#### eBPF a base do Cilium
O eBPF é umas das tecnologias mais faladas nos últimos tempos na comunidade de tecnologia,
isso graças sua capacidade de estender as funções do kernel sem precisar alterar código do kernel ou carregar modulos. Com eBPF você escreve programas em C ou Rust que são compilados em bytecode.
[Guia Ilustrado do eBPF](https://isovalent.com/books/children-guide-to-ebpf/)
#### Afinal, o que é Cilium?
Cilium é um software de código aberto que aproveita das funcionalidades do eBPF para entregar ao kubernetes soluções para Ingress, gateways api, service mesh, segurança e observabilidade entre outras. Ele consegue atuar de forma transparente sem uso de container sidecar como Envoy.
[Documentação Cilium](https://docs.cilium.io/en/stable/overview/intro/#what-is-cilium)
*"eBPF é uma tecnologia de kernel revolucionária que permite aos desenvolvedores escrever
código que pode ser carregado no kernel dinamicamente, mudando a maneira como o kernel
se comporta.
Isso permite uma nova geração de redes de alto desempenho, observabilidade e
ferramentas de segurança. E como você verá, se quiser instrumentar um aplicativo com essas ferramentas baseadas em eBPF, você não precisa modificar ou reconfigurar o aplicativo de qualquer forma, graças ao ponto de vista do eBPF dentro do kernel."
Liz Rice, no seu livro gratuíto [Learning eBPF](https://isovalent.com/books/learning-ebpf/)*
A isovalent também contem vários [labs gratuitos](https://isovalent.com/labs/) para aprender usar o Cilium e outras ferramentas da Isovalent, como o hubble, e ainda você ganha badges do Creddly 😍.
#### Compilando um novo Kernel para o WSL ###
Para conseguir carregar os módulos necessários vamos precisar compilar um kernel já com as funcionalidades necessárias ativas, o WSL padrão vem com o kernel 5.15, mas já que vamos precisar recompilar tudo, vamos colocar logo um mais novo, vamos baixar o kernel 6.8, que é a versão padrão do Ubuntu 24.04, também alguma features do Cilium somente estão disponíveis em versões mais novas do kernel como pode ver na tabela abaixo.
**Meu ambiente**
**Sistema operacional:** Windows 11 23H2
**Distro WSL**: Ubuntu 24.04 LTS
**Versão do WSL:** 2.1.5.0
**Docker Desktop**: 4.30
**Gerenciador de pacotes:** Scoop
|Cilium Feature|Minimum Kernel Version|
|---|---|
|[Bandwidth Manager](https://docs.cilium.io/en/stable/network/kubernetes/bandwidth-manager/#bandwidth-manager)|>= 5.1|
|[Egress Gateway](https://docs.cilium.io/en/stable/network/egress-gateway/#egress-gateway)|>= 5.2|
|VXLAN Tunnel Endpoint (VTEP) Integration|>= 5.2|
|[WireGuard Transparent Encryption](https://docs.cilium.io/en/stable/security/network/encryption-wireguard/#encryption-wg)|>= 5.6|
|Full support for [Session Affinity](https://docs.cilium.io/en/stable/network/kubernetes/kubeproxy-free/#session-affinity)|>= 5.7|
|BPF-based proxy redirection|>= 5.7|
|Socket-level LB bypass in pod netns|>= 5.7|
|L3 devices|>= 5.8|
|BPF-based host routing|>= 5.10|
|IPv6 BIG TCP support|>= 5.19|
|IPv4 BIG TCP support|>= 6.3|
Abra o shell do Ubuntu WSL, no seu gerenciador de terminal, o meu é o [Windows Terminal](https://github.com/microsoft/terminal),
e siga os passos
1. Instale as ferramentas necessárias para compilação
```bash
sudo apt update && sudo apt install build-essential flex bison libssl-dev libelf-dev bc python3 pahole
```
2. Baixe o kernel no repositório do linux, baixando só a branch que vamos usar no casol linux-6.8.y.
```bash
## baixando do repositorio
git clone --depth 1 --branch linux-6.8.y https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
### Entre na pasta
cd linux
```
3. Estando dentro da pasta, linux, vamos baixar o arquivo de configuração padrão do kernel do Wsl e salva-lo como .config.
```bash
wget https://raw.githubusercontent.com/microsoft/WSL2-Linux-Kernel/linux-msft-wsl-6.1.y/arch/x86/configs/config-wsl -O .config
```
4. Vamos fazer o replace das entrada LOCALVERVSION para generic
```
sed -i 's/microsoft-standard-WSL2/generic/' ./.config
```
5. Vamos ajustar o arquivo .config para atender a todos os requisitos do Cilium
- Vamos criar um arquivo chamado *cilium_modules* e colocar o conteudo abaixo dentro.
```bash
## linux/cilium_modules
## Base requirements
CONFIG_BPF=y
CONFIG_BPF_SYSCALL=y
CONFIG_NET_CLS_BPF=y
CONFIG_BPF_JIT=y
CONFIG_NET_CLS_ACT=y
CONFIG_NET_SCH_INGRESS=y
CONFIG_CRYPTO_SHA1=y
CONFIG_CRYPTO_USER_API_HASH=y
CONFIG_CGROUPS=y
CONFIG_CGROUP_BPF=y
## Iptables-based Masquerading
CONFIG_NETFILTER_XT_SET=m
CONFIG_IP_SET=m
CONFIG_IP_SET_HASH_IP=m
## L7 and FQDN Policies
CONFIG_NETFILTER_XT_TARGET_TPROXY=m
CONFIG_NETFILTER_XT_TARGET_CT=m
CONFIG_NETFILTER_XT_MATCH_MARK=m
CONFIG_NETFILTER_XT_MATCH_SOCKET=m
## IPsec
CONFIG_XFRM=y
CONFIG_XFRM_OFFLOAD=y
CONFIG_XFRM_STATISTICS=y
CONFIG_XFRM_ALGO=m
CONFIG_XFRM_USER=m
CONFIG_INET_ESP=m
CONFIG_INET_IPCOMP=m
CONFIG_INET_XFRM_TUNNEL=m
CONFIG_INET_TUNNEL=m
CONFIG_INET6_ESP=m
CONFIG_INET6_IPCOMP=m
CONFIG_INET6_XFRM_TUNNEL=m
CONFIG_INET6_TUNNEL=m
CONFIG_INET_XFRM_MODE_TUNNEL=m
CONFIG_CRYPTO_AEAD=m
CONFIG_CRYPTO_AEAD2=m
CONFIG_CRYPTO_GCM=m
CONFIG_CRYPTO_SEQIV=m
CONFIG_CRYPTO_CBC=m
CONFIG_CRYPTO_HMAC=m
CONFIG_CRYPTO_SHA256=m
CONFIG_CRYPTO_AES=m
```
- Agora, vamos criar um script Python chamado **enable_conf.py** , para obter o conteúdo arquivo cilium_modules e ajustar o .config.
```python
import re
# Lê o conteúdo do arquivo 'cilium_modules
config_replacements = {}
with open('cilium_modules', 'r', encoding='utf-8') as file1:
for line in file1:
line = line.strip()
# Ignora linhas vazias e comentários
if not line or line.startswith('##'):
continue
key, value = line.split('=')
config_replacements[key] = value
# Lê o conteúdo do arquivo '.config'
with open('.config', 'r') as file2:
file2_lines = file2.readlines()
# Mantém um conjunto para controle das chaves que foram atualizadas
updated_keys = set()
# Substitui linhas correspondentes em '.config'
with open('.config', 'w', encoding='utf-8') as file2:
for line in file2_lines:
# Verifica se a linha contém alguma chave de 'cilium_modules' usando regex
for key, value in config_replacements.items():
if re.search(r'\b' + re.escape(key) + r'\b', line):
# Se a linha estiver comentada, remove o símbolo de comentário e atualiza
if line.startswith('# ' + key):
line = f"{key}={value}\n"
# Atualiza o valor da linha
elif re.search(r'^\s*' + re.escape(key) + r'\b', line):
line = f"{key}={value}\n"
updated_keys.add(key)
break
file2.write(line)
# Adiciona as chaves que não foram encontradas ao '.config'
for key, value in config_replacements.items():
if key not in updated_keys:
file2.write(f"{key}={value}\n")
```
[Gist](https://gist.github.com/cslemes/36ffb29194724cf266d69779b8b5f2f2)
- Execute o script
```
python3 enable_conf.py
```
6. Agora só rodar o Make, pode deixar todas perguntas no padrão.
```bash
make -j $(nproc)
```
7. Finalizando a compilação, instale os moduloes.
```bash
sudo make modules_install
```
8. Vamos criar uma pasta no Windows, para colocar o kernel novo, lembrando que todas as do WSL compartilham o mesmo kernel, então vamos colocar no drive C:.
- No Ubuntu crie o diretório.
```bash
mkdir /mnt/c/wslkernel
```
- Copie o novo kernel para a pasta vamos renomear para **kernelcilium**
```bash
cp arch/x86/boot/bzImage /mnt/c/wslkernel/kernelcilium
```
9. Agora vamos alterar o .wslconfig para as distros subirem com o kernel novo,
pode usar o seu editor de texto de preferencia, estando no windows, navegue até a pasta, $env:USERPROFILE e edite o .wslconfig, e adicione a configuração conforme abaixo.
```
[wsl2]
kernel = C:\\wslkernel\\kernelnoble
```
10. Feche as janelas abertas com o wsl e derrube todas as distros.
```
wsl --shutdown
```
11. Abra o Ubuntu novamente e confirme se está usando o kernel novo.
```
uname -r
```
12. Vamos criar o arquivo de configuração para os modulos necessários carregarem na inicialização.
```bash
awk '(NR>1) { print $2 }' /usr/lib/modules/$(uname -r)/modules.alias | sudo tee /etc/modules-load.d/cilium.conf
```
13. Vamos reiniciar o daemon e o serviço de modulos
```bash
sudo systemctl daemon-reload
sudo systemctl restart systemd-modules-load
```
12. Checando se está tudo certo
```bash
$cris /kind ❱❱ sudo systemctl status systemd-modules-load
● systemd-modules-load.service - Load Kernel Modules

#### Criando o Cluster kubernetes com Kind
Instalando o client Cilium, você pode fazer todas a instalação também usando Helm.
A partir de agora usaremos somente o powershell para criação dos recursos, primeiramente vamos criar um cluster usando o Kind.
1. Crie o arquivo de configuração do kind, vamos desativar a rede padrão e o kubeproxy.
```yaml
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
extraPortMappings:
# localhost.run proxy
- containerPort: 32042
hostPort: 32042
# Hubble relay
- containerPort: 31234
hostPort: 31234
# Hubble UI
- containerPort: 31235
hostPort: 31235
- role: worker
- role: worker
networking:
disableDefaultCNI: true
kubeProxyMode: "none"
```
2. Agora vamos instalar o Cilium no cluster para isso vamos usar o cliente do cilium, a instalação também pode ser feita via helm.
- Baixe a ultima release do [Cilium](https://github.com/cilium/cilium-cli/releases) para sua plataforma, e descompacte em uma pasta de sua preferencia, lembrando que para executar em qualquer prompt precisa colocar o local do executavel na varivel de ambiente PATH.
```powershell
## Baixando
aria2c https://github.com/cilium/cilium-cli/releases/download/v0.16.10/cilium-windows-amd64.zip
## descompactando
unzip.exe .\cilium-windows-amd64.zip
```
- A opção que prefiro é usar o Scoop, o Cilium não está em nenhum bucket official, então vamos precisar criar uma instalação customizada.
- Crie uma arquivo chamado cilium.json e coloque o conteúdo abaixo.
```json
{
"bin": "cilium.exe",
"version": "v0.16.10",
"url": https://github.com/cilium/ciliumcli/releases/download/v0.16.10/cilium-windows-amd64.zip"
}
```
- Agora é somente instalar com o scoop apontando para o arquivo json.
```powershell
scoop install cilium.json
```
3. Agora é só executar o comando do cilium para instalar ele no cluster ele vai achar seu cluster pelo contexto atual do .kube/config, pode confirmar usando o comando `kubectl config get-contexts` ,
```
cilium install
```
```powershell
$cris /kind ❱❱ cilium install
🔮 Auto-detected Kubernetes kind: kind
✨ Running "kind" validation checks
✅ Detected kind version "0.23.0"
ℹ️ Using Cilium version 1.15.5
🔮 Auto-detected cluster name: kind-kind
ℹ️ Detecting real Kubernetes API server addr and port on Kind
🔮 Auto-detected kube-proxy has not been installed
ℹ️ Cilium will fully replace all functionalities of kube-proxy
```
Depois de alguns minutos o Cilium está pronto, podemos verificar os status do cilium com o cli.
```powerhell
cris /kind ❱❱ cilium status
/¯¯\
/¯¯\__/¯¯\ Cilium: OK
\__/¯¯\__/ Operator: OK
/¯¯\__/¯¯\ Envoy DaemonSet: disabled (using embedded mode)

```
Caso exiba algum erro, você pode dar uma olhada no status do daemont set, e conferir os logs dos pods.
```powershell
$cris /kind ❱❱ k get daemonsets -n kube-system
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal SuccessfulCreate 6m47s daemonset-controller Created pod: cilium-c74rc
Normal SuccessfulCreate 6m47s daemonset-controller Created pod: cilium-b7rrn
Normal SuccessfulCreate 6m47s daemonset-controller Created pod: cilium-wmxlx
```
Verficando o status dos pods
```powershell
k get pods -l k8s-app=cilium -n kube-**system**
k logs -l k8s-app=cilium -n kube-system
```
Se der algum erro em modulo, pode ter faltado algum passo da etapa build do kernel, pode analisar novamente. Pode pegar o nome do modulo que deu erro e tentar carrega-lo, usando modprobe.
Ex:
```bash
sudo modprobe xt_TPROXY
```
Se não der erro e aparecer no lsmod, provalmente só faltar por ele no boot do linux, como foi feito na parte 12 da compilação do kernel.
#### Testando o ambiente.
Para o teste vamos usar o app Star Wars Demo do lab [Getting Started with Cilium](https://isovalent.com/labs/cilium-getting-started/) da Isovalent.
Neste lab, fazemos o deploy de um microserviço simples, temos um deployment chamado DeathStar, que vai receber as requisições POST dos pods xwing e tiefigher, vamos usar o Cilium para controlar a comunicação entre os pods, baseando-se nos labels configurados.
Os Labels:
- Death Star: `org=empire, class=deathstar`
- Imperio TIE fighter: `org=empire, class=tiefighter`
- Rebel X-Wing: `org=alliance, class=xwing`
Vamos usar criar o app no cluster usando o yaml [`http-sw-app.yaml`](https://raw.githubusercontent.com/cilium/cilium/HEAD/examples/minikube/http-sw-app.yaml):.
```yaml
k apply -f https://raw.githubusercontent.com/cilium/cilium/HEAD/examples/minikube/http-sw-app.yaml
```
Checando a criação dos recursos.
```powershell
$cris /kind ❱❱ k get pod,deploy,svc
NAME READY STATUS RESTARTS AGE
pod/deathstar-689f66b57d-9c92f 1/1 Running 0 29m
pod/deathstar-689f66b57d-b4ps7 1/1 Running 0 29m
pod/tiefighter 1/1 Running 0 29m
pod/xwing 1/1 Running 0 29m
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/deathstar 2/2 2 2 29m
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/deathstar ClusterIP 10.96.120.87 <none> 80/TCP 29m
service/kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 130m
```
O manifesto cria também um serviço para gerenciar a comunicação com a DeathStar, vamos usar o exec para simular que estamos execuntando o comando a partir dos pods xwing.
```powershell
k exec tiefighter -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
k exec xwing -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
```
No momento sem politicas ativas, as duas naves podem pousar e a api responde "Ship landed"
Vamos criar uma politica usando o cilium, abaixo o manifesto da politica, vamos fazer um bloqueio simples de porta.
Essa politica abaixo atua nas camadas de rede 3 e 4, em suma podemos controlar IP e Porta.
```yaml
apiVersion: "cilium.io/v2"
kind: CiliumNetworkPolicy
metadata:
name: "rule1"
spec:
description: "L3-L4 policy to restrict deathstar access to empire ships only"
# definindo o pod que vai receber a requisição (No caso a DeathStar)
endpointSelector:
matchLabels:
org: empire
class: deathstar
ingress:
# definindo a origem da conexão, somente permitindo o pod com o label org = empire de acessar na porta 80.
- fromEndpoints:
- matchLabels:
org: empire
toPorts:
- ports:
- port: "80"
protocol: TCP
```
Aplicando a política.
```powershell
k apply -f https://raw.githubusercontent.com/cilium/cilium/HEAD/examples/minikube/sw_l3_l4_policy.yaml
```
Testando as politicas
```powershell
k exec xwing -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
k exec tiefighter -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
```
Agora só o tiefighter recebe o retorno da API, o xwing não consegue conectar, pode dar um CTRL+C para sair.
Agora queremos que o tiefighter somente use a área de pouso, nossa api tem outros endpoints, mas somente queremos que utilize o /request-landing, para isso precisamos criar um regra de HTTP, como nas regras de cama 3 e 4 só trabalhamos com ip e porta, vamos precisar criar uma regra de camada 7, para controlar o tráfego http:
Endpoints:
```powershell
$cris /kind ❱❱ k exec tiefighter -- curl -s -get deathstar.default.svc.cluster.local/v1
{
"name": "Death Star",
"hostname": "deathstar-689f66b57d-9c92f",
"model": "DS-1 Orbital Battle Station",
"manufacturer": "Imperial Department of Military Research, Sienar Fleet Systems",
"cost_in_credits": "1000000000000",
"length": "120000",
"crew": "342953",
"passengers": "843342",
"cargo_capacity": "1000000000000",
"hyperdrive_rating": "4.0",
"starship_class": "Deep Space Mobile Battlestation",
"api": [
"GET /v1",
"GET /v1/healthz",
"POST /v1/request-landing",
"PUT /v1/cargobay",
"GET /v1/hyper-matter-reactor/status",
"PUT /v1/exhaust-port"
]
}
```
Para ajustar o yaml para controlar o trafego http, simplesmente adicionamos o campo rules no manifesto, adicionando mais refino da politica.
```yaml
apiVersion: "cilium.io/v2"
kind: CiliumNetworkPolicy
metadata:
name: "rule1"
spec:
description: "L7 policy to restrict access to specific HTTP call"
endpointSelector:
matchLabels:
org: empire
class: deathstar
ingress:
- fromEndpoints:
- matchLabels:
org: empire
toPorts:
- ports:
- port: "80"
protocol: TCP
rules:
http:
- method: "POST"
path: "/v1/request-landing"
```
Antes de ter politicas, conseguimos facilmente destruir a DeathStar.
```powershell
$cris /kind ❱❱ k exec tiefighter -- curl -s -XPUT deathstar.default.svc.cluster.local/v1/exhaust-port
Panic: deathstar exploded
goroutine 1 [running]:
main.HandleGarbage(0x2080c3f50, 0x2, 0x4, 0x425c0, 0x5, 0xa)
/code/src/github.com/empire/deathstar/
temp/main.go:9 +0x64
main.main()
/code/src/github.com/empire/deathstar/
temp/main.go:5 +0x85
```
Aplicando a politica
```powershell
k apply -f https://raw.githubusercontent.com/cilium/cilium/HEAD/examples/minikube/sw_l3_l4_l7_policy.yaml
```
Testando.
```powershell
k exec tiefighter -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
k exec tiefighter -- curl -s -XPUT deathstar.default.svc.cluster.local/v1/exhaust-port
```
Continuamos conseguindo pousar, mas a porta de exaustão está protegida contra Tiefighters.
```powershell
$cris /kind ❱❱ k exec tiefighter -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
Ship landed
$cris /kind ❱❱ k exec tiefighter -- curl -s -XPUT deathstar.default.svc.cluster.local/v1/exhaust-port
Access denied
```

```
**Cara Pertama**
Kita akan menggunakan event _mouseover_ dan _mouseout_ serta memanfaatkan DOM traversal _closest_. Untuk _closest_ sudah pernah kita gunakan pada proyek sebelumnya, saya sendiri juga termasuk yang baru mengetahui metode _closest_ ini, kalau dari MDN docs penjelasannya sebagai berikut :
> The closest() method of the Element interface traverses the element and its parents (heading toward the document root) until it finds a node that matches the specified CSS selector. Return value : the closest ancestor Element or itself, which matches the selectors. If there are no such element, null.
Jadi penjelasan singkatnya metode _closest_ mencari keatas (parent/anchestor) sampai menemukan selector yang dicari atau dirinya sendiri
```javascript
// app.js
menu.addEventListener('mouseover', (e) => {
if (e.target.classList.contains('link')) {
// menentukan target
const link = e.target;
// menentukan menu lain selain target
const siblings = link.closest('.menu').querySelectorAll('.link');
// jika menu lain bukan target (tidak terkena mouseover) maka opacity diset 0.2
siblings.forEach((el) => {
if (el !== link) el.style.opacity = 0.2;
});
}
});
menu.addEventListener('mouseout', (e) => {
if (e.target.classList.contains('link')) {
const link = e.target;
const siblings = link.closest('.menu').querySelectorAll('.link');
siblings.forEach((el) => {
if (el !== link) el.style.opacity = 1;
});
}
});
```
Hasilnya
**Cara kedua**
Kita akan mencoba me-refactor kode diatas supaya lebih rapi karena ada kode yang berulang (rekursif). Untuk refactor kita buat fungsi baru
```javascript
// refactor
const handleOver = function (e, opacity) {
if (e.target.classList.contains('link')) {
const link = e.target;
const siblings = link.closest('.menu').querySelectorAll('.link');
siblings.forEach((el) => {
if (el !== link) el.style.opacity = opacity;
});
}
};
menu.addEventListener('mouseover', handleOver(e, 0.5));
menu.addEventListener('mouseout', handleOver(e, 1));
```
Kode diatas akan menghasilkan error sebagai berikut
Kenapa ? Karena metode addEventListener memerlukan sebuah fungsi untuk parameter keduanya, bukan sembarang variabel. Maka kita akan mem-passing fungsi sebagai berikut (hasilnya sama dengan diatas jadi saya tidak akan memperlihatkan)
```javascript
const menu = document.querySelector('.menu');
menu.addEventListener('mouseover', function (e) {
handleOver(e, 0.2);
});
menu.addEventListener('mouseout', function (e) {
handleOver(e, 1);
});
```
**Cara ketiga**
Cara terakhir kita akan menggunakan bind method yang juga pernah kita bahas [disini](https://dev.to/boibolang/call-apply-bind-javascript-167k). Bind method akan mengembalikan (return) fungsi yang dengan atribut/keyword 'this' yang bisa diisi nilai apapun
```javascript
const handleOver = function (e) {
if (e.target.classList.contains('link')) {
const link = e.target;
const siblings = link.closest('.menu').querySelectorAll('.link');
siblings.forEach((el) => {
if (el !== link) el.style.opacity = this;
});
}
};
menu.addEventListener('mouseover', handleOver.bind(0.2));
menu.addEventListener('mouseout', handleOver.bind(1));
```
Argument pada bind hanya bisa diisi single value, apabila membutuhkan lebih bisa passing data berupa array | boibolang | |

1,794,195 | Tackling the Cloud Resume Challenge | Introduction In this article, I give an overview of the steps and challenges I underwent... | 0 | 2024-06-12T15:47:47 | https://dev.to/chxnedu/tackling-the-cloud-resume-challenge-ejo | cloud, devops, iac, aws | ## Introduction
In this article, I give an overview of the steps and challenges I underwent to complete the Cloud Resume Challenge.
After learning much about AWS and various DevOps tools, I decided it was time to build real projects so I started searching for good projects to implement. While searching, I came across the [Cloud Resume Challenge](https://cloudresumechallenge.dev/) by Forrest Brazeal and decided to try it out.
The Cloud Resume Challenge is a hands-on project designed to help bridge the gap from cloud certification to cloud job. It incorporates many skills that real cloud and DevOps engineers use daily.
This challenge involves hosting a personal resume website with a visitor counter on Amazon s3, configuring HTTPS and DNS, and setting up CI/CD for deployment. Sounds easy right? That's an oversimplification of the project. In reality, it involves interacting with a lot of tools and services. As a DevOps Engineer, all interactions with AWS should be done with IaC.
I will divide this post into 3 sections;
- FrontEnd
- Backend
- IaC and CI/CD
## FrontEnd
The FrontEnd part of the project involved the following steps;
1. **Designing the FrontEnd with HTML and CSS**
To design the FrontEnd, I took HTML and CSS crash courses to understand the fundamentals which helped me design a basic resume page. I am not a designer by any means or someone with an artistic eye, so my original design was as horrible as expected.
After seeing how ugly and bland the site was, I decided to go with an already made [template](https://www.themezy.com/free-website-templates/151-ceevee-free-responsive-website-template). Deciding to use this template brought about a problem later on in the project which I will get into in the IaC section.
After making the necessary edits to the template, my site was ready, and it was time to move to the next step.
2. **Hosting on Amazon S3 as a static website**
To interact with AWS, I created an IAM user specifically for the project and gave that user access to only the required tools to enhance security. I created an S3 bucket and manually uploaded the files for my website, configured the bucket to host a static website and got the output URL. That was okay for hosting the site, but the project requires you to go further by using a custom domain name.
3. **Configuring HTTPS and DNS**
I registered my domain name with Whogohost, a local Hosting and Domain Registration Company and used Amazon Certificate Manager to request an SSL/TLS certificate for my domain. I also set up a CloudFront distribution to cache content and improve security by redirecting HTTP traffic to HTTPS. After doing all that, my domain name still wasn't pointing to my resume site so I did some digging and found that you have to create a CNAME record with your DNS provider that points that domain to the CloudFront distribution.
*images of Cloudfront and ACM*
My website [https://resume.chxnedu.online](https://resume.chxnedu.online) was finally accessible and online.
The result of the FrontEnd section is a static resume website with an HTTPS URL that points to a CloudFront Distribution.
## BackEnd
The BackEnd section of the project involves setting up a DynamoDB table to store and update the visitor count, setting up an API as an intermediary between the web app and the database, writing Python code for a lambda function that will save a value to the DynamoDB table, and writing tests to ensure the API is always functional. The steps I took;
1. Setting up the DynamoDb table
The DynamoDB table was simple. It just needs to hold the value of the visitor count. I used the AWS Console to create the table, then created an item and gave it a number attribute with the value of 1.
2. Setting up the Lambda function and writing Python code
Lambda is an event-driven, serverless computing platform provided by AWS. It is perfect for this use case because it only needs to run when the website is visited which will trigger the visitor counter. I created a lambda function and used Python to write the [code](https://github.com/Chxnedu/Cloud-Resume-Challenge-AWS-BACKEND/blob/master/python/lambda_code.py). The Python code updates the visitor counter's value by 1 and displays the new value as output. After testing the code and confirming it works as expected, I needed to find the right trigger for the lambda function.
3. Placing an API Gateway in front of the lambda function
Having the javascript code directly communicate with the DynamoDB table is not a good practice, and that's why we created the Lambda function to update the table. Instead of having the javascript code directly trigger the lambda function, an API is implemented. This API ensures that a call to an endpoint by the javascript code triggers the lambda function to run and outputs the new value of the visitor counter. I used AWS API Gateway to create the API and configured an */update_count* endpoint, which when called, triggers the Lambda function to run.
4. Setting up alarms and Writing a good test for the API
As an engineer, you always need to know when your code encounters an issue, and you can't be checking your deployment every minute of the day. Some tools will monitor your deployment and alert you when errors are encountered. To monitor my deployment I used AWS CloudWatch because of how it easily integrates with AWS services. The metrics I configured CloudWatch to alert me about;
- The function invocation crashes or throws an error
- The latency or response time is longer than usual
- The Lambda function is invoked many times in a short period.
I set the three alarms up on CloudWatch and tested the first metric by changing my code a bit, and it worked.
5. Writing Javascript code for the visitor counter
To write the Javascript code, I took a crash course and did a lot of research. I wrote a short [javascript code](https://github.com/Chxnedu/Cloud-Resume-Challenge-AWS/blob/master/Files/js/countcode.js) that fetches the current visitor count from the API endpoint and displays it on the website.
After I completed those steps, the FrontEnd and the BackEnd were seamlessly integrated, and a visit to the website will update the visitor counter and display the current count.
## IaC and CI/CD
All my interactions with AWS have been through the web console, and as a DevOps engineer that is unacceptable.
I created separate repositories to store my [FrontEnd](https://github.com/Chxnedu/Cloud-Resume-Challenge-AWS) and [Backend](https://github.com/Chxnedu/Cloud-Resume-Challenge-AWS-BACKEND) files and configured GitHub Actions in each repository to run Terraform and a Cypress test. Terraform Cloud was used for the backend because of the seamless integration with my GitHub repository.
While writing Terraform configurations for my resources, I encountered the problem mentioned earlier in the article.
After creating an S3 bucket with Terraform, the files need to be uploaded to the bucket and that is done so by creating a Terraform resource for each file. Now I have a whole file tree that I need to upload, which meant I would have to do that manually for each file and folder. After some research and digging, I found a [blog post](https://barneyparker.com/posts/uploading-file-trees-to-s3-with-terraform/) that shows how to upload file trees cleverly using some Terraform functions. I implemented this method and had the whole file tree uploaded to the S3 bucket.
Using GitHub Actions, a push to each repository triggers a run that applies my Terraform configuration and runs a Cypress test.
With all these setups, I successfully implemented the Cloud Resume Challenge with a DevOps spin.

Given four integer arrays nums1, nums2, nums3, and nums4 all of length n, return the number of tuples (i, j, k, l) such that:
0 <= i, j, k, l < n
nums1[i] + nums2[j] + nums3[k] + nums4[l] == 0
Example 1:
Input: nums1 = [1,2], nums2 = [-2,-1], nums3 = [-1,2], nums4 = [0,2]
Output: 2
Explanation:
The two tuples are:
1. (0, 0, 0, 1) -> nums1[0] + nums2[0] + nums3[0] + nums4[1] = 1 + (-2) + (-1) + 2 = 0
2. (1, 1, 0, 0) -> nums1[1] + nums2[1] + nums3[0] + nums4[0] = 2 + (-1) + (-1) + 0 = 0
Example 2:
Input: nums1 = [0], nums2 = [0], nums3 = [0], nums4 = [0]
Output: 1
[Original Page](https://leetcode.com/problems/4sum-ii/description/)
A direct way to solve the problem but it will cause `Time Limit Exceeded` Because it is O(n^4) lol... crazy！
```
public int fourSumCount(int[] nums1, int[] nums2, int[] nums3, int[] nums4) {
int count = 0;
for(int i:nums1){
for(int j:nums2){
for(int k: nums3){
for(int l: nums4){
if(i+j+k+l == 0){
count++;
}
}
}
}
}
return count;
}
```
```
public int fourSumCount(int[] nums1, int[] nums2, int[] nums3, int[] nums4) {
int count = 0;
Map<Integer,Integer> map = new HashMap<>();
for(int i:nums1){
for(int j:nums2){
// record the number of corrolation [1,1] [2,0] are the same
map.put(i+j,map.getOrDefault(i+j, 0) + 1);
}
}
for(int i:nums3){
for(int j : nums4){
int target = 0 - i -j;
count += map.getOrDefault(target, 0);
}
}
return count;
}
```
time: O(n^2), space: O(n)
`getOrDefault` is a very useful function
I think I should pay some attention to Java's collection's function.

## LeetCode No.15 3Sum
Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j != k, and nums[i] + nums[j] + nums[k] == 0.
Notice that the solution set must not contain duplicate triplets.
Example 1:
Input: nums = [-1,0,1,2,-1,-4]
Output: [[-1,-1,2],[-1,0,1]]
Explanation:
nums[0] + nums[1] + nums[2] = (-1) + 0 + 1 = 0.
nums[1] + nums[2] + nums[4] = 0 + 1 + (-1) = 0.
nums[0] + nums[3] + nums[4] = (-1) + 2 + (-1) = 0.
The distinct triplets are [-1,0,1] and [-1,-1,2].
Notice that the order of the output and the order of the triplets does not matter.
Example 2:
Input: nums = [0,1,1]
Output: []
Explanation: The only possible triplet does not sum up to 0.
Example 3:
Input: nums = [0,0,0]
Output: [[0,0,0]]
Explanation: The only possible triplet sums up to 0.
[Original Page](https://leetcode.com/problems/3sum/description/)
Use a direct thought to write it first. But this is the **wrong code**
```
public List<List<Integer>> threeSum(int[] nums) {
List<List<Integer>> list = new ArrayList<>();
for(int i = 0; i < nums.length - 2; i++) {
for(int j = i + 1; j < nums.length - 1; j++) {
for(int k = j + 1; k < nums.length; k++) {
if(nums[i] + nums[j] + nums[k] == 0) {
list.add(Arrays.asList(nums[i], nums[j], nums[k]));
}
}
}
}
return list;
}
```
But this will cause some trouble containing duplicated result tuples e.g. [0,-1,1] and [-1,0,1] will be the same tuple in this question so we have to optimize the above code to achieve AC.
Using a double vector method may help because it is really difficult to conduct the problem that the array is not in-order as well as the we need to remove duplication
```
public List<List<Integer>> threeSum(int[] nums) {
Arrays.sort(nums);
if(nums[0] > 0){
return new ArrayList<>();
}
List<List<Integer>> list = new ArrayList<>();
for(int i = 0; i < nums.length - 2; i++) {
if(nums[i] > 0){
return list;
}
// nums[i] == nums[i-1] and nums[i] == nums[i+1] will lead to different result !!!!!
if(i-1>=0 && nums[i] == nums[i-1]){
continue;
}
int left = i+1;
int right = nums.length-1;
// left < right means left must less than nums.length-1 because max right is nums.length-1 and right will decrease
while(left<right ){
int sum = nums[i] + nums[left] + nums[right];
if(sum > 0){
while(left<right && nums[right-1]==nums[right]){
right--;
}
right--;
}else if(sum<0){
while(left<right && nums[left+1] == nums[left]){
left++;
}
left++;
}else{
list.add(Arrays.asList(nums[i], nums[left], nums[right]));
while(left<right && nums[right-1]==nums[right]){
right--;
}
while(left<right && nums[left+1] == nums[left]){
left++;
}
right --;
left ++;
}
}
}
return list;
}
```
the first version is not fine enough so I want to improve it
here we see that the inner `while` loop is for remove duplication for example [-1,-1,-1,-1,0,1,2,2,2,2]
if i=0 we have -1 so now left and right are -1 and 2 separately and the index of left and right is 1 and length-1 separately and our first result is [-1,-1,2].
but if we move the left to the right and move the right to the left
(index 0f left and right now is 2 and length-2) the result is the same result [-1,-1,2], and we do not want to see it. we want to cut these same elements down so we find left and right until get the different numbers.
This is the basic logic.
But we should be careful
- the sum of them <0 means left is too small we only shift left to the right
- the sum of them > 0 means the right is too large so we only move right to the left
- =0 means we find the result and we should save the result now.
(We have removed the `i` duplicated element by using another inner loop)
so here the 2 inner loops is redundant because whatever happens, the out loop will continue because the inner loop's work can be replaced by out loop
```
Arrays.sort(nums);
if(nums[0] > 0){
return new ArrayList<>();
}
List<List<Integer>> list = new ArrayList<>();
for(int i = 0; i < nums.length - 2; i++) {
if(nums[i] > 0){
return list;
}
// nums[i] == nums[i-1] and nums[i] == nums[i+1] will lead to different result !!!!!
if(i-1>=0 && nums[i] == nums[i-1]){
continue;
}
int left = i+1;
int right = nums.length-1;
// left < right means left must less than nums.length-1 because max right is nums.length-1 and right will decrease
while(left<right ){
int sum = nums[i] + nums[left] + nums[right];
if(sum > 0){
right--;
}else if(sum<0){
left++;
}
else{
list.add(Arrays.asList(nums[i], nums[left], nums[right]));
while(left<right && nums[right-1]==nums[right]){
right--;
}
while(left<right && nums[left+1] == nums[left]){
left++;
}
right--;
left++;
}
}
}
return list;
}
```

1,885,906 | Learn Docker CP Command for Effective File Management | Docker remains at the forefront of container technology, offering developers and operations teams... | 0 | 2024-06-12T15:44:57 | https://www.heyvaldemar.com/learn-docker-cp-command-effective-file-management/ | docker, beginners, devops, learning | Docker remains at the forefront of container technology, offering developers and operations teams alike a robust platform for managing containerized applications. Among the plethora of tools Docker provides, the **`docker cp`** command is particularly invaluable for file operations between the host and containers. This detailed guide elucidates the **`docker cp`** command, enriching it with practical examples and links to official documentation to aid in your DevOps practices.
## Understanding Docker cp
The **`docker cp`** command facilitates the transfer of files and directories to and from Docker containers. It mirrors the functionality of the Unix **`cp`** command but is tailored for the unique environment of containers. Whether you're handling configurations, logs, or data backups, **`docker cp`** ensures that you can efficiently manage files without direct interaction within the container's shell.
### Syntax
```bash
docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH
docker cp [OPTIONS] SRC_PATH CONTAINER:DEST_PATH
```
For detailed syntax and options, refer to the Docker documentation [here](https://docs.docker.com/engine/reference/commandline/cp/).
## When to Use Docker cp
**`docker cp`** is essential in several scenarios:
1. **Debugging:** Quickly extract logs or configuration files to troubleshoot issues within a container.
2. **Data persistence:** Transfer data in/out of containers to ensure that important files are backed up or updated without downtime.
3. **Configuration updates:** Modify configuration files on-the-fly by copying new configuration settings into a running container.
However, it is generally advised to use Docker volumes for persistent data storage as modifications through **`docker cp`** can be lost when containers are restarted. More on managing Docker volumes can be found [here](https://docs.docker.com/storage/volumes/).
## Practical Examples
### Copying Files into a Container
To copy a local file into a container, you might use:
```bash
docker cp /path/to/local/file.txt mycontainer:/path/in/container/file.txt
```
### Extracting Files from a Container
To copy a file from a container to the host:
```bash
docker cp mycontainer:/path/in/container/file.txt /path/to/local/file.txt
```
### Inter-Container File Transfer
While `docker cp` does not support direct file transfers between containers, you can achieve this by copying the file to the host first, then to the destination container:
```bash
docker cp sourcecontainer:/file.txt /tmp/file.txt
docker cp /tmp/file.txt destcontainer:/file.txt
```
## Common Pitfalls and Solutions
1. **Permission Issues:** Ensure the user has appropriate permissions to access the files.
2. **Path Errors:** Verify paths are correct and accessible. Nonexistent paths will halt operations with errors.
## Alternatives to docker cp
For continuous file synchronization or when working with dynamic data, consider using **bind mounts** or **Docker volumes**. These methods link host directories to container directories, allowing for real-time data continuity and less overhead than repetitive **`docker cp`** operations.
```bash
docker run -v /host/data:/container/data myimage
```
This binds the host directory **`/host/data`** to **`/container/data`** inside the container.
## Conclusion
The `docker cp` command is a powerful tool for file management in Docker environments, critical for tasks ranging from simple backups to complex DevOps workflows. By integrating this tool effectively, you can enhance your container management and operational efficiency.
For more insights into Docker commands and best practices, explore the Docker official documentation [here](https://docs.docker.com/).

1,885,896 | Understanding JavaScript Array Methods: forEach, map, filter, reduce, and find | Introduction JavaScript is a versatile language used for creating dynamic and interactive... | 0 | 2024-06-12T15:38:54 | https://dev.to/wafa_bergaoui/understanding-javascript-array-methods-foreach-map-filter-reduce-and-find-2o4f | javascript, development, typescript, webdev | ## **Introduction**
JavaScript is a versatile language used for creating dynamic and interactive web applications. One of its powerful features is the array methods that allow developers to perform a variety of operations on arrays. In this article, we will explore five essential array methods: **forEach**, **map**, **filter**, **reduce**, and **find**. Understanding these methods will help you write cleaner, more efficient, and more readable code.
## **forEach**
**Purpose**
The `forEach` method executes a provided function once for each array element. It is typically used for performing side effects rather than creating new arrays.
**Example**
```javascript
const array = [1, 2, 3, 4];
array.forEach(element => console.log(element));
```
**Explanation**
In the example above, the forEach method iterates over each element of the array and logs it to the console. It does not return a new array; instead, it simply executes the provided function on each element.
## **map**
**Purpose**
The map method creates a new array populated with the results of calling a provided function on every element in the calling array.
**Example**
```javascript
const array = [1, 2, 3, 4];
const doubled = array.map(element => element * 2);
console.log(doubled); // [2, 4, 6, 8]
```
**Explanation**
In this example, map takes each element of the original array, doubles it, and returns a new array with the doubled values. Unlike forEach, map does not modify the original array but creates a new one.
## **filter**
**Purpose**
The filter method creates a new array with all elements that pass the test implemented by the provided function.
**Example**
```javascript
const array = [1, 2, 3, 4];
const even = array.filter(element => element % 2 === 0);
console.log(even); // [2, 4]
```
**Explanation**
Here, filter checks each element of the array to see if it is even. It returns a new array containing only the elements that meet this condition.
## **reduce**
**Purpose**
The reduce method executes a reducer function (that you provide) on each element of the array, resulting in a single output value.
**Example**
```javascript
const array = [1, 2, 3, 4];
const sum = array.reduce((accumulator, currentValue) => accumulator + currentValue, 0);
console.log(sum); // 10
```
**Explanation**
In the reduce example, the method accumulates the sum of all elements in the array. It starts with an initial value of 0 and adds each element to the accumulator, resulting in the total sum.
## **find**
**Purpose**
The find method returns the value of the first element in the provided array that satisfies the provided testing function.
**Example**
```javascript
const array = [1, 2, 3, 4];
const found = array.find(element => element > 2);
console.log(found); // 3
```
**Explanation**
The find method searches through the array and returns the first element that is greater than 2. If no such element is found, it returns undefined.
## **Conclusion**
JavaScript's array methods **forEach**, **map**, **filter**, **reduce**, and **find** are powerful tools that enhance the language's ability to manipulate and process arrays. Each method serves a unique purpose and can significantly simplify common tasks, making your code more readable and efficient. By mastering these methods, you can leverage the full potential of JavaScript arrays in your development projects.

1,885,899 | From Zero to MindMaps... Without Writing a Single Line of Code? 🤯 | The code write by our AI overlords I'll admit it – I’m a lazy programmer at heart. So when I saw... | 0 | 2024-06-12T15:35:10 | https://dev.to/red_54/from-zero-to-mindmaps-without-writing-a-single-line-of-code-32hl | python, ai, beginners, api |
[The code write by our AI overlords](https://github.com/Red-54/MindMap)
I'll admit it – I’m a lazy programmer at heart. So when I saw that viral video where some genius used OpenAI to whip up an app without coding, my inner sloth rejoiced. Could I pull off the same magic with Google’s Gemini and avoid the drudgery of typing?
Challenge accepted! My mission: **build a web app that could magically transform dull documents into beautiful MindMaps, all with the help of AI.** No coding experience required… right?
**Round 1: "Hello World," Says Gemini (and a Mountain of Errors) 💪**
Armed with a blank text file and the unyielding optimism of someone who’s never actually built a web app, I summoned Gemini into my coding arena (aka my chat window).
> “Hey Gemini, my brilliant AI friend, let’s make a Flask app where people can upload documents, and you, with your infinite wisdom, will turn them into glorious Mermaid mindmaps!”
Gemini, bless its silicon soul, responded with a torrent of code snippets, helpful explanations (or so I thought at the time), and a Flask app skeleton. “Cool,” I thought, naively. “This AI stuff is easy!”
**Round 2: The Encoding Labyrinth of Doom 🤯**
The honeymoon phase was short-lived. My first boss battle? Encoding. Gemini dutifully generated Mermaid code, but `mermaid.ink`, the online rendering service I was using, kept spitting back errors.
"Invalid encoded code!" it screamed. "Bad Request!"
Turns out, Base64 encoding wasn't enough. We ventured into the treacherous realm of URL-safe encoding, battled mysterious "pako:" strings from the Mermaid Live Editor, and I swear I saw a hex editor flash before my eyes.
**Round 3: Mermaid Syntax: Where Spaces Are Deadly Weapons ⚔️**
Mermaid diagrams, those elegant visualizers of information, are beautiful… until they're not. Gemini and I spent an eternity (or at least what felt like it) wrangling Mermaid's finicky syntax:
- Missing spaces around arrows: "400 Bad Request!"
- Extra spaces around arrows: "400 Bad Request!"
- The `graph LR` directive: A mystical incantation that sometimes worked and sometimes didn't.
I began to suspect that Mermaid was sentient and enjoyed tormenting me.
**Round 4: The Phantom "Syntax Error" Image 👻**
Just when we thought victory was near, a new terror emerged: the dreaded "Syntax error in text" image. But wait… Gemini was now generating perfectly valid Mermaid code! What dark sorcery was this?!
Enter the villain: browser caching! My browser, like a stubborn mule, refused to let go of the old, error-ridden image. Clearing the cache and performing hard refreshes became my new mantra.
**The Result: A Frankensteinian MVP 🧟♂️**
Bruised, battered, but not entirely broken, I emerged from the AI coding gauntlet with a working app! It was a Frankensteinian creation, cobbled together with duct tape and Gemini's digital sweat.
A diagram that was generated:-
The UI was hideous, performance was slower than a snail in molasses, and I still had nightmares about encoding. But it functioned! And I hadn’t written a single line of “real” code.
**Lessons Learned from the AI-pocalypse:**
- **AI is a powerful tool:** Gemini's ability to generate code, explain concepts, and assist with debugging was impressive.
- **Human skills still matter:** Clear communication, problem-solving, and the ability to understand (and fix!) code are essential.
- **Patience is a virtue:** When working with AI, be prepared for unexpected errors, cryptic messages, and a whole lot of head-scratching.
**The Quest Continues... Manually!**
Now, armed with newfound (and hard-won) knowledge, I'm embarking on a new quest: rebuilding this app from scratch, using my own coding skills. Will I be able to create a better, more refined version? And how will the time and effort compare to the AI-assisted approach? | red_54 |

Machine learning (ML) can seem intimidating at first, but breaking it down into... | 0 | 2024-06-12T15:21:15 | https://dev.to/vidyarathna/getting-started-with-machine-learning-53el | machinelearning, python, beginners, machinelearningbeginners | Hey there!
Machine learning (ML) can seem intimidating at first, but breaking it down into manageable steps can make it more approachable. Here's a practical introduction to help you dive into the world of ML. We'll walk through understanding the basics, setting up your environment, and writing your first piece of code.
First things first, to embark on our machine learning journey, we need to grasp two key concepts: data and algorithms.
**Understanding Data:**
Data is the fuel for machine learning. It's like ingredients for a recipe. We need clean, relevant data to train our model effectively. This could be anything from numbers in a spreadsheet to images of cats and dogs.
**Choosing the Right Algorithm:**
Just like choosing the right tool for the job, selecting the appropriate algorithm is crucial. There are many types of algorithms for different tasks, such as classification, regression, and clustering. We'll start with something simple, like linear regression, to predict numerical values based on input data.
Now, let's get our hands dirty with some code!
**Step 1: Setting Up Your Environment:**
First, make sure you have Python installed on your machine. You can easily install libraries like NumPy, Pandas, and Scikit-learn using pip.
**Step 2: Loading and Preparing Data:**
We'll start by loading our data into Python. For this example, let's use a CSV file containing housing prices and features like square footage and number of bedrooms. We'll use Pandas to load and clean our data, handling any missing values or outliers.
```python
import pandas as pd
# Load the data
data = pd.read_csv('housing_data.csv')
# Clean the data (handle missing values, outliers, etc.)
# Example: data.dropna(), data.fillna(), data.drop_duplicates(), etc.
```
**Step 3: Splitting Data for Training and Testing:**
Before training our model, we need to split our data into two sets: one for training and one for testing. This ensures that our model generalizes well to new, unseen data.
```python
from sklearn.model_selection import train_test_split
X = data[['feature1', 'feature2', ...]] # Features
y = data['target'] # Target variable
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
```
**Step 4: Training the Model:**
Now, let's train our linear regression model using the training data.
```python
from sklearn.linear_model import LinearRegression
model = LinearRegression()
model.fit(X_train, y_train)
```
**Step 5: Evaluating the Model:**
Once trained, we evaluate our model's performance using the testing data.
```python
from sklearn.metrics import mean_squared_error
predictions = model.predict(X_test)
mse = mean_squared_error(y_test, predictions)
print("Mean Squared Error:", mse)
```
And there you have it! A basic introduction to machine learning with practical code examples. Remember, practice makes perfect, so don't hesitate to experiment with different algorithms and datasets.
Happy coding! 🚀 | vidyarathna |

1,885,876 | 75. Sort Colors | 75. Sort Colors Medium Given an array nums with n objects colored red, white, or blue, sort them... | 27,523 | 2024-06-12T15:18:04 | https://dev.to/mdarifulhaque/75-sort-colors-2hjp | php, leetcode, algorithms, programming | 75\. Sort Colors
Medium
Given an array `nums` with `n` objects colored red, white, or blue, sort them [in-place](https://en.wikipedia.org/wiki/In-place_algorithm) so that objects of the same color are adjacent, with the colors in the order red, white, and blue.
We will use the integers `0`, `1`, and `2` to represent the color red, white, and blue, respectively.
You must solve this problem without using the library's sort function.
**Example 1:**
- **Input:** nums = [2,0,2,1,1,0]
- **Output:** [0,0,1,1,2,2]
**Example 2:**
- **Input:** nums = [2,0,1]
- **Output:** [0,1,2]
**Constraints:**
- <code>n == nums.length</code>
- <code>1 <= n <= 300</code>
- `nums[i]` is either `0`, `1`, or `2`.
**Follow-up:** Could you come up with a one-pass algorithm using only constant extra space?
**Constraints:**
```
class Solution {
/**
* @param Integer[] $nums
* @return NULL
*/
function sortColors(&$nums) {
$l = 0;
$r = count($nums) - 1;
for ($i = 0; $i <= $r;) {
if ($nums[$i] == 0) {
list($nums[$i], $nums[$l]) = array($nums[$l], $nums[$i]);
$i++;
$l++;
} elseif ($nums[$i] == 1) {
$i++;
} else {
list($nums[$i], $nums[$r]) = array($nums[$r], $nums[$i]);
$r--;
}
}
}
}

Node.js is a powerful runtime environment that allows you to build scalable and efficient server-side applications. If you have already mastered the basics of Node.js and are looking to level up your skills, it's time to tackle some intermediate projects.
In this article, we will explore three exciting projects that will challenge your understanding of Node.js and help you become a more proficient developer. Without further ado, let's dive right in!
## 1. Build a Real-time Chat Application with Socket.IO
One of the most common use cases for Node.js is building real-time applications such as chat applications. To take it up a notch, we will develop a chat application using Socket.IO.
Socket.IO is a library that enables real-time bidirectional event-based communication between clients and servers. By utilizing WebSockets under the hood, Socket.IO makes building real-time applications effortless.
In this project, we will create multiple chat rooms where users can communicate in real-time with each other. Users will be able to send messages instantly, receive notifications when new messages arrive, and join or leave chat rooms seamlessly.
To get started on this project:
- Install the necessary dependencies including ExpressJS and Socket.IO
- Set up an Express server to handle HTTP requests
- Create routes for handling different API endpoints
- Implement socket communication events such as connecting, disconnecting, sending, and receiving messages
- Style your front end using CSS or popular front-end frameworks like Bootstrap or Tailwind CSS
By implementing this project from scratch, you'll gain hands-on experience with not only Node.js but also WebSockets - an essential technology for any modern developer working on real-time applications.
## 2. Develop a RESTful API With Authentication Using Passport.js
Aspiring backend developers should be well-versed in developing APIs with authentication functionalities. In this project, we'll build an API using REST architecture principles along with passport.js for user authentication.
Passport.js is a popular authentication library that provides a simple and flexible way to implement user authentication in Node.js applications.
In this project, we will:
- Set up a new Express application
- Install passport.js and relevant strategies (such as JWT or OAuth) for authentication
- Configure passport.js with the necessary middleware, serializers, and deserializers
- Develop RESTful routes for CRUD operations on various resources (e.g., users, posts)
- Secure certain API endpoints using the passport's authentication strategies
By completing this project, you'll not only learn how to build scalable REST APIs but also gain proficiency in implementing user authentication techniques - an indispensable skill when working on secure web applications.
## 3. Create an Image Upload Service Using AWS S3
File uploads are fundamental to many web applications. In this project, you'll learn how to create an image upload service that utilizes AWS S3 (Simple Storage Service) for storing uploaded images.
To complete this project successfully:
- Set up an AWS account and create an S3 bucket
- Install the official AWS SDK package for Node.js
- Implement server-side logic to handle file uploads via multipart form data
- Use libraries like multer to simplify handling of multipart form data.
- Use the AWS SDK package functions to interact with the S3 service.
With this project under your belt, you'll not only become adept at handling file uploads in Node.js but also gain hands-on experience with cloud services like Amazon S3.
## Conclusion
These three intermediate projects will push your knowledge of Node.js further while allowing you to explore essential development concepts such as real-time communication, API development with authentication functionalities, and integrating cloud services. Take up these projects one by one or all together – challenge yourself and join the ranks of skilled developers using Node.js!

It... | 0 | 2024-06-12T15:07:25 | https://dev.to/cocodelacueva/artificial-intelligence-is-not-a-feature-4ei5 | webdev, aws, tutorial | Since Chat GPT came out in late 2022, everybody has been talking about Artificial Intelligence. It seems like everything is AI, but it is not.
### What do I mean?
I know Artificial Intelligence has many benefits; it can help with many repetitive tasks and does it faster; and it is letting a lot of people out of their jobs as well. Artificial intelligence is real, and now it is also useful.
However, my point is that you cannot add it anywhere. I mean, you can, but this costs a bunch of money, takes a lot of time, and the most important thing, is it worth it?
Every time we pitch a new project, we come across the typical question; ‘Can you add some Artificial Intelligence here?’
Again, ‘Yes, we can, but to do what?’
It is hard to say that almost every answer is nonsense. Nobody knows what to do with AI, but everybody wants to include it somehow. It is marketing.
And this is happening everywhere. From small companies to huge ones. Everybody has a degree in Artificial intelligence and 10 years of experience making prompts when Chat GPT was released around two or three years ago.
I also have to say that there were a few companies that stopped and thought. It is not a good idea to tell everybody their product is using Artificial Intelligence when the user can’t feel the difference, is it? If it is not useful for the customer, it will fail.
### Can Artificial Intelligence be useful?
Yes, of course, but AI must never be a feature.
It is better to start thinking about what my customers or users want, and not the other way around. What can my product or project do to solve their needs?
Once we know what we have to do, it is time to work. If artificial intelligence can help us to achieve our goals, we will use it.
AI must never be a feature. It is a tool like any other. _It must be used when needed._ | cocodelacueva |

# Keeping Your Cloud Spending in Check: Cost Optimization with AWS Cost Explorer and Budgets 💰
As organizations increasingly embrace cloud computing, managing cloud expenditures becomes paramount. Uncontrolled cloud costs can quickly erode profitability, making cost optimization a critical aspect of any successful cloud strategy. Fortunately, AWS provides a suite of powerful tools designed to help you understand, control, and optimize your cloud spending. Two of the most essential tools in this arsenal are AWS Cost Explorer and AWS Budgets.
### Understanding the Basics: AWS Cost Explorer and AWS Budgets
**AWS Cost Explorer** is a free service that provides an interactive interface for visualizing and analyzing your AWS costs and usage. It empowers you to:
* **Visualize Your Spending:** Explore your AWS costs over time using customizable charts and graphs.
* **Identify Cost Trends:** Analyze historical cost data to uncover patterns and trends in your spending.
* **Forecast Future Costs:** Use historical data to estimate your future AWS costs and plan your budget accordingly.
* **Breakdown Costs:** Dive deep into your spending by service, region, linked account, or other dimensions.
* **Export Data:** Download your cost and usage data in various formats (CSV, PDF) for further analysis or reporting.
**AWS Budgets** complements Cost Explorer by enabling you to set customized cost and usage budgets that align with your financial goals. With AWS Budgets, you can:
* **Set Custom Budgets:** Define budgets for various cost dimensions, including services, accounts, tags, and more.
* **Establish Alerts:** Receive notifications when your spending approaches or exceeds your predefined budget thresholds.
* **Automate Actions:** Trigger automated actions, such as stopping instances or sending notifications, based on budget conditions.
* **Track Coverage:** Monitor your Reserved Instance (RI) utilization and Savings Plans coverage to identify potential cost savings.
### Five Powerful Use Cases for AWS Cost Optimization Tools
1. **Identifying Cost Overruns Before They Happen**
Imagine being notified when your development team's experimental project starts exceeding its allocated budget. This proactive approach is possible with AWS Budgets. You can set up alerts that notify you via email or SNS (Simple Notification Service) when your actual or forecasted costs hit a certain percentage of your defined budget threshold. Early detection empowers you to investigate anomalies and take corrective action promptly, preventing costly surprises at the end of the billing cycle.
2. **Pinpointing Resource-Hungry Applications**
Cost Explorer's powerful filtering and grouping capabilities allow you to zoom in on specific resources or applications that might be consuming more than their fair share of resources. By grouping costs by tags, for instance, you can quickly identify which applications, departments, or environments are the biggest spenders. This granular visibility facilitates targeted optimization efforts, such as rightsizing instances, optimizing data storage, or refining application architecture.
3. **Optimizing Reserved Instance (RI) Utilization**
RIs offer significant cost savings compared to On-Demand instances, but only if you utilize them effectively. Cost Explorer provides insights into your RI utilization, helping you identify underutilized RIs. Armed with this information, you can adjust your instance sizes, modify applications to better leverage RIs, or explore selling unused RIs on the Reserved Instance Marketplace.
4. **Driving Accountability Across Teams**
Breaking down costs by departments or projects using tags allows you to create separate budgets for each team or project. This granular approach fosters a culture of accountability by empowering teams to monitor their spending, identify areas for improvement, and make informed decisions that align with overall budget constraints.
5. **Leveraging Historical Data for Informed Forecasting**
Cost Explorer's historical data analysis capabilities are invaluable for forecasting future costs. By analyzing past spending patterns, you can estimate your future cloud expenditures with a higher degree of accuracy. These forecasts enable you to plan your budget effectively, allocate resources efficiently, and anticipate potential cost increases due to business growth or seasonal fluctuations.
### Exploring Alternative Cloud Cost Management Solutions
While AWS offers comprehensive cost optimization tools, it's worth exploring what other cloud providers bring to the table:
* **Google Cloud Platform (GCP):** GCP's cost management tools include **Cloud Billing**, which provides detailed billing reports and cost analysis features, and **Cloud Monitoring**, which enables you to track resource usage and set alerts for cost-related metrics.
* **Microsoft Azure:** Azure offers **Azure Cost Management and Billing**, a suite of tools for monitoring, analyzing, and optimizing your Azure costs. Key features include cost analysis, budgets, and recommendations for cost optimization.
### Conclusion
Effective cost management is an ongoing process, not a one-time event. By leveraging the power of AWS Cost Explorer, AWS Budgets, and other cloud cost management tools, organizations can gain deep visibility into their cloud spending, identify optimization opportunities, and ultimately drive down their cloud costs without compromising performance or scalability.

1,885,872 | Ethereum (ETH) Takes a Hit Amid Mixed Updates: Analysis | Ethereum products see $69 million net inflows, marking best result since March. Analysing... | 0 | 2024-06-12T15:04:40 | https://dev.to/endeo/ethereum-eth-takes-a-hit-amid-mixed-updates-analysis-3fgi | webdev, javascript, web3, blockchain | #### Ethereum products see $69 million net inflows, marking best result since March. Analysing why this is not a silver lining for Ether.
While Ethereum protocol boasts of promising updates, ETH keeps struggling below $3,700. Sharp downtick in social metrics adds advantage for the bears, yet fundamentals spur optimism in Ether’s prospects. But which factors would be leading in the market sentiment?
## Ethereum Deposits Emptying Despite Positive Address Momentum
Data from Glassnode indicates that the amount of Ether (ETH) held on exchanges has reached its lowest point in eight years.
While this may indicate a decreased speculative interest in Ether, taking place due to post-ETF approval market shock, this marks a strong holding tendency. According to the IntoTheBlock’s data, 89% of Ethereum holders are in profit at the current price, which is a strong indicator of a healthy market.
The data also reveals that Ethereum is mainly held by whales, with 51% of the asset cited to be concentrated on the large holders’ wallets.
What is more, CoinShares recently reported that Ether investment products saw a total inflow of $69 million for the week, hitting the three-month record.
This correlates with a notable increase in a volume of transactions exceeding $100k, which proves the institutional and large-scale investor optimism on the long-term Ethereum perspectives due to its exchange-traded funds’ (ETFs) approval.
By contrast, overall Ethereum’s sentiment has registered a sharp decline since the beginning of the month. Santiment’s data reveals that Ether’s weighted sentiment indicates a negative rate after its surge in the end of May – just around the ETF-fueled spike.
Additionally, an analysis of the social volume showed downticks corresponding to the decreases in weighted sentiment.
Despite the weak sentiment, Ethereum still sees a positive new address momentum. At the writing time, the number of new addresses exceeds 105,000.
## Chart Favors Bears
As per Ether’s daily chart, the asset faced heightened selling activity after a short period of consolidation near the $4,000 crucial resistance. This highlights the price level as a key point for short positions.
Nonetheless, there is a significant support zone ahead, including the 100-day moving average at $3,431.05 and the 0.5 Fibonacci retracement level at $3,419. This suggests that the current price action may continue its bearish retracement in the short term, with the 100-day moving average and the 0.5 Fib level acting as primary support for buyers.
The 4-hour chart indicates a strong sideway movement for Ethereum. According to the graph, the aforementioned consolidation in the $4,000 area has formed a head and shoulders pattern, indicating a lack of bullish momentum and an increase in supply. Consequently, this pattern may signalise an eventual bearish reversal, especially with breaking below the neckline of the formation.
The seller dominance is also marked by a bearish divergence between the relative strength index (RSI) and the price movement.
Currently, the price is at a critical support level of around $3.6K. If sellers manage to breach this pivotal level, continuing the bearish trend is the most likely outcome.
Controversial Ethereum updates only emphasize the vagueness of the coin’s trend. While traders received a perfect opportunity to buy, they should closely monitor the upcoming Federal Reserve’s updates on the interest rates in the US – a crucial factor of influence towards the cryptocurrency market. | endeo |

It seems like everything is AI, but it is not.
What do I mean?
I know Artificial Intelligence has many benefits; it can help with many repetitive tasks and does it faster; and it is letting a lot of people out of their jobs as well. Artificial intelligence is real, and now it is also useful.
However, my point is that you cannot add it anywhere. I mean, you can, but this costs a bunch of money, takes a lot of time, and the most important thing, is it worth it?
Every time we pitch a new project, we come across the typical question; ‘Can you add some Artificial Intelligence here?’
Again, ‘Yes, we can, but to do what?’
It is hard to say that almost every answer is nonsense. Nobody knows what to do with AI, but everybody wants to include it somehow. It is marketing.
And this is happening everywhere. From small companies to huge ones. Everybody has a degree in Artificial intelligence and 10 years of experience making prompts when Chat GPT was released around two or three years ago.
I also have to say that there were a few companies that stopped and thought. It is not a good idea to tell everybody their product is using Artificial Intelligence when the user can’t feel the difference, is it? If it is not useful for the customer, it will fail.
Can Artificial Intelligence be useful?
Yes, of course, but AI must never be a feature.
It is better to start thinking about what my customers or users want, and not the other way around. What can my product or project do to solve their needs?
Once we know what we have to do, it is time to work. If artificial intelligence can help us to achieve our goals, we will use it.
AI must never be a feature. It is a tool like any other. It must be used when needed.

Creating a responsive application plays an important role in providing a consistent user interface that dynamically adjusts and displays properly on different devices. A cross-platform responsive UI enhances UX by ensuring consistent, optimized interactions on both mobile and web.
Unistyles and Tamagui are two [React Native styling libraries](https://blog.logrocket.com/tamagui-react-native-create-faster-design-systems/) that you can use to create cross-platform styles that works on both mobile and web applications. These two libraries address the challenges of creating consistent and responsive styles across different mobile devices.
In this article, we will explore Unistyles and Tamagui and compare them with each other.
## What is Unistyles?
[Unistyles is a cross-platform library](https://reactnativeunistyles.vercel.app/) designed to streamline style management within React Native applications. You can use Unistyles to create styles that are compatible and supported across different platforms, such as iOS, Android, React Native Web, macOS, and Windows.
The Unistyles library is built on top of the default [React Native StyleSheet](https://blog.logrocket.com/react-native-styling-tutorial-examples/), making it easy to transition to Unistyles if you’re already familiar with React Native and working with the StyleSheet. It comes with notable features such as breakpoints, theming, media queries, and cross-platform support, among others.
To install Unistyles into your React Native project, open your terminal, navigate to the project directory, and run the command below:
```bash
npm install react-native-unistyles
cd ios && pod install
```
Unistyles has many benefits for mobile development. Some of the pros of Unistyles include:

* It lacks prebuilt UI component kits
## Unistyles usage example
Let’s see a demo of how to use Unistyles to style your React Native application. Open the `App.tsx` file and add the following code:
```typescript
import React from 'react';
import { View, Text, TouchableOpacity, Platform } from 'react-native';
import { useStyles } from 'react-native-unistyles';
// Define your styles with platform-specific adjustments
const MyStyles = {
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: Platform.select({
ios: 'lightblue',
android: 'lightgreen',
default: 'white', // Default for other platforms
}),
},
text: {
fontSize: 30,
color: 'red',
padding: Platform.select({
ios: 10,
android: 20,
default: 15, // Default for other platforms
}),
},
button: {
paddingVertical: Platform.select({
ios: 12,
android: 16,
default: 14, // Default for other platforms
}),
paddingHorizontal: 24,
backgroundColor: Platform.select({
ios: 'dodgerblue',
android: 'green',
default: 'gray', // Default for other platforms
}),
borderRadius: 5,
marginTop: 20,
},
buttonText: {
fontSize: 18,
color: 'white',
},
};
const App = () => {
// Initialize useStyles with the defined styles
const { styles, breakpoint, theme } = useStyles(MyStyles);
// Log the styles, breakpoint, and theme for debugging
console.log({ styles, breakpoint, theme });
return (
<View style={styles.container}>
<Text style={styles.text}>Cross-Platform Styling Example</Text>
<TouchableOpacity style={styles.button}>
<Text style={styles.buttonText}>Press Me</Text>
</TouchableOpacity>
</View>
);
};
export default App;
```
The above code will produce the following result: 
## What is Tamagui?
[Tamagui is a UI library](https://tamagui.dev/) that makes it easier for you to build UIs for React Native apps that work on both mobile and web platforms. It provides a suite of pre-built components, a powerful styling system, theming capabilities, and media queries for designing responsive applications.
One of Tamagui's standout features is its ability to share styles between web and native apps without compromising the app's performance or code quality. Also, Tamagui optimizes the process of rendering styled components by simplifying them into platform-specific elements — that is, `div` elements for the web and `Views` for native platforms.
To get started with Tamagui, install the library by running the command below in your React Native project directory:
```bash
npm install tamagui @tamagui/core @tamagui/config
```
Then, to configure Tamagui, navigate to the root folder of the project, create a configuration file named `tamagui.config.ts`, and add the following code:
```typescript
import { createTamagui } from "tamagui";
import { config } from "@tamagui/config";
export default createTamagui(config);
```
Tamagui has its own set of pros and cons. Some of the benefits of Tamagui include:
* It features an inbuilt compiler (`@tamagui/static`) for performance optimization
* Developers can utilize pre-built styled UI components, eliminating the need to design them from scratch
* It has a flexible styling system that supports dynamic theming, making it easy to switch between themes
Some cons of Tamagui you should know are:
* It does not support plugins, making it difficult to extend its functionality
* Setting up Tamagui in an Expo app is not straightforward; it requires additional configuration
## Tamagui usage example
Let's demonstrate how to use the [AlertDialog](https://tamagui.dev/ui/alert-dialog/1.0.0) component from Tamagui UI in a React Native application. To do that, open the `app.js` file and add the following code:
```javascript
import { View, StyleSheet, Text } from "react-native";
import { AlertDialog, Button, XStack, YStack } from "tamagui";
import { TamaguiProvider } from "tamagui";
import config from "./tamagui.config";
import { StatusBar } from "expo-status-bar";
export default function App() {
return (
<TamaguiProvider config={config}>
<View style={styles.container}>
<Header />
<AlertDialogDemo />
<StatusBar style="auto" />
</View>
</TamaguiProvider>
);
}
function Header() {
return (
<View style={styles.header}>
<Text style={styles.headerText}>Welcome to Tamagui Alert Demo</Text>
</View>
);
}
function AlertDialogDemo() {
return (
<AlertDialog native>
<AlertDialog.Trigger asChild>
<Button style={styles.showAlertButton}>Show Alert</Button>
</AlertDialog.Trigger>
<AlertDialog.Portal>
<AlertDialog.Overlay />
<AlertDialog.Content>
<YStack space>
<AlertDialog.Title>Accept</AlertDialog.Title>
<AlertDialog.Description>
By pressing yes, you accept our terms and conditions.
</AlertDialog.Description>
<XStack space="$3" justifyContent="flex-end">
<AlertDialog.Cancel asChild>
<Button style={styles.cancelButton}>Cancel</Button>
</AlertDialog.Cancel>
<AlertDialog.Action asChild>
<Button theme="active" style={styles.acceptButton}>
Accept
</Button>
</AlertDialog.Action>
</XStack>
</YStack>
</AlertDialog.Content>
</AlertDialog.Portal>
</AlertDialog>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "#f8f9fa",
alignItems: "center",
justifyContent: "center",
padding: 20,
},
});
```
Save the above code and start the application. You will see the following output: 
## Similarities between Unistyles and Tamagui
Unistyles and Tamagui are both cross-platform style libraries that work on both mobile and web applications, making it easy to build cross-platform, responsive, and user-friendly application interfaces that are easy to maintain.
Both Unistyles and Tamagui support server-side rendering and component rendering, respectively. This enables developers to create web applications with improved SEO and faster page loading by rendering styles on the server side.
While Tamagui might have a larger community currently, both libraries have active communities that provide support through documentation, forums, or discussion channels.
Both libraries also support media queries, enabling developers to define styles that apply only to specific screen sizes or device orientations. This ensures that the app displays and functions well on different devices.
## Unistyles vs. Tamagui: Differences
Let’s discuss the notable differences between Unistyles and Tamagui to determine which of these two cross-platform libraries is suitable for your React Native application.
### Customization
Unistyles is a low-level styling library that enables developers to create custom designs compatible with both mobile and web apps from scratch. You can use a toolbox of reusable CSS classes for precise control.
On the other hand, Tamagui is a UI library featuring pre-built styled components, enabling developers to design interfaces effortlessly by leveraging built-in elements like buttons, forms, and panels, eliminating the need to develop custom components from scratch.
Unistyles is suitable for projects requiring maximum flexibility and highly customized UIs. Meanwhile, Tamagui is a good fit for projects that prioritize faster development and a consistent look and feel.
### Plugins
Unistyles allows you to use plugins to easily extend your app’s functionality and customize the styling behavior. The plugin accepts defined style objects and returns a new style object that you can use to apply new features to elements or components within the application.
As for Tamagui, it doesn’t currently support a plugin system, which means we can't extend its functionality or alter its styling behavior as easily as with Unistyles plugins.
### Popularity
Unistyles was released in October 2023 and quickly reached a 6 percent usage rate within the first three months, according to the [State of React Native survey](https://results.stateofreactnative.com/styling/). This percentage shows how developers are adapting to the library.
Tamagui has been around a little longer than Unistyles and had a 6 percent usage rate for the 2022 calendar year. This usage rate increased to 19 percent in 2023 due to its growing popularity among developers.
The image below — which comes from the State of React Native survey results — shows the usage percentages of the most-used React Native style libraries for the years 2022 and 2023: 
### Performance
Unistyles is a fast styling library that offers low-level customization, rendering 1000 views with all its features in 46.5ms. While slightly slower than StyleSheet, it still outperforms most React Native style libraries.
Tamagui is a fast UI library that uses its `@tamagui/static` core compiler to optimize styled components. This helps improve performance by hoisting objects and CSS at build-time, resulting in flatter React trees.

1,883,314 | OOPs Concept: getitem, setitem & delitem in Python | Python has numerous collections of dunder methods(which start with double underscores and end with... | 0 | 2024-06-12T15:01:00 | https://geekpython.in/implement-getitem-setitem-and-delitem-in-python | oop, objectorientedprogramming, python | Python has numerous collections of dunder methods(which start with double underscores and end with double underscores) to perform various tasks. The most commonly used dunder method is `__init__` which is used in Python classes to create and initialize objects.
In this article, we'll see the usage and implementation of the underutilized dunder methods such as `__getitem__`, `__setitem__`, and `__delitem__` in Python.
## **\_\_getitem**\_\_
The name **getitem** depicts that this method is used to access the items from the list, dictionary and array.
If we have a list of names and want to access the item on the third index, we would use `name_list[3]`, which will return the name from the list on the third index. When the `name_list[3]` is evaluated, Python internally calls `__getitem__` on the data (`name_list.__getitem__(3)`).
The following example shows us the practical demonstration of the above theory.
```python
# List of names
my_list = ['Sachin', 'Rishu', 'Yashwant', 'Abhishek']
# Accessing items using bracket notation
print('Accessed items using the bracket notation')
print(my_list[0])
print(my_list[2], "\n")
# Accessing items using __getitem__
print('Accessed items using the __getitem__')
print(my_list.__getitem__(1))
print(my_list.__getitem__(3))
```
We used the commonly used bracket notation to access the items from the `my_list` at the `0th` and `2nd` index and then to access the items at the `1st` and `3rd` index, we implemented the `__getitem__` method.
```bash
Accessed items using the bracket notation
Sachin
Yashwant
Accessed items using the __getitem__
Rishu
Abhishek
```
### Syntax
`__getitem__(self, key)`
The \_\_**getitem**\_\_ is used to evaluate the value of `self[key]` by the object or instance of the class. Just like we saw earlier, `object[key]` is equivalent to `object.__getitem__(key)`.
`self` - object or instance of the class
`key` - value we want to access
### \_\_getitem\_\_ in Python classes
```python
# Creating a class
class Products:
def __getitem__(self, items):
print(f'Item: {items}')
item = Products()
item['RAM', 'ROM']
item[{'Storage': 'SSD'}]
item['Graphic Card']
```
We created a Python class named `Products` and then defined the `__getitem__` method to print the `items`. Then we created an instance of the class called `item` and then passed the values.
```bash
Item: ('RAM', 'ROM')
Item: {'Storage': 'SSD'}
Item: Graphic Card
```
These values are of various data types and were actually parsed, for example, `item['RAM', 'ROM']` was parsed as a tuple and this expression was evaluated by the interpreter as `item.__getitem__(('RAM', 'ROM'))`.
Checking the type of the item along with the items.
```python
import math
# Creating a class
class Products:
# Printing the types of item along with items
def __getitem__(self, items):
print(f'Item: {items}. Type: {type(items)}')
item = Products()
item['RAM', 'ROM']
item[{'Storage': 'SSD'}]
item['Graphic Card']
item[math]
item[89]
```
**Output**
```bash
Item: ('RAM', 'ROM'). Type: <class 'tuple'>
Item: {'Storage': 'SSD'}. Type: <class 'dict'>
Item: Graphic Card. Type: <class 'str'>
Item: <module 'math' (built-in)>. Type: <class 'module'>
Item: 89. Type: <class 'int'>
```
### Example
In the following example, we created a class called `Products`, an `__init__` that takes `items` and a `price`, and a `__getitem__` that prints the value and type of the value passed inside the indexer.
Then we instantiated the class `Products` and passed the arguments `'Pen'` and `10` to it, which we saved inside the `obj`. Then, using the instance `obj`, we attempted to obtain the values by accessing the parameters `items` and `price`.
```python
# Creating a class
class Products:
# Creating a __init__ function
def __init__(self, items, price):
self.items = items
self.price = price
def __getitem__(self, value):
print(value, type(value))
# Creating instance of the class and passing the values
obj = Products('Pen',10)
# Accessing the values
obj[obj.items]
obj[obj.price]
```
**Output**
```bash
Pen <class 'str'>
10 <class 'int'>
```
## \_\_setitem\_\_
The `__setitem__` is used to assign the values to the item. When we assign or set a value to an item in a list, array, or dictionary, this method is called internally.
Here's an example in which we created a list of names, and attempted to modify the list by changing the name at the first index (`my list[1] = 'Yogesh'`), and then printed the updated list.
To demonstrate what the interpreter does internally, we modified the list with the help of `__setitem__`.
```python
# List of names
my_list = ['Sachin', 'Rishu', 'Yashwant', 'Abhishek']
# Assigning other name at the index value 1
my_list[1] = 'Yogesh'
print(my_list)
print('-'*20)
# What interpreter does internally
my_list.__setitem__(2, 'Rishu')
print(my_list)
```
When we run the above code, we'll get the following output.
```bash
['Sachin', 'Yogesh', 'Yashwant', 'Abhishek']
--------------------
['Sachin', 'Yogesh', 'Rishu', 'Abhishek']
```
### Syntax
`__setitem__(self, key, value)`
The `__setitem__` assigns a value to the key. If we call `self[key] = value`, then it will be evaluated as `self.__setitem__(key, value)`.
`self` - object or instance of the class
`key` - the item that will be replaced
`value` - `key` will be replaced by this value
### \_\_setitem\_\_ in Python classes
The following example demonstrates the implementation of the `__setitem__` method in a Python class.
```python
# Creating a class
class Roles:
# Defining __init__ method
def __init__(self, role, name):
# Creating a dictionary with key-value pair
self.detail = {
'name': name,
'role': role
}
# Defining __getitem__ method
def __getitem__(self, key):
return self.detail[key]
# Function to get the role and name
def getrole(self):
return self.__getitem__('role'), self.__getitem__('name')
# Defining __setitem__ method
def __setitem__(self, key, value):
self.detail[key] = value
# Function to set the role and name
def setrole(self, role, name):
print(f'{role} role has been assigned to {name}.')
return self.__setitem__('role', role), self.__setitem__('name', name)
# Instantiating the class with required args
data = Roles('Python dev', 'Sachin')
# Printing the role with name
print(data.getrole())
# Setting the role for other guys
data.setrole('C++ dev', 'Rishu')
# Printing the assigned role with name
print(data.getrole())
# Setting the role for other guys
data.setrole('PHP dev', 'Yashwant')
# Printing the assigned role with name
print(data.getrole())
```
We created a `Roles` class and a `__init__` function, passing the `role` and `name` parameters and storing them in a dictionary.
Then we defined the `__getitem__` method, which returns the key's value, and the `getrole()` function, which accesses the value passed to the key `name` and `role`.
Similarly, we defined the `__setitem__` method, which assigns a value to the key, and we created the `setrole()` function, which assigns the specified values to the key `role` and `name`.
The class `Roles('Python dev,' 'Sachin')` was then instantiated with required arguments and stored inside the `data` object. We printed the `getrole()` function to get the **role** and **name**, then we called the `setrole()` function twice, passing it the various **roles** and **names**, and printing the `getrole()` function for each `setrole()` function we defined.
```bash
('Python dev', 'Sachin')
C++ dev role has been assigned to Rishu.
('C++ dev', 'Rishu')
PHP dev role has been assigned to Yashwant.
('PHP dev', 'Yashwant')
```
We got the values passed as an argument to the class but after it, we set the different roles and names and got the output we expected.
## \_\_delitem\_\_
The `__delitem__` method deletes the items in the list, dictionary, or array. The item can also be deleted using the `del` keyword.
```python
# List of names
my_list = ['Sachin', 'Rishu', 'Yashwant', 'Abhishek']
# Deleting the first item of the list
del my_list[0]
print(my_list)
# Deleting the item using __delitem__
my_list.__delitem__(1)
print(my_list)
----------
['Rishu', 'Yashwant', 'Abhishek']
['Rishu', 'Abhishek']
```
In the above code, we specified the `del` keyword and then specified the index number of the item to be deleted from `my_list`.
So, when we call `del my_list[0]` which is equivalent to `del self[key]`, Python will call `my_list.__delitem__(0)` which is equivalent to `self.__delitem__(key)`.
### **\_\_**delitem\_\_ in Python class
```python
class Friends:
def __init__(self, name1, name2, name3, name4):
self.n = {
'name1': name1,
'name2': name2,
'name3': name3,
'name4': name4
}
# Function for deleting the entry
def delname(self, key):
self.n.__delitem__(key)
# Function for adding/modifying the entry
def setname(self, key, value):
self.n[key] = value
friend = Friends('Sachin', 'Rishu', 'Yashwant', 'Abhishek')
print(friend.n, "\n")
# Deleting an entry
friend.delname('name3')
print('After deleting the name3 entry')
print(friend.n, "\n")
# Modifying an entry
friend.setname('name2', 'Yogesh')
print('name2 entry modified')
print(friend.n, "\n")
# Deleting an entry
friend.delname('name2')
print('After deleting the name2 entry')
print(friend.n)
```
We defined the `delname` function in the preceding code, which takes a `key` and deletes that entry from the dictionary created inside the `__init__` function, as well as the `setname` function, which modifies/adds the entry to the dictionary.
Then we instantiated the `Friends` class, passed in the necessary arguments, and stored them in an instance called `friends`.
Then we used the `delname` function to remove an entry with the key `name3` before printing the updated dictionary. In the following block, we modified the entry with the key `name2` to demonstrate the functionality of `setname` function and printed the modified dictionary, then we deleted the entry with the key `name2` and printed the updated dictionary.
```bash
{'name1': 'Sachin', 'name2': 'Rishu', 'name3': 'Yashwant', 'name4': 'Abhishek'}
After deleting the name3 entry
{'name1': 'Sachin', 'name2': 'Rishu', 'name4': 'Abhishek'}
name2 entry modified
{'name1': 'Sachin', 'name2': 'Yogesh', 'name4': 'Abhishek'}
After deleting the name2 entry
{'name1': 'Sachin', 'name4': 'Abhishek'}
```
## Conclusion
We learned about the `__getitem__`, `__setitem__`, and `__delitem__` methods in this article. We can compare `__getitem__` to a getter function because it retrieves the value of the attribute, `__setitem__` to a setter function because it sets the value of the attribute, and `__delitem__` to a deleter function because it deletes the item.
We implemented these methods within Python classes in order to better understand how they work.
We've seen code examples that show what Python does internally when we access, set, and delete values.

A helper container (the sidecar) is deployed alongside a main app container within the same pod. This pattern allows each container to focus on a single aspect of the overall functionality, improving the maintainability and scalability of apps deployed in Kubernetes environments. From gathering metrics to connecting to data sources (a la [Dapr](https://dapr.io/)), sidecars have found a notable place in the cloud-native developer’s toolbox. Sidecars are designed to run alongside your apps continuously and do not scale down to zero. Wouldn't it be great if they did? In this article, we introduce scaling sidecars to zero in Kubernetes.
## Zero Cost Sidecars in Kubernetes
WebAssembly (Wasm) and containers will peacefully co-exist and be complementary technologies. While containers offer an efficient way to package entire apps with dependencies, Wasm provides a lightweight, secure, and fast-executing environment that can help scale apps, making serverless Wasm workloads the ideal partner for long-running container apps. In fact, Solomon Hykes (founder of Docker) said this five years ago
Before we explore one such example of Wasm and containers, a word about efficiency.
## Maximizing Efficiency With the Sidecar Pattern
A common criticism of the sidecar pattern is its inefficiency. The underlying problem with sidecars is that the sidecar containers must remain operational throughout the lifespan of the main app, leading to potential resource wastage. Consider an app with three sidecars (so four total containers). A typical deployment sets the replica count to 3. So deploying a single app results in 12 long-running containers — three replicas of each of the 4 containers. All 12 of those processes consume CPU and memory all the time.
With [SpinKube](https://www.spinkube.dev/), there’s a cool way to enjoy all of the benefits of a sidecar without the resource consumption.
Wasm apps written using [Spin](https://github.com/fermyon/spin) apps follow a design pattern called serverless functions in which the app is started once when a request comes in. The app handles the request and then shuts down. If four requests come in simultaneously, then four copies of the app are started. When zero requests come in, no copies of the app are running. They are, in this sense, “zero cost”.
Spin apps, based on their Wasm underpinnings, are also lightweight. They cold-start in under a millisecond (as opposed to the dozens of seconds it takes a container to start up). They consume fewer resources at runtime, using around 2-5M of memory and minuscule amounts of CPU. And because they only run while processing a request, most live no more than a few hundred milliseconds.
Spin apps are a great candidate technology for implementing sidecars. And SpinKube makes it possible.
## Spin Apps as Sidecars
First, talking about how an app and its sidecars are connected is good. We’ll take a trivial scenario from Dapr. In that ecosystem, a main process uses HTTP or gRPC to communicate with its sidecars. You can almost think about it as the microservice architecture applied to a Kubernetes pod. Say we have an example with one app querying a sidecar service for an HTTP response. In this scenario, the main app periodically needs to perform an HTTP request to the other service. Both are long-running servers, but the main app creates an HTTP client that talks to the sidecar’s HTTP server. That sidecar HTTP server does its internal routing and executes the correct business logic to handle the request.
With a Spin app, there is no reason for the sidecar to need a long-running process. After all, it only needs to handle requests from one other client: the main app. This is a perfect candidate for a Spin app.
When this app is deployed, the main app (in a container) is run in the container runtime, and it executes as a server, always on, always listening.
The Spin app sidecar is deployed in the same pod as the container app, but **it is scheduled onto a Spin runtime instead of a container runtime.**
The Spin app is deployed, but it is not (properly speaking) running.
When a new request comes into the main app, its HTTP server receives and handles the request. That main app contacts the sidecar at some point over a local HTTP request. When the request to open the network connection happens, the containerd Spin shim (the thing in containerd that handles Spin app invocation) starts a new instance of the Spin app to handle the request object it received from the main app. The new instance of the Spin app then runs to completion, returns a response object, and shuts down.
The important thing to note here is that the Spin app *only runs* when handling the request. After that, all the resources it uses, including CPU and memory, are freed up again.
Running 4 or 12 of these sidecars per pod can be done efficiently. In fact, it’s preferable to run all of those sidecars in the same Spin instance, meaning they share their resource allocations even more efficiently. In theory, one could run over 1,000 sidecars per main app, but it’s unlikely that there’s a practical use case where this is the best design.
### Creating Our Spin App Sidecar
We, begin by using the Spin template - in this case the (Rust HTTP template)[https://github.com/fermyon/spin-rust-sdk] to get us started:
```bash
cd $HOME
spin new -t http-rust --accept-defaults spin-app-sidecar
cd spin-app-sidecar
```
We then add some business logic to the sidecar. In this case, telling the main-container-server app what the current time is:
```rust
use spin_sdk::http::{IntoResponse, Request, Response};
use spin_sdk::http_component;
use chrono::Local;
/// A simple Spin HTTP component.
#[http_component]
fn handle_spin_app_sidecar(_req: Request) -> anyhow::Result<impl IntoResponse> {
Ok(Response::builder()
.status(200)
.header("content-type", "text/plain")
.body(Local::now().format("%Y-%m-%d %H:%M:%S").to_string())
.build())
}
```
As you can see above, we are using the `chrono` library to obtain and help with formatting the time. To resolve dependencies, run the following command:
```bash
cargo add chrono
```
Our spin-app-sidecar app is now ready to build and push.
We will now use a [GitHub Personal Access Token](https://github.com/settings/tokens/new) (via the `GH_PAT` and `GH_USER` variables in our CLI) to push the app to a registry. First, we generate [a GitHub Personal Access Token](https://github.com/settings/tokens/new) and set `write:packages` in your our GitHub user interface. We then set the `GH_PAT` and `GH_USER` variables in our CLI and then push the app to a registry:
```bash
# Store PAT and GitHub username as environment variables
export GH_PAT=YOUR_TOKEN
export GH_USER=YOUR_GITHUB_USERNAME
# Authenticate spin CLI with GHCR
echo $GH_PAT | spin registry login ghcr.io -u $GH_USER --password-stdin
# Push container server app to the registry
spin registry push --build ghcr.io/$GH_USER/dapr-integration/spin-app-sidecar:1.0.1
```
We can now use `spin kube scaffold` to generate a `.yaml`file based on the deployed app:
```bash
spin kube scaffold --from ghcr.io/$GH_USER/spin-app-sidecar:1.0.1 \
--out spin-app-sidecar.yaml
```
The above command will create a `spin-app-sidecar.yaml` file with the following contents (note, we have replaced the static username with the `$GH_USER` variable here for your convenience):
```bash
apiVersion: core.spinoperator.dev/v1alpha1
kind: SpinApp
metadata:
name: spin-app-sidecar
spec:
image: "ghcr.io/$GH_USER/spin-app-sidecar:1.0.1"
executor: containerd-shim-spin
replicas: 2
```
Deploy the app using the `.yaml` file:
```bash
kubectl apply -f spin-app-sidecar.yaml
```
## Scheduler Overhead
So far we’ve seen why Spin apps make excellent sidecars. We’ve stayed at a fairly high level. But we should be aware of what happens under the hood. While the apps themselves take no CPU or memory, containerd has to do a little more work, and it does this using a low-level Spin shim.
The Spin shim listens for inbound requests for a Spin app and then starts the relevant serverless function to handle the request. Of course, this requires a small amount of memory deep in the Kubernetes stack, but it is still lighter than the work containerd must do to start a container.
> The situation is different in [Fermyon Platform for Kubernetes](https://www.fermyon.com/platform), in which Wasm is not scheduled through containerd, and one process per node handles thousands upon thousands of Wasm apps.
But again, even up to a thousand Spin sidecars can be scheduled using fewer resources than one container-based sidecar.
## Running More Apps in Your Cluster
Thanks to SpinKube’s ability to run Spin apps side-by-side with containers, Spin apps can be used in exciting ways. Here, we’ve taken a fresh look at the sidecar pattern that is popular with service meshes and distributed API services like Dapr. And what we’ve seen is that Spin apps make an excellent alternative to older containerized sidecars. Spin apps are faster and more efficient, meaning you can run more apps in your cluster. This translates not only to increased density but also to smaller clusters and saved money.
## Local Service Chaining
Spin's [local service chaining](https://developer.fermyon.com/spin/v2/http-outbound#local-service-chaining) functionality allows developers to write applications as a network of chained microservices, whereby a "self-request" (an internal component request) can be passed in memory without ever leaving the Spin host process. Although it may limit how deployments can be arranged, local service chaining is highly efficient, depending on the nature of the microservices. It's important to highlight this as a viable strategy for enhancing the integration of helper workloads alongside long-running apps.
## Conclusion 🎉
These new approaches to orchestration can minimize CPU and memory usage, ultimately allowing for higher app density per cluster and significant cost savings. In addition, more efficient operations and reduced startup times equate to faster machine-to-machine communication and improved end-user experience.

If you have, you've used content modeling without even realizing it. In The Sims, you create characters, build houses, and define relationships. Each of these elements has its attributes and rules. Knowing those rules and some hacks (motherlode is my fav) you can build a house or even a whole city to suit your needs and wishes.
Isn’t that just beautiful? 😍
So what would you do if I said to you that the Sims concept applies to content modeling, which involves defining and structuring various content types, attributes, and relationships to ensure your content is organized, reusable, and scalable?
So let’s see what it takes to start building your website efficiently as a house in the Sims. I will try to cover all the basics and, who knows, maybe some hacks.
## What is Content modeling (and all basics)
Instead of the definition, I’ll start with an example to help you understand content modeling. Take a look at your website, what do you see? There are a lot of different content formats, right? Let me guess:
- Landing pages
- Blog posts
- Gallery
- Home page
- Career page
- About us (and so on..)
All of these are content types and consist of a combination of individual content attributes. ****Some examples of content attributes include:
- Text fields
- Photos
- Videos
- Contact form
- FAQs
- Call to action
Defining those types and attributes, as well as establishing relationships and rules between them, is actually content modeling.
Ok, now you are ready for a definition too: Content modeling is the process of identifying and organizing the different types of content and their attributes within a system. It involves breaking down content into distinct, manageable components, making it easier to structure, compare, and connect information consistently across a platform or project.
### Why is content modeling important?
Content modeling influences different teams in an organization. It helps clarify requirements and fosters collaboration among designers, developers creating the CMS, and content creators.
**For designers:** The content model ensures that page designs accommodate all content types on the site and guide what text and media will be available. Along with supporting the design's content, layout, and functionality, it must also be compatible with the actual web structure.
**For developers:** The content model helps developers understand content needs and requirements as they configure the CMS. With various CMS types, achieving the same effect can differ. If the content model indicates something not easily done by a given CMS, developers can adjust their approach to achieve the desired result compatiblely. Developers need a detailed content model; if the content strategist doesn’t provide it, developers will interpret content needs and create details themselves.
**For content authors:** The content model provides guidelines on what content to create and how to enter it into the CMS. Although they are usually not involved in the content modeling process, it's important to keep them in mind, since they will be working with the CMS daily. To make the system user-friendly for them, keep the model intuitive, and consistent, and minimize redundant activities. Depending on how the system is set up, the content model can either streamline or complicate their work.
## Different approaches to content modeling
Content modeling can take various forms depending on the specific needs and structure of the project. It is possible to create structured content using these common content model examples:
### Hierarchical model
In a hierarchical content model, content is organized in a tree structure, with parent-child relationships. This model is useful for websites or applications with clear categories and subcategories.
- **Example:** A company website with sections for "About Us," "Products," "Services," and "Contact." Each section may have subsections, such as "Products" containing "Electronics," "Furniture," etc.
### Matrix model
The matrix content model organizes content types and their attributes in a grid format. This model highlights the relationships and intersections between different content types.
- **Example:** An e-commerce site where products are organized by categories (like clothing, electronics) and attributes (like size, color, price).
### Graph model
In a graph content model, content types are nodes, and the relationships between them are edges. This model is suitable for complex, interconnected content.
- **Example:** A social media platform where users, posts, comments, and likes are interconnected in various ways.
### Document model
The document content model treats each piece of content as a standalone document. This model is often used for content-heavy sites like blogs, news sites, or document repositories.
- **Example:** A news website where each article is an individual document with attributes like title, author, publication date, and content.
### Component-based model
In a component-based content model, content is broken down into reusable components or modules. This approach is common in systems that require consistent content presentation across different platforms.
- **Example:** A content management system for a large enterprise where headers, footers, and content blocks are reused across multiple pages and channels.
Learn more: [BCMS Widgets - Reusable structured content - everything you need to know](https://thebcms.com/blog/bcms-widgets-reusable-structured-content-tutorial)
### Attribute-based model
The attribute-based content model focuses on defining specific attributes for each content type. This model is useful for systems that need to filter or sort content based on attributes.
- **Example:** A real estate website where properties are listed with attributes like location, price, size, and number of bedrooms.
### Template model
In a template content model, predefined templates dictate the structure of content. This model ensures consistency in content presentation and is often used in CMS platforms.
- **Example:** A blogging platform where each post follows a template with fields for title, author, body text, tags, and publication date.
### Task-oriented model
The task-oriented content model organizes content around user tasks or goals. This model is user-centric and focuses on the user's needs and how content supports their tasks.
- **Example:** A customer support portal where content is organized around common user issues and tasks like troubleshooting, FAQs, and contact support.
### Relationship model
The relationship model emphasizes the connections between different pieces of content. It maps out how various content types relate to each other, which is particularly useful for content that needs to be interconnected.
- **Example:** A university website where courses are linked to departments, professors, and related resources. A course might have relationships with a syllabus, reading materials, and assessments.
### Assembly model
The assembly model focuses on how different content components can be assembled to create a complete piece of content. It often involves breaking down content into smaller, reusable modules or components that can be dynamically assembled as needed.
- **Example:** A marketing website where various content blocks like headers, testimonials, product descriptions, and CTAs are assembled into different landing pages.
Each model has its advantages and is suitable for different scenarios. The choice of content model depends on the complexity of the content, the relationships between different content types, and the specific requirements of the project.
## How to create a content model
Creating a content model involves a systematic approach to defining and organizing the types and attributes of content you will manage. Here’s a step-by-step guide:
### Step 1: Identify content elements
Determine the distinct elements of content that will be part of your project. Each content element represents the different kinds of information you will manage.
Let's take an e-commerce website as an example:
- Products
- Categories
- Reviews
- Users
- Blog
### Step 2: Define attributes
Identify the attributes or fields ( specific pieces of information) that each content element will contain.
- **Example of products:**
- Name
- Description
- Price
- Images
- Category
- Reviews
### Step 3: Establish relationships
Determine how different content pieces relate to each other.
### One-to-one relationship
Example: Each **User Profile** has one unique **Account Settings** entry.
Relationship: Each user profile is linked to a unique account settings entry.
### One-to-many relationship
One instance of a content type can be related to multiple instances of another content type.
Example: A single **Category** can contain multiple **Products**.
Relationship: One category, such as "Electronics," can contain many products like "Smartphones," "Laptop," and "Headphones."
### Many-to-one relationship
Multiple instances of one content type are related to a single instance of another content type.
Example: Multiple **Reviews** can be associated with one **Product**.
Relationship: Many reviews, such as user reviews for "Smartphones," are associated with one product.
### Many-to-many relationship
Instances of one content type can relate to multiple instances of another content type, and vice versa.
Example: A **Product** can belong to multiple **Categories**, and each **Category** can contain multiple **Products**.
Relationship: A "Smartphone" product might belong to both the "Electronics" and "Mobile Devices" categories. Conversely, the "Electronics" category can contain products like "Smartphones," "Laptop," and "Camera."
### Step 4: Create content model templates
Develop templates for each content type to ensure consistency. These templates should include all defined attributes and provide a structure for content creation.
Product Template:
- Title
- Text area for Description
- Field for Price
- Upload section for Images
- Dropdown for Category

### Step 5: Develop a content schema

## TL;DR
When I started making open source libraries, I didn't know much about unit testing in terms of writing the tests, and setting up the environment. There was a strong voice that told me to write unit tests for my open source libraries because if one day it gets big (hopefully) it wouldn't be efficient to test every functionality manually.
Acknowledging the benefits of unit testing, I jumped right in to the one and only [Jest](https://jestjs.io/). Honestly it overwhelms me a little bit too much when I read the docs and there are a lot of things going on in there. But I didn't lose spirit by just reading a docs, otherwise I wouldn't call myself a learner 😅
## The challenges
Because it was the first time I'm learning unit testing using Jest, I'm confused on how to set things up and running in my project. Most of my projects are using typescript + monorepo structure and it requires a specific config to make it running. Without further a do, let's dive right into it.
## Setting up
In this section, we'll go through the steps on how to configure Jest in Typescript Monorepo project so please follow along and read the steps carefully.
### Installation
First of all, we have to install a few packages as devDependencies especially if we are using typescript, there are extra packages that we must install.
```bash
$ npm i -D jest @types/jest ts-jest ts-node typescript
```
- **jest:** Is the tool for writing unit tests and run the tests
- **@types/jest:** Contains type definitions for jest
- **ts-jest:** A Jest transformer that allows us to use Jest for testing TypeScript code.
- **ts-node:** Allows us to run TypeScript code directly in Node.js without needing to precompile it to JavaScript
- **typescript:** You know what it is
After installing those packages, you can check your `package.json` to see if they are listed in `devDependencies`.
### Jest config
Let's create a `jest.config.ts` in the root of our project and write this
```ts
import type { Config } from "@jest/types";
const config: Config.InitialOptions = {
verbose: true,
preset: "ts-jest",
testEnvironment: "node",
transform: {
"^.+\\.(ts|tsx)$": "ts-jest",
},
projects: [
{
testPathIgnorePatterns: ["<rootDir>/node_modules/"],
preset: "ts-jest",
displayName: "my-package",
testMatch: ["<rootDir>/packages/my-package/__tests__/**/*.spec.ts"],
}
],
};
export default config;
```
Here is the explanation for each
- **verbose:** To show a verbose version of test reports.
- **preset:** A pre-configured set of settings and configurations for Jest.
- **testEnvironment:** The test environment that will be used for testing.
- **transform:** Specifies how different types of files should be processed before running the tests
- **projects:** Allows us to define multiple sets of configurations within a single Jest setup.
- **testPathIgnorePatterns:** An array of regular expression patterns that Jest uses to ignore test files
- **displayName:** A name to identify our project like an alias.
- **testMatch:** Specify the glob patterns that Jest uses to detect test files.
The configuration above assumes that your project structure look like this.
```
| - - packages
| - - - my-package
| - - - - __tests__
| - - - - - test.spec.ts
| - tsconfig.base.json
```
Inside you root `package.json`, you can create a script to run the test on a specific project.
```json
"script":{
"test:my-package": "jest --selectProjects=my-package"
}
```
### Writing tests
Now assuming that you have followed the configurations above, it's time for us to create our first test case. Inside the `__tests__` folder, create a file named `test.spec.ts` and write a dummy test to see if the configurations work perfectly.
```ts
describe("Test config", () => {
it("counts correctly", ()=>{
expect(1 + 1).toBe(2);
})
})
```
After writing the sample test, make sure you are in root directory and run the test script.
```bash
npm run test:my-package
```
## Conclusion
Unit testing using Jest is fun but can overwhelm new learners especially when configuring the Jest itself in order for it to work properly. The complexity even increases when we use different architecture such as monorepo. In spite of the complexity that Jest introduces, Jest is still a powerful testing tool that is used by many developers to test their projects, so it's worth it to learn Jest :).

1,885,858 | Balancing Life as a Remote Developer and a Dad: Tips from Newborn to Toddler Stage | Being a dad is one of the most rewarding experiences, but it also comes with its own set of... | 0 | 2024-06-12T14:30:35 | https://dev.to/danjiro/balancing-life-as-a-remote-developer-and-a-dad-tips-from-newborn-to-toddler-stage-43c1 | developer, dad, remote, developerdad | Being a dad is one of the most rewarding experiences, but it also comes with its own set of challenges, especially when you're trying to balance it with a demanding job as a developer. Working remotely adds a unique twist to this balancing act, providing both opportunities and obstacles. Here are some strategies that have helped me manage my time and sleep from the newborn stage through to the toddler years.
## Before thinking of being a dad, find a good wife!
Sounds funny, but having a supportive partner can make a world of difference. Sharing responsibilities and understanding each other’s schedules helps in creating a harmonious environment for both work and parenting.
## Establish a Flexible Schedule
### Early Morning Productivity
When you have a newborn, sleep schedules can be unpredictable. I've found that waking up early, before the baby, allows me to get some focused work done. Even an hour of uninterrupted time can be incredibly productive.
### Nap Time Hustle
As your child grows into the toddler stage, nap times can become more predictable. Use these windows of opportunity to tackle high-priority tasks. It’s amazing how much you can accomplish in a 1-2 hour nap window when you’re focused.
## Prioritize Your Tasks
### Use the Pomodoro Technique
The Pomodoro Technique, where you work for 25 minutes and then take a 5-minute break, can help maintain productivity during fragmented work periods. It’s especially useful when you need to attend to your child intermittently.
### Daily Task Lists
Create a daily list of tasks and prioritize them. I use tools like Jira, Trello or Asana to organize my work tasks and keep track of deadlines. Breaking down projects into smaller, manageable tasks makes it easier to make progress even with limited time.
## Communicate with Your Team
### Set Clear Boundaries
Working remotely requires clear communication with your team about your availability. Let them know your working hours and when you’ll be offline to take care of family responsibilities. Most teams are understanding and supportive if they know your situation.
### Regular Check-Ins
Schedule regular check-ins with your team to discuss progress and any issues. This ensures that you stay connected and aligned with team goals, even if you’re not always available for impromptu meetings.
## Optimize Your Work Environment
### Create a Dedicated Workspace
Having a dedicated workspace helps signal to your brain that it’s time to work, even if it’s just a corner of a room. Make sure it’s comfortable and free from distractions as much as possible. Plus, it's an investment!
### Noise-Canceling Headphones
Also invest in a good pair of noise-canceling headphones. They can be a lifesaver when you need to focus while your little one is playing or when there’s noise in the house.
## Take Care of Yourself
### Get Enough Sleep
Easier said than done, right? While you can’t control how much sleep you get with a newborn, try to nap when the baby naps. As your child grows, establish a bedtime routine to ensure both you and your child get enough rest.
### Exercise and Healthy Eating
Maintaining a healthy lifestyle helps boost your energy levels and productivity. Even short bursts of exercise, like a quick walk or a few minutes of stretching, can make a big difference. Eating nutritious meals also keeps your energy up throughout the day.
Take your child outside!
## Embrace the Chaos
Finally, remember that it’s okay if things don’t always go as planned. Flexibility is key. Some days will be more productive than others, and that’s perfectly fine. Enjoy the moments with your child and appreciate the unique opportunity to work remotely while being present for your family.

1,885,855 | Overview of EOS Economics Model | Overview of EOS Economics Model In this article, we'll delve into the key components of... | 0 | 2024-06-12T14:23:02 | https://dev.to/davidking/overview-of-eos-economics-model-1h9f | web3, eos, economics, blockchain | # Overview of EOS Economics Model
In this article, we'll delve into the key components of the EOS economics model and its implications for the ecosystem.
## Introduction
EOS is a blockchain platform that aims to provide a scalable and user-friendly environment for building and deploying dApps. At the core of EOS is its economics model, which governs how tokens are distributed, resources are allocated, and decisions are made within the network. By understanding the economics of EOS, participants can better navigate the ecosystem and contribute to its growth and sustainability.
## EOS’s Consensus Algorithm
Consensus algorithms form the backbone of blockchain networks, facilitating agreement among network participants on the validity of transactions and the state of the ledger. EOS's DPoS consensus algorithm is a novel approach to achieving consensus in a decentralized manner, offering scalability and high transaction throughput while maintaining network security.
### Advantages of DPoS
- Scalability: DPoS enables EOS to achieve high transaction throughput compared to traditional Proof of Work (PoW) or Proof of Stake (PoS) consensus algorithms. With a smaller set of block producers and faster block production times, EOS can process a large number of transactions per second.
- Efficiency: The election of block producers through voting ensures that only reputable and competent entities are entrusted with the responsibility of maintaining the network. This leads to more efficient block validation and faster consensus.
- Governance: DPoS facilitates transparent and decentralized governance within the EOS ecosystem. Token holders have the power to vote for block producers and participate in decision-making processes regarding network upgrades and protocol changes.
- ## Token Distribution
The initial distribution of EOS tokens was conducted through a year-long ICO (Initial Coin Offering), during which 1 billion EOS tokens were made available for purchase. The ICO raised a record-breaking amount, resulting in a diverse and widespread distribution of tokens among investors. Additionally, EOS employs a continuous token inflation model to incentivize block producers and fund network development.
> An image showing the distribution of EOS tokens during the ICO phase.
## Resource Allocation
EOS utilizes a unique resource allocation model to ensure that users have access to the resources they need to interact with the blockchain. This includes RAM allocation for storing data, CPU and network bandwidth for executing transactions, and stake-based voting for participating in network governance. Users can stake their EOS tokens to access resources or lease them from other token holders.
## Transaction Fees and Block Rewards
Transaction fees on the EOS network are minimal and primarily serve as a spam prevention mechanism rather than a source of revenue for block producers. Instead, block producers are rewarded with newly minted EOS tokens for validating transactions and producing blocks. The distribution of block rewards is designed to incentivize active participation in the network and maintain its security and integrity.
## Governance and Referendum
EOS employs a delegated proof-of-stake (DPoS) consensus mechanism, where token holders vote to elect a set of block producers who are responsible for validating transactions and maintaining the network. Token holders also have the power to propose and vote on referendums that govern various aspects of the EOS ecosystem, including protocol upgrades, resource allocation, and community initiatives.
## Economic Sustainability
Ensuring the long-term sustainability of the EOS network is paramount to its success. The economics model of EOS is designed to incentivize developers to build and maintain dApps on the platform, users to engage with these dApps, and stakeholders to actively participate in network governance. However, achieving economic sustainability requires ongoing collaboration, innovation, and adaptation to changing market dynamics.
## Comparison with Other Blockchain Economics Models
Compared to other blockchain platforms like Ethereum, EOS offers distinct advantages in terms of scalability, resource management, and governance. While Ethereum relies on gas fees to prioritize transactions and compensate miners, EOS provides users with predictable resource costs and minimal transaction fees. Additionally, the delegated governance model of EOS enables more efficient decision-making and protocol upgrades.
## Conclusion
The economics model of EOS plays a crucial role in shaping the dynamics of the platform and its ecosystem. By understanding how tokens are distributed, resources are allocated, and decisions are made within the network, participants can effectively navigate the EOS ecosystem and contribute to its growth and sustainability. As EOS continues to evolve, its economics model will play an increasingly important role in driving innovation and adoption within the blockchain industry. | davidking |

1,885,851 | Overview of Blockchain Consensus Algorithms | In this article, we'll delve into various consensus algorithms commonly used in blockchain networks,... | 0 | 2024-06-12T14:08:48 | https://dev.to/davidking/overview-of-blockchain-consensus-algorithms-564i | web3, blockchain, tutorial | In this article, we'll delve into various consensus algorithms commonly used in blockchain networks, exploring their characteristics, advantages, and limitations.
## Intro
Blockchain consensus algorithms are protocols that enable nodes in a distributed network to agree on the state of the blockchain. Consensus is achieved through a series of rules and mechanisms that govern how transactions are validated and added to the blockchain.
## Proof of Work (PoW)
Proof of Work is perhaps the most well-known consensus algorithm, famously used by Bitcoin. In PoW, miners compete to solve complex mathematical puzzles to validate transactions and create new blocks. The first miner to solve the puzzle gets to add the block to the blockchain and is rewarded with cryptocurrency.
PoW ensures network security through computational power, but it also consumes a significant amount of energy. Examples of blockchains utilizing PoW include Bitcoin and Ethereum (although Ethereum is transitioning to Proof of Stake).
> An image showing miners engaged in solving cryptographic puzzles to validate transactions and create new blocks.
## Proof of Stake (PoS)
Proof of Stake is an alternative consensus algorithm where validators are chosen to create new blocks based on the amount of cryptocurrency they hold and are willing to "stake" as collateral. In PoS, validators are incentivized to act honestly because they have a financial stake in the network.
PoS is more energy-efficient compared to PoW and encourages coin holders to participate in network maintenance. Examples of blockchains utilizing PoS include Cardano and Tezos.
## Delegated Proof of Stake (DPoS)
Delegated Proof of Stake is a variation of PoS where coin holders vote to elect a set number of delegates who are responsible for validating transactions and creating new blocks. DPoS aims to improve scalability and efficiency by delegating consensus to a smaller group of trusted nodes.
EOS and TRON are prominent examples of blockchains utilizing DPoS.
## Practical Byzantine Fault Tolerance (PBFT)
Practical Byzantine Fault Tolerance is a consensus algorithm designed to achieve consensus in a distributed system despite the presence of malicious nodes or communication failures. PBFT requires a predetermined number of nodes to agree on the validity of transactions before they are added to the blockchain.
Hyperledger Fabric is an example of a blockchain platform that utilizes PBFT to achieve consensus.
## Proof of Authority (PoA)
Proof of Authority is a consensus algorithm where validators are identified and authorized to create new blocks based on their reputation or identity. Validators are typically known and trusted entities, which reduces the risk of malicious activity.
PoA is commonly used in private or consortium blockchains where trust among participants is high. Examples include Quorum and Kovan Ethereum testnet.
## Comparison of Consensus Algorithms
Each consensus algorithm has its own set of advantages and limitations. Factors such as performance, security, energy consumption, and scalability vary depending on the algorithm used. It's essential to consider these factors when designing or choosing a blockchain network.
## Emerging Trends and Future Directions
Hybrid consensus models, combining elements of multiple algorithms, are gaining traction as blockchain technology evolves. Research and development efforts continue to explore novel consensus mechanisms that address the shortcomings of existing algorithms and pave the way for greater scalability, security, and efficiency.
## Conclusion
As the technology continues to evolve, so too will the consensus algorithms that underpin it, shaping the future of decentralized finance, governance, and beyond. | davidking |

June 12 marks the World Day Against Child Labour, a day dedicated to raising awareness and fostering global efforts to eliminate child labor. This year’s theme, “Exclusion and Sustainability – The Example of Child Labor,” highlights the importance of sustainable practices in eradicating child labor.
The Scourge of Child Labor:
Child labor affects millions of children worldwide, depriving them of education, health, and a safe childhood. These children work in hazardous conditions, often for little or no pay, undermining their potential and perpetuating cycles of poverty.
Inrate's Perspective:
Inrate, a leader in ESG (Environmental, Social, and Governance) data solutions, emphasizes that sustainable business practices are key to combating child labor. Their recent article, [Exclusion and Sustainability – The Example of Child Labor](https://inrate.com/news/exclusion-and-sustainability-the-example-of-child-labor/), explores how responsible investing and corporate governance can lead to better outcomes for children globally.
Sustainability and Corporate Responsibility:
Sustainability involves not just environmental stewardship but also social equity. Companies must adopt policies that exclude child labor from their supply chains. By doing so, they not only comply with regulations but also build a reputation for ethical practices.
The Role of Investors:
Investors play a crucial role in this fight. By prioritizing ESG criteria, they can influence companies to adopt fair labor practices. Investments in businesses that ensure ethical supply chains contribute to the global effort against child labor.
Conclusion:
On this World Day Against Child Labour, let’s reaffirm our commitment to building a sustainable future where every child is free from exploitation and able to realize their full potential. Together, we can create a world where sustainability and child welfare go hand in hand.

1,885,841 | Unlocking the Secrets to Optimal Betta Pellets Fish Nutrition | Introduction: Understanding the Importance of Betta Pellets In the realm of aquatic companionship,... | 0 | 2024-06-12T13:53:10 | https://dev.to/saad_rajpoot_0c0b85c2ab74/unlocking-the-secrets-to-optimal-betta-pellets-fish-nutrition-1d39 | **Introduction: Understanding the Importance of Betta Pellets**
In the realm of aquatic companionship, few creatures captivate quite like the majestic Betta fish. With their vibrant colors and elegant fins, Betta fish have secured their place as beloved pets in countless households worldwide. Yet, behind their beauty lies a delicate balance of care, and nutrition stands as a cornerstone of their well-being.
**The Significance of Proper Nutrition for Betta Fish**
**https://healthystyletrends.com/betta-pellets/**, often hailed as the go-to staple food for these exquisite creatures, plays a pivotal role in maintaining their health and vitality. However, not all pellets are created equal. In our pursuit of ensuring the optimal diet for Betta fish, it becomes imperative to delve deeper into the intricacies of their nutritional requirements.
**Unveiling the Nutritional Needs of Betta Fish**
**Protein: The Building Blocks of Health**
At the core of Betta fish nutrition lies the necessity for protein. These carnivorous creatures thrive on a diet rich in high-quality proteins, which serve as the foundation for muscle development and overall vitality. When selecting Betta pellets, prioritize those with a high protein content derived from sources such as fish meal or shrimp.
**Essential Fatty Acids: Promoting Optimal Growth and Development**
In addition to protein, Betta fish require a steady supply of essential fatty acids to support various physiological functions. Omega-3 and Omega-6 fatty acids, found abundantly in quality Betta pellets, contribute to vibrant colors, enhanced immune response, and reproductive health. Look for pellets fortified with fish oil or other marine-derived sources to meet this crucial dietary need.
**Vitamins and Minerals: Enhancing Overall Well-Being**
A well-rounded Betta pellet should also provide a spectrum of vitamins and minerals essential for maintaining optimal health. Vitamins such as A, C, and E bolster the immune system, while minerals like calcium and phosphorus support bone density and metabolic processes. Seek out pellets formulated with a diverse array of nutrients to ensure comprehensive nutritional support for your Betta fish.
**Navigating the Landscape of Betta Pellets: Tips for Selection
Quality Over Quantity: Prioritizing Nutrient Density**
When perusing the aisles for Betta pellets, resist the temptation to prioritize quantity over quality. Opt for pellets crafted from premium ingredients, as these are more likely to deliver the essential nutrients your Betta fish require for thriving health. While budget-friendly options may seem appealing, investing in high-quality pellets ultimately pays dividends in the form of vibrant colors and robust vitality.
**Consider Pellet Size: Tailoring to Individual Needs**
Betta fish, like humans, come in a variety of shapes and sizes. As such, it's crucial to consider the size of the pellets you offer your aquatic companions. Larger pellets may be suitable for adult Betta fish, while smaller varieties are better suited to juveniles or those with smaller mouths. By selecting pellets tailored to your Betta's size, you can ensure optimal digestion and prevent the risk of overfeeding.
**Watch for Additives: Minimizing Potential Harm**
In the pursuit of optimal nutrition, it's essential to scrutinize the ingredients list of Betta pellets for any additives or artificial preservatives. While these substances may prolong shelf life, they can pose risks to your Betta fish's health in the long run. Opt for pellets free from unnecessary additives, and prioritize those made with natural ingredients to safeguard the well-being of your aquatic companions.
**Conclusion: Elevating Betta Fish Care Through Superior Nutrition**
In essence, the journey towards providing optimal nutrition for Betta fish begins with the humble pellet. By selecting pellets rich in protein, essential fatty acids, vitamins, and minerals, you can empower your Betta fish to thrive in their aquatic habitat. Remember, the key lies in prioritizing quality, tailoring pellet size to individual needs, and minimizing the presence of harmful additives. With the right approach to Betta fish nutrition, you can unlock a world of vibrant colors, robust vitality, and boundless joy in your aquatic companions. | saad_rajpoot_0c0b85c2ab74 | |

1,885,660 | How To Dockerize Remix Apps 💿🐳 | Dockerizing your Remix app is straightforward and makes your app independent of hosting providers!... | 0 | 2024-06-12T13:50:43 | https://dev.to/code42cate/how-to-dockerize-remix-apps-2ack | docker, devops, beginners, webdev | Dockerizing your Remix app is straightforward and makes your app independent of hosting providers! Let's get to it and build a production ready Dockerfile! 🤘🗿
## Basic Dockerfile
To get started, let's create a basic Dockerfile for our Remix app:
```Dockerfile
FROM node:21-bullseye-slim
WORKDIR /myapp
ADD . .
RUN npm install
RUN npm run build
CMD ["npm", "start"]
```
Make sure to change the command to match your start script if it differs from npm start. You can then build it like this:
```bash
docker build -t remix-minimal .
```
## Improvements
As always with Docker, you can improve your Docker image in a few easy ways. Let's look at the two most obvious ways: copying only what you need (improving caching!) and multi-stage builds (improving the image size!) 🚀
### Copying Only What You Need
A lot of the time your docker build takes comes from expensive I/O operations or the inability to cache single steps of your build process.
#### .dockerignore 🤷
Firstly, create a .dockerignore file with everything that you do not want in your Docker image. This usually includes stuff like your node_modules, compiled files, or documentation. Simply write the folder names that you want to be ignored in a file, or copy an existing one.
```plain
node_modules
README.md
LICENSE
.env
```
### Separate Copy Steps
If you are actively developing your app and you need to constantly rebuild your Docker Image, chances are that your code changes a lot more than your dependencies. You can profit from that fact by separating the install and build steps. Docker will then only re-install your dependencies if they actually changed! 🥳
```Dockerfile
FROM node:21-bullseye-slim
WORKDIR /myapp
### Copy the lock and package file
ADD package.json .npmrc ./
### Install dependencies
RUN npm install --include=dev
### Copy your source code
### If only files in the src folder changed, this is the only step that gets executed!
ADD . .
RUN npm run build && npm prune --omit=dev
CMD ["npm", "start"]
```
### Multi-Stage Builds
If you want to be a bit fancier or you need a smaller Docker image, you can also use multi-stage builds. This reduces the final image size by only including necessary runtime dependencies.
We'll take the Dockerfile from the previous step as the template but extend it to use multi-stage builds. We'll build the app in one stage and use a smaller base image for the final stage.
```Dockerfile
# base node image
FROM node:21-bullseye-slim as base
# set for base and all layer that inherit from it
ENV NODE_ENV production
# Install all node_modules, including dev dependencies
FROM base as deps
WORKDIR /myapp
ADD package.json .npmrc ./
RUN npm install --include=dev
# Setup production node_modules
FROM base as production-deps
WORKDIR /myapp
COPY --from=deps /myapp/node_modules /myapp/node_modules
ADD package.json .npmrc ./
RUN npm prune --omit=dev
# Build the app
FROM base as build
WORKDIR /myapp
COPY --from=deps /myapp/node_modules /myapp/node_modules
ADD . .
RUN npm run build
# Finally, build the production image with minimal footprint
FROM base
WORKDIR /myapp
COPY --from=production-deps /myapp/node_modules /myapp/node_modules
COPY --from=build /myapp/build /myapp/build
COPY --from=build /myapp/public /myapp/public
ADD . .
CMD ["npm", "start"]
```
## Credits
The Dockerfile is based on one of the [official Remix stacks](https://github.com/remix-run/blues-stack/blob/main/Dockerfile)!
## Next Steps
How was your experience developing and deploying your Remix app? I've really enjoyed it so far, although there is still a lot of work to do to make it truly great. I'd love to hear your opinions!

1,885,839 | Writing Rust Documentation | Writing effective documentation is crucial for any programming language, and Rust is no exception.... | 27,702 | 2024-06-12T13:49:30 | https://dev.to/gritmax/writing-rust-documentation-5hn5 | rust, developer, beginners, tutorial | Writing effective documentation is crucial for any programming language, and Rust is no exception. Good documentation helps users understand how to use your code, what it does, and why it matters. In this guide, I'll walk you through the best practices for writing documentation in Rust, ensuring that your code is not only functional but also accessible and user-friendly.
## Introduction to Rust Documentation
Rust documentation is typically written using `rustdoc`, a tool that generates HTML documentation from comments in your source code. The primary goal of `rustdoc` is to make it easy for developers like you and me to document our code in a way that is both comprehensive and easy to understand.
### Why Documentation Matters
Documentation serves several key purposes:
1. **Communication**: It explains what your code does, how it works, and how to use it.
2. **Maintenance**: It helps future developers (including yourself) understand the codebase, making it easier to maintain and extend.
3. **Onboarding**: It aids new team members in getting up to speed with the project.
4. **Community**: It allows the broader community to use and contribute to your project.
## Writing Documentation in Rust
### Commenting Your Code
Rust uses three types of comments for documentation:
1. **Line comments**: Start with `//` and are used for short, single-line comments.
2. **Block comments**: Enclosed in `/* ... */` and can span multiple lines.
3. **Doc comments**: Start with `///` for item-level documentation or `//!` for module-level documentation.
#### Item-Level Documentation
Item-level documentation comments (`///`) are used to describe functions, structs, enums, traits, and other items. These comments should be placed directly above the item they describe.
{% embed https://gist.github.com/gritmaxuk/3c215427b7b1f552ae7fa9b1b9de7607 %}
In this example, the `add` function is documented with a brief description and an example of how to use it. The `# Examples` section is a common convention in Rust documentation, providing a clear and concise way to demonstrate usage.
#### Module-Level Documentation
Module-level documentation comments (`//!`) are used to describe the overall purpose and functionality of a module. These comments should be placed at the top of the module file.
{% embed https://gist.github.com/gritmaxuk/5b085c4cab08c9d83fecfcfaf40ba043 %}
Here, the module-level comment provides a high-level overview of the module's purpose, while the item-level comments describe the individual functions.
### Structuring Your Documentation
Good documentation is well-structured and easy to navigate. Here are some tips for structuring your Rust documentation:
1. **Use Sections**: Break your documentation into sections using headings. Common sections include `# Examples`, `# Panics`, `# Errors`, and `# Safety`.
2. **Provide Examples**: Examples are one of the most effective ways to demonstrate how to use your code. Include them wherever possible.
3. **Explain Edge Cases**: Document any edge cases or special conditions that users need to be aware of.
4. **Link to Related Items**: Use intra-doc links to connect related items within your documentation. This helps users navigate your documentation more easily.
#### Using Sections
Sections help organize your documentation and make it easier to read. Here are some common sections you might include:
- **Examples**: Show how to use the item.
- **Panics**: Describe any conditions under which the item might panic.
- **Errors**: Explain any errors that might be returned.
- **Safety**: For `unsafe` code, explain why it is safe to use.
{% embed https://gist.github.com/gritmaxuk/4a18ead577fb92ed41273f954e3b344e %}
In this example, the `divide` function documentation includes an `# Examples` section to show how to use the function and a `# Panics` section to describe a condition that will cause the function to panic.
#### Providing Examples
Examples are crucial for helping users understand how to use your code. They should be simple, clear, and demonstrate the most common use cases.
{% embed https://gist.github.com/gritmaxuk/3c829d1d5f5715ca6564511cca6f546c %}
This example shows how to calculate the factorial of a number, providing a clear and concise example of how to use the `factorial` function.
#### Explaining Edge Cases
Edge cases are situations that occur outside of normal operating conditions. Documenting these cases helps users understand how your code behaves in less common scenarios.
{% embed https://gist.github.com/gritmaxuk/0312b7a4fe4a26c62a9e35ff1de5286b %}
In this example, the `fibonacci` function documentation includes a `# Panics` section to explain that the function will panic if the input is too large.
#### Linking to Related Items
Intra-doc links allow you to create hyperlinks to other items within your documentation. This helps users navigate your documentation more easily.
{% embed https://gist.github.com/gritmaxuk/49aa865a3ffcc584a0d601302001b4c8 %}
In this example, the `add` and `subtract` functions link to each other using intra-doc links, making it easy for users to navigate between related items.
### Using the `#[doc]` Attribute
The `#[doc]` attribute in Rust provides additional flexibility for writing documentation. You can use it to add documentation to items in a more programmatic way. This attribute is particularly useful when you need to generate documentation dynamically or when you want to include documentation that isn't directly tied to a specific item.
#### Basic Usage
The `#[doc]` attribute can be used to add documentation to any item. Here's a simple example:
```rust
#[doc = "Adds two numbers together."]
fn add(a: i32, b: i32) -> i32 { a + b }
```
This is equivalent to using the `///` comment style but allows for more complex scenarios.
#### Including External Files
You can use the `#[doc]` attribute to include documentation from external files. This is useful if you have large blocks of documentation that you want to keep separate from your code.
```rust
#[doc = include_str!("docs/add_function.md")]
fn add(a: i32, b: i32) -> i32 { a + b }
```
In this example, the documentation for the `add` function is included from an external Markdown file.
#### Conditional Documentation
The `#[doc]` attribute can also be used to conditionally include documentation based on compile-time conditions. This is useful for documenting platform-specific behavior or features.
```rust
#[cfg(target_os = "windows")]
#[doc = "This function is only available on Windows."]
fn windows_only_function() { // Windows-specific code }
#[cfg(target_os = "linux")]
#[doc = "This function is only available on Linux."]
fn linux_only_function() { // Linux-specific code }
```
In this example, different documentation is included based on the target operating system.
### Best Practices for Writing Documentation
Here are some best practices to keep in mind when writing Rust documentation:
1. **Be Clear and Concise**: Write in a clear and concise manner. Avoid unnecessary jargon and keep sentences short and to the point.
2. **Use Proper Grammar and Spelling**: Ensure your documentation is free of grammatical and spelling errors. This helps maintain a professional appearance.
3. **Be Consistent**: Use consistent terminology and formatting throughout your documentation. This makes it easier for users to understand and follow.
4. **Keep It Up to Date**: Regularly update your documentation to reflect changes in your code. Outdated documentation can be more harmful than no documentation at all.
5. **Use Code Examples**: Include code examples wherever possible. They are one of the most effective ways to demonstrate how to use your code.
6. **Document All Public Items**: Ensure that all public items (functions, structs, enums, etc.) are documented. This helps users understand how to use your library or application.
### Example of Comprehensive Documentation
Let's put it all together with a comprehensive example:
{% embed https://gist.github.com/gritmaxuk/9bc75ce310a1802c5f2641d6c742d849 %}
In this example, the module-level comment provides an overview of the module, and each function is documented with a description, examples, and any relevant panics.
## Documentation Tests
One of the powerful features of Rust's documentation system is the ability to include tests directly within your documentation comments. These are known as documentation tests, and they serve a dual purpose: they provide examples of how to use your code and ensure that the examples remain correct as your code evolves.
### Writing Documentation Tests
To write a documentation test, you simply include code examples within triple backticks in your doc comments. Rust's `rustdoc` tool will automatically extract these examples and run them as tests when you run `cargo test`.
Here's a basic example:
{% embed https://gist.github.com/gritmaxuk/5ec9a9a7bb8d4fd08d8fd08db68974fa %}
In this example, the code within the triple backticks is a documentation test. When you run `cargo test`, this code will be compiled and executed to ensure that it produces the expected result.
### Benefits of Documentation Tests
1. **Ensuring Accuracy**: Documentation tests ensure that your examples are always accurate and up-to-date. If you change your code in a way that breaks an example, the test will fail, alerting you to the issue.
2. **Providing Working Examples**: Users can trust that the examples in your documentation actually work, as they are tested alongside your code.
3. **Reducing Maintenance**: By embedding tests in your documentation, you reduce the need for separate example code files, making it easier to maintain consistency between your code and its documentation.
### Advanced Usage
You can also include multiple examples and more complex scenarios in your documentation tests. Additionally, you can use attributes to control the behavior of these tests.
For instance, you might want to ignore certain tests or only run them under specific conditions:
{% embed https://gist.github.com/gritmaxuk/30b1637f22aa55eadc8df7c674a296fc %}
In this example, the second test is ignored because it demonstrates a panic scenario. You can use the `ignore` attribute to prevent certain tests from running by default.
### Running Documentation Tests
To run your documentation tests, simply use the `cargo test` command. This will compile and run all tests, including those embedded in your documentation comments.
```sh
cargo test
```
By incorporating documentation tests into your workflow, you can ensure that your documentation remains accurate and useful, providing real value to users of your code.
## Conclusion
Writing good documentation is an essential skill for any Rust developer. By following the best practices outlined in this guide, you can create documentation that is clear, concise, and helpful to your users. Remember to use `rustdoc` to generate your documentation, and keep it up to date as your code evolves. With well-written documentation, you can make your code more accessible, maintainable, and enjoyable to use.

React components are... | 0 | 2024-06-12T13:44:57 | https://dev.to/ark7/react-components-14eg | webdev, javascript, beginners, programming | React components are the fundamental building blocks of a React application.
React components are **reusable**, **self-contained** pieces of code that define how a portion of the user interface (UI) should appear and behave.
The beauty of React is that it allows you to break a UI (User Interface) down into independent reusable chunks, which we will refer to as components. The following picture should give you an idea of how to do that when building a very basic app.
For example, this website could be broken into the following components:
- _App_, which represents your main application and will be the parent of all other components.
- _Navbar_, which will be the navigation bar.
- _MainArticle_, which will be the component that renders your main content.

Components can be thought of as custom HTML elements that React uses to build the UI.
React breaks down its components into two types. I.e functional components and class components.
We are going to discuss each one of them one by one.
## Functional components
Functional components are JavaScript functions that accept props(properties) as arguments and return React elements (JSX).
Functional components do not have their own state or lifecycle methods, but with the introduction of hooks in React 16.8, functional components can now manage state and side effects.
Here is an example of a functional requirement using props.
## Class Components:
Class Components are ES6 classes that extend React.Component and must define a render method that returns React elements.
Class components can have their own state and lifecycle methods, making them more powerful than functional components (prior to hooks).
Here is an example:
## React components key concepts:
**1. JSX:**
JSX is a syntax extension for JavaScript that looks similar to HTML and is used to describe the UI.
React components typically return JSX to define what the UI should look like.
Here is a JSX sample:
**2. Props:**
Props (short for properties) are read-only inputs to components. They are used to pass data from parent components to child components.
Here is a sample:
**3. State:**
State is a built-in object in class components (or managed via hooks in functional components) that holds data that may change over the component's lifetime.
State changes can trigger re-renders of the component.
Here is an example:
This bring us to the end of our discussion on React components.

1,884,487 | How to remember everything for standup | Do you have trouble remembering your software engineering accomplishments and todos for your standup... | 0 | 2024-06-12T13:38:59 | https://www.beyonddone.com/blog/posts/how-to-remember-everything-for-standup | standup, productivity, career, softwaredevelopment | Do you have trouble remembering your software engineering accomplishments and todos for your standup update? Perhaps you work hard. You juggle a lot of tasks. You help your coworkers. But when the daily standup meeting comes around, you can't seem to remember everything.
I'll review the advantages and disadvantages of some common standup preparation strategies so you'll never sell yourself short or forget a task again.
## Option #1 Take notes
Many experienced engineers take notes whenever they switch to a different task or leave their desks. They write what they're currently working on, what they've done, and some thoughts on the current task they are working on. You can do the same.
I've encountered a lot of engineers who keep a journal and pen around, but you could also use a note-taking app like [Notes](https://support.apple.com/guide/notes/welcome/mac), [Obsidian](https://obsidian.md/), or [Notion](https://www.notion.so/).
Reference these notes before or during standup.
### Advantages
- Full creative control. You can have whatever you want in your notes. You are limited only by your imagination.
- The notes are wherever you want to keep them, whether that is in a physical journal or your favorite note-taking app.
- If you are very particular, extremely disciplined, and extremely organized this may be the path for you.
### Disadvantages
- Every item needs to be manually entered or written down.
- The notes are only as good as your consistency and discipline. If you forget to write something down, that thing won't be in your notes.
- Your ability to quickly grok what's going on in your professional life for a standup update depends upon the quality of your note-taking organization.
## Option #2 Use bookmarks
The second option involves setting up bookmarks in your web browser so you can quickly review what you've done 5-10 minutes before the standup meeting.
Take a look at our guide on how to track your [GitHub todos and accomplishments](https://www.beyonddone.com/blog/posts/github-todos-and-accomplishments) and how to track your [Jira todos and accomplishments](https://www.beyonddone.com/blog/posts/jira-todos-and-accomplishments). From there, you can set up some bookmarked pages to reference before the standup meeting.
### Advantages
- Uses dashboards maintained by GitHub and Jira.
- Less reliant on self-discipline and superhuman organizational skills.
### Disadvantages
- The dashboards are not comprehensive and do not include all your todos and accomplishments.
- The dashboards are platform-specific. You'll need at least two browser tabs to thoroughly review where you are at.
- You'll have to look at timestamps to determine what has happened since the last standup update.
## Option #3 BeyondDone App
The final option is the BeyondDone app, which offers you the ability to see all your todos and accomplishments in one special automatically generated standup update page.
There's even a copy/paste button so you can quickly drop the update in Slack.
BeyondDone allows you to configure the cadence and times of your standups so that the standup page always shows the relevant todos and accomplishments since your last standup meeting.
I use BeyondDone every day and it has turbocharged my ability to stay on top of things and sell myself better in standup.
I encourage you all to take a look at [BeyondDone's features](https://www.beyonddone.com) and [sign up today](https://www.beyonddone.com/auth/signup). There's a 30-day free trial and no payment information is required up-front.

1,885,831 | RTT Reduction Strategies for Enhanced Network Performance | Round-trip time (RTT) stands as a pivotal metric for networking and system performance. It encloses... | 0 | 2024-06-12T13:37:16 | https://www.softwebsolutions.com/resources/reduce-rtt-optimize-network-performance.html | aws, cloud, rtt, cloudfront | Round-trip time (RTT) stands as a pivotal metric for networking and system performance. It encloses the time taken for a data packet to travel from its source to its destination and backward. This measurement is significant for determining the responsiveness and efficiency of communication channels within a network infrastructure.
RTT measures the latency in transmitting data across networks. It comprises transmission time, delay, and processing time at both ends of the communication. A lower RTT denotes faster data transfer and seamless interactions. This is crucial for applications that require real-time responsiveness, like online gaming, video conferencing, and financial transactions. This makes it imperative for organizations to reduce RTT.
In this blog we will explore the intricacies of RTT, explaining its significance in network performance optimization. We will also explore actionable strategies and best practices that will help reduce RTT and enhance user experiences and operational efficiencies across digital ecosystems.
## The significance of RTT in networking
As we discussed above, RTT is crucial to networking and has a significant impact on user experience and system performance. Comprehending the significance of RTT reveals the fundamental principles of effective data transfer and network agility.
RTT is important for more than just individual transactions; it affects the overall scalability, dependability, and efficiency of the network. High RTT values can result in poor user experiences, higher packet loss, and slow performance. On the other hand, throughput, quality of service (QoS), and network resilience are all increased when RTT is optimized.
RTT is crucial for networking environments because it helps to optimize data flow, guarantee uninterrupted connectivity, and create strong digital ecosystems. Gaining an understanding of RTT’s complexities enables enterprises to improve network performance, proactively handle latency issues, and provide outstanding user experiences.
## Importance of having RTT less than 100ms
Low RTT values signify that data travels swiftly between endpoints, leading to faster response times for applications and a smoother user experience. Conversely, high RTT values can cause delays and sluggish performance.
## Measuring RTT
Measuring and computing RTT are essential elements in evaluating network performance and enhancing data transfer. Knowing the precise measurement and computation of RTT enables enterprises to detect latency problems, optimize network setups, and improve overall system performance.
There are many tools and methods available for measuring RTT, and each one provides insights into a different aspect of network performance and latency. RTT measurement frequently makes use of ping commands, network monitoring software, and specialized diagnostic tools. By starting data packet exchanges between the source and destination locations, these tools measure how long it takes for packets to finish their round journeys.
To calculate RTT, we must examine how much time passes between the sending and receiving of packets and account for processing times, network propagation delays, and other latency factors.
The RTT calculation formula is simple to use:
**_RTT = Time of arrival (TOA) – Time of departure (TOD)_**
Where:
- Time of arrival (TOA): The timestamp when the data packet reaches its destination.
- Time of departure (TOD): The timestamp when the data packet was sent from its source.
## Factors influencing RTT and how to solve them:
**Network congestion**
**Influence:** High network traffic and congestion causes delays in data packet transmission and processing and impacts RTT.
**Solution:** We can implement congestion control mechanisms and load balancing strategies to improve congestion-related latency problems.
**Physical distance**
**Influence:** The geographical distance between network endpoints contributes to RTT, with longer distances typically resulting in higher latency.
**Solution:** By leveraging content delivery networks (CDNs) and optimizing routing paths, we can minimize data travel distances and reduce RTT.
**Network infrastructure**
**Influence:** The quality and efficiency of network components, including routers, switches, and cables, influence RTT.
**Solution:** We must upgrade hardware, optimize network configurations, and implement quality of service (QoS) policies to mitigate infrastructure-related latency.
**Protocol overhead**
**Influence:** The protocols used for data transmission, such as TCP/IP, introduce overheads that affect RTT.
**Solution:** Fine-tune protocol parameters, optimize packet sizes, and implement protocol optimizations to enhance data transfer efficiency and reduce RTT.
**Packet loss and retransmissions**
**Influence:** Packet loss and subsequent retransmissions contribute to RTT, especially in unreliable network environments.
**Solution:** Employ error detection and correction mechanisms, along with packet loss mitigation strategies to minimize RTT fluctuations that are caused by lost or retransmitted packets.
**Network jitter**
**Influence:** Network jitter impacts RTT consistency.
**Solution:** Implement jitter buffering, prioritize traffic, and optimize network paths to mitigate jitter-related latency and stabilize RTT measurements.
**Server performance**
**Influence:** The responsiveness and processing capabilities of servers at both ends of the communication affect RTT.
**Solution:** Optimize server configurations, leverage caching mechanisms, and deploy edge computing solutions to reduce server-side latency and improve RTT.
## Strategies for reducing round-trip time (RTT)
**1. Optimize network configuration:** Fine-tuning network configurations, including routing protocols, quality of service (QoS) settings, and network topologies, reduces RTT by optimizing data transmission paths and minimizing packet routing delays.
**2. Implement content delivery networks (CDNs):** Leveraging CDNs distributes content closer to end users, reducing data travel distances and lowering RTT. CDNs cache content, optimize delivery routes, and mitigate latency, enhancing overall network performance.
**3. Utilize caching mechanisms:** Implementing caching mechanisms at strategic points within the network reduces RTT by serving frequently accessed content locally. Caching minimizes data retrieval times, alleviates server load, and improves data access speeds.
**4. Deploy edge computing solutions:** Edge computing brings computing resources closer to users, reducing RTT by minimizing data travel distances and processing latency. Edge servers process data locally, enhancing real-time responsiveness and reducing dependency on centralized servers.
**5. Optimize protocol parameters:** Fine-tuning protocol parameters, such as TCP window size, packet size, and congestion control algorithms, optimizes data transfer efficiency and reduces RTT. Protocol optimizations mitigate overheads and improve overall network responsiveness.
**6. Implement packet loss mitigation strategies:** Addressing packet loss issues through error detection and correction mechanisms, packet retransmission strategies, and network redundancy reduces RTT fluctuations caused by lost or delayed packets.
**7. Leverage quality of service (QoS) policies:** Prioritizing critical traffic, implementing traffic shaping policies, and managing bandwidth allocation through QoS policies improve RTT for mission-critical applications. QoS optimizations ensure timely delivery of high-priority data, minimizing latency and ensuring consistent performance.
**8. Upgrade network infrastructure:** Investing in modern networking hardware, upgrading bandwidth capacity, and optimizing network components enhance data transmission speeds, reduce congestion-related delays, and lower RTT.

React is a fantastic tool which has dominated the... | 0 | 2024-06-12T13:36:20 | https://dev.to/alishgiri/why-i-chose-svelte-over-react-29i9 | svelte, react, javascript | Svelte and React are both used for Web development. React is a fantastic tool which has dominated the industry for a while now whereas Svelte is newer in the field and is gaining significant popularity.
## Overview
When I first heard about Svelte I wanted to try it out and was surprised to see how less code you have to write to do the same amount of work in React.
Lets take a look at code below,
### React
```react
import { useState } from 'react';
const FormExample = () => {
const [name, setName] = useState();
const [age, setAge] = useState();
function handleNameChange(event) {
setName(event.target.value);
};
function handleAgeChange(event) {
setAge(event.target.value);
};
return (
<div>
<input type="text" value={name} onChange={handleNameChange} />
<input type="text" value={age} onChange={handleAgeChange} />
<p>Name: {name}</p>
<p>Age: {age}</p>
</div>
);
}
export default FormExample;
```
### Svelte
```svelte
<script>
let name = "";
let age = "";
</script>
<input type="text" bind:value={name}>
<input type="text" bind:value={age}>
<p>Name: {name}</p>
<p>Age: {age}</p>
```
You can clearly see how simple Svelte is.
Just from this example we can tell that React has a steep learning curve than Svelte.
Some of the learning curve of React includes:
- Concept of JSX and Virtual DOM.
- Different Hooks used for different purpose.
- Next.js for Server-side rendering (SSR).
- Handling bundle size as the app grows larger.
- Rapid upgrades to the ecosystem, difficult to keep up.
- Utilizing React Developer Tools for debugging.
- React Router for navigation.
On the other hand Svelte just uses plain Javascript, HTML and CSS. In addtion, it only introduces few new syntax making is easier to learn.
```svelte
<script>
let count = 0;
$: timesTwo = count * 2;
function onClick() {
count += 1;
}
</script>
<button on:click={onClick}>Click me!</button>
<p>{count} x 2 = {timesTwo}</p>
<style>
p {
color: blue;
}
</style>
```
## Bundle Size & Performance
Svelte app has lesser bundle size than for React app which also contributes to the faster app load and improved performance in the production.
The production built of the Svelte app is lighter and surgically updates the DOM without relying on any complex reconciliation techniques and use of Virtual DOM which adds more code to the bundle as in React.
## Conclusion
React is still the most famous tool for web development. Svelte is comparatively new and gaining popularity due to its ease of use.
When taking about cross-platform flexibility, Svelte also has [Svelte Native](https://svelte-native.technology) like the way React has [React Native](https://reactnative.dev) for mobile app development.

**Availability, fault tolerance, reliability, resilience. These are some of the terms that pop up when delivering digital services to users at scale. Acronyms related to Service Levels tend to pop up as well. Most developers have at least seen SLA, SLO and SLI and some even know what they mean. However, based on personal experience, not many people who work in the intersection of writing, delivering and maintaining software necessarily know how to make use of them in their software delivery process.**
In this fundamental level blog post I will explain what different Service Level concepts mean and how to use them effectively in the software delivery process.
I also did a talk at DevOps Finland on this topic, [Service Levels, Error budgets, and why your dev teams should care.](https://verifa.io/blog/service-levels-error-budgets-devops-finland-talk/)
## What is a Service Level and why does it matter?
Depending on the source, I have seen claims that anywhere from 40% to a [whopping 90% of a software systems lifetime costs](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3610582/) consist of operational and maintenance costs, making the development costs of the software pale in comparison. [Additionally, costs of even short service breaks and unplanned downtime are significant](https://assets.new.siemens.com/siemens/assets/api/uuid:3d606495-dbe0-43e4-80b1-d04e27ada920/dics-b10153-00-7600truecostofdowntime2022-144.pdf) and getting more expensive still. This goes to show that being able to maintain your service availability and preferably being able to preemptively react to service degradation is not just a matter of convenience, but carries a very real price tag with business consequences.
Service Level embodies the overall performance of your software system. It consists of goals that, when met, indicate that your system is performing at the desired level, and measurements which tell if those goals are being met, exceeded or if the system is underperforming. There are three distinct concepts associated with the Service Level: Service Level *Agreement* (SLA), Service Level *Objective* (SLO) and Service Level *Indicator* (SLI).
### Service Level Agreements
Service Level Agreements are the base level of performance and functionality you promise to your users, be those paying customers or developers using your internal tooling platform and databases. Typically SLAs are seen to relate to service availability and is expressed as a percentage like 99,9 (colloquially ‘three-nines’, ‘four-nines’ for 99,99% and so on), but soon we will see that this is a simplification. Especially in public cloud computing, failing to meet a set SLA carries a contractual penalty for the provider and a compensation to their clients, such as refunds or discounts, so it is in a provider’s best interest to react preemptively when the software system shows signs of degradation. That brings us to Service Level Objectives (SLOs).
### Service Level Objectives
Service Level Objectives are goal values you set for your software system. They are not contractually bound like SLA values, but they still define the minimum baseline for your software system to be considered functional. It is a good practice to set SLOs slightly stricter than the thresholds defined in your SLAs; if your SLA promises 99,5% availability, 99,7% SLO gives you some leeway to fix problems in your software before they manifest for your users and start incurring sanctions. Obviously, you want to detect the symptoms before you start violating your SLOs and you do that by monitoring and measuring your Service Level Indicators (SLIs).
### Service Level Indicators
Service Level Indicators are metrics you collect about your software system’s health. Often coined under general term of ‘availability’, SLIs are specific technical measurements the system produces. However, what constitutes of availability and unavailability varies from system to system. Straightforward simplifications on availability such as ‘my server is on and reachable 99,9% of the time’ can easily hide symptoms of a badly behaving system. SLIs should be values that actually matter to the users and their experience with the software system.
## What to measure and how?
So, general ‘availability’ is not a good enough metric. Why?
A very heavy-handed example would be an Industrial Control System (ICS) that is only used during the day when the work is done on the factory floor. However, there’s a bug in this ICS that causes random disconnections and freezes when a certain load is reached in the system. This happens frequently during the day, but never outside working hours. If you would only monitor for server health or network connectivity (instead of HTTP error codes for example), your metrics would never reveal the problem affecting your users. In this scenario it does not matter if your SLO is met as it does not give you insight to how your users interact with the systems and how they experience using it. In the worst case scenario your SLI is just plain wrong, but even a good SLI may hide bad behaviour if the measurement window is too wide.
A simplistic way to measure availability is to look at the ‘good time’ your system experiences divided by total time. In the example above, you could have a health check or a liveness probe periodically checking on the server health and everything would look fine based on it. A more refined approach to measuring availability would be to measure the [ratio of good interactions against the total number of interactions.](https://sre.google/workbook/implementing-slos/) Metrics like latency, error ratio, throughput and correctness might matter more to your users than just raw liveness. Server availability is the basic requirement, serving requests correctly and in a timely manner is what brings value.
As always with complex systems, there is no silver bullet to choosing correct SLIs. In some cases we could for example tolerate some number of false positives or incomplete data as long as we get it fast whereas in other cases we could be willing to tolerate a system with notable latency or subpar throughput if we can be sure that the data we get is always correct.
When you have identified your SLIs, you have to set SLOs and SLAs. As a rule of thumb, every system breaks somehow sometime. Even if you managed to build an infallible system, external forces like network congestion and hardware failure could hinder your performance. That’s why it is unrealistic to aim for 100% availability. The goals you set for your system are also not static. When developing and launching new software, you probably want to set your goals modestly for starters. As you gain more data on user interactions and loads your system experiences, you can re-evaluate the goals while you keep improving the software. This brings us to our next topic.
## Why should you care about service level in software development?
I have said it before and I will say it again: software development is a customer service job. No commercial software system exists for its own sake. There are end users, your clients, who get something out of the software you build and your software should meet their needs constantly if you want to succeed. While user research might tell you what features you should build next, your service level tells how the features you already built are performing. With the ‘you build it, you run it’ approach becoming more prevalent within the industry, maintaining existing products increasingly becomes an exercise in the realms of software development processes rather than just an operational task. Best of all, monitoring your service levels allows you to make data-driven decisions when working on your software system.
I had an interesting discussion about service levels with a colleague who is managing a software team in a product company. I asked if they had SLAs and SLOs in place and he assured me they do. I also queried about their working practices and he told me they work in two week sprints building new features, but every now and then, usually after major releases, they have so-called ‘cooldown’ sprints where they work on improving the existing code base, refactoring and erasing technical debt. I said that’s just great, fantastic even. Technical debt will stifle the productivity and development speed in the long run, so I applaud any formal efforts taken trying to fight it.
Then I asked a few harder questions that revealed some room for improvement. The first one was: “What do you do if your SLOs are not being met?” He told me, that their SLOs were regarded more like key performance indicators: something they should strive for but is not actively acted upon. The second question I asked was: “How do they determine when to have a cooldown sprint”. From the answer I deduced that the decision was made somewhat at whim and when the feature backlog was not actively bursting from the seams with high priority stuff.
My main gripe with these answers is that breaking an SLO should always warrant action. If there are no procedures tied to it, an SLO becomes hollow fluff. That does not mean you should treat all SLO violations as major incidents; it is as unrealistic to expect 100% availability as it is to meet SLOs 100% of the time. Failing to meet an SLO should at least cause the software development team to stop and consider if they should prioritise their work or, say, have a cooldown sprint.
Enter error budgets. It took a while to get here from the title. One could say that error budgets are a tool and indicator on how much you can… muck around before you have to start finding out. But what are they and how do they work?
## How to use error budgets in software development?
Consider your service has some availability SLO of 95% tied to a monthly aggregated SLI (which, as a side note, allows for terribly long outages of [1,52 days per month](https://availability.sre.xyz/)!). Now you are doing some top notch software development and consistently manage to achieve 97% availability (your software is uncooperative only some 43 minutes each day…). That means, you have 97%-95%=2% budget to do risky stuff that can break your software **before** you are breaking your SLO. In minutes, that is an additional 28,8 on top of the current downtime.
Now talking about doing risky things in the software development context might evoke thoughts about deploying very experimental features, prototypes or even untested changes (and if you considered that, it’s OK. It is called an intrusive thought and everyone has them), but these are quite extreme examples. One should bear in mind, that in software development any change carries inherent risk in complex interconnected systems. You can use error budgets to release more frequently and with more confidence. If you do canary deployments or A/B testing, you can roll out new features faster to a wider audience because your error budget gives you this leeway. You could plan and perform maintenance breaks knowing you will not violate your SLOs. I think one of the most important things is that you get a data-driven indicator which allows you to make informed choices when balancing between system reliability and innovating new features.
Building on the previous example, consider you introduce a new change to your software system. Everything seems fine until in a couple of days you find out that your daily downtime has gone from 43 minutes to some 58 minutes. You realise that the feature you shipped has caused some extra instability in your system and that this single feature just made a dent to your availability: from 97% to 96%. You are still not violating the SLO, but just this new feature is now taking 50% of your error budget, leaving you with less freedom to develop new features. If your outage time would have gone over 72 minutes per day, the error budget would show that you will run out of it before the end of the month: time to immediately switch over to maintenance mode before our end users start complaining!
Now you are sitting there with your error (and in a sense, development) budget cut in half, gnashing your teeth, even realising that maybe 95% SLO is not that high and some improvements must be made. What can be done before we spend the rest of our budget? That is when you should realise, that the error budget is there for you to spend! You look at your gutted budget and realise that even if you would not optimise the feature you just shipped, you could still afford 14 minutes and 24 seconds a day, or a whopping 7,2 hours per month downtime without breaking your SLOs. Encouraged, you and your team of developers and operations people (hopefully a somewhat overlapping group) can schedule a safe and informed downtime where you perform some much needed reliability improvements.
## In conclusion
When building and serving software you care both about evolving it, but also about its availability and reliability. Focusing too much on the former can result in software robust on features, but brittle in architecture and maintainability, eventually slowing down the development as the majority of time is spent firefighting yet another failure. Focusing too much on the latter grinds the development to a halt as the best way to ensure reliability is to avoid making changes.
Using Service Level Agreements, Objectives and Indicators and Error Budgets effectively in your software development process enables you to strike the right balance between change versus stability. They define common goals to your developers and operations, promoting co-operation and data-driven decision making. They give your teams more ownership and agenda over the products they build and make it easier to react to problems before they can take effect.

**TL;DR:** Learn to visualize each country’s global forest area percentage using the Syncfusion WPF Pie Chart. We’ll cover data preparation, chart configuration, and customization for a clear view of forest distribution!
Welcome to our Chart of the Week blog series!
Today, we’ll use the Syncfusion [WPF Pie Chart](https://www.syncfusion.com/wpf-controls/charts/wpf-pie-chart "WPF Pie Chart") to visualize each country’s percentage of global forest area in 2021.
The WPF Pie Chart is a circular graph that divides data into slices to show the proportion of each category. It’s perfect for illustrating percentages or parts of a whole, with each slice’s size corresponding to its value within the total dataset. You can customize the chart with different colors, labels, and interactions to enhance data visualization and user experience.
The following image shows the Pie Chart we’re going to create.[](https://www.syncfusion.com/blogs/wp-content/uploads/2024/06/Visualizing-the-global-forest-area-data-using-the-Syncfusion-WPF-Pie-Chart.png)
Let’s get started!
## Step 1: Gathering the data
First, gather the data regarding the [global forest area](https://data.worldbank.org/indicator/AG.LND.FRST.K2?most_recent_value_desc=true "Global forest area data"). You can also download this data in CSV format.
## Step 2: Preparing the data for the chart
Next, the data will be organized by creating a **ForestDataModel** class to define the structure of the forest area data and a **ForestDataViewModel** class to handle data manipulation and communication between the model and the Pie Chart.
The model represents the data you want to visualize, including properties such as country name, corresponding forest area, and percentage of the global forest area.
Refer to the following code example.
```csharp
public class ForestDataModel
{
public string? Country { get; set; }
public double Value { get; set; }
public double Percentage { get; set; }
}
```
Then, create the **ForestDataViewModel** class. It mediates between data models and user interface elements (e.g., Pie Charts), preparing and formatting data for display and interaction.
Refer to the following code example.
```csharp
public class ForestDataViewModel
{
public List<ForestDataModel> ForestDatas { get; set; }
public ForestDataViewModel()
{
ForestDatas = new List<ForestDataModel>();
ReadCSV();
}
}
```
Next, convert the CSV data into a dataset using the **ReadCSV** method. Refer to the following code example.
```csharp
public void ReadCSV()
{
Assembly executingAssembly = typeof(App).GetTypeInfo().Assembly;
Stream inputStream = executingAssembly.GetManifestResourceStream("ForestSampleWPF.ForestData.csv");
List<string> lines = new List<string>();
if (inputStream != null)
{
string line;
StreamReader reader = new StreamReader(inputStream);
while ((line = reader.ReadLine()) != null)
{
lines.Add(line);
}
lines.RemoveAt(0);
double otherValues = 0;
double totalValue = 0;
foreach (var dataPoint in lines)
{
string[] data = dataPoint.Split(',');
var value = double.Parse(data[3]);
if (value >= 915000)
{
ForestDatas.Add(new ForestDataModel() { Country = data[1], Value = value });
totalValue = totalValue + value;
}
else
{
otherValues = otherValues + value;
}
}
totalValue = totalValue + otherValues;
ForestDatas = ForestDatas.OrderByDescending(data => data.Value).ToList();
ForestDatas.Add(new ForestDataModel() { Country = "Others", Value = otherValues });
AddPercentage(totalValue);
}
}
private void AddPercentage(double totalValue)
{
foreach (var dataPoint in ForestDatas)
{
var percentage = (dataPoint.Value / totalValue * 100);
dataPoint.Percentage = percentage;
}
}
```
## Step 3: Adding a border
Before we create the Pie Chart, let’s enhance it with a border. This addition will elevate its visual appeal and clarity.
Refer to the following code example.
```xml
<Window x:Class="ForestSampleWPF.MainWindow"
xmlns:local="clr-namespace:ForestSampleWPF"
Title="MainWindow" Height="650" Width="860" >
<!--Set border for the Pie Chart -->
<Border Background="#40008B8B"
Width="800"
Margin="20"
BorderBrush="Black"
BorderThickness="2">
<!--Create the Pie Chart inside the border-->
</Border>
</Window>
```
## Step 4: Configure the Syncfusion WPF Pie Chart control
Now, configure the Syncfusion WPF Pie Chart control using this [documentation](https://help.syncfusion.com/wpf/charts/seriestypes/pieanddoughnut "Getting started with WPF Pie Chart").
Refer to the following code example.
```xml
<Window x:Class="ForestSampleWPF.MainWindow" xmlns:syncfusion="clr-namespace:Syncfusion.UI.Xaml.Charts;assembly=Syncfusion.SfChart.WPF">
<syncfusion:SfChart x:Name="Chart">
<syncfusion:PieSeries>
. . .
</syncfusion:PieSeries>
</syncfusion:SfChart>
. . .
</Window>
```
## Step 5: Bind the data to the WPF Pie Chart
Let’s bind the **ForestDatas** collection to the Syncfusion WPF **PieSeries**. Each country’s pie slice will represent its corresponding forest area (in sq km). Refer to the following code example.
```xml
. . .
<syncfusion:SfChart x:Name="Chart">
<syncfusion:PieSeries ItemsSource="{Binding ForestDatas}"
XBindingPath="Country"
YBindingPath="Value">
</syncfusion:PieSeries>
</syncfusion:SfChart>
```
## Step 6: Customize the WPF Pie Chart appearance
Now, let’s improve the readability of the Syncfusion WPF Pie Chart by customizing its [appearance](https://help.syncfusion.com/wpf/charts/appearance "Appearance customization in WPF Charts").
### Customize the header
First, add a header to the chart using the following code example, ensuring clarity and context. Enhance the [header](https://help.syncfusion.com/wpf/charts/header "Header in WPF Charts") with a border, grid layout, image, and label. Adjust image source, label content, font size, and padding as needed.
```xml
. . . .
<syncfusion:SfChart.Header >
<Border Margin="0,30,00,0">
<Grid x:Name="header" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="tree.png" Height="40" Width="40" HorizontalAlignment="Left"/>
<Label Content="Percentage of Global Forest Area by Countries in 2021"
FontSize="20"
FontWeight="SemiBold"
Padding="10"
FontFamily="Arial"
Foreground="Black"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Grid.Column="1"/>
</Grid>
</Border>
</syncfusion:SfChart.Header>
```
### Customize the chart series
Refer to the following code example to customize the Pie Chart series using the [Palette](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Charts.ChartBase.html#Syncfusion_UI_Xaml_Charts_ChartBase_Palette "Palette property of the WPF Charts"), [Stroke](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Charts.ChartSeries.html#Syncfusion_UI_Xaml_Charts_ChartSeries_Stroke "Stroke property of the WPF Charts"), [StrokeThickness](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Charts.ChartSeries.html#Syncfusion_UI_Xaml_Charts_ChartSeries_StrokeThickness "StrokeThickness property of the WPF Charts"), and other properties.
```xml
<syncfusion:PieSeries ExplodeOnMouseClick="True"
ExplodeIndex="7"
StartAngle="-120"
EndAngle="240" "
Palette="GreenChrome"
StrokeThickness="0.5"
Stroke="White">
</syncfusion:PieSeries>
```
### Customize the data labels
Let’s customize the data labels with the [LabelTemplate](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Charts.ChartAdornmentInfoBase.html#Syncfusion_UI_Xaml_Charts_ChartAdornmentInfoBase_LabelTemplate "LabelTemplate property of the WPF Charts") property.
Refer to the following code example.
```xml
. . . . .
<syncfusion:SfChart x:Name="Chart">
<syncfusion:PieSeries LabelPosition="Outside" >
<syncfusion:PieSeries.AdornmentsInfo>
<syncfusion:ChartAdornmentInfo LabelPosition="Inner"
ShowConnectorLine="True"
HighlightOnSelection="True"
SegmentLabelContent="LabelContentPath"
LabelTemplate="{StaticResource adornmentTemplate}"
ShowLabel="True">
</syncfusion:ChartAdornmentInfo>
</syncfusion:PieSeries.AdornmentsInfo>
</syncfusion:PieSeries>
</syncfusion:SfChart>
. . . . .
```
### Customize the chart legend
Now, customize the chart legend with the [ItemTemplate](https://help.syncfusion.com/wpf/charts/legend#customization "ItemTemplate property of WPF Charts") and [DockPosition](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Charts.ChartLegend.html#Syncfusion_UI_Xaml_Charts_ChartLegend_DockPosition "DockPosition property of the WPF Charts") properties.
Refer to the following code example.
```xml
. . . . .
<syncfusion:SfChart.Legend>
<syncfusion:ChartLegend DockPosition="Right"
ItemTemplate="{StaticResource legendTemplate}"
LegendPosition="Inside"
FontFamily="Arial"
FontWeight="Normal" Width="100" />
</syncfusion:SfChart.Legend>
. . . . .
```
After executing these code examples, we will get the output that resembles the following image.

> Test-Driven Development (TDD) is an approach that focuses on writing tests before writing the actual code. The general aim is to never write new functionality without a failing test first.
>
>In basic principle remember the following...
>**RED-GREEN-REFACTOR**
>
### Why TDD?
#### Occasionally you may see the following smells
- Tests that don't make sense.
- Poor use of testing practices like non descriptive context and it blocks lead to tests that are *hard to read*, which makes it very difficult to debug and maintain
- Sometimes a feature is not understood correctly, and edge cases are not addressed
- If you don't understand the spec how can you write it effectively?
- If you don't agree with the spec / ticket its best to raise it ASAP, *don't be afraid to speak out*!
- The same goes for working on bugs, if you have a very coupled system, ensure the fix proposed makes sense, but first *understand the feature*.
- Not testing the negative enough
- You should never assume that things are always going to go right (*cough *cough [Murphy's Law](https://en.wikipedia.org/wiki/Murphy%27s_law#:~:text=Murphy's%20law%20is%20an%20adage,at%20the%20worst%20possible%20time.%22)), we should be trying to catch possible errors and then write tests for it.
- The develop is not envisaging the properly. IE pretend to be the user.
- Sometimes its good to stop and think if what your are building / testing could use more enhancements or be friendlier to the user
- This isn't always possible but sometimes things are missed in designs or tickets you might find them yourself.
- Bloated tests
- Be careful not to over assert functionality, test what is key to the feature, make it simple and move on. Don't test things that your language does, test things the feature does.
>*Poorly written tests that over-specify the functionality of objects make systems harder to change, leading to frustration with the practice of testing and TDD itself.*
>
>*If an organization or project wants to see the value of testing in the long term, they need to ensure that test suites are kept lean, that tests are structured to aid developers in understanding them, and that failures provide useful feedback.*
>*[Source](https://jardo.dev/dont-assert-return-types-tdd)
#### Thankfully TDD can help!
### The Basic formula 🧑🍳
- **Write Test:** ✏️
Start by writing a test that defines the desired behaviour of a particular piece of code. This test should initially fail because the code to fulfil the behaviour hasn’t been implemented yet.
- **Run it, for Red:** 🔴
Run your test, knowing that its going to fail. It's okay to fail 😜
- **Write Code:** ✏️
Write the *minimum amount of code* necessary to make the test pass. In this pass we just want to make the thing work, it doesn't matter if its ugly.
- **Run it for Green:** 🟢
Run your test again, it should pass. If it doesn't pass, go back a step and keep working to get the green.
- **Refactor:** ✏️
After the test passes, refactor the code to improve its quality, maintainability, and efficiency. It's good here to look at OO principles and best practices often used in ruby. (In particular when building new classes or PORO's)
- **Run it for Green:** 🟢
Run your test again, ensuring it passes or go back to refactoring
- **Repeat on next item:** 🔁
Move onto the next piece of work and start again
> Handy tips!
>- As a first step I like to write up a skeleton of tests. So for instance I would copy the ticket and then draft up a skeleton of the context blocks and it blocks before hand.
> - Also break things down into segments and pieces of logic. Smaller bits are easier to manage.
> - Don't be afraid to use an AI when refactoring! I do it all the time its super handy, just make sure you ask the write questions and always take suggestions with a grain of salt. Sometimes it comes up with garbage but often theres excellent feedback. Write down what you learn use it next time!
### Use AAA to supercharge your tests
"Arrange, Act, Assert" (AAA) is a pattern for arranging and formatting code in unit tests. The idea is to divide your test method into three sections, which are separated by blank lines:
1. **Arrange**: This is where you set up the conditions for your test. This could involve creating objects, initialising data, setting up mocks or stubs, etc.
2. **Act**: This is where you perform the action that you're testing. Usually, this is a single function call.
3. **Assert**: This is where you check that the action you performed in the "Act" step produced the expected result.
Check out the following ruby example using RPSEC
```Ruby
RSpec.describe Calculator do
describe '#add' do
it 'adds two numbers' do
# Arrange
calculator = Calculator.new
# Act
result = calculator.add(2, 3)
# Assert
expect(result).to eq(5)
end
end
end
```
### Benefits of TDD ✅
- Forces developer to think deeper about the requirements and design of the spec
- Catch potential bugs early. 🐞
- Catch design flaws early, leading to higher code / feature quality.
- Debugging becomes faster and more efficient.
- Comprehensive tests makes refactoring safer ⛑️
### Tidbit about BDD
> BDD or Behaviour Driven Development, extends on Test driven development by writing test cases in a way anyone can understand.
- It focuses on the behaviour of software from the user’s perspective.
- It's an *agile software development technique*, in that it *encourages collaboration* between developers, QA and non-technical or business participants in a software project.
- Helps your tests tell a story of the feature with an emphasis on UX
#### Benefits of BDD ✅
- *Makes tests human readable,* meaning they are clearer and easier to understand, which makes them easier to maintain and fix any potential bugs. 📖
- Test cases can become documentation of the feature, in a well written test you don't have to read the code to understand what it does
- Forcing more collaboration between technical and non technical team members means a shared understanding of the requirements and overall a better piece of work
- You can catch unhandled use cases or possible feature enhancements early, saving precious time.

1,885,726 | How to Activate Debug Mode in WordPress | If you're struggling to identify the root cause of an unexpected error, enabling debug mode can be... | 0 | 2024-06-12T13:17:11 | https://dev.to/joanayebola/how-to-activate-debug-mode-in-wordpress-2l23 | wordpress, debug | If you're struggling to identify the root cause of an unexpected error, enabling debug mode can be the solution. Debug mode provides valuable insights into errors and malfunctions, helping you troubleshoot and fix them efficiently.
Fortunately, WordPress has a built-in debug mode that can help.
This article will guide you through the process of activating debug mode in WordPress, exploring different methods and best practices.
## What is Debug Mode in WordPress?
Debug mode in WordPress is a feature that helps developers and site administrators identify and resolve errors, warnings, and notices that occur within the WordPress environment. When enabled, debug mode provides detailed information about PHP errors, deprecated functions, and database queries, which can be invaluable for troubleshooting and optimizing the website. It essentially makes the internal workings of WordPress more transparent, allowing for a deeper understanding of any issues that might be affecting the site's performance or functionality.
## Why Use Debug Mode?
Using debug mode is essential for several reasons:
1. **Error Identification**: Debug mode highlights PHP errors, warnings, and notices that might otherwise go unnoticed. These errors can indicate issues in themes, plugins, or the WordPress core itself.
2. **Development**: During the development phase, debug mode helps ensure that code is functioning correctly and adheres to best practices. It aids in identifying deprecated functions and compatibility issues with newer versions of WordPress.
3. **Optimization**: By revealing slow database queries and other performance bottlenecks, debug mode assists in optimizing the website, leading to faster load times and a better user experience.
4. **Security**: Identifying and addressing errors early can prevent potential security vulnerabilities that could be exploited by malicious users.
## Important Considerations before Enabling Debug Mode
Before enabling debug mode, it's important to keep the following considerations in mind:
1. **Environment**: Debug mode should ideally be enabled in a development or staging environment, not on a live site. Displaying error messages on a live site can expose sensitive information to visitors and potentially compromise site security.
2. **Error Logging**: Instead of displaying errors directly on the site, consider logging them to a file. This approach keeps the site's frontend clean and secure while still providing access to detailed error information.
3. **Backup**: Always back up your website before making changes to its configuration. This precaution ensures that you can restore the site to its previous state if something goes wrong during the debugging process.
## Methods to Enable Debug Mode in WordPress
There are two primary methods to enable debug mode in WordPress: modifying the `wp-config.php` file and using a WordPress debugging plugin.
### Modifying the wp-config.php File
The `wp-config.php` file is the main configuration file for a WordPress site. To enable debug mode via this file, follow these steps:
1. **Access the File**: Use an FTP client or your web hosting control panel to access the `wp-config.php` file, which is located in the root directory of your WordPress installation.
2. **Edit the File**: Open the `wp-config.php` file in a text editor and add or modify the following lines of code:
```php
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
```
- `WP_DEBUG` enables the debug mode.
- `WP_DEBUG_LOG` directs error messages to a debug log file (`wp-content/debug.log`).
- `WP_DEBUG_DISPLAY` controls whether debug messages are displayed on the site. Setting this to `false` ensures errors are logged but not displayed to site visitors.
3. **Save and Upload**: Save the changes and upload the modified `wp-config.php` file back to your server.
### Using a WordPress Debugging Plugin
For those who prefer not to manually edit configuration files, several WordPress plugins can enable and manage debug mode. Some popular debugging plugins include:
- **Query Monitor**: Provides detailed information about database queries, PHP errors, and other performance metrics.
- **Debug Bar**: Adds a debug menu to the WordPress admin bar, displaying useful information about queries, cache, and other aspects of site performance.
To use a debugging plugin:
1. **Install the Plugin**: Go to the WordPress admin dashboard, navigate to Plugins > Add New, search for the desired plugin, and click "Install Now" followed by "Activate".
2. **Configure the Plugin**: Follow the plugin's instructions to enable and configure debug mode.
## Viewing and Analyzing Debug Information
Once debug mode is enabled, you can view and analyze the debug information in several ways:
1. **Debug Log File**: If you configured `WP_DEBUG_LOG`, check the `wp-content/debug.log` file for logged errors and warnings. This file provides a chronological record of issues, making it easier to track down the source of problems.
2. **Admin Dashboard**: Plugins like Query Monitor and Debug Bar display debug information directly in the WordPress admin dashboard. These tools offer a user-friendly interface for viewing and filtering error messages, database queries, and other relevant data.
When analyzing debug information, focus on identifying patterns and recurring issues. Address high-priority errors first, such as fatal errors and security warnings, before tackling less critical warnings and notices.
## Disabling Debug Mode
Once you've resolved the issues, it's important to disable debug mode to maintain site security and performance. To do this, follow these steps:
1. **Modify wp-config.php**: Open the `wp-config.php` file and change the following lines:
```php
define('WP_DEBUG', false);
```
Optionally, you can also remove or comment out the lines related to `WP_DEBUG_LOG` and `WP_DEBUG_DISPLAY`.
2. **Deactivate Plugins**: If you used a debugging plugin, deactivate it by going to Plugins > Installed Plugins in the WordPress admin dashboard and clicking "Deactivate".
Disabling debug mode ensures that error messages are no longer logged or displayed, reducing the risk of exposing sensitive information.
## Conclusion
Debug mode in WordPress is a powerful tool for developers and site administrators, offering detailed insights into errors, performance issues, and potential vulnerabilities.
Remember to always consider the environment in which you're debugging, prioritize the analysis of debug information, and follow best practices to ensure a seamless and effective troubleshooting process.

[apps worldwide](https://ripenapps.com/blog/mobile-app-industry-statistics/#:~:text=Currently%2C%20there%20are%208.93%20million,app%20downloads%20daily%20last%20year.)? Of those, 3.553 million are on the Google Play Store, and 1.642 million are on the Apple App Store.
Last year, there were around [250 million app downloads daily](https://ripenapps.com/blog/mobile-app-industry-statistics/#:~:text=Currently%2C%20there%20are%208.93%20million,app%20downloads%20daily%20last%20year.). With so many apps vying for attention, creating the perfect one requires a deep understanding of the programming language and its intricacies.
While languages like Swift and Kotlin are popular choices for native app development, Python offers a compelling cross-platform solution with the [Kivy framework](https://kivy.org/doc/stable/). Kivy allows you to create native-like applications for desktop, mobile, and even embedded devices, all while leveraging Python's simplicity and power.
Let's get started.
Check out this article: [Building a Simple Spy Camera with Python](https://blog.learnhub.africa/2024/02/26/building-a-simple-spy-camera-with-python/)
## Setting Up the Development Environment
Before diving into Kivy, you must ensure your development environment is properly configured. Follow these steps:
- **Install Python**
Kivy requires Python to be installed on your system. Using [Python 3.12](https://www.python.org/downloads/) [](http://)or later is recommended, as earlier versions may lack some necessary features. You can download the latest version of Python from the official website.
- **Set up a Virtual Environment (Optional but Recommended)**
It's a good practice to work within a virtual environment to isolate your project dependencies from other Python projects on your system. You can create a virtual environment using Python's built-in `venv` module or the `virtualenv` package.
For explanation, I will be using [VScode](https://code.visualstudio.com/download), and you can download and install it from here.
## Using `venv`
- Open your terminal or command prompt.
Navigate to the directory where you want to create your project.
- Run the following command to create a new virtual environment.
python -m venv myenv
This will create a new directory called `myenv` containing the virtual environment.
- Activate the virtual environment:
- On Windows, run: `myenv\Scripts\activate`
- On macOS or Linux, run: `source myenv/bin/activate`
Your terminal should now show the name of the activated virtual environment.

## Using `virtualenv`
- If you don't have `virtualenv` installed, you can install it using pip: `pip install virtualenv`
- Navigate to the directory where you want to create your project.
- Run the following command to create a new virtual environment:
virtualenv myenv
- Activate the virtual environment:
- On Windows, run: `myenv\Scripts\activate`
- On macOS or Linux, run: `source myenv/bin/activate`
Note you can use either `Virtualenv` or `venv`
## Install Kivy
With your virtual environment activated, you can now install Kivy using pip:
pip install kivy
This command will install the latest version of Kivy and its dependencies.
## Understanding Kivy's Architecture
Kivy follows a specific structure that keeps the user interface (UI) code separate from the application logic code. This separation makes it easier to manage and maintain your app as it grows in complexity.
Kivy uses two main components to achieve this separation:
- **Python Code** The Python code is where you write the logic for your application. This includes processing user input, manipulating data, and controlling the flow of your program. Think of this as the "brain" of your app, where all the behind-the-scenes work happens.
- **Kivy Language (KV) Files** The KV files define the visual elements of your app's user interface. This includes buttons, labels, and text inputs and how they are arranged on the screen. KV files use a special syntax that makes it easy to describe the UI components without writing much Python code.
## Creating Your First Kivy App
Let's start with a simple "Hello, World!" app to get a feel for Kivy's structure:
1. Create a new Python file, e.g., `main.py`, and add the following code:
from kivy.app import App
from kivy.uix.label import Label
class HelloApp(App):
def build(self):
return Label(text='Scofield, World!')
if __name__ == '__main__':
HelloApp().run()
Save the file and run it with Python: `python main.py`
You should see a window with the "Hello, World!" text displayed.
from kivy.app import App
from kivy.uix.label import Label
In the code above, we import the `App` and `Label` . In this case, we are importing the `App` class from the `kivy.app` module, and the `Label` class from the `kivy.uix.label` module. `App` is a class that represents our Kivy application, and `Label` is a widget (a user interface element) that displays text on the screen.
class HelloApp(App):
This line defines a new class called `HelloApp` which inherits from the `App` class we imported earlier. In Python, classes are like blueprints for creating objects. By inheriting from `App`, our `HelloApp` class will have all the functionality of a Kivy application.
def build(self):
return Label(text='Scofield, World!')
This is a method (a function inside a class) called `build`. Kivy expects every app to have a `build` method that returns the root widget of the user interface. We are returning a `Label` widget with the text "Scofield, World!". This label will be displayed on the screen when we run our app.
if __name__ == '__main__':
HelloApp().run()
This common Python idiom checks if the script is being run directly (not imported as a module). If that's the case, it creates an instance of our `HelloApp` class and calls the `run()` method on that instance.
The `run()` method is inherited from the `App` class and is responsible for starting the Kivy event loop, which keeps the application running and handles user input and other events.

## Building User Interfaces with Kivy Language
While you can define your UI entirely in Python code, using the Kivy Language (KV) is generally preferred for better separation of concerns and code organization. KV files use a declarative syntax to define the UI elements and their properties.
- Create a new file called `hello.kv` in the same directory as `main.py`.
- Add the following code to `hello.kv`:
Label:
text: 'Hello, World!'
Modify `main.py` to load the KV file:
from kivy.app import App
from kivy.lang import Builder
kv = Builder.load_file('hello.kv')
class HelloApp(App):
def build(self):
return kv
if __name__ == '__main__':
HelloApp().run()
When you run `main.py`, Kivy will load the UI from the `hello.kv` file.
## Adding Widgets and Layouts
Kivy provides rich widgets and layouts for building complex user interfaces. Widgets are individual UI elements like buttons, labels, and text inputs, while layouts manage the positioning and arrangement of these widgets.
- Create a new file called `button.kv` and add the following code.
BoxLayout:
orientation: 'vertical'
Button:
text: 'Click Me'
on_press: app.button_pressed()
- In `main.py`, add a `button_pressed` method to the `HelloApp` class:
from kivy.app import App
from kivy.lang import Builder
kv = Builder.load_file('button.kv')
class HelloApp(App):
def build(self):
return kv
def button_pressed(self):
print('Button pressed!')
if __name__ == '__main__':
HelloApp().run()
When you run `main.py` and click the button, you should see "Button pressed!" printed in your terminal or console.
## Handling User Input and Events
Kivy provides a robust event system that allows you to handle user input and other events within your application. This is crucial for creating interactive and responsive applications.
- Modify `button.kv` to include a `TextInput` widget.
BoxLayout:
orientation: 'vertical'
TextInput:
id: text_input
Button:
text: 'Click Me'
on_press: app.button_pressed(text_input.text)
- Update the `button_pressed` method in `main.py` to take the text from the `TextInput` widget.
def button_pressed(self, text):
print(f'You entered: {text}')
Now, when you run the app, type some text in the `TextInput` widget, and click the button, you should see the entered text printed in your terminal or console.
## Packaging and Deploying Your App
Once you've built your Kivy application, you must package it for deployment on various platforms. Kivy provides tools and documentation to help you package your app for desktop (Windows, macOS, Linux), mobile (Android, iOS), and even embedded devices (Raspberry Pi).
**Packaging for Android**
To package your app for Android, you'll need to install the `buildozer` tool.
pip install buildozer
Then, follow these steps:
- Create a new directory for your project and navigate to it.
- Run `buildozer init` to create a configuration file (`buildozer.spec`).
- Open the `buildozer.spec and customize the configuration file as needed (e.g., set the app title, package name, etc.). For starters, you can leave the file with the default name,` but keep in mind the default name.
- Copy your Kivy application files (`.py` and `.kv`) to the project directory.
- Run `buildozer android debug` to build a debug version of your app.
You might come across a missing dependency called `cython. Install` it using `pip`
`pip install cython`
After the build process completes, you'll find an `.apk` file in the `bin` directory. You can transfer this file to your Android device and install it.
## Best Practices and Tips
As with any development project, following best practices and adhering to industry standards is crucial for building high-quality, maintainable, secure applications. Here are some tips and best practices to keep in mind when working with Kivy:
- **Separation of Concerns**: Kivy encourages separating UI and application logic by using KV files for UI definition and Python code for application logic. Maintaining this separation improves code organization and maintainability.
- **Code Style and Conventions**: Follow the PEP 8 style guide for Python code and Kivy's recommended conventions for KV files to ensure consistent and readable code across your project.
- **Documentation and Comments**: Document your code with clear and concise comments, especially for non-trivial or complex sections. This will make it easier for others (or your future self) to understand and maintain the codebase.
- **Testing**: Implement unit and integration tests to ensure your application's functionality and catch regressions early. Kivy provides testing utilities and frameworks like Pytest and Unittest to help with this.
- **Performance Optimization**: Kivy applications can be resource-intensive, especially on mobile devices. Keep an eye on performance bottlenecks and optimize your code accordingly. Techniques like caching, lazy loading, and GPU acceleration can help improve performance.
- **Responsive Design**: Since Kivy applications can run on various screen sizes and resolutions, it's essential to design your UI with responsiveness in mind. Utilize Kivy's layout and widget properties to ensure your app looks and functions correctly on different devices.
- **Security Considerations**: When developing applications that handle sensitive data or have network connectivity, it's crucial to implement proper security measures. Follow best practices for secure coding, data encryption, and communication protocols.
- **Community Involvement**: Kivy has an active and vibrant community. Engage with other developers, contribute to the project, and stay up-to-date with the latest developments and best practices.
- **Third-Party Libraries and Plugins**: Kivy has a rich ecosystem of third-party libraries and plugins that can extend its functionality. Explore and leverage these resources when appropriate, but ensure they are well-maintained and secure.
- **Continuous Learning**: Mobile app development is a rapidly evolving field. Stay up-to-date with the latest trends, technologies, and best practices by reading documentation, attending conferences, and participating in online communities.

## Olá mundo!
Faz tempo desde o último artigo, mas estou de volta! Neste artigo, vou tentar explicar e aprimorar o entendimento sobre slices multidimensionais em Golang.
## O que é um slice multidimensional?
Um slice multidimensional é um slice que contém outros slices. Em outras palavras, é uma matriz de slices. Isso é útil quando você precisa de uma matriz de tamanho variável.
## Como funciona em Golang?
### Conceitos básicos
- Array multidimensional: um array multidimensional é um array que contém outros arrays como elementos. Em Go, você pode declarar um array de duas dimensões (por exemplo, uma matriz) como `var slice [3][3]int`.
- Slice: Uma fatia é uma referência a um segmento contínuo de um array. Fatias em Go têm uma capacidade (cap) e um comprimento (len) e podem ser redimensionadas.
### 1. Criando um slice 2D
Primeiro, criamos uma matriz 2D e a inicializamos com alguns valores. Em seguida, criamos um slice 2D e atribuímos a matriz 2D a ele.
```go
package main
import (
"fmt"
)
func main() {
matrix := [3][4]int{
{1, 2, 3, 4},
{5, 6, 7, 8},
{9, 10, 11, 12},
}
fmt.Println("Matriz 2D original:")
printMatrix(matrix)
}
```
Neste exemplo, criamos um slice multidimensional de inteiros. Cada elemento do slice principal é um slice de inteiros. Podemos acessar os elementos individuais da matriz usando a notação de colchetes duplos.
### 2. Fazendo Slice de Linhas Específicas
Criamos uma fatia para acessar partes específicas da matriz.
```go
func main() {
matrix := [3][4]int{
{1, 2, 3, 4},
{5, 6, 7, 8},
{9, 10, 11, 12},
}
fmt.Println("Matriz 2D original:")
printMatrix(matrix)
// Fatia da primeira linha
firstRow := matrix[0][:] // Equivalente a matrix[0][0:4]
fmt.Println("\nPrimeira linha como fatia:", firstRow)
// Fatia da segunda linha, mas apenas os dois primeiros elementos
secondRowPartial := matrix[1][:2]
fmt.Println("Parte da segunda linha:", secondRowPartial)
}
```
Neste exemplo, acessamos os elementos individuais da matriz usando a notação de colchetes duplos. O primeiro índice refere-se ao índice do slice principal e o segundo índice refere-se ao índice do slice interno.
### 3. Fazendo Slice de Colunas
Para acessar colunas, você precisa iterar pelas linhas e criar fatias das colunas desejadas.
```go
func main() {
matrix := [3][4]int{
{1, 2, 3, 4},
{5, 6, 7, 8},
{9, 10, 11, 12},
}
fmt.Println("Matriz 2D original:")
printMatrix(matrix)
// Fatia da primeira coluna
var firstCol []int
for i := range matrix {
firstCol = append(firstCol, matrix[i][0])
}
fmt.Println("\nPrimeira coluna como fatia:", firstCol)
// Fatia da segunda coluna
var secondCol []int
for i := range matrix {
secondCol = append(secondCol, matrix[i][1])
}
fmt.Println("Segunda coluna como fatia:", secondCol)
}
```
### 4. Função auxiliar para imprimir a matriz
```go
func printMatrix(matrix [3][4]int) {
for _, row := range matrix {
fmt.Println(row)
}
}
```
### Código completo
```go
package main
import (
"fmt"
)
func main() {
matrix := [3][4]int{
{1, 2, 3, 4},
{5, 6, 7, 8},
{9, 10, 11, 12},
}
fmt.Println("Matriz 2D original:")
printMatrix(matrix)
// Fatia da primeira linha
firstRow := matrix[0][:]
fmt.Println("\nPrimeira linha como fatia:", firstRow)
// Fatia da segunda linha, mas apenas os dois primeiros elementos
secondRowPartial := matrix[1][:2]
fmt.Println("Parte da segunda linha:", secondRowPartial)
// Fatia da primeira coluna
var firstCol []int
for i := range matrix {
firstCol = append(firstCol, matrix[i][0])
}
fmt.Println("\nPrimeira coluna como fatia:", firstCol)
// Fatia da segunda coluna
var secondCol []int
for i := range matrix {
secondCol = append(secondCol, matrix[i][1])
}
fmt.Println("Segunda coluna como fatia:", secondCol)
}
func printMatrix(matrix [3][4]int) {
for _, row := range matrix {
fmt.Println(row)
}
}
```
## Conclusão
Compreender o conceito de slices multidimensionais é essencial para qualquer desenvolvedor que deseja manipular estruturas de dados complexas de forma eficiente. Esse conhecimento não apenas aprimora a capacidade de lidar com arrays em várias linguagens, mas também simplifica a execução de operações complexas, aumentando a clareza e a manutenibilidade do código. Ao dominar o uso de slices multidimensionais, você ganha uma ferramenta poderosa para enfrentar desafios em áreas como processamento de imagens, ciência de dados e outras que exigem a manipulação de grandes volumes de dados. Essa habilidade se traduz em código mais eficiente e expressivo, capacitando você a resolver problemas de maneira ágil e eficaz, e a criar soluções mais robustas e escaláveis.

Kali ini kita akan membuat flying-in effect, tool-nya masih sama dengan yang sebelumnya yaitu kita akan menggunakan _intersection observer_. Seperti biasa kita siapkan code standar wajib : index.html, style.css dan app.js
```html
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

padding-top: 50px;
font-size: 100px;
}
```
Tampilan awalnya seperti ini ya
Nah kita ingin pada saat masuk section berikutnya ada semacam efek fly-in. Logic-nya kira-kira seperti ini :
1. Sembunyikan dulu section, kita sembunyikan pakai class `.section--hidden` di css
2. Tentukan target intersection antara section dan viewport
3. Kalau sudah kena targetnya, munculkan elemennya
**Dapatkan target**
```javascript
// app.js
const allSections = document.querySelectorAll('.section');
const revealSection = (entries, observer) => {
const [entry] = entries;
console.log(entry);
}
const sectionObserver = new IntersectionObserver(revealSection, {
root: null,
threshold: 0.15
});
allSections.forEach(section=>{
sectionObserver.observe(section);
section.classList.add('section--hidden');
});
```
Coba jalankan dan inspect element, scroll halaman sampai intersection pertama terjadi, tentunya section tidak adakan terlihat karena kita sembunyikan. Dari console inspect element kita dapatkan informasi sebagai berikut :
target : section#section--1.section.section--hidden
clasName : "section section--hidden"
id : "section--1"
**Munculkan elemennya**
Kode lengkap app.js sebagai berikut
```javascript
// app.js
const allSections = document.querySelectorAll('section');
const revealSection = (entries, observer) => {
const [entry] = entries;
console.log(entry);
// jika tidak terjadi intersection jangan lakukan apa-apa
if (!entry.isIntersecting) return;
// jika terjadi intersection class section--hidden dihilangkan
entry.target.classList.remove('section--hidden');
// supaya observer tidak diekseskusi terus menerus
observer.unobserve(entry.target);
};
const sectionObserver = new IntersectionObserver(revealSection, {
rot: null,
threshold: 0.1,
});
allSections.forEach((section) => {
sectionObserver.observe(section);
section.classList.add('section--hidden');
});
```
Hasilnya sebagai berikut :

1,885,728 | Checking Whitelisted Addresses on a Solidity Smart Contract Using Merkle Tree Proofs | Intro Hello everyone! In this article, we will first talk about Merkle Trees, and then... | 0 | 2024-06-12T13:03:30 | https://dev.to/muratcanyuksel/checking-whitelisted-addresses-on-a-solidity-smart-contract-using-merkle-tree-proofs-3odm | solidity, cryptocurrency, smartcontract, javascript | ## Intro
Hello everyone! In this article, we will first talk about Merkle Trees, and then replicate a whitelisting scenario by encrypting some "whitelisted" addresses, writing a smart contract in Solidity that can decode the encrption and only allow whitelisted addresses to perform some action, and finally testing the contract to see whether our method works or not.
IF you already know about merkle trees and directly start with the hands-on experience, you can skip the Theory part and start reading from the Practice section.
## Theory
In the evolving world of blockchain and decentralized applications (dApps), efficient and secure management of user access is paramount. One popular method for controlling access is through whitelisting, where only approved addresses can interact with specific functionalities of a smart contract. However, as the list of approved addresses grows, maintaining and verifying this list in an efficient and scalable manner becomes a challenge.
This is where Merkle trees come into play. Merkle trees provide a cryptographic way to handle large sets of data with minimal storage and computational overhead. By leveraging Merkle trees, we can efficiently verify whether an address is whitelisted without needing to store or process the entire list of addresses within the smart contract.
In this tutorial, we'll dive deep into how to implement a whitelisting mechanism using Merkle trees in Solidity. We'll cover the following key aspects:

# Understanding Merkle Trees
Merkle trees, named after computer scientist Ralph Merkle, are a type of data structure used in computer science and cryptography to efficiently and securely verify the integrity of large sets of data. In the context of blockchain and decentralized applications, Merkle trees offer significant advantages for managing and verifying data with minimal overhead.
What is a Merkle Tree?
A Merkle tree is a binary tree in which each leaf node represents a hash of a block of data, and each non-leaf node is a hash of its two child nodes. This hierarchical structure ensures that any change in the input data results in a change in the root hash, also known as the Merkle root.
Here’s a simple breakdown of how a Merkle tree is constructed:
Leaf Nodes: Start with hashing each piece of data (e.g., a list of whitelisted addresses).
Intermediate Nodes: Pair the hashes and hash them together to form the next level of nodes.
Root Node: Repeat the process until a single hash remains, known as the Merkle root.
This structure allows for efficient and secure verification of data.
Why Merkle Trees are Useful in Blockchain Applications
Merkle trees are particularly useful in blockchain applications for several reasons:
Efficient Verification: Merkle trees enable the verification of a data element's inclusion in a set without needing to download the entire dataset. This is achieved through a Merkle proof, which is a small subset of hashes from the tree that can be used to verify a particular element against the Merkle root.
Data Integrity: Any alteration in the underlying data will change the hash of the leaf node and, consequently, all the way up to the Merkle root. This makes it easy to detect and prevent tampering with the data.
Scalability: As the size of the dataset grows, Merkle trees allow for efficient handling and verification. This is particularly important in blockchain networks where nodes need to validate transactions and states without extensive computational or storage requirements.
Security: Merkle trees provide cryptographic security by using hash functions that are computationally infeasible to reverse, ensuring that the data structure is tamper-proof and reliable.
Practical Use Cases in Blockchain
Bitcoin and Ethereum: Both Bitcoin and Ethereum use Merkle trees to organize and verify transactions within blocks. In Bitcoin, the Merkle root of all transactions in a block is stored in the block header, enabling efficient transaction verification.
Whitelisting: In smart contracts, Merkle trees can be used to manage whitelisted addresses efficiently. Instead of storing a large list of addresses directly on-chain, a Merkle root can be stored, and users can prove their inclusion in the whitelist with a Merkle proof.
## Practice
Enough theory, now it is time to get our hands dirty. We are going to create an empty folder, and run the following command on the terminal to install Hardhat => npm install --save-dev hardhat
Then, with `npx hardhat init` command, we will start a Hardhat project. For this project, we will use Javascript.
After the project has ben initiated, we will install these following packages also => npm install @openzeppelin/contracts keccak256 merkletreejs fs
### Constructing the Merkle Root
In this step, we have a bunch of whitelisted addresses, we will write the script that will construct the merkle tree using those addresses. We will get a JSON file, and a single Merkle Root. We will use that merkle root later on to identify who's whitelisted and who's not.
In the main directory of the project, create `utils/merkleTree.js`
```js
const keccak256 = require("keccak256");
const { default: MerkleTree } = require("merkletreejs");
const fs = require("fs");
//hardhat local node addresses from 0 to 3
const address = [
"0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266",
"0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
//"0x3C44CdDdB6a900fa2b585dd299e03d12FA4293BC",
"0x90F79bf6EB2c4f870365E785982E1f101E93b906",
];
```
Note that we commented the address number 2.
You see we do not need to manually write the logic for the merkle tree, we're using a library for ease of development. The addresses are the first 4 addresses in Hardhat node. Do not send any money to them, their private keys are publicly known and anything sent to them will be lost.
Now, we will do the following:
- Hash all individual items in the address array (creating leaves)
- construct a new merkle tree
```js
// Hashing All Leaf Individual
//leaves is an array of hashed addresses (leaves of the Merkle Tree).
const leaves = address.map((leaf) => keccak256(leaf));
// Constructing Merkle Tree
const tree = new MerkleTree(leaves, keccak256, {
sortPairs: true,
});
// Utility Function to Convert From Buffer to Hex
const bufferToHex = (x) => "0x" + x.toString("hex");
// Get Root of Merkle Tree
console.log(`Here is Root Hash: ${bufferToHex(tree.getRoot())}`);
let data = [];
```
You see that we're logging the root hash. We will copy it when we run the script.
And now we'll do the following:
- Push all the proofs and leaves in the data array we've just created
- Create a whitelist object so that we can write into a JSON file
- Finally write the JSON file
```js
// Pushing all the proof and leaf in data array
address.forEach((address) => {
const leaf = keccak256(address);
const proof = tree.getProof(leaf);
let tempData = [];
proof.map((x) => tempData.push(bufferToHex(x.data)));
data.push({
address: address,
leaf: bufferToHex(leaf),
proof: tempData,
});
});
// Create WhiteList Object to write JSON file
let whiteList = {
whiteList: data,
};
// Stringify whiteList object and formating
const metadata = JSON.stringify(whiteList, null, 2);
// Write whiteList.json file in root dir
fs.writeFile(`whiteList.json`, metadata, (err) => {
if (err) {
throw err;
}
});
```
Now, if we run `node utils/merkleTree.js` in the terminal, we will get something like this: Here is Root Hash: 0x12014c768bd10562acd224ac6fb749402c37722fab384a6aecc8f91aa7dc51cf
We'll need this hash later.
We also have a whiteList.json file that should have the following contents:
```json
{
"whiteList": [
{
"address": "0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266",
"leaf": "0xe9707d0e6171f728f7473c24cc0432a9b07eaaf1efed6a137a4a8c12c79552d9",
"proof": [
"0x00314e565e0574cb412563df634608d76f5c59d9f817e85966100ec1d48005c0",
"0x1ebaa930b8e9130423c183bf38b0564b0103180b7dad301013b18e59880541ae"
]
},
{
"address": "0x70997970C51812dc3A010C7d01b50e0d17dc79C8",
"leaf": "0x00314e565e0574cb412563df634608d76f5c59d9f817e85966100ec1d48005c0",
"proof": [
"0xe9707d0e6171f728f7473c24cc0432a9b07eaaf1efed6a137a4a8c12c79552d9",
"0x1ebaa930b8e9130423c183bf38b0564b0103180b7dad301013b18e59880541ae"
]
},
{
"address": "0x90F79bf6EB2c4f870365E785982E1f101E93b906",
"leaf": "0x1ebaa930b8e9130423c183bf38b0564b0103180b7dad301013b18e59880541ae",
"proof": [
"0x070e8db97b197cc0e4a1790c5e6c3667bab32d733db7f815fbe84f5824c7168d"
]
}
]
}
```
### Verifying the proof in the smart contract
Now, check this Solidity contract out:
```js
// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.24;
import "@openzeppelin/contracts/utils/cryptography/MerkleProof.sol";
// Uncomment this line to use console.log
// import "hardhat/console.sol";
contract MerkleProofContract {
bytes32 public rootHash;
constructor(bytes32 _rootHash) {
rootHash = _rootHash;
}
function verifyProof(
bytes32[] calldata proof,
bytes32 leaf
) private view returns (bool) {
return MerkleProof.verify(proof, rootHash, leaf);
}
modifier isWhitelistedAddress(bytes32[] calldata proof) {
require(
verifyProof(proof, keccak256(abi.encodePacked(msg.sender))),
"Not WhiteListed Address"
);
_;
}
function onlyWhitelisted(
bytes32[] calldata proof
) public view isWhitelistedAddress(proof) returns (uint8) {
return 5;
}
}
```
What it does is the following:
- Imports Openzeppelin's merkle proof contract
- Enters the root hash we've just saved in the constructor. This means that there will be no more whitelisted accounts added, and it is final
- a private verifyProof function invokes Openzeppelin and requires the proof from the user
- a isWhitelistedAddress modifier makes sure that msg.sender is the whitelisted address. Without this modifier, anyone with the public whitelisted address could call the contract, now, only the owner of the whitelisted address can call
- a basic onlyWhitelisted function requires the user proof and returns 5. That's is, we just want to see if we can call this function as a non-whitelisted user or not
### Testing the contract
Now in the test folder create a MerkleProof.js file and add the following there:
```js
const { expect } = require("chai");
const { formatEther } = require("ethers");
const { ethers } = require("hardhat");
describe("MerkleProof", function () {
it("only whitelisted address can call function", async function () {
let owner, addr1, addr2;
let merkleTreeContract;
let rootHash =
"0x12014c768bd10562acd224ac6fb749402c37722fab384a6aecc8f91aa7dc51cf";
// async function setup() {
[owner, addr1, addr2] = await ethers.getSigners();
const MerkleTree = await ethers.getContractFactory("MerkleProofContract");
merkleTreeContract = await MerkleTree.deploy(rootHash);
console.log(merkleTreeContract.address);
// }
// beforeEach(async function () {
// await setup();
// });
const user = addr1;
const proof = [
"0xe9707d0e6171f728f7473c24cc0432a9b07eaaf1efed6a137a4a8c12c79552d9",
"0x1ebaa930b8e9130423c183bf38b0564b0103180b7dad301013b18e59880541ae",
];
console.log(
`user address: ${user.address} and proof: ${proof} and rootHash: ${rootHash}`
);
expect(
await merkleTreeContract.connect(user).onlyWhitelisted(proof)
).to.equal(5);
await expect(
merkleTreeContract.connect(addr2).onlyWhitelisted(proof)
).to.be.revertedWith("Not WhiteListed Address");
});
});
```
This test file works as such:
- owner, addre1 and addr2 are the first 3 addresses in Hardhat node
- deploys the merkle tree contract with the saved root hash
- user is addr1, that is the 2nd addess in whiteList.json file. We get the proof from there
-connects to a whitelisted user and calls the function, gets the correct value of 5
-connects with a non-whitelisted user (we did comment out the address number 2 at the very beginning ) and calls the function, is reverted.
Hope you enjoyed it! If you have any corrections or suggestions, please let me know in the comments.
Cheers!

1,885,724 | Why and When to Use Waterfall vs. Agile: A Business Perspective | Waterfall Methodology Use Cases: Well-defined requirements: Waterfall is... | 0 | 2024-06-12T13:00:52 | https://jetthoughts.com/blog/why-when-use-waterfall-vs-agile-business-perspective-management/ | agile, management, startup | ## Waterfall Methodology
### Use Cases:
- **Well-defined requirements**: Waterfall is the best project life cycle option for projects with precise, stable, and in-depth established requirements.
- **Regulatory Compliance**: This is fundamental in industries with substantial regulatory requirements. These requirements require the formulation of documentation of various stages, and regulatory bodies could authorize the performance of the same.
- **Predictable and Low-Risk Projects**: It fits projects with minimal risk possibilities, where possible outcomes can easily be worked out.
- **Complex Interdependencies**: This is best for projects that feature complicated interconnections between the phases, where one part involves another, and where execution and planning are of great importance.
### Business Benefits:
- **Structured Approach:** Step-by-step activities demonstrate the structure and method of the solution to achieve a complete product or service.
- **Detailed Documentation:** Detailed documentation is a valuable resource for both maintenance personnel and compliance auditors.
- **Predictability:** Known delivery timeframes and task benefits facilitate a better understanding of tasks, which leads to more accurate and less costly resource balance planning and budgeting.
- **Risk Management:** The engineering department can minimize the risk posed by additional work requirements through meticulous requirement analysis at the very beginning.
### Costs for Business:
- **Inflexibility:** Implementing changes in the project at a later stage may be very costly and sometimes impossible to achieve.
- **Long Feedback Loop:** If feedback is received early, there is always a chance that the work will be in sync with stakeholder goals.
- **High Initial Costs:** A big chunk of bold capital investment is the keen focus on planning and documentation.
- **Requires Skilled Teams:** Success requires teams with a high level of skill, collaboration, and experience to predict and make it right from the first try.
## Agile Methodology
### Use Cases:
- **Evolving Requirements:** Agile suits projects when the requirements change or evolve depending on the feedback.
- **Customer-Centric Focus:** Perfect for projects that utilize the customer's feedback to develop the final product.
- **High Uncertainty and Innovation:** This is the best way to implement innovative projects with uncertainty, where flexibility and rapid iteration are the keys.
### Benefits:
- **Flexibility and Adaptability:** The organization can make a quick shift in any situation whenever there are new developments and new information.
- **Continuous Improvement:** This way of continuous improvement starts when the product development is developed and with the regular feedback loops, the ones responsible for the product will be able to continuously improve it.
- **Customer Satisfaction:** The company provides a good product due to the customer's full participation in the design process.
- **Early Detection of Issues:** Regular testing and reviews help identify and resolve early, thus decreasing the possibility of significant defects.
### Costs:
- **Less Predictability:** The `flexible nature` of the project's scope can make it difficult to predict timelines and costs.
- **Potential for Scope Creep:** Without effective leadership, uncontrolled changes, known as scope creep, can happen due to changing requirements.
## Choosing the Right Path for Your Business
### Waterfall:
- **Profit Potential:** Using Waterfall's structured approach, the completion of big, complex projects is manageable, and the outcomes are expected. Moreover, it switches those risks presented by scope change to other areas where they are less prominent, making it easier to manage for less dynamic projects. Another aspect that makes implementation a challenge is the rigidity of the waterfall model. Every time new requirements are imposed, the cost of making changes increases. Further, the model's rigidity needs to enable customer feedback, bringing about unnecessarily expensive changes upon them.
- **Cost Considerations:** The costs of initial planning and documentation are high, and the inflexibility can make the changes, if necessary, costly when the requirements evolve in due course.
### Agile:
- **Profit Potential:** Due to the cyclical nature of Agile, companies can decrease the time-to-market time of their products to be released on the market more and more with each cycle. Thus, companies can keep up with the market and update their products with the feedback received. This is also the case with stone products produced based on incremented user feedback. As a result, the company can achieve higher customer satisfaction and competitive advantage.
- **Cost Considerations:** Agile projects can be staff-intensive, meaning they get the best out of the employee's commitment to the project, and the development team is also managed. In addition to stakeholder interactions, skilled teams are necessary to maintain projects. The fluid nature of the models means that the budget and time often do not follow the plan, but usually, they result in a product that satisfies users' requirements and the market. It is likely that both predictive budgeting and forecasting will be reduced since the agile methodic approach can potentially.
## Conclusion
Waterfall is a straight, organized approach that is good for projects with well-defined requirements and regulatory needs.
Agile is more flexible and adaptable, which can be a perfect fit for dynamic environments with changing requirements and allows companies to focus on customer satisfaction.
Some people find that Agile and Waterfall on the same team would be trouble. However, it depends on the circumstances. They may fail to play together in well-established projects based on well-defined requirements.
Some experts recommend the mixing of the two models. They argue that using both Agile and Waterfall methods in projects can provide the benefits of both methods.

Introduction to Cloud SRE and its Importance
--------------------------------------------
As cloud-based infrastructure and applications become increasingly complex, the role of Site Reliability Engineering (SRE) has become crucial in ensuring the smooth and efficient operation of these systems. Cloud SRE is responsible for designing, implementing, and maintaining highly reliable and scalable cloud-based services, with a focus on automation, monitoring, and incident response.
Effective cloud SRE is essential for businesses that rely on cloud-based technologies to power their operations. By optimizing the performance, availability, and security of cloud infrastructure and applications, cloud SRE teams can help organizations achieve greater agility, cost-efficiency, and customer satisfaction.
What is Distributed Tracing and How Does it Work?
-------------------------------------------------
Distributed tracing is a powerful observability technique that helps SREs and developers understand the behavior and performance of complex, distributed systems. In a cloud-based environment, where applications are often composed of multiple interconnected services, distributed tracing provides a comprehensive view of the end-to-end transaction flow, allowing teams to identify and resolve issues more efficiently.
The core principle of distributed tracing is to track the path of a request as it flows through the various components of a distributed system. This is achieved by injecting a unique identifier, known as a "trace ID," into the request as it enters the system. As the request is processed by different services, the trace ID is propagated, and additional context, such as timing information and error details, is captured and stored in a centralized tr## Benefits of Using Distributed Tracing in Cloud SRE
Implementing distributed tracing in a cloud SRE workflow can bring numerous benefits:
1. ****Improved Visibility****: Distributed tracing provides a comprehensive, end-to-end view of the interactions between different services and components within a cloud-based system. This enhanced visibility allows SRE teams to quickly identify the root cause of performance issues or errors, even in complex, highly distributed environments.
2. ****Faster Incident Resolution****: By tracing the path of a request and capturing detailed performance metrics, SREs can more easily pinpoint the specific service or component causing a problem. This enables faster incident resolution, reducing the impact on end-users and minimizing downtime.
3. ****Optimization of Application Performance****: Distributed tracing data can be used to identify performance bottlenecks, inefficient resource utilization, and other optimization opportunities within the cloud infrastructure and applications.

[Microsoft Build 2024](https://news.microsoft.com/build-2024-book-of-news/ "Microsoft Build 2024") was just as action-packed and busy as last year’s event, and [Syncfusion](https://www.syncfusion.com/ "Syncfusion") was honored to attend once again at the luminous Summit building of the Seattle Convention Center.
What makes Build such a special event for us is more than just the opportunity to show off what we’ve been working on over the past year. It’s about connecting with developers, understanding their new problems, and learning how Syncfusion can help.
## Syncfusion @ Build
At our booth, we showed attendees how Syncfusion is leveraging AI. We recently released the Syncfusion [HelpBot](https://www.syncfusion.com/blogs/post/syncfusion-helpbot-assistance "Blog: Syncfusion HelpBot: Simplified Assistance for Syncfusion Components") to help our customers find the right documentation to address their needs. Customers just describe their scenario, such as turning on a particular feature in a control, and HelpBot delivers the answer from our documentation, complete with relevant code and links for additional information. We also showed off the new [Q&A widget for Bold BI](https://help.boldbi.com/visualizing-data/visualization-widgets/qna-widget/?_gl=1*qkk7vd*_gcl_au*MTkwNzM2MTc5Ni4xNzE2OTA0NjQz*_ga*MTk5NjAzMTIwMy4xNzE2OTA0NjQ0*_ga_SRXJZD7EME*MTcxNzUzMTIzNi41LjAuMTcxNzUzMTIzNi42MC4wLjA. "Q&A widget for Bold BI"), which takes natural language descriptions from users to automatically generate visualizations of their data.
Other popular topics of discussion around our booth were BoldSign and the latest updates to our [React](https://www.syncfusion.com/products/whatsnew/react "What’s New in Syncfusion React UI Components"), [JavaScript](https://www.syncfusion.com/products/whatsnew/essential-js2 "What’s New in Syncfusion JavaScript UI Components"), [Angular](https://www.syncfusion.com/products/whatsnew/angular "What’s New in Syncfusion Angular UI Components"), [.NET MAUI](https://www.syncfusion.com/products/whatsnew/maui-controls "What’s New in Syncfusion .NET MAUI UI Controls"), and [WinForms](https://www.syncfusion.com/products/whatsnew/winforms "What’s New in Syncfusion WinForms UI Controls") component libraries. A fun conversation point that came up was [Metro Studio](https://www.syncfusion.com/downloads/metrostudio "Syncfusion Metro Studio"), our icon template tool that we rolled out way back in the days of Windows 8. Several visitors let us know that they still actively use it, proving that the right tool for the job isn’t always the newest one.

## Syncfusion Speakers
We were fortunate to host three sessions at Build. The audience was highly engaged, with many taking photos throughout the presentations, especially when the slides featured links to GitHub repositories for the demos—developers wanted to dive right in to see what they could apply to their own projects.
Michael Prabhu, senior product manager at Syncfusion, presented “[Create a Custom GPT with a Blazor and .NET MAUI Hybrid App.](https://www.youtube.com/watch?v=2R6helDo3C4&t=5s&pp=ygUXbWljaGFlbCBwcmFiaHUgbXMgYnVpbGQ%3D "YouTube Video: Create a custom GPT with Blazor and .NET MAUI Hybrid app")” In just 15 minutes, he created an app that targeted web, mobile, and desktop platforms and integrated an intelligent chatbot into it using Syncfusion controls.
Here’s what Michael said about the experience: “I was really excited to present how to create a custom GPT and create your own assistant programmatically without any SDK. This kind of assistant can help small organizations search through their information by file search instead of costly options like a database search. Attendees really appreciated that my Blazor application was also built as a .NET MAUI hybrid app, so it can be deployed in Android, iOS, and Windows. It was nice to see fellow developers eager to learn and create with AI, which is going to shape the future.”

### AI for Good
One of the most fascinating parts of Build was an informal discussion led by Microsoft team members working on the [AI for Good initiative](https://www.microsoft.com/en-us/research/group/ai-for-good-research-lab/overview/ "AI for Good Lab"). The audience was divided into small groups to discuss AI, such as concerns about its use and how to deploy it responsibly.
My group consisted of a mix of developers, designers, and marketers. When it was my turn to speak, I answered in terms of what I hope AI can do: I want to see applications and hardware designed to help the elderly communicate when they have a cluster of challenges, like vision loss, hearing loss, and cognitive impairment. Some AI applications can help with these individually, but I have yet to find one for people dealing with these challenges simultaneously. I also voiced my concern that the devices and software that I have seen assume a certain level of cognitive ability from the user. AI must be an accessible resource, regardless of the user’s cognitive and physical abilities.
At the conclusion of the discussion, each participant received a copy of the book _[AI for Good: Applications in Sustainability, Humanitarian Action, and Health by Juan M Lavista Ferres and William B. Weeks](https://www.microsoft.com/en-us/research/group/ai-for-good-research-lab/ai-for-good-book/ "Article: AI for Good: Applications in Sustainability, Humanitarian Action and Health")_.

</figure>
Microsoft CEO Satya Nadella always does an amazing job contextualizing the focus of each Build conference. Like last year, the focus was AI, but as Nadella noted, “It’s just that the scale, the scope is so much deeper, so much broader this time around.”
Indeed, where the previous year’s keynote was about extending applications with AI plugins, this year’s was about using AI to transform the world to help everyone and the rapid democratization of technology taking place through AI’s capabilities.
As an example, he noted a rural Indian farmer who used a GPT-3.5 interface developed by someone in the United States to explore and secure government farm subsidies that he had heard about on TV. Another example was how a developer in Thailand was using Phi-3 and GPT-4 to optimize his work on retrieval-augmented generation just weeks after Phi-3 was released.
Before diving into what new AI capabilities Microsoft developers can look forward to across Microsoft platforms, Nadella emphasized the essential role developers play in the success of AI. Standing in front of an enormous “Thank you,” Nadella said, “I want to start though with a very big thank you to every one of you who is really going about bringing about this impact to the world.”
Microsoft CTO Kevin Scott echoed this sentiment at the end of the keynote. “All we’re doing is building the platform…It’s you who are doing the work. You’re the ones who are making all of these things matter.”

Today we are not going to review 50 year old movies, but we are going to re view the 50 year old movies. You get it ?
So, today we are going to see what is SFX, VFX and CGI. What are their differences and in which movies where they used. So let's dive right in !
## Movies
Louis Le Prince's Roundhay Garden Scene, this film(2sec long) is considered as the first film ever. It released in 1888. This means movies are here before 200 years 🤯. From then onwards they have been evolving and changing a lot. At first movies were just all about shooting the film, combining them and releasing them. Imagine a world with no visual effects !
<img src='https://i.giphy.com/media/v1.Y2lkPTc5MGI3NjExazM0ZW1va24zNHpncjFiYjA0NGN2MG95azhpaHkzZ2VmdjF0cDllYSZlcD12MV9pbnRlcm5hbF9naWZfYnlfaWQmY3Q9Zw/1OYRPI5DZsCJO/giphy.gif'/>
Well, that did not last very long
## SFX ( special effects )
The execution of Mary, queen of scots. This film was the first to feature an SFX shot. This released in 1895. That was long back 😶. Well what are these special effects ? These effects are basically camera illusions. Like if put your finger close to the camera and someone far way in the right place. He will appear small sitting on finger. And then you snap him away. Well this was easy to do.
Another side of special effects is movable figures. Using stop motion we could basically create some creature appear to be moving. Such things are supposed to be special effects. I know this is difficult to understand but this is the first era of films using effects. Actually, this is not the end. Their is another type of special effects called miniatures. This means to use tiny things of what they want in the film and placing it in the perfect spot in front of the camera. This will make it look bigger.
Some famous examples of special effects in movies are the first Godzilla and king kong movies. Those which came in 1900s. In those movies Godzilla was actually a person with a costume ! The city below is miniature. Those were far less convincing. The space odyssey is another notable film that features use of special effects. Christopher Nolan is known to use special effects in his movies. Like in, INTERSTELLAR a certain explosion scene was made in real life but with miniature buildings. That looked spectacular and real. But things have changed with evolution of VFX
## VFX ( visual effects )
In 1902, A trip to the Moon became the first ever movie to use visual effects. But what is this visual effects ? Visual effects are scenes that are half real. Like maybe the people you see are all real but the background and setting is digitally made. This took movies really far. This made famous movies like Jurassic park possible. In that movie the humans, the destruction and a lot was really made. But the dinosaurs and a few other features were made using VFX. That movie had over 2000 visual effect shots and that is not the limit. I found out that Indian movies have a lot of VFX shots. For comparison, avengers endgame has 2500+ VFX shots. But these movies are a cut above:
- Syee raa narasimha reddy - 3700+ vfx shots
- Adhipursh - 4000+ vfx shots
- Ayalaan - 4500+ vfx shots
But, sometimes the VFX of INDIAN movies could go really wrong. Like look at this really unrealistic shot from ADHIPURSH (2023)
Adhipursh VFX ☝ 😭😭😭
> Not so fun FACT: I watched adhipursh movie for this post 😭 & it is horrible
Making VFX real-looking is a really complicated job for both the VFX artists and the director. There are lot of movies that were badly criticized for having bad VFX in their movies. Like catwoman, the scorpion king, the incredible hulk, Black widow and a lot more !
But there were certain things like mystical creatures in mystical world with no humans involved. Would you use costumes ? That would be really bad and money consuming. Like, the standard human costumes cost is $20000. If you want more personalized costumes for everyone, that would cost millions. So, people invented CGI which stands for computer generated imagery.
## CGI
Westworld is a movie released in 1973. Warner bros produced this masterpiece. This was the first movie to have convincing CGI. But, what the heck is CGI ? Well, CGI is completely artificial animation that looks real ( most of the times 😅). Westworld is a futuristic theme park where paying guests can pretend to be gunslingers in an artificial Wild West populated by androids. Instead of pouring money into Special effects and VFX. They introduced CGI. The CGI of westworld lasted only for 2 minutes. The CGI was nothing but different images animated. Modern days CGI is different. The westworld movie made 2880 images for just 2 minutes of CGI. If still don't get it. CGI is simply frame by frame drawing which are enhanced with shadows and lighting to make it look real.
Rememeber I said CGI changed now ? Yeah, now we use 3d software to do the job. So, CGI is just simple. But some movies have managed to make the most worst CGI moments like The lawn mover man. The lawn definitely deserves an image in this post. The last battle scene from hulk is also pretty crappy.
However some movies have done a really good job in use CGI like DUNE which has absolutely insane visuals. Even though iron man looked a little cartoonish, I liked the CGI of Avengers: Endgame. I would be doomed if I didn't mention AVATAR in this post, They have done a great job !

It... | 0 | 2024-06-12T12:43:53 | https://dev.to/platform_engineers/multi-stage-builds-for-microservices-a-practical-guide-27go | Microservices architecture has become a widely adopted approach for building complex systems. It involves breaking down a monolithic application into smaller, independent services that communicate with each other. Each microservice can be developed, deployed, and scaled independently, allowing for greater flexibility and resilience. However, managing the build process for multiple microservices can be challenging.
One effective way to manage the build process is by using multi-stage builds. This approach involves dividing the build process into multiple stages, each with its own Docker image. Each stage builds upon the previous one, allowing for efficient reuse of build artifacts and minimizing the final image size.
### Understanding Multi-Stage Builds
A multi-stage build typically consists of three stages:
1. **Build Stage**:
This stage is responsible for building the application code. It includes the necessary tools and dependencies required for the build process.
2. **Intermediate Stage**:
This stage takes the output from the build stage and prepares it for deployment. It may include tasks such as packaging the application, setting environment variables, and configuring the runtime environment.
3. **Final Stage**:
This stage creates the final Docker image that will be deployed to production. It typically includes only the necessary runtime dependencies and the application code.
### Example: Building a Python Microservice
Let's consider an example of building a Python microservice using a multi-stage build. Here's an example Dockerfile:
```dockerfile
# Build Stage
FROM python:3.9-slim as build
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
RUN pip install .
# Intermediate Stage
FROM build as intermediate
RUN pip freeze > requirements.txt
# Final Stage
FROM python:3.9-slim
WORKDIR /app
COPY --from=intermediate /app .
CMD ["python", "app.py"]
```
In this example, the build stage uses the `python:3.9-slim` base image and installs the necessary dependencies using `pip`. The intermediate stage takes the output from the build stage, freezes the dependencies, and prepares the application for deployment. The final stage uses the same base image as the build stage and copies the application code from the intermediate stage.
### Benefits of Multi-Stage Builds
Multi-stage builds offer several benefits, including:
- **Efficient Use of Resources**: By dividing the build process into stages, each stage can be optimized for its specific task, reducing the overall resource usage.
- **Smaller Final Image**: The final image only includes the necessary runtime dependencies, resulting in a smaller image size.
- **Improved Security**: The build stage can include tools and dependencies that are not necessary for the runtime environment, reducing the attack surface.
### Best Practices for Multi-Stage Builds
Here are some best practices to keep in mind when using multi-stage builds:
- **Keep Each Stage Focused**: Each stage should have a specific task and should not include unnecessary dependencies or tools.
- **Use Meaningful Stage Names**: Use descriptive names for each stage to make the build process easier to understand.
- **Optimize Each Stage**: Optimize each stage for its specific task, reducing the overall build time and resource usage.
### Conclusion
[Multi-stage builds](https://platformengineers.io/blog/multi-stage-build-for-ci-cd-pipeline-using-dockerfile/) are a powerful tool for managing the build process for microservices. By dividing the build process into stages, each stage can be optimized for its specific task, resulting in a more efficient and secure build process. As [Platform Engineering](www.platformengineers.io) continues to evolve, adopting multi-stage builds can help teams streamline their build processes and improve overall efficiency. | shahangita | |
