DebConf20: offer to speak in Palestine censored

On 20 December 2019, a Debian Developer posted the message below to the debian-project mailing list, offering to give the same talk at both DebConf20 in Haifa, Israel and again in Palestine. The message never appeared in the list and can't be found in the list archive for December. Alexander Wirt (formorer) has previously declared that he will censor messages about Israel due to anti-semitism. Yet the message below doesn't include anything against Israel and doesn't mention the boycott campaign. It is simply a volunteer offering to give up more of his time to help a population in Palestine who suffer from extraordinary discrimination. Is Wirt really fighting anti-semitism, or could the DebConf20 organizers simply be afraid of any discussion that may deter wealthy Israeli sponsors? Read more

    The real reason Rocket League is dropping support for Linux, Wine has a massive release, and the potential for Canonical's new Android in the cloud service. Plus, our take on the FSF's Upcycle Windows 7 campaign, and the clever Chrome OS strategy upgrade for education in 2020.

  • Open Source Security Podcast: Episode 180 - A Tale of Two Vulnerabilities

    Josh and Kurt talk about two recent vulnerabilities that have had very different outcomes. One was the Citrix remote code execution flaw. While the flaw is bad, the handling of the flaw was possibly worse than the flaw itself. The other was the Microsoft ECC encryption flaw. It was well handled even though it was hard to understand and it is a pretty big deal. As all these things go, fixing and disclosing vulnerabilities is hard.

    The **acct** command from the Slackware **ap** software series.

  • Podcast.__init__: Simplifying Social Login For Your Web Applications

    A standard feature in most modern web applications is the ability to log in or register using accounts that you already own on other sites such as Google, Facebook, or Twitter. Building your own integrations for each service can be complex and time consuming, distracting you from the features that you and your users actually care about. Fortunately the Python social auth library makes it easy to support third party authentication with a large and growing number of services with minimal effort. In this episode Matías Aguirre discusses his motivation for creating the library, how he has designed it to allow for flexibility and ease of use, and the benefits of delegating identity and authentication to third parties rather than managing passwords yourself.

Linux 5.5

So this last week was pretty quiet, and while we had a late network
update with some (mainly iwl wireless) network driver and netfilter
module loading fixes, David didn't think that warranted another -rc.
And outside of that, it's really been very quiet indeed - there's a
panfrost driver update too, but again it didn't really seem to make
sense to delay the final release by another week.

Outside of those, it's all really tiny, even if some of those tiny
changes touched some core files.

So despite the slight worry that the holidays might have affected the
schedule, 5.5 ended up with the regular rc cadence and is out now.

That means that the merge window for 5.6 will open tomorrow, and I
already have a couple of pull requests pending. The timing for this
next merge window isn't optimal for me - I have some travel and other
things going on during the same two weeks, but hopefully it won't be
all that noticeable.  But there might be random timezones, odd hours,
and random delays because of that. I try to avoid scheduling things
during the merge window, but hey, it doesn't always work out, and I'd
have to delay things by two weeks to avoid the conflicts, which just
doesn't seem worth it.

Particularly since it's not necessarily going to be a problem to begin
with. We'll see.

Anyway. Go out and test 5.5, and start sending me those pull requests
for all the new development that is ready,

                    Linus
