The floppy hasn’t died — it’s just become virtual

On Of Zen and Computing, Tom Harrison writes about the virtual floppy disk:

Floppy disks have been obsolete for a long time now, but I can see this utility coming in very handy for someone who wants to work with a set of antiquated device drivers, or perhaps relive the good ‘ol days of Commander Keen and The Oregon Trail.

I haven’t missed floppies too badly. Of the three computers in our house, only one has a floppy drive. Still we do have an antique with that capacity. Should we ever need a virtual floppy, I guess we can use it to create one.  And, what with so many manufacturers omitting the drives from computers and so many retailers no longer selling diskettes (did anyone ever call them that?), you’d have to agree that at least the physical floppy is heading for extinction.

Elsewhere on the blog, Harrison explains why the floppy deserves to be dead. Well, for starters:

Floppy Disk capacity is virtually useless

So why do away with floppies? Simply put, their capacity is a joke compared to the size of today’s files and storage mediums. A floppy disk can hold up to 1.44 megabytes of data. Just how small is that?

* The capacity of an 80 minute CD-R is 486 times larger than a floppy disk.
* The capacity of a DVD is over 5000 times larger than a floppy disk.
* The capacity of a 512mb USB drive is over 350 times larger than a floppy disk.
* The capacity of a computer with a 150 gig hard drive is over 100,000 times larger than a floppy disk.

As you can see, you’d need volumes upon volumes of floppy disks to get the same capacity as modern storage devices.

Come to think of it, I can’t remember the last time I used a floppy disk. Give me another decade and I’ll probably have gotten rid of the piles of them on my office shelves…

Drop.io: Free, online file sharing made simple, easy and anonymous

Do you need a simple way to post and share large files on the Web temporarily?

Is sending an attachment over email a bad option, for whatever reason?

You could try Amazon S3 or FileURLs, both of which offer the ability to transfer files around. You could use the tried and true method of posting to a server and FTP client. You could even set up a BitTorrent tranfer between machines.

Or you could check out Drop.io. Launched in November of 2007, this New York City-based storage-as-a-service provider makes storing and sharing files anonymously a breeze. Allen Stern covered the launch of the Drop.io alpha for Center Networks.

You don’t need to register or sign up for an account. Drop.io allows a user to create a “drop” — a dedicated storage space, with all of two clicks. Basic drops are free and include 100MB of storage space.

Here’s how it works:

You creates a drop URL with a unique name more than seven characters long.

You upload a file to it and sets an expiration time (1 day to 1 year) for when it will be deleted, along with passwords for access and administration.

You then can choose what level of access (read, read/write, read/write/delete) any non-admin users will have.

Once you’ve created a drop folder, you can continue to add files and notes to it over the Web, cellphone, email, SMS or even fax.

Each drop also has a dedicated phone extension that allow you to call in and record voice messages that are then added to the drop.

Drop.io isn’t indexed by Google or other search engines, so your data will remain as private as your friends and clients are with the access information.

Drop.io is, in fact, completely anonymous, other than the fact that it tracks your IP address to address legal requirements or tersm of service violations

The service doesn’t require you to give your email address or create a permanent account or profile. Once the drop expires, so does everything related to it.

Just any time you’re uploading large files, there can be freezes or time outs if your upstream connection isn’t all it could be, as David Weinberger noted when he tried it out. I didn’t have any issues when I dropped a screencast for a colleague onto the service.

Drop.io has another cool feature: an RSS feed created for the drop. As a fan of RSS, this is a snazzy feature that instantly opens up new means of collaboration and distribution.

If you post an audio or video file into a drop, bingo: instant podcast, complete with a player. Remember: You can also leave voice messages on a given drop, so this is about as easy a podcasting method as you’ll find.

As Lifehacker pointed out, Drop.io features free, simple faxing. Other folks can send faxes to your dedicated number, where the document are converted into a PDF and syndicated to any portable device that can handle that format. You’ll need to send an automatically generated cover sheet to the sender to ensure proper conversion. Conversely, you can upload a document to Drop.io, enter a destination fax number and click “Fax” to send.

There’s even a way to embed the Drop.io widget in a Web page or wiki, which allows visitors to *send* you files. Password protection is included if you’re leery of malware (an excellent idea, in this writer’s opinion).

Your friends, colleagues and clients can also post to the drop simply by emailing a file to it, though given that the service specifically works *around* sending large files through email servers, this is probably best kept to smaller bits and bytes of content. Just address the message to  yourdropname at drop.io.

Read the Drop.io FAQ for more information or check out the brief tutorial.

Watch a video interview with the founders of Drop.io, Sam Lessin and Darshan Somashekar, from CenterNetworks.
Leo Laporte and Amber MacArthur also had Sam and Darshan on the 46th episode of the Net@Night netcast.
[Listen to the MP3]

The service isn’t perfect: As Dave Winer and Michael Arrington both noted, files posted to Drop.io are not added as an enclosure to the RSS feed, which means you’ll have to go back to the service to retrieve the media.

That being said, I’m an instant fan — and I’m far from alone. The following is just a sample of the positive reviews for drop.io out there:

Download Squad: Share files with Drop.io

AppScout: Drop.io simplifies file sharing and uploading

HackZine: Drop.io is simple, anonymous file sharing

Drape Stakes: Drop.io’s file sharing with RSS = endless possibilities

One Minute Tips: Drop.io is the Swiss Army knife of transfer

What is the missing link of integrated circuitry? The memristor!



Posted by: Alexander Howard

The discovery of Thursday’s Word of the Day, memristor, has been theorized about since 1971, when the possibility for a fourth fundamental passive circuit element was first described. The invention, fully described in a Nature article on memristance, The Missing Memristor Found, has thrown the science of integrated circuitry into a bit of…. flux.

[Image Credit: IEEE's Spectrum]

Ok, terrible electrical engineering joke. Leon Chua (the scientist who first hypothesized about the memristor back in the seventies), as quoted by Margaret Rouse in Overheard in the Blogosphere:

“Electronic theorists have been using the wrong pair of variables all these years–voltage and charge. The missing part of electronic theory was that the fundamental pair of variables is flux and charge. “

Read HP’s Memristor FAQ for more information.

NPR’s Science Friday recorded a terrific show on May 9th on the discovery. From the shownotes:

Introductory classes in electronics are big on circuit diagrams involving different combinations of resistors, capacitors and inductors. Now, researchers say that they have discovered a fourth fundamental passive circuit element, one that complements those well-known three and fills in a gap in the basic equations that describe the relationships between voltage, current, and magnetic flux. The possibility of such a circuit element, known as the ‘memristor,’ was first described in 1971, but until now no one has found a device with the properties of that missing element. A group of scientists at HP Labs found that in nanoscale materials, however, the ‘memristance’ property becomes easier to see.

The find could lead to lower power, instant-on computers, as well as novel types of circuitry. We’ll talk with one of the discoverers of the modern memristor about the find and its potential applications.

Videos: The world’s first holographic storage system and how it works



Posted by: Alexander Howard
Storage, data, video, YouTube, innovation, cool, invention, event, memory

In the first video, Liz Murphy, marketing VP of InPhase Technologies, describes the world’s first commercial holographic storage system at NAB.


InPhase is the company that has spent 8 years developing a practical holographic storage system.

We define a holographic disk drive, the practical implementation of the technology, as “a holographic storage device that uses a laser to store data to optical media in three dimensions, maximizing storage capacity by using the media’s depth. Most optical media, such as CD, DVD, HD-DVD and Blu-ray only offer bit-at-a-time surface or dual-layer writing capacity. A holographic versatile disk is just slightly larger than a DVD and can store 30 times as much data.”

If you want a blast from the past, watch the video below to see Liz Murphy in June of 2007 explaining how HD holographic storage (will) work. She’s interviewed by Scott Jacobs for Futurepeak. (Click ahead to :30 to avoid some shaky handheld camera work.)  There’s a good explanation for how the technology works and some historical perspective on its development later in the video.

Our sister site, Bitpipe.com, just sent me an email informing me that I could view a video of John Cleese offering advice on data distribution systems. (You’ll need to register but, IMHO, it’s worth it. Cleese in a unitard is a sight to behold.)

The video is the next in a series of dependably droll, frequently hilarious spots that follow Cleese’s work as “Dr. Harold Trainwreck” in  The Institute for Backup Trauma  and as the host at the Friendly Advice Machine.

Here’s Dr. Trainwreck on “Rule 26,” wherein he provides advice for corporate counsels and IT managers:

And more of the good doctor, this time providing a (mock) tutorial on how to botch data management.

Sneakernets, removable storage and hassle-free file transfer methods



Posted by: Alexander Howard

One of WhatIs.com’s faithful readers wrote in recently with a suggestion for a much-beloved IT sniglets page (go take a look if you think words like CrackBerry, AlzIMers, IMglish or prairiedogged are a hoot): sneakernet. We love that sort of thing, of course (write to us!) but in this case we already had a definition for sneakernet: a method of transmitting electronic information by personally carrying it
from one place to another on floppy disk or other removable medium. The concepts certainly doesn’t seem many years removed from the days of copying working files onto a 3.5″ floppy disc at the end of the day in the computer room — or even of writing simple algorithms to the cassette tapes attached to the ancient PET computers next to my classroom in the late 80s.

As is so often the case, technology and life comes in cycles. In recent years, the explosion of cheap, removable flash drives (or jump drives, so some folks call them) has allowed mind-bogglingly large sneaker-borne file transfers copied over speedy USB 2.0 ports. iPod owners have long since discovered that those giganormous 80-gigabyte hard drives also make fantastic data warehouses for easy travel and transfer (as long as you don’t forget the cord!) and of course, it’s a cinch for most PC owners to burn a copy of a file to a CD and walk it over to another desk or office. That sort of thing can result in podslurping, of course, as network admins know. Entire operating systems can be carted around as LiveDistros, along with whatever portable applications a user might desire. I won’t even touch, of course, the multitude of flash memory formats that inhabit cameras, smartphones, GPS devices and other electronica, each a potential method of data transfer in “the sneakernet.”

(BTW, hat tip for the cool sneaker image goes to ProZak on Flickr)

So sneakernet is definitely not dead (as noted in this tip from SearchNetworking from 2005). The prompt provided by the reader email did, however, recall to my biological RAM an e-column I read just last week from David Pogue, the witty and frequently funny technology reviewer over at the New York Times. David recently wrote about a trip to California where he managed to forget a folder of 2 GB of digital photos he’d taken of digital SLRs he was reviewing in that week’s paper. With the help of a marvelously patient wife, he managed to get the files transferred over to his laptop from home using a nifty little shareware application called Pando. Pando provides, as David says, “a free, cross-platform, super-simple program designed expressly for idiotproof file transfers, even big ones.”

You can learn more at (you guessed it) Pando.com.

The only snag is that for the service to work, both users have to download and install the client, a step and hitch that David rightly suggests is a potential hindrance, or even impossible for some end users without admin privileges. That being said, Pando worked well for David and is allowing thousands of users to easily backup, transfer, recover and (yes) trade quite large media files. Color me a fan.

Aside from discovering Pando (thanks, David!), the process Pogue worked through is remarkably similar to one that plays out in classrooms and cubicles daily. How to do it? Sneakernet and removable storage is certainly one way, though I hear that the “Interwebs” is an attractive method these days as well. Here’s a crack at a list of ways to make a hypothetical transfer happen. If you have more ideas, please add them in the comments.

For instance, gmail has changed the way that most people think about using email to send attachments, with its remarkably large capacity (convertible to online storage, as I’ve blogged about before, with Gdisk), though I agree with David that 2 gigs is a tag weighty to send this way.

Also like David, I’ve been using FTP for a long time to download and upload files online, though I’ve endured timeouts, unexpected logouts and all manner of file corruptions over the years. I still have fond memories of the early versions of Fetch, including the happy dog icon that accompanied the app. David’s second idea, using an IM-client to transfer files, wasn’t a bad idea at all, though that kind of P2P file sharing isn’t likely to fly on many corporate networks.

As David discovered, however, IM and large files size don’t mix well for file transfer.

Command line geeks know about how to use Secure Shell (referred to as SSH or secsh) to securely access a computer remotely, a method that isn’t exactly for the technically faint of heart but allows direct access to the other computer’s directories. Rajpaul Bagga offers a Secure Shell (SSH) howto if you’re interested.

How else can you transfer large files? The list isn’t short, to be sure, even after touching on CDs, iPods, flash drives, P2P file sharing apps, FTP clients, iPods and IM.

.Mac users can also set up a public folder on their iDisks, which allows them to post large files for others to download, securing them behind password-protection as necessary.

Networking geeks can directly connect one PC to another with a crossover cable. And, as many will point out, a server or shared hard drive can be set up for file sharing as well.

You can use the IrDa port on your PDA and laptop (if they both have one!) to swap files using infrared.

And (of course) Bluetooth can be enabled to allow easy transfer between PCs, PDAs and printers, though bluesnarfing should worry users with proprietary or sensitive data.

Some smartphone users can use MMS to send files as well, most often pictures or (very short) videos taken with digital cameras. Unless you’re on an EV-DO, HSDPA or some other 3G wireless network, however, this won’t work particularly well with larger files.

Did I miss anything? Let me know in the comments!

Gdisk: Turn your Gmail account into a free online hard drive



Posted by: Alexander Howard
Storage, open source, Google

Do you use Google’s Gmail for freemail? Did you know that you can use those 2 GB of free storage space as an online hard disk, similar to Apple’s iDisk? You can enable this functionality in a number of ways.

Gdisk is open source software that turns your Gmail into an easily accessible online storage vault. Gdisk can be downloaded for free from SourceForge.net — but only for Mac users.

Have no fear! Gmail Drive offers similar functionality for Windows users.
