Published

How does a computer virus infect a system? Much like a biological virus, computer viruses spread and replicate from one host to another, infecting a large number of computers quickly and causing mayhem and destruction. Computer programmers use languages like C, C++, C#, Java, Perl, PHP and more to write computer programs, this code can also be used to create viruses with malicious intent. Creating a computer virus is not illegal, but if it causes harm to other systems, the person who created it may be held liable for damages. Some of the world’s most infamous and devastating computer viruses can be found here in a timeline from HP.

Researchers agree that the first computer virus was circulated back in 1971. Called the Creeper virus, this program infected computers in a non-malicious way, simply putting a message up that said “I’m the creeper, catch me if you can.”

Computer viruses didn’t get big media attention until 1988 when the Morris worm was released causing over 228 million in damage in today’s money. In the early 2000’s when personal email was truly starting to take off, computer viruses exploded through mass-emailing schemes. The ILOVEYOU virus (released in 2000) was a fake love letter that would send itself to every contact in a person’s email list once opened. In 2001, a virus called KLEZ was estimated to infect over 7% of the computers in the entire world by sending fake emails and tricking victims into opening them by pretending to be trusted senders. It caused over 48 billion dollars in damage after inflation making it the 2nd most destructive virus on this timeline.

Published

on

Schools in the US are facing a lot of problems and one of the biggest is how they treat their teachers. If you have ever been on the r/Teachers subreddit then you know exactly what I am talking about. The subreddit is becoming more and more filled with complaints about teaching. The complaints range from disinterested kids and unruly parents to administrators that seem to care about state-sponsored standardized test scores more than anything else.  You would think that with all the teaching shortages and the upheaval created by the COVID-19 pandemic, teachers would be seeing an increase in salaries, but this graph shows that new teachers today are actually earning 11% less than their peers from 30 years ago.

With inflation in mind a starting teachers salary today should be around $46,762 but today they are only making around $41,780 on average. Looking at the graph you can see that since 1990 the salary with inflation and the actual starting salary have been pretty close to one another until you get to 2022 where you see such a large difference. If things don’t change soon, students will continue to suffer. Students are already considered to be behind due to disruptions from the pandemic. Good teachers are needed now more than ever, so let’s pay them what they deserve.

How the Price of a Big Mac Has Changed Around the World (2000-2022)

Published

on

The iconic Big Mac is a two-beef patty, three bun delicacy topped with iceberg lettuce, American cheese, pickles, chopped onions and the super secret Mac Sauce. In 1968, it was so popular with its limited release in Pennsylvania that it was rolled out to every McDonald’s restaurant across the United States. That popularity never waned and there is now an entire economic phenomenon known as ‘burgernomics’ modeled from the Big Mac. Economists will use the price of the big mac as a way to gauge inflation rates and economics across globe. Today the Big Mac is up 40% from 2010. We can see in this video visualization by /u/jcceagle that follows the price of a Big Mac over the last 20 years, just how different cost can be across the globe and over time.
In the year 2000 Norway had the most expensive Big Mac for $4.09, while in the Philippines it cost $1.17. Eight years later, Norway still tops the charts with the most expensive Big Mac but instead of just over four dollars, it increased to $7.88. At that time in the US a Big Mac cost $3.57 while the cheapest was found in Malaysia for $1.70 and the Philippines increased to $1.96. In July 2017 the most expensive Big Mac was down across the board from 2008 to $6.74 in Switzerland. That same year a Big Mac in the US would have cost you $5.30 and $1.70 in the Ukraine. The video also shows an index of currency valued relative to the US dollar where you can see the values changes across the different currency around the world.

Starting in the year 1900 only 4.8% of the total national debt was held by the public. After World War I in 1910 that percentage jumped to 10. In 1920 following the Great Depression that number doubled to 22.9%. Ten years later that number would be in the billions, 16 billion to be exact with President Roosevelt’s New Deal in 1930. World War II would see this number jump to 40 billion or 75.1% of the GDP. The Korean War of 1950 would add hundreds of billions to the debt clock in only ten years bringing the total in 1950 to $257 billion but bringing the GDP down to 56.8%. The next big increase would come in 1980 when president Reagan introduced his tax cuts causing the gross debt to jump to over 900 billion. Ten years later it would see another massive jump to over $3,233 billion dollars with the Gulf War. Thirty years later the COVID-19 pandemic caused the average debt held by the public to sky rocket to 105.6 percent in 2020 , over $27,748 billion dollars.
