While Blockchain technology is worth investigating, CIOs should not be fooled into thinking it is the remedy for all the potential use cases currently under discussion, advises Forrester principal analyst, MARTHA BENNETT.
Stories about digital currencies in general, and Bitcoin in particular, are still filling news feeds. However the industry is now more focused on the underlying technology of the blockchain and the concept of the shared ledger.
This is most clearly evidenced by the raft of startups which have been attracting headlines and investment dollars. A number of established companies are also investing in in-depth research and even proof of concept projects.
Despite what the headlines suggest, all blockchain projects are in the early exploratory phases. It’s not something you can buy and deploy and, what’s easily forgotten in all the euphoria, is that very little has actually been proven yet.
This does not discount the future potential of blockchain technologies. There are many startups with interesting technology approaches and compelling use cases, and some of the world’s best-known technology and consulting firms are working on blockchain projects.
However, it is clear that CIOs should critically assess what their needs are and get a much fuller understanding of their options before jumping on board the blockchain bandwagon.
Many a CIO has asked just how seriously they should be taking blockchain technologies, and when this happens the recommendation is to apply some basic but important reality checks.
At the outset it’s important to define what your understanding is. Like ‘cloud’ or ‘big data’, ‘blockchain’ means different things to different people. It’s important to ascertain what a particular person or company means by the term.
Find out which issues the blockchain technology addresses that aren’t possible to address in any other way and, if it does address these, has this been proven? Similarly, if cost savings are being put forward for using blockchain, has this been proven?
There are many interesting projects in the labs at startups, banks, and consulting firms. Many of these are even functioning prototypes, but it’s already conceded that they won’t scale at enterprise level.
In addition to this, Blockchain is a regulatory quagmire and many development companies fall short by not engaging with regulators before they offer the solution to clients.
Looking past the Bitcoin blockchain and its limitations, one can remain fairly upbeat about some of the alternatives. Ethereum, is of particular interest. With its Turing-complete programming language, it is more suited to complex requirements. But it isn’t the perfect solution either for the types of use cases currently put forward for blockchain solutions in an environment involving trusted parties. Hence the emergence of initiatives such as the Linux Foundation’s Hyperledger Project.
In short, companies should apply a five- to ten-year timeframe and keep asking ‘why?’
Blockchain technology today belongs in the research or innovation lab. For each project, there must be a detailed explanation of why and how blockchain is more efficient, secure, and lower cost than any of the available alternatives, as well as being legally acceptable.
Android Go puts reliable smartphones in budget pockets
Nokia, Vodacom and Huawei have all launched entry-level smartphones running the Android Go edition, and all deliver a smooth experience, writes BRYAN TURNER.
Three new and notable Android Go smartphones have recently hit the market, namely the Nokia 1, the Vodafone Smart Kicka 4 and the Huawei Y3 (2018). These phones run one of the most basic versions of Android while still delivering a fairly smooth user experience.
Historically, consumers purchasing smartphones in the budget bracket would have a hit-and-miss experience with processing speed, smoothness of user interface, and app stability. The Google-supported Android Go edition operating system optimises the user experience by stripping out non-important visual effects to speed up the phone. Thish allows for more memory to be used by apps.
Google also ensures that all smartphones running Android Go will receive feature and security updates as they are released by Google. This is a major selling point for these smartphones, as users of this smartphone will always be running the latest software, with virtually no manufacturer bloatware.
Vodafone Smart Kicka 4
At the lowest entry-level, the Vodafone Smart Kicka 4 performs well as a communicator for emails and WhatsApp messages. The 4” screen represents a step up for entry-level Android phones, which were previously standardised at 3.5”.
The display is bright and very responsive, while the limited screen real estate leaves the navigation keys off the screen as touch buttons. It uses 3G connectivity, which might seem like an outdated technology, but is good enough to stream SD videos and music. Vodacom has also thrown in some data gifts if the smartphone is activated before the end of September 2018.
Its camera functionalities might be a slight let down for the aspirant Instagrammer, with a 2MP rear flash camera and a 0.3MP selfie snapper. Speed wise, the keyboard pops up quickly, which is a huge improvement from the Smart Kicka 3. However, this phone will not play well with graphics-intensive games.
Next up is the Nokia 1, which adds a much better 5MP camera, improved battery life and a bigger 4.5” screen. It supports LTE, which allows this smartphone to download and upload at the speed of flagships. It also sports the Nokia brand name, which many consumers trust.
Although the front camera is 2MP, the quality is extremely grainy, even with good lighting. This disqualifies this smartphone for the social media selfie snapper, but the 5MP rear camera will work for the landscape and portrait photographer.
The screen also redeems this smartphone, providing a display which represents colours truly and has great viewing angles. Xpress-on back covers allows the use of interchangeable, multi-coloured back covers, which has proven to be a successful sales point for mid-range smartphones in the past.
Huawei Y3 (2018)
The most capable of the Android Go edition competitors, the Huawei Y3 (2018) packs an even bigger screen at 5”, as well as an improved 8MP rear camera and HD video recording. The screen is the brightest and most vibrant of the three smartphones, but seems to be calibrated to show colours a little more saturated than they actually are.
Nevertheless, the camera outperforms the other smartphones with good colour replication and great selfie capabilities via the 2MP front camera – far superior to the Nokia 1 despite the same spec. LTE also comes standard with this smartphone and Vodacom throws in 4G/LTE data goodies until the end of September 2018. The battery, however, is not removable and may only be replaced by a warranty technician.
Comparing the 3
All three smartphones have removable back covers, which provide access to the battery, SIM card and SD card slots. The smartphones have Micro USB ports on the bottom with headphone jacks on the top. The built-in speakers all performed well, with the Y3 (2018) housing an exceptionally loud built-in speaker.
Although all at different price points, all three phones remain similar in performance and speed. The differentiators are apparent in the components, like camera quality and screen quality. It would be fair to rank the quality of the camera and battery life by respective market prices. The Vodafone Smart Kicka 4 performed well, for its R399 retail price. The Nokia 1, on the other hand, lags quite a bit in features when compared to the Huawei Y3 (2018), bwith oth retailing at R999.
SA gets digital archive
As the world entered the centenary of Nelson Mandela’s birth on Mandela Day, 18 July 2018, South Africa celebrated the launch of a digital living archive.
The southafrica.co.za site carries content about the country’s collective heritage in South Africa’s eleven official languages.
Designed as a nation building, educational and brand promotion web based tool, the free-to-view platform features award-winning photographic and written content by leading South African photographers, authors, academics and photojournalists.
The emphasis is on quality, credible, factual content that celebrates a collective heritage in terms of the following: Cultural Heritage; Natural Heritage; Education; History; Agriculture; Industry; Mining; and Travel.
At the same time as reflecting on the nation’s history, southafrica.co.za celebrates South Africa’s natural, cultural and economic assets so that the youth can learn about their nation in their home language.
Southafrica.co.za Founder and CEO Hans Gerrizen conceptualised southafrica.co.za as a means for youth and communities from outlying areas to benefit from the digital age in terms of the web tool’s empowering educational component.
“We can only stand to deepen our collective experience of democracy and become a more forward planning nation if we know facts about our nation’s past and present in everyone’s home language,” he says.
Southafrica.co.za, with sister company Siyabona Africa, is the organiser and sponsor of the Mandela: 100 Moments photographic exhibition that runs until 30 September at Cape Town’s V&A Waterfront-based Nelson Mandela Gateway to Robben Island. The 3-month exhibition, which runs daily from 08h00 until 15h00, is showcasing one hundred iconic Nelson Mandela images taken by veteran South African photojournalist and self-taught lensman Peter Magubane.
