我之前一直都很喜歡Tecnifibre的NRG2 Multi，唯一的缺點就是不耐用，每個月就要再穿一次，不到20個鐘頭就斷線了，小數怕長計，一年下來算起來幾乎都可以買一只全新的球拍了。後來聽不同師兄的介紹，得知原來Gut線的Hybrid一來手感更好，二來壽命比較耐用，而且透過師兄更加有較大的穿線折扣，長遠來算比NRG2更加經濟實惠。

這次Hybrid的新體驗，感覺Babolat Hybrid RPM Blast 17g + VS Gut 16g的確比NRG2硬，開始很不習慣，經過了一個多鐘頭兩種不同的線不停地摩擦結合後才漸入佳境，慢慢感覺到了VS Gut的手感和RPM Blast的Spin。

Babolat VS Gut不用多說，手感控制當然一流，其實看見不少朋友們都會用塑料袋裝起腸線球拍，目的是防潮。但是現今VS Gut的最新Thermogut科技已經做到防熱和防潮，我認為放在塑料袋反而會困住了濕氣，對Gut造成負面影響。

雖然大家都是Poly，但因為Babolat RPM Blast擁有獨特的八角形相比起Tecnifibre Black Code的五邊形更加咬球，從而大大增加球停留在線床的時間，所以打起Top Spin來更加得心應手。

Poly線出名硬，有不少師兄都曾經深受其害(網球肘)，尤其是Luxilon Big Banger，所以很多都不約而同地推薦較為軟身的Poly: Black Code就是這個原因，有說跌磅的Poly也是造成網球肘的元凶之一。另外聽說這次的RPM是”Team”版本，也就是Babolat所有”Team”版本都比較軟身和令到擊球更加舒服，也就是Arm Friendly。

另外就是兩副線都是黑色，連VS Gut (Babolat VS Natural ThermoGut 16 Touch String Black) 也用了罕有的黑色Coating，配上我那只Head YOUTEK IG Extreme Pro黃黑的Paint Job，的確好鬼型，哈哈。

我這次的選擇是Main用VS Gut、Cross用RPM Blast， 同是55磅，目的當然是想比較耐用。相反的話(Main用RPM Blast、Cross用VS Gut)手感肯定會較好，但是球線的壽命也會大大縮短。

根據觀察朋友使用的經驗來推測，這樣的組合應該可以維持至少2-3個月，當然Poly的RPM Blast的磅數應該已經全掉光了，其實這是所有Poly的死穴，就是從穿完線那刻就開始跌磅，聽師兄說最近出了一隻金色跌磅比較慢的Poly，這是一個好的開始，當然也有人中途再穿過一條新的RPM Blast(Cross)來維持整體磅數，但我認為這是多此一舉。

另外這次的體驗Hybrid開始不再用Damper，完全感覺到了純淨的感覺，很喜歡，現在覺得加了Damper後擊球的時候好像總是隔了層什東西的感覺，不知道你們有沒有同感﹖

其實兩年前我就曾經自行Mix過類似Hybrid，當時的選擇是Babolat Natural Gut (Main)加上Gamma TNT2(Cross)穿在Price Original Graphite Oversize上(一只超Classic和Flex的板)。手感好是好，但是就是代價不菲，因為不到一個月就斷線了，心疼死了，那次經驗實在太奢侈了，所以之後都沒有再穿過腸線。

最後在網上查此線資料的時候才發現原來Babolat Hybrid RPM Blast 17g + VS Gut 16g正是Nadal的選擇!

What can I say? Riverbed Stingray Traffic Manager (previously know as Zeus Traffic Manager)  is probably one of the best Load Balancers I’ve tested on the market, now it’s also available as VMware OVF format.

From initial VM OVF deployment to the actual implementation of the first load balanced web sites was less than 30 minutes. Simple concept and solid performance during stress tested (concurrent over 10,000 users per seconds).

I particularly like the admin GUI, simple and intuitive, everything is self explanatory and no non-sense.

What’s best, it also comes with an integrated Application Firewall as well as Traffic Manager Cluster Mode which you can add one or more Traffic Managers to the cluster to make it HA, wow, this idea is brilliant!

I’ve even gone as far as adding the 3rd TM (on a different subnets) into the cluster, it worked somehow, but failed when creating a Traffic IP as the Traffic IP must be seen on all subnet, I think this can be easily solved using a router between the two different subnets thought. Alternatively, I think GSLB is my next option on the list, but don’t have time now, will try later.

The most magical feature is Aptimizer which transparently optimize your web page (ie, compressed, hence reduced the time for loading) without you rewrite any of the coding.

Stingray Aptimizer is what was formerly known as Website Accelerator, or WAX. It was created by New Zealand software developer Aptimize to rejigger and accelerate web pages running on IIS or Apache web servers as well as pages stored on content delivery networks from Akamai Technologies.

Aptimizer analyzes how web pages load and reorganizes the content so a web browser doesn’t have to make so many roundtrips back to the web server to load a page. Because there are dozens of elements on a typical page, reconfiguring the web pages on the fly and storing the more efficient web page in cache on the web server can reduce page load times by a factor of four. The beauty is that this optimization does not change the web applications one bit, so you don’t have to modify your code.

The only complain is probably the cost, which is prohibitive to implement for the average SMBs, but since Riverbed is really targeting enterprise market, so I guess they don’t really care about the little ones after all.

Oh…there is a free and fully functional with limited features (10 request per second) Developer edition, don’t forget to try it out.

如此誇張的輪殼出現在最新款的Porsche Panamera上，肯定吸引了不少街上途人驚異的眼球。

今天有幸品嘗到了超嫩的紐西蘭小羊架，製作方法非常簡單，用Olive Oil和香草腌大概5分鐘，然後焗15分鐘就大功告成，味道超級的好! 覺得比城中名店Sabatini的羊架還要好吃得多! 而且全部成本才$150，太合算了，這個當然要多謝從事食品進出口生意朋友的優惠。

其實烹飪西餐的竅門大部份還得依賴食物的質量，相比起中菜擁有化腐杇為神奇的效果和其博大精深的文化，簡直就是小巫見大巫。

今天早上沒有警車叔叔的例行公事，於是大家都很放心地隨便泊車，包括這台黑夜戰神保時捷996 Turbo!

恭喜! 恭喜!

最近AA推出的LP700藍色嚴格來講仍然不是正宗的林寶Baby Blue，真不明白生產這個柔和的顏色為什么這麼困難﹖

倒是10年前京商的那台罕有Countach QV顏色做正確了。

比較了一下功能，重量以及售價，號稱全副FF的入門版6D明顯是雞肋，比上不足(5D2、5D3)，比下有餘否 (貴過60D很多)。

最重要是十字對焦只有一點，所以對焦太慢，影BB、運動等完全跟不上，還不如EOS 7D。

另外發現兩年前買的那隻APS-C鏡王EF-S 17-55mm f2.8 IS USM售價竟然要9千多，比當初的7千頭還要貴上1/3，看來全拜日圓升值所賜，所以之前有攝影前輩提醒購買高級相機鏡頭是一種保值的投資的確有其道理。

This is the latest recommendation from Dell Equallogic, found in Firmware 6.0 Release Note:

Beginning with this release, the Group Manager GUI no longer includes the option for configuring a group member to use RAID 5 for its RAID policy. RAID 5 carries higher risks of encountering an uncorrectable drive error during a rebuild, and therefore does not offer optimal data protection. Consequently, Dell recommends against using RAID 5 for any business-critical data.

RAID 5 may still be required for certain applications, depending on performance and data availability require-ments. To allow for these scenarios, you may still use the CLI to configure a group member to use RAID 5.

For a complete discussion of RAID policies on PS Series systems, review the Dell Technical Report titled PS Series Storage Arrays: Choosing a Member RAID Policy, which can be downloaded from either of the following locations:

• www.equallogic.com/resourcecenter/documentcenter.aspx

• en.community.dell.com/techcenter/storage/w/wiki/equallogic-tech-reports.aspx

In addition, Dell recommends against using RAID configurations that do not use spare drives. You should convert all group member that are using a no-spares RAID policy to a policy that uses spare drives.

Known Issues and Limitations

The following restrictions and known issues apply to this version of the PS Series Firmware. For information about known issues and restrictions from other releases, see the Release Notes for those versions. For issues about Dell EqualLogic FS Series Appliances, refer to the Dell EqualLogic FS Series Appliances Release Notes. For issues and limitations pertaining to host operating systems and iSCSI initiators, refer to the iSCSI Initiator and Operating System Considerations document.

RAID Conversion From No-Spares To Spares Does Not Work
RAID conversion from a no-spares policy to a spares policy appears to work, but it actually converts to no-spares, resulting in no change. (Funny )

I am pretty happy with SANHQ 2.2, HIT MS 4 and HIT VMware 3.1, and there aren’t much new features I need, so I choose to delay the upgrade for the time being.

Furthermore, there are two interesting videos presented by Dell EQL User Group in Taiwan (in Chinese), the following new features were intensively mentioned as well. (Part 1 and Part 2)

SAN HQ 2.5 Announcement

Dell announces Host Integration Tools for Microsoft 4.5

Dell Announces Host Integration Tools for VMware 3.5

Note: HIT for VMware v3.1.1, and earlier, is not compatible with Equallogic Firmware Version, 6.0, of the PS Series Firmware. A later version must be installed prior to upgrading to Version 6.0, for compatibility.
