Como funciona multitarefa nos dispositivos móveis?

O iPhoneOS 4 irá permitir que 7 tipos de funções rodem em multitarefa, como música, tráfego de rede, voip, tudo isso de modo leve, pois não irá rodar a aplicação inteira em plano de fundo, apenas a parte da API. O Android funciona com um multitarefa que faz uma espécie de cópia e reciclagem da memória de programas que estão em plano de fundo a medida que precisa liberar mais memória e recursos. O Windows Mobile 7 só receberá notificações de aplicações e enviará notificações para aplicações em plano de fundo, basicamente só conseguirá executar uma aplicação por vez.

Giz Explains: How Multitasking Works on a Phone - Gizmodo:

"A smartphone is a computer that fits in your pocket, but it has some constraints that a desktop doesn't, which make multitasking far trickier (hence the reason we're even explaining it). Namely, these four resources are constricted, and they're what mostly shape the way multitasking works on phones:

Screen real-estate: There's only so much you can do with a 3-to-4 inch screen at one time
Battery life: You want your phone to actually last all day, or come close to it, right?
CPU: It's slower than anything in a laptop, because of size and battery life
Memory: There's not that much of it, also partly because of battery life"


As cinco maiores empresas de celular em vendas

A RIM, fabricante do BlackBerry, ultrapassou a Sony Ericsson e é agora uma das cinco empresas que mais venderam celular no mundo. Para valores de janeiro a março de 2010, a Nokia, que é a primeira, vendeu 108 milhões de celulares, a Samsung 64 milhões e a LG 27 milhões, no mercado americado a Apple ultrapassou a Motorola, vendendo 8.85 milhões de celulares no último trimeste.

Top Five Mobile Phone Vendors - IDC:

"Nokia started the year with a strong first-quarter unit shipment performance, driven by its top-selling 5130 and 2700 models. Shipments of 107.8 million in 1Q10 represented a nearly 16% improvement over the same quarter last year. The overall figures, however, fell short of the first-quarter high it set in 2008. Converged mobile device shipments increased sharply on a year-over-year basis due to top-selling models such as the 5230, 5800, 5530, and X6. However, average selling prices for converged mobile devices dropped to €155 in 1Q10, compared to €186 in the previous quarter. Nokia plans to ship the N8 (the first converged device to run the Symbian 3 operating system) in the third quarter. The N8 will cost €370, according to Nokia, and is expected to boost Nokia's overall ASP.

Samsung held steady as the number two vendor worldwide for the twelfth consecutive quarter with total shipment volumes greater than those of the next three vendors combined. Driving its results was a combination of new devices launched and expansion of distribution channels within emerging markets. Moreover, efforts to bring high end devices, including touchscreen phones and converged mobile devices, pushed ASPs higher. Samsung plans to launch more Android and bada-powered devices later this year while launching more touch-enabled devices for the mass-market.

LG Electronics remained the number three vendor worldwide with year-over-year shipment growth of nearly 20%, but declining revenue and profit due to seasonality and reduced prices. The abundance of feature phones at varying price points kept the company in good stead with carriers and customers, particularly within emerging markets where LG reaped triple digit growth. Still, the lack of a broad and deep smartphone portfolio made it vulnerable to competitor share gains, particularly within North America. LG plans to introduce several Android, Windows Mobile 6.5, and Windows Phone 7 devices later this year while expanding its global platform to reach new markets.

Research In Motion makes its first appearance among the top five vendors worldwide, with total shipments surpassing those of Motorola by nearly 2 million units. Research In Motion is the only vendor in the top 5 with a singular focus on smartphones, and as a result, the company enjoys the highest average selling prices within that group. Key to its success in the first quarter was the popularity of its BlackBerry Curve 8520 and BlackBerry Bold 9700 across multiple markets as well as its global prepaid offerings. Strong consumer adoption, particularly among text-crazy teens, has also fuelled demand for BlackBerry devices.

Sony Ericsson returned to profitability in the first quarter due to cost cutting and new product introductions. The joint venture launched six new handsets including three new Greenheart models - Aspen, Elm, and Hazel - as well as the Xperia X10 and Vivaz converged devices. Average selling prices rose 12% as Sony Ericsson pruned several less-profitable products from its lineup. However, overall shipments in the first quarter fell 28%. Three new converged devices – the Vivaz pro, Xperia X10 mini, and Xperia X10 mini pro – will ship towards end of the second quarter.

Apple iAds: Anúncios podem chegar a custar 10 milhões de dólares

Com um nicho de mercado fiel e disposto a pagar valores premium por produtos de marca, os usuarios dos produtos iPhone, iPad e iPod são o alvo ideal para propagandas do iAds, que espera também ter como parceiros anunciantes marcas que estejam dispostas a pagar pelo menos 100 a 200 mil dólares, sendo que anúncios podem chegar a custar 10 milhões.

Apple iAd Aims Upscale - Information week:

"High-profile partners are being sought by Apple for its iAd platform, ones willing to pay well and make a splash.

Apple has done what nearly every ad network wants to do: find a way to turn millions of high-end consumers with a disposable income-the very consumers who buy Apple products-into a captive audience for advertisers," said Mark Simon, VP of industry relations for search engine marketing firm Didit, in an e-mail. "Obviously, Apple wants to tap into that audience to offer advertisers a direct, premium ad buy."

Apple announced iAd when it presented a preview of its iPhone OS 4.0 earlier this month. In an attempt to differentiate the iAd experience from other mobile advertising, the company said that iAds will combine the emotional impact of television ads with the the interactivity of Web ads."


Lala vai fechar dia 31 de Maio

Não é tanta surpresa que o site irá fechar após a Apple comprá-la, para quem não conhece, o Lala é um site de compra e streaming de música, oferecendo serviços parecidos ao iTunes, só que totalmente web, sem precisar instalar um programa.

Não vou me surpreender se em breve a Apple anunciar um iTunes web.

Trecho da notícia original e link:

Lala closing on May 31st, web songs and unused credit will head to iTunes - Engadget:

"Can't say we're too surprised -- after all, it does somewhat compete with new management -- but still, we're quite sad to see that as of May 31st, Lala is closing its music-streaming doors to the world, and no new users will be accepted. Existing users, however, can take solace in some pretty nice parting gifts. According to the site, all money spent purchasing web songs -- soon to be rendered null and void by a loss of service -- will convert to iTunes credit. Ditto for wallet balances and unredeemed gift cards, although with those you can get a refund via check, if you choose to. As for the future of its staff, well, we're still waiting to see all the fruits of Apple's acquisition. In the meantime, crank your speakers, raise them high over your head, and let's make this month count."

HTC Droid Incredible esgota após 2 horas de lançamento

O telefone da HTC com o sistema operacional Android, da Google, mal lançou e ja acabou...


Segue trecho da notícia com o link original:

HTC DROID Incredible sold out, new orders ship May 4th - Boy Genius Report: "In the real world, the early bird catches the worm..and in the world of mobile technology, the early bird gets the phone. Such is the case with the highly anticipated HTC DROID Incredible, which debuted early this morning on Verizon Wireless' website, and sold out within two hours. We don't know how many units Verizon Wireless had on hand, but the initial inventory is long gone, and all new orders will not ship until May 4th. If you absolutely must have Android's latest and greatest handset, you will have to try your luck at your local Verizon Wireless store. Happy hunting!"

Apple Buys Siri, a Small Victory in Mobile Web War with Google - Search Engines from eWeek

A Apple comprou a empresa que faz Siri.. não, não é o crustáceo.

O Siri é um assistente pessoal no melhor estilo Jarvis do filme Homem de Ferro, você fala com ele, diz que quer ir pro restaurante, que tipo de comida, e ele já faz as reservas para você e tudo mais... porém, atualmente só está disponível em inglês.

Acompanhando a corrida de aquisições de empresas para mercado móvel entre a Apple e o Google.

Apple Buys Siri, a Small Victory in Mobile Web War with Google - Search Engines from eWeek: "Siri co-founder Norm Winarksy confirmed Apple has acquired startup Siri, whose virtual personal assistant application lets users of the Apple iPhone 3GS book restaurant tables, buy movie tickets and perform several other tasks all by
speaking into their device. Apple did not comment on the buy, which marks a win for the computer maker as it fends off Google, Nokia and others in the arms race for applications that provide consumers with valuable mobile Web resources. Given Apple's approach of keeping everything regarding its applications and platforms in-house, it is doubtful Siri will ever grace Android or BlackBerry."

HP Compra a Palm



Depois da Palm ter demorado em vingar com o Palm Pre e o WebOS e estar no mercado à venda a um tempo, a HP estar em campanha competindo com o iPad com o produto ainda a lançar, o HP Slate, a HP anunciou a compra da Palm para dar um gás nessa competição.

Segue trecho da notícia e link:

HP buys Palm -- Engadget: "HP has just announced that it's acquiring Palm to the tune of $1.2 billion, which works out to $5.70 per share of Palm common stock. The deal is planned to close by July 31, which marks the end of HP's third fiscal quarter of the year. Current Palm CEO Jon Rubinstein is 'expected to remain with the company,' though it's not said in what capacity. Press release after the break. There'll be a call to discuss the acquisition in more detail (well, we hope in more detail) at 5PM ET, so we'll keep you abreast as we learn more.

Update: PreCentral's managed to grab a copy of Rubinstein's letter to Palm employees."

Portando aplicações do iPhone para netbooks

Artigo discute como dois programadores utilizam técnicas diferentes para portar aplicações móveis do iPhone para netbooks.

Trecho e link da notícia:

A Tale of Two Ports: A Picard vs Kirk review of mobile app porting techniques | Intel� Atom™ Developer Program: "I had the pleasure this last month collaborating with two accomplished developers on their methods for porting iPhone games to AppUp for netbooks running Windows. I was very impressed by the creativity, ingenuity of these ports while at the same time it appears they follow some common practices to ensure quality a experience on a netbook. While very different these porting methods are both viable and I believe represent the most likely scenarios for porting a mobile app to AppUp."

Gizmodo: Why I've Replaced My iPhone's Music App With SoundHound - Soundhound - Gizmodo

Why I've Replaced My iPhone's Music App With SoundHound

Why I've Replaced My iPhone's Music App With SoundHound - Soundhound - Gizmodo: "Remember Midomi? It was a first-wave iPhone app that identified songs, hummed or recorded, via microphone. It's since grown into a much more ambitious app called SoundHound—ambitious enough to actually replace your iPhone's music app. Now, it's free.

SoundHound's music recognition feature is still prominently featured, and it still does its job. Unlike Shazam, it will hazard a guess at just about any tune thrown at it, whether it human or speaker-created, and it'll succeed most of the time. Quick tests from my music library had both Shazam and SoundHound correctly identifying the track, though SoundHound, which evaluates whether or not to submit the track to its servers at a series of intervals, rather than after single, set period, was often faster. Shazam's catalog did seem a bit deeper for more obscure tracks. But that's nothing new, really."

iPhone is Most Popular Phone for Opera Mini Downloads in USI

iPhone is Most Popular Phone for Opera Mini Downloads in US - Opera mini iphone - Gizmodo: "In just 16 days, it's soared up the charts with over a million downloads on the first day of availability. Now, the iPhone version is the third most popular for Opera Mini downloads worldwide, and number one in the US.

The figures come via Opera's State of the Mobile Web report, which shows how they've taken over BlackBerry's top spot for US phone downloads. Worldwide however, the iPhone still needs to take on Nokia and Sony Ericsson handsets, with Opera saying the top 20 list was dominated by these two manufacturers. [Opera via TechCrunch]"

iTuner: Companheiro completo pro iTunes

iTuner é um software gratuito para Windows que mostra o que está tocando no iTunes, pega a letra da música, exporta playlist, organiza arquivos e sincroniza com seu dispositivo USB, mesmo que não seja um iPhone ou iPod ou qualquer outro produto da Apple.

Segue abaixo trecho da notícia e link:

iTuner Is the One iTunes Helper to Rule Them All - iTunes - Lifehacker: "Windows: If you're an iTunes user with a bunch of helper programs to show what's playing, grab lyrics, export playlists, organize files, and sync with your USB device, you might be able to do it all at once with free utility iTuner.

We've featured no shortage of iTunes helpers and mini-players, from previously mentioned SkiniTunes to moreTunes to CD Art Display. Many of these have a few other features too, but their feature completeness cannot compare with iTuner, which can maintain your library (by removing dead/duplicate tracks and empty directories), sync your library or playlists with a non-iPod MP3 player, set global hotkeys, export playlists, convert tracks, and automatically fetch lyrics all while sitting in your system tray. And of course, it contains all the usual mini-player features—switching tracks, now-playing functionality, rating songs, and adjusting volume, except it stays out of your way unless you invoke it with its keyboard shortcut so it doesn't take up any screen real estate (which can be nice, or can be super annoying if you'd prefer it stay on screen since there's no way to do that)."

Apple - iPad-ready websites

Apple divulga uma página com sites que estão prontos com o iPad, a Apple segue todos os padrões abertos para navegação web móvel, e como Flash é um padrão fechado, ficou de fora.

Apple - iPad-ready websites: "Ready for iPad.

iPad features Safari, a mobile web browser that supports the latest web standards — including HTML5, CSS3, and JavaScript. Here are just a few of the sites that take advantage of these web standards to deliver content that looks and functions beautifully on iPad."

Um mundo sem Flash

Pois é, o Facebook agora está adicionando suporte à videos com HTML5 ao invés de Flash.
A briga entre a Adobe e a Apple por conta do Flash para iPhone e iPad pelo jeito está tomando um rumo a favor do HTML5.

Facebook Adds HTML5 Support to Videos - PCWorld: "Sorry, Flash, but it looks like yet another Website is petitioning to join Apple's 'iPad Ready' clique. On Tuesday, MacStories discovered that Facebook is converting its newest videos into HTML5 for easy iPad/iPhone viewing.

Currently, users who wish to show off their video creations on Facebook have two options: embed via YouTube, or upload to Facebook directly. Until now, iPhone and iPad users could only view linked YouTube clips; Facebook video would present the all-too-familiar 'Flash Player upgrade required' when tapped."

A Month With the IPad: Surprises and Disappointments - PCWorld

Uma reportagem sobre 1 mês de uso do iPad, ponderandos as coisas boas e ruins.

Coisas boas:
* Interface super natural de utilizar
* Qualidade da saída de som
* Tamanho realmente faz diferença
* Ótimo para jogos
* Travar a orientação para não ficar rotacionando
* Utilização de teclado externo

Coisas ruins:
* Não existem contas, todos utilizam o mesmo perfil
* Aproveitamento ruim da Home Screen com a tela do iPad
* Navegação com 9 páginas no Safari pode deixar o iPad lento, principalmente por ter aumentado consideravelmente quantidade de videos e imagens que ficam na tela do iPad comparado com o iPhone
* Pesando pouco mais de 500g realmente o iPad é muito mais leve que um laptop, mas também por outro lado, ninguém trabalha segurando um laptop na mão
* O iPad é fino.. e também escorregadio
* A tela do iPad é bem brilhante, porém nem sempre é mais brilhante que o brilho do reflexo da tela


A Month With the IPad: Surprises and Disappointments - PCWorld: "Given the amount of hype that preceded the iPad's release, it's hard to believe that it would bear any great surprises not touted by Apple or that it could possibly live up to expectations. Still, when we unpacked our iPads on April 3 and used them over the next three weeks, we found unexpected delights as well as features that made us go 'Hmm….'

With the Wi-Fi iPad approaching its first month on the market-and the 3G-enabled models set to arrive at the end of this week-here's a rundown of what surprised and disappointed us with Apple's latest mobile device."

Lançamento Nokia N8
