During one of our visits at Konza City, Machakos county in Kenya, my team and I encountered a big problem accessing to viable water. Most times we enquired for water, we were handed a bottle of bought water. This for a day or few days would be affordable for some, but for a lifetime of a middle income person, it will be way too much expensive. Of ten people we encountered 8 complained of a proper mechanism to access to viable water. This to us was a very demanding problem, that needed to be sorted out immediately. Majority of the people were unable to conduct income generating activities such as farming because of the nature of the kind of water and its scarcity as well.
Such a scenario demands for an immediate way to solve this problem. Various ways have been put into practice to ensure sustainability of water conservation and management. However most of them have been futile on the aspect of sustainability. As part of our research we also considered to check out of the formal mechanisms put in place to ensure proper acquisition of water, and one of them we saw was tree planting, which was not sustainable at all, also some few piped water was being transported very long distances from the destinations, this however did not solve the immediate needs of the people.We found out that the area has a large body mass of salty water which was not viable for them to conduct any constructive activity. This was hint enough to help us find a way to curb this demanding challenge. Presence of salty water was the first step of our solution.
We came up with an IOT based system to help curb this problem. Our system entails purification of the salty water through electrolysis, the device is places at an area where the body mass of water is located, it drills for a suitable depth and allow the salty water to flow into it. Various sets of tanks and valves are situated next to it, these tanks acts as to contain the salty water temporarily. A high power source is then connected to each tank, this enable the separation of Chlorine ions from Hydrogen Ions by electrolysis through electrolysis, salt is then separated and allowed to flow from the lower chamber of the tanks, allowing clean water to from to the preceding tanks, the preceding tanks contains various chemicals to remove any remaining impurities. The whole entire process is managed by the action of sensors. Water alkalinity, turbidity and ph are monitored and relayed onto a mobile phone, this then follows a predictive analysis of the data history stored then makes up a decision to increase flow of water in the valves or to decrease its flow. This being a hot prone area, we opted to maximize harnessing of power through solar power, this power availability is almost perfect to provide us with at least 440V constant supply to facilitate faster electrolysis of the salty water.
Being a drought prone area, it was key that the outlet water should be cold and comfortable for consumers to use, so we also coupled our output chamber with cooling tanks, these tanks are managed via our mobile application, the information relayed from it in terms of temperature and humidity are sent to it. This information is key in helping us produce water at optimum states, enabling us to fully manage supply and input of the water from the water bodies.
By the use of natural language processing, we are able to automatically control flow and feeing of the valves to and fro using Voice, one could say “The output water is too hot”, and the system would respond by increasing the speed of the fans and making the tanks provide very cold water. Additional to this system, we have prepared short video tutorials and documents enlighting people on how to conserve water and maintain the optimum state of the green economy.
IBM/OPEN SOURCE TECHNOLOGIES
For a start, we have implemented our project using esp8266 microcontrollers, sensors, transducers and low payload containers to demonstrate our project. Previously we have used Google’s firebase cloud platform to ensure realtimeness of data to-and-fro relay to the mobile. This has proven workable for most cases, whether on a small scale or large scale, however we meet challenges such as change in the fingerprint keys that renders our device not workable, we intend to overcome this problem by moving to IBM bluemix platform.
We use C++ Programming language for our microcontrollers and sensor communication, in some cases we use Python programming language to process neuro-networks for our microcontrollers.
Any feedback conserning this project please?8

So proud to know other great people world wide such as Ambassadors from other countries .Big up Farooq Hassan for giving us good directions and most above all Eng. Hezbon orina for giving the spirit to always move on. 🎊2
Hey folks, this is ben.
Just a little story of me and IOT
,for the past few months, i have been working on various projects on Internet of Things and, with the little exposure... I have seen so much goodies that come along, i love the robust and realtime architecture that IOT has, on my platform i use
Arduino, esp8266 and Android, i am able to control my car park, home lights, and my pulse rate using the few components.
At first it was hustle, but now? Am loving it😋😋😋,
If you wish to join me or have a project of the sort..... Just holla me up :firstname.lastname@example.org
I can also teach for free.13
What is in a web name?
thought i would share
www.gotahoe.com (go tahoe )
www.speedofart.com (speed of art designers)
www.whorepresents.com (who represents celebrity rep lookup site)
and of finally

Front-end dev: email domains other than Gmail and Hotmail exist?!1! 😱 And email regex, what the hell is that? 😵31
I'm not a ranty person so I never actually thought I'd post anything here but here it goes.
From the beginning.
We use ancient technologies. PHP 5.2, Symfony 1.2 and a non RFC complient SOAP with NO documentation.
A year ago We've been thrown a new temporary project. An VOIP app for every OS.
That being iOS, Android, MAC, PC, Linux, Windows mobile. With a 3 month deadline. All that thrown at 4 PHP developers. The idea being that They'll take it, sign the delivery protocol, everyone happy. No more updates for the app needed. They get their funds they needed the app for and we get paid.
Fast forward to today...
Our dev team started the year with great news that We'll most likely have to create a new project. Since the amount of new features would be far greater than current feature set, we managed to finally force our boss to use newer technologies (ie. seperate backend symfony4 PHP7+/frontend react, rest api and so on). So we were ecstatic to say the least. With preestimates aimed at a minimum 3 month development period. Since we're comfortable with everything that needs to be done.
Two days later our boss came to me that one of our most annoying clients needs a new feature. Said client uses ancient version written on a napkin because They changed half of the specification 2 weaks before deadline in a software made not by a developer but some sysadmin who didn't know anything. His MVC model was practically VVV model since he even had sql queries in some views. Feature will take 3 days - fixing everything that will break in the meantime - 1-2 months.
F*** it, fine. A little overtime won't kill me.
Yesterday boss comes again... Apparently someone lost a delivery protocol for a project we ended that half a year ago. Whats even better at the time when we asked for hardware to test we never got any. When we asked about any testing enviornment - nothing. The app being SEMI-stable on everything is an overstatement but it was working on the os'es available at the time. Since the client started testing now again, it turns out that both Android app does not work on 8.1/9 and the iOS app does not work on ios12. The client obviously does not want to pay and we can do little with it without the protocol, other than rewriting the apps.
It will take months at least since all of those apps were written by people that didn't know neither the OS'es nor the languages. For example I started writing the iOS one in swift. Only to learn after half of the development time, that swift doesn't like working by C Library rules and I had to use ObjC also. With some C thrown in due to the library. 3 unknown languages, on an unknown platform in 3 months. I never had any apple device in my hand at that time nor do I intend to now. I'm astonished it worked out then. It was a clusterf**k of bad design and sticking everything together with deprecated apis and a gum. So I'll have to basically fully rewrite it.
If boss decides we'll take all those at the same time I'll f***ing jump of a bridge.8
--- HTTP/3 is coming! And it won't use TCP! ---
A recent announcement reveals that HTTP - the protocol used by browsers to communicate with web servers - will get a major change in version 3!
Before, the HTTP protocols (version 1.0, 1.1 and 2.2) were all layered on top of TCP (Transmission Control Protocol).
TCP provides reliable, ordered, and error-checked delivery of data over an IP network.
It can handle hardware failures, timeouts, etc. and makes sure the data is received in the order it was transmitted in.
Also you can easily detect if any corruption during transmission has occurred.
All these features are necessary for a protocol such as HTTP, but TCP wasn't originally designed for HTTP!
It's a "one-size-fits-all" solution, suitable for *any* application that needs this kind of reliability.
TCP does a lot of round trips between the client and the server to make sure everybody receives their data. Especially if you're using SSL. This results in a high network latency.
So if we had a protocol which is basically designed for HTTP, it could help a lot at fixing all these problems.
This is the idea behind "QUIC", an experimental network protocol, originally created by Google, using UDP.
Now we all know how unreliable UDP is: You don't know if the data you sent was received nor does the receiver know if there is anything missing. Also, data is unordered, so if anything takes longer to send, it will most likely mix up with the other pieces of data. The only good part of UDP is its simplicity.
So why use this crappy thing for such an important protocol as HTTP?
Well, QUIC fixes all these problems UDP has, and provides the reliability of TCP but without introducing lots of round trips and a high latency! (How cool is that?)
The Internet Engineering Task Force (IETF) has been working (or is still working) on a standardized version of QUIC, although it's very different from Google's original proposal.
The IETF also wants to create a version of HTTP that uses QUIC, previously referred to as HTTP-over-QUIC. HTTP-over-QUIC isn't, however, HTTP/2 over QUIC.
It's a new, updated version of HTTP built for QUIC.
Now, the chairman of both the HTTP working group and the QUIC working group for IETF, Mark Nottingham, wanted to rename HTTP-over-QUIC to HTTP/3, and it seems like his proposal got accepted!
So version 3 of HTTP will have QUIC as an essential, integral feature, and we can expect that it no longer uses TCP as its network protocol.
We will see how it turns out in the end, but I'm sure we will have to wait a couple more years for HTTP/3, when it has been thoroughly tested and integrated.
Thank you for reading!27
The presentation went great yesterday.
It was great to see all the kids who are interested in robotics.5
