The document provides instructions for downloading and installing Oracle 10g Express Edition, including links to the download page and installation guides. It then outlines how to start up and log into the Oracle database, describes some basic SQL commands like DESCRIBE and HOST that can be used, and provides an example of creating a SQL batch file to automate running multiple SQL statements.

Etsy is using Solr and Lucene to serve queries at a rate of more than 8 billion per year (and growing). In this case study, we will describe how Etsy has integrated Solr/Lucene into our continuous deployment infrastructureallowing for Solr configuration, Java-based indexers, and query parsing logic to go from passing tests to production code in minutes
Redis is a rock-solid platform for a
variety of real-world use cases, in particular as a poor man’s message queue. At Apple Maps, we built a service to show live
I/O from thousands of concurrent SSH sessions in real-time using Redis, Lua scripts, node.js and HTML5 Server-Sent Events.
Although our architecture isn’t ideal, and we would do things differently today, our system has performed very well in the
real-world over the past couple of years. In particular, after some initial failures, it has scaled very well as usage has grown
much faster than we had ever anticipated. I’ll talk about the initial design, implementation, and the evolution of specific
features to address real-world memory usage and performance challenges

Imagine for a while that Rails wouldn't exist. How would we write a MVC app from scratch?
Rack provides a minimal interface for developing web applications in Ruby. In fact it's the solid foundation of all major Ruby powered web frameworks.
During this talk we will dive deep into Rack. We will see the smallest possible Rack Application and learn how it works, by studying Rack internals. We will grow the Application step by step till we implement it in simple MVC style.
Presentation with a brief history of C, C++ and their ancestors along with an introduction to latest version C++11 and futures such as C++17. The presentation covers applications that use C++, C++11 compilers such as LLVM/Clang, some of the new language features in C++11 and C++17 and examples of modern idioms such as the new form compressions, initializer lists, lambdas, compile time type identification, improved memory management and improved standard library (threads, math, random, chrono, etc).

NYC* 2013 - "Advanced Data Processing: Beyond Queries and Slices"DataStax Academy
The ColumnFamily data model and wide-row support provides the ability to store and access data efficiently in a de-normalized state. Recent enhancements for CQL's spare tables and built-in indexing provide the capability to store data in a manner similar to that of relational databases. For many use cases hybrid approaches are needed, because complete de-normalization is appropriate for some access patterns whereas more structured data is appropriate for others. At times a single logical event becomes multiple insertions across multiple column families. Likewise a user request might require a several reads across different column families. This talk describes some of these scenarios and demonstrates how advanced operations such multiple step procedures, filtering, intersection, and paging can be implemented client side or server side with the help of the IntraVert plugin.
A lot has changed since I gave one of these talks and man, has it been good. 2.0 brought us a lot of new CQL features and now with 2.1 we get even more! Let me show you some real life data models and those new features taking developer productivity to an all new high. User Defined Types, New Counters, Paging, Static Columns. Exciting new ways of making your app truly killer!

3. Start and Login to Oracle 10g Exp
• To start:Oracle PopUp menu
– Start database: wait for the services to complete:
• The OracleXETNSListener service was started successfully.
• The OracleServiceXE service is starting..............................
• The OracleServiceXE service was started successfully.
– Go to database home page
• Login
• Accounts
– System administrator
– User
• Logout
– Stop database
5. Run SQL Command Line
SQL*Plus
• First start Oracle
• Then choose Run SQL Command Line
from Oracle menu
• At the prompt:
– Connect accoutName
6. Commands at Oracle SQL>
• To list all commands:
– SQL>help index
• To list all tables:
– Select * from Cat;
• To display a table structure:
– Describe tableName
• To run a DOS command from Oracle:
– Host DOSCommand
– Example: Host dir
7. Creating SQL Command Batch File
• Creating a batch file with .sql extension
– At SQL>Edit filename
• Ex: SQL>edit c:batch1.sql
• Use START command to execute the
batch file.
– SQL>START c:batch1.sql
• See the batch file contents at SQL>
– SQL>host type c:batch1.sql
8. Batch File Example
Drop table hotel;
Create table hotel (hotelno char(3), hotelname varchar(20),city varchar(20));
Insert into hotel values('h1', 'Grosvenor','CHICAGO');
Insert into hotel values('h2', 'Westin','SAN FRANCISCO')
Insert into hotel values('h3', 'Hilton','London');
