Engineers are hopeful that Voyager 1 is making progress after sending a “poke” command to its Flight Data System, potentially bypassing corruption. The spacecraft, which has outlasted expectations, recently sent a complete memory dump, containing code and data variables. Dr. Suzanne Dodd noted that the data was not as expected, but showed the FDS was […]
PyKidos is a tool developed by Cyrille Rossant that allows you to store your code locally in your browser’s local storage. Your information is never sent to any external server, ensuring privacy and security. One unique feature is the ability to easily backup your data using the Download button. You can find the source code […]
The author shares their journey of successfully reverse engineering and replaying a car’s key fob signal using an RTL-SDR dongle. They explain the basics of radio frequency, modulation, and bandwidth, emphasizing the importance of the hardware and software tools used for analysis. By using the Universal Radio Hacker software, the author decodes and analyzes the […]
Peter Schweitzer, a theoretical physicist, has spent his career exploring the energy-momentum tensor of the proton, essential for understanding its properties. In the 1960s, it seemed impossible to uncover this tensor without graviton scattering, which is practically undetectable due to gravity’s extreme weakness. However, recent research by Xiangdong Ji and Maxim Polyakov revealed a way […]
Skyvern automates browser-based workflows by using LLMs and computer vision, offering an API for automating manual tasks on various websites without the need for custom scripts. This approach allows Skyvern to operate on new websites, adapt to layout changes, and apply the same workflow to multiple sites. Leveraging LLMs enables Skyvern to handle complex scenarios, […]
Czech author Jaroslav Hašek’s most famous work, “The Good Soldier Švejk,” satirizes bureaucracy, the military, and war during World War I. The antihero, Josef Švejk, blunders from one ludicrous adventure to another while earnestly trying to follow orders to extreme lengths. Hašek, who led a colorful life, planned to write the Švejk story in six […]
Veryl is a modern hardware description language positioned as a “SystemVerilog Alternative.” It offers simplified syntax, SystemVerilog/Rust-based design, and removes traditional Verilog syntax. Notably, it transpiles to SystemVerilog, generates readable code, and promotes interoperability with SystemVerilog. The language boasts integrated tools like a formatter and linter, with support for VSCode and vim/neovim. Veryl allows for […]
The author takes a nostalgic trip back to 1981, recalling a friend with an Apple II+ and programming lessons with “Mrs. Cathy.” Their interest in reverse engineering the Lemonade Stand game led to an attempt to maximize profit through Python code, highlighting the significant increase in computational speed over the years. Playing the game online […]
If you enjoy the article, the author has published a book explaining Git internals: Building Git. As a programmer, you use version control systems like Git, spending time looking at diffs. Diffs allow you to check uncommitted work, compare branches, and more. They’re read by people but also used by version control systems for automation. […]
