How to save video from Internet Explorer

How to save video from Internet Explorer Here I am going to share an experience with you, where I was required to get the video file that I was playing in Internet explorer out of Temporary directory and save it to some permanent disk folder. Note: It is far better if you use video download tools with the web browser. Internet Explorer Version: 7.0.6xxx [Open Internet Explorer – Help – About Internet Explorer] Operating System: Windows Vista I was not playing file from you tube [I do not see any tmp file while watching video from youtube.] I found the file in following directory: C:\Users\<UserName>\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low [ Although the directory is not visible in my computer system, so I directly put it in address bar/location bar in windows explorer. ] File name was fla3870.tmp [May be in your system It will be by different name] You have to find the video file by trick technique for example: 1.

error 18 at 0 depth lookup: self signed certificate

-
I was trying to test SSL connection between MySQL client and server. For that I created SSL certificate and keys by following the MySQL documentation at: Creating SSL Certificates and Keys Using openssl After finishing up all the commands when I verify the certificates by using: openssl verify -CAfile ca.pem server-cert.pem client-cert.pem I got the following output: error 18 at 0 depth lookup : self signed certificate error server-cert.pem: verification failed client-cert.pem: OK  Reason : The Common Name value used for the server and client certificates/keys must each differ from the Common Name value used for the CA certificate. Otherwise, the certificate and key files will not work for servers compiled using OpenSSL. Solution : When OpenSSL prompts you for the Common Name for each certificate, use different names. Common Name (e.g. server FQDN or YOUR name) []: I used values as follows: CA Cert:  ssl-ca-cert Server Cert: ssl-ca-server-cert Client Cert:  ssl-c

How to check fragmentation in MySQL tables

-
MySQL tables, including MyISAM and InnoDB, two of the most common types, experience fragmentation as data is inserted, updated and deleted randomly. Fragmentation can leave large holes in your table, blocks which must be read when scanning the table. Optimizing your table can therefore make full table scans and range scans more efficient. We will mention how to check fragmentation in MySQL tables using SQL queries. USE < put_your_dbname_here > SELECT TABLE_NAME, CONCAT(ROUND(( data_length + index_length ) / ( 1024 * 1024 ), 2), 'M') TOTAL_SIZE, CONCAT(ROUND(( DATA_FREE ) / ( 1024 * 1024 ), 2), 'M') DATA_FREE FROM information_schema.TABLES where table_schema = database() and ROUND(( DATA_FREE ) / ( 1024 * 1024 ), 2) > 0.00 ORDER BY DATA_FREE DESC; SELECT TABLE_NAME, ROUND(((Data_length - (TABLE_ROWS * Avg_row_length))/Data_length) * 100, 2) FRAG_Percent FROM information_schema.TABLES where table_schema = database() and TABLE_ROWS > 0
