Every once in a while, someone makes an impression on you that lasts for a lifetime. It sticks with you every single time. This is one of those, although a bit on the nerdy side, it is one that can change the way you present information in a very meaningful way.

I was once sitting at the NIST annual fire conference, going about my business, and someone working on a project regarding the structural response aspect of buildings on fire showed a video in their presentation. No big deal, right? Normally, we get cool fire videos, then some plots, and so on. Sometimes the plots are interesting, sometimes they are default from Excel with the ugly legend and all – with no story to tell.

But not this guy. He showed a video with real-time plots superimposed over the video showing the exact real-time structural response of the structure overlaid on the video in a plot. “AMAZING!” I thought. And it stuck with me. A useful way to convey synchronous information. People love videos, why not tell the qualitative AND quantitative story at the same time?

So I started working in grad. school on fire problems, and naturally, soon thereafter, I was scheduled to give a presentation. As most of my real creative coding and writing work happens of hours between the hours of 1 AM and 6 AM, I wanted to make this happen. I REALLY wanted some real-time plotting action in my presentation. No Excel templates for me! So I stayed up for a couple nights and worked on a way to use MATLAB to make this plotting dream a reality: I worked on importing videos, messing with frame rates, tons of images, and so forth. And soon thereafter, it happened. I had a working script.

I used it to show plots of large-scale fire tests with actual and predicted flame heights vs. time as seen here:

And I used the script to show the predicted flame heights on a small-scale test in an amazing way that just about anyone can relate to, fire-crazed scientist or not:

From anyone who has seen the videos firsthand, the response has been amazing. This is a great teaching and communication tool, and surprisingly enough, I haven’t found any existing program or tool that does this. And so I am sharing the videos and script here for anyone to use to better convey information.

My next steps are: 1) to convert the script to Python (since I am now almost exclusively using Python+numpy+scipy for my graduate research and daily work instead of MATLAB, and 2) to make the script into a cross-platform and easy to use tool.

I’m providing the code in its raw and uncommented and unedited form. It generates a number of images with plots superimposed on them, and then it is trivial to use a program to stitch them together into a video. I used Quicktime’s built in method. Sorry, too much current work going on finishing my MS thesis and Master’s degree to clean up the code, but it’s a brutal use of the “release early, release often” ideal! Hopefully someone can make some use of it.

Whenever I listen to it, I am reminded of my grandfather, Jesus Gonzales, born 1908. It paraphrases something that he knew, something deep. It was to clear your mind of any toils or stress from the day that just passed you by. Jesus, or Apa, was married to Margarita Gonzales for many, many years, and he rubbed off on more people than I’ll ever know. He was one of the happiest men that I knew, in one of the happiest marriages I will ever know, ever.

He was a simple man who simply loved life. That feeling and mission I can certainly share with him. He told me to never go to bed angry, at anything. This is before computers, before we began to live in a life surrounded by computers and overwhelming days. He was never too busy for anybody, including you and me.

So I paraphrase him, as Apa wouldn’t mind, and say not to let the sun go down on your grievances. Sleep well, tell the one you love that you love them, and breathe in all the we have. Thanks Apa. I miss the days where I would go “fishing” and hunt for the raisins in my Quaker Oats oatmeal.

You knew exactly how to live life, and we all learned from you to pass it on and on.

Don’t let the sun go down own your grievances:

Don’t let the sun go down on your grievances
Respect love of the heart over lust of the flesh
Do yourself a favor: become your own savior
And don’t let the sun go down on your grievances
And when you wake up in the morning
You’ll have a brand new feeling
And you’ll find yourself healing
So don’t let the sun go down on your grievances

So, let me explain his model simply by example:

The professor said that when he first started this class 2 years ago, the students were working on a different problem with no solution… at the time. The class worked together and in the end the results were so significant that a couple of students took the initiative to publish the results in a scientific journal. The same happened when the class was taught last year – project done, paper published.

So what does this mean and why do you care? Well, all too often in the academic world, people can get caught up in working on projects and sort of work themselves into a dark corner where nobody gets to benefit from the results… and this is done in real life as well, not just academics. This is where the ridiculous amount of collaborative technology available to us comes in to play. Want to gather up notes on the Smagorinsky constant and publish them for anyone to find who is searching for them in the next 1000 years? Easy: 5 minutes. Want to publish your results in the most useful way? Easy: work on an open source project in your area along with your research – or make your own.

…Or you could write a paper, finish your thesis work, wrap up the loose ends in a few years and show a flashy poster of your work 5 years after anybody cares about it anymore or thinks it to be useful.

I digress. I just wanted to stress this new method of collaboration that is among us, and how it’s going to change the way that we work together and grow together in fire protection engineering and fire science.

[From Rowan University College of Engineering]

Why not make use of motivated students and brainpower when they come together? Here is me welcoming this new phase of community and collaboration in a field that directly impacts life safety and makes safer buildings around the world. So when we work on that final project in a few weeks, it’s not really at all about a grade anymore – it’s about a new way of doing science – together.

Update: This is exactly the kind of stuff that I’m talking about here, posted today on the SFPE National blog that I set up a year ago – collaboration: Foundation Funded Research underway at WPI

This week’s journey leads me to a Thursday night (day 2 of 3) in Caldwell, TX. I am doing fire alarm inspections for four local schools that are pretty huge and thusly I am hanging out at the Sunset Inn for 3 days. This means that I get paid to torture the summer cheerleading camps and office ladies with blaring fire alarm sirens all day long.

And just so you know, in the picture on the front page of my hotel’s (Sunset Inn’s) website, there is a huge Walmart sign right there looming in the background for your nightly dose of subliminal Caldwell advertising – it’s like a bad smell that you can’t help but keep smelling.

Caldwell TX is about 25 miles south of College Station. So everywhere I turn, I see AGGIE COUNTRY signs and all sorts of aggie references. Nothing new here, just overloaded with it. THIS IS AGGIE LAND!!!

Last night, Katie and I were hanging low with the locals at the Texan Lounge about 0.8 miles away from my hotel room. Everything was typical Texas – maybe so insanely Texan that it was just… normal. A sign on the wall said – IF YOU AIN’T OILFIELD, THEN YOU AIN’T SHIT. And I didn’t even want to ask the bartender and get shmacked in the head nor do I even want to Google it. Just let it coexist within my mind, alone and peaceful.

Now to the media: Yesterday, when inspecting the local high school’s fire alarm and deafening the occupants to their demise (and my pleasure), I came across this room (it was actually in the faculty “work room”). Hmm, my school didn’t have one of these:

Smoking bans in Houston bars, smoking rooms in high school faculty lounges, I see the real truth now.

Next up, in the bathroom reserved for only the staff and faculty to do their dirty handywork, located smack in the center of the building amongst the hallways, where surely a middle school student could take wafts of their biology teacher’s deuce:

Thanks Caldwell schools for keeping my teachers clean and freaked out by psychadelic super graphics from space!

And finally, the local schools are plastered with reminders and motivational messages from Aristotle, Einstein, and other great thinkers. But this one particularly caught my eye; they sure do want to remind us of something here.. what is it? Oh yeah!:

I can’t make this stuff up folks. I love it. This job gives me random input from all angles that I never see coming. Good pay, good travel, good summer work. And great timing! – I am definitely getting my Texas fix in before I leave this great state in 20 days.

After working until 8:30 pm tonight, I only had the energy to visit the Brookshire Brothers about 400 feet from my hotel and gather some resources for my last night here: cold beers, a TV dinner, a banana, and a bear claw for breakfast in the morn. During my checkout process, the grocery sacker told me about six and a half times how cool it would be if “you could buy beer when you were 15 years old.” He was about 2.5 times larger than me. Noted.

Thanks Caldwell. Seriously, I love your offerings, no jokes. And here’s to tomorrow. I <3 you Texas.

P.S. Thanks to Sunset Inn for making this blog post all possible with a $35 dollar room with free Wifi! Ahh America!

Well, I happen to think that it not only affects your daily pursuit of knowledge and you work in whatever field you are in, but it also greatly affects the way we work together as a society, create and bring new ideas into fruition, and nurture successful generations to follow.

Last Thursday, the FCC held a public hearing on net neutrality. 5 commissioners from the FCC joined and heard from leading public scientists, network operators, and entrepreneurs. 2 commissioners were in support of network neutrality, 2 against, and one neutral (pun intended). Also, Comcast and many other carriers were invited to the hearing; however, they declined.

Here is the video from the hearing as well as other snippets on the topic:

Jason Devitt, CEO of Skydeck, testifies at the FCC Hearing

Law Professor Lawrence Lessig on Net Neutrality and the Rise of Google

From Barack Obama’s address at Google

You’ll notice I stuck a button on the right of my site in support of net neutrality. I’ll be calling my senator and representatives on Monday morning to let them know of my support of net neutrality and a new Act working its way through the House of Representatives. I urge you to do the same. It is critical to recognize that issues such as Verizon winning the FCC spectrum auction to Microsoft’s OOXML as a international standard to Comcast breaking fundamental ethical and technical ways of the internet are of utmost importance to our current age, culture, and political era.

In the end, regardless of the specific topic at hand, be cognizant of those trying to disrupt and block the progressive movement that is before us. Especially when it involves profit rather than progress. Especially when that blocking impedes our societal learning, sharing, innovation, creativity, and global and equal access to information for all.

Along the way during the past month, I have sifted through hundreds of websites and quite a few beginner books. So here, I would like to share the links that I found most helpful in my quest for Python knowledge. As far as my past experience, I’ve dabbled in many other languages such as MATLAB, HTML, Fortran, C++, Java, Perl, and so on but never really grew to master a single one or use it in my daily life.

So, without further delay, on to the list:

Before You Start With Python

1. Python.org – I couldn’t make this list without including the main Python site. There is just a great amount of information there. Plus everything I link to can probably be found there, but my list is only those resources that really helped me along in my learning experience.
   
2. Teach Yourself Programming in Ten Years – Article by the director of research at Google – A great overview of programming and learning to program, all the while avoiding the ides presented by the “Learn to program in X days” books.

Excellent Python Tutorials

1. Dive Into Python – This is one of the first tutorials that I read about Python, and it gave me an excellent overview of the language. It really broke down the code line-by-line, but it still reads like a mix between a reference guide, a cookbook, and a tutorial. It’s a freely available book and should definitely be within quick reach as you learn Python.
2. How to Think Like a Computer Scientist – This is by far my favorite tutorial in the entire list. I like this (freely available) book because of its plentiful and challenging exercises! I am usually picky when choosing textbooks on a new subject, and I will almost always get the book that has the most examples in it. I spent most of my time creating my own programs at the end of each chapter, and really got a feel for the language (and a nice sense of accomplishment!) at the end of each chapter. Highly recommended.
3. Python Videos at ShowMeDo – There are over 100 videos at the time of this posting over a wide range of topics. Anything from how to open a Python session to namespaces and more. It was nice when starting out to just sit and watch someone who knew what they were doing do routine tasks, and it helped to ground basic concepts before jumping in on my own. Don’t forget to thank the creators of the videos with a comment!
4. Learning to Program – This is one that I am going through last, because it gets into a bit more in depth discussion about basic and moderate topics. Very thorough.
   

Beginner Exercises and Projects

1. How to Think Like a Computer Scientist – I just HAD to list this again, because it goes at just the right pace and the exercises are well thought out. I am convinced that I really learned about 80% of my Python basics here when I put them to practice. Learn by doing!
2. Projects for the Beginner – Python – This is a thread on a forum with over 100 ideas for programs. Use this when you are low on inspiration but high on ambition!
3. Python Challenge – Neat implementation of puzzles that can be solved with Python scripts. They get harder as you progress levels. You might want to hit up the Python Challenge after getting a good hold on the basics and after you have many of these other links open in other tabs.
4. Useless Python Challenges – This site should be visited after you have finished all of the trivial Python exercises and projects. When you are self-sustaining on the language and eagerly looking for some projects to do, but are hitting a writer’s block for programs, go here.

Beginner Forums and Lists

1. Python Forum – Beginners – Not a very high traffic forum, but they have a beginners subforum with 15-30 posts per day, just enough to keep you busy. I find it helpful to attack the problems that other beginners are facing. And if you come up with a good solution, post it and help others while you learn. Everyone wins!
2. Learning Python Blog – One of the few “learning only” Python blogs. It is always good to see information shared from others while they learn. Sort of like this list.
3. Python Tutor Mailing List – I only recently signed up for this, but I must say that there are some very knowledgeable and helpful people on here and it keeps the Python information coming at you via email. Seems to be quite a few students on here and you will most certainly learn something with each email thread.

Interesting Python Projects and Libraries

1. Django Project
   
2. TurboGears
3. Google GData Python API – This is an amazing API from Google that allows you to interact with Google Calendar, Docs, Maps, Youtube, Notebook, and so on. It is very easy to install and use and I look forward to developing with this in the near future.
4. wxPython – GUI toolkit for interface development. I haven’t gotten to GUIs yet, but everywhere I turn I see references to wxPython.
5. matplotlib – 2D plotting library that produces very nice looking graphs. Supports many, many types of graphs and is very customizable.
6. SciPy – A collection of Python tools and modules for use in science, engineering, and mathematics. This is the light at the end of the tunnel for me and I hope to get more involved with this library as I progress with my Python learning.

Editing Tools and Shells

1. iPython – An enhanced Python shell that seems geared towards science, engineering, and high performance computing.
2. TextMate (Mac OS X) – This is such an amazing editor that I must list it here. I didn’t use it at all before I started with Python, and now I simply cannot go without it. I had previously heard it described by programmers as a magical tool, but I had no idea. It does autocompletion based on previous words, syntax highlighting for a ton of languages, has a quick and easy-to-read method to execute Python scripts. It is perhaps the only non-free item in my list, but very much worth it!
   
3. TextWrangler (Mac OS X) – This is what I used for a couple of years… until I discovered the greatness of TextMate a few weeks ago. TextWrangler is free though if you wish to use it.

Other Resources (References, Packages, Hosting)

1. Python Library Reference – Huge list of explanations about Python’s Standard Library. Made to help you discover the power of Python in your everyday programming.
2. Python Webhosting – List of webhosts that offer Python solutions on their webhost. Python can be run on most hosts via CGI, but these wiki pages explain exactly how they implement Python usability. Plus I found out about the cool idea of HCoop cooperative web hosting through this list; this is the host on which you are reading this blog.
3. Python Package Index – Directory of Python packages that you can learn about, download, and use in your own programming. Don’t reinvent the wheel!
4. Python Cookbook Code Samples – This is a directory in the same vein as the previous listing, but the solutions to problems are presented as code with user comments. As of now there are over 2000 recipes.
5. The Daily Python URL – Just as it sounds. News about Python in compact form.

Again, while there are many, many other resources for learning Python, this is a list of my personal favorites. These are the specific sites that have been very helpful and impacting on my venture to learn Python. So while I may not have listed a particular item – I probably saw it, but didn’t get much from it at this time.

Finally, you must forgive me if I got some detail wrong. I am learning, after all! Hopefully this list will help new and moderate Python users to utilize some of the best (and free!) Python resources that others have put up for all to learn from. Thanks to those people who shared their knowledge. And have fun with Python!

So, this is nothing other than an updating type of post, a snapshot of where my neurons are firing.

1) Been actually practicing typing and using Python everyday. Did you know that the language Python was named after Monty Python’s Flying Circus? Neither did I until finally doing the official tutorial. Why am I practicing typing? I have been using computers since I was about 5, and still I cannot proper type. Sort of embarrassing. Not that though. I just want to type about thinking about typing. This post was written without proper typing. I have finally completed the typing tutor deal on my laptop. And now just need the practice part. I can type at 90+ WPM with this improper style, but the memory obstacle is still there.

That moves me on to Python. Why am I learning yet another language? Well, let me clarify. I am not the master of any one language. Python just seems so sensible to me. Good language to finally master. It comes on every Mac and Linux install. It can do all of my automation tasks that I dearly not need waste time on. Filling out FDS files based on numbers in a CSV file. Searching through PDF files for a server. Or making a post-processor for FDS output files. I love the direct-ness of the language. To print something is “print ‘hello world”. And that’s it. No braces, no output specifiers, no weird containing characters, no declarations, and so on.

2) Finished the Four-Hour Work Week. Amazing book. It is the first book that I am going to buy ever since giving away a huge percentage of my books about six months ago. I am now tasked with actually making something tangible that the rest of the world can use (and will pay for). The book is not just a business book, but a book about lifestyle, travel, and the philosophy of modern culture.

I now have to think about what I can provide to benefit masses of people. Perhaps the biggest thinking outside experiment that I have ever done. This can be difficult for my idealistic mind, but is totally possible. Since I retired in the month of August in 2006, this is certainly a key element in keeping myself financially supported – but avoiding the traps of an 80-hour per week self business. I do hope to develop my website with more FDS videos and info. This website or another, I am not sure. Hobby or “business”, I am not yet sure. Time and experiences will tell.

3) Travel. Need more travel and exploring. The above points will actually help with this in my abstract mind.

4) Graduate school politics. My fire science hero has a terrible relationship with my future grad. school advisor, department, and school. Yay. All I want is meaningful work, and I hope that they all understand that. To think that my next two years of work might be thrown away is 1000x times worse than saying I would never be paid for the work. I will do my best, as always. My future advisor posed the question of why should an entity contribute to an open-source worldwide project who did not fund them directly. Why should he post the “results” for free. This violated one of my primary values in life. I immediately thought of Linux, KDE, Google, and tons of other open source projects that were not directly funded by those agencies themselves but have benefited the lives of millions based on contributed work.

Hell, I have been contributing to the FDS project for “free” for the past three years in whatever way that I can, every single day. I would do it for free – because it is one project of many in the world that is meaningful and benefits the world. It even has the bonus of saving lives through better fire protection design. So, I took that comment with a hard heart and looked back on the past 2 years as I have been earning a McDonald’s salary to teach, research, and contribute to a meaningful project. Priorities.

To leave on a good note, as I should, I have emailed several contacts around the US and the world about future travel and research opportunities. We will see what happens! Have a fantastic week.

The first set is a small section of the King’s Cross fire which occurred in a London Underground station in 1987 and killed 31 people. The flames were said to have been traveling sideways because of the trench effect that the escalator tunnel gave way to. Many people went up a parallel escalator and were later killed in the ticketing room where the hot gases were collecting from the escalator like a chimney.

Early stages of the fire in which the wooden treads are catching from the fire underneath:

View of surface temperatures within the escalator shaft. The concrete ceiling reaches temperatures of 700 degrees Celsius after a few minutes of the fire growth stage in our model.

The gas temperature represented by different colors. The gas temperature is about 1500 degrees C after a few minutes in the model:

Two views which show 1) the velocity field within the shaft 2) the trench effect on the flames and fire spread 3) the smoke layer within the shaft 4) and the plume trajectory in the shaft

This is another model which is being used to teach a class in structural fire safety. It is an arena model and shows how readily a fire will develop in an unprotected large room with no fire protection and a large fuel load. The layout is similar to churches as well, many of which are grandfathered into the modern times and exempted from installing fire protection such as sprinklers or evacuation alert systems.

The fire spreads from a source in the corner. The smoke spreads quickly and serves as a medium to heat the roof and structural elements. The energy from the seats flows upwards and feeds the spread throughout the roof, while the radiant energy comes back down to continue the cyclic destruction of the building’s elements:

Outside view of the arena with an angle wood roof and glass atrium at the peak:

View of surface temperatures inside of the arena:

I hope that you enjoyed today’s lesson and learned something from me sharing my current progress in fire modeling for the semester. Enjoy!

Why does the modern education system do this, even at the university level? Think about it. If you submitted the above purposely-vague course description in order to have a class formed, who would approve that mess? Who would want to take that class? A class that closes your mind and limits your exposure, the opposite of what you should be doing at this time; exposing your mind to tons of different random inputs, tools, methods, and opportunities in the world.

Furthermore, instead of learning how to adapt and use existing solutions and integrate them into your wonderful tool pouch, the students distantly type up examples from a non-existent space in a book and go home for the week. Going home and never again caring or wondering how technological tools can help them and challenge them to the point that it will change the way that they work, think, and solve problems.

When I worked in the summer of 2007 at a research firm in Maryland, I got to use any tool that I wished to solve an endless number of problems (my dream environment), as long as the results could be effectively communicated, shared, and built upon by all other participants in the problem. Of course, I had to use MS Word and Excel a couple of times, but I did not let that limit me. I must have gone through using over 50 different applications, many times on just a single problem. I used MATLAB, R, FORTRAN, Google Docs, Perl, Python, PHP, TextWrangler, SigmaPlot, OpenOffice, NeoOffice, Linux, Mac OS X, GMail, Gimp, Photoshop, Illustrator, Applescript, shell scripts, Google Video, Google Code, Google Apps, Google Groups, CyberDuck, SmartFTP, SmartSVN, TeXShop, and tons of other tools, many of which were free and open source.

And that is not to say that I am an expert in any or all of those applications, but that I have the engineering ability (I use this in the traditional and broad lifelong sense of the word) to be able to know when to use a certain tool, how to fit it to my needs, and how to use it efficiently. Being able to pick up any tool for a job from cold and cater it to your needs is certainly a skill that will separate you from 90% of your peers in school, work, life, relationships, and personal progression.

That being said, how does one teach this skill to a class of engineering students who may or may not know that they want or need this dexterity and competence? Well, how does one learn the skill in the first place? I think that when a problem arises, any problem at all be it an assignment, a task, or a hobby, one starts to look for answers in places that he or she is formerly comfortable with. This usually means that they miss out on a well-structured Google search where the answer would have been right in front of them in this collaborative world, waiting for them to use it and mold it to their needs. But the students continue on, not aware of the opportunity and challenges that are waiting to enrich their daily lives.

“How do I insert the footer here?” “How do I log into the wireless?” “What formula will show today’s date?” Please, for the love of all that is spinal, use the help file, use Google, use your minds in this environment that is not only openly and excitedly available to you, but that you are paying about 500 dollars to be purposely surrounded by! If most of the time is spent adjusting margins and Excel specific commands and headers and print previews, where will the guts of learning and inspiration come from? I do not mean for this to be a generic rant, but rather a resounding and powerful call to these types of courses and professors to turn around and challenge the intellect of the student in solving problems and furthering their thinking capacity in life. Anyone can achieve this if they try and are provoked in just the right way that stimulates that certain passionate part of their mind.

For instance, consider a slightly disorganized and unformatted spreadsheet that effectively and elegantly solves a problem in which the student spent 3 hours on the solution and 5 minutes on the design. I would much like to see this sort of result and output rather than a spread of pretty colors and fonts that only serves to find the area of a circle – go and solve something real. Come on mentors, teachers, and those in charge of challenging us as humans: summon our great and collective minds!
