3 commands to reboot Linux (plus 4 more ways to do it safely)

Monday 29th of July 2019 10:35:42 PM
Linux is fully capable of running not weeks, but years, without a reboot. In some industries, that’s exactly what Linux does, thanks to advances like kpatch and kgraph.For laptop and desktop users, though, that metric is a little extreme. While it may not be a day-to-day reality, it’s at least a weekly reality that sometimes you have a good reason to reboot your machine. And for a system that doesn’t need rebooting often, Linux offers plenty of choices for when it’s time to start over.read more

Do you prefer a live demo to be perfect or broken?

Monday 29th of July 2019 05:38:22 PM
At DevFest DC in June, Sara Robinson, developer advocate at Google Cloud, gave the most seamless live demo I've ever witnessed.Sara live-coded a machine model from scratch using TensorFlow and Keras. Then she trained the model live, deployed it to Google's Cloud AI platform, and used the deployed model to make predictions.With the exception of perhaps one small hiccup, the whole thing went smoothly, and I learned a lot as an audience member.read more

nuclear – desktop music player focused on free streaming

Linux has an abundance of mouthwatering array of excellent open source music players. But I’m always on the look out for fresh and newfangled music players. nuclear lets you stream music over the internet. It offers easy access to YouTube, SoundCloud, and Jamendo (the latter with partial support), and there’s a plugin system to add additional services. It therefore seeks to offer a unified music environment for managing music content. nuclear is an Electron based application written in the JavaScript programming language. It features hardware acceleration (using your GPU). Read more

  • With Open-Source Caravan Wallet, Unchained Wants to Make Multisig Mainstream

    Revealed exclusively to Bitcoin Magazine in anticipation of the launch, Caravan is the latest tool in Unchained Capital’s suite of bitcoin investor products. Like the Collaborative Custody that came before it, Caravan is a multisignature bitcoin wallet, meaning it requires multiple devices/parties to sign off on a transaction before it is sent.

  • Texas A&M and Simon Fraser Universities Open-Source RL Toolkit for Card Games

    In July the poker-playing bot Pluribus beat top professionals in a six-player no-limit Texas Hold’Em poker game. Pluribus taught itself from scratch using a form of reinforcement learning (RL) to become the first AI program to defeat elite humans in a poker game with more than two players. Compared to perfect information games such as Chess or Go, poker presents a number of unique challenges with its concealed cards, bluffing and other human strategies. Now a team of researchers from Texas A&M University and Canada’s Simon Fraser University have open-sourced a toolkit called “RLCard” for applying RL research to card games.

  • MemVerge Introduces Open Source Solution to Improve Spark Shuffle Processes

    MemVerge, the inventor of Memory-Converged Infrastructure (MCI), today announced MemVerge Splash, a first-of-its-kind, highly performant open source solution that allows shuffle data to be stored in an external storage system. MemVerge Splash is designed for Apache Spark software users looking to improve the performance, flexibility and resiliency of shuffle manager. Traditionally, when shuffle data is stored remotely, system performance can degrade due to network and storage bottlenecks which can negatively impact performance and stability. MemVerge Splash, working together with MemVerge's distributed system software named Distributed Memory Objects (DMO), solves these issues to make Spark highly performant through a high performance in-memory storage and networking stack.

  • The Non-Contradiction of Proprietary Finance and Community Open Source Programming

    I work in financial services, typically quantitative technology applications. A recent employer of mine was an imagery company, providing satellite and drone-sourced data into finance and insurance. In this heady mix of finance and space, I worked with people from defence, aerospace, geospatial, surveying and satellite communications backgrounds who were intrigued and often surprised to hear about the relevance of open source and community programming in financial services. [...] Facebook, Google, Amazon, Apple and Microsoft are certainly driving open source, often with ulterior motives, consciously supporting the sale of proprietary tools and services. Unconsciously, they can be accused of driving liberal west coast values and weeding out smaller commercial competition - I will be fascinated to see the consequences of Google releasing its Quantitative Finance Tensorflow. I also acknowledge the historical and continuing proprietary tendencies of financial services. A finance technology VP once told me around Year 2000 that “open source would never take off in quantitative finance”. While factually wrong even then, his assumptions were reasonable – management reputation, internal risk management and regulators beyond wouldn’t want untraceable, dangerous code running key algorithms. Key algorithms and the packages and languages in which they were embedded were also differentiators, hence proprietary. At the time, institutions did what they could to make the most, hire the best and beat the rest, and proprietary languages and code were the norm.

  • Appear.in Vs. Jitsi: Subscription WebRTC Faces Off Against Open-Source VC

    Open-source video conferencing is one of the few remaining glimpses of the utopian potential of the internet. If you’re willing to get a little sentimental about what the internet is or was supposed to deliver, you can see it within the chat windows of apps such as Jitsi–emerging technologies developed and given away for free so that anyone and everyone can participate in the digital communications revolution. That’s the idealized version of Jitsi’s existence, anyway. The reality is that while the highly adaptable, open-source app is still free to use and deploy within personalized platforms, it has become something of a research and development unit for subscription content providers. So, Jitsi stands as a kind of glorified public Beta test of the latest video conferencing technology. Its logical counterpoint in many ways is Appear.in (recently rechristened Whereby). This WebRTC-powered video platform has taken the same open-access ideals of Jitsi and turned them into a commercial subscription service.

  • Ether1.org, Open Source Blockchain Project, Rolls-Out ethoFS - A Decentralized Website Hosting & File Sharing Protocol That Aims to Combat Web Censorship

    In an industry first move, Ether-1 (ether1.org) has completed a network wide deployment of their decentralized, immutable data hosting protocol called ethoFS. With their unique democratized and "decentralize everything" approach, this latest technological advancement furthers the ideals originally taken mainstream by people like Julian Assange and Edward Snowden. EthoFS (ethofs.com) combines blockchain technology and IPFS creating a simple to use hosting platform that allows anyone to store data across a network of nodes with several levels of redundancy and immutability built into the decentralized system. The ethoFS system prevents a multitude of attack vectors and censorship efforts to allow any data or website to be hosted beyond the reach of "big brother."

  • Winter is coming even more quickly

    Motivated by my work at the DFINITY Foundation, I was looking into interpreters for WebAssembly written in Haskell, and found my colleagues John Wiegley’s winter: A straight-forward port of the WebAssembly reference interpreter, written in Ocaml by Andreas Rossberg (another colleague of mine … I guess there is a common theme here.) Obviously, an interpreter will never be as fast as a real compiler implementation (such as the one in v8, lucet or wasmtime). But for my purposes an interpreter is fine. Nevertheless, I don’t want it to be needlessly slow, and when I picked up wasm, it was clear that I had to work at least a little bit on performance.

Cheat sheet for Linux users and permissions

The Linux operating system is a true multi-user OS, meaning it assumes that there's data on every computer that should be protected, whether in the interest of privacy, security, or system integrity. Linux uses file ownership and permissions to manage file and folder access. For administrators who deal with different user environments all day, this system is easy to understand, calculate, and control. Read more
