Comparing Graph Databases

#artificialintelligence

A relational database has a ledger-style structure. It can be queried through SQL, and it is what most people are familiar with. Each entry is composed of a row in a table. Tables are related by foreign-key constraints, which is how you can connect one table's information to another, like the primary keys. Slow multi-level joins are often involved when querying relational databases.


Researchers discover lock- screen exploit in iOS 13 just a week before software is to be released

Daily Mail - Science & tech

A final beta version of Apple's iOS 13 was found sporting some pretty major flaws just a week before the operating system is set to be released on devices everywhere. As reported by The Verge, researcher Jose Rodriguez discovered a flaw that enables one to access a phone's list of contacts by initiating a FaceTime call. Once a call is placed, Rodriguez shows how, using the voice-over accessibility feature through the iPhones virtual assistant, Siri, all of the contacts in the phone can be accessed, revealing email addresses, phone numbers, names, and any other information stored in the phone's contact list. The flaw, which Rodriguez reported to Apple in July after examining public betas of iOS 13, is similar to one found by the researcher in the operating system's predecessor, iOS 12.1. Though iOS 13 has yet to be released, betas of the new operating system have been available for months, meaning anyone who downloaded the preliminary versions has been unknowingly walking around with the glitch in their device.


AI passes Go: where next for China's artificial intelligence ambitions?

#artificialintelligence

In July 2017, China published its Next Generation AI Development Plan. As analysts such as Jeff Ding of Oxford University point out, it was not a green-field programme. It rather sought to gather and focus a diverse set of existing initiatives in response to what local academics called a'Sputnik moment': the 2016 defeat of the world's best Go player, Lee Sedol, by a Google-owned AI. For context, China's AI industry was estimated to be worth around RMB15bn (£1.7bn) when the plan was released. The plan often provokes sceptical responses outside China but the country has made significant advances toward the 2020 goal (indeed large parts of it have arguably already been achieved).


GM's Search for In-Car Tech Lands on Google

#artificialintelligence

In the ongoing war for control of the digital space that is the modern car, Google just conquered a major swath of territory. This week, it and General Motors announced that the tech giant's Android operating system will underpin the infotainment systems in GM's cars, starting with some model year 2022 vehicles. For future Chevy, Cadillac, Buick, and GMC drivers, that means built-in access to Google Maps and the ability to use Google Assistant to make calls, send texts, tune the radio, and more, without plugging in their phones. For GM, it's an admission that people don't want its house-made infotainment tech, and to give them what they do want. For Google, it's more direct access to more consumers--GM accounts for 17 percent of new car sales in the US--in the rare place where they're not supposed to have their phone in their hand.


10 Essential Data Science Packages for Python

#artificialintelligence

Interest in data science has risen remarkably in the last five years. And while there are many programming languages suited for data science and machine learning, Python is the most popular. Scikit-Learn is a Python module for machine learning built on top of SciPy and NumPy. David Cournapeau started it as a Google Summer of Code project. Since then, it's grown to over 20,000 commits and more than 90 releases.


"Alexa, roll down the windows!" Inside Amazon's quest to get in your car

#artificialintelligence

The demo house Amazon built inside one of the towers at its Seattle headquarters to show off its Echo smart speakers has a new room, and an important one: a garage. Inside the garage is a concept electric car--or, more specifically, the immobile insides of such a vehicle--that Amazon uses to show automakers the full spectrum of things its Alexa Auto software platform can do. That includes in-car versions of typical Alexa tasks such as audio streaming, messaging, voice calls, and reminders. And because it's a car, Alexa can also do things like roll the windows up and down and control the cabin temperature, all at the verbal request of the driver. Amazon has been working hard on Alexa Auto for the past two years.


The future of food: Why farming is moving indoors

#artificialintelligence

A car park opposite the infamous New York City housing estate where rapper Jay-Z grew up seems an unlikely place for an agricultural revolution. Ten shipping containers dominate a corner of the Brooklyn parking area, each full of climate control tech, growing herbs that are distributed to local stores on bicycles. This is urban farming at its most literal. The containers are owned by Square Roots, part of America's fast-expanding vertical farming industry, a sector run by many tech entrepreneurs who believe food production is ripe for disruption. The world's best basil reputedly comes from Genoa, Italy.


Hey, Siri, how about some shortcuts to help save me some time. Siri says, 'Sure'

USATODAY - Tech Top Stories

Who wouldn't like to get more done in less time? That's the idea behind Siri Shortcuts, a popular Apple app for iPhone and iPad, and built into the upcoming iOS 13 operating system, out in beta release now with a full upgrade due this fall soon after new iPhones hit in September. As the name suggests, Siri Shortcuts link the voice-controlled personal assistant you already know with time-saving shortcuts for tasks you want to perform. By simply asking for it – or tapping the screen if you're not in a place to freely use your voice – your iPhone or iPad can quickly heed your request. In other words, Siri Shortcuts – previously known as Workflow – fuses small actions to yield big results.


#292: Robot Operating System (ROS) & Gazebo, with Brian Gerkey

Robohub

ROS, which stands for Robot Operating System, is a set of software libraries and tools that help you build robot application; Gazebo is a 3D robotics simulator. ROS and Gazebo are both open source and are widely used in the robotics community. Gerkey explains ROS and Gazebo and how they are used in robotics, as well as some of the design decisions of the second version of ROS, ROS2. Brian Gerkey is the CEO of Open Robotics, which seeks to develop and drive the adoption of open source software in robotics. Before Open Robotics, Brian was the Director of Open Source Development at Willow Garage, a computer scientist in the SRI Artificial Intelligence Center, a post-doctoral scholar in Sebastian Thrun's group in the Stanford Artificial Intelligence Lab.


Should we worry about the robots and mind-reading apps remaking our world? Alex Hern

The Guardian

Technology changes so fast that our lives are radically different from even a decade ago, yet slowly enough that sometimes we don't even notice the changes. We live in the future, in other words, and sometimes it takes a moment to realise what an odd, and perhaps unsettling, future it is. So I'm going to try laying it out for you in plain English. Not one, but two, controversial billionaires have created projects aimed at reading minds. Elon Musk, the South African co-founder of PayPal, unveiled the latest step in his plan to build mind-reading implants two weeks ago.
