Linux

ah-ha! That's why Korora

Filed under
Linux

When Kororaa changed their name to Korora I wondered why? But today I think I've spotted the real reason.

Time for a discreet OSX feature to come over to Linux.

Linux

There is functionality in OSX called Airdrop which Linux Desktops could do with as a replacement of the SMB/NFS shared files sharing system. There are some options out with but they are seemingly stale projects which however can provide the functionality which is needed in Linux

The question is, Which OS is the best? The replies were interesting.

Filed under
Linux

asking this very simple question which is the best Operating system in some corners of the Internet, is like throwing a slab of raw meat into a wild animal enclosure and watching as the question gets ripped apart. Its tantamount to asking which religion or political system is the best in the way some will tear strips off others

The rest here...

Is OpenSuse a viable Ubuntu alternative?

Filed under
Linux

There’s lots of forums and even 3 or 4 releases in I still hear people talking about how much they dislike Unity, which is a shame because it’s turning into quite a nice Gui from where i’m sitting, however one thing Linux has is choice. If nothing else there are other solid, stable distributions out there which offer a user a good solid alternative. Once such example is maybe OpenSUSE.

Nettop, the command not the hardware is not just for OSX..

Filed under
Linux

I found this article on the osxdaily website, the article refers to running nettop on OSX however it’s a *nix command so will also be in the package repository (if not preinstalled) on your favorite distro. I’ve tested all of the command options on Sabayon and they work fine..

HOW TO DO MASS ENROLLING OF YUBIKEY WITH LINOTP

Filed under
Linux

While you may have your Ubuntu install locked down with Full disk encryption incase you loose the laptop, UFW locking down the network with a firewall, there is no point if you have a poor password. Dual factor authentication using One Time Passwords may be an option for you, if they are this great howtoforge article might point you in the right direction.

I've been playing Half-Life recently, something to which I've looked forward for quite some time. I did get it playing under Wine years ago, but I thought I only got a little ways. I'm stuck In the Rails right now, but I remember this level.

Getting Squid3 on Debian 6.x to work with Active Directory, Security Groups and Websense

Filed under
Linux

I’ve had a need to get a local squid proxy to perform local filtering based on AD Security groups because it’s not something websense can do. I found this wonderful howtofoge guide online and Used it to setup the base system. This howto is a work in progress as the next stage is to get it working with DansGuardian or SquidGuard.

Prerequisites
Client Internet Explorer Browsers need to have “Enable Integrated Windows Authentication” ticked in Internet Options :: Advanced settings as well as Proxy Auto detection enabled – google these if not sure. All modern web browsers will support proxy auto detection. Firefox and Chrome also support Windows Authentication.

Enabling Dual Factor Authentication on Linux SSH logins..

Filed under
Linux

A couple of weeks ago I wrote a post on using a Chromebook to develop on a cloud platform. Its based on a Digital Ocean remote server and like most people who wish to attach to the command line interface on a remote server I use SSH. It’s an encrypted connection over the network/internet from end to end. However being a cloud server I was wondering if it was possible to secure this a little bit more?

A chat with a friend on the way into work provided me with a solution.

The solution is Two Factor authentication a system beased on a simple premise, something you know (the SSH password in this case) and something you have (your mobile phone in this case, but it could be a secure token) which will deliver a random number.

Kernel Work and Graphics

  • Reiser5 File-System Working On New Features Like Data Tiering, Burst Buffers

    Reiser5 was announced back on New Year's Eve with support for local volumes and supporting parallel scaling out and other improvements over the long-in-development but never mainlined Reiser4. While Reiser5 was not met with enthusiasm, Edward Shishkin has continued working on this next-generation file-system and today announced the latest round of improvements. Shishkin announced today with support for dumping peaks of I/O load to a proxy device with Reiser5, "Now you can add a small high-performance block device to your large logical volume composed of relatively slow commodity disks and get an impression that the whole your volume has throughput which is as high, as the one of that "proxy" device!"

  • Steam Beta adds Vulkan shader processing

    Valve has enabled the next step towards making Steam games on Linux run smoother in the latest Steam Beta release. This is something Valve has been working towards for some time now, as the Steam Client has been able to download pre-compiled GPU shaders, which you might have seen when something pops up in your Steam Downloads with an OpenGL and Vulkan icon below. [...] It doesn't just do it for installed games, it will do it as you're downloading them too, so by the time you've finished downloading it might even be all ready.

  • Adaptive-Sync/VRR Seeing Port To xf86-video-modesetting Driver

    Currently if wanting to use Adaptive-Sync/FreeSync variable refresh rate support of the AMDGPU DRM kernel driver you need to be using the xf86-video-amdgpu X.Org driver for proper handling as well, but a port of the DDX bits to the generic xf86-video-modesetting driver is in the works. This is still obviously contingent upon the DRM kernel-side support in the AMDGPU DC code, but for those using this generic DDX driver, it at least allows the Adaptive-Sync/VRR handling there.

Plasma Mobile update: April-May 2020

It’s been a while since the last status update on Plasma Mobile, so let’s take a look at what happened since then. To assist new people in contributing, we organized a virtual mini Plasma Mobile sprint in April. During the three days, we discussed many things, including our current tasks, the websites and documentation, our apps and many other topics. Most of our important tasks have been asigned to people, many of them have been implemented already. On Saturday, there was a training day, with four training sessions on the technology behind Plasma Mobile... Read more

GNU/Linux and Arduino in Devices/Embedded and Open Hardware

  • ODYSSEY expandable mini PC supports Win10, Linux and Arduino

    A versatile new mini PC is now available to order in the form of the ODYSSEY X86J4105864, offering an easy way to build Edge Computing applications with powerful CPU and rich communication interfaces, say its developers. The ODYSSEY X86J4105 mini PC is based on Intel Celeron J4105, is a Quad-Core 1.5GHz CPU that bursts up to 2.5GHz. There is also an onboard ATSAMD21 Core, an ARM Cortex-M0+ MCU that allows you to program Arduino on the x86 platform.

  • What is ESP32 and Why Is It Best for IoT Projects?

    ESP32 is a low-powered, low-cost microcontroller (MCU) board, with both Wi-Fi and Bluetooth built in, and is based on a dual-core processor mechanism. The first one is a powerful processor, such as a Xtensa LX6 (~240 MHz) with 512 KiB memory and the second an ultra-low coprocessor (ULP) with only 8 KiB memory designed to run when ESP32 is in deep-sleep mode. Other components include around 48 I/O pins (variable); an array of peripheral interfaces including temperature, hall effect, and capacitive touch sensors; and an 8-centimeter LCD panel, prominently visible here in an ESP32-WROVER board by Espressif Systems. [...] In fact, it runs on FreeRTOS, a leading operating system supported by Arduino. A big advantage of ESP32 is that it is readily supported by Arduino IDE as a “shield” which can be accessed from Board Manager. One can easily use functions from the FreeRTOS libraries when coding for the ESP32 within the Arduino IDE. Considering the scale of ESP32 applications which could be tiny, coin cell devices, it is better to use a predictable memory OS such as FreeRTOS rather than have its own complete OS, which is supported by Raspberry Pi, for example.

  • Kiwi TCMS is partnering up with Pionir

    We are happy to announce that Kiwi TCMS is going to partner with Pionir on the development of open source hardware for testers! Pionir is a free school focused on creating a new generation of digital leaders, an exponential culture and solving challenges using technology. They are located in Kikinda, Serbia. [...] Pionir will be developing hardware black boxes for teaching exploratory testing in cooperation with Kiwi TCMS. We have dedicated €2000 from our bounty program for students of the free school towards completing this project.

    The goal of the project is to produce at least 3 boxes and reference designs that will serve as a didactic tool for teaching, but also be free and open hardware, and as such, available to everyone to build from source. This project will be trusted to the students of the free school who will get opportunity to take part in the challenging process of building a digital appliance, from designing the machine logic, to develop and prototype hardware.

    The project includes designing, assembling, programming, documenting and delivering this hardware to us! Everything is expected to be open source: list of components, assembly instructions, 3D design files, source code, documentation and instructions! Our goal is that this will be relatively cheap and easy to build so everyone else can build their own boxes. During the next several months there will be new repositories created under https://github.com/kiwitcms to host the various boxes.

  • Daniel Stenberg: curl ootw: –socks5

    --socks5 was added to curl back in 7.18.0. It takes an argument and that argument is the host name (and port number) of your SOCKS5 proxy server. There is no short option version.

  • How does the Glean SDK send gzipped pings

    Within the Glean SDK, the glean-core Rust component does not provide any specific implementation to perform the upload of pings. This means that either the language bindings (e.g. Glean APIs for Android in Kotlin) or the product itself (e.g. Fenix) have to provide a way to transport data from the client to the telemetry endpoint. Before our recent changes (by Beatriz Rizental and Jan-Erik) to the ping upload system, the language bindings needed to understand the format with which pings were persisted to disk in order to read and finally upload them. This is not the case anymore: glean-core will provide language bindings with the headers and the data (ping payload!) of the request they need to upload. The new upload API empowers the SDK to provide a single place in which to compress the payload to be uploaded: glean-core, right before serving upload requests to the language bindings.

  • Create interactive content in WordPress with the H5P plugin

    WordPress is best known as a website content management system, but it also a great learning management system (LMS) for delivering online courses. If that is what you are looking for out of WordPress, then H5P should be the top plugin on your list. H5P is a way to create and share interactive HTML5 content, including presentations, games, quizzes, forms, and more, in a browser. You can download a wide variety of content types from H5P's Examples and Downloads page, or you can create unique content to embed in your WordPress site. H5P provides plugins and integrations for WordPress, Moodle, Drupal, Canvas, Brightspace, Blackboard, and more. In this article, I will show how to use H5P in WordPress to create a reading comprehension quiz for students.
