It's An Ubuntu Server!: Username Resolution with DNSmasq

I don’t actually have a domain name to use but let’s pretend!





My server’s name is called Saturnine-U

We could set up a host file on every machine on the network:

192.168.0.2  Saturnine-U (though I wonder how that - will fit in)

but that’s not efficient! Let’s use DNS, it’s like a central directory.

I can configure this on a Cisco router easily but Ubuntu? Well, that’s why we’re here! Learning!

Let’s install dnsmasq

(I type in sudu apt get dnsmasq because ‘get’ is how we…got stuff in Red Hat but nope, get should be install)



Nice, then I save and escape (before going back in to check that I saved properly)
and restart with sudo systemctl restart networking.
[I forgot ‘networking’ at first and got ‘too few arguments’ as a message. Helpful!]




Back to opening ports with sudo ufw allow 53/tcp
It also allows it for IPv6.

(I’m doing this in a starbucks so I can’t wander in and mess with their router. Well, I could, if I knew the IP address. Any guesses? Just kidding…)

I’d have to restart it. Ideally, I could ping Saturnine-U with just the name and it would work.

I’ll see if I can get it to work at home with my Comcast router and update if I can!

Azure Networking Options - Core Cloud Services

I have done a lot of AWS things on here. Time to give Azure some attention. After all, since employers don't think Cisco or COMPTIA certifications are important, maybe Microsoft ones are?

First, let's really think about why these are the two biggest cloud services providers in the world:

They've been doing internet things for a long time.Amazon launched in 1995, a virtual bookstore.
Microsoft, well, you know. 

They've lived, breathed, and frankly, created, infrastructure that we use today, that they're selling to us today. Of course the Store of Everything and the Company of Everything would encourage us to put everything in their hands.

Also: Azure has a lot less silly names for modules. Important. I appreciate straightforwardness.


I said 'a lot less', not '100% sensible names'

Microsoft has a clear set of Azure Fundamentals that anyone can interact with. Let's talk about networking basics, basically to say, again, "Hi, employers, I have an …

Grace Hopper Celebration 2019 (GHC19)

From Aicha Evans' speech at the Keynote.
September 6th - I receive an email from Anita B Organization, saying "We read your application, we like your website, and here's a free ticket to GHC 2019 in Orlando, Florida!"


After a few more questions, it seemed everything was on the up and up, and so I accepted - and that's what this post is about!

For those who don't know, Grace Hopper Celebration is the largest gathering of Women in Technology in the world.

On a personal note, This is the first trip I've taken without my parents. Sure, they've left me behind to go on vacations, but I've never left them. I was totally worried! But you know what happened?

I met a lot of cool people in Orlando, learned a lot of neat things, and had a blast just walking around airports for upwards of 8 hours.

New Delta Sky Club on Wikimedia I really, really love airports! And I survived.

I know in the past, I've wormed my way out of jobs despite being interested simpl…
