Dynamic programming: Teach me like I am 5!
Published: 2024-07-17 01:00:08

Imagine you have a magical notebook 📓✨. This notebook remembers answers to problems you’ve already solved so you don’t have to solve them again.

Let’s start with something simple: climbing stairs. Each time, you can either take 1 step or 2 steps. How many ways can you climb to the top if there are n stairs?

Magical Notebook to the Rescue!

Define the problem: To find the number of ways to reach the nth step.
Remember the simple problems: The number of ways to get to step 1 is 1, and to step 2 is 2.
Steps:

If you’re on step 1, there’s only one way to stay there.
If you’re on step 2, there are two ways: step 1 to step 2, or jump directly to step 2.
For step 3 and beyond, you can either come from the step right before it (n-1) or jump from the step two before it (n-2).

Let’s write this in code:
`def climbStairs(n):
    if n == 1:
        return 1
    elif n == 2:
        return 2
    else:
        steps = [0] * (n + 1)
        steps[1] = 1
        steps[2] = 2
        for i in range(3, n + 1):
            steps[i] = steps[i - 1] + steps[i - 2]
        return steps[n]


print(climbStairs(5))  # Output: 8`

Another example!
You are in a candy store, and there are different candies in a line. Each candy has a different amount of happiness points. You can’t take two candies next to each other, or you’ll get a tummy ache. How do you collect the most happiness?

Magical Notebook to the Rescue!

Define the problem: To find the maximum happiness you can collect without taking two candies next to each other.
Remember the simple problems: The happiness points for each candy.
Steps:

If you only have one candy, take it.
If you have two candies, take the one with more happiness.
For three or more candies:

Decide to take the current candy and add it to the best of skipping the next candy.
Or skip the current candy and take the best up to the previous candy.
Let’s write this in code:
`def maxCandyHappiness(happiness):
 n = len(happiness)
 if n == 0:
 return 0
 elif n == 1:
 return happiness[0]
 elif n == 2:
 return max(happiness[0], happiness[1])
 else:
 max_happiness = [0] * n
 max_happiness[0] = happiness[0]
 max_happiness[1] = max(happiness[0], happiness[1])
 for i in range(2, n):
 max_happiness[i] = max(max_happiness[i-1], happiness[i] + max_happiness[i-2])
 return max(max_happiness)
happiness = [3, 2, 5, 10, 7]
print(maxCandyHappiness(happiness)) # Output: 15`

Why Use Dynamic Programming?
It saves time! Instead of doing the same work over and over, your helper remembers the answers and by remembering small answers, your helper can find the best way to solve the big problem!

Hope this helps!

Code Reviews and Recommendations:

Code Quality: CodeGuru Reviewer analyzes your code as you develop and provides recommendations to improve code quality. It identifies issues such as resource leaks, incorrect concurrency usage, and security vulnerabilities based on AWS best practices.
Automated Feedback: Instead of relying solely on manual code reviews, CodeGuru offers automated feedback in real-time, helping you catch potential issues early in the development cycle. This can significantly speed up the development process and reduce the risk of deploying faulty code.
Performance Optimization:

CodeGuru Profiler: CodeGuru Profiler helps optimize the performance of your applications running on AWS. It uses machine learning to analyze runtime behavior and identify the most expensive lines of code, inefficient use of resources, and opportunities for optimization.
Recommendations: Based on its analysis, CodeGuru Profiler provides actionable recommendations to improve application performance, such as optimizing database queries, improving memory usage, or reducing compute resource consumption.
Integration with AWS Services:

CodeGuru seamlessly integrates with other AWS services, such as AWS Lambda, AWS Elastic Beanstalk, and Amazon ECS. This integration allows you to optimize your applications specifically for the AWS environment, ensuring that your code performs efficiently and scales effectively.
Learning and Best Practices:

By using CodeGuru, developers can learn AWS-specific coding best practices directly through the tool's recommendations and insights.

Cost Optimization:

Beyond performance improvements, CodeGuru can also help optimize costs associated with running applications on AWS. By identifying inefficient resource usage and providing optimization recommendations, CodeGuru helps developers make informed decisions that can lead to cost savings.
In essence, CodeGuru is a powerful tool for developers working with AWS, offering automated code reviews, performance profiling, and actionable recommendations that help improve code quality, optimize application performance, and adhere to AWS best practices. By leveraging CodeGuru's capabilities, developers can enhance their coding skills, accelerate development cycles, and build more efficient and scalable applications on AWS.
So Easy, Even Your Grandma Could Use It (But She'd Probably Just Knit Instead)

Ever felt like writing an API is like solving a Rubik’s cube with your eyes closed? Same here, until I discovered FastAPI. I mean, who enjoys all that endless configuration and boilerplate nonsense? But then FastAPI came along and made me wonder why I ever bothered with anything else.

The first time I created a complex API using FastAPI, it felt like finding a hidden cheat code in a game. Seriously, I whipped up a fully functional, feature-packed API in no time, with all the boxes ticked: data validation, auto-generated docs, and even async support. It was love at first import.

If you haven’t tried FastAPI yet, you’re missing out on something that makes life so much easier. Here’s why you should give it a go: It’s lightning fast, built on Starlette and Pydantic. So simple to use, thanks to its intuitive syntax and clear documentation, that even a newbie can get an API running quickly. And those automatic interactive API docs? They save you from spending hours on documentation. Plus, the clean and effective dependency injection makes your code modular and maintainable. And with async support, FastAPI lets you write non-blocking, highly efficient code.

So, if you’re still struggling with complicated frameworks, do yourself a favor and try FastAPI. Who knows, it might save you enough time to pick up a new hobby – like knitting. But let’s be real: you’ll probably just end up coding more.

#27 — Group and Summarize A Table Where Every N Rows Consists of A Range by Column
Tags: beginners, programming, tutorial, productivity
Published: 2024-07-17 03:00:41

**Problem description & analysis**:

Below is an Excel table. Every two rows form a range; and in each range, each pair of cells up and down is regarded as a piece of data that stores client and working hours that can be empty.

![original tabel](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kjqltpg5y9ny8j35zf8p.png)

We need to find the hours of work for each client.

![desired table](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/o2dub1mv91y3xa2qvopu.png)

**Solution**:

Use _**SPL XLL**_ to do this:

```
=spl("=E@b(?.group((#-1)\2).conj(E@pb(~)).groups(#1;sum(#2)))",A1:G4)
```
As shown in the picture below:

![result table with code entered](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/o7z2vt0ekfs2rtkz3dmj.png)
**Explanation**:

group()function groups rows and retains the grouping result details. groups() function performs grouping and aggregation; # represents the current sequence number in a sequence, and ~ is the current member of a sequence. E@pb converts a sequence to a table sequence without column headers.
Persistent storage on Heroku
Published: 2024-07-17 03:06:38

Hi All.

Heroku seems like a popular PaaS(compared to Google App Engine or AWS Elastic Beanstalk) for hosting my micro-saas backend.

Now What kind of persistent storage can i use that is affordable?

I dont want to use a database like Postgres or MongoDB but want something that looks like a filesystem.

Between AWS S3 and Filestack which would prove to be a cheaper option for a small enterprise?

Infact what is a popular option in the startup community??

Thanks
