Free DDNS with Cloudflare and a Cronjob

The GitHub repository "devrim/cloudflare-noip" offers a free alternative to paid dynamic DNS services like NoIP.com, allowing users to automatically update DNS records on Cloudflare. Users need to set up a cron job or similar scheduled task to run a Python script that updates their DNS records with the current IP address at specified intervals. The setup requires creating a configuration file with Cloudflare API details and a records JSON file for DNS settings.

Oscar Zariski was one of the founders of modern algebraic geometry

Oscar Zariski, a significant figure in modern algebraic geometry, was known for his deep passion for mathematics, evident even on his wedding day when he became engrossed in solving a problem and arrived late. His early life was influenced by his brother, Moses, who nurtured his mathematical interests, while Zariski\'s encounter with the rich mathematical culture in Italy highlighted the importance of the Italian School in algebraic geometry. Despite his late start in publishing, Zariski remained active in his field until his eighties, exemplifying the dedication of many mathematicians of his era.

Bashsimplecurses: Simple curses library made in bash to draw terminal interfaces

The Bash Simple Curses library is designed to create terminal interfaces and draw colored windows in Bash scripts. Users can import the library, define a main function to create windows and display text, and execute a loop to update the interface. Installation options include copying the library to a project directory or installing it system-wide with `make install`.

Learning about PCI-e: Driver and DMA

The article discusses the implementation of a PCI-e device driver that allows interaction with the hardware through memory mapping and character device interfaces, focusing on reading and writing data using direct memory access (DMA). It highlights how to set up the driver to expose a character device to user space, facilitating efficient data transfers by allowing the device to handle copying rather than relying on CPU resources, and introduces message signaled interrupts (MSIs) for notifying completion of asynchronous DMA operations. The author demonstrates the steps for creating a framebuffer in a virtual GPU environment using QEMU, enabling visual output based on user-space write operations.

Adobe exec compared Creative Cloud cancellation fees to \'heroin\'

An Adobe executive compared the company\'s early termination fees for Creative Cloud subscriptions to "heroin," as detailed in a newly unredacted FTC complaint alleging deceptive practices regarding hidden fees and complicated cancellation processes. Adobe\'s general counsel, Dana Rao, refuted the claims, stating that the fees contribute minimally to revenue and that the company has been making changes to its cancellation practices since 2021 based on consumer feedback. He also noted that recent legal rulings could allow Adobe to argue that its cancellation flow is simple, despite the FTC\'s concerns about consumer understanding of termination fees.
