Science and Insanity
Insanity: Repeating the same process, expecting a different outcome.
Science: Repeating a process in order to verify a previously-observed result.
Conclusion
There is a fine line between science and insanity.
Everyone is familiar with the contributions of technical moguls such as Bill Gates and Steve Jobs. Likewise, computing history remembers people like Charles Babbage and John Von Neumann. There are many lesser-known, but equally-important figures, whose contributions made our current “online” lifestyle possible, and made computing both affordable and physically small enough to be almost ubiquitous.

Security issues and design flaws can be costly to fix, once an application has already been written.
In spite of everyone’s best efforts and intentions, these are some additional, common mistakes that can be made during the application design / development process.
While trying to write an options page and leverage persistent, admin-configurable settings for “JP User Registration Blacklist“, I found a maze of conflicting standards and options.
This is my attempt to provide a simple, straightforward, and comprehensive example, with source code that you can copy and implement with your own plugin.
On the PS4, any online gaming requires a $50/yr membership to Playstation Plus, where the PS3 could do basic online multiplayer gaming for free on PSN (Playstation Network)
WordPress Plugin: JP User Registration Blacklist
Check out my first WordPress plugin, which you can view here:
JP User Registration Blacklist
The main purpose is to prevent spammers from registering as a user of the site.
Features:
- (Version 1.7) E-mail confirmation token
- Asks a simple math problem during registration
- If the user’s e-mail or IP address is listed in the Comments Blacklist (Discussion Settings), it prevents them from registering.
- Lists the user’s IP address in the “website” field, allowing the user to see the IP from which the user registered.

Background: Like the undead, Windows XP’s installed base continues to live, even after the Microsoft-published End-Of-Life (EOL) date of 4/8/2014.
What “End of Life” means, is that Microsoft no longer provides free updates, namely security updates, for the operating system.
Unlike other Microsoft operating systems, and due to many factors, Windows XP has a huge installed base.
This article details the XP EOL event, including the good, the bad, and how Microsoft could have handled this better.

Summary
Drinking COLD beer has an actual health advantage (over drinking warm beer)
You can shave 8 to 10 calories off your beer by drinking it cold!
Water weighs…
8.345 pounds per gallon.
A pound is 16 ounces. If water was 8 pounds per gallon, a gallon of water would weigh 128 ounces.
A cup is 8 fluid ounces. Two cups is a pint, and a quart is two pints. A quart = 8 * 4 = 32 fluid ounces. A gallon is 4 quarts, therefore a gallon = 4 * 32 = 128 fluid ounces.
Therefore, one fluid ounce of water approximately weighs one ounce.
The actual number is 1.04 oz / fl oz, assuming that the discrepancy is due to our accuracy of measurement improving over time.
Likewise, a pint of water (2 cups, or 16 fl oz) weighs about 1 pound.
This is similar to the metric standard, where 1cc of water = 1ml = 1g.

Although details are very limited at this point, the press release states:
…the companies have established a more direct connection between Netflix and Comcast…
There are those who are either concerned that this violates the concept of net-neutrality, or speculate that this is a “game changer” from an internet economics perspective.
In reality, this is an incredibly smart move for Netflix, and a tremendous win for Netflix / Comcast customers.
