Give it a try and see how Puppet can become your own invisible puppet master, pulling the strings towards a more efficient and secure IT environment.
Implementing Skeleton Loading in Angular 12: A Directive Approach Without NPM Dependencies
Tags: angular, ui
Published: 2023-12-27 16:46:48

**Introduction**
In the dynamic world of front-end development, managing user experience during data loading is crucial. As an Angular developer with a year of experience, I recently faced a unique challenge: integrating skeleton loading into an application without relying on external NPM modules. This task was prompted by the difficulties in resolving dependency issues in an older repository. My solution? A custom Angular directive for skeleton loading.

**The Custom Directive Approach**
The custom directive I developed in Angular 12 offers a streamlined way to implement skeleton loading. It's designed to render a skeleton component as a placeholder until the data loads and a specific condition is met. This self-contained approach is efficient and aligns with modern development practices in Angular.

**Code Explanation**
**SkeletonDirective**

![SkeletonDirective](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ebyr88zom6jtuq6v38g8.png)
_The SkeletonDirective is an Angular directive that dynamically renders skeleton components based on certain inputs. It uses ComponentFactoryResolver to create instances of SkelectonRectComponent._

1. **Inputs**: _It accepts several inputs like isLoading, size, width, height, and className to customize the skeleton's appearance._
2. **ngOnChanges**: _This lifecycle hook listens for changes, especially to the isLoading input. When isLoading is true, skeleton rectangles are rendered. Otherwise, the normal content is displayed._

**SkelectonRectComponent**

![SkelectonRectComponent](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/cykt969hbe0hm9nlwj3n.png)

1. **Styles**: _The key aspect of this component is its CSS, which uses a shimmer effect to create a skeleton screen. It employs keyframes and linear gradients to achieve this._
2. **Width and Height**: _The component's width and height can be set via input properties, allowing for flexible layout designs._

**Implementation Steps**
![Implementation Steps](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/c6z28xoxry13ocbqmo4e.png)
 _Use the directive in Angular templates where skeleton loading is required._

**Conclusion**
This custom Angular directive for skeleton loading is a practical solution for enhancing user experience without external dependencies. It demonstrates the power of Angular's directive and component system, offering a flexible and efficient approach to managing UI states during data loading. This method is particularly useful for projects where adding external libraries is not feasible due to compatibility or other constraints.
AWS-Lambda (Start/Stop EC2 Instance)
Tags: linux, devops, aws
Published: 2023-12-27 16:30:45

AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers.

- Lambda functions are efficient whenever you want to create a function that will only contain simple expressions 

- Each Lambda function runs in its own container. When a function is created, Lambda packages it into a new container and then executes that container on a multi-tenant cluster of machines managed by AWS.

Step-1.Create the EC2 Instance.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rh7xncruyxhcheqta1hn.png)
 

Step-2. Create IAM Roles and policies.

- Create a policy > Select EC2 type >Access level -Write (Stop Instance).

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7u3jrifzzvpuxhhyko5k.png)

Engineering Management Tip #4
Published: 2023-12-27 15:47:11

Write a mini doc (or as needed a more formal doc) for:

* ahead of all meetings (including 1:1's)
* projects
* new ideas
* new problems


This allows you to spend your time brainstorming ahead of time and to ask good questions or provide guidance during the meeting. For important meetings set a reminder (e.g., use the Due app) 15 minutes before to ensure the mini doc is written.

Ideally write them in a place where you can share the doc as needed.
履约精神是表象，诚实才是本质
Published: 2023-12-27 15:40:11

**“诚实”是基石，而履约精神等等是更上层的东西；**

---

- 比如评估一个人是否具备极强的履约精神，那么得看这个人是否追求诚实，诚实是否是他的底层价值观？

- 是否具备说话的勇气，是否具备说真话的勇气，是否具备像一个傻子一样说出一些“不合时宜的话”，是否总是保持沉默（冷漠之徒），是否总是喜欢赞许别人（虚伪之徒）；

- 如果你能坦诚的对待一切，那么坦诚的对待合约只是顺便的事情；
诚实高贵在什么地方？
Published: 2023-12-27 15:34:18


- 刚成年前辈们教我做人的道理，学的都是阿谀奉承之术；这样可以给自己带来很大的益处，有利于自己的人生“发展”；

- 故：人际交往啊、说话的艺术啊、沟通的艺术啊...一通学,学的就是人际交往的“智慧”，其实就是虚伪的智慧，阿谀奉承的智慧；

- 然而当我学了更多的东西，看到了更广阔的世界，我发现亲戚们、前辈们教我的“做人的道理”难以解释现在正在运行的世界，也无法解释人类历史的发展规律；

- 我开始发现这个“做人的道理”有问题，“诚实”才是“做人的道理”，真正该坚守的正确方向；这是真理；

- 而为何说“诚实”高贵，就是因为在一个虚伪的社会中，你若“诚实”，便会遭到排斥，敌对；这需要勇气，有可能会让自己短期内失去很多东西；比如在领导面前怎么说话，如何说、说什么？你若张嘴就来，真实的表达自己，会被视为“愚蠢”；

- “诚实”的高贵之处在于：敢于且愿意放弃潜在的利益，甚至明知可能给自己带来不利而为之，此堪称高贵；
In the Software Industry - Do Titles Matter?

People usually are trained for hierarchy and do not tread beyond theirs, when it comes to decisions. The reasoning here is to ascertain safety in daily work. A similar extension applies to the IT industry as well. 

There exists a well-defined structure in most software companies that allows people to expand vertically in their careers. It's generally addressed as climbing up the corporate ladder and flows as follows:

![Engineering Hierarchy](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ydkpo7iiqb6mwac3tj9a.png)

Now I think this is a perfectly valid structure as it allows for clear delegation of roles and responsibilities. It also ensures individuals have ample scope to display the apt team-building and leadership skills at each level as required before moving on to the next one.

But as is the case for a lot of concepts, there exists a counter-point to this one as well. Here, critics often say that a formal structure is a lot of unnecessary bureaucracy, complicates work and encourage flat hierarchies instead. These are wherein one can work anywhere in the above chain but without the "**title**". Additionally they say leadership is not in the title but more so in actions.

I politely disagree with the counter-point. My oft used example: would we people consider, listen eagerly and be influenced by the opinions of executive leaders like Mark Zuckerburg, Sundar Pichai, Elon Musk, Susan Wojcicki, Padmasree Warrior, Mira Murati if they all were anything else?

Most likely a big No.

On the other hand, we would hardly be aware of the entry-level employees in each of the above leaders's companies let alone know and be influenced by their opinion.

However, my post is not to berate anyone but outline how titles matter. They're vital to let people know who are the decision makers in a formal organisational structure but more importantly why they are so. While with great power comes great responsibility but it gives an individual tremendous influence as well.

This leads me to the interesting question as headlined:
