Calculus has two main branches: differential calculus, which calculates the slope of a function, and integral calculus, which calculates the area under a curve. The two are connected by the Fundamental Theorem of Calculus, which states that integrals are anti-derivatives, but integral calculus is generally harder than differential calculus due to its global nature.
The user discovered a severe vulnerability in MSI Center, a pre-installed software on MSI laptops and desktops, allowing for Remote Code Execution (RCE) with valid login credentials. MSI patched the vulnerability within two days and the user is still waiting for a CVE from VulDB after submitting their report.
Steam Controller Auto-Charge is an open-source app that automatically charges a Steam Controller using computer vision and WebHID telemetry. It uses optical flow tracking, haptic navigation, and battery status polling to guide the controller to its charging puck.
Learning new things is fun and makes life richer, but it requires a daily time investment of up to an hour. It's a long journey with initial struggles, but consistent practice leads to improvements over time.
SearXNG is a free internet metasearch engine which aggregates results from various search services and databases. Users are neither tracked nor profiled. - searxng/searxng
The user investigated why memory usage reported by fastfetch and btop differed on FreeBSD, discovering that the discrepancy was due to btop's incorrect handling of the ARC cache and filesystem metadata buffer cache. The user contributed patches to btop and htop to improve their memory usage reporting, and also submitted a PR to fastfetch, which was later merged with improvements.
Amsterdam's fire-fighting system improved in the 17th century with the introduction of new engines and a culture of inventiveness. The city's fire damage decreased dramatically after implementing the Van der Heyden brothers' suction and pressure hoses.
User has $2k to spend on local machine intelligence and $40k for top-of-the-line. They have 4x RTX Pro 6000s and built a DDR4 system to host them.
GingerBill, the creator of the Odin programming language, expressed concerns about Wikipedia's deletion of the Odin article due to lack of reliable sources, but his tone shifted from dismissive to concerned after Casey Muratori, a famous videogame programmer, pointed out the flaws in Wikipedia's notability rules for programming languages. Casey argued that Wikipedia's rules prioritize ...
The author, a co-founder of Databricks, discusses how traditional OLTP databases are clunky, difficult to scale, and fragile, and proposes a new architecture called Lakebase that externalizes storage and compute, making databases more durable, elastic, and cheaper to run. Lakebase's design also enables a new feature called LTAP, which unifies transactional and analytical workloads by storing ...
The user discusses the importance of threat modeling in cybersecurity, explaining that it's a formal process that helps identify potential threats and vulnerabilities in a system, and provides a framework for understanding assumptions and accepted risks. They also apply threat modeling to real-world examples, including hybrid post-quantum cryptography and end-to-end encrypted messaging apps, ...
Anthropic and OpenAI announced efforts to use frontier models for cybersecurity, but this led to a significant increase in high-severity vulnerabilities. The number of high- and critical-severity CVEs jumped 3.5x in June after the announcements.
The author taught project-based programming courses from 2007-2023 but had to stop due to a collapse in the continuing education market. They're now pursuing a Professional Educator's License in Secondary Education.
cardiag is a proof-of-concept audio-ML pipeline for car fault diagnosis from phone recordings. It provides a calibrated triage aid with honest uncertainty, isolating mechanical sounds and ranking likely parts.
Ruby is used for reverse-engineering a binary file format, specifically Codemasters' BIGF archive format, with its standard library providing a fast and efficient binary parser. The parser uses String#unpack and Ruby strings as byte buffers to decode the binary data, making it a pleasant and effective collaboration with an AI.
Amazon's complex logistics model may not be the most efficient or socially beneficial, while Costco's simpler model offers lower costs and better worker treatment. A public grocery store model, inspired by Costco and the military commissary system, could provide cheaper groceries for New Yorkers with lower overhead.
This is a course based on Fong and Spivak's book Seven Sketches in Compositionality: An Invitation to Applied Category Theory, taught by John Baez and turned into nice webpages by Simon Burton. © 2018 John Baez
The Pew Research Center study found that 38% of webpages from 2013 are no longer accessible, but the Wayback Machine has rescued roughly 15% of those dead pages. Web archives like the Wayback Machine play an increasingly important role in rescuing the dead Web and minimizing the fracture of the knowledge graph on the Web.
You spoke to a year group about manufacturing, sharing your experience making an AI clock and showing them various stages of design and production. You aim to normalize hands-on learning and inspire kids to become makers and inventors.
Stelios Kouloglou, a former European Parliament member, was hacked with NSO Group's Pegasus spyware twice, in October 2022 and March 2023, while investigating spyware abuses. The infections likely captured non-public information about committee activities, breaching EU parliamentary confidentiality.

SQLite fixed a long-standing bug in WAL checkpointing that could lead to database corruption. The dqlite team used TLA+ to model SQLite's behavior and found that dqlite is not affected by the bug due to its stricter locking mechanism.
LAWRENCE — New research from the University of Kansas uses network science to determine why people make mistakes when lip reading. Michael Vitevitch, professor of speech-language-hearing at KU, and his co-authors created a visual map of around 20,000 words in English, hoping to better grasp why some words are more difficult to lip-read than others. The results appear in the Journal of the ...
