Orion Ubuntu Laptop Review: The Powerful MacBook Pro Alternative

Ubuntu

The choice of a new laptop for many consumers is still seen as the head-to-head comparison of Microsoft’s Windows 10 or Apple’s macOS. The third option of moving to a Linux-powered machine has always been a much trickier prospect. A dizzying range of Linux "flavors" coupled with the mysteries of hardware support stops many adept users from making the switch. What if you had an off-the-shelf approach to Linux hardware that just worked?

While the products that Ubuntu provides — such as Canonical Livepatch Service and Juju — are well-known in the cloud community, its corporate stance is not as recognized. It’s hoping to change that perception.

“Ubuntu is a very popular [operating system], and we are most dominant in public cloud,” explained Udi Nachmany, vice president of public cloud at Ubuntu.

QNAP Announces TS-453Bmini NAS That Supports Ubuntu Linux

Filed under
Linux
Ubuntu

NAS boxes have changed a lot over the years. From dumb storage, to multi-user storage, routing and network services, to web servers, to cloud servers, to full-blown media centers and PCs that can perform all of the above. QNAP is one of the leading NAS providers and it’s now releasing a new model with a lot of functionality.

The TS-453Bmini is a 64-bit quad-core 4-bay NAS built using an Intel J3455 Celeron processor, and is an update to the 2015 model, the TS-453mini (no B in the name). It’s a 10W TDP CPU that’s built on Apollo Lake, the successor to Braswell, and is the same generation chip as Kaby Lake (but for low power devices).

Core i7 6800K Linux CPU Scaling Benchmarks With Ubuntu 16.10

Filed under
Graphics/Benchmarks
Ubuntu

Earlier today I posted some Linux game CPU scaling benchmarks using a Core i7 6800K Broadwell-E For showing how current Linux games make use of (or not) multiple CPU cores, which originated from discussions by Linux gamers following the AMD Ryzen CPU launch with how many cores are really needed. While going through the process of running those Linux game CPU scaling benchmarks, I also ran some other workloads for those curious.

For those wondering how other Linux CPU-focused workloads are scaling across multiple CPU cores with recent versions of the Linux kernel and distributions, such as Ubuntu 16.10 with Linux 4.8, you may find these additional data-sets interesting. Some of the used tests are also in common with this weekend's AMD Ryzen CPU Core Scaling Performance article.

Security Leftovers

  • Security updates for Monday
  • Recursive DNS Server Fingerprint Problem

    Our goal is to identify hijacked resolvers by analyzing their fingerprints, in order to increase safety of Internet users. To do that, we utilize data collected via RIPE Atlas (atlas.ripe.net).

  • Online developer tutorials are spreading XSS and SQL injection flaws

    The researchers, from across three universities in Germany and Trend Micro, checked the PHP code bases of more than 64,000 projects on Github and uncovered more than 100 vulnerabilities that they believe might have been introduced as a result of developers picking up the code that they used from online tutorials.

  • BrickerBot, the permanent denial-of-service botnet, is back with a vengeance

    BrickerBot, the botnet that permanently incapacitates poorly secured Internet of Things devices before they can be conscripted into Internet-crippling denial-of-service armies, is back with a new squadron of foot soldiers armed with a meaner arsenal of weapons.

  • Webroot antivirus goes bananas, starts trashing Windows system files
    Webroot's security tools went berserk today, mislabeling key Microsoft Windows system files as malicious and temporarily removing them – knackering PCs in the process. Not only were people's individual copies of the antivirus suite going haywire, but also business editions and installations run by managed service providers (MSPs), meaning companies and organizations relying on the software were hit by the cockup. Between 1200 and 1500 MST (1800 and 2100 UTC) today, Webroot's gear labeled Windows operating system data as W32.Trojan.Gen – generic-Trojan-infected files, in other words – and moved them into quarantine, rendering affected computers unstable. Files digitally signed by Microsoft were whisked away – but, luckily, not all of them, leaving enough of the OS behind to reboot and restore the quarantined resources.
  • How The Update Framework Improves Security of Software Updates
    Updating software is one of the most important ways to keep users and organizations secure. But how can software be updated securely? That's the challenge that The Update Framework (TUF) aims to solve. Justin Cappos, assistant professor at New York University, detailed how TUF works and what's coming to further improve the secure updating approach in a session at last week's DockerCon 17 conference in Austin, Texas. Simply using HTTPS and Transport Layer Security (TLS) to secure a download isn't enough as there have been many publicly reported instances of software repositories that have been tampered with, Cappos said.
  • Security Updates for Ubuntu Phone to End in June
    Security updates for Ubuntu phone and tablet will end this June, Canonical has confirmed. Current OTA updates are currently limited to critical fixes and security updates — a decision we were first to tell you back in January. But after June 2017 Canonical “will no longer deliver any further updates”.
  • Canonical to stop supporting Ubuntu Phone in June
    Canonical had already announced development of its Ubuntu Phone software was ending. Now we know when the final nail goes in the coffin: June.
  • Malware Hunts And Kills Poorly Secured Internet Of Things Devices Before They Can Be Integrated Into Botnets
    Researchers say they've discovered a new wave of malware with one purpose: to disable poorly secured routers and internet of things devices before they can be compromised and integrated into botnets. We've often noted how internet-of-broken-things devices ("smart" doorbells, fridges, video cameras, etc.) have such flimsy security that they're often hacked and integrated into botnets in just a matter of seconds after being connected to the internet. These devices are then quickly integrated into botnets that have been responsible for some of the worst DDoS attacks we've ever seen (including last October's attack on DYN).

GNOME/GTK News

  • The Way GNOME Handles Wallpapers Really Annoys Me
    I love GNOME Shell — and no, not just because I’ve little choice now that is Ubuntu’s default desktop! But the more I use GNOME the more I learn that the desktop environment, like every other, has its own share of quirks, bugs and inconsistencies. Like the following appreciably niche niggle in the the way GNOME handles desktop wallpapers.
  • Drag-and-drop in lists
    I’ve recently had an occasion to implement reordering of a GtkListBox via drag-and-drop (DND). It was not that complicated. Since I haven’t seen drag-and-drop used much with list boxes, here is a quick summary of what is needed to get the basics working.

  • How Kubernetes is making contributing easy
    As the program manager of the Kubernetes community at Google, Sarah Novotny has years of experience in open source communities including MySQL and NGINX. Sarah sat down with me at CloudNativeCon in Berlin at the end of March to discuss both the Kubernetes community and open source communities more broadly. Among the topics we covered in the podcast were the challenges inherent in shifting from a company-led project to a community-led one, principles that can lead to more successful communities, and how to structure decision-making.

    Today, supporting Linux is as critical to Microsoft as it is to Red Hat and SUSE.
  • How to make branding decisions in an open community
    On April 18, Docker founder Solomon Hykes made a big announcement via a pull request in the main Docker repo: "Docker is transitioning all of its open source collaborations to the Moby project going forward." The docker/docker repo now redirects to moby/moby, and Solomon's pull request updates the README and logo for the project to match. Reaction from the Docker community has been overwhelmingly negative. As of this writing, the Moby pull request has garnered 7 upvotes and 110 downvotes on GitHub. The Docker community is understandably frustrated by this opaque announcement of a fait accompli, an important decision that a hidden inner circle made behind closed doors. It's a textbook case of "Why wasn't I consulted?"

Ubuntu 17.04: Unity's swan song?

For the most part, not much has changed on Ubuntu's Desktop edition in the past year. Unity 7 has more or less remained the same while work was progressing on the next version of the desktop, Unity 8. However, now that both desktops are being retired in favour of the GNOME desktop, running Ubuntu 17.04 feels a bit strange. This week I was running software that has probably reached the end of its life and this version of Ubuntu will only be supported for nine months. I could probably get the same desktop experience and most of the same hardware support running Ubuntu 16.04 and get security updates through to 2021 in the bargain. In short, I don't think Ubuntu 17.04 offers users anything significant over last year's 16.04 LTS release and it will be retired sooner. That being said, I could not help but be a little wistful about using Unity 7 again. Even though it has been about a year since I last used Unity, I quickly fell back into the routine and I was once more reminded how pleasant it can be to use Unity. The desktop is geared almost perfectly to my workflow and the controls are set up in a way that reduces my mouse usage to almost nothing. I find Unity a very comfortable desktop to use, especially when application menus have been moved from the top panel to inside their own windows. While there are some projects trying to carry on development of Unity, this release of Ubuntu feels like Unity's swan song and I have greatly enjoyed using the desktop this week. While there is not much new in Ubuntu 17.04, the release is pretty solid. Apart from the confusion that may arise from having three different package managers, I found Ubuntu to be capable, fairly newcomer friendly and stable. Everything worked well for me, at least on physical hardware. Unity is a bit slow to use in a virtual machine, but the distribution worked smoothly on my desktop computer. Read more
