Moment.js announces legacy status

수, 2020/09/16 - 12:02오전

Moment.js, the de facto standard JavaScript library for date and time manipulation, has announced that "we would like to discourage Moment from being used in new projects going forward." The project cited multiple reasons for the recommendation. The first is that moment objects are mutable; another is the unnecessarily large size of the library when compared to other internationalization and time-zone support options available to modern browsers. According to the post, "we now generally consider Moment to be a legacy project in maintenance mode. It is not dead, but it is indeed done." The project offers multiple recommendations of alternative options, including "the evolution of Moment", Luxon, authored by long-time Moment.js contributor Isaac Cambron.

[$] Modernizing the tasklet API

화, 2020/09/15 - 12:39오전
Tasklets offer a deferred-execution method in the Linux kernel; they have been available since the 2.3 development series. They allow interrupt handlers to schedule further work to be executed as soon as possible after the handler itself. The tasklet API has its shortcomings, but it has stayed in place while other deferred-execution methods, including workqueues, have been introduced. Recently, Kees Cook posted a security-inspired patch set (also including work from Romain Perrier) to improve the tasklet API. This change is uncontroversial, but it provoked a discussion that might lead to the removal of the tasklet API in the (not so distant) future.

[$] OpenPGP in Rust: the Sequoia project

토, 2020/09/12 - 1:06오전
In 2018, three former GnuPG developers began work on Sequoia, a new implementation of OpenPGP in Rust. OpenPGP is an open standard for data encryption, often used for secure email; GnuPG is an implementation of that standard. The GPLv2-licensed Sequoia is heading toward version 1.0, with a handful of issues remaining to be addressed. The project's founders believe that there is much to be desired in GnuPG, which is the de facto standard implementation of OpenPGP today. They hope to fix this with a reimplementation of the specification using a language with features that will help protect users from common types of memory bugs.

[$] Android kernel notes from LPC 2020

금, 2020/09/11 - 1:55오전
In its early days, the Android project experienced a high-profile disconnect with the kernel community. That situation has since improved considerably, but there are still differences between Android kernels and the mainline. As a result, it is not possible to run Android on a vanilla kernel. That situation continues to improve, though; much evidence to that effect was on display during the Android microconference at the 2020 Linux Plumbers Conference. Several sessions there showed the progress that is being made toward unifying the Android and mainline kernels — and the places where there is still some work to be done.

[$] Preparing for the realtime future

목, 2020/09/10 - 7:47오전
Unlike many of the previous gatherings of the Linux realtime developers, their microconference at the virtual 2020 Linux Plumbers Conference had a different feel about it. Instead of being about when and how to get the feature into the mainline, the microconference had two sessions that looked at what happens after the realtime patches are upstream. That has not quite happened yet, but is likely for the 5.10 kernel, so the developers were looking to the future of the stable realtime trees and, relatedly, plans for continuous-integration (CI) testing for realtime kernels.

[$] Lua in the kernel?

목, 2020/09/10 - 1:17오전
BPF is, of course, the language used for network (and other) customization in the Linux kernel, but some people have been using the Lua language for the networking side of that equation. Two developers from Ring-0 Networks, Lourival Vieira Neto and Victor Nogueira, came to the virtual Netdev 0x14 to present that work. It consists of a framework to allow the injection of Lua scripts into the running kernel as well as two projects aimed at routers, one of which is deployed on 20 million devices.

Rosenzweig: Fun and Games with Exposure Notifications

수, 2020/09/09 - 2:31오전
Alyssa Rosenzweig looks at getting the Exposure Notifications System protocol, developed by Apple and Google for facilitating COVID-19 contact tracing on Android and iOS phones, running on GNU/Linux. "All in all, we end up with a Linux implementation of Exposure Notifications functional in Ontario, Canada. What’s next? Perhaps supporting contact tracing systems elsewhere in the world – patches welcome." The source code for liben is available "for any one who dares go near".

[$] Conventions for extensible system calls

화, 2020/09/08 - 11:50오후
The kernel does not have just one system call to rename a file; instead, there are three of them: rename(), renameat(), and renameat2(). Each was added when the previous one proved unable to support a new feature. A similar story has played out with a number of system calls: a feature is needed that doesn't fit into the existing interfaces, so a new one is created — again. At the 2020 Linux Plumbers Conference, Christian Brauner and Aleksa Sarai ran a pair of sessions focused on the creation of future-proof system calls that can be extended when the need for new features arises.
