The problem statement: We are tasked with prompting a user to enter a specific type of value, validating the value and print a message appropriate to the value provided. The following are a set of requirements for this task: Prompt the user to only enter a non-negative integer. For example, the following are examples of non-negative integers. 0, 1, 2, 3, 4, ... If the user successfully enters a…
The problem statement: We are tasked with displaying all the powers of 2 less than 1,000 along with a message describing the output. The following is the expected approximate output of program 5: 1 2 4 8 16 32 64 128 156 512 These are all the powers of 2 less than 1000 The Solution: def powers_of_two_less_than_one_thousand(): power = 1 while power < 1000: print(power) power *= 2 print("These are…
The problem statement: Program 3 introduced an operator that increments the value of a variable by a desired amount, namely, the += operator. Recall that the use of this operator allowed us to replace this expression variable = variable + 1 with the following concise expression variable += 1 . Because this operator first computes the sum of the existing variable value with the desired constant…
The problem statement: Program 2 showed us how to iterate over a list of numbers and print them to the screen. For our next program we will also need to iterate over a list of number but this time we need to count the two different types of numbers in the list as we iterate over them. The task is to write a Python program that displays the counts of odd and even numbers in a list of positive…
The Problem Statement: Program 1 showed us how to iterate over a range of numbers with the use of a for loop and the range function. Suppose instead of a range of number we have a bunch of numbers that are contained in data structure called a list . Given a list of numbers, how do we iterate over it using a for loop? The task, just like program 1, will be to write a Python program that displays a…
The problem statement: Program 0 provided a solution to the problem statement but it is an inefficient way to salve it. The solution required us to perform repetitious work. For that problem we only had to display the numbers from 4 to 9 along with its square. Now imagine if the problem required us to display numbers, along with their square, from 4 to 79. Our solution with be unnecessarily long…
The problem statement: The task is to write a Python program that displays a list of numbers from 4 to 9. Next to each number, the program will also display its square. The square of a number is computed by multiplying it with itself like so. 4 x 4 = 16. Here, 16 is the square of 4. The following is the expected approximate output of program 0: 4 16 5 25 6 36 7 49 8 64 9 81 The Solution: def…

Wikileaks has begun dumping a large number of files on the CIA's hacking tools. The dump is called Vault 7 . It is a goldmine, not only for information about the CIA's activities, but also for information on things like how to set up a development environment or properly use Git in your everyday programming workflow. Here are a couple highlights from some cursory searches of the document dump: CIA…
In this article, we'll provide a few tips and tricks on how to use a couple simple advanced web searches to browse a website without actually visiting the target site, effectively remaining invisible to the site's proprietors. Maybe the website is blocked on the computer you are using. Maybe the site seems somewhat sketchy and you want to check it out before you actually visit it. Maybe you want…

It is becoming increasingly difficult to distinguish fact from fiction in the coverage of Wikileaks' ongoing publication of internal emails from Hillary Clinton's presidential campaign, known as the Podesta emails. There are internet hoaxsters pushing fake emails that are not contained in the actual published files. There are junk reports from prominent newsy websites that are based on obvious…
Image via Hoax Slayer We all know the internet is rife with falsehoods, misinformation and disinformation. And, sooner or later, we're all bound to be taken in by an internet hoax, whether it is a fake news article, a photoshopped image, an advertisement masquerading as legitimate content, or even a government-sponsored propaganda campaign. In this article we'll use a real-world example to take a…
Good morning / afternoon / evening (depending where you are on this fine planet), space fans! Here's what's been up lately in low-earth orbit! Lookin' good, homeworld! The Northern Lights were so strong this week, Reykjavik, Iceland turned off their streetlights to watch the whole show. (Image courtesy NASA.gov.) NASA Astronaut Kate Rubins, who recently became part of the first team to sequence…

As of August 21, Williams had served a…
It sounds like something out of the future, but it's actually in operational trials for human beings right now: a new type of surgery that uses ultrasonic sound waves to target specific neurons for eradication, thus healing certain brain malfunctions non-invasively... This is a "song" that can heal certain brain anomalies, if it gets stuck in your head properly. (Image courtesy itnonline.com.)…
It seems that the only technology progressing as rapidly as the robots who are going to take your jobs is that of 3-D printing. Capable of creating clothes , huts , offices , art , prosthetic limbs , space station parts , and more, the science has now expanded to being able to reproduce the organs that are used to reproduce. Even though they actually work, can we please call them "faux-varies"?…
Sometimes, it doesn’t take Wikileaks or the Russians to make a hack that changes everything. Even a small-scale rerouting of the information superhighway can have an impact on everyday humans, and possibly even work in everyone’s best interests. That was the thought behind this one unassuming new invention… The Internet of Things? How about the NON-Internet of Things? (Image courtesy news.co.au.)…
