Fast, easy tricks to avoid spending too much while shopping:

CNN has an excellent piece that distills research from behavioral economics and cognitive biases to help us avoid overspending. My takeaways are:

Buying a lot in one store can decrease your sensitivity to the pain of cost, says Loewenstein. "You hit the what-the-heck effect: You've spent $200; what's another $20 for a T-shirt?" He recommends going to various stores for different purchases.

We overreact to discounts:

"Even psychologists confess that they've been seduced." The anticipation of getting a good deal, says Shell, is what drives us toward the cash register, not the object itself -- and as a result, we end up with stuff we don't particularly want.

Use cash, not credit cards:

"When you pay in cash, you see your wallet getting thinner," says Dan Ariely, Ph.D., professor of behavioral economics at Duke University. But when you use a credit card, the spending is abstract, "and that makes you trigger-happy."

...Using cash is the number one antidote to overspending, according to experts. 

Your mood can affect how much you're willing to pay for things:

...participants view either a sad video (a clip from "The Champ," in which a boy cries at the side of his dying father) or an emotionally neutral one (about the Great Barrier Reef).

Afterward, she asked how much they'd be willing to spend on a sporty water bottle. Those who watched the poignant film offered almost 300 percent more.

Anything that taps willpower can affect your spending:

"Our ability to fight temptation weakens, almost as if we get tired," says Duke's Dan Ariely. After engaging in activities that require willpower, you won't have as much energy left for other challenges, explains Kathleen D. Vohs, Ph.D., assistant professor of marketing at the University of Minnesota. So if you're using every ounce of discipline at the food court because you're on a diet, or you're trying to quit smoking, you'll be less able to pass up a pair of pumps in a display window.

One of the researchers cited, Dan Ariely, has written two wonderful books about similar quirks of human behavior:  Predictably Irrational and The Upside of Irrationality: The Unexpected Benefits of Defying Logic. I highly recommend them both.

Blog Post: Erro 0x80070002 ao acessar compartilhamentos remotos.

By: [Marcelo Chang] / Technical Reviewer: [Daniel Mauser]

O cen�rio descrito � um servidor Windows 2008 Enterprise SP2, que ao tentar mapear uma unidade de rede pelo Windows Explorer apresenta a seguinte mensagem de erro:

"Error Code: 0x80070002 The system cannot find the file specified."


Ao tentar mapear pelo command prompt a seguinte mensagem � mostrada:

C:\>net use * \\servidor\share

The Workstation service has not been started.

More help is available by typing NET HELPMSG 2138.

Verifica��es b�sicas

As primeiras a��es neste caso, foi verificar os eventos relevantes atrav�s do Event Viewer, mas nada que indicasse a origem do problema. Validar e instalar atualiza��es para SMB, TCPIP, Redirector. Foi verificado tamb�m que o "Client for Microsoft Networks? estava realmente instalado e ?ligado? na placa de rede. Ao ser capturado o tr�fego de rede atrav�s do Network Monitor foi verificado que n�o havia tr�fego gerado para o destino. Por isso, o foco do caso foi tentar resolver o erro ?The Workstation service has not been started?.

O que � o Servi�o ?Workstation??

Para ambos os pedidos de arquivos locais e arquivos remotos ou pedidos de impress�o estes ser�o encaminhados atrav�s do servi�o ?Workstation?. Este servi�o determina onde o recurso est� localizado e em seguida, encaminha o pedido para o sistema de arquivos local ou para os componentes de rede. Quando o servi�o ?Workstation? � interrompido, todos os pedidos ser�o assumidos como solicita��es locais.

A partir da� foram feitas valida��es nas configura��es do Workstation atrav�s da chave do registro.


1. Abra o Regedit e v� at� o caminho: ?HKEY_LOCAL_MACHINE\SYSTEM\CurrentControISet\Control\NetworkProvider\Order"

2. O "ProviderOrder" contem neste servidor somente o valor "hgfs"


3. Valido em outro Servidor Windows Server 2008 a mesma Chave. O valor entrado � diferente.


4. A chave "ProvideOrder" cont�m: "vmhgfs,hgfs,RDPNP,LanmanWorkstation"

5. Copiado o valor do deste servidor para o servidor que est� apresentando problemas.

6. N�o h� a necessidade de reiniciar o servidor.

7. Feito os testes usando o net use e o Windows Explorer.

C:\>net use * \\servidor\share

Drive Y: is now connected to \\servidor\share.

8. Testado com UNC \\servername2\data$

Clever Sense Launches Alfred: Personalized Local Recommendations With A Single Tap

Back in June I wrote about Clever Sense, a startup that's looking to take a different approach to restaurant and other local recommendations. Led by CEO Babak Pahlavan, the service has a strong emphasis on algorithms that are used to customize its�suggestions for each user�(the company is led by Stanford PH.D. grads, and is advised by Professor Jeff Ullman, who was the Ph.D. advisor for Sergey Brin way back when). Their application, called Seymour, was supposed to launch tomorrow morning in conjunction with Fortune's Brainstorm conference, but it hit a somewhat fortuitous snag: CleverSense decided to release it early on the App Store under a different name (Alfred) as a sort of trial run. And then the app managed to acquire 20,000 users in the last two weeks ? so Clever Sense decided to ditch Seymour and stick the the app they've already released.�You can grab it on the App Store right here.


Skype 5.3 for Windows released, improves mobile video call quality

Version 5.3 of Skype for Windows has just been released, with the main emphasis of the new release being improved call quality, and the quality of video received by mobile Skype users. Presumably one party of the video call must be using Skype for Windows 5.3, though.

Beyond improved call quality, not much has changed. You can now see your friends' presence icons when contact cards are collapsed, and the topic editing button is now always visible on the conversation header. For a complete list of changes, hit up the Skype Garage blog.

New software uses facial recognition to defend against prying eyes

Having the right programs and hardware to keep the information on your display safe from prying eyes is never a bad idea, and new software from Oculis Labs offers a very interesting take on how to do just that. It's called PrivateEye, and it utilizes facial recognition to automatically pixelate the contents of your display when you look away.

If you step away from your system and someone else decides to sit down and poke around, PrivateEye will present a confusing jumble of garbled text. It'll even notify you if someone tries to peek over your shoulder -- and display a picture of your peeping Tom, throw up an alert, or sound an alarm.

Check out the video embed after the break, and share your thoughts in the comments!

iPhone games over-indexing for monthly usage says Nielsen

Apple-owning mobile gamers spend 14.7 hours a month playing, but it's a different story for BlackBerry

The average iPhone gamer spends nearly twice as much time playing every month as the industry average for smartphone gamers, according to new research published by Nielsen in the US. Its latest survey finds that iPhone gamers play for an average for 14.7 hours a month, ahead of Android gamers' 9.3 hours a month.

Both are above the industry average of 7.8 hours, since other devices under-index considerably. Windows Phone gamers spend 4.7 hours a month playing according to Nielsen, while feature phone and BlackBerry owners spend 4.5 hours a month.

Those figures won't make for pleasant reading at Microsoft, which has made the Xbox Live community a key selling point for Windows Phone 7 devices. There is some better news for the company: its users are the most likely to download games. Of WP7 users who have played a game in the last 30 days, 70% downloaded it, versus 69% for iPhone and 66% for Android.

It's a different story for feature phone owners, with 54% playing games preloaded on their devices, while 28% have downloaded them. BlackBerry scores even worse on this metric: according to Nielsen, 24% of BlackBerry gamers are playing downloaded games, versus 63% playing preloaded titles.

Developers piling into the emerging sector of mobile web gaming may be encouraged by the fact that 10% of iPhone and Android users say they are playing web-based games on their devices.

Overall, games come out strongly from Nielsen's research. Of people who have downloaded at least one app in the last month, 64% say they have played games in that period. That's the most popular category ahead of weather (60%), social networking (56%), the slightly awkward catch-all category of maps/navigation/search (51%) and music (44%).

The research also finds that 93% of app downloaders are willing to pay for the games that they play, compared to 76% for news. Not that this is a reason for publishers of news apps to be glum ? it's certainly a conversion rate they can work with.

Nielsen's survey will bolster the credibility of mobile gaming ? on certain platforms at least ?�with traditional games publishers. It comes hot on the heels of analyst firm Gartner's prediction that by 2015, mobile gaming will account for 20% of global games software sales.

"As the popularity of smartphones and tablets continues to expand, gaming will remain a key component in the use of these devices," said the company's principal research analyst Tuong Nguyen. "Although they are never used primarily for gaming, mobile games are the most downloaded application category across most application stores."

Golf Connection: Web-Connected Golf Simulator (Video)

Konami isn't just a video game maker. The company is also in the business of producing amusement machines (mainly for the Japanese market), and recently showcased its newest model: the aptly named Golf Connection [JP]. "Virtual golf simulators" like this aren't new, but Konami's version (which is based on a high-speed camera and two sensors) has a few interesting selling points.
