  • Nicholas Nethercote: Visualizing Rust compilation

    Speeding up the Rust compiler isn’t the only way to make a Rust project build faster. Changing the crate structure of a project can also make a big difference. The good news here is that Eric Huss has implemented an amazing tool for visualizing Rust compilation, which can be used to identify inefficient crate structures in Rust projects.

  • RcppArmadillo 0.9.800.1.0

    Another month, another Armadillo upstream release! Hence a new RcppArmadillo release arrived on CRAN earlier today, and was just shipped to Debian as well. It brings a faster solve() method and other goodies. We also switched to the (awesome) tinytest unit test frameowrk, and Min Kim made the configure.ac script more portable for the benefit of NetBSD and other non-bash users; see below for more details. One again we ran two full sets of reverse-depends checks, no issues were found, and the packages was auto-admitted similarly at CRAN after less than two hours despite there being 665 reverse depends. Impressive stuff, so a big Thank You! as always to the CRAN team.

  • Anaconda Enters a New Chapter

    Today I am excited to announce that I am stepping into the role of CEO at Anaconda. Although I am a founder of the company and have previously served as president, this marks the first time I am serving in the role of chief executive.

    The entire world is undergoing a revolution in computation and data analytics — a revolution that we helped start almost 10 years ago, at the dawn of modern data science.

    [...]

    I am very appreciative of our previous CEO Scott Collison. Under his leadership, we grew from an open-source consultancy into a true product company, put a world-class leadership team in place, and launched our enterprise machine learning platform. He made a lasting impact on our company’s evolution.

  • Emacs: The Best Python Editor?

    Finding the right code editor for Python development can be tricky. Many developers explore numerous editors as they grow and learn. To choose the right code editor, you have to start by knowing which features are important to you. Then, you can try to find editors that have those features. One of the most feature-rich editors available is Emacs.

    Emacs started in the mid-1970s as a set of macro extensions for a different code editor. It was adopted into the GNU project by Richard Stallman in the early 1980s, and GNU Emacs has been continuously maintained and developed ever since. To this day, GNU Emacs and the XEmacs variant are available on every major platform, and GNU Emacs continues to be a combatant in the Editor Wars.

6 Best Free Linux Web Caches

Hypertext Transfer Protocol (HTTP) is considered to be the fundamental protocol of the web. This simple request/response protocol is used for distributed, collaborative, hypermedia information systems. The web consumes a large portion of internet traffic. With HTTP, a client makes a request for a resource to a server, and the server delivers messages with additional content such as images, style sheets and JavaScript. HTTP dictates how these messages are displayed and transmitted, and how web servers and browsers should respond to various commands. The developers of the HTTP protocol realized at an early stage that there was going to be rapid growth in web traffic. This continues to be the case. Read more

  • Submit a KSyntaxHighlighting Color Theme

    The KSyntaxHighlighting framework provides support for color themes. These color themes specify all colors (text/background/selection/…) and font style roles (italic/bold/…) that are used for the highlighting. The definition happens in some easy to understand JSON file format. Starting with the upcoming KDE Frameworks 5.75 release, all KTextEditor framework based application will support these color themes for their embedded editors. This includes Kate & KWrite, but naturally a lot more, like for example KDevelop, Kile and RKWard. [...] With the recent additions we already cover some more well known text editor color themes. But if you just search a bit around the internet or look what other text editors ship per default, we still lack a lot of well known ones. For example even our GitLab instance provides the Monokai theme in the configuration for its web highlighting that we still lack. Therefore, we are eager to get submissions for more MIT licensed color themes we can bundle with KSyntaxHighlighting. All users of applications using this framework will enjoy to be able to choose between more themes with ease if you help us! Therefore, take the chance and help us out, provide some more themes as merge request. License must be MIT, this seems to be no problem for most themes out there, at least it seems most of the ones I stumbled over are MIT licensed.

  • FreeBSD Instant-workstation 2020

    A little over a year ago I published an instant-workstation script for FreeBSD. The idea is to have an installed FreeBSD system, then run a shell script that uses only base-system utilities and installs and configures a workstation setup for you. [...] The script is updated intermittently when new PRs come in, or when I have to reinstall a machine and things do not behave the way I think they should. If you want a quick live KDE Plasma experience with FreeBSD, head on over to FuryBSD which does live ISO images with a variety of environments.

  • Three tips to implement Kubernetes with open standards

    The technologies chosen by enterprise IT departments today will have a long-term impact on their performance, operations and overall strategy. Sometimes it can take well over a decade to realize the full implications of a technology solution. This can put a great deal of weight on the shoulders of IT management, especially when it comes to emergent technologies whose utility, importance and trajectory may not yet be fully known. Placing a bad bet on new software can lead to difficult integrations and disruptions across an organisation’s entire tech stack, which in the long-term can lead to lost productivity, wasted budgets, and the likelihood of losing ground to competitors. Kubernetes, the open source container orchestration platform, was until recently regarded in the same way, with IT departments struggling to fully appraise its long-term value. However, with Kubernetes now running 86 per cent of container clusters, it has emerged as the de facto standard for cloud-native infrastructure. This means that the main concern for IT departments is not whether Kubernetes has a future, but how to ensure that their implementation of Kubernetes has a future which doesn't present a bottleneck to integrations, industry practices and use cases.

  • The Expandables – snapcraft extensions and the secret code

    If you’re a snap developer, you know that snap development is terribly easy. Or rather complex and difficult. Depending on your application code and requirements, it can take a lot of effort putting together the snapcraft.yaml file from which you will build your snap. One of our goals is to make snap development practically easier and more predictable for everyone. To that end, we created a framework of snap extensions, designed to make the snap journey simpler and more fun. In a nutshell, extensions abstract away a range of common code declarations you would normally put in your snapcraft.yaml file. They help developers avoid repetitive tasks, reduce the knowledge barrier needed to successfully build snaps, offer a common template for application builds, and most importantly, save time and effort. But what if you want – or need – to know what is behind the abstraction?

  • Researchers were able to figure out which American phone numbers use Signal
           
             

    Privacy flaws in contact discovery have led to a research team being able to enumerate all American Signal users. Enumeration means that using the contact discovery built into the Signal app, researchers were able to perform a large-scale crawling attack and figure out which American phone numbers were attached to a Signal account. The new research paper was released by Christoph Hagen, Christian Weinert, Christoph Sendner, Alexandra Dmitrienko, and Thomas Schneider. It is titled: “All the Numbers are US: Large-scale Abuse of Contact Discovery in Mobile Messengers.”

  • The ’90s are back: Gateway laptops have been resurrected as Walmart exclusives

    Remember Gateway laptops? If you grew up in the ’90s, they were probably the brand of your first laptop. Like a revival of your favorite childhood television show, the Gateway brand has been raised from the dead — cow imagery and all. The brand, which is owned by computer maker Acer, is making its own comeback with a line of new laptops, tablets, and convertibles that will be exclusive to Walmart.

    So, what’s forcing these cows out of hibernation? For Gateway parent Acer, its about new silicon from Intel and AMD, including the successsul new mobile Ryzen 4000 processors.
