Cava is a free, open-source audio visualizer that works on Linux, FreeBSD, macOS, and Windows, letting you see music as moving bars right in your terminal or desktop window[1][3]. It’s easy to install and use, supports many audio systems, and lets you customize colors and settings. The main benefit is that it makes listening to music more fun and visually engaging, especially for people who enjoy seeing sound represented in real time, and it works on almost any computer or device[1][3][4].

⚡ 25,000 U.S. businesses already use macOS, and the number keeps growing. Yet macOS threats are still flying under the radar for most security teams.
Attackers know this. 👀 And they're quietly adding more cross-platform threats to take advantage of it, targeting sensitive data.
That's exactly why #ANYRUN just levelled up. The sandbox now supports #macOS alongside #Windows, #Linux, and #Android — one unified place, full visibility, faster verdicts.

This is Probably the Best Video Downloader App (And it is Free and Open Source) | itsFOSS
VidBee allows you to download videos from YouTube, Facebook, X, Instagram, etc. In fact, it supports over 1,800 websites.
It is built on top of popular command line tools like yt-dlp and #ffmpeg. For the interface, it uses the Electron framework. I understand that some people dislike Electron framework as it runs a web browser underneath, but the 'advantage' of this framework is that you get the same interface in all the operating systems. At least, it's an advantage for the developers as they don't have to build the interface separately for #Linux, #Windows and #macOS.
The source code for VidBee is available on its GitHub repository.

In this post we gonna tell you about How to start/stop/get for the #google compute instance with python.
Sometimes we don’t want (or need) a compute engine instance running 24hs every day but we need to run #task/s periodically. To solve this we can have an app engine task runing using cron service to start the VM instance. Once the VM has started, it can have a startup script that runs the actual task it was needed for and then stops the machine.

#Linux devices have a unique identifier called machine-id. Here is how to change it.
Posted on February 24, 2021
What is a machine-id, and why should you randomize it? From the machine-id man pages, it is defined as:
This ID uniquely identifies the host. It should be considered “confidential”, and must not be exposed in untrusted environments, in particular on the network. If a stable unique identifier that is tied to the machine is needed for some application, the machine ID or any part of it must not be used directly.
https://www.man7.org/linux/man-pages/man5/machine-id.5.html
In an effort to promote privacy, having a unique and unchanging identifier tied to your device seems like the wrong approach. It’s quite possible that poorly coded or even maliciously coded software could fetch this ID from your system. Let’s make sure that even if that does happen, that the value is constantly changing so that your device can not be uniquely identified as your device.
This is an incredibly simple and quick adjustment to your default Linux system. What we’re doing is showing you how to either adjust this value manually by hand, or by running a cronjob to change this value every minute with a new, randomized value.
Before we begin, a disclaimer: We’ve tested this on our own work desktops and development environments and I’ve tested it on my daily driver desktop. We have not found that anything has ‘broken’ because of this, but this is untested in many environments and may not be suitable for your use. It’s always reversible if you later wish to continue with a single, uniquely identifying ID attached to your device(s).
Debian / Ubuntu systems
To check your machine-id, open up your terminal and enter the following:
cat /etc/machine-id
The output should look a little something like this:
a9976154f0084a3782892638656ad9fd
You’ll note that this value is also stored in /var/lib/dbus/machine-id and that a symlink between the two exist. Any change to one file, will be reflected in the other.
me@virtbox-testing:~$ cat /etc/machine-id a9976154f0084a3782892638656ad9fd me@virtbox-testing:~$ cat /var/lib/dbus/machine-id a9976154f0084a3782892638656ad9fd
If you reboot your device, you’ll notice that this value remains unchanged. So, let’s change it ourselves!
Method 1: Manually.
Method 2 is automatically, every minute, as ran by a cron-job. If you don’t want to fully commit to that, you can change your machine-id by hand manually whenever you feel like it.
Step 1, remove the old machine-id file.
sudo rm /etc/machine-id
Step 2, recreate the machine-id file.
sudo systemd-machine-id-setup
Step 3, confirm that /etc/machine-id (and /var/lib/dbus/machine-id) now show a new value, different from the original.
cat /etc/machine-id && cat /var/lib/dbus/machine-id
That’s it! You should see two lines in your output with matching IDs that differ from the original machine-id you had in the beginning.
me@virtbox-testing:~$ cat /etc/machine-id && cat /var/lib/dbus/machine-id a78badce3e73beced163bbef7e55232a a78badce3e73beced163bbef7e55232a
You’ve changed your device’s uniquely identifying machine-id. This change will survive device reboots and will remain the same until you create a new one.
Method 2: Changing every 1 minute, automatically.
If the above didn’t satisfy your needs, than feel free to automate the creation of a new machine-id by creating a cronjob entry that will generate a new ID every minute.
Step 1, open up your crontab file.
sudo crontab -e
Step 2, enter at the bottom of the file the following:
*/1 * * * * sudo rm /etc/machine-id && sudo systemd-machine-id-setup
Save and Exit.
Step 3, wait a minute and confirm that your machine-id value has changed:
cat /etc/machine-id && cat /var/lib/dbus/machine-id
You should see two new matching values, that differs from the original value you had at the start. Wait a minute and run the step 3 command again, and you’ll see that these values have changed.
🚨 QLNX, a previously undocumented #Linux RAT, is targeting developers and DevOps systems to steal npm, PyPI, AWS, Kubernetes, Docker, and CI/CD credentials.
The malware uses fileless execution, PAM backdoors, eBPF rootkits, and 58 remote commands to maintain covert access and hijack software supply chains.
