ehh 600 == 583, it's close enough

trichoplax

I got 583 by assuming that exclamation mark didn't mean factorial

oh god D:

Nathan Merrill

its like daylight savings, but instead decade savings

they bounce back and forth a couple decades every so often

*century

Jan Dvorak

583 years is a couple of decades

trichoplax

Yes, "couple" means different amounts in different places

In England it means precisely 2. In Wales it means several

well i mean... "century" has more comedic effect than "decade" :P

Decade sounds more like daylight

in that case why is it closed

@NathanMerrill I don't see that working very well. One user's hard is another Dennis's easy.

@TuxCopter if you remove "question:" I'll tell you that arrays are objects in Javascript

Nathan Merrill

its not going to apply perfectly to you, but it'll still give you a great estimate

but that's true of all ratings

like, you might hate a 5-star item on amazon

but I bet you're more likely to hate a 1-star item on amazon

Dennis

Dunno. Both 1-star and 5-star items usually have only one review.

Anonymous

@NathanMerrill It'll give an estimate. Whether it's great or not depends on the user. My previous statement goes two ways: different people will rate challenges differently, and the average may or may not be relevant to a user based on their skills and knowledge.

Erik the Outgolfer

well, code-golf isn't the same as code-golf regular-expression, the former requires you to golf code, the latter requires you to golf regex

regex can't add two numbers or test pr... wait, it can do both.

Erik the Outgolfer

I was about to ask if regex can do string comparisons ("ie is this string equal to that string")

nah, regex (in the pure form), can't actually add two numbers

@DJMcMayhem I don't play video games very often recently. Sometime the occasional NetHack, but that's about it nowadays

DJMcMayhem

@KritixiLithos I've played both a fair bit. MK8 feels more balanced to me (harder for good players, eaiser for bad players), and the 200CC is brutally hard. The biggest difference is the removal of the automatic transmission, but other than that they're fairly similar

I've only recently (two years) begun to use manual on MK Wii. It's especially good with bikes

DJMcMayhem

Yes, but there are some things that make it easier for beginners too. For example, falling off isn't as big of a punishment (you can keep your items and you are rescued by lakitu earlier)

Kritixi Lithos

can you fall off while gliding?

I'm much better at MK wii. I can usually take 1st without too much trouble in a 150CC grand prix with CPU on hard. On MK8 with 150CC cpu on medium, I'm usually just happy to make the stands.
