Laptop Demand Getting Astronomical

Posted in Living With Technology on June 27th, 2008

Laptop computers seem to be the current in thing this year. I just scared that like last year we will have problems getting the latest technology too. Laptop Computers have been an evolving business year on year for a number of years now and it looks like that will continue. The technology cycles are so minute too which makes it all the more harder.

More manufacturers are realising that gaming laptops is becoming big enough niche to chase. With prices coming down and new technology being launched rather rapidly it means that people are getting more value. Gaming laptops are no longer ridiculed by serious gamers because they are actually fairly good. Past obstactles with massive, over heating laptops for gaming are disssapearing and new slimmer, attractive products are being launched. Performance of desktops should infinitely be a light year ahead of laptops but its still encouraging to see. I feel gaming laptops are always exciting to read about because they are constantly pushing the envelope on mobile technology.

For the niche customers using notebooks. With custom built laptops you normally get to discover what make of components is going into the notebook. By being able to negate some add on’s from the spec you can actually save cash on parts you won’t use. Prebuilt laptops are manufactured for people who have like minded requirements and that is probably not you right? Mass customisation of notebooks has got past this problem. Advanced levels of customer care and support can also be found when obtaining custom built laptops. This could be a important attractor to some niche sectors.

We’re seeing some fairly awesome stuff at the minute and I wonder what will be introduced next. The super low cost umpc group seems to be starting all the buzz at this time. The Eee PC just built a new niche division. Buyers need laptops that are light but also big enough to be practical and simple to use. I guess you could say these laptops are already attainable if you’re willing to pay the premium. I can expect its not too long before we start experiencing gaming laptops that weigh nothing. All the companies are striving to come out with the next big portable so it’ll be interesting to survey.

I’d recommend gaming laptop at rizeon.

Browsing Paranoia

Posted in Living With Technology on May 25th, 2008

Are we overdoing personal security in our day to day uses of
computers — especially when we are going online?

I notice that I have developed strange behavior after visiting
secure sites, buying something online, or going to a website
where I needed to enter a username and password to gain access.
When I am done, I log out. But, before going to another website,
I shut down the browser and then restart before visiting another
website.

This level of browsing paranoia stems from the fear that if I
jump from one website to another, there is a risk my username
and password or other information could be grabbed by the second
site.

It does not matter if I am using MSIE, Firefox or Opera. My
behavior is the same. Incidentally, I use Opera more often now
that it has dropped ads. My behavior is the same. Incidentally,
I use Opera more often now that it has dropped ads. See Opera
On My Laptop
.

The thing about my odd browsing behavior is that it is based on
the idea that a malicious website could get user names and
passwords for my previous session. I feel like I have read about
that a thousand times. However, the next site is almost always
from my list of favorites. Unless there has been a change of
ownership or the site has been hacked, I believe those sites can
be trusted. After all, I have accounts at some.

Make Sure Browsers Are Fully Patched

Unfortunately, that statement reinforces the fact that we must
make sure that our browsers are fully patched at all times. Many
high profile sites have been hacked and many tricks used by
criminal minds to divert us to the dark corners of the web. I
try to be careful to use the latest, fully patched version of
each browser at all times. Especially MSIE.

At the same time, I mostly browse the internet from a computer
using the Windows XP operating system. The installed firewall is
turned on. All listening ports are closed. This is the default
on new versions of windows. But, if you are reinstalling an old
version, make sure you are not connected to the internet until
after you turn the firewall on and block all ports.

Post Install Security

When I installed windows, I visited the Gibson Research Corporation
website and ran three important programs:
http://www.grc.com/unpnp/unpnp.htm“>Unplug ‘n Pray, DECOMbobulator, and Shoot The
Messenger. These steps created a baseline for security on my
system. These post-install routines are easy to do. Take only a
few minutes. And eliminate a host of potential worries.

For a second line of defense, I would recommend SpyWareBlaster by
from Javacool Software
. The program tweaks some internal
Internet Explorer settings to block the installation of known
spyware (and similar threats) installers.

However, even with this layered approach to security I still
close my browser when I am switching from secure to insecure
sites — especially after buying something online!

Cisco CCNA Exam Tutorial: A Guide To RAM, ROM, NVRAM, and Flash

Posted in Living With Technology on April 8th, 2008

CCNA exam success depends on knowing the details, and nowhere is this more true than knowing the various components of a Cisco router. This is also where you can quickly start drowning in acronyms! The terms “RAM” and “ROM” probably aren’t new to you, but keeping up with “what goes where” with RAM, ROM, NVRAM, and Flash Memory can be quite a challenge! In this tutorial, we’ll take a look at all four of these components and their contents.

ROM stands for Read-Only Memory. ROM stores the router’s bootstrap startup program, operating system software, and power-on diagnostic test programs (the POST).

Flash memory is generally referred to as “flash” The Cisco Internetwork Operating System (IOS) images are held here. Flash is erasable and reprogrammable ROM. Flash memory content is retained by the router on power-down or reload.

RAM is short for Random-Access Memory. RAM on a Cisco router stores operational information such as routing tables and the running configuration file. RAM contents are lost when the router is powered down or reloaded.

NVRAM is non-volatile RAM. By “non-volatile”, we mean that the contents of NVRAM are not lost when the router is powered down or reloaded. Where RAM holds the running configuration file, NVRAM holds the startup configuration file. If NVRAM is empty when the router reloads, you will be prompted to enter setup mode.

Success on the CCNA exam depends on keeping these terms straight and knowing their contents. Know the contents of each, pay special attention to what is lost on a reload and what is not, and you’re on your way to CCNA exam success!
