Fill your mind with thoughts of peace, courage, and hope. – Dale Carnegie’s Golden Book.

There was a reason why I am not active on Linkedin and now I know why – Join 50,000+ engineers and learn how to crush technical interviews.

You may know about Backstroke, Breaststroke, Butterfly and not be a good swimmer.

I was bold back in the days. Had technical with Yahoo and every answers for the question asked was not correct.

Finally, I replied with, “If you put me on the database and if I cannot solve it, then don’t hire me.”

The interviewers replied with, “You are doing well Michael and we wanted to understand your thought and troubleshooting process.”

Yes! I did get the offer but had already accepted another “=)

Imagine a manager complimenting you, “I sleep better knowing you are at the helm.”
I have been laid off three times in a row now.

The last 2 positions were given to me without any interviews because the managers knows me and my work ethics.

I found this on LinkedIn and is just bad ethics.

I have always said the best part of me is my spouse.

Always do your best because you do not know who is paying attention!

Don’t Know + Don’t Try = Don’t Care.

Remove the don’t and do your best!

What is the difference?

Auto Collection Using TFA (Recommended)
Manual Collection Using Script for Unix

Note: Oracle support typically request TFA; however, some environment disable TFA due to resource.

This means manual collection is required.

Of course, it’s better to have people act because they want to vs have to.

Like everything, it depends.

Going back to the team I led decades ago. When asked to perform a task, I would typically get the same set of volunteers. They are the ones I can always count on.

Unfortunately that’s not the case for my new team. It’s so quiet that one can hear a dog fart.

In a crisis situation, asking for volunteers is not ideal.

A lifeguard resuscitating a person would not shout, “Someone call 911!”

Instead, lifeguard will need to select a specific person.

You! What’s your name. Do you have a phone? If yes, call 911. This create accountability vs having everyone calling 911.

Know the situations!

Cleaning emails from a decade ago to find what I used to have as part of signature.

Confidence comes not from always being right but from not fearing to be wrong – Peter T Mcintyre

Great minds discuss ideas; average minds discuss events; small minds discuss people – Eleanor Roosevelt

If I told you that I am timid, then would you believe me?

I was asked, “If you don’t believe in yourself, then who will?”

I was told by a dear departed friend, Jerry Roberts, to tell yourself, “Every day in every way, I get better and better.”

I was once complimented, “There is a fine line between confidence and cockiness and you walk that line well.”

Believe in yourself and the best you can be.

Good leadership is when people do things because they want to versus have to.

Recently, I was given a position as team lead and it seems I have fallen in the second position (have vs want).

Wondering if I need to make someone cry? Here’s the story for that.

I was promoted to lead at a young age at Puritan Bennet.

The company had 2 strikes with FDA.

Current team lead has made me aware of my short fuse.

First day as a lead, a manager tells me “One of your team member is crying in the corner.”

CRAP! I went to see her and ask what I did wrong.

I was not scolding nor yelling but rather spoke in a calm voice. She then tells me, “I can see the anger in your eyes.”

Thank God for remote work.

They are the best!

To laugh often and much;

To win the respect of intelligent people and the affection of children;

To earn the appreciation of honest critics and endure the betrayal of false friends;

To appreciate beauty;

To find the best in others;

To leave the world a bit better, whether by a healthy child, a garden patch or a redeemed social condition;

To know even one life has breathed easier because you have lived;

This is to have succeeded.

– Ralph Waldo Emerson

I actually have this in my photo album from decades ago.

Received email from Technical Lead | Senior Manager for the following errors.

Error Description: 0: Invalid pool name ‘oraclePool’ while getting a database connection.
Please check for consistency of the properties files or BPML
Time of Event: 20240419141429
Workflow Id: 88867

First inclination is to check Oracle database parameters (sessions and processes) which wasted time on a wild goose chase.

I am by no mean an expert but Google is your friend.

SI fails to startup with error: “Invalid pool name ‘NewPool_oraclePool’ while getting a database connection. Please check for consistency of the properties files or BPML” (SCI91968)

It puzzle me how a Technical Lead | Senior Manager does not know how to Google.

LMGTFY – Let Me Google That For You for all those people who find it more convenient to bother you with their question rather than to Google it for themselves.

With great power comes great responsibility.

Zero-sum is a situation, often cited in game theory, in which one person’s gain is equivalent to another’s loss, so the net change in wealth or benefit is zero.

A zero-sum game may have as few as two players or as many as millions of participants.
