WordPress 4.7

Tuesday 6th of December 2016 09:06:34 PM
WordPress 4.7 “Vaughan” has been released. This version includes a new default theme, adds new features to the customizer, comes with REST API endpoints for posts, comments, terms, users, meta, and settings, and more. "To help give you a solid base to build from, individual themes can provide starter content that appears when you go to customize your brand new site. This can range from placing a business information widget in the best location to providing a sample menu with social icon links to a static front page complete with beautiful images. Don’t worry – nothing new will appear on the live site until you’re ready to save and publish your initial theme setup."

[$] Maintainerless Debian?

Tuesday 6th of December 2016 05:51:02 PM
The maintainer model is deeply ingrained into the culture of the free-software community; for any bit of code, there is usually a developer (or a small group of developers) charged with that code's maintenance. Good maintainers can help a project run smoothly, while poor maintainers can run things into the ground. What is to be done to save a project with the latter type of maintainer? Forking can be an option in some cases but, in many others, it's not a practical alternative. The Debian project is currently discussing its approach to bad maintainers — a discussion which has taken a surprising turn.

Bottomley: Using Your TPM as a Secure Key Store

Monday 5th of December 2016 09:03:26 PM
James Bottomley has posted a tutorial on using the trusted platform module to store cryptographic keys. "The main thing that came out of this discussion was that a lot of this stack complexity can be hidden from users and we should concentrate on making the TPM 'just work' for all cryptographic functions where we have parallels in the existing security layers (like the keystore). One of the great advantages of the TPM, instead of messing about with USB pkcs11 tokens, is that it has a file format for TPM keys (I’ll explain this later) which can be used directly in place of standard private key files."

Kernel prepatch 4.9-rc8

Monday 5th of December 2016 12:48:26 PM
The 4.9-rc8 kernel prepatch is out; the final 4.9 release will need one more week. "So if anybody has been following the git tree, it should come as no surprise that I ended up doing an rc8 after all: things haven't been bad, but it also hasn't been the complete quiet that would have made me go 'no point in doing another week'."

What's new in OpenStack in 2016: A look at the Newton release (

Friday 2nd of December 2016 09:13:37 PM
Over at, Rich Bowen gives an overview of the changes in the OpenStack Newton release that was made in October. In it, he looks at each of sub-projects and highlights some of the changes for them that were in the release, which is also useful as a kind high-level guide to some of the various sub-projects and their roles. "With a product as large as OpenStack, summarizing what's new in a particular release is challenging. (See the full release notes for more details.) Each deployment of OpenStack might use a different combination of services and projects, and so will care about different updates. Added to that, the release notes for the various projects tend to be extremely technical in nature, and often don't do a great job of calling out the changes that will actually be noticed by either operators or users."

BitUnmap: Attacking Android Ashmem (Project Zero blog)

Friday 2nd of December 2016 08:24:23 PM
Google's Project Zero blog has a detailed look at exploiting a vulnerability in Android's ashmem shared-memory facility. "The mismatch between the mmap-ed and munmap-ed length provides us with a great exploitation primitive! Specifically, we could supply a short length for the mmap operation and a longer length for the munmap operation - thus resulting in deletion of an arbitrarily large range of virtual memory following our bitmap object. Moreover, there’s no need for the deleted range to contain one continuous memory mapping, since the range supplied in munmap simply ignores unmapped pages. Once we delete a range of memory, we can then attempt to “re-capture” that memory region with controlled data, by causing another allocation in the remote process. By doing so, we can forcibly “free” a data structure and replace its contents with our own chosen data -- effectively forcing a use-after-free condition."

Trouble at Cyanogen

Thursday 1st of December 2016 03:50:59 PM
Cyanogen Inc. has put out a terse press release announcing the departure of founder (and CyanogenMod creator) Steve Kondik. See this rather less terse Android Police article for Kondik's view of the matter. The future of the CyanogenMod distribution seems unclear at this point; if it goes forward, it may have to do so with a different name.

Wednesday 30th of November 2016 04:17:13 PM
As covered here in January, changes to the GNU C Library's memory-allocation routines have broken the "unexec" method used to build the Emacs editor. Fixing this problem has proved to be more challenging than originally thought; that issue has now come to a head in a disagreement that could cost the Emacs community one of its maintainers.

Time is running out for NTP (InfoWorld)

Monday 28th of November 2016 10:44:39 PM
InfoWorld looks at the underfunded NTP project. "NTP is more than 30 years old—it may be the oldest codebase running on the internet. Despite some hiccups, it continues to work well. But the project’s future is uncertain because the number of volunteer contributors has shrunk, and there’s too much work for one person—principal maintainer Harlan Stenn—to handle. When there is limited support, the project has to pick and choose what tasks it can afford to complete, which slows down maintenance and stifles innovation."

Doyodo RetroEngine Sigma is a Linux-powered classic video game emulation console

The Nintendo NES Classic is quite an amazing console. True, it is not as powerful as modern game systems like Xbox One and PlayStation 4, but it comes pre-loaded with many classic NES titles. Unfortunately, its strength is also its weakness -- those pre-loaded titles are the only games you can play. You cannot load other games, so you are stuck with what you got. Read more
