Python 3.14.0 alpha 3 is out

Posted on December 18, 2024 by Michael G

O Alpha 3, O Alpha 3, how lovely are your branches!

https://www.python.org/downloads/release/python-3140a3/

This is an early developer preview of Python
3.14

Major
new features of the 3.14 series, compared to 3.13

Python 3.14 is still in development. This release, 3.14.0a3, is the
third of seven planned alpha releases.

Alpha releases are intended to make it easier to test the current
state of new features and bug fixes and to test the release process.

During the alpha phase, features may be added up until the start of
the beta phase (2025-05-06) and, if necessary, may be modified or
deleted up until the release candidate phase (2025-07-22). Please keep
in mind that this is a preview release and its use is
not recommended for production environments.

Many new features for Python 3.14 are still being planned and
written. Among the new major new features and changes so far:

  • PEP 649: deferred
    evaluation of annotations
  • PEP 741: Python
    configuration C API
  • PEP 761: Python 3.14
    and onwards no longer provides PGP signatures for release artifacts.
    Instead, Sigstore is recommended for verifiers.
  • Improved
    error messages
  • (Hey, fellow core developer, if a feature
    you find important is missing from this list, let Hugo
    know.)

The next pre-release of Python 3.14 will be 3.14.0a4, currently
scheduled for 2025-01-14.

And now for
something completely different

A mince pie is a small, round covered tart filled with “mincemeat”,
usually eaten during the Christmas season – the UK consumes some 800
million each Christmas. Mincemeat is a mixture of things like apple,
dried fruits, candied peel and spices, and originally would have
contained meat chopped small, but rarely nowadays. They are often served
warm with brandy butter.

According to the Oxford English Dictionary, the earliest mention of
Christmas mince pies is by Thomas Dekker, writing in the aftermath of
the 1603
London plague
, in Newes
from Graues-end: Sent to Nobody
(1604):

Ten thousand in London swore to feast their neighbors with nothing
but plum-porredge, and mince-pyes all Christmas.

Here’s a meaty recipe from Rare
and Excellent Receipts, Experienc’d and Taught by Mrs Mary Tillinghast
and now Printed for the Use of her Scholars Only
(1678):

  1. How to make Mince-pies.

To every pound of Meat, take two pound of beef Suet, a pound of
Corrants, and a quarter of an Ounce of Cinnamon, one Nutmeg, a little
beaten Mace, some beaten Colves, a little Sack & Rose-water, two
large Pippins, some Orange and Lemon peel cut very thin, and shred very
small, a few beaten Carraway-seeds, if you love them the Juyce of half a
Lemon squez’d into this quantity of meat; for Sugar, sweeten it to your
relish; then mix all these together and fill your Pie. The best meat for
Pies is Neats-Tongues, or a leg of Veal; you may make them of a leg of
Mutton if you please; the meat must be parboyl’d if you do not spend it
presently; but if it be for present use, you may do it raw, and the Pies
will be the better.

Enjoy the new release

Thanks to all of the many volunteers who help make Python Development
and these releases possible! Please consider supporting our efforts by

How to get started on open-source development

Posted on December 18, 2024 by Michael G

Open-source technology isn’t just about building software — it’s about creating solutions collaboratively, making them freely available for anyone to use and adapt. This approach lowers barriers of access and allows solutions to be tailored to varying nuanced contexts rather than applying a copy-paste approach.  I come from a family with a heavy engineering background. […]

Making Chrome QUICer

Posted on December 18, 2024 by Michael G

In October 2020, Chrome enabled HTTP/3 by default. HTTP/3 (RFC 9114) runs over IETF QUIC (RFC9000). Default-enabling HTTP/3 in Chrome resulted in improved performance compared not only HTTP/1 and HTTP/2, but also Google QUIC. Benefits included reduced Google search latency and fewer rebuffers for YouTube.

The journey to optimizing performance did not end when HTTP/3 was default enabled. Recent advancements include the implementation of the HTTP/3 ORIGIN frame (RFC 9412) and Server’s Preferred Address (RFC 9000 Section 9.6). The former enhances connection coalescing, while the latter reduces a connection’s round trip time (RTT). Both features have been enabled by default in M131, which was released to Stable on 11/19.

ORIGIN Frame

When a connection is established for a specific hostname, the server’s certificate typically contains numerous other hostnames for which the server is authoritative. However, a client cannot immediately send requests for those other hostnames on that connection without first performing a DNS lookup for the other hostname and verifying that the IP address of the connection matches the resolved address. This additional DNS resolution introduces latency and significantly reduces the likelihood of connection pooling due to potential IP mismatches. The metrics from Chrome indicate that nearly 20% of HTTP/3 connections would be unnecessary if not for this IP mismatch.

Creating a new connection, even with QUIC 0-RTT, is expensive in terms of latency, memory, and CPU usage. This is because:

  • DNS resolution adds latency unless cached locally in Chrome’s DNS cache.
  • Both client and server must send multiple packets to complete a QUIC handshake.
  • TLS necessitates CPU-intensive asymmetric cryptography on both ends.
  • The congestion controller begins in its default state, potentially leading to under or over-sending.
  • 0-RTT might fail.
  • Non-safe requests aren’t sent via 0-RTT.
  • More connections consume more memory.

Additionally, features like HTTP priorities (RFC 9218) are only effective if there are multiple simultaneous responses to send.

The HTTP/3 ORIGIN Frame (RFC 9412) enables a server to indicate what domains it would like to pool onto a connection. Additionally, once the frame is received, it indicates other domains should not be pooled onto that connection, even if they are in the certificate.

Server’s Preferred Address

In some cases, the initial server address to which the client connects is not the most efficient route. It might be behind an L4 load balancer, and connecting directly could increase stability. Particularly when using Anycast, it’s possible the server is distant from where traffic enters the network, creating a 3-legged path that increases the round trip time.

Making Chrome QUICer

Once the handshake is confirmed, Server’s Preferred Address allows a server to indicate it would like the client to migrate to a different server IP. Though a QUIC connection is not bound to a single 4-tuple like TCP, this is the only type of migration in RFC9000 where the server can change its address.

So far, only Google’s Media CDN has widely enabled advertising an alternative address, but we expect more servers to adopt it soon. Testing has shown that this migration is successful over 99% of the time in Chrome and reduces average RTT by 40-80%.

Fedora proposes dropping Atomic desktops for PPC64LE

Posted on December 18, 2024 by Michael G
Fedora is proposing to stop building their Atomic desktop versions for PPC64LE. PopwerPC 64 LE basically comes down to IBM’s POWER architecture, and as far as desktop use goes, that exclusively means the POWER9 machines from Raptor Computing Systems. I reviewed their small single-socket Blackbird machine in 2021, and I also have their dual-socket Talos II workstation. I can tell you from experience that nobody who owns one of these is opting for an immutable Fedora variant, and on top of that, these machines are getting long in the tooth. Raptor passed on POWER10 because it required proprietary firmware, so we’ve been without new machines for years now. As such, it makes sense for Fedora to stop building Atomic desktops for this architecture. We will stop building the Fedora Atomic Desktops for the PowerPC 64 LE architecture. According to the count me statistics, we don’t have any Atomic Desktops users on PPC64LE. Users of Atomic Desktops on PPC64LE will have to either switch back to a Fedora package mode installation or build their own images using Bootable Containers which are available for PPC64LE. ↫ Timothée Ravier I’ve never written much about the Talos II, surmising that most of my Blackbird review applies to the Talos II, as well. If there’s interest, I can check to see what the current state of Fedora and/or other distributions on POWER9 is, and write a short review about the experience. I honestly don’t know if there’s much interest at this point in POWER9, but if there is, here’s your chance to get your questions answered.

Ballistic: Das steckt im neuen Fortnite-Modus

Posted on December 17, 2024 by Michael G
Im Rahmen unseres FYNG-Events 2025 haben wir 30 Minuten den Fortnite-Ballistic-Modus unter die Lupe genommen. Ballistic ist ein taktischer und adrenalingeladener 5v5-Shooter-Modus in Fortnite, der erstmals eine First-Person-Perspektive bietet und auf strategisches Teamplay setzt.

Zum Early Access ist die Karte „Skyline 10“ spielbar, begleitet von einer begrenzten Auswahl an Waffen und Gegenständen. Der Modus kommt ohne das Bauen aus und unterstützt die meisten gespeicherten Looks aus dem Spind, darunter Outfits, Lackierungen und Emotes. Zukünftige Updates bringen basierend auf Spieler-Feedback neue Karten, Waffen und Features.

Schaut euch hier im Video auch unsere Reaktion auf Kapitel 6 – Saison 1 und den OG-Modus an und seht selbst, wie sich unser Paul im Ballistic -Modus schlägt.
