Building a Telegraph Using Only Stone Age Materials 238

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"

I totally want them to make a Footfall movie and really use a Project Orion craft. Usually they just have a technobabble solution for how the humans beat the aliens, but in that case you didn't need to use technobabble. The humans really did have a big stick, they were going to kick your ass, and there wasn't anything you were going to be doing about it.

On a final note, I guess I really should see if it's possible to change the account name, because when I post something funny and people who don't know go "Dude! That was great!" I'm caught between laughing at the incongruity and going *sigh*. It makes for some interesting back-and-forth. And this account has great karma and lots of equally-great fans.

Why sigh at the incongruity? Sometimes I can't remember the name of the child who's attention I want, much less worry about the gender preferences of someone who I can't see and don't even know. Respondents are likely to say "Dude" without even having made a decision about whether your login is gendered male or female.

Life is too short to assign weight to the random stuff other people say.

Don't get me wrong, I'd love to do this, but since we've been taking our kids to the museum (their favorite as well as mine), I've noticed that a lot of the exhibits I loved have been replaced by dumbed-down equivalents. Take the original computer exhibit that used to be there; yes it was sponsored by IBM (who provided all the equipment), but that exhibit taught the actual nitty-gritty about how computers work; I can still remember "getting" how binary worked standing there and to a 10 year old geek-wannabe, that was awesome. Now they've got a half-hearted "net" exhibit that is more on "wow" than the specifics of how it works. Did they feel that really trying to explain things would turn people off?

In the SF bay area, there is the Exploratorium in San Francisco, which is kind of like they took the crazy hands-on area of every science museum I've ever seen, and put them all in one place. Just about everything is physically interactive, it's awesome. Then there is The Tech Museum in San Jose, which seems like a lot of displays and button-pushing exhibits - push the buttons in the right order and you'll get a neat printout! But I was terribly disappointed by the entire thing, because it's interactive like clicking things with a mouse is interactive.

So we have a slightly more expensive, rather fragile-looking, patented way to make it possible for people to put batteries in the wrong way.

Great.
I don't want one. I can tell a spring from a contact. It's not too hard even with my eyesight. But a funny hermaphrodite thing as a third option? Now that's confusing.

Well, that's not a problem, just put it in however the heck you want to.

I've always assumed that the springs were used to provide solid contact. In which case this will probably not be as reliable. Realistically, though, I have troubles imagining that expensive devices wouldn't already have a protection circuit, or that inexpensive devices would be willing to pay a licensing charge.

Being able to shed that top 1% can make a big difference.

Which is why I've never quite understood why they want to do it in a "smart" fashion, as opposed to simply giving you a rebate if your appliances are set to tweak their power usage every day during the peak window. The latter would require no elaborate communications system, just dumb timers.

I excitedly got in on the original GIGO scheme, figuring that it would be useful for my young children. The software sucked. I don't mean sucked like it was badly written and crashed a lot. I mean sucked like there was no point to it, it was just a collection of independent geeky tech toys aimed at kids. Some of them were fun, but the package didn't add up to anything nearly as worthwhile as a Leapster.

The hardware is not the right problem to solve. If someone created a comprehensive open-source early-education curriculum, the hardware would magically condense out of the ether. Well, not quite, but you get my point, the missing content means that they are building a solution which is so distant from the problem as to be worthless, except as a PR stunt. The most likely reason this won't happen is because educational curriculum is a terribly hot potato, with lobbies piled nine high on all sides.

While I understand your point of view I also understand the point of view of parents who's kids have actually died from congenital heart defects which show themselves during physical activity.

And you think it's reasonable to expect the gym teacher in a public school to use their access to data to prevent this? I always considered myself lucky (or not) if the gym teacher actually bothered to learn my *name* during the course of the year.

Get to work. Guess why it's called work?

Yes and no. The thing which seems to dig me out of this kind of hole are:

1) Break work down into bite-sized pieces that should take 10-30 minutes, and do one or two of those every morning before checking email or the web.
2) Work less.

#1 is similar to the Getting Things Done system by David Allen. I don't actually follow the system, but the nothing of breaking things down into doable pieces and then doing a couple seems to help. Builds momentum.

#2 is just common sense. If you are spending more time working because you aren't getting enough done, then you'll set off a vicious cycle. Last year I acquired an outside hobby that is somewhat self-limiting (*), and it helps lots. When I'm wasting time at work, that time comes directly out of time I can devote to my hobby. So I waste less time at work, mainly because I can more easily say no to sub-projects which I shouldn't be doing.

+1 to this. A decade ago when I started working at a real company (after a decade as a consultant), I noticed in interviews that a lot of candidates had postgraduate degrees, and they weren't that good. It freaked me out a bit, since I had a B.A. in computer science, and I wondered if that would impact my future prospects?

Turns out, though, that the best way to have a good career is to do something you enjoy, be good at what you do, and work with great people. Those are all somewhat orthogonal to how far you took your education. Do the postgraduate work if it seems likely that you'll be able to do interesting work with interesting people. Go out and get a job if you can do interesting work with interesting people. If none of your options involve interesting work or interesting people, try to figure out why not, because having that network of interesting people is ALL that matters in terms of your future job prospects.

Slight caveat if you're talking about doing your postgraduate work MIT or Stanford or Berkeley or UW Madison or someplace well-known for being awesome in the field. Don't skip that to work at a second-rate company.
