The blog post humorously outlines strategies for sabotaging teamwork based on "The 5 Dysfunctions of a Team." It emphasizes how to exploit each dysfunction to advance personal goals at the expense of effective team dynamics. The first dysfunction discussed is Trust. It suggests that trust is foundational for team success, and encourages actions that undermine it: - Discourage vulnerability by making colleagues uncomfortable when they share failures. - Withhold transparency by avoiding data-sharing and hiding bad news to keep the team in the dark

FastRuby.io provides specialized services for upgrading, maintaining, and managing technical debt in Rails applications. Before upgrading, they recommend conducting a "Roadmap to Upgrade Rails," which is a static code analysis that helps outline an action plan and provides time and cost estimates for the upgrade. As part of their upgrade process, they focus on addressing deprecation warnings. They recently began extracting these warnings from Rails versions 2.3 through 7.1 to assist in their static analysis. They first needed to

The feedback from the community is highly valued, and contributors are encouraged to engage with the maintainers on GitHub. A member of Apple's visionOS engineering team expresses eagerness to support the Godot engine by contributing visionOS capabilities. They have prepared an initial pull request (PR) to lay the groundwork for this support, adhering to Godot's coding standards and aiming to align their contributions with the project's goals. The team acknowledges that while they have divided their work into smaller PRs, some may

The content discusses the control bits and state machine of TCP, fundamental for understanding its three-way handshake process. TCP control bits manage the connection's status, indicating actions like establishment and termination. There are six main control bits, and since TCP is bidirectional, each side maintains its own sequence (Seq) field. The Seq numbers are dynamically generated to enhance security against attacks such as forged reset packets. TCP ensures ordered data transmission, requiring each segment to include a Seq number. The Seq number for the next

The proposal highlights the lack of transparency and explicit permission requests in the management of software libraries and gems, contrasting it with the Android Manifest permission system, which ensures users review permissions before app installation. It suggests that just as Android apps must declare their resource access, Ruby gems should also have a manifest system to define and limit permissions explicitly. This would enhance security awareness, improve access controls, and maintain developer experience. The proposal envisions a bundler-level manifest that specifies network permissions, such as allowed hosts and

Dr. Maltz, a plastic surgeon, made an observation regarding habit formation that was misinterpreted as a definitive fact. The widely cited idea that it takes 21 days to form a habit is misleading; instead, a study published in the European Journal of Social Psychology by Phillippa Lally and colleagues found that forming a new habit typically takes between 2 to 8 months, with an average of 66 days. The time required varies based on the habit, the individual, and their circumstances

The content discusses various methods to implement a macro in C that takes an expression as an argument while addressing challenges related to determining if an expression is constant. The solutions differ based on the C standard in use and the allowance of compiler extensions. 1. **C23 and Later**: You can use compound literals with `typeof` to store expressions, leveraging the requirement that static storage duration initializers be constant expressions, which helps ensure the expression is constant. 2. **GNU Extensions**: The `__

The content discusses bloom filters, a space-efficient, probabilistic data structure used to check for set membership. Unlike traditional hashmaps, which store every user request, bloom filters can quickly determine if a user has likely visited a page before, using significantly less memory and eliminating false negatives. However, they may yield false positives, meaning they can indicate an element might be in the set even if it's not. The document will compare bloom filters to hashmaps, which utilize a hash function to store key-value pairs

ClickHouse, a fast analytical database, has implemented a new optimization called lazy materialization, which enhances its query performance by delaying the reading of column data until it is actually needed. This approach significantly reduces unnecessary work and speeds up query execution, especially for Top N queries with LIMIT clauses, which are common in analytics. For instance, a specific ClickHouse query showcased a dramatic speed improvement from 219 seconds to just 139 milliseconds—achieving a 1,576× speedup—simply by

The blog post discusses the mathematical rigor necessary for programming languages, focusing specifically on the less-defined semantics of machine knitting. Machine knitting involves programming to control arrays of needles to manipulate yarn into 3D objects. The author explores the importance of establishing clear semantics for machine knitting, explaining their potential applications in error checking, code optimization, and transformation, much like traditional programming languages. To illustrate the significance of semantics, the author presents a "commuting" problem: determining whether the order of two statements in a
