4. Search on Google for the Tahoma font with the following string:

tahoma filetype:ttf

Save it on your desktop, then move it to the Wine fonts folder (full path -> /home/yourusername/.wine/drive_c/windows/fonts).

Tip: To see the .wine folder, go to View -> Show Hidden Files option in your home directory.

Step 2: Install Photoshop CS2

Insert your Photoshop CS2 CD in the optical drive and a folder should appear after a few seconds. Go to the "Adobe Photoshop CS2" directory, right click on the setup.exe file and choose the Open with "Wine Windows Emulator" option. The Photoshop installer will pop-up and I guess you know what to do now.

How To: Install Windows 7/Vista From USB Drive

courtesy : www.intowindows.com

This guide works 100% for Vista & Windows 7 unlike most of the guides out there. I have seen many sites/blogs that have “Install Vista from USB guide” but either with incomplete steps or not working guide. I have also seen some guides that don’t’ use proper commands in this guide. After spending many hours I have come up with this 100% working guide.

Bootable USB drive

I just did this method on one of my friends machine and installed the new Windows 7 BETA. The main advantage is that by using USB drive you will be able to install Windows 7/Vista in just 15 minutes. You can also use this bootable USB drive on friend’s computer who doesn’t have a DVD optical drive.

The method is very simple and you can use without any hassles. Needless to say that your motherboard should support USB Boot feature to make use of the bootable USB drive.

Requirements:

*USB Flash Drive (Minimum 4GB)

*Windows 7 or Vista installation files.

Follow the below steps to create bootable Windows 7/Vista USB drive using which you can install Windows 7/Vista easily.

1. Plug-in your USB flash drive to USB port and move all the contents from USB drive to a safe location on your system.

2. Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt with admin rights.

*Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.

Or

*Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.

3. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:

First type DISKPART and hit enter to see the below message.

Bootable USB Drive

Next type LIST DISK command and note down the Disk number (ex: Disk 1) of your USB flash drive. In the below screenshot my Flash Drive Disk no is Disk 1.

4. Next type all the below commands one by one. Here I assume that your disk drive no is “Disk 1”.If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it.

So below are the commands you need to type and execute one by one:

SELECT DISK 1

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS

(Format process may take few seconds)

ASSIGN

EXIT

Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

Bootable USB Drive

5. Next insert your Windows7/Vista DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about it).

6. Maximize the minimized Command Prompt in the 4th step.Type the following command now:

D:CD BOOT and hit enter.Where “D” is your DVD drive letter.

CD BOOT and hit enter to see the below message.

7. Type another command given below to update the USB drive with BOOTMGR compatible code.

BOOTSECT.EXE/NT60 H:

14

Where “H” is your USB drive letter. Once you enter the above command you will see the below message.

8. Copy your Windows 7/Vista DVD contents to the USB flash drive.

9. Your USB drive is ready to boot and install Windows 7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.

Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB. If you got any problem in following this guide feel free to ask questions by leaving comment.

How To Make Bootable USB

courtesy : www.intowindows.com

Having a bootable USB is very essential, especially if you are a Netbook user. Using bootable USB to install an operating system (OS) not only makes the installation faster, but also saves a DVD.

Creating or using an USB drive to install Windows operating systems is very easy if you follow the below mentioned steps.

bootable usb drive

If you are planning to use bootable USB to install Windows 7 or Vista please refer our guides:

Install Windows 7/Vista using bootable USB guide

And also, you can refer install Windows 7 on Acer Aspire One guide

Coming back to bootable USB guide, here we assume that you are using either Vista or Windows 7 to create a bootable USB.

1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable.

2. Open elevated Command Prompt. To do this, type in CMD in Start menu search field and hit Ctrl + Shift + Enter. Alternatively, navigate to Start > All programs >Accessories > right click on Command Prompt and select run as administrator.

3. When the Command Prompt opens, enter the following command:

DISKPART and hit enter.

LIST DISK and hit enter.

Once you enter the LIST DISK command, it will show the disk number of your USB drive. In the below image my USB drive disk no is Disk 1.

4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do.

SELECT DISK 1 (Replace DISK 1 with your disk number)

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS

(Format process may take few seconds)

ASSIGN

EXIT

Bootable USB

Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use “D” as my optical (DVD) drive letter and “H” as my USB drive letter.

6. Go back to command prompt and execute the following commands:

D:CD BOOT and hit enter. Where “D” is your DVD drive letter.

CD BOOT and hit enter to see the below message.

BOOTSECT.EXE/NT60 H:

(Where “H” is your USB drive letter)

USB Bootable

7. Copy Windows DVD contents to USB.

You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).

Note that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.

How does anti-virus software work?

An anti-virus software program is a computer program that can be used to scan files to identify and eliminate computer viruses and other malicious software (malware).

Anti-virus software typically uses two different techniques to accomplish this:

  • Examining files to look for known viruses by means of a virus dictionary
  • Identifying suspicious behavior from any computer program which might indicate infection

Most commercial anti-virus software uses both of these approaches, with an emphasis on the virus dictionary approach.

Virus dictionary approach
In the virus dictionary approach, when the anti-virus software examines a file, it refers to a dictionary of known viruses that have been identified by the author of the anti-virus software. If a piece of code in the file matches any virus identified in the dictionary, then the anti-virus software can then either delete the file, quarantine it so that the file is inaccessible to other programs and its virus is unable to spread, or attempt to repair the file by removing the virus itself from the file.

To be successful in the medium and long term, the virus dictionary approach requires periodic online downloads of updated virus dictionary entries. As new viruses are identified "in the wild", civically minded and technically inclined users can send their infected files to the authors of anti-virus software, who then include information about the new viruses in their dictionaries.

Dictionary-based anti-virus software typically examines files when the computer's operating system creates, opens, and closes them; and when the files are e-mailed. In this way, a known virus can be detected immediately upon receipt. The software can also typically be scheduled to examine all files on the user's hard disk on a regular basis.

Although the dictionary approach is considered effective, virus authors have tried to stay a step ahead of such software by writing "polymorphic viruses", which encrypt parts of themselves or otherwise modify themselves as a method of disguise, so as to not match the virus's signature in the dictionary.

Suspicious behavior approach
The suspicious behavior approach, by contrast, doesn't attempt to identify known viruses, but instead monitors the behavior of all programs. If one program tries to write data to an executable program, for example, this is flagged as suspicious behavior and the user is alerted to this, and asked what to do.

Unlike the dictionary approach, the suspicious behavior approach therefore provides protection against brand-new viruses that do not yet exist in any virus dictionaries. However, it also sounds a large number of false positives, and users probably become desensitized to all the warnings. If the user clicks "Accept" on every such warning, then the anti-virus software is obviously useless to that user. This problem has especially been made worse over the past 7 years, since many more nonmalicious program designs chose to modify other .exes without regards to this false positive issue. Thus, most modern anti virus software uses this technique less and less.

Other ways to detect viruses
Some antivirus-software will try to emulate the beginning of the code of each new executable that is being executed before transferring control to the executable. If the program seems to be using self-modifying code or otherwise appears as a virus (it immeadeatly tries to find other executables), one could assume that the executable has been infected with a virus. However, this method results in a lot of false positives.

Yet another detection method is using a sandbox. A sandbox emulates the operating system and runs the executable in this simulation. After the program has terminated, the sandbox is analysed for changes which might indicate a virus. Because of performance issues this type of detection is normally only performed during on-demand scans.

Issues of concern

Macro viruses, arguably the most destructive and widespread computer viruses, could be prevented far more inexpensively and effectively, and without the need of all users to buy anti-virus software, if Microsoft would fix security flaws in Microsoft Outlook and Microsoft Office related to the execution of downloaded code and to the ability of document macros to spread and wreak havoc.

User education is as important as anti-virus software; simply training users in safe computing practices, such as not downloading and executing unknown programs from the Internet, would slow the spread of viruses, without the need of anti-virus software.

Computer users should not always run with administrator access to their own machine. If they would simply run in user mode then some types of viruses would not be able to spread.

The dictionary approach to detecting viruses is often insufficient due to the continual creation of new viruses, yet the suspicious behavior approach is ineffective due to the false positive problem; hence, the current understanding of anti-virus software will never conquer computer viruses.

There are various methods of encrypting and packing malicious software which will make even well-known viruses undetectable to anti-virus software. Detecting these "camouflaged" viruses requires a powerful unpacking engine, which can decrypt the files before examining them. Unfortunately, many popular anti-virus programs do not have this and thus are often unable to detect encrypted viruses.

Companies that sell anti-virus software seem to have a financial incentive for viruses to be written and to spread, and for the public to panic over the threat.

How To Trace An Email

What is an email header?

Each email you receive comes with headers. The headers contain information about the routing of the email and the originating IP of the email. Not all emails you receive can be traced back to the originating point and depending on how you send emails determines whether or not they can trace the email back to you. The headers don't contain any personal information. At most, you can get the originating IP and the computer name that sent the email. The originating IP can be looked up to determine from where the email was sent. IP address location information DOES NOT contain your street address or phone number. It will most likely determine the city and the ISP the sender used.

How do I get the email header?

Each email program will vary as to how you get to the email options.

  • Outlook

Right click the email while it's in the inbox and choose Message Options. A window will open with the headers in the bottom of the window.

  • Windows Live Mail

Right click the email while it's in the inbox, choose Properties, then click the Details tab.

  • GMail

Open the email. In the upper right corner of the email you'll see the word Reply with a little down arrow to the right. Click the down arrow and choose Show Original.

  • Hotmail

Right click the email in the inbox and choose View Message Source.

  • Yahoo!

Right click the email in the inbox and choose View Full Headers.

You can see that no matter the email program, the headers are usually just a right click away.

I've got the header, now what?

Usually the first IP listed is where the email originated. There are exceptions to this. You'll have to look at the information logically to deduce the originating IP.

Can any email be traced?

Yes and No. For example, someone who sends an email to your hotmail account shows in the X-Originating IP section of the headers. However, someone who sends you an email from GMail can ONLY be traced back to the GMail servers.

Samsung USB DVD-Burner

If you have a netbook or ultraportable laptop, chances are it doesn't have an internal optical drive. While most users will stick with the same operating system and setup for the life of the computer, some might want to

restore or even upgrade to a newer configuration. This is where an external USB optical drive comes into play. Look at the Samsung SE-S084 tray-loading DVD-burner, and find out how well it works on with multiple systems.




Samsung SE-S084 Specifications:

  • Write Speeds: 8x DVD, 24x CD
  • Interface: USB 2.0
  • Buffer memory: 2MB
  • Supported Media: DVD-RAM, DVD+R, DVD+R DL, DVD+RW, DVD-R, DVD-R DL, DVD-RW, DVD-ROM, DVD-Video, CD-R, CD-RW, CD-ROM/XA, CD-ROM, CD-Audio, Video-CD, CD-1 (FMV), Photo CD, CD-Extra, CD-TEXT
  • Weight: .4kg
  • Dimensions: 141x19x157mm
  • MSRP: $69.99 (Street price: $59.99)

Build and Design The Samsung SE-S084 has a box-like shape with a glossy painted top and dark-grey trim. The color scheme goes well with the Samsung N110 shares the same tone of glossy black paint and matched logo. I would have been more impressed with the design if Samsung moved to a more rounded look like the design of the HP Pavilion dv2's drive, but that is just personal preference.


Samsung SE-S084


HP Pavilion dv2z external optical drive

The external drive feels solid, with no creaks or squeaks the the plastic when you squeeze the covers around the internal drive. Flex is minimal and it should hold up very well when carried in a travel bag with other heavy items. The mini-USB jack on the back of the drive appears to be designed to reduce stress from the cable with the connector fitting into a recessed hole. An integrated cable would have been even better, but if you use the drive frequently it is nice knowing that the cable can be swapped out if it ever becomes damaged.

In Use No drivers needed to be installed on any of the notebooks and netbooks we tested the drive with in order for it to be recognized. This included Windows XP, Vista, and Windows 7, which all supported writing files to the drive with a blank disc ready and waiting. We tested the drive with the included Nero Essentials software, as well as ISO Recorder to burn MSDN provided ISOs to test various operating conditions.


In our testing, we used a Dell Latitude D630 as our full-size notebook and the 10" Samsung N110 to be our netbook candidate. Each test consisted of burning an ISO to the drive, with a single USB connection, or with the Y-connector, while the computer operated off of battery power. In each test case the ISOs burned in approximately the same time, and we never ran into problems using just a single USB connection. Each DVD image was 2.33GB, and it took just over three minutes to start the burn, finalize, and eject the disc. Samsung does warn users in the product manual that some machines may not provide enough current over a single USB port to adequately operate the drive, but in our office we didn't run into this problem.

Conclusion The Samsung SE-S084 is a nice compact USB DVD-burner that works well with notebooks and netbooks. The design might not be as refined as some of the other USB optical drives on the market, but it does its job as intended, and works with basically any Windows XP or Windows Vista machine. While Samsung does warn that some computers may not supply enough power to operate the drive using a single USB connector, we found the drive to work just fine on notebooks and netbooks around the office. Overall for $60, if you don't already have an external drive it is a great accessory to add to your bag.

Pros:

  • No drivers needed on most notebooks and netbooks
  • Good looking paint
  • Matches the look of Samsung netbooks
  • Built-in USB stress reliever

Cons:

  • Cable isn't integrated
