Hands-On: Adventures with Ubuntu Linux on the Raspberry Pi 4

Filed under
Linux
Ubuntu

With the introduction of the Raspberry Pi 4 series, with more than 1GB of memory, it has become much more practical to install and run Linux distributions other than the standard Raspberry Pi OS (formerly known as Raspbian). So it's time for me to give Ubuntu a try again, and see how it goes.

The first part of this task is simply deciding what version of Ubuntu to install – and that is nowhere near as easy as it sounds. Those who are familiar with Ubuntu and the RPi will know that the Ubuntu Mate project has had a Raspberry Pi version for quite some time, while the "official" Ubuntu Raspberry Pi distribution has only come out recently, and is only available for the Raspberry Pi 4. I will be looking at both of these.

LibO

Continuing LibreOffice Shortcuts poster, here's educational poster I made to spread LibreOffice's ODT - ODS - ODP to all people in all countries. These formats are known with the name Open Document Format and these are better than Microsoft's. The goal of this poster is to invite people to change their habits of saving as DOC - XLS - PPT formats into saving as ODT - ODS - ODP formats which are better. This poster is an English adaptation of my Indonesian version few years ago. I encourage you to place this on your schools, offices, websites, blogs, social media, and other places. You are free to adapt and share it with your own language. If you are curious, download LibreOffice application here for Windows, macOS and GNU/Linux. Okay, now let's share once again!

8 Best Free and Open Source Functions-as-a-Service

Filed under
OSS

FaaS (Function-as-a-Service) is a category of cloud computing services. It’s a fairly new development that originated from PaaS. FaaS is a cloud computing model that abstracts server management and low-level infrastructure decisions away from developers, but takes it much further than PaaS. FaaS is a distinct technology. All allocation of resources is managed by the platform, allowing applications to be developed without any thought of implementation, load balancing, or scaling. It allows developers to execute small snippets of code in response to events without having to build complex infrastructure.

FaaS is often known as serverless. FaaS has been gaining popularity. The main advantage of this technology is the ability to create and run applications without the need for infrastructure management. In other words, when using a serverless architecture, developers no longer need to allocate resources, scale and maintain servers to run applications, or manage databases and storage systems.

5 open source alternatives to GitHub

Filed under
OSS

Git is a popular version-control system, primarily used for code but popular in other disciplines, too. It can run locally on your computer for personal use, it can run on a server for collaboration, and it can also run as a hosted service for widespread public participation. There are many hosted services out there, and one of the most popular brands is GitHub.

GitHub is not open source. Pragmatically, this doesn't make much of a difference to most users. The vast majority of code put onto GitHub is, presumably, encouraged to be shared by everyone, so GitHub's primary function is a sort of public backup service. Should GitHub fold or drastically change its terms of service, recovering data would be relatively simple because it's expected that you have a local copy of the code you keep on GitHub. However, some organizations have come to rely on the non-Git parts of GitHub's service offerings, making migration away from GitHub difficult. That's an awkward place to be, so for many people and organizations, insurance against vendor lock-in is a worthwhile investment.

Top Tips to Protect Your Linux System

Filed under
Linux

Linux-based operating systems have a reputation for their high-security level. That's one of the reasons why the market share for Linux has been growing. The most commonly used operating systems such as Windows are often affected by targeted attacks in the form of ransomware infections, spyware, as well as worms, and malware.
As a result, many personal, as well as enterprise users, are turning to Linux-based operating systems such as the Ubuntu-based Linux OS for security purposes. While Linux based systems are not targeted as frequently as other popular operating systems, they are not completely foolproof. There are plenty of risks and vulnerabilities for all types of Linux devices which put your privacy as well as your identity at risk.

  • Tuxera First to Bring Network Bandwidth-Saving SMB Compression Feature to Linux Environments
  • Tuxera First to Bring Network Bandwidth-Saving SMB Compression Feature to Linux Environments

    Tuxera, a world-leader in quality-assured storage management and networking software, announced that the company's SMB server implementation, Fusion File Share by Tuxera, now offers transparent compression to platforms outside of Microsoft Windows. Compression is being rapidly and widely adopted in the storage industry as a feature in memory hardware, file system implementations, and also networking protocols such as Microsoft's server messaging block technology (SMB). The ability to compress files inline during transfer can significantly reduce bandwidth and transfer time. Microsoft released the transparent compression feature to their SMB protocol specification in early 2019. However, Tuxera is the first to implement SMB compression outside of Microsoft Windows, bringing this highly in-demand feature to Linux environments in enterprises around the world.

  • Wake-on-LAN

    With Wake-on-LAN (WoL) it can be slightly easier to manage machines in-house. You can fire up the workstation and start the day’s compile jobs (to catch up with overnight work by the KDE community, say) while drinking an espresso downstairs and doomscrolling.

    [...]

    If all the administrative bits are in place, then the simple way to wake up a machine is wake <hostname>. This requires root, since it sends specially-crafted (broadcast) Ethernet packets, which isn’t something that regular users can do.

  • AMD+SUSE Tackling Frequency Invariance For AMD EPYC 7002 CPUs - Phoronix

    Thanks to work by AMD and SUSE engineers, the Linux kernel could soon be seeing frequency invariance support for EPYC 7002 "Rome" processors for yielding greater performance and power efficiency.

    Over the past year we have seen a lot of Linux kernel work for dealing with frequency invariance but to now that on the x86 side has been focused on Intel Xeon processors. Now through the cooperation of AMD with patches led by SUSE, frequency invariance is being worked on for the EPYC 7002 "Rome" processors.

  • Intel Begins Landing Their Open-Source Vulkan Driver Ray-Tracing Support

    This week marked the release of Vulkan 1.2.162 with the ray-tracing extensions now finalized. As such Intel's stellar open-source team has begun landing their work around Vulkan ray-tracing ahead of the Xe HPG hardware availability that will support this functionality.

    Back in October I wrote about Intel preparing their open-source driver support for Vulkan ray-tracing ahead of Xe HPG and now with the updated Vulkan spec out there they are able to push more of their work.

  • Support UserFreedom by purchasing gifts from the GNU Press Shop

    To celebrate this year's thirty-fifth anniversary of the FSF, we designed and issued an extremely cool undersea-themed 35th Anniversary T-shirt. The initial run sold out faster than a weekend scuba diving trip, but we've reprinted them in a new color scheme worthy of Neptune himself -- lots of these are in stock and ready to send to you.

    But that's not all! So excited are we on the occasion of FSF's coral anniversary that we also made new socks. Warm your toes with the brand new FSF thirty-fifth anniversary socks -- crew-length socks whose coral, black, and blue color scheme will match your FSF 35th Anniversary Poster. Orders for these limited edition socks will be accepted on a "pre-order" basis until December 9th -- we'll collect customer orders, then print the socks, which I'll then ship to you. Be sure to order socks within the above time frame if you want them, because we won't have a lot of surplus after the orders are filled.

    [...]

    Finally, a note about shipping. The current pandemic places a lot of obstacles to buying and selling merchandise at FSF, so your order may be shipped less punctually than before -- but it absolutely will be shipped. This time of year, many customers place orders hoping to have them in hand by December 25. If this is you, and you are in the United States, please place your order before December 4, in order to provide us with the necessary lead time to make sure that your gifts are shipped on time. In any circumstance, it's advisable to place any order as soon as you can; I will endeavor to ship it as promptly as circumstances permit. As always, don't hesitate to email sales@fsf.org with any questions or concerns about shipping, inventory, payment, suggestions for future items for sale, or anything else -- this email address is the first thing I check every work day, especially at this time of year.

  • Presenting Cockpit Wicked | YaST

    If you are into systems management, you most likely have heard about Cockpit at some point. In a nutshell, it offers a good looking web-based interface to perform system tasks like inspecting the logs, applying system updates, configuring the network, managing services, and so on. If you want to give it a try, you can install Cockpit in openSUSE Tumbleweed just by typing zypper in cockpit.

    [...]

    Cockpit already features a nice module to configure the network so you might be wondering why not extending the original instead of creating a new one. The module shipped with Cockpit is specific to NetworkManager and adapting it to a different backend can be hard.

    In our case, we are trying to build something that could be adapted in the future to support more backends, but we are not sure how realistic this idea is.

  • PHP 8.0 Ready To Ship With Many New Features, Even Better Performance - Phoronix

    PHP 8.0 is scheduled for release tomorrow on the US Thanksgiving day. PHP 8.0 brings with it many new language features on top of the opt-in JIT compiler support. Here is a look at some of the PHP 8.0 changes along with a quick look at the near final performance of PHP 8.0 on an AMD EPYC Linux server.

    PHP 8.0 is a very worthy successor to last year's PHP 7.4. Besides the JIT compiler there is a ton of work incorporated into this big version bump. Among the PHP 8.0 highlights are:

    - PHP8 introduces the much anticipated Just In Time (JIT) compiler for further enhancing the speed of PHP scripts. More details on PHP's JIT compiler via this Wiki page.

Here’s some tips to learn web development using your Android knowledge.

  • Software Diagrams Aren’t Always Correct and That’s OK

    Concretely, software is just bits in electronic storage that control and/or are manipulated by processors. Abstractions are the building blocks that enable humans to design and build complex software systems out of bits. Abstractions are products of out minds—they allow us to assign meaning to clusters (some large, some small) of bits. They allow us to build software systems without thinking about billions of bits or how processors work.

    We manifest some useful and generally simple abstractions (instructions, statements, functions, classes, modules, etc.) as “code” using other abstractions we call “languages.” Languages give us a common vocabulary for us to communicate about those abstract building blocks and to produce the corresponding bits. There are many useful tools that can and should be created to help us understand the code-level operation of a system.

    But most systems we build today are too complex to be fully understood at the level of code. In designing them we must use higher-level abstractions to conceptualize, compose, and organize code. Abstract machines, frameworks, patterns, roles, stereotypes, heuristics, constraints, etc. are examples of such higher-level abstractions.

    The languages we commonly use provide few, if any, mechanisms for directly identifying such higher-level abstractions. These abstractions may manifest as naming or other coding conventions but recognizing them as such depends upon a pre-existing shared understanding between the writer and readers of the code.

  • How To Install PyCharm on Debian 10

    In this tutorial, we will show you how to install PyCharm on Debian 10. For those of you who didn’t know, PyCharm is an intelligent and fully-featured IDE for Python developed by JetBrains. It also provides support for Javascript, Typescript, and CSS, etc. You can also extend PyCharm features by using plugins. By using PyCharm plugins you can also get support for frameworks like Django, Flask. We can also use PyCharm for other programming languages like HTML, SQL, Javascript, CSS, and more.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of PyCharm on a Debian 10 (Buster).

OSS

A headless CMS (content management system) is a backend system which works the content available through API (RESTful API or GraphQL). It's built to give the developers the possibilities to create what they want.

The API-driven headless approach is trending right now especially for enterprise users and developers.

Headless CMS programs can be used as a backend for mobile apps, static generated websites with frameworks like Next, Nuxt, Gridsome and Hugo which also supports server-side rendering. They can be also used to manage IoT (Internet of Things) applications.

    In our conversation about The Future of Stuff with its author Vinay Gupta, we discuss the founding role of Free Software in the digital world. We'll also talk about the need to list and protect human rights that were barely imaginable in the old physical world—and the radical ways we might make that happen. Vinay is the founder of Mattereum, a London-based fintech company using legally-enforceable smart contracts to enable the sale, lease, and transfer of physical property and other legal rights. He is a technologist and policy analyst interested in how specific technologies can close or create new avenues for decision-makers. This interest has taken him through cryptography, energy policy, defense, security, resilience, and disaster management arenas. He is perhaps best known for his work on the Hexayurt Project, a public domain disaster relief shelter designed to be built from commonly-available materials, and Ethereum, a distributed network designed to handle smart contracts.

ZDNet and Linux often provide a good chance for a laugh

The site's security writer, Catalin Cimpanu, has form [1, 2, 3] in screwing up when he writes about Linux. And ZDNet has a person on staff, Stephen J. Vaughan-Nicholls, who knows the Linux very well. So why exactly the kind of dross that was published on 24 November was ever allowed to pass the editor's knife is puzzling.

To details. In this case, Cimpanu was writing about a botnet known as Stantinko, a new version of which has apparently been detected by the Israeli security firm Intezer and detailed in a blog post which was shared with Cimpanu before being made available to world+dog.

Before I go any further, let me say that i have reported on Intezer at least thrice, and they are sound when it comes to their research. There is no hyperbole and when they say something, they have enough evidence to do so.
