Start building an IoT gateway HTTPS program on the Ubuntu Linux platform

Many ARM IoT platforms support Ubuntu Linux. Once we've selected an IoT gateway hardware board, we then can put this image into the board and start running Ubuntu. This Ubuntu on an IoT board actually is just like your desktop PC. It provides web browser, editors,.., and so on. Once we link the board into internet and enable the auto ethernet from the desktop, we can start our development of the https application program.

First, we should download an openssl example program:

http://www.ibm.com/developerworks/linux/library/l-openssl.html

Then we can start the trial as follows:

-Edit sources.list file
$ sudo vi /etc/apt/sources.list

Insert the following lines:

deb http://ports.ubuntu.com/ubuntu-ports/ trusty main universe restricted
deb http://ports.ubuntu.com/ubuntu-ports/ trusty-security universe
deb http://ports.ubuntu.com/ubuntu-ports/ trusty-updates universe

-Update apt-get

$ sudo apt-get update

-Install gcc and libxml2

$ sudo apt-get install gcc

$ sudo apt-get install libxml2-dev

-Compile program

$ gcc test.c -I/usr/include/libxml2 -lxml2 -o test

-Test program

$ ./test

-Install libssl,pkg-config

$ sudo apt-get install libssl

$ sudo apt-get install pkg-config

-Check libs needed by libssl

$ pkg-config --libs libssl
-lssl -lcrypto

•-Compile and link libs

$ gcc nossl.c -I/usr/include -lssl -lcrypto

The Key Components of a Perfect Pitch to Your Investors

    There is an article "The 7 Key Components of a Perfect Elevator Pitch" posted by Noah Parsons at the bplans website. It mentions that there are seven key components that must be listed on our pitch to the investors. We'd better cover these seven topics on an A4 size paper as an abstract and present it to our target audiences within 60 seconds. 60 divided by 7, that's about eight seconds for each topic. It means that one or two sentences for each topic.

    Most of the time we always started with what do we want to do, what our products/services are. But the first thing we should think about is: what is the problem we'd like to solve. If no problem can be solved by our products then there will be no feasible business to do.

    Once we have a problem to solve, then we can describe how do our products/services solve it. And to whom do we sell our products/services.

    Goals are clear now. We now need to find out who is standing between customers and us. They are the barriers of our business. We must identify them to differentiate ourselves and create a unique selling point.

   Finally, we should describe who are our team members, how much money we are going to spend and how long will we achieve our goals.

CubicPower New York Maze: a 3D street VR viewer

Let's try to click the CubicPower New York Maze Index-Aa as follows:

http://www.cubicpower.idv.tw/BigData/NewYorkMaze/locations/Aa.htm

We can see lots of names with an Aa prefix and the street names like:

New York Maze index-Aa

AA Bus-E Broadway New York

AA Ichiban Sushi-7th Ave New York

AA Ichiban-W 28th St New York

AA Nails Spa-Pine St New York

AA Stylist Barber Shop-34th Ave New York

AAA Ami Vegetarian-2nd Ave New York

AAA Architectural Hardware-W 46th St New York

Aaa Auto Body Shop-W 38th St New York

AAA Cleaners-Ave A New York

AAA Dental PC-W 48th St New York

Aaa Glass Plus-Avenue C New York

AAA Ichiban Sushi-Orchard St New York

AAA Laundry-2nd Ave New York

AAA Marrakech-E 7th Street New York

AAA Range INC-W-37th St New York

Aaa Super Nail Salon Incorporated-3rd Ave New York

AAA Towing Service-351st New York

AAA-Broadway New York

A AAA Alliance Moving Inc-St 102 Albemarle New York

A A A Apple Dell Gateway Repair & Data Recovery-W 71st Street New York

A A A Federal Home & Building Inspections-York

AABC Plumbing-East 112 St New York

Aabc Plumbing-W 35th St New York

AAC Realty Corporation-Flatbush Ave New York

......

Click any of them like AA Bus, then we can see a map at the top of the screen and a 3D WebGL VR scene of street beneath.

Click the 3D view,hold the left button and move the mouse forward. Actually you are moving the camera forward. Then try to move the camera backward. You will see a bigger view angle of the street.

Or, you can also use the up, down ,left or right keys to move the camera around the street.
Finally, let's keep pressing the down key and see what's happening.

Future Value Interest Factor Of Annuity (FVIFA) Calculator

Future Value Interest Factor Of Annuity (FVIFA) Calculator is used to compute an annuity. An annuity is a series of equal payments at regular intervals.For example, if we pay one dollar at the start of every 5 periods with an interest rate of 5% period, we can input these two numbers into the calculator and click Send button. Then we can get a returned number 5.525631. It means that at the end of 5 periods, we will have 5.525631 dollars.

CubicPower Future Value Interest Factor (FVIF) calculator

Future Value Interest Factor (FVIF) is used to compute the future value of money. We simply need to input the interest rate and period and click Send button. Then we can see a red number on the top of the screen. This FVIF number means that one dollar over that period of time will become how much in this interest rate. If we want to calculate 10000 dollars will become how much, we simply multiply this FVIF number by 10000.

We can try it now from the CubicPower:

CubicPower online IRR (Internal Rate of Return) Calculator

CubicPower online IRR (Internal Rate of Return) Calculator is a very useful tool for different applications. By inputting cash flows of many periods, the app will compute the equivalent return rate of the whole period of time.
The first application of IRR is for the project financial planning. To balance, whether the project is worth to invest,a good IRR number is very important.
The next application is for insurance. If we want to evaluate the interest rate of an insurance plan, we can input the money we pay and the money returned from the insurance company of all periods and the press execute to get an IRR number from the CubicPower online IRR Calculator.

Openstack code study of keystone auth and catalog

Here we study the keystone functional units: auth and catalog.
The auth takes care of oauth1,password,saml2 and token.
The catalog handles kvs and sql back end drivers for the functions create/update/delete/list of the data by region, service and endpoint.

The classes and methods of auth and catalog are listed as follows:(Click the def link can see the detailed python code on the CubicPower.)

CubicPower Channel Q: Robot Math-1 plus 1 equals 2

To get the concept of number,we can map the 1 to one block. And then map the 2 to two blocks.
Therefore "1 plus 1 equals 2" means that adding one block to another block will get two blocks.

Another way is to count fingers. One finger plus one finger equals to two fingers.

Setup a WordPress LAMP Web Server on your Raspberry Pi

The Raspberry Pi is one of the most popular ARM CPU boards for makers. Although it's not as powerful as a desktop PC, but it's still able to act as a web server. Just a little bit slow. .

Once we've set up our own Wordpress site, we also have a LAMP(Linux, Apache, MySQL, PHP) stack on our board. We can put our PHP programs to collect data from the devices and store them into the local database.

There is a formal tutorial page on the Raspberry Pi web site as follows:

OpenStack Code Study: keystone-2014.1

[Mark Hsia's Blog] OpenStack Code Study: keystone-2014.1

Keystone is in charge of login and privilege control of the OpenStack.
Here we list the python class and def declarations of the Keystone. It could be easily understood, which parts of the function have done by keystone.

First, we show \keystone\assignment. Three types of back end drivers are included here: kvs, ldap and sql. They take care of creating,deleting,updating,listing the project/role/grant/user/group/domain.

Clicking the link will bring you to the python code of that function on the CubicPower.
