Low sound quality in Ubuntu 18.04.2 and white noise in main microphones + problems with crackling (echo suppression has not been resolved)

As the title says, I face problems with very poor audio quality and big microphone cracking + white noise in Ubuntu 18.04.2. This is a relatively new installation of Ubuntu. The only changes I make to the system are the installation of some programs like Discord, Steam, Spotify and Wine. I tried the fix from installing OSS and activating the microphone's echo cancellation, both of which do nothing. My motherboard is a gigabyte of H81M-DS2 (Rev.3.0) (Realtek Onboard Audio), if that helps. All help is appreciated! Apart from these problems, I love Ubuntu so far!

WordPress – I try to post by echo into a PHP file

I am working on a child motif that uses an ultimate member and redefines some of its features. Previously, he redefined the follow-up button and sent the information to a payment form. The form then sent the information to a Javascript file. The form is no longer used, so we're trying to send the information directly to a Javascript file, and I have not been using PHP for some time, so I'm a little lost. The only options that I find are form actions and methods that do not work. The function is

                                if (in_array ("um_customer", $ res-> roles)) {
$ nav_link = UM () -> permalinks () -> get_current_url (get_option (& permalink_structure & # 39;));
$ nav_link = remove_query_arg (& # 39; at_action & # 39 ;, $ nav_link);
$ nav_link = remove_query_arg (& # 39; subnav & # 39 ;, $ nav_link);
$ nav_link = add_query_arg (& # 39; profile tab & # 39 ;, $ id, $ nav_link);

And before that was the trigger

echo & # 39; follow & # 39;

The echo echo prints a "Follow" button, but the button appears, but I try to move the values ​​like "user1" and "user2" to another PHP file that inserts them into the database and the button you want to change This was sent in the other PHP file by the previous team. I'm having trouble sending it there. The previous method was a javascript file from the last line. This line generated the button that pressed a PHP code displayed form that took the payment information and then sent to a js form that took the information and verified the payment format, changed the "follow" to "follow request sent" and the remainder was sent to a PHP form, which, as I said, enter the information in the mysql database and give the second user the option to accept the following request. Ultimate Member does not offer this option, which is why it has been changed to a subordinate topic like this. Just the button to send the information to the php form. A And I have this problem with this button. Every help is appreciated.

Echo text if the user is logged in, but NOT the author of the post

Try your template tags (or wherever in your design):

$ post = get_post ();

// Something went wrong, bail. (You should always have a job, theoretically)
if (! $ post) {
return it incorrectly;

$ current_user = get_current_user_id ();

// Suppose only registered users can subscribe.
if (! $ current_user) {
return it incorrectly;

Return Absinthe ($ post-> post_author)! == Absint ($ current_user);

unix – basic echo implementation in Rust

I am looking for a possible help in implementing the Unix command echo in Rust. That's what I've got so far, but it's just basic functionality. I also need to implement the -n flag and -e flag, which can handle the line breaks, tabs, and backslashes. For everyone else, it should panic.

Use std :: env;

fn main () {
// starts command-line arguments by the name of the program
Let mut input = env :: args (). skip (1);

// Search for the next value in the command-line argument
if we have a few (arg) = input.next () {
print! ("{}", arg);

// traverses remaining arguments and prints a leading space
for arg in input {
print! ("{}", arg);
println! ();

Windows – Disabling the Unicode BOM from the PowerShell Echo Output?

I would like to create some short configuration files echo by PowerShell, but unfortunately by default a leading Unicode BOM is created at the top of the files. This destroys applications like pip that have not yet learned to ignore the bill of materials. Is there a flag or environment variable or one from which the bill of material can be sent out?
