auto mount a windows folder share on debian startup for development purpose

Auto mount a windows folder share on debian startup could be your honey if you run into this situation:
1. run linux as a website server development environment
2. most of your tools with good ui only run under windows
To bridge this gap, you want to have linux access to your windows share, and this is how to do it:
work on the windows:

  1. create a user “linuxweb” with the password “1y1cc1″ (please use your own values in your situation)
  2. share your work folder as “workproject” and make sure the user “linuxweb” you created have all the permission

work on the linux:

  1. create the mount point by these commands:
    mkdir /website
    mkdir /website/winworkproject
  2. setup auto mount on debian boot, run:
    pico /etc/rc.local
    and add this line to the file:
    mount -t cifs //192.168.1.99/workproject -o username=linuxweb,password=1y1cc1,uid=www-data,gid=www-data /website/winworkproject

One problem:
There is one problem I run into during this adventure: I initially tried to auto mount the share by fstab:
//192.168.1.99/workproject /website/winworkproject cifs username=linuxweb,password=1y1cc1,uid=www-data,gid=www-data 0 0
but got an error saying:
CIFS VFS: cifs_mount failed w/return code = -112
I have no clue what code -112 is, then I have to do it by rc.local and it looks work well. Please leave a comment below if you know what code -112 is, thanks!

sendmail is being slow on linux

sendmail is very easy to install and use with php on linux. But it could be slow by default configuration. The reason which I ran into is because the server doesn’t configured with a qualified host name and it keeps retrying. To fix the issue:
open
/etc/hosts
and set the ip for your domain like this:
200.100.100.200 youdomain.com

I haven’t got the whole picture of this, but this quick fix does work. Hope it could also help you if you are demand a quick solution.

How to use:

  1. Select the video file you want to convert to gif.
  2. And then choose the start time and end time in the video that you want to convert to the gif. You can use the text box to fine tune the time for the region of the video.
  3. Change the fps value to specify how many frames a second that you want to have your gif to play at. The smaller the fps value is, the slower the animation will appear.
  4. If you don’t want all the frames, select from “use every x frames” drop down list to skip a few frames. Be aware that if you skip more frames, the faster the animation will appear. You’d better reduce the fps value to compensate for the frames you skipped here.
  5. Finally, use the drag bar to resize and set for the size of the final gif.
  6. Click the “Start” button to start create the gif, the gif will be auto named with the same name as your input video file and will be created in the same directory. If the conversion success, you can click on the file name to open the folder.

Cautious: The more frames you want to pack into the gif and the bigger size you specified for the gif, the longer time it will take to create the gif. So be prepared to wait for several minutes or even tens of minutes if this is your case.

Features:

  • drag and drop to specify the beginning and end of the video portion you want to convert to the gif
  • be able to fine tune the start and end of the video with text box
  • be able to specify the fps value that gif will be played back
  • be able to skip a few frames if not all that is useful
  • resize to the desired size for gif
  • preview of the frames
  • auto create the name of the gif file

Solution to missing mkstemp when you are compiling under mingw

I googled around, doesn’t find a perfect solution. But I do come across 2 files on apple website, they actually implement the missing functions while dealing with the code ported to mingw.
http://www.opensource.apple.com/source/Git/Git-17/src/git/compat/mingw.h
http://www.opensource.apple.com/source/Git/Git-17/src/git/compat/mingw.c

For my scenario, I simply created a compiler based branch:
#if defined(__MINGW32__)

int mkstemp(char *template)
{
char *filename = mktemp(template);
if (filename == NULL)
return -1;
return open(filename, O_RDWR | O_CREAT, 0600);
}

#endif

I also downloaded and attached here in case could be useful later: mingw.zip
