Windows 8.1 Enterprise Preview Reflects the Growing Trend of Working Remotely

Microsoft unleashed Windows 8.1 Enterprise Preview today. The early look at the enterprise version of Windows 8.1 follows the release of Windows 8.1 Preview at Microsoft’s BUILD conference last month, and includes a variety of tools that show Microsoft’s commitment to both BYOD and virtualization.

Aside from the slew of changes and enhancements in the regular Windows 8.1 Preview edition, Windows 8.1 Enterprise Preview also includes features uniquely designed for business customers. Windows 8.1 Enterprise Preview adds business-friendly elements like Direct Acess, and BranchCache. It also provides IT admins with the power to configure and lock down the Start screen on Windows 8 clients.

Microsoft also has tools in Windows 8.1 Enterprise Preview to help out with BYOD and virtualization: Windows To Go, and Virtual Desktop Infrastructure (VDI). Windows To Go lets the company put an entire managed Windows 8 desktop environment on a bootable USB thumb drive, and VDI gives the business the tools to enable users to use critical business software from virtually any Internet-connected device.

One of the hottest trends in business technology today is mobility and working remotely. The driving forces behind working remotely are the “bring your own device” (BYOD) trend and virtualization.

More and more companies are embracing BYOD and allowing (or requiring) employees to provide their own PCs and mobile devices. BYOD can be a cost-cutting measure for the company, because the employee is taking on some (or all) of the burden of purchasing the PC. BYOD enables users to be more productive and have higher job satisfaction because they get to use the hardware they prefer, and are more comfortable with.

BYOD also introduces some unique concerns, though, when it comes to enforcing policies and protecting company data. Regardless of its benefits, companies can’t just let employees connect rogue computers to the network, or store sensitive company data on a personal PC without any protection. The nice thing about Windows To Go is that it turns any Windows 7 or Windows 8 device into a managed Windows 8 PC without installing any additional software, or putting the personal applications or data of the employee at risk.

Another factor in working remotely is virtualization. Whether hosted locally or in the cloud,virtual servers allow the company to maximize the value from its investment in hardware, and adapt quickly to changing demand or business needs. From an endpoint perspective, virtual applications, or virtual desktop are more valuable. A virtual desktop infrastructure like in Windows 8.1 Enterprise simplifies deployment and management of software because the company only has to install and maintain it in one place. At the same time, it helps the users get more done even on older or weaker hardware because much of the processing overhead is handled on the server end.

Small and medium businesses have a lot to gain from both BYOD and virtualization. The features and capabilities of Windows 8.1 Enterprise Preview demonstrate Microsoft’s commitment to keeping SMB customers on the cutting edge.

Share Printer Access Windows 8

Increasingly diverse operating systems. Therefore, do not be surprised if within a network can terdisi from a variety of devices. Plus, gadgets and electronic devices now have the ability to pass network connectivity.

If the operating system both Windows or Linux fellow, it’s still easy. For use can be done without much trouble. Well if there are some who use the operating system Windows 8 and some of them have access to a printer via the Linux how dong? Easy! This tutorial.

Step 1:

Workgroup liken this step similar to when we want to share files across operating systems. We must do this step in Windows 8:

1. Create Same Workgroup. On the Start screen, click System Settings on the right side and click on System in the left side. Click the Change Settings.

2. In the System Properties window go to the Computer Name tab and see the workgroup name there. Compare with information workgroup name in Windows 8. If the same, you can jump straight to step 4. If different, follow the first 3 steps.

3. Click the Change button that is on the Computer Name tab. After that, in the Computer Name Changes window, click the Workgroup menu in the box if the Member in the column below, the contents of the same name with a Linux workgroup. Press OK to save the changes. When prompted, restart the PC in order to connect with the new workgroup.

Next, use the same naming workgroup with Linux.

Step 2:

To put the printer on Windows 8

Divide and put the printer is not difficult to access. On the Start screen, type in Device and Printers, click Settings and then click the icon. Figure 4. Right-click the printer you want to dibagipakaikan then select “Printer Properties”. In the Properties window, select the Sharing tab and place a check in front of the “Share this printer”. Figure 5. Click “OK” to save changes.

Step 3:

Configuring Linux For Linux printer can be accessed through, it is time configuration on Linux. We will be using Ubuntu as the most popular Linux ditro. Here’s how:

1. Click the menu System> Administration> Printing to open the printer management window.

2. In the Printer Configuration window, click the “New” button. Ubuntu will search for the printer on the network.

3. Once the search is complete, Ubuntu will display all the printers on the network are detected. If printermu not listed, click the “Windows Printer via SAMBA” on the left panel. IN the right side window, type the workgroup name created in step 1, and then click “Browse”.

4. Explore the SMB workgroup that appears in the browser, select the computer name, then click on the name of the printer that has dibagipakaikan then click “OK”.

5. You will be taken back to the previous window. Click the “Verify ..” to ensure the printer can be accessed by Ubuntu. If successful, you will get the message “Print Share Verified” like in the picture. If at this stage you have failed, try to go back to step 2 to ensure the printer configuration has been done correctly.

6. Click “OK” and “Forward”.

7. Now you will see a window with three options: Choose the printer from the database, providing PPD file, or do a search in the printer driver

Choose the first option and then check whether the driver for printermu already teredia. If printermu not listed there, select the second option. After that select the PPD file that you have and then click Open. PPD file is a file that contains information such as the printer’s Windows driver which can be downloaded from the Internet. If the second alternative in this step you have problems too, just select the third option to force Ubuntu to find drivers on the Internet.

8. Click the “Forward” button to continue.

9. Enter the printer name information, description and location of the printer in the field provided. Click Apply to continue.

10. Ubuntu will ask you to test your printer. Click “Yes” to try to print to the printer.

11. After all steps finished, you will see the printer connected to the PC Windows 8 appears in the printer list Ubuntu.

Acer Aspire V5-122 with AMD Temash

Jakarta-ultrabook exorbitant price makes it less attractive thin notebook. Despite having a number of advantages compared to notebooks in general, such as fast boot time and lightweight body, the average price is above USD 10 million to be a serious obstacle.

As an alternative, some computer vendors began marketing sense ultrabook notebook with a more affordable price. Call it VivoBook X202E Asus, Lenovo IdeaPad Yoga 11, Dell XPS 12, or Acer Aspire V5-122.

Yes, with many excellent features adopted from the ultrabook, notebook sold in the under $ 10 million. But in terms of performance is less than the true ultrabook. But the experience of computing an ultrabook can still be felt on the notebook.

In the past week, Tempo had tried Acer Aspire V5-122. Body is lightweight and thin making the Aspire V5 easily incorporated into the bag and convenient to carry anywhere. Interestingly, in the Aspire V5-122 grafted Temash low-power AMD processors.

DESIGN

Thin, lightweight, and stylish. That first impression when touched obtained Tempo Acer Aspire V5-122. Body wrapped in metallic silver color adds an elegant notebook with a 11.6-inch wide screen. While at the bottom, cover plastic dark black plated.

Every corner of the Aspire V5-122 made rounded. While the keyboard on the inside of the black chiclet design. Fairly wide spacing between the keys making it comfortable to use for fast typing.

Touch pad size is not too big, but it’s not a problem. Therefore, Aspire V5-122 is equipped with a touch screen that is able to respond to ten touch points. The touch screen was optimal when used with the Windows 8 operating system from Microsoft.

Like ultrabook, Aspire V5-122 also brought the concept of unibodi. That is, the types of Li-ion battery 3-cell it carries can not be removed. But you do not need to worry because Acer ensure the battery life is long enough.

Connectivity

Like most new output notebooks, Aspire V5-122 is equipped with the latest features for connectivity. One of which is USB 3.0 is capable of transferring and receiving data 10 times faster than USB 2.0. USB 3.0 port is located on the left side.

In addition to USB 3.0, Aspire V5-122 is equipped with a USB 2.0 port is on the right side. In addition there is a card reader slot. As for the wireless connectivity, Acer presents Wi-Fi 802.11 b / g / n and Bluetooth 4.0.

SCREEN

Screen Aspire V5-122 is able to produce high levels of brightness. Using glossy reflective technology, the Aspire V5-122 black color makes it look more dense and the resulting image sharpness deeper than the regular screen.

Only, with a relatively cheap price than the ultrabook, Acer just immerse the display with a standard resolution, 1,366 x 768 pixels only. That is, watch the video with 1080p high definition resolution was less than optimal on-screen Aspire V5-122’s.

Moreover, with the use of the Windows 8 operating system and the increasing number of applications that require content HD screen resolution, screen technology Aspire V5-122 feels a little left behind.

PERFORMANCE

Acer Aspire V5-122 is equipped with AMD processors Jaguar Temash APU A6-1450 quad-core processors with speeds up to 1 GHz of computing processes. As for the graphics processing embedded AMD Radeon HD 8280G which has a thermal design power (TDP), only 8 watts.

Jaguar AMD A6-1450 APU processor is the new output. This low-power processor platform is the successor of Zacate and Ontario, the first generation processor which is equipped with power-saving features with four cores.

Low power consumption that makes the battery life to be quite long. During the trial, Tempo get the battery can last up to 5 hours with normal use and use the Wi-Fi connectivity.

To support the performance of the processor, Acer relies DDR 3 RAM memory of 6 GB with a storage capacity of 500 GB hard-disk. Hard-disk usage is what makes the Aspire V5-122 can not be called as an ultrabook, but of course the use processors made by AMD.

CONCLUSION

Pegged at a relatively affordable price, about Rp 5.5 million, Acer Aspire V5-122 can be regarded as a substitute for the ultrabook much cheaper price. Elegant design and weighs only 1.3 pounds, this slim notebook comfortable to carry around.

As a colleague, Aspire V5-122 can be relied upon, especially he amplified output low-power processors AMD. In the market, the Aspire V5-122 directly compete with VivoBook S200E Asus, Lenovo IdeaPad Yoga 11, Lenovo ThinkPad Edge E130 and Sony Vaio SVE 1111.

Use Google Glass, Larry Page Feeling the Future

Jakarta – Founder and Chief Executive Officer of Google, Larry Page, said he likes to wear Google Glass although not as often as his fellow founders, Sergey Brin ie.

“It was like living in the future,” he said when presenting the company’s performance for the second quarter via teleconference. “It really makes me excited.” At a wedding in Croatia, Larry is seen wearing smart glasses.

“For some people, working on crazy projects are very challenging,” he continued. “Attempting to change the world with ten co-workers.”

Some projects that turned into a popular product used by many people in the world like Gmail, Chrome, and Android. “I see the results of our work on a number of projects and I feel satisfied.”

Several other projects are being worked on is the smart glasses Glass, Google Now, Project Loon, and a vehicle without a driver. “Misrepresentation if we assume the technology will be static,” he said.

Google Selects HE-AAC Multichannel From Fraunhofer IIS For Google Play Movies in Surround Sound

Google and Fraunhofer IIS deliver the first movies with a true 5.1 channel surround sound experience from Google Play. The immersive sound quality consumers have come to expect from TV, Blu-ray disc or DVD is now available with movies streamed or downloaded from Google Play directly to their Android devices running 4.1 or later. Google chose HE-AAC Multichannel as Android’s only surround sound codec due to its open-standard nature and excellent bit-rate efficiency.

When connected to a surround sound system and TV with an HDMI cable, Android users will be able to play high quality audio and video from their smartphones and tablets in surround. On the go, Android devices will play movies in great stereo quality and selected Nexus products will also include the Fraunhofer Cingo virtual surround rendering technology, which will play movies in realistic surround sound on earphones or tablet stereo speakers.

Android’s HE-AAC Multichannel implementation includes full support for loudness and downmix metadata commonly known from the broadcast TV world, as well as other features that allow the sound to be tailored for an optimum user experience in any listening mode and environment.

“Google Play movies in 5.1 HE-AAC Multichannel sound are the first realization of our vision of bringing true theatrical surround sound to mobile devices,” said Robert Bleidt, Division General Manager at Fraunhofer USA Digital Media Technologies. “The Google and Fraunhofer partnership creates a tremendous value for consumers by offering one format that delivers a high quality experience both in-home and while mobile. Consumers may experience surround sound over headphones while on their way home from work, and finish the movie in true, exciting surround in their living room,” he added.

HE-AAC Multichannel is part of the Fraunhofer FDK AAC codec library for Android since version 4.1 and a required feature of all Android-compatible devices. This software makes open-source Fraunhofer implementations of the MPEG audio codecs AAC, HE-AAC, HE-AACv2, and AAC-ELD available to the Android community.

HE-AAC is today’s most efficient high-quality surround and stereo audio codec deployed in over 5 billion devices and used in TV, radio, and streaming services worldwide. The codec is natively integrated into most operating systems, streaming platforms and consumer electronics devices. In addition to its unique coding efficiency, HE-AAC has the dynamic ability to change audio bit-rates seamlessly in order to adapt to changing network conditions as consumers stream content to a variety of devices. It can be used with any adaptive streaming technology including MPEG-DASH, Apple HLS, Adobe HDS and Microsoft Smooth Streaming.

This collaboration extends not only across their own company but across distributed external teams as well—improving workflows, streamlining marketing activities, and maximizing ROI. With the new single sign-on feature, customers can directly access Adobe Marketing Cloud solutions from within one unified interface, and the new social feed will deliver relevant internal content and insights shareable across Adobe Marketing Cloud solutions.

Hacking with a Hacker

What is it like to hack with one of the original hackers? It is certainly much different than what Appears to be the modern rendition of hacking. My experience was not getting really drunk with tons of junk food. It was not working on “beautiful” designs or “authentic” typography. It was not so much about sharing with the world as it was sharing with your peers. It had a very different feel to it than the “hacker culture” Promoted by some of the top technical Silicon Valley companies. It felt more “at home”, less dreamy, and more memorable.

I meet with Bill Gosper every so Often; I had the pleasure of giving him a tour of Facebook when I worked there. (He was so surprised that they had Coke in the glass bottles there, just like the old days.)

He is still very much a hacker, a thinker, a tinkerer, and a wonderer. Every time I meet up with him, he has a new puzzle for me, or someone around him, to solve, whether it’s really clever compass constructions, circle packing, block building, Game of Life automata solving, or even something more tangible like a Buttonhole homemade trap (which was affixed to my shirt for no less than two weeks!). He is also the bearer of interesting items, such as a belt buckle he gave me roomates depicts, in aluminum, a particular circle loose packing.
Gosper succeeding in tricking me with the Buttonhole Trap
When we meet up, all we do is hack. Along with him and one of his talented young students, we all work on something. Anything interesting, really. Last time we met up, we resurrected an old Lisp machine and did some software archeology. I brought over some of the manuals I own, like the great Chinual, and he brought over a dusty old 1U rackmount Alpha machine with OpenGenera installed. After passing a combination of Hurdles, such as that the keyboard was not interfacing with the computer Correctly, we finally got it to boot up. Now, I got to see with my own eyes, a time capsule containing a lot of Bill’s work from the 70s, 80s, and 90s, roomates could only be commanded and Examined through Zmacs dired and Symbolics Common Lisp. Our next goal was to get Symbolics Macsyma fired up on the old machine.

There was trouble with starting it up. License issues were one problem, finding and loading all of the files were compiled another. Running applications on a Lisp machine is very different than what we do today on modern machines, Windows or UNIX. There’s no. Exe file to click, or. App bundle to start up, or even a single. / File to execute. Usually it’s a collection of compiled “fast loading” or “fasl” files that get loaded side-by-side with the operating system. The application, in essence, Becomes a part of the OS.

In hacker tradition, we were Able to bypass the license issues by modifying the binary directly in Lisp. Fortunately, such as Lisp makes things easy disassembly. But how do we load the damn thing? Bill frustratingly muttered, “It’s been at least 20 years since I’ve done it. I just do not remember. “I, being an owner of MacIvory Symbolics Lisp machines, fortunately did remember how to load programs. “Bill, how about LOAD SYSTEM Macsyma?” He typed it into the native Lisp “Listener 2” window (we kept “Listener 1” for debugging), sometimes making a few typing mistakes, but finally succeeding, and then we saw the stream of files loading. We all Shouted in joy that progress was being made. I recall Bill was especially astounded at how fast everything was loading. This was on a fast Alpha machine with gobs of memory. It must have been much slower on the old 3600s they used back in the day.
The Lisp Machine Manual, or Chinual
It was all done after a few minutes, and Macsyma was loaded. To me, this was a sort of holy grail. I personally have Macsyma for Windows (which he uses in a VirtualBox machine on his 17 “MacBook), and I’ve definitely used Maxima. But Macsyma is something I’ve never seen. It was something that seems to have disappeared with history, something I have not been Able to find a copy of in the last decade.

Bill said, “let’s see if it works.” And he typed 1 +1; in, and sure enough, the result was 2. He saw I was bubbling with excitement and asked me if I’d like to try anything. “I’d love to,” and he handed the keyboard over to me and I typed in my canonical computer algebra test: integrate (sqrt (tan (x)), x);, roomates computes the indefinite integral
—- √ ∫ tanθ dθ
Out came the four-term typeset result of logarithms and arctangents, plus a fifth term I’d never seen before. “I’ve never seen any computer algebra system add that fifth term,” I said, “but it does not look incorrect.” The fifth term was a floored expression, Whose Increased value with the period of the function preceding it. “Let’s plot it,” Bill said. He plotted it using Macsyma’s menu interface, and it was what appeared to be an increasing, non-periodic function. I think we determined it was properly handled Because Macsyma branch cuts, with other systems have been known to be unorthodox about. It definitely had a pragmatic feel to it.

Now, Bill wanted to show us some interesting things; however all of Bill’s recent work Macsyma was on his laptop. How do we connect this ancient to a modern Macintosh hardware? We needed to get the machine onto the network, and networking with old machines is not my forte.

Fortunately, Stephen Jones, a friend of Bill’s and seemingly an expert at a rare combination of technical tasks, showed up. He Was able to do things that Neither Bill nor I could do on such an old machine. In only a few moments, he Was able to get Bill’s Mac talking to the Alpha, roomates shared a portion of its file system with Genera. “Will there be enough space on the Alpha for Macsyma my files?” Bill asked Stephen. “Of course, there’s ton’s of space.” We finally got Bill’s recent work transferred onto the machine.

We spent the rest of the night hacking on math. He Demonstrated to us what it was like to do a real mathematician’s work at the machine. He debuted some of his recent work. He went though a long chain of reasoning, showing us the line-after-line in Macsyma, number theoretic amazing to do things I’ve never seen before.

I did ask Bill why he does not publish more often. His previous publications have been landmarks: his algorithm for hypergeometric series and his summation algorithm for playing the Game of Life at light speed. He RESPONDED, “when there’s something interesting to publish, it’ll be published.” He seemed to have a sort of disdain for “salami science”, where scientific and mathematical papers present the thinnest possible “slice” or result possible.

Bill is certainly a man that thinks in a different way than most of us do. He is still hacking at mathematics, and still as impressive as before. I’m very fortunate to have met him, and I was absolutely delighted to see that even at 70 years old, his mind is still as sharp as can be, and it’s still being used to do interesting, Gosper-like mathematics.

And you would not believe it. We all were ready to head home at around 9 PM.

Sisco will buy software maker Sourcefire

Jakarta (ANTARA News) – Sisco System said it will buy software company Sourcefire Inc. for about $ 2.7 billion to improve the network security services.

Sisco will pay 76 dollars for each share of Sourcefire, 28.6 percent higher than the closing market price premium 59.08 dollars Monday, Reuters said in a report on Tuesday.

The networking equipment company said the deal would likely close the second quarter of 2013 and estimates that there will be a dilution thin on non-GAAP earnings in fiscal year 2014.

Sisco has been losing market share in network security last year, lower than the more innovative rivals such as Networks Inc., Check Point Software Technologies, and Palo Alto Networks Inc..

Sisco compete in Web applications, social media and video streaming that require security protection is more complex than traditional firewalls.

RBC Capital Markets analyst Robert Breza said the deal would eliminate a key competitor in the market for Check Point, Fortinet, and Palo Alto, but also strengthen the position of Sisco in the industry.

It would also create a major competitor in the network security industry, he said, adding that Sourcefire will bring the technology of real-time network awareness (RNA) and intrusion prevention system (IPS) to Sisco.
