Swimming Pool

Got laid off from Pronto.com on June 10th. I won't go into the details, but it apparently wasn't due to my job performance and I have a rehire-able status with IAC. It was a bummer, but I'm not letting it get me down.

I spent the day today at the Sunset Pool in Longmont and I really had a great time. It was like reliving my childhood getting sand everywhere and seeing all of the college kids in their bikinis made me want to hit the gym. My kids had a great time and so did I. I really enjoyed reflecting and not having to worry about my ticket queue at work or worrying if the boss was going to chew me out for something. I really got some destressing time in and I loved every minute of it.

Sunburn, chlorine and flopping around in the pool makes me sleepy.

Let me guess. You googled for "squid no Last-Modified header", huh?

Short answer: squid will not cache your object if there is no Last-Modified or Etag headers in the response from the source. Period. You may go about your day. :)

A friend of mine at work today said that he wanted to change his browser's useragent to Mosaic (the first browser, circa 1992-ish). I was thinking that would be awesome! Could you imagine the Facebook people looking at their UserAgent reports and seeing a growing, if not significant number of users using a Mosaic browser (doesn't render javascript, css, no plugins, etc ...) Barely any sites would even render properly much less work in Mosaic. If you're interested, here's a few Mosaic UserAgent strings. I may use it as the default in my crawler. :)

Mosaic/2.1 (Amiga ARexx)
Mozilla/1.0 (compatible; NCSA Mosaic; Atari 800-ST)
NCSA_Mosaic/2.0 (Windows 3.1)

I particularly like the Atari 800 one. :)

Ok, here's my stand on things. The beauty of having a blog and speaking publicly about things is that I can be proven right or wrong - only time will tell.

People have been clammering for 10 years about the end of the IPv4 address space and as of today even CNN has jumped on the bandwagon. My prediction about the IPv4 space is that it will take tens of years before anyone makes any real changes much less adopts IPv6 across the board.

Last week, Comcast has announced that they're going to offer IPv6 routing across their network, but will require tunneling outside of their network still since the rest of the world is still not IPv6-compatible.

Facts:

There are still large organizations who own huge class-A chunks of the IPv4 address space. Some of these are military organizations. You can bet that the majority of these addresses are not in use today. So, there are plenty of IPv4 addresses out there, but nobody wants to let go of them. When IPv4 addresses become scarce, these addresses will be sold to the highest bidder instead of people adopting IPv6.

People are lazy. Not everyone, but the great majority of people are. Lazy people tend to take the easiest way out. The easiest way out is not to create something new, it's to squeeze the last little bit of life out of something.

People will scrape together and consolidate their IPs if they run low.

People can port-forward ports to NAT'ed machines instead of needing a new IP for every new service. Wow! We have 64k ports on each IP address! Who needs more than one now?

VPNs take care of native access from site-to-site from private address to private address. One public IP on a single machine can link together millions of machines in a huge organization and can delay the need for IPv6 for a *LONG* time.

NAT

Large companies can work off a single IP. Just make each service a "directory" off their main domain, so http://google.com/search and http://google.com/docs, etc ...
