  • SeaMonkey 1.1.19 compiled in EasyOS

    As I seem to have settled on Firefox as the main browser in EasyOS, I still want to keep a WYSIWYG HTML editor in the build, builtin. So, my mind turned to considering old versions of SeaMonkey...
    Looking at my old notes, the 1.1 series look good. Very old, version 1.1.19 was the last, released, I think, in 2010. The 1.1 series was the last, I think, that can be configured to build a standalone composer.
    But, then, with SM you get the browser and composer editor, both, for not much increase in size. So why not build the suite. The browser could be a substitute for the 'surfer' HTML viewer that I am currently using to view local help files in Easy.

  • How to install Proxmox? - Unixcop the Unix / Linux the admins deams

    Hello, friends. In this post, you will learn how to install Proxmox on a completely clean server. For this, then I will use a virtual machine but the procedure is simple and the same as on a real physical server.

    What is Proxmox?

    Proxmox VE “Virtual Environment” is a powerful enterprise-level virtualization platform 100% free and unlimited in its use.

    Of course, it has a license that allows us to obtain additional features that facilitate the administration of it. But in general, we can use it in many of our projects for free.

    Proxmox is essentially a Debian that adds KVM virtualization and Container-based Virtualization. Therefore the whole base is Free and this makes it possible for the final product to be free. How is it supported? The proxmox business model is based on training, certifications, and support and as I mentioned an enterprise license.

    One of the main advantages of Proxmox is that it has a JavaScript web interface. This has an intuitive design where all KVM clients, Linux containers, storage units, and clusters are displayed.

    So, let’s go for it.

The board of the Free Software Foundation (FSF) announced today that associate members of the FSF will be able to nominate and evaluate candidates for the nonprofit's board of directors for the first time in the organization's 37-year history.

Under new procedures adopted by the FSF board on January 17 and summarized here, the organization will proactively engage associate members with a sufficient history of association with the FSF in the recruiting process by inviting them to suggest board nominees and then research collectively those nominees' suitability for a position on the board, including most importantly their record of commitment to free software ideals. The new community engagement process is a key result of a six-month consultant-led review designed to help make FSF governance and recruitment practices more transparent and participatory, while more systematically ensuring their commitment to the FSF's values and principles.

  • Linux Lock Screen Policy Enables Consistent Device Governance

    Every operating system should have security controls deployed, and Linux is no exception. Having a lock screen policy is even more of a consideration with a remote workforce where team members could be using a local coffee shop or other unsecured locations as an “office,” which increases the odds that bad actors could obtain physical access to devices. JumpCloud has created an easy-to-deploy policy to configure lock screen settings for Linux throughout your fleet, providing consistent governance and a scalable method for a secure OS configuration.

A note for LWN subscribers

January 22, 2022 will be the 24th anniversary of the publication of the first LWN.net Weekly Edition. A lot has happened in the intervening years; the Linux community has grown immeasurably, and LWN has grown with it. Later this year will also be the 20th anniversary of the adoption of our subscription-based model, which has sustained LWN ever since. There is a change coming for our subscribers that will, with luck, help to set up LWN to thrive in the next coming years. The nominal price for an LWN subscription is $7 per month, a price that has remained unchanged since 2010. That $7 buys a lot less now than it did twelve years ago. Your editor is reliably informed by the Internet that inflation in the US has been just under 28% from 2010 until the middle of 2021; that rate doesn't include the last few months. Prices for some things, most notably health insurance in the US, have increased by rather more than that. Read more
