What the Heck Can We do With Our GIS?

Reading this article on the Mindsumo blog I remembered not too long ago we had engineers in Lagos aggregating GIS information for the state.

So I wonder today, where is this information and how can we (residents) leverage it or build innovative solutions that would solve some of the city’s pressing challenges?


Following below is an excerpt of the post:

According to the worlds greatest source of knowledge, the legendary Wikipedia, a Geographic Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. Put a little more simply, a GIS is the merging of cartography, statistical analysis, and database technology. Put even more simply, it tells you the stuff that’s in an area, bro.

A GIS contains a record of the geographical information in an area, details on what occurs there, and can predict what the consequences of changing the geography would be. For example, engineers use a GIS before deciding to build a new road to determine if it will even have a positive impact on traffic flow in an area. One could also be used to find a suitable location for a construction project by searching for an area with 5,000 square meters of free space, soil types appropriate for the scale of the building, and within 500 meters of a road. A wide variety of information about traffic habits, elevation levels, population density and socio-economic factors can be recorded and put to use in a GIS.

The question we want answered at MindSumo is: What would you do with one? How would you build a more prosperous and industrious city using all the different types of geographical information available? Build windmills to provide power in large flat areas? Gather the largest construction projects in the areas least prone to an earthquake? Place housing at the top of hills to avoid flooding? There are infinite ways to use the vast amounts of data we are now able to gather about the areas we live in, so how will you work them to your advantage?

The New Etisalat Free Internet browsing Tweak

A few days ago, I saw a thank you message in my mailbox from a faithful reader on how he’s been able to browse free with his Etisalat SIM after our last chat. His reaction went like this;

…good evening Mr Ahmsta… I have good news for you…. After the last mail I sent to you, then the next day my MTN BB subscription expired. Then I just made up my mind to use Etisalat for a trial. I started with daily BB subscription for N100. Then I inserted the exact settings as you posted for MTN. But surprisingly after my subscription expired, I could still browse, free of charge. I am still using it. Oga you really tried a lot… I can’t say it’s my work but it’s your words of encouragement that made me win, cos if you could remember when I asked you if the settings would work for other networks you said its only tested on MTN, but believed it would also work for the other networks…

Thanks my oga, God bless. 1love!!!!!!

Real good news, isn’t it? Well I thought of getting the full details on how he did it because I have limited time in testing and yes… It’s just the same as I posted previously, in other not to waste much time talking about stuff behind let me go straight away to how he was able to do it

How To Setup The New Etisalat Free browsing.

First all you have to do like he said above is to recharge a N100 on your mobile,

After that, then you need to subscribe for the etisalat internet blackberry plan by dailing *499*3*2#, Few minutes after that yo will get an SMS message like the following:

Welcome to the Etisalat blackberry Complete voice plan.

That’s all you’ll need. Restart your mobile then configure your gadgets like this


Connection name : Ahmsta Connection

Data Bearer: Packet data

Access point name: blackberry.net

Username & Password : web

Authentication: Normal

Homepage: http://www.ahmsta.com

After filling those, then click option >> Advance settings

Network type : IPv4

Phone IP address : automatic

DNS adress: (primary:, then secondary:

Proxy Server Address:

Port: 8080

For your computer just configure your browsers / applications to use you can use the same configure for the MTN Bis or rather use this

Access point – blackberry.net

Click Advance and set your DNS as follows

DNS address: (primary:, then secondary:

Proxy address:-

Port:- 8080

That’s all,

In this case, Ultrasurf is not really needed, but if you still use it, it will sure work

NOTE: Its likely you get billed if you recharge while using this, so its better you opt out before you recharge your account.

Thanks to you Nibras Muhammad.
