Searching for an harmonious color scheme starting with a givent color? I recomend Petr Stanícek’s “Color scheme designer“.
Using a simple yet powerfull graphical interface, you can find complementary, triadic analogic and many other methods to any web color. Colors can be directly copied to your CSS.
I recommend combined use with ColorZilla Firefox plugin.
echo get_class($my_class_instance) . '<br/>'; foreach (get_class_methods($my_class_instance) as $method) {echo '--------->' . $method . '<br/>';}
To stock ‘machine readable’ information about a table cell use the abbr tag:
<td abbr="my_data">
Might come in handy for example when you try to give jQuery a handle on specific table cells when id and class tags are already in use.
The ‘abbr’ attribute is an official attribute of the td tag in HTML 4.01/XHTML 1.0 DTD in compliance with S=Strict, T=Transitional, and F=Frameset.
Sometimes, stuff gets stuck in Windows trash. Mouse-click trash emptying doesn’t work any more.
If that happens, use the following DOS code in the command line:
rd /s /q C:\RECYCLERIf something’s really stuck in the recyler, you will get the following error message (or equivalent in your operationg system installation language):
Problem - Le processus ne peut pas accéder au fichier car ce fichier est utilisé par un autre processus
Ignore that message. The trash on the desktop, too, will still have the “full” icon but this wull be gone once you right-point it and ask the trash to be emptied.
Trying to call R from, say Java?
C://Program Files/R/R.exe
returns an error as the Windows command line has trouble interpreting spaces.
Use this call instead:
C://program~1/R/R.exe
The written language, made of letters, words and phrases, is how we mostly do internet search. It doesn’t have be that way though. It is very possible, for example, to search a photograph by drawing its approximation. This is shown by ‘retrievr’, the graphic search engine of System One Labs. In retrievr, you can do exactly this type of non-textual searches. You can also search by uploading an image. ‘Retrievr’ searches for results in the flicr database.
‘Retrievr’ is a python implementation of an image search algorithm originally developed by Chuck Jacobs, Adam Finkelstein and David Salesin at the University of Washington. This algorithm is also implemented in imgSeek is a standalone image management application for UNIX systems (such as Linux or Mac OS/X).
It is interesting to put search engines such as retrievr in context with other non-textual search applications : Shazam, for example, the song recognition service on iPhone and Android. For what we face today is only a biginning of the development of search engines of this type. Projects like these will most probably contribute to the ongloing decline of the importance of text in favour of images and sounds, which has been on its way ever since the advent of television. Step by step, we are entering, perhaps, a post-textual era.
