Wireless Charger

About two years ago, I imagine one day people will make a wireless charger and wireless power supply. This discourse I was talking with my friends in  'coffee shop' chat that we often do at lunch or in the court of the mosque before prayers. My friends just smiled and gave a brief comment. Perhaps they already understand it because I often talk about the 'crazy' ideas with a half-joke.

IT Human Resources

Indonesia is a country that has a large enough population. Thus this country rich in human resource potential in all areas. No exception of human resources in the field of information technology. If we look, how many high schools have faculties, departments, or even the specialized high schools for the field of IT. So many graduates from these colleges every year, even every semester. Starting from a diploma, undergraduate, master's, and Doctoral degrees can be obtained in the country. Not to mention the certification of IT expertise is widely available.

Whose fingerprint? (Sidik Jari Siapa yang Punya?)

Still remember the songs that have the words' ‘Nona manis siapa yang punya?’ If it was, easy answer, there is in the song itself. But if a crime occurs murder or robbery, the police officer was busy looking for the perpetrator's fingerprints left at the scene. Having met a few fingerprints and the question as the title above, the answer would be hard to find.

To match fingerprints found at the scene, the police would have to have a fingerprint database population. Did the police have it? I am sure, only a small portion. Not all residents enrolled in the police fingerprinted. So there is a possibility if the fingerprints found at the scene, the police officer had no comparison data.
How is the solution? Let you use your own thought.
