In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

http://www.techmeme.com/070812/p1#a070812p1

The two files are index.php (the homepage) and search.php (the search page)

There instructions were first published in debian forum, here `http://forums.debian.net/viewtopic.php?f=16&t=73497` but I added them here for easier access

Add policykit file

Add XML file on the path /usr/share/polkit-1/actions/org.freedesktop.policykit.pkexec.policy with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE policyconfig PUBLIC "-//freedesktop//DTD PolicyKit Policy Configuration 1.0//EN" "http://www.freedesktop.org/standards/PolicyKit/1/policyconfig.dtd">
<policyconfig>
    <action id="org.freedesktop.policykit.pkexec.run-synaptic">

Revision numbers in Git

I come from RCS, where revision numbers are easy to insert into files with RCS keyword strings such as $Revision: $ , $Id: $ and $Header: $ .

There are various posts around of different ways of using revision numbers in Git, e.g. http://stackoverflow.com/questions/4120001/what-is-the-git-equivalent-for-revision-number

When using tags to record release revision numbers, we can use git describe to obtain reasonable-looking revision numbers, e.g. 1.2.1-2-g17880f1, where 1.2.1 is the most recent tag on the current branch, 2 is the number of commits made since the tag, and 17880f1 is the (short) SHA of the current commit (prefixed with g for "git"). These numbers have the benefit of monotonically increasing in the -<number-of-commits>- part, and presumably you would use some sort of meaningful release revision numbers in tags, so they should be fairly easy to understandy by non-technical people (ignoring the -g<SHA> at the end).

Inserting revision numbers in s

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.

Dotted Canonical S-expressions - DCSexps

This is a specification for an s-expression interchange format that attempts to improve upon [2]rivest's canonical s-expressions.

It is an output format for a subset of s-expressions. Those containing only pairs and atoms.

It was designed with the following desirable properties in mind:

It has the canonicity property that (EQUAL? A B) implies the DCS output of A is byte equal to the DCS output of B.
It has the non-escaping property that arbitrary binary blobs can be contained as atoms without any processing. A consequence of this is that dcsexps can be nested easily.
