  • Instant messaging service Wire open-sources its server code

    This is a good time for open-source communication systems.

    The decentralized, free software, Twitter-esque social network Mastodon seems to be doing rather well. And now Wire, the end-to-end encrypted instant messaging platform, is releasing the source code for its server.

    The source for the Wire client was already available. But now the company is releasing the server source code, as well—up on GitHub and licensed under the AGPL.

    This is astoundingly good news. As I've written about previously, Wire is a platform I've been quite happy with (I even interviewed the CTO of Wire). One of the downsides? The lack of publicly available source code for the server. That shortcoming is being remedied.

  • Why Slack is inappropriate for open source communications

    My complaint about the growing use of chat services like Slack, HipChat, and so on, for communication by open source projects is that these services are not open. As I see it there are two issues:

    Slack, et al, are paid services with closed memberships. Sure, there are lots of little apps running on Heroku dyno’s that automate the “send me an invite” process, but fundamentally these are closed systems.

    This means that the content inside those systems is closed. I cannot link to a discussion in a Slack channel in a tweet. I cannot refer to it in an issue report, and I cannot cite it in a presentation. Knowledge is silo’d to those who have the time and ability to participate in chat services in real time.
    Slack, et al, are based on synchronous communication, which discriminate against those who do not or can not take part of the conversation in real time. For example, real time chat discriminates against those who aren’t in the same time zone–you can’t participate fully in an open source project if all the discussion happens while you’re asleep.

    Even if you are in the same time zone, real time chat assumes a privilege that you have the spare time–or an employer who doesn’t mind you being constantly distracted–to be virtually present in a chat room. Online chat clients are resource hogs, and presume the availability of a fast computer and ample, always on, internet connection, again raising the bar for participation.

  • What to do when your open source hobby becomes a project

    Many software developers have their own side projects, which are often open source projects. When those open source hobbies grow too big, how do developers manage them?

    All open business and projects face this problem: If they grow too big, more members are necessary for carrying the collective load. Their strategies for scaling are important.

    One popular open source community recently faced this problem. And the way that community surmounted it teaches us something about the art of scaling an open organization.

    The two thousand lines of new code is enough that RadeonSI is working with Linux OpenGL games using bindless textures, like DiRT Rally and other Feral game ports, when paired with RadeonSI Gallium3D patches yet to be posted for review. The ARB_bindless_texture support isn't causing any Piglit regressions issues.

  • How to program games with the LÖVE gaming engine on the Raspberry Pi

    The Raspberry Pi is famous for introducing kids to open source software and programming. The Pi is an affordable, practical introduction to professional-grade computing, disguised as hackable fun. An application that's done the most to get young children started in programming has been Mitch Resnick's Scratch (which fortunately was forked by the Pi Foundation when Scratch 2 switched to the non-open Adobe Air), but an inevitable question is what someone should graduate to after they've outgrown drag-and-drop programming.

    After a drag-and-drop intro like Scratch, there are many candidates for the next level of programming. There's the excellent PyGame, there's a Java subset called Processing, the powerful Godot engine, and many others. The trick is to find a framework that is easy enough to ease the transition from the instant gratification of drag-and-drop, but complex enough to accurately represent what professional programmers actually do all day.

  • Yooka-Laylee released with day-1 Linux support, some quick initial thoughts

    Yooka-Laylee is the 3D platformer throwback to games like Banjo-Kazooie that was funded thanks to Kickstarter back in 2015. It's actually made by some of the original team from game developer Rare, who created some really great games.

    I can confirm that it does seem to work fine on Linux and I haven't encountered any obvious issues so far. I tested it with the Steam Controller with the SC Controller driver/UI and apart from the mouse pointer staying on the screen it felt really great.

  • Adjusting Application Launchers to the Task with KDE Plasma

    The classical desktop, consisting of a menu, panel, and a workspace, has been obsolete for years. What was adequate in the days of twenty megabyte hard drives now leaves users with the choice of either having a workspace inconveniently crowded with launchers, or starting applications entirely from the menu. In answer to this awkward set of choices, KDE’s Plasma offers several alternatives: folder views, filters, and Activities. These alternatives represent different ways of reducing the number of icons on the workspace, so that for any given task, you have only the launchers relevant to what you are currently working on.

Lila-HD icons are designed from scratch for Linux and Unix-like operating systems and licensed under the CREATIVE COMMONS Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0). Basically there are two variants in this set orange which is main and blue which is secondary, you can choose whatever suites your desktop theme. It is well designed and crafted icons theme which gives a glossy look and makes it more appealing but not all icons looks glossy. There are fairly plenty of icons available for applications and contains most of the necessary icons, since this icon theme is in active development so be prepare to see some missing icons or bugs but you can report issues to creator and get them fixed, there is one thing I found need to be added icons for dark panel. It works in most of the Linux desktops such as Unity, KDE, Gnome, Mate, Xfce, Lxde and so. Macbuntu theme used in the following screenshots. You can use Unity Tweak Tool, Gnome-tweak-tool to change themes/icons.

  • Ubuntu Abandoning Unity in Favor of GNOME: What This Means

    On 5 April 2017, Canonical – the UK-based company that develops Ubuntu – has announced its intentions to shift away from the focus of convergence across different platforms in favor of a cloud- and IoT-centric approach. Within that announcement, they have also said something a bit more controversial: they are abandoning the Unity desktop in favor of GNOME for the 18.04 iteration of the Linux distribution.

    For those using other desktop environments like XFCE, LXDE, and MATE, this is basically a “meh” ordeal. The turmoil comes for those who have been bred under the Unity banner, both with and without previous experience using the GNOME environment. What does this mean for Canonical’s long-term strategy, and how does this work for Ubuntu’s comfortable position as one of the most popular Linux distributions?

  • Python vs. Ruby: Which is best for web development?

    Python and Ruby are among some of the most popular programming languages for developing websites, web-based apps, and web services.

    In many ways, the two languages have a lot in common. Visually they are quite similar, and both provide programmers with high-level, object-oriented coding, an interactive shell, standard libraries, and persistence support. However, Python and Ruby are worlds apart in their approach to solving problems because their syntax and philosophies vary greatly, primarily because of their respective histories.

    Which one to implement for web development requires some thought because all languages have strengths and weaknesses and your decision will have consequences.

    The stock kernel of Ubuntu 17.04 is doing away with Direct Rendering Manager (DRM) support for a number of ancient graphics processors.

    A user initially filed a bug report over his VIA S3 UniChrome Pro no longer having DRM support. He commented, "This will make me and other Ubuntu 17.04 users with Via hardware sad (I'm guessing there's at least five of us). Makes for an annoying Ubuntu experience when browsing the web at nearly slide-show speeds while trying to find the correct drivers for our Nvidia and AMD cards."

  • Unraveling the Lamberts Toolkit

    Yesterday, our colleagues from Symantec published their analysis of Longhorn, an advanced threat actor that can be easily compared with Regin, ProjectSauron, Equation or Duqu2 in terms of its complexity.

    Longhorn, which we internally refer to as “The Lamberts”, first came to the attention of the ITSec community in 2014, when our colleagues from FireEye discovered an attack using a zero day vulnerability (CVE-2014-4148). The attack leveraged malware we called ‘BlackLambert’, which was used to target a high profile organization in Europe.

    Since at least 2008, The Lamberts have used multiple sophisticated attack tools against high-profile victims. Their arsenal includes network-driven backdoors, several generations of modular backdoors, harvesting tools, and wipers. Versions for both Windows and OSX are known at this time, with the latest samples created in 2016.

    In my last article, I talked about the classic, complicated approach to server hardening you typically will find in many hardening documents and countered it with some specific, simple hardening steps that are much more effective and take a only few minutes. While discussing how best to harden SSH and sudo can be useful, in a real infrastructure, you also have any number of other services you rely on and also want to harden.

    So instead of choosing specific databases, application servers or web servers, in this follow-up article, I'm going to extend the topic of simple hardening past specific services and talk about more general approaches to hardening that you can apply to software you already have running as well as to your infrastructure as a whole. I start with some general security best practices, then talk about some things to avoid and finally finish up with looking at some areas where sysadmin and security best practices combine.

Hickey today identified two key programs – EXTREMEPARR and EBBISLAND – that can escalate a logged-in user's privileges to root, and obtain root access remotely over the network, on Solaris boxes running versions 6 to 10 on x86 and Sparc, and possibly also the latest build, version 11.

  • Hackers Set Off Dallas' 156 Warning Sirens Dozens Of Times

    So we've talked repeatedly how the shoddy security in most "internet of things" devices has resulted in increasingly-vulnerable home networks, as consumers rush to connect not-so-smart fridges, TVs and tea kettles to the home network. But this failure extends well beyond the home, since these devices have also resulted in historically-large DDoS attacks as this hardware is compromised and integrated into existing botnets (often in just a matter of minutes after being connected to the internet).

    Whether it's the ease in which a decidedly-clumsy ransomware attacker was able to shut down San Francisco's mass transit system, or the fact that many city-connected devices like speed cameras often feature paper mache security, you can start to see why some security experts are worried that there's a dumpster fire brewing that will, sooner rather than later, result in core infrastructure being compromised and, potentially, mass fatalities. If you ask security experts like Bruce Schneier, this isn't a matter of if -- it's a matter of when.
