It is 2021. And we have #AI writing #AI code. 🤪 It is quite interesting, but also can be quite boring once you get beyond the initial technology, and just think of it as one of the tools in your arsenal. And getting to that point is a good think. As part of a think at work I recently started playing with GitHub Copilot , which is using GPT3 to be your pair programmer – helping write code. GPT3 has multiple models (called engines), and Copilot uses one of these family of engines called Codex. Codex is a derivative of the base GPT3 engine that is trained on billions of lines of code. ...

Reinforcement Learning is teaching by example – it is how most of us learn. Reinforcement Learning (#RL) is a different approach to ML – it is a set of techniques that allows AI algorithms to experiment and learn from experience. RL falls in between supervised and unsupervised learning – there isn’t any labeled data, but at the same time it isn’t unsupervised either. At its most simple form, RL is a computational approach for automating goal-oriented decision making and learning. ...

I have been kicking the tires with Open AI’s #GPT-3 . Based on the screenshot below, it might be easy to think “oh boy does the model think highly of itself”, but as with most things in life - the devil is in the details.😃 The screenshot below was a forked version of davinci engine and follows the Q&A structure. ...

A #ML algorithm cheat sheet - helping narrow down to a certain set of #algorithm grouping depending on the problem at hand and what we are trying to solve from a business perspective. ML algorithm cheat sheet Figure 2 shows what additional characteristics we need to consider when choosing the right ML algorithm for your situation at hand. This is something that cannot be generic and is very situational. ...

If you are like me and get annoyed with the big PowerShell upgrade ’nag’ ‘reminder’ (see screenshot below); instead of trying to figure out what to download and install the update, there is a simpler way to get the latest update and address the nag. :) You can just run the code below in an elevated prompt to get the latest release of PowerShell - it is easy-peasy. :) ...

If you are like me, and don’t really have your work saved in the “%USERPROFILE%” it gets annoying after a time, to keep changing the directory. If there is one specific folder that you prefer, it is an easy configuration change in the profile setting - add a setting called “startingDirectory” and point it to the path you want. For example, I have a root folder called “src” where most of the code I am working on sits, and that’s where I wanted to default the terminal to. ...

Floating point calculations are slow for computers (specifically CPUs); possibly representing the same struggle for many humans. :) I remember a time when a FPU (floating point unit) was an upgrade and one had to pay extra to get one. Very useful when you needed that extra precision in computing - and in my head, it always seemed like the Turbo button. :) ...

One of the key advances in the latest version of Windows 10 (2004) is WSL2 (Windows Subsystem for Linux v2) - and whilst a version bump, it offers so much more. This allows us to run with near-native performance linux binaries ( ELF64 ). Before we get into the steps outlined to install WSL2, I also recommend installing Windows Terminal , and winget . Although not required, it does make it simpler to use and a better (dev) experience - especially when setting up a new workstation. ...

I recently needed to get a list of users that belong to a specific Microsoft Teams team - and there isnt anything out of the box to get this using the Teams app. AFAIK, the only way to do this is using the Microsoft graph API - for which there are a few options. For something quick (e.g. getting a list of users in a team), using the Graph explorer could be easy enough. On the other hand, if you need something more robust, you should program against the (REST) API. ...

With everything going around us - this is what 2020 feels like. 😮‍💨 1 2 3 4 5 6 7 // Livelock == an infinite loop that // means the program is frozen #define FROZEN while(1) // in hell, there are demons with pitchforks #define HELL fork(); FROZEN HELL

I think this from xkcd sums up my afternoon quite nicely. Messed up a repo, and then was trying to ‘clean up’. A huge thank you to Lily, on the team, for working with me to cleaning up my mess, and helping me show some of the ropes. I know there are quite a few tutorials out there; a couple of these that I found including one from Lily. ...

If you have butter fingers like me, and over time end up with a lot of old commands with typos in your Windows run box that get annoying - deleting them is a simple. All you need to do it remove the following registry key. 1 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU Now every time one plays with regedit, it can be dangerous - you can also save this commend as a .cmd file, and then run it with admin privileges - essentially does the same thing. ...

Been playing with a few things at home, and as part of that was trying to get Docker and Docker Compose running on a Raspberry Pi. Docker Compose if you aren’t familiar with, allows one to run multi-container apps, and is very handy when building multi-tier layered applications - which are quite common. ...

Haven’t had time until now to explore on what is new as Tesla continues to push updates. The latest version as of this post is v3.9.1 which is what there I decompiled and when compared to the earlier version ( I had posted (v3.8.2) , there three new REST API’s outlined below. Service data from the car - not sure what exactly does this will. Need to try it. ...

Minor Fixes

This is a output of a few frustrating hours (spanning over a few days - as and when I can get time), and finally got it fixed and working. Hopefully it might help someone who is also dealing with npm blues. When NodeJS and npm works, its awesome. But when it borks, it is worst than my code or so it seems :). Been playing with a few things and wanting to get a dashboard going with Grafana (and InfluxBD as a time-series DB). But some of the installation was failing and for the life of me, could not figure out why and how. Clean image install and downgrading to the previous stable version also didn’t help. ...

Sometimes one needs a quick snapshot of what are the options to think through and I really like this for that. Machine Learning Algorithms

A key virtue of a programmer is laziness. As an example it is what inspires me to automate my home to the point where I don’t have to lift a finger to switch on the light. Removing friction from a system is a anesthetic joy. The drug of efficiency, feels really good. I still write code and people get surprised by that sometimes - maybe it’s the quality of the code 🤓. ...

It has been a while since I played with the various Tesla endpoint (APIs) - been too busy and haven’t had the time. I de-compiled the Tesla app and noticed a few new things in there - or at least new to me. The following are the ones which seem new and stand out. How exactly some of these are used, can only be one’s guess, but I can certainly infer a few things from this. ...

I have been playing with a #selfdriving car for a while , and that is super exciting. From a #AI and #ML perspective it is small scale but allows one to exploit all aspects of the tech stack and also appreciate the limitations of not only the software but also the hardware. With this, You run a NN on a raspberry pi that uses TensorFlow, and Keras and run inference on the edge. The pi doesn’t have enough power to train, so you need to do that on a beefier machine and then deploy the model back to run this. ...
