  • 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

  • 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.

Programming and HowTos: The Leftovers

Gustavo Silva: Disco Dingo Thoughts

Those already around me know I love Linux and my favourite linux distribuition is Ubuntu. One of the reasons Ubuntu is my favourite is how simple and compatible it is with pretty much all devices I have tried installing. Except my laptop, but that’s due to the graphics card. But hey, I fondly received the news that now we can select the option to automatically set nomodeset and other convenient tools when running the setup. For me, this means a major win. I previously had to set nomodeset manually and after installation I had to immediately modifiy some options in the grub’s defaults (namely set the acpi=force) but now, with this new option, the installation process which was already smooth, become (melted) butter. Thank you, honestly, person who remembered to include this option. This seems like a feature that will stick to Ubuntu 20.04, so I’m happy to now a LTS version will become even simpler to install too, so that’s great. The UI and custom-Gnome experience has been improved as well, in this custom flavour of Gnome. We now have a few more options for customization, including dark options of the themes but I am definitely pleased to say that the Gnome shell, in Ubuntu 19.04, really looks great. Read more

5 of the Best Linux Desktops for Touchscreen Monitors in 2019

The concept of using Linux on a touchscreen monitor or two-in-one computer has come a long way. Touchscreen support is now built into the Linux kernel, so theoretically any Linux distribution should run with a touchscreen. That said, not every distribution will be easy to use on a touchscreen, and this comes down to the desktop. For example, using a tiling window manager like Awesome or i3 isn’t going to do you much good on a touchscreen. Choose the right desktop (more precisely, desktop environment), and you’ll have a much better time using Linux with a touchscreen. Read more
