These exams are both fun and a little stressful, but you do learn a lot while studying!!!
Will post the overall score results when I get them!

SSDT 2017 and Backwards Compatibility
If you are working with SSDT 2017 and creating reports for earlier versions of SSRS, please read the following article!
I really think MS did a great job here with the “TargetServerVersion” property functionality, which allows reports to convert to previous SSRS formats during deployment.
AWS Developer Certification – My Plan
Below is my plan to obtain the AWS Developer Certification.
For each of the following areas listed further down, I am trying to do the following:
- Read the FAQ’s
- Practice in the console
- Practice with the CLI and understand the functions\parameters
- Review all HTTP codes
- Review all defaults and limits
- Review uniqueness of each area
Here are the areas I am covering in preparation for the exam.
- EC2
- S3
- DynamoDB
- SNS
- SQS
- VPC
- ELB
- Lambda
- Route 53
- RDS
- SWF
- Cloudformation
- Elastic Beanstalk
- API Gateway
- Storage Gateway
- EFS
- CloudWatch
- CloudTrail
- IAM
The exam is only 55 questions, so i’m not sure how in depth the exam will go on each of these. Regardless, its a good to review all of the areas!
Python – Tesseract – OCR – IMAGE
You can do some pretty cool things with tesseract-ocr. Using PyOCR, which is a wrapper for Tesseract, you can generate text from an image using Tesseract.
Example Image:
Example Output:
Example Code:
from wand.image import Image
from PIL import Image as PI
import pyocr
import pyocr.builders
import io
import sys
reload(sys)
sys.setdefaultencoding('utf8')
tool = pyocr.get_available_tools()[0]
lang = tool.get_available_languages()[1]
txt_list = tool.image_to_string(
PI.open('/home/build/aws.jpg'),
lang=lang,
builder=pyocr.builders.TextBuilder())
outputFile = open('output.txt', 'w')
for item in txt_list:
outputFile.write("%s" % item)
outputFile.close()
Another use case I was working on today was rendering the text in a PDF file using Tesseract. I was converting the PDF to an image file first, then performing the above actions to read the text from the new image.
Here are a couple valuable resources I used to complete this little test.
- Installing Tesseract on a RHEL system – http://www.keienberg.com/install-tesseract-3-04-centos-7/ (link)
- Installing PyOCR and other image conversion tools – https://pythontips.com/2016/02/25/ocr-on-pdf-files-using-python/ (link)
Getting all the prerequisites installed was by far the hardest part on this effort.
