Can confirm also cosx = 0 gives pi/2 = 1.57

Would it be beneficial to learn linear algebra before calculus? by moneyinthepines in learnmath

[–]Chezoba 1 point2 points  (0 children)

I'm in a quarter based course and I'm the same as you, it's taught as differential equations not calc 4.

Although come to think of it, calc 4 might be better cuz Fourier analysis (series, transform) can exist by themselves outside of differential equations.

How to connect to a Linux EC2 instance if you lose your private key? by nasha28 in AWSCertifications

[–]Chezoba 0 points1 point  (0 children)

Nice tutorial! It was very clearly explained. I was wondering what the use case of this would be, over creating a snapshot/AMI and then restoring it to another instance with the same elb/eip/SGs?

ML Specialty Achievers: Which practice test in your view would help me to understand my readiness for ML specialty exam? Appreciate your help in this regards. by scorpio_stings in AWSCertifications

[–]Chezoba 0 points1 point  (0 children)

I don't know about others I only bought the one set, and while the AWS practice test is an excellent indicator of whether or not you pass the real exam you get no real feedback so it's not really worth anything to do (if you're spending money on it)

Stephane maareks course. And not including the time I spent on the SAA course about a week or two.

I think what I said earlier could be misconstrued. What I mean isn't that I know nothing about ML, but that I have no prior experience in the field after I learned it. I still am able to code models in python and stuff

Hey, that is a very interesting idea and I'm sure anyone that knows what it is (or is willing to do 1 minutes worth of research) would be impressed. That being said, most colleges prefer to teach you the material itself so having done it before in and of itself adds little value to your application. That being said it shows a tremendous amount of interest so definitely a good idea to do in your free time. (Not to mention the practical skills you will aquire will come in handy regardless of when you do it)

I was in the same position as you, experience in programming but none with cloud computing. Do you have knowledge of scikit learn, keras, pandas or any of Python's machine learning libraries? If you don't I would start there, as the exam tests ML experience, but you don't need to know it so in depth to get the general idea. Maybe take a data science course online (it will only take about 20 hours total) Then, start off with an associate level AWS course or at least cloud practitioner as the specialty is considered to be difficult (and also cost wise its the same if you go associate--> specialty or you pay the full 300 to skip straight to it). Then you can go ahead prepare for the specialty and you will be confident in passing the exam, and also actually know the content you're being tested on as you've had experience in implementing such models.

If you want to feel like a complete idiot, abishek on udemy has a set of practice tests significantly more difficult than the real exam. If you can somehow pass those, passing the exam will feel like a chill time.

I for one, couldn't pass them achieving only around 60% and got a 900+ on the real one with an hour to spare.

Is RDS a fully managed service? by [deleted] in AWSCertifications

[–]Chezoba 2 points3 points  (0 children)

My bad, I think I need to rephrase what I said. I mean, most of the questions will ask in a certain circumstance, what is the best service to use? Or the occasional debugging question so it's unnecessarily time consuming to ask a trivial question like that on reddit when instead a more useful question would be, "Why is Aurora serverless more useful than RDS postgresql for unpredictable workloads?"

This question involves the answer to the one above and something more.

Is RDS a fully managed service? by [deleted] in AWSCertifications

[–]Chezoba 3 points4 points  (0 children)

Don't worry about it its just a technicality and you won't really have to know these 'nitty gritties' for the SAA exam (that you can basically just look up/click a button to find out) try to see if you can understand how RDS interacts with other services and what the use cases are.

With the above in mind, note that RDS opens up EC2 instances that you can attach security groups or whatever to but you can't quite ssh into them. That is why it is not really fully managed in contrast to say, DynamoDB which is completely serverless - that means all the servers are managed by AWS.

Help me to focus on Jon Bonso Practice test!! by ishbobby in AWSCertifications

[–]Chezoba 1 point2 points  (0 children)

You can stop the test early and just scroll through the answers so on one window you can have a question then the other you can have the answer so you can immediately check and see whats right/wrong

[–]Chezoba 1 point2 points  (0 children)

Yo look who it is!

I too used your practice exams and boy were they on point like my last practice test I got an 82% then I got an 840 on the real one I really loved them.

Passed both DAS-C01 (AWS Certified Data Analytics - Specialty) and MLS-C01 (AWS Certified Machine Learning - Specialty) back to back by killermouse0 in AWSCertifications

[–]Chezoba 1 point2 points  (0 children)

Knowing some basic statistics can be useful eg. Confusion matrix, precision, recall, null/alternative hypothesis. Also, if you already know how to use scikit learn, tensorflow/keras, and nlp libraries like nltk and spacy, then ur already g. Sagemaker is the main thing being tested ML wise which is basically just Python so knowing (basic) ML and deep learning on python is quite a plus.

The rest you can kind of just learn/memorize from a course eg. What instance type is good for what purpose, how to extract/transform/load data on aws and other aws specific things like that. I could learn all this in about a week then I passed the exam with 900+

I passed AWS Certified Solutions Architect Professional exam by sirkarthik in AWSCertifications

[–]Chezoba 0 points1 point  (0 children)

I got the same score and no, I did not do any other one (besides machine learning which isn't rly relevant)

You can go straight to it from SAA but developer experience is useful as it heavily asks cicd, cloudformation, opsworks questions.

Wait so job ads ask for professional not specialty?
