C++ Arrays: A Guide to Understanding, Storing, and Expanding with Vectors
Published: 2024-02-11 06:38:12

In C++, arrays provide a fundamental data structure for organizing and managing collections of values of the same type. This blog post delves into arrays, explores their capabilities, and guides you through effective usage patterns.

### Understanding Arrays:

- **Concept:** Arrays store multiple elements of the same data type in consecutive memory locations. Each element, identified by its index (starting from 0), can be directly accessed and manipulated.
- **Declaration:** Declare an array using its data type, name, and size enclosed in square brackets:

`data_type array_name[size];`

-**Initialization:** Arrays can be initialized during declaration using curly braces ({}) to provide initial values, or assigned values later.

### Storing Roll Numbers Effectively:

While directly creating individual variables is viable for a few students, arrays become essential for efficient storage and management of larger groups.

### Key Points:
- This snippet dynamically calculates the number of students using the sizeof operator.
- Arrays simplify data organization and retrieval, promoting code readability and maintainability.

### Addressing Array Limitations:

Arrays do have limitations:

- **Fixed Size:** Predefined size can become inflexible if the number of elements changes.
- **Memory Management:** Manual allocation and deallocation can be error-prone, requiring careful attention.

### Introducing Vectors: A Dynamic Array Alternative

C++'s Standard Template Library (STL) provides std::vector, a dynamic array that overcomes these limitations:

Using std::vector:

- **Dynamic Growth:** Add or remove elements at runtime using push_back() and pop_back().
- **Automatic Memory Management:** No manual allocation/deallocation needed, reducing error risks.
- **Iterators:** Simplified access and manipulation of elements using iterators.

### Conclusion:

Choose arrays when the size is known at compile time and memory management is straightforward. Opt for std::vector for scenarios with dynamic data requirements and flexibility concerns. By understanding their strengths and weaknesses, you can make informed decisions and leverage these data structures effectively in your C++ programs.

Decorator Functions in Python: Enhancing Functions Dynamically
Tags: programming, tutorial, beginners, python
Published: 2024-02-11 06:05:00

Decorator functions in Python serve as dynamic enhancers for our functions, allowing us to add extra features seamlessly and preventing code redundancy. They find extensive use in Python frameworks like Django.

## Key Benefits of Decorators:
**Modularity:** Decorators promote modularity by allowing developers to encapsulate specific functionality and apply it consistently across multiple functions.
**Code Reusability:** They eliminate the need for duplicating code to add similar features to different functions, ensuring cleaner and more maintainable code.
**Readability:** Decorators enhance code readability by keeping the core logic of functions clean and separating additional concerns, making the codebase more understandable.
**Framework Integration:** Widely employed in frameworks like Django, decorators seamlessly extend functionalities for database operations, view handling, and more.

Professional Example:
Consider a decorator that logs the execution time of a function:

```
import time

def timing_decorator(func):
    def wrapper(*args, **kwargs):
        start_time = time.time()
        result = func(*args, **kwargs)
        end_time = time.time()
        execution_time = end_time - start_time
        print(f"Execution time for {func.__name__}: {execution_time} seconds")
        return result
    return wrapper

@timing_decorator
def example_function():
    # Some time-consuming operation
    time.sleep(2)
    print("Function executed successfully")

example_function()
```

`Function executed successfully
Execution time for example_function: 2.001079797744751 seconds`

1. The timing_decorator function takes another function (func) as its argument and returns a new function (wrapper) that includes additional functionality.
2. The wrapper function calculates the execution time of the decorated function and prints it.
3. The @timing_decorator syntax is a convenient way to apply the decorator to the example_function.
4. When example_function is called, the decorator prints the execution time in addition to the function's output.

This example illustrates how decorators enhance functions with reusable and modular functionality. They provide a powerful tool for extending the behavior of functions in a clean and organized manner.

The most odd thing

Published: 2024-02-11 05:55:00

## Weekly Challenge 255

Each week Mohammad S. Anwar sends out [The Weekly Challenge](https://theweeklychallenge.org/), a chance for all of us to come up with solutions to two weekly tasks. My solutions are written in Python first, and then converted to Perl. It's a great way for us all to practice some coding.

[Challenge](https://theweeklychallenge.org/blog/perl-weekly-challenge-255/), [My solutions](https://github.com/manwar/perlweeklychallenge-club/tree/master/challenge-255/sgreen)

## Task 1: Odd Character

### Task

You are given two strings, `$s` and `$t`. The string `$`t is generated using the shuffled characters of the string `$s` with an additional character.

Write a script to find the additional character in the string `$t`.

### My solution

I have created a function `frequency_count` that counts the frequency of each character in a string.

```python
def frequency_count(s: str) -> dict:
    freq = {}

    for c in s:
        freq[c] = freq.get(c, 0) + 1

    return freq
```

I then calculate the frequency for each letter in both strings. Finally I iterate through each letter in the second string, and return the character where the frequency is higher in the second string than the first.

```python
def odd_character(s: str, t: str) -> str:
    first_freq = frequency_count(s)
    second_freq = frequency_count(t)

    for c in second_freq:
        if second_freq[c] > first_freq.get(c, 0):
            return c
```

### Examples

```bash
$ ./ch-1.py Perl Preel
e

$ ./ch-1.py Weekly Weeakly
a

$ ./ch-1.py Box Boxy
y
```

## Task 2: Most Frequent Word

### Task

You are given a paragraph $p and a banned word $w.

Write a script to return the most frequent word that is not banned.

### My solution

For this challenge, I need to determine what is a word. I use the regular expression `\w+(?:'\w+)?` which will capture words that have an apostrophe in it, like "isn't" while excluding where it is used as a quote start/end. I also convert the string to lower case to catch cases where the word might be in a different case.

With that in mind, I go through the string and count the frequency of all the words in a dict called `freq`.

```python
freq = {}
for word in re.findall(r"\w+(?:'\w+)?", p.lower()):
    freq[word] = freq.get(word, 0) + 1
```

I then remove the bad word (if it exists)

```python
freq.pop(b, None)
```

Finally, I find the maximum frequency, and the word that has that frequency.

```python
max_count = max(freq.values())
words = [k for k in freq if freq[k] == max_count]
return words[0]
```

### Examples

```bash
$ ./ch-2.py "Joe hit a ball, the hit ball flew far after it was hit." hit
ball

$ ./ch-2.py "Perl and Raku belong to the same family. Perl is the most popular language in the weekly challenge." the
perl
```

Finding out that your husband or wife has been unfaithful isn’t just a time of profound heartbreak and shock, it’s also a time of intense confusion . At certain points desperate measures are our only resort and we take them, finding a trustworthy infiltrator can be a lifeline and I sure used one to save my relationship, business and sanity. I was having real life problems when my friend recommended 5ISPYHAK437@GMAIL.COM to me. I contacted him because my business partner was shaking me, stealing money from the business. Also my spouse was always up at odd hours clearly this is a sign that my spouse is cheating, so the hacker cloned/hacked into their devices and granted me total access to their devices without their knowledge. I was overwhelmed that I could see my business partner hidden finances that were off records and read their old and new text messages, see new and deleted pictures, emails, call logs, Facebook, messenger, WhatsApp, Snapchat, GPS location in real time among other things off my spouse phone. If you require the services of a private investigator (EC council certified personnel), you can speak to 5ISPYHAK437@GMAIL.COM  You will be glad you did. For the purpose getting him comfortable working with you, it is advisable you make reference to this post as it would save you a lot of back and forth while ensuring you are not some kid playing around. I do hope this helps.

How to Force Quit Unresponsive Applications via CLI on macOS
Tags: macos, terminal, cli, productivity
Published: 2024-02-11 04:39:55

If you're working on a macOS system and encounter an application that's not responding, you know how frustrating it can be. While the graphical interface offers ways to force quit applications, sometimes you may need or prefer to do this from the command line interface (CLI). Whether you're remote accessing a system, prefer using the terminal, or are in a situation where the GUI is not accessible, knowing how to handle this via CLI can be incredibly useful. Here’s a step-by-step guide on how to force quit unresponsive applications using the command line on macOS.

## 1. Finding the Process ID (PID)

The first step in forcing an application to quit is identifying the process ID (PID) of the application. The PID is a unique number that macOS uses to refer to each running process. There are a couple of ways to find the PID of an unresponsive application:

### Using `ps aux`:

- Open the Terminal application.
- Type `ps aux` and press Enter. This command lists all running processes on the system.
- Look through the list for the name of the unresponsive application. Next to it, you'll see a number, which is its PID.

### Using `pgrep`:

- Alternatively, you can use the `pgrep` command for a quicker way to find the PID. Simply type `pgrep [application name]`, replacing `[application name]` with the name of the program. For example, `pgrep TextEdit` will return the PID for TextEdit if it's running.

## 2. Force Quitting with the `kill` Command

Once you have the PID, you can proceed to force quit the application using the `kill` command.

- In Terminal, type `kill [PID]`, replacing `[PID]` with the actual process ID of the application you want to quit. For example, `kill 12345`.

- If the application doesn’t quit with the standard `kill` command, you can use a stronger signal, `-9`, to force quit. Type `kill -9 [PID]`, for example, `kill -9 12345`. This sends a SIGKILL signal, which immediately terminates the process.

## 3. Using `pkill` to Directly Force Quit

If you prefer not to look up the PID, you can use the `pkill` command to force quit an application by its name.

- Simply type `pkill [application name]`. For instance, `pkill TextEdit` would force quit TextEdit.

### Caution

While force quitting applications can be necessary, it should be done with caution. Unsaved data may be lost, and there's always a slight risk of causing system instability. Always attempt to allow the application to respond on its own or try to close it normally before resorting to force quitting.

## Conclusion

Understanding how to manage unresponsive applications through the CLI can be a powerful addition to your troubleshooting toolkit on macOS. Whether you're a developer, system administrator, or just prefer using the terminal, these commands offer a quick and effective way to regain control over your system when applications freeze or become unresponsive.

Remember, with great power comes great responsibility. Use these commands wisely and always ensure you have saved your work before force quitting any application.

Tags: opentelemetry, kubernetes, observability
Published: 2024-02-11 03:48:05


![kubectl opentelemetry tracing](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pkmwowycg7fc0j3mbp3d.png)


[kubectl otel](https://github.com/agardnerIT/kubectl-otel) is a Kubernetes CLI plugin which will generate OpenTelemetry traces for any `kubectl ...` command you run and output them to a tracing storage backend of your choice.

For example, this command will time how long it takes to apply the `deploy.yaml` file and send the trace to a backend.

```
kubectl otel apply -f deploy.yaml
```

You could also alias it so the tracing is seamless:

```
alias ko='kubectl otel'
ko apply -f deployment.yaml
```

## Prerequisites
- Currently only supports Linux and MacOS
- You must have [a standalone binary of tracepusher in your path](https://github.com/agardnerIT/tracepusher/releases/latest) (ie. you are able to run `tracepusher` from the command line and see output)
- You must have an OpenTelemetry collector somewhere so the spans can be sent there

## Installation

krew listing - [coming soon (hopefully)](https://github.com/kubernetes-sigs/krew-index/pull/3289)

For now:

- Download kubectl-otel
- Make it executable: chmod +x kubectl-otel
- Move it to anywhere in your path (eg. `/usr/local/bin`): `sudo mv kubectl-otel /usr/local/bin`

Try it out: `kubectl otel version` should execute `kubectl version` and trace the time (expected to be quick eg. 0 seconds).

## Code on GitHub

This plugin is [fully open sourced on GitHub](https://github.com/agardnerIT/kubectl-otel). Drop by, submit an enhancement PR and give the repo a ⭐
