微軟首度展示Windows Server 8多項核心功能，不需共享儲存，也可以同時進行多個虛擬機器的線上轉移，遠端虛擬桌面也能支援觸控操作

微軟在Build研討會中釋出新一代作業系統Windows 8和Windows Server 8的開發者預覽版本，也首度揭露Windows Server 8開發者預覽版的核心功能，除了內建Hyper-V 3.0新版外，強化了線上轉移功能，不需共用儲存可同時讓多臺虛擬機器線上轉移，也提供了多達上千個PowerShell指令和新版的伺服器管理平臺，可在單一管理介面中控管多臺伺服器，讓企業更容易調度各種Hyper-V的虛擬化資源。不過，微軟表示，預覽版本功能未來也可能異動。

微軟伺服器和雲端部門副總裁Bill Laing表示，微軟從過去推出的公有雲服務中累積了各項系統經驗，來開發Windows Server 8的新功能，讓Windows Server 8能夠成為企業打造私有雲的利器，其中包括了虛擬化功能強化、多伺服器管理機制的簡化、多租戶網路架構設計以及多媒體的遠端虛擬桌面機制等。

不用共享儲存，可線上轉移多個虛擬機器
Windows Server 8內建了新版Hyper-V 3.0，最高可提供32顆虛擬處理器和512GB記憶體的虛擬機器，也新增虛擬光纖通道的支援，可在虛擬化環境中建置虛擬SAN。Windows Server 8內建了新版Hyper-V 3.0，最高可提供32顆虛擬處理器和512GB記憶體的虛擬機器，也新增虛擬光纖通道的支援，可在虛擬化環境中建置虛擬SAN。

除此之外，另一個虛擬化功能的改善是VM線上轉移（Live Migration）機制的增強，過去一次只能線上轉移一個虛擬機器，現在則可以在虛擬機器不停機的情況下，在線上同時進行多個虛擬機器的搬移，而且線上轉移時，不需要先建立共享儲存。只要兩臺伺服器之間透過網路連結，就能將第一臺伺服器中的虛擬機器線上轉移到另外一臺中執行。此外，也新增了虛擬儲存空間線上轉移的功能。

虛擬桌面功能則大幅強化了多媒體功能，包括了遠端3D圖像支援、遠端觸控支援和遠端USB支援，讓使用者可以透過不同的行動裝置來操控伺服器提供的虛擬桌面環境。

另外系統控管機制也有新功能，除了能在單一平臺中管理多臺伺服器以外，還提供了新的資源監控介面，錯誤控管機制則增加了如Guest應用系統健康監控、VM硬體錯誤隔離、VM當機時轉移優先排序、支援信任開機等新功能。

微軟已經開放下載的Windows 8預覽版，包括了Visual Studio 11預覽版本，和Team Foundation Server 11的預覽版本，以及.NET Framework 4.5，而Windows Server 8預覽版則只開放給MSDN用戶下載。

Windows Server 8核心功能

● 虛擬化：VM支援32顆虛擬處理器和512GB記憶體、VHDX格式最大達16TB、Hyper-V最大支援2TB實體記憶體和160顆邏輯處理器。單一叢集最大支援63節點和4,000個VM。可多VM線上轉移，新增Hyper-V Replica可線上複製VM、線上儲存轉移、線上VHD合併，以及支援虛擬光纖通道等。

● 管理機制：上千個PowerShell指令，包括了PowerShell命令的Rest API、150個Hyper-V PowerShell命令、儲存機制命令、網通機制命令、可移除Shell和IE、多機器管理協定、PowerShell和系統功能的作業流程整合。

● 網路機制：Virtual NIC監控模式、SRIOV Networking、多租戶網路架構（包括Port ACLs和防火牆）、支援Virtual NUMA、NIC Teaming等。

● 多媒體遠端虛擬桌面：VDI、RemoteFX、遠端3D圖像支援、遠端觸控支援和遠端USB支援。

● 監控機制：新資源監控介面，包括處理器、網通、儲存計量機制和儲存空間管理的監控。可在單一平臺控管多臺伺服器。Guest應用系統健康監控。

After playing almost 20 years with POG, it’s finally time for me to switch.

I’ve tried various spin-centric like rackets such as Babolat AeroPro Drive Cortex GT, Yonex V Core 100 S / Yonex E-Zone 100. Finally I’ve located my ultimate weapon which is Head YOUTEK IG Extreme Pro. The 16 x 19 familiar String Pattern is what I like the most about this racket as it’s exactly the same as my old POG. Well, POG was one of the best spin generating rackets back in the 80s, but as tennis technology has advanced by so much in the past 20 years as well as my age/fitness, so it’s finally the right time to experience the difference.

IG Extreme Pro is a very different beast in terms of stiffness mainly. Comparing to POG, IG Extreme Pro is 75 vs 62, people always say POG is one of the most arm/elbow friendly racket which I couldn’t agree more. Therefore, I am afraid putting poly strings on IG Extreme Pro is going to hurt my arm.

After taking the advices from the local pro shop and my tennis partners, I’ve selected Tecnifibre-NRG2 Gauge 17 (1.24), a multifilament string that supposed to be much softer and arm easy than Luxilon Alu poly. In additional, I didn’t go with the combination of Poly+Multi due to the same reason that IG Extreme Pro is quite a stiff racket. (ie, stiff racket + stiff poly string = tennis elbow). So the final specification is Main 58lbs and Cross 60lbs.

Finally, my tennis partner said POG is good for hitting flat balls, it’s good for spin due to it’s enormous string bed (107), but it did reach the end in modern tennis game which involves much more spins.

I am going to try this racket next Monday and report back my experience shortly.

Specifications:

Head Size: 100 sq. in. / 645.16 sq. cm.
Length: 27in / 68.58cm
Strung Weight: 11.7oz / 331.69g
Balance: 4 pts HL
Swingweight: 321
Stiffness: 75
Beam Width: 24mm / 26mm / 23mm /
Composition: d3o / Innegra / Graphite
Power Level: Low
Stroke Style: Full
Swing Speed: Fast
Racquet Colors: Black / Yellow
Grip Type: Head Hydrosorb Tour
String Pattern: 16 Mains / 19 Crosses
Mains skip: 7H,9H,7T,9T
Two Pieces
No Shared Holes
String Tension: 52-62 pounds

Tecnifibre-NRG2 Gauge 17

Update: Oct 5, 2011

After using Head YOUTEK IG Extreme Pro for 2 hours, I would say it’s definitely one of the most amazing experiences in my tennis history. I can produce some of the wildest forehand shots from the baseline, volley at the net no longer goes long or twists like my old classic rackets. The most noticed area is my serve as IG Extreme Pro is able to produce a lot more spin and power than before. I do think I raised my game by another level 50% due to changing of the racket.

However, I do find the racket is quite head heavy as described by most reviews, other than that, it’s the perfect weapon as expected.

Update: Nov 13, 2011

Tecnifibre-NRG2 Gauge 17 was broken today after just 24 hours tennis session, wow! THIS IS TOO FAST AND TOO EXPENSIVE, I must admit Head YOUTEK IG Extreme Pro indeed a string eatting monster. I am going to pro shop tomorrow and ask for advice, probably choosing Gauge  will help.

Update: Nov 14, 2011

Today I went to the pro-shop and asked around, apparently, Tecnifibre-NRG2 is one of the most popular and cost effective multi around.

So instead of going to the route of Poly (Main) + Multi (Cross), I simply use Tecnifibre-NRG2 Gauge 16 for Main and Tecnifibre-NRG2 Gauge 17 for Cross, tension is still 58 (M) and 60 (C).

Finally I noticed one negative thing about multi is multi loose tension badly after a few hits (probably 10 hours session), they start to feel like very fragile and a totally different string comparing when they are newly strung, well I don’t really care as long as it won’t hurt my arm.

* A tennis mentioned last month “I now play with alu power + x-one hybrid. plays very well and last bit longer than full multi-filament.”

Well, if this new combination broke under 20 hours, then I will definitely give it a 2nd thought switching to his recommendation. Still my NRG last twice longer than his NRG, this must mean something (ie, he’s a powerful aggressive player)

Update: Dec 13, 2011

Damn it, I broke the string again in less than 16 hours, seemed my new combination will shorten the string’s life, ok, I will use Gauge 16 Tecnifibre-NRG2 for both Main and Cross next time or simply use a hybrid  instead (Poly for Main + Multi for  Cross)

Oh the feel of NRG2 is  amazing, even before it broke, definitely one of the best string I’ve ever  played, only it’s too expensive to keep. (ie, re-string at least once a month)

Update: Dec 23, 2011

I am going back to the first choice, Tecnifibre NRG2 Gauge 17 for both Main (58 lbs) and Cross (60lbs) and see if this time it can last for more than 24 hours. If it still breaks too fast, I simply switch to Poly, hard poly for main and soft poly for cross next time.

Update: Jan 21, 2012

Well, the previous combination Tecnifibre NRG2 Gauge 17 for both Main (58 lbs) and Cross (60lbs) didn’t last even for 14 hours,  it’s the cross got broken this time.

I am really getting frustrated as less and less duration the string lasts, so I went back to pro-shop today and asked them to simply switch to Tecnifibre NRG2 Gauge 16 for both Main (58 lbs) and Cross (60lbs), hopefully, I can reach 20 hours this time.

Update: Mar 20, 2012

The previous Tecnifibre NRG2 Gauge 16 for both main and cross did last almost twice longer, but it felt almost dead when reaching the end. The funniest thing is I didn’t break the string, but it gave up by itself automatically last night when sitting in the corner.

Anyway, I’ve tried to hit my other spare Extreme Pro with Black Code which is a full poly with excellent result and feel, I think I will switch it completely to Black Code for both of my rackets. I do have concern using full poly as they tends to hurt arms of many, but since Black Code is a very soft poly string, so let’s see.

Update: Mar 28, 2012

Poly is definitely hurting my arm and shoulder, so I’ve decided to switch back to NRG2 multi with Gauge 16 for Main (58lb) and Gauge 17 for Cross (60lb).

Update: Jul 5, 2012

I found Extreme Pro feels the best a few hours before I broke the string, so I decied to lower the tension this time, still the same NRG2 multi, Gauge 16 for Main (58lb) and Gauge 17 for Cross (60lb).

Update: Oct 22, 2012

The previous NRG2 last 3 times longer (ie, 3 months) because I was switching between POG and Head EP. Anyway, I have a new thought today when visiting the pro-shop, since my Extreme Pro is very stiff, why not try to put on a traditional synthetic gut which is very soft. So this time I restrung with Prince Synthetic Plus Gauge 16, Main (58lb) and Cross (60lb), the shop owner told me it may not even last longer than NRG, strange! As my existing Prince Synthetic Guts (15) normally last for 4-5 months, well, will try it out this Friday.

Can’t believe I’ve really made it on the last moment.

It’s a bit short, only 1 hour and 15 minutes, but still what a magnificent show!

Well, I have been using my buddy PIII for over a decade! Seemed I am the odd one now. I have been planning to buy a new desktop with the following features:

• No more DIY, probably a Dell Optiplex (now is 990, not sure what’s after that) with 3-5 years NBD warranty.
• Intel Ivy Bridge, 22nm or i5 >3Ghz, 2 cores is more than enough
• SFF Case with low power usage
• 120GB SSD for OS
• External 3-4TB 7200RPM USB 3.0 Harddisk x 2 (one for data, the other for backup SSD and data drives)
• OS: Windows 8 or Windows 7 Ultimate
• Two Gigalan, one for Internal LAN.
• 8GB Ram
• Cost less than HKD5,000

Hopefully Dell will release an upgraded Optiplex shortly in December.

其實我一直想測試我那台JVC EX-A15 K2的終極解碼效果﹐但苦于過去沒有相應制式的K2 CD所以一直都沒有機會親身體驗。

經過了這幾天的初步網上研究﹐發現原來現今高音質的CD也有那麼一大堆的名堂﹐從HQCD﹑LPCD到XRCD至K2HD﹑當然還有近來才推出最頂級的1比1母帶直刻版。

細想一下就知道如何從中選購﹐其實跟很多商品一樣﹐底層的產品雖然最為便宜(意味普通版CD)﹐但質量也相對的最差。中等價格的質量比底層稍微高1/3(意味LPCD/HDCD)。再上就是價格通常貴一倍以上高級層次﹐當然質量也會有著5成以上的提昇(意味XRCD/K2HD)。如果閣下刻意追求登峰造極的層次﹐那麼就要付出比底層產品貴上幾倍的代價﹐但這不意味質量會同樣的高上幾倍﹐相反只是很輕微地比高級產品提升5%到10%而已。老實說這樣的比喻用在CD上﹐其實應該打個折扣﹐如K2HD/XRCD比普通版CD音質好那麼兩至三成而已。

所以答案相當明顯了﹐就是說K2HD性價比是最高的﹐應該當之無愧了﹗當然CD播放器材也要有相當的級別才可完全發揮出這類高音質CD的動人效果。

K2技術其實是日本Victor Entertainment (=JVC)的專利發明﹐直到最近報紙才開始廣泛報道K2HD制式的CD。今年開始環球和Sony相繼推出K2HD CD﹐到今天為止市面上已經超過了100隻﹐但大多數還是以二三十年的經典之作為主。

今天我決定買我的第一張K2HD CD來親身體會一次﹐跑去Hong Kong Records專賣店﹐才了解到原來很多出色的高音﹑歌劇﹑還有Jazz等等精彩種類的CD都沒出過K2HD﹐就是因為K2HD暫時只有環球和Sony出版﹐所以如果表演者不是兩間旗下的藝人﹐那對不起了﹐現都跟K2HD無緣。

盤旋在蔡琴﹑鄧麗君﹑王菲﹑Sarah Brightman之間﹐一直選不下手﹐突然看到這張熟悉的封面﹐當年中學時代的我早已把此卡帶聽得滾瓜爛熟﹐沒記錯的話至少聽了上百遍﹐幾乎完全記得裡面所有的歌詞。

付款的時候差點忘記自己原來是Hong Kong Records的永久會員(因為10年都沒買CD了)﹐打折下來才港幣166塊﹐實在合算﹐比起香港雅虎或者網上商店都便宜了一大截﹐現在才發現以前網店便宜﹐現在世道變了﹐實體店反而更加經濟實惠了。

噢﹐差點忘記選購的時候一定要選背後那些帶號碼的版本啊﹐聽說這些限量頭1000隻的質量是最接近母帶的﹐所有音質也是最好最有保證的。

晚餐後﹐把整間房間的燈都熄了﹐然後靜靜地把CD放近了CD機裡﹐打開了JVC的K2 MODE 1﹐這是相對應CD的增強模式﹐MODE 2則是對應MP3/MKV/FLAC/APE的格式。

奇妙的事發生了﹐哥哥的聲音竟然細膩得如此栩栩如生﹐就像當年我們在紅館聽Leslie現場表演一樣般的動聽。尤其是那幾首近乎清唱格調的歌曲﹐如“由零開始”﹑“烈火燈蛾”﹐還有“需要你”﹐原來這麼多年後還是最喜歡“情感的刺”這首﹐好80年代張國榮Feel﹐好鍾意﹗

K2HD的表現完全沒令我失望﹐我承認可能是心理因素加上K2HD的廠機JVC K2的硬體解碼技術和那對眾所週知人聲特別漂亮的JVC挑木製Wood Cone喇叭的效果﹐所以才覺得這次K2HD CD的效果與眾不同。其實坦白說最大的原因還是當年我聽的是Sony Walkman的卡帶﹐當然跟K2HD的效果可以用天淵之別來形容了。

很多Hi-Fi發燒友至今仍然認為黑膠大碟Analog的魅力乃世間最強﹐這個我絕對同意﹐因為小時候有幸碰過老爸的那套山水黑膠Hi-Fi﹐體驗過什麼是正宗黑膠細緻的韻味。但無奈打理和保養黑膠碟實在太費功夫了﹐所以現在還是傾向于數碼音響為主﹐無它﹐因為實在方便嘛。

22年前﹐他是那麼的英俊瀟灑﹐迷倒了我們一批又一批的男女哥迷們﹐22年後的今晚又再次聽到了這把久違了的磁性聲線﹐我承認我被再次感動了﹗

JVC K2高音質母帶處理技術的過去，現在，與未來 (轉文)

與JVC國寶級大師 桑岡俊治 暢談K2技術
文/林家樑

發問人：高傳真蒲總編輯
受訪者：JVC XRCD K2 技術資深工程師 桑岡俊治先生

Q：請大師簡單跟我們說明，當初JVC最早想要發展XRCD這種精密的數位音訊處理技術，原始的出發點為何？

Ａ：傳統認為數位錄音，訊號是可以完整拷貝而無遺漏或失真。不過，實際操作時卻發現事實並非如此。在東京的JVC青山錄音室中，經常發現前一天的錄音與今天的錄音對照，音質截然不同。理論上，單純的數位拷貝動作不應該有所失真才對？後來經分析發現，從母帶到壓片的過程存在許多影響變數。基於此，JVC開發出XRCD處理技術，最初的原始動機便是：如何將母帶轉換過程中流失的訊號補正回來，真正做到傳遞拷貝不失真，讓數位錄音也能完美保存。以最接近原音精髓的方式製作母帶，讓消費者聆聽與母帶相同的音質。這是經過多年的研究，才發展出的技術。

Q：所謂的K2技術包含哪些處理層次呢？

A：JVC從1987年開發K2介面(Interface)數位訊號傳遞技術以來，目前共分為兩大區塊發展，其一為K2高音質數位信號傳送技術（包括K2 INTERFACE），另外則是K2高傳真資料處理技術(包括K2 HD CODING與最新的NET K2)。

Q：市面上有很多唱片，例如蔡琴的專輯，同一張唱片會出現一般版本、K2、XRCD版本，每張聽起來音質都不一樣，當然XRCD的聲音最好。據了解，XRCD一定要交給JVC專門生產？

A：XRCD必須得交由JVC錄音室作專門處理，因為XRCD有一條嚴謹的生產流程，從母帶的處理到碟片的壓製，皆有極為嚴苛的生產規範。如果從過程中發生什麼閃失，即使再細微，我們都必須重新操作。正因為如此繁複與講究，一般CD製作是達不到XRCD所能呈現的音質。

Ｑ：K2的生產過程也必須交由JVC處理嗎？

Ａ：不用，只要不屬於XRCD等級的K2技術就無須在JVC工廠內製作。

Q：K2也屬於母帶處理技術？

A：K2技術的運用面很廣，目前已衍生運用在三個方面：軟體生產、音樂內容製作，以及流通媒介如光碟生產等。

Ｑ：剛剛先生說K2不需強制性在JVC工廠內製造，那麼目前全世界有幾處STUDIO可以製作K2的母帶？

Ａ：目前美國洛杉磯跟紐約已經有我們的據點。

Q：那麼歐洲呢？

A：目前歐洲市場已經在著手規劃，就在今年一月份法國坎城國際MIDEM 展示會中，JVC特別設攤位推廣K2相關技術，獲得相當大的迴響，日後即將會有我們的新據點。

Ｑ：在台灣，唱片業相當難經營，新聞局曾經舉辦一場座談會，邀請許多相關業者，集思廣益討論是否有增加唱片附加價值的方式。他們請我去演講，我很詳細地將XRCD的精神，製作過程全都介紹給業者。結果，有些業者經營唱片幾十年還不曉得有XRCD此一格式；同時，有許多業者對XRCD興趣勃勃，一旦我談到XRCD每張要賣30美金以上時，他們就立刻興致缺缺了。

之所以分享這個故事，我想說的是：XRCD如果要持續推廣的話，價格部分似乎將會是一大阻礙。

A：或許可以請總編將JVC最新研發的K2 HD CODING(以下稱K2 HDC)高音質編碼技術，介紹給台灣的唱片朋友們認識。

Q：什麼是K2 HD CODING高音質編碼技術呢？

Ａ：簡單來說，一般CD格式僅能紀錄20KHz以下，不過，自然界的聲音構成是遠超過20KHz範圍的，甚至達100KHz，所以說要如何突破CD格式，而將超高頻的部分還原的CD的錄音之中，這就是JVC K2 HDC技術。因此，採用K2 HDC技術就能將DVD-AUDIO水準的音質放入CD格式中，或者將CD提升至DVD-AUDIO格式中，這是相當全方位的新進處理技術。

Q：這種採用K2 HDC技術的CD會有特殊的名稱嗎？

A：一定會標示K2 HD CODING的ICON。

Q：一般CD播放器也能播放K2 HDC唱片？

A：因為K2 HDC只是母帶後製處理的專業技術，並未改變CD 16bit/44.1K的數位格式，因此無論我們用一般手提音響、床頭音響，或者專門播放器，只要能讀取傳統CD的機種都能播放。

Q：在未改變CD數位格式下，為何會有更好的聲音？這一點是我們比較好奇的部分？

A：以XRCD為例，雖然XRCD的頻寬還是與傳統CD格式一樣，高頻延伸受限於22.05KHz，但利用所謂K2 Super Coding技術，透過精密的演算，我們還是能將更多的聲音資訊放入XRCD中。相同地，K2 HDC也是透過積分演算的方式，將22.05KHz以上對聽覺有影響的成分放進來，讓CD音質帶有100KHz頻寬的特色，以獲得媲美DVD-AUDIO的音質。

Q：目前聽來，K2 HDC把20KHz以上人耳聽不見的細微訊號，拉回到CD格式裡頭，似乎跟我們所認識的XRCD差不多。這樣將超越人耳聽覺範圍，但對人耳有影響的頻率，還原到人耳聽得到的訊號中，必定經過很精密的聽覺心理學作為研究佐證吧？

Ａ：正如您所說，JVC經過許多階段的反覆實驗之後，驗證出那些人耳聽不到的超高頻部分，人類大腦反應還是能感覺其能量的存在，並接受刺激。這意味著：人耳聽不到的部分對聽的到的範圍是有絕對影響。所以，JVC所發展的技術就是把聽不到的頻率反應到可聽見的範圍之中，這樣就能還原真實感。

Ｑ：所以K2 HDC主要是AD轉換部分的演算處理？

Ａ：的確。K2 HDC最主要是將母帶處理中的AD部分轉變成K2 HDC技術演算。所以僅僅藉由這部分的改變，業者不需要花費很大的成本去更換整個產線的設備，只要將原本的AD設備改為JVC K2 HDC就可以製作更高音質的CD。

Q：這是相當新的技術，JVC目前如何推廣K2 HDC呢？

A：目前在日本國內，已經有將近160多張左右的專輯採用K2 HDC。至於海外的推廣，一月份坎城國際MIDEM時，JVC就特地把K2 HDC帶去推廣。
目前，我們第一步的規劃是請業者把母帶提供給JVC部分做技術轉換處理。如果實施效果滿意，預計一年之後將推出實體的K2 HDC機器。

因此，目前台灣唱片業界若有興趣，不妨提供Sample給JVC製作。

Ｑ：K2 HDC接受怎樣的母帶格式呢？

Ａ：即使是CD也可以。

Ｑ：JVC對XRCD製作的母帶要求不是相當嚴格？

A：JVC XRCD要求務必是品質好的類比母帶，這是因為XRCD本身有嚴格的自我要求，因此對母帶品質同樣嚴苛，若非夠水準的母帶，XRCD絕不接受。也因此，市面上所看見XRCD認證的唱片，音質絕對有高品質保證。

Q：印象中，XRCD也曾接受過數位母帶？

Ａ：曾經有嘗試過高品質的數位母帶，不過現在已經停止相關申請。

Ｑ：但是現在幾乎都是數位錄音的時代，類比錄音已經越來越少，將來推廣XRCD的機會不就相形變少？

Ａ：如您所說。目前發展到K2 HDC時代後，我們也在思考XRCD要求如此嚴苛，未來該如何持續發展。

Ｑ：目前全球有出版多少XRCD TITLE呢？

A：大概1000張專輯左右，但這個數字非精準的統計數字。

Ｑ：目前除K2 HDC外，JVC還提出哪些屬於K2技術新的應用開發呢？

A：之前提到K2技術的運用面很廣，除了提供音樂內容製作的K2 HDC技術外，我們也將K2技術應用於線上音樂壓縮檔如MP3的流通，或者手機鈴聲音樂高音質下載等，透過NET K2技術，支援軟體與硬體的優化處理，讓經壓縮後的聲音取得媲美CD高音質的表現。

此外，我們也將K2技術應用在家用音響產品之中，例如眼前這部JVC EX-A3音響組合，內部就搭載了K2 HD Processing晶片，提供K2「Compression Mode」的效果。

Ｑ：我們在去年日本CEATEC展中，就曾見過類似這部EX-A3床頭音響組合，結合了JVC Wood Cone木質振膜與K2高音質技術的試作機，很讓本刊吃驚不已，同時又羨慕日本消費者的家用床頭音響就能有如此高規格的配備。可惜，當時採靜態展示的緣故，無法作更進一步的了解。這次桑岡俊治先生難得造訪台灣，最大的任務就是要推廣這部JVC嘔心瀝血之作，既然如此，請桑岡俊治為我們詳盡的介紹這部支援K2技術的EX-A3，作為此次訪談的重要結束吧！

Ａ：誠如您所說，眼前這部EX-A3正是JVC近期最重量級的一款產品。它的喇叭單體採用全新系列的Wood Cone木質振膜，不僅單體尺寸加大，提升音樂頻寬，最重要的就是內建K2 HD Processing，支援K2「Compression Mode」技術。

何謂「Compression Mode」呢？這是EX-A3獨家的K2 24bit音質補償演算技術，共提供兩種模式。在K2模式一時，可將CD音源提升為媲美DVD-Audio的高音質水準；而使用K2模式二時，則可配合內建的「USB HOST」功能，連接年輕樂迷經常使用的MP3、MP4等個人影音播放器，用來強化MP3、WMA等壓縮音源格式，提升為與CD音質齊的水準。由這兩種模式可知，EX-A3是一部跨越音樂世代，音樂類型的高度理想家用音響組合！

消費者也可以選擇將上述兩項模式關閉，以一般模式聆聽。此時，光以8.5cm的Wood Cone振膜，40W x 2的輸出功率，配合全新類比/數位獨立回授式擴大器（編者按：以數位回授來改善PCM訊號的準確度，類比回授則進一步確保輸出端的類比訊號波形，能與輸入端完全一致，大幅降低傳統擴大機的失真達90%），以及極為講究的低震動CD托盤，避震隔絕的機身設計等，這部EX-A3就足以展現極為細膩、完美的音質表現。

而且，Wood Cone EX-A3是經過JVC青山錄音室內資深錄音工程師，與音響工程師共同監督下，以K2技術的精神：還原「原始母帶」錄音音質為目標，進行不斷的調整與最佳化設定。正由於JVC如此看重這部EX-A3，我們保證它所呈現的音質定能符合K2高音質技術的美聲精髓，請各位台灣的樂迷們好好鑑賞吧！

Just another good one from Veeam’s Anton!

Functionality wise, top 3 differences between host based replication Veeam v5 and SRM v5 are:

1. Multiple replica restore points vs. single restore point
In other words, if you don’t spot the corruption immediately, your replica will have absolutely no use. Consider virus infection, or application data corruption – both are very hard to spot immediately.

2. Application-aware image processing vs. basic file-level consistency
We perform application-specific VSS backup step when grabbing the image, as well as application-specific VSS restore steps upon failover (when replica VM is first started) as per Microsoft requirements. vSphere replication just picks up the image without looking inside or trying to meet any Microsoft requirements on how application should be backed up and restored. Exchange webinar goes into specific details using Exchange as example.

3. File level restores from replica
You decide how this is important for you, I know many customers love it.

v6 adds much more stuff to this list (big focus on replication there), but since v6 not generally available yet, it is not fair to use its features as differentiators (even though we are so close!)

SRM is great for storage-level replication and whole site failover orchestration, and our replication is great for smaller scope outages and better protection of individual most critical workloads due to multiple restore points. My take is that vSphere 5 replication is way to basic to provide replacement for our replication (especially with v6 functionality), but neither our v6 removes the need for SRM v5 in scenarios where storage-level replication and site failover orchestration are required to meet RTO and RPO in case of large scale site-wide disaster.

Of course, there is also huge price difference, but that does not matter for you since you already own SRM anyway.

最近發現了個新大陸﹐就是來自澳洲的創作女歌手“Lenka”。開始還以為那把清新感覺的磁性聲線是個青春小女孩﹐原來直覺往往是不可靠的。事實上已經介入中女行列的Lenka可謂大器晚成﹐很多人可能都聽過那兩首朗朗上口的The Show和Trouble Is A Friend﹐但其實她的兩只大碟Lenka和TWO裡還有很多其它意想不到的驚喜﹗最喜歡那些輕快的節奏﹐很有大都市小資的感覺﹐如“Everything at Once”﹑“Dangerous And Sweet””﹑“Heart Skips a Beat” 等。

有點可惜的是錯過了今年二月Lenka在香港的新碟發佈會﹐沒能現場欣賞到她的精彩表演。

咦﹐突然發現Lenka的感覺很像香港本地的一隊Band “My Little Airport”﹐其中最出名的那首“浪漫九龍塘”﹐不知道有否同道中人認同﹖

Update: Sept-25

Lenka will perform live in Hong Kong in Sept 29 (Thur) at the 九龍灣國際展貿中心 (KITEC-Rotunda-3), but HK$380 for 2:30 hours free standing is going to be hard for me, ops…so I guess I just skip it as I can’t queue up as early as 3pm that day like those young kids, too bad!

Despite Typhoon Signal 8, Lenka Live will go on according to schedule tonight, guess what? I got the last minute ticket, Yeah!

This is the real picture (STS088-724-70) from the real NASA web site (http://eol.jsc.nasa.gov/)

When follow the link and click the bigger image, the actual effect is very shocking! Actually, there are 5 more pictures from the same capture time. (STS088-724-65 to 69)

I can’t explain what it is, the most closest explanation is the secret weapon from US or an alien space ship!

Of course the US government can easily make up something like this by putting a space ship image over the original, but why would they do this? But why does US government want to create such a turbulence in pubic by exposing their newly developed secret weapon that doesn’t particular benefit anything financially, politically or similar?

So I can’t think of any motivation behind the making up assumption except it’s the genuine photo.

It could be a Space Junk (could be an abandoned satellite) left there by US or USSR with the possibility less than 1% Actually, there are at least 6 other photos showing the strange shape objects standing still in space from NASA web site.

If it is space junk, then how can we explain the extra ignition fire on left of the body and the three fine aligned lights on the right edge, well it could be the reflection of sunlight, but unlikely.

Btw, one thing is sure, it’s not something an ordinary airplane can reach. This photo was taken from outer space with Spacecraft Altitude: 214 nautical miles (396 km) and the highest record for human airplane is only about 112km, so that’s 3 times more than the best aeroplane can reach.

“The highest altitude obtained by a manned aeroplane (launched from another aircraft) is 111,996 m (367,441 ft) by Brian Binnie in the Scaled Composites SpaceShipOne (powered by a Scaled Composite SD-010 engine with 18,000 lb of thrust) on 4 October 2004 at Mojave,”

(http://en.wikipedia.org/wiki/Flight_altitude_record)

Well, it is just a really blizzard picture with too many question marks after all.

It’s been more than one month since my last appearance on the court. I enjoyed playing again today with my partner, I feel so good being able to come out and play again under the sunshine. 

I started slowly and picked up the pace gradually, worked on my forehand, then backhand, then volley and finally the serve. In particular, I emphasized on my form, not to “late hit” on every single shot and completed my swing motion more fluidly than before, there I see the effect immediately, my shots is more speedy and more spin. Now I regret that I was being so lazy and hurt myself eventually, stupid really!

Finally, I started to use Nike Patella Band for my left knee for extra protection. After the game, I rushed to Gigasport and bought another one for my right knee. The Petella Band worths the investment and it’s only HK$62 after discount, they worked pretty well I must say for my knees that’s getting older every day.  

Well, I simply try to use every possible method to extend my tennis game till 80 years old!
