By

My wife has been in the same Scottish Country Dancing group for many years, and back in 2005 she began keeping a record of the dances done at each meeting. She lists a fair bit of information in her "dances done" spreadsheet (screenshot below). She recently asked me "Would it be possible to get a…

A script to log what my GPS tells me

By

I carry a Garmin Etrex 10 when I go bug-collecting. It's a handheld GPS receiver without many frills, and I only use it to record the latitude and longitude of each of my collecting sites as a waypoint. At the start of a field trip I delete all previous waypoints. When I do this, the trip's…

Eek! My rounding is biased!

By

I've written several BASH scripts that use GNU AWK's printf function to round off decimal numbers. Now I've learned that the rounding is biased, and I need to re-do the scripts. For me the desirable way to round off a decimal is to round up if the bit to be discarded is greater than one half, and…

By

When cleaning UTF-8 text files I sometimes come across invisible characters that I call 'gremlins'.

Gremlins are weird things…

The joys of ISOdates

By

It took me a fair while to get comfortable with the ISO 8601 date format. After so many years of using DD MMM YYYY, my old eyes and brain had some trouble understanding YYYY-MM-DD. Finally something clicked, and I now read 'ISOdates' easily and I really appreciate their advantages. The biggest…

DMS to DD to KML with AWK and sed

By

In a 2014 Linux Rain article I describe a fast 'points plotter' for Google Earth. First I copy a list of latitude/longitudes (lat/lons) from a spreadsheet to the clipboard, then I launch a shell script with a keyboard shortcut. The script builds a KML file from the copied list and opens the KML for…

Grouping things with AWK

By

In this article I explain one way to group data items with AWK arrays. The code is a little mysterious but the results are impressive, especially in my second example! Case 1: Cricket stats The table 'runs' is tab-separated and lists the 86 national team cricket players who scored (or have so far…
