Sweden's organised crime makes more money from running private health clinics than from selling drugs, warns the agency for fighting economic crime.
So will the right-wing government now send in the military to stop privatisation?

@chu It might or might not be an applicable example depending on the exact context, but what happens in the USSR after it collapse makes blanket statements such as "we won't have electricity after social collapse" kind of problematic.
"I had to then explain that infrastructure needs people to maintain and if things fall apart, nobody will keep the generators going"
To put it bluntly, are you *sure* that operating a power plant, managing a local grid, sourcing fuel and collecting payments from customers is beyond the capabilities of most currently operating criminal organization? I, certainly, am not.
That said, I totally agree on your statement regarding the average person having not idea how much frequent disruptions of the grid, in countries where quasi-permanent availability of electricity is considered a given, will lead to a large number of death and suffering. Disruptions in potable water management, sewage management, and refrigeration can have devastating consequences.

Supporting Ukraine is a once-in-a-generation chance to make the world safer. Ending that support is recklessness for which we will suffer in all the conflicts that the Ukrainians are preventing or making less likely. Let us help those who help us.
I have also added a WN30 remote temperature sensor to the system to monitor the temperature inside the fridge and it made me realize quickly that our fridge is dying and can't maintain a temperature below 10°C which is not at all acceptable for food safety.
I plan to add a second one to monitor the freezer separately.
Overall, I'm quite pleased by the Ecowitt system so far. It's basic, mostly unencrypted, open-ish, low-cost and low-friction.
New weather station installed at the family home. Hardware is by Ecowitt, it's quite low-cost, I'm curious to see how robust it is.
For Europe they recommend to order the 868 MHz version but because it's low-power and each sensor sends only a few bytes every minute, I've chosen to order the 433MHz version. I have thick walls and metal shutters to go though, so I thought it would help to use a lower license-free frequency. So far, it's working great.
The GW2000 base station (connected to the internet router) gives temperature, humidity inside the house and atmospheric pressure. I have chose the GW2000 because it has an Ethernet port and can be plugged into my router instead of the cheaper GW1100 that can only work through wifi.
The sensor on the left of the picture is a WH32 outdoor sensor giving temperature and humidity, it's under a radiation shield. The one on the right is a WH40 rain gauge with additional protection against birds. In the future I plan to install a wind speed and direction sensor (WS68 most probably) but they will be separated from the rain sensor and mounted on the roof, a must to get accurate wind measurement as the garden is full of trees and big shrubs.
Ecowitt has several "all in one sensors" but they won't work for me: if I put them on the roof, it becomes hard to clean the rain gauge regularly (and this is more or less mandatory), if I put them in the garden the wind measurement will be garbage.
All data is pushed to https://www.ecowitt.net/ in my private account and I can decide to share some of the channels on the public map.

#Google is trying again to convince you, YES YOU, to contribute for free to Google Maps.
Please don't.
It is 100% #proprietary, Google has full control over the data you added and people can only access Google Maps over proprietary channels where Google dictates the rules. This gives them too much power.
Contribute to #OpenStreetMap instead, it's a project by the community, for the community.

After basically the whole #Microsoft #Azure cloud was hacked (see list of related sources on https://karl-voit.at/cloud/ ), the first follow-up incidents went public caused by missing containment actions:
60,000 emails were stolen from 10 #USA #StateDepartment accounts
https://www.reuters.com/world/us/chinese-hackers-stole-60000-emails-us-state-department-microsoft-hack-senate-2023-09-27/
If you didn't understand until now: basically EVERYTHING at Microsoft got hacked and Microsoft can't (or won't) get rid of the intruders. Everything authenticated by Microsoft is tainted. Even #Windows auth.

Science is not democratic, but it can be democratized. Scientific findings won't be decided by a majority of votes, but public participation could help political decision makers and the scientific community to choose the right direction for scientific endeavor. The suggested #scicomm reading on this topic is "Democratizing Science", an open-content book by Paola Mattei.

For me, right to to repair isn't just about ewaste, and preventing corporate gouging.
It's about mental health. Being able to fix your gadgets is therapeutic. Empowering. Good for the soul.
In a world full of complex technology it's easy to feel small and helpless. And maybe I'm too much of an idealist, but I think that if everyone could experience the joy of fixing or modifying a gadget now and then we'd all be a little more open minded, a little more daring. A little harder to push around.

My latest hack ‘CyberDeckChair’ is a solar-powered contraption with two modes - cyberdeck and deckchair 😉
In cyberdeck mode, use it as a Pomodoro timer to aid your work productivity. When you’ve exhausted yourself, activate the deckchair mode and recharge in the sun.
Let the CyberDeckChair be a practical reminder to take regular breaks. If devices can lay back to recharge, so can you!!! ✨✨✨
Originally conceived to be fully 3d printed, but why 3d print when you can crochet in 3D 🧶

Is there a scientific illustrator on here who could do a reasonably easy piece of work quite quickly (within the next 2 weeks or so say) for an article I'm writing?
Or can anyone recommend somebody? Ideally Denmark based (for financial simplicity), but elsewhere not impossible...

"Actually, we will read your thesis" by Neel Krishnaswami https://semantic-domain.blogspot.com/2023/09/actually-we-will-read-your-thesis.html
"whenever I find a paper I don't understand, I start looking for the PhD thesis based on it. Nine times out of ten, the thesis is vastly more understandable: "obvious" lemmas will have explicit proofs, algorithms will have detailed pseudocode, and the right intuitions and perspectives to take about the topic will be spelled out."
Can relate. A colleague of mine, Stefan Pulver, once mentioned to me the "strategic reserve of Michael Bate's lab PhD student theses" as something of wonder – he was a postdoc in that lab. Huge amounts of data not deemed splashy enough for publication but full of details and caveats and protocols for studies of #Drosophila larvae #neuroscience.

#SciArtSeptember Day 22: Nocturnal
Owls have large, oddly shaped eyes in order to see in low light. (Ok, this is based off a crepuscular owl, not a nocturnal one, but close enough.)
This is the first 3d printed #SciComm model I made! Available in my Etsy store: https://blueappaloosastudio.etsy.com

#China's space station achieves 100% regeneration of oxygen resources
> "At present, the six systems are in stable operation, with 100 percent of the oxygen resources regenerated and 95 percent of the water resources recycled. This reduces the amount of supplies from the ground by six tonnes every year," said Bian, addressing the third national manned spaceflight environmental control and life-support technology conference on Thursday. https://www.chinadaily.com.cn/a/202304/14/WS6438b2e2a31057c47ebba160.html #China #space
@foone Does that mean terraformation would be a form of piracy? #dontCopyThatFloppy
