For something like Jekyll, this also applies to the input. I use it for a couple of sites and, in both cases, the sources are Markdown files (easy to edit with your favourite text editor) stored in a git repo. When I'm working on updates, I run 'jekyll serve' locally and get a copy of the site on the loopback. When I want to push them, I can do jekyll build and then rsync the results to the web server (or do something more clever if I'm less lazy and want atomic updates). The entire change history of the site is stored in revision control and the revision control system contains everything necessary to recreate the site at any point in its history.
I've yet to see a CMS that allows trivial rollback to earlier versions of the site or which makes it easy to store the content in such a way that a compromised web server can't damage it.
I'm not sure I agree with your first premise. There are fairly trivial combinators that you can write in lambda calculus that are conditional flow control (i.e. reduce to either the left or right lambda expression based on a value). The implementation of ifTrue in Smalltalk (loosely) follows this model.
More mundanely, the statement is obviously false because a language constructed with the basic arithmetic operators and unconditional branches is also turing complete.
Only if the unconditional branch is a computed branch. Otherwise how would you implement a program that either terminates or does not terminate based on user input? The example that comes to mind is the x86 MOV instruction which, with a single unconditional backwards branch is Turing complete, but this relies on several other aspects of the surroundings that allow you to implement a conditional branch (or, at least, a select, which is morally equivalent).
The simplest Turing-complete instruction set is a subtract-and-branch-if-not-negative instruction, but this is a conditional branch.
I agree that conditional flow control is slightly too broad a requirement, as it depends on an imperative model. Conditional execution depending on input data might be a better way of phrasing it.
The serial rather than episode format was a brave choice for a hour long prime time show at the time
You mean it was brave of them to say 'this format is working well for Babylon 5, I wonder if it will work if we do it with a series with a lot more brand recognition and a much bigger budget?'
Because we have had colder temperatures with more CO2 in the past
This is true, but those times also had significantly higher ice concentrations. Paint a big chunk of the ground (and sea area) white and you'll see the
the earth is primarily a self regulating eco-system leading to stability
If you can say this with a straight face, then you have no idea of the history of the climate.
I run my own DNS. I think it is strange that there is no easy DNS server available for Windows. And by basic I mean Install and forget (perhaps point your DNS to 127.0.0.1). So no additional settings. Just a very basic caching server for a single user.
Doesn't Windows come with one of these built in? I might be remembering from the Server version, as it's quite a few years since I last ran Windows, but in Windows 2000 it was something you could enable in the services management interface.
One of the big supermarkets in the UK used to have warnings on the backs of peanut packets saying 'Warning: may contain nuts'. I was confused by this until I found a packet that had been filled entirely with air due to an error at the factory. Then I understood the warning.
Although on further reflection, it's still a bit confusing as peanuts are peas, not nuts.
