You run Autocad on a netbook? You must only do 2D and must only use it to look at floorplans! I used SoildWorks 2005 and had to upgrade my video card and RAM way past what a netbook can be expanded to do even light 3d work. That and the resolution and size of the screen would make me question your statement. If you are doing anything real with Autocad Yes going to C2D and an Nvidia gpu will make you a lot more productive. And unless you work for free it will pay for it's self in a short amount of time Frankly You would be better off with any number of non netbook Wintel machines for that matter over a netbook for doing Autocad. Yea sorry but you lost me with the Autocad statement. Using Excel and email sure no problem. DVD transcoding... Not for work and you must have a lot of free time...
Netbook. CPU Atom. GPU Intel intergrated graphics. 1 GB of ram. Low resolution screen. Slow hard drive or slow SSD. Plastic case. Windows 7 Home Essentals or XP Cheap price
Apple Air and other Ultra portables CPU C2D or Core i3. GPU for the Air Nvidia and it supports OpenCL Higher Resolution screen. 2 or more GB of ram. Fast SSD Metal case or Carbon Fiber for the Sony OS/X or Windows 7 profesional or Home Premium A price =>$1000
They are really not the same thing class of machines and the Air isn't the first in the class or most expensive.
Actually it is an ultra portable and compared with other ultra portables like the Sony X series it is not bad. In fact it is a good bit cheaper than the Sony. Netbooks tend to have an Atom this has a C2D. It has a fast SSD, long battery life and an nVidia graphics card that supports OpenCL. Yea it isn't a super cheap netbook or your typical $499 laptop it is an ultra portable and fits right in with other ultra portables as far as price and performance goes. Add in the fact that Apple gets very high marks for support in to the mix and it really isn't a bad deal.
Just because you can go to BestBuy and pick up a cheap laptop and run PC decrapify on it and make it work for you doesn't mean that this Air is a bad value. You may not be the target market for it.
I have not tried Minecraft yet so I had no idea it was written in Java. Wow I wonder if that will slow down the "Java programs all suck" FUD. Actually I have very mixed feelings about Apple dropping Java support. Java support on the Mac is super integrated and really does just work most of the time. The downside is one of my Java applications was failing on the Mac and for the life of me I could figure out why. Then Apple pushed an update and all was well. I was testing on Windows and Linux with no problem but on the mac... I will say that Java programs on the mac actually look better than on Linux or Windows. I believe that Apple did a better job at integrating the Java UI with the Mac UI than Sun did with Windows and or Linux. Frankly on Linux it is a matter of which UI as much as quality. I hope Oracle steps up and produces a very good OS/X version of Java.
Easy. Apple followed the rules. The did extend Java but did it in way that didn't break portability. Microsoft made an incompatible Java in violation of the agreement with Sun. They added all sorts of "windows only" features.
We do have them. The problem with rare-earth production is that it also produced Thorium. Of course the Thorium was there to start with and it can be used as a fuel for nuclear reactors but we currently see it as a problem. Silly humans. Time to start working hard on Thorium cycle reactors and then we can get rare earths as a by product of extracting fuel for our safe clean nuclear reactors. And honestly the EPA really has done more harm than good over the years. Most of you are not old enough to remember the bad old days when rivers caught on fire and the great lakes where heading towards being dead. Things are not perfect but better than they where and probably a lot better than they would have been otherwise. And yes the EPA isn't perfect and sometimes can go too far or is heavy handed but over all they have done a lot of good.
LTO is more reliable for archive then a hard-drive. And it is pretty hard to have an off site backup with a live RAID. Not impossible mind you but shipping them to Iron Mountain or taking them to your bank and putting them in a safety deposit box is pretty easy. Also disaster recovery. What happens if your office burns down? Or if you have a massive power surge? Tornado? Hurricane, or a computer virus that destroys your data?
In a real IT setting you will have a RAID, onsite backup, and an offsite backup. And even with a RAID you may have your RAID array mirrored to another array and you will have several hot standby drives in your array just in case. You could have a blizzard and have a drive in your array go down. A hot stand by means that you will not be running with out redundancy for any length of time. Externals do have a place but not for in a serious datacenter. If your data is worth millions or millions of dollars then a few grand for a tape with library will be no problem.
It sounds a lot like a phased array to me. Not really new. And why? Well some people might not like the look. They will fair better in high winds and with snow loads. Also they will work much better for vehicles. Combine it with a GPS and it can track a satellite while you move. It could also switch between satellites on it's own. In theory you could even use it with none geosyc satellites. As one comes into view you could switch beween them in a very rapid mannor. That could allow for a much lower latency internet connection and or higher bandwidth as well as working in places where a geosync connection is difficult like near the poles.
What I find so interesting is that people will dismiss that he might actually be guilty. That what none of his fans realize is that practically nobody know who the heck he is. There is just a small group of use that does know the masses do not know or really care. If he died tomorrow in an accident 98% of the population if not more wouldn't remember him in six months. A few tragic hipsters would wear tee shirts with his picture on them but the vast majority just wouldn't care.
You do know that the US did fine some Chemical weapons don't you? You know the ones that where supposed to be gone. Not that masses that was thought to be their but still some.
"Christ, I live in the UK and the US hoodwinked us into partaking in a possibly illegal war" Wow and you can not even put any responsibility on your own government... It is the US's fault and your nation is yet another poor victim of the evil US. Really? Yes the US is the Boogieman.
I think it is the Boogieman.. Oh wait same thing. It could also be that he really did sexually molest someone in sweden and they just don't want him there. I mean if the US really could control every other nation on the planet like people on slashdot think then he would have had a tragic car accident long ago.
But the sad thing is that I really do like Linux the best. I am just not going to try and fool myself. Until I can go to a store and there are items that have a little penguin symbol on them that says works with Linux V 2.x and above we are just stuck.
Really it sounds like something you would hear about in some super "liberal" area of California or Santa Fe New Mexico. Some child has a miss aligned aura and Wifi is to blame. Poor kid had to get aromatherapy for a week to get back to normal. Sorry Canada just glad it isn't us this time.
I use Linux and OS/X and Windows so I must ask what is hard to do on a Mac? Really I have had a very small learning curve and I have not been stopped from doing anything yet. So an example would be nice. And no it isn't just major studio games that are lacking. A good professional CAD system. An office package as good as MS Office. Office is still better than OO.org. It is just that OO,org is a better value. Photoshop. Sorry but Gimp is good and even better than Photoshop Elements but it isn't better than Photoshop for high end use. A video editor as good as the offerings from Apple, Adobe, and Sony.
And here is the big one. Device drivers! Linux's hardware support is actually very good but it needs a stable binary device driver interface! Companies want to put a simple to install driver on the CD with the devices you buy! They do not want to force customers to install a compiler and Kernel sources! Not only that but they do not want to have to wait for the driver to make in to the kernel.
That is is a killer issue for Linux on the desktop right now. If the hardware you buy isn't supported your in a world of hurt. Oh and "checking before you buy" is not so easy. Take wifi for instance. The list of supported devices is by chipset! Boxes often do not list the chipset and they can even change over time.
Please don't take this the wrong way because I appreciate your gracious and very rare reply. Why where you so sure I was wrong? Even the article said that their was no core on board. Was it just the idea of someone crawling into a bomb bay with a core and inserting it into a bomb is just too outlandish? Truth is that at the time things like safety where viewed in a very different light. I think people where more willing to take personal risks in service of their nation than we are today. And after the losses in World War II we where much more tolerant of training loses than we would be today. Frankly the B-29 was not a very reliable aircraft by todays standards and the B-36 that replaced it had a bad habit of catching on fire.
The problem happens when some decides that their truth is more important than the facts. Or to put it simply the ends justify the means. Think about all the flat out lies that have been told by extreme environmentalists. That Katrina was the caused by Global warming is one of the big ones. Or this anti nuclear article. The first story about Travis is so bad it is funny. The plane crashed "it happens" and it was carring a bomb shell that blew up. If it there had been a core on board "which almost never happened" and if the core had been in the bomb which it never was and if the bomb had produced a symmetrical implosion because of the crash we could have had a huge tragedy. So an extremely rare event "a core on board", an impossible event "The plane taking off with the core installed", and an extremely unlikely event "the crash actually causing a full implosion" all had to happen. Really? Yes I fear that we are seeing the end of moderates in the countries dialog. If so we are in so much trouble.
It can but the real limit to efficiency on small gas turbines is the gap between the the turbine blades and the housing. The smaller the better but it is a ratio between the turbine size to the gap which really counts. So on say a big airliner where the blades may be say two feet across "I am talking about the actual compressor and turbines and not the main fan" You could will see very tiny gaps. Now try and scale down to a turbine of only 2" across and you can see the problems.
Not anymore. The "trick" is to get the gases out of the combustion chamber as fast as possible and start expanding them. As you get work out of the gas it starts to cool very quickly. NOx is a much bigger problem for diesels where you keep the gas at a high temperature for a much long amount of time.
A modern gas turbine is not that far off from an internal combustion engine in SFC at peak power. They tend to be weakest at part loads. Also you are not really working out the full fuel economy numbers. AVGAS is a lot more expensive than jet A and the H-34 probably would like something a little better than 100LL for full performance. Gas turbines are much better for helicopters than pistions once you get above 300 or so HP.
Yes but I just wish that Slashdot editors would understand that if the summary contains any of these words, "Republicans, Demarcates, Congress, Senate, or White House" that it is politics. Unless it is about the CMS their website uses.
I have to say that I feel your pain but Slashdot still has the best comment system. The comentes on CNN and Engadget are much worse. Slashdot has a real slant and once you get used to it you just deal. They are anti-nuclear, anti-religion, anti-Republican, anti-DMCA, pro-Linux, Pro-FOSS.
If you ever find a site that is better or even can tell what is politics and what is not "I have the Politics listing blocked but the editors don't know what is politics and what isn't" let me know.
Actually everything I said makes perfect sense. That bomb was just the shell. It had no core. For the longest time the cores where locked away and under the control of the NRC. The Air Force didn't have control over them and in 1950 only trained with the shells. And yes they did assemble them in flight. As a safety system the core was not installed in the bomb until they where well on the way to the target. From the wikipedia http://en.wikipedia.org/wiki/Mark_4_nuclear_bomb " In addition to being easier to manufacture, the Mark 4 introduced the concept of in flight insertion or IFI, a weapons safety concept which was used for a number of years. An IFI bomb has either manual or mechanical assembly which keeps the nuclear core stored outside the bomb until close to the point that it may be dropped. To arm the bomb, the fissile nuclear materials are inserted into the bomb core through a removable segment of the explosive lens assembly, which is then replaced and the weapon closed and armed." So as you can see not armed == no nuclear material in it and yes they can and did put it together in mid-flight. .
