Barcodes: The Number of the Beast
Boomzilla continues: Barcodes were first developed in the railroad business to keep track of which cars went with which engine. The barcodes were imprinted on the side of the railway cars. The barcodes on each car could then be read together to compile information on that particular grouping; what station they came from, where they were headed, etc. thus automating the process of marshalling. When the business world realized how well this system worked, these railway barcodes evolved into the UPC system with which we are all familiar. To really be able to take in the wonder that are bar codes, check out the excellent FAQ created by Russ Adams and an article from the BBC.
Coming full circle, the clever folks at Bekonscot Model Railway in the UK have utilized barcodes at every turn of their expansive system. For example, an MP3 player is driven off barcodes attached to trains. The trains are announced before they arrive and when they are leaving, stating their destination, route and at what stations they will call.
Want a barcode of your name?
What about all those games that came out a year or so ago with commercials exhorting kids to run around grocery stores ripping things off of shelves in an attempt to "power up" their videogame creatures? Those were cool...er...stupid.
I got a big tattoo of my SSN in barcode format right on my forehead.
That way people know who I am.
It is unclear from any of those links if this makes me cool or not.
There are some odd things afoot now, in the Villa Straylight.
The use on train cars was not without problems. Some roads ran the cars through a sprayer before trying to read the codes. Union Switch & Signal installed competing systems that used inductive loops; obviously more expensive but high reliability.
Glad to see those things got a use past Mail in rebates. Never did like sending in those UPCs though, seems like a huge hassle for a little picture of a bunch of bars. Why can't they just be like removeable stamps that you just tape to the envelope or something? oh well, so much for my troll. btw, nice artwork.

Barcodes: The Number of the Beast
It never occurred to me that Satan might be living in my UPC symbols. Now I need a priest to accompany me to the grocery store.
The coolest voice ever.
This reminds me of a recent escapade that my good friend Julius and I recently blundered through. Our favorite magazine is "Club", a prestigious journalistic wonderworld of intelligence and quality. We decided to have the barcode for that magizine tatoo'd onto our male members. Painful, yet oddly spiritual.
Standard UPC bar codes consist of a set of lines to mark the start of the code, the left hand part of the code itself, another set of marker lines, the right hand part of the code itself, and a third set of marker lines:The marker lines are "0101", "01010" and "1010" respectively, where 0 is white and 1 is black.
Now, the encoding scheme is complicated, but it just so happens that "0101" if treated as data on the left hand side would decode to the digit "6".
Similarly, "1010" on the right hand side would decode to a "6" if it were data. The middle also has a "1010" or a "0101" depending upon how you want to look at it.
Hence every UPC bar code has "6...6...6" built into it.
There are some technical niggles with the theory. The middle marker has that extra white bar on the left, but this can be explained away by saying that a gap is needed before the next coded part starts, or that it is to make the thing scan both ways. Yup, it even reads "666" if you play it backwards.
In "The Master of Space and Time" Rudy Rucker jokes about this theory by having an alternate universe where people pay for their groceries by having the checkout operator swipe a UPC code that's tattooed on their foreheads.
How did I ever go on in life without know this stuff?
I'm trying to replace my useless trivia knowledge with something more worthy of knowing. This isn't helping...
So, seriously, what's up with the barcode expose? Is it that slow of a news day?
Good quote, too many chars. Seriously, the slashdot 120 char limit sucks!
The 666 bugaboo has been attributed to so many different things, it's impossible for anyone to take it seriously. The pope, Ronal Regan, barcodes, socal security numbers, driver's licenses, you name it.
Does anyone remember the game barcode battlers??? You used bar codes from anything you could find and swipe them through a reader and they would give you stats for your character to fight other characters. Really neat idea. Ahh early 90's technology... hehe.
So exactly what does that bar code on the back on my neck mean? I had it scanned at the grocery store, it seems I'm cheap and can be bought for $6.66

what does it mean for a person to be able to read and write in user group world, without being able to execute?
rw-rw-rw-!
The 666 rumor comes about from illiterate, non-mathematical conspiracy theorists.. On a barcode, the black bars represent 1 and white bars represent 0. Most of us, I hope, understand that. When the barcode scanner reads the barcode, it must know when to start reading and stop reading, and it does this by finding the code "101" you see at the beginning and end of the barcode. Also, in the middle of every UPC is a 01010 combination, which basically tells the scanner that it has reached the middle of the barcode. The beginning, middle, and end lines are longer than the rest, and some people think that these longer lines represent the number 666. Actually, 101 in binary is 5, so if you are that paranoid and into conspiracy theories, the longs lines on the barcode read "555"

Did anyone else read that as Andy Dick? I thought the only things andy dick did was get naked and fall down a lot.
I can't all your questions but I can tell you unequivicolly that many UPCs in the U.S. are not unique. I worked for a while as a pricing analyst for Safeway food and drug. Dealing with duplicate UPCs was a problem.
As I understand it-- there is a newer standard with longer barcodes and europe has moved to it but the u.s. still uses the older UPCs.
It's hard to believe that's how Micronians are made. Why don't we see it right now by having you both kiss one another?
Even cooler than barcodes is RFID. You don't even have to aim to get it to scan correctly. The only problem is the printers that you let you arbitrarily mark the tags are expensive; about $1000, whereas barcodes can be printed on anything with black ink.
BUT!!... optical scanners are expenive ($250 and up). Yet you can get a RFID USB reader for about $60. It comes with a few premade tags. You can buy pre-signed RFID tags for less than $1.00 each, and a sheet of them can usually be run through a printer; then you could have barcodes AND RFID.
We're considering using such a system to do inventory control. Fun!

And Now For Something Completely Different: The definitive book on barcoding is "The Bar Code Book" by Roger C. Palmer (4th ed., (c) 2001 Helmers Publ., Inc., ISBN 0-911261-13-3). How do I know so much about barcodes? Trust me - you don't want to know.

So you get to the checkout with your self install kitchen. A little old 97 year old lady has now got to try and
a) locate the barcode on each item of your self-install kitchen, containing many items that are several orders of magnitude BIGGER THAN SHE IS.
b) having located the barcode, get her scanner to it.
O.k. - I never thought I'd find a forum where this story might even have the slightest relevance but here we are.
For a few years I worked for Safeway Food and Drug as a File Maintenance Clerk. I printed pricing labels and hung them on the shelves. I made price signs, applied the batches to change prices, etc.
Safeway has a system in place on the registers where certain activities require a manager with an override card. Checks of a certain amount, large voids, all kinds of stuff.
Since I worked on the computers all the time I was the one who changed the message on the bottom of receipt tapes- with the manager name- when we got a new manager. One day I'm moving around in the file that contained that information and I find all these long numbers in one location. They were all the managers override numbers.
Here's where the barcode part comes in. I wanted my own over ride card. I went into the software I used to print price labels and took a single record and changed the UPC of a product on the label to an override number. When I printed the label- the barcode in the corner for ordering now read the override number.
I cut the barcode part out, peeled the back and stuck it to a card I carried in my wallet. Now any time I needed an override I could just scan that card over the register scanner.
On a side note- I called company security and told them that all the manager codes were in plain text where anyone could see them in the machine. They told me it was o.k. because noone would ever look there. Kind of funny. It is probably still that way.
It's hard to believe that's how Micronians are made. Why don't we see it right now by having you both kiss one another?
It is, of course, Abbey Road not Abby Road and they are alive and well and still playing games with the famous photo (and have a webcam pointed at the zebra crossing so you too can see loads of tourists getting nearly run over while trying to re-create that photo). Plenty of geek technology there too, for anyone who's into serious playing around with analog and digital sound recording and manipulation.
Disclaimer: I do have links with people there, and yes it is a nice place to hang out (it's still the best place to record the soundtrack for big movies such as Star Wars, LoTR, etc).

You know, I'm completely fed up with shit getting dressed up as art. Paint thrown at a canvas- it's just paint, thrown at a canvas. A bathroom sink, dragged out of a dump, is just a effin' sink, dragged out of a dump. I've seen both gussied up as "art", and it's not- it's a no-good, washed out artist, who couldn't think up something creative, got desperate to put the meal on the table...so they went "random", and dressed it up as creative; someone was stupid enough to fall for it(or they're hero-worshipping), and everyone else outright pretends, or convinces themselves to see something in it, all because they don't want to feel stupid. Random is not creative. Random is not unique, in the sense of unique = valuable; it's just unique.
Streaming the entire works of Shakespear as barcodes is just streaming the text of a book as a barcode. It has no creativity; it adds nothing to the original work; it serves no purpose; it cannot be appreciated or celebrated, and there would be no difference between using Shakespear or the latest copy of TPenthouse, as far as any observer could tell.

According to most slashdot posters: MSFT
That's gotta fit into your schema somewhere
No it wouldn't.
Now, the encoding scheme is complicated, but it just so happens that "0101" if treated as data on the left hand side would decode to the digit "6".
It appears that the encoding is Gray Code, where successive numbers only differ by one bit.
Hence:
0000 = 0
0001 = 1
0011 = 2
0010 = 3
0110 = 4
0111 = 5
0101 = 6
European barcodes are indeed different from US ones. For example, US records will have a 12-digit UPC number, whereas European records will frequently have a a 13-digit EAN code. You can actually get several different length codes within both UPC (American) and EAN (European) systems. See e-centre for more info on EAN codes. Of course, this does mean that only American products contain the number of the beast. Make of that what you will.
My title to the post makes me think of shamen. Shamen throw bones to tell fortunes and future events. In the Bible they cast urem and thumen to determine selection of elders and clerics. I wonder if either of those are TRUELY read like barcodes or whether Shamen and Biblical figures made things up to suit the task at hand or the situation.
I had turned my name into a barcode a long time ago after watching THX 1138. They all had barcodes on them that told their names. I have my barcode printed onto a laminated card in my wallet. If I can think of it, I scan it in different stores. If read by a Walmart Barcode scanner I am a bouncy ball from the toy department 99cents.

This site has an interesting article that fully explains how classic barcodes work, how you can decode the bars, etc. An interesting read.

I actually do have a buddy who had his SSN in barcode format tattooed on the back of his neck (as a comment on privacy erosion, etc.), about 10 years ago... I think we were still in high school.
I just went to his wedding last year. Forgot to ask the bride what she thought of it, though.
There are only 10 types of people: those who understand decimal, those who don't, and, uh, 8 other types I forget.
There are loads of cars in the UK these days with 666 in the registration. I should point out, for non-UKians, that UK car registrations used to run , then switched to . It's changed again though. Incidentally, you will never see the three-letter group "BAS" on a UK number plate - because the "AS" part means "Inverness-shire", where people speak Gaelic. And "bas" in Gaelic (actually should have an accent over the "a") means "die".
Why was the price included as part of the barcode? I thought that the idea of a barcode was to contain a unique identifier that could be matched up with an item in the Stores database to get the price and inventory information. As I understand it the recode issue involved people printing their own fake barcodes with a reduced price and then using them to buy stuff in stores. I don't understand how this could have worked when the item price should not be a part of the barcode itself. Unless they were swapping the code on one item with one from a similar but cheaper product. But you hardly need to use a website to do that!
