How to Handle API Rate Limits When Building Crypto Trading Bots

·1 views

Crypto trading bot developers frequently run into API rate limits imposed by platforms like Binance, CoinGecko, and CryptoCompare, each with different thresholds and rules. A common cause of hitting these limits is polling endpoints too frequently and failing to cache responses that change slowly. Developers are advised to implement aggressive caching with appropriate time-to-live values, use exponential backoff when a 429 error is returned, and monitor rate-limit headers to track remaining request quotas. Building fallback logic across multiple data sources is also recommended, since no single API guarantees full uptime. Following these practices helps bots stay within limits while maintaining reliable access to market data.

How to Build a Production-Grade Apache Reverse Proxy with Load Balancing and Failover

Apache is widely used as a TLS-terminating reverse proxy in front of backend servers like Node.js, Gunicorn, or Tomcat, but basic ProxyPass configurations often cause 502 errors and crashes under real traffic load. A critical security requirement is setting ProxyRequests Off to prevent Apache from acting as an open relay that attackers can exploit for DDoS or spam. Connection pooling through proxy directives helps Apache recycle TCP connections during traffic spikes, avoiding backend connection exhaustion. Administrators must also distinguish between the Timeout directive, which governs client-to-Apache communication, and ProxyTimeout, which controls how long Apache waits for a backend response. Finally, headers such as X-Forwarded-Proto and ProxyPreserveHost must be configured so backend applications correctly identify the original client IP and protocol, ensuring proper rate limiting and routing.

How ChatGPT, Perplexity, and Google AI Overviews select sources to cite

AI answer engines like ChatGPT, Perplexity, and Google AI Overviews use retrieval-augmented generation pipelines that pull candidate pages, rerank them, and cite only a small fraction in the final response. An AirOps analysis of roughly 15,000 prompts found ChatGPT cites just 15 percent of retrieved pages, meaning most content is evaluated and silently discarded. ChatGPT relies heavily on Bing's index, with one study finding over 87 percent of its citations matching Bing's top organic results for the same query. Perplexity uses hybrid keyword and vector retrieval combined with multi-stage reranking that weighs freshness, domain authority, and topical fit, favouring pages on established trusted domains. Google AI Overviews differ by citing specific extractable passages rather than whole pages, with roughly 96 percent of cited sources carrying strong expertise, authoritativeness, and trustworthiness signals.

How a Static Open Source Website Evolved into a Live Intelligence Platform

The team behind WebiU 2.0 set out to redesign a static website for an open source organization, only to discover the real challenge was a data management problem, not a frontend one. As repositories multiplied and contributor activity changed daily, manually keeping the site up to date became unscalable. The developers shifted their approach by treating GitHub as a live data source rather than a static reference, enabling dynamic collection of repository metadata, contributor stats, and project health indicators. This architectural rethink transformed the platform from a simple informational site into a system capable of reflecting real-time open source activity. The experience highlights how growing open source organizations eventually outgrow static web infrastructure and require purpose-built data pipelines to stay accurate.
