I remember listening to the opening of Orson Wells’ radio adaptation of War of the Worlds, but unfathomably do not remember listening to the remainder. So, when I picked up the book by the unrelated Herbert George (or simply “HG”), most of it was still new to me.

I was surprised by the opening chapter’s “humanitarian” view of the Martians, that they treated the pestilence of humans with the same amount of thought that we would regard a termite mound or an ant colony — travel to our planet in their case was a matter of survival, not ambition or malevolence. Even as the humans of southern England were being systematically eradicated, it was not a difficult stretch to liken the invasion of the Americas by the white man (and the subsequent eradication of the American Indians) as a less “humane” treatment than that by the Martians. No matter how heartless they were, at least they used us as food! OK, so the heat ray was a bit of a waste of resources, a point against…

Speaking of technology, the infamous flying machines didn’t take as much a part in the written version of the story as I either remembered or expected, perhaps license being taken by some other adaptation. Despite all their societal, physiological and mechanical advances, the fact and method of the invaders’ demise was predictable and inevitable, anticipated almost from the moment I began reading.

War of the Worlds was a fun read — in spite of the frequent inhumane acts, the mass disorganization of our supposedly superior race, and the occasional limb or appendage being violently removed from use!

Here’s an interesting submission from a reader:

My Dad got a new computer last week which he had me help set up and configure. One of the things I noticed was that the 40GB hard drive he ordered didn’t seem to be as large as advertised. I checked the drive by accessing Properties in My Computer; his hard disk showed a total capacity of somewhere around 34 GB. When we checked the Hardware tab and looked at the properties of his hard disk there, it showed something like 3 partitions — one of which totaled to about 38 gigabytes. We called the computer maker’s technical support department to find out why the 40GB drive never seemed to show a capacity of 40 GB and the answer we got was a rather vague: “Some of the disk space is taken up with system files which you can never see in Windows so you’ll never see the whole 40 gig as being available.” The person sounded like they were reading off a FAQ screen, and trying to clarify the issue didn’t get anything more useful out of them. What’s really going on?

There are several factors at work here:

Formatting Allocation

While you can rarely purchase an unformatted hard drive these days, many drive manufacturers continue to advertise the unformatted capacity of their products, not the more sensible usable formatted capacity. The low-level formatting usually completed by the manufacturer records thousands or millions of pieces of data throughout the drive to mark positions of tracks and sectors — roughly analogous to searching for words in a book by chapter and page. High-level formatting accomplishes a similar task but for specific file systems — such as FAT16 (DOS), FAT32 (Windows 95/98), NTFS (Windows NT), UFS (Unix), MFS and HFS (Apple Macintosh), and others — and creates space for storing special file attributes such as hidden, read-only, and directory statuses.

Not surprisingly, all that formatting can take up about 5% of your unformatted disk capacity. Your 40GB drive is now 38GB.

Extra Partitions

Most name-brand computer manufacturers — including Dell, HP, and IBM — cut costs by sending out computers with no setup disks, CDs, or manuals. The installation disks for the bundled software — the operating system; the free software of typical giveaways like Quicken, MS Money, and MS Works; the proprietary drivers to make the CD, sound card, and printers function properly — are all stored on a special, usually invisible partition (a separate data storage area) on the hard drive which usually boots only the first time you turn on the computer. This partition is not normally compatible with mainstream operating systems, and cannot be detected by them without a special utility.

When the computer is first booted up when unpacked from its shipping box, the installation programs for the software packages are then either executed directly from the phantom partition or copied over to the hard disk for later installation. This special partition is very rarely removed during the installation process and usually remains, often taking up several gigabytes of disk space. This is really a great feature because the phantom partition can often be used to restore a completely messed-up system to factory defaults by inserting a special restoration diskette disk or CD available from the computer manufacturer’s support department.

Thus, your previously 38GB drive is now sized between 34 and 36 gig. Keep in mind that this factor only applies to primary (or first-position) drives purchased at the time of manufacture of a major brand-name computer; extra secondary drives purchased to expand your system’s storage capacity do not contain the phantom partitions.

Gigabytes vs Gibibytes

The least known and potentially most insidious factor stems from less-than-honest (or hopefully just plain ignorant) marketing departments. If you examine the fine print of many advertisements, whether printed or broadcast, you will often see printed a definition of megabyte (MB) as 1,000 kilobytes (KB), or a gigabyte (GB) as 1,000 megabytes — this conforms with the standard metric system and is accurate.

However, the disk usage displayed in the operating system’s user interface is usually calculated using powers of two; a kibibyte (KiB) is actually 1,024 bytes, a mebibyte (MiB) is 1,024 kibibytes, and so on. The difference in  decreases conceptual storage space by 2.4%.

If all of the above factors apply to a particular 40GB drive in the extreme, it could show only 32GB of free space! And that’s why your 40GB drive may not be a 40GB drive after all…

Many websites that have been designed to continuously monitor specific events use an automatic refresh to ensure the most recent data is visible. This is usually accomplished either through a REFRESH META tag in the HTML header, or by using JavaScript to set an elapsed time after which the page is refreshed. Other more complicated and sometimes less desirable methods use Flash or Java applets to continuously access data directly from the database.

An often annoying side effect is that Microsoft Internet Explorer (at least on Windows platforms) makes a clicking sound at every refresh, the same sound made when clicking a hyperlink or pressing a form button. Refreshing a web page every five seconds could become the modern-day equivalent of Chinese water torture.

If you have a web application that is likely to be sitting and refreshing for long periods of time, and you wish to get rid of the clicking sound without simply turning your speakers down or off, you’re in luck. The good news is that it can be done. The potentially bad news is that turning the sound off is a system-wide feature; no websites you view will click. There is no way currently to specify that an individual page or website should not click. It’s all or none.

To remove the sound, start with your Control Panel.

• On Windows 95/98/2000, doubleclick on the “Sounds and Multimedia” icon and choose the “Sounds” tab.
• On Windows XP, doubleclick the “Sounds and Audio Devices” icon and choose the “Sounds” tab.
• On Windows NT, just doubleclick the “Sounds” icon.

From here, the instructions are the same for each of the above operating systems. Scroll down in the “Sound Events” window until you reach the “Windows Explorer” section. In this section there is a “Start Navigation” option to assign sounds to. In the “Name” Drop down menu select “None” and then hit “OK”.

Done!
