Another hands-on project!
I connected Microsoft Entra ID to AWS and tested user onboarding and offboarding.
One key lesson: disabling an account isn't enough. Revoke sessions and verify access!

Let's play, we are doing the CCNA in 90.Fun fact comes with a free 58 percent discount.
@akintunero the one I call Aquaman forces me to make network engineers better.
Do a pretty please.
Maestro is on the beat.
Perception would definitely change.

I took some time off to build something for people learning networking and preparing for their first roles in tech.
Introducing Broken NetLabs
A collection of broken network labs for aspiring Junior Network Engineers, Data Centre Network Engineers, NOC Engineers, and anyone looking to build real-world troubleshooting skills.
Download a lab, find the faults, fix them, and document your solutions in public. You'll also sharpen your technical documentation skills along the way.

Happy troubleshooting! Feel free to share this with someone in your network who could benefit from it.

CCNA tip: access vs trunk ports
Access: connects an end device, one VLAN, no tags.
Trunk: links network devices, carries many VLANs over one cable using 802.1Q tags.
A trunk only carries VLANs. The L3 switch routes between them.

A few years ago, I got hit with layoffs.
I couldn't find a job. I was applying everywhere. My network try to help me. I was getting interviews but I couldn't get an offer letter.
When I couldn't find a job. Being let go was the greatest thing that ever happened to me. Talk about random timing. God gives you something on his time not your time. You can have faith and hope for the best but he works on his time. He will give you what you need at the right time.
I was hit with layoffs and I ended up being a speaker at Romania 🇷🇴. I honestly did not want to go. My confidence was at a all time low. My friend convinced me to go.
By the time I left Romania, I was offered a job.
I got a job by the time I came back from traveling and speaking.
Miracles happen at the right time. I pray that you find your next opportunity this week.
That's my TedTalk for today. I hope this motivates you.
Have a good week!

@Apple lancera le Touch MacBook en octobre, peut-être la dernière semaine du mois.
Vous arrivez en retard ? Je ne pense pas, j’ai appris des produits existants et pour faire de meilleurs produits, oui vous pouvez compter là-dessus ✅

@Apple will debut the touch MacBook this October, possibly last week of the month.
Coming late? Don't think so, learnt from existing products and to make better products, yes you can bank on that ✅

"Victor, you are worse than a salary earner. Your source of income is from one customer, and it is not stable." - Theo Amadi, 1995.
Those words proved true: the business failed some years later, not only due to overreliance on a single customer and a lack of scale, but also due to inexperience.
Three decades later, I am seeing the same mistake repeated by others, and I still sometimes default to the same pattern myself out of habit.
You must sell and sell to many regularly. No single customer is big enough for a business to stop selling to others. Getting large clients and focussing too much on them always seems pragmatic, but it is the most dangerous thing to do when you are small and replaceable.
The modern-day version of one customer is also focused on using a single sales or marketing channel. Millions of people are fighting for attention on TikTok, Instagram, and Twitter; your small venture doesn't have to join in the noise unless it has a unique message and following. This is where so many people (myself included) typically get it wrong.
My cousin, who sells bedsheets and household goods, once told me that even though he has millions of followers on other platforms, his highest conversion and sales come from LinkedIn.
It is a cringy place that we all dump on all the time, but most of my inbound private consulting bookings have surprisingly come from there. What I do these days is test things and perfect them here before I take them to LinkedIn.
This is a million dollars in consulting advice given for zero cents.

Things I have done with AI agents in the last week.
1. Downloaded videos from social media links without using any third-party apps or sites. Savings: time and money.
2. Connected an agent to my bank account through Plaid and stopped paying for RocketMoney Premium. - Saved: $14
3. Appointments - Did meeting preparation with @bot that flagged that a person I was meeting was linked to illegal activity in the past. I didn't ask it to do it. It kept researching the meeting, flagged it an hour before, and gave me time to research, confirm it, and call it off. Savings: unquantifiable.
4. Domain sale negotiation and trademark research. @bot did research on a domain I already own, identified a potential buyer, then found his email and drafted an email. I sent it off to him after Bot flagged that their trademark had expired.
5. Intinct helped me to set a reminder to send a love note to my wife at least once a week and to book a date.
6. Investing - @bot updated my Stock Watch to warn me before scheduled company events and announcements so that I can catch shifts before they happen and not react to news after it has been announced. Opportunity - immense.
7. Setting up Hermes this weekend and will likely use it to get multiple models to work on a project.
I am also looking for every subscription or service I use that can now be replaced with agents. What have you done with AI agents in the last week?
