Re:Mystery of 60-Second Fluctuations in Power Grids Solved on Monday November 02, 2026 @01:07AM (#50333617)
i'm confused, why would a system simply checking its own power state be taking so much electricity as to show up on grid measurements? unless they mean that the systems are choosing to start charging the batteries, but then it's a continuous load and not a spike at the start of the minute, right?
Re:Diamond Transistor on Monday October 26, 2026 @05:10PM (#50251009)
try using a mouse or trackpad, they only seem to intercept pointer input. i also don't get affected when dragging the scrollbar or using the arrow keys.
Re:Diamond Transistor on Monday October 26, 2026 @04:03PM (#50250096)
i think they mean the sort of "inertial" scrolling that the site imposes

Re:Everything on Monday October 26, 2026 @12:14PM (#50246280)
there are other ways to share code than a monorepo, namely independently versioned packages. you say dependency hell but if you're in control of everything you're in the best position to avoid that if you put thought into it. with a monorepo you could actually get worse results in some cases. say i change something in a graphics api for sudoku and suddenly the zoom clone doesn't work. yuck. i only buy the monorepo argument for systems of code that actually need to be deployed in sync, like server/client stuff or larger. iirc google has a massive monorepo for nearly all of their production code because basically all of it works together (server/client stuff, auth, etc)

also a monorepo like this is worse for human interaction, if you care. what if someone only wants to pull and work on sudoku? now they have to get everything else. issues and pull requests are also more annoying to varying degrees depending on use.

Re:Everything on Monday October 26, 2026 @11:55AM (#50245914)
shoving all of these vastly different applications into one monorepo does not bode well for them being seriously designed, maintained, and cared-about pieces of software. such is the nature of LLM development, i suppose.

not to mention that there are only three contributors and #2 is claude, although that might be because they just committed a bunch of previously-untracked code at once, i don't care to check.

Re:The new iPad mini on Monday October 26, 2026 @11:50AM (#50245823)
notice, maybe, but care, definitely not. there's a reason TV manufacturers get away with leaving on that awful AI smoothing by default.
Re:SIMD-accelerated computer vision on a $2 microcontroller on Monday October 26, 2026 @11:48AM (#50245771)
nit: 5.1MP/s to 11.2MP/s is not an increase of 220%, it's an increase of 120%. it's 2.2x faster, but percentage increase starts at 0%, not 100%. 100% faster is double, 200% faster is triple.

Re:Apple HomeView on Tuesday October 13, 2026 @10:11AM (#50072072)
apple's usb-c port placement strikes again. the port for the wall-mounted one is apparently in the middle of the back, so you'll have to take it off the wall or risk damaging your usb-c cables by trying to keep them between the device and the wall. if it was just on the bottom (like an iphone or ipad) you could leave it hanging there while plugged in to a nearby outlet
Re:FlowCE: Calculus on your TI-84 Plus CE on Sunday October 11, 2026 @10:43PM (#50050697)
i don't see any changes in the fork of KhiCAS's giac that would suggest something like that.

https://github.com/tommyb3ll/ti-ce-giac https://github.com/tommyb3ll/ti-ce-giac/blob/main/kintg.cc#L...

why do you think it's unlikely? if KhiCAS does it, why wouldn't this fork?

Re:FlowCE: Calculus on your TI-84 Plus CE on Sunday October 11, 2026 @09:26PM (#50050180)
is this just a total guess? the repository says it's forked from KhiCAS, which is a ti84 port of Giac/Xcas, which can do full Risch integration if necessary

Re:Valen's Memory Safety: A New Kind of Borrow Checking on Sunday October 11, 2026 @10:13AM (#50043518)
nit: you need a better way of laying out asides/footnotes. when they get bunched up like at the start of this article you start having to scroll full screens back and forth. at least make the numbers on the asides link back to their position in the main text
Re:Show HN: gtlds.fyi – All the proposed new gTLDs on Wednesday October 07, 2026 @05:55PM (#49999318)
plenty are stupid or probably malicious but i'm happy for anything that will maybe convince people to stop making programs that check for a "valid" tld (they always have stale lists). i use an unusual ccTLD and i get told plenty that i've entered an invalid email
Re:Ask HN: Why is Ask HN only showing me 14 posts? on Wednesday October 07, 2026 @04:00PM (#49998050)
read the second sentence of my comment. if you'd like an example of a list that exists but is not on that page (in fact the one i mentioned not being able to remember), see https://news.ycombinator.com/genai-pushback
Re:Ask HN: Why is Ask HN only showing me 14 posts? on Tuesday October 06, 2026 @07:13PM (#49985510)
is there any place to find a full list of HN's lists? obviously there's the "lists" link at the bottom of the page but that is missing some, e.g. the above /ask (but /asknew is there?) and some others i've heard of but don't remember the link for e.g. a list of comments detected to be anti-ai

edit: just noticed /ask probably isn't there because it's in the navbar, lol. but still

Re:Type Safe Generic Data Structures in C on Monday October 05, 2026 @03:43PM (#49969607)
i guess i should say "the way that C++ _did_", although i do want to say "you know what i mean" since they do still share quite a bit
Re:Type Safe Generic Data Structures in C on Monday October 05, 2026 @10:43AM (#49965547)
zig doesn't "extend" C in the way that C++ does.
Re:Our AI Midwife on Saturday October 03, 2026 @05:02PM (#49947752)
this is one case. there's no proof here that AI will generally do better than human doctors. consider also that the power it has to convince people to push for better medical treatments can also be used to push for worse ones, or to halt standard treatment entirely, at which point it is much harder for the medical system to intervene as they aren't interacting with doctors.

Re:Don't couple your Go code to GitHub on Sunday September 27, 2026 @05:59PM (#49871281)
why not just use replacements to begin with if you don't want to bother with setting up domains?

"replace example => github.com/example/example" at first, then change to "replace example => gitlab.com/example/example" or similar when there's a migration

(i don't use go, but i hope this is possible and i am confused if it's not)

interesting, YouTube channel Veritasium just published a video on how Enigma was broken during WWII. at the very end they also give message that has yet to be decoded, although apparently they're different.

Re:Comparing reflection capabilities of C++, Zig and C3 on Saturday September 19, 2026 @10:59PM (#49772174)
"not an expert in zig" but you can't even look at the documentation to find the `@tagName` builtin to do exactly the problem posed?: https://ziglang.org/documentation/0.16.0/#tagName

i can literally google "zig enum to string" and the first result is a reddit post where the given solution is `@tagName`. i'm ready to write this post off as a low-effort ad for C3

Re:Steam Frame starts at $1059 on Monday September 14, 2026 @03:58PM (#49703044)
in my experience this is only an issue when headsets are unbalanced between the front and back, since this results in the weight going on your nose/face rather than straight through your head to your neck. the frame's battery is on the back specifically for this reason in addition to the whole thing being relatively light anyway
Re:DeCloudflare on Friday September 11, 2026 @07:37PM (#49666919)
from en.action.md:

> Redirect or block "Cloudflare Warp" users from accessing your website. And provide a reason if you can.

come on, really? what does this achieve? only thing i can think of is trying to get the user off of WARP, but i can pretty confidently say that before doing that i'll just not use the website. or if i really care about the content i'll turn it off until i'm done and back on it goes

Re:DeCloudflare on Friday September 11, 2026 @07:32PM (#49666869)
just sort of a general complaint about how much the internet relies on cloudflare and what that means. massive point of failure, erratic browser checks & outright blocking, surveillance
seemingly hugged, unless they're doing overzealous IP blocking
regardless of the validity of the claim, why post a link to Reddit when the Reddit post is just a link to a document? why not directly link to the document
