Call for testing: OpenSSH 10.0 (DSA support removed)
(mindrot.org)
Hi all. OpenSSH 10.0p1 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This is primarily a bugfix release, although one notable change is the introduction of the sshd-auth binary (see below).

The Nvidia DGX Spark Is a Tiny 128GB AI Mini PC Made for Scale-Out Clustering
(servethehome.com)
With 20 Arm cores connected using C2C to a Blackwell generation GPU, 128GB of LPDDR5X memory, and 200GbE NVIDIA ConnectX-7 networking, the NVIDIA DGX Spark is exciting. At $3999 it is far from cheap. On the other hand, we expect folks to create the most awesome clusters with this.

HTTP/3 and the QUIC Internet Protocol
(themsaid.com)
In a previous article, we delved into the TCP/IP networking model. As the article concluded, we examined the significant advancements introduced by HTTP/2, particularly its ability to multiplex multiple requests over a single TCP connection. This approach not only enhanced efficiency but also addressed many of the limitations found in earlier protocols.

IO_uring Network Zero-Copy Receive Lands in Linux 6.15
(phoronix.com)
IO_uring continues maturing while being one of the greatest innovations within the Linux kernel in the past number of years. With Linux 6.15, IO_uring is getting even more interesting with introducing network zero-copy receive support. With this new code a 200G link could be saturated off a single CPU core in a recent demonstration.

Through Project SERVFAIL, I became aware that there are a few individuals, not just ISPs, who host their own in-addr.arpa. and ip6.arpa. zones. It never occurred to me that I could ask bgp.wtf, my beloved ISP, to delegate me a zone like this - until one faithful late-night chat.ARPA zones are usually totally out of reach for individuals, so I was absolutely hyped when one of our netadmins agreed to delegate me the ip6.arpa. zone for my whole /48 IPv6 range.

HTTP/2 zero latency write coalescing
(nitely.github.io)
Write coalescing is an I/O optimization technique where multiple small writes are merged into a single larger write before sending data to the underlying system. In Http/2, we can batch multiple frames from one or more streams and send them all at once. This reduces the number of syscalls, and avoids sending tiny TCP packets under load.
