Hi, I am yaspr, an engineer, and this website serves as a sanctuary for those seeking depth and understanding. My primary goal is to delve into the core of various highly technical subjects, including compilers, cryptography, networking, image processing, and operating systems, all the way down to low-level code optimizations and micro-architectural benchmarking. Here, you will discover a selection of technical articles and resources aiming at assisting you on your journey toward mastery of the computer design and programming disciplines.

Given my background (which I will keep undisclosed), I am a fervent advocate for privacy and the fundamental right to freedom from all forms of ideological oppression. Let me be unequivocal: I vehemently oppose mass surveillance, the dominance of certain governments, the wealthy "elite", their capitalist agendas, and their insidious subliminal propaganda. As a humanist, I reject any ideology, action, argument, or opinion that permits the violation or belittlement of fellow humans. If you believe you are somehow exceptional or chosen by a higher power to lead, guide, rule, or impose any so-called "divine" ideology, let me be clear: first, FUCK YOU; second, confront your hero/messianic complex before it wreaks havoc. Moreover, if you find yourself idolizing any figure -be they actors, musicians, authors, politicians, or mythical/religious icons- I urge you to take a moment for introspection and reevaluate your values within the context of the vast universe. No one and nothing deserves to be idolized.

This said, I am not an angry pessimist. I firmly believe that selflessness, kindness, compassion, openness, benevolence, equal opportunity, and the sharing of knowledge and skills are the most effective pathways toward an equanimous humanity. I also stand resolutely against the relentless propaganda machine of the obscurantist "elite" and their psychopathic followers, whose sole aim is to distort our perception of reality, sow division, and occult the truth for their own selfish material and social gains. This insidious influence must be challenged, and their power dismantled entirely. When I refer to the "elite", I do not mean a shadowy government cabal, a superior alien race secretly colluding with the U.S. government to hide advanced technology in Area 51, or any specific family -such conspiratorial nonsense is utterly unproductive and a total waste of intellect. Instead, I am speaking of the corrupt politicians, their pseudo-intellectual allies, the fearmongering media conglomerates, and the avaricious corporations that perpetuate and profit from human exploitation.

From my perspective, the key to achieve liberation from the shackles of ignorance lies in curiosity, openness, education, and introspection. If we, the inhabitants of this planet, choose to reject the control of these hypocritical overlords and their inhumane agendas, we can forge a path toward a more collaborative and blissful future.

If you are a musician and/or just someone who enjoys listening to the peregrinations of musicians, you'll find some of my tracks below.

NO SLAVES, NO MASTERS!! Enjoy ;)

My musical sketches/ideas

I have been immersed in music since childhood, mastering multiple instruments and exploring a diverse array of styles. Yet, at my core, I will always be a metalhead \m/. I abhore commercial music, which often lacks depth, taste, and novelty, though I recognize the talent and the incredible musicianship that goes into its production. I generally record everything by myself at home using Audacity on Linux and I mix everything up after selecting the takes that best capture my vision. As for my gear, I play an Alesis Nitro kit for drums -modified to include a double bass, a feat I could write a whole article about- loaded with different samples on an SD card. For guitar, I use an Epiphone Les Paul and a Telecaster, with primarily a Zoom G3 for effects, along with some of my own pedals. The bass is a Fender Precision, and I mix everything through a Yamaha AG06 console paired with a Behringer Henyx 1202. So, while my setup is not extravagant, it gets the job done!

If I were to list the bands and musicians that have influenced me the most, it would include: Annihilator, Slayer, Tool, Lamb of God, Pantera, Damageplan, Black Label Society, Spliknot, Plini, Kreator, Meshuggah, Metallica, Megadeth, God Is An Astronaut, Porcupine Tree, Tigran Hamasyan, Charlie Parker, Duke Ellington, Dhafer Youssef, Hania Rani, Hiromi Uehara, Norah Jones, Chick Corea, Al Di Meola, Guthrie Govan, Steve Vai, Paco de Lucia, Zakariyya Ahmad, Mohamed el-Qasabgi, Yanni, Mohamed Abdel Wahab, Animals As Leaders, Infected Mushroom, Shpongle, and a zillion others.

Below is a short sample of some of my explorations and peregrinations. I hope you enjoy it!
