Exceed the speed limit

Image
Last week I worked successfully on tuning and improving the performance of the reverse geocoding engine. We have used a tool, named K6 , to do some load tests. The test consists of doing massive requests to the service using a customized script to generate random geocoding queries all around the world. The first results showed a speed of about 200 queries/second as about 800K in an Hour. Working on tuning SQLite compile and configuration parameters we are able to surpass 1 Million queries in an Hour , about 300 geocoding queries/seconds. The decision to use SQLite than other DBs, like PostgreSQL, was deliberately done by design. There is a small presentation that explain this decision. We have also fixed a problem of instability of the service (crash), that emerged during the tests. We apologize to our users or customers (apparently no one 😇) for the abrupt interruption of the service caused by our stress tests. As I'm writing this text, a big load test of 24 hr is undergone...  ...

New Feroeg Logo taken from Stargate

Two of three people I showed the Feroeg website told me that the logo was missing. The truth is that the logo was so ugly they haven't the courage to say that. So I have started to think for a 'new' logo for the Feroeg reverse geocoding service. The inspiration comes from an old sci-fi movie that was out in the 1994: Stargate. the story is based on the finding of an ancient, big ring: the stargate. This artifact was used by our ancestors for traveling to the stars, transporting people from earth to another world in a few seconds.   The image on the left as you see is the movie poster. The logo is based on a hieroglyphic present in the stargate. The logo is representing the 'Point of Origin': the earth. Where is the logo, then? Visit our site to see it! In the meanwhile, we have integrated the OpenAddress data set into the service. It is a big improvement in accuracy because it contains millions of street address numbers, but I have noticed a slow down in the servi...

FEROEG a free service of Reverse geocoding

Image
Good morning. In this first post, I want to introduce Feroeg, a free service of reverse geocoding. Reverse geocoding is the process of converting a location as described by  geographic coordinates  (latitude, longitude) to a human-readable address or place name. So, if you think that your company, or yourself, can benefit from this kind of service, please give it a try visiting my web site, www.feroeg.com . The data are taken from  OpenStreetMap . At the moment the service is at the starting phase. Other features and improvements will be added, as the posts in the blog.
