This is a collection of tools and utilities which I have found indispensable as an engineer. Each has a distinct purpose, and I probably touch each at least a few times a week. These tools save me time and I hope that you will find some of them useful as well. Productivity s-tui s-tui is a terminal UI for monitoring your computer. s-tui allows to monitor CPU temperature, frequency, power and utilization in a graphical way from the terminal.

Introduction Isochrones are curves of equal travel time from a certain point of origin, another way of saying this would be that an Isochrone is an isoline for travel time, if the weighting factor is changed form time to distance, then the resulting curve us called an Isodistance. In this post I will present a rough way to create an Isochrone and an Isodistance using google’s directions API. Algorithm The actual algorithm to calculate Isocrone or Isodistance is perhpas a bit complicated than the simplistic approach being described here, if you are intrested in having a deeper look then I would recommend visiting this link by OpenStreetMap folks.

Introduction In this post I will demonstrate how to add custom TileStache map tiles on google maps, using google maps JavaScript API V3. TileStache has emerged as one of the easiest way to render your own map .There are many examples out there on creating basic tiles and then adding them on top of Leaftlet or Openlayers. In this post I will add them as an overlay on Google Maps.
