White hole
ASTROPHYSICAL BLACK HOLES AS A POTENTIAL SOURCE OF A SUBDOMINANT DARK-SECTOR COMPONENT Energy screening, historical population-integrated throughput, and a phenomenological source-term framework Preprint Abstract We examine whether energy released outside the horizons of accreting astrophysical black holes could produce a stable, subdominant dark-sector component. Production from the exterior plasma and extraction of rotational energy require explicit couplings. Energy that has crossed a classical event horizon cannot simply reappear outside because its products are invisible; any proposed horizon-mediated alternative needs a…
Linux - the best operating system
There are some things I didn't understand right away. For example, that an operating system shouldn't try to be your boss. It should be a tool. You buy a computer for yourself, not the other way around. You buy the hardware, install the system, and you should be able to do practically anything with that machine that you are technically capable of doing. And that's exactly why Linux is the best operating system for me. Not because it's the prettiest.…
Without Network
There was a time when the Internet seemed indestructible. Decentralized. Free. Independent of any single authority. Today, it's clear that reality is more complicated.
Neovim became my main one
Over the past twenty years, I have worked with almost everything: Vim, VSCode, JetBrains IDE, Sublime Text, Atom, Emacs.
CachyOS + Niri on ThinkPad
Over the past few years, I have tried a huge number of distributions, window managers, and desktop combinations.
Libertarianism
Libertarianism or why the stationary bandit is starting to die. There is one very uncomfortable thought. The state was never necessary. It was technically inevitable.
Home server system
My home system separates services into distinct roles with restricted network access. Some machines serve only the local network; others have controlled external connections or exchange events through specific endpoints. The...
Blockchain Predictive Analysis
The cryptocurrency market has no single authoritative order book across all venues. Traditional finance is also fragmented across exchanges and over-the-counter markets, so this is not unique to crypto. Centralized exchanges,...
Sphere Ark Project
This is a concept for an underground spherical shelter, not a verified construction specification. The proposed site is assumed to have groundwater at 10-12 metres and a potentially unstable clay slope; those assumptions...
Crypto Arbitrage in 2026
Crypto Arbitrage in 2026: What a Retail Quant Can Still Do There is a fairly common misconception that proper HFT, arbitrage, and strategies that are sensitive to latency and execution quality are now exclusively the domain of large funds. In traditional financial markets, that is largely true. But crypto works somewhat differently. There are still a huge number of independent exchanges, markets, instruments, and execution environments. Every venue has its own fees, APIs, liquidation rules, order book structure, pricing formulas,…
Arbitrage is life
I use “arbitrage” broadly here. Statistical trades, liquidation strategies and forecasts based on Mark Price can lose money even when implemented correctly. Mark Price is a reference value rather than an executable quote; knowing its formula does not guarantee an earlier or profitable trade. A price gap becomes an arbitrage opportunity only if the relevant legs can actually be executed and settled after fees, financing and transfer costs. Capital controls or sanctions can prevent that execution entirely. Small market size…
LLM about dimabagow
It is interesting to read how AI sees me; this is much more interactive than in the pre-AI era. Previously, you could simply look at the search results for your own name; now you can get an entire history, and that is despite the fact that I am far from being a public figure: Dossier: dimabagow / Dima Bagow 1. Who is this The public footprint quite unambiguously points to a person using the name Dima Bagow / Dmitry Bagow…
Eat Synthetic!
Many people envision synthetic food as a bland grey slop from sci-fi movies. In reality, everything could turn out exactly the opposite.
Large Language Models
Modern LLMs do not think in words. They work with vectors, probability distributions, and matrices of weights.
Quantum Superposition
Quantum superposition is one of those things that sound like esoteric nonsense after a third bottle of cognac. It is a basic feature of quantum physics, which underlies semiconductors, lasers and MRI. GPS also uses atomic...
Qubits and Blockchain
Every time news comes out about Google, IBM or some new superconducting qubit, experts start crawling out claiming: Bitcoin is dead.
Stargate
A series with a wonderful warm atmosphere, against which various scientific hypotheses are artistically played out.
Video Editing in Linux Console
This is an archive of MPlayer/MEncoder and FFmpeg recipes from the period described. Several package names, codecs, download hosts and build options are obsolete. The examples document the original workflow; check the...
Battlestar Galactica
Battlestar Galactica is one of the most unusual examples of science fiction, where space is a laboratory for studying human civilization.
St. Matthew Island
A very instructive story. In 1944, 29 reindeer were introduced to St. Matthew Island. With abundant forage and no resident reindeer predators, the population reached about 6,000 in 1963. This corresponds to an average compound...

The Big Crisis
This is Viktor Sergienko (Koshasty)'s historical account, with additions through 2011. Dates, prices, forecasts and first-person statements belong to that edition. The full text is retained; its household experiments are personal observations, not tested engineering or medical guidance. Land areas given as “sotkas” in Russian are translated as ares: 1 are = 100 m², so the 75-are plot is 0.75 hectares. Photo references belong to the source publication; this copy contains its text. There is such an author Koshasty, he…
Learn Everything Using the Terminal
This is a historical Linux command collection. nmon and the traffic monitors use terminal interfaces, not a desktop GUI. acpi -V shows available device information; acpi -v prints the version. PCI-register writes such as the...
Setting Up Wi-Fi in Debian
Historical instructions for Debian Lenny and the hardware of that period. Package names, repositories and WPA/TKIP settings are archival examples, not a current installation recipe. The DNS addresses 192.0.2.53 and 192.0.2.54...
Migrating a Website from the Terminal
Useful commands for transferring website files and databases via scp, rsync, and mysqldump.
Network in Debian
This historical example uses ifupdown and a static IPv4 address. It applies only when that interface is managed by ifupdown; do not disable other network managers indiscriminately. Bringing an interface down disconnects an SSH...
