It’s “where are you now?” month at Ask a Manager, and all December I’m running updates from people who had their letters here answered in the past.
There will be more posts than usual this week, so keep checking back throughout the day.
Remember the letter-writer who was miserable in their PhD program and just wanted to teach but didn’t think they could drop out? Here’s the update.
I regretted sending my letter in to Alison about three seconds after I hit the “submit” button. I was convinced that I was just whining, that there wasn’t anything that could fix this situation, and it was my job to just grit my teeth and get through it. Hearing from so many of you that you’ve been where I am, that you were miserable too, and that things were okay for you if you left, was just … thank you all so, so much.
I took on board all of your advice (and shout-out to those of you who mentioned education recruiter Carney Sandoe, I’d never heard of that!), and made a list for myself of things to try. I talked to other members of my committee, as well as my PI, about moving projects and labs as well. After quite a lot of deliberation, and a heavy conversation with my PI, I have decided – I might try to squeeze a tiny, inconsequential paper out of data I already have, and if so, I will get my Phd. Regardless, I will not be asked to do lab work anymore – and if I don’t get a paper, then I will master out.
My PI mentioned that, when I’d made the decision to leave, I immediately looked like 20 pounds had come off my shoulders. I feel like I’ve finally stepped out into the sunlight for the first time, after being shut in a dark room for ages on end. I keep waiting for someone to drag me back in, to tell me that no, you don’t get to have this kind of happiness, or that this has all somehow been a mistake. But it keeps not happening, and I keep feeling like breaking out into song and dance every time I realize that I’m still free from lab work!
And, now that I don’t have to do lab work anymore, I’m free to network my butt off! I’ve had informational interviews with adjuncts, private school teachers, public school teachers, program directors, and I’ve joined, like, three new professional networks now! I’m applying for jobs, I’m doing classroom observations to see what kind of teaching I like and don’t like, I’m gathering certification to help with my teaching skills – I’m doing the work! I’ve been fighting self-accusations of laziness for so long, as I found it so difficult to convince myself to do lab work, but it turns out, I can do things in a timely manner, I can put in effort, I just can’t do it around something that is actively hurting me!
Even better, because my PI is an amazing person, he’s allowing me to stay in his lab until this coming May (I’m getting paid for my teaching work, so he doesn’t need to use grant funding on me), and he’s supporting me in using as much time as possible for my teaching development! Also, for the course I’m TAing for now, I’ve told the professor that I’m interested in teaching, and that I’d like more responsibility in course design elements – and he’s letting me design the active learning activities for discussions now! I’ve also been playing around with making an intro biology course in my free time for a while (as in writing learning objectives, making slides, etc), and he’s offered to review my learning objectives and lesson plans for that too, if he has time, to give me feedback!
Speaking of which, someone asked me what I liked the most about teaching in the comments section – though I do absolutely love my students, and seeing them grow, I think my favorite part is the course design. I love creating a logical flow of information, I love when I make something as complicated as Bio clear and goal-based, I love seeing my students’ eyes light up when they realize that they know what they’re expected to learn, I love when the way I explain something just clicks, and finally a student understands why they’ve been asked to learn something, and how they can grow on their terms, get the skills they want, and that I’ve managed to help them on their journey. This, combined with some other elements from observations and interviews, tells me that K-12 teaching isn’t for me, as the curriculum is often dictated to you, instead of being in your control. But making goals, being organized, and clear communication are also very transferable skills – more evidence that there’s such a wider world out there for me than I realized!
Many in the comments also mentioned that mastering out is not failure, and I wanted to thank you all so, so much for that as well, because that is not the message I am getting from coworkers and friends. There’s very much a vibe of “we were all fighting the same war, now you’re abandoning us to go surrender to the enemy?!” and one of my work friends has decided to make it his mission to get me to stay no matter what (I don’t know why – we’re not in the same lab – I guess he just thinks I’m making a horrible mistake?). My family is also … not pleased, shall we say. Someone pointed out that I’m rather blind to the world outside academia, and that is more true than you know – nobody in my family has below a masters. No one. When I started reading Alison’s column, I was astonished that there were people who got jobs with just a bachelor’s, because everything I’d been taught said that the only point in getting a bachelor’s was to get a master’s, that anyone who stops at a bachelor’s is doomed to failure. Even though I am getting a master’s, it’s not viewed the same way – I know I have a few uncles who went to get a PhD, and when they mastered out, they stopped being invited to family events, which I don’t want to happen to me. My niblings are mostly matter-of-fact about it, but my parents are very visibly disappointed with my decision, and with the holidays coming up, there’s going to be a lot of dodge-the-conversation-topic with grandparents and cousins.
But I don’t care. If leaving this program can have this many people angry with me, and I’m still this light, and this happy, and this productive, then it’s more clear to me than ever that I’m doing the right thing. I have Internet strangers at my back, my bosses support me, I’m doing work I love, I’m supporting my students, my niblings have my back, and I’ve managed to respond to every comment and complaint from friends and family with confidence and enthusiasm. I don’t know what will happen next for me – maybe I’ll be unemployed for a year, maybe I’ll get a job at some company I’ve never heard of, or maybe I will be teaching as I wanted to be. But it’s my decision, and I get to decide to be free.

If you want a simple theme for a baby shower, it's hard to go wrong with cute little footprints.
Unless the baker misses the "little" part, of course:
Good grief, MY feet are smaller than that. Are you trying to give the mom-to-be a heart attack, bakers?
'Cuz if so, this is also an excellent way to go about it:
"Suddenly Nicola's plans for a natural, drug-free delivery seemed really, really stupid."
And how's the kid even fitting in there, Nicola? Do you have a TARDIS belly? o.0
Oh, wait, or maybe the kid is shaped like this:
On the plus side, he probably won't fall over much.
But we were talking about footprints, weren't we?
Which might be what these are supposed to be. Maybe. Allegedly.
Hey, ever wanted to see a duck with human feet that only walks backwards?
Well, tough. You're going to see one anyway:
Embrace the insanity.
And then waddle backwards with it.
"Sadly, little Mike's dream of becoming a professional dancer came with a slight disadvantage:"
And here I thought that was just a figure of speech.
Of course, the absolute creepiest thing you can do with a footprints shower theme is mistake "footprints" for actual feet:
Somewhere a quartet of elves is literally foot-loose and fancy-free*.
And probably pissed.
*If by "fancy" you mean "feet."
Thanks to today's arch-enemies [smirk] Layli S., Arlene P., Linda A., Gianna M., Anony M., Melissa B., & Becca H. for the sole-full feets.

And from my other blog, Epbot:
Dr. Mehmet Oz, the administrator for the Centers for Medicare and Medicaid Services (CMS) and former daytime talk show star, has recently been emailing all federal workers in his agency weekly tips on “Crushing Cubicle Cravings” and how to avoid snacking in the office.
“We all love a fun cookie swap and potluck this time of year. With several teams across CMS hosting holiday gatherings this month, I am sharing some strategies to help you make healthier choices—while still indulging in festive treats,” Oz wrote in his latest missive, which appears as a recurring section in his weekly bulletin titled “From the Administrator’s Desk,” according to emails viewed by WIRED.
“Set your intentions,” writes Oz. “Decide in advance how many treats you’ll allow yourself to enjoy and try to stick to that number. You don’t have to try every cookie on the cookie table.”
Nvidia, AMD, and Intel have all made high-quality image upscaling a cornerstone feature of their new GPUs this decade. Upscaling technologies like Nvidia’s Deep Learning Super Sampling (DLSS), AMD’s FidelityFX Super Resolution (FSR), and Intel’s Xe Super Sampling (XeSS) are all ways to transform a lower-resolution source image into a higher-resolution image, delivering better-looking games without requiring as much graphics hardware as you’d need to render the higher-resolution image natively. Later additions have focused on improving ray-tracing performance and “frame generation” technologies that boost frame rates by creating new AI-generated frames to insert between natively rendered frames.
Generally speaking, Nvidia’s DLSS technologies have provided better image quality than AMD’s FSR, but they have only been available on newer Nvidia hardware—the GeForce RTX 20-series or newer for most features, with frame-generation features locked to the RTX 40- and 50-series. FSR’s results don’t look as good, but they have benefited from running on just about anything, including older GPUs, Nvidia GPUs, and even integrated Intel and AMD GPUs.
Today, AMD is trying to shift that dynamic with something called “FSR Redstone,” a collection of ray-tracing and frame-generation features all intended to boost AMD’s image quality while being relatively easy to implement for game developers who are already using FSR 3.1 or FSR 4.

The post vote for the worst boss of 2025: round 2 appeared first on Ask a Manager.

A Virginia startup calling itself “Operation Bluebird” announced this week that it has filed a formal petition with the US Patent and Trademark Office, asking the federal agency to cancel X Corporation’s trademarks of the words “Twitter” and “tweet” since X has allegedly abandoned them.
“The TWITTER and TWEET brands have been eradicated from X Corp.’s products, services, and marketing, effectively abandoning the storied brand, with no intention to resume use of the mark,” the petition states. “The TWITTER bird was grounded.”
If successful, two leaders of the group tell Ars, Operation Bluebird would launch a social network under the name Twitter.new, possibly as early as late next year. (Twitter.new has created a working prototype and is already inviting users to reserve handles.)
It’s once again that special time of year when we give you a chance to do well by doing good. That’s right—it’s the 2025 edition of our annual Charity Drive!
Every year since 2007, we’ve encouraged readers to give to Penny Arcade’s Child’s Play charity, which provides toys and games to kids being treated in hospitals around the world. In recent years, we’ve added the Electronic Frontier Foundation to our charity push, aiding in their efforts to defend Internet freedom. This year, as always, we’re providing some extra incentive for those donations by offering donors a chance to win pieces of our big pile of vendor-provided swag. We can’t keep it, and we don’t want it clogging up our offices, so it’s now yours to win.
This year’s swag pile is full of high-value geek goodies. We have over a dozen prizes valued at nearly $5,000 total, including gaming hardware and collectibles, apparel, and more. In 2023, Ars readers raised nearly $40,000 for charity, contributing to a total haul of more than $542,000 since 2007. We want to raise even more this year, and we can do it if readers dig deep.
