I thought it'd help to be descriptive.

A long time ago I have used ffmpeg to transition one jpg to another jpg as a gif animiation. I will see about coming back and editing the comment with a reference.

The answer on this page is where I'd start: https://stackoverflow.com/questions/71178068/video-morph-between-two-images-ffmpeg-minterpolate

But I don't have time to delve into it now. I can see about help if you reply, but it won't be for a few days.

Thankyou, i'll update the post.

This inspired me to do some photoshopping.

I don't know, but one of the other comments said they're dead pixels, a part of the camera has failed over time.

GPG uses a public key encryption algorithms. Widely known encryption uses symmetric encryption, ie the same passphrase is used to encrypt and decrypt.

Public key encryption algorithms have two keys, a public key and a private key. They are created as a pair.

When someone creates the pair, they can safely widely publish their public key which is essential to encrypt a message to the receiver. But a different key is needed to decrypt the message (the private key).

They can also be used in reverse. A person with a private key can sign a message saying they created a document and it has this hash. We can use their public key to confirm the message they send out has not been altered.

A hash is a computer algorithm which examines a files and creates a short pattern of characters. If the file is changed then the hash of the file also changes.

As a example, If we had a written letter, a very simple hash could be to assign a the number 1, b 2,, c 3 etc and full stop could be 27, comma 28, and the digits 0-9 29-38. For every character we keep adding the assigned numbes and keep a total. When we get to the end, we take the last 3 digits and have a number between 000 and 999. (Technically this is more a checksum than a hash, but please just go with it. A hash like MD5 or SHA256 is complex and has ways to detect if the message contents was shuffled that the described hash wouldn't)

Continuing the example, I may receive a letter from a relative who asked me for some money or something. If I wasnt sure if it was real or not, I could calculate the hash and call the relative and confirm the hash.

But back to your example, there might be a press release from the presidents account saying something like

"Dear constituents, Please find attached a link to download the lastest video update from the presidents. It can be downloaded at URL, and it has a SHA256 hash of abcd12345 Signed President GPGSignature for president@example is 'ajfuebslch' " Once we download the file, we can use SHA to generate the has of the file we downloaded and GPG to confirm the signature of the message we received matches the text of the message we received.

If we didn't have GPG and the Public key of the presidents account, an attacker who makes deep fakes could send us spam purporting to be from them and include in the message the correct hash for their deepfaked video.

I dont quite fully understand how public key encryption works, but the GPG signature allows us to confirm the message was sent by whoever has the matching private key to the public key we've got and the hash lets us confirm the file we downloaded is the same as the video the semder wants us to receive.

About a week ago I contacted them about something and they got back to me pretty fast

Edit: although I can't give a source, I understand that if a post gets enough reports, site admin can see it and not just community mods.

A wallaby is smaller, i'd say about 2/3rds typically. There can be some absolute unit Kangaroos, about as tall as me and there are videos of humans and kangaroos punching on, and the roo's will punch on with other roos too. A wallaby might come up to my waist.

I can tell the differences by looking at the faces. The kangaroos nose seems longer and wider where the wallaby's is shaped to a point. i dont remember seeing any around canberra

Kangaroos usually travel in a mob of about 5-15 with a dominant male and lots of females and joeys but you can catch them alone. They'll usually hop along if you get too close for comfort.

Here's a close up of a wallaby

Nah bro, she's a distant relo. After her town got harassed by a bunch of Lazer kiwis from the South, she got on the blower saying she's comin' over and they need to summon some of Australia's greatest warriors.

I was chuffed, but she explained it wasn't me and we had to get some Emu plumes. Once we have enough for her to summon a mob, she'll disappear from here faster than Harold Holt.

Dodads and thingamajimmys!, Bonza!!. And I'll grab some Jandals and a Chilly Bin for my Cuz. She's been after a new home for her Ice Elemental. If I shout if for her, she should let me keep a few tinnies in there too.

In Aus, we have 000, triple zero. I think 112 works here too, might just be mobiles though. It used to be triple oh, but some people saw the keypads had letters on them and dialled 777 or whatever number o was on.

I've probably seen too much American media. I'm happy for any, even 0118 999 881 999 119 725 ... 3 but it might be a bit hard to learn.

If you're having a drink like coffee or hot chocolate, a "Tim Tam Slam" is where you bite both end of the biscuit and use it like a straw.

As another avenue to the report button, could Lemmy world have a new community LemmyWorldSupport_911 where anyone can post and it's monitored by moderators or admins and they can promptly react?. (911 =American number for emergency services)

As part of the community rules, posting for stuff that doesn't warrant a 911 reaction could result an penalties for anyone looking to "prank" it or abuse it's intended purpose.

Some small communities only have one mod and that mod has to sleep.

Probably. If you really want to reverse the invisibility spell, we could dust you with some of the coconut and we should be able to see your outline.

If you want to stay invisible and it turns you back, it's another trip to Grandma's, so win/win.

What about a Tim Tam? Lamington?

Smiles and hands you a Vegemite sandwich.

Yeah, I'm trying to help grow things here and made it more appealing. There's a magnet on my whiteboard "be the reason someone smiles today."

Although this account is relatively new, I've been hanging around since some app developers decided to move to support Lemmy.

Im not 100% sure, but am confident its the one north of Cordes road, north of Kingscote. It wasn't the main Kingscote jetty.

It took a while, but i got a picture of a Myna, https://lemmy.world/post/11514077 It's not the best, but shows the differences, i couldnt really tell which would be bigger if they sat side by side.

The boat was like one that could tow a water-skier and we were going pretty fast.

I think like how ducks fly in a V shape to travel efficiently, the dolphin could "ride" along the wake of the boat

Id say the dolphins liked riding along with the boat as it's wake could let them swim faster like someone on a bike could ride faster if they rode downhill.
