# Implement a Truth-Machine
A truth-machine (credits goes to this guy for coming up with it) is a very simple program designed to demonstrate the I/O and control flow of a language. Here's what a truth-machine does:

# Question #7f781
##### 1 Answer
Nov 16, 2014
This is just pure coincidence that
$2 + 2 = 2 \cdot 2 = {2}^{2}$
4 is a perfect square number, meaning that if you multiply a number (let's say $a$) by itself, then you will get $a \cdot a$ or ${a}^{2}$.
$3 \cdot 3 = 9$
That means 9 is a perfect square. But 6 is not.

Who cares whether some computer program is a whole, how, and why? Turns out, more people than you may think—and so should you, since it can be costly depending on the answer. Consider the following two scenarios: 1) you download a ‘pirated’ version of MS Office or Adobe Photoshop (t... | |
## Algebra 2 (1st Edition)
You should use a calculator for this problem. We need to focus on rounding correctly. Since this is a solitary calculation, we will round 5 up always. We get 8.74 after plugging this in. $8.74$ is the rounded answer | |
Avoid storing the whole message when signing with SPHINCS+
Unlike pretty much every other signature scheme that I am aware of (excluding Picnic, the original SPHINCS, and SPHINCS-gravity) SPHINCS+ requires that the whole message be available during the signing operation. This is because it uses a "message randomizatio... | |
# Finding option price using intraday data [closed]
I have the option price at a rate which is much smaller than the rate at which I have tick data for the underlying. If I have option price at times $$t_1, t_3, t_5$$ and I have tickdata at $$t_1, t_2, t_3, t_4, t_5$$ can I find the option price at $$t_2, t_4$$ ?

# GAZEBO doesn't find mesh file in URDF.
In ROS2 I have created a python package called "mars_robot" which simply includes the URDF model of a robot and a "launch" file to start the simulation in Gazebo. This URDF model uses mesh files that are included with code lines like the following:

# Extras: Running in Parallel
Back to Course Overview
All modern DFT codes are capable of running in parallel, provided they have been compiled to do so. While you may be familiar with a single application using several threads when you start it so that it runs faster, the parallelisation scheme used by many DFT code... | |
Stuck solving a logarithmic calculation
I'm preparing for my further studies (last year of high school, preparing so I can try and join the academy that I want), and just solving problems. Got stuck on this one:
What is the value of: $$log_4log_3log_28 + log_{\sqrt{7}+1}(8+2\sqrt{7})+log_{\sqrt[3]{7}}7\sqrt{7}$$

# Numerical Methods/Errors Introduction
When using numerical methods or algorithms and computing with finite precision, errors of approximation or rounding and truncation are introduced. It is important to have a notion of their nature and their order. A newly developed method is worthless without an error analysis. N... | |
