Studying productivity is challenging. About 15-20 years ago, I was obsessed over my own productivity. I created a spying agent to monitor my activities and time...Daniel Lemire From Daniel Lemire's Blog | July 12, 2025 at 01:19 PM
The Apple M2, introduced in 2022, and the Apple M4, launched in 2024, are both ARM-based system-on-chip (SoC) designs featuring unified memory architecture. That...Daniel Lemire From Daniel Lemire's Blog | July 9, 2025 at 04:33 PM
JSON, or JavaScript Object Notation, is a lightweight data-interchange format. It is widely used for transmitting data between a server and a web application, due...Daniel Lemire From Daniel Lemire's Blog | July 4, 2025 at 09:49 AM
C and C++ compilers like GCC first take your code and produce assembly, typically a pure ASCII output (so just basic English characters). This assembly code isContinue...Daniel Lemire From Daniel Lemire's Blog | July 3, 2025 at 09:38 AM
Back when I started programming, project teams were large. Organizations had dozens of programmers on sprawling projects. Reusing code was not trivial. SharingContinue...Daniel Lemire From Daniel Lemire's Blog | June 27, 2025 at 09:33 AM
In North America, my home province of Quebec has a slightly higher life expectancy than the rest of the country. It is also a poorer-than-average province, so that...Daniel Lemire From Daniel Lemire's Blog | June 20, 2025 at 08:32 PM
There is an extremely naive model of science and innovation called the linear model: The model postulated that innovation starts with basic research, is followed...Daniel Lemire From Daniel Lemire's Blog | June 12, 2025 at 10:33 AM
We often need to quickly classify characters. For example, consider how the binary data that you send by email is converted to an ASCII string made of 64 distinct...Daniel Lemire From Daniel Lemire's Blog | May 31, 2025 at 11:32 PM
Concerns persist that artificial intelligence (AI) could render software developers obsolete, particularly with tools like GitHub Copilot and Cursor streamlining...Daniel Lemire From Daniel Lemire's Blog | May 27, 2025 at 05:34 PM
The ancient Greeks crafted extraordinary models that continue to resonate. For instance, Ptolemy’s geocentric model, with Earth at the core and planets tracingContinue...Daniel Lemire From Daniel Lemire's Blog | May 23, 2025 at 07:38 PM
Suppose that you have an array of N elements and you want to divide it into M chunks. It is a common task when trying to spread N units of work over M threads,Continue...Daniel Lemire From Daniel Lemire's Blog | May 22, 2025 at 01:40 PM
Many programming languages such as the Go programming language are designed to make it easy to return several values at once from a function. In Go, it is often...Daniel Lemire From Daniel Lemire's Blog | May 18, 2025 at 04:22 PM
A few weeks ago, I attended a software engineering seminar focused on the role of large language models in programming. The distinguished software engineering professors...Daniel Lemire From Daniel Lemire's Blog | May 10, 2025 at 04:54 PM
In C++, templates enable generic programming by allowing functions and classes to operate on different data types without sacrificing type safety. Defined using...Daniel Lemire From Daniel Lemire's Blog | May 3, 2025 at 03:44 PM
In software, we often use key-value data structures, where each key is unique and maps to a specific value. Common examples include dictionaries in Python, hash...Daniel Lemire From Daniel Lemire's Blog | April 20, 2025 at 04:40 PM
It is often puzzling to encounter organizations run by highly capable and ambitious people… appear dysfunctional. An example that I like are colleges that claim...Daniel Lemire From Daniel Lemire's Blog | April 11, 2025 at 02:56 PM
Do large language models (AI) make you 3x faster or only 3% faster? The answer depends on the quality of the work you are producing. If you need something likeContinue...Daniel Lemire From Daniel Lemire's Blog | April 7, 2025 at 03:41 PM
Random integer generation is a fundamental operation in programming, often used in tasks like shuffling arrays. Go’s standard library provides convenient toolsContinue...Daniel Lemire From Daniel Lemire's Blog | April 6, 2025 at 04:26 PM
Most mobile devices use 64-bit ARM processors. A growing number of servers (Amazon, Microsoft) also use 64-bit ARM processors. These processors have special instructions...Daniel Lemire From Daniel Lemire's Blog | March 28, 2025 at 09:44 PM
There are two main types of fixed-precision integers in modern software: unsigned and signed. In C++20 and above, the signed integers must use the two’s complement...Daniel Lemire From Daniel Lemire's Blog | March 24, 2025 at 07:24 PM
