The bziped versions of the summary files are corrupted. Don't know if they are generated that way or if the download is so slow that errors are introduced. It has been like this for the last 24 hours.

is that's what's breaking your wonderful stats?

Posted: **Mon Apr 12, 2010 10:17 pm**

Yes, that is it. And my code is not prepared to handle the uncompressed version as it takes very long to download in my ADSL connection. And thanks for the wonderful.

I hear a lot of praise for your stats from my team mates. They really are very well done.

Already 30 hours KakaoStats not upgraded. Someone should do something. Very useful and detailed statistics. We lack. Where is the problem, in Stanford or servers Kakao?

Posted: **Tue Apr 13, 2010 6:09 am**

The problem is with the bzip files that Kakao's parsing, as he says it could be the result of the connection between him and Stanford, or it might be a problem @ Stanford's end. Has anyone else tried out the bzip file? (I would attempt to, but my file DL is shaped to 5kB/s during the day).

Unless Kakao did a dummy thing... My money is on server. I would thing Kakao's connection has not changed. YMMV

I managed to download the file & didn't get any problems unpacking it; there could be a problem with how it's outputting: I'm hosting the unzipped file if anyone wants to PM me I can give you the link. (don't think you'll get the whole download though - I'm on adsl lol.

Maybe the problem is fixed. Now the statistics are updated.
Thanks.

k1wi, did you download this one:?

http://fah-web.stanford.edu/daily_user_summary.txt.bz2

How did you test it? I do it like this:

$ bzip2 -t daily_user_summary.txt.bz2

Now I suspect the problem is on the path from Stanford to my modem since the download is very slow. This is my traceroute. If someone could interpret it:

A trace route is not going to be able to find the link that is corrupting a transmission. Too little data is being transfered. All you will be able to determine is the path taken; how long it took; and if someone dropped the ping.

The first thing to be done if you find corruption is simply download it a second time. With a little luck, the issue was temporary and won't happen a second time. If both files are identical then most likely the corruption was from the source (Stanford). If the files differ then it is likely that the problem occurred after the file left Stanford.

gotta love French computer error messages!

Hey Kakao - I saw your site's message. I hope you can get it fixed without too much work. It's a great service.

Ditto. Nothing bad about the other stats sites but I just like yours better. I hope this can be resolved for you. Can you detail the specific problem you have with the downloaded files and maybe someone here can host them for you as a relay to avoid the issue?
