Model railways have been around for a very long time, and enthusiasts will sometimes build huge layouts stretching across hundreds, even thousands of feet.

If you don’t have the space or the money, though, you might prefer 3D Train Studio, which enables you to build complex virtual model railways, with moving trains, working signals, even cockpit cameras to help you monitor what’s happening in your custom world.

Following the launch of Windows Phone 8 in late-2012, Microsoft's smartphone platform has significantly increased its market share, reaching more consumers in more regions across the globe. Its rise can be attributed, for the most part, to sales of low-end handsets, like the affordable Nokia Lumia 520 and Lumia 625, which are prevalent in emerging markets.

So, it should come as no surprise that emerging markets make up roughly half the list of the 20 largest Windows Phone markets, according to a new report from Windows 8 and Windows Phone advertising network AdDuplex. The leader of the pack, however, is US, with 11 percent of the user base.

Bitdefender has announced the release of its 2015 range, including Bitdefender Antivirus Plus 2015, Bitdefender Internet Security 2015, and the do-everything Bitdefender Total Security 2015.

The new builds add little to Bitdefender’s core security abilities, instead introducing what the company calls "OneClick Security", a strong focus on simplicity and ease of use.

Last year Lenovo extended its Yoga line to cover not just the company's rather clever folding hybrid Windows laptops, but Android tablets too. The designs weren't quite as ingenious as the IdeaPad Yoga, with its keyboard that flipped nearly 360 degrees to sit flat against the back of the display, but it still had a unique selling point (USP): A brilliant flip-out stand which could hold the tablet either tilted or upright.

It was a fabulous concept, but spoilt by a dated specification. The screen was a bog standard 1280 x 800 resolution effort, and the processor a lowly Mediatek quad-core CPU. Now, however, Lenovo has come back with the Yoga Tablet 10 HD+, enhancing the previous model with a full HD 1080p screen and a Snapdragon S400 SoC. Is this enough to make a great tablet from a great idea?

Symantec has unveiled the first public betas of its forthcoming Norton security products. Norton Security 2015 Beta and Norton Security with Backup 2015 Beta reveal the company’s attempt to harmonize its two main security products.

Both products sport a redesigned user interface based on the old Norton 360 product, plus sport a number of major new protection and performance improvements.

Where are our cities headed in the future? What can we expect from the long sought after "smart cities"? Can we really expect anything different?

If big data has anything to do with it, we certainly can. We've already seen tremendous strides over the last 20 years in creating more energy efficiency, cleaner air, better transportation and improved security, but it's only a small fraction of what we can expect to see in the future with big data.

The most popular computers nowadays, mobile devices such as smartphones and tablets, are full of compromises. Sure, they are sexy and fun to use, but hardly ideal for true work and creation. Hell, the "smart" in smartphone is starting to feel like a misnomer. A true desktop operating system coupled with a laptop, desktop or hybrid form factor will offer the most functionality and success.

Consumers have overlooked these mobile shortcomings as they have been mostly consuming content at home. However, the tides may be changing -- it feels like the consumer love-affair with mobile devices is starting to wane. Smart-watches may be the straw that breaks the camel's back. People are tired of retrofitting their desired computing to small screens. How about using an actual PC, rather than try to get PC functionality from a mobile device? Crazy concept, I know. Today, IDC announces that PC shipments are showing strong growth in the USA for Q2 2014, year-on-year.

Phones hit the headlines for lots of reasons -- the biggest, the most expensive, the shiniest, or just the newest. We live in times in which security and privacy are major concerns for people in all walks of life. The activities of the NSA, as revealed by Edward Snowden, served only to heighten paranoia -- the prospect of having one's phone calls and text messages intercepted is something that fills few people with joy. Enter Vysk communicastions' Vysk QS1 phone case which can be used with an iPhone 5 or 5s, and a Samsung Galaxy S5 or S4. The selling point here is that it's not just your phone that's protected, but also your privacy.

The privacy features come in mechanical and software forms. On the mechanical front there are "shutters" that can be used to obscure your phone's front and rear cameras, and there's also a jamming system for microphones. This is described by Vysk as "Lockdown Mode", but you can take things a step further. For $9.95 you can subscribe to "Private Call Mode". This introduces encryption to your texts and phone calls, with an onboard processor taking care of encryption on the fly and sent via the Vysk encrypted network. As Vysk puts it: "No one -- not even Vysk -- will know the identity of the caller or the recipient. No data is collected -- no phone numbers, call times or content - so there is no data to record. Because nothing is recorded, nothing is at risk."

We're growing accustomed to companies releasing transparency reports -- all seem to want to get in on the action and make themselves look good for the public. The latest report rolls out of US mobile carrier Verizon, and reveals the usual amount of troubling data requests. The most prominent being for customer location data.

Unlike some reports, the carrier provides actual numbers, as opposed to estimates. We see that the company received 72,342 subpoenas in the first half of 2014 (a number that is actually down compared to the second half of 2013), and 14,977 warrants. As for other requests, we only get estimates there -- for instance between zero and 999 national security requests were received.

Ransomware has proved to be a successful business model for cybercrooks and a recent study shows that IT professionals still see it as a major and growing area of concern.

In a study by security awareness training specialist KnowBe4 88 percent of the 300 professionals surveyed said they expected ransomware to grow over the rest of this year. Attacks are also shifting from desktops to mobile devices, leading to problems for BYOD users.

Kaspersky Labs has announced its updated product range for home users, including Kaspersky Anti-Virus 2015 ($59.95) and Kaspersky Internet Security 2015 (also $59.95, 3 PCs, 1 year: offer expires 25th August 2014).

Both products now include an extra layer of protection from Cryptolocker-type ransomware. Kaspersky’s System Watcher now looks out for suspect processes trying to modify user files, and immediately backs up the originals. If the package finds the process was malicious then not only will the malware be removed, but you’ll get your documents back, too (or any tampered with in this session, anyway – backups are deleted when the program closes down).

Earlier this week we covered the debate on whether Android users need malware protection. If further fuel for the argument was needed it comes in the form of Russian security firm Dr.Web's monitoring of Android threats.

Until recently embedded advertising modules have topped Dr.Web's malicious program rankings, but statistics for recent months indicate that an Android SMS bot Trojan has been spreading at an alarming rate.

Hitting the road means luggage, and luggage is a pain -- all that… stuff… to carry from place to place. Traveling light can help to make the journey less of a chore, but there are some things that simply have to be packed: no self-respecting technology fan would go on vacation without taking a raft of devices with them. But devices need power, and this means chargers are needed. iPhones, MP3 players, Android tablets, iPads, digital cameras, Chromebooks, and countless other devices all need power -- and that means a lot of chargers.

We just took a look at the Lumsing DCH-5U 5-Port USB Travel Wall Charger which enables you to leave the chargers at home and charge up to five devices simultaneously from a single power point. And we have one to give away!

Microsoft has been forced into a climb-down by returning 23 domains that were seized for allegedly being behind malware infecting Windows computers across the globe.

No-IP’s domains, which were seized on June 30 after a court order allowed Microsoft to do so, were implicated in an investigation into various domains being used by cybercriminals to operate the Bladabindi and Jenxcus malware families.

A few weeks ago I took a look at Lumsing's harmonica battery pack. Now from the same stables comes the lengthily titled DCH-5U 5-Port USB Travel Wall Charger. This is a slightly different twist on the idea of providing power to travellers' devices -- this is a wall charger rather than a portable battery pack. If you're going on vacation, taking a trip, or even just hitting the office, there are your devices to consider. Your phone, tablet, MP3 player, and other bits and pieces all need power, all need their own charger.

Except they don’t. Leave all of your chargers at home, and just take a selection of USB cables -- this 5-port hub allows for up to five USB devices (obviously) to be charged from a single wall power point. The 31W/6.2A unit has two 5V 1A ports for phones, and three 5V 2A ports for tablets and devices with higher power demands. Oddly, the ports are labelled, left to right, iPad, iPad, Samsung Tab, iPhone, and Android. It would have made more sense to simply indicate which of the five were the high-powered ports, but this is a minor niggle in the grand scheme of things.
