Agile and Scrum Master Certifications

Agile and Scrum Master Certifications
(For those of you not familiar with agile, you might want to read this first or look up Agile in Wikipedia)
From my research, I've found that there are 3 popular Agile certifications:
  1. PMI ACP : Agile Certified Practitioner offered by Project Management Institute
  2. Certified Scrum Master - offered by the Scrum Aliance
  3. Professional Scrum Master - Offered by Scrum.org
There are others too, but from what I see, these are the ones that are most popular.
I have used various Agile frameworks/methods for many years, but haven't been certified. I did receive an Agile Practitioner badge as a result of spending many hours in 3 comprehensive IBM Agile courses. I really learned a lot from them. I wanted to go further in Agile training.
I was trying to decide which path to take, so I read the information at the following sites:
After reading them all, I decided to go for the PSM first. I do put a lot of value on the ACP, but I saw lots of job postings asking for agile and scrum and thought that going for the PSM might be the best one to start with. 

I found the following links that I have been using to study for the test:
  • Suggested Reading for Professional Scrum Master™ - This page suggests where to get the Scrum Guide, books, videos, courses and more for training. The Scrum guide is important to know and the Scrum Open Assessment can be taken many times.
  • Scrum Training Series - These free video courses are great. There is a test of several questions at the end of each lesson which have references to reference material to let you know why the answer is the correct answer. This aids me in learning.  There are also links to documents and videos that I found helpful.
I'll come back here to update this as I progress in studying. 
If you have any thoughts on the certifications, the path, or any questions, please comment. I would like your input.

Fun Party Game: Hunnert

A friend told us about this game recently and sent me these directions. We played it yesterday at the family reunion. We had children and adults playing it together. The youngest child kept asking to play again and again even though others won! Children can play as long as they know how to write their numbers up to 100.  The game is supposedly called "Hunnert" as a quick way of saying "hundred."


Place on the table one pencil and one die.

Give each player a blank piece of typing paper to place in front of them

The first player rolls the die toward the next player in a clockwise fashion

If the number rolled is a one, three, four or five - nothing happens and the next player rolls the die toward the person on their left

If the number rolled is a two, all players pass the paper in front of them to the person on their left

If the number rolled is a six, the player who rolled the die grabs the pencil from whoever currently has it and begins writing numbers from 1 - 100 on the piece of paper in front of them. They continue writing as rapidly as possible (and do not take any more turns rolling the die) until either someone else rolls and six and takes control of the pencil (and begins writing numbers on their own paper) or until they write numbers all the way to 100.

Whoever writes the number 100 on their paper is the winner.

Note: if someone has the pencil and a two is rolled, they will get the paper from the person on their right, so they will start writing numbers starting at whatever number comes next after whatever number was last written on that paper. 

Try it and comment here if you found it fun. Also, post here a comment with any fun games you like to play.

Save Yourself from a "Trip" to the Hospital


Save Yourself from taking a "Trip" to the Hospital!

I used to go to a barber in the next town. He retired, so I haven't seen him for a few years. He was a veteran. He told me many stories. One was about his wife. She fell down the stairs at his house once a few years back. She has suffered since then with injuries.
   Once we had a safety expert at work. He said that when something "almost" happens or when someone has a minor trip-up or accident, we need to heed that as a warning.
   I keep thinking about the barber's wife. I've made sure our railing is always tight.  Whenever I see how dark our stairs are at night, I think about articles I've read about people needing to be careful for safety in their homes and how we need to be careful about lighting. I've been thinking about using some electronics to make a light that senses movement and turns on.
Then I saw this at home Depot for about $13 for two (only one shown in photo).
We put them on our stairs. They work pretty good. There are other similar ones. I put one in the garage too. That one is mounted on the ceiling and lights up most of the garage.
So, here's a suggestion to save you from tripping on the stairs (or your garage or anyplace else) and taking a trip to the hospital. Think about getting something like this.
All the best to you!
I'd like to hear your thoughts on this suggestion. Please comment.

Things I've worked on in the past

Here's a list of things I've worked on in the past.
I'll add to this as I remember them and have time to add to it.

In college, my senior project was a spoken word recognizer. It was supposed to recognize spoken words for each of ten numbers: zero through 9. It didn't work. It was programmed on an Altair 8800
(another post about the Altair 8800 computer). The professor who taught the class was the only one who could pull the paper tape through the paper tape reader (it was pulled manually) without getting an error.

Used punchcards for a fortran class

I then found out that if I asked a teaching assistant for a class, I could be able to work on a teletype
https://en.wikipedia.org/wiki/Teletype_Model_33
When he had the class with me (a one-on-one) it malfunctioned and paper started shooting out the back!  Years later, when I was working in the "real world" I bought one from the local Morris County College when they were getting rid of them. I used it with compuserve (an early online community before the internet and facebook). The whole house shook when I used it!  It had an acoustic coupler that was used over the phone line.

At home, I worked on hobby computers
While in college, I bought an 8080 kit. I never had a chance to build it, because I quickly sold it to buy a Kim-1 computer and started a company to sell software for it
http://oldcomputers.net/kim1.html
I traded it in for a RCA VIP
http://oldcomputers.net/rca-cosmac-vip.html
And then later for an Atari 400 and then traded that for an Atari 800 (which I still have)

Later I bought an IBM PC compatible computer which costed in excess of $1500 - I have never bought a computer as expensive of that since then!

At work, I was developing microprocessor based solutions for a military subcontractor called Conrac (later Smith industries) for the F/A-18 fighter/attack jet and the AV8B Harrier Jump-Jet on a very large intel development system (one of the following, but I'm not certain which one:  MDS-80, or MDS-800) for the intel 8080 microprocessor. At the time I had either the RCA-VIP, or the Atari 400 or 800 and would tell folks at work that while I was taking months to develop programming code for these microprocessors at work, I had more powerful computers at home!

At one point, while out at a local computer store looking at some add-on parts, I saw an advertisement to work for a company. I interviewed and got the job to work on video games for the Atari VCS: http://oldcomputers.net/atari-vcs.html
(see my video games page for more info about the games I worked on)

While there, I worked on toys too, like games for the Etch-a-Sketch Animator 2000. Colleagues of mine worked on the Fisher-Price PXL2000 video camera for children and the video camera inside the Lionel Train - I think called "Railscope")

I worked on a multiyear research project for a Vettest Veterinarian Blood Chemistry Analyzer (which is still being used in 2017 and is a 3.2 Billion dollar product family) for which I was awarded 3 patents (see my patent page for more info about patents I have).


I left there to work for a company where we made even more video games (see my "video games" page for more about that)

I'll try to add more to this later.

TJBot New Recipe (post #5 about TJBot)

TJBot has learned some new tricks!
 
I loaded a new recipe to show to the Children at the Vacation Bible School (VBS) at Church a few weeks ago! The Children and parents liked meeting TJBot!

 This is all mostly technical stuff for people who ask me questions about how I did it, so if you're not technically minded, you can skip this blog post.

 First, here are the links to previous posts on TJBot:  #1 order parts,  #2 test the hardware, #3 assemble the cardboard , #4 TJBot Talks


One thing I missed in the assembly instructions:
Use a screw to connect the TJBot Arm to the servo, otherwise it will keep falling off! (not mentioned in any of the instructions anywhere)





So, here are a bunch of my notes I took. They are sporadic because I stumbled on them over the course of trying to get this to work. 

I loaded a new recipe:
Recipe for TJdashboard - https://github.com/victordibia/tjdashboard
  
After done loading it, you can retrain Conversation to add more intents. I did this and added a bunch of intents and dialog entries to correspond to the Bible topics of the VBS week.
May need to get a new trial account since there is a limit to the number of services.
 
Booting up TJBot without a monitor and keyboard
I couldn't get auto boot up to work (see links below), so needed to ssh from laptop to get TJBot started, so used these instructions
https://www.raspberrypi.org/blog/use-your-desktop-or-laptop-screen-and-keyboard-with-your-pi/
those instructions are very complicated, so basically I just did the following:
Connect up a cable
arp -a
ssh pi@raspberrypi.local
Then, once connected, modify the wpa_supplicant.conf file for adding new wireless SSIDs and pwds
https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md
http://weworkweplay.com/play/automatically-connect-a-raspberry-pi-to-a-wifi-network/
do ifconfig to get IP address (see below), then Then to start TJbot Dashboard:
cd /home/pi/tjdashboard 
and 
sudo node dasshboard.js

Control-C will stop the dashboard program from running on tjbot.  You should do sudo shutdown to gracefully shut down the pi

To select the correct microphone
arecord -l
sudo config.js
modify it for the correct device ID
(can also flip the camera there too)

you may also need to Blacklist audio
https://github.com/ibmtjbot/tjbot/tree/master/recipes/speech_to_text#troubleshoot


to get to the "dashboard" from a browser...
ifconfig to get ip
http://192.168.1.2:8078/
 
Dashboard buttons: 
"See" will take a photo and tell what it sees
Text will take a photo and look for text in the picture that tells a color 
Dance: will dance and wave arm
Wave: will wave arm
LED: to change LED color


Turn "Listening" on and off then it will not respond

Faces: uses local Face detect and will load your picture in dashboard
Sentiment: only if you connect sentiment 

Note that Everything you say is sent to Watson Conversation Service (WCS), but only acted on if an intent is found

Here are some posts I used to try to boot into the dashboard at startup, but I can't get it to work
http://www.instructables.com/id/Nodejs-App-As-a-RPI-Service-boot-at-Startup/
https://raspberrypi.stackexchange.com/questions/44957/running-node-js-with-forever
http://www.linuxcircle.com/2013/12/30/run-nodejs-server-on-boot-with-forever-on-raspberry-pi/
Tried the comment at the beginingof /etc/rc.local:
node /home/pi/tjdashboard/dashboard.js < /dev/null &
It started up, but can't reach the dashboard URL without getting errors
