Windows 7: HOSTS File

When you type in a Web address such as www.example.com into a browser, the application contacts a DNS (Domain Name Services) server looks up the DNS name and translates it in to a numeric IP address. When Windows does a DNS lookup it first checks a file called HOSTS which is like a mini-DNS server before it checks the regular DNS server.  This file is a legacy technology from the past, but its left in the OS for backwards compatibility.

This file is a popular target of malware, which tries to use it redirect traffic from real sites to phishing sites to steal your personal information. The file is located in the following directory C:\WINDOWS\SYSTEM32\DRIVERS\ETC, and the file name is HOSTS with no file extension.

Note: Lines with pound signs (#) are comments.

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

Windows 7: Checking USB Device Power Usage

Did you know that there's preset limit on the available amount of power on a USB bus? If you have several USB devices plugged into your computer's USB ports, you need to be aware there is only a small amount power available for them.  Most computers have multiple what are known 'USB root hubs', and each hub can  deliver a maximum of 500 milliamps of power to attached devices. If the energy demands of the connected USB devices exceeds that limit, the USB bus can shutdown.

To check power draw of the USB devices connected to your computer:
  • In the Start menu search field, type: Device Manager and press the Enter key
  • In the Device Manager window, expand the node Universal Serial Bus controllers
  • Double-click on one of the USB Root Hub entries.
  • Click the Power tab. 

This tab displays a listing of attached USB devices, how much power they use and how much is available.  If you have more USB devices then you have available ports or power.  Consider buying a power USB hub that uses energy from the wall socket and not your computer's motherboard.

Software: Adobe Reader X

Over the last few years the Adobe Reader has been plagued with several security exploits. To address this problem, Adobe has released an upgrade called 'Reader X'. This update includes a sandbox design (called 'Protected Mode') to guard users from PDF attacks.

For example, some of the View menu options include extra large to small icons sizes (from 16x16 to 256x256 pixels), as well List, Details, Tiles, and content views.

Another way to achive the same results is by holding down the CTRL key, then use the scroll wheel on your mouse wheel to resize the icons or change the icon views by moving it up or down.

Firefox: Moving Your Cache to RAM (Performance Tip)

For a long time browsers have kept local copies of web page objects (such as HTML files, graphics, flash, and other files) on the hard drive. This allows the browser to access these files much more quickly if they're needed again without having to download them from the Internet.

Firefox has a setting that allows the browser's cache to be moved to RAM instead of the hard drive. Since RAM can be access much faster then the hard drive, this means that you can see much faster returns on any cache hits from your browser.

Warnings: 
  • This tip may cause problems with browser plug-ins.
  • Follow the advice of this tip at you're own risk, if implemented incorrectly it could disable the browser until its reversed.
  • Luanch Firefox
  • In the address bar type: about:config
  • Type browser.cache into the filter bar at the top.
  • Search for: browser.cache.disk.enable and set it to false (double-click it).
  • Search for: browser.cache.memory.enable and set it to true (double-click it).
  • Right-click anywhere, in the menu select New > Integer.
  • For the preference name, type: browser.cache.memory.capacity and press OK button.
  • In the next window, enter the size you want the cache in kilobytes (for example, typing 200000 would create a cache of 200,000 kilobytes or about 200 megabytes). A value of -1 forces Firefox to dynamically determine the cache size depending on the available system RAM.

Note: Since files are no longer stored on the disk, Firefox start-up can take longer. Also fewer objects are generally cached in RAM because of limited available system resources.

Follow the steps below to map a network drive (e.g. X:\ drive) to a SkyDrive folder.
  • Go to http://skydrive.live.com/ in your web browser.
  • Sign in to the Live.com site with your Windows Live ID.

  • Open Windows Explorer, in the left sidebar, right-click on Network, and select Map network drive...
  • Enter the following UNC: \\cdckda.docs.live.net@SSL\1234567890abcdef\Document
    • Notes:  
      • Replace highlight the UID in the UNC with the UID from step 3.
      • Replace “Documents” with the folder name with as appropriate.
  • Choose a drive letter, check Connect using different credentials, and press the Finish button
  • You will be prompted for your Windows Live ID.
Note: I am finding you connect and browse the files on the SkyDrive, but I am not finding you can upload to the drive from the Windows Explorer.  Although, I still find this a cool tip.

Microsoft's IE 9 Beta Offers Speed, Windows 7 Integration

eWeek reports: "Microsoft unveiled the beta version of Internet Explorer 9, the next release in its long-running browser franchise, during a high-profile Sept. 15 event in San Francisco. In addition to some key interface tweaks—the browser is now streamlined, with translucent elements designed to bring actual Web content front-and-center—IE 9 supposedly offers users greater speed and integration with Windows 7. Features include extensive support for HTML5, the ability to 'pin' Web pages to the taskbar and a 'Popular Sites' area that consolidates your most-visited pages in one place. Although Internet Explorer continues to hold a double-digit market share lead in the United States, it's faced a challenge in recent times from the likes of Mozilla Firefox and Google Chrome. By offering shiny new features, hand-in-hand with various security and privacy controls, Microsoft doubtlessly hopes that users potentially on the fence about other browsers will fall back into the IE camp. Time will tell, though, whether users and developers find IE 9 compelling to the exclusion of its competitors."

Check out eWeek's slide show for more information and screen shots of the new features.
