Do u pay attention to the Google’s logo today?

I was puzzled in my first sight. What’s this? Where’s google? I clicked the logo, and he told me a story, a story of Louis Braille.

Louis Braille was a French, who invented Braille. Aha! The name should come from his name. It’s a revolution for blind man to read.

A creative person, and a creative google.

“Happy birthday to Louis Braille.”

I’m busy and really tired recently. We’re developing Business Accounting& Settling System for Mobile corp. It will be released next week. Wish i can have a good Chinese New Year!

But I’m annoyed with the JVM in hpux now. Our java program can work well in windows, but crashed in hpux. Faint!

Aaah, the same program can work in another HP host. Its jdk is 1.4.2.05. The jdk which used in crashed host is 1.4.2.09. In hp site, it’s said that jdk 1.4.2.09 can work with HPUX 11.0, 11.15 and 11.23, not 11.11. Maybe it’s the reason. So we reinstalled jdk with version 1.4.2.05. To my sadness, it’s as before.

Sometimes it can work, sometimes it crashed, and sometimes it seemed to fall in dead loop. The cpu is busy, but nothing is done.

Give a simple test:

#!/bin/sh

while true
do
java -version
done
It crashed after executing for a while. I had no idea more. Maybe os patch is needed. Who know? We need to seek help from hp.

 

I can’t access the Dion Hinchcliffe’s Web 2.0 Blog site. I got the image from blog Chinese translation.

We met some problems for our 32-bit applications with memory in HP-UX recently. One is  the single process exceeded 1 G limit, the other is memory of CORBA server is too big while running for long time.

For the first problem, we can migrate application to 64-bit, or link using “-N”. It can change the executable file’s format to EXEC_MAGIC, which can support nearly 1.9GB.

And the second problem, while most unix dont return the free memory to the operating system, the application should be optimized. (“mapmalloc can return dynamic allocated memory to the OS, but the price is that memory allocation takes about five times longer”, said in “Modern Memory Management“) Something may be caused by dynamic allocation of STL, like vector. It’s better to use reserve for vector.

Some suggestions are also given in the article:

1. It is always wise to free objects you do not need, especially large ones as soon as possible, to minimize this footprint.

2. To avoid problems with memory fragmentation, try to avoid making many small memory allocations and instead replace them with one or two large allocations where possible.

“Microsoft acquires FolderShare.”  FolderShare can let u share ur files in different computers via Internet.

It’s useful for me. Like 若昔难得的Weblog’s said, “I can sync the directory of GreatNews, so both progress will be same now.” Oooh, it’s just what I want. And I think it will be easy to share LeLe’s photos with maggie now.

The only care is the security and privacy.
