New Open Source Effort Provides Free Cloud Orchestration as a Service

Filed under
Server
OSS

Specifically, GoGrid-sponsored OpenOrchestration.org hopes to advance the open data services ecosystem with a free orchestration service, software library and community. Essentially, the effort aims to do for entire clouds what virtualization did for servers by delivering a range of complex, “full-stack” solutions. Users, in turn, can then easily deploy complex applications in a single cloud, across multiple clouds, on-premises or any combination in between.

Who's using Docker?

Filed under
GNU
Linux
Server

I've spent the last couple of months working an internship for The Linux Foundation, doing research on new developments and adoption trends in the open source industry. If you have spent any amount of time reading about open source over the last year, you have probably heard about Docker; a lot of people are talking about it these days and the impact it's going to have on virtualization and DevOps.

With new technologies like this, it can often be challenging to filter out the hype and understand the practical implications. Additionally, complex jargon often makes subjects like Linux containers confusing to the layman and limits discussion to those who are deeply knowledgeable on the subject. With this article, I will step back for a moment from the discussion of what Docker can do to focus on how it is changing the Linux landscape.

The Linux Supercomputers We Secretly Fear Will Become Sentient

Filed under
Server

Every year, the Top 500 list of the world's fastest supercomputers is released. A list filled with machines containing tens of thousands of nodes and capable of cranking out enough petaflops per second to make your head spin.

And, of course, this list is absolutely dominated by machines powered by Linux.

This is awesome. But, really, we all know this. Let's dig a little deeper into these Goliath computers that will, someday, become sentient and rise up against their human creators.

DESKTOP CONTAINERS – THE WAY FORWARD

Filed under
Red Hat
Server

One feature we are spending quite a bit of effort in around the Workstation is container technologies for the desktop. This has been on the wishlist for quite some time and luckily the pieces for it are now coming together. Thanks to strong collaboration between Red Hat and Docker we have a great baseline to start from. One of the core members of the desktop engineering team, Alex Larsson, has been leading the Docker integration effort inside Red Hat and we are now preparing to build onwards on that work, using the desktop container roadmap created by Lennary Poettering.

X.Org Server 1.16 Delayed To Let In Non-PCI Graphics Support

Filed under
Graphics/Benchmarks
Server

X.Org Server 1.16 has been delayed. However, it's not been delayed like in some of the more notorious past releases due to outstanding bugs, etc, but over letting in a late feature to this latest revision of the X11 server.

There was a lot of developer interest and pressure to let non-PCI device support get merged for the 1.16 stable release. This non-PCI support is needed for allowing the NVIDIA Tegra (open-source) graphics driver to work properly in an easy manner since it's not exposed as a PCI VGA device. Thierry Reding at NVIDIA along with support from other developers worked out adding this non-PCI graphics support on the X.Org Server side.

Firms that use Linux-based cloud servers are overspending on their cloud capacity by more than £1 billion annually for Infrastructure-as-a-Service (Iaas).

According to cloud provider ElasticHosts, the dominant payment model for IaaS is highly inefficient, and even at its best, companies are overpaying by as much as 50 per cent.

  • MariaDB X4 brings smart transactions to open source database

    MariaDB has come a long way from its MySQL database roots. The open source database vendor released its new MariaDB X4 platform, providing users with "smart transactions" technology to enable both analytical and transactional databases. MariaDB, based in Redwood City, Calif., was founded in 2009 by the original creator of MySQL, Monty Widenius, as a drop-in replacement for MySQL, after Widenius grew disillusioned with the direction that Oracle was taking the open source database. Oracle acquired MySQL via its acquisition of Sun Microsystems in 2008. Now, in 2020, MariaDB still uses the core MySQL database protocol, but the MariaDB database has diverged significantly in other ways that are manifest in the X4 platform update. The MariaDB X4 release, unveiled Jan. 14, puts the technology squarely in the cloud-native discussion, notably because MariaDB is allowing for specific workloads to be paired with specific storage types at the cloud level, said James Curtis, senior analyst of data, AI and analytics at 451 Research.

  • Copy-left behind: Permissive MIT, Apache open-source licenses on the up as developers snub GNU's GPL

    Permissive open-source software licenses continue to gain popularity at the expense of copyleft licenses, according to a forthcoming report from WhiteSource, a biz that makes software licensing management tools. Permissive licenses include the MIT and Apache 2.0 licenses and are known as such because the permit licensors to do more or less what they want with the covered software, with minimal caveats, and without imposing obligations like sharing code revisions. Copyleft licenses like GPLv2, GPLv3, and LGPLv2.1 convey similar freedom, while, to put it simply, requiring that licensors not release versions or derivatives of the licensed code that restrict said freedom.

Programming: Rust, C and Python

  • Announcing Better Support for Fuzzing with Structured Inputs in Rust

    Today, on behalf of the Rust Fuzzing Authority, I’d like to announce new releases of the arbitrary, libfuzzer-sys, and cargo fuzz crates. Collectively, these releases better support writing fuzz targets that take well-formed instances of custom input types. This enables us to combine powerful, coverage-guided fuzzers with smart test case generation. Install or upgrade cargo fuzz with: cargo install --force cargo-fuzz To upgrade your fuzz targets, bump your libfuzzer-sys dependency to 0.2.0 on crates.io. That should be all that’s needed for most cases. However, if you were already using Arbitrary inputs for your fuzz target, some changes will be required. See the upgrading fuzz targets section below for more details.

  • Use this Python script to find bugs in your Overcloud

    OpenStack stores and manages a bunch of log files on its Overcloud nodes and Undercloud host. Therefore, it's not easy to use OSP log files to investigate a problem you're having, especially when you don't even know what could have caused the problem. If that's your situation, LogTool makes your life much easier! It saves you the time and work it would otherwise take to investigate the root cause manually. Based on a fuzzy string matching algorithm, LogTool provides all the unique error and warning messages that have occurred in the past. You can export these messages for a particular time period, such as 10 minutes ago, an hour ago, a day ago, and so on, based on timestamp in the log.

  • Confidential computing promises secure cloud apps

    Enterprises, governments and other organizations all sit on vast troves of data that cannot be processed due to security and privacy concerns. To address this limitation, researchers and vendors have developed various confidential computing techniques to safely process sensitive data. Confidential computing is particularly important for organizations in heavily regulated industries or sectors where opportunities for running workloads on the public cloud are severely limited, such as government, telecommunications, healthcare and banking. Confidential computing protects data at rest, which enables organizations to deploy sensitive workloads off premises and provides further protection to sensitive workloads on premises. [..]. "If projects and products can show regulators and legislators that the levels of security are sufficient to meet their requirements, then deployment to public clouds becomes plausible for a great many more applications and use cases," said Mike Bursell, chief security architect at Red Hat.

  • Akraino Edge Stack Enables Connected Car, AR/VR, AI Edge, and Telco Access Edge Application Use Cases

    LF Edge, an umbrella organization within the Linux Foundation that aims to establish an open, interoperable framework for edge computing independent of hardware, silicon, cloud, or operating system, today announced the availability of Akraino Edge Stack Release 2 (“Akraino R2”). Akraino’s second release furthers the power of intelligent edge with new and enhanced deployable, self-certified blueprints for a diverse set of edge use cases. Launched in 2018, and now a Stage 3 (or “Impact” stage) project under the LF Edge umbrella, Akraino Edge Stack is creating an open source software stack that supports a high-availability cloud stack optimized for edge computing systems and applications. Designed to improve the state of edge cloud infrastructure for enterprise edge, over-the-top (OTT) edge, and carrier edge networks, it offers users new levels of flexibility to scale edge cloud services quickly, to maximize the applications and functions supported at the edge, and to help ensure the reliability of systems that must be up at all times. “The Akraino community has grown rapidly in the past year, and now includes contributions from 70 percent of LF Edge Premium member companies and countless other ecosystem partners beginning to deploy the blueprints across the globe,” said Arpit Joshipura, general manager, Networking, Automation, Edge and IoT, the Linux Foundation. “With R2, strong community collaboration brings even more blueprints to the ecosystem that support current and future technology at the open source edge.”

  • Study Shows The Internet Is Hugely Vulnerable To SIM Hijacking Attacks

    U.S. Wireless carriers are coming under heavy fire for failing to protect their users from the practice of SIM hijacking. The practice usually involves conning or bribing a wireless employee to port a victim's cell phone number right out from underneath them, letting the attacker then pose as the customer to potentially devastating effect. Carriers are facing numerous lawsuits from victims who say attackers used the trick to first steal their identity, then millions in cryptocurrency, or even popular social media accounts.

  • Restoring DNS Privacy

    Stefan and I have been taking last week to add DNS over TLS into IPFire - another step to make DNS more private. Here is what we have done. Cleaning up some mess IPFire has multiple places where DNS servers could be configured. If you were using PPP for your Internet connection, you would have set this up with your dialup settings. If you were using a static IP address, then you would have set up the DNS servers with it in the setup. If you were using DHCP, you had a page on the web user interface to go to. This is not only confusing for the user, but also there were the places in the code where those settings were applied. Now, we have created an entire new page which combines all of it together! You will have a list where you can set all DNS servers and set new settings. [...] This will be release with Core Update 140. Amongst the many new features, we have removed a lot of code that has caused us a lot of trouble in the past and rewritten many things entirely from scratch.
