One of the recent themes here has been the topic of iPhone OS web apps — apps for the iPhone and iPod Touch that are built with nothing more than HTML, CSS, and JavaScript. And specifically, the issues of how good an experience iPhone web apps can offer, and how easy they are to develop, compared to native Cocoa Touch apps.

One area in particular where iPhone web apps fall short of native iPhone apps is scrolling. Take for example a long list, such as your full address book in Contacts, or all your songs in the iPod app. When you scroll these lists, you can fling the list, and the list will scroll at high speed after you let go. The effect is sort of like spinning a wheel with very little friction. With iPhone web apps, you can make a list that looks almost, maybe even exactly, like a native iPhone list view. But all web views on the iPhone scroll with almost no momentum. You can’t fling them. iPhone web views feel like they have a lot of scrolling friction.

This friction might make sense for regular web pages rendered on the iPhone’s small screen, where by “regular” I mean “not optimized specifically for display on the iPhone”. But it just feels slow — stuck — on iPhone-optimized apps.

If you’ve never taken notice of it, try it now, comparing something like your Contacts app list with an iPhone web app like Showtime. (In Showtime, tap “Watchlist” and then tap the “+” button to get a nice long list to scroll through.) Another good scrolling comparison: native iPhone Twitter clients like Tweetie and Birdfeed versus iPhone web app Twitter clients like Hahlo and the new Mobile Twitter. The difference is significant, and far more than cosmetic. As Justin Williams recently wrote:

I believe that with the current crop of Web technologies available in MobileSafari, apps like Hahlo, PocketTweets and Showtime could thrive as an alternative to their native counterparts if Apple allowed developers to adjust the scrolling/drag coefficient of Mobile WebKit. If you compare the scrolling speed of your Twitter timeline in Hahlo and Tweetie, the results are drastically different. Tweetie feels like it effortlessly scrolls based on how much momentum you exert in the scroll action, while Hahlo is being constrained by a fifty pound weight on its back.

Scrolling isn’t the only UI/experience issue where web apps seemingly can’t quite match what native iPhone apps can offer. Another is that MobileSafari doesn’t allow for CSS fixed-position elements, which means you can’t make a toolbar that stays put at the very top or bottom of the screen without having it scroll away when you scroll the content.

And that’s just talking about the user experience side of things. The other side is that of development. Last month I wrote:

When you write a Cocoa Touch app for the iPhone, you’re not starting from scratch. You’re starting with the Cocoa Touch framework. As Faruk Ateş astutely points out in his response to Koch, to discount the framework is to discount everything that sets the iPhone apart as a development platform. Not only are native iPhone apps faster and more capable than their web-app equivalents, but they’re easier to write.

Some readers objected to this, arguing, more or less, that no matter how good the Cocoa Touch framework is, native iPhone apps are harder to develop than web apps because one must learn both the app framework (Cocoa) and a new programming language, Objective-C. But that’s not really a fair comparison. It’s like saying it’s easier to run than to bike if you don’t know how to ride a bicycle.

Let’s clarify. Let’s specify that we’re talking about creating iPhone apps with great design and user experiences. Let’s acknowledge that to make anything great — anything at all, software or otherwise — one needs talent, experience, and familiarity and expertise with the necessary tools. If you’re already an expert web developer but have never programmed Cocoa software, then yes, there’s large time-consuming Step Zero in front of you before you can attempt to develop a native iPhone Cocoa Touch app. But, likewise, there are long-time Cocoa Mac (and a handful of even longer-time NeXT) developers who have no idea how to create a modern AJAX-y web app from HTML, CSS, and JavaScript — and who think JavaScript is the weird programming language.

What I’m saying is that talented Cocoa Touch developers have an easier job implementing the same iPhone app than talented web app developers do. The Cocoa Touch framework makes all sort of things free or easy. Things like smooth fast animation between views. Things like buttons and lists and toolbars that look just like other standard iPhone buttons, lists, and toolbars.

There do exist some open source frameworks for iPhone web app developers, so that one need not start from scratch implementing things to mimic Cocoa Touch UI elements. iUI, started by Joe Hewitt just a few weeks after the original iPhone debuted in July 2007, is one. jQTouch, by David Kaneda and based on jQuery, is another. (Showtime is built using jQTouch.)

But these frameworks don’t solve the problem with scrolling speed/friction, or fixed-position elements.

It ends up there is a company, however, that has developed an amazing iPhone web app framework which:

• Completely hides the address bar, even when running not from a saved-to-the-home app icon, but within a page in MobileSafari itself.

• Allows for fixed-position toolbars that never budge from the top when you scroll.

• And: sets its own scrolling friction coefficient, allowing you to fling long lists.

The company behind this web framework is Apple. And the framework is apparently named PastryKit.

The Best iPhone Web App in the World

If you have an iPhone or iPod Touch handy, stop reading this and go here:

http://help.apple.com/iphone/3/mobile/

This is not a secret web site. In fact, it may well already be in your iPhone bookmarks — it’s where you get redirected when you choose the “iPhone User Guide” bookmark that’s included as one of the defaults for MobileSafari. I don’t know when Apple launched this PastryKit-powered version of the site, but it’s been under our noses for a while, with very little notice.1

If you don’t have an iPhone or iPod Touch handy, or if you do and you’re back after trying it out and want to poke at it with Safari’s Web Inspector, you can also load it in Mac or Windows Safari by setting the user agent string to MobileSafari 3.x in Safari’s Develop menu. (Without the MobileSafari user agent string, you’ll get redirected to a different iPhone help page; using a MobileSafari 2.x user agent string, you’ll see last year’s version of the User Guide, which is far less impressive technically.) Shrink your Safari window down to roughly iPhone dimensions before loading the site, because the UI will be laid out to fill the dimensions of the viewport when it loads.

The JavaScript source code has been minimized/optimized, but it’s not obfuscated, per se, so it’s easy to see that the framework is called PastryKit, and even a dilettante JavaScript hacker like me can follow along and see some of what’s going on. PastryKit accomplishes all three of the aforementioned things — hiding the MobileSafari address bar, providing fixed-position toolbars, and providing scrolling with momentum — by disabling regular scrolling and setting up its own view hierarchy and implementing its own scrolling.

From WebKit’s perspective, everything in this iPhone User Guide is in a view that is exactly the size of the viewport, so there’s nothing to scroll. PastryKit handles all of what the user sees as scrollable content. This is how on the iPhone it provides for lower-friction scrolling than provided by MobileWebKit itself — PastryKit does its own scrolling math. And it’s even more noticeable when running the app in desktop Safari with the user agent trick, because you never see Mac scrollbars, and can’t use your mouse scrollwheel to scroll the content. Everything related to scrolling is implemented within the app itself, in JavaScript.

After installing the User Guide app to your home screen and launching it from there, there’s really very little to suggest that it isn’t a native iPhone application. No MobileSafari address bar at the top, no MobileSafari toolbar at the bottom. Scrolling is fast and has momentum. It even works perfectly offline, because the contents of the user guide are stored locally in a database using HTML5.

It’s not perfect. Scrolling is smooth on my iPhone 3GS, but it’s a little janky on my old iPhone 3G and original iPhone. (Still better than the scrolling in any other web app I’ve ever seen, though — just not native-app-smooth.) Taps and gestures sometimes don’t register — this is most noticeable for me when I try to scroll as fast as I can with a quick finger swipe. Super-quick gestures, I suspect, sometimes slip through the JavaScript event filters.

The rubber-band “bounce” scrolling — where if the view is already at the top but you pull down in an attempt to scroll up and you see whitespace and it all just bounces back into place when you let go — breaks if you pull down all the way off the bottom of the display. What happens there is the view gets “stuck” in the position where it’s displaying the stretched-out whitespace at the top of the view; you can unstick it by just tapping somewhere in the content area.

And, lastly, it doesn’t work at all with the iPhone’s system-standard gesture where you can tap the status bar at the top of the screen (the bar that displays the carrier name, signal strength, time, and battery life) to scroll to the top. In MobileSafari, if you tap the status bar while running this app, the entire MobileSafari view scrolls to the top, which exposes the browser address bar. When running the User Guide app from the home screen, tapping the status bar simply has no effect. I presume the problem here is that there is no JavaScript event in mobile WebKit for status bar taps — the event goes to the iPhone app, and the web app running in WebKit inside the iPhone app can’t see it or register a handler to act upon it. From a user’s perspective, an iPhone web app launched from the home screen is just another app. But technically, it’s like a meta app — it’s a JavaScript app running inside a native iPhone app that just presents a full-screen WebKit view and loads the web app.

But on the whole this User Guide app and the PastryKit framework are rather amazing. The $64,000 question, though, is whether PastryKit is something Apple intends (or that a team within Apple hopes) to ship publicly. It seems like a lot of effort to build a framework this rich just for this iPhone User Guide, so I’m hopeful the answer is yes. Perhaps something integrated with the next major release of Dashcode? And, perhaps with integrated UI layout tools, along the lines of Interface Builder?

Here’s to hoping we haven’t heard the last of PastryKit, and that Apple continues work on making mobile WebKit an open alternative to the App Store.

PastryKit / iPhone User Guide Demos

For the sake of posterity and for those of you without access to an iPhone or Safari, I’ve made two screencasts showing the iPhone User Guide web app in action.

1. There’s a question on Stack Overflow from October 22 asking about PastryKit, and jQTouch developer David Kaneda has mentioned it a few times on Twitter, but those are the only references to it I’ve been able to find. ↩

So I’ve been breaking my pidgin IRC habit lately with irssi, and its going pretty well. I’ve been using it for about a week now, and there are a few settings and mods that have been pretty helpful in making it my client of choice.

The Hilight Window

So I’ll be honest, I’m not all that great at scrolling back through the logs that pile up when I’m away, and more specifically, oftentimes I don’t care about what was said, unless its addressed to me, or something that I’m concerned about. This is where the “hilight window comes in handy. Grab this perl script (highlightwin.pl) and put it in your ~/.irssi/scripts/autorun directory. then fire up irssi and run these commands to activate

/run autorun/hilightwin.pl
/window new split
/window name hilight
/window size 6
/hilight <your nick>

After doing all that, you’ll see a window like the one to the left. Any time your name is mentioned, that message will go to that window, along with the room it was mentioned in. Furthermore if you’re interested in things TheoreticalBob says, or any time ‘ffmpeg’ is mentioned, you can just do /hilight TheoreticalBobNow or /hilight ffmpeg respectively. Now you won’t miss messages if you’re chilling in #roomA and you’re needed in #roomB!

Hiding joins/parts

These messages are annoying to me. Personally, I dont care when someone enters or leaves the room, I just care if they’re there at that particular moment. I can look at the currently-present list if I want to talk to someone specific. Join/part messages can also fill up the valuable terminal space you have with information you simply dont care about. Turn off all Join/part/nick change messages with:

/ignore -channels #roomA,#roomB,#etc * JOINS PARTS QUITS NICKS

Screen

This is the primary reason I wanted to run irssi. With pidgin, I’d often leave one computer connected, and have like 4 nicks signed on at once. kdub, kdubois, and kdub_ all get pretty annoying to the other people in the room. If you run ’screen’ you get a terminal that ‘runs in the background’ even when you close the window. You can quit the window, or hit ctrl-a-d to disconnect from the screen session. The sweet part is that irssi is still running in the background, collecting messages, and maintaining your IRC connection. You can reconnect with ’screen -raAd’. This is pretty cool because you can run irssi on one computer, and connect to it from anywhere in the world over ssh. If my desktop is running irssi, i can connect back to my irssi session by ssh-ing in and running the screen command! Pretty handy…

Save

Don’t forget to save your settings with the /save command! this tripped me up for a bit

I’m still tweaking irssi, and if any of you have any hints or tricks that you can’t live without, I would be eager to hear them!

En un artículo anterior os expliqué en qué consistía la filosofía Strobist y cuales eran los componentes básicos necesarios para iniciarte en la iluminación portátil. En este artículo te explico cómo conseguir tu equipo más básico por muy poco dinero. Por tan solo 80 euros he conseguido juntar mi equipo básico de iluminación, flash incluído. ¿No te lo crees? En este artículo te cuento cómo conseguir cada uno de los elementos del equipo. Verás como al final salen las cuentas.

Introducción Aunque he ido ampliando mi equipo con el tiempo, hoy he querido hacer el ejercicio de reunir los enlaces necesarios para reunir un equipo strobist básico. Como casi siempre, para estas cosas recurro a eBay. Al final es la forma más cómoda que tengo de conseguir material de lo más diverso sin moverme de casa.

Y como de vez en cuando algún amigo me pregunta sobre ideas para regalar a algún amante de la fotografía y me acaba tocando encargarlo a mí, me he decidido a hacer la recopilación para tenerlo a punto si me llega la oportunidad. Y como he hecho otras veces, quería compartirlo contigo.

Todos los artículos encontrados están en la modalidad "Compralo Ya" (el precio mostrado es el final, no se trata de subastas).

Como los productos tienen una duración finita, los enlaces apuntan a las correspondientes búsquedas en eBay. Dependiendo de la cotización del dolar y de las ofertas de los vendedores los precios fluctuarán al alza o a la baja. No olvides marcar la opción "Todo el mundo" en tus búsquedas y ordenar los resultados por "Precio + envío: más bajo primero".

1) Lo primero, el flash

Si ya contáis con un flash os podéis ahorrar este paso (y una buena parte del presupuesto dedicado al equipo de iluminación).

Como vamos a disparar el flash remotamente, no es necesario disponer de un flash TTL, pero si es necesario que tenga la posibilidad de regular la potencia.

En mi caso opté por un Yongnuo YN460, de lo más barato que pude encontrar en el mercado. Lo conseguí nuevo por poco más de 40 euros gastos de envío incluídos, y acabo de ver que se puede conseguir ya por poco más de 30 euros.

En éste artículo te hablo en detalle del flash, donde además hay muchas opiniones y experiencias de usuarios que optaron por uno igual.

2) El trípode para el flash (Light Stand)

De nuevo, eBay es mi referencia. Hay que rebuscar un poco para encontrar lo que uno busca, porque se utiliza un término un tanto genérico para describirlo que coincide con otros productos más baratos. Puedes probar con "studio light stand".

En el momento de escribir estas líneas Next Digital tenía en stock un trípode de 180 cm como el mío por 21 euros gastos de envío incluídos. Un auténtico chollo. Y en Gadget Infinity los tienes por 24, más pequeños, eso si.

3) El soporte para la sombrilla

El soporte para la sombrilla (no se si existe un mejor nombre en español) es la pieza que se fija a la punta del trípode, sosteniendo la sombrilla y a la que se engancha el flash.

Tiene muchos nombres, pero los he podido encontrar muy baratos buscando "Flash Shoe Umbrella Holder Swivel Light Stand Bracket". Tan baratos como que cuestan otros 6 euros.

4) La sombrilla translúcida

La última pieza para montar el flash en el trípode es la sombrilla. Se trata de una sombrilla blanca (translúcida) que permite disparar el flash hacia el objeto y actua a modo de ventana de luz, ampliando la fuente de luz a la vez que la difumina.

Se puede encontrar por tan solo 5 euros con los gastos de envío incluídos, y si te fijas bien, hay vendedores que venden la sombrilla junto con el soporte, con lo que puede que consigas un mayor ahorro.

5) El disparador inalámbrico

Podría haberme ahorrado este elemento para que me saliera más barato el kit, pero creo que es un complemento fundamental.

En su momento adquirí un juego de emisor y receptor PT-04, pero posteriormente ha salido una evolución, el CTR-301, que me parece que cuenta con varias mejoras en su diseño, aunque se necesita un pequeño adaptador para engancharlo al soporte de la sombrilla, ya que por defecto viene con una rosca de trípode.

El PT-04 se puede encontrar por apenas 13 euros y el CTR-301 se puede encontrar por menos de 18 euros en kit de receptor y disparador.

Así que, todo el equipo por tan solo 80 euros

Si no has hecho aún la suma, te ayudaré:

32 euros del flash, 21 del trípode, 6 del adaptador, 5 de la sombrilla y 13 del disparador remoto son exactamente 77 euros. Teniendo en cuenta que siempre que pago por PayPal me acaban subiendo un poco el tipo de cambio, seguro que se queda en los 80.

Parece increíble, ¿verdad? ¿A que al principio no te lo habías creído?

The easiest way to get started with VIX is by using the vmrun command which is packaged inside of VIX. It's a command-line executable that doesn't require a development environment, and is pretty easy to use once you get the hang of it.

Since I mostly use ESX, I want to take an ESX-centric view of using vmrun in this post, and I'm also going to focus on what you can do to the guest operating system within VMs. Specifically I'm going to address two use cases that I think are pretty important and useful:

1. Installing an agent within a VM.
2. Restarting a service on a Windows VM.

First, you'll need to install VIX 1.6.2. On Windows you'll find vmrun in %PROGRAMFILES%\VMware\VMware VIX. On Linux it should be available in your path, so you can just run it from anywhere. Next, make sure you've got an ESX 3.5 update 2 or higher server to run commands against. In addition, you'll need a VM whose operating system is running an up-to-date copy of VMware tools.

If you type vmrun with no arguments you'll get a listing of all the things vmrun can do, but I want to focus on guest operations, which are listed below.

Table 1: Guest operations supported by vmrun.

Operation	Description	Supported on ESX?
runProgramInGuest	Run a program in Guest OS	Yes
fileExistsInGuest	Check if a file exists in Guest OS	Yes
setSharedFolderState	Modify a Host-Guest shared folder	No
addSharedFolder	Add a Host-Guest shared folder	No
removeSharedFolder	Remove a Host-Guest shared folder	No
listProcessesInGuest	List running processes in Guest OS	Yes
killProcessInGuest	Kill a process in Guest OS	Yes
runScriptInGuest	Run a script in Guest OS	Yes
deleteFileInGuest	Delete a file in Guest OS	Yes
createDirectoryInGuest	Create a directory in Guest OS	Yes
deleteDirectoryInGuest	Delete a directory in Guest OS	Yes
listDirectoryInGuest	List a directory in Guest OS	Yes
copyFileFromHostToGuest	Copy a file from host OS to guest OS	Yes
copyFileFromGuestToHost	Copy a file from guest OS to host OS	Yes
renameFileInGuest	Rename a file in Guest OS	Yes
captureScreen	Capture the screen of the VM to a local file	No
writeVariable	Write a variable in the VM state	No
readVariable	Read a variable in the VM state	No

Use case: Installing an agent in your VM.

Installing agents is an integral part of managing large numbers of systems, whether physical or virtual. Usually you want to bake your agents into your OS image, but occasionally a new agent will come along that needs to be deployed to existing systems. This example shows how you can copy an agent from your desktop to your VM and install it. The only thing you need is an agent that can be installed without user intervention (which is the norm for agents anyway).

Please note: Commands should be entered all on one line, it's split up here just for the sake if fitting it into the blog.

Example 1: Copying an MSI file from your desktop to your VM.

vmrun -T esx -h https://esx.example.com/sdk

-u root -p secretpw -gu user -gp userpw

copyFileFromHostToGuest "[storage1] Windows/Windows.vmx"

"c:\program files\my agent software\agent.msi" c:\agent.msi

One thing to point out here is that, despite the command saying "From Host to Guest" the file is actually being copied from the same system where vmrun is invoked (for example your laptop or workstation).

Next we use runProgramInGuest to install the MSI.

Example 2: Invoke the MSI file we copied above.

vmrun -T esx -h https://esx.example.com/sdk

-u root -p secretpw -gu user -gp userpw

runProgramInGuest "[storage1] Windows/Windows.vmx"

c:\agent.msi

Use case: Restarting a service on Windows.

This one's really easy so I'll just show it without explanation.

Example 3: Restart a service on Windows.

vmrun -T esx -h https://esx.example.com/sdk

-u root -p secretpw -gu user -gp userpw

runProgramInGuest "[storage1] Windows/Windows.vmx"

c:\windows\system32\net.exe restart dhcp

If Linux is more your style, tweak the last part to say something like /etc/init.d/sshd restart and you'll be restarting Linux services just as easily.

How do I get the path to my VMX file?

The hardest part about dealing with vmrun when you're managing ESX is knowing where your VMX file is. To get this you have to either log in to your ESX system and locate the VMX file, or you can use the VI API. Within the VI API, the VirtualMachine object contains a data structure called VirtualMachineFileInfo. The vmPathName property of this structure tells you the path to your VMX file. Not very pretty, but over time you'll see us rolling out some more convenient ways to access the functionality VIX provides. In the meantime there's a lot of really useful stuff you can do with tools like vmrun.

NOTA: Este post está realizado usando un álbum que la gente de Snappy Book me mandó de manera gratuita para que les diera mi opinión, lo dejo claro para evitar posibles problemas. No me pidieron que lo publicase en el blog, pero soy usuario habitual de esta marca, ya hice una review en Abril de 2007 En este caso como no tenía ningún álbum en menté pensé en regalárselo a Maria Figueiras, mi maquilladora habitual por la paciencia que tiene en las sesiones y su buen trabajo. Como no tenía demasiado tiempo libre este álbum está hecho usando la versión Express del software de Snappy Book, en esta versión eliges plantillas, eliges carpeta con fotos y el software monta todo el álbum de manera automática en menos de 1 minuto!. Luego cambié un par de fotos de sitio, cambié la portada y tenía el álbum preparado para enviar en menos de 5 minutos. Alguno me pidió un screencast de como funciona esto, espero poder hacerlo pronto. 

El nombre de el álbum es Snappy Print 21X28 cm
Podéis ver todas las fotos en grande pinchando sobre ellas

Bueno, a lo que íbamos, al igual que el álbum fotográfico que revisé hace unos días, el álbum viene perfectamente empaquetado en una caja de madera, así se evita que las esquinas lleguen dañadas.
En este caso nos encontramos una sorpresa que el álbum de calidad fotográfica no tenía ( y que digo yo que por lo que cuesta podría traer) y es una bolsa de tela con el tamaño perfecto para llevar nuestro libro. Puede parecer un detalle algo superfluo pero a mi me ha gustado, sobre todo porque lo regalé con la bolsa y parece que "viste" mas ¿no?

También nos vien un punto de lectura con la url de la web de Snappy, nada excitante y con una utilidad muy relativa en un álbum de fotos.
 

La calidad de la portada es exactamente igual a la de los álbumes fotográficos, transmitiendo una gran solidez, sin duda un acabado de buena calidad. La posibilidad de personalizar la portada al máximo es de agradecer. La sobriedad en el acabado también.

Como ya he comentado he utilizado plantillas propias del soft y he dejado que este coloque las fotos de manera automática, aquí podéis ver ejemplos de como ha terminado. En este caso usé un acabado "moda" encajando bien con la temática de las fotos, pero hay plantillas de vacaciones, niños, viajes�?�

Las páginas pueden abrir 180º sin ningún tipo de problema permitiendo ver las fotografías a doble página con todo el esplendor que se merecen�?�

Aquí podéis ver una comparación del álbum offset (arriba) frente a uno fotográfico de la misma marca (abajo). General y detalle

COMPARACI�?N CON ÁLBUM OFFSET DE HOFMANN

Voy a hacer una pequeña comparación de tamaños, acabados, calidades�?� de este álbum de Snappy frente al equivalente de Hoffman.
Para  empezar la portada, la de Hoffman es brillante y acolchada, frente a la algo mas mate y dura de Snappy. ¿Cúal es mejor? para gustos los colores, a mi los acolchados no me terminan de convencer pero suelen gustar mucho a los profanos en esto A mi me gusta mas la terminación del segundo, pero repito, es una opinión personal, en casa cuando viene alguien les impresiona mas la portada del Hoffman.

Como podéis ver de tamaño son bastante parecidos, el de Snappy es ligeramente más grande (21 X 28 cm) , tanto en alto como en ancho, pero no demasiado. En estas fotos no os fijéis demasiado en el de Hoffman, un día se me cayó al sueo y anda con ese "bollo" culpa mía.

De lomo y cosido son parecidos, aunque el sistema de Snappy parece algo mas resinstente a aperturas completas del álbum, pero ya os diré cuando lleve unos meses de "uso" a ver si aguanta bien, el Hoffman tiene ya mas de 2 años.

Calidad de las fotos, que es lo que nos importa, ¿no? El acabado de Snappy es algo menos brillante que el Hoffman, parece que el Hoffman tenga una lámina protectora brillante por encima de la fotos (en algún caso, en alguna esquina está un pelín tocado) No se como afectará todo esto a la durabilidad porque no tengo ningún álbum de este tipo de mas de 3 años (Hoffman) y no parece que hayan perdido mucha calidad, ya veremos dentro de 50 años (Recordérmelo)

El revelado Offset, que es el de esto álbumes se realiza en impresoras especiales que abaratan costes respecto a un revelado químico "tradicional". En las siguientes fotos podéis ver fotos macros de 3 tipos de álbumes: el primero es un Hoffman Offset, el segundo un Snappy Offset y el tercero es un Snappy de la serie fotográfica.

Se aprecia una trama algo mayor en el primer caso que en el segundo (en el tercero no hay trama visible y se nota que es revelado químico).

Pero ¿Cómo se traduce a la vista? ¿Se nota demasiado? Pues hay que hilar muy fino para encontrar diferencias si uno no es muy observador y perfeccionista, yo sigo con los álbumes fotográficos pero es que soy algo "tiquismiquis" con la calidad y si puedo siempre voy al mejor acabado.
¿Se nota diferencia entre los dos offset? Pues un poco, la verdad, la trama en el primero puede ser muy evidente en algunos casos, sobre todo en fotografías pequeñas. Aunque ya os digo que debe de ser un tema muy sutil porque cuando alguien viene a casa no muestra muchas mas preferencia por uno o por otro.
¿Seguiré haciendo álbumes offset? Pues seguramente, pero solo para temas que no precisen de uan calidad superior, puede ser un álbum idela para guardar fotos más casuales o familiares de uan manera bastante económica (44 �?� y metí mas de 200 fotos)

El precio de un Snappy Print 21�?28 es a partir de 44 �?� siendo 54 �?� el precio máximo si nos decidimos a poner 60 páginas, creo que no está nada mal (y mas, si lo comparamos con los fotográficos de las mismas caracteristicas a  75�?�7175�?� respectivamente)

Espero que os haya gustado la review y si tenéis dudas los comentarios son todos vuestros

There are situations where it is necessary to call a server side method on FMS. Some CDNs, for example Limelight, used to or maybe still do require you to call the FCSubscribe method in order to request a live stream. This send a signals to the Edge server to pull the live stream from the Origin server if it is not already being delivered to that Edge. While this delivery method and stream setup routine is being phased out across most CDNs I thought it may be useful to post a (slightly hackish) workaround to make this setup work with the FLVPlayback component.
The problem with the FLVPlayback component is that there is no obvious, simple way to obtain a reference to the NetConnection Object it uses under the hood. While you can implement a custom NCManager class, this is not trivial and after all a NetConnection is being maintained already by the component, so why reinvent the wheel?

Note that the following code is not something I am proud of, but it worked at the time when I needed it. It was used to get a live stream working with the FLVPlayback component streaming from Limelight about a year ago.

// listen to player events and kill manual connection once we're streaming player.addEventListener("playing", playListener); player.addEventListener("stateChange", stateListener); player.addEventListener("ready", readyListener); /* this is the hack: check once every frame if the NC has been defined inside the FLVPlayback component */ this.onEnterFrame = function() { if (player.ncMgr.getNetConnection() != undefined) { this.onEnterFrame = null; delete this.onEnterFrame; trace("got NC"); //subscribe(streamName); } } var nc:NetConnection; var serverName:String = "server.llnwd.net"; var appName:String = "account_name/_definst_"; var streamName:String = "live"; var source_Str = "rtmp://" + serverName + "/" + appName + "/" + streamName; // start up by setting the contentPath (now called source in newer versions of the component) player.contentPath = source_Str; function subscribe(name:String) { nc = player.ncMgr.getNetConnection(); nc.onFCSubscribe = function(info:Object) { trace("onFCSubscribe: " + info.code); clearInterval(int_id); if (info.code == "NetStream.Play.StreamNotFound") { // handle error, retry after a few secs or similar } else if (info.code == "NetStream.Play.Start") { // we're successfully subscribed } else { // handle error } }; // not used right now nc.onFCUnsubscribe = function(info:Object) { } trace("subscribing to " + name); nc.call("FCSubscribe",null,name); } // can be used to unsubscribe from stream function unsubscribe(name:String) { nc.call("FCUnsubscribe",null,name); } Hopefully this is helpful to someone.

Suikoden fans will be happy to know that the Suikoden VI may soon be a reality. Or at least, it may soon be an actual product as suggested by several recent clues. Clues that point to a new Suikoden possibly being announced at the TGS 2009.

These clues started with Konami registering a US trademark for the name “Genso Suikoden” (which is the Japanese name for the series). After this, Blue Moons Studio, a Japanese company founded by the creator of the Suikoden series (Yoshitaka Murayama) announced that he was working on a new RPG. But didn’t give a name or title for it. Which means it could be a new Suikoden.

Then in an interview, Muryama said that he could consider returning to Konami to make another Suikoden. The last clue is the fact that Konami is planning on announcing no less than five new games at TGS 09. Meaning that one of these could possibly be Suikoden 6.

The series hasn’t been seen in America since Suikoden V was released for the PS2 back in 2006. Although there was a DS title, Suikoden Tierkreis, that released in December of last year, but it was a spin-off and not a core game in the series.

And since Suikoden does have a cult following, there is a chance that Konami may return to it. It’s all rumor for now though. We’ll just have to wait and see. But I’m sure Suikoden fans everywhere have their fingers crossed.

We’re pleased to announce a new feature in Windows Server 2008 R2: RemoteApp User Assignment. The RemoteApp User Assignment feature gives administrators the ability to show a customized list of RemoteApp programs specific to the logged-on user in RD Web Access and RemoteApp and Desktop Connections. This has been one of our most requested features since Terminal Services Web Access (TS Web Access) was released in Windows Server 2008.

Why assign Remote App programs to users?

In Windows Server 2008 TS Web Access, if two users with different application usage patterns log on to the website, they will both see the same list of RemoteApp programs. For example, a user from HR and a developer will see the same set of published applications. They will both have to dig through several published applications to access the ones that are relevant to them.

By using RemoteApp User Assignment, Windows Server 2008 R2 provides a solution to filter the applications based on the logged-on user. By using this new feature, the administrator can easily set up the system so that users will only see the applications they use. In our example scenario, the HR user will only see HR applications, and the developer will only see development applications. This feature makes it easy for users to find and run the applications that are relevant to them.

How it works

The RemoteApp User Assignment feature is implemented by adding an access control list (ACL) to every RemoteApp program. When a user logs on to RD Web Access, the list of applications that are viewable to this user is fetched from the RD Session Host (RDSH) servers. As we can see in the diagram below, when RD Web Access is configured to point directly to one or more RD Session Host servers, RD Web Access directly queries the servers and filters the retrieved list of RemoteApp programs based on the ACLs.

When RD Web Access is configured to point to an RD Connection Broker server, the Connection Broker server queries the RD Session Host servers and filters the list of RemoteApp programs, as shown in the diagram below.

When the RemoteApp program is first published, its default ACL allows all users to see the application. Through UI and Windows PowerShell™, the ACL can be configured to allow only certain domain users or entire domain groups to view the application. See the relevant sections later in this post for detailed configuration steps.

Considerations

There are a few considerations when setting up this feature that I’d like to mention briefly.

1. The RemoteApp programs can only be assigned to domain users or domain groups, not local users or local security groups. If a user logs on to RD Web Access with a non-domain account, all RemoteApp programs will be displayed, as with Windows Server 2008 TS Web Access.

2. The computer that is actually performing the check of the user’s credentials against the RemoteApp program’s ACL (see the diagrams in the previous section) must be either a member of the domain’s Windows Authorization Access Group, or be joined to a domain running in Windows 2000 compatibility mode.

NOTE: RemoteApp User Assignment is not intended to be a security mechanism; rather it is a discoverability mechanism. There are already ways to secure access to an RD Session Host server, and the RemoteApp User Assignment feature does nothing to change or improve upon them. This feature only helps reduce the number of unnecessary applications that are otherwise displayed to users.

RemoteApp User Assignment using UI

In RemoteApp Manager UI, a new tab, User Assignment, has been added to the RemoteApp Properties dialog box:

As you can see in the screenshot, this new tab allows administrators to specify which domain users and groups can view the RemoteApp program in RD Web Access and the RemoteApp and Desktop Connection feed.

To filter the applications, select the Specified domain users and domain groups option, and then click Add or Remove to modify the list of assigned domain users and groups. The screenshot below captures a configuration where the application is configured to be shown only to the members of the domain group RDVSTRESS\testgroup.

RemoteApp User Assignment using the Remote Desktop Services module for Windows PowerShell

The feature can also be managed by using the Remote Desktop Services module for Windows PowerShell:

1. Click Start, click Administrative Tools, and then click Windows PowerShell Modules.

2. To switch to the Remote Desktop Services module for Windows PowerShell, type cd RDS:\.

3. Type cd RDS:\RemoteApp\RemoteAppPrograms and then press ENTER. A dir command at this container lists all the applications that are published.

4. Type cd .\<app>\UserAssignment and then press ENTER. A dir command at this container lists all the users and groups to whom the application is assigned.

5. To assign the application to a user 'testdomain\user2', type New-Item -Path RDS:\RemoteApp\RemoteAppPrograms\<app>\UserAssignment -Name user2@testdomain and then press ENTER.

6. To unassign the application to a user 'testdomain\user2', type Remove-Item -Path 'RDS:\RemoteApp\RemoteAppPrograms\<app>\UserAssignment\user2@testdomain' and then press ENTER.

7. Type dir and then press ENTER to see the user removed from the list of users.

As Hp acquired Neoware several months ago, customers are searching for new thin clients .. and I received a Neoware e90 thin client. What could I do with it ? … hmm, let’s try to use it at home as a small appliance to host a USB HDD that can be shared . Advantage is that it doesn’t consume a lot of electricity (in comparison with my Asus Barebone with a AMD x2 64) and doesn’t produce noise at all .. which is also a good thing. The thin client I received has a Via Nehemiah cpu @ 800mghz and 128Mb ram. It also has a small IDE-DiskOnChip disk (32mb) but that is obviously too small to setup CentOS on it. I decided to dedicate a small 1Gb USB stick gift I received from a “well-known hypervisor” company (aka Vmware) and use it for / and swap.

I disconnected the DiskOnChip module from the motherboard and configured the bios to boot in pxe as first device and local usb-hdd for the second one (if you need a password, it’s likely to be either ‘dogbites’ or ‘DOGBITES’) and i started a CentOS 5.3 setup. But that didn’t work on first try : the embedded NIC (VIA Technologies, Inc. VT6102 [Rhine-II] (rev 74) ) refused to aquire an IP address . Switching to VT3/VT4 showed me that even if via-rhine.ko kernel module was loaded, it was impossible to have a network connection. (message was related to “netdev watchdog transmit timed out” and some IRQ messages too). I then decided to add the kernel parameter ‘irqpoll’ and then the setup was able to work on the network. One problem solved … Second problem is that with 128mb ram, CentOS 5.x normally isn’t installable. Well, if you use text mode (anyway graphical mode will even refuse to start …) and use disk-druid to create the swap partition, anaconda will use it directly to simulate the missing RAM. Other thing is that I *had* to use NFS based setup : I tried http based setup and it always died on me (maybe because it had to fetch stage2.img while with NFS it just loop-mounts it …). Anyway it installed succesfully on the USB stick (minimal install, so every component removed from the software selection, took 29 minutes to complete) and it rebooted normally. Don’t forget also to add the irqpoll kernel parameter in grub.conf so that you’ll have network connection after reboot … And as an image talks more than a long sentence .. :

FAQ | Table of Contents | Definitions

What is this and where do I start?

  Part 3 of 3

This is the last of a three part sub-series on using Entity Frameworks and RIA Data Services to move data from our Sql Server database to our Silverlight Application’s DataGrid.

In Part 2, we explored returning an object graph by using the Entity Frameworks and by decorating the metadata for the RIA Services with the properties we wanted to retrieve from the contained object.

Until now, however, all of our code has instantiated via RIA Services context programmatically, invoked the query function programmatically, and assign the returned collection to the items source property of the data grid programmatically. In this post, I’ll look at a declarative approach.

Using the RIA Services DomainDataSource Control

We’ll begin with the program as we left it after the previous blog post, but we’ll immediately remove the three lines in blogs.xaml.cs that manipulates the data context.

1: public partial class Blogs : Page 2: { 3: // private readonly BlogsContext bc = new BlogsContext(); 4: public Blogs() 5: { 6: InitializeComponent(); 7: // bc.Load( bc.GetBlogsQuery() ); 8: // this.blogsDataGrid.ItemsSource = bc.Blogs; 9: }

 

Having removed the programmatic interface to the data context, let's now open up blogs.xaml  and provide it with information about the data context by way of teh DomainDataSource  control, which we must first add to the toolbox. To do so, right-click on the Silverlight Xaml Controls tab, and then click on Choose Items.

Within the Choose Toolbox Items dialog box click on the Silverlight Components tab, and then click the browse button. Navigate to your program files ->Microsoft SDKs -> RIA Services, pick the folder for the latest version, within that:  Libraries-> Silverlight.  Double-click on System.Windows.RIA Controls.dll 

You should find that the DomainDataSource control has been added to the bottom of your list of controls; you may want to right-click and choose to sort them alphabetically.

Drag a DomainDataSource control onto the Xaml page just above the DataGrid.  By dragging it on rather than writing it yourself Visual Studio will create the namespace for you set up your using statement and your references.

The four attributes you'll typically want to set, if no others, are the Name , LoadSize, QueryName, and the AutoLoad property. We will examine each of these in turn below.

You will also want to set the domain context property which you will do it explicitly as shown in the code that follows:

1: <riaControls:DomainDataSource x:Name="BlogsDataSource" 2: LoadSize="15" 3: QueryName="GetBlogs" 4: AutoLoad="True"> 5: <riaControls:DomainDataSource.DomainContext> 6: <ds:BlogsContext /> 7: </riaControls:DomainDataSource.DomainContext> 8: </riaControls:DomainDataSource>

 

The LoadSize property instructs the DomainDataSource control as to how many records to get for each query to the database.  This allows you to fine tune the performance of your application (too small load size, and you are making many calls to the database, to larg a load size and there will be a noticeable wait for the data to arrive).

The QueryName parameter references the query We created in the RIA Services class, you will remember setting GetBlogs to include bloggers. Notice that here you use the name of the method (GetBlogs ).  Rather than "GetBlogsQuery()" as you did in C#.

Setting Autoload to true tells the DomainDataSource control to load the first set of data when it is initialized.

Note that the namespace for BlogsContext is DS as opposed to RIAControls the namespace for the DomainDataSource.  DS is a namespace that refers to the Web project (you’ll need to add that to the top of the file)

Build and run the application.  The results, that is the running application, are identical to what you had before.  However now you are not creating this programmatically but rather declaratively in the Xaml.

Sorting

Is relatively straightforward to add sorting declaratively as well. You do so by adding a sort descriptor to your DomainDataSource control.  In the case shown below (Lines 9 through 11), we are setting the SortDescriptor property explicitly, and having it sort on BlogName.

  1: <riaControls:DomainDataSource x:Name="BlogsDataSource" 2: LoadSize="20" 3: QueryName="GetBlogs" 4: AutoLoad="true"> 5: <riaControls:DomainDataSource.DomainContext> 6: <ds:BlogsContext /> 7: </riaControls:DomainDataSource.DomainContext> 8: <riaControls:DomainDataSource.SortDescriptors> 9: <riaData:SortDescriptor PropertyPath="BlogName" 10: Direction="Ascending" /> 11: </riaControls:DomainDataSource.SortDescriptors> 12: </riaControls:DomainDataSource>

Sending the sort column in this way it causes the data grid to open with that column sorted.  The user, of course, can sort on any column by clicking on the column header.

Filtering

 

Before we leave the DomainDataSource control, let's take a quick look at filtering, which works much like sorting.  In this case rather than explicitly putting into our filter what it is we are filtering on, we will instead set the "Control Parameter" to point to another control on the same page that will provide the text on which to sort.

To begin, we'll add a text box into which the user can type the desired filter.

<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0,-16,0,0"> <TextBlock VerticalAlignment="Center" Text="Name Contains Filter" /> <TextBox x:Name="filterText" Width="75" FontSize="11" Margin="4" Text="Silverlight" /></StackPanel>

 

This code can be placed directly above the DomainDataSource, and as you can see it provides a textblock with a prompt and a text box, which will gather in the desired filter. Next We'll add a FilterDescriptors element to the DomainDataSource control, and tell it to get its value from that text box:

1: <riaControls:DomainDataSource x:Name="BlogsDataSource" 2: LoadSize="20" 3: QueryName="GetBlogs" 4: AutoLoad="true"> 5: <riaControls:DomainDataSource.DomainContext> 6: <ds:BlogsContext /> 7: </riaControls:DomainDataSource.DomainContext> 8: <riaControls:DomainDataSource.SortDescriptors> 9: <riaData:SortDescriptor PropertyPath="BlogName" 10: Direction="Ascending" /> 11: </riaControls:DomainDataSource.SortDescriptors> 12: <riaControls:DomainDataSource.FilterDescriptors> 13: <riaData:FilterDescriptorCollection> 14: <riaData:FilterDescriptor PropertyPath="BlogName" 15: Operator="Contains"> 16: <riaData:ControlParameter ControlName="filterText" 17: PropertyName="Text" 18: RefreshEventName="TextChanged" /> 19: </riaData:FilterDescriptor> 20: </riaData:FilterDescriptorCollection> 21: </riaControls:DomainDataSource.FilterDescriptors> 22: </riaControls:DomainDataSource>

 

The filter descriptors begin online 12 and run through line 21.  Notice on lines 14 and 15 that you are indicating which property is being filtered on and that you have your choice of operators such as contains, is, etc.  On lines 16 through 18, you indicate the name of the control that has the filter, the name of the property of the control from which to extract the filter, and the event on which you will update the filter.

N.B.: the code is showing updates each time a letter is typed in the text box.  This will cause a call to the database for every letter that's typed.  You can solve this by using the Load Delay parameter.  Of course having a low delay will make the page initially load more slowly, so you may want to add the load delay programmatically after you initialize the page.

Finally to give it a bit of polish, let's add a DataPager, just below the DataGrid.  Note that the binding for the DataPager is identical to that for the DataGrid, and that the DataPager retrieves 10 records at a time; we'll go up so that and change the DomainDataSource load size to 30, so that it will retrieve 3 pages-worth at a time.

<data:DataPager PageSize="10" Source="{Binding Data, ElementName=BlogsDataSource}" />

In which I describe how HTTParty has gotten lighter and more awesome since its initial release.

Right off the bat I would like to say that the divorce was completely amicable. I love ActiveSupport and use it with almost every project, even when haters complain. Originally, HTTParty�??s parsing of JSON and XML just used ActiveSupport�??s built in mechanisms and it worked great.

A few people brought up issues with ActiveSupport and I rolled my eyes. Then, once the roll was complete I thought about it and decided if I could use the JSON gem and find something comparable to ActiveSupport�??s Hash#from_xml, I would be ok with removing it. I did some research and stumbled across extlib�??s Hash#from_xml and liked it, so I ganked to power the XML de-serialization in HTTParty 0.2.0.

I removed ActiveSupport as a dependency and added the JSON gem. I then added a few core extensions, swapped out the de-serialization and HTTParty was free to date again.

But Wait, There Is More

So that update alone would probably be worth a blog post, but it is not the only thing that has changed since I first posted about HTTParty. Since it was suggested, I�??m going to show a few of the updates here as well.

Proxy Support

Thanks to francxk, you can now use proxies.

class MyProxyParty include HTTParty http_proxy 'proxyaddress.com', 80 end

Using the http_proxy method, you can set the address and the port of the proxy you would like to use. I�??ve never needed a proxy personally but I think this was a worth addition.

Format Detection Based on Content Type

When HTTParty was released, you had to declare a format if you wanted the response to be parsed in some way. For example, the old way of parsing the Twitter public timeline was the following:

class Twitter include HTTParty format :json end Twitter.get('http://twitter.com/statuses/public_timeline.json')

With the response content type detection, the new way is one less line of code and one less thing to remember.

class Twitter include HTTParty end Twitter.get('http://twitter.com/statuses/public_timeline.json')

Much thanks to Jay Pignata for adding this initially.

Automatically Follow Redirects

Alex Vollmer snuck into HTTParty like a thief in the night and added automatic following of redirects. With his addition HTTParty automatically follows up to 5 redirects, after which it will raise an HTTParty::RedirectionTooDeep exception. Feel free to bump up or down the redirect limit like this:

class RedirectFollower include HTTParty base_uri 'http://someurlthatredirects.com' end RedirectFollower.get('/foo', :limit => 2) HTML format

A few people mentioned that they would like a way to not automatically parse the response based on the content type. The simple fix for that was allowing an html format and making sure that format can optionally be passed in with an request.

class Twitter include HTTParty end puts Twitter.get('http://twitter.com/statuses/public_timeline.json', :format => :html)

Even though the request above returns the JSON content type, it will not be parsed as JSON, but instead will just return the JSON as plain text/html.

HTTParty.get/post/put/delete

One of my favorite additions was by Eli Miller, just a few days ago. We were chatting and he mentioned how he liked using HTTParty as a simple net/http wrapper. A few minutes later he sent me a pull request with a nifty addition that allows using HTTParty as a sane wrapper around net/http, without even making a new class and including HTTParty. You can now turn the Twitter public timeline into a ruby hash in one line thanks to Eli�??s addition:

HTTParty.get('http://twitter.com/statuses/public_timeline.json')

Yep, that is it. It will fetch the response, detect that it is JSON and use JSON.parse to turn the response into a Ruby hash. It really doesn�??t get any easier.

Conclusion

Ok, so now all you hold outs who haven�??t used HTTParty yet have absolutely no reason. Use it with Rails, Merb, Sinatra or whatever the heck other framework you use, with no worries about including all of ActiveSupport.

Yes you can import the VMDK.

 

First export the disk using vmkfstools with the 2gbsparse option, then import the disk in your ESXi.

 

Once the disk is imported, run vmkfstools -M

 

This will convert the VMDK from v2 to v3

I was working on a project recently, where I wanted to offer the user some fine grained control over transformation of display objects. A quick search led me to Green Sock, run by Jack Doyle. What can I say other than that Jack has tweening libraries for every flavor project and task. He also has a transform manager library, which at the time was only ActionScript 2. After an email exchange, Jack graciously provided me with an advance copy of his ActionScript 3 code base. That ActionScript 3 version is now done and you can purchase a license by heading over to the Green Sock web site.

Use Unfuddle? If you do and you see this error trying to clone a repository, it may be because:

This error looks to be happening because you are not explicitly involved in the project with which this repository is associated. You should note that even account administrators will need to be "involved" in a project in order to receive permissions to repositories associated with that project. In other words, if you add yourself to the project you should be able to connect to the repository.

Thanks to Unfuddle founder David Croswell for the solution. Worked like a charm.

The Silverlight Toolkit is innovative in many ways, not least of which is that controls are released in one of four quality bands:

• Mature: ready for release
• Stable: suitable for most scenarios
• Preview: suitable for most basic usage scenarios, may have moderate number of breaking changes as the control is developed.
• Experimental: intended for evaluation purposes

The control I�??ll be considering today was developed (and described here) by Ruurd Boeke and is currently in the Experimental band. You can expect that the API will change quite a bit, but that said, it is an enormously useful control right now; and thus I�??ve submitted a video and this write-up.

What�??s It For?

The goal of the Transitioning Content control is to make it easy to add animation when you are changing content within a control as demonstrated here. [You�??ll need to click on DomainUpDown on the left (and surprisingly, not on TransitioningContent!) and Animations on top. The following cropped image illustrates where to click, but provides only a shadow of the impact

Getting There In 3 Steps

To make this crystal clear, and to show how easy it really is to use this control, we�??ll build the example three times: first with a Content Control, then with a Transitioning Content Control, and finally, adding data binding and the ability to transition more complex objects.

Starting Simple

Version 0 begins with a grid with two columns. The left column contains a ContentControl and the right a button. Here is the complete Xaml:

<UserControl x:Class="tccDemo.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Width="300" Height="150">
<StackPanel Background="Bisque">

<ContentControl x:Name="cc1"
Content="Click button to change."
HorizontalAlignment="Center"
Margin="20"
FontSize="18" />

<Button x:Name="doChange"
Content="Change"
Width="80"
Height="30"
HorizontalAlignment="Center"
FontSize="14"/>

</StackPanel>
</UserControl>

The job of the ContentControl is to hold a single piece of content: in this case a string. The button�??s job is to cause that content to change, which we do programmatically in the button�??s click event handler in MasterPage.xaml.cs, shown in full:

using System;
using System.Windows;
using System.Windows.Controls;

namespace tccDemo
{
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
doChange.Click += new RoutedEventHandler( doChange_Click );
}

void doChange_Click( object sender, RoutedEventArgs e )
{
Random random = new Random();
cc1.Content = random.NextDouble().ToString();
}
} // end class
} // end namespace

Each time the button is clicked, a new value is displayed.

[ Demo here �?? visible only if you are running Silverlight 3 ]

Changing from Content to TransitioningContent

The TransitioningContent control is, essentially, a skinnable custom control that derives from content control.

For more on Skinnable Custom Controls, see the blog series that starts here, or consider these videos (click on the image to go to the video):

Before we dive into the TransitioiningContent control and how it does its work, let�??s look at how to use it. We start by replacing the ContentControl with a TransitioningContentControl, but to do this we need to add a reference to System.Windows.Controls.Layout.Toolkit in the references and a namespace to the top of the Xaml file

xmlns:layout="clr-namespace:System.Windows.Controls;
assembly=System.Windows.Controls.Layout.Toolkit"

With that in place we can modify MainPage.xaml to replace the ContentControl with the TransitioningContentControl and replace the Change button with two buttons: one for Up and one for down. Here is the complete Xaml:

<UserControl x:Class="tccDemo.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:layout="clr-namespace:System.Windows.Controls;
assembly=System.Windows.Controls.Layout.Toolkit"
Width="400" Height="200">
<StackPanel Background="Bisque">
<layout:TransitioningContentControl x:Name="tcc"
HorizontalAlignment="Center"
Margin="30"
FontSize="18"
Content="Click buttons to change content" />

<Button x:Name="UpButton"
Content="Up"
Width="100"
Height="30"
Margin="10"
FontSize="14"/>
<Button x:Name="DownButton"
Content="Down"
Width="100"
Height="30"
Margin="10"
FontSize="14"/>
</StackPanel>
</UserControl>

The code is modified only to set the Transition property of the TransitioningContentControl.  Here is the complete code behind file:

using System;
using System.Windows;
using System.Windows.Controls;

namespace tccDemo
{
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
UpButton.Click += new RoutedEventHandler( UpButton_Click );
DownButton.Click += new RoutedEventHandler( DownButton_Click );
}

void DownButton_Click( object sender, RoutedEventArgs e )
{
tcc.Transition = "DownTransition";
Random random = new Random();
tcc.Content = random.NextDouble().ToString();
}

void UpButton_Click( object sender, RoutedEventArgs e )
{
tcc.Transition = "UpTransition";
Random random = new Random();
tcc.Content = random.NextDouble().ToString();
}

}
}

Here is the effect:

Adding DataBinding and Objects

In both of the examples so far, the content has been a simple string. It is possible, however, to provide a more complex object, by modifying the TransitioningContentControl and using an explicit ContentTemplate.

<layout:TransitioningContentControl
x:Name="tcc"
Margin="20"
FontSize="18"
HorizontalAlignment="Center"
Content="Use buttons...">
<layout:TransitioningContentControl.ContentTemplate>
<DataTemplate>
<StackPanel >
<TextBlock Text="{Binding Title }"
FontFamily="Georgia"
FontSize="14" />
<TextBlock Text="{Binding Author }"
FontFamily="Georgia"
FontSize="14" />
</StackPanel>
</DataTemplate>
</layout:TransitioningContentControl.ContentTemplate>
</layout:TransitioningContentControl>

This follows all the normal conventions of using a ContentTemplate. We fill it with a DataTemplate which holds a StackPanel, allowing us to place two TextBlocks, both of which use binding syntax to indicate that they are going to bind to the Title and Author properties of whatever object they are given, respectively.

The rest of the Xaml file is unchanged.

We need a data object, and so we create as simple a data object as possible to illustrate this idea; noting that of course you can get your data from a database, from an XML file, etc.  Here is the complete contents of Book.cs including the static property we�??ll use to obtain some pre-created data,

using System.Collections.Generic;

namespace tccDemo
{
public class Book
{
public string Title { get; set; }
public string Author { get; set; }

public static List<Book> Books
{
get
{
List<Book> theBooks = new List<Book>();
theBooks.Add( new Book()
{ Title = "The Raw Shark Texts", Author = "Steven Hall" } );
theBooks.Add( new Book()
{ Title = "Columbine", Author = "Dave Cullen" } );
theBooks.Add( new Book()
{ Title = "Unfriendly Fire", Author = "Dr. Nathaniel Frank" } );
theBooks.Add( new Book()
{ Title = "The Inheritance", Author = "Dave Sanger" } );
theBooks.Add( new Book()
{ Title = "Sir Gawain and the Green Knight",
Author = "Simon Armitage" } );
theBooks.Add( new Book()
{ Title = "The Superorganism", Author = "Holldobler and Wilson" } );
return theBooks;
}
}
}
}

 

MainPage.xaml.cs is modified somewhat more significantly, to hold a membervariable of type List<Book> (thus avoiding having to �??get�?� the data repeatedly) and a counter as a convenience so that we can cycle through our somewhat meager collection.  Here is the complete MainPage.xaml.cs

using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;

namespace tccDemo
{
public partial class MainPage : UserControl
{

private List<Book> books = Book.Books;
private int counter = 0;

public MainPage()
{
InitializeComponent();
tcc.Transition = "Normal";
tcc.Content = books[counter++];
UpButton.Click += new RoutedEventHandler( UpButton_Click );
DownButton.Click += new RoutedEventHandler( DownButton_Click );
}

void UpButton_Click( object sender, RoutedEventArgs e )
{
tcc.Transition = "UpTransition";
tcc.Content = GetBook();
}

void DownButton_Click( object sender, RoutedEventArgs e )
{
tcc.Transition = "DownTransition";
tcc.Content = GetBook();
}

public Book GetBook()
{
if ( ++counter >= books.Count )
counter = 0;
return books[counter];
}
}
}

The constructor sets the initial visual state to Normal and sets the content of the TransitioningContentControl to the first book in the collection. It then sets up the two event handlers. The job of each is to set the Transition state and then call the helper method that gets the next book in the collection. Here it is in action:

Visual State Ambivalence

The TransitioningContent is a bit ambivalent about its visual states. There are four states that are hardwired into the control as it is currently written:

• Default
• Normal
• UpTransition
• DownTransition

However, if you examine the attributes at the top of the class (used to signal, for example, both the Visual State Manager and tools like Blend what visual states the class supports) you�??ll find this:

[TemplateVisualState(GroupName = PresentationGroup,
Name = NormalState)]
[TemplateVisualState(GroupName = PresentationGroup,
Name = DefaultTransitionState)]
[TemplatePart(Name = PreviousContentPresentationSitePartName,
Type = typeof(ContentControl))]
[TemplatePart(Name = CurrentContentPresentationSitePartName,
Type = typeof(ContentControl))]
public class TransitioningContentControl : ContentControl

There are precisely two visual states made visible to Blend and the VSM.  The net effect is that you can certainly use the UpTransition and DownTransition, but they were added as examples of how you can freely extend this class with any transitions you like.

Here�??s how it works. The TransitioningContentControl consists of two parts both of type ContentControl: PreviousContentPresentationSitePartName and CurrentContentPresentationSitePartName. 

To add an animated transition from content A to content B you need only hand the two to this control and tell it, by passing in a string, what storyboard to invoke.  If you pass in the string TransitionUp or TransitionDown then it already knows what storyboard to invoke, as Ruurd Boeke wrote those and put them in the Resources section of TransitioningContentControl.xaml.  Here, for example, is his UpTransition:

<vsm:VisualState x:Name="UpTransition">
<Storyboard>
<DoubleAnimationUsingKeyFrames
BeginTime="00:00:00"
Storyboard.TargetName="CurrentContentPresentationSite"
Storyboard.TargetProperty="(UIElement.Opacity)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0"/>
<SplineDoubleKeyFrame KeyTime="00:00:00.300" Value="1"/>
</DoubleAnimationUsingKeyFrames>

<DoubleAnimationUsingKeyFrames
BeginTime="00:00:00"
Storyboard.TargetName="CurrentContentPresentationSite"
Storyboard.TargetProperty="(UIElement.RenderTransform).
(TransformGroup.Children)[3].(TranslateTransform.Y)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="30"/>
<SplineDoubleKeyFrame KeyTime="00:00:00.300" Value="0"/>
</DoubleAnimationUsingKeyFrames>

<DoubleAnimationUsingKeyFrames
BeginTime="00:00:00"
Storyboard.TargetName="PreviousContentPresentationSite"
Storyboard.TargetProperty="(UIElement.Opacity)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="1"/>
<SplineDoubleKeyFrame KeyTime="00:00:00.300" Value="0"/>
</DoubleAnimationUsingKeyFrames>

<DoubleAnimationUsingKeyFrames
BeginTime="00:00:00"
Storyboard.TargetName="PreviousContentPresentationSite"
Storyboard.TargetProperty="(UIElement.RenderTransform).
(TransformGroup.Children)[3].(TranslateTransform.Y)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0"/>
<SplineDoubleKeyFrame KeyTime="00:00:00.300" Value="-30"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</vsm:VisualState>

The effect of this is to target first the opacity of the current content, which will go from 0 to 1 over 3/10 of a second. During that same time period it will move up the Y axis from 30 to 0 (remember that the Y axis counts up as it moves down the screen).  In the second half of the animation the targetproperty is the opacity of the previous content which fades away from 1 to 0 over that same 3/10 of a second, while the content itself moves up from 0 to �??30.

Notice that the storyboard is within the VisualState whose name is UpTransition.

The class itself has a public property named Transition:

/// <summary>
/// Gets or sets the name of the transition to use.
/// These correspond directly to the VisualStates inside
/// the PresentationStates group.
/// </summary>
public string Transition
{
get { return GetValue(TransitionProperty) as string; }
set { SetValue(TransitionProperty, value); }
}

This acts as a front for the Dependency Property which is registered immediately below

public static readonly DependencyProperty TransitionProperty =
DependencyProperty.Register(
"Transition",
typeof(string),
typeof(TransitioningContentControl),
new PropertyMetadata(OnTransitionPropertyChanged));

A quick review of the Silverlight documentation reveals the meaning of each of the four parameters:

Notice that the type of the TransitionProperty is string, and parenthetically, notice that the final parameter, typeMetadata,  is explicitly noted for usage with a PropertyChangedCallback, which is what is done here.

OnTransitionPropertyChanged is overloaded in the implementation, but the net effect is to set the source of the content control and to set the string representing the new transition and then to call ChangeTransition whose job is to make sure it is safe to set a new transition, and then to obtain the PresentationState Visual State group and then to look to see if there is a state for the string passed in. If so, that transition is set as the new value for the transition.

Thus, with this somewhat unusual control,  you can modify the visual states within the PresentationGroup) without subclassing, and by doing so (and providing a storyboard) you can add any transition you like, which you can then invoke by passing in its name!

Caveat! As noted earlier, this control is in the experimental band, and this API is very likely to change.

I hope you found this bit of control spelunking as interesting as I did sorting it out; and it is just fine to set all of the details aside and just use the control in conjunction with other controls to create animated transitions without over-worrying about how it is doing its magic.

Ahora que han pasado unos meses desde el lanzamiento de Java 6 y que en casi en cualquier provincia puedes expedir un dni electrónico ya podemos empezar a pensar como hacer uso de ambos.

Dentro de nuestro dnie se encuentran varios certificados digitales para firma electrónica o autenticación, para acceder a ellos necesitamos es un lector de tarjetas que acepte nuestro documento.

Una de las nuevas incorporaciones en java 6, y de las menos publicitadas, es el soporte nativo para acceder al almacen de claves de windows. Hasta ahora teníamos que usar complejas DLLs de windows para acceder a este almacen, pero con esta nueva release es tan fácil como esto:

KeyStore keyStore = KeyStore.getInstance("Windows-MY"); keyStore.load(null, null);

Como no todos en este mundo usamos ese sistema operativo, dentro de nuestro dnie también podremos encontrar los certificados dentro de una librería PKCS#11 llamada opensc-pkcs11.so que podremos usar en cualquier otro sistema. El proceso de acceder a una librería PKCS#11 es un poco más tedioso pero hay muy buenos artículos en la red que lo explican . Una aproximación rápida podría ser que tenemos que añadir esta librería como un proveedor de certificados a nuestro almacen de claves PKCS#11 y luego acceder a este para recuperar los certificados. Para añadir la librería a nuestro almacén necesitaríamos algo como esto:

String pkcs11config = "name = DNIE\nlibrary = opensc-pkcs11.so "; InputStream confStream = new ByteArrayInputStream(pkcs11config.getBytes()); Class sunPkcs11Class = Class.forName("sun.security.pkcs11.SunPKCS11"); Constructor pkcs11Constr = sunPkcs11Class.getConstructor(InputStream.class); Provider pkcs11Provider = (Provider) pkcs11Constr.newInstance( confStream ); Security.addProvider(pkcs11Provider);

para acceder a este almacén:

KeyStore keyStore = KeyStore.getInstance("PKCS11"); keyStore.load(null, password);

Una vez cargado nuestro almacén de claves correspondiente podríamos acceder a todos los certificados que contiene a través de sus alias:

keyStore.load(null, null);

Cuando hablamos de diseño web, sobre todo en la fase propiamente de diseño en programas de edición de gráficos, es relativamente frecuente observar un efecto conocido como �??page curl�?� o pliegue de página.

Para entendernos todos, es el efecto que observamos cuando pasamos las páginas de un libro por ejemplo.

Si quieres agregar un toque curioso a tu sitio web y agregar una esquina que se doble para mostrar el contenido de debajo te vendrá bien este plugin libre para jQuery creado por Elliott Kember.

Para hacerlo funcionar sólo necesitarás usar jQuery y jQuery UI (preferiblemente la versión 1.5) con el módulo resizable. Luego con un par de líneas de código y creando un elemento con id �??target, que contendrá lo que quieras que se vea tras la página, estarás listo.
