The end of the world … and we do not care.

03-Feb-11

The IPv4 address space is officially exhausted … and we should not care. Internet addresses depletion reflects wired world Take this as a distinction between engineers and … the real world. The number of network-addressable objects connected to the Internet is climbing dramatically. The IPv4 address space is limited to 2^32 (~4 billion) addresses. For […]

Example of certificate creation with OpenSSL

02-Feb-11

If you need to create certificates for a test setup, the online examples and O’Reilly OpenSSL book examples – while instructive – seem rather awkward and obscure. The fault lies with OpenSSL (otherwise a great piece of software) and the mash of parameters between the configuration file, the command line, and interactive entry. The mash […]

WordPress hacked (again)

19-May-10

On around May 13 someone subverted my weblog to serve pharmacy ads. Annoying, but not otherwise a big deal, given regular backups. This hack was more clever than prior incidents Took me longer to find and remove the problem. I expect WordPress to be insecure. Looked at the source code early on. Like most PHP […]

Stepped on someone’s gravy train?

21-Apr-10

About five years back I wrote an article with my colorful speculations about a locally advertised business – Model Quality Introductions. To my slight annoyance, that one article is consistently popular. I was strongly tempted to delete the article, as I was not comfortable with slightly tawdry speculations as the motivation for folk to visit […]

Multiplexed FastCGI connections?

31-Jan-10

Does anyone use FastCGI with FCGI_MPXS_CONNS set to “1″ (for multiplexed connections)? Most FastCGI backends seems to be written for non-multiplexed connections. (Much simpler, so understandable.) The IIS FastCGI connector apparently does not support multiplexed connections. Writing a FastCGI backend that allows for multiplexed connections. Would be a waste of time if not supported by […]

Giving up HTML@W3C

17-Jan-10

Got the “status as Invited Expert in HTML Working Group” email. This I will let expire. Spent my time tilting at windmills, and do not see any point in continuing. The HTML Working Group at W3C is … far too much noise. The HTML5 “standard” is going to be a bloated monster, and there is […]

Efficient UTF-8 recoding and secure processing

16-Jan-10

An attempt to make a point… The use of UTF-8 on the web is common and increasing. Lots of data comes in as UTF-8, and inefficiency in UTF-8 data handling is going to have pretty pervasive impact. On the flip side, the creators of UTF-8 did a good job. There is nothing really complicated about […]
