Are you looking for original stories where the bad gays wins ? Are you tired to see the super-heroes defeating over and over the super-villains ? Or maybe you are simply looking for a new path in your life, far way the kindness and gentleness ... a path where your final goal is the domination of the world or even the entire univers... Then this guide is for you ! I found this compilation of original short stories honouring the evil geniuses.

Eternity is 20 Seconds Long, by Paul Trembling

Kev adjusted his position in the hammock, just enough to look round.

Beyond the shade cast by the trees, the beach was ablaze with sunlight. The glare from the white sand would have been painful if it hadn't been for his sunglasses. Even with them, the flicking pinpoints of light from the sea stabbed sharply into his retina.

There was still ice in the bucket, though, and the drinks were cold.

Along the beach, he could see the girl coming back towards him. The bright orange bikini glowed against her tanned skin. She waved.

He'd promised her a special experience. She didn't know how special it would be. They would have the time of their lives. A very long time. He waved back.

Everything was perfect. Now was the moment.

The device resting on his chest looked like an irregular collection of cylinders, in several different shades of red to purple. The interface unit attached to the side was a crude human intrusion, but necessary. He picked up his PalmPC, linked in to the interface, brought up the programme.

Took a deep breath and hit go.

The rush of alien symbols across the screen was as expected - but surely that configuration was wrong? Alarmed, Kev reached a finger to the abort icon….

DISCONTINUITY

"That's the loop point."

Kev adjusted his position in the hammock, just enough to look round.

"How come he doesn't see us?"

"Different time streams. We weren't there then."

There was still ice in the bucket, though, and the drinks were cold.

Along the beach, he could see the girl coming back towards him. The bright orange bikini glowed against her tanned skin. She waved.

"What about the girl?"

"Outside the field, fortunately. If he'd set it differently, she'd be in there with him."

"How big could it have got?"

"We're not sure. Perhaps the entire planet."

He'd promised her a special experience. She didn't know how special it would be. They would have the time of their lives. A long time. He waved back.

"What was he trying to do?"

"We're not sure. Extend his holiday, perhaps."

Everything was perfect. Now was the moment.

"What is that thing?"

"Temporal field node. Part of a star-drive. Isha'hassat technology."

"How did he get hold of it?"

"That's being looked into. There's quite a black market in alien tech, but this is new. The Isha'hassat are upset about it."

He picked up his PalmPC, linked in to the interface, brought up the programme.

Took a deep breath and hit go.

The rush of alien symbols across the screen was as expected - but surely that configuration was wrong? Alarmed, Kev reached a finger to the abort icon….

DISCONTINUITY

"So what happened?"

"He set up a self-perpetuating temporal loop."

Kev adjusted his position in the hammock, just enough to look round.

"Can we stop it?"

"No. The controls are inside the loop. No one from outside can reach them."

Beyond the shade cast by the trees, the beach was ablaze with sunlight.

"So how long does it last?"

"Twenty seconds. Twenty point two five to be accurate."

The glare from the white sand would have been painful if it hadn't been for his sunglasses. Even with them, the flicking pinpoints of light from the sea stabbed sharply into his retina.

"No – I meant how long will it last? The time-loop-field thing?"

"From his point of view, twenty seconds. From ours – eternity."

There was still ice in the bucket, though, and the drinks were cold.

Along the beach, he could see the girl coming back towards him. The bright orange bikini glowed against her tanned skin. She waved.

"But what happens if the sun explodes – or something like that?"

"If the sun explodes in five billion years, will that affect you?"

He'd promised her a special experience. She didn't know how special it would be. They would have the time of their lives. A long time. He waved back.

"No."

"And it won't affect him either. For the same reason. He's in a different time. Always."

Everything was perfect. Now was the moment.

NRL Plasma Formulary: Hard copies for free

2016-08-30T09:09:00.000+02:00

Maybe you are a plasma scientist and a lover of real books; not those e-books you have stored in your smartphone or laptop in that folder where several megabytes of .pdf files are waiting to be read (and you will probably never read). In that case let me inform you that you can obtain a hard copy of the NRL Plasma Formulary for free. You only need to fill some fields related to your job and position as well as your postal coordinates in the link below :

http://www.nrl.navy.mil/ppd/content/nrl-plasma-formulary

This formulary is one of the most complete I have seen (no matter if you work with cold or hot plasmas) and, in addition, comes in pocket size.

Editing .sce and .sci files on your smartphone

2016-06-05T21:47:00.002+02:00

Ok, you have been programming Scilab functions and scripts all day on your favorite desktop computer. You assume it's all you can do for the day and you decide to leave the desk for a little distraction far away Scilab (an Irish pub and a fresh Belgium beer is a very good solution), and suddenly, in the pub, you find the missing algorithm solution for your functions/scripts. Dam ! How I can edit this functions on my smartphone ??!! Once again the solution is right there on your smartphone and it is unnecessary to waste money and time searching for dedicated applications on the Apple store or on the Play store. You're surely a file manager/browser native application on your smartphone, so the only thing to do is to replace the .sce and .sci extension for .txt and then edit the file with your favorite text editor (like Polaris Office or Simple Notepad, ...).

Note: I assume you are using also a cloud-Web solution like Dropbox, Copy, Drive, ... where you upload the Scilab scripts from your desktop computer, so you can download them to your smartphone when you want.

Labview and Scilab

2016-06-02T19:11:00.001+02:00

Labview generates .lvm files. Don't waste your time looking for dedicated Scilab scripts or functions for read this kind of files. You can easily read this files with the function csvRead.sci because the Labview files are just like Excel files in csv format.

If you use the csvRead function directly with only the name of the file as argument, you will obtain a vector or a matrix with NaN (the header and other comments) and the numerical data. With the function thrownan you can obtain a new vector or matrix without the NaN.

If you're looking for interfacing Labview with Scilab during the signal acquisition, you should take a look on "NI Labview to Scilab Gateway":

Too much Google+ will kill Google+

2011-08-06T11:42:00.001+02:00

A few weeks ago, I found that my Google+ stream was principally filled with posts about Google+ and Google products. At the beginning I though it was normal because everyone wanted to know how to use G+. For a moment I thought it was my fault because there were many Google experts on my circles. So I enlarged my circles to more subjects and I waited a couple of weeks to see if new G+ users were able to modifying the current trend with most varied articles about music, science, literature, etc. The problem was that these new profiles posted also articles about G+ each time they learned about some feature or new functionality. Therefore, even if I have actually almost 25 circles among which only one is for Googlers (Google employees), I keep finding a lot of Google+ tips, Google announcements and a lot of information about social networks and how Facebook and Twitter must be afraid of G+, or why you must keep your Facebook and Twitter accounts, ...

Yesterday I found a very interesting post of Alida Brandenburg that resumes very well the feelings of a large amount of G+ users about "too much G+" and she proposes a way to become more cultural, more social (for real). Hereafter I reproduce with permission her post and I hope you will find it very useful and instructive for your future G+ posts.

_______________________________________

Do you love Google+? Want it to succeed? You should probably stop posting about it then.

If you’re just joining Google+, you may not have noticed. In fact, if you did, you may have even appreciated it.

Studies show that 95% of posts on Google+ are about Google+.

Okay, okay, confession: I totally made that number up, but if you take a look at your stream, you’re likely to jump to a similar estimate.

Now, this is great for the first month or so that you’re on Google+ because these posts are chalked full of helpful tips that will assist you in getting your bearings in your new neighborhood. They are also often shares of pertinent information from users who are likewise useful to follow, so it’s a convenient, friendly introduction to your new neighbors. And really, come on- who hasn’t got caught up in the excitement of it all and wanted to do nothing but talk about this awesome new social community?

But now it’s your second month. You’ve settled into your new homepage and unpacked your box.netcontents. (Good thing you always backed up your Facebook photos on there!) You’ve become acquainted with your fellow Google+ residents and the all the usual characters (two crier, +Robert Scoble, Mayor +Natalie Villalobos … ). You’re feeling pretty jazzed about your move, so you venture out into your new ‘hood to explore further. But to your dismay, what you find resembles a track-housing, cookie-cutter community stamped out with nothing but more of the same- namely, posts about Google+. It’s stagnate. It’s starting to feel a little bit less like seven minutes in heaven and a little more like Fahrenheit 451. And it hits you: you just moved into a house of cards.

If Google+ continues to primarily offer Google+-related content, the site will get stale, established users will get turned off, and this house of cards will collapse. Reading about nothing but the way Google+ is or isn’t great, why or how it should be used, and how it’s going to impact the industry (and the world) is going to quickly become irrelevant. Without outside content to sustain users long-term, it’s simply not going to be great. Posts about how you should use Google+ are going to become empty if making said posts are the entirety of what users are using Google+ for. It will never have the opportunity to make an impact if all Google+ ends up being is a lot of smoke and funhouse mirrors reflecting back on itself. Pay no attention to the man behind the firewall.

So why am I saying all this? Because I do believe Google+ can be great. I do think there is an amazing plethora of reasons and ways Google+ should be used. I do think it has the potential to really serve as a game-changer and influence the world, and I’d like to see it reach that pinnacle.

So here’s my encouragement to all of you: if you share these sentiments, start branching out more. Post more unique, non-Google related content. Start sharing these non-Google/tech-related posts when you see them posted by other users so they can be disseminated to a wider audience, and likewise, think twice about sharing a Google+-related post “just because.” Build your stream up with people outside of the tech industry. Let’s not let this become a one-dimensional, Stepford-wives type community. Following the discouraging article that +Natalie Villalobos posted (https://plus.google.com/?tab=XX#109895887909967698705/posts/6rV72HNuXrD), let’s make this palatable and accessible on a global scale so it more accurately reflects our world population. Let’s focus on the plus, not the Google.

Why this isn’t likely to happen anytime soon.

Aside from noticing that most content on here is Google+-related, you may have also observed that the most-circled users fall into at least one of three categories:

1. Celebrities established prior to Google+
2. Google employees
3. People making Google+/tech-related posts

The first group is, of course, predictable, but the reason behind the second and third groups’ popularity is the biggest hurdle in overcoming the stagnation of content on here. Specifically, the people in the latter two groups rose to fame because their content or persona is Google+-related, and the posts that typically seem to get the highest number of shares, comments, and +’s are likewise Google+-related. This, again, is predictable, since this type of content is universally relevant to Google+ users, it’s accessible, and it’s still exciting and new to most. Compounding this advantage, these second- and third-category users then also become archived in a widely acknowledged database of “people to follow” list unofficially distributed to new users. This means that every time a new user joins, the elite status of the second and third groups is reestablished and further validated as more users follow them and distribute their posts. It’s amplification at its best. Suffice to say, posting G+-related content is not only easy, it’s also a tempting crutch to fall back on if you want to get a lot of followers.

Unfortunately, so long as people are rewarded by a high number of shares, comments and pluses on their Google+-related content, the positive reinforcement will continue and thus, so will the Google+ related content. People will continue to build notoriety on it and their egos will be fed. (See my previous post on this: https://plus.google.com/103765013042311928518/posts/F9bAU5K25Ec). This trend will keep up for a while until veteran users become frustrated with the redundancy and lack of substance on the site and an exodus will likely begin. The whole thing will potentially collapse.

How I plan to contribute.

Now, I realize the irony in all of this. First off, I’m encouraging others to expand their discussion points and stop relying so heavily on Google+ topics, while meanwhile making a post about Google+ myself. (Smoke and mirrors, smoke and mirrors.) Not only that, but as a first-gen user active on the site when it initially launched, I’ve inadvertently built a bit of a following myself due to my own generated Google+-related content. (So yes, I can see your eyes rolling from here.) And this is not to say that I'm going to stop posting about Google+ all together. Obviously as the site continues to develop, there will me be more discuss. However, thus far I’ve also intentionally done my best to post on a variety of other topics with as much thoroughness as possible to help spur discussion and add depth to the content on Google+. Here’s how I’d like it to continue:

Topic Tuesdays

Every Tuesday I’ll post a question or topic to spark discussion and sharing. It can be as simple as asking you to tell the story of the first time you got in trouble with your parents, or it can be something more controversial, like asking whether or not prostitution should be legal. You can respond to my post directly, but I would also encourage you to create your own post around it and share it with your circles. Stir things up. Tell a story. Discover and explore. Get to know each other and connect with one another on the things that make us human- from the trivial and mundane to the profound and poignant. In summary? Stop focusing on the Google and start cultivating the plus.

Ok, the costume is a little flashy and it's hard to imagine Linda Carter with tights blues.
Ok, we all had some concerns about David E. Kelly and canceled projects.
Ok, it was not easy to get used to the idea of a Wonder Woman with a Ally McBeal's life.
Ok, the world is in economic recession and we need to save money everywhere.
Ok, the pilot episode did not seem to match the wishes of the NBC.

Free Comic Book Day : Ma sélection

2011-05-09T18:52:00.000+02:00

Samedi était le Free Comic Book Day (FCBD) aux USA. Cet évènement, pas très connu en France, est très attendu par les lecteurs américains des comics. Heureusement quelques locaux français ont participé et j'ai eu la joie de récupérer quelques comics. Je salue vivement Pulp's Comics qui fête le FCBD comme il se doit avec des vrais comics gratuits, et non comme d'autres magasins qui offrent les comics participants sous condition d'achat d'autres comics. D'ailleurs tous les comics ci-dessus présentés (sauf le tout dernier) proviennent de Pulp's (merci encore d'avoir permis à mes enfants de vous dévaliser de 4 comics supplémentaires !). Dommage néanmoins que je n'ai pas réussi à trouver la figurine Heroclix de Green Lantern. Il semblerait que celle-ci n'a pas été fournie aux magasins français...

Black Hawk stealth helicopters seems to be used in Bin Laden's assault

2011-05-06T14:34:00.000+02:00

At least one of the helicopters used for reaching the Bin Laden compound in Abbottabad was a modified stealth version of the Black Hawk. Military and intelligence US agencies have refused to comment about the use of stealth aircraft in this mission. But the photographs of the helicopter that navy seals blew up (after it was damaged in a hard landing ?), indicates modifications on the tail section which could improve the stealth properties of the helicopter (click on image for enlarge).

Update :

During the countdown last Friday, engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU-1) (heaters are required to keep the APUs’ hydrazine from freezing on orbit).

The failure appears to be a power problem within the aft load control assembly-2 (ALCA-2), a box of switches controlling power feeds. This box will be replaced but action could take 2 days or more, then the new ALCA-2 should be tested. NASA presumes that Endeavour's launch will occur no earlier than May 10.

Je jure par Dieu, ma Patrie, mon Roi, que je remplirai suivant mes forces et capacités et, s'il le faut au péril de ma vie l'engagement suivant :

Aviateur, si je me vois confier un fardeau il me deviendra plus sacré que ma propre existence.

Pilote, si je vois confier un appareil de guerre je me battrai à visage découvert portant haut emblème et cocardes.

Aviateur, quelle que soit la machine fabuleuse inventée par l'homme et quels que soient les dangers, affres et tourments que présentera l'entreprise d'aller nager les galaxies je répondrai présent.

Pilote, je n'oublierai jamais que la machine n'est rien sans l'homme qui la dirige.

Si je remplis ce serment, qu'il me soit donné de nombreuses heures de vol, de nombreux moments d'exaltation dans les nuages ou de peur dans la nuit, des aubes radieuses, des tempêtes et des effrois à vaincre. Qu'il me soit donné de jouir heureusement de la vie et de ma profession, honoré parmi les hommes.

The future of radar systems : Quantum illumination

2011-04-03T17:21:00.001+02:00

Using entangled photons should be possible to improve considerably the data transmission. Raytheon BBN is studying new quantum concepts as quantum illumination for using in remote sensing applications. The development of such concepts would allow Radar, Laser Radar (LADAR), and other remote sensing systems to exceed the performance limits of today’s technology.

Actually traditional methods of data transmission, such as fibre optics or laser-based radar, require 100 photons to transmit a single bit of data. Using quantum illumination should be possible to sent 10 bits on a single photon. This discovery was announced theoretically by Seth Lloyd of the W.M. Keck Center for Extreme Quantum Information Processing (xQIT) 3 years ago. Here after the abstract of his paper Quantum Illumination :

Abstract: The use of entangled light to illuminate objects is shown to provide significant enhancements over unentangled light for detecting and imaging those objects in the presence of high levels of noise and loss. Each signal sent out is entangled with an ancilla, which is retained. Detection takes place via an entangling measurement on the returning signal together with the ancilla. Quantum illumination with e bits of entanglement increases the effective signal-to-noise ratio of detection and imaging by a factor of 2^e, an exponential improvement over unentangled illumination.

It's all about entanglement. In this phenomenon when you have a pair of photons the quantum state of one photon is linked to that of another, regardless of how far apart they are. Quantum illumination begins with researchers passing a laser through filters that thin the beam into photons. The filters create identical photons that are linked to each other. Then they split the entangled photons and release one at a target, while the other is keeping near the transmitter. When a photon hits the target, it bounces back towards the source in a process that alters the photon. When it returns to the detector, the altered photon is no longer strictly entangled with its pair, then scientists compare the released photon’s reflection to its unaltered twin. This process is not very different from classical radar, where electromagnetic waves rebound off targets in order to create an image. However the smaller photon delivers far more data far more quickly and efficiently.

As said by researchers at Raytheon BBN, quantum illumination could be used to create hyper-long-distance communications systems where large amounts of information could be sent more quickly (almost instantaneously) and clearly. Some enthusiastic researchers suggest that quantum illumination could lead towards teleportation devices. That's right, but only for information. Star Trek's teleportation of people and objects remains on Science Fiction for the moment...

A definition for quantum illumination which comes from paper Quantum Illumination by Seth Lloyd :

Quantum illumination is a potentially powerful technique for performing detection and imaging, in which signal is entangled with an ancilla, and entangling measurements are made at the detector. Entanglement enhances the eﬀective signal to noise ratio because a noise photon has a d times harder time masquerading as an entangled signal photon, compared with a noise photon masquerading as an unentangled signal photon.

The enhancement of sensitivity and eﬀective signal-to-noise ratio that quantum illumination provides is exponential in the number of bits of initial entanglement, and persists even in the presence of large amounts of noise and loss, when no entanglement survives at the receiver.
