Dart is a programming language developed by Google. It is designed for building web, mobile, and server applications. Dart is known for its focus on simplicity, productivity, and performance. Dart can connect to various types of databases through different libraries and packages. The choice of database depends on the specific requirements of your project.

The problem is, mostly guidelines that available in Youtube or websites explain about connecting database inside frameworks like Flutter or Aqueduct. It’s common to use the database solutions that are well-supported and integrated with those frameworks but you need also a high hardware resource. I still can’t find a website explain about how to connect Dart outside the framework.

So, I will explain in this article about it. I assume that you’ve already familiar with MySQL dan Dart. I use Dart SDK version: 3.1.5 (stable) (Tue Oct 24 04:57:17 2023 +0000) on “windows_x64” and mysql Ver 15.1 Distrib 10.4.28-MariaDB, for Win64 (AMD64), source revision c8f2e9a5c0ac5905f28b050b7df5a9ffd914b7e7.

I’m sure you are questioning why I wrote the code in Windows instead of Linux. Actually, dart and Xampp can run both in Windows and Linux. And the moment, I’m in the middle of working with Visual Code in Windows, so why not.

Step 1. Create a new user, make a database and table in MySQL.
When I use ‘root’ user that has no password, it didn’t work. So I create a new user because I don’t want to change the default configuration in MySQL. You can create your own database.

Step 2.Download the MySQL library in Dart.
Open file pubspec.yaml, add

dependencies:
   mysql1: ^0.19.0

On the terminal, type:

c:\> dart pub get
Resolving dependencies... (1.1s)
  js 0.6.7 (0.7.0 available)
  lints 2.1.1 (3.0.0 available)
  mysql1 0.19.2 (0.20.0 available)
  web_socket_channel 2.4.0 (2.4.1 available)
Got dependencies!
c:\>

Step 3. Write the dart code.

import 'package:mysql1/mysql1.dart';

Future createConnection() async {
  final MySqlConnection connection = await MySqlConnection.connect(ConnectionSettings(
    host: 'localhost',
    port: 3306,
    user: 'testing',
    db: 'contact',
    password:'testing'
  ));
  return connection;
}

Future fetchData() async {
  final MySqlConnection connection = await createConnection();
  Results results = await connection.query('SELECT * FROM person');
  
  for (var row in results) {
    print('${row['id']}'
    '${row['name']}'    
    '${row['mobile']}'
    '${row['category']}'
    '${row['city']}');  
  }
}

void main() {
    fetchData();
}

Run and the output will be:

C:\bin> dart run .\temp.dart
1Michael Angelo0812-12341234FriendJakarta

3Andri0815-33334444vseafoodBogor
4Mike0815-33334444vfoodBogor    
C:\bin>

You can modify the output to make it more nice to see.

import 'package:mysql1/mysql1.dart';

Future createConnection() async {
  final MySqlConnection connection = await MySqlConnection.connect(ConnectionSettings(
    host: 'localhost',
    port: 3306,
    user: 'testing',
    db: 'contact',
    password:'testing'
  ));

  return connection;
}

Future fetchData() async {
  final MySqlConnection connection = await createConnection();
  Results results = await connection.query('SELECT * FROM person');

    Lrec_city=row['city'].toString().length;    //hitung panjang data city

    print('${row['id']}${' '*(Lid-Lrec_id+1)}' //kurangi panjang field dgn panjang data

  }
  print(baris*70);
  await connection.close();
  //----------------------------------------------------------

Visualizing trigonometric graphs using Python can be done with the help of various libraries, such as Matplotlib and NumPy. These libraries provide powerful tools for numerical operations and creating high-quality plots. In this introduction, I’ll walk you through the basic steps to visualize trigonometric functions using Matplotlib.

import matplotlib.pyplot as plt
import numpy as np
from math import radians
x=np.arange(0,360,1)
y1=np.sin(np.radians(x))
y2=np.cos(np.radians(x))
plt.title('Trigonometric Graphics')
plt.grid()
plt.xlabel('x')
plt.ylabel('y')
plt.plot(x,y1,label='y=sin(x)')
plt.plot(x,y2,label='y=cos(x)')
plt.legend()
plt.show()

Builing an IT infrastructure is an important process for supporting company efficiency. It has to be a well-planned system. If it works optimally the company can reduce costs and even help increase the productivity of the business.

However, the standard procedure may vary depending on the specific requirements, size of the building, and the complexity of the network.
Below are the general outline of the steps.

1.Need Assessment
This is the most important step. You have to know the client’s need. You have to determine the networks requirements and objectives for the building. How many users that will use the system, types of devices, bandwidth requirements, coverage areas dan future scalability because the company may have plans for expansion.

There are few criteria must be fulfilled when you setup an IT Infrastructure.

2.Network design
The next step is network design. You have to plan the placement of networking equipment, such as routers, switches, and wireless access points. There are few consider factors:
-limited space on the corner, you may have to use a mounted rack that provide access to devices both from the front and rear, cabling requirements, network segmentation
and location of the server rooms.

1.Zero Latency
Latency can be interpreted as the time needed to move data from one place to another. Each device can have different latency depending on the level of network quality it has. Inappropriate router or switches can cause latency.
2.Zero Downtime
Any downtime will interfere with the company’s operational activities.That’s why proper installation and infrastructure are very important.
3.Capacity storage
Storage system that can deliver superior performance.
4.Virtualization
Virtualization has benefits as follows:
-energy saving (no hardware)
-faster server provision (deployment is faster)
-improved disaster recovery (replication can be done easily)
5.Security
Security is one of the most important in having the ideal IT infrastructure. The main role of security system is to remove any vulnerable and put the system into optimized status.

3.Cabling Infrastructure
You have to make sure that you follow the industry standards for cable instalation and labeling. Well organized cabling will make your life easier for future troubleshooting. UTP cable maximum range is 100m, if the server location is far, Fiber-optic cable is a good solution.

4.Network Equipment Installation
Installation and configure the network equipments. Using Mikrotik or Cisco will make easier to remote the device. I give example for these 2 brands because I only familiar with it.

5.Network Configuration
Setting IP address, subnet masks, routing protocols, VLAN’s, security, DHCP (Dynami Host Configuration Protocol) servers, Firewall rules and network monitoring tools.

6.Wireless Network Configuration
Optimize the location to ensure reliable coverage and minimize interference. Use appropriate SSIDs (SErvice Set Identifiers) and latest security setting (WPA2/WPA3 Encryption).

7.Testing and Troubleshooting
In this step, you have to verify cable integrity, measure signal strength, and test network throughput. You have to ensure proper connectivity, data transmission, and performance.

8.Security Implementation
Configure access controls, user authentication, and network segmentation as needed. Implement security measures such as firewalls, intrusion detection systems, and encryption protocols to protect the network from unauthorized access and potential threats.

9.Documentation and Labeling
Network cabling infrastructure is the backbone of any network, connecting devices, servers, switches, routers, etc. Without proper documentation and lebeling, network cabling can become a mess. Proper documentation and labeling will save your time and help you maintain consistency and standards across your network, ensuring compatibility and performance.

10.Network monitoring and maintenance
Set up network monitoring tools to monitor the network performance, security incidents, and potential faults. Regular update firmware or security patches for network devices. Regular inspection for all equipments. Periodic cable testing.

Jupyter Notebook is part of Project Jupyter which is announced by Fernando Pérez in 2014. It’s a spin-off project from IPython and become the kernel for Jupyter.
Jupyter is a language agnostic and support other programming language like Python, Julia, R, Haskel and Ruby. It’s 100% open-source.
The file format for Jupyter is ‘.ipynb’.
The Jupyter kernel is responsible for handling various type of request (code execution, code completion, inspection) and providing a reply. Since it can connect to many kernels,
it can provide programming in different languages.

In this tutorial, I use:
-Xubuntu 18.04
-Docker 20.10.14

I’ve downloaded Jupyter/datascience-notebook before, that’s why there are 2 now. Docker will not replace the image although the image name is the same. The images are differentiated with Image ID.

STEP4. RUNNING THE IMAGE

The image is ready. Now, we can run it to create the docker container.
If you don’t specify the container name, docker will create it for you.
$ docker run -p 8888:8888 jupyter/datascience-notebook
If you specify the name, you will get the container as you specified.
$ docker run -p 8888:8888 –name=jupyter-notebook jupyter/datascience-notebook

darklinux@darklinuxpc:~$ docker run -p 8888:8888 --name=jupyter-notebook jupyter/datascience-notebook

        file:///home/jovyan/.local/share/jupyter/runtime/jpserver-7-open.html
    Or copy and paste one of these URLs:
        http://2557ebac7ab1:8888/lab?token=de96fd0d44694ef387ae34c27a4222d1976dbdb795aaa308

STEP5. RUNNING FROM CONTAINER
Open other linux terminal and check the docker IP address.
In my device is: 172.17.0.1

darklinux@darklinuxpc:~$ ifconfig docker0
docker0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 172.17.255.255

darklinux@darklinuxpc:~$

Use this IP address and Jupyter port, to open Jupyter_notebook in browser.
So, it become: 172.17.0.1:8888

Use the token for the password.
de96fd0d44694ef387ae34c27a4222d1976dbdb795aaa308

STEP6. CHANGE THE PASSWORD

You can login with the Token, but I prefer login via password.
So,you have to set the password first.
Scrool down the webpage, copy paste the Token in Token text box and Enter a new password.

If you everthing run well, you will the screen below:

Jupyter Notebook is ready to use.

Getting Market Stock Data from Yahoo Finance is not difficult with Python Module – Pandas.
To follow this tutorial at least you know how to run python code.
In this tutorial, I use:
-Python 3.6.9 (default, Dec 8 2021, 21:08:43)
-Matplotlib-3.3.4
-Pandas 1.1.5
-Xubuntu 18.04
and Vim for text editor

Before you start, make sure you are connected to the Internet.

If you don’t have Python, Matplotlib and Pandas, you can install it from Linux Terminal with commands below:

$ sudo apt-get install python3
$ pip3 install matplotlib
$ pip3 install pandas

The source codes:

import datetime as dt
import matplotlib.pyplot as plt
import pandas as pd
import pandas_datareader.data as web

start=dt.datetime(2010,1,1)
end=dt.datetime(2022,4,22)

df1 = web.DataReader('MSFT','yahoo',start,end)
df2 = web.DataReader('AAPL','yahoo',start,end)

plt.plot(df1.Close)
plt.plot(df2.Close)

plt.legend(['MSFT','APPL'])
plt.grid()
plt.xlabel('Year')
plt.ylabel('Price (USD)')
plt.title('STOCK PRICE COMPARISON MICROFSOFT AND APPLE \n JAN 2010 - APR 2022')
plt.show()

You can run it in Linux Terminal, Python IDLE, Jupiter notebook or any Python environtment.

Lanjut ke bagian berikutnya, gaes. Seperti yang sudah dipaparkan pada tulisan sebelumnya, yang akan kita bahas dalam tulisan ini yaitu menjelaskan tentang bagaimana melakukan proses penyimpanan data, langkah-langkah apa saja yang harus dilakukan supaya hasil akhir berkas .csv dapat diimpor dengan baik oleh SLiMS.

Setelah kita paham kenapa berkas .csv yang dibuat, tidak dapat diimpor dengan baik oleh SLiMS, langkah selanjutnya adalah kembali ke aplikasi LibreOffice, di mana dalam tulisan sebelumnya digunakan untuk membuat berkas .csv.

Proses perbaikan berkas dilakukan ketika proses Save As.
