New form of CAPTCHA

I stumbled upon this tonight.  Seems like it would be a good way of verify humans.  The only problem is having the processing power to generate new ones every time a user views your form.  I’m afraid this will not be practical for many years.  But still, pretty cool

New platform for open data

Factual is a new web application that facilitates the open contributing of data on the internet.  Think of it as wikipedia for databases.  I’m pretty stoked.  I’m not sure if this experiment will turn out to be a winner or not.  But, I sure hope they make it.

The data stored in it is very much open ended.  For example here is a database of one of my favorite things, beer. Go ahead, edit the data. Add whatever details you you want.

Linux-like keyboard mappings for the Mac

This tutorial will fix several non-standard key mappings on the Mac. The fixes are listed below.

  1. Home key behavior
  2. End key behavior
  3. Page Up behavior
  4. Page Down behavior
  5. Cut, Copy, Paste, Undo, Redo, and Save Keyboard shortcuts

First you will need to create a file named ~/KeyBindings/DefaultKeyBinding.dict

On my system the full path name to the file is /Users/jon/Library/KeyBindings/DefaultKeyBinding.dict

If you do not know how to create this file, run the following commands from the console. All commands are case-sensitive!

cd ~
cd Library
mkdir KeyBindings
cd KeyBindings
nano DefaultKeyBinding.dict

Once you have DefaultKeyBindings.dict open in nano, copy & paste the following in it.


{
    /* home */
    "\\UF729"  = "moveToBeginningOfLine:";
    "$\\UF729" = "moveToBeginningOfLineAndModifySelection:";

    /* end */
    "\\UF72B"  = "moveToEndOfLine:";
    "$\\UF72B" = "moveToEndOfLineAndModifySelection:";

    /* page up/down */
    "\\UF72C"  = "pageUp:";
    "\\UF72D"  = "pageDown:";

    /* use the flippin control key */
    "^a"        = "selectAll:";          /* C-a          Select all */
    "^x"        = "cut:";                /* C-x          Cut */
    "^c"        = "copy:";               /* C-c          Copy */
    "^v"        = "paste:";              /* C-v          Paste */
    "^z"        = "undo:";               /* C-z          Undo */
    "^y"        = "redo:";               /* C-y          Redo */
    "^s"        = "save:";               /* C-s          Save */
}

Now, press Control+o to save, then Control+x to exit.

Log out and then log back in for your new settings to appear.

Cheers,
Jonathan

ddate is fun

ddate is a unix utility. It is glorious. Just read the man page.

ddate prints the date in Discordian date format.

If called with no arguments, ddate will get the current system date, convert this to the Discordian date format and print this on the standard
output. Alternatively, a Gregorian date may be specified on the command line, in the form of a numerical day, month and year.

If a format string is specified, the Discordian date will be printed in a format specified by the string. This mechanism works similarly to the format
string mechanism of date(1), only almost completely differently. The fields are:

%A

Full name of the day of the week (i.e., Sweetmorn)

%a

Abbreviated name of the day of the week (i.e., SM)

%B

Full name of the season (i.e., Chaos)

%b

Abbreviated name of the season (i.e., Chs)

%d

Ordinal number of day in season (i.e., 23)

%e

Cardinal number of day in season (i.e., 23rd)

%H

Name of current Holyday, if any

%N

Magic code to prevent rest of format from being printed unless today is a Holyday.

%n

Newline

%t

Tab

%X

Number of days remaining until X-Day. (Not valid if the SubGenius options are not compiled in.)

%{

%}

Used to enclose the part of the string which is to be replaced with the words “St. Tib’s Day” if the current day is St. Tib’s Day.

%.

Try it and see.

Examples

% ddate
Sweetmorn, Bureaucracy 42, 3161 YOLD

% ddate +'Today is %{%A, the %e of %B%}, %Y. %N%nCelebrate %H'
Today is Sweetmorn, the 42nd of Bureaucracy, 3161.

% ddate +"It's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 26 9 1995
It's Prickle-Prickle, the 50th of Bureaucracy, 3161.
Celebrate Bureflux

% ddate +"Today's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 29 2 1996
Today's St. Tib's Day, 3162.

Bugs

ddate(1) will produce undefined behaviour if asked to produce the date for St. Tib’s day and its format string does not contain the St. Tib’s Day
delimiters %{ and %}.

Note

After ‘X-Day’ passed without incident, the Church of the SubGenius declared that it had got the year upside down – X-Day is actually in 8661 AD rather than
1998 AD. Thus, the True X-Day is Cfn 40, 9827.
