How to Build a Private Docker Registry Using Zot and Backblaze B2

·1 views

A developer has published a practical guide detailing how to self-host a private Docker registry using Zot, an open-source OCI registry from the Linux Foundation ecosystem. The setup uses Backblaze B2's S3-compatible storage for image data and Docker Compose to manage the full stack on a Linux server. Zot was chosen over alternatives like Harbor and the official CNCF Distribution registry for its balance of features, including a built-in web interface, repository-level access control, retention rules, and audit logging. The configuration includes separate accounts for GitHub Actions and production servers, with an admin account overseeing all repositories. The guide covers HTTPS setup, role-based access control, automatic tag cleanup, and GitHub Actions integration.

Study Quantifies How Much Information Each LLM Parameter Can Store

A joint paper by Meta, DeepMind, Cornell University, and NVIDIA, accepted at ICML 2026, investigates the information storage capacity of large language model parameters. Researchers found that GPT-style Transformer models store approximately 3.6 bits of information per parameter in BF16 format, rising to 3.83 bits under FP32 precision. To isolate rote memorization from generalization, the team trained models ranging from 500,000 to 1.5 billion parameters on random, patternless bit strings. The study identifies a critical phase transition point where training data volume matches model capacity, at which memorization declines and generalization ability rises sharply — coinciding with the well-known double-descent phenomenon. The findings also highlight that while average training samples are unlikely to be leaked from large models, rare or sensitive content such as proprietary code or non-English text remains at high risk of memorization and exposure.

Lab Guide Shows How Browser Agents Fall for Hidden Prompt Injection Attacks

A technical lab exercise published on DEV Community demonstrates how browser-based AI agents can be manipulated through indirect prompt injection, where hostile instructions are embedded in web page content. The attack exploits a confused-deputy pattern, causing the agent to execute unintended actions — such as sending a POST request — simply by reading a page the user asked it to summarize. The lab walks participants through building a local attacking page, an action-recording sink, and an audit log to capture agent behavior under both vulnerable and hardened configurations. Researchers can then compare outcomes between a permissive policy profile and a hardened one that treats page content as untrusted, restricts destinations, and requires user approval for consequential actions. The exercise is model-agnostic, runs entirely on local services using dummy data, and is designed to highlight the critical trust boundary between web content and an agent's operational authority.

AI Hiring in India Rises 16% as Overall IT Recruitment Falls 3%

India's AI-related hiring in the IT sector grew 16% year-on-year in June 2026, even as overall IT job listings declined by 3% in the same period, according to Naukri's monthly JobSpeak report tracking over 150,000 firms. Across 14 major sectors, roles focused on AI and machine learning rose by 25%, with industries like insurance and consumer goods leading adoption beyond traditional tech companies. Experts including Info Edge CEO Hitesh Oberoi attribute this divergence to companies deliberately directing capital toward specialized AI talent rather than general IT recruitment. The shift reflects broader pressure on India's $315 billion IT industry, which faces reduced global client spending and disruption from generative AI threatening high-volume, low-margin service models. Major firms like TCS are responding by restructuring toward leaner workforces where AI handles routine tasks and human employees focus on high-level architecture and AI oversight.

Java Inheritance Explained With a Real E-Commerce Example

Inheritance in Java allows a child class to extend a parent class, reusing shared fields and methods while adding its own unique attributes. A practical example uses an e-commerce platform selling electronics, clothing, and groceries, where all products share a name, price, and seller, but differ in details like warranty period or expiry date. A base Product class holds the common fields, while subclasses like Electronics extend it using the extends keyword and initialize inherited fields via the super() constructor call. Child classes can also override parent methods to display category-specific information instead of the generic output. This approach eliminates code repetition and makes future updates, such as adding a discount field, easier to manage across all product types.
