2011 Sep 20, 7:17There's no race between posting to a web worker and the web worker setting up its message handler as long as the web worker sets its message handler in the first sync. block of code that runs in the
web worker: "Basically, once the initial worker script returns, the worker's port is enabled and the normal message port event delivery mechanism kicks in (including dropping unhandled messages on
the floor)."

figure out? Or should we leave things as they are, knowing there will be more blocking events but also knowing that we can solve them easily?"

site that the user regularly visits... The client secretly marks the connection as a Telex request by inserting a cryptographic tag into the headers. We construct this tag using a mechanism called
public-key steganography... As the connection travels over the Internet en route to the non-blacklisted site, it passes through routers at various ISPs in the core of the network. We envision that
some of these ISPs would deploy equipment we call Telex stations."

as the scope of authority or privilege by user agents. Typically,
user agents isolate content retrieved from different origins to
prevent malicious web site operators from interfering with the
operation of benign web sites. In addition to outlining the
principles that underly the origin concept, this document defines how
to determine the origin of a URI, how to serialize an origin into a
string, and an HTTP header, named "Origin", that indicates which
origins are associated with an HTTP request."

textfiles, software archives, and historical computer networks into a multiplayer adventure game." Also, see all the accounts of people finding their teenage selves in the game.

As it turns out the
WPAD Server Fiddler Extension I made
a while back actually has a non-malicious purpose. Apparently its useful for debugging HTTP on the WP7
phone (or so I'm told). Anyway I took some requests and I've fixed a few minor bugs (start button not updating correctly), changed the dialog to be a Fiddler tab so you can use it non-modally, and
the WPAD server is now always off when Fiddler starts.
