Unable to extract trial version of Flex Builder 3

Recently, i wanted to try out to install Flex Builder 3 from Adobe website and after successfully downloaded the file i was unable to extract the files. It came out this error “Please select another location to extract the installer”.

I checked the hard drive and i have more than 10gb spaces in all my drives. I kept getting the error no matter what. I clear my Windows temp folders, tried in different OS such as XP and vista. I also tried to disable my firewall and remove my anti-virus software.None of them is working. I suspected that the downloaded file have been corrupted.

Oh yea. I forgot to mention that i have downloaded the file in my office. Apparently, the package i have downloaded have been scanned through proxy and Inter-scan anti-virus checked. That’s why the files get corrupted even i downloaded the Flex SDK packages. So, i went to my friend place and re-downloaded the files. All have been working fine without any errors.

So my conclusion is that, if you have the same error and tried the Adobe troubleshoot, and none of the steps above worked for you, you might try to re-download the packages from different computer or proxy, virus scan free.

PayPal AU Developer Program

Just went to Australia first PayPal developer program in Melbourne. The seminar was fantastic and interesting. The fact that only few certified PayPal developer around Australia and Asia Pacific quite shock me. According to their research, almost half of merchant websites customer will turn away from their website if PayPal is not supported as one of their payment methods. I supposed the Exam should be very hard or maybe not a lot of people ever heard of PayPal certification. For my own opinion, if your are frequently working with projects that involves with merchant or e-commerce getting PayPal certified will help you to gain credentials and trust at least. This is not some sort of certification that almost 6-7 out 10 have such as Microsoft Certificated when even 8 years old kids could get it.

PayPal actually came out several new products and APIs compare to last few years when i first time using their HTML based button for donation. Their even have widget that you can put on your website. Here are the website for United States : PayPal developer training and education and for the Australia version please refer to Australia PayPal : PayPal Australia and the AU Exam curriculum guide : PayPal Au Exam Curriculum Exam

The advance version is to improve user buying experience will be using Paypal Payflow Pro Gateway or Express Checkout where both allowed merchant to customise their own shopping cart(Paypal Payflow Pro Gateway) or using instant checkout experience that will redirect to PayPal website after buyer decided to place an order.

For more information about the exam.

From now on, i am officially PayPal Certified Developer.
