RVO and more 

Often I wonder about what is the best way to code my C++.  For example, read the first paragraph of the following (excellent) article:

http://cpp-next.com/archive/2009/08/want-speed-pass-by-value/

In that article, Dave Abrahams suggests that C++0x compliance is sufficient for proper return value optimization.  Note also in the comments about the requirement to create a variable in the function definition to guarantee RVO. However the fact remains that many projects are still stuck on VS 2008.  I have not seen any detailed comparison of which optimizations are supported by each compiler version.

Microsoft Visual Studio Express + OpenMP 

The generalities are clear, that you need a proper <omp.h>, vcomp.lib and vcompd.lib from the SDK, and that the SDK version must match your compiler version. 

VS 2005: http://blog.codekills.net/2007/09/20/openmp-and-visual-c++-the-free-way-%28sorta%29/

VS 2008: http://honya8bit.seesaa.net/article/163363596.html

VS 2010: http://www.ssidelnikov.ru/en/2011/05/openmp-visual-studio-2010-express/

VS 2012: OpenMP now supported by express version

Deepest Sender Fail 

Well, at least so far it is fail.  The web site is down.

Blogilo fail 

Well, I tried Blogilo.  Fail.

After some googling, I was able to retrieve the list of posts.  A bit of kung-fu was required to do this.  See this link:

https://ask.fedoraproject.org/en/question/9909/setting-a-blogger-account/

But in the end, it wasn't enough.  The post titles are retrieved but the contents are blank.  If I try to make a new post, when I hit "submit", it tells me it that the previous post, which is blank, was submitted (?!).

OMFG, Blogger sux 

Apparently all Blogger designs are fixed-width resolution.  It's like we're trapped in 1991.

The below will help.  It really works great.  Thanks Marco!!!

Life after Scribefire 

This sucks.  I used Scribefire for a long time because it is cross-platform, and I can run it directly from Firefox / Iceweasel.  But now it is broke without hope of repair.  RIP.

Windows
- Apparently "Windows Live Writer" is the way to go.  Now it's called "Windows Essentials".  You have to install the "Writer" tool.  I don't know what the other tools do.  Unfortunately WLW doesn’t have a simple way to add pre-formatted text.  The options seem to be to use courier font, use a code syntax highlighter plugin, or edit HTML.  Sigh.

Linux
- Stick with scribefire?
- Blogilo?
- Deepest sender?
