Comment Re: They also believe (Score 1) 129

Don't be silly. We went from cars to the moon because two of the richest and most powerful countries funneled a significant part of their money, talent, and resorces to make it happen. And had deep pockets to survive multiple failures and ability to spend zillions of dollars.

Compare this to a startup that seems to have equally grandiose ambition but a fraction of the ability and resources.

Nobody is pulling you down from trying any of these moonshot ideas. But if you want people to really believe that you have a good chance of succeeding, you need to do more than have fancy ambitions. Especially if you are asking people to i vest their money and their careers on your dreams.

That is funny and actually true for many audiophiles. The burn in myth.

But i find it interesting that no one called out ars on their shoddy experiment. If you are going to bother going through a scientific ish experiment, at least do it in a better manner.

Someone who buys a "high performance part" would be doing it on a system with other components that are well built. DACs and preamps and power amps and sources with well built power supplies, components with matching impedances, high quality speakers or headphones that offer neutral and accurate audio reproduction. Such as Sennheiser 800s or even studio monitors.

And you use well mastered and well recorded audio that has enough instruments, enough detail, enough dynamic range, enough variety - that you are testing accurately and comprehensively.

If you are going to test a high end car part for example, no matter how hokum it sounds, you will still test it on a high performance car, on a track, and driven by pro or amateur racers. In other words, enthusiasts.

You will not likely put the replacement part in a corolla and ask someone to drive it on neighborhood lanes.

Apologies for the car analogy. But i find it disingenuous that no one has sarcasm and derision when people spend stupid money on cars, parts, components, etc. And there are ricers and there are serious performance enthusiasts, and there are people who will pay a million for a vintage.

But there is a special kind of sneering that happens only with high end audio equipment. I submit that there is a lot of snake oil, as it is in many other pursuits and hobbies as well. But getting accurate audio reproduction is extrely difficult and fiddly. The component setup is extremely fragile in terms of how small inocuous component changes do make audible differences. Good or bad. And that is what some take advantage of.

You can choose where you want to draw the line.. i.e. how much of an enthusiast you want to be. But as in other pursuits, for the true enthusiast, there is often no point of diminishing return. There is only the pursuit.

So be gentle, please!

There are tons of super compact PCs available nowadays with Intel and AMD chips. They are larger than the ridiculously small Compute Stick but are still only as big as a few CD cases.

Like this AMD A6 based Zotac ZBOX for example. Fully built up with 4GB RAM, 64GB SSD, AMD HD8250 graphics - can be easily used as a dumb terminal (even as a decent standalone). Then use a remote desktop app to control your desktop. And get a wireless keyboard like Logitech K400 (or its big brother). You will still not be able to game (possibly) but you can pretty much do everything else.

Oh, you forgot $10k in annual support cost.

That's absolutely not a problem when you are running computational workloads for your business that has millions riding on it. Doesn't even have to be mission critical stuff. Even for regular analytics (never mind the "big-data" buzzword). $6k for a significant performance boost (even for specific workloads) and reconfigurability is a piddly amount.

Comment Power savings (Score 5, Interesting) 98

One has to give it to AMD. Despite their stock and sales taking a battering, they have consistently refused to let go of cutting edge innovation. If anything, their CPU team should learn something from their GPU team.

On the topic of HBM, the most exciting thing is the power saving. This would potentially shave off 10-15W from the DRAM chip and possibly more from the overall implementation itself - simply because this is a far simpler and more efficient way for the GPU to address memory.

To quote:
"Macri did say that GDDR5 consumes roughly one watt per 10 GB/s of bandwidth. That would work out to about 32W on a Radeon R9 290X. If HBM delivers on AMD's claims of more than 35 GB/s per watt, then Fiji's 512 GB/s subsystem ought to consume under 15W at peak. A rough savings of 15-17W in memory power is a fine thing, I suppose, but it's still only about five percent of a high-end graphics cards's total power budget. Then again, the power-efficiency numbers Macri provided only include the power used by the DRAMs themselves. The power savings on the GPU from the simpler PHYs and such may be considerable."

For high end desktop GPUs, this may not be much, but this provides exciting possibilities for gaming laptop GPUs, small formfactor / console formfactor gaming machines (Steam Machine.. sigh), etc. This kind of power savings combined with increased bandwidth cna be a potential game changer. You can finally have a lightweight thin gaming laptop that can still do 1080p resolution at high detail levels for modern games.

I know Razer etc already have some options, but a power efficient laptop GPU from the AMD stable will be a very compelling option for laptop designers. And really, AMD needed something like Fiji - they really have to dig themselves out of their hole.

The article says "error rate of just 4.58 percent ... Google's system scored a 95.2% and Microsoft's, a 95.06%". That means Google's and Microsoft's error rates are absolutely terrible and they really should just toss a coin!

Err no.. that was just terrible reporting. Google's attempt had an error rate of 4.82 and Microsoft, 4.94.
I guess Baidu reported it this way to make their "win" sound more sensational.
4.58 error rate vs an error rate of 4.82 or 4.94 doesn't sound that phenomenal, I guess.

Comment Re:eliminate extra sugar (Score 1) 496

I did it by eliminating extra sugar.

I cut way down on sugar, and it made absolutely zero difference on my weight. It may have other benefits, but not weight.

Then again, everybody is different. What works for your body may not work for another.

There probably is no magic bullet, other than working your sweaty ass off on a farm or building pyramids (or a machine that simulates such), which is what we are evolved to be doing. The only chubby people used to the royal families, which is like 0.00001% of the population, not enough for evolution to "care" about.

Diets are like software engineering fads: promise a Grand New Way of doing things, but in the end there is no substitute for experience, skill, patience, listening to users, and discipline. "Have you tried the new Node-Jay-Ass diet?"

I would note that the guy who dies at 65 with a Bic Mac in hand appears to be happier than the guy who dies at 82 on a treadmill sweating his bloody ass off.

I beg to differ. Unless you go to extreme levels, exercise is for building a healthy body. Diet control is for losing excess weight. While exercise certainly helps in losing weight and in boosting metabolism, it only has a marginal contribution in losing weight.

The other thing: You say you cut down sugar and it didn't make a difference. I don't know exactly what you meant, but personally, I see sugar in different forms. There's pure granulated sugar which is only a small part of our diets. The much bigger thing to eliminate is "hidden sugar" - sugar in processed foods (even canned or tetrapacked foods). There's sugar from fruits too. I remember reading about a school that replaced the coke vending machine and forced kids to drink fruit juice. Obesity actually skyrocketed. Kids were chugging half gallon fruit juice containers for lunch every day!

I am not a "paleo" person but I do believe that during our hunter gatherer days, fruits were a very seasonal treat. A few months in a year, and it was easy picking and full of nutrition and packed with energy (sugar) so all of us developed a really sweet tooth. But those fruits were only available for a couple of months a year and then, our lifestyle was drastically different too. We were energy starved, not energy overloaded.

Finally, I also see carbs as sugar. Both are broken down by the body to produce energy, and excess converted by our body into fat (energy storage for the starvation days).

So, to me, eliminating sugar means eliminating pure sugar, processed foods, fruits, and carbs. I find it difficult to imagine how doing this cannot possibly result in significant weight loss. I am fairly overweight (not obese though), and to me, following this is the best way to start the process of becoming healthy and fit again. I would rather lose 15-20 pounds and then start exercising - than doing all at once.

I feel that making this a package deal is only raising the bar much higher and giving us more chances to fail early on. If I mentally think that I have to exercise AND control my diet - chances are that after a week, due to work pressure or some other excuse, I will skip gymming. Then I give myself an excuse to start slacking off on my diet as well. Instead, I want to put myself in a position where I can succeed early on, and let that reinforce my belief system that I can "do it". I would much rather start with a simple rule of thumb - i.e. eliminate sugar from my diet.

Just my personal thoughts, please don't crucify me if I have been factually wrong on some of my notions.

Comment Re: A laptop with almost no ports?! (Score 4, Informative) 529

If you leave biases aside, and want to compare the Macbook with something else, the Dell XPS 13 would be neck to neck. I would even venture to say that the Dell is far more computer for the money (i will qualify why). Here's a comparison.

The Dell XPS 13 is extremely well built (aluminum alloy, carbon fibre - I've held it, it is gorgeous) - might possibly be a hair lower than the new Macbook (which I haven't held) but really, I think you would be splitting hairs.

The XPS 13 however has two big things going for it - it has full blown Core i3/i5/i7 (2.1 - 2.4 GHz) as opposed to Macbook's Core M (measly 1.1 GHz) - which means much better performance (i would imagine 2x-3x better), much less thermal throttling, and better graphics (HD5500 vs 5300). The other big thing is its display. XPS 13 has a near zero bezel 3200 x 1800 pixel Sharp IGZO panel that is arguably the best and most cutting edge laptop panel one can get today.

You can read a review of this panel here:

And dimensions and weight. Macbook is 11" wide and 0.52" thick, and weighs 2 pounds. The XPS 13 is a bit heavier (2.6-2.8 pounds), but is only 12" wide and 0.33"-0.6" thick. The cool thing is that because of the near zero bezels, XPS 13 is a 13" screen while only being 12" wide (typical for a 11" laptop, not for a 13" laptop).

Again, I am not saying Macbook is not good. It still seems to have Apple's obsessive attention to detail in terms of build quality and user centric design approach. But to say that it has no competion - that is no longer true. I do believe that the XPS 13 is a genuine alternative in just about every respec. The extra 0.8 may be an issue for some, but you also sacrifice a *lot* of computer for that. Then I would say, might as well get an iPad.

Saw this movie yesterday night. Absolutely loved it! I wrote another comment on this thread, but to me, this is probably how we will end up.

You should also try Neal Asher's books. They are a more extremely and futuristic version of this movie - with a lot more violence, cyberpunk style action, homicidal aliens, etc. but the underlying theme is the same. And the AIs and robots (golems) are mostly similar too. Oh, it even has AIs that have gone insane, robots that have strange idiosyncrasies, and hybrid versions of all of these.

The linked article give it a C. That's quite a bit higher than Kenneth Turan implies in his review:

Don't believe everything you read. If I had mod points I would have upvoted lkcl's earlier post.

I saw the late night show of Chappie yesterday. I am a science fiction nut (especially hard scifi and cyberpunk - Neal Asher, Peter F Hamilton, Alastair Reynolds, Stephen Baxter, etc.). Chappie is not hard scifi, nor is it grand theatric soap opera. But it paints a vision of how robots and AI would eventually get integrated into society. And I *loved* the movie for it. If you see District 9 (the director's earlier work), you will see that Neill Blomkamp has a very distinct and unique viewpoint. He focused not on technology, not on robotics and special effects, but on how all this will eventually coexist in our super fu*ked up world.

And the irony is thick in the movie. You have a bunch of outlaws - violent thugs - that first ridicule the robot/AI and try to take advantage of it, but eventually respect the being for what it is - an independent consciousness. Chappie eventually becomes part of the family. And I agree with the director's vision. The urban backdrop of modern day South Africa / JoBurg - it personifies a certain grittiness and bizarreness that just works perfectly for the story.

Sure, the movie and story has huge shortcomings. But for me, the main storyline, unique viewpoint, and the way it is directed - it all adds up to make a superb movie.

It is also worth reading Neal Asher for an even more violent and futuristic version of what this movie essentially is.

Although the friend's question was different from what you are asking, I thought that the real underlying question was the same. Hence I write.

You bring up some good points in your post. But I have to disagree on one thing. Good quality music reproduction is today more accessible than ever. There was a time when you had to get horn speakers or at least speakers as big as cabinets, class A amplification -solid state or tubes, and a really hard to setup vinyl turntable. Then there was room treatment, speaker placement, and all those shenanigans.

Not saying this is still not relevant. But today, you can get a decent pair of headphones (sennheiser, audio technical, akg, grado, fostex/MrSpeakers, etc), a decent DAC and amp (Schiit, Audio GD, etc), and good quality source and good quality digital (hi res or even redbook) - all at even a college dorm budget, and similarly compact.

I remember the days of the walkman and audio cassettes, and for sure, the progress has been dramatic. The only irony being that the single most important piece - the quality of mastering and quality of recording - has largely gone for a toss. Today, it is all about loudness wars and auto tune. But that is a different matter.

When people pursuing any hobby go beyond a certain expense level, they make purchasing decisions for most things other than money. Why is there no Slashdot argument about people paying $3 million for a vintage Ferrari or a Jag? Is there any basis to that price! Is the buyer, no matter how much an auto enthusiast, ever going to take his or her vintage Jag for a really rough spin that could risk damaging the car?

Maybe the analogy is not accurate. Fair enough. But a lot of audiophiles with really high end systems do find a difference in sound even with trivial component swaps. They will even claim that placement of certain objects in the room alters the sound.

But before dismissing them as twats, it might be worth thinking about how idiosyncratic and bizarre other people are who are equally immersed in their hobby or pursuit. The guy who is cooling his Intel CPU in liquid nitro to get the last bit of over clock - really, what practical purpose did he serve? And he probably spent a bunch of money on his rig too.

The strangest thing of all is that music is one of those strange beasts that changes quality with every trivial change in component, room, source, you name it. That is what gets audiophiles hooked. Maybe and probably it is psychoacoustics. But if you can hear the difference, it is there, right?

Now how much tweaking and money you want to throw at this pursuit, that is a very subjective thing. But dissing it and ridiculing it is also wrong. It is only one of the many things that continue to fascinate us as a species. And music is indeed very very special to most of us. We just don't pay enough attention to this sense.

I disagreed about apple being jewelry alone. Microsoft made products that people grumblingly put up with - so they could get the job done and be more productive.

Apple made products that people finally liked to use, and could use it easily enough, and fairly intuitively. When you create a great user experience like this, especially with a very low learning curve, people will adopt and use it in extraordinary ways. Once they feel good about using your products, they will feel special, like it was their private special thing. They will then become your biggest marketing team.

If anything, the industrial design aspect of Apple's products and even high price were side effects. The first was a nice to have, the second not so nice to have. But it didn't change a damn thing. It was always about the core user experience.. And how even most of the third party apps gave you the same sense of familiarity and consistency.

In a cynical way, this is like marketing a drug. You give the first few doses for free and make people realize how easy it is to use the drug and how shiny their world becomes when they use it regularly. Then step back and enjoy the fun. Apple gave people a tiny little pill yto swallow and even gave them little travel packs. Microsoft made people goto the doctor and get the drug injected up their backsides.
