the need for hmac-sha1 (was Re: [partly OT?] Amazon S3, EC2, cyborgs)
Not only Amazon S3 but Blogger and some other web services out there need hmac-sha1 based authentication. Many soap web services need that. Anyone doing web service works on the client side would benefit from having hmac-sha1 support. I'd vote for that. I can't do hmac by hand, but I can do a XSLT subset in about 200 lines! :D Cheers andre On Aug 28, 2006, at 10:53 PM, Dar Scott wrote: On Aug 28, 2006, at 6:46 PM, Andre Garzia wrote: We use OpenSSL for the crypto-thing routines right?

I am just using simple "go to card 1" statements. Card 2 doesn't have any images on it, so there shouldn't be any delay due to that. The only time I notice the delay with the second card is when I run the application as a standalone application. When I am working with the application file (building the application), there is no problem with delays between cards. Also, after I have launched the standalone application and went to card 2, I can go back and forth between card 1 and card 2 without delay. It gives me the impression that all of the cards except card 1 are loading up into memory when I go from card 1 to card 2. I appreciate any more thoughts that you have on this.

Having each of them as separate stack files makes for easy updating, but if they were all part of the same stack file, I would lose that advantage.

That depends on whether you or others using the master library stack would, at times, want to include that as a substack of another stack, say when building a standalone. I have assumed that that is the case in some of my library stacks and thus avoid having substacks of the library stack. I don't really know how others use library stacks. I have stored compressed library stacks in properties. With some tweaking it is possible to use those without saving to disk. This is especially useful for libraries needed rarely, libraries variations that are selected based on the environment, or libraries that must be loaded after an external is installed or put into a temporary location. If a library is used only as a front script or back script, you might consider putting each into a button or other control on a card in your master stack. This might be simpler. (I have a vague impression that stacks as front scripts are slower than buttons as front scripts, but I have not measured that and have no idea why that would be so.) The current darzTimer plugin has versions of the 'darzTimer Helper Library' stacks in properties. Some versions need an external and that external exists where temporary files go momentarily as the library is set up. Right now the darzTimer plugin is much like your master library stack and the helper much like your other library stacks. In the future, after I get some more feedback on how darzTimer is working out for folks, I'll augment it so users can install a 'darzTimer Library' where they want and use that in projects. It would be like your master library and would use the appropriate version of 'darzTimer Helper Library'. In that version, the darzTimer plugin would be simply a client of the 'darzTimer Library'. That library would have no substacks, which--depending on folks' build habits--might be handy. For example, I could make--in that future version--the 'darzTimer Library' a substack of the plugin. If the substacks are very large, then load time might be a factor. However, I don't know of anything inherently wrong with library substacks.

Re: Plugin/Lib Structure
I guess it depends on if the library is for yourself, or others. In the past, I've created an autoinstaller which intalled the requisite stacks into a users main stack. Or, of course you can 'start using' your library as it's own. Another option, and one which I think could be a good idea is 'suck-up/spit-out' where you unpack the stacks in memory when the library is initilized. This has the advantage of being able to work as a substack of a mainstack. -C ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Re: answer files with filter
Upon doing some testing for Mac OS X, if you use the "with filter" clause, you MUST use the file type arguement, and no wild cards characters are allowed in the file type. For example: answer file "choose a file" with filter "F+PR,bob*.prg" -- allows selection of all Foxpro Program files beginning with "bob" and ending in ".prg" answer file "choose a file" with filter "*,bob*.prg" -- no dice answer file "choose a file" with filter ",bob*.prg" -- still no dice answer file "choose a file" with filter "bob*.prg" -- nuh uh. nix. nada. You can see that if you don't know the file type, the "with filter" clause is useless to you. Also note, that on OS X you can SEE the files, but cannot select them if they do not match the filter. Also be aware that the file type IS case sensitive. I think since this seems to work differently between Windows and Mac OSes, you will need to include logic to handle different Oes.

EC2 by itself doesn't offer persistence (the data is gone after the vm quits) so you'd need to move any data you wanted to keep to S3 space. But the pricing is great and it sounds like Amazon is one of the few places around that's really thinking about what Web 3.0 is gonna look like.

Re: Skin conductance measurement
Don't forget that a Bluetooth interface will also give the maximum electrical isolation for the subject!!! (that would actually be my FIRST concern!) Optoisolators or transformers must be used (it's probably a law) between a human subject and anything connected to mains-based devices. That would rule out any DC-scaled sensors (most optoisolators are not linear) unless they're wired into a data acquisition module at the patient end. Old systems probably used PWM for output to get through the isolation. Isolation and safety should be foremost in medical equipment design. (Duh) Me? I don't want to write software that can blow up something, hurt someone or get me sued! ( I guess that also means defense contracts?) Good luck with your new project. Multiply your estimate of how much time it will take by 10, unless you can get out-of-the-box products to do what you want.

I want to allow the user to select a text file, but it has to be a

has to start with "Slot" and have the ".txt".
As has been noted here, filtering for prefixes is a lot harder than
filtering for suffixes. The former is too prone to user error, while
the latter is what the system expects. "Go with the grain", as they say.
Mark Waddingham did an *excellent* reworking of the answer file command
for v2.6.1, and since then it offer unprecedented flexibility which
works on all platforms without branching statements -- from the Dictionary:
Syntax
answer file[s] prompt [with defaultPath] [with type types \
[or type types ...]] [titled windowTitle] [as sheet]
Examples
answer file "Select a file to delete:"
answer files "Select the files you wish to process:"
answer file "Input:" with "/Macintosh HD/"
answer file (field "Prompt") with type "Revolution Stacks|rev|RSTK"
-- shows stacks
answer files "Select the images you wish to view:" with \
type "JPEG Images|jpg|JPEG" \
or type "GIF Images|gif|GIFf" \
or type "All Images|jpg,gif|JPEG,GIFf"
So in your case you could support a suffix like "tsv" and ALSO support
"txt" and all:
answer files "Select a file:" with type "Tab-Separated|tsv|TEXT" \
or type "Text Files|txt|TEXT" \
or type "All Files"
This will present the user on any supported platform with a standard
GetFile dialog with an option control at the top which lets them choose
between filtering for Tab-Separated, Text Files, or All Files, with the
first one ("Tab Separated") as the default.
I LOVE this new "answer file with type" option, and have been replacing
all of my older "answer file" calls with this new form to allow smooth
support on both Mac and Win without having to check the platform and
using "...with filter..." or "...of type..." for each one separately.
Thank you Mark!

function multOffset str,ctr
-- returns a comma-delimited list of all the offsets of str in ctr
put "" into mosList
put 0 into startPoint
repeat
put offset(str,ctr,startPoint) into os
if os = 0 then exit repeat
add os to startPoint
put startPoint & "," after mosList
end repeat
if char -1 of mosList = "," then delete char -1 of mosList
return mosList
end multOffset
function multLineOffset str,ctr
-- returns a comma-delimited list of all the lineOffsets of str in
ctr
put multOffset(str,ctr) into charList
if charList = "0" then return "0"
put the number of items of charList into nbr
put "" into mlo
repeat with n = 1 to nbr
put the number of lines of (char 1 to (item n of charList) of
ctr) & "," after mlo
end repeat
if char -1 of mlo = "," then delete char -1 of mlo
return mlo
end multLineOffset

The following works for me on Rev 2.7.2 on Windows answer file "choose a file" with filter "Slots,slot*.txt" - just shows .txt files beginning with 'slot' (case insensitive) However, the same code using Rev 2.6.1 on Linux does not work - even using with filter "JPG,*.jpg" The whole filter string is inserted into the file selection dialog, matching nothing.

Smooth & Fast Stack Resize?
When I show the default decorations for a stack and resize it with the standard Windows controls, the window adjusts very quickly and smoothly. What I would like to do is to show no decorations and use my own custom controls for resizing the stack window. Unfortunately, the methods I've tried so far result in a very slow, herky-jerky resize of the stack window. Does anyone have a magic handler (that could be attached, for example, to a small rectangle graphic) that resizes the stack window as smoothly (or closely as possible) as the "OS native" resizing method works? ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

This is a more correct suffix for such files than .txt anyway. Since almost nobody actually does this, it would amount, in practice, to a custom file type suffix. In my experience, Microsoft spreadsheets understand this type. OpenOffice however does not, it opens them in Write (doh). So you should test with your preferred spreadsheet. Thanks for the idea Martin, I'll try that and see how it works.
