[Solve] No APN specified on the device

0

A few weeks ago, I got updated Android 4.4.2 for Nexus 4. After I upgraded my phone.

I have noticed “No APN specified on the device” display on bottom of the screen when I turned mobile data on.

Once,this message appeared

- Battery was draining very fast.

- My Nexus 4 was hot and consumed high CPU all time.

So, my solution is reset APN configuration to default by these following steps.

  • Settings> Wireless & Networks > Mobile Networks > Access Point Names > Options at  the top right and then “Reset to default”

Installing Google Drive on Windows 8 and python26.dll (error code 5)

5

Today, I just try to install Google Drive on windows 8. And I found tricky for complete installation with Google Drive.

First, I start Google Drive by this link. https://drive.google.com/

But It seems like download or starting for install is not working.

So I choose alternative way which Google gives to download googledrivesync.exe and install on PC.

But when I double click on googledrivesync.exe file, It doesn’t response anything.

I have to choose “run as administrator”.

Now, It’s working and install complete.

But I got “Error loading Python DLL: C:\Users\AppData\Local\Temp\_MEI82962\python26.dll (error code 5)” and Google Drive can’t  start running.

To resolve this problem, you have to copy python26.dll and leave this file in C:\Program Files (x86)\Google\Drive (or somewhere on Google Drive path)

Download :  python26

Something like this photo below.

Enjoy with Google Drive on Windows 8

 

 

Run as root with single line command without prompt on Linux

One of my failure, I tried to execute single command to server with SSH but I found when I executed as root.

It would be prompt to ask me about password.  So my command couldn’t complete.

So I found this solution should be something like this below.

echo [YourPassword] > auto_password
su - -c "[YourCommand]" < auto_password

The first line,It will echo your password to auto_password file.

The second, this is important you can execute you command without prompt. Your password will be passed by auto_password file.

Last, This command will be remove your auto_password.

I hope this will help Linux novice like me.
