Schaller: Looking back at Fedora Workstation so far

Friday 20th of October 2017 08:15:32 PM
Christian Schaller has posted a list of the Fedora Workstation project's accomplishments since its inception. "Wayland – We been the biggest contributor since we joined the effort and have taken the lead on putting in place all the pieces needed for actually using it on a desktop, including starting to ship it as our primary offering in Fedora Workstation 25. This includes putting a lot of effort into ensuring that XWayland works smoothly to ensure full legacy application support." The list as a whole is quite long.

[$] A look at the 4.14 development cycle

Friday 20th of October 2017 07:52:44 PM
The 4.14 kernel, due in the first half of November, is moving into the relatively slow part of the development cycle as of this writing. The time is thus ripe for a look at the changes that went into this kernel cycle and how they got there. While 4.14 is a fairly typical kernel development cycle, there are a couple of aspects that stand out this time around.

Firefox 57 coming soon: a Quantum leap (Fedora Magazine)

Friday 20th of October 2017 01:50:15 PM
The upcoming Firefox 57 release presents a challenge to distributors, who have to decide when and how to ship a major update that will break a bunch of older extensions. This Fedora Magazine article describes the plan that Fedora has come up with for this transition. "Users probably shouldn’t 'hold back at FF56 as my favorite extensions don’t work.' Recall that security fixes only come from new versions, and they’ll all be WebExtension only. The Extended Support Release version will also switch to WebExtensions only at the next release. This date, June 2018, marks the deadline for ESR users to migrate their extensions."

LEDE v17.01.4 service release

Thursday 19th of October 2017 03:43:27 PM
Version 17.01.4 of the LEDE router distribution is available with a number of important fixes. "While this release includes fixes for the bugs in the WPA Protocol disclosed earlier this week, these fixes do not fix the problem on the client-side. You still need to update all your client devices. As some client devices might never receive an update, an optional AP-side workaround was introduced in hostapd to complicate these attacks, slowing them down."

Apache OpenOffice 4.1.4 released

Thursday 19th of October 2017 03:22:51 PM
The OpenOffice 4.1.4 release is finally available; see this article for some background on this release. The announcement is all bright and sunny, but a look at the August 16 Apache board minutes shows concern about the state of the project. Indeed, the OpenOffice project management committee was, according to these minutes, supposed to post an announcement about the state of the project; it would appear that has not yet happened.

Samsung to support Linux distributions on Galaxy handsets

Thursday 19th of October 2017 02:49:17 PM

[$] KRACK, ROCA, and device insecurity

Wednesday 18th of October 2017 10:21:26 PM

Monday October 16 was not a particularly good day for those who are even remotely security conscious—or, in truth, even for those who aren't. Two separate security holes came to light; one probably affects almost all users of modern technology. The other is more esoteric at some level, but still serious. In both cases, the code in question is baked into various devices, which makes it more difficult to fix; in many cases, the devices in question may not even have a plausible path toward a fix. Encryption has been a boon for internet security, but both of these vulnerabilities have highlighted that there is more to security than simply cryptography.

Tips to Secure Your Network in the Wake of KRACK (Linux.com)

Wednesday 18th of October 2017 07:21:31 PM
Konstantin Ryabitsev argues on Linux.com that WiFi security is only a part of the problem. "Wi-Fi is merely the first link in a long chain of communication happening over channels that we should not trust. If I were to guess, the Wi-Fi router you’re using has probably not received a security update since the day it got put together. Worse, it probably came with default or easily guessable administrative credentials that were never changed. Unless you set up and configured that router yourself and you can remember the last time you updated its firmware, you should assume that it is now controlled by someone else and cannot be trusted."

[$] Achieving DisplayPort compliance

Wednesday 18th of October 2017 03:55:40 PM

At the X.Org Developers Conference, hosted by Google in Mountain View, CA September 20-22, Manasi Navare gave a talk about her journey learning about kernel graphics on the way to achieving DisplayPort (DP) compliance for Intel graphics devices. Making that work involved learning about DP, the kernel graphics subsystem, and how to do kernel development, as well. There were plenty of details to absorb, including the relatively new atomic mode setting support, the design of which was described in a two-part LWN article.

Ruiz: Fleet Commander: production ready!

Wednesday 18th of October 2017 03:34:18 PM
Alberto Ruiz announces that Fleet Commander is ready for production use. "Fleet Commander is an integrated solution for large Linux desktop deployments that provides a configuration management interface that is controlled centrally and that covers desktop, applications and network configuration. For people familiar with Group Policy Objects in Active Directory in Windows, it is very similar."

ACME Support in Apache HTTP Server Project

Tuesday 17th of October 2017 06:37:58 PM
Let's Encrypt has announced that Automatic Certificate Management Environment (ACME) protocol support is being integrated into the Apache HTTP Server (httpd). "ACME support being built in to one of the world’s most popular Web servers, Apache httpd, is great because it means that deploying HTTPS will be even easier for millions of websites. It’s a huge step towards delivering the ideal certificate issuance and management experience to as many people as possible."

[$] A comparison of cryptographic keycards

Tuesday 17th of October 2017 03:33:22 PM
An earlier LWN article showed that private key storage is an important problem to solve in any cryptographic system and established keycards as a good way to store private key material offline. But which keycard should we use? This article examines the form factor, openness, and performance of four keycards to try to help readers choose the one that will fit their needs.

Green: Falling through the KRACKs

Tuesday 17th of October 2017 01:19:24 PM
Matthew Green explores the origins of the KRACK vulnerability. "I don’t want to spend much time talking about KRACK itself, because the vulnerability is pretty straightforward. Instead, I want to talk about why this vulnerability continues to exist so many years after WPA was standardized. And separately, to answer a question: how did this attack slip through, despite the fact that the 802.11i handshake was formally proven secure?"

Tried Elementary OS 0.4.1 Loki again - Negatory

The Linux desktop needs a reset. We're now in a post-Ubuntu world, with Unity gone, and we're back in sad and forlorn 2005. There isn't a single major project out there where you can look and say, wow, there's gonna be a fun and exciting year ahead of us. Well, maybe one or two. The rest? Just run-of-the-mill stuff. The forums are quiet, because there isn't anything to report, and rehashing kernel versions and desktop versions isn't really worth anyone's time. I think elementary OS represents this crisis quite well. On its own, it's a badly cobbled release, with too many issues and inconsistencies and a dreadful approach to ergonomics, making it useless to most people, all other things notwithstanding. But it was too buggy for me to even attempt to install it. Not going well. Alas, unless something cardinal changes, I cannot recommend this one at all. The combo of visual glitches, mediocre performance and middling hardware support does not warrant a longer adventure. Perhaps one day this will change, but for now, you're better off with stock Ubuntu. And by that I mean up to Zesty, ad I haven't tried Aardvark yet. Take care, and stay golden.
