How IBM’s LinuxONE Has Evolved For the New Open Source Cloud

Filed under
Interviews
OSS

LinuxONE is IBM’s Linux Server. The LinuxONE server runs the major distributions of Linux; SUSE, Red Hat and Canonical’s Ubuntu. The server also runs open source databases like Mongo DB , PostgreSQL and MariaDB allowing for both horizontal growth and vertical scale, as demonstrated by running a 2TB Mongo database without sharding. Several of the features built into this system support the constant innovation inherent in the open source movement while maintaining the performance and reliability required by Enterprise clients; for example, Logical Partitions (LPARs) allow clients to host a development environment on the same system as production with zero risk.

The Big Android Dev Interview: Maarten Edgar

Filed under
Android
Interviews

Good question! Well, I like [that] it's open source, I like that [in mobile development in particular] you make something and it's "one there." Specifically or Android, I like that it runs on a lot of different things. I've done some commercial Google Glass development — and, you know, it has a skin, but it is Android.

I like that you can do really useful stuff [with Android], it keeps on evolving and getting more interesting, so I like that.

What I don't like is... implementations of Android that are not truly Android — Samsung had this problem where, for example, you'd ask something in the system, you'd do a system call [asking] what kind of resolution it was and it would lie to you! It would say "oh no, I'm HDPI" when really it was an MDPI thing. And that just pisses me off. Incorrect documentation. And what's difficult is all the different device sizes. That is a challenge. Not necessarily something that I hate but it is challenging.

Android
Interviews

My name is Jolanda Verhoef and I've been developing for Android for six years, focusing mainly on architecture. [At the Big Android BBQ] I gave a talk on architecture together with RxJava. So, how can RxJava help you create a nice clean architecture. I work at a company called Blendle, which is a startup in the Netherlands, and before that I worked at companies like Philips, Dutch railway stations, Enexis, stuff like that. And I built my own app for geocaching as well.

2016 LiFT Scholarship Winner Ahmed Alkabary: A Recent Graduate and Aspiring SysAdmin

Filed under
Interviews

For me, I don’t just appreciate the Linux operating system but I also feel like it has become my life. Whenever I’m on a Linux based computer I feel like I’m at home. You can say it is a passion that has taken many years of cultivating to become integrated in my life the way it is today.

In 2011 I was eager to purchase a brand new computer, but to my dismay the shop had only one computer that met my requirements. Although unbeknownst to me the computer had a specific operating system that I was unfamiliar with. The operating system was pre-installed with Linux, specifically openSuse. I was so hesitant to purchase the computer but proceeded anyway. I hoped to change the operating system once I got home, but I was unsure of what came over me to keep Linux. But to this day I feel I have yet to make a decision that would have a greater impact on my life then the day I decided to keep Linux.

Be Cautious With Containers Says FutureAdvisor’s DevOps Director

Filed under
Interviews

Docker is a fantastic technology, but it’s not one that’s well understood. If we take a look at the lessons of the past, there was more hype than understanding around cloud as well — and before that, around virtualization. I’m seeing the same patterns repeat themselves here, and in some circles this is a far from popular viewpoint.

Linux Foundation Certified Engineer: Ronni Jensen

Linux
Interviews

I've actually been distro-hopping for a long time, going back and forth between various Debian-derivatives, but the last couple of years I've been a fan of openSUSE. I like openSUSE's way of doing things and that I have a choice between rock-solid (Leap) and bleeding edge (Tumbleweed). Right now, though, my computers are running a mix of openSUSE Leap, CentOS 7, and RHEL 7.

I’d love to show that Red Hat folks outside of the Fedora project are
committed to the greater community. I’d also love to get folks up to
speed on container security (the topic of my presentation).

Interviews

Luis Motta was born in 1963 on the same day as Mick Jagger, which may explain why he has been a rock and roll guitar player since 1982. Motta plays in three different bands. He and his friends play gigs at local bars with a preference for heavy rock. Motta says, “Louder is better!” His favorite music groups are Rush, System of a Down, and Red Fang. As a guitarist, he likes Alex Lifeson. “Today, me and a friend, Jesiel Rocha, give lectures on the use of free software for music recording,” said Luis.

ura and the Challenges of Open Source Design

Filed under
Interviews
OSS

Elio Qoshi is the person behind ura, a fascinating design studio dedicated to improving design in free and open source projects. As part of that mission, ura works with projects of all budgets. When we talk about open source, we’re usually talking code first and then—maybe—documentation second. Design is often an after-thought. But as designers like Elio get involved in open source culture, that order could eventually change.

  • [LabPlot] Improved data fitting in 2.5
    Until now, the fit parameters could in principle take any values allowed by the fit model, which would lead to a reasonable description of the data. However, sometimes the realistic regions for the parameters are known in advance and it is desirable to set some mathematical constrains on them. LabPlot provides now the possibility to define lower and/or upper bounds for the fit parameters and to limit the internal fit algorithm to these regions only.
  • [GNOME] Maps Towards 3.28
    Some work has been done since the release of 3.26 in September. On the visual side we have adapted the routing sidebar to use a similar styling as is used in Files (Nautilus) and the GTK+ filechooser.
  • MX 17 Beta 2
  • MiniDebconf in Toulouse
    I attended the MiniDebconf in Toulouse, which was hosted in the larger Capitole du Libre, a free software event with talks, presentation of associations, and a keysigning party. I didn't expect the event to be that big, and I was very impressed by its organization. Cheers to all the volunteers, it has been an amazing week-end!
  • DebConf Videoteam sprint report - day 0
    First day of the videoteam autumn sprint! Well, I say first day, but in reality it's more day 0. Even though most of us have arrived in Cambridge already, we are still missing a few people. Last year we decided to sprint in Paris because most of our video gear is stocked there. This year, we instead chose to sprint a few days before the Cambridge Mini-Debconf to help record the conference afterwards.
  • Libre Computer Board Launches Another Allwinner/Mali ARM SBC
    The Tritium is a new ARM single board computer from the Libre Computer Board project. Earlier this year the first Libre Computer Board launched as the Le Potato for trying to be a libre and free software minded ARM SBC. That board offered better specs than the Raspberry Pi 3 and aimed to be "open" though not fully due to the ARM Mali graphics not being open.
  • FOSDEM 2018 Will Be Hosting A Wayland / Mesa / Mir / X.Org Developer Room
    This year at the FOSDEM open-source/Linux event in Brussels there wasn't the usual "X.Org dev room" as it's long been referred to, but for 2018, Luc Verhaegen is stepping back up to the plate and organizing this mini graphics/X.Org developer event within FOSDEM.
  • The Social Network™ releases its data networking code
    Facebook has sent another shiver running up Cisco's spine, by releasing the code it uses for packet routing. Open/R, its now-open source routing platform, runs Facebook's backbone and data centre networks. The Social Network™ first promised to release the platform in May 2017. In the post that announced the release, Facebook said it began developing Open/R for its Terragraph wireless system, but since applied it to its global fibre network, adding: “we are even starting to roll it out into our data center fabrics, running inside FBOSS and on our Open Compute Project networking hardware like Wedge 100.”
  • Intel Icelake Support Added To LLVM Clang
    Initial support for Intel's Icelake microarchitecture that's a follow-on to Cannonlake has been added to the LLVM/Clang compiler stack. Last week came the Icelake patch to GCC and now Clang has landed its initial Icelake enablement too.
  • Microsoft's Surface Book 2 has a power problem
     

    Microsoft’s Surface Book 2 has a power problem. When operating at peak performance, it may draw more power than its stock charger or Surface Dock can handle. What we’ve discovered after talking to Microsoft is that it’s not a bug—it’s a feature.

  • The Big Changes So Far For The Linux 4.15 Kernel - Half Million New Lines Of Code So Far
    We are now through week one of two for the merge window of the Linux 4.15 kernel. If you are behind on your Phoronix reading with the many feature recaps provided this week of the different pull requests, here's a quick recap of the changes so far to be found with Linux 4.15:
  • Intel 2017Q3 Graphics Stack Recipe Released
    Intel's Open-Source Technology Center has put out their quarterly Linux graphics driver stack upgrade in what they are calling the latest recipe. As is the case with the open-source graphics drivers just being one centralized, universal component to be easily installed everywhere, their graphics stack recipe is just the picked versions of all the source components making up their driver.
  • Intel Ironlake Receives Patches For RC6 Power Savings
    Intel Ironlake "Gen 5" graphics have been around for seven years now since being found in Clarkdale and Arrandale processors while finally now the patches are all worked out for enabling RC6 power-savings support under Linux.

Security: Google and Morgan Marquis-Boire

  • Google: 25 per cent of black market passwords can access accounts

    The researchers used Google's proprietary data to see whether or not stolen passwords could be used to gain access to user accounts, and found that an estimated 25 per cent of the stolen credentials can successfully be used by cyber crooks to gain access to functioning Google accounts.

  • Data breaches, phishing, or malware? Understanding the risks of stolen credentials

    Drawing upon Google as a case study, we find 7--25\% of exposed passwords match a victim's Google account.

  • Infosec star accused of sexual assault booted from professional affiliations
    A well-known computer security researcher, Morgan Marquis-Boire, has been publicly accused of sexual assault. On Sunday, The Verge published a report saying that it had spoken with 10 women across North America and Marquis-Boire's home country of New Zealand who say that they were assaulted by him in episodes going back years. A woman that The Verge gave the pseudonym "Lila," provided The Verge with "both a chat log and a PGP signed and encrypted e-mail from Morgan Marquis-Boire. In the e-mail, he apologizes at great length for a terrible but unspecified wrong. And in the chat log, he explicitly confesses to raping and beating her in the hotel room in Toronto, and also confesses to raping multiple women in New Zealand and Australia."
