The Best 21 Open-source Headless CMS for 2020

Filed under
Server
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.

  • Communication by example: Which methods do high-performing open source communities use?

    Although effective communication is an essential life skill, it is the most critical element in any business [2]. Lack of accurate communication is the common cause of any organization’s issues, causing conflicts, reducing client relationships, team effectiveness, and profitability [2]. According to the Project Management Institute (PMI), ineffective communication is the main contributor to project failure one-third of the time. It has a negative impact on project success more than half of the time [1].

    In open source projects where there is a diverse and world spread community, effective communication is the key to projects’ success. Using the right technology is crucial for that. So, which tools do open source communities use for communication?

On Safety Razors and Technology

Filed under
Server
OSS

Think Windows on one side, vs Linux (and the BSDs) on the other (with macOS initially being in the middle and increasingly swaying to becoming even more constraining than Windows). Think proprietary gaming consoles and mobile IAP-chasing games, vs game platforms that encourage participation like TIC-80 and LÖVE. Think US-centric proprietary social networks (Facebook, Twitter) and services (Dropbox, Google Suite) vs distributed social networks (Mastodon, Pleroma, Diaspora etc.) and self-hosted services (Nextcloud, Cryptpad etc.).

What are most people sacrificing to the altar of promised convenience? Literally both time and money: our attention, higher costs; also our autonomy (you’re locked in) and our privacy (… so platform owners can mine your attention and monetize what they observe of your behavior).

If you believe in capitalism, this is bad news. If you don’t it’s even worse.

[...]

But in other jurisdictions like the US, regulation might be a long time coming, except maybe in California (plus the companies we’re trying to unshackle users from are mostly US-based). So a lot of the solution has to be bottom up.

We simply need to lower barriers to entry, both actual and perceived, to using the platforms we’re championing. Some involve compromises (e.g. Flatpak is a great way to abstract away the differences between Linux distributions, to the point that it’s easier to install proprietary apps, including Steam – which improves the availability of games on Linux despite, yes, being proprietary). Some involve corporate backing (e.g. Fedora on Lenovo laptops). A lot would involve being more welcoming to newcomers, and bridging the actual usability gaps there are.

It’s hard enough to overcome incumbency and the network effect. Let’s not make it harder for ourselves.

  • Advantages of Using Linux Virtual Machine or Linux Server Hosting

    With Linux, you do not need to worry about security, and you can download software from the Internet. Many online sites offer you Linux hosting and Linux server hosting. However, you have to check for the reliability and quality of the website. It should be an established website with many years of experience.

    You can check the Linux hosting and Linux server hosting providers and determine which one will suit your requirements. They should have enough information on their website so that you can get all the relevant details. The website should also explain the technicalities well. The website should provide details about the services offered and the cost that you will have to pay.

4 Best Free and Open Source Linux FTP Servers

Filed under
Server
Software

File Transfer Protocol (FTP) is a time-honored method of transferring files to and from a remote network site. FTP is built on a client-server architecture and uses separate control and data connections between the client and server applications. The FTP client connects to the FTP server, and enables the user to send and retrieves files from that server.

FTP is one of many different file transfer protocols that are used. Other examples include the Hypertext Transfer Protocol (HTTP), BitTorrent, the SSH File Transfer Protocol (SFTP), and Secure Copy (SCP).

In recent years, FTP’s popularity for general downloading files has declined. Linux distributions and software are now often downloaded by using direct downloads using a web browser, by BitTorrent, metalink, or by using a download utility. FTP is often tucked away as a download option even if it is available. While FTP can cause bandwidth problems it nevertheless remains a great way of moving large files.

The downside to using FTP is that it doesn’t necessarily take internet security risks into account. SFTP, the more advanced version of the same technology, enables you to manage files on your server just like FTP does. However, it uses a previously-established Secure Shell (SSH) connection to maintain the safety of your files and the site as a whole.

An FTP server is a software application which enables the transfer of files from one computer to another. Here’s our recommendations.

How Many Users Can Open Source Zoom Alternatives Handle?

Filed under
Server
OSS
Web

Zoom has been a boom since Coronavirus started, it seemed to be one of the very few software in the world capable of handling the planet’s digital transfer of most face-to-face communication since people were forced to stay in their homes during the quarantine. Governments, schools, universities, hospitals, companies, enterprises… All of them went to Zoom in order to face the new communication hassle.

Its stock market increased by %500 since the beginning of the pandemic, and tens of of millions of new users worldwide signed up for its premium plans. Everything sounded so great so far for Zoom, unlike most of the human race standing on the other side of the equation.

Until, an investigational report by the FTC showed that Zoom lied about its end-to-end encryption for years, and that its so-called E2E secure communication is actually false marketing. Of course, users and developers around the world had no way of verifying Zoom’s marketing claims easily since it was a proprietary, closed-source application. And thus, they were not able to check the source code by their selves to verify those claims.

Zoom being fully proprietary is why people started switching into open source zoom alternatives, like Jitsi, BigBlueButton and many others, so that they don’t remain in Zoom’s jail locking all their remote communications in one place.

10 years and 10 million cores: charting OpenStack’s greatest achievements

Filed under
Server
Ubuntu

At the heart of OpenStack, as with many open source projects, is a thriving community. Jonathan Bryce, Executive Director at the newly renamed Open Infrastructure Foundation which sits behind OpenStack, feels this is it’s finest work. “OpenStack’s greatest achievement is our community – a growing group of diverse contributors, users, and vendors who have enabled OpenStack to be one of the top three most active open source projects, in addition to Linux and Chromium.”

And while not always seen as being ‘mainstream tech’, the numbers are staggering. Bryce continued: “Over 100,000 individuals from 187 countries continue to support a project that is running over 10 million cores in production, powering critical infrastructure like banks, telecoms, railroads, retailers, hospitals, and more. I am so proud of the work that our community puts in daily to keep the world running on OpenStack.”

One of the biggest issues any technology can experience is scalability. Growing fast enough to suit demand, but also ensuring that the tech can deliver consistent quality as it does so. But these views of community – and its growth – are echoed by Georgi Georgiev, CIO of Japan’s SBI Bits: “Finding the appropriate technologies to build a virtual environment is a challenge of its own. OpenStack solved this problem by putting together a great stack of projects, and more impressively, built a community around it to support. This is the best that could have happened for open source, with OpenStack being available freely to everyone, while also enabling companies to package it up and sell while improving the product together.”

Talking of growing fast, OpenStack’s complimentary nature as a companion to the ever scalable public cloud provides organisations with the best of both worlds according to Tytus Kurek, Product Manager, at Canonical: “Although public clouds have almost dominated the cloud computing market, OpenStack adoption continues to grow every year. This is because OpenStack continues to deliver a cost-effective extension to the public cloud infrastructure, allowing organisations to take control over their budget. As one of the biggest contributors to the OpenStack project, Canonical is looking forward to seeing what the next 10 years will bring.”

  • Terraform vs Ansible: What's the Difference?

    The way DevOps as a culture is gaining momentum, tools like Ansible and Terraform witnessing a huge demand and popularity.

    Both tools are considered as Infrastructure as Code (IaC) solutions which helps in deploying code and infrastructure. While Ansible acts as a configuration management solution commonly abbreviated as “CM”, Terraform is a service orchestration or provisioning tool.

    Note that there are overlaps and these terms are not necessarily mutually exclusive. This is what confuses people and this is why I am going to compare Ansible and Terraform.

    I'll explain what are these tools used for, what are their pros and cons. This will help you decide whether you should use Ansible or Terraform in your projects.

  • Sysadmin tales: Take a look back at an old school IT prank | Enable Sysadmin

    Set your Wayback Machine to the early ’80s. Disco was dead and gone, pop rock was making waves, and consumer computers were available enough that some schools started figuring out that teaching computers was something they should do.

    My school was one of those—the lovely Manheim Township High School in Neffsville, PA. A classroom was repurposed as a computer lab, as the prior computer area was barely larger than a closet and only had four terminals connected to some type of "miniframe" computer, with one Apple II computer on a rolling cart.

    [...]

    Now, the cable to connect the computer to the monitor was pre-VGA; it was just a simple RCA connector, as everything was monochrome. No screws to help hold the connector on tight. My friend and I (I don’t recall who had the idea, but I’d like to think it was me) decided to cross-wire all the monitors, so the monitor for one seat was connected to the computer at another seat. We did it side-by-side where we had to, but the ones on the island were really fun as we could connect them so the computer on one side of the table would drive the monitor on the other side of the table.

  • Create your first Knative app | Opensource.com

    Knative is an open source community project that adds components to Kubernetes for deploying, running, and managing serverless, cloud-native applications. It enables more productive development with less interaction with Kubernetes' infrastructure.

    Systemd 247 is out today as the latest major version of this Linux init system. Like most systemd releases, systemd 247 is very heavy on new features.  Systemd 247 most notably introduces the still-experimental systemd-oomd as the out-of-memory daemon with that Linux OOMD code originally developed by Facebook and later adopted for desktop use-cases. Once stabilized, the goal of systemd-oomd is for improving the behavior when the Linux system is low on memory / under memory pressure.  Beyond systemd-oomd, systemd 247 now defaults to using Btrfs with systemd-homed and other enhancements as outlined below.
