How To Make Sure Your Engineering Manager Gives You The Proper Credit

So many software engineers are frustrated with the amount of credit their manager gives them, especially during performance review. Watch this video to ensure that this never happens again.

Here are the core points from the video:
- **Assume that your manager doesn't know what you're doing** - Engineering managers are *extremely* busy, and they are unfortunately more busy the higher quality they are (i.e. more people will want to book meetings with them if they are good). A lot of the time, they simply won't have the time to proactively scan what you're doing - They aren't unaware of your impact/problems due to bad intent.
- **Alert your manager of important events**
  - cc them on communications (Slack/Teams message, emails) and documents
  - Put them as optional on meetings (they may even want to join if it's an important meeting)
  - Share in 1:1 meetings (this is the most powerful medium)

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
```

```
summing_squares(31) # -> 4
```

Part 3 [RBP] Clean Up Your Effects

This lesson emphasizes the crucial practice of cleaning up side effects in React components to prevent unexpected behavior and optimize performance.

- **Understanding useEffect Cleanup:** Learn how to use the cleanup function returned by `useEffect` to properly handle resources like network connections, event listeners, and subscriptions.
- **Avoiding Memory Leaks and Unexpected Behavior:** Discover how neglecting cleanup can lead to memory leaks, multiple event triggers, and other unintended consequences, especially when components mount and unmount frequently.
- **Debugging with Strict Mode:** Explore how React's Strict Mode helps identify potential issues by intentionally double-invoking effects in development, making it easier to spot missing cleanup logic.

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
```

Asking Great Questions [Part 13] - Please Don't Do This: Leading Hello

A lot of what we're taught growing up doesn't translate very well into the software engineering world, and how we greet people is one of those things. This lesson teaches you:

- Why a standard solitary "Hello" or "Hi" is a terrible way to get help digitally
- What being polite actually means in the engineering world
- What you should do instead of leading hello

Mid-Level Engineer (L4) Describes Most Important Skill - Dipika Tiwari

Dipika is a mid-level engineer at Qualcomm.

- **Most important skill**: efficient log analysis. Being able to quickly make sense of the bug report and provide actionable next steps is critical for productivity and trust. 
- **Advice**: keep notes as you ramp up, since that information will likely be useful later on.

How Rigid Should You Be With Your Coding / Content Schedule?

As a 17 year veteran of Amazon, Steve understands seasonality. Q4, the holiday season, is crunch time. There’s a huge pressure on Amazon employees to keep up with demand, and engineers will routinely spend long hours to ensure stability and quality.

The key to doing sustained creative work is to lean in and lean out of periods of intense work, at the right times. Amazon employees know that Q4 will end, and therefore, the crunchtime will end within a few months.

Similarly, for content creation or writing code, **it’s important to segment your schedule into chunks where you can create a deadline or “crunch time”.**

Another perspective is to think about quantity vs quality. For your side projects or content creation endeavors, it’s worth being rigid for a bit (“a commit everyday” or “a video every week”), but it’s also worth changing the routine after some time.

Burnout happens when people don’t see an end in sight from a stressful period.

Ace The ML System Design Interview [Part 5] - Modeling

Modeling plays a critical role in machine learning system design, with classification and regression being the most frequently encountered problem types in interviews. Here are the core points from this lesson:

- Understand various evaluation metrics, such as precision, recall, F1 score, NDCG, and loss metrics like cross-entropy and focal loss, and know when to apply each
- Be prepared to discuss trade-offs between metrics, particularly precision and recall, and avoid over-optimizing for a single metric
- Recognize the significance of loss metrics, memorizing the equations for cross-entropy and focal loss, and understanding their applications in balanced and imbalanced datasets
- Be ready to discuss model selection, including architecture choices like two-tower models or matrix factorization, and anticipate follow-up questions on optimization techniques and troubleshooting issues like overfitting and vanishing gradients
- Consider a baseline model for comparison if no current system exists, and if there is an existing system, use it as a reference point

Become A Debugging Master [Part 8] - Write Down All The Context

One of the easiest ways to massively speed up your debugging (and make yourself look way more senior) is simple: write things down early and often. Here are the core points from the lesson:

- Don’t wait for clarity to write—writing your thoughts down is what *creates* clarity and uncovers next steps
- Always document repro steps, failed attempts, blast radius info, and hypotheses while debugging
- Writing things down improves your retention, narrows the search area, gives credit to others, and makes handing off bugs much smoother
- Even half-baked notes are powerful because they build momentum, reduce confusion, and help you communicate progress to others effectively

Gilad’s Take On Management

In this video, we explore the core responsibility of managers and define what great management truly entails. The speaker provides a clear, actionable definition of management and unpacks each part of it to guide us toward becoming more impactful leaders.

- We learn that **the essence of management is to create a positive and sustainable change in the organization’s performance**, a definition we are encouraged to internalize and apply.
- We embrace the idea that management is a **creative, proactive discipline**, not just a reactive one—our actions should be intentional and forward-looking.
- We are reminded that our impact must be **positive** and **lasting**, focusing on growing people and systems that perform well even in our absence.
- We are taught to focus on **creating deltas**, meaning our value lies in the improvement we drive, not in maintaining the status quo.
- We expand our view beyond just our teams, recognizing that **great managers influence the broader organization**, constantly looking for opportunities to elevate overall performance.

If you want to learn more from Gilad, he shares free leadership advice daily on [LinkedIn](https://www.linkedin.com/in/giladnaor/?utm_source=taro&utm_medium=course&utm_campaign=cta) and weekly on the[ δeltas newsletter](https://posts.managementdeltas.com/?utm_source=taro&utm_medium=course&utm_campaign=cta)
