More than half the people here are opposed to this because it's vaguely associated with the military. Get a grip. The military ties are a hook to get funding, since defense is the sacred cow of the federal budget. Better money spent on this than turkeys like the F-35. Technology like this is so general and widely applicable that it's useful no matter what excuse is used for development.

Exaflop computing isn't that widely applicable, except to highly parallel algorithms, and we more or less have that covered by adding bunches of PCs together, rather than actually building faster computers capable of solving linearly dependent problems, which are the new interesting problems.

Frankly, I think this guy is a little more interested in keeping people who want to build exaflop computers employed than he is in actually solving problems (surprise: he happens to be a member of the group that would be employed by this type of funding). I also think that IBM is feeling a bit hurt because of the recent supercomputer purchase contract they lost out on because they wanted too much mone for the thing (surprise: he happens to have more than a little involvement with IBM).

Why is it bad to give them real estate subsidies? Real estate taxes are not the primary revenue generator of city income.

I think you are confused. I was answering the question of "What's the appeal?"; you appear to be defending the adversary position to the position in the article. I didn't take a position on that one way or the other, so I'm a bit confused as to why you are defending this position to me.

I'm not sure you realize how important it is that NYC diversify its economy. 20% of our tax base comes from wall street. Not simply the corporate taxes, but the salaries and bonuses. When they take a hit, the city can face some very real financial trouble.

This is a different problem; this is called "spending more money than you take in". California has the same problem; in fact, very few states do not operate on a deficit in the current economy, and the ones which don't are the red states, like Texas, which are inherently fiscally conservative, and tend towards social conservatism, as well: if you don't pay for large social programs, you can save that money for a rainy day.

The goal of these tax breaks are not to attract one or two big companies, but to foster a community of startups by reducing capital requirements.

The best part is that its working. The economy in NYC has been very strong relative to the rest of the country, but recently its felt incredibly vibrant. Much of this is the product of a growing community of test startups.

I think you are rephrasing what I already stated as the goal. I think you are reply to the wrong posting.

Comment There are two axis for fragmentation. (Score 2, Interesting) 419

There are two axis for fragmentation.

The graph is showing the one that doesn't matter, since you can always target a subset of the APi which is supported by all the versions of the OS; that's the same for both iOS and Android, and it's just common sense code portability. The first product I worked on out of college was TERM software for a small company called Century Software in Salt Lake City, Utah, At one point, we had greater market penetration for async communications software on UNIX systems than UUCP, and UNIX systems came with UUCP for free. We also ran on VMS, BTOS, CP/M, MP/M, Mac OS, and half a dozen other non-UNIX platforms, as well as the 140+ UNIX platforms we ran on.

The secret to this success was to have as small a porting surface as possible, and that's eminently possible with both iOS and Android, although that type of design and coding tends to not be taught in colleges and universities these days, it's still eminently possible. It's just a matter of API contracts.

The other axis is hardware differences, and you can't ignore those for either iOS or Android. Those are the ones you can't get around with API contracts, because they touch on different device capabilities - the most important of which is screen aspect ratio, and that's the very thing that iPhone 5 broke, and it's the very thing the original iPad broke. Sure, there are other important parts to this; there the "I" in "I/O" as well, in particular, of all the sensors, there's keyboard inputs, but for the most part, that has fallen out to touch interfaces, which pretty much everyone other than Blackberry has agreed upon, and GPS. All the other sensors are much less useful to most apps.

If you talk to a Rovio engineer (and I have) on this issue, they effectively target a dozen iOS hardware platforms: to get the best user experience, and to get where they are today, with "Angry Birds" being the top selling mobile game of all time, they've had to adjust to aspect ration, resolution, and OS version. Being a game has meant having a much larger porting surface, in terms of OS interaction. And yeah, this means several dozen Android platforms, as well as their other platforms, but the difference between a dozen and several dozen isn't as large as the difference between 1 and a dozen.

Rather than pointing to Apple infographics, you'd be much better off pointing at the biggest success story in the industry, and doing as they do, rather than doing as Apple would have you do, since it's more important to be a top seller than it is to be portable, if the end goal is popularity with users and income.

Comment Intel owns Thunderbolt (Score 1) 397

Thunderbolt is Apple proprietary. The Intel version which is freely licensable is called Lightpeak.

Your facts are wrong. Intel developed this technology and the code name for it was Light Peak. Apple registered the trademark for Thunderbolt but transferred the rights to that trademark to Intel two years ago. Thunderbolt is not proprietary to Apple in any meaningful way.

Hardly anything supports it.

Thunderbolt is just PCI Express and Displayport with DC power baked in. Both PCIe and DP are well supported and widespread. A Thunderbolt port can be used for PCIe or Displayport devices. It's accurate however that Thunderbolt is not widely used outside of Apple products at this time.

Comment Intel developed Thunderbolt, not Apple (Score 1) 397

No, Lightpeak is Intel, Thunderbolt is Apple

Light Peak was the code name for Thunderbolt which was developed by Intel and Intel owns the full rights to the trademark. It uses an Apple developed connector and Apple was the first ones to put Thunderbolt on their machines but it is unambiguously an Intel owned technology.

Intel developed Lightpeak, Apple simply purchased the technology and named it Thunderbolt, hence Apple owns the trademark on that one.

Apple transferred the Thunderbolt trademark to Intel about two years ago.

If you want to use IEEE1394, you need to pay... Apple.

As well as 9 other corporations that hold essential patent rights to the technology in IEEE1394.

Waiting for the inevitable mod-down by Apple fanboys who dont like the truth.

Since virtually all your facts are wrong you might consider taking a less adversarial tone.

This is because you allowed your elected officials to let gasoline become a traded commodity. if you were do demand they not allow it, price stability would return.

"Pretty much all your luxury cars should be running that, and many regular cars."

Ahh yet another uneducated car owner.... Unless the car is turbocharged, supercharged, or high compression you are a moron to run anything but the low grade "regular unleaded" gas

Higher octane burns SLOWER to reduce knock. this is used for Forced induction engines and high compression engines. Both of which are RARE to find in cars. less than 40% of all cars sold meet this need.

Sadly many uneducated drivers fall for the marketing of "premium" gas being better or having more additives.. They don't. It's just marketing to get people that don't know any better to buy the overpriced fuel they do not need.

What's the appeal? -- you need to RTFA

You need to read the fine article. The locations in Brooklyn are subsidized, both through actual rent subsidy, and temporary tax exemptions being extended to tech companies: NYC wants these businesses moving in, and they want it in a rather large way, since they don't see bodegas, taxi companies, or a lot of other non-tech businesses as being a growth industry for increasing the tax base.

Without a huge investment in a redevelopment effort to knock down buildings and grow things up, about the only thing they can do is try to increase tax revenue by incentivizing higher income businesses to locate in the area -- and right now, that means tech companies.

The article specifically complains about these types of companies being preferentially subsidized.

About the only things worse that NYC could be doing to itself right now, besides reducing the caffeine intake for software engineers by limiting cup sizes, I mean, would be to be extending these subsidies to the Wall Street folks instead, or passing something like California's Prop 13, and having it apply to non-residential, non-parking structure commercial properties, as it does in California right now (thank you, Kaiser Family Trust -- NOT). There's a reason that San Francisco has built up huge numbers of un-rented high value per square foot commercial properties, and is knocking down older buildings an parking structures everywhere they think they can get away with it.

A battery pack swap will cost between $60 and $80, about the same as filling up a 15-gallon gas tank,

It costs $47.25 to fill up a 15 gallon tank here. However this isn't California, thank God.

Actually, it's $52.35 in California, if you go to one of several Bay Arco stations not in San Francisco or Los Angeles. So even in California, it's between ~$8.00 and $28.00 higher than filling up a 15 gallon gas tank. So swapping out the battery pack can be up to 150% the cost, if it comes in at the high end of things. I guess electric vehicles are only cheaper to operate if you build some more nuclear plants to make cheaper electricity.

Blurry image?

Yes, blurry image when compared with LCDs. All CRTs have a (slightly) fuzzy image. Calibration helps (though it is almost never done in practice) and it can be minimized to the point you probably won't notice but CRTs do not produce as sharp an image as an LCD.

Power usage? Sorry, but the massive Sun CRT I mentioned did around 100 Watt, which is just as much as a professional level (like the Sun) LCD uses, like those from Eizo.

LCDs consume 50-70% less energy when in use than CRTs of a similar size. The precise amount varies but any argument that CRTs are competitive on power consumption is easily refuted in almost all cases. I'm sure you can probably find a corner case where some CRTs are competitive with specific LCDs but such examples would be rare at best.

Flicker is utter nonsense. It's true that below their recommended refresh rate the phosphor pixels will fade faster than they are refreshed, leading to an uncomfortable experience. Even at 75 Hz I never had any issues, nor 60 Hz for older (15") CRTs.

Right. Millions of people have just hallucinated that CRTs flicker. [/sarcasm] Seriously, don't even start with this one. CRTs flicker and most were never set at sufficiently high refresh rates. A CRT at 75Hz is usually bearable but the flicker is still observable to many and uncomfortable for some. Personally I can still see flicker in some conditions even at 85Hz though it no longer is uncomfortable for me at that refresh rate. I can't remember the last time I used a PC that the person using it had set the refresh rate higher than 75Hz and most seemed to leave it at 60Hz which would drive me crazy.

CRTs are now a niche product. For most applications they are inferior to other available display technologies. They have their advantages but their disadvantages are legion. I don't miss using them even a little bit.
