Additional Factorial Set

There is only one Additional Factorial Set, which is 6.

The factors of 6 are 1, 2, 3, and 6.

If you add all factors except the last (which is the same as the resulting factored answer), you receive the same answer (6).

1+2+3 = 6;
2 + 3 = 5; 5 + 1 = 6;

So far, 6 is the only number that is able to do this.

Pretty cool if you ask me.

DLO - Jam Jacket for the 30GB iPod with Video

I recently purchased the new Jam Jacket by DLO and it's easily the best silicone case for the iPod. This case allows you to lightly drop it onto any surface and not worry about a hard exterior case crack itself or scratch the iPod itself. The only thing missing is a screen protector, in which I'll probably make one from an unused transparency sheet (cut to size, of course).

A Suggestion for RSS Feeds

I've been looking into more and more RSS feeds and have noticed a few flaws in the way rss feeds operate. I would like to recommend future formatting of feeds to include these features to help feed parsers more effeciently.

1. Unique post identifiers
   
   
   
   • This will aid in providing the feed parser to know whether a previously updated entry is a new post or merely an updated post. Instead of relying on titles, descriptions and links, the only thing a parser would need to do is provide the Unique post identifier. This is for recurring rss parser engines and not single-run parsers such as Google's 'IG' homepage.
   
   
   • This will prevent duplicate/errornous feed entries while archiving xml feed
   
   
   • [A-Za-z0-9] string, length: 6~32 characters
   
   
   
   


2. Always define the TTL value
   
   
   
   • This will prevent feed parsers from downloading the RSS feed more than once in a given time. Most default values for smarter feed parsers is somewhere between 30-60min, but most manual feed parsers are able to download the feed whenever the user opens up the application.
   
   
   • This will prevent bandwidth usage when it isn't required.
   
   
   • [0-9] integer
   
   
   • citation: RSS 2.0 Specification
   
   
   
   


3. Create mini-rss feed
   
   
   
   • A 'mini' rss feed can be used by feed parsers to conserve on bandwidth usage. A small file will be downloaded by the feed parser that will have a small numerical value such as a UNIX-based date of the last updated (note: not date of current reading) entry. This small feed url should be included in the master XML file.
   
   
   • (code) Inclusion code inside master xml
     <channel> ... <update>http://.../mini.rss</update> ... </channel>
     
   
   
   • (code) Actual mini xml
     <update>200601160026</update>
     
   
   
   • [0-9] integer
