What an unprocessed photo looks like
The image isn't even black-and-white , it's gray-and-gray: While the sensor's ADC can theoretically output values from 0 to 16382, the data doesn't cover that whole range.

5x5 Pixel font for tiny screens
All characters fit within a 5 pixel square, and are safe to draw on a 6x6 grid. The design is based off of lcamtuf's 5x6 font-inline.h, which is itself inspired by the ZX Spectrum's 8x8 font.

Regressive JPEGs
One of the cool features of JPEG files is that there's the option to save low frequency components first. This means that a partially downloaded image will be displayed at low resolution instead of being cut off.

You already have a Git server
If you have a git repository on a server with ssh access, you can just clone it:

No adblocker detected
Internet ads are horrible: They waste your time, and the industry behind them is actively making the internet a worse place. Payouts are so small that the only way to survive is to turn your site into an ad-filled hellhole with no real substance. (see: Modern social media )

You can make up HTML tags
Browsers handle unrecognized tags as a custom element, with no effect beyond what's specified in the CSS. This isn't just a weird quirk, it is standardized behavior If you include hyphens in the name, you can guarantee your tag won't appear in any future versions of HTML.

Hosting a website on an 8-bit microcontroller
My victim is the AVR64DD32 which is quite similar to the Atmega328 of Arduino fame. Compared to the older Atmega, these AVR DD lines are cheaper for the same memory, use a single programming pin and have nicer peripherals:

Why you can't color calibrate deep space photos
Color is the most disputed part of astrophotography: Every image looks different and the internet is full of arguments over what colors are correct or natural.

Transfer files over an Ethernet patch cable
It's possible to just connect two computers together with Ethernet and do a bit of IP configuration:

Increasing the lifespan of a bulb makes it worse in every other way
This isn't quite right , but it's the type of wrong that cites its sources and hides in the part you'd never think to fact check:

Why does C have the best file API
Ok, the title is a tongue-in-cheek, but there's very little thought put into files in most languages. It always feels a bit out of place... except in C. In fact, what you get is usually a worse version of C.

Making glass-to-metal seals for homemade vacuum tubes
When making vacuum tubes, the glass is actually the easy part: premade tube stock of almost any size is easily available.
