I am a postdoctoral researcher in professor Frauke Gräter's Molecular Biomechanics (MBM) group at Heidelberg Institute for Theoretical Studies (HITS). I am participating in development of free and open source software we use. Previously, I was a postdoctoral researcher in professor Željko Svedružić's laboratory crew. I was studying molecular modelling of biomolecules. I was concentrated on investigating reaction dynamics of protein-ligand interactions with molecular dynamics and nudged elastic band methods using quantum chemistry and QM/MM approaches.
I have done my PhD work in professor Branko Mikac's research group at University of Zagreb Faculty of Electrical Engineering and Computing (FER) Department of Telecommunications. My PhD research work has been focused on evaluation of optical telecommunication network reliability and availability using Monte Carlo method and optimization of routing and wavelength assignment.
I am also interested in applications that use heterogeneous parallel and distributed computing and run on high performance computers. In particular, I was focused on parallel execution of network simulation software as a part of the PhD work described above.
At InfUniRi I TA the courses:
I also TA'd Computer Networks 1 until 2015 and Operating Systems 1 until 2012. At RiTeh I TA'd Computer Networks course on undergraduate level in 2013 and 2014.
At BioTechUniRi I teach Informatics and TA Chemoinformatics courses on undergraduate level. On master's level, I teach Physical Organic and Computational Chemistry and TA Design of Biologically Active Molecules by Computational Methods courses.
Teaching materials can be found at reStructuredHgWiki (in Croatian, licensed under CC-BY-SA 4.0, source code available). Auditory exercises for Computer Networks are not part of reStructuredHgWiki and are available in a separate repository.
I am one of the developers of ns-3 network simulator. In particular, I am a developer of optical telecommunication network model (source code available). Parts of it utilize Open MPI and NVIDIA CUDA. (Feel free to contact me for more information.)
Among other projects, I have contributed patches to LLVM, CP2K, and GROMACS (detailed summary of my contributions can be found on OpenHub). Prior to contributing patches to these open source projects, I was a tester and web standards advocate for Mozilla and also tester and support for kX Project, an alternative driver for Sound Blaster Live! and Audigy cards developed to expand the potential of the EMU10kX DSPs.
I am a big fan of Debian GNU/Linux and Fedora distributions (their quality and their emphasis on software freedom are first class), NetBeans and Eclipse IDEs, Clang C/C++/OpenCL and GFortran Fortran compilers, Git version control system, LaTeX, ConTeXt, and reStructuredText markup formats (because of high quality of TeX Live and Sphinx, respectively).
Less specifically, I am very happy how LibreOffice is going forward and I enjoy promoting it along with OpenDocument, an open standard format for office documents. Even less specifically, I regularly advocate usage and development of free and open source software (FOSS) and I am glad to see how successful this movement has become.
Finally, I stand for individual freedom which is constantly under threat from pervasive surveillance and unrestrained authoritarian governments. I appreciate and support the work of Electronic Frontier Foundation in this area.

"The present state of the world is not the proof of philosophy’s impotence, but the proof of philosophy’s power. It is philosophy that has brought men to this state – it is only philosophy that can lead them out."
(For the New Intellectual)
"But you see, I have, let's say, sixty years to live. Most of that time will be spent working. I've chosen the work I want to do. If I find no joy in it, then I'm only condemning myself to sixty years of torture. And I can find the joy only if I do my work in the best way possible to me. But the best is a matter of standards—and I set my own standards. I inherit nothing. I stand at the end of no tradition. I may, perhaps, stand at the beginning of one."
"[B]efore you can do things for people, you must be the kind of man who can get things done. But to get things done, you must love the doing, not the secondary consequences."
"The machine, the frozen form of a living intelligence, is the power that expands the potential of your life by raising the productivity of your time. If you worked as a blacksmith in the mystics’ Middle Ages, the whole of your earning capacity would consist of an iron bar produced by your hands in days and days of effort."
"Man's mind is his basic tool of survival. Life is given to him, survival is not. His body is given to him, its sustenance is not. His mind is given to him, its content is not. To remain alive, he must act, and before he can act he must know the nature and purpose of his action. He cannot obtain his food without a knowledge of food and of the way to obtain it. He cannot dig a ditch – or build a cyclotron – without a knowledge of his aim and of the means to achieve it. To remain alive, he must think."
"If you choose to deal with men by means of compulsion, do so. But you will discover that you need the voluntary co-operation of your victims, in many more ways than you can see at present. And your victims should discover that it is their own volition – which you cannot force – that makes you possible. I choose to be consistent and I will obey you in the manner you demand. Whatever you wish me to do, I will do it at the point of a gun. If you sentence me to jail, you will have to send armed men to carry me there – I will not volunteer to move. If you fine me, you will have to seize my property to collect the fine – I will not volunteer to pay it. If you believe that you have the right to force me – use your guns openly. I will not help you to disguise the nature of your action."
"I want to see, real, living, and in the hours of my own days, that glory I create as an illusion. I want it real. I want to know that there is someone, somewhere, who wants it, too. Or else what is the use of seeing it, and working, and burning oneself for an impossible vision? A spirit, too, needs fuel. It can run dry."
(Introduction to 25th Anniversary Edition of The Fountainhead)
"People do it everyday, they talk to themselves... they see themselves as they’d like to be, they don’t have the courage you have, to just run with it."
"I say never be complete. I say stop being perfect. I say let's evolve. Let the chips fall where they may."
"Leonardo's Mona Lisa is just a thousand thousand smears of paint. Michelangelo's David is just a million hits with a hammer. We're all of us a million bits put together the right way."
"We're the middle children of history, man. No purpose or place. We have no Great War. No Great Depression. Our great war is a spiritual war. Our great depression is our lives. We've all been raised on television to believe that one day we'd all be millionaires, and movie gods, and rock stars, but we won't."
"We're consumers. We are by-products of a lifestyle obsession. Murder, crime, poverty, these things don't concern me. What concerns me are celebrity magazines, television with 500 channels, some guy's name on my underwear. Rogaine, Viagra, Olestra."
"Old George Orwell got it backward. Big Brother isn't watching. He's singing and dancing. He's pulling rabbits out of a hat. Big Brother’s busy holding your attention every moment you're awake. He's making sure you're always distracted. He's making sure you're fully absorbed. He's making sure your imagination withers. Until it's as useful as your appendix. He's making sure your attention is always filled. And this being fed, it's worse than being watched."

"Science is woefully underfunded compared to the scale of the problems it’s trying to solve."
"As an adolescent I aspired to lasting fame, I craved factual certainty, and I thirsted for a meaningful vision of human life – so I became a scientist. This is like becoming an archbishop so you can meet girls."
"Technology leadership is not defined by patents, which history has repeatedly shown to be small protection indeed against a determined competitor, but rather by the ability of a company to attract and motivate the world’s most talented engineers. We believe that applying the open source philosophy to our patents will strengthen rather than diminish Tesla’s position in this regard."
(All Our Patent Are Belong To You by Elon Musk)
"You and I are told increasingly that we have to choose between a left or right, but I would like to suggest that there is no such thing as a left or right. There is only an up or down – up to a man's age-old dream; the ultimate in individual freedom consistent with law and order – or down to the ant heap of totalitarianism, and regardless of their sincerity, their humanitarian motives, those who would trade our freedom for security have embarked on this downward course."
(A Time for Choosing by Ronald Reagan)
"Those who seek absolute power, even though they seek it to do what they regard as good, are simply demanding the right to enforce their own version of heaven on earth. And let me remind you, they are the very ones who always create the most hellish tyrannies. Absolute power does corrupt, and those who seek it must be suspect and must be opposed. Their mistaken course stems from false notions of equality, ladies and gentlemen. Equality, rightly understood, as our founding fathers understood it, leads to liberty and to the emancipation of creative differences. Wrongly understood, as it has been so tragically in our time, it leads first to conformity and then to despotism."
(1964 Acceptance Speech as the Republican Presidential candidate by Barry Goldwater)
"An empire replacing the republic. Slavery sold as liberty. Excellence and virtue traded for mediocrity. Socalism to save capitalism. A government out of control, unstrained by the constitution, the rule of law or morality. Bickering over petty politics as we descend into chaos. The philosophy that destroys us is not even defined. We have broken from reality a psychotic nation. Ignorance with a pretense of knowledge replacing wisdom. Money does not grow on trees, nor does prosperity come from a government printing press or escalating deficits. We are now in the midst of unlimited spending of the people’s money. Exorbitant taxation, deficits of trillions of dollars spent on a failed welfare-warfare system. An epidemic of cronyism. Unlimited supplies of paper money equated with wealth. A central bank that deliberately destroys the value of the currency in secrecy, without restraint, without nary a whimper, yet cheered on by the pseudo-capitalists of Wall Street, the military-industrial complex, and Detroit."
(Current Conditions or Just a Bad Dream? by Ron Paul)
"[S]ociety was never so much about ideal distribution of resources, as it was about the centralized use of force vs a decentralized voluntary trade and resilience to such force. The Internet and blockchain technology is the best promise of decentralized resilience we've had in 500 years."
(It was never about capitalism vs communism - it was always about centralized vs decentralized by Rich Falkvinge)
"Where equality is enthroned, freedom is extinguished. The rise of the egalitarian society means the death of the free society."
(Suicide of a Superpower by Pat Buchanan)
"You send your kids off to college. They love you. You walk away with a Cornell mom T-shirt. You are walking away going this is great, and come Thanksgiving, your kid tells you that you are an imperialist and a racist and a homophobe. That is not worth $120,000."
(Andrew Breitbart speaking at Council for National Policy)
"The future of technology is not pre-determined, and we must resist the temptation of technological utopianism – the notion that technology has a momentum or will of its own, that it will guarantee a more free future, and therefore that we can ignore the terrible arc of the political in our world. A better metaphor is that we are in a deadly race between politics and technology. The future will be much better or much worse, but the question of the future remains very open indeed. We do not know exactly how close this race is, but I suspect that it may be very close, even down to the wire. Unlike the world of politics, in the world of technology the choices of individuals may still be paramount. The fate of our world may depend on the effort of a single person who builds or propagates the machinery of freedom that makes the world safe for capitalism."
(The Education of a Libertarian by Peter Thiel)
"Technology revolutionaries succeeded not because of some collectivist vision that seeks to regulate “fairness”, “neutrality”, “privacy” or “competition” through coercive state actions, or that views the Internet and technology as a vast commons that must be freely available to all, but rather because of the same belief as America’s Founders who understood that private property is the foundation of prosperity and freedom itself. Technology revolutionaries succeed because of the decentralized nature of the Internet, which defies government control. As a consequence, decentralization has unlocked individual self-empowerment, entrepreneurialism, creativity, innovation and the creation of new markets in ways never before imagined in human history... Around the world, the real threat to Internet freedom comes not from bad people or inefficient markets – we can and will always route around them – but from governments' foolish attempts to manage and control innovation. And it is not just the tyrannies we must fear. The road away from freedom is paved with good intentions."
"I will not serve that in which I no longer believe, whether it call itself my home, my fatherland, or my church: and I will try to express myself in some mode of life or art as freely as I can and as wholly as I can, using for my defence the only arms I allow myself to use – silence, exile and cunning."
(A Portrait of the Artist as a Young Man by James Joyce)
"The human race is but a monotonous affair. Most of them labor the greater part of their time for mere subsistence; and the scanty portion of freedom which remains to them so troubles them that they use every exertion to get rid of it."

"The world you're looking at only exists from the outside. The only reason I survive in it is that I always knew it was empty."

"Every revolution was first a thought in one man's mind and when the same thought occurs in another man, it is the key to that era."

"Svršeni su računi ove godine. Bila je crna po nas Hrvate. Dobrote ne doživismo nikakove, zla i premnogo. Kiša i tuča, poplava poharala zemlju... 9. studenoga ošinu nas strahoviti potres te uništi u našem liepom Zagrebu mnogo liepih nada. Ne samo ljudi, ne samo Madjari i Austrijanci, i narav se proti nama urotila, sve zlo je navalilo na nas biedne Hrvate. Hoće li bolje biti? Mora jedan put, ta gore ne može biti nego što je sada. Da se ta crna godina i ljuto završi, padala je danas u Zagrebu tuča. Vrieme je toplo, vlažno kao u proljeće, sniegu ni traga. Mi stojimo moralno i materijalno u blatu. Hoće li Bog tome biednome narodu ikada pomoći? – upitah se često za ovih zadnjih dana godine. Čovjek gotovo da sdvoji, toliko se pojavilo kod nas kukavica, toliko ništarija i propalica, toliko ima lopovštine, da te groza hvata. Poštenje, dosljednost, karakter dan-danas su kod nas gotovo suvišni pojavi."

My surname Miletić is pronounced as Miletich with ch as in "cheers" and "cherry". This ending perfectly fits Switzerland's .ch domain for domain hack; a domain hack is basically anything like youtu.be, n.pr, sptnkne.ws, goo.gl, cr.yp.to, igraoni.ca, ga.me, ma.tt and, of course, nudgedelastic.band (see domai.nr for more). I find domain hacks very cool, think of them as an expression of personal creativity, and also like Switzerland a lot; hence vedranmileti.ch.
From 2007 till 2009, while I was still an undergraduate student of mathematics, my personal site was located on www.ffri.hr/~vmiletic. In 2009, when I got employed by Department of Informatics, the site moved to www.inf.uniri.hr/~vmiletic. For a while I was reluctant about getting my own domain; I considered various options using .com and .hr (including vedranmiletic.from.hr) but didn't really like any of them. In 2014, after expanding my search on ccTLDs other than Croatian one, I finally thought of using .ch domain hack and from the start vedranmileti.ch felt just right. Right now, all of these domains are redirected to vedran.miletic.net for consistency with the rest of the Miletić family.
My brother Mladen prefers ordinary (i.e. non-hack) domain names and has chosen mladen.miletic.net for his professional site (miletic.net is our family domain). There is another Mladen whose work I admire, Mladen Šarić, a fashion photographer.
The name Vedran comes from Croatian vedri dan which translates to English clear day. The surname Miletić has no particular meaning that I am aware of; despite, my father always joked and made stories around leti part which translates to fly (verb). Is it written down as Miletić, Miletic or Miletich? I am okay with any of these. Research papers indexed in databases mostly contain the non-accented version (i.e. Miletic), because the accented version (i.e. Miletić) can be hard to write on any keyboard layout other than Croatian. Fun fact: there's another Vedran Miletić I know and he's doing very nice 3D Origami.
