Wesley's Tool-Box

마이미츠 2010년 9월 체험 이벤트는 아이폰4용 액세서리 3종 (액정보호지, 차량용 크래들, 책상용 크래들) 이었으며, 저는 그 중 차량용 크래들을 써보게 되었습니다. 정식 명칭은 'REX Car Cradle'이며 GUT Korea에서 제조하고 유레트에서 판매합니다.

1. 구성 및 조립

이 크래들은 위치조절이 되는 흡착판과 휴대전화 본체를 잡아주는 틀로 구성되어 있으며 각각 따로 포장되어 왔습니다.

이것은 블루오션샵에서 나온 BHK49라는 블루투스 무선키보드입니다. 보시는 대로, 두 손을 잡고 엄지로 자판을 칠 수 있도록 만들어진 휴대용 키보드입니다.. 이 제품은 과연 저를 만족시켰을까요? 궁금하시면 계속 읽어보시기 바랍니다.

Point-and-shoot digital cameras have reached the end of the 'megapixel race' at around 12 megapixels, giving you a photo with the resolution of 4000x3000. One of the reasons for this peak is that the typical image sensors used in this class can produce only around 10 megapixels of actual data at best, and even less with internal post-processing applied. As a result, camera's 'actual' resolution will be far less than 4000x3000, even if the 'output' resolution is that large. Increasing output resolution any higher without better sensors would be no better than doing a digital zoom - bigger picture without more detail.

A smart shopper would therefore avoid blindly following the megapixel number on the spec sheet, and instead check the sensor size as well as the actual sample images posted in independent product reviews. In many professional reviews, an ISO 12233 Test Chart(partly seen above) is used to check the actual resolution of a camera. DPReview has been extensively using it.

So, why am I talking about this 'actual' and 'output' resolution today? I carry a nice compact digital camera - Kodak Z1085 IS - and an excellent smartphone - iPhone 3GS - with me at all times. The image quality is good for the given class, and they have the maximum native output resolution of 3648x2736 (10MP) and 2048x1536 (3MP), respectively. But I suddenly got curious as to what their actual resolution would be. Unfortunately, searching the internet did not come up with any resolution testing - it was time to do a little testing of my own...

There had been mentions of Snow Leopard (Mac OS X 10.6) pre-release builds supporting read/write support for NTFS (native file system for current Windows versions). Read-only NTFS support was available since Tiger (10.4) days, so this was an interesting development. Unfortunately, read/write support was apparently dropped in the final release build of SL.

It turns out the support is still there, but disabled by default. This post by Chrysaor at MacRumors shows how to modify fstab to force an NTFS partition to mount in read/write mode. The drawback of this trick is that you have to manually do it to every partition you want to mount, and you need to unmount and remount the partition after applying the trick to get it to work. Hardly elegant, mind you.

Luckily, there is a much simpler and elegant way. Click below to find out.

I've gotten Snow Leopard on the server a week ahead of schedule. Yes, this website is running on Snow Leopard right now. My wife is expecting the baby in a couple of weeks, so I decided to get on with any time-consuming stuff early. The website seems to be running okay, so far...
