  • Rudimentary KBibTeX client using Kirigami2

    KBibTeX is a bibliography editor (BibTeX and somewhat BibLaTex) used in conjunction with LaTeX and friends. Based on this code base, a SailfishOS client called ‘BibSearch’ exists which allows to search for bibliographic data in various online sources (IEEE Xplore, Google Scholar, ACM Digital Library, …). BibSearch's code makes use of KBibTeX's C++ code, has its user interface implemented in SailfishOS's Silica QML, and provides just two C++ files on its own to glue together everything.

  • Unoon, a tool to monitor network connections from my system

    I always wanted to have a tool to monitor the network connections from my laptop/desktop. I wanted to have alerts for random processes making network connections, and a way to block those (if I want to).

    Such a tool can provide peace of mind in a few cases. A reverse shell is one the big one, just in case if I manage to open any random malware (read downloads) on my regular Linux system, I want to be notified about the connections it will make. The same goes for trying out any new application. I prefer to use Qubes OS based VMs testing random binaries and applications, and it is also my daily driver. But, the search for a proper tool continued for some time.

    [...]

    A few weeks back, on a Sunday late night, I was demoing the very initial version of the tool to Saptak. While we were talking about the tool, suddenly, an entry popped up in the UI /usr/bin/ssh, to a random host. A little bit of search showed that the IP belongs to an EC2 instance. For the next 40 minutes, we both were trying to debug to find out what happened and if the system was already compromised or not. Luckily I was talking about something else before, and to demo something (we totally forgot that topic), I was running Wireshark on the system. From there, we figured that the IP belongs to github.com. It took some more time to figure out that one of my VS Code extension was updating the git, and was using ssh. This is when I understood that I need to show the real domain names on the UI than random IP addresses.

  • Godlike village sim 'Rise to Ruins' has officially left Early Access with a huge upgrade

    Rise to Ruins (formerly Retro-Pixel Castles) is a great blend of genres, pulling in inspiration from the likes of Black and White, Rimworld, and Dwarf Fortress to make something entirely unique.

    After being in Early Access for nearly five years, this is a huge milestone for Raymond Doerr of SixtyGig Games. It's another title I've followed along closely all these years, after personally purchasing it back in 2015 and it's really delightful to play. The Linux support has been in good shape for a long time too, no noteworthy issues.

  • Stranger Things have entered Rocket League for the Haunted Hallows event

    As a big fan of both Stranger Things (the TV series) and Rocket League, I approve of the little crossover they're currently doing for the new Halloween event the Haunted Hallows.

    Running from now until November 11 at 6PM UTC, the Farmstead Arena has been given a bit of a makeover to be a bit more spooky. Complete with a freaky creature called the Mind Flayer watching over the arena. During the event you can once again earn Candy Corn to redeem for new themed in-game items. I'm quite a big fan of the animated spider decal, looks awesome.

OSS

SUSE, formerly a Platinum member of the OpenStack Foundation, may have left the open-source, Infrastructure-as-a-Service (IaaS) OpenStack cloud, but the project is going to move forward with the forthcoming 20th release of OpenStack: Train.

That's because while SUSE may no longer find OpenStack profitable, others are finding it works well for them and for their customers. "OpenStack is the market's leading choice of open-source infrastructure for containers, VMs and bare metal in private cloud," said Mark Collier, COO of the OpenStack Foundation in a statement.

  • PyPy v7.2 released

    As always, this release is 100% compatible with the previous one and fixed several issues and bugs raised by the growing community of PyPy users. We strongly recommend updating. Many of the fixes are the direct result of end-user bug reports, so please continue reporting issues as they crop up.

  • PyPy 7.2 released

    Version 7.2 of PyPy, an implementation of the Python language, is out.

  • PyPy 7.2 Released With Full 64-bit AArch64 Support, PyPy 3.6 Beyond Beta

    PyPy 7.2 is out today as a big update for this alternative Python implementation that currently provides interpreters for compatibility with Python 2.7 and Python 3.6.

    In cooperation with Arm and Crossbar.io, PyPy developers have been working on complete 64-bit ARM (AArch64) support and this summer they achieved getting the PyPy JIT running on 64-bit ARM. PyPy 7.2 is the first release with this 64-bit ARM support now in good standing.

  • Intel Firmware Binaries Land For AX200/AX201 Bluetooth Linux Support

    With devices beginning to hit store shelves using the new Intel WiFi 6 AX200 series chipsets, the firmware binaries have landed in linux-firmware.git for rounding out support for these latest WiFi/Bluetooth adapters.

    For a few kernel releases now since earlier this year these new Intel wireless chipsets have been supported by the mainline kernel but the firmware hasn't been part of the de facto linux-firmware.git tree that houses the various firmware binaries for different hardware component support under Linux.

  • Improving distfile mirror structure

    The Gentoo distfile mirror network is essential in distributing sources to our users. It offloads upstream download locations, improves throughput and reliability, guarantees distfile persistency.

    The current structure of distfile mirrors dates back to 2002. It might have worked well back when we mirrored around 2500 files but it proved not to scale well. Today, mirrors hold almost 70 000 files, and this number has been causing problems for mirror admins.

  • LibreOffice 6.2.7 packages available for Slackware 14.2

    There was a recent update in my repository of LibreOffice packages, but that libreoffice-6.3.2 was just for slackware-current.

    There’s a recent release in the LibreOffice 6.2 stable series as well (ok… five weeks ago, not that recent…), and so I decided to use my build box’s free weekend to come up with packages for LibreOffice 6.2.7.
    This release has a security improvement over previous versions, in that it will popup a warning to the user if a document tries to run an embedded script (similar to existing warning mechanism for embedded macros).

  • Ubucon Europe 2019 in local media

    News from the new Ubuntu distribution, the exploration of the several platforms and many “how to”, rule the 4-days agenda where the open source and open technologies are in the air.

    The Olga Cadaval Cultural centre in Sintra, is the main stage of a busy agenda filled with several talks and more technical sessions, but at Ubucon Europe there’s also room for networking and cultural visits, a curious fusion between spaces full of history, like the Pena Palace or the Quinta da Regaleira, and one of the youngest “players” in the world of software.

    For 4 days, the international Ubuntu Community gathers in Sintra for an event open to everyone, where the open source principles and open technology are dominating. The Ubucon Europe Conference begun Thursday, October 10th, and extends until Sunday, October 13th, keeping an open doors policy to everyone who wants to

    Afterall, what is the importance of Ubucon? The number of participants, which should be around 150, doesn’t tell the whole story of what you can learn during these days, as the SAPO TEK had the opportunity to check this morning.

    Organised by the Ubuntu Portugal Community, with the National Association for Open Software, the Ubuntu Europe Federation and the Sintra Municipality, the conference brings to Portugal some of the biggest open source specialists and shows that Ubuntu is indeed alive, even if not yet known by most people, and still far from the “world domain” aspired by some.

  • Win Enterprises unveils Atom-based LAN gateway and compact SBC

    Win Enterprises unveiled a fanless “PL-82000” networking gateway with 6x GbE and 2x SFP ports based on an Atom C3000. It also launched a Raspberry Pi sized “MB-5000” SBC that runs Ubuntu or Win 10 on Intel Apollo Lake.

    We tend to forget Win Enterprises because as its name suggests, the company typically sticks to Windows-supported products. Yet, they have increasingly produced barebones products without listed OS support, such as the new PL-82000 networking appliance, as well as Linux supported systems such as the MB-5000 SBC announced back in June. (In 2017, we covered an Intel Bay Trail based MB-80580 SBC and Win IoT-380 Gateway with Linux support.)

  • Raspberry Pi 4 PCI Express: It actually works! USB3, SATA… GPUs?

    Recently, Tomasz Mloduchowski posted a popular article on his blog detailing the steps he undertook to get access to the hidden PCIe interface of Raspberry Pi 4: the first Raspberry Pi to include PCIe in its design. After seeing his post, and realizing I was meaning to go buy a Raspberry Pi 4, it just seemed natural to try and replicate his results in the hope of taking it a bit further. I am known for Raspberry Pi Butchery, after all.

  • Raspberry Pi 4 B+ - PCI Express

    Why did I do it? Because I wanted to see if it can be done. Because Raspberry Pi 4 might be the cheapest device that is PCIe capable after a relatively minor modification (if I didn't lift the capacitors when desoldering the VL805, this is literally 12 soldering points). That, in turn, can be quite handy for developing own PCIe cores for various FPGA based experiments.

    I'm sharing it to allow people to learn from this - and to dispel the myth that PCIe is somehow out of reach of hobbyists due to some concerns over signal integrity or complexities. Stay tuned for more Pi4/PCIe experimentation!

  • Becoming Better Digital Citizens Through Open Source

    The WordPress Project is on a mission to democratize publishing. As WordPress empowers more people to participate in the digital space, we have the opportunity to make sure that everyone can participate safely and responsibly. Today marks the start of Digital Citizenship Week. We are going to share how open source can be used as a tool for learners (regardless of age) to practice and model the essential parts of being a good digital citizen.

    [...]

    Digital Citizenship is for all age groups. Anyone who uses the internet on a computer, mobile device or a TV is a digital citizen. You don’t have to be tech-savvy already, maybe you are taking your first steps with technology. Digital Citizenship Week is a chance to reflect together on our impact on the digital world. It can help us to make our consumption more considered and our interaction friendlier. It enables us to make a positive difference to those around us.

    All of us can strive (or learn) to become better digital citizens. It can be affected by the access those teaching have had to digital skills and good practice. Adult education classes and community tech hubs play a part in basic tech skill development. Unfortunately, these are not always accessible to those in less populated geographic locations. 

    Open source communities like WordPress already make a difference in encouraging the principles of digital citizenship, from sharing tech skills to improving security knowledge. They give people an opportunity to learn alongside their peers and many of the resources are available regardless of location, resources, or skills.

  • MongoDB vs. MySQL: How to choose

    During the dot-com bubble in the 1990s, one common software stack for web applications was LAMP, which originally stood for Linux (OS), Apache (web server), MySQL (relational database), and PHP (server programming language). MySQL was the preferred database mostly because it was free open source and had good read performance, which fit well with “Web 2.0” apps that dynamically generated sites from the database.

    Later the MEAN stack, which stood for MongoDB (document database), Express (web server), AngularJS (front-end framework), and Node.js (back-end JavaScript runtime), came to prominence. The MEAN stack was attractive, among other reasons, because the only language you needed to know was JavaScript. It also needed less RAM than an equivalent LAMP stack.

Security: XML External Entity (XXE) Example and the Latest Patches

Filed under
Security
  • XML External Entity (XXE) Example

    According to OWASP, an XML External Entity attack is a type of attack against an application that parses XML input. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data, denial of service, server side request forgery, port scanning from the perspective of the machine where the parser is located, and other system impacts.

    If a parser accepts unsanitized XML, we can take advantage of that and send our own crafted external XML payload to exploit our target. This post won’t be long so let’s get into it.

Linux Virtualization Manager can manage multiple on-premises hosts running Oracle Linux KVM. Oracle enhanced Linux KVM in the Unbreakable Enterprise Kernel (UEK) Release 5, an OS kernel tested and optimized for Oracle Linux 7 Update 5.

Because Linux KVM is the same hypervisor used for Oracle Cloud Infrastructure, admins have an easy migration path from the Linux Virtualization Manager environment to the Oracle Cloud platform. Linux Virtualization Manager also supports importing and exporting software appliances based on the Open Virtualization Format and Open Virtualization Archive standards.

Oracle based Linux Virtualization Manager on the oVirt project, an open source virtualization platform developed by Red Hat. Linux Virtualization Manager relies on the oVirt engine for discovering KVM hosts and configuring storage and network resources. The platform supports KVM administration for multinode environments, offering a large-scale, centralized management platform for server and desktop virtualization.

Linux Fu: Python GUIs For Command Line Programs (Almost) Instantly

Filed under
Development
GNU
Linux
HowTos

Not every programmer likes creating GUI code. Most hacker types don’t mind a command line interface, but very few ordinary users appreciate them. However, if you write command line programs in Python, Gooey can help. By leveraging some Python features and a common Python idiom, you can convert a command line program into a GUI with very little effort.

The idea is pretty simple. Nearly all command line Python programs use argparse to simplify picking options and arguments off the command line as well as providing some help. The Gooey decorator picks up all your options and arguments and creates a GUI for it. You can make it more complicated if you want to change specific things, but if you are happy with the defaults, there’s not much else to it.

At first, this article might seem like a Python Fu and not a Linux Fu, since — at first — we are going to focus on Python. But just stand by and you’ll see how this can do a lot of things on many operating systems, including Linux.
