Past and future

Today for me marks four years of post-college work.

I’ve been from one end of this country (Kilifi) to the other (Kisumu), working for various organizations that, basically, do good. Some of those organizations try (and somewhat succeed) at charging a fair price for a reasonable product. And others brave through thousand-page manuals of big-donor regulations as a necessary evil.

Planting my first eucalyptus

And I’ve been building technology systems where it’s kind of hard to do so. From mobile survey tools on basic feature phones to support rural tree farmers with  KOMAZA, to applications to run schools in some of Kenya’s most challenging slums with Bridge. And of course, web and mobile logistics to tackle rural supply chain distribution IPA/DSW.

I’ve also been a strong part of the tech community in Kenya. With Akirachix, I’ve organized country-wide tech workshops to teach students app development. I’ve also taken part in, won, and even judged some of the ubiquitous app competitions so notorious in this region.

So now I’m packing up, and preparing to begin a new chapter in my life at business school. As I look back on the past four years, and think about how I’ll use the next two, a couple things stand out for me:

  1. I want to stay in technology. It’s in my blood, it’s my passion, and it’s what is transforming Africa (despite the Kenyan government doing stupid things like kicking out the man who brought Kenyan tech forward by leaps and bounds).
  2. I want to do good. I don’t want to just sell widgets and increase dividends for fat-cat shareholders. However, non-profit or profit-making is irrelevant. After all, one could argue that Safaricom is the biggest social enterprise in Kenya.
  3. The technology scene in EA is missing something.  Too  many techies and not enough salesmen, marketers, financiers. Too many app challenges and not enough businesses. When I was at iHub Research trying to find businesses to interview for the Mobile BoP study, we were hard pressed to find many successful (i.e. profitable) mid-sized tech businesses (that were born in this recent tech-boom). Most entrepreneurs we talked to were still in pilot, launch or idea mode.

These thoughts will guide my next two years. I’ll be in the mecca of technology, Stanford and Silicon Valley, and I can’t wait to figure out first-hand how these techies turned their ideas into useful (indispensable) products into profits. Because that’s what the Kenyan economy needs and is poised for. And I’m very excited.

Getting Things Done

Every since a former colleague of mine introduced me to the Getting Things Done system over a year ago, it’s been a crucial tool in my life. What I love most about it is that you can implement as much or as little of the system as you’d like, and it will still make a big difference in your productivity. When I got started, I only implemented GTD to my email, and got my inbox down to ZERO – which by itself was a major win.

What is GTD? It’s turning all your stuff into real, actionable items that you can DO and be done with.

I recently gave a presentation introducing GTD, so I thought I’d share my deck here. Let me know @marialangat if you have any questions about the presentation or GTD in general!

Google Plus, now what?

So … now what?

I got my G+ account back when it was invite only. I felt cool. I felt like one of Malcolm Gladwell’s early adopters. I was won over by the innovative look and feel – all that white space has to be a good thing, right?

I added new friends. Well, since it was invite-only, there weren’t so many of my actual friends on there. Only other early adopters. Other internet and social geeks. Who were already my friends on Facebook and Twitter and FourSquare. Even when membership opened up to the public, my actual friends and family didn’t want or need another Facebook, so I found myself adding former school mates and really, anyone whose name I recognized, however tenuous the relationship. But that’s Ok! There were Circles! The Circles feature is supposed to be the Facebook killer, cleanly solving all the privacy issues that have confounded Facebook and frustrated it’s users.

So now, a couple months later I have a social network filled with people I don’t really know, and I triple-post my status updates on Twitter, Facebook and now Google Plus.  Um… now what?

So far, G+ does what FB does, and sometimes does it better. But it really must go above and beyond, and give us something that is not available on all the other existing networks. Otherwise, it will die a slow boring death. I’m already bored. And I’m an early adopter!

How do you use Google Plus?

We can have IT all

Yesterday, Women @Google Africa and AkiraChix co-hosted a Women in Tech Cocktail at the iHub. It’s always great to see so many self-professed female tech geeks gathered together. We had some special guests, including Olga Arara, Google Kenya’s new Country Manager, and Margaret Lisowiec a Google Software Engineer based in Zurich. In addition, there were many of the “usual suspects”, young Kenyan women making in impact in technology, including m-farm’s Jamilla, iHub manager Jessica, Google’s Shikoh Gitau and Jacqueline Rajuai. The ladies of Akirachix were also in attendance: @mariegithinji,  @Lkamau, @owigarj, @g33kmate, @rosewkaranja, @kiguruc, @AngieNicoleOD, @gkitony and yours truly, @marialangat

Most inspiring was the talk by Olga Arara, Google Kenya’s new Country Manager. Olga has had an exceptional career in Kenya’s business and technology fields, and has an Engineering undergraduate degree and MBA in Engineering Management. She shared with us her trailblazing career progression, and how she balances work, her marriage and family, and her personal development while making it look easy.

Naturally for such an event, we got into how to succeed as women in technology, a traditionally male-dominated industry. Olga’s advice was to “remove our blinders” and self-imposed limits. She emphasized the importance of not limiting yourself by defining yourself only as a woman. She also emphasized letting excellent results speak for oneself. While I agree that we shouldn’t preface our every statement with “As a woman I think… “, it is still important to recognize that there are very real barriers to success for women and other minorities. This is why I firmly believe that it is important to keep organizations like Akirachix active, organizations that have the specific mission of helping women succeed in their fields despite institutional barriers.

Another great subject that Olga addressed was work-life balance. Olga  is 39 years old and has two children. She has been married for 16 years and draws a lot of strength from her family life. Olga emphasized the importance of making time for friends and family. She keep a strict 8-5 schedule, which encourages her to perform optimally when at work, while allowing her meaningful time for her family, friends and personal development.

Solar powered laptop … released in Russia

Samsung has released a solar powered laptop, that may offer a battery life of up to 14.5 hours. Where can I sign up, you ask? Take the next flight to Moscow, because these machines are being initially offered in Russia. Apparently they were unveiled at the Africa Regional Forum right here in Nairobi, but I am puzzled as to why Samsung didn’t take the next logical step and release them to the Kenyan market. After all, we seem to be exactly the right market for this product – a growing technology hub, lack of electrification in many parts of the country, and plenty of sunshine (although you wouldn’t know it from looking out the window at this very moment).

Barcode scanner for zebras

A joint team from the University of Illinois at Chicago and Princeton University has combined technology, biology and conservationism in a cool new open source app called StripeSpotter that identifies zebras by scanning their stripes in a way that’s similar to a supermarket barcode reader.

The system itself uses image recognition algorithms on photographs taken in the field. It’s efficient – written in C++ with plain text csv data storage. They also capture GPS coordinates – presumably with the camera/phone that captures the photographs or separately with a separate GPS device. The basic requirements to start using StripeSpotter are a digital camera and laptop – take a photo, load it on to the laptop and run the StripeSpotter application. Seems like it would be a logical next step to make this a mobile device app so that game wardens can photograph and identify zebras right on the spot and thereafter sync up to a shared server to distribute the tagging work – crowdsource, if you will.

The team is currently compiling a database of Plains and Grevys zebra here in Kenya. The technology has the potential to be used by other striped animals eg tigers, and other animals with distinguishing markings eg leopards and giraffes.

Too good to be true – Facebook ad for US Masters degree scam

I’ve been seeing a Facebook ad recently that advertises a MS in Computer Science in the US. I idly clicked on it, and as I read, I started thinking that I’ve hit on a gold mine. Well, when something looks too good to be true, it usually is.

The ad led to a webpage that advertised a two year Masters in Computer Science from Maharishi University of Management. Red Flag one – what kind of a name is that for  a US college? But I’m keeping an open mind, after all, a lot of people think that Barack Obama is not American enough.

The big sell for the program  was that of the two years, 7-8 months would be in class, while the rest of the time the student would be working full time for  up to two years. The website claims that most of its students find employment in well known companies and they cite Google, Microsoft, Amazon and other heavyweights. The financial aid package is equally enticing. Basically the school gives you a loan of close to 100% of the course cost, and you repay as you start working full time during the program.

So, a virtually free Masters program with the (almost) guarantee of well paying job in the US? Where do I sign???

Well, that’s when the doubts start to creep in. If this program is really what it claims to be, there should be tens of thousands of people beating down their doors to get in.  They should be extremely exclusive. Yet the requirements of admission are disturbingly few – they don’t even require the GRE. The website has  a sample of the programming test that they administer – and it’s Programming 101, as in, find the second largest number in an array – very strange as this is a Master’s program ostensibly for someone with a Bachelors in CS and a couple years work experience.

They try to slip a seemingly innocuous sentence in there –  “You’ll learn a scientifically validated and well-documented technique for personal development, the Transcendental Meditation® program.” Hmm. Why should this you need to mention this when I’m looking at a Computer Science degree? Well children, it’s because that sentence is the most  gentle and non-alarming way to let you know that, um, you’re about to join a cult. Apparently this Transcendental Meditation is compulsory, no matter your religious beliefs or capacity for choice. One man’s ooga-booga or woo-hoo is another man’s religion, and there are plenty of Chrisitian based institutions that are legitimized and expect students to follow certain general rules, eg Notre Dame, or our own Strathmore. However, one student complains that they have up to four mediation sessions a day. Another claims that refusing to take part in the meditation results in being shunned by the community, or even your grades being lowered.  Googling Transcendental Mediation brings up all you need to know about this cult. TM as they call it, was to the 60/70s what Scientology was to the 90/00s.  Crazy celebrities and all.

Another message board warns that even the loan program is not what it seems. Students hardly have anything left over after the monthly loan repayments, and resort to borrowing from banks at high interest rates to live and continue their programs.

So the program, with it’s aggressive marketing recently targeting Kenya, seems to be a combination of a financial money maker and a breeding ground for new converts. In the worst case, you’ll be in debt in a foreign country and a member of a crackpot cult.  But in the best case scenario, you’ll have a frustrating two years of your life, have a fairly useless degree but perhaps you’ll be able to secure a US job based on your former experience. People have done crazier things to go abroad.

Would you risk the cult for the chance to work in the US?
