What has Michael Arrington (TechCrunch) been smoking?

By Marcelo Calbucci

 

    Here I'm on my happy afternoon, almost code complete in a super cool feature when I take a break to read some blogs (200+ of them every day).

 

    The big news is MySpace blocking PhotoBucket. This is super interesting for the business that I'm in, so I go ahead and read a few posts.

 

     Michael Arrington on TechCrunch write a post called "Can PhotoBucket Survive Without MySpace?Open in a new window" (Shouldn't "without" be in lower case?). Bla, bla, bla, quote someOpen in a new window otherOpen in a new window bloggersOpen in a new window, argues that PhotoBucket is a destination on itself, can survive on site ads, yada yada yada, then...

 

"...And many MySpace/Photobucket users will simply leave MySpace and go to one of its many competitors rather than lose the ability to embed their Photobucket media ..."

 

    <johnstewartish>Wwwwhat??????</johnstewartish>

 

    Are you kidding me Michael? (I'm sorry, Mr. Arrington -- we are not that close).

 

    He continues...

 

"... Re-creating a profile at another social network takes a lot less time than re-uploading hours of video..."

 

    I'm not sure where to start. Humm... Let's start by the obvious stuff.

 

    Uploading a video takes longer than creating a profile on a Social Network. You win that. I say that buying bananas at the supermarket is faster than ordering a new Dell Server. Ha!

 

    MySpace is not about pictures, videos or podcasting (anyone doing podcasting still?). MySpace is about people. Unless you get a good chunk of your friends to move with you to a new social network you are not leaving.

 

    Contrary to normal people, like 99.9% of the population, Michael Arrington probably buys a new house and move across the city when his favorite organic market moves to another neighborhood, after all, it takes longer to get groceries every year than it takes to find and buy a new house, right?

 

    Will MySpace users move to another social network? Maybe a tiny percentage that won't be enough to be a blip on MySpace management dashboard. More likely, users will start uploading videos to a new service or just add plain old links to their PhotoBucket stuff (I don't think MySpace will block links).

 

    Can Photobucket survive without MySpace? Yes, but it got bruised really bad. They probably get a lot of their traffic from embedded widgets on MySpace and they are going to lose that, thus dramatically decreasing their revenue from ads.

400% perf improvement on deployment

By Marcelo Calbucci

 

    Our binaries and all the necessary files to run Sampa keep growing. Right now, Sampa is a 20MB deployment. To transfer this data from our 768Kbps-uplink to the datacenter can take anywhere from 5 to 20 minutes.

 

    Our deployment script would copy the content and deploy it as it was being copied. The problem with that strategy is that IIS doesn't have all the files ready to switch-over to the new version, so, between the first and last file notification it would take 2-3 minutes, thus, upgrading the Sampa site service would take the system "offline" for about 2-3 minutes. Well, the queue will not stay with a request for more than 90 seconds or so, so a lot of page requests were being dropped.

 

    By doing a tiny change to the deployment script, we went from 2-3 minutes of downtime to 40 seconds!

 

    All that we had to do was to copy the files to a temporary folder and from the temporary folder copy to the target folder. Works like a charm

 

    I always wondered was most applications, during setup, don't copy the content from the CD to the disk and then install if from the disk. That would be so much faster instead of doing disk-seeks on a slow CD-ROM.
