Configuring Ansible

Wednesday 20th of November 2019 01:30:03 AM
In a previous article, I covered Red Hat Ansible basics and installed Ansible, creating one control node named RHEL8 and four managed nodes (node1, node2, node3, and node4), all running Red Hat Enterprise Linux. Now, for Ansible to communicate with a managed node, you need to configure the control node and the managed nodes with a user account, and give that user account privilege escalation to run commands without having to enter a password.

Linux device mapper writecache

Tuesday 19th of November 2019 11:26:59 PM
Solid State Drives (SSDs) brought performance to the forefront of computing technologies, and their adoption is increasing not only in the data center but also in consumer-grade products. Unlike its traditional spinning hard disk drive (HDD) counterpart, SSDs comprise a collection of computer chips (non-volatile NAND memory) with no movable parts. Therefore SSDs are not kept busy seeking to new drive locations and, in turn, introducing latency. As great as this sounds, SSDs are still more expensive than HDDs. HDD prices have settled to around $0.03/GB; SSD prices vary but sit at around $0.13-$0.15/GB. At scale, that price gap makes a world of difference.

Cheat sheet for Linux users and permissions

Tuesday 19th of November 2019 01:44:20 PM
The Linux operating system is a true multi-user OS, meaning it assumes that there's data on every computer that should be protected, whether in the interest of privacy, security, or system integrity. Linux uses file ownership and permissions to manage file and folder access. For administrators who deal with different user environments all day, this system is easy to understand, calculate, and control.

Moving the Home folder to another partition in Ubuntu

Tuesday 19th of November 2019 09:38:12 AM
Usually when you have Ubuntu installed, it is likely that the system folders and the home folder all belong to the same partition.In order to keep your custom settings, your files and folders, it is recommended that you put your home folder in a specific partition so that future alterations on the system files and folders will not have any effect on the home folder so that you would be able to upgrade or even reinstall your Ubuntu without damaging the current custom files configuration.

  • Linux 5.5 To Finally Expose NVMe Drive Temperatures Via HWMON

    Linux for years has supported monitoring NVMe drive temperatures when installing the nvme user-space utility and run as root, etc. But now finally with Linux 5.5 the kernel is supporting NVMe drive temperature reporting through the hardware monitoring "HWMON" infrastructure alongside other hardware sensors. Come the Linux 5.5 stable release in early 2020 is the NVMe HWMON support to allow reporting the current NVMe drive temperature sensor(s) and min/max thresholds via this kernel infrastructure. This in turn allows user-space to simply query the data over sysfs without the need for any utilities, no root requirement, and should gracefully work with the various programs that report HWMON sensor readings to Linux desktop users.

  • PHP 5.3 To PHP 7.4 Performance Benchmarks On AMD EPYC

    With the big PHP 7.4.0 release due out next week, yesterday we published our PHP 7.4.0 benchmarks using the near-final build for this annual update to PHP. Those benchmarks compared previous releases as far back as PHP 5.6. But out of curiosity after that article I went to do some benchmarks going back to PHP 5.3 through PHP 7.4 and PHP 8.0-dev. With the AMD EPYC 7642 server running Ubuntu 19.10 used in yesterday's article, I ran the final PHP 5.3/5.4/5.5 benchmarks added in to yesterday's data. So for those curious how the historical PHP5 performance compares to the imminent PHP 7.4, these benchmarks are for your enjoyment today.

  • Wine Patches Coming To Allow UMIP Emulation - Works Around Issues For Ryzen 3000

    Coming up this weekend with the Linux 5.4 kernel is emulation/spoofing of the SGDT/SIDT/SMSW instructions around UMIP for allowing newer 64-bit Windows games to run on Wine and Steam Play (Proton). With newer CPUs like the AMD Ryzen 3000 series that support UMIP, these instructions are not allowed to run in user-space with Wine due to UMIP. So while the first stable kernel release is about to land with this support, some Wine-based emulation not contingent on the kernel patches is also in the works.

  • KF6 Sprint - Day One

    Today we started our KF6 sprint at the MBition office in Berlin. Beside the people attending in person, we have David Faure joining us via web conference. Thanks already to the people at MBition that spend time on making it possible to host the sprint there. First stuff to be discussed were some high level things, like does the monthly release scheme work out well. Short answer: yes :) The short period works well, allows people to fix issues directly in frameworks and still have that reasonable fast provided to the users. And the overhead of release creation is low, thanks to automation.

  • Goldman Sachs is planning on giving some of its most valuable software to Wall Street for free

    Goldman Sachs wants to give away some of its most valuable software. The investment bank spent countless hours over 14 years developing a platform called Alloy to help it access and analyze the growing set of financial databases being created across the firm. Now Goldman is taking the unusual step of making that program, as well as the language underlying it, available to the rest of Wall Street for free as open-source software in collaboration with a nonprofit called Finos. The software and language "have grown to become critical tools within our firm across the trade lifecycle that help us price, assess and evaluate risk, clear transactions, and perform regulatory reporting," said Neema Raphael, co-chief data officer at Goldman. By making it publicly available, "we'll unlock tremendous value for the industry when we co-develop and share models."

  • Open source transparency comes to root of trust hardware

    Geopolitics have put enterprise data centers in the crosshairs of international espionage. From all corners of the globe, hackers of all sorts, including those aligned with national spy agencies, are zeroing in on hardware roots of trust. For any computing platform, the root of trust is the ultimate line of defense against cybersecurity attacks. No matter how secure your operating system and applications appear to be, they are acutely vulnerable if running on a hardware platform whose root of trust has been compromised by an unauthorized party.

  • Cloud Print becomes the latest product to face Google death squad

    At the end of 2020, after over a decade in beta, Google will pick up its product-ending shotgun and take Cloud Print for a talk behind the back shed, from which it will never return. "Beginning January 1, 2021, devices across all operating systems will no longer be able to print using Google Cloud Print," Google said in a support note. "We recommend that over the next year, you identify an alternative solution and execute a migration strategy." Last week for its own Chrome OS operating system, Google added CUPS printing, which it will use instead of Cloud Print.

  • Google shuts down its Cloud Print service after 10-year Beta

    Google revealed plans to shut down Cloud Print, a cloud-based printing solution, at the end of 2020 permanently. The company launched Cloud Print back in 2010 as a solution to print from any Internet connected device to compatible printers. The main benefit of the solution was that users did not have to install printer drivers on their client devices and that devices did not need to be in the same local network as the printer. The solution enabled printing on devices without official support from the printer's manufacturer or drivers for that particular device. On Windows users could install the Google Cloud Printer application to add cloud printing functionality to the operating system.

  • Google Cloud Print will be shut down on December 31, 2020

    After offering printing from any device, from any location, to any web-connected printer with Cloud Print, Google is shutting down the service that has technically been a beta product since 2010. Cloud Print will be gone by the end of next year and users will need to find an alternative before December 31, 2020. Chrome OS, which originally relied on Cloud Print entirely for printing needs, eschewing the need to develop native printing controls, is now going full native. Chrome OS already handles some administrative tasks for printers that use the Common Unix Printing System (CUPS). Google promises to expand administrative options through the end of the year, and add more robust support for external print servers and other security policy administration in 2020. Since Chrome OS and its apps relied entirely on Cloud Print, Google will also be developing APIs for third-party developers to handle printing tasks.

Why You Should Be Using Linux

How many times have you been happily working away when, out of nowhere, Windows either forced a reboot to update, stopped responding, or completely crashed? With Linux, those events are a thing of the past. Because of the way Linux was designed, you (the user) have complete control over nearly everything. Say, for example, an application fails on you. Instead of that application taking the entire desktop along for the ride (an issue that often stumps even software development providers), you can log into what’s called a virtual console and force that crashed application closed via the command line. Yes, that does take a bit more skill than the average user possesses, but once you know how it’s done, it becomes second nature. The likelihood of that actually happening, however, is low. The few instances where this has happened to me was due to my using beta or “nightly” releases of software, which the average user wouldn’t be working with. Linux simply works and works with an almost unheard of reliability. Read more

Industrial-grade Linux OS gets Over-the-Air updates

Modern embedded systems need a reliable and secure way to deliver software updates remotely. Toradex aims to accomplish this by publishing critical operating system updates to customers with devices running TorizonCore, an easy-to-use industrial-grade Linux OS. The system will provide full control over which updates and when these updates are pushed to their devices by way of a web interface. Additionally, customers will be able to push their own updates to their devices using the same OTA system. Managing deployed devices is made easy by providing a high-level view of all devices and their current status. Grouping devices together into fleets is supported and makes managing updates for many devices easy. Every device publishes information up to the server which can prove useful for evaluating device health, inconsistencies in deployed devices, etc. Read more

  • YaST Team: Highlights of YaST Development Sprints 88 and 89

    A few weeks ago, we wrote about the new ItemSelector widget that is finding its way into YaST user interfaces. It turned out that just a simple on/off status is not enough in some cases, so we had to extend that concept. For example, software modules may have dependencies, and we want to show the difference between one that was explicitly selected by the user and one that was auto-selected because some other software module requires it. This kind of shook the foundations of the underlying classes; all of a sudden a bit is no longer just a bit, but it needs to be broken down into even smaller pieces. Well, we cheated; we now use integer values instead. Most of the class hierarchy still only uses 0 and 1, but the new YCustomStatusItemSelector also supports using higher numbers for application-defined purposes. For each possible status value, the application defines the name of the icon to be displayed (for graphical UIs like the Qt UI), the text equivalent (for text mode / the NCurses UI), and an optional nextStatus which tells the widget what status to cycle to when the user changes the status of an item with a mouse click or with the keyboard. A value of -1 lets the application handle this. So this is not a one-trick-pony that is useful only for that one use case (the software modules), but a generic tool that might find good uses in other places all over YaST as well.
