Problem type

quantum is taking ICS this semester, but is too busy working on this site to do the homework.

His homework for this week is to print out the message Hello, World! - with the same capitalization and punctuation. If you do his homework for him, he'll gladly give you one point as a reward.

I give up

After making 30+ attempts over five hours in four different languages, I'm speechless. The performance measurement needs some serious work. I posted the exact same code in the exact same configuration but somehow the performance was off by 100x+.(python 2 "print "Hello, World!"")

How?

There's me with assembly trying every bit of performance voodoo magic known to man. And then there's that guy with python2 four places above me who simply did "print 'Hello, World!'". Then comes the depressing realization that I literally spent more than two hours on a hello world program...

Look on the bright side. You just made hello world run in only 4 kilobytes.

New Title?

Why does the title come up as 《Hello, World!》程序 when you try to search for it in problems?

Highly obscure bug regarding newly implemented problem translations.

Occasional server 500s

We're currently rewriting parts of the site, so you might get occasional 500 errors when we restart it periodically. Refreshing the page a couple seconds after should be fine.

New status messages

Since we've recently added extra info to RTE codes that some have found to be a bit confusing, we've made a page about status codes, status messages, and what they mean.

If you have any feedback or still have doubts about any of the messages or when they occur, please let us know here.

Just a heads up, we're currently testing out a rewrite of the judge, so expect a couple of IEs here and there. Thank you for your understanding.

Update: a number of problems were updated today, and are now solvable. All broken problems (aside from three interactive problems) should be fixed now.

Javascript

How do you output in JS? I've tried document.write(), console.log(), and even window.alert()

See the runtime info page for details.

Thanks. Was unaware that that page existed.

An Idea

I wonder if it is possible to have a hello world hard mode wherein we would have a 0.01 second time limit. Or is that simply unfeasible?

The best submissions does this already. Besides, it is trivially doable in some languages, most notably assembly.

Like in Java, for instance, System.out.println() takes 0.043.

Unfair

This is too challenging for most people. It's unreasonable to think you can keep the memory under 64M. Petition to remove this problem from the Internet.

After carefully rereading the problem's requirements over and over again, I have concluded that you are in fact correct. I will gladly sign such a petition, if only to ease the pain one must suffer staying up long nights trying to complete this unfeasible project. My sentiments out to all families who have fallen victim to this terrible request.

I'm pretty sure you're the one who forced them to create those guidelines.
