I have just deployed some changes to the price search which should speed up the search process a bit. You will also notice that the average prices are significantly more accurate because I have increased the sample size to include the entire faceted result (what is used on the graph), rather than a sampling of the graph data.

Just finished deploying the Price Search feature. Right now the search feeds off of the Overall-sale item database. In the future I will also roll it out for the Autos database and probably add some more functionality to specify location, etc…

As of the writing of this post, only ~9% of my entire database is being used, but the sample and results still tend to be accurate (although not all long-tail searches deliver a ton of results). I will keep building the index - shoot me an email with any thoughts.

Just a little FYI — I am hard at work rebuilding the backend of the site to allow for some exciting features. Once deployed, we should see a major jump in usefulness of this site… Stay posted

CLI is old enough to start showing monthly data!

I read a CNN story on tumbling housing prices, so I whipped together a little report over breakfast to reality check. I still need some better data to normalize for seasonality, but hopefully I can get something together soon.

You might notice that the homepage changed to the ‘graybook’ home (Gray Book being a play on Kelley Blue Book). I personally find that data more interesting and useful than the daily price tracker, so I made the swap.

There are a number of enhancements in the queue for the Gray book, so definetely check back later.

It has definitely been a while since the last update. I have been working on a lot lately — primarily figuring out how to scrub the data from invalid/repeat postings (as well as a bit more on the DBA front). Either way, I have reached a point where I think we are relatively close to publishing some usable data. Either tomorrow or the next day, I will be ready to deploy the “Graybook”!

hopefully you find it useful

Also, I havent forgotten about updating some of those overall item prices — I have a bunch of college related stuff in the pipeline. It’s hard to figure out what types of items will have price fluctuations

Last night there were a few changes made

• Many new products added. You can expect another 15 tomorrow
• Consumer Item Pages has been updated to allow for 3 products to be compared against each other. There is a funny scaling issue (zeroes out when there is no data on a particular day) — this will be addressed soon
• Top 5, Bottom 5 car markets are now clickable after not working properly due to a Craigslist update

In the near future, I would look for a big enhancement that should allow for some very useful insight when assessing the value of your goods…

We have just deployed the initial iteration of the Item-level price visualizations. As it stands now, we only have the Xbox 360 prices (generating this data takes time [please keep in mind that we are analyzing over 17 million postings here...]).

There are some interesting other price curves in the queue, so you should be sure to come back to see the data. Please drop me a line if there are any specific requests for items to add to the UI.

The data rendering problem has also been fixed — you can now compare ALL states against each other!!

You might notice a few changes today.

• Google decided to update the visualization API, so the legend is now in a readable position
• I have updated the ticker to have more rows and be more interactive. To keep the data fresh, it now only updates for each trailing 2 days.
• The locale and state averages tables have been fixed, and data should be displaying properly.
• Weekly average graphs are in the queue, and should be up soon
• I have removed some of those hideous JpGraphs
• Built a lot of the backend for better/more interesting data to come out of the personals sections (this should be interesting…)
• Some light framework is being built for low-ticket item info.
