Blogs are revolutionizing the way businesses interact with their customers. To elevate blogs to the next level, you may want to embed video in your business blog. Video is becoming increasingly in demand online. If you heard of YouTube, you know the impact of video online. Why not take advantage of this revolution? You can make your blog more entertaining when you include video. You may provide short clips about using your products, or you could make short presentations about your services.

Don’t confuse video blogs with online commercials, because the two are not at all the same. Video blogs are not supposed to be shameless plugs or infomercials. When you offer video in your blog you are providing valuable information in a different form. Instead of entertainment, think value. That, of course, doesn’t mean that your video should be boring. On the contrary, the more exciting you make it the more buzz it will generate. Webinars are quite common tools that would benefit your blog.

We won’t go into the details of how to get your videos on your blog, but it is easier than you think. Don’t worry if you don’t have video equipment worth millions of dollars. Most digital video recorders are more sophisticated to day than much of the video equipment professionals have used in the past.

One of the most important aspect of video to remember is that it is using much more bandwidth than text. Be sure you check with your hosting company to make sure there is enough bandwidth for you to embed video in your blog. As video is becoming ever more popular, video hosting providers have made it very easy for the end user to add video content to their blogs.

Having used a desktop computers and notebook computers that had been officially supplied by the company where I was employed, there was no need to worry about what type of notebook computer or whatever configuration that was required in my work.

So when I finally had to purchase my own notebook computer for personal private use, I found myself facing a myraid of questions. Just what should I look out for when buying my own notebook computer?

First, I found I had to quantify my own needs for a notebook computer. Having quantified my needs, which was to do a lot of number crunching and to perform technical analysis and charting of stock prices online, I found that even low priced models could perform work that was demanded by my needs.

I was pleasantly surprised that my needs did not demand a high priced model.

Secondly, the notebook computer I required would need to be sufficiently light. In the process of identifying the notebook computer, I decided I did not need a subnotebook, as most notebook computers weigh between 5 to 7 kg, with a subnotebook weighing at 5 kg or less.

The standard notebook computer was sufficient for my needs coming with some wordprocessing software that was already installed as part of the package that comes with the computer and with Internet access capabilities. All I need was to install my specialized technical analysis program to monitor the stock prices.

At the same time, advances in notebook computer technology ensured that I had wireless technology and can hook up online at any hotspot outlet. This would allow me to have mobile wireless access anywhere I go. I could also use a pen drivefor additional mobile storage.

Tri Peaks Solitaire is a fun, and popular solitaire game, combining elements of Golf Solitaire and Pyramid Solitaire. It has an interesting scoring system, which can lead to much higher scores when you DON’T play all the moves you can.

There are 2 keys to getting a high score in Tri Peaks Solitaire:
- Clear each Peak.
- Form long sequences.

You get quite a lot of points for clearing a peak. You get 15 points for clearing the first peak, 15 points for clearing the second peak, and then 30 points for clearing the last peak. Thats a total of 60 points, which shows that it is definitely worth while getting rid of all the peaks, and unless you can form an incredibly long sequence, it’s always worth trying to clear the peaks.

The second key to doing well at Tri Peaks Solitaire is to form really long sequences, where you do not deal a card from the talon.

The Tri-Peaks scoring system will give you one additional point for every card you move in a sequence. So the first card you move gives you one point, the next card gives you two points, the next card gives you three points, and the next card gives you four points, etc. The sequence ends as soon as you deal from the talon, and the sequence begins at one point again.

This system is interesting because it often makes sense to not move cards as soon as you can.

There are 2 ways to illustrate this.

What do you think the difference in scoring would be between one 12-long sequence versus two 6-long sequences? Most people know the long sequence will outscore the shorter sequences, but not many people realise by how much!

The 12 long sequence gives us a score of 1+2+3+4+5+6+7+8+9+10+11+12, which is 78.

Surely the two 6-long sequences won’t be too far behind?
Well, we get 1+2+3+4+5+6 for the first sequence. And then we 1+2+3+4+5+6 for the second sequence.

The total is only 42! Even though the same number of cards were removed, the difference in scores is 36 points!

OSPF is a major topic on both the CCNA and CCNP exams, and it’s also the topic that requires the most attention to detail. Where dynamic routing protocols such as RIP and IGRP have only one router type, a look at a Cisco routing table shows several different OSPF route types.
R1#show ip route
Codes: C – connected, S – static, I – IGRP, R – RIP, M – mobile, B – BGP
D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area
N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2
E1 – OSPF external type 1, E2 – OSPF external type 2, E – EGP
In this tutorial, we’ll take a look at the difference between two of these route types, E1 and E2.
Route redistribution is the process of taking routes learned via one routing protocol and injecting those routes into another routing domain. (Static and connected routes can also be redistributed.) When a router running OSPF takes routes learned by another routing protocol and makes them available to the other OSPF-enabled routers it’s communicating with, that router becomes an Autonomous System Border Router (ASBR).
Let’s work with an example where R1 is running both OSPF and RIP. R4 is in the same OSPF domain as R1, and we want R4 to learn the routes that R1 is learning via RIP. This means we have to perform route redistribution on the ASBR. The routes that are being redistributed from RIP into OSPF will appear as E2 routes on R4:
R4#show ip route ospf

O E2 5.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0

6.0.0.0/32 is subnetted, 1 subnets

O E2 6.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0

172.12.0.0/16 is variably subnetted, 2 subnets, 2 masks

O E2 172.12.21.0/30 [110/20] via 172.34.34.3, 00:33:32,
Ethernet0

O E2 7.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0

15.0.0.0/24 is subnetted, 1 subnets

O E2 15.1.1.0 [110/20] via 172.34.34.3, 00:33:32, Ethernet0

E2 is the default route type for routes learned via redistribution. The key with E2 routes is that the cost of these routes reflects only the cost of the path from the ASBR to the final destination; the cost of the path from R4 to R1 is not reflected in this cost. (Remember that OSPF’s metric for a path is referred to as “cost”.)
In this example, we want the cost of the routes to reflect the entire path, not just the path between the ASBR and the destination network. To do so, the routes must be redistributed into OSPF as E1 routes on the ASBR, as shown here.
R1#conf t
