Mysterious new product to be announced at London Show the day before London show

The content below is taken from the original (Mysterious new product to be announced at London Show the day before London show), to continue reading please visit the site. Remember to respect the Author & Copyright.

In a surprise announcement, ROOL have revealed the existence of "Titanium", a new RISC OS machine based around a dual-core Cortex-A15 SoC. No – it’s not CJE’s dual-core Cortex A15 IGEPv5 machine – it’s an entirely new board design produced by Elesar Limited, and utilising TI’s 1.5GHz AM5728 (a cousin of the also-1.5GHz TI OMAP5 used in the IGEPv5). And unlike the IGEPv5 or the Wandboard (as used in R-Comp’s ARMX6), which are technically meant to be for embedded or developer/prototyping markets, the Titanium board seems to be aimed squarely at the desktop PC and server markets – it utilises the standard ATX form factor and power connector, has dual DVI video output, dual gigabit Ethernet, four SATA ports, eight USB 2 ports, and even two PCI-E slots.

These Bluetooth lights turn your bike wheels into turn signals

Safety lights are one of the most important pieces of bicycle equipment, especially if you ride at night or in low-visibility weather conditions. Most look the same — a large, forward-facing beam under your handlebars and a slim row of red LEDs under the saddle. But Revolights are a little different. For years now, the company has been experimenting with lights that attach directly to your wheels and, by constantly analysing your speed, illuminate at just the right moment to create two arcs of light. The new Eclipse, which it’s pitching on Indiegogo, is its most ambitious set to date. For starters, there’s now a rechargeable "snap-in" battery which removes the awkward, dangling cables from before. The Eclipse+ version is also Bluetooth-enabled, meaning you can track your rides and monitor battery life from your smartphone, as well as trigger turn signals — a full, flashing ring of lights on one side — through a control pad on the handlebars, an app, or by gesturing with a smartwatch.

ARM’s latest graphics core will speed up your smartwatch

The content below is taken from the original (ARM’s latest graphics core will speed up your smartwatch), to continue reading please visit the site. Remember to respect the Author & Copyright.

Samsung Gear S2

Let’s be blunt: the graphics in most smartwatches suck. They’re frequently limited to basic effects, and you’ll sometimes see the kind of stuttering that has long-since disappeared on your smartphone. ARM aims to fix that, however. It’s launching the Mali-470, a mobile graphics core that’s virtually tailor-made for smartwatches, the internet of things and anything else where battery life is the top priority. The GPU supports the flashy per-pixel visual effects you see on modern phones (OpenGL ES 2.0, to be exact), but it uses half as much power as the long-serving Mali-400 even as it runs faster– you could see lively 3D animations that don’t kill your watch within a few hours.

ARM hasn’t named customers for the Mali-470, so it’s not yet clear just who’s using it in their processors. You’ll have to wait a while to use it, at any rate — ARM doesn’t expect the core to reach real, shipping products until late 2016. When it does, though, it could help usher in a new generation of wearables and smart appliances whose graphics don’t feel like throwbacks.

Well, on its American birth certificate at least. Yep, to the groans of middle-aged gamers everywhere, it’s been three decades since Nintendo’s home console first landed: 18th October 1985. Arguably the advent of console gaming, the Nintendo Entertainment System arrived with 17 games, including Mario Bros., and other not-so-much memorable titles like Hogan’s Alley (not the wrestler) and Stack Up — all in often ridiculous box art we’ve already covered in detail. It had a rich life and to celebrate we’ve embedded a video that includes every NES title screen. You’ve got three hours and a box of Kleenex, right? And if you’re still nostalgic, there’s always that aluminum model.

What You Need to Know From the Developer’s List

Success Bot Says

  • ttx: Another OpenStack Release!
  • With help of jesusaurus, the infra team has deployed Kibana 3. First steps in upgrading elastic search cluster.
  • shamail: Product Working Group wiki fully updated [1]
  • tristanC: 6 new TC members have been elected[2]
  • AJaegar: OpenStack API Quick Start converted to RST [3], and translated to German [4] and Japanese [5].
  • reed: section 2 and 3 of the OpenStack Shade tutorial merged. Now work on section [6].
  • sirushti: Heat just announced support for Python 3.4 [7].
  • AJaegar: All Documentation manuals have been updated with content for Liberty [8].

Upgrade to Gerrit 2.11

  • The OpenStack Infra team would like to upgrade from Gerrit 2.8 to 2.11.
  • Proposing to do the upgrade shortly after the Mitaka summit.
  • Motivation: Take advantage of some of the new REST API, ssh commands, and stream events features.
  • There is a big UI change in 2.11, in which 2.8 includes both the old and new style.
  • Preview 2.11 [9].
  • If you don’t like Gerrit 2.11, give Gertty [10] a try.

Service Catalog: The Next Generation (Cont.)

  • Continuing from last week summary…
  • Sean Dague realizes that while people want to go in much more radical directions here, we should be careful. This is not a blank slate, as there are enough users using it that we must do careful shifts that enable a new thing similar to the old thing.
    • Moving away from REST is too much, at least in the next 6 to 12 months.
    • Getting a service catalog over REST without auth, or tenant IDs gets us somewhere to figure out a DNS representation.

Establishing Release Liaisons for Mitaka

  • Doug Hellmann writes that the release management team relies on liaisons from each project to be available for coordination for work across all teams.
    • Responsibilities of release liaisons [11].
    • Signup [12].

Release Communication During Mitaka

  • Doug Hellmann begins one of many emails describing difference in the way we handle release management for the Mitaka cycle.
  • In the past, we’ve had communication issues where project team leads didn’t see or pay attention to release related announcements.
  • This email was sent to the list and individual project team leads, to improve the odds that all will see it.
  • “[release]” topic tag on the openstack-dev mailing list will be used.
    • All project team leads and release liaison should configuring their email client to ensure the messages are visible.

Requests + urllib3 + distro package (cont.)

  • Continuing discussions from last week…
  • Robert Collins comments a trivial workaround is to always use virtualenvs and not system-site-packages.
    • Has OpenStack infra team considered using system-site-packages?
      • Yes, but we take advantage of the python ecosystem uploading new releases to PyPI. We can then pretty instantly test compatibility of our software with new releases of dependencies.
  • A way forward is:
    • Get distros to fix their requests python dependencies
      • Ubuntu [13]
      • Fedora [14][15][16]
      • Fix existing known bugs in pip where such dependencies are violated by some operations.
    • Stop using vendorized version of requests and fork the project to use dependencies it should from the start.
    • Convince upstream to stop vendorizing urllib3.
    • Always use distro packages of requests, never from virtual environments.

Scheduler Proposal (cont.)

  • Continuing from last week’s summary…
  • Ed notes that Josh Harlow’s solution isn’t too different than the current design of hosts sending their state to the scheduler.
  • The reason for Cassandra proposal was to eliminate the duplication and have resources being scheduler and the scheduler itself all working with the same data.
    • This is the intent of the current design. The data can never be perfect, so work with what you have and hope the rest of the system deals with your mistakes and gracefully retry. (e.g. scheduled compute node no longer has resources to accommodate a request.)
    • To make this solution possible for downstream distributions and/or OpenStack users) you have to solve:
      • Cassandra developers upstream should start caring about OpenJDK.
      • Or Oracle should make its JVM free software.
    • Clint notes that Cassandra does not recommend OpenJDK [17].
      • Thomas adds:
        • Upstream does not test against OpenJDK.
        • They close bugs without fixing them when it only affects OpenJDK.
  • Thierry is generally negative about Java solutions as this being one of the reasons [18]. The free software JVM is not on par with the non-free JVM. We then indirectly force our users to use a non-free dependency. When the java solution is the only solution for a problem space, that might still be a good trade-off versus reinventing the wheel. However, for distributed locks and sharing state, there are some other good options out there.
    • Clint mentions that Zookeeper is different from Cassandra. He has had success with OpenJDK. It’s also available on Debian/Ubuntu making access for developers much easier.
