Dell XPS laptops are great for mobility and they are really silent even with load. Got one for work and this laptop is an absolute beast when it comes to battery savings during the day and hardware support. Ubuntu 24.04 recognized all the hardware including the fingerprint reader built-in into the power button.
But one thing was not that great: battery consumption after closing the laptop lid.
Este é um pequeno grande relato de como trouxe meu cão, o Beico(isso, misspelled Bacon ou Bacon abrasileirado) para a Irlanda.
De antemão aviso que este não é um processo fácil e neste artigo tentarei fazer um passo a passo do processo de “importação” do nosso doguinho relatando minha própria experiência.
Este guia se restringe ao transporte de cães na cabine visto que foi o processo que fiz já que cães braquicefálicos não são permitidos no compartimento de cargas. Também não entrarei em detalhes relacionados a transporte de pets por terceiros pois eu mesmo trouxe o cachorro e o processo de vir com outro tutor possui umas diferenças, apesar de a grosso modo o procedimento do Certificado Veterinário Internacional ser feito através do mesmo recurso online.
Este relato será ora em primeira pessoa e ora em terceira, quando eu achar que as informações devem ser direcionadas em forma de instrução para aqueles que lêem este blog.
It’s been a long time since I use OpenWRT on my home routers, and prefer to buy a router that could be a little outdated but has support to this wonderful firmware.
This is a quick tutorial on how to automate qr code generation and password rotation for your OpenWRT-based devices.
As you may notice, this is almost a part 2 of my Secure your boot process: UEFI + Secureboot + EFISTUB + Luks2 + lvm + ArchLinux. Except that here i’ll not talk about all the secureboot stuff that i’ve already ran into on my last blogpost. This one is specifically focused on how to achieve the same setup using Fedora.
This blogpost compiles my personal opinions around using bootloaders on EFI environments so, the classic “opinions expressed here are solely my own and do not express the views or opinions of my employer” applies.
PRIME is a technology used to manage hybrid graphics. It was meant to be a resource saver since you can configure it to use only the Integrated GPU, and render offload to the dedicated GPU whenever is needed. But that is not what happened in my real life situation.
This tutorial isn’t a basic setup how-to in a way you will learn how to install Arch Linux, neither is intended to replace the Installation Guide, This is a guide for those who want a laptop with data-at-rest encryption and a verified boot process using SecureBoot.
I’ll not be arrogant saying that this setup is “tampering-proof” since this also depends on your firmware manufacturer, but I believe that this is a notebook setup with good enough security.
There comes a time in life where you enable a high-level protection in your firewall, but you somehow forget the basics and that is where the problem lives..
These are some of the commands I use most, or, zimbra commands that were relevant to a very specific goal and i had to document them to avoid losing them :)
