Kali Linux Roadmap (2019/2020)

Filed under
GNU
Linux

Now that our 2019.2 release is out, we thought we would take this opportunity to cover some of the changes and new features we have coming to Kali Linux in the following year. Normally, we only really announce things when they are ready to go public, but a number of these changes are going to impact users pretty extensively so we wanted to share them early.

As you read through this post, what you will see is that we are really trying to balance our efforts between changes that are user facing and those that are applicable to the backend. The backend changes don’t seem as exciting at first, but the fact is that the easier it is for us to work on Kali, the easier it is for us to get to user facing features. Plus, some of these changes are focused on tweaking the development process to make it easier for others to get involved in the project.

We are not ready to announce dates on any of these changes just yet. When they are ready, they will drop.

Infographic: Linux Mint Challenges Windows 10 In Small Business Productivity Speed Tests

Filed under
GNU
Linux

Linux is typically less resource-hungry than Microsoft's Windows 10, and that gives it a distinct advantage on under-powered desktops and laptops. Linux is constantly celebrated for reviving older hardware (think low-powered Atom processors and a scant 1GB or 2GB of RAM) that struggles to run smoothly under Windows. It's an advantage I haven't (yet) had the opportunity to test in the real world, though. Thankfully, community member James Dawson who owns and operates Melbournes's DXM Tech Support did some testing and published a fantastic infographic illustrating the speeds of various productivity and business tasks using a "cheap and cheerful" HP laptop.

All Linux, all the time: Supercomputers Top 500

Filed under
GNU
Linux
Server

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux.

Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight.

When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores.

And, what do all these processors run? Linux, of course.
.
133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed.

Spanish Linux computer company Slimbook has unveiled its brand new all-in-one “Apollo” Linux PC — and it looks… Well, it looks familiar.

The Apollo AIO swaps the curved screen of its immediate predecessor for a 23.6-inch IPS LED display running at a decent 1920×1080 resolution. The screen is apparently a “crystal coated panel” that improves the appearance of colours.

Internally, the AIO is configurable according to needs. There’s a choice of Intel i5-8500 and Intel i7-8700 processor, up to 32GB RAM, integrated Intel UHD 630 4K graphics, and a veritable smorgasbord of storage options.

Software

Mind maps are diagrams used to organize information visually in hierarchical ways that show relationships among the elements that make up the map. Drawing mind maps have been proven to be highly effective for getting information in and out of the brain especially when combined with logical note-taking that typically details or summarizes the roles of the map’s components along the way.

There are various mind mapping software out there ranging from free to paid to open source options. Today, my job is to list the best mind mapping software available to users for free. They are all modern, easy enough to use, and offer sufficient consumer support.

I bought a hack computer for $299 - it's designed for teaching 8+ year olds programming. That's not my intended use case, but I wanted to support a Linux pre-installed vendor with my purchase (I bought an OLPC back in the day in the buy-one give-one program).

I only use a laptop for company events, which are usually 2-4 weeks a year. Otherwise, I use my desktop. I would have bought a machine with Ubuntu pre-installed if I was looking for more of a daily driver.

Dell may be the best-known Linux laptop vendor right now, but Lenovo is looking to muscle in on the pre-installed Linux machine market.

All of Lenovo’s refreshed ThinkPad P series laptops will be available to buy with Ubuntu 18.04 LTS preinstalled when they go on sale in the US later this month.

Oddly, Lenovo doesn’t mention Linux availability in their press release introducing the new ThinkPad P series laptops, but eagle-eyed Linux users spotted the additional OS option on when investigating the laptop’s ‘tech specs’ on the Lenovo website.

The company says its refreshed P-series ‘portfolio’ is “…is designed to meet the ever-changing power and portability needs of modern professionals across industries – both in the office and beyond without sacrificing our legendary engineering know-how, reliability and security.”

  • SUSE on the IO500 List for HPC Storage
    If you haven’t been hanging around the Ceph world for a bit, you may not realize that Ceph was originally intended to provide a distributed file-system to service HPC clusters.  While this was the original intent, Ceph has taken a round-a-bout path to relevance in this space, especially given that we are only supporting multiple active MDS servers since the Luminous release.  The result is that we are, only now, really starting to see adoption in the HPC space, and mostly for the second tier storage needs. Enter, the science project.  Given an all-flash environment on SATA SSDS with a fast storage pool on Intel Optane for the metadata, would it be possible to provide a reasonable storage environment for HPC clusters?

  • Daniel Stenberg: Google to reimplement curl in libcrurl
    By throwing a lot of man power on it. As the primary author and developer of the libcurl API and the libcurl code, I assume that Cronet works quite differently than libcurl so there’s going to be quite a lot of wrestling of data and code flow to make this API work on that code. The libcurl API is also very versatile and is an API that has developed over a period of almost 20 years so there’s a lot of functionality, a lot of options and a lot of subtle behavior that may or may not be easy or straight forward to mimic. The initial commit imported the headers and examples from the curl 7.65.1 release.
  • Microsoft, you should look away now: Google's cloud second only to AWS in dev survey [Ed: Longtime Microsoft booster Tim Anderson  on Azure being a failure after so many entryism attempts and underhanded tactics]
    Coders use Google Cloud Platform (GCP) more than Microsoft Azure, though Amazon Web Services (AWS) has a comfortable lead, according to a Developer Ecosystem survey conducted by tools vendor JetBrains. Developer usage is 67 per cent AWS versus 28 per cent GCP and 21 per cent Azure, according to the new survey. Unfortunately, the question was posed in a different way in the 2018 survey, adding on-premises into the mix, but last year Azure and GCP had equal share after AWS. The survey had 19,000 participants invited via "Twitter ads, Facebook ads, Google Adwords and JetBrains' own communication channels," the tools vendor said, though "only the responses of 6,993 respondents were included in the report." Responses were removed to reduce bias, yet it warned "some bias may be present as JetBrains users may have been more willing on average to compete the survey".

Kernel: Linux Changes, Certifications, Graphics, PCI Express 6.0 and Bug

  • PowerCap/RAPL Code To Support Icelake Desktop / X / Xeon D With Linux 5.3
    While as of Linux 5.2 the support for Intel's Icelake CPUs appear production ready with all of the bits in place from new IDs to the much enhanced "Gen 11" graphics, there are a few stragglers of items to land with the upcoming Linux 5.3 merge window though could be back-ported to current series. Fortunately, we haven't found anything major to be missing. One of the latest bits of Icelake Linux support is handling of these next-generation processors within the PowerCap / RAPL (Running Average Power Limit) driver code. In particular, the desktop/workstation Icelake parts. This is the code for reading the estimated CPU package power consumption based on hardware performance counters and the ability to artificially limit the power draw of the processor via software.

  • AMD Navi GPU stack bares all in Linux graphics driver update
    Eight Navi GPU variants have been spotted in Linux driver code. AMD’s next-gen RDNA graphics chips are set for launch on July 7, 2019 within the RX 5700 XT and RX 5700, but the red team has plenty of silicon in store for a range of applications. Including console, laptops, desktop, and mobile phones. The GPU codenames were spotted within Linux display drivers after the additional code was submitted and signed off by two AMD employees. The code adds support for Display Core Next, or DCN2, which “is the display block for Navi10.” Each entry following adds the necessary ASIC IDs for each Navi chip in the stack, starting with Navi 10 and down to Navi 21 LITE.
