Invalid SSL certificate








What happened?

The origin web server does not have a valid SSL certificate.

What can I do?

Please try again in a few minutes.

If you're the owner of this website:

The SSL certificate presented by the server did not pass validation. This could indicate an expired SSL certificate or a certificate that does not include the requested domain name. Please contact your hosting provider to ensure that an up-to-date and valid SSL certificate issued by a Certificate Authority is configured for this domain name on the origin server.

this is a true senario, am really interested on how the information has just been flowed.and i love the fact that the IRs has been expanded in such a way that it is well understood. i personally i have found the information that i was looking for. finally i would like to know more about programming specifically in object oriented programming thank you

Here's how NQP's QAST (https://github.com/perl6/nqp/blob/master/docs/qast.markdown) informally stacks up against your bullet points:

" Completeness. Written in NQP. NQP is a simple functional/OO lang for writing compilers. A QAST tree consists of a tree of NQP objects made from about a dozen classes corresponding to very generic intermediate things (eg compilation units, closures, calls of closures, literal values, ops).

" Semantic gap. Er, no idea.

" Hardware neutrality. NQP is designed to be highly portable. It targets both existing VMs (JVM, CLR, etc.) and its own custom VM (MoarVM) which is itself highly portable.

" Manually programmable. QAST is just a tree of object declarations written in NQP.

" Extensibility. Extend the classes already defined for QAST or write new ones. Or write new NQP ops.

" Simplicity. Yeah. About a dozen types of object written in a simple language (NQP).

" Program information. QAST annotations.

" Analysis information. QAST annotations.
