Five Best Time-Tracking Applications

Best Business Softs 

Klok (All platforms with Adobe AIR, Free)

Built with Adobe AIR, Klok is a lightweight and cross-platform tracking solution. You can create a hierarchy of projects and sub-projects in the task-management sidebar and then track the time spent on each by dragging and dropping them into the workflow for the day. While you can delve into the details of each block of time, simple adjustments like expanding the amount of time you've worked on a project is as easy as grabbing the edge of the block with your mouse and tugging it down.

CheatSheet for Regular Expression

Metacharacters Defined MChar Definition ^ Start of a string. $ End of a string. . Any character (except \n newline) | Alternation. {...} Explicit quantifier notation. [...] Explicit set of characters to match. (...) Logical grouping of part of an expression. * 0 or more of previous expression. + 1 or more of previous expression. ? 0 or 1 of previous expression; also forces minimal matching when an expression might match several strings within a search string. \ Preceding one of the above, it makes it a literal instead of a special character. Preceding a special matching character, see below.

Metacharacter Examples Pattern Sample Matches ^abc abc, abcdefg, abc123, ... abc$ abc, endsinabc, 123abc, ... a.c abc, aac, acc, adc, aec, ... bill|ted ted, bill ab{2}c abbc a[bB]c abc, aBc (abc){2} abcabc ab*c ac, abc, abbc, abbbc, ... ab+c abc, abbc, abbbc, ... ab?c ac, abc a\sc a c

Escaped Char	Description
ordinary characters	Characters other than . $ ^ { [ ( | ) ] } * + ? \ match themselves.
\a	Matches a bell (alarm) \u0007.
\b	Matches a backspace \u0008 if in a []; otherwise matches a word boundary (between \w and \W characters).
\t	Matches a tab \u0009.
\r	Matches a carriage return \u000D.
\v	Matches a vertical tab \u000B.
\f	Matches a form feed \u000C.
\n	Matches a new line \u000A.
\e	Matches an escape \u001B.
\040	Matches an ASCII character as octal (up to three digits); numbers with no leading zero are backreferences if they have only one digit or if they correspond to a capturing group number. (For more information, see Backreferences.) For example, the character \040 represents a space.
\x20	Matches an ASCII character using hexadecimal representation (exactly two digits).
\cC	Matches an ASCII control character; for example \cC is control-C.
\u0020	Matches a Unicode character using a hexadecimal representation (exactly four digits).
\*	When followed by a character that is not recognized as an escaped character, matches that character. For example, \* is the same as \x2A.

Char Class	Description
.	Matches any character except \n. If modified by the Singleline option, a period character matches any character. For more information, see Regular Expression Options.
[aeiou]	Matches any single character included in the specified set of characters.
[^aeiou]	Matches any single character not in the specified set of characters.
[0-9a-fA-F]	Use of a hyphen (–) allows specification of contiguous character ranges.
\p{name}	Matches any character in the named character class specified by {name}. Supported names are Unicode groups and block ranges. For example, Ll, Nd, Z, IsGreek, IsBoxDrawing.
\P{name}	Matches text not included in groups and block ranges specified in {name}.
\w	Matches any word character. Equivalent to the Unicode character categories [\p{Ll}\p{Lu}\p{Lt}\p{Lo}\p{Nd}\p{Pc}]. If ECMAScript-compliant behavior is specified with the ECMAScript option, \w is equivalent to [a-zA-Z_0-9].
\W	Matches any nonword character. Equivalent to the Unicode categories [^\p{Ll}\p{Lu}\p{Lt}\p{Lo}\p{Nd}\p{Pc}]. If ECMAScript-compliant behavior is specified with the ECMAScript option, \W is equivalent to [^a-zA-Z_0-9].
\s	Matches any white-space character. Equivalent to the Unicode character categories [\f\n\r\t\v\x85\p{Z}]. If ECMAScript-compliant behavior is specified with the ECMAScript option, \s is equivalent to [ \f\n\r\t\v].
\S	Matches any non-white-space character. Equivalent to the Unicode character categories [^\f\n\r\t\v\x85\p{Z}]. If ECMAScript-compliant behavior is specified with the ECMAScript option, \S is equivalent to [^ \f\n\r\t\v].
\d	Matches any decimal digit. Equivalent to \p{Nd} for Unicode and [0-9] for non-Unicode, ECMAScript behavior.
\D	Matches any nondigit. Equivalent to \P{Nd} for Unicode and [^0-9] for non-Unicode, ECMAScript behavior.
