some situations, but not all (as the article discusses, equality is context-dependent). By making equals() an instance method, encapsulation is broken by tying an external concern (equali

As much as null is considered the "billion dollar mistake", personally, I think that Java giving Object a virtual equals() and hashCode() was an even bigger mistake. NPEs blow up loudly in your face and are fairly easy to lint for

As I mentioned elsewhere in this thread, leaded paint can be a major health hazard in older homes.

My guess would be for having to properly handle and dispose of leaded paint in older homes.

I think the idea is that low-interest rates cause investors to push companies to adopt riskier behavior and that easy credit enables said riskier behavior.

Implementations as in .Net implementations? Or implementations as in other languages' implementations? As far as .Net goes, I've not looked around. I feel like it would be somewhat of a fool's errand to develop an alternative

Sure, but if you're going to go that route, why not just say "the entire computing system at a whole is just a state machine, so what's the difference"? Threads provide a very privileged form of state machine that are ti

Genuine question: looking at that graph, it's saying that median weekly earnings reached a peak in 2009 then dipped 2010 through 2013. I find it rather counter-intuitive that a peak in median earnings would occur during the recession.

A decay function on reputation might help, but I think the real issue is treating reputation as a precise indicator of user quality. But is a user with 40k rep really meaningfully better than a user with 35k rep? An idea that I had was to h

That brings to mind an interesting idea for an IDE: having one big virtual file that you edit, which gets split into multiple physical files on disk (based on module/class/whatever). Although, thinking about it, there are some lan

Almost, but not exactly. For example, you still can't have multiple symbols in the same scope that vary only by case. Which, personally, I'm okay with.

VB.net is case-insensitive, and probably more popular than you think[1]. I think that case insensitivity actually does make sense when working with symbolic identifiers. I've seen justifications for "Foo" and "foo"

That's pretty much the position that I've come to concerning copyright. Individual works last 20 years or until the first author's death, whichever is greater. The rights are assignable but non-transferable. Corporate works l

by lazulicurio 7y ago
Personally, I prefer to never use git pull, and instead use git fetch then manually merge or rebase as appropriate. It's one more command, but I find it helps me visualize exactly what I want to happen.

There's still plenty of ways reference resolution with NuGet can go wrong, even without the GAC. For example, because NuGet allows packages to import .props and .targets files you can have packages that add arbitrary references that do
