Marcel Breaks Time, Converts Documents to Ebooks and More on Cooking with Linux (without a Net)

Today on Cooking with Linux (without a Net), I do my best to break time, see what I can do about converting some difficult documents to ebooks, and show off another distribution you've never heard of. Hint: it's named after a lizard. Oh, and there's a super secret secret embedded somewhere in the video. Oooh! Aaah! For the record, this is a prerecorded video of a live show, the Tuesday live Linux Journal show, to be exact, where I do some live Linuxy and open-source stuff, live, on camera, and without the benefit of post video editing, therefore providing a high probability of falling flat on my face.

An Average Earth Day Used To Be Less Than 19 Hours Long

Slashdot - Wed, 06/06/2018 - 11:20
Scientists have determined that some 1.4 billion years ago, an Earth day -- that is, a full rotation around its axis -- took 18 hours and 41 minutes, rather than the familiar 24 hours. The Guardian reports: According to fresh calculations, a day on Earth was a full five hours and fifteen minutes shorter a billion or so years ago, well before complex life spread around the planet. Scientists used a combination of astronomical theory and geochemical signatures buried in ancient rocks to show that 1.4bn years ago the Earth turned a full revolution on its axis every 18 hours and 41 minutes. The number means that, on average, the length of the day on Earth has grown by approximately one 74 thousandth of a second per year since Precambrian times, a trend that is expected to continue for millions, if not billions, of years more.

Microsoft Sinks Data Centre Off Orkney To Test Energy Efficiency

Slashdot - Wed, 06/06/2018 - 10:40
An anonymous reader writes: Microsoft has sunk a data centre in the sea off Orkney to investigate whether it can boost energy efficiency. The data centre, a white cylinder containing computers, could sit on the sea floor for up to five years. An undersea cable brings the data centre power and takes its data to the shore and the wider internet -- but if the computers onboard break, they cannot be repaired. The operation to sink the Orkney data centre has been an expensive multinational affair. The cylinder was built in France by a shipbuilding company, Naval, loaded with its servers and then sailed from Brittany to Stromness in Orkney. There, another partner, the European Marine Energy Centre (EMEC), provided help including the undersea cable linking the centre to the shore. "This is a crazy experiment that I hope will turn into reality" said Ben Cutler, who is in charge of what Microsoft has dubbed Project Natick. "But this is a research project right now -- and one reason we do different types of research into data centres is to learn what makes sense before we decide to take it to a larger scale."

Company Takes Over Well-Known OSS Developer's Name Because the Domain Was Free

Slashdot - Wed, 06/06/2018 - 10:00
New submitter Fatalis writes: Substack is a venture capital funded startup for subscription-based newsletters, and it admittedly chose its name following the advice from a Paul Graham (co-founder of Y Combinator) article to prefer names not registered in the .com zone. The same name has also been the user handle for a prolific open-source developer who now finds themselves competing for recognition in the tech space with a capital backed company. The lesson seems to be for developers to protect their personal brand by registering a domain name with the .com extension due to it being perceived as the default.

Getting started with Buildah

LXer - Wed, 06/06/2018 - 08:24
Buildah is a command-line tool for building Open Container Initiative-compatible (that means Docker- and Kubernetes-compatible, too) images quickly and easily. It can act as a drop-in replacement for the Docker daemon’s docker build command (i.e., building images with a traditional Dockerfile) but is flexible enough to allow you to build images with whatever tools you prefer to use.

Streamlio Announces Apache Pulsar 2.0, Red Hat Launches Buildah 1.0, Firefox Experimenting with Two New Projects and More

Linux Journal - Wed, 06/06/2018 - 08:03

News briefs for June 6, 2018.

Streamlio, "the intelligent platform for fast data", today announces the availability of Apache Pulsar 2.0, which is an "open-source distributed pub-sub messaging system originally created at Yahoo and now part of the Apache Software Foundation". This release "adds new capabilities to Apache Pulsar that support easy development and deployment of modern data-driven applications and demonstrate the maturity and enterprise-class capabilities of Pulsar while delivering significantly better performance, scalability and durability than older messaging platforms such as Apache Kafka, as verified in real-world OpenMessaging benchmark tests." For more info, see the Streamlio blog post. Streamlio will be demonstrating the new functionality in Pulsar 2.0 at booth S8 at the upcoming Data Works Summit in San Jose, CA, June 17–21.

Red Hat announced the launch of Buildah 1.0 today. Buildah is a command-line utility that "provides only the basic requirements needed to create or modify Linux container images making it easier to integrate into existing application build pipelines". The container images Buildah builds are "OCI-compliant and can even be built using Dockerfiles. Buildah is a distillation of container development to the bare necessities, designed to help IT teams to limit complexity on critical systems and streamline ownership and security workflows."

Mozilla's Firefox is launching two new projects, Firefox Color and Side View, through its Test Pilot program. According to the TechCrunch article, Firefox Color is basically a theme editor that lets you do things like choose colors in your browser and set textures for the background. Side View lets you "use your widescreen monitor and display two tabs side-by-side inside the browser without having to open a second Firefox window." Both are available here, if you'd like to try them.

FOSS Project Spotlight: WallpaperDownloader

Linux Journal - Wed, 06/06/2018 - 07:08
by Eloy Garcia Almaden

Are you bored with the look of your desktop? Are the wallpapers that come with your distro enough for you? WallpaperDownloader is a graphical application that will help you customize your desktop and find wallpapers automatically.

WallpaperDownloader allows you to download, manage and change your favorite wallpapers from the internet. It is open source (GPL3) and totally free. Simply type in some keywords, enable the providers to include (up to six), select the download policy, and WallpaperDownloader does the rest.

WallpaperDownloader's main features include:

  • Users can select keywords for matching desired wallpapers across different sources.
  • Currently, six providers are implemented for searching.
  • Different download policies are implemented.
  • Preferred resolution for the search can be defined.
  • The maximum size for downloaded directories can be changed.
  • Wallpapers can be classified as favorites or not favorites.
  • Favorite wallpapers can be moved to another location with a single click. This is very nice if you have a directory for storing images (for example, a directory in Dropbox).
  • WallpaperDownloader is translated into English and Spanish so far.
  • It implements an automated "changer" for changing the wallpaper randomly every X minutes. You can define as many directories as you want.
  • A system tray icon is implemented (for desktop environments that support this feature) with quick actions.
