Does HTML5 Really Beat Flash?

With the impending launch of the Apple iPad, the Cupertino-based company's shunning of Adobe Flash technology has been brought to the forefront of technological discussions. While it was one thing to forgo Flash on a small, mobile device such as the iPhone or iPod Touch, some are questioning whether lack of Flash support is going to be a make-it-or-break it feature for the new slate devices arriving next month - devices which, if you believe Apple CEO Steve Jobs - are "better than netbooks."

On the flip side, Apple supporters echo the company's sentiments that "Flash is a CPU hog" and including support for the technology in Apple's mobile line-up would negatively impact battery life.

However, recent tests have put Flash up against HTML5, the new web markup language that eliminates the need for the Adobe plugin. The results of these tests show that this is not a simple black-and-white issue. Is Flash really a CPU hog? Yes, in some cases. But, surprisingly, not all the time. In fact, sometimes HTML5 actually performed worse.

Testing Flash and HTML5

Jan Ozer is an expert in video encoding technologies, has worked in digital video since 1990 and is the author of 13 books related to the subject. Recently, he put HTML5 up against Flash in a series of tests that pitted the two technologies against each other on both the Mac and PC and in different web browsers including Internet Explorer 8, Google Chrome, Apple Safari and Mozilla Firefox.

The results of the tests in their entirety are published here on StreamingLearningCenter.com. The summary in a nutshell? Flash isn't always a CPU hog, sometimes that honor goes to HTML5.

Some of the highlights of Ozer's findings are below, broken up into both Mac and Windows test results.

Mac Tests

  • With Safari, HTML5 was the most efficient and consumed less CPU than Flash using only 12.39% CPU. With Flash 10.0, CPU utilization was at 37.41% and with Flash 10.1, it dropped to 32.07%
  • With Google Chrome, Flash and HTML5 were both equally inefficient (both are around 50%)
  • With Firefox, Flash was only slightly less efficient than in Safari, but better than in Chrome

Windows Tests

  • Safari wouldn't play HTML5 videos, so there was no way to test that. However, Flash 10.0 used 23.22% CPU but Flash 10.1 only used 7.43% CPU
  • Google Chrome was more efficient on Windows than Mac. Playback with Flash Player 10.0 was about 24% more efficient than HTML5, while Flash Player 10.1 was 58% more efficient than HTML5.
  • On Firefox, Flash 10.1 dropped CPU utilization to 6% from 22% in Flash 10.0
  • In IE8, Flash 10.0 used 22.41% CPU and Flash 10.1 used 14.62% CPU

Hardware Acceleration Key to Flash Performance

In analyzing the results of the tests, Ozer determined that the key to better Flash performance was dependent upon whether or not it could access hardware acceleration. This feature, launched in Flash 10.1, allows the plugin to use the graphics processing unit (GPU) on some computers to decode video. Depending on the video card and drivers, (NVIDIA, AMD/ATI and Intel offer products that support this), the video decoding process in Flash 10.1 can now work for all video playback, not just full-screen playback as was available in Flash 10.0.

According to Adobe, hardware acceleration is not supported under either Linux or Mac OS X, the latter because Mac OS X does not expose access to the required APIs. Adobe goes on to say "The Flash Player team will continue to evaluate adding hardware acceleration to Linux and Mac OS X in future releases."

Here's what this all means in layman's terms: Apple isn't allowing Flash to become more efficient on their Mac OS X/Safari platform (or their iPod/iPhone/iPad one, either) by not providing the access to the hardware it needs to reduce its CPU load. Adobe is waiting and watching to see if they do, but, as Ozer says "the ball is in Apple's court."

Will Apple budge? At this point, it's unlikely. In blocking Flash on Apple devices, the company can easily claim that it's simply not an efficient technology...and that's true for now, considering how it's set up. But if the company wanted to allow it and make it work, it seems reasonable to believe that they could. This is what leads some insiders to believe that the decision to block Flash is less of a technological one and more of a business-minded one. After all, if you could easily visit Hulu.com (or, overseas, the BBC iPlayer, for example) to stream TV shows and movies, then why would you need to buy them from the iTunes Store?

So while Flash's "CPU hogging" may be a contributing factor in Apple's decision to not support the technology on their mobile devices, that's probably not the only reason behind the block.

Reflexiones de un Venezolano en el exterior

Viví en Caracas durante dieciséis años. Caí preso en las marchas estudiantiles del año 2007 a favor de la libertad de expresión, fui víctima de un secuestro express y meses después víctima de treinta motorizados, los cuales, además de darme una golpiza, destruyeron mi auto.

Después de estos hechos desconcertantes, decidí tomar un avión sin boleto de regreso. Ahora trabajo en un bar en un lugar perdido de Europa, día a día, sin descanso..

La gente que pasa me pregunta si extraño a mi país y si algún día volveré. A todos les respondo que no, que nunca más. Ante esta dura afirmación, muchos se entristecen y me dicen que soy demasiado joven para sentenciar tal cosa.

Tomando el consejo que me dan, intento despistar mi adversidad y me pregunto: "¿amo a mi país?". La única respuesta es un "¿Por qué debería?"

Retomo apuntes mentales y me pongo a pensar en mi infancia y mi adolescencia, en los hechos de mi vida allá y me doy cuenta de que no, de que no lo extraño en lo más mínimo y no volvería con o sin el actual gobierno.

¿Por qué?

Mi país me enseñó que quien trabaja, sueña y se esfuerza, termina mal: la idiosincrasia del venezolano está basada en la picardía. Es alabado aquel que se comporta como un oportunista y el honrado que se esfuerza, es descaradamente rechazado.

Mi país me enseñó que la vida de ningún hombre vale nada: en las calles matan semanalmente un centenar de personas, en el este y el oeste de la capital, con impunidad total, sin estar en guerra, sin justificaciones razonables.

Mi país me puso una pistola tres veces en la cabeza y tres veces tuve la certeza de que moriría, entregándome a ella, sintiéndome en el absurdo de que moriría como un perro porque así morimos los venezolanos.

Mi país me enseñó que es peligroso tener un automóvil propio, vestirse bien o hablar educadamente, con un acento diferente: cualquier excusa es buena para robarte o secuestrarte o matarte..

Soy el hijo de un italiano y una venezolana de izquierda. Me enseñaron valores socialistas desde pequeño. Más que catalogarlos en una ideología, debería llamarlos humanos. Valores congruentes al humanismo, como que todos deberíamos tener las mismas oportunidades, los mismos derechos. Como que todos deberíamos tener la posibilidad de ascender, porque no es culpa del individuo sino del sistema que está podrido.

Mis padres me enseñaron que no todos somos iguales pero todos, de donde sea que vengamos, cual sea nuestra educación, valemos lo mismo y eso debe respetarse para poder vivir en armonía y progresar.

Eso me enseñaron en casa pero mi país me hizo racista y clasista, al punto de que veía un negro mal vestido y con jerga callejera y le tenía miedo, desconfianza. Por lo mismo que parte de la idiosincrasia venezolana, me hizo sentir que todo aquel que era pobre, era un posible criminal.

Trabajando como mesonero en Europa, gano como debería ganar un profesor allá (no como gana). Y no tanto lo que gano sino el poder adquisitivo que existe: un sueldo mínimo me ayuda a vivir en una habitación con servicios pagos y comer bien durante un mes, cosa que allá sería imposible haciendo el mismo trabajo.

Un estudiante de clase media aquí tiene una vida digna, con un transporte público que se conecta con toda la ciudad, precios favorables en ropa, comida y materiales de estudio. Cosas tan precisas para el bienestar del Hombre, en mi país ya ni siquiera se proponen.

Es impresionante.

Una clase social dividida en extraños estratos: la pobre, que vive en los barrios; la media, que va en extinción y gasta dinero en cosas desproporcionadas e innecesarias, como ir a lugares de moda a no hacer nada; la rica, que sobrevive a los ataques actuales del comunismo; y la nueva rica, que acelera su enriquecimiento por parte de los dirigentes del gobierno.

Se han perdido valores necesarios, como leer un buen libro, viajar por conocer, luchar porque las cosas cambien. Por eso no tenemos ni tendremos nunca un Nobel escritor.

No tenemos bases suficientes a nivel educativo ni de valor humano. Pero la cosa que no le perdonaré nunca a Venezuela es que me enseñó a tener miedo.

Miedo de salir a la calle de noche, de ir caminando a comprar cualquier cosa. Miedo de reprender a dos ladrones que roban a una muchacha a plena luz del día. Miedo a volver todas las noches de la universidad a mi casa porque, entrando, podrían secuestrarme o asesinarme para llevarse el auto.

Todo ese miedo que me enseñó mi país, lo convertí en rabia.

Una rabia amarga e insoportable que me hace no querer volver nunca más. Una rabia donde metí mis militancias políticas donde creía que un mundo mejor era posible, donde guardé mis sueños de vivir de playa y ciudad a veinte minutos de distancia, donde dejé solo el cariño hacia mis conciudadanos. Una rabia que me hizo cínico ante cualquier idealismo joven e inocente.

Un cinismo que me rompió la imagen del Che, me rompió el sentido de las canciones de Lennon, las de Silvio Rodríguez, las de la Primavera de Praga, las de las fuerzas Aliadas haciendo Jaque Mate a Hitler, el valor de las Madres de Plaza de Mayo, el rostro de Rómulo Betancourt llevándonos a la democratización, el sentido de mi amado Bolívar y rompió la fuerza de Francisco de Miranda y las ideas del Ilustrismo.

Mi país acabó con cualquier decencia, con cualquier pedazo bueno que tiene la juventud, ocasionando un vacío ridículo y un cinismo aún mucho más grande. Estoy seguro que las cosas allá no cambiarán ahora ni nunca. Estaban mal antes de este gobierno. Empeoraron demasiado, pero ahora se empeñan en echar culpas después de 10 años!!! de poder total y descomunales ingresos... no les interesa resolver nada, sólo destruir.

Después de esto (suponiendo que exista un después), habrá cada vez más caos.

Nuestros dirigentes gobierno y oposición parten del principio de la picardía y lo que buscan es dinero y protagonismos. Ninguno tiene bolas para dejar la piel en el asfalto porque ninguno realmente quiere una República. Aquellos valores de pureza, honor y verdad, están menospreciados.

Por eso nuestros militares reciben dinero y cumplen órdenes sin chistar. El gobierno cierra radios y medios de comunicación atentando contra la libertad de expresión para que nadie se entere de la cruda y triste realidad.

La culpa no está sólo en ese ignorante que nos comanda sino en las bases que parten de un mal principio de nuestra equivocada sociedad. Nada de esto lo digo para crear un debate ni para intentar que me cambien la visión.

No lo digo para que me cataloguen en una izquierda o en una derecha. Lo digo como alguien que ahora es externo y que no le interesa en lo más mínimo lo que ocurra. Dejé que me interesara hace tiempo, sin quererlo.

Entonces no, no extraño ni extrañaré nunca aquel caos injusto de donde vengo.

Twitter habilita Firehose para algunos startups

When it comes to getting access to all the data that flows through Twitter, there are the 50,000 apps that drink from Twitter%u2019s Streaming API, which is subject to various limits. And then there are the chosen few who get the full unlimited firehose of data, the more than 50 million Tweets a day coursing through Twitter.

In the past, only select partners, particularly big search engines such as Google or Bing, got the full firehose. Search engines need it more than others to be able to index and serve up results in realtime. Today, smaller search startups are also getting the firehose. These include Ellerdale, Collecta, Kosmix, Scoopler, twazzup, CrowdEye, and Chainn Search (which has not yet launched).

In December at Le Web, Twitter indicated that the firehose would open up to more and more developers. This is a step in that direction.

And while Twitter makes deep-pocketed partners like Google and Bing pay for the firehose, it treats startups differently with more favorable (even free) terms, or at least it used to. These aren%u2019t the first startups to get the firehose, and they won%u2019t be the last. Once they get to a certain size though, they%u2019ll pay if they don%u2019t already. Apparently it works on a sliding scale.

Is Facebook secretly planning an internet-wide payment platform?

 Link to this post:
 http://www.google.com/buzz/100535338638690515335/Vt1b7nZ6ZdZ/Is-Facebook-secretly-planning-an-internet-wide

12:05 pm Louis Gray: Is Facebook secretly planning an internet-wide payment platform? - Royal Pingdom
12:11 pm Samuel Wood: I would not use Facebook credits to purchase from Amazon, or to order pizza, or anything else. I can do all that now without Facebook credits.

I might use Facebook credits to transfer cash to other people. A surprising amount of people find Paypal difficult to use. No, I have no idea why.

But if Facebook could make it easier for me to pay people directly, and in real money instead of credits (they need a "withdrawal" mechanism, basically), then I might have a legitimate use for it.
12:14 pm Eric Matas: I'd like to see Facebook allow people with "Credits" to buy friendship...or make people join their mafia. Make it interesting!
12:15 pm Louis Gray: I can see this being successful. The question is, why has PayPal been a success where Google Checkout and Google payments are less visible? Could Facebook do well here thanks to brand recognition for the non-techie market?
12:17 pm Jonathan Greene: using facebook connect though to login on a site and pay via whatever is in your "wallet" is very interesting. You can already have a credit card in your profile and now paypal. Seems like Facebook connect is in WAY more places already than Google Checkout ... even Amazon Payments. It's easy ... and very global.
12:23 pm Ben Parr: In a blatant attempt to toot my own horn, I called this back a full year ago. - http://mashable.com/2009/03/28/facebook-virtual-currency/

;)
12:24 pm Linda Lawrey: Just not a fan of credits or payments for virtual goods.
12:38 pm Ian Wright: If Facebook ties up with a global mobile company or buys one itself and moves seriously into this territory then they will have a real opportunity. Given social media uptake usage is being driven by mobile smartphone growth I wouldn't be surprised if we see a similar event occuring on Buzz/Android tie ups. Interesting piece as always Louis.
12:42 pm Louis Gray: That is blatant, Ben. Should I delete it as spam? :)
12:46 pm Jonathan Terleski: Credits work well for micro-payments. They get you out of the mindset that you're paying "X dollars" or "Y cents" for something. It also changes the judgement point -- you've already pre-paid for 400 credits ... now you just need to spend them. Additionally, if I already have a stack of 390 Credits so I can buy non-sense on FarmVille, I might just be willing to throw 10 of those credits at a NYTimes article..
12:49 pm Jeffrey Canton: I'd agree with Samuel - short of transferring to other facebook contacts (towards which I'm already not particularly inclined) I can't imagine using this for much. I barely trust Facebook with my photographs ... :-P
12:52 pm Stephen L Harlow: Selling products on Facebook by Andréa Maria Cecil "Facebook said it would collect 30 percent on the purchases of virtual goods made with Facebook Credits" http://ow.ly/1cOPs

Q - What charge will be too much for actual goods and money transfers?
2:07 pm shanta clark: really i think that its stupid because aint no body fina pay for no stupid shit like that and plus people
got bills to pay HELLO
2:07 pm jordan johnson: fuck that if facebook does that everybody just goin to go back to myspace and tagged...facebook who
ever is plaining to do that you are stupid as fuck u prick....
2:17 pm Ru Viljoen: It would probably work really well and since facebook is encouraging companies to have pages it could extend beyond your friends. In my googlevsfacebook mind I still hope facebook fails miserably though. These buzz commenters are over the top btw.
4:50 pm Richard Zeidel: and we're all worried about google... Research shows we're most 'real' on FB. With FB Connect and a payment platform FB is increasingly becoming THE WEB for most people.
6:48 pm Thomas Power: Facebook is becoming a bank it's obvious with a billion users 2012 what else can they do? http://www.ecademy.com/node.php?id=145288
6:56 pm Sam Sethi: I heard that every site that includes FB connect code will have the option of taking Facebook "AdSense". This will be the biggest threat to Google's core revenue. The question I keep asking is will Facebook ever launch their own search engine.
7:07 pm Thomas Power: Yes of course they will Sam initially using Bing and then their own version. To MZ this whole thing is just a computer game. http://www.ecademy.com/node.php?id=145538
7:18 pm Holden Page: My parents and friends would use it in a heart beat.
7:22 pm Thomas Power: The winner of the game is the one with all the names - 2012 Zuckerberg wins with one billion names unless Google is serious about a fight. Google have to buy Twitter to respond to FB and who's to say what MS and Apple decide? Facebook will catch and pass Google in 2011 and that's before they add Search and Banking http://www.alexa.com/siteinfo/facebook.com
9:34 pm Richard Walker: And how, pray tell, will they mesh this with their policy of account shutdown on suspicion your name isn't "real"? (Irina Slutsky, already happened, confirmed in a Steve Rubel Buzz).

I'd love to see the steam coming out of people's ears when they either can't cancel payment, or can't make payment, because of a Facebook issue for which there is no live human support. Also, if payments need to be authenticated with third parties, Facebook may find out that some people aren't using real names after all, causing a whole new wave of shutdowns for TOS violation. I dunno, but I'm skeptical and in a *facepalm*-y mood :)
9:42 pm Jonathan Greene: Richard - an interesting issue for sure. Don't the same challenges apply with PayPal in general. You are as good as your password
9:58 pm Brian Hayashi: Not all transactions need to be evaluated using the same criteria as credit card transactions. Think of Facebook enabling an alternative to gift cards, acting as guarantor.
10:07 pm Richard Walker: Jonathan - yes indeed, but I'd think it strange if Paypal were to suggest.... "buy your Auntie a Hallmark card, seeing as she has been so lonely recently and all. And while you're there, sign up a few of your friends to the service and we'll cut you in on their misc. fees and surcharges. Did you know we have a 2-for-1 Farmville on SecondLife offer? Do you mind if I tell your friends about it? Great! There's only one problem though, your pets need accounts too, so that your friends can buy them treats.... "

you get my point, I'm sure
10:29 pm Jonathan Greene: Richard I do get your point, but it's your friends not Facebook making all those crappy recommendations ... or at least the crappy apps they choose to besiege you with. Farmville be gone!
10:38 pm Richard Walker: But that's where the problem is... Facebook has a direct interest in spreading itself, and Farmville helps to do that. When that is coupled with a direct interest in getting you to make transactions, you have a viral bank with access to your entire social sphere, and many ways it can data mine everything. I'm sure Zuckerberg is a visionary of sorts, but this proposition has too many bad incentives and too few promises for the "consumer."
10:43 pm Jonathan Greene: this should help considerably - http://www.readwriteweb.com/archives/facebook_silences_app_notification_spam.php
