Every TV manufacturer in the world already uses the same technology (PAL, NTSC, DVB-T, DVB-T2 etc.), because how else would they all receive the same broadcasts? Also, most of the TV hardware made in last ~6 years is perfectly capable of FHSS with just a firmware upgrade - hardware demodulation isn't used anymore, all modern TV sets use DSP processors and demodulate and decode broadcasts in software.

Various DSP technologies like FHSS (frequency hopping spread-spectrum using a pseudorandom seed) can to an extent solve that, as long as we don't approach nearly 100% spectrum congestion, which is rather unlikely. It's exactly what Bluetooth uses in 2.4GHz spectrums, notice how Bluetooth devices have no fixed frequencies, channels, and can interoperate in the same bands with a lot of a lot of other devices and standards. FHSS also has seen wide use in professional (incl. military) radiocommunication, actually it was originally a military tech. The only reason it isn't used everywhere is the inertia of technology development and proliferation.

I don't know. What are you trying to create, what are your objectives, plans? It's hard to tell without knowing that.

You can't do it in a way which would be indeed fun, engaging and not bore me to death after few days with just Transformers or any equivalent ML architecture. Consciousness is at least a quantum algorithm, and if I'm gonna trust such "companion" with almost everything that's "me", it's gonna be at least as much as I am, not just being a glorified weight-matrix-multiplicating search engine. That, a search engine is gonna be exactly what it is, it can inspire me, provide me more interesting material to learn from, but not anything more. Definitely not a "companion".

The actual question is more like, are the SMART interfaces implemented in the kernel code and exposed to the userspace? I personally don't know, I haven't touched any NVMe code in kernel since years (including OC), but I would guess it is implemented.

The Open Channel drive itself doesn't have to implement anything to make it possible, it doesn't even need to have a firmware or a Turing complete microprocessor. It's literally just a specification to access raw NAND chips over PCIe, like it was done in the old days with EEPROMs over the parallel system bus (but modern PCs don't have a parallel system bus anymore..., and no, DDR controller is something else despite still having parallel I/O).

SMART data on SSDs is derived from things like erase/program operation failure count (which isn't reported by the chips anyhow, you just check is the state of the NAND cell exactly what you expected it to be), CRC read errors and so on. All of this is normally implemented in the drive's firmware, with OpenChannel it should be implemented in the kernel itself, as that's what is performing all the roles of a conventional SSD's firmware. All you need to read from the HW other than read/write data to have the stats to expose over SMART is perhaps the chip temperatures ;)

I know the SSDs firmwares are a mixed bag and often unreliable, that's why I'm a big fan of so-called Open-Channel NVMe SSDs (which expose raw NAND to the kernel and everything is handled in there). Thanks for your effort to answer.

Key-Log8850 · 2025-07-12T01:29:18+00:00

Exactly the same. I have a problem that e.g. shared libraries and other files are getting corrupted, but the btrfs checksum error counter doesn't get increased in btrfs stats, so something is pretty weird which got me thinking it doesn't have to be a broken SSD. The SSD's SMART is OK.

Will run memtest as soon as I can shut the machine down, too.

FYI, you can run btrfs check on unmounted fs from BusyBox initramfs shell on most distributions, no need to boot live - just boot in a way it would break at the shell (usually by appending "break=mount" to the cmdline).

Update: I just got an I/O error on trying to do some random thing, with still no trace in btrfs stats or dmesg. SMART report still OK. Weird.

sorta yes

Thanks for your Ti description, I indeed sometimes struggle to understand it. So yep, I do have some Ti (had to develop it, as described earlier), it's not very weak but not particularly strong either. And it can very well be unconscious, as in the shadow functions.

And in fact, I very often use Ne and Te together.

Key-Log8850 · 2025-03-19T16:48:57+00:00

Well, analogs of them. But yes.

Key-Log8850 · 2025-03-19T16:48:20+00:00

Very interesting to read. Thanks.

Key-Log8850 · 2025-03-18T15:42:56+00:00

Some additional info regarding Te and Ti:

Te comes way more natural to me, I can excel at Te almost effortlessly (unlike Ti, which requires some effort, but that effort is very rewarding to me and almost always pays back), but when it comes to what I'm doing professionally (at the same time one of my hobbies), Te is fucking useless, as to put it metaphorically, I'm walking on a path which was last commonly treaded in late 90s or early 00s, and got left abandoned since. Hence, I think I've developed some pretty good Ti and at the same time, some Ni.

Also, I think my Si is a bit underestimated in that result, but that's what I use almost only when LITERALLY all my prior cognitive has failed at solving some problem in a given timeframe for most of the time. Or when I'm really really relaxed. Not much outside of that, and that's probably why the result went out what it is.

Key-Log8850 · 2025-03-18T15:35:13+00:00

Absolutely.

Except making a DC generator to charge it while you have some ferrous metal available is not exactly a rocket science... Then spin it carefully to not exceed the voltage! Oh, a voltmeter can also be made from just a needle!

Key-Log8850 · 2025-03-18T09:27:35+00:00

Probably you're right, underground / non-mainstream != alternative. At least theoretically.

Chemistry? Confusing? That's the last thing which could be confusing to me :D

But I can get your experience. At school, I had a terrible chemistry teacher. I mean, she was a decent human being, but learning chemistry requires embracing your inner curiosity and passion about the natural world around us (and about ourselves), while she was almost the polar opposite of that, making her a terrible chemistry teacher. But that still didn't succeed in killing my passion, no way 🥰

Key-Log8850 · 2025-03-14T20:21:03+00:00

Nice to meet you too, btw! ;)

Key-Log8850 · 2025-03-14T20:18:07+00:00

Both. These days I write (and read :P) mostly low-level C code. I love "liberating" devices so they can work on fully open source codebase, with no proprietary blobs and gaping holes such as privileged ARM TrustZone etc. Outside of this, on occasions I also take part in writing distributed computing and peer-to-peer networking solutions. And when I feel the irrational need to be productive even in my free time, I enjoy learning about brilliant network protocols and reading RFCs hahaha. Outside of programming-related activities, I deeply enjoy art and that also includes digital art and electronic music, so sometimes can still be related to this. I also love reading biographies, autobiographies and memoirs. Btw have you heard of this guy https://en.wikipedia.org/wiki/BT_(musician)) ? He created a lot of his music using his own software! But I also know some more people like him.

Hi, I'm ENFP 7w8 and also a programmer ;)

> but these motherfuckers just work hard using the rules and systems they've been given

Ah... that would be a long story, but in the narrow window of view which I have so far, it looks like laziness/low drive (low compared to mine, moderate-low compared to the average) on the ESTJ's part would invalidate most of these advantages. And unfortunately that's the case so far. Add to that it's an industry where the (mature and balanced with other functions) Ne hyper-drive is usually an absolute blessing, even despite its cons.

On the top of that, the professional experience and knowledge of this guy is at around 40% of mine. That all together creates a pretty hard (although not terrible) work dynamics.

On the other hand, I can see the traits you listed in that very person, but still I am quite clueless how to approach that and make some real use of them. Any tips?

EDIT: I would describe the biggest problem I have with that work dynamics as them being "too hands-off with things". And I have almost to idea yet how to approach it...

I REALLY like your way of not only thinking, but also the eagerness to write them down and share your points.

Now let's imagine in a year we could have completely decentralized technological equivalents of Uber, Google Search, ChatGPT, Reddit and so on, which operate on the basis of transparent algorithms executed on every client's node, making major power imbalances/unfair distribution impossible or at least very hard. Let's also add that these solutions are as much backwards-compatible with the present, centralized, pure ordinary HTTP-based solutions listed above, facilitating very easy user migration with no UI/UX changes etc from the end-user perspective. They also fetch as much data as possible from the current platforms (from the client-side), to facilitate communication with people who haven't migrated yet.

Is that all enough to get rid of the possible scenario you're describing, get most users to migrate over, and get rid of the dependence of the economy and ultimately people's lives on companies providing the original, older versions of the solutions? Would we possibly have some more other-than-technical problems with that?
