Samsung is getting really serious about their Galaxy S line, with the international Galaxy S version already doing great, the four US variants, and a confirmed Android tablet called the Galaxy Tab coming soon.

Apparently Samsung recent went to developers and asked them to prepare their apps to run perfectly on their new Android tablet. Samsung contacted the Plex6 team about their Magic 8 Ball app, since it wasn't rendering properly on the 7 inch display of the Samsung Galaxy Tab:

Dear Plex6 Team,
We would like to preface this email with Samsung's enthusiasm to give Mobile
device users enhanced Application experiences. Samsung Electronics is
committed to making Mobile and Tablet PC spaces comfortable and enjoyable
ones and your support for this would be highly appreciated by Samsung
Electronics.
It has come to our attention that your application [Magic 8-Ball] submitted
in the Android Market returns following error(s) when operated on our soon
to be released Samsung Android Tablet PC.
Please find the error(s) occurred on Samsung Android Tablet PC below.
Application does not properly display on Samsung Android Tablet 7inch
screen (600X1024/WSVGA) and draws a black background around the application
due to Compatibility-Mode display.

Please modify and adjust your application so that it would support the best
possible display on the Samsung Android Tablet device screen
(600X1024/WSVGA).
This will ensure your application to provide a consistent environment across
all devices and that you can deploy to any new devices that offer different
screens in the future.
**
Samsung Electronics is focused on strengthening its Android device line-up,
therefore, our mutual efforts on each application will be beneficial for
both parties.

W00t! Seems like Samsung is trying to make sure that their Galaxy Tab is just as awesome as their Galaxy S lineup. Now if we could only get some confirmed specs on this thing.

Who isn't getting Froyo? Well, it looks like unlocked HTC Desire's in Europe are no longer in the ignore list, as there is now an official press release that states that they will be getting the long awaited 2.2 update.

The upgrade is set to include:

• 720P Video Recording
• HTC Sense Updates
• App Share
• Improved Keyboard
• HTC's new phone features
• Sync features to allow iTunes syncing
• More

Apparently, Mark Moons was mistaken in his time period for the Froyo release. Full press release below.

The Android 2.2 (FroYo) update for HTC Desire will start rolling out across Europe this weekend. As well as including the complete set of Android 2.2 features, the update will contain a few special additions of our own through the latest iteration of HTC Sense. The update will provide 720p video capture, HTC's App Share widget, as well as our enhanced HTC Caller ID, and improved multi-language keyboard. Also, though the update, HTC Sync will allow HTC Desire users to sync their music with iTunes.
HTC Desire users will be notified that the over-the-air update is available to download when their phone automatically checks for software updates. The update won't delete any of the phone's content. However, due to the size of the update, we would advise using a WiFi connection to download it wherever possible to avoid additional data charges.
This update will initially roll-out to unlocked HTC Desire handsets. Operator specific versions of the update are undergoing testing and we expect to make them available in several weeks' time.

WordPress is a powerful content management system, and its popularity as a portfolio solution is enticing to many. There are a lot of themes out there that claim to do the job, but if you're as picky as me you'll find some pretty annoying flaws in many of them.

In my search for the best of the bunch, I installed about 30 offerings (out of the hundreds I looked at) and after trying them out and changing my mind a couple of times I finally settled down with a theme. This took me months, so I'm going to save you the bother and present the five free Wordpress portfolio themes that made my own particular shortlist.

SimpleFolio The Best All-Rounder

Despite being a tricky free WordPress theme to set-up, SimpleFolio by Omar Corrales is worth the hassle. For your troubles you'll get a clean and easy-to-navigate theme with a separate portfolio section (with the option to exclude portfolio posts from your blog) and a home screen to die for.

The home screen includes a JavaScript front-page slider to exhibit portfolio entries, which does a great job of making your work look awesome with its smooth transitions. There are a further three widgetized areas on the home page, so adding a contact form or Twitter plug-in is as easy as pie.

If you like the look of this theme and fancy giving it a go, then you're going to need a little help. There's a fantastic little guide over at WordPress Handyman which guides you through the ins and outs of setting up and maintaining your new portfolio. As always with WordPress, you can edit the style.css file to suit your personal tastes.

Vikiworks Infinity For Social Media Types

For an aesthetically pleasing, majorly customizable portfolio that's plugged in to Flickr, Twitter and Delicious, look no further than Infinity by Vikiworks. The free WordPress theme follows a three-fixed column style, and whilst not being widget ready could probably be modified with some serious Notepad'ing.

There are two PSD files to download as well as the theme, which makes customization in Photoshop that little bit easier. Blog posts themselves are presented in two thumbnail cover-style columns to the left of the page, so if you're not bothered about separating your work and your blog then this one's for you.

For the more courageous there's a sister theme called Mashup based on Infinity, only with widgets and a style switcher. The developer has appealed for help in completing it, and needs guinea pigs willing to give it a go. If you're not averse to beta testing, you can download Mashup here.

FolioGrid For Speed-Freaks, Designers, Photographers & Artists

This sharp looking offering from FrogsThemes has a little something for everyone. Utilising the tried-and-tested grid layout, the theme comes in a variety of colours and is easily altered with some handy CSS. All the styling is done through the theme's stylesheet, meaning you really can open up and customize this one.

The menu lives at the top of the page, and is always accessible from anywhere on the site, making it a cinch to navigate. There's some lovely use of jQuery for slick transitions, and the theme is widget-ready. For a fast and lightweight WordPress portfolio, FolioGrid does the job.

Fullscreen For Style-Conscious Photographers & Videographers

If photos are the order of the day then you may want to pay close attention. Fullscreen is a portfolio package developed by Graph Paper Press that delivers nothing but a menu and blog posts (represented by just images). It all makes for a very sexy looking clean interface, with some fancy JavaScript image rollover effects for added garnish.

One thing to look out for is some issues with the menu not displaying correctly in older versions of Internet Explorer, though some of you won't really care (and those that do can customize, of course).

Images can be implemented into posts using the WordPress media gallery, which makes for easy posting. If you want your photo or video work to be the main focus of your site, then this theme will honour your wishes.

Contrast The Black Sheep

SmashingMagazine once hosted a typographic layout competition for WordPress and Tumblr themes, and Paul Linder's Contrast didn't win. But that doesn't matter, because it's awesome all the same.

Using nothing but XHTML and CSS, it's lightning quick and beautiful to look at. Presenting you with a straight-up black and white home screen, Contrast is designed to be left as a portfolio rather than a blog as well.

As the focus is on text, many writers, copy-editors or web designers may find this appealing, though the minimalist design could suit anyone. It's bold, unique and quick.

Many artists have used pencils to create beautiful pieces of work but only one creates stunning masterpieces on the tip of one. Microscopic artist Dalton Ghetti spends up to two-and-a half years painstakingly crafting each handmade piece on the graphite of a pencil.

The New York Times reports

Mr. Ghetti, who owns about as many possessions as a monk, is aware how unusual his craft is. He started carving tree bark when he was a child and experimented with everything from soap to chalk before settling on graphite. It's second nature now, and for 90 percent of his work, all he needs is a sewing needle, a razor blade and a carpenter's or No. 2 pencil.

The pencil tip is great; it's like a pure, very homogenous material,' he said. It cuts in the same direction, not like wood, which has a grain. But when I tell people how long it takes, that's when they don't believe it. That's what amazes people more, the patience. Because everything nowadays has to be fast, fast, fast.'

It is really remarkable niche in the art world. There have been artists who use pencils as part of their craft, but none use the smallest and most fragile part: the pencil lead.

I was looking through the book of Android phone apps yesterday

and came across an app called Useless Facts, a free app with over 9,000 fun facts supposedly designed for frivolous entertainment, which offers this as their one example fact:

Oh. That's not very fun. It's actually the opposite of fun.

That's their example to make me want to download the app? Is the app actually full of amusing facts, and they just chose a poor representative example, or even worse, is this example actually the least depressing fact from the app? Are the other 8,999 all various calculations of the 9/11 death toll? USELESS N' FUN!!!!

I guess my real question is, is there a way I can download this app but have it count as just downloading it to objectively see how perverse it is, without actually counting it as me downloading the app? Crap. Guess the example worked.

Slacker Radio has gained its share of popularity among music fans for offering a nifty cache feature that other mobile music apps lack; after creating a station, you can save it for offline use (perfect for underground subway rides or long plane trips). Now it's distinguishing itself from other services even more by incorporating still more diverse content.

Slacker isn't the first service of its kind to incorporate news content Sirius | XM does something similar but this move does serve to give Slacker what could be seen as an edge over Pandora, which only serves up music and doesn't allow caching.

For 14 days, basic Slacker users will be able to access ABC News content; Slacker Plus users can keep on tuning in after the two-week period ends (the Plus subscription is $3.99 per month). The content which includes segments from Good Morning America, anchored by Robin Roberts, George Stephanopoulos, Juju Chang and Sam Champion; and Nightline anchored by Terry Moran, Cynthia McFadden and Martin Bashir is located within the mobile app in a folder marked News, and works in much the same way music stations do (i.e. you can skip stories).

You can also choose to add hourly news updates to any of your stations, but the process to do so is laborious, to say the least. First, you have to futz around on the website, create a station, go to the Fine Tune tab to select that option, save the station, make it a Favorite, and, if you're already logged into Slacker on your mobile device, sign in and out to make the Favorited station appear. Sure, you can choose to Fine Tune any pre-existing station which is easier than creating your own playlist or choose to have ABC News turned on for all your stations by surfing over to Account Settings, but all this still requires signing online. We wish it were possible to do all that within the app, as going through all that song-and-dance degrades the whole easy and accessible aspect of it.

The site has grown at an incredible rate since its inception, and it's always struggled to keep up (technically speaking) with user adoption. Ever since its userbase spread beyond the tech elite to more mainstream social media users, the site has been subject to a seemingly unending string of growing pains.

In response to a wave of failures last month during the World Cup, Twitter engineer Jean-Paul Cozzatti posted that the company's network was improperly configured, leading to downtime and trouble with features.

Cozzatti claimed that the company had doubled the capacity of its internal network, improved its monitoring and rebalanced its traffic to prevent future downtime.

For much of 2009, Twitter's biggest challenge was coping with our unprecedented growth (a challenge we happily still face), he wrote. But as this week's issues show, there is always room for improvement.

Apparently, the improvements made last month were not enough to keep up with user growth and their demands on the service.

Cozzatti posted again today to address Twitter's issues Monday, comparing the engineering team's work on scaling the app to riding a rocket. To give you an idea of how fast that rocket is soaring through the social media universe, we reported in April that the service had 105 million users. In his post today, Cozzatti said Twitter now has 124 million registered users.

Scalability and uptime are the team's top priority; in fact, Cozzatti noted, other projects are being put to the side until these problems can be thoroughly solved. He stated that Twitter's engineers have made more than 50 performance and optimization tweaks since the site's World Cup woes, including doubling throughput to the database that stores tweets, improving how the app uses memcache and improving page caching of the front and profile pages, which helps to reduce page load time.

Nevertheless, There are still times when we run into problems unrelated to Twitter's capacity, Cozzatti admitted.

Monday's issues serve as a perfect example. During the database malfunction and restart which covered a 12-hour period users were unable to login, sign upor update their profile information and design. In the end, wrote Cozzatti, this affected most of the Twitter ecosystem: our mobile, desktop, and web-based clients, the Twitter support and help system, and Twitter.com.

While Twitter is getting its own data center this fall and is actively recruiting more engineering talent, the company clearly needs to implement the long-term solutions we're reading about. To have the cultural cachet of a web service such as Google search, Gmail, Facebook or any of the apps we rely on for day-to-day work and life and we have the distinct impression that Twitter does, indeed, hope to be part of that cadre it must first and most importantly achieve an acceptable uptime ratio. All the partnerships, revenue and media buzz in the world can fall a bit flat when the app itself doesn't work.

That being said, we're certain Twitter can and will make the needed improvements for scalability, and growing pains are good pains to have.

Are you confident that Twitter can become reliable and stable in the near future? Or do you foresee more significant downtime from this service? What will it take for Twitter to grow as quickly as its users require?

It's a beautiful thing to watch people tweet. Especially when you try to figure out what they're tweeting about, how they feel, and where they're tweeting from then put that all on a map and animate the changes over time.

Researchers from Northeastern University and Harvard College recently built a pretty and captivating visualization of U.S. Twitter users' moods, as determined by sentiment analysis. You can watch two days worth of tweeted moods in this video:

Watching the cartogram pulse as it indicates the proportional volume and sentiment of tweets is probably more interesting than the researchers' conclusions about their data: people are happier on weekends than weekdays; West Coast happiness trends are usually about three hours after East Coast happiness trends. Still, it's neat to learn that Thursday evening aka just about the time I'm posting this is the time of the week Twitter users tend to express the most negative sentiment.

Meanwhile, over at Betaworks, they've just posted a visualization of the record-setting sustained volume of tweets from around the world during the World Cup. There's no sentiment analysis here just counting of relevant hashtags but you can see the volume of tweets corresponding with the occurrence of games that people in a country are interested in.

People seem to tweet less about being frustrated than being triumphant; for the championship game, Betaworks noted an immediate lack of traffic in the Netherlands after losing while the attention in Spain persisted through the next morning. Or it could be that disappointed tweeters just left off the proper hashtag formulation when lamenting their team's loss.

These aren't the first Twitter geography-plus-time visualizations videos, of course. Here's one from last year that maps tweets with the words just landed and just arrived in:

Just Landed 36 Hours from blprnt on Vimeo.

Here's another of tweets from people who were pleased about Barack Obama's inauguration. And here's one from the New York Times depicting tweets during the Super Bowl. (Those two aren't embeddable, so you'll have to click through.)

Perhaps the data geeks who made these were too busy thinking about the visuals, but for some reason or another none of them include a soundtrack. So it's up to you to put some trippy music on, chill out, and watch the Twitter visualizations.

An interesting discussion of the role of "traditional media" in the wikileaks Afghanistan journal

That WikiLeaks went to the press with the Afghanistan war logs shows old-fashioned news organisations still have a role to play

Of all the questions raised by the Afghanistan war logs, perhaps the most intriguing is this: why would an organisation as independent-minded and disdainful of the traditional media as WikiLeaks seek out those very media as partners rather than going it alone?

My necessarily speculative answer is that WikiLeaks founder Julian Assange, who's made a speciality of revealing embarrassing governmental secrets, learned something important earlier this year. That's when he briefly caused a sensation by releasing video of a US Apache helicopter firing on Iraqi civilians, killing (among others) a Reuters photographer and his driver.

The lesson: shocking material and a flair for public relations may be enough to get you noticed. But if it's credibility you want, then old-fashioned news organisations still have something to offer.

WikiLeaks made some 92,000 documents about the war in Afghanistan available to the Guardian, the New York Times and Der Spiegel a month ago, giving professional journalists time to sort, vet and craft narratives from jargon-laden field reports compiled by US officials.

The documents add sickening details to the broad outlines of what we already knew: that major elements of Pakistan's intelligence forces are in bed with the Taliban; that chaos and confusion in Afghanistan has led to civilian casualties; and that among the burdens the Afghan people must bear is a corrupt and ineffective government.

The Obama administration has lambasted WikiLeaks for releasing the documents, arguing that the situation has improved since 2009, when the most recent of the official reports were compiled. But no one has questioned the authenticity of the documents themselves, even if the reliability of the information contained therein appears to be of variable quality.

In effect, Assange chose to act as Daniel Ellsberg, the insider who leaked the Pentagon Papers the US government's own secret history of the Vietnam war to the Washington Post and the New York Times. But it was just a few months ago that Assange tried out the role of Ben Bradlee, the Washington Post executive editor who published those papers.

In April, you may recall, WikiLeaks uploaded two versions of the Apache helicopter video. One was an edited, 18-minute version that it titled Collateral Murder, which begins with a quote from George Orwell: "Political language is designed to make lies sound truthful and murder respectable, and to give the appearance of solidity to pure wind." The other, 39 minutes long, was raw footage with no commentary.

The American secretary of defence, Robert Gates, denounced the video as having been taken out of context. No surprise there. But as Raffi Khatchadourian notes in a profile of Assange published in the New Yorker, the media turned Gates's way within days of the release. And in fact, when you watch the video and listen to the Americans on board the helicopter, you can see that the crew members believed, rightly or wrongly, that they were firing on a legitimate target.

Even the comedian Stephen Colbert, in an interview with Assange, dropped his rightwing-blowhard persona momentarily to make a serious point, calling the edited version "emotional manipulation" and telling his guest: "There are armed men in the group. They did find a rocket-propelled grenade among the group. The Reuters photographers who were regrettably killed were not identified as photographers. And you have edited this tape, and you have given it a title called Collateral Murder. That's not leaking. That's a pure editorial."

(An aside for British readers not familiar with Colbert and thus puzzled at my quoting a comedian: it is a sad but undeniable reality that the two most incisive American media critics today may well be Colbert and his fellow fake anchorman Jon Stewart.)

Around the time that the video was released, hubris among the WikiLeakers was thick. In the New Yorker piece, we hear from a friend and supporter of Assange's, a Dutch hacker named Rop Gonggrijp, who smugly says that "we are not the press" and "the source is no longer dependent on finding a journalist who may or may not do something good with his document".

Yet here we are, several months later, and Assange is acting very much like an old-fashioned source, seeking out journalists even as he uploads the raw source documents to the web.

In the felicitous phrase of New York University journalism professor Jay Rosen, WikiLeaks is "a stateless news organisation". But as the New Yorker piece makes clear, Assange and his fellow activists are less interested in news than in making a political impact. And it is an organisation only in the loosest sense of the term. Given those realities, it makes sense for them to work with journalists rather than to posit themselves in opposition to the media.

"WikiLeaks was soaking, drowning in data," Rosen's NYU colleague Clay Shirky tells David Carr of the New York Times. "What they needed was someone who could tell a story. They needed someone who could bring accuracy and political context to what was being revealed."

What I am suggesting is not that old media have triumphed over the new. Rather, I'm simply pointing out that each has its place in the media ecosystem.

WikiLeaks, with its singleminded focus on casting about for whistleblowers and protecting their identity through encryption and secrecy, can obtain material that eludes established news organisations. And professional journalists can vet, make sense of and impart credibility to that material in ways that not all new-media ventures (at least not WikiLeaks) can.

The result is a powerful indictment of the war in Afghanistan and a major challenge to Barack Obama.

Back in character, Colbert asked Assange: "What is the purpose of letting the public know? It's like you're saying it's better to know than not to know. Have you not heard ignorance is bliss?"

It's way too late for that now.

I agree with this, I loved my Kindle. I sold it when I got my iPad because it didn't make sense to have two devices, but it was great for reading. If you're a reader, at this price now it doesn't make sense for you not to own a Kindle. (if you don't have the need / want for an iPad)

Yesterday, Amazon announced a new Kindle, similar in design to the new DX and just $140/$190 for WiFi-only and 3G models, respectively.

Naturally, the tech press is already declaring it dead, because the tech press loves product killers and other perceptions to completely rule out entire classes of products because they lack the empathy or worldview to recognize these products' markets.

Dave Winer says:

When I read on tech blogs that Kindle is a goner, I think these people must not read very much.

I love the Kindle. The iPad didn't kill it. Amazon is going to sell a ton of these, especially at this new price point.

Reading on the iPad is a bit of a kludge. You can read on it, and it's a lot better than reading on a computer, but it's still too reflective, heavy, bright, and power-hungry compared to the Kindle.

People often assume that the iPad's backlit LCD screen is an advantage over the Kindle because it doesn't need a separate light to be read at night. But the Kindle's e-ink screen is actually more versatile for different lighting: not only does it work in bright sunlight just as well as paper, but I find it easier to read a Kindle at night with a small lamp on than with an iPad in the dark, even using dark mode and low brightness. And I often can't use those same nightstand or headboard-clip lamps with the iPad to light the area less harshly because the iPad's screen is too reflective. The iPad is also too heavy to comfortably hold in most ways for long periods, and its wide range of software capabilities can be distracting. When you're holding a Kindle, all you can do is read. When I read on an iPad, I always want to go check my email. And my feeds. And Tumblr. And Twitter. Just for a minute.

The iPad is a great casual computer, but the Kindle is the superior reading device.¹ And there doesn't need to be any killing. If you really like an iPad for its other uses, now that a Kindle's entry price is $140, it's perfectly reasonable to have both.

Tiff and I are taking our first backpacking trip in a few weeks. We'll presumably have no access to AC power for 6 days, and we'll likely regret carrying anything heavy or unnecessary. But we'll have times at camp in which it will be nice to be able to entertain ourselves.

I'm not bringing the iPad. I'm certainly not bringing a laptop. I'll have my iPhone for emergencies, but powered off to conserve its battery. I'm bringing the S90, not the 5D Mark II.

And I'm bringing a Kindle, loaded up with books and Instapaper compilations, in a Ziplock bag for waterproofing. No case, no charger, no extra batteries. Total weight: 10 ounces. (I'll be carrying more coffee than that.) If it breaks, it's a lot cheaper to replace than an iPad. Its battery will outlast the trip, even with heavy use. It holds so much text that I'll always have a great selection and more than enough supply. And I'm simply bringing a few extra sets of AAA batteries (2 oz.) for my headlamp to light it at night if needed.

Gizmodo and the like probably don't care that the Kindle is the perfect device for so many uses like this that people encounter on a regular basis in Real Life. But Kindle owners, and Amazon, don't need them to.

Hey, they're just doing their part to help prevent prostate cancer. Ms. Fix-It

What seemed pretty far-fetched at one point in time actually doesn't seem so out of bounds now that we know what it is, right? If you haven't been keeping up on all things Apple, you can think of the Magic Trackpad as a much larger MacBook Pro trackpad with the same rough design identity as Apple's Bluetooth keyboard. It has 4.5 inches of multi-touch and gesture-capable glass, and even will click thanks to the fact that the feet underneath click. Using something like this on a desktop is a little disconcerting at first, as most everyone is used to having the trackpad right under the keyboard, not next to one. After a day of work usage, we're pretty comfortable with the peripheral. Though, we're just not sure yet if we'll be moving the AA batteries in our Magic Mouse elsewhere just yet.

Remember the CrunchGear Geek Weekend series, where we attempted to show some fun stuff to do in various cities across the U.S.? Yeah, we kind of let that peter out, didn't we? Also, there are lots of great non-geek things to do in and around cities. This is especially important for families: the kids might be more interested in Tecumseh! than the early television museum. With the A Day's Outing website, and now its new iPhone app, you can quickly find all sorts of interesting things to do.

This is a super simple app, and provides a nice front end to the website. You plug in what kind of activities you want to see, a date range (today, this weekend, next 7 days), and define a range (5 miles, 30 miles, 60 miles, etc). The app will query the A Day's Outing site and return a list of things going on. You can toggle between list view and map view, and you can get driving directions to any destination you select.

If you don't have an iPhone, you can simply use your smartphone's browser to access the website to get the same functionality: it'll just involve a bit more scrolling around on the page.

I like the presentation of this app. I find it calming. It's simple and uncluttered. My only gripe is that the back button is a little too small for my meaty fingers.

If you're making a cross-country road trip with your family, or just visiting in-laws for the weekend, A Day's Outing ought to let you find something interesting to do. It's only $3.

I swear! I didn't even touch him!

Many news outlets, including ReadWriteWeb reported yesterday that the first piece of Android malware may have been discovered in the wild. It now appears that we were mistaken. In an interview with Android Tapp Jackeey Wu, the developer of the wallpaper app in question, denied malicious intent. He said he was gathering device information to take advantage of favoriting features in Android.

Sponsor

In my applications I collected some device data, not user data. I collected the screen size to return more suitable wallpaper for the phone. More and More users emailed me telling that they love my wallpaper apps so much, because that even "Background" can't well suited the phone's screen.

I also collected device id,phone number and subscriber id, it has no relationship with user data. There are few apps in Android market has the favorites feature. Many users suggest that I should provide the feature so I use the these to identify the device, so they can favorite the wallpapers more conveniently, and resume his favorites after system resetting or changing the phone.

In a follow-up on its blog, Lookout, the security company that originally reported that the wallpaper apps were transmitting data, notes that the app did disclose that it was accessing phone data. However, not every app that accesses data actually transmits it off the device, and Wu's apps did not disclose that phone information would be collected (enterprises most certainly are not going to want employees voice mail passwords transmitted to third parties, regardless of that third party's intentions). Whether Wu himself knew he'd be collecting passwords along with users' phone numbers, we do not know. We have not been able to find a way to contact Wu.

We will update with additional information as it becomes available.

When you read a plan tree you should start from the bottom up. In the above example begin by looking at the access operators (or the leaves of the tree). In this case the access operators are implemented using full table scans. The rows produced by these tables scans will be consumed by the join operator. Here the join operator is a hash-join (other alternatives include nested-loop or sort-merge join). Finally the group-by operator implemented here using hash (alternative would be sort) consumes rows produced by the join-opertor.

The execution plan generated for a SQL statement is just one of the many alternative execution plans considered by the query optimizer. The query optimizer selects the execution plan with the lowest cost. Cost is a proxy for performance, the lower is the cost the better is the performance. The cost model used by the query optimizer accounts for the IO, CPU, and network usage in the query.

There are two different methods you can use to look at the execution plan of a SQL statement:

1. EXPLAIN PLAN command - This displays an execution plan for a SQL statement without actually executing the statement.


2. V$SQL_PLAN - A dictionary view introduced in Oracle 9i that shows the execution plan for a SQL statement that has been compiled into a cursor in the cursor cache.

1. EXPLAIN PLAN command


2. V$SQL_PLAN


3. Automatic Workload Repository (AWR)


4. SQL Tuning Set (STS)


5. SQL Plan Baseline (SPM)

SQL> EXPLAIN PLAN FOR

 4   where p.prod_id = s.prod_id

1. Basic
   The plan includes the operation, options, and the object name (table, index, MV, etc)
   
2. Typical
   It includes the information shown in BASIC plus additional optimizer-related internal information such as cost, size, cardinality, etc. These information are shown for every operation in the plan and represents what the optimizer thinks is the operation cost, the number of rows produced, etc. It also shows the predicates evaluation by the operation. There are two types of predicates: ACCESS and FILTER. The ACCESS predicates for an index are used to fetch the relevant blocks because they apply to the search columns. The FILTER predicates are evaluated after the blocks have been fetched.
   
3. All
   It includes the information shown in TYPICAL plus the lists of expressions (columns) produced by every operation, the hint alias and query block names where the operation belongs. The last two pieces of information can be used as arguments to add hints to the statement.
