Module development and code questions

I was stumbling through the handbook looking for info on using the CVS. I thought I'd examined most topics, and finally tried the "Bazaar-NG" topic.
http://drupal.org/node/45368

So if this is the CVS software, what is ViewCVS? Are they the same? Are they alternatives?

Is there a module that is available that can put random or select images on the front page (in the center) with comments?

Hi
Using 4.7b4

I started off making a copy of the dashboard module just because it's short and simple and using a bit of the how to create a simple module tutorial.....

Now the module (lag) half works in the <>/module/dashboard folder - that is it appears on the create content page, but not in the create content menu....

However when i move it to the <>/module or it's own folder, it doesn't show up in either the create content menu or on the create content page...

Here's the module code in case you care to look.

Are there any filesystem modules available in Drupal? I mean, some module so I can edit core Drupal files through web-interface.

I am using the banner maodule and was wondering if anyone had successfully used banners from an external site (ie full urls instead of hosting the banners myself)?

The reason is that some affiliate banners i use will change according to their latest offers, and get tracked on the affiliate site...and as such they need to remotely hosted, not uploaded to my drupal site.

Any ideas?

When I use aggregator, to get rss I get error.
I guess it is a problem of encoding. So I tried to modify the problem. But I couldn't.
The aggregator and xml parser seem to programed well.

When I get rss from here
http://www.hanbitbook.co.kr/sync/rss_network.xml
I got error. It is written Korea and euc_kr encoding.

Is there any solution? I tried to find same problem in this site. But it seems that there is no article.

These are parts of error messages.
