Vladimir Lasky gave a very interesting talk about wordpress security at WordCamp Sydney 2012. In it he listed his essential plugins for a secure wordpress site. The plugins are:

removing historical buffer names from the ido buffer list
ido-mode
in emacs has this great feature where it remembers old buffers you have had open in the past and offers then as choices when switching buffer usingC-x b
. The problem is that sometimes it will have names in the list you’d rather it didn’t remember. The solution is easy, simply hitC-k
to instantly kill the entry under point. -
gnus, imap and gnutls in win32
I’ve been trying to get gnus working in emacs in win32 for the past few days. There were a number of obstacles to overcome:
- Install gnutls
- The gnus README.w32 says gnutls should be installed and in the path. I found that it must be in the windows system path to make it work. Setting the path within emacs was not good enough. So add
C:\Program Files (x86)\gnutls\bin;C:\Program Files (x86)\gnutls\lib
to your system path by going toStart/Edit System Environment Variables
then clickEnvironment Variables
and edit Path in System Variables - you need to edit the emacs variable
gnutls-trustfiles
to point to windows paths to .crt files. by default it had paths to unix locations. The only way I could find to get these files was to install cygwin and then makegnutls-trustfiles
equal to("C:/cygwin/usr/ssl/certs/ca-bundle.trust.crt" "C:/cygwin/usr/ssl/certs/ca-bundle.crt")
Unfortunately these last two steps were not obvious to me and it took me quite some time to work through them.
Tip: if you need to debug gnutls, try setting(setq gnutls-log-level 50)
.
Now all I need to do is learn gnus! -
Clickable links in OSX Terminal
For some reason I never thought to search for this before. It turns out, if you CMD+double click on a web link in Terminal.app it opens the link in your browser. Very handy. CMD+Shift+double click for OSs older than Lion.

Converting lines of text into a numbered list in org-mode
Recently I had a list of things in a org buffer that I wanted to turn into a numbered list but couldn’t find an elegant way to do it.
The solution I came up with was to use a regex-replace to insert1.
in front of each line. Then I used org-mode’sC-c C-c
to renumber the lines.
I also asked on #org-mode on irc. Two interesting solutions were suggested.- use string-rectangle
- use org-mode’s org-toggle-item
use the string-rectangle function via the keyboard shortcuts:
C-x r t 1 . <SPC>
string-rectangle is new to me but seems as though it could be very useful. Thanks quicksilver for that suggestion.which is described as:
Insert separator line in table or modify bullet status of line.
Also turns a plain line or a region of lines into list items.
Calls `org-table-insert-hline', `org-toggle-item', or
`org-cycle-list-bullet', depending on context.
The trick is to prefix it with C-u which supplies ARG to the function org-toggle-item which changes each line in a region into an item.
∴C-u C-c -
thenS-right
until you get to the list type you want.
Thanks Thumper_ for that suggestion.UPDATE: zhen pointed me to rectangle-number-lines, which I did look at before but it’s default option numbers the lines without the full stop after each number. As I wanted this for org-mode, I really wanted the numbers to be formatted as “1. “. After reading the help on rectangle-number-lines though, I found that if you prefix it with the argument command
C-u
it will ask you for a starting number and the format of the numbers.
∴ Select a rectangle at least one column wide of the lines you want to number then
C-u C-x r N <ENTER><backspace>.<spc><ENTER>

Delete white space around insertion point in emacs
A while ago I discovered M-\ deletes white space between point and text.
Now I just discovered M-spc replaces tabs and spaces around point with just 1 space.
M-SPC runs the command just-one-space, which is an interactive
compiled Lisp function in `simple.el'.
It is bound to M-SPC.
(just-one-space &optional N)
Delete all spaces and tabs around point, leaving one space (or N spaces).
If N is negative, delete newlines as well. -
openscad is cool
UPDATE: You might also be interested in my list of programmatic CAD tools.
Brendan introduced me to openscad while we were at the hacker space last night. I really like it and I can’t believe I didn’t try this tool out before. You essentially write your solid design in a programming language. Its simple to learn and very easy to get up and running.
There is even a scad-mode for it in emacs which I added to the marmalade repo for easy installation. Anyway here is a screenshot of a display stand I am working on.
