The first rule of cryptography is never to implement one yourself. “It’s going to get crushed to dust by anyone who knows what they’re doing”
I do believe that everyone deep down at one point in their lives has thought that Cryptography — the art of writing and solving codes — is fascinating and considered learning more about it. People want to keep secrets safe, and people want to know the secrets of others.
When I was a young child, as a game, my friends and I used to make “cipher algorithms”. These were basically just substitution ciphers with…
Adversarial Examples for Humans — An Introduction
This article is based on a twenty-minute talk I gave for TrendMicro Philippines Decode Event 2018. It’s about how malicious people can attack deep neural networks. A trained neural network is a model; I’ll be using the terms network (short for neural network) and model interchangeably throughout this article.
The basic building block of any neural network is an artificial neuron.
Essentially, a neuron takes a bunch of inputs and outputs a value. A neuron gets the weighted sum of the inputs (plus a number called a…
The purpose of this learning plan is for anyone to acquire a strong foundation in electronic and mechanical prototyping to build your own physical robots. You will learn coding along the way, so I could say coding is not required but it’s easier to follow if you’ve already coded before. It is designed for anyone who has literally zero background in electronics and/or robotics. Upon completion, you should be be able build your own domestic home service robot and you should also have the confidence to independently build the robot of your dreams. There are many good tutorials scattered all…
Bitcoin has had quite a year this 2017, up to more than 1700% increase year to date (checked on Dec 17, 2017). With this exponential increase, comes an equivalent interest in mining them. Some think it’s a scam, while others think it’s a great investment. Given what I’ve seen online, and the many variables involved, I haven’t really encountered a thorough article that allows me to draw an unbiased conclusion by myself. This article is my attempt to gather my thoughts and hopefully provide that.
TLDR: It’s ok. I don’t really recommend it. I think there should be twice as much content, and much better presentation at half the price. There are a lot of free content out there that give a much better presentation of the topic. Here’s a compiled a list of curated resources.
Right now it swerves like a crazy wishy-washy undecided driver and ironically too conservative at keeping its lane at the same time.
Given our sensor information, how do we decide whether to turn left, turn right, or stay in lane? This got me thinking, there are many things we can consider. We can consider the speed and acceleration of nearby objects for example. For example, if leading car in that lane is faster than the leading car in our lane, that’s awesome. If the car at the back of us in that considered lane that we are cutting is moving…
