And if you're using regex you're gonna have a bad time.
So much of what I do involves regular expressions and text manipulation, I just have to ask you: ¿Que?

ctrl+shift+v (not ctrl+v) should still work in putty, I think. I edited in some other options in my other post as well. I think ctrl+r should allow you to insert text from other files into the currently open buffer.
My new project has me working in Linux a lot more and I'm quite enjoying it. I only knew a handful of commands but now I'm starting to brush up on my command line experience.
But vim... Man... That's going to take a bit.
Do the vimtutor tutorial every day for a week (do it twice a day, once in the morning and once at night if you are super keen). By the end of the week you'll be proficient.
Vim has a reputation for impenetrability that was built up during the editor wars and has never really cleared despite being trivially easy to learn and understand.
It's not that it's difficult to understand, it's that the hotkeys are obtuse and it's anything but user friendly. I mean, look at your own advice. Do the tutorial (the tutorial!) twice every day for a week and you'll be proficient. Yikes!
I use vim sometimes but it kinda weirds me out how vim zealots seem to focus on I must input all this text fasterrrrr when usually for me any barrier to me writing code isn't on how fast I can write the text, but how fast I can figure out what I want to write...

I don't mean proficient as in "you'll be able to enter text", I mean proficient as in "you will be really good at using Vim, including a firm grasp on the most powerful and useful productivity features". I wish every text editor/ide came with a tutorial to make it easy to learn the good stuff that you can do.

I love recursion so much I'll use it even where there isn't any reason to.

It's not that we can't read it, it's just that I hate it. Same with regex. Though at this point I can't read regex anymore so I've got that going for me.
Really though, recursion should be "well there really is just not a better way to do this." (some of the more advanced data structure stuff like trees use it)
If you're using recursion for something like fibonacci you deserve to be strung up and stabbed.
And if you're using regex you're gonna have a bad time.
I had seen basically no recursion whatsoever until I took an algorithms class on Coursera, and trees and stuff are exactly where! Lots of little recursions like:
public void put(Key key, Value val) {
root = put(root, key, val);
root.color = BLACK;
assert check();
}
// insert the key-value pair in the subtree rooted at h
private Node[b] put(Node h, Key key, Value val)[/b] {
if (h == null) return new Node(key, val, RED, 1);
int cmp = key.compareTo(h.key);
if (cmp < 0) h.left = [b]put(h.left, key, val[/b]);
else if (cmp > 0) h.right = [b]put(h.right, key, val);[/b]
else h.val = val;
// fix-up any right-leaning links
if (isRed(h.right) && !isRed(h.left)) h = rotateLeft(h);
if (isRed(h.left) && isRed(h.left.left)) h = rotateRight(h);
if (isRed(h.left) && isRed(h.right)) flipColors(h);
h.N = size(h.left) + size(h.right) + 1;
return h;
}

If you ever need to talk to someone, feel free to message me. Yes, that includes you.
Like, there's places where recursion is great, and should be used. There's also tons of places where recursion is an ok idea, until you factor in all the edge cases. Problems arise not with the creation of solutions for the latter, but when you go back to code that was written years ago and you have to find out what it's actually doing/why it's breaking.

I'd argue that the same thing is true with iterative/imperative code, if not worse, because (uncontrolled) state is innately more difficult to reason about especially if you "have to page it in" after the fact.

Question: Is there anything more boss than hex editing a file to remove a single byte to turn it from an invalid gzip file to a valid one thus proving you are right?
Answer: No. There is nothing more boss than that.
Looks like funding was cut for my old project yet again. Even more than before... I'm sorta lucky that I'm on this security project right now but I hear there are a ton of jobs in danger right now.

Was that the Sedgewick course?
Yeah! I thought it was really great. Especially the programming assignments -- very satisfying to ace the autograder's enormous battery of tests.

I thought it was great too. People may laugh at the idea of an algorithm course in Java, but he did a fantastic job. I took it as a refresher, but I definitely learned a few things.
It also had the side effect of catching me up to date with the current state of Java at the time. So much material would have been painful prior to the introduction of generics, for example.

If I need something else, that's what SCP and sublime is for

I have done this with sublime I'm pretty sure.

Well, maybe. It seems likely that I'll probably use a proper IDE at my next job.

Haha, did it exactly the opposite today.

That sounds like a lot of effort.

Eclipse CDT really isn't that bad.
I dunno, my coding has never really felt limited by my text-entry speed and I'd rather have the easier navigation.
Looks like I'll be there the week of April 14th for a Microsoft BI course.
I don't mind Eclipse CDT either. In fact I was just using it for the debugger UI.
But for day-to-day development it was just impractical due to the size of our codebase(s).
My next gig will be Android focused, so... yeah.

If I wanted to union a set difference except the intersection of jim and joe bob, I'd use a fucking library function. In a sane world.
