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.

New mind set

一直以來 exception handling 與 exception safety 就是 C++ 最重要的課題之一. 正確的 exception handling 真的不是一件跟吃蛋糕一樣容易的事.

但, 它是否一定如此困難, 以致於 只有語言專家才能搞得定? 我認為這與事實相去甚遠.

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.

GION is a project I recently created as a part of my effort towards cleaning-up some of the not-so-pretty and strengthening exception safety of the project code base at work.

It’s released under one of the most permissive FOSS licenses I know of, MIT license, in hope, would help others to write better C++ more easily.

Feedback welcomed.

在幾個月前還沒確定落腳處時, 經過一個月左右的奔波面談, 幸運地拿到幾個 offer letter. 其中一個是玄力科技.

玄力是一間今年初剛創立的 startup 科技公司, 致力於研發利基型的創新資安產品. 我與玄力的幾位 key person 談過, 他們很 nice, 也都很有抱負很有想法. 其中的 founder 更是有在美國成功的 startup 經驗. 制度面上的設置是 startup 中少見的完善. 在台大育成中心的小辦公室裏面, 我看到了理想衝撞出來的火花, 只是有了老婆卻沒存款的我沒條件也沒膽量在這個時候再去 startup 拼一次.

你是想找個 fresh start 的 C++/Linux 人嗎? 可以去聊聊天, 說不定你也會喜歡玄力.

玄力徵才 on OSSF and 104.

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.

For those of you using Delicious Bookmarks with Firefox, beware of that the latest version of the add-on (2.0.58) may break your tab navigation functionality.

Symptoms:

1. CTRL+PG_DOWN (and CTRL+PG_UP) behaved very funny. Instead of setting focus on the next tab, it sets focus on the tab next to the next tab. If I had exactly two tabs, C+PD/PU would always set focus on the tab that currently has the focus, i.e. nothing really happens.
2. Opening new tabs at the wrong tab order. Always to the right of the last tab.
3. Closing tabs sets focus on the wrong tab. Always on the first tab.

I am running FF 2.0.0.14 on Ubuntu Gutsy with roughly 30 add-ons enabled. I am way too lazy trying finding out if this issue only happens when certain add-ons are installed/enabled. Unless someone, who is serious in tracking this issue, needs me doing so.

Reverting Delicious Bookmarks to 1.5.44 (avaiable here) resolved the problem.

The last two symptoms described here might have something to do with Tab Mix Plus (I am using 0.3.6). I’ve reported this issue in a review on Firefox Add-ons.
