Upgrading the Sound on your Home Computer

noreply@blogger.com (GUDANG ILMU) — Fri, 27 May 2011 15:10:00 -0700

Computers these days are becoming more than just an avenue to surf the web and do word processing. They are becoming multimedia stations that allow us to watch movies and listen to the latest music. Especially with new solutions such as renting DVD's online and pay per download music downloading programs. This is why having good sound on your computer is

important for the best possible multimedia experience.

There are two ways you can increase the quality of sound coming from your computer. I will discuss both.

The first would be to upgrade, or get a new, sound card for your computer. The quality of the sound signal being sent from your computer is determined by the sound card. Also the amount of channels that are being sent, and the number of connectivity options you have. This is why having a good quality sound card is important. There are several cards on the market that can deliver a great listening experience.

The second way to enhance your sound quality would be to get a quality set of speakers. There are an infinite number of options you have in this regards. You can get a standard 2 speaker system, a 2.1 speaker system (2 speakers and a subwoofer), a 4.1 system and the ultimated 5.1 system. The most enhancing system would be the 5.1 system.

The 5.1 system consists of 5 speakers and a subwoofer. The subwoofer will deliver the bass and the low frequency sounds. The other speakers would be positioned strategically around the room to give the best array of sounds.

Computers today are not the simple machines they were years ago. They have the capabilities to be a lot more. With this in mind utilizing these capabilities will be very cost effective. Now you do not need to buy a stereo system and a television. A computer can fulfill both these duties.

Device Drivers Important to Know

noreply@blogger.com (GUDANG ILMU) — Fri, 27 May 2011 15:09:00 -0700

Not many people know about device drivers until they need to find one, be it for a printer or most commonly a modem driver. Finding one can be very difficult to say the least if you are using HSP based modem drivers.

What is a Device Driver?

Every device, be it be a printer, modem, or keyboard, must have a driver program. Many device drivers, such as the keyboard driver, come with the operating system. For other devices, you may need to load a new driver when you connect the device to your computer. Note that in the older DOS systems, drivers are files with a.SYS extension. now in Windows environments, drivers often have a.DRV extension.

What do they do?

A device driver is nothing more than a glorified translator which fits between the device and programs that use the device. Each device be it a modem or printer has its own set of commands that only its driver knows. That bieng said, however most programs access devices by using generic commands. The device driver, therefore, accepts generic commands from a program and then translates them into specialized commands for the device.

Finding them:

Finding a driver can be very difficult as most manufactures manufacture a device and after 2 or 3 years change and make a different version. Finding a driver for your device becomes a task as the manufactures remove the drivers from their website and refuse to support them. They hope that you will upgrade to their new line of products, but there is no need if you know where to find your drivers. Try the following website which not only has more than 2,000 drivers but finds what you are looking for, free.

Remember, don't upgrade unless you want to. There is no need to buy new, when the old printer or modem worked just fine!

PasswordsPro - Welcome to mysterious world of hashes!

noreply@blogger.com (GUDANG ILMU) — Fri, 27 May 2011 15:08:00 -0700

Many know that hashes are encoded passwords. Using hashes greatly increases safety of passwords storage, for example, in the forums, databases, etc. Let's assume, forum administrator has password "admin12345" which is certainly stored in the forum database. What is to be done to authenticate user on the forum? Input password shall be compared with "admin12345". If they match, administrator may enter the forum. It seems working great, but what if someone unautorized gets access to database and sees open password and can easily log in as administrator. Here hashes come to rescue. For instance, MD5-hash for "admin12345" password will look like "7488e331b8b64e5794da3fa4eb10ad5d" and it's exactly what we store in our database, not a password itself. During user authentication input password is converted to hash to compare with the hash stored in the database - if these two match that means input password is correct and logging on is successful.

But what if we need to perform reverse action - to try to restore password from hash? It's impossible to do that directly, as any hashing algorithm is password's checksum calculation. This process involves irreversible mathematical operations like logical operation AND, etc. For example, even knowing Y and Z we can never find exact X from "X AND Y = Z" equation (all we can do is calculation of range of possible X values satisfying the equation).

So if we need to find password for certain hash there's the only way to generate hashes for different passwords and then compare hashes we got with source one. If they match, it means exactly the source password is found as possibility of collision (i.e. another password which has hash matching our source hash) is very low - for example, it is (1 / 2128) in case of MD5-hashing.

Here PasswordsPro comes in handy - it is a professional tool for passwords check and recovery of passwords for hashes. It's main purpose is to recover your forgotten password when you have only one hash, or check passwords for crack-resistance.

This unique program supports about 40 types of hashes, and any new type can easily be added through writing your own DLL-hashing module.

Built-in types of hashes:

Supported types of hashes: MySQL, MySQL5, DES(Unix), MD4, MD4(HMAC), MD5, MD5(HMAC), MD5(Unix), MD5(APR), SHA-1, SHA-1(HMAC), SHA-256, SHA-384, SHA-512, Domain Cached Credentials, Haval-128, Haval-160, Haval-192, Haval-224, Haval-256 and others. The program also supports many complex hashes like md5($pass.$salt), md5($salt.$pass), md5(md5($pass)), etc. Third-party developers had already written modules for PasswordsPro for such types of hashes as MD2, Oracle DES, MS SQL and many others, including hashes no one else program in the world works but PasswordsPro!

Program uses the following methods to recover passwords:

- Preliminary attack;

- Brute-force attack (including distributed attack);

- Mask attack;

- Simple dictionary attack;

- Combined dictionary attack;

- Hybrid dictionary attack;

- Pre-calculated Rainbow-table attack.

PasswordsPro also has the following features:

- Recovery of the passwords up to 127-symbol length;

- Recovery of the passwords for incomplete hashes of any type;

- Editing of users' hashes;

- Search of users' list for required data;

- Quick addition of hash through dialog box;

- Quick check of current password for all hashes in the list;

- Unlimited number of dictionaries used for dictionary attack;

- Unlimited number of tables used for Rainbow-table attack.

Important feature of PasswordsPro it is friendly interface - all hash manipulations are made with literally couple clicks, what makes passwords check very convenient, pictorial and effective.

Another significant advantage of the program is work with Rainbow-tables for any hashing algorithms. These tables can be generated with RTGEN utility of version 1.2. or later. I.e. you can generate tables for SHA-512 algorithm, and PasswordsPro will immediately start working with them.

If you still couldn't find password for your hash, you can always get help at PasswordsPro forum.

Program has Shareware status and is distributed as Demo-version which has the only limitation - number of hashes to import for check is 1, while licensed version doesn't limit this number.

[Review] Fujitsu Lifebook SH530

noreply@blogger.com (GUDANG ILMU) — Mon, 2 May 2011 23:19:00 -0700

Facilities in the Upper Class

Although classified as lower class, this notebook offers top class facilities.
Though relatively well-known brands, Fujitsu is virtually no incentive to bring their notebook products in Indonesia because it is more focused on the European market.

But starting in 2011, they began working on the market poised homeland more serious. This is considering the potential of the mobile computer market here is big enough though it has been crammed with many players. Starting this year, Fujitsu direct even prepare some of their notebooks. One of them with the appearance of most economic models, the LifeBook SH530.
Although classified as entry-level products, Fujitsu is preparing a series SH530 with "dressed" in such a way. This makes it seem as entry-level product. Physical design only uses premium cover (available in 2 colors, namely black and red) that look quite luxurious. It still added the presence of a series of input-output ports are fairly complete.
It seems that Japanese vendors are indeed deliver products that exceed the expectations of the wearer of an economic product. But this economic assumption became faint when I discovered that touching the selling price SH530 Rp8 million figure. What are the advantages?
Basically, the Lifebook SH530 facilities are not much different from the competitors in her class, which sold even more affordable price. But specifically on the I / O, which makes it appear there are additional complete, such as HDMI, eSATA combo port / USB (which can be used to eSATA cable or flash), until the Express Card slot is now just starting rare. Another advantage lies in the structure of the keyboard that can withstand spills of water (water spill-resistant) so it does not go into the mainboard. However, this does not mean the keyboard is water resistant.
Because of its SH530 battery capacity is only 4400 mAh (6 cell) so that the less powerful are used to linger, the notebook weighs 2 kg is included ECO mode. This mode can be activated via a combination of key presses Fn + F11. When both buttons are pressed, the system will go into energy saving mode. When this mode is active, the batteries will be capable of supplying electricity to about 4 hours. However, it should be noted that the activation of this mode will make the performance of the notebook becomes less "ferocious". However, users will still be able to the Internet or simply typing office tasks.
Given the specification (which uses Intel Core 2.4 GHz I3-370M DDR3 memory plus 2 GB and 500 GB hard drive), the performance Lifebook SH530 spelled "is" to conduct daily computing.
Fortunately, the graphics are supported by chip-performing Radeon HD5400 bad for gaming as well as deliver high-definition movies (see comparison table). (Deny Prasetyo)
***
With all the accessories, Lifebook SH530 does offer slightly better value in entry-level class. The price is high raises major question: does this notebook is an entry-level products are priced too high or is a product that is not "sekacangan" a product developed by other competitors? You alone can judge.

Testing Results

Specifications between Glee SW9 Prolink property with SH530 Lifebook very similar and only differ in the graphics chip. Prolink using onboard graphics chip Intel 4500HD. As a result, the performance Lifebook SH530 (based Radeon HD5400) rate is more than Glee SW9. Unfortunately, although the batteries are both 6-cell, the Radeon graphics chip is more power hungry to make use of Lifebook SH530 becomes shorter (except if the ECO mode is activated).

HOW TO MAKE INSTALLER. WINDOWS 7 USING USB

noreply@blogger.com (GUDANG ILMU) — Mon, 2 May 2011 22:48:00 -0700

hi, see you again in this article I want to share with categories Trick, I try to share the knowledge that in fact not new, but it never hurts to learn together. Yes, if there are readers who have a more efficient step-related topics this time. please refer to the complete exposure of both below.
All computer users generally have been doing the installation, either operating systems or applications. When dealing with computers that are still new, of course the user must first install the operating system. Source operating system is usually in the form of a CD or DVD disc. The problem now is, what if the operating system installation will be done on a computer that does not have ODD [Optical Disc Drive]? ODD buy or borrow tools from another computer clearly is not an efficient way.
Departure from these issues, including cross in my mind to make another installer media that media practically available in all types of computers, is a USB [Universal Serial Bus]. Discuss this time I lift the theme making the installer for the operating system Microsoft Windows 7 because it is already widely used today.
Here are some components that must be prepared to make the installer Windows 7 into a flash disk.

1. Execution command to diskpart Login console.

2. Disk list of command execution to see a list of available storage media in the system.

3. Select flash disk that will be used as an installer with the command disk select x [where x is a number that represents your flash disk].

4. Clean the disk with a fill flash net command.

5. Create a primary partition with the command to create a primary partition.

6. Select the partition that was created with the command select 1 partition.

7. Activate the selected partition to active command.

8. Change the NTFS file system type with command format fs = ntfs and wait until the end.

9. Connect flash disk into the system by giving commands. Flash disk will reappear in the command post system.

10. Exit Diskpart console with the command exit.
• Microsoft Windows 7 Sources

Flash is able to accommodate source operating system, please prepare the source of Microsoft's Windows 7 via an optical device or ISO files associated with the system. Next follow the steps below to install the finalization of manufacture.

1. Still from the command prompt window, air factoring into the source directory boot Microsoft Windows 7.

2. Create a boot manager on the flash disk from the source with the command bootsect.exe / nt60 x: [where x is the letter representing the drive flash disk].

3. Back to drive the main source of Microsoft's Windows 7 with the command cd ..

4. Copy the entire contents of the source of Microsoft's Windows 7 to flash disk with the command xcopy / aeh * x [where x is the letter representing the drive flash disk].

How To Help A Struggling Computer?

noreply@blogger.com (GUDANG ILMU) — Mon, 2 May 2011 22:33:00 -0700

If you find your computer struggling with speed, it just means that you need to work out some issues. You might need to increase its Random Access Memory (RAM), tighten up its security to prevent spyware and viruses, and upgrade its parts.
This writer spent most part of last Sunday purging the home computer hard disk of the unused software programs and files. My computer was huffing and puffing through the past couple of weeks, prompting me to use Sunday to work on my system and make it as slim and trim as possible.
I rummaged through all the folders, gleefully pressing the Delete key whenever I found a file unnecessary. Once I got rid of the files, I moved to the Control Panel and began uninstalling the programs which I had never used, nor saw any chance of putting to good use. I wanted to keep the software on my system to a minimum, knowing how unnecessary code just blights a computer's performance.
Once I had taken care of all the bloatware, I waited with anticipation to see the results of my hard work. The computer was as light as air, running as if it was thanking me for taking the load off it.
Yes, the "bloatware" does get hold of the computer, and the first step to push up the speed should be the removal of all that is unnecessary on it. Make it a habit to delete temporary files and useless information before shutting down the system for the day. Run Disk Cleanup and Defragmenter on your system periodically, at least once or twice a month. Using the Disk Cleanup tool frees up space in your hard disk and boosts the PC's performance.
Dust accumulation in your CPU could also slow down the system. If you open up your CPU, you would be shocked to see the amount of dust residing in your machine. Brush away the dust on the motherboard and other critical parts. The dust might also collect on the fan, hampering it from functioning properly. Proper cleaning would help the PC run faster.
Low Random Access Memory (RAM) also withers the computer performance. Each computer application performing in the background is allocated some memory. When all memory is used up, the system becomes unresponsive. In other words, the system gets hanged. You can solve this problem by adding more memory. Additional Random Access Memory becomes even more necessary if you are working with heavier programs such as video editing or photo editing.
You also need to protect your PC from spyware and viruses. Spyware could leak bank account passwords and other sensitive information to anyone sitting at a remote computer. A virus attack could paralyze your system, making working on it impossible. To defend your computer against such attacks, it is important to install reliable anti-spyware and anti-virus programs (and keep them updated). Also, switch on your Windows Firewall to block any attempt of intrusion on your system.
You also need to replace or upgrade computer parts when necessary. You can buy the computer parts at a local hardware store or visit an online shop. You can make your payments using your credit card, and the hardware would be shipped to your office or home, as per your request. Buying computer parts online makes it even more convenient as you have the option to compare products along with their prices and those that provide the best deal.

Do it Yourself to Repair Computer : How To Fix Your PC

noreply@blogger.com (GUDANG ILMU) — Mon, 2 May 2011 22:32:00 -0700

If you are having problems with your computer you can certainly use your DIY techniques to get the machine repaired prior to calling a technician for help. If you're PC starts to display signs of slow processor speed, improper performance or totally crashes down, then its time you get the device back to its peak by following certain basic troubleshooting methods. This is perhaps a suitable alternative that can be adopted before calling an expensive professional for repair and maintenance of your computer.
The chances are that if you happen to contact a pc repair shop or call a troubleshooting helpline, the person whom you address your queries has very little experience. Hence, save yourself the time, effort, expense and inconvenience by simply following some simple steps to get your machine back into action.
Check for Usual Disruptions
The primary check that you can perform when such ordeals take place is to ensure that the cords or cables are plugged in properly. Make sure to check for power fluctuations or failures. If these problems are not applicable in your context, then try restarting the computer or modem.
Probable Alterations or Upgrading
Since, you are the owner of your device; it is inevitable that you know what changes have occurred to your computer of late. It can be the installation of new software or hardware or even the upgrading of existing software. Check for other icons in the system tray to ensure that some program is not running on the background. If a program is present, then simply select the close tab by right clicking over the icon. You can also open the task manager by pressing Ctrl+Alt+ Delete buttons together. End the processes that are running or uninstall the application entirely. If you've recently modified any of the device drivers then simply select and roll back the functionality for windows device drivers.
You can also go to System Configuration utility for an auto-start application. Press the Ctrl + Alt + Del to start off the utility. Try and fix the problems in parts. However, to avoid the system from becoming slow or prevent a non-responsive script, simply turn off all the startup programs by pressing the windows key and "R" key, type msconfig and press enter. You can also choose to restore your computer to an earlier time by following the prompts from the "All Programs" menu.
Switch to a Different Profile
Changing your profile may work for you. Log off the present profile and then log on again from an alternate one. A second user profile may resolve problems with the main account. This can be performed by managing your profiles from the Windows user accounts control panel.
Using Safe Mode to Resolve Issues
This mode is not suitable to fix everything, but it opens Windows with certain basic features. The problems in device drivers are likely to aid in starting Windows in safe mode. Once the problem is known you can use the safe mode to fix it. However, certain issues require a specific driver which is related to your hardware. The windows boot logs can provide detailed information for problems of this kind. Pressing F8 during booting will open the Windows Advanced Options menu which enables the option of boot logging.

The initial step is to choose the type of printer ink you are looking for. It will depend on what purpose you use your printer. For printing plain black text, compatible and remanufactured cartridges will go well. However, branded ink cartridges are the right choice for printing photos and graphics. There are wide ranges of printers available on the market and an even greater range of ink cartridges.
As reputed printer manufacturers like Hewlett Packard, Epson, Lexmark, Apple etc. make up a new printer they bring along with printer ink to go with them.
Gluts of printer suppliers have their websites providing arrays of ink cartridge. When shopping for your printer ink online, it is however recommended that you make a good search by visiting at least five to six times prior making a deal.
The suppliers are highly commercial and they offer various prices to earn profit from per product they sale. You need to keep a hawk eye paying visits to different websites, comparing the rates and discounts (if any) and then place the order for your printer needs. Online shopping is best in its way as it offers cheaper prices of products than those at the retail stores. For a lucrative deal, you can visit websites offering cartridges from various manufacturers because this way you can easily compare the prices and can choose the best one for you.
What most people hesitate when shopping online is that they could not get the firsthand look at the product!
But those who believe to make pre-shopping investigation can go with online process blindfolded as reputed dealers over the net offer only guaranteed and secured service.

OEM (Original Equipment Manufacturer) toners come out from the house of professional printer manufacturers and they go well only with particular printer models. They carry a brand logo which guarantees their superiority of quality. However, OEM toners are expensive and can be a bit much for users running on a shoe string budget.
On the other hand, remanufactured toners are made by third-party manufacturers using the brand new OEM parts. They serve as a great alternative to OEM cartridges because they are customized for meeting the equivalent standards for OEM cartridges at a cheaper price.
