And if you encounter a true paywall, use Archive.Today to bypass it. Just paste the paywalled url into the blue “search archived snapshots” box near the bottom:

for example, instagram has disabled right click save. here I am trying to save a picture of this girl with a pumpkin sweater, but I am thwarted by the lack of right click save!

to get around it, right click and go to “inspect” or “inspect element” (it’s called different things depending on what computer you’re using)

shimmy around the webpage code until you find the “src” bit. It will helpfully tell you when you’ve found it because the image, and only the image, will light up as if you selected it.

that source is the link to where the image is hosted on the website. click the link.

find the actual hosted image. right click on that.

There’s a school of thought that says that to fully understand something, you need to build it yourself. OK, we’re not sure it’s really a school of thought, but that describes a heck of a lot of projects around these parts.

[Tim] aka [mitxela] wrote kiloboot partly because he wanted an Ethernet-capable Trivial File Transfer Protocol (TFTP) bootloader for an ATMega-powered project, and partly because he wanted to understand the Internet. See, if you’re writing a bootloader, you’ve got a limited amount of space and no device drivers or libraries of any kind to fall back on, so you’re going to learn your topic of choice the hard way.

[Tim]’s writeup of the odyssey of cramming so much into 1,000 bytes of code is fantastic. While explaining the Internet takes significantly more space than the Ethernet-capable bootloader itself, we’d wager that you’ll enjoy the compressed overview of UDP, IP, TFTP, and AVR bootloader wizardry as much as we did. And yes, at the end of the day, you’ve also got an Internet-flashable Arduino, which is just what the doctor ordered if you’re building a simple wired IoT device and you get tired of running down to the basement to upload new firmware.

Oh, and in case you hadn’t noticed, cramming an Ethernet bootloader into 1 kB is amazing. If doing big things in small codespaces floats your boat, check out the winners from our own 1kB challenge.

Speaking of bootloaders, if you’re building an I2C slave device out of an ATtiny85¸ you’ll want to check out this bootloader that runs on the tiny chip.
