  • BadTunnel: Critical vulnerability affects every version of Microsoft's OS since Windows 95

    A security researcher from Tencent, China's largest internet service portal, has discovered a critical security flaw in Microsoft's Windows operating system that affects every single version of Windows over the last two decades, from Windows 95 all the way to Windows 10.

  • Decentralized Security

    If you're a fan of the cryptocurrency projects, you've heard of something called Ethereum. It's similar to bitcoin, but is a seperate coin. It's been in the news lately due to an attack on the currency. Nobody is sure how this story will end at this point, there are a few possible options, none are good. This got me thinking about the future of security, there are some parallels when you compare traditional currency to crypto currency as well as where we see security heading (stick with me here).

    The current way currency works is there is some central organization that is responsible for minting and controlling the currency, usually a country. There are banks, exchanges, loans, interest, physical money, and countless other ways the currency interacts with society. We will compare this to how IT security has mostly worked in the past. You had one large organization responsible for everything. If something went wrong, you could rely on the owner to take control and make things better. There are some instances where this isn't true, but in general it holds.

    Now if we look at cryptocurrency, there isn't really a single group or person in charge. That's the whole point though. The idea is to have nobody in charge so the currency can be used with some level of anonymity. You don't have to rely on some sort of central organization to give the currency legitimacy, the system itself has legitimacy built in.

  • GTK Hackfest 2016

    I'm back from the GTK hackfest in Toronto, Canada and mostly recovered from jetlag, so it's time to write up my notes on what we discussed there.

    Despite the hackfest's title, I was mainly there to talk about non-GUI parts of the stack, and technologies that fit more closely in what could be seen as the freedesktop.org platform than they do in GNOME. In particular, I'm interested in Flatpak as a way to deploy self-contained "apps" in a freedesktop-based, sandboxed runtime environment layered over the Universal Operating System and its many derivatives, with both binary and source compatibility with other GNU/Linux distributions.s

  • Scenario tasks

    In the upcoming weeks you will be able to see these tips “in action” since we will create more scenario tasks for GNOME applications.

  • Wrapping up scenario tasks

    And scenario tasks need to be written using the language that your testers would normally use. Avoid using very technical words if your users wouldn't be technical. You might use technical words and phrases if you were building a usability test for a programmer's IDE and Debugger, but you wouldn't use technical words and phrases for a general desktop environment like GNOME. It's all about finding the right balance and "voice" in your scenario tasks.

  • Maple syrup

    Last week I attended the GTK+ hackfest in Toronto. We had a really good group of people for the event, which lasted 4 days in total, and felt really productive.

    There were a number of interesting discussion and planning sessions, from a design point of view, including a session on Flatpak “portals” and another on responsive design patterns.

KDE Neon: The Rock & Roll Distribution

Filed under
KDE

What does it mean when developers behind one of the world's most popular desktop environments decide to jump into the deep end and fork a distribution? Depending on who you ask you’ll hear madness, excellence, confusion, and excitement as onlookers figure out the exact nature of a new breed of beast and guess what it will do.

KDE neon is a new distribution freshly forked from Ubuntu being driven by prominent KDE contributors and figures. When initially announced some mixed messages marred the event, but since then the project has found its footing and expectations are seemingly being set...

Neon is entirely unique as a product produced by a community which always made generalist software; Plasma and KDE software is offered by Suse, Red Hat, Arch, Slack, any distribution you can name. Neon is in direct competition with those systems, and several people decried this new distribution as opening the potential for favouritism.

LibreOffice Getting Automatic Crash Reporting

Markus Mohrhard cross-posted today on the Document Foundation blog of a new feature coming in LibreOffice 5.2. Mohrhard said, "Starting with LibreOffice 5.2 the LibreOffice project will have an automated crash reporting tool with server side analysis." In other news, GNOME's Sébastien Wilmet today blogged this thoughts on Mint's X-Apps, little applications commonly forked from GNOME apps and Sam Varghese reported on the exit of Jacob Appelbaum from Debian. Gizmodo listed five reasons to install Linux, and by Linux they mean Ubuntu, onto your laptop and Matt Hartley discussed why Ubuntu LTS is better than the latest and greatest.

4 fun (and semi-useless) Linux toys

Filed under
OSS

There's so many more fun projects out there to explore, so don't let my modest list be the end of the adventure. Too often in the open source world, we suffer from people looking in, scrutinizing what we make, and seeking practical and clear paths toward monetization. But that's not what open source is about, really; open source is supposed to be fun and inspiring. It empowers everyone to follow their vaguest notion to completion, no matter how "useless" or "frivolous" it may be.

Exploiting Recursion in the Linux Kernel

Filed under
Linux

On Linux, userland processes typically have a stack that is around 8 MB long. If a program overflows the stack, e.g. using infinite recursion, this is normally caught by a guard page below the stack.

Linux kernel stacks, which are e.g. used when handling system calls, are very different. They are relatively short: 4096 bytes on 32-bit x86, 16384 bytes on x86-64. (The kernel stack size is specified by THREAD_SIZE_ORDER and THREAD_SIZE.) They are allocated using the kernel's buddy allocator, which is the kernel's normal allocator for page-sized allocations (and power-of-two numbers of pages) and doesn't create guard pages. This means that if kernel stacks overflow, they overlap with normal data. For this reason, kernel code must be (and usually is) very careful to not make big allocations on the stack and has to prevent excessive recursion.

Secure home automation, without clouds or dedicated hubs

Filed under
OSS

Several home automation platforms support Python as an extension, but if you’re a real Python fiend, you’ll probably want Home Assistant, which places the programming language front and center. Paulus Schoutsen created Home Assistant in 2013 “as a simple script to turn on the lights when the sun was setting,” as he told attendees of his recent Embedded Linux Conference and OpenIoT Summit presentation, “Automating your Home with Home Assistant: Python’s Answer to the Internet of Things.”

Schoutsen, who works as a senior software engineer for AppFolio in San Diego, has attracted 20 active contributors to the project. Home Assistant is now fairly mature, with updates every two weeks and support for more than 240 different smart devices and services. The open source (MIT license) software runs on anything that can run Python 3 — from desktop PCs to a Raspberry Pi, and counts thousands of users around the world.

Is Android on Chromebook ready for mainstream use? Not quite yet. But, I can see it from where it is now. I've long thought that Chromebooks could replace Windows PCs. Now, with Android apps, I can see people choosing $200 Chromebooks over $400 Windows 10 laptops. Windows' last stronghold, the desktop, finally has some real competition.

Huawei CEO: Will keep using Android as long as it's open

He made the said comment in a Weibo post, where-in he also noted that Google's mobile OS has promoted the development of smartphones, which in turn has benefited consumers. Interestingly, he didn't say anything about whether or not Huawei is developing an in-house mobile OS - said to be called Kirin OS. His silence on the matter, though, can be taken as a confirmation of sorts, especially when his comment reflects the possibility of Google restricting the companies’ freedom with Android in future.
