Tech guy said if I had setup the first drive on the raid controller, 
it would not be a problem.

maybe a termination problem

hmmm...  That is a strange animal as usually you have to setup the 
correct type of raid and then initialize but I have seen data loss 
doing it

You want to establish the drives as a raid setup but fail the new 
drive and have it rebuilt it

can't change the field.. the tech guy says the card is smart enough 
to know that I have a drive initialised from a diffferent controller.

and it was a mirror before correct?

You might need to backup the data somewhere and rebuilt a complete 
new array and restore

Adding the Controller to an Existing System
In this scenario, you are adding an Adaptec SCSI RAID 2120S/

2200S controller to a system that already has a Windows 2000 or XP
operating system.
To install the driver:
1 Install and configure your controller and hard disk drives
according to the instructions in Chapter 2.
2 Start Windows. Windows launches the Found New Hardware
Wizard, which searches for the controller driver.
3 Insert the driver disk you created at the beginning of this
chapter. Select the disk drive as the source, then click Next..
Since the driver is also on the installation CD, you may wish to
insert the installation CD and have Windows search it for the
driver. Windows will find multiple drivers, select the
appropriate one for the operating system being used.
4 Click Next in the succeeding two windows that appear and
follow the on-screen instructions to complete the controller
installation.
5 Remove the driver disk and restart the system.

You might try from CTRL-A at boot up when the SCSI bios message apears

I can configure the raid card using ctrl-A

Just remember this.  That is usually write a config to the disk itself. 
 This is how it knows what slot or position the drive is even if 
you move them around.  But the NVRAM is on the card and usually backed 
up by battery power to retain the configuration (you need to blow 
that away).

That means it completely using the config of the drive and thats 
why it detects it automatically as a volume.  You most likely wont 
be able to change that then without a special tool from them since 
you would need to force a write to the drive config to show that 
its drive 0 of array 0.

I lost one yesterday too, in the same way.

It all seemed to be working okay for a week or two, but is slipping 
again now.

I'm playing around with mediawiki .. a great little wiki.  Even has 
preferences for your time zone so that you can see when edits were 
done according to your own local reference.

Would be great if such a wiki could be done using Magic.

I've questioned this a few times over the years now.. 

If we have a CGI script that uses the mysql protocol, is it necessary 
to load this protocol with every cgi request?  Wouldn't that add 
some burden to the server?

you probably have a pool of connections which are re-used

forinstance, in Zope, I have a single sql connection which is used 
by all the "cgi" requests.

But if you want to access a mysql server, the cgi script loads each 
time, right?

can you give me an example of a cgi script that access a db, and 
doesn't load the protocol each time?

any Zope cgi script that access a database does that.

if I have a rebol daemon running that has a connection to a odbc 
database, then my rebol cgi script an interact with that.

Well, I wonder what has less overhead.. reading a 23kb protocol with 
each call, or taking the time to do a tcp call?

What is faster, reading a 100 byte text file, or accessing 100 bytes 
from a DB?

after a text file being read from a directory is another db operation.

the filing system is a database

Forced to reduce the number of iterations to 100 for mysql sake.. 
and even then it would choke 50% of the time.. results.. 


Reading the DB used mysql-protocol.r with join mysql://.. localhost 
{select email from table where name='name' }
Reading the file used a: load %file.txt, b: select a 'email
mysql - 1.35 seconds (using time/now/precise

file - 0 seconds (timestart - 18:35:25.531, timefinish - 18:35:25.531)


Conclusion.. no contest.. loading and selecting from file wins hands 
down.

Graham, if i need to wait for a response, then i would need to add 
that time to the total for mysql.

another good point.. think ill load up a directory with a few 100,000 
files and see what happens ;)

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

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

my DB only had a single row.

sure .. doing a DOS attack on mysql://

so if you only have one row  what is the difference between athe 
fontents of a given file and its name?

the contents of the file, and the row inthe DB were identical.. a 
word °email°, and an email address

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

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

But the DB uses the filesystem as well?  So in essence, you are skipping 
a step

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.

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.

I quoted the part above as I too have not managed to get my thank-you 
notes out ... but by a somewhat greater period of time :(

everytime my inbox slows down on account of the number of email inside, 
I just create a new inbox :)

I think a youth hostel is cheapest. But you can check on the net 
easily, I'd say. My place (with three little kids) is too crowded, 
otherwise you could stay here.

In total, the core of our team has invested something like 80 man 
years on this experiment, 18 of which are mine. I think right now 
the key lesson is this -- if you're looking for a job with instant 
and guaranteed success, this isn't it.

on an experiment to measure the winds on Saturn's moon Titan came 
to naught because someone forgot to turn it on

how can we self remove ourself from a private group? it always says 
"you must be included in the group" ???

right, since your in the group, in the first place... but that leaves 
guest on the list after and is not very nice for truely private groups... 
such a thing can go unnoticed by the group's "manager"

I wish there where moderator features in altme... so we could generate 
a moderated group and then you are master of that specific group... 
including removing posts.

graham... that is very wise... your patients must not complain often. 
 You have a very good sense of observation.

that's a 3 frame animation  btw .... ;-)

a mercy

Terry, isnt there a group for that stuff

What, are you the Altme nazi?  If you look a bit higher up this list, 
you'll find your own "out of group" messges.

And regarding the Announce group.. I accidentally made a few posts 
into that group.. I saw that the previous posts had no long term 
relevance, so I cleaned up the whole group.  I'm guessing that's 
somewhat my perogative, given I started the group in the first place.

and its probably a goose step

..villagers who saw it as a divine omen of peace..

 I wonder how villagers that have a history of explosives falling 
 out of the sky see that as a peaceful sign?

perspective... at least this thing from the sky have not injured 
anyone...hence a sign peace'

Animal-Human Hybrids Spark Controversy  --  http://o7o.org/°chimeras°

Scientists have begun blurring the line between human and animal 
by producing chimeras—a hybrid creature that's part human, part animal.


Chinese scientists at the Shanghai Second Medical University in 2003 
successfully fused human cells with rabbit eggs. The embryos were 
reportedly the first human-animal chimeras successfully created. 
They were allowed to develop for several days in a laboratory dish 
before the scientists destroyed the embryos to harvest their stem 
cells.

Damn, a human that can screw like a rabbit!

Anyway, we have had chimeric antibodies used in therapy for a while

Does anyone know if REBOL works on WINPE (Windows pre-installation 
environment)?  If so, is there a way to access the Hard Drive to 
do file recover operations with REBOL?

In case anyone doesn't know what WINPE is - its a tool that large 
enterprises use for image installations/troubleshooting etc..  Very 
similiar to Barts PE which is a free version.  http://www.nu2.nu/pebuilder/

Does someone know xxcopy? That's a very nice tool. I'm searching 
for a clone of it. I need to find out changes between two directories 
A and B. Newer files in A should be copied to C and than all files 
copied from B to A that are different.

I didn't found such a tool. I can make two way syncs but I need just 
to make one way sync and keep the files to-be overwritten if those 
were changed in the last 60 minutes...

With some help from Carl, I got to this:

switch: func [
    "Selects a choice and evaluates the block that follows it."
    [ throw ]
    value "Value to search for."
    cases [block!] "Block of cases to search."
    /default case "Default case if no others are found."
    /all "Evaluate all matches (not just first one)."

    /local code found?

    code: clear [ ]
    while [cases: find cases value] [
        either cases: find next cases block! [
            found?: yes
            append code first cases
            cases: next cases
            unless all [break]
        ] [break]
    ]
    do either found? [code] [case]
]

two local words, but shorter. also, it turns out that using a path 
for system/words/all is slower than using the either inside the while.

I had this (how many ways to skin a cat?):

Ok I looked at the performance from a trace perspective of three 
switch implementations - mine, Gabriels and Chris's.  Out of all 
of them mine was least efficient, while Chris's was the most efficient. 
 So if all of them do what is needed then I would say go with Chris's 
implementation.

what if append was replaced with insert tail? that would make it 
a tiny bit faster

paul, that's a good idea, using trace to do that. wonder if that 
could be wrapped into a counting function that counts the amount 
of trace output?

trace is native. I vote for adding something to trace to make stats 
from the output, perhaps just a single integer that shows how many 
functions were run through.

yeah but it gives you a good idea of what is going on.

hmm.... a bit inflexible, I think. It would be nice to bypass console 
output, and store the output in memory for later scrutiny. this would 
avoid needing to popup a console to an end user.

about trace, if you need a count you can probably just use the STATS 
function.

however, in a trace a call to a slow function will count the same 
as a call to a fast function.

Paul, I don't share your concern about using ALL as a refinement 
of switch. I don't see that "killing the global ALL function" is 
a risk here. We are all aware of the danger of accidentally leaking 
words.

calling switch recursively - hmm, indeed it will be a problem. then 
i prefer chris' version which can avoid the allocation if not needed.

Re. recursive, if you were to make block! [] instead of clear [] 
- I guess it's a difference in resultant garbage: with 'make the 
block becomes unbound when a subsequent switch is called, while with 
clear the cleared values become unbound.

here is a switch that defaults to 'all

It's an issue if you're building a script incrementally and want 
an empty placeholder...

I saw the latest 2.7.2 notes - good job everyone.  Looks like switch 
might be a dead issue for now since the previous changes look like 
they were implemented.

; I guess this is moot, but a slight variation of my prior 'switch:
switch: func [[throw] value cases /default case][
    default: copy [] 
    while [
        all [
            cases: find/tail cases value 
            cases: find cases block!
        ]
    ][case: append default first cases]
    do case
]

unless is a nice addition to standard rebol, I know use it alll the 
time.

Paul, the interim releases are meant as "please test this" by all 
accounts.  IIRC view 1.3 had a few rollback based on user feedback 
of new features wreaking havoc on too many stuff.

anton, do you remember this one:


view layout [text "Push and drag out. The highlight should go away 
when the mouse exits, but it doesn't." tog "Test"]


I remember you talking about that you made a fix for that, which 
didn't work. Do you think we could make a proper fix for View 2.7.x?

Henrik, here's a quick 5-minute patch (not well tested).

I don't really like that hover state anyway. In my style-gallery.r 
I'm aiming to use a similar highlight to indicate the focused state 
of the btn or tog.

perhaps it's a sneaky way of testing R3 code? :-)

but maybe compatibility issue here is not a problem?

Rebolek you make a good point about the switch.  Maybe we should 
modify it so that it can find block! or type? block!  - of course 
it is native right now so I have no idea what that means for the 
code.
