Today I Learned the origin of the "peace sign".

I grew up (here in the States) seeing the peace sign as the ubiquitous symbol of the hippies and anti-war youth (well, I was a child so they were older than I was, but I got it). I did ponder how the peace sign and the two fingered V sign were related as they're opposingly oriented. Oh, I did hear some of the conspiracy theories that the symbol had some sort of satanic origin, but I didn't give them much credit. But until just now, as I was watching a YouTube video, I never knew that it originated with the British Campaign for Nuclear Deterrence and that the symbol is composed of the semaphore signs for N and D.

Here's the video I was watching: http://youtu.be/nmgFG7PUHfo

[edit] replace "deterrence" with "disarmament" above. Oops. smiley - shrug

Thanks for sharing, I didn't know that either. I thought it was meant to be some sort of stylised rocket.

TIL you can erase "permanent" marker with dry erase marker.


It's like magic. Just scribble over the permanent marks with a dry erase pen (I used Expo, I assume similar brands will work, maybe) and then wipe away with a paper towel or whatever. I'm sure there are some caveats, like obviously it won't work on porous materials.


I learned from some random "life hack" on teh interwebs, but yesterday I tried it out for myself. My father's handy man sometimes uses my Ryobi battery chargers to charge his batteries and recently he either confused one of mine for one of his, my largest of course, and when I got it back, it had his initials scribbled on the base. My scratched initial/mark was clearly visible nearby. So, I found this to be a perfect opportunity to try out the Magic Marker hack. And it worked surprisingly well. It completely removed his initials, and did not obscure the product information labeling underneath.

I knew that. Very handy if someone replaces spent white board markers with permanent markers in the conference room (on purpose or by accident)

I'm going to test something right now. I have a dry erase board here in my office. I don't use it often so the markings have become almost permanent and take vigorous scrubbing to erase. Let's see if new ink will remove the old...

Yep!

We used to have a conference room down the hall with a dry erase board with lots of old text visible and seemingly unremovable. We also had a bottle of some solution sold to remove old markings (it didn't). I now wish we still had access to that room, I'd further test this. But alas, it has been converted to storage for the folks in Video upstairs.

Live experimentation, I love that.

I have worked in a white board factory for a whole 1.5 days. If I remember correctly, they used some sort of enamel on sheet metal. If that is still the case it might also be possible to quickly burn off old ink with a blowtorch, but I'm afraid my boss won't let me try that. (apparently there are also cheaper paint based versions)

The white one (likely a plasticized paint on fiberboard) in the old conference room was particularly stubborn for getting old marks off. For that reason I got the plastic coated metal one for my office. I bought it because I was managing 4 separate computers processing lunar mapping film and I needed to keep track of which stage each machine was working on.


(On each computer I had a small toy or stuffy. On the board I drew reasonable sketches of each. Two of them were from a line of stuffed toys called Meanies, satirizing Beanie Babies. I had Flat, the Roadkill Cat, and Bart, the Elephart. I also had a Pinky and the Brain hypnotizer toy, and the last one was a hybrid I created by sticking a Jack-in-the-Box antenna ball on top of a Jar Jar Binks figure. I called it Jar-Jar-in-the-Box, or Jack-Jack-Binks, or Jack-in-the-Binks. I couldn't settle on which was best. smiley - laugh )

That sounds like a good way to distinguish between the computers. Much better than just numbering, especially if you want to put blame somewhere, names work so much better.

After some looking up, I found that enamel (=glass) white boards typically get lifetime performance guarantee, while paint / plastic / other types only get five years, because eventually, they absorb the pigments from the markers and can't be cleaned anymore.
