Remembering the end of support for VRML in Internet Explorer

by Raymond Chen

I was cleaning out some old documents and found an email from 1999 on some changes to Internet Explorer. Most of it is boring, but I found this part interesting:

VRML is being removed from IE5.5 and will only be available on Windows Update. The company that supplied the component cancelled the project¹ (and at that point they were the only VRML viewer supplier, after acquiring everyone else)², and we were not getting any fixes.

(Footnotes mine.)

That’s kind of sad. All of the VRML companies get eaten up by a big fish, and then the big fish gives up on VRML.

Bonus chatter: For many years, I kept a large display board that was presumably created for some industry event. The gist of the message on the board was that Internet Explorer was committed to supporting VRML and the VRML community.³

I printed out a copy of this email and taped it to the display board.

When Internet Explorer announced its commitment to VRML and the VRML community, they hadn’t anticipated that the company that makes the product at the center of the VRML community would itself abandon its commitment to VRML.

¹ VRML looks to open source: “After an internal shake-up, 3D browser and tools owner Platinum Technologies plans to turn over its source code.”

² VRML Consortium changs Name to Web3D Consortium: “Platinum Technology, which now owns a significant slice of the VRML developer community, having acquired InterVista Software and Cosmo Software over the course of the year…”

³ This gives off strong “My ‘not going to abandon VRML’ sign has people asking a lot of questions already answered by my sign” vibes. I can only assume that the sign was created to quash rumors that Internet Explorer was going to abandon VRML. Which it didn’t. VRML abandoned VRML.

my employee dropped the ball while I was away, my husband’s boss is coming on to him, and more

by Ask a Manager

It’s five answers to five questions. Here we go…

1. My employee dropped the ball on something major while I was away

I am the executive director of a small charity. I had the opportunity to support my mom on a three-week holiday in Europe, all expenses paid. My organization had six months notice and I usually end the year not using any vacation time. So no questions or concerns about being away. I brought all the tools to stay in touch with the team.

Unfortunately my go-to staffer who was slated to take on three major fundraising events during that time got sick the first week and had to cancel our participation in two of the three events.

I’m totally gutted and frustrated this happened. This staff person doesn’t like relying in volunteers too much as they can be fickle and high maintenance, so there was no back-up and she didn’t let me know soon enough for me to rally my contacts (I’ve been with the org 21 years, she three) to call in a favor or three.

My feedback in the moment was agreement and compassion as she was genuinely under the weather. But our absence from these events is not without consequences.

How do I coach her that we need more depth of support without making her feel like she failed me or the organization? She doesn’t do well with criticism. I want to be honest with her that relying on just herself or her circle of friends for volunteers is risky for this reason. I also want her to know the importance of the relationships with the people we bailed on. Any advice on how to acknowledge the negative consequences in a kind and teachable way?

The basic framing you want is: “I understand how it unfolded the way it did, but let’s talk about things we can do to make sure it doesn’t in the future, like XYZ.”

Also, you probably needed to be more proactive about addressing her reluctance to use volunteers before this ever happened. It sounds like you saw it was an issue but didn’t really dig into it with her, and there’s likely a lesson here about the need to bring concerns like that to the surface and work through them before they cause a major problem … as well as maybe to do more hands-on game-planning for major events, especially if you’ll be away when they’re happening, like talking through things that could go wrong and how to handle them so your staff is aligned with you about what to do even if you’re not on-site.

Any chance that her “not doing do well with criticism” has led you to avoid giving her feedback or direction in the past when you really needed to? That’s something to dig into, too, if so.

2. I was asked to provide proof that I wasn’t involved with my husband’s death

I woke up next to my husband in May and found he was dead. I am a teacher in training and the university I go to is well aware of the situation. I have a tattoo on my neck which is the last message he wrote to me, and one day a colleague at work said, “Do you have your name on your neck?” I explained the situation.

Last Friday I was pulled into a room by myself with no warning and asked if I had a letter from the police clearing me of his death. I was told I had overshared at work, and due to the nature of the death (he was only 49 and died unexpectedly) they would like to see a letter from the police clearing me of any wrongdoing. I became extremely upset, and told her I wouldn’t go any further than this unless HR was there to document the conversation and take notes. She then followed me into the car park and asked me not to leave as she “didn’t want me to leave like this.” I told her I was too upset to talk and she still asked me to stay.

I’m only three weeks into my course and am terrified they will look for any reason to throw me off. Am I making a mountain out of a molehill?

They asked you for a letter from the police clearing you of involvement in your husband’s death? No, you are not making a mountain of a molehill. That’s incredible offensive and upsetting.

I don’t know who the person was who pulled you into a room for this conversation, but I’d bet they were acting on their own and without consulting anyone above them, because that is a fully bananapants thing to do. You should talk with someone above her immediately and/or HR: report what happened and ask if this is actually something they need and whether the person who demanded it of you was speaking for the organization in doing so. It’s highly, highly likely that they weren’t and that whoever you talk to will be horrified and handle it on your behalf.

3. My husband’s boss is coming on to him

My husband’s supervisor is a woman, and she is coming on to him at work. I’m afraid they’re going to have an affair. Should I confront her or what should I do?

No, you should not confront her. You should talk to your husband, the person you’re in the relationship with.

4. I feel guilty about interviewing for a private sector job

I work for a government agency that is routinely rated as popular by American citizens. It is also small and almost always operates on a shoestring budget. With the shutdown and the secretary announcing further RIFs, I applied to a few other positions.

One got back to me right away and I interviewed this morning. It sounds exciting and I love the mission … but I’m deeply sad about it. I’ve worked for my agency for 20 years, I hope to continue, but also feel I can’t keep subjecting myself and my family to the “will I have a job tomorrow?” yo-yo that’s been going on for months.

Is this normal? It’s “just” a job. But apparently one that doesn’t want me anymore? I know any job doesn’t have loyalty to you, but I feel deep down I’m being disloyal.

You’re not being disloyal. Public service doesn’t require that you commit to a lifetime of servitude to the public or to your agency; it requires that you commit to doing a good job while you are there, for however long you decide that will be. You are not an indentured servant, and you are not required to remain in a job that is no longer serving your or your family’s interests.

That is always true, of all jobs. But public service jobs can have an additional layer of feeling you’ve entered into a sort of covenant with The People. Unfortunately, though, your employer has broken that covenant with you, rather violently. There is no particular obligation on your side to pretend that covenant looks today like what it used to look like.

5. Explaining I’m job searching because I’m worried my team may be laid off

I have good reason to suspect that my entire team will be laid off this year. Ideally, I’d like to stay at my company a while longer, but with the state of the job market as-is (I’m near D.C.) I get nervous about waiting to search until I’m already out of income. If I start now, though, what would I say about why I’m looking for a job when the answer is entirely just job insecurity?

If you’ve been there at least a couple of years, you can just focus on why you’re interested in the new job and not why you want to leave the old job. But if you haven’t been there long enough to make that a workable answer, it’s fine to say, “I’m seeing some indicators that the company is likely to need to make some cuts later this year, and I’m looking for a role with more stability.”

updates: employee gets special privileges because she’s dating an NBA player, and more

by Ask a Manager

Here are three updates from past letter-writers.

1. Employee gets special privileges because she’s dating an NBA player

I didn’t have time to go to my manager regarding your advice because days after your response was posted, Cersei’s boyfriend broke up with her. As a side note, she lived with him in his very nice house. So I imagine it was a very painful breakup and was further complicated by the logistics of having to move out.

Morale has slightly lifted but not by much because of the anticipation that special treatment for Cersei will manifest in a different way. It certainly leaves a bad taste in your mouth to know that her summer WFH status stopped because her relationship imploded, not because the executives realized how unfair it was.

A week ago, I discussed with my boss that we almost lost three people because of this. I mentioned that we need to avoid this happening in the future, with Cersei or anyone else, and with WFH or anything else that could be deemed as special treatment. He agreed it was in poor taste of the executive team, but didn’t think much could be done. Unfortunately, companies like mine don’t care about high turnover. Losing seasoned employees doesn’t faze them one bit. They just shrug their shoulders and attempt to hire replacements as quickly as possible. I am currently planning my exit. As you can imagine, this is one of several issues at my workplace.

To clear up some confusion from the comment section — pro athletes have a couple months off during the summer. Since her boyfriend is not from the city of his NBA team, he would often go to his hometown during his time off. Cersei was granted the ability to WFH so she could travel with him during this time.

2. Can I learn to thrive under a hyper-critical boss?

First of all, thank you so much for responding to my letter so quickly. I was really in the pits of despair. I took screenshots of a number of the comments and used them as (sometimes daily) reminders. Some things that really helped, based on commenter suggestions:
– focused on “my best work” instead of “make Jane happy”
– changed my delivery method to Jane — I looked at how she communicated to her boss and copied that
– continuous reminders to myself that this is a Jane problem, not a me problem, which helped me to separate her extreme criticism from my actual performance

Things also improved in part because once the division grew, her intensity was spread out over more people, projects and funders. From my vantage point, her style is the same, and it definitely impacts those around her.

When Jane became too busy to micromanage me, things got so much better. The work remained rigorous and complex, and I can now look back on the past few years and see a clear upward trajectory in my skills and level of responsibility, even if that responsibility was begrudgingly given.

I am very aware that I have picked up on some of Jane’s style, and am continually monitoring myself to make sure I’m not sacrificing kindness and flexibility for efficiency or “being right.”

Thanks again to Alison and all of the commenters. I read this blog regularly and recommend it to anyone I come across with work questions or struggles. It has helped me through so many workplace interactions that require leadership, compassion, communication and consistency.

3. Quitting my job while my manager is on vacation (#5 at the link)

Turns out you were right, I did get the offer and it did take longer than expected (it was three weeks after I sent that question!), so the timing worked out fine after all. That’s good, since my boss’s boss was also on vacation, and I would’ve felt a little silly going higher up than that! But it’s good to know most reasonable places are going to also be reasonably flexible about when I can give an answer.

I’m on my second week at the new place, and it’s better than my old job in every way imaginable. I used a ton of your advice to help me through the entire interview process, so thank you again for everything you do! It’s much appreciated.

it takes me longer to do my work — why can’t I opt out of overtime pay?

by Ask a Manager

A reader writes:

I have worked in the evolving field of IT all of my four-decade career. Most of my jobs have been exempt from overtime, while my last few tech support / help desk positions have been non-exempt. I’ve always been a slower (and I think, more thorough) worker who needs more time to get my work done and who has no problem working late, even most evenings, to get the job done.

This has been fine in my exempt positions, as I’ve had freedom to work as many hours as I want / need, and supervisors have mostly been quite pleased with my work. In my first couple of non-exempt roles, I would still work longer hours but leave the hours beyond 40 off of my time sheets, unless management had requested something special — and this worked out well, too.

However, in my last non-exempt role, it came to my supervisor’s attention that I was working more than 40 hours a week, and he told me that this must stop. I countered that I don’t mind doing it, and since I leave the extra hours off my time sheet, it doesn’t cost the company anything. But he said I could not do that any longer, as it was a misrepresentation, and that overtime pay would not be approved.

Consequently, I started completing fewer tasks each day and was placed on a performance improvement plan where the main focus was to improve my time management and multi-tasking ability. I was able to make some improvement, but it was deemed insufficient and I was terminated for not meeting the job requirements.

I understand that the letter of the law means that all hours over 40 in one week must be paid at time and a half for non-exempt positions, but many employers will not approve it or might approve for a couple of extra hours but not more, and then look the other way for employees who need more time to complete their work and so leave the rest off their time sheets. Honestly, I’d rather work the extra hours without additional pay, which I did all the time when I was in exempt positions, than be terminated for not meeting job requirements.

So in some cases such as this, I believe the overtime labor laws can be unfair, and that workers should have the right to opt out. What do you think of this?

The problem is that if you give workers the right to opt out from overtime pay requirements, you’ll immediately have situations where they’re pressured to do that by their employers.

In your case, it sounds as if you’d genuinely choose to opt out via your own free will, but many, many people would not and would still end up pressured by their employers to do it anyway. And the more in need of paying work someone is, the more vulnerable they’re likely to be to that pressure.

That’s why the law doesn’t make it optional. And that’s why any responsible employer needs to do what your last one did and tell you that you can’t work unauthorized overtime even if you don’t mind it. They’re still liable for paying you for those hours, even if you try to explicitly excuse them from it. Legally, they’re required to pay you the overtime whether you want it or not … and they could end up paying fines and penalties down the road if they don’t.

In your situation, it sounds like you are really well-suited for exempt positions where you can work additional hours without it triggering mandatory overtime pay, and those are the positions you should look for.

Precision is important but not if clarity matters

by Matthew (@MCeeP)

Like most young overenthusiastic naive academics, my first academic paper was rejected.

It was a good paper (I thought), it covered the work well and was an important set of results to share with the wider community… the key components of an academic paper. Astonishingly, the reviewers actually agreed on all of those points, which I would have thought was enough to get my paper published (see note about being naive). However, of my two reviewers, one marked it “not suitable for publication” which torpedoed the paper. The reason they gave was:

“This paper is too descriptively written and lacks the academic complexity I’d expect”

So my science was good, the results were great, but it can’t be published because it’s too easy to read? Yikes, what a start to the world of academic paper writing… and some amazing foreshadowing of a side career in science communication.

It’s also a strange admissions from the reviewer that readability is not something they expect, nor I assume, something they work towards. I’ve read a lot of academic papers and I can absolutely see that writing in a way that is readable was probably quite far down most authors priorities list which is a shame as I think that an academic paper writing style should be readable (crazy stuff).

When it comes to writing style a paper should be two things, precise and clear. It is sometimes a misconception too much of the second weakens the first. In reality, both are equally important, and all too much people shy away from the clarity to avoid it exposing their weakness in the precision.

The trick is finding a balance between the two.

As anyone teaching academic writing will tell you that you need to understand your audience. Academic papers are for a similarly skilled peer-audience and should be written as such. But, writing for someone similarly skilled does not mean that it should be overly complex, or filled with needlessly impenetrable language aimed at making it vociferously difficult to cognitively assimilate the conceptual core of.

Some complex language is unavoidable and important, particularly for scientific terms. However, the language you use around those terms doesn’t need to feel like you stapled a thesaurus to your paper. The general complexity of scientific terms if anything demands simpler wording around it to allow it any hope of making a jot of sense to anyone.

Thanks to imposter syndrome, we are all prone to believing that all of our peer-audience are secret super genius that will soon discover that we are in fact a dumb dumb. However, in reality we’re all dumb dumbs in our own very particular ways and often need a lot more help understanding stuff than we ever want to admit. So the best place to start is that your audience are probably just like you and would be quite happy with a little extra explanation, and it’s okay to give it to them.

I am being precise in my wording here, extra explanation, not simplified.

You don’t want to avoid using scientific terms, as they are often highly specific and exist for an important reason. Simplifying your explanations is likely to end up removing information that may be key to repeating or properly analysing your work. Instead, focus on using 5-6 extra words to add additional explanation or context to that term can make your paper far more readable.

I will forever consider my first rejection a badge of honour. I’m very pleased to have started at with my academic papers being too focused on description and clarity. As a young academic, I took one look at that feedback and decided that was absolutely the kind of academic I wanted to be.

Slipknot Travels To India To Begin Psychedelic, Free-Love Phase Of Career

by The Onion Staff

RISHIKESH, INDIA—In an effort to break down creative barriers and open their minds to new types of spirituality, members of the heavy metal band Slipknot reportedly traveled to India this week to begin the psychedelic, free-love phase of their career. “The rishi has been teaching us a lot of different things about pain and anger, and now, thanks to his teachings, we’re all about abundant love and universal acceptance,” said percussionist and Slipknot co-founder Shawn Crahan, sitting cross-legged on the floor and clad in a lightweight beige tunic as he extolled the virtues of discipline, simplicity, and mindfulness enshrined at the ashram that he and his fellow bandmates—known for the songs “Eyeless,” “Wait And Bleed,” and “People = Shit”—had recently made their home. “We learned all about Transcendental Meditation and realized that we need to expand our collective consciousness. Only then can we shed our masks—both physical and spiritual—and truly grow as artists.” Slipknot has also teased plans for an all-sitar set at Knotfest later this year.

U.S. Military Carries Out Strike On Scuffy The Tugboat

by The Onion Staff

ARLINGTON, VA—Saying the Pentagon had acted swiftly on an insider tip about the vessel having a “big adventure” planned, Defense Secretary Pete Hegseth confirmed Tuesday that the U.S. military had carried out a strike on Scuffy the Tugboat. “Little Scuffy wasn’t content with merely floating around in the bathtub, so he made for the nearest river and quickly rose through the ranks of violent Venezuelan drug cartels to become a militarized narco-trafficking vessel,” said Hegseth, adding that Scuffy’s close ally, the man with the polka-dot tie, was clearly in league with President Nicolás Maduro. “This wasn’t just a toy tugboat—this was an enemy combatant tugboat that needed to be taken out for the safety of U.S. citizens. Just look at Scuffy’s big, soulless eyes. He was clearly high and carrying a great heavy load of dangerous fentanyl intended to kill your sons and daughters. We fired several warning shots at Scuffy, and he threatened us by saying, ‘Toot, toot,’ so we blasted that small but mighty tugboat with a blue smokestack right out of the water.” Hegseth confirmed the military was also investigating drug trafficking by train and would not hesitate to blow up the Little Engine That Could.

Hi, I’m an Early 2010s Tech CEO

by BD Barone

I wear the same T-shirt every day, and I have a relatably unkempt haircut. I remind you of the smart kids from high school, so I give you hope that the future might be okay.

My company has a slogan like “Connect Everyone” or “Build Beautiful Stuff,” and I promise you that we’ll never quietly change that to something more morally ambiguous like “Do the Right Thing.”

I’m about your age. Maybe a little older. People our age are chill and socially engaged, so I support things like civil rights, access to education, and medical research. You could never imagine me sitting in the front row at the inauguration of a far-right ruler who promised to destroy those things.

Because I dropped out of Stanford to start this company, you know for sure that it’s my life’s work. I’ll always be at the helm, so the idea that I’ll hand over the company to an ex-McKinsey consultant and retire to a Hawaiian compound built on cleared forest is preposterous.

I’m an engineer, so I have an objective, scientific view of the world. Everything I do is thought out and logical, and it means I won’t ever have the desire to surround myself with MBAs and yes-men who let me win at Catan.

Maybe they’ve made a movie about me already. In it, I come across as a passionate, smart, wide-eyed kid, and the worst thing it portrays me as doing is some light backstabbing. “Startups seem fun and exciting,” you’ll think. If I told you I would eventually focus my platform on giving Nazis a place to share their real-time thoughts on Disney movies, you wouldn’t believe it.

People fell in love with my product because it helped them do something useful, like connect with friends or store photos online for free. You believe my company will always stay true to you, the user, and that I won’t get distracted by fads or trends that boost my stock price.

Yes, you, my beloved user, are who has made me fabulously rich. You tolerate ads duct-taped to every surface of my app and have no reason to think I will eventually try to monetize you further by convincing you to strap data-harvesting cameras to your face.

I’m an early 2010s tech CEO. I care about the world. I care about you. And I promise you that the future is safe in my hands.

An Illustrated Introduction to Linear Algebra

by Aditya Bhargava

This post assumes you know algebra, but no linear algebra. Lets dive in.

There are two big ideas I want to introduce in the first chapter: Gaussian elimination, (which is not strictly a linear algebra thing, and has been around for years before linear algebra came along), and row picture versus column picture, which is a linear algebra thing.

Money example

Let’s say you have a bunch of nickels and pennies, and you want to know how many of each do you need to have 23 cents.

You could write that as an equation that looks like this:

x is the number of nickels you need, y is the number of pennies you need. And you need to figure out the x and y values that would make the left-hand side work out to 23. And this one is pretty easy, you can just work it out yourself. You’d need four nickels and three pennies.

So x is four, y is three.

This kind of equation is called a linear equation. And that’s because when you plot this equation, everything is flat and smooth. There are no curves or holes. There isn’t a ^2 in the equation for example to make it curved. Linear equations are great because they’re much easier to work with than curved equations.

Aside: Another solution for the above is 23 pennies. Or -4 nickels + 43 pennies.

The point is you have two variables (x and y for nickels and pennies), and you are trying to combine them in different ways to hit one number. The trouble starts when you have two variables, and you need to combine them in different ways to hit two different numbers. That’s when Gaussian elimination comes in. In what world would you have to hit two different numbers? Does that seem outlandish? It’s actually very common! Read on for an example.

Food example

Now let’s look at a different example. In the last one we were trying to make 23 cents with nickels and pennies. Here we have two foods. One is milk, the other is bread. They both have some macros in terms of carbs and protein:

and now we want to figure out how many of each we need to eat to hit this target of 5 carbs and 7 protein.

This is a very similar question to the one we just asked with nickels and pennies, except instead of one equation, we have two equations:

Again we have an x and a y. Lets find their values. To solve these kinds of questions, we usually use Gaussian elimination. If you’ve never used Gaussian elimination, strap in.

Gaussian elimination

Step one is to rewrite this as a set of two equations:

Now you subtract multiples of one equation from another to try to narrow down the value of one variable. Lets double that second equation:

See how we have a +2y and a -2y now? Now we can add the two equations together to eliminate y:

We’re left with one equation and one variable. We can solve for x:

Aha, we know x = 3. Now we can plug that into one of the equations to find y.

We plug that in to one of the equations and find out that y equals 1, and there we have answer: three milks, one bread, is what we need.

This method is called Gaussian elimination, even though it was not discovered by Gauss. If you haven’t seen Gaussian elimination, congratulations, you learned a big idea! Gaussian elimination is something we will talk about more. It’s part of what makes linear algebra useful.

We can also find the solution by drawing pictures. Let’s see how that works.

Picture version

Let’s plot one of these lines. First, we need to rewrite the equations in terms of x.

Reminder: first equation is for carbs, second for protein. x is number of milks, y is number of breads.

Now let’s plot the graph for the first equation.

Now, what does this line represent?

It’s all the combinations of bread and milk that you can have to get exactly five carbs:

So you can eat no milk and two-and-a-half breads, or two milks and one-and-a-half breads, or five milks and no bread, to get to exactly five carbs. All of those combinations would mean you have eaten exactly five carbs. You can pick any point that sits on this line to get to your goal of eating five carbs.

Note: You can see the line goes into the negative as well. Technically, 5 breads and -5 milks will give you 5 carbs as well, but you can’t drink negative milks. For these examples, let’s assume only positive numbers for the variables.

Now, let’s plot the other one. This is the same thing, but for protein.

If you eat any of these combinations, you’ll have met the protein goal:

You can pick a point that sits on the first line to meet the carb goal. You can pick a point that sits on the second line to meet the protein goal. But you need a point that sits on both lines to hit both goals.

How would a point sit on both lines? Well, it would be where the lines cross. Since these are straight lines, the lines cross only once, which makes sense because there’s only a single milk and bread combo that would get you to exactly five grams of carbs and seven grams of protein.

Now we plot the lines together, see where they intersect, and that’s our answer:

Bam! We just found the solution using pictures.

So that’s a quick intro to Gaussian elimination. But you don’t need linear algebra to do Gaussian elimination. This is a technique that has been around for 2,000 years. It was discovered in Asia, it was rediscovered in Europe, I think in the 1600s or something, and no one was really talking about “linear algebra”. This trick is just very useful.

That’s the first big idea you learned. You can stop there if you want. You can practice doing this sort of elimination. It’s a very common and useful thing.

The column picture

What we just saw is called the “row picture”. Now I want to show you the column picture. I’m going to introduce a new idea, which is: instead of writing this series of equations, what if we write just one equation? Remember how we had one equation for the nickels and pennies question?

What if we write one like that for food? Not a system of equations, just a single equation? What do you think that would look like? Something like this:

It’s an equation where the coefficients aren’t numbers, they’re an “array” of numbers. The big idea here is: what if we have a linear equation, but instead of numbers, we have arrays of numbers? What if we treat [1 2], the way we treat a number?

Can that actually work? If so, it is pretty revolutionary. Our whole lives we have been looking at just numbers, and now we’re saying, what if we look at arrays of numbers instead?

Let’s see how it could work in our food example. What if the coefficients are an array of numbers? Well, this way of thinking is actually kind of intuitive. You might find it even more intuitive than the system of equations version.

Tips For Making Friends As An Adult

by The Onion Staff

While it’s natural for personal relationships to change or fade over time, many adults reportedly find it difficult to forge new friendships later in life. The Onion shares tips for making friends as an adult.

Start calling your parents by their first names.

Find a volunteer cause you can immediately dispense with the second your social life picks up.

Hang out at the playground where you made your first friend as a kid—sometimes lightning does strike twice.

End any outstanding East Coast vs. West Coast rap beefs.

Reconnect with old friends to see if they know anyone better they can introduce you to.

Establish authentic connections by standing in a long line and complaining to the people around you about how long it is.

Threaten to turn in the rest of your heist crew if they don’t hang out with you after the job.

Adopting an iguana can be a great way to meet people at the local iguana park.

Carefully observe someone who has a lot of friends, then kill and replace them.

Travis Kelce Gets Cold Feet After Listening To New Taylor Swift Album

by The Onion Staff

LEAWOOD, KS—Seeing his fiancée in a whole new light, Kansas City Chiefs tight end Travis Kelce was reportedly getting cold feet Monday after listening to Taylor Swift’s The Life Of A Showgirl. “It’s kind of weird I’ve only known her for two years, don’t you think?” said the Kansas City Chiefs tight end, who told his teammates he had begun experiencing completely new uncertainties about his relationship with the pop star ever since listening to her sing the words “We all dressed up as wolves and we looked fire” and “Did you girlboss too close to the sun?” on the latest record. “I know people get engaged after less time, but still. Am I rushing into it? I just feel like the Taylor I knew wouldn’t have written ‘Wi$h Li$t.’ Maybe I should suggest we spend a little time apart. Some time with Jack Antonoff might do her good.” At press time, sources confirmed Kelce and Swift were in a blow-up fight after she walked in on him listening to Brat.

Nobel Prize In Medicine Awarded To Tums 

by The Onion Staff

STOCKHOLM—In an effort to honor the groundbreaking work of bringing fast relief to millions suffering post-meal heartburn and indigestion, the prestigious Nobel Prize in Medicine was awarded Monday to the over-the-counter chewable antacid Tums. “What Tums has achieved was long thought impossible: a fruit-flavored tablet capable of quickly neutralizing acid reflux even after a person has eaten dozens of jalapeño poppers,” said Olle Kämpe, chair of the Nobel Prize Committee for Physiology or Medicine, adding that the panel was particularly impressed by the scientific rigor behind Tums’ catchy jingle and its pioneering development of colorful little miracle tablets. “How often have we been unduly punished by our own bodies for having one too many chili dogs? How many generations have accepted that bloating is the inevitable price of enjoying a greasy bacon double cheeseburger? Tums allows our children to grow up in a world where they can house two dozen Buffalo wings without the consequence of an upset stomach.” At press time, Tums had also been awarded the James Beard Award for Excellence in Tropical Flavoring.

Tarot Readings for Life in the Big, Soul-Crushing City

by Anne Marie Wonder

Life in the big city can be many things. But mostly it is hard, expensive, and exhausting. Occasionally, it can smell like poop. Above all, it is confounding. So, when the city seems to be throwing all kinds of confusing omens and symbols your way, why not turn to a little divination to see what the city is really trying to tell you?

- - -

THE SUBWAY LOVERS

Two young lovers make out, unashamed, while others watch in horror, disgust, and morbid curiosity.

UPRIGHT: Lust, passion, desire.
REVERSED: Seriously, get a room. This is a C train at rush hour.

- - -

THE APARTMENT HERMIT

The apartment hermit emerges timidly from his domicile. In his right hand is a food delivery bag. On his face is an expression that reads, “How did this all cost thirty-eight dollars plus tip?”

UPRIGHT: Refuge, comfort, solitude.
REVERSED: Congrats, you are now the Weird Roommate.

- - -

THE PIZZA WHEEL OF FORTUNE

Above the city against a bright blue sky, a giant glistening wheel of pizza shines. Each piece of the pie represents a different slice of pizza, symbolizing the ever-changing fortunes of life in this city.

UPRIGHT: Variety, zestfulness, optimism that you will find a dollar slice soon.
REVERSED: You chose to wait in line for a mediocre pizza alongside everyone else who saw it on TikTok.

- - -

THE RAT KING

A large rat, wearing a coat made of smaller rats, looks over his shoulder as he scurries toward his subway lair. Above his head is a crown, at his feet is… possibly a bottle of pee? Yeah, that’s definitely pee.

UPRIGHT: Manifesting into reality, asserting one’s truth
REVERSED: Literally nobody believes in you.

- - -

THE OUT-OF-TOWNER

A young woman is dazzled by the sights and sounds (specifically between Thirty-Fourth and Fifty-Ninth Streets) as she joyfully steps off the curb while livestreaming for her twelve followers.

UPRIGHT: Unbridled Midwestern joie de vivre, a pitstop at the M&M store.
REVERSED: This city will destroy you.

- - -

THE TRAIN

An underfunded public transit train is either entering or leaving a station, depending on your perspective. It is moving at a glacial pace either way, but it technically is moving.

UPRIGHT: Tenacity, overcoming conflicts, forward movement toward a goal.
REVERSED: Your next train will be arriving in thirty-two minutes.

- - -

TRUMP TOWER

Ugh.

UPRIGHT: Nope!
REVERSED: Yep, still bad!

- - -

THE LADY OF LIBERTY

The Lady of Liberty sits on her pedestal, with a resigned expression on her face. She still holds her torch up high in the face of adversity, however. Things have just been tough lately, okay? She just needs a minute to sit down. Be cool.

UPRIGHT: Equity, righteousness, and justice for all!!!
REVERSED: Why so many Australians everywhere?

- - -

THE QUEEN OF CUPS

The Queen of Cups sits with a buzzing, palpable energy, surrounded by empty coffee cups. Her expression could be one of excitement, perhaps due to the manic level of caffeine coursing through her bloodstream.

UPRIGHT: Electricity, action, synapses firing on all cylinders.
REVERSED: Your morning latte cost nine dollars.

- - -

NINE OF PIGEONS

A young man reads in the park while arguably too many pigeons gather above him. Does this qualify as a flock of pigeons? A flight of pigeons? A litter of pigeons?

UPRIGHT: No, seriously, what do we call this many pigeons?
REVERSED: A murder of pigeons.

Aliens in Athens

by Corey Mohler
PERSON: "In the year 470 b.c. an alien spacecraft landed on Earth, to investigate if humans were intelligent enough for contact. "

PERSON: "They disguised themselves as a human and asked to meet with the smartest human, and the people brought him before Socrates."

PERSON: "Tell me, Socrates, how do humans reason?"

PERSON: "Well, i believe that we reason best through an open dialect."

PERSON: "We come together as a community, each seeking the truth, and use our collective minds to strive towards it."

PERSON: "And that is why i critisize all things, so one day we might know something true."

PERSON: "No matter how difficult, if we argue rationally, with an attitude that the truth matters above all, it will be reached eventually."

PERSON: "Your species shows much promise..."

PERSON: "Species?"

PERSON: "Uh..."

PERSON: "Oh yeah, i forgot to mention, they decided to kill me, because everyone else actually hates all that stuff i just said."

PERSON: "Hmm on second thought...let's close off space travel to this whole area. This species is one of the dumbest i've seen. We'll check back in 2500 years or so."

PERSON: "What is happening now?"

PERSON: "Uh...what?"
