Data analysis can be reduced to a minimum and data centers can be more sustainable
.

Faster total time to insights is kinder to the environment.

Executives face more pressure than ever to reduce their environmental impact. Because of their contribution to global heating, this is particularly true for data centers. If all data centers around the globe were a nation, they would rank fifth in terms of energy consumption. In 2020, data centers consumed about 1% of the global electricity demand and contributed to 0.3% of all CO2 emissions.

Today companies must disclose their carbon footprint and it is up to data centers to improve their efficiency ranking. There is a list of data centers around the world raked by PUE (price usage effectiveness) and Greenpeace has created a cleantech industry ranking of centers based on their carbon footprint.

The need for greener codes

Many of the sustainability initiatives in data centers are based upon using renewable energy to cool or optimizing cooling systems for lower power consumption. The amount of electricity consumed depends on how the software is used. How much? It’s quite a lot.

Based on current research, one large machine learning (ML) model, such as Meena, consumes the same amount of energy as a passenger vehicle that drove 242,231 miles. Researchers at the University of Massachusetts at Amherst estimated that training a large deep-learning model produces 626,000 pounds of CO2, equal to the lifetime emissions of five cars.

This has led to a greater interest in creating code that is more efficient. The Green Software Foundation (GSF), with members such as VMware, Microsoft, Accenture and GitHub, has a mission to design, architect and code software that consumes less energy.

Tips for sustainable machine learning

There are many academic articles on how to create greener algorithms for AI/ML models. Here are some basic tips.

Minimizing the number of experiments is one way to decrease computing resources. Pre-trained ML models and blueprints are available in hundreds. Developers only need to use their data to embed AI capabilities into applications. This significantly reduces the time it takes to create and train models.

It’s important to see the algorithm’s carbon footprint to be able to make informed decisions about how to optimize performance. Tools have been developed by researchers from many universities. For example, Green Algorithms calculates your cloud computing carbon footprint. Another example is CodeCarbon, which is a software package that integrates into the Python codebase and estimates the amount of CO2 produced by the computing resources used to execute the code.

Automation is also a way to shorten the training time. You can reduce the number of experiments and/or analyze more data while maintaining accuracy. More efficient data sampling by itself can speed up model run time by a factor of 5.8.

The software used to perform the calculations can help reduce the computing resources needed. Databases that are specifically designed to process large amounts of data can optimize storage and memory utilization to lower energy consumption. These databases have the advantage of not having to limit the data being analyzed. This reduces the chance of models becoming inaccurate by trying to speed things up.

Reducing model time and increasing energy efficiency can help reduce total time to insight for business-critical applications like fraud detection, cybersecurity solutions and quality control. A more efficient code is better for the environment and also for your business.

More potential customers are looking for transparency about a company’s green policies. A code “green” standard might be a good first step. Employees are looking for companies that care about the environment and make responsible decisions. Cloud vendors may be required to have visibility into the carbon footprint of a workload and could face fines for processing that is excessive or unnecessary.

With the many calculations needed to determine meaning in order to make better business decisions and be socially responsible, it’s not a luxury but a necessity.

Nothing announces official launch date for new Ear (stick) AirPods alternatives

Nothing announces official launch date for new Ear (stick) AirPods alternatives

True to form, Nothing has just announced the full reveal date for its upcoming audio product, Ear (stick). 

So, an announcement about an announcement. You’ve got to hand it to Carl Pei’s marketing department, they never miss a trick.

What we’re saying is that although we still have ‘nothing’ conclusive about the features, pricing or release date for the Ear (stick) except an image of another model holding them (and we’ve seen plenty of those traipsing down the catwalk recently), we do have a date – the day when we’ll be granted official access to this information. 

That day is October 26. Nothing assures us that on this day we’ll be able to find out everything, including pricing and product specifications, during the online Ear (stick) Reveal, at 3PM BST (which is 10AM ET, or 1AM on Wednesday if you’re in Sydney, Australia) on nothing.tech (opens in new tab)

Any further information? A little. Nothing calls the Ear (stick), which is now the product’s official name, “the next generation of Nothing sound technology”, and its “most advanced audio product yet”. 

But that’s not all! Apparently, Ear (stick) are “half in-ear true wireless earbuds that balance supreme comfort with exceptional sound, made not to be felt when in use. They’re feather-light with an ergonomic design that’s moulded to your ears. Delivered in a unique charging case, inspired by classic cosmetic silhouettes, and compactly formed to simply glide into pockets.” 

Opinion: I need more than a lipstick-style case

It’s no secret that I want Nothing’s earbuds to succeed in world dominated by AirPods; who doesn’t love a plucky, eccentric underdog? 

But in order to become some of the best true wireless earbuds on the market, there is room for improvement over the Nothing Ear 1, the company’s inaugural earbuds. 

Aside from this official ‘news’ from Nothing, leaked images and videos of the Ear (stick) have been springing up all over the internet (thank you, developer Kuba Wojciechowski) and they depict earbuds that look largely unchanged, which is a shame. 

For me, the focus needs to shift from gimmicks such as a cylindrical case with a red section at the end which twists up like a lipstick. Don’t get me wrong, I love a bit of theater, but only if the sound coming from the earbuds themselves is top dog. 

As the natural companions for the Nothing Phone 1, it makes sense for the Ear (stick) to take a place similar to that of Apple’s AirPods 3, where the flagship Ear (1) sit alongside the AirPods Pro 2 as a flagship offering. 

See, that lipstick case shape likely will not support wireless charging. That and the rumored lack of ANC means the Ear (stick) is probably arriving as the more affordable option in Nothing’s ouevre. 

For now, we sit tight until October 26.

YouTube could make 4K videos exclusive to Premium subscribers

You might soon have to buy YouTube Premium to watch 4K YouTube videos, a new user test suggests.

According to a Reddit thread (opens in new tab) highlighted on Twitter by leaker Alvin (opens in new tab), several non-Premium YouTube users have reported seeing 4K resolution (and higher) video options limited to YouTube Premium subscribers on their iOS devices. For these individuals, videos are currently only available to stream in up to 1440p (QHD) resolution.

The apparent experiment only seems to be affecting a handful of YouTube users for now, but it suggests owner Google is toying with the idea of implementing a site-wide paywall for access to high-quality video in the future.

So, after testing up to 12 ads on YouTube for non-Premium users, now some users reported that they also have to get a Premium account just to watch videos in 4K. pic.twitter.com/jJodoAxeDpOctober 1, 2022

It’s no secret that Google has been searching for new ways to monetize its YouTube platform in recent months. In September, the company introduced five unskippable ads for some YouTube users as part of a separate test – an unexpected development that, naturally, didn’t go down well with much of the YouTube community. 

A resolution paywall seems a more palatable approach from Google. While annoying, the change isn’t likely to provoke the same level of ire from non-paying YouTube users as excessive ads, given that many smartphones still max out at QHD resolution anyway. 

Of course, if it encourages those who do care about high-resolution viewing to invest in the platform’s Premium subscription package, it may also be more lucrative for Google. After all, YouTube Premium, which offers ad-free viewing, background playback and the ability to download videos for offline use, currently costs $11.99 / £11.99 / AU$14.99 per month.

Suffice to say, the subscription service hasn’t taken off in quite the way Google would’ve hoped since its launch in 2014. Only around 50 million users are currently signed up to YouTube Premium, while something close to 2 billion people actively use YouTube on a monthly basis. 

Might the addition of 4K video into Premium’s perk package bump up that number? Only time will tell. We’ll be keeping an eye on our own YouTube account to see whether this resolution paywall becomes permanent in the coming months.
