Opinion: CS Education Should Include More Code Reading
Tags: learning
Published: 2024-04-12 05:31:18

I was reading through the code for an amazing open source project called [BFBAN](https://github.com/BFBAN/bfban-website) today. Specifically, I was reading the SQL scripts. There I encountered many familiar SQL stuff, but also many SQL stuff that I didn't know: `json` data type, `ENGINE=InnoDB`, `COLLATE=utf8mb4_0900_ai_ci`, `COMMENT`, `PRIMARY KEY (`id`) USING BTREE`...... As I understood these concepts with the help of Copilot and documentation, I developed a better understanding of MySQL and starting thinking this blog's topic.

My (could be arbitrary) point is: I don't think in today's CS education (in some universities at least), students are reading (or instructors are not assisting students to read) enough good quality code for students to produce good quality code. 

If you want to write good articles or essays, you should first read and "digest" quite a few classical books or essays (e.g. Plato's work, Shakespeare's work) to understand word-by-word, sentence-by-sentence, paragraph-to-paragraph how good essays should be written usually with the help from teachers to build up the "vocabularies".  

Then how comes when it comes to CS education (especially the software engineering part), students are expected to know how to program properly after only a few semesters' equivalent of "learning the ABCs" without much exposure and understanding of good quality code? 

Maybe the instructors could do some live coding sessions just like what software developers would do when they pair-program? Maybe the instructors could pick some entry-level but good quality open source code bases to let the students to write "summary and response" with? Maybe instead of asking "who knows answer to this question", instructors could ask a student to the front and present his/her idea to improve existing sample code? Those are just some random thoughts, but maybe we can draw experiences from how writing was taught (or should I say, "should be taught") in school.

I remember listening to this video [Can Great Programmers Be Taught](https://www.youtube.com/watch?v=LtRWu9DErgU&list=PLLxJFnTawO9oMFpcWAfWh8o79Jhhf2AGj&index=6&t=3376s&pp=gAQBiAQB) discussing the software engineer education. I remember that one of the argument the present made was that programming can be taught properly by reducing the class capacity, increasing in-class interaction, essentially "tailoring" the education to the audience, subsequently increasing the cost of education (or should I call it individual tutoring at this point) by a large amount. (Just think about how much you are paying for your CS education, then multiply that by a few times). 

I do agree that the greatest programmers are self-taught, because programming is a field that just isn't possible to be 100% taught, a field where the practitioner must be willing to "chew through the book like a worm" to build up their programming knowledge. But I still think that good introductory CS education will guide beginners towards the right direction and speed up their progress.
Date Range Calendar in Flatpickr Example
Tags: laravel, php, flatpickr, calendar
Published: 2024-04-12 05:30:00

Hello, developers! Today, let's explore how to implement a Date Range Calendar in your web applications using Flatpickr. 

Flatpickr is a lightweight and customizable JavaScript date picker library, and the best part? We're going to keep things simple by using CDN (Content Delivery Network) files.

In this article, I'll give a step-by-step guide for the date range calendar in flatpickr in laravel 8, laravel 9, laravel 10, and PHP.

So, let's see the date range calendar in flatpickr example, flatpickr date range, how to set date range in datepicker, how to set date range in flatpickr, date range picker laravel 8/9/10.

> Step 1: Setting Up Flatpickr


First things first, make sure Flatpickr is included in your project. You can either download it or use the CDN. For simplicity, let's go with the CDN:

```
<!-- Include Flatpickr CSS and JS via CDN -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/flatpickr/dist/flatpickr.min.css">
<script src="https://cdn.jsdelivr.net/npm/flatpickr"></script>
``` 

> Step 2: Create an HTML Input Element

Add an input field to your HTML file with a class that you'll use for initializing Flatpickr:

```
<input type="text" class="date-range-picker" placeholder="Select Date Range">
``` 

Example

Create an HTML file (e.g., index.html) and include the necessary CDN links for Flatpickr:

```
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Date Range Calendar with Flatpickr</title>

    <!-- Flatpickr CSS CDN -->
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/flatpickr@4.6.9/dist/flatpickr.min.css">

    <!-- Flatpickr JS CDN -->
    <script src="https://cdn.jsdelivr.net/npm/flatpickr@4.6.9/dist/flatpickr.min.js"></script>
</head>
<body>

<input type="text" class="date-range-picker" placeholder="Select Date Range">

    <script>
        // Initialize Flatpickr
        flatpickr('.date-range-picker', {
            mode: 'range',
            dateFormat: 'Y-m-d',
        });
    </script>
</body>
</html>
```

Note that disabled dates (by either minDate, maxDate, enable or disable) will not be allowed in selections.

```
{
    mode: "range",
    minDate: "today",
    dateFormat: "Y-m-d",
    disable: [
        function(date) {
            // disable every multiple of 8
            return !(date.getDate() % 8);
        }
    ]
}

```

Preloading range dates

```
{
    mode: "range",
    dateFormat: "Y-m-d",
    defaultDate: ["2024-02-10", "2016-02-20"]
}
```

And there you have it! In just a few simple steps, we've integrated a Date Range Calendar into our web application using Flatpickr with CDN files.

Database Education Needs Moderization
Tags: database, learning
Published: 2024-04-12 04:52:42

I just bombed my database course exam today. I am not gonna blame anyone else. It's was because I didn't properly study how to join multiple tables.

But it made me think during the exam: I really wish I could had the assistance to write SQL code from AI. It is certainly not allowed during exams, but I should had used it when I was learning it. Actually, it should be made available during the learning process. Combined with the fact that this class is taught using MAMP with MySQL version of 5.x.x while the textbook published in 2014 whose SQL examples are mostly of Oracle dialect......, I think the database education really needs some modernization. (Kinda a arbitrary opinion though, considering I haven't researched how other colleges / universities teach database courses.)

Just raising the problem is not enough. I don't want to be just another complainer. I will think about some ways (also existing ways) to modernize database education in my free time. Specifically I want the teaching to:

1. Be in line with latest popular SQL syntax 
2. Have user-friendly way to install tools with AI assistant equipped with knowledge of the database
3. Maybe integrate sample projects and exercises from popular textbooks to "standardize" them all?


[vanna-ai](https://github.com/vanna-ai/vanna) is a pretty cool project that combines AI with database knowledge. [SQLAI](https://www.sqlai.ai/about) seems to be a small German company which specializes in this area. I will start exploring these in my free time.
DynamoDB as API

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/g3b60xdtxx7ch9i5t7cd.jpg)
I developed a Terraform Module "DynamoDB-as-API" which will create a AWS REST-API to Read items from your DynamoDB tables (Create, Update, Delete will be added soon).  You just provide the list of DynamoDB tables, this module will read schema of all tables and will generate endpoints accordingly.

eg. Below code will create an API with GET endpoints for **books** and **authors** for each Partition Key and Sort Key (if any).  Since it read directly from DynamoDB without any Lambda, the response time will be lightning-fast...
```hcl
module "dynamodb-as-api" {
  source  = "CloudPediaAI/dynamodb-as-api/aws"
  version = "1.0.0"

  api_name = "Library-API"
  domain_name = "city-library.com"

  dynamodb_tables = {
    "books" = {
      table_name         = "books-table"
      allowed_operations = "R"
    },
    "authors" = {
      table_name         = "authors-table"
      allowed_operations = "R"
    }
  }
  providers = {
    aws           = aws.provder_for_api
    aws.us-east-1 = aws.provder_for_ssl
  }
}
```

Published: 2024-04-12 04:23:59


[Nerdearla ](https://nerdear.la)conferences are big, free events all about science and technology. They're organized by Nerdearla and have been happening since 2014. At these conferences, you can go in person or join online. You'll find cool stuff like working together, chatting live, listening to talks, attending workshops, and meeting experts in the field.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/h9j5x5j7mcf5090vbjq6.png)

I discovered Nerdearla only this year, and so far, it's been truly interesting to pay attention to. It started on April 11 and will finish on Saturday, the 13th. If you happen to be in Santiago, please share in the comments what you think about it.

On its first day, all conferences were online, and they were fully recorded and published on their YouTube channel at https://www.youtube.com/@nerdearla. This is a good opportunity to catch up on the topics. Most of them are in Spanish, but some in English were really good. I particularly recommend these two from the English speakers at the conference:

This talk delves into the malicious code injected into the Linux Kernel a few weeks ago. The approach is interesting because an expert in security actually demonstrates with code how to exploit this. It's quite creepy indeed.

This session offers more news and opportunities to contribute to Open Tofu, the fork from Terraform. Not long ago, there was a change in license to BSL, leaving a bunch of developers in tears and anger! But hey, we can always have these nice fork projects rise from the ashes!

There were plenty of other conferences and workshops, and what is also important for some developers, some nice work opportunities in the country with a faster channel of communication with some companies and their current job postings. 

I hope you can also enjoy this!
２章８
Published: 2024-04-12 04:07:03

申し訳ありませんが、誤解を招く説明をしてしまいました。

質問のコードを再度確認すると、`var` キーワードを使用していますが、これはJava 10以降であれば型推論を使って適切な型が推論される機能です。この機能により、最初に `B` クラスのインスタンスを作成し、その後で `C` クラスのインスタンスを作成して `a` に代入しています。

ただし、`var` を使用すると、最初に割り当てられた型に基づいて変数の型が推論されます。ですので、`var a = new B();` とした場合、`a` は `B` 型と推論されます。その後に `a = new C();` とすると、`C` のインスタンスを `B` 型の変数に代入しようとしているため、これは型の不一致であり、コンパイルエラーが発生します。

このため、解答としては「コンパイルエラーが発生する」が正しいです。`B` と `C` は共に `A` を継承していますが、互いには関連がないため、`B` 型の変数に `C` 型のインスタンスを代入することはできません。

コードにコメントを追加して説明します。

```java
// test() メソッドを持つ基底クラス
public class A {
    public void test() {
        System.out.println("A");
    }
}

// Aを継承し、test() メソッドをオーバーライドしているBクラス
public class B extends A {
    @Override
    public void test() {
        System.out.println("B");
    }
}

// Aを継承し、test() メソッドをオーバーライドしているCクラス
public class C extends A {
    @Override
    public void test() {
        System.out.println("C");
    }
}

// プログラムを実行するためのmainメソッドを含むMainクラス
public class Main {
    public static void main(String[] args) {
        // 最初にBクラスのインスタンスを作成し、aはB型と推論される
        var a = new B();
        // B型の変数aにCクラスのインスタンスを代入しようとするとコンパイルエラーが発生
        a = new C(); // ここでコンパイルエラー
        // エラーがなければ、aが参照するオブジェクトのtest()メソッドを呼び出す
        a.test();
    }
}
```
