This document provides an overview of Bluetooth technology, including its history, logo, how it works, advantages, and common devices. It discusses how Bluetooth was invented in 1994 by engineers at Ericsson to eliminate cables between mobile phones and other devices. It transmits data using radio waves at 2.4 GHz and can connect up to 8 devices within a short range of about 10 meters. Common Bluetooth devices include headsets, keyboards, speakers, and more.
Bluetooth profile
Bluetooth profiles specify standards for Bluetooth communication between devices. A profile defines dependencies, user interfaces, and which parts of the Bluetooth protocol stack it uses. There are many profiles for different use cases like audio streaming, printing, networking, and more.
Bluetooth based smart sensor networks
Bluetooth is a low-cost, short-range wireless technology with
small footprint, small power consumption, reasonable
throughput and hence suitable for various small, batterydriven devices like mobile phones, PDAs, cameras, laptops
etc. Development of the Bluetooth started several years ago
with the intention to replace all sorts of cables used to
connect different devices. In meantime the idea has evolved
and Bluetooth is now developing not just as a point-to-point,
but as a network technology as well.
Bluetooth has gone through periods of big hype when it was
considered as the best short-range technology as well as
through periods when it was considered a failure. However,
the last year could be seen as the turning point year for
Bluetooth. A lot of various Bluetooth devices and accessories
appeared on the market, broad range of users is able to use it
and first experiences are generally positive. The main
challenge in front of Bluetooth developers now is to prove
interoperability between different manufacturers’ devices and
to provide numerous interesting applications. An example of
such applications are wireless sensor networks.
Bluetooth operates in the 2.4GHz frequency band and uses
frequency hopping spread spectrum technique. There are 79
channels, each 1MHz wide, available for hopping.
A Bluetooth device has to be member of a piconet to be able
to communicate with other devices. A piconet is a collection
of up to 8 devices that frequency hop together. Each piconet
has one master, usually the device that initiated establishment
of the piconet, and up to 7 slave devices. Master’s Bluetooth
address is used for definition of the frequency hopping
sequence. Slave devices use the master’s clock to
synchronize their clocks to be able to hop simultaneously.
Wireless sensor networks are an interesting research area
with many possible applications. They are based on
collaborative effort of many small devices capable of
communicating and processing data. There are still many
open issues ranging from the choice of physical and MAC
layer to design of routing and application level protocols.
Bluetooth is a possible choice for data communication in
sensor networks. Good throughput, low-power, low-cost,
standardized specification and hardware availability are
Bluetooth advantages, while slow connection establishment
and lack of scatternet support are some of the deficiencies.
An initial implementation of a Bluetooth based sensor
network platform is presented. Implemented functionality and
various problems experienced during the implementation are
described. Implemented platform presents a good
environment for further research and development of sensor
network protocols and algorithms.

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.
