Gimp

Image editing? Drawing? Pixel art? If you wanna get into or just started at any of the above mentioned, you might wanna give GIMP a try! It's free, open source, and has a ton of functionalities! Personally I use it to do pretty much all my pixel art, either for games or this website, and also for any image editing, like stuff you see in pictures.
It takes a while to learn how to use everything, but there are tutorials and people willing to help online, so I think it'd be worth it to check it out!

Title attribute

One thing that you may often find the web is a tag with a "title" attribute, but what the hell is even that? Well when you put a title on a tag, it makes so hovering your mouse over it for a second or two (or tapping and holding an image if you're on mobile) a text is displayed, it could be the element's name, a replacement text in the case an image didn't load though the alt attribute already serves for that or just an explanation of what it is. And if you are in mobile, you can touch the image for a second and at the top it'll show its title too.
For example, this little guy under here, hover your mouse over him to find out his name!

"PLEASE HELP ME I DON'T BELNONG HERE!"

Drop files

Another thing you can encounter on the internet is places where you can drop files. Usually websites with these features are made for sending files elsewhere, such as attatching images to an email.
But I believe it can also be used for different kinds of things! With a little bit of JavaScript you can use them for other outcomes, using it as a simple drag and drop of elements can be a good tool.
Such as the example below:

index.html

One small thing that might help you navigate or just understand the web is understanding index pages. What are those? Well a website is usually made of different html files and each has a name, each different page is a file and they can also be inside folders. When looking at the URL of a page, you will often see something like this: [website domain]/[folder]/[file]
An easy way to recognize them is like this, folders always have a "/" in front of them after the website domain, and files do not.
"But Bruno!" you may ask to your screen for some reason. "If all pages are a file, and files don't have a slash in front of them, how come this page doesn't? it ends in a slash!"
Quite well observed, too... well observed... Well that would be because this page is an index page! You see, this is inside the "tools/" folder, but did you ever stop to wonder what happens if you go in a folder without saying which file? Well the first thing your browser does is look for a file named "index.html", if there is one, it goes there! If not, well then it goes to a broken page, you probably have seen a 404 or 403 page somewhere.
One thing I like to keep in mind is trying to avoid those whenever possible, so if you see a folder within my website there's a good chance it has an index page in there just in case!

Bookmark Scripts

(I'm not sure if this works outside of chrome, also computer only)

So you know how you can bookmark a website? That thing where you add a website as your favorite, usually displaying under the tabs (personally whenever I save one I like to edit the title to be empty and it's just a little list of different icons instead of cluttering with text that usually doesn't even fit on the space they have).
Well, one funny thing about them is that they're not only for website URLs, in fact you can throw javascript in them!

My brother taught me this the other day and it sounded so interesting to me, mainly because that's not what its purpose is, sounds more like a bug turned into feature that wouldn't even normally work but behold it is there.
So all you need to do is copy a text, like this:

javascript:([document.querySelector('video')].map(v=>{v.playbackRate=16;v.volume=0}))

add any page as a favorite or just edit an existing one, and replace the URL with the copied text! Then whenever you click the icon, it will run the script on the curent page!
That text you copied doesn't seem to do anything right now, but it's actually really useful. It's the one my brother gave me to show this working and it's a (albeit not the best working nor the siplest but indeed one I found fun) way to skip ads on videos. If you look at the script you can see that it looks for the current video player and does 2 things: Put the speed on 16x and sets the volume to 0. So whenever you're hit by an unskippable ad or a series of them you can just use that, in one or two seconds they're just gone!

Here's a random video that might include an ad, if not you can just test on the video itself.

This is for any general "life hack" that I find interesting enough to share.

Hard butter

You take the pot of butter out of the fridge but... Ah damn, yeah it is too hard now to try and spread with a knife on bread and such, maybe you can try heating the knife or the pot on the stove, hodling it upside down hoping the whole butter doesn't melt and fall on the stove... here's another solution I found tho:
Water, put water in the pot of butter, enough to cover the butter, leave it there for a couple of minutes, remove the water and bam! The butter isn't smooth but it's so much easier to spread, 0 risk, it's fast enough and works really well for something so simple.
