SMS Spoofing

There is a series of stories related to SMS Scam in Screeshots. If you would like to find out yourself whether you are unnecessary charged by our Telco, you should check your bill. I have not asked for a printed bill from Celcom, have to do so….

Read these two stories:

"Our parent company is worth RM3bil and we have a reputation to keep. Do you think we really need the extra cash from spoofing?"
- If you can earn more easily, why not?

Serial Peripheral Interface


I was asked to solve the interfacing E1 chip via SPI. First, try out with the parallel port in my PC, then, followed by the configurable processor. Both are running Linux. SPI uses only 4 I/O pins, thus, making it a perfect choice if you don’t want to waste your address mapping. The only setback is that it is a serial communication. Using the customized processor in FPGA, one single bit data transfer consumes 67.2 us. A read from or write to a register for 8-bit data takes about 1.68ms. Luckily, this is simply used for initial configuration and random monitoring purposes.

Niibe Yutaka & Debian


Had an opportunity to met Debian developer, Mr. Niibe Yutaka yesterday. This was the workshop organized by IEEE Computer Society, but more like a technical talk. Frankly, I was quite disappointed with the presentation. Perhaps, developer is not good in presentation but or maybe I expect for more technical insights. Basically, the talk focuses on advocating the “Free” software, the policies of Japanese government regarding Open Source and also the KuroBox/Pro. Some introduction to this little NAS box:


CPU: ARM9
Flash: NOR – for u-boot storage NAND – for linux kernel, rootfs
GPIO: 2 pin
Ethernet & USB Port


and yes Nibbe ported the debian GNU/Linux inside the box, showed us a simple demonstration on stepper motor and used the USB VGA adapter for X-Windows (sluggish). He even put the emacs on to the box. As I know, emacs is usually not included in embedded system, too big. Sound like a good education tool!

Anyone has try out debian distribution. I just Ubuntu is one of many derivative from Debian
