The standardised physical appearance of new devices showcased at the IFA expo in Berlin this week belies the innovation lurking ‘under the hood’, writes ARTHUR GOLDSTUCK
The annual IFA expo in Berlin, drawing to a close this week, has always been Europe’s poor relation to the Consumer Electronics Show (CES) in Las Vegas. Where CES kicks off the year by playing host to the biggest array of product announcements at any technology event in the world, IFA tends to wrap up the year by bringing many of those same products to market.
The result is that many observers tend to yawn about the seen-it-all-before sense they get from IFA. However, there is a vast difference between what is seen and what is experienced. Many of the products on display may look like variations on what has gone before, but their capability or functionality has advanced dramatically.
In other cases, new technology is not of the dazzling, stand-out variety, but seamlessly and surreptitiously integrated with existing technology.
The best example is the smartphone, which offers little room for superficial innovation. The last big shift in format came 18 months ago, when Samsung introduced the curved screen to its Edge devices.
This year LG launched a “modular” phone with a slide-out bottom to allow the battery to be replaced by the likes of camera and sound modules. Lenovo followed up with a razor-thin Motorola Moto Z handset that allows sound, battery and projector “Mods” to be clamped to the rear.
However, the emphasis on the physical shape of the devices – and the recent absence of format innovation from a market leader like Apple – has meant that the innovation happening under the hood has largely gone unnoticed.
The best case in point from IFA 2016 was the new flagship smartphone from Sony, the Xperia XZ with 5.2” screen. Along with Huawei and Alcatel, Sony was one of the few manufacturers to use IFA for the launch of a major new smartphone.
Predictably, casual visitors to the Sony stand primarily saw a more sleek design and little else. Those who picked it up and played with it may well have got a sense of the fast and dazzling clarity provided by the phone’s camera. This is made possible by a 23MP rear camera and a dedicated shutter release button, which means going “from standby to capture in 0.6 seconds”, as Sony put it.
The electronics giant rightly claims that its new new models, including a 4.6” trimmed down version of the flagship called the Xperia X Compact, feature “one of the most advanced cameras in a smartphone”. Along with an already powerful image sensor, it includes two additional assisting sensors that add up to what Sony labels “triple image sensing technology”.
“This allows you to capture beautiful images in motion with true to life colours in virtually any conditions,” according to the company’s announcement of the new phone. “The technology is comprised of Sony’s original Exmor RS for mobile image sensor, which provides a powerful blend of high quality image and autofocus (AF) speed, combined with Predictive Hybrid AF to intelligently predict and track subjects in motion for blur-free results.
“Added to this is the Laser AF sensor with distance sensing technology, which captures beautiful blur-free photos in challenging low light conditions. And … true to life colours thanks to the RGBC-IR sensor with colour sensing technology which accurately adjusts the white balance based on the light source in the environment.”
That combination of technical and marketing speak does add up to one truth: this is probably the most complex camera system yet built into a smartphone. Manual settings for shutter speed and focus control add to the sense of this being a photographer’s phone.
But an even more remarkable innovation is built into the handset. Drawing on a legacy of image stabilisation developed for Sony’s Handycam camcorders under the SteadyShot brand, the technology has been enhanced on the XZ with “five-axis stabilisation”. This means it compensates for movement in any direction, allowing for smoother videos when filming while walking. Video can also be shot in 4K – currently the highest resolution that can be displayed on any but the most advanced displays in the world.
The front camera is also one of the best in the smartphone market, with a 13MP and 22mm wide angle lens. High light-sensitivity up to ISO 6400 allows for exceptional low-light performance.
For Sony – and many other smartphone manufacturers – the real problem with such innovation in the mechanics of a device is that it has to be experienced to be believed. The device has to prove itself in the field rather than in the showcase.
When word of mouth eventually kicks in and the world wakes up to inner beauty, such invisible innovation will come into its own.
Money talks and electronic gaming evolves
Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.
The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.
The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games.
It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.
MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.
“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”
New phenomena, often associated with the flavour of the moment, also emerge every year.
“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.
This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.
What is blockchain?
A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.
A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.
Each block stores:
– A number of valid records or transactions.
– Information referring to that block.
– A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.
Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.
As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.
How is blockchain so secure?
Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.
Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.
In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.
What else can blockchain be used for?
Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.
Use of blockchain in healthcare
Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.
Use of blockchain for documents
Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.
Other blockchain uses
This technology could also revolutionise the Internet of Things (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.
Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.
Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
