This. I feel this all the time. I love 3Blue1Brown's videos and when I watch them I feel like I really get a concept. But I don't retain it as well as I do things I learned in school.

It's possible my brain is not as elastic now in my 40s. Or maybe there's no substitute for doing something yourself (practice problems) and that's the missing part.


We built an editor for creating posts on LinkedIn where - to avoid the "all AI output is similar/boring" issue - it operates more like a muse than a writer. i.e. it asks questions, pushes you to have deeper insights, connects the dots with what others are writing about etc.

Users appear to be happy but it's early. And while we do scrub the writing of typical AI writing patterns there's no denying that it all probably sounds somewhat similar, even as we apply a unique style guide for each user.

I think this may be ok if the piece is actually insightful. Fingers crossed.


A tangent, I wonder what kind of people actually stick around and read LinkedIn, the posts on there are so bad. I only go on there when I'm trying to get recruiters to find me for a new job. Instagram too I can't bear to use Instagram it has so many ads.


Yeah, much of LinkedIn is performative nonsense. However, with such a large B2B audience there, it offers a sizable opportunity for people who actually publish useful information and are honest rather than posing.

We have an "influencer" recommendation engine that is decent at finding such thoughtful folks, but it varies by industry. But yeah, it's not easy and I wish there were more thoughtful posters on LinkedIn.


So cool. Thanks for posting. I wish I was 1% the engineer this guy is.


A lot of the credit goes to Laura Waller, a professor at UC Berkeley who has been really innovative in this area and trains a bunch of really smart students. She has a great Optics Fun page, https://www.laurawaller.com/optics-fun/


Ah thank you! Sharing with my nephew who's there right now!


As a co-founder (tech background but haven't coded in a while), I got comfortable with sales best when I hired a sales coach. There are so many things to learn in sales and a coach is often the fastest way to assess your inherent weaknesses and address them head on.

I paid $2k/mth about 10 yrs ago; at the time I felt scared to spend so much but once I realized it was an investment in me, and I put in the time to learn, I can safely say it continues to pay off even now. I quite enjoy sales now. Not saying I'm good at it but certainly a far way from "I hate sales and would much rather code".


Do you think that sales is among the many realms where freely available quality instructional material has become ubiquitous in the past decade? Not that it would ever work as a full stand-in for a paid coach, but it might be enough to bridge the gap for some of us.


Yes I think possible. 1. sales aptitude assessment tools like Objective Management Group (the one I took) help you identify core weaknesses that are critical to understand and work on. 2. Recording your sales calls (assuming you're on the phone) and then asking AI to critique it and coach you, with the above assessment as context, could be very helpful.

If you're disciplined I think the above approach may be a pretty good stand-in for a real coach. Or at least help you evaluate a coach better should you choose to pony up for one later.


I'd be careful sending raw audio to public APIs given the sensitive commercial info. A local pipeline with Whisper and Llama 3 is viable now and solves the privacy issue. It also keeps the long-term inference costs much lower.


Llama 3 is far from cutting edge now and the value from quality analytics would far surpass risk adjusted odds of your info leaking.


Its like acting. Some people can do it without acting coaches. But it’s best if you invest in them.


How did you find a sales coach, how did you determine which was the one for you / any good at their job?


Mine was a referral from the VP of sales (the coach was his dad and many of the reps in our team had been coached by him). Fwiw, his name is Rick Roberge. I think he still coaches. He's can be a bit antagonistic but he's very good at what he does and I'm glad I hired him.


How many months did you do it for until you felt comfortable on your own?


My coach has a max timeline of 6 months so you are forced to swim on your own. I felt like I had the hang of it after about 4 months so stopped about then.

(sorry for delayed reply; I don't think HN notifies you of replies?)


Insane that Volvo doesn't just replace the car. The cost is trivial compared to the brand damage here. The complaint is so well documented and the customer is not being a jerk at all; not sure what Volvo's logic is.


Well if you don't replace the car you save 150K. But you lose a few million, let's say.

Those few million are invisible, the 150K you see right now and you know, for sure, you're saving it. Incidentally, this is how we got into this quality mess. Cutting quality seems like free money... except that it's not, it's just that nobody bothers to measure the opportunity cost.

And then one day you wake up and you're Chrysler, selling piece of shit vehicles for wayyy more than they're worth. And now your brand is worthless. But, at least you saved a few bucks ;P


They would need to replace all faulty cars after that. They want to avoid that.


They'll probably agree on a settlement where they don't admit any wrongdoing and give him a decent payout, but require him to take down the site and sign an NDA or something. So they don't necessarily need to replace all of them after that

If all he wants is a refund, that should do it. But if he's more interested in warning the world, hopefully he sticks to his guns and makes them give a straight up refund


> A new car built by my company leaves somewhere traveling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don't do one.

- Fight Club


I'm guessing that's every car.


Exactly…


Ah you might be right. But:

1. If they really have so many faulty cars on the road that's a serious hazard and any accidents where people die may end up destroying Volvo entirely because of negligence.

2. An economically reasonable answer might be refund the guy making the complaint and ofter all other owners $10k credit towards your next Volvo purchase or free 3 years of maintenance and service. Something like this might be enough to stem the bleeding while protecting the brand.


Agreed. Put another way: because software has low marginal cost and high up-front cost (even higher in very competitive markets) it makes sense to raise venture early to hire a great team and build an awesome product that then scales incredibly well (great investment returns).


Oh cool! Thanks so much. (Btw, I didn't mean to suggest that the project should address an unanswered question. Ok to repeat known experiment if it's fun/insightful).

The gravitational acceleration one is cool. I remember doing this in high school back in the 90s. Let me suggest that to him. Thanks again.


Xpertly | Founding fullstack engineer | Remote (US), ideally Bay Area | $150k + 1% equity

Sorry for tangent but any recommendations for small smart phone (i.e. <6" screen)?

I like my iPhone 12 mini with its 5" screen (though it is glitchier than one would hope) but now all phones seem to be 6"+ which is hard to fit into a pocket or even manipulate with one hand.

I know the Samsung ZFlip 6 and Motorola Razr+ are small, though rather pricey at $800-1000. Any opinions from folks on reliability/usability etc of these?

I am embarrassed to say I have some Apple lock-in with earbuds and even basic conveniences like "find-my" working for my children's watches so not sure if these are worth staying with Apple for, even if I dislike their latest devices.


I'm very curious if experienced staff is available and less expensive now. As a venture-backed startup founder myself I'm quite eager to hire such folks and don't have the money to compete with larger firms. Maybe silly question but where are such folks hanging out, besides HN? :-)
