Linux Blimp

In this article, we will show how to run commands on multiple Linux servers at the same time. We will explain how to use some of the widely known tools designed to execute repetitive series of commands on multiple servers simultaneously. This guide is useful for system administrators who usually have to check the health of multiple Linux servers everyday.

For the purpose of this article, we assume that you already have SSH setup to access all your servers and secondly, when accessing multiple servers simultaneously, it is appropriate to set up key-based password-less SSH on all of your Linux servers. This above all enhances server security and also enables ease of access.

1. PSSH – Parallel SSH

Parallel-SSH is an open source, fast and easy-to-use command line based Python toolkit for executing ssh in parallel on a number of Linux systems. It contains a number of tools for various purposes such as parallel-ssh, parallel-scp, parallel-rsync, parallel-slurp and parallel-nuke (read the man page of a particular tool for more information).

Public Q&A sessions Seeking Community Input to be Held at Node+JS Interactive in Vancouver, Canada, Oct. 10-12

SAN FRANCISCO, Oct. 4, 2018— The Node.js FoundationandJS Foundation today announced an intent to merge. A Q&A session will be held onsite at Node+JS Interactive from 7:30am – 8:30am PT, October 10 at West Ballroom A. Anyone attending Node+JS Interactiveis welcome to attend; questions can be submitted in advance anonymously via this Google Form or by email at pr@nodejs.org.

Leaders from the Node.js Foundation Board of Directors, Technical Steering Committee and Community Committee will join representatives from the JS Foundation Board of Directors and Technical Advisory Committee to facilitate the discussion, answer questions and solicit community input on the possible structure of a new Foundation. Joining forces will not change the technical independence or autonomy for Node.js or any of the 28 JS Foundation projects such as Appium, ESLint, or jQuery.

JavaScript is a versatile programming language that has expanded far beyond its role as a backbone of the web, entering new environments such as IoT, native apps, DevOps, and protocols. As the ecosystem continues to evolve —moving from browsers to servers, desktop applications to embedded devices —increased collaboration in the JavaScript ecosystem is more important than ever to sustain continued and healthy growth.

“The Node.js Foundation and JS Foundation boards have met several times already to discuss a potential alignment of the communities. The Foundation leaders and key technical stakeholders believe that a tighter alignment of communities will expand the scope of the current Foundations and enable greater support for Node.js and a broader range of JavaScript projects,” said Mike Dolan, Vice President of Strategic Programs, the Linux Foundation. “We are very interested in hearing directly from the community and welcome all questions, ideas, and opinions so that the structure aligns with the expectations of the community. For this reason, no formal decisions regarding a merged Foundation and its potential organizational structure, governance policies, technical framework or leadership have been made at this point and will be formalized based on feedback from the community.”

Additional goals for a merger include:

• Enhanced operational excellence;
• Streamlined member engagement;
• Increased collaboration across the JavaScript ecosystem and affiliated standards bodies;
• An “umbrella” project structure that brings stronger collaboration across all JavaScript projects; and
• A single, clear home available for any project in the JavaScript ecosystem.

Today, JavaScript is nearly ubiquitous. Enterprises have been able to greatly reduce training costs and increase developer productivity because frontend JS developers can work on the server side, and vice-versa, eliminating the context switches and enabling all developers to pull from the same knowledge base and vast module ecosystem. Node.js is a major catalyst for this growth. It has become an important part of the modern web development stack and is often the assumed default when working with JavaScript. Merging the Foundations will bring the governance of these technologies in line with its real-world use.

“JavaScript is at the core of an ecosystem of technologies that form the backbone of the web and play an increasingly vital role across industry and society,” said Dan Appelquist, Director of Web Advocacy & Open Source at Samsung Research UK and JSF Board Member. “Strong governance, encouraging inclusive contributor communities and engagement in the ongoing standards development are all important factors in ensuring this ecosystem continues healthy development. A merged foundation is well positioned to deliver on these goals.”

“The possibility of a combined Foundation and the synergistic enhancements this can bring to end users is exciting,” said Todd Moore, Node.js Board Chairperson and IBM VP Opentech. “Our ecosystem can only grow stronger and the Foundations ability to support the contributors to the many great projects involved improve as a result.”

Git is a version control system. Linus Torvalds created Git in 2005 for development of the Linux kernel. Git is mainly used for software source code management. However, it can be used to keep track of any set of files such as HTML or CSS or a tutorial written in the markup language. Git is a Distributed Version Control Systems. A dedicated Git server helps to manage access control, show contents of a Git repository via the web and manage multiple repositories. In a Git, clients do not just check out the latest snapshots of the files. They entirely mirror the repository including history.

Microsoft to acquire Github

It is official now. Microsoft announced an agreement to acquire GitHub, the world’s leading software development platform. I think it is a wake-up call for open source projects. So much of open source code hosted on Github. I twitted this other day:

I got an email from one my client who is @Github private repo business customer. They want to move out of Github to a personal GIT server hosted either in AWS or Google Cloud. They fear that Microsoft might get insight into their codebase. Small startups/business do not trust MS.

— nixCraft (@nixcraft) June 3, 2018

Some of us working in IT for a long time. We have not forgotten big evil Microsoft. Microsoft is the same company that was behind the SCO Lawsuit against Linux and called open source cancer. It actively follows a policy of Embrace, Extend, Extinguish. Microsoft is also known for its abuse of patents (see Netscape and Microsoft is generating $2 billion per year in revenue from Android patent royalties) and the recent Windows 10 Telemetry privacy issues. The list is endless. One should be a cautious trusting company that has a strong history of abuse towards open source communities and Linux operating system. Hence, installing your Git server is the best policy.

Various implementations of Git and Github alternatives

There is a number of implementations of Git server:

1. Proprietory (e.g. Bitbucket)

Like a year ago, and ago, and ago, Sparky needs YOUR help now!

As you probably know, SparkyLinux is a non-profit project so does not earn money.
And probably some of you know that we have to pay bills for hosting server (vps), domains, the power (electricity), broadband (internet connection), etc., etc., from our personal, home budget.

The time for paying for our server coming quickly again so help us sending donation now!

This year we need 1200 PLN for the VPS which has to be paid until November 9, 2018.

And as every month, we also need 500 PLN for other bills to cover most our needs.

So all together, this month, we need your donations for about 1700 PLN / ~400 Euros / ~460 USD), please.

We also have asked for donations our community at Linuxiarze.pl and ArchiveOS.org as well. Our virtual server hosts a few web pages, all IT / Open Source / Linux related: SparkyLinux.org, Linuxiarze.pl, ArchiveOS.org and SoftMania.org.

So please donate now to keep Sparky alive. Any donation will be very helpful.

You are the best community in the Universe so I really believe we CAN do it!

Visit the donation page to find how to send out money.

The live media of Sparky Rescue Edition is updated up to 5.5.1 which provides minor bugs fixing.

Changes:
– system updated from Debian testing repos as of October 05, 2018
– fixed menu entry of DDRescue-GUI and Gparted
– added new tools: vim, chntpw, sparky-aptus
– reconfigured sparky-remsu tool: changed name of sparky-xterm-exec to sparky-remsu-exec, so it had to be changed in obmenu-generator too. The old name could confuse users so the new one is much proper. The sparky-remsu-exec tool lets run non-sparky tools with root privileges.

The new iso images can be download from the download/rolling page.
