Maybe they meant encoding, the file format.

All ADCs I have looked at document that they can't represent the positive full scale. For instance, for an 8 bit ±1 V ADC, -128 represents -1 V, +127 represents 127/128=0.99219 V. The transition from 126 to 127 happens at 1.5 LSB from the positive full range. 1 LSB difference represents 1/128 = 0.00781 V difference, and not 2 / 255 = 0.00784 V.

But if you actually care about what the voltage (and uncertainty) is, most of this is difference is mostly pointless, you're reference will have a bias, there are linearity errors and so on. 1 LSB will not match either the 1/128 or 2/255, you will need parameters to compensate for it.

As others have pointed out, the 2nd color is not something I would call either blue or green. Except for the first, it never showed anything I would call blue. So really I have told it the border where I still call something green. So is my green your green?

The correct URL is https://security-tracker.debian.org/tracker/CVE-2025-15467

You're pointing to one of the other security issues for which a fix was released today.

It's my understanding that is about generating the .iso file from the .deb files, not about generating the .deb files from source. Generating .deb from source in a reproducible way is still a work in progress.

On iNaturalist there are many people who monitor a specific area like their garden. Those contain links to such projects:

https://www.inaturalist.org/projects/home-projects-umbrella

https://www.inaturalist.org/projects/museum-grounds-and-gard...

There probably are a lot more such projects on it.

For the major browsers, this probably makes little difference, but for anything else, this will most likely result in not verifying the revocation status of certificates anymore or making things slower.

As far as I know, most browser vendors already download the CRLs, and then update the browsers based on what they downloaded. For instance firefox seems to be using CRLite. There is a lack of support for something like that in the non-major browsers and non-browsers. The alternative they have is to download the CRL instead of the OCSP reply, which is larger, probably making things slower. Or they could just not check the status, which is most likely what will happen.

CRLite changes the failure mode of the status check, it no longer just ignores error in downloading the status information.

We need better support for something like CRLite.

Is a passkey a software implementation of a FIDO key? Where the implementation could use something like the TPM to protect the key.

Yes, the dates are correct.

C2 is error detection, not correction. C1 is the error correction. I think what wikipedia is trying to say is that the C2 error detection just points out something is wrong, even after the C1 error correction, and so you can't fix it. But a data CD has additional error correction, so it can correct more errors.

An audio CD has 2352 audio bytes per sector. The sector also contains C1 error correction and C2 error detection.

On a data CD, those 2352 bytes are split in 2048 data bytes, plus an additional 4 error detection, 276 error correction, plus some other bytes including an address. So there is an extra layer of error correction.

As one of the other links explains, ripping the same CD on the same drive a 100 time might still not produce the correct rip. Something like AccurateRip works by having multiple copies of the CD scanned, and then voting which one is the correct version.

I forgot that CTDB (http://db.cuetools.net/) exists, which is is an alternative to AccurateRip. CUETools is open source Windows software to rip CDs. Instead of just providing a checksum of the track, it provides error correction information. So instead of just getting that you probably have a bad rip, and keep getting a bad rip, it's possible to correct the rip. EAC has a CTDB plugin that's installed by default, whipper currently doesn't support it.

AccurateRip is not something from EAC, it's from dbpoweramp.

This is based on submission to AccurateRip. As I understand it, it's how many tracks submitted by users owning that drive match the what AccurateRip considers the correct rip.

If you care about accurate rips on Linux, the best tool to use is whipper: https://github.com/whipper-team/whipper. It makes use of the AccurateRip database, which is used to calculate the statistics. I don't know about any other native Linux application that makes use of it. Other tools like cdparanoia, and all the other wrappers around it, just attempt to read it multiple times and still get the wrong result, as the post shows.

I assume that he measured the power consumption himself. You can find a lot of cheap devices that you can plug between your wall socket and the device. They are not usable for measurement at low power. If you try to measure something in the 0 - 1 W range, most just show 0, others even show something like 30 W.

There isn't a "remove result" button. At the bottom there is a "Privacy settings", "How Search works" and "Cached" button, while the screenshot shows "Remove result" and "How Search works".

Having unsuccessfully gone through 2 different procedures to try to remove that page from Google search result, I have little faith that it will work now.

For the torque, you can use a low current using more windings, which has the same effect of having a higher current with less windings.

The acceleration you can reach is mostly limited by the peak current and the force constant, but the maximum speed you can reach at that acceleration is mostly limited by the voltage you have available because of the back-EMF. A simplified formula is that the voltage you need is R * I + v * BEMF. The higher the voltage is, the better the insulation between the windings needs to be. You need to find a balance between the different properties.
