jti107··on How Claude's text watermarking works
anthropic speed running its way into irrelevance. wtf would i use AI for writing that screams AI generated especially when I'm not in the EU and open models are so good now
jti107··on A Silly Adaptation of "The Odyssey"
watched it on IMAX and I thought it was great. personally I love movies and I've been a big fan of Christopher Nolan and the only movie I didn't like from him was Tenet.

also lots of reviews online about it being woke, if this is you then skip it...this is art from an artist and if you don't like his vision then skip the movie. no one is forcing you to watch it

jti107··on I was wrong about the Midjourney ultra-sound scanner
one thing it can be used for is ultra precise body fat estimation and localization. depending on your genetics you might be skinny fat but have alot of internal visceral fat that is very damaging to your health.

the state of the art is dexa scans but they can be off by 5+% and more error on the distribution of the fat

jti107··on Mythos is shaping up to be a nothingburger
"We also haven't seen any bugs that couldn't have been found by an elite human researcher."

bro this is like the first gen, in two years they will iterate and get better. this is just like first gen video, text and image generation were crap but people saw the potential. i've been involved in natural language processing and TTS and in the span of 1-2 years we have seen some crazy innovation. now you can run really great expressive open source multi-lingual TTS on phones and edge hw like raspberry pi's. they have completely wrecked career prospects of voice actors and translators.

if i was a bad guy, i could spin up a 100 agents and find exploits faster than the number of elite security researchers on the planet could fix it. imagine getting the latest version of apple ios and have a new vulnerability within a few days to a week

jti107··on Ask HN: How do you fight YouTube addiction and procrastination? I'm struggling
I know what you are going through and what helped me is taking extreme measures.

You have to first do a dopamine detox...you mention YouTube but it's usually a lot more than that. You probably addicted to a lot of other stuff (like porn, food, sugar, TikTok). You need to give your brain a break from the over stimulation.

what does this look like? get rid of all your electronics except what is essential. for me this is just my phone, kindle and laptop. as soon as I get home my phone goes in an electronic time lock box and its locked until next morning. on my laptop everything is blocked like YouTube and only the stuff essential is available (I'm on my Mac I use an app called SelfControl). get rid of your junk food and eat wholesome home made meals. replace YouTube with other interests you have always wanted to do preferably something that doesn't require electronics like drawing or reading or playing an instrument

After 30-60 days you feel a lot better and more at peace with yourself. at this point you have a decision to make, can I go back to where and keep it under control or do I need to make this the rest of my life. for me I chose an analog life and I avoid electronics as much as possible. I use instagram and YouTube but I have iOS timers on them so it's blocked after my allowed time runs out.

jti107··on AI won't replace human devs anytime soon
our company uses them LLM's extensively for coding and it was something that was optional the company paid for. we got training on how to use it and was told don't blame the LLM for shitty code, you're responsible for the work you push to the branch. most people ended up using it...our superstar dev uses it and he think he is way more productive with it.
jti107··on Ask HN: Is anyone working at least 4 hours daily on an Apple Vision Pro?
I bought one bc I travel a lot and it's been a game changer for me. Both in terms of watching movies and also getting some work done.

Having the something similar to a multi monitor setup in a portable setup is amazing.

the negatives are the battery and the weight after couple hours. I can do a max of two 2-3 hour sessions per day and anything more would be pretty rough. Ideally I just do one 3 hour session and the rest on MacBook.

is it cool...yep! is it a necessity? nope. would I recommend it? nope. do I love it and use it a lot? yep

I can't wait to see what Apple does with this after 2-3 generations. i still think VR is looking for that killer app.

jti107··on Berkshire halves Apple stake, boosts cash to $277B as it gets 'defensive'
its been pretty much the same iphone for last 5 years...the only new innovation have been satellite texting messages, 120 hz screens and improved camera/cpu. yet Apple has continued to do well...i think your example of S curve and market saturation is fine but Apple has an entire ecosystem and is catering to luxury and high end market so the same rules dont apply (see LVMH as an example in luxury goods). they sell phones, tablets, computers, high end audio, watches, services and all these things just work well together. no other company on the planet comes close...other than maybe google.
jti107··on The Marshmallow Test does not reliably predict adult functioning
anedotally this has held up in my social group. the people that i grew up with and went to school with...the ones that could delay instant gratification and had long term goals ended up doing pretty well in life. the ones that didnt have any plans and just went with the flow did poorly and just getting by.

also in my life i notice a big difference in performance from when i had goals/vision for my life vs. going through the motions.

IMO i think you need to have goals/vision/standards for all the important areas in your life (hobbies,partner,career,family,relationships)

jti107··on First anode-free sodium solid-state battery
pretty cool...but when it comes to batteries what matters is scale and total cost. it doesnt matter if the elements are cheaper, are you introducing a product that is significantly better or cheaper that the current status quo (see the rise of LFP)?

can you use existing factories and manufacturing techniques or do you need to invent or build those. we've started hearing about solid state batteries about 15 years ago and we still dont have any at a big enough scale. if solid state batteries do takeoff it will probably takeoff first in electric aviation and supercars which can hide the cost due to a more expensive products and the need for higher density

jti107··on 120ms to 30ms: Python to Rust
use the right tool for the right job. your software requirements and design document should drive the language and the tools you use.
jti107··on Private Equity Is Now Dominating the US Hospice System
damn...something to look forward to i guess
jti107··on The Military-Industrial Stock Buyback Complex
Sparta is the closest example i think of. all the men were soldiers and all the hard labor/farming were done by slaves/healots. eventually led to technological stagnation & societal collapse
jti107··on Mass layoffs and absentee bosses create a morale crisis at Meta
fantastic! everyone left is hardcore
jti107··on Ask HN: What are some of the best university courses available online for free?
can second this...also recommend his books
jti107··on EV startups from Lucid to Rivian see demand fade, supply chain issues linger
sell something like the ID4 for $30-35K and you will have tons of buyers. will be interesting to see how many ID4's they sell because they cost $40K and they are made in Tennessee so they qualify for the EV tax credit which puts them in that price range.
jti107··on Godot 4.0 Stable
this is awesome...i've started dabbling in game dev and was messing around with unreal 5. i will have to give this a shot
jti107··on 3D Model of New York Available for Free (and Commercial Use)
this is really cool work. do you guys have any white papers that describe your technical approach?
jti107··on Ask HN: How do you deal with information and internet addiction?
Yep totally agree, you will need need to solve the root issue at some point. The detox is just to meant to give you a chance to look at the situation clearly and hopefully put you in the path to addressing the root issue. which hopefully means you won’t need to medicate thru ur addiction
jti107··on Ask HN: How do you deal with information and internet addiction?
i'd suggest reading Dopamine Nation, essentially the premise of the book is modern society has hijacked our natural reward system and we havent figured out how to moderate ourselves. author suggests 30 day dopamine detox so whatever you think you're addicted to (social media, sugar, sex, news, drugs, alcohol, etc.) force yourself to not use it for a couple of weeks and see how you feel. you should go thru intense withdrawal but in the latter weeks you're body and mind should be reaching a new equilibrium. she also mentions usinng challenging things (cold showers, exercise, etc) to reset your hormonal reward systems
jti107··on Tesla’s Cybertruck Delayed Again
it will be interesting to see how many of these turn into actual orders. i'm a big fan of cyberpunk but it was jarring to see it in real life. i get similar vibes to brutalist architecture
jti107··on Yann LeCun: ChatGPT is 'not particularly innovative'
well he is right that the techniques used have been around. but this is the first mainstream AI that most people outside of the AI community have been impressed with and found useful to do real world stuff
jti107··on In the past, I've had students call my problem sets “emotionally trying”
seems like they are looking in multiple bands hence the 4 spatial dimensions

"Our approach differs from previous work by combining 3D and spectral super-resolution simultaneously with readily available fluorochromes as well as operating in a wavelength range where biological autofluorescence is minimised."

jti107··on Ask HN: Why has eInk technology stalled compared to other display tech?
what do u mean by stalled? they released color eink and are planning to release next gen color panels, faster refresh rate panels and foldable displays. if you’re willing to pay for it you can get 25-40 in eink monitors. considering the small market for eink I think they are innovating
jti107··on How France Changed the Tides of the American Revolution (2018)
fascinating read…I never realized the French were so involved. without their help it seems we’d have lost to the British
jti107··on Skilled tech workers snapped up despite downturn
try usajobs for federal. for CA there is calcareers, should be something similar for the state you’re interested in
jti107··on Skilled tech workers snapped up despite downturn
if you're willing to relocate and not picky there are tons of state/federal programming jobs. couple co-workers got picked up by NASA for Javascript/C++ programming
jti107··on Amazon thought Alexa would be the next iPhone. But it's a glorified clock radio
not sure about alexa but google assistant/nest audio is pretty great and i'm finding it quite difficult to stop using it.

i use it for everything from playing music, adding stuff to my to do list, getting sports scores, turning on/off my smart lights, to figuring out measurements and setting timers while cooking.

the speech recognition and speech synthesis is great! this is actually the only google product i still use...everything else has been replaced by apple, duckduckgo, fastmail, etc.

jti107··on Spotify CEO renews attack on Apple after Musk's salvo
if i build a store and allow companies to sell to my customers...i get to dictate the price. if you don't like it then innovate and build your own store or develop a direct relationship with the customer. spotify should team up with elon to build a competitor to apple just like epic decided to compete against steam. this is how free market capitalism works...if they decide apple is doing something monopolistic then the federal courts give spotify an avenue to pursue that. build your case and sue apple
