manzanarama··on Skills are quietly becoming the unit of agent knowledge
What do you think about checking the skills directly into the repo where they are useful?

manzanarama··on AI will shrink workforces within five years, say company execs
Consider the following example:

Two competing companies have 100 employees, and make 50 million per year. They each have 50 "computer people" each making 100k per year. Every day AI gets a little better and these people get more and more effective, if they are empowered, know how to, and choose to use it.

Their roles are slightly changing every day, as perhaps they don't take as much time on certain types of tasks, and the productivity seems to be slightly increasing. This boost may or may not result in increased sales or profit, but it is real.

Now let's say there is a breakthrough in AI, and it is clear that based on the exact actions that these people are doing right now, they can all be replaced with AI. And also let's say that one company chooses to do this, but the other company decides to keep all their workers and asks them to use the AI to do their current job and also push it to do what they always wished they could do but never had the time or could figure out how.

I can't see a world where the company that fires all their people and uses AI to do what they have been doing always comes out ahead.

Simply, for all jobs like this to be a real threat, it has to be the case that AI would have to be so good that a group og highly skilled and specialized humans working WITH an AI, would be no better than the AI by itself. And I think this is almost a paradox or impossible situation. How are its tasks defined, requirements met, priorities made?

So many of the successful companies are successful in spite of huge doubters to their strategies like Apple and Tesla. It is unlikely to me that an AI would spit out a controversial vision when asked to develop a new company, or a strategy within an existing company.

manzanarama··on Show HN: I made a cheap alternative to college-level math & physics tutoring
I don't understand what "because" is referring to...

"explanations.app has visual forums where university grads will properly resolve all your questions for $10/week, because the video explanations also benefit other students."

manzanarama··on Baltimore's Key Bridge struck by cargo ship, collapses
I have no idea what any of this means.
manzanarama··on ADHD Productivity Fundamentals
I feel like I am at odds with the scheduling one so much. If I time box all these little things, I get so distracted and I hate switching. I would rather go all in on something for a few days and ignore everything else, then circle back around and clean up the damage. I feel like this leverages the hyperfocus aspect of ADHD some might have.

Why? Won't this result in vastly inferior products?
manzanarama··on Cyclist hit by driverless Waymo car in San Francisco, police say
I feel like you are injecting facts with a lot of assumptions. How do we know a human driver would have taken longer? What if the human would have seen the bike 200 yards up the road 45 seconds ago, and since bikes don't disappear, waited a half second before proceeding into the intersection. Or what if a small portion of the bike was visible?

It could have been absolutely unavoidable but I don't think we know that now.

manzanarama··on Covid Test Data Breach: 1.3M Patient Records Exposed Online
I feel frequent data leaks, credit card number leaks, difficulty in un-subscribing or stopping payments after subscribing, etc... makes me appreciate and want to use consolidated sign in / subscription management / payment management options almost exclusively.
manzanarama··on Experiments on a $50 DIY air purifier you can make in 30s
I mean you can put regulations on anything to make it sure it is doing what it is supposed to be, right?

The spirit of the regulation is to make sure it is not emitting ozone like this ozone filter-less purifier: GreenTech GT-50.

It may be "painless" but if it costs $X per unit to certify and they make $x-.01 per unit, the company isn't going to sell that in CA.

The harm caused by the lack of a super cheap and effective air filter, especially in CA where we can get smoked out for weeks due to fires could be greater than the harm reduced by the regulation. Especially when it is obvious that this in now way could emit ozone since it is just a fan and a filter.

manzanarama··on We No Longer Need a Big Carrier's Wireless Plan. Discount Ones Are the Way
Researching this stuff and managing data usage like that is not worth the ROI for most people.
manzanarama··on We No Longer Need a Big Carrier's Wireless Plan. Discount Ones Are the Way
I know its a luxury but paying for a new phone every year on the best provider in my area is 100% worth it. I never worry about the battery dying, having good reception, etc... This cost maybe $100 dollars a month extra but its worth it to me.
manzanarama··on Why doctors in America earn so much
Really, what is a good ballpark for a family of 4? Is it like 5k a month?
manzanarama··on Why doctors in America earn so much
Maybe I am naïve but I don't get this age vibe really. I do backend java distributed system stuff for a large company. A lot of my peers and managers are "older" 40s and 50s with kids. A lot of the work is high collaborative and design focused. Maybe I am just in a bubble of an aging tech stack but it does seem like we are always using "new" (at least different) databases, caching, and network layers to stay somewhat current.

Its hard to imagine that 5,10,15 years of distributed systems and system design experience and knowledge along with domain knowledge and social skills will be all of a sudden be so irrelevant that it is worth phasing all of us "old guys" out for someone who happened to learn the newest programming language straight out of school.

We are constantly expected to learn the new stuff and will just a project assigned with a mandate "okay this is to be done in spring boot, using this DB, this HTTP layer, etc...

manzanarama··on The back-to-office backfire: Companies ending WFH perks lose out on top talent
This "losing out on top talent" thing is 75% true but I know a lot of career oriented people who are passionate about building the best product possible that prefer a decent amount of in office time to be able to better collaborate and get stuff done.
manzanarama··on The back-to-office backfire: Companies ending WFH perks lose out on top talent
I am torn, I 100% understand the huge burden of commuting and the amazing flexibilities of working from home. I have a medical condition where I essentially have to prepare or at least bring all of my own food. This is obviously much easier when I WFH, and can prepare food ad hoc.

Although I do work for a large famous tech company, I have a sweet setup where I can bike to work (to my desk) in less than 10 minutes in Bay Area weather (which is cooperative probably 340 days a year), we are not working from office 5 days a week, and its somewhat socially acceptable to work limited hours (lets say 10-4:30) in the office.

Working in the office, I am so so so much more aware of all the other projects my team is working on, and the org as a whole. I am able to pick up on so much more. The little conversations, both about work and not are lost when WFH. Obviously many companies never 100% committed to remote work, and some of this could be made up for by different technologies and processes. But in my opinion it will be very very very hard to reach the fidelity and bandwidth of information of in person work.

I think you have a long list of pros and cons here.

A while back I was thinking about what college may look like in 20 year. I was thinking of my experience in a California UC and how useless I found the lectures and but how incredibly helpful I found the office hours and studying with peers. I was thinking a distributed satellite model could be ideal. The lectures or base instruction could be remote, or even AI based, with small "campuses" or even just glorified rooms somewhere (library, strip mall) where small groups of students can meet in groups of 5,10,15 and learn together.

I wonder if something could be done for work as well. If larger corporations could maintain lots of tiny office spaces, near where people want to, or could live and require teams to be co-located. I truly think that if the commute was just a few minutes, and the hours in office were only required to be 6 hours or something, that the working in office would not be a huge burden.

manzanarama··on Could the world go PFAS-free? Proposal to ban ‘forever chemicals’ fuels debate
Are these forever chemicals an actual big deal? Do we have any numbers on how many people or animals they injure or kill every year? How about projections into the future? What kind of benefit do they allow manufacturers?
manzanarama··on The New York Times attacks e-bikes while ignoring the real danger all around us
Pedestrian bike path is a bit of an oxy moron. Bikes and e-bikes generally aren’t allowed on the sidewalk or where people are walking. I agree with that. A bike trail seems fair game. I could agree with a 20 or 25 mph speed limit for all types of bikes on a trail as well.
manzanarama··on US smartphone shipments fall sharply, but Android more than iPhone
I push back super hard on the "status" thing for Apple products. I don't understand what status it brings you and who gives you that status.
manzanarama··on Data brokers selling license plate location and analytics data
Can you register cars under a company or other shell entity? I feel like the only way to get around this kind of stuff is to have layers of abstraction above your identity.
manzanarama··on GM reverses plan to retire Chevrolet Bolt as it chases EV target
I never get the "discontinued model" thing. Isn't a last generation Camry just as discontinued when they start making the new one?
manzanarama··on Wind and solar will be 25% of U.S. generating capacity within three years
What resoruces are you talking about? Seems like everything can be solved with enough energy and the earth can surely produce enough energy through nuclear.
manzanarama··on The force that shapes everything around us: Parking
I agree there is this strange obsession with fixing super dense city areas, increasing density and public transit, getting rid of cars and parking, etc.. Im not sure why it is such a big cause right now. Its a bit confusing to see it so high on so many people's priority list.

I even bike to work every day since I choose to live very close to my office building, but I don't understand this desire.

manzanarama··on Underwater ears everywhere
This writing is so clear and good. I can't tell you how many NYT articles I read where the paragraphs feel out of order, chopped up and there is no consistent flow. This reads very enjoyably.
manzanarama··on Full Text of the Federalist Papers
There is probably that many people who have history degrees.
manzanarama··on Twitter's Dying. Time to Drop the News Paywalls
Bundles seem like a potential solution here.

Also I always imagined something like where I can load 20 dollars into an account and pay 10-20 cents for accessing an article. There could be a shared framework between many different news sites.

manzanarama··on New research puts age of universe at 26.7 – not 13.7 – billion years
I don't really buy this. That is like 819900000000000000 seconds.

Squaring this number gets you 672236010000000000000000000000000000 seconds.

I feel like my mind doesn't really appreciate either of these numbers or the difference between them. I feel like we just use units that we are comfortable with to make the number readable but there is not easy intuition here.
