Keyboard issue in Minecraft on Android

My son plays Minecraft on their Android tablet (Huawei MatePad 10.4 2022). And recently he faced with problem of using Huawei Smart Keyboard. The keyboard works well until you press the Enter key (entering to the chat). After exiting the chat you can't do anything (on keyboard) cause Android think that you are still typing in the chat and suggests you proper words (over the game).

Keenetic Mesh Wi-Fi | Periodic packets loss

To improve quality of WiFi coverage in my apartment I bought a second Keenetic Giga router (KN-1011) in addition to Keenetic Giga (KN-1010). From my perspective Keenetic is the best router for home usage. This confirms the presence of Mesh feature that can be configured by simple wizard.


The second router was placed in second room behind 2 walls from the primary router and connected by Ethernet cable Cat 5e (1 Gbps). 

Everything was perfect until I decided to play online game where I felt periodic freezes. ping shows loss of 2 packets per ~ 1 munite.

Exchange 2016 - Issues with ECP/OWA after installing updates/KB

For several reasons after installation updates/KB (for example KB4536987) you may faced with some backfires. I collected 3 type of issues and their fixes.

Issue #1 - Lack os styles on ECP page


After authentication on ECP page you may see only text and hyperlinks without any images and styles.

How to fix

Run the script "C:\Program Files\Microsoft\Exchange Server\V15\Bin\UpdateCas.ps1" or do following manual steps:
  • Go to "C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ecp" folder and find the folder with latest version number of your server (e.g. "15.1.1913.7") and it will be empty.
  • Open folder with previous version number (e.g. "15.1.1913.5") and copy all data to the new folder (e.g. "15.1.1913.7").
  • Restart IIS. Reload the ECP page.

Exchange 2016: Issue of breaking email address in angle brackets

Recently noticed the unusual behavior (an issue) of Microsoft Exchange 2016 when displaying email addresses.
If in the body of an email (Content/Header section) specify an email address (From, To or Cc headers) twice, where the second time is in angle brackets, the address will be broken. The part of the address after the first character @ moves to the address in brackets, thereby preventing the possibility of an answer to this email.

I assume that the function that should extract the correct email addresses from the headers does not work correctly.

Several tests

Original email address (that used while sending)The final email address (OWA, Outlook)
administrator@test.local <administrator@test.local>"administrator@" <test.local administrator@test.local>
administrator@_ <administrator@test.local>administrator@ <_ administrator@test.local>
administrator@domain<administrator@test.local>administrator@ <domainadministrator@test.local>
administrator@><administrator@test.local><administrator@>
<administrator@><administrator@test.local><administrator@>
<@administrator@><administrator@test.local><@administrator@><administrator@test.local>
administrator@<administrator@test.local><administrator@>
<script>@><administrator@test.local><script>
administrator@test.local@ <administrator@test.local>"administrator@" <test.local@administrator@test.local>
