By NarayanaPrakash

Does dialog box works on all kind of shells? I am using korn shell in Linux .
For me dialog is not working 🙂 is there any particular syntax or do we need to have particular OS version or shell env?

Code:

 

#!/bin/ksh

dialog --title "create file" 

--backtitle "shell script practice" 

--yesno "Are you sure you want to create "/tmp/test.txt"?" 7 60

# Get exit status

# 0 means user hit [yes] button.

# 1 means user hit [no] button.

# 255 means user hit [Esc] key.

response=$?

case $response in

0) echo "File created.";;

1) echo "File not reated.";;

255) echo "[ESC] key pressed.";;

Will The Public Start Using The New Nexus 7 From Google?

July 24, 2013 Bartle Doo Leave a comment

By Ewan Spence, Contributor

Google’s expected announcement today of the new Nexus 7, it carried on with the narrative that there are two tablet ecosystems, finely balanced, but with the improved specifications and new OS in the Nexus 7, the Android platform is sneaking ahead. That’s a good way to lay it out, but the usage numbers are less kind to the Android platform. …read more

Problem with Privoxy and Tor

July 24, 2013 Bartle Doo Leave a comment

By Dr. Nick

Greetings,

I use Debian Wheezy as an OS and I have already downloaded the Tor Browser-Bundle, which works fine.

As soon as a start privoxy and set the proxy to: 127.0.0.1:8118 (socks4) in the tor browser (edit–>pref–>advanced–>settings—>http-proxy) I always get a connection refused. I did everything that I can find on the privoxy troubleshooting page, but it won’t help.

I added this line to the /etc/privoxy/config to chain privoxy to tor, doesn’t work either.

forward-socks4a / 127.0.0.1:9050 .

tried this too

forward-socks5 / 127.0.0.1:9050 .

I mostly get the message “refused by proxy server” when connecting to a website like google or something.

anyone have a suggestion what could be wrong?

$32 Million In 31 Days?

By Karsten Strauss, Forbes Staff

On paper it seems an almost impossible goal: raise $32 million in a month through a crowdfunding campaign in order to roll out a new high-end cellular phone. But that’s exactly what UK-based technology company, Canonical, is looking to do. The company created Ubuntu (pronounced Oo-Boon-Too), a Linux-based operating system that integrates PC, tablet, mobile and television formats. Its newest smartphone project – which is called The Ubuntu Edge – will be its first piece of phone hardware, if it’s funded. The phone will boast a 4.5-inch sapphire crystal screen, 720p screen with a multi-core processor, 4GB of RAM, dual LTE antennas and 128GB of storage. The Edge will run Ubuntu’s OS as well as Android, according to its campaign pitch. Price? You can buy one through the crowdfunding campaign for $830. (See Canonical’s pitch of The Ubuntu Edge below) But can the company reach its $32 million mark? As of July 23, the campaign had raised almost $3.5 million on Indiegogo. The best reason to believe that the company can is Canonical’s 39-year-old CEO and founder, Mark Shuttleworth. The successful, South African serial entrepreneur was not named one of FORBES’ “12 Most Disruptive Names In Business” this year for nothing. In a move akin to charging a heard of oncoming bulls, Shuttleworth has puts his company head to head with deeply entrenched competitors by crafting a third operating system that plays in multiple device categories. In the mobile space, Ubuntu is up against Apple’s OS and Google’s Android, among others. In the PC realm – where Shuttleworth estimates some 20 million use Ubuntu– Microsoft is king. The company also has ambitions in the TV space. Shuttleworth’s obviously not one to do things the easy way (his idea of vacation spots have included Antarctica and the International Space Station). …read more

It’s a New (Virtual) World with Windows Server 2012 R2

To read this article in full or to leave a comment, please click here

Microsoft recently rolled out Windows Server 2012 R2 Preview. The update for Microsoft’s flagship server OS includes a number of features to improve and enhance managing virtual servers with Windows Server 2012.

Virtual servers are crucial for small and medium businesses. Most SMBs don’t have an IT department or data center to work with and need tools that simplify management and allow them to operate an entire IT infrastructure from a single box. Virtual servers allow businesses to maximize the value and productivity of their investment in hardware.

With Windows Server 2012 R2 Preview, Microsoft has streamlined the performance of Hyper-V. Replication between virtual servers is faster, and more frequent, and Microsoft has added more disaster recovery options. The new Hyper-V also allows you to assign QoS (quality of service) to prioritize disk access for virtual machines that need it more, such as a database server.

Linux VMs

One of the best improvements in Windows Server 2012 R2, though, is the enhanced support for Linux virtual machines. Previous versions of Hyper-V have technically supported Linux, but the capabilities were very limited.

China's Alibaba Group taps smart TVs for online shopping

To read this article in full or to leave a comment, please click here

Chinese e-commerce giant Alibaba Group plans to enter the country’s smart TV industry with a set-top box product for streamlining online shopping on big screen televisions.

The set-top box runs a Linux-based OS and can stream television shows and movies, and play games and music via a remote control or a user’s own smartphone. What sets the device apart from some rival products, though, is its focus on online shopping. Accessing Alibaba’s shopping services through the box, registered users can buy the products they view in two steps: confirming they want the product, and paying for it, said Yu Ce, vice president for Alibaba Group.

“This complete process will make the shopping very simple, and suitable for a large number of consumers, especially for older people, children, and people that use TVs,” he said.

Products sold on the TVs, however, won’t be the same as those typically offered on Alibaba’s online shopping sites Taobao Marketplace and Tmall. Instead, the set-top box will initially feature discount deals on products from Alibaba’s group-buying site Juhuasuan.

What Microsoft's Earnings Report Means for Small Businesses

To read this article in full or to leave a comment, please click here

Microsoft unveiled its earnings for Q4 2013 on Friday, and the results left some investors uneasy. What matters on Wall Street, however, isn’t the same as what matters on Main Street, so small and medium businesses need to analyze the news through a different lens.

Microsoft actually had a decent quarter to cap off a very successful fiscal 2013. Revenue for Q4 was up 10 percent over Q4 2012, and profit was almost $5 billion (USD) compared to a $492 million loss in the same quarter last year. Revenue was also up for the year, and Microsoft profit was nearly 30 percent higher than 2012.

Despite declining PC sales, adoption of Windows 8 is on pace with that of its predecessor. There has been some backlash over the dramatic redesign of Windows 8, and Microsoft’s attempt to convert the OS to a touch-based interface, but most of the major complaints are addressed with the Windows 8.1 update, which will be officially available later this year.

Another silver lining from the Microsoft earnings report is the fact that the Business Division and Server and Tools units both reported solid increases in both revenue and profit over the previous year. Office 365 is a cost-effective way for SMBs to acquire Microsoft Office, along with hosted Exchange and SharePoint, and it has quickly grown into a $1.5 billion source of revenue for Microsoft.

HP, NEC to develop next-generation x86 servers

To read this article in full or to leave a comment, please click here

Hewlett Packard and Japan’s NEC will expand their existing partnership to develop high-end x86-based servers for cloud and Web applications.

The companies said Thursday they will team up to accelerate research on HP’s next generation of blade-based server systems, which the U.S. company is gradually introducing alongside its traditional Itanium Unix-based servers. They said their focus will be on creating x86 hardware that can run with the same reliability as the Unix products, which can then be employed in mission-critical roles running today’s social networks, mobile applications and cloud-based services.

HP is trying to catch up to rivals such as Amazon Web Services in the growing market for cloud services, while also stay competitive in hardware amid a general shift away from Unix. The company announced a strategy to pursue a hybrid cloud approach last year, based on a solution it is calling HP Converged Cloud. Last month it announced a new operating system for cloud computing, HP Cloud OS, built on the open-source hosting software platform OpenStack, but said initially the new OS will only run on its own hardware.

The new partnership will aim to speed up the development of HP’s Project Odyssey, which it first announced in 2011. The project is an attempt to integrate x86 server blades running Windows or Linux with its Itanium-based server lineup based on Unix. NEC said the companies will specifically focus on a system that HP has been developing for years called “DragonHawk,” which is supposed to be able to incorporate both types of servers into a single cabinet but has been slow to materialize.

Encrypt shell script

To read this article in full or to leave a comment, please click here

By millan

Hi,

We have some scripts which will run in other project..So the requirement is that we dont want that they should see our code though they can run it. I have done some searching about how to encrypt the shell script and found SHC utillity as the answer.

Can anybody please suggest how will i do it.

And is it dependent on the OS? What i mean here is, if i encrypt the scripts in solaris after installing SHC, will these run in HPux or Linux even though no SHC installed there?Or do you see any disadvantage of using this utillity.

Thanks in advance.

Microsoft was wrong: Tablets are not PCs. So now what?

July 19, 2013 Bartle Doo Leave a comment

The three most important device platform vendors—Apple, Google, and Microsoft—have each consolidated their mobile and desktop operating systems under a single product leader. This could be taken as a hint of a new industry trend, where each company is looking to consolidate onto single unified OS for all types of devices.

This would be a colossal mistake. The market has shown conclusively that people don’t want tablets that work like PCs. They’re different. Any attempt to force them together will fail.

But blending the best characteristics of each type of platform? That just might work.

Two points of view

Microsoft has always tried to insist that the tablet is a kind of PC. Microsoft created a variant of Windows XP for tablets way back in 2002. Its strategy around Windows 8 and Windows RT was summed up by then-Windows chief Steven Sinofsky’s “no compromises” rhetoric.

Infiltration complete: Google's Chrome app launcher lands on Windows

July 19, 2013 Bartle Doo Leave a comment

It’s still early days for packaged apps, but there are a number you can try out, such as a

After months of behind-the-scenes teases, Google appears to have quietly introduced the Chrome App Launcher in the stable version of Chrome for Windows. The Chrome OS feature—ported over to the Chrome for Windows developer channel in February—wasn’t available through a search of the Chrome Web Store or advertised on the site’s front page at this writing, but Windows users can install it now by navigating directly to the Chrome App Launcher page inside Chrome’s app store.

First spotted by Engadget, the new feature is Google’s incursion into the desktop PC, creating a self-sufficient Chrome ecosystem inside Microsoft’s OS. The Chrome App Launcher lets you directly fire up any Chrome Web app or packaged app right from the Windows taskbar—even when Chrome itself isn’t running.

Packaged apps are HTML 5-based standalone desktop apps based on Chrome that don’t look anything like your Web browser. There are no tabs, URL address bars, or bookmarks, but these apps do rely on Chrome’s underlying infrastructure and are installed via the Chrome Web Store.

It’s still early days for packaged apps, but there are a number you can try out, such as a generic text editor and an IRC client, as well as known quantities like Cut the Rope, the Economist, and Weather Bug. For a list of interesting packaged apps to test see this post from Pocketables.

Lenovo drops Yoga 11 hybrid with Windows RT from online sales

July 17, 2013 Bartle Doo Leave a comment

Lenovo has discontinued sales of the Yoga 11 convertible with Windows RT on its website, which analysts said was a sign of PC makers moving away from their commitment to the struggling OS.

A page on Lenovo’s website stated the Yoga 11 is no longer being sold through its website, but said consumers “may still buy this product from a Lenovo retailer or reseller.”

The Yoga 11 is being sold by a few retailers such as TigerDirect, which is selling the device for $495. The device is not being sold by Best Buy, which is instead selling the Yoga 11S, a hybrid released earlier this year with Windows 8 and an Intel Core processor.

The Yoga 11 hybrid was one of the handful of computers running Microsoft’s Windows RT, which is designed for tablets. The Yoga 11’s dual functionality allowed it to be laptop, and also a tablet when the screen was folded up.
