TL;DR summary of stories on the internet
The author shares eight practices they adopted while building an in-memory cache, focusing on efficiency, simplicity, and reliability. They emphasize using off-the-shelf solutions whenever possible, prioritizing cost and reliability over features, moving quickly from idea to production to determine necessary features, utilizing simple data structures to avoid performance issues, reserving resources early to prevent late […]

How often do your prototypes or scripts turn into full applications? The simplicity of code growth can lead to maintenance issues, particularly with dicts as primary data structures. Modern Python offers alternatives to plain dicts, which can be problematic. Dicts create challenges in extending functions and manipulating data, leading to tech debt. To address this, […]
DigitalOcean offers cloud products for all stages of your journey, kicking things off with $200 in free credit. Lea Verou had a clever idea to use an emoji as a favicon, now possible with browser support for SVG. Chuck an emoji inside an SVG element and use it as your favicon with a simple one-liner […]
The author revisits coding from scratch like homemade pasta, recalling fond memories of toys built by their father. The game engine, written in C++17, and games in Lua, utilizes lazy asset prefetching to optimize performance. Resource management is crucial, with an object pool limit for bullets on the screen. The game, scripted in Lua, features […]

Time is often represented as a coordinate, but what is it intrinsically? Thinking in computational terms reveals that time is the progressive doing of computation by the universe, due to computational irreducibility. This implies that time cannot be jumped ahead in; one must go through each irreducible computational step to reach the future. Our experience […]
Squey is an open-source visualization software that helps users explore and understand large amounts of tabular data. It can assess data quality by detecting invalid rows and missing values, combine visualizations to reveal patterns and anomalies, and conduct investigations to detect weak signals. With the ability to work with various datasets, Squey is used in […]
Canon is confident that their nanoimprint technology can complement existing EUV technology in the semiconductor industry, starting with 3D Nand memory chips. However, analysts doubt the impact it will have, stating that nanoimprint is not a superior technology. Canon aims to achieve greater miniaturization levels, starting at 5nm and targeting 2nm. Achieving a high yield […]
A new way to build apps with distributed state using Collaborative Values (CoValues), based on CRDTs and public-key cryptography. CoValues are editable like local JSON, automatically synced and persisted, and keep full edit history. They include data structures like CoMap and CoList, with plans for CoPlainText, CoRichText, and more. Secure permissions and team roles are […]
In his insightful essay, the author discusses the famous quote by Brian Kernighan about the challenges of debugging compared to writing code. While some interpret the quote as a warning against clever code, the author argues that cleverness is a dynamic skill that can be cultivated through practice. The concept of flow is introduced, highlighting […]
