Tech Tool Shortcomings: Seeking Simple Solutions for Mac Users | October 09 2024, 16:13

So by the way, when I was cutting out this piece, I realized that even with my experience working on Macs and online, I can’t find two simple tools: 1) to download just a segment from YouTube. Not the whole multi-hour video, just from 9:30 to 9:45. Somehow no one can do this, they all offer to download the whole thing. 2) Screen recording with system sounds, not microphone sounds. Sounds from the microphone are recorded, but not the system sounds. I know that maybe you could use Zoom and turn on the recording there. But that seems like a rather convoluted way to do it.

In short, if anyone wants some fame (not sure about the money), write a utility for Macs that records a screen or screen segment with subsequent crop/trim, and a tool to download video segments from video hosting services like YT/VK as video files.

It turned out easier for me to download an hour-long video and trim it using QuickTime.

Exploring Milk as an Alternative to Water in Espresso Making | October 08 2024, 20:33

I wonder, what if instead of water we used milk to make espresso?

(From the image it seems unclear to many – there is no heating, no way for it to burn. Plus, there are different kinds of milk – like oat milk, for example)

Sosumi: The Playful Sound of Apple’s Legal Battles with The Beatles | October 06 2024, 17:59

1) It turns out the MacOS notification sound had a name, and it was Sosumi. It was used from 1991 to 2020, after which it was replaced with Sonumi. There’s a funny story behind the name.

2) These sounds have a creator. It’s Jim Reekes—Apple’s sound designer, and there’s a secret that wasn’t disclosed for about 10 years after his departure from the company.

3) The Beatles are partly the authors of the MacOS startup sound.

Now for the full story. There was a company called Apple Corps, organized by the Beatles. Its logo was also an apple (of course), hence there was a legal dispute with Apple, which ended, as the joke goes, with the agreement “I don’t give loans, and the bank doesn’t sell seeds.” Apple Inc. could use its name but was not allowed to venture into the music industry and use music-related names in its products.

Accordingly, any Apple ventures into music immediately alarmed lawyers from both sides. When it came to creating system sounds, the lawyers tensed up and asked Reekes to first, not use the name “Chime,” and second, please no melodies in the sounds. As a result, operating system sounds like Frog, Funk, Glass, and Hero appeared.

Eventually, Reekes worked hard on the startup sound and created a C major chord.

Reekes assures that while creating the C major chord, he was inspired by The Beatles’ song “A Day in the Life. I don’t know why I’m laughing here.

Returning to notifications. After much deliberation and attempts to find a neutral name, Reekes proposed the playful name “Let it Beep” in the style of The Beatles’ song “Let it Be”, but his colleagues thought it would be hard to accept. When someone suggested such a name would lead to legal disputes, Reekes jokingly replied: “So sue me,” and suddenly realized that this phrase would be perfect for the sound name. Eventually, they decided to rename the sound to “Sosumi. He told his bosses it was a Japanese word having nothing to do with music.

In macOS Big Sur, the original chime was replaced with another, which was named Sonumi. The original name was retained in the first public version of the OS, but later changed to “Sonumi. The sound file itself /System/Library/Sounds/ is still named Sosumi.aiff.

Now, the OS startup sound is completely removed. It seems you can enable it in the settings.

Dog Alarmed by Mysterious Paper Invasion | October 05 2024, 00:29

Sitting here, pressing the black-and-white keys on the first floor. Above, there is barking. Yuka, as a Shiba Inu, normally doesn’t bark at all. Well, like maybe once a year for various reasons. And now he’s giving a full serenade. I go to check, turning on the camera. It turned out that he had suddenly discovered a newly-purchased pack of printer paper opposite his couch, in a room where nothing new had appeared in his presence before. And there it was, such an aggressively white pack of paper with a whole 1000 sheets from Costco by the TV, clearly encroaching on his territory. He remained upset for quite a long time until I removed it. Later on, Yuka got to know it better. If it had been outside, he would definitely have peed on it, but inside, he just sniffed it for a long time, then cataloged it in his mind and no longer barks. That’s his exciting life.

Invasive Spotted Lanternflies and the Battle to Control Them | October 04 2024, 19:41

We currently have about a dozen Spotted Lanternflies on our porch — Spotted Lanternfly. Here’s a photo of one I’m holding. It’s an insect from the cicada family, about the size of a thumb phalanx. Generally harmless, although, of course, it depends on how you look at it, since at home, it periodically annoys the dog, and it also drains vineyards, not disdaining apples, peaches, cherries, maple, oak, and birch.

This creature is actually an immigrant from China. And it brought its whole ecosystem from China with it. So, listen up.

Until 2013, we didn’t have Lanternflies in the U.S. They arrived from China. But generally, animals always have some environmental dependencies, which is why they don’t just colonize the entire world, but stick to familiar habitats. The Lanternfly’s preferred tree is beautifully called the “Tree of Heaven” because of its ability to grow 20-30 meters tall. The botanical name of this tree is also telling — Ailanthus altissima. And this tree is native to China, where they used it to breed silkworms. Actually, it grows in many places, including Russia and Ukraine. And these Lanternflies really love this tree.

It was introduced to the U.S., where it has become a weed. And for the Lanternflies — it’s a feast. They lay their eggs on it, and each year there are more than the last. How to deal with this, it’s unclear, as the typical recommendation of “scrape the eggs off the trees, putting them in two bags with alcohol” obviously won’t be applied.

One option is to bring in the combat wasp, Anastatus orientalis, from China, which greedily devours Lanternfly eggs. Quite an amusing method. They lay their eggs inside the egg masses of the lanternfly. The larvae of the wasp develop inside the eggs of the lanternfly, consuming them from within, which prevents the hatching of the lanternflies.

However, scientists suspect that if the combat wasps proliferate and start eating more than just Lanternflies, we might have to bring in yet someone else from China who eats the wasps themselves.

Decoding Keystrokes: High Accuracy Typing Inference from Sound | October 03 2024, 14:22

11 years ago, I wondered if it was possible to tell by the sound of keystrokes whether someone was messaging in a messenger or not. In 2023, a scientific article is published with a prototype that can determine with 95% accuracy what a person is typing just by recording the keystrokes on a smartphone, and 93% accuracy when recorded through Zoom. The code in the article is declared to be available to other researchers. And they admit that they have not yet used language models, but with them, it should be really good. Link in the comments.

Exploring Mobile Communication Vulnerabilities: The SS7 Network Exposure | September 24 2024, 20:42

A very intriguing video about vulnerabilities in mobile communication.

In brief, the gist is this: due to the expansion of the network of cellular operators, control over who enters “the club” has been lost, and it’s fairly easy to gain unauthorized access to the SS7 network, through which mobile connections are managed. From there, one can do anything: intercept calls and SMS, record calls without the caller’s knowledge, and even track locations — in cities, it’s incredibly accurate. Access to the network simply costs money. And, of course, one must know what to do and how—it’s just knowledge, albeit rare.

A notable example is the case with Princess Latifa from Dubai, who was captured after an attack via SS7 allowed the location of her yacht captain’s phone to be pinpointed.

A live attack is demonstrated, in which a hacker intercepted a phone call intended for someone else. This was done by deceiving the network into thinking that the victim’s phone was in roaming, which allowed the hacker to redirect the call.

In the discussion, it is emphasized that, although newer protocols introduced with 5G are more secure, the transition to them is slow due to network effects: all operators need to switch at the same time to fully benefit from the advantages.

Conclusion: SMS is evil. Use authenticator apps or hardware tokens for two-factor authentication. Or, just don’t stick out so much that someone would not mind spending a few thousand dollars to hack specifically you.
