Fear and Control

History is something not many people study or try to learn from—whether from our past mistakes or successes. We often think that what is happening now around the world is unprecedented, that we are on the brink of the end. But it has always been like this, ever since humans began thinking beyond their basic needs: food, shelter, sleep, and reproduction.

We constantly fear that our little space in the world will be disrupted, our comfort taken away, and our way of life destroyed. That’s when the clever man steps in—the one who looks for cracks in our emotions to control and exploit us. Kings are master manipulators, ruling over those who need direction or who, driven by self-interest, seek to achieve common goals—usually benefiting greatly by bending the knee.

Our primal emotion, fear, is the ruler of our thoughts. It corrupts our feelings, generates dark ideas, and can even paralyze us. A person without fear is often labeled a psychopath—someone who walks among us without empathy or remorse. The perfect king is a noble psychopath: charming and manipulative, seducing others into war in the name of something—something we all desire: money, property, or heavenly redemption.

Sitting around a table with their minds in overdrive, these rulers realized that keeping people afraid is the most effective way to govern.

Over time, we all learned from our kings. Those without remorse—greedy, vain, envious, and ruthless—have developed efficient and effective ways to manipulate others for their own gain, with fear as their secret weapon.

Our last global crisis, in 2019, proved that when we are all afraid at once, we become easy to manipulate. We willingly gave up our liberties without a second thought. We became a scared herd, led not by leaders, but by fear itself.

It is a fact that before this crisis, the world was in a state of protest against the status quo. In Asia, people were demanding more freedom; in America, civil rights movements surged; in Europe, citizens were calling for transparency and an end to state corruption. The younger generation was fearless, and for a moment, it seemed like something in the global power structure might crack.

Then came the perfect excuse to stop the avalanche of change—a disease, something invisible that could kill us all. We were told to socially distance, stay indoors, avoid questioning authority, and accept a new system of control. For three years, the world was gripped by constant stress: daily death counts, cries of “fake news,” and growing political division.

As time passed, we realized it was indeed a lethal disease—but also a conveniently timed one. It cooled the streets and allowed the ruling powers to reset the machinery that had, for a moment, stopped shielding them from the people.

It was a highly convenient problem—something that killed millions and terrified millions more.

Social media played a crucial role in helping the kings control the narrative. It became a filter of what could be said publicly. A tight algorithm would ban you if you challenged the measures they claimed were keeping us “safe.”

This might sound like a hate song against ruling parties, but it’s undeniable: they have used fear to control us—our markets, our education systems, our social media, our wars—and most dangerously, to become the sole owners of truth.

Control is necessary in society—but not when it’s used against us. Do you remember the parties held in London during the lockdowns? The rulers of England were drinking and hugging while, on TV, they were telling everyone else to keep their distance.

In the end, we must understand that fear controls everything we do. Turn off the alarms. Read between the lines. Keep an open mind. And remember: we are all mortal—but the world will keep turning around the Sun until we find another place to call home.

Don’t fear—think.

Don’t fear—learn.

Don’t fear—remember.

Don’t fear—open your eyes.

Are We Living in a Simulation?

Exploring the Science, Math, and Spiritual Echoes of the Simulation Hypothesis

Are We Living in a Simulation?

Exploring the Science, Math, and Spiritual Echoes of the Simulation Hypothesis

What if everything you know — your thoughts, your memories, your sense of time and space — is just code? It might sound like science fiction, but there is a serious philosophical and mathematical theory behind the idea that we could be living inside a computer simulation.

This is known as the Simulation Hypothesis.

Where Did This Idea Come From?

In 2003, philosopher Nick Bostrom proposed a thought-provoking argument:

One of the following must be true:

Civilizations go extinct before developing the ability to simulate reality. They develop the technology but lose interest in using it. We are almost certainly living in a simulation.

If the first two are unlikely, then the third becomes statistically more probable.

The Mathematical and Scientific Foundations

1. Bayesian Probability

Bostrom’s logic relies on probability: if simulated beings vastly outnumber real ones, then statistically, we’re more likely to be among the simulated.

2. The Universe as Code

Several areas of science support this possibility:

Cellular automata: Simple mathematical rules generate complex patterns, like in simulations. Quantum physics: The observer effect makes reality seem like it “renders” only when observed — like a video game. Error-correcting codes: Found in string theory equations — the same kind used in computer programs.

3. The Brain as a Machine

If consciousness results from information processing, then it could, in theory, be replicated or simulated in a powerful enough system.

What Does Religion Say?

Many ancient religions suggest that this life is not the true reality — a concept surprisingly similar to the Simulation Hypothesis.

Hinduism – maya (illusion): “The unreal has no being; the real never ceases to be.” — Bhagavad Gita 2:16 Buddhism – samsara (illusory cycles): “All conditioned things are like a dream, a phantom, a bubble.” — The Diamond Sutra Christianity – temporary physical realm: “For what is seen is temporary, but what is unseen is eternal.” — 2 Corinthians 4:18 Islam – life as a test: “This worldly life is nothing but play and amusement…” — Qur’an 6:32

In this way, the Simulation Hypothesis can be seen as a technological reinterpretation of age-old spiritual insights — where “God” may be reimagined as the “Programmer.”

Why It Matters

Even without proof, the idea challenges how we understand:

Consciousness Ethics The nature of reality The possible existence of a higher order

Whether interpreted scientifically or spiritually, the question remains: What is real?

Final Thoughts

We may never know for sure if we’re in a simulation, but the implications are worth thinking about. Real or not, our experiences, relationships, and choices still matter.

Perhaps the real question isn’t “Are we in a simulation?”

But rather: “How should we live, even if we are?”

HIFI Audio (Are audiophiles crazy?)

What Is HiFi Audio?

“HiFi” stands for High Fidelity, and it’s all about reproducing music as accurately as possible—no distortion, no coloration, just pure sound. For audiophiles, it’s not just about hearing the music, it’s about feeling it, capturing every nuance the artist intended.

The Audiophile Mindset

Audiophiles are often meticulous. They compare headphone impedance curves, obsess over lossless file formats, and can spend weeks “burning in” a new pair of speakers just to hear how they settle. To outsiders, it may look like madness—but to audiophiles, it’s a pursuit of perfection.

Are they crazy? Not necessarily. They’re just passionate—and like any hobby (wine tasting, watch collecting, photography), it comes with its own deep rabbit holes.

Can You Really Hear the Difference?

This is where things get controversial.

Some gear upgrades make a clear difference—like moving from laptop speakers to a decent pair of headphones. But other elements, like $500 power cables or gold-plated RCA connectors, might fall into the realm of placebo. Blind tests often show that beyond a certain price point, diminishing returns kick in hard.

Still, audiophiles argue that it’s not always about measurable differences—sometimes, it’s about the experience.

The Joy of Listening

What makes an audiophile unique isn’t how much money they spend—it’s how deeply they listen.

An audiophile might close their eyes during a track, pick out the gentle hum of a bass line or the slight air around a cymbal hit, and feel immersed in a way most casual listeners never do. For them, music isn’t background noise—it’s an event.

So, Are They Crazy?

Maybe a little. But aren’t we all, when it comes to the things we love?

In a world where everything is compressed, rushed, and mass-produced, there’s something deeply human about someone who just wants to slow down, sit in silence, and really listen.

So no—they’re not crazy. They’re just tuned in to a different frequency.

EMI (Electro Magnetic Interference) on guitars.

There is something that concerns everyone who starts playing electric guitar regulary at home or not in a professional environment. I am talking about those undesired nosies you can hear while not struming or picking your guitar. Some people call it humming, hissing, buzzing and if you google it you might find terms as 60 hz loop noise, and so on. we all know the noise, and having read and investigated this problem I found that the main cause for this noise is the EMI or electro magnetic interference. how do you know the sound is not coming from your amp? just turn all the way down your guitar volume know and if there is no noise you are being affected by EMI. the sources are usually the wifi routers, light dimmers, computer screens, fans, mobile phones, wireless devices, and any source  emitting radio or magnetic signals. as we usually play in bedrooms or small home studios we are usually surrounded by one or more of the aforementioned devices. the ones making more problems are computers (desktops) with huge screens and/or cooling fans of low quality or set for high performance (gaming or heavy use)

We usually have electric guitars with single coil pick ups, we can go over explaining the specs of these pick ups, for that matter you can do your own research, but if you are just starting you might find yourself ovewhelmed by this problem and might think that your cables are faulty and even worse that your guitar is just broken or bad.

solutions:

1. Turn off all wireless devices nearby your area of practice.

2. Use laptops, they are less likely to cause problems.

3. Move around with your guitar, try to find a spot in the room that has less EMI

4. Don’t leave mobile phones or ipads chargers plugged while not being used.

5. Avoid light dimmers, use simple light switches.

6. Large fluorecent lights are a big source of EMI.

7. Don’t play too close to a TV set, radio or computer.

8. Don’t play too close to a fan or air conditioning system.

9. If you are using a modeling amp, it might be a source of EMI.  Play not to close to it.

10. In short try to avoid any electrical device that uses magnetism or electricity nearby yor practice, o music studio.

There is another kind of noises you can get while playing guitar, and I will try to talk about it in ther posts.

as a reference please watch this video I found on youtube:

Finding a guitar in Shenzhen, China

Buying a new guitar in Shenzhen is not so easy as it might seem. Even though Shenzhen is one of the biggest cities in China it does not have a decent selection of guitar or music shops. There are two important places one should visit if you want to check or buy electric or acoustic guitars:

1. Shang bu lu. Right across the Shang Bu building. Exit A of Ke Xue Guan metro station. Music mall 3rd and 4th floor.

In these two floors you can find some acoustic guitar shops. The mainly sell Chinese brands and in the 4th floor there is an store selling electric and acoustic guitars in a single spot. In this store you may find pedals, some small amplifiers, cables, straps and related products. They mainly sell Strats, Squiers, Telecasters, and Epiphones. Their acoustic guitar selection is not so wide but they usually have sales for guitars that have been hanging on the wall for long time. They have a small recording/practice studio in the store that can be rented hourly and also have some guitar instructors if needed. The sales staff speak English, this is perfect because you can communicate without having to bring a Translator. They have a good selection of Joyo pedals. They do not sell pedal boards but do sell the power supplies and cables if you want to go DIY.

2. Sendy Music. In front of the SZ university south gate. You can take the 113 bus in Shennan road and it will drop you in front of the store.

This store is more professional and they even have tech support for your guitars. They sell small and mid range amps. I saw some Orange, Yamaha, Fender and Marshall amps. They sell American Tele and Starts. They have also Saga and Martin acoustic guitar at good prices. This store have Digitech, Boss, Joyo and Ibanez pedals at good prices and you can sit and ask the staff to help you check them one by one. They have some Ibanez and BC Rich guitars but I am not sure if the are made in The US. (Not too familiar with them) they also have some practice rooms for one to one lessons. The owner speaks English and is really thoughtful and friendly.

Both places are the biggest and best places to get your gear here in Shenzhen. You can find some smaller places but they lack the variety and quality one might be looking for.

Hope this info helps for those who want to explore and get some guitar gears.
