Suppose someone knows a folder name, and tries to list a folder on your site to find out what’s inside of it. Without any protection, it might display like this in the browser:

Now, let’s assume that you don’t want people snooping around in this folder, and trying to run the various PHP programs or investigate the contents of any text files.

The solution is to create an small index.php file that returns nothing, such as this:

// Silence is golden.  
// or display some message with an echo command: 
// echo "Cannot be displayed"; 

When someone puts the folder name without a filename after it, Apache will generally attempt to run the index.php of that directory.
You don’t need to change .htaccess or the CPANEL indexing options if you do this.

Today, with the popularity of GitHub, many people are using MarkDown files to create their documentation.
While there are plug-ins for Chrome I have yet to try, I found this cool site today:

Left side is where you paste the .md contents, right side is the formatted results:


Doesn’t that look a lot better than viewing it in Notepad?

To use it, just copy/paste the content of the “.md” markup file into the left side of StackEdit.IO and it formats it on the left, including the retrieval of the pictures. But note, any relative link might not work.

I sometime post my own code here so I can find an example I like in the future, rather than having to search the web. So there’s nothing extraordinary with the program below, just a good example of how to do SQL Server update commands using pypyodbc from Python.

It’s using a relation database (RDS) hosted on Amazon Cloud (AWS). The purpose of this program is as follows:
1) Read a CSV and get the domain name from column 2 (the CSV header was already removed)
2) Check to see if that domain-name exists in my table of domain names (SEOWebSite)
3) If it exists, update the seows_host_id to 4 (which is a foreign key to a table that specifies where the domain is hosted)
4) If it doesn’t exist, add it with some default values for various foreign keys.

import pypyodbc
import sys
print ("Python Version:" + sys.version)

connection = pypyodbc.connect('Driver={SQL Server};'
print ("Connected")
cursor = connection.cursor() 

# read each line of file
filenameContainingDomainNames = "c:/Users/nwalt/OneDrive/Documents/SEOMonitor/EBN Blogs Export_NoHeader.csv"
with open(filenameContainingDomainNames) as f:
	for line in f:
		fixLine = line.replace('\n', ' ').replace('\r', '')
		print ("===============================================")
		print (fixLine)
		columns = fixLine.split(",")
		domainName = columns[1]
		print ("domainName=" + domainName) 
			"SELECT seows_name FROM SEOWebSite WHERE seows_name = ?", [domainName])
		# gets the number of rows affected by the command executed
		row_count = cursor.rowcount
		print("number of matching rows: {}".format(row_count))
		if row_count == 0:
			print ("It Does Not Exist")
			SQLCommand = ("INSERT INTO SEOWebSite "
						 "(seows_userid, seows_name, seows_is_monetized, seows_is_pbn, seows_registrar_id, seows_host_id) "
						 "VALUES (?,?,?,?,?,?)")
			Values = [1,domainName,False,True,4,4] 
			print ("Data Stored:" + domainName)
			print ("Updating to EBN for domain=" + domainName)
			SQLCommand = "UPDATE SEOWebSite set seows_host_id = 4 where seows_name = ?"; 
			Values = [domainName] 
print ("Connection closed")

One annoying thing is that the rowCount seemed to be displayed as -1 or 0, one less than what I expected.
I didn’t need to fix it, but maybe next time would try this instead:

There can be many reasons for the python error “module not found”.

In my case, I had a laptop with 2.7 and 3.6 both installed.? ?My windows path contained the 2.7 release, but I was running the 3.6 release.? So when I ran from the command line by just typing in “python” it worked.? But when I tried in NotePad++, I was using Python 3.6 and getting the “module not found” error. I also needed to run “easy_install” in Python 3 on the modules that were missing (they were installed in Python 2.7 but not 3.6).

I was pleasantly surprised that in Windows 10, it’s now super easy to update the path.? They parse it for you and give you a special screen:

So I changed the three lines that started with C:\Python27 to C:\Python36.

To find the issue, I learned how to show the version of Python in the Python program itself.

import sys
print ("Python Version:" + sys.version)

For 3.6, the results are shown below:
