I have added a short review of the M=2.4 earthquake last week recorded with the MSS network. The earthquake was most likely not felt within the region of the MSS network. The epicenter was slightly outside of the MSS network region. In the video on the review post you can see the seismic waves passing the network.
@jayrope Reliable sources for near-realtime data from global seismic networks are https://ds.iris.edu/ds/nodes/dmc/services/seedlink/ and https://geofon.gfz-potsdam.de/. The data is served using the seedlink protocol. A python seedlink client is available in the obspy package ( https://docs.obspy.org/packages/autogen/obspy.clients.seedlink.easyseedlink.EasySeedLinkClient.html#obspy.clients.seedlink.easyseedlink.EasySeedLinkClient). Let me know if you need more info or support.
I'm currently switching from GNUcash to a plaintext accounting software. I'm using beancount, beancount-mode for emacs and the fava frontend. Right now I'm experimenting and learning how to use the beancount features using my last years data. It's looking promising and I can't wait to use the python API of beancount to create custom reports.
Starting the year making up a workflow for self-printed photo zines. Just got the first test run of a set of printed sheets. I'm using FOSS software only for device calibration, layout and impositioning. Only the printer software is proprietary. Unfortunately high quality printing under Linux is not yet possible with free software.
@jayrope No, I'm not using the LOM Geofon for the recording. I use dedicated seismic equipment to record the data. My focus is on the low frequent seismic wavefield which has a lot of content below 20 Hz. Although the LOM Geofon uses a seismic sensor similar to those that I'm using, I don't know how sound recorders treat the low frequencies. I guess they filter them out. From an accoustic point of view, the LOM Geofon is a very sensitive contact microphone. Let me know if you need more info
Emacs org-mode, orgparse, Jinja2 and Latex are my tools of choice to implement an intuitive text-based ERP system for my small company. Feeding data from org files to Latex templates using orgparse and the Jinja template system is working great.
My Jekyll Homepage https://www.mertl-research.at/ is available in two languages. I have written a Jekyll Plugin which allows the handling of multiple languages. I have tried the jekyll-multiple-languages-plugin first, but it contained too many monkey patches and changes of core classes. So I have written a custom plugin that uses Jekyll Hooks only.
There is no documentation yet, but you can take a look at the code on Github.
The Grove DIY – An overgrown pub carpark transformed during lockdown
@jayrope I'm using geophones. LOM uses a similar type of sensor in their "Geofon" contact microphone. Acutally I have supported LOM selecting a suitable geophone sensor for their application.
The Viennese high fog has settled, so uniform light is guaranteed. I took this opportunity to take photos from St.Marx DIY, which has grown quite a lot this year. Just started the structure from motion workflow. Let's see if I have captured all important details, or if I have to revisit the site to fill in some gaps.
