5×5 for September 19

19 September 2007

I’m getting my rear-end kicked at work right now, otherwise I’d have real posts going up. For now, sit back and enjoy this week’s 5×5. (I debuted this feature last week and explained what a 5×5 is here.)

Five Interesting Prime Numbers (courtesy of the Prime Curios website)

1. 2 (the only even prime)
2. 11777 (It’s an emirp because its reverse, 77711, is also prime.)
3. 8675309 (For 80’s music fans)
4. 103993 (Because 103993/33102 equals ∏ out to the 1/100000ths place!)
5. 555555555551

Five Irritating Web 2.0 App Naming Conventions

1. Having a name that should end in -er but has the “e” left out, such as Flickr, Retrievr, etc.
2. Calling anything and everything “beta”
3. Gratuitous and illogical use of periods to make the name look like a website, such as del.icio.us and bubbl.us
4. Names that do not describe the app, such as Meebo (which is an instant messaging app)
5. Anything that involves the term “mashup”

Five Things I Will Never Do for this Blog

1. Insert text ads
2. Spend more than $50 per year on this blog for any purpose
3. Send around emails to high-traffic blogs asking them to link to me (a.k.a. “link-whoring”)
4. Spend more than 30 minutes a week contemplating my traffic patterns (or lack thereof)
5. Force myself to write when I have nothing to say

Five Bands/Musicians I Wish I had Seen in Concert While They Were Still Around

1. Led Zeppelin
2. Stevie Ray Vaughan
3. Cream
4. The Beatles
5. The 80’s incarnation of King Crimson

Five Halloween Costume Ideas for Me

1. Academician (i.e. just wearing my Ph.D. hood, gown, and tam)
2. Martin Luther (i.e. just wearing my hood, gown, and tam)
3. Henry VIII (i.e. just wearing my hood, gown, and tam)
4. 19th century Protestant minister (i.e. just wearing my hood and gown, minus the tam)
5. Supreme Court justice (i.e. just wearing my gown, minus the hood and tam)
