«Comment osez-vous? Vous avez volé mes rêves et mon enfance!»

Dans un discours furieux à l’ONU, la jeune Suédoise Greta Thunberg a réprimandé les dirigeants de la planète pour leur inaction contre le changement climatique, au début d’un sommet consacré à ce sujet à New York.

«Je ne devrais pas être là, je devrais être à l’école, de l’autre côté de l’océan», a lancé Greta Thunberg, la voix tremblante, lisant un texte préparé.

«Comment osez-vous? Vous avez volé mes rêves et mon enfance avec vos paroles creuses», a-t-elle poursuivi, ajoutant ensuite: «Mais les jeunes commencent à comprendre votre trahison».

Apple’s next macOS is here

Apple’s next macOS is here

The new goodies make macOS better than ever

With macOS Catalina, Apple says goodbye to iTunes and hello to the Music app. An official Apple Podcasts app is also available on the free update.

What’s new with macOS 10.15 Catalina?

There are dozens of new features on macOS 10.15. Some are bigger than others, of course.

Three new apps to replace iTunes

Apple has split iTunes into three fresh apps and retired the iTunes name, at least as an app. The apps are: Music, Apple Podcasts, and Apple TV.

Music is a lot like iTunes and even more like the Music app on iOS 13. It offers syncing capabilities for those who still like to sync iPhone and iPad with Mac. For those who love buying music, there’s a store built into the app. That store is called … the iTunes Store!

Apple Podcasts offers an interesting search feature that uses machine learning to help you find a podcast you heard about but forget its name by title, topic, guest, host, and more. Apple says there are now over 700,000 podcasts available.

Finally, the new Apple TV app supports 4K and Dolby Atmos-supported films for the first time on Mac. It looks similar to the iOS version of the Apple TV app.

All three apps — Music, Apple Podcasts, and Apple TV — sync your content through iCloud across your devices. Or sync it from each of the apps if you prefer using a cable.

Updated Apps

Existing Mac apps like Reminders got minor updates in macOS Catalina.

In Notes, there’s a new gallery view that displays your notes as visual thumbnails, which makes it easier to find specific content. There’s also the ability to share notes or entire folders as view-only. With new shared folders, you can collaborate on a folder level with ease. Look for more powerful search functionality as well.

Reminders is completely new in macOS Catalina and includes a new design and more powerful features. These include enhanced Siri intelligence, the ability to add attachments, new edit buttons, and more.

In the Photos app, you’ll now find a new Photos tab, larger photo previews, day, month, and year organization, and auto-playing of Live Photos and videos.

Sidecar with iPad

With Sidecar, you can use your iPad as a second display for Mac! This feature works wirelessly and wired. Sidecar also lets you use the same Multi-Touch gestures with your Mac that you do with your iPad. Draw and sketch are also supported.

The surprise news here is just how many third-party apps already supporting Sidecar on day one. These include Adobe Illustrator, Affinity Designer and Photo, CorelDRAW, Sketch, and many more.

Screen Time for Mac

In macOS Catalina, Screen Time makes the leap from iOS. Among the features is the ability to combine limits based on app categories, specific apps, or websites. Screen Time for macOS also lets you control who your child can communicate with and who can communicate with them. There’s also One More Minute, a simple way to give your children 60 more seconds before things go dark.

Accessibility

On macOS Catalina, there’s Voice Control, a new way to fully control your Mac, iPadOS, and iOS devices with your voice. It’s just one of many new accessibility features in macOS Catalina.

Safari improvements

The native web browser for Mac picks up a few new features in macOS Catalina, beginning with the start page. Joining links to your favorites and frequently visited websites, this page now includes Siri suggestions. These links are based on your overall browsing history, recently visited sites, bookmarks, and more. Safari on macOS Catalina also offers weak password warnings, which pops up when you attempt to create a new password. When doing so, it will help you replace the password with a stronger one. Safari also includes Picture in Picture (PiP) from the tab audio button for the first time.

Find My app

Find My iPhone and Find My Friends have been merged on both Mac, iPhone, and iPad as Find My. The combined app lets you locate the people and devices that are important to you.

Activation Lock

Available on all Macs with a T2 Security Chip, Activation Lock allows you to erase and deactivate your Mac in the event that it’s stolen. It’s similar to a feature already available on iPhone and iPad.

Screen Time for Mac

One year after it arrived on iOS, ScreenTime is coming to macOS too. The controls allow you to keep track of your usage on Mac and also restrict the content that’s available. You can also use ScreenTime to turn off features at certain times of the day.

Approve with Apple Watch

You can soon double-click the side button of your Apple Watch to authenticate on your Mac. In doing so, you can unlock a locked note, approve app installations, and view your passwords in Safari preferences without having to enter one.

Sign In with Apple

With Sign In with Apple, in iOS 13, iPadOS 13, and macOS Catalina, you can use an encrypted "burner" email address (if you will) to sign up for and into services that support third-party sign-on services online. It’s a single sign-on service, similar to the way Google and Facebook allow you to use your account credentials to sign up for and sign in to apps and services.

Mail’s new tools

The native email app on macOS can now block all mail from specified senders. From there, the emails are automatically sent to your trash folder. The Mail app also (finally) lets you unsubscribe to emails — just like you can do in iPhone.

Dedicated system volume

Your system files on macOS are now kept in a dedicated, read-only volume that’s separated from your other data. This makes it harder for you to overwrite critical files accidentally.

When can I download the official version of macOS Catalina?

macOS Catalina is a free update available in the Mac App Store.

My Mac is old, can I upgrade to macOS Catalina?

The latest Mac operating system will run on the following devices:

  • MacBook (2015 or newer)
  • MacBook Air (2012 or newer)
  • MacBook Pro (2012 or newer)
  • Mac mini (2012 or newer)
  • iMac (2012 or newer)
  • iMac Pro (2017 or newer)
  • Mac Pro (2013 or newer)

Lots to see

Which macOS Catalina features are you most excited about seeing?

How to Use Vibrant Colors in Photography with Great Success

How to Use Vibrant Colors in Photography with Great Success

The post How to Use Vibrant Colors in Photography with Great Success appeared first on Digital Photography School. It was authored by Nisha Ramroop.

How to Use Vibrant Colors in Photography with Great Success

Your camera is capable of capturing intense, true color that is almost everywhere you look. So how hard could it be? Answer: It is actually quite easy to capture color. However, you need to practice a little more awareness when it comes to creating images with that extra “oomph.” Here are a few tips to help you capture vibrant colors in photography.

1. Keep it simple/details

As with other types of photography, simplicity is an art on its own. While details are can be essential too, sometimes scaling back on the amount of details is required. Thus, when working with vibrant colors in photography, your story may have more impact when you include only the key elements as opposed to having too much going on.

How to Use Vibrant Colors in Photography with Great Success

You can achieve simplicity in different ways. The first is by minimizing the number of colors in the frame. Yes, there are instances when many colors work well together in an image, but at other times it gets confusing. You need to direct your viewer’s eyes. Another way to keep it simple is to avoid too many details in your composition. It has the same effect as too many colors. When working with vibrant colors, simple works better.

2. Experiment with color combinations

Starting small is usually better with bolder colors. You can focus on one main color and build from there. When you start adding other colors in, determine if they work well together. Fortunately, you do not have to reinvent the color wheel and have tried-and-true color harmonies to use to your advantage.

How to Use Vibrant Colors in Photography with Great Success

Color harmony is a combination that is visually appealing to the eyes. Some of the options include complementary colors (those directly opposite each other on the wheel) and analogous color (those next to each other).

Both of these harmonies exist in the natural world. A sunset of oranges and blues is an example of complementary colors. Whereas a green tree against the midday blue sky is more along the lines of analogous color. When you are working with color combinations, spend the time to make the final image pleasing to the eyes.

3. Make colors stand out/playoff

Your scene may be full of color, vibrant and busy. If this is what you want to portray, then all is well. On the other hand, what if there is a subject in that chaos that you want to isolate? You can use color to make that happen. To do so, one of your options is to desaturate/tone down the colors that are not contributing to your subject’s story.

How to Use Vibrant Colors in Photography with Great Success

Another is putting a bright color against a dull one to help it to stand out more. Also, adjusting the hue and lightness of the colors next to your main color can help it pop.

Here are a few easy ways for you to help your colors play off each other:

White Balance

Pay attention to your use of white balance when working with bold and strong colors. Your camera has several white balance options to deal with different lighting situations (Shade, Cloudy, Fluorescent, etc.). Each of these affects the overall color of your image. They either move your color to the warmer side (by adding yellow) or to the cooler side (by adding blue). Thus, white balance can enhance your colors or change the hue altogether.

Note: If you do not want your colors to end up looking too blue or yellow, you have the option of manually adjusting your white balance color temperature.

Saturation

By default, Saturation is used to enhance the color intensity of every color in an image. However, you can use editing software and use Saturation selectively. When trying to make colors play off each other, you can increase the intensity of one color while desaturating other colors in the scene.

Vibrance vs Saturation (the same level applied)

Vibrancy

When you change the Vibrance in an image, it is a little more specific than Saturation. Vibrance only adjusts the intensity of the duller colors in your image. When playing off colors, this tool can be very effective.

Conclusion

When working with vibrant colors, be aware of your palette. Keep your compositions simple by minimizing the number of colors and details in your image. Work with the color wheel and learn about the various harmonies that exist. When you pay attention to all the colors in your image, you get a better sense of how they work together. You also understand the way each color affects and plays off the other. Most of all, have fun experimenting while you learn about color!

Comment envoyer sa position GPS rapidement aux secours ? (Affaire Simon Gautier)

Comment envoyer sa position GPS rapidement aux secours ? (Affaire Simon Gautier)

Simon Gautier, ce jeune français installé en Italie, et retrouvé décédé ce week-end suite à une randonnée qui a mal tourné, a remis sur la table une question centrale autour du positionnement des victimes.

Dans le cas du jeune homme, ce dernier était parvenu, malgré son accident, à appeler les secours avec son téléphone portable. Malheureusement, il semble que ce dernier n’ait pas réussi à envoyer un positionnement précis au moment de l’appel. Les autorités ont dû faire appel à la géolocalisation via les antennes relais, ce qui engendre un périmètre de recherche souvent trop étendu pour intervenir à temps, surtout si la zone est peu habitée.

Sur iOS, il existe un moyen simple de connaitre sa position GPS. Il n’y a pas besoin de réseau de données, il suffit d’ouvrir l’app « Boussole » présente par défaut, et de lire les coordonnées inscrites sur la partie basse :

C’est très pratique, car votre téléphone peut utiliser n’importe quel réseau de n’importe quel opérateur pour appeler les secours vocalement (112), et vous n’avez pas besoin de 3G/4G/5G pour transférer l’information. Le seul impératif est de pouvoir capter le GPS, et donc, d’avoir le ciel en visuel. Il faut aussi pouvoir lancer une app, ce qui n’est pas toujours facile suivant la gravité des blessures.

Voilà pourquoi un système créé en Europe et appelé Advanced Mobile Location (AML) permet justement d’utiliser la puce GPS et les SMS pour envoyer automatiquement vos coordonnées aux secours en cas d’appel. Apple était à la traine face à Android et iOS n’est compatible que depuis 2018 (iOS 11.3). Il faut également que les pays prennent en charge le service (ce qui est assez coûteux), mais il s’agit désormais d’une obligatoire européenne. L’Italie comme la France n’ont pas encore d’AML pleinement actif (des phases de test sont a priori en cours), mais le système devrait être enfin déployée d’ici la fin de l’année. « La France fait partie d’une deuxième phase de développement et je pense qu’elle va mettre en place l’AML d’ici à la fin de l’année. D’autres pays, comme l’Estonie, la Finlande ou la Suède l’ont réalisé sans fonds européens. Aujourd’hui, un tiers des pays européens ont l’AML et un autre tiers est en train d’y travailler. » a déclaré Jérôme Pâris, directeur de l’ONG European Emergency Number Association (EENA) à LaCroix.

Le complot mondial sur la conquête spatiale et tous ses secrets enfin révélés !

Le complot mondial sur la conquête spatiale et tous ses secrets enfin révélés !

Il n’y a pas que la politique, les actes de terrorisme ou la vie dissolue des blogueurs et youtubeurs qui sont le terreau de tous les complots. Non, non, il y a aussi l’espace et ses innombrables merveilles.

J’ai d’ailleurs déjà été confronté, suite à des articles sur l’espace, à des gens qui me soutenaient que l’Homme n’avait jamais marché sur la Lune ou qu’il n’y avait pas de robots sur Mars, voire qu’au contraire, ça faisait super longtemps que les Américains ont une base secrète sur Mars.

M’enfin, globalement, il y a souvent les mêmes questions qui reviennent, du genre pourquoi les fusées ne montent pas droit, pourquoi n’y a-t-il aucune photo de la terre vue de la lune, pourquoi les astronautes ne jure-t-il pas sur la bible, pourquoi ne sommes nous pas retournés sur la lune en 50 ans ou encore pourquoi n’y a-t-il pas de poussière sur les pieds du module lunaire…et j’en passe.

La bonne nouvelle, c’est que le youtubeur Defakator a passé en revue toutes ces questions et plus encore et cela vous permettra de rétablir la vérité dans les mares de complotistes.

Youpi !
