QOTW: "Drat that uncertain organic memory."
-- William F. Adams
"It is a M$ world, text tag bindings fire at current, which is mouse, not at
insert, which is keyboard [...] because happy people don't use keyboards."
POTW: Car Racing in Tcl by Richard Suchenwirth.
All of Richard Suchenwirth's "weekend projects" are amazing, but this
one is *so* amazing that there is suspicion of infernal collaboration!
Easily the biggest news of the month: XOTcl's in the core! Watch
for more details, and, in the meantime, send thanks to Jeff Hobbs.
You want to wrap your secret Tcl code to hide it from prying eyes,
but someone else is just as determined to unwrap your secrets:
Standalone Tcl/Tk apps are done a little differently on Max OS X:
[socket -async] can appear to block for a while when it has to
convert an unreachable hostname into an IP address:
Tips on accessing a database using a pool of connections:
It sure seems like "." and ".." are always first in
[glob -types hidden *] on unix, but is it guaranteed?
Thanks to Arjen Markus for his report from the Wiki:
The summer on the northern hemisphere is nearing its end - certainly
in the low lands by the sea that form the home of your chronicler.
So, the holidays are over and the time has come to summarise the
We start with a colourful toy, <http://wiki.tcl.tk/12202>>. It is
based on the more serious colour wheel, <http://wiki.tcl.tk/12201>>,
but it is a toy for the very young.
Next a few pages that deal with resources of some kind:
- Enforce quota via a virtual file system - <http://wiki.tcl.tk/12087>>
- Why is port 0 not available for sockets? A glimpse of the problems
is to be found on <http://wiki.tcl.tk/2230>>
- If you can read French and are looking for an example of how to
work with the Metakit database system, try <http://wfr.tcl.tk/722>>
- Another French page, a simple enquiry about the two Wikis - what
pages were updated? <http://wfr.tcl.tk/721>>
- A brute force approach to programming: given the input and the
output what program satisfies this combination. With a lot
of patience the script at <http://wiki.tcl.tk/12199>> comes up
with a solution.
- Another shot at functional programming: make new (mathematical)
functions without making new procedures. <http://wiki.tcl.tk/12208>>
shows the principle.
And the last category: techniques
- Fourier analysis is a powerful technique for dealing with any
periodic signal. Try <http://wiki.tcl.tk/12183>> as one of
a series of pages devoted to the subject.
- You can sort lists of data with all kinds of algorithms. Here is
a page that puts them together - <http://wiki.tcl.tk/12174>>
- I did not know them, but skiplists might be just what you need
instead of a balanced tree of data ... <http://wiki.tcl.tk/8895>>
