The following window opens when you click on the .dmg file.

If you double-click on the folder icon in the window, you will have the option of selecting where Chrome should be insalled. The default location is the Applications folder where applications are normally stored. When you then double-click on the "Google Chrome" icon in the window, you will have the option of installing the software or running it from the disk image.

If you don't want to intall it, you can simply run it from the disk image, since it will then be "mounted" as a drive within the Finder

A webpage designer can choose to specify fonts and their size for a webpage or can rely on the user's browser to pick what is best for the user based on the browser's default settings. So some pages may be harder to read than others, if the webpage designer selected a font that is smaller than the default size.

You can do the same thing on a Mac system with Safari using the command and "+" key to zoom in or the command and "-" key to zoom out.

http(s)://username:password@server/resource.ext

Using the syntax of http:// or https:// followed by username:Password@ and then the URL, you could supply a username and password in the address bar. This could be useful in cases where you had to script access to a webpage or file download from a password protected directory on a website. Using this technique you could use a command in a batch file to gain access to the protected resource.

However, after version 6.0 of Internet Explorer, Microsoft disabled this capability. The rationale for disabling the capability is explained at Internet Explorer does not support user names and passwords in Web site addresses (HTTP or HTTPS URLs). Microsoft states there that the capability was disabled, because it could be used by a malicious person to mislead someone into thinking he was going to a trusted side when in actuality he would be directed to another site.

E.g., other information, besides a username and password, could be placed before the "@", for example someone could use http://www.wingtiptoys.com@example.com. A user might only notice the http://www.wingtiptoys.com in the address bar, whereas the URL would actually be taking the user to http://example.com. In this case, Internet Explorer 6 Service Pack 1 (SP1) and Internet Explorer 6 for Microsoft Windows Server 2003 only display "http://example.com" in the address bar. However, earlier versions of Internet Explorer display "http://www.wingtiptoys.com@example.com" in the address bar, but users might think they were going to www.wingtiptoys.com, whereas they would actually be taken to example.com.

If you want later versions of Internet Explorer to retain the behavior of prior versions, you can disable the new default behavior in Windows Explorer and Internet Explorer. To do so, create iexplore.exe and explorer.exe DWORD values in one of the following registry keys and set their value data to 0.

• For all users of the program, set the value in the following registry key:
  HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE
• For the current user of the program only, set the value in the following registry key:
  HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE

On the support webpage, Microsoft states that, if users attempt to use the previously supported syntax with later versions of Internet Explorer, users will see a webpage that has the title "Invalid syntax error". When I used the technique to try to access a protected file on a site using Internet Explorer 8.0 on a Windows 7 system, I received a message stating "Windows cannot find" followed by the URL and then "Check the spelling and try again."

The syntax of http://username:password@example.com/directory/filename.ext still worked on the same system with Firefox 3.6

Places.sqlite is used in Firefox 3 instead of the older bookmarks.html and history.dat files (the older files are left in the profile folder for backward compatibility).

I opened a places.sqlite file with SQLite. Note: Firefox must be closed when you try opening the file or you will get the error message "Error: database is locked".

C:\Users\Administrator\Downloads>sqlite3 C:\Users\Administrator\AppData\Roaming\
Mozilla\Firefox\Profiles\q3wdrb9w.default\places.sqlite
SQLite version 3.6.23
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite>

I then used .tables to see what tables were in it.

sqlite> .tables
moz_anno_attributes  moz_favicons         moz_keywords
moz_annos            moz_historyvisits    moz_places
moz_bookmarks        moz_inputhistory
moz_bookmarks_roots  moz_items_annos

The places.sqlite file contains the following tables:

• moz_anno_attributes - Annotation Attributes
• moz_annos - Annotations
• moz_bookmarks - Bookmarks
• moz_bookmarks_roots - Bookmark roots i.e. places, menu, toolbar, tags, unfiled
• moz_favicons - Favourite icons - including URL of icon
• moz_historyvisits - A history of the number of times a site has been visited
• moz_inputhistory - A history of URLS typed by the user
• moz_items_annos - Item annotations
• moz_keywords - Keywords
• moz_places - Places/Sites visited - referenced by moz_historyvisits

You can see what the columns are in a table using the .schema command, so I can use .schema moz_bookmarks for further information about the "bookmarks" table.

sqlite> .schema moz_bookmarks
CREATE TABLE moz_bookmarks (  id INTEGER PRIMARY KEY, type INTEGER, fk INTEGER D
EFAULT NULL, parent INTEGER, position INTEGER, title LONGVARCHAR, keyword_id INT
EGER, folder_type TEXT, dateAdded INTEGER, lastModified INTEGER);
CREATE INDEX moz_bookmarks_itemindex ON moz_bookmarks (fk, type);
CREATE INDEX moz_bookmarks_itemlastmodifiedindex ON moz_bookmarks (fk, lastModif
ied);
CREATE INDEX moz_bookmarks_parentindex ON moz_bookmarks (parent, position);
CREATE TRIGGER moz_bookmarks_beforedelete_v1_trigger BEFORE DELETE ON moz_bookma
rks FOR EACH ROW WHEN OLD.keyword_id NOT NULL BEGIN DELETE FROM moz_keywords WHE
RE id = OLD.keyword_id AND NOT EXISTS ( SELECT id FROM moz_bookmarks WHERE keywo
rd_id = OLD.keyword_id AND id <> OLD.id LIMIT 1 );END;

A diagram of the layout of the tables provides further information as does the The Places database.

I can see that there is a column named "title". So I can view the value for "title" for all entries in the table with select title from moz_bookmarks. Note: you may see a lot of what may appear to be extraneous bookmarks, i.e. webpages not bookmarked by the user. That's because you also see what you would see if you clicked on Bookmarks, Bookmarks Toolbar, Latest Headlines.

You can exit from sqlite with .exit, .quit, or Ctrl-C.

If you prefer a GUI to browse SQLite databases, you can use SQLite Database Browser, which can provide a graphical interface for browsing the databases on a Windows system.

To install the program, just unzip the files in the .zip file, once you've downloaded it, to the directory you want to use for it.

<?php
$IP = $HTTP_SERVER_VARS['REMOTE_ADDR'];
$FQDN = gethostbyaddr($HTTP_SERVER_VARS['REMOTE_ADDR']);
print ("<b>IP Address:</b> $IP<br>");
print ("<b>FQDN:</b> $FQDN<br>");
?>

I had to change the code to that shown below:

<?php
$IP = $_SERVER['REMOTE_ADDR'];
$FQDN = gethostbyaddr($_SERVER['REMOTE_ADDR']);
print ("<b>IP Address:</b> $IP<br>");
print ("<b>FQDN:</b> $FQDN<br>");
?>
