## TL;DR

Add `(tags (org:your-github-username))` to your `dune-project` file's `package` stanza.

## About

OCAML's opam package manager has an unfortunately little-known feature calling 'tagging'. This allows you to give 'tags' or 'labels' to your packages and search using those tags. This works a lot like popular blogging platforms, like dev.to in fact! And even better, the OCaml.org website package search can already search for tags: https://ocaml.org/packages/search?q=tag:%22org:erratique%22

That's an example of searching for the `org:erratique` tag, which will find all packages by [Daniel Bünzli](https://erratique.ch/contact.en), who meticulously tags his OCaml packages. In fact the `org:` prefix for tags is specifically reserved for the 'organization' (or person) who publishes the package: https://opam.ocaml.org/doc/Manual.html#opamfield-tags

## How to tag

If you are using the [dune](https://dune.build/) build system, add the tag(s) to your `dune-project` file's `package` stanza. E.g.:

```dune-project

(package
 (name dream-html)
 (synopsis "HTML generator eDSL for Dream")
 (description
  "Write HTML directly in your OCaml source files with editor support.")
 (documentation "https://yawaramin.github.io/dream-html/")
 (tags (org:yawaramin))
 (depends
  (dream
   (>= 1.0.0~alpha3))))
```

Of course, you can add multiple tags, e.g. `(tags (tag1 tag2 tag3))`. Refer to https://dune.readthedocs.io/en/stable/dune-files.html#field-package-tags for the documentation.

Make sure you run `dune build` so that dune regenerates the package's `opam` file. Now, commit these changes and the next time you [publish your package](https://ocaml.org/docs/publishing-packages-w-dune) on opam, these tags will appear and be searchable, e.g. https://ocaml.org/packages/search?q=tag:%22org:your-github-username%22

## Namespacing

You might have realized that I am specifically recommending adding the `org:` tag with high priority, because it enables an ad-hoc form of namespacing. The opam registry doesn't auto-enforce namespacing, of course, but you can always appeal to the registry maintainers if you think someone is squatting on your namespace.

## Searchability

Of course, namespacing is not the only benefit–you also improve the searchability of the opam registry by adding this metadata to your projects. For example, if people are looking for web-related projects, they might search for `tag:"web"` etc. This will benefit the entire OCaml ecosystem. And even better, it's really easy to do.

👨‍💻 Daily Code 48 | Random Number 1-100, 🐍 Python and 🟨 JavaScript (3)
Tags: beginners, daily, javascript
Published: 2024-01-24 11:17:53

alright as promised yesterday I’m going to try making the Random Number Generator HTML again today without looking up anything or using any ChatGPT. I already solved that for Python yesterday, so now it’s just JS left

# My Code

Tadaa! Turns out this time I was able to solve it fully on my own!

```html
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>1-100 Random Generator Button</title>
</head>

<body>
    <button id="js-random-button">Generate Random Number</button>
    <div id="js-random-number"></div>

    <script>
        document.getElementById('js-random-button').onclick = function () {
            let randomNumber = Math.floor(Math.random() * 100) + 1;
            document.getElementById('js-random-number').textContent = randomNumber;
        }
    </script>
</body>

</html>
```

Next I want to get more reps with page manipulation. 

I want to become so familiar with this that I can control website content with JavaScript without even thinking much, so I’ll add more exercises to achieve this in the coming days.
What Mr. Robot Teaches Us About Bugs
Tags: programming
Published: 2024-01-24 12:04:41

Sometimes, we act as if bugs just appear in our code by themselves, but we all know that's not true. The errors in my code were written by me. I didn't mean to write them. I didn't want to write them. But I did anyway.

I remember when I first read Al Shalloway referring to a bug as 'code that he had written' and it struck me, I am the author of the bugs in my code. There was no one else to blame but myself.

Many teams accumulate bugs. Instead of listening to the message the bugs are telling us and fixing them as soon as they are found, they identify, track them, and tell themselves that one day they will get rid of them.

Good luck.

That number just grows and grows until there are so many bugs that it becomes unfeasible to fix, so we learn to live with most of them and the bugs drag the project down.

Bugs are often just the tip of the iceberg, they are the harbinger of something much worse to come, a warning sign that things are going wrong. We should pay attention to these warnings and not ignore them.

Some bugs hide very well, and finding them can often be the hardest part of getting rid of them. An old friend tells me that finding a bug in a large system is like being told there is a wrong word in a dictionary. Fixing a wrong word is easy, finding the wrong word can be time-consuming and tedious.

In the series Mr. Robot, in the episode 1.2_d3bug.mkv, Elliot says: 'Debugging isn't just about finding the bug. It's about understanding why the bug was there in the first place. Knowing that its existence was not accidental.'

I have been dealing with bugs for many years as a developer, but only recently started to see them for what they really are: flaws in my software development process.

And like insects, software bugs need the right conditions to breed. Bugs don't just happen, we let them happen.

But it doesn't have to be like this. Instead of accumulating bugs, we can recognize them for the messengers they are and heed their message to get back on track. Every bug is a missing test, a critical distinction we failed to realize. If we can see that, we can not only fix that bug but also prevent a whole series of bugs.

If we can see a bug for what it really is, then it becomes my teacher and we become its grateful students.
Why Flutter BLoC is Loved and Popular by the Developers?
Tags: flutter, dart, bloc, statemanagement
Published: 2024-01-24 12:09:27

- 𝗦𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗖𝗼𝗻𝗰𝗲𝗿𝗻𝘀: Flutter BLoC allows for the separation of business logic and UI. This means that developers can focus on implementing the business logic in the BLoC without worrying about the UI, and vice versa.

- 𝗖𝗼𝗱𝗲 𝗥𝗲𝘂𝘀𝗮𝗯𝗶𝗹𝗶𝘁𝘆: With Flutter BLoC, developers can create reusable business logic components that can be used across different parts of the application. This reduces code duplication and makes it easier to maintain the application’s codebase.

- 𝗣𝗿𝗲𝗱𝗶𝗰𝘁𝗮𝗯𝗹𝗲 𝗦𝘁𝗮𝘁𝗲 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁: Flutter BLoC provides a predictable way of managing the state of the application. The BLoC emits new states in response to events from the UI, making it easier to reason about the application’s behavior.

- 𝗧𝗲𝘀𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆: Flutter BLoC makes it easier to write unit tests for the business logic of the application. Since the BLoC is separate from the UI, it can be tested independently of the UI.

- 𝗟𝗮𝗿𝗴𝗲 𝗮𝗻𝗱 𝗖𝗼𝗺𝗽𝗹𝗲𝘅 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀: Flutter BLoC is particularly well-suited for large and complex applications, as it provides a scalable architecture that can be extended as the application grows.

I built a task management and to-do list app for your goals
Tags: productivity
Published: 2024-01-26 04:00:25

I built a task management and to-do list app that helps you prioritize your tasks toward your goals. 

It helps me focus on what matters and make conscious decision in my daily tasks. I hope it’s useful to you too. It’s currently in V1. I will add more features and integrations in the coming weeks.

You might want to give it a try and share your feedback. Link of my site: https://goalfocus.io/ 

It currently has the following features:

- create SMART goals and break them down into smaller goals and tasks. Then, work on each task progressively toward your main goals

- increase your focus with a timer. You can customize duration for each tasks. Focus on one task at a time

- prioritize tasks with the Eisenhower Matrix based on importance and urgency. Focus on what truly matters while eliminating less important tasks

- motivated by a daily motivational quote that aligns with your current goal

- overcome procrastination with timeboxing. Tobi (CEO of Shopify) [uses timeboxing to overcome Parkinson's Law](https://twitter.com/tobi/status/1615553994759278592). I personally find timeboxing an effective approach too. I added a few features that work well together to help you complete your tasks in a timely manner such as timeframe, due date, due date reminder, and task duration

- weekly, monthly, and yearly reviews help you review progress, course-correct plans, stay motivated, and focus on your next steps for success
