icodestuff··on Show HN: Graft – Claude Code hooks that cut grep tokens by 42%
The graph is pre-filling the context that does the sync, right? Doesn't that create a bias towards what's already present? If anything hallucinated does make it in at some point, won't the sync just reinforce that hallucination if some new component touches the bad info, just like a long session rabbit-holing? New sessions, in contrast, have no contextual assumptions and often catch those problems.
icodestuff··on Show HN: Graft – Claude Code hooks that cut grep tokens by 42%
Love the idea, I was thinking about this problem a few weeks ago, but never got anywhere with it. I'm intrigued by the latency savings in particular, that sounds great.

One concern I have is that right now each session gets fresh "eyes" on the problem. Right now I find I get a lot of mileage out of a combination of long-running sessions and fresh ones. I worry with a single generated concept graph that gets only incremental refreshes will become stale slowly, and in subtle ways that are hard to detect. That could lead to semantic drift in the graph from reality, and every new session will take the drifted form as gospel. Have you run any long tests (weeks or longer) on this to make sure that this doesn't happen? My understanding is SWE Bench is only a point-in-time evaluation.

Also the graph is stored in the repo, right? How mergeable is it? I know I wouldn't want to do conflict resolution on that myself, and even Opus struggles to keep all the references correct (especially when comments are involved) when there's an B->C, A->B symbol rename.

icodestuff··on Should DayQuil Be Legal?
I only know one person who has ever found phenylephrine effective. It's definitely not for me, but they've done single-blinded self-studies (with help) to see if it's a placebo effect, and it's pretty clearly not.

DXM is also not a placebo, although it might be specifically for cough.

I don't especially want the FDA to ban them, but requiring separating out the acetaminophen might not be the worst idea.

icodestuff··on Gravity has always been quantum mechanical: it is the wrong thing to quantise
I'm not much of a physicist, but this rates a 9.5/10 on my personal BS mater. A single citation, two lines of analytical mathematics, a promise to resolve the Hubble tension without actually doing so quantitatively (or indeed, even conceptually), and I'm pretty certain (> 99%) that the no-hair theorem applies specifically to black holes, not other massive objects.

I know a little bit more about orbital mechanics, and I know that the internal structure of a planet matters for the stability of an orbit. While at larger distances the effect becomes small enough to ignore, it never really goes away. Whereas a black hole is indeed thought to behave like a point mass.

icodestuff··on Advanced Mac Substitute is an API-level reimplementation of 1980s-era Mac OS
Eh, there were plenty of games that were coded for a particular clock speed, and then once the SE came out, had an update that included a software version of a turbo button, let you select which of two speeds to run at. They run FAST on an SE/30 or Mac II and unusably fast on anything newer.
icodestuff··on Efficient Computer's Electron E1 CPU – 100x more efficient than Arm?
Yep, that’s definitely the question. The article says that there are caches of recently used graphs for use in large loops. Presumably those are pretty fast to swap, but I have to imagine programming a whole new graph in isn’t fast. But maybe the E2 or E3 will have the ability to reprogram partial graphs with good AOT dataflow analysis.
icodestuff··on Show HN: Skip – Build native iOS and Android apps from a single Swift codebase
For sure. Pretty similar problem space, very different implementation and target market. Apportable wasn’t a transpiler (and boy were we proud of that); it was a reimplementation of the iOS frameworks on top of a replacement NDK (Android’s libc was bad-mediocre at the time. Real nasty behaviors in its (dl)malloc for instance). Similar to WINE. It was always targeting games, so there was never a lot of effort to port any of the UIKit controls, but OpenGL CoreGraphics were supported. It also had a compiler extension that let you access the whole Android SDK in ObjC, and a tool for generating ObjC APIs from JARs. The goal was to make ObjC the one true mobile dev language. I applaud the effort to do something similar for Swift, even if it does involve transpilation.
icodestuff··on Emulsifiers linked to increased diabetes risk
While the large sample size and many controlled variables are good, and make the results statistically significant, the effect sizes are awfully small. Only two of the emulsifiers, tripotassium phosphate and guar gum, increased the hazard of an individual developing diabetes by more than 10% (11% and 15% respectively, with very large error bars in the latter case). These are much smaller effects than previously known Type 2 diabetes risk factors.

For instance, the HR for family history of diabetes is 4.46 (vs 1.03-1.15 here, where 1.0 is no change in hazard).

icodestuff··on Emulsifiers linked to increased diabetes risk
No. None of the ones with an increased Hazard Ratio are or contain them.

The researchers also did not control for PUFA consumption, only SFA consumption.

icodestuff··on Inside the Super Nintendo cartridges
> Even Super Mario World[10] got the treatment (I can't remember slowdowns but I was only twelve can then).

Yoshi’s Island 4 has a slowdown in some circumstances (have Yoshi, get Starman and hit P-Switch), as does another level I can’t recall, exactly… it has a bunch of Monty Moles that explode all at once. I think it’s on Chocolate Island. I think there might be a third with two Sumo Bros. and an Amazing Flying Hammer Bro. onscreen.

This again? Last time this came up, it was calculated that in order to get to the levels (mg/kg body weight) found to affect fertility in study rats and pigs, you’d have to eat something like between 2/3 and 2x your body weight/day, every day (because it’s easily excreted), of chlormequat-contaminated oats. The studies on rats and pigs used much higher concentrations than are found in oats.
icodestuff··on Built-in workaround for applications hiding under the MacBook Pro notch
The notch is what it is: a compromise between webcam quality, branding, and thin bezels. But it’s hard to argue but that Apple’s software integration with it is mediocre at best. None of the extra space is usable except by anything but the awkwardly tall menu bar and the status items or menu extras it holds, and the system not being aware of the notch —sometimes— like letting status items pile up underneath, or being able to put the mouse pointer underneath it but not when a mouse button is held down (this behavior was removed in a late version of Ventura), or putting the picture-in-picture window partially underneath the menu bar (like it expects only a regular-sized menu bar to be there)… is symptomatic of a larger quality and integration problem at Apple, I think.
icodestuff··on Ask HN: What 1980s/90s-era shareware did you purchase?
EV: Nova was the first shareware game I ever paid for. Also how I learned to use ResEdit. The Ship Variants mod was the best! There was nothing quite so overpowered as a Type IV Modified Valkyrie, a ship that was basically impossible to capture in stock without a massively larger ship or small fleet. It had most of the cargo capacity of a stock (Type I) Mod. Valkyrie, but about 3-4x the weapons mass, filled with missile launches and an ion beam (unheard of on a 2-day jump ship), and with room to spare for a medium laser.
icodestuff··on Japan's Hometown Tax (2018)
More, even, since ridings don’t all have to have the same population, unlike Congressional districts.
icodestuff··on A Threat to the U.S. Budget Has Receded, and No One Is Sure Why
They don’t mention falling life expectancies. If people are dying before they use as much care as expected, small wonder costs would rise less.
icodestuff··on Ask HN: How to Focus Again?
Are you burnt out? I watched that happen. They also have ADHD, but once they burned out, even interesting worthwhile things couldn’t hold their focus for more than a few minutes, and they were constantly procrastinating several levels deep. That lasted months.
icodestuff··on Flying Toasters Screensaver After Dark in CSS
SETI@Home was fun, but it was kind of a trash screen saver because of how many fixed elements it had. Definitely ended up burning in a monitor with the yellow afterimage of its purple section divider bars.
icodestuff··on Show HN: PC Builder AI
Not sure where you’re getting pricing data, but it’s clearly out of date. A Ryzen 5 3600 is $97 on Newegg ($92 after rebate), not $350. Tools like this absolutely must have up-to-date pricing to be useful.
icodestuff··on Is NGC 1277 a problem for MOND?
I think something like the bullet cluster, where you have gravitational lensing consistent with a collision-less fluid, leading a baryonic colliding gas (which we know is present from X-ray emissions), was a prediction of CDM. So it hasn’t predicted nothing, but yeah, I want to see more.
icodestuff··on LK-99
Huh. The second paper listed different vacuum pressures than the first. 10^-3 torr instead of 10^—5.
icodestuff··on The first room-temperature ambient-pressure superconductor?
My first thought was “I really hope this is real and not someone having left the data collection software in simulation mode.” If this reproduces, it’s historic. If it doesn’t, it’s either cold fusion or faster-than-light neutrinos.
icodestuff··on Douglas Adams was right about telephone sanitizers
I seem to remember the end of the telephone sanitizers story was that you shouldn't get rid of them no matter how annoying, lest a plague spread via telephone handsets.
icodestuff··on Mozilla restricts extensions on some domains on Firefox 115
Ad blockers and password managers are primarily what I’m installing, and they interact with all sites.
icodestuff··on Mozilla restricts extensions on some domains on Firefox 115
Looks like there will be a UI to control this 116, and the block list is empty in 115.

I’m pretty stoked for this. Every time I install an extension I wonder what’s going to happen to my banking info if an update ever gets hijacked. This is a much better solution than turning all my extensions off and on when I visit financial websites.

icodestuff··on An app can transform smartphones into thermometers that accurately detect fevers
The pulse is probably doable but difficult, at least on an iPhone. The noise in the accelerometer data from just holding it is pretty substantial.
icodestuff··on Some subreddits are now filled with NSFW content to protest Reddit
How long until Reddit changes their (self-imposed) rules around advertising in NSFW subs? I’ll guess about July 2.
icodestuff··on Full Interview: Reddit CEO Steve Huffman Isn’t Backing Down
I think Reddit gave away the game plan when they decided to remove API access to NSFW subreddits. Between that and making the mobile app required to view them (blocking mobile web), they’ve basically created a porn app, not just a glorified web browser, and managed to get it into the App Store. One with no private browsing mode, no ad blockers, and resetting all of your advertising identifiers is high friction (you have to create a new account). This is an adult content advertiser’s dream come true. Of course reddit wants complete control over it.

That’s why the blackout protests are doomed. Unless it causes enough people to stop using reddit altogether, they will have no effect.

icodestuff··on The Supreme Court Made Just About Everyone Happy for Once
Roe v. Wade was 7-2, not 9-0.
icodestuff··on The damage to lunar orbiting spacecraft caused by the ejecta of lunar landers
That doesn't bode super well for Blue Origin's lander then, since its engines are on the bottom.
icodestuff··on Running a movie theater is more expensive than you can possibly imagine
If you're in San Francisco or New York, maybe. If you're in the rust belt, that's going to be a much higher proportion of your costs.
