The Antenna Farm is a distributor of two way radios, antennas, coax cables, coax connectors and related accessories. Many police and fire departments, EMS companies, public service organizations as well as the average consumer rely on us for a wide variety of high quality two-way radio products from industry leading brands.

Having been in business for over 20 years, The Antenna Farm has developed a wealth of expertise and experience in the two-way radio industry and is always happy to help our customers choose the best equipment for their particular needs and budgets.

Since 1988, we have been developing and manufacturing high-frequency components and devices for well-known industrial companies, research institutions and ham radio operators. High Frequency components for industry and research.

TINKERplate is the first Pi-Plate that is fully compatible with the Raspberry Pi HAT standard. With this design, we have borrowed features from our other products and squeezed them down onto this tiny form factor. And like all Pi-Plates, you can increase the number of available I/O ports by stacking up to eight TINKERplates.

On 10/10/2023, Debian Bookworm was released for the Raspberry Pi. This OS has a number of new features that improve the GUI as well as some behind the scenes improvements. One change however, is going to be a little painful for users of Python. Specifically, any code that uses a library added via the pip utility has to be executed inside a virtual environment. While the reasons for doing this are valid (see PEP 668 for more details), the solution is somewhat draconian. Perhaps a more elegant solution will arrive in a later release of the OS, but until then, you can choose to either hold off upgrading to Bookworm (and stay with Bullseye) or to do the following:

USBView is a small GTK application to show what the device tree of
the USB bus looks like. It shows a graphical representation of the
devices that are currently plugged in, showing the topology of the
USB bus. It also displays information on each individual device on
the bus.

The goal of this article is to illustrate the potential for cool applications when software is combined with custom hardware. I will provide a brief introduction to USB and how communication with a custom device can be used to create an annoying gadget.

This is about "what I know thing", and I can be wrong about what I'll show you specially in this article. If you find out that I'm wrong please let me know so we can discuss it further.

This is my second article, and it about how to monitor URB (USB Request Block) which is used by USB device driver. Honestly, I do not know exactly how USB protocol work, well, in fact I got this idea when I try to understand how to write USB driver. If you want to know exactly how this protocol work, please take a look at official USB "specification maintainer". The basic idea is the same as my previous article but this time with little bit variation.

This talk presents the hidden risks of managing identities and access in a multi-cloud environment. We will expose access flaws and misconfigurations that attackers can easily abuse to gain access to confidential and sensitive information. We will discuss the inner workings of each cloud provider's Identity and Access Management (IAM) layers and highlight the differences between each cloud service. We then detail how inconsistent entitlements across cloud resources and services can lead to unintended access and how accountability confusion in the shared responsibility model can enable privilege escalation.
