We’ll start with cursor control, as it’s the first need when you open a file.

h Left
j Down
k Up
l (or spacebar)    Right

Of course, you’re welcome to use keyboard arrows if you like them so much. There are some more complicated manipulations, so let me show them. These commands will help you to navigate between your file text in a smart way.

w Forward one word
b Back one word
e End of word
( Beginning of current sentence
) Beginning of next sentence
{ Beginning of current paragraph
} Beginning of next paragraph
[[ Beginning of current section
]] Beginning of next section
0 Start of current line
$ End of current line
^ First non-white character of current line
+ or Return (Enter)    First character of next line
- First character of previous line
n | character n of current line

If your file takes some screens, there are some commands for screen movements.

H Top line of current screen
M Middle line of current screen
L Last line of current screen
nH n lines after top line of current screen
nL n lines before last line of current screen
Ctrl-F Forward one screen
Ctrl-B Back one screen
Ctrl-D Down half a screen
Ctrl-U Up half a screen
Ctrl-E Display another line at bottom of screen
Ctrl-Y Display another line at top of screen
z Return (Enter)  Redraw screen with cursor at top
z . Redraw screen with cursor in middle
z – Redraw screen with cursor at bottom
Ctrl-L Redraw screen without re-positioning
Ctrl-R Redraw screen without re-positioning

Of course, there are some commands related to search and moving between line numbers.
/text Search for text (forwards)
/    Repeat forward search (Just like F3 in Microsoft Windows)
?text Search for text (backwards)
? Repeat previous search backwards
n Repeat previous search
N Repeat previous search, but it opposite direction
/text/+n    Go to line n after text
?text?-n Go to line n before text
% Find match of current parenthesis, brace, or bracket (very useful for programmers).
Ctrl-G Display line number of cursor
nG Move cursor to line number n
:n Move cursor to line number n
G Move to last line in file

As you can see, there are lots of ways to navigate within a file. Let’s start with wile editing commands, they aren’t less interesting.

A Append to end of current line
i Insert before cursor
I Insert at beginning of line
o Open line above cursor
O Open line below cursor
ESC End of insert mode
Ctrl-I Insert a tab
Ctrl-T Move to next tab position
Backspace Move back one character
Ctrl-U Delete current line
Ctrl-V Quote next character
Ctrl-W Move back one word
cw Change word
cc Change line
C Change from current position to end of line
dd Delete current line
ndd Delete n lines
D Delete remainer of line
dw Delete word
d} Delete rest of paragraph
d^ Delete back to start of line
c/pat Delete up to first occurance of pattern
dn Delete up to next occurance of pattern
dfa Delete up to and including a on current line
dta Delete up to, but not including, a on current line
dL Delete up to last line on screen
dG Delete to end of file
J Join two lines
p Insert buffer after cursor
P Insert buffer before cursor
rx Replace character with x
Rtext Replace text beginning at cursor
s Substitute character
ns Substitute n characters
S Substitute entire line
u Undo last change

And we finally come to file manipulation commands as we will need to save (or not) our changes.

:w Write file
:w! Write file (ignoring warnings, force writing)
:w! file Overwrite file (ignoring warnings)
:wq Write file and quit
:q Quit
:q! Quit (even if changes not saved)
:w file Write file as file, leaving original untouched
ZZ Quit, only writing file if changed
Quit, only writing file if changed
:n1,n2w file Write lines n1 to n2 to file
:n1,n2w >> file Append lines n1 to n2 to file
:e file2    Edit file2 (current file becomes alternate file)
:e! Reload file from disk (revert to previous saved version)
:e# Edit alternate file
% Display current filename
# Display alternate filename
:n Edit next file
:n! Edit next file (ignoring warnings)
:n files Specify new list of files
:r file Insert file after cursor
:r !command Run command, and insert output after current line

As you can see, the number of vi commands is really huge. If you get acquainted to this editor, you won’t even try anything else, the professional programmers say. If you need vi to edit files (e.g. crontab modification), you will find all the necessary commands above.

Have a good time with vi!

One of the greatest things about WordPress, in addition to the fact that it’s absolutely free, is the feature of being completely customizable, thus giving the opportunity to use it for almost anything.

Since the appearance of the first version (0.7 on 27th of May, 2003) WordPress has been constantly updated introducing a lot of different improvements and offering greater functionality each and every time. Starting from the Version 1.0 most of the releases were named after well-known jazz musicians. After 1.5 release WordPress seemed to have something people really liked and it started to experience some fairly rapid growth (in a period of one year – from 2006 to 2007 – the amount of downloads increased in more than 2,5 times).

The last version – 2.8 “Baker” version named in honor of noted trumpeter and vocalist Chet Baker – representing the main topic of the given post was released on June 10th, 2009. Let’s check what new features and improvements of this release are.

“Baker” version of WordPress is a finish release with a significant amount of improvements to widgets, themes and speed. Despite the fact that at the very beginning you may notice just some minor changes, especially as regards the overall design, soon you will be able to find out much more. Altogether there are over 180 new features, changes, upgrades, and improvements (you can check the full list here); moreover it’s said that more than 790 bugs were fixed.

So let’s mention the most important improvements (or you can skip it and watch the video if you don’t like reading much )

1. Speed: WordPress became significantly faster to use because of changing the way it does style and scripting.
2. Changing themes: now you can install a theme with a single click from the admin
3. Screen Options: there are new Screen Options on every page giving you the opportunity to rearrange the items (you can have a special look for each of the pages). The dashboard widgets can be arranged in up to four columns
4. CodePress editor: now the syntax highlighting is integrated ensuring much better experience of editing the code of themes or plugins
5. Widget user interface: a way better (redesigned) widgets interface allowing you to edit widgets on the fly, have multiple copies of the same widget, drag and drop widgets between sidebars, and save inactive widgets so you don’t lose all their settings. Additionally developers now have access to a much cleaner and robust API for creating widgets as well.
6. Comments: separating Comments into a separate postbox, from Discussion postbox, on the Edit Post screen; no more notifying post author of own comments; no asking for confirmation when marking a comment as spam
7. and many others…

Here is the video about te abovementioned improvements:

There is also another nice point that should be emphasized… Due to the improvent that was intorduced in 2.7 version, now it’s much easier to update WordPress (the process is simplified into just a few clicks!!!). However you have to be carefull and don’t forget to backup your block as prompted when going trough the upgrade process. There is hardly a significant time difference, but it’s much safer for you to know that nothing will happen to your blog.

As a result I would like to mention that according to developers’ words they “are already thinking hard about the next versions, 2.9 and 3.0”. As regards the improvements which will probably be made, here are some of them: “media hanling, better dependency checking, versioning of templates and themes, and of course the fabled merging of WordPress and MU announced at WordCamp San Francisco”.

A credit card processing service represents a company which processes credit card transactions for the retail, wholesale, mail order, phone, and Internet trades. Such companies handle the multiple steps involved in credit card processing in exchange for a fee (usually a certain percentage of each transaction). If you want to be able to accept credit cards then finding a credit card processing service to deal with is especially vital.

Let’s take a closer look at how Online Credit Card Processing works…

• Customer finds the merchant’s site and chooses the products to buy. When he/she is ready to go ahead with the purchase, he/she enters their credit card information.
• In case the merchant does not have a secure page, the customer will be transferred to a secure payment gateway. If the merchant does have a secure site, then the information will be “passed” to the payment gateway without the customer ever leaving the merchant’s site.
• As soon as the credit card info is introduced the payment gateway transfers it to CCPS.
• The processing service transfers the information from the online payment gateway to the bank that issued the credit card, which verifies if the card is valid and has the requested amount on it.
• The bank (credit card issuer) sets aside the purchase amount for the merchant and sends back an approval number or a decline message to CCPS.
• It takes just 3-15 seconds for the information in steps 2-6 to be passed back to the gateway.
• The payment gateway sends the approval code to the merchant’s site or, if the merchant does not have a secure site, gives the customer their approval information. At this point the merchant can email the customer a payment receipt.
• Final payment is secured and is deposited in the internet merchant’s account. Generally it takes two business days for the funds to reach the merchant’s checking account.

At the moment there are so many CCP Companies that it’s really hard to determine which one is the best for your business.

Thus the purpose of this post-review is to make your decision a little bit easier for you. There are a few things you need to take into consideration when choosing a Credit Card Processing Service:

• Average approval rating (the number of people that applied divided by the number of people actually approves)
• All types of fees and their amount you need to pay
• Good customer service (24/7 support, different ways of reaching the customer support service: telephone, email or instant messaging)
• Fraud and security protection.

At this point you should know enough about the Credit Card Processing Services to be able to compare them. So let’s go ahead with the comparison…

49 ¹ – this is just one time set up fee of $49.00. There are no leases, no monthly fees, no application fees, no gateway fees, no additional card company or third party charges and no statement fees.

I’m more than sure that now it’s much easier for you to make your final decision.
