From Sutter’s Mill:

… The main trouble with Systems Hungarian comes from trying to embed information about a variable’s type into the variable’s name by prepending an encoded wart like the venerable sz, pach, ul, and their ilk. Although potentially helpful in a weakly-typed language like C, that’s known to be brittle and the prefixes tend to turn into lies as variable types morph during maintenance. The warting systems also don’t extend well to user-defined types and templates.

I am glad to learn that the Guru and I share similar views on this matter.

Some of my friends use iGoogle as a portal for handling daily office routines. They had been selling me the solution for a while. They were able to get me to give iGoogle a test drive a few weeks ago.

From Sutter’s Mill:

… we already had a nearly-complete C++0x internal working draft — most features that will be part of C++0x had already been “checked in.” Only a few were still waiting to become stable enough to vote in, including initializer lists, range-based for loops, and concepts.

Quote from Google C++ Style Guide:

We do not use C++ exceptions.

在極端狀況下, 我能夠想像在 no virtual function 或是 no templates 但仍能使用 STL 的環境寫 C++. 但完全禁止 user-defined classes/functions 以拋出 exception 的方式回報錯誤的環境呢? No, thanks. 即便有免費的食物與漂亮的辦公室, 這還是太折磨人了.

昨天在網上閒逛, 在樂多上看到篇名為 “Socket Programming in C 常犯的錯誤” 的短文. 這短文作者的動機很好, 指出常見到的錯誤並提供個人看法與可能較好的作法. 這樣的行為很值得鼓勵. 但極可惜的是, 結果卻是很不理想的. 容我說句重話, 如果是考試的話該文是得不到我的分數的.

很好笑的一段影片, 在 news.com 的 Microsoft 1, blogosphere 0 看到的.

首先我得說清楚我對 virtualization 這個題目沒有研究, 單純是個享福的使用者. 從很久 (8/9 年?) 以前在 MacOS 7.x (or 8.x?) 上用 Virtual PC 跑 Win95, 到近幾年的主要在 GNU/Linux 上用 QEMU 跑 Win2K 與 Minix 3.

一個不懂 virtualization 確切定義與技術細節的人, 一個使用過 Virtual PC, VMWare (player/workstation), QEMU, VirtaulBox 等 virtualization application 的人如我. 在使用過上述任何一種 virtualization application 後很容易就會知道, 把 virtual machine 開啟後首先會看到 POST (Power-on self-test) 畫面. 如果沒有其他如 boot image 等的設置, 接下來什麼也不會發生. 不會看到屬於某個 OS 的 shell 或是 desktop manager 的提示畫面, 使用者什麼事都做不了.

From the main page of MCSTL:

The Multi-Core Standard Template Library (MCSTL) is a parallel implementation of the standard C++ library. It makes use of multiple processors and/or multiple cores of a processor with shared memory. It blends in transparently and there is in principle no change necessary in the program itself.
