Hamming numbers, or ugly numbers, or smooth numbers, is a sequence of numbers that they can be produced by : 2^x * 3^y * 5^z Where x, y, z >= 0 For example : It is a sequence that follows a predictable, controllable pattern of incrementation due to their specific structure. It looks like that... » read more
In low-level coding, we usually have to specify the length of a variable. We have many types, including int32 and int64, which represent numbers in binary, using 32 bits or 64 bits, respectively. The int32, of number 4 for example, looks like this: 00000000 00000000 00000000 00000100 That’s it – 32 zeros or ones to... » read more
For a computer, a three-dimensional space is a collection of triangles. In older 3D video games, this was noticeable and everything seemed a bit triangular. This was because, in order to accommodate older hardware, they had to reduce the number of triangles. Nowadays, there are more triangles, so there is more detail and things don’t... » read more
The pilots of the new Boeing 737-NG, around 2019-2020, encountered a particularly vexing issue: all six display units would go blank during landings at certain airports, including: Since the Boeing codebase is closed-source, the exact cause of the issue remains unknown. We only know the nature of the bug, the timeframe in which it occurred,... » read more
In the 1930s, Alonzo Church introduced Lambda calculus. It is a formal system for expressing mathematical logic and computations using functions. Long before computations were performed by machines, they were done by humans, and Lambda calculus helped formalize these processes in written form. Lambda calculus looks like this: λx.x*2 // function that takes input xx... » read more
Databases are used every day, and most of your day you are manipulating a database. When you buy from a shop: Then, you may use the parking, which probably again may have a database for the free spots. At the end, when you open your online GPS app to set your route, you are requesting... » read more
[...]Input : "And why do you ask that?"Response : "Because I care about you." These lines mark one of the earliest recorded human-machine interactions in history. The program responsible for this exchange was Eliza, developed in 1967 at MIT by Joseph Weizenbaum, as the pioneering chat bot aimed at simulating conversations with a human. Written... » read more
Plan 9 was a utopian operating system that failed. It’s vision was to make distributed computing an everyday thing by treating everything as a file. And when we say everything, we mean everything, so even the hardware of each computer – allowing you to share that hardware with other machines easily. Even though this sounds... » read more
On the 4th of June 2024, we mark 28 years since the tragic failure of Ariane flight V88. 28 years later, one can only imagine the mix of emotions that washed over the engineer tasked with uncovering and rectifying the seemingly innocuous error that led to such a colossal event.
Writing code is a creative process that involves using brackets and other symbols to encapsulate logical instructions, creating a framework that helps prevent errors. It’s like placing your thoughts inside brackets, and to excel, precision is key. Software architecture, a broader concept than just writing code, encompasses the art of not only crafting individual pieces... » read more
