"Smartifying" my Hi-Fi system

Have you ever wondered if it would be possible to make a "dumb" "hi-fi system" smart? Not that smart, but simply connect a device and it would play whatever stream you want into you? Maybe even stream from your phone? Then this is for you.

The Asustor firmware can automatically control the fan speed, but sometimes the NAS can get pretty warm. Can we do better?

It's a x86-64 machine, so it should be possible... right?

Improving my NAS monitoring

Improving my NAS monitoring

I've decided to improve my NAS monitoring scripts a bit. You know, stuff you usually do on a Saturday.

I've played and tricked my NAS before, but now I want to know how it reads its sensors. Let's go deeper!

This is a story of why you should always check permissions on the backend!

Cabify and why you should not send sensitive data over public APIs

Cabify and why you should not send sensitive data over public APIs

Sensitive data leakage is a serious issue. Even though some people don't really care much, in the wrong hands such data could be used for pretty much anything, including identity theft. Let's take a look at this issue today with one of my favorite transportation apps: Cabify.

Changing jobs and the shitty parts about doing that

This is a story of how I decided to change (or not - we'll see that soon enough) jobs, life perspective changes and tricky decisions. Enjoy.

Bank app permissions

Exactly one month ago I said I was going to write a post about my bank's app permissions and the issues with privacy on it.

Dealing with App support

Every software has bugs. It's impossible to run away from them, and, if you're not the developer, you might have to report it to get it fixed. And that's what I usually do if the bug is way too annoying. However, sometimes things don't really go... well, *smooth*.

Production bursts

I'm a weird guy coding. I'm usually more or less quiet, usually listening to normal/calm music. I'm productive like that, and it works well.

Windows 10 vs. broken laptop GPU

I'm pretty sure I once commented that I have a broken laptop. It's my sister's old machine, which isn't that bad (better than mine), but she managed to *kill the GPU by overheating* the whole thing.

ESP8266: part I

Ah, microcontrollers. Man, I missed playing with those. Seriously. Who here who has ever played with one doesn't miss countless hours of programming and weird debugging? It's always *so much fun*... mostly.
