When I plan a cycling trip I search for tracks in the target area and try to maximize the “fun factor”. Thus I often end up with a bunch of tracks from which I want to use parts. The difficult task is to cut, sometime reverse and combine the source tracks into a planned track. Most of the times this seems a too much waste of time since it involves a number of operations in qlandkarte (cutting and combining) and gpsbabel (reversing)....
Do you still have your first computer? Your first laptop? As years go by we tend to accumulate a lot of old hardware which, at least in our mind, hold some value, at least a sentimental one. Yes, I still have my first laptop but I also have many generations of hardware of all types in between. How can I throw away that server which I used for 3 years, it must be still usable somehow!...
This weekend was cloudy and it rained so I decided to give some more time to play with my android phone. Even since I got the phone some time ago I tried on several occasions to do some fun development on it but it never seemed quite fun as expected so beside some play with the sensors, gps and camera I did not do much. However this time I was decided to do a different kind of test....
Since I started paying some attention to the photos I make the display calibration issue recurrently came into question. I tinkered as much as I could with xgamma mostly with bad results. This weekend however I could borrow a Spider 3 device and I played with dispcalGUI and argyll. There is not much I could say because the doc on the respective sites is great so after some wait I managed to get and ....
This is a simple script which reverses the direction of a gps track stored in a gpx file: <pre lang="bash">#!/bin/bash gpsbabel -t -i gpx -f $1 -x transform,rte=trk,del -o gpx -F 1.$1 gpsbabel -t -i gpx -f 1.$1 -x reverse -o gpx -F 2.$1 gpsbabel -t -i gpx -f 2.$1 -x transform,trk=rte,del -o gpx -F rev.$1 rm 1.$1 2.$1 will generate a rev.file.gpx from file.gpx Comments: Gon - Apr 5, 2015 However the timestamps will be now in a wrong time order… It would be cool to be able to maintain the time gaps between trackpoints together with the start/end times....
After a few days play with my new Dell Latitude E6410 I was expecting more from the “Ubuntu on the new laptop” combination. Here is a short summary for what to expect if installing Ubuntu 10.10 Maverick Meerkat on a E6410 (check the previous post on the subject). Video card – nVidia Corporation GT218 [NVS 3100M] (rev a2). Works with default version Nvidia driver from Ubuntu but the log is full of errors:...
Did I missed the old times when installing Linux on a laptop was a bit tricky? I seems so since installing the latest Ubuntu (10.10 Maverick Meerkat) on a Dell Latitude E6410 (with Nvidia graphics card) was by no means a breeze. Update 20100115: I summarized/updated all the hardware part in a separate article, check for updates. Installation All started when, full of confidence, I booted the usb stick with the Linux install expecting everything to work as a charm and ended up staring at a black screen....
I order to migrate contacts from a Sony Ericsson C510 to a HTC Desire you first have to export them in an usable format. Wammu recognizes this phone and exports a .vcf file containing all contacts. However there are some major limitations to this process: entries which contains multiple phone numbers are exported separately instead of a single vcf. For an entry named “me” containing a mobile and work phone the exported file contains a: me/M and me/W contact BEGIN:VCARD VERSION:2....
