Mon, 26 Oct 2015 12:30:48 +0000 en-US hourly 1 https://wordpress.org/?v=4.5.32 Top 8 Samsung Ignite start-ups announced http://blog.tech4africa.com/top-8-samsung-ignite-start-ups-announced/ Thu, 13 Oct 2011 10:52:11 +0000 http://t4a.feedmybeta.com?p=1294 Continue reading ]]> Eight local technology start-ups have been offered a unique opportunity to pitch their business ideas to delegates, potential investors and media at this year’s Tech4Africa conference, taking place at The Forum in Bryanston, Johannesburg on 27 and 28 October.

This platform has been created by virtue of Samsung Ignite, an initiative that aims to showcase and foster local technology development, and which has been made possible by Samsung Apps store, in association with Tech4Africa. In the words of Gareth Knight, our founder and MD, “this platform allows local technology innovators to showcase their ideas to a broad audience, potential investors and technology entrepreneurs who have walked this path before”.

Tech4Africa’s primary aim is to promote and inspire local mobile and web innovators, entrepreneurs and developers by inviting global leaders in the sector to share their knowledge and insight with an audience from across the continent. The Samsung Ignite programme is an integral part of the overall conference’s vision that it is hoped will provide the spark that the eight start-ups need to take the next step in their development.

The 8 selected startups include:

10Layer: the most feature-complete, competent and customisable open source content management system for serious publishers and media houses.

FeedbackRocket.com: which offers an innovative online solution to obtain useful, insightful and honest feedback.

iSign.pro: that allows users to get legally-binding contracts signed in minutes – legally, cheaper, greener and stored forever, with automatic reminders before renewal/expiry.

Lessfuss: is an affordable South African personal assistant service that helps you save time and get things done for as little as R30/task.

Mobiflock: is a product range that consists of a parental control service, a personal smartphone tracker, and a corporate smartphone manager.

Plot my Ride: is a social networking service for the cycling community that offers an easy and real-time means of capturing, displaying, saving and sharing a cyclist’s riding activity.

Real Time Wine: captures the supermarket wine-buying audience and empowers them to discover, review, engage with and buy wine using smartphone apps, game mechanics & barcode scanning.

SnapBill: is an automated billing system that allows users to easily sell their services online.

“We are very passionate about the African market and encouraged by the innovations emerging from the continent, so it’s a natural fit for us to partner with Tech4Africa to present this stage for innovators to showcase their products,” says Brett Loubser, B2C Apps Development Lead at Samsung. “We intend using this partnership to help create a wider network of local developers, reward African innovation in the mobile tech and app space and promote the Samsung Apps Store as an alternative channel for smartphone developers”. Loubser added: “A key outcome of our participation as the Ignite partner is to engage South African developers and therefore we have made available a number of discounted tickets to facilitate their involvement at this year’s conference.”

The Samsung Ignite participants will each be afforded five minutes to showcase their products in the main auditorium at the end of the first day of the conference. A panel of judges has been gathered to adjudicate and the winning startup will be announced on the second day of the event, and be given the opportunity to present their start-up to the entire Tech4Africa audience. The winner will also receive the latest Samsung mobile devices and valuable exposure and profiling through the Tech4Africa website.

The event provides South Africans with a rare opportunity to learn firsthand from technology evangelists about the role that the web plays in African business and development.

The two-day conference runs from 27 to 28 October 2011 at The Forum in Bryanston, Johannesburg and will bring international experience and perspectives to the African continent, while at the same time showcasing what Africans are doing with mobile, web, digital media and other emerging technologies.

Registration for the event is open and early bird tickets are available until 15th of June. To register or for further information, visit Tech4Africa or contact us.

“2010 saw the launch of Tech4Africa and we were met with overwhelming support from both the tech and business communities and our foundation partners, First National Bank and Internet Solutions,” says Gareth Knight, MD of Tech4Africa. “This year we’re delivering the same high standard of content and looking forward to bringing technologists together to look at what’s current now, with an emphasis on social media and how it’s relevant to digital marketing, mobile convergence, the growing cloud and the applications of BigData. We’re also focusing on great African technologists that really are leading the way.”

Keynote speakers include Josh Spear, one of the youngest and most respected digital marketing strategists in the world, and Herman Chinery-Hesse, commonly known as ‘The Bill Gates of Africa’.

Spear is a trend spotter, blogger and brand strategist, sought out for his fresh perspective and no-holds-barred style of consulting on everything from design and gadgets to authenticity and word-of-mouth. His recent focus has been the power of the blogosphere, technology, and the impact of digital media on the world. In addition to his internationally recognised trend-spotting blog, he is a founding partner of Undercurrent, a digital think-tank focused on exploring new ways to reach young people without interrupting them. With Africa rapidly leapfrogging the web and PC experience with a mobile one, the insights into how people and brands interact digitally is crucial, and indeed sets the stage for the foreseeable future. Spear has appeared in publications including Time Magazine, the New York Times and the Chicago Tribune and has presented for such diverse clients as McDonald’s, NBC, Pepsi, Virgin, The American Advertising Federation and The Google Zeitgeist conference.

Chinery-Hesse is a renowned Ghanaian technology entrepreneur who co-founded the million-dollar software company SOFTtribe, and then went on to launch BSL, which provides the infrastructure for entrepreneurs across Africa to sell products and receive payment through their cell phones. Chinery-Hesse is passionate about the contribution that technology can make in unlocking prosperity and wealth across Africa, and will be presenting his thesis on this. He has won a number of awards and is also an accomplished speaker who has delivered talks at the Wharton Business School, Harvard Business School, Cambridge University, the University of Ghana, and the TEDGlobal conference in Tanzania.

Spear and Chinery-Hesse are part of a line-up of African and international thought leaders from organisations like Amazon, HP, Johns Hopkins University, Mozilla, SwiftRiver, the African Institution of Technology, SimpleGeo, Motribe, Clearleft, Ultinet Systems and many more.

Knight adds, “With Tech4Africa our simple aim is to congregate the best practitioners in Africa and the world to provide inspiration, guidance, case studies, success stories and ultimately experience, so that Africans don’t need to travel the world to gain this understanding and exposure”.

]]> SA cellphone users suddenly smart http://blog.tech4africa.com/sa-cellphone-users-suddenly-smart/ Wed, 09 Feb 2011 10:31:01 +0000 http://t4a.feedmybeta.com?p=1077 Continue reading ]]> A research study released today shows that the cellular habits of South African phone users have evolved dramatically in the past year as smartphones, mobile applications and the mobile Internet entered the mainstream.

The Mobility 2011 research project, conducted by World Wide Worx and backed by First National Bank, reveals that 39% of urban South Africans and 27% of rural users are now browsing the Internet on their phones. The study excludes “deep rural” users, and represents around 20-million South Africans aged 16 and above. This means that at least 6-million South Africans now have Internet access on their phones.

“Approximately 30% of FNB’s 2.6 million Cellphone Banking customer base is in the middle income segment. During the festive period for example, the FNB.Mobi site, which is generally accessed by the tech savvy via the internet on their Cell Phones, attracted high volumes of visitors. Cellphone Banking is becoming the preferred alternative as people across the board are driven by the ‘anywhere, anytime’ concept of banking.” says Ravesh Ramlakan, CEO FNB Cellphone Banking Solutions.

The big winner in terms of sites and services is Mxit, which enjoys the attention of 24% of cellphone users aged 16 and above (29% of urban, 19% of rural users). However, Facebook is catching up fast, reaching 22% of users, and in fact passing Mxit in the urban over-16 market, with 30% reach, versus 13% among rural users.

Twitter will also become a key mobile tool, almost catching up to MXit in the coming year, from a low 6% of cellular users at the end of 2010. The proportion of urban Twitter mobile users is exactly double that of rural users: 8%, against 4%.

“Twitter is the big surprise of the study”, says Arthur Goldstuck, managing director of World Wide Worx. “But it is being pushed so hard by media personalities, its time had to come”.

The most dramatic shift of all, however, is the arrival of e-mail in the rural user-base and its growth among urban users. There has been a substantial shift among the latter, with urban use rising from 10% in 2009 to 27% at the end of 2010. While the percentage growth among rural users is lower, the fact that it was almost non-existent a year before means the 12% penetration reported for 2010 indicates mobile e-mail becoming a mainstream tool across the population.

While cameras, diaries and games continue to dominate the list of features used on phones, FM radio and music players have become part of a mobile “Big Five”. However, there is a significant difference in the features preferred by urban and rural phone users. Three quarters of urban respondents (75%) use their phone cameras, but little more than half of rural respondents (55%). Music players on the phone get the vote of 53% of urban users, versus 36% of rural users. Surprisingly, the gap is reversed when it comes to games on the phone: 54% of urban users enjoy these, compared to 65% of rural users.

The Mobility 2011 project comprises two reports, namely the Mobile Consumer in SA 2011 and the Mobile Internet in SA 2011. It is based on face-to-face interviews with a nationally representative sample of South Africans, conducted towards the end of 2010.

]]> SA startup selected as TechCrunch ‘Best New Startup’ http://blog.tech4africa.com/sa-startup-selected-as-techcrunch-best-new-startup/ Thu, 18 Nov 2010 11:04:44 +0000 http://t4a.feedmybeta.com?p=1047 The TechCruch Europas, the European Startup Awards for tech companies, has listed Cognician as one of the top 11 Best New Startup’s in 2010. The company is a South African technology startup founded by Patrick Kayton, who was a speaker at Tech4Africa 2010.

The Europas serve to honour the best technology companies and startups across the web and mobile space. The awards span 22 categories and recognise and celebrate the most compelling technology startups, Internet and mobile innovations of the past year.

Cognican, the original thought processor that presents content in the form of provocative questions, helping users to apply the author’s ideas to their own tasks, so that they can think better, further and faster, was selected through a process done by referencing TechCrunch’s database of tech companies on CrunchBase. This was followed by a month of online public voting that saw 33,126 votes being cast across all categories. The final award winners will be determined based both on popular votes received through website voting along with the results submitted by The Europas Advisory Board.

The award winners will be revealed at The Europas event which will be held in London this Friday, November 19. The evening will be attended by over 350 people from the cream of Europe’s startups, VCs and entrepreneurs along with industry leaders of the the tech startup and investor scene who will be presenting the awards to the winners.

Says Patrick Kayton, co-founder and COO of Cognician “We’re thrilled to be recognised through The Europas and we wish to send out a big thank you to everyone who voted for us. It is especially rewarding as the Europas finalists are determined by the tech community who were invited to have their say in which startups should be recognised. It’s quite remarkable that we’re there at all actually, as little or no votes would have been cast by our local network.

“Cognician has made great strides in 2010 with limited resources and see being nominated in the final 11 as testament to both the quality of Cognician and the work that our small team has put in,” adds Kayton.

“Prior to it’s soft launch in September Cognicain has won the Cape Town Activa competition in the Ideas Track. Later, we were selected as one of Africa’s top three startups at Seedcamp Week Johannesburg and we were finalists at Seedcamp Week in London.

Kayton explains that Cognician is currently making 70 original cogs for two leading corporate clients in The Allan Gray Orbis Foundation and Old Mutual. “Furthermore we’ve signed publishing deals with the UK-based publishers, Profile Books and Infinite Ideas which will enable Cognician to produce further cogs.

“To now be recognised as a finalist in The Europa Awards is the cherry on the top of 2010,” concludes Kayton.

By the time we got to the closing remarks at the end of two fantastic days at Tech4Africa, the atmosphere was a mix of exhaustion, inspiration and eagerness to get to the after party and then beyond into the world, to start applying the learning’s and following up with new connections made.

I had already started asking people what their number one take-away from the unconference-conference had been, so was delighted when the panel opened up their closing remarks along the same lines.

Hearing what other attendee’s pick out as their number one take away, is a great way to summarise the key points and highlight any trends from all the information that was imparted.

So here are some of the take-aways that were shared with me and that I picked up from the panel:

Simon Dingle declared that “Tech4Africa has arrived!”

Duncan McCleod is “going to make it a priority to come to next years Tech4Africa”.

Ivo Vegter felt that “our (as in South Africa’s) engineers and developers are at the top of their game”.

Andy Higgins said his take away was “to build small and good, rather than big and mediocre”.

“Only Africans are going to solve African problems. The international context is a great wake up call, but it needs to be applied to the African context by Africans. It’s only a matter of time before Tech4Africa is dominated by the rest of Africa’s start up’s and speakers. The time is now to look forward!” exclaimed Mark Kaigwa from Kenya.

Dustin Diaz was a man of few words, all he could say to me was: “Blown away!”

Whereas Darren Smith was a bit more verbose with his points, being: “T4A take-away: Seedcamp and Tech4Africa was an eye-opener, in as much meeting the local and international innovators brought home just how fast the world is moving, yet how small its boundaries have become (something that Clay Shirky alluded to in his keynote). What it brought home to me though, was the difficulty in bootstrapping a genuine tech start-up in this country. There seems to be a massive gap between the bootstrapped start-up, and genuine VC investment in a BUSINESS. Most of the entrepreneurs I chatted to and listened to during Tech4Africa were long on tech, passion and ideas, but short on business acumen. And in the absence of a degree of working capital, these start-ups simply will never start-up. Its simple economics.

Sadly, I left Tech4Africa with little semblance of sufficient support structures for entrepreneurs other than ‘family and fools’. It seems to me that most so-called boot-strapped business successes in South Africa are actually extensions of established businesses, products/services … and are funded through the working capital of their benefactors. VCs are looking for much bigger investment opportunities than offered locally (they’re looking for global scale, and 60% plus returns). Yet many of the innovations NEED to serve South Africa needs, and if that’s all they do, it doesn’t make them any less valuable.

So, a few mixed feelings. On the one hand, a tremendous fillip for tech innovation in Africa, but again a sobering assessment of our ability to harness the capital needed to put this innovation to work.”

Ashley Shaw summed up his take away as “solutions to challenges and meeting people”.

“I had a take away pizza last night” was what came to Gordon Greeff’s mind when I asked him, while Mongezi Mtati felt ”the conference has raised the bar much higher than before, the perception that innovation originates from somewhere outside Africa no longer holds true. The challenge is to transcend the needs of a select few who know what the web is about, and create applications that change lives.”

Renier Meyer asserted that “Tech4Africa was an awesome experience and all the panel discussions and presentations were very inspiring and made me think differently about lots of things and also made me think about things I’ve never thought of before. One thing that I realised is that we as South Africans and Africans, are different. And we do things a lot differently here than in the rest of the world. How we do things here even differs from how they do it in other African countries, I’m especially thinking about the mobile market. But even though its a lot different it works well for us and there are entrepreneurs that see opportunities to make these things that make us different, better for us.”

Jonathan Smit’s primary reason for going to Tech4Africa was to hear and meet the international speakers who we would normally not have access to. His take away was: “It was fantastic to hear from some of the great Internet minds from around the world and to connect with like minded Africans. The skills necessary to create, run and grow great Internet businesses abound within Africa and the learnings from our international colleagues can be readily applied to our context to achieve great success both locally and internationally.”

Irene Walker had this to say as her sum up: “The difference between good and great digital solutions lie in their consideration and implementation of satisfied user needs.”

My take away? I think that there is a lot of innovation in Africa, and the sharing of international best practice mixed with the out of box thinking from Africa which is driven by need, is going to see a lot of exciting new developments originating from Africa.

So what is your take-way?

Day 2

Day 2 of the Tech4Africa conference showed a much more relaxed atmosphere shown very evidently in the casual attire of the attendees. It was started off with a great introduction by Marcel Klaasen re-iterating FNB’s commitment to startups and a couple of his view on the state of entrepreneurship in SA.

Soon to follow was a very informal and highly interactive session on Social Media. With the panel all dispising the title of Social Media Guru’s I could help but notice that they all are about as close as you could get… maybe their definition was skewed, but they all seemed to fit the mould of being able to effectively use Social Media to enhance a companies brand – IMHO I don’t know what else would constitute a guru. The topic tended to sit quite heavily in the philosophical side of the media and less on the local case studies. This could this be to the distinct lack of local case studies (Outside of Cell C) but an interesting angle would have been what types of Social Media wold work for different companies? There definitely seemed to be a heavy focus on Twitter and Facebook, but what of Youtube of Flickr?

At the end of the day, the “success” of your social media campaign depends more on the quality of your product and how honest you are with your customers. Apple was highlighted for various reasons, but I think that the case highlights a very interesting point on how to maximise on social media by not interacting. I would have loved to see this discussion between the panel and the audience continue for about 3 hours, just to see what path it would follow and where it would polarize. This method my produce more concrete outcomes and more clearly highlight the relevant points.

The second talk was very different but just as interesting as the panel had taken a well known site and redesigned it. They led us through the very interesting process resulting in a much more effective site layout and flow. Although it was a great concept and they will give the content generated to Payfine.co.za to use as they will, it could have been taken a little further. Possibly with a bidding process by companies and the final product being sold to the company of choice with some of the funds going into sponsorship for the event. it could add a whole new level of hype.

Find here the slides of the presentation “How we redesigned PayFine.co.za, and why you need to know”.

Traditional media as a hotly contested topic was an interesting talk. Mostly due to the lack of continuity in definitions for the terms, with few points that they did agree on Bing that journalism is not only writing. It is all the background research and reporting that goes on. The Traditional Media model of finding a way to make revenue from any means possible and use that revenue to fund the journalism side. Apparently tablets will save Traditional Media by providing a more sexy, appealing way for us to receive verified news.

With a keynote by Clay Shirky to follow and then the afternoon session on entrepreneurship, startups and funding I’m really looking forward to what the last quarter of T4A 2010 has to offer.

Day 2

The day 2 Tech4Africa Tech stream kicked off with a presentation by Dustin Diaz, the lead Javascript Architect at Twitter, titled “Unobtrusive Interfaces with JavaScript”.

He began by telling us the story of his life, about his 4 dads and how he didn’t do well in school until 8th Grade, where he got straight A’s and discovered a passion for running. He ended up being ranked 13th in the US for the 800m, which got him a scholarship to the University of Sacramento. He has a degree in Spanish, which he says led him to JavaScript, as they are both foreign languages.. go figure.

Dustin has extensive experience in the online space, he worked at Yahoo! and Google before joining the team at Twitter in 2009. He authored the book “Pro JavaScript Design Patterns” with Ross Harmes.

His passions are JavaScript, Photography and Mixology (yes, making cocktails) and he says they overlap as all of them are expressive and allow you to strive for perfection. Dustin likens HTML, CSS and JavaScript to the Holy Trinity. He took us through the evolution of code and in his unique style, allowed the non-techies in the audience to understand why unobtrusive JavaScript is important.

Twitter’s new product ‘@Anywhere’ is his pet project. It is a cross domain API that allows you to embed JavaScript into your site and integrates with the Twitter API to perform a similar function to Facebook connect but, in Dustin’s words “ours is better because, let’s face it, nobody wants to code in FBML”. @Anywhere allows you to embed a tweet box in your site that enables you to tweet from anywhere, as well as ‘follow’ buttons which facilitate what he calls “frictionless following”.

Dustin’s favourite @Anywhere feature is that you now have direct access to the JavaScript API of Twitter, allowing you to write scripts that will find, follow, message, retweet and display the timeline of a user directly on your website without redirecting the user to Twitter.com

Dustin warned us to be careful before entering the world of JavaScript, “jQuery is like cocaine, one line and you’re hooked”. Hmmm, I’m not addicted yet but maybe I should try it because Dustin definitely makes code sound sexy.

For more on how Twitter built @Anywhere, have a look at this presentation.

Day 1

It’s going to be a flood of data as more people connect more often with their mobiles. Says Joe Stump (co-founder of SimpleGeo, previously main dev bod at Digg): “Each smartphone has six-plus sensors, and it’s not long before they add barometers and temperature sensors and more. Data production is following Moore’s Law.”

He did a simple calculation, working out what happens if you were to tag the phones (just time and location) once every minute for the 500 million Facebook users.
Just this little addition would add 37.2GB of data every minute to the piles that already need to be crunched.
He asks: “How are we going to store, scale and serve this mess?”
His main point is: scaling != performance.
Performance is more about i/o, and not so much in your choice of language. Choose Ruby, choose php, it makes little total impact to large-scale systems, he insists.
Mostly, scaling is a specialisation.
“The more traffic you get, the more specialised your infrastructure needs to be,” he says. The key is automation – bits should be able to be called or started or attached automatically. Use the cloud, but treat everything in the cloud as ephemeral. It can and will just disappear. Expect it.

He discussed the two approaches to scaling – namely out, and up.
If you scale out, you spread load across lots of boxes. If you scale up you get a bigger, faster box. Less complex infrastructure, but a really powerful box can cost millions of bucks – only workable if your service is making big money already.

Other gems of wisdom:
* Partition your data from the very beginning
* Make use of queues – very important part of consistency of user experience.
* Caching is critical – especially in supporting queues. Write a record to cache while it’s processed by queue so that user experience stays OK.

These are lessons learned from long years worrying about things like: how do you handle objects such as the front page story on Digg when it’s getting millions of hits?
His other key advice is about people:
“It takes a lot of people to build, scale and maintain infrastructure – you will grow from one or two to 15 or more.” The human management issues become tricky here: “The first two or three devs on board are going to question every decision management makes.”
A good thought: “Look for a trait in developers: laziness. You want someone who looks for a quicker, better way.”

As your site (and dev team) grows, he advises looking to lower barriers to entry for more junior devs. “Get your codebase to a position where you don’t need to hire a Jedi. Jedis are rare. Jedis are expensive.”
He recommends breaking teams up. 4-6 people work well, at 8 it starts breaking. Get a Jedi, and make them the team leader. Note: team leader, not manager. They should act more like a sports team’s captain. Create frameworks (authentication, error handling) to lower barriers to entry as new coders come on.
And use code repositories. Full stop.

He is very passionate about promote ownership in the codebase, so that individuals work on three of four areas and have responsibility for them.
“As you scale and your code bases grow, from 50,000 lines of code to 400,000 lines, no-one can be effective across the whole base,” he says.
Before you start, design the software – don’t just start coding. He is a big fan of stubbing out the API on a whiteboard.

When it comes to testing – automation is good, and use several methods. If you fix something, make sure you run a test on the old version and make sure it fails it. Apply patch, and make sure it now passes.
Documentation. Build time into your planning for documentation. Even if old and stale it adds historical context, maybe helping you understand later why you made a particular decision.
Do peer reviews. “I’ve never sat in on any peer review and didn’t see at least one show-stopping bug.”

There are a number of ways to scale up using powerful technologies. “When I left Digg we were handling 37,000 requests a second,” he says. Now at SimpleGeo, he runs 15 nodes in one Cassandra cluster, 12 nodes in other cluster.
The numbers will go up (if you are even remotely successful). The technology is getting faster and faster, handling volumes that would have been unthinkable before. “You can get 1500 writes a second on a decent SQL box. A couple of years ago if you asked me if I’d need that, I would have laughed,” says Stump. Right now he is putting 5,000 to 7,000 writes/sec on a Cassandra cluster.

Most South African web developers, even those working for the relative giants like news24.com see only a fraction of these volumes – but one thing is sure. Africa is developing its Internet community fast – it won’t be long before servers talking to thousands of users are talking to millions.

]]> Mesh Potatos Become Hot Potatos http://blog.tech4africa.com/mesh-potatos-become-hot-potatos/ Thu, 12 Aug 2010 15:57:48 +0000 http://t4a.feedmybeta.com?p=371 Continue reading ]]> News from the conference room: this is a series of blog posts in which blogging experts briefly review key Tech4Africa 2010 talks and panels from Day 1 and 2.

Day 1

The Tech track at Tech4Africa kicked off with a presentation by Steve Song, a Shuttleworth Foundation fellow and a founder of Village Telco project.
His main theme was the high cost of access to basic communications, and the solution developed that can help solve this problem. Which is always a good thing in a solution.
An eye-opening statistic: the bottom 75% income band in Africa spends 50% of their disposable income on mobile services (in SA it’s a touch lower, at 40%, although probably because people earn a bit more here than because our mobile operators are particularly cheap).
If you’re an economist you get to sit back smugly, take a sip of Merlot and say, “See, you see how much they value it? Clearly it delivers the incentive they believe makes it worth the price.” If you’re not an economist you kick them in the head.
If you’re an African leader you wake the hell up, and realise that without driving down the cost of telephone and data access, your people will struggle and struggle to advance (and hence build businesses that pay you tax revenues that leaders can in turn plunder for new presidential palaces, you bastards).
In Steve’s more considered words, “What might an enlightened African leader should say: ‘It’s the cost of access, stupid’.”
His main contention in developing businesses is that to enable innovation, you must lower the cost of failure. When failure is expensive, the lesson learned is to stop wasting money.
With greater communication, more sharing of knowledge and greater transparency across markets comes immediate and marked growth in GDP. A cheaper way to provide telephony services in Africa is vital, and since the mobile operators (and government regulators) are not coming to the party, other options must be found.
His talk then turned to an old Linksys wireless router, the WRT54G. Popular, now getting a little long in the tooth, but based on a Linux core in its firmware. Open Source types compelled Linksys to open up the code under GPL, and they dug in.
They hacked it, and discovered it was a pretty powerful box, with hardware (RAM, CPU, etc) more advanced than its as-shipped specs needed. A whole new industry of hacked WRT54G routers grew up… enthusiasts wrote books about it, codified the OS as OpenWRT.
You can unplug the stub antenna, and add a directional (such as a cheap, home-made cantenna), and talk reliably over many kilometres.
You could hook a bunch together over in a mesh over an area, plug a phone into it, hack it a bit more, and end up with the Mesh Potato.
Mesh, as in the Open Source mesh protocol developed substantially by a woman called Elektra in Germany, POTS as in Plain Old Telephone System (it works with old skool analogue telephone handsets) and an ATA (Analogue Telephone Adapter) to packetise the voice.
Mesh Potato. Get it? It’s cleverer in Spain, where they call them patatas.
The hardware for the box was designed by an Australian hardware engineer called Mr. David Rowe, and then mass produced.
Hacking together some code is easy enough, you may think, but a piece of hardware is an entirely different proposition.
Luckily, not true.
An interesting development, says Song: “Hardware is the new software. You can bring a unique hardware product to market quite quickly and cheaply.”
The Mesh Potato team finalised the design, did some prototypes for testing, then went into production with a manufacturer in China, who was only to happy to give them a good unit price in exchange for the know-how (yay for open source goodness and commodity technology like WiFi and open standards like SIP!).
The final device will be a fairly cute little white box that’s weatherproof (rain, dust and sun) with hardened ports that won’t fry its little heart if some klutz plugs the wrong thing in.
The mesh then connects up a number of standard handsets that can be pulled out the dumpster, allowing a non-profit to set up a local telephone network quickly and exceptionally cheaply.
The little network can be autonomous, or you can add a “server” that’s being developed that has a VoIP connection upstream to a gateway to allow interconnect to national operators.
Song recons they got a 400m range at a setup they ran at the Afrikaburn festival/party/freakshow in the Karoo in the Western Cape a few months back, and with a new version planned using 802.11n, they’re looking for even longer range.
The non-profit part is key, because these organisations can operate a network in many African countries free if they don’t charge. A small business can be set up to be a commercial venture, but then they’d need an ECS class licence (in SA, similar elsewhere).
The box was developed by a team that kicked around ideas and designs across South Africa, Kenya, Tanzania, Uganda.
Song says they’re so far not getting hostility from the incumbent mobile and landline operators, but probably because they’re flying well under the radar. The tolerance may change when the Mesh Potato starts to become widespread.
It’s an interesting future. In the past the only people with the ability to deliver a viable telephone network would have to do it on a national basis. Deep pockets. Exclusive licences. Monopolies. Price gouging. In incumbent operators’ defence, the price to pay for doing a national network is that it would have to meet minimum standards. Expensive, reliable, standardised technology. Think SS7.
That changes with repurposed commodity technology.
Now a village or area in a township can set up a telephone network that services just them cheaply and easily. If it falls over, they know exactly whose door to go knock on. It does the needed job. It’s cheap. It can be grown, and grown.
Rather like ISPs providing VoIP services to small businesses will eat into national operators, so small consumer meshes will eat into national operators.
Is this the democratisation and commoditisation of telephony? These small potatos?

(NOTE: Blogging for the event is done with little time and bandwidth. Apologies for any factual errors, but c’est la vie).

]]> Tech4Africa partners with First National Bank and Internet Solutions http://blog.tech4africa.com/t4a-partners-with-first-national-bank-and-internet-solutions/ Tue, 10 Aug 2010 10:10:07 +0000 http://t4a.feedmybeta.com?p=328 Continue reading ]]> FNB, Internet Solutions endorse African technology development through partnership with Tech4Africa

Internet Solutions and First National Bank (FNB) have given their full backing to Tech4Africa, the premier Internet and emerging technology conference, in their role as Foundation Partners and have committed to supporting the long-term development of home-grown technology solutions on the continent.

“From our earliest discussions with FNB and Internet Solutions it was evident that they share our values and vision for the future of Internet and mobile technologies on the continent,” says event organiser Gareth Knight. “The reality is that Africa is playing catch-up in these sectors and that this can only be overcome through collaborating with the best minds in the industry, locally and globally.”

“Both partners bring tremendous value to the conference because of their appreciation for the way in which technology can and should be applied to drive economic prosperity in Africa, and have clearly demonstrated their skills in this sector.”

Knight points to Internet Solutions’ position as a leading provider of Internet infrastructure across the continent. As the trusted partner in IP driven solutions, Internet Solutions enables their clients to be truly competitive in the global economy.

Company MD Derek Wilcocks says Internet Solutions’ participation extends well beyond its support of the conference and providing connectivity to participants over the two days.

“We see the future of the Internet in the way people are able to collaborate. Social media is changing the way organisations work and providing opportunities for governments to interact with their citizens,” he says. “The conference topics are at the heart of the future of our industry and we want to be part of that learning experience and also contribute to that debate.”

“For us, it’s about more than the technology and technical ability, it’s about the impact that we as an organisation can have on people’s lives,” he adds.

Knight says that FNB’s role as an enabler of business and technology ideas is equally important and that the bank’s participation at Tech4Africa will hopefully spur on more home-grown development.

“FNB has demonstrated a strong entrepreneurial edge and willingness to invest in the market through introducing technology-driven solutions such as PayPal and cellphone banking. In short, they are walking the talk, which other institutions are still struggling to achieve,” he says.

FNB Commercial’s head of small business sales, Marcel Klaassen, says FNB is continuously driven by innovation, which is based on a strong entrepreneurial spirit within the division.

“We recognise the role that technology, e-commerce and innovative banking solutions play in the entrepreneurial environment and are proud to facilitate knowledge sharing and international best practice trends in these areas,” he says. “We understand that the most difficult barriers for entrepreneurs to overcome is the lack of support and mentorship and have therefore tailored a business proposition around small businesses that address both their financial and non-financial needs. We look forward to engaging with existing and aspiring technology entrepreneurs.”

Tech4Africa 2010 will be featuring international and local technology visionaries including Clay Shirky, Leila Chirayath Janah, Jonathan Snook, John Resig and many others who will be sharing their knowledge and experiences. The conference is taking place on 12 and 13 August 2010 at The Forum in Bryanston, Johannesburg.

]]> Last but not least… http://blog.tech4africa.com/last-but-not-least/ Wed, 04 Aug 2010 13:03:27 +0000 http://t4a.feedmybeta.com?p=268 Continue reading ]]> A few last things about the conference, before things become totally manic.

We’ve got around 65 speakers over 2 days. I’m really excited about the depth of knowledge and experience that folks like Andy Budd (Clearleft), Alex Hunter, Erin Caton (Apple), Joe Stump (SimpleGeo), Jonathan Snook (Yahoo!) and Dustin Diaz (Twitter), will bring to Tech4Africa. These guys are really amazing at what they do, and are also awesome people, so anyone at the conference is in for a treat. Take 5 minutes to checkout the full line-up if you haven’t done so.

I think you’ll agree it’s a great line-up, which represents a good mix of business and technical people, and offers great content to delegates. More than anything, this is a first in Africa, and it’s largely down to your willingness to be a part of it. For that, I thank you. I hope you can spend the two days of the conference learning, absorbing, and enjoying. There is a team of 19 full time people working on Tech4Africa, to make it the event we’d all want to go to.

We’re now working pretty much 24/7 to make this event something that we would aspire to attend.
I’m not saying that lightly. Like you, I’ve been to my fair share of conferences, and in general I find most of them bland and uninteresting, with too many exhibitors.
So, I’ve tried really hard to make this one the conference that I would want to go to. My litmus test is: would I spend my hard earned cash and go to Tech4Africa? Would my friends do the same? I’m happy to say that right now the answer is yes, and I hope that once you’re there and you’ve experienced it for yourselves, the hard work and attention to detail will be apparent, and you’ll feel the same way. Ultimately though, all we can do is provide the right environment for the speakers to shine.

The focus is on interaction, discussion, engagement, debate and learning. The focus is on you.
Unlike a lot of conferences where you go listen to someone stand behind a lectern and run through powerpoint slides, essentially giving a lecture, we’re creating an environment where everyone will either be standing, or sitting on a couch with a bunch of other people. Our focus is 100% around delegate value, and this comes through real discussion and if needs be real arguments. It also comes through the audience feeling like they’re there being engaged with, and not lectured in a one-way environment.

As a quick reminder, online registration and payment for conference tickets closes at 1pm on Tues 10th August. If you would like to register after that, then please do so on site. Registration will be open at the venue from 1pm on the 11th of August (badge collection and/or registration). Please note that we will not accept cash, and that when the venue is full, we’ll have to turn people away. For conference registrations go here.

There is a conference “after party”, which will be on Friday night (August 13th), so please book that in your calendars, get the babysitters in, bring your significant other, and join us for some fun! RSVP on the event’s Facebook page.

And lastly, expect the “unconference”: don’t wear ties, don’t wear suits, bring your sense of humour, and enjoy yourself!

It’s going to be an awesome event, and I can’t wait to see you there

Regards,
Gareth Knight

]]> Let’s talk development at Tech4Africa http://blog.tech4africa.com/lets-talk-development-at-t4a/ Fri, 30 Jul 2010 12:03:02 +0000 http://t4a.feedmybeta.com?p=211 Continue reading ]]> The countdown has begun, and with less than 2 weeks till the most diverse and unique conference in South African tech history kicks off, all the last minutes plans are being put into place. We can’t wait for the doors to open and introduce you to some of the most prolific speakers from both South Africa as well as internationally.

A big focus at Tech4Africa will be focused on development and how local startups can benefit from learning from some of the best Developers from the biggest platforms around the world. Guys like Dustin Diaz from Twitter & John Resig from Mozilla are just some of the big names to join us at Tech4Africa.

Jonathan Snook from Yahoo will be looking at how iPhone & Android development are growing rapidly, and how you can create the perfect and usable app. Jonathan comes from a long history of web development and developing apps, and will no doubt share his fantastic knowledge on these topics.

Another session not to miss is by Andy Budd, who is an interaction designer and web standards developer from Brighton, England. Andy leads the user experience team at Clearleft, and will be hosting a session called “Ignore User Experience at your peril”. User experience is essential when developing a new product, and Andy will take us through the steps to ensure it is done 100% correctly.

With Twitter growing daily in leaps in bounds, Lead User interface engineer, Dustin Diaz, will be sharing his tips & tricks when developing with Javascript. In his session called “Unobtrusive interfaces with js” will assist developers in ensuring user interfaces are are always rich & engaging.

Another Javascript ninja, John Resig, will be presenting a session called “6 secrets to becoming a jQuery ninja”, in which John will be showing you the tricks of the trade on how to become the ultimate jQuery ninja. John comes with a wealth of jQuery knowledge is the lead developer of the jQuery Javascript library.

If there is one session you do NOT want to miss at Tech4Africa, it will be the Q&A session with all these guys, joined by Joe Stump from SimpleGeo. Andy Budd, Dustin Diaz, John Resig, Jonathan Snook & Joe Stump will all join in a 1 hour Q&A session panel, where they will be answering your questions as well as answering an interesting question – “What was your hardest challenge, and how did you overcome it?” Be sure to join the guys on the Thursday at 11:00

It’s not only the international chaps who will be sharing their experiences with you, we have a fantastic South African panel called “Ideas are cheap, execution is everything. Live to bootstrap.”
The panel will be headed up by Brett Haggard who is joined by Barbara Mallinson from Obami, Eve Dmchowska from Crowdfund, our very own Gareth Knight from Technovated & Andy Higgins from BidorBuy. The panel will look at how South Africans need to bootstrap their product and without losing perspective or faith.

Last but not least we will also be hosting Erik Hersman who was the man behind the ever popular African open source project Ushahidi, which allows users to crowd source crisis information to be sent via mobile. Erik will share his story on how Ushahidi has grown into the international success it is today.

With a lineup like this, you cannot afford to miss Tech4Africa this year. If you have not registered your place yet, we suggest you do so ASAP. Places are running out fast, this is one conference you do NOT want to miss out on !
