Solution for Chrome USB debugging remote devices doesn't appear

Today I was forced to inspect crashing chrome browser. To inspect that i needed to use desktop chrome.

To do that there is pretty good tutorial: https://raygun.com/blog/debug-android-chrome/

But after completing all steps. Nothing appeared in "remote devices" on desktop.

After few hours i have found solution.

To fix that:

1. Download SDK Platform-Tools for Windows zip file. Extract..
2. Launch cmd.exe ( command prompt ). 
3. From extracted folder launch "C:\path_to_file\adb.exe devices" . You might get as i got - "List of devices attached: 9be86c14 unauthorized"
4. Now unplug your phone and plug it back. 
5. Check your phone that it allows PTP connection of USB debugging ( check raygun.com link ).
6. Repeat #3 step - launch "adb.exe devices" command again. You might get same message in cmd.exe window. BUT now check your phone. There should be confirmation popup window for mac address. Accept that.
7. Now just repeat same #3 step. As it shown from my screenshot i got success message "9a479b83 device".
8. Done. Now you should be able to detect the device under "remote devices" in google chrome. 

To inspect url on device:

1. On device open chrome and open desired url
2. On desktop open remote devices 
3. Click device
4. Near appeared list of "opened" tabs with shown urls find your "last one" and on right side click "inspect" button.
5. Done.

Happy debugging.

Let me know if it helped you. Or write where you stuck and how you solved it, so other people could save time. Thanks.

Redirect loop on admin login WordPress [Solved]

Once i faced the problem i googled and found some topics about the problem.

• https://wordpress.org/support/topic/redirect-loop-after-update-wordpress-441
• https://wordpress.org/support/topic/err_too_many_redirects-12 

Result of the discussion I found solutions which might help you in same cases.

If you still haven't figured out how to skip the loop - add "index.php" in address bar after "youdomain.com/wp-admin/" ( In result you will get "http://www.yourdomain.com/wp-admin/index.php" ) . It will allow you to access normally wordpress admin page without loop.

Solutions

Method 1

Check general settings ( settings -> general ). And make sure your addresses are same ( make them lowercase ).

Method 2

Go to Permalinks settings ( settings -> permalinks ) and change to plain.

Method 3 ( My situation )

None of first methods worked for me ( Method 1 was correct for me, and method 2 - i didn't wanted to change permalinks ). So i have checked code what is happening there... and noticed that index.php isn't loading on wp-admin/ ( which should.. ). So I have checked ".htaccess" file in dir ( and in root dir later ). And I found old code in .htaccess which ruined login process.

I have removed everything but wordpress comment surounded code, saved and wuallia... everything worked.


Let me know if it worked for you. Thanks for comment <3 p="">

Growing mushrooms at home (or outdoors)

I'm person which likes to harvest mushrooms in forest. But in my situation this season is not much rainy, and there is luck of mushrooms. So I found interesting article on how to grow mushrooms at home. Cool idea for me... no need to wait fall and even you can harvest mushrooms every week and also you can get money for selling these mushrooms for friends or piceries.... or farmers?

Growing mushrooms is pretty interesting thing and requires a lot to get "fruits". But with current people's ideas there are mushrooms kits which will help you to get first mushrooms pretty easy... You will not need any chemical clothes / scalpels and so on...

I suggest to read few how to articles:
Indoors growing
Outdoors growing

As I know now, a lot methods how to grow mushrooms. Starting from collecting mushroom spores from mushrooms which you can found in forest and finishing with the kits I mentioned. Coolest ones are growing mushrooms on logs. You will need some sticks / logs / drill / wax? Next you drill holes in fresh logs, put there spores; then stick there sticks and covering with wax, put in not windi and not sunny place. Done! Great huh?
After few hours of work you will be able to get mushroom fruits for a few years... like 3 or 4 if you do everything correctly. Spores requires like 6 months to grow there..

At the moment i look for spores supplier from which i could get them and grow them in my basement. Also thinking to try logs method...
