I've decided to have PEG Judge bugs tracked on Launchpad (just so they'll all be in one place, as there are so many bugs that I can't remember them all).
If you've reported an issue in the past and it hasn't been fixed, [url=https://bugs.launchpad.net/peg-judge]report it here[/url].
Before you ask a question, please do the following:
[*]Java users: make sure you name your class the same thing as the problem code.
[*]Make sure your program works correctly on the sample input(s). It must match [i]exactly[/i]!
[*]Indent your code and use logical variable names if you want help.
[*]Think about large or tricky test cases, and ensure your program can handle them properly.
[*]Java users: if the answer to your question is [i]xyz[/i]Exception, that means we deem the bug sufficiently trivial so that just knowing what the exception is should allow you to fix it.
[*]Try to fix the problem yourself for at least 15 minutes before giving up and asking for help.
[*]If you think the test data are incorrect, please take a moment and consult the Best Solutions page to see how many people have gotten the problem Accepted, and then ask yourself whether it would not be arrogant to conclude that your program is correct and everyone else's programs are wrong. (Of course, problem setters [i]do[/i] screw up sometimes, by adding trailing space, or something like that; this may bite you if you're using a different programming language than everyone else. If you suspect that this may be the case, don't hesitate to speak up. However, be forewarned that this is almost always [i]not[/i] the case whenever the input consists entirely of numbers.)
[size=18]On asking questions:[/size] [size=14]post on a problem page if [i]and only if[/i] your question is of relevance to everybody (for instance, a clarification question). [b]If your question pertains only to you[/b] (such as if your program doesn't work, or if there's something you don't understand about your programming language), ask it on [url=irc://wcipeg.com]IRC[/url] on the channel #help (a [url=http://wcipeg.com:9090/]web client[/url] is available), or post it on the [url=http://wcipeg.com/forum]forums[/url]. We'll do our best to help you, but please note that responses on IRC are usually not instant (just as replies to comments are not instant), and your question might not get answered at all if nobody has enough time to help you (we're (almost) all students, here).[/size]
[size=16][b]PEG Members[/b][/size]: Please do not post for help here. Instead, use the in-class resources and email your leaders for assistance.
If at any time you post a question asking for help in the comments section of a problem, we [u]will[/u] delete and ignore it.
Also note: programs may behave differently on the judge and on your computer, but this almost always happens only because you have done [url=http://wcipeg.com/wiki/Judge:Help#Execution_discrepancies]Something Bad[/url]. Please review this checklist before assuming there is a grader bug and posting a comment about it.
Thank you for your cooperation.
The IRC web client now supports SSL as well. [url=https://wcipeg.com:9092]Use it[/url], if you care.
[b]Update[/b]: This no longer works---I bet nobody's using it, and I'm too lazy to reconfigure it. The non-SSL one still works, though.
Hmm, don't know if I can trust your certificate. ;)
it's also listed [url=http://t3nsor.wordpress.com/openssl-key/]on my blog[/url], in an attempt to convince people it's actually me
I was trying to access PEG during the day, but it gave me error messages. However, it suddenly worked right now... Did anyone get the same problem or was it because my computer didn't function properly...
Host was being incompetent with migrations. Should be fine from now on.
After noticing a particular submission from someone (you know who you are), I feel that this message needs to be heard, particularly by Churchill PEG members. The admins of this site are really not dumb. Looking at a submission, we can easily tell whether someone earned the points for a problem legitimately. We realize for many problems on the PEG Judge, solution descriptions or even solution programs can be found online. There is nothing we can do to stop you from giving yourself a hint by, for instance, reading a few sentences of a solution PDF, and then implementing the program on your own.
The problem arises when you copy somebody else's program, change some variables, add a few sporadic comments, and submit it in one go for a perfect score. This is blatantly cheating. We don't really care about this for public users. It's their own programming skills that they're trying to improve; there are certainly no merits to copy-pasting code all day long to gain imaginary points on a website. However, for aspiring programmers in PEG consistently competing with each other (for ranks, rewards, trips, etc.), points DO mean something. Thus, we must be particularly strict with enforcement of this policy.
It is very unfortunate that not only did you try to illegitimately obtain 50 points through 1 problem while your peers are working so hard to even earn 30 on several, you decided to brag about solving it on your own in the comments. It is even more unfortunate that you chose to do this right after we all discussed proper use of the PEG Judge last Wednesday. In the past, our leaders/teachers would not have hesitated to kick out students for such offenses. For this one time, the score for your submission has been set to zero. It's never happened before (and we don't plan for it to), but if similar events persist, you just might start seeing negative scores for people's submissions. Learn to be grateful that such a wonderful practice tool is available to you.
TL;DR - Just get points legitimately; we're reaching a limit on warnings.
Submissions and comments from today (Oct 28) were lost due to an issue with the database.
We apologize for the inconvenience. Please remember to always back up your programs locally in case of similar events in the future.
I can't submit anything in Java.. I get an error message saying : Compile failed
sh: cavaj: not found. what does this mean?
I'm experiencing the same problem with my Java submissions.
I think Haskell is broken. Even the sample code does not work.
When submitting a java code, I was faced with this error message and it apparently was not because of my code. Could someone fix this issue with the compiler?
When using regex_match() in C++11, the output yields:
./a: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by ./a)
./a: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by ./a)
Thanks for the report. I'll look into it.
I changed the C++11 compilation to use static linking. Maybe it works now.
