6 RFCs for understanding how the internet works

Friday 6th of July 2018 04:31:37 PM
Reading the source is an important part of open source software. It means users have the ability to look at the code and see what it does. But "read the source" doesn[he]#039[/he]t apply only to code. Understanding the standards the code implements can be just as important. These standards are codified in documents called "Requests for Comments" (RFCs) published by the Internet Engineering Task Force (IETF). Thousands of RFCs have been published over the years, so we collected a few that our contributors consider must-reads.

OSS: Apache Cassandra, Jib,WSO2 and More

  • Apache Cassandra at 10: Making a community believe in NoSQL
    Ten years ago this month, when Lehman Brothers was still just about in business and the term NoSQL wasn't even widely known, let alone an irritant, Facebook engineers open-sourced a distributed database system named Cassandra. Back then, the idea that huge numbers of companies would need a scalable database was almost laughable – and that grip of traditional relational database systems is reflected in the mythical moniker given to what would become one of the first of many databases designed to run on a cluster of machines. Named after the Greek figure who was cursed to utter the truth but was never believed, Cassandra might seem an odd choice for a system whose raison d'être is believability – but it delivered a nice dig at the stalwarts of the RDBMS world… and their trust in a false Oracle.
  • Google Launches Jib, Automated Container Packaging for Java Apps
    Google has released software that could automate the packaging of a Java program so that it can be run in the cloud-native environment. Jib is an open-source Java “containerizer,” one that handles all the steps of packaging your application into a container image, according to Appu Goundan and Qingyang Chen, two Google engineers who co-wrote a blog post announcing the new technology. Created over two decades ago at Sun Microsystems, Java was introduced as a “write once, run anywhere” programming language, where all the code would be packaged in a JAR file, and run by a Java Virtual Machine on any platform. The requirements for running code anywhere have expanded with the introduction of containerization, however. Few shops are Java-only these days, and many are turning to containerization for true application portability,

There are still some minor quirks, but Florian recommended to focus on the big picture instead of spending too much time on small details and edge cases. I also have to release pgpainless to maven central and establish some kind of release cycle. It will be a future challenge for me personally to synchronize the releases of smack-openpgp and pgpainless.
  • Collaborative World Shaping: Why Open-Source Tech Matters in a For-Impact Future
    How many lives could be saved if there was a way to vastly cut down inefficiency and through bureaucracy, by problem solving at a global scale? Could technology help us reach more individuals in need more meaningfully, substantially helping people affected by disasters – in less time? The technology is already out there – but not enough people know about it. In 2017, Hurricane Irma—the strongest hurricane ever recorded in the Atlantic Ocean—made landfall; with widespread, “catastrophic” damage, disaster relief organizations were overwhelmed. “A lot of traditional means of crisis response are very top down, and they didn’t really kick in — we saw headlines about how the Red Cross didn’t show up to shelters,” said Greg Bloom, a community organizer and civic hacker who knew he had to step in to assist.
  • The First Open-Source Smart Contract Platform to be Started by Rootstock
    RSK Labs, formerly known as Rootstock, an Argentinian startup building the first open-source smart contract platform with a 2-way peg to Bitcoin.RSK Labs CEO Diego Gutiérrez Zaldívar on Bitcoin Smart Contracts Sidechain and Crypto Industry Challenges. Even though at this point of time the 2-way peg security of the RSK blockchain is still relying on a group of third parties called ‘Federation’, in the future the developers promise to bring a “trustless” automatic peg. How fast this happens to some degree depends on the overall miners support. The company says its goal is to add value and functionality to the Bitcoin ecosystem by enabling Ethereum-like smart-contracts, near instant payments and higher-scalability, and this past January after almost two years of development its mainnet dubbed Bamboo was finally launched.

Kernel and Graphics: PDS, VKMS and Nouveau

  • PDS 0.98s release
    PDS 0.98s is released with the following changes 1. Fix compilation issue on raspberry pi. 2. Minor rework and optimization on balance code path. 3. Fix wrong nr_max_tries in migrate_pending_tasks. This is mainly a bug fix and minor optimization release for 4.17. The rework of balance code doesn't go well, it actually make more overhead than current implement. Another rework which based on current implement is still on going, hopefully be included in next release.
  • PDS-MQ CPU Scheduler Revised For The Linux 4.17 Kernel With Minor Optimizations
    Alfred Chen announced this week the release of PDS-mq 0.98s, his latest patch-set of this CPU scheduler against the Linux 4.17 upstream code-base and includes minor optimization work and bug fixes. The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.
  • Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer
    Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events. At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.
  • The State Of The VKMS Driver, Preparations For vBlank & Page Flip Events
    One of the exciting additions to look forward to with the upcoming Linux 4.19 kernel cycle is the virtual "VKMS" kernel mode-setting driver. The driver is still a work-in-progress, but multiple developers are working on it.
  • NIR Continues To Be Prepped For OpenCL Support
    Longtime Nouveau contributor Karol Herbst who joined Red Hat several months ago has been working on Nouveau NIR support as stepping towards SPIR-V/compute support and this summer the work very much remains an active target.
  • Nouveau Gallium3D Moves Closer Towards OpenGL 4.5 Compliance
    While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially. This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.

DistroWatch The Best Website For Distro Hoppers

The DistroWatch features release announcements of new versions of hundreds of Linux and other distributions. It does host reviews of distros, podcasts, and newsletters. DistroWatch first published by Ladislav Bodnar, the founder, and maintainer, on May 31, 2001. DistroWatch initially focused on Linux distributions. But later based on user requests, it went on adding different flavors of operating systems like BSD family, Android x86, Oracle Solaris, MINIX, and Haiku etc. The DistroWatch presents detailed information at one place in a very convenient manner. At the time of writing this article, the DistroWatch hosted information of more than 300 active distributions (referring the list of distros populated under drop-down feature on the first page of the DistroWatch) and more than hundred in queue. It is said that the DistroWatch lives out of advertising and donation. LinuxCD.org is the first to advertise on the DistroWatch site. Read more
