    CLI Application for Managing Posts

    Hello readers of 2coffee.dev. Another week has passed, so quickly that when looking back at the homepage, I couldn't believe that I had stopped writing for such a long time. To be honest, last week was quite busy as I was focused on releasing an important update for the product at work. Perhaps that's why the concept of time has temporarily been buried. Hmm... Need to think of something to talk about...

    Eating your own dog food - Using your own product

    Many years ago when I first started my internship, I worked at a company specializing in making products and then doing business based on those products. Nowadays, people often call it a Products company. The main product at that time was for business customers. Later, I learned it was the B2B model - that is, selling to business customers. Although I was directly involved in the product development phase, to be honest, many features that I created, I did not understand why they should be made...

    Bring your own coffee everywhere

    Hello readers of 2coffee.dev, the stronger seasonal winds have arrived in the North. If you're going out, remember to wear warm clothes, while I'm feeling a bit feverish, not having adjusted to this weather yet. Yesterday, I returned from my hometown to Hanoi, wearing shorts and a sleeveless shirt in cold drizzle, with just one change of clothes and a water bottle in my backpack. Wait, why did I bring a water bottle? Well, actually, it’s my coffee brewing bottle.

    Semantic Search Feature

    Hi there, 2coffee.dev readers. Have you noticed that the autumn atmosphere has become clearer in Hanoi recently? The morning was cool, and the evening came with strong winds. But behind that was a busy week for me. I was focused on running the "deadline" for my company's project, and in the evening, I tried to complete the search function for my blog. This deadline was different from usual because it was the main feature for the year for the product. And as for the blog, the search function had to be completed sooner or later, and this was the perfect time to do it.

    Practicing Data Processing by Using Commands on the MTTQVN Ledger File

    Recently, the Central Committee of the Vietnam Fatherland Front (MTTQVN) has uploaded 12,028 pages of ledgers of donations to support people affected by storm No. 3. Right after that, many lively discussions around this topic broke out on social media. And quickly, many people created websites to look up the ledger information. Just enter any content in the search box, click the button, wait a moment, and the found data will be displayed on the screen. As we all know...

    Everything is "Free" - Part II - The Data Cake

    Everything is free, then the user is the "product" - a phrase that many people have heard somewhere. Most people are willing to create free products to attract users and then find ways to make money from this user base. This way is very common in the present because it is easy to approach and attract users. While they don't have to pay to use, the data they provide is the premise for other revenue-generating activities, such as advertising...

    Musings on the Morning Running Story

    Before dawn breaks, my heavy footsteps thud against the ground. Hanoi is in the peak of a heat wave, so the weather after 8 AM is no different from a furnace being stoked from the ashes of the previous night. This is also the reason why evening runs after 6 PM have become increasingly sparse because...

    Tear Down and Rebuild

    Hello readers of 2coffee.dev, it's been a while since I last met you. After completing and launching the OpenNotas project in early June, a week later was dedicated to "fixing bugs," and recently I took a short trip to "reset" myself after six months of hard work. By the way, have you all made plans for your next trip? Take some time to rest and enjoy life; don't dive too deep into work or you might get "overloaded"...

    All about OpenNotas - What is it?

    Nearly 2 months ago, while being loyal to Apple Notes for writing, suddenly my iPhone broke down, forcing me to switch to an Android device due to budget constraints. At this point, I realized that Apple Notes could no longer be used on the new device. Imagine before when all notes between the computer and the phone were being synchronized smoothly, but now that process has been interrupted, causing a terribly uncomfortable situation. While struggling...

    Diary of Working on Notas - Ready for Launch!

    These past few days as I've been going to work, under the blazing sun, I suddenly caught sight of a bright purple light. Oh, it turns out to be the purple crape myrtle, which has been blooming for who knows how long, signaling another summer is approaching. I recall the day when I boldly declared to make a note-taking app for this reason and that reason, it was still a bit chilly then, but in a blink of an eye, we're about to step into the extreme heat of early summer. It's been 2 weeks already...
