I used mediatomb as DLNA server for Sony Play Station 3.
Now I bought Play Station 4, at first I could not play same settings of mediatomb.

1. download Media Player for Play Station 4[Free].
2. change settings of mediatomb as below.

<map from="mpeg" to="video/mpeg"/>
<map from="vob" to="video/mpeg"/>
<map from="vro" to="video/mpeg"/>
- <map from="m2ts" to="video/avc"/>
+ <map from="m2ts" to="video/mpeg"/>
<map from="mts" to="video/avc"/>
<map from="asf" to="video/x-ms-asf"/>
<map from="asx" to="video/x-ms-asf"/>

I think Play Station 4 does not support "video/avc", it must be "video/mpeg".

I put my configuration file(config.xml) at

[DMM Eikaiwa] How long does teacher teach English?

1. How many registered teachers in DMM Eikaiwa?

Currently Max teacher ID is 16360(as is Dec/2016). But registered teacher is only 5383(orange line). This number is stable around 5000 from April/2016. DMM Eikaiwa tried to hire new teacher(so increase max ID number), but many teacher resigned.

2. How long does teacher teach English?

1 year(RED bar) is decreasing. Some teacher is step up to 2 years(Orange bar). But < 1 year(Blue bar)is not shift to 1 year(maybe resign before 1 year). So 1 year is decreasing, I think.

And if this trend(resign level high) continues, teacher skill level may be down because less than one year teacher will be increased.

[Android] "android stack corruption detectedadb logcat"

When I logged some debug information, logcat was stopped. Never get new logcat message from Android.

One reason of this issue is included "BINARY" strings in logcat buffer.

So you need clear logcat buffer and you can get newer message.

adb logcat -c

and

adb logcat

I hope Google fix this "BINARY" string issue in adb logcat.
