A developer has launched CertWorthIt, a web tool designed to help people decide whether a professional certification is worth pursuing. The platform analyzes job postings to reveal which certifications employers mention most often. Users can compare different certificates side by side and explore how demand varies across countries. The creator built the tool because many certification options exist with little clear information about employer expectations. The developer has invited feedback from the community on the project.
A developer describes getting frustrated that PDF password-removal sites required uploading sensitive bank statements to their servers. The article explains the two types of PDF passwords: open passwords that block viewing, and owner passwords that only restrict printing or copying. It notes that removing an open password requires knowing it, and warns that sites offering to remove unknown passwords are merely guessing and may waste the user's file. Built-in alternatives include printing the PDF to a new file in Chrome, Edge, or Preview on a Mac, along with trade-offs like possible loss of links or bookmarks. The author also recommends the command-line tool qpdf for a cleaner decryption without re-rendering, and mentions a browser-based option that processes files locally.
A software engineer who built three personal apps, a virtual-pet step tracker, a receipt scanner, and a weather-based outfit app, found that none attracted significant users. He had spent most of his effort on development and little on getting people to try the products. Now he uses AI coding tools to build faster, but he notes that quicker development makes it easier to start new projects without solving the distribution problem. His fourth project, ZaneShot, is a macOS screenshot and screen recording app that he built largely with AI assistance. He acknowledges that other screenshot tools already exist on the platform.
KingKong Robotics has open-sourced Jumper, a 22-degree-of-freedom crab robot, and is running a challenge from September 30 to November 30, 2026 that will award 100 physical units to outstanding open-source projects. Entries are short videos posted on X or YouTube with specified hashtags, judged 60% on audience response and 40% on expert review across appearance, playfulness and usefulness. The author is producing simulation footage using the robot's published specifications and the toolkit's trained policies, with an emphasis on concept and presentation over physics accuracy. Originality and music licensing are strict requirements, so the soundtrack is generated with an Apache-2.0 model. The project has progressed through toolkit setup, rendering fixes and scene design built at a diorama scale suited to the robot's 13 cm height.
