  • [Slackware] Sep ’16 Security fixes for Adobe Flash
  • Adobe is making a u-turn by resurrecting Flash Player for Linux
  • LibreOffice 5.2.1 for slackware-current

    The upgraded boost package in slackware-current last week had broken LibreOffice’s “localc” program. Which is typical because I compile LibreOffice with a “–without-system-boost” flag. Apparently a dependency on the system’s boost libraries gets added nevertheless. Patches to cure this behaviour are very welcome!

    Thus it became necessary to compile new packages for slackware-current. Co-incidentally there was also a new LibreOffice release last week: a minor upgrade to the 5.2 series, check out the announcement on the Document Foundation blog . And note their designation of this release: “LibreOffice 5.2.1, targeted at technology enthusiasts, early adopters and power users, provides a number of fixes over the major release announced in August. For all other users and enterprise deployments, TDF suggests LibreOffice 5.1.5 “.

Zenwalk Linux 8.0 - A more Zen Slackware

Filed under
Reviews
Slack

There were a few things I enjoyed about Zenwalk 8.0 and several I did not. Before getting to those, I want to acknowledge that Zenwalk is, in most ways, very much like Slackware. The two distributions are binary compatible and if you like (or dislike) one, you will probably feel the same way about the other. They're quite closely related with similar benefits and drawbacks.

On the positive side of things, I like that Zenwalk trims down the software installed by default. A full installation of Zenwalk requires about two-thirds of the disk space a full installation of Slackware consumes. This is reflected in Zenwalk's focused "one-app-per-task" approach which I feel makes it easier to find things. Zenwalk requires relatively little memory (a feature it shares with Slackware) and, with PulseAudio's plugin removed, consumes very few CPU cycles. One more feature I like about this distribution is the fact Zenwalk includes LibreOffice, a feature I missed when running pure Slackware.

On the other hand, I ran into a number of problems with Zenwalk. The dependency problems which annoyed me while running Slackware were present in Zenwalk too. To even get a working text editor I needed to have development libraries installed. To make matters worse, the user needs a text editor to enable the package manager to install development libraries. It's one of those circular problems that require the user to think outside the box (or re-install with all software packages selected).

Other issues I had were more personal. For example, I don't like window transparency or small fonts. These are easy to fix, but it got me off on the wrong foot with Zenwalk. I do want to acknowledge that while my first two days with Zenwalk were mostly spent fixing things, hunting down dependencies and tweaking the desktop to suit my tastes, things got quickly better. By the end of the week I was enjoying Zenwalk's performance, its light nature and its clean menus. I may have had more issues with Zenwalk than Slackware in the first day or so, but by the end of the week I was enjoying using Zenwalk more for my desktop computing.

For people running older computers, I feel it is worth noting Zenwalk does not offer 32-bit builds. The distribution has become 64-bit only and people who still run 32-bit machines will need to turn elsewhere, perhaps to Slackware.

In the end, I feel as though Zenwalk is a more focused flavour of Slackware. The Slackware distribution is multi-purpose, at least as suited for servers as desktops. Slackware runs on more processor architectures, has a live edition and can dump a lot of software on our hard disk. Zenwalk is more desktop focused, with fewer packages and perhaps a nicer selection of applications. The two are quite similar, but Slackware has a broader focus while Zenwalk is geared to desktop users who value performance.

The saga continues with Slackware 14.2

Filed under
Reviews
Slack

Slackware is the oldest surviving Linux distribution and has been maintained since its birth by Patrick Volkerding. Slackware has a well deserved reputation for being stable, consistent and conservative. Slackware is released when it is ready, rather than on a set schedule, and fans of the distribution praise its no-frills and no-fuss design. Slackware adheres to a "keep it simple" philosophy similar to Arch Linux, in that the operating system does not do a lot of hand holding or automatic configuration. The user is expected to know what they are doing and the operating system generally stays out of the way. The latest release of Slackware, version 14.2, mostly offers software updates and accompanying hardware support. A few new features offer improved plug-n-play support for removable devices and this release of Slackware ships with the PulseAudio software. PulseAudio has been commonly found in the audio stack of most Linux distributions for several years, but that is a signature of Slackware: adding new features when they are needed, not when they become available. In this case PulseAudio was required as a dependency for another package.

Slackware 14.2 is available in 32-bit and 64-bit builds for the x86 architecture. There is also an ARM build. While the main edition of Slackware is available as an installation disc only, there is a live edition of Slackware where we can explore a Slackware-powered desktop environment without installing the distribution. The live edition can be found on the Alien Base website. Both the live edition and the main installation media are approximately 2.6GB in size. For the purposes of this review I will be focusing on the main, installation-only edition.

Booting from the install media brings us to a text screen where we are invited to type in any required kernel parameters. We can press the Enter key to take the default settings or wait two minutes for the media to continue booting. A text prompt then offers to let us load an alternative keyboard layout or use the default "US" layout. We are then brought to a text console where a brief blurb offers us tips for setting up disk partitions and swap space. The helpful text says we can create partitions and then run the system installer by typing "setup".

Slackware 14.2

Slackware was familiar. I could easily go back to using it. However, I have been spoiled by my experience with opensuse. With slackware, there are no configured repos. Any install of addition software takes additional effort, though perhaps just unpacking a tar file. And security updates require periodic checking for announcements and then manual installing.

  • Developers: Prepare Your Drivers for Real-Time Linux
    Although Real-Time Linux (RT Linux) has been a staple at Embedded Linux Conferences for years -- here’s a story on the RT presentations in 2007 -- many developers have viewed the technology to be peripheral to their own embedded projects. Yet as RT, enabled via the PREEMPT_RT patch, prepares to be fully integrated into the mainline kernel, a wider circle of developers should pay attention. In particular, Linux device driver authors will need to ensure that their drivers play nice with RT-enabled kernels. At the recent Embedded Linux Conference in Portland, National Instruments software engineer Julia Cartwright, an acting maintainer on a stable release of the RT patch, gave a well-attended presentation called “What Every Driver Developer Should Know about RT.” Cartwright started with an overview of RT, which helps provide guarantees for user task execution for embedded applications that require a high level of determinism. She then described the classes of driver-related problems that can have a detrimental impact to RT, as well as potential resolutions. One of the challenges of any real-time operating system is that most target applications have two types of tasks: those with real-time requirements and latency sensitivity, and those for non-time critical tasks such as disk monitoring, throughput, or I/O. “The two classes of tasks need to run together and maybe communicate with one another with mixed criticality,” explained Cartwright. “You must resolve two different degrees of time sensitivity.” One solution is to split the tasks by using two different hardware platforms. “You could have an Arm Cortex-R, FPGA, or PLD based board for super time-critical stuff, and then a Cortex-A series board with Linux,” said Cartwright. “This offers the best isolation, but it raises the per unit costs, and it’s hard to communicate between the domains.”
  • Clarifying the Linux Real Time Issue
    I recently posted an article about the increasing development and availability of Linux-powered automation devices. This is a clear industry trend that’s unavoidable for anyone following the automation technology industry. Shortly after posting the article, I heard from a reader who wrote: “I read your article and I am surprised that you would promote the idea that anyone would use Linux for anything critical. It isn’t even a real-time control system. It can be used for non-critical applications, but the article implies that industry is adopting it for everything.” This reader brings up a valid point. Linux is not a real-time OS in and of itself. As Vibhoosh Gupta of GE Automation & Controls noted in the original article, GE uses “Type 1 hypervisor technology to run a real-time OS, such as VxWorks, running traditional control loops alongside our PAC Edge technology operating on Linux.” [...] The Linux Foundation launched the RTL (Real Time Linux) Collaborative Project in October 2015. According to the Foundation, the project was “founded by industry experts to advance technologies for the robotics, telecom, manufacturing and medical industries. The aim of the RTL collaborative project is mainlining the PREEMPT_RT patch.” While there are plenty of mission critical applications running Linux OS with real-time extensions—as highlighted by GE, Opto and Wago—the Linux Foundation notes on its site that there remains “much work to be done.”
  • Linux Launches Deep Learning Foundation For Open Source Growth In AI

  • OpenTracing: Distributed Tracing’s Emerging Industry Standard
    What was traditionally known as just Monitoring has clearly been going through a renaissance over the last few years. The industry as a whole is finally moving away from having Monitoring and Logging silos – something we’ve been doing and “preaching” for years – and the term Observability emerged as the new moniker for everything that encompasses any form of infrastructure and application monitoring. Microservices have been around for a over a decade under one name or another. Now often deployed in separate containers it became obvious we need a way to trace transactions through various microservice layers, from the client all the way down to queues, storage, calls to external services, etc. This created a new interest in Transaction Tracing that, although not new, has now re-emerged as the third pillar of observability.

  • Hackers Leaked The Code Of iPhone Cracking Device “GrayKey”, Attempted Extortion
    The mysterious piece of hardware GrayKey might give a sense of happiness to cops because they can get inside most of the iPhone models currently active, including the iPhone X. The $30,000 device is known to crack a 4-digit iPhone passcode in a matter of a few hours, and a six-digit passcode in 3 days, or possibly 11 hours in ideal scenarios. That’s why security experts suggest that iOS users should keep an alphanumeric passcode instead of an all-number passcode.
  • Someone Is Trying to Extort iPhone Crackers GrayShift With Leaked Code
    Law enforcement agencies across the country are buying or have expressed interest in buying GrayKey, a device that can unlock up-to-date iPhones. But Grayshift, the company that makes the device, has attracted some other attention as well. Last week, an unknown party quietly leaked portions of GrayKey code onto the internet, and demanded over $15,000 from Grayshift—ironically, the price of an entry-level GrayKey—in order to stop publishing the material. The code itself does not appear to be particularly sensitive, but Grayshift confirmed to Motherboard the brief data leak that led to the extortion attempt.

The Chocolate Factory on Monday told The Register that someone has indeed created and sent spam with forged email headers. These not only override the send address, so that it appears a legit Gmail user sent the message, but it also mysteriously shows up in that person's sent box as if they had typed it and emitted themselves. In turn, the messages would also appear in their inboxes as sent mail.

It is written in Go programming language and works in the same way as curl but only aims to offer common usage options and procedures, with emphasis on the HTTP(S) operations. In this tutorial we will learn how to install and use kurly program – an alternative to most widely used curl command in Linux.
  • Pamac – Easily Install and Manage Software on Arch Linux
    Arch Linux is one of the most popular Linux distribution available despite its apparent technicality. Its default package manager pacman is powerful but as time always tells, it is a lot easier to get certain things done using a mouse because GUI apps barely require any typing nor do they require you to remember any commands; and this is where Pamac comes in. Pamac is a Gtk3 frontend for libalpm and it is the GUI tool that Arch Linux users turn to the most when they aren’t in the mood to manage their software packages via the terminal; and who can blame them? It was specifically created to be used with Pacman.
