GNU lightning 2.1.3 released!

Filed under
GNU

GNU lightning is a library to aid in making portable programs 
that compile assembly code at run time. 
Development: 
http://git.savannah.gnu.org/cgit/lightning.git 
Download release: 
ftp://ftp.gnu.org/gnu/lightning/lightning-2.1.3.tar.gz 
  2.1.3 main features are the new RISC-V port, currently supporting 
only Linux 64 bit, and a major rewrite of the register live and 
unknown state logic, so that a long standing issue with a live 
register not accessed for several consecutive blocks could be 
incorrectly assumed dead. 
The matrix of built and tested environments is:

  • Python alternative to Docker

    Deploying a Python app to a server is surprisingly hard. Without blinking, you’ll be dealing with virtual environments and a host of other complications.

    The landscape of deployment methods is huge. What if I told you that there is a way to build your app into a single file and it isn’t a Docker container?

    In this article, we’re going to look at common ways of deploying Python apps. We’ll explore the touted benefits of Docker containers to understand why containers are so popular for web apps. Finally, we’ll look at an alternative to Docker that may be a lot simpler for your Python web app and compare and contrast this alternative against Docker.

  • How to Convert a Python String to int

    Integers are whole numbers. In other words, they have no fractional component. Two data types you can use to store an integer in Python are int and str. These types offer flexibility for working with integers in different circumstances. In this tutorial, you’ll learn how you can convert a Python string to an int. You’ll also learn how to convert an int to a string.

  • Free Coaching For PyGotham Speakers

    I help organize PyGotham, NYC’s annual conference about the Python programming language.

  • 8 Excellent C++ Natural Language Processing Tools

    Natural language processing (NLP) is a set of techniques for using computers to detect in human language the kinds of things that humans detect automatically.

    Natural language processing (NLP) is an exciting field of computer science, artificial intelligence, and computational linguistics concerned with the interactions between computers and human (natural) languages. It includes word and sentence tokenization, text classification and sentiment analysis, spelling correction, information extraction, parsing, meaning extraction, and question answering.

Debian May Need To Re-Evaluate Its Interest In "Init System Diversity"

Filed under
Debian

Debian Project Leader Sam Hartman has shared his August 2019 notes where he outlines the frustrations and issues that have come up as a result of init system diversity with some developers still aiming to viably support systemd alternatives within Debian.

Stemming from elogind being blocked from transitioning to testing and the lack of clarity into that, Hartman was pulled in to try to help mediate the matter and get to the bottom of the situation with a lack of cooperation between the elogind and systemd maintainers for Debian as well as the release team. Elogind is used by some distributions as an implementation of systemd's logind, well, outside of systemd as a standalone daemon. Elogind is one of the pieces to the puzzle for trying to maintain a modern, systemd-free Linux distribution.

Linux 5.4 Developments and Merges

Filed under
Linux
  • Linux 5.4 Power Management Updates Sent In But Without AMD CPPC Changes

    The Linux 5.4 power management changes have been submitted for this next version of the Linux kernel.

    This time around the power management work isn't particularly exciting with no breakthroughs for the Intel P-State driver, no major changes to the other prominent CPUFreq drivers/governors, and no AMD CPPC support for their new processors.

  • Linux 5.4 Preps For Intel Tiger Lake, Elkhart Lake & Lightning Mountain + Killing MPX

    The Linux 5.4 x86/cpu changes are as busy as always on the Intel side.

    The Linux 5.4 x86/cpu code changes include cleaning up the Intel CPU naming conventions within definitions in the code. The changes now provide a standardized convention for dealing with Intel CPU core names and their variations within the kernel code rather than the naming convention mess that had come about over the years. This doesn't impact end-users, but cleans up the kernel code to be less confusing.

  • Microsoft exFAT File-System Mailed In For Linux 5.4 Along With Promoted EROFS & Greybus

    Greg Kroah-Hartman began volleying his Linux 5.4 kernel pull requests today of the subsystems he oversees. The most significant of this morning's pull requests are the staging area changes that include the Microsoft exFAT file-system support.

    As we've been expecting, Linux 5.4 is bringing exFAT support after last month's surprise announcement by Microsoft publishing the exFAT specification and giving it an open-source blessing for integrating the file-system support at long last into the Linux kernel.

  • Improved Fscrypt Sent In For Linux 5.4 To Offer Better Native File Encryption Handling

    In addition to submitting the FS-VERITY file authentication code for Linux 5.4, Google's Eric Biggers has sent out his big update to the fscrypt file encryption framework for this next kernel revision.

    Fscrypt as a reminder is a kernel framework providing native file encryption support to file-systems. Currently Fscrypt is used by EXT4, F2FS, and UBIFS while being used by Google for at least new Android use-cases. Fscrypt has been around for several kernel cycles now but for Linux 5.4 is seeing its first big update.

Introducing KDToolBox

KDE

At KDAB we invest a significant amount of efforts in research and development. We are always looking for new tooling, libraries and utilities that can make our job easier and improve the C++ and Qt ecosystems. Ultimately, the gained knowledge and skills make our customers happier.

As part of this process we develop lots of code, usually starting as small experiments and/or proof-of-concept. Some of those experiments mature and become fully fledged solutions, such as our famous GammaRay, the introspection tool for Qt applications; hotspot, the GUI to Linux perf; and heaptrack, a heap memory profiler.

Kubernetes 1.16 available from Canonical

Filed under
Server
OSS
Ubuntu

Canonical announces full enterprise support for Kubernetes 1.16, with support covering Charmed Kubernetes, MicroK8s and kubeadm.

MicroK8s will be updated with Kubernetes 1.16 enabling users access to the latest upstream release with a single-line command in under 60 seconds. In addition, MicroK8s gets new add-ons with one line installs of Helm and Cilium as well as enhancements, upgrades and bug fixes. Cilium adds enhanced networking features including Kubernetes Network Policy support. With MicroK8s 1.16, users can develop and deploy enterprise grade Kubernetes on any Linux desktop, server or VM across 42 Linux distros.

Canonical’s Charmed Kubernetes 1.16 will come with exciting changes like support for Kata Containers, AWS IAM, SSL passthrough and more. Using Kata Containers, insecure or untrusted pods can be run safely in isolation without disrupting trusted pods in deployments. Identity Access Management on AWS can be used to login to your Charmed Kubernetes cluster. Users get more control over their deployments while benefitting from reduced complexity due to improved LXD support and enhanced Prometheus and OpenStack integration.

“At Canonical, we enable enterprises by reducing the complexity of their Kubernetes deployments. We are actively involved in the Kubernetes community to ensure we listen to, and support our users’ and partners’ needs. Staying on top of security flaws, community issues and features to improve Kubernetes is critical to us. We keep the Ubuntu ecosystem updated with the latest Kubernetes, as soon as it becomes available upstream,” commented Ammar Naqvi, Product Manager at Canonical.

Linux Distribution Comparison

Filed under
GNU
Linux

There are currently nearly 300 active Linux distributions, which makes choosing just one somewhat difficult, especially if you would rather make your own informed decision instead of relying on the recommendation of someone else. The good news is that the number of major Linux distributions, which stand out in a significant way and are more than simple reskins of existing distributions, is much smaller.
If we were to represent the world of Linux distribution as a map, the 10 distributions listed in this article would be the continents of the world, while other distributions would be islands of various sizes. Just like there is no “best” continent in the real world, the same holds true in the world of Linux distributions.

Each Linux distribution is designed with a different use case in mind, and the same distribution can be perfect for one user and unusable for another one. That’s why the distributions in this article aren’t listed in any particular order and are numbered just for the sake of convenience.

Industrial PC with 6th or 7th Gen Intel CPUs has four PCIe slots for Nvidia graphics

Filed under
Linux

Axiomtek’s “IPC974-519-FL” industrial PC for AI edge applications runs on Xeon E3 or 6th or 7th Gen Core CPUs and offers 4x PCIe/PCI slots for up to 300W Nvidia graphics plus 2x SATA, 2x GbE, and modular I/O expansion.

Axiomtek announced the latest member in its line of IPC (industrial PC) computers with full-sized PCIe/PCI expansion slots. The new IPC974-519-FL computer is very similar to the IPC962-511-FL we reported on last February, which similarly supports Intel Xeon E3 or 6th Gen (Skylake) or 7th Gen (Kaby Lake) Core CPUs. However, the new model has four PCIe/PCI expansion slots instead of two.

Red Hat Enterprise Linux 6 and CentOS 6 Receive Important Kernel Security Update

Filed under
Red Hat

Marked by the Red Hat Product Security team as having a security impact of "Important," the new Linux kernel security update is here to patch a memory corruption (CVE-2018-9568) that occurred due to incorrect socket cloning and a NULL pointer dereference (CVE-2019-11810) discovered in drivers/scsi/megaraid/megaraid_sas_base.c, which could lead to a denial of service.

Also fixed in this update are two bugs affecting the performance of the Linux kernel on Red Hat Enterprise Linux 6 and CentOS Linux 6 systems, namely a fragmented packets timing out issue and the backport TCP follow-up for small buffers. These two bugs can be corrected if you install the new kernel versions for your operating system.

FreeBSD 12 & DragonFlyBSD 5.6 Running Well On The AMD Ryzen 7 3700X + MSI X570 GODLIKE

Filed under
Graphics/Benchmarks

For those wondering how well FreeBSD and DragonFlyBSD are handling AMD's new Ryzen 3000 series desktop processors, here are some benchmarks on a Ryzen 7 3700X with MSI MEG X570 GODLIKE where both of these popular BSD operating systems were working out-of-the-box. For some fun mid-week benchmarking, here are those results of FreeBSD 12.0 and DragonFlyBSD 5.6.2 up against openSUSE Tumbleweed and Ubuntu 19.04.

Back in July I looked at FreeBSD 12 on the Ryzen 9 3900X but at that time at least DragonFlyBSD had troubles booting on that system. When trying out the Ryzen 7 3700X + MSI GODLIKE X570 motherboard on the latest BIOS, everything "just worked" without any compatibility issues for either of these BSDs.

How to break out of a hypervisor: Abuse Qemu-KVM on-Linux pre-5.3 – or VMware with an AMD driver

Filed under
Linux
Security

A pair of newly disclosed security flaws could allow malicious virtual machine guests to break out of their hypervisor's walled gardens and execute malicious code on the host box.

Both CVE-2019-14835 and CVE-2019-5049 are not particularly easy to exploit as they require specific types of hardware or events to occur. However, if successful, either could allow a miscreant to run malware on the host from a VM instance.

CVE-2019-14835 was discovered and reported by Peter Pi, a member of the Tencent Blade Team. It is found in the Linux kernel versions 2.6.34 up to version 5.3, where it is patched.

A Look at KDE Plasma 5.17 Beta and Report From Akademy 2019

  • KDE Plasma 5.17 Beta Run Through

    In this video, we look at KDE Plasma 5.17 Beta, enjoy!

  • TSDgeos' blog: Akademy 2019

    It's 10 days already since Akademy 2019 finished and I'm already missing it :/ Akademy is a week-long action-packed conference, talks, BoFs, daytrip, dinner with old and new friends, it's all a great combination and shows how amazing KDE (yes, the community, that's our name) is. On the talks side i missed some that i wanted to attend because i had to extend my time at the registration booth helping fellow KDE people that had forgotten to register (yes, our setup could be a bit easier, doesn't help that you have to register for talks, for travel support and for the actual conference in three different places), but I am not complaining, you get to interact with lots of people in the registration desk, it's a good way to meet people you may not have met otherwise, so please make sure you volunteer next year ;) One of the talks i want to highlight is Dan VrĂĄtil's talk about C++, I agree with him that we could do much better in making our APIs more expressive using the power of "modern" C++ (when do we stop it calling modern?). It's a pity that the slides are not up so you'll have to live with KĂŠvin Ottens sketch of it for now.

  • Getting started with data science using Python

    Data science is an exciting new field in computing that's built around analyzing, visualizing, correlating, and interpreting the boundless amounts of information our computers are collecting about the world. Of course, calling it a "new" field is a little disingenuous because the discipline is a derivative of statistics, data analysis, and plain old obsessive scientific observation. But data science is a formalized branch of these disciplines, with processes and tools all its own, and it can be broadly applied across disciplines (such as visual effects) that had never produced big dumps of unmanageable data before. Data science is a new opportunity to take a fresh look at data from oceanography, meteorology, geography, cartography, biology, medicine and health, and entertainment industries and gain a better understanding of patterns, influences, and causality. Like other big and seemingly all-inclusive fields, it can be intimidating to know where to start exploring data science. There are a lot of resources out there to help data scientists use their favorite programming languages to accomplish their goals, and that includes one of the most popular programming languages out there: Python. Using the Pandas, Matplotlib, and Seaborn libraries, you can learn the basic toolset of data science.

Excellent Utilities: Liquid Prompt – adaptive prompt for Bash & Zsh

This is a new series highlighting best-of-breed utilities. We’re covering a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides. There’s a complete list of the tools in this series in the Summary section. The Command Line Interface (CLI) is a way of interacting with your computer. And if you ever want to harness all the power of Linux, it’s highly recommended to master it. It’s true the CLI is often perceived as a barrier for users migrating to Linux, particularly if they’re grown up using GUI software exclusively. While Linux rarely forces anyone to use the CLI, some tasks are better suited to this method of interaction, offering inducements like superior scripting opportunities, remote access, and being far more frugal with a computer’s resources. For anyone spending time at the CLI, they’ll rely on the shell prompt. My favorite shell is Bash. By default, the configuration for Bash on popular distributions identifies the user name, hostname, and the current working directory. All essential information. But with Liquid Prompt you can display additional information such as battery status, CPU temperature, and much more. Read more
