Satpam JW Marriott Sempat Menyapa pelaku bom Bunuh Diri di hotel JW Marriott

Salah seorang satpam yang juga menjadi korban bom JW Marriott, Dikdik Ahmad Taufik, mengaku sempat menegur seorang pria yang diduga kuat sebagai pengebom bunuh diri.

Saat ditemui di Rumah Sakit Jakarta, Dikdik yang menjabat supervisor security di Marriott menuturkan, pada Jumat (17/7) pagi, dirinya sempat bertemu dengan seorang pria bertopi yang membawa tas dan menyeret koper.

"Saya sempat lihat, sempat ketemu. Saya tegur orang itu sekitar pukul 7.00 pagi lebih lah. Saya sapa dia, 'pagi pak, bisa dibantu', " tutur Dikdik, ketika ditemui di RS Jakarta, Sabtu ( 18/7 ). Menurut Dikdik, pria tersebut sempat menjawab, "Ya saya mau ketemu bos saya". Dikdik kemudian menimpali pertanyaan, "Yang mana, siapa?". Pertanyaan tersebut kembali dijawab oleh pelaku. "Ini, saya mau kasih pesanan".

Berdasarkan penuturan Dikdik, pria itu membawa koper dan tas. Dengan ciri-ciri, warga negara Indonesia, kulit berwarna sawo matang, muka bersih tanpa jenggot, tinggi sekitar 172 cm, dan usia sekitar 25 atau 28 tahun.

"Tingginya sekitar saya lah. Saya tidak ada feeling sama sekali, tidak ada firasat karena sudah di dalam. Karena kan pelakunya sudah di dalam dan sudah melewati metal detector," ujarnya.

Setelah bertemu dengan pelaku, lanjut Dikdik, dirinya langsung berbalik menuju lobi. Tidak lama berselang, terdengar bom meledak. "Kira-kira satu menit, langsung duarr," ceritanya.

Akibat kejadian tersebut, Dikdik terpaksa dirawat di kamar 359 RS Jakarta karena menderita luka bakar di bawah telinga kanan, dan excoriasi kaki, muka, dan tangan.

Manchester United Batal ke Indonesia dan Akan Mencari Negara Pengganti

Rooney MU Batal ke Indonesia, MU Akan Mencari Negara Pengganti Batalnya tur Manchester United di Jakarta tinggal menunggu pengumuman resminya saja. Ketua promotor LOC Agum Gumelar melalui SMS-nya mengindikasikan pembatalan tersebut.

Hal itu dikatakan manajer timnas Indonesia Andi Darussalam kepada wartawan di kantor PSSI kompleks Stadion Gelora Bung Karno, Senayan, Jakarta, Jumat (17/7/2009) siang, menyusul pengeboman Hotel Ritz Carlton tadi pagi.

Dikatakan Andi, dirinya menerima pesan singkat dari Ketua Bidang Pertandingan MU versus Indonesia All Star, Djoko Driyono, yang meneruskan informasi dari Agum Gumelar.

Dikatakan bahwa Agum telah berteleponan dengan Kaba Intelkam Mabes Polri, Irjen Pol. Saleh Saaf, yang mengatakan bahwa pertandingan MU batal. “Tapi mereka (LOC) masih menunggu keputusan resmi dari pemerintah,” ungkap Andi yang juga direktur Badan Liga Indonesia itu.

Manchester United akan mencari negara lain untuk disinggahi setelah dipastikan batal mengunjungi Indonesia dalam rangkaian tur Asia 2009. Negara mana yang beruntung?

Indonesia adalah negara kedua yang rencananya akan dikunjungi MU dalam rangkaian tur Asia 2009. “Setan Merah” pertama akan mengunjungi Malaysia, setelah ke Jakarta, anak asuh Sir Alex Ferguson akan berlanjut ke Korea Selatan dan Cina.

Menyusul kepastian batal mengunjungi Jakarta, agenda MU untuk tanggal 18 hingga 21 Juli dipastikan kosong. Namun menurut pernyataan resmi klub juara Liga Inggris tersebut, mereka saat ini tengah menjajaki mengunjungi negara lain menggantikan Indonesia.

“Saat ini kami sedang mengupayakan untuk melakukan perjalanan alternatif di luar Indonesia. Kami akan membuat pengumuman lebih lanjut saat keputusan tersebut sudah dibuat,” demikian pernyataan resmi kubu The Red Devils seperti diberitakan Telegraph.

Sebelumnya sempat beredar kabar kalau MU akan membatalkan seluruh kegiatan tur Asia 2009 lantaran pemain yang membawa keluarga dikhawatirkan akan mengalami depresi. Namun dengan pernyataan terbaru ini dipastikan kalau pasukan “Setan Merah” masih akan melanjutkan rangkaian tur Asia tersebut.

performance remains an uphill battle

Firefox 3.5 has arrived, and according to Mozilla Foundation developers, its major advantage is speed. The new version of the open source Web browser is the first generally available release to include the TraceMonkey accelerated JavaScript engine, which previously had been found only in the 3.1 betas.

This move is the latest volley in the rejuvenated browser wars, as browser vendors shift their focus toward improving the performance of Web-based applications. Google set the pace when it shipped Chrome with a high-performance JavaScript engine last year. Since then, Opera and Apple have both announced new JavaScript engines for their respective browsers, and even Microsoft has grudgingly worked to optimize IE8.

[ See also: Google seeks faster Web | Keep up with app dev issues and trends. Check out InfoWorld's Developer World channel and Fatal Exception and Strategic Developer blogs. ]

But browser performance isn't everything. Users experienced delays browsing major news sites in the wake of the death of pop star Michael Jackson last week, but the problem there wasn't slow browsers or even overloaded servers. According to Web monitoring company Keynote Systems, in many cases site slowdowns were caused by ad networks and other third-party content providers, whose own networks couldn't handle the increased traffic.

This incident underscores an issue of growing concern to Web developers. Modern Web apps typically draw from multiple content sources, data stores, and services, and growing interest in cloud computing will only accelerate this trend. But given all these interdependencies, can Web developers really guarantee fast, responsive user experiences? Or as the complexity of our applications continues to grow, is application performance gradually slipping out of our fingers? Are we all just throwing ourselves on the mercy of the Internet?

Web developers' cloud conundrum
Making Web pages is easy, but building efficient Web applications can be deceptively tricky. Desktop software is tangible; as a developer, you can get your hands around it. To optimize its performance, you do things like eliminating memory leaks and improving the efficiency of disk access. None of this applies to Web apps, however, where developers rely on browsers to handle local resources efficiently.

Instead, Web developers are confronted with the vagaries of the network. If a user accesses a Web page that draws images from a third-party provider, the overall user experience depends on the user's browser, the user's data connection, the outgoing pipe from the Web server, the Web application software, the pipe between the Web server and the image provider, and the image provider's server software. A Web application developer is in a position to optimize only one of these.

Consider what else developers take for granted in this distributed, cloud-based model. How can you be sure that the third-party image provider takes security seriously? How can you be sure that its systems are sufficiently redundant, and that it makes backups regularly, so you won't be blindsided by any unexpected outage? You can ask, of course.

A more immediate problem lies in the ways in which external services integrate with Web pages. Most of them rely on external JavaScript, iframes, or both. Either of these techniques can block a page's onLoad event, a major factor in the user's perception site slowness. This bottleneck happens before the JavaScript code executes, so the speed of the browser's JavaScript engine makes little difference. Combine this design with an overburdened network, and it's not just third-party content but your entire application that suffers.

Increased complexity leads to increased risk for Web apps
The Web community is working on ways to mitigate these problems. For example, modern browsers load other content elements while they're waiting for JavaScript to execute, and developers have come up with various clever techniques to eliminate script bottlenecks. But these one-sided optimizations can only get you so far, and they're difficult to do right.

"Think about it," says Steve Souter, a performance evangelist at Google and author of the books "High Performance Web Sites" and "Even Faster Web Sites." He adds, "We're taking a chunk of HTML that might also include CSS, JavaScript, and Flash, and stuffing it into another page ... It's not surprising that they can, and do, significantly degrade the performance of Web pages, and in some cases can cause a Web site to fail entirely."

Part of the problem lies in the fact that such content-integration efforts often lack cohesive management and oversight. "Integrating third-party content into a Web page would be a complex project to pull off for two teams working in the same company," Souter says. "In the case of ads, the two teams work at two different companies. In fact, the developers creating the ad probably never interact with the team building the main Web site."

That's not to say that everyone will share the responsibility for site slowdowns, however. Rest assured that when site performance degrades, the user will place the blame squarely on the site's own brand: The external content providers will remain virtually anonymous.

Baby steps toward the Web as a first-class app platform
For now, Web application developers and architects should be sure to educate themselves about the potential bottlenecks and other pitfalls inherent in distributed, cloud-like Web applications. Souter's books are a good place to start, and Google has recently launched a Web site dedicated to developing best practices for JavaScript performance.

In the long run, however, Web services providers and consumers will need to work together to develop standards of practice for the cloud-based Internet. The Interactive Advertising Bureau has formed a working group and offers best practices for ad providers to improve load times. This is a good start, but clearly there's still much more work to be done.

One of the more troubling aspects of the current situation is that it tends to favor larger customers. Wal-Mart or a major sports league might be in a position to demand comprehensive SLAs and developer accountability of their external content providers, but a struggling newspaper publisher might not -- to say nothing of even smaller clients.

That's why it's of critical importance that the Web community work to increase not just browser performance, but the performance of cross-organizational Web development teams. As sites and services become increasingly interconnected, we need to come up with new ways to communicate, collaborate, and cooperate to make distributed, cross-site development efforts run more smoothly. Only in this way will the cloud-based Web flourish into a reliable, first-class application development platform.

Microsoft Silverlight 3 unveiled

Seeking an edge in the crowded rich Internet application technology space, Microsoft on Friday officially launched its Silverlight 3 platform, championing the technology at a launch event in San Francisco that also featured partners such as NBC Sports and Continental Airlines.

The plug-in technology features offline capabilities for running applications outside of a browser, as well as 3-D capabilities and advanced streaming via Smooth Streaming, in which a Silverlight client is paired with Microsoft's Internet Information Services on the back end.

[ Yesterday, Microsoft and IBM discussed software development advances. ]

The company also launched its Expression 3 platform for application design, featuring the Expression Studio 3 suite of tools. Silverlight and its accompanying software development kit actually were made available earlier this week, while Expression 3 tools ship within 30 days.

"We've got more than 300 partners delivering Silverlight applications today," said S. "Soma" Somasegar, senior vice president of the Microsoft developer division. "This is the fastest-growing plugin ever." Silverlight initially launched in September 2007.

NBC Sports, which has used Silverlight in the 2008 Olympics, announced intentions to use Silverlight for online video delivery across its sporting franchises, including the 2010 Winter Olympic Games in Vancouver. Microsoft had streamed content via Silverlight at the Beijing Olympics last year.

"In these 22 months [since the technology's introduction], Silverlight is enabling NBC Sports to go ahead and deliver full, HD broadcast-quality video to our users and our advertisers," said Eric Black, of NBC Sports.

Silverlight, though, must compete with the more established Adobe Flash platform, as well as with Sun Microsystems JavaFX technology. Complicating this field are HTML technologies that could eventually eliminate the need for plug-ins such as Silverlight, Flash, and JavaFX.

With Silverlight and Flash leading the field, competition between the two is "getting to be like Honda and Toyota," said analyst Ray Valdes, vice president of Web services at garnter.

"I think the key difference is the .Net compatibility and alignment [for Silverlight] and that will be a positive for some and a negative for others," Valdes said.

Microsoft said adoption of Silverlight has accelerated, with more than one in three Internet devices having installed the earlier Silverlight 2 release since its release about nine months ago. Silverlight customers being announced on Friday included the MGM "SGU: Stargate Universe" TV show and Continental Airlines, which plans to use Silverlight in a call center reservation system. MGM will allow Web users to zoom in on parts of a new show set via a Deep Zoom capability introduced in Silverlight 2.

Silverlight is a free runtime; monetizing it involves selling related products such as the Expression line and Windows Server. Microsoft is offering its Visual Studio Professional Edition and Expression Studio 3 together for $999. Featured in the Studio package is SketchFlow, for rapid prototyping of applications. SketchFlow presents "the idea that you can actually start a project without knowing what the final bits are going to look like," said Scott Guthrie, corporate vice president of the .Net develoiper platform at Microsoft. SketchFlow is an interactive tool that can incorporate pen and paper sketches.

Expression 3 features the $599 Expression Studio 3 suite, with tools including Expression Blend, for interactive design and including SketchFlow; Expression Web, for Web design and supporting CSS and the soon-to-be-discontinued XHTML standard; Expression Encoder, for video encoding; and Expression Design, for illustration and design.

Cloud computing made real

Chrome OS must be a dream come true for Google-versus-Microsoft fanboys. Rumors that Google would ship a desktop OS first flew back in 2006, but the project in question turned out to be for internal use only. Then came Android, and reports that Google's smartphone OS would soon make the leap to more traditional PCs set the market abuzz again -- although many remained skeptical. Now the announcement of Chrome OS should brush any lingering doubts aside.

Not everyone is impressed with the search giant's latest move, however. My colleague Randall Kennedy says Chrome OS has "an ice cube's chance in Hell" of competing successfully with Windows or Mac OS X, citing the overwhelming effort needed to duplicate the full range of device drivers and applications available on those platforms today. Randall just doesn't see that happening, and for that matter neither do I.

[ Find out what InfoWorld contributors Randall Kennedy and Savio Rodrigues think of Google's newly announced OS ]

But Chrome OS isn't meant to be a pound-for-pound competitor to Windows. Though it's built on the Linux kernel, it's really something brand new. In fact, when we look back 10 years from now, the debut of Google's Chrome OS may well mark the moment when cloud computing finally became real.

Chrome OS: Custom-built for the cloud
It's particularly telling that Chrome OS will ship with support for both Intel and ARM processors. Google reps say the OS will initially target netbooks, and low-powered ARM chips are expected to play an increasing role in that market.

Even more interesting, however, is the revelation that the heart of the Chrome OS user experience is Google's Chrome browser -- and that booting a Chrome OS device should get you "onto the Web in seconds," according to the search giant's press release. In fact, the browser may be the only traditional application that runs on Chrome OS. Quoth the release: "For application developers, the Web is the platform" (emphasis mine).

This sounds an awful lot like the type of device I've talked about before, which I've dubbed "the Invisible PC." Rather than the traditional desktop model of applications running on a monolithic OS, in this new mode of computing the PC will all but disappear, leaving little more than a window to the Web. Desktop applications will be replaced by Web-based services, with computation and storage handled in the cloud.

It's fair to be skeptical, but don't underestimate the extent to which Web applications have already supplanted desktop software. Enterprises have been slow to adopt Web-based alternatives (and with good reason), but individual users have embraced them wholeheartedly. Remember when you had to install a special client program to read your e-mail? My mom doesn't. To her, e-mail is synonymous with Web-based services such as Gmail, MSN, and Yahoo Mail. Expect more categories of applications to go this way as Web technologies continue to mature.

Google isn't alone in pursuing the Invisible PC market, either. You could argue that devices like Nokia's Internet Tablet and the iPod Touch were the pioneers in this category, and Palm's WebOS shares Google's philosophy of Web-based application development. But Chrome OS promises a number of advantages that make it an ideal fit for today's lightweight netbooks and beyond.

The engine beneath the Chrome
For starters, Chrome is arguably the most technologically advanced browser in the world. Its multiprocess design, where each session exists independently from the others, more closely resembles a traditional OS than it does any other current browser, and its security model can't be beat. What's more, Chrome includes support for Google Gears, which gives it an advantage when Internet access is spotty.

As I mentioned before, Chrome OS runs on a Linux kernel, but that will hardly be relevant to application developers. Apps will be Web-based, but because the Chrome browser was designed with desktop PCs in mind, developers won't be limited to the stripped-down capabilities available in most smartphones and other devices. Google is one of the biggest advocates of the forthcoming HTML 5 specification, portions of which have already made their way into current-generation browsers, including Chrome. (And if you want to get an idea of the kind of applications made possible by HTML 5, look no further than Mozilla Bespin.)

Because Chrome OS is based on the open source Linux kernel, however -- and Google plans to open source the higher-level bits later this year -- the community will be free to lend a hand patching bugs and fixing security vulnerabilities as they appear.

Death to the desktop?
And there's more. Between the kernel and the Chrome interface, Google says it has developed "a new window manager" to handle rendering the GUI. Details are still scant, but from the sound of it, Google has opted to skip Gnome and KDE, and possibly even toss out the venerable X Window Manager itself. If so, Chrome OS is definitely not just another desktop Linux distro. In fact, it might not even qualify as a desktop OS at all.

How so? Consider how bloated mainstream desktops have become over the years. Whether your choice is Linux, Mac OS X, or Windows, your desktop greets you with countless menus, configuration panels, and applications, ranging from simple Internet clients to full-blown multimedia suites. Google's vision is different. "Google Chrome OS," Google's press release explains, "is being created for people who spend most of their time on the Web." If that's the case, then an old-style desktop is total overkill.

If your applications are Web-based, you don't need a software installer. Similarly, if all your data is stored in the cloud, the need for a full-featured file manager diminishes significantly, and you certainly won't need one of those fancy desktop search engines that are so much in vogue lately. You also won't need a backup manager, a disk defragmenter, a virus scanner, or a file-compression program. In fact, you probably don't need a desktop at all. What you'd really want is a lean, fast, responsive, simple UI -- something like you'd expect in a consumer electronics device -- and if Google is thinking like I'm thinking, expect Chrome OS to deliver just that.

Of course, we won't know what Chrome OS is really like until more details emerge later this year. But if it really is all that I think it could be, Chrome OS will bring changes to the PC market that have been a long time coming. We have a name for that: evolution.

But Chrome OS isn't meant to be a pound-for-pound competitor to Windows. Though it's built on the Linux kernel, it's really something brand new. In fact, when we look back 10 years from now, the debut of Google's Chrome OS may well mark the moment when cloud computing finally became real.

Chrome OS: Custom-built for the cloud
It's particularly telling that Chrome OS will ship with support for both Intel and ARM processors. Google reps say the OS will initially target netbooks, and low-powered ARM chips are expected to play an increasing role in that market.

Even more interesting, however, is the revelation that the heart of the Chrome OS user experience is Google's Chrome browser -- and that booting a Chrome OS device should get you "onto the Web in seconds," according to the search giant's press release. In fact, the browser may be the only traditional application that runs on Chrome OS. Quoth the release: "For application developers, the Web is the platform" (emphasis mine).

This sounds an awful lot like the type of device I've talked about before, which I've dubbed "the Invisible PC." Rather than the traditional desktop model of applications running on a monolithic OS, in this new mode of computing the PC will all but disappear, leaving little more than a window to the Web. Desktop applications will be replaced by Web-based services, with computation and storage handled in the cloud.

It's fair to be skeptical, but don't underestimate the extent to which Web applications have already supplanted desktop software. Enterprises have been slow to adopt Web-based alternatives (and with good reason), but individual users have embraced them wholeheartedly. Remember when you had to install a special client program to read your e-mail? My mom doesn't. To her, e-mail is synonymous with Web-based services such as Gmail, MSN, and Yahoo Mail. Expect more categories of applications to go this way as Web technologies continue to mature.

Google isn't alone in pursuing the Invisible PC market, either. You could argue that devices like Nokia's Internet Tablet and the iPod Touch were the pioneers in this category, and Palm's WebOS shares Google's philosophy of Web-based application development. But Chrome OS promises a number of advantages that make it an ideal fit for today's lightweight netbooks and beyond.

The engine beneath the Chrome
For starters, Chrome is arguably the most technologically advanced browser in the world. Its multiprocess design, where each session exists independently from the others, more closely resembles a traditional OS than it does any other current browser, and its security model can't be beat. What's more, Chrome includes support for Google Gears, which gives it an advantage when Internet access is spotty.

As I mentioned before, Chrome OS runs on a Linux kernel, but that will hardly be relevant to application developers. Apps will be Web-based, but because the Chrome browser was designed with desktop PCs in mind, developers won't be limited to the stripped-down capabilities available in most smartphones and other devices. Google is one of the biggest advocates of the forthcoming HTML 5 specification, portions of which have already made their way into current-generation browsers, including Chrome. (And if you want to get an idea of the kind of applications made possible by HTML 5, look no further than Mozilla Bespin.)

Because Chrome OS is based on the open source Linux kernel, however -- and Google plans to open source the higher-level bits later this year -- the community will be free to lend a hand patching bugs and fixing security vulnerabilities as they appear.

Death to the desktop?
And there's more. Between the kernel and the Chrome interface, Google says it has developed "a new window manager" to handle rendering the GUI. Details are still scant, but from the sound of it, Google has opted to skip Gnome and KDE, and possibly even toss out the venerable X Window Manager itself. If so, Chrome OS is definitely not just another desktop Linux distro. In fact, it might not even qualify as a desktop OS at all.

How so? Consider how bloated mainstream desktops have become over the years. Whether your choice is Linux, Mac OS X, or Windows, your desktop greets you with countless menus, configuration panels, and applications, ranging from simple Internet clients to full-blown multimedia suites. Google's vision is different. "Google Chrome OS," Google's press release explains, "is being created for people who spend most of their time on the Web." If that's the case, then an old-style desktop is total overkill.

If your applications are Web-based, you don't need a software installer. Similarly, if all your data is stored in the cloud, the need for a full-featured file manager diminishes significantly, and you certainly won't need one of those fancy desktop search engines that are so much in vogue lately. You also won't need a backup manager, a disk defragmenter, a virus scanner, or a file-compression program. In fact, you probably don't need a desktop at all. What you'd really want is a lean, fast, responsive, simple UI -- something like you'd expect in a consumer electronics device -- and if Google is thinking like I'm thinking, expect Chrome OS to deliver just that.

Of course, we won't know what Chrome OS is really like until more details emerge later this year. But if it really is all that I think it could be, Chrome OS will bring changes to the PC market that have been a long time coming. We have a name for that: evolution.
