One additinal trick is to compress your files before writing them to disk, using some kind of fast lightweight compression like parallel gzip (pigz command) or lzop. When parsing them, you will have smaller disk reads but higher CPU usage, which will give speed advantage if you have server-class CPU with lots of cache.
It’s these things. Notice how the thread is smaller than the shaft. You always need to drill a pilot hole, otherwise the thread won’t bite into the wood. The thread is also pretty tight, so screwing it two-three times in the same hole is enough to strip the wood in the hole, so it can be pulled out with tweezers with almost no resistance. It’s also slotted, so if you press too hard your screwdriver will slip out. And if you screw too tightly, the head will rip off, because it’s a mild steel.
Or you just hammer it in.
In Soviet Russia, all furniture was assembled by hammering wood screws. Then the assembled furniture was ripened for up to ten years in special humidity-controlled warehouses, allowing screws to expand and lock in place thanks to rusting. This required making screws from special-grade low-quality steel, and use extra-toxic glue for particle board planks so they would not rot. And still, only one in five assembled pieces of furniture did not have any rotten parts or fall into pieces when you attempted to take it home, making it even more luxurious. It is utterly impossible to repeat this level of craftsmanship in modern world.

Pinch my nose, spray my fingers with hand sanitizer, then walk away from their desk.
The pizza must be baked for 60–90 seconds in a 485 °C (905 °F) stone oven
My soldering iron only goes up to 450 ⁰C, and my Pb-free solder is melting at around 310 ⁰C.
90 seconds at 485 ⁰C will burn off the insulation on every cable in whatever I’m soldering. Gotta respect the pizza.
There is a whole lot of demand from industrial equipment manufacturers. When you attach a computer to your twenty thousand bucks robot arm or CNC drill, you need it small, reliable, readily-available, and brand-new, so you slightly overpay for Pi 5 for $200 and an SSD drive for another $200 to not rely on faulty SD cards, and if it breaks you can buy and replace it in 15 minutes, and future Raspberry Pi 6 will most probably boot from the same SSD and work with zero modifications, even contacts placement will be the same. Does it need 16 GB? Probably not.
Also, drone manifacturers. 16 GB RAM is just enough to run a computer vision AI model, and you won’t haul a used HP laptop on a drone.
My coworker has a separate monitor tilted vertically to have a permanently open terminal window.
Install Wallhaven plugin, then you can have two different wallpapers that are changed each ten minutes.
THE SKELETAL HAND!
And the veiny hand. Looks like there are several imaging modes.
But, but, eighty bucks! TI boards are seriously overpriced.
Yup, it would be super convenient to have one or two pins for ADC. Technically you have a DAC on Pi 4, if you repurpose the analog audio output, but on Pi 5 all you have is digital HDMI audio.
Oh well, an AD7705 voltmeter board costs only $2, and uses only six wires for SPI connection, including one of two precious precious 3V3 pins. And you’ll also need around three days to dig Github to find a working Python driver for it. But at least you don’t have to worry about burning your 3.3V Raspberry pins with 5V input voltage.
And at this point you are asking yourself - why not pay $3 for an ESP32 or a STM32? you can program it to use just three wires - power, ground, and UART TX, and you don’t need to read it 500 times per second like AD7705 and use 25% CPU of your Raspberry Pi Zero, you can program it to calculate an average RMS voltage once per second, and you can read a total of six ADC channels on ESP32, and on STM32 half of all the pins can be configured as ADC, and it’s also quite precise and low-noise, while on ESP32 ADC is more … consumer-grade.
Their original goal was to provide an affordable and customizable computing device with generic IO ports for a classroom, which they very much did.
14 years later, classrooms have a crapload of alternatives, ranging from $3 ESP32, which you can literally solder and throw away, to $500 Jetson, and all Raspberry Pi clones, like NanoPi or OrangePi, all with GPIO, UART, SPI and I2C ports, for all your microcontroller needs.
As for the embedded developers community (or ‘makers’ as kids call themselves nowadays) - these are the kind of people who dump two thousand bucks for a 3D printer and then use it twice a year. I think they will survive raising Raspberry Pi 5 price to $45.
And Raspberry Pi foundation pivoting towards business is a predictable move - those kids who used Raspberry Pi 14 years ago in a classroom are now business owners or technical leads in many businesses.
Y’all need a price chart. You are literally getting what you are paying for.
Raspberry Pi Zero is still very much available, and costs less than the original Pi 1/2/3/4. It’s enough for most microcontroller tasks, if you want cozy Linux with Python and don’t want to dive into RTOS and C microcode.
