    Personal Finance Management - Saving

    Hello readers of 2coffee.dev, how have you been lately? Are you doing well? The weather in Hanoi has been unpredictable, causing me to go through a rather severe illness, but luckily it didn't last long, and I have fully recovered my writing ability. Recently, there have been many articles on my personal page related to the question of how to manage personal finances, asking about financial management applications, or even articles sharing financial management applications they have created themselves.

    Migrate Sign in with Apple Account

    A few weeks ago, the app at my company underwent the transfer of app ownership in the Apple Store, which means transferring from one Apple Developer account to another. There are many tasks to complete before the transfer; essentially, you need to follow the steps outlined in their list in order to begin the ownership transfer. One of these tasks is to Migrate Sign in with Apple users to another team. All user accounts created by clicking the "Sign in with Apple" button integrated into the app need to have their data migrated. Apple always emphasizes user privacy, so the app transfer to a different account must also ensure privacy. Some information will change, with the most critical being the apple ID (also known as `sub`) and private email.

    How I Made Money from Blogging with IndieBoosting

    Hello readers of 2coffee.dev, I am caught in an endless loop of work, wanting to do everything but time doesn’t allow. I think over time I am falling into a state of distraction, surely I need to find a way out. How about you? Are you doing well? Do you still visit 2coffee.dev more frequently? The reason I ask is that since the beginning of the year, the traffic seems to have stagnated, making me question whether you are okay?

    OpenNotas like a boss - take notes like a boss

    It has been almost a year since the first introduction of the note-taking application OpenNotas (ON). Time flies so fast, just yesterday I was struggling to post product introductions on Facebook, X, and ProductHunt, and in the blink of an eye, I received an email reminding me to renew my domain 🥲, which is truly painful for my wallet. OpenNotas is my first application product and has received a lot of affection. In return, it has always accompanied me throughout this time. By the way, let me reveal some statistics...

    Hard Drive Investigation

    Hello readers, I sincerely apologize for not writing any new articles in the past week. As I shared in [Threads](https://2coffee.dev/threads), last week I was quite busy with a project at the company, and when I got home, I could only update a little information during the day before going to bed to continue listening to the unfinished book. It is "The Fountainhead" - telling the story of a young architect who was expelled because he... had ideas...

    Discussion on Tech Stack

    MEAN stands for the first four letters in a set of MongoDB, Express, Angular, and Node.js. Similarly, LAMP is made up of Linux, Apache, MySQL, and PHP. Additionally, there are many other acronyms with similar meanings such as JAM Stack, T3 Stack... By now, you surely know that these are the set of technologies that help create a complete website or web application, right? Back in school, I really liked PHP and worked on many projects based on PHP. At that time, I used a Windows computer, so the toolkit I used was...

    Challenge of Going Without Coffee

    In the new year, I wish everyone good health to achieve many things and attain even more brilliant successes. This is also the first article to kick off 2025, so let's not talk about work just yet; instead, let's discuss a topic that I believe many people are interested in. That topic is Coffee. Why? What programmer hasn't used it at least once! There is a very striking saying: "In Vietnam, you can find a coffee shop on every street"...

    Semantic Search Optimization

    RAG (Retrieval-Augmented Generation) is a method that combines information retrieval and text generation to improve the quality and accuracy of the answers generated by language models. The simplest way to understand RAG is to imagine chatting with ChatGPT; it almost answers all the questions you ask because it has been trained on many data sources. This is both an advantage and a disadvantage: the advantage is that it knows everything; the disadvantage is that sometimes it doesn't know specific details, providing vague answers. RAG, on the other hand, limits the amount of knowledge the language models learn, or only learns and answers questions based on a limited dataset we provide. It sounds simple, but the reality is quite complex.

    What Do We Just Have? Membership!

    Hello readers of 2coffee.dev. A week has passed without any new articles. Well, not exactly! Although I haven't written a new article, I've been diligently updating short news snippets for you in the Threads section. Here, I will update the most notable news of the day, or simply share something I find interesting. This means I haven't "abandoned" my readers even for a single day, right? 😅. No new articles because last week was quite busy. Busy with work at the company and also with the blog. As you can see, I just
