NASA's HI-SEAS Project Results Suggests a Women-Only Mars Crew

edxwelch Re:Compelling, but a mix still better... (394 comments)

Better yet, how about sending dead people?
Dead people eat even less food than women and let's face it they're going to end up dead anyway, so this just gets it over with quickly.

If You're Connected, Apple Collects Your Data

edxwelch Re:That's absurd, aim your hate cannon elsewhere. (312 comments)

Of course, the data is not sold to thrid parties. It's used to monitor who is making negitive comments about Apple. Once Apple unleash their invincible robot army and takes over the world, these herectics will be sent to the labor camps.

The Physics of Why Cold Fusion Isn't Real

edxwelch Re:TL;DR (347 comments)

I think a better summery is "blogger creates click-bait post by sowing acute ancetodes about mechanical turk, etc. and a few technical looking graphs together to form a article that appears interesting, but really is just a bunch of waffle."

Android On Intel x86 Tablet Performance Explored: Things Are Improving

edxwelch Re:When an x86 Android Phone in the US (97 comments)

The reason why is because Intel's modems haven't been certified yet for American operators.

Lockheed Claims Breakthrough On Fusion Energy Project

edxwelch Re:More nuclear waste? (565 comments)

No, I'm talking about fusion. The neutrons need to be slowed down for effective tritium breeding and that's done by a modifier (usually graphite)

Lockheed Claims Breakthrough On Fusion Energy Project

edxwelch Re:More nuclear waste? (565 comments)

That's interesting, but the devil is in the details.
A fusion rector needs a neutron multiplier and a neutron moderator, as well as the lithium breeding material. Even if the container material is somehow shielded, the moderator and multiplier materials will absorb neutrons becoming radioactive.

Lockheed Claims Breakthrough On Fusion Energy Project

edxwelch Re:More nuclear waste? (565 comments)

Except you forget about the high energy neutrons. They are absorbed by the reactor walls, causing the containment vessel to become radioactive and require frequent replacement.

NVIDIA Launches Maxwell-Based GeForce GTX 980 and GeForce GTX 970 GPUs

edxwelch Re:Still 28nm (125 comments)

I doubt that.
TSMC 20nm will be ready for GPUs a lot sooner than their 16nm process. The only reason there are no 20nm GPUs yet is because the initial ramp was fully booked out by Apple.
Meanwhile, a comparison of Apple's 20nm A8 density versus 14nm Core M, indicates Intel's 14nm may not have such a density advantage as they claim: https://www.semiwiki.com/forum...

Why the iPhone 6 Has the Same Base Memory As the iPhone 5

The explaination is quite simple: more beer!
If you buy the 16GB instead of the 64GB you have and extra $100 left over to spend on beer!

NVIDIA Launches Maxwell-Based GeForce GTX 980 and GeForce GTX 970 GPUs

edxwelch This is bad for AMD (125 comments)

The GTX 970 is as fast as AMD's flagship R9 290X, much more power efficient and is $170 cheaper. This means AMD will have to knock down prices by a huge amount and
they are sort of depending on graphics revenue to break even, because of falling CPU marketshare.

NVIDIA Sues Qualcomm and Samsung Seeking To Ban Import of Samsung Phones

edxwelch Interesting article on Semiaccurate about this (110 comments)

Previously, Nvidia said that it would license it's Kepler GPU cores to third parties. Semiaccurate maintains that this licensing program was in fact bogus and was conceived purely to justify future patent trolling activities. Semiaccurate also claims that
Nvidia tried to "shakedown" Apple with the same patents and Apple subsequently gave the contract for the Mac Pro GPU to AMD as punishment.

Intel flops on Android compatibility

edxwelch edxwelch writes  |  about 6 months ago

edxwelch (600979) writes "Intel claim that 75% of all Android apps in the market are pure Java and don't feature any native ARM code. Using their binary translator they hope to bring compatibilty up to 90%.
However, a new report conducted by ARM disputes this. They ran a survey of the Android app market and found that only 20% of the top apps are pure Java, 30% are native x86, 42% require binary translation and 6% do not work at all on Intel's platform. To make matters worse the level of compatibility is falling. They also found that running an app in binary translation mode takes a huge performance hit."

OpenGL 4.4 already has DirectX 12 and Mantle-like features

edxwelch edxwelch writes  |  about 7 months ago

edxwelch (600979) writes "The announcement of DirectX 12 was a big focus of attention at GDC yesterday. The new API will bring Mantle-like low level access to the hardware, reducing the CPU overhead.
The OpenGL talk "Approaching Zero Driver Overhead in OpenGL", on the other hand, received considerably less media attention. The OpenGL camp maintains that the features to reduce CPU overhead are already present in the current version. They suggest using the extensions such as, multidraw indirect combined with bindless graphics and sparse textures, OpenGL can get the similiar "close to the metal" performance as Mantle and DirectX 12."

Intel engaged in below cost selling

edxwelch edxwelch writes  |  about 9 months ago

edxwelch (600979) writes "An analyst at Bernstein Research has found that Intel is selling their tablet Bay Trail chips to OEMs below cost, concluding that after end rebates, Intel’s tablet revenues are likely to be “close to zero,” while profits will be negative.
Intel has responded that the “special costs” Intel is incurring are not pushing down gross margin.
Intel needs to offer the subsidies to OEMs building $199-$299 devices to bring the bill of materials down and make them competive with cheaper chips from the likes of MediaTek and Rockchip."

It will have two Steamroller CPU cores and a GPU with 512 SPs (equivalent to Radeon HD 7750). A demo was showing Kavari running Battlefield 4 at twice speed of a Core i7 4770K with GT630."

AnTuTu benchmarks optimized to favour Intel

edxwelch edxwelch writes  |  about a year ago

edxwelch (600979) writes "A recent report by ABI research showed Intel's Clover Trail+ outperforming SoCs from Samsung, Qualcomm and Nvidia.
However, a EETimes article casts serious doubt about the validity of the report, in particular the AnTuTu benchmark used to test the chips.
"Going from the 2.9.3 version of the AnTuTu benchmark to the 3.3 version, the overall AnTuTu scores increased 122 percent, and the RAM score increased 292 percent for the Intel processor, while the scores for the Samsung processor increased only 59 percent and 53 "
To top things off, somebody analyzed the assembler code in the AnTuTu benchmark and found clear evidence that the benchmark had been tweaked to favour x86 processors."

The real reason Firefox lost to Chrome: Firefox 4

edxwelch edxwelch writes  |  more than 2 years ago

edxwelch (600979) writes "In November last year Chrome overtook Firefox in market share for the first time. What people don’t realise is that the release of Firefox 4 caused a large part of the decline.
Firefox 4 was a major new release and came with a brand new Javascript engine and HTML5 parser. Unfortunately, these new features came with major memory leaks and performance bugs. The result was that if you used Firefox 4 for an extended period of time the browser would eventually become unresponsive, making it virtually unusable."
