New Paper on Optical Manipulation of Thermal Atoms.

Chaotic dynamics of thermal atoms in labyrinths created by optical lattices.
Rafael Pérez-Pascual, Blas Manuel Rodríguez-Lara and Rocío Jáuregui.
Accepted at the Journal of Physics B: Atomic, Molecular and Optical Physics.

We study the dynamics of non interacting thermal atoms embedded in structured optical lattices with non trivial geometry. The lattice would be generated by two counter propagating modes with parabolic cylindrical symmetry and we concentrate on the quasi conservative red detuned far-off-resonance regime. The system exhibits quasi periodic and chaotic behaviors whose probability can be controlled by varying the intensity of the beams. The spectral density of the trajectories is used as a chaos signature. An analysis of permanency times for chaotic trajectories that visit more than one potential well reveals a distribution with a long tail.

Metropolis by Thea von Harbou

I was introduced to Metropolis back in my undergraduate days; it was Rintaro's Metropolis anime adaptation of the manga with the same name. A few months after this first encounter with the topic, I was lucky enough to be in a screening of Lang's Metropolis, the German silent film based on the original novel. It was with great pleasure that I found the original topic more interesting than the loose Japanese fanzine---I did like the anime.

Yesterday, I just finished reading the novel written by Thea von Harbou which was the source for the screenplay made by her and Fritz Lang, her husband at the time. I got the electronic version through feedbooks a few weeks ago. Truth be told, even after reading the novel, I can barely remember a few scenes from the silent film; but the novel is a swift good read. The writer uses repetition more than I like it but to a good effect.

Metropolis is a science fiction novel that deals with a industrialized futuristic dystopia where the gap between the rich and the poor is so large that the simile used for the labor masses is "food for the machines." The main thesis is that "the heart is the mediator between hand and brain;" promoting a non-violent mediated solution to the clash of the classes.

As expected by the main thesis, there is a good share of love, fidelity, and loyalty stories that help unfolding the main plot.

While I do not agree with the main thesis---reason and common law based on reason are there to give structure to society, not emotions---, as I said before, it is a swift read, with one of those happy endings, Gothic cathedral swashbuckling and redemption of the astray dictator included.

Last weekend movies...

It was a long week; I managed to get my hands on a couple of good movies, one of those a thriller...

  1. The Ghost Writer, ***
    I like the way Roman Polanski tells a story --in particular, thrillers. This film tells the story of an unnamed ghost writer, portrayed by Ewan McGregor, hired to finish the autobiography of a former British Prime Minister. The plot is simple and you can figure it out by the middle of the film, the twist are somewhat expected. The ending, the ending is great!

  2. World's Greatest Dad, ***
    By the title, and Robin Williams playing the lead role, I thought this would be a comedy. On second thought, it might be possible to classify it as a satire, a very noir satire. The film was written and directed by "Bobcat" Goldwaith, yes that "Bobcat." The film deals with fame dreams, lonelyness and family in sort of modern and distorted fable. I really liked the fable feeling of it, simple, straight-forward, moral included.

  3. Year One, *
    Revisit the first couple of thousand years of known written history in a few days. Less than two hours in real time. This is one of those movies where you don't have to think but I really don't like. Allegedly a comedy, I feel it like one of those movies that try to make a point, in this case that reason is the fundamental truth and source of self-knowledge, thus source of inner peace and happiness, make it but fail to make you laugh or keep entertained.
I also managed to see the latest, at the time, episode of Big Bang Theory, fourth season's episode nine, where Raj and Howard manage to get themselves in an awkward situation while Penny's dad begs Leonard not to give up on her daughter. Glee's second season's episode seven was a stunner featuring Gwyneth Paltrow, who happens to be an amazing singer and dancer. Finally, on the second episode of The Walking Dead our Sheriff manages to escape impending death and is closer to find his kid, ex-wife and ex-best-friend-who-is-doing-his-wife.

Is Mexico a failed state?

This week, I was shocked by the story of Dn. Alejo Garza (RIP), a 77 year old man that died defending his ranch from a drug gang that decided to take over his property in Tamaulipas, my home-state.

When I first read the story, I was surprised it didn't happened in Monterrey during one of the drug-gang-blockades that are becoming part of the daily life in the "Sultan of the North." Somehow, I had the impending doom feeling that people in Monterrey would start carrying guns to protect themselves from the gangs stealing cars and trucks to block the city streets, in order to prevent the transit, in and out of town, of the military and federal police during anti-drug operatives.

I have to say that the smallest part of the shock came from the fact that Dn. Alejo (†) managed to kill four gang members and wounded another two; what really freaked me out were the implications of such actions---as the monopoly of violence is, in the early theories of the role and responsibilities of the state, mainly those proposed by Max Weber, the defining characteristic differentiating a sovereign state from a failed one, and Mexico does not sanction a self-defense stance by an armed population---; that is, added to the illegal acts of violence and terrorism committed by the drug lords and associated gangs, now there is an illegal act of violence committed by a civil in self-defense, which has been praised by some sectors of the civil population as an exemplar attitude and stance.

In our modern times, one could argue that the monopoly of violence is not the only important factor to define a sovereign state. There is the economics factor, the provision of services and law, etc. While there's a relative economical stability in Mexico, it is clear that the state has lost the monopoly of violence, alas, thousands of deaths related to the drug war of the last three years testify in favor of this thesis; even sadder, the drug war, allegedly started as an answer to the corruption and infiltration of the government by the organized crime, and the possibility of a civil population taking matters on their own hands instead of denouncing the crimes to the authorities, testifies to a generalized perception of a corrupt law enforcement and judicial system that does not protect nor serves the common citizen. With this in mind is not a surprise to find Mexico in the warning list of the Failed State Index by the Fund for Peace.

Mexico is not yet a failed state but it will take the efforts of the whole country to steer the future out of harms way. Education and transparency by the government, as well as an exemplar citizenship that denounces and follows the law, are key factors for a safe tomorrow that might or might not depend on legalizing drugs. If corruption and privileges without accountability and responsibilities are the goal in the mind of our everyday José, then, sadly but true, we are fucked up as Mexicans.

ERRATA: My good and old friend Salvador pointed out to me that, while it might be hard to argue self-defense in Mexican Courts, the Mexican Constitution sanctions the right to have non-restricted registered weapons at home and, in some special cases, to carry a weapon for self-defense in its Article 10.

Last weekend movies...

These last days I had an even stronger urge for no-brains-needed movies. Such was my luck that I found one that I really liked...

  1. Scott Pilgrim vs. The World, *****
    It has been a long time since I enjoyed a films so much. It is not about the crappy dialogues. It is not about making jokes about the Canadians. It is all about the visual storytelling! There are always so many things happening on screen, the pace is fast and furious, it is a fantastic surrealistic trip!

  2. 2012, **
    I was looking for no-brain-needed movies and I got what I asked for... This apocalyptic story lack a good everything, storytelling, photography, acting, included. And the kid name is Noah. I rest my case. I was used to think of John Cusack as an actor involved in interesting films, but lately this is not the case.

  3. Night at the Museum: Battle of the Smithsonian, *
    The weekend before the one had great no-brain-needed movies, this one just did not figure out. I really had the hope that this sequel will be better than the original, but it is not. But, I will not lie, Octavius had the best line in the movie:"I ride on the back of nature's most fearsome creature! I ride... the squirrel!"

  4. Street Fighter: The Legend of Chun Li, *
    Come on! At least they could have tried to made an effort with Vega's mask.
Finally I managed to get back on track with the tv series I'm following this season, Big Bang Theory is now showing fourth season's episode eight and Glee is showing second season's episode six, both of them are good. While Glee is getting better, but nothing better than the Rocky's Horror Picture Show episode, Big Bang Theory is somehow losing its edge. I added The Walking Dead to my series roster and it is great! Good old fashioned horror; a must see!

The Man by Bram Stoker

Last weekend, I finished reading The Man by Abraham "Bram" Stoker. I downloaded a copy from Project Gutenberg. The quality of the text was excellent; it has happened to me, a few times in the past, that suddenly some undecipherable typos show up on these versions, but this time the few ones that showed up were quite simple to decipher.

“I would rather be an angel than God!” I guess Firmin would classify this as a great first line! The book lives up to the expectation of such an awesome first line. I'll be honest; this is the first Stoker's book, after "Dracula"---which is also public domain and you can download at Project Gutenber; as far as I know, Stoker's grandchildren just published a sequel trying to recover the rights of "Dracula" for the family---, that I read. I might be completely and utterly wrong, but the last part of the book read as a "Pride and Prejudice" without Zombies nor too much Prejudice, just enough.

The novel uses a romantic drama to deal with personal values, both classical and modern at Stoker's times, embodied in a series of characters, mainly two young people, a male and female, and a cohort of secondary characters appearing here and there, in a setting that has a late-XIX century feeling.

It is a fluent, entertaining and good read. Stoker's narrative takes you to places in England, shows you the magnificent view preparing the setting for well defined characters that you get to know more deeply as the pages turn. It is a long read, around three-scores chapters, but it doesn't feel so.

In summary, I highly recommend this book; and it's for free.

Tunning your Latex in a Linux box

Whenever I install Latex, in particular the texmf installation that comes with Ubuntu, I always end up missing some style, class and bibliography files. In order to fix this, I always do the following:

  1. Copy the files' directories that I'm missing to /usr/share/texmf/tex/latex/ for styles (*.sty) and classes (*.cls); and to /usr/sare/texmf/bibtex/bst/ for bibliographic styles (*.bbt, *.bst)
  2. Make sure the directories are accessible for all users: chmod 755 -r /usr/share/texmf/tex/latex/ /usr/sare/texmf/bibtex/bst/
  3. Reload texmf with: sudo texhash
This always works for me whenever I do a fresh install and have to install the proprietary classes and styles from OSA, IOP and APS.

Revtex 4.1 needs particular attention in Ubuntu, as the natbib package in the current distro is the old natbib. In order to make available the new natbib I do the following:

  1. Download natbib.ins and natbib.dtx and all the .bst files from http://tug.ctan.org/tex-archive/macros/latex/contrib/natbib/
  2. Compile the instaler: latex natbib.ins
  3. Copy the result to a natbib folder in /usr/share/texmf/tex/latex/ for styles (*.sty) and /usr/sare/texmf/bibtex/bst/ for bibliographic styles (*.bbt, *.bst)
  4. Make sure the directories are accessible for all users.
  5. Reload texmf with: sudo texhash

Now, everything should be ready to use the nice features of natbib in Revtex4-1 like \cite{SomeCite, *SomeOtherCite} in order to put SomeCite and SomeOtherCite in the same reference number without having to do it by hand.

I hope you find this helpful.

Last weekend movies...

I have been out on vacations for some good six weeks. While I was focused on sitting at home enjoying time with my family, I also tried traveling a little bit to visit friends. Anyway, I managed to watch some films...

  1. Despicable me, ****
    I watched this animation on the plane back to work. It is a funny story of anti-heroes, which I really like, most of the time, family and somehow that evasive thing that is redemption without repentance.

  2. Los Perdedores, ***
    These is a film based on a tytle by DC's Vertigo comics, The Losers. This film tells a renewed story of five fucked-up-by-a-rogue-CIA-agent special-ops agents trying to find their way back home. I knew nothing about any of the actors before watching this movie. It's a good no-brainer to cool off and kill the day. It is also a film of anti-heroes and , somehow, redemption without repentance.

  3. The Expendables, ***
    I like movies where you do not have to think at all. This is one of those. You just sit down and start wondering how the body count will end. It was awesome to see all the action heroes of my childhood together in a film. I have heard there'll be a second part and I hope they can get some of the ones that were missing; e.g. van Dame, Seagal, and Chan.

  4. Ip Man: The legend is born, **
  5. Ip Man, ***
  6. Ip Man 2, **
    When I was living in Taiwan, These three films were all over the movie theaters. at last, I managed to watch them on the plane back to work. They are Taiwanese productions, I think, that give a fantasious semi-biographical portrait of Grand Master Ip Man, the man behind the worldwide spreading of wing chun martial art and teacher of Bruce Lee. I liked the films; they are good martial art films. I have to tell that I have admired wing chung kung fu for the last 10 years and would like to learn it.

  7. The Wolfman, **
    First of all, Anthony Hopkins and Benicio del Toro are the reason for the stars. The realization of this story on lycanthropy is somewhat dull and boring. I was hoping for a dramatic Victorian tale, full of the subtle horrors characteristic of Victorian drama, but found a rather really bad composed love drama.

  8. Jonah Hex, *
    Based on the DC comics western comic sharing the same title, Jonah Hex. This film tells a renewed beginning for DC's western cowboy anti-hero. While I will not complain about the film, John Malkovich plays the evil mastermind role and über-hottie Megan Fox plays the über-hottie anti-hero's love, it is better to save it for one of those really boring rainy days when all the good books and movies at home have been read and watched.
And those were the films we watched these last six weeks of home, enchiladas and carne asada. Have a great weekend and an awesome week!

One year.

One year is 1/60 th. of an average life span in my beautiful Mexico. One might be inclined to think that life remains almost unchanged over such a short period of time. Nevertheless, life has changed a lot over the last year. My hometown has become a ghostly shadow of itself.

A year ago, it was a common occurrence to go out dinning with friends; chasing the food with a few shots and a walk, beer in hand, on the sandy beaches of our Miramar. Sundays were started with breakfast at home and noon mass was followed by a short drive out of town to enjoy the river or lagoon bank, where the afternoon was spent at some fresh sea food restaurant watching the kids play, the boats sail and the beer bottles dry.

Today, I readily cower at home short before the sunset with an --perhaps morbid-- eye on the twitter updates in order to know where the daily shootout is happening. Sundays have become the melancholic memory of a short lasting past that found death at the hands of a violent present. I guess the kids still play, the boats still sail and the beer bottles dry, somewhere far south from the Mexican--USA border.

In one year, the political campaigns of those guys running for the Mexican presidency will be all over the news and, most probably, there will be nothing to say about us, the North. Even today, there's nothing to say about us. News are spread by twitter, emails, and common gossiping at non-public places.

Years come and go. One by one. Each one of them makes the difference for one and many. This year of mine is getting to an end. I hope the next one is filled with friends, dinners, shots, walks, kids playing, boats sailing and beer bottles drying.

God bless us all, but first of them all those who are fighting so they can find Him on their hearts and stop this useless war. God bless and touch them this and every year.

Last weekend movies...

Last weekend I took a long plane trip, so I ended up watching some movies. They were all remakes and follow ups. Nothing really great...

  1. The Karate Kid, **
    A remake of the 1984's film: The Karate Kid. Which, by the way, is based on a short story called "現代 ゲーム" (Sometimes the Heart of a Turtle) written by Kenzaburo Oe, a Japanese winner of the 1994 Nobel Prize in Literature. His Nobel Lecture is quite interesting. Curiously, Professor Oe was a lecturer at Colegio de México, the top academic institution in Mexico. Anyway, coming back to the film. The good thing: Jackie Chan!

  2. The A-Team, **
    A remake of the 1980's tv-series "The A-Team". Squash, Boom, Bang! I have no more to tell about this. Oh, sort of, the good thing: Liam Neeson.

  3. Predators, *
    Last time I watched a movie about Predators, I went to sleep during the first sequence and woke up during the last sequence. I will tell no more than this: I watched this film because Adrien Brody was in the cast.

More haste, less speed

Daniel, my fellow Mexican and newest addition to the book of friends and acquaintances, uses to joke about my "autistic ways of doing things." I really enjoy his jokes about this topic because they remind me that I am not careful and slow by nature but by experience.

As acting in careless hurries has given me so much trouble in the past, I try my best to follow the rules whenever there are rules; in my personal life, I try to establish and follow routines; in my work life, I try to set paths -you will always find a "To Do" list somewhere on my desk or wall-. Why do I do this? Because, by birth, I tend to do or speak faster than I think.

In Spanish there's a saying, Lyx just brought it to my mind, "No des puntada sin hilo" (Do not stitch with a thread-less needle), which I believe is somewhat equivalent to the "More haste, less speed." Whenever one embarks with haste on any given action, desired results will not be delivered and, most probably, your actions will be in vain.

Today, I find myself in a situation that I could have avoided by following the rules as they are written. Tomorrow, I will find out about the path to follow in order to correct my haste. Anyway, knowledge is the reward of action; I have learned: "More haste, less speed."

Down and Out in the Magic Kingdom by Cory Doctorow

As I needed to recharge batteries, I spent this weekend reading, another free and good short novel by Cory Doctorow, Down and Out in the Magic Kingdom; released under the creative commons copyright license, you can download it for free.

The novel deals with a good many things from philosophy of the self to political manifestos. What really got me is reading about the once hot topic of science fiction: life eternal. It might be that I have not been reading science fiction lately and I have lost my bearings, but it seems that the 20's to 60's fascination with life eternal somehow got diluted in contemporaneous science fiction.

I also liked the way the author presents a political/economical/cultural scenario through the exploration of change at the personal level. In the future, there might be a thousand ways to help us cope with feelings, emotions, change and all those things that take us away from the narrow path of logic and rational actions, but what about living with the lack of them?

Anyway, I imagine that this work can be read in many different ways. I'm waiting to hear about your opinion.

Overclocked by Cory Doctorow

Last week, I bought myself a small android pad; so far, I have used it to read free books. While almost all the jewels of classic literature belong to the public domain, look for example at Project Gutenberg, it is hard to find good and free modern literature. Enter Cory Doctorow.


Overclocked by Cory Doctorow is a collection of five short science-fiction stories published under the creative commons copyright license. In short, you can download, distribute and generate derivative works if you follow the rules. When I started reading, I got the feeling that I would like the book; all the stories carry the name of an already famous science fiction story. After the second page, I realized I have already read the book and, most probably, it is gathering dust in my bookshelf at my mother's house. Nevertheless, I read it again and revisited Doctorow's views on copyright, sentience, netiquette, utopias, dystopias, and, of course, apocalyptic futures.

If you have a few hours to spare, each story is just a few scores of pages, please go to the Overclocked download site and give them a try. You will not regret that well spent leisure time.

The Door into Summer by Robert Anson Heinlin

I have just finished reading "The Door into Summer" by Robert A. Heinlein, one of my favorite science fiction writers. This is a time-travel novel written in 1956. It is set, mainly, in a fictional, at the time, California of 1970 and 2000. It deals with one of the paradox on the flow of time and multiple personae; what if you somehow step out of the time-line for a while, in this case by means of cryogenic sleep, and then, after waking up, manage to go back to the time before you step out, avoid mixing with your former self, step out again and then reintegrate to the time-line before you woke up the first time? I cannot write more about it as I'm already confused.

This novel is quite different from what I have read by Heinlein, that is the Lazarus Long saga, the novels where any of the Rolling Stones appear somehow, Starship Troopers, et cetera. It shows a most grounded engineering side of Heinlein and seems to be written in quite a nonchalant mood. It reads pretty easily and smoothly flows.

I actually recommend it if you have nothing to do on a rainy weekend or a long trip. You can easily finish it in less than 8 hours.

This book is still under copyright law and not part of the public domain. You have to get a copy or an e-copy. Mine cost $290 TWD, which was around $8.50 USD at the time. Those were some nicely spent TWDs.

Hope

And, then, the day came,
when hope, now, didn't fade.
Instead, at first sight of delusion,
it stayed, strong and fueled,
by the same illusion
that destroyed the past

Remember Rome...

Trust me, this really happens, take and give a few words,

-- Thus, we numerically calculate the...
-- Wait, but the Hamiltonian has as constant of motion the excitation number.
-- No, it doesn't.
-- Uhm, really? But if we do this and this, you see the total excitation number and this commutes as far as I remember.

(one month later)

-- Hey, I can show you our calculation that proves it doesn't commute.
-- Oh, really? Please do so, I might be completely wrong about something fundamental(...) Ok, it is not possible to use this map in this way, so let us do it together(...) You see, three lines. I suggest you read Dicke's and Tavis and Cumming's 70s paper on the topic.
-- I don't read old papers. What's the main idea?
-- The main idea is that this and this commutes...

As our guy walked to the next wall to bang his head, he remembers the film "A serious man" from the Coen brothers...

The Korean student: I didn't know the mathematics were to be evaluated.
The Jewish professor: ...
The Korean student: I know about the cat, I understand the cat.

Another step towards the wall, he remembers Rome where something similar to this probably happened a few thousand years ago...

-- You see, the rock found in the side of the...
-- But why do I need to know where to find the rock? We always get our supply from the southern guy. I came here to learn to build arches, not about amalgams.

Thus the knowledge of concrete and underwater construction was lost for a good one and something millennia...

One more step towards the wall and he thinks about the Slovak joke,

Once there was a guy, he wanted to become a writer. He travels to Bratislava and enrolls into the University. So he comes into his first class and the professor assigns classical masterpieces for the students to read through the semester. Suddenly the guy stands up and starts to leave the class quite angry. The professor asks him what is wrong. The guy answers: I came here to become a writer, not a reader!

Well, such is life... Sometimes I wish I could see how's the world doing in 500 years, sometimes, most of the times, almost all the time I am really thankful I'm not able to do that.

Last two weeks movies,

Last two weeks were awesome, Lyx was in Taiwan and we went around visiting three of the cities. There was a lot of walking involved so we had to take some days off, these are the films we watched...

  1. El Estudiante, ****
    This is a Mexican film. The director argues about making films with moral values and somehow he manages to land one or two moral arguments, while the rest are just left dangling in the air. I felt like there was a moment when the stories were three too many and the director has to hastily threat those three.

  2. Up in the air, ****
    Imagine your work is firing people all around the U.S.A. with no place to call home but the airports along the country. This film is based on the novel with the same name and deals with the life of a nomadic self-isolated hermit, and his inner evolution as family and personal life starts to change.

  3. Silent Hill, ****
    I got very excited about this film, being a fan of the arcade games. The movie is not a happy finger shooter fest, as a matter of fact there are only 16 bullets shot through the two hours it takes to watch it. The story behind the origin of Silent Hill is told without any hurry and with care.

  4. A Serious Man, ***
    While we were treated to the usual good storytelling of the Cohen brothers, I'm not a fan of "noir dramedy." The whole stagnant feeling of the film is a great plus, you get to know the main character more deeply thanks to this storytelling trick. A film to watch.

  5. Julie and Julia, ***
    A feminine point of view on the "Crisis of the Thirties." The main character finds solace and meaning cooking and writing a blog about it. Identifying herself with a lady from the past. I was really laughing out loud with the character played by Meryl Streep, her voice and drunk demeanor, while being always sober. You have to watch this film!

  6. Duplicity, ***
    Two ex-secret agents get together to carry the feist of their lives, or so they think. I liked this film because of the confusing storytelling, it is one of those films where I had not one but many theories about what will happen next. I like that!

  7. Whip It, **
    The second film with Drew Barrymore as director. Well, I don't like dramedies, I said it before. I didn't laugh a lot, I didn't think a lot, it was a bland film. Add up that I don't like the "you can do whatever you want to do" plots in general.

  8. Zombieland, **
    A Zombie comedy...

  9. The Prophecy 2, *
    The second film of the saga, Christopher Walken repeats as a rebel Gabriel not willing to share creation with humankind...

  10. The Prophecy 3, *
    At last, the last one. Christopher Walken becomes the redeemed Gabriel and helps saving the day.

  11. Selena, *
    A biopic on the tex-mex singer Selena. Jennifer Lopez plays the role of the Texas singer who became famous in Mexico.

We got one episode from Big Bang Theory. Prof. Dr. Sheldon Cooper gets a faculty prize and the gang has to help him overcome his stage fright, in the end, as with Raj, the solution is booze but, while Raj becomes an international playboy while drunk, Sheldon turns out to be a really lousy drinker. Also I managed to squeeze some time before the vacations to watch...
  1. Andromeda: 4th Season, ***
    The newly created commonwealth starts facing the corruption and inner decay associated to any political organization, or should I say human organization. Now the stories dwell around the backstabbing actions between the many factions inside the commonwealth.

Last week movies,

Last week, it was a crappy heavy loaded week, but I manage to watch at least three films...

  1. Babel, ****
    This film stressed me. Most probably I'm already stressed wanting to push a paper before the end of the month, worrying about the violence in Mexico, and so on. Whatever, this film is just great, it takes you and delivers a great narrative. It builds up, it twist, it uncoils, but fails to give an awesome closure. Nevertheless, a great film. By the way, it was made by a Mexican.

  2. 3:10 to Yuma, ****
    I like westerns. I grew up watching them with my dad, likewise with WWII films. This film is true to the archetypical western film, heroes, villains, repentant anti-hero. It seems like Bale is an expert at playing a serious psychotic role. Crowe plays a nice anti-hero.

  3. Battle in Seattle, **
    The good things about this film: You can learn about being a legal activist. It is not just mindlessly fighting the world elite, but protesting with a greater goal in mind and under the law.

I managed to catch up with the Big Bang Theory, the guys found a ring, a Lord of the Rings' ring, you can imagine what followed. I got myself into...
  1. Andromeda: 3rd Season, ****
    While the attempts to expand the universe and producing possible Deus Ex Machina solutions for latter on have ceased, now the unfolding of inner crew stories and personal plans are not so awesome as the first season was. Nevertheless, this third season managed to keep me interested enough to get the fourth.


Keeping processes running after logging out from a remote server

Sometimes, the workstation at my desk is not enough for running a simulation and simultaneous on-line procrastination; enter the workstation or the cluster of our theoretical optics group.

While a cluster usually has a queue manager, a workstation usually lacks this software. In our case, both cluster and workstation lack a queue manager. Now, a queue manager usually keeps a process running in the remote server no matter what your logged status is. How to do the same without a queue manager? The answer is simple: nohup.

For simplicity's sake, I'm using an SSH connection to a linux machine if I want to leave a process running at the server and then log out I use the command:


nohup command_to_run &

Note that the ampersand symbol has to be issued in order to send the process to the background.

Say, for example, I want to leave the compiled binary file for a fortran program running in the remote server even if I log out:


nohup ./BinFile &

My first encounter with Durif...

Today I was wandering the neighbourhood and found a liquor store. They, the liquor store, trade with whiskeys and, it seems like, red Australian original but Scottish branded wines. While my favourite wines are red syrah, or a mix of it, I got myself a bottle of McManis Family Vineyards's Petite Sirah grape. It was my fist encounter with such a grape so I was a little bit amused about what I will get for my money. I have bought my dinner beforehand and predicted a catastrophe of sorts; it was a sea food dinner and Durif is a tannic. However, it proved I'm a prejudiced ass-hole. It was great! While the mixture of salmon, rice and the Durif wine was not awesome or something I will choose after any other combination, the taste of the Durif wine, somehow a raisin-like flavour, proved awesome for skipping the evening reading the news, watching some tv-series and writing this blog.

So, if you can go for it, try it!

Last week movies,

Last week, I went for one of Lyx choices, as every week, and two of mine. As always, Lyx's choice proved solid gold while mine, well, sucked big time...

  1. The Illusionist, *****
    In the begining I took it for something related to The Prestige, another of Lyx choices. It seems both came to the theatres almost at the same time. While The Prestige story lies heavily in magic and science fiction, The Illusionist plot lies heavily in cunning and illusion. I really enjoyed it. I think the experience was enhanced by the fact that I was expecting some kind of bullshit magic twist like the one in The Prestige, but it never came.

  2. Bridge to Terabithia, *
    Based on the novel with the same title, this Disney movie is just a Disney movie. While well done, there's nothing remarkable. By the way, I have read very good comments about the book.

  3. Blue Crush, *
    The good things about this film: The Hawaiian sea, Michelle Rodriguez, Kate Bosworth, and Sanoe Lake wearing short pants or swimsuits.

While there was a Big Bang Theory episode this week, I didn't manage to watch it, so I will have to catch a rerun. What I manage to get my hands on was...
  1. Andromeda: 2nd Season, ****
    I found the second season of Andromeda a little bit dissapointing; the universe keeps expanding and it seems quite clear how desperate the writters are to set a formidable foe for the dark one in the first season, at least I fealt it that way. I am currently watching the third season so I will keep you informed.

Last week movies,

Last week, I went for the Edward Burns and drinking film combination, again, plus a great fiction film. These are the results...

  1. The Prestige, *****
    In the begining I took it for a drama and thought I've figured out the plot. Then, I was completely abashed. It happens that it is really a science fiction, magic film. A nice story, great twist, great actors and entertainers: Michael Caine, David Bowie, Hugh Jackman.

  2. Looking for Kitty, ****
    This is the Edward Burns' film of the week. It is a story that takes you to those places in New York where the little man stood up to the great developer and didn't sell his piece of land. Those nice old buildings at the foot of skyscrapers. Meanwhile, it takes you into different broken hearts and their ways of coping or not coping. Give this a try.

  3. Swingers, *
    I got the reference to this film from Sideways. The title made me hope for neo-swing, I got lucky as Big Bad Voodoo Daddy plays three songs here. I didn't like the film, truth be told, but it was fun to see Vince Vaughn, John Favreau, Ron Livingston, Alex Desert when they were young and thin. Also, there's Heather Graham. The thing that made me laugh the most was the scene stolen from Reservoir Dogs. That and BBVD made my day.

At last, Big Bang Theory is back on track with the 16th episode of the third season. The guys met Stan Lee, you can imagine that somehow they manage to fumble it all. Also I got my eyes on...
  1. 3rd. Rock from the Sun: 2nd Season, *****
    I found the first season great and wanted more, risking to hate the series in case it didn't live up to the first season. It does, still the episode names revolve around the name Dick and many funny things happen. I'm waiting to get my hands on the third season!


Monday, March 1, 2010

Last week movies,

Last week, I decided to try some films I have heard about every now and then...

  1. The Lost Weekend, *****
    A long time ago, I heard about this film. It is one of those 1945, black and white, great photography and acting, films. The story, a semi-biographical narrative, is based on the 1944 novel of the same title by Charles Jackson. It tells the story of a five day weekend in the life of an alcoholic writer.

  2. She's the One, ****
    This is an Edward Burns film. I like Burns way of writing and directing, somehow you feel the city. Most of his stories have N.Y. and its islands as part of the cast, Burns takes you into the city, gives you a taste of it. Another thing I like about Burns' work is that it explores the feelings of those particular critical moments in men's life. Give this a try.

  3. The Soloist, ****
    Based on the true story of Mr. Ayers, a schizophrenic homeless talented musician in L.A., and Mr. Lopez, a L.A. Times columnist. This film summarizes the book of the same title written by Mr. Lopez. It caught my eye because two good actors are on this film: Robert Downey Jr. and Jamie Foxx; it lived up to my expectations.

  4. Up, ****
    I like Disney's films; the old ones. Truth be told, I enjoyed this film very much. It was a great mixture of hilarious surreal comedy with a lot of sentimental charge. An excellent essay on loyalty, love and living.

Again, there were no episodes for Big Bang Theory or Better off Ted this last week. So, this week I took a swing on:
  1. Andromeda: 1st Season, *****
    I was looking for a good sci-fi television series and I found Andromeda. There was a Galactic Commonwealth and it fell. Fortuitely, one of its top of the line battleships , the Andromeda, maned by just its Captain, Dyllon Hunt, was kept outside of time for 300 hundred years. They have come back into the timeflow and with a ragtag crew of 4, they will try to bring the commonwealth back. I cannot wait to watch the second season!

Profit killed the world

Today, I was working on the phase transition of some Hamiltonian model; listening to random music from YouTube. Suddenly, an unknown version of an old favorite, "Big Yellow Taxi", filled my ears. I kept working on the damned Hamiltonian, then the thought came to my mind...

Profit killed the world

Why this idea came to my mind? I have not a clue. Taking into account that I have no statistical data for the development of Earth's Carrying Capacity and the impact factor of mere consumerism surely is a hard thing to pinpoint, this assertion is pretty unfounded; however, the fact that a human being is just a consumer in modern times, and how it seems that the wellness of The Economy, indeed with capitals, based on consumerism is a worldwide policy, somehow makes me have impending doom feelings and parse the thought as most probably true.

Here's the aforementioned video...



Now, back to the damned Hamiltonian.


Appendix 1: Curiously enough, I found a post in Luis Felipe's blog that gave me the chance to rant about consumerism and responsibility, two of my favorite topics.

This week movies,

Back on a weekly schedule, these are the films I watched last week. As you can see, after a week of not so good films, I decided to go for good old films

  1. The Ninth Gate, ****
    A few weeks ago I commented about how this film from Roman Polanski, based on the Dumas Club by Perez Reverte and featuring Jhonny Depp , shows quite a love for books. It also shows quite a fascination with the occult. I decided to watch it again as it has been almost 10 years since the first time I watched it. It keeps delivering, you should watch it.

  2. Copying Beethoven, ****
    While this is not based on any biography of Beethoven, it is an interesting work of fiction and exploration of human kind. It has an awesome photography and musical score, of course most of it is Beethoven's. Ed Harris acting is just great.

  3. Sideways, ****
    While the best way to study human society is science fiction, romantic comedy is the best format to study the human self. This film deals with middle age, the search for the self, in a road trip centred on wines.

There were no episodes for Big Bang Theory or Better off Ted this last week. So, this week I took a chance to watch:
  1. The Jetsons: 1st Season, *****
    I got my hands in the first 24 episodes from 1962. When George is promoted to the vice-presidency and fired and hired again all in the same episode. When Astro and Rosey were not a common occurrence in the show and Orbitty was not even there yet. Awesome science fiction series.

  2. Third Rock from the Sun: 1st Season, *****
    I watched a few episodes of this series in the past, but never a full season. I am really surprised at the quality of the acting, the satirical exploration of the political landscape of the United States and the ethos of the human being. A must watch.

To my follower Nora,

It was August of 1996 when my wandering started. Back then, it was my choosing not to call home what has been, and will always be, a home for me, my parents' family. While my thought at the time was: I'm leaving to pursuit my studies, God, through time, showed me the wandering was to find my home, my family and myself.

Home, my home, is the wrinkled hands and face of my mother while happily cooking breakfast or praying the rosary. The fat round belly of my old aunt and her trembling Parkinson hands. My best friend struggle with death in the family and economical problems while keeping a good and healthy laugh. My good friend's fight against hypoglycemia while keeping a great faith. My cousin's heart-taking pictures of the world above the clouds. The one whole night of domino with the friends and acquaintances discussing from philosophy to a great set of legs. The short stories, poems and theater plays from my beloved adopted brothers and little wandering cousin. My best friend's struggle with life, love and legacy without surrendering. The smell of smoke and coffee from the adopted family house in Mexico City. The hardships of hunger while traveling with el primo. Those talks about physics and bullshit with my genius German brother. The joy of leisure traveling with my cheerful Slovak brother. Drinking and complaining with my Finnish brother. The sound of waterfalls shared with two wonderful girls. The smiles of the most awesome couple of Slovak mother and daughter. The love of the most wonderful girl ever.

It still sickens me not to know where I will be living and working the next year, or if I will be there for more than 2 years; not to know when is it that I will share time again with all my beautiful cousinettes, by blood or love. But then, I have found my family, my home, my self.

Truth be told, sometimes it is hard to feel secluded, lonely. It has been my choosing. One way or another, I have chosen this path. And, one way or another, there's always been someone sharing it. That's home for me.

There might be no one physically close to you, but if all we need were physical this world would've been a happy perfect place for ages.

My love and respect to my little wandering cousin, the weaver of life stories.

This week movies,

Alas, this last week was a busy week and there are not many films to talk about.


  1. Untraceable, ****
    It is a fair action drama dealing with the subject of "le danse macabre." While the portrait of death in literature and art has usually served an end, at least I want to believe that, this film deals with the fact that in our modern society death has become an attraction, a circus for the masses, the Anonymous.

  2. The Prophecy, *
    There's a world of quotations to chose. There's a universe of fictitious books to quote from. Nevertheless, they choose to quote something that it is not in the Bible. I usually love Christopher Walken acting, not in this film. Vigo Mortenssen plays a great 10 liner.

  3. BloodRayne, *
    Again, a film with a great actor, Ben "Sexy Beast" Kingsley, a sex symbol, Michelle Rodriguez, and the guy we all love, Meat Loaf Aday. Yet the worst vampire film, make it just the worst film, ever. The only good fighting scene involves Ben Kingsley, can you imagine that?

The Big Bang Theory third season, episode 15, is out and guess who is going to the Large Hadron Collider. I'm still waiting for the new episode of Better off Ted, it has been two or three weeks since the last one.

Movies I saw during January

First of all, I sincerely apologize for neglecting the weekly leisure report. The reason behind this is that there is no sun. I know it sounds weird, but I miss my bike rides and that makes me feel without strength or passion to do anything else.

Now, the hard part is to rate the films. It is easier to do so when it is just a few of them and they are fresh in the memory.

  1. There will be blood, ****
    The film is based on the 1927 novel Oil! by the Pullitzer Prize winner Upton Sinclair. I cannot tell you how faithful the film is to the book as I have not read it yet. There will be blood is an exploration of greed. How far can a man go in business, religion and family just to attain a better economical position?


  2. The Wrestler, ****
    Darren Aronofsky has directed two of my favourite movies: Pi and Requiem for a Dream. While The Wrestler does not enter into my favourite films list, it is a good exploration of the ups and downs from fame and prosperity.


  3. 4 luni, 3 saptamani si 2 zile (4 months, 2 weeks and 2 days), ****
    This is a Romanian film, situated in the communist period. It explores the extends of friendship as well as the implications of unwanted pregnancy and anti-abortion laws. I guess this films hits harder for me because it is easy to picture this as a common situation in Mexico.


  4. Knocked up, ****
    What is a relation about? Peter Pan Failure to Launch Male gets Hard Working Female pregnant in the first date after randomly meeting at a bar. The idea of respect for life kicks in. Responsibility enters the picture. This romantic comedy is great in the sense that goes beyond the individual ego perennial in contemporaneous films of the sort.


  5. 500 days of Summer, ****
    Just another romantic comedy iteration of the "Boy Meets Girl" theme? I enjoy this being an exploration of the failed not-happy ending story. Life is not fair or just, but it is not over until you die. Anything can happen in the meantime.


  6. Pride and Glory, ***
    An exploration of the corruption theme in a Police Department. The actors are big names, Voight, Norton, Farrell, but somehow the film fails to deliver. Nevertheless, the moral characters and the the struggle between content and ambition are picturesque.


  7. A fost sau na fost? (Was it or was it not?), ***
    Another Romanian film. I am thinking of it as a comedy, but I am not Romanian. If you go out to manifest your discontent for the Communist Dictatorship after the Dictator leaves, is it, or not, a revolution? Again, I relate to this film because it is so easy to imagine everything happening in Mexico.


  8. The Holiday, ***
    A romantic comedy about two troubled girls with polarized attitudes toward guys. Again a lot of big names, Jude Law, Kate Winslet, Cameron Diaz, JackBlack, and 5 minutes of Edward Burns. It delivers, both a good laugh and the one tear.


  9. Australia, ***
    A romantic drama-slash-adventure film. What really got hold of me is the magical realism used in this film. Magic realism is ever present in Latin America, the writers of Australia manage to exploit the magic of Aus, read with an Australian accent that makes it sound like Oz, at the time "The wizard of Oz" was hitting the theatres and WWII was hitting the country.


  10. The Hangover, ***
    Just watch this film. You are going to laugh yourself to tears. I can not say more, just trying to remind something to write makes me laugh.


  11. Inkheart, ***
    Books, it is all about books. Today, Inkheart seems to me like the first film to talk about books with respect. Polanski's The Ninth Gate with Jhonny Depp, based on Reverte's The Club Dumas, comes to my mind, but I saw it so long ago that I am not sure. In any case, respect thy books.


  12. Enchanted, **
    I like Disney's movies. I love this film and I will watch it again sometime in the future with my kids, if I ever had children.


  13. Smoking Aces, **
    Have you ever seen a Guy Ritchie movie, like: Lock, Stock and Two Smocking Barrels or Snatch or Rocknrolla or even Sherlock Holmes? You can see that this film just screams I want to be a Guy Ritchie movie. Just for your information, it was directed and writen by the same guy who wrote Pride and Glory, Joe Carnahan. By the way, this guy is directing the upcoming A-Team movie. There is a second smoking aces coming this year too.


  14. Ong Back, *
    My first thought was "I must be old, I did not get hype about this martial arts film", then I watched again Kung Fu and Wong Fei Hung just to check and I still get the hype about martial arts films, ergo it is the film that sucks and not my mental age maturing.


This January, I also watched the first season of the following television series


  1. Better Off Ted (Season 1), ***
    The series is focused on Ted, a Research and Development manager in Veridian Dynamics, your friendly all for profit we don't care about you or our employees company, and his moral dilemmas in trying to be a coherent example to his young daughter. You better watch it, you will enjoy it.


  2. Party Down (Season 1), *
    What happens to some of the people that move to L.A. to become rich and famous individuals of the film industry? They end up in the catering industry. I am not into the reality-like theme. I need that detaching "this is fiction" feeling in order to laugh about stupid and hollow people.

The Big Bang Theory third season is back and the episodes 12 - 14 are awesome. So, there is an episode about meta-physics and Leonard gets into trouble for that; in the next the guys got sacked, Sheldon's ensuing paranoia keeps you laughing; finally, do you want to know what happens when a Theoretician has the brilliant idea to go into sleep deprivation? Watch the episode 14.

Casablanca (1942)

Ilsa: Rick, I have to talk to you.
Rick: [Rick is drunk] Uh-huh. I saved my first drink to have with you. Here. [passes her a drink]
Ilsa: No. No, Rick, not tonight.
Rick: *Especially* tonight.
Ilsa: Please... [he pours a drink]
Rick: Why did you have to come to Casablanca? There are other places.
Ilsa: I wouldn't have come if I'd known that you were here. Believe me Rick, it's true I didn't know...
Rick: It's funny about your voice, how it hasn't changed. I can still hear it. "Richard, dear, I'll go with you anyplace. We'll get on a train together and never stop - "
Ilsa: Don't, Rick! I can understand how you feel.
Rick: [scoffs] You understand how I feel. How long was it we had, honey?
Ilsa: [on the verge of tears] I didn't count the days.
Rick: Well, I did. Every one of 'em. Mostly I remember the last one. The wild finish. A guy standing on a station platform in the rain with a comical look in his face because his insides have been kicked out.
Ilsa: Can I tell you a story, Rick?
Rick: Has it got a wild finish?
Ilsa: I don't know the finish yet.
Rick: Well, go on. Tell it - maybe one will come to you as you go along.
Ilsa: It's about a girl who had just come to Paris from her home in Oslo. At the house of some friends, she met a man about whom she'd heard her whole life. A very great and courageous man. He opened up for her a whole beautiful world full of knowledge and thoughts and ideals. Everything she knew or ever became was because of him. And she looked up to him and worshiped him... with a feeling she supposed was love.
Rick: [bitterly] Yes, it's very pretty. I heard a story once - as a matter of fact, I've heard a lot of stories in my time. They went along with the sound of a tinny piano playing in the parlor downstairs. "Mister, I met a man once when I was a kid," it always began. [laughs]
Rick: Well, I guess neither one of our stories is very funny. Tell me, who was it you left me for? Was it Lazlo, or were there others in between or... aren't you the kind that tells?

[Ilsa tearfully and silently leaves. Rick's face falls in his hands sadly, knowing that he's said all the wrong things]
