Hugo CMS & Dreamhost: Build and Deploy Niche Websites Easily
I recently abandoned WordPress (again) for Hugo CMS on Dreamhost. This is the simplest and cheapest solution I’ve found for deploying Hugo CMS based sites on a reliable and affordable host. I’ve been a user of Dreamhost for over 15 years and here’s how I hyperscale Hugo CMS based niche websites and Dreamhost for profit.

Boost Passive Income with Hugo CMS
This short post is just a way to get my thoughts down on “paper” about using Hugo to hyper-scale niche websites. I’ve been researching niche websites and their ability to capture niche traffic to generate passive income. Yes, the name of the game is to build up a net monthly passive income of around $10,000.
To get to that level of income I need to find a niche topic that will allow me to capture long-tail keyword traffic, then monetize each page, and optimize SEO.

FB Prophet Forecasting
This tutorial will show you how many followers you should expect in the coming days and weeks using the Facebook Prophet (FBProphet) python package. This is a perfect example of what python can be used for. You can use it to forecast your medium followers or sales revenues. It can be any time series related problem, but first you must install FBProphet.

Open Source Exploitation
Here’s what I say, feel free to fork it. Feel free to build whatever “consortium” you want, but it’s going to be a futile effort. You won’t be able to use the original name in your forked product or service, so you won’t get brand recognition.

You Are An Expendable Organic Robot
Massive tornadoes ripped through a big portion of the Heartland a few days ago. The fact that we’re having tornadoes in December is for another post altogether but the travesty in all this is the needless deaths of workers that weren’t allowed to protect themselves.
Despite the advance notice by weather forecasters about the impending dangerous weather, many owners kept their employees working.
Over 76 people are confirmed killed that night, an estimated 70 alone in Kentucky with a majority of the dead coming from a candle company owned by Mayfield Consumer Products.

Python to the Rescue
I’m evaluating whether or not I should move this blog to another CMS platform so I can start building a community around it like it was before.
Right now this blog runs on Hugo and AWS Amplify and it’s freaking awesome. I push new posts to GitHub, AWS pulls the changes and rebuilds the site, and then I can look at make sure it looks fine before I merge into master.

Restarting the Site
I shut Neural Market Trends down on the last day of August thinking it was going to be for good. Things have changed on my end and I’m thinking of restarting this site. I’m thinking of moving back to my roots and building a community.

Kubernetes & Julia Language
I’m coming up on my 3rd anniversary at H2O.ai and we’ve embarked on an interesting pivot of sorts. Our new product is based on Kubernetes. At first I thought Kubernetes is just another buzz word and a way for the Cloud providers to extract more money from users, but I’ve come to realize that it’s not.
Of course, there are pros and cons with Kuberentes, it’s new and isn’t widely adopted by organizations as of yet, but it’s neat from a container isolation and scalablity standpoint.

Automation and Universal Basic Income
There was a big news sensation about Burger King workers quitting en masse in Lincoln, Nebraska.
All 11 Burger King employees quit because:
“We became essential,” Johnson said. “And then we weren’t treated essential by upper management.”
From what was reported, they had to endure 8-hour shifts without breaks in very hot conditions. One employee was even hospitalized for dehydration, and then was called a ‘baby’ by management. WTF.
The funny thing is that we hear the standard empty motivational tripe that you’re so essential, and you’re so valuable to us.

Passive Income Update
I’ve stopped posting about my various investments that I use to generate passive income because no one cares. Sure they want to find out some ideas but there’s plenty of ideas to glean from StockTwits or Reddit forums. Right now everyone is focused on the meme stocks like $BB or $GME, but those are flashes in the pan. Just the normal noise in the market every day.
I’m doing pretty damn great for 2021.

The Meme Stocks GME, AMC, and BB
I’m still in awe watching retail traders en masse push these stocks to highs or even new highs. It all started with Gamestock (GME) a few months ago and I was lucky enough to ride the wave for two days and GTFO. My wife wanted a piece of the action, despite my warnings, and bought a few shares at $350. It went to $500 in pre-market trading the next day and then promptly collapsed.

One Year of SEO Optimization
In April 2020 my blog was barely alive. I had moved to Hugo from Pelican and ignored any kind of SEO optimization for it. I thought it was stupid and that the best content would win.

Passive Income - T Dividends
There are many reasons why I hold AT&T ($T) for my passive income goals. The first one is that it was around during the Great Depression and the second, it will probably be around during the next Great Depression. I can be pretty sure that AT&T will weather the storm if another future event like the Great Depression strikes the markets.
Sure, all the stocks will drop in price, including the ones with dividends, but think of those skyrocketing dividend yields!

Is 20booksto50k the right solution?
I’m done with my Medium vs Adsense experiment here. This is all part of a passive income strategy evaluation game I’m playing. I’m trying to see if I can build a $100,000 a year passive income portfolio. I know it will take time but I like playing these kind of games.
Right now I’m evaluating a mix of different things such as dividend-producing stocks, web monetization, and Adsense. So far for February, Adsense is beating the pants off my Medium income.

Install H2O's Wave on AWS Lightsail or EC2
I recently set had to set up H2O’s Wave Server on AWS Lightsail and build a simple Wave App as a Proof of Concept.
If you’ve never heard of H2O Wave then your been missing out on a new cool app development framework. We use it at H2O to build AI-based apps and you can too, or use it for all other kinds of interactive applications. It’s like Django or Streamlit, but better and faster to build and deploy.

Installing Ghost CMS on AWS Lightsail
This tutorial is not about porting Hugo posts to the Ghost format but instead it’s about how I got a custom domain, CDN, and removed the :80 port from a new Ghost install.
First off, setting up the machine on AWS Lightsail is pretty easy. It was as simple as selecting the Ghost install and taking the cheapest instance possible. I think the cost is like $3.50 a month, which is pretty sweet IMHO.

Passive Income for February 2021
This is my second monthly report on how my passive income journey to $100,000 a year is working. This month my passive income was a lot lower. QYLD didn’t have a dividend payout and RYLD’s payout is happening tomorrow.
However, my Adsense experiment and Medium produced the most non-dividend income. The downside was that it wasn’t enough to exceed last month’s total income. Overall, I expect there to be blips and bumps along this $100,000 journey and that’s ok.

Passive Income - JNJ Dividends
Today is the day I want to write about Johnson and Johnson ($JNJ) and why I’m holding it for the long term. One, it’s a well-established company that cranks out great products that everyone uses, and two it has amazing dividends. For each share of JNJ, you get $4.04 of dividends per year. JNJ hits all the sweet spots for building my $100,000 a year passive income portfolio. Let’s dig a bit deeper as to why.

5 Tips to Building a Dividend Passive Income Portfolio

As I’ve written before, this idea came to me after my wife and I reviewed her 401k at the end of 2020. She had by accident generated a large sum of dividends without even trying. This was the same for me in my 401k as well and we generated $800 in dividends by accident in our trading account.

Gamestop ($GME) has been in the news a lot lately and I’ve written three articles about it on Medium. It’s been an amazing thing to watch, the short squeeze that took short-seller Melvin Capital down (allegedly) and how crazy the r/WallStreetBets group is.

Passive Income - RYLD Dividends
I continue to collect dividend producing stocks and ETFs on my journey to generate $100,000 a year in Passive Income. Earlier this month I picked up $RYLD, another covered call writing ETF that invests primarily in the Russell 2000. This one has a higher Beta though, so I’m taking on more risk but I’ve kept my initial purchase small.
Stock Price RYLD is trading at its all-time highs. Everyone is thinking the Bull Market is getting a bit long in the tooth and are starting to wonder when the Biden bump will fade away.

Passive Income - QYLD Dividends
My quest continues to earn $100,000 passive income in a year. Supporting my strategy is $QYLD, a monthly dividend producing ETF that uses a Covered Call strategy by owning and selling Nasdaq 100 stocks. It’s not one for the faint of heart, but it fits with my passive income strategy and I went long.
There are two things that jump out at me risk wise.
For my readers, I’ve written covered calls before, and they’re a great strategy to amp up your returns.

Passive Income - GILT Dividends

Albeit it is a short dividend history.
I’ve written that my goal is to build up a passive income portfolio. My measure of success will be when I generate a $100,000 a year income, and right now GILT is part of that strategy.

DIY Passive Income
I spent the first week of 2021 reacquainting myself with Dividend Reinvesting and I’ve concluded that it makes a ton of sense for someone like me. Retirement isn’t here yet but I can see it coming on the horizon. I’d need to think about stabilizing my investments against volatility and start thinking of long term income.
When I first started investing I put a small amount of money in Dividend Reinvestment Plans (still long INTC, thank you very much) and focused on growth inside my retirement accounts.

2020 AI Market in Review
2020! What a crazy year! We had the Covid19 pandemic, major economic shocks, two big IPO’s in the immediate ‘AI’ space, and lots of new machine learning libraries and innovation.

Marriott vs Hilton Hotels
I travel a lot for work, or rather I used to until Covid19 hit. My last work related trip was to Florida to a convention on Robotic Process Automation (RPA). I stayed in a beautiful Hilton Hotel near a marina with a great resturant and bar. I’ve been a long time Hilton Honors member and use the AMEX credit card a lot to gain points, status, and rewards.
My Hilton Honors came in handy when my family and I were stranded overnight in Miami because flights were cancelled due to a nasty storm.

Terra Tech - TRTC
I invested in Terra Tech Corp (TRTC) back in January 2018. Marijuana / Cannabis type stocks were making big moves back then and this company looked like it would capitalize on it. At the time it was trading around the $4 to $5 range and I picked up 200+ shares of it for about $4.82.
Since then I watched it do a reverse stock split and get put on the Pink Sheets.

Facebook & Political Ads Targeting

At a minimum, this question SHOULD be asked and it SHOULD be answered to everyone’s satisfaction. Facebook, IMHO has become a tool for propoganda and manipulation.

Migrate away from Wordpress to Hugo
I’m no stranger to trying different CMS’s to see which one works best in terms of functionality, speed, and ease of SEO use. Over time - and many mistakes later - I’ve found that Hugo is the best for all three of those criteria. It’s very functional, fast to build, and easy to tweak for SEO. When you couple that together with the AWS backbone, you get a fast loading website where all the static builds happen automatically as soon as you update your Github repository.

It's a Good Time to Start a Business
I was once told that the best time to start a business is in a recession. The reasoning behind it is that the business would get stronger once the recession is over. Essentially you’re starting at the bottom and can only go up from there.
From my experience, this is true.
I’ve started several businesses over my life and have closed several businesses too. Some were better than others too. I (we) still have our real estate business but it’s morphed more from a real estate investing business to a holding company.

It’s a shame but my nostalgia doesn’t pay the bills for them and they have a lot of debt to pay back. When I think about it, why is that we operate on such an insane debt model?

Not Sure Where the Market is Going?
I don’t know where the market is going. Will it shrug off all this Covid19 pandemic or will it fall apart? I really don’t know.
That’s the thing with the Markets, you can try to build all these decision support systems to predict if the market is going to go up or down, but that always remains such a futile effort.
The only thing you can really do is protect yourself in down times and invest smartly for the long term.

Winc.com Wine Review
Two years ago we moved to a new house in a very active social community. We were going to dinner parties at least once a month and my wife would usually bring a small dish and I would bring wine.

My new gig keeps me very busy and on the road, so the last thing I want to do run around looking for a good wine.

Oil below Zero Dollars a barrel
The Oil markets are a really dumpster fire these days. With the Russian and Saudi oil wars going on the result has been a flood of oil in the markets. Prices collapsed for the May 2020 contract to -$37.63 a barrel. That’s nuts.
I’m starting to see prices being pushed down at gas stations too. Since Covid19 put a damper of travel, I think well see sub $10 a barrel oil coming.

Software is eating the World
I started playing bass guitar when I was in high school. The whole goal was to make our own music and get ‘chicks.’ I won’t lie, I was a horny teenager.

We recorded, played live gigs in New York City - even played at CBGB’s twice - and built up a small DIY following.

AI is Evolving
I posted about AutoML-zero in my newsletter a few weeks ago. I found genetic programming and applying evolutionary search for machine learning to be really powerful. Here’s another article referencing AutoML-zero and briefly talks about how AI is evolving with these approaches.
The program discovers algorithms using a loose approximation of evolution. It starts by creating a population of 100 candidate algorithms by randomly combining mathematical operations. It then tests them on a simple task, such as an image recognition problem where it has to decide whether a picture shows a cat or a truck.

The markets have been in a complete freefall over the past few weeks. The likely culprit is Trump’s mishandling of the Covid-19 (aka Coronavirus) response and overinflated prices. Who knows what is the real market contagion here but I think it’s time to make a shopping list.
With free falls in some of my favorite holdings (MSFT and AAPL), I can’t but help think it might be time to add to these long term holdings and buy more stuff like ETF’s and Mutual Funds.

Forex Trading Python Tutorial for Beginners
I have had some time to continue on my Python Forex Trading Bot (code borrowed from here and tweaked by me) now that we’re all self isolating. This is purely for educational purposes because when I run this sucker, it loses money. Not so much anymore but it’s not profitable. The reason why I say ’educational purposes’ is that coding is not my first choice of career and I teach myself as I go along.

Groovy over Python?
After a few frustrating events where I had some python code blow up because of dependencies, I started looking hard a using Groovy going forward.
For some simple things, Groovy and Python are very easy. For example if I wanted to read the latest sales from Park.IO and print them out, I could do the following in Python on my Mac.
import pandas as pd df = pd.read_csv('https://park.io/orders/export.csv') print (df) If I tried that on my old Raspberry Pi, I’d run into dependency issues w.

Groovy for Data Science
I was looking through Reddit the other day and came across an interesting post in r/Groovy. The group itself has been relatively dead for a while but sprang to life with a question about using Groovy for Data Science. Granted, Python IS eating the world right now for Data Science with R right behind it and Java still hanging out with all the Big Data stuff.
I’ve always liked Groovy because it’s very Python like (high level-ish) but compiles down to byte-code during runtime.

The Contrarian Case for Getting Active
Right before the New Year I posted an article on Medium titled “Is Passive Investing Going to Kill Us?” It centers around one particular chart where the amount of money flowing into passive investing is staggering.
While I’m a big fan of Passive Investing and I’ve been riding its success, I can’t help but wonder if I was just plain lucky. I know that markets love to correct imbalances but the question is when?

Working on 2020
Happy New Year readers! Granted it’s already 10 days into the new year but I’ve been having a well deserved break and easing back into work. Now that 2020 is here I hope to amp up more of what I did last year. Read more books, go to the Dojo/exercise more, and make more adventures with the family. I’m not really into the ’new year resolutions’ because I like to ease into things, not make abrupt cold turkey changes.

Morgan Stanley Layoffs, VTI keeps climbing
Yesterday Morgan Stanley announced a 2% reduction in workforce across the entire organization. It’s citing an “uncertain global environment.” That’s a code word for “recession” if you ask me.
The job cuts at the investment bank, the world’s biggest equities trading firm and a leading mergers advisor, will hit technology and operations roles hardest, said the people, who declined to be named. New York-based Morgan Stanley had 60,532 employees as of Sept.

How to Recognize AI Snakeoil
My colleague posted an interesting Princeton presentation to our group Slack channel. It’s about how AI is being used in social interactions such as hiring decisions. I completely get why HR departments and companies want to do this. They get 100’s of resumes from people and want to weed through the lot of them to get to the right candidates. This is how AI can help, optimizing processes to assist people to make the right decisions.

Go Master Quits, AI too powerful
I just read that Lee Sedol is retiring from the competitive Go world because of AlphaGo.
The South Korean said he had decided to retire after realizing: "I’m not at the top even if I become the number one."
This is a bit sad but understandable. I wrote about Lee’s historic match with AlphaGo a while ago. He ended up losing four matches out of five, which was an ass-kicking for the #1 Go player in the world.

AI Trading & Lehman Brothers?
WOW! I posted this over 12 years ago. Talk about being spot on the money! I hate to do this but I’m going to quote myself here:
I firmly believe that data mining, AI, and machine learning trading will accelerate over the years. Who knows, maybe my little model will move markets one day! :)
As far as the trend in AI goes, it’s really getting started now. AI is being adopted by the next tier of companies.

Investing in the S&P500 beats AI Trading
I forgot to link to this image back in early May 2019. It’s from Bloomberg and it makes a lot of sense, maybe eye opening for some.
Essentially it shows that the market is the be and end all. Of course the market is an average and there are funds or AI traders that beat the average, but others will underperform the average. Over time, your little ’edge’ will eventually underperform and you have to keep writing new code and new strategies.

Market Trends
Identifying stock market trends is like eating and drinking the Zeitgeist. It has to be inside you to understand it. You have to be social, go outside, go to parties, etc. If you’re not “hip” then you’ll never see emerging trends until they’re already established. Then it’s a matter of chasing their coattails and riding them for a bit.
Years ago Howie had a great tag-line for his blog, it was “Trends… Find them, ride them and get off.

Downloading SEC.GOV data
I’ve finally found a way to download SEC.GOV data in a consistent and less stressful way. I want to give the University of Notre Dame Software Repository for Accounting and Finance a shout out for their excellent work. Thanks to them I can finally start taming this beast.
I’ve struggled for years trying to figure out how to download SEC data. That repository is so wacky that it’s hard to find filings in there.

Managing Your Time with Stoicism
Lately I’ve been reading Seneca as part of my exploration of Stoicism. There’s a lot of great things here and I recommend you check out the video and my notes below:
To live well we must be constant students of life Seneca’s essay “On the shortness of life” reminds us that time is a non-renewable resource Treat time as a commodity, people guard their property but squander time The amount of time we get is uncertain, you could die at 20 or 100 Death creeps up on time wasters Make the most of time, it is an amplifier when used properly Don’t invest your time preparing for life Seneca pushes us to live right now and not to delay happiness Your typical life is work till 60 and then wait to be happy What usually happens is your old to enjoy life then and regret not making most of life Planning the big things in life but don’t delay living it Live life for your own self Being busy with things we don’t like is the greatest distraction of your life We waste time at jobs we don’t like, relationships we’re not happy in, etc Invest your time into making a life worth living Practice Premeditatio Malorum While you waste your time by procrastinating, life goes on Researchers call the dissonance of “short-term gratification vs long-term commitments” as time inconsistency To fight this, use Premeditatio Malorum which is a form of negative visualization Think of what could go wrong with your long term task and then make plans to achieve it.

Auto Support Resistance Lines in Forex
On the heels of my last post, I’ve extended those functions to the EURUSD pair. The data starts from this year 2019 and goes through to yesterday. It’s actually a pretty neat script as it takes data from Onada and then generates the support and resistance lines for that particular pair. The next step would be to create a buy/sell order in the Oanda Practice Account. Once I do that it’s then a matter of writing a trading strategy and testing it in real time.

Isolation Forests in H2O.ai
A new feature has been added to H2O-3 open source, isolation forests. I’ve always been a fan of understanding outliers and love using One Class SVM’s as a method, but the isolation forests appear to be better in finding outliers, in most cases.
From the H2O.ai blog:
There are multiple approaches to an unsupervised anomaly detection problem that try to exploit the differences between the properties of common and unique observations.

How Blogging Led to My Personal Growth
It’s hard to believe that I’ve been blogging now for over 12 years. I’ve written 100’s of posts, some short and some long.

Always Be Learning
I always need to be learning. If I’m not pushing myself out of my comfort zone or just plain learning ‘cool shit,’ I just get bored and cranky. This is one of the reasons why I love working at H2O.ai because I’m pushed everyday. Just this past week I was pushed into learning more deeply NLP and coding Python, two topics I’m very interested in. Along the way I’ve learn how to use Git better and solve some interesting use cases.

Real Estate Buying Guide
I want to share my experiences as a Real Estate Investor (REI) and expert in the engineering field as a way to help novice real estate buyers. My wife and I made a lot of mistakes when we started buying properties. Now, after a few years we’ve gotten it down and are ruthless when evaluating a property. We’ve bought a house from auction, written short sales documents for banks, bird dogged, and researched flood prone properties as a way to get smarter about being real estate investors.

That’s interesting news because of my personal history with RE. I have been a real estate investor that wanted to be a flipper but got caught in 2007 slowdown.

Passive Investing & Income
I’ve written about this countless times but I’m a big fan of passive investing in the markets. By doing less, I actually gain a lot more in returns. That’s all great and wonderful but currently it’s not ideal for me. What I really want to do is turn that passive investing into passive income.
So even in their golden years, they have to budget carefully.

Interpreting Machine Learning Models
I found this short 8 minute video from H2O World about Machine Learning Interpretability (MLI). It’s given by Patrick Hall, the lead for building these capabilities in Driverless AI.
My notes from the video are below:
ML as an opaque black box is no longer the case Cracking the black box with LIME and Shapley Values Shapley Values won the Nobel Prize in Economics in 2012 After Driverless AI model runs, a dashboard is created Shows the complex feature engineered and the original features Global Shapley Values is like Feature Importance and includes negative and positive contributions Quickly identify what are the important features in the dataset Then go to Partial Dependence Plots, which are the average prediction of the model across different values of the feature Row by Row analysis of each feature can be done to understand interactions and generate reason codes Shapley is accurate for feature contribution, LIME is an approximation Done via stacked ensemble model Can be deployed via Python Scoring pipeline

Microsoft the AI Powerhouse
I’ve been a long term shareholder of MSFT and I’ve been rewarded quite well. Under the leadership of CEO Nadella, Microsoft has become and AI powerhouse, and I believe he’ll win the cloud computing wars. Right now Amazon is the dominant player but based on what I see in Azure’s development, I think both companies will be ’neck to neck’ in a few short years.
Investors have rewarded the stock with new highs and crossing (before retracing just below) a $1 Trillion dollar valuation.

The Pyschology of Writing
I found this interesting article on Pocket about writing. The gist of it is that successful writing is about rituals. Every writer is different and the rituals are different, it’s all about finding out what works best for you.
Location and physical environment also play a role in maintaining a sustained and productive workflow. Bob Dylan, for instance, extolled the virtues of being able to “put yourself in an environment where you can completely accept all the unconscious stuff that comes to you from your inner workings of your mind.

The r/investing sub cracks me up sometimes. This guy has had enough of the sub because all it spews is how great Buffet is and dollar cost averaging.

Functional Programming in Python
I’m spending time trying to understand the differences between writing classes and functions in Python. Which one is better and why? From what I’m gathering, a lot of people are tired of writing classes in general. Classes are used in Object Oriented Programming (OOP) and some python coders hate it because it’s writing too many lines of code when only a few really matter. So programmers like functional programming (FP) in python instead.

Makers vs Takers
The best startups have a ‘Do It Yourself’ attitude. When a problem arises, no one get’s assigned the task to solve it. The team jumps right in and gets to work. There’s always a sense of ownership and a sense of pride. They build new things because it’s cool. They think of ways to make things better and make it happen. They are the ‘Makers’, and for lack of a better word, they make $hit happen.

The Westport, Connecticut-based firm is the world’s biggest hedge fund with about $160 billion in assets. The gains for its Pure Alpha Strategy came as other fund managers were whipsawed by volatile markets, resulting in the industry posting one of its worst years ever.

Living the Dream?
I’m going to preface this post by saying that lately I’ve been pretty emotional. I’m not sure why, but perhaps it has to do with the fact that in a few short years I’ll be a half century old. I’m starting to look around me and catch glimpses of my mortality in the rear view mirror. Oddly, it seems to be gaining on me every time I look.
For those that know me, I have a favorite saying. When I’m asked “how’re you doing?” I reply, “I’m living the dream.” Sometimes I get a chuckle, sometimes I get a sigh, and sometimes I get “Yah right, more like a nightmare.”
I’ve come to find that I can learn a lot about a person by how they answer this question.

Humility and Equanimity in Sales
Dear Friend,
I’ve been meaning to write about the importance humility and equanimity in sales. From my personal past observations, it seems these are attributes only a few sales people have.
What is humility and equanimity?
Humility is defined as:
“a modest or low view of one’s own importance; humbleness.”
Equanimity is defined as:
“mental calmness, composure, and evenness of temper, especially in a difficult situation.”

What is Reusable Holdout?
Overfitting and introducing bias during model training is always a big topic in data science. Typically you train a model using Cross Validation by creating a model on k-1 folds and test it on the remaining one fold. This one fold is the holdout set and will usually work very well if, and only if, the trained model is independent of the holdout set. Under normal situations, this works well, but you might begin to leak information into the model as the test fold changes.

Why I Left RapidMiner
For those that are wondering why I left RapidMiner, my dream job, there are no gory details to share. The simple reason is I got burnt out. My time at RapidMiner was some of the best learning and growth years in my entire professional career.

Really cool. My notes are below the video.

VC's Killing Startups
While VC’s are a necessary part of growing a startup, they can kill it too. I’ve seen this happen too many times where the VC’s kill the goose that laid the golden egg. They’re so driven by financial goals that they interfere with great startups that just need a bit more time to ‘gel.’
A recent study commissioned by Eric Paley at Founder Collective found that by pressuring companies to scale prematurely, venture capitalists are indirectly responsible for more startup deaths than founder infighting, technical debt and slow customer adoption — combined.

My Chinese Big Brother - Part 2
Coming on the heels of “I told you so,” China is using facial recognition to make sure you’re a good Chinese citizen.

If that isn’t punishment enough, plans are now in place to link the current system with cellular technology, so offenders will also be sent a text message with a fine as soon as they are caught crossing the road against traffic lights.

Data Science & Machine Learning
When I first self-taught myself ‘data science,’ there wasn’t a lot on the Internet to help me. I spent years cobbling information together reading what I could find about it. Now, there’s a plethora of Data Science and Machine Learning education available. There’s forums, open source libraries and much much more. Most of it is free and damn good. There’s no better time for a non data scientist or machine learning wannabe to learn about it, if you want to put in the time in.

Build a Machine Learning Framework
Great article by Florian Cäsar on how his team developed a new machine learning framework. From scratch. In 491 steps!
He summarizes the entire process up in this great quote:
| *From images, text files, or your cat videos, bits are fed to the
data pipeline that transforms them into usable data chunks and in
turn to data sets,*
| *which are then fed in small pieces to a trainer that manages all
the training and passes it right on to the underlying neural
network,*
| *which consists of many underlying neural network layers connected
through an arbitrarily linear or funky architecture,*
| *which consist of many underlying neurons that form the smallest
computational unit and are nudged in the right direction according
to the trainer’s optimiser,*

How StockTwits Uses Machine Learning to Make Better Products
Fascinating behind the scenes interview of StockTwit’s Senior Data Scientist Garrett Hoffman. He shares great tidbits on how StockTwits uses machine learning for sentiment analysis. I’ve summarized the highlights below:
Idea generation is a huge barrier for active trading Next gen of traders uses social media to make decisions Garrett solves data problems and builds features for the StockTwits platform This includes: production data science, product analytics, and insights research Understanding social dynamics makes for a better user experience Focus is to understand social dynamics of StockTwits (ST) community Focuses on what’s happening inside the ST community ST’s market sentiment model helps users with decision making Users ’tag’ content for bullish or bearish classes Only 20 to 30% of content is tagged Using ST’s market sentiment model increases coverage to 100% For Data Science work, Python Stack is used Use: Numpy, SciPy, Pandas, Scikit-Learn Jupyter Notebooks for research and prototyping Flask for API deployment For Deep Learning, uses Tensorflow with AWS EC2 instances Can spin up GPU’s as needed Deep Learning methods used are Recurrent Neural Nets, Word2Vec, and Autoencoders Stays abreast of new machine learning techniques from blogs, conferences and Twitter Follows Twitter accounts from Google, Spotify, Apple, and small tech companies One area ST wants to improve on is DevOps around Data Science Bridge the gap between research/prototype phase and embedding it into tech stack for deployment Misconception that complex solutions are best Complexity ONLY ok if it leads to deeper insight Simple solutions are best Future long-term ideas: use AI around natural language

Fraud Analytics in RapidMiner
This is a great video presentation on Fraud Analytics use case with RapidMiner. See my notes below.
##Some key concepts
More complex model, the lower the training error but higher test error. Simple models are better, try explaining them to children. Data Scientists understand the technical aspect, need to communicate results with analysts. Sell results to businesses. Tie $ to the results. Speak same language with business. Map performance metrics to business related figures.

AlphaGO Zero learns on its own
The news dropped that Google’s new implementation of AlphaGo, called AlphaGO Zero, was able to learn completely on its own. No training set was first used, rather it built it’s own training set as it played against the older AlphaGO.
Earlier versions of AlphaGo were taught to play the game using two methods. In the first, called supervised learning, researchers fed the program 100,000 top amateur Go games and taught it to imitate what it saw.

Introduction to Deep Learning
This is a great introduction to Deep Learning. I know I learned a few things from Phillip.
Some key concepts RapidMiner now can do GPU deep learning. Supports NVIDIA. Easy: Using already loaded Neural Net operators. Harder: Using H20.ai Deep Learning operator. Hardest: Using Keras with RapidMiner. Keras requires more complex setup with RapidMiner. CNN, RNN, LSTM, etc are now available via RapidMiner GUI. Keras supports Tensorflow, CNTK, and Theano. Need Python v3.

Orange 3 is impressive
I’ve been keeping a lazy eye on Orange over the years and it’s (fairly) recent update has made it quite an impressive contender in the Data Science visual platform space. While it’s not RapidMiner, it does have a lot of great things going for it. First, it’s entire core was rewritten to tightly integrate with Scikit-Learn and Python. It has a decent time series ‘add-on’ which comes stock with ARIMA. It has a really good Text Processing ‘add-on’ that gives the user more finer control that RapidMiner’s and it has a great GEO Map natively.

Weaponizing AI
File this under “no shit Sherlock,” but hackers are already weaponizing machine learning.
The AI, named SNAP_R, sent simulated spear-phishing tweets to over 800 users at a rate of 6.75 tweets per minute, luring 275 victims. By contrast, Forbes staff writer Thomas Fox-Brewster, who participated in the experiment, was only able to pump out 1.075 tweets a minute, making just 129 attempts and luring in just 49 users. via Gizmodo

Product Qualified Lead Model
One of the big corporate strategy things I worked on was developing and putting into production a PQL model. It was essentially a propensity to buy model that analyzed usage patterns on the RapidMiner software platform and bucketed new downloaders into those that were likely to buy or not buy. It was incredibly successful and helped the sales team focus on thier leads better.
My former colleague Tom shares his thoughts on it since it’s been in production for over a year now.

What Works; What Doesn't Work
An important lesson I’ve learned while working at a Startup is to do more of what works and jettison what doesn’t work, quickly. That’s the way to success, the rest is just noise and a waste of time. This lesson can be applied to everything in life.

Is it Possible to Automate Data Science?
A few months ago I read about a programmer that automated his job down to the point where the coffee machine would make him lattes! Despite the ethical quandary, I thought it was pretty cool to automate your job with scripts. Then I wondered, was it possible to automate data science? Or at least parts of it? This general question proved to be a rabbit hole of exploration.
StackExchange has an ongoing discussion into another programmer’s automation of his tasks.

Millennials can't catch a break!
This is just nuts. Millennials just can’t seem to catch a break. Now AI is coming for their jobs.
Research released by Gallup on Thursday indicates a collision between technology and “business as usual” is coming soon, and the fallout will be ugly, especially for Millennials. Automation and artificial intelligence (AI) are among the most disruptive forces descending upon the workplace, says the Gallup report, and 37% of Millennials “are at high risk of having their job replaced by automation, compared with 32% of those in the two older generations.

Startup Funding
ICYMI the Startup markets are getting hotter in the Data Science space. Every time I turn around, some small company got millions of dollars in startup funding. It used to be a company with an algorithm or data science library but now it’s Data Science platforms. These platforms are suddenly all the rage and many new entrants are racing to gain market and mind share.

Big Data and Infrastructure
I have a daily downtime routine. Every evening I set aside about a hour and think. I sit or walk around the house and ruminate about all sorts of random things. Sometimes it’s with a glass of wine and more often it’s with a cup of black tea and milk. Sometimes my mind wanders to what I did that day or what I didn’t finish. Other times I get inspired to write a new blog post or create a new tutorial.

Machine Learning on a Raspberry Pi
It looks like Google is catching up to the idea of machine learning on a Raspberry Pi! Someone put RapidMiner on a Pi back in 2013 but it was slow because the Pi was underpowered.

Needless to say, many French that I talked to are appalled by Donald Trump but some like his authoritative style and that bothers me.

Why I'm Liking Blot.Im
Long time readers know that I’ve struggled with blogging platforms for a long time. I finally opted for a static post approach because it’s safer than the PHP code injections that Wordpress suffers (suffered?) from. The bonus side of platforms like Wordpress is that they have 1000’s of great plugins to download and turbo charge your blog. I really liked this but I got tired of having my PHP templates “code injected” with spam attacks.

Build Your Digital Profile

I reached out to her because we had an opening for a CMO at my old engineering firm and thought she would be great for it. She had recently worked on some really cool NGO campaigns and I liked her forward thinking. I eventually convinced her to throw her hat in the ring for the CMO gig but that’s not the most important thing I learned from our get together.

The Medium is the Message
The one thing that is as important as your product is your messaging about it. In some ways, messaging is more powerful because if no one knows how great your product is, you’re toast.

Your message becomes your product and your product becomes your message.

The experiment came to a grinding halt after I tried to initialize RapidAnalytics. The 2 Pi cluster was ridiculously underpowered and I couldn’t get it to run successfully.

Churn models are not new in the analytics world, they’re heavily used by mobile telcos and other corporations that want to keep their loyal customers happy, and bring back customers from the brink of “about to churn.” In some cases, these models will help classify a group of customers that are such a pain in the butt to keep, it’s better to let them go.

I Stopped Taking Resveratrol
I stopped taking Resveratrol per my Doctor’s orders. About a two weeks ago I noticed my ankles were starting to swell slightly and they went crazy over the Christmas holiday.

The initial blood test results show that my kidneys are spilling proteins into my urine and my Doctor is referring me to a kidney specialist.

Gold Top Or Just The Beginning?
Babak posted about a possible double top forming in Gold (and Oil) in his blog a few days ago. While I agree with his technical analysis on the daily charts, I disagree with his conclusion that Gold has topped out. In my mind, Gold is driven 80% by fundamental reasons instead of technical analysis. If you look at the weekly chart, Gold looks poised to possibly make a run higher after this consolidation.

Solar Heating - DIY
I live in a semi-rural area of NJ with lots of trees, open space, and great neighbors. My wife has gotten into gardening over the past few years and learned that you can “trade” plants instead of buying them at Lowes and Home Depot. She met this old German couple on the other side of town who transformed their 1 acre property into a virtual Garden of Eden and did so by trading plants with neighbors and friends.

Foreclosure Frenzy
I’ve been laying low for a while now with respect to buying and flipping foreclosure properties. You might think that I’m nuts because everywhere you turn now you see and hear about the parabolic rise of foreclosures in this country and the end of the RE world. Although foreclosure activity has picked up and more houses are now being repossessed by banks, I still haven’t smelled enough blood and desperation out there yet.

Forex Trading Overnight
Every Forex Trader I know trades differently. Some are mechanical traders while others are purely discretionary in a nature. Some even use “bots” to trade automatically with little or no intervention from them. No matter what kind of Forex Trader you are, the one thing I learned in trading these insane markets is that when you find something that works, stick with it!
If you’ve been following my $100 Forex Experiment, you’d know that my Forex education has had its ups and downs.

SVM Kernel Application
I promised my readers that I would post about YALE/RapidMiner’s LibSVM operator over a month ago. Unfortunately life had gotten in the way and I’m resorting to a multiple part series to just get the information out to you, so bear with me over the course of the next few days (or weeks) as I write about this exciting, powerful, and complicated learner.
First off, I use the LibSVM operator in YALE 3.

Ayn Rand's Literature of Capitalism
Ugly’s been on the path of discovering Ayn Rand and he posted this article from the NY Times this weekend.
I’ve been a fan of Ayn Rand for many years after receiving a copy of Atlas Shrugged from my old boss Bob. He was the owner of the local 7-11 where I worked the Saturday overnight shift and soon discovered that he was quite the entrepreneur. He knew that I was working two jobs and going to school full-time to help my family make ends meet.

Train Your Mind, Change Your Brain
Since this blog is about using neural nets and AI, its only appropriate that I post about an awesome audio book I’m currently listening too. I like supplement my voracious appetite for books with audio books on occasion and have more space devoted to audio books on my 4 gig nano than I do with music. The current book I’m listening too, “Train Your Mind, Change Your Brain” by Sharon Begely is utterly fascinating.

The Leverage of Subprime
Sherry posted an excerpt from an article she read in my “Real Estate Will Get Worse” post. The author of the article, Jackie Corr, points out an interesting leveraged strategy that is very plausible why hedge funds have been posting out of control losses recently.
If you buy a stock for $36 and sell it for $72 four months later, you’ve made 100% on your money. If you add $30 of borrowed money to $6 of your own to buy the stock at $36 and sell the shares at $72, your profit is $36, but you’ve made 600% on your $6 of which the hedge fund takes a percentage, roughly 2 percent or 72 cents, so your profit is now $35.

Real Estate Will Get Worse
I used to flip foreclosure properties leading up to the height of the RE bubble. It was tough work finding these properties, marketing to them, and then screening the potential sellers. Since I didn’t have the capital to buy the properties myself, for cash, I had to get an investor involved and made a few bucks at it. I learned a lot but realized that it was too time consuming so I stopped.

Macau the Chinese Las Vegas
The last time I was in Macau, I stayed at my brother in-law’s place. Outside his balcony I watched the construction of what was to become billionaire Sheldon Adelson’s Venetian casino. It looked really cool and was massive in size compared to its neighbor, Sands.
The Venetian boasts what it claims to be the world’s largest gaming space of 550,000 square feet (50,000 square meters), housing 3,400 slot machines – with room to expand to 6,000 – and more than 800 gambling tables.

Emerson's Self Reliance
On a random aside, one of my favorite authors from years gone by is Ralph Waldo Emerson. I know that Ugly is exploring Ayn Rand’s Objective philosophies and I suggest he read Emerson’s Essay on Self Reliance as part of his “spiritual” growth.
If our young men miscarry in their first enterprises, they lose all heart. If the young merchant fails, men say he is ruined. If the finest genius studies at one of our colleges, and is not installed in an office within one year afterwards in the cities or suburbs of Boston or New York, it seems to his friends and to himself that he is right in being disheartened, and in complaining the rest of his life.

Dodge & Cox Stock Fund - (DODGX)
My wife owns Dodge & Cox’s Stock Fund (DODGX) and its been a great performer for her account. I just wish they offered it in my 401K! Despite the nice trending chart below, DODGX is not without its risks.
I ran a quick Monte Carlo simulation and discovered quite a few nasty negative return outcomes for DODGX. In fact there’s 0.04% chance for a nasty -51% rate of return over the past 10 years.

SEO Tutorials
I’m in the process of merging and updating old posts with fresh insights and content. I dropped the AI part because what it really means is automation in this sense. Building blog traffic is always about writing great content and observing what Google’s AI does to get you to the top of the search results
AI is just an algorithm that’s built on top of the existing data you have. In a sense you fit an algorithm, to the data instead of fitting the data to the algorithm.

Black Swan Positive
I stumbled across a +45 minute podcast from the Royal Society of Arts yesterday which is highly entertaining, in a quantitative sort of way. The speaker that night was none other than Nassim Taleb, author of Fooled by Randomness and The Black Swan. It’s a fantastic listen to, especially when he talks about something called “Black Swan positive.”
Black Swan Events (BSE) are outlier events, events that you never dreamed of occurring but they do.

Healthcare SPDR - (XLV)
I went long $XLV in mid January 2007 for one of my personal IRA accounts. Its had its share of ups and downs but it doesn’t take a rocket scientist, or a fancy neural net, to figure out that health care is a long term bet. If you don’t believe me, look around for all the graying baby-boomers who want to desperately hold onto their youth.
This time I’m holding XLV for a very long time and won’t be shaken out of it.

Calculating Historical Volatility
The inspiration for my S&P500 Volatility Timing model came from rereading portions of Mandelbrot’s book, The (Mis)Behavior of Markets, and trolling around the Internet for Nassim Taleb’s research work on risk. I think both guys push the envelope on truly understanding unseen risk and those pesky financial asteroids. Since my model is currently being developed, I thought it would be worth my while to truly learn and understand how historical volatility (HV) is calculated.

Chipotle Mexican Grill, Inc. - (CMG)
CMG is hitting an all-time high these days and after eating their tasty food, I can understand why. Good food at high prices is always a surefire way to make your stock a winner, until your fickle customers become cost conscience.
My favorite dish is the chicken burrito bowl w/ sour cream and the red hot sauce. :)
Update I posted about this stock back in May 2007 when it was trading at $82 or so and now, in 2019, it’s way higher.

Guide to AI Transformation
Thirteen years ago I made a simple post about building neural net models. Since then, the field of applied machine learning and data science has changed a great deal. Over a single decade new tools and the open source movement have altered how companies do ‘AI.’ They moved from data mining data in databases to building data lakes and clusters. Now, small to large companies are seeking ways to harness these tools under the umbrella of ‘AI.

Daytrading on Steroids
I’ve posted this article before on my old site and thought it was fitting to re-post it here. It’s a story about a company called Tradebot Systems, Inc. CEO David Cummings, a former commodity pit trader and programmer, built an Automated Trading System, or Tradebot, which trades between 50 and 100 million shares a day! Wow!
Tradebot trades 50 million to 100 million shares a day. Anywhere from 1 billion to 2 billion shares trade daily on Nasdaq.

Semiconductor Holders (SMH)
Howard wants to buy put options on SMH. Me? I will wait and see which way she breaks from this narrow range, which started in mid 2005, before I do anything. Has it been trading in range for that long?
My guess is that semiconductors aren’t the technology darlings they once were, maybe its because chips are more of a commodity now.
Disclosure: Long INTC from years back.
Update Here’s a perfect case for long term passive investing in an ETF.

Agriculture Index - ($GKX)
I worked in my vegetable garden for most of the weekend and with every weed I plucked, the words “Ethanol” and “bio-fuel” kept popping in my head. I know that everywhere I turn, I see and hear about how Ethanol is going to save us from oil dependence and global warming.
Despite my skepticism about Ethanol, I am curious to know what set of this new trend in the Agriculture index?

Xinhua China 25 Index - (FXI)
I’ve been following the China iShares, FXI, for a long time now and I noticed that Maoxian posted about it nearing its all time high. This reminded me of the time when the talk was that FXI might be overextended or possibly reaching a top. At the time, it sure looked that way. I even posted on my old site saying that the trend might be over but the more I thought about it, the more I wondered if my initial call was wrong.

Financial Asteroids hit Trends
Several years ago, when I was living in New Mexico, I had a girlfriend who used read very esoteric books about cutting edge theories on biology, evolution, and astronomy. We were talking about “what-if” scenarios one day and the conversation drifted to some called “punctuated equilibrium.” It was explained to me, at the time, that species evolve slowly in an environment that’s in equilibrium. A sudden leap in a species evolutionary development happens when a catastrophic internal or external event occurs.

Automated Trading
In my old blog, Digital Breakfast, I posted a few times about my desire to build an Automated Trading System (ATS) using Excel. I figured I’d build it in Excel since I know that software the best and conveniently enough, Interactive Brokers offers an API for Excel. Today, I located my old real time ETF Trend Signal system, which is based on statistical performance measures to generate trend signals, and decided to begin additional back end development on it.

AAPL over the years
There’s something to be said about buying winners. Winners continue to win, and in the case of stocks, they keep making new highs. I know that AAPL is a favorite holding of Howard and his hedge fund’s strategy of finding and investing select stocks making new 52 week all time highs is a smart. The trick is to buy the right company making the high.
It’s safe to say that Apple is the right company, its emerged as an innovative powerhouse once again.

Wall Street Using AI To Trade
I heard this first on Bloomberg Radio and then found the article. It’s about the ever increasing use of data mining and AI in the financial markets.
In his cubicle overlooking the trading floor, Kearns, 44, consults with Lehman Brothers traders as Ph.D.s tap away at secret software. The programs they’re writing are designed to sift through billions of trades and spot subtle patterns in world markets.
Kearns, a computer scientist who has a doctorate from Harvard University, says the code is part of a dream he’s been chasing for more than two decades: to imbue computers with artificial intelligence, or AI.

Motorola - (MOT)
Sometimes trends have intra-trend reversals (which are great selling or buying opportunities) and then quickly resume their trends. Motorola tried to break free from their down trend, and almost succeeded with the introduction of their wildly popular Razr phone (I have one). With no new innovative product followup, MOT resumed its downward trend.
Update Just over 12 years ago I posted about how [Motorola (MOT) was in a downtrend because it couldn’t come up with a new breakthrough product.

Real Estate iShares IYR
Could the trend party in IYR be over? Maybe.
A lot of information can be gleaned from observing a price chart, mostly technical information. A lot of traders/investors forget that fundamental and sentiment information also drives prices up or down.
Learn Stock Trading, Investing, and Risk Management There are a handful of financial and trading books that have made a HUGE impact on my investments. If you want to trade and learn about money and risk management that I suggest you get the Tharp book.

$100 Forex Experiment
Good Morning. Yesterday’s currency sell-off triggered several of my buy orders as the EURUSD and GBPUSD pairs dropped through support after support. The end result was that I started to pyramid losses. However, I stuck to my trading plan and planned for a long wild ride. In case any new readers are wondering, I will (re)post my trading plan on this blog later today.
Finally, overnight the pairs started to firm up and now my GBPUSD pair is showing a nice profit as it heads back to the magic $2.

EWM ETF Past & Present
EWM was good to me in the past, too bad I sold it!
Update EWM. What a great ETF for investing into the Asia area. This is one of those emerging market ETF’s that I should’ve held onto for the past 13 years. Once again I’m going to repeat what I wrote about passive investing: diversify, buy low cost mutual funds/ETFs, and dollar cost average.
Look at EWM now, trading around $27.

FXI Trend Remains Up
My FXI neural net model continues to show an UP trend. Nice to know! :)
Update I realize that after 13 some odd years, this one sentence blog post with a FXI chart is very much out of context. This post was a simple confirmation of a model I built for trading/investing in this particular ETF. This was the early days of my learning Data Science and boy was my model wrong from the start.
