Aware that the #ITU #mastodon node is but a little appetizer and demonstrator, with most of us having other primary accounts elsewhere, we happily welcome new users @mogel@social.itu.dk and @ieso - writing an #introduction (with some of your favorite hashtags) is a good way to get in touch when you are new on #mastodon

&quot;The Trump administration is targeting one of the world’s most trusted sources of #climate and oceanic data—the Ocean Observatories Initiative (#OOI). According to the New York Times, ships will be dispatched this month to remove the more than 900 deep-sea instruments that comprise the network, which, for the past decade, has collected crucial data on physical, chemical, geological and biological conditions from all layers of the Atlantic and Pacific #Oceans... &quot; https://www.s...

&quot;This paper analyzes and identifies a space-based Global Navigation #Satellite System (#GNSS) interference source that has caused scores of powerful transient wide-area interference events over continental #Europe, #Greenland, and #Canada since 2019. ... these techniques to confidently identify the GNSS #interference source as a constellation of #Russian early warning #satellites in Molniya (“lightning”) orbits&quot; https://arxiv.org/abs/2606.03673

i m not sure i had seen this before - the links service on #truthSocial https://links.truthsocial.com/ being used for #phishing campaigns, with (rather good) complete copies of danish web/#dns service https://one.com , encouraging me to renew my #domains there. such usage kinda fits the site&#39;s owner. not sure it makes sense to send complaints to them ...

Very happy to be working with my friends and colleagues in #Nepal again. Our oldest memories go back nearly 20 years, when we deployed #wifi in the #himalaya - two old pictures included. #mastodon presence in #Nepal still small (i guess) (pls shout if you are in Nepal!) and anyway this post would be invisible to them, as my university has a #geoblock against all of Nepal ... duh :( #wireless #NepalWireless #NREN #Nepal workshop 2026 #Campus #Network Design and Operations #NSRC #Kathmandu

My university uses #Geoblocking of known evil countries. #Geoblocking is a very sensible and appropriate security measure, as it ensures that only those with evil and hostile intentions get to your sites - because for those, geoblocking is easy to circumvent - while all normal naive believers in global connectivity - such as scientists, academics, students - are left out. I commend the use of #geoblock #science #university #network #nren

Power of #data: I heard today in a talk that the average #salary in #Kenya should be EUR 300 - 500 ... knowing Kenya well, i could not recognize that. The explanation? &quot;Average salary&quot; is measured among those with jobs in the formal sector - which is ... 17% of those in workforce. The reality for the vast majority is way lower. Some data: https://wage.is/kenya/ #low_salary
