  • Understanding Horizontal Pod Autoscaler

    Auto-scaling is a way to automatically increase or decrease the number of computing resources that are being assigned to your application based on resource requirement at any given time. It emerged from cloud computing technology, which revolutionized the way computer resources are allocated, enabling the creation of a fully scalable server in the cloud.

    What is the HPA?

    HPA or Horizontal Pod Autoscaler is the autoscaling feature for Kubernetes pods. HPA offers the following advantages: economic solution, automatic sizing can offer longer uptime and more availability in cases where traffic on production workloads are unpredictable. Automatic sizing differs from having a fixed amount of pods in that it responds to actual usage patterns and therefore reduces the potential disadvantage of having few or many pods for the traffic load. For example, if traffic is usually less at midnight, a static scale solution can schedule some pods to sleep at night, on the other hand, it can better handle unexpected traffic spikes.

  • This is how I surf the Internet

    Aside from a handful of pinned tabs, I open a new tab for anything I need to do: search the web, file a bug, look up documentation, check on the news, the weather, you get the idea. I am also addicted to Firefox’s new tab page, so I’ll often open a new tab out of boredom to let Pocket suggest an article for me. I hardly ever look at the same tab twice. If I need to get to something, it is never worth digging through all those tabs, I’ll just type what I am looking for in a new tab, and hope for a good suggestion from the awesomebar. After a couple of days I’ll have hundreds of tabs open. I declare “tab bankruptcy”, I purge them all, and start over.

    A while ago I made an addon for myself. It was essentially a tab FIFO. It would only allow 10 tabs to be open at a time. If an 11th tab was created, the least recently activated tab would be closed.

  • Unsplash Launches Official Plugin for WordPress

    Unsplash has released its own official plugin for WordPress, co-developed with the team at XWP. The plugin seamlessly connects Unsplash’s 1 million+ free high-resolution image library with the WordPress editor.

    [...]

    Instant Images, a plugin that boasts one-click Unsplash uploads, is currently the largest competitor to the adoption of the official plugin with more than 50,000 active installs. Many other plugins have also added some form of Unsplash integration in the past. Chesser said his team has loved seeing the variety of applications developers have created with their API and they were hesitant to create their own plugin.

  • [LibreOffice GSoC] Week 7 Report by Ahmed ElShreif

    The last week was the 7th week of coding weeks in GSoC program. I continued adding support for the non supported items.

  • Google Summer of Code 2020 - Post 6

    I updated the user interface of the Rocs graph layout plugin. Now, each layout algorithm corresponds to a tab. See below the tab for the Radial Tree Layout.

    [...]

    The root vertex can be selected by the user or determined automatically. Currently, a center of the tree is used for automatic root selection. The user can also control the distance between nodes by changing the node separation. Tomorrow I will finish the tests and add some code to check if the graph being laid out is a tree.

    Note: I decided to change the title of my GSoC posts to reflect the fact that I am not being able to follow a weekly schedule.

More on Cooler Master

  • Cooler Master are doing a slick Kickstarter-exclusive Raspberry Pi 4 case

    Need a good sturdy case for your favourite little mini-PC? Cooler Master think they have something that will interest you with the Cooler Master Pi Case 40.

    It's a Kickstarter exclusive, meaning they're using the crowdfunding platform as a place to order it and that will be the only place you're able to grab yourself one. It's designed to be a 'long lasting, premium enclosure for Raspberry Pi 4 pro users' giving you a durable shell that protects, keeps it cool and offers a number of pretty sweet sounding additional features baked right into it. They're also saying it will be super quiet even under 'heavy' overclocks, because of the thermal design so you don't need a fan.

Calculate Linux 20th Anniversary: Consistent by Design

Calculate Linux is an impressively different Linux operating system. This is a distribution designed with home and SMB users in mind. It has expanded its user interface into an appealing selection of desktop choices over the years. Calculate is particularly appealing to small businesses that want a rock-solid system with the flexibility to meet a variety of needs. It is optimized for rapid deployment in corporate environments. It can also be an inviting computing option for consumers with a bit of Linux know-how under their belts. Calculate is not difficult to use. But it is a bit different under the hood, especially in how its package management system works. Calculate comes in a smart collection of some of the best desktop environments. That adds to its appeal because it is not a distro with one size having to fit all users. It comes in KDE Plasma, Cinnamon, LXQt, MATE, and Xfce editions. A community edition gives you an added choice for a nicely-tweaked GNOME 3 desktop. All are rolling-release distribution sets. That means you install it once and just apply the updated packages as they are released. You never have to reinstall a major release. The latest update, version 20.6, released on June 21, is a hallmark edition of sorts. It marks Calculate Linux’s 20th year. Read more

IBM/Red Hat: ApacheDS LDAP, OpenEEW, Command Line Heroes

  • Secure authentication with Red Hat AMQ 7.7 and ApacheDS LDAP server

    In this article, we will integrate Red Hat AMQ 7.7 with the ApacheDS LDAP server. However, any version of the AMQ 7.x series can be integrated with the steps mentioned in this article. For this example integration, we’ll use Apache Directory Studio, which is an LDAP browser and directory client for ApacheDS. You will learn how to set up the ApacheDS LDAP server from scratch, and how to integrate the new LDAP configuration changes that are required in AMQ 7.7. Finally, we’ll test the integration with an AMQ 7.7 shell-based client, using Hawtio as a graphical user interface (GUI). This will be helpful to system administrators and developers as they can quickly create a proof of concept for LDAP and AMQ integration. This will help in enabling role-based access control(RBAC) for accessing AMQ 7.7.

  • IBM-backed Grillo open sources earthquake early-warning system through The Linux Foundation

    Earlier today, The Linux Foundation announced it will host a new initiative to accelerate the standardization and deployment of earthquake early-warning (EEW) systems for earthquake preparedness around the world. Created by Grillo with support from IBM, USAID, the Clinton Foundation, and Arrow Electronics, the OpenEEW project includes the core components of the Grillo EEW system composed of integrated capabilities to sense, detect, and analyze earthquakes and to alert communities. IBM was originally connected to Grillo through the Clinton Foundation at a convening of the Clinton Global Initiative (CGI) Action Network. Now, IBM is assisting Grillo by adding the OpenEEW earthquake technology into the Call for Code deployment pipeline supported by The Linux Foundation. We sat down with Call for Code Chief Technology Officer Daniel Krook and IBM Developer Advocate Pedro Cruz to learn more about OpenEEW.

  • IBM, Grillo, and the Linux Foundation partner on early earthquake detection systems

    The Linux Foundation — in partnership with IBM and startup Grillo — today announced an initiative called OpenEEW to accelerate the deployment of open source earthquake early warning (EEW) detection systems around the world. The organizations say OpenEEW will incorporate sensing, detection, and analysis components from Grillo’s EEW platform, along with a Docker software version of the detection component that can be deployed to Kubernetes and Red Hat OpenShift on IBM Cloud. An estimated 3 billion people live with the threat of earthquakes globally. According to the U.S. Geological Survey, in California, there’s a 94% chance that an earthquake will not be just a foreshock. Yet only a few countries — like Mexico, Japan, Turkey, Romania, China, Italy, portions of the U.S., and Taiwan — have EEWs, in part because they can cost upwards of $1 billion.

  • The Linux Foundation, Grillo and IBM Announce New Earthquake Early-Warning Open Source Project

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced it will host Grillo’s OpenEEW project in collaboration with IBM to accelerate the standardization and deployment of earthquake early-warning systems (EEWs) for earthquake preparedness around the world. The project includes the core components of the Grillo EEW system comprised of integrated capabilities to sense, detect and analyze earthquakes as well as alert communities. OpenEEW was created by Grillo with support from IBM, USAID, the Clinton Foundation and Arrow Electronics. Earthquakes often have the most severe consequences in developing countries, due in part to construction and infrastructure issues. Timely alerts have the potential to help save lives in the communities where earthquakes pose the greatest threat. EEW systems provide public alerts in countries including Mexico, Japan, South Korea and Taiwan, but nearly three billion people globally live with the threat of an earthquake and don’t have access to nation-wide systems, which can cost upwards of one billion U.S. dollars. OpenEEW wants to help reduce the costs of EEW systems, accelerate their deployments around the world and has the potential to save many lives. “The OpenEEW Project represents the very best in technology and in open source,” said Mike Dolan, Senior Vice President and GM of Projects at the Linux Foundation. “We’re pleased to be able to host and support such an important project and community at the Linux Foundation. The open source community can enable rapid development and deployment of these critical systems across the world.”

Kernel: Linux 5.9 Features and Linux Plumbers Releasing More Passes

  • Intel Adds Capability To Linux 5.9 For NVDIMM Firmware Updates Without Reboots

    For Intel NVDIMMs like DC Persistent Memory there is support on the way with Linux 5.9 to support firmware updates to the non-volatile memory device without the need for a system reboot.  The LIBNVDIMM changes for Linux 5.9 include "Runtime Firmware Activation" as the Intel-devised feature for accommodating device firmware updates to supported NVDIMM modules without needing a reboot. The intent is on being less disruptive than a reboot and allow loading the firmware still via the ndctl user-space utility and then the new ability to "activate" the new firmware. 

  • F2FS With Linux 5.9 Adds Secure TRIM, New Garbage Collection Option

    The Flash-Friendly File-System (F2FS) changes have been sent in for the in-development Linux 5.9 kernel.  The prominent changes this cycle include a new garbage collection mode (GC_URGENT_LOW) and a "secure" TRIM option (F2FS_IOC_SEC_TRIM_FILE) in the name of security.  The F2FS_IOC_SEC_TRIM_FILE functionality is intended as secure erase functionality. For drives not supporting TRIM/DISCARD, zeroing out the given data range for the regular file is performed to ensure the data is wiped on disk. 

  • Linux 5.9 Bringing Mellanox VDPA Driver For Newer ConnectX Devices

    There are a few changes worth mentioning out of the VirtIO updates submitted today for the Linux 5.9 kernel.  The latest Mellanox driver going mainline in the Linux kernel is a VDPA (Virtual Data Path Acceleration) for their ConnectX6 DX and newer devices.  The VDPA standard is an abstraction layer on top of SR-IOV and allows for a single VirtIO driver in the guest that isn't hardware specific while still allowing wire-speed performance on the data plane. VDPA is more versatile than the likes of VirtIO full hardware offloading. More details for those interested via this Red Hat post.

  • Linux Plumbers Releasing More Passes

    After a careful review we have decided to release more passes. We are thrilled with the interest for this first ever online Linux Plumbers. The highlight of Linux Plumbers is the microconferences which are heavily focused on discussion and problem solving. To give the best experience for discussion, we have chosen to use an open source virtual platform that offers video for all participants. The platform recommends not having more than a certain number of people in each room at a time, hence putting a cap on registration to avoid hitting that limit. We do have solutions that will hopefully allow as many people as possible to experience Plumbers. We appreciate your patience and enthusiasm.
