Campendium: A Responsive, Fancy Detail Page

By Steph Skardal
September 9, 2019


This week, I was very excited to deploy a project for Campendium, one of our long-time clients. As noted in my recent post on Campendium updates for the year, Campendium has thousands of listings of places to camp and provides a great infrastructure for the development of a rich community of travelers around North America.

For the past few months, I’ve been working on a significant update to Campendium’s campground detail page, the page template where in-depth information is provided for each of Campendium’s locations. This is equivalent to a product detail page on an ecommerce site.

The “guts” of the update included a new detail page design with expanded responsiveness, the introduction of 360° videos, and expanded user driven content in the form of Question & Answer (Q&A or QnA), reviews, notes, nightly rates, etc. Read on to find out more and see video examples of several of the features!

User Interface & Responsiveness Updates

One of the things the Campendium team and I are most proud of here is the responsiveness of the new design. In the case of traveling and camping, responsiveness is important since a large amount of traffic comes from mobile devices, relative to what you might see in other industries.

User images are shown as “hero images” and the user interface updates depending on the browser device and width, as shown in the following videos for Gilbert Ray Campground and Cayuga Lake State Park.

A second preview of responsive behavior on the campground detail page with embedded maps.

Another updated design usability tweak was a sticky navigation bar to navigation throughout the page, which can get especially long with user submitted content. See how the “Overview”, “Video”, etc. links become sticky as you scroll down on the page, and the current region coming into view of the page is underlined:

Navigation becomes fixed to the top of the browser as a user...

National Braille Press Releases Redesigned Website

End Point congratulates National Braille Press on the recent release of their redesigned website, launched earlier this week! National Braille Press (NBP) supports the blind and low-vision community with events, initiatives, resources, children’s programs, and a bookstore. NBP has been working with End Point since 2002 and hosts and maintains their website, which is based on the Interchange open-source ecommerce platform.

Project Phases

End Point started working with NBP on this redesign project in late 2017. We began with a user experience (UX) review & content strategy project which resulted in design directives for our in-house team. Design and plans were completed in mid-2018 and implementation began then. End Point built a new, more powerful search feature and developed a number of ‘cornerstone’ pages while NBP staff worked tirelessly in-house to convert the rest of the pages on their website to the new designs.

Leveraging NBP In-House Resources

NBP’s wide reach in their community and long history means their website has hundreds of content pages. This can be costly to convert, and for some non-profits, can make a redesign project cost-prohibitive. End Point engineers Greg Davidson and Marco Pessotto worked alongside NBP staff helping them learn the Bootstrap web development toolkit and the steps they needed to take to integrate each page into the new designs. Using these in-house resources dramatically reduced the overall project cost while allowing the content to be converted carefully by hand with accuracy and care.

WCAG 2.0, AA Standard

NBP’s user base is heavily centered in the low-vision community, so compliance with user accessibility standards was a main focus of the redesign effort. End Point worked with NBP to make sure all of the engineers on the project were trained in the Web Content Accessibility Guidelines (WCAG 2.0) AA standards and guidelines. Testing for compliance was done with AXE and WAVE Chrome accessibility plugins. NBP also...

Fix for cdparanoia segmentation fault

Compact disc close-up Photo by Alberto Cabrera, cropped, CC BY 2.0

It had been a while since I last needed to rip a CD into audio files (and compress them), but the need recently arose. This particular disc was a language learning supplement to a book, and a CD was a reasonable way to distribute that.

(Even though audio file downloads and streaming have become a far more common way to distribute audio than physical CDs, electronic formats don’t preserve our same rights to resell, lend, and make backups. But that is a topic for another blog post!)

I was ripping the CD with abcde (A Better CD Encoder), a text-based CD ripping, tagging, and compressing front-end I have used often in the past. Unexpectedly I got an error, as shown in this terminal output:

The Dollars and Sense of Hiring Software Consultants

By Elizabeth Garrett Christensen
August 16, 2019

I’m often asked by family and friends about End Point’s market and how software consulting fits into the business landscape and I thought I’d write up some thoughts for the general public in how hiring a consultant is actually the smartest thing to do for your business and it makes a ton of sense financially.

Let’s talk some math about hiring an in-house developer:

  • According to Glassdoor, the average software developer salary is around $50,000–$120,000. Let’s say $85,000 per year. You typically pay for health insurance, other benefits and overhead expenses, so let’s just round the total cost of hiring one person to $110,000 per year (I think that’s actually pretty conservative).

  • You’d probably need to hire two people to support anything essential to your business, since having a single developer is risky (illness/​vacation/​employment change, etc.).

  • Your total cost of getting two developers in-house is around ~$220,000 per year

Hiring your own developers Software consulting agency
Senior developers
Diverse skillset ?
Protection from staffing changes
Flexible budget
Staff up and down easily

Consulting Instead of Hiring

  • Spending less: You could spend $40,000–$50,000 a year in consulting and get excellent coverage, including new feature development and support for your project. Some of our customers even spend substantially less than that.

  • Skillset: Were you able to hire two people that know all of your software stack? Can they work on your CRM/​inventory system and do your website? Can they troubleshoot issues with your Windows Active Directory setup? Are they senior developers with a decade of experience? Or did you have to hire junior developers who need to train up on your project?

When you’re working with an End Point team, you’re able to get expert advice on the parts of your system that...

How to set up a local development environment for WordPress from scratch

By Kevin Campusano
August 7, 2019


I recently got pulled into a project for a client who wanted to have a new WordPress website developed for them. I started by setting up a development environment with the niceties that I’m used to from my other application development work. That is, a development server, interactive debugging, linting, and a good editor.

Another thing that I wanted was not to have to deal with LAMP or WAMP or XAMPP or any of that. I wanted a clean, from scratch installation where I knew and controlled everything that was there. I’ve got nothing against those packages, but I think that, by setting up everything manually, I’d be able to better learn the technology as I would know exactly how everything is set up under the hood. The shortcuts could come later.

Luckily for me, there aren’t many pieces when it comes to setting up a basic, running development environment for WordPress. You only need three things: 1. MySQL, 2. PHP, and 3. WordPress itself. I also wanted a few other goodies and we’ll get there.

Let’s go through the steps that I took to set all of this up:

1. Set up PHP

In Ubuntu, installing PHP is easy enough. Just run the following command:

sudo apt-get install php

After that’s done, run php -v to validate that it was successfully installed. It should result in something like this:

PHP 7.2.19-0ubuntu0.18.04.1 (cli) (built: Jun  4 2019 14:48:12) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.2.19-0ubuntu0.18.04.1, Copyright (c) 1999-2018, by Zend Technologies

There’s one particular PHP extension that we’re going to need. Let’s install it with:

sudo apt-get install php-mysql

The php-mysql extension is necessary for our PHP installation to interact with MySQL. That’s all that’s needed to run WordPress as far as PHP is concerned.

2. Set up MySQL

WordPress uses MySQL for all of its data storage concerns. So, let’s install it. Again, in Ubuntu, installing and setting up MySQL...

A Moon Landing and the Education of Our Children

By Jonathan Perlin
August 6, 2019

Cosmosphere Museum

As Liquid Galaxy flows from city to city, a big museum in small-town Kansas welcomes its newest exhibit to the collection. Amidst authentic NASA artifacts and real remnants of the space program, an array of seven screens glows in the shadow of the full-size replica of the lunar module that put man on the moon. In the wake of the 50th anniversary of the monumental mission, Liquid Galaxy arrives right on time to educate and awe patrons of all ages.

A family exploring the Liquid Galaxy

“Jim and I had a great time experimenting with it...and while we were doing so, we talked with three different guests—one couple and two singles—who said how much they appreciated us adding it. What Jim and I appreciated was the variety of content that we can see teachers using when they have classes here.” —Mimi Meredith, VP of Development, Cosmosphere Museum, Hutchinson, Kansas

In the initial stages of installation, passersby cocked their heads in curiosity as large displays were lifted onto their mounts and the form of Liquid Galaxy emerged. The scene dramatically changed as the screens came to life and images of Earth and the Moon flew across the screen to the delight of children and adults alike. Witnessing the joy and wonder of these museum guests was by far the most rewarding aspect of participating in the installation. But it also got me thinking about the education of our children. To see kids get excited about science, space travel, and engineering was refreshing and ultimately a wonderment to witness. Just as we had Liquid Galaxy up and running a crew of space camp cadets rounded the corner and we smiled as their eyes widened.

Immediately a barrage of questions: What is it? Where did it come from? How can you use it? Can we play games on it? But the biggest question I heard among the volley was: What can we learn from it?

This question not only overwhelmed me with a sense of joy, but also instilled a feeling of hope for our planet’s future. Inquisitive by nature, children remain...


Campendium v2019: A Summary of Recent Updates

By Steph Skardal
August 5, 2019

This year has brought a handful of exciting changes for Campendium, one of End Point’s long-time clients, by yours truly. Created by campers for campers, Campendium has thousands of listings of places to camp, from swanky RV parks to free remote destinations, vetted by a team of full-time travelers and reviewed by over 200,000 members. I thought I would take some time to summarize these recent updates.

Maps and Clustering

Campendium map clustering of campground locations

Campendium uses Mapbox for map rendering to display campgrounds and locations throughout North America. One of the new features added this year was clustering of campground locations, where campgrounds are grouped together and presented in a “cluster” with a size relative to how many campgrounds are in the cluster.

If a user is searching for campgrounds in a broad location, they can see where campgrounds might be more densely grouped by location. Once a user zooms in zoom in a couple of clicks, the campgrounds are no longer clustered and individual campgrounds locations can be seen. While working on this update, we spent a good amount of our time tweaking and troubleshooting the optimal clustering behavior to provide the most benefit to those searching for a campground. Mapbox GL JS works in parallel with ReactJS, and runs with a Ruby on Rails back-end.

Campendium map non-clustering of campground locations after zooming in

Advanced Filtering

Campendium advanced filtering

Another exciting was the introduction of advanced filtering in the search interface, presented in combination with map display. Users can filter campgrounds by category (e.g. Public Land, RV Parking, Parking, Dump Station), filter by price (with a slider), hookups, campground policy (e.g. age or pet restrictions), discounts, recreation, and facilities. All of this search filtering is driven by Sunspot, a Ruby on Rails gem for working with the popular Solr search engine. Results can be sorted by user provided reviews, price or distance from a specific GPS location. Here, much care was given to provide the best user interface for presenting this valuable functionality...

Prepare for .NET Core 3 and .NET 5

By Juan Pablo Ventoso

Prepare for .NET 5 Photo by Caspar Camille Rubin on Unsplash, edited by Juan Pablo Ventoso


It’s been a while now since .NET Core is out there: It was released back in June 2016 and it kept growing since then. The main advantages when comparing with .NET Framework is that .NET Core is free, open-source and cross-platform. It also has several performance improvements that gains up to 600% increase for some particular functions like converting elements to a string, or more than 200% for some LINQ queries, and a general performance boost in application startup.

But it also has drawbacks: Some third party libraries are still not fully supported, so while they can still be used, the compiled results will only be portable to Windows. Also, .NET Core 2.2 (the latest release to date) doesn’t yet have support for Windows Presentation Foundation (WPF) or Windows Forms applications... But it looks like this is going to change soon.

Next stop: .NET Core 3

In the 2019 Build Conference that took place in May, .NET Core 3 was announced: It’s expected to be released in November this year, and it will finally include support for Windows desktop development (WPF, UWP and Windows Forms). It will also include Entity Framework 6, since most existing Windows Forms and WPF applications use that framework to access data.

.NET Core 3 features and tools

.NET Core 3 will also include support for IoT (Internet-of-things) applications, aiming for internet-enabled devices like smart locks or glasses, and will allow AI development through ML.NET (an open-source machine learning framework built for .NET). For those who can’t wait and want to try it out before its release, previews are available to download.

Game changer: .NET 5

In the same conference, on May 7, Microsoft also announced that they are planning to release a new platform for building applications targetting all devices and operative systems in november 2020: .NET 5. And while it will be based on .NET Core, the word “core” will be removed because Microsoft is...
