Believe it or not, tens millions of people are still reading Teletext. The biggest provider of on-screen news, the BBC, has shut down its CeeFax in 2012, but many stations all over Europe still broadcast a teletext signal1. There even is a (semi-) regular Art Festival about teletext!
For those not in the know: Teletext, invented by the BBC in 1972/1974, is a digital signal, that puts a 40×25, 8 color character grid onto your screen. Rudimentary (pseudo-)graphics in the form of a graphical character set are available too. The information is sorted into pages (often called tables), from 100 to 899, and subpages2. Weiterlesen →
Is the widely pushed OGC Geopackage (GPKG)(http://www.geopackage.org/) ready for daily use – also as a replacement for the good old Shapefile as an exchange-format ? While QGIS already supports Geopackage (including direct editing) quite well for some time, the format starts to grow up in the ESRI environment. Some good news with ArcGIS Pro 1.4 …
Sport watches like the Garmin Swim or Forerunner-series are widely used. As a Linux-User, I was facing the „problem“ how to get the data on the PC from my Garmin swim (and to GarminConnect) … there are a lot of solutions around on the internet (some very old ones) – the following workflow works fine for me to get the data on the PC and upload it to GarminConnect.
Fooling around with QGIS (v 2.18) global program-settings, I found some interesting setting. It allows the user to copy geo-features directly from the table to the clipboard as GeoJSON (geom + attributes). So, no „export to…“ etc. is needed.
Back to the Future: Using a DEC VT220 from 1983
I bought an actual serial terminal. It is many years older than I am, and can display 24 lines by 80 (or 132) colums of text.
My workflow is quite terminal centric: Work for Uni is done with vim over ssh, emails are read with mutt, and ncmpcpp provides the front end to my music. If it weren’t for the Internet, I’d ditch the display server without batting an eye. Weiterlesen →
Nachdem ArcGIS Pro von ESRI erwachsen wird und sukzessive vermehrt im GIS-Alltag zum Einsatz kommt, anbei ergänzend zur Serie zur Anwendung bestmöglicher Transformationsparameter zwischen dem österreichischen Bundesmeldenetz und WGS84/ETRS89 die Implementierung dieser in ArcGIS Pro (Stand Version 1.3.1).
Have you ever played or streamed sound controlled in a command line? I myself play & stream every sound controlled through command line interface. To achieve that I use an odroid c2 connected to my av-receiver.
Ever wanted to combine two WAN connections for faster* internet? I do, for torrenting. And I scripted it.
On the Web, you’ll easily find „tutorials“ that just give you some bash script you have to painstakingly modify for it to run. This is as simple as it gets! But see for yourself! (code at the end of this post)
The last days media was crowded by the WHO air pollution map. As someone a little bit map-addicted I had a quick deeper look at it and was surprised: It looks like air-(pollution) in some cases stops exactly at political borders…
