Mobile ads to push Twitter ad revenue near $1 billion in 2014: report

(Reuters) - Twitter will generate nearly $1 billion in ad revenue next year due to a surge in mobilea dvertising on its Web microblogging service, according to a report released on Wednesday.

Mobile ads will account for roughly half of Twitter's advertising revenue this year and will make up more than 60 percent of the company's ad revenue by 2015 according to research firm eMarketer.



The increasing popularity of Twitter's mobile ads - introduced in March 2012 - caused eMarketer to raise its 2014 ad revenue estimates for Twitter to $950 million, versus its previous estimate of roughly $800 million. Twitters' ad revenue this year will total $582.8 million, according to the report, roughly double what it was in 2012.

Twitter, which allows people to share 140-character messages on its online service, is privately held and does not disclose financial results.

With more than 200 million monthly active users, Twitter is among the Web's most popular social networking services, along with Facebook Inc, and is expected by analysts to float shares to the public within two years.

As consumers increasingly access the Web on smartphones, mobile ads have become increasingly important to the businesses of Web companies such as Facebook and Google Inc. Facebook said in January that its mobile ad revenue doubled from the third quarter to the fourth quarter, representing roughly 23 percent of its $1.33 billion in fourth-quarter ad revenue.

"Twitter has ultimately benefited from the increased focus on mobile by competitors like Googleand Facebook, which have both expanded their own mobile ad offerings and worked to convince advertisers to shift dollars to mobile devices," eMarketer said on Wednesday.

eMarketer said its revenue forecasts are based on analysis of reports that track media buying trends, Twitter usage data and interviews with executives at advertising agencies, online publishers and others.

Samsung Galaxy S4 vs. Nexus 4

Nexus and Galaxy. The two brands represent opposing ends of the Android spectrum. Nexus devices have always been Google’s pure, untarnished vision of its platform. Samsung’s wildly-successful Galaxy devices, meanwhile, still use Android, but also threaten to overshadow it. What happens when you put the best of each side-by-side? Read on, as we compare the specs and features of the Samsung Galaxy S4 and LG Nexus 4

Size

 The Nexus 4 is a bit shorter, narrower, and thicker. But – when you look at smaller rivals like the iPhone 5, or phablets like the Galaxy Note II – you realize that the size differences here are pretty minor.

Build

It’s easy to poo-poo on Samsung’s use of plastic, but you could also argue that it allows the company to focus more of its expenses on things like 1080p displays and octa-core processors.
The front and back of the Nexus 4, meanwhile, are made of Gorilla Glass. LG helpfully placed a rubbery band around the phone’s edges, allowing for an easier and more comfortable grip.
That extra grip is a good thing, considering that – no matter how strong Gorilla Glass is – it’s going to be more prone than plastic to cracks and scratches.
Both sets of materials have their pros and cons, and this is probably one of the first big areas you’ll want to think about when deciding between these two handsets.

Weight

It’s impressive that LG managed to make the glass Nexus 4 only 9 g (0.32 oz.) heavier than the plastic Galaxy S4. We suspect the GS4’s larger battery (see below) has something to do with that.

Display

The Galaxy S4’s display is both larger and sharper than the Nexus 4’s screen.
Once you get to a certain level of sharpness (probably around 300 pixels per inch), cramming in more pixels ceases to play as big of a part. Both of these screens are razor sharp, and your eyes won’t likely see any individual pixels on either one.
That means the display technology will play a bigger part. The Galaxy S4’s Super AMOLED has blacker blacks (technically no light comes through black pixels) but hyper-saturated colors. The Nexus 4’s IPS display, meanwhile, leads to better viewing angles and more accurate color reproduction.

Processor

The Nexus 4’s Snapdragon S4 Pro chip is a beast. Ditto for both versions of the Galaxy S4: the North American version’s quad core Snapdragon 600 and the international version’s octa core Exynos chip.
In terms of benchmarks, the Galaxy S4 is going to beat the Nexus 4. In terms of experience, though, you probably won’t see much of a difference. All three processors should blaze through just about any app you throw at them.

RAM

 Our two entrants are tied up, each with 2 GB of RAM.

Storage

This is a big-time advantage for the Galaxy S4. The 8 GB offered for the entry-level Nexus 4 isn’t a lot. Add to that the Nexus 4’s lack of an SD card slot, and you could find yourself cramped for free space.
Fortunately, the 16 GB edition of the Nexus 4 only costs US$50 more than the 8GB version.
There’s also the matter of off-contract pricing. Namely, the Nexus 4 was built for it, and the Galaxy S4 wasn’t. Carriers haven’t yet announced pricing for the GS4, but you can bank on around US$200 or so on-contract. The Nexus 4 starts at $300 off-contract.

Wireless

 

Here’s another tough call, as there’s no LTE for the Nexus 4. It does support HPSA+, which offers faster than 3G speeds ... but LTE it is not. You’ll also need to sign up with a GSM carrier for the Nexus 4, as CDMA (that's Verizon and Sprint in the U.S.) networks aren’t supported.

Cameras

 

Megapixels make for an easy-to-read metric for these graphics, but they make for a far-from-perfect representation of camera quality. We’ve yet to put the Galaxy S4 through the paces, but you don’t have to worry about the Nexus 4’s shooter. It takes great shots, and can easily replace a point-and-shoot.

Battery

 

Here’s another stat that isn’t an absolute indicator of experience, as many other factors determine actual battery life.
The Nexus 4 offers solid battery life: under typical use, it will easily last a full day. Does that mean the Galaxy S4 – with more capacity – will get better uptime? Maybe, maybe not. When you consider that it has LTE and a display with over a million extra pixels, it may need that extra capacity to match the Nexus 4’s uptime.

Software

 

One of the most surprising things about the Galaxy S4 is that it will ship with the latest version of Android, 4.2.2.
But you’d be forgiven for thinking the Galaxy S4 runs its own operating system. Samsung is increasingly hiding its Android roots under a heavy layer of “TouchWiz” – complete with a bevy of crazy features (facial-recogntion scrolling, fitness tracking, photos with accompanying audio clips ...).
Meanwhile, the Nexus 4 – like all Nexus devices – runs “pure Google,” or stock Android. What you see is exactly what Android’s creators and designers intended - and nothing more.
Though the two phones run the same version of Android right now, that may not last long. Without manufacturer skins or carrier crapware, the Nexus 4 will be first to receive future Android updates. Samsung has improved its support for updates, but GS4 owners will have to wait much longer for Key Lime Pie (or whatever the next major version is called) than Nexus 4 owners will.

Technology Lab / Information Technology Why Microsoft’s new Office 2013 license may send users to Google Docs

If you buy a perpetual retail license for Office 2013, it will be locked to the computer you first install it on, forever. Buy a new PC and you won't be allowed to install your existing copy of Office on it, even if you wipe the disk of the old PC. You'll have to splurge for a new one.

This is a change in policy from Office 2010. Office 2010 permitted a single transition from one PC to a new one. It's not, however, an entirely new policy: OEM pre-installed versions of Office (and Windows) are similarly tied to their (OEM) hardware and can't migrate. Adam Turner at The Age first pressed Microsoft for clarification over what its "single PC" constraint actually meant, and he noted the newly aligned OEM and retail licenses.

It's difficult to see the wisdom in this change. It's not a big change, but it's not a nice one, either.

Retail sales make up a minority of the Office business. Microsoft doesn't habitually report the exact level of retail sales, but we can perhaps make estimates based on the information the company does provide.

The Microsoft Business Division (MBD), the reporting group within the company that includes Office, Exchange, SharePoint, Dynamics, and Lync, reported last quarter that 60 percent of its revenue is from multi-year subscriptions—Software Assurance plans. The remaining 40 percent is what Microsoft calls "transactional;" one-off purchases, encompassing both OEM preinstalls and boxed copies bought online or in bricks-and-mortar stores.

The company's 2012 annual report also has some useful information. The report says that in its 2012 financial year, 80 percent of its sales were to businesses, 20 percent to consumers. A reasonable inference is that business sales include essentially all of the multi-year revenue (as it is only this year that Microsoft offered a consumer-oriented subscription, Office 365 Home Premium), and about half of the transactional revenue.

In the annual report, Microsoft also emphasizes that while the 80 percent of business revenue is relatively consistent, driven primarily by the number of information workers, the 20 percent is much more dependent on the broader level of PC sales and product launches. This in turn suggests that a significant proportion of it is made up of OEM sales, for which there's been no relevant licensing change.

One final data point: Windows division reports that around 75-80 percent of its revenue comes from OEM sales.

Even optimistically, retail revenue is unlikely to account for more than 20 percent of MBD revenue, and it might be a lot less. If MBD's transactional revenue has the same level of OEM sales as Windows, it would mean that retail sales were no more than 10 percent of revenue. It's a nice business, but it's not Microsoft's major money-maker, and it's not representative of the majority of Office customers.

It's spectacularly unlikely that this licensing change is going to increase that revenue in any meaningful way. It's also unlikely to make any material difference to many people. The only people who would be impacted are those who migrate software between systems, and while that's common among enthusiasts, it's probably not mainstream: the mainstream solution is to buy an OEM preinstall license, or buy retail Office alongside a new PC, use that PC for 5 years (or more) until it no longer works, then throw it away and repeat the process.

Transplanting software from one machine to another (or invoking Ship of Theseus-like questions over when an upgraded PC becomes a new one) is something for enthusiasts—perhaps explaining why the OEM license restrictions have for the most part been shrugged off—and even if Microsoft managed to generate some extra sales to those enthusiasts, it's never going to amount to very much.

But that is arguably missing the point. The software giant is penalizing a small, typically vocal group of users and provoking many column inches of complaint. This is a change that looks bad. It makes Microsoft appear petty and small-minded, determined to wring every last dollar from its customer base. And while that may in fact be the case, doing so in such a brazen manner does nothing more than get people's backs up.

The underlying reason for the change is almost certainly not any direct revenue generated by additional sales. Rather, it's yet another incentive to buy an Office 365 Home Premium subscription. The $99 a year subscription lets you use Office 2013 on up to five PCs, and those licenses float; you can decommission old PCs and move licenses to new ones as necessary. That's the carrot; the stick is the price hike and additional restrictions on perpetual licenses.

The problem is that there are plenty of customers who reject the subscription model out of hand, either because they find an overt rental model offensive or because they don't place much value in having the current version of the software and hence find occasional perpetual licenses to be more cost effective. The retail license change doesn't fundamentally alter that calculus for those users. It just makes clear that Microsoft doesn't really like such users.

So they probably won't flock to Office 365. What they might well do instead is download LibreOffice 4 or switch to Google Docs—moves that hurt Microsoft far more than simply moving an Office install from an old computer to a new one. Those enthusiasts could take the mass market with them. It's happened before, with Firefox and Chrome. It can happen again to Office. Licensing changes that alienate users make that only more likely to happen.

The world's first completely artificial human

The British roboticist designers are made the world's first completely artificial human. According to creators, He's the worlds first bionic man. Comprising artificial organs, Synthetic blood, robotic limbs and a human face. And as if that's not enough, he can speak and also listen and artificial organs including a pancreas, kidney, spleen, and trachea. The artificial human was created for a Channel 4 documentary called How to Build a Bionic Man. The project cost £640k ie.
$1 million. and showcases the latest achievements and advancements in bionic technology and prosthetic science. “Strictly speaking, he’s not a robot,” Channel 4’s science editor Tom Clarke says in a report (below) about the bionic creation. “His parts aren’t designed to work together, but each one either is, or soon could be, part of a living human being.” Rex’s two-meter-tall ‘body’, built with currently available bionic and prosthetic technology, includes a prosthetic face, hands, hips, knees and feet as well as cochlear implants which enable him to hear and retinal implants that allow him to sense objects in front of him. Speech synthesis technology means Rex can make sense of

simple statements and even respond to some questions.
Artificial blood pumps through his artificial organs, which include a heart, kidney and pancreas. He also has a spleen and trachea. The stomach is missing, but one imagines it won’t be too long before the science boffins fix him up with one of those, too.

“Throughout history people have always sought to enhance themselves to overcome disabilities or to become bigger, better, stronger and faster,” Clare Matterson of the Wellcome Trust, which is funding the exhibition, Please watch video.

Nanotechnology

Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. Nanotechnology is not just a new field of science and engineering, but a new way of looking at and studying .
How Nanotechnology Is Started
 The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Over a decade later, in his explorations of ultraprecision machining, Professor Norio Taniguchi coined the term nanotechnology. It wasn't until 1981, with the development of the scanning tunneling microscope that could "see" individual atoms, that modern nanotechnology began.
Fundamental Concept  

It’s hard to imagine just how small nanotechnology is. One nanometer is a billionth of a meter, or 10^-9 of a meter. Here are a few illustrative examples:

• There are 25,400,000 nanometers in an inch
• A sheet of newspaper is about 100,000 nanometers thick
• On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth

Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.

But something as small as an atom is impossible to see with the naked eye. In fact, it’s impossible to see with the microscopes typically used in a high school science classes. The microscopes needed to see things at the nanoscale were invented relatively recently—about 30 years ago.

Once scientists had the right tools, such as the scanning tunneling microscope (STM) and the atomic force microscope (AFM), the age of nanotechnology was born.

Although modern nanoscience and nanotechnology are quite new, nanoscale materials were used for centuries. Alternate-sized gold and silver particles created colors in the stained glass windows of medieval churches hundreds of years ago. The artists back then just didn’t know that the process they used to create these beautiful works of art actually led to changes in the composition of the materials they were working with.

Today's scientists and engineers are finding a wide variety of ways to deliberately make materials at the nanoscale to take advantage of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts.

Albert Einstein

Albert Einstein (1879-1955), German-born American physicist and Nobel laureate, best known as the creator of the special and general theories of relativity and for his bold hypothesis concerning the particle nature of light. He is perhaps the most well-known scientist of the 20th century.Einstein was born in Ulm on March 14, 1879, and spent his youth in Munich, where his family owned a small shop that manufactured electric machinery. He did not talk until the age of three, but even as a youth he showed a brilliant curiosity about nature and an ability to understand difficult mathematical concepts. At the age of 12 he taught himself Euclidean geometry.
Einstein hated the dull regimentation and unimaginative spirit of school in Munich. When repeated business failure led the family to leave Germany for Milan, Italy, Einstein, who was then 15 years old, used the opportunity to withdraw from the school. He spent a year with his parents in Milan, and when it became clear that he would have to make his own way in the world, he finished secondary school in Aarau, Switzerland, and entered the Swiss Federal Institute of Technology in Zürich. Einstein did not enjoy the methods of instruction there. He often cut classes and used the time to study physics on his own or to play his beloved violin. He passed his examinations and graduated in 1900 by studying the notes of a classmate. His professors did not think highly of him and would not recommend him for a university position.

Amino Acid

Amino Acids, important class of organic compounds that contain both the amino (8NH₂) and carboxyl (8COOH) groups. Of these acids, 20 serve as the building blocks of proteins (see Protein). Known as the standard, or alpha, amino acids, they comprise alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. All 20 are constructed according to a general formula:

As the formula shows, the amino and carboxyl groups are both attached to a single carbon atom, which is called the alpha carbon atom. Attached to the carbon atom is a variable group (R); it is in their R groups that the molecules of the 20 standard amino acids differ from one another. In the simplest of the acids, glycine, the R consists of a single hydrogen atom. Other amino acids have more complex R groups that contain carbon as well as hydrogen and may include oxygen, nitrogen, or sulfur, as well.

When a living cell makes protein, the carboxyl group of one amino acid is linked to the amino group of another to form a peptide bond. The carboxyl group of the second amino acid is similarly linked to the amino group of a third, and so on, until a long chain is produced. This chainlike molecule, which may contain from 50 to several hundred amino acid subunits, is called a polypeptide. A protein may be formed of a single polypeptide chain, or it may consist of several such chains held together by weak molecular bonds. Each protein is formed according to a precise set of instructions contained within the nucleic acid (see Nucleic Acids), which is the genetic material of the cell. These instructions determine which of the 20 standard amino acids are to be incorporated into the protein, and in what sequence. The R groups of the amino acid subunits determine the final shape of the protein and its chemical properties; an extraordinary variety of proteins can be produced from the same 20 subunits.

The standard amino acids serve as raw materials for the manufacture of many other cellular products, including hormones (see Hormone) and pigments. In addition, several of these amino acids are key intermediates in cellular metabolism (see Metabolism).

Most plants and microorganisms are able to use inorganic compounds to make all the amino acids they require for normal growth. Animals, however, must obtain some of the standard amino acids from their diet in order to survive; these particular amino acids are called essential. Essential amino acids for humans include lysine, tryptophan, valine, histidine, leucine, isoleucine, phenylalanine, threonine, methionine, and arginine. They are found in adequate amounts in protein-rich foods from animal sources or in carefully chosen combinations of plant proteins.

In addition to the amino acids that form proteins, more than 150 other amino acids have been found in nature, including some that have the carboxyl and amino groups attached to separate carbon atoms. These unusually structured amino acids are most often found in fungi and higher plants.
