SIZE SEPARATION
This document discusses size separation techniques used to separate particles of different sizes. Size separation, also known as sieving or screening, is important to obtain particles of a narrow size range or uniform particle size. It improves properties like mixing, flow, and suspension stability. Common mechanisms of size separation include agitation (oscillation, vibration, gyration), brushing, and centrifugal forces. Standard sieves made of woven wire or mesh are used to separate particles according to their ability to pass through openings of different sizes. Instruments like sieve shakers, cyclones, air separators, and filter bags can be employed for size separation in pharmaceutical applications.
Cyclone separator
The document discusses cyclonic separators and hydrocyclones. Cyclonic separators use centrifugal force to separate particulate matter from gas streams. Gas enters tangentially and spins rapidly, forcing particles outward against the wall to fall into a collection hopper while clean gas exits through the center. Hydrocyclones separate particles in liquid suspensions based on density and size differences, with denser/coarser particles exiting the bottom and lighter/finer through the top. Both devices have various industrial uses like dust collection and mineral processing.
Cyclone separator
Cyclone separators use centrifugal force to remove particles from an air or gas stream. As the gas spins rapidly inside the separator, heavier particles are forced outward by centrifugal force and collect on the outer wall. There are several types of cyclones including vertical cyclones for liquid/solid removal, single cyclones that create dual vortexes to separate coarse and fine particles, and multi cyclones which consist of several small diameter cyclones operating in parallel for more efficient separation. The design of a cyclone separator is based on parameters like cylinder length, cone length, entrance/exit diameters, and collection efficiency depends on particle size, centrifugal force exerted, and time force is applied.
Cyclone separator
The document discusses cyclone separators. It explains that a cyclone separator uses centrifugal force to separate particles from a gas or liquid stream without any moving parts.

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:
