trentgreene··on Google fires engineer who called its AI sentient
‘So the meaning of sentience is subjective, so there can't be an objective definition acceptable to everyone and everything claiming to be sentient.‘

It feels like your begging the question here, I don’t think this follows from any of your arguments. Except for maybe where you state you believe sentience can’t be defined, which again, begs the question.

Though admittedly I don’t see much of a traditional argument — your conclusion is interesting, could you try supporting it?

trentgreene··on Thoughts on the potato diet
I also say, to whatever readers may care, the reason I belabor this point so much is that obesity related health issues have a massive effect on QOL, public health and personal mental health. I say this having grown up in the southern US, having obese family, having my own fitness / weight loss problems, having seen gangrene diabetic foots with my own eyes. I know vividly what it looks like for someone you love to be heavy, miserable specifically because theyre heavy, and totally hopeless that “they just can’t lose the weight”.

Throwing information out like this (w/o source and at best poorly replicated), that CICO is useless because of digestion rate, is incredibly dangerous because it falsely legitimizes that hopelessness. It traps people. And it maybe only applies in <1% of cases, where you have not just obesity but also compounding, very specific digestive issues. The opposite is also true — you don’t just drink coffee to knock off enough cal absorption to make a diff — you take laxatives you don’t need and have extremely abnormal, frequent BMs.

Anyone and everyone can lose the weight. It’s just CICO. You gotta figure out your input and output to account for the minor individual variances, and lock in a lifestyle to do it. But it’s just CICO at the end of the day.

trentgreene··on Thoughts on the potato diet
Not ignoring it - the in in calories in isn’t what you put in your mouth, it’s what you can absorb. Hence why you don’t count fiber towards your calories.

Again, the digestion point seems to reinforce CICO. If you gain weight because your digestion is slower (let’s grant the point), it’s not because your body some how treats calories differently, it’s that you’re getting more calories from your food. Your calories in are higher.

Not to mention that diet products have existed to game your digestive system to absorb less calories from your food. With the rationale being… less CI in CICO. See also: folks abusing laxatives for this purpose

trentgreene··on Thoughts on the potato diet
You got a source for that study? A cursory google didn’t reveal anything and 2-3x is suspect. To your second point, wouldn’t the microbiome (and slow digestion) just be another input into CICO?
trentgreene··on Thoughts on the potato diet
Au contraire, it's very useful. If you want someone to lose weight, calculate their BMR + their rough activity based cal burn, and give 'em a 15% deficit. They'll lose weight. Not just water and glycogen. They will burn fat.

If you want someone to gain weight, do the same calc, tell 'em to eat 100 more calories. Not gaining? 200. Really not gaining? Wow, fast metabolism, shock 'em with 500 extra. Anecdata, but the only time I saw someone not slowly gain on 200 extra, there ended up being a lot of walking we weren't accounting for in our maintenance cal calculation. Our O in CICO was off. For reference, 200 cals is like a 16 oz of coke, or 2-3 apples. Decently precise.

The variance between a fast and slow metabolizer isn't 20% of daily calorie burn, maybe 10% on the high end. Guesstimation, probably more like 5%. Well within the tolerances that are used for weight modulation (up or down).

If it weren't the case, why are so many body builders (natty or enhanced) able to run repeated bulking and cutting cycles? Are they genetic outliers?

Can you calculate it 100%? Nope -- so many variables, probably tons we don't even know about yet. But it's accurate enough to be very effective, and very simple to implement.

trentgreene··on Thoughts on the potato diet
It seems like everything in that article reinforces CICO. Is there something that diverges from the CICO model that I might be missing?

E.G. it’s examples of the Maasai and Inuit eating higher calories make a lot of sense when you consider their exposure to temp extremes and additional cal burn coming from thermoregulation (along with probably elevated levels of daily activity).

Most of the nuance I’ve seen around CICO that holds isn’t that CICO isn’t true, it’s that the intake and output are hard to calculate when you look at nutrient absorption and lifestyle

trentgreene··on The ‘E-Pimps’ of OnlyFans
I’m from neither FL or CA, but have lived (for 5 years+) in both S Florida, SV / SF, and a brief stint in LA. The cultures from all these places felt like two sides of the same coin. Compared to my native slice of fly over America, the flaunting and virtue signaling were pretty overwhelming

No, but I kind of miss it. My Facebook years were roughly 2008-2011, and they were magical. You’d talk with your friends in a fun, async, low stress manner, look at funny posts, hear about shitty but fun local shows, post literally random bs you were thinking. And people you know would really engage, Unironically and in good faith. I don’t remember a lot of clout farming in those days (MySpace had a decent amount, so I’m sure it existed).

I don’t think any other social media came close to how purely good Facebook was in its golden years. I’d love for someone to write a book on how it declined.

trentgreene··on Ask HN: Coworkers are suggesting I should slow down
At least to a 3rd party, it’s literally impossible to know why a colleague asks another to “slow down” without more context. I would however highly, highly recommend you 1) ask the colleague, softly, what they meant and 2) ask your manager about the situation.

For context, reasons I have asked colleagues to “slow down”:

- they were making many mistakes or suboptimal choices, sometimes really bad mistakes, and weren’t correcting when given feedback. Most of these cases, they seemed blissfully unaware of the work they were creating and the negative value they were adding.

- they were good engineers, but obviously burning out and miserable, which made it hard to give any criticism or suggest alternate approaches. See also “heroes”, the always-mega-swamped, and the perennially grumpy (these are different classes, but can be mixed). They also weren’t always aware of their effect on others.

- they were sidelining other peoples views and autonomy, demanding changes in other peoples components, making decisions outside their scope and domain of expertise, informally managing other folks work who were perfectly capable. This was usually done with a nice professional sheen — for example, “demanding changes” often takes the form of 1) writing full on features in another component, 2) making their own work kinda depend on that feature, 3) (finally) starting a very late convo with the maintainer of that component and putting them in a rough spot if the change was a bad idea from a broader perspective. Again, usually unaware.

It’s very easy to make the above mistakes — I have, most engineers probably have teetered, and I’ve seen it a bunch in my relatively short career.

I can say, I have never asked someone to slow down when they were hitting home runs, collaborating well, and making me look bad (please, I love to work with folks I can learn from, that’s engineering). It has always been a complex but totally salvageable performance problem I’m trying to guide back on track.

trentgreene··on How to Do a Handstand
I misspoke a bit — I specifically was referring to a neutral wrist position when pressing (be it bench, overhead, pushes) w/r/t extension. I’ve seen excessive wrist extension in these movements cause repetitive strain injuries, in my case they lessened significantly when switching to a neutral wrist angle.

I’d imagine flexion also ain’t great to press with, but excessive extension seems to be way more common (and in common push up technique, the norm)

As someone who majored in broscience with a minor in broceanography, this is def not broscience (henceforth “bs”). There’s none of the hallmark bs features like rigid adherence to a simplified / half true physiology or an assumed idea of what “fitness” is.

This is really something I think of as “fitness fluff”. It’s not really science, it’s a simple training plan that’ll probably work for >50% of the reasonably fit population. It’s also a training plan to accomplish a specific thing, do a handstand. It doesn’t really feel like a discussion on whether handstands are good and what regressions to apply where; why judge it so.

The bs and “real” science on nutrition and exercise both face a replicability crisis. The salt you take with all this bs (or studies, advice) will also help you achieve bigger pumps during hypertrophy training.

p.s. Don’t take the “bro” in bs too literally. It comes from all genders and identities equally. Anecdotally the biggest purveyor of bs in my life was a woman who went to med school. I still hear and say plenty of bs in my circle of crunchy climbers. You apply it moderately and trust your gut on what’s reasonable in the face of _massive_ complexity.

Same, and to any reader, make the switch to neutral grip on your presses _before_ you have wrist pain.
trentgreene··on Apple's director of machine learning resigns due to return to office work
I kind of fall into this category, but it's a little more nuanced. I have a very fulfilling social life / hobbies outside of work, and have taken sabbaticals before to great success. WFH was great because I could exercise a lot more, hangout with friends, etc.

But I am excited to be back in office on some hybrid schedule, because there was a social component to work that I very much missed. I enjoyed the work part of the work the same, but missed the occasional coffee with a coworker, full-fledged in person brainstorming session, off hand conversations about zany ideas, lunch at the cafe, etc.

It's not that my social fulfillment declined at all overall with WFH -- other social activities filled the time -- but the specific social activity of bonding in person with folks I worked with definitely decreased, and it's nice to have that come back. That's not a reason to force folks back in the office (this is at no-one's expense, as I've seen it suggested), but it's a nice benefit.

What is missing in your self reflection though is empathy for yourself, which will become more and more valuable in your career
trentgreene··on Ask HN: How to improve as a struggling junior software engineer?
If youre actually reflecting at this level after literally 8 months (months!!) of experience, and continue to march on, self reflect, stay motivated, don’t give up, you will eventually be a very good SWE.

Your team sounds awful though.

In addition to the high vs low level comments, I think another helpful connotation of the "engine" term is that you're often dealing with things that happen per frame, with many frames a second. The concept of an "engine" pumping out all these frames can be helpful.

This isn't to say that you don't write code which runs at framerate with a web framework, but often this is abstracted behind layout and user interaction concepts.

trentgreene··on Middle managers fear they've become irrelevant with work from home
Side note, I don’t know if some of you have actually been key players in a large org without management, but I have, and it SUCKS. If you think random slack pings are bad, try random slack pings plus 5+ hours of meetings a day you need to decline, justify declining, communicate about async, just to have time to get your work done. It’s my experience that without management, top performers are easily looking at 80+ hour work weeks

I notice this a lot with my European, African, and Latin American colleagues as well.

I’m not sure it’s a general trend, really gotta be weary of the “couple people in my life do x” -> “why do {general class} do x?” movement
