(Bash) Summarize TCP socket states (using netstat) - scarfboy

Tue, 12 Aug 2008 10:08:34 UTC

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 - scarfboy

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 - scarfboy

Thu, 17 Jul 2008 07:17:28 UTC

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 - scarfboy

Useful when creating canonical forms of strings for indexing.

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

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) - scarfboy

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 - scarfboy

Thu, 17 Jul 2008 06:34:58 UTC

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 - scarfboy

Thu, 17 Jul 2008 06:31:03 UTC

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.
