CRUD集大成！

Recently I've done a series of posts all related to using Linq in a tiered application:

• Linq Table Attach()
• Linq Table Attach() based on timestamp or row version
• Handling Attach() with child entity objects
• Exploring DataContext in more depth

The various posts (which have been influenced by this MSDN article)have focused on a DataContext that looks like the diagram below.  TheContact class generated has a child collection property of Addresseswhich is of type EntitySet<Address>.  This distinction isimportant because the example deals with a complex object that has acollection of child objects rather than a single object with a bunch ofprimitives.  You must take care to handle the items in the childcollection properly.


The SaveContact() method looks like this:
1:  public static void SaveContact(Contact contact)   
2:  {   
3:      using (PimDataContext dataContext = CreateDataContext())   
4:      {   
5:          if (contact.ContactID == 0)   
6:          {   
7:              dataContext.Contacts.InsertOnSubmit(contact);   
8:          }   
9:          else  
10:          {  
11:              dataContext.Contacts.Attach(contact, true);  
12:              dataContext.Addresses.AttachAll(contact.Addresses, true);  
13:          }  
14:          dataContext.SubmitChanges();  
15:      }  
16:  }

This code works fine when passing a Contact object into your data access tier for any of the following conditions:

• A brand new Contact to be inserted with no child addresses.
• A brand new Contact to be inserted with one or multiple child addresses.
• An existing Contact to be updated with no child addresses.
• An existing Contact to be updated with one or multiple existing child addresses to be updated.

At first, all seems well.  The problem is that there are actually a couple of gaping holes here. Consider this scenario:

• A user of the application creates a brand new Contact (with no addresses) and the code inserts it just fine.
• Theuser then goes to update the existing Contact they previously created.But the change they want to make is the ADD a new address to thisexisting contact.

The above code will throw this exception:  "System.Data.Linq.ChangeConflictException: Row not found or changed."
This is obviously bad.  What is happening is that the AttachAll() onthe contact's Addresses is failing because the Attach methods are meantto be used for updates to rows that are already existing in thedatabase.  In this case, although the Contact is existing, this is abrand new Address that we are trying to insert. So what we need to dois to call AttachAll() if there are existing Addresses or theInsertAllOnSubmit() method if they are brand new addresses. One simpleway to accomplish this is by adding a property to the Address via apartial class:
   1:  public partial class Address   2:  {   3:      public bool IsNew   4:      {   5:          get   6:          {   7:              return this.Timestamp == null;   8:          }   9:      }  10:  }
Here we've utilized our Timestamp column (used for Optimisticconcurrency) to determine if this is brand or or existing (but thiscould alternatively have been done with a simple Boolean). This meansour SaveContact() method can now look like this:
   1:  public static void SaveContact(Contact contact)   2:  {   3:      using (PimDataContext dataContext = CreateDataContext())   4:      {   5:          if (contact.ContactID == 0)   6:          {   7:              dataContext.Contacts.InsertOnSubmit(contact);   8:          }   9:          else  10:          {  11:              dataContext.Contacts.Attach(contact, true);  12:              dataContext.Addresses.AttachAll(contact.Addresses.Where(a => !a.IsNew), true);  13:              dataContext.Addresses.InsertAllOnSubmit(contact.Addresses.Where(a => a.IsNew));  14:          }  15:          dataContext.SubmitChanges();  16:      }  17:  }
Now the code works fine regardless of whether you're adding a new address to an existing contact.
So now, we're surely good to go, right?  Unfortunately, we still have one big gaping hole. Consider this next scenario:

• A user creates a brand new contact and this contact has an address. User saves and everything is fine.
• Theuser then goes to update the existing Contact they previously created.But the change they want to make is the DELETE the existing addressfrom this existing contact.

Now you've got a couple of different choices for how you want tohandle this scenario. IF you have control over the client, you can keeptrack of whether the address was deleted or not. You can add a newIsDeleted property to your Address partial class:
   1:  public partial class Address   2:  {   3:      public bool IsNew   4:      {   5:          get   6:          {   7:              return this.Timestamp == null && !this.IsDeleted;   8:          }   9:      }  10:    11:      public bool IsDeleted { get; set; }  12:  }
But again, the responsibility is on the client to keep track ofcorrectly setting this property. While it is not difficult, it is nottotally trivial either. If you do that, then you can now update yourSaveContact() method to this:
   1:  public static void SaveContact(Contact contact)   2:  {   3:      using (PimDataContext dataContext = CreateDataContext())   4:      {   5:          if (contact.ContactID == 0)   6:          {   7:              dataContext.Contacts.InsertOnSubmit(contact);   8:          }   9:          else  10:          {                      11:              dataContext.Contacts.Attach(contact, true);  12:              dataContext.Addresses.AttachAll(contact.Addresses.Where(a => !a.IsNew), true);  13:              dataContext.Addresses.InsertAllOnSubmit(contact.Addresses.Where(a => a.IsNew));  14:              dataContext.Addresses.DeleteAllOnSubmit(contact.Addresses.Where(a => a.IsDeleted));  15:          }  16:          dataContext.SubmitChanges();  17:      }  18:  }
You now finally have a SaveContact() method that takes care of allpermutations.  And all in all, it's a pretty straightforward 10 linesof code.
If you don't have very much control over the client you might have asituation where the absence of an Address could mean either it wasdeleted or it never existed to begin with. In that scenario, you'regoing to have to blindly do delete/insert on the addresses (i.e., you'dnever run an update on an Address) which would most likely have to relyon looping over the address types and running a line of code like thisfor each iteration:
dataContext.ExecuteCommand("DELETE FROM addresses WHERE ContactID={0} and AddressTypeID={1}", contactID, addressTypeID);While it works, it's pretty clumsy and bordering on a code smellwhereas the first solution was much more graceful. But either way, Icontinue to be impressed with the flexibility of implementation choicesthat Linq provides.

同感。经过了这么多年，Linux改进了不少，windows下面能干的事情，Linux也能干了。
可是就像使用山寨iphone和iphone的区别，用户感受上很不一样。还是iphone用着顺手。

当然这是使用Linux做桌面环境的感受。其实如果使用Linux做服务器，因为已经有高手把脚本写的很到，安装一个什么服务，要做的就是输入一条语句，感觉比Windows还容易，让然这是不出问题的情况下，一旦出问题，要自己解决，Linux高手低手马上分胜负。

所以，如果服务器环境需要用Linux，完全可以用，还可以锻炼水平。桌面开发，就免了吧。

表名称用复数
Contacts
Addresses

实体类名称用单数
Contact
Address

每个表包含两个主键
ContactID （int） / AddressTypeID (int)
Timestamp (timestamp)

主键ID字段命名规则
单数表名称+ID
使用骆驼命名规则，大写每个首字母

采用两个主键的原因是：这样可以用到LINQ的 Attach() 更新方式，用起来比较方便。参考链接 http://geekswithblogs.net/michel ... 7/12/30/118076.aspx
当然在不能够重新建立数据表的情况下，你可以不用这个Timestamp附加主键，使用一个主键，采用传统方式更新数据表。

                    作者        Abel Avram译者        霍泰稳        发布于        2008年10月2日 上午8时3分   
        社区.NET主题.NET框架,IDE标签微软,Visual Studio                          微软最近对外揭开了Visual Studio 2010和.NET Framework 4.0的面纱。
据Visual Studio Team System产品管理部门的总监NormanGuadagno说，微软的下一代开发工具将被简单地命名为Visual Studio 2010，并将基于.NET Framework4.0。VS 2010中值得关注的一个地方是应用生命周期管理（ALM），它能更好地将让开发者融入到应用开发周期中。MSDN上的报道提到VS 2010中主要包括以下新功能：

• 使用新的架构资源管理器（Architecture Explorer）查找与确定已有代码集和架构；
• 设计和共享多种图类型，如用例、活动和顺序图；
• 通过提供能对测试场景更好归档和收集更详细测试数据的工具，有效提高了测试效率；
• 使用新的测试影响视图（Test Impact View）可以更容易地确认与运行与变更代码相关的测试；
• 版本控制能力得到提高，包括受检签入、可视分支和构建工作流等；

未来的VS版本将会基于一套新的建模工具，同时支持统一建模语言（UML）和特定领域语言（DSL），另外还包括架构资源管理器：

Visual Studio Team System中新的架构资源管理器使得开发者和架构师可以根据现有代码创建架构视图，理解代码和架构之间的关系以及它们是如何“工作”的等。

另外一个用来帮助修复无法重现的Bug的工具是Test Runner：

Microsoft TestRunner—是一个独立的工具，测试人员常在它的帮助下一步一步对测试用例进行完整测试。在测试用例开始的时候，Microsoft TestRunner对系统数据进行快照处理，包括操作系统版本、补丁包和其他相关系统数据。进行测试的时候，测试人员可以使用该工具对测试中的应用抓取图片，或者甚至录制测试过程的部分或者完整屏幕视频。当发现问题时，测试人员可以在Team FoundationServer中创建一个新Bug，并附上所有这些附件。对于这些屏幕抓取视频，系统会以测试步骤为书签对它们做完全索引，让开发人员更容易地重现测试人员机器上的错误之处。

VS 2010的另外一个功能是测试影响视图（Test Impact View）窗口，它能使开发人员浏览代码改变的情况下需要运行的所有相关测试。此功能的目的是帮助开发人员，通过运行一个完整的测试集来检查在签入代码的时候所更改的代码是否安全。
微软证实说使用Team Foundation Server（TFS）的项目团队将来肯定可以应用敏捷开发流程。另外，VSTS 2010将会把开发版本和数据版本集成为一个产品。更多的相关信息请浏览Channel 9、新闻稿和MSDN等。

How to Buy Gadgets in China And Not Get Screwedfrom Gizmodo: Top by Elaine Chow
Walletfull of cash and bags at ready, I stood, mouth agape, in front of thefive-story electronics bazaar in front of me. It was one of severaldozen in Shanghai, magical places where floor after floor are filled tobursting with gadget vendors begging you to stop by and see theirwares. Like Circuit Cities on crack, everyone inside is desperate tomake a sale and every price is negotiable. Welcome to the way theChinese—or at least the majority who live in megacities like thisone—buy their electronics.
Just minutes earlier, I had directeda taxi driver to take me to one of the bigger tech marts, the ShanghaiPC Mall, located in the Pudong area of Shanghai.
“Are you sure you don't want to go to a Best Buy? We have those here now,” he said.
It'strue—Best Buy opened its largest store ever in Shanghai in 2006. Sincethen, it's cut the red ribbon on a second outlet and recently receivedpermission from the government to start building four more. But whatwould be the point of me going there?
One of the more ironic qualities of buying electronics in China isthat, despite all components being made here, foreign company goodsstill count as imports. Suggested retail prices are pumped even higherthan they would be in the U.S.... unless you know how to negotiate fora better deal. But Best Buy frowns on bargaining, even in China.
“Youaren't a local. The shopkeepers will tear you apart,” the taxi driverwarned, laughing, as we approached the Shanghai PC Mall.
Well,we'd see about that. I marched resolutely in, and was automaticallybombarded by three sales clerks from three different booths, allhawking the latest notebooks from some of the best knowncorporations—Sony, Toshiba, Dell.
“Come and browse for a minute, maybe you'll see something you like,” said one.
“Go this way, we have a special today that you might be interested in,” warbled another.
“What do you need? What do you want? Tell me, I'll find you a good deal,” the third trilled.
Inevery cubicle-like row is a representative who'll help fix your PCproblems and, if you're not careful, sell you something you don't need.
Ihave to admit, the intensity startled me. Coming from New York, I wasused to aisles of disaffected or otherwise nonexistent employees. Thelast time I'd seen such fervor was when a kid in an oversized blueshirt confirmed that I was buying something expensive and insisted Ineeded a longer warranty. I scuttled off quickly and the threesalespeople automatically turned around to beset the next person toenter.
This time around, I wasn't hunting big game. Televisions,netbooks and DSLR cameras would have to wait until I'd become moreconfident in my chaffering... and had more cash.
Debit cards arestill pretty rare in this country, and credit cards even more so. Mosttransactions still rely, ridiculously, on cold hard bills. To buy adecent laptop, I'd have to stuff my pockets with over a thousand100-yuan notes—Chinese currency's largest denomination.
Every booth sells its own unique mishmash of gadgetry, impervious to categorization or order.
Onthis trip, my list was more mundane, consisting mostly of accessoriesand doodads. I stopped at a booth with at least thirteen brands ofwebcams crowded around an LCD screen. Some were from established nameslike Logitech, others were made by local companies I'd never heard of.After waffling a bit over the specifications of each option theshopkeeper presented me, I asked how much for a simple Chinese-branded3-megapixel number.
“180 yuan,” she said. I paused then responded that I'd actually take it for 100 yuan.
“Done!” She packed it up quickly, grinned and stretched out her hand to take my bill. Damn it.I'd done enough bargaining in my life to know that when a deal isresolved this quickly, I'd probably been suckered. Sure $15 U.S. isn'ta horrible price to pay for a webcam, but who knows how cheap I couldof gotten it for if I'd been a little more ambitious.
I vowed to stick to brand name goods from then on, where at least the obsessive hours I'd spent browsing Consumer Reports and Newegg.com would give me some indication of their true value.
Floor upon glorious shiny floor of stuff!
Withthat in mind, I next tried my hand at nabbing a wireless router. Thistime around I went for something I recognized: an 802.11b/g Netgearthat would run about $40 in the US. The starting price this time aroundwas 300 yuan (or about $45). I countered with 150 and was scoffed at.Employing my best “Well, if you really aren't going to sell itto me for that much, I guess I'll just be on my way” look, I got theclerk to sigh and give it to me for 200 yuan. $10 off the US price andno sales tax added on at the end of the deal. Not too shabby.
Inthe next hours, I haggled over everything from speakers to hard drivesto extra RAM for my laptop (installed for free, with an extra discountthrown in if I left my old memory sticks with them). I came home thatday, arms loaded with new stuff, satisfied with having saved a good 20to 25% off of US street prices.
Yes, those are iPhones (and real ones, too). No, they're not supported in China yet. Don't tell anyone, okay?
And yet, I had also figured out why Best Buy, despite its inherent inability to ever compete on cost, was doing so well over here.
Negotiating for what you want is a pain. Being accosted by vendors trying to convince you that they'rethe ones you should buy from is a mess of stress. Worrying aboutwhether everything will work as promised at home is downright draining.And the funny thing was, I approached the experience as an informed consumer.It must be a thousand times more frustrating for someone with lessexperience, who would undoubtedly realize too late that they paid waymore than they should have.
What Best Buy offers in China is ahaven for the emotionally fatigued. Their stock comes at a heftypremium, but with none of the uncertainties of the tech bazaars. You'llnever turn around and find the next vendor selling what you just boughtfor 10% less. There is no “if only I were savvier” moment. Oh—and ifsomething is wrong with your purchase, Best Buy won't yell at you forbeing a doofus when you return it (well, at least not over here. The Consumerist says things might be different States-side).
Thatkind of psychological assurance has put the company in a peculiarlypowerful position. Despite initially dire predictions, Best Buy'sShanghai outlet is now one of the company's top-10 revenue generators worldwide. This is probably why three of its four new China stores will be located in this city.
Butwould I head there the next time I need a quick gadget fix? Heck no.Somewhere back at the Shanghai PC Mall, there's a netbook with my nameon it. And it's waiting for me to win it in a bargaining battle for theages. Paying retail? That's for sissies.
Who doesn't love bargains (and Jackie Chan)?

35公里 写道 "提起 Google 的下一代 Web 平台 Google Gears，人们对它通常的误解是离线Web应用。然而事实上，Google 的野心远不在此，这个浏览器扩展拥有比离线应用多得多的使命。Google Gears 面世已经超过1年了，最早的版本发布于2007年5月。Google Gears 主要版本历史如下，但总体来讲，一共经历了4个主要版本，每一个版本都有新增的功能。最近一个版本发布于今年8月。Gears 的总体目标是为浏览器带来桌面功能，这是通过为浏览器提供相应扩展实现的，目前支持 Google Gears 的浏览器有 Firefox, Safari, IE，支持的平台包括 Windows, Windows Mobile, Mac OS, 以及 Linux。随着 Google 自己的浏览器 Chrome 的发布，Chrome 用户甚至不必费心去安装这个扩展，Gears 已经内置在 Chrome 浏览器中。 "
Google Gears 的长期路线非常明确：随着浏览器越来越强大，在 Gears 一类的技术的帮助下，人们越来越不必将软件应用安装到桌面。但在实现这个目标之前，Gears 以及类似技术需要在浏览器中真正实现桌面功能。目前，我们已经走到了哪一步？目前，Gears 可以帮助开发者在以下几个方面改善 Web 应用：

• 客户端数据库存储 - 多数交互式网站靠数据库采集，组织，分发信息内容，而传统模式下，几乎所有的数据库都位于服务器端，用户即使做一个小小的动作，都需要在数据库和客户端往返。使用 Gears 数据库 API，网站可以将数据库建在用户的电脑上，使得对数据库的操作直接在本地进行，实现更好的速度与离线功能。
• 客户端网页服务 - Gears 可以将你自的客户端电脑变成网页服务器，当远端的网站服务器无法到达的时候，LocalServer API 可以将在线时缓存的网页推出，这个功能也可以用作加速。
• 桌面快捷方式 - 要让 Web 程序象桌面程序那样工作，它们至少应当可以象桌面程序那样打开。Gears 很容易帮你在桌面上创建 Web 程序快截方式，可以双击打开运行。Gears 让 Web 程序的桌面快截方式比传统的 Web 快截方式更直观，图形质量更高，支持多种尺寸，甚至可以多层堆积，在诸如 Gmail 一类的 Web 应用中，可以通过这种方式直接在快截图标上看到你有多少封未读邮件。
• 多文件同时上传 - 在正常情况下，如果你要向网站上传多个文件，你只能一个一个上传，除非使用一些基于 Flash 或 Java 的扩展。使用 Google Gears 你可以实现一次上传多个文件。
• 地理信息 - 对于那些支持地理信息的移动设备，Gears 可以实现直接在浏览器中获得你当前的位置，geolocation API 可以随时获悉你的地理位置，当然，实现必须通过一个特殊的对话框获得用户的允许以防泄露隐私。
• 后台处理 - 对于那些使用了大量 JavaScript 的 Web 程序，你必须等待 JavaScript 执行完才能继续进行。使用 Gears 中的 WorkerPool API，你可以让那些耗时的 JavaScript 在后台运行，使你的 Web 程序运行更流畅。

Google Gears 开发团队还将实现 Gears 的以下功能：

• 进度条 - 在上传大文件的时候，你需要知道真实的进度，在传统 web 程序中这是无法实现的，除非使用基于 Flash 或 Java 的部件。Google Gears 可以让你看到真正的进度条。
• 断点续传 - Google Gears 将来可以在文件上传中实现断点续传。
• 屏幕通知 - Growl 以及微博客等系统的桌面客户端，如 Twhirl 可以定制桌面通知窗口，在屏幕的右下角滑出，Gears 将在所有网站实现这样的功能。

在更远的将来，我们还可以看到 Gears 对复杂 3D 图形加速，直接使用客户端电脑中的图形加速卡。上传功能可以直接结合菜单系统，在文件上点右键直接上传文件。Web 程序可以随着系统一起启动。 

以下视频来自 Google 的 Chris Prince 在5月份的 Google I/O 开发者大会中做的一个演示，可以很好地对 Google Gears 做一诠释。 

Nik Cubrilovic 的 next generation web 也对下一代 Web 平台之争做了很好的讲述。

Incredible Secrets of the World's Largest Plasma TVfrom Gizmodo: Top by John Mahoney

  MeetDorothy. At 150 inches diagonal, she’s the world’s largest plasmascreen and the biggest direct-view TV ever made, built (and named) byPanasonic. We got to play with her recentlyand as you've seen, it was mind-meltingly awesome. Even thoughfirsthand experiences with Dorothy are akin to filling a leaf blowerwith nitrous oxide to jet-huff directly into your brain, Dorothy'sbackstory is almost as incredible, especially when it comes tomanufacturing, shipping and yes, managing all the electricity needed tofire her up. So even though you will absolutely never own one—exceptfor you Giz-reading NBA stars and platinum-selling rappers—the story ofthe world's most advanced television is a thrill, and serves as acrystal ball to the future of all TV. Come, talk to her. She'sintimidating, but it'll be good for you.
Why "Dorothy"?
There are currently five 150-inch Panasonic plasmas in existence—and asixth for CES 2009 is currently being assembled. They’ve been named,appropriately enough, like hurricanes—starting with A and working down.Dorothy’s number 4, hence the D.
Why 150 inches?
It’s all about the upper limits of the manufacturing process. Panelfactories crank out the largest single piece of “mother glass” theypossibly can, so that they can cut more large TVs per pane ofmanufactured glass. The ultimate size of a piece of mother glass islimited by the glass’s strength and uniformity—how large the thing canget without cracking. Panel makers will always be pushing thisboundary, because the more 50-inch TVs you can get out of each singleassembly-line run, the more money you can make on them even if they'reselling at lower prices in stores.
Panasonic’s previous biggest piece of mother glass was 103 inches (remember?),from which four 50-inch plasmas could be cut. Their new manufacturingplant, Amagasaki 5 in Japan, has pushed the max to 150 inches—enoughglass to birth nine 50-inch plasmas. Dorothy’s as big as sheis because she literally swallowed nine TVs. When manufacturing evolvesfurther, creating even larger panes of mother glass, you could seelarger trade-show sets, provided they fit through the convention-centerdoors. 103 inches, how quaint. And look at that lil' 42-incher, looking fit for bathroom viewing only by comparison.
What’s the resolution?
Typically called 4K, it's resolution is 3996x2160. Even though youcould technically call this 2160p, it's important to recognize thatit's four times as tight as 1080p. Think four 1920x1080 panelsVoltroning together to make something that's 8 megapixels, as opposedto the best current TVs' 2 megapixels. The annoying thing is that theindustry went from measuring vertical resolution—720p and 1080p—tohorizontal resolution—2K and 4K. (More on that here.)
Asa result, watching a 1080p Blu-ray disc upscaled on Dorothy is akin towatching a standard-def DVD upscaled on your HDTV. As you can see inthe shot below, the upscaler uses two pixels to render a one-pixel wideline from a test disc. But at Dorothy’s scale, it’s less about spottingcompression artifacts, which are most visible when you’re close enoughto induce nausea anyway. It’s about getting your face blown off.

How’s it stack up to Pioneer’s Kuro, one of the top plasmas in the game?
As far as motion-resolution goes—the all-important ability to maintaincrisp images while they’re in motion on the screen—it's actuallybetter. According to HD Guru Gary Merson (who was more interested inrunning his calibration discs on the 150 than sticking with us for someCounter Strike, God bless ’im), the 150-incher, even as a prototype, scored a resolution of 920 lines on a 1080i signal. Pioneer’s ’08 Kuros,the next best, scored 900. Our bet is that Dorothy can't best the Kuroin the contrast department, but as you can see from all of our shots,it's no slouch. Check out more performance specs in Gary’s 125-TV mega-guide. Below: Gary testing motion resolution.
How much power does she suck down, and at what cost?
Dorothy is addictedto raw electricity—we’re talking two dedicated 15-amp, single-phase,208-volt lines which produce around 3,000 watts on average. Dorothypeaks at around 7,000 watts of direct consumption. Not exactlyEnergyStar.
If I plugged Dorothy in at my apartment (that is,after removing my second-floor balcony door and window and much of theexterior wall while at it, and hiring a crane to bring the TV in),Dorothy’s juice habit would run me around $1.50 per hour of use, atConEd’s current price of 22 cents per kilowatt-hour. So, after rentingthe Godfather Blu-ray set, factor in about $15 more in electricity charges for watching the whole thing.
How much heat does the thing put off?
We were expecting getting close to Dorothy was going to feel likeputting our faces in a toaster oven. Even standard-size Kuros can feela little warm. But surprisingly, up front, the heat was far fromextreme. It very well could be channeled out the back, but we didn’tsee any industrial-grade heat sinks behind her, either, or hear anyfans blowing away. (Note: We're not allowed to show photographs ofDorothy's rear, though we did have a peek.)
How much does she weigh?
Around 1,700 pounds not including the stand. For comparison, an actualMini Cooper with Adam in the driver’s seat weighs about 2,800 pounds.
How does Dorothy get around?
With great care and difficulty. After her inception at Amagasaki 5,Dorothy and her sisters were tested then sent on the trade-showcircuit. Unlike the 103,they’re too big even for wooden crates. All that protects Dorothy andher sisters from the elements are the thin membranes of bubble wrap andStyrofoam wrapped around them, and the tarp draped over the openshipping cage. That’s all. Here's a fun fact: Only two 150-inchers canfit in a single 747 cargo hold at a time.
Although we saw a 150-incher at CES last January, Dorothy’s first trip was to IFA in Berlinthis September. Afterward, she headed for Panasonic’s North American HQin Secaucus, NJ where we got the chance to meet. She’s due to appear onWall Street today (unfortunate timing for the poor girl) for theofficial US debut, then on to trade shows in Dubai, Singapore and HongKong before returning home again to Japan.
Thanks forthe facts, but what was that about a "mind-meltingly awesome"experience again? Any way to demonstrate that, say with a video of Gran Turismo 5's in-car view?
Why yes we can, and we'll throw in the 42-inch steering wheel for free:

There's more where that came from: check out more hands-on 150-inch action here and here.

甲骨文与惠普合作：系统走向软硬结合
DWNEWS.COM-- 2008年9月26日20:30:10(京港台时间) --多维新闻网

来源：08-09-27 07:39 比特网

　　比特网(Chinabyte)9月27日消息(王允) 一个软件巨头不干正事，开始卖硬件了。

　　在25号的旧金山甲骨文全球大会(Oracle Open World)上，拉里·埃里森向超过四万名参会者展示了与惠普合作的HP Oracle数据库机——Exadata。

　　这台被称为史上最快数据存储系统的机器由甲骨文和惠普共同耗时三年研制成功，在处理4.5TB电话记录的数据时，与现有的设备两台IBM 570服务器和一台EMC CX3-40存储相比，采用HP ORALCE新型数据存储设备仅采用一半的配置，性能就达到前者的28倍;而与一台硬件配置完全相同的NETAPP存储阵列相比，HP Oracle的存储设备性能也惊人地达到前者30倍。

　　实际上这台机器的产品不仅仅有着惠普和甲骨文的努力，Voltaire InfiniBand也在其中起到了很大的作用，保证了数据交换中的速度。

　　事实上，此前我们也看到很多软件厂商与硬件厂商合作，比如联想与微软合作推出预装Windows Server2008服务器等，但是将自己的名字放到产品中的，甲骨文还是第一个。

　　据了解，甲骨文将负责产品的销售与系统支持，惠普公司则负责硬件的交付与服务。由此可见，双方的合作分工是很明确的，产品也将会冠以两家的品牌。

　　前不久NEC与Unisys合作推出的96核处理器服务器则不同。产品尽管是共同研发，但是却以各自的品牌推出、销售。与甲骨文、惠普的合作完全不同。软硬件厂商共同合作的好处是显而易见的：各自发挥长处，使得产品达到最佳。拉里也说：这是为Oracle数据仓库打造的高性能智能存储设备。

　　HP Oracle Exadata的表现也证明了双方合作的成功。就是不知道，这能坚持多久呢?

微软宣布，将在今后的Viusual Studio版本中集成JQuery. 这样，除了微软自有的AJAX Framework外，又多了JQuery可用来编写Javascript.

Nokia也宣布了将在其Web Run-Time平台中集成JQuery，使今后手机应用开发者可使用JQuery的功能。

连着玩了二天，挺不错。合理性方面比以前强。

中国老百姓喝着三鹿牛奶，赚几毛澳元一个小时的工资，帮小日本做PS3的配件，然后小日本在当整的卖，一台机器不知道赚多少钱，该砸。
