Plato used the dialogue format because the exchange of views, the posing and answering of questions, showed that understanding is a living, dynamic process. He distrusted writing because the settled character of the written word makes it look as if truth can be fixed and made to stand still. It is worth remembering that this greatest advocate of the objective reality of truth also believed that our access to that truth was sustained in reasoned discussion.

— John Churchill, From the Secretary: Inspiring Conversations in The Key Reporter. Vol 67, Number 4. P. 2., Summer 2002

I think this is one of the strongest, most concise arguments in favor of free speech and open debate that I have ever heard. I’d never heard of this guy, but it seems he’s the secretary of Phi Beta Kappa. Sounds like a smart cookie.

(Posted at the very lowest possible priority on our blog because it doesn’t have anything to do anything, bears repeating, and won’t fit in a tweet.)

Bug with MSNBot/1.1 https://blog.nearlyfreespeech.net/2008/04/03/bug-with-msnbot11/ https://blog.nearlyfreespeech.net/2008/04/03/bug-with-msnbot11/#comments Thu, 03 Apr 2008 08:41:45 +0000 http://blog.nearlyfreespeech.net/2008/04/03/bug-with-msnbot11/ Recently, Microsoft announced the release of MSNBot/1.1, which is designed to save bandwidth and improve their search rankings. We applaud this effort. However, we’ve discovered what we believe to be a bug in MSNBot/1.1.

MSNBot/1.1 is using the If-Modified-Since: HTTP header to save bandwidth. This is a good idea; it allows the server to say “nope, hasn’t changed” rather than sending back an entire huge file and letting Microsoft figure out if it changed or not. Better for them, better for you.

However, when MSNBot/1.1 issues an If-Modified-Since: header, they’re garbling the HTTP request. Here’s an example:

GET / HTTP/1.1
Accept: text/html, text/plain, text/xml, application/*, Model/vnd.dwf, drawing/x-dwf
Host: www.xxxxxxxxxxxx.com
Accept-Encoding: gzip, deflate
From: msnbot(at)microsoft.com
If-Modified-Since: Sun, 17 Dec 2006 23:34:11 GMT
User-Agent: msnbot/1.1 (+http://search.msn.com/msnbot.htm)
Connection: Close

Notice the extra line between the If-Modified-Since: header and the User-Agent: header. If it were just a blank line, it would be mostly fine; the User-Agent: and Connection: headers would just be regarded as part of a useless request body. Unfortunately, that extra line is actually a space on a line by itself. To be sure, we confirmed that with tcpdump:

(Look for the “0d 0a20 0d0a” after If-Modfied-Since:.)

That’s a nasty violation of the HTTP spec, and causes the request to be dropped (and, on our system, logged, which is how we found out about it). We’d like Microsoft to fix this. 🙂

I’m posting about it here because, as with most large companies, the people responsible for MSNBot appear to be pretty well insulated from the outside world, no doubt due to several billion “your crap search engine lists my site as #372 when you search for cute kittens!” complaints. We don’t have a lot of members up in Redmond, for obvious reasons, but we do have some. And we have a bunch more who know people up there. So this is sort of a throwback to the days when mail was delivered by handing it to anyone who looked like they might be headed in the right direction.

So…. Where do you want to go today? Can you pass along a message when you get there?

Update: It’s resolved; see the comments for full details.
