This is not just a "happy birthday" post for Linux, but also a reminder that despite it becoming big and professional, the freedom to tinker with Linux remains accessible.

I had to use this freedom recently when I discovered that V4L video pipelines could buffer up to 32 frames both on the encoder and decoder (unacceptable, we demand minimum latency!) so it was again time to recompile the kernel. :)

My previous time to recompile parts of Linux had been a week ago. Some hacker had discovered a way of tricking their WiFi card beyond the legally permitted power - with what I understand as thermal compensation settings. Wanting to taste the sweet extra milliwatts, I noticed that nobody was packaging that driver as a binary, so the only way to get it was to patch and recompile its kernel module.

Finally of course, thanks to Linux we have countless open-source drivers and if you want to venture onto the path that Linus Torvalds took - of building an operating system - congratulations, you have less obstacles in your way. :) Some people have taken this path with the Circle project and you can compile your homebrew and bare-metal kernel for a Raspberry Pi with reasonable effort, and it can even draw on the screen, write to serial ports and flip GPIO lines without reverse-engineering anyone's trade secrets. :)

it's weird, but legal for some reason. Giving back energy to the grid can cost money. Shy of just stacking a bunch of batteries, what could I do with the spare summer sunlight?

An Indian entrepreneur is using sugar, cellulose, and corn fibers to make a plastic-like carrier bag for small Indian businesses.

His company Bio Reform has already replaced 6 million plastic bags in the checkout counters of stores all over India.

Based in Hyderabad, Mohammed Azhar Mohiuddin first got the idea during the general mayhem that arose during the pandemic. Mohiuddin was looking at global environmental issues with the hope of finding one his entrepreneurial spirit had the capacity to tackle.

Hi. Hopefully someone can help me out. I have installed Combustible as an Android Lemmy client but when I try to connect to https://slrpnk.net I get an error: "unable to connect to specified Lemmy instance!" I'm willing to try a different app but would prefer FOSS.

So I enjoyed this. This is the kinda stuff that no one ever needs until they need, but it was insightful and so I thought worth a share.

Summary:

This video is the first part of a series about how to engineer the perfect pool. In this video, the speaker talks about the importance of variable speed pumps for energy efficiency. They discuss how to choose the right pump for your needs and how to install it. They also provide tips on how to save energy and money with your pool. Here are some key points from the video:

• Variable speed pumps can save you a lot of money on your energy bill.
• You can choose from a variety of different pumps to find the one that best suits your needs.
• It is important to consider the size of your pool and the flow rate of the pump when making your decision.
• You can also use a pool robot to help keep your pool clean.
• There are a number of other things you can do to save energy and money with your pool, such as using a solar cover and investing in a heat pump.

Overall, this video provides a lot of valuable information about how to engineer the perfect pool. If you are looking to save money on your energy bill or improve the efficiency of your pool, this video is definitely worth watching.

Herbicides have a long history of negative consequences. Glyphosate and paraquat, among other pollutants, are extremely harmful to human health and the environment. These pollutants impair soil quality and destroy beneficial organisms such as pollinators. Furthermore, the widespread use of herbicides has resulted in weed resistance, making chemical management less effective.

Kenny Lee, co-founder and CEO of Aigen Robotics, is personally committed to reducing pesticide use. Lee, a glyphosate-related non-Hodgkin lymphoma survivor, has collected $19 million for his startup to produce solar-powered weeding robots. “We’re on a personal mission,” Lee says, emphasizing their dedication to sustainable agriculture.

"To help feed the country’s population, an inventor, Toufic Hamdan, created a commercial bakery to bake bread in solar ovens. The startup “Partners With Sun” has installed a solar convection oven on the bakery’s roof. The Solar Oven uses large silver mirrors to capture and magnify the sun’s rays to build heat. The heat is transported by a transfer fluid which is then used to help operate a convection oven, allowing it to reach a baking temperature of between 300 and 400 Celsius. The heat is used directly in food and beverage production. " Baking Bread in a Solar Oven | Happy Eco News

According to the company website, “The Solar Oven cuts up to 80% of the bakery’s fuel bill.”
