Then I could be ready to give up a real computer. And it would be a step towards the paperless office: I could finally review papers (say in PDF) on the computer, as opposed to printing them out and scribbling notes on paper, which is clearly slow and wasteful.
Estimated time of arrival: 2015-2020 for mass-market hardware. If Steve Jobs was still alive and kicking, I'd be expecting Apple to do it.

]]>To save the stickies on OSX Lion, I found an AppleScript script that does that, except it has problems with double quotes in the stickies, so I tweaked it, see below.
One remaining limitation is that it can't handle spaces, so I run the script manually on every space that has some stickies on it - the script creates new files for all the stickies. This also means that if you already saved some stickies and you rerun the script on the same screen, you'll get duplicates. If you know how to fix the access to stickies on all spaces, please let me know.
Here's the script:
set theName to ""
set i to 0
set n to {}
set L to {}
set destFldr to ""
set mydestFldr to ""
if destFldr = "" then
set destFldr to (choose folder with prompt "Choose a destination folder:") as text
set mydestFldr to POSIX path of destFldr
end if
tell application "Stickies"
activate
tell application "System Events"
tell application process "Stickies"
set L to name of windows
try
repeat with awindow in L
set m to value of text area 1 of scroll area 1 of window awindow
set end of n to m
end repeat
end try
repeat with acontent in n
repeat
set i to i + 1
set theName to mydestFldr & "stickies" & "_" & (i as string) & ".txt"
set existsFlag to ""
tell application "Finder" to if exists theName as POSIX file then set existsFlag to "yes"
if (existsFlag = "") then exit repeat
end repeat
try
set theFileReference to open for access theName with write permission
write acontent to theFileReference
close access theFileReference
end try
end repeat
end tell
end tell
tell application "Finder"
activate
open destFldr
end tell

So now, if you were interested in what SAWSDL could be useful for, here's an answer. We are using WSMO-Lite for semantic Web services automation in the project SOA4All, and especially in the SWS registry iServe.
We also apply WSMO-Lite to RESTful Web services - through the microformat hRESTS we structure the HTML documentation that every RESTful API has, and then it's easy to add SAWSDL/WSMO-Lite annotations.
So that's what's been keeping me busy.

]]>XSPARQL is a fusion of SPARQL and XQuery, a query/transformation language able to process RDF and XML data sources and return RDF or XML. It's great for transforming data from XML to RDF or vice versa, and more. Finally the worlds of XML and RDF might be getting closer, yay!
Now go check out the online demo. 8-)

]]>When Adam does something good, such as buying flowers or cleaning the bathroom, Eve can thank him, smile, and it's done, off everybody's mind, a small pleasant memory.
When Adam does something bad, such as forgetting to clean the bathroom or burping loudly, but it's not so bad that Eve would feel like raising it as a criticism (fearing that would be creating a bad feeling), Adam may not notice that it was perceived as bad, and Eve will be left with this unfinished matter on her mind, waiting in the back ready to pop up, souring her mood. When enough of these small unfinished matters accumulate, the last straw (just as insignificant as the others) leads to an outburst of criticism, which focuses on all those small bad things left not-dealt-with, and ignores all the small good things that were closed with a thanks and a smile.
I believe this is a natural course of life — we can't really bring up every small bad thing that someone does.
If the partners keep this natural course of things in mind, it could lessen the violence of the outbursts without keeping any pent-up issues waiting to explode later and with more strength.
This should apply in situations other than couple relationships as well (e.g. in a workplace), but it seemed easiest to describe in terms of two people.
It's not likely to be a new insight, but it's new to me. 8-)

]]>The following seem to be key principles for leveraging RDF-enabled services in an SOA.
- Define interface contracts as though message content is RDF
- Permit custom XML/other serializations as needed
- Provide machine-processable mappings to RDF
- Treat the RDF version as authoritative
- Each data producer supplies a validator for data it creates
- Each data consumer supplies a validator for data it expects
- Choose RDF granularity that makes sense
Apart from suggesting that RDF can be a good internal view on the data exchanged by Web services, with benefits especially in versioning, David suggests that validation has two faces - the producer should say how to validate that the data makes sense, and the consumer should say how to validate that the data is fit for the use by this particular consumer.
Further, David wonders about the mapping between XML and RDF - XSLT seems good enough for lifting from XML to RDF, and SPARQL seems to be a good start for transforming from RDF to XML. I can heartily suggest XSPARQL, a fusion of XQuery and SPARQL, for both mapping directions, but especially for lowering. (I'm a minor coauthor of XSPARQL.)
