  PM2.5 Air Pollutants: Tiny Particles That Can Have Huge (Health) Consequences HIGHLIGHTS: PM2.5 air pollutants can be inhaled deep into the respiratory system and lungs. The effects of this include irritation, a stinging nose, the buildup of phlegm, coughing, sneezing, asthma attacks, cardiac arrest, ischemic strokes and, most dangerous of all, lung cancer. Outdoor exercise should be avoided during periods of smog and high air pollution, as strenuous activity or heavy breathing may lead to increased levels of PM2.5 pollutants being ingested into the respiratory system and lungs. N95-protective masks must be worn correctly, ensuring that it fits tightly on the face. Also, previously worn masks should be thrown away instead of being used again. The World Health Organization (WHO) has set an average rate for PM2.5 air pollutants, stating that if there are over 25 micrograms per cubic meter, it is seen as being dangerous to health. At the same time, Thailand has put the levels at whi...

  TYPES OF PLASTIC - A COMPLETE PLASTIC NUMBERS GUIDE  W hether we like it or not, we are all living in a world full of various types of plastics. If you open the fridge or simply look around, you will spot dozens of plastic items that you use every day. Have a closer look and you will notice a recycling symbol at the bottom, top, or side of each plastic object. This recycle sign looks like a triangle of chasing pointers with a number from 1 to 7 inside it. The recycle symbol provides important data about the used resin and recyclability of the item. Keep in mind that the plastic recycle code on the object does not surely mean that the item can be reprocessed. It just shows the information about the recycling possibility. It seems almost impossible to escape plastic in the modern consumer world. Still, we can make a better choice by choosing safer for our health and environment types of plastic. Therefore it is crucial to understand the potential harm of the elements of differ...

  Which Software Development Career Path Should I Take? I started as a Self-Taught Programmer. The thing I've noticed most about people who decide they want to switch careers to become software engineers is how overwhelmed they are by the number of decisions they need to make. Someone looking to break into software engineering needs to decide what type of developer they should become, what programming language and stack to learn and what resources they should use to attain all this knowledge. Getting started learning to code can be so overwhelming that many people give up before they begin. This article will answer the question: What software development career path should I take?  Software Development Career Paths You can take many career paths as a  software developer . For example, you can go into web development, mobile app development, blockchain development, data science or machine learning and artificial intelligence. Let's look at each of them.  Web Developme...

C hoosing the right database for an application depends on various factors including the nature of the data, the scale of the project, performance requirements, and specific features needed. Here's a simplified guide to help you understand which type of database might be suitable for different kinds of applications, considering flexibility, simplicity, performance, and querying capabilities: Simple Web Applications : SQLite: For small-scale, low-traffic applications, or for prototyping. MySQL/PostgreSQL: For more robust, relational database needs with moderate traffic and complexity. Applications Requiring Flexible Schema : MongoDB: When your data doesn't fit well into tables or when you need a flexible schema that can evolve over time. CouchDB/Couchbase: If you need a schema-less database with a focus on ease of use and replication. High Traffic Web Applications : MySQL/PostgreSQL with Replication: For relational data needs with high read and write operations. Cassandra/Scylla...

  What is API latency and why does it matter? API latency is influenced by many factors, such as network speed, server load, data size, and API design. It can vary depending on the type, complexity, and frequency of the requests and responses. API latency matters because it affects the user experience, the scalability, and the reliability of your applications. If your API is too slow, your users may get frustrated, lose interest, or abandon your application. If your API is inconsistent, your application may behave unpredictably, cause errors, or crash. If your API is unreliable, your application may fail to function properly, lose data, or compromise security. How to measure API latency? To measure API latency, you need to use tools that can monitor and analyze the performance of your API endpoints. These tools can help you track the response time, the error rate, the throughput, and the availability of your API. Some examples of these tools are Postman, Curl, Fiddler, and JMeter. ...

Introduction The bicycle, a symbol of freedom and innovation, has a rich history spanning over two centuries. From its earliest form as a wooden frame to the high-tech carbon fiber models of today, the bicycle has continually evolved. Join us on a journey through the complete history of the bicycle, presented in a detailed year-wise timeline. The Dawn of Cycling: 19th Century Innovations 1817: The Draisine Invented by Baron Karl von Drais, this was the first two-wheeled steerable machine, essentially a precursor to the modern bicycle. 1863: The Velocipede or "Boneshaker" Developed by Pierre Michaux and Pierre Lallement, introducing pedals to the design. The Age of Elegance and Speed: Late 19th Century 1870s: The High-Wheeler Known for its large front wheel, these bicycles became a symbol of the era. 1885: The Safety Bicycle John Kemp Starley's design introduced equal-sized wheels and a chain drive, setting the standard for future bicycles. 1888: Pneumatic Tires John Boyd ...
