Web Monitoring Reliability

clock June 4, 2008 02:32 by author levon
Monitoring Website uptime once every 60-120 minutes is not very reliable method of determining server uptime. Such way of website monitoring gives an opportunity to catch the servers that out for long periods of time, but it is impossible to catch Web servers that intermittently have downtime for shorter periods of time. If tests are frequent the monitoring is much more exact, but the price is significantly higher. The more accurate method is to check every minute or so - for most individuals and organizations it is the only way to be sure that their web sever work without any faluress. Some companies even like to use server 'uptime' as a marketing gimmick - 'Hey, look everyone, 99,99% uptime' - which of course is not accurate - even load-balanced servers can experience a little downtime.

Future of Google AdSense.

clock April 18, 2008 05:02 by author levon
Peter Forret tried to forecast evolution of Google AdSense.

Google AdSense in newspapers: Google reserves advertising space in every circulation. This space is used depending on context.

Google AdSense and Wi-Fi: Google will cover the globe with free POPs. Google will know your exact location and this fact will be very useful for context ads.

Google AdSense and mobile phone: Google redeems cellular communication operator and provides services for free, In return you have to hear short advertising ads before you can speak. These ads are also selected according to context.

Google AdSense on roads: LCD screens are placed on roofs of taxies, on sides of buses and etc. Such screens also have connections with Wi-Fi POPs and ads are different depending on the place, current time and so on.

Such forecast seems to be too much pessimistic and unsophisticated. It is possible that Peter Forret is some kind of paranoiac and is afraid that someday Google will transmit its ads directly to his brains. But who knows!
