As shown above, there are cases where match really shines. But they are few and far between, mostly when handling syntax trees and writing parsers. A lot of code does have if ... elif chains, but these are often either plain switch-on-value, where elif works almost as well, or the conditions they’re testing are a more complex combination of tests that don’t fit into case patterns (unless you use awkward case _ if cond clauses, but that’s strictly worse than elif).

(Pattern matching has been covered here as well).

Hi,
thank you for attending LPC 2021!
We have now reached our limit for attendees. Registration is now closed.
If you are still intending to watch the conference you can do this by watching on YouTube.

So I've spent a fair amount of this week trying to sort out all the odd warnings, and I want to particularly thank Guenter Roeck for his work on tracking where the build failures due to -Werror come from.

Is it done? No. But on the whole I'm feeling fairly good about this all, even if it has meant that I've been looking at some really odd and grotty code. Who knew I'd still worry about some odd EISA driver on alpha, after all these years? A slight change of pace ;)

The LPC 2021 conference is just around the corner. We wanted to share the logistics on how to participate and watch the virtual conference.

For those that are not registered for the conference, we will have live streaming of the sessions on YouTube, like last year. This is free of charge. We will provide the URLs where to watch each day, on this page. The only limitation is that you cannot participate and ask questions live with audio. However this year we will have the chat in each Big Blue Button room also available externally via the Matrix open communication network. Anyone is invited to join with their personal Matrix account.

Those who are registered for the conference will be able to log into our Big Blue Button server through our front end page, starting Monday September 20 at 7:00AM US Pacific time.
To log in to BBB, please go to meet.lpc.events. You will find a front end showing the schedule for the current day with all the active sessions you can join. Your credentials are the email address you used for registration, and the confirmation code you received in email when you registered. Please make sure you have those available in advance of trying to log in.

Please review the LPC 2021 Participant Guide before you join the conference.

Looking forward to seeing you there!

And I know some people will wonder why we spent so much time working with NVidia around their binary driver, but the reality is that NVidia is the market leader, especially in the professional Linux workstation space, and there are lot of people who either would end up not using Linux or using Linux with X without it, including a lot of Red Hat customers and Fedora users. And that is what I and my team are here for at the end of the day, to make sure Red Hat customers are able to get their job done using their Linux systems.

For distributions, however, the story is different: cryptography moved to using Rust, because they wanted to leverage all of the static analysis capabilities built into the language. This, too, is a reasonable decision, from a development perspective. From the ecosystem perspective, however, it is problematic, as the Rust ecosystem is still rapidly evolving, and so we cannot support a single branch of the Rust compiler for an entire 2 year lifecycle, which means it exists in community. Our solution, historically, has been to hold cryptography at the latest version that did not require Rust to build. However, that version is not compatible with OpenSSL 3, and so it will eventually need to be upgraded to a new version which is. And so, since cryptography has to move to community, so does paramiko and Ansible.

We are only three days away from the start of LPC 2021!

Thank you to all that made our conference possible:
– Our generous Sponsors, listed here on the right
– The Linux Foundation, which provides as always impeccable support
– Our speakers and leaders, who are providing a lot of great content and planning great discussions

As you can see, the schedule is finalized now. There are going to be seven parallel tracks each day, lasting four hours each. We have a total of 23 different tracks and Microconferences, with 191 sessions.

At this time we are closing the CfPs for all tracks. We have still room for a limited number of Birds of a Feather sessions. If you want to propose one, even during the conference, and the necessary participants are all registered, please send an email to our lpc-contact@lists.linuxplumbersconf.org mailing list.

Take a look at all the great technical content at this year virtual LPC.
You can view the schedule by main blocks , or by track, or as a complete detailed view.

Note that at the end of the first day we’ll have a plenary keynote by Jon “maddog” Hall.
Additionally, at the end of the last day we’ll have a plenary session as a wrap up for this year conference.

The conference will be entirely virtual, offered on a completely free and open software stack.

We look forward to five days filled with great discussions, and we hope that LPC 2021 will provide once again a creative and productive environment where ideas can be exchanged and problems tackled. Many great ideas have sprung in the past from these meetings, driving innovation in the Linux plumbing layer!

A security flaw in Travis CI potentially exposed the secrets of thousands of open source projects that rely on the hosted continuous integration service. Travis CI is a software-testing solution used by over 900,000 open source projects and 600,000 users. A vulnerability in the tool made it possible for secure environment variables—signing keys, access credentials, and API tokens of all public open source projects—to be exfiltrated.

Any project storing secrets in this service would be well advised to replace them.
