Wikipedia: Tuned Predictions on Big Data
This project was completed by Scott Dobbins and Rachel Kogan, who enrolled in the NYC Data Science Academy's 12-Week Data Science Bootcamp. Learn more about the program: http://nycdatascience.com/data-science-bootcamp/
Given that both Wikipedia and comments sections of most websites are freely open to anyone to edit at any time, how has Wikipedia managed to remain such a useful resource while most comments sections are ridden with vandalism, ads, and other counterproductive user behavior?
We believe the answer is two-fold: 1) Wikipedia has an army of bots that quickly identify and revert vandalism so that the worst edits are usually never seen by people and the site generally maintains itself in a well-kempt state, and 2) Wikipedia has a strong community of administrators and other contributors who routinely clean the site’s flagged contents.
Vandalism is relatively easy to flag, though a few clever edits manage to stay on the site for a long time. What about site content problems that are more subjective, like bias? Wikipedia users do routinely manually flag pages with point-of-view (POV) issues, though with millions of pages and no machine-based approaches, the site can only manage to confidently maintain neutrality on the more well-trafficked pages.
Here we propose a solution to solve some of the more intractable content issues for Wikipedia and other sites using Natural Language Processing (NLP) and machine learning approaches. The sheer quantity of data managed by Wikipedia and similar sites requires distributed computing approaches, so we show here how Apache Spark can upgrade common algorithms to run on massive data sets.
Webinar: What's New in Pipeline Pilot 8.5 Collection Update 1?
The document discusses new features in Pipeline Pilot 8.5 Collection Update 1. It introduces protocol comparison capabilities, updates to the documents and text collection including new visualization and search components. The Accelrys Query Service allows unified searching across data sources. Imaging components now include curvature analysis and color deconvolution. The NGS collection includes performance updates and new viewers. Additional resources and services are available to assist with the upgrade.
Www Search Engine But Not In Perl
The document summarizes the goals, architecture, and implementation of building a scalable distributed web search engine. It discusses:
1) The goals of building an engine capable of indexing over 1 billion web pages using principles from Google and other major search engines.
2) The architecture includes crawling websites to collect data, indexing text into numeric representations, merging indexes, and searching by keyword.
3) The implementation uses Microsoft .NET and C# on Linux via Mono, with over 90,000 lines of code written from scratch with few dependencies.

This document summarizes the key points from a lecture on public health research methods. It discusses recommendations for organizing data analysis workflows, including using annotated text files for code, GitHub for version control and collaboration, and having others replicate analyses using different software. It also covers citation management options, ethics review boards, and some Berkeley-specific resources. The overall lecture provided an overview of best practices for conducting and documenting public health research.
HDF Kita Lab: JupyterLab + HDF Service
The HDF Group is providing a hosted JupyterLab environment called HDF Kita Lab that provides access to HDF data stored on AWS S3 via the HDF Kita Server. HDF Kita Lab extends JupyterLab with features like auto-configuring the Kita Server and HDF branding. It runs on a Kubernetes cluster in AWS that can scale to handle different numbers of users. Each user gets computing resources and access to HDF data on S3 for analyzing via commonly used Python packages. The data on S3 provides unlimited storage and sharing capabilities between users.
Workflow Engines + Luigi
Vladislav Supalov introduces data pipeline architecture and workflow engines like Luigi. He discusses how custom scripts are problematic for maintaining data pipelines and recommends using workflow engines instead. Luigi is presented as a Python-based workflow engine that was created at Spotify to manage thousands of daily Hadoop jobs. It provides features like parameterization, email alerts, dependency resolution, and task scheduling through a central scheduler. Luigi aims to minimize boilerplate code and make pipelines testable, versioning-friendly, and collaborative.

This document describes a U-SQL case study using Azure Data Lake to analyze web analytics data from Cegid websites. It involves developing three U-SQL scripts: 1) to extract and convert JSON log files to TSV format, extracting and pivoting custom dimensions, 2) to aggregate events into sessions, and 3) to further aggregate sessions into visitors. The case study demonstrates how U-SQL allows SQL-like querying and manipulation of large datasets with integrated C# code for custom logic, and discusses best practices for optimizing U-SQL scripts.
Streaming Distributed Data Processing with Silk #deim2014
Silk is a framework for building and running complex workflows of distributed data processing. It allows describing dataflows in Scala in a type safe and concise syntax. Silk translates Scala programs into logical plans and schedules the distributed execution through various "weavers" like an in-memory weaver or Hadoop weaver. It performs static and run-time optimizations of dataflows and supports features like fault tolerance, resource monitoring, and UNIX command integration. The goal of Silk is to enable distributed data analysis for all data scientists through an object-oriented programming model.

Lean startup machine
The document summarizes the results of three rounds of testing a potential startup idea using the Lean Startup methodology at the Lean Startup Machine conference in Boston. In Round 1, the team hypothesized a website to connect a teen named Julie with scientists, but testing found teens were not focused on career planning. Round 2 focused on parents helping kids' science interests, but the idea of science packages was unclear. Round 3 simplified the idea to educational adventure trips led by scientists, which generated interest and signups. The document reflects on lessons learned about pivoting customer segments and solutions based on testing.
Firewalls-Intro
Firewalls are systems designed to control network access by enforcing an access control policy. They work by examining packets and filtering them based on rules like IP addresses, protocols, and ports. There are different types of firewalls including packet filtering, proxy, and application layer firewalls. While firewalls help protect networks from unauthorized access and provide logging, they have limitations as they only control connectivity and not other aspects of security like encryption. It is important to take additional precautions like using strong passwords, keeping software updated, and practicing safe online habits.
Tecnologia de la construccion y la arquitectura
This document discusses construction technology and structural systems and their relationship to architecture. It introduces the topics and provides examples, including discussing Sky City, a proposed mega-tall building project in China. Several sections cover introductions, technologies, structures, relationships to architecture, and an example project with a provided link for more details.
Green it initiatives
This document discusses how information technology applications can help abate climate change. It focuses on data centers and how their energy usage and emissions can be reduced through virtualization and cloud computing. Virtualization allows multiple virtual servers to run on a single physical server, improving hardware utilization and reducing energy costs. Cloud computing provides on-demand access to shared computing resources over the internet on a pay-per-use basis, improving scalability and efficiency while reducing hardware needs. Both approaches can significantly lower the energy consumption and carbon footprint of data centers.
SANITATION AND SAFETY IN FOOD & BEVERAGE OPERATION
Sanitation and safety in food service operations are important to prevent food poisoning outbreaks, injuries, lawsuits, and loss of business. Managers are responsible for ensuring food is properly stored, prepared, and served under sanitary conditions to avoid chemical or bacterial contamination. They must also address safety concerns and implement training and inspection programs. When designing or remodeling a kitchen, factors like employee safety, noise, lighting, and government codes should be considered. Providing consistent, high-quality service is key to satisfying guests.
Experimente altfel
The document discusses an experiment conducted at the "Closca" school in Carpinis, Alba county. It encourages trying new approaches or experimenting differently. No other details are provided about the specific experiment, approaches, or outcomes in the very brief single sentence document.
FOOD & BEVERAGE MANAGEMENT
1. Food and beverage service involves providing an enjoyable experience for guests through standardized activities and procedures.
2. There are various types of service including American, English, French, buffet, cafeteria, and others depending on the operation.
3. Table service brings food to seated guests while buffet and cafeteria service allow guests to serve themselves from displayed items. The style used depends on the operation and satisfying guest needs.
