People are getting their CCNAs left and right. I did my CCNA in 2010 and passed the exam hardly by 1 mark🫣 But CCNA opened up doors for me that I couldn't have imagined. Yes just a CCNA, not CCNP or CCIE.. CCNA alone is very powerful when combined with hands- on experience.

New network engineer got hired right after passing his CCNA. He was excited. Spent six months studying subnetting, the OSI model, routing protocols. Memorized everything. Passed the exam. First week on the job, a switch went down. He started talking about spanning tree and VLAN configurations. IT manager asked if anyone had checked the power cable. It was unplugged. He said that wasn't covered in the CCNA. Next week, users couldn't print. He started checking IP addresses, subnet masks, and default gateways. Someone turned the printer off. He said printer maintenance wasn't his job. A router started dropping packets. He opened his notes on BGP and OSPF. I asked if he'd checked the interface counters. He said he didn't spend months studying networking to troubleshoot basic issues. I told him that's literally what troubleshooting is. Then he spent two hours designing a redundant OSPF topology for a five-person office. The IT manager asked why. He said high availability. The manager said we have one ISP, one router, and no budget for redundancy. He printed the topology, framed it, and put it on his desk. Now, whenever something breaks, he looks for a complex networking problem to solve. Meanwhile, the rest of us are checking cables, reading logs, verifying configurations, and asking users what changed. Six months later, he still has the framed topology. The office still has one router. And the printer is still turned off every other Tuesday. But at least someone in the office knows OSPF.

It's not just about passing the CCNA. You need to understand what you're learning and how to apply it in real-world situations. If you want to learn networking the right way from someone with over 15 years of industry experience, check out @mmusaktk and his upcoming CCNA class. Details below.
I think I just found the perfect opportunity for anyone working towards their CCNA. @mmusaktk is starting a 2-month live CCNA class this Saturday, October 31. Here's what you get: - Complete CCNA coverage: ITN, SRWE, and ENSA - Live weekend sessions with Packet Tracer and CML labs - Class recordings and AI-generated summaries - Bonus courses on Subnetting Mastery and Data Center Foundations - Eligible students can earn a 58% CCNA exam voucher through Cisco Networking Academy requirements. The class is normally $100, but the first 20 registrations get it for $75 with code CCNA25. If you're serious about getting your CCNA, check out the details below. Registration: LearnWithMoosa.com

If you're planning to take the CCNA exam, pay attention to this. Cisco is updating the CCNA exam on February 3, 2027. If you've been putting off your preparation or struggling to figure out where to start, this is a good time to get serious about it.

CCNA 58% discount vouchers are life savers for students struggling financially.

80% on the CCNA final exam. Still no voucher. Here’s why. ⚠️ A student messaged me this week asking why their 58% CCNA discount voucher never arrived. They scored 80/100 on the ENSA Final Exam, well above the 70% mark. But look at the attempt number: 2. That’s the whole problem. πŸ“Œ How the Netacad CCNA voucher actually works: βœ… You must pass the ENSA (Enterprise Networking, Security, and Automation) Final Exam

I have jumped on the bandwagon and installed #Omarchy on old ACER all-in-one PC. Quick and easy install, everything works, bluetooth keyboard and Wifi. No surprises. The focus on keybaord shortcuts makes a lot of sense, i need to get hand of it. I think i ll be working more.

A researcher was able to find out that Priv key was 4 is the actual problem.
so what if the private key is 4? isn't that technically as likely as any other private key? if you altered the generation to check that it doesn't have too many zeroes, wouldn't this make it less secure?

Friends I need some help. I need a freelancer for a remote role with a US company which means basically no taxes. I know these guys. They are smart people. You will learn a lot. Please DM me resumes. Compensation is 3 lacs. For highly skilled candidates more: Full Stack Engineer β€” Incompleteness, Inc. Incompleteness, Inc. is hiring a Full Stack Engineer with a strong DevOps and security backbone. You will build product features end to end β€” UI, APIs, data β€” and own the infrastructure they run on: the pipelines that ship them, the monitoring that watches them, and the security posture that protects them. Our systems serve tens to hundreds of thousands of concurrent users and increasingly face enterprise security review, so reliability and hardening are core to the job. Working familiarity with the common LLMs and the harnesses around them is expected, but this role's center of gravity is operations and security, not model work. About Incompleteness, Inc. We are a small- to mid-sized company offering advanced cyber security solutions to enterprise clients. We are past the prototype stage: our systems run in production for real customers, and the next phase is scaling them to enterprise grade without losing the speed that got us here. The engineering team is small, senior, and close to the product β€” there are no layers between you and the decisions that matter. What you'll do β€’ Build product features end to end: responsive frontends, API and service layers, and data models. β€’ Own the deployment pipeline: CI/CD, environment management, infrastructure as code, and zero-downtime releases. β€’ Run production: observability, alerting, incident response, and postmortems β€” you instrument what you ship and keep it up. β€’ Harden the platform: authentication and authorization, secrets management, dependency and supply-chain hygiene, encryption, and least-privilege access. β€’ Support enterprise security reviews and lay the groundwork for compliance (SOC 2 / ISO 27001). β€’ Keep our LLM-backed services operable: deploy, monitor, rate-limit, and secure them like any other production dependency. What we're looking for β€’ Solid full stack experience shipping production web applications: a modern frontend framework, backend services (Node, Python, Go or similar), and relational or document data stores. β€’ Strong DevOps fundamentals: containers, Kubernetes or comparable orchestration, a major cloud (AWS, GCP or Azure), infrastructure as code (Terraform or similar), and mature CI/CD. β€’ Security-minded engineering: OWASP-level application security, secure SDLC practices, secrets management, and identity/network basics β€” you have found and fixed real vulnerabilities, not just read about them. β€’ Enough distributed-systems awareness to keep services healthy under heavy concurrent load: async patterns, queues, caching, rate limits. β€’ Working familiarity with the common LLMs (Anthropic, OpenAI, Google, open-weight models) and harnesses β€” enough to deploy, monitor and secure LLM-backed services confidently. β€’ Comfort with ambiguity: you thrive with little structure, shifting priorities, and no spec β€” and you ship anyway. β€’ Clear communication in a small, fast-moving team. Nice to have β€’ SOC 2 or ISO 27001 preparation, penetration-test remediation, or bug-bounty triage experience. β€’ SRE background: SLOs, error budgets, load and chaos testing. β€’ Experience with enterprise readiness: multi-tenancy, SSO/SCIM, audit logging, data residency. β€’ Deeper AI-stack experience: RAG pipelines, evals, or prompt-injection defenses. β€’ Cost optimization across cloud and inference spend. How we work A candid note on fit. We are deliberately light on structure: few meetings, no formal roadmap ceremonies, and priorities that can change week to week as the AI landscape moves. If you do your best work with clear specs, stable requirements, and defined swim lanes, this role will frustrate you. If you like owning a problem end to end, making calls with incomplete information, and building the structure only where it earns its keep, you will do well here. We value shipped software over polished plans, and direct communication over consensus-building.
