Yes, Charles Babbage went to France and saw a Jacquard loom that created a multi-color silk portrait of Napoleon using over a million cardboard rectangles into which holes were punched to regulate weaving.
But, I'm not sure I'd call that digital.

It's binary - on for a hole, off for the absence of a hole. So it isn't analog!

I'm not sure that the Jacquard Loom can be considered digital. Certainly the Loom meets the test of "fully programmable" in the sense that, up to its mechanical/physical limits, it could render any design that could be made with the thread at hand.
And, the cardboard "program" (sewn together cards) was, indeed, rolled off a spindle in a sequence, as I recall (based on reading over thirty-years ago). No undo, no goto, no recursion: the ultimate declarative language ?
Would a true "digital" computer have to have a memory-store, and the capability of some kind of branching based on conditional evaluation, and looping ? I think so. I'm trying to remember the names of those three Italian theorists who stipulated that those three attributes were essential for a Turing machine, but drawing a blank.
I'm inclined to think the true "computer" in the case of the Jacquard Loom was the human intelligence that figured out what cards were needed, and how they should be punched.
cheers, Bill

Quite right, I was aware of the German work. Forgot it was called the Z3. The Nazis didn't see what it was good for.
Destroyed by bombing if I remember. Another first.

Interesting article.
I've seen the one at the Smithsonian, it's pretty cool.

A major not-really-historical point is that some countries' armed forces manage to actually keep things secret, no matter how much money can be made from selling them or claiming ownership.

Well, how about the Antikythera Mechanism circa 3rd. century BCE (Before Common Era). It's age has, recently, been reported to be at least a century older than previously thought: [^].
The Antikythera Project and Musuem: [^].
Another Antikythera site: [^].
Videos: [^].
But, it's not digital.

Walter Isaacson's "The Innovators" contains an excellent history of early computing and the individuals involved.

As many of you know, I'm with the Swiss Air Force (and will be until March '15).
I know that some of you are gun enthusiastic, and decided to post a little writeup about the Army guns I used during the past few months.
I initially got the SIG 550 assault rifle, but since they found me a good fit as SFC I was given the SIG P220[^].
The rifle is very precise over a distance to up to 500 meters, and reasonably easy to keep clean. I still like the P220 better, though. Of course you can't really compare these two directly, one is an assault rifle and the other one a handgun, so this judgement might be because I like handguns better. However, the P220 is very neat - Precise, reliable and lies nice in my hand. Went shooting it yesterday, 20 rounds on a 10 point target. Got 181 points out of 200, not too bad that it was the first time I shot this gun (I used the instructor's gun the time I went shooting before).

181 of 200 ain't bad for a first time.
Are these standard competition targets?

I don't know what you call "standard", but they're standard in Switzerland.
Edit: It's closely looking to this[^], but not that narrow.

Standard Precision Target looks like this[^].
The outermost ring is 500mm diameter and the black part in the middle (7) is 200mm diameter.
