My Ambitious 2026 Plan: From Galapagos Travel to Academic Achievements and Creative Pursuits | January 20 2026, 04:44

My plan for 2026:

– Travel to the Galápagos Islands, Ecuador for a week (summer)

– Finish and release a book on Information Retrieval (also summer, progressing slowly, first couple of chapters are already written. Already spent about 50-100 hours on this, the easy part)

– Release at least one scientific paper, probably on Data Mining (spring). Ideally, submit it somewhere to a journal (challenging). Already spent about 30 hours on this topic, a lot left to do.

– Make a step towards a PhD. Find professors, visit universities, understand the cost and assess my capabilities and resources.

– Continue studying fundamental mathematics and not die (linear algebra, calculus, probability theory, statistics, classical ML). In 2025, I spent about 200-400 hours on this topic.

– Continue studying Deep Learning and reach the “can teach” level. In 2025, I spent about 100-200 hours on this topic.

– Continue studying Data Mining/NLP.

– Update my book on RecSys, releasing version 2.0 with updates and corrections (autumn 2026)

– Make noticeable progress in painting and playing the piano. Specifically, learn Schubert’s serenade (Ständchen, D 889) completely and create at least one canvas that I wouldn’t be ashamed to give as a gift.

Spam Tactics: Money for Forms and the Illusion of Payouts | January 20 2026, 01:30

Spam in the mailbox. The letter says here’s some money, if you fill out a three-minute online form on the internet you’ll receive twice as much back through a digital gift card;) technology, darn it

US Visa Freeze for 75 Countries Amid Public Charge Concerns | January 14 2026, 15:23

If Fox News is to be believed, the US State Department is indefinitely suspending the processing of all types of visas for citizens of 75 countries, including Russia. Supposedly these measures will come into effect on January 21, 2026, and will remain in force until the department completes a full reassessment of verification procedures. It is stated that exceptions to this rule will be extremely rare and possible only after a thorough completion of all checks.

The reason is the aim to tighten the fight against “potential burdens on the American social security system”. Consular officers must deny visas to those who may become a “public charge”. Age, health status, English language proficiency, and financial situation are among the criteria.

P.S. Curious why there are so many chairs. Ten minutes ago, I sent Nadya a message on iMessage (!) “let’s buy a chair for mom on Ozone” after discussing chairs with mom on Signal. It seems like iMessage has not been known for leaking topics. Before this, I had no interest in chairs at all for many many years. Either advertising networks adapted quickly or it’s such a coincidence, I don’t know.

Unveiling Scientific Misnomers: A Cross-Cultural Exploration | January 14 2026, 04:46

Today I was surprised to learn that the Coriolis force is pronounced as CoriolIs force, not coriOlis force as we were taught in school. I started to investigate what else was wrong, and discovered something amazing.

It turns out what we called Gay-Lussac’s law is known as Charles’s Law in the rest of the world, and what we called Charles’s Law is known throughout the world as Gay-Lussac’s Law.

The Cartesian coordinate system here is Carthesian. Cartesius is just the Latinized name of René Descartes.

In our textbooks, the law of conservation of mass is called the Lomonosov-Lavoisier Law (what enters the chemical reaction = mass of the substances formed). In the rest of the world, it is exclusively the Law of Lavoisier (Lavoisier’s Law). Lomonosov got included here only because “whatever is taken from one body is added to another”.

Also, it turns out that if you have to explain Pythagoras’ theorem to someone in English, without a hint, it’s absolutely impossible to guess that it’s Pythagoras. Greek names are generally a mess. Thales here is pronounced as Teelis.

For some reason, in physics Roentgen is called RentgEnom, although it’s Röntgen with the emphasis on ö.

In Russia, a trapezoid is a quadrilateral with two sides parallel and two not. In the USA, our trapezoid is known as Trapezoid, and the word Trapezium here refers to a quadrilateral with no parallel sides at all. In the UK, it’s the opposite. Our trapezoid is Trapezium, and the “skewed” quadrilateral is Trapezoid.

Federal Reserve Under Pressure: Jerome Powell’s Video Address on Presidential Influence | January 12 2026, 21:43

In the Russian-speaking segment, this news is somehow not visible at all, none of the media outlets are writing about it. Yesterday, Jerome Powell, the chairman of the U.S. Federal Reserve, released a video message on the official Federal Reserve website’s homepage, stating that the president’s administration is putting pressure on him and his system, and part of this pressure involves trying to charge him for the building’s facade repairs.

The Federal Reserve System is the “bank of banks” and the main printing press of the world. Since the 1950s in the USA, there has been an unwritten rule: the president does not interfere with the Federal Reserve’s operations. If the Federal Reserve starts printing money or lowering rates just because the president needs to “boost” the economy before elections, the dollar will depreciate, and inflation will become uncontrollable.

Quote:

“I deeply respect the rule of law and accountability in our democracy. Of course, no one, including the Chairman of the Federal Reserve, is above the law, but this unprecedented action should be viewed in the broader context of threats from the administration and ongoing pressure.”

“The threat of criminal prosecution is a result of the Federal Reserve setting interest rates based on our best judgment of what serves the public interest, rather than according to the President’s preferences. The issue is whether the Federal Reserve can continue to set interest rates based on data and economic conditions — or whether monetary policy will be determined by political pressure or intimidation.”

If the pressure continues or if Powell is removed/arrested, there is a high chance that the loss of the Federal Reserve’s independence could lead to a sharp drop in the dollar’s value and an increase in the prices of gold and other assets.

As Nikolai Chapaev said in the textbook “Introduction to the Course ‘Philosophy and History of Education'”, “God forbid you live in an era of changes”…

Navigating the Future: Embracing Earth’s Magnetic Field as a GPS Alternative | January 10 2026, 17:41

I learned today that there is and is actively used a technology for navigation using the Earth’s magnetic field. It is used as a replacement or an extension of GPS.

For example, there is the Scandinavian ferry Express 5 of Bornholmslinjen, which insures against GPS problems (which do happen) by using MagNav navigation. Unlike GPS, the Earth’s magnetic field cannot be jammed or spoofed—it simply exists. The ferry follows the same route, and generally, navigation could even be achieved through household fishing sonars.

But there are a few startups that use this technology for indoor navigation, where GPS signals cannot reach. It’s claimed that the navigation accuracy is within 1 meter. That’s more interesting.

GiPStech, Oriient, Mapsted.

The basis of this technology is a process called magnetic fingerprinting. Engineers or mapping robots walk through a building with a smartphone, recording unique distortions of the magnetic field at every point. These distortions are created by the steel frame of the building, rebar in the walls, and large electrical equipment. A database is formed where each coordinate (x, y, z) corresponds to its unique magnetic field vector (intensity, inclination, deviation).

The collected data is uploaded to the cloud platform of the provider company. There, they undergo noise cleaning and are “stitched” together with the digital floor plan. When a user walks through a shopping center, their smartphone reads data from the built-in magnetometer in real-time. Special software (SDK) compares the current readings with those stored in the database. For accuracy to be within 1–2 meters, the system relies not only on magnets. It uses sensor fusion—combining data from the magnetic field with inertial sensors (accelerometer counts steps, gyroscope determines turns) and sometimes Wi-Fi/Bluetooth signals for rough localization.

This technology is certainly being actively implemented for drones. The main technical difficulty there is dealing with their own interference and considering that the magnetic field changes, requiring constant map updates. Electrics, engines create strong magnetic fields, which “drown out” the natural background of the Earth. However, various filtering algorithms (including neural networks) are used, which in real-time “subtract” motor interference from the overall sensor readings. From what I understand, at high altitudes (kilometers), the magnetic field is more “smooth”, therefore the accuracy is lower (about 1–5 km). But if several drones fly together and exchange signals, overall they can provide very good accuracy each. Additionally, a group of drones can measure the gradient (rate of change) of the magnetic field in space, tying location not to absolute values, but to relative ones. Essentially, using a group of drones turns the navigation system from a set of individual receivers into a distributed phased array antenna, capable of filtering global interferences and working with much weaker useful signals. Considering that small drones capable of staying airborne for long periods can be released into the air by the hundreds (and cost pennies), this is a quite promising area for military.

There’s an interesting startup, Zerokey. They release QUANTUM RTLS 2.0. This device provides spatial accuracy to 1.5mm. It’s used in production, for example. Their video shows a “watch” on a worker’s hand that monitors the correctness of assembling something on a table. Here, the principle is ultrasonic, and it’s understandable that these “watches” are paired with stationary sensors and further multilateration.

Cinema Meets Culture: The Indian Diaspora and Their Movie Rituals | January 09 2026, 06:09

I noticed that there is a huge gathering of Indians in our cinema, and it turns out it’s because the cinemas and the local Indian diaspora have found common ground. Today there were 13 showings of The Raja Saab in three languages – Tamil (in which the film was originally made), Telugu, and Hindi. The genre is fantasy horror comedy. There were also two showings today of Parasakthi in Tamil and two of Sarvam Maya in Malayalam.

And it was men only. I googled why. Superstars like Prabhas (The Raja Saab) have huge organized fan clubs. In Indian culture, “premiere night” and the first morning sessions are the territory of hardcore fans – and they are predominantly young men. They come to make noise, whistle, dance in front of the screen, and shout various things during the show. Many Indian families and women prefer to avoid this “crazy” atmosphere of the first sessions, opting for calmer showings on Saturday or Sunday.
