Hi fellow rubyists!

I currently consume a quite big JSON object (that has multiple levels) that I get via an OData2 response.

I initially looked at struct, but this means defining everything and values can be altered. So I decided to use Data instead since it cant be altered afterwards but here I now ended up having multiple Data objects for each level defining dozens of fields...

I know there is OpenStruct left, but this is deprecated and has a bad reputation somehow.

How would you work with an JSON based datasource that has >10 subobjects with > 100 fields that are quite stable (no field is going to get removed, only new ones may come) without the need to do too much work on duplicating everything. I still want to access the data like Object.subobject.data instead of json["Object"]["subobject"]["data"] since the paranthesis gets tedious over time

You have invested a lot of money in your application, but do you have a complete understanding of the risks within your code?

If you were looking to buy a car, you want to be aware of any risks before you spend your hard-earned money. It is worth the investment to have a qualified mechanic inspect the engine.

It’s the same scenario before engaging in further development. Understanding your application’s risks will save you a lot of money and development time in the future.

Outsourcing for a fresh perspective on your application is not about distrusting your in-house development team or provider. It's about recognising their effort if they are doing an incredible job, as well as giving them an opportunity to learn and improve. The development world moves fast, so the key objective is to support and educate the existing development team. The more eyes on the code the better.

reinteractive’s Application Review is highly valuable if you are in any of the following situations:

1. You have a Rails application with no or only a few developers working on it
2. Development was completed by another software firm and you need to verify the quality of the app
3. You are experiencing performance issues.
4. You need to determine the risk profile of your investment.
5. It is important to know if you have any security issues within your application.
6. You want to develop new features and need a clear picture of your app as a base line.
7. You want a sense of the technical debt within your application and what may be required to clean it up.

I am contacted by businesses for various reasons.

• They want to upgrade their app with new features.
• There are bugs within the app that aren’t resolving, and they need an expert opinion.
• They want to bring in developers for a specific product development phase, bolstering their in-house team.

In every case, I advise first to get an App Review done on their existing application before anything further is done. It is the industry leading analysis service for Ruby on Rails applications.

Back to the analogy of treating your application as you would a car. You don’t just let your car run without regular inspections and services. In the same way, to keep your application running well and servicing your customers and business needs, you need it reviewed for quality, performance and security.

reinteractive is Australia's largest Ruby on Rails development firm. Lead by our Founder, Mikel Lindsaar, author of the Mail gem and the only Australian authorised to make changes to the Rails code base, we are a team of top Rails developers and designers. Over 2 million businesses around the world use software developed by reinteractive. We leverage this skill to deliver a top-quality app review. We dive in and review your code with a 9-point review service.

Technical debt is a real issue. Sometimes a developer, instead of using the best approach which will take longer, will choose the quick and easy solution when coding, especially when a deadline for launch is looming. It is totally understandable, and it may be needed to get your application up and running right now. But such a path also causes technical debt – similar to a financial debt. It costs money to rework it and the longer it is left, the more it can cost. If you want your application to be healthy for years to come, it is something that needs to be addressed as quickly as possible.

When we do an App Review, we provide you with a written summary with essential information around - security,
- performance,
- risk management
- and a summary of quality and
- technical debt within your application.
This lets you know exactly where everything stands. From there, you and your team can make the necessary choices based on facts. The last thing you want is to get into major feature development, hire a developer to do it, only to find the work becomes complicated because of technical debt already existing in your application.

And the good thing is an App Review is at an affordable price point making it a no-brainer essential service to check on your application.

I have already been helping clients with reviews of their applications. It gives them peace of mind knowing that major issues within their app have been identified and gives them a path forward to resolving them.

I am happy to talk, answer any question you have. Send me an email or give me a call AUS +61 2 8019 7252 | USA +1 415 745 3250.

Good Morning All!

I've been on a programming journey this year, learning Python as my first language and delving into AI Development with some fun little projects. I wanted to use it from SysAdmin tasks at my job, but I mostly use Bash and Powershell as our two systems are so separated there's no need for a universal tool.

Anyways, I'm now studying Ruby and I'm going through a course on Udemy. I feel like it'll be relatively easy to pick up once I understand the different syntax, and I wanna get the Ruby Silver cert for my own gratification.

When I learned python, I made a TON of projects. Everything from a subnet calculator to a full-blown AI with emotions, memory, reinforced learning, TTS/STT etc. I want to practice ruby in the same way, and my question is do y'all have any suggestions, and would it be a good idea to go back through my Python projects, and recreate them in Ruby?

Looking forward to this journey, though taking college classes, learning Ruby, and studying for my S+ is making my brain a little swamped lol. Thanks y'all!

Hi All! We just published a guide on using Azure SDK with Ruby, even though it’s not officially supported. It’s a straightforward workaround if you’re looking to connect Azure with Ruby projects. Check it out and let us know what you think! link 🚀

JavaScript: Using the Clipboard API to copy credentials to the clipboard.
Browser: Firefox.

Localhost***

Clipboard API usage:
This code "works", but it's not what i want it to do, i just want to copy the credentials to the clipboard (later when it works, i will be doing some changes). But it just works if i do it with an URL. 
I have a button in my app that, when clicked, generates a URL (just tested whatever website)  with the credentials and attempts to copy this URL to the clipboard. Here's the JavaScript I am using:
`
`document.querySelectorAll(".share-credentials-btn").forEach(function(button) {
  button.addEventListener("click", function() {
    const unlocked = button.getAttribute("data-unlocked") === 'true';
    if (unlocked) {
      const username = button.getAttribute("data-username");
      const password = button.getAttribute("data-password");

      // Generate the URL to share credentials
      const passwordPusherLink = `https://www.passwordstore.com/push?username=${encodeURIComponent(username)}&password=${encodeURIComponent(password)}`;
      
      // Try to copy the URL to the clipboard
      navigator.clipboard.writeText(passwordPusherLink).then(function() {
        alert("Credentials copied to clipboard!");
      }).catch(function(error) {
        alert("Error copying credentials: " + error);
      });

      // Optionally open the link in a new window
      window.open(passwordPusherLink, "_blank");
    } else {
      alert("Unlock the credentials to share them.");
    }
  });
});`

4th stage interview, 2nd coding challenge (first one was in js). Expected completion time: 4 hours, including cloud deployment. Build and style single page with a table of users and a form to add those users via Ajax. "Frontend" must be built with bootstrap and jQuery, none of which I have used in the past 10 years. No css preprocessors or js pipeline, no virtual/docker environment.

Is it just me, or is this getting absolutely riddiculus?

I wrote this article about how the current garbage collection algorithm works in ruby. It would be great to get some feedback from the community on what they think about it :)

The open source engine indexes your memes by their visual content and text, making them easily searchable. Auto generate or manually create descriptions for your memes and tag them for easy recovery.

Find your funny fast, then drag & drop recovered meme(s) into any messager.

Note: local install requires >= 7gb of storage due to the size of AI model weights. It consists of three docker containers - the app, postgres db, and meme description generator.

Rails is a fantastic framework for building / iterating on "AI-powered" apps like this one.

See the project here 👉 https://github.com/neonwatty/meme_search

Uses gems like nieghbor, informers, and pgvector under the hood. As well as local calls to moondream, a "tiny" vision language model.

What are the weirdest and most obscure operators and special character syntax features in the Ruby programming language? Gimme your worst. I know there are a lot of dusty corners in Ruby.

For example, someone just told me about the string freeze/unfreeze modifiers (still not sure what to make of them):

> three = -"3"
=> "3"
> three.frozen?
=> true

> one = "1"
=> "1"
> one.frozen?
=> false
> one.freeze
=> "1"
> one.frozen?
=> true
> two = +one
=> "1"
> one.frozen?
=> true
> two.frozen?
=> false
> one.object_id
=> 360
> two.object_id
=> 380

Another favorite is Percent Notation because you can end up with some wacky statements:

> %=Jurassic Park=
=> "Jurassic Park"
> % Ghostbusters 
=> "Ghostbusters"
> %=what===%?what?
=> true

I've upgraded my Rails apps from using Ruby 2.6 to Ruby 3.3.5. I use DigitalOcean droplets, compiling Ruby from source - but my web app was crawling.

So I ran benchmarks on Ruby itself. I keep getting dismal results with Ruby 3.3.5 vs my old Ruby 2.6.10 server when benchmarking Ruby itself.

Ruby 3.2.6 is about 2.5x slower and 3.3.5 is about 3x slower.

I have tried spinning up many servers (DigitalOcean droplets), with jemalloc, without jemalloc, and I cannot get decent numbers for Ruby 3.

Any insight here?

Hi,

Can someone suggest a resource to learn to build terminal UI for a Ruby app? Usually I use Hanami or Roda for web apps, I used to code with Shoes for desktops, but I'd really like to create a terminal app as well that would still be appealing even though being old school.🙂
