Chaos in the Village: Escaped Huskies Trigger Community Alarm | November 09 2025, 22:55

Something crazy is happening in our village. First, the owner of two huskies posts on nextdoor that they ran away from home and asks people to notify him if anyone sees them, warning that they are skittish. Then, about two hours later, the chihuahua owner posts that the escaped huskies killed his dog and also a neighbor’s chicken. The husky owner deleted his first post. Everyone in the village is grabbing their popcorn. It’s sad about the dogs. I’m always afraid that Yuki will run away like that, he’s also a fighter and fiercely hates all dogs in the world except himself.

The Evolution of the Albanian Virus: From Joke to Cyberthreat | November 07 2025, 14:21

“Hello. I am an Albanian virus, but due to the low level of technology in my country, I cannot do anything to your computer. Please kindly delete one file on your computer and then forward me to other users.”

Here’s the 2025 version. The line they ask to insert into the terminal – echo “” | base64 -d | bash

This line contains curl, pointing to 217.119.139.117 whose result is passed to `nohup bash`. And from this address, a script is loaded, of course obfuscated.

Naturally, no available LLM agrees to decrypt it. But Qwen didn’t mind.

Upon execution, the script gathers information from Chrome, Brave, Edge, Firefox, and others, extracting cookie files, autocomplete history, and system login data, collects crypto wallets like Electrum, Coinomi, Exodus, Atomic, Wasabi, Ledger Live, and others, gathers content from the “Notes” macOS app with attached media files, data from the Keychain (passwords), and also scans the desktop and documents for files of certain extensions. The collected data are archived and sent to a remote server with the IP address 217.119.139.117.

To ensure persistent access, the script creates hidden launch services (LaunchDaemons) with random names, making it difficult to detect. It can download and replace the legitimate Ledger Live application with a modified version.

Such is the Albanian virus)

Exploring SingleFile: The Chrome Extension for Easy Web Page Sharing | November 05 2025, 17:45

I found a useful Chrome extension – SingleFile. It solves a problem like this – you need to share a browser page that is not public, for example, via iMessage or Telegram. This is not so trivial to do. For example, you can save a .mhtml file from the browser on your laptop, and send it, but only recipients on an iPhone cannot open it. Saving as a standard .html is also not an option, as images and styles are not preserved. Taking a screenshot only captures a small fragment. Installing an extension that creates a long, large PNG of the entire page – this PNG cannot be opened on an iPhone from Telegram at least, only the top renders. Printing to PDF is also not a solution – the result is very poor and highly dependent on the developers’ desire to make a print-friendly version.

SingleFile allows you to create a snapshot of a page from the browser, a regular .html, which can be opened anywhere, with embedded styles and images. But what is especially convenient, before exporting, you can remove anything you don’t want to share through the WebInspector, and it won’t appear in the final .html. The extension is open source on GitHub, and it doesn’t send anything anywhere. Apparently, if there was dynamic loading through JS on the page, it saves not the JS, but the result of the loading, and the JS is cut out.

In general, it’s convenient, a good thing, use it.

Smart Car Seat Selection: How My Tesla Knows the Driver | November 03 2025, 14:29

Incidentally, in my Tesla, there’s a very clever system for identifying the driver. If I enter the car first but sit in the passenger seat, placing my phone immediately in the central console for charging, and then Nadia enters second but sits in the driver’s seat and also places her phone there, her profile is selected automatically because she’s the driver, even though both phones are on charge under the central console.

So, there are two possibilities: either there is an antenna which can precisely detect that a phone has crossed the driver’s door rather than entering the car in any other way, or there is a camera focused on the driver. In any case, it’s very reassuring that it “just works”.

Name Games in Politics: The Curious Case of Ommair Butt’s Campaign Sign | October 30 2025, 12:26

I wonder why this Republican running for Congress from our little district didn’t at least use a pseudonym? Or does the context switch on for normal people and they just don’t see that the word butt means buttocks?

Samuel Morse: From Painter to Telegraph Pioneer | October 28 2025, 15:00

At the “Rzhipopisi” exhibition, a painting titled “Paris through the Eyes of Samuel Morse” was showcased. Essentially, dots and dashes—it sparked the idea for this post. Few know that Samuel Morse was actually an artist, and quite a decent one—check out a couple of his paintings attached to this post. But he was only “decent” by our standards—surrounded by many equally skilled artists, he considered himself a failure in this realm and devoted the second half of his life, 35 years, solely to the telegraph. (By the way, Hitler was also an artist, amateurishly decent, but more mediocre compared to Morse amidst his contemporaries, yet he ventured into politics). In the attached photos, there’s a painting with paintings. Its actual size is about two meters and among the paintings hanging there is even the Mona Lisa (La Joconde) by Leonardo da Vinci, which wasn’t valued back then as it is now. It mainly became famous after it was stolen from the Louvre, and then fervently searched for and found by the entire world.

By the way, Morse Code was not invented by Morse, but by Alfred Vail, his colleague—a fact Morse later repeatedly denied (while also attributing the invention of the telegraph itself to himself). In 1848, the Vail/Morse code was refined by the German Friedrich Gerke. The code, improved by Gerke, was used until new technologies came along.

(By the way, I don’t understand why it’s Morse and not Morz. He was American, and nobody ever called him Morse.)

Indeed, among people who were artists, about whom everyone has forgotten that they were artists because they remembered something else, it is worth mentioning besides Hitler, also Winston Churchill and George W. Bush Jr.

Unveiling “Recommender Algorithms”: A Comprehensive Guide on Recommendation Systems | October 25 2025, 17:36

I finally released a book on #RecSys! It’s called Recommender Algorithms, where I’ve compiled over 50 recommendation algorithms with detailed mathematical derivations, thorough explanations, and code examples.

https://www.testmysearch.com/books/recommender-algorithms.html

It all started early this spring in Germany, when I attended an ACM conference and sketched out the first structure of the book while analyzing the talks from the RecSys track. And now, just six months later, it has come to life.

Why did I write it? Because neither online nor in print is there a single, accessible resource that deeply explores recommendation algorithms of various types and purposes. There are articles focused on small subsets, but collecting and systematizing approaches—from foundational methods to the very latest—seems to have never been done before. I don’t know if I succeeded, but I’d love to hear your feedback.

Please like & share!
