Last month in Cambridge was the 2014 GNU Tools Cauldron where GCC as a JIT compiler and other interesting topics were discussed by developers. One of the topics discussed was surrounding better collaboration between GCC and LLVM developers.
While in my earlier 2014 GNU Tools Cauldron coverage I commented on the session about GCC+LLVM collaboration, after the past Phoronix article on the event some additional information was published. The purpose of the GCC and LLVM/Clang compiler teams collaborating is to reach common defaults between compilers, avoid confusion with architecture flags and other compiler switches, and make other improvements to better the interoperability between the compilers to make a better end-user/developer experience. The focus isn't on merging GCC+LLVM, debating licensing differences, fighting over who as the faster compiler, or other such heated topics.
The Unified Extensible Firmware Interface (UEFI) provides boot- and
run-time services for x86 and other computers. For the x86 architecture
it replaces the legacy BIOS. This project will adapt the FreeBSD loader
and kernel boot process for compatibility with UEFI firmware, found on
contemporary servers, desktops, and laptops.
Ed and Nathan completed a number of integration tasks over the past
three months. Nathan added a first-stage loader, boot1.efi, to support
chain-loading the rest of the system from a UFS filesystem. This allows
the UEFI boot process to proceed in a similar fashion as with BIOS
boot. Nathan also added UEFI support to the FreeBSD installer and
release image creation script.
The EFI framebuffer requires the vt(4) system console -- a framebuffer
driver is not implemented for the legacy syscons(4) console. Ed added
automatic vt(4) selection to the UEFI boot path.
Snapshots are now built as dual-mode images, and should boot via both
BIOS and UEFI. Our plan is to merge the UEFI and vt(4) work to
stable/10 to appear in FreeBSD 10.1-RELEASE.
This project is sponsored by The FreeBSD Foundation.
After more than a half-year in development and working on tens of thousands of lines of code, Pkg 1.3.0 has been released by FreeBSD developers.
Pkg 1.3.0 introduces a new solver to automatically handle conflicts and dynamically discover them, pkg install can now install local files and resolve their dependencies via remote repositories, sandboxing of the code has happened, improved portability of the code took place, the pkg API has been simplified, improvements to the multi-repository mode, and a ton of other changes and fixes took place.
More on the pkg 1.3.0 release for improved package management on FreeBSD can be found via this mailing list post.
JabirOS, the distribution formerly powered by Ubuntu that changed to a FreeBSD base and then proclaimed itself an independent FreeBSD fork, is trying to invent its own user-interface.
A Linux kernel developer is working on porting FreeBSD's CAPSICUM security framework over to the Linux kernel.
In announcing his work at the end of June that's now being discussed amongst kernel stakeholders, David Drysdale wrote, "The last couple of versions of FreeBSD (9.x/10.x) have included the Capsicum security framework, which allows security-aware applications to sandbox themselves in a very fine-grained way. For example, OpenSSH now uses Capsicum in its FreeBSD version to restrict sshd's credentials checking process, to reduce the chances of credential leakage. It would be good to have equivalent functionality in Linux, so I've been working on getting the Capsicum framework running in the kernel, and I'd appreciate some feedback/opinions on the general design approach."
We are pleased to announce today, July 4, that the Ubuntu MATE Remix 14.04 has reached Alpha stage and is available for download as Live DVD/USB images that can be installed.
Ubuntu MATE Remix 14.04 Alpha comes as a July 4 surprise to many who believed the controversial project would become reality sooner or later. It beautifully integrates the MATE desktop environment into the latest upstream Ubuntu release.
The distribution was developed by a few members of the Ubuntu community and provides users with an old-school graphical desktop environment, which reminds us of the good ol’ times of Ubuntu 10.04.
