Développement Dirigé par l'Observabilité pour LLMs

Développement Dirigé par l’Observabilité pour LLMs

,

Le développement dirigé par l’observabilité (DDO) est une approche innovante pour améliorer le développement et le déploiement des logiciels à base de microservices et de logiciels légers (LLMs).

Notre industrie est à ses débuts d’une explosion dans le logiciel utilisant les MLM, ainsi qu’une (séparée, mais liée) révolution dans la façon dont les ingénieurs écrivent et exécutent du code, grâce à l’intelligence générative.

Data is the key to unlocking the potential of this new world. Without data, LLMs and generative AI are nothing more than empty promises. Data is the fuel that powers the engine of ML-driven software development. It is the lifeblood of our industry, and it is essential that we understand how to use it effectively.

Nous sommes à l’aube d’une explosion du logiciel utilisant des modèles d’apprentissage automatique (MLM) et d’une révolution de la façon dont les ingénieurs écrivent et exécutent le code, grâce à l’intelligence artificielle générative.

De nombreux ingénieurs logiciels rencontrent pour la première fois les MLM, tandis que de nombreux ingénieurs en apprentissage automatique sont directement exposés pour la première fois aux systèmes de production. Ces deux types d’ingénieurs se retrouvent plongés dans un nouveau monde déroutant – un monde où un problème de production particulier qu’ils ont peut-être rencontré occasionnellement dans leur carrière est maintenant au centre de l’attention.

Les données sont la clé pour déverrouiller le potentiel de ce nouveau monde. Sans données, les MLM et l’intelligence artificielle générative ne sont rien de plus que des promesses vides. Les données sont le carburant qui alimente le moteur du développement logiciel basé sur l’apprentissage automatique. C’est le sang vital de notre industrie et il est essentiel que nous comprenions comment l’utiliser efficacement.

How to Use AR in Brand Experiences

,

AR (Augmented Reality) continues to build as one of the most exciting technology innovations to appear in recent years. More accessible than virtual reality experiences, since no specialist headset is required, AR has quickly emerged as a crucial tool for building unique experiences.

Although interest in AR as a tool for customer interaction and experience has been growing, demand has skyrocketed in recent years. In addition, since the pandemic of 2020, companies no longer have the same in-person opportunities available to create meaningful relationships with customers.

To ensure a client is fully invested in your brand today, you need to find a new way of building that emotional link. As an immersive, experience-led solution for brand building, AR can improve a company’s chance of earning brand loyalty. What’s more, around 71% of consumers say they would shop more often if AR technology were available.

The question is, how do you develop your own AR branded experiences?

Creating Branded Experiences in AR

For an augmented reality experience to be effective, you need more than just the right technology; you need a strategy for how you’re going to engage, empower, and support your target audience.

The best AR branded experiences aren’t just multi-dimensional advertisements; they’re tools intended to engage, inform, and entertain your audience in a new, highly immersive realm. Before you can begin to work on your AR app, you need to think about what kind of branded experience you want to develop. Here are some excellent examples to get you started.

AR Try-Before-You-Buy Interactions

Globally, ecommerce sales are growing at an astronomical pace. Going forward, there’s no question that the digital landscape will become the new platform for shopping and transactions. But, unfortunately, there are some limitations when it comes to shopping online.

While the right website developer or designer can create a stunning site packed with information about a product or service, there’s only so much that a webpage can do. Delivering a truly immersive user experience for your target audience involves replicating the kind of in-person experiences they would get in a digital format.

The best example of this is the “try-before-you-buy” AR app. Most commonly seen in the clothing and beauty industries, this app allows customers to use AR filters to see what everything from a new hair color to a shade of lipstick might look like on them. The experience is highly accessible and engaging because it builds on customers’ familiarity with filters and similar effects on social media channels like TikTok and Instagram.

A popular example of an AR try-before-you-buy experience comes from Sephora, with the “Virtual Artist” application. Originally installed within the Sephora app in 2016, the technology uses Modiface to scan and track the eyes and lips of the customer using a smartphone camera. After that, the system can overlay eye-shadows, lipsticks, and other products, to give the customer idea of what they might look like in real-life.

As AR applications become more mainstream, new solutions are emerging for companies concerned about things like privacy. Consumers who don’t want to load their image into a system for try-before-you-buy experiences can still access the benefits of AR with the right tools.

For instance, ASOS created the new “See My Fit” service in 2020 to help customers shop for clothing during the pandemic. The solution allows users to see what clothing will look like on a model with a similar body type to their own. This helps to show shoppers how products realistically look in similar bodies while reducing the risk of returns.

ASOS certainly saw the benefit of this innovation, with an increase in revenues of around 24% in the six months leading to the end of February 2021.

AR for Product Catalogs and Visualization

We all remember what it was like to flick through the glossy pages of a magazine or catalog for our favorite stores. Unfortunately, in today’s digital age, these paper brochures are far from the most efficient tool for shopping. We need a more digital experience that allows us to select products, see what they will look like, and add them to our virtual baskets.

One excellent example of how companies can use AR to improve the overall shopping and visualization experience for customers comes from Home Depot. The brand was one of the first to upgrade its user experience strategy with a new Project Color application in 2015. Although this app might seem a little outdated by today’s standards, it’s still an excellent insight into what companies can do to improve their customer’s brand experience.

The Home Depot app used AR to scan a room and implement the color a customer chose for their walls into that space, considering things like furniture, shadow, and lighting, to allow for a more realistic insight. The app has updated significantly over the years to become increasingly immersive.

Visualizing products in a real, contextual space is hugely beneficial for a customer’s purchasing experience and perception of a specific brand. If your customer sees buying the right product from you as simple and convenient, they’re more likely to stick with your organization long-term.

The product catalog and visualization approach to AR in brand development has grown increasingly popular in the last two years, perhaps driven by the demand for more online shopping opportunities. In 2020, Wayfair announced the release of an updated version of its “View in Room” app, which now uses LiDAR technology to provide enhanced utility when shopping for home products.

According to Wayfair, the LiDAR technology and “RealityKit” software give customers a more authentic and realistic view, so they can make better decisions about what they want to buy. According to Apple, customers are 11 times more likely to buy an item of furniture if they have seen how it looks in their home using AR.

Creating Unique Brand Experiences

AR is one of the technology innovations in our current landscape, helping blur the lines between digital worlds and reality. In a future defined by the rise of the metaverse, AR could have a significant impact on how we spend our time in a more virtual world.

Already, companies are taking advantage of this, with things like virtual pop-up shops and temporary experiences intended to differentiate their brands. For instance, Machine-A, a London-based concept store, is usually committed to showcasing contemporary fashion designs.

When it became apparent that London fashion week for 2020 would be virtual, Machine-A came up with a virtual boutique enabled by AR. By scanning a QR code embedded into billboards and posters across London, users could enter the boutique virtually from their phones and experience the designs themselves.

The concept created by Machine-A has opened the minds of countless business brand teams and marketers to new methods of increasing engagement and awareness among customers. In a world where you can’t necessarily interact with your top customers in person, providing them with a new and immersive experience can be a great way to generate loyalty.

The companies more willing to invest in innovative solutions like AR are also more likely to stand out as innovators in their field. Other companies have experimented with similar “pop-up” experiences and unique ways to capture audience attention. For example, Burberry placed a QR code in a Harrods store, which customers could scan to visit a branded experience, where an Elphis statue walked around in their surroundings through the lens of their smartphone camera.

It’s even possible to use AR experiences to attract the attention of new audience groups. For instance, the retail brand, Pull & Bear launched an AR game created with Facebook to help the company reach the 90% of Gen Z customers who identify as “gamers.”

Provide New Levels of Customer Support

As many of today’s businesses know, memorable branding isn’t just about having the right image or website; it’s also about providing the correct level of customer service and support. Most purchasing and brand loyalty decisions made today are based on customer experience.

Providing customers with unique experiences to improve their shopping journey is sure to make your company stand out in the new digital age. But it’s also possible to go even further with AR in your brand CX strategy too.

Amazon Salon, for instance, the first bricks-and-mortar hair salon created by Amazon, was partially established to test new technology. The “point and learn” service, for example, allowed customers to point a product they were interested in on a display or shelf and immediately access educational content. Users could also scan QR codes to visit the product page on the QR site.

This helps customers immediately get to the product they want to buy without relying on input from human services agents. In a similar vein, AR could be an excellent way to onboard a customer, learning how to use a new product for the first time.

Imagine having a user’s manual your customer can enjoy scanning through, thanks to AR technology. All your customer needs to do is scan the QR code on the back of a product, and they can see the item they need to build or install coming to life in front of them. This reduces the risk of customers having to call for help from tech support and means clients can see the value in their purchases a lot faster.

Companies can embrace AR as a virtual learning experience, helping users collect information and learn how to do things through an immersive first-hand experience. This kind of immersive technology could help to make any brand stand out as more user-experience-focused. Even car companies could essentially provide their customers with a complete virtual HUD showing them how each button and dial on their dashboard works.

Upgrade Website Design

Perhaps the most common way companies will be using AR to create branded experiences today is by updating their website. You’ve probably already seen examples of AR being used in a host of retail sites, with new experiences designed specifically for the age of augmented reality.

360-degree images, for instance, allow customers to essentially “look around” a product, and see it from different angles, just like they would if they were looking at the item in-store. We can see an excellent example of this on the BMW build-your-own web page, where vehicle browsers can see their vehicles from every angle.

The 360-degree product viewing experience lets you check everything from the side molding to the sculpted edges in perfect detail.  

QR codes and app downloads can also allow customers to take their AR experience even further, looking at things like what life would be like behind the wheel of one of these virtually augmented vehicles.

As AR becomes more commonplace and the tools available for designers in this arena continue to expand, there will be even more opportunities available to bring AR into the website experience. Even essential website upgrades today might include allowing customers to upload pictures of themselves or their homes, then using augmented reality technology to implement parts of a product catalog into the space.

AR Virtual Events

Finally, when it comes to exploring all the unique ways you can build a better brand experience and excellent customer relationships with AR, it’s worth looking at the event space. The event landscape has struggled significantly over the last couple of years. The pandemic forced most live events to be canceled, and although the post-pandemic era holds new hope for upcoming in-person experiences, the landscape will be very different.

Going forward, most companies plan to avoid a complete shift back to in-person events by creating “hybrid” experiences and augmented reality events instead. Augmented and virtual reality tools allow customers to step into an event arena from wherever they are.

For instance, the Pot Noodle Unilever brand hosted a virtual alternative careers fair in AR, where people could use their phones to navigate through a range of graduate employer booths. The unique career fair experience was designed to replace the more common in-person interactions graduates might have as they approached the end of their education.

The custom-developed 3D booths featured a range of different employers, and students could tap on the booth screen they were interested in to see a video from each employer. As an added bonus, the connection to the Pot Noodle AR careers fair website meant that students could also instantly apply for any of the jobs they were interested in.

Similar events could help brands recreate some of the meaningful experiential experiences that their customers have been missing out on in the last couple of years. They could also act as a valuable tool for bringing together people in a hybrid event, where someone visiting an in-person demo table could scan a QR code to send virtual demonstrations of a product back to their team.

This would reduce the number of people who needed to be present in an event environment at any given time, reducing the risk of health issues.

Bringing Brands to Life with AR

In the new consumer landscape, brand relationships are more important than ever. As a result, customers are making more careful choices about who they purchase from, based on their understanding of that company’s values and differentiators.

Now that you won’t always have an opportunity to interact with customers in-person to earn their trust, AR could be the solution for a lot of companies in search of new engagement tools. All you need to do is figure out how you’ll leverage all the benefits AR can offer.

Will you be creating an app, building a new website with enhanced 360-degree photos, or designing in-person experiences? Hopefully, these examples have inspired you to start exploring your options.

Wix Vs WordPress: 3rd Round Knockout

,

Over the last fortnight one site builder has gone toe-to-toe with another, as Wix launched a marketing campaign aimed at attracting WordPress users, and instead attracted universal ire.

First, Wix sent out expensive headphones as gifts to key WordPress “influencers” in an attempt to lure them to the platform. Second, they produced a series of adverts that instead of promoting their own product, tried to imply that WordPress is so bad you’ll need mental health counselling to cope with it; it’s been widely frowned upon, but am I alone in thinking they’re not a million miles away from Apple’s anti-Windows adverts? No, I’m not.

Then, Wix made an attempt to go viral with an uncomfortable video in which a character portraying “WordPress” releases a “secret” message warning the community of “fake news” supposedly due to be released by Wix. The language and the styling is clear: WordPress is unhip daddio.

Unlike WordPress, Wix is a publicly owned company, it has an obligation to its shareholders to maximize its revenue. Had Wix targeted WordPress’ many failings, that would have been fair game. Had they gone after Shopify, or Webflow, or Squarespace, or one of the many other site builders on the market no one would have blinked an eye. Wix’s error wasn’t going after WordPress, or even the tactics used to do so, Wix’s mistake was in attacking the very community it was attempting to court.

I’m not a big fan of WordPress. I’ve built around a dozen sites in it over the years and we’ve never got along, WordPress and I. But I am a big fan of the ethos of WordPress; who doesn’t love free, open source software, built by volunteers?

The holy grail of marketing is transforming customers into evangelists — individuals who will bare their chests, paint their face with woad, and charge headlong onto social media at the merest hint of a perceived slight. You can’t buy them. It’s a loyalty that has to be cultivated over years, and requires more give than take. WordPress has those evangelists, people who see their careers in web design as intertwined with the CMS. No amount of free headphones is going to convert them to a closed system like Wix.

The irony is that Wix’s approach stemmed from the WordPress community itself. If it is going to celebrate “powering 40% of the Web” then it has to expect to make itself a target. If you’re an antelope, you don’t douse yourself in bbq sauce and strut around the waterhole where the lions like to hang out.

If the row rumbles on, it will eventually end in an apology and a promise from Wix to “do better.” But the truth is, all Wix did was confuse a community of people trying to build websites, with a competing business.

This time next year, Wix will still be recovering from the damage to its reputation, and WordPress will be telling us it powers 110% of the Web.

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?

3 Essential Design Trends, October 2020

,

Design can make a statement. It evokes feeling and can encourage thought and conversation. That’s the common theme among the three trends in website design this month.

Each trend is rooted on the time and place where we live and includes elements that provoke thought. Kudos to these designers and design teams for jumpstarting conversations. Here’s what’s trending in design this month.

1. “Taking a Stance” Design

From social to environmental issues, design projects are echoing the sentiments of their audiences and organization in a way that take a stance on an issue.

Once taboo, this is becoming increasingly used as a technique for brands who are no longer worried about turning off a certain segment. The goal is to rally the core audience and people who feel the same way about an issue or cause.

There’s also a secondary thing happening here. Some designs aren’t really position based, but use imagery and language that resonates with a movement to associate with that feeling.

Never Heart uses “Join the Revolution” and a dark image with a heart to tug at your feelings. It can help create an association to a cause that you believe in without stating that cause directly. The design feels strong and inviting while making you feel like part of something.

Skye High uses “powerful” twice in the headline to convey a particular messages to women. The agency is looking to work with “powerful” women. It’s a timely statement and message that could resonate with a lot of business-women at various levels of their careers.

Discovered Wildfoods is a brand that is rooted in sustainability. The corporate model and responsibility of the brand shows through in the website. This type of design helps connect people with mutual feelings to the brand and products.

It’s refreshing to see more websites and brands embracing social causes and issues. It can be tricky for a number of reasons. But for some brands, it pays off.

2. Abstract Art Elements

If you are worried about a lack of images, or not sure how to portray images in an appropriate way due to the worldwide pandemic – groups or not, masked or not – abstract art elements can be the solution.

Widely used for startups and apps, more abstract design elements are everywhere. It’s an easy way to create strong visual interest without photography.

The most common use of abstract art elements is often in the form of geometric shapes with animation. This is something that almost anyone can understand and simple shapes and movement can be quite stunning when done well.

The good news is this aesthetic can work for almost any type of website. Try it for a redesign when you don’t have photography that feels appropriate in the current environment or if you want to create focus for content that drives website visitors to the words or scroll. This works with more abstract concepts when they are simple and help you move quickly from the visual to text.

Here’s how each of the examples handles abstract art elements:

Indicius uses bouncing circles that move toward text and down the screen to drive users to the headline and scroll action.

With Code uses a fun fuzzy circle with different animations to draw you in.

Appimized uses bright color and a monotone scheme with geometric shapes to sell its services.

3. Images That Make You Think

This might be the most visually interesting, and thought-provoking, website design trend we’ve seen in a while. These designs all feature images with a little something different or unusual that make you think.

There are a lot of different ways to do this – marry photographs and illustrations, create imaginary imagery, animations or effects, visual tricks that play on depth perception or create pseudo-3D effects.

The commonality is that the visual is so striking and unusual that website visitors stop and engage with the design. What do the “oddball” visuals mean? What message do they convey? How did they do that?

All of the questions could be associated with this different style of visual representation.

Bling uses a combination of a photo with illustrated animated elements to draw the eye. The yin and yang between reality and fantasy is quickly evident and makes you want to know more. (It doesn’t hurt that the animation uses dollars and lightning.)

Kibun is interesting because the photo choices create an optical illusion of depth. It matches the content of the design well because the website features artistic textile panels with an artistic design. The illusion is in the angles and coloring of photographs and their placements on the screen. The only downside of this design is that it loses the artistic panache on mobile because the images stack.

Oddball images can sell. We Are Mad stands out because it uses a contrived image, but doesn’t go oversized with it. The more subtle placement is ideal and arguably more attention-grabbing.

Conclusion

Website design can be a powerful thing, as these trends and examples show. Don’t discredit the power of choices in color, imagery, animation, and text when creating a digital experience. Design can mean a lot of different things depending on the audience as these examples show.

At the same time, these design trends are powerful and meaningful. They provide context into our world, our time, and our feelings. Don’t be afraid to experiment and make a statement with your design work. Just remember to keep in mind all potential impacts (positive and negative) before taking the project live.
