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 ...
Love to read books. When I was still in Primary and Secondary I must’ve read every one of the Hardy Boys and Nancy Drew series that the school libraries had on its shelves. Later I would go on to read titles from big authors like Tom Clancy, Michael Crichton, John Grisham, and Dan Brown to...
…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...
For the last 3 days I have been messing around with Google ChromeOS on a HP Notebook – 15–ay190nia on loan to me for a week. It has been fun so far. Though it’s not all smiles and giggles all the way as it should be, since the hardware on this old thing kind of limits me,...
Something I encounter every now and then on application deployments. This is common especially on the first time you commit/push your code to your Git repository with CI/CD configured. Might have labeled or titled this article wrongly. The error does not happen when the app container is being created on OpenShift. It does not even...
Well, I installed Viber for the Linux desktop today. Yet again. I remember installing it not so long ago only to end up uninstalling it straight away because the application window looked disproportionately huge on my Ubuntu 16.04. The issue is still present now. Describing it, below are a few of what I noticed when...
So I wrote a review about this place – Avida CityFlex Towers @ Bonifacio Global City – on Google Maps that people would know what I thought about it, my experiences, and how I truly felt. It was a mixed feeling overall. I did not feel happy or sad about that place in the end....
Ever since I started reading books, learning about and seeing pictures of places from all around the world, and watching these sites on TV/video or the Internet, I have always had this burning desire to travel there myself, to set foot on these lands and witness it with my own eyes. As of this very...
Tired of using your valid email accounts for registration in various web sites? Maybe it’s just a message board you want to read one time only and from which you don’t want to be saddled with a lifetime of spam. The convention is just to sign up for Gmail, Yahoo Mail, or other free web...
It Stutters Yes, it does. Badly. The lag is very noticeable and happens a lot of times. I cannot even just turn a blind eye on it and pretend there is no stutter. Because it does. Granted there are moments where everything goes smoothly. Not buttery smooth still. Yet, when I’ve gone on a string...
Say I have these numbers in an array, for example: I want to do something with that set of numbers, such as taking out null values, and extracting only the odd ones. Too take it further, maybe I want an even number or two mixed in the processed list as well. So I have this...
Did a simple, customized SQL query builder that’s only specific for UPDATE statements some time early last year. Thought I’d just write it down here. It was a smaller part of a bigger application. It wasn’t required for all update cases, but a number of them did. I’ve mostly re-written it from memory. It should...
I recently started on the path on building content on the fly that gets sent out as soon as possible, using a template engine, but from a back-end perspective. If that makes sense? This is for an event-driven application that sits there and listens for incoming messages. A simple one. Consume the message as soon...
From time to time I get some of this odd API response from requesting information for a specific something. I expect the response data to be a simple JSON object. Instead I am looking at a JSON array. I suppose that is still simple enough and it’s not so odd. This kind of response happens...
Somebody asked me recently why their POJO validator was not working as expected. They had already followed the “code I wrote” down to a T. Emphasis on the quotes, because trust me that block of code for bean validation they used as reference from an older project I did, was pretty much a very trivial...
Yes, this is not a post about a puppy or any living, furry, four-legged companions that many people love and keep at home. Unfortunately. Rather… This is about Diablo III non-combat pets that were intentionally and unintentionally acquired during the course of playing wasting thousands of hours on this once classic and popular, hack and...
For some time now I’ve been planning on learning ReactJS. It is all what front-end developer talk about theses days. Heck, full stack application developer job offers always pair ReactJS with [back end programming language goes here] in the job description almost without fail. That learning plan has not happened yet, though, and unfortunately for...
There is this Java library that I utilize to quickly get values from JSON objects that is fairly easy to use. This would be Jayway JsonPath. More can be had at their GitHub page. It is still being actively maintained. There appear to be a number of contributors involved in this project at different points...
My appetite for media consumption has gone up several notches during the whole pandemic WFH (work from home) phase that has been happening for a long time since March of 2020. Video content to be more exact. All the more so when there was an ongoing lock-down/quarantine/curfew and pretty much all that one can do...
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...
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...
