Using PGBouncer With CockroachDB

,

PGBouncer is a lightweight connection pooler for PostgreSQL. CockroachDB is a cloud-native SQL database for building global, scalable cloud services that survive disasters.

CockroachDB is a PostgreSQL wire compatible database, which means it aims to have tight compatibility with the PG ecosystem. Today, we’re going to wire PGBouncer to work with CockroachDB. This article is meant to scratch the surface of possibilities unblocked by PGBouncer with CockroachDB and not meant to be an in-depth overview. We’re currently researching this topic and will follow up with official docs on the proper architecture and sizing of PGBouncer and CockroachDB.

Open Source Solution for Building Invincible Apps

,

Introduction

I left Microsoft after 19 years, where I led teams that built system software for highly scalable cloud applications. This included leading development of the Microsoft Orleans framework from its inception at Microsoft Research until it became one of the most successful open-source projects within the .NET ecosystem. Orleans powers a number of large-scale Microsoft systems such as Xbox Game Services, Skype, Azure IoT, Azure ML, Azure Active Directory, and many more cloud services outside Microsoft. So if you’ve ever played online multiplayer games like Halo or Call of Duty, our team built much of the underlying infrastructure that supports it.

When I originally joined Orleans, cloud computing was still in its infancy. We had a 10,000-foot vision and not a single line of actual code. We needed to reimagine how cloud-scale applications should be coded because, at the time, available and high-performance scalable systems were only achievable by experts. And while everyone knew the cloud was coming, we had no idea how to build applications in a way that ensured they would be accessible and productive for millions of software engineers.

How to Draw Directions on a Map in React Native

,

Today we’re going to draw directions route on a map in React Native, showcasing the path between two different locations. We’re going to make use of react-native-maps which is a powerful library, allowing us to draw polylines between multiple coordinates. We are also going to use Google Directions API in order to fetch precise directions routes between two coordinates.

It is important to note that the react-native-maps library as of the time of this writing only officially supports the polyline module on the latest React Native version due to the increasing changes in the React Native ecosystem that are not easy to keep up with.

Exclusive Infographic: WordPress by the Numbers

,

What is WordPress? It began as a simple CMS for building a blog, and it has evolved over the years into a complex ecosystem of tools and resources.

WordPress can power ecommerce sites, interactive courses, art projects, and of course, it powers one or two blogs. Depending on who you ask, WordPress powers between 35% and 40% of the entire web; that makes it one of the most important technologies of the web era. Best of all, it’s free and open-source, so if you’re new to web design, WordPress is a great place to get started.

We’ve put together this simple infographic with all the facts you need to know about WordPress in 2021.

6 Best Ecommerce Solutions for 2021

,

It’s never been easier to set up an ecommerce store and start selling. There are a dizzying array of ecommerce solutions available in 2021, and most are feature-rich and competitively priced.

Ecommerce sites are notoriously difficult to migrate from platform to platform, so more often than not, you’ll be committed to your chosen solution for years. The key when choosing an ecommerce solution to maximize your return on investment, is to consider not just what your business needs today but what it will need tomorrow.

There are two basic approaches to ecommerce. The first is a dedicated platform that handles everything. The second is a plugin that adds ecommerce features to an existing CMS. Both approaches have benefits and drawbacks.

1. Shopify: Best for Almost Everyone

Shopify is a well-known, well-liked, and reliable dedicated ecommerce platform. As a system for getting a business off the ground and selling fast, it is peerless.

Shopify jealously guards developer access, with templates and plugins pre-vetted. Unlike some marketplaces, you can be confident that there are no hidden surprises in your shiny new store.

And because Shopify has passed the point of market saturation, it’s worthwhile for big players to provide their own plugins; credit services like Klarna and shipping companies like netParcel can be integrated with a few clicks.

The admin panel is a touch complex, as Shopify is designed to allow a single account to be linked to multiple stores. But once you’re set up and familiar with where to find everything, it’s a slick, streamlined business management system.

Whenever a client says, “we want to start selling online.” My first thought is, “Shopify.” And for 90% of clients, it’s the right choice.

And that’s where this roundup should end…except there’s still that 10% because Shopify isn’t perfect.

For a start, an all-in-one platform doesn’t suit everyone. If you already have a website you’re happy with, you’ll either need to migrate or lease a dedicated domain for your store.

Shopify’s platform is very secure, which inspires confidence in buyers, but the price of that security is a lack of flexibility in the design.

Then there’s the infamous variant limit. Shopify allows 100 variants on a product. Almost every client runs into that wall at some point. Let’s say you’re selling a T-shirt: male and female cuts are two variants; now add long or short sleeves, that’s four variants; now add seven sizes from XXS to XXL, that’s 28 variants; if you have more than three color options, you’ve passed the 100 variant limit. There are plugins that will allow you to side-step this issue, but they’re a messy hack that hampers UX for both customer and business.

Shopify should certainly be on every new store owner’s shortlist, but there are other options.

2. WooCommerce: Best for WordPress Users

If you’re one of the millions of businesses with a pre-existing site built on WordPress, then adapting it with a plugin is the fastest way to get up and running with ecommerce.

WooCommerce is regularly recommended as “Best for WordPress Users,” which is a back-handed compliment that belies the fact that WooCommerce reportedly powers 30% of all ecommerce stores. If running with the crowd appeals to you — and if you’re using WordPress, it presumably does — then you’re in the right place.

WordPress has a gargantuan plugin range. As such, there are other plugins that will allow you to sell through a WordPress site. The principle benefit of WooCommerce is that as the largest provider, most other plugins and themes are thoroughly tested with it for compatibility issues; most professional WordPress add-ons will tell you if they’re compatible with WooCommerce. If your business is benefitting from leveraging WordPress’ unrivaled ecosystem, it can continue to do so with WooCommerce.

The downside to WooCommerce is that you’re working in the same dashboard as the CMS that runs your content. That can quickly become unmanageable.

WooCommerce also struggles as inventories grow — every product added will slow things a little — it’s ideally suited to small stores selling a few items for supplementary income.

3. BigCommerce: Best for Growth

BigCommerce is an ecommerce platform similar to Shopify, but whereas Shopify is geared towards newer stores, BigCommerce caters to established businesses with larger turnovers.

The same pros and cons of a dedicated ecommerce solution that applied to Shopify also apply to BigCommerce. One of the considerable downsides is that you have less control over your front-end code. This means that you’re swapping short-term convenience for long-term performance. Templates, themes, and plugins — regardless of the platform they’re tied to — typically take 18 months to catch up with best practices, leaving you trailing behind competitors.

BigCommerce addresses this shortcoming with something Shopify does not: a headless option. A headless ecommerce platform is effectively a dedicated API for your own store.

Enabling a headless approach means that BigCommerce can be integrated anywhere, on any technology stack you prefer. And yes, that includes WordPress. What’s more, being headless means you can easily migrate your frontend without rebuilding your backend.

BigCommerce also provides BigCommerce Essentials, which is aimed at entry-level stores. It’s a good way to get your feet wet, but it’s not BigCommerce’s real strength.

If you have the anticipated turnover to justify BigCommerce, it’s a flexible and robust choice that you won’t have to reconsider for years.

4. Magento: Best for Burning Budgets

If you have a development team at your disposal and a healthy budget to throw at your new store, then Magento could be the option for you.

You can do almost anything with a Magento store; it excels at custom solutions.

Magento’s main offering is its enterprise-level solution. You’ll have to approach a sales rep for a quote — yep, if you have to ask the price, you probably can’t afford it. Magento has the track-record and the client list to appeal to boards of directors for whom a 15-strong development team is a footnote in their budget.

That’s not to say that a Magento store has to be expensive; Magento even offers a free open source option. But if you’re not heavily investing in a custom solution, you’re not leveraging the platform’s key strengths.

5. Craft Commerce: Best for Custom Solutions

If you’re in the market for a custom solution, and you don’t have the budget for something like Magento, then Craft Commerce is ideally positioned.

Like WooCommerce for WordPress, Craft Commerce is a plugin for Craft CMS that transforms it into an ecommerce store.

Unlike WordPress, Craft CMS doesn’t have a theme feature. Every Craft Commerce store is custom built using a simple templating language called Twig. The main benefit of the approach is that bespoke solutions are fast and relatively cheap to produce, with none of the code bloat of platforms or WordPress.

Because your site is custom coded, you have complete control over your frontend, allowing you to iterate UX and SEO.

You will need a Craft developer to set up Craft Commerce because the learning curve is steeper than a CMS like WordPress. However, once you’re setup, Craft sites are among the simplest to own and manage.

6. Stripe: Best for Outliers

Ecommerce solutions market themselves on different strengths, but the nature of design patterns means they almost all follow a similar customer journey: search for an item, add the item to a cart, review the cart, checkout. Like any business, they want to maximize their market share, which means delivering a solution that caters to the most common business models.

Occasionally a project happens along that doesn’t fit that business model. Perhaps you’re selling a product that’s uniquely priced for each customer. Perhaps you’re selling by auction. Perhaps you don’t want to bill the customer until a certain point in the future.

Whatever your reason, the greatest customization level — breaking out of the standard ecommerce journey — can be managed with direct integration with Stripe.

Stripe is a powerful payment processor that handles the actual financial transaction for numerous ecommerce solutions. Developers love Stripe; its API is excellent, it’s documentation is a joy, it’s a powerful system rendered usable by relentless iteration.

However, this approach is not for the faint-hearted. This is a completely custom build. Nothing is provided except for the financial transaction itself. Every aspect of your site will need to be built from scratch, which means hefty development costs before seeing any return on investment.

The Best eCommerce Solution in 2021

The best ecommerce solution is defined by three factors: the size of your store, the anticipated growth, and the degree of custom design and features you want or need.

Shopify is the choice of most successful small stores because you can be selling inside a day. For businesses with an existing presence and a smaller turnover, those on WordPress will be happy with WooCommerce. For larger stores planning long-term growth, BigCommerce’s headless option is ideal. Craft Commerce is a solid performer that marries low costs with flexibility for businesses that need a custom approach.

4 Predictions for the Web in 2021

,

The start of the year is always a good time to reassess priorities and consider new approaches, but 2021 is more of a reset than we expected this time last year. 2020 is unlikely to go down in anyone’s autobiography as the best year of their life, but it has done something positive: it’s prepared the ground for rapid change in the next 12 months.

More than any other year in our lifetimes, 2021 is set to be revolutionary, with emerging trends that will last well into the new decade. Here’s what we think you can look forward to around the next corner.

1. The End of Minimalism

Minimalism has been the de facto approach to web design for the last decade because it works.

But design reflects the zeitgeist. Where minimalism once felt clean and fresh, it’s starting to feel dull and uninspired. There have been a few false-starts breaking out of the long-term trend, but thanks to the pandemic, 2021 will be the year minimalism finally folds — at least for a while.

Prior to coronavirus-mandated lockdowns worldwide, there were already signs of a more vibrant, more decorative, more joyful approach to design. Simple typefaces have been replaced with more decorative examples — faces that use ink-traps to fake 3D effects are surprisingly popular.

trends are cyclical, and the wheel always turns

One of the biggest aspects of this blossoming trend is the move away from Material Design-style flat color not just to gradients but to multi-color gradients and even animated gradients. Even Apple, the last bastion of the clean white-box approach, jumped on the gradient bandwagon with its Big Sur branding.

One of the few things COVID-19 hasn’t slowed is the adoption of new web technology, and CSS, in particular, has had some major developments in the last year. CSS Grid is now a practical technology, and our ability to code standards-compliant designs that aren’t dependent on hierarchical boxes is greatly enhanced.

After more than a year of pretty grim news for most people, much of the world will be vaccinated over the next twelve months, and life will rapidly return to normal. The last global crisis on this scale was the 1918 influenza pandemic, and it led directly to the decade known as the Roaring Twenties.

Minimalism was already dipping in popularity — trends are cyclical, and the wheel always turns — but lockdown, or perhaps more precisely the end of lockdown, is the catalyst for significant change.

2. The Decline of WordPress

In Autumn 2020, something entirely unexpected happened: The W3C announced the platform its new web presence would be built on, and WordPress — the previous choice of the web’s steering committee — didn’t even make the list of finalists.

Due to accessibility concerns, the W3C development team opted to migrate away from WordPress to Craft CMS. The decision was met with a mixture of glee and outrage. But whether you agree with the decision or not, it’s hard to see it as anything other than yet another symptom of WordPress’ decline.

WordPress faces a triple threat: there are web builders that do an adequate job for low-end web projects; there are newer rivals like Craft that outperform WordPress as a CMS; there’s a growing interest in alternate approaches, like Jamstack.

So will it all be over for WordPress in 2021? Not even close. There are myriad reasons WordPress will continue to be the choice of designers and developers for years to come. Tens of thousands of professionals worldwide have invested their whole careers in WordPress; there are millions of themes, plugins, templates, and build processes that are tightly woven into the WordPress ecosystem. What’s more, there are millions of sites with substantial content archives powered by WordPress [WebDesignerDepot is one such site].

WordPress reportedly powers approximately 37% of the web, and it will still be the dominant CMS in 2022. But it’s unlikely to grow beyond that 37%, and by 2030 its market share will be in rapid contraction.

2020 was the high-tide mark for WordPress

But for all its faults — and it’s undeniable that WordPress is full of faults — WordPress is the best of the web; it has given a voice to millions of people, launched countless careers, and empowered entrepreneurship worldwide.

2020 was the high-tide mark for WordPress, but it’s not an extinction-level event — even the much-maligned Flash, which was killed dead in a matter of months by the first generation iPhone, limped on until a few weeks ago.

WordPress will have to find a niche and accept a smaller market share; in doing so, it will address the single biggest complaint that anyone has about WordPress: that it’s trying to do too much.

WordPress is one of the great success stories of the web. In a decade, it may have to settle for powering just 10% of the web — a level of failure most of its rivals can only dream of.

3. The Digital Currency Explosion

2021 is undoubtedly the year that cryptocurrency goes mainstream. In 2020 Bitcoin grew by almost 400%; currently valued at around $35k, conservative predictions for a December 2021 valuation are $100k, with five-year predictions as high as $1m. And Bitcoin isn’t the only cryptocurrency; the value of developer-friendly Ether has jumped by more than 50% in the first few weeks of 2021.

In the US, the incoming Biden administration is preparing a multi-trillion dollar relief package, which many believe young Americans will invest in cryptocurrency. Perhaps more importantly, large investment banks are now pumping hundreds of millions in digital currencies. PayPal and Visa are both in the advanced stages of adopting blockchain technology.

The biggest threat to the new digital economy is the volatility of cryptocurrency. You cannot price services in XRP if XRP’s dollar price could crash at any time — as it did a few weeks ago.

And so there are two routes in which this trend will unfold for ecommerce. Either pricing will remain in dollars, and the equivalent price in various cryptocurrencies will be calculated in real-time. Or, transactions will make use of stablecoins like Tether that are tied to the value of the US dollar.

Cryptocurrency is the latest gold-rush, and whether you think it’s the chance of a lifetime or yet another Ponzi scheme, it will become increasingly high-profile in ecommerce throughout 2021.

4. No More Video Calls and also More Video Calls

2020 was the year of Zoom. Its growth from bit-player to overtaking Skype is a material lesson for entrepreneurs that every obstacle is an opportunity.

every obstacle is an opportunity

Over the last year, we’ve discovered two things: meetings are more creative in person, and office costs are significantly reduced when staff work remotely.

There’s going to be a shift in the business landscape this year. Remote working will continue to be normal for years to come as businesses enjoy rent savings. Video calls will still be common for quick update meetings. But expect to travel to physical meeting places periodically for in-depth strategic planning.

Expect to see major cities with deserted office buildings and a rapid expansion of co-working spaces, especially those with meeting spaces — if WeWork can hold on a little longer, there may be light at the end of the tunnel.

As a web professional, you’re in a unique position to thrive in the new business world, even more so if you’re a freelancer. Remember, if you’re working onsite, be mindful of your physical health, and if you’re working remotely, be mindful of your mental health.

What Do You Think?

No one saw 2020 coming. Sometimes world events are outwith our control, and we have to hang on and hope it gets better. It’s been a tough 12 months, and the truth is we’re not through it yet.

But the 2020 coronavirus pandemic is the first pandemic in human history that we’ve had the technology to shorten.

2021 offers the opportunity for enormous change. Will designers look for new, more decorative approaches? Will we replace our technology stack? Will you be billing clients in Ether this year? Will you suffer the misery of a packed evening commute ever again?

How CentOS Became 2020’s Final Victim

,

If you were paying close attention to your IT department around the 8th of December, you might have heard some quiet sobbing and the occasional wail of, “Why? Why?! WHY?!” Now, it was the year 2020, so this might have seemed normal to you, but it’s actually something of a problem that could affect your business: CentOS is pretty much dead.

For the non-total-nerds among us, here’s the skinny: CentOS is a Linux-based operating system, typically used on servers. CentOS has been incredibly popular, and quite a few businesses run on it. But now, that’s changing.

CentOS is a Linux-based operating system, typically used on servers…But now, that’s changing

CentOS used to be released in thoroughly tested versions, the latest being CentOS 8. CentOS 8 was released in September of 2019 and was supposed to be supported for ten years. Now, it’s been decided that CentOS will no longer have versioned releases, opting for a rolling-release style of updates. That means there’ll be one version that constantly gets new software.

That’s cool in theory, but it means the operating system will be less stable overall. Essentially, it’s going to be used as a development branch of / testing ground for Red Hat Enterprise Linux and is no longer its own OS. If you have CentOS-based servers, you should migrate to another OS sooner rather than later.

And I just got my own CentOS-based VPS set up the way I wanted it.

Wait, What Does Red Hat Have To Do With This?

Here’s the short, short version of the history of CentOS: Red Hat (an OS developer) has two Linux distributions of its own and has had for a long time. There’s the free and community-focused Fedora and the business-focused highly expensive Red Hat Enterprise Linux (AKA RHEL).

Funny story: RHEL, despite its expensive licenses, is still mostly made from open source code, which anyone can access and use. And it’s a good OS, particularly for people who like stability.

In 2004, some smart people took all the open-source parts of RHEL and made a brand new, nearly identical operating system with it: the Community Enterprise Operating System, or CentOS. Basically, people could download and use an enterprise-level server OS for free. All the documentation for RHEL was compatible, and you could get support from the community.

It was the perfect alternative for anyone who didn’t have the budget for expensive software licenses.

In 2014, Red Hat offered to partner with the CentOS community. The idea was basically this: “It’s pretty much the same software. If our company and your community work together, both our products will be better! We make our money from enterprise customers, anyway.”

Most importantly, with Red Hat doing a lot of the heavy lifting in terms of updates and support, the CentOS community could focus on growing in other ways.

Red Hat pinky swore [citation needed] that they were in this for the long haul, and CentOS did continue to flourish. You know, until 2020.

Well, So Much For Pinky Swearing

Red Hat must have eventually decided that having a popular free version of its own enterprise software and managing it themselves no less — wasn’t that good for business. So they all but shut the project down.

Well, technically, they just changed how it operated. Instead of producing tested, production-ready versions, CentOS is merely a testing ground for RHEL. It is no longer, in my opinion, a good option for anyone who wants to run a stable server.

Current and Future CentOS Alternatives

So if you jumped on the CentOS 8 bandwagon, what should you put on your physical and virtual servers now? Well, you’ve got options.

Debian / Ubuntu

For those who don’t mind going to a very different kind of Linux, Debian has been the picture of OS stability and sysadmin-friendliness for a long time. If you want more frequent software updates, the Debian-based Ubuntu Server is popular and pretty good.

Oracle Linux

Yes, that Oracle has a RHEL-compatible Linux distribution of its own. But it’s not a clone, exactly. I mean, this is Oracle. It’s set up to use their tools and ecosystem, so I hope you like Oracle products. But hey, the OS itself is free!

ClearOS

ClearOS is another RHEL-compatible OS that’s mostly doing its own thing, though I’m not entirely sure what that thing is. Does the company have some deal with Hewlett-Packard? Anyway, they do have a free community edition and paid editions for home and business use.

The CloudLinux RHEL Fork

This is an upcoming release from the makers of CloudLinuxOS. It looks like they intend to load the new RHEL-based OS with some of their own tools, such as reboot-less server update tech. The first release is intended to be a more or less drop-in replacement for CentOS 8.

Rocky Linux

So the community that made and loved CentOS in the first place is, to say the least, ticked. They are so ticked that Greg Kurtzer (a co-founder of CentOS) has decided to do it all over again by making Rocky Linux and keep it in the community this time.

Again, the goal is to make a re-build of RHEL, a drop-in replacement for CentOS (at least for now). Eventually, the goal is to migrate from CentOS to Rocky Linux as easy as using a single, one-line command. The ETA for initial release isn’t quite set in stone, but I can personally vouch for how hard the community is working.

[See, full disclosure here… after writing this article, I joined the Rocky Linux documentation team.]

So Yeah, You Have Options

Some are out now, and others will be soon. Again, CentOS 8 will be supported until the end of 2021. CentOS 7, weirdly, will be supported until June 2024.

Migration shouldn’t be too complicated. Still, a pain in the rear that we have to do this at all, though.

Heroku and Salesforce: From Idea to App (Part 1)

,

As someone who became a Salesforce developer by accident 10 years ago and parlayed that into a career and business, I’m fully aware of the dividends that investing in continuous learning and brushing up on the latest in my industry can yield.  Even after years of working in the Salesforce ecosystem, earning 11 certifications, and going through several hundred different projects, I’ve found it’s difficult to make the time to keep up with all the new tools and features of modern development (and usually I have the TrailheaDX and Dreamforce conferences each year to get caught up!).  

Due to the COVID-19 travel restrictions, in-person conferences are canceled. However, a new video series piqued my interest. In particular, two Salesforce Developer Advocates, Mohith Shrivastava and Julián Duque, are doing a series on Modern App Development on Heroku/Salesforce.

Leveraging CloudAMQP Within My Heroku-Based SaaS Solution

,

In the « Using Heroku to Quickly Build a Multi-Tenant SaaS Product » article, I documented the foundation for a new SaaS solution that I am building (initially for my sister-in-law) — utilizing the Heroku ecosystem. Using Heroku allowed me to deploy the app quickly, without having to worry about infrastructure, DevOps, scalability when the app gets popular, etc. The « Integrating Twilio Into My SaaS Solution In Heroku » publication provided an example of how easy it is to create a Twilio instance and integrate the solution into my Fitness-based SaaS solution. This current journey has resulted in a feature set that both trainers and their clients have been able to enjoy.

This article is going to focus on invoicing clients for services that have been performed and will utilize messaging solutions within the Heroku ecosystem. The goals of the invoice process are as follows:
