This photograph was composed less than 15 minutes ago to portray the heat sink which has now been installed on the Broadcom Wi-Fi integrated circuit

In a passive set up the heat sink does not do much, the temperature drops just with a couple of degrees and the order of two to 3° C

With a fan spinning air on the heat sink the temperature drop is significant

From my experience with electronics I know that heat sinks designed for Passive cooling have longer fins. For example the heat sink that I used to repair my National monochromatic television 12" when I was a kid, had very long fins and the heat sink was about as tall as my thumb {8.5cm}

That analog Integrated Circuit controlled almost everything in the television, which made the circuit board quite Compact and easily maintainable

The photograph composed in 85F Warming Light, shows a Raspberry Pi5 board inside a red plastic case. The board is green with various components and labels visible. The central component is a large black chip with a white heatsink above it. There are four USB ports, two micro HDMI ports, and a microSD card slot. The board also features a GPIO header on the right side and a power connector on the left. The Raspberry Pi logo is visible in the center. The board is mounted in a red plastic case with visible screw holes and a spinning fan attached to the right side. Ovis2-8B 🌱 Energy used: 0.141 Wh

One program that was written very well, with both the beginning and the master user in mind is this one

Raspberry Pie imager. If you barely know how to move in a graphic user interface you will still be able to make the image.

If you're a seasoned POSIX operator like me, the imager will still do exactly what you want and give you the proper results

The photograph composed in total darkness, shows a computer monitor displaying a desktop environment with a blue-themed wallpaper featuring a silhouette of a samurai holding a sword against a mountainous background. The screen is tilted at an angle, with the top right corner showing a red window with the text "Raspberry Pi" and a logo, indicating the operating system. Below this window, there is a terminal window with white text on a black background, displaying lines of code or commands. The bottom left corner of the screen shows a black terminal window with white text, possibly displaying system information or logs. The monitor is in a dark room, with only the screen providing illumination. The bottom right corner of the screen shows the time as "10:01" and some system icons.

@stefano it works fine here on the Raspberry Pi 5
Maybe the difference is that this system runs on 64 bits {OS/ DDR4 memory}

The image shows the back of a Raspberry Pi 5 box. The box is primarily beige with black text and graphics. The top right corner features the Raspberry Pi logo and the text "Raspberry Pi 5" in bold. Below this, the features of the Raspberry Pi 5 are listed, including: 64-bit quad-core Cortex-A76 processor 8GB LPDDR4X SDRAM 2x USB 3.0 ports 2x USB 2.0 ports 2x micro HDMI ports (supports up to 4Kp60) 802.11b/g/n/ac wireless Bluetooth 5.0 2x Gigabit Ethernet port (sold separately) 2x 4-lane connectors for camera or display peripherals PoE-capable (requires PoE HAT, sold separately) PCIe expansion connector (requires PCIe power adapter, sold separately) 5V/5A USB-C power supply (recommended for best performance, sold separately) The bottom left corner contains a barcode with the numbers "5 056561 803326" and the Raspberry Pi logo. The bottom right corner includes the HDMI logo and a statement about compliance with the HDMI specification. The text "Get started" and the website "raspberrypi.com/products/raspberry-pi-5" are also visible. Ovis2-8B 🌱 Energy used: 0.326 Wh

With firefox running using 4 open tabs, Debian ARM uses just 2.08GB (1GB=1024MB) of RAM. It looks like I should just browse in ARM linux on the SBC

A new stepping of the RP2350 ARM/RISC-V microcontroller fixes a number of bugs and officially supports 5V-tolerant GPIOs (however, the chip must remain powered while 5V IOs are used).

I wrote a simple gpioctl wrapper with Python in NetBSD RPi configurations. This wrapper cannot change the pin mode. Please configure manually in /etc/gpio.conf

Well, my reality is fortunately the one where one looks around and observes what is actually happening.

In this the observable reality, the jobs want .NET and C♯ because that's what's in use, and no-one wants Java anywhere near like they used to because the promised world where Java was everywhere, from applets in our WWW browsers to applications on our desktops running out of the box on all sorts of processors, with none of this emulating ARM on AMD infrastructure needed, simply has not materialized.

Indeed, sometimes the Java postings are bait-and-switch for C♯; because the pimps just generalize OOP.

The language with so much promise all of those years ago, went to die at #Oracle.

I've been talking about it for months, but I finally followed Jami Kettunen's instructions and got Chimera Linux installed in my Yoga Slim 7x ARM laptop.

Windows was crashing every few days (while unattended) with the error "The system has rebooted without cleanly shutting down first. This error is caused because the system stopped responding and the hardware watchdog triggered a system reset." even after a full restore.

I'm hoping Linux is more stable.

I learned today that Shadow Stack (SHSTK) and Indirect Brach Target (IBT) are modern x86 / ARM CPU features to counter binary exploits.
