## introduction 
Google search is a powerful tool that can help you find almost any information you need online. However, simply typing a few words into the search bar may not always give you the most relevant or accurate results. 
## Tips
Here are a few tips to improve your Google search skills and find what you're looking for more efficiently:

- Use specific phrases: Instead of using a single word, try using a specific phrase or question. This can help narrow down the results and give you more accurate results.

- Use quotes to search for an exact phrase: If you want to search for an exact phrase, you can put it in quotes. For example, searching for "how to bake a cake" will only show results that contain that exact phrase, rather than results that contain the individual words "how," "to," "bake," and "cake."

- Use a minus sign to exclude a word: If you want to exclude a certain word from your search results, you can use a minus sign (-) followed by the word you want to exclude. For example, if you search for "chocolate cake recipe -vegan," the results will only show recipes for chocolate cake that are not vegan.

- Use an asterisk as a wildcard: If you're not sure of a word or phrase, you can use an asterisk (*) as a wildcard to represent any unknown terms. For example, if you search for "how to make * sauce," the results will show you different ways to make various sauces.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ib9g9baisfjomansh8dh.png)

- Use the "site:" operator to search within a specific website: If you want to search for something within a specific website, you can use the "site:" operator followed by the website's URL. For example, if you search for "chocolate cake recipe site:www.allrecipes.com," the results will only show chocolate cake recipes from the Allrecipes website.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jkhdtk5024d8m7z0g6n7.png)

- Use the "filetype:" operator to search for specific file types: If you want to search for a specific type of file, such as a PDF or PowerPoint presentation, you can use the "filetype:" operator followed by the file type. For example, if you search for "presentation filetype:ppt," the results will only show PowerPoint presentations.

Implement Fibonacci using MIPS
Tags: mips, assembly, beginners
Published: 2022-12-24 05:16:42

You can take [Implement factorial using MIPS](https://dev.to/blueskyson/implement-factorial-using-mips-1ae7) a look before doing this. This was my college's computer organization assignment. I implemented a Fibonacci using the following algorithm:
{% katex %}
F(n) = \begin{cases}  n, & n = 0,1 \\\\ F(n - 1) + F(n - 2), & n \in \mathbb{N} \end{cases}
{% endkatex %}

In MIPS, I use `$a0` as the parameter *n* of *F(n)*. For example, letting `$a0` equal to `10` and jumping to the `fib` label means *F(10)*, and at the end of the recursion, the result will be stored in `$v0`.

```python
main:
    addi $a0, $zero, 10       # let the parameter n be 10
    jal fib                   # jump to fib label, i.e. calling F(10)
    j exit

fib:
    addi $sp, $sp, -8         # allocate 8 bytes to this stack
    sw $ra, 0($sp)            # save the address of the instruction that calls fib label (instruction address)
    sw $a0, 4($sp)            # save the value of n

    slti $t0, $a0, 2          # $t0 is used for conditions. If n < 2 then $t0 = 1, else $t0 = 0
    beq $t0, $zero, L1        # if $t0 == 0 then jump to branch L1
    add $v0, $v0, $a0         # let $v0 add n
    addi $sp, $sp, 8          # let $sp point to upper stack
    jr $ra                    # jump to the next line of the line calling fib

L1:
    addi $a0, $a0, -1         # n = n - 1
    jal fib                   # jump to fib label again, like as calling F(n - 1)
    addi $a0, $a0, -1         # n = n - 1
    jal fib                   # jump to fib label again, like as calling F(n - 2)
    lw $a0, 4($sp)            # recover the value of n
    lw $ra, 0($sp)            # recover instruction address
    addi, $sp, $sp, 8         # let $sp point to upper stack
    jr $ra                    # jump to the next line of the line calling L1
exit:
```

The execution result of the MARS simulator looks like this:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/a7hecevryxuj3qypziaj.jpg)

You can see that the value of `$v0` is `0x37`, 55 in decimal, which is the result of *F(10)*.
Weekly Challenge 196

[Challenge](https://theweeklychallenge.org/blog/perl-weekly-challenge-196/), [My solutions](https://github.com/manwar/perlweeklychallenge-club/tree/master/challenge-179/sgreen)

Oh dear. I was about to commit my code for this weeks solution, and realized at that moment I didn't commit and push my code for last week!

## Task 1: Pattern 132

### Task

You are given a list of integers, `@list`. Write a script to find out subsequence that respect Pattern 132. Return empty array if none found.

Pattern 132 in a sequence (a[i], a[j], a[k]) such that `i < j < k` and `a[i] < a[k] < a[j]`.

### My solution

So there are two concerns I have with this task:

* In the second sentence, there doesn't seem to be a definition of what `a` actually is. I'm taking an educated guess that `a` is an alias of `@list`.
* In the examples "if more than one subsequence found then return the first". First is a very subjective term when it comes to returning a list.

For this task I used the combinations method from [itertools](https://docs.python.org/3.8/library/itertools.html#itertools.combinations) (Python) or [Algorithm::Combinatorics](https://metacpan.org/pod/Algorithm::Combinatorics) (Perl) to generate all combinations of positions (not values) from `0` to one less than the length of the array.

For each iteration, I (numerically) sort the numbers to ensure `i < j < k`. If `a[i] < a[k] < a[j]`, then I print the result and exit. If there is no solution, I print `()`.

### Examples

```bash
$ ./ch-1.py 3 1 4 2
(1, 4, 2)

$ ./ch-1.py 1 2 3 4
()

$ ./ch-1.py 1 3 2 4 6 5
(1, 3, 2)

$ ./ch-1.py 1 3 4 2
(1, 3, 2)

```

## Task 2: Range List

### Task

You are given a sorted unique integer array, `@array`.

Write a script to find all possible Number Range i.e [x, y] represent range all integers from `x` and `y` (both inclusive).

Each subsequence of two or more contiguous integers.

### My solution

For this task, I iterate over a list (an array in Perl) until it is empty. For each iteration, I pop the first value off the list, and store this as `start` and `end`. I have an inner loop that adds one to `end` if the next value in the array is one more than the current `end`. If `start` and `end` are different, I store this in the `solutions` list.

Then it's just a mater of print the `solutions` list, or a message if no subsequences is found.

### Examples

```bash
$ ./ch-2.py 1 3 4 5 7
[3,5]

$ ./ch-2.py 1 2 3 6 7 9
[1,3], [6,7]

$ ./ch-2.py 0 1 2 4 5 6 8 9
[0,2], [4,6], [8,9]
```
An Introduction to Software Development Methodologies
Published: 2022-12-24 05:00:00

Software development methodologies are frameworks for organizing and managing the software development process. They provide a structure for teams to follow as they plan, develop, and deliver software products. In this post, we'll take a look at some common software development methodologies and their key characteristics.

Waterfall: The waterfall methodology is a linear approach to software development that follows a strict sequence of steps, with each step building upon the previous one. This approach is best suited for projects with well-defined requirements and a fixed scope. 

Agile: The agile methodology is a flexible approach to software development that emphasizes rapid iteration and continuous delivery. Agile teams work in short cycles, called "sprints," and regularly reassess and adjust their priorities based on feedback from users and stakeholders. 

Scrum: Scrum is a specific type of agile methodology that emphasizes transparency, inspection, and adaptation. It involves cross-functional teams working in short iterations to deliver incremental value to customers. 

Lean: The lean methodology is a philosophy that emphasizes continuous improvement and the elimination of waste. It focuses on maximizing value and minimizing waste in all aspects of the development process, including design, development, and testing. 

Kanban: Kanban is a visual method for managing and optimizing workflows. It involves creating a visual representation of the work being done, and using this representation to optimize the flow of work and identify bottlenecks. 

Conclusion

Software development methodologies provide a framework for organizing and managing the software development process. Different methodologies are better suited to different types of projects and organizations. By understanding and applying the appropriate methodology, teams can more effectively plan, develop, and deliver software products.
Life after Windows: was changing to Apple Mac M1 worth it?
Published: 2022-12-24 05:00:00

I have fully converted over to the dark side. Everything I grew up hating or newly looking down at I have now fully embraced. I own a MacBook. To be specific it's just a MacBook air m1. I didn't see any reason in getting the more expensive version of the laptop and I'm glad I didn't.

I like the laptop for the most part. Honestly, the trackpad is the biggest plus. I can just use it, I never think about "Am I right-clicking?", it just works. And I think that is what the biggest draw to the mac ecosystem is, it just works.

When I was in high school and most of my college years I looked down on mac users, thinking they paid an extra thousand for a logo and got nothing more. I am glad that I have moved away from this thinking, I don't think playing down something you haven't used or understood is incredibly foolish. And I guess I am paying for those years.

Now don't get me wrong, I will love and use windows. But I think it falls short in the form of a laptop. I think when you are mobile and entering unknown places, it is best to have something that will not fail you. My new laptop has an actual battery life, it lasts me a day of consistent use. The keyboard feels nice and inviting to type on, which as a programmer helps me write more code.

Now, with all these wonderful things to say about Apple. There are downsides: first is that the CPU is a largely unsupported architecture. Now at the time of writing this, most apps do run on ARM and for the most part, I have had no issues with daily use. But when I'm programming is when the issues surface.

In one of my classes, I was asked to write a program that reads an excel sheet. pretty basic and simple task. One of the libraries that the package we were learning about didn't support the m1. I tried to explain to my teacher what was going on and she was frustrated, cause this wasn't an easy problem to solve. She was a smart teacher (one of my favorites honestly) but she wasn't aware of the new architecture and the problems it would bring. Her solution was for me to go get a different laptop. Not the most elegant solution...

Conclusion:

I enjoy having my Apple Macbook m1, and though it has caused some problems in my programming they have been problems that I can solve.
The role of software metrics in embedded software development
Published: 2022-12-24 05:00:00

Software metrics are measurements of specific characteristics of a software system. They are used to evaluate the quality, complexity, and performance of software and to identify potential issues or areas for improvement. In the context of embedded software development, metrics are particularly important as they help developers ensure that their software is reliable, efficient, and fits within the constraints of the target hardware platform.

One common metric used in embedded software development is code coverage. This metric measures the extent to which the source code of a program has been exercised by a given test suite. A high code coverage indicates that the majority of the code has been tested, which can increase confidence in the software's reliability. However, it is important to note that high code coverage does not necessarily guarantee that the software is free of defects.

Another important metric is cyclomatic complexity, which measures the number of linearly independent paths through a program's source code. A high cyclomatic complexity can indicate a complex or convoluted codebase, which can make it difficult to understand and maintain. By reducing cyclomatic complexity, developers can make their code more readable and easier to modify.

Memory usage is another important metric in embedded software development, as the available memory on most embedded systems is limited. By monitoring and optimizing the memory usage of their software, developers can ensure that their software fits within the constraints of the target hardware platform and does not cause performance issues.

Performance metrics, such as execution time and power consumption, are also critical in embedded software development. These metrics can help developers ensure that their software meets the required performance goals and does not consume too much power, which can be a critical concern in battery-powered devices.

In addition to the metrics discussed above, there are many other metrics that can be used to evaluate the quality and performance of embedded software. By regularly measuring and analyzing these metrics, developers can identify potential issues and areas for improvement in their software and ensure that it meets the needs of the target hardware platform and end users.

Overall, software metrics play a critical role in embedded software development by providing a way to quantitatively evaluate the quality, complexity, and performance of software. By regularly monitoring and analyzing these metrics, developers can identify issues and make informed decisions to improve the reliability and efficiency of their software.

![coffee writing computer blogging](https://i0.wp.com/davidloor.com/wp-content/uploads/2022/12/pexels-photo.jpg?resize=800%2C533&ssl=1)

To add the user roles to the body of your WordPress pages, you can use the `body_class` hook. This hook allows you to add custom classes to the `<body>` element of your pages.

## Example of body\_class hook to add classes to the body element

Here’s an example of how you can use this hook to add the user roles to the body of your pages:

```
function add_user_roles_to_body_class( $classes ) {
    $current_user = wp_get_current_user();
    $user_roles = (array) $current_user->roles;
    foreach ( $user_roles as $role ) {
        $classes[] = 'role-' . $role;
    }
    return $classes;
}
add_filter( 'body_class', 'add_user_roles_to_body_class' );

```

This code will get the current user’s roles and add a class to the body for each role. For example, if the user has the “editor” and “author” roles, the body will have the classes `role-editor` and `role-author`.

You can then use these classes in your CSS to style different elements differently based on the user’s role.

**Note:** This code should be placed in your theme’s functions.php file or in a custom plugin.
How to decode a cryptogram using matrices
Published: 2022-12-24 04:28:30

Have you ever encountered a cryptogram and wondered how to decode it? If so, you’re in luck! Today we’re discussing ‘How do you decode a cryptogram using matrices?’ Using matrices to decode a [cryptoquote answer](https://cryptoquoteanswer.xyz) is a simple yet effective method that can help you crack any code. By understanding the basics of matrices and how they work, you can easily decipher any cryptogram. In this blog post, we’ll discuss exactly how to do that.[todays cryptoquote answer](https://cryptoquoteanswer.xyz/todays-cryptoquote-answers/)

What is a cryptogram?
A cryptogram is a type of puzzle where a short phrase or sentence is encrypted by replacing each letter with another letter. The goal is to decode the hidden message, usually a quote or proverb, by rearranging the letters in the cryptogram and substituting them with the correct letters. To do this, one must be familiar with encryption techniques such as substitution ciphers, transposition ciphers, and other codes. 

One method for decoding a cryptogram is to use matrices. Matrices are mathematical objects that can be used to represent data in a compact form. When applied to cryptograms, matrices can be used to determine the most likely letter for each position of the cryptogram. To decode a cryptogram using matrices, you need to: 

1. Divide the cryptogram into a number of rows and columns. 

2. Fill in the matrix with letter frequency counts of the original alphabet. 

3. Solve the linear equations in the matrix to find the most likely solution. 

4. Determine which letters correspond to which columns, then plug these letters into the cryptogram. 

5. Repeat until the cryptogram is solved. 

Using matrices to solve cryptograms is an efficient way to quickly decode messages. With practice, it is possible to become proficient at decoding cryptograms with matrices.
