Go 1.7 is released

TuxMachines - Tue, 2016-08-16 13:22

Today we are happy to announce the release of Go 1.7. You can get it from the download page. There are several significant changes in this release: a port for Linux on IBM z Systems (s390x), compiler improvements, the addition of the context package, and support for hierarchical tests and benchmarks.

A new compiler back end, based on static single-assignment form (SSA), has been under development for the past year. By representing a program in SSA form, a compiler may perform advanced optimizations more easily. This new back end generates more compact, more efficient code that includes optimizations like bounds check elimination and common subexpression elimination. We observed a 5–35% speedup across our benchmarks. For now, the new backend is only available for the 64-bit x86 platform ("amd64"), but we’re planning to convert more architecture backends to SSA in future releases.

GIMP Plugins

Reddit - Tue, 2016-08-16 12:21

I'm trying to make the move to open source and I'd like to show you some useful plugins for GIMP. I think some of these plugins should be part of the software but they are not. So here we go :)

  • LAYER EFFECTS! is something that must exist in GIMP. Maybe they are working on it. It's something I always wanted and it works well with this plugin. I included it first because it's amazing. Here's a screenshot

  • G'MIC is pure beauty. You have all sorts of effects and things to play with, I especially like the film effects (and they are not a few). This plugin is well maintained and everyone of you should try it. The single thing I don't like about it is that image preview feature (the image is a bit too small and you have to enlarge it).

  • I'm not an astrophotographer, I just do visual observations but someone can find these astronomy plugins useful.

  • Beautify has some nice effects. It's basically a mini-editor.

  • Resynthesizer is something I never used but it gets a lot of attention.

  • Save for Web can be useful for people on Reddit :) Posting big images is not a good idea if you have slow internet.

  • Fix-CA for chromatic abberations fixing.

  • Correct lens distortion with GimpLensFun.

  • If you want to paint something with GIMP but want more, try the Paint Studio.

  • If you are using the Infinality font patches, GIMP will render the text with colors at the edges. This will fix it.

  • BIMP for batch image manipulation.

  • Do you want the instagram effects but not the official app? There are some (pretty close) instagram effects for GIMP.

More plugins can be found here. Arch users have better luck, they are basically a few commands away.

I wanted to include the layer effect because that's one of the best plugins right now, I love it. GIMP is not Photoshop, many people should understand that. One is completely free (as in beer and as in freedom) and the other is paid (as in proprietary and as in money).

Happy editing! :)

  • Serving Up Security? Microsoft Patches ‘Malicious Butler’ Exploit — Again

    It’s been a busy year for Windows security. Back in March, Microsoft bulletin MS16-027 addressed a remote code exploit that could grant cybercriminals total control of a PC if users opened “specially crafted media content that is hosted on a website.” Just last month, a problem with secure boot keys caused a minor panic among users.

    However, new Microsoft patches are still dealing with a flaw discovered in November of last year — it was first Evil Maid and now is back again as Malicious Butler. Previous attempts to slam this door shut have been unsuccessful. Has the Redmond giant finally served up software security?

  • PGP Short-ID Collision Attacks Continued, Now Targeted Linus Torvalds

    After contacted the owner, it turned out that one of the keys is a fake. In addition, labelled same names, emails, and even signatures created by more fake keys. Weeks later, more developers found their fake "mirror" keys on the keyserver, including the PGP Global Directory Verification Key.

  • Let's Encrypt: Why create a free, automated, and open CA?

    During the summer of 2012, Eric Rescorla and I decided to start a Certificate Authority (CA). A CA acts as a third-party to issue digital certificates, which certify public keys for certificate holders. The free, automated, and open CA we envisioned, which came to be called Let's Encrypt, has been built and is now one of the larger CAs in the world in terms of issuance volume.

    Starting a new CA is a lot of work—it's not a decision to be made lightly. In this article, I'll explain why we decided to start Let's Encrypt, and why we decided to build a new CA from scratch.

    We had a good reason to start building Let's Encrypt back in 2012. At that time, work on an HTTP/2 specification had started in the Internet Engineering Task Force (IETF), a standards body with a focus on network protocols. The question of whether or not to require encryption (via TLS) for HTTP/2 was hotly debated. My position, shared by my co-workers at Mozilla and many others, was that encryption should be required.

Zenwalk Linux 8.0 - A more Zen Slackware

TuxMachines - Tue, 2016-08-16 12:12

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.

OpenMandriva 3.0, Google Linux Snub, TCP Vulnerability

TuxMachines - Tue, 2016-08-16 12:06

OpenMandriva Lx 3.0 was announced Saturday with Linux 4.6.5, Plasma 5.6.5, and systemd 231. An early reviewer said he liked OpenMandriva but Plasma not as much. Elsewhere all anyone can seem to talk about is Google's decision to use something other than Linux to power its next embedded devices and a TCP vulnerability that could allow remote hijacking of Internet traffic. Patrick Volkerding has upgraded the toolchain in Slackware-current and Red Hat security expert said you can't trust any networks anywhere.

  • Booting Lenovo T460s after Fedora 24 Updates
  • Flock 2016
  • Ideas for getting started in the Linux kernel

    Getting new people into OSS projects is always a challenge. The Linux kernel is no different and has it's own set of challenges. This is a follow up and expansion of some of what I talked about at Flock about contributing to the kernel.

    When I tell people I do kernel work I tend to get a lot of "Wow that's really hard, you must be smart" and "I always wanted to contribute to the kernel but I don't know how to get started". The former thought process tends to lead to the latter, moreso than other projects. I would like to dispel this notion once and for all: you do not have to have a special talent to work on the kernel unless you count dogged persistence and patience as a talent. Working in low level C has its own quriks the same way working in other languages does. C++ templates terrify me, javascript's type system (or lack there of) confuses me. You can learn the skills necessary to work in the kernel.

  • Żegnajcie! Fedora Flock 2016 in words

    From August 2 – 5, the annual Fedora contributor conference, Flock, was held in the beautiful city of Kraków, Poland. Fedora contributors from all over the world attend for a week of talks, workshops, collaboration, fun, and community building (if you’re tuning in and not sure what Fedora is exactly, you can read more here). Talks range from technical topics dealing with upcoming changes to the distribution, talks focusing on the community and things working well and how to improve, and many more. The workshops are a chance for people normally separated by thousands of miles to work and collaborate on real issues, problems, and tasks in the same room. As a Fedora contributor, this is the “premier” event to attend as a community member.

Why Desktop Linux Still Hasn’t Taken Over the World
