Micro - chips inserted into your body?

This technology is already being used to track animals!
This particular chip only carries a unique 16 digit identification number, not any data of substance, like medical records. Once scanned, that number can unlock a central records database.

It's hardly a very secure technology, as there's no encryption involved. You may as well just keep the 16 digit code in your wallet. Sure beats spending a couple hundred bucks on the implant.

Coincidentally, most credit card numbers also have 16 digits. And imagine if your code was compromised and you had to change it like a credit card. Would that mean a new implant, or can they change it with an office visit?

The real security risk is the central database that holds your entire medical history. If all it takes is a 16 digit code to access your medical records, what's to stop an insurance company from acquiring the code as a condition of being insured? What's to keep people from entering random numbers in the hopes of getting a hit. Even credit card accounts have PIN or passcodes you use to access your data.

It would seem to me there's a better way to do something like this...like a smart card that requires a PIN.

From a privacy and security standpoint, some would be concerned that the increased availability of the medical (or other private) information by having it accessible in that chip embedded in your body would constitute an unreasonable risk. Just as people are encouraged not to carry their Social Security card with them because of the risk of having it stolen, so one might reasonably be concerned with the risks involved in carrying so much sensitive and private information such as medical records.

From a more philosophical and religious standpoint, some would be concerned that this type of procedure further denigrates that which makes us truly human, our natural limitations. In contrast, others would point out that it is very much a natural human quality to overcome limitations using technology.

What do you think?

Renaissance. art and technology

Do artists today need to know the language of technology in order to communicate their ideas effectively?"

I would say that technology, in the sense that you are referring to it, is a tool, rather than a language. For me, the language of art is in the concepts, form and symbols it uses, whereas the tool is the medium used.

Of course, art can be just about anything. Technology can, and often is, incorporated into art.

think of Da Vinci's drawings. They are both technology and art.

As a tool, technology is no different to the paints and pigments that artists used in the renaissance period. We can go back even further, right back to the beginning of art, to the cave paintings in Lascaux, France 30000BC. Even then, those who made the paintings need a technique to do them with. They need to understand how to get pigments, and how to use them. they also need skill, drawing skill.

In the Renaissance period, great artists like Michelangelo and Da Vinci used to have students working for them. The student had to learn to learn how to mix pigments, make brushes and stretch canvas and so on. In return, he got to see how the master worked. The paints, brushes and cnavas are all technology, and great artists didn't want to be bothered with that, but they needed it. So the student master system worked well. The students had to invest a lot of time in the beginning in working with pigments, which may involve crushing materials, grinding, mixing and so on, often for many years.

The renaissance period is also interesting because another kind of technology was being investigated, and that was application of geometry, in the form of perspective. A successful renaissance artist not only had to be able to prepare materials, but were also required to have technical knowledge of geometric construction and perspective. That special knowledge, which is independent of talent, can also considered to be technology.

My point is that technology has always been around, and yes, it has always been necessary to know how to use it to produce art. Perhaps the simplest form of it is understanding pencils and paper, for no artist ever became a great artist without this simple drawing skill.

Network Hardware vendors

I am giving away all of my secrets. Anyway...Here is a list of vendors to think about in designing networks. You will have to desigin networks in future classes in this program. I guarantee it. Remember to think about redundancy expecialoly in the core / distribution / and access layer. Redundancy allows one part of the network to be either worked on or fail and your network will not go down. Think logiically and it will all make perfect sence.

Hardware

Q-Hardware to use (firewalls, routers, switches, phones, servers...)

A:Industry Standard UTM firewalls are:

1- Juniper
2-Cisco
3-SonicWall
4-Checkpoint

High-End Routers:

1-Cisco
2-Juniper

SOHO Routers:

WEB2.0 and Analytics

Heard of google analytics ? It is the hotest new trending software on the internet.

In GA, the following information is listed

117 Visits
153 Pageviews
1.31 Pages/Visit

So what are the differences btwn visits, pageviews, and pages/visit.
Visit - unique visitor
Page view - a single visitor may very well view more than one page
1.31 pages/visit - number of page views divided by the number of unique visitors

Re: "why does average time on site sometimes show as zero"?
Analytics is the last thing your page loads, so anyone who leaves before the page finishes will show as having spent no time, or something to that effect. Also, they might not be storing cookies, but I don't know if that's a factor.

http://www.google.com/support/googleanalytics/bin/answer.py?answer=57164
A visitor can view page multiple times before Google stops grouping them under one visit. I could visit the same site twice in 30 minutes and it is still grouped under the same "visit". I could also visit the same page 10 times over the course of 2 days and be treated as a few different visitors as well as visits, if for example if I clear my cookies or if my IP address changes.

Layer 2 or Layer 3 Switch

Should I pick a layer 2 switch or a layer 3 switch. There are also layer 4 and layer 7 switches.
Lets get back to layer 2 or layer3.
Layer 2 only provides routing based on layer 2 information(ie VLAN) where as layer 3 switches will route based on information such as IP addresses.

What are your requirements for a switch?
29x series switches are generally layer 2 only with limited VLAN support

2960G-24TCL is layer 2 - Feattures = Auto-sensing per device, DHCP support, auto-negotiation, VLAN support, IGMP snooping

More.....

L3 switches are fast routers. In Cisco's case, the same IOS runs both on routers and on switches. One of the primary differences is that only a more traditional router can "route" traffic between disparate physical-layer connectivity, i.e. between Token Ring and Ethernet, between WAN (T3, T1, ISDN, etc) and LAN.
Because the L3 switches need to be fast, many of the advanced features of a router are left out, ie. IPX and Appletalk routing, advanced routing protocols like OSPF, IS-IS, and sometimes Quality of Service as well as access-control features.

End of the Blog

Hey, didn’t you hear? Blogs are so 2004. They’re dead now, says Paul Boutin (who also writes for Valleywag) in a piece he wrote for Wired magazine. Here’s his argument (such as it is) in a nutshell:

“The blogosphere, once a freshwater oasis of folksy self-expression and clever thought, has been flooded by a tsunami of paid bilge. Cut-rate journalists and underground marketing campaigns now drown out the authentic voices of amateur wordsmiths.

It’s almost impossible to get noticed, except by hecklers. And why bother? The time it takes to craft sharp, witty blog prose is better spent expressing yourself on Flickr, Facebook, or Twitter.”

http://www.wired.com/entertainment/theweb/magazine/16-11/st_essay

Wow — that’s pretty persuasive, isn’t it? You can’t miss with a great environmental metaphor like that. I guess I had better stop blogging then. To tell you the truth, I’m kind of surprised that Paul didn’t put a headline like “Twitter and Facebook have killed blogging” on his piece. Things are always killing other things in the kind of world Boutin describes. And what evidence do we have that blogs aren’t the place to be any more? Just this: Jason Calacanis quit blogging and moved to an email newsletter, and Robert Scoble is mostly doing video posts and Twittering.

I have actually never been much of a blogger. I actually do subscribe to two blogs but I post little if anything. There are so many entries it is hard to get noticed expecially if the blog is popular.
Too many people on the internet?
I enjoy researching on the internet and will always continue to ...but my blogging days are over.

how to argue


Structure of a Logical Argument

Whether we are consciously aware of it or not, our arguments all follow a certain basic structure. They begin with one or more premises, which are facts that the argument takes for granted as the starting point. Then a principle of logic is applied in order to come to a conclusion. This structure is often illustrated symbolically with the following example:

Premise1: If A = B,
Premise2: and B = C
Logical connection: Then (apply principle of equivalence)
Conclusion: A = C

In order for a conclusion to be considered valid all the premises of an argument must be true, and the logical connection must be valid. I use the term �valid� here specifically to refer to such conclusions, because a conclusion may still be �true� even if it is not valid. This is because it is possible to use wrong information, or faulty logic to reach a conclusion that happens to be true. An invalid argument does not necessarily prove the conclusion false. Demonstrating that an argument is not valid, however, removes it as support for the truth of the conclusion.

Breaking down an argument into its components (sound familiar its a Gillettism)is a very useful exercise, for it enables us to examine both our own arguments and those of others and critically analyze them for validity. This is an excellent way of sharpening one�s thinking, avoiding biases, and making effective arguments.
