Specifically Twitter has said that they will only used these assigned patent rights defensively to protect themselves against hostile actions. And further that any company that acquires these patent rights from Twitter will need the inventor’s consent to use them in an offensive action. Twitter has also provided the inventor with certain rights to license the patent to others for defensive purposes. You can read the entire set of provisions on GitHub.

Changing System Environment Variables on Windows

2012 Mar 16, 3:13

Is this really the right way to do this? Feels icky:

To programmatically add or modify system environment variables, add them to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment registry key, then broadcast a WM_SETTINGCHANGE message with lParam set to the string “Environment”.

Alternate IPv4 Forms - URI Host Syntax Notes

2012 Mar 14, 4:30

By the URI RFC there is only one way to represent a particular IPv4 address in the host of a URI. This is the standard dotted decimal notation of four bytes in decimal with no leading zeroes delimited by periods. And no leading zeros are allowed which means there's only one textual representation of a particular IPv4 address.

However as discussed in the URI RFC, there are other forms of IPv4 addresses that although not officially allowed are generally accepted. Many implementations used inet_aton to parse the address from the URI which accepts more than just dotted decimal. Instead of dotted decimal, each dot delimited part can be in decimal, octal (if preceded by a '0') or hex (if preceded by '0x' or '0X'). And that's each section individually - they don't have to match. And there need not be 4 parts: there can be between 1 and 4 (inclusive). In case of less than 4, the last part in the string represents all of the left over bytes, not just one.

For example the following are all equivalent:

192.168.1.1
Standard dotted decimal form
0300.0250.01.01
Octal
0xC0.0XA8.0x1.0X1
Hex
192.168.257
Fewer parts
0300.0XA8.257
All of the above

The bread and butter of URI related security issues is when one part of the system disagrees with another about the interpretation of the URI. So this non-standard, non-normal form syntax has been been a great source of security issues in the past. Its mostly well known now (CreateUri normalizes these non-normal forms to dotted decimal), but occasionally a good tool for bypassing naive URI blocking systems.
