## [$] Catching up with calibre
**Category:** Linux  
**Tags:** General  
**Published:** Wed, 02 Apr 2025 17:00:38 +0000  
**TL;DR:** Here is a summary of the text in 2 sentences:

Calibre is an open-source software that goes beyond just managing eBooks, offering a range of features such as creating eBooks, converting formats, and serving eBook libraries over the web. The latest release, calibre 8.0, adds new features like a better text-to-speech engine, audio overlay creation for authoring eBooks, and profile support in the eBook viewer.  
<p>Saying that <a href="https://calibre-ebook.com/">calibre</a> is
ebook-management software undersells the application by a fair
margin. Calibre is an open-source Swiss Army knife for ebooks that can
be used for everything from creating ebooks, converting ebooks from
obscure formats to modern formats like EPUB, to serving up an ebook
library over the web. The most recent major release, <a href="https://calibre-ebook.com/new-in/seventeen">calibre&#160;8.0</a>,
brings a better text-to-speech engine, a tool for creating audio
overlays when authoring ebooks, support for profiles in the ebook
viewer, and more.</p>

## [$] An update on GCC BPF support
**Category:** Linux  
**Tags:** General  
**Published:** Wed, 02 Apr 2025 15:47:39 +0000  
**TL;DR:** Here is a summary of the text in 2 sentences:

José Marchesi and David Faust presented an update on their work to support compiling to BPF (Berkeley Packet Filter) in GCC, with most self-tests now passing using Faust's patches. However, their progress uncovered issues with how Clang supports BPF, which required a detailed discussion to find a path forward for both projects.  
<p>
José Marchesi and David Faust kicked off the BPF track at the 2025 Linux Storage,
Filesystem, Memory-Management, and BPF Summit with an extra-long session on what
they have been doing to support compiling to BPF in GCC. Overall, the project is slowly working
toward full support for BPF, with most of the self-tests now passing using
Faust's in-progress patches. However, the progress toward that goal has turned up
a number of problems with how Clang supports BPF that needed to be discussed at
length to find a path forward for both projects.

## Thunderbird plans "Thundermail" email and other services
**Category:** Linux  
**Tags:** General  
**Published:** Wed, 02 Apr 2025 15:39:07 +0000  
**TL;DR:** Here is a 2-sentence summary:

Ryan Sipes, managing director of product for Thunderbird's parent organization MZLA Technologies Corporation, has announced plans to expand Thunderbird's offerings with web services aimed at enhancing the email client experience. The planned services include hosted email, appointment scheduling, an AI assistant based on a partnership with Flower AI, and a revival of Firefox Send, all designed to create a 100% open source alternative ecosystem to compete with Gmail and Office365.  
<p>Ryan Sipes has <a href="https://thunderbird.topicbox.com/groups/planning/T437cd854afcb1395">announced</a>
efforts to expand Thunderbird's offerings with web services to
"<q>enhance the experience of using Thunderbird</q>".</p>

<blockquote class="bq">
The Why for offering these services is simple. Thunderbird loses users
each day to rich ecosystems that are both clients and services, such
as Gmail and Office365. These ecosystems have both hard vendor
lock-ins (through interoperability issues with 3rd-pary clients) and
soft lock-ins (through convenience and integration between their
clients and services). It is our goal to eventually have a similar
offering so that a 100% open source, freedom-respecting alternative
ecosystem is available for those who want it.
</blockquote>

<p>The planned services include hosted email, appointment scheduling,
a revival of <a href="https://en.wikipedia.org/wiki/Firefox_Send">Firefox Send</a>,
and (of course) an AI assistant based on a partnership with <a href="https://flower.ai/">Flower AI</a>. The AI features will
"<q>always be optional for use by people who want them</q>". Sipes is
managing director of product for Thunderbird's parent organization, <a href="https://blog.thunderbird.net/2020/01/thunderbirds-new-home/">MZLA

<p>Outgoing Fedora Project Leader (FPL) Matthew Miller has <a href="https://fedoramagazine.org/introducing-fedora-project-leader-jef-spaleta/">announced</a>
his successor, Jef Spaleta.</p>

<blockquote class="bq">
<p>Some of you may remember Jef's passionate voice in the early Fedora
community. He got involved all the way back in the days of fedora.us,
before Red Hat got involved. Jef served on the Fedora Board from July
2007 through the end of 2008. This was the critical time after Fedora
Extras and Fedora Core merged into one Fedora Linux where, with the
launch of the "Features" process, Fedora became a truly community-led
project.</p>

<p>Spaleta will be joining Red Hat full time in May and Miller will be
formally handing off FPL duties at the <a href="https://fedoraproject.org/flock/2025/">Flock</a> conference in
