Ruby code to do a buffered file write. Writes chunks of a file to disk from a form post. Ala Johan Sørensen.

File.open("", "wb") do |f|
  while buff = file_field.read(4096)
    f.write(buff)

Ocassionally things go bad(tm). This has bit me for the second time in approx 3 years now, but generally one needs to load the old FreeBSD kernel to start debugging and going through a box with a fine toothcomb.

The following snipbit gives you an idea what steps to take when rebooting the server so that you can load the previous working copy of the FreeBSD kernel:
When the boot menu appears hit the spacebar to stop the countdown.
Press "6" for "to escape to loader prompt"
unload
load /boot/kernel.old/kernel
boot

Now the old working FreeBSD kerenl is booting up. It would be recommended to copy the last working version to /boot/kernel.last for example so that you can "load /boot/kernel.last/kernel", especially if you are going to be building your kernel multiple times on a server.

Quite useful for mobile users who work at different locations and require different proxy server settings for each location, just point your Automatic Proxy Configuration URL to your local proxy.pac file and it automatically pics up if it should use a proxy server or not.

function FindProxyForURL(url, host)
{
   if (isPlainHostName(host) ||
       dnsDomainIs(host, ".foobar"))
       return "DIRECT";
    else
        if (isInNet(myIpAddress(), "192.168.99.0", "255.255.0.0"))
            return "PROXY 192.168.99.2:3128; DIRECT";
        else
            return "DIRECT";
}

If you need to easily retrieve a x509 certificate from a remote webserver, the easiest method is:

openssl s_client -showcerts -connect www.example.com:443

Which you can then go and copy from the line starting with '-----BEGIN CERTIFICATE-----' to '-----END CERTIFICATE-----' into the www.example.com.crt file.

Occassionaly you have a internal mailserver on a machine which has a hostname like machine.example but for mail purposes your machine is known to the outside world as mail.example.com one can use the following helo_data on in your transports for exim to announce yourself as mail.example.com:

remote_smtp:
  driver = smtp
  helo_data = mail.example.com

User the "begin routers" section add:

route_append:
    driver = manualroute
    domains = *
    transport = remote_smtp
    route_data = "smarthost.host.name byname"

For some odd reason tortoise SVN loves to commit empty commit sets. So I managed to get the following pre-commit script working under FreeBSD, seeing that the pre-commit.tmpl does not work as expected.

#!/usr/local/bin/python
"""
Subversion pre-commit hook which currently checks that the commit contains
a commit message to avoid commiting empty changesets which tortoisesvn seems
to have a habbit of committing.

Based on http://svn.collab.net/repos/svn/branches/1.2.x/contrib/hook-scripts/commit-block-joke.py
and hooks/pre-commit.tmpl
