Large companies work very hard to make sure their services don’t go down, and the reason is simple — significant outages will hurt your brand and drive customers to competing products with a better track record. 

Building a reliable internet service is a hard technical problem, but for company leaders it also presents a human challenge. Motivating your engineering teams to invest in reliability work can be difficult, because it is often perceived to be less exciting than developing new features.

At scale, incentives dominate. The top tech companies employ thousands of employees and operate hundreds of internet services. Over the years, they have come up with clever ways to ensure their engineers build reliable systems. This article discusses human engineering techniques that have worked at scale across the most successful tech companies in history. You can apply these to your company, whether you’re an employee or a leader.

Spin the wheel

The AWS operational review is a weekly meeting open to the entire company. Every meeting, a “wheel of fortune” is spun to select a random AWS service from hundreds for live review. The team under review has to answer pointed questions from experienced operational leaders about their dashboards and metrics. The meeting is attended by hundreds of employees, dozens of directors and several VPs. 

This incentivizes every team to have a baseline level of operational competence. Even if the probability of an individual team getting selected is low (at AWS, less than 1%), as a manager or tech lead on the team, you really don’t want to appear clueless in front of half the company the day your luck runs out. 

It is important that you regularly review your reliability metrics. Leaders who take an active interest in operational health set that tone for the entire organization. Spin the wheel is just one tool to accomplish this. 

But what do you do in these operational reviews? This brings us to the next point.

Define measurable reliability goals

You would like to have a ‘high up-time’ or ‘five nines’, but what does that really mean for your customers? The latency tolerance of live interactions (chat) is much lower than that of asynchronous workloads (training a machine learning model, uploading a video). Your goals should reflect what your customers care about. 

When you review a team’s metrics, ask them to describe measurable reliability goals. Make sure you understand — and they understand — why those goals were chosen. Then, have them use dashboards to prove that those goals are being met. Having measurable goals will help you prioritize reliability work in a data-driven manner. 

It is a good idea to focus on the detection of issues. If you see an anomaly in their dashboards, ask them to explain the issue, but also ask them whether their on-call was notified of the issue. Ideally, you should realize something is wrong before your customers do. 

Embrace chaos

One of the most revolutionary mindset-shifts in cloud resiliency is the concept of injecting failure into production. Netflix formalized this concept as “chaos engineering” — and the idea is as cool as the name suggests.

Netflix wanted to incentivize its engineers to build fault tolerant systems without resorting to micromanagement. They reasoned that if systemic failure is made to be the norm rather than the exception, engineers have no choice but to build fault-tolerant systems. It took time to get there, but at Netflix, anything from individual servers to entire availability zones are knocked out routinely in production. Every service is expected to automatically absorb such failures with no impact to service availability. 

This strategy is expensive and complex. But if you’re shipping a product where a high uptime is an absolute necessity, then failure injection in production is a very effective way to get something resembling a ‘correctness proof’. If your product needs this, introduce it as early as possible. It will never be easier or cheaper than it is today. 

If chaos engineering seems like overkill, you should at least require your teams to do ‘game days’ (simulated outage practice runs) once or twice a year, or leading up to any major feature launch. During a game day, you will have three designated roles — the first role simulates the outage, the second fixes it without knowing beforehand what was broken and the third observes and takes detailed notes. Afterward, the whole team should get together and do a post-mortem on the simulated incident (see below). The game day will reveal gaps not only in how your systems handle outages, but also in how your engineers handle them.

Have a rigorous post-mortem process

A company’s post-mortem process reveals a great deal about its culture. Each of the top tech companies require teams to write post-mortems for significant outages. The report should describe the incident, explore its root causes and identify preventative actions. The post-mortem should be rigorous and held to a high standard, but the process should never single out individuals to blame. Post-mortem writing is a corrective exercise, not a punitive one. If an engineer made a mistake, there are underlying issues that allowed that mistake to happen. Perhaps you need better testing, or better guardrails around your critical systems. Drill down to those systemic gaps and fix them.

Designing a robust post-mortem process could be the subject of its own article, but it’s safe to say that having one will go a long way toward preventing the next outage. 

Reward reliability work

If engineers have a perception that only new features lead to raises and promotions, reliability work will take a back seat. Most engineers should be contributing to operational excellence, regardless of seniority. Reward reliability improvements in your performance reviews. Hold your senior-most engineers accountable for the stability of the systems they oversee.

While this recommendation may seem obvious, it is surprisingly easy to miss. 

Conclusion

In this article, we explored some fundamental tools that embed reliability into your company culture. Startups and early-stage companies usually do not make reliability a priority. This is understandable — your fledgling company must be obsessively focused on proving product-market fit to ensure survival. However, once you have a returning customer base, the future of your company depends on retaining trust. Humans earn trust by being reliable. The same is true of internet services.

Amazon is rebooting its live-action adaptation of the God of War reboot

Amazon is rebooting its live-action adaptation of the God of War reboot

Amazon is reshuffling the deck with its God of War series. After the success of Fallout, it wants its next Prime Video gaming adaptation to live up to those lofty expectations — and it’s apparently willing to start fresh to do so. Deadline first reported on Thursday that the series showrunner and two executive producers have left the project as the streamer recalibrates “to move in a different creative direction.”

Showrunner and executive producer Rafe Judkins (Wheel of Time) and executive producers Mark Fergus and Hawk Otsby (Children of Men and Iron Man) are no longer involved with the project. Amazon and Sony reportedly praised their screenplays, which suggests the shakeup is more about wanting a fresh take than quality concerns. According to Variety, Amazon plans to hire a new showrunner and put together a new writers’ room to take another stab at a live-action Kratos.

Sony / Santa Monica Studio

The series is an adaptation of the 2018 franchise reboot that shifted the action from Greek to Norse mythology. Amazon’s description should sound familiar to anyone who played the game:

“When his beloved wife dies, Kratos sets off on a dangerous journey with his estranged son to spread her ashes from the highest peak — his wife’s final wish.[The quest] will test the bonds between father and son, and force Kratos to battle new gods and monsters for the fate of the world.”

Amazon Studios is co-producing the series alongside Sony Pictures Television. According to Deadline, Santa Monica Studio creative director Cory Barlog is staying on as an executive producer. Also reportedly remaining are PlayStation Productions’ Asad Qizilbash and Carter Swan, as well as Santa Monica Studio’s Yumi Yang and Vertigo’s Roy Lee.

Why is ‘Adam Driver Megalopolis’ blocked in Instagram searches?

Why is ‘Adam Driver Megalopolis’ blocked in Instagram searches?

When people search for “Adam driver Megalopolis” on Instagram or Facebook right now, instead of seeing posts about Francis Ford Coppola’s latest film, they’re shown a warning, titled, “Child sexual abuse is illegal.”

That bizarre fact was pointed out in a post on X yesterday, and as of today, I’m still seeing it when I search for the phrase. But why? Well, it doesn’t seem to have anything to do with recent Threads moderation failures. Nor are there bombshell revelations about Megalopolis or its main star that I’m aware of.

Yikes.
Screenshot: Instagram

Instead, Facebook and Instagram seem to be blocking searches containing “mega” and “drive” — I saw it when I searched with those two words together, but not when I searched for “Megalopolis,” “Adam Driver,” or either term mixed with any others. The issue isn’t new, either, as this nine-month-old Reddit post about searching for “Sega mega drive” on Facebook illustrates. (That search seems to work as expected, now.)

It’s not clear why the words are blocked and Meta didn’t immediately respond when we asked. Facebook and Instagram have blocked other innocuous-seeming terms, such as “chicken soup,” because distributors of child abuse materials use it as part of their coded language to evade detection on the platforms.

What is Fandango at Home? Here's everything you need to know

There are many great video streaming services that are eager to take your money each month. But what if you’re just not keen on the all-you-can-eat buffet and would simply rather build your digital collection? That’s where Fandango At Home, formerly known as Vudu, comes into play.

While popular video-on-demand (VOD) services like Netflix and Hulu, deliver tons of great content, they come with an associated price tag. In the current era of streaming services, its easy to blow out your budget just because you want access to everything streaming online. However, there is another option. Free advertising-based streaming television (FAST) delivers tons of great programming, and it doesn’t cost you a single penny.

Fandango at Home is one of those FAST streamers, and has a library filled with content available to stream for free. Of course, if they have a movie you just have to have, you can outright buy them and watch anytime, on any streaming device.

Here we dive into what Fandango at Home / Vudu is all about, the prices you’ll see, and the platforms and devices it supports.

From Vudu to Fandango at Home

Vudu Office Logo
Vudu

Vudu was a digital on-demand video service that first arrived as an internet-ready set-top-box, the Vudu Box, sold at Best Buy stores in 2008. However, the company decided to ditch the Vudu Box in favor of digital content sales and delivery through apps installed in Blu-ray players and HDTVs. Walmart acquired the company in 2010 after the retail giant failed to compete against Apple’s iTunes platform.

After several changes and incarnations, including a partnership with UltraViolet (a cloud-based digital movie locker that allowed anyone to unlock digital versions of purchased Blu-rays and DVDs) and Movies Anywhere, in April 2020, Vudu announced that it entered an agreement to be acquired by Fandango Media, a subsidiary of NBCUniversal.

The transition from Walmart to Fandango Media was completed in July 2020, with the full rebrand of Vudu to Fandango at Home happening in 2024.

Is Fandango at Home a subscription service?

No. It’s a digital content delivery platform only. You can create a free account and watch the platform’s free content (with commercials), or purchase content to watch anytime through the Vudu app or a compatible, linked platform. Rentals are available as well.

Layout

Fandango at Home provides a simplified, Netflix-like interface. On the website, categories line along the top: Movies, TV, Free, and My Library. The latter category is where all your purchases and rentals reside. This toolbar also provides a quick tool to redeem a digital copy or code and the means to access your account, settings, device management, and support.

The mobile app’s layout depends on the underlying device.

On iPhone, it includes a toolbar along the top and along the bottom. The latter lists five categories similar to what’s provided on the website: Spotlight, Search, My Library, Free, and Settings. The top toolbar merely lists popular search terms like Rentals, Deals, TV, Horror, Action, Collections, and so on.

On an Android tablet, shown above, only the Home button is available with everything else tucked away in a hidden menu accessible only by a hamburger-style button.

The Xbox app places all categories and search terms along the top. The main toolbar resides at the very top, providing the My Vudu, Spotlight, Free, Movies, TV, Search, and Settings categories. Underneath is the Home button along with specific search terms like Rentals, Deals, Kids, Horror, Franchises, and more.

In all applications, Fandango at Home provides featured media in a sliding tile-based ribbon using general categories like Featured Films, Featured Rentals, Deals of the Week, In Theaters: Films Before DVD, TV Season Sale, Free: Ladies to Look Up To, and more.

Highlight a tile and you have the option to watch a trailer, if available. Click/tap on the thumbnail and you’re led to the content’s page. You can then rent, purchase, or watch the content for free (if available). There are also options to add the content to your Wishlist and to redeem a code.

What content is available on Fandango at Home?

Fandango at Home provides two forms of paid content: Rentals and Purchases. This content is available in three resolutions:

  • SD – 480p
  • HDX – 1080p
  • UHD – 2160p

Rentals

Vudu, theater at home.

The cost depends on the media, but standard rentals range from $1 to $6. For early-access movies that are still in theaters, rental prices will be slightly higher. Some marked with the “Theater at Home” banner hit $20, like Deadpool & Wolverine and It Ends With Us. The video quality does not affect the rental price.

Unwatched rentals are available for 30 days. Once the content begins, you’ll have 24 hours to finish, with unlimited replays during those 24 hours.

Purchases

The info panel for Scream is shown on Vudu.
Jen Karner / Digital Trends

The cost of movies ranges from $5 to $30. Users can view this media anytime through the Vudu app or in some cases other platforms that support Movies Anywhere and UltraViolet. For the most part, while movies are available at different resolutions, you get access to all of them for the same price.

Game of Thrones available for purchase on Vudu.
Jen Karner / Digital Trends

The cost of a single TV episode is $2 to $4. Seasons range from $17 to $44. Again, you can view this media anytime through the Vudu app or in some cases other platforms that support Movies Anywhere or UltraViolet.

Free content

Jen Karner / Digital Trends

Prior to selling the platform in 2020, Walmart introduced Vudu Movies on Us in 2016. This service requires a free account, the Vudu app, or a web browser. It streams movies and TV shows in 1080p with limited commercial interruptions. There are roughly three or four commercial breaks with up to three ads per break, depending on the content.

This content is made available within the platform’s Free section. Selections are also listed on the main page, each marked with a red Free with Ads banner. Click on the content’s image tile followed by the green Watch Free button on the following page.

Customers also have the option to rent or purchase free content, removing advertisements.

This service allows users to scan the UPC code found on Blu-ray and DVD packaging to unlock the digital version. It requires the Vudu app (Android) or a web browser (iOS) and permission to access the mobile device’s camera. For Apple devices, this option can be found under My Library on the website’s menu.

Here are the costs:

  • Blu-ray to HDX – $2 + tax
  • DVD to SD – $2 + tax
  • DVD to HDX – $5 + tax

Code redemption

Many Blu-ray and DVD discs include redemption codes within the packaging. These can be used to unlock digital versions playable through the Fandango at Home app and website. Some are marked with the Play Anywhere logo while others do not — likely older UltraViolet codes that should still work.

To redeem these codes, users can load the content’s Fandango at Home page in the app or website and click/tap the Redeem button. The following page provides a text field to enter the code. Click/tap the Submit button to claim the digital copy.

How to access Fandango at Home

The 2024 Roku Ultra.

Google finally launches the Imagen 3 image model

Google finally launches the Imagen 3 image model

Saying that Google’s road to AI dominance has been rocky would be an understatement. The company’s AI tools have led to several controversies, and one of them involved the company’s image generation model named Imagen. Regardless, it’s pressing forward. Google just released the new Imagen 3 image model.

If you saw Google I/O, then you’ve probably been waiting for this model for several months. The company announced the model during the event. All users had to tide them over in the meanwhile as a large controversy concerning the model producing racially inaccurate depictions of historic figures. Well, that issue has since been resolved. People using Gemini Advanced can generate images of people.

Google finally releases Imagen 3

As with any image generation model, the key focus is realism, and Google has long achieved that goal for the most part, making it a great alternative to DALL-E. However, that doesn’t mean that it can’t one-up itself. As you can guess, Imagen 3 can create images with more detail and fewer artifacts than its predecessor. The images won’t have as much AI jankiness like traumatizing amorphous figures popping up all over the image like we saw from AI-generated images of old. Also, you can expect higher-quality HD images. This is in case you want to zoom into the images for whatever purpose.

One of the main issues plaguing AI images is text generation. We’re used to seeing images of “STTOP” signs and “Bookk” stores. Well, Imagen 3 brings better text generation. You won’t need to worry about messed-up text in the background.

Advertisement

Don’t you hate when you type something like “statue made of glass”, and you get an image of a statue behind a sheet of glass? Well, Imagen 3 comes with enhanced prompt understanding. This means that it will be better able to understand the prompts that you write.

When it comes to safety, Google went the extra mile to filter potentially harmful material, so you won’t have to worry about producing inappropriate images by accident. Not only that, but the company has a watermarking tool that makes it easy to identify that the images are AI-generated.

You can try Imagen 3 out now for free using Gemini. Simply go to the Gemini site or app, and type the type of image you want it to pop out.

How to use a VPN on Fire TV for streaming

How to use a VPN on Fire TV for streaming
The Amazon Fire TV line is very VPN-friendly.

Amazon

If you’ve got a Fire TV video streamer, you already know how great it can be to access all of the major streaming platforms and thousands of shows and movies in one centralized hub. And seeing all your favorites on a big-screen TV is way better than watching it on a smaller laptop or smartphone screen.

But what if you wanted to watch a show or movie and discovered it was unavailable in your country? Or what if you wanted to watch an award-winning BBC documentary but it was only available on the BBC’s iPlayer — and you don’t happen to live in the United Kingdom?

That’s where a VPN (virtual private network) comes in. Using a VPN can let you unlock geo-blocked content for streaming even if you’re outside of a given area. And here’s the best part: Unlike archrival Roku, Amazon’s Fire TV system offers VPN apps straight through its built-in app store. We’ll explain the details and tell you how it works.

For starters, we’re going to assume you have a Fire TV device. If you don’t, we have good news: If your TV doesn’t already have , the add-on devices are frequently on sale at Amazon for as little as $25 or less. Grab the if you want a good balance of price versus performance — just make sure it’s on sale for $40 or less. (See how the Fire TV streamers compare to rivals from Roku, Google, Apple and more by checking out our list of .)

Once you have your Fire TV hardware set up, it’s time to choose a VPN — and that’s where the Fire TV operating system shines. A long list of VPNs, including all of our current top picks for the , are available on the platform and they’re as easy to download and install as any of the video apps.

The Engadget-approved VPNs currently available on Fire TV include:

We’ll leave it to you to research which VPN offers the best combination of features and value for you, but a word of warning: With the exception of the first two listed above, we don’t recommend using a free VPN, as they’re notorious for collecting and selling your data to advertising networks to fund shoddily-protected servers. Note you can install as many VPNs as you’d like on Fire TV, if you’d like to cross-test them at your leisure.

Installing it is easy once you know which Fire TV VPN you want to use. Head to Find > on the main menu and simply search the name of your preferred VPN – just type “VPN” if you’d like to scroll through all of the options available. There, you can find the service you want (or are already subscribed to) and start installing. The process shouldn’t take too long. Once it’s completed, you’re ready to start using it.

Once you’ve downloaded the app, navigate to it on your Fire TV dashboard. You’ll have to enter your username and password or sign up to create an account. Some VPNs might require you to create an account on your smartphone or computer beforehand.

Once logged in, you can either click the “Connect” button on your VPN or browse the server list to choose which country you want to tunnel to. Once connected, return to the Fire TV home screen and reload your streaming platform of choice to verify if the content is different. If it is, your VPN is working and you’re ready to stream.
