Devices and techniques are generally described for anomalous computer activity detection. In various examples, first computer activity data associated with a first account may be determined. A first linear detection event that corresponds to the first computer activity data may be determined. In some examples, a set of gradient-based data associated with the first linear detection event may be determined. The set of gradient-based data may represent comparative analysis of the first computer activity data with computer activity data of other accounts. In some examples, first data representing the first linear detection event and the set of gradient-based data may be generated. In various cases, network access for the first account may be disabled based on the first data.

Anomalous computer activity detection and prevention

A flue gas heat recovery apparatus for reconstituting thermal energy normally lost through the venting of flue gases from a heat liberating plant is disclosed. The apparatus can be employed with forced air or hydronic systems and includes a compressor which draws hot gases from the exhaust flue through a first heat exchanger located in a cold fluid return to the plant, thereby transferring thermal energy from the gases to fluid (typically air or water) flowing in the return duct. The compressor operates to substantially elevate the pressure and temperature of the flue gases passing therethrough and discharges them through a second heat exchanger located in the return duct upstream of the first heat exchanger to further transfer thermal energy from the gases to the fluid flowing therein. Gases exiting the second heat exchanger are directly vented to the atmosphere or, alternatively, are first filtered to remove particulate matter. Additionally, the compressor can be disposed within the return duct to provide still more transfer of thermal energy to the return duct fluid.
