Introduction to beamforming antennas
Beamforming antennas use an array of antennas to transmit radio signals in a targeted direction rather than broadcasting uniformly. They can concentrate signals into beams through adjusting the phase and amplitude of each antenna (analog beamforming) or processing multiple data streams digitally. Beamforming is commonly used in 5G networks using massive MIMO antennas to improve efficiency and data rates. Testing beamforming antennas presents challenges due to the integration of radio and antenna units, requiring evaluation of more parameters over-the-air rather than just in conducted tests. Standardized test methods include using anechoic chambers, compact antenna test ranges, and plane wave synthesizers to simulate far-field conditions.

Handover Overview
There are three types of WCDMA handovers: intra-frequency, inter-frequency, and inter-system. Intra-frequency handovers occur within the same frequency and support soft, softer, and hard handovers. Inter-frequency handovers are between different frequencies within the same system and only support hard handovers. Inter-system handovers are between different systems, such as WCDMA to GSM, and only support hard handovers. Soft handovers connect the user equipment to multiple base stations simultaneously, softer handovers occur within one base station but between sectors, and hard handovers release the source before adding the new connection.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
