Come Up With 500k+ User Project Ideas [Part 5] - Tech Stack Rankings

Machine learning, web, back-end, DevOps, mobile - There are so many different tech stacks software engineers can specialize in. So how does the type of engineer you are affect your side project potential? This lesson teaches you:

- The rankings for tech stacks when it comes to side projects, starting from which one is the best suited and which ones are the worst suited
- Why mobile engineers in particular are extremely well-positioned to build impressive side projects
- The unfair advantage front-end engineers have when it comes to building side projects and getting credit
- Ideas for non-front-end engineers to build great side projects
- The pros and cons of every tech stack when it comes to side projects

Come Up With 500k+ User Project Ideas [Part 4] - Finding Inspiration

Good side project ideas don't grow on trees, but finding them actually isn't that difficult. This lesson teaches you:

- The mentality you should have with your day-to-day life to organically stumble into great software product ideas
- How frustration in general is actually a blessing in disguise, not just for side projects but for engineering in general
- Tactical ways you can improve on existing products in your life

Come Up With 500k+ User Project Ideas [Part 3] - The Key To A Great Project Idea

Most engineer resume projects are half-baked school projects or wrappers around basic tutorials, lacking the necessary continuity to be impressive and get users. This lesson teaches you:

- The #1 cause of death with engineer side projects
- The key that every good side project idea needs to even have a chance of being successful
- What it means for a side project idea to satisfy that key, explained with a concrete example showing the inspiration behind Alex's Random Name Picker app, which has over 1.1 million users

Come Up With 500k+ User Project Ideas [Part 2] - What Makes A Project Valuable

Most engineers optimize for the wrong thing when they build personal software projects, which is 99% of engineer portfolio projects don't matter at all. This lesson teaches you:

- The only metric that matters when it comes to the quality and impressiveness of your side project
- Why getting actual users supercharges the learning and growth you get from building a side project, far more than choosing the best "modern" tech stack ever could
- Common traps engineers fall into that make their side project meaningless, especially when it comes to recruiting

Come Up With 500k+ User Project Ideas [Part 1] - How This Course Works

Are the projects on your resume not helping you at all when it comes to impressing hiring managers and getting job opportunities? Let's fix that. Here are the core parts of the lesson:

Link to Paper: [**https://www.vldb.org/pvldb/vol17/p3731-schulze.pdf**](https://www.vldb.org/pvldb/vol17/p3731-schulze.pdf)

This paper presents an overview of ClickHouse, a popular opensource OLAP database designed for high-performance analytics over petabyte-scale data sets with high ingestion rates. Its storage layer combines a data format based on traditional log-structured merge (LSM) trees with novel techniques for continuous transformation (e.g. aggregation, archiving) of historical data in the background. Queries are written in a convenient SQL dialect and processed by a state-of-the-art vectorized query execution engine with optional code compilation. ClickHouse makes aggressive use of pruning techniques to avoid evaluating irrelevant data in queries. Other data management systems can be integrated at the table function, table engine, or database engine level. Real-world benchmarks demonstrate that ClickHouse is amongst the fastest analytical databases on the market.\
\
We will go into the details of why and how Clickhouse is one of the fastest OLAP database, its underlying storage engine, and the overall philosophy for performance.

Paper Reading: Adaptive Radix Tree - ARTful Indexing for Main-Memory Databases

**Session Led by:[ Dharin Shah](https://www.linkedin.com/in/dharinshah/)**

**Link to Paper:[ ](https://db.in.tum.de/%5C~leis/papers/ART.pdf)[https://db.in.tum.de/\\\~leis/papers/ART.pdf](https://db.in.tum.de/~leis/papers/ART.pdf)**

This paper reading session, we will deep dive into a in-memory optimized index structure, that leverages modern CPU caches to make IOPS faster, also allowing range queries.

Abstract—Main memory capacities have grown up to a point where most databases fit into RAM. For main-memory database systems, index structure performance is a critical bottleneck. Traditional in-memory data structures like balanced binary search trees are not efficient on modern hardware, because they do not optimally utilize on-CPU caches. Hash tables, also often used for main-memory indexes, are fast but only support point queries.

DSA Crash Course [Part 85] - Array Stepper Approach

In this lesson, Alvin explores the strategy to solving the following interview problem:

> Write a function, *array_stepper*, that takes in a list of numbers as an argument. You start at the first position of the list. The function should return a boolean indicating whether or not it is possible to reach the last position of the list. When situated at some position of the list, you may take a maximum number of steps based on the number at that position.
>
> For example, given:
>
> - idx =  0  1  2  3  4  5
> - numbers = \[2, 4, 2, 0, 0, 1\]
>
> The answer is True.
>
> We start at idx 0, we could take 1 step or 2 steps forward.
>
> The correct choice is to take 1 step to idx 1.
>
> Then take 4 steps forward to the end at idx 5.

```
array_stepper([2, 4, 2, 0, 0, 1]) # -> True
```

```
array_stepper([2, 3, 2, 0, 0, 1]) # -> False
```

```
array_stepper([3, 1, 3, 1, 0, 1]) # -> True
```

```
array_stepper([4, 1, 5, 1, 1, 1, 0, 4]) # -> True
```

```
array_stepper([4, 1, 2, 1, 1, 1, 0, 4]) # -> False

In this lesson, Alvin explores the strategy to solving the following interview problem:

> Write a function, *counting_change*, that takes in an amount and a list of coins. The function should return the number of different ways it is possible to make change for the given amount using the coins.
>
> You may reuse a coin as many times as necessary.
>
> For example,
>
> counting_change(4, \[1,2,3\]) -&gt; 4
>
> There are four different ways to make an amount of 4:
>
> 1\. 1 + 1 + 1 + 1
>
> 2\. 1 + 1 + 2
>
> 3\. 1 + 3
>
> 4\. 2 + 2

DSA Crash Course [Part 81] - Summing Squares Approach

In this lesson, Alvin explores the strategy to solving the following interview problem:

> Write a function, *summing_squares*, that takes a target number as an argument. The function should return the minimum number of perfect squares that sum to the target. A perfect square is a number of the form (i\*i) where i &gt;= 1.
>
> For example: 1, 4, 9, 16 are perfect squares, but 8 is not a perfect square.
>
> Given 12:
>
> summing_squares(12) -&gt; 3
>
> The minimum squares required for 12 is three, by doing 4 + 4 + 4.
>
> Another way to make 12 is 9 + 1 + 1 + 1, but that requires four perfect squares.

```
summing_squares(8) # -> 2
```

```
summing_squares(9) # -> 1
```

```
summing_squares(12) # -> 3
```

```
summing_squares(1) # -> 1

DSA Crash Course [Part 79] - Non Adjacent Sum Approach

In this lesson, Alvin explores the strategy to solving the following interview problem:

> Write a function, *non_adjacent_sum*, that takes in a list of numbers as an argument. The function should return the maximum sum of non-adjacent items in the list. There is no limit on how many items can be taken into the sum as long as they are not adjacent.
>
> For example, given: \[2, 4, 5, 12, 7\]
>
> The maximum non-adjacent sum is 16, because 4 + 12. 4 and 12 are not adjacent in the list.

```
nums = [2, 4, 5, 12, 7]
non_adjacent_sum(nums) # -> 16
```

```
nums = [7, 5, 5, 12]
non_adjacent_sum(nums) # -> 19
```

```
