## Effortlessly Exporting and Importing Podman Volumes Across Hosts

Hey folks, let's tackle a common hiccup in managing Podman volumes remotely. If you've tried using `podman volume export` with a remote Podman client, you've likely noticed it's not directly supported. But, I've crafted a workaround that simplifies the process.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/f2yygppv2xavzo9e7hld.png)

### The Challenge

Working remotely and need to move a Podman volume from one server to another? You'll quickly find that `podman volume export` isn't designed for remote client operations.

### The Workaround

The solution lies in two Bash scripts that utilize SSH, SCP, and Podman's capabilities to facilitate volume export and import across remote hosts.

### Exporting Volumes Made Simple

The `podman_remote_volume_export.sh` script connects to your remote host via SSH, exports the specified Podman volume to a tarball, and then SCPs this tarball back to your local machine. It's a straightforward way to get your volume data where you need it.

### Importing as easy

The `podman_remote_volume_import.sh` script then takes over, uploading the exported tarball to a different remote host. It checks for existing volumes (offering an option to overwrite) and imports the volume data efficiently.

### A Few Considerations

- **Safety Checks**: To prevent accidental data loss, there's a prompt for confirmation before overwriting existing volumes during the import process.
- **Clean as We Go**: Both scripts clean up after themselves, removing temporary tarballs to keep your hosts tidy.

### Usage

To run these scripts:
```bash
./podman_remote_volume_export.sh user@remotehost volume_name
./podman_remote_volume_import.sh user@remotehost new_volume_name /path/to/archive.tar
```

### The Bottom Line

The `podman volume export` limitation for remote operations can be circumvented with these scripts, streamlining the process of migrating volumes. Designed for developers familiar with container management, they offer a practical solution to a common problem.

### CODE

For a closer look and potential customization, the scripts are available on Gist: [Podman Volume Management Scripts Gist](https://gist.github.com/XReyRobert/aaec1a69eb38f54d869c6b5447babb20).

Happy containerizing!

Edit 02/19/24:
Just added podman_remote_volume_migrate.sh to do one or multiple volumes in one shot...

```bash
podman_remote_volume_migrate.sh
Usage: /Volumes/UsersData_Macos/Users/xav/scripts/podman_remote_volume_migrate.sh <SOURCE_HOST> <DESTINATION_HOST> <VOLUME_NAME>...

## Weekly Challenge 256

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-256/), [My solutions](https://github.com/manwar/perlweeklychallenge-club/tree/master/challenge-256/sgreen)

## Task 1: Maximum Pairs

### Task

You are given an array of distinct words, `@words`.

Write a script to find the maximum pairs in the given array. The words `$words[i]` and `$words[j]` can be a pair one is reverse of the other

### My solution

For this task, I have a loop that takes the last value from the `words` array and store it in the `word` variable. I then  see if its reverse is in the `words` array, and increment the count if it is. I continue this until the original array is exhausted.

```python
def count_pairs(words: list) -> int:
    count = 0

    while words:
        word = words.pop()

        if word[::-1] in words:
            count += 1

    return count
```

### Examples

```bash
$ ./ch-1.py ab de ed bc
1

$ ./ch-1.py aa ba cd ed
0

$ ./ch-1.py uv qp st vu mn pq
2
```

## Task 2: Merge Strings

### Task

You are given two strings, `$str1` and `$str2`.

Write a script to merge the given strings by adding in alternative order starting with the first string. If a string is longer than the other then append the remaining at the end.

### My solution

My solution will take any number of strings, be it one, two (as per the task) or more. Thankfully Python has the [zip_longest](https://docs.python.org/3/library/itertools.html#itertools.zip_longest) function from itertools to make the task a one-liner.

```python
def merge_strings(words: list) -> str:
    return ''.join(''.join(s) for s in zip_longest(*words, fillvalue=''))
```

The `zip_longest` function returns a iterable of tuples (with an empty string if one list is exhausted). The inner join turns this into a list of strings. The outer join turns this into a string.

The Perl solution follows a similar logic, and uses the [mesh](https://metacpan.org/pod/List::Util#mesh) function from List::Util. The first lines converts an array of strings into an array of single characters. The `mesh` function returns a flat array, so only a single join statement is required.

```perl
sub main (@words) {
    my @arrays = map { [ split // ] } @words;
    say join( '', mesh(@arrays) );
}
```

### Examples

```bash
$ ./ch-2.py abcd 1234
a1b2c3d4

$ ./ch-2.py abc 12345
a1b2c345

$ ./ch-2.py abcde 123
a1b2c3de
```
The Evaluation of Artificial Intelligence (AI)
Published: 2024-02-18 10:54:41


we're sure you've heard a lot about artificial intelligence (AI) and how it's transforming various industries and domains. But how do we know if AI is delivering on its promises and potential? How do we measure the performance, impact, and value of AI systems and applications?

That's where AI evaluation comes in. [AI evaluation](https://dotpotit.com/) is the process of assessing the quality, effectiveness, and ethics of AI solutions using various methods and metrics. AI evaluation can help us understand the strengths and limitations of AI, identify areas for improvement, and ensure that AI is aligned with our goals and values.

AI evaluation is not a one-size-fits-all approach. Depending on the context and purpose of AI, different evaluation criteria and techniques may be applied. 

AI evaluation is important not only for developers and researchers but also for users and consumers of AI. By being aware of the evaluation methods and results of AI, we can make informed and responsible choices about using and trusting AI. We can also provide feedback and suggestions to improve the quality and ethics of AI.
Buy Google Ads Accounts

Published: 2024-02-18 10:44:50

 Buy Google Ads Accounts
Do you want to grow your business online? If you do, then it is essential to establish an advertising account. If you create a Google account, then the search engine begins to gather data and conduct tests which will help you in understanding the audience and advertisements.

It is essential to ensure you get a quality, well-verified account and good prices which will help you save money and time.But if you want then you should get verified Google Ads accounts as it gives you a quick start in getting the best results. SMMProducts does offer you the best quality Google Ads accounts.

What is the benefit of buying Google ads accounts?
Buying Google Ads accounts can have several advantages for businesses wishing to use Google’s advertising network. These well-established accounts have a track record of good engagement and performance data, which can provide marketers with a competitive edge. The main advantages are as follows:

1.     Improved Account Trustworthiness
A history of successful ad campaigns and a solid track record are frequently included with purchased Google Ads accounts. This might increase trust in Google’s advertising platform, resulting in better ad positioning, fewer ad limitations, and perhaps even lower click-through rates.

2.     Skip Learning Phases
To improve ad effectiveness, the platform often goes through learning phases with new Google Ads accounts. Advertisers can skip these first learning periods and launch successful advertisements right away by purchasing pre-existing accounts.

3.     Access to Restricted Features
For new customers, some advanced ad capabilities might not be available. Advertisers who have purchased accounts get immediate access to these tools, including ad extensions and unique audience targeting, which improves the success of the entire campaign.

4.     Higher Spending Limits
Higher spending caps for established accounts may enable advertisers to launch bigger, more effective campaigns without gradually increasing their budgets.

5.     Leveraging Niche Audiences
Older accounts might have cultivated niche audiences over time, which can be useful for advertising aiming to reach particular industries or demographics.

This strategy should be carefully considered, though, as it is against Google’s terms of service to buy and sell Google Ads accounts and doing so could result in account suspension. Instead, for sustained, long-term success, advertisers should concentrate on organically growing their accounts and adhering to Google’s rules.

The best software engineers write instead of code
Tags: beginners, discuss, learning, documentation
Published: 2024-02-18 09:30:07

There is this misconception that software engineering comprises of several people getting together and writing code to meet an end goal but that is not what it is about. You will never see a car manufacturer building a car without some kind of plan, they have an entire dedicated team to the research and development of their next car.

Software engineering is the same process, whenever I try to develop something. I first close my IDE and do not even think of the code as the code is merely an implementation detail. In my document, I write what approaches I want to take when doing something or what it is that I am trying to achieve and from there, I start to flesh out the smaller implementation details of the project.

I would much rather write out the possible unit test cases as this is more important than the code itself. The code can be ugly, and it can be messy but as long as the unit tests pass and we have accounted for all the edge cases that we can identify upfront then I am happy with whatever is needed to achieve the desired goal.

You will often find that important decisions get lost if they are not tracked properly. This can lead to a lack of accountability in the team and unintentional forms of gaslighting where people cannot remember that they agreed to something and when you raise it as a concern then it becomes a problem or it does not get taken seriously.

I try my best now to ensure that any decision that is made by the team is tracked and acknowledged in writing before moving on to the next step, this will save you in the long run.

**What is software Testing?**
Software Testing is a process of ensuring the designed product is free of bugs which is designed for the intended usage.
Software Testing is carried out on a piece of code block or a program or for a build.
Software testing is normally carried out while designing a product.
Testing is carried out to find the known bugs and the software is free from errors.
Testing can be done simultaneously when a product is designed called unit testing by the developer.
After or during the product is designed testing will be carried out by the tester.
**Requirements of Software Testing:**
First the requirement for software testing is analysed and documented.
Software testing has Black box testing, white box testing and grey box testing.
Black box testing can also be called as functional testing.
White box testing is implemented during the coding phase by the developer. 
White box testing is used to find whether the software is designed as per the requirement.
Grey box testing is a combination of black box and white box testing
**Relevance of Software Testing**
Software Testing is used to validate and verify whether the designed software performs the expected and the accepted tasks.
Software testing is performed inorder to confirm the software is working properly.
Software testing is performed inorder to prevent the developed product from failing.
If a product confirms the quality standards then it is accepted that the product will perform flawlessly.
Software Testing not only used while developing new products but also during a change in the code or the module of the product.
Software Testing can be classified as smoke testing, sanitary testing, regression testing, performance testing, user acceptance testing and unit testing.
Exploring the Wonderful World of Large Language Models

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/yg1gljb5hvyad6q9y6g4.png)
Large language models are a type of artificial intelligence technology that can process and generate human language. This means they can read articles, write, translate, and even engage in conversations. One of the reasons I'm interested in large language models is their versatility. Whether it's writing essays, solving problems, or creating stories, large language models can be incredibly useful.

Another aspect that excites me is the learning process of large language models. They are trained on vast amounts of text data, allowing them to understand the structure and semantics of language. This means they can learn from past experiences and continuously improve their performance. I find this concept of "intelligence" fascinating!

In addition, large language models can be used for various interesting applications. For example, they can help us with writing, learning new knowledge, and even creating music and art. I've heard of people using large language models to design game levels and write movie scripts, which is truly amazing!

While large language models have endless potential, they also face some challenges. For example, how do we ensure the content they generate is accurate? How do we address potential ethical issues? These are questions that require serious consideration.

As an enthusiast, I hope to continue exploring the wonderful world of large language models and see how they can change our lives and work. If you're also interested in large language models, please follow along with me as we learn together.
