Use the image editors built in to the article to manipulate images at various stages in the compression pipeline.

Behind the ubiquitous JPEG are layers of algorithms, some which take into account properties of the human visual system 👁️
Learn why some small changes to an images bytes can turn this cat from 😺 to 🤯
The human visual system is more sensitive to sub-sampling in certain encoding channels than others. JPEG takes advantage of this fact to get file sizes down small, while making minimal impact on the appearance of on image

Check out the README for an easter egg that let's you use your own images in the interactive components throughout the article

Not to mention that if this is true (it's almost certainly not, but let's just play along with Cheeto Jesus and his Orange Fantasy World for a moment, shall we?), what Obama told him about DPRK was very, very far from UNCLASSIFIED.

POTUS can declassify and release whatever he wants, but only the mentally unwell would consider telling the world this (if it's true: if) to be wise and helpful to world peace and American national security.

France Inter. 8 janvier 2019. Ça raconte n’importe quoi sur l’application des peines et les journalistes qui n’y comprennent rien ne contredisent jms.

Non, il est faux de dire qu’une peine de 3, 4 ou 6 mois n’est pas EXECUTEE lorsque le condamné ne va pas en prison. #interactive
Chers @ndemorand et @LeaSalame, je ss désolée d’avoir dit un peu brutalement que vs n’y « compreniez rien », ce n’était pas une injure (moi par exemple je ne comprends rien à l’économie, je ne sais tjrs pas ce qu’est le PIB).

Alors je vs en prie, écoutez moi une seconde. #Peines
Juste une seconde parce que le sujet de l’éxecution des peines est récurent, que vous ne parvenez jamais à y répondre parce que vous avez les mêmes idées reçues que vos invités sur le sujet.

On déconstruit ensemble ? 😏

This all started because the #MetPolice & #LBRUT couldn't do their day jobs properly & decided to take the law into their own hands. It started as a small cover up 12 years ago but has turned into British State Persecution.

#Skynews #BBCNews #DailyMail #Guardian #Euronews
My company was raided. It should have been a straightforward matter. But the #MetPolice & #LBRUT forgot to seize my computer & came back to do a 2nd raid. The search warrant didn't permit a second entry, however, #LBRUT entered unlawfully

#Guardian #Telegraph #DailyMail #GMB #UK
Complaints were then made to my MP #VinceCable. He liaised with the #Metpolice & #LBRUT. And then weeks later, the search warrant was completely changed & was passed off as the search warrant executed on the day of the raids.

Objective #art is possible only when somebody has attained to a higher plane of being; it is created by those who have reached the peak. They can see the peak and they can see the valley both. They can see the height, the beauty, the sickness and the ugliness of #humanity.
They can see deep down in the dark valleys. They can manage to create some devices which will help the people who are crawling in the darkness to reach the sunlit peaks. Their art will be just a device for your inner #growth, for #maturity.
Picasso’s pictures are subjective art. Seeing a painting by Picasso … he has not considered you, who are going to see the painting. You are not taken into account at all. He has simply vomited his own madness on the canvas. It is simply a vomit.

Thought I would share some history of our #Press and perhaps some of the ppl behind it so we can understand how it became #FakeNews "The first American press was the partisan press, underwritten and dictated by the political parties."
"The third wave in American journalism—that of the foundation press—may be taking form now thanks to Bay Area billionaires Herbert and Marion Sandler. Waving $10 million that they promise to replenish annually"
"The Sandlers have founded the nonprofit ProPublica to produce investigative journalism. (Usual suspect the John D. and Catherine T. MacArthur Foundation is also chipping in some money to the ProPublica kitty, as are the Atlantic Philanthropies and the JEHT Foundation.)"
