This week I noted that certainly, even if I got new votes of 5 my articles average rating decreased, and I do not know why?
-For example my next article http://www.codeproject.com/Articles/545026/MVC-Basic-Site-Step-2-Exceptions-Management has 20 votes of 5 and 2 votes of 4 and the average is computed now 4.81, but it should be around 4.95, because( 5*20 +2*4)/22= 4.9545.
-For the latest article http://www.codeproject.com/Articles/576286/MVC-Basic-Site-Step-3-Dynamic-Layouts-and-Site-Adm the situation is even stranger, because I have 31 votes and all of them are noted with 5, and the result must be 5, but from this morning is 4.99.
Could you please solve this issue!

Votes aren't calculated quite so simply as that. Each person who votes has a weighting that gets applied, which is based on their site reputation.

1)I know this, but if all votes are 5 why the total result is not 5 ?
2)Also if I got a new vote of 5 why the total result is downgrade ?

I asked this once, and it was because of caching.

I have an article with 31 votes, all of them are 5, so why the total results is 4.99 and not 5?
Could you explain this?
Please correct this!

If I would vote 4, and then 5, then it's still because of caching.

Thank you for your answer!
I read that document before to create the bug report, but this do not explain both examples given by me!

For the 4.99/5 bug, I won't name any names but I think someone *cough*MhrisCaunder*cough* needs to reread this article:

As for being clever, all you'd need to do is a truncate instead of a round to nearest on a value whose actual error that was only in the last bit or two of the mantissa.

The voting doesn't work that way, as you've seen by reading the Rating FAQ[^]

It's 5.00. You more than likely saw an old cached value.

When I'm trying to hire, my company tells me to use LinkedIn to source candidates. Of course, Code Project is an amazing community of skilled people and would be a great source. I didn't see a jobs posting board for the community. Has this been considered? Does it exist and I just can't find it?

There was one, but it got taken down some time ago (AFAICR)

It's nice to see articles recognized for being well written and insightful. Having the best article of the month medal is really nice...
But how about put a small mention on all good articles that have competed for best article of the month but did not win. It doesn't need a medal, but a small gray label near the rating would please a lot of contributors and I think it is well deserved.

Hi CP admins,
A few months ago, I reported a bug, and because of that bug, I got 350 Participant points when I updated my settings. This bug is fixed already, but now I realize me: I've updated my settings 3 times before the bug was fixed, so I've 1050 Participant points too much!
Can someone remove these 1050 Participant points?

Your honesty makes you worthy of keeping those points IMHO.
Be excellent to each other. And... PARTY ON, DUDES!

Shhh!
(In all seriousness I've been meaning to run a recalc which will fix (and trim) the points.

Okay, maybe it's not that serious, and I've probably posted this before, but I can't believe a place like Code Project has no Python section. It's pretty much my 'goto-language', very popular, and a google favorite. Remind me again why there is no Python section?
I queried another favorite site of mine about an "embedded code" or "Arduino, ATMega, etc." section and was told that there simply wasn't enough time or man hours to implement it, and that tags would be better suited for this, and I should just tag C projects with the proper "embedded" tag. Is it something like that going on here? I wouldn't know where to start with a "python"-tagged post. There's not even a "Scripting" section, though things like Javascript have a home in "Web Development".
I see python-tagged articles, and a few python quick answers in "General Programming" but that doesn't seem right.

There just hasn't been that great a demand for Python here unfortunately. You could always ask questions in Quick Answers and tag them with Python. Also, could I ask a favour? As you write in Python, could you write some articles on it for Code Project? We are always after new and interesting material, and this could be a great new addition to the site. Who knows, you could be the person who stimulates enough interest in Python here to get that coveted Python section added.

Ahh... I see. I thought everyone loved Python  . The article thing, I'm not so great at, but if I think of anything good to write I definitely will. Thanks for your reply,
-Chris
