I intend using it in Lagos in two months time after I get accomodation would I be able to access the residential plan again

Just don’t pay and you will be disconnected
DataMina: 11:11pm On Apr 18
Hello everyone, I have a question.Two questions actually.

I’m currently on the Starlink residential plan, and I’d like to know if it’s possible to write to Starlink to temporarily suspend my subscription and have it restored in about two months. This is because I’m planning to relocate from Rivers State to Lagos, and I need some time to sort out my accommodation and settle in.

Also, I’d appreciate it if someone could clarify whether I’ll be able to continue using the residential plan in Lagos. I’ve heard that Lagos might be congested and may not have enough bandwidth availability for new or existing s on the residential plan.

Get a PC with a graphics card. Ram of 16gig should be enough

Isn't software testing tied to other Software engineering🤔 and why would you chose to learn the skill in isolation?

What you said about data analytics is relatively true but what actually helps me is my natural love for data. Everything about data gets me excited. Since I started as an analyst (with Matlab) during my Post graduate days analysing students and my lecturers data from there I moved to python, R and subsequently Power BI.

Along the line I learnt other side skills like webscraping, data science. Even though I dont have an official job yet the skill I picked up along the cause of learning ensures that I am never short of gigs😊

Towards the end of the first quarter of last year my client introduced me to the cloud that's how I got into data governance and data engineering(bagged dp203 already). These days I am expanding my scope to cloud as I am interested in how data intersects with networks and security ( for a start I am eyeing Azure cloud istration, Az104) and would also focus on getting Databricks data engineering certificate.

So you see, don't allow your mind to limit you. There are other skills linked to software testing or data analytics you can just chose to progress from the skill into other areas. Do not let the fear of a field being saturated discourage you

Due to how lengthy the project was I had to it into about 6 videos. You can go to my post on LinkedIn to check them out👇

I copied the Power BI streaming API and included it in my Python script. In my original Python script I cleaned the data coming from the serial monitor readings to as it had our needed temperature and humidity. I also ensured the data were converted to floats as it needed to match our Json Schema which I created in the power bi endpoint
DataMina: 4:05pm On Feb 25
In Power BI service for you to be able to create the streaming data API you would need to have at least the Power BI Pro or the Power BI Per (PPU) subscription.
My Json Schema has the temperature and humidity field and I also included the Time field which I would also include in my Python modified script to help monitor the datetime when the readings were taken
DataMina: 3:58pm On Feb 25
It is also important you decode the data."utf-8" can be handy here, to remove the byte and carriage return characters. After doing this and running the python code I saw that the data returned in my terminal is exactly the way it was in my serial monitor. With this I got satisfied with what I saw I decide to move over to my Power BI workspace to set up my streaming API and Json Schema
DataMina: 3:55pm On Feb 25
What I did was to disconnect the Port from my Arduino Ide to allow Python access the Port and read data from the Serial monitor.
For python to be able to read the data you would need to install the Pyserial library.
When setting up the python code you also have to ensure that the baud rate matches the baud rate you set prior to when you ed your code to the micro controller
DataMina: 3:52pm On Feb 25
If the verification and ing of the code is successful you can view the temperature and humidity readings through the serial monitor. since i don't have an ESP32 device that would enable me stream data directly to the Power BI API Endpoint directly I had to resort to cheaper means of using Python 😁
DataMina: 3:50pm On Feb 25
So what I did after setting up was use jumper wires to connect the data pin of my DHT11 sensor to digital pin 4 of my Arduino, then connect the live and negative pins of the sensor to the 5V and GND pins of the Arduino. With that in place, streaming the data was almost set

I installed the Arduino IDE and also installed the DHT11 sensor library by Adafruit. You basically don’t need to write your code from scratch since there’s already a prewritten example template you can modify to suit your setup. You really don’t have to be bothered about the code because it’s quite straightforward.

One thing you need to do is ensure that the port through which your PC receives signals is recognized by the Arduino IDE. You also need to select your board as well—mine was the Uno board. To locate the port your Arduino is connected to, you can find it in the **Device Manager** of your PC.
DataMina: 3:40pm On Feb 25
Since I had the Arduino Uno, breadboard, DHT11 sensor, some jumper wires, and a pull-up resistor in stock, I thought about the idea of streaming data to the Power BI Streaming Data API endpoint.

I knew that, by default, Python—being a high-level language—wouldn’t be able to communicate directly with my Arduino device.

Prior to getting into data engineering a few years back, I used to play around with Arduino hobbyist projects, but I abandoned them because I knew me venturing full time in this skill wouldn’t bring in the needed bread.

Check out the GitHub repository for the project here👇

Recently, since I’ve become really comfortable with data engineering, I decided to revisit where I had piled up my hobbyist tools. God being so kind, I wasn’t st*pid enough to throw them away.

To prepare for the exam you have to learn azure data engineering concept first. Like SQL, data lakes, data security, data orchestration, data streaming, data warehousing et al. After which you can now start revising past questions using Microsoft learn and examtopics.

The biggest challenge is getting access to Azure subscription and Microsoft doesn't give Nigerians access to the free trial subscription

Please how can I you I want.to write the exam too, please how did you prepare for the exams?.Any suggestions in of materials.
DataMina: 9:28pm On Jan 14
The Cert cost isn't the problem but you need constant access to Azure subscription.
The problem is Microsoft gives free trial subscription but Nigerians aren't qualified for it

I really don't know why nairalanders keep mistaking me as a bro lol cheesy
I am a lady o.

If you really want to scale through your data warehousing knowledge( using Synapse) + SQL has to be strong
Try as much as you can to revise exam topics questions. Use the Microsoft learn documentation as a reference guide( very important)

Congrats bro. It is nice.. but how was the quetions? I plan to do mine next month..
DataMina: 11:30am On Jan 14
I am very sure this is not genuine because it was created not more than two weeks ago.

Please don't fall for this fraud
DataMina: 11:28am On Jan 14
Stay away from scammers like this promising to sell open AI credit.
Most of the people who sell to this good to be true Azure credits on Nairaland are all frauds.

I am planning to expose one of them who refused to refund my money after I told him I am not interested.

Please do not fall for this scam. At most you can opt to get a free trial Azure .
After I told the nairalander who sells Azure credit just like this good to be true offer this nairalander is offering he refused. Even when he agreed to come on video call he was hiding his face.
If you want to do anything with thess guys they should be ready to show their face.

You have the option of taking it at home or in a Microsoft approved test centre.
To take the test at home you have to meet some conditions so I opted taking it the exam in Pearson Vue center

Where did you take the exam, at home?

The approach forces you to take the cert and the skill serious

Okay... It's a one time payment. Renewal is free.

Better than some that isn't free for renewal
Thank God say higher institutions exist long time ago cause if na now eh - the certs for dey expire after every four four years

You must be ignorant to make that malicious claim that Port Harcourt is majorly Ijaw.
Port Harcourt and it's metropolitan areas are owned by the Ikweres. Even the waterside the Rebis people owns it. You guys are only customary tenants there

richmond500:
Obio/Akpo and Portharcourt are different.

U said portharcourt and I only corrected u that portharcourt is purely ijaw while Obio/Akpo is Igbo. Don't mistake the two
DataMina: 9:26am On Jan 13
You have to keep renewing it every year with 0 cost attached.
The cert isn't free. Microsoft charge Nigerians 80 dollars for it
preciouswoman66:
Congratulations to you smiley
SQLwas my strength when I took certification exam from datacamp. I didn't pay for the certification, it was sponsored by I4G

Is the certification free? Cause I'm seeing it's expires 1 year later - next year 2026

I’m excited to share that I’ve ed my Azure Data Engineering exam!

I tried so hard to ✍️ this exam last year, but distractions here and there wouldn’t let me. My target was to score above 90%, but Microsoft flipped the script with questions I didn’t even bargain for 😔. Honestly, if it wasn’t for my solid SQL knowledge, I wouldn’t have scaled through.

As expected, data warehousing with Synapse made up the bulk of the questions, but I was surprised to see quite a number of questions on Azure Stream Analytics. To my surprise, there wasn’t a single question on Purview either.

I am really looking forward to the opportunities that comes with my data engineering skills

Hi guys have got good news for you.
I have been able to my Azure data engineering exam.
Although I have been preparing for this for the past 9 months the way most of the questions were framed was not what I expected. What helped me was I was 100 percent certain I got all the case studies questions correct and my command of SQL is really sound
As usual data warehousing using Synapse formed a huge chunk of the question I was surprised that I had a lot of stream analytics question.

My next cause of action now is to start creating short content with target to LinkedIn recruiters
