reddit.com/r/CompTIA/comm… Fella used my course and got an 831 on the Network+ But more importantly? They used Packet Tracer (which is free) to learn how to configure and implement networks I cannot emphasize this enough: Passing these exams is useless if you can't do the stuff

You prioritize the job over school The ONLY job that will care about your GPA post-grad is the first one.... But if you've been working there throughout school, then they won't care either What's worth more: your GPA or a paycheck after you graduate?

Moving to Exchange Online was the perhaps the happiest day of my life...or was it the birth of my children? Eh, we'll call it a draw

Repeat after me: nobody cares about you more than you do If you don't take your training into your own hands, you are seriously gambling with your career and even current job prospects

I'd call that a perk myself Lots of downtime in IT when the ship is well-oiled. Leaves you time to either level up, apply for new jobs, or work on a side business

🚨 UPDATE: 19 MILLION exposed NGINX instances hit by the 18-year-old NGINX RCE found by AI. Top exposure by country: - United States: 5,340,011 - China: 2,540,008 - Germany: 1,871,780 Note on ASLR as added security: not all of these instances will have ASLR disabled, but every one of them is running a version inside the vulnerable band. The vulnerability is a heap buffer overflow. ASLR randomizes memory layout, which makes reliable RCE much harder because the attacker cannot predict where their payload or useful gadgets land. But the overflow itself still happens. The corrupted memory still causes the NGINX worker process to crash. ASLR-enabled hosts are still trivially DoS-able. ASLR-disabled or non-PIE builds are RCE-able. Either way, patch ASAP!

Dumb question in the IT space As you get more advanced in your IT career, "hardware" becomes the realm of electrical engineers If you're getting into IT, the only answer for advancing your career is pivot to programming or learn automation Hardware is a separate field entirely

Certifications are only worth what people think they're worth You could think it's the best exam format in the world and evaluates your knowledge like nobody else Doesn't matter If the industry doesn't think it's worth anything, then it's not worth your time testing either

Inherited an environment with a bunch of engineers who used Linux desktops One of them used a single space character as their password That has since been changed
spencer@techspence

Ridiculous experiences with passwords… - cracked 4 20+ char pass phrases because they were popular Bible verses and song lyrics - guessed an admin password after cracking a service account hash that was named similarly to the admin account - cracked a RID 500 account that was configured as a service account, password was 7 characters - sprayed a password a client gave me on a purple team (for the telemetry) and found it was used on hundred of enabled accounts Let’s hear yours 😅

Cloud engineering is often a lot of DevOps and Automation Want to become a Cloud Engineer? 1. Pick a cloud: AWS, Azure, and/or GCP 2. Pick an automation tool: Ansible or Terraform/Tofu is common 3. Learn container-related tech stacks: Docker and Kubernetes 4. Probably learn some CI/CD tools

Having difficult conversations is like studying for an exam or going to the gym Most of the time the answer is just do it - sure there's a totally wrong way to do it, but there's also no golden bullet combination of words You just gotta pull the trigger
