I've been using since it was a German Company called Astaro. Good stuff.
By far the best solution I've come across. It's a enterprise class product you can use at home for free. All you need is a PC with a couple NICs. I use a cheap fanless Dual Core 2GHZ Atom machine with a couple gig of RAM. It's a turn key solution with a lot of options.
It has all the whiz bang VPN and firewall features you'd want. Plus a bunch of intrusion detection, malware and virus features. Really the list feature list is huge. The only limit is the home edition is limited to 50 active devices.
Indeed. It helps that R is the learning language many stats programs use in college these days. Often the college kids no more than the experienced Matlab/SAS folks. It also helps that many "big data" databases will natively run R code. HP Vertica in fact will split and optimize R between all the nodes in the cluster.
R is definitely a language on the rise for big data applications.
American, Delta and United are the top three airlines in the US. Seat maps and seat assignments can change several times between time of purchase and flight. That's because routing can change every time there are Irregular Operations (IROPS) and the fleet movement changes to deal with it. I.e. Weather, Mechanical issues, etc.
None of the top three airlines have homogenous configurations. American is a mix of US Airways and American, United is a mix of Continental and United and Delta is a Mix of Northwest, TWA, and a slew of secondary market planes from Airtran, various Red Chinese carriers and European carriers and Delta.
Southwest only has 737s and coach class, but they have 5 different versions of that plane with drastically different capacities.
That's great, and I use these sites all the time. BUT, the majority of flyers are casual leisure passengers. They are unlikely to figure out which of the dozen 757 configurations Delta offers they are flying on. They just don't fly often enough. I think the model would be turned on it's head if minimum seat pitch was a required to be shown when presenting prices.
They go farther than Apple in a number of areas. The primary one is Apple's dev tools are free. Microsoft's developer tool set ranges from $600 to over $13,000 per seat.
To clarify, when I say run I'm talking about as HTML/CSS/JS, not using the Java web plugin.
I think that's a pretty dated view of Java. If I'm writing a web service endpoint most of the heavy lifting happens with some very simple method/class @Annotations. My controller classes tend to be in the tens of lines, not hundreds of lines.
The days of writing a some inordinately overthought out factory pattern are long gone for a lot of stuff and the JVM does all sorts of optimizations to make the performance gap between VM and Native pretty small.
There almost needs to be two separate considerations. From a language standpoint Java is a bit middle of the road. It has some well known pain factors, but more or less it's one of the easier OO languages to master. It's used in a lot of high profile web site.
The VM on the other hand does a lot of interesting things under the covers that make the language quite fast. When JRuby hit the scene it was faster than the core ruby project at quite a few things because the VM was doing all sorts of optimizations behind the scenes. Also, because the Java OP code is so stable with relatively few changes per major release you have a bit of a boom in languages you can run inside the Java VM. You get all the benefits of the R&D Sun and Oracle put into JIT, while retaining the ability to do interesting and contemporary things with your language.
Clojure, Groovy, Scala, Python being the primary languages with another 16 that can compile to Java Op code.
Were Java fails mostly is as a client application, running with some sort of Windows GUI. Sure, you can do it, but it realistically people who do Java Swing apps are writing some sort of thick client that could almost always could run inside a contemporary browser without any plugins.
That's pretty much what happened to the colosseum. Stone and marble was torn out. A chunk of it ended to make the vatican.
The US has way more generation facilities that it really needs. The issue is entirely political with the 500 or so companies that make of the "grid". You're unlikely to see a solution to that because it would put a number of facilities out of business.
I'd also point out that Germany's accelerated decommissioning of nuclear power plants (all shutdown in 8 years) has a lot more to do with the coal plants than the increase in renewables.
To be fair the two largest HVAC providers in the US already offer predictive modeling services for regulating power consumption. Many times having complex interactions with market based supply/demand power pricing that's common in the commercial applications and buildings. We have models and systems already in the market place that take into account a number of these issues.
Currently in the HVAC arena all the predictive models are predicated on still storing the energy in the form of chilled water. The systems figure out demand for the next day and determine the optimal time at night to chill down thousands of gallons of water based on the market (or predicted market) off peak power prices.
Be that as it may we have off peak facilities for a reason. As you pointed out getting the grid to handle this would be no easy task. The grid is made of 500 or so different companies, most of which are only obligated to serve in the interest of the community it serves. As such we have way more generation capability than we have transmission capability. Good luck getting a majority of the companies to agree. Previous attempts by the feds to use it's power (2005 during the Bush administration) was thwarted by congress. So, I guess my main point is it's not a technology issue, we already do a lot of the stuff he's proposing in the off-peak market. What we have a political problem with transmission.
One of the problems with the historical sites in Greece is so many of the large ones have been stolen from over the centuries. Want to see the full Parthenon? Better book a trip to the Vatican, Louvre in Paris and the British Museum what's still left for public viewing. Various conquers and rulers have been selling off bits and pieces of greek history for as long as Europeans have been collecting art.
We're seeing more and more solar units down as leases. Many companies specialize in the financing behind it and it includes management and maintenance. What does this mean to renters? If solar were to become economical it's not inconceivable that the renters would buy electricity from the management company and give the landlord a cut.
If it was a review copy most likely it contains a uniquie hidden watermark. There are several firms in Hollywood that specialize in pressing watermarked screening DVDs. I would guess they would have already been questioned.
