Puppy Linux-Maria Skambili Deryneia Famagusta Cyprus

Puppy Linux has been built from the ground up but can be rebuilt, "based" on other distros using a special script tool "woof".

Puppy GNU/Linux is very small - typically about 120MB. 

Puppy is designed to be loaded entirely into RAM and ran from there.Puppy is designed to take up a certain percentage of ram, so it typically doesn't load that entire size, so you can run puppy on a machine with very little ram.

Puppy is designed to run entirely out of memory, so it will typically load itself into RAM when you boot, this usually means a slower boot time but it will mean accessing your files and programs will be considerably quicker as they are being accessed via RAM.

This also means you can run puppy on a machine that does not have a hard drive.

Puppy is actually designed to run live, so it is actually not recommended to install it at all. It can be ran from a CD or a USB and can save back to either format (even CD-R). If you do wish to install it to the HDD there is a graphical script you can use called "Puppy Universal Installer.

Puppy can also be built to be compatible with any other packages, currently the "main" puppys are:
  • Lucid: based on Ubuntu
  • Slacko: based on Slackware
  • Wary: built from the ground up to be as compatible as possible with all hardware
  • Racy: built from the ground up, using the latest Linux kernel to work best with the latest hardware

Copying files over 4GB to a USB flash drive-Maria Skambili Deryneia Famagusta Cyprus

You have an external drive with capacity  8GB, 16 GB and more. You try to copy large files over 4GB to a USB flash drive but an error shows up such as "There is not enough free space on the drive" even though there is enough free space in your external drive. If you experience such a problem, is probably because that your flash drive is formatted with the FAT32 file system

How to solve the problem of copying the 4GB files?

You need to replace the FAT32 file system on the drive with the NTFS file system. It does not have the 4GB file size limitation, and it also allows for many other functions not supported by FAT32: file security, encryption, compression, etc.

However: the older versions of Windows ( Windows 95, 98, or Windows Millennium) do not support the NTFS file system. If you plan on using the drive with old computers, then DO NOT format the drive with NTFS, because you won’t be able to get the old Windows to recognize it anyway. However, if you only plan on using the drive with the more recent versions of Windows(Windows 2000, Windows XP, Windows Vista, Windows 7) you can use the NTFS file system.


How to change the drive from FAT32 to NTFS format?

There are several ways to go. If the drive is empty or contains no important files of yours, the easiest way is to use the Windows Format command to format the drive with the NTFS file system.

Specifically:
1. Attach the external flash drive to the computer, wait for Windows to recognize it.
2. Open the Computer folder and locate the drive letter assigned to the flash drive you want to format with NTFS (in the example below, it’s drive F:)
3. Before continuing, open the drive in a window and make sure it’s empty or does not contain any important files, because after you format a drive, all information that was on it will be erased!
4. If you are sure that the external drive contains no important files of yours, go back to the Computer folder, and right click on the icon of the external drive.
 Windows offers the Format command on the shortcut menu

5. Select Format from the menu, and then choose the formatting options:
Options for formatting the external drive with NTFS file system
6. Make sure to select NTFS in the File System drop-down list. That’s what determines the kind of a file system that the drive should have. Also, you may want to select the Quick Format option, which should speed up the formatting process quite considerably.
7. Press Start, and Windows should warn you once again about erasing any existing information on the drive.

As a result, you should have the same drive, but now it should have the NTFS files system on it. Now you should be able to copy the files larger than 4GB to the drive just fine.

In addition to formatting a drive with the NTFS file system, Windows also offers a way to convert a FAT32 drive to NTFS. The difference is that with this conversion process the existing files on the drive are not erased.

Email Etiquette-Maria Skambili Deryneia Famagusta Cyprus

Inadequate grammar, poor spelling, and bad taste. Consider what impressions your emails make on others. Follow these steps and improve your email etiquette.

Steps

  1. Keep your email concise, conversational, and focused. Keep emails short and to the point. Many people only read the first few lines before deciding to respond or to save for later.
  2. Avoid fancy formatting.
  3. Limit attachments. Don't add an attachment unless really necessary. Keep attachments as small as possible. If you need to send a larger file, compress or zip it or use online services that will help you send large files such as WeTransfer.com. If you need to send multiple pages, such as meeting plans or large text corrections, send a fax or a typed set of pages in a letter.
  4. Think before you send.  Only add the recipients and send it after you have had time to think about what you are sending; you might change your mind and be better off for it.
  5. Be careful using abbreviations and emoticons.
  6. Avoid prioritizing your messages for the recipient. Get out of the habit of marking every email as "Urgent!” or "High Priority"
  7. Summarize long discussions. Instead of continuing to forward a message string, take a minute to summarize it for your reader.
  8. Be sure to include info that you are responding to. Include the question that the recipient asked so they know what you are responding to. Avoid making the recipient scroll down more than a single message in the history.
  9. Reply promptly.
  10. Be proactive. Address reader's  questions or concerns in your reply before somebody has to send a new email to ask about them.

Image editing softwares: GIMP Vs Photoshop-Maria Skambili Deryneia Famagusta Cyprus

In Linux community GIMP is used for image editing since Photoshop is not available for Linux users.

GIMP is an abbreviation and stands for "GNU Image Manipulation Program (GIMP)". It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages.

Some say "use Gimp for image editing"or  "Gimp is a Photoshop alternative". Some even dare to say that "Gimp is a Photoshop substitute". But how well these statements are true? Below there is comparison between Gimp and Adobe Photoshop in five major areas.

  Gimp Vs Photoshop

1. The price: Gimp is open source software so it is free. In contrast Photoshop costs $642.58 on Amazon.com or $19.99/month through Adobe Creative Cloud at this time.
2.OS  Compatibility: GIMP is cross-platform. You can use GIMP on Mac, Windows, as well as Linux. Photoshop is not available for Linux users.
3. Hardware Requirements: In terms of hardware requirements, such as RAM requirements and disk space consumed, GIMP needs less hardware resources than Photoshop.
4. Features:In terms of features, Photoshop clearly has way more features than GIMP.
That said, GIMP also has a more than just decent set of features, and the community keeps producing one awesome plugin for GIMP after another.
5.  Easy to use: On the downside, GIMP is notorious for having a steep learning curve. Gimp user interface is not the same as Photoshop user interface , so new users might find it to be quite confusing and difficult to use. 

Conclusion:

I personally love GIMP and i  use it for my everyday image editing needs but it can not compete the powerful and almighty Photoshop. We cannot overlook the fact that Photoshop is, indeed, the industry-standard when it comes to image authoring and editing. Just because I can use or afford  Photoshop that doesn't make GIMP a Photoshop alternative.
