$299 Android Gaming Tablet Reviewed

default luser There's more to it than just that (65 comments)

You have to want a better streaming experience than Valve's Steam already offers for free (and you can buy a Windows Tablet for the same price, and Valve is expected to support Android and iOS soon). You can use whatever system and whatever video card you want to stream the game to and from - even go wired ethernet to get around the inevitable problems you get streaming games over wireless.

If you go Shield, the tablet price is just the beginning: you have to have a mid-range GeForce card purchased in at least the last 2 years ($120+ if you don't already have one), the controller + stand ($100), and of course a suitable dual-band router runs at least $70 (most people use the crap one that came with their internet install).

In all, you could be on the hook for anywhere from $400 all the way up to $600. That's getting DANGEROUSLY close to the same price as an entry-level gaming PC, so again the need just doesn't present itself there.

NVIDIA Launches Tegra K1-Based SHIELD Tablet, Wireless Controller

default luser Re:I can already do this on Android... (42 comments)

You'll notice in the second half if my post that I called the separate controller + tablet + stand gaming method CLUMSY, and praised the original Shield for including all-in-one. This is because I also agree with you that this sort of gaming is untenable, and I actually gave up and bought a 3DS about 6 months back to get my portable gaming fix.

Touchscreens suck for gaming!

Also, you'll notice I suggested the WIRED 360 controller because it's not nearly as complicated as pairing a wireless bluetooth controller. Just plug it in, and play your games...or you can sit here all day and complain about Android breaking your favorite bluetooth controller.

NVIDIA Launches Tegra K1-Based SHIELD Tablet, Wireless Controller

default luser Re:I can already do this on Android... (42 comments)

The K1 has *vastly more GPU power* than any other ARM SoC out.

And your point is?

Games are being produced for the mainstream to high-end currently out there, so a SoC with twice the power brings nothing useful to the table. And streaming PC games requires none-of-the-above GPU power, so it's one of those questionable value cases.

Then there's also the concern about whether K1 will throttle under load, since this tablet doesn't have a fan like last year's Shield did. You'll notice that NONE of today's reviews go into that level of detail, and that's probably no accident.

NVIDIA Launches Tegra K1-Based SHIELD Tablet, Wireless Controller

default luser I can already do this on Android... (42 comments)

With something as simple as a USB OTG adapter and a wired Xbox controller.

Believe it or not, most modern Android games already support the Xbox controller, and if you're gaming on such a tiny screen you can believe me that the wireless controller is NOT a necessity (will be 1-2 feet away at most). You can buy a $200-ish entry-level Android tablet that can handle games just fine, and reuse the Xbox controller you undoubtedly already have. So, why would you spend $300 + $100 for the same thing with an Nvidia label on it?

I'm actually disappointed that they didn't stick with the concept of the original Shield, and deliver another handheld gaming system; that alone is the only thing you cannot find in the Android world. If they insist that you use a clumsy tablet setup involving a screen prop and a separate controller, then why do we have to buy the tablet, screen prop and controller FROM THEM?

Coming Soon(ish) From LG: Transparent, Rollup Display

default luser Promises... (64 comments)

Also, there's the unavoidable problem you have with display clarity. Right now screens are on a flat substrate, and so each pixel is aligned with the next one, which reproduces an image accurately. But what happens when you have an unrolled display sitting on your desk, or held in your hand? It will inevitably be have varying levels of curve along it's length and possibly more complex crumples, resulting in poor image accuracy. Fixing that will require some clever sensors embedded in the display along with some expensive signal processing, and that fix will STILL cost you resolution.

Then when you consider that LG's current flexible displays have poor color rendition and contrast, along with piss-poor resolution, you realize how much of a lost cause this is. I cannot see myself giving up the best qualities of modern displays so that they break a little less often, and can fit in a smaller pocket.

Researchers Unveil Experimental 36-Core Chip

default luser Re:Moore's Law (143 comments)

In your glass tower, yes.

In the real world, not so much.

Here is an example of one of the world's most optimized pieces of software: x264. It's also one of the few real-world loads that can take advantage of multiple processor and SSE. So how much speedup did this incredible piece of software see with AVX2, which DOUBLED the width of the integer pipelines?

FIVE PERCENT! Yup, that's it!

All that work for so very little improvement, because in the REAL WORLD data does not align on perfect AVX2 boundaries, and data fetch is as much of a hindrance as the actual processing of that data. Read more about WHY this is the best that could be done here, if you don't mind paying for SCRIBD.

Parading around test results form something like Passmark is just self-delusion. It only tests that the features do in-fact work, and these tests tend to work directly from cache in small data sets that are usually not branch-heavy. IT gives score for number of MIPS, but does not take into account the fact that most real software can't actually make use of these features at-speed.

And when they increase the vector size yet-again to 512-bits wide in a year, it will once-again be a limited real-world improvement, because optimization of real loads is hard, and auto-vectorization of arbitrary loads is even harder problem to solve. So Intel keeps adding new features, and they keep adding about 5-7% each (real world). So I don't see how you get above 3x from those puny performance increases, while not deluding yourself.

Researchers Unveil Experimental 36-Core Chip

default luser Re:Moore's Law (143 comments)

Which uses Passmark, which is a simple corner-case number-crunching bonanza. Pure AVX2, or FMA without any real-world qualifiers, restriction or branching? Sure, we got that!

And even with that, you're still off. The performance improvement with Haswell per-core is less than 5x. See here:

http://www.cpubenchmark.net/compare.php?cmp[]=2020&cmp[]=1127

So, in the unoptimized case the performance improvement is 2-3x, and in the embarrassingly-parallel case the speedup is 4-5x. But then, if you had such an embarrassingly-parallel case, you'd just port it to OpenCL and be done with it. Haswell is for all those hard-to-optimize compute cases.

Researchers Unveil Experimental 36-Core Chip

default luser Re:Moore's Law (143 comments)

Absolutely not true.

The Core 2 Duo is approximately 2x faster clock-for-clock versus the Pentium 4, and the current Haswell core is barely 40% faster than that (assume a 7% speedup per-clock for every core rev since). That gets you somewhere in the 2x-3x performance improvement range for Haswell, barring corner-cases that are embarrassingly easy to leverage AVX/FMA (most real-world use cases show small improvements).

Intel proved that they could do a whole lot better than the Pentium 4, but your performance improvement factor is off by half!

Will 7nm and 5nm CPU Process Tech Really Happen?

Will 7nm and 5nm CPU Process Tech Really Happen?

default luser This affects our entire industry (142 comments)

Because whatever you do in the computing world, you are affected by processing power and cost. Growth in these regions drives both new hardware and new software to go with it, and any hit to growth will mean loss of jobs.

Software (what most of us here create) usually gets created for one of two reasons:

1. Software is created because nobody is filling a need. Companies may build their own version if they want to compete, or a company may contract a customized version if they can see increased efficiency or just have a process they want to stick to. There used to be a lot of unfulfilled need out there, but this demand is much sated in the 21st century.

2. Software is created because a company desires increased performance/new features (basic need is filled, this is a WANT). Once a new processor/feature becomes available, you either wedge it into existing code. Or, if it's a massive enough of an improvement, you create entirely new software enabled by the new level of performance-per-dollar.

Without continued growth, the industry is in danger of cratering because there's only so much processor architecture optimization you can do in the same process node, and the same goes for optimized libraries on the software side. In addition, brand-new industries enabled by cost reductions (e.g. digital FMV explosion in the 1990s, or the movement to track your every move in the 2000s) will no-longer be so common, and that will again force people to look elsewhere for employment.

Software engineers won't disappear, but they will be culled. The industry has not had to deal with that yet in it's entire history, so it will be painful. I'm hoping they can hod this off for as long as possible!

Kingston and PNY Caught Bait-and-Switching Cheaper Components After Good Reviews

default luser Re:Kingston selling shit USB3 flash keys (289 comments)

You compared A 128GB drive to an 8GB drive. That's likely your problem.

Flash is inherently parallel, which means that the more chips you have, the more bandwidth the controller can extract. USB 3 versus USB 2 is of no concern if you can't even squeeze enough bandwidth from the flash chips to saturate the interface.

There is also the quality of the controller that could affect things. USB 3 flash controllers come in all sorts of different specifications: you can have something that barely exceeds the speeds of USB 2, or a slightly more expensive controller that has fast block reads but poor small file performance and slow writes, or you can pay a premium price for all-around excellent performance. This is the same thing you saw in USB 2 land, and also quite clearly seen in the SATA SSD world, so why would you expect anything less in USB 3 land? You bought a bunch of low-end "USB 3" labeled parts, and you probably got exactly what you paid for.

This happens in every industry, because there's a different set of requirements for every purchase, and an OEM ticking all the right boxes at the right price gets the sale, so they make sure to have lots of different options. Don't blame Kingston because you were shopping for crap and received crap.

This is not the same as relabeling products with advertised speeds that are higher than what was delivered. THAT is bait-and-switch, which is reprehensible. That has nothing at all to do with your case, which was simply a case of you not doing your homework.

Could High Bay-Area Prices Make Sacramento the Next Big Startup Hub?

default luser You forgot a third, but very important negative re (190 comments)

3. The cities are islands in a sea of rural nothingness. Seriously, if you make your home in (e.g.) Austin, just try to commute somewhere else. San Antonio is a stretch (1.5-3 hours each way, depending on which sides of the city you are commuting to), and Houston and Dallas are out. Every other town is too small and too isolated to attract tech industry jobs.

This means that when a major tech industry in your chosen metro area craters, it takes YEARS for the economy to recover, and there's no other option available except for you to move. So if you move to the area seeking fame and fortune, remember to keep a deep nest egg, and don't expect to put down any deep roots.

Believe me, my family moved to Austin to follow the growing tech industry in 1983, and they ditched the place in the late 90s because they were tired of dealing with the boom-bust cycle. Since they moved, Austin crashed yet-again (Dell + Dot Com Bubble at the same time). The place has finally recovered and looks attractive again, but it will only be a short matter of time before another crash hits. So keep your nest egg close, and your roots shallow folks!

AMD Beema and Mullins Low Power 2014 APUs Tested, Faster Than Bay Trail

default luser Not Optimizaton Issues (66 comments)

There is a huge gulf between the quality of PC games and tablet games due to the massive performance/storage differences, even in the realm of integrated graphics.

That said, most modern PC games can be played on HD 4000 at 720p low/med settings. I know this because I play them on my HTPC with frame rates are at around the 30-50 fps mark. They play even better on AMD Trinity/Richland/Kaveri.

The problem with Kabini et-al is they castrated the GPU to just 128 shaders and 8 texels per-clock, compared to 384/512 shaders and 24/32 texels/clock for the bigger boys. They also castrated performance with a single memory channel. This results in performance comparable to HD 3000 on the desktop, but Beema has even lower performance thanks to the thermal constraints. HD 3000 was entry-level 3.5 years back when it was first released, but games have moved-on since then, and that level of performance is no-longer enough.

AMD decided they did not want this part to compete with their other offerings, and that's why the memory bandwidth and GPU power are castrated. And that's the reason this product's target is unclear - it's overpowered for your average tablet game, and not beefy enough for real PC games. And again, the power consumption is a concern.

AMD Beema and Mullins Low Power 2014 APUs Tested, Faster Than Bay Trail

default luser AMD Making Something Out of Nothing (66 comments)

For an "AMAZING" product like this is supposed to be, those are some awfully curated results right there. The product is only compared with a Core i3 (outdated Ivy Bridge) when it's actually going to win the test, and there's a plethora of multi-threaded tests that nobody on earth actually uses to put AMD's quad-core in the best light. Also, there are NO BATTERY LIFE TESTS to speak of, just "trust us" quoted TDP figures, and no pricing information.

And while it is MUCH faster at games than Bay Trail, it's not fast enough to play ANY modern games, even on the lowest setting possible. This leaves it firmly parked somewhere between tablet and ultraportable processing capabilities, so there's the question about product positioning.

Call me back when AMD is willing to let reviewers just have at it. If your product does not suck, then it does not need to be coddled.

Yahoo May Build Its Own YouTube

default luser Non-exclusive big-name videos = internet graveyard (162 comments)

I agree that you have to start at the bottom and build a community if you want to build a solid following. Big name titles mean people will stop in, and forget the place even exists once the video is done playing. I know I did that for years with anything aside from Youtube.

Not only are they aiming at the wrong end of the spectrum here , the non-exclusive video hosting means that nobody will bother linking to their copy versus the Youtube version. They're both free to watch, but Youtube has the advantage of name and platform support. Why would you make your blog or Facebook post of a video *less accessible* to your readers when Youtube is more widely available as a native app on cheaper mobile devices?

Austin Has Highest Salaries For Tech Workers, After Factoring In Cost of Living

default luser Downside: Austin is a boom/bust island in an ocean (285 comments)

It's too small a city to be widely diversified in terms of tech providers, so whenever a bubble or recession hits, the city takes a dive. There's nothing else within commuting distance with similar tech options (Dallas and Houston are too far, and San Antonio is mostly medical).

I grew up in Austin in the 80s and 90s and watched things first-hand: first there was the mid 80s (1985-86) semiconductor bust (component makers were out-competed by Japan). Fifteen years later there was the Dot Com crash (gutted Dell, as well as dozens of smaller web startups headquartered in the city). Every time the market bust, it was 2+ years before jobs reappeared, making it a dangerous place to call home.

If you want to live there, go on ahead - just make a nestegg your first priority (and take the cost of that into account when you are pricing out the city).

Free (Gratis) Version of Windows Could Be a Reality Soon

default luser Re:Kinda funny (392 comments)

Except this time there's no chance they will be prosecuted, so they're fine.

First, we're not in the same situation as the 1990s. Netscape was vulnerable because they had been lucky to have a serviceable product in the right place at the right time. But Netscape wanted to be MORE, so in a very short space of time they added Email, News, HTML Editor, Conference, and Calendar and re-branded the thing Communicator. These added bloat and instability, making them an easy target for the speedy and stable IE 5.0. Microsoft proved they had the better engineers and management and leveraged the tie-in to make the industry upend itself, and that's why they were taken to court.

Today Google has 66% of the market, and is not losing share to Bing - Bing is simply eating away at the other search engines. So Bing, even 10 years form now, is unlikely to gain more than 33% of the market, meaning a massive upending is nowhere in sight. That means Google has more to worry about from any court action.

Also, every other competitor plays the lock-in game! Google insists you use their tools/services if you want access to the Play store, Youtube and regular OS updates. Amazon locks Prime streaming to Fire devices. Microsoft and Amazon are facing an uphill battle supporting their own forks of Android because of this: they have to improve the value of their own services in any way they can.

FFmpeg's VP9 Decoder Faster Than Google's

default luser Re:Screen is the limiting factor (101 comments)

Yes, but is it significant? I thought the screen was the limiting factor, and the help file for that just says "reduce the backlight brightness".

Yes it is, if you were paying attention Intel's Haswell managed to increase "light use" battery life (spends most of the time idle) by 50% just by reducing the idle power drawn by the processor and platform.

If the processor had that much battery life impact when doing NOTHING, you can imagine it's of major importance to keep it idle as much as humanly possible.

Touch Typing

default luser default luser writes  |  about 10 years ago

What is it with the entire geek culture and touch typing? It seems these days that if you don't have at least 8 fingers on the keyboard, and a whopping speed of 60+ wpm as a minimum, you automatically do not qualify as a geek. I mean, people toss out bonus geek points if you know how to switch between QWERTY and Dvorak on the fly.

What are we, geeks, or one giant clique centered on convincing everyone else that they are worthless unless they type with one standard posture and position?

This is sickening, really. I have never learned how to type "properly." That is to say, I HAVE taken classes and even tried a couple typing tutors, but the end result has been unchanged. I still to this day type everything with two fingers.

Now, you might say, how do I get anything done with that horrible interface? You have to realize that people, even untrained, can make their bodies do exceptional things. For those of you who gaze in awe of a man who can pump out 120 wpm with his hands in perfect touch-typing position, I offer you an alternative tidbit of amazement:

I have typed this entire post to this point with my two little fingers in under 3.5 minutes.

END TEST. Three errors corrected (~99% accuracy).

Who says that there is only one "right" way to do a task?
