End boss @bert_hu_bert continued his series of business related presentations for network geeks. Knowing your tech and conveying such a clear message on business stuff as well is off the chart. Thanks bert

2021 Hyundai Ioniq SEL car infotainment software appears to be encrypted with NIST-example RSA keypair and a ZIP-password in plaintext, in a script. Never roll your own crypto, but also don't forget to substitute your keys, lol. 😂 programmingwithstyle.com/pos…

T-Mobile is experimenting with 2G carriers inside the 900MHz 4G band. They disabled some 4G subcarriers so they don't overlap. There is now a 5MHz gap free to enable 3G900 again. It would be logical that the entire 2100MHz band is moved to 4G afterwards.

I'm honored to be presenting at DjangoCon this year! We'll take a deep dive into how we built object-based permissions in #NetBox, and how you can replicate the approach in your own project.
#DjangoCon US 2021 tickets are now available, including free and donation tickets. Sponsorship opportunities, including a job board, are available now. The event is on October 22nd and 23rd. 2021.djangocon.us/ #Django

Nice kit!
This is what it looks like when my glorious Network Engineering backpack pukes. The things I need access to most often are normally stored in the outside pockets.

Suppose I authored a dedicated ~3 hour MPLS course at @pluralsight … what should it contain? Keep in mind I have existing courses that cover the basics of it already, like LDP, VPNv4, and QoS. Would appreciate a retweet for visibility and greater feedback!
