What Is Cloud Computing?

When people speak of “the cloud,” they’re usually talking about cloud computing. But what exactly is cloud computing? We’ll explain in the paragraphs below.

Most businesses need servers, storage, databases, internal networks, software, analytics, and more. In the past, they used their own resources to accomplish this. They bought their own servers, created their own networks, and hosted their software and databases internally in on-site data centers.

Cloud platforms like Amazon Web Services, Google Cloud Platform, and Microsoft Azure changed this. Cloud computing offers the same type of capabilities to businesses, but there’s a difference — companies don’t have to worry about hosting this infrastructure. We recently launched new free courses that help you get started learning about key cloud providers like Azure, AWS, Google Cloud, and CompTIA Cloud Essentials+.

What is cloud computing used for?

Cloud computing provides the services listed above to businesses over the internet. Using a cloud platform relieves IT professionals from many of the responsibilities involved in maintaining these services, allowing them to focus on more important technical issues.

Another benefit of cloud computing lies in pricing. Businesses only pay for the cloud resources they use, which can lower costs, make their infrastructure more efficient, and allow services to scale as their needs change. Here are some things that cloud computing makes possible:

  • Speeding up application development time by using cloud resources that can be quickly scaled up or down
  • Easily analyzing data across the business from a single location in a connected cloud environment
  • Streaming audio and video with minimal lag, no matter how many users are accessing it
  • Delivering the latest version of software on-demand, anywhere in the world
  • Storing, backing up, and recovering data quickly, easily, and without worrying about data integrity

Benefits of cloud computing

Most modern startups begin with cloud computing instead of using their own data centers. Many traditional businesses migrate their traditional infrastructure to the cloud because of its benefits over the older model. Let’s explore some of these benefits.

Cost

Using a cloud provider eliminates the cost of buying hardware and software and creating and managing an on-site data center. This means no extra expenses from the racks of servers, the electricity they use, and the IT staff dedicated to managing them.

Speed

If you need more resources in an on-site data center, you have to buy the hardware, install it, and provision it. With a cloud-based infrastructure, you can provide this type of infrastructure in minutes, usually with just a few clicks of a mouse.

Scalability

Cloud services can scale elastically. This means that they can provide the right amount of resources when needed, and businesses never have to pay for more than they need. With a traditional on-site data center, a company typically has either more or fewer resources than they need.

Productivity

Because a business’s IT professionals no longer need to set up the hardware for servers, patch software, or perform other time-consuming tasks, they can spend more time achieving business-advancing goals.

Performance

Cloud providers have a worldwide network of servers and resources that are updated regularly to the latest hardware and technologies. This means that services running on the cloud have less network latency and a greater economy of scale.

Security

Cloud computing makes data backup simple, quick, and less expensive. A business’s data and services can be mirrored across different sites within a cloud provider’s network, so data is never lost and can be recovered in a matter of seconds or minutes.

Types of cloud computing

There are four main categories of cloud computing. Each category in this list builds on the one before it, taking more of the grunt work off of IT staff and outsourcing it to a third-party cloud provider.

Infrastructure as a Service (IaaS)

IaaS is the simplest form of cloud computing. Using IaaS, businesses rent virtual machines, servers, storage, networking, and operating systems from a cloud provider and pay only for the services they use when they use them.

Platform as a Service (PaaS)

PaaS takes cloud computing one step further. In this model, cloud providers supply an environment where programmers can develop, test, deliver, and manage software they create without setting up or managing the underlying infrastructure.

Serverless computing

Serverless computing takes the server model out of the equation. Instead of managing servers that have to run constantly, developers create simple functions using one of many popular programming languages that execute and return data as needed.

Software as a Service (SaaS)

SaaS delivers software applications over the internet, so businesses don’t have to worry about building their own software or installing it on every device. An example of SaaS is Microsoft Office 365, which delivers Microsoft’s complete Office suite through the internet.

Learn cloud computing

Cloud computing has changed the way businesses use technology. Instead of buying their own physical hardware for servers and databases, they rely on third parties to provide these services over the internet.

Instead of building their own platform for developing, testing, delivering, and managing software applications, they use a cloud provider to make it easier. And instead of managing software installations on all of their employee’s devices, they use software that runs on the internet.

If you’re interested in developing software for the cloud, the truth is that not much has changed. The same technologies that ran in a data center still run in a cloud environment.

Learning System Trends 2024

Learning System Trends 2024
  • Any learning system or learning technology or authoring tool – must have a voice narration capability – not just a text-to-audio for the content, but also what I see as a “do this” is the ability for an end-user to move around the system by using their voice. “Open course X.” “Start the recommended playlist’s first course.” “Scroll down and click on the calendar. Click on Tuesday. Click on available time.” “Register me.” No system does this. Sure the majority are ADA508 compliant or similar (I always forget what that is). However, not all of them are, and secondly, when it comes to the voice moving around and taking content within the system – navigation and so on – it’s not there. It should be. It can be if a vendor either built it into their system OR tapped into LAM (which is what takes a gen AI further – which you are unaware of, but it exists and is another AI option. OR tap into machine learning (again AI).
  • When seeing the prompt window on the learner side or admin side, provide your clients with “recommended,” or “top 50 prompt modifiers,” and so on. On top of that, allow someone to say it, and then it is typed in, and they say “click,” and the response shows up. Today, it is all click, click by using your hand.
  • When I hear the vendor say they have AI – I ask them immediately if it is machine learning, gen AI or a combo of both (it can be)
  • If the vendor says combo or they may say it depends on what the capability is – then find out. I can easily spot something and go that machine learning because it looks like it is – so far, I’m 100% accurate (knocks on wood table). I wouldn’t expect you to be unless you see a lot of these or know AI and can spot the difference between the two.
  • I want to know what LLM they are using, or if they say we use multiple, which ones. Is it relevant to you?
  • GPT Turbo, aka GPT 4.5, is the latest version of GPT. It is fee-based. Folks on enterprise with OpenAI, you are using Turbo. There are vendors using 4.5, which is good. The downside? Token fees. Sure, they are low now because, overwhelmingly, the vendors using Gen AI have it on the admin side—create courses/content, identify skills, and create assessments with AI.
  • GPT 3.5 did far better than 3, the freebie of ChatGPT. Folks who were on 3.5 are tapping into 4 (whichever version still has a lower token fee), and others are going into 4.5.
  • OpenAI – the makers of the above LLMs – dominates. It is not even close in our industry. Number two is Azure’s LLM which is built on Open AI’s version.
  • Llama 2 – 100% free open source, which means no token fees. Llama 3 just rolled it and Meta claims it is as good as GPT Turbo. It’s also 100% free open source. Vendors that go this route, take this LLM and do a lot with it. I do know of vendors that tapped into LLama.
  • Google Cloud—Model Garden requires you to use Vertex ML, and then you can select from a variety of Gen AI LLMs.
  • Foundation model – Pretrained multitask large models that can be tuned or customized for specific tasks using Vertex AI Studio, Vertex AI API, and the Vertex AI SDK for Python.
  • Fine Tuneable model – Models that you can fine-tune using a custom notebook or pipeline.
  • Task specific solutions – Most of these prebuilt models are ready to use. Many can be customized using your own data.
  • It requires a lot of computing power – which is why you are seeing small LLMs that can go from a mobile device, with minimal computer power. For the Open AI and others, though, those computers – and the power it is creating a massive carbon footprint – are higher than anything on the cryptocurrency side.
  • To cool the machines down, you use water—a lot of it. Since water is crucial nowadays more so than ever before, yeah, I’d say this is relevant.
  • Create courses/content (I refer to it as a content creator tool, vendors will say authoring tool) – Only one I’ve seen today is robust, whereas an ID person could use it to a point. With synthetic audio, materials too. The rest is headers (I prefer Chapter titles), then pages (they call it something else), and in some cases, content within those items – more often than not, actually. A few have the WYSIWYG window, and in quite a few cases, you can change the text by choosing (professional, witty, serious, and so on). Other vendors use the emoji angle. I wish I could remember what one vendor had as an option with the text change. It was so demeaning, and offensive that I called them out and stated such. I need to go back to my notes and find the vendor, then see if they fixed it. My guess? Nope.
  • Create an assessment with Gen AI. I’ve Seen it a lot. This is the one I hear. You haven’t seen this before, spin. I see a lot of systems, so yeah, I have. Some are better than others.
  • Identify skills that can be presented on the learner side with AI. These skills can be tied to systems that allow the opportunities aspect in their system, or someone uploads their resume, and it takes out key items and lists the skills. I am starting to see vendors tie skills directly with content initially using Gen AI. Equally, I see machine learning with the recommended content/course angle, which looks skewed more often than not due to the algorithm.
  • A couple of vendors are launching or have launched a prompt window on the learner side. The learner can ask questions or statements and the window responds with the answer or supposedly answer. Yes, it can be wrong – hence, always verify before just thinking, “Yeah, this is right, ” and roll on.
  • There is no prompt window either on the admin side or the learner side, whereas if the information that was outputted was wrong, the person can state so and put in the correct retort. AI learns from itself, so if you are not saying this is wrong, then surprise – it assumes it is right. I continue to be stunned that zero vendors are doing this. Every LLM you test out, heck go to the freebie one, has this window.
  • Minimal vendors add the text that the system may output mistakes (a term I see in vendor land) or fake or false information, so review. I’ve seen this text in only a few vendors. As noted, a couple told me they had clients who wanted it removed. That is like saying, “jump out of the airplane, and what? We didn’t teach you how to open it and when. Don’t worry, nothing will happen to you.”
  • The content: The client selects what they want and by what publisher/provider and identifies the number of seats they need (licenses) for that specific content. The seats, by the way, do not have to match all your user base—this content is for this group and only for these folks.  
  • Depending on the vendor, you will see many different third-party providers, minimal, or, yes, I can’t believe I am saying this in 2024: zero.  
  • The plus for you is that you are not required to go to the internet and type in some words, hoping to see what content is ideal for you. Nor should you type this into Gemini (formally known as Bard) or Copilot and similar for search engines. They all scour the web and pull down quite a bit of those worthless top 10s written by someone who has no background in the industry but loves van travel. All of these, those top 10, are affiliates of the vendor. Yes, they make money off you. You will see this with the “we may receive a small commission.” 
  • The benefit is to go to the content marketplace with your vendor and see what content is available based on your use or use cases.   
  • Vendors should consider adding more content providers, especially those that are reliable and can filter out the junk that’s prevalent on the internet. This way, if a client already has a trusted content provider, the integration is already in place, eliminating the need for additional work that may or may not be successful. There are plenty of learning systems out there that have content/course aggregators, such as GO1 and OpenSesame. I often hear that both are the same and have the same publishers. That isn’t the case. There are pros and cons to each of the above. I like OpenSesame (yes, that is the vendor with the built-in AI, and OS will work directly with your client to identify their use cases, and what content is best suited for that). Thus, the idea that you get all this content with a subscription plan – think all you can-eat aspect – is eliminated. OS is one of many vendors that do this. Content Anytime from Cornerstone does, too – but CA is only for Cornerstone clients. OS and GO1 can be used by anybody, regardless of the system. 

I’ll stop at Trend Six. I could easily go into Trend 20. I am holding off because typing with a bruised bone in my wrist is no longer attainable without pain. I guess that is a trend of mine.

Interview prep: Questions you should ask

Interview prep: Questions you should ask

Picture it: You’ve made it to the end of your interview for your dream job. You sailed through your reasons for applying and answered every behavioral and situational question with ease (thanks, STAR method!). You’re down to the final question: “Do you have any questions for me?”

No sweat. You knew they’d ask this question—they always do!—so you came prepared. Not only did you engage your interviewer, but you are also leaving the interview feeling even more confident that this is the career path for you.

So, what did you ask?

Questions to ask at the end of an interview

An interview is an important time to discuss your experience, skills, and interest in a position—but it’s also a conversation. You’re interviewing the company as much as the company is interviewing you.

Asking thoughtful questions during an interview can achieve a lot. For starters, it signals to the hiring manager that you’re a conscientious job-seeker who’s interested in the role. It’s also how you can figure out if you actually want to work there. Just as your interviewer is deciding whether you’ll be a good fit for their company, this is your opportunity to determine whether this company and this role are going to help you achieve your goals.

Think about what you expect this role to be like, if you get it. Are there any gray areas that your interviewer could clarify for you? Some common things to ask about may be:

  • The role and daily responsibilities: “What might a typical day in this role involve?”
  • How your performance will be measured: “How do you measure success?”
  • Future growth opportunities you’d be moving toward: “How do you help employees grow as professionals?”
  • Your potential manager and team structure: “What kind of feedback and support would I receive?”
  • The company culture: “What do you love about working at this company?”

Before an interview, take a moment to write down some questions—around five is a good start, but some people feel more comfortable preparing closer to 10 questions. This way, if any of your questions come up during the interview, you can ask them mid-conversation and still have more on hand to ask at the end of the interview.

As you move through the interview process and get answers to your questions, you might want to ask different interviewers similar questions to compare answers—or find new ones to ask.

Want more questions? Here’s a list of 30 questions to ask and tips for choosing the best questions for your needs.

Keep practicing

Remember: If you’ve made it to the interview, you’ve already demonstrated that you have the skills and experience your interviewer is looking for. Now, it’s time to show your personality. Here are some courses to help guide your interview prep:

With that, our interview series ends. If you have any more questions, feel free to leave them in the comments.

Should College Freshmen Choose Their Roommates?

Should College Freshmen Choose Their Roommates?

Think about a time when you were paired with someone you didn’t know for a group project, a volunteer activity, a room assignment at camp or something similar. What did you learn from and about that person while spending time together? Were there any awkward moments? Did you become friends? Did the experience change you in any way?

If you plan to go to college and live in a dorm, you’ll probably have a roommate, at least for the first year. Would you be open to living with someone you didn’t know? If someone from your hometown, whether a close friend or an acquaintance, were to attend the same school as you, would you ask to room with that person instead of a stranger? Why?

In the Opinion essay “What Is Lost When Freshmen Choose Their Roommates,” Pamela Paul argues that living with a stranger can be good for young people:

For many adults, the first and last time they willingly submit to living with a total stranger is their freshman year of college. And now is the time of year when many kids, just accepted into college, decide they won’t do it.

Cohabitating with anyone in 150 square feet isn’t easy. It’s hard enough to share a room with someone you love. Their intermittent snores, the way they hum while cleaning or just miss the trash can when flinging dirty tissues.

But forcing kids from widely diverging backgrounds, ethnicities and economic classes to live in close quarters is one of the benefits of a residential college. It’s a social leveler. It offers its own education. It can produce terrible conflict, but that, too, is essential to preparing young people for the world. It’s an important part of learning to get along.

Too many students today miss out on that experience altogether. Though in recent years some schools have pulled back from the practice, many have adopted systems that give students far more control over the process. Students have the option of choosing a roommate on their own, whether they connect in person, on social media or through one of many third-party matching services. Or they use a campus matching service like RoomSync or StarRez, which schools can license and tailor to their needs.

While some college administrators say that letting students choose whom they live with allows them to feel more comfortable and safe at school, Ms. Paul argues that it can undermine other values and abilities, such as resilience, risk-taking and navigating differences across identity and ideology:

“College is meant to be a time of life when you step out of your comfort zone and you’re stretched,” says Julie Lythcott-Haims, the author of “Your Turn: How to Be an Adult” and a former dean of first-year students at Stanford. “If people are allowed to choose their own roommates, they’re inherently cutting themselves off from some of the most significant learning available, which is to grow up your freshman year with someone not like you.”

The reality is that when kids choose their own roommates, they tend to go with people who are exactly like themselves. Bruce Sacerdote, an economist at Dartmouth College, has been studying the social effects of college roommates for over a decade. His research points to clear advantages to a randomized process, especially since American campuses still see a lot of homophily or self-segregation by race, ethnicity and class.

“Universities work so hard to achieve diversity, but that’s most valuable if people are actually interacting,” Sacerdote told me. “The most powerful tool universities have to foster that is through roommate matches.”

Kids who pair up are often the ones who went to private or elite public feeder schools where they can easily slot in with mutual friends; they’re also the kids who have resources to meet up over the summer. Letting kids choose their own roommates, Lythcott-Haims said, “privileges the privileged, foments cliques and counters the intended outcome of having a diverse student body in that kids learn and grow because of their interactions with each other.”

Students, read the entire essay and then tell us:

  • Do you think college freshmen should get to choose their roommates? When you weigh the values of comfort, safety and belonging against those of resilience, risk-taking and navigating differences, which are more important for young people to experience in their first year of college? Why?

  • How difficult do you find it to step outside your comfort zone when it comes to getting to know new people and possibly becoming friends with them?

  • Consider the idea that college students choosing their freshman-year roommate “privileges the privileged, foments cliques and counters the intended outcome of having a diverse student body in that kids learn and grow because of their interactions with each other.” Do you agree or disagree? Why?

  • Do you know anyone who went to college and had a roommate? Did the person choose the roommate? What have you been told about that experience? Was it fun? Difficult? A learning experience? What, if anything, would you do differently as a result of hearing that person’s stories?

  • If you’re planning to go to college, do you think you will apply to the same institutions as your friends? What do you think the advantages and disadvantages of that might be? Would you submit a request to live in a dorm room with your friend?

Outsmart Fake News: Protect Yourself From Online Misinformation

Outsmart Fake News: Protect Yourself From Online Misinformation

Discover how to decipher fact from fiction and avoid falling for fake news stories on social media. Spreading false information can be a source of personal embarrassment – as Abraham Lincoln reportedly said, “It’s better to remain silent and be thought a fool than to speak and to remove all doubt.” More seriously, it can also be harmful to society. Examples abound of instances where false stories have had serious consequences, from the rise of measles in the UK following an ungrounded rumour about a childhood vaccine to the serious disorder in the USA following false allegations of election-rigging in the 2021 presidential race.

What Is Fake News?

Fake news can arise through a number of means: 

  • Misinformation such as rumours and false or misleading information which is spread without intent to mislead;
  • Disinformation or fake information that is deliberately spread to mislead the reader; 
  • Malinformation describes facts that are twisted or used out of context to spread hatred or negativity. 

One of the challenges of fake news is the speed with which it spreads. “A lie can travel around the world and back again while the truth is lacing up its boots.” – Mark Twain. The greatest challenge for governments and lawmakers is legislating against malicious or dangerous stories while protecting important freedoms such as free speech and the freedom of the press. 

False Stories That Have Made The News

Fake: Vaccine booster shots increase likelihood of death. Dr. Richard Urso told lawmakers in the state of Tennessee that individuals who received COVID-19 booster shots were more likely to die from coronavirus.

Truth: The Associated Press reported on this fake news and stated that researchers disputed the vaccine claim with verifiable studies that showed the opposite to be true. Some countries introduced legislation to prevent scaremongering about vaccination programmes during the pandemic.

A protester uses a ‘fake news’ poster to demonstrate against a ban on refugees entering the USA in 2017. Photo by Kayla Velasquez on Unsplash.

Fake: Venezuelan migrants deported from Martha’s Vineyard. An Instagram post claimed that 50 migrants had been deported from Martha’s Vineyard in Massachusetts. This “humanitarian crisis” post was widely shared on Facebook

Truth: PolitiFact clarified that a local government or municipality cannot deport any person/s. The group were brought to the mainland for food and shelter as the island did not have the resources to accommodate them.

Fake: Russian media referred to its invasion of Ukraine as a “special military operation” designed to rid Ukraine of Nazis. Coverage, which is government-controlled, majors on Russian victories with little reference to losses.

Truth: What is taking place between Russia and Ukraine is a war with many fatalities on both sides. Reputable news outlets such as BBC Verify have fact-checked the Russian slant on events and pointed out inaccuracies.

How to Spot Fake News

The burden falls on you as the consumer to not only spot fake news but also take responsibility and resist sharing or spreading it further. Here are some ways to ascertain the veracity of any story:

Verify the source. Inspect the web address you’re viewing the article on. A small spelling error may alert you to the truth of the site and what they are reporting. 

Double-check with other sources. Read other reports from reputable media outlets. Has anyone been quoted in the article? Are they an authoritative spokesperson?

Use a fact-checker site

. These carry out vital checks into whether a news story is authentic. Apart from investigating national news stories in their base country, most also look at international headlines around health, climate change etc. This list is far from exhaustive but examples include:

  • Snopes – US entertainment and politics
  • PolitiFact – run by the Poynter Institute, exposes false news stories in the USA with English and Spanish translations
  • FactCheck.org – A Project of The Annenberg Public Policy Center, checks the veracity of stories circulating in the USA
  • FullFact.org – UK-based independent fact checkers
  • AAP FactCheck – Australian-based independent organisation 
  • BBC Verify – UK and international news checker.

BBC Verify examines UK based and international events to provide factually accurate accounts of incidents such as the attack on a Moscow concert hall in March 2024 in which over 100 people were killed. Image from BBC.co.uk

Check images. Images used in fake news articles have been doctored, altered, edited, and manipulated in one way or another. Google’s Reverse Image Search tool allows you to check where various images originate and whether they have been altered.

Is it satire or parody? These types of articles and posts often go over people’s heads and they believe them to be true. Satirical posts are not fake news but exist for comedic value or to make a point.

What to Do if You Spot False Stories

Sometimes it’s enough to ignore fake news – by not passing it on, you are protecting others who may be more gullible. However, if the misinformation is harmful and you know it is false, and especially if it concerns a member of your family, there are a few steps you can take.

  1. Report the content or misinformation using the tools on the relevant platform.
  2. If you or a loved one have mistakenly spread information that you now know to be false, use the same platform to explain your error, if appropriate.
  3. Ensure that the victim of a false rumour has the emotional support they need, particularly if it is a young person. Children’s charities can help in that regard.

How to Avoid Fake News and Be a More Informed Reader

The best weapon against misinformation is factual information. We need to become digitally savvy and learn what we can about media, news, and information. The tool that is used to spread fake news also employs the weapons we can use to fight fake news. That is digital literacy. 

Alison teamed up with Dr Helen Crompton, an international expert in educational technology, on behalf of the Mobiles for Education (mEducation) Alliance to create two courses to help students navigate the internet safely and effectively.

  • The Diploma in Global Digital Literacy is a comprehensive course for new and experienced internet surfers. Covering everything from identifying credible digital content to creating high quality online content, it exposes the negative aspects of the web and explores how to maximise its positive aspects.

Word of the Day: equilibrium

0
Word of the Day: equilibrium

The word equilibrium has appeared in 102 articles on NYTimes.com in the past year, including on April 7 in the Opinion essay “My Faith Forbade Eclipse Gazing. Now It Inspires My Art” by Balarama Heller:

Many ideas in Vedic cosmology (which seeks explanations for both human and nonhuman affairs throughout the universe) depict the physical universe as profoundly animate and vibrant. Some explanations for the mechanics of the observable world mirror modern understandings of concepts like the atom, the cyclic nature of time at scale and quantum mechanics’ “many worlds” theory. But it is still an ancient set of beliefs where planets possess their own personalities, akin to living deities or demons. I am no longer religious, and do not believe in god nor superstition. But growing up, I regarded existence as a grand stage where conflicting energies of chaos and order perpetually and cyclically clash, each vying for supremacy before gradually reconciling and reaching a delicate equilibrium where they coexist in a harmonious, unified balance.

How an MCS grad chose his pathway with Illinois—a top-5 computer science school

Rahul is a recent graduate of the Master of Computer Science (MCS) program from The Grainger College of Engineering at the University of Illinois Urbana-Champaign (Illinois) on Coursera. With U.S. News and World Report naming Illinois’ Department of Computer Science in the top 5 in 2023, Rahul could confidently pick the MCS. Rahul had also earned his bachelor’s degree from The Department of Computer Science and taken machine learning courses on Coursera, so he was sure he could succeed with an Illinois program on the platform. “I knew the quality of the professors. I also knew the recognition and value of the degree in the market,” he says with conviction.

With the MCS, there are two pathways for different interests and goals. You can either select general computer science or data science as your pathway. For Rahul, the decision was clear. “I wanted to go back because the data science component was attractive,” he reveals, adding, “I wanted to catch up on all the new technologies since my undergrad.” Having been in his computer science career for approximately two decades, including tenures at both small and big companies, he also knew he wanted to gain additional experience in the ever-changing field. Ultimately, he says, “I wanted to land a job that would allow me to build on my previous work experience.”

Rahul earned his bachelor’s degree in computer science on campus at Illinois. However, when he returned for his master’s degree, he knew the online program would be the best fit for his family’s work-life balance. He notes, “The online program is not much different than being on campus. You get the interaction with instructors and peers, and the flexibility worked really well for my schedule.”

In addition to the fact that it supported his lifestyle, Rahul saw other benefits to learning on Coursera. “The tuition wasn’t as expensive, and I wanted that TA support,” he remembers, while also mentioning, “We had a Slack channel. It was a helpful resource to be able to network with other students and also get questions answered. It’s very much a collaborative program.”

Having graduated with his MCS in the spring of 2023, Rahul has now had the opportunity to reflect on his time in the program and appreciate the impact he’s made on his career by earning his master’s degree. He proudly states, “I got a job in Hollywood because of the knowledge I picked up in one of the courses. It very much qualified me for my role.” Rahul also has this advice for others who are considering the MCS: “It’s good to understand your WHY when you’re applying to the program. It’s going to be work, but it’ll also be rewarding.”

Rahul’s story shows us how you can learn on your terms with Coursera and earn a computer science degree with Illinois—whether that’s through the general computer science or data science pathway. If you’re thinking about a career in computer science, check out the Master of Computer Science from The Grainger College of Engineering at the University of Illinois Urbana-Champaign today and learn more about the two pathways you can take.

What Should Be Done About the Gender Pay Gap in Sports?

In “Biden Weighs in on Caitlin Clark Salary Debate After W.N.B.A. Draft,” Neil Vigdor writes about the reaction to Clark’s contract:

President Biden jumped into a debate about gender and sports this week, calling for pay equity for women athletes after Caitlin Clark, the University of Iowa basketball standout, was selected first in the W.N.B.A. Draft.

Ms. Clark’s salary will be far less than that of her male counterparts. Mr. Biden, writing on X on Tuesday, said that for all their accomplishments in sports, women athletes were undervalued.

“Right now we’re seeing that even if you’re the best, women are not paid their fair share,” he said. “It’s time that we give our daughters the same opportunities as our sons and ensure women are paid what they deserve.”

Mr. Biden was nodding to a banner moment for women’s basketball, one powered by stars like Ms. Clark, who was chosen by the W.N.B.A.’s Indiana Fever, and Paige Bueckers of the University of Connecticut and Angel Reese of L.S.U.

But Ms. Clark’s salary will amount to $338,056 over the next four years, under the W.N.B.A.’s collective bargaining agreement. The total is a fraction of the contract of Victor Wembanyama, whom the San Antonio Spurs chose with the top pick in last year’s N.B.A. Draft. His contract was for $55 million, according to Spotrac, a website that tracks salaries in sports.

The disparity has drawn intense scrutiny during a pivotal moment for sports, particularly in college athletics. Students have gained the opportunity to monetize their athletic success through name, image and likeness, or N.I.L. deals, that can earn top stars like Ms. Clark millions of dollars. But the overall compensation of women in sports is far outpaced by how much money male athletes make.

The women’s national championship game, in which Ms. Clark’s Iowa lost to South Carolina, earned higher ratings for the first time than the men’s championship contest between UConn and Purdue.

In a related piece, “The Big Number: $76,535,” Marie Solis takes a closer look at the economics of why Clark will be paid so little as a player for the Indiana Fever compared with what her male counterparts in the N.B.A. make:

The longstanding disparity between the men’s and women’s teams has to do with the leagues’ finances.

The pot of money for players’ salaries is based on a percentage of revenue: While the N.B.A. generates annual revenue of about $10 billion, the W.N.B.A. pulls in about $200 million a year, and the men get a larger percentage of their league’s revenue than the women do.

But that could change, in part because of Clark. Sales of Clark’s Fever jersey at Fanatics, the digital sportswear retailer, broke its draft-night record for any draft pick in any sport. She also drew millions more viewers to ESPN’s coverage of the draft, and teams are anticipating a spike in ticket sales to W.N.B.A. games.

Clark is also likely to have other sources of income. She is nearing a $20 million deal with Nike, according to The Athletic.

Students, read the entire article and then tell us:

  • What is your reaction to Clark’s rookie contract with the Indiana Fever? Do you think it’s fair that her four-year salary of $338,056 is a small fraction of Wembanyama’s $55 million contract?

  • On the social media platform X, Biden said: “Right now we’re seeing that even if you’re the best, women are not paid their fair share. It’s time that we give our daughters the same opportunities as our sons and ensure women are paid what they deserve.” Do you agree? What message does the salary disparity between Clark and Wembanyama send to female athletes — and to the young women aspiring to play professionally one day?

  • Solis points out that the N.B.A. generates an annual revenue of about $10 billion, while the W.N.B.A. pulls in about $200 million a year. Is the gender pay gap simply a reflection of economics? Or do you think other factors are at play, too?

  • What do you think should be done about the gender pay gap in professional basketball and in all sports? What can sports leagues and governing bodies, colleges and universities, media companies and fans do to make sure that female athletes receive the respect and pay they deserve in our society?

  • Are you a Clark fan? Will you be following her and the W.N.B.A. when the season starts on May 14? Do you think Clark will continue to excel on the court and draw soaring ticket sales and television ratings in the W.N.B.A., as she did in college?
