Conclusion
We have entered an era of virtually
unlimited storage, enabling the lifetime
store
 To make the store useful we need
annotation, typed links, and database
features
 More capture, more correlation – less work
by the user

Future work
MyLifeBits is:

An experiment in lifetime storage
Digitizing Gordon Bell’s past
 Capturing more of his future


A software system
Capture
 Storage & retrieval
 Organization & annotation

Minimum requirement: fulfill Vannevar
Bush’s 1945 “Memex” vision
Memex
As We May Think, Vannevar Bush, 1945
“A memex is a device in which an individual stores all
his books, records, and communications, and which
is mechanized so that it may be consulted with
exceeding speed and flexibility”
 Full-text search, text & audio annotations, and
hyperlinks
I am data
The guinea pig

Has now scanned virtually all:






Books written (and read when possible)
Personal documents (correspondence including
memos and email, bills, legal documents, papers
written, …)
Photos
Posters, paintings, photo of things (artifacts,
…medals, plaques)
Home movies and videos
CD collection
And, of course, all PC files
Now recording: phone, radio, TV (movies),
web pages… conversations and meetings to
come
Paperless throughout 2002. 12” scanned,
12’ discarded.
Only 44 GB, incl. 10 wma, 14 SQL!!! Video:

The 1 TB Life

1TB gives you 65+ years of:



100 email messages a day (5KB each)
100 web pages day (50KB each)
5 scanned pages a day (100KB each)
1 book every 10 days (1 MB each)
10 photos per day (400 KB JPEG each)
8 hours per day of sound - e.g. telephone,
voice annotations, and meeting recordings (8 Kb/s)
1 new music CD every 10 days (45 min each at 128 Kb/s)
It will take you 5 years to fill up your 80 GB drive
Want video? Buy more cheap drives (1 TB/year lets
you record 4 hours/day of 1.5 Mb/s video)
Trying to fill a terabyte in a year

“yet if the user inserted 5000
pages of material a day it
would take him hundreds of
years to fill the repository, so
that he can be profligate and
enter material freely”
-Vannevar Bush, 1945
So you’ve got it – now what do you
do with it?
Can you find anything?
 Can you organize that many objects?
 Once you find it will you know what it is?
 Once you’ve found it once, could you find
it again?

“A record if it is to be useful … must be
continuously extended, it must be stored,
and above all it must be consulted”
“The difficulty seems to be, not so much that
we publish unduly … but rather that
publication has been extended far beyond
our present ability to make real use of the
record”
- Vannevar Bush

Don't give me a little card
image and say, "That's all
you've got, because that's
what I thought you should
want for your virtual
shoebox." There have got
to be multiple modalities
and the designers have to
be able to deal with that.
… don't metaphor me in,
don't give me only one
way of looking at things.

BONUS SLIDES
Everything goes in a database

You need all the features of a database
(Consistency, Indexing, Pivoting, Queries, Speed/scalability, Backup,
replication)


If you don’t use one, you will find yourself creating
one!
Files as blobs, also sync with file system for legacy

Dear Appy,
How committed are you?
Signed,
Lost and Forgotten Data
By Gordon Bell
http://research.microsoft.com/~gbell
Dear Appy,
I'm having trouble with long-term commitment -- not on my end,
heaven knows, but from the apps that created me and with whom I
like to associate. Over time, these pesky apps evolve and they
simply don't recognize the data that they once helped create! But,
we data progeny -- and there are lots of us -- feel that as our
creators, these apps should be responsible for eternal support.
But the little problem with recognition isn't the worst of it –
sometimes the apps even disappear altogether. I ask you, is it
expecting too much for 20-something year old data like me to be
interpretable by my app (e.g. Acrobat, DB2, Draw, Eudora, Office,
Quicken, or RealNetworks), or am I just associating with
irresponsible apps?
If things continue on their current path, it seems I will be completely
un-interpretable within 20 to 50 years! My apps will move to other
platforms, or evolve to be more Internet- or Next-Big-Thing-centric...
A Storocratic Oath
Do no harm to dates
(File creation, Photo taken)
Do no harm to device created &
other meta-data.
1.
2.
•
Support & aid the creation of critical metadata.
3.
•
•
4.
Camera data & location data are sacred.
When/how the user feels like it
Auto-magically!
Maintain user confidentiality
Classification wish list





Download classifications rather than build them
Definitions & synonyms should help find what I want
Today it is too expensive to manually classify my
scanned paper. E.g. “right time” meta-data is critical!
Next year I hope “the system” can classify papers
and other documents e.g. bills
In 10 years I expect all documents to appear
electronically & classified with a little help from me
Personal Search is not
Professional or Web search
System sees every entry & access
 Everything, not just a professional life
 Limited to SIS, not an infinite amount,
covers a profession & personal life
