PCs Drive HP Q3 2017 Results

E-mail Print PDF

HP beats Wall Street expectations as it reports Q3 2017 revenues of $13.1 billion, a 10% Y-o-Y increase. However profits are down, slipping from $783 million in Q3 2016 to $696m.

HP WorkstationThat said, the company remains bullish about the results, particularly since the Personal Systems business sees "incredible" 12% Y-o-Y growth, bringing in revenues of $8.4bn. Commercial revenues are up by 11%, while consumer revenues increase by 14%. In addition, the company reports total shipments are up by 7%, driven by a 12% increase in notebook shipments.

Desktop and workstation shipments are down by -3% Y-o-Y.

Successful Real World Test for 4D Quantum Encryption

Researchers at the University of Ottawa manage to send a message with high-dimensional quantum encryption between two building rooftops, marking a first successful test for the transmission of such signals.

Quantum transmissionQuantum encryption uses photons to encode information as quantum buts. The simplest form of quantum encryption is 2D, where each photon encodes one bit (either 1 or 0), but a photon can encode even more information, making "high-dimensional quantum encryption." The scheme used by the University of Ottawa is referred to as "4D," because each photon encodes 2 bits of information. This provides 4 possibilities, namely 01, 10, 11 and 00.

High-dimensional quantum encryption sends more information per photon. It is also more tolerant to signal-obscuring noise (such as turbulent air, failed electronics and detectors) before the transmission becomes unsecure. The real world test involved optical setups set on two rooftops 0.3km apart, and had the messages showing an error rate of 11%, below the 19% threshold required to maintain a secure connection.

Google Details Titan Cloud Security

How does Google take care of security in its cloud servers? A company blog post reveals the details-- Titan, a "secure, low-power microcontroller designed with Google hardware security requirements and scenarios in mind."

Google TitanAs the blog post explains, the Titan chip integrates with the secure boot process. This involves the server boot a known firmware/software stack, cryptographically verify the stack and then gain (or fail to gain) access to network resources according to the verification. Titan also adds further layers of security, namely remediation (reestablishes trust in the event of firmware bugs) and first-instruction integrity (identifies the earliest code running on each machine's startup cycle).

For the curious about the hardware, Titan consists of a secure application processor, a cryptographic co-processor, a hardware random number generator, a sophisticated key hierarchy, embedded static RAM (SRAM), embedded flash and a read-only memory block. It communicates with the main CPU via Serial Peripheral Interface (SPI) bus, and interposes between the boot firmware flash of the first privileged component (such as BMC or PCH) to observe every byte of boot firmware.

Intel Unveils 8th Generation Core Chips

The solar eclipse taking place over N. America brings about the launch of the 8th generation Intel Core chips, starting with mobile processors promising a 40% performance boost over the previous generation.

Intel chip Designed for notebooks and hybrid devices, the "U-series" consists of 4 processors featuring a thermal design power (TDP) of 15W. Intel says the new Core i5 and i7 processors can lead to notebooks and tablets with up to 10 hours of battery life, as well as the aforementioned performance boost.

All the revealed processors are quad-core, with support for 8 threads and updated UHD 620 graphics. This makes them more suited for games, 4K video playback, VR and video editing. The Core i7-8650U and i7-8550U have 1.9 and 1.8GHz base clock speeds respectively (up to 4.2 and 4.0GHz in boost mode) and also include 8mb of L3 cache.

WD Offers 20TB Storage With My Book Duo

Western Digital launches what it says is its highest-capacity storage system yet-- the My Book Duo, a desktop RAID system featuring capacity reaching up to 20TB.

My book DuoThe My Book Duo connects to PCs via USB 3.1, and provides performance reaching up to 360MB/s sequential read via USB-C port. For compatibility with older machines and connection of additional accessories (including drones, action cameras, card readers, keyboards, mice, USB drives or phones) it also features with two USB 3.0 Type-A ports.

WD adds the firmware is RAID-optimised, making it "perfect" for two-disk array systems with drive operation auto management, helping ensure read/write cycle data integrity. Security is also included in the shape of password protection and 256-bit AES hardware encryption with built-in WD Security software.
