Refurbishing my own Lightspeed Zulu headset

-
Image
[Update: I referred to the headset in this blog as a Zulu 3, but it turns out it was an original Zulu!  Anyway, thankfully the ear pads and cables are compatible across the Zulu -> Zulu 3 models.] I've been a fan of Lightspeed headsets ever since the Zulu line came out.  (Prior to the Zulus, they were terrible  headsets.)  I've used their "trade-up" program successfully, and I've also used it unsuccessfully (never got my rebate.  argh.)  Anyway, I digress. I have an old Lightspeed Zulu headset that is fine except that the rubber sheath on the headset cable is deteriorated and falling apart.  On a lark, I decided to do some searching for replacement parts and lo-and-behold, there are OEM compatible cable swaps on the Chinese retail site AliExpress!  I ordered a set of cables and new ear pads, and the replacement went smoothly.  I figured I'd document the process here for the less hardware-inclined. My worn-out Zulu 3 headset with the frayed...

K.C.'s 2022 summary of the Information Security field

-
A few years ago, a friend reached out with a question:  Her daughter was studying cyber-security and software development at a university, and she wanted to know my take on Information Security as a career field.   So I sat down and wrote up the following summary.   I think it's largely still accurate, and I've been asked for it again, so I figured I should just post it somewhere I can link to it. Disclaimer 1 :  This was written in 2022, prior to the AI uprising and the sudden massive contraction of the tech industry.   Disclaimer 2 :  I'm a Security Director / Architect / Engineer.  Below is my view on the industry landscape.  It is by no means complete  and is likely an artifact of my personal journey.  Others' views will be different.  Deal with it.  🕶️ -=-=-  Greetings! Infosec / cyber security is a VAST field.  It's awesome that you're interested in software development as well, though!...

Merida, Yucatan, Mexico

 We went to Yucatan for a week!  I've never been to the region before, so this was quite a treat.  Merida is the largest city on the Yucatan peninsula, and both the city itself and the state of Yucatan are rich in cultural and geological history. Just off the north coast of Yucatan is the site of the (buried) Chicxulub impact crater  - which is the impact that killed off the dinosaurs (and most of the other above-ground life on the planet) and changed the course of life on Earth completely.  The impact also created a massive underground hydrothermal system and hundreds of cenotes across the peninsula.  Yucatan is also rich in Myan history, and marked with the remains / ruins of the former Myan civilization.  An estimated 30% of the people in Yucatan still speak Myan, and the influence is quite prevalent in the names of places / features, the language, and the cuisine.  It was an amazing and educational trip.  We enjoyed exploring the city of...
