We keep receiving additional information from informed individuals. What we show here isn’t being shown elsewhere, so we’re in no rush to release it quickly and we’d rather do it patiently and correctly (accurate explanations). “Much of the redaction won’t be of fine details or sensitive information; rather, it’s about names as we don’t wish to admonish or embarrass the wrong people.”In previous parts (please refer back to introduction, Part_I, Part_II, Part_III, Part_IV, and Part_V because we’d rather not repeat what was already shown) we presented several frustrating details about Intel’s (mis)handling of Linux. Have a look at this, which ought to be quite a giveaway in visual form: 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Intel_Windows⦈_ Our intention is to redact names and release all the relevant material by this series’ end (it keeps getting longer as more people speak to us). In the video it is possible that redaction will be a little less lenient; we suppose fewer people watch the videos than study the images and by conservative estimates the risk of retribution based on something in a video frame is vastly lower than in text or images. Much of the redaction won’t be of fine details or sensitive information; rather, it’s about names as we don’t wish to admonish or embarrass the wrong people. So if a name shows up, we won’t read it out loud. It might not be occluded, either. “I think the closest hint at Intel’s double agenda is the fact that they decided to launch a Lakefield processor and platform that explicitly targets Windows, as if the whole GNU/Linux revolution over the past 3 decades hasn’t happened at all,” told us a person who knows Intel from the inside. MinceR asserts that “maybe different suits at Intel have different agendas…” The Intel insider said “we discussed this a few months ago, but for me it was a sign that they don’t actually care or it was a confirmation of their renewed interest in promoting Windows…” MinceR asserts that “maybe the Redmond mafia twists their arm from time to time…” We’ll show more about that later in the series. The Intel insider said, “as far as compilers and support for FGPAs are concerned I have Quartus installed and could use it for creating circuits, but maybe there are some other components that are still Windows-only…” █ ䷩ 𝚕𝚒𝚗𝚎 333 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 01.06.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ ✐ Links_6/1/2021:_Linux_Mint_20.1_“Ulyssa”_Released,_Violent_Insurrection_in the_United_States⠀✐ Posted in News_Roundup at 4:22 pm by Dr. Roy Schestowitz 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇insurrection-us⦈_ 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * GNU/Linux o Distributions o Devices/Embedded * Free_Software/Open_Source * Leftovers * § GNU/Linux⠀➾ o ⚓ Dell_expands_its_Optiplex_Ultra_line_of_PC-in-a-monitor-stand computers⠀⇛ Both the OptiPlex 7090 Ultra and OptiPlex 3090 Ultra are available with up to 64GB of DDR4-3200 memory, M. 2230 PCIe NVMe SSD and/or 2.5 inch hard drives, and support for Windows 10 or Ubuntu Linux. o ⚓ New_Dell_Optiplex_7090_Ultra_PC_hidden_in_monitor_stand⠀⇛ Both the Dell OptiPlex 7090 Ultra and OptiPlex 3090 Ultra are available with up to 64GB of DDR4-3200 memory and feature M. 2230 PCIe NVMe SSD and/or 2.5 inch hard drives, as well as offering support for either Windows 10 or Ubuntu Linux operating systems depending on your preference. o ⚓ From_Unix_to_Linux:_Key_Trends_in_the_Evolution_of_Operating Systems_(Part_3)⠀⇛ The previous article in this series examining the roots of Linux and Unix was something of an apotheosis to the BSD operating system. BSD remains significant in computer history, and important installations of BSD can still be found. Marshall Kirk McKusick, when commenting on the article, said that today, FreeBSD can be found in the Sony Playstation, Netflix servers, Juniper routers, and elsewhere. Indeed, BSD is important enough for the Linux Professional Institute to offer certification as a BSD Specialist. But somehow BSD got passed by in the 1980s as Unix became the most important operating system in the world. The attention went to other variants, even though some—such as SunOS, the flagship software of Sun Microsystems—were based on BSD. [...] Bauer also attributes the burgeoning of GNU/Linux to two distinguishing traits: the strength of its distributions and the license under which it was developed. Regarding distributions, he says: “From very early on users could choose between militantly free distributions like Slackware and Debian, commercial distributions with structured training and support programs like Red Hat and SuSE, and all points between. But this diversity hasn’t (yet) led to any disruptive schisms in Linux kernel development. Early in Linux’s evolution, this combination of commercial support contracts and kernel-development stability helped make Linux a viable choice for hosting network services for large corporations.” Bauer’s other point concerns the GNU General Public License (GPL), which requires anyone distributing the software to donate back any changes they make. BSD’s license falls into the permissive camp, which allows users to build on the software without opening up their changes. Although it makes sense that the more restrictive license would increase contributions, I am not persuaded that it makes a big difference. Companies that use free software have many incentives to get their changes back into the “core” regardless of legal constraints. Several reviewers of this article report that the GPL’s legal pressure increases the efforts made by companies to contribute back their code. McKusick claims, however, that FreeBSD has more committers than Linux, making the process for accepting commits easier to navigate. [...] In this article, we saw the failure of two important attempts to unify and drive forward Unix. BSD and the OSF both withered even as Unix became critical to computing. Perhaps part of their problem was that both BSD and the OSF depended on fairly traditional development processes. Version control was primitive (CVS came into use only during the late 1980s) and testing was seen as a task for a separate QA team. The management of people and personalities was even less understood. Under such conditions, an orderly and convivial development model for Unix seemed impossible. But the Internet was growing and with it new opportunities for collaborative production. The final article in this series starts with that elusive promise. Programmers were exploring new models for distributed development in the early 1990s, including a 19-year-old computer science student named Linus Torvalds. o § Kernel Space⠀➾ # ⚓ Google_Continues_Work_On_Linux_“Restricted_DMA”_For Situations_Like_Remote_WiFi_Attacks_–_Phoronix⠀⇛ Google engineers continue working on the Linux kernel around “Restricted DMA” for helping to protect systems that lack DMA access control for hardware without an IOMMU. Protected DMA aims to help prevent data leakage or corruption stemming from DMA access to system memory unexpectedly for systems without an IOMMU. One of the lead motivators for this work is due to PCI Express giving full system memory access and there already being proven vulnerabilities like WiFi firmware exploits that could escalate to a full system exploit even remotely via WiFi. Google’s Project Zero illustrated such WiFi attacks in 2017. # ⚓ Bootlin_welcomes_Thomas_Perrot_in_its_team_–_Bootlin’s blog⠀⇛ Since December 1st, 2020, we’re happy to have in our team an additional engineer, Thomas Perrot, who joined our office in Toulouse, France. # ⚓ Various_helpful_feedback⠀⇛ I will still attempt to get the 5.10.x kernel to be “AMD friendly”, for those who want to run EasyOS on modern AMD hardware. # § Graphics Stack⠀➾ # ⚓ Raspberry_Pi_“VC4″_DRM_Driver_Sees_10/12_BPC_Color Depth_With_Linux_5.12_–_Phoronix⠀⇛ With Linux 5.12 the Broadcom BCM2711 SoC used by the Raspberry Pi 4 will see 10 and 12-bit color support with the VC4 Direct Rendering Manager driver. Currently the open-source VC4 DRM driver that is used by the Raspberry Pi 4 and newer has just been exposing 8-bit color support while 10/12-bit support is pending for Linux 5.12 for those with capable displays. # ⚓ HDMI_Forum_Closing_Public_Specification_Access_Is Hurting_Open-Source_GPU_Drivers⠀⇛ It’s been recently elaborated why the likes of FreeSync support over HDMI aren’t coming to the open-source drivers, at least not yet… It stems from the decision by the HDMI Forum to prevent public access to the HDMI specification, which in turn is hurting open- source graphics drivers. With the HDMI specification no longer being public but only to “HDMI Adopters” is complicating the open-source GPU driver support. Even for those that are part of the HDMI Forum like AMD in turn cannot provide an open-source implementation of features covered by the closed spec for in turn potentially and indirectly opening up aspects of it to the public. o § Applications⠀➾ # ⚓ theBeat_–_audio_player⠀⇛ Linux offers a huge array of open source music players. And many of them are high quality. I’ve reviewed the vast majority for LinuxLinks, but I’m endeavoring to explore every free music player in case there’s an undiscovered gem. theBeat is an audio player that’s based on Phonon, the multimedia API provided by KDE and is the standard abstraction for handling multimedia streams within KDE software. theBeat is free and open source software built using Qt. # ⚓ gdu_Is_A_Fast_Console_Disk_Usage_Analyzer_(Alternative_To ncdu,_du,_Etc.)⠀⇛ du is a new console disk usage analyzer developed with speed in mind. It’s written in Go, and available for Linux, macOS and Microsoft Windows. gdu (Go Disk Usage) is very similar to ncdu, a popular console disk usage analyzer, with one major difference: speed. gdu makes use of parallel processing, being especially created for solid state drives (SSD). It also works with hard disk drives (HDD), but its performance gain compared to other tools is not so great in this case. o § Instructionals/Technical⠀➾ # ⚓ Using_the_Find_Command_in_Linux⠀⇛ There’s a very powerful Linux command that can save you lots of headaches when used in the right places. It’s called find. It walks through the file tree, starting from the provided path. Next, it prints each directory and file, including its path relative to the current working directory. Let’s explore the find command in Linux together! # ⚓ NixOS_Development_Environments⠀⇛ When developing and running software, and many times, you need a very particular set of libraries in your environment. You achieve this with virtual environments, containers, and other tricks. However, you do not necessarily need all that. One common case is when you program in Python, you must choose between the two big versions. This has caused many headaches for users and developers alike. You can avoid all this if your libraries are designated, especially for one run. This may sound impossible or unnecessary, but it is very convenient for rare use cases and development. [...] Using NixOS requires a bit more effort than other distributions. Having said that, if you want to develop software, the effort is worth it. You will keep your main system cleaner and can hop between projects without creating troublesome conflicts between environments. # ⚓ Getting_started_with_GIT_on_Linux⠀⇛ Git is a distributed version control system. It is used for tracking changes in any files. It was designed for coordinating work among programmers operating on source code during the software development process. In this article, I will show you the commands to perform basic operations on a Git repository. We will use the Ubuntu server as an OS. The same commands can work on any of the operating systems and just the installation part will be different. # ⚓ How_to_Check_A_Software_Package_Details_in_Ubuntu_Linux_| UbuntuHandbook⠀⇛ Looking for detailed information about a software package, e.g., maintainer, dependencies, sources, installed size, etc? There are a few tools to tell the information of software packages in classic .deb format in Ubuntu Linux. And here I’m going to show you one by one. # ⚓ How_to_Configure_FTP_with_TLS_in_Ubuntu_–_Linux_Hint⠀⇛ FTP (File Transfer Protocol) is primarily used to transfer files between computers. FTP works in client-server architecture, in which the client asks for a file from the server and the server returns the required file to the client. On the client machine, the FTP client application is used to communicate with the server. It is also possible to access the FTP server on the browser. By default, FTP communicates over an insecure channel, but it is possible to configure FTP to transfer data over a secure channel. In this tutorial, you will learn how to configure an FTP server with TLS and then use FileZilla as a client application to connect with the FTP Server. # ⚓ How_to_Configure_SPICE_Server_in_Debian_10⠀⇛ The Simple Protocol for Independent Computing Environments or SPICE is a protocol used to access and control remote desktops of virtual machines. It is based on client-server model, where a server (SPICE server) is installed on the host machine and runs a guest VM to be accessed over the Internet. The guest VM is remotely controlled by an client system running a Spice client. QEMU, a open source machine emulator and virtualizer, uses SPICE server to provide remote desktop capabilities. QEMU executes the guest code directly on the host CPU. This improves performance QEMU itself uses KVM (Kernel-based Virtual Machine), a linux kernel module, to perform hardware virtualization. # ⚓ How_to_Install_Vagrant_Virtual_Machine_Manager_on_Ubuntu 20.04_LTS⠀⇛ Vagrant is a command-line tool used by developers to manage different virtual machines. To use Vagrant in their system, users need to have either VirtualBox, or Hyper-V, or Docker installed in their systems. The plugin system of Vagrant also provides VMware support. Vagrant is used by developers on large scale to set-up their development environment and make use of it all across the various operating systems. Vagrant can be installed on various Linux platforms, here we will use Ubuntu as the basis. In this tutorial, we will walk users through the installation of Vagrant on an Ubuntu 20.04 system. We will be using VirtualBox as the virtualization backend. # ⚓ How_to_Ping_Ports_on_a_Remote_Host_–_buildVirtual⠀⇛ This article is all about the different methods you can use to ping ports to help in troubleshooting network connectivity issues. The ping command is available across just about every device you can log in to, making it the go to tool to use to verify network connectivity to a remote host. # ⚓ How_to_Upload_a_File_using_PHP_&_Ajax_–_Anto_Online⠀⇛ This post will show you how to upload a file using PHP & Ajax. File handling can sometimes require quite unique solutions. The conventional way of file upload is using a
