Tesla Next Batch Algorithm

//If you are reading this, I suggest you skip it. You have been warned. At some point, Tesla will face the decision: [which car to make next?] Hardware specifics that exist tangibly including paint colour, # motors, performance, battery size, r/l hand drive etc. need to be built in batches. Tesla will want to minimize […]


Bose Quiet Comfort 15 Headphone Review

I don’t do many product reviews, but I thought I would do one for this set of headphones I have been using for a couple years. Spend some hundreds of dollars. Sound quality has been basically subjectively perfect. It is how I expect things to sound now. Since headphones are so close to your ears, […]


Hater’s gonna hate

This article from The Drive does well to draw parallels from industry envy and how leaders suffer from envy in the industries they disrupt. He points out that he loves his car and Tesla is way ahead. He points fingers at all other car dealers and accuses them of not stepping it up. And points […]


Why is growth the most important metric?

My name is Jeff. I am going to buy a lemonade stand. This lemonade stand costs me $100. But for every $80 I spend on labour/ingredients expenses, I make $100. My first year, I only ran the one stand. I spend $100 on the stand and $80 on expenses. So I ended up -$80. Instead […]


Sentry Mode 2.0 (or 3.0?)

On Aug 10 2018, I originally wrote about a Tesla intrusion detection system. It wasn’t spot on, but it basically foresaw Tesla using cameras to detect intrusion. As of a few weeks ago Sentry Mode has been updated to stay on and allow you to input more settings such as the ability to configure when […]


Tornado Gun

It’s been a pretty crazy red wine night. So let’s see how this blog turns out. My idea is a Tornado Neutraliser. Based on research from NOAA let’s assume we can compute with cameras tornado physics real-time. That is, we can point a camera and detect different physical points of velocities from atmospheric movement at […]


Internet Everywhere

In Canada, it is hard to cover all the ground. Many of my favourite spots have poor connections. Places I could never live because I couldn’t work. Places I can’t stay long because I need to get back to an internet connection. And for my spotty internet connections I pay for cell phone and home […]


What makes a better battery?

More juice Faster charging and discharging Longer lasting/more cycles Cheaper to produce/minimal human labour Faster to achieve high volume production Produceable in surplus Resources involved more abundant/cheaper/ more environmentally friendly/sustainable Less friction to achieve high volume production More stable/less likely to explode or catch fire More cold weather endurable/minimal cold soak Self healing if possible […]


Running Crons in Paralell – FAIL

Problem: We have dozens of clients who obtain pricing files (csv,xml,other) from distributors.  Clients have an average of 2.5 distributor files.  Each file has an average of 400,000 products.  The process to update pricing distributor for a single client can be run via the command line : run cron.php Running a single pricing update is […]
