The document compares and contrasts iPhone and Android platforms. It discusses their different programming languages, development environments, user interface architectures, strengths and weaknesses. Key topics include Objective-C vs Java, Xcode vs Eclipse, iOS view controllers vs Android activities/fragments, and each platform's native capabilities and limitations. The document provides an overview of building apps for iPhone and Android.
This document summarizes Mosa Siru's engineering work at DeNA and Gunosy. It describes Gunosy's RSS/Atom feed crawler system which includes components like a job queue, fetcher, parser, updater, content generator, and indexer. It also discusses technologies used like Python, Celery, MySQL, S3, Elasticsearch. The system is designed to efficiently parse, store, generate content and index feeds at scale.
This document summarizes a microservices meetup hosted by @mosa_siru. Key points include:
1. @mosa_siru is an engineer at DeNA and CTO of Gunosy.
2. The meetup covered Gunosy's architecture with over 45 GitHub repositories, 30 stacks, 10 Go APIs, and 10 Python batch processes using AWS services like Kinesis, Lambda, SQS and API Gateway.
3. Challenges discussed were managing 30 microservices, ensuring API latency below 50ms across availability zones, and handling 10 requests per second with nginx load balancing across 20 servers.
