I didn't notice that after I have upgrade the Skype to a later version (22.214.171.124) on my OS X, I can't Skypeout again. Not just Skypeout, I can't make skype call to my friend online.
I thought is the new Skype problem, but I have deleted the older version from my hard disk, so I upgrade to the beta version (1.4), and is not working too.
When skypeout it just keep show connecting, but I can't hang up the call.
When skype to online friends, it shows 'Playback error'.
My friend told me could be the sound setting, but all my application is working ok except the Skype, but I remember I install a soundflower software which can redirect the audio to another application, I though I can use it as my skype recorder.
After i uninstall the soundflower using OS X Package Manager, the skype is working again, including skypeout, seems like skype confuse with sunflower.
Soundflower is an open source software.

All these database are installed and used in our development environment, I have installed most of it by myself many years ago, mostly old version which are outdated, eg. Informix 5(?), Oracle 8.
Install Oracle 8 on Linux operating system is not an easy task, you need to patch the system, at the middle of the installation process. I think Oracle people don't write good installer on Linux, may be they don't have good software people who familiar with Linux development, I hope they have improve by now.
Normally programmer focus on programming, we left SQL queries to the database administrator. We don't know much about database optimization, it need a professional to do it. That is the ideal case, normally we have to play both roles.
I know how to compile postgresql and mysql database, does it consider a special skills? I even do software packaging for postgresql on Linux and Solaris. I know some other database like Cloudscape, if you have forgotten, it is a embedded database purely written in java, and is open source. Cloudscape can store a java object as a data field, eg. a java method (function). Cloudscape source code has pass to apache, will be Derby next time.
I know another database(?) call netisam (from Sun, and no more supported by Sun), I bet not one heard it before, even if you know about it, you should have erase it from you memory, because netisam don't support JDBC, ODBC, even SQL queries! (I put a question mark after the database) and no more supported by Sun. Then how it works? If you have worked on Informix ESQL/C before, you should know, netisam is just an embedded database.
The worst thing about netisam is, I don't find a open source replacement for it!

Jason from Planet Malaysia include my blog into the website, but he ask me do I have another feed? The atom feed from blogger doesn’t display any content in PlanetMy. Jason didn’t told me what is the difference between my feed and the others. May be PlanetMy don’t know how to handle the different format between atom and RSS.
I suddenly recall, I have another feed from feedburner. The display seems to look better now. The atom feed just display one line in PlanetMY, without any content:
BLUE - People: Antero Taivalsaari
The feedburder’s feed display the title and content:
FuYiChin - People: Antero Taivalsaari
Antero Taivalsaari started the KVM (K Virtual Machine) project while working in Sun Lab …
RSS, Atom, And The Syndication Standards Dance
People still don’t get use of online technology?
I though I am going to work on Palm programming, but didn’t. I went for the movie ‘King Kong’ (2005, by Peter Jackson), is hard to get movie tickets from Mid-Valley and KLCC cinemas, is a long queue during holiday seasons.
directed by Peter Jackson, 2005. Is the re-make of the 1933 'King Kong' and not the 1975.
Finally get the ticket from Amcorp Mall cinema, you don’t need to queue up for a ticket, and they don’t use computerize ticketing system like GSC or TGV, they use paper and pen to mark the seats and movie tickets.
Someone should sell a ticketing system to them, but after I thought over again, if the current system works for them, they do not need another system, until their business expanded.
The second question in my mind, since there is online booking system available, like cinemaonline, why people still queue up for hours to buy movie tickets? Is just wasting time queue up at the ticket counter there. The truth is I don’t use online ticketing system too, because normally I don’t go for a movie during peak season.
I suspect a lot of people have book the tickets, but did not turn up and collect the tickets. I hope there is a better system, easier to use, can buy ticket through PDA or mobiles, cut down the long queue. For those people who are not familiar with computerize system, they can stick with the traditional (queue) system.
Singapore Golden Village Multiplexes, use Red Hat Enterprise Linux system as their booking system (replace the earlier Windows Server), may be the volume of their online booking is bigger.

After trying very hard on setting up palm development on windows cygwin environment, but fail. Finally I get it running on OS X environment.
You need the prc-tools to compile the palmos program, prc-tools are just gcc cross-compiler for palmos platform, sometimes we just name it as toolchain. prc-tools is available in sourceforge, but there is no os x binaries download. I found some download link for prctools-osx, but is not valid anymore.
Finally I get a copy of prc-tools from here (it doesn't look like an apple site?), package by Zenonez.com, it should be available in Apple ADC too. According to the announcement, Metrowerks has drop m68k palm support in CodeWarrior, so Zenonez.com continue working on the prc-tools on os x.
Zenonez.com has package everything (including the Palm SDK) together, integrated well with Xcode (OS X Development Tools). I follow the instruction from Zenonez.com to compile MacPalm hello world program, it works. But I can't locate where is the m68k-palmos-gcc compiler. Is 3am after I finish, I should have gone to sleep 2 hours ago.
