gertlex··on Imagine 130M Washing Machines
That seems very lucky of the second city. Let's hope we get lucky with some generous billionaires soon!

I don't claim that regulations are simple, and incentives couldn't be created to result in infrastructure investment by the wealthy... but I won't hold my breath.

gertlex··on Waymo halts service during S.F. blackout after causing traffic jams
I'd default to assuming it's the respective roadmaps for Waymo and Tesla differed on which things to implement when, not training data, that results in the two behaving different.
gertlex··on I'm Kenyan. I don't write like ChatGPT, ChatGPT writes like me
I wonder if you've heard the expression "hitting your stride".

(native english speaker who was a bookworm as a kid; I admittedly had to ask gemini to recall the general phrase that I had in mind)

gertlex··on Australia begins enforcing world-first teen social media ban
Am I wrong in feeling like the solution you outline is only applicable to an individual's kids? But at the societal level, it clearly seems we can't depend on enough parents to do what you talk about. Something else is needed.

I don't have answers to give. Certainly not a fan of the government approach of "everyone must prove their age online now", which I believe is how the AU law is done. (casual listening to Security Now podcast about this for a long while now)

gertlex··on Ask HN: Should "I asked $AI, and it said" replies be forbidden in HN guidelines?
I haven't had a reason to use Google Translate in years, so will ask: Have they opted to not use/roll out modern LLM translation capabilities in the Google Translate product?
gertlex··on Microsoft has a problem: lack of demand for its AI products
Nah, they probably just have Copilot as a bullet point on a slide, count that as "using AI", and are psyched for their next board meeting.
gertlex··on DRAM prices are spiking, but I don't trust the industry's why
apparently wspm is Wafer Starts Per Month

guess I'm interpretting "1million wspm; add 10%; was effectively a 20-30% capacity increase" in 2015.

Not sure where 5% then comes from. Guessing "relative shrink" is referring to process size (5, 4, 2 nm, whatever) not linearly corresponding to density of transistors, etc.

gertlex··on Ask HN: Hearing aid wearers, what's hot?
Tell us more; what's driving this model as your choice? Or is it more of a "prefer getting similar to what I currently have, and this is the model that makes sense"?
gertlex··on Ask HN: Hearing aid wearers, what's hot?
That's certifiably not fun :(

Not that one ever should have to do such for medical equipment, but wonder if someone could grind down the firmer stuff on the first new mold, assuming it was kept...

(Not really useful anecdote:) I remember circa 25 years ago, my audiologist had a benchtop grinding/buffing wheel that she'd take the earmolds to a few times when modifications were needed. Even at that young age, it was clear that grinding soft materials didn't work very well.

gertlex··on Ask HN: Hearing aid wearers, what's hot?
I haven't used telecoil since I had analog HAs, probably. I learned about the even lesser-known DAI (direct audio input) option before I got my first pair of digital HAs. Since then, I've used cables, and almost as long (15+ years now) have had modified pairs of bluetooth headphones:

https://hackaday.io/project/1406-bluetooth-headphones-for-he...

Sadly, it seems modern Phonaks (and probably everyone else) no longer makes DAI "boots" for their BTEs.

I'll probably be ok with the transition, but it's going to annoying having to recharge hearing aids during the day. Right now, I can get 6+ hours of music/podcast/meetings/phone calls on my (5+ year old) headphones batteries, and can take those off and charge them when not using them. (and other perks...)

I'll have to refresh myself on telecoil to see if it's of use. (My BTEs still have it, iirc)

gertlex··on Ask HN: Hearing aid wearers, what's hot?
I wear BTEs and got new earmolds made by phonak this past summer, but I'm in the US. I'd classify them as firm silicone, and doesn't seem 3d printed. Seems like the same material as the previous molds (which I wore for almost 8 years).
gertlex··on Ask HN: Hearing aid wearers, what's hot?
I'm in a similar age range (HAs since 1991 I guess). I also have fond recollections of the pre-digital HAs' sound.

I'm using a pair of 8 yr old phonak BTEs, which have various levels of directionality focusing. (Actually, I'm down one HA; 8yr old on left; 13 yr old left one one on right ear... getting new ones in January) I too prefer a lower level of directionality as my default.

I assume your HAs are doing bluetooth for the music setup you describe? Or are you describing a setup with speakers at home?

gertlex··on GitHub: Git operation failures
My pushing was failing for reasons I hadn't seen before. I then tried my sanity check of `ssh git@github.com` (I think I'm supposed to throw a -t flag there, but never care to), and that worked.

But yes ssh pushing was down, was my first clue.

My work laptop had just been rebooted (it froze...) and the CPU was pegged by security software doing a scan (insert :clown: emoji), so I just wandered over to HN and learned of the outage at that point :)

gertlex··on Steam Controller
My usecase for the steam controler was limited (robots); I've always used the dongle, and never needed/desired to explore direct bluetooth as an alternative.
gertlex··on Steam Controller
Indeed it does, I now see. Interesting!
gertlex··on Steam Controller
A niche usecase: it switches to a bluetooth connection instead of a usb dongle.
gertlex··on Sustainable memristors from shiitake mycelium for high-frequency bioelectronics
Planet/mindworms in Alpha Centauri :D
gertlex··on Falling panel prices lead to global solar boom, except for the US
I assume that the extra regular (daily?) cycling of the battery in your car would have a notable effect on your vehicle battery's longevity. (But I'm very fuzzy on how battery improvements in the past ~decade have applied to "cycle life", or really even what the cycle life means, e.g. is end of life when it's something like 70% of total original capacity?)
gertlex··on Building a Robot Dog (with an airsoft gun)
Having had a chance to read more of the blog now, maybe the most pleasing part is your similar discovery of, "I'm writing my own kinematics, and generating plots of it is the fastest validation of that code". I did similar matplotlib plots of my quad (spider) leg movements years ago. Definitely need to do more of that when I finally revisit the software on my mech from 2019 with AI help :).

And more generally, yeah, having the AI manage some of those plotting needs will be fantastic in other work too; I enjoy figuring out what to plot, and don't mind wrangling and hand-refactoring said scripts... but it's so time consuming historically, and there's always the itch to urgency to get back to the "main code". (at least I learned to gradually convince peers that often plot scripts should be commitable without being polished; they're a form of documentation sometimes!)

gertlex··on Building a Robot Dog (with an airsoft gun)
I can't quote it offhand, but it's stuff like:

- Don't stick your camera on an arm and poke it around corners to see the opponent

- No detachable parts? It's more nuanced than this. Not leaving "mines" I think is a case of this.

Basically there's a few goals to the rules (this has been an on and off competition for about 15 years now): keep the spirit of "pilots in giant mech robots" (loosely 90s era stuff), and homogenize the competition slightly for competitiveness.

Melee is still allowed! If you walk into the other robot and trigger one of their 4 score panels, that still counts.

It's a hard competition to prep for. Numerous bespoke HW subsystems, software, budgets that grow quickly with the size/weight of your bot... and being reliable.

OP getting this robot working in about 3 months was insanely impressive.

gertlex··on Poison, Poison Everywhere
Feels like you're on a different tack here: improving your "own life" is different from solving "collective problems".

Further, setting up solar + batteries solves a non-modest individual problem, but is not by itself (i.e. reducing carbon footprint; an example mentioned in the parent's link) the solution to climate change. (yes it helps; but incentives leading to people installing solar have a much bigger impact; and the biggest incentive was maybe China building a solar panel industry, but I'm not trying to go down that tangent)

gertlex··on Louis Rossman: Politician calls constituents criminals with no right to privacy [video]
I'd assume they'd just do like European politicians do (so I hear), and advocate solely for privacy for politicians, not others. (advocate, as in write bills excluding themselves from being monitored)
gertlex··on Space Elevator
I wonder how standard this globe size is. My mental one is the one we had at home that was about 15" in diameter I'd guess.

Another comment talks about atmosphere being a 1 mm layer on a grapefruit... so definition of atmosphere extents might be different in these two anecdotes.

(edit: I submitted this comment two minutes after another comment did the math on the globe/paper layer version...)

gertlex··on How AI hears accents: An audible visualization of accent clusters
Hard of hearing, from the midwest; also identified as Swedish by the accent guesser.
gertlex··on Don't Be a Sucker (1943) [video]
I didn't watch this yet but am going to be curious to hear how to not be divided about "we now have masked agents roaming the streets kidnapping people in broad daylight. In the United States.", when some clearly think there are reasons this isn't a problem (or not worth paying attention to).
gertlex··on Figure 03, our 3rd generation humanoid robot
A bit on the nose, and entirely serious:

I moved to CA a decade ago to join a robotics company.

I've since acquired a wife, house and dog. Wife loves to cook, and would love a 2nd dog that didn't choose me. I am a sucker for DIY. If I were in an apartment still, with no pets... i.e. lots less chores to do (hooray hybrid work!)... I'd be seriously considering roles at Figure, which is 100% in-office instead. (their office is a sub 10 minute walk from my last apartment)

How long that work satisfaction would last... very up for debate though!

gertlex··on Python's splitlines does more than just newlines
splitlines() is sometimes nice for adhoc parsing (of well behaved stuff...) because it throws out whitespace-only lines from the resulting list of strings.

#1 use-case of that for me is probably just avoiding the cases where there's a trailing newline character in the output of a command I ran by subprocess.

gertlex··on Figure 03, our 3rd generation humanoid robot
My initial reaction to the hotel scene was: Ehhh, I like being able to read lips, as I wear hearing aids.

But yeah, I'd happily just check in at a kiosk and get my room card that way. (And I'm sure phone-as-key, no-contact check-in is only going to get more common)

gertlex··on X-ray scans reveal the hidden risks of cheap batteries
Thanks for the reply! I was not thinking/claiming individual cells had a BMS on them, but was referring to the "pack" level protections.

Your mentioning of specific failure modes helps me, specifically breaking up the failures into multiple categories.
