How big is a kilobyte?

As best I can tell, there is no broad consensus on how large a kilobyte is. Some say that a kilobyte is 1000 bytes while others say it’s 1024 bytes. Others are ambiguous.

This also means that the industry does not agree on the size of megabytes, gigabytes, terabytes, and so on.

Not entirely new information to most of us, I would presume, but in my head canon a kilobyte is 1024 bytes,

@CraftComputing @Raspberry_Pi it's similarly shit like the #BananaPiZeroM2 / #BPi0M2 because if a CS professior can't get an SBC to output anything but 720p60, it's the fault of the company that creates it - not the users buying it.

SiFive’s P870 takes RISC-V further

ARM had a slow start on its way to move beyond microcontrollers and enter the high performance market. ARM Ltd made the Cortex A9, their first out-of-order core, in 2007. Throughout the 2010s, they gradually made bigger, higher power, and higher performance cores. Pushing performance boundaries isn’t easy, but today, ARM’s cores can be a viable alternative to Intel

Everything I know about floppy disks

Floppy disk drives are curious things. We know them as the slots that ingest those small almost-square plastic "floppy disks" and we only really see them now in Computer Museums. But there's a lot going on in that humble square of plastic and I wanted to write down what I've learned so far.

Exactly what it says on the tin.

A deep dive into Single Pair Ethernet

Having used a wide range of field device communications busses from simple 4-20mA, classic serial busses like UART and Modbus, and more modern CAN bus, native USB, and Ethernet options I'm always playing with different transports and protocols to see what solutions make sense in my grab-bag of designs for hardware projects.

I first became aware of Single Pa

While I totally agree (from my own work experience included) that encrypting firmware is essential, as well as having such guide... IMO I'd like to stress without diversifying encryption keys and making it unique per each device there's not much to gain from it https://interrupt.memfault.com/blog/firmware-encryption-with-python

It's been a while since I've worked with hardware... I have a Ryzen 5 3600 and it needs a discrete GPU as it does not do integrated graphics. So, without a dedicated graphics card the CPU wont boot at all right? I'm just looking for a POST message or beep.

I do need a GPU to complete POST right?

A visit to the one-man computer factory

The computer on Keegan McNamara’s desk is like nothing I’ve ever seen before. The machine sits on a light wood table, bathed in the sunlight coming into the second floor of McNamara’s Los Angeles house. McNamara, tall and blonde in jeans and a light khaki Carhartt jacket, walks over to the desk, sits down, and reaches over to hit the power button. Then he

I'm looming for a thiny #Thumb #Keyboard (kinda lie a 60% or 40% board that is tiny) that connects via #USB (wired!) to any host device.

Kinda like the #Dreamgear #MiniKey or the #Xbox360 #ChatPad but it needs to be either FLOSH or at least be still made to this day AND work natively as Keyboard.

It can't be wireless!!!

Wtf is this??

I photographed this in a thrift store in #Amsterdam a couple of years ago. It was lying on a little table near the used toys section. Absolutely NO idea what it was/is. The text scrawled in red ink (presumably to match the dials and logo on top) only made it more confusing to me. I'm not even sure what hashtags to use here...

DisplayPort: taming the altmode

The DisplayPort altmode is semi-proprietary, but it can absolutely be picked apart if we try. Last time, we found a cool appnote describing the DisplayPort altmode in detail, switched the FUSB302 into packet sniffing mode and got packet captures, learned about PD VDMs (vendor-defined messages), and successfully replayed the captured messages to switch a USB-C port into the
