Selama berabad-abad, kopi menjadi minuman yang dipuja sekaligus dicela. Penelitian mengenai manfaat kopi mungkin sama banyaknya dengan bukti-bukti tentang efek buruknya. Kontroversi ini timbul karena begitu banyak zat yang dikandung dalam secangkir kopi.

Kandungan utama yang paling dikenal dari kopi adalah kafein. Namun, dampak yang ditimbulkannya terhadap tubuh bukan hanya disebabkan kafein, melainkan juga zat-zat lainnya. Untuk tahu lebih jelas kegunaan kopi dan efeknya bagi tubuh, simak uraian berikut ini.

Kandungan Nutrisi Kopi dan Waktu yang Tepat Meminumnya

Menurut sejarahnya, kopi pertama kali diminum oleh bangsa Yaman dalam sebuah upacara keagamaan. Namun, tanaman kopi saat ini sudah dibudidayakan di lebih dari 70 negara di dunia, termasuk Indonesia. Jenis yang paling banyak ditanam adalah kopi arabika dan robusta.

Meskipun kandungan vitamin dan mineralnya sangat sedikit, kopi tidak mengandung gula maupun karbohidrat. Selain kafein, kopi juga mengandung kalori, protein, riboflavin, pantothenic acid, kalium, mangan, magnesium, dan niasin.

Fakta lain akan kehebatan kopi adalah bahwa biji kopi mengandung lebih dari 1.000 macam antioksidan. Selain mengatasi peradangan dam menetralkan radikal bebas, antioksidan utama dalam kopi, chromogenic acid, terbukti mampu mencegah penyakit kardiovaskuler.

Lalu, kapan waktu terbaik untuk minum kopi? Ternyata, minum kopi di pagi hari tidak disarankan karena akan terjadi “tabrakan” antara hormon kortisol dengan kafein. Keduanya sama-sama berfungsi meningkatkan kewaspadaan sehingga manfaat kopi menjadi tidak efektif.

Kopi disarankan untuk diminum antara pukul 09.30–11.30 pagi agar manfaat kopi lebih terasa. Pada jam-jam tersebut, hormon kortisol berada pada level terendah. Minum kopi akan menggantikan kortisol dalam mengembalikan tingkat kewaspadaan.

Manfaat Kopi untuk Kesehatan

Banyak yang berpendapat bahwa minum kopi akan menyebabkan peningkatan detak jantung dan tekanan darah, serta insomnia.

Namun, penelitian-penelitian terbaru membuktikan bahwa di balik rasanya yang pahit, kopi memiliki banyak manfaat untuk kesehatan, yaitu sebagai berikut.

Mempertajam Memori Jangka Pendek

Kafein dalam kopi baik bagi otak karena memengaruhi area otak yang bertanggung jawab untuk konsentrasi dan memori jangka pendek. Dengan minum kopi setiap hari, kemampuan otak untuk berkonsentrasi dan mengingat peristiwa akan meningkat.

Mengurangi Risiko Alzheimer dan Demensia

Minum 3-5 cangkir kopi sehari dipercaya akan menurunkan risiko demensia dan Alzheimer hingga 65%. Hal ini disebabkan kopi mencegah pembentukan plak beta-amyloid dan menurunkan gula darah yang merupakan pemicu terjadinya Alzheimer dan demensia.

Mencegah Beberapa Jenis Kanker

Polifenol di dalam kopi merupakan antioksidan yang bersifat antikarsinogen. Bagi pria, minum kopi setiap hari akan mencegah kanker prostat, dan bagi wanita, kopi dapat mencegah kanker endometrium. Minum kopi juga terbukti mencegah kanker payudara, usus, dan hati.

Mencegah Diabetes

Minum kopi tanpa gula terbukti menurunkan risiko diabetes sebesar 7%. Selain meningkatkan efektivitas insulin, kopi mencegah kerusakan jaringan dan mengurangi penumpukan zat-zat racun seperti amyloid fibril yang ditemukan pada penderita diabetes.

Baik untuk Jantung

Anda mungkin sering mendengar bahwa minum kopi berbahaya untuk jantung. Namun, sebuah penelitian yang melibatkan 37.000 orang menunjukkan konsumsi kopi dengan dosis sedang bisa menurunkan 20% risiko terjadinya penyakit jantung.

Menjaga Kesehatan Hati

Kopi mampu menurunkan risiko kanker dan sirosis hati hingga 20%. Studi yang dilakukan di Turki menunjukkan, kopi akan menurunkan produksi enzim hati yang merupakan indikator terjadinya kerusakan pada hati.

Meringankan Depresi

Menurut para ahli saraf, kopi dapat mengaktifkan neurotransmitter sehingga mood Anda menjadi lebih baik. Yang termasuk dalam transmitter adalah hormon serotonin dan dopamin yang membuat perasaan menjadi lebih gembira.

Manfaat Kopi untuk Kecantikan

Selain memberikan manfaat dari dalam tubuh, pemakaian kopi untuk perawatan dari luar juga punya manfaat menakjubkan untuk kecantikan. Bagaimana cara memanfaatkan kopi untuk merawat kecantikan? Ini dia ulasannya.

Mengangkat Sel Kulit Mati

Kopi giling tidak larut dalam air sehingga cocok digunakan sebagai eksfolian untuk wajah dan tubuh. Caranya, campurkan bubuk kopi atau ampas kopi baru dengan gula dan minyak zaitun, lalu gosokkan ke permukaan kulit. Diamkan selama beberapa menit, lalu bilas hingga bersih.

Merevitalisasi Kulit

Selain kopi hitam, Anda juga bisa menggunakan kopi hijau untuk merevitalisasai kulit. Caranya, campurkan 3 sendok teh kopi hijau, 1 sendok teh susu, dan air secukupnya sampai menjadi pasta. Gunakan sebagai masker, biarkan hingga kering, lalu bilas air dengan dingin.

Melenyapkan Mata Panda

Untuk melenyapkan mata panda, aplikasikan bubuk kopi yang sudah sedikit dibasahi di sekitar mata. Kafein dalam kopi akan merangsang darah mengalir ke area mata sehingga kulit di sekeliling mata kembali kencang dan antioksidannya melindungi dari pengaruh sinar UV.

Mengobati Jerawat

Ada tiga senyawa penting yang membuat manfaat kopi sangat efektif untuk mengatasi jerawat, yaitu antioksidan, stimulan, dan chlorogenic acid. Scrub dari kopi akan membersihkan sel kulit mati yang menyumbat pori dan chlorogenic acid mencegah peradangan.

Merawat Kaki

Bubuk kopi juga bisa digunakan sebagai scrub untuk kaki sehingga bersih dan halus. Kandungan kafein pada kopi akan memperlancar sirkulasi darah ke kaki. Untuk menggunakannya, lakukan cara berikut.

• Seduh satu gelas besar kopi
• Tuang kopi bersama ampasnya ke dalam ember kecil.
• Setelah kopi dingin, rendam kaki sambil digosok perlahan.
• Bilas dengan air bersih, keringkan, dan gunakan lotion.

Menghitamkan Rambut

Warna hitam pada kopi bisa digunakan untuk menghitamkan rambut. Buatlah seduhan kopi kental, tunggu hingga dingin. Aplikasikan ke seluruh rambut, diamkan selama 30 menit–3 jam, lalu bilas. Anda juga bisa mencampurnya dengan minyak zaitun sebagai masker rambut.

Banyak studi menunjukkan, Anda akan mendapatkan manfaat kopi secara maksimal jika minum 1-2 cangkir kopi setiap hari. Akan lebih baik lagi jika Anda menggiling sendiri biji kopinya dan segera menyeduh serta meminumnya saat itu juga. Selamat ngopi!

For people running Homebrew (brew), and getting ‘Illegal Instruction: 4’ with certain software, but specifically wget. They recently switched brew to compile with ‘Nehalem’ instructions. The oldest architecture still officially supported by Mojave.

You can switch back to ‘core2’ instructions by editing /usr/local/Homebrew/Library/Homebrew/extend/os/mac/hardware.rb. Replace the elsif version and else branch result with “:core2” like this:
Code:

# frozen_string_literal: true

module Hardware
  def self.oldest_cpu(version = MacOS.version)
    if CPU.arch == :arm64
      :arm_vortex_tempest
    elsif version >= :mojave
      :core2
    else
      :core2
    end
  end
end

Add this to /etc/hosts to break access to the pre-built packages:
Code:

0.0.0.0 homebrew.bintray.com

You can then reinstall wget from source:
Code:

brew reinstall openssl wget --build-from-source

A “roll your own brew upgrade”; This oneliner will stuff all the upgradable packages on a single brew reinstall line. Maybe that will work but it may fail with some bash error like a ‘commandline too long’. I had a pretty long list so you’ll probably be fine.
Code:

nice -n20 brew reinstall $(brew upgrade --dry-run | grep -v 'Updating Homebrew...' | grep -v '==> Would upgrade .* outdated packages:' | sed 's/\(.*\) .* .* .*$/\1/g') --build-from-source

To check if you have any other pre-built packages installed, list all ‘internet bottles’ (needs jq):
Code:

brew install jq --build-from-source
brew info --json=v1 --installed | jq -r "map(select(.installed[].poured_from_bottle) | .name) | unique | .[]"

Reinstall all bottles that were not built yourself, but poored from an internet source (needs jq):
Code:

brew install jq --build-from-source
for p in $(brew info --json=v1 --installed | jq -r "map(select(.installed[].poured_from_bottle) | .name) | unique | .[]"); do
  nice -n20 brew reinstall $p --build-from-source
done

Oneliner version:
Code:

nice -n20 brew reinstall $(brew info --json=v1 --installed | jq -r "map(select(.installed[].poured_from_bottle) | .name) | unique | .[]") --build-from-source

Adapted from: https://stackoverflow.com/a/55038073/273668

You’ll probably need to run that a couple of times, since dependencies may be poured from an internet bottle.

This tutorial would be the last part of our laravel-news application. We have already completed the migrations and models, relationships among models, and creating and consuming RESTful API. To create the user interface for admin users I have planned to use Jetstream, Livewire, Sanctum, and Tailwind.

The admin dashboard needs to be secure. Laravel comes with Laravel Jetstream which provides login, registration, email verification, two-factor authentication, session management, API support via Laravel Sanctum, and optional team management. Jetstream is designed using Tailwind CSS and offers your choice of Livewire or Inertia scaffolding.

We have already used Laravel Sanctum to secure RESTful API in the previous tutorial.

If you like Vue.js as a templating language then choose the Inertia.js stack provided by Jetstream.

I am sticking to Blade as the templating language so I will use Livewire provided by Jetstream.

Laravel Livewire is a library that makes it simple to build modern, reactive, dynamic interfaces. When using Livewire, you may pick and choose which portions of your application will be a Livewire component, while the remainder of your application can be rendered as the traditional Blade templates you are used to.

Now let’s dive into code. There is make:livewire command which creates two files, one in app\Http\Livewire directory and another in resources\views\livewire directory.

Different versions of this command are as follows:

php artisan make:livewire foo
# Creates Foo.php & foo.blade.php

php artisan make:livewire foo-bar
# Creates FooBar.php & foo-bar.blade.php

php artisan make:livewire Foo\\Bar

php artisan make:livewire Foo/Bar

php artisan make:livewire foo.bar
# Creates Foo/Bar.php & foo/bar.blade.php

php artisan make:livewire foo --inline
# Creates only Foo.php

Before we start with our planned application, let us make few required edits in registration and profile update files provided by Laravel as there are first_name and last_name in our users table instead of the default name.

If you have not changed the default migration for users table then you may skip this step.

Open resources\views\auth\register.blade.php

<div>
<x-jet-label for="name" value="{{ __('Name') }}" />
<x-jet-input id="name" class="block mt-1 w-full" type="text" name="name" :value="old('name')" required autofocus autocomplete="name" />
</div>

and replace the above code with the following code

<div>
<x-jet-label for="first_name" value="{{ __('First Name') }}" />
<x-jet-input id="first_name" class="block mt-1 w-full" type="text" name="first_name" :value="old('first_name')" required autofocus autocomplete="first_name" />
</div><div>
<x-jet-label for="last_name" value="{{ __('Last Name') }}" />
<x-jet-input id="last_name" class="block mt-1 w-full" type="text" name="last_name" :value="old('last_name')" required autocomplete="last_name" />
</div>

Open resources\views\profile\update-profile-information-form.blade.php

<!-- Name -->
<div class="col-span-6 sm:col-span-4">
<x-jet-label for="name" value="{{ __('Name') }}" />
<x-jet-input id="name" type="text" class="mt-1 block w-full" wire:model.defer="state.name" autocomplete="name" />
<x-jet-input-error for="name" class="mt-2" />
</div>

and replace the above code with the following code

<!-- First Name -->
<div class="col-span-6 sm:col-span-4">
<x-jet-label for="first_name" value="{{ __('First Name') }}" />
<x-jet-input id="first_name" type="text" class="mt-1 block w-full" wire:model.defer="state.first_name" autocomplete="first_name" />
<x-jet-input-error for="first_name" class="mt-2" />
</div><!-- Last Name -->
<div class="col-span-6 sm:col-span-4">
<x-jet-label for="last_name" value="{{ __('Last Name') }}" />
<x-jet-input id="last_name" type="text" class="mt-1 block w-full" wire:model.defer="state.last_name" autocomplete="last_name" />
<x-jet-input-error for="last_name" class="mt-2" />
</div>

Then open app\Actions\Fortify\CreateNewUser.php and replace the create() with the following code:

public function create(array $input)
{
Validator::make($input, [
'first_name' => ['required', 'string', 'max:255'],
'last_name' => ['required', 'string', 'max:255'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => $this->passwordRules(),
])->validate();return User::create([
'first_name' => ['required', 'string', 'max:255'],
'last_name' => ['required', 'string', 'max:255'],
'email' => $input['email'],
'password' => Hash::make($input['password']),
]);
}

After that open app\Actions\Fortify\UpdateUserProfileInformation.php and replace update() and updateVerifiedUser() functions with the following code:

public function update($user, array $input)
{
Validator::make($input, [
'first_name' => ['required', 'string', 'max:255'],
'last_name' => ['required', 'string', 'max:255'],
'email' => ['required', 'email', 'max:255', Rule::unique('users')->ignore($user->id)],
'photo' => ['nullable', 'image', 'max:1024'],
])->validateWithBag('updateProfileInformation');if (isset($input['photo'])) {
$user->updateProfilePhoto($input['photo']);
}if ($input['email'] !== $user->email && $user instanceof MustVerifyEmail) {
$this->updateVerifiedUser($user, $input);
} else {
$user->forceFill([
'first_name' => $input['first_name'],
'last_name' => $input['last_name'],
'email' => $input['email'],
])->save();
}
}protected function updateVerifiedUser($user, array $input)
{
$user->forceFill([
'first_name' => $input['first_name'],
'last_name' => $input['last_name'],
'email' => $input['email'],
'email_verified_at' => null,
])->save();
$user->sendEmailVerificationNotification();
}

At this point, we are ready to go with Laravel’s default registration and profile update functionality.

Now move on to create pages to manage Categories, Tags, and Posts of our News Application.

Our Category page will look like the following and have the functionality to list all categories, edit a category, show all posts of a category, delete a category, and create a new category.

To create this page follow the below-mentioned steps:

php artisan make:livewire Categories\\categories

It will create Component and View files as discussed before.

Open app\Http\Livewire\Categories\Categories.php and write the following code

<?php
namespace App\Http\Livewire\Categories;use App\Models\Category;
use Livewire\Component;class Categories extends Component
{
public $categories, $title, $color, $category_id;
public $isOpen = 0;public function render()
{
$this->categories = Category::all();
return view('livewire.categories.categories');
}public function store()
{
$this->validate([
'title' => 'required',
'color' => 'required',
]);Category::updateOrCreate(['id' => $this->category_id], [
'title' => $this->title,
'color' => $this->color
]);session()->flash('message', $this->category_id ? 'Category Updated Successfully.' : 'Category Created Successfully.');$this->closeModal();$this->resetInputFields();
}public function delete($id)
{
Category::find($id)->delete();
session()->flash('message', 'Category Deleted Successfully.');
}public function edit($id)
{
$category = Category::findOrFail($id);
$this->category_id = $id;
$this->title = $category->title;
$this->color = $category->color;
$this->openModal();
}public function create()
{
$this->resetInputFields();
$this->openModal();
}public function openModal()
{
$this->isOpen = true;
}public function closeModal()
{
$this->isOpen = false;
}private function resetInputFields()
{
$this->title = '';
$this->color = '';
$this->category_id = '';
}
}

In the above code all the public properties are available to the view returned by render() method. List of all categories are passed to categories view by $categories variable.

To create or update a category the store() method is wired in the view. In this method after validation a category is added or updated in the database and accordingly message is flushed.

To delete a category delete() method is wired to delete button of view. The id of category to be deleted is passed to delete method from view and the same is deleted and message is flushed.

The edit() method is wired to edit button of the view. It passes id of the category. Then the category data is fetched by this id and all the public variables are populted with that data which will now be available to model form.

Then open resources\views\livewire\categories\categories.blade.php and write the following code

<x-slot name="header">
<h2 class="font-semibold text-xl text-gray-800 leading-tight">

Create one more view resources\views\livewire\categories\create.blade.php which will act as model to create and edit the category

To show all the posts belonging to a category create app\Http\Livewire\Categories\Categoryposts.php file and write the following code

<?php
namespace App\Http\Livewire\Categories;use App\Models\Category;
use App\Models\Post;
use App\Models\Tag;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\DB;
use Livewire\Component;
use Livewire\WithPagination;class Categoryposts extends Component
{
use WithPagination;
public $title, $content, $category, $post_id;
public $tagids = array();
public $isOpen = 0;
public $cid;public function mount($id)
{
$this->cid = $id;
}public function render()
{
return view('livewire.posts.posts', [
'posts' => Post::where('category_id', $this->cid)->orderBy('id', 'desc')->paginate(),
'categories' => Category::all(),
'tags' => Tag::all(),
]);
}public function store()
{
$this->validate([
'title' => 'required',
'content' => 'required',
'category' => 'required',
]);$post = Post::updateOrCreate(['id' => $this->post_id], [
'title' => $this->title,
'content' => $this->content,
'category_id' => intVal($this->category),
'author_id' => Auth::user()->id,
]);if (count($this->tagids) > 0) {
DB::table('post_tag')->where('post_id', $post->id)->delete();
foreach ($this->tagids as $tagid) {
DB::table('post_tag')->insert([
'post_id' => $post->id,
'tag_id' => intVal($tagid),
'created_at' => now(),
'updated_at' => now(),
]);
}
}
session()->flash('message', $this->post_id ? 'Post Updated Successfully.' : 'Post Created Successfully.');$this->closeModal();$this->resetInputFields();
}public function delete($id)
{
Post::find($id)->delete();
session()->flash('message', 'Post Deleted Successfully.');
}public function edit($id)
{
$post = Post::with('tags')->findOrFail($id);
$this->post_id = $id;
$this->title = $post->title;
$this->content = $post->content;
$this->category = $post->category_id;
$this->tagids = $post->tags->pluck('id');
$this->openModal();
}public function create()
{
$this->resetInputFields();
$this->openModal();
}public function openModal()
{
$this->isOpen = true;
}public function closeModal()
{
$this->isOpen = false;
}private function resetInputFields()
{
$this->title = '';
$this->content = '';
$this->category = null;
$this->tagids = null;
$this->post_id = '';
}
}

In the above code we are doing pagination as there might be many posts belonging to a category. To do so use Livewire\WithPagination then use paginate() method to get paginated records.

In the above code block we have used mount() method, we use mount() method to intercept parameters. To get the id of category from URL we will use this method.

This time we are passing posts, categories, and tags to view so we will pass these as an array in the second parameter while returning view.

Rest of the code is mostly repetative. So I am ignoring for now.

Now lets work on Posts. Posts page will look like this:

Once again run make:livewire as follows:

php artisan make:livewire Posts\\posts

Open app\Http\Livewire\Posts\Posts.php file and paste the following code:

<?php
namespace App\Http\Livewire\Posts;
use App\Models\Category;
use App\Models\Image;
use App\Models\Post;
use App\Models\Tag;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Str;
use Livewire\Component;
use Livewire\WithFileUploads;
use Livewire\WithPagination;class Posts extends Component
{
use WithPagination;
use WithFileUploads;
public $title, $content, $category, $post_id;
public $tagids = array();
public $photos = [];
public $isOpen = 0;public function render()
{
return view('livewire.posts.posts', [
'posts' => Post::orderBy('id', 'desc')->paginate(),
'categories' => Category::all(),
'tags' => Tag::all(),
]);
}public function store()
{
$this->validate([
'title' => 'required',
'content' => 'required',
'category' => 'required',
'photos.*' => 'image|max:1024',
]);// Update or Insert Post
$post = Post::updateOrCreate(['id' => $this->post_id], [
'title' => $this->title,
'content' => $this->content,
'category_id' => intVal($this->category),
'author_id' => Auth::user()->id,
]);// Image upload and store name in db
if (count($this->photos) > 0) {
Image::where('post_id', $post->id)->delete();
$counter = 0;
foreach ($this->photos as $photo) {
$storedImage = $photo->store('public/photos');
$featured = false;
if($counter == 0 ){
$featured = true;
}Image::create([
'url' => url('storage'. Str::substr($storedImage, 6)),

The above code follows the same pattern as previous codes. Here I am uploading multiple files. To upload file use Livewire\WithFileUploads. Read more here about Livewire file upload.

Open resources\views\livewire\posts\posts.blade.php and paste the following code:

<x-slot name="header">
<h2 class="font-semibold text-xl text-gray-800 leading-tight">
Posts
</h2>
</x-slot><div class="py-12">
<div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
<div class="bg-white overflow-hidden shadow-xl sm:rounded-lg px-4 py-4">
@if (session()->has('message'))
<div class="bg-teal-100 border-t-4 border-teal-500 rounded-b text-teal-900 px-4 py-3 shadow-md my-3"
role="alert">
<div class="flex">
<div>
<p class="text-sm">{{ session('message') }}</p>
</div>
</div>
</div>
@endif
@if (Request::getPathInfo() == '/dashboard/posts')
<button wire:click="create()" class="inline-flex items-center px-4 py-2 my-3 bg-gray-800 border border-transparent rounded-md font-semibold text-xs text-white uppercase tracking-widest hover:bg-gray-700 active:bg-gray-900 focus:outline-none focus:border-gray-900 focus:shadow-outline-gray disabled:opacity-25 transition ease-in-out duration-150">

</div>
<div class="px-6 pt-4 pb-2">

</div>
</div>
@endforeach

<div class="py-4">

Then create file resources\views\livewire\posts\create.blade.php to be used as model for post create and edit and paste the following code:

To show single post create file app\Http\Livewire\Posts\Post.php and paste the following code:

<?php
namespace App\Http\Livewire\Posts;
use App\Models\Post as PostModel;
use Livewire\Component;class Post extends Component
{
public $post;
public function mount($id)
{
$this->post = PostModel::with(['author', 'comments', 'category', 'images', 'videos', 'tags'])->find($id);
}public function render()
{
return view('livewire.posts.post');
}
}

Now create view for the single post resources\views\livewire\posts\post.blade.php and paste the following code:

<x-slot name="header">
<h2 class="font-semibold text-xl text-gray-800 leading-tight">

This completes Categories and Posts. Now Tags and navigation menus are remaining. I will update that here very soon.

The source code is available at Github for you to refer to.
