  • Rationalizing Python's APIs

    CPython is the reference implementation of Python, so it is, unsurprisingly, the target for various language-extension modules. But the API and ABI it provides to those extensions ends up limiting what alternative Python implementations—and even CPython itself—can do, since those interfaces must continue to be supported. Beyond that, though, the interfaces are not clearly delineated, so changes can unexpectedly affect extensions that have come to depend on them. A recent thread on the python-ideas mailing list looks at how to clean that situation up.

    On July 11, Victor Stinner floated a draft of an as yet unnumbered Python Enhancement Proposal (PEP) entitled "Hide implementation details in the C API". The idea is to remove CPython implementation choices from the API so that different experimental choices can be made while still supporting the C-based extensions (NumPy and SciPy in particular). As he noted, other attempts to provide an alternate Python implementation (e.g. PyPy), which are typically created to enhance the language's performance, have largely run aground because they cannot directly support these all-important extensions.

  • Ideas versus implementation

    A short sub-thread on the python-ideas mailing list provides some "food for thought" about the purpose and scope of that list, but also some things to perhaps be considered more widely. When discussing new features and ideas, it is common for the conversation to be somewhat hypothetical, but honing in on something that could be implemented takes a fair amount of work for those participating. If the feature is proposed and championed by someone who has no intention of actually implementing it, should the thread come with some kind of warning?

    The thread in question started in mid-June with a query from Thomas Güttler about why the socket module returns plain tuples rather than named tuples. The reception to the idea was mostly positive and there were some discussions of how it might be done; Guido van Rossum indicated that he would be favorable to the change as well. But, apparently Güttler was not actually planning to implement the change, as he currently does not have the time to do so.

  • Tired: Java. Desired: Node.js. Retired: The suggestion a JavaScript runtime is bonkers

    As the Node Summit got underway in San Francisco on Wednesday, Charles Beeler, general partner at Rally Ventures, said the Node community has come a long way since 2012, when everyone was talking about Node.js and no one was using it.

    Initially released in 2009, the JavaScript runtime environment now has enough users and momentum that the nonprofit Node.js Foundation feels comfortable claiming that "Node.js is emerging as a universal development framework for digital transformation with a broad diversity of applications."

  • Software Development as mathematician in academia – everyone bites the dust

    Is it possible to do software development, mathematical or not, as mathematician in academics? This is a question I was asking myself recently a lot, seeing my own development from logician at a state university getting rid of foreigners to software developer. And then, a friend pointed me to this very depressing document: The origins of SageMath by William Stein, the main developer of SageMath. And I realized that it seems to be a global phenomenon that mathematicians who are interested in software development have to leave academics. What a sad affair.

    [...]

    My assumption was that this hits only on non-tenured staff, the academic precariat. It is shocking to see that even William Stein with a tenure position is leaving academics.

  • Qualcomm's neural network SDK made free for all comers [Ed: Proprietary still. Free as in "lockin".]/

    TensorFlow is also name-checked in the announcement, and since the SDK's page also mentions convolutional neural network support, Vulture South reckons Cuda ConvaNet (part of last year's announcement) is also in there somewhere.

  • GitHub wants more new contributors, because that's what GitHub is for

    GitHub has added a chunk of features it says will help new users and projects build better communities.

    Singing the “teamwork” song, the organisation says the features announced here are about making it easier to contribute to projects.

    For project maintainers, new contributors will show a “first time contributor badge” attached to their pull requests. That will become a “contributor” badge when the PR is merged, and there's an additional flag to help maintainers “separate signal from noise” during flamewars (politely described by GitHub as “lengthy or heated discussions”).

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
