Hasard du calendrier, la ministre de la Transition écologique, Elisabeth Borne, et le président de l’Autorité de sûreté nucléaire (ASN), Bernard Doroszczuk, ont arrêté le 21 février, la décision consécutive au débat public concernant la cinquième édition du Plan national de gestion des matières et des déchets radioactifs (#PNGMDR), le jour même de l’arrêt du réacteur n°1 de la centrale nucléaire de Fessenheim. […] Les attentes relatives à l’association des citoyens sur ces sujets clivants ont trouvé une résonance forte dans le #débat_public, qui s’est déroulé pendant cinq mois, et dont le bilan a été présenté le 25 novembre dernier par la Commission nationale du débat public et la Commission particulière du débat public.

A MAJOR LIABILITY: Illegal logging in Papua New Guinea threatens China’s timber sector and global reputation | Global Witness
▻https://www.globalwitness.org/en-gb/campaigns/forests/major-liability-illegal-logging-papua-new-guinea-threatens-chinas-tim

https://www.globalwitness.org/media/images/Logs_piled_next_to_road_in_East_New_Britain_P.width-1024.jpg

In 2016, PNG provided 29% of China’s tropical log imports, making it the country’s single largest supplier. But our investigation reveals how a large number of logging operations in Papua New Guinea (#PNG) violate the law despite holding government-issued permits.

China is the world’s largest consumer and manufacturer of wood and wood products. Yet it has no regulation to keep illegal timber from entering its borders.

Super Tiny Website Logos in SVG
▻https://shkspr.mobi/blog/2017/11/super-tiny-website-logos-in-svg
▻https://github.com/edent/SuperTinyIcons

You may not realise it, but #bandwidth is expensive. It costs you time, money, and battery power whenever you download a file larger than it needs to be.

That’s why I’ve become a little bit obsessed with #SVG - Scalable Vector Graphics. They’re the closest thing to magic that the web has when it comes to image compression. Let me show you what I mean.

This is the standard Twitter #Logo. It’s 512 * 512 pixels and, even with hefty #PNG compression, weighs in at around 20KB.

Here’s the same logo rendered as an SVG. Because it is a vector graphic it can be magnified infinitely without any loss of fidelity.

The uncompressed SVG is a mere 397 Bytes. Not a #typo. You could fit over 3,000 of these images on a floppy disk.

That’s why I have released SuperTinyIcons on GitHub. Eighty of the web’s most popular logos - each image is under 1KB.

Optimiser les images et réduire leur poids : formats, outils et RWD

▻https://blog.dareboost.com/fr/2017/10/optimiser-les-images-et-reduire-leur-poids-formats-outils-et-rwd

Au moment de l’enregistrement en JPEG, la plupart des logiciels demandent quelle qualité conserver, car il s’agit d’un format d’encodage avec pertes. En choisissant une qualité inférieure à 100%, il est ainsi possible d’économiser de précieux octets en modifiant uniquement certains points de l’image. Essayons avec notre image, en qualité 80%. Le résultat est très intéressant avec un gain de poids de plus de 50%, alors que seuls quelques points de l’image ont été modifiés en profondeur.

Aside, I’m just realizing that the illustrations are inline base64-encoded #PNG I didn’t know one could just <img src='https://seenthis.net/data:image/png;base64,whatever'> - one can completely self-enclose an #HTML page with its images !

By the way, these sets all have the same mean, median and variance. Lesson: Always visualize !

pngcheck Home Page
►http://www.libpng.org/pub/png/apps/pngcheck.html

pngcheck verifies the integrity of PNG, JNG and MNG files (by checking the internal 32-bit CRCs [checksums] and decompressing the image data); it can optionally dump almost all of the chunk-level information in the image in human-readable form. For example, it can be used to print the basic statistics about an image (dimensions, bit depth, etc.); to list the color and transparency info in its palette (assuming it has one); or to extract the embedded text annotations. This is a command-line program with batch capabilities.
