Windows console applications. Multimedia

Operating systems : Windows

MPlayer : FFmpeg

Media players appeared long ago, but their heyday began with the mass spread of personal computers powerful enough to play video files. This coincided with the mass spread of operating systems and other software with graphical user interface. However, a program with a graphical user interface is dualistic in its nature: there is a code responsible for graphical user interface, for the appearance and there is a code - for performing the task the given application has been created for in the first place. Both code complexes consume system resources, their response time to user actions makes up certain amount of waiting time. And in cases or concepts when appearance is taken as less important - less important to the point of sparing or almost sparing to employ it - console applications, among others, appear. Moreover, the segmentation of the GUI and of the engine makes it easier to change the graphical user interface or perform complex automated operations.

The scheme is implemented for media players for Windows as well. MPlayer, for instance, in its usual form is a console application, starting up quickly, having fast response to user actions, consuming system resources almost entirely for its immediate task. And on this basis if desired, one or another graphical interface may be added for creating, all in all, a new application.

HTML centering

 

Centering the whole content of a web page in the viewable area of a browser by pure HTML - no CSS. A box to keep the content of the page is HTML centered horizontally and vertically - [ Open demo page ] HTML. Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>HTML centering</title> <meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"> </head> <body bgcolor="#ffffff"> <table width="100%" height="100%" bgcolor="#a3ddc4"> <tr> <td align="center"> <table width="800" height="500" bgcolor="#ff6f6f"> <tr> <td>&nbsp;</td> </tr> </table> </td> </tr> </table> </body> </html> The outer HTML table makes the whole web browser viewable area, except margins, a HTML table and the whole area of this HTML table - a HTML table cell. The cell of the outer HTML table inherits the default value for valign attribute from its parent table row. And this row in its turn inherits the default value for valign attribute from the outer HTML table tbody - even if tbody tag is not used. And that value is middle. So a block of content inside the cell of the outer HTML table is centered vertically in web browser viewable are. Align="center" of the outer HTML table cell makes a block of content inside it centered horizontally in web browser viewable are. The inner table, the one inside of the outer HTML table cell makes up a box of a given size. Or there may be no set height or no set width or both. Then the size of the box is to adjust to accommodate the content, whatever its dimensions are. If the width or height or both of the box results to be larger than web browser viewable area, then it still ends up to be centered. Since HTML centering is the oldest method to center content horizontally and vertically, it works well not just in older web browsers, but in ones that can be described as downright ancient. Like adding one more HTML tag ( <center></center> ) around the outer table makes it funcion as deep as Internet Explorer 3 : [ Open demo page ] Download Internet Explorer 3: a pack, containing 3.0, 4.01, 5.01, 5.5, 6.0 versions of Internet Explorer HTML.

Imapsync. IMAP migration

 

Migrating an IMAP account from one IMAP server to another [ 1 ] in Linux [ 2 ], command line: imapsync --host1 imap.this.com --user1 email@example.com --passfile1 /home/user/imap/passwordfile1 --ssl1 --host2 imap.another.com --user2 email@example.com --passfile2 /home/user/imap/passwordfile2 --ssl2 --skipsize --allowsizemismatch - There is a web site (example.com) and an email box (email@example.com) hosted at a web hosting company. The IMAP server: imap.this.com. The IMAP server supports SSL. - The example.com web site is to be transfered to another web hosting company. So is the email@example.com box with all its contents and keeping its folders structure. The IMAP server of another web hosting company: imap.another.com. The IMAP server supports SSL. 1. Set up an email box named email@example.com and a password to it on the server of the web hosting company the email@example.com mailbox is to be transfered to - from the previous web hosting company. 2. Create two text files in /home/user/imap/: passwordfile1 with the password for the mailbox on the first IMAP server and passwordfile2 with the password for the mailbox on the second IMAP server. 3. chmod 600 /home/user/imap/passwordfile1 4. chmod 600 /home/user/imap/passwordfile2 5. Install imapsync 6. Run imapsync Imapsync transfers a mailbox - keeping its folders structure - from imap.this.com to imap.another.com. SSL is used to enable encryption and passwords are saved to protected files (chmod 600). Migration between two email service boxes may happen to require to make use of more imapsync options [ 3 ]. Like transfering contents of one Gmail.com box to another demands to have "--port1" and "--port2" specified: imapsync --host1 imap.gmail.com --port1 993 --user1 email1@gmail.com --passfile1 /home/user/imap/passwordfile1 --ssl1 --host2 imap.gmail.com --port2 993 --user2 email2@gmail.com --passfile2 /home/user/imap/passwordfile2 --ssl2 --skipsize --allowsizemismatch [ 1 ] A simple and common case: contents of one email box are transfered to another, empty mailbox.
