  • Ethereum Ecosystem: Open Source Sustainability Talks Pick Up Steam

    This week, Gitcoin co-founder Kevin Owocki gave a presentation at CoinFund’s monthly Rabbithole Talks on open source sustainability efforts. Therein, he surveyed a series of development funding possibilities whose profiles have surged in the Ethereum community over the last month as builders have grappled with finding the best funding paths forward.

    It’s an increasingly pertinent topic. The vast majority of the projects in the cryptoeconomy are open-source ventures or directly rely on open-source software, and Ethereum’s nook is no exception.

  • Grin Cryptocurrency to Vote on Change to Hard Fork Roadmap

    The open-source developers behind the privacy-oriented cryptocurrency Grin are discussing potential changes to the project’s hard fork roadmap.

    Specifically, since plans to keep the competition for its mining reward issuance through a series of system-wide upgrades (more popularly known as “hard forks”) may not pan out quite as well as hoped, those developing the code for the project are looking to potentially adjust the upgrade schedule.

    Prominent Grin developer John Tromp, who invented the proof-of-work mining algorithm “Cuckoo Cycle,” suggested changes to what will go into the next hard fork currently set for mid-July during a bi-weekly Grin Governance meeting Tuesday. Now, developers are putting the matter to a vote in two weeks time.

  • Securitize, Others Join Hyperledger Blockchain Project

    As of March 28th 2019, Securitize— along with eight other organizations— has joined the Hyperledger blockchain consortium. Hyperledger recently announced that it would be including additional Special Interest Groups (SIGs) to develop solutions for domain-specific problems.

  • New Open-Source WebLN Standard Gains Momentum for Bitcoin Lightning Network Payments

    The process of sending bitcoin lightning payments is fairly straightforward, but the new bitcoin standard, WebLN, was created with the purpose of improving lightning payments in a simpler way. The standard is an open-source system, which is presently gaining some traction as it is used by two of the more popular lightning wallets – Lightning Joule and Bluewallet. It is also used by multiple apps, including Lightning Spin, reducing the steps that users have to go through for payment.

    Considering that lightning is an experimental technology with a lot of risks for sending real money, this transition is a major step. Many users agree that this open source payment network is going to be the future of these payments, even going against the advice of developer warnings. As they have worked to process their payments, the users have found various issues.

  • Cryptocurrency Dash to open-source software repositories

    Today, the Dash community announced the open-sourcing of the Dash Platform software repositories, including the Distributed API (DAPI) and Drive.

  • Dash Core is Releasing Part of Its Software Repositories in an Effort to Open Source the Network

    Dash Core, the group behind the Dash cryptocurrency project has revealed this week that it has been releasing repositories of the Dash Evolution source code to the public in an aim to make the project more open source.

    Thus far, the group has kept the development of the Dash blockchain private both for security and competitive reasons, however, this decision may have sparked a lot of criticism from the community as most blockchain projects are publicly available in coding platforms especially GitHub available for the public to scrutinize and hunt for bugs. Due to public pressure, the Dash Core Group made promises to release the source code when it is ready for open-sourcing, a promise it is aiming to achieve now.

  • A Bitcoin Lightning Web Standard, Inspired By Ethereum, Is Gaining Steam

    That’s because a new bitcoin standard for simplifying lightning payments, the open-source WebLN standard, is gaining traction, now being used by Lightning Joule and Bluewallet, two of the more popular lightning wallets, as well as apps like Lightning Spin, to slim down the number of steps a user needs to make a payment.

    This is an important step for lightning, an experimental technology that is still risky to send real money over. Developer warnings aren’t stopping eager users from trying out what they believe to be the future of bitcoin payments, and as they’ve toyed with payments, they’ve bumped into issues trying to send or receive value.

  • 'Thousands' of Decentralized Finance (DeFi) Projects Under Development: ConsenSys

    The contributors at ConsenSys, a Brooklyn, New York-based Ethereum-related development studio, have published a blog post in which they have revealed that decentralized finance (DeFi) has “grown into one of the most active sectors” of the blockchain industry in 2019.

    Included in the evolving set of core technologies that now make up the globally accessible DeFi platforms are stablecoins, decentralized crypto exchanges, or DEXs (and/or exchanges that do not hold users’ private keys), multi-currency wallets, and various payment gateways, ConsenSys’ blog post noted.

My First 24 Hours With Purism's Librem 15 v4 Laptop And PureOS

tuxmachines.org - Ned, 03/31/2019 - 15:22

Purism's 15-incher starts at $1499, so it needs to look and feel premium. In my opinion it accomplishes that with its anodized black aluminum chassis, although the color becomes a magnet for fingerprints -- one complaint I've never had with my XPS 13 9370. You'll also notice a pleasing lack of branding. No logo on the lid or display. No stickers under the keyboard. It's just a sleek black slab.

Opening up the laptop reveals a top-right power button, a full-size backlit keyboard (10-key included) and a touchpad that boasts a thin silver trim that really makes it pop. The keyboard is exponentially better than any recent MacBook as it's more tactile and has more travel, but falls just short of the newer XPS 13 or any modern ThinkPad.

The touchpad feels just slightly sluggish compared to XPS 13 or MacBook (but this can improved by tweaking acceleration), resulting in tracking that isn't quite as smooth as its competitors out of the box. It's no deal breaker and is quite comfortable to use; it's just not the best of the bunch.

Apache: Apark, ASF (Apache Software Foundation) and Apache Kafka vs. Apache Pulsar

tuxmachines.org - Ned, 03/31/2019 - 14:41
  • Apache Spark Turns 10: The Secret Sauce Behind One Of The World’s Most Popular Open Source Projects

    It was the changing nature of big data technology and architectural models, that wrote the story for Hadoop. The infrastructure architecture moved towards edge computing, IoT and cloud computing and especially containers where the market is seeing an increase in Kuberenetes workload. With analytical and machine learning workloads increasing, there was an increased need for a unified analytics platform. And that’s exactly how Spark outperformed Hadoop in metrics such as In memory processing vs disk, real-time streaming and batch streaming besides providing a layer for integrating machine learning as well.

    As Apache Spark turned 10 years old, let’s see the strong driver that led to Spark adoption and what keeps it going. Dubbed as the official “in-memory replacement for MapReduce”, the disk-based computational engine is at the heart of early Hadoop clusters. Why Spark took off was because it reflects the changing processing paradigm to a more memory intensive pipeline, so if your cluster has a decent memory and an API simpler than MapReduce, processing in Spark will be faster. The reason why Spark is faster is because most of the operations (including reads) decrease in processing time roughly linearly with the number of machines since it’s all distributed.

  • 20 milestones at the Apache Software Foundation

    Not at all a question of parts unknown, more a case of parts where some are better known than others.

    The Apache Software Foundation (ASF)’s Jim Jagielski and Sally Khudairi have detailed 20 major milestones that exist under the auspicious auspices of the ASF today.

    Without detailing every project (and the ASF holds stewardship over 350 community-led projects and initiatives) and repeating the entire story linked above… we’ll tour a handful in celebration of the fact that the ASF passed its 20th Anniversary on 26 March 2019.

    It would be tough not to mention Apache HTTP Server. This is most popular open source HTTP server on the planet — it provides a secure and extensible server that provides HTTP services observing the latest HTTP standards.

  • Pub/sub messaging: Apache Kafka vs. Apache Pulsar

    These days, massively scalable pub/sub messaging is virtually synonymous with Apache Kafka. Apache Kafka continues to be the rock-solid, open-source, go-to choice for distributed streaming applications, whether you’re adding something like Apache Storm or Apache Spark for processing or using the processing tools provided by Apache Kafka itself. But Kafka isn’t the only game in town.

    Developed by Yahoo and now an Apache Software Foundation project, Apache Pulsar is going for the crown of messaging that Apache Kafka has worn for many years. Apache Pulsar offers the potential of faster throughput and lower latency than Apache Kafka in many situations, along with a compatible API that allows developers to switch from Kafka to Pulsar with relative ease.

The low-cost hardware revolution

tuxmachines.org - Ned, 03/31/2019 - 11:07

The inventiveness of the maker generation is finding its way into industry with cost-effective hardware, open source platforms and fresh ideas.

The wave of low-cost hardware success is unstoppable. Anyone thinking of low-cost hardware has developer boards front of mind: Raspberry Pi, Arduino or Beagle Bone. Since its launch in 2012, the Raspberry Pi has an amazing success story. With over 17 million devices sold worldwide, Raspberry Pi is the most popular single-board computer of all time. This mini-PC is the initiator of the low-cost trend.

But the Raspberry Pi has now found itself in a competitive market place as more developer boards try to emulate its success. From new one-board controls to accessories and extensions, the market is constantly seeing innovation. Shields, hats, power supplies and sensors – now a whole hardware ecosystem is available with the minicomputers.

OpenMandriva Appears To Be Experimenting With Profile Guided Optimizations

tuxmachines.org - Ned, 03/31/2019 - 10:57

OpenMandriva has been toying with some performance optimizations in recent times like preferring the LLVM Clang compiler over GCC, spinning an AMD Zen "znver1" optimized version of the OS/packages, and apparently now exploring possible Profile Guided Optimizations.

Profile Guided Optimizations (PGO) basically involve feeding the feedback of profiling data back into the compiler so it can better optimize the generated code based upon actual usage behavior of the software under test. PGO can pay off big time depending upon the code-base and how well the profile data models real-world workflows of the said software in question.

How to build a mobile particulate matter sensor with a Raspberry Pi

tuxmachines.org - Ned, 03/31/2019 - 08:30

About a year ago, I wrote about measuring air quality using a Raspberry Pi and a cheap sensor. We've been using this project in our school and privately for a few years now. However, it has one disadvantage: It is not portable because it depends on a WLAN network or a wired network connection to work. You can't even access the sensor's measurements if the Raspberry Pi and the smartphone or computer are not on the same network.

To overcome this limitation, we added a small screen to the Raspberry Pi so we can read the values directly from the device. Here's how we set up and configured a screen for our mobile fine particulate matter sensor.

  • Surrounded by inspiration, Appalachian alumnus keeps applications running at IBM

    As a site reliability engineer at IBM, Appalachian State University alumnus Chris Waldon’s favorite aspect of his job is working with great people who inspire him. “I’m surrounded by brilliant software engineers, and I get to learn from them daily,” he said.

    It is not surprising that Waldon ’16 ’18 still has a thirst for learning. He graduated summa cum laude from Appalachian with a Bachelor of Science in computer science in 2016, was an Honors College student as well as a Chancellor’s Scholar, and earned his Master of Science in computer science in 2018.


    Outside of class, Waldon started Linux@App, a club for students interested in using the Linux operating system — an alternative to macOS or Windows. “You can do a lot with Linux that isn’t possible on other systems,” Waldon explained. “Since most of the internet and all of the systems I use at IBM run on Linux, learning and teaching about it at Appalachian helped me develop the practical skill I now use daily.”

    This year’s version of curl up started a little differently: With an afternoon of HTTP presentations. The event took place the same week the IETF meeting has just ended here in Prague so we got the opportunity to invite people who possibly otherwise wouldn’t have been here… Of course this was only possible thanks to our awesome sponsors, visible in the image above!

    Lukáš Linhart from Apiary started out with “Web APIs: The Past, The Present and The Future”. A journey trough XML-RPC, SOAP and more. One final conclusion might be that we’re not quite done yet…

    James Fuller from MarkLogic talked about “The Defenestration of Hypermedia in HTTP”. How HTTP web technologies have changed over time while the HTTP paradigms have survived since a very long time.

  • Will Kahn-Greene: Code of conduct: supporting in projects

    This week, Mozilla added PRs to all the repositories that Mozilla has on GitHub that aren't forks, Servo, or Rust. The PRs add a CODE_OF_CONDUCT.md file and also include some instructions on what projects can do with it. This standardizes inclusion of the code of conduct text in all projects.

    I'm a proponent of codes of conduct. I think they're really important. When I was working on Bleach with Greg, we added code of conduct text in September of 2017. We spent a bunch of time thinking about how to do that effectively and all the places that users might encounter Bleach.

  • Speakeasy: Commercial Interests

    This month, the World Wide Web turned 20, and its birthday was celebrated the world over. It was a pleasant change since the medium, once a new frontier of hope, has been regarded with suspicion ever since the Cambridge Analytica scandal broke. We had spent years outraging over the possibility that our choice of washing machines and underwear was being conditioned by smart web advertising, and, in 2018, we learned that even voter choice was open to manipulation. That marked another anniversary — the silver jubilee of feeling small, lost and sandbagged by the internet. Because before the web, the net was full of command-line cowboys and cowgirls, most of whom had just come online, and were very hopeful and a little lost.
    Twenty-five years ago, before the visual web, which is like a picturesque window onto the internet, there was the internet itself in its raw, minimalist beauty — the beauty of the blank command line. It was beautiful if you knew what to type into it, and magically, a server on another continent would respond to your UNIX command. The command line is what Indians saw when they first accessed the internet in the mid-Nineties, with ordinary phone lines and modems with lots of flashing lights. If you were hip, it was a 14.4 Kbps modem. If you weren’t, it was just 9.6 Kbps — in contemporary terms, about the speed of an incredibly slow Torrent that would take two weeks to download a pirated film. It was the era of internet evangelism in search of critical mass, led by personalities like Miheer Mafatlal (now indistinguishable from Merlin), Shammi Kapoor (then at home at father.junglee.org.in) and Vijay Mukhi. It was also the era of common folk who could not even afford an internet connection, and instead dialled into private bulletin boards to chat, download software and access email, the killer app of the internet for over a decade, until the birth of social media. People chatted and mailed a bit, and hardly ever surfed with the now-forgotten Netscape Navigator, whose genetic code lives on in Mozilla Firefox. Surfing was excruciating training in Zen patience, since download speeds of one byte per second were sometimes reported.

  • Senators demand to know why election vendors still sell voting machines with ‘known vulnerabilities’ [Ed: Former Microsoft employee Zack Whittaker wonders aloud why voting machines come with Microsoft back doors for the NSA (and other nations, underworld)

    Four senior senators have called on the largest U.S. voting machine makers to explain why they continue to sell devices with “known vulnerabilities,” ahead of upcoming critical elections.

    The letter, sent Wednesday, calls on election equipment makers ES&S, Dominion Voting and Hart InterCivic to explain why they continue to sell decades-old machines, which the senators say contain security flaws that could undermine the results of elections if exploited.

    “The integrity of our elections is directly tied to the machines we vote on,” said the letter sent by Sens. Amy Klobuchar (D-MN), Mark Warner (D-VA), Jack Reed (D-RI) and Gary Peters (D-MI), the most senior Democrats on the Rules, Intelligence, Armed Services and Homeland Security committees, respectively. “Despite shouldering such a massive responsibility, there has been a lack of meaningful innovation in the election vendor industry and our democracy is paying the price,” the letter adds.

  • Brace yourselves: Exploit published for serious Magento bug allowing card skimming

    Attack code was published on Friday that exploits a critical vulnerability in the Magento e-commerce platform, all but guaranteeing it will be used to plant payment card skimmers on sites that have yet to install a recently released patch.

    PRODSECBUG-2198 is a SQL injection vulnerability that attackers can exploit with no authentication required. Hackers could exploit the flaw to take administrative control of administrator accounts, assuming the hackers can download user names and password hashes and crack the hashes. From there, attackers could install the backdoors or skimming code of their choice. A researcher at Web security firm Sucuri said Thursday that company researchers reverse-engineered an official patch released Tuesday and successfully created a working proof-of-concept exploit.
