It sounds like VPN by Google is an effective strategy for keeping users from using ad and tracking blockers, then; for contrast, iOS routes the connection to the private traffic server over your user VPN connection if one is active.
altairprime··on Tuesday Morning Topline: Waymos Not Allowed Near Waterfront for Fleet Week
Direct article link to their reporting source: https://www.kron4.com/features/fleet-week/san-francisco-rest...

Original source is SFMTA’s page detailing Fleet Week impacts on transportation services: https://www.sfmta.com/travel-updates/fleet-week-october-9-11...

The title of the map shown is “Fleet Week Autonomous Vehicle Restrictions” which also seems a better title for this post, though perhaps with SF prefixed at the front to explain why this is (more) newsworthy than other fleet weeks anywhere.

altairprime··on Tamagotchi Hacking, in Depth
This feels like a summary-rehash of a prior HN post — and certainly I support a repost of the topic but the article felt rather clunky (and also after reviewing https://apexcreativesmedia.com/yorker-media/), so here are some original works to support the topic.

Many Tamagotchis were harmed in the making of this presentation (2012) [video] (3 years ago, 26 comments) https://news.ycombinator.com/item?id=38458651

That discussion links to both her slides and her blog detailing all of her work over time in rather considerable detail, for those interested:

altairprime··on Strong evidence that 'baryon junctions' give proton its identity
Editor's summary of the original paper is relatively coherent for outsiders, since this link obscures the DOI hyperlink in unclickable paywall:

> Baryons, particles containing three quarks, carry a baryon number of 1. The total baryon number has been conserved since shortly after the Big Bang. However, it is still unknown what it is inside the baryons, either the quarks or the gluons that bind them, that carries the baryon number. The STAR Collaboration presents evidence from three types of collisions that can help to distinguish between the two scenarios (see the Perspective by Li). The data disfavor the hypothesis that quarks are the carriers of the baryon number.

— "Tracking the baryon number with nuclear collisions" https://doi.org/10.1126/science.ads5962

That 'Perspective', slightly earlier in the issue, has this abstract; it is either more, or less, instructive than the above depending on one's familiarity with the topic:

> The proton sits at the heart of every atom. It was once pictured as a cluster of three quarks—constituents of matter whose properties combine to produce the proton’s characteristics. Increasingly precise experiments have repeatedly challenged this classical view by revealing that a proton is not merely the sum of quarks, but a many-body system whose defining properties (such as mass and spin) arise from the collective dynamics of quarks and the gluons that bind them together (1, 2). Yet, the origin of the proton’s baryon number—a conserved quantity that distinguishes matter from antimatter—has remained elusive. On page 727 of this issue, the STAR Collaboration (3) reports experimental measurements that could resolve a decades-old debate over how baryon number is carried and transported. The findings offer insights into the origin of the proton’s identity and how matter is organized throughout the Universe.

altairprime··on System-level ad-blocking in Android
> an apparent undisclosed ad for Nord

What evidence supports the link referenced being an advertisement? I'm not seeing any referral, tracking, or any URI parameter data at all that would support the claim, and this seems to be their only instance of referring to it — where, in this 'state of the union' helpdesk-style article, one or more such 'VPN provider' links seems particularly relevant to visitors. (I do not use whatever this company's products are and have no opinion either way on them aside from mistrusting the claim presented here.)

altairprime··on Account bans on Reddit
> I wanted to share my open-source solution on Reddit. I created an account

This is the core error of understanding, and that same error leads to a great deal of bad Show HN’s as well:

Platforms want repeat business. Or, in classical retail cafe terms: Platforms want regulars.

Signing up for Reddit solely to self-promote something is indistinguishable from how one defines ‘spam’: unwanted promotional links delivered from reputation-free accounts. HN chooses to tolerate the Show HN flood to some degree because it’s classically of interest and open by design, but also comes with a dramatically more expensive human moderation burden that Reddit has decided they would rather not pay.

That I can summarize this post as “Self-promotion by unreputable or disingenuous participants is usually a bannable offense in online communities”, without having to even name whether it’s Reddit or HN or MeFi or RPG.net, suggests that this is much more a ‘fuck around and find out’ learning moment for the author than something of material interest to HN. Certainly there’s no surprise at the outcome: a competent anti-spam automation that triggered the first ban would have banned the domain regardless of which account is involved, to prevent swarm bot attacks that are well-known for some years now to webforum operators.

If amoral, they could have been emboldened by exposure to AI use, either their own or by other students, colleagues, etc., while lacking inherent moral pressures for/against slop.

If moral, they could have decided that propagating their message will improve the world, even if only at x% efficiency due to use of AI, and that their intentions will take precedence over being accused of slopping.

If immoral, they could have chosen to run a grift on the chance that no one would notice, overdone it, and then played every card in their hand while perhaps sweeping away evidence of their slop once caught.

altairprime··on Reverse Engineering the iPod Classic's Undocumented Mikey Chip
Post author, excellent work on this; for future long press investigation:

> So the center button is now click-only: every debounced rise emits a fixed 60ms click pulse, and there are no hold semantics at all, because the chip can’t reliably report press duration.

This reliability point seems incorrect. The chip reports a valid press duration when less than 5 seconds have passed since the last plug-in or button press events; and, the chip reports an invalid press duration for presses of less than ~1.8 seconds when 5 seconds or more have elapsed since prior events. That is perfectly reliable behavior, and I expect the 5 second threshold is hard-coded into the OEM Mikey drivers to account for it. It’s perhaps unpalatable to consider coding support for that, and certainly I don’t fault the choice made here; but that’s not cause to label the design “unreliable”.

Looking at the long-press controls for wired earpods, this seems to have been accounted for by the software design: during playback, either you double- or triple-tap the button followed by a long press; or, during call scenarios, you long press in response to an incoming call event, or you long press while in a call. These are all compatible with the 5s sleep compromise; ‘pick up call’ and ‘hang up call’ can be reasonably allowed to take 1.9 seconds to be registered as a true long press, if they haven’t already forced the chip awake for responsiveness. Perhaps of more interest to Rockbox, however: during-playback long presses are always preceded by multi-taps, which I assume results in some interesting signal patterns that I don’t see explored by this writeup.

altairprime··on Snap Wants to be a State Actor??–Kansas v. Snap
Failing to turn over proof to a judge would not particularly protect them, so that will hinge on them filing a (presumably sealed) exhibit in response to a judicial request compelling them to submit it. Seems a very poor bet to take since the judge is likely to reject any simple ‘data sharing’ or ‘crypto weakening’ order as not compelling the totality or even a majority of their business, which is ‘sharing public and private gossip between friends’ — a goal not materially hindered by compulsory wiretapping, any more than it would have been for Ma Bell or her successors. However, if the government’s order is dictating their actions to the degree that they have no freedom of action regarding this case in specific, then it could work. That seems a particularly unlikely scenario; it’s much more likely that they’re just witlessly pulling a judicial lever that an AI proposed to them, than that they are a true puppet of FedGov. We’ll see.

altairprime··on We're gonna need a lot more mathematicians
> I have in mind something like a “deployable intellectual reserve”: communities of mathematically sophisticated people that humanity can call upon to help understand consequential AI-enabled breakthroughs.

I can’t afford to be one of your credentialed reserves, Amit. ADHD screwed me over in early life or I’d have breezed through that dual masters in cognets/compsci by 2003, and now that I’ve stabilized my brain and am burning through years of school at a rapid pace, my country’s socioeconomically ruined — I’ll be lucky to escape with my accounting degree as my school is visibly being sucked into the vortex every year I progress. The only hope left for me to be what you need of us is to self-study, but without a degree I’ll just be treated as a crank or an AI proxy/puppet if I slip up and talk about interesting math with anyone, so what’s even the point of taking that path? I originally pivoted my math skills into systems theory and process diagnostics instead, which of course now everyone has kicked to the curb and replaced with AI. I’d have made an excellent Susan Calvin — I was working to be a cognitive tech with diagnostics, zeroth law, and group psych specialties, AMA! — but the financial investment to provide the runway to take that lonely, dreary six year slow as molasses slog through maths that universities think is somehow an appropriate teaching velocity (six months for precalculus alone?!) in order to earn the mere chance to have my resume rejected by an AI firm that uses AI hiring and and can’t tolerate someone with a strong moral position regarding societal harms is a very bad choice, whether you use simple probability or game or systems theory to evaluate it. Taking that quarter-mil-plus burden as loans in the hopes of employment at the other end in a field actively having its social, reputational, and moral fabric being ripped apart by AI? That’s not just a bad bet, that’s chasing fool’s gold at the end of a fading rainbow in a desert mirage. So, with sincere apologies, while you’d benefit from having me on your ‘reserves’ list (I have written testimonials spanning some twenty-plus years to that effect) I’ll never come to your attention as a support tech or as an accountant, and I accepted that outcome years before anyone else realized this need for cogsci mathematicians with a teacher’s specialty of analogy-building and the ability to disregard interpersonal nonsense to focus on the needs of societies. Better luck with the next generation, though!

Yeah, that tends to be the case, but an attempt to persuade that goes nowhere counts more towards bans for such behaviors than insult and dismissal — so long as they're not a VC, anyways. The alternative is the Bystander Effect and that seems somehow worse.

altairprime··on DoorDash Spent $1.4M Trying to Stop Mamdani from Becoming Mayor. Now We Know Why
My issue is with rhetorical methods such as that, yes, but let’s not cross the line into mocking the people using those methods. Rhetoric is often taught in morally-neutral terms in the schools underpinning tech — especially at Stanford, the big one next door to YC/HN in Palo Alto! — and the seeming insult of that comparison (I’ve never seen Columbo) will make people less likely to reconsider their rhetorical choices. Whether they want to be heard more successfully or (as I hope) they realize that rhetorical methods are morally-charged in real-world communities or they’re asocial like me and this offers a method-hack for social interaction efficiency, it’s the method that matters here, not the person behind it.

(One benefit of being nameblind at HN’s community size is that it’s easy for me to treat everyone the same, because I lack any recognition for whether I’ve spoken with someone previously or not. I acknowledge it’s not that easy for other people, but certainly it has the upside of forcing this ‘method, not person’ approach I describe into every interaction I have here :)

altairprime··on Cortical thinning and hippocampal expansion linked to ADHD symptom trajectories
In the supplementals, note tables S15-S18 where the researchers find an absence of correlation between medications and remittance; suggesting that, for the sample analyzed, medication treats the symptoms but is not a cure. This tracks — I don’t know of any ADHD med that has a permanent improvement effect! — but it’s useful to see that reflected through an analysis of brain scan data.
