Regular Expressions Reference - Basic Syntax The regular expressions reference on this website functions both as a reference to all available regex syntax and as a comparison of the features supported by the regular expression flavors discussed in the tutorial. The reference tables pack an incredible amount of information. To get the most out of them, follow this legend to learn how to read them. The tables have six columns for each regular expression feature. The final two columns indicate whether your two chosen regular expression flavors support this particular feature. When this legend says "all versions" or "no version", that means all or none of the versions of each flavor that are covered by the reference tables: For the .NET flavor, some features are indicated with "ECMA" or "non-ECMA". For the std::regex and boost::regex flavor there are additional indicators ECMA, basic, extended, grep, egrep, and awk. For the PCRE2 flavor, some replacement string features are indicated with "extended".
Preface - - The Neo4j Manual v2.1.8 This is the reference manual for Neo4j version 2.1.8, authored by the Neo4j Team. The main parts of the manual are: The material is practical, technical, and focused on answering specific questions. It addresses how things work, what to do and what to avoid to successfully run Neo4j in a production environment. The goal is to be thumb-through and rule-of-thumb friendly. Each section should stand on its own, so you can hop right to whatever interests you. The included code examples are executed when Neo4j is built and tested. There’s other documentation resources besides the manual as well: Neo4j Cypher Refcard, see Cypher Refcard. Who should read this? The topics should be relevant to architects, administrators, developers and operations personnel.
Epoch Converter - Unix Timestamp Converter Supported SQL Syntax and Functions Supported SQL Statements With a few exceptions, the gateway provides full support for Oracle DELETE, INSERT, SELECT, and UPDATE statements. The gateway does not support Oracle data definition language (DDL) statements. No form of the Oracle ALTER, CREATE, DROP, GRANT, or TRUNCATE statements can be used.

The SELECT statement is fully supported, with these exceptions: CONNECT BY conditionNOWAITSTART WITH conditionWHERE CURRENT OF The UPDATE statement is fully supported. Oracle Functions All functions are evaluated by the SQL Server database after the gateway has converted them to SQL Server SQL equivalents. Functions Not Supported by SQL Server Oracle SQL functions with no equivalent function in SQL Server are not supported in DELETE, INSERT, or UPDATE statements, but are evaluated by the Oracle database if the statement is a SELECT statement.

Fun with Music, Neo4j and Talend By Neo4j Staff | July 13, 2013 Many of you know that I am a big fan of Belgian beers. But of course I have a number of other hobbies and passions. On top of that, I have a couple of friends that have been using Last.fm as well. Basically, the approach I took had three simple high-level steps get the data from last.fmmodel that data into a neo4j graphpump the data into the neo4j database using an import toolquery the data for hours on end So let’s get right to it. Step 1: exporting the data from last.fm. Turns out there are some cool tools out there to get the scrobble data out of last.fm. Step 2: create a model out of this. From this dataset, I then had to create a neo4j graph model. Ok, so I got the data, and got the model – how do I now get it into neo4j? Step 3: import the data This is where it got interesting. So on I went. It was very interesting to see that the import process only took about a minute with Talend, versus more than an hour with my Excel/neo4j-shell method.
JSON Formatter & Validator 8 Regular Expressions You Should Know Regular expressions are a language of their own. When you learn a new programming language, they're this little sub-language that makes no sense at first glance. Many times you have to read another tutorial, article, or book just to understand the "simple" pattern described. Today, we'll review eight regular expressions that you should know for your next coding project. Before we start, you might want to check out some of the regex apps on Envato Market, such as: You can extract emails, proxies, IPs, phone numbers, addresses, HTML tags, URLs, links, dates, etc. Extract, scrape, parse, harvest.

Sample Size Calculator - Optimizely What is Optimizely's Stats Engine? Optimizely's sample size calculator is different from other statistical significance calculators. It is based on the formula used in Optimizely's Stats Engine. How many visitors do I need for my A/B test? This statistical significance calculator allows you to calculate the sample size for each variation in your test you will need, on average, to measure the desired change in your conversion rate. Why is your calculator different from other sample size calculators? Our A/B test sample size calculator is powered by the formula behind our new Stats Engine, which uses a two-tailed sequential likelihood ratio test with false discovery rate controls to calculate statistical significance. With this methodology, you no longer need to use the sample size calculator to ensure the validity of your results. How do I determine the baseline conversion rate? What is Minimum Detectable Effect (MDE)? How do I estimate a value for minimum detectable effect (MDE)?
