I reckon a Pelican would easily be able to get a skateboard rolling. I’m just now sure the best steps to proceed testing it.

I’d try a skateboard at the top of a hill and see about getting a cockatoo to somehow get the board to roll under it’s own propulsion so it can sit back and enjoy a ride down a hill. That’d be the way I’d try if I wanted the bird to do it repeatedly.

My guess is with the protests that some of the top content creators moved away and never came back.

I remember sorting by hot once gave a wide variety of things and now it seems to be more drama posts like AITA posts.

Although it feels like I’m still following an ex, There was one place over there I used to visit a lot and I believe if you took a snapshot of the top ten posts of a random day few years ago and today, they’d be very different. Today’s seems to be a group picking up a trend and running with it and before it was more original content. I remember going there because I knew there’d be something new I’d likely laugh at or be amused by and now it feels heavily recycled.

The subscriber count is still way up, but I’d you look at the online/active user count, it feels like its around 10% it was off recent highs.

It felt like the sub had a ship of thecleus moment where it seemed to just be growing, but was also losing people until the group changed but the name was the same.

Someone else said the new reddit gold allows people to receive real money* if people gild their posts (by spending real money) * receiver must be in certain countries.

I saw a post recently on a wholesome memes page where someone tagged repost sleuth bot and someone else commented that todays post was literally a copy of the third top voted post of all time. It was.

I also remember that bot support got affected and this led to a spam detector bot being moved from active development to sunset mode where it was still supported but not actively enhanced.

Edit: my comment isn’t about exactly the same thing, but …

Some new camera tech might be opening a can of worms about whether what’s pictured can be taken literally.

There was a story late last year of a woman trying on a wedding dress in front of two mirrors and someone snapped a photo.

When they looked at it, the reflection on the left mirror had a different pose to the reflection on The right mirror.

And this cast doubt on what exactly was going on the moment the shutter was pressed.

It looks like the camera had one of the stitch together the best photo of the people pictured (e.g. don’t show shots of people blinking etc) and it treated the mirror images as different people.

I can’t help directly, but the people at https://lemmy.world/c/techsupport mighr be able to.

And when it learns something new, the response will be “Holy Hell”.

Lemmy.world is still running Lemmy 0.18.x and will soon upgrade to 0.19.x and 0.19 has scaled sorting.

Improved Post Ranking There is a new scaled sort which takes into account the number of active users in a community, and boosts posts from less-active communities to the top. Additionally there is a new controversial sort which brings posts and comments to the top that have similar amounts of upvotes and downvotes

World. Why? “Hello World”.

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.

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.

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.
