Invalid SSL certificate








What happened?

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

What can I do?

If you're a visitor of this website:

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.

What captions?

Nevermind, this incredible work should be required reading for all information technologists. Thank you!

Mr Henry is correct. The capations are very unreadble.

Re the Art-Deco captions: I could read them no problem and I think they are cool. Like the cow-hunting, they enliven and enhance a very technical discussion by generating subtile pedagogical influences and associations.

Excellent summary

A comment not for Mr. Cantrill, but for whoever laid out the text in the figures:

The captions are virtually unreadable, when they ought to be clear. IMHO faux-Art Deco display fonts have no place in technical writing and they certainly aren't meant for dense text blocks like that caption in Fig 1.

I stand by my characterization: software doesn't emit heat -- the CPU executing it may (and does), but that is orthogonal to the software itself. (And one could envision Turing machines that had very different physical properties; the physical properties are those of the machine, not those of the software.

"That is, running software doesnt reflect light or emit heat or attract mass"

By this definition software may indeed have a physical manifestation...

- Software emits heat when it is being run (the power consumed (and wasted) by the hardware is a function of the amount of work being done by the CPU) - Software emits light when you are using a monitor to interact with it. - Software attracts mass when it is used to control a crane with an electromagnetic pick-up.
