How to Upgrade Your Ghost Blog via Command Line

Welcome to "Continuous Improvement," the podcast where we explore tips, tricks, and strategies for improving and optimizing various aspects of our lives. I'm your host, Victor, and in today's episode, we're going to discuss how to upgrade your Ghost blog to the latest version. So if you're a Ghost blog owner and want to make sure you have all the latest features and bug fixes, this episode is for you.

Before we dive into the steps, make sure you have access to your Ghost blog directory. This is where all your Ghost files are stored. Once you're ready, let's get started!

Step 1 is to navigate to your Ghost blog directory. In your terminal, change the directory to the path where your Ghost blog is installed. For example, if your blog is located at /var/www, you can use the command:

cd /var/www

Great! Now that we're in the right directory, step 2 is to download the latest version of Ghost using the wget command. You can find the current version on the official Ghost website at https://ghost.org/download/. Once you have the download link, use wget followed by the link to download the latest version.

Awesome! Now that we have the latest version of Ghost downloaded, let's move on to step 3. In this step, we need to remove the old core code. Use the following command to delete the old core directory:

rm -rf ghost/core

We're making progress! Step 4 is all about unzipping the downloaded file into the Ghost directory. Use the command unzip -uo ghost-X.X.X.zip -d ghost, where X.X.X represents the version number you downloaded. This will extract the files and overwrite any existing ones.

Moving on to step 5, we need to update the ownership and permissions for the newly added Ghost files. This helps ensure everything works smoothly. Use the command chown -R ghost:ghost ghost/ to update the ownership.

Step 6 is an important one. We need to install new dependencies for the upgraded Ghost version. Navigate back to your Ghost directory using cd /var/www/ghost and run npm install to install the new dependencies.

Fantastic! We're almost there. In step 7, it's time to restart your Ghost blog to complete the upgrade process. Use the command pm2 restart ghost if you're using pm2. If not, you can try service ghost start instead.

And there you have it! Your Ghost blog should now be successfully upgraded to the latest version. Remember, keeping your blog up to date ensures you have access to all the latest features and bug fixes.

That brings us to the end of this episode of "Continuous Improvement." I hope you found these steps helpful in upgrading your Ghost blog. If you have any questions or suggestions for future episodes, feel free to reach out to me. Until next time, keep improving and optimizing!

How to Fix Ruby Gems Permission Error on Mac OS X Yosemite

The Problem

While trying to install a gem on Mac OS X Yosemite, I encountered the following error:

ERROR: While executing gem … (Gem::FilePermissionError) You don’t have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

The Solution

Step 1: Install Rbenv

To start, you'll need to install Rbenv and Ruby-build:

brew install rbenv ruby-build

Next, add Rbenv to ~/.zshrc so it starts automatically:

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(rbenv init -)"' >> ~/.zshrc

Note: If you are not using Zsh, modify your ~/.bash_profile instead of ~/.zshrc.

Step 2: Restart Your Shell

Close your terminal and reopen it to apply the changes.

Step 3: Install Ruby, Set Global Version, and Rehash

Now, install Ruby and set it as your global Ruby version:

rbenv install 2.0.0-p247
rbenv global 2.0.0-p247
rbenv rehash

Step 4: Install Gems as Usual

You can now proceed to install gems without encountering permission issues.

gem install [gem-name]

Your gem should now install successfully!

Step 1 is to install Rbenv and Ruby-build. Open your terminal and enter the following command: "brew install rbenv ruby-build". This will install the necessary tools.

If you are using a different shell, such as Bash, modify your ~/.bash_profile with the same commands.

Step 2 requires you to restart your shell. Close your terminal completely and reopen it to apply the changes we made.

In Step 3, we'll install Ruby, set it as your global version, and rehash. Enter the following commands in your terminal: "rbenv install 2.0.0-p247" to install Ruby, "rbenv global 2.0.0-p247" to set it as the global version, and "rbenv rehash" to update the Ruby environment.

Great! Now we're ready for Step 4. You can now proceed to install gems without encountering any permission issues. Simply use the command "gem install [gem-name]" to install your desired gem.

Survival Tips for Non-Korean Speakers in Busan and Vicinity

Aleumdaun! This is how Koreans describe something as "lovely." They often use this phrase to talk about the scenic beauty of Busan, Gyeongju, and Jinhae, particularly in the spring when cherry blossoms are in full bloom.

Who doesn't love traveling? Korea is an under-explored country where most visitors usually don't venture beyond Seoul. Each of us has our own travel priorities and preferences. Personally, I love spontaneous travel, as it provides a break from my regular work schedule. It’s exhilarating to put myself in unfamiliar situations, where I don’t know the language or even have internet on my iPhone. It’s a daring step out of my comfort zone.

Here are some survival tips for non-Korean speakers visiting Busan:

Make New Friends

While staying in a guesthouse instead of a hotel, I met a savvy businessman, a talented doctor, and a lovely ajumma (Korean auntie). Though my limited Korean skills make verbal communication challenging with those who don’t speak English, remember that two-thirds of human interaction is nonverbal. A friendly smile and a warm greeting are universal. I spent an entire afternoon conversing through pictures and gestures. Koreans have a knack for turning strangers into friends. They are not only polite but also some of the kindest people I’ve met. To stay connected, consider downloading the Kakao Talk app.

Get a High-Level Overview

Before exploring, get an overview of the city to avoid getting lost. Busan Tower, at 120 meters high, provides a splendid panorama. From its top deck, you'll get a 360-degree view of Busan, including the magnificent Gwangan Bridge.

Relax and Enjoy

Haeundae Beach is extraordinary, to say the least. The sight of the ocean will take your breath away. Nearby, you'll find attractions like Oryukdo Island, APEC Naru Park, and an aquarium. If you tire of walking, coffee shops like TwoSome Place, Tom n Tom, or Caffeine Gurunaru offer cozy retreats. Also, don't miss SpaLand Centum City, located in the world’s largest department store, Shinsegae. It’s the perfect place to unwind.

Keep an Open Mind

Busan's charm isn't just in its tourist spots; even a simple walk down the streets is captivating. From pig guts to pancakes, the city’s markets offer a unique blend of tradition and modernity. For delicious street food, head to the Busan International Film Festival (BIFF) square. If you’re a shopaholic, you’ll love the underground mall at Seomyeon and the bustling area near Nampo station. Also, the Jagalchi Fish Market is a must-visit for seafood lovers.

Learn About the Culture

Gyeongju, located north of Busan, was the capital of the Silla dynasty for nearly a thousand years. It's a heritage site featuring grassy tombs of ancient royalty. Bulguksa Temple is often at the top of visitors' lists. It costs only 4,000 won for entry into this World Heritage site.

Enjoy Breathtaking Scenery

Every spring, Jinhae-gu, west of Busan, hosts a ten-day cherry blossom festival. The 1.5-kilometer long tunnels of flowers are a must-see. When a gust of wind makes the petals fall, it's a surreal and romantic scene.

So, grab your passport and join me on a trip to Busan for an exciting weekend getaway! Hopefully, this article inspires you to explore Korea and immerse yourself in its culture. To be honest, my body may have returned to the office, but my soul is still in Korea. Add me to your list of travel companions; I'm excited to discover more beautiful places and share them with you. Kamsa-Hamnida, which is the Korean way to say a heartfelt thank you.
