What Should We Teach New Software Developers? Why?
Posted on January 5th, 2010 at 0:29 by fr3@K

Would you trust someone who had not seen a patient for years to teach surgery? What would you think of a piano teacher who never touched the keyboard? A CS education must bring a student beyond the necessary book learning to a mastery of its application in complete systems and an appreciation of aesthetics in code.

這句話說得真好.

boost::decay documentation issue
Posted on January 4th, 2010 at 20:48 by fr3@K

前陣子看了 Hubert 的 一個 boost::exception 的例子, 猛然注意到自己不確定 boost::decay 的作用.

去看了它的 文件, 才發現文件不盡然正確… 已 submit 了一個 ticket 給 Boost, 希望早日修正.

Bit-fu

Did you know, for x is an integer, that -~x yields x + 1 and ~-x yields x - 1?

Another Good Interview Question in C++
Posted on January 2nd, 2010 at 17:10 by fr3@K

elleryq 的 這篇 blog post 談到的 ctor (換成 dtor 也一樣) 呼叫 virtual function 狀況 (或說是 problem) 會是很好的 C++ programmer 面試題目. 可在口試時用以窺探 interviewee 對 C++ object model 的了解.
(more…)

一看就知道 – 不 Thread-Safe 的 API
Posted on December 1st, 2009 at 13:37 by fr3@K

Very well put :)

當你發現回傳的是一個 char *，又沒有要求你特別 free 他，你是不是就該猜測他是回傳 function 內部的一個 static buffer 了呢？

Server side connection/session lingering
Posted on August 15th, 2009 at 18:39 by fr3@K

A great read on how to properly teardown a connection of synchronous protocols (e.g. HTTP) on the server side.

via: SO_LINGER is not the same as Apache’s “lingering close”.

STL Performance Boost in VS2010
Posted on June 27th, 2009 at 22:18 by fr3@K

幾個月前曾在一篇文字裡寫道: 正確的運用 Rvalue References, 有可能帶來可觀的 performance gain. 前幾天看到 Visual C++ Team Blog 新貼出對 STL (VS2010 vs. VS2008) 的 performance benchmark. 在一個程度上, 該篇文字可以說驗證了這個不只我一個人獨有的看法與對 C++0x 的期待.

Rvalue-References 帶來的 performance boost 或許比不上 Multi-Core STL 來得那麼 “方便”, 但絕對是你不會想要錯過的 low hanging fruit.

C++0x 的巨浪就要來了, 你準備好了嗎?
