Socratic vs. Euclidean Forms of API Documentation

High Scalability

I was emailing a service about their documentation and while their doc was good, about one particularly tricky concept they told me that once you use it for a while, that’s when you’ll understand it. I realize it’s hard to make good documentation.

Self-documenting Architecture

Strategic Tech

I believe that self-documenting architecture would dramatically reduce one of the big costs in software development. Everybody talks about self-documenting code, but that only applies in the small. Why not self-documenting architecture?

Document Model Support in DynamoDB: Flexibility, Availability, Performance, and Scale.Together at last

All Things Distributed

We are introducing native support for document model like JSON into DynamoDB, the ability to add / remove global secondary indexes, adding more flexible scaling options, and increasing the item size limit to 400KB. Now that we have added support for document object model while delivering consistent fast performance, I think DynamoDB is the logical first choice for any application. NoSQL and Flexibility: Document Model. The DynamoDB team is launching document model support.

Exploring Cross Document Communication

Tim Kadlec

One of the new features that HTML5 offers web developers is a way to send information between documents on different sites via Javascript. Currently for security and privacy reasons, browsers prevent cross site scripting but with HTML5’s Cross Document Messaging, the intention is to allow documents to communicate with each other without sacrificing security. There are two key steps involved with HTML5 Cross Document Messaging.

Connecting MongoDB to Ruby with Self-Signed Certificates for SSL

Scalegrid

In this blog, we’ll show you how to connect to a MongoDB server configured with self-signed certificates for SSL using both the Ruby MongoDB driver and the popular Object-Document-Mapper (ODM) mongoid. The connection options available for the driver are documented here , and the options we will need are: :ssl. We will use a yaml file to provide configuration to mongoid, and the details of such a config file are documented here. These are documented here.

The Performance Inequality Gap, 2021

Alex Russell

Unless a site is installed to the home screen as a PWA , any single page is just another in a series of documents that users experience as a river of links. TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB.

Test Planning Simplified

DZone

In my experiences of planning for testing in various environments, and across several teams and organizations, the value of that planning was never the document itself; rather, it was the thoughts and consideration of the activities, resources and potential risks and issues yet to be discovered. Thinking deeply about all of those things and writing them down, in whatever form the final document took, was the real value of the exercise.

Enterprise Architecture in a Product-Oriented DevOps World

Are Times still Good for Load Testing?

Alex Podelko

One criterion was the existence of ecosystem (documents, expertise, people, services, etc). To evaluate such ecosystems, in absence of more sophisticated data, I used the number of documents Google finds and the number of jobs Monster finds mentioning each product. But when I check it in 2018, JMeter appears to be well ahead of LoadRunner (now MicroFocus) in both the number of documents and the number of jobs mentioning it, apparently becoming the most popular load testing tool.

More fun with fast remainders when the divisor is a constant

Daniel Lemire

To get good results, we can use an important insight that is not documented anywhere at any length: we can use 64-bit processor instructions to do 32-bit arithmetic. In software, compilers can often optimize away integer divisions, and replace them with cheaper instructions, especially when the divisor is a constant. I recently wrote about some work on faster remainders when the divisor is a constant.

For a primer on how to use MongoDB roles, please refer to the documentation – Manage Users and Roles. Index builds on MongoDB production clusters need to be handled with the utmost care. Depending on the size of your data, both foreground and background builds can bring your cluster down.

The Cost of Javascript Frameworks

In fact, it says very little about the performance of the core frameworks in play and much more about the approach to development these frameworks may encourage (whether intentionally or not) through documentation, ecosystem, and general coding practices.

A Comprehensive Guide to Deal With XPath in Selenium

DZone

Locators are Selenium commands used to locate a GUI web element present in the web page Document Object Model (DOM) structure. Selenium has always been the first choice for automation developers to automate their web applications. Locating dynamic web elements has historically been dolorous for automation testers, which brings the scope of XPath into the picture. XPath is one of the most preferable locators provided by Selenium.

Selenium Focus Issues And How To Solve Them

DZone

While performing automation testing in Selenium, your test code or test script could result in erroneous results if it is interacting with a web element that is not yet loaded in the Document Object Model (DOM). Do you know that every website or web application comprises different web pages containing different web elements like buttons, text boxes, progress bars, etc.? However, the web is asynchronous in nature.
