Prometheus and Grafana: A Beginner's Guide
Published: 2024-06-03 21:42:36

## 1. Prometheus Stores Data:

-  Collects and stores time-series data from different sources (exporters).
-  Acts like a data library, organizing and saving metrics over time.
-  Automatically manages storage by removing older data to make space for new.
-  Stores metrics in compressed and optimized format that's easy to query and retrieve.
-  Requires installation of exporters on the systems you want to monitor.

## 2. Grafana:

-  Grafana is a visualization and dashboarding tool that allows you to create interactive and customizable dashboards
-  Grafana integrates seamlessly with Prometheus and other data sources to display time-series data in a user-friendly and informative way.
-  When you set up Grafana, you configure it to connect to your Prometheus instance as a data source.
-  Grafana queries the Prometheus database to retrieve the metrics you want to visualize.
-  Creates custom dashboards to display data in an understandable way. 

## Working Together:

-  Exporters (e.g., , mysqld_exporter) are needed to provide metrics. 
-  Prometheus scrapes metrics from exporters at scheduled intervals.
-  Grafana connects to Prometheus to access and request specific metrics.
-  Grafana translates Prometheus data into dynamic, colorful visualizations.
-  This collaboration allows monitoring and informed decision-making. 

## Conclusion
As you start using Prometheus and Grafana to keep an eye on your apps and make sure they work well, think of these tools as your helpful companions. Don't hesitate to dive deeper, experiment, and explore the vast capabilities they offer.
You should probably have a Bragging Doc
Tags: career
Published: 2024-06-03 21:27:13


Getting a dev job is one thing, but being recognized at that job is another.

Expanding on the advice of advocating for yourself, it’s important that you keep track of your own accomplishments and contributions to the company. I’ve personally been pretty terrible at keeping track of the work that I’ve done and had trouble showing the “impact” that I’ve had on my team. I had the mentality that my work would speak for itself. 

Silly me, that’s incorrect and a terrible way to think 🙂

When performance reviews came around I was scrambling to remember everything I had worked on in the past year and talk up how much I was improving the product. There’s also a social aspect of contribution that’s harder to track down.

Aside from performance reviews, I believe it’s also a good idea to keep a bragging doc handy for when you’re trying to get promoted. At least where I’ve worked, there’s usually some process of collecting proof that you’re performing at the next level. There’s more involvement with your manager, but the idea is similar on your end.

It may sound like a lot of work to maintain, but it’ll save you a lot of cramming and searching once you start. Future you will thank you. Probably 😛

I'm learning something new!
Tags: reactnative, ios, fullstack
Published: 2024-06-03 20:40:50

I've been learning React Native from a tutorial. It's a great tutorial - just slightly fast-paced and a little bit "spoon fed". However I'm getting a feel for what React Native is like. I already know React and have written a bunch of applications in it, so React Native is easy enough. Views and Text instead of divs and h1, p, etc. Also we're using nativewind, which is written on top of tailwind. This is the third time for me using tailwind. I learned frontend first, so I normally code my own CSS. Another benefit is that I didn't have to load xcode onto my laptop. I'm using expo, which is a godsend.

My only complaint is that I'm new at this, so every step of the way I introduce a bug. Sometimes it goes unnoticed, like putting a comma in a list of classNames. With React, or JSX, this will work sometimes and not work other times, so when it stops working it's a mystery. Then I compare my code with the instructor's code or ask ChatGPT. Right now I'm stuck playing a video (using expo-av). I'm going to just go on and see if I can play the stored videos that appear in a second FlatList.

ChatGPT hasn't actually helped much. It keeps telling me to install the expo cli, to make sure I've installed this or that package, etc., which I have. It did catch one bug where I wrapped the callback function in curly braces when it required parentheses. Nothing worked at all until ChatGPT told me of course it wouldn't do anything until I fixed the error. I was grateful.

The this Reference
Tags: java, programming, learning, beginners
Published: 2024-06-03 20:04:00

The keyword **this** refers to the object itself. It can also be used inside a constructor to invoke another constructor of the same class.

The **this** _keyword_ is the name of a reference that an object can use to refer to itself. You can use the **this** keyword to reference the object’s instance members. For example, the following code in (a) uses **this** to reference the object’s **radius** and invokes its **getArea()** method explicitly. The **this** reference is normally omitted, as shown in (b). However, the **this** reference is needed to reference hidden data fields or invoke an overloaded constructor.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ops3ishzmpd6hg4gxrzh.png)

## Using **this** to Reference Hidden Data Fields

The **this** keyword can be used to reference a class’s _hidden data fields_. For example, a datafield name is often used as the parameter name in a setter method for the data field. In this case, the data field is hidden in the setter method. You need to reference the hidden data-field name in the method in order to set a new value to it. A hidden static variable can be accessed simply by using the **ClassName.staticVariable** reference. A hidden instance variable can be accessed by using the keyword **this**, as shown in Figure below (a).

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/83o8lmabatbv6lgdjitq.png)

The **this** keyword gives us a way to reference the object that invokes an instance method. To invoke **f1.setI(10), this.i = i** is executed, which assigns the value of parameter **i** to the data field **i** of this calling object **f1**. The keyword **this** refers to the object that invokes the instance method **setI**, as shown in Figure above (b). The line **F.k = k** means that the value in parameter **k** is assigned to the static data field **k** of the class, which is shared by all the objects of the class.

## Using **this** to Invoke a Constructor

The **this** keyword can be used to invoke another constructor of the same class. For example, you can rewrite the **Circle** class as follows:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zs6bxa2h5e2p2ve75qdb.png)

The line **this(1.0)** in the second constructor invokes the first constructor with a **double** value argument. Java requires that the **this(arg-list)** statement appear first in the constructor before any other executable statements. If a class has multiple constructors, it is better to implement them using **this(arg-list)** as much as possible. In general, a constructor with no or fewer arguments can invoke a constructor with more arguments using **this(arg-list)**. This syntax often simplifies coding and makes the class easier to read and to maintain.

The Scope of Variables
Tags: java, programming, learning, beginners
Published: 2024-06-03 19:52:57

The scope of instance and static variables is the entire class, regardless of where the variables are declared. Local variables are declared and used inside a method locally. 

This section discusses the scope rules of all the variables in the context of a class. Instance and static variables in a class are referred to as the _class’s variables_ or _data fields_. A variable defined inside a method is referred to as a _local variable_. The scope of a class’s variables is the entire class, regardless of where the variables are declared. A class’s variables and methods can appear in any order in the class, as shown in Figure below (a). The exception is when a data field is initialized based on a reference to another data field. In such cases, the other data field must be declared first, as shown in Figure below (b). For consistency, this book declares data fields at the beginning of the class.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/cr3fpekh38ol7mmmr46b.png)

You can declare a class’s variable only once, but you can declare the same variable name in a method many times in different nonnesting blocks.
If a local variable has the same name as a class’s variable, the local variable takes precedence and the class’s variable with the same name is _hidden_. For example, in the following program, **x** is defined both as an instance variable and as a local variable in the method.

```
public class F {
private int x = 0; // Instance variable
private int y = 0;
public F() {
 }
public void p() {
int x = 1; // Local variable
 System.out.println("x = " + x);
 System.out.println("y = " + y);
 }
}
```

What is the output for **f.p()**, where **f** is an instance of **F**? The output for **f.p()** is **1** for **x** and **0** for **y**. Here is why:

- **x** is declared as a data field with the initial value of **0** in the class, but it is also declared in the method **p()** with an initial value of **1**. The latter **x** is referenced in the **System.out.println** statement.
- **y** is declared outside the method **p()**, but **y** is accessible inside the method

To avoid confusion and mistakes, do not use the names of instance or static variables as local variable names, except for method parameters
Immutable Objects and Classes
Tags: java, programming, learning, beginners
Published: 2024-06-03 19:45:17

You can define immutable classes to create immutable objects. The contents of immutable objects cannot be changed. Normally, you create an object and allow its contents to be changed later. However, occasionally it is desirable to create an object whose contents cannot be changed once the object has been created. We call such an object as _immutable object_ and its class as _immutable class_. The **String** class, for example, is immutable. If you deleted the setter method in the
**CircleWithPrivateDataFields** class, the class would be immutable, because radius is private and cannot be changed without a setter method.

If a class is immutable, then all its data fields must be private and it cannot contain public setter methods for any data fields. A class with all private data fields and no mutators is not necessarily immutable. For example, the following **Student** class has all private data fields and no setter methods, but it is not an immutable class.

```
  public class Student {
  private int id;
  private String name;
  private java.util.Date dateCreated;
 
  public Student(int ssn, String newName) {
  id = ssn;
  name = newName;
  dateCreated = new java.util.Date();
 }

 public int getId() {
 return id;
 }

 public String getName() {
 return name;
 }

 public java.util.Date getDateCreated() {
 return dateCreated;
 }
 }
```

As shown in the following code, the data field **dateCreated** is returned using the **getDateCreated()** method. This is a reference to a **Date** object. Through this reference, the content for **dateCreated** can be changed.

`public class Test {
public static void main(String[] args) {
 Student student = new Student(111223333, "John");
java.util.Date dateCreated = student.getDateCreated();
 dateCreated.setTime(200000); // Now dateCreated field is changed!
 }
}`

For a class to be immutable, it must meet the following requirements:

- All data fields must be private.
- There can’t be any mutator methods for data fields.
- No accessor methods can return a reference to a data field that is mutable
How to Install and Configure Cloudflared on Linux

### Step 4: Verify the Installation
Check if `cloudflared` is installed correctly by running:

```sh
cloudflared --version
```

### Optional: Configuring Cloudflared as a Service
To set up `cloudflared` as a system service, follow these steps:

1. **Create a configuration file:**

   Create a directory for the configuration file if it doesn't exist:

   ```sh
   sudo mkdir -p /etc/cloudflared
   ```

   Create a configuration file `/etc/cloudflared/config.yml` with your desired settings. For example:

   ```yml
   tunnel: your-tunnel-id
   credentials-file: /path/to/your/credentials-file.json

   ingress:
     - hostname: example.com
       service: http://localhost:8000
     - service: http_status:404
   ```

2. **Create a systemd Service Unit File:**

   Create a file at `/etc/systemd/system/cloudflared.service` with the following content:

   ```ini
   [Unit]
   Description=cloudflared Tunnel
   After=network.target

   [Service]
   TimeoutStartSec=0
   Type=notify
   ExecStart=/usr/local/bin/cloudflared --config /etc/cloudflared/config.yml run
   Restart=on-failure
   RestartSec=5s

   [Install]
   WantedBy=multi-user.target
   ```

3. **Enable and Start the Service:**

   Enable the service so that it starts on boot:

   ```sh
   sudo systemctl enable cloudflared
   ```

   Start the service:

   ```sh
   sudo systemctl start cloudflared
   ```

4. **Check the Service Status:**

   Verify that the service is running correctly:

   ```sh
   sudo systemctl status cloudflared
   ```

This setup should ensure that `cloudflared` is installed and running on your Linux system.
