ltunify – Failed to send pair request

If you get the error message “Failed to send pair request” when using “ltunify pair” it may be due to that the number of devices you have paired has reached the maximum number.
Check this by typing
ltunify list
If you have 6 paired devices (at least on my computer running Arch) you will get the error message.… Continue reading »


How to split a string using Awk

Using Awk a string may be split at least using two different methods.
Let’s split the strings given in file foo. The file consists of 5 columns separated by a comma (,) so we will split the lines at “,”.
awk ‘{split($0,array,”,”)}{print array[1],array[2],array[3],array[4],array[5]} foo
awk -F “,” ‘{print $1,$2,$3,$4,$5}’ foo
Where foo is a file such as this e.g:
1005.709115,-3.974680,0.081765,3.265020,Wed… Continue reading »


Superconduting gravimeter at Svalbard observes M9.0 earthquake

Friday 11 March 2011 at 0546UT a big M9.0 earthquake happened approximately 200 km outside Sendai, Japan.
The earthquake was observed with a Superconducting gravimeter located in Ny-Ålesund, Svalbard approximately 10 minutes later.
This figure shows what the superconducting gravimeter observed.

Soldiagram benyttes for å visualisere hvordan skyggene kastes fra feks bygninger. Dette er aktuelt ved nybygg og påbygning.
Jeg kan beregne soldiagram og hvordan Solen beveger seg over himmelen sett fra et gitt ståsted feks Oslo.

Visiting Reykjavik

Geodesy at work in Reykjavik, Iceland

My visit to Reykjavik, this time – mid September 2010, was work related.
My original working plan was to make a gravity tie and then demobilize a sea gravimeter.
Prior to my arrival, my contact person at Iceland had informed me that there would possible be a strike by the ship engineers… Continue reading »


Find minimum and maximum using AWK

Let’s assume you want to find the minimum and/or maximum of a column of numbers in a given file using AWK.
Assume we have an input file foo with f.ex. line number in first column and in the second ($2) and third column ($3 in awk) we have the values of interest.

File: foo
1 2 40
2 3… Continue reading »

Harstad og sommersolverv

Jeg fikk et lite oppdrag her om dagen.
Rundt sommersolverv skal noen gjøre filmopptak i Harstad.
I den forbindelse var det ønsket å finne når Solen står i nord og sør for 21. og 22. juni 2010. Altså for dagene rundt sommersolverv.

Harstad kirke Nord Sør
