If you are working with large files, transferring them to S3 correctly might be an issue. To ensure data integrity you can send the MD5 hash of the file in Content-MD5 header.
After the transfer S3 compares the MD5 value of the transferred file with the value you provided. If they don’t match it returns an error. This is an easy and great way to ensure the file has been uploaded safe and sound.
To capitalize all words in a string you can use the function built-in the .NET framework ToTitleCase function in System.Globalization.TextInfo class
Here is a sample (taken from MSDN link below):
using System;
using System.Globalization;
public class Example
{
public static void Main()
{
string[] values = { "a tale of two cities", "gROWL to the rescue",
"inside the US government", "sports and MLB baseball",
"The Return of Sherlock Holmes", "UNICEF and children"};
TextInfo ti = CultureInfo.CurrentCulture.TextInfo;
foreach (var value in values)
Console.WriteLine("{0} --> {1}", value, ti.ToTitleCase(value));
}
}
// The example displays the following output:
// a tale of two cities --> A Tale Of Two Cities
// gROWL to the rescue --> Growl To The Rescue
// inside the US government --> Inside The US Government
// sports and MLB baseball --> Sports And MLB Baseball
// The Return of Sherlock Holmes --> The Return Of Sherlock Holmes
// UNICEF and children --> UNICEF And Children
In some cases you may want objects in a bucket be deleted automatically, for example for log files or surveillance footage you may want to keep only latest n days. You can run scripts to delete them manually but it can also be done by setting the expiration date on the bucket.
