VideoLAN Announces Dav1d, a New Libre and Open Source AV1 Decoder

Jean-Baptiste Kempf, president of VideoLan and developer of VLC media player, made the following announced Monday: AV1 is a new video codec by the Alliance for Open Media, composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft,…). AV1 has the potential to be up to 20% better than the HEVC codec, but the patents license is totally free, while HEVC patents licenses are insanely high and very confusing. The reference decoder for AV1 is great, but it’s a research codebase, so it has a lot to improve. Therefore, the VideoLAN, VLC and FFmpeg communities have started to work on a new decoder, sponsored by the Alliance of Open Media. The goal of this new decoder is: be small, be as fast as possible, be very cross-platform, correctly threaded, libre and (actually) Open Source. Without further due, the code: https://code.videolan.org/videolan/dav1d Recommended: A talk during VDD 2018 conference

Microsoft re-open-sources early versions of MS-DOS on GitHub

Back in 2014, Microsoft gave the source code for MS-DOS 1.25 and MS-DOS 2.0 to the Computer History Museum. Now — in a move it describes as “re-open-sourcing” — the company has pushed the code to GitHub for all to see. Dating from mid-1983, the source code may moisten the eyes of anyone who remembers the days of text-based operating systems, and it gives an interesting glimpse into the world of software development a few decades ago.

Introducing dav1d: a new AV1 decoder

Introducing dav1d

AV1 is a new video codec by the Alliance for Open Media, composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft,…).

AV1 has the potential to be up to 20% better than the HEVC codec, but the patents license is totally free, while HEVC patents licenses are insanely high and very confusing.

The reference decoder for AV1 is great, but it’s a research codebase, so it has a lot to improve.

Therefore, the VideoLAN, VLC and FFmpeg communities have started to work on a new decoder, sponsored by the Alliance of Open Media.

The goal of this new decoder is:
be small,
be as fast as possible,
be very cross-platform,
correctly threaded,
libre and (actually) Open Source.

Name

dav1d is called dav1d, because Dav1d is an AV1 Decoder

(Yes, that is a recursive acronym, no need to tell us…)

Use of the Internet and Smartphones is No Longer on the Rise in America

For years, the number of Americans who have reported using the internet, social media, and smartphones has been on a meteoric rise. But that rate has slowed to a near-stall. From a report: New data published this week by the Pew Research Center show that, since 2016, that number has plateaued, indicating those technologies have reached a saturation point among many groups of people. The percentage of Americans using smartphones (77%), the internet (88% to 89%), and social media (69%) has remained virtually unchanged during the last two years. “Put simply, in some instances there just aren’t many non-users left,” the report states. More than 90% of adults younger than 50 report they use the internet or own a smartphone. This number squares with some of the trends noticed earlier this year by Gartner, a global research firm. The fourth quarter of 2017 marked the first time since 2004 that

Apple’s ‘Everyone Can Create’ curriculum launches on Apple Books

Fist announced at Apple’s education event in Chicago, the company today launched its new “Everyone Can Create” curriculum on Apple Books. The curriculum joins Apple’s “Everyone Can Code” initiative by offering teachers a way to integrate drawing, music, filmmaking and photography into their classroom lesson plans.
Specifically, “Everyone Can Create” is designed to take advantage of Apple’s new 9.7-inch iPad and Apple Pencil, also introduced at the company’s event this March in Chicago. Before its introduction, only Apple’s expensive iPad Pro model offered Pencil support. The new iPad, however, is just $299 for schools, like the prior 9.7-inch device. (Or it’s $329 for consumers.)
The curriculum itself was built by Apple in collaboration with teachers and educators, and works to alongside Apple’s built-in apps like GarageBand, iMovie, Clips, and others. It’s been in preview since the news of its arrival earlier this year, with educators in over 350 schools worldwide giving it
