Previously sitting in Redshift, Deliveroo’s data has now been moved to Snowflake’s cloud data warehouse.The company, who’s infrastructure sits on AWS, had decided to move due to a number of problems that had begun to arise with its use of Redshift, partly caused by the company’s rapid growth, it grew by 650% last year.Henry Crawford, head of business intelligence at Deliveroo, told CBR: “We had collectively experience with it in previous organisations before Deliveroo and had similar problems.The concurrency problem for example, for a company aggressively growing, to have a known and obvious bottleneck in getting info out to the company, it’s the definition of not being scalable, and it wasn’t for a lack of trying.Earlier in the year at the AWS Summit in London the company revealed that it deals with 17 terabytes of compressed data, 1.8bn historical events, has 450+ active Looker users, and deals with 7000 warehouse queries per hour, and the daily count is said to be much higher.Crawford said that around 90% of employees have access to the data and use tools such as Looker regularly, meaning that every single user will be using data to improve performance.

For a lot of us, though, while personalization can make the considerable amount of time we spend scrolling through social feeds more entertaining, most of the automated personalization we encounter on a day-to-day basis is not necessarily requested – and is wider spread than one might initially think.Essentially, the focus of providing and consuming content that is closely aligned to your preferences results in the creation of a bubble or chamber, restricting your view of the wider picture.As our internet ecosystem has evolved, we have shared increasing amounts of personal data with services we use every day, from social networks to search engines.Google in particular has gradually increased the extent with which it tailors results to the user with innovations like Hummingbird and RankBrain, the inclusion of social results in search, and semantic search.To many users this personalization of search results is helpful and convenient, but an increasing number of users are disturbed by the extent to which the sites they encounter are being shaped by forces outside of their control.Disclaimer: If you want to be completely free of Google’s filter bubble, the only real way is to stop using Google.

Hurricanes get a bad wrap.If they're not destroying people's houses, they're uprooting Barney's Bowl-A-Rama.But these blustering cyclones can also carry more positive side effects: they can bring about some seriously sunny weather.As Hurricane Gert comes close to ending as it moves across the Atlantic Ocean, the aftermath of the storm is likely to bring heat and humidity to the South of England.While the UK's Met Office expects weather in the North of England, Northern Ireland, and Scotland to remain patchy, the South will likely see an upswing in temperatures as a result of Gert.Indeed, the agency is expecting temps to rise up to 25C (77F) towards the end of the weekend, with meteorologist Charlie Powell predicting "tropical and humid" conditions in parts of Southern England.

Imagine someone remotely controlling your brain, forcing your body’s central processing organ to send messages to your muscles that you didn’t authorize.It’s an incredibly scary thought, but scientists have managed to accomplish this science fiction nightmare for real, albeit on a much small scale, and they were even able to prompt their test subject to run, freeze in place, or even completely lose control over their limbs.Thankfully, the research will be used for good rather than evil… for now.The effort, led by physics professor Arnd Pralle, PhD, of the University at Buffalo College of Arts and Sciences, focused on a technique called “magneto-thermal stimulation.” It’s not exactly a simple process — it requires the implantation of specially built DNA strands and nanoparticles which attach to specific neurons — but once the minimally invasive procedure is over, the brain can be remotely controlled via an alternating magnetic field.When those magnetic inputs are applied, the particles heat up, causing the neurons to fire.The study, which was published in the most recent edition of the journal eLife, includes experiments where were performed on mice.

A chunk of code found in the Kronos bank-fraud malware originated more than six years before security researcher Marcus Hutchins is accused of developing the underlying code, a fellow security researcher said Friday.The conclusion, reached in an analysis of Kronos published by security firm Malwarebytes, by no means proves or disproves federal prosecutors' allegations that Hutchins wrote Kronos code and played a role in the sale of the malware.Shortly after his arrest in Las Vegas two weeks ago, the Tweet resurfaced, and almost immediately it generated speculation that the malware Hutchins was referring to was Kronos.An analysis of Kronos soon showed that one portion used an instruction that was identical to one included in the code Hutchins published in January 2015.The same technique in the two code chunks—and the same instruction—was published in 2009 and "both authors learned it from other sources rather than inventing it."Legitimate software uses hooking for a variety of reasons—for instance, so an antivirus product can scan e-mail before it's read.

That's especially true for those in the throes of a 9-to-5 life, tethered by a corporate leash that doesn't afford them the luxury of time or travel.It's straightforward -- build a converting offer.When you can create an offer that converts, then optimize that conversion rate, you could almost infinitely scale your ad spend and continue to churn a profit, effectively making money while you sleep.The sale happens over time, by building a relationship with the consumer, and by constantly feeding them value and ensuring that whatever it is that you're peddling, it solves a problem and alleviates some pain points.Consider things like PDF checklists, free ebooks, trial memberships, and so on.Oftentimes, a small tweak in your headline can lead to massive results.

Although China’s e-commerce industry is growing at a rapid rate, industry experts point to offline infrastructure as a future bottleneck unless more investment is made in this area.Online retail sales in mainland China amounted to 5.156 trillion yuan (US$764.85 billion) in 2016 – equal to 3,729 yuan per capita – up 26.3 per cent from sales in the previous year, according to the country’s National Bureau of Statistics.From 2007 to 2016 the sector grew at a compound annual growth rate of 67.2 per cent.More than 60 per cent of Tmall International’s orders are fulfilled via the bonded online shopping model, according to the mall’s operator Alibaba, which owns the South China Morning Post.For consumers, the bonded model provides buyer protection and shortens delivery times, while for customs it reduces the number of directly shipped packages that must be handled and, in theory, cuts the number of untaxed parcels entering the country, according to Alibaba.“I am positive on the e-commerce trend but it is obviously more complicated than just supply and demand,” said Tammy Tang, executive director of industrial services in China for Colliers International.

Replacing it, the ubiquitous QR code-based mobile payment solutions operated by internet giants like Alibaba and Tencent.Alipay and WeChat Pay, the two third-party payment tools that nearly split China’s mobile payment market, are pushing the trend.When tapping overseas markets, both companies chose the soft landing approach through easy entry points in Chinese outbound tourists.Like in China, the two firms are diligently forming local partnerships to promote themselves as a commercial solution.Since 2015, Alipay’s operator Ant Financial invested a series of local e-wallet and fintech startups including Paytm (India), Kakao Pay (South Korea), Mynt (the Philipines), Ascend Money (Thailand), and HelloPay (Singapore).From Alibaba’s perspective, it’s more appropriate to define the initiative as the globalization of Ant Financial’s whole financial ecosystem, of which Alipay is just one part, according to the Ant Financial spokeswoman.

Dating site OkCupid made the unusual move of announcing that it had given a single member a "lifetime" ban on Thursday—and naming him—in order to make a point."We were alerted that white supremacist Chris Cantwell was on OkCupid," the company wrote at its official Twitter account on Thursday.Cantwell was the subject of a Vice documentary about the white-supremacist Unite The Right marches in Charlottesville, Virginia, over the past weekend, where he offered numerous racist and threatening comments while acting as a march organizer and riding in a car alongside former KKK Grand Wizard David Duke.("We're not non-violent," Cantwell offered at one point in the documentary."We'll fucking kill these people if we fucking have to.")In announcing this ban, OKC also asked its users to be vigilant about any other active members of hate groups found on the site.

When staff at CyberKeel investigated email activity at a medium-sized shipping firm, they made a shocking discovery."Someone had hacked into the systems of the company and planted a small virus," explains co-founder Lars Jensen.Whenever one of the firm's fuel suppliers would send an email asking for payment, the virus simply changed the text of the message before it was read, adding a different bank account number.The firm was launched more than three years ago after Mr Jensen teamed up with business partner Morten Schenk, a former lieutenant in the Danish military who Jensen describes as "one of those guys who could hack almost anything".The consequences of suffering from the NotPetya cyber-attack for Maersk included the shutting down of some port terminals managed by its subsidiary APM.Breaking into a shipping firm's computer systems can allow attackers to access sensitive information.

New Star Wars movies will be in theaters in a handful of months, but Disney is already looking years into the future.According to sources who have surfaced, the next standalone Star Wars movie will center around Obi-Wan Kenobi, though who will be playing him hasn’t yet been determined.The sources claim that Oscar-nominated Stephen Daldry has been tapped to direct the next movie.The information comes from The Hollywood Reporter, which says it was alerted to the plans via sources claiming the deal is very early in its existence.No script for the movie has been written, and it sounds like Daldry hasn’t been completely guaranteed as director.The roles of Obi-Wan Kenobi have previously been played by Alec Guinness and Ewan McGregor.

After long years of research, your efforts have paid off: the archaeological site you’re digging in has turned up a stash of rare, striking bones, no doubt the beginning of a groundbreaking discovery.Only then, you find the KFC wrapper, revealing that this “ancient burial ground” is just the leftovers of someone’s lunch.In the summer of 2015, scientists on Twitter started describing research mishaps like this—which happen more often than you’d think—as “fieldwork fails.” The fieldworkfail hashtag went viral, and two years later, it’s getting an encore in a new book by French illustrator Jim Jourdane (available for pre-order later this year), thanks to his blog and a successful Kickstarter campaign.As Jourdane reveals in Fieldwork Fail, things often don’t go as planned in science.The book contains fieldwork mishaps from the fun and harmless, like realising the “bat” you thought you were tracking was actually a crosswalk signal, to the more dangerous, like peeing on a jaguar’s marked tree and getting stalked through the jungle for three weeks.It’s a great starting point for scientists to communicate some of the less-sexy aspects of their work.

A new set of render images (along with the accompanying video) of the upcoming Sony Xperia XZ1 Compact model leaked earlier today and we’re here to… spread the news as always.We’re talking about a device that has long been rumored to make its first official appearance during Sony’s IFA press conference on August 31.It should be joined by the aforementioned XZ1, but also the mid-range Xperia X1.As you can possibly figure out by its name, this new XZ1 model is small (compact) with a small display but unfortunately not smaller bezels as the company doesn’t seem quite ready yet to implement such a technology to its phones.Nokia is another OEM that seems to love bezels – as their newly unveiled Nokia 8 yesterday comes with huge bezels.According to the latest rumors however, the XZ1 Compact is said to come with a 4.6-inch touchscreen, with the following dimensions: 129.5 x 64.5 x 9.4 mm.
