And which of those lets you access you bank, or use Government ID?
jnovacho··on Dear people who work at the airport
The flight number is on the ticket/boarding pass.
jnovacho··on Recycle – Floppydisks
What band is that? Also how do they do that? Just heavily compressed mp3?
jnovacho··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
The enshitification I mean, applies to the new models. Once the current device dies, you need to replace it.

And in the future, the offline devices might be no longer available, because they stopped being produced. And only new shittier ones are for sale.

jnovacho··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
Firewall blocking is not the point. The point is, that over time through enshitiffication the new device will require call home to unlock. Even when it does not need internet to work at all. But through this the vendor will get a foothold.

Sure you can block it, but then you have a pricey paperweight.

This is not unique to Thread/Matter, they can pull the rug on ZigBee as well, ofc.

jnovacho··on Self-Powered Trailers Promise Leaner Freight Runs
This trailer saves 7000l of diesel per year. Assuming 40l/100km, with this trailer you can go ~17.000 km more, which is 11-17% more, for the same fuel cost. Or ~12-15k EUR in fuel savings per year (assuming 1.8EUR/l).

With 13+ years ROI (electricity is not free) is this really beneficial?

jnovacho··on Should you normalize RGB values by 255 or 256?
> index 0 holds values from 0-1, index 2 from 1-2 etc,

Well, now you are double counting the end values of the ranges. In your example 1 is included in both 0-1 and 1-2.

jnovacho··on Two days of oatmeal reduce cholesterol level
Doesn't soy mimic estrogene, thus causing potentially other issues?
jnovacho··on TikTok users can't upload anti-ICE videos. The company blames tech issues
Sure, but are they running audio recognition and image recognition models on each upload just to classify it?
jnovacho··on TikTok users can't upload anti-ICE videos. The company blames tech issues
How is TikTok able to screen this en masse? Are they going after tags? Political issues aside, I am really interested in the technical background in this.
jnovacho··on Show HN: Shellock, a real-time CLI flag explainer for fish shell
There is https://explainshell.com/ not in terminal but should do the trick.
jnovacho··on Uncrossy
In tutorial, it did not accept HIM as a solution, because it wanted DIM. Kinda confusing.
jnovacho··on Vietnam bans unskippable ads
Firefox on Android has UBlock Origin available. But that covers the browser only. I guess AdGuard and VPN might help here?
jnovacho··on A startup’s quest to store electricity in the ocean
Oh, right thanks for clarification. They are indeed not pumping just any salt water, but much heavier brine (which they get who knows where).

So if there is any leak in the system, it will kill local wildlife right, like the brine pools under ice in Antarctica.

jnovacho··on A startup’s quest to store electricity in the ocean
How exactly are they pushing the brine against the ~50BAR pressure differential?
jnovacho··on Ventoy: Create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI Files
How does this differ from Rufus [0] or Balena Etcher [1]? [0] https://rufus.ie/en/ [1] https://etcher.balena.io/
jnovacho··on Don’t Look Up: Sensitive internal links in the clear on GEO satellites [pdf]
They mean the intersection between the cone produced by the satellite and "illuminated" surface. If the antenna beam is normal to the sphere, it will produce a disk which has an diameter.
jnovacho··on I ditched Docker for Podman
> Privileged ports in rootless mode not working? Good! That's security working as intended. A reverse proxy setup is a better architecture anyway.

So, how are you supposed to run the proxy inside the container? Traefik for example? Genuinely curious.

jnovacho··on AR Fluid Simulation Demo
Virtually any LCD screen will produce polarized light. This is the core working principle of those screens. So if you use a polarized filter (sunglasses for example) it will completly block the image coming from the screen.

You can see the effect here: https://www.reddit.com/r/mildlyinteresting/comments/crvpil/t...

I believe this will not work with OLED screens though, but I do not have one to test this.

This was the central theme of https://www.youtube.com/watch?v=IjJmTeBSEzU
jnovacho··on Show HN: I made a tool to generate photomosaics with your pictures
How exactly does this work? The example I chose is a mosaic of photos, over which is overlayed the original image with alpha set to 50%.

So it does not use the submitted photos as tiles, right?

jnovacho··on I hacked my washing machine
I believe that US 240V is 2 hots, neutral, and ground. EU 240V is one hot, one neutral and ground. EU 400V (380V) is 3 hots, neutral and ground.

None of this is cross-compatible.

jnovacho··on Wind Knitting Factory
To recycle plastic, the only viable way is to melt it. And the plastic must be very clean before it can be remelted. If it even is a kind of plastic that can be reheated multiple times. I am afraid the short answer is no.
jnovacho··on Japanese scientists develop artificial blood compatible with all blood types
Donated blood has a limited shelf life. So this is about the stocks the donation centers have. This tech can use the almost expired stocks to "recycle" the donations, instead of destroying it.
jnovacho··on CVE program faces swift end after DHS fails to renew contract
It looks like the decision has been reverted, for now at least: https://www.forbes.com/sites/kateoflahertyuk/2025/04/16/cve-...
jnovacho··on What sank the Bayesian superyacht in Italy?
From skimming the article, it seems the boat sunk in about 2 minutes. While most of that time it was already laying on it's side.

This would make it virtually impossible to get out, if you were below deck.

jnovacho··on We're excited about our new roundabout
Yep, in my city we have a roundabout with 4 cardinal directions, roughly aligned with compass directions.

The West connection is to/from highway, so it has most traffic. People arriving from North/East/South want to leave on the West. And this causes massive jams, as the constant supply of traffic going from South entry to the West exit (i.e. doing left turn, and passing all ramps) essentially blocks all the other traffic.

Roundabout are great, they increase safety of dangerous intersections. But sometimes a controlled intersection is just a better idea.

jnovacho··on How to win at CORS
Do you have any recomendations, which proxy to use? Specifically on Win.
jnovacho··on Spearmint – JavaScript Test-Code Generator – New In-App Testing
Hi, this thing interesting. But the main site is kinda lacking details. If I'm not mistaken, the images cannot be zoomed in, so you cannot actually see what's going on. Plus the site is missing any how to, quickstart, tutorial, basically any info on how to use the thing.
