Andrew Ng machine learning course

Hi,

I was failing in the week 2 quiz - Machine learning course in Coursera.org, especially in one of the question which has multiple options (check boxes).

Which of the following are reasons for using feature scaling?

For the above question, I have attended the quiz many many times by selecting two items as answer (since it was check box option), i was keep failing the quiz.   

As a last choice, I submitted with one answer, I have completed the quiz.......  If you are also failing this question, try only one best answer you feel.   

Sorry, I forgot the answer :)

Thanks, 

ESRI basemaps loading maps diagonally

Hi,

Today,  I faced an issue in my esri javascript api 3.13 based simple web application.  

The basemaps were loading only the diagonal wise, all other blocks are blank.   In the chrome dev tools, every basemaps requests were success 200 response code.

The root cause was, esri.css version is different compared to the esri js version, like css was pointing to 3.12, esri js is pointing to 3.21.  

Thanks.,

When you install the ESRI BA data, sometime you will face "file not found error"..  But the file will be available in those locations.

To avoid this error, pls. reduce the no of folders in the path,  if there is more folders/sub-folders there will be issue.

Microsoft® Windows® Malicious Software Removal

MS is releasing a good malicious software removal tool with upgradation every month.  It is a good idea to download and run this tool every month, even though we have Antivirus/Windows Defender.

h) once the scan is done, just turn on your antivirus.  ( windows defender will go off automatically).

Could not start ArcSDE - Check Network, $SDEHOME disk, DBMS settings....




Today, I created multiple ArcSDE service instances and few services deletion.   When I started one of the service, it has thrown an error "could not start ArcSDE..." for the command sdemon -o start -i esri_sde.  

Then I tried with sdemon -o start -i esri_sde -H c:\arcgis\arcsde\ora10gexe\.  It started properly. I am not sure whether the deletion of the service instance esri_sde has not done properly...
