Two Weeks into Coding Bootcamp
Tags: webdev, javascript, programming, beginners
Published: 2023-06-18 23:26:15

# Two Weeks In

I've just wrapped up the second week of my coding bootcamp and the excitement hasn't worn off, yet. I'm benefiting greatly from having a live person explaining the concepts along with being able to code with them side by side and ask questions as they pop up. The first week was HTML and CSS fundamentals, which I already had a pretty good grasp on after trying out a few intro courses over the past year. Week two was about more complex CSS concepts, such as Flexbox. I thought I had a fairly good grasp on it until I tried coding some from scratch. I'm going to try reading more documentation before trying again. Other than that, I'm feeling great about the course so far. This week's challenge is to create a portfolio using the HTML and CSS we have learned so far. Creating a portfolio is something I've put off for a while since I think mine would not be advanced enough. I'm glad the course is forcing me to do so, since it will be very important in the job search. Next week, we start JavaScript which is the language that has been the toughest for me to learn. I'm hoping this new way of learning will finally make the language click for me.
Three tips to deal with boring developer job.
Tags: productivity
Published: 2023-06-18 23:08:38

It's your first day join your dream startup company, you feel exited, you wondering what kind of task that you will do, It's your dream come true to be part of startup that change the world and maybe the next chat GPT kind of company.

Fast forward three years later, did you feel as exited as your first day of work? If your answer is solid Yes, congratulation you really lucky to have a dream job, but most of us don't.


You bored with your day to day job, because your sprint project has done and your JIRA task is nothing more than some small changes, micro bugfix or maybe just fixing some typos and changing config files or add some event tracking.

The fact that developer most likely will encounter some low-level task is unavoidable, that why we need to maintain our performance event during those days, here some tips to handle boring job

### Tips 1 

Actually you still able to do some improvement, if you're not writing unit testing when you do your task, do it even tough no one ask you for it, if no one create documentation then do it, it will improve your value as developer and also give you more understanding about your product.

### Tips 2
 
You fill boring because you doing similar type of job over and over again, ask your manager to switch project with higher difficult task or doing something that you never done before, such as working on SEO improvement or create email template.

### Tips 3

If none of those above tips is worked, try to do some small project, ask your manager to do small project for your company that hasn't provided such as HR management tools, attendance log report, snack machine management system, pingpong booking system, etc.


We cannot control our job, our manager, our boss but we can control ourself.
Code Review - Documatic

Honestly, I'm so new to being a part of a forum where I am able to ask so many open ended questions so freely, and find so much information from people just like me :) it feels so good! 

Today I found about a coding source called Documatic. As a beginner coder myself, this was a life-changer for me! It's literally google for your code and can be used with a variety of different programs. I've been playing with it for maybe an hour now, and it's answered every single one of my questions. The best part though is you don't need to be an expert to use it! It's able to answer a variety of question regardless of the level of expertise shown by the user. So glad I found it in here!
Code Smell 217 - Empty Implementation
Tags: webdev, javascript, beginners, programming
Published: 2023-06-18 22:55:24

*You create empty methods instead of failing*

> TL;DR: Don't fill in methods to comply

# Problems

- Fail Fast Principle Violation

# Solutions

1.  Throw an error indicating implementation is not complete

# Context

Creating an empty implementation might seem fine to jump to more interesting problems. 

The code left won't fail fast so debugging it will be a bigger problem

# Sample Code

## Wrong

[Gist Url]: # (https://gist.github.com/mcsee/56e55a0fdee9d223fc050652b298f699)
```javascript
class MerchantProcessor {
  processPayment(amount) {
    // no default implementation
  }
}

class MockMerchantProcessor extends MerchantProcessor {
  processPayment(amount) {
     // Empty implementation to comply with the compiler
     // Won't do anything
  }
}
```

## Right

[Gist Url]: # (https://gist.github.com/mcsee/77dcf4848f489f7011aefbe4971d4b0a)
```javascript
class MerchantProcessor {
  processPayment(amount) {
    throw new Error('Should be overriden');
  }
}

class MockMerchantProcessor extends MerchantProcessor {
  processPayment(amount) {
     throw new Error('Will be implemented when needed');
  }
}

// or better...

class MockMerchantProcessor extends MerchantProcessor {
  processPayment(amount) {
    console.log('Mock payment processed: $${amount}');
  }
}


```

# Detection

[X] Manual

Since empty code is valid sometimes only a good peer review will find these problems.

# Conclusion

Being lazy and deferring certain decisions is acceptable, but it's crucial to be explicit about it.

EventEmitter in JavaScript can cause out of memory
Published: 2023-06-18 20:47:21

How can I avoid memory leaks caused by event listeners and event emissions in my Electron app, specifically when continuously reading data from a connected device through a serial port?

I have developed a desktop app using Electron.js and TypeScript. The purpose of this app is to read real-time data from a device connected to it. The app needs to continuously read both analog and digital data from the device. Initially, when the device is connected and data reading is started by listening to the serial port session, everything works fine. However, after approximately 2 hours of continuous data reading from the serial port session, an error occurs: 

---
**[electron] <--- Last few GCs --->
[electron] 
[electron] [11247:0x3aa8002c0000]  4812376 ms: Scavenge 10.4 (20.9) -> 4.2 (20.9) MB, 0.13 / 0.00 ms  (average mu = 1.000, current mu = 1.000) task; 
[electron] [11247:0x3aa8002c0000]  4812823 ms: Scavenge 10.4 (20.9) -> 4.2 (20.9) MB, 0.13 / 0.00 ms  (average mu = 1.000, current mu = 1.000) task; 
[electron] [11247:0x3aa8002c0000]  4813281 ms: Scavenge 10.4 (20.9) -> 4.2 (20.9) MB, 0.19 / 0.00 ms  (average mu = 1.000, current mu = 1.000) task; 
[electron] 
[electron] 
[electron] <--- JS stacktrace --->
[electron] 
[electron] FATAL ERROR: Cannot grow ExternalPointerTable past its maximum capacity Allocation failed - process out of memory**


After initiating the app to continuously read analog data from the device, it functions smoothly for approximately 2 hours. However, after this period, the app crashes due to insufficient memory, resulting in the exception shown in the following image: Image description 
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/khbzf0lksuupu0cd37bh.png)

so how we can avoid memory leak that occur by event listener and emit the event  as i guess in my case?

Laziness at work: How to harness it without getting fired
Tags: productivity, programming, webdev, discuss
Published: 2023-06-18 20:07:44

In [a previous post](https://dev.to/gajaguar/harnessing-the-power-of-laziness-in-software-development-5ged), I mentioned how being "lazy" could contribute a lot to our work, as well as avoiding unnecessary errors. Sounds great, right?

However, indiscriminate use of laziness can bring more problems than benefits. Lazy operations often make our code harder to understand, debug, and test. Sometimes, you might not even know when or how an expression is evaluated, or what side effects it could have. And if not careful, we could end up with a huge expression that was never evaluated or, even worse, cause a stack overflow.

## With great power comes great responsibility

Some of the considerations we can keep in mind regarding the use of lazy loads or evaluations are:

- Use them only when it makes sense. We shouldn't be lazy just for the sake of it; if an expression is cheap to compute, or its value is needed immediately, simply execute it.
- Be aware of the trade-offs. Can it improve performance and modularity? Yes, but it can also introduce complexity and unpredictability; so we must make sure we understand the benefits and costs of using it in a specific context.
- Test the code thoroughly. It is very likely that it will be more prone to failures and errors, so we must make sure to test it with different inputs and scenarios, and thus verify if there are unexpected behaviors or results.
- Document everything, well... Not everything. Lazy operations can make the code less readable and maintainable; so it's advisable to make sure we clearly document and explain why and how they were used.

---

Developing with a lazy focus is a powerful tool that can help us write better software. But like any tool, it can also be misused or abused. Use laziness carefully and cautiously to make the most of its benefits without falling into its possible pitfalls.

Remember, don't let laziness take over you!

We applied everything we learned in this course!!!
**First** - I created new project on my GitHub
**Second** - I uploaded my project in "computational Biolagy" written with python
In this Project I Researched the Genom of Bacillus subtilis bacterium by math functions
**Third** - writing README file
**Four** - uploading necessary files to run the project such as requirements file 
**Five** -  Added the mentor
When my GitHub area for my project was building I recieved 2 PR from my partner who wrote the project with me - Eliyahou Levy
The first PR was to add [test_main]

Firestore
Published: 2023-06-18 18:32:58


# Firestore rules

- If no rules are applied to a resource, no one can read/write in it.
- Rules are applied to *and only* to the specified matched pattern and are not recursive. For instance allowing read access on `/users/{uid}` won't allow read access on `/users/{uid}/documents/{docId}`.
- Only 1MB of data per document.

### Accept access for everyone

```
match /path/to/resource {
  allow read: if true;
}
```

### Accept access if the user is connected

```
match /path/to/resource {
  allow read: if request.auth != null;
}
```

### Make a resource user-specific

```
match /user/{uid}/path/to/resource {
  allow read: if request.auth.uid == uid;
}
```

### Defining a function
```
function isAllowed(userId) {
  return request.auth.uid == userId;
}
match /user/{userId}/path/to/resource {
  allow read, write: if isAllowed(userId);
}
```

# JavaScript Web Modular SDK

- `addDoc`: takes a collection and add the provided data, a document is appended to the collection with an auto-generated id. 
- `setDoc`: takes a document path (with custom id) and insert data, creates the document if it doesn't exist, if the document already exists the document is replaced (**everything** is replaced by the new data and data might be lost unless `{ merge: true }` is used).
- `updateDoc`: takes an existing document path (with custom id) and merge data, but if the document doesn't exist, the call throws an error.

## onSnapshot

- Can listen both on a document or a collection.
- Callback on a document is called when information in the document changes **but not if a collection is created/updated/removed inside of it** (in fact a collection does not directly belong to a document.)
- Callback on a collection is called when documents are added/updated/removed inside this collection **but not if a collection is created/updated/removed inside one of the documents**

## arrayUnion

- Doesn't work with `setDoc` and will replace all values.
- Should be used with `updateDoc`.
