Loading a Petabyte into PostgreSQL Before New Year — and What Happened Next
It all started as a joke by the office coffee machine. While everyone else was busy tuning hardware and squeezing out extra TPS, one team asked a simple question: why not just shove a petabyte of data into PostgreSQL and see how it holds up?
It was December 10th, New Year was less than a month away, and that itch that all engineers know? It hit hard. What began as a joke quickly turned into a real, non-trivial experiment, complete with a minefield of gotchas. Here's the story of what happened next: https://u.habr.com/HROPl

Find and Remove Invisible Characters from AI Text
AI-generated text isn't as clean as it looks. Copying from ChatGPT, Claude, or Gemini can introduce hidden Unicode characters — digital watermarks that break code and formatting, causing headaches for writers and developers.
A free extension, “Invisible AI Chart Detector” for Chrome and VS Code, solves this. It finds and removes these invisible characters with a single click and normalizes "fancy" typography to standard ASCII, ensuring your text is clean and predictable.

Postgres Pro TDE — security and performance
Not all Transparent Data Encryption (TDE) for PostgreSQL is the same. A new article reviews TDE implementations from Percona, Cybertec/EDB, and Pangolin/Fujitsu, analyzing the trade-offs between performance, reliability, and flexibility.
The text details how Postgres Pro Enterprise implements key rotation without rewriting entire tables — a significant advantage for security and performance. It also covers why AES-GCM was the clear choice for the encryption algorithm.

Why LLMs Drift into Convincing Nonsense (And a Practical Solution)
Ever get an answer from an LLM that’s elegant, logical, and completely wrong? The model isn't "understanding" your complex idea; it's guiding you toward a solution that's computationally cheap for it.
This is an emergent consequence of probabilistic optimization, where the AI funnels users down predefined "corridors" to a simple, template-based answer. It's a system where mathematical efficiency serves commercial objectives. The article explores why this happens and offers a way to combat it.

Autism spectrum disorders and a career in IT: personal experience
"I'm stunned by the illogicality of others, and they are stunned by the fact that I'm a robot"
In a new article, an author shares their personal experience of navigating the world and an IT career with an autism spectrum disorder. For a long time, they felt like an alien, unable to understand the seemingly irrational actions of others while being seen as strange themselves. This is a personal story about the journey from feeling like a "withdrawn, gloomy dude" to understanding a unique perspective.

AI Slop Coding: The Rise of Ridiculously Long Attack Chains
Threat intelligence research has uncovered a series of unusual, targeted attacks using GitHub repositories to store both malicious files and victim data.
The campaigns, active since at least September 2024, don't rely on complex malware. Instead, they use ridiculously long chains of very simple scripts that appear to be heavily AI-generated.
This approach combines the strategic thinking of an APT-style attack with the low-effort execution of a "script kiddie," creating a bizarre but effective new threat.
Let's dive into the anatomy of these campaigns and see how AI enables this new breed of attack.

Beyond ora2pg: A Better Way to Migrate from Oracle to Postgres
Migrating schemas and data from Oracle DB to Postgres Pro Enterprise is a notoriously rocky road, full of countless pitfalls for administrators and developers.
Interestingly, Postgres Pro Enterprise includes extended features specifically designed to mimic Oracle's mechanisms and smooth out this very process.
However, the widely-used open-source utility ora2pg doesn't support them. This gap led to the creation of ora2pgpro, a tool built to leverage these unique features for a more seamless transition.
Let's explore the specific migration challenges and see what makes this new tool a better fit for the task.
