opened the Home Assistant page on my phone, and the living room temperature jumped from 26.4°C to 26.5°C, and I didn't touch the screen. Why should the webpage move on its own? I set up the smallest WebSocket service on my computer, using the most basic socket to handle and break down the frame and walk through it. I finally understood this line that refused to hang up. ...

Switching from WiFi to data on your phone, and the webpage suddenly stops being online? I flipped through the response heads and found that my own little blog had already announced the Alt-SVC H3. This article explains how QUIC created a new TCP on UDP, why the queue blocking disappeared, and when the home network will finally benefit....

Changing DNS or still showing ads? I caught a bag and saw clearly: traditional DNS using UDP 53 is basically a postcard, with the website address blatantly written on it, and anyone can view or change it halfway. Encrypted DNS means putting postcards in an envelope: browser secure DNS, Android private DNS, and router side switches, each with its own layer. This article explains the path and costs in one go....

If the download drops to 97%, do you have to start over? Breakpoint resume is completed by HTTP Range requests and 206 responses. I took a file from my own and split it into 4 segments in parallel, then reassembled the MD5 file exactly like the original. The secret to the multithreaded downloader's acceleration lies in this duo....

The numeric codes 404, 502, and 301 are the first sentences of each server reply. I tried out a service that lets you randomly click status codes one by one. Numbers 4 are mostly your fault, 5 is the site admin's fault. If you can't open after reading, don't refresh blindly....

My cousin saw that I had pasted a string of characters starting with 'magnet' into qBittorrent, so he downloaded it and started running on its own. He asked me which cloud drive this URL was from. In fact, it's not a website at all—it's the fingerprint of a document. I used Python to split the link, calculating the tracker, DHT, and block verification accounts all at once....

typing \fnnas\ on the computer doesn't connect to NAS, so switching to 192.168.31.20 seconds to enter is not a faulty NAS, but mDNS failing to translate the name into a house number. I checked the UDP 5353 port thoroughly and figured out why casting can show up TVs and why names sometimes work and sometimes don't. ...

After the router restarts, it takes a minute or two to get the internet—not because it's slow, but because it does six tasks in order. I use a stopwatch to go from plug-in count to the phone being able to browse the web: kernel self-check, reading configurations, WiFi activating first, WAN dialing, DHCP dispatch, service returning. Once you understand this order, you can immediately see where to find the root cause of problems after restarting without internet....

Watching videos and dragging progress bars responds instantly, but downloading takes half a day. I dug into an M3U8 checklist and counted: a 10-minute video was split into 64 small clips, each 10 seconds at 1.9MB. The progress bar, quality switching, and live streaming delay were all thanks to this cutting method....

The utm_source and utm_medium after the website address question mark are the operational statistics sources, showing which channel you clicked in; But the WeChat article parameter is the article's ID card, and deleting it directly results in an error and won't open the page. I tested the consequences of deleting parameter in two types of links, and here's a comparison table showing which can be deleted and which absolutely cannot be moved....
