Sito compromesso: i passi immediati per contenere il danno e ripristinarlo

Un articolo su DEV Community illustra come riconoscere un sito web hackerato, dai redirect verso siti sconosciuti agli avvisi di malware di Google. La prima raccomandazione è sostituire subito il sito con una pagina di manutenzione statica, per limitare infezioni dei visitatori e danni alla reputazione. Viene poi indicato di cambiare tutte le credenziali collegate al progetto, come hosting, database, CMS ed email, usando password lunghe e uniche. Il testo elenca anche le verifiche da fare per capire come è avvenuta l'intrusione, tra cui file PHP modificati di recente, utenti admin sconosciuti e cron job malevoli. Infine suggerisce di ripristinare un backup pulito, oppure di procedere con una pulizia manuale se il backup non è disponibile.

Why local RAG systems succeed or fail on chunking, retrieval, and index freshness

Self-hosted models such as Ollama, llama.cpp, and vLLM have made private inference affordable, but retrieval-augmented generation still breaks in familiar ways, including poor chunks, stale indexes, and citations to documents the model never used. The article argues that local RAG is mainly a product decision, since chunking, embedding choice, and refresh cadence determine whether users trust the system. It recommends structure-aware chunking, hybrid dense and keyword retrieval for identifiers and proper nouns, and freshness commitments backed by reindexing. It also advises requiring quoted supporting spans and rejecting answers drawn from empty retrieval sets. Local deployment is favored for privacy, predictable cost, and regulated environments, though some teams pair it with cloud models for demanding reasoning tasks.

Sloth Sort: local Gemma 3 tool automatically renames messy screenshots and downloads

Sloth Sort is an open-source tool that watches the Desktop and Downloads folders for files with generic names like screenshots and scans. When such a file appears, Gemma 3 running locally through Ollama identifies its contents and renames it with a date-first, descriptive name. Only throwaway names are changed, and every rename can be reversed from a review page on the local machine. The model runs entirely on the user's computer so sensitive screenshots never leave it, and it unloads after five idle minutes. The project was submitted to the Hacktoberfest Open-Source AI Challenge.

Asynchronous JavaScript: How Non-Blocking Operations Work

Some JavaScript tasks, such as fetching data from an API or waiting on a timer, take time to finish. Asynchronous JavaScript lets the language handle these tasks without halting other code from running. Synchronous code executes line by line in order, while asynchronous code can schedule work, like a setTimeout callback, to run later. The article's example shows a log statement printing before a delayed callback, illustrating this behavior. Common uses include fetching API data, loading products on shopping sites, sending login details, uploading files, and communicating with databases through a backend.

ShortSingh: Android app's model search now hides models your phone cannot run

Off Grid AI Mobile (OGAM) has added a filter to its Android model search so users avoid downloading AI models their phones cannot load. Results are filtered by the phone's RAM, showing only models that will load and marking those that only just fit as Tight. Each model appears once even when many uploads exist, and models needing a newer engine, speed-up helper files and image generators are left out of chat search. The changes arrived in versions 0.0.116 and 0.0.117, and search is free with no account required. Once downloaded, models run on the phone without an internet connection.

Arrange My Files AI Builds Reviewable Plans to Organize Documents Without Touching Originals

Arrange My Files AI is a tool that turns cluttered folders into organization plans users can review before anything is copied. Original files stay in place, and the included batch is copied into a new output session. Files with clear content go into category folders, while uncertain or unsupported files are placed unchanged in a Needs Review folder. The author tested the app with nine dummy files, where the engine renamed some files based on document titles while preserving descriptive names. The developer notes that the system performs quick, bounded analysis rather than full document understanding, so some files still require manual review.

Why AI debugging loops fail and how staged prompts can break them

Developers often find that repeatedly pasting errors into an AI model yields confident patches that shift the problem elsewhere, leaving code messier and the root cause unclear. The author argues the issue is that a single "fix this" request bundles reproduction, localization, cause analysis, and regression checking together, causing the model to skip ahead and guess. The proposed remedy is to ask for one stage at a time, starting with reproducing the bug from a clean state and listing missing environment details first. Subsequent stages cover halving the search space through targeted checks, explaining the root cause with a code comment, and identifying other code that relies on the same faulty assumption. The post also promotes PromptAlo, a Chrome extension for saving and reusing such prompts across ChatGPT, Claude, and Gemini.

LLC vs. Sole Proprietorship: Choosing a Structure for a Small US Freelance or Agency

A sole proprietorship is the default business status for anyone doing paid work under their own name, requiring no formation paperwork and offering no legal separation from the owner. An LLC is a separate legal entity formed with the state, which creates a line between personal assets and business liabilities, but it involves a one-time filing fee and often ongoing annual charges. Annual costs vary widely by state, from near zero in some places to a flat $800 per year minimum in California regardless of income. The article notes that an LLC does not shield against claims tied to a freelancer's own professional negligence, and that both structures generally carry self-employment tax obligations, which an S-corp election can change. Advice differs by situation: sole proprietorship suits early-stage or low-risk work, while an LLC may fit higher-liability work, consistent income, or clients who prefer contracting with an entity.

Managing Cognitive Load and Uncertainty in Engineering Problem Solving

A DEV Community article, the second in a series on the psychology of problem solving, examines how engineers can work through complex challenges. It argues that solving a problem depends not only on knowledge but on how much information a person can hold in working memory at once. The author suggests offloading information into external tools such as diagrams, logs, and structured tables to reduce mental strain. The piece also covers making decisions under uncertainty, adapting search strategies, and learning from feedback. Its stated aim is to encourage more deliberate management of the problem-solving process rather than rigid methodologies.

How Wikidata-based daily trivia generation hit labelling, timeout and data-quality problems

A team building daily trivia quizzes sourced every question from Wikidata facts so that answers could be checked and linked back to their source items. They found that many proper names exist only under a multilingual label, so queries filtering by English or French silently dropped items such as Juneau and several famous people. Heavy SPARQL queries also timed out, which they addressed by starting from Wikipedia-mapped item lists in batches and saving results incrementally. Other fixes covered handling multiple conflicting values per property, excluding misleading discoverer and music entries, and correcting outdated names and duplicate continent entries. The article, measured on 23 October 2026, also notes Wikimedia Commons thumbnail sizes that the service accepts.

How to Set Up FAQ Schema With JSON-LD So Google Can Show Rich Results

FAQ rich results can expand a search listing and may supply passages that AI Overviews quote. The core markup is a FAQPage containing Question entries, each with one acceptedAnswer, placed in the page's HTML. Implementations commonly fail due to small technical issues, such as Q&A content that exists only in the markup and not in the visible page. Guidance includes keeping questions genuine, answers short and self-contained, and validating pages with Google's Rich Results Test before monitoring the Enhancements report in Search Console. The author also notes that valid markup does not guarantee that Google will display the rich result.
