How to Build a Free Inventory Alert System in Google Sheets Using Apps Script

·1 views

A tutorial published on DEV Community outlines how to build a real-time inventory dashboard inside Google Sheets without paid software. The guide centers on automating reorder point calculations using the formula: average daily sales multiplied by supplier lead time, plus safety stock. A key distinction the tutorial emphasizes is tracking available stock — units on hand minus those already allocated to open orders — rather than raw on-hand figures, which is a common cause of overselling. Three Google Apps Script functions handle status classification, stock availability, and reorder point computation, with a single batch read-write approach to keep refresh times fast across large product catalogs. A scheduled daily trigger runs an email alert function that notifies purchasing teams whenever any SKU crosses into a low-stock or out-of-stock status.

Nine Free LLM API Providers That Require No Credit Card in 2026

A developer guide published on DEV Community outlines nine LLM API providers — including Google Gemini, Groq, Cerebras, and OpenRouter — that offer free usage tiers without requiring credit card registration. The guide is aimed at developers seeking to reduce API costs or experiment with multiple models during prototyping. A key recommendation is to manage multiple providers as a pool and implement automatic fallback routing, using tools like LiteLLM, to maintain availability when rate limits are hit. Developers are also warned that output format inconsistencies between models can break conversation context in multi-turn AI agents. The guide cautions that free-tier services often permit user data to be used for model training, making them unsuitable for handling sensitive or confidential information.

25 Years of Online Gaming: How Multiplayer Games Evolved Behind the Scenes

Online gaming has undergone a dramatic technical evolution over the past 25 years, shifting from clunky page-reload web games like NeoQuest to seamless real-time multiplayer experiences. Early browser-based games relied on remote servers to process every player action and reload entire web pages each time, making gameplay slow but reliably saved. The rise of Adobe Flash moved game logic onto players' own devices, dramatically speeding up gameplay but opening the door to score manipulation by hackers, which triggered an ongoing battle between cheaters and developers. Modern games address this by running core logic on central servers using client-server or peer-to-peer architectures, though unstable connections can still cause glitches like teleporting characters or phantom hits. Today's apps also integrate UI components, native programming languages, and hardware APIs to coordinate millions of players across devices in near real time.

A Simple Reading Trick That Makes Python Comprehensions Easy to Understand

Python list comprehensions often confuse beginners not because they are inherently complex, but because they are typically read in the wrong order. A developer guide on DEV Community explains that comprehensions should be read starting with the 'for' clause, then the 'if' filter, and finally the leading expression. This approach applies to list, dictionary, and set comprehensions, as well as nested comprehensions involving multiple loops. The guide also highlights generator expressions as a memory-efficient alternative, noting they store only the generation logic rather than all computed values at once. Practical code examples throughout the article demonstrate how this reading method simplifies comprehension of even multi-level nested structures.
