The Case for D / By Andrei Alexandrescu
Source: http://www.drdobbs.com/high-performance-computing/217801225;jsessionid=552NPNXL1LY5NQE1GHPSKHWATMY32JVN
There are two major versions of the language -- D1 and D2. This article focuses on D2 exclusively. D1 is stable (will undergo no other changes but bug fixes), and D2 is a major revision of the language that sacrificed some backwards compatibility for the sake of doing things consistently right, and for adding a few crucial features related to manycores and generic programming. In the process, the language's complexity has increased, which is in fact a good indicator because no language in actual use has ever gotten smaller. Even languages that started with the stated intent to be "small and beautiful" inevitably grew with use. (Yes, even Lisp. Spare me.) Although programmers dream of the idea of small, simple languages, when they wake up they seem to only want more modeling power. D's state of transition is putting yours truly in the unenviable position of dealing with a moving target. I opted for writing an article that ages nicely at the expense of being occasionally frustrating in that it describes features that are in the works or are incompletely implemented.

How to manage SCSI harddisks on Solaris / UNIX
I love SCSI harddisks for their reliability and speed. If the environment is not extreme and the cooling is proper they can work 24/7 for years.
Eventhough happens from time to time that some harddisks fail, some needs to be changed, or some configurations simply began to display errors like: MAGIC NUMBER WRONG.
0. To start with, I would first run the fsck utility to check for any inconsistency and where is this located.
Run: fsck -y
This will run through the list of /etc/vfstab harddisks entries and slices and will display something like:
blue # fsck /dev/rdsk/c0t2d0s6
** /dev/rdsk/c0t2d0s6
** Last Mounted on
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
2 files, 9 used, 70420729 free (9 frags, 8802590 blocks, 0.0% fragmentation)
** /dev/rdsk/c0t2d0s6
BAD SUPER BLOCK: MAGIC NUMBER WRONG
USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
eg. fsck [-F ufs] -o b=# [special ...]
where # is the alternate super block. SEE fsck_ufs(1M).
Or if anything wrong then something like will output the errors.
1. If a new HD was added I would boot with the option to reconfigure:
boot -r
You can also check the boot messages here:
vi /var/adm/messages
2. Verify the /etc/vfstab file and /etc/mnttab files.
In order to do a clean repair but still the server to be useable, I would munt/unmount from these files.
3. Use the format utility to check more in detail the status of the harddisks.
For example I run the read tests often. Also from format it is possible to configure partitions, etc.
After a configuration was made, from format use also the label, to write the changes.
If the harddisk is new, and configured the partitions with the format utility you need to create also the new filesystem on the slices:
Ex: newfs /dev/rdsk/c0t1d0s6
4. Modifiy the /etc/vfstab and add the newly created slices to it. Also create mount entries on the /etc/mnttab file:
blue # mkdir /files0
blue # mount /files0
blue # df -a /files0
This will return the mount point created.

Josh Bloch on the Future of Java
Source: http://www.infoq.com/news/2010/04/bloch_java_future
A Discussion with Josh Bloch on the Future of Java
Josh Bloch - a prominent contributor (you might know some of his work if you've ever used the Java Collections framework) to the Java platform at Sun for many years, currently a Googler, author of the award winning books "Effective Java" and "Effective Java Second Edition" - gave a talk at the recent web-based Red Hat Middleware 2020 conference. The thrust of the talk was guarded optimism and concern about the future of the Java platform under Oracle's stewardship. InfoQ contacted Josh to see if he would be interested in expanding upon these ideas. The discussion - particularly apropos of the increasing exodus of Sun talent from Oracle and concerns over Oracle's handling of the community and the Java Intellectual Property looming - is reaching a fever-pitch of late because it intersects many different, going concerns. We were glad to be able to talk to Mr. Bloch about some of these.
InfoQ : What is your main concern?
I don't have a single main concern. Several factors that have combined in the past few years to take the wind out of Java's sails.
InfoQ: Why do you feel the march of evolution for Java has slowed?
- The Sun / Apache stalemate TCK licensing stalemate has all but eliminated progress via the JCP.
- Sun's lack of support, leadership, and clarity has kept Java 7 from making perceptible progress. I'm not sure people are aware how few resources Sun allocated to Java SE in the past few years. But the consequences have been quite visible: every year JavaOne rolls around, and Java 7 seems no closer. And there has been an awful lot of infighting among Java's supporters. In earlier days, Sun played the role of benevolent dictator, which helped to limit the infighting.
- The use of GPLv2 for OpenJDK hinders adoption even by those who are less concerned with TCK issues. The "copyleft" provisions scare away many potential corporate adopters. As a result, resources are being split between Harmony and OpenJDK. Also the multiplicity of license used by the various JCP members for various components of various standards is just plain confusing. In effect, it places a tax on Java platform development
InfoQ: How can racle better the situation where Sun couldn't?
Oracle has historically supported JCP reforms that would end the stalemate. Also they are in better financial shape than Sun was, so they can afford to reinvigorate the platform and they've publicly declared their intention to do so. Finally, with a changing of the guard, some historical baggage can be jettisoned. Where Sun might have seen certain changes as unpalatable, Oracle might look at the situation with fresh eyes and say "why not?"
InfoQ: Is this all strictly related to the morass of licensing issues?
No; licensing issues play a major role, but it goes beyond that. As I said before, there has been a lack of resources, leadership, and focus.
InfoQ: Is the situation surrounding the Apache Harmony project, which is in turn also used as the basis for the Android libraries, an acceptable one? (Ed: Harmony struggled with Sun over the TCK license well before Google adopted Harmony as the basis for the Android libraries. Google's decision to use Harmony rather than the OpenJDK libraries has less to do with the Harmony TCK licensing dispute than with Sun's decision to use GPLv2 for OpenJDK. Google's partners wouldn't agree to redistribute it without a more permissive license. The Apache group was at one point offered a qualified TCK license, but rejected it because the field-of-use restrictions were unacceptable to Apache and the JCP EC who believed them to violate the JCP agreement.)
No. As I said before, it stands in the way of the health and progress of the platform. Also it is causing companies to waste tremendous amounts of engineering effort, splitting their resources needlessly between Harmony and OpenJDK.
InfoQ: How would you like to see Oracle react to things like Harmony?
I would like to see them enact the resolution they proposed at the JCP EC Meeting of December 12, 2007:Resolution 1 (proposed by Oracle, seconded by BEA)
"It is the sense of the Executive Committee that the JCP become an open independent vendor-neutral Standards Organization where all members participate on a level playing field with the following characteristics:
- members fund development and management expenses
- a legal entity with by-laws, governing body, membership, etc.
- a new, simplified, IPR Policy that permits the broadest number of implementations
- stringent compatibility requirements
- dedicated to promoting the Java programming model
Furthermore, the EC shall put a plan in place to make such transition as soon as practical with minimal disruption to the Java Community."
As for the "new, simplified IPR Policy," I believe it would be highly beneficial to the entire community if a widely accepted permissive open source license such as Apache or BSD were adopted for all components of all Java specs.
InfoQ: What do you see as Oracle's role?
I would dearly love to see them reclaim Sun's role as leader and steward of the Java platform. Of course things will be a bit different now, because the world has changed. Other organizations will contribute more resources and share more control.
InfoQ: For that matter, how do you think things like Dalvik fit in the brave new Oracle Java landscape?
In the brave new world of open source, multiple related platforms are a given. There are many Unix-like operating systems and many Linux variants, optimized for many uses. I see Dalvik as a VM designed with a very different set of design goals and constraints from HotSpot or JRockit.
InfoQ: Following up on that: how do you see Java ME evolving? Being outright replaced? Could Sun "bless" Android as the next-gen Java ME? How can Java ME compete in an Android/iPhone world?
I don't think it's appropriate for me to speculate on this one, though it is worth pointing out that there's certainly a place for "feature phones" (as opposed to "smart phones") in the developing world, and Java ME was designed with feature phones in mind.
InfoQ: At least one, recent index (Tiobe's list) has shown a decline in the use of Java.
It showed a slight decrease in Java use and a corresponding increase in C use. I'm not sure if this is real or a statistical anomaly, but it is amusing to see a 35-year old "universal assembly language" at the top of Tiobe's list. I confess to having a soft spot in my heart for C.
InfoQ: This is probably provable (one way or another), but do you suspect that the JVM's use has decreased over all, or that Java proper has decreased while Ruby/Scala /Jython /Groovy have taken up the slack?
Actually none of these languages make Tiobe's top 20. That doesn't mean they aren't important or valuable; they are. But they aren't mainstream, yet. That said, I'm absolutely thrilled by the amount of language research and design going on these days. There are plenty of good ideas out there, and it's marvelous that people are exploring them.
InfoQ: Do you think Java's on the decline, or that we should be concerned?
I think it's fair to say that Java's had a hard couple of years. But I do not think the platform or the language are in decline. I think there is some danger of a decline, but I'm counting on Oracle and the Java community to prevent it. Yes, I do believe it's cause for concern. I believe a strong Java is good for the programming public: corporations, higher education, K-12, the open source community, you name it.
InfoQ: What, in your opinion, could hope to replace it (that's not also on the JVM)?
With the exception of CLR which is in-practice a Windows-only platform, there's no real alternative to the JVM on the horizon. In fact, there's no real alternative to the Java programming language either. There are plenty of other great programming languages, but none with the same "design center." A language is a tool, and we should use the right tool for the job. One size does not fit all.
InfoQ: Is there a business case to be made for licensing the JRE?
Perhaps some esoteric variants. But I believe it's in Oracle's interests, just as it was in Sun's, to keep the JRE ubiquitous.
InfoQ: Following up on the last one, a bit, but also as a standalone point: how do you feel about the proposed reconciliation of the JRockit JVM and the Sun JVM and various other VM technologies?
In principle I believe it's a good thing to take the best parts of the various JVMs and combine them into something even better. But remember that Sun never even succeeded in combining the client and server variants of HotSpot. Combining multiple systems is where angels fear to tread. It's sometimes doable, but never easy. Failed efforts can be very costly.
InfoQ: Anything else you might add? What do you feel needs to be said?
I just want to remind people that many recent Java success stories are getting lost in all the gloom and doom. Among them are Google Collections, Guice, the JVM languages you referred to earlier, and Android. With swift, decisive action on Oracle's part, and cooperation from the broader Java community, I see a bright future ahead for the Java platform.

How to approach things
With patience! This is the only time I can go so directly (when approaching the approach problem).
Saying 'I've been thinking, maybe to do that...what do you think?'. It is like walking little known icy waters, you have to advance slowly and bit by bit, look for sustainable surfaces.
You will never know the consequences when you go fast and straight, even though you imagined all the possibilities, there is the unexpected. Go really slow, do not draw straight conclusions, do this only much later.
And plus, first comes the denial of what you ought to say/do. This is, so to say, the virgin thick snow on the ice. This makes even hard to advance.

Underground (?)
What some years ago (around 10) I really enjoyed was the underground metal music. Nineties and early 2000 was the most genuine period as a music-listener life. From an authentic feeling of true grimness while listening to Darkthrone and many others more, from the strong fist of the US death metal to the deeply emotional of the doom-gothic era of Anathema, everything was a genuine joy. I had the feeling to be one of a kind, listening to that "noise" almost everybody near me called it so.
Now today, what? We have a My Dying Bride playing on the center of my city's Plaza in the middle of the day! Not to mention also Hypocrisy's Peter played in the front of a multicoloured people also in the middle of the day, and Peter was anything but "friendly" within his satanic music. Ok people change, but I am afraid also we lost a genuine feeling of happiness while listening to something underground, that underground music a long time ago. Looking at aforementioned bands, I could mention the Penetralia album of Hypocrisy, Deicide - Legion, Cannibal Corpse - Butchered, Napalm Death - Utopia, Anathema - Serenades, My Dying Bride - Turn Loose, Sepultura - Bestial, and more with which I would make a list someday.
And contemplating to this, I can see the todays press and artists how much changed: magazines struggles to have something interesting, to tear interestingness out where there is none, bands are up to for money (thus more and more live events - while the CD sales are really down - live with a kind of music I thought then that it should be listened and enjoyed more privately). This context gave also a creative (or a must) impulse for artists, some are really trying things that were not even thinkable, to incorporate different "things". The ones that were aware of the possibility (I would say more a necessity for to be successful) created indeed something interesting and they got a degree of recognition (folk oriented, ambient, even oriental black metal).
I remember a discussion with the Kogaionon magazine guy some time ago and predicted the actual scene image, the result (maybe I had actioned like a catalysis) the magazine really turned into a dark music events organizer (CMI like bands) and the turn Negura Bunget took was again an accurate prediction.
Speaking of Negura Bunget, the Om, although an universal word originating from the beginning of mankind, it has an Eastern root, ok we should look for essentials but BM was about something else, some seemed lost focus, or some are using the Black Metal word just that it is cool. And this is far away from what Black Metal is. This is how messed the things are. This really means there is nothing to believe in, even the artists seemed so convinced in the past, they are turning their art upside down.
Well, my current underground path shifted, and happened once I developed the ABBILDUNG project. Today the underground for me are things free from any form and with or without content, experimentation, improvisation, direct soul and mind output, like the netlabels, the "little" guys doing home music on CDr, the demos I receive frequently for releasing on Essentia Mundi. I invite you to discover this new underground music thorough my websites.

Nu inteleg de ce trebuie sa te ascunzi? Ca artist de ce trebuie sa fi misterios? De ce nu poti sa te exprimi asa cum esti in totalitate. Arta e mai degraba o extensie a ta, nu vrei tu sa fi intr-un fel ci pur si simplu esti, daca e sa vorbim cinstit. Poate arta este si ceea ce tu nu intelegi si nu poti explica in cuvinte si atunci incerci din rasputeri sa o spui totusi.
Este doar o chestiune de imagine si in mare este vorba de business. Imi angajez graficieni sa imi faca website (cel mai ciudat website cu putinta), imi angajez colaboratori sa imi faca muzica, imi angajez impresari si imi masterizez la cel mai tare studio produsul final. Ce e asta? Mai este acest lant ceea ce ai vrut sa spui? Actul artei esti tu cu toata trairea ta.
Cu proiectul meu am incercat sa trec de partea cealalta, de la concept, artwork la sunetul final pot spune ca totul imi apartine.
Mai este de reflectat la asta...

exista particule cu constiinta proprie?
Particles are always in interaction with each others. The concept of a single isolated particle does not really exist in quantum physics. So if particles have consciouness, we do not know, they will certainly share it all the time.
1.Are there respectable scientists (not only biologists) that do not believe in the Evolution Theory? Macro evolution specifically - organisms do not evolve from a specie to another.
2.Are there a sustainable theories that explain the Cambrian explosion?
As you certainly know, all of the today's complex life form appeared then, in a relatively very short period of time, which is very odd regarding the usual evolution.
3.What do you think about the quantum mind theories? Do you believe there is a connection between conscience, spirit/soul and maybe quantum physics? The idea that our thoughts may come from within the limits of the uncertainty principle is fascinating; in this context not event with the understanding of the entire Universe we won't be able to know how thoughts came.
Thanks for visiting Romania,
A student
În limba română:
1.Există oameni de ştiinţă respectabili (no doar biologi) care nu cred în teoria evoluţiei? Mai exact a macroevoluţiei – organismele nu evoluează dintr-o specia într-alta.
2.Există teorii sustenabile care explică explozia din Cambrian?
După cum prea bine ştiţi, toată viaţa complexă a apărut atunci, într-o perioadă relativ scurtă de timp; ceea ce este foarte bizar, având în vedere evoluţia obişnuită.
3. Ce părere aveţi despre teoriile minţii cuantice? Credeţi că există vreo legătură între conştiinţă, suflte şi poate fizica cuantică? Ideea că gândurile vin din limitele principiul de nedeterminare este fascinantă; în acest context nici chiar dacă înţelegem tot Universul, nu vom putea şti de unde vin gândurile.
Vă mulţumesc pentru că vizitaţi România.
In physics we believe, and we know, that from the big-bang, the world went through a very big evolution. First it was mostly energy, then the world cooled off, matter, galaxies and planet appear. So in parallel, I would belive that humankind is not different and also went through evolution.
On the other hand the world has been submitted to great catastrophies, like the one in the Cambrian, where a comet hit the earth. This single cut in normal evlolution made a big changes, dinosaures disappeared and small animals living on nuts and not plants could start their own evolution.
Il salut pe dl. Vincent Keisen Vuillemin si as dori sa-i pun doua intrebari:
1) presupunand ca bosonul Higgs nu va fi observat in timpul experimentelor efectuate in cadrul LHC, atunci Modelul Standard din fizica particulelor elementare mai poate fi viabil, considerand ca nici gravitonul nu a fost inca descoperit?
2) presupunand ca bosonul Higgs va fi totusi observat in timpul experimentelor efectuate in cadrul LHC, acest fapt ar putea aduce descoperiri revolutionare in ceea ce priveste noi posibilitati de propulsie sau generare a energiei? Multumesc!
If the Higgs particle exists according to the standard modeel of particle physics, then LHC will discover it. The model will then be complete. The main question would then be: is there anything else? Are there other generations of elementary particles in our world? If yes a new domain will be open, if not particle physics will end up in a very big desert, as any new generation will be produced at masses far beyong what we can produce in energy.
In both cases that will be a revolution, either new domain of research or our understanding would be correct and that would be it.
So we have to wait for the results of the LHC experiments in the next years.
Au fost de-a lungul timpului tot felul de abordari care incercau sa apropie religia si stiinta, de la Teilhard de Chardin la Fritjof Capra. Dar intotdeauna, dupa mai multi ani, aceste pozitii reconciliante s-au dovedit a fi idei fanteziste si pana lurma idei daunatoare. Ele au fost, cred eu, daunatoare pentru ca multi oameni s-au lasat sedusi de ele abandonand abordarea stiintifica.
Intrebari:
1. Recunosteti in Capra un inaintas al dvs?
2. Cum vedeti viitorul relatiei Zen/fizica?
Certainly Capra was the first scientist who started the reflexion about modern science and spirituality. He is certainly a forerunner in these reflexions.
For very long science and spirituality were two separate domains. More and more I believe that a profound reflexion will continue in reunifying science and spirituality, even science and religion. That is probably also what most of people would like to possess in their life, knowledge, meaning objective knowledge provided by science but also inner spirituality in their life. So they will be able to unify these two directions in themselves.
Desi este greu sa adresezi o intrebare fara sa pari mult prea naiv, in calitate de profan, in fata unui om ce astazi participa la cel mai mare experiment al omenirii , imi fac totusi curajul de a intreba cum vede Domnul Vincent Keisen Vuillemin, director la CERN si maestru Zen relatia dintre religie si stiinta, dintre creationism si evolutionism, dintre materie si spirit? Avem macar un singur motiv sa credem ca Universul implica Divinitatea, ca omul ca parte a Universului concentreaza nu doar materie ci si spirit sau ca spiritul are sanse pentru eternitate? Sau toate astea sunt creatii ale mintii?! Sunt gaurile negre si altceva decat par a fi? Multumesc!
Everyone is free to believe that the universe was created by a divinity. There no proff what's ever of it, this is the reason why it is part of the domain of the belief. In physics we know very precisely how the universe developped itself from the big-bang. Now where does it come from and why ? We do not belive that any kind of ideal divinity did anything. Probably fravitational waves spread avor a pre-universe, and not observable, gather together and created an accumulating point of creation, pulling in the entise availbel energy of these waves. This is an incredible energy, and it exploded. As mass and energy are the same this energy transformed itself in matter, more and more as the universe was cooling itself off.
Zen is not a belief, religions have belief. So in zen eithet we do not believe to any magic creation by any god.
I understand that your scientific background grants you the authority to talk about Physics. As for your Zen Master degree, I'm not sure what that is supposed to entitle you to confidently talk about.
The discussion is apparently not only about "evolution" and "matter" but also about "creationism" and "spirit". Are you gonna talk about "creationism" and "spirit" from a scientific perspective, from a Zen perspective, or you'll mix your scientific knowledge with your private metaphysical commitments?
When you talk about creationism and spirit could you please specify whether it is a scientific position or a private (Zen) opinion?
Is there an explanatory necessity for the metaphysical-religious discourse in a scientific paradigm or a marginal speculative possibility?
Thank you!
Zen is not a religion. It is a practice of life. It does not deal really with these intellectual concepts, as interesting as they could be, but deals with our life, what to do, how to do it, how to behave? It is a very practical discipline. Spirit, or mind, in zen is not separated from the body, so we do not talk really about spirit but about body-mind.
credeti ca religia si stiinta se pot impaca, sau chiar completa? considerati ca filosofia buddhista este mai aproape de esenta nevoii de credinta dacat crestinismul?
Buddhist monks have a great faith. In terms of belief, they believe in themselves. So zen is not a religion.
It is a discipline to understand deeply oneself, who we are, what is our mind, so it develops a knowledge of our self.
Scientific approach is also developing the knowledge that we have about our world. But we are not separated from our world. So knowledge of oneself and knowledge of our universe go together. In the future more and more these two approaches will become closer and closer.
So the zen way is better to approach also science as religions as it does not have dogmas.
ca practicant de zen, sunteti de acord cu ideea ca daca omul si-ar putea controla emotiile , n-ar mai exista razboaie pe pamant?
Sitting quietly in breathing slowly, observing his own breathing, calming the thoughts, is a practice which helps everyone in understanding better oneself. So in understanding also his own emotions.
This is a practice of peace, and allow the people to know, recognize and control their emotions. Then yes, this is a practice which will help peace in the world.
1. It is said that the spirit needs nothing (material). Why are you looking both direction (scientific research and spiritual evolution), are you still looking for "the answer" or you found a link between the two?
2. How do you see the future: full of technology and robots or a very natural and spiritual one?
For centuries, people believed that the body and the mind were separated. It created a lot of problems. In zen we unify the body and mind, and do not consider that any kind of spirit could be around just by itself. As exemple, if you switch off your television set, you do not have any image anymore. Both go together. Same with brain and mind, or consciousness, or spirit.
I just cannot imagine the future with robots. People need to get close to their own self, otherwise they will be totally lost. So I frmly believe that if the world wants to survive, it will have to be more and more spiritual. This is what I wish, anyway.
Thank you for sharing some of your knowledge here!
I have two questions - one for the Physicist, the other for the Zen Master:
1. Is there any evidence that elementary particles are subject of self-organization processes, similar to what happens in biological swarms?
2. All the species evolve by adapting to a dynamic environment. Humans are evolving by adapting to an artificial, man-made, environment. Isn't that dangerous?
Particles are always interacting with each other, under the rules of quantum physics. There is no evidence that particles would have their own will. Biological beings have a much more complicated organisation, and for some of them consciousness has developped. There is no evidence that the same would valid for elementary particles.
Humans and environment are fully linked. In each of these questions, the answer is more on the side to find a third dimension where any contradiction, apparent, is suppressed. So humans I believe go through evolution due to many factors, themselves and envirenmental. Dangerous ? we will see then.
Omul este Creatie ! Lumina este Lumina Creata sau NeCreata! V-ati pus vreodata intrebarea : cine suntem, care este forma de energie care leaga si ajuta la interactiunea tuturor formelor de energie ?"
ati participat vreodata la o Sfanta Liturghie a Bisericii Crestin Ortodoxe ??
Sa nu uitam ca mari savanti ai secolului XX au "sfarsit" prin a recunoaste ca deasupra tuturor mai "exista ceva"!!!
Doamne ajuta !
Universe is made of mass or energy. It is everywhere.
De ce oare oamenii totusi isi accepta moartea, asa usor? cumva este o greseala de gandire comuna? vad milioane de oameni suparati pe fenomenul globalizarii, cer protectia ursilor polari sau a focilor in Canada mult mai insistent decat cercetare medicala pentru a supravietui mai mult. Daca cineva isi exprima dorinta de a trai 200 de ani este repede privit urat.
Multumesc!
Everything which starts is bound to have an end. So everything which is submitted to birth will one day dies. It is an obvious fact that everyone has got to accept. The fact that we will die is actually the only thruth that we have really.
In your opinion, which is the connection between consciousness, energy and matter?
Thank you
In opinia dumneavoastra, care este conexiunea dintre constiinta, energie si materie?
Concsiousness and energy / matter should not be separated. Brain and consciousness go together.
1. cum ati ajuns sa practicati zen?
2. ati incercat si alte cai spirituale?
3. exista cercetari care au pus in evidenta existenta ki-ului?
When I was young I was going to the protestant church. I wanted to find a spiritual way that I can really practice with my body and my mind. Going on Sundays to church was not suffisant. So I read books about zen and I started to look in Geneva if there were a zen dojo. I found it and continued to practice for more than 25 years.
There is a beautiful zen dojo in Bucharest, you should go and try zazen with the other practicants and monks.
Ki is energy. Now the universe is expanding, we believe that it is due to dark energy, the energy contained in vacuity. So yes, there is evidence. Also if you live it means that you have ki !!
As avea 4 intrebari :
1) daca este de acord cu ipoteza ca Universul e o holograma si ca în aceasta perspectiva suntem toti niste Dumnezei , cf cartii lui Michael Talbot , Holographic Universe :
http://www.amazon.fr/Holographic-Universe-Michael-Talbot/dp/0060922583/ref=sr_1_2?ie=UTF8&s=english-books&qid=1270744968&sr=1-2
2) daca crede în reâncarnare si ce ne-ar recomanda sa citim ca sa întelegem mai multe despre o eventuala lume a spiritelor ( locatie, dinamica, organizare, etc) (asta în calitate de maestru Zen) .
3) daca raspunsul la întrebarea 2 e pozitiv, daca crede ca exista mai multe dimensiuni decât cele 4 pe care le cunoastem noi azi ( 3 + timpul) si când anume o sa progresam în cunoasterea lor .
4) daca e posibil ca experimentul CERN sa duca la descoperirea unor noi forme de energie utilizabile în viitor ( posibil "furate" de la extraterestrii ???)
Multumesc.
Zen is a practice of life, it is not a belief in some kind of reincarnation. Questions are: how to live, what to do? Personnaly I do not believe in reincarnation, although the atoms which form our body will not disapear.
CERN, if it exists, may discover new forms of particles. Energy is energy.
Voi formula o serie de intrebari legate de viata noastra de zi cu zi, la care va voi ruga daca aveti timp sa imi raspundeti cu o opinie personala sau daca este cazul cu un fapt demonstrat.
1.exista universuri paralele?
2.de ce uneori apar distorsiuni de timp(fizic sau mental)
3.se poate modifica orbita(locatia) pamantului cu tehnica actuala?
4.toate particulele sunt la fel in multiuniversuri(daca exista) sau au opusul lor ?
5.cum comentati experimentul philadelphia?
6.cercetarile echipei sunt bazate si pe descoperirile Hendrik B. G. Casimir, Otto Stern?
7.In caz de esec a unei etape ale proiectului ce sistem de avertizare aveti fata de populatia globului?
8.de ce incercati sa aflati originea unui univers cand pot exista infinit? o sa construiti un CERN pe toate din acestea?
9.o gaura neagra nu poate fi o poarta catre alt univers deoarece intre datele (BUS DATA) existente nu exista o relatie de feedback care conform cuantumului efect-cauza este supranecesar.Deci pentru ce interes pentru black holes?)poate si financiar...)
10.cum scapati de energia degajata in sistem (se stie ca nici o tehnologie actuala nu poate inmagazina sau consuma o energie echivalenta din testul final al acceleratorului cand atinge punctul critic)
There could be other universe, but they would be fully separated form ours because in betwen them there would be no space and no time.
We cannot change the orbit of such a big planet.
For religion, our Planet is a VERY special place. For Science it is one of the billions of planets revolving around a star in a galaxy. Creationism says Earth
is 6000 years old than was the Universe created.
Science has established that there are distances
of billions of light years to the far galaxies. This seems
to contradict the Young Earth concept. Logically there are two possibilities:
a) the velocity of light is very low, snail like;
b) Young Earth concept is a fairy tale for adults
What do you think, Master?
Thank you!
The velocity of light is a generic constant of our universe, like the mass of the electron. If the sped of light would be different, our universe would be totally different.
I think it is a nice tale but for children.
Holographic principle would be a big help to researchers trying to unite quantum mechanics and Einstein's theory of gravity? What do you think about GEO600 experiment?
Actually nobody knows how to put together Einstein general relativity and quantum physics. This is a real problem in sciences.

Exista particule indivizibile sau doar diverse forme de concentrare a energiei ?
The lectron is believed to be a point-like particle without any inner structure. Masses can actually by considered as a concentration, very local, of energy. In that sense mass is energy at rest.
In contextul cautarii particulelor responsabile pentru conceptul de masa care ar fi cauzele conceptului de timp si spatiu?
Particles, mass, energy is quantified. Space-time is continuous, we do not know how to put these together.
Biblia afirma Dumnezeu l-a creat pe om dupa chipul si asemanarea lui .
Albert Einstein ne da ecuatia E = mc2 (patrat) si face afirmatia : Putini vor intelege semnificatiile acestei ecuatii.
Cum vedeti dumneavoatra cele doua afirmatii ?
Va multumesc mult
The Einstein equation means that energy and mass are the same. Mass as concentrated energy is linked to it by this equation.
I dont believe in God but my faith in myself is real.
Do you practice Transcendental Meditation?
If not, what kind of meditation do you practice?
What's your opinion about the Unified field theory?
I practice zazen, the sitting silent zen meditation.
Unified Field Theory is certainly a desire to unify the forces in universe. It is by far complete.
Between the atom's particles there are huge empty spaces if we look at their own scale.Particles are coming from an empty space giving to us the illusion of shapes through they came and disappear with the same speed.
Question: From where they came,who send them and where they go ?
Particles are coming from vacuity. This vacuity is full of interacting sub-jacent fields. If a proto-particle connects to these fields, it will pull out energy from them. As mas and energy are the same, when it has pulled out enough energy, it will appear as a real particle in our world. They can also disapear when they annihilate each other, and the corresponding energy will go back to these fiels, namely to vacuity.
It is a physical phenomenon, there is nobody really doing it.
I will argue here against some of the previous contributors, based just on the credentials provided by hotnews, and say that Dr. Vuillemin is much more like a character from that famous book about spices, worms, churches and extreme science.
(Dune, F. Herbert).
Some questions, then:
1) Why zen and not scientology ? Why should we believe Dr. Vuillemin and not Tom Cruise ?
2) Besides the comforting role for the masses (and hence the political implications for mass control),
do we, as individuals, really need any kind of religion after all ? In other words, can we rationally find God ? (Wittgenstein concludes that questions like the last one above are nonsense, just linguistic combinations)
3) Rephrasing 2): science seems to prove more and more that most of our features, if not all (behavior, appearance, biological constitution and so on) are controlled, determined by genes. What's left for the Spirit ? Quantum mechanics, perhaps ? And then Matter is Spirit and so on, the eternal vicious circle ?
Scientology is just a damned fake. You do have to believe, you should believe in yourself, and certainly not in Tom Cruise.
If the people want to believe in God, they are free to do it if it is good for them. Personnally I dont, and I dont need it.
Genes, living bodies should not be separated from mind. A human being is a body-mind complex, no need to separate them, there is no mind without body.
Reincarnarea este o chestiune doar de credinta sau are si argumente? Daca exista argumente in sprijinul ideii de reincarnare, v-as ruga sa ne vorbiti despre acestea!
Reincarnation is just an hypothesis. There is no real evidence.
As a scientist eager to learn the results of the CERN experiments, does it help to be Zen in the waiting process?
Yes, results from LHC are expected, it will take some time until enough data have been collected. Patience then. Sure in zen you learn to be patient, sitting still for hours !
Recent, Romania a semnat acordul privind statutul de candidat pentru aderarea la CERN. Ati lucrat vreodata cu cercetatori romani? Ce avantaje ar aduce Romaniei aderarea la CERN?
Yes, I have the great pleasure to work with Romanian scientists, a woman mechanical engineer, and a radiation chemist specialized in the study of irradiated materials. They are excellent scientists.
Romania has been recently admitted unanimously as a candidate to become later a full memeber of CERN This is a great advantage for Romania as well as for CERN. Romanian scientist have been collaborating from the 90's with CERN and have brought essential contributions in the construction of the LHC experiments.
As candidate, Romania will be able to send its young scientists to CERN as Fellows, doctorants and scientific associates. All Romanian scientists will be able to use all facilities at CERN. In addtion the Romanian Industries will be able to apply to the CERN offers for construction in all domains.
In 5 years, if Romania and CERN agree, and if the CERN conditions are met for Romania, it can then become a full member of this international scientific community. Already Romanian professors have come for training and information to CERN. So all these exchanges profiting the Romanian students and professors will also increse.
This is an excellent news for both, Romania and CERN.
Trying to re-create de moment Universe was born is already a daring thing and proves that science is advancing fast. Do You think that in some years time will scientist try a huge experiment concerning time travel?
Time travel is impossible. Time is just what separates events, one cannot recreate events of the past.
The LHC experiment was plagued by various technical problems and some people lost confidence in the experiment. IF the LHC will unfortunately be hit in the next years by many technical problemes how many years are the managers of LHC determined to continue the experiment?
After this incident, CERN took a great care in not only curying it but also in increasing safety in controls of the magnets, and other means so if magnets would quench, which is a normal phenomenon, no damage will occur. We made very big progresses so such dramatic event should not happen again.
Also we are prudent in increasing slowly the intensity of the machine.
At the moment we have started and it all goes well. It will take some years before this very complicated accelerator complex reaches its nominal luminosity and energy. The experiments will certainly also continue searching for new phenomena, Higss, others. For such discoveries a big amount of data needs to be collected, this is what we hope to do during 2010 and 2011. Then a shutdown to upgrade things in order to reach full energy.
