Amazing Julia Evans posts about the things she missed in Go.

This is kinda a promotion of the book "100 Go Mistakes and How to Avoid Them" and you know what, now I want to read it!

P.S. Unfortunately, I don't have a chance to write much in Go lately, which makes me sad. Maybe, it will push me towards creating some side-projects, probably, someday, maybe 😭

​​Happy Independence Day, cats!

As you know, freedom never comes for free. So, the best way to celebrate this day is to make a donation to your charity of choice.

Here the list of charities I link to almost every post

Also, I would like to remind you about fundraisers from our friends at:

- UkrOps Club
- UA DevOps

I skipped the newsletter today, because there were not that many posts on the channel, TBH.

So, as an apology, here is a brief reminder from Google on why heroism is bad.

A very nice collection of books on software architecture by O’Reilly.

As usual, you can pay different amount to unlock various number of books.

The Senior Engineer Illusion: What I Thought vs. What I Learned is an article about one could have regarding the day-to-day routine of their more senior colleagues.

Ofc, many things may sound familiar to you personally, but never forget that there are less experienced peers in the industry for whom this information may be useful.

P.S. I didn't like some word choices of this article, but overall it's Ok.

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!

Sehr geehrte Damen und Herren,

Ich möchte gerne Ihren eine neue Cloud Alternative vorstellen.

European alternative to AWS, Azure and Google was born inside Lidl

P.S. АТБ Cloud: when?

​​For today’s Donations Monday, I would like to share with you an initiative from Come Back Alive - “Dronefall”.

Instead of a monetary goal, this project aims to strike down 1000 russian reconnaissance drones.

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.

I rarely share videos here, but it's Friday, so it's fine. Also, this video provides some food for thoughts.

This is a reaction video, if you wish, to an interview with Pieter Levels on the Lex Fridman podcast. I don't link the whole podcast episode here, because it's long, and it's also linked to the video I'm sharing.

You can think whatever you want about Lex and his podcast specifically, but here is what's interesting about this particular quest: he's running several websites that allegedly bring him $3M a year, and all of these websites are hosted on a single DigitalOcean server that costs $400. All these websites are created with PHP and JQuery.

We need to address an elephant in the room here: he does use 3rd party vendors to do some heavy-lifting for his projects, but many "startups" that have much more complex technical stacks do that as well.

I'm not arguing that this is the way to go for everyone, but still an interesting thing to think about.

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.

​​Our friends from UA DevOps started a new fundraiser for Special Operations units.

You can donate to this Monobank Jar:

P.S. Also, here’s a picture of a drone you’ve helped to fund!

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!

A blog post from DHH on why don't more people use Linux.

Technically, the answer is quite simple for the general public: no one uses an OS for the sake of an OS itself. People use computers to run specific software to help them with their routines. OS is secondary.

However, he raises another question: if you're not a part of the "general public", what if you're a person who writes code that then (most likely) is run on Linux, shouldn't you know your tools better in this case?

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.

Pinterest explains how their engineers deal with web performance. It’s a three parter:

- Part I: about the team structure
- Part II: about systems and practices for performance degradation detection
- UPD: There is a Part III, actually. It's focused on proactive
measures to detect performance
degradations.
Thanks to an attentive subscriber who spotted it!

I found it particularly interesting, how they organize teams and share
responsibility for web performance. It would be very interesting to
hear, how did they get there: was it a top-down instruction or a natural
evolution. Maybe, that should have been the part III, but who knows.

P.S. Pinterest is the best social media out there!

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.
