ULM Diagramming Tool : draw.io

Diagramming is one of the frequent task I am ask to do as a Technical Architect of the 3rd largest Fintech company in the world. Designing a software requires creating loads of UML diagrams to show different processes of the system. Diagrams like component, sequence, class and deployment topology are some of the common diagrams that you will find in software design and implementation documents. These diagrams help the developers and implementor quickly understand the end to end system processes.

Based on my experience, when someone ask you some technical things like interaction between systems, explaining them with diagrams tend to help them quickly grasp what you really wanted to convey.

I used different diagramming tool like MSVisio which is easy to use but a bit expensive. I have one installed in my laptop but was removed when our office IS pushed the Windows update to my laptop. I don't know why, perhaps due to the license cost. I tried different free UML diagramming tools like umlet and ArgUML but they are difficult to use and I don't like the UI interface.
Luckily, I found a good one. It is called draw.io. This diagramming tool is amazing. It is web based (no need to download and install stuff) and fast. I can create different diagrams and save them to OneDrive, Google Drive or download to my laptop. It support PNG format too.

You have an option to save the diagram in Google Drive, OneDrive or local device. File save is in HTML format.

You can reload the diagram from Google Drive.

Basic sample diagram. You can save to a cloud drive or local drive. Diagram can be exported as png, jpeg, etc.

Using search function to look for a diagram.

Here are the diagrams that you can use.

Microsoft Office365

Let's be honest about it. Apple office document apps sucks. Although, I am using Macbook 12-inch model as my personal laptop, I hate their office apps not because they are buggy or not user-friendly; but because of their limited adoption. Few people are using it (none of my friends and colleague uses it). I cannot use it in my work because people will curse me. There is only one instance where I used it, i.e. during our hackaton event. That's it. As expected, like any office worker; I am a regular user of Microsoft Office, i.e. word, powerpoint and excel. I bought office365 since it is cheaper and you always get the latest version. I am using it for 2 years now and my license will end August of this year (August 08, 2018 to be exact). I bought my last 2 licenses from lazada.com.ph for less than 2,000 pesos. As I don't want to lose my access to onedrive.com and office apps; I bought a new 1 year license from lazada.com.ph for 1,499 pesos inclusive of the shippi...

Earthwood Guitar String

My daughter requested a guitar because she wants to learn playing the instrument. We went to SM North to and buy the guitar at JB music store for 900+ pesos. She picked the gray-ish color. It is a beginner's guitar and with the price, I would say, the quality is average. But you can buy the same quality guitar at RJ music store at slightly lower price. One thing that she doesn't like is the strings which is painful to the fingers since they are very 'hard' (not sure if that is the right term though). So I checked Amazon to get some 'soft' guitar strings. Luckily, I found Earthwood that has a good reviews. I ordered and ship the item through my-shoppingbox.com. After almost 15 days, I received the strings. I replaced the old strings and tuned them using an Android App. It really made a big difference playing with Earthwood strings. It is more forgiving to the fingers and has a better sound quality (I am not a musician - just an opinion). My daughter is n...
