What is with this Hello World? A lot of people are probably wondering why a fresh WordPress install always comes with the familiar Hello World! post. For the non-techies, non-programmers ...
Part 2 – Accessing a Resource Recap This is a continuation of the previous post that I made some time last month. You can start reading from there to get more context – https://www.joseyamut.xyz/2021/02/24/spring-oauth2-using-password-grant-type-with-additional-headers The first part dealt with getting the access token from a 3rd party token service provider using a password grant. The...
Part 1 – Getting the Access Token In this example, I am using the older Spring Security library which is: spring-security-oauth2 The JAR file can be found at Maven public repositories here. Dependency For my case, I am specifically using the release version below because I am trying to match some limitations (Such as what...
…and I am officially loving it! I think I might have found my next Linux distro. NO. I have found my next Linux distro. The Ubuntu 16.04 Xenial Xerus on my personal laptop is getting way too old for comfort. LTS (Long Term Support) it may be, but I think it will be EOL by...
Properties written in YAML format in my opinion reads better, far better for a human, especially when an application has tons of properties in there. Well, after all YAML was designed to be a human-readable data-serialization language. Officially it complies with JSON and is a subset of the latter (depends which version though as I’ve...
In a previous post I wrote about how NetworkManager on Ubuntu 16.04 LTS (Xenial Xerus) lacked some options that are needed to support newer versions of OpenVPN, particularly on versions 2.4 and 2.5. This meant that one would not be able to create a connection configuration to an OpenVPN server using those unsupported options through...
Not that long ago, I wrote about creating my own VPN (Virtual Private Network) for personal use with OpenVPN. In that post I also recounted how I used it for work purposes back when I was still in Singapore. That was several years ago. That time I had no issues connecting to the VPN server...
Now I have always thought about getting a VPN subscription for some time. Already researched a bit about it several times before. I always somehow keep on having second thoughts about getting one for several reasons that I won’t mention here. I’ve already implemented a VPN back when I was still in Singapore, using OpenVPN....
This is an old-ish Star Wars series. I might have seen some episodes across different seasons, but I know I missed a lot. Then it was probably random viewings, never a commitment to watch this great animated series from beginning to end. Now I’m going to. So where to start but in Season 1 of...
My Android Nokia 6.1 Plus will be 2 years old come December (2020). This Nokia has served me well since then. Didn’t really plan on getting this one at all. It was kind of a spur-of-the-moment purchase decision when my 2 other Android smartphones – a Samsung Galaxy Note 1st gen and a Google LG...
One of those people who is guilty of frequently relying on online 3rd party JSON formatting tools so messily formatted JSON strings or one-liners can be saner to read. If you are like me who deal with JSON almost every day for development, reading log messages, error tracing, etc., readability for JSON is a must....
How many countless times must I have found myself with a piece of JSON string that is formatted in a way that makes it very hard for me to read. Perhaps you’ve also experienced this several times too? As a back-end developer, having to deal with a lot of JSON is unavoidable. Heck, I deal...
Mochi is now 7 months old today. I brought her home perhaps when she was around 2 and 1/2 months. At that time lock-down measures because of COVID19 were already being eased. I thought then that it would be a good time to bring home a pup. Staying at home by myself for 3 months...
The other day I was trying to assign a container of, let’s say, numbers distributed across 20 groups, to a container with a smaller size that can only hold up to 6 groups. The bigger group has values from 0 to 19. It also means that group 0 will always have zero number value, 1...
The other day, I was working on a huge JSON object that had a number of collections in it. The entire object had to be saved into a relational database, which means I was mapping out the raw JSON data to its logical representation as database tables. Though the object wasn’t that complicated, it did...
Using Repository implementation with Spring Data, one can develop applications with an underlying database rapidly in Spring Boot. The Spring Data JPA handles the abstraction of the persistence layer quite well. Many times you probably won’t need anything else beyond what it has to offer. A lot can already be done with the exposed methods...
