"""Gist to generate spreadsheet (Excel) pixel art from an arbitrary image.

Gist by Sadie Louise Bartholomew ('sadielbartholomew'), 05.08.21.

Q) Why would I want to do this?
A) Exactly. Programming gives us too much power to do silly and pointless
   things.

Requires certain libraries to work: see the `import` list.

We fit a exponential function for $f$: $f(V) = a \exp(V / s)$ and obtain $a \approx 0.02485702\ \mathrm{A}$ and $s \approx 0.229551831\ \mathrm{V}$. With this the deviation from the measured values from the total model $P(V) = 414\ \mathrm{mW} + V · 130 · f(V)$ is always below $8 \ \mathrm{mW}$, indeed it is atmost $\approx 3.19\ \mathrm{mW}$ and on average $\approx 1.28\ \mathrm{mW}$.

When not taking a fixed offset of $414\ \mathrm{mW}$, but instead also leave this as a variable of the fit, we obtain $\approx 412.3\ \mathrm{mW}$ for the offset, $a \approx 0.0249451511\ \mathrm{A}$ and $s \approx 0.229653915\ \mathrm{V}$ with a maximum error of $\approx 2.28\ \mathrm{mW}$ and a average error of $\approx{0.74}\ \mathrm{mW}$.

hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.
