ftff, ftwhich and whichman are fault tolerant search
utilities. whichman allows to search for man pages that
match approximately the specified search key. ftff is a
fault tolerant file find utility and ftwhich is a fault
tolerant version for the 'which' command. The error
tolerant approximate string match is based on the
Levenshtein Distance between two strings. This is a
measure for the number of replacements, insertions and
deletions that are necessary to transform string A into
string B.
ethwireck can detect if the physical layer of the
Ethernet is up. This can then be used in the init script
for your network card to determine whether or not an
interface should be brought up. You can branch then
and bring e.g the cooper ethernet interface up if a wire is
plugged in otherwise use wlan.
ethwireck implements basically the link state of
ethtool and mii-tool in one program.
# this is how you can use ethwireck: if ethwireck eth0; then echo "eth0: physical layer up ..." else echo "eth0: no wire plugged" return 1 fiethwireck may not work with all network cards. It depends on the driver. You have to try if it works on your PC
Unicode::UTF8simple provides UTF-8 conversion for perl versions from 5.00 and up. It was
mainly written for use with perl 5.00 to 5.6.0 because those perl versions do not support Unicode::MapUTF8 or Encode.
Unicode::UTF8simple is written in plain perl (no C code) and will work
with any Perl 5 version. It is just slightly slower than Encode.
In the CPAN perl archive UTF8simple is available at:
http://cpan.org/authors/id/G/GU/GUS/
This application allows you to consistently name files taken with
different cameras. It makes sorting and archiving very easy.
It is basically the same as the below exiftimestamp but it is written in
C++ instead of perl. It is much easier to install because it has
no dependency other than standard libraries and itself.
It runs under Linux, Mac and Windows.
If you are using Windows and you are afraid of the command line then just go to your filemanager. It's drag and drop from within the graphical user interface of the filemanager:
[画像:[using exifdate under windows]]
p0444.jpg -> 2014年04月19日_1240-444.jpg
p0445.jpg -> 2014年04月19日_1240-445.jpg
...
exiftimestamp is a little command line utility to rename jpg camera image files by using the exif date information inside the image.
exiftimestamp works unchanged on Linux and Mac. Windows users should
take a look at the above exifdate application which can be used with
"drag-and-drop" from the file manager.
--------------------------------------------------------- USAGE: exiftimestamp [-h] filename1.jpg filename2.jpg ... or let the shell do the work: USAGE: exiftimestamp *.jpg OPTIONS: -h this help exiftimestamp is very useful for sorting and archiving your various digital images. The file names are constructed such that they sort automatically by time. The date/time information is read out of the image exif data. The new filename will look like this: year-month-date_time-3digitserial.jpg Example: 2013年05月31日_1710-668.jpg The 3digitserial are the last 3 digits of the serial number that the camera assigns to the image e.g pict04668.jpg ---------------------------------------------------------
HTML::TagReader is a perl extension module which
allows you to read html/xml files by tag. That is: in a
similar way as you can read textfiles by line with
"while(<>)" you use HTML::TagReader::getbytoken to
read a file by tag.
[HTML::TagReader Logo]
The HTML::TagReader package contains some applicaition
programs which are very useful for web-masters. All
programs start with the prefix "tr_" to make it easier to
remember their names.
tr_blck is a utility to check for broken links in
web-pages. blck is very fast and checks only relative
links but together with tr_httpcheck it can also
check for dead absolute links of protocol type http/https.
tr_httpcheck is a perl script that checks for the
existence of a web-page by issuing a GET request to the
web-server.
tr_llnk is a utility to build tar archives from a
number of html pages. It helps you to include all images,
textfiles etc.. into the tar archive. It can also be used
to list all linke included in a html page.
tr_xlnk can process html files and expand links
on directories. This is useful if you want to click
through html files without a web-server.
tr_mvlnk modify links in html files with perl
commands
tr_staticssi expand SSI directives #include
virtual and #exec cmd
tr_tagcontentgrep grep for strings inside tags only.
tr_delfont delete font tags that hardcode the
size or font face
tr_imgaddsize add width and height to <img
src=...>
In the CPAN perl archive HTML-TagReader is available at:
http://cpan.org/authors/id/G/GU/GUS/
The cpan.org documentation tree used to contain a very
good Perl Quick Reference Guide written by Johan Vromans.
This this small booklet is now also available as a Pocket
Reference from O'Reilly ("http://www.ora.com). Since the
move of documentation out of the cpan.org directory tree
this Quick Reference Guide is no longer part of the perl
documentation.
I provide it therefore here for download. In addition you
find also links to a HTML version made by Rex Swain
(originally from http://www.rexswain.com/perl5.html) and
a pdf version.
lfwmail is a light weight web mail program written in
perl. It will run with acceptable speed even on a Pentium
100Mhz Linux mailserver. It has just basic features and
no calendar or folders but it is fully mime compatible
and can handle attachments.
The code is clean and structured. The installation is
straight forward and you don't need a lot of non standard
modules.
Note:webgrep will not be developed further. It
is now replaced by Tagreader (see above).
webgrep is a set of small programs for the web-master.
blnkcheck is a utility to check for broken links
in web-pages. blnkcheck is very fast and checks only
relative links but together with httpcheck it can
also check for dead absolute links of protocol type http.
httpcheck is a perl script that checks for the existence
of a web-page by issuing a HEAD request to the
web-server. httpcheck can also do requests via a proxy
server. srcgrep is quite useful to quickly check
which images are included in a web-page and to see where
they come from. It searches for the <... src="..." or
< ... background="..." in a web page. hrefgrep
works basically like srcgrep except that it searches for
< ... href=...>. taggrep is a generic grep
utility to search for a given html tag. E.g to list the
document title of a number of web-pages. webfgrep
is a poor man's web search engine. lshtmlref is a
utility to build tar archives from a number of html
pages. It helps you to include all images, textfiles
etc.. into the tar archive.

Bitbang mode is a special mode of the ftdi serial IO chips
which allows you to use all 8 IO-pins either as input or
output.
You can query the state of each pin at any time (function ftdibb_getBitMode)
An output pin can be set to 1 (=+5V) or 0 (=0V). It will stay in this
state until you change it again.
This is a simple and easy to use library for linux. Examples are
included.
This is a software only sine wave generator. It uses
the sound card of your linux computer to generate any
sine wave between 50Hz and 5kHz. It is based on a piece
of example code from alsa-lib.

A real server machine does normally not need any
keyboard, monitor or mouse. It needs a good operating
system, like Linux, and a network card. External devices
like mouse and keyboard disturb only. With Linux running
on the machine, remote administration is the best and
most convenient solution. However sometimes you would
like to have a little button to properly shutdown the
server: sled is the solution.
sled is the driver software for a little push button to
connect to your server on the serial line. You can use it
to shut the machine down when needed. It has as well 2
LEDs to monitor the state of the server.
plhtml is a preprocessor for html documents. Its
purpose is to simplify the work of writing large numbers
of HTML documents. It acts like a compiler, i.e. you
provide an input source text and plhtml produces the HTML
documents. Unlike many other programs of this type plhtml
does actually report the line number in the html input
file if it comes across a syntax error. This makes it
very easy to find faults.
Modern cdrom drives are too fast. It can take several
seconds on a 60x speed cdrom drive to spin it up and read
data from the drive. The result is that these drives are
just a lot slower than a 8x or 24x drive. This is
especially true if you are only occasionally (e.g every 5
seconds) reading a small file. This utility limits the
speed, makes the drive less noisy and the access time
faster. cdspeed is also very good if you prefer to listen
to the musik on your mp3 CDs rather than the noise of
your CD drive.
Note: recent versions of the eject command include the
functionallity of cdspeed (via the -x option).

This is a simple script based on http://xa.bi/mms/.
To use it do the following:
gpppwrap is a graphical user interface to conveniently
select a phone number and dial into your ISP. It's very
convenient if you use different ISPs.
gpppwrap is only a wrapper around the ppp-on/ppp-off
scripts and gives you therefore still the power and
flexibility of these scripts. gpppwrap uses
ppp-on/ppp-off perl scripts which are Set-UID root to
give ordinary users the possibility to setup a ppp
connection to the selected phone number. gpppwrap is
based on the gtk GUI libraries.
gpppwrap is written for people who like the power and
flexibility of shell and perl scripts and want at the
same time an idiot proof way to connet to the internet
when grandmother is using the computer.
From version 0.6 on a cgi-script called pppcontrol is
included in the package. It provides the functionallity
as gpppwrap and can run on a local webserver.
This package contains ready configured real "internet by
call" ISPs for Germany. You can use them if you are in
Germany. You just pay via your normal phone bill. No
prior registration needed.
Please let me know if you have such "internet by
call" ISPs also in other countries. I would like to add
them.
This is a really nice pre-school/part time daycare on Montreal's West-Island.
Beaurepaire Preschool or "Beaurepaire Nursery Group" (BNG) is a community and volunteer supported pre-school for children from 2 to 5 years old. Everybody has only positive things to say about this small daycare.
I can really recommend BNG (that's why I put it here).

Here is a picture from our wedding (16 July 1999). More information about my wife can be found on her homepage.
This is a collection of some Shell and Perl scripts.
The scripts are most of the time plain text
files. Therefore DO NOT try to download them under
Windows. Windows will change the character set and some
scripts will not work any longer:
include "/usr/share/themes/Emacs/gtk-2.0-key/gtkrc" gtk-key-theme-name = "Emacs"
I have this old map of Montreal (does not have a date but it must have been drawn between 1750 and 1800 based on the details shown). It is possible that this is a copy of another more original map but it is not a modern re-print. It might be of scientific and historical interest to other
people. Click on the map to get a more detailed view.
