For much of its existence, JavaScript has been slow. No one complained until developers created complex web applications with thousands of lines of JavaScript code. Although newer JavaScript engines have improved the situation, there’s still a lot to understand about what makes JavaScript slow and what you can do to speed up your code.Read less
This document provides an overview and agenda for an AWS webinar on AWS Glue. It introduces AWS Glue as a fully managed and serverless ETL service that can manage metadata for various data sources. The webinar will cover the background of AWS Glue, its key features including being serverless and enabling secure development in notebooks, use cases, pricing, and a conclusion. It also provides detail
The document provides tips and explanations for various MongoDB commands and operations including explain, hint, setProfilingLevel, currentOp, and mongostat. It discusses using indexes to optimize queries, setting profiling levels to log slow queries, using currentOp to view currently running operations, and using mongostat to view MongoDB server statistics.
This document contains links to MongoDB documentation pages about sharding, databases, collections, inserting, querying, updating, indexing, replication, and backups. It includes a link to a slideshare presentation on MongoDB sharding and links to pages explaining replica set internals and operations.Read less

The document discusses using OpenStreetMap (OSM) to map areas in response to natural disasters. It provides examples of how OSM was used after the 2010 Haiti earthquake and 2011 Japan earthquake and tsunami. It outlines how OSM data is collected through tools like GPS, aerial imagery, and local knowledge. The document promotes contributing to OSM to build free maps that can help relief efforts and
FellowBuddy.com is an innovative platform that brings students together to share notes, exam papers, study guides, project reports and presentation for upcoming exams. We connect Students who have an understanding of course material with Students who need help.

WebSockets allow for bidirectional communication between a client and server over a single TCP connection. They improve on older "Comet" techniques which used polling and long-polling to simulate real-time updates. With WebSockets, the client can open a WebSocket connection to the server which sends messages at any time without needing an explicit request. This enables real-time applications with
Keep hearing about Plack and PSGI, and not really sure what they're for, and why they're popular? Maybe you're using Plack at work, and you're still copying-and-pasting `builder` lines in to your code without really knowing what's going on? What's the relationship between Plack, PSGI, and CGI? Plack from first principles works up from how CGI works, the evolution that PSGI represents, and how Plac
