Huawei announces tiny 10 KB IoT kernel

Huawei has offered up a good look at its Internet of Things strategy, using its Network Congress 2015 to show off a microkernel that will be the bedrock of its future efforts in the field.

Linux kernel devs adopt Bill and Ted's excellent code of conduct

The Linux kernel development community and its leader Linus Torvalds are both famously feisty: strong words are often exchanged on the Linux Kernel Mailing List, while Linux Lord Linus Torvalds is seldom shy of speaking his mind. Of late, however, Torvalds has copped some criticism for being a little too strident, perhaps …

Leaked screenshots show next Windows kernel to be a perfect 10

Microsoft surprised us by upping its Windows product numbering from 8.1 straight to 10, and now it appears it's planning to make an even greater leap in the version numbering of the Windows kernel itself.

Loved-up 'frictionless' EMC bods slide ScaleIO into VMware kernel

EMC is going to extend its ScaleIO serverSAN product to function as a VMware kernel module to speed it up, thereby "twinning" it with VSAN in terms of VMware and ESXi integration.

Linux distros fix kernel terminal root-hole bug

Linux admins need to get busy patching, as a newly discovered bug has emerged in the kernel's tty handling – and it lets logged-in users crash the system, gain root privileges, or otherwise modify and access data they shouldn't.
