Thank you, everyone. I think it's the worst decision I've made in my life, but I'm here, so we can start. There was a presentation about Sidekiq, and a question came up about Sidekiq batches. I remembered that I used them once in all my four years of experience, and I can share with you how you can do it.
00:00:27.760
First, we need the source for our work. In my case, it was a file containing around a thousand rows that needed to be executed with some comments, and we needed results. If we don't approach this in a synchronous manner, we'll face issues; our business will suffer. Therefore, we tried to optimize it by using Sidekiq and batches. So, we parsed our file, and for each row, we put a worker inside the batch. For example, if we have 100 rows, we end up with 100 workers. I designed a unique identifier for each row which helped identify the sequence.
00:01:02.480
For this example, the unique ID consisted of the time, name, and a sequence number, which I'll start with one. When I executed the command, the results were stored in Redis under a key representing the sequence number. After finishing all my 100 jobs, I would have 100 results in Redis. Moreover, I set a callback for the batch, which recognized the unique source name. In the callback, I created another worker to gather results knowing we had 100 rows in our file. When all jobs were finished, this last worker would read from Redis the source name and the sequence numbers.
00:03:08.400
Knowing the sequence, I gathered the results from all the jobs and created a new result file. I included the source parameters, my comments on them, and the results. The sequences in this result file matched those in the source file, and the business was happy. That's all for now. I hope nobody has questions. However, one question that has come up is how fast an RTMS rocket needs to move to escape Earth's atmosphere and reach a stable orbit.
00:04:42.160
Honestly, I don't care how to calculate this because I'm assuming that everyone here is a fan of Kerbal Space Program. But it's fascinating to think about how when asked how fast you were going, nobody flinches, even though that perspective is quite modern. Looking back at the time of Aristotle and Socrates, they worked with mathematics that was primarily about geometry and trigonometry, believing the world was perfect. They didn’t concern themselves with the real world and how math applied to it.
00:05:02.560
They couldn't explain momentum or how things move, perceiving it as merely a side effect. However, things changed thanks to thinkers like Galileo and Descartes. Galileo realized that time is a unit of measurement, which was an explicit understanding that had not been established before him. Descartes developed the Cartesian coordinate system, merging geometry and algebra into one field. This laid the foundation for modern mathematics, leading to the invention of calculus by Newton and Leibniz. The crucial aspect here is time; it became understood as a measurable unit. This is essential because until that point, the concept of speed was almost science fiction, while now it’s commonplace, as we often think of it in the context of speeding tickets rather than reinventing mathematics.
00:06:54.960
In considering this, I believe we need to evolve our understanding, much like how mathematical advances spurred future generations. When listening to talks by experts, I urge everyone to think not just about the current technology or trends but about the essence behind them and how these concepts can be applied in new ways. My goal is to inspire people to think critically about their work and foster new ideas that will lead to future breakthroughs in technology, similar to those seen in the past.
00:09:16.480
My name is Andrew, and I work for an outsourced company where I serve as a main developer or sometimes a tech lead, depending on the project. In outsourced companies, projects and teams often vary. Thus, mentoring junior developers can become part of the job, and I enjoy it greatly. I believe mentoring offers several benefits, including keeping my skills sharp and helping develop engineers within our company, ultimately making our company better.
00:10:02.400
Additionally, mentoring aids in community growth. With discussions around whether Ruby is dying, we must focus on the positive: we are creating more engineers. I also find fulfillment in mentoring refugees and immigrants in my free time, hoping to inspire others to do the same. The key for me in all volunteering efforts is identifying what motivates you personally.
00:12:03.840
Now, regarding the ongoing debate about Ruby's future, I wonder why this question of Ruby dying persists. It seems many companies are transitioning away from Ruby due to performance issues, turning to alternatives like JRuby or newer languages such as Rust. While I understand why some companies make this move, I believe we should support Ruby and not abandon it. Many people I know have switched to Elixir or other languages, but I’ve seen no significant outflow of Ruby developers recently, reinforcing the notion that Ruby's community is still vibrant.
00:14:06.080
When you analyze the data published each year about programming languages, you can observe that while Ruby's popularity might be slower compared to languages like Python or JavaScript, the number of Ruby developers has been increasing, not declining. Although the growth rate is slower, it’s essential to recognize that we shouldn’t compete with Python, given its diverse applications beyond web development. We have a strong community and should focus on nurturing that strength rather than lamenting our standing compared to other languages.
00:20:15.840
Let’s move on to talking about configuration states in Ruby. Nowadays, we have various options to manage configurations, yet many of those require your code to be aware of the infrastructure. There's a lot of room for improvement. The noa config library takes a different approach, allowing you to define configuration through classes without the consistency issues related to where your configuration is stored.
00:20:34.680
In this way, the infrastructure doesn't bleed into your codebase. However, while I appreciate the concept, I find the syntax not very user-friendly. Thus, I thought about applying similar ideas while adopting a more intuitive syntax, which led to the development of a new configuration method that aligns with the principles of dry struct, allowing easy definitions and modular loaders that can fetch values from various sources. This library is still in development but shows promise. Thank you for your attention.
00:22:00.000
Thank you! That's all from me!
