Editing files with vi

https://www.control-escape.com/linux/editing-vim.html

The thing you have to understand about vi and its work-alike editors is modality. Most programs have just one mode, accepting input and placing it at the cursor. This is what you probably expect from a program. But vi has other modes. When you start vi, you’ll be in “Normal” mode, which is really command mode. When you are in Normal mode, whatever you type is considered not to be input, but commands that vi will try to execute.

This may sound a little crazy, but it is actually a very powerful way to edit documents. Even if you hate it, the ubiquity of vi means that you’re going to need to learn the basics, because sometimes you just have to use it. On the other hand, if you enjoy working at a command line, then you may end uploving vi.

Lesson 1: How to Quit vi

Since vi is the default editor, there’s a good chance you got dropped into it without knowing it. This can be extremely frustrating if you don’t know your way around the program.

To exit vi without saving changes, hit Escape a couple of times to ensure you are in Normal mode, and then type:

:q!

Lesson 2: Editing with vi

Start vi and press i. The cursor may change shape, and INSERT is displayed at the bottom of the screen (in most vi clones). You are now in insert mode — all your keystrokes are entered into the current buffer and are displayed to the screen.

Hit the Escape key. The cursor changes shape again, and INSERT has disappeared. You are back in Normal mode. Hitting Escape a few times will pretty much always cancel whatever you are doing and return you to Normal mode.

Command mode is also where you move around in the file. On most systems, you can use the arrow keys to move the cursor. If that fails, cursor movement can be accomplished with the hjkl keys:

h   move left one character
j   move down one character
k   move up one character
l   move right one character

vi has its own command line, which you access by typing a colon. Commands typed at the command line will not be executed until you hit Enter, just like in the shell.

Many of the commands that you will use in command mode begin with a colon. For example, the command to quit is :q, as we learned in Lesson 1 above. Actually, in Lesson 1 we added !, which tells vi to “force” the operation. If you have edited the file, typing :q will not immediately exit the program, but instead produce this error message:

E37: No write since last change (add ! to override)

To save your changes, use the :w command (“Write”). You can save and quit all in one go by typing both commands together:

:wq

Of course, if you started vi without giving a file name, you’ll need to provide one. For example, to save your working file as test.txt, you would type:

:w test.txt

Try editing some text now.

• Start vi
• Hit i to go to Insert mode.
• Type some text.
• Hit Escape to return to Normal mode.
• Type :w test.txt to save your work
• Type :q to quit

How to Fix SSL Error When You Can’t Login to WordPress

http://www.beginwp.com/solve-ssl-error-login-issues-wordpress/

Errors and problems are something that we all face them sooner or later. However, these errors should not prevent us from trying or experimenting with something new. One of the strange issue that many users face is that when trying to login to WordPress, an SSL error is occurred. In this post, you’re going to learn how to fix SSL error when you’re unable to login to WordPress admin (or Dashboard).

So let’s take a look at all these SSL related problems in WordPress, along with their solutions.

SSL certificate

Have you recently activated SSL certificate on your site and are unable to login to WordPress? In such a case, ensure that you’ve correctly configured SSL certificate and settings related to it. Improperly configured SSL certificate may cause login issues.

Edit your wp-config.php file

Some users make changes in: Settings > General, and update WordPress Address (URL) and Site Address (URL) from there. By mistake, you might have added HTTPS to the URL. For example; https://yoursite.com instead of http://yoursite.com

If you’ve made these changes, then you won’t be able to login to WordPress. That’s why, you’ll now need to use a FTP client like Filezilla, or use your cPanel’s File Manager and edit your wp-config.php manually. Add these lines to your wp-config.php

define(‘WP_HOME’,’http://example.com’);
define(‘WP_SITEURL’,’http://example.com’);

Add these lines just before:

/* That’s all, stop editing! Happy blogging. */

Also replace example.com with your own domain name.

Check your .htaccess file

In your site’s root directory, such as domain.com/public_html, you’ll find a file named as .htaccess. In some cases, it might be hidden and you’ll need to checkmark “view hidden files” in the cPanel’s File Manager.

Ensure that your .htaccess looks like below:

?

1 2 3 4 5 6 7 8 9 10 11

# BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress

If it doesn’t looks like this, then edit it and make the required changes.

Forcing HTTPS login in WordPress

Have you recently made any changes to the wp-config.php file to force HTTPS on the login page of WordPress.

define(‘FORCE_SSL_LOGIN’, true);
define(‘FORCE_SSL_ADMIN’, true);
If you’ve added any of the above constant in the wp-config.php file, then remove it from there.

Disable all plugins

Some security plugins such as iThemes Security (previously known as Better WP Security) have an option to force SSL on your site for only admin page, and for all pages or posts. If you’ve checkmarked this option in the plugin’s page, and if your server doesn’t supports SSL, then you won’t be able to login to WordPress because of SSL error. What now?

That’s where you’ll need to deactivate all plugins, or you can also rename one plugin at a time to see if that has solved your problem. Renaming the plugin will instantly deactivate the plugin, and that’s why problems arising out of that plugin will be fixed.

To disable all plugins at once, use FTP client or your host’s File Manager and navigate to wp-content folder. Rename the “plugins” folder to “plugins.hold”. This will deactivate all plugins instantly. If you’re now able to login then it means that a plugin is the culprit, and in such a case you’ll need to find that plugin and remove it.

Edit your WP_Options table

From your cPanel, login to your phpMyAdmin, go to your WP_Options table where you will find your site URL and home URL starting with HTTPS. You just need to edit it back to HTTP (by removing the “S”).

So go ahead and follow these methods when you’re getting SSL error on login page of WordPress. Hopefully these tips should be able to help you solve your problem.

Note: To help you fix your everyday WordPress problems and errors, we’ve also started a new WordPress troubleshooting section.

Jika untung 5 jutaan di akhir tahun.. apakah harus bayar lagi pasal 17 ? "Berdasarkan ketentuan yang berlaku, penghasilan terbagi menjadi dua; penghasilan yang merupakan objek pajak dan penghasilan yang bukan objek pajak. Begitu pula cara pengenaan pajak penghasilan (PPh) atas penghasilan yang merupakan objek pajak, juga terbagi menjadi dua. Pertama, dikenakan PPh secara umum dengan menggunakan tarif pasal 17 (tarif umum), dan pengenaannya dilakukan di SPT Tahunan. Kedua, dikenakan PPh Final. Pengenaan PPh secara final berarti penghasilan yang diterima atau diperoleh akan dikenakan PPh dengan tarif tertentu, dan dasar pengenaan pajak tertentu pada saat penghasilan tersebut diterima atau diperoleh. PPh yang dikenakan, baik yang dipotong pihak lain maupun yang disetor sendiri, bukan merupakan pembayaran di muka atas PPh terutang, tetapi sudah langsung melunasi PPh terutang untuk penghasilan tersebut. Maka dari itu, penghasilan yang dikenakan PPh Final ini tidak akan dihitung lagi PPh nya di SPT Tahunan untuk dikenakan tarif umum bersama-sama dengan penghasilan lainnya. Begitu juga, PPh yang sudah dipotong atau dibayar tersebut juga bukan merupakan kredit pajak di SPT Tahunan. PPh Final menurut Peraturan Pemerintah Republik Indonesia Nomor 46 Tahun 2013 dikenakan pada wajib pajak pribadi dan badan yang memiliki omzet usaha kurang dari Rp 4,8 miliar dalam setahun."
