Git worktrees allow working on a project in two folders with shared history, reducing maintenance compared to separate clones. Jujutsu's "workspaces" feature simplifies working with worktrees, enabling easy management of multiple folders within a repository.
GitHub Actions lacks a fundamental security feature, the lockfile, which could prevent silent changes to workflow dependencies and provide reproducibility. The lack of lockfiles, integrity checks, and transitive dependency visibility makes GitHub Actions vulnerable to supply chain security attacks and is a major concern for software security.
The New DSL 2024 is a compact Linux distribution for low-spec x86 computers, packing many applications into a 700MB package. It's based on antiX 23 i386 and aims to keep older computers useful by providing a usable desktop within a small size limit.
The user uses a virtual machine with a minimal Ubuntu Server installation and runs Emacs as their window manager to keep a clear division between work and personal life. They customize Emacs to utilize every pixel, embed a text-oriented browser, and use a function to organize windows for ultimate distraction, making it their entire Linux desktop.
The user attempted to recreate the 1996 Space Jam website using Claude, a language model, but despite various tools and prompts, Claude failed to accurately recreate the website's layout due to limitations in spatial reasoning and precision. The user hypothesized that Claude's vision encoder converts images into semantic tokens, making it difficult for him to work with visual media and ...
lockenv is a tool for securely storing sensitive files in an encrypted vault. It uses a password-derived key for encryption and can be used with various shells and operating systems.
The author suggests that we should stop personifying AI and instead view it as a "bag of words" that contains all the words ever written, which can be used to generate responses to user queries. This metaphor can help us understand AI's capabilities and limitations, and prevent us from making incorrect assumptions about its intelligence and intentions.
Archaeologists are resuming digs at the Ness of Brodgar after 3D radar technology revealed an extraordinary discovery. The find is unlike anything else at the site and may not even be Neolithic, with further excavation planned for July 2026.
A design agency was hired to redesign a service company's website. The client wanted a contact page that made it hard for users to contact them, which was not suitable for their service-based business.
ReadyKit is the fastest way to ship a SaaS-ready Flask product with billing, authentication, and workspaces built in.
A state government inspector found that Family Dollar and Dollar General stores in North Carolina and other states had a high error rate in pricing accuracy, with some stores failing multiple inspections. The issue is attributed to understaffing, overstocking, and a lack of incentives for retailers to correct the problem, affecting low-income customers who rely on these stores for affordable ...

truemetrics is a Berlin-based startup that helps last-mile delivery companies navigate cities more efficiently. They're looking for a skilled Python developer to join their team and contribute to mapping and positioning technology.
Researchers at Google introduced Titans, a new sequence modeling architecture that combines the speed of RNNs with the accuracy of transformers. Titans uses a deep neural network as a memory module to learn and update its parameters in real-time, enabling it to handle extremely long contexts.
Researchers developed a Stirling engine that generates mechanical power from Earth's ambient radiation. The engine uses radiative cooling to create a temperature difference between the engine plates, resulting in a power output of 400 mW/m2.

The Fourier Transform breaks down a signal into its underlying cycles, like a smoothie recipe breaking down ingredients. It finds the speed, amplitude, and phase of each cycle to recreate the original signal.
The user created a complete database of every "interesting" starting position for the Rush Hour puzzle, which includes 2,577,412 puzzles covering 9,698,093,879 reachable states, and made the database available for download. The user's code uses bitboards, simulated annealing, and other techniques to efficiently generate and analyze the puzzles, and the user estimates that solving the 7x7 case ...
Einstein officially runs on macOS, iOS, and Ubuntu Linux with partial support for Android, Raspberry Pi, and Windows. A Newton ROM file is required to run Einstein. We cannot distribute the ROM file. If you own a Newton device, you may be able to dump your own ROM file from it. See Dumping The Rom for more information.
Mac OS X introduced a bundle structure for applications, consisting of a hierarchy of directories containing executable code and resources, with a standard form including a MacOS directory, Resources, and Info.plist file. The bundle structure has evolved over the years to include additional components such as code signatures, notarization, and store receipts, providing improved security and ...
CATL aims to provide zero-carbon marine transportation with electric ships navigating open seas within three years. The company has supplied batteries for over 900 vessels and is collaborating with shipping partners to advance electric shipping.
Calling a function with the wrong signature can lead to unexpected consequences, such as a STATUS_REG_NAT_CONSUMPTION exception on the ia64 architecture. This is because the ia64 has a "NaT" bit that gets set when a register does not contain a valid value, which can cause problems when trying to save or access the register's value.
To block ads, consider using browser extensions like uBlock Origin and DNS filtering with Pi-hole or AdGuard Home. Additionally, routing traffic through a cloud provider via VPN can also help reduce ad visibility.
The author migrated a service from Scala 2.13 to 3.7.3, but performance issues arose due to a library bug affecting chained evaluations. Upgrading the library resolved the issue, highlighting the importance of benchmarking in Scala version migrations.
Anubis is a server protection system using Proof-of-Work to prevent aggressive website scraping. It may cause downtime but is a temporary solution to be replaced by more advanced browser fingerprinting methods.
Researchers introduced Nested Learning, a new approach to machine learning that bridges the gap between model architecture and optimization algorithm. This paradigm treats a model as a system of interconnected, multi-level learning problems optimized simultaneously, enabling more capable and efficient learning algorithms.
A group of friends created a method to generate random numbers using a polar coordinate system and a clock face, which they used to play a simplified D&D campaign. They also designed a game called verbal tennis where players use their generated numbers to hit a virtual ball, with the goal of winning the game.
