This article is for us old school types. Midnight Commander is a great file manager. Features include an ftp client, a file viewer, and a file editor. While the online file viewer and file editor are good but if you want use a different command line text editor you can configure midnight commander to use it. In this example to I will use vim and Ubuntu.

1. Select Configuration under the options menu in Midnight Commander.
2. Deselect use internal edit and use internal view.
3. Save your changes
4. At the command line run $sudo update-alternatives --config editor
5. Select Vim from list
7. Add the following lines to your .bashrc
• EDITOR=/usr/bin/vim
• export EDITOR=/usr/bin/vim

Now when you select edit or view in MC Vim should start.

When you take a photo with your digital camera most often that image is too large for your website.

Today you can buy a 10 megapixel camera for $80 and that camera will produce a picture with an average file size of 2.2 Megabytes. You certainly don't want to load your website with pictures that large. The smaller the file size the better as far as the web is concerned. The maximium size in most cases should be no larger then 100 kilobytes.

The question becomes how do you shrink the picture down in size? I use two different programs to manupulate images. The first is GIMP which is an Opensource alternative to Photoshop. Gimp is a great program and if you need to do image manipulation you should have this program. Gimp is great working with a few photos but if I have 50 pictures I need to shrink down for a website I prefer ImageMagick.

ImageMagick is a command-line program that allows you to convert or manipulate images and works great for converting a large number of pictures. Once the right command is entered and the return key is entered, ImageMagick happily processes the photos with no more input from the user. ImageMagick is fairly quick but quick can be a relative term. Imaging processing is a heavy cpu process so it may take some time so once the process starts go get a cup of coffee.

There are two commands you will use with ImageMagick one is convert and the other is mogrify. Both commands change images convert is usually considered safer because it takes the old image, changes the image, and saves the new image with a new name but be warned you can destroy the old image if you make the new name the same as the old. mogrify takes the images and converts it so the original is gone and the new image takes it place. There is a path option that prevents this behavior but you are new to the program so do you really trust yourself. The first time I used the path option I did it wrong and mogrify happily ate the original image. So what is the point of this paragraph? Always, Always, did I say Always work on a copy of your pictures, ImageMagick will happily do what you tell it and if you tell it to eat your originals it will.

Here is a mogrify batch command to change the image resolution to 72 dpi and set the quality to 80% on all jpeg files in the current directory and save them in the directory /home/frrobert/Pictures/testmagik Warning if the specified directory does not exist ImageMagick will happily do it in the current directory.

mogrify -resample 72 -quality 80% -path /home/frrobert/Pictures/testmagik *.jpg

What! Lets dissect that command

mogrify

-resample 72

-quality 80%

-path /home/frrobert/Pictures/testmagik

*.jpg

Here is a convert batch command to change the image resolution to 72 dpi and set the quality to 80% on all jpeg files in the current directory and save them in the current directory with a new file name with the prefix SM plus the original file name Example: picture.jpg become SMpicture.jpg

convert *.jpg -resample 72 -quality 80% -set filename:orig %t  SM%[filename:orig].jpg

Lets dissect this command.

convert

*.jpg

-resample 72

-quality 80%

-set filename:orig %t

SM%[filename:orig].jpg

One of the questions is why hire a freelancer to do your web design?  I think the simplest answer is flexibility and cost efficiency.

As a freelancer I have a great amount of flexibility in what type of services I can provide.

You maybe a large company with an IT department but just need an extra person for a few months to work on an Intranet site for maintenance work orders.

You may be a web design company owner that needs a developer to assist with a technical aspect of project for one of your customers that is not in your knowledgebase.

Developing a relationship with a freelancer expands the knowledge base of your company but avoids the cost associated with an traditional employee. Need a programmer for a project that lasts 2 weeks but you don't need them till the next programming project comes through the door. A freelancer can be the answer. Keeping an employee on staff for an occasional need is not cost effective but using a freelancer is. You pay a freelancer when you need them but don't pay them when there is no need.

A freelancer gives your company the flexibility to work on projects that may exceed your current knowledgebase in a cost effective manner.
