WARNING: Names have been changed in the following article to protect the nerdish.
I can remember from my time in customer support that it is quite an experience to watch an e-mail technician dig through an e-mail's headers. They can tell you exactly where an e-mail has been, what it did along the way, and I wouldn't have been that surprised if they'd been able to tell what colour shirt the e-mail technician at the other end had been wearing!
Now, I can't quite do that but I thought it might be interesting to write a little about what some of the gobbledy-geek-speak in mail headers means. If you feel inclined after you've read this article, open up the mail headers on one of your e-mails (preferably one from overseas) and see what you can decipher for yourself.
Checking Mail Headers in Outlook Express
1. Right-click on the e-mail in your inbox.
2. Left-click on Properties.
3. The box that pops up will have two tabs: General and Details. Select the Details tab.
4. If you'd like a bigger view, click the Message Source button to the bottom left and
adjust.
Checking Mail Headers in Outlook 2000
1. Right-click on the e-mail in your inbox
2. Left-click on Options. A box will pop up which includes miscellaneous information about
the e-mail, including its headers.
Checking Mail Headers in Netscape 4.7
1. Select the e-mail in your inbox by clicking on it.
2. On the Toolbar at the top of the program, click View, and then Headers, and then All.
The first thing to understand about mail headers is that they are basically just a list of technical details about your e-mail - who it's from and who it's to. They also contain a list of identification stamps. Imagine it like this: An e-mail from America will have been passed through a number of servers before it reaches you. A mail server is a computer who's main function is to receive an e-mail and pass it on to someone or something else. An e-mail will go through at least a couple of these before it leaves America, and then through at least a couple more here in New Zealand before it reaches your computer. Each time one of these servers deals with the e-mail, it will add a stamp to the headers identifying the server's name, the time, and what it did with the e-mail. It is this sort of information that e-mail technicians become so proficient at deciphering. They need to be proficient too because one mail server can't be relied upon to do or write things in exactly the same way as another mail server. That's why mail headers you look at may look quite different from the ones we'll examine here. Things will be in a different order, some things won't be included and so forth.
Lastly, mail headers are best understood in reverse order. The information at the top is a record of the last thing that happened to the e-mail, so in our examination of the mail headers below, we'll start at the bottom.

These mail headers (let's say) are from my friend Norrie the Nerd who's over in America at the moment participating in the Grand Finale of the International Mastermind Competition. His topic, by the way, is Early Server Development March 1965 - August 1968. We'll start at the bottom and go through them briefly, one block at a time.

The bottom two lines here just contain information about the way in which the e-mail was sent and how it was encoded. This is not the same as encryption. E-mails, are usually sent with no encryption at all. Here it just refers to the way in which the text is to be copied on from server to server in the sending chain. The third line up from the bottom tells me what sort of mail program Norrie was using. Mozilla here means Netscape Mail the version being 4.76. This gives me the clue that Norrie may well not be much of a Microsoft Man. If he was, I'd probably see the words Outlook, or Outlook Express (and the version number) here. I can also see that Norrie's computer is using Windows NT 5 for its operating system. Obviously Norrie doesn't completely hate Microsoft. The fourth line up gives me the message ID. As I stated above, each server stamps an e-mail with something like this. It helps track where the e-mail has been. Records of these stamps are kept at an ISP for a time so that e-mails, or at least their pathways, can be checked or investigated. ID stamps like this are always unique.

These lines are pretty standard and easy to understand. They tell me when the e-mail was sent, to whom it was sent, its subject and so forth.

As we continue to work our way up the headers, we come across a series of paragraphs all starting with "Received:". Again, these are just a series of stamps telling me the name of the server that received the e-mail and which server it received it from. I can see here that at 8:19 a.m. (Eastern Standard Time), Norrie's e-mail to me was sent by a server named vml.mx.voyager.net to another server named d168.as1.yntw.oh.voyager.net. Because I know Norrie was in America at the time he sent this to me, I could hazard a guess that the "oh" in one of these server names represents Ohio. All these server names would be known by the Actrix mail servers, so if I really wanted to investigate this e-mail and find out (hypothetically) why it was delayed for a great deal of time, I could find out who owns those servers and contact them asking for an explanation. You can also see here that the e-mail was given another ID number as it went through (id fB5DJEO94789). Lastly, you'll see that the IP addresses of the servers is given. IP addresses are the numerical names of machines, eg 216.196.54.235. I won't go into detail on IP addresses here, but they're necessary because computers don't actually speak English to each other. They speak Number.

Skipping upwards to the third "Received:" paragraph, I can see the details about when this e-mail finally landed in New Zealand. It seems to have crossed a network owned by Voyager in America until it has reached a server named out4.mx.nwbl.wi.voyager.net. Its short name (out4) probably indicates that its the fourth in a series of mail servers designed to send mail out of the network. The "wi" in the server name would represent another American state (Wisconsin) again. If you had a big network in a big country like the U.S., then putting the location of the server in the server name would seem like a good idea. Out4 gave it another ID stamp (id B10CB11E5) and squirted it across the Southern Cross Cable to a mail server here at Actrix named Creative (Creative is one of two mail servers that Actrix has for receiving mail - the other one's name is Dragon). In effect, Out4 is saying to Creative, "Here is a package for someone named editor who lives near you. Please see that he gets it." Creative then would have taken my e-mail and put it in a folder named editor on a file server (like an electronic filing cabinet). There it would sit waiting for the next time I logged on to check my e-mail.

Delivered-To: editor@creative.actrix.co.nz
The last block on our way up the mail headers tells me about the time that I checked my mail. A POP3 server (special servers designed to get mail out of the mailbox [mbox] on the file server and download it to you) at Actrix named Ragas used a program named cucipop v1.31 (and released in May 1998) to retrieve that e-mail from the editor mailbox for me. Again, various date, time and return path information is given. You'll see that the Delivered to: field includes "creative" in my e-mail address - simply indicating that Creative was the name of the server through which the e-mail was received for me.
Okay, that will probably do for this article. I hope it hasn't been too geek-based. I'll close by reminding you that e-mail headers are always different, depending on where the e-mail has been, what servers have touched it and so forth. If you have a look at a few examples of your own, though, you should be able to decipher most of them in no time at all. If you'd like to delve a little more into what happens behind the scenes when you're online, you could try the "What happens When I Click Connect?" article in the May 2000 newsletter.

Thanks, John, for your article. John Anderson works on the Actrix help desk, and hopes to contribute articles to the newsletter over the next few months. -Ed.
This article will give a brief overview of what Open Source is, where it comes from, and how the fruits of it, like Linux (www.linux.org) or Apache (www.apache.org) may benefit you. If you're not sure what I'm talking about - read on.
Open Source means that the "source code of a computer program is made available free of charge to the general public" (www.webopedia.com). The source code is essentially the instructions written by programmers who create applications (programs). A full definition of Open Source can be found at the following site, www.osdn.com/osdocs/01/01/15/1818201.shtml. The Open Source Initiative, a non-profit corporation which is responsible for Open Source certification describes the benefits behind this idea as:
When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing. (www.opensource.org)
Conventional Software is developed by a company or companies usually in a closed way. The code is their property and they do not allow it to be viewed by others for fear of loss of competitive advantage. This means that they benefit financially, but their customers often do not, as they have purchased a product that has not always been fully tested. Open Source benefits from the cooperation of many people towards software that does not have, for example, the plentiful bugs of several popular operating systems. This does not mean that all Open Source software is bug-free, but it does mean that many security holes, viruses and just plain bugs can be spotted before damage is wreaked worldwide by the likes of the 'Love Bug' worm. For example the Open Source Apache web server is so called because it required so many patches when it was initially created for it to work, it was "a patchy server", however looking at the Netcraft Web Server survey (www.netcraft.com/survey/), the evolutionary method of Open Source has meant that the Apache webserver has come to dominate the market, largely because of its stability. If you've been to the Actrix website then you've been to a site using Apache.
The phrase "open source" was a result of a strategy session held on February 3rd 1998 in Palo Alto, California. Those present gathered to discuss the future of Linux (a popular Open Source operating system) and included Eric Raymond, writer of the influential software development article The Cathedral and the Bazaar (www.tuxedo.org/~esr/writings/cathedral-bazaar/). The stimulus for the meeting was Netscape's announcement that they were going to give away the source code of their browser, apparently inspired by the article written by Raymond. While the phrase is new, the concept of Open Source is not. This concept stretches back to the early days of the Unix Operating System and later the Internet in the 1970s. The spirit of pioneering and cooperation from these times is the basis on which Open Source is built.
So how are these Open Source individuals protected from exploitation by less scrupulous individuals? There are a variety of licences which are used to prevent this from happening. One example of these licenses is the General Public License or GPL, as it is often known, which states in its preamble:
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. (www.osdn.com/oslicenses/01/07/05/1711204.shtml).
There are number of other licences that are also used for Open Source and similar project which can all be viewed at the Open Source Development Network at www.osdn.com.
So what does this all mean?
Open Source software encourages security and high standards due to the greater degree of scrutiny. Linux, arguably the greatest success story of the Open Source movement, is an operating system that is fast rivalling Windows in the office market and is crossing over into the home market now. The Star Office system produced by Sun which can be used on Linux is compatible with the Microsoft's office suite and is a definite contender. Thanks to Open Source there is a viable alternative developing to counter the monopoly of Microsoft in the area of desktop applications such as Word, Excel and so forth. You know that the software giant is feeling threatened when representatives like Jim Allchin, Microsoft Corporation's Platforms Group Vice President, describe Open Source as threatening the "American Way" meaning it would seem, Microsoft's way.
If you want to try one of the fruits of the Open Source try the dramatically named browser Mozilla, at www.mozilla.org. I've been using it for several weeks and now have it as my browser of choice. A passionate New Zealand perspective on the benefits of Open Source can be found at the following website created by the New Zealand Open Source mailing list (www.openz.org).
Definitions can be tricky, the differences and philosophy behind free software can be found at the GNU website (www.gnu.org/philosophy/words-to-avoid.html), for more information about GNU read next month's installment: Looking at Linux and GNU

Okay, so you've had your computer for about a year, and you notice that over time, your mouse seems to have been sluggish. It almost feels like your mousepad is too slippery and the mouse ball isn't turning as well as it should. You have to press hard and run it across the mousepad a couple of times in order to get the pointer where you want it. Does any of that sound familiar?If so, you might just have a mucky mouse. You may be tempted to go out to the PC Company and buy a new one, but chances are you won't have to. All you need to do is a little gentle mouse maintenance to have the little rodent speeding around your screen once again.
Hint: Carry out the cleaning
instructions below with your computer switched off. It is pretty hard to remove and
replace the ball cover without clicking all sorts of mouse buttons all over the place.
Cleaning a mouse is pretty easy. You should see that the underside of your mouse has a round turning cover plate through which the mouse ball is just able to make contact with the mouse pad. Turn this cover plate anticlockwise to release the window and remove the ball. Please resist the temptation to see how bouncy the ball is. Inside a standard mouse there are three plastic rollers, and the chances are that each will be ringed with tightly wound fluff. Gently scrape the fluff away with something small (e.g. a penknife blade) until all the plastic is clean and exposed again. Be firm but gentle. It is the only way to deal with mice. Replace the ball and cover, and you should find your mouse has a new lease of life.
The specimen pictured here is a skody individual indeed. The picture reveals two of the rollers (you can see one of the thin black ones near the top of the hole and the larger white one to the lower right. The white roller has an obvious ring of dirt around it that probably needs to be picked out with tweezers.
You can also play with your mouse settings. These can be found, for Windows machines, under "Mouse" in your Control Panel. (Click the Start button, then Settings, then Control Panel, and then doubleclick the Mouse icon. Under the Mouse Properties box that pops up you can change your mouse from right to left handed, select a different pointer, as well as a few other things. You can adjust the speed at which it moves too. Go easy here - getting used to a fast mouse after using a slow one can be as difficult as it was to first learn to use one at all!
Mouse settings for a Macintosh are found in the Control Panel (Apple menu/Control Panels/ Mouse) for all Macs apart from OS X. For OS X, try Preferences/Mouse.

Wired recently covered the interesting developments in a big fuss created by the International Firm KPMG over a harmless link. Weblogger Chris Raettig has made international headlines after being formally asked to remove the link to the company from his site corporateanthems.raettig.org, by KPMG. As the writer of the article states "several website owners were wondering whether KPMG's Internet acumen was really worth anything at all, as it announced a policy that seemed to breach the most basic freedom on the Web -- the freedom to link to any site you want to." The whole saga, and the reason Raettig wanted to link to KPMG in the first place, is quite amusing and revealing. Click the link below for the full story.

Thanks for your attention if you have read this far.
Many of the articles were a little on the nerdy side this month. That wasn't intentional -
just the way things panned out. I hope there was still something here for you this month.
As always, your feedback is appreciated. I enjoy suggestions for content and look forward to comments in general. In particular, I'd love to hear from you if you have found something online that's neat enough to share with others. Any suggestions for Interesting Sites receive a free Norrie the Nerd Actrix chocolate bar. Old Norrie's been a bit quiet lately, but if you'd like to find out more about him, including his life story, you can find it at www.actrix.co.nz/users/norrie.
I tend not to check my editor e-mail at home. That mailbox receives around 40-50 messages a day, the vast majority of which contain viruses (thanks to all those infected who leave my messages in their inboxes), so if you write to me on the weekend or after hours, please understand if you don't hear back right away.
Take care through January. Once again I'd like to take the opportunity to wish you all the best for Christmas and the new year. Actrix thanks you for your loyalty and support, and at times for your patience also.
