  • Eric Voorhees compares trust in politicians to open source code

    Early Bitcoin advocate Eric Voorhees has said that “by holding Bitcoin, you are ultimately trusting open source code” in a dig at political systems all around the world.

    Political trust levels are currently plummeting. In countries like Venezuela, we can see political turmoil spilling into the lives of citizens who are now fleeing in droves across the borders. Also highly ranked on the list of politically unstable countries are Brazil, Ukraine, and Turkey, who have all seen major surprises in their recent elections.

  • Open source DEX protocol Loopring adds cryptography to technology mix

    Brecht Devos, protocol development lead, Loopring, said, “A number of hurdles have delayed the adoption of DEXs to date, including, but not limited to, a lack of scalability. However, there’s no doubting that decentralized exchanges represent the future of crypto trading, addressing, as they do, the multitudinous issues faced by users of centralized exchanges in their day-to-day transactions, such as the risk of hacks, personal data leaks, or blocked funds.

  • Ethereum Core Developers Debate Benefits of More Frequent Hard Forks

    A group of ethereum’s veteran open-source developers discussed the subject in a bi-weekly meeting Friday, wherein they aired the possibility that system-wide upgrades, also called hard forks, to the software could be enacted as often as every three months.

    Wanting to “check the temperature,” the developer asking the question explained that certain upcoming ethereum improvement proposals (EIPs) such as state rents would require multiple upgrades sequentially spaced out for full effect.

  • Digital Asset open sources ISDA derivatives blockchain code

    In February the International Swaps and Derivatives Association (ISDA) released version two of its Common Domain Model (CDM) which aims to standardize the coding of derivatives trade events and processes. Today Digital Asset announced that it’s working with ISDA on an open source code library that implements the CDM in Digital Asset’s smart contracting language DAML.

    The aim of implementing the CDM across the derivatives sector is to save money, and the savings could be as much as $2.5 billion. Last year Ledger Insights spoke to Lee Braine from the Chief Technology Office at Barclays about ISDA’s new standard. “Across the post-trade derivatives industry, there is infrastructure deployed that is too complex for its current purpose. And the proposal is analogous to pressing a technology ‘reset button’ allowing you to go back and radically simplify the nature of that infrastructure.”

  • Blockchain Set to Revolutionize the Open Source Movement

    It is evident that open source has transformed the current world. Developers rely extensively on open source software since it dominates the developer infrastructure. From the many operating systems like Linux in the cloud to databases like MongoDB, MySQL, and Redis, open source is there. Also, the movement dominates the programming languages themselves like Python, C, Javascript, PHP, and Java.

    Open source is also good for the consumers featuring in their phones, Android, to their method of web access like Firefox and Chrome. Hence, it makes technology more accessible and open which enables anyone to build anything.

  • Web 3.0 Accelerates As Leading Browser Expands Crypto Wallet Integration and Ethereum Blockchain Support

Opera’s Reborn 3 also includes a native cryptocurrency wallet for Windows, macOS and Linux, a follow-up to the crypto wallet integration on Opera’s Android app in December 2018.

  • IOTA To Replace Its Coordinator With An Open Source Version Of Coordinator On Mainnet

    The first open source ledger built to power the future of internet of things, IOTA is in a lot of use previously, right from waste management to green energy solutions. And now with the development of Coordicide, the platform may get a lot more transparent.

    Coordicide is actually the effort of removing the Coordinator from the IOTA networks and its research stage. For developing the Coordicide, IOTA is making the inner workings of the current network set-up fully transparent. IOTA aims to do this with an open-sourced version of the Coordinator running on Mainnet.

  • Altcoin News: IOTA to Replace Coordinator With Open Source Version

    IOTA’s technology has been put to a lot of use in the last few months, from waste management to green energy solutions. Now, it is about to become much more transparent with the development of the Coordicide.

    In an April 8, 2019 blog post, the firm gave some more insight into the development of Coordicide and the changes that will be made in that regard in the near future. First, it was explained what exactly the Coordicide is. According to the post, it is a deliberate effort to remove the Coordinator from the IOTA networks and is its research stage.

    [...]

    This open source version of the coordinator is called the Compass and was initially released some months back and allowed the opening of a private network, running of tests, and development PoCs. So far, the Compass has been tested on the spamnet and devnet and is now ready to be moved to the mainnet. IOTA has stated that using an open source version of the coordinator will make the network more transparent while improving it.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

Red Hat and SUSE Leftovers

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.

  • Demystifying Containers – Part II: Container Runtimes
    This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications. Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.

This follows our open / open policy of upstream first and community involvement.

NSA Back Doors in Windows Causing Chaos While Media is Obsessing Over DoS Linux Bug

  • U.S. Government Announces Critical Warning For Microsoft Windows Users
    The United States Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) has gone public with a warning to Microsoft Windows users regarding a critical security vulnerability. By issuing the "update now" warning, CISA has joined the likes of Microsoft itself and the National Security Agency (NSA) in warning Windows users of the danger from the BlueKeep vulnerability. This latest warning, and many would argue the one with most gravitas, comes hot on the heels of Yaniv Balmas, the global head of cyber research at security vendor Check Point, telling me in an interview for SC Magazine UK that "it's now a race against the clock by cyber criminals which makes this vulnerability a ticking cyber bomb." Balmas also predicted that it will only be "a matter of weeks" before attackers started exploiting BlueKeep. The CISA alert appears to confirm this, stating that it has, "coordinated with external stakeholders and determined that Windows 2000 is vulnerable to BlueKeep." That it can confirm a remote code execution on Windows 2000 might not sound too frightening, this is an old operating system after all, it would be unwise to classify this as an exercise in fear, uncertainty and doubt. Until now, the exploits that have been developed, at least those seen in operation, did nothing more than crash the computer. Achieving remote code execution brings the specter of the BlueKeep worm into view as it brings control of infected machines to the attacker.
