Your mind will answer most questions if you learn to relax and wait for the answer.

― William S. Burroughs

I've got a hobby-interest in remote sensing (satellite imagery). Over the past couple of days, I've been playing around with data from the ESA's Sentinel-1 mission. The ESA (being cool and European Union-y) makes most of the data from Sentinel series of satellites freely accessible to the public, and provides some decent software for processing and analysing the data.

Sentinel-1 is a synthetic aperture radar (SAR) satellite. I don't fully understand the physics behind SAR, but it's basically an active radar measurement of the ground track the satellite passes over. Different surfaces give different sorts of radar returns (measured as a change in polarisation), and so SAR can be used to classify different terrains (crops, forests, grasslands, rock, etc), like in the false-colour image of Flevoland I've attached. Resolution is moderate: for Sentinel-1, each pixel ends up being about 4x4 m on the ground.

Apologies before hand- as this podcast on crypto is hosted by someone who sounds as if he is struggling to put 5 words together (ME). Or just come across as merely coherent. But its my first podcast- The topic is on Elastos- the coming blockchain internet. Put in a good word for Mastodon. wmblockchain.podbean.com/

Girl Loses NASA Internship Over Insult to ‘October Sky’ Legend—He’s Still Helping Her - should have stayed fired imo - gotta have standards. If not enforced, they're not worth anything. Talk about setting the bar low. I wouldn't use this language period.

Message to New Members

Welcome to the Qoto Mastodon instance, its like twitter but better!

Please don't hesitate to Direct Message me or tag me in Toots (what we call tweets here) if you have any questions or even if you just want to chat.

If you are new to Mastodon you may want to check out this official getting started guide: https://github.com/tootsuite/documentation/blob/master/Using-Mastodon/User-guide.md

We are a free speech, no censorship zone. Feel free to talk about whatever you want, say whatever you want, as long as it is legal you wont ever get banned from the server. With that said we do have a few rules: No spam, and no using multiple accounts to circumvent personal bans.

This server isnt a typical mastodon server either. I have personally modified the code on this server to give it several unique features you wont find on other servers.

If you are new to Mastodon here is some useful info.

First off, if your coming from Twitter and you'd prefer an interface that looks exactly like twitter, then just go here and login with your Qoto credential: https://halcyon.qoto.org/ No need to create an account there, your account on this server will work just fine. Just enter your username in the following format @[username]@qoto.org so for me it would be @freemo But personally I think our default skin here is way better.

Basically Mastodon is a decentralized twitter. That means anyone can run a server (like Qoto) that people can sign up to and use just like twitter. The unique part is how the servers talk to each other.

If you want to tag someone on the same server as you then you can just do @user however if you want to specify someone on a different server you can do @user@server. If someone follows you or mentions you on any server on the internet you'll get notified right here. So my full tag is @freemo@qoto.org.

So now a bit about the timelines, there are three (unlike twitter there is just one): Home, Local, Federated.

The Home timeline is just like what you'd expect on twitter, that is, everyone you are following.

The local timeline is any post made by anyone on your local server.

The federated timeline is what is cool. It combines the timeline of everyone on the server into one. This way you can see the posts of everyone that is followed by anyone on the server (assuming the post is public). So this timeline is a close representation of everyone on the internet who has Mastadon (though not really). Moreover we have a bot here that goes around and federates with everyone it can find, so our Federated Feed is rather robust covering thousands of instances.

Only other thing that is unique is listed vs unlisted posts. You have normal privacy settings like on twitter but you also can set a post to be listed or unlisted. If it is listed it acts just as i described. If it is unlisted then it acts just as a normal tweet would but it doesnt show up on local or federated timelines anywhere.

Also this goes without saying, but don't be racist, sexist, hateful, and don't harass people. Its a pretty shitty thing to do, don't be shitty!

The following is the list of QOTO administrators/moderators.
  • @freemo@qoto.org
  • @absolutus@qoto.org
  • @arteteco@qoto.org
  • @Surasanji@qoto.org
  • @hashtaggrammar@qoto.org
Note: The account @QOTO@qoto.org listed as the administrator is NOT an actively monitored account. It was selected so as not to show favoritism among our moderator group, we are a democracy and even our administrators and moderators are held to the same high standards of decency as the rest of the community.
