Popping Out of Hidden Overflow The following is a guest post by Agop Shirinian. Agop ran into an interesting scenario where he needed an element to be scrollable in one direction, while allowing the overflow in the other direction. You'd think that's what overflow-x and overflow-y are for, but it's not that simple. I'll let Agop explain. So you're tasked with creating a scrollable menu with submenus that pop out when you hover over a parent menu item. A successful Git branching model » nvie.com Note of reflection (March 5, 2020)This model was conceived in 2010, now more than 10 years ago, and not very long after Git itself came into being. In those 10 years, git-flow (the branching model laid out in this article) has become hugely popular in many a software team to the point where people have started treating it like a standard of sorts — but unfortunately also as a dogma or panacea.During those 10 years, Git itself has taken the world by a storm, and the most popular type of software that is being developed with Git is shifting more towards web apps — at least in my filter bubble. Web apps are typically continuously delivered, not rolled back, and you don't have to support multiple versions of the software running in the wild.This is not the class of software that I had in mind when I wrote the blog post 10 years ago. Why git? ¶
JPA Tutorial Java persistent API is a specification and set of interfaces that helps with persistence of java objects into the database. It has been created after success of object relational mapping frameworks - the most popular is Hibernate. JPA defines standard basic set of features that every object relational mapping framework should have. Almost all current O/R frameworks implement JPA specification. Of course, most of them have additional features to set them apart.
Getting Started · Building a RESTful Web Service In Spring’s approach to building RESTful web services, HTTP requests are handled by a controller. These components are identified by the @RestController annotation, and the GreetingController shown in the following listing (from src/main/java/com/example/restservice/GreetingController.java) handles GET requests for /greeting by returning a new instance of the Greeting class: package com.example.restservice; import java.util.concurrent.atomic.AtomicLong; import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.RestController; @RestControllerpublic class GreetingController { private static final String template = "Hello, %s!"
Cookie-based Authentication in AngularJS Single Page Apps are ruling the world and AngularJS is leading the charge. But many of the lessons we learned in the Web 2.0 era no longer apply, and few are as drastically different as authentication. Depending on where you build and release your AngularJS app, there are different ways to handle authentication and I hope this post clears some of that up. 9.1: libpq - C Library This documentation is for an unsupported version of PostgreSQL. You may want to view the same page for the current version, or one of the supported versions listed above instead. libpq is the C application programmer's interface to PostgreSQL. libpq is a set of library functions that allow client programs to pass queries to the PostgreSQL backend server and to receive the results of these queries.

Getting Started · Building an Application with Spring Boot If you are building a web site for your business, you probably need to add some management services. Spring Boot provides several such services (such as health, audits, beans, and more) with its actuator module. If you use Gradle, add the following dependency to your build.gradle file: implementation 'org.springframework.boot:spring-boot-starter-actuator' If you use Maven, add the following dependency to your pom.xml file: <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>
A JavaScript library for building user interfaces A Simple Component React components implement a render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. How to recursively remove .svn directories Regular readers may have clocked onto the fact that I use Subversion. Well the way it works it to keep a hidden set of directories within your checked out repository. It uses this to track any changes etc.. Each directory is called ‘.svn’ and is within each and every directory and subdirectory you have.
pyp - Python Power at the Prompt ls | pyp "p.replace('maybe','yes') | pp.sort() | pp[1:3] |p , p , p.strip('abc') | whitespace | p[3], 'no' | p.upper() " Pyp is a linux command line text manipulation tool similar to awk or sed, but which uses standard python string and list methods as well as custom functions evolved to generate fast results in an intense production environment. Pyed Pyper was developed at Sony Pictures Imageworks to facilitate the construction of complex image manipulation "one-liner" commands during visual effects work on Alice in Wonderland, Green Lantern, and the The Amazing Spiderman. Because pyp employs it's own internal piping syntax ("|") similar to unix pipes, complex operations can be proceduralized by feeding the output of one python command to the input of the next. This greatly simplifies the generation and troubleshooting of multistep operations without the use of temporary variables or nested parentheses.
Easier Nested Layouts in Rails 3/4 A layouts recap Any non-trivial web application will have multiple HTML layouts. For example, a login page may use a simple layout with no header and footer, whereas authenticated pages will have navigation bars and breadcrumbs. Public pages like documentation and privacy policy may use yet a different layout. Rails offers a basic solution for this in the form of layout templates. Create a layout file with the boilerplate you need, then yield to the actual dynamic content that is being rendered:
X-Ray Goggles X-Ray Goggles allow you to see the building blocks that make up websites on the internet. Activate the goggles to inspect the code behind any webpage, then remix elements with a single click, swapping in your own text, images and more. You can build: Sony Pictures Imageworks - Open Source - Scala Migrations Scala Migrations is a library to manage upgrades and rollbacks to database schemas. Migrations allow a source control system to manage together the database schema and the code using the schema. It is designed to allow multiple developers working on a project with a database backend to design schema modifications independently, apply the migrations to their local database for debugging and when complete, check them into a source control system to manage as one manages normal source code. Other developers then check out the new migrations and apply them to their local database. Finally, the migrations are used to migrate the production databases to the latest schema version.
