Squid unexpectedly stopped working

Posted by | Network and Internet, Ubuntu |

Squid unexpectedly stopped working with my home internet connection. I created a temporary user:

sudo service squid reload

tried the following command

curl -v -x https://developernote.com:3129 --proxy-user temp:<password> -I https://api.ipify.org/

Using GDPR with 3-rd party Advertising SDKs

Posted by | Network and Internet | Tagged |

It is clear enough from Google docs how to show consent form in an Android app with Google Mobile Ads SDK:

Checking the speed of my home internet.

Posted by | Network and Internet |

I have 50 Mbit internet at home. If I test its speed with speedtest.net I get download speed 56 Mbit/s and upload speed 5.56 Mbit/s that is really good:

and if I download a file with torrent the speed is 6+ MB/s, but if I download a file with HTTP or SFTP the speed can be less than 500 KB/s that is 10 times slower. For example, if I download Ubuntu 18.10 on my VPS the speed is 24 MB/s:
