5 steps to take command of mobile

The hottest topic in enterprise IT is secure mobility — in other words, allowing secure access to the enterprise infrastructure from any device, anywhere and at any time. Successful mobility solutions require deliberate implementation, disciplined security plans, careful consideration of who needs to be mobile-enabled, and the implementation of a sophisticated, secure, mobile enterprise infrastructure.

Here are five steps to take command of your organization’s mobility initiative.

1. Create a policy. Before committing enterprise resources to secure mobility, you must determine which job functions truly need to be mobile and why. Letting everyone go mobile without restriction is unrealistic, so define what job functions require mobility and set up user profiles accordingly. For instance, many workers will only need secure mobile access to e-mail rather than an entire suite of applications.

2. Make security dynamic. Borderless anytime/anywhere mobility presents genuine security challenges, and obviously, the consequences of a breach — especially of government networks — are extremely serious. A security plan must be dynamic enough to change as hackers’ tactics change and incorporate the latest multilayered credentialing technologies. Moreover, any security strategy must strive to eliminate vulnerabilities while presenting a fast-response action plan for dealing with a breach or failure. The plan should be at least as strong as the security plan at the physical office, with the addition of the capability to automatically lock out mobile devices that exceed security allowances set up in the user profile. For instance, device lockout can occur when someone uses unauthorized software or applications. User profiles can enforce corporatewide policies or be individualized.

Android: Haya sasa Kwa wale Wapenda Urahisi hasa wa simu kazi kwenu

Because it’s open source, Android is the perfect operating system for building low-cost smartphones for emerging markets. — Picture courtesy of ©Android

Demand from the Asia Pacific region, the Middle East and Latin America is fuelling the growth of the low-cost smartphone market as well as manufacturers’ use of the Android operating system.
Low-cost smartphones look to be a key driver of spreading the technology and of bringing mobile connectivity to users worldwide. According to the latest figures from NPD Group released on Oct 22, shipments of sub-US$150 (RM459) handsets has been doubling year-on-year since 2010 and the trend looks set to continue until 2016, when shipments are expected to hit 311 million. Demand is being driven by the Asia Pacific region (60 per cent of shipments) but growth is also occurring in the Middle East and Africa, Latin America and Eastern Europe.
“Most mobile phone subscribers around the world can’t afford to spend more than US$200 for a smartphone, on top of their service plans,” noted Shawn Lee, Research Director at NPD DisplaySearch.
“Low-cost smartphone manufacturers create these new products quickly without much investment, which has allowed them to extend their telecom subscriber base to emerging regions.”
And as this growth in low-cost handset continues, so will the use of Google’s Android as their operating system.
As it is open source, it is the ideal operating system for entry-level phones.
Sub-$200 Android phones currently account for 2 per cent of total worldwide smartphone shipments.
However, by 2016 low-cost Android phones alone could account for up to 29 per cent of global smartphone shipments, or the equivalent of the entire worldwide smartphone market in 2010. — Reuters

Kwa watumiaji wa laptop chukua hizo tips: 5 Ways to Supercharge Your Laptop For Under $100

Whether you have a 4-year-old notebook or a shiny new system you bought yesterday, you can dramatically improve your PC’s performance and productivity value for less than the cost of a nice dinner out. For less than $100, you can purchase your choice of significant hardware upgrades that will allow you to get more done in less time and put off buying a new system for several more years.

1. Upgrade to SSD ($80 to $100)

There is no single upgrade that will improve your digital life more than going from a standard hard drive to an Solid State Drive (SSD). If you’re still using a 7,200 rpm or (gasp) 5,400 rpm drive, you’re wasting precious seconds of your life every time you boot, open a file or a launch a program. Instead of twiddling your thumbs while the old-fashioned turnable-like head spins inside your hard drive, you can be up and running in your favorite programs, including heavy applications like Photoshop, in just a few seconds.

e

When we took a 5-year-old Dell Latitude D630 running Windows Vista on a 2.4-GHz Core 2 Duo CPU and tested it with both its original 7,200-rpm hard drive and a speedy Kingston HyperX SH100S3 SSD, it felt like we were using two different computers. On PCMark Vantage, a synthetic benchmark that measures system performance, upgrading to SSD raised the D630′s overall score from 3,210 to 4,693 and its HDD score from 2,666 to 16,715.
In real-world tests, the Latitude D630′s Vista boot time decreased by around 20 percent, falling from an average start time of 37.3 seconds to 31 seconds. When we tested the launch times for five popular applications (Photoshop CS5.1 opening to a 400MB TIF, Adobe Reader 10 opening to a 500 page PDF, Excel 2007 opening to a 20,000 row worksheet, Mozilla Firefox 14 and Word 2007 opening to a blank document), each program opened about three times faster after the SSD upgrade.

Application	Hard Drive Open Time (sec)	SSD Open Time (sec)
Adobe Reader 10 (opening to PDF)	6.1	2.3
Photoshop CS 5.1 (opening to TIF)	28.6	9.6
Excel 2007 (opening to large worksheet)	8.4	2.8
Firefox 14	5.5	1.4
Word 2010	2.1	0.9

To see how much benefit an SSD provides on a new notebook, we opened some of the same applications and timed them on a 3rd Generation Intel Core i7 notebook, both with a 7,200 rpm 750GB hard drive and the same Kingston HyperX SH100S3 SSD. Even with a much newer, faster processor, launch times were 2 to 4 times faster after the upgrade.
Today, you can get a 120 or 128GB SSD for well under $100. A quick glance at popular retailers such as NewEgg, Tiger Direct and Amazon shows some budget-oriented SSDs like the OCZ Agility 3 selling for under $90 while the Samsung 830 Series, the winner of our Fall SSD roundup, can often be found on sale for $99 or less. If you require more capacity, you can find a 256GB drive for as little as $150.

2. Add more RAM ($20 to $40)

The more RAM your notebook has, the less time it must spend writing to the Windows paging file on your hard drive (or SSD) to help make up for a lack of a physical memory. Since physical memory is infinitely faster than even the fastest SSD, you want to avoid your system needing to use that paging file whenever possible. Even better, if you have some memory to spare, you can create a RAM disk which will load your favorite programs much faster than even a speedy SSD.
Most of today’s notebooks come with 4GB of RAM and moving from 4GB (or less) up to 8GB can provide significant performance gains. If you have DDR3 memory, the standard type since 2009, an 8GB kits (2 x 4GB DIMMs) will cost you $40 or less.
Since most notebooks have just two slots for RAM and come with both filled, you’ll probably have to remove your existing RAM. However, if you do have a free slot, the cost of a 4GB DIMM is around $20. To find out what kind of memory your notebook takes, either consult your owner’s manual or visit an online RAM configurator like the one on Crucial Memory’s home page. Removing and replacing RAM on most notebooks is as simple as unscrewing a door on the bottom of the system, popping out the old chips and popping the new ones in.
 To show the benefit of increased memory, we ran PCMark 07, a leading synthetic benchmark, on an Intel 3rd Generation Core i7 CPU, with both 4GB and 8GB of RAM installed. With 8GB installed, the benchmark returned a score of 3,398, about 9 percent higher than the mark or 3,121 it provided with 4GB on board.

We also tried configuring 4 out of the 8GB as a RAM disk, using DataRAM’s free RAMDisk software. With some of our favorite programs installed on the RAM disk, we were able to cut open times in half from what they were on a 7,200 rpm hard drive and reduce them even further when we paired the RAM Disk with an SSD.

Application	HDD Only (sec)	HDD / RAM Disk (sec)	SSD Only (sec)	SSD w/ RAM Disk (sec)
Adobe Reader 10 (opening to large PDF)	7	3.6	3.5	3.1
Excel 2010 (opening to large spreadsheet)	10	4.1	3.7	1.9
Photoshop CS 5.1 (opening to 400MB TIF)	22.1	9.7	5.5	4.8
Word 2010	3.1	1.6	0.8	0.4

3. Get an external monitor ($80 to $100)

You can never be too rich, too thin or have too many pixels on your desktop. If you’re just relying on your laptop’s single screen, you’re slowing yourself down, because you can’t fit enough windows on the screen at once.
Just imagine this situation. You’re working on a PowerPoint presentation in one window while using data from an Excel sheet that’s in another window, looking up some facts on the Web in your browser and keeping track of your email in a fourth window. Every time you switch windows — either by hitting ALT tab or by navigating to the task bar — you’re wasting a good 2 seconds and taxing your short-term human memory because you have to remember the contents of a window that’s now covered over.
With an external monitor attached, you can add a whole second desktop, which can either show one full screen window or two half windows that are docked next to each other. These days, you can get an 18.5- or 20-inch monitor today for $80 to $100. A quick survey of online retail sites shows several 20-inch, 1600 x 900 monitors priced at just under $100 and 18.5-inchers with 1366 x 768 resolutions starting as low as $80. If you’re willing to splurge, you can find a 1080p, 22- or 23-inch monitor for well under $150.
If you want a monitor you can take with you on the road, you can find a portable, USB-powered monitor such as the 15.6-inch AOC e1649Fwu for under $100. However, we prefer the lighter, more portable, but more expensive $174 Lenovo ThinkVision LT1421.

4. Step up to 802.11n Wi-Fi ($10 to $20)

If your notebook is more than three years old, it may have an older 802.11g wireless radio, which is significantly slower and less reliable than the current 802.11n standard. With 802.11n, you move from a theoretical maximum of just 54 Mbps to 150 or 300 Mbps, depending on your router and radio.
While the stepping up from 54 to 150 Mbps probably won’t improve Web page loads, it will enable you to transfer files a lot faster within your home or office network. That means better streaming from your media center, better backups to connected storage drives and faster copying of photos to and from your family members’ PCs. If you have an extremely fast fiber optic broadband plan such as Verizion’s 300 Mbps FIOS Quantum, you’ll see a boost in video streaming and file downloads. No matter what you’re doing, you’ll also see an increase in range, making it easier to get a strong signal when you’re further away from the router.

The good news is that you can get an 802.11n Wi-Fi dongle that plugs into one of your USB ports for under $20. For just $10, Rosewill’s $9.99 RNX-MiniN1 802.11n dongle offers speeds up to 150 Mbps and is so tiny that it looks like one of those nano receivers that come with some wireless mice. The $16.99 Rosewill RNX-MiniN2 sticks out a little bit more, but offers up to 300 Mbps and is still short enough to stay attached to your notebook when you stick it in your bag. If you don’t already have an 802.11n router at home, you can purchase one for as little as $25 for a 150 Mbps unit or under $50 for a 300 Mbps model.
To see just how much additional throughput you get from upgrading to 802.11n, we used the Netperf benchmark to test an old Dell Latitude D630 laptop with its native 802.11g Wi-Fi, and then with the Rosewill RNX-MiniN1 and the faster Rosewill RNX-MiniN2. Though our results on the small file transfer were well below what’s theoretically possible even with 802.11g, there was a clear difference in performance between the three adapters.

5. Get an external battery ($70)

If your notebook provides over 12 hours of endurance, perhaps you can live without more battery life. Whether you’re sitting on an airplane or lying on the couch, you don’t want to have to worry about finding and tethering yourself to an outlet.
Unfortunately, in LAPTOP’s tests, the average mainstream notebook provides just five and a half hours of endurance at 40 percent brightness. Even worse, more and more new systems come with sealed batteries you can’t replace, so forget about buying an extended unit or carrying a spare.
However, for around $70, you can purchase an external notebook battery such as the $69 Veho Pebble Pro. I’ve been using the Pebble Pro for a couple of months now and found that the 13,200 mAH battery provides another several hours of charge to my notebook while, at just 14 ounces, barely adding any weight to my bag. Because the battery comes with 10 different connectors, it works with nearly any brand of PC notebook on the market and is able to charge a phone or tablet at the same time.

10 Tips to Make your Phone's Battery Last Longer..

 

Even hi-tech smartphones can last for days - as long as you follow a few basic procedures to keep the battery at full.

As smartphones have become more capable -  for playing gaming, watching movies and shooting video -  battery performance has worsened and now most modern smartphones won’t last a full a day before you need to reach for a charger.

Phone manufacturers are working hard to improve battery performance - Motorola in particular with their RAZR i and RAZR MAXX - but if you buy most other smartphones, be ready to charge every evening.
Here are some tips to help conserve your mobile phones battery life:

                  [Related: First pics of new iPad Mini appear on Twitter]

Power-saving mode
Modern Android and Windows Phone smartphones include power or battery saving modes typically located in the Settings menu. It is activated once the battery reaches a certain level, forcing battery intensive features - including push email, screen brightness and Facebook updates - to switch off. Unfortunately Apple doesn’t include any such power or battery saving features on its smartphones, although free apps like Battery Life Pro help monitor performance and shut down applications.

                       [Related: Get the best prices on mobiles here]

Screen brightness
The biggest drain on a mobile phone battery is the screen and unfortunately the bigger and brighter the screen, the more battery life it uses. Save battery power by selecting ‘Automatic brightness’ and the screen will adjust the brightness automatically depending on the lighting conditions.

Alternatively, if the battery indicator is reaching precarious levels turn the brightness down as low as is comfortable to conserve as much power as possible.

Make sure auto lock is activated, so when your phone isn’t being used the screen shuts down saving power. 

If you’ve got a phone with an AMOLED screen (such as the Samsung Galaxy S3 or S2) using a dark wallpaper may also help save battery.

Don’t vibrate
In a working environment where loud ringtones are frowned upon, instead of popping your mobile phone in vibrate mode, which uses your battery, use silent mode instead.

                        [Related: Which Android is best for you?]

Stop email sync
Your phone probably checks for emails every few minutes or if you’ve got a smartphone that supports push email, constantly. Every time your phone syncs or an email is ‘pushed’ though, it uses battery power. To change the rate of email syncing or to switch it off, go into the Settings menu of your smartphone and increase the interval your phone checks email, it varies from phone to phone, but we would suggest setting it to check every half hour, or to switch off sync completely. You can therefore manually check your email as and when you choose and save a sizable chunk of battery life in the process.

Reduce social networking updates
Getting Facebook and Twitter notifications delivered to your phone automatically (like push email) uses your battery, so turn notifications off. Most phones allow you to switch off all syncing with a simple toggle.

Turn connections off
WiFi, GPS and Bluetooth are found on most modern phones. Forget to turn your WiFi off when you leave the house and it will continually look for a WiFi connection, using the battery. So make sure you turn any connections off when you are not using them.

Shut down apps
Even if you are not using an application it may still be running in the background using the battery, so close any apps you aren’t using.  Do this on an iPhone by double tapping the menu button, pressing the program icon and click the minus button.

On older Android smartphones, you may need a task manager to do this, however newer handsets running Android 4.0+ allow you to pull up a task manager by simply long pressing the home button. You can then thumb through your open apps and swipe them off screen to close them. You can even see what apps use the most battery in the settings of your Android smartphone.


Don’t download pictures
Downloading pictures when browsing or using email is something most of us do without thinking, but every time you download a photo it uses both data and power. So if you can live without pictures, turn them off in the internet browser’s settings menu.

Flash off
When taking photographs using your smartphone, be conservative with your flash use. In digital cameras the flash is a huge battery drain and the same applies to phones, so instead of leaving it in automatic mode, turn the flash off when taking photographs, only turning it on when necessary.

Night time = downtime
Night time is the time most people charge their smartphones, but if you don’t have a charger to hand make sure you turn your phone off at night.

Aeroplane mode
Smartphones are always trying to connect to a network, be it a cellular network, a wireless network or a data network. The harder they try and connect, the more battery they use. A
great way to save your battery is to switch on aeroplane mode when reception is poor or you’re underground. This stops your phone searching for signal when there’s none to be found and makes the best use of whatever battery you have left.

Accessorise
If you’ve followed the above tips and your phone battery still doesn’t last very long, it’s time to consider a charging accessory. The Mophie JuicePack Air (£40) fits over your smartphone, doubling the battery life, alternatively if you don’t fancy changing the look of your phone consider a portable battery charger like Proporta TurboCharger 7000 (£54).

Google says: Maps not waiting in wings for iPhone 5

Google Inc has made no move to provide Google Maps for the iPhone 5 after Apple Inc dropped the application in favor of a home-grown but controversial alternative, Google's Executive Chairman Eric Schmidt said.
Apple launched its own mapping service earlier this month when it began providing the highly anticipated update to its mobile software platform iOS 6 and started selling the iPhone 5.
But users have complained that Apple's new map service, based on Dutch navigation equipment and digital map maker TomTom NV's data, contains glaring geographical errors and lacks features that made Google Maps so popular.
"We think it would have been better if they had kept ours. But what do I know?" Schmidt told a small group of reporters in Tokyo. "What were we going to do, force them not to change their mind? It's their call."
Schmidt said Google and Apple were in constant communication "at all kinds of levels." But he said any decision on whether Google Maps would be accepted as an application in the Apple App Store would have to be made by Apple.
"We have not done anything yet," he said.
Google and Apple were close partners with the original iPhone in 2007 and its inclusion of YouTube and Google Maps. But the ties between the two have been strained by the rise of Google's Android mobile operating system, now the world's leading platform for smartphones.
Schmidt said he hoped Google would remain Apple's search partner on the iPhone but said that question was up to Apple.
"I'm not doing any predictions. We want them to be our partner. We welcome that. I'm not going to speculate at all what they're going to do. They can answer that question as they see fit," he said.
Google provides Android free of charge and allows developers to add applications on an open basis, betting that by cultivating a bigger pool of users - now at over 500 million globally - it can make more money by providing search functions and selling advertising.
"Apple is the exception, and the Android system is the common model, which is why our market share is so much higher," Schmidt said, adding that success was often ignored by the media, which he said was "obsessed with Apple's marketing events and Apple's branding."
"That's great for Apple but the numbers are on our side," he said.
At one point, Schmidt, who was in Japan to announce the launch of Google's Nexus tablet here, used the device to show off a new function of Google Maps.
The feature allows users to shift their view of an area by moving the device in the air without touching the screen, similar to the effect of looking around.
"Take that Apple," he said, adding quickly, "That was a joke by the way."
