• [...]

• To remove Windows from the UEFI boot menu after installing Ubuntu, you need to access the terminal, identify the Windows boot entry using the efibootmgr command, remove the boot entry using the efibootmgr -b -B command, delete the Windows folder from the EFI partition, and update GRUB to hide the GRUB menu.

=> ↺ APNIC ☛ Don’t leave network blind spots

• In this post, I discuss recent research by Hassan Habibi Gharakheili, Vijay Sivaraman, and myself from the School of Electrical Engineering and Telecommunications, University of New South Wales that presents a solution for monitoring the enterprise hosts with fine-grained visibility into their network behavioural profiles.

• This research passively analyses network traffic from/to all connected hosts in an enterprise network, regardless of their SOE configuration status. By constructing specialized network behavioural profiles with AI-based classifications, real-time inference on the network behavioural patterns of hosts and potential anomalies are generated for IT departments.

=> ↺ Terence Eden ☛ Shakespeare Serif – an experimental font based on the First Folio

• Now, before setting off on a journey, it is worth seeing if anyone else has tried this before. I found David Pustansky’s First Folio Font. There’s not much info about it, other than it’s based on the 1623 folio. It’s a nice font, but missing brackets and a few other pieces of punctuation. Also, no ligatures. And the long s is in the wrong place.

• So, let’s try to build a font!

=> ↺ Medium ☛ Operating a SOC Analyst Home Lab

• The cybersecurity industry is vast and entails many specialized topics. No one person can learn or know everything and the breadth of concepts to learn can seem overwhelming. Admittedly, I spent a considerable amount of time looking at the different types of cybersecurity career paths out there. On that note, one of the best decisions I’ve made regarding cybersecurity education and career insights was joining the WreckItmech Oxvmx TechHub server on Discord. It’s a safe supportive space where seasoned and aspiring cybersecurity professionals can communicate with each other.

=> ↺ Make Use Of ☛ How to Fix the Ubuntu 23.04 Login Error on VMware

• Ubuntu 23.04 was released to the public in April 2023 with support until April 2024. Although an interim release, major updates such as a better GUI with GNOME 44, GPU support with Mesa 23 drivers, and overall faster performance through the Linux 6.2 kernel had many people trying it out as a virtual machine.

• However, if you try installing Ubuntu 23.04 on VMware, you’ll likely face a login problem even if you’ve configured your machine correctly.

• If you’re having trouble with the login screen when trying to install “Lunar Lobster” on VMware, below is a step-by-step on how to fix the problem.

• With some really fun animated ASCII artwork, Stone Story RPG is a really interesting mixture of an auto-RPG with strategic combat, crafting, programming and more. An incredibly unique game where descriptions and screenshots really don’t tell you enough, you need to watch it and experience it to actually get it. Just be careful, this one is easy to get lost in for hours and hours.

=> ↺ Kdenlive ☛ Kdenlive 23.08 beta available

• After an inspiring participation to Akademy, where we presented some of the actions we want to take to improve Kdenlive’s stability and reliability, we are announcing the first beta version for the upcoming Kdenlive 23.08.0 version.

• The Kdenlive 23.04.x version was unfortunately affected by major regressions related to the new timeline nesting feature.

• We are now working on major improvements to our test suite pipeline to ensure such things don’t get unnoticed before a release. In the meantime, all major issues related to nesting, as well as many other bugs, are now fixed in this new beta and we encourage all interested users to test this version to ensure we have the best possible experience for the final release.

Distributions and Operating Systems

=> ↺ HaikuOS ☛ [GSoC 2023] VPN Support Project Update #4

• So we are just past the midway point for GSoC and last update I told you guys that I had a working (albeit somewhat buggy) TUN Driver working. I had gotten great feedback from Pulkomandy, Axel, and Korli to help with a more efficient driver and to make it more human-readable because it made no sense the way I had written it. I have very good news to bring to everyone in that all of the 3 main problems that I talked about last time are all solved! I think most of them got solved after I fully understood creating semaphores and imposed execution order by adding a write semaphore. While this new code made the driver much more efficient and less error-prone, there were two new errors that popped up during testing: [...]

=> ↺ ZDNet ☛ CIQ spins out its own Red Hat Ansible interface take: Ascender

• CIQ, Rocky Linux’s founding support and services partner, has customized its own take, Ascender on the Ansible AWX front end to the popular DevOps program Ansible.

• Best known for supporting Rocky Linux, CIQ also offers high-performance computing (HPC) and server management programs such as Fuzzball, Warewulf, and Apptainer. Now, it’s taken the open-source Ansible AWX, a web-based user interface, application programming interface (API), and task engine built on top of the Ansible DevOps program to create its own DevOps interface take. Ascender AWX is also one of Red Hat Ansible Automation Platform (RHAP)’s upstream projects.

• Red Hat recently changed the rules for getting Red Hat Enterprise Linux (RHEL) open-source code. This ticked off the RHEL clone vendors, such as AlmaLinux and Oracle Linux. In particular, the Rocky Linux Software Foundation (RLSF) strenuously objected to this and has elected to keep building Rocky Linux off RHEL source code.

• Recently the Linux Mint team released their latest version of Linux Mint, 20.1 Ulyssa, and we as Linux enthusiasts are of course always eager to find out what is new and what has changed. Because Linux Mint is always based on the latest Ubuntu LTS base and will stick to it until the next Ubuntu Long Term Support release is available, the interim Linux Mint point releases like 21.2 are mostly an evolution and not a revolution. But nevertheless, the team behind Linux Mint always comes up with and implements handy, productive, and really nice improvements. So let’s see what is new in Linux Mint 21.2 Victoria.

• I started with three Picos connected by their I2C ports – one as an I2C controller and two I2C processors, all powered by individual USB cables and connected via a strip of Veroboard. A quick test in MicroPython proved that it was workable but, as we are aiming for speed, I quickly swapped to C. Luckily, there is example code for the Pico I2C Slave in Raspberry Pi’s C GitHub, and this formed the basis for the Processor-to-Processor communication.

Productivity Software/LibreOffice/Calligra

=> ↺ ccache for a 5 minute LibreOffice build!ccache for a 5 minute LibreOffice build

• If you have ever tried to build LibreOffice code, you know that it can take a lot of time. LibreOffice has ~6 million lines of C++ and some Java code (<280k). But, there are tools that can help you build LibreOffice from source code much faster, if you do it repeatedly! Here I discuss how.

• Even with a fast computer, compiling huge amount of C/C++ code takes a lot of time. Compiling 6 million lines of C/C++ code in LibreOffice will take you several minutes (if not hours) with a decent computer with fast CPU and a lot of RAM.

• But, people who work on developing LibreOffice need to build it from the source repeatedly. Because only a fraction of the code changes each time, there is a big chance that one can re-use the compiled objects, and that’s where ccache (and similar tools) come in. It caches the compiled objects, and before trying to re-compile the code, searches inside the cache to see if a previously compiled objects are usable.

• Greta Galli is a 20-year-old maker – as well as a content creator, student and teacher! – focusing her high energy levels on robotics and 3D printing. If you think that’s a lot, it is. But keep in mind she got her first taste of making at the young age of 11, when she took part in a kids’ workshop at a tech fair. Fast forward a few years and she heard her high school would start teaching with Arduino, so she jumped the gun and bought her first board.
