      Early in my career, when I worked as an engineer, my boss had a process by which the engineering team was expected to report project status. He insisted that we use the following steps, in the specified order:

      1. Punch line: The facts; no adjectives, adverbs or modifiers. “Milestone 4 wasn’t hit on time, and we didn’t start Task 8 as planned.” Or, “Received charter approval as planned.”

      2. Current status: How the punch-line statement affects the project. “Because of the missed milestone, the critical path has been delayed five days.”

      3. Next steps: The solution, if any. “I will be able to make up three days during the next two weeks but will still be behind by two days.”

      4. Explanation: The reason behind the punch line. “Two of the five days’ delay is due to late discovery of a hardware interface problem, and the remaining three days’ delay is due to being called to help the customer support staff for a production problem.”
    • At first, reporting this way wasn’t a comfortable thing to do. It forced us to get to the point quickly and not resort to obfuscation.
    • For many project team members, starting with the punch line can be disconcerting, but we have found that once they become accustomed to it, they truly enjoy the clarity of the message and the time saved in getting the point across.

      Try it, you’ll like it.

    • If I’m asked what the next most important quality is for a novelist, that’s easy too: focus — the ability to concentrate all your limited talents on whatever’s critical at the moment. Without that you can’t accomplish anything of value.
    • These thoughts all lead to a simple conclusion. When assessing your progress on producing things of real value (the best path to building a rewarding and well-rewarded life), consider your own capacity for hard focus. Most important accomplishments boil down to this single, often overlooked ability.

    • Revamped iPhone App — The big new feature here is Push notifications, which will allow you to get updated whenever you get a message without having to burn through SMS messages. The app also integrates a camera mode for taking photos, improved text entry (you can auto-save drafts and type in landscape mode), and improved performance. The app is currently pending approval in the app store, so we may have to wait a few more days to download it.

    • 补充一点,Hero现在价格虚高,要买也要等一段时间。如果要问我什么价格比较合适,我觉得3000-3500之间就可以出手了
    • 如果你是Linuxer,那么根本就不用搞什么安装器,装上sdk,直接用adb就可以安装apk程序。具体步骤请参考Android官方开发网。当然如果你不是使用的Ubuntu Linux,可能会在设备识别方面遇到一些困难,我会在近期写一下该方面的文章。
    • A:Hero买设备的时候自带2G的micro SD卡,该卡是class 4的规格。目前市面上常见的micro SD卡一般都是class 2和4的,class 6还是比较贵,我也没找到16GB的class 6卡。我目前使用的是8G的class 6卡,没有问题,我见过别人使用class 4的16G卡,也没有问题,所以至少Hero都能扩充成16G的容量。
    • 卡的速度对系统运行速度没有影响。也就是说,如果你的系统稍微有点卡,你换一个更高规格的卡,还是会有点卡,因为系统是运行在机内RAM里面的。但是,卡的速度对某些软件的运行速度会有很大影响,比如照片浏览,拍照,音乐等需要从SD卡中读写数据的程序,卡规格越高,速度越快。所以,建议是只要有米,卡的规格越高越好。
    • 实际上,你把这些不必要的功能关闭,把people和twitter相关插件从桌面清除(这些是你无法卸载的),那么Hero的运行速度就会大幅提升。如果你装一个taskiller软件,觉得有点卡时关几个不必要的进程,系统速度又会回升。所以对于Hero来说,稍微折腾一下,就不用担心系统慢的问题。如果你曾经忍受过WM的速度的话,那么Hero对你来说就是健步如飞了。
    • 我目前使用的频率是这样的:每天30分钟左右电话,wifi长期打开,check gmail,经常使用Calendar来安排工作,偶尔听听歌,偶尔浏览网页,偶尔用一些工具app的时间加起来一个小时左右,偶尔用Gtalk来聊聊天,总共可以坚持2天多。

    • The new format was designed to compete with Sony‘s Memory Stick format, which was released the previous year, featured MagicGate DRM, and was physically larger. It was mistakenly predicted that DRM features[3] would be widely used due to pressure from music and other media suppliers to prevent piracy.
    • In April 2006, the SDA released a detailed specification for the non-security related parts of the SD Memory Card standard. The organization also released specifications for the SDIO (Secure Digital Input Output) cards and the standard SD host controller. During the same year, specifications were finalized for the small form-factor microSD (formerly known as TransFlash) and SDHC, with capacities in excess of 2 GB and a minimum sustained read/write speed of 2.2 MB/s.
    • Note that maximum read speed and maximum write speed may be different. Maximum write speed typically is lower than maximum read speed. Some digital cameras require high-speed cards (write speed) to record video smoothly or capture multiple still photographs in rapid succession. This requires a certain sustained speed, or the video stops recording. For recording, a high maximum speed with a low sustained speed is no better than a low speed card. The 2.0 specification defines speeds up to 200x.
      • SD Cards and SDHC Cards have Speed Class Ratings defined by the SD Association. The SD Speed Class Ratings specify the following minimum write speeds based on “the best fragmented state where no memory unit is occupied”:[7]

        • Class 2: 2 MB/s – 13x
        • Class 4: 4 MB/s – 26x
        • Class 6: 6 MB/s – 40x

        SD and SDHC cards will often also advertise a maximum speed (such as 133x or 150x) in addition to this minimum Speed Class Rating. Important differences between the Speed Class and the traditional “X” speed ratings are; 1) the ability of the host device to query the SD card for the speed class and determine the best location to store data that meets the performance required, 2) class speed defines the minimum transfer speed. Even though the class ratings are defined by a governing body, like “X” speed ratings, class speed ratings are quoted by the manufacturers but unverified by any independent evaluation process.

    • SDHC (Secure Digital High Capacity, SD 2.0) is an extension of the SD standard which increases card’s storage capacity up to 32GB. SDHC cards share the same physical and electrical form factor as older (SD 1.x) cards, allowing SDHC-devices to support both newer SDHC cards and older SD-cards. To increase addressable storage, SDHC uses sector addressing instead of byte addressing in the previous SD standard. Byte addressing supported card capacities up to 2GB, whereas sector addressing can theoretically support capacities up to 2 TB (2048 GB). The current standard limits the maximum capacity of an SDHC card to 32 GB.[18] (It is expected that the SDHC specification will be revised in the future to allow card capacities greater than 32 GB.[19]) SDHC cards will not work in devices designed to the older SD 1.x specification. The SDHC trademark is licensed to ensure compatibility.[20]
