identi.ca and Penalty of Success

July 3rd, 2008 by smp | Comments | Filed in Life

The latest “rage” flooding through the social-media world is identi.ca, a Twitter-like micro-blogging service that is built on open-source servers and code.

As with anything that becomes an overnight sensation, the problems of success tend to follow. Using GrabPERF, I have been monitoring the HTML download time of my personal message stream. The results have been interesting.

identi.ca-Jul02-032008

Much has been made of social-media leaders that says that this is a clone, and that it is slow, etc. But, as has also been noted, it is:

  • A one-person operation
  • open-source code
  • willing to admit that it needs to grow.

So, one-day never makes a performance trend. Over the last week, in my day job, I have watched a large online retailer suffer a similar fate to this newcomer to the social-media arena.

And if everyone who was willing to wait for Twitter to recover waited ten seconds for identi.ca to catch up, then there is a good chance that it may stand a chance of becoming a true competitor, pushing performance improvement.

Plurk was a non-starter for the twitterati. Jaiku has lost momentum, and is failing Google in the same way that Orkut did. And Pownce…what is that?

I hold out high hopes for identi.ca, if only to keep Twitter truly honest.

The Twitter Debate - YATPBP

May 31st, 2008 by smp | Comments | Filed in GrabPERF, RANTING, Web Performance

Yes, it’s YATPBP (Yet Another Twitter Performance Blog Post).

About 10 days ago, I turned GrabPERF loose on Twitter. Now before you accuse this of crippling the service and bringing it to its knees, realize that GrabPERF simply requests a document over HTTP about two times a minute. No additional requests are made for images and the like.

In the ocean of requests coming into the Twitter systems, the GrabPERF requests are like individual water molecules being added to the pool.

Twitter - Public RSS Feed, 1Day

The above graph shows performance for the last 24 hours. The purple dots are errors. Complete details, and a dynamically updating graph, can be found here.

Now that I have had a chance to show off, I will leave the Twitter team in peace. I am not a developer or a systems expert. I, like most people, rely on people with specialized skills to analyze and resolve the problem. There are many people on the Web who have taken on the challenge of reverse-engineering Twitter to try and determine how it does what it does, and how they would build a better mousetrap.

Ok. Go do it. Or shut up and let the Twitter team get down to the hard work of making this service work. Or volunteer to help them fix the problems.

The Twitter team has stated that they know how to resolve the issues that are at the heart of the performance issue. But as I said in a comment to @gapingvoid tonight, knowing what the solution is only makes up 15% of the application development process. Building, testing, deploying and verifying the solution takes 85% of the effort.

The Twitter team has a lot of work ahead of them. Buy them beer and pizza and let them get to it.

The fading of blogging

April 13th, 2008 by smp | Comments | Filed in Life, RANTING

Through 2007, the number of posts I made per day/week/month decreased steadily. I know post new items 2-3 items a month, or less. After 2 years of steady entries, I just didn’t have anything to add to the conversation.

Having been an A-list groupie for this entire period, I lost touch with the self-perpetuating scene. A comment that I saw on Top Gear summed it up: Jeremy Clarkson had another chat show host on, and they both commented on how all British chat show hosts end up appearing on each others shows.

That’s how blogging began to feel to me. I began to step back.

I stepped back from true, active day-to-day management of GrabPERF.

I drifted, intellectually and emotionally.

I found the sharp edge of my humor, which had wandered off and gone hitchhiking through the British Isles disguised as Roger Daltrey for six months.

The last few weeks I have been asking myself if I want to go back to blogging, if I want to continue to produce the random ideas for the world to see.

The death of my grandmother a few weeks ago brought my world back into sharp focus. Who is going to see these stories, these tales? Who will be the keeper of my intellectual flame? What will people know of me when I fade away.

I will be trying to storm back. My brain is here.

I AM THOR, GOD OF THUNDER.

Ok…maybe that was delusional. But hang on for another wild ride.

New GrabPERF Measurement Locations

January 11th, 2008 by smp | Comments | Filed in GrabPERF

I know that I have been bad at blogging news about GrabPERF, but today there is some. In the last two weeks, we have added two measurement locations: Washington DC AOL and Argentina LaNacion.

Thanks to Carson Evans of AOL, and Jose Falvo and Leonardo Lancellotta of LaNacion for helping out with the installation process.

mon.itor.us Outage

November 5th, 2007 by smp | Comments | Filed in GrabPERF, Web Performance

mon.itor.us, a service which also provides free Web performance measurement services, appears to be having a wee problem.

mon.itor.us-nov052007

The most recent GrabPERF data on this site is available here. The issue may be corrected by the time you look at the data.

I don’t wish suffering like this on anyone. GrabPERF had it’s own 3-4 day outage a few months ago. It’s just sad to see when monitoring services go down.

GrabPERF Return to Service

September 20th, 2007 by smp | Comments | Filed in GrabPERF

GrabPERF returned to service at approximately 17:30 GMT (13:30 EDT — 10:30 PDT) September 20 2007. The database server was on all night, but an esoteric choice of primary interfaces (i.e. the least obvious one!) meant that it was taking to empty space.

Have fun and enjoy the data!

GrabPERF Datacenter Move

September 19th, 2007 by smp | Comments | Filed in GrabPERF

GrabPERF has been offline all day, and will likely be offline for the remainder of the day as Technorati relocates the servers to their new datacenter.

Sorry for the inconvenience.
