Canonical on So-called 'Private Cloud'

Ubuntu
  • 451 Research benchmarks public and private infrastructure cost

    451 Research’s latest report, ‘Busting the myth of private cloud economics ’, found that Canonical’s managed private OpenStack offering, BootStack, delivers private cloud with a TCO that matches public clouds. For multi-cloud operations, enterprise can benefit from a cost effective infrastructure by combining competitive public cloud services with Canonical’s managed private OpenStack cloud on-premise.

  • Private Cloud May Be the Best Bet: Report

    News flash: Private cloud economics can offer more cost efficiency than public cloud pricing structures.

    Private (or on-premises) cloud solutions can be more cost-effective than public cloud options, according to "Busting the Myths of Private Cloud Economics," a report 451 Research and Canonical released Wednesday. That conclusion counters the notion that public cloud platforms traditionally are more cost-efficient than private infrastructures.

    Half of the enterprise IT decision-makers who participated in the study identified cost as the No. 1 pain point associated with the public cloud. Forty percent mentioned cost-savings as a key driver of cloud migration.

    "We understand that people are looking for more cost-effective infrastructure. This was not necessarily news to us," said Mark Baker, program director at Canonical.

How Red Hat Linux is helping reclaim the fastest supercomputer title for the US

Red Hat

All the world's fastest supercomputers now run Linux, so it's no surprise that the US Department of Energy's Summit supercomputer at Oak Ridge National Laboratories runs Linux. Specifically, it runs Red Hat Enterprise Linux (RHEL).

Of course, Summit's 200-petaflop speed -- that's 200 quadrillion (peta-) floating point operations per second (flops) -- comes largely from its hardware. How fast is that? By comparison, China's Sunway TaihuLight, the official fastest supercomputer in the world, according to November 2017's Top 500 list, has a speed of 93.01 petaflops.

Top 5 games you can play on your favorite Linux desktop

Filed under
Linux
Gaming

I’ve never really been into gaming, that is, the shoot-em-up type of gaming, but in the early days of Linux, even just a few years ago, most default installations of desktop Linux came with a bunch of games installed. They were mostly card games and some simple strategy games, but they were enough to satisfy the casual gamer. Not sure why, but that practice seems to have gone the way of the dodo.

So if you want to play those same games that used to come preinstalled on practically every desktop Linux distribution just a few years back, you’ll need to install them yourself. That’s not such a big problem since they’re still available in the default repositories. What if you want more than just simple card and strategy games? No problem there too, because there are some very advanced strategy and first-person shooter games that you can install and play on Linux.

Winepak and Game on GNU/Linux Using Wine

Filed under
Gaming
  • winepak, a project to get Windows games packaged with Wine & Flatpak for an easy Linux installation

    winepak [Official Site] is another interesting Wine-related project. One that aims to package up an assortment of Windows-only games that work in Wine using the power of Flatpak packages.

    I'm not going to get into the politics of Snap vs Flatpak, mostly because I don't care for the arguments surrounding it and end-users shouldn't care as long as they work and work well.

    Much like today's previous post about Track Mania Nations Forever having an easy to use Snap package, winepak seems to aim a bit higher and offer a repository of games. The advantage of using such packages (Snaps or Flatpaks), is that it should come with everything you need to get the Windows game running on Linux, without having to mess around with configurations. It's a new project though, so there's likely a fair amount of kinks to work out.

  • Want to play Track Mania Nations Forever on Linux using Wine? There's a snap for that

    I actually played one of the Track Mania games years ago before being a Linux user and I had a serious amount of fun with it, so things brings back some good memories.

    I'm not often one to advocate the use of Wine, but taking into account that it's free, old and likely never to be ported to Linux, making use of Wine for a game that works so well seems like a perfect fit. Having it all configured for you with a single package like this, certainly makes it a lot easier too.

ICNexus’ “SBC3100” SBC runs Ubuntu or Android on a Rockchip RK3399 with up to 4GB RAM and 16GB flash plus HDMI 2.0, DP, eDP, MIPI-DSI and -CSI, 9-36V power, optional WiFi/BT, and a mini-PCIe slot with optional 3G or 4G.

Taiwan-based ICNexus’ SBC3100 joins a growing list of SBCs that feature, the hhigh-end Rockchip RK3399 SoC, and like most, it taps the high-end SoC to provide an extensive feature list. Unlike most we’ve seen, however, it is not publicly priced and appears to be a proprietary product, such as Aaeon’s Pico-ITX based RICO-3399.

  • Intelligence agency National Cyber Security Centre is working with Dixons Carphone on huge data breach

    The National Cyber Security Centre (NCSC), part of GCHQ, said today it is working with Dixons Carphone on mitigation measures, after the retailer said it was investigating a data breach involving 5.9m payment cards and 1.2m personal data records.

    The company announced earlier on that there was an attempt to compromise 5.9m cards in one of the processing systems of Currys PC World and Dixons Travel stores.

    Security researchers have found a critical flaw in Windows 10 where Cortana can be manipulated into executing Powershell commands on locked devices.

    Attackers can misuse this vulnerability to retrieve confidential data, reset the password, log into a device, and even execute codes from above the lock screen. The only sense of satisfaction is that it requires physical access to the device.

  • Windows 10 Cumulative Update KB4284835 Might Be Failing to Install as Well

    Windows 10 April 2018 Update has received a new cumulative update as part of this month’s Patch Tuesday cycle, and although it seemed to install correctly at first, it looks like some users are now hitting issues with this new release.
    Windows 10 cumulative update KB4284835 brings several important fixes and it resolves a bug causing the April 2018 Update to fail with a black screen on a number of systems.

    Microsoft says it’s aware of just one known issue in this cumulative update, but as it turns out, KB4284835 fails to install in some cases, eventually causing an infinite loop where the update is listed as successfully installed, only to be re-offered again after every boot.

    There are several posts on reddit pointing to such an issue, and for the time being, no workaround appears to be available. Manually installing the update does not correct this behavior.

Linux Gets Loud

Filed under
Linux

Linux is ready for prime time when it comes to music production. New offerings from Linux audio developers are pushing creative and technical boundaries. And, with the maturity of the Linux desktop and growth of standards-based hardware setups, making music with Linux has never been easier.

Linux always has had a place for musicians looking for inexpensive rigs to record and create music, but historically, it's been a pain to maintain. Digging through arcane documentation and deciphering man pages is not something that interests many musicians.

Loading up Linux is not as intimidating as it once was, and a helpful community is going strong. Beyond tinkering types looking for cheap beats, users range in experience and skill. Linux is still the underdog when it comes to its reputation for thin creative applications though.

  • Android Devices With Misconfigured ADB, a Ripe Target for Cryptojacking Malware

    Poorly configured Android devices, where the Android Debug Bridge is left enabled, have become an attractive target for hackers. According to researchers, adversaries are using the common misconfiguration to install cryptojacking malware on a wide selection of Android-based IoT devices ranging from maritime computer systems, TVs, DVRs and some mobile phone models.

    Android Debug Bridge (ADB) is an Android OS developer function that, when enabled, allows remote users to access a Unix shell to conduct command line device maintenance. According to researcher Kevin Beaumont, thousands of Android type devices ship with ADB enabled, allowing hackers to remotely access them.

CPTPP jeopardises the future of open source software: OSIA

Filed under
OSS

Open Source Industry Australia (OSIA) is calling upon the federal government to scrap the CPTPP (Comprehensive & Progressive agreement for Trans Pacific Partnership) over provisions that could decimate the Australian open source community.

As the Senate Standing Committee on Foreign Affairs, Defence & Trade conducts its inquiry into the revised international trade agreement that incorporates most of the original TPP’s provisions, OSIA has called for Australia to withdraw from the deal before it is ratified.

The open source software peak body has identified loosely worded clauses within the chapter on electronic commerce that could have major impacts on creators and users of open source software.

The offending section is Article 14.17 of the CPTPP, which prohibits requirements for transfer or access to the source code of computer software. OSIA argues that the exceptions within this article are far too narrow and ‘carelessly worded’, leaving them entirely susceptible to interpretation.

Canonical/Ubuntu Watching You

  • Two-thirds of Ubuntu users are happy to give up data on their PC
    As announced back at the start of the year, Canonical made the decision that Ubuntu would collect data on its user base – and now the initial results of those statistics have been published by the firm, including the headline fact that 67% of users were happy to provide details of their PC (and other bits and pieces). So, this scheme that has been unfavorably compared to Microsoft’s collection of telemetry data in Windows 10, which has long been a point of controversy. However, it appears that the majority of folks are happy to give up their data to the company providing their Linux distribution, and don’t seem perturbed by this prospect.
  • Ubuntu reports 67% of users opt in to on-by-default PC specs slurp [Ed: 33% of Ubuntu users say to Canonical "don't spy on me" and Canonical then counts them, which means that Canonical collects data on them, too]
    However just 33 per cent of the undisclosed number of users Canonical’s analysed didn’t opt in to the slurpage. Which is where things get a little bit weird, because Canonical’s post reports an “Opt In rate”. Yet the data slurpage is selected by default: there’s an active opt out but a passive opt in.
  • The Average Ubuntu Install Takes 18 Minutes (And Other Stats)
    Did you know that the average Ubuntu install takes just 18 minutes? That’s one of several nuggets of information Canonical has collected (and now revealed) thanks to the new “Ubuntu Report” tool included in Ubuntu 18.04 LTS. This tool, when given permission to, collects non-identifiable system data about new Ubuntu installs and upgrades and ferries it back to Canonical for analysis.
