Abstract classes and AOP

I wanted to avoid writing boilerplate code for CRUD in Spring Boot. But I failed - I could not make my child aspect get along with my child controller. Before adopting AOP, I had an abstract controller which the child controller inherited. CRUD worked well and I no longer needed to repeat the code for simple CRUD anymore. I was happy. // MyAbstractController public abstract class MyAbstractController<T extends UniversalModel> { private final .

Super Thinking Chapter 01

Being Wrong Less Inverse thinking. Instead of thinking how you can save money, think about how you can reduce your expenses. Unforced error. A personal shortcoming which can be controlled. Anti-fragile. Treating setbacks as challenges and thriving on them. Keep it simple, stupid! Arguing from first principles. De-risking. Challenging assumptions and verifying or debunking them. Premature optimisation. Minimum viable product. Ockham’s razor. “The simplest explanation is usually the right one.” Conjunction fallacy.

Sticky

I found myself entangled in CSS. I needed app-header to stick to the top at all times. I also needed template-header to be right beneath app-header at all times. Lastly, embedded-content should begin immediately after template-header and should not be sticky. Here’s how the page organisation might look like: <div class="app"> <div class="app-header"> <!-- Content --> </div> <div class="app-content"> <div class="template-container"> <div class="template-header"> <!-- Content --> </div> <div class="embedded-content"> <!-- Content --> </div> </div> </div> </div> The simplest approach is to place app-header and template-header inside a single div.

reCaptcha on-error

Polling wasn’t effective because: Hot reloading did not happen because of some heap limit error. I called the wrong function to check if the reCaptcha errored. To deal with the heap limit, my buddy suggested updating the docker-dev script in package.json to: { "scripts": { "docker-dev": "export NODE_OPTIONS=\"--max-old-space-size=4096\" && ..." } } As for checking if the reCaptcha errored, neither on-expire nor captchaService.isValid worked. A possible explanation for the former would be that the reCaptcha didn’t expire.

Reaping the Benefits

Section 3: “Reaping the Benefits” This section connects better listening and information management to better decision-making and benefits that can span entire organisations. Chapter 12: “Connecting Better Listening to Better Judgment” Learning from others and constantly reconstructing ideas leads to discoveries and insights. Chapter 13: “Changing Your Organisation through Listening” “Foster a more disciplined and productive organisation.” The example raised was the organisation of organisation-wide meetings. In these meetings, speakers need to be well-prepared and adhere to strict requirements.
