I was trying to compare overall system performance, not raw cpu capacity. Also, I'm trying to compare moderately priced components. I'm lumping all the contemporary parts of a typical Skylake system to what was contemporary several years ago in the same ballpark price range. The benefits of the new high end Skylake stuff is dubious. In any case IMHO, compared to what I've been using, Skylake is awesome. FWIW, see my post below for details of what I was trying to talk about.
I bet like me he's talking overall system performance. The bulk of his improvement is probably DDR4 memory, SSD storage and maybe some CPU probably attributable to a larger L3 cache. The other Skylake benefits of integrated graphics and low power probably are likely less important to a Scala developer.
I agree. I was comparing overall system performance, not raw cpu capacity. Sorry if I was misleading - it wasn't intentional. See my post below for the details from my quick tests.
Sorry if I implied that the CPU itself is 3X faster - by across the board I meant I meant the whole computer PassMark rating as reported by PerformanceTest 8.0 from CPUComparison.com for an i5 system (3210) and an i7 system (994).
I'm comparing three computers, the HP RP3000 POS system we used to sell, the Desktop I use daily and a new i5 computer we are considering to use instead of the RP3000.
The RP3000 uses an Atom Processor and its associated Intel chipset video and 4GB PC2-6400 ram and WD 500GB Caviar Blue HD
My desktop is a Core i7-920 2.67Ghz on an Asus Sabertooth X58 with an NVidia GT610 graphics card with 24GB PC3-12800 ram and WD 1TB Caviar Black HD
The new Skylake system is a Core i5-6500 on an Asus Z170M-Plus with 8GB PC4-19200 ram and Samsung EVO 128GB SSD
Here are the rating details:
PassMark RP3000 - 260, CPUMark 249, 2d/3d GraphicsMark 63/NA, MemoryMark 242, DiskMark 332
PassMark i7-920 system - 994, CPUMark 4916, 2d/3d GraphicsMark 435/158, MemoryMark 1436, DiskMark 664
Passmark i5-6500 system - 3210, CPUMark 7366, 2d/3d GraphicsMark 622/1092, MemoryMark 2713, DiskMark 4373
Conclusions:
The i7 processor and GT 610 video card on my desktop computer was not the highest performance model 2.5 years ago but the model that fit my budget at the time. I went back and checked the costs and I exaggerated that- it was 2x the cost of my i7 system and not 4x the cost.
The new Skylake CPU and Z170 chipset is much cheaper and faster than systems from several years ago.
For about the same money, the i5 system is more than 10x faster than the HP system most of our customers have for about the same cost.
Finally, the power utilization is shockingly low. According to CPUID HWMonitor, the power of the whole system is usually under 5 watts in the i5 system versus over 100 watts on the i7 system. Using BurnInTest Pro, I could not get the i5 system to draw more than 38 watts.
While its clear that Moore's law in the CPU category is in trouble, the overall system performance with the integrated graphics, DDR4 memory and SSD storage has made up for it. As an added bonus all this is been made available with low power capability suitable for tablet/laptop systems.
We're testing Skylake processors and Z170 chipset motherboards for moderately priced POS systems. The Core i5-6500 based system is 3X the performance across the board of an i7 based system from 2.5 years ago at 1/4th the cost. The relatively low cost, low power (read quiet operation), and performance are amazing. Putting these into a surface pro has got to be really awesome.
That's an interesting question. We have a Model S P85 which is the high performance version from a couple of years ago. It does not have dual motors or ludicrous mode. When we first got the car, we did do a bunch of maximum acceleration because its such a novelty, but since then it rare that we floor it. Flooring a high performance Tesla is like being in an amusement park. Its a lot of fun - but if you really do it all the time you are a dangerous reckless driver. The model we have accelerates faster than the '02 Z06 Corvette I sold last year and my motorcycle. The new ones are *way* faster than the Tesla we have.
That said my wife was able to (barely) avoid a t-bone accident by stepping on it. That one incident alone convinced me of the value of high acceleration to avoid an accident.
It would be interesting if Consumer Reports would provide a lot more detail about reliability by model instead of a blanket statement that I suspect may not be accurate and is so contrary to our experience.
We've had our Model S for almost two years. The only issue we've had was with the tire pressure sensor. It would say we had low pressure when we didn't. Tesla came out to where our car was parked and replaced a wifi antenna. Who knew tire pressure sensors use wifi? In any case once they replaced the wifi antenna with a newer design that problem went away (except for when we got a nail in the tire). The limited experience with Tesla service has been amazing.
Other than that - 0 problems. No noises, rattles or squeeks. No charging problems. No drivetrain problems. It just works. We paid a couple thousand extra to extend the warranty from 4 to 8 years, so if my knocking on wood right now doesn't work, at least I won't have to pay for a long time. The warranty covers everything except tires. Even windshield wipers, and brakes are covered.
There may be 100,000 reasons not to buy a Tesla, but from our experience, reliability and maintenance is not one of them.
We've had ours for almost two years in Chicago and we did have a couple of bad ice storms. The handles popped out ok. I guess the motors are strong enough to break the ice...
SMT is a challenge for DIY regardless of what technique you use, especially if your eyesight is not excellent and your hands are not very steady. I use SMT to through hole adaptors.
...to unnecessary regulation codified by politicians who don't understand the technology in question. At the end of the day, it only drives up cost and stifles innovation. At most we need to enforce a law that says you cannot operate something without the owner's permission except in cases of public emergency.
I actually agree. I own a Tesla but not stock. I just don't think that Tesla is insignificant and I do think that they have had a substantial impact on the market by demonstrating the feasibility and desirability of an electric car.
For what ts worth, speculative investors don't agree that Tesla is insignificant. Tesla's Market Cap is in the neighborhood of $33.8 billion whereas GM is $47.5 billion.
From my view, they are already important. Many automakers have either introduced or announced electric cars in response to the positive public perception of Teslas. Tesla will be selling much more affordable cars in the next 5 years. I think electric cars powered by wind and solar will be a big part of our personal transportation future and that was unarguably ushered in by Tesla.
I can't really argue the point because I have not personally tested lunar samples or performed fusion experiments.
That said, I have read *many* articles in popular press concerning the relative abundance of lunar He3 and its benefits as a fuel. E.g. http://www.extremetech.com/ext...
I'll take your points and these articles with a grain of salt.
Actually if there is a breakthrough with fusion power generation, we'll need a lot of Helium-3 which should be plentiful on the moon.
If we are to colonize something other than earth, we need the experience of thriving in harsh environments.
The fact that we cannot detect intelligent life elsewhere in the universe implies a responsibility to spread humanity - an off-site backup if you will...
When you have a lot of space you are more likely to waste it which is a problem when you want to keep it backed up to the cloud. This is especially true for rural users with poor internet connections.
Its just an opinion. Most people I know who have read the book liked it too.
I don't really care if you don't take my opinion seriously. As such, feel free to stop reading this at this point. Hopefully others who may like the story will take your opinion with a grain of salt.
I agree that a lot of the science is not well explained, but with science fiction I always must suspend disbelief. I like Star Trek too, but c'mon - travelling through wormholes and time? Not really likely and also not the point.
It's been a while, but I thought he was asleep when the hydrogen mix went way up. He noticed immediately when he woke up.
Please explain what's wrong with the stoichiometry. Hydrazine is N2H4. React O2 and you get two H2O and one N2. I agree that getting this desired reaction safely may not be well explained.
The potatoes were genetically engineered and he had bright lights. I agree that its unlikely, but it is at least plausible.
In any case, like any book, some like it and some may not. I recommend you skip the movie - I think I'll like it.
Alternating current solves a major problem in distribution. Very high voltages to transfer energy over long distances with lower current are the way to go.
If you are producing your own energy, say with photo voltaic cells to store in batteries, AC is an unnecessary conversion step.

Actually the controls are very easy to use and the steering wheel has mechanical controls that adjust fan speed.
Was the charging free?

If all I need is one or two boards, I just wire wrap. I have no idea why so few people talk about this in the maker community.

So the expensive 11X17 epson color printer I bought 20 years ago that was basically made this way is a new advance?
When I didn't use the printer for 6 months, the print head dried up and the expensive printer was garbage.
How much are replacement print heads?
