well, copying the messages from ios took absolutely ages ...

10,000 iterations .. folder has 100,000 27byte files  - 0:00:00.765 
seconds
Took awhile to create 100,000 27 byte files.. long after the rebol 
script had finished, the os was still handling the cache...
Size: 2.57mb
Size on Disk: 390 mb
Graham

but we needed 28 byte files to test this out!

I think the results speak volumes.
Graham

and how much space does the db require to store the same data?
Terry

don't know

Does anyone know how to setup a subject filter in gmail?  Can you 
do wild cards like *[Rebol]* for subject filters?

size of DB approx 36 mb.
Took about 6 mins to move the directory.   So it appears to be a 
trade off.
Benefits of using files... 

- much more flexible (ie: a 10mb binary file in a DB is not a good 
idea)
- easier to manipulate.
- magnitude faster access time

the magnitude faster time breaks down pretty quickly when you need 
to retrive a file based on it contents not its title
Terry
23-Jan-2005
[754]
No, my experiments were using the file AND it's contents via SELECT
Tomc
23-Jan-2005
[755x2]
using indexes in your database?
primary key?
Terry
23-Jan-2005
[757]
my DB only had a single row.
Tomc
23-Jan-2005
[758]
that does not answer my question
Terry
23-Jan-2005
[759]
and no, it wasn't indexed :)
Tomc
23-Jan-2005
[760]
there should be an imprivement with any indexing

not only that, MySQL via the protocol couldn't handle the 'rapid 
fire' query rate.
Graham
23-Jan-2005

sure .. doing a DOS attack on mysql://
Terry
23-Jan-2005
[763]
exactly
Tomc
23-Jan-2005
[764x2]
so if you only have one row  what is the difference between athe 
fontents of a given file and its name?
contents
Terry
23-Jan-2005
[766]
the contents of the file, and the row inthe DB were identical.. a 
word °email°, and an email address

relational databases start to be useful when they are given relations 
which typically require more than one column
it is hard to relate apples and oranges if you only have apples
Terry
23-Jan-2005
[769x3]
ahh, but I have relations as well with °7°
in fact, my relations can be spread across the net
so the net becomes on big relational DB.. just without the archaic 
DB system.
Tomc
23-Jan-2005
[772x3]
Im happy for you but to have your test make sense the relation should 
be in the relational database
in the file system the file name is a key and the contents a value
the same in a db would nbe two colums one for the name one for the 
value
Terry
23-Jan-2005
[775]
well, why not run some tests yourself and let us know the results... 
talk is cheap.
Tomc
23-Jan-2005
[776]
the nales and falued are relatted
Terry
23-Jan-2005
[777]
i had two columns in the DB ..
Tomc
23-Jan-2005
[778x3]
in a database you could give a value and return the keys as easly 
as give the keys and return the values
in a filesystem thsi is much less symetric
if one cloum cintained a constant it ought not have been there
Terry
23-Jan-2005
[781]
But the DB uses the filesystem as well?  So in essence, you are skipping 
a step
Tomc
23-Jan-2005
[782]
the db you are using very likely uses "cooked"  storage, but  more 
advanced db use raw disk the filesystem knows nothing od and does 
not touch
Terry
23-Jan-2005
[783]
well, I use MySQL.. pretty much standard these days
Tomc
23-Jan-2005
[784]
I am just starting to use mysql a little bit and it is a great step 
up from plain old flatfiles it is constantly improving  a cinch to 
administer, but limited for complex relations

Hey, I found a really neat GUI interface in the Picasa photo organizer 
program from Google. (http://www.google.com/downloads/) If you download 
it or already have it, just click the "Timeline" button near the 
top of the screen. I think it would be really neat if someone could 
make a REBOL clone of that screen.

It's pretty neat - found pictures I didn't know I had.
Time to delete before the wife sees them!

Subject: [REBOL] Intro to Rebol article for DevX



Hi, i've been asked to write an intro to rebol article for devX, 
a task for

which there are any number of people better suited and for which 
i wouldn't have

the time anyway. So if anyone is interested in writing this i can 
direct the

devx editors to you as i still follow this list well enough to know 
who knows,
even if i hardly ever use the language anymore.

just reading Paul Graham's lastest essay : http://www.paulgraham.com/hs.html

and liking this little bit


Now I know a number of people who do great work, and it's the same 
with all of them. They have little discipline. They're all terrible 
procrastinators and find it almost impossible to make themselves 
do anything they're not interested in. One still hasn't sent out 
his half of the thank-you notes from his wedding, four years ago. 
Another has 26,000 emails in her inbox.

From the article,

The great mathematician G. H. Hardy said he didn't like math in high 
school either. He only took it up because he was better at it than 
the other students.

Isn't Carl the same? He took up computing for the same reasons.
