Most or all governments in the world employ an education system that can be described as multi-stage lecture-based, and it works like this. There are about a dozen stages of increasing density and complexity, each has a duration of one year. During each stage, there are a bunch of courses about a variety of topics. Each student then must attend daily lectures, solve many assignments, study these courses, and pass all the exams with sufficiently high grades. Only then the student can move on to the next stage of the system and go through this whole process again, except that with courses that demand more time and effort. This system is implemented by building and maintaining many schools and colleges and hiring teachers for all the courses in all the stages and staff for doing the managerial and maintenance work. This is more or less the same system that has been used for hundreds of years, before the invention of any electrical machines.
Does this system work? Continue reading
Many people are curious to know what the most popular programming languages are in the sense that they are being actively used to write code. This is usually done annually. If you look this up in your favorite search engine you will probably find many lists or charts. Among the most prestigious websites that produce charts of the most popular programming languages is IEEE Spectrum. Their list for 2016 can be found here.
While they use many sources to reasonably sort languages by popularity, the list of languages they show is not really meaningful. Continue reading
Humans somehow construct opinions that may conflict with each other. How do you determine that something is true? Seriously, how do you determine that a statement is irrefutably true? If you can say that a particular statement is irrefutably true then those people who disagree can be fairly called illogical. More importantly, we can confidently build knowledge upon it.
For the love of all decidable things, watch this video!
In this article, I would like tell you about my personal opinion regarding why the world is so messed up. I do not intend to offend, insult, or attack any person or group of people in particular, and everything I mention or say here is just for the sake of making a point. Of course, since this is a blog about computer science and mathematics, I will be using an example from elementary mathematics to explain why the world is so messed up. Let’s start with watching this video very carefully: Continue reading
Once upon a time, I was reading mysterious lecture notes about algorithms. And then, a wild sentence appeared:
Wouldn’t the sentence “I want to put a hyphen between the words Fish and And and And and Chips in my Fish-And-Chips sign.” have been clearer if quotation marks had been placed before Fish, and between Fish and and, and and and And, and And and and, and and and And, and And and and, and and and Chips, as well as after Chips?

My first response was: yest it would!
However… Continue reading
