American companies will never be able to resist the demands of American intelligence services. It doesn't matter if their servers are located in Virginia or Paris or on the damn moon.
Although the author does not mention alternatives, I think he makes a a strong case for self-hosted services (such as Nextcloud).

Solen är en i det närmaste outtömlig källa av energi och kommer så fortsätta vara under mer än överskådlig framtid. På vilka sätt kan vi utnyttja detta för att lösa energifrågan på jorden? I denna veckas UppTalk Weekly möter vi Tomas Edvinsson som kommer ge oss några av svaren.
UppTalk Weekly den 28 oktober 2022, 31 min 28 s.
Gäst: Tomas Edvinsson, professor vid institutionen för materialvetenskap, Uppsala universitet.
Moderator: Fredrik Engelmark, samverksansledare UU samverkan.

Under the title Data in Motion this track focuses on the deployment of data in research and the versatility of the domain that concentrates on this way of doing science. A panel, presentations and small pitches, illustrated by video or demo's, will sketch the fruits of escience and data science, and thus demonstrate the need for an RDA in support of research. Also the formation of a European Platform for e-science and data research centers will be highlighted during this session.
Video 1h 20 min. Presented by Patrick Aerts and Paul Groth.
Fun little map-based game.
How well do you know your area? Test your knowledge by locating streets on a map.
This looks quite exciting. I hope to get the time to test it.
There's of course Hypothes.is, which is an open standard, but this being built on Matrix makes it all new and shiny :-)

EU:s medlemsländer producerade 13.5 miljoner cyklar (med eller utan elassistans) under 2021, en ökning med 11% jämfört med 2020.
De största EU-producenterna var Portugal (2.9m), Rumänien (2.5m) och Italien (1.9m).
Sverige, Danmark och Finland producerade jämförelsevis få cyklar (ca hundra tusen sammantaget, varav majoriteten i Sverige).
Under 2021 exporterade EU:s medlemsländer 1.5 miljoner icke-elektriska cyklar (en ökning med 16% jämfört med 2020) plus drygt 300 tusen elektriska cyklar (ökning med 15%).
Importen uppgick till drygt 5.7 miljoner cyklar plus ca 1.1 miljoner elektriska cyklar (ökning med 17% och 37%, respektive).
De största importländerna utanför EU för icke-elektriska cyklar var Kambodja (27%), Taiwan (26%), Kina (10%), Bangladesh (8%) och Turkiet (5%).
De största importländerna för elektriska cyklar var Taiwan (57%), Schweiz (13%), Vietnam (11%), Kina (7%) och Turkiet (6%).
During the last two decades, China has made two-thirds of the world’s bicycles (60-70 million of 110 million annually). Most of the rest come from other Asian countries. Europe is back to producing ten million bikes annually, but the US only manufactures 60,000 bicycles per year.

Konkurrensverket har godkänt Synoptiks köp av Smarteyes.
Förvärvet genomförs via moderbolaget Synoptik A/S, i sin tur ägda av Synoptikfonden och GrandVision. Smarteyes blir därmed också indirekt en del av EssilorLuxottica, en världsledande aktör inom optik med över 18 000 butiker globalt.
Synoptiks största ägare är bolaget Grand Vision som ägs och styrs av EssilorLuxottica som dessutom är näst största ägare i börsnoterade Synsam med 6,6 procent av aktierna.
De finansiella villkoren i detta förvärv är inte offentliga. Säljaren av Smarteyes är Mellby Gård AB.

There's a forest of sites out there with the sole purpose of allowing you to test your microphone.
This is the only decent one, as far as I know.
By that I mean it does what it says, runs no ads, and handles your recording strictly client-side.
Recently installed a new webcam by my office computer. Not long after, a thought materialised: should it not be possible to view the video feed over a remote SSH tunnel?
Indeed, here's one way to do it (I have not bothered connecting to the camera's builtin microphone, but that should be possible):
