A few WordPress superstars have teamed up to create WPEngine, a new and very exciting platform that promises to do all of the above and more.

WordPress has become the killer platform for many bloggers, small businesses and developers/consultants with multiple clients.

However, there's a middle ground between a WordPress.com blog and a hosted WordPress site that a few apps are attempting to cover. This middle ground includes people who don't have the technical skills of a WordPress developer or even a website administrator but who still want to take advantage of a greater part of the WordPress ecosystem of plugins and other benefits.

About the Product

WPEngine offers a WordPress VIP-type experience for smaller-scale websites, and it includes top-notch support, one-click backups, optimization for speed and scalability, and security features that include automatic software upgrades. Also, you'll be able to use any WordPress plugins, themes, custom CSS or JavaScript you like.

The platform gives users a set of specially curated plugins that have been vetted for security and have the WP Engine team's absolute recommendation. If there is a plugin that isn't in our list, reads the site, you should feel empowered to use it anyway.

Most of all, WPEngine promises its users simplicity and a seamless transition and integration experience.

The platform seems like it will work for bloggers, for businesses, and also for small dev shops that need to keep an eye on several WordPress-based sites.

About the Team

While the product sounds fabulous and, indeed, just what the WordPress ecosystem needs, product is only part of what makes a good startup; the company also needs to have a great team. WPEngine was developed by Aaron Brazell, a well-known figure in the WordPress universe who authored The WordPress Bible; blogger and developer Jason Cohen; and Cullen Wilson, an Austin-based developer. The startup is also under the wing of Ben Metcalfe, who has made a habit of picking good bets in the startup world. His last pick, NutShell Mail, experienced the Silicon Valley version of a Cinderella story and was acquired recently by Constant Contact. Altogether, it's a bit of a dream team for a WordPress product.

Finally, the platform got the following 140-character thumbs-up from WordPress founder Matt Mullenweg this afternoon: I think it's a nice complement to first-party solutions, especially for businesses that use [WordPress] as a CMS.

About Signup and Migration

We talked a bit with some of the WP Engine team today about migrating blogs including themes, customized TypeKit fonts, comments and more over to the WP Engine platform, and it's a process we're eager to test. We'll be trying it out soon, and we will report back on the results.

In the meantime, if you're interested in learning more, sign up for WPEngine's beta program. The platform will be open to the public very soon. You can test the platform for 15 days free of charge, and it costs $50 per month thereafter. There are no contracts, and you're free to move your blog elsewhere at any time.

What do you think so far? Is this something you'd be interested in trying? Do you think it will be useful for businesses and WordPress developers? Let us know in the comments.

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)

Formatting

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.

Twitter is rolling out a new feature to help you discover new people to follow:

The algorithms in this feature, built by our user relevance team, suggest people you don't currently follow that you may find interesting. The suggestions are based on several factors, including people you follow and the people they follow.

This is a very welcome move by Twitter. TechCrunch says they're building a Social Graph, while VentureBeat suggests a PeopleRank algorithm powering these suggestions.

The problem? Twitter badly needs a Matt Cutts.

Active Users

Here are stats on number of tweets by Twitter Users by RJMetrics from Jan 2010:

• 80% of all Twitter users have tweeted fewer than 10 times.

That means only 20% are active users.

The 2009 Annual Report from Barracuda Labs independently confirms these findings.

• 34% of Twitter users have no tweets
• 73% of users have less than 10 tweets

Spam Accounts

Now, from the remaining 20% of active Twitter users, how many users are spam?

According to TwitSweeper in March 2010: 5%.

These are accounts who tweet "make money fast online!", "multiple sources of passive income", "view my naked pics!", etc.

That leaves 15% of Twitter users who are real and may be considered worth following.

Why This Is A Problem

If Twitter is trying to build a meaningful, relevant social graph, they have to clean up first.

Twitter's PeopleRank faces the same challenge as Google's PageRank: Blackhat SEO. These spam accounts are followed by each other and by other fake accounts all to provide a semblance of a active social user graph and avoid algorithmic detection. These are virtually indistinguishable from real users and will become part of the suggested users ecosystem.

How many times do we encounter spam accounts on Facebook? How many times do we see spam results in the first page of Google search results? In contrast, how many times do we get @replies from spammers on Twitter?

A contaminated social graph or PeopleRank system is harmful to Twitter from an investor, user, and advertiser point of view. It will be great if Twitter is able to suggest whom to unfollow and get rid of all these inactive, fake, and spam accounts.

Name: KnowPro

Quick Pitch: KnowPro apps helps people learn new topics, test for competence, or compete against friends or colleagues through social platforms.

Genius Idea: It's no secret that the iPhone can be used as an educational resource, and KnowPro's extensive lineup of tutorial-style iPhone apps demonstrates just how pocket-friendly and fun learning can be.

KnowPro has developed dozens of apps for practically any educational purpose. App categories cover subject matter such as animals, science, history, music, politics, business and pop culture.

In the science category, for instance, Board Review: Pharmacology is designed to help pharmacologists prepare for their board exam, Periodic Table of the Elements includes quiz questions on all 112 elements, and there's even an app to help with preparation for the biology portion of the MCAT.

Each app tutors users by testing them with quiz questions. At the beginning of each randomized quiz, you can set how many questions you want to answer. Then, for each question, you'll be presented with four possible answers. Get a question right and you'll advance to the next question. Get a question wrong, and you'll need to continue guessing until you get it right.

At the end of each quiz you can then publish your score to the service-wide leaderboard or publicly share it on Facebook or Twitter.

KnowPro's selection of apps is impressive, so if there's a particular subject matter you'd like to master, chances are a KnowPro app can help. The only downside is that each app comes at a price, with the more sophisticated tutorials costing as much as $6.99 apiece. Still, being able to use your iPhone in lieu of flashcards could make the expense worthwhile.

Sponsored by Microsoft BizSpark

BizSpark is a startup program that gives you three-year access to the latest Microsoft development tools, as well as connecting you to a nationwide network of investors and incubators. There are no upfront costs, so if your business is privately owned, less than three years old, and generates less than U.S.$1 million in annual revenue, you can sign up today.

Acer Aspire 1410-74G25n - 299

Acer's Aspire laptops represent the company's consumer range, and the Aspire 1410-74G25n is a CULV (Consumer Ultra Low Voltage) laptop that offers fantastic value for money.

Performance isn't this laptop's strong point, but it isn't meant to be the laptop offers superb portability instead. At only 1.4kg, it's a pleasure to carry around. The small form factor makes it very easy to fit into almost any bag, but if you're after th slimmest machine possible, go for the Elonex Sliver instead.

The Aspire 1410-74G25n is put together well, and will provide good durability on the road. The shiny screen lid does quickly attract fingerprints and grime, but the mock brushed-aluminium palmrest inside doesn't, and looks and feels great.

The keyboard is very firm, but is also flat and therefore easy to get lost on when typing at speed. Unfortunately, the proximity of the touchpad to the keyboard makes it all too easy to brush against it while typing, causing irritating and erratic cursor behaviour.

The Aspire 1410-74G25n has the latest 802.11n high-speed wireless networking technology making it well suited to connecting to a router or hotspot at home or in a cafe and it's also the only laptop here to boast both VGA and HDMI out ports, offering good flexibility when connecting to external analogue and digital monitors.

The Acer Aspire 1410-74G25n sets a very high bar for the other laptops on test, and the excellent battery life will be a clincher for many buyers.

Advent Modena - 339

Advent is PC World's in-house brand and comprises a range of affordable entry-level machines and the Advent Modena is a usable option for the first-time buyer and includes a bright and vibrant screen, but performance is poor.

The slim chassis carries the same basic design scheme we've come to expect from the Advent range, but its patterned glossy lid and matt-plastic interior create a nice contrast.

The plain black design is a little uninspiring, but doesn't detract too much from the sleek consumer styling.

At 2.5kg, the Advent Modena is easy to use around the home or on shorter journeys. With a depth of just 33mm, it slips easily into a carry case, so it's disappointing that the battery runs for just over two hours .

Surprisingly at such a low-price, high-speed wireless connectivity is provided by 802.11n Wi-Fi. An integrated camera is also in place, fitted above the screen, and lets you capture snapshots and even record video for easy online video messaging use.

Offering good usability, a great screen and ample storage at such a low price, the Advent Modena is sure to please first time buyers looking for an affordable and portable bargain.

Lenovo ThinkPad X100e - 355

Lenovo's ThinkPad range is known for offering arguably the best business laptops you can buy, but prices have traditionally been quite high. The ThinkPad X100e remedies this and brings effortlessly high-class corporate usability to the entry-level market.

The first thing you notice is how small the Lenovo ThinkPad X100e is. Weighing just 1.5kg, it easily fits into even the smallest luggage for regular travel use. The 226-minute battery life is bettered by the eMachines G525-902G16Mi but provides basic mobility.

Despite the low price, none of Lenovo's famed build quality has been lost. The matt plastics and rigid chassis provide ample resilience and will easily withstand the knocks of life on the move, while the plain black design is sleek and stylish.

ThinkPad keyboards are rarely bettered and the Lenovo ThinkPad X100e is no exception. Unusually for Lenovo it uses the isolated-key style with each key cut through a hole in the chassis. The board is also spill-resistant and is both spacious and responsive, making it by far one of the best at this price point.

While its mixed levels of power and small size make it more akin to a netbook than a laptop, there's no denying the sheer quality of the ThinkPad X100e. By offering the key strengths of more expensive machines at a cheaper price, this is a truly great ultraportable for the price.

eMachines G525-902G16Mi - 397

While eMachines is not the best-known brand, it provides a good range of entry-level laptops ideal for those on a budget.The eMachines G525-902G16Miis a highly likeable big screen laptop, but is unfortunately flawed by limited power and features.

With its striking 17.3-inch screen, this is a great choice for viewing movies and photos. As well as its size, the screen on the eMachines G525-902G16Mi is far brighter and more vibrant than its rivals, making it comfortable to view in all conditions. We found the Super-TFT coating inevitably reflective, however.

Disappointingly, graphics performance is very low, with only the most basic multimedia use possible. The integrated Intel graphics card quickly struggles with demanding video editing tasks, but basic photo editing is possible.

Where the eMachines G525-902G16Mi truly stands out is its solid build quality and great usability. While the matt-black chassis and textured lid provide a conservative appearance, they also make the laptop very resilient, ensuring you can let the family loose on it without too much fear of damage.

In short, the eMachines G525-902G16Miis very much a mixed bag. While its stunning screen and great usability are easy to like, the limited power and features mean many users may quickly outgrow this machine as their skills develop, so be sure to consider your future needs before buying.

Acer Aspire 5542-304G32Bn - 399

The Aspire 5542-304G32Bn is a budget machine that packs in some unexpected features at a low price point. One of the stand-out features is the inclusion of a Blu-ray drive, a rarity for laptops at this price.

While the 1366 x 768-pixel screen resolution is not enough to take full advantage of the high-definition visuals, images are still crisp and the 15.6-inch LED backlit Super-TFT display provides rich and vibrant colours.

Other features also impress, including the 5-in-1 memory card reader and four USB ports, letting you easily connect external storage and peripherals.

The 320GB hard drive is enough for storing a large number of songs and videos, while leaving space for essential applications.

The only downside is the gaps between each key, which lets in dirt and other debris. The touchpad is one of the largest in this group, although easy to brush while typing. Thankfully there's a button for disabling the pad when not needed.

Overall, the Aspire 5542-304G32Bn is a feature-packed and highly usable laptop that is only let down by limited power and portability.

Not only is the Samsung R530 a great looking laptop, it also boasts great usability, performance and portability - and all at a very competitive price.We very rarely see laptops that have exciting designs at this price point, but the Samsung took us by surprise with its moody red and black lid and mock brushed-aluminium palmrest this is the sort of styling we would expect to see on a laptop costing significantly more.

Build quality is also decent and, although the chassis doesn't feel as substantial as the Acer Aspire 5732Z-443G32Mn, it's quite a bit lighter, making it a better travel companion.

Its battery life is also decent - at 244 minutes - and will keep you productive on the road for quite a while.

The keyboard is excellent, with the typing action proving surprisingly firm and the travel smooth. The touchpad is fast and responsive, and also features Samsung's now trademark lighting effects round the edge, which make it easy to use in low light conditions, such as the cabin on a plane.

The more we used the Samsung R530, the more we liked it. Performance is above average and the design and usability of the machine really endeared it to us.

If that wasn't enough, there's also decent portability chucked in for good measure, making this machine a good choice indeed.

Dell Vostro V13 - 409

The Dell Vostro V13 us arguably the most handsome Dell has ever produced and what's more, you can buy it for under 500.

The Dell Vostro V13 feels great. It's eminently portable at 1.6kg, but the low weight, which edges it towards ultraportable territory, doesn't equate to a flimsy-feeling laptop. The back of the screen feels solid and shock-resistant, and the aluminium casing gives the Dell Vostro V13 a truly premium feel. We're also fans of the all-in-one case design, which looks both lovely and tidy.

The V13's portability isn't all encompassing, though. The battery is a clear weak point for anyone who spends a lot of time away from the mains, or would rather leave the charger behind. With the V13 loaded down by applications, it survived barely two hours on battery power alone; left with the screen on and nothing happening it managed four hours. Fairly respectable, but far short of what's frequently being achieved by cheaper netbooks.

But, performance issues aside, it's stunning to see such a good looking, well-made, cleverly designed laptop available for under 500. Indeed, if you have only the most basic computing needs, you could bag the lowest-end Dell Vostro V13 for a mere 359. Just don't forget to lie about how much it cost.

Lenovo ThinkPad Edge - 499

Lenovo's ThinkPad range has traditionally been aimed at the highend business market, but with a lower price and more accessible style, the Lenovo ThinkPad Edge now opens the brand to a wider market of consumers.

A choice of Intel and AMD processors are available, with the unit we tested being powered by a dual-core AMD chip. Performance of the LenovoThinkPad Edge is in line with the majority of CULV laptops on the market, suiting basic home and office use, but struggling with more demanding multi-tasking.

Graphics performance fares slightly better. The integrated ATI GPU delivers enough power for running complex multimedia presentations, as well as basic photo and video editing. Both VGA and HDMI ports are in place for connecting to larger screens at home or in the office.

The use of a glossy Super-TFT screen shows the consumer leanings of this laptop, as business machines traditionally use less reflective matt-finish panels. The 13.3-inch screen is suitably vibrant, with strong brightness levels, but is not quite as sharp as we would have liked.

By combining the quality and usability of more expensive models with the style and features of a consumer machine, the LenovoThinkPad Edge is another strong addition to the Lenovo range. The low-performance won't suit all needs, but this is a great machine for frequent travel use.

Acer Aspire Timeline 5810T - 560

Although the Acer 5810T boasts a large 15.6 inch screen, its light and thin build means that you won't be bogged down by this laptop when you're taking it out and about. The 5810T's body is an attractive metallic grey made out of plastic that while sturdy, is light enough to keep the weight of the laptop to around 2.4 kg.

The big feature of the 5810T is the large battery life. Acer is keen for this laptop to be used for 'all day computing'. Whilst it won't manage a whole day of heavy use away from a power supply, the 5810T can manage around seven hours which is still a fantastic length for a laptop's battery life.

Video playback, both standard and high-definition was very good, with the images reproduced clearly on the decent screen. The 5810T comes with a HDMI output, so if you have a high-definition TV you can play your video files though that. Although this is hardly an essential feature, it's certainly a nice one to have, and adds to the overall value of the laptop.

Overall this is a nice, reasonably powerful laptop, whose light weight and large battery life means it is a great companion for working on in the great outdoors.

Dell Inspiron 1564 - 587

Dell has had an impressive track record over the past year, delivering one stunning consumer laptop after another. The Dell Inspiron 1564 continues this run of success by implementing cutting-edge technology in this powerful and well-rounded machine.

Built around a processor from Intel's Core i3 range, the Dell Inspiron 1564 among the most powerful entry-level laptops we've seen to date. Effortlessly outperforming all but the similarly specified Samsung R580, multi-tasking with even more demanding software is possible.

Despite using an integrated GPU a graphics technology traditionally associated with limited power Intel's latest onboard chip provides surprisingly powerful 3D performance, allowing high-definition (HD) video and even less demanding games to run with little effort.

The stunning 15.6-inch screen adds to the multimedia usability on offer. It is a very bright panel, and delivers fantastic colour reproduction and sharp images, ensuring movies, photos and games are shown with impressive clarity and vibrancy. While some rivals provide high-speed wireless and fixed access, an older and slower technology is used here. Speeds will suit basic home use, but it is worth bearing in mind before buying.

More pleasingly, storage is excellent. The 500GB hard drive will hold all your family's data with ease. Comprehensive support for flash storage cards is also provided. Continuing Dell's recent run of success, the Dell Inspiron 1564 is an impressively powerful and portable machine. While its limited network connectivity is disappointing, it excels in all other areas, making it one of the best entry-level laptops we've seen this year.

MSI GX740 - 999

We're big fans of the MSI GX740. By making sensible and realistic cuts think Core i5 instead of i7 processor, no Blu-ray drive, lack of full HD screen MSI has managed to deliver a laptop that boasts serious graphical prowess at a very competitive price.

The GX740 also looks great, and we're told by MSI this is the last model to feature the famous style, with the inbound GT660 demonstrating the way of things to come, so if you like the design we'd suggest you get stuck in before it's too late.

The graphical power here is formidable, and the latest games run as smooth as you'd like with settings up high.MSI has been using this design to great effect for quite a few years, it's neither garish nor boring, and we'll be sad to see it go.The relatively low weight and form factor of the GX740 make it very easy to carry around, not something often said about gaming rigs.

The lack of a Full HD screen may bother some, and images may not be sharp enough for the hardcore. The laptop maybe easy to carry, but realistically you'll be sprinting between power points thanks to a truly shocking battery life.

However, the MSI GX740 is one of the best priced, best looking gaming notebooks around. There's plenty of power under the hood for the avid gamer, while the Intel Core i5 processor provides plenty of performance for your average consumer.

Alienware M11x - 1,184

TheAlienware M11x was launched as the world's smallest gaming laptop,offering a unique blend of graphical power and portability. A dedicated Nvidia GeForce GT 335M graphics card has been used featuring 1024MB of video memory and proved stunningly powerful in our benchmark tests.

A 256GB Solid State Drive provides ample space for your content, as well as very fast access to your data. 802.11n Wi-Fi is included and connectivity is comprehensive with VGA, HDMI and a DisplayPort connection all in evidence.

Processing power is courtesy of a Consumer Ultra Low Voltage Intel chip, which is especially resource light on the machine's battery resulting in an impressive 414 minutes of mobile use. The downside is that everyday performance isn't particularly fast.

However, we found the laptop a pleasure to use and certainly fast enough, and we had no issues multi-tasking with various applications.

We are seriously impressed by the Alienware M11x. Not only is it the first of its type, but it succeeds in combining great 3D performance with everyday portability and usability at a competitive price.

Alienware M15x - 1,422

The Alienware M15x is another fantastic gaming system which boasts very strong graphics power, excellent styling and fast everyday performance - and offers it all at an affordable price.

This isn't a laptop you'll want to travel regularly with, however. It weighs a hefty 4.3kg and offers just 164 minutes of battery power with a 9-cell battery on board, and so is much better suited for use as a desktop replacement system.

The 15.6-inch screen features a 1600 x 900-pixel resolution. It is very sharp and provides vivid colours. It isn't the brightest panel we've seen, however, and a shiny Super-TFT coating has been used, creating noticeable reflections in bright light.

The M15x is one of the best gaming laptops we've seen. Its great design is perfectly complemented by decent performance and it's also very reasonably priced not something we can say very often about gaming systems.

Asus G73JH - 1,780

The Asus G73JH is an aggressively and uniquely styled machine that looks fantastic and boasts great performance for gamers. The laptop's striking design with angular lines and tactile matt finish is inspired by the F-117 Nighthawk Stealth Bomber, but there's more purpose to the design than looks alone

Where this machine justifies its price is in gaming performance. The DirectX 11-compatible ATi graphics card provides stunning 3D power for running the latest games and multimedia applications.

The 17.3-inch screen adds to its abilities. It's not the brightest panel around, but colour reproduction is excellent, with contrast especially impressing. Blu-ray movies using the integrated Blu-ray drive and games look great in particular.

We like the G73JH a lot. It's a great looking and uniquely designed machine that provides stunning performance, but for those who are watching the pennies at the moment a lot of us a similar experience albeit with not quite as much style can currently be found for cheaper elsewhere

Rock Xtreme 790 - 1,990

UK-based Rock is well known for its high-performance gaming laptops and offers the latest components housed within generic chassis designs. The Rock Xtreme 790 brings Intel's Core i7 technology to the range and provides truly stunning levels of quad-core power.

Powered by an Intel Core i7 920 processor, performance goes beyond what you would expect from a laptop. Running at 2.66GHz, the CPU is backed by a staggering 6144MB of high-speed DDR3 memory and vastly outperforms every laptop that we've ever tested.

Graphics are provided by a top-of-the range Nvidia GPU for impressive gaming power. In a chassis this large, it is a shame that Rock hasn't used two cards in an SLI configuration, as the extra performance would have perfectly complimented the high-powered quad-core CPU.

The 17-inch Super-TFT screen has a 16:10 aspect ratio, rather than a 16:9 true widescreen design. Quality is excellent nevertheless, with sharp and vibrant images on offer. The panel is not as bright as we'd have liked, but it is still ideal for gaming and home entertainment use.

Overall, the Rock Xtreme 790 is a mixed bag. While performance is outstanding and is backed by strong usability and features, the lack of SLI-graphics is an odd omission considering the machine's size and price.

Acer Aspire 1825 - 585

2010 is already proving to be the year of the tablet PC, with Apple's iPad leading the charge. The Acer Aspire 1825PTZ-413G25n is the latest such convertible, and while the bright and responsive touchscreen adds a fresh layer of usability, this hybrid is unlikely to tempt any iPad fans to convert.

With the screen in a normal upright position, the Acer Aspire 1825PTZ is a typical compact laptop. With a weight of just 1.7kg and a thickness of 35mm, this is an ultraportable laptop that can easily be slipped into a bag.

The chassis itself is firm in all areas, which gives the Acer Aspire 1825PTZ a semi-rugged feel. This laptop likely wouldn't survive a tumble from a desktop, but it can bounce around inside a rucksack all day with little complaint.

3D performance is provided by an integrated Intel graphics card, which lacks its own dedicated video memory and so leeches from the main system memory instead.

As a result, graphical performance is very basic. Watching video and simple photo editing is no problem, but more complex multimedia jobs such as video editing and gaming are beyond the Acer Aspire 1825.

MSI X600 - 594

The MSI X600-055UK is the second machine we've seen from MSI's ultra-slim X-series range, following on from the smaller X340.

With a 15.6-inch screen, this machine is a more rounded package, while still providing excellent mobility. The 15.6-inch screen features a glossy Super-TFT coating, which is reflective in direct sunlight.

You'll find a mid-range ATi Mobility Radeon HD 4330 graphics card supporting the display. It provides the MSI X600-055UK with enough performance to handle basic graphics tasks with ease and you'll even be able to play older games.

As with the smaller X340, this machine uses an Intel CULV (Consumer Ultra Low Voltage) processor, but this is the first system we've seen to feature a CULV Core 2 Duo chip.

Running at 1.6GHz, and backed by 4096MB of DDR2 memory, performance is akin to regular Core 2 Duo processors, proving easily able to carry out intensive tasks and run multiple programs smoothly. Battery life is also good, letting you work for 248 minutes.

Providing excellent performance in a large yet thin and light chassis, the MSI X600 offers a great compromise between size and power. As with much more expensive systems, you'll be able to work on the move without resorting to a smaller and slower form factor

Apple MacBook Air - 1,174

The MacBook Air is an enigma. Its key strength is its lightweight, ultra-thin design making it ideal for carrying around with you. Yet it makes significant sacrifices to achieve this degree of style and portability.

Despite an inevitable speed boost, the Air is still the slowest machine in the Mac range. The entry-level model, with a 120GB hard drive and 2GB of RAM, has a processor running at only 1.86GHz. The high-end version boasts a 128GB solid-state drive instead of a hard drive and a 2.13GHz processor.

A welcome price cut brings the 1.86GHz model down to 1,149 from 1,271, and the 2.13GHz Air reviewed here is now 1,349, down from 1,761.

Although Wi-Fi is still its main means of connecting to networks or the internet, you now get a USB Ethernet adaptor in the box, should you need a wired connection. Trading power for portability and connectivity for convenience means the MacBook Air will never be a machine for everyone, but improved specs at a lower price can only be welcomed.

In short this is a refreshing update for the Apple MacBook Air that just oozes style.

Fujtsu Lifebook P770 - 1,378

The Fujitsu Lifebook P770 is one of the first laptops we've seen with this new technology and we eagerly tested it out to see what difference the new low-voltage Core i7 processor would make. With a weight of just 1.5kg, the Fujitsu Lifebook P770 is an ultraportable laptop that is almost as light as a netbook. It's just as compact too, with a 12.1-inch screen and a chassis that's only 30mm thick. The Fujtsu Lifebook P770 can be slipped into a bag or case and carried around all day without weighing you down.

Intel's new ULV Core i7 processor is a hybrid of the two, which offers buckets of power, but also vastly improved battery life.The Fujitsu Lifebook P770 is powered by this Core i7 620UM processor and the results are truly stunning.

This is easily one of the most powerful low-voltage chips currently available, comparable in performance to Intel's standard Core i3 and top-end Core 2 Duo chips, and we could comfortably multi-task with a number of resource-intensive applications thanks to the dual cores and 4096MB of speedy DDR3 memory.

Toshiba Portege R600-149 - 1,526

Toshiba's Portg R600 range has been a favourite of ours for quite some time, thanks to its great usability and resilient, lightweight design. The Portg R600-149 is the latest model and it's hard to imagine finding a better business machine at this price.

As soon as you pick it up you're struck by just how light it is. At just 820g it feels as if there is nothing inside this machine. With slightly slimmer dimensions than the equally small Fujitsu LifeBook P770, this is a machine built for frequent and comfortable mobile use.

Performance is more pleasing. While this is the only laptop to use Intel's older Core 2 Duo technology, rather than the latest Core i5 and i7 processors, there is ample power on offer for most business use. Only more complex multitasking shows the limits of the older CPU.

The screen is driven by an integrated Intel graphics card, so performance is in line with the Fujitsu LifeBook P770 and falls far behind the Lenovo ThinkPad T410s. Image quality is strong and while colour and contrast are slightly muted, this is a very comfortable screen to work with.

Unless you need the latest cutting-edge features or the longest battery life, this is a fantastic travel partner and we like it a lot.

Images of Russia, during World War II and today:

At Geekosystem, Robert Quigley writes:

Russian photographer Sergey Larenkov is a master of a technique called, alternatively, perspective-matching photography or the fancier computational rephotography, which consists of precisely matching the points-of-view of vintage and modern photographs and exploring what happens where they merge. Since last year, Larenkov has been assembling a series of such photos on World War II

Some Photoshop whizzes have criticized Larenkov's work on the grounds that the mergers are too jarring in their contrasts and could be executed with greater smoothness on his part, but, in the absence of an explanation of his work, I think that's kind of the point: It clearly takes a great deal of patience and technical aptitude to create these photos, and the harshness of imposing war and its devastation on pristine modern European cities works better when it's not too slick.

Browsing through Larenko's gallery, the work is pretty uneven, but in a way that's actually revealing. Some of them just put photos of groups of people from WWII against contemporary backgrounds, or vice versa. It looks sort of like one of those kitschy sepia-tinted photos of your family dressed in old-timey clothes you might get at a theme park. Overwhelmingly, the best images, like those above, blend outdated or obliterated buildings and vehicles into the existing cityscape. It's the materiel, not the men, who matter.

Partly, this is because vintage photos of destroyed cities are just so compelling. This is an underappreciated contribution of Matthew Brady and the other photographers of the American Civil War. They kicked off a new kind of photorealist aesthetic focusing on machines and the worlds destroyed by them. All those strange geometries and fragmented buildings then funnel into the first waves of photographic abstraction. Here are some pictures of Charleston and Fort Sumter (after the allies retook the fort, bombarding it with heavy guns):

Like me, Ta-Nehisi Coates is fascinated by the way that the Civil War is a war driven by and brought to bear on stuff (human beings in the form of slaves and soldiers being just the most visible, contested, and precious kind of stuff) He quotes the historian Daniel Walker Howe:

While the growing of cotton came to dominate economic life in the Lower South, the manufacture of cotton textiles was fueling the industrial revolution on both sides of the Atlantic During the immediate postwar years of 1816 to 1820, cotton constituted 39 percent of U.S. exports; twenty years later the proportion had increased to 59 percent, and the value of the cotton sold overseas in 1836 exceed $71 million. By giving the United States its leading export staple, the workers in the cotton fields enabled the country not only to buy manufactured goods from Europe but also to pay interest on its foreign debt and continue to import more capital to invest in transportation and industry. Much of Atlantic civilization in the nineteenth century was built on the back of the enslaved field hand.

Neil deGrasse Tyson likes to point out how it's a mathematical certainty that the air we breathe and the water we drink passed through the lungs and kidneys (respectively) of everyone who ever lived. Likewise, in these Civil War photos, both the destroyed Southern buildings (one of them a US army fort) and the Northern cannons that destroyed them result from the profits of American slavery. Americans like to think about victories in World War II without thinking about the cities and people destroyed in Russia and dozens of other countries (including Japan, Italy, and Germany) that stand behind that war in no small part because we don't have to live with them, to walk down those streets, to feel those ghosts. But we're haunted all the same.

Why Computers Don't Matter Anymore

This content from: Duct Tape Marketing

An event occurred recently that was widely covered in financial and tech circles, but the significance of which may have been lost on most.

Apple's market cap rose slightly above Microsoft's, making it the largest tech company in the world. Now, market cap is based on current stock price and is a lousy measure of things to come and this is by no means a post about good and bad investments, but to me it marks a point in time that clearly points to the path we're headed for the next decade or so.

Apple, on the verge of extinction in 1996, rose up with laptops, but then bet the farm on hand held devices and applications. Apple now makes the bulk of its revenue from iPods, iPhones and iTunes in fact, it would be safe to suggest that Apple is not really a computer company. Apple built its store right next to the new freeway off ramp (the mobile freeway that is) and has benefited through this location dramatically.

As computers and even web browsers continue to lose significance by yielding ground to mobile devices and applications Apple is positioned to dominate for years to come. In the application world social networks like Facebook will continue to grow, cloud computing via applications will generate far more revenue than operating systems, software and hardware.

What all of this means is that Google must successfully nail a social strategy or even it's mobile plays will cut into it search ad revenue. Microsoft may be in big trouble as it clings to shrinking government and enterprise installations too big to move elsewhere.

Small business can and should seize the opportunity to claim low cost operating efficiencies found in the cloud. Marketers must find effective ways to play in social networks. Resistance to mobile tactics such as location ads, text messaging, and mobile applications must erode as they become the preferred method of content and information consumption.
