During World War II, the US Army and Army Air Forces codes were decoded by the Japanese. Navajo Indians developed a code using their language, which was complex and lacked a standardized alphabet. The code was used by over 400 Navajo Marines in the Pacific battles and was never broken, saving countless American lives. The […]
The Code of Hammurabi is an ancient legal code created by Babylonian King Hammurabi around 17th century BC. It includes 282 laws and has influenced modern legal systems.

The Harmonized Tariff Code is part of the Harmonized Commodity Description and Coding System used by over 200 countries to classify goods into approximately 5,000 commodity groups. The system is organized into numerical chapters and helps nations collect trade statistics, monitor controlled goods, and develop trade policies. Countries assign customs duties according to the product’s […]
The egress code ensures that homes have multiple exits for emergency situations. Bedrooms and basements with living space must have an exit to the outside. The code varies by region and is a minimum standard. It’s recommended to exceed the code for added safety. The egress code is a section of the building code that […]
Tariff codes are assigned to products for tax, customs, and statistical purposes by the World Customs Organization (WCO) through the Harmonized System. Each code can be divided into three sections and is used by national governments and international agencies for trade deals. The Harmonized System is available as a searchable database on the WCO website. […]
Code signing is a security measure used to ensure that software has not been tampered with. The developer signs the program with a cryptographic hash and private key, and the user verifies the signature using a public key. However, code signing can be bypassed by sophisticated hackers, and downloading programs from untrusted sources can still […]
An error code is an identifier for a specific error that has occurred in hardware or software. It is often part of an error message and can be used to troubleshoot and fix the problem. Error codes can be displayed in various ways and can help users and technicians determine the cause of the problem. […]
Distributed source coding (DSC) is a method for compressing related but non-communicating information sources. The Slepian-Wolf theorem, proposed in 1973, sets a theoretical limit for lossless compression in DSC. While the theorem has not been practically achieved, scientists are attempting to reach the limit by maximizing the separation distance between the two coded signals. In […]
Code points are numeric values that represent characters in a character set. Typing on a computer involves multiple translations, with the code point being just one step. Character sets like ASCII and Unicode have different code points for the same character. The computer converts keyboard inputs into binary and compares it with the code point […]
A codepage is a key that describes each character in a character set. It can also refer to the programming page of a web page, file, or program. Code pages are organized into tables with different sizes and are used for different languages and alphabets. The definition of code page is changing to refer to […]
Code refactoring is the process of improving software code each time a change is made, creating a continuous improvement cycle. Management buy-in is important, and guidelines and thresholds should be established for risk management. Trust and respect are key factors, and using this technique allows for the evolution of software with modern tools and frameworks. […]
Managed code requires the Common Language Runtime (CLR) virtual machine, making it more portable and secure than unmanaged code. However, it has an overhead that can affect application response time. Unmanaged code can run without the CLR, making it faster but less portable. “Managed Code” is a term created by Microsoft® Coproration. This term refers […]
