I trained myself to run farther using the Strava API and an IOT dog food bowl full of M&Ms Published: 2024-12-01 | Origin: /r/programming The author describes a creative approach to motivating themselves to run by using an IoT dog food dispenser filled with M&Ms as a reward system tied to their running distance monitored via the Strava API. This system proved to be highly effective, leading the author to regularly run long distances and even complete a half marathon, eventually moving on from the dispenser's rewards. Reflecting on adulthood, the author expresses a newfound understanding that adulthood involves juggling a myriad of maintenance tasks rather than simply knowing the date. This |
Education and Healthcare Suck for the Same Reasons Published: 2024-12-01 | Origin: Hacker News The content discusses the detrimental effects of an overemphasis on measurable outcomes in both healthcare and education. It begins with a morning scene in a hospital where a patient’s needs are overlooked amidst routine medical measurements, drawing a parallel to a classroom where a teacher focuses solely on standardized test scores, neglecting the individual students. This highlights a broader issue: systems are prioritizing metrics over the human experience. While acknowledging the value of measurements in both fields—advancements in medical technology and educational assessments—the article |

Ntfs2btrfs does in-place conversion of NTFS filesystem to the open-source Btrfs Published: 2024-11-30 | Origin: Hacker News The content discusses the tool **ntfs2btrfs**, which allows for in-place conversion of Microsoft's NTFS filesystem to the open-source Btrfs filesystem, similar to how **btrfs-convert** works for ext2. The tool saves the original image as a reflink copy at **image/ntfs.img**, and users can delete this if they want to free up space after conversion. While the tool is considered stable, the author assumes no responsibility for any issues that may arise |
AMD Disables Zen 4's Loop Buffer Published: 2024-11-30 | Origin: Hacker News A loop buffer is utilized in a CPU's frontend to store a limited number of previously fetched instructions, allowing for the execution of small loops while conserving power and enhancing performance by bypassing certain frontend limitations. This technique has been employed by major chip makers like Intel, Arm, and AMD. Notably, AMD's Zen 4 is the only high-performance core from AMD that incorporates a loop buffer, which is referenced as a micro-op dispatch source in its documentation, with a capacity of 144 entries, |
Learnings after 4 years working with 50+ companies on data engineering projects Published: 2024-11-30 | Origin: /r/programming In the first four years of founding Tinybird, the author has focused on assisting over 100 companies with their technical needs, with hands-on support for more than 50, ranging from small businesses to large enterprises. Tinybird addresses various projects, often involving the optimization of existing systems to achieve real-time processing capabilities, leading to significant cost savings for clients. The author clarifies that 'real-time' processing does not necessarily mean using complex technologies like Kafka or Spark, but rather achieving faster data processing |
Concurrency diagrams Published: 2024-11-30 | Origin: /r/programming The article discusses the common misunderstandings engineers face regarding concurrency in program design and system architecture. These misunderstandings often arise from differing internal assumptions about how concurrent processes function, which can remain unnoticed until they become costly to fix later in development. To mitigate this, the author suggests using concurrency diagrams, which visually represent the system's components and their interactions over time. These diagrams help clarify assumptions and can even alter the creator's perspective on system sequencing. Time is plotted along the vertical axis, while functional components are |
Django and Postgres for the Busy Rails Developer Published: 2024-11-30 | Origin: /r/programming The author, a software engineer, consultant, and author, reflects on their experience transitioning from MySQL to PostgreSQL and recently working with Python, Django, and PostgreSQL after being a long-time Rails developer. They note their curiosity about Django due to their experienced team and plan to share insights on Django's database components, relevant libraries, tools, and a comparison with Ruby on Rails.

A dead simple command line journal (encrypted entries & almost no dependencies) Published: 2024-11-30 | Origin: /r/programming The content outlines a command line journaling system designed to be minimal and easy to set up across multiple UNIX devices, using just two bash scripts. Inspired by the jrnl project, it emphasizes encrypted file storage using symmetric AES256 encryption with GPG. The setup process prompts users for a password, creates a structured folder system based on ISO 8601 time and date formats, and generates a hidden directory (.jrnl/) in the user's home directory to hold the main script and environment variables. Users can |
On Histograms in Decision Making Published: 2024-11-30 | Origin: /r/programming In a meeting discussing a feature design, a designer inquires about the expected number of values in a dropdown, to which a database analyst responds with an average of six. However, upon implementation, the dropdown contains over a thousand options. This situation highlights the limitations of relying solely on averages, especially when outliers exist. Outliers can significantly skew averages, making them misleading. To better understand data distribution, the analyst suggests using standard deviation, which indicates how spread out the data is. A low standard |
How to Implement Undo/Redo for a Half-Edge Data Structure? Published: 2024-11-30 | Origin: /r/programming The author reflects on the complexity of implementing undo/redo functionality for a half-edge data structure while reviewing code. They emphasize the varying approaches programmers take, balancing development costs with the efficiency of solutions. The standard pattern involves two virtual functions: `undo` and `redo`, where `redo` executes a command and saves the state of the object before the operation, while `undo` restores the previous state. The discussion then shifts to the specifics of the flip operation, which changes the orientation of an edge |
Thoughts on the Software Industry Published: 2024-11-30 | Origin: Hacker News In an email, the author reflects on their thoughts about the software engineering field, particularly for newcomers. They draw parallels between mathematics and software, describing mathematics as a toolbox of abstractions that can provide various perspectives on problems. Similarly, they view software as a set of tools for solving issues with computers, which eventually leads to its own vocabulary and worldview. This "software's worldview" focuses on abstractions related to system complexities, signal vs. noise, and information management. The author argues that understanding software |
Engineering Sleep Published: 2024-11-30 | Origin: Hacker News The content discusses the importance of sleep, which constitutes a third of human life and is essential for various bodily systems. It poses the question of whether it is possible to reduce sleep duration while still feeling refreshed, drawing on examples of individuals with Familial Natural Short Sleep (FNSS) mutations. FNSS allows some people to sleep 1-2 hours less than the recommended 7-9 hours without adverse effects, making them healthier and more energetic. Research has identified five genes associated with FNSS, |
