Mozilla Firefox at KDE Ubuntu (Kubuntu)

Tuesday, March 24th, 2009

Lately, I upgraded my Operating System with the KDE Desktop, although all I want before is to change my Gnome Ubuntu theme but while surfing, I’ve read a site that suggests me to install a KDE Desktop which I did, and the installation lasted for at most 30 minutes through Ubuntu’s terminal

sudo apt-get install kubuntu desktop

the new desktop looks like the proud Windows Vista from Microsoft, from the widgets down to its features, it has a lot of similarities compared to the latter Operating System. Anyway, back to my problem with the Mozilla Firefox, this said Internet browser works very well with Kubuntu, but there is a bit problem, since I manages sites such as My anyInput Page, My anyAssets Page, My anyInfos Page, My anyHotels Page, My anyInv Page, and My anySupply Page I need a faster browsing experience, so while doing this, I noticed that Mozilla Firefox hangs up, although I have disregarded this occurrences at first whenever I go login to my yahoomail account thinking it just happen for any reason, but I cannot afford to be delayed in managing the above listed pages. Good thing there is an alternative Internet Web Browser Kubuntu has to offer, it is called the Konqueror, and this is currently what I am using in writing this blog post. However, I will still go back to Mozilla later when I go doing web development codings since there are a lot of things I need to consider in developing sites with the Firefox, Konqueror can also be used to display output on web development codes but Mozilla is the most used Internet browser that is I need to get back into it later. Anyway, I hope I could find some answers regarding my little problem with this stuff. Get back to you later. By the way, I am posting below the images of both Mozilla Firefox, Konqueror and the Kubuntu Desktop as well so that you will have an idea on how is it going on with me here.

Choosing Between Laptops and Desktops

Wednesday, March 11th, 2009

Desktop PC systems have always been and likely always will be the way that most people buy PCs, notebook PCs (also called laptops) have become very popular in recent years. At first they were almost exclusively the province of big business “high rollers” due to their very high cost. Now the cost of some notebooks PCs has come down dramatically, and they have really entered the mainstream. Many people use a notebook as their only PC today, and for some they offer advantages that make them very worthwhile. However, notebooks also represent a trap that far too many people fall into.

Let’s illustrate the reality of desktops vs. notebooks by looking at the relative advantages of each. First, the advantages of desktops over notebooks:

* Price: Desktops are always cheaper than notebooks for comparable performance and features. In fact, they are often half the price or less. (Although part of the reason for this discrepancy is the LCD screen used on notebooks; see below for more on this subject.)
* Performance and Capacity: Most desktop PCs provide better performance than notebook PCs in addition to being cheaper. For example, you can’t get at any cost a standard hard disk for a notebook that is as large as the ones shipping in better desktop setups. You can’t get a 10,000 RPM hard disk for a notebook. You can’t get a 21″ monitor; etc.
* Technology Lag: With rare exceptions, new technologies show up in desktop PCs at least six to twelve months before they make their way to notebooks. Notebook users are always “behind the technology curve” relative to desktop users.
* Reliability: Due to the extreme miniaturization and difficult design constraints inherent in the compactness of notebooks, and the fact that they get moved around a great deal, notebooks are considerably less reliable than desktops. The “rule of thumb” figure I last saw was that a notebook was ten times as likely to require service as a desktop. That seems a bit high to me, but regardless of the exact number, it is significantly more likely that a notebook PC will need repair. They are fragile and must always be treated with care.
* Expandability: Desktops have far more expansion options than notebooks. A desktop PC has expansion slots that let you add any of a variety of thousands of hardware cards. Notebooks now have PC card slots, which are a wonderful improvement over how things were before they were invented. Some notebooks also have available docking stations that can take one or maybe two expansion cards (at considerable expense). Still, there’s really no comparison; desktops are much more expandable.
* Selection: There are thousands of notebook models made by hundreds of companies, but there even more options for desktop units. This is also less of an issue than it was several years ago, but still, you don’t have nearly as many choices for notebooks as you do for desktops.
* Configurability: When ordering a new notebook you will have fewer options for customizing your configuration than you will for a desktop. Most notebook manufacturers have a number of different standard configurations from which you can choose, but limited options beyond that point.
* Upgradeability: Most desktop PCs have a myriad of upgrade options available to them; more memory can be added, hard disks easily replaced, and sometimes, even the system processor can be upgraded at low expense. A motherboard upgrade can be a bit pricey and difficult, but is much cheaper than getting a whole new system while yielding many of the benefits. In contrast, despite improvements in recent years (user-upgradeable memory and hard disks being the most obvious) notebooks have few upgrade options.

And again, having said all of this, bear in mind that notebooks have actually greatly improved in several of these areas over the last few years! This is especially true in the areas of expandability, selection and reliability. Yet still, the gaps persist, and likely always will. Now, let’s take a look at the advantages of notebooks over desktops:

* Portability: Notebooks let you “take your PC with you”. You aren’t tied down to one location; you can work at the office and your home with the same equipment and the same data. You can work in transit, and take everything with you on trips.
* Power Savings: Notebooks use much less power than desktops.

That’s pretty much it! And in fact, that’s what the decision of desktop vs. notebook comes down to: how important is the portability to you? Do you really need to take the machine with you? For many businesspeople, the answer is a resounding “YES!” However, some folks (including myself once, many years ago) talk themselves into buying notebooks by greatly overestimating how much traveling they will do, or based upon romantic notions of writing the Great American Novel on the beach in the moonlight. Unfortunately, that’s not how things usually work out in the real world. :^) So be sure to be honest with yourself about your portability needs.

So guys, have you seen the difference between the two? So the next time you go shopping for your computer, consider this thoughts first, as it may have a great factor in improving your life. Always weight the pros and cons. The decision you make will always depends on how will you use this new computer and what is this for. Desktop Computers are intended for a fixed office jobs while Laptops are for the business men who goes on and off the office while still needs to optimize their time while on travel.

More on this later.

How To Utilize Desktop Monitor Instead of Laptop’s LCD in Ubuntu Intrepid?

Friday, January 30th, 2009

So, I have my laptop and I am bringing it in the office. But as time goes by, I realized that I might over use my laptop’s screen, since LCD screens have lower lifespan compared to the CRT (Desktop Screen/Monitors). I am bringing my laptop at office, because all of my important documents and accounts are stored on it, so there is no choice left for me. One day, it came to my mind why not use the company’s desktop while using my laptop, in that way, I could save my laptop LCD’s life while still use my laptop efficiently. So, how did I temporarily disabled my laptop screen and utilize that of the company’s?

Doing this in Windows Operating System is just in a blink of an eye, same as with the Linux environment but is more secured, well that is the essence why I decided of having an Ubuntu software to govern my machine.

So, I will make the procedures in step by step way on How To Utilize Desktop Monitor Instead of Laptop’s LCD

1. Connect your CRT data cable to the laptop’s extended video port.
2. Start your Ubuntu Operating System.
3. Log-in to your account.
4. When you are already logged - on, Click on the System > Preferences > Screen Resolution menus.
5. On the Screen Resolution Settings Window, uncheck the Mirror Screens checkbox. Then you will see the current monitors being used by the system, both (CRT and Laptop) monitors are displayed since you are connected currently to them.
6. Click on the Laptop (your screen viewable measurement), i.e: Laptop 14″ , then click on the “Resolution” menu item and set it to “Off” using the drop down menu .
7. Your Laptop screen is now disabled.

** If you want to bring the display back to your Laptop LCD, follow steps 4 until 6 and set the “Resolution” to your desired values from the drop down menu i.e.: 1024 x 768, etc.

Enjoy the tweak! More on other tweaks later.

Computer Viruses: The Danger of it

Friday, August 29th, 2008

The danger of computer viruses lies in their ability to replicate themselves and spread from system to system. Most computer viruses are merely annoying — the most common reported by online volunteers are those that alter Microsoft Word macro functions, and those that attach meaningless files to emails. Viruses begin to work and spread when you start up the program or application of which the virus is present.

Antivirus programs perform two general functions: scanning for and removing viruses in files on disks, and monitoring the operation of your computer for virus-like activity (either known actions of specific viruses or general suspicious activity). Like viruses and similar programs called worms, modern malware copies itself onto unsuspecting computers via e-mail attachments, Web pages or more direct attacks. A virus is inactive until you execute an infected program or application OR start your computer from a disk that has infected system files. Viruses work the same ways in Windows or DOS machines by infecting zip or exe files.

Viruses:Malicious Softwares

Thursday, August 28th, 2008

Viruses are one of the several types of malicious software or malware. Viruses that are common in the wild are mostly relatively fast to extremely fast infectors. Although some viruses are merely disruptive, others can destroy or corrupt data or cause an operating system or applications program to malfunction. Viruses typically do this by avoiding suspicious programs, such as small program files or programs that contain certain patterns of ‘garbage instructions’

Several thousand computer viruses are known, and on average three to five new strains are discovered every day. Antivirus programs and hardware have been developed to combat viruses. A computer virus usually attaches or inserts itself to or in an executable file or the boot sector (the area that contains the first instructions executed by a computer when it is started or restarted) of a disk; those that infect both files and boot records are called bimodal viruses. In a common parlance, the term virus is often extended to refer to worms, trojan horses and other sorts of malware, however, this can confuse computer users, since viruses in the narrow sense of the word are less common than they used to be, compared to other forms of malware.

Authors of Computer Viruses

Wednesday, August 27th, 2008

Viruses are written by anonymous programmers, often maliciously, and are spread on floppy disks, CD-ROMs, and via networks and e-mail attachments. Viruses are programmed to do a series of things: multiply, infect as many files as possible and then to launch some kind of attack. A fast-spreading, virus-like infection dramatically slowed Internet traffic, overwhelming the world’s digital pipelines and interfering with Web browsing and e-mail delivery. More comprehensive anti-virus and anti-spyware software installation will normally take longer as this involves lengthy examination of your entire computer (not just the hard-drive working area) and removal of various active and dormant files, programs etc.

Every computer user, whether connected to the Internet or not, should be protected by anti-virus and anti-adware software. A computer virus is simply a piece of software code that is written maliciously to cause problems on computer systems. Downloading files from the Internet leaves you very susceptible to viruses. The virus can be attached to an e-mail, even through a seemingly innocuous file such as a mage. In fact, most antivirus software packages now come with a default setting to automatically update the program via the internet with the latest protection.

Viruses: Threat for Computers

Wednesday, August 27th, 2008

The danger of computer viruses lies in their ability to replicate themselves and spread from system to system. Most computer viruses are merely annoying — the most common reported by online volunteers are those that alter Microsoft Word macro functions, and those that attach meaningless files to emails. Viruses begin to work and spread when you start up the program or application of which the virus is present.

A macro virus is a virus that exists as a macro attached to a data file. In most respects, macro viruses are like all other viruses. Many people do not think that viruses can reside on simple document files, but any application which supports document-bound macros that automatically execute is a potential haven for macro viruses. By the end of the last century, documents became more widely shared than diskettes, and document-based viruses were more prevalent than any other type of virus.

Antivirus programs perform two general functions: scanning for and removing viruses in files on disks, and monitoring the operation of your computer for virus-like activity (either known actions of specific viruses or general suspicious activity). Like viruses and similar programs called worms, modern malware copies itself onto unsuspecting computers via e-mail attachments, Web pages or more direct attacks.
