vector code not compiling
Tags: programming, coding
Published: 2023-06-19 15:49:32

I have this vector project that I made from some sites that contain example code using vectors. None of these
examples compile. Then, out of the blue, I got a header file that opened up with one line of code high lighted!
I have no idea how the DevC++ IDE opened this header file for the vector include library. One line was highlighted! It mentioned that I had to use a compiler parameter:  "-std=C++1". So I went into compiler options and put this line in the C++ compiler parameters. Voila, now everything is compiling and the code example works as expected!!! So why didn't the original compiler work with vectors? I have no idea why that header file showed up? If I hadn't gotten lucky with that vector header file showing up, how would I have even solved the problem?

Taking The Scenic Route With Python Test Automation
Tags: python, beginners, testing, automation
Published: 2023-06-19 15:23:17

One of the largest software ecosystems in the world today is the Python ecosystem. Python code and tools are used by professional software developers, data scientists, academic researchers, software testers, and professionals needing a flexible scripting language. There is a lot to learn in the Python world. 

One area that I think Python excels at is test automation, which is the area of software development that looks at testing pieces of code in various ways for both exploration and validation. You may want to validate that piece of code like class or function does what you think it does, or you may want to explore software by seeing what it can do (or not). There are plenty of tools and approaches to software testing, and while software testing is usually associated with professional software development, it's also an excellent introduction to how to use Python overall, from how to install libraries right up to write and execute Python programs. 

Learning a new skill or approach can be daunting, so sometimes we need a light introduction to a topic to help us ease in. That's why I wrote [Python Test Automation: The Scenic Route](https://leanpub.com/pythontestautomationthelongway). 

This is not a comprehensive "how-to" book or reference but instead an approachable introduction to the topic based on my experience of over 10 years working in software development as a test automation specialist. It's free to download or you can pay the suggested price. Either way, sometimes it's nice to take the scenic route.

Optimizing The Efficiency of Vacuum Processing - Visibility Map
Tags: apachea, postgressql, apache
Published: 2023-06-19 14:23:33

The concept of a visibility map is a feature introduced in PostgreSQL to optimize the efficiency of vacuum processing. It tracks the visibility information of individual data pages within a table.

The main purpose of the visibility map is to reduce the need for scanning entire tables during the vacuum process. When vacuuming a table, one of the primary tasks is to identify and remove dead tuples (rows) from the table's data pages. However, scanning every page of a table can be a time-consuming and resource-intensive operation, especially for large tables. The visibility map addresses this challenge by storing a bit for each data page in a separate map file. This bit represents the visibility status of the tuples on the corresponding data page. It can have two states: "All Visible" or "Some Tuples May Be Invisible."

During vacuum processing, instead of scanning every data page, PostgreSQL first checks the visibility map to determine if a particular page has all visible tuples. If the visibility map indicates that all tuples on a page are visible to all transactions, PostgreSQL can skip the scanning of that page altogether. This optimization significantly reduces the amount of I/O and processing required during vacuuming.

## Freeze Processing

Freeze processing in PostgreSQL offers two modes, known as lazy mode and eager mode, which are chosen based on specific conditions.

By default, freeze processing operates in lazy mode, where it scans only the pages containing dead tuples using the visibility map (VM) of the target tables. On the other hand, eager mode is triggered under certain circumstances. In eager mode, freeze processing scans all pages, regardless of whether they contain dead tuples or not. 

## Improving Freeze Processing in Eager Mode

Earlier versions of the eager mode in PostgreSQL were inefficient as they would scan all pages, even if all the tuples within a page were already frozen.

To address this inefficiency, improvements were made to the visibility map (VM) and freeze process in later versions. The enhanced VM now includes information about whether all tuples within a page are frozen or not. Consequently, when freeze processing is executed in eager mode, pages that solely consist of frozen tuples can be skipped, resulting in improved efficiency.

Feedback. One of the most powerful but least used Gifts. Yes, feedback is a gift. We probably won’t even share feedback if we don’t care about it. Once feedback is given, we expect the opposite person to accept and improve on it kindly. After all, I, as the almighty, all-knowing person, always know it better than the opposite, right? If that is the illusion, we are not providing feedback but boosting our Ego. But, let’s say our intention in our feedback is genuine and comes from a caring point of view. Is it easy to accept and work it out? It depends on the stage you’re to receive. We are often our worst enemies when receiving feedback from Denying, defending, and explaining to the point where we probably even give up. Unless we take feedback as an opportunity to grow, we might handle it like a hot potato and stumble away. While understanding and reflecting, we grow. It can be painful and exciting, but it’s worth every moment since we realise we are transforming. Meaningful feedback can be the difference between a flailing and thriving team. To create a feedback culture in your organisation, constructive feedback is necessary. Transformation is indeed the muscle we reflex. Let’s reflect on every feedback until all is set in stone. It helps our well-being and sets a team culture for others to follow.

How can a backend developer contribute to a seamless user experience?
Tags: backend, userexerprience, systemdesign
Published: 2023-06-19 14:00:00

As a backend developer, it's easy to get lost behind multiple layers of the modern tech stack and focus solely on reading and writing data through the plumbing of software systems. However, it's important to recognize the impact we can have in contributing positively to the user experience. Our goal should not be limited to building functional apps, but to build apps with exceptional user experience that eliminate any kind of toil.

Here are some ways backend developers can help build great user experiences:

🔹 **Understand the user journey:** Get involved from the early stages of the project to gain a full picture of the problem you're solving. As backend developers, we often dive into UML diagrams or architectural patterns, but flipping our approach can be beneficial. Try designing for the best possible user interactions first and then make the necessary technical tradeoffs to achieve them. Placing the user at the heart of architecture design ensures a user-centric approach.

🔹 **Performance tradeoffs:** Performance is crucial for a seamless user experience. Users expect fast and responsive applications. However, it's not always just about speed. Users are willing to wait an extra second if the app delivers value. Understanding when and where to optimize matters a lot. For instance, leveraging techniques like cursor pagination can reduce the load on database servers. Cursors act as pointers to data in the database, allowing relevant records to be selected without fetching all previous records, which can significantly improve performance. However, it's important to balance performance gains with other user-friendly features like the ability to jump to a specific page.

🔹 **Strive for better developer experience:** Enhancing the developer experience may not seem intuitive, but it directly impacts the user experience. By removing toil from the development process, such as having a great CI/CD setup or an excellent local environment, we free ourselves to focus on crucial aspects of the app. Imagine dealing with a flaky development environment daily—our creativity would drain before we even start thinking about the user experience. Tools and processes that enable toil-free development allow us to iterate faster and respond to user feedback effectively.

**> Let's remember that as backend developers, we have the power to shape the user experience. By understanding the user journey, making performance tradeoffs wisely, and prioritizing a seamless developer experience, we can contribute to building exceptional apps that delight users and stand out in today's competitive landscape.**
Button types

I’ve been banging the drum for a [`button type="share"`](https://github.com/adactio/share-button-type/blob/gh-pages/explainer.md) for a while now.

I’ve also written about [other potential button types](https://adactio.com/journal/18903). The pattern I noticed was that, if a JavaScript API first requires a user interaction—like the [Web Share API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Share_API)—then that’s a good hint that a declarative option would be useful:

> The [Fullscreen API](https://developer.mozilla.org/en-US/docs/Web/API/Fullscreen_API) has the same restriction. You can’t make the browser go fullscreen unless you’re responding to user gesture, like a click. So why not have button type=”fullscreen” in HTML to encapsulate that? And again, the fallback in non-supporting browsers is predictable—it behaves like a regular button—so this is trivial to polyfill.

There’s another “smell” that points to some potential button types: what functionality do browsers provide in their interfa es?

Some browsers provide a print button. So how about `button type="print"`? The functionality is currently doable with `button onclick="window.print()"` so this would be a nicer, more declarative way of doing something that’s already possible.

It’s the same with back buttons, forward buttons, and refresh buttons. The functionality is available through a browser interface, and it’s also scriptable, so why not have a declarative equivalent?

How about bookmarking?

And remember, the browser interface isn’t always visible: progressive web apps that launch with minimal browser UI need to provide this functionality.

[Šime Vidas was wondering about `button type="copy”`](https://mastodon.social/@simevidas/110429807794864669) for copying to clipboard. Again, it’s something that’s currently scriptable and requires a user gesture. It’s a little more complex than the other actions because there needs to be some way of providing the text to be copied, but it’s definitely a valid use case.

- `button type="share"`
- `button type="fullscreen"`
- `button type="print"`
- `button type="bookmark"`
- `button type="back"`
- `button type="forward"`
- `button type="refresh"`
- `button type="copy"`

Any more?
