I see in the last days quite a big move of people from Ruby community joining Blue Sky. 
Blue Sky offers some interesting automation options via their architecture and API thus this could be the beginning of seeing back tutorials about writing a Ruby script to post on social media.

It is something exciting about running a script on your local machine and publishing something on the internet that was destroyed once Twitter started putting a price on their API. 

So here are three things I recommend to keep the sparkle that is happening this days for people that just joined: 

1. Add a picture and description to your profile 

I know that 10-15 years ago when social media first appeared it was ok to just join, but to start the networking effect (people following other people) I think having a picture (could be an avatar, graphic) and a short sentence about you is a great way to invite people to join.

2. Make your first post

Make a first post on the platform. I am sure you have something to say. Specifically if you are from Ruby community say something about Ruby. Here are some ideas about what you can post: 

• Just say "Hello"
• Publish a short intro about yourself: who you are, what are you working on, where do you live ... whatever you feel like sharing
• Write something about what you are currently working on
• Publish a link to an interesting article that you read this week. Bonus points if it is about Ruby/Rails or something related

3. Engage with other people

To keep the community going it is important to engage with people posting there.
Try to be helpful and reply to people posting.

I suggest to adopt the mindset "A rising tide lift all boats" and so help other people get better, find their answers. Share something constructively. Engage in building and creating. Comment something that you think will add value.

If you are posting already code samples, code screenshots or technical articles on other platforms please try to post them here also.

Because this platform is somehow at the beginning and now people from Ruby community are starting to be more active there, this could be your chance to share your thoughts here and be read by important people in the community.

This is a post that I will update this weekend with all the steps I am doing to move the newsletter.

---

05 October 2024 - 07:00 AM
First thing, I put the newsletter on private on Substack:

---

05 October 2024 - 10:00 AM
Second, I need to manually unsubscribe people who unsubscribed from Substack between the first import (20 September) and now. I seem not to have found a way to delete all subscribers in Beehiiv and start from scratch.

I could have deleted everything and started from scratch, but I also have some imports running so I don't want to force my newsletter into a state where it has some errors (like I delete some subscribers and the imports are still running). Maybe it is just my developer brain that thinks about this :)

---

05 October 2024 - 11:56 AM
Third thing, I did a small PR to change how citation is displayed in our internal source:

A shoutout to Kevin Chambers, who quickly replied to all my questions, good or stupid, that I had. This helped me a lot with the migration.

---

05 October 2024 18:35 (06:35 PM)
After finalizing all the imports, I noticed there is a difference in the total number of subscribers between Beehiiv and Substack: Beehiiv has less than Substack.

I wrote a short script in Ruby to compare them and found: 

Total missing lines: 118

🙃 - I am not sure why this difference exists.

I tried to import them manually, but Beehiiv reports back 0 imported. They are not found to be imported into the interface.

---

06 October 2024 - 00:04 AM
A ticket has been created after Kevin tried to help me debug this. We will probably have to consider announcing that some people will not receive the newsletter until this issue is solved.

---

06 October 2024 - 06:00 AM
I continue to edit the newsletter and add content to it

The editor is super good. I discovered that it allows markdown so I will do some PRs to my Rails app where I have the content and create the citations to generate some markdown ready to copy/paste in the editor.

I also want to play a bit with the API - the first thing I think is probably an integration between LemonSqueezy and updating the subscriber status on Beehiiv if possible.  I will probably use https://developers.beehiiv.com/api-reference/subscriptions/put to add a custom field to the subscription and then create a dynamic segment from that. I will figure this out next week. But I am pretty excited to have an API and thus will be able to automate more stuff.

Just figured out a new task for today: export the paying subscribers in LemonSqueezy and cross-reference them with the subscribers marked as paid in Beehiiiv.

---

07 October 2024 - 06:30
I discovered that by default, Beehiiv does not have an RSS feed via a question on Ruby.social, where someone noticed that the newsletter feed is gone.

Found a way to generate one via Settings -> Publication -> RSS Feed, but the generated URL is not good: https://rss.beehiiv.com/feeds/X67SCnFvlW.xml

I haven't been able to find a way to add an RSS feed button to the main website using the website builder.

I made a quick fix to https://feed.newsletter.shortruby.com and this will be the way to go for anyone that wants to add the newsletter feed. This reinforces my idea that whatever you build you should own the URLs. It allows you to add features that are missing or fix bugs even if the platform does not have support for them. 

---

8 October 2024 06:23 
Beehiiv support reviewed all the non-imported email addresses and confirmed that all of them are invalid. And I agree that it does not make any sense to import them. I don’t want to have subscribers just for numbers but I want people that are reading the newsletter. 

So this issue is solved!

Continuing my updates about the migration of shortrubynews to Beehiiv, at the end of the day today or tomorrow morning (Saturday morning), I will put the newsletter on Substack on private. This means any new subscription needs to be approved and the purpose is to ensure there are no new subscriptions to the newsletter during the migration. 

Next on my list is to add a visible notice in the next edition with a clear Unsubscribe button just in case someone unsubscribed during the export/import but is still imported as active. 

The new newsletter layout will take a couple of iterations to work, but I look forward to customizing it and making it a bit more readable.

This move to Beehiiv opens multiple possibilities: 

• Maybe start doing the 3 Ruby Links project as a weekly project under the umbrella of 
• They have an API, so maybe I can automate the content editing more, shorten the time spent arranging items on the page, and do proper citations. 
• The possibility of having more ads or offering boosts for other IT-related newsletters

In general, this move will help make the newsletter sustainable and, in the long run, afford to pay someone to fully help with content editing. It also opens up the possibility to focus can of automation and allow more time to be spent on better curation. 

I am currently migrating Short Ruby Newsletter to Beehiiv. 

I hope to finalize the move by Sunday, 6 October, so the next edition can be sent via Beehiiv. 

What is keeping me busy with this migration?

Roadblock: The imported content does not have image captions

The current roadblock is that the migration of old content did not import the image captions, where I was writing the citation ("Source: @name") with a link to the post in the screenshot.

I wrote to their support, and it seems like this is not supported so far.

So it seems my only decision is to manually add all those citations - which is a lot of work: there are 108 editions (and around 160 posts, because I experimented in the early days with various formats).

Unclear: What should I do with the content on Substack?

Once the migration is finished, what should I do with the content on Substack?

First, the content cannot remain there as there will be duplicates with the one being hosted on Beehiiv.

After the switch the main domain: newsletter.shortruby.com will point to Beehiiv and the Substack one will remain at shortruby.substack.com

Also, the subscribers should only be in a single place, so the list of subscribers on Substack should be deleted. 

I am thinking about a couple of options:

1. Remove all the posts and unsubscribe everyone on Substack, but keep the subdomain there with a message stating that the newsletter is now hosted there.

2. Close the publication: this will delete all content and all subscribers

Over the weekend I have to take a decision also about this. 

How do you know if a git commit message is good?

If you can browse your git history and understand why those changes were made and why/how that technical decision happened without needing to refer to tickets, issues, or requirements, then you likely have an excellent git history.

If your git history looks like:

    Add new tag formats to improve the speed of tagging

    This commit introduces new tag formats in the TagTypeMap and updates
    ContentTypeIdentifier tests for compatibility.

    These changes ensure that the ContentTypeIdentifier can correctly
    identify content types using the new tag formats, maintaining
    the system's flexibility and reliability.

    Why these changes?

    (1) We want to allow users to tag content using shorter tags
        eg: `stype` instead of `section:type`

    (2) Automatically fix typos in tag formats:
        eg: typing `a` instead of `s` in `s:type` => `a:type`

    (3) Duplicate tag letter replaces `:`
        eg: `aatype` is the same as `a:type`
            `sstype` is the same as `s:type`

    Changes:

    1. Updated TagTypeMap to include new formats:

    - 's:type' (e.g., 'a:code', 'a:article')
    - 'stype' (e.g., 'scode', 'sarticle')
    - 'sstype' (e.g., 'sscode', 'sstarticle')
    - 'a:type' (e.g., 'a:code', 'a:article')
    - 'aatype' (e.g., 'aacode', 'aaarticle')
    - 'Aatype' (e.g., 'Aacode', 'Aaarticle')

    2. Updated ContentTypeIdentifier tests to cover new tag formats
    for all existing content types:

    - Code, Articles, Videos, Library, Newsletter, Podcasts
    - Related, Community, Events, Books, Launch, Slides

A better example

Here is an example of a git commit message shared by Zlatko Alomerovic via Linkedin. The message is written by Jean Boussier (@byroot) in a commit for Rails  and it looks like this (here is just the first part of it)

The full message looks like this: 

commit 8c7e69b79b63a88a170a9b9004a906db00161a3b
Author: Jean Boussier 
Date:   Mon Jan 8 18:43:37 2024 +0100

    Optimize Hash\#stringify_keys

    Using Symbol\#name allows to hit two birds with one stone.

    First it will return a pre-existing string, so will save
    one allocation per key.

    Second, that string will be already interned, so it will
    save the internal `Hash` implementation the work of looking
    up the interned strings table to deduplicate the key.

How to start a new Rails project using Rails 8.0.0.beta1

gem install -v 8.0.0.beta1 rails
rails _8.0.0.beta1_ new my_new_app_on_rails8_beta

How to start a new Rails project with Rails main: 

rails new my_app_on_rails_main --main

I wrote a longer article about this here, but with examples from Rails 7.1.0.beta1

I am not at Rails World, and I have huge FOMO at home. I look at almost all the people going there and already have a great time even before the conference starts. 

Enjoy the conference and make some new friends!

With this occasion, I'd like to invite you all to share/post online what you are learning during the conference.  It would be good for the community to post live updates on social media during all conferences. 

Here’s the structure of a good social media post:

1. Take a screenshot of a slide, ensuring the speaker is included.
2. Highlight the most important idea the speaker mentioned
3. Add your own thoughts about it.
4. Publish the post, then reply with the next interesting point from the presentation.

In case you want to see some examples, I did something like this from my own account during EuRuKo (see a list of posts here) and did the same from the Friendlyrb account on Twitter and Mastodon during Friendly.rb conference. 

I got very good feedback about doing this kind of live posting. 

I know that usually all videos and slides are posted online, but creating a buzz during the conference and sharing the ideas that YOU find interesting is also an important contribution. 
It helps show how active our community is and how many ideas are shared. 

Later on, the series of posts that you shared could be transformed into a blog post about how it was at that conference, and in the process, you will get the side effect of doing a recap of what you learned from that experience. 

Happy #RailsWorld!
