I first see japanese radish's flower. Suddenly stem of them grew taller and flowered with yellow tiny flower. Maybe they are all relatives so their flowers are very similar.

I sometimes feel wonder how splendid current smartphones are.
I grew up using old MS-DOS computer and old mainframe computer using at university about 1985- with 8.5 inch floppy disk. So compared these things, revolution of current IT technology is splendid.
My first computer(NEC VX21) were around 1MIPS, and my smartphone(LG G2 01f) is around 1000MIPS. When I was graduate student at 1989-1990, our lab introduced SUN sparkstation 2 and it was around 30MIPS. We used it for simulating our model of network and we are very excited this workstation's high spec.
So now I always carry 30 workstations I used to use !
Below are my history of computers I used (netbook,ipod,tablet,smartphone indicating "+")
- NEC VX21 (1987?-): V30/80286(8MHz),0.64MB(RAM),20MB(HD)
- Epson (1992?-)
- Fujitsu (1995?-)
- Sotec(notePC)(1998?- )
- Hitachi (2002-)
+ mouse compute: N450(1.66GHz),1GB(RAM),160GB(HD)
+ kindle 3 gen:Freescale i.MX353, ARM-11
+ iPod touch
- HP all in one 200: Core i 3, around 30000MIPS
+ Nexus 7: Snapdragon S4 pro(APQ8064)(1.5GHz,4core),2GB(RAM),16GB(Flash memory),GPU=Adreno 320,1920x1200(7inch)
+ LG L-01f: Snapdragon 800(2.3GHz,4core),2GB(RAM),32GB(Flash memory),1920x1080(5.2inch),battely=2900mAh,13.2M(camera)

At first, concept is very strange to me. My opinion is that I want to go to university that seems intersting. So goverment's definition is none of business.
And second is that attitude for education.
Every people has a right to study, so competition of test is nonsense to me. Test is one of a tool to know about their understanding are.
So thinking such things, I find omae's article and I feel relief..
