Simple TLS Gateway

Posted . ~2min read.

Well, 2020 is certainly a strange year… Some of us have been working from home for a very long time while others are now just understanding the benefits.

Paso a Paso

Posted . ~2min read.

Hoping that everyone is staying safe and seeing the impact to many of my friends has been nothing short of devastating. Our favorite local restaurants have resorted to take-out and if they’re lucky are getting 25% of the business they’d normally receive. (Quick shout out to Blue Water Bay here in North Florida and if you’re anywhere near Maggie Valley, NC, check out Frankie’s)

The bakery has seen all events for the rest of the year cancelled… which includes weddings, graduations, caterings, and well… everything. We’ve been very grateful for all the orders to the bakery’s online store (and Yeni literally yells “woo hoo” when an order comes in).

ITEXPO 2020

Posted . ~1min read.

Had a great time visiting with members of the open source VoIP community in Fort Lauderdale for open source world / itexpo 2020.

I was excited to discuss Kamailio and other aspects of communication as well as get some important hardware discussions in person… it’s an interesting time as hardware and software vendors seem to be merging left and right.

Goodbye Citibank

Posted . ~4min read.

In 1990, while a freshman at UF (Go Gators!), I applied for and received my first credit card. The card, from Citibank, was a “college special” with a whopping credit limit of $600.00 and fees/penalties as high as the Federal Government would allow.

This said, there was no yearly fee and I knew at the ripe age of 18 that if I paid my balance on time, my cost was 0.00. Granted, I didn’t have much money (like generally a bank account of 200.00 or so) and got the card in case I needed food and didn’t have the cash.

Coming Soon: ITEXPO

Posted . ~1min read.

From February 11th through 15th, 2020, Open Source World (or open source summit?) will be colocated at ITEXPO 2020 in beautiful Fort Lauderdale, Florida. This year, I will be speaking the gospel of Kamailio with a presentation entitled, “Using Kamailio to Secure Your Communications” (currently scheduled for February 13th at 3pm).

Go vs Node

Posted . ~2min read.

I’m not a programmer. Never tried to pass myself off as one — which made for a really, really awkward interview once… but that’s another story.

Anyway, I’ve been creating “APIs” in Perl for a while using Perl CGI on NGINX. It’s not a REST API whatsoever, but I enjoy scripting in Perl and (1) got the job done, (2) was fast, and (3) no learning curve.

Astricon 2019 Thoughts

Posted . ~4min read.

TL;DR A few weeks ago, I had some strong concerns over Sangoma’s stewardship of Asterisk and FreePBX. Since that post, Astricon showed that Sangoma definitely appreciates the open source VoIP community and I’m optimistic for the future.

I, along with 300+ others, attended Astricon 2019 during the last week of October in Atlanta, Georgia. This year’s Astricon differed dramatically from others — there was no expo hall, fewer presentations, fewer tracks.
