  • How To Install MongoDB on Ubuntu 22.04 LTS

    In this tutorial, we will show you how to install MongoDB on Ubuntu 22.04 LTS. For those of you who didn’t know, MongoDB is a document-oriented NoSQL database used for high-volume data storage. Instead of using tables and rows as in the traditional relational databases. MongoDB is available in two editions: Community and Enterprise.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database server on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

  • How to Install Python Pip on Ubuntu

    Pip is the recommended package installer for python, with which you can install any python library or package that is present in the Python Package Index (and other indexes).

    Pip is a command-line tool that is cross-platform, featuring easy-to-use commands to manage your python packages. Like Python, pip has two versions, Pip 3 for Python 3 and Pip 2 for Python 2.

    This article explains how to install both of them in Ubuntu 20.04 (the guide works for other releases of Ubuntu and most Debian-based distros).

  • Using a Linux phone as a secondary monitor

    As a software developer on the go, one of the very first use cases that I started investigating after installing Linux on my first tablet was that of using a portable device as a secondary display for another Linux machine. Ideally, this would happen wirelessly (or wired, if that involved lower power consumption), with unnoticeable delay, and - why not - even including real-time touchscreen input.

    The journey, however, took longer than planned. Existing solutions, like VNC, tend to be strangely laggy, and others, like Miracast, are so deeply enclosed in proprietary protocols that they do not scale well to a bug-free experience on all devices. The first solution to this problem, at an even less stable stage than currently, was my most shared post ever on Twitter, so I decided to write a post on how this was done.

  • Easily Add Startup Sounds To Your Linux Desktop - Invidious

    One of the most striking features of operating systems of the past were the startup sounds when you logged into your computer. For whatever reason, most Linux desktops don't incorporate a startup sound. But we can easily add one, regardless of distribution or desktop environment or window manager.

  • 15 Open-source Physics Simulation Engine

    A physics simulation engine is a custom software engine that grants developers add visual effetcs, simulate and tweak objects and enviroments accroding to the law of physics in 2D, 3D or both. With physics engine software, developers and artists apply real-world physical properties, such as gravity and momentum, to their 2D and 3D objects rather than designing them from scratch.

  • FLOSS 2.0 Has Been Released [Ed: The acronym "FLOSS" is being hijacked]

    When you have to deal with malware in your day job, for research purposes, or just for fun, one of the key points is to have a lab ready to be launched. Your sandbox must be properly protected and isolated to detonate your samples in a safe way but it must also be fulfilled with tools, and scripts. This toolbox is yours and will be based on your preferred tools but starting from zero is hard, that's why there are specific Linux distributions built for this purpose. The one that I use in FOR610 and for my daily investigations is REMnux[1], created and maintained by Lenny Zeltser[2]. This environment offers tons of tools that help to perform all the malware analysis steps from static analysis up to code reversing and debugging.

  • odcast: Why there were 56 OT vulnerabilities this week

    This week we cover the Ericsson mobility report that offers some stats on cellular IoT connections, including the surprising nugget that we won’t see 4G/5G connections surpass 2G/3G connections until some time next year. Then we hit another report. This one is from NPR and covers the state of audio and smart speakers. It proves that growth is slowing for smart speakers and that we may not do as many things with voice as we think. In dystopian news we cover China using COVID tracking apps to lock down protesters, and Microsoft stopping sales of some facial recognition tools. In new product news we talk about the latest Philips Hue gear, a new material that could generate electricity for wearables, and new MCUs from NXP. We also address the closure of SmartDry and explain how Google’s update on the Nest Max Hub may break your Nest x Yale lock. We end by answering a listener question about more accurate motion sensors.

  • Cortex XSOAR Tips & Tricks – Creating indicator relationships in automations

    In Cortex XSOAR, indicators are a key part of the platform as they visualize the Indicators Of Compromise (IOC) of a security alert in the incident to the SOC analyst and can be used in automated analysis workflows to determine the incident outcome. If you have a Cortex XSOAR Threat Intelligence Management (TIM) license, it is possible to create predefined relationships between indicators to describe how they relate to each other. This enables the SOC analyst to do a more efficient incident analysis based on the indicators associated to the incident.

  • Social Engineering Kill–Chain: Predicting, Minimizing & Disrupting Attack Verticals

    It was a Friday afternoon when Bill was on his way back home from work when he received a call that made him take the next U-turn back to his office. It was one of these calls that he was dedicating all of his working hours to avoid. He was not given much detail through the phone, but it seems that Andre, someone working in the account payments department, had just fallen victim to a scam and had proceeded to a hefty payment. A scam? Bill recalled all the training videos he had put this department through. What went wrong?

Windows vs Linux: What's the best operating system?

The way you utilise your PC can often depend on the operating system you use as well as your level of technical knowledge. Even though most people will turn to macOS or Windows when deciding on an OS, if you want something you can customise, there's nothing better than Linux. Despite the fact that it isn’t as popular as Windows, Linux offers far more avenues for customisation than any other OS as it's built on an open source foundation. It's certainly more intimidating to the average user as a result, but it can be incredibly powerful, and rewarding, if you possess the skills to fully take advantage of it. Obviously, there are advantages and disadvantages with both systems that are useful to know before making the decision on which is best for you. Read more

In a new FreeBSD system, an audio card will need to be configured to process audio files and send them to the connected speakers. Our newest FreeBSD quick guide will walk through setting up and configuring audio, connecting a pair of headphones (including pairing Bluetooth models), and testing the system’s sound, all in under 10 minutes!

  • Speeding up autoconf with caching - Julio Merino (jmmv.dev)

    In the recent Remembering Buildtool post, I described how setting up a cache of configuration checks was an important step in Buildtool’s installation process. The goal was to avoid pointless repetitive work on every build by performing such common checks once. Episode 457 of BSD Now featured my post and Allan Jude wondered how much time would be saved in a bulk build of all FreeBSD packages if we could just do that same kind of caching with GNU Autoconf. And, you know what? It is indeed possible to do so. I had mentioned it en passing in my post but I guess I wasn’t clear enough, so let’s elaborate!
