Solr Quick Start¶ Overview¶ This document covers getting Solr up and running, ingesting a variety of data sources into multiple collections, and getting a feel for. What are Environment Variables? Environment variables are global system variables accessible by all the processes running under the Operating System (OS).

Ronald Bradford . These include (and are not limited to) the planning game, short and frequent iterations, testing, frequent refactoring, continuous integration, ownership and standards. Identifying the problem. These core principles however are not the full lifecycle of software development. It is also ensuring full product ownership and responsibility consistently. It is also ensuring that in a larger organization, compatibility and consistency can occur with other products. Scheduling lifecycle management time.

Development and engineering resources already apportion time between planning, development and unit testing. There needs to be a second more important consideration. What about across multiple applications in your organization. The compounding benefits can mean less code to view by developers and thus adding incremental efficiency. Less code to deploy also means smaller installation and application footprint. Engineering teams in general are more focussed on delivering new functionality or fixing issues with newer functionality rather than reviewing existing functionality for optimization, consolidation, replacement or removal. This is a proactive measure to look at the features of the technology in use.

This is a different type of refactoring, but the same concept in code reduction. A great example here is the use of an iterator design pattern rather than a loop. Unfortunately this is an all to common occurrence.

• OMSA is a web based application to manage DELL PowerEdge Servers. Using OMSA you can perform proactive system monitoring, system diagnosis, troubleshoot hardware.

Module bloat. An assessment of the technology stack for a newly deployed application (i. What was needed to operate the system was actually documented. What was needed was actually automated to assist in future deployments. This improved the time to deploy new application servers. Framework bloat. An education based client faced a huge problem.

The existing system had grown over a number of years, the engineering department had grown from one developer to over a dozen developers, yet the approach towards software development had not changed from that single developer original module based Drupal approach for a small application. I also generally quote one of my popular lines — “When reviewing the performance of a piece of code (or SQL statement); the first objective should not be to make it better; the first objective should be to eliminate it.” This is also generally received with blank stares and silence. An analysis of the user registration process unveiled alarming result. This analysis that can happen in a very short period, e. They wanted a more abstract approach, they wanted a magically sharded solution were simply throwing H/W (and $) at the problem made it go away without changing the engineering mindset. In the startup ecosystem this is also known as a successful catastrophe.

Would that not indicate the problem exists elsewhere in the codebase. Further assessment of this one code path demonstrated that when an optimal schema design was architected for the purpose of the application, the number of SQL statements would be reduced to 5 (i. It is a silent reward that their given experience, knowledge and expertise has an unknown financial value to an organization.

Lifecycle Management. It can be difficult to understand the impact of code in the full lifecycle of a software product in the 2. Automated provisioning, Paa. S and CI/CD tools seamlessly enable more (abstract) code to be written to provide that essential functionality to the end user. Automated testing has replaced design documents.

Organizations developer systems without is a data model? All of these tools and techniques however do not replace the intelligence needed to operate a system over time, particularly for tasks including upgrades and integrations. One simple concept can be implemented to assist in all contributors owning lifecycle management. The first is the responsibility of a developer being paged when a production problem occurs due to the line of code they wrote.

This is taking the XP principle of ownership and defining the time dimension to a period infinitely greater than the present iteration. The following is a great tweet that shows this developer has heard of commenting their code, but not considering lifecycle management?

This potential cost in lost productivity could not be justified. This information is rarely documented as a historical artifact and the reason why steps were taken cannot be inferred from what is presently the state of the current code (or even reviewing the code revision history).

This code results in being more efficient and the carryover effect is the developer is actually more effective at writing more subsequent code.
