What is an A Player?
Tags: discuss, beginners, career, developers
Published: 2023-11-28 08:59:47

Have you ever asked yourself, why are some people promoted more than others within the tech space? Why are some more hireable than others?

## Enter, the A Player

**So who is the A Player?**

Simply put, the A player (although qualities do differ from person to person), are people that share some key common qualities:

- **Analytical skills and intelligence** – they solve complex problems
- **High energy, proactivity and efficiency** – they get the job done
- **Need for achievement and persistence**– they have a drive to succeed
- **Self-awareness and integrity** – they make teams work better
- **Personal responsibility** – they don’t make excuses
- **Organisation and planning** – they are strong at delivering strategy through action plans

No one is born an A Player, they become one by developing these qualities over time.

I'd love to hear your thoughts.

Types of decision tree in machine learning
Tags: python, machinelearning, programming, tree
Published: 2023-11-28 08:44:12

There are several [types of decision trees](https://www.javatpoint.com/machine-learning-decision-tree-classification-algorithm) used in machine learning, and they vary based on their specific characteristics, objectives, and applications. Here are some notable types:
[You can read in depth about decision tree 
](https://www.javatpoint.com/machine-learning-decision-tree-classification-algorithm)
1. ID3 (Iterative Dichotomiser 3): ID3 was one of the earliest algorithms for constructing decision trees. It uses entropy and information gain to make decisions about splitting nodes.
2. C4.5 (Classification and Regression Trees): C4.5 is an extension of ID3 and is widely used for classification tasks. It uses information gain ratio instead of information gain and can handle both categorical and numerical data.
3. CART (Classification and Regression Trees): CART is a versatile algorithm that can be used for both classification and regression tasks. It uses Gini impurity for classification and mean squared error for regression. CART is the algorithm behind popular tools like Scikit-learn's decision tree implementation.
4. CHAID (Chi-squared Automatic Interaction Detector): CHAID is primarily used for classification tasks. It works by using chi-square tests to determine the most significant variable for splitting.
5. Random Forest: While not a standalone decision tree algorithm, Random Forest is an ensemble learning method that builds multiple decision trees and combines their predictions. Each tree in the forest is trained on a different subset of the data, and the final prediction is made by aggregating the results of individual trees.
6. Gradient Boosting Trees: Gradient Boosting is an ensemble technique that builds decision trees sequentially, with each tree correcting the errors of the previous one. Popular implementations include XGBoost, LightGBM, and AdaBoost.
7. Decision Stump: A decision stump is a very simple decision tree with only one level or depth-one. It is essentially a decision based on a single feature and is often used as a weak learner in ensemble methods.
8. M5: M5 is an extension of C4.5 that includes the ability to handle numeric prediction tasks (regression) as well as classification.
9. Conditional Inference Trees: These trees are based on statistical tests to determine the significance of splits. They are designed to provide more robustness against overfitting.
10. Cost-sensitive Decision Trees: These trees take into account the costs associated withmisclassification. The algorithm aims to minimize the total cost of misclassification rather than simply minimizing the error rate.
Choosing the appropriate type of decision tree depends on the nature of the problem, the characteristics of the data, and the specific requirements of the task (classification, regression, etc.). Each type has its strengths and weaknesses, and the choice often involves a trade-off between simplicity, interpretability, and predictive performance.

What to do if you are not assigned any good projects at work?
Tags: discuss, coding, programming, workplace
Published: 2023-11-28 08:40:29

Yes, we all know that favoritism is a sin. Yet we commit it knowingly or unknowingly on a daily basis. Managers and senior employees also do favoritism.. they assign projects which are good to their favorite employees. So what to do if you are given not-so-great tasks? Or worse, what to do if you are not given any tasks? Here are some things which you can try if you are not given any tasks:

- Try to search for tasks and assign them to yourself and work on those tasks. This lets people know that you work autonomously and it will let them know that you can take initiative.
- Ask for tasks from your manager or the person who usually assigns tasks to you. Let them know that you are free.
- Ask your peers or colleagues if they need help with their tasks or if they have any tasks which they haven't yet started.
- Work on sharpening your skills which are relevant to your job. Obtain online certifications.

Here are some things which you can try if you are given no-so-good tasks:

- First, complete the task which you are given and try to over-deliver. This shows the other person that you have the potential to do more.
- Next, try to ask for a different task which interests you. Let your manager know why you are interested in that task and how your skills would be the perfect fit to complete the task.
- Try to help your colleagues with their task if the tasks which they are doing interest you.

What are your tips on what to do if you are not assigned any tasks or if you are assigned not-so-great tasks at work? Let us know in the comments!
Master One Language, Learn All
Tags: learning, webdev, programming, beginners
Published: 2023-11-28 08:39:56

So, when it comes to diving into the whole coding world, job listings can be a bit overwhelming with their "must know language A" or "must be proficient in language B" demands. Now, people often ask me, "What's the best tech stack to focus on?" My take is pretty simple: pick one you actually like because chances are, someone out there is hiring for it. If you become a pro at it, you'll be in demand, no matter the odds. This way, you won't end up all over the place, switching stacks left and right.

Sure, coding languages have different syntax, but the core concepts remain the same - loops, conditionals, variables, you get the drill. There are tons of paths you can take as a developer, but once you grasp the basics, you can easily adapt them to different languages. It's not a walk in the park, but it's doable and quicker than when you tackled your first language.

Feeling like hopping onto another language? My advice: dive straight into a project. Here's a quick roadmap:

- Figure out what your project needs to do.
- Break it into doable steps.
- Write those steps in plain English.
- Research how to do those steps in your chosen language.
- Code it up, even if it's a bit messy at first.
- Get it working, and then optimize the code.

**P.S:** your go-to resource for learning a new language should be the documentation. Tutorials are cool, but mastering the art of reading documentation will make you unstoppable.

Got an interview for a language you've never touched? No sweat. Cook up a challenging project using the steps above. Trust me, jumping from one language to another will feel like a breeze. But hey, don't spread yourself too thin – aim to be a master of at least one or two. Share your thoughts and approaches in the comments. Good luck out there!

Different Types of Artificial Intelligence (AI)
Tags: ai, generative
Published: 2023-11-28 08:23:04

Artificial Intelligence (AI) is a broad field with several types and functionalities. It can be categorized based on capabilities and functionalities. Let us delve into these categories: 

 

## AI Based on Capabilities 

 

### 1. Narrow AI 

Narrow AI, also known as Weak AI, is designed to perform a narrow task such as voice recognition. These systems operate under a limited set of constraints and are focused on carrying out specific tasks. This is the reality today. What we see in the year 2023 and before does fall under this category.  

The remaining two below are more of a theory and not yet consumable as a product.  

 

### 2. Artificial General Intelligence (AGI)
 

AGI, often called Strong AI, is a type of AI capable of understanding, learning, and applying its intelligence to any intellectual task a human can do. It can understand, interpret, and respond to its environment as a human would. Just to clarify, AGI is not Generative AI.  

 

### 3. Super AI 

Super AI is an AI that surpasses human intelligence and ability. It can perform tasks currently not feasible for humans. This form of AI is not yet present but is the subject of interesting future discussions. 

## AI Functionalities 

### Under Narrow AI 

**1. Reactive Machine AI**

Reactive Machine AI is the most basic type of AI system which cannot form memories or use past experiences to inform current decisions. It reacts to a set of inputs and performs a function. 
 

**2. Limited Memory AI**

Limited Memory AI can make informed and improved decisions by using past experiences stored in its memory. It is capable of learning from historical data to make predictions. 

### Under AGI 

**1. Theory of Mind AI**

Theory of Mind AI is a more advanced type of AI that can understand thoughts and emotions affecting human behavior. It understands that others have beliefs, desires, intentions, and perspectives that are different from their own. 

### Under Super AI 

**1. Self-aware AI**

Self-aware AI is an AI that has evolved to be so akin to the human brain that it has developed self-awareness. Possessing consciousness, this type of AI does not currently exist. 


AI is a fascinating and complex field, with many types and functionalities. As technology advances, we may see the emergence of new types of AI, expanding the possibilities of what AI can do.
What is the -> arrow in Elixir
Published: 2023-11-28 08:12:18

-> is a fundamental part of the Elixir syntax and plays several roles but first what is it. 
The -> arrow is used to denote function clauses, as well as to define anonymous functions.

**1. Defining Function Clauses**
In pattern matching, the -> arrow separates the function head (which includes the function name and its arguments) from the function body. 
For example:

```
defmodule Math do
  def sum(a, b) do
    a + b
  end
end
```

Here, def sum(a, b) do ... end is a function clause, and the -> arrow is implied within the do ... end block.

**Anonymous Functions**
When creating anonymous functions using the fn keyword, the -> arrow separates the arguments and body of the function. 
For example:
```
add = fn a, b -> a + b end
```

In this case, fn a, b -> a + b end defines an anonymous function that takes a and b as arguments and returns their sum (a + b). The -> arrow separates the arguments from the function body.

The -> arrow is crucial for indicating the separation between the arguments and the function body in both function definitions and anonymous functions in Elixir.

# 一、面试经典篇
## 1.合并两个有序数组
给你两个按 非递减顺序 排列的整数数组 nums1 和 nums2，另有两个整数 m 和 n ，分别表示 nums1 和 nums2 中的元素数目。

请你 合并 nums2 到 nums1 中，使合并后的数组同样按 非递减顺序 排列。

注意：最终，合并后数组不应由函数返回，而是存储在数组 nums1 中。为了应对这种情况，nums1 的初始长度为 m + n，其中前 m 个元素表示应合并的元素，后 n 个元素为 0 ，应忽略。nums2 的长度为 n 。
```c++
/*首先思路是双指针法，设置两个指针分别指向两个数组的末尾，对于nums1则是m-1，
然后比较两个指针所指元素的大小，其中大的放到m+n的位置，然后--，然后继续比较
*/
int p1 = 0, p2 = 0;  // 双指针初始化
while (p1 < size1 && p2 < size2) {
    if (条件1) {
        // 处理指针1所指元素
        p1++;
    } else if (条件2) {
        // 处理指针2所指元素
        p2++;
    } else {
        // 处理两个指针所指元素的关系
        p1++; p2++;
    }
}

// 处理剩余元素
while (p1 < size1) {
    // 复制或处理nums1[p1]的剩余部分
    p1++;
}

while (p2 < size2) {
    // 复制或处理nums2[p2]的剩余部分
    p2++;
}
//上述是处理双数组、双指针问题解题模板、其中后面连个while是如何处理剩余元素
```

## 2.移除数组
给你一个数组 nums 和一个值 val，你需要 原地 移除所有数值等于 val 的元素，并返回移除后数组的新长度。
不要使用额外的数组空间，你必须仅使用 O(1) 额外空间并 原地 修改输入数组。
元素的顺序可以改变。你不需要考虑数组中超出新长度后面的元素。
```c++
/*
原地问题一般考虑双指针、快慢指针，快指针用于遍历，慢指针用于获取数组长度
*/

```
