Everything you need to know about Xamarin
- select the contributor at the end of the page -
Thank you to everyone who attended our Making cross-platform mobile apps a reality with Xamarin and C# webcast. The webcast is still available for viewing if you missed it or would like to watch again. We had so many viewers that there wasn't time to respond to everyone's questions. So, to be sure that all questions are addressed, I've provided answers below to all of the questions we received. For ease of reading, similar inquiries have been combined.
To continue learning about Xamarin, view Part 1 and Part 2 of our intro to Xamarin development course.
Q) Does Xamarin support the iOS App Store and Android Google Play Store?
Yes. Apps written with Xamarin can be deployed through all of the usual channels for iOS and Android apps. Xamarin has the same distribution capabilities and limitations as native apps. Production iOS apps must still be distributed through the iOS App Store; Production Android apps are normally distributed through the Android Google Play store, but also support other app stores and side-loading, just as native apps do. The same beta distribution platforms available to native apps, such as TestFlight and TestFairy, are available for Xamarin apps.
Q) Is there a cross-platform database available?
Yes, Sqlite.
Q) Does Xamarin support ADO.NET?
Yes, Xamarin provides ADO.NET for the Sqlite database
Q) Does the Xamarin Studio / Visual Studio iOS Designer support storyboards?
Yes, both Xamarin Studio and Visual Studio support storyboards in the iOS Designer.
Q) Does Xamarin iOS designer support auto-layout?
Q) Does Xamarin provide support for dealing with the many different versions of the Android OS?
Yes. Xamarin provides access to the standard Android features used for dealing with these issues, such as the Android Support Libraries, Fragments and feature-specific resource files, among others.
Q) Does Xamarin support iOS 64-bit?
I believe so. Xamarin has a long discussion on the issue.
Q) Does Xamarin support iOS 7?
Yes. Xamarin has an excellent history of providing support for new platforms and platform updates. Xamarin provided support for the latest releases of iOS, Android, Google Glass and Amazon Fire the same day each of them were released.
Q) Does Xamarin support Windows Phone?
Xamarin is .NET, and cross platform project types like Portable Projects and Shared Projects will run across Windows Phone, iOS and Android.
Technically the Windows Phone support is provided by the Microsoft tools; the iOS and Android support is provided by Xamarin. For the most part, those details are behind the scenes. As developers, we create a cross-platform project, write cross-platform compatible .NET code, and that code runs across iOS, Android, and Windows Phone.
Q) What Platforms does Xamarin.Forms support?
Xamarin.Forms runs across iOS, Android and Windows Phone.
Q) Do I need a Mac to develop for iOS?
The short answer is yes. Xamarin relies on the underlying iOS build tools provided by Apple, and those tools only run on Mac/OSX.
If you are using Visual Studio for your development, you are able to develop code, debug, design your UI, etc. within Visual Studio on your Windows computer. The Mac computer is used as a build server, which Visual Studio communicates to through your network.
If you are using Xamarin Studio, you must perform all of your iOS-specific development directly on the Mac computer. Code that will be shared between iOS and Android can be written in Xamarin Studio on your Windows computer and shared or copied to your Mac for inclusion in the iOS build of the app.
Any Mac running OSX 10.7 (Lion) or above will work. I personally use a MacBook Pro but I'm aware of other developers who use a MacBook Air.
Q) How does Xamarin Licensing work?
Xamarin is available in four editions (Starter, Indie, Business, Enterprise). The Starter edition is free and has some limitations on application size. The Business and Enterprise editions include Visual Studio support.
Xamarin licenses are per platform, so developing for both iOS and Android requires two licenses. Xamarin offers discounts for MSDN subscribers, but I've recently been told that Bizspark MSDN subscriptions do not qualify.
Xamarin is sold through a one year license subscription. The subscription is required to receive updates. If you purchase a subscription and do not renew it, your Xamarin tools will continue to work, but you will stop receiving updates.
Q) Which edition is right for starting out, or for becoming familiar with Xamarin?
Newbies and home-based developers should go with the Starter Edition since it's free.
For developers interested in building enterprise-grade apps using Visual Studio, check out the free trial of the Business Edition. A 30-day free trial of Xamarin Business Edition is available to everyone; MSDN subscribers get a 90-day free trial of Xamarin Business Edition, which is plenty of time to build a proof-of-concept app.
Q) Do I have to build for both iOS and Android at the same time?
No. You can initially target just one platform such as iOS, and then later include Android. The key is that you need to create a cross-platform compatible project type such as Portable Class Library or Shared Library and include the code you'd like to eventually run across both platforms in that project.
Q) Does Xamarin allow in app purchases?
Yes it provides support for both the iOS and Android purchasing libraries.
Q) What limitations does Xamarin put on app development that is not in the standard platform tools?
Xamarin itself has none that I can think of. Xamarin does an incredible job of providing access to the underlying platforms. It has close relationships with the platform manufacturers and is able to ship updates to Xamarin inline with updates to the platforms. Xamarin shipped support for the latest releases of iOS, Android, Google Glass and Amazon Fire the same day each of them were released.
The one issue I have encountered has been with third-party libraries. Some libraries that target Android and/or iOS do not provide Xamarin wrappers and are not directly callable from Xamarin. You are still able to access such libraries by manually writing Xamarin bindings for them, but that's obviously extra work. The good news is that more and more third-party products are providing Xamarin support.
Q) Can iOS Objective-C code or Android Java code be imported into Xamarin?
Xamarin provides a binding mechanism that allows you to call into libraries that are written in iOS Objective-C or Android Java. Such libraries are fully accessible from Xamarin once the bindings are created. However, Xamarin does not provide source-code support for Objective-C/Java.
Q) Where can I find instructions for how to setup a Visual Studio environment that uses Xamarin for cross-platform iOS/Android development?
Xamarin provides information on its website. We also walk through the setup in our Building cross-platform iOS/Android apps with Xamarin, Visual Studio, and C# - Part 1 course.
Q) Will the new iOS Swift programming language impact Xamarin?
I don't think Swift will have a significant impact on Xamarin. Xamarin's strengths are cross-platform development productivity, and the ease with which .NET developers can transfer their skills to mobile development. Swift doesn't target either of these issues.
Q) Does Xamarin simplify cross-platform geolocation?
Xamarin provides a component called Xamarin.Mobile that includes geolocation support. The component works well for receiving location updates. It does not provide direct support for more sophisticated geolocation needs. In those cases, you'll need to use each platform's APIs.
Q) As an experienced mobile developer who is already familiar with native development on both iOS and Android, what attracted you to Xamarin?
For me there were three main attractions:
The ability to share code across platforms
The ability to bring existing business logic from server and/or desktop .NET apps directly into a mobile app without rewriting it
When consulting for teams with server and/or desktop .NET experience, Xamarin significantly eased their transition to mobile development
Q) How are Xamarin Studio Portable Class Libraries different from those in Visual Studio?
There is no difference. You can literally create a Portable Class Library (PCL) in Xamarin Studio and then open it in Visual Studio (provided you have the Xamarin plug-in); you can also do the reverse. The Android and iOS support for Visual Studio PCLs is actually provided by the Xamarin plug-in.
Q) What's the difference between Portable Class Libraries and Shared projects?
The short answer is that Portable Class Libraries are projects that build an assembly that supports multiple platforms. Shared projects don't create an assembly; rather their code is, in effect, brought into projects that reference them. This MSDN blog provides an extensive discussion.
Q) How does Xamarin performance compare to native apps?
I've experienced no noticeable performance impact versus native in the work I've done. In looking at online stats, Xamarin on Android runs just as fast as native in most cases and is sometimes even slightly faster (this is possible because some Xamarin code runs outside of the standard Android runtime). There were some performance issues with Xamarin on some older Android devices but no longer. I haven't seen any stats on iOS, but, again, I have not experienced any issues.
Q) Will Pluralsight have more courses on Xamarin and Xamarin Forms?
I (Jim wilson) currently have an intro to Xamarin course split into Part 1 and Part 2. I also have a Google Glass with Xamarin course about to come out. The next course I'm going to create is on Xamarin.Forms, slated to launch later this summer. I know other Pluralsight authors are also working Xamarin-relaed courses, so stay tuned for more.

Writing a book or a short story is like a relationship. You meet a pretty girl (you think of a cool idea for a plot). You discover the girl is super smart and intelligent (the idea has depth and resonance, and is compelling), and you become even more attracted to her. You start on page one (you ask her out), and there begins your relationship in earnest. Your first several dates go off without a hitch, and you make good progress on the first draft. The relationship grows and blossoms.
Without extending this metaphor into the realms of the surreal, you fall madly in love (you get into the zone of writing the story), and love (your writing) flows as poetically as a Shakespearean sonnet on a summer's day.
But, unlike in the real world, your relationship with your story is doomed to failure because, at some point, the relationship has to end. It must end. You can't keep writing the same story for the rest of your life. There has to be closure. We writers sometimes spend so much time with our creations, they are describable as significant others: loved and cherished, honored and obeyed, and breaking up can be hard to do.
Sometimes, the breakup might be mutually beneficial, especially when the story has been a hard write, and there's been a lot of bickering between you and it in the course of its telling. You know those stories, the ones with lots of long silent nights sat staring at each other, with nothing to say. And you're just mopping up the loose ends, to get it over with, so you can go your separate ways, with both hoping to survive the bitter separation.
Worse, still, is when you leave the story for another. And it sits there, alone, in the café of your soul, drinking endless cups of coffee waiting for your return. And when you do return (after your torrid affair with another story), it's never the same.
For most writers, writing is rewriting. I think only in movies (and in our dreams) does anyone start on page one, spend a couple of months working through to page 400, type in THE END, and then send the completed book off to a publisher (where, of course, it immediately sells and is immediately published)). The first draft is merely the gateway into the story. The real writing comes in the rewriting.
But rewriting can't last forever. How many times can you read over a story and refine it and polish it? Every time through you find something new to fiddle with and adjust: another adverb to throw out, another debatably redundant word or phrase to toss, another he said or she said that can be dropped, because it's quite obvious who is talking.
And every time you get to the end of a read over, you think, yeah, let's do this just one more time.
The best way to end a story is at the train station.
You're about to board the train (to continue on your journey), and your story is going to wave goodbye from the platform. You both know it can't go on, that you must part, that it's over. You're done. All that needs to be said has been said, and you both know it.
The encounter, albeit brief, has come to an end.
To actually go ahead and shunt this metaphor firmly into the realms of the surreal, your story then becomes your child.
It goes off on its own, and you have little or no more control over it. All you can do is sit back and watch as it grows and makes its way in the world.
Hopefully, it'll graduate from high school (i.e., sell and get published). Hopefully, at least, somebody might say some nice things about it. It might even get lucky and get nominated for an award; it might even win one.
It might even mature into an adult and get picked up by another medium: audio, film, theater, computer game (and who knows what else awaits us in the future). And it might even one day grow up to be considered something rather special: an outstanding story among its peers.
And one thing is absolutely for certain: no "mights "about it. Your story will outlive you. And long after you have gone, someone somewhere may still know of it, have a copy in his or her hand, and perceive a sense of the love that once bloomed.

Q: spray-testkit === status passes whatever status is I have following test in spray-testkit with scalatest and I do not understand why test passes every time despite the actual status.
import akka.actor._
import akka.event.LoggingReceive
import akka.testkit.TestProbe
import com.ss.rg.service.ad.AdImporterServiceActor.{GetImportStatus, StatusOfImport}
import org.scalatest.{MustMatchers, WordSpecLike}

class AdServiceApiTest extends WordSpecLike with MustMatchers with ScalatestRouteTest {

  "AdService REST api " must {
    "POST for import with mandatory parameters should be processed" in {
      val p = TestProbe()
      val addressServiceMock = system.actorOf(Props(classOf[AdServiceActorMock], p.ref))

      Post("/service/ad/import?adId=1") ~> new AdServiceApi(addressServiceMock).route ~> check {
        handled must be(true)

//        rejections must have size 1
        response.status === StatusCodes.NotAcceptable
      }
    }
  }

Test passes even though that status should be different and when I made the test failed for obvious reason like rejection ... the error msg is follows:
Request was not rejected, response was HttpResponse(202 Accepted,HttpEntity(text/plain; charset=UTF-8,The request has been accepted for processing, but the processing has not been completed.),List(),HTTP/1.1)
org.scalatest.exceptions.TestFailedException: Request was not rejected, response was HttpResponse(202 Accepted,HttpEntity(text/plain; charset=UTF-8,The request has been accepted for processing, but the processing has not been completed.),List(),HTTP/1.1)
    at spray.testkit.ScalatestInterface$class.failTest(ScalatestInterface.scala:25)

Seems that I am missing some important concept here.
Could someone please clarify?
UPDATE: Following works correctly
status must equal(StatusCodes.Accepted)

A: === is not enough.  You have to write
status should === (StatusCodes.NotAcceptable)

or
assert(status === StatusCodes.NotAcceptable)

Optimal control under uncertainty has been one of the central research topics in the control community for decades. While a number of theories have been developed to control a single state from an initial state to a target state, in some situations, it is preferable to simultaneously compute control commands for multiple states that start from an initial distribution and converge to a target distribution. This dissertation aims to develop a stochastic optimal control theory that, in addition to the mean, explicitly steers the state covariance. Specifically, we focus on the control of linear time-varying (LTV) systems with additive Gaussian noise. The task is to steer a Gaussian-distributed initial system state distribution to a target Gaussian distribution, while minimizing a state and control expectation-dependent quadratic cost under probabilistic state constraints. Notice that, in such systems, the system state keeps being Gaussian distributed. Because a Gaussian distribution can be fully described by the first two moments, the proposed optimal covariance steering (OCS) theory allows us to control the whole state distribution and quantify the effect of uncertainty without conducting Monte-Carlo simulations. We propose to use a control policy that is an affine function of filtered disturbances, which utilizes the results of convex optimization theory and efficiently finds the solution.
After the OCS theory for LTV systems is introduced, we extend the theory to vehicle path planning problems. While several path planning algorithms have been proposed, many of them have dealt with deterministic dynamics or stochastic dynamics with open-loop uncertainty, i.e., the uncertainty of the system state is not controlled and, typically, increases with time due to exogenous disturbances, which may lead to the design of potentially conservative nominal paths. A typical approach to deal with disturbances is to use a lower-level local feedback controller after the nominal path is computed. This unidirectional dependence of the feedback controller on the path planner makes the nominal path unnecessarily conservative. The path-planning approach we develop based on the OCS theory computes the nominal path considering the closed-loop evolution of the system uncertainty by simultaneously optimizing the feedforward and feedback control commands. We validate the performance using numerical simulations with single and multiple vehicle path planning problems.
Furthermore, we introduce an optimal covariance steering controller for linear systems with input hard constraints. As many real-world systems have input constraints (e.g., aircraft and spacecraft have minimum/maximum thrust), this problem formulation allows us to deal with more realistic scenarios. In order to incorporate input hard constraints in the OCS theory framework, we use element-wise saturation functions and limit the effect of disturbance on the control commands. We prove that this problem formulation also leads to a convex programming problem and demonstrate the effectiveness using simple numerical examples.
Finally, we develop the OCS-based stochastic model predictive control (CS-SMPC) theory for stochastic linear time-invariant (LTI) systems with additive Gaussian noise subject to probabilistic state and control constraints. In addition to the conventional terminal cost and terminal mean constraints, we introduce terminal covariance constraints in the stochastic model predictive control theory. The OCS theory efficiently computes the control commands that satisfy the terminal covariance constraints. The key benefit of the CS-SMPC algorithm is the ability to ensure stability and recursive feasibility of the controlled system even when the system has unbounded additive Gaussian noise. In addition, the proposed CS-SMPC theory is computationally less demanding than previous SMPC approaches. In order to verify the effectiveness, the CS-SMPC theory is applied to the problem of self-driving vehicle control under uncertainty.

La fusillade de North Hollywood fait référence à un échange de coups de feu survenu entre deux braqueurs puissamment armés et protégés (Larry Eugene Phillips et Emil Dechebal Matasareanu) et des policiers et membres du SWAT du Los Angeles Police Department (LAPD) le . Durant cette fusillade, 12 agents de police et 8 civils furent blessés par balle et les deux braqueurs tués.

Braquage
L'attaque a lieu à 9 h 15 dans une agence de la Bank of America du district de North Hollywood, à Los Angeles, Californie, États-Unis. À ce moment sont présents dans les locaux dix employés et une trentaine de clients quand les deux braqueurs font irruption arme au poing. Regroupant les otages dans un coin de l'agence, ils se font remettre sous la menace la somme de .

Durant le braquage, un des employés est blessé à la tête par un coup de crosse d'AKM que lui inflige un des braqueurs. C'est une personne passant près de l'agence qui donne l'alerte. L'argent volé par les deux suspects sera rendu inutilisable par le système anti-effraction du sac contenant les billets et consistant à marquer à l'encre indélébile les coupures.

Fusillade
Cette fusillade est restée dans les mémoires de la police notamment par l'armement et l'équipement des deux suspects. En effet, Phillips et Matasareanu étaient armés de pistolets Beretta 92F mais surtout de Norinco 56S et d'un HK 91 (modifiés illégalement pour tirer en rafales), ils portaient des gilets pare-balles couvrant le torse ainsi que des protections en Kevlar faites maison pour protéger leurs bras et leurs jambes.
Le duo de braqueurs est sorti de la banque armés d'AKM chinois et d'HK 91 et s'est retrouvé face à des agents de police venus vérifier la situation quand la fusillade a commencé. En seulement 5 minutes, trois civils et neuf agents de police étaient blessés quand une alerte tactique a été décidée.

Finalement, ce sont 370 policiers du LAPD (SWAT compris) qui étaient sur les lieux. Les suspects ont tiré approximativement  alors que les policiers ont tiré 650 balles, faisant de cette fusillade une des plus violentes de l'histoire de la police américaine.

Évènements
Tentant de fuir, les deux suspects ont utilisé une voiture pour couvrir leur fuite mais ont été obligés de se séparer.
Philipps a dû arrêter de tirer avec son AKM en raison d'un «  » (un blocage du mécanisme de tir dû à un étui mal éjecté) et a continué en utilisant son pistolet Beretta 92F. Il a tiré au pistolet sur des policiers qui ont riposté. Touché à la main droite, il a lâché son arme. Après avoir ramassé son arme avec la main gauche, il a continué de tirer en direction des policiers puis s'est abrité derrière un camion. Peu après, il a placé le canon de son arme sous son menton et semble s'être tiré une balle en même temps qu'un coup de feu tiré par la police le touchait à la colonne vertébrale.
La question reste de savoir si Phillips s'est volontairement donné la mort ou s'il a involontairement pressé la détente quand sa colonne vertébrale a été touchée alors qu'il essayait de recharger son arme à une main.

Matasareanu a été grièvement blessé par des policiers du SWAT alors qu'il tentait de s'enfuir à bord de la première voiture volée. Il a braqué un pick-up de passage et a transbordé ses armes de la voiture dans le pick-up. Il a toutefois été dans l'impossibilité de démarrer le pick-up (son propriétaire avait installé un coupe-circuit qu'il avait activé). Une voiture du SWAT s'est approché du pick-up et une nouvelle fusillade a éclaté entre Matasareanu et trois agents du SWAT, séparés par moins de 10 mètres. Perdant beaucoup de sang de ses 29 blessures (dont plusieurs aux jambes), il s'est rendu après avoir épuisé toutes les munitions de son HK 91. La police a appellé une ambulance mais Matasareanu a succombé à ses blessures avant qu'elle n'arrive sur les lieux.

Épilogue
Durant les échanges de coups de feu, un total de 12 policiers et 8 civils furent blessés (dont certains grièvement) et deux morts sont à décompter (Phillips et Matasareanu).
On reprocha plus tard au LAPD le fait que Matasareanu n'ait pu recevoir des soins médicaux immédiatement, ce qui aurait pu lui sauver la vie. Ce à quoi la police répondit que le personnel ambulancier suivait les procédures standard en cas de situations hostiles, à savoir refuser de pénétrer la "zone rouge" car Matasareanu était alors encore considéré comme dangereux. De plus, il avait été fait mention d'autres suspects dans les parages, ce qui a retardé l'arrivée de l'ambulance. Il s'avèrera plus tard que les signalements concernaient des policiers en civil portant des gilets pare-balles.

Cette fusillade a des similitudes avec la fusillade de Norco (Californie), le 9 mai 1980.

Le 14 juin 1995, Phillips et Matasareanu avaient déjà braqué un fourgon blindé, tuant un convoyeur de fonds et blessant gravement le second.

Conséquences
La fusillade a mis en évidence le déséquilibre grandissant entre les moyens à la disposition de la police et ceux employés par les criminels. Des documents vidéo de l'incident montraient les balles de la police frappant les suspects avec peu ou pas d'effets, en grande partie en raison des protections portées par les suspects qui pouvaient sans problème arrêter les projectiles en calibre 9 mm et .38 de la police ainsi que les cartouches à grenaille en calibre 12.

Cette inefficacité des balles de pistolet à traverser les gilets pare-balles des suspects a eu pour effet aux États-Unis d'armer des agents de police sélectionnés avec des M16, modifiés pour ne pas tirer en rafales, lors des patrouilles. Le choix de ce type d'armes donnait aux premiers intervenants une plus grande capacité à affronter efficacement et neutraliser éventuellement des suspects fortement armés et protégés.

Les partisans du contrôle des armes à feu aux États-Unis ont cité cet incident comme la preuve que la législation actuelle sur les armes à feu était inefficace pour empêcher que des armements de type militaire ne finissent entre les mains de criminels déjà condamnés. Les opposants aux lois de régulation des armes invoquaient le fait que ces armes avaient été à la fois acquises illégalement et modifiées illégalement pour tirer en rafales et que cet incident n'indiquait pas que l'utilisation criminelle d'armes automatiques légalement déclarées était un problème.

The Virginia Small Business Financing Authority (VSBFA) is doing a poor job issuing loans for small businesses with millions in unused funds available, according to a new report by the Joint Legislative Audit and Review Commission (JLARC) released Monday.
The VSBFA is a part of the Virginia Department of Small Business and Supplier Diversity, but operates separately from the rest of the agency.

Forming HEdpAY Alliance Group for adoption of crypto banking
Traditional banks and financial institutions, many are looking to a new ways and technologies to expand in this new era of blockchain — and this includes currencies, banking and investments. Founder and CEO of HEdpAY, a pioneering company in connecting traditional banking and the crypto world, announcing creating of alliances in various sectors of business globally to provide financial services solution with the crypto banking ecosystem in the global market.
Both traditional banks and crypto banks have their place, and, with the current mood of distrust, they need each other. There is a bridge that needs to be built to align both." Future banking operators like HEdpAY are building a platform that connects crypto with fiat currencies and supports decentralised control. First tests and business adoptions start by using HEdpAY systems to overcome these challenges and bring crypto use to the mass market, starting with SMEs, funding them and financing their projects with HEdpAY.
One of the major alliances and partners to start the HEdpAY Future Banking Solution is "LIKER" Liker world Ltd in the education sector.
Education is the power of modern society and builds the future generations, Therefore HEdpAY with Liker has created a possibility to study anywhere and anytime you want.
Liker is an educational blockchain-based content platform. Users not only get access to all educational materials and activities but also get rewarded as they study.
With the help of HEdpAY LIKER application, users can learn, get rewards, and grant their funds to educational projects for their future within the network.
HEdpAY signed an alliance partnership agreement with LIKERWORLD, as e-banking solution company based in London, the home of Fintech, and completed a $500,000 mutual investment. With the 2020 Tokyo Olympics in sight, Alliances plan to utilize the e-banking system, a superior block chain of Hedpay Ltd, to support real-time transactions through POS, ATM devices and crypto prepaid cards. To this end, Solomon Capital Japan, which obtained permission to transfer money from Japan's Financial Services Administration, joined the Alliance Group. The company is already in business with a company that has acquired BitLicense in New York, leveraging Hedpay Ltd. technology in the UK, Japan, New York, Asia, Russia and European markets.
QUOTE: "Education for future generations will bring crypto to the mass market adoption".
HEdpAY is one of the first projects connecting traditional bank and the crypto world, and one of the first to be creating investment funds in crypto, with the alliance group globally, in order to maximise profits and minimise losses," explains Vicken. It has been created to be the first and most authoritative financial institution enabling users to transfer their fiat currency in crypto quickly, safely and compliantly, using the following services: current account, debit card and exchange.
HEdpAY also gives investors exclusive funding opportunities: creating their own blockchain, helping entrepreneurs and SMEs developing new projects following detailed compliant protocols, and then by selecting the best projects and evaluating their currencies that already included in the market, to finance them and fund their future plans.
The company's goal is to showcase how its futuristic solution between crypto and traditional banking to revolutionise a financial system, that is still anchored to old banking standards," in the words of Vicken. He believes that the real opportunity is the benefits blockchain can bring to the financial services industry. "While crypto market has witnessed saturation over the past few months, the real opportunity is more about the benefits that blockchain can bring to financial services and crypto banking. The major industries are primed for the integration of blockchain technologies. Other opportunities can be seen in education, medication, genetic analytics, voting, forecasting, government, crowdfunding, retail and real estate. I think the possibilities are endless".
QUOTE: "…Educate the future generation to revolutionise traditional old systems in finance and all other possibilities"
Despite the perceived negativity around cryptocurrencies in regard to the puzzle of jurisdictional risk and regulation, Vicken is positive about the future of crypto and blockchain, whilst establishing and cultivating compliant relationships with the regulatory bodies, global financial, educational, medical institutions and businesses. "HEdpAY's purpose is to provide the services of the modern traditional bank whilst implementing the prospects of a bank for cryptocurrencies, and at the same time ensuring better regulation of the cryptocurrency market and its use, said Vicken."
In the past year HEdpAY has reached some significant milestones, most recently the company announced its Partnerships and Alliance groups for the creation of biggest fund in crypto banking system. The company offers a pallet of project finance by its Hdp.ф Tokens
· A residential property development in Italy, named "Green Park", environmentally friendly and fully green ecosystem, budgeted the equivalent of 40 Million Euros in Hdp.ф, will be built and financed by HEdpAY banking system on blockchain.
· An educational system joined with LikerWorld Ltd. For the future generation have the full capacity and means to be educated, where ever they are and how ever their situation be,
· A medical cosmetic research and development, product production for anti-aging using biotechnologies and eco-friendly products, financed and supported by HEdpAY systems on blockchain.
"Hdp.ф tokens will be used within the HEdpAY projects ecosystem to ensure success of the future banking solution and the development work on our revolutionary platform ongoing with various projects and plans toward the future, added Vicken."
Going forward, the company's ambition remains undimmed. "HEdpAY has an exciting future ahead in terms of the completion of our targeted goal, the future launch of the HEdpAY Alliance Group Fund and our full set of banking services," says Kaprelian. "In a year's time, we would like to see the crypto banking mass adopted, thanks to our pilot projects and for the wider benefits that can be realised through blockchain technology."

Review: The Conspirator
April 28, 2011 / Dave Taylor / Dad at the Movies / No Comments
We all know that the actor and Confederate sympathizer John Wilkes Booth (played in The Conspirator by Toby Kebbell) assassinated US President Abraham Lincoln (Gerald Bestrom) and was later killed during capture by Union soldiers, but did he work alone? It'll come as a surprise to many people that he was part of a much greater plot that also involved the planned assassination of Vice President Andrew Jackson (Dennis Clark) and Secretary of State William Seward, neither of whom was killed, though Seward was stabbed repeatedly.
The conspiracy that surrounding Lincoln's assassination is perfect for a historical film and director Robert Redford delivers an excellent drama with The Conspirator, one well worth watching both for its historical value and because it's just a darn good film with more than one surprise twist.
The film centers on Mary Surratt (Robin Wright), mother of conspirator John Surratt (Johnny Simmons). By running a boarding house in Washington DC where the conspirators hatched their plot, was she therefore culpable as an accomplice? The heads of the military tribunal, Judge Advocate General Joseph Holt (Danny Huston) and Secretary of War Edwin Stanton (Kevin Klein), clearly believe she's guilty and that the pretense of any trial is a waste of time, but was Mary truly guilty?
The thankless task of defending her rests with newly graduated lawyer Frederick Aiken (James McAvoy), who wrestles with matters of constitutional fairness (why a military tribunal when the accused is a civilian?) and the negative social effects of defending a much hated woman in a public court of inquiry, along with his own questions of her guilt or innocence. A former Union soldier, there's an additional layer of conflict with his peers as he professes his belief that Mary is, in fact, innocent of knowledge of the conspiracy.
The events of the film take place in late 1865, as the Civil War is winding down. As with any war, the truce has been signed but not every Confederate soldier has accepted their defeat, and it's from this seed that the conspirators hatch the idea of kidnapping the President to sow confusion into the Union government, a last hurrah, as it were. But when President Lincoln changes his travel plans unexpectedly, the plot takes a fatal turn from kidnapping (the original plan was to hold Lincoln hostage in return for the release of all Confederate soldiers in Union jails) to murder.
An interesting story and momentous events don't make a great movie, however. That comes from a smart script, able actors, an ability to recreate the times and setting and a director, cinematographer and wardrobe team that can make us not only feel we're seeing events as they happened, but become engaged in the story. Redford and his team (writer James Solomon and Gregory Bernstein, cinematographer Newton Sigel and costume designer Louise Frogley) have pulled together all of these ingredients and delivered one of the most compelling historical dramas that's made it to the silver screen in quite a while.
Mary Surratt (Robin Wright) and Frederick Aiken (James McAvoy) from The Conspirator
Having said that, it's also fair to point out that the film starts out slowly and lags at times. Courtroom dramas are tricky and though much of the film is flashbacks and events external to the tribunal, the trial of Mary Surratt on the charge of conspiracy to assassinate the President, and her spirited defense by Frederick Aiken is central to the film and definitely not to everyone's tastes.
Still, in an era where movies are defined by special effects and explosions, it was a pleasure to watch a well-acted, well-staged historical drama that both illuminated an important and fascinating moment in American history and entertained the appreciative audience. I recommend it.

The launch announcement that wasn't supposed to be announced concerns two new budget Moto smartphones released by T-Mobile July 27th. A leak by T-Mobile showcases the Moto E5 and Moto E5 Plus, both are expected to be under $200 and will be available at the end of the week.
While the price has yet to be confirmed, but we're fully expecting the Moto E5 to come in around $100 while the E5 Plus which will be a larger version to come in around $200.
The specs of both phones have yet to be disclosed but expect to see dual cameras and comparable specs of a traditional budget-friendly smartphone.
Both the Moto E5 and Moto G6 series have been confusing since their debuts. Some variants have been geo specific while others carrier specific, and no one has been able to follow the release of either.
Both the Moto E5 and Moto E5 Plus are expected to be carrier releases through T-Mobile. If interested, check out the T-Mobile website July 27th for more through this link.

Phase stability and transformations in the halide perovskite CsSnI3

Centre for Sustainable and Circular Technologies (CSCT)
EPSRC Centre for Doctoral Training in Statistical Applied Mathematics (SAMBa)
We employ the quasiharmonic approximation to study the temperature-dependent lattice dynamics of the four different phases of cesium tin iodide (CsSnI3). Within this framework, we obtain the temperature dependence of a number of structural properties, including the cell volume, bulk modulus, and Grüneisen parameter. The Gibbs free energy of each phase is compared against the temperature-dependent Helmholtz energy obtained from the equilibrium structure within the harmonic approximation. We find that the black tetragonal perovskite phase is not dynamically stable up to at least 500 K, with the phonon dispersion displaying negative optic modes, which pass through all of the high-symmetry wave vectors in the Brillouin zone. The main contributions to the negative modes are found to be motions of the Cs atom inside the perovskite cage. The black cubic perovskite structure shows a zone-boundary instability, indicated by soft modes at the special q points M and R. These modes are present in calculations at the equilibrium (0 K) lattice constant, while at finite temperature additional negative modes develop at the zone center, indicating a ferroelectric instability. The yellow crystal, composed of one-dimensional (SnI6)n double chains, has the same heat of formation as the orthorhombic perovskite phase at 0 K, but becomes less energetically favorable at higher temperatures, due to its higher free energy.

The Jewel of Flatbush: Tour the Historic Kings this Weekend
BY Scott Enman / 7/9/2019 9:21:25 PM
Brooklynites will have the unique opportunity to explore the historical Kings Theatre on Saturday, on one of only three currently scheduled tours of the Jewel of Flatbush Avenue.
Attendees will receive unfettered access to the newly renovated theater, initially designed to resemble a faux palace at Versailles with elegant staircases, marble floors, mahogany trim and a lavish rouge grand drape.
Barbra Streisand called it "one of those grand old movie palaces" — and indeed it was. When it opened in 1929, it was Brooklyn's third-largest movie house with 3,676 seats. It hosted Vaudeville acts, silent films and talking pictures.
In addition to walking around the beautiful building, patrons will be able to learn the history of the theater and the backstory of its transformation. All of the tour guides are from the theatre's neighboring community.
"Reliving the history of Kings as well as being a part of its present and future gives me a sense of pride knowing I'm continuing that history of being a pillar of Brooklyn," said tour guide David Williams.
The 68,000-square-foot theater was seized by New York City for unpaid back property taxes and eventually closed in 1977. Its last film was about Bruce Lee.
For decades, it sat empty and fell into disrepair. Dust collected and the inside grew dilapidated from the elements.
In 2010, however, under the guidance of then Brooklyn Borough President Marty Markowitz, the theater underwent a $95 million renovation thanks to a group of city, state and private entities, including the city's Economic Development Corporation and the Kings Theatre Redevelopment Company.
It was listed on the National Register of Historic Places in 2012 and reopened on Jan. 23, 2015, with the first performance starring Diana Ross on Feb 3.
"Brooklyn is a treasure box full of history and Kings Theatre is one of its brightest gems," said tour guide Bil-Qis Coleman. "Being a part of its present is a gift. Being [part of] its future, gives me the chance to help it shine brighter. But being a voice to share its rich past is priceless. It's history in the remaking."
Tours will be given on June 29, July 20 and July 27. They start at 2 p.m. at 1027 Flatbush Ave. More tours are expected to be announced in August.

When I moved from Maine to New Hampshire I wanted to get to know other local business owners in Mount Washington Valley. After dining at the Thompson House Eatery last year, I knew this was a place I wanted to photograph. When I emailed the general manager, Meghan Moody, about the opportunity, I had no idea I'd be walking away with not only new friends in the valley, but some of the most genuine people I've ever met.
Jeff Fournier, Chef/Owner + Kate Fournier, Owner.
When you dine at the T.H.E. you feel like family. This focus on family goes deeper than just the restaurant, as owners Kate and Jeff Fournier live on the other side of the wall. The stunning 1790's farmhouse on 5 acres serves as a home for the Fourniers to raise their two sons in Mount Washington Valley. "It is truly a live, work, love venture and our family puts our whole hearts into creating an incredible restaurant where each patron feels like a welcome guest in our home," Kate said. It's easy to see and feel this as you dine in this wonderful place. Every member of the T.H.E. staff is there to make you feel right at home.
Thompson House Eatery has been a landmark in the Jackson community for almost 40 years. When it closed, Kate and Jeff decided to keep its legacy going, just as the former owners hoped. Everything is made from scratch- pasta, bread, pastries and ice cream! Jeff, a nationally established chef, loves to work with local farmers like Pork Hill Farm and Mill Brook Farm to source pigs, lamb and beef for whole animal butchery. They grow their own microgreens, in house, year round. When I ate there for the first time, the mushroom risotto was made with mushrooms foraged that afternoon in the nearby woods. It doesn't get much fresher than that!
When you visit Jackson, New Hampshire, the Thompson House Eatery is a must. After a two week vacation, they will reopen on Wednesday May 9th and are also open for Mother's Day this coming weekend. Call ahead or reserve online to grab a spot!
Tommy J making a delicious cocktail!
Daily family meal with the whole staff before the restaurant opens.
I can't say enough about this place - you just have to check it out for yourself. Thank you Kate and Jeff Fournier for letting me capture your restaurant and for the delicious food. Thank you Meghan for making this all happen and for the hospitality!


One of the most common questions I get about Jounce is how to handle transitions, since the ContentControl immediately swaps out content. There are some third-party solutions, such as the TransitioningContentControl from the Silverlight toolkit, but Jounce can also handle this right out of the box.
View example in a new window.
The secret is through what I believe is the appropriate use of the Visual State Manager and a Jounce helper that was recently added, the Visual State Aggregator. To demonstrate how transitions work, I created a sample project in the Jounce quick start called VSMAggregator. You can download the source to view the example here (simply choose the download link in the upper right for the latest version).
Before we fully dive into why I chose to use the Visual State Manager explicitly within Jounce, you must understand the "states and parts" model present in Silverlight. An excellent series on understanding the model can be found here.
In essence, Silverlight provides for a "lookless" model using parts and states. Lookless allows you to define a control that has a very specific purpose, yet allow the user quite a bit of room in customizing how it looks and behaves. This is because you don't define the full UI for the control. Instead, you define the parts of the control (the surface of a button, the "thumb" on a scroll bar, the background of a slider) and allow the user to template them. Then, you define the possible states of the control and give the user the ability to respond to a state by changing colors or animating properties.
This is a very powerful system and allows much of the design work to be completely offloaded to the design team while the developer can focus on development. As a developer, the main thing you need to know is that you can go into a state. Controls can have different groups that represent different aspects of states, but we'll keep it simple for now. Assume we have a group called "NavigationStates" and we know we can either be in a "HideState" or a "ShowState."
The Visual State Manager (VSM) provides an attached property called VisualStateGroups for defining states. When you are creating a custom control, there are precise areas where you can define the states for the parts of your template. Likewise, if you are customizing a templated control, the template supplies all of the states and you simply have the task of deciding what they do.
What happens in a UserControl that doesn't technically have parts? This is where it gets interesting. You can only change the state of an element that inherits from Control. However, defining your visual states at the UserControl level may have unexpected results because you are not able to reference the elements that are contained within the root visual. Fortunately, if you define the visual states groups in the root visual for the UserControl, even though the attached property exists at the level of an element that may not inherit from Control, those states will still be available to the parent control.
This means that typically you will define the visual states for a UserControl in whatever you choose as the "LayoutRoot" which in most cases will be a Grid. The only caveat is that when you programmatically manipulate states, you must climb the visual tree to the nearest Control element to choose as a target for your state changes. More on that in a bit.
States are storyboards, pure and simple. As long as you think of states that way, you should have no problem grasping the significance. If you aren't already aware of the hierarchy used by Silverlight to evaluate dependency properties, I suggest you hurry up and read about Dependency Property Value Precedence. Basically, the VSM uses storyboards to coerce dependency properties into a different value.
It can sometimes get confusing when you are defining a visual state because you have two parts to work with: a state (required) and a transition (optional). These are actually two different storyboards that operate against the target control. What's even more confusing is that a "state" is supposed to be the fixed value of the control but you can supply a duration and animate a state! What?
Don't do it! Just because you can doesn't mean you should.
One: States are zero-duration storyboards that represent exactly how your control should look when it is in that state.
In the example, our RedView defines three states. A "hidden state," a "shown state" and a special state it goes into when a slide-in is chosen. To begin with, we simply define exactly how we want it to look in the given state.
The collapsed state only concerns itself with one thing: being collapsed. The visible state ensures it is both visible and hit test visible so the surface is clickable. In the special state with the green slide-in, the control is visible and rotated in a plane projection. It also is not hit test visible, so the "sideways buttons" can't be clicked. Notice that all of the storyboards have a duration of 0. This is the precise set of values we want imposed on our visual when the control is in different states.
Two: Transitions can animate whatever you like, but they should always end up in the same state as the state definition being transitioned to.
Transitions provide quite a bit of flexibility. What's important to understand when dealing with states, however, is that there are two ways to programmatically drive states in Silverlight. You can go to the state with transitions, or without. In all cases, Silverlight will fire the state animation. In the case of transitions, it will fire the transition animation, and then immediately fire the state animation after the transition storyboard completes. The VSM leaves the state storyboard playing after the transition is complete, but will stop the transition storyboard.
If the states and transitions don't match, your control will be left in an unknown state - especially if code has the flexibility to use transitions (or not). Further, if a property is left in a different state by the state animation than the transition animation, only one storyboard can "win" so you always want the animations to conclude on the properties you desire.
The easiest way to make a transition work is to simply specify the states you are transitioning from and to, and provide a generated duration. The visual state manager will modify the storyboard in the state definition to last for the duration, and smoothly animate the properties.
If you want to manipulate other factors, such as a projection, or have key frames, then you must use the transitions. If you are using transitions that don't overlap the state, those animations will stop after the transition is complete and there will be no conflict. Animations that overlap the existing properties in the state storyboard should end with the same values to avoid any conflicts.
Notice that the animations start by setting the control to visible. This is because of the order I mentioned earlier: the transitions fire, then the states. Therefore, if you want to animate a panel into view, you need to make it visible first in case it was collapsed before, or your animation simply won't be visible. The animations may perform different effects but they should leave the control in the "target" state we are looking for. The end result is that changing states with or without transitions should end up with the same result - again, you can easily mess this up so it's important to keep in mind.
As you can see, when the "NavigateGreen" event is raised, the control goes to the "GreenState." Likewise, a "NavigateRed" (the view itself) goes to the "ShowState" and a "NavigateBlue" (a different view) goes to the "HideState."
To demonstrate the difference between manipulating views and actually navigating, the RedView updates a date on the screen. You'll notice when you navigate to the BlueView and back, the date changes. When you navigate to the green slide-in and back, the date does not. This is because the green slide-in is simply a visual state transition, while the BlueView is both a transition and an actual navigation event.
Obviously, having multiple screens or dynamically loaded ones will prevent you from wiring every possibility in the XAML. When Jounce wires a view to a view model, it sets a delegate that allows you to raise state changes (and automatically marshalls them to the UI threads). This allows view models to handle states. In fact, the generic IViewModel interface supports the visual state methods. Typically, a controller will handle navigation through wizards and selections, and raise the navigation events as described in previous Jounce posts. The view model can then transition to the correct state when the _Active method is called. Because view models may have multiple views, the view tag is passed in _Activate and the state transition can be targetted to that view. This allows Jounce to manipulate states from the view model only knowing what the name of the state and optionally the tag of the view is, without having a direct reference to the view or any view artifacts.
Notice that when the view model is initialized, it goes into a default hidden state and does not use transitions. Initialize is always called before activate. Once activated, it logs the activation and goes to the "ShowState." The button for the RedView fires a command that changes the state of the BlueView, publishes the event for the red navigation that the visual state aggregator listens to, and finally navigates to the RedView.
In Silverlight 4 you can tap into events and transitions and inspect the various states. You can even get to the storyboards associated with states. Because states are actual storyboards, you can do things like attach behaviors or programmatically access the storyboards and manipulate them to do things like accommodate the current screen resolution or compute complex animations.
The code grabs the group called NavigationStates, hooks into the state change event, and then uses a message box to publish the transition. To see how to dive even deeper and access storyboards, read Page Brooks' excellent article Finding a Storyboard in the Visual state Manager.
Notice this is a region that views can be routed to. It allows the views to stack on top of each other, and then transition in and out based on the visual states. In Jounce by default, all views are tracked and simply activate or deactivate. The main difference between a ContentControl and an ItemsControl is that in one, the view is completely removed, and in the other, it is collapsed. So what does this look like? The views will remain in the items control but in their collapsed state have no impact on the visual tree. I've used this method with dozens of views and have not noticed any significant, negative impact as the "hidden" views are truly collapsed. Obviously if you are using transient views, then a different strategy such as a TransitioningContentControl should be used instead.

Abdelaziz Bouraoui (), né le  à Sfax et décédé le  à Tunis, est un syndicaliste tunisien.

Biographie
Il étudie au kouttab, à l'école primaire publique puis dans un lycée public de sa ville natale de Sfax. Après avoir obtenu un diplôme d'infirmier, il entre dans le monde professionnel en 1942 après le décès de son père : il travaille à l'hôpital régional de Sfax où il fait la connaissance du syndicaliste Farhat Hached.

Syndicaliste
Il participe en mars 1944 au congrès régional de la Confédération générale du travail (CGT) qui est dominée par les communistes. Hached ne réussissant pas à prendre sa tête, il se retire de la CGT avec plusieurs camarades dont Abdelaziz Bouraoui et Habib Achour.

En , ce groupe participe à la fondation de l'Union des syndicats indépendants du Sud puis de l'Union générale tunisienne du travail (UGTT) dont le congrès fondateur a lieu le . Il y reste dirigeant jusqu'à son arrestation en 1952 pour cause de sabotage. Il est finalement libéré en 1955 et revient à la direction du syndicat.

Toutefois, il se retire à deux reprises. En 1956, obéissant aux ordres du Néo-Destour, le parti au pouvoir, il contribue à la fondation de l'Union tunisienne du travail avec d'autres syndicalistes néo-destouriens dont Achour. Cependant, la fusion des deux syndicats aboutit rapidement et Bouraoui revient à nouveau à la direction de l'UGTT en 1957.

Il est limogé en novembre 1983 avec six autres leaders du bureau exécutif. Il fonde alors un nouveau syndicat baptisé Union nationale tunisienne du travail qui existe jusqu'en 1987, date d'un congrès de rassemblement ; il revient alors à la direction de l'UGTT dont il s'éloigne définitivement en 1988.

Responsabilités politiques
Membre du Néo-Destour, il y reste fidèle toute sa vie. Il y occupe des responsabilités de second ordre, parmi lesquelles celles de délégué du parti à Gafsa, de 1958 à 1960, avant d'être transféré au même poste à Tunis. Son niveau scolaire modeste pourrait avoir été un frein dans son ascension politique.

In Seattle, the successful forensic psychiatrist and college professor Jack Gramm is in evidence since he was responsible for the condemnation of the serial killer Jon Forster, influencing the jury to sentence him to the death row. Jon accuses Jack of manipulation, inducing one witness and sister of one of his victims to testify against him. On the eve of Jon's execution, Jack receives a phone call telling him that he has only eighty-eight minutes of life, while a killer is copycatting Jon, killing women with the same "modus-operandi" and is investigated by Seattle Slayer Task Force. With the support of associate Shelly Barnes, an FBI agent, his friend Frank Parks, and his assistant Kim Cummings, Jack investigates some weird and problematic students, a security guard of the campus and the woman with whom he had one night stand.

Skeletal muscle provides inspiration on how to achieve reversible, macroscopic, anisotropic motion in soft materials. Here we report on the bottom-up design of macroscopic tubes that exhibit anisotropic actuation driven by a thermal stimulus. The tube is built from a hydrogel in which extremely long supramolecular nanofibers are aligned using weak shear forces, followed by radial growth of thermoresponsive polymers from their surfaces. The hierarchically ordered tube exhibits reversible anisotropic actuation with changes in temperature, with much greater contraction perpendicular to the direction of nanofiber alignment. We identify two critical factors for the anisotropic actuation, macroscopic alignment of the supramolecular scaffold and its covalent bonding to polymer chains. Using finite element analysis and molecular calculations, we conclude polymer chain confinement and mechanical reinforcement by rigid supramolecular nanofibers are responsible for the anisotropic actuation. The work reported suggests strategies to create soft active matter with molecularly encoded capacity to perform complex tasks.

Today, MNF Group announced the expansion of its global TNZI operation by opening a new Point of Presence (PoP) facility in Hong Kong. The company claims that the new PoP makes TNZI a carrier of choice for European and US telcos seeking to expand in the APAC region.
Several of the largest global telecommunication corporations are already set to take advantage of the Group's Hong Kong PoP facility, including PCCW Global, SoftBank Corp, M800 and NTT Communications.
The company claims that emerging new-generation call providers in the region will also benefit from MNF Group's specialized voice capabilities, enabling them to deliver additional features and value for their end-users.
Our investment in this new Hong Kong PoP will allow us to compete more effectively for a larger share of the enormous Asian market and ensure our global voice network is able to carry the growing volume of traffic on direct routes between Asia, Europe, the Americas and ANZ.
