Triplebyte fun or not

This probably breaks their terms, but facebook keeps annoying me with ads for Triplebyte so I decided to spend a few minutes to go through one of their tests to see how I fared.

The first question is pretty easy. Instead of spending a few minutes to see what the function does, being a ~~lazy~~ typical engineer, I just pasted into the chrome dev console. I guess they assume everyone is a javascript dev.

Next they collect all your information, I assume so they can farm it out even if you don't fare to well, haven't read the terms. Then you to pick a quiz. I chose the Android one, and well 30 minutes or so later I got to schedule an interview.

I was pretty upset that they gave no indication of my score. Instead of helping me actually learn what I may have got wrong with the 30 minutes I spent taking the test, they could at least say a percentage. I get they don't want to let people cheat, but come on, what a ripoff for my time.

So for kicks, I went and answered everything wrong to see what they say.

I passed again, with every question wrong! Just no interview of course. Instead of saying, sorry you didn't fare so well, they say "Great you passed" (which is a deliberate lie unless the passing score is 0), now go do another test.

Interesting their referral is $1500. Since most companies will give a referral bonus of around $5-10k it seems like a pretty lucrative business.

Anyways thought that was fun, but if you're simply trying to see how well you do, don't waste your time if you expect any kind of feedback!

Cheers!

Kivy vs React-Native for building cross platform mobile apps

I've built three apps now using Kivy and one with React-Native, just wanted to share my thoughts on both. Just a warning, I am strongly biased towards python and this is all based on opinion and experience and is thus worth what you pay for it. I don't claim to be an expert in either of these, just have worked with each for several months. If something is incorrect I'd love to hear advice. Kivy Demo of one of the apps Pros: Nice to be able to run natively on the desktop WITHOUT a simulator Python is easy to work with Use (almost) any python library Very easy to create custom widgets Kivy properties and data binding just work. Way nicer than React's "state" / flux / redux whatever you want to call it (stupid?). Native interfaces (pyjnius) and (pyobjc) Runs and feels pretty smooth Cons: Default widget toolkit looks like Android 4.4. Requiring you use your own widgets or a theming kit like KivyMD if styling bothers you Creating dy

Control Systems in Python - Part 1 - Bode and Step Response

I hate matlab with passion, yet sadly, nearly everyone uses it. I'm a fan of Python and open source stuff so here's a simple article on how to do some common control systems stuff in Python. First we need to make sure the environment is setup. Install IPython (or you can use any other python shell, but a unicode supported shell is preferred) Install python-control (numpy, scipy) Install sympy These should do if your on Ubuntu/debian: sudo apt - get install python - sympy python-numpy python-scipy python-matplotlib ipython Then you need to install python control, see How to download and install python-control Intro to using Sympy Open ipython and run the following: import sympy from sympy import * sympy.init_printing() s = Symbol('s') Now we can do things like define transfer functions using the symbolic variable s. We can expand the bottom using the .simplify() method and we can do something more complex like... which is really nice because it

Control Systems in Python - Part 2 - Routh Hurwitz

In my last post Control Systems in Python Part 1 , i described how to setup and use Python for doing some basic plotting of transfer functions. One of the biggest benefits of using sympy vs numeric packages like matlab/numpy/scipy is the fact that you can use symbolic variables. This post includes a function for computing the Routh Hurwitz table (Note: It does not work for row's of zeros). Lets do my control systems design homework problem together :) (Warning: I have not verified if this answer is right so please correct me if it’s not!) The Problem The problem is DP 9.11 from Dorf & Bishop’s Modern Control Systems. ISBN 0136024580. Basically we have to design a controller to compensate for a system with a time delay. The controller is: And the system is: First we approximate the exponential term with a 2nd order polynomial using pade(0.4,2) such that: Thus the approximated system is: Using frequency response methods, design the controller so that th
