3D Chat

DeepGeek — Mon, 31 Mar 2008 22:37:58 +0200

For the most part, I have no curiosity to the Internet "toy" factor. Strangely, I am curious to the 3D chat rage. There is something attractive about 3D chat; that attractiveness troubles me.

My introduction to 3D chat came from Josh — a charter customer of the My^DLLURTH service community. Josh could not get display on his father's LCD monitor while it rested on a computer chassis. With son and computer equipment in tow, Josh came for a system evaluation. Josh and his son were healthy; neither did the computer equipment give any indication of failures. The video failure was attributed to power conditions at home. That was the beginning of … intellectual trouble.

Josh is a social creature. All too frequently, that social character complicates Josh's computer resources. Josh does visit questionable Internet sites; he self-inflicts much Trojan and virus misery. To his credit, Josh accepts his own responsibility and seeks professional help for all facets of his afflictions. In the meantime, he continues affected by social aspects of the Internet. This time, however, I am also affected.

Josh hoped for guidance in enhancing his 3D chat avatar; the chat application is IMVU. The usefulness of IMVU, for my participation, is approximately what IRC provides. I cannot justify the animated avatar. In fact, I cannot use IMVU for my lack of a Microsoft Windows installation. My lack of access did not mitigate Josh's insistence; Josh was single-minded to learn the "tricks" of programming avatar attributes.

Specifically, Josh wanted to alter the apparel for his avatar. There are several articles of virtual clothing available for purchase; the available purchase items do not satisfy Josh. Unfortunately, I haven't desired instruction to impart. Can someone else educate the community?

I can't get Internet

I can't get Internet!

More than a dozen years of providing Internet technical support fails to show DaGeek a more abused trouble report. Qualified technical support agents are quite aware of Internet access procedure, but remote descriptions of symptoms are often ambiguous. The afflicted user, however, describes an untechnical but quite personal understanding of their problem. Most resolutions require clear understandings by both parties.

The agent must assume the role of an expert interviewer. Ask insightful questions. Provoke illuminating answers. Define ambiguous vocabulary. A more successsful approach places "Internet" problems in layers by the OSI model. Using the OSI model will quickly determine where effective remedy to Internet dysfunction is applied.

Significant science is developed for the OSI model, and technical discussion may glaze uninitiated eyes. For the more shallowly interested readers, a quick guide to determining which layer is failing will be more useful. Truly sick readers might read through details of all seven layers and become effective technical support agents. Each layer will eventually link to more detail as this guide evolves. To help readers understand technical details of the extended guide, complimentary controls are planned for each section — just click "Simplify" when science is not needed or "Detail" when science is missing.

This guide evolves with time. Feel free to comment and question. Technical support agents solve many "can't get Internet" problems in a day … but you might have a previously unencountered problem. This guide serves both sides of the solution.

First, guidance for determining layers of failure is most helpful. Knowing points of failure is knowing what must change. Ask the question, "How is Internet not available?"

First, this article comes from the Internet. Perhaps you had to use an alternate computer. Perhaps you found a printed archive. What you have is better called Internet access limitation. Let's compile a list of limitations.

Workstation: Is the limitation on a single computer?
Does the same limitation happen on computers in other buildings?
Knowing, precisely, the scope of affected workstations is very useful to resolution. Connection problems may be for a single computer, a LAN, an ISP or even a peering point.
Routing: Do you have an IP address and netmask?
Do you have a default route?
Can you ping your gateway?
Can you trace a route beyond your gateway?
Routing is essential to Internet access. Find your IP address and default gateway. If you have an IP address, different from 127.0.0.1 (localhost), see if you can ping other addresses. If you can ping your gateway address, you have a connection on the Internet and could be able to reach other Internet locations. Try a traceroute for 12.122.81.97 and see if you reach that (very reliable) peering point.
Hosts: Does 12.122.81.97 respond to a ping request — what about ggr2.attga.ip.att.net?
Does google.com respond to a ping request — what about 64.233.167.99 and 64.233.187.99 and 72.14.207.99?
There is more than one way to connect two Internet hosts. Most people use named hosts (like google.com and youtube.com and amazon.com) but Internet hosts also use IP addresses. Check the local host files and named server configurations.
Application: Can you explore with a browser?
Can you look at e-mail?
Can you chat with messenger or IRC applications?
Does your VoIP telephone work?
Many applications depend on Internet connection. Browsers and e-mail clients are only the more recognized Internet applications. Messengers like ICQ and AIM use the Internet. VoIP uses the Internet. If some part of your Internet function is missing, it is possible that a firewall is misconfigured. Some ISP do not allow using port 25 (sending mail) except by their specified mail server. Peer to peer services like BearShare and Limewire and Kazaa are often blocked. Some workstations are disallowed connection to some websites; other workstations are only allowed a few specific web sites.
Detail: Can you access a web site, but your account services aren't available?
Are some web pages showing red "x" images?
These are signs of software configurations and forgotten passwords. Confirm settings and user credentials.

Sure, it's different

But we can do things OUR way.

For instance, we can make posts visible to anonymous readers, but subject only anonymous readers to unsolicited, but related advertisements. We can reference books from Amazon and add them to our message. We can create (and edit) posts with a WYSIWIG editor to pretty them somewhat.

We can search content, do surveys, use specially formatted submission layouts … the possibilities for this group are truly in the hands of our group admins.

For the time being, we will not be able to post via e-mail. Sorry, but we sacrifice in the interest of usability. This group, with input from users, will evolve to the level of usability which any real group should offer. No more being held hostage to profitability. It's a brave new wyrld.

Now before anyone starts thinking I control this group's content, understand I only administrate this group while the group design evolves. The mydllurth.com domain is mine; being your server admin is a significant responsibility – one I take very seriously. I'll post and offer guidance when I am qualified, but I'll not get in the way of a good thing.

That said, let's get on with business -- the business of supporting each other.
