[$] Building a Flutter application (part 1)

목, 2020/08/13 - 1:59오전
In this two-part series, we will be implementing a simple RSS reader for LWN using the UI toolkit Flutter. The project recently announced version 1.20 of the toolkit on August 5. Flutter is a BSD-licensed UI development platform written in Dart that is backed by Canonical as a new way to develop desktop applications targeting Linux. Part one will cover some of the basics of the project and Flutter, with part two building on that work to focus on building a full interactive UI for the application.

[$] Local locks in the kernel

수, 2020/08/12 - 6:10오전
The Linux kernel has never lacked for synchronization primitives and locking mechanisms, so one might justifiably wonder why there might be a need to add another one. The addition of local locks to 5.8 provides an answer to that question. These locks, which have their origin in the realtime (PREEMPT_RT) tree, were created to solve some realtime-specific problems, but they also bring some much-needed structure to a common locking pattern used in non-realtime kernels as well.

Baker: Changing World, Changing Mozilla

수, 2020/08/12 - 3:54오전
Mitchell Baker writes about changes at Mozilla, headlined by the laying-off of 250 people. "Recognizing that the old model where everything was free has consequences, means we must explore a range of different business opportunities and alternate value exchanges. How can we lead towards business models that honor and protect people while creating opportunities for our business to thrive? How can we, or others who want a better internet, or those who feel like a different balance should exist between social and public benefit and private profit offer an alternative?"

[$] End-to-end network programmability

화, 2020/08/11 - 7:20오전
Nick McKeown kicked off the virtual Netdev 0x14 conference with a talk on extending the programmability of networking equipment well beyond where it is today. His vision is of an end-to-end system with programmable pieces at every level. Getting there will require collaboration between the developers of the networking stacks on endpoint operating systems as well as those of switches, routers, and other backbone equipment. The keynote was held on July 28, a little over two weeks before the seven days of talks, workshops, and tutorials for Netdev, which begins on August 13.

On Perl 7 and the Perl Steering Committee

일, 2020/08/09 - 1:53오전
For those who are wondering about the state of the proposed Perl 7 fork and the role of the newly formed Perl Steering Committee, Ricardo Signes has put together a detailed explanation that is worth a read. "You should not expect to see a stream of unjustified dictates issuing forth from some secret body on high. You should expect to see perl5-porters operating as it generally did: with proposals coming to the list, getting discussion, and then being thumbed up or down by the project manager. This is what has been happening for years, already. Some proposals were already discussed by the project manager and some were not. If you eliminated any named mailing list for doing this, it would still happen. The PSC is a means to say that there is a default group for such discussions. If you were wondering, its initial membership was formed from 'the people who came to or were invited to the Perl Core Summit' over the last few years."
