Desktop vs Laptop




There use to be a time when laptops were less powerful than desktops. But this is not true anymore. For every powerful PC, you can buy an equally powerful laptop computer.

So what is the reason you would buy one over the other.

Portability

Laptops have the advantage of being easy to carry around anywhere. If you are going on a business trip and you need to work, a laptop is the solution.

You will have no problem surfing the internet as long as there is a connection available. You can also do presentations anywhere. You can run your slide shows made with either Powerpoint or Flash.

Laptops can also handle processor intensive uses. In fact there are some graphic artist and programmers who now work exclusively with a laptop.

If you are a writer, and you like to write while you are visiting exotic places, you can't go wrong with a laptop.

Speaking of graphic artist, there are many programmers who bring along their laptop when they are shooting on location. The reason for this is that they can immediately download their pictures so that they can take advantage of the larger storage capacity than what is provided by their digital camera.

Replaceable Computer Parts

The one disadvantage of laptops as compared to desktops is that their parts are not as replaceable.

Often you have to go to the manufacturer if you need them fixed or you need to replace a broken component.

A good example is a monitor problem, if the monitor broken you will need it repaired by the manufacturer.

Unlike when you have a desktop computer, you will just need to buy a new monitor.

With desktops, if the graphics card, memory, sound card, etc. gets busted, you can simply buy a new one.

However, desktops should be left to stay in one place. It can either be in your office or at home. Because they are just too impractical to carry around.

Summary

Therefore when you are thinking of buying a desktop vs laptop, you buy a laptop because you need a portable computer or buy desktop if you want a computer that can easily be fixed.

PLDT Frequent Disconnect Solution

This is just one possible solution if you are finding that you're PLDT MyDSL keeps getting disconnected.

The current standard modem for PLDT MyDSL is Xyzel P-### series. You will notice that it has three LED lights as its indicator.

1. DSL LED
2. Ethernet LED
3  Power LED

Some of you may encounter a situation that on certain hours your Power LED turns red and your DSL LED keeps dying. But then after a few hours the Power LED finally turns green and your Internet connection becomes stable.

For a long time I thought this problem was caused by the DSL server dying in the main office or because of too many subscribers, the network becomes strained  due to overcapacity.  But apparently, this was not the case.

I found this out when I unplugged all the cables (rj45 and rj11) connected to the Zyxel modem except for the power.

I discovered that the Power LED was still red. So that means the problem has nothing to do with being connected to the PLDT server.

I discovered that somehow the voltage supply provided by the electricity company fluctuates depending on the time of day.

In my case from 6pm to 11pm our voltage supply drops below 220.   It seems that this is the peak hours in my neighborhood when a lot of people are using a lot of electricity.

Most normal appliances can handle this fluctuation and but that is the problem with Zyxel modems.  If the voltage supply drops they become very unstable. Hence you keep getting disconnected from the Internet.

Solution:
I requested the serviceman to replace my Zyxel adaptor with auto-volt adaptor.

Using Google Earth for Time Travel

You are probably raising your eyes brows and saying what is this guy talking about? Can we really travel through time using Google Earth as our time machine?

Sure. Why not?  But it is not the kind of trip that you expect. First off, your journey will be less perilous and you don't have to worry about affecting the time space continuum.

1. Open Google Earth
2. At the top of your screen you will see an icon that looks like a clock.
3. This will give you a slider with a starting year and ending year indicated.

You can use this slider to see what changed occurred at a your chosen place at certain points in time.

Lets time travel in Beijing.

1. Type 2008 Olympics Stadium in the Fly To search box.

2. This will take us to the National Stadium in Beijing.

3. Click the Slider and drag it to 2001. Then slowly slide it to 2008.

You will see how the National Stadium progressed from being just a barren land to what it is now today.

Nice huh. 

There are other things you can do with this software. To know more you can refer to my article Google Earth Free Version.

OpenOffice: Microsoft Office Alternative

You are of course familiar with Microsoft Office. It is one of Microsoft's most successful product.

OpenOffice is the Microsoft Office Alternative software offered by Sun Microsystems, Inc, now owned by Oracle Corporation.

The first time I used Openoffice, I said to myself. What the hell?. This software is freaking ugly.
Aside from aesthetic shortcomings, the software suffered from incompatibility with Microsoft Word and Excel File format which is still the dominant electronic document formats today.

I uninstalled it because there was really no incentive for me to use it. For example, if I were to send a resume to a prospective employer, they are going to expect a Miscrosoft Word document format. And since OpenOffice was not compatible, the document I send will not appear as I've intended.

Well that was two years ago.

I recently tried Openoffice again and I found that it has greatly improved. It is no longer aesthetically distracting and seems to be more compatible with the more popular office formats.

So if you are short of cash or just plain stingy, you can have this document software absolutely free.
