ISO 8583 Tutorial article
Lately I’ve handle several financial project that allow me to understand bank and financial transaction better.
All (or most?) financial transaction is using ISO 8583 standard, which at first I thought is a complicated standard. But after learn and see how it implemented it’s not as complex as I thought.
In this post I will try to explain (based on my experience before I go deeper on the programming side.
I was really want to try LWUIT since several months ago. It’s look promising and it’s developed by SUN so I think every Java ME developer should take a look on this technology.
I’m also still new in LWUIT so there won’t be a lot that I can share for now, but at least I will show you a basic demonstration of how to use Form, Label, Command, and 3D Form transition (sound cool huh :p)
What you need:
I just realize that when sending to blackberry device when the email received on blackberry and the sender request delivered notification, it will automatically send delivered notification back to the sender.
And there’s no option to disable this.
Maybe it’s like a ‘feature’, but in my opinion it’s suck to cannot select whether we want to sent this delivered notification or not.
For spammer this could be good ‘feature’ since they will know which email still actively receiving their spam.
In my blackberry curve there’s only option to disable ‘read notification’, which located at message – options – email settings.
But read notification is not delivered notification, when I disable sending read notification still the blackberry sending delivered notification automatically.
This is sucks, anyone know how to solve this issue?
From my colleague I received an email but with unknown type : winmail.dat
He should send me office document.
I asked him to sent it again, he forwarded the email again but I still received winmail.dat in attachment.
After googling about this I found out that winmail.dat is generated by Outlook (I using thunderbird).
From About.com :
It’s Outlook’s fault, in a way. Or the recipient’s email client’s. If Outlook sends a message using the RTF format (which is not very common outside Outlook) for bold text and other text enhancements, it includes the formatting commands in the winmail.dat file. Receiving email clients that do not understand the code therein display it as a stale attachment. To make matters worse, Outlook may also pack other, regular file attachments in the winmail.dat file.
Fortunately, you can get rid of winmail.dat altogether by making sure Outlook does not even try to send mail using RTF.
And there’s also a way to disable this feature on Outlook. You can open it for more detail.
I would focus on how non-Outlook user can handle this format.
I know I can not ask all Outlook user who sent me attachment to turn off this feature.
So I search a program to open this content type “application/ms-tnef”.
I encounter this good console program : WMdecode
You just need to extract this. When running the program it’ll search winmail.dat in current folder and extract it.
The program working great although it just console application, no GUI.
Other tool I search is add on for Thunderbird.
I found : LookOut
This add on will automatically decode the winmail.dat
Also working great but it won’t decode winmail.dat in emails that you received before installing the add-on.
So I think it’ll only decode winmail.dat on new email received.
Microsoft planning to buy Yahoo for $44.6 billion. Until now Yahoo hasn’t give final answer it.
I’m wondering why do Microsoft want to buy Yahoo, is it for fighting Google?
Or Microsoft just want to kill one of his rival.
IM : Microsoft has Windows Live Messenger, Yahoo has Yahoo Messenger.
Search Engine : Microsoft has Live Search, Yahoo has it’s own search engine.
Email : Microsoft has Windows Live Hotmail, Yahoo has Yahoo Mail.
Let’s wait for Yahoo’s final answer.
And how will Google respond about this
Untuk yang bergelut di dunia Content Provider mungkin istilah VAS / VASP mungkin tidak asing lagi.
Buat yang ngerti tentang VAS ini maka mengutip dari Wikipedia.org :
A value-added service (VAS) is a telecommunications industry term for non-core services or, in short, all services beyond standard voice calls. On a conceptual level, value-added services add value to the standard service offering, spurring the subscriber to use their phone more and allowing the operator to drive up their ARPU. For mobile phones, while technologies like SMS, MMS and GPRS are usually considered value-added services, a distinction may also be made between standard (peer-to-peer) content and premium-charged content.
Value-added services are supplied either in-house by the mobile network operator value-added service provider (VASP). VASPs typically connect to the operator using protocols like Short message peer-to-peer protocolshort message service centre (SMSC) or, increasingly, to a messaging gateway that allows the operator to control and charge of the content better. themselves or by a third-party (SMPP), connecting either directly to the short message service centre (SMSC) or, increasingly, to a messaging gateway that allows the operator to control and charge of the content better.
Singkatnya para Content Provider (CP) membuat layanan dengan bekerja sama dengan operator dan berkomunikasi dengan protocol tertentu yang disepakati.
Dengan demikian maka CP dapat memberikan layanan kepada pengguna ponsel dan melakukan charging sesuai layanan tersebut.
