In a world where data volume grows faster than GPU prices, the question “Where to store files?” becomes critical. Google Drive and iCloud are convenient but expensive and not unlimited. External hard drives are unreliable. Ready-made solutions from Synology or QNAP are good, but hit the wallet.
Enter TrueNAS. It’s an operating system that turns a regular computer into a powerful enterprise-grade network-attached storage (NAS).
Let’s figure out why TrueNAS is so popular, what challenges you’ll face, and whether this system is right for you.

If your business works with users from Russia, the question of where personal data is stored concerns you directly. Phones, names, email addresses, form submissions, employee data — all of this falls under strict localization requirements.
Many companies have lived for years in a “gray area”: data seemed to be stored both in Russia and abroad, and responsibility was blurred. But as of July 1, 2025 the rules changed so much that many common technical schemes are now considered a direct violation of the law.

Moving to the cloud or changing providers is always open-heart surgery. An engineer has to solve a lot of issues: how to move terabytes of data with minimal downtime? How to convert the schema? How to set up CDC (Change Data Capture) so as not to lose a single transaction during the switch?
Each major cloud provider has its own answer. Approaches are radically different: some provide just a “pipe” for data, some — a full ETL combine, some make migration serverless and as trouble-free as possible.

You deployed a new feature. Everything works perfectly on your local machine, and you’re happy with the result.
Then a message appears: “Nothing works for me.” You open the server logs — they’re empty. It turns out the error happened on the client side, from a user with an old browser version or unusual settings. And you might never have known about it.
This happens to almost everyone who deploys projects to production. It happened to me too, until I set up a tool that lets me see errors almost instantly — even if it’s the middle of the night and the problem occurred for a single user on the other side of the world.

Introduction: why “lab” metrics aren’t everything
“Lighthouse shows 100/100, but users complain about lag” — a familiar pain?
Synthetic tests (Lighthouse, WebPageTest) are great for development.
But the real user is sitting:
- on 3G in the subway,
- with 27 tabs open,
- on an old Android with 2 GB RAM.
These are exactly the scenarios captured by CrUX — the Chrome User Experience Report.
And CrUX Vis is a convenient and free visualizer of that data, launched in 2024.

If you use n8n for automations involving large language models (LLM), you probably know not only about their huge capabilities but also about the risks. LLMs remain a “black box”: they can accidentally disclose personal data, generate toxic content, or fall victim to prompt injection.
Until recently, you had to “wrap” an AI workflow with many IF nodes and complex Regex checks. It was cumbersome and unreliable.
Since version 1.119.0 n8n includes the Guardrails node — and it’s truly a game-changer. It’s your personal security layer that you can place at the input and output of any AI process.

A Simple Guide for Beginners: Jenkins → GitLab → GitHub → GitOps
Hello!
Are you just starting your DevOps journey or tired of hearing “and we use CI/CD” in interviews? Want to finally understand why code that works on your laptop fails on the server?
This article is your first step toward automation. And it will really be easy.
We’ll break everything down, without overloaded terms and with examples.
What is CI/CD (very simple)
CI/CD is when you press git push and everything else happens automatically.

How to take back control of your photos without sacrificing convenience
Hi everyone! Today I want to talk about something that’s been bothering me. Remember when Google Photos was completely free and unlimited? Those days are gone. Now we either pay a monthly subscription, juggle multiple accounts, or watch with anxiety as free iCloud space runs out.
We entrust the most valuable moments of our lives — our memories in the form of photos and videos — to corporations. They, in turn, can change the terms, raise prices, or, worse, lock your account and you lose everything.

In today’s world of AI models it’s easy to get lost. You have ChatGPT for some tasks, Claude for others, you want to experiment locally with Llama 3, and for coding — use a specialized model. The result is a desktop turned into chaos of browser tabs and applications.
What if there were a single unified interface that could connect to all those models? A place where you can easily switch between GPT-4o, a local Llama 3 and dozens of other models?

Yocto — this is not a distribution.
It’s a tool from which you build your Linux.
Like Lego, only for engineers.
🔧 Who needs Yocto
- Developing medical or industrial devices
- Require a 10-year support lifecycle
- Want a minimal image (15 MB)
- Working at Siemens, Bosch, or Toradex
🛠 How to build your Linux
# 1. Клонируем репозиторий
git clone git://git.yoctoproject.org/poky
cd poky
source oe-init-build-env
# 2. Настраиваем
echo 'MACHINE = "raspberrypi5"' >> conf/local.conf
# 3. Собираем
bitbake core-image-minimal
The resulting image will appear in tmp/deploy/images/.
