A basic guide to security. [*updated*]

Computer security is something not so complicated, today i'll write down some tips for both computer and internet security.
First I'll start with the simple tips that some of you already know.

One basic method to protect your computer when you're not alone is by locking the screen, whatever OS you have, windows, linux, bsd your desktop environment or window manager will already have an option to lock the screen. You'll be surprised if you knew how many private data and passwords leaked because of that. Yes passwords too, all web browsers have the option to reveal saved passwords doh!

Set a strong password for your username, you can go as far as setting a BIOS password, of course you can reset it easily by removing the motherboard's battery in case you forget it

Poor performance in everything by your powerful GPU

I have noticed lately that a lot of people have their GPU drivers crashing, they also get very little performance out of their powerful graphics card, well sometimes it's the driver's fault but sometimes is not...
Then what is it? The answer is plain simple... "Miners" a lot of these people got their problem fixed (after ensuring it wasn't a GPU fan stopped working or abnormally high GPU temperature) by scanning with an antivirus (i always recommend malwarebytes, it's simple, powerful and does the job well). It turns out many people are getting their crapware out on the internet in hopes that someone will run it and start mining (with GPU cores) for them without the computer's owner notice it.

How to see how much VRAM your GPU uses under linux.

I pretty much said everything on the title, in this article I'm going to show you how to display your GPU VRAM and other information under linux using terminal.

First you need to type in:

lspci | grep -i VGA

Debian noRoot

Few days ago i decided to download a program from google store, it was Debian noroot from pelya, it says that it doesnt need a rooted device, that's good because i dont wanna void my warranty on the tablet, anyway i downloaded it, it's pretty large keep in mind so attempt to download/install it from a WiFi only.

Anyway after i set up my resolution to 1280x720 and font size to 0.7 it booted up. It's pretty nice and fast in my opinion after all it's a minimalist installation of debian jessie with XFCE , but don't think of it as a full OS in your tablet/mobile phone, more

Minor problems (Linux)

Problem1: error message when i tried to connect to the home network and see the shares, error message said "operation not valid or supported" something like that...
Solution: installed gvfs-backends and gvfs-fuse, logged out and then back in, everything's working as it should.

Problem2: for some reason enabling the MATE desktop environment's default compositor (to get fancy shadows under the windows) caused choppy resizing animation on *SOME* applications, yeap, some, e.g Eye of MATE while other applications like pluma or web browser were fine.
Solution: you need to... either install another compositor, e.g compton (i have my compton.conf and a small guide on some post here) or from Compiz panel, choose the resize effect to be something other than live-window-resize.
