PetitPrince··on Kona EV Hacking
Installing a non-standard button that hijack the light control of the car to light all of the rear one is not hacking ? https://techno-fandom.org/~hobbit/cars/ev/yb.html

I appreciate the autopilot effort of comma, but if this isn't hacking in the most classic sense of the word I don't know what is.

PetitPrince··on A useless infinite scroll experiment
You should add a punchline about training for a thumb war (with a rocky reference ?).
PetitPrince··on I Powered a Car using 500 Disposable Vapes [video]
Previously this youtuber repurposed used disposable vapes batteries to build a powerbank, then a e-bike battery, then a powerwall. This is the latest in this escalation series where he powers a small electric car. Note that he did take security into consideration, with fuses everywhere, thermal sensor and a proper BMS. The latter also enabled him to charge the whole assembly via USB-C, which I find hilarious.

PetitPrince··on Exposure Simulator
Ah ! Guilty as charged in not reading the whole page.

> Now, I'm just not sure how would one simulate a running fan with a picture.

I don't think it's necessary for this app. This is simulating what the camera sees, not what our eyes can see.

PetitPrince··on Exposure Simulator
For me it's missing something to illustrate the relationship between shutter speed and motion blur. If the subject was a running fan instead of of lightbulb that would have been ideal.

I see where you're coming from, because my robot tends to eat the cats toy as well as my computer charger cable. In my case the prep is minimal, as it's just putting them on the sofa. Otherwise the robot has no problem charging and returning home, (I only had issue 3 times in 5 years ?). Concerning the bin I have pets so in my mind I have to empty the bin after each run. But psychologically I see tons of hair so in a way it's satisfying to see a job well done. The pets are fortunately well behaved so poop smearing is a non-issue (some more recent robot also have object detection to avoid this kind of stuff).

In any case, the ritual is to run it every odd day or so just before leaving for work so the mental burden is low.

PetitPrince··on Why is the sky blue?
> I feel like sticky nav and sidenotes aren't particularly unusual?

Not unusual, but you used them with taste and restraint, like the rest of your layout and animations. That's something that HN comments like, I think. Notice the distinct lack of "OMG some fancy presentation trick ! Litteraly unviewable!" comments that often happens when an unusual layout is presented (and often with reason; but sometime to a fault).

I guess the main praise your page UI is that it looks, well, like a page. But augmented I guess ?

Personnally I really like the way you used a grid to separate the content from the nav. I like that you used both the left sidebar for nav and for the header number (re-using the same space for multiple purpose feels elegant, because those purpose are secondary to the content, if that makes sense). And I like that the grid anchors your eyes by fencing the different chapters along with the nav. (and now that I mention it, it feels weird that the headings are outside their chapters, but it didn't felt like that upon first reading).

I agree with the general vibe of your post but let me make a tangeant:

> I always think of my Roomba in this kind of situation, namely when one tries to imagine a future where tech works outside of the computer. Basically my little vacuum robot mostly sits idling in the corner because... a basic broom or a normal vacuum cleaner is radically more efficient, even if it means I have to do so myself.

For me the whole value of a robot vacuum is that... I don't vacuum, the robot does, and when it does so it when I'm not at home. Reduce the dust periodically by 75% so that it's neater; I'll do a deep clean every few month or so.

(maybe what you're saying is that the cost of vacuuming for you is low enough that it's similar to launching the robot vacuum, in that case I understand you !)

PetitPrince··on PlayStation 2 Recompilation Project Is Absolutely Incredible
Yeah I was responding to the opinion that old games are good because of nostalgia, which I don't agree with at all. Some are good because of nostalgia, some are good because they're just that good (there's a thriving community around NES Tetris for instance), some are good because they pushed the medium forward (Metal Gear Solid, Warcraft, The Sims, ...).
PetitPrince··on PlayStation 2 Recompilation Project Is Absolutely Incredible
I join my voice in disgreeing with this. While some games can indeed be rose-tinted (I have fond memory of that Game Boy Spiderman game, and it's a terrible shoverware game), many of them are traiblazer (like, invented a genre) or are still standing on their own very well.
PetitPrince··on France passes bill to ban social media use by under-15s
> the social media of today don't seem all that much different from the internet forums of back in the day

The message boards I participated when I was a young teenager were mostly focused on a specific topic (a specific videogame or series of videogame, or a specific genre), with some off-topics board on the side. They were contained communities; village-like if you will. If you don't like one you could hop on another website that had another set of members, customs, and rules.

(yes, you can sort-of see that small village feel with some Discord group or subreddit; but back then the media were controlled by an admin, not a centralized for-profit group)

Contrast this with today's infinite feed were everyone could potentially reach anyone, all curated by The Algorithm(tm) with a vague notion of "friend" or "subscriber".

PetitPrince··on Show HN: isometric.nyc – giant isometric pixel art map of NYC
More like Sim City 3000 methinks. Sim City is more pixel artsy / lower resolution, while 3000 have enough resolution to feel more like an illustration rather than a videogame.
PetitPrince··on CD Projekt issue DMCA takedown notice against popular Cyberpunk VR mod
"he has the same mod" is downplaying it. He's adding VR for games with widely different engines. Same functionality yes, but vastly different codebase.
PetitPrince··on The longest Greek word

PetitPrince··on San Remo Pasta Measurer
Clever !

I was thinking of something like a sugar dispenseur (turn the container to fill a volume, and this volume becomes you serving), but your solution is way more economical and space efficient.

PetitPrince··on Agonist-Antagonist Myoneural Interface
Man, is this still sexy science !

In a parrallel universe, I am still be working in that domain (I was in Silvestro Micera's lab (he did similar kind of feedback for the hand) for my Master's thesis - also a long time ago; it didn't go so well due to an expectation mismatch from both myself and my supervisor)(I now work as a software engineer... pay and oppotunities are better).

If I understand correctly (I only skimmed your paper), the method you used is to take a muscle, cut it in two lengthwise, use those as a pair of muscle to graft, then put two nerves close to it and pray for re-inervation. Then you use EMG as a basis for your signals.

- Help my brush up my EMG knowledge: what's the tradeoff in choosing the muscle ? For a human case such as the one provided in the link, do you have the same signal quality choosing a smaller or bigger muscle ?

- I assume you're using intramuscular EMG (you're doing surgery anyway, so you might as well put some electrodes). How does this behave over time ? I had some experience in brain-computer interface, and I know scar tissues and the like is a real issue that can come up over time.

PetitPrince··on Intricuit: A touchscreen add-on for Mac laptops
My significant other uses her touchscreen laptop as a consumption device (for video and prose; a lot of fanfictions!) in the bed (a beefy tablet with a built-in stand resting on her belly, if you will). In that context she's very happy with a touchscreen and is a factor when buying a new laptop (fortunately that Thinkpad X1 Yoga from 2017 is still going strong).
PetitPrince··on Htmx: High Power Tools for HTML
> HTMX would work well with jQuery.

Note that HTMX is supposed to be Intercooler 2.0, which is itself using jQuery https://intercoolerjs.org/ .

PetitPrince··on GOG Patrons- Join gamers keeping classics alive
> Like take the Resident Evil example FTA: Launched in 1996, 2000-2023 not available (i.e. not for legal sale).

The Resident Evil IP is still alive and kicking though (with the latest installment trailered during the game awards a few weeks ago).

PetitPrince··on Roomba maker goes bankrupt, Chinese owner emerges
My D7 lost its mapping capability (including markerless no go zone) a few weeks ago due to the new owner pulling the plug early on their server. An enthusiast is jerry rigging an offline solution thanks to a vuln in an earlier firmware, but for those unwilling to solder an esp32 to the debug port of their vacuum they essential got a lesser robot overnight.
PetitPrince··on Why we can’t quit Excel
I think the best we have at the moment debugger view; in other words a snapshot of the state of the system. Maybe with a dashboard you can see some progression over time ?

(I somehow though of the videogame Factorio and of that thing called Labview, but I cannot form a coherent thought about it)

PetitPrince··on Multivox: Volumetric Display
> imagine a spinning display like those of the article but somehow tuned so that they are only visible when exactly head on

I don't understand: doesn't defeat the purpose of a volumetric display (seeing what is displayed from multiple point of view) ?

PetitPrince··on Games using anti-cheats and their compatibility with GNU/Linux or Wine/Proton
An elaborated version of this idea is called "rollback" where you let the local client predict and execute the game state at time t+1 and will "roll back" the state of the game if it received another game state than the one predicted. Extremely popular and state of the art for 2D fighting games (most of the time the prediction is correct and it greatly reduce the perceived lag) , but probably harder a bit harder to do with 3D games.
PetitPrince··on Engineers repurpose a mosquito proboscis to create a 3D printing nozzle
From the paper:

> The ink used for the proof of extrusion demonstration is a ready-to-use, polyethylene oxide–based training bioink purchased and used directly from the vendor (Cellink Start, Cellink)

> The ink used for the honeycomb demonstration and the maple leaf demonstration is a sacrificial, temperature-sensitive, 40% (w/v) Pluronic F-127 in deionized water bioink purchased and used directly from the vendor (Pluronic F-127, Allevi).

> The ink used for the first cell-laden grid demonstration is Pluronic F-127 bioink with B16 cancer cells suspended in solution.

> The ink used for the second cell-laden grid demonstration is Pluronic F-127 bioink embedded with RBCs.

> The ink used for the cell viability experiments is Pluronic F-127 bioink with B16 cancer cells suspended in solution.

PetitPrince··on Steam Machine
Fortunately while Squarenix is still important to Playtstation (and Tetsuya Nomura to Squarenix), it's not the juggernaut it once was in the early 2000.

(for those who don't get it: Tetsuya Nomura is a director at Squarenix and known (amongst other) for its Kingdom Heart series who ends up with word salad title such as "Kingdom Hearts HD 2.8 Final Chapter Prologue" or "Kingdom Hearts 358/2 Days")

The Swiss Weather Office official app has a crowdsourced photo gallery:

https://www.meteosuisse.admin.ch/services-et-publications/ap...

Look at the pictures from 3AM onwards on the 12 of November: you'll have a nice overview of how the aurora looked like from Switzerland (it's a time sensitive app and they certainly don't keep the pictures forever).

PetitPrince··on Laptops with Stickers
I think the only stickers I saw on cars in France and Switzerland are the "baby one board" and "<stick figures of the members of a family>".
PetitPrince··on Sued by Nintendo
> nd it's near-impossible to make a falling-tetromino puzzle game without making it look and behave like Tetris.

What's more is that you cannot release a Tetris game if you follow the exact gameplay specification the Tetris Company mandates. And those specification prevent a whole range of gameplay, leading to stagnating game design and the impossibility to play some higher difficulty style of Tetris.

It's as if the First Person Company LLC mandated a Halo style floating jump with regenerating shield. There would be no classic Quake and the Doom revival series (2016, 2020, 2025) wouldn't be able to center its gameplay on agression (or at least, it would feel very weird).

PetitPrince··on Rockstar employee shares account of the company's union-busting efforts
HL3 kinda happened though, but it was called Half-Life Alyx. And while it wasn't a conventional FPS like HL1 and 2, there's absolutely no trace of GaaS in it.
