Instead of subscribing to a URL, you subscribe to a site, and meta code in
the head of the sites pages informs your browsers RSS auto-discovery
mechanim that RSS exists to subscribe to. It removes the need to subscribe
directly to an RSS file URL that can change and create an invalid source in
thousands of subscribers shopuld the actual RSS location be changed by the
owner.

Excellent, though very techncial explanation of it all here.

Hi John, and thanks for the response.

The meta code must be placed in the head section , correct ?

The meta code can contain an RSS url , correct ? Does it have to ?

Does the presence of the meta code cause the browser to examine / make a
request for every link in the page to determine if it's an rss feed ?

Yes

For auto discovery it should contain a link to an ATOM file (index.atom for
example) or an XML file as per the spec.
Does the presence of the meta code cause the browser to examine / make a
request for every link in the page to determine if it's an rss feed ?
I dont believe so, the meta to the atom or xml file contain the information
so that should be enough for the browser to work with.

Hi. This post follows "does python have useless destructors". I'm not an expert, so I hope what I will write is meaningfull and clear. Actually in Python there is no possibility to write code that follows C++ RAII pattern. Of course Python objects are not statics like in C++, but in C++ the auto_ptr class is used for enforcing this pattern for dynamical

I'm using the following in a page that I'm testing in Mozilla: p.actionLinkBlock {border: 1px #000000 dashed; padding: 0.2cm; width: auto} But the dashed border is extending to the right-edge of the screen. I want it to only extend as far as it needs to to nicely contain the content within (a couple of links). Is width: auto the wrong property to do this? Is Mozilla rendering the style wrong?

Hi, I am running into a problem of mixing UICulture = auto and allowing users to select culture using a dropdown list. I am detecting a querystring, "setlang", and when found, setting the CurrentUICulture to what's specified in the querystring. Since I want to allow UICulture auto detecting, I add UICulture = "auto" to page directive on each page.

at work they decided to center divs thus: body {text-align:center} #content {width: 612px; text-align:left; margin: 0 auto 0 auto; } this works fine in IE & FF, EXCEPT in FF it doesn't work if I change 'auto' to 0 for left and right margin values; I have to leave those at 'auto'.. so I would like to know what exactly means 'auto' -- what value it represents exactly (and does it apply for all elements/values you might apply 'auto' to?)

I currently get asked about my usage of "auto". What is it for? The keyword is clearly superflous here. In contrast to the huge majority of C/C++ developers I write definitions very explicitly like that: int main(char argc, char *argv, char *env) { try { auto Exception mainException(1); mainException.setErrNo(42);

Hi, I've encountered a strange problem with Firefox which I don't have any idea how to resolve. To the point: I've <divelement with a style "height: auto" and I want to retrieve this value ("auto") in JavaScript - however instead of getting "auto" value, I get calculated height. In IE and Opera it simply returns "auto". Any ideas how to check in Firefox if element height was set to "auto" ? I'll be grateful for any help.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
