SQLite has a new feature called generated columns, allowing JSON data to be inserted and indexed like a document database. This enables treating SQLite as an embedded document database for lightweight applications.
The author transitioned to Linux and found Continuity features from macOS lacking, particularly OTP code autofill. Tether aims to replicate these features on Linux, initially focusing on clipboard sync before expanding to other areas.
SLEEPWALKER is a passive backdoor that activates when the host process carries the name ERAAgent.exe, and it never contacts a fixed C2 address. It uses six transports including DNS triggering, VMCI, ICMP, named pipes and TCP/UDP connections to deliver commands over the network. The malware has 23 instructions covering scheduling, staged file delivery with SHA-256 verification and in-memory execution.
The user discussed a hack to support older versions of GCC by using trampolines and the __builtin_call_with_static_chain built-in function. This allows calling nested functions without requiring an executable stack, addressing security concerns.
A tool called Typebase-io-cli helps create a fully typed server with database schema, actions, and auth in a single folder, allowing for explicit authorization and backend functions that live in code. It enables developers to deploy their server on various platforms without owning any servers.
Glacier mice are colonies of mosses and other organisms found on glaciers, with movement patterns that appear to be herd-like behavior. They can persist for six years or longer, creating a suitable ecosystem for microorganisms on the glacier surface.
Samsung's LPDDR5X-PIM technology enables in-memory compute by implementing MAC units within LPDDR5X chips, allowing for high-bandwidth processing. This approach can achieve significant performance gains compared to standard LPDDR5X, but poses challenges for software due to mode switching and cache coherency issues.
Colours can be precisely quantified using numbers, with the LMS colour space representing all perceivable colours. However, this is not the standard way to describe colours, and instead RGB values are commonly used. The CIE XYZ colour space uses standardized primaries that are imaginary and do not correspond to physical quantities. Chromaticity spaces like xy chromaticity provide a convenient ...
A Hacker News post debated the merits of terminal user interfaces (TUIs) versus graphical user interfaces (GUIs), with some arguing TUIs are preferable due to keyboard navigation capabilities, but this argument lacks solid foundation. Implementing full keyboard navigation in GUI applications can improve user experience and should not be ignored by developers.
Roman space telescope launches on August 30, 2026 at 07:26 am EDT on a SpaceX Falcon Heavy rocket. The observatory was built by technicians after NASA's Nancy Grace Roman Space Telescope project.
The author, an engineer, created a seamless ambiance experience from a 7-minute video by extracting the audio assets and using the Web Audio API to recreate them. They used plugins like SoundFilter to identify the desired asset and then processed it with JavaScript code.
We have a partial port of GrapheneOS to the Pixel 11 series after a week of work on it. We're unable to complete the port due to lack of support for ARM hardware memory tagging in software, firmware and near certainly hardware. It appears Google cut an important security feature to save money.
EVE Online is transitioning from Python 2 to Python 3, aiming for a completely unnoticeable change. The first stage of the migration has been deployed on Tranquility, with further updates and testing planned in the coming months.
This tool creates a virtualized iOS environment for testing and development, allowing users to download, patch, and restore iOS images. It also provides features like automatic provisioning, E2E testing capabilities and host control through a socket.
Debian's general-resolution vote on generative AI tools resulted in choice 5: Responsible Use of Generative AI being the winner. The project acknowledges that such tools can improve productivity but still expects contributors to review and test their output before submission.
The htmx team has released version 4.0.0, marking the culmination of 8 months of work after adopting fetch() API and async programming in JavaScript. The new release includes significant changes such as explicit attribute inheritance, standardized event names, and improved history support without localStorage usage by default.
A Go application crashed on a 32-bit ARM embedded Linux system due to an internal assumption in the netpoll mechanism, which expected EPOLLIN as the only firing event. The issue was resolved by changing how netpoll tells event fds and socket fds apart, removing aliasing between raw pointers and tagged pointers.
Explore the universe in 3D: fly from Earth to planets, stars, nebulae and distant galaxies, right in your browser.
In short: Vim has a joke autocmd called UserGettingBored that doesn’t do anything. Vim’s automatic commands feature, usually shortened to “autocmd”, lets you run code when various events occur. For example, you could implement an auto-save feature by binding the TextChanged event to the :w command. Vim has over 100 events, from “buffer was created” to “file was saved”. But one of them sticks ...
A/I is an autonomous anticapitalist movement providing free digital self-defense tools and services for activists, focusing on solidarity and non-commercial use. All services are provided without data commoditization or compensation, with manual review by volunteers to ensure alignment with their principles.
StemDeck is a free, open-source audio stem separation tool that processes existing audio files locally on your machine. It separates up to six stems (vocals, drums, bass, guitar, piano, other) from uploaded or pasted audio files.
Pociąg Pt47-65 w okresie od 20 sierpnia do 28 sierpnia prowadzony będzie przez SM42 6D. Bilety dostępne na stronie www.koleje-wielkopolskie.com.pl.
The author created a Datalog engine for LLMs to improve their memory and reduce hallucinations during vulnerability research. The system allows the model to maintain its analysis state, track dependencies, and invalidate conclusions when new information is discovered.
This document explains the time complexity of various operations on built-in types in CPython, with Big O notation describing how running time grows with input size. The costs assume exact built-in types and account for resizing and collisions.
Orbify Demo 2 v72 — interactive Gaussian-splat navigation visualization.
The author emphasizes that a great culture is more important than AI tools for increasing productivity, as it affects how people work together and communicate. A good culture can amplify the benefits of AI, but bad culture can hinder its effectiveness.
TurboKV is an async embedded key-value database with atomic batches and configurable durability, compression, and background compaction. It provides a Rust API for opening databases, inserting data, scanning keys, writing batches, and closing the database.
The author released a security fix for OCaml's cohttp 6.3.0, but noticed probes in live webserver logs with the exact bug pattern just minutes after opening the PR to fix it, indicating automated exploit generation is now possible within seconds. The traditional security process needs to be inverted to prioritize private patch development and rapid release over secrecy of details.
The author released posuto, a package presenting Japanese postal code data in an easy-to-use format, after encountering issues with the original CSV file from Japan Post. The CSV has various formatting problems and inconsistencies that make it difficult to parse.
Icelanders vote on whether to resume EU accession talks, with a tight result expected. The debate centers around the country's sovereignty and fishing industry, with some fearing loss of control over waters under EU rules.
