VTech hack exposes data of hundreds of thousands of kids

Lorenzo Franceschi-Bicchierai writing for Motherboard:

The personal information of almost 5 million parents and more than 200,000 kids was exposed earlier this month after a hacker broke into the servers of a Chinese company that sells kids toys and gadgets, Motherboard has learned.

The hacked data includes names, email addresses, passwords, and home addresses of 4,833,678 parents who have bought products sold by VTech, which has almost $2 billion in revenue. The dump also includes the first names, genders and birthdays of more than 200,000 kids.

Troy Hunt provided some insight on the VTech process to gather the data: informations are sent over plain HTTP, no SSL involved. Passwords are digested with MD5, not even salted. The information of the children and their parents are easily linkable.

The Wordpress blog platform gains a new admin interface based on Node.js

From the Wordpress developer site:

The new WordPress.com interface is built from the ground up as a single JavaScript application that relies on the WordPress.com REST API to communicate to the WordPress core.

The source is open and hosted on GitHub. A desktop Mac App is available that lets you manage all your WordPress.com and Jetpack-enabled sites in one place.

The next big challenge for chipmakers is AI

Stacey Higginbotham writing for Fortune:

Nvidia announced two new graphics accelerators Tuesday, which are aimed at helping large companies like Facebook, Baidu and Google develop new deep learning models and then deploy those models at a massive scale without requiring huge, expensive banks of servers all hooked up to their own power plant.

The article references the new Tesla M40 and Tesla M4 chips. It also points to IBM’s synaptic chip, which, I think, is much more interesting than building AI on top of a CUDA architecture.

Ars Technica reviews Ubuntu 15.10

Scott Gilbertson writing for Ars Technica:

The most exciting thing in Ubuntu 15.10 is probably the updated kernel, which is now based on the upstream Linux Kernel 4.2.

The 4.2 line brings support for recent Radeon GPUs and some new encryption options for ext4 disks. There’s also support for Intel’s new Broxton chips, which just might be finding their way into an Ubuntu Mobile device at some point. 15.10 marks the first time that the new live kernel patching has been available in Ubuntu, and this release adds a new kernel for the Raspberry Pi 2 as well.

Meet TensorFlow, the general purpose machine learning algorithm from Google

Less than a month after unveiling RankBrain, Google now open sources TensorFlow the second generation of its general purpose machine learning algorithm DistBelief. From the white paper:

TensorFlow is an interface for expressing machine learning algorithms, and an implementation for executing such algorithms. A computation expressed using TensorFlow can be executed with little or no change on a wide variety of heterogeneous systems, ranging from mobile devices such as phones and tablets up to large-scale distributed systems of hundreds of machines and thousands of computational devices such as GPU cards.

BTW, it looks like Apple has trouble getting top AI researchers working for the company.

How an iOS developer built his first game for Apple TV

Alexander Repty is a seasoned iOS developer who never had a chance to code a video game. After having published his first game to the Apple TV app store (Cosmos — Infinite Space), he is now telling his story: learning spritekit, putting his hands on an Apple TV Developer Kit (eventhough he was not picked by Apple to get one in the first place), having some people to test his game, setting the price, passing the app store review process (which was painful), providing some sales figures and the lessons he learnt.
