With the amazing images coming back from Juno's flyby of Io, I finally took a stab at processing some JunoCam images. This image shows Io's north polar region from 2839km distance.
JNCE_2023364_57C00022_V01 Capture time: 2023-12-30 08:37 UT Height above surface: 2839.6 km Jupiter's innermost moon Io as captured by the JunoCam instrument during Perijove 57.
I processed this image from the individual framelets, which I preprocessed with a python script and then assembled in PTGui. This allowed me to retain the complete horizon which is often lost with JunoCam images.
I also developed a color calibration for the JunoCam filters based on the CIE1931 color system. This allowed me to process the image in approximate true colors as the human eye would see them.
However, this wasn't an easy task because the JunoCam RGB filters don't match the spectral response of the human eye very well. Particularly the red filter is way too sensitive in the near infrared and Io's surface is especially reflective there.
In addition to the common ColorChecker 24 spectral target I used an Io reflectance spectrum (Spencer et. al. 1995), so I could better fit my calibration matrix to the spectral characteristics of Io.
Even with weighting the Io spectrum, my calibration only managed a dE of the Io reference target of 8.3 which really isn't great. That's why I'm only calling it an "approximate" true color image for now. There is probably room for improvement by using more representative spectra.
Even with those compromises my image still looks rather similar to @volcanopele's Galileo true color processing of Io. I might try to process/calibrate some Galileo and Voyager images in the future. planetary.org/articles/2629
Thanks to its active volcanic activity and sulfur-rich surface, Io is one of the most colorful worlds yet seen in the Solar System, save the Earth of course
what are the red in the upper right part of the image? Looks like wind spread it in lines? Oh oh and what is the orange/yellow ring in the lower right part?
We’ve never had a major city completely devastated by a surprise weather event before and people don’t even seem to register it happened for the most part.
It won’t be the last time a city is destroyed for that reason, either.
Thanks for sharing the message and all we can is hope that "WE" do something. I suspect we won't as the economy will take a hit worldwide and conceivably trigger a great, great depression. At least that is the fear. So - lip service and hope for a silver bullet?
So much of the $$$ backing RW candidates is coming from the #FossilFuel & beef industries. When you fight climate change you're also fighting fascism & theocracy.

1000 richest people are approched. "The end of the world is here. Time to go to your doomsday bunker", they are told. The billionaires nodded. They knew this was coming. They were prepared.
So they gathered their loved ones and locked themselves in luxury bunkers. No contact to outside world.
10 years later they emerge. The world has healed. The air is breathable, people are happy. "What was the catastrophy?" they ask the first person they meet.
ok, there are illusions but they are not arbitrary as your discussion implies. I your example, the brightness, not color, illusion is due to the surrounding intensities and how the visual system emphasizes relative ove absolute intensity. Necessary as most objects only reflect light and relative intensity is what is more important than absolute intensity. So this illusion illustrates a visual strength not weakness.
@sintrenton @dlmayhem It seems that Tuta has for unexplained reasons recently dropped support for Javascript, so if you have sensibly disabled WebAssembly for security reasons, Tuta will unhelpfully just tell you to upgrade to a more modern browser, even if your browser is already latest version.
Could this possibly be the reason for Tuta failing in your browser?
@sintrenton @dlmayhem Thanks @Tutanota for the link to the blog post which I did not see before, this explains motivation for using WebAssembly over Javascript and good overview of workarounds, although unfortunately users who are using web clients without WebAssembly only see the error message "Seems like your browser is not supported or outdated" which is not an accurate diagnostic and misses the explanation given by the blog post.
In the blog post it says that compiling the C code to Javascript "would make the app too slow to be practical", I am curious what are the numbers for this? Like how much longer would it take a client to sign in using compiled Javascript instead of WebAssembly? And would it be a matter of seconds, minutes or hours to sign in?
I switched from Internet Explorer 6 to Mozilla Firefox 2.0. After Chrome came out, I tried it a little bit, but every time I went straight back to Firefox. I'm still using Firefox today.
Vivaldi user here. I know, it uses Chromium, but I just love the customization of Vivaldi. The lack of native customization in Firefox and some stability issues with the android app made be go back to Vivaldi after using Firefox for a few months.
I think Google just reached to a point where they are certain that they don't have to please their chrome users anymore. They have plethora of products that have a monopoly or nearby monopoly. And their services are tied up with one another. They know chrome can survive even if they implement all their shitty decisions. There are too many huge forks like Brave and Vivaldi that will die once chrome stops development. Which is why chrome won't die or lose to firefox. We should also take a note that majority of the people who use chrome won't even mind about it. That's why they are so confident.
Won't users of chromium forks to drop the MV2 extension as well? I can't imagine that the Chrome Web Store would continue to support uBlock Origin in the MV2 format.
That Reddit post does not point at anything official from Google supporting that click-bait post. The closest you get is this post: developer.chrome.com/blog/resu…
None of these posts which you highlight in that image confirms that Google will deliberately target uBlock Origin. It is a collateral damage, though, with the MV3 move; yes. But it is not targeting uBlock Origin explicitly - as that headline indicates.
I completely agree that using Google based services and products is highly risky in regards to privacy, including Google Chrome (and most likely Chromium). But at least try to stay true to the real facts and not hype a click-bait.
This kind of posting you do here more makes me sceptical to Tuta. This is poor propaganda. If you want to do this kind of stunts, at least know you provide the real hard facts.
And misleading as hell. Headline talks about uBlock Origin, text then talks solely about MV2 extensions.
No word that MV3 also supports almost all features in a fork called uBlock Origin Lite. They even have a handy list of the supported features.
No word if Firefox pledged to keep access to that one (open to abuse) API forever. So will they remain working or will the same problem show up in a short while again?
Tor Browser isn't very secure though IIRC because it's often late to the patch party. So rather use it for exactly the things where you need TOR.
I wouldn't recommend Brave though, the boss is a prick who financially supports homophobic laws. And it's deep in the crypto bro scene. Also it's based on Blink and if they don't keep manually supporting Manifest v2 they will eventually remove it as well ^^'
I highly recommend just using Firefox and going through the settings to e.g., force-enable DoH and certificate transparency, clear cookies on quit (+allow list), disallow third party cookies, etc.
Been using Firefox for almost as long as I can remember. Sometimes, if need be, Safari. Why would anyone use Chrome? (Yes I know it used to be required by some applications.)
Will they? Or rather they keep using Chrome because they never experienced ad-free web, so they don't miss it, so they have no motivation to fight it. I find people are used to ads, accepting them as part of the life.

Sending #SEO #spam to a @EU_Commission post about climate change won't help your reputation, though. Please stop doing that as it will impoverish the #Fediverse as a whole and only land you on #FediBlock lists.
If there has been deception, was it due to oil majors deliberately misleading the public or merely expressing uncertainty about effects of climate change?
#COP28 ? You mean the meeting in one of the biggest oil exporters in the world, whose President is the head of their national oil company and also a a very vocal climate denier?
It would have been better for the EU to boycott it. To be honest, if I described what a fit punishment would be for Al Jaber deliberately sabotaging our efforts against the climate and helping to doom all our children, I'd be thrown off this site.
- Many "oldies" know thi very well. They just don't care. They'll be dead when all this starts getting legs. Climate policy is decided by a highly conservative geriatric electorate, by and large and these people vote reactionary conservative. As in - they do not accept higher taxes or a diminishment of their freedoms, cars, vacays, consumerist lifestyle, pensions. Or lower investment revenues... Climate change is expensive, so the motto is - postpone, delay, postpone, drag feet.
Can we have an International Climate Court where the fossil fuel cartel gets tried for crimes against humanity?
When you keep drilling while island nations sink, frack while wildfires burn Innocents, and look for more oil while extreme weather events kill people, you are guilty of crimes against humanity.
You make serial killers look like amateurs, and you deserve prison at the very least if your profits come before people and our planet.
I want to say the most important measures lack priority:
car free cities, permaculture, passive heating/cooling building design
car-free itself saves time, lives, money, energy and is economically vibrant. car centric design is financially insolvent. It is climate mitigation and adaptation. It costs far less than renewables and especially EVs. It the pathway for a sustainable future developing nations can embrace.
Might be wise to let the oil lobbyists there know that once sea levels, droughts, and other climate disasters displace a billion people (IIRC), some of them might be really angry. Some of them might even think of oil lobbyists and executives as personally accountable. Some nations might, too. I know that catastrophic sea level rise happening before the decade is out feels like forever from now (a whole six years), but I don't know that I'd want to live like that.
Oh, the same climate conference a huge portion of the attendees took private jets to, to make back room deals with fossil fuel companies? The climate conference hosted by a goddamn Saudi oil baron? THAT conference?
are you able to mention one single (serious) measure you took to fight global warming? Please notice that speaches, declarations, etc are NOT really measures.
I always find it kind of fascinating how big companies can be so useless for so long, and then suddenly so active when things escalate — like, they had all the information, they knew what was going to happen, and still they didn't do anything about it until it became an emergency. Why?
I mean I do that too, but that's just ADHD, I don't think companies can have that.
Glad you managed to get this sorted. Unfortunately it's still affecting us and without such a large platform and audience I don't see any hope of us getting Microsoft to resolve it.
@lisamelton I miss the leverage Twitter gave people with customer support issues. It’s good to see that hasn’t died.
But I feel about this the way I feel about stories of people donating money for someone’s medical issues. It’s great that worked, but the system is still broken.
I have been messaging you on X and on Mastodon in regards to accidentally deleting my entire account one I was suppose to delete one legendary account, could you please reply to my posts on either here on Mastodon or on X please as I want to keep the @tuta.io email but God rid of the @tutanota.com email is this recoverable by any chance please? I messaged you just over 24hrs ago.
The Global Monitoring Laboratory conducts research on greenhouse gas and carbon cycle feedbacks, changes in clouds, aerosols, and surface radiation, and recovery of stratospheric ozone.
I remember when small experiments to test how high CO2 would affect plant growth used 350 ppm for the “high CO2” treatment. The world has blasted past what we viewed back then as a disastrous number.
Microsoft Outlook is blocking all emails from tutanota.com as spam. @Tutanota is understandably not happy at "radio silence" from Microsoft's support team.
