Mac OS X Power Consumption vs. Ubuntu 11.04, Windows 7

Filed under
OS

Last week we delivered results looking at the power consumption of Ubuntu 11.04 versus Windows 7, which was interesting in its own right, but in this article is a brief look at where Apple's Mac OS X operating system fits in between the power consumption of Ubuntu Linux and Microsoft Windows.

Due to hardware availability, this Independence Day benchmarking was just carried out on an Apple Mac Mini with a 2GHz Intel Core 2 Duo P7350 processor, Apple Mac-F22C86C8 motherboard with NVIDIA MCP79 chipset, NVIDIA GeForce 9400 graphics, 1GB of system memory, and 120GB Fujitsu MHZ2120B SATA HDD.

Apple Mac OS X 10.6.8, Microsoft Windows 7 Professional SP1, and Ubuntu 11.04 were all tested in their 64-bit editions and benchmarked in their stock configurations. The only change to Windows and Ubuntu Linux was installing the proprietary NVIDIA graphics driver.

OnePlus 5T review: Come for the value, not the excitement

OnePlus isn't interested in holding back on specs, features or capabilities to make a big reveal of a new phone just once a year. The scrappy company has settled in on a refresh cycle every six months, with a big release followed by a mid-cycle bump to bring in the latest things it's been working on. The OnePlus 5T isn't meant to be an innovative leap of technology that blows your socks off — and honestly, none of its predecessors have been particularly groundbreaking, either. Nope, the 5T is still about value, simplicity and being tuned for what the Android enthusiast crowd craves from its phones. At $479 there wasn't much about the OnePlus 5 you could find a flaw with. Now six months later with a bigger screen, new secondary camera, neat Face Unlock feature and a $20 price bump, it's a pretty easy equation to figure out. Read more

OnePlus 5T review—An outstanding combination of specs, design, and price

After launching the OnePlus 5 earlier this year, OnePlus is back with an end-of-year upgrade for the device. The OnePlus 5T takes a winning formula—high-end specs with a low price tag and a metal body—and reworks the front of the phone to dedicate as much space as possible to the screen. This device has a new screen, a new button layout, a new fingerprint reader, and a new camera setup. It almost feels like a totally new device. We liked the OnePlus 5 from earlier in the year, but, with the more modern design, OnePlus has fixed OnePlus 5's biggest downside. The result is something that is extremely compelling—a $500 phone that makes you question exactly why you'd give $800 to those other OEMs when this has nearly everything the more expensive phones have.

Linus Torvalds: 'I don't trust security people to do sane things'

Linus Torvalds has offered his thoughts on Linux security approaches, branding some security professionals as "f*cking morons" for focusing on process-killing rather than debugging. Torvalds, the creator and principal developer of the Linux kernel, does not often pull his punches when it comes to the kernel's behaviors and security. The engineer carried on the tradition over the weekend, as Google Pixel developer Kees Cook submitted a pull request for hardened usercopy changes for v4.15-rc1, which according to Cook, narrows areas of memory "that can be copied to/from userspace in the face of usercopy bugs by adding explicit whitelisting for slab cache regions."
