(Bash) Summarize TCP socket states (using netstat)

Tue, 12 Aug 2008 10:08:34 GMT

Filters for tcp and tcp6 lines, so omits udp and unix sockets. Information is gathered from /proc; this uses netstat mainly to format it. Gives output like: 21 tcp LISTEN 12 tcp ESTABLISHED 7 tcp6 LISTEN 1 tcp TIME_WAIT

(Bash) bash lines for simple statistics on SSH break-in attempts

Sat, 02 Aug 2008 12:50:13 GMT

Assumes logs are in /var/log/sshd/* and makes a few text format assumptions that probably make this specific to OpenSSH. Simple, but more than you can see from a quick less.

(CSS) slightly lowered inline icons

Thu, 17 Jul 2008 07:17:28 GMT

Icons placed in text usually look like they jut upwards. A little negative vertical-align will put these images roughly in the ascender-to-descender space. Simple and sort of stupid, but probably still useful to know.

(Python) remove diacritics

Useful when creating canonical forms of strings for indexing.

(Python) Get Home directory path in Python (win, lin, other?)

Thu, 17 Jul 2008 06:48:25 GMT

The current user's home directory is probably the easiest way to get a writeable directory, and expanduser does the sensible thing on various OSes. In case of windows, you can choose to be smarter about *which* directory you pick.

(JavaScript) Javascript add-to-bookmarks (Firefox, IE)

Thu, 17 Jul 2008 06:40:45 GMT

There is no standard for this at all - this just looks for the hooks that exist in IE and gecko-type browsers. See also http://msdn.microsoft.com/en-us/library/ms535926(VS.85).aspx and http://developer.mozilla.org/en/docs/DOM:window.sidebar

(JavaScript) Javascript array member tests

Thu, 17 Jul 2008 06:34:58 GMT

Given: `a=['1',2,6];` Allows things like: ` a.contains(2); //true '1'.in(a); (1).in(a,true); //type not identical, so false (1).in(a); //no type check, so true ` I never actually used this, it was more of an exercise in playing with JS.

(JavaScript) Javascript set(-of-string) functions

Thu, 17 Jul 2008 06:31:03 GMT

Exploits hash keys uniqueness, but in doing so effectively toString()s everything, meaning this should not be used for much beyond strings and perhaps integers. I used this when I wanted to do some client-side filtering of (integer) identifiers.
