Go Beta, Gogs, GCC Release and TinyCore Linux – Snippets

snippets07
Go 1.3 goes Beta: The first beta of Go 1.3 has been announced. This update will have no language changes, and instead sees improvements to the Go ecosystem like experimental support for Solaris, Plan 9 and, probably most significantly, the return of support for Google’s Native Client (on Intel only for now). The release notes pick out the major goodies – faster builds and binaries thanks to a refactored toolchain and precise garbage collection and a fix to TLS skipping verification – along with the less major changes such as updated Unicode support and tweaks to net/http.

Gogs: Talking about Go, Gogs is an interesting project in its early days, creating a pure Go self-hosted Git service with social account logins, public/private repositories, various database backends and all wrapped up in a single binary which can be built for wherever Go builds. One to keep an eye on.

GCC 4.9.0: Thirteen months since the last major release of the GNU Compiler Collection and version 4.9.0 arrives. Lots of optimiser improvements or existing features being spread to new platforms; for example AddressSanitizer, the memory error detector, is now available on ARM. OpenMP 4.0 is now supported, you can get your C diagnostics in glorious colour, various C11 elements, such as atomics, are now available, improved C++11 support and experimental C++14 support and there’s now Go 1.2.1 support. For all the details, check the changes file.

TinyCore Linux 5.3: Like your Linux tiny? The TinyCore 5.3 has been released with a number of tweaks on the compact Linux which can squeeze into as little as 12MB. Read more at the home page.

Python 3.4 Betas and 3.3.4 RCs, UEFI bootsplaining and Bro pages – Snippets

Python 3.4’s last beta: Over the weekend, the last beta of Python 3.4 arrived. With two more release candidates and a final date of March 16, those interested should be testing now. The time scale was bumped by three weeks to allow last minute changes to the Argument Clinic, a DSL for parsing arguments, to settle in.

What’s also in 3.4? A new pathlib module, standardised enums, better object finalisation semantics, a C API for custom memory allocators, non-inheriting subprocess file descriptors, new statistics, asyncio and tracemalloc modules, a new hash algorithm for strings and binary data and better pickling. And of course, standardised use up “pip” as the package manager.

At this point, 5 Python Enhancement Proposals didn’t make the 3.4 cut – improved time zone database support and zip application support, the locallookup metaclass method, more unpacking generalisations and a key transforming dictionary are all pushed to after 3.4. For more details on whats in and out, check out the release schedule and the download page for 3.4 beta 3.

Python 3.3.4’s RC: There’s also a release candidate now available for Python 3.3.4 – details of fixes in the change log for that. Thats due for a final release on February 9, so not much time for final testing of the large wedge of fixes.

All About UEFI: There’s a lot of controversy, mostly unecessary or ill-informed, about UEFI’s boot process mainly down to it being confused with the optional SecureBoot element of UEFI that Microsoft lean on for validation. Adam Williamson, by day Red Hat Fedora QA, by night massive essay writer, has produced a huge and useful essay on what and how UEFI does its thing and the things it enables called UEFI Boot: How does that actually work then. Well worth a read.

Good idea, bad name: A shortened man page which just gives you examples? Sounds like a great idea. With a central repository for new pages? Excellent. And cross platform and packaged like a ‘gem’? Still with you. And you’re calling them “bro” pages. Oh, ah… this won’t end well. But good idea.
