Life of #SRE as a Salesperson
https://tech.trivago.com/post/2024-12-20-life-of-sre-as-a-salesperson
Bueno, venga, va, nunca he hecho #presentación a pesar de que me he mudado más veces de las que puedo contar.
Soy #DevOps, #SRE o #PlatformEngineer, depende de cómo vaya el día. Mi trabajo no me define, pero me flipan los ordenadores desde lechón, así que un poco si.
Me gusta la broma y la chanza, pero si te ofendo con algún chiste, avísame para cambiarlo.
No me interesaba la política hasta que LOS PUTOS FASCISTAS me obligaron.
Para lo demás, la bio, o pregunta.

Week 7, HTTP and CDNs
After discussing the DNS, we now move on to #HTTP and HTTPS. While we don't have videos for these sections, hopefully the lecture slides can help you get an idea of what we're covering there. We review the basic HTTP protocol, peek at #QUIC and H3, and talk about load balancing and content delivery networks:
@RuthMalan @AlexPtakhin Thank you both! If only I could start every Monday like this. #SRE #Resilience #SystemsThinking

Week 7, The Domain Name System, Part III
In this video, we try to wrap up our discussion of the Domain Name System by addressing the nature of the root nameservers, looking at various different resource record types, observing reverse lookups, and thinking about how we can have assurance of authenticity and integrity of the #DNS results returned to us via #DNSSEC.
System Administration
Week 7, The Domain Name System, Part II
In this video, we dissect #DNS lookups performed on our EC2 instance, then discuss just how a caching resolver performs the lookup before we turn our instance into such a resolver.
System Administration
Week 7, The Domain Name System, Part I
In this video, we are beginning our discussion of the #DNS, the Domain Name System. We go back to the early days of the internet when copying /etc/hosts from system to system was the way to resolve hosts, and we cover the structure of the domain name space and the creation of the top-level domains.

Hey folks! If you are an experienced GO developer, there's a US remote job position open in one of the teams that work directly with me! This is a great opportunity to develop apps for our internal infrastructure that keep all the Blizzard games up and running. I've been having a great time at the company, and I can tell you for sure it comes with many perks. You work hard, and play hard!
Feel free to reach out to me in private if you would like a referral.

Week 6, Networking II: ICMP
In this video, we demonstrate the use of the Internet Control Message Protocol or ICMP (and its #IPV6 equivalent ICMP6) by tracing and analyzing ping(1) and traceroute(1) invocations.
System Administration
Week 6, Networking II: ARP and NDP
In this video, we illustrate the functionality of the Address Resolution Protocol (ARP) and it's #IPv6 equivalent, the Neighbor Discovery Protocol (NDP).

Week 6, Networking II: A simple request II
In this video, we pick up our tcpdump output collected in the previous video and begin to analyze the packets we find in there. We observe our AWS instance being scanned by some random host on the internet, see the ARP requests and replies, our DNS query, and the TCP packets for our HTTP request, yielding an illustration how a simple request causes traffic across multiple layers.
System Administration
Week 6, Networking II: A simple request
In this video, we trace a simple HTTP request made via telnet to find out just how exactly our application knows how to connect to the remote server. In the process we learn about the ktrace(1) utility (strace(1) on #Linux), as well as the nsswitch.conf(5), hosts(5), and resolve.conf(5) configuration files.
System Administration
Week 5, Networking I: A Network of Networks
In this video, we look at how independent networks connect to one another, how Autonomous Systems numbers allow us to identify network operators, and how peering between independent ASs works.
System Administration
Week 5, Networking I: The Physical Internet
In this video, we look at the physical structure of the internet, with a focus on submarine internet communications cables. Jumping from the bottom of the OSI stack all the way to Layer 9 ("political"), we then discuss how different countries use their political power to enforce internet blocks on their citizens, leading us to warrantless wiretapping in AT&T's room 641A.
System Administration
Week 5, Networking I: IP Allocation & IPv4 Exhaustion
Mommy, where do IP addresses come from? We discuss how IANA allocates IP addresses to the Regional Internet Registries and try to illustrate just how large the #IPv6 address space is.
System Administration
Week 5, Networking I: #IPv6 Basics
In this video, we get familiar with our Big Hero IPv6, looking at the structure of the IPv6 header and IPv6 address representations.
System Administration
Week 5, Networking I: IPv4 Basics & CIDR subnetting
In this video, we cover the basics of the 32-bit IPv4 address and how we organize networks using Classless Inter-Domain Routing or CIDR subnetting. (Don't worry, #IPv6 comes in our next video.)
It's been a few months since I was laid off, and job hunting is A Lot. So here's the #GetFediHired pitch:
I'm still defiantly calling myself a software generalist; background includes #SRE/#DevOps, #DistributedSystems programming, and #SDET/QA. I like working behind the scenes, especially wrangling tech debt and improving processes and tools and docs. I'm a #Python wizard but comfortable with various tools and paradigms.
Based in #PDX, won't move within the US, strong preference for remote.
