Gmail Improves "Undo Send"

Gmail has a very useful Labs feature called "undo send" that lets you "unsend" a message immediately after sending it. If you accidentally clicked on the "Send" button or you realize that you forgot to attach an important file, you have a few seconds to click on "undo" and continue to edit the message.


When Gmail launched this feature, you only had 5 seconds to undo sending a message, but Google constantly added new periods: 10 seconds, 20 seconds and now 30 seconds. You can change the "send cancellation period" from the settings page.


Probably a better idea would be to add an outbox, so that you can set a longer delay. Another benefit would be that you could also schedule sending an email message.

Google Chrome's PDF Plugin Uses Foxit Software

Google Chrome's built-in PDF plugin uses Foxit PDF SDK. As you can see from this page, there are many references to Foxit's SDK, which is a proprietary set of tools that allow applications to read or modify PDF files.


"With the incredible small size (less than 2MB) and amazingly fast speed, Foxit PDF SDK (DLL) 2.0 is your absolute choice to develop your own PDF applications," suggests Foxit.

Google decided to include two of the most popular plugins (Flash and PDF) in Google Chrome to make the browser more secure. The PDF plugin runs inside Chrome's sandbox so that vulnerabilities can no longer install malware on your computer. The Flash plugin is automatically updated by Google and it's likely that it will run inside Chrome's sandbox in the future. Google Chrome 5 already includes the Flash plugin, while the PDF plugin is available in Google Chrome 6 (dev, beta and soon in the stable channel).

Google Live Search: See Search Results as You Type

Google tests a new search interface that updates the results as you type a query. In this experiment, you never have to press Enter or click on the "Search" button to see the results because Google constantly retrieves the results for your query.

While this interface has the advantage that you can refine your search faster, the constant refreshing can be annoying if you don't need help. Rob Ousbey calls this experiment "live updating Google search results", Google uses the word "streaming", while others may call it instant search or incremental search. Google probably wants to morph the search box into a query builder with instant preview.


Check the HD version of the video to better see Google's new UI.

The experiment is not available in Google Labs, but you can try a similar interface at Google Alerts. Type some keywords, click on "preview results" and every time you change the search terms, Google Alerts shows a preview. There's also Keyboardr, a site that uses Google AJAX API to shows results as you type.

Update: Another user noticed the changes. When you visit Google's homepage and start typing your query, Google moves the search box at the top of the page and displays the results. "Open the Google page and start typing. Previously, the screen didn't shift. Now, though, as soon as you start typing, Google shifts the search box to the top of the page, and displays ads to the right and distracting search results below." The new UI can be disabled by clicking on "turn off streaming" next to the search box.

Google Buys Like.com (and Riya, Too)


Google acquired Like.com, a product search engine that used visual search to find similar products. "We were the first to bring visual search to shopping, the first to build an automated cross-matching system for clothing, and more," says Munjal Shah, the former CEO of Riya, the company that developed Like.com.

Riya launched in 2005 an impressive software that used face recognition to organize photos. "Riya leveraged facial and text recognition technology with an intelligent interface to help people make sense of the thousands of untitled and untagged photos that are building up on their hard drives." Google launched a similar service 4 years later, using technology from Neven Vision.


Much like Google Wave, Riya's software looked great in demos, but it didn't work well in the real world. The software required a huge collection of photos and each photo had to be uploaded to Riya's servers. "The process is slow; Riya says it takes about 24 hours to upload 4,000 pictures," mentioned the USA Today at that time.

Apparently, Google intended to buy Riya in 2005, but decided to acquire Neven Vision, a company that had a lot of patents on face recognition, photo analysis, visual mobile search. Neven Vision's acquisition helped Google add face recognition to Picasa, advanced features to Google Image Search and visual search to Android.

Why would Google acquire Riya? Probably because the company has many patents on visual recognition and a lot of talented engineers that could work on bigger projects than Like.com. In 2006, Riya planned to launch a visual search engine with support for object recognition, but the company didn't find a way to monetize the product, so it focused on product search, which was more lucrative. Now the team can finally build Riya 2.0:

Google Tests a New Interface for Google Translate

Garrid Lou spotted a new user interface for Google Translate, which shows examples of news sites that can be translated and other Google products that use Google Translate. The new interface replaces the long drop-down of languages with a multi-column list and moves the translated text to the right.

Google's Implicit Site Searches

Malcolm Coles spotted an interesting change in Google's ranking algorithms. If your query includes the name of a company, an organization or any name associated with a website, many of the top search results are pages from that site. For example, a search for [apple ipod] returns 7 pages from apple.com on the first page of results.


Google confirmed this change: "We periodically reassess our ranking and UI choices, and today we made a change to allow a larger number of pages from the same site to appear for a given query. This happens for searches that indicate a strong user interest in a particular domain."

Bill Slawski found a Google patent about detecting entities from queries and performing implicit site searches. "A system receives a search query, determines whether the received search query includes an entity name, and determines whether the entity name is associated with a common word or phrase. (...) When the entity name is not associated with a common word or phrase, the system rewrites the received search query to include a restrict identifier associated with the entity name, generates a link to the received search query, performs a search based on the rewritten search query to obtain second search results, and provides the second search results and the link to the received search query."

When you search for [apple ipod], Google detects the entity [apple], finds that it's associated with www.apple.com and adds some results for the query [ipod site:apple.com].

Search engines limit the number of search results from a domain to 2 or 3 pages that are usually grouped. The goal is to show diverse results and to prevent websites from dominating the first page of results. Showing too many results from Apple's official site when searching for [apple ipod] is not a good thing because some people might want to read reviews, historical information from Wikipedia, news articles.

Sergey Brin said in an interview from 2004 that it's important to diversify search results:

"I agree that diversity of sources is a desirable goal, and in fact the results naturally tend to be diverse. We do some simple things to increase the diversity. If you check almost any topic, you will get diverging viewpoints. Everyone on any side of an issue will typically complain, though. Environmentalists will say,'Why aren't you showing our results first?' An industrial group will say, 'Why aren't you showing our results first?' They all want to be number one. We think it's good for us to encourage diverse viewpoints, and the search engine presents them. It happens naturally as a response to queries."

The change is useful for queries like [dicaprio imdb], [michael nyman wikipedia], where imdb and wikipedia are shortcuts for site:imdb.com and site:wikipedia.org.

Gmail Voice and Video Chat for Linux

After two years of waiting, Gmail's plug-in for voice and video chat is finally available for Linux users. "Voice and video chat for Linux supports Ubuntu and other Debian-based Linux distributions, and RPM support will be coming soon," says Tristan Schmelcher, from Google.


Justin Uberti says that adding Linux support was really difficult. "This release required significant engineering to develop an all-new video rendering solution and an all-new PulseAudio-based audio handler, along with work to support 64-bit and countless webcam compatibility tests. We spent a lot of effort to make it fully feature-complete, with all the same goodies as the Windows and Mac versions, and we're happy to now support Google voice and video now on all major desktop platforms."

Now that video chat is available on Windows, Mac and Linux, when will it be ported to Android?

Contoh Binary Search dalam C++

"Om Swastiastu"

Binary search, atau metode pencarian secara biner hanya bisa dilakukan jika data sudah terurut. Keunggulan dari proses binary search ini adalah sistem pencariannya yang relatif cepat dan efisien walaupun ada banyak data sekalipun. Karena data dicari dari depan, tengah dan belakang. Tetapi sintaks dan algoritmanya sedikit lebih rumit, karena kita harus mengurutkan data terlebih dahulu. Pengurutan data disini bisa kalian lakukan dengan metode ascending ataupun descending.

Untuk dasar dari binary search ini, saya akan memberikan array dengan data yang telah diurut sebelumnya. Agar lebih mudah memahami dasar dari binary search ini. Adapun algoritma dari binary search ini adalah sebagai berikut.

  • Membaca data yang ada di array
  • Jika data belum terurut, maka lakukan pengurutan data
  • Menentukan data yang akan dicari di dalam array
  • Menentukan nilai elemen tengah array
  • Jika nilai elemen tengah array sama dengan data yang dicari, maka pencarian akan dihentikan
  • Jika elemen tengah tidak sama dengan data yang dicari, maka:
    • Jika nilai tengah lebih besar dari nilai yang dicari, maka pencarian hanya dilakukan pada setengah array pertama
    • Jika nilai tengah lebih kecil dari nilai yang dicari, maka pencarian hanya dilakukan pada setengah array sisa.

On Gmail's Widget for Selecting Messages

Gmail updated the interface last week and many people complained about the changes. Some didn't like Gmail's new hybrid button for selecting messages. To select unread messages or starred messages, you need an extra click. Apparently, many Google employees hated this change, as well.


Michael Leggett, Gmail's lead user interface designer, explains how he came up with this widget:
It IS odd. And yet, both the checkbox and the menu part tested very well in the lab. The people who hated the widget outside the lab also understood how to use it but promised others wouldn't b/c it was so "weird."

We tried a few things (like putting the select actions under "More actions") but I didn't have high hopes for any of them except the widget that launched. It tested better than I had hoped (all of the participants in the usability study were able to select all, unread, and none). We launched it to all Googlers months ago and listened to feedback (everyone was able to figure it out... some just hated the change).

More about why the change: The "Select all" link is used by <1% style="font-weight:bold;">I wanted to simplify the interface and give back that space to users.

Since features like "select unread" or "select starred" were used by a lot less than 1% of the users, it made sense to hide them. Power users can always learn how to use keyboard shortcuts and an extra click doesn't mean too much for a feature that's rarely used.

Michael Leggett also says that the link to Buzz will be added at the top of the page, next to Contacts and Tasks, and users will be able to hide the links to service they don't use.

Google Spreadsheets Spell Checking

Google Spreadsheets added spell checking, but it doesn't find misspellings automatically, like in Google's word processor. You need to click on the Tools menu and select Check spelling. Google starts to find mistakes and suggests corrections from the dictionary. Unfortunately, you can't add words to the dictionary yet and Google's suggestions are sometimes terrible.

"The tool will go through all the cells on your sheet, highlighting each cell which has a misspelled word in red. Words that might be misspelled in each cell are underlined in red and can be changed by clicking on them and selecting the right spelling," explains Google Docs blog.


Google should replace the dictionary-based spell checker with the context-sensitive spell checker that's already used in Google Wave and Google Search. Instead of using a dictionary, this spell checker extracts data from web pages and Google searches to find a statistical language model, much like Google Translate. This model allows Google to predict mistakes and to determine the most likely corrections.

Gmail's New Bug Reporting Interface

Go to Gmail and click on the "Report a bug" link at the top of the page. You might see a completely different interface that looks just like the Google Feedback extension tested in March. The main difference is that it works in almost any browser and you don't have to install an extension to use it. (If you don't see the link, then this feature is not yet enabled in your account. Adding your email address to this page might help.)


After clicking on "Report a bug", Google shows this message: "Please scroll until the issue becomes visible. Next, click anywhere in the window to take a screenshot." Click in the window and Gmail loads a new page that lets you highlight the problem, black out personal information and describe your problem. It's a really cool feature which will probably be added to other Google services in the near future.

Picasa 3.8 Released

Picasa 3.8 doesn't add too many features, but there are at least two reasons for updating to the latest version: Face Movie and batch upload to Picasa Web Albums.

Face Movie is a movie presentation centered around one person. "As the photos transition from one to another the subject's face stays aligned in one focus area, creating a unique viewing experience," explains Picasa's blog. Just select one of your contacts from Picasa's sidebar and click on the create Face Movie.


Picasa 3.8 makes it easy to upload multiple albums to Picasa Web and change the settings for the existing albums. You can delete multiple albums, change their visibility, save space by changing photo size or disable syncing. Go to the Tools menu and click on Batch Upload to access this feature.

Google's photo manager also added a surprising feature: integration with Picnik, the online photo editor acquired by Google this year. Why would you use a slow and limited online service to edit photos stored on your computer, when you can use Picasa's image editing options? Picasa's help center explains: "Use Picnik's exclusive editing features to apply effects, stickers, and frames to your photo. You can also crop, and adjust the colors of your photos right in your browser. When you click on Edit in Picnik, your photo will be transferred online. Apply the desired effects then click Save to Picasa. You'll have to option to replace your original photo or create a new copy on your computer."

In Windows, Picasa uses an Internet Explorer object to display Picnik's Flash site. I had to click on two Internet Explorer script error messages before uploading a photo to Picnik.


Unfortunately, most Picnik stickers and touch-ups require upgrading to Picnik Premium. Why would Google charge users $25 a year for this service? I remember that Google made Blogger Pro, Picasa, Keyhole's Earth Viewer (now Google Earth), Urchin, Sketchup, FeedBurner Pro/MyBrand free after acquiring the products.

Picasa Web Stats in Google Analytics

Picasa Web Albums has an option that lets you see detailed visitor stats for your photos. If you go to the Settings page, you can enable "photo tracking". The only thing you need is a Google analytics tracking code.


Picasa Web's help center explains that you need to create a new Google Analytics account (not a new Google account) to monitor Picasa Web Albums photo traffic. After creating the new account, find the account ID that looks like UA-xxxxxxx-y and enter it in the Google Analytics tracking code box from Picasa Web Albums. "Once the setup is complete, just sign in to Google Analytics and click View reports to see visitor stats for your photos. It can take up to 24 hours for Analytics to detect your tracking code."

A similar option is available for Google Docs, but only for published documents. While this feature is useful, it's not very easy to use and it's not properly integrated with Google Docs and Picasa Web. Showing simple stats, like the number of views, the top search queries and referring websites, in a special section of Google Docs and Picasa Web would be a much better idea.

Link Your Google Profile with Picasa Web Albums

Picasa Web Albums added an option to connect the service with Google Profiles. Before Google Profiles was released, each Google service used separate profiles, so you had to enter personal information multiple times.

"Picasa Web Albums are now compatible with your Google Profile! Now when you use Picasa Web Albums, you can use the same profile name and photo that you use on your Google Profile. Your Picasa Web Albums will link to your Google Profile, and your profile will link to your public albums," informs Google's photo service.


After linking your Google Profile with Picasa Web Albums, you can edit the profile and remove the link to your public albums.

If you've previously used an alias to hide your Gmail address from the URL, you can no longer use it after merging the profiles. The only option you have is to use the same ID number from Google Profiles.

It's interesting that Picasa Web's code calls this feature "merged profiles softlaunch", which suggests that users aren't required to merge profiles, but that will change in the future.

Chrome Web Store and Online Games

1up.com reports that Google Chrome Web Store will be launched in October and online games will be one of its main attractions. "Set to launch this October, the store aims to make a proper marketplace for browser games -- one that solves a lot of the issues of games on the web today, from discovery to monetization."

Google's game developer advocate, Mark DeLoura, thinks that it's difficult to find great online games, so Google Chrome Web Store tries to solve this problem by allowing users to rate games and write reviews. Chrome users will be able to install games, which adds shortcuts to the "new tab" page and grants additional permissions to the games. Not all games will be free, but Chrome users can buy games directly from the Web Store and pay using Google Checkout. Google's platform will support free trials and subscriptions, while developers will only pay a 5% processing fee for each transaction.


Will users pay for web apps in Chrome's store? More than half of the Android apps are free and paid Android apps are only available in 13 countries because of Google Checkout's limitations. Android Market doesn't make it easy to find interesting new applications and doesn't recommend other applications based on the ones you've installed. Hopefully, Chrome Web Store will do a much better job than the Android Market.

Teknologi Informasi

Apa sebenarnya yang dimaksud dengan Teknologi Informasi? Apakah teknologi informasi itu identik dengan komputer? Apakah benar telepon seluler juga merupakan bagian dari teknologi informasi? Pertanyaan-pertanyaan itu sering dilontarkan dan untuk menemukan jawabannya kita perlu memahaminya.

Teknologi Informasi biasa disebut TI, IT (Information Technology) atau Infotech. Berbagai definisi teknologi informasi telah diutarakan oleh beberapa ahli, diantaranya :

Haag den Keen (1996), Teknologi Informasi adalah seperangkat alat yang membantu Anda bekerja dengan informasi dan melakukan tugas-tugas yang berhubungan dengan pemrosesan informasi.

Martin (1999), Teknologi Informasi tidak hanya terbatas pada teknologi komputer (perangkat keras atau lunak) yang digunakan untuk memproses dan menyimpan informasi, melainkan juga mencakup teknologi komunikasi untuk mengirimkan informasi.

Williams dan Swayer (2003), Teknologi Informasi adalah teknologi yang menggabungkan komputasi (komputer) dengan jalur komunikasi berkecepatan tinggi yang membawa data, suara dan video.

Dari definisi diatas terlihat bahwa teknologi informasi baik secara implisit maupun eksplisit tidak sekedar berupa tekologi komputer, tetapi juga teknologi telekomunikasi. Dengan kata lai, yang disebut teknologi informasi adalah gabungan antara teknologi komputer dan telekomunikasi.

Penjelasan atas dua teknologi yang mendasari adalah sebagai berikut :

Teknologi Komputer
Teknologi komputer adalah teknologi yang berhubungan dengan komputer, termasuk peralatan yang berhubungan dengan komputer, seperti printer, pembaca sidik jari, danh bahkan CR-ROM. Komputer adalah mesin serba guna yang dapat dikontrol dan diprogram, digunakan untuk mengolah data menjad iinformasi. Program adalah deretan instruksi yang digunakan untuk mengendalikan komputer hingga komputer dapat melakukan tugasnya sesuai yang dikehendaki oleh pembuat program. Data adalah bahan mentah bagi komputer yang dapat berupa angka atau huruf atau simbol, sedangkan informasi adalah bentuk data yanag telah diolah sehingga dapat menjadi bahan yang berguna untuk pengambilan keputusan.

Teknologi Komunikasi

Teknologi komunikasi atau biasa juga disebut teknologi komunikasi adalah teknologi yang berhubungan dengan komunikasi jarak jauh. Termasuk dalam kategori teknologi ini adalah telepon, radio dan televisi.

PENGELOMPOKAN TEKNOLOGI INFORMASI
Telah diketahui bahwa teknologi informasi mencakup teknologi komputer dan teknologi komunikasi. Lebih rinci, teknologi infromasi dapat dikelompokan menjadi 6 teknologi, yakni teknologi komunikasi, teknologi masukan, teknologi perangkat lunak, teknologi penyimpanan, dan teknologi mesin pemroses.

Teknologi Masukan
Teknologi masukan (input technology) adalah teknologi yang berhubungan dengan peralatan untuk memasukkan data ke dalam sistem komputer. Piranti masukan yang lazim dijumpai dalam sistem komputer berupa keyboard dan mouse.

Teknologi Mesin Pemroses
Mesin Pemroses (processing machine) lebih dikenal dengan sebutan CPU (Central Processing Unit), mikroprosesor, atau prosesor. Contoh prosesor yang terkeanl saat ini, antara lain adalah Pentium dan PowerPC.

Teknologi Penyimpanan
Teknologi penyimpanan dibedakan menjadi dua kelompok, yaitu memori internal dan penyimpanan eksternal.
Memori internal (biasa juga disebut main memory atau memori utama) berfungsi sebagai pengikat sementara baik bagi data, program, maupun informasi ketika proses pengolahannya dilaksanakan oleh CPU. Dua contoh memori internal yaitu ROM dan RAM. ROM (Read Only Memory) adalah memori yang hanya bisa dibaca, sedangkan RAM (Read Access Memory) adalah memori yang isinya bisa diperbaharui.

Penyimpanan eksternal (external storage) dikenal juga dengan sebutan penyimpanan sekunder. Penyimpanan external adalah segala piranti yang berfungsi untuk menyimpan data secara permanen. Pengertian permanen disini berarti bahwa data yang terdapat pada penyimpanan akan tetap terpelihara dengan baik sekalipun komputer sudah dalam keadaan mati (tidak mendapat aliran listrik). Harddisk dan disket juga flashdisk adalah contoh penyimpanan eksternal.

Teknologi Keluaran
Teknologi keluaran (output technology) adalah teknologi yang berhubungan dengan segala piranti yang berfungsi untuk menyajikan informasi hasil pengolahan sistem. Layar dan monitor dan printer merupakan piranti yang biasa digunakan sebagai piranti keluaran.

Teknologi Perangkat Lunak

Perangkat lunak (software) atau dikenal juga dengan sebutan program. Tentu saja untuk mengerjakan tugas komputer, diperlukan perangkat lunak sendiri. Sebagai contoh Microsoft Word merupakancontoh perangkat lunak pengolah kata yang berguna untuk membuat dokumen, sedangkan Adobe Photoshop adalah perangkat lunak yang berguna untuk mengolah gambar.


KOMPONEN SISTEM TEKNOLOGI INFORMASI

Yang dimaksud dengan sistem teknologi informasi adalah sistem yang terbentuk sehubungan dengan penggunaan teknologi informasi. Suatu sistem teknologi informasi pada dasarnya tidak hanya mencakup hal-hal yang bersifat fisik, seperti komputer dan printer, tetapi juga mencakup hal-hal yang tidak terlihat secara fisik, yaitu piranti lunak dan yang lebih penting lagi adalah orang. Dengan kata lain, komponen utama sistem teknologi informasi adalah berupa :
perangkat keras (hardware)
perangkat lunak (software)
orang (brainware)

KLASIFIKASI SISTEM TEKNOLOGI INFORMASI

Sistem teknologi informasi dapat dibedakan dengan berbagai cara pengklasifikasian. Misalnya, menurut fungsi sistem (embedded IT System, dedicated IT system, dan general purpose IT system), menurut departemen atau perusahaan bisnis (sistem informasi akuntansi, sistem informasi pemasaran, sistem informasi produksi, dll), menurut dukungan terhadap level manajemen dalam perusahana (sistem pemrosesan transaksi, sistem pendukung keputusan, san sistem informasi eksekutif), menurut ukuran dan menurut cara melayani permintaan (klien-server).


MENURUT FUNGSI SISTEM

Berdasarkan fungsi yang diemban sistem, sistem teknologi informasi dapat dibedakan menjadi sistem teknologi informasi yang melekat (embedded IT system), sistem teknologi informasi yang khusus (dedicated IT system, dan sistem teknologi informasi serbaguna (purpose IT System).

Embedded IT System

Embedded IT system adalah sistem teknologi informasi yang melekat pada produk lain. Sebagai contoh, sistem VCR (Video Casette Recorder) memiliki sistem teknologi informasi yang memungkinkan pemakai dapat merekam tayangan televisi. Adapun sistem teknologi informasi pada lift dapat digunakan untuk mengendalikan gerakan lift dalam gedung pencakar langit. Misalnya, lift tertentu tidak bisa digunakan untuk lantai 2 sampai dengan 7 pada jam antara 07.00 sampai dengan jam 09.00.

Dedicated IT System

Dedicated IT system adalah sistem teknologi informasi yang dirancang untuk melakukan tugas-tugas khusus. Sebagai contoh adalah ATM (Anjungan Tunai Mandiri) dirancang secara khusus untuk melakukan transaksi keuangan bagi nasabah bank. Tentu saja sistem seperti ini tidak bisa dipakai untuk melakukan tugas-tugas seperti mengetik dokumen.

General Purpose IT System
General purpose IT system adalah sistem teknologi informasi yang dapat digunakan untuk melakukan berbagai aktifitas yang bersifat umum. Contohnya adalah Persoanal Computer (PC), yang merupakan peralatan yang dipakai di rumah atau perkantoran untuk mencatat pengeluaran, melakukan perhitungan statistik, membuat dokumen ataupun untuk belajar.

Menurut Ukuran

Ukuran dalam pengklasifikasian sistem teknologi informasi tidak harus berupa ukuran fisik, tetapi cenderung didasarkan pada ukuran informasi yang ditampung, kemampuan sistem yang ditawarkan, kecepatan pemroses, dan juga berdasarkan jumlah orang yang menggunakan sistem secara bersamaan. Berdasarkan pengklasifikasian seperti ini, terdapat berbagai istilah yang sampai saat ini tetap digunakan untuk memberikan nama untuk kelompok komputer, sekalipun parameter yang diguankan untuk mengklasifikasikannya sering kali berubah seiring dengan perkembngan teknologi yang mendukung komputer. Kelompok tersebut adalah mikrokomputer, workstation, minikomputer, mainframe dan superkomputer.

Klien – Server
Pada lingkungan yang mempunyai sejumlah komputer dan komputer-komputer tersebut saling terhubung dikenal dengan istilah klien – server (client – server). Pengertian server umumnya menyatakan sebuah komputer yang menyimpan data atau program yang dapat diambil oleh komputer-komputer lain atau menyediakan peranti seperti CD-ROM drive atau printer yang dapat digunakan oleh komputer-komputer lain. Adapaun klien (atau kadangkala dinamakan workstation) adalah komputer yang memanfaatkan layanan ayang disediakan oleh server.

Pada perkembangan lebih lanjut, istilah server tidak harus berarti komputer secara fisik, melainkan justru berupa perangkat lunak. Sebagai contoh, web server, adalah perangkat lunak yang berfungsi melayani permintaan halaman web oleh klien. Dengan demikian sebuah komputer dapat berfungsi menjadi berbagai server.

Eric Schmidt On the Future of Search

In an interesting interview for the Wall Street Journal, Google's CEO talks about the future of search. Eric Schmidt says that there are more and more implicit searches and that Google could become a virtual assistant that offers suggestions and solves problems without having to define them.

"We're still happy to be in search, believe me. But one idea is that more and more searches are done on your behalf without you needing to type. I actually think most people don't want Google to answer their questions. They want Google to tell them what they should be doing next."

As Google knows "roughly who you are, roughly what you care about, roughly who your friends are", it could suggest interesting things. For example, if you're using a smartphone, Google could inform you that there are interesting things around you (maybe a bookstore that sells a book you've added to a wishlist).

"The thing that makes newspapers so fundamentally fascinating — that serendipity — can be calculated now. We can actually produce it electronically. The power of individual targeting — the technology will be so good it will be very hard for people to watch or consume something that has not in some sense been tailored for them," says Eric Schmidt. "As you go from the search box [to the next phase of Google], you really want to go from syntax to semantics, from what you typed to what you meant. And that's basically the role of [Artificial Intelligence]. I think we will be the world leader in that for a long time."

To better understand queries and to answer questions that were never asked explicitly, Google has to learn more about users and that's one of the reasons why Google struggles to build successful social services.

Three years ago, Eric Schmidt said that "the goal [of search personalization] is to enable Google users to be able to ask the question such as 'What shall I do tomorrow?' and 'What job shall I take?' We cannot even answer the most basic questions because we don't know enough about you. That is the most important aspect of Google's expansion."

I don't think users "want Google to tell them what they should be doing next", but they probably want a tool that helps them solve problems, even when those problems can't be easily transformed into search queries. A real-word query can be a document, a spreadsheet, a list of words, an image, a sound, a short video, a location and it's really difficult to provide relevant results without targeting and personalization.

Gmail's Hidden Groups

In a previous post, I mentioned a trick that lets you create a Gmail group for the people you follow in Google Buzz. The downside was that the group doesn't update when you follow other people in Google Buzz.

It turns out that Gmail already has a built-in group for Google Buzz contacts. The group doesn't have a name and it's not displayed in Gmail's new contact manager, but you can find it in the old version of Gmail: it's the only one without a name.


Since the group doesn't have a name and it's hidden in the interface, you can't use it to send email messages or to post private Buzz messages, but you can select all the contacts and add them to another group.


There's also a hidden group for Google Latitude friends, which includes the people that can see your location in Google Latitude.

Another group lists all your Gmail Chat/Google Talk friends. Some of these people were automatically added by Google if you didn't disable "Automatically allow people I communicate with often to chat with me and see when I'm online" in the settings.

For those who miss the "all contacts" group in the new contact manager, here's the built-in group that includes both the people you've manually added ("my contacts") and the people automatically added by Google ("other contacts").

Create a Google Buzz Group

Google's contact manager doesn't include built-in groups for Google Chat friends or for the people you follow in Google Buzz. Fortunately, you can easily create a group for the people you follow in Google Buzz using a clever trick found by Siegfried Hirsch:

1. Go to Gmail's contact manager and search for http://www.google.com/profiles. Here's the URL for the search results.

2. Select all the results, click on the "Groups" drop-down and then on the "Create new" option.

3. Create a new group called "Buzz".

This works because Google automatically adds each Google Buzz user you follow to your contacts list and also includes the address of the Google Profile. If you've manually removed Google Profile address or added Google Profile addresses to other contacts, the results won't accurately reflect your Google Buzz group. Obviously, the group won't update automatically when you follow/unfollow Google Buzz users.


Google could use a lot of information from other services to enrich Google Contacts: the photos you tag in Picasa Web Albums, information and links from Google Profiles, Google Latitude location, the most recent Google Buzz message, but that will probably happen when Google Me is released.
