For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Finding public writeable things on your linux file system

Wondering what files and directories on your (Unix, Linux, OS X) system are marked "public writeable"?

There should be very few indeed (none is good), but the following will wheedle them out.

find . -perm -2 -print

""Find, under the current directory ('.') all symbols with permission bit "2" set, regardless of other permission bits on that symbol, and print out the path to that symbol""
