Hiking is (physically) healthy: it triggers anabolic growth of muscles and assorted other positive physical changes. You feel pleasantly tired at the end of the day, because assorted endorphins are released, as well. This is reality. This is the physical world the human animal was born into, evolved into.

ONTOLOGIES – BLOG LINAS Ontologies. David Chapman offers a critique of rationality at his meaningness.com site. Interesting reading. To define the word “ontology”, he offers up a rather striking list, a categorization of animals, from Jorge Luis Borges, from the Celestial Emporium of Benevolent Knowledge. The list is at first absurd, and humorous: OLD/OBSOLETE VERSION OF RAID AND DATA PROTECTION SOLUTIONS (Old, Obsolete version of) RAID and Data Storage Protection Solutions for Linux When a system administrator is first asked to provide a reliable, redundant means of protecting critical data on a server, RAID is usually the first term that comes to mind.

------------------------- THE HOME PAGE OF LINAS VEPSTAS Welcome to my home page! This page is (mostly) about me, or things I've done, or things that interest me, or other me-related things. Now that we've got that cleared up ... There's a lot of stuff here, some that I'm proud of, and some that I'm ashamed of. I could remove the shameful stuff. I won't. So its quasi-random assortment of stuff accumulated over the decades. Some of it might be entertaining. But probably not. A lot of stuff here was supposed to be useful for someone, back in the early days of the internet. That stuff is now hopelessly out-of-date. It will never be updated. The rest is a collection, ahem, cough cough, personal detritus and ephemera of an unstructured life pursuing whims without forethought, activities without planning. So, typical human-type stuff. Blog Linas is where it's at! Recent posts (in historical order):

I spend most of my on-line social time elsewhere. Even that has changed: it used to be my google+ page (where I spent a HUGE amount of time trying to find the weirdest and most eclectic stuff I could find; sadly, it has been totally whitewashed by algorithms, and become a wasteland of utterly boring monotonously homogeneous utterly uneventful, yet entirely acceptable tasteless, bland feed of porridge. Apparently, the google algorithms aren't able to discern my actual tastes. Is that good news, or bad news?). I don't have the energy to do this again on facebook . Oh well. Turns out that digital life is remarkably ephemeral. Rigor mortis is not just something cadavers do; so do web pages and social media feeds. You're looking at one now. Here's one that's still breathing: my Medium page . I really, really like the essays I wrote on Medium. Oh, wait, hang on -- that is because they are still mostly fresh. Just wait till they get old and rot a little bit. Who TF knew, back in 1995 or even 2005 that digital media could actually rot? Apparently, the process of life and living not only expects, but demands constant renewal. And with that in mind, I have a brand new Twitter account . Its got four posts so far, including the "hello twitter!" post. Hold on to your butts! Never mind. Forget Twitter. Secure scuttlebutt

is the place to be.

Some of my Medium posts that I like: * The Future of Humanity

* The Global Brain

* The Singularity and Your Place in It * Wild swings of beliefs — physics and sociology * Is Socialism Good? Some of my Medium posts that are more political, and make me cringe: * Cultural Relativism and Moral Authority * Free Speech on College Campuses * Meritocracy & White Male Culture Medium is .. frustrating. My profile page does not even list all of my essays! Its like... they're gone! WTF! Where are my essays? Arghhh!

Corporations!

Meanwhile, back in the past... I used to spend a lot of time on mailing lists, but all the good ones (like cypherpunks) have disappeared. Before that, there was the Ludwig Plutonium guy, and black helicopters, and men in black, and razor-wire detention camps in Arizona for space aliens and three-foot-tall people. All this to be found on the lovely nntp feed alt.conspiracy channel. It was truly an awesome time. For news feeds. I once wrote over 400 Wikipedia articles on Mathematics

(pictures too

) until that

stopped being fun.

This website? I don't feel like polishing this website to make it adhere to present-day website design sensibilities. This site isn't fresh. This website is a snapshot frozen in time: its what a personal website looked like in 1997, before blogs were invented.

* AUTO-BIOGRAPHY AND SELF-PROMOTION Let's begin. First, we start with an auto-hagiography and some self-promotion. Cause, like, you know, being employable and stuff like that means that y'gotta write in like, grammatically correct, fully formed and coherent sentences. And all that establishment b.s. You know the drill. So here we go! Here's my employability page on LinkedIn

. Wheeee!

Caution: boring sober bits ahead. At various times in my life, I've been a scientist, technologist and entrepreneur. I have broad interests in mathematics, physics, and computer technology. Oh, and sociology. And Art with a capital A. Oh, and lots of things, actually. Not enough lifetimes for them all. Many of my current technical interests focus on natural language

processing

and artificial general intelligence

. The

NLP directory has pre/re-prints of some of the academic publications that have come out of this work. My primary research platform is the open-source OpenCog project. For me, OpenCog provides a general technical setting where I can experiment with different machine learning theories and algorithms, with both connectionist and symbolic processing flavors. I've compiled a messy list of related open-source AGI projects here (which is now also hopelessly out of

date; so it goes.)

I've spent well over a decade at IBM ; most recently working on the Linux kernel for Power

architecture -based

mainframes . The Linux on the PowerPC wiki is a good place to find out more about IBM Linux mainframes and systems. I've been active in the Linux community; I was a founder of the Gnome Foundation ; and was the lead developer for GnuCash for over 7 years. I've founded three dot-com startups, all of which failed to turn me into an asshole billionaire. I mean the billionaire part; I'm an asshole, just not a rich one. I was a founding member of the OpenGL Architecture Review Board

; and

spent 8 years learning about and designing 3D graphics hardware and software. I have a PhD in theoretical physics

from SUNY at Stony

Brook . Currently,

I am utterly infatuated with mathematics , and have made large contributions to over 400 math articles in Wikipedia

. BTW, y'all,

global warming is for real. Do something about it. ------------------------- ------------------------- ------------------------- ------------------------- * VYTAUTAS O. VIRKAU MEMORIAL ARCHIVE Vytautas O. Virkau Memorial Archive. Vytas was my uncle. I loved him dearly. He passed away in 2017. I am trying to assemble an archive of his works and effects that I have in my possession. This is an ongoing

effort.

------------------------- * LINAS' MATHEMATICAL ART GALLERY A colorful exploration of some well-known, but under-examined equations. I think some of this is high Art, and much of the rest of it should be an eye-opener for even jaded fractal mathematicians. The Art Gallery has been running for over twenty-five years while being silent about the underlying math. I suppose its high time to make amends. The core idea of the dissertation is that the shapes of fractals are describable through Farey Fractions, which appear naturally through continued fractions, which have the symmetry of the Modular Group SL(2,Z), which is inter-twined with the Riemann Zeta and the structure of the set of rational numbers. Besides the four basic operations on the real numbers (addition, subtraction, multiplication, division), there is a fifth basic operation which is rarely taught in primary school and under-appreciated at higher levels, namely, "Farey Addition" or, expressed correctly, group multiplication in SL(2,Z). The modular group doesn't just lead to Pellian equations and algebraic numbers, it in fact intertwines all rational numbers (and their extensions to reals and p-adics) in crazy, fractal ways. This is why, for example, one sees Farey Fractions in the Mandelbrot Set. In number theory, the structure of the Modular Group provides a unifying theme for understanding the nature of factorization and primality. This is why, for example, power series and Dirichlet series (such as the Riemann Zeta) exhibit such crazy fractal Cantor-Set type patterns. Despite this connection being seen by Weierstrass as early as 1872, its more-or-less entirely ignored in standard textbooks on Analysis and Number Theory. A series of articles tries to provide some of the underpinnings for the above breathless assertions. Some highlights include: * DISTRIBUTIONS OF RATIONALS ON THE UNIT INTERVAL (OR, HOW TO (MIS)-COUNT RATIONALS) is a high-giggle-factor review of some so-called "facts" about fractions that you learned as a child, and which every math teacher ever since has repeated, but which are simply not true. I used to think Number Theory was boring until I saw this. * THE BERNOULLI MAP, THE GAUSS-KUZMIN-WIRSING OPERATOR AND THE RIEMANN ZETA reviews the basics of using the Frobenius-Perron Operator as a tool for studying fractals, and then applies it to to Bernoulli Map and the Gauss Map. Along the way, we discover that the eigenfunctions of the Bernoulli Operator are the given by the Hurwitz Zeta, and show the connection between them and the traditional fractal eigenfunctions. The details of the connection between the Riemann Zeta and the Gauss-Kuzmin-Wirsing (GKW) Operator are presented. A couple of exactly-solvable toy models of the GKW are presented as well. About half of this is a pedagogical introduction; the other half is a presentation of all-new results. * A SERIES REPRESENTATION FOR THE RIEMANN ZETA DERIVED FROM THE GAUSS-KUZMIN-WIRSING OPERATOR is a less rambling, more tightly focused extract of the above, meant for

publication.

* THE MINKOWSKI QUESTION MARK AND THE MODULAR GROUP SL(2,Z) shows that the distribution of Farey Fractions transforms under the dyadic representation of the Modular Group. It constructs the Minkowski Question Mark Function as a set-theoretic representation of (a subset of) the Modular Group. Reviews the hyperbolic rotations of binary trees. This paper provides the core background material for the structure of the Modular Group that is used in the other papers of this series. * SYMMETRIES OF PERIOD-DOUBLING MAPS identifies the Modular Group SL(2,Z) as the basic symmetry group of a large class of fractals. Although this relationship is obvious, it never ceases to amaze me that books on modular forms never mention fractals, and that books on fractals never mention modular forms, despite the obviousness of self-similarity of the Modular Group. Even Mandelbrot's most recent book, published in 2004, doesn't breath a word of this. This paper develops the Takagi or Blancmange Curve as a fractal curve that transforms under the three-dimensional representation of the Modular Group. It then shows how to build higher-dimensional representations out of the Bernoulli polynomials. * CONTINUED FRACTIONS AND GAPS provides a very curious function that is discontinuous on the rationals and whose discontinuities seem to be perfectly randomly distributed. I find this to be a rather dramatic result, possibly because I've never heard of such a thing before. I've stared at a lot of fractals and space-filling curves, but nothing like this. * ANNOTATIONS TO ABRAMOWITZ & STEGUN

includes a set of

annotations to the classic _Handbook of Mathematical Functions_, including new integrals over Bessel functions, and some sums over the Riemann Zeta function. * GAP THEORY develops some basic relationships between continued fractions, fractals and

Farey Numbers.

* Actually, I (now) know many fields of math, everything from string theory (well, affine Lie groups) to category theory, homology to mathematical logic, algebraic topology to differential geometry, quantum field theory and gravitation. And I'm proud of that. Don't believe me? Here's a list of over 400 WIKIPEDIA MATH ARTICLES

that I've edited;

you can check the revision history of these articles to see what I

wrote.

* POLITICAL, ECONOMIC AND SOCIAL SCREEDS Some short essays that seemed to be important to write, during the first decade of the 2000's. These are ... of a certain bygone era. Most of these are just sly, corrosive expressions of anger and hostility, lashing out at events beyond my control.

*

AMERICAN POLITICAL UNREALITY, 2008 . Yes, politicians are from outer space, and they arrived in a flying saucer called "journalism". How can you tell? They focus on everything except what is _actually_ important.

*

Why did Bush promote warrant-less wiretapping? Why is Obama continuing these Bush policies? I can guess why, and I really don't like it. STOP

ILLEGAL SPYING! .

WIKIPEDIA NEEDS NEW LEADERSHIP! I _used_ to have various essays

about the

structural and cultural problems in Wikipedia, and the things that could be done to solve them. These were posted on my WP user page . Unfortunately, the malicious and stupid leadership there found these so offensive that they deleted the essays. Boo-yah! So now my profile is just _soo_ very squeaky-clean and totally inoffensive. To anyone, that is, except me. You might never guess that I'd been raped by the admins there. Woo

hoo! Go Wikipedia!

LABOUR OF LOVE - THE VOLUNTEER ECONOMY Free-market economists, thinkers and pundits (correctly) champion the power of free markets to create a better world. Yet if one opens a history book, it is hard to find a historical figure that was motivated by greed. Both prominent and emerging social and economic institutions are marked by excellence due volunteer, freely donated efforts, rather than wealth accumulation. When will we recognize the economic benefits of channelling this powerful force with social, political and governmental norms?

*

FREE SOFTWARE ~ FREE TRADE? An examination of the powerful economic forces driving the acceptance of Free Software/Open Source in corporations and businesses. When we realize that Free Software is not just a (political) philosophy, or a social or anthropological movement, but an economic force akin to the removal of trade barriers, we can finally understand why its adoption by corporations promises to be a sea-change in the way that software is used. Reviews a business case study of a very large, failed technology project. If you thought the Internet was big ... this is bigger.

BANNED! A collection of outlaw computer technology, harvested from the net. Why would I mirror such dangerous and subversive material? In order to protect my personal freedoms -- and yours. Seems that greed and lust for power -- happily wrapped in the flags of "free enterprise" and "democracy", continue to lie at the root of many political and social evils and ills. * LINUX ENTERPRISE COMPUTING A snapshot of what Linux tech looked like in the late 1990's. I was very, very interested in promoting Linux in the business world, back then. I wanted it to succeed wildly! (And it did!) These pages attempted to provide a compendium of references, resources and a guide to prominent Free Software systems and technologies, from the corporate computing perspective. Topics include: * LINUX PROJECT MANAGEMENT AND BUG TRACKING TOOLS. * SQL AND OTHER DATABASES FOR LINUX. * LINUX RAID SOLUTIONS. * LINUX NETWORK ADDRESS TRANSLATION SOLUTIONS. * LINUX SOFTWARE RAID HOWTO. * NETWORK MANAGEMENT TOOLS FOR LINUX. * LINUX X.25 AND FRAME RELAY PRODUCTS AND VENDORS. * LINUX CLUSTER, PARALLEL & MULTI PROCESSING INFO. * ISDN TO ETHERNET BRIDGE/ROUTER INFO (& OTHER ISDN INFO) * MY FREE SOFTWARE PROJECTS I've worked on many free software projects. Below are some of my favorites, with a more complete list here . My Ohloh account provides details and statistics for some of my more recent, active projects. * The OPENCOG PROJECT aims to build a free, open-source artificial general intelligence. Tall order. We've barely scratched the surface. * The CMU LINK GRAMMAR PARSER

is a natural

language parser. Its English-language dictionary contains over 70K words, and it is a pretty powerful and robust system. I've fixed a many bugs in it, expanded parse coverage significantly, and even hacked a quickie Lithuanian grammar for it: linkparser> Atvažiavom į sodžių. Found 1 linkage (1 had no P.P. violations) Unique linkage, cost vector = (UNUSED=0 DIS=0 AND=0 LEN=1)

+----LI----+

|     +-DG-+-Xp-+ |     |    |    | atvažiavom į sodžių  . * RELEX is a semantic relationship extractor for the English language. It is built on top of the CMU Link Grammar Parser, and outputs a semantic feature graph of parsed sentences. I didn't create RelEx, but I extended bits and pieces of

it.

* GNOTIME , the Gnome Time Tracking Tool. A desktop to-do list utility for tracking how much time you've spent working on a project. Includes a flexible invoice generator for billing clients for time & services. * ESA/390 LINUX Linux on a mainframe? You bet your booties. No, this is not a stupid trick; the Mainframes is the most powerful and advanced CPU architecture on the planet, and it makes sense to put Linux on it. As a practical matter, Linux on the mainframe can bring the cost of computing down to a level below other high-end Unix platforms from Sun, SGI and HP. Of theoretical interest, the extension of some of the principles of VM to Unix systems in general could greatly and fundamentally alter ideas about computer security, partitioning and performance. This is not

your father's MVS.

* GCC/EGCS -- the mainframe i370 back end for the gcc compiler, used to port the Linux kernel to the mainframe (above). * BINUTILS -- the mainframe i370 back end for the gas assembler, used to port the Linux kernel to the mainframe (above). * THE GNUCASH PERSONAL FINANCE MANAGER This is the biggest project I've ever worked on, and you can say I started it. I started by fixing a few bugs in a small piece of software called "X-Accountant", back in '96 or '97. Since then, I've put in thousands of hours of work into this software (yes, that's full time, overtime, evenings and weekends, for many years). Along the way, the name changed to "GnuCash", and its had hundreds of volunteers adding features functions, documentation and translations, turning GnuCash into the leading personal finance management software on Linux today. Its now included in all major Linux distributions, and sees downloads in the tens-of-thousands whenever a new version is released. * XBAE -- a free table widget for Motif. Full-featured, quite

functional.

* GLE -- The GLE Tubing and Extrusion library. Draws three-dimensional polycylinders, polycones, surfaces of revolution and other shapes, using the OpenGL 3D graphics library. * MAY -- a distributed processing infrastructure (obsolete). Allows worker processes to be automatically launched on remote computers, data to be parcelled out to them, and the results of the computations to be collected. Used to implement a distributed (3D graphics) ray-tracer, and also a distributed (3D graphics) radiosity

algorithm solver.

* TECHNICAL RUMINATIONS Miscellaneous technical articles and notes.

*

A BETTER WAY TO DO SETI makes the argument that if extra-terrestrials are trying to send us a radio message, then they will be using broadband spread-spectrum (pseudo-random noise) modulation techniques. Finding such a signal is much, much harder, but when found, it provides a much, much clearer communications channel than any other modulation technique. The ET's know this, and they know that we know this, and will thus use this technique preferentially. Essentially all of the current SETI searches, while being important so as to rule out other methods, are all really looking for the wrong

thing.

*

ETERNITY SERVICE is a commentary on the basic ideas behind Napster as viewed through the eyes of David Gelertner. David chooses not to dirty his prognostications with the names of present-day technologies. I do. They are E-Rights, distributed.net, and Eternity Service, all mashed into one.

A DIGRESSION ON ARTIFICIAL LIFE AND CELLULAR AUTOMATA This web page is a very long diary of a set of experiments that were run in the early 90's with a collection of cellular automata. The automata were designed to have a 'genetic code' that was shared between cooperating individuals. By cooperating (or not) individual cells could (and did) self-organize into 'symbiotic' plant-like structures. Lots of interesting stuff was seen. Never attempted to write this up for publication; I should have. Nuts. * PHILOSOPHICAL RUMINATIONS Sophomoric, half-baked, incoherent, nutty ideas, most of which have probably already been better-expressed in some top-ten selling book. These include, but are

not limited to:

* THE ORIGINS OF QUANTUM MECHANICS An attempt to re-derive QM (and GR+QFT) from first principles. I like to think of the present as a wave-front where the liquid future freezes into a solid past. Mathematically, the past is a sheaf or a topos, the future is a pre-sheaf, not yet glued together, and the gluing axioms happen at the surface of light-cones. QM is that fluid thing that lives near the present, where space-time itself is being glued together; the indeterminacy of QM is the not-yet-glued-ness. Or something like that. This and many other ideas and possibilities are explored. * THE ORIGIN OF TIME, QUANTUM MECHANICS, AND FREE WILL A nutty digression that asserts that quantum mechanics is a side-effect of Planck-scale physics, rather than

something innate.

* IN THE BEGINNING WAS THE WORD An unfinished defense of the Platonic Interpretation of Mathematics. Mathematics does not exist solely in the heads of humans, but in and of itself. Indeed, even the almighty God does not have the power to change the value of Pi (which, I believe, is a statement about God,

and not about Pi).

* A DIGRESSION ON THE NON-COMPUTABILITY OF THOUGHT Something about incoherent, irrational clocks powering parallel Turing machines. * FREE WILL AND DETERMINISM An very weak (and ultimately failed) attempt to disentangle free will and consciousness from physical (Newtonian) determinism. * HEIDEGGER'S FUNDAMENTAL QUESTION , some sophomoric notes. Ties together some of the essays above. * MY WEBLOG This is the output of my new experimental note-taking and publishing and general-diary tool, GnoTime . We'll see how easy, scalable, effective this tool really is. Or, how dis-interested I am in using it

...

The good stuff is in the form of letters: * Letter from Sofia, Bulgaria, August 1997 * Letter from Sofia, Bulgaria, September 1997 * Letter from Vilnius, Lithuania, August 2004 * EMPLOYMENT HISTORY References pertaining to the various jobs I've held, and what I did while I worked there.

AN AIRLINE FLIGHT RESERVATION SYSTEM I founded Teleport Travel, and was bought out by Intransco, where I served as Chief Technology Officer. More work, for less money, at an Internet startup. Developed the prototype entirely by myself. Teleport Travel was the very first on the 'net (Spring/Summer 1995) with an actual functioning airline reservation system, never mind that it worked better, and had a nicer user interface than many/most travel res systems today. An unhappy experience in the end, as this was a dot-com that dot-bombed. I shoulda been a billionaire by now, but it turns out (duhh) that superior technology has no correlation to success. Its all about the management, the CEO, the board of directors. I was unable to control the company, and was bitter about it for a long time -- my baby was taken away from me. Anyway, the actual technology does live on at TravelStoreMaker.com , and some good friends still work

there.

OPENGL AND VRML

. I worked at IBM as the OpenGL(tm) architect for many years, participating in a variety of technical and marketing activities surrounding the RS/6000 hardware, operating system software, and 3D graphics subsystem. Besides creating the above web pages in a fit of marketing mania, I've written some technical articles: * Extending VRML for Panoramic Images * Software OpenGL: Architecture and Implementation * Programming in OpenGL * Integration of GL with the X Window System * FORMAL SCHOOLING I was lucky, and got a very good education.

UNIVERSITY OF CHICAGO AB Physics. Class of `80. I was ranked third, out of a class of about 50. The kid who was ranked first was home-schooled, and was maybe about 16 when he got his degree. He did not attend classes with us; we never laid eyes on him. I wonder if he grew up famous, or not. Which made me the youngest, attending regular classes. I was 20 when I finished college. A girl was ranked second. I wish I could remember her name. I'd like to talk to her. The list itself is lost in the sands of time.
