  • Hasura debuts open source event system to simplify serverless development

    Hasura, a company that creates tools for developers on top of the popular Postgres database, is introducing a new product in public Alpha today aimed at helping programmers build serverless apps more quickly and efficiently.

    The idea is to simplify function writing by offering an open source event system on top of Postgres to trigger events when certain conditions are met in the underlying database. This should help reduce the amount of coding needed to make something work, while also driving a more scalable system.

    Typically, programmers string together a series of API calls to services to take care of different parts of an app such as calling a payment or communications gateway. This saves the programmer from having to create the various pieces from scratch. The problem is that if anything goes wrong in the middle of a string of calls, the system can break down and typically has to start over.

  • Storj Labs Offers Unique Model for Cloud Storage

    Storj Labs launched an open source partner program that will divert revenues from its unique decentralized cloud storage platform to companies and individuals willing to house data on their computing systems.

  • Gitpod git-bolts git-IDE onto GitHub for in-browser code git-editing

    Developers who use GitHub – 28 million at last count – now have the option to edit code with the click of a button using Gitpod, an integrated development environment (IDE) that can be launched directly from the social code hosting site.

    Based on Theia, an open source cloud-and-desktop IDE developed by Ericsson, IBM, TypeFox and RedHat, Gitpod can be invoked by prefixing a GitHub URL with "https://gitpod.io#" or using a Chrome browser extension.

  • ACT’s Latest Act: Investing in an Open-Source Assessment Startup

    The company offers a suite of tools used to create, deliver and generate reports from digital assessments. Its main offering is TAO, an open-source platform that anyone can download for free to create and deliver tests. For a fee, the company will also offer custom content development services, cloud-based hosting and delivery and support and maintenance.

    [...]

    In the past three years, ACT has also acquired OpenEd, Pacific Metrics Corporation, ProExam and the National Research Center for College and University Admissions.

    The breadth of these investments, Roorda says, is a sign that ACT should no longer be viewed as just a college-admissions test (or, specifically, the SAT alternative). The nonprofit’s bets across a range of digital technologies, from adaptive learning to formative assessments, means that it is also closely watching other markets and companies including Knewton and Renaissance Learning.

    Roorda and Oswald both say open-source technologies will play an integral role in the future of education. “A closed market doesn’t grow,” says Oswald. “You need open standards for everyone to benefit.”

  • The New Rocket Science

    Open-source farming could challenge Big Ag and take crop production to a new heights.

    [...]

    Harper’s big idea, a project he called the Open Agriculture Initiative, was to unleash the innovative power of the internet on agriculture by means of wetware — tech that merges edible plants with silicon chips. Empowered with free, open-source software and food computer designs, he argued, we could all soon be experimenting with crops, sharing our discoveries, and fixing environmental problems. Imagine reducing our dependence on centralized Big Agriculture and growing more food more sustainably by bringing the farm into the home — or at least into the city limits — and building a distributed network of a billion nerd farmers.

Servers and Red Hat Leftovers

TuxMachines - Wed, 2018-09-05 21:07
  • Build a secure Docker host environment on Linux systems

    Run the latest stable OS release and patches on container hosts. Unlike VMs, containers share host OS resources and files, so a security issue could affect the entire Docker estate. OS management isn't difficult for enterprise IT teams, but approach with caution -- review all documentation prior to committing an update for Docker hosting systems. Virtual snapshots are a useful tool for this process, providing a log of changes and a rollback target if needed.

    Application security is only as good as what's on the stack below it. Assess the security settings on the host in question. Anyone with administrator-level access to the OS can manipulate the containers in the default configuration. Administrators should use keys for remote login to increase the environment's security level. In addition, implement a firewall, and restrict access to only trusted networks. Keep the attack surface to a minimum.

  • How to feel connected on a distributed team

    In March 2016, I started a new role as a fully remote employee. I was joining a company that I highly respected to do something I loved, and I no longer had to get in a car every day. Not having to commute was a real sell, especially since it’s not uncommon to spend an hour each way to get to work in the DC area. Missing out on lunch with coworkers and free snacks in the office was worth the sacrifice. Plus, I had plenty of friends and family in the area, so I wouldn’t feel the impact of being alone for eight hours a day. I was convinced that I was going to live my dream life.

Linus Torvalds: Changes in hardware change Linux development

TuxMachines - Wed, 2018-09-05 20:46

In Linux Version 4.19, Linux’s developers had to deal with a hardware security bug, an issue that was particuarly frustrating becasue it was someone else’s bug. But Linux creator Linus Torvalds hopes that such incidents will be less common in the future.

In the Linux development process, there is a two-week merge window for new code, then developers spend six to seven weeks looking for bugs. Usually, this process is not a big deal, Torvalds says. Most often, by the middle of the second week, bug-fixing ensues.

Arch vs Black Arch

Reddit - Wed, 2018-09-05 20:45

As the title implies, I'm debating which version of Arch to install and learn. I do some gaming currently on my windows rig, but I believe most of my games can be run under steamplay and proton so I'm not too concerned with that. Black Arch as I'm aware does have pentesting tools with it, and would make sense to go with given my field of study in cybersecurity and comp sci.

Basically what I'm trying to ask is, is there any reason I should go with one or the other? Should I keep my games and documents separate from any pentesting distros?

Bug Hunting Inlined Code

TuxMachines - Wed, 2018-09-05 20:20

Changbin Du from Intel recently posted some code to increase the range of the function tracer by increasing the number of function calls that were actually compiled into the kernel. Not all function calls are ever actually compiled—some are "inlined", a C feature that allows the function code to be copied to the location that calls it, thus letting it run faster. The downside is that the compiled binary grows by the number of copies of that function it has to store.

But, not all inlined functions are specifically intended by the developers. The GNU C Compiler (GCC) also will use its own algorithms to decide to inline a wide array of functions. Whenever it does this in the Linux kernel, the function tracer has nothing to trace.

  • Kubernetes is the new operating environment (Part 1)

    This is the first in a series of articles that consider the role of Kubernetes and application servers. Do application servers need to exist? Where does the current situation leave developers trying to choose the right path forward for their applications?

    Why Kubernetes is the new application server

    By now you’ve likely read “Why Kubernetes is The New Application Server” and you might be wondering what that means for you. How does it impact Java EE or Jakarta EE and Eclipse MicroProfile? What about application servers or fat JARs? Is it the end as we’ve known it for nearly two decades?

    In reality, it doesn’t impact the worldview for most. It’s in line with the efforts of a majority of vendors around Docker and Kubernetes deployments over the last few years. In addition, there’s greater interest in service mesh infrastructures, such as Istio, and how they can further assist with managing Kubernetes deployments.

    All these factors are drivers for the current trends within development—pushing more concerns traditionally associated with development down into the lower layers of the entire stack, with concerns moving into infrastructure or the operating environment an application runs on.

    Throughout the series, we will see that there is no need for doom and gloom. Although the mechanisms might change, there’s still a place for application servers and fat JARs when developing applications.

  • Understanding the State of Container Networking

    Container networking is a fast moving space with lots of different pieces. In a session at the Open Source Summit, Frederick Kautz, principal software engineer at Red Hat outlined the state of container networking today and where it is headed in the future.

    Containers have become increasingly popular in recent years, particularly the use of Docker containers, but what exactly are containers?

    Kautz explained the containers make use of the Linux kernel's ability to allow for multiple isolated user space areas. The isolation features are enabled by two core elements cGroups and Namespaces. Control Groups (cGroups) limit and isolate the resource usage of process groups, while namespaces partition key kernel structures for process, hostname, users and network functions.

  • Libre Computer's Renegade Elite Offers USB-C With DP, PCI-E x4, 4GB LPDDR4, 6 Cores

    While yesterday we looked at the Renegade ROK-RK3328-CC Libre Computer Board, they already have the successor well in the works. The Renegade was interesting as for just dollars more than the Raspberry Pi it offers better performance, Gigabit Ethernet makes the networking potential a lot more than the slow Ethernet on the Pi, there is USB 3.0 connectivity, and its using DDR4 memory, among other technical advantages. But the new Renegade Elite even puts that to shame.

  • Eleventh annual LibrePlanet conference set for March 23-24, 2019

    LibrePlanet is an annual conference for free software users and anyone who cares about the intersection of technology and social justice. For a decade, LibrePlanet has brought together thousands of diverse voices and knowledge bases, including free software developers, policy experts, activists, hackers, students, and people who have just begun to learn about free software.

    LibrePlanet 2019 will feature sessions for all ages and experience levels, including newcomers. Sharon Woods, general counsel for the Defense Digital Service (US Department of Defense) said, “Last year was my first LibrePlanet... I walked away a complete believer in free software.” In just the last three years, over a thousand people from around the world have attended LibrePlanet, with many more participating online by watching the free software-powered livestream, joining the conversation on IRC, or viewing nearly 40 hours of archived video on the FSF's GNU MediaGoblin instance.

    LibrePlanet 2019's theme is "Trailblazing Free Software." In 1983, the free software movement was born with the announcement of the GNU Project. FSF founder Richard Stallman saw the dangers of proprietary code from the beginning: when code was kept secret from users, they would be controlled by the technology they used, instead of vice versa. In contrast, free software emphasized a community-oriented philosophy of sharing code freely, enabling people to understand how the programs they used worked, to build off of each other's code, to pay it forward by sharing their own code, and to create useful software that treated users fairly.

Need a lighter, faster gnome look-a-like.

Reddit - Wed, 2018-09-05 19:30

I am currently running Gnome3 on my older laptop, and I like it for the most part. My only real issue, and I admit I'm enough of a noob to be incapable of seeing many, is that it is starting to run a little sluggish on my 2012 Mac. I'm assuming this has something to do with the heaviness of Gnome.

Is there a way I can make Gnome faster, or would I be better off scrapping this DE and getting a new one?

I'm open to change, so don't refrain from offering more challenging options.

Essential LaTeX Tools – typeset beautifully (Updated 2018)

TuxMachines - Wed, 2018-09-05 19:27

LaTeX is a document preparation system and document markup language for high-quality typesetting. The system was originally developed by Leslie Lamport in the early 1980s. LaTeX is based on Donald E. Knuth’s TeX typesetting language. Lamport says that LaTeX “represents a balance between functionality and ease of use”.

LaTeX is often used for technical or scientific documentation, particularly because it generates well formatted papers with beautifully crafted formulae, but the system can be used for any form of publishing. It employs beautifully crafted typesetting algorithms. Academic journals will often accept submission in this format.

Using the LaTeX system leads the author to concentrate on the structure of the document rather than its appearance. The author therefore focuses on what he/she wants to say, instead of fretting over page borders, font attributes, or formatting. Moreover, the author will be guided in the organisation, structure, and flow within the document.
