I haven’t been very active here lately. However, I’ve been quite active on my Telegram channel. I’ve been posting once a day since the beginning of November. The content is mostly shitposting, or “food for thought” kind of stuff. Most posts are in Russian, but if you have a Telegram account, automatic translation is available. I believe it uses Google Translate, and surprisingly, the translations are good. Take a look if you’re interested.

I’ve been trying to connect my Sony ZV-E10 to my phone over USB so I could use the phone as an external monitor. Everyone on YouTube suggests using the Monitor+ app, so I decided to follow that advice. However, every time I tried, I got the following error message: Unable to connect to your device, either PC Remote is not turned on or the device is not supported. After I finally solved the problem, I discovered that the solution was actually in the app’s help menu (the ? button on the main screen). I had looked at it while troubleshooting, but I wasn’t convinced the solution applied to my situation. It turns out it did. ...

One essential part of my workflow is remapping the Caps Lock key to act as Ctrl when held and Esc when tapped. It’s always one of the very first things I set up whenever I get a new computer. I’m so used to it that whenever I help someone with tech issues and have to use their computer, I start stumbling over basic tasks—and I can almost tell they begin to doubt if I’m actually good with computers. ...

Just today I installed Tailscale on a VPS and was wondering why it could discover all machines on my tailnet. Even though I specifically didn’t give it any grants or ACL rules. Turns out, new machines have permissions of the authorizing user when first authorized. These devices were added by me so they assume my identity. — Alex from Tailscale In other words, tailscale on a machine without tags can do everything user can do. Limited only by the capabilities of the Tailscale client software. Luckily, it doesn’t include being able to edit the ACL. ...

I was surprised today to find out that Firefox was using my ISP’s DNS server — even though I had a local Pi-hole set up to use Cloudflare’s 1.1.1.1. It was my mistake. When I set up Pi-hole in my router’s DHCP settings, I forgot about DHCPv6. Once I added the local IPv6 address of my Pi-hole as the DNS server for DHCPv6, my ISP’s DNS server stopped showing up in the test. ...

Let’s say you have a Samsung phone. You connect to a Wi-Fi network and get a notification saying: [Wi-Fi name] has no internet access This could happen because your phone isn’t getting DNS responses for certain domains, such as: www.google.com google.com connectivitycheck.gstatic.com play.googleapis.com www.goooooooooooooooooooooooooooooooooooooooooooooooooooooooooogle.com (not a joke) …and a few others. You can find the full list by capturing the DNS queries your phone makes when connecting to Wi-Fi. I ran into this issue when trying to connect to my home Wi-Fi, and my Pi-hole was actively blocking DNS requests. ...
