Episódio 102: Marcelo Mello - Red Hat E Home Assistant

Nosso convidado de hoje é um veterano do mundo do software livre e do Projeto Fedora, tem um título bem bacana, Principal Technical Support Engineer, na Red Hat, possui um monte de certificações de dar inveja a qualquer um (RHCSA, RHCE, RHCA, RHCSS, RHCDS, RHCVA, RHCI) e hoje mora na Carolina do Norte. É com grande prazer que nós recebemos nosso convidado de hoje, Marcelo Mello.
Este é mais um episódio que foi gravado ao vivo pelo canal do YouTube. Começamos perguntando para o o Marcelo como ele iniciou no mundo Open Source e como foi parar na Red Hat. Em seguida ele nos conta como e o seu trabalho como Principal Technical Support Engineer.
O Marcelo se mudou há alguns anos para a Carolina do Norte nos Estados Unidos. Por isso perguntamos como foi a experiência, se ele e sua família estão se adaptando a cultura, também, o que sente falta e o que gosta comparado com o Brasil.

What we learned shifting Red Hat’s premier event

“Learn to pivot” has been the mantra for 2020. Like most businesses, March 2020 was a challenging time for us on the Red Hat marketing team. With COVID-19 spreading across the world, and businesses sending their employees to work from home, it became clear that Red Hat Summit, scheduled to be hosted in April in San Francisco, could not go on as planned.

By mid-March we were in full pivot mode to change Red Hat Summit, the premier open source technology conference, from an in-person event to a full digital experience. The challenge – that the event would still immerse our attendees in everything that makes a Red Hat event special. It was certainly an exciting ride, and on April 27, we opened the Summit virtual experience to the world. In the end, we had more than 50,000 attendees from more than 100 countries visit the live environment. We learned a lot of lessons along the way - below are a few successes we had while pulling off this event, and a one tip for improving a virtual experience.

Success #1: Be authentic to your brand

Red Hat has a unique, open culture that is at the heart of everything we do as an organization, and we try to make sure that culture is well-represented in our events. While shifting to a virtual event environment, we knew we needed to keep that Red Hat community feel, even though we wouldn’t be in person. That meant following some of the same guidelines we’d use for an in-person event, including:

  • Give attendees access to Red Hatters: At a live event, you’d do this in booths and one on one meetings. In our virtual events, we did this through chat rooms and “ask the experts” live sessions.

  • Make customers the star of the show: Red Hat products enable our customer to do some amazing things, and just like at a live Summit, we showcased their successes through customer keynotes, breakout sessions and our Red Hat Innovation Awards program.

  • Keep things fun: There’s always a lot to do at Summit, beyond attending keynotes and breakout sessions. We added open source games, challenges for completing tasks in the environment and opportunities to win prizes to the virtual experience to bring some of the excitement of Summit into attendees’ homes.

  • We were surprised at how well the gamification of the environment worked for helping with engagement numbers. Over 26,000 attendees earned at least one badge for watching keynotes, exploring the environment, and interacting with content from programs like Red Hat Innovation Awards.

Syncing GitHub Forks

So you’ve heard that this GitHub thing is pretty sweet for collaboration.

You found a sweet project someone started on GitHub and followed some tutorials on forking this, cloning that, etc. You do some extra work and make some commits on your version. All is looking great.

Then you see while you’ve been fiddling with your version of the project the original author put in a real cool feature. You want to include it on your version but you’re not really sure how. You could try just start copying and pasting the code. Or heck, just ditch your own work and work off that new version.

But you know you’re better than that! You’re one bad-ass learning whatever you need. And you figure others have had the same exact issue themselves when working on a new project. So there has to be a better way.

There is a better way! Enter GitHub forks! However, there is a caveat. Almost all solutions bring in the baggage of extra complexity. We specifically need to discuss syncing your fork. If you’re not sure what a fork is exactly, the next section will give you a brief overview. If you’re familiar enough with the forking concepts, you can skip the next section.

Set Up SPF and DKIM with Postfix on CentOS 8/RHEL 8 Mail Server

SPF and DKIM are two types of TXT records in DNS that can help with preventing email spoofing and making legitimate emails delivered into the recipient’s inbox instead of spam folder. If your domain is abused by email spoofing, then your emails are likely to landed in recipient’s spam folder if the recipient didn’t add you in address book.

SPF (Sender Policy Framework) record specifies which hosts or IP addresses are allowed to send emails on behalf of a domain. You should allow only your own email server or your ISP’s server to send emails for your domain.

DKIM (DomainKeys Identified Mail) uses a private key to add a signature to emails sent from your domain. Receiving SMTP servers verify the signature by using the corresponding public key, which is published in your domain’s DNS records.
