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

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 :(

yes, happy #IPv6 day to all - though here at #ITUniversity it is not being celebrated ;)
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? "Average salary" 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:

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's owner.
not sure it makes sense to send complaints to them ...
"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...
