Linux Kernel Gets More Infrastructure for Rust, Increasing Interest in the Language

Linux 6.1 (released last month) included what Linus Torvalds described as “initial Rust scaffolding,” remembers this update from SD Times But now, “work has already been done since the 6.1 release to add more infrastructure for Rust in the kernel, though still none of the code interacts with any C code.”

And there’s still no actual Rust code in Linux:

“You need to get all those things that can make sure that Rust can compile, and you can do the debugging and all these things,” explained Joel Marcey, director of advocacy and operations for the Rust Foundation, “and make sure that the memory safety is there and all that sort of stuff. And that has to happen first before you can actually write any real code in Rust for the Linux kernel itself.”

Marcey explained that Linux is going to be doing this inclusion very piecemeal, with lots of little integrations here and there over time so they can see how it is working. “I would imagine that over the next year, you’re going to see more small incremental changes to the kernel with Rust, but as people are seeing that it’s actually kind of working out, you’ll be able to maybe, for example, write Linux drivers or whatever with Rust,” said Marcey….

According to Bec Rumbul, executive director of the Rust Foundation, Rust being added to the kernel is an “enormous vote of confidence in the Rust programming language.” She explained that in the past other languages have been planned to make it into the kernel and ended up not getting put in. “I think having someone with the kind of intellectual gravity of Linus Torvalds saying ‘No, it’s going in there,’ that kind of says an awful lot about how reliable Rust already is and how much potential there is for the future as well,” she said.

Rumbul believes that there will be an increased interest in the language, which is still relatively new (It first made its debut in 2010) compared to some of the other languages out there to choose from. “I suspect that because Rust is now in the kernel, and it’s just being talked about much … more widely, that it will seem like an attractive prospect to a lot of people that are looking to develop their skills and their knowledge,” she said. Rumbul hopes people will also be inspired to participate in the language as contributors and maintainers, because those are some of the less popular roles within open source, but are extremely critical to the health of a language, she explained.
The Rust Foundation also launched a new security team in September to ensure best practices (including a dedicated security engineer). Their first initiative will be a security audit and threat modeling exercises.

“We want to basically shore up,” Rust operations director Marcey tells SD Times, “to ensure that Rust itself is actually as secure as we always say it is.”

In this year’s Stack Overflow Developer Survey, 86.73% of developers said they love Rust.

Intel Officially Introduces Pay-As-You-Go Chip Licensing

Intel has officially revealed its Intel On Demand program that will activate select accelerators and features of the company’s upcoming Xeon Scalable Sapphire Rapids processor. The new pay-as-you-go program will allow Intel to reduce the number of SKUs it ships while still capitalizing on the technologies it has to offer. From a report: Furthermore, its clients will be able to upgrade their machines without replacing actual hardware or offering additional services to their clients. Intel’s upcoming Intel’s 4th Generation Xeon Scalable Sapphire Rapids processors are equipped with various special-purpose accelerators and security technologies that all customers do not need at all times. To offer such end-users additional flexibility regarding investments, Intel will deliver them to buy its CPUs with those capabilities disabled but turn them on if they are needed at some point. The Software Defined Silicon (SDSi) technology will also allow Intel to sell fewer CPU models and then enable its clients or partners to activate certain features if needed (to use them on-prem or offer them as a service). The list of technologies that Intel wants to make available on demand includes Software Guard Extensions, Dynamic Load Balancer (DLB), Intel Data Streaming Accelerator (DSA), Intel In-Memory Analytics Accelerator (IAA), Intel In-Memory Analytics Accelerator, and Intel QuickAssist Technology (QAT) to accelerate specific workloads.

FDA Approves Most Expensive Drug Ever, a $3.5 Million-per-Dose Gene Therapy For Hemophilia B

U.S. health regulators this week approved the first gene therapy for hemophilia, a $3.5 million one-time treatment for the blood-clotting disorder. From a report: The Food and Drug Administration cleared Hemgenix, an IV treatment for adults with hemophilia B, the less common form of the genetic disorder which primarily affects men. Currently, patients receive frequent, expensive IVs of a protein that helps blood clot and prevent bleeding. Drugmaker CSL Behring, based in Pennsylvania, announced the $3.5 million price tag shortly after the FDA approval, saying its drug would ultimately reduce health care costs because patients would have fewer bleeding incidents and need fewer clotting treatments.

According to a study cited by the National Library of Medicine, the price makes Hemgenix the most expensive medicine in the world, easily topping Novartis’ Zolgensma gene therapy for spinal muscular atrophy (SMA), which costs right around $2 million per dose and is also a single-dose medicine. Like most medicines in the U.S., most of the cost of the new treatment will be paid by insurers, not patients, including private plans and government programs. After decades of research, gene therapies have begun reshaping the treatment of cancers and rare inheritable diseases with medicines that can modify or correct mutations embedded in people’s genetic code. Hemgenix is the first such treatment for hemophilia and several other drugmakers are working on gene therapies for the more common form of the disorder, hemophilia A.
