• Hackaday ☛ Gilbert Cell Lacks Sullivan

  If you’ve ever used an NE602 or similar IC to build a radio, you might have noticed that the datasheet has a “gilbert cell” mixer. What is that? [Electronics for the Inquisitive Experimenter] explains them in a recent video. The gilbert cell is a multiplier, and multiplying two waveforms will work to mix them together.

• Hackaday ☛ A Paper Caper: The Hole Data

  Since the dawn of computers, we’ve tried different ways to store data. These days, you grab data over the network, but you probably remember using optical disks, floppies, or, more recently, flash drives to load something into your computer. Old computers had to use a variety of methods, such as magnetic tape. But many early computers used some technology that existed from the pre-computer era, like punched cards or, as [Anthony Francis-Jones] shows us, paper tape.

    On World Children's Day, Oliver Farry is pleased to welcome Cécile Aptel, Author and Deputy Director of UNICEF’s Global Office of Research and Forecasting. UNICEF is offering a sobering reminder: national and global policies too often leave the world's most vulnerable in the shadows. In a world of progress and innovation, 417 million children in low- and middle-income countries are still denied the most basic necessities: clean water, healthcare, education, nutrition. And even in a high-income country like France, official figures show that 2.76 million children live in poverty: one tenth of France's child population. Putting an end to child poverty requires political will and social commitment and to decide, collectively, that children’s well-being is non-negotiable.

The results of said investigation show how a mangled input file caused an exception to be thrown in the Rust-based FL2 proxy which went uncaught, throwing up an HTTP 5xx error and thus for the proxy to stop proxying customer traffic. Customers who were on the old FL proxy did not see this error.
