An interesting article was shared in our chat yesterday.
This is a summary of the analysis of AI's influence on code quality. Some excerpts:
> The data strongly correlates “using Copilot” with “mistake code” being pushed to the repository more frequently.
> The 17% decrease in “move” operations when compared to 2021 hints at
the built-in trait of AI assistants to discourage code reuse. Instead of
refactoring and working to DRY (“Don’t Repeat Yourself”) code, they offer a one-keystroke templation to repeat existing code.
> Especially next to the decrease in “moved code,” the 11% increase in the proportion of duplicated code confirms the drop in overall code quality in 2023 when compared to 2021.
And my favorite one:
> In the absence of a CTO or VP of Engineering who actively schedules time to reduce “tech debt,” “copy/pasted code” often never gets consolidated into the appropriate component libraries.
Although, I saw this even before AI.

Today I want to share with 2 articles from a guy who knows a thing or two about SLOs - Alex Ewerlöf.
- Heterogeneous SLI vs Homogeneous SLI in which he argues on type of events used for SLI and how to reason about them
- SLO: Elastic vs Datadog vs Grafana in which he compares SLO offerings from 3 major observability providers

Recently I was on a meetup, where a guy from Grafana Labs presented Beyla - their new eBPF application instrumentation solution. It's an interesting concept, that allows one to "instrument" an app without actually changing the code, but by intercepting system calls using eBPF.
What can I say: it's a cool concept. Here, Netflix describes how they use eBPF to monitor noisy neighbors. Yet, in case of Netflix it involves a lot of custom code, ofc.

My German teacher is also a volunteer. Together with his buddies, he constantly raises money for ongoing requests from the Ukrainian defenders.

AI agents invade observability: snake oil or the future of SRE?.
We got from "measure everything" by Twitter to "monitor only what matters" by Honeycomb. Yet, alert fatigue, convoluted dashboards, and garbage metrics are still an issue today.
Could AI solve this? We simply don't know yet. The linked article speculates on this topic: is AI in Observability just another marketing trick or something that could help engineers to solve issues faster or more importantly prevent those issues all together.

A friend of mine is raising funds for drones and other equipment for the International Legion of Ukraine.

Currently, 60k out of 75k is there, so let's help him to reach the goal!

I have surely seen similar projects before, but it means that the idea is compelling.
Cyphernetes is a query language for Kubernetes inspired by Cypher (Neo4j query language).
It’s open source and available on GitHub.
So, the idea of being able to use some more or less generic query language to check your infrastructure is there. There are different implementations and none of them is a “golden standard” today. Yet, let’s see. Maybe, one day we would have one.

Your company needs Junior devs.
This article reminds me of when a long time ago a senior manager was doing a presentation which had a tweet: "A team of senior engineers without juniors is just a team of engineers". This manager tried to make a point of how egalitarian we are because the team is so senior, but was quickly corrected by one of the engineers that they missed the point of the original tweet completely.
I really like how this article shifts the perspective of a senior developer:
companies, they argue, see the “assembly line” of a knowledge firm. They see the outputs: KPIs, OKRs, Quarterly results. If you only think in terms of the assembly line, you will only seek units of input that increase those outputs (ie expert employees that ‘hit the ground running’ to churn out higher metrics).
...
employees come prepared with that Socratic dialog: to ask dumb questions and seek their answers. Often, it turns out, experts – through ego or blindness - don’t see obvious solutions. They don’t question tacit assumptions. Juniors on the other hand eagerly crash into, and sometimes through, problems seniors have convinced themselves are too hard. Juniors try “dumb” things that often fail, but sometimes show how blinded experts have become from their long held assumptions.
The main point is that people who ask many questions (juniors) foster the culture of curiosity and psychological safety, while even for some more senior folks it might be too shameful to ask questions that "should" be "obvious" for those with many years in the industry. Therefore, without a culture of curiosity, many problems will be swiped under the rug.
And yet, this is way too hard these days for junior folks to find a job. Trading short-term gains for the cost of long-term consequences. This has never ever happened to humanity before!

Why Cutting Costs is Expensive: How $9/Hour Software Engineers Cost Boeing Billions.
This is a quite famous story about Boeings 737-Max falling down because of a software bug.
A friend of mine was closely following this story from even before the tragedies. Since it all started with Airbus blowing Boeing out of the water.
Anyway, let this article be a reminder to you that software engineering is not just for cat videos these days.

Since I’m a bit busy this week, I cannot really bring too many articles to you this week.
Every time this happens, Humble Bundle comes to my rescue :D
So, today I want to share a bundle of courses about cloud by Packt.
You can get it for a bit more than $20 for the next 11 days.

Some people know that I'm not a fan of Python. Yet, I have to tolerate it because it is objectively one of the most popular and widespread programming languages.
So, here is an article about asynchronous code in Python.
Enjoy!
