I'm 34. When I was a kid I won a BBC Model B micro in a competition.
Terrific computer for its day. http://en.wikipedia.org/wiki/BBC_Micro

It was a massive success in Britain and shifted about 1.5 million units.

The vast majority of these had 32KB RAM (there were a few 16KB models, but most were the BBC Model B, the 32K one).

Today, on the back of an envelope (well, MS Calculator), I worked out that all the system RAM of all 1.5 million BBC Micros would most likely fit on three 16GB micro SD cards.

Here's mine:

Some simple multiplication later...

[imath]The\;Internet \approx 500,000,000,000,000,000,000\;Bytes[/imath]
[imath]One\;card = 16,000,000,000\;Bytes[/imath]
[imath]Price\;of\;one\;card = $59.99[/imath]
[imath]Price\;of\;the\;Internet \approx (5 \times 10^{26}) / (1.6 \times 10^{14}) \times 59.99 \approx $21,460,571,386,791,375.33[/imath]

The Internet costs over $21 quadrillion USD to store. That's more than there is in the world, plus it's probably more than Sandisk can manufacture.

Who wants to start up a fund to buy the Internet? I'll start with fifteen cents I have left over from breakfast.

Today, while staring absentmindedly at the recovery disk taped to the side of the proprietary Pentium that runs some specialized hardware, I had an idea.

Hollow out a 3.5" floppy, and store your MicroSD cards in there. It's both functional and ironic.

Heck, I might just do that with my regular SD cards. I only have a few lying around.

^oi alty texty now
I've only had one SD card which was a 128mb, same like I only have a 512mb flash drive, who actually needs more??

I have a 1 TB external harddrive, 640 GB external harddrive, a 320 GB flash drive, a 160 GB harddrive in my netbook, a 80 GB harddrive in my laptop, and a 300 GB harddrive that I will use once I built myself a decent stationary computer. I'd wager that about half, maybe more, of that is filled up with data,..


oh I do have hard drives, I just don't see the point microsds with 16gb space being developed for cameras, if you take that many pictures, somethings wrong with you (unless you're a traveling photographer, valid reasons, etc)
I have three WD 1TB, four Seagate 500GB 7200.11, one WD 500GB "green", one WD 300GB velociraptor

The reason that iTunes and other services are still so stuck on MP3 or ACC is because not everyone has access to a high-speed internet connection. There are a lot of people that only have two options; satellite "broadband" or dial-up. $50 for 512/128 (7.5gb DL limit), $70 for 1024/200 (12gb DL limit), $80 for 1536/256 (17gb DL limit). Pretty expensive, especially when considering how poor the actual connection quality can be, doubly-so from a simple ping time. If you play around with iTunes Plus... 78 minutes of music is about 152MB (The Who; 'Who's Next'). 71.3 minutes of music is about 139MB (G N' R; 'Chinese Democracy'). So yeah, 291MB for 149 minutes. You'd be limited to about 50-60 albums on iTunes, not including your other browsing. MP3 is a necessary evil; I don't like it.

I have already explained why SD cards are not viable floppy replacements. It is for that reason my router is running from a floppy disk instead of a SD card.

The N64 was ace. However It's generally down to how you use it. The 64 could render only half of the polys the Playstation could. But Nintendo used it better. The cartridges could not hold the same data as a CD, but GoldenEye was never beaten on the Playstation.
Oh, and they kept the carts for the DS and the other gameboys. Shows Sony up with their UMD disks.
So do we have Nintendo to thank for all these tiny miniature cards?

It's not a particle or a wave. It's just an exchange.

32GB Micro SD comes out in February.

http://www.engadget.com/2010/01/13/samsung-announces-64gb-movinand-flash-32gb-microsd-card/

once these come out I'm teaming one up with my sansa clip+, 40GB of lossless music including the player in a size smaller than a matchbox...

A note to my fellow American aliens: the British 5p coin is just a hair larger in diameter than a dime* and two hairs thicker.

Dime: 0.705 in. (17.91 mm) diameter, 0.053 in. (1.35 mm) thick
5p: 18 mm diameter, 1.7 mm thick

By the way, the new 5p is uuuuuuugly, forgive me for saying so. The bit of harp showing on the lower left looks more like a kitchen faucet.

Image

* The US 10 cent coin (the smallest current US coin), which is depicted in the foreground of the second panel of the comic. The dime carries the oldest unchanged design of all current US coin denominations, dating from 1946 (with only changes in the location of the mint mark to denote the switch from silver to clad composition and other mint mark changes).

Try the Printifier for xkcd. You can now scale the comic between 50 and 150%.

I find these very useful: Common Errors in English Usage (web site) and Eats, Shoots & Leaves (book). You may, too.

I wonder why that isn't considered counterfeit. Not that someone would bother trying to pass that off as real money. Or are those real coins that have been hallowed out?

Yeah if you look at the product description they're real coinage that's been hollowed. Still not sure of how legit that is but it gets around the counterfeit rules quite nicely.

Also dennisw the new 5p's don't look so bad in person. The shininess definitely helps.

I'd like to see the real chip size of a microsd. The black thing is there so we dont break it.
EDIT: I just found out that the maximum size a microsd (or any SD/MMC) can have is 128 GB. (wikipedia)
Holy crap.

I am going to have to look into MMC (pin compatible with SD cards). At least he initial versions do not have DRM. They also don't have a write-protect tab, but few storage formats do these days.

Edit: temporary and permanent write-protect is supported through software. I would still prefer a physical switch in case the OS is compromised. Samsung MMC Datasheet (pdf)

Today, SanDisk introduced a 128GB microSDXC memory card. What could be stored in a soda can full of those, I wonder? I'd post a link but the forums are flagging it as spam; the news release is the first result for sandisk 128gb in Google.

The thing about recursion problems is that they tend to contain other recursion problems.
