Register an email?

Years ago I created an account and put my reset email as by mistake, it should have been

Recently, I tried to access my old account but could not remember the password. When I tried to reset my email it wanted, so I went onto the website but found out that Yahoo now only has .com domains, not country specific ones.

Are there perhaps any tricks or solutions to this?

How to cascade register correctly?

Currently I have this 4 bit CPU as shown in the schematic diagram below. enter image description here

What I wish to achieve:

  • Add one more output register to make the CPU output a total of 8 bits
  • Show alphabet using the 8 bits output

My current trial:

  • Cout of the first IC connected to Cin of the second IC
  • Cascaded in a synchronous fashion enter image description here

What I unsure/don’t understand:

  • Should I connect the A~D pins of the second register to ALU?
  • The LOAD-bar pin is connected to LO-bar of the ALU. Should I add one more LO-bar to the ALU and connect it to the LOAD-bar of the second register?

Oracle 19c database instance doesn’t register with listener

I have just installed an oracle 19c ( to be exact) database on a centOS 8 virtual machine. The databases instances can all be started with sqlplus on the host machine. I have set up listener.ora and tnsnames.ora based on an existing (functioning) oracle 12c, which has a very similar setup.

I did the initial installation using the .rpm from Oracle, thinking that would make things easier. It probably didn’t make things any more difficult, but it meant that the directory structure was not what I’d have expected. Still, it isn’t as though it is unusable, just located differently. Having done that, I did a basic install of the DB instances I wanted (using pretty much all default settings) with dbca.

Finally, I setup listener.ora and tnsnames.ora based on the working 12c installation. The problem is, no matter what I do, the DB instances don’t seem to be registering themselves with the listener.

The tnsnames.ora looks like this:

## initially copied from linuxoracle12 (20200617-1112)  LISTENER_TEMP =   (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))   TMF =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME =     )   )  LISTENER_TMFDE =   (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))   LISTENER_TMF =   (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))   TEMP =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME =     )   )   TMFDE =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME =     )   ) 

The listener.ora looks like this:

## initially copied from linuxoracle12 (20200617-1117)  SID_LIST_LISTENER =  (SID_LIST =   (SID_DESC =    (GLOBAL_DBNAME = TMF)    (ORACLE_HOME = /opt/oracle/product/19c/dbhome_1)    (SID_NAME = TMF)   )   (SID_DESC =    (GLOBAL_DBNAME = TEMP)    (ORACLE_HOME = /opt/oracle/product/19c/dbhome_1)    (SID_NAME = TEMP)   )   (SID_DESC =    (GLOBAL_DBNAME = TMFDE)    (ORACLE_HOME = /opt/oracle/product/19c/dbhome_1)    (SID_NAME = TMFDE)   )  ) LISTENER =   (DESCRIPTION_LIST =     (DESCRIPTION =       (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))     )   ) 

As an example the initTEMP.ora looks like this:

## initially generated with dbca ## 20200617 added: *.local_listener='LISTENER_TEMP' TEMP.__data_transfer_cache_size=0 TEMP.__db_cache_size=855638016 TEMP.__inmemory_ext_roarea=0 TEMP.__inmemory_ext_rwarea=0 TEMP.__java_pool_size=0 TEMP.__large_pool_size=16777216 TEMP.__oracle_base='/opt/oracle'#ORACLE_BASE set from environment TEMP.__shared_io_pool_size=0 TEMP.__shared_pool_size=301989888 TEMP.__streams_pool_size=0 TEMP.__unified_pga_pool_size=0 *.audit_file_dest='/opt/oracle/admin/TEMP/adump' *.audit_trail='db' *.compatible='19.0.0' *.control_files='/opt/oracle/oradata/temp/TEMP/controlfile/o1_mf_hgkpt5t0_.ctl','/opt/oracle/fast_recovery_area/TEMP/controlfile/o1_mf_hgkpt5w0_.ctl' *.db_block_size=8192 *.db_create_file_dest='/opt/oracle/oradata/temp/' *.db_domain='' *.db_name='TEMP' *.db_recovery_file_dest='/opt/oracle/fast_recovery_area' *.db_recovery_file_dest_size=8256m *.diagnostic_dest='/opt/oracle' *.dispatchers='(PROTOCOL=TCP) (SERVICE=TEMPXDB)' *.local_listener='LISTENER_TEMP' *.open_cursors=300 *.pga_aggregate_target=378m *.processes=300 *.remote_login_passwordfile='EXCLUSIVE' *.sga_target=1134m *.undo_tablespace='UNDOTBS1' 

So far so good… I thought. But regardless of what I try, I cannot get the DB instances to register with the listener. When I run lsnrctl services, I get the following:

[oracle@linuxoracle19 admin]$   lsnrctl services  LSNRCTL for Linux: Version - Production on 17-JUN-2020 12:11:01  Copyright (c) 1991, 2019, Oracle.  All rights reserved.

In various posts and what not, I have read that status UNKNOWN, whilst not seriously bad, actually means that the service in question is not registered with the listener. This is exemplified when I try to connect using NetBeans or SQLDeveloper. In both cases I get the error:

Before anybody asks, yes, I did try tnsping. When I did, I got:

Can anybody out there tell me what is going wrong? I really have no idea why the current setup doesn’t work.

How to register meta field with checkbox to REST API with default value true?

I have a meta field with checkbox, it has by default checked value, but when I register it to REST API my checkbox become unchecked.

How can I get it checked by default?

Here is my code for metabox:

function modest_gutenberg_meta_add_meta_box() {     $  post_types = array('post', 'page', 'modest_portfolio');     foreach ($  post_types as $  post_type) {         add_meta_box(              'modest_gutenberg_meta_post_title_option',              esc_html__( 'Title Options', 'modest-gutenberg-meta' ),              'modest_gutenberg_meta_post_title_settings',              $  post_type,              'normal',              'high',              array('__back_compat_meta_box' => true));     } }  add_action( 'add_meta_boxes', 'modest_gutenberg_meta_add_meta_box' );  function modest_gutenberg_meta_post_title_settings($  post) {     $  visibility_title = get_post_meta($  post->ID, '_modest_gutenberg_meta_post_title_visibility', true);     $  checked_title = 'checked';     if($  visibility_title == 'unchecked' && !empty($  visibility_title)) {            $  checked_title = '';     }      wp_nonce_field( 'modest_gutenberg_meta_update_post_title_settings', 'modest_gutenberg_meta_update_post_title_nonce' );     ?>          <input type="checkbox" name="modest_gutenberg_meta_post_title_visibility_field" id="modest_gutenberg_meta_post_title_visibility_field" value="1" <?php echo $  checked_title; ?> />             <label for="modest_gutenberg_meta_post_title_visibility_field"><?php esc_html_e( 'Display Title', 'modest-gutenberg-meta' ); ?></label>      <?php }  function modest_gutenberg_meta_save_post_title_settings($  post_id, $  post) {      $  edit_cap = get_post_type_object( $  post->post_type )->cap->edit_post;     if( !current_user_can( $  edit_cap, $  post_id )) {         return;     }     if( !isset( $  _POST['modest_gutenberg_meta_update_post_title_nonce']) || !wp_verify_nonce( $  _POST['modest_gutenberg_meta_update_post_title_nonce'], 'modest_gutenberg_meta_update_post_title_settings' )) {         return;     }     if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {         return;     }      if(array_key_exists('modest_gutenberg_meta_post_title_visibility_field', $  _POST)) {         update_post_meta(              $  post_id,              '_modest_gutenberg_meta_post_title_visibility',              sanitize_text_field($  _POST['modest_gutenberg_meta_post_title_visibility_field'])         );     } else {         update_post_meta(              $  post_id,              '_modest_gutenberg_meta_post_title_visibility', 'unchecked');     } } 

And then I register_meta:

function modest_gutenberg_meta_register_meta() {     //title     register_meta( 'post', '_modest_gutenberg_meta_post_title_visibility', array(         'show_in_rest' => true,         'type' => 'boolean',         'single' => true,         'sanitize_callback' => 'sanitize_text_field',         'auth_callback' => function() {             return current_user_can( 'edit_posts' );         }     ) ); }  add_action('init', 'modest_gutenberg_meta_register_meta'); 

I’m registering meta for Gutenberg Plugin to add a new Sidebar, there I have ToggleControl, which make my meta update and it’s working.

But I can’t understand what am I doing wrong with default value?

How can I get my value checked by default inside WordPress REST API?

If I delete register_meta() function and switch inside add_meta_box() __back_compat_meta_box to false and refresh the page which I’m editing,

I will get my checkbox true and then if I register_meta() again and refresh page I will get my meta in REST API checked.

Sorry for my English, hope someone can help me)

Thanks in advance.

SharePoint Asset Register Template / Product

Currently using SharePoint 2007 Standard with a pending upgrade into SharePoint Online.

Can anyone advise of any off the shelf products that’ll deal with Asset Registration? I’m more than aware that this sort of thing can easily be done OOB with custom lists / forms but I’ve been asked to provide some alternative paid / commercial for comparison.

I’ll be checking SharePointReviews of course but if anyone has used such a product and had a good experience with it, it would be useful to know of it.

Thanks in advance Steven

How to create a register from DFF bit components?

I am a new student at computer architectures and my current task is to create a register of 4 bits.

We were a working DFF and my bit component seems to work.


My bit: By bit

I tried to create the register by splitting the data into 4 bits and use the Bit component on each of them: My Register

And it works while the load is 1, but when I change the load to 0 the output value – the value of q – is 15 (4 bits of 1).

Any ideas about why? thanks

Register application as a default one for a standard URI scheme

I’m adding support for handling telnet:// links to my application, what is the best way in regards to the user experience for doing so?

The application runs on Windows, macOS, and Linux, and doesn’t have “wizard” installers on any of them. On Windows, double-clicking the application uses the standard Squirrel installer (think Atom, Github Desktop, etc) – which just shows a gif while installing and then launches the application. As hassle-free as you can be, and it’s a similar experience on macOS and Linux.

This leaves a dilemma, what to do with the URI registration?

  • if it’s to only be done via preferences, then of course the question is do we enable it by default or no
  • if it’s not enabled by default, users for the large part have no reason to enable it, so most won’t have it on and thus the telnet:// handling will be pointless
  • if it is enabled by default, and that happens to override another application that’s already registered, then we’ll be a bad citizen
  • if we ask the user on the first launch what to do: well, the first launch is an overwhelming experience as it is, getting asked about telnet:// handling will just add to that

Happy to hear thoughts and feedback on this, thanks!
