Rails made Web application development substantially more enjoyable. Surprisingly, even in Rails 2.3, there are some areas that still suck: Erb-Templates are the typical HTML/XML tag soup mess, CSS-Files are, well, CSS files. HAML and SASS are two technologies to fix this: HAML templates are concise and powerful, SASS makes writing CSS almost a fun experience. Be there or be width:20px height:20px.
Beth Transue, a librarian, provides tips for searching for genetics information, including defining concepts, using keywords and subject terms, selecting appropriate databases, and using Boolean operators like AND and OR. The document recommends PubMed as a genetics database created by the National Library of Medicine that contains medical articles and is free to access. It also recommends OMIM, a catalog of human genes and genetic disorders linked to PubMed. When evaluating resources, the document advises considering the publisher, author, purpose, date, and personal knowledge, especially for internet/web resources.
The document summarizes Crosby Middle School's technology readiness according to the Texas Campus STaR Chart for the 2007-2008 school year. It shows ratings for four key areas: I) Teaching and Learning, II) Educator Preparation and Development, III) Leadership, Administration and Instructional Support, and IV) Infrastructure for Technology. Crosby received ratings of Developing Tech in areas I and II, Advanced Tech in area III, and Advanced Tech in area IV. A chart compares these results to ratings from 2005-2006 and 2006-2007. Instructions are provided on how to access Crosby's full STaR Chart online.
- The document summarizes data from the Sunrise balloon-borne solar observatory, which achieved high-resolution spectro-polarimetric observations of the solar atmosphere using instruments like IMaX and SUFI.
- Preliminary data shown includes a map of the magnetic field vector and white-light images of the solar surface at resolutions as fine as 0.05 arcseconds (350 km).
- The science goals are to study magnetoconvection at small scales, observe the formation of magnetic elements, and investigate phenomena in solar active regions like penumbral filaments.
The document summarizes updates and initiatives from the biology library at a university. It discusses withdrawing print journals in favor of electronic access, creating departmental library webpages, and conducting an analysis of assignment types and use of library resources in biology courses. The goal is to better understand course needs, students' research skills, and how to enhance the library's support for the biology department.

The document discusses MongoDB, a document database that uses JSON-like documents with dynamic schemas, instead of the traditional table-based relational database structure. It provides an overview of MongoDB's features like document storage, querying, indexing, replication and scaling capabilities. It also discusses how to interact with MongoDB using the mongo shell and drivers in various programming languages like Ruby.
This document provides a summary of basic MongoDB operations using the Ruby driver. It discusses how to connect to MongoDB, select and work with databases and collections, perform CRUD operations like insert, update, remove, and find documents. It also covers more advanced queries with operators, sorting, pagination, and aggregation functions like count, distinct, and group.
The document discusses MongoDB, a document database that uses BSON (Binary JSON) as its data storage format. MongoDB does not enforce a schema and allows embedding rich data structures. It supports querying, indexing, replication, and scaling capabilities. The document also provides examples of using MongoDB from Ruby, including basic CRUD operations and queries.
10 fun projects to improve your coding skillsjan_mindmatters
The document outlines 10 fun projects to improve hacking skills, presented at Railswaycon 2010 in Berlin. The projects cover a range of technical skills like NoSQL databases, Twitter API, HTML5 canvas, JavaScript, websockets, sound processing, desktop applications, electronics, and multi-touch interfaces. Completing the projects would result in earning digital badges. More details on the projects and suggested technologies are provided on the speaker's website.
The document discusses MongoDB, a document database with a flexible schema. Some key points:
- MongoDB uses BSON as a binary serialization format for data storage and transmission.
- It supports rich queries on data using query documents and operators like $lt, $gte, $in, etc.
- Data can be easily scaled using replication and sharding.
- The document provides examples of basic usage like inserting, querying, and indexing data in MongoDB.
