Might as well make a general thread for this.
Article on search engines with their own index:
https://seirdy.one/2021/03/10/search-engines-with-own-indexes.html

I'm interested in making and hosting a curated search engine(hand picked domains to index) with the following feature set:

Site specific searching
Date range specific searching
Exact string mandating
Image Search
Maybe document type specific searching too
Maybe a synonym system

After hours of research, I still have no idea where to start, like whether it'd be better to make everything from scratch, or cobble together things that already exist, and what if anything I'd need to make myself with the latter option. This post pointed me in a general direction >>/ot/36920 but both Solr and Elastic Search seem meant for searching internal text based documents. I found virtually no information about using them in this kind of context.

I'm no legal expert, but I don't think law enforcement actively tracks people, who more than obviously and self-evidently had contact with that stuff by accident. I think they can differentiate between an actual criminal and you, for example. Also, this site has clear rules against CP, so it's blatant that you didn't type in tohno-chan.com into your URL-bar with the intention to watch CP and (as far as my understanding goes), that is what actually matters to the police.
>> No. 3491 [Edit]

Yeah that's my understanding as well. The one thing I do worry is whether there are any "automated" systems flagging you and putting you on a watchlist or whatnot, but I think it's more likely to be done by having some fixed list of "hot domains" rather than actually scanning every byte on the wire (since realistically TC is one of the last places _without_ TLS, so doing so would be basically futile).

If/when IA falls, what do you reckon are the chances/amount of data lost, aside from what they intentionally remove from the archives. Forgive me for my ignorance, but what's there to stop splinter groups from forming with the partial amounts of the data they have access to?
IA could go down or become unaccessible and that would suck, but what I am scared is if that meant any amount of data that is not backed up being lost/deleted, inaccessible to the public or not.
I recall them having some backups internationally, but from what I can tell they all are only partial backups, outdated and stagnant.
If only some benevolent oil barons spent money creating backups of the archive in various countries...

IA has always felt like it was run on tin cans. I'm not surprised this happened, they really don't seem to have much technical competence (for the longest time the wayback machine scraper failed at its basic job and never saved resources like images, this was only fixed in 2017). And of course others already commented that for some reason they seem oddly fixated on trying to poke the law with their ebook lending program rather than shutting up and staying out of the limelight (Anna's archive has already mostly solved the ebook archival problem).

Oh and don't forget that if they aren't brought down by this, an earthquake eventually will: Whose bright idea was it to put their datacenters in a city that's known to be at risk for severe earthquakes? I cannot find any evidence that they've taken measures to seismically retrofit the buildings, so I assume they haven't.

I have a relatively old graphics card laying around, that once broke for a reason, that I don't remember anymore, and since I didn't know what to do, I bought a new one. Years have past and the old graphics card has been collecting dust ever since. Until now, because I want to find out what's wrong and how to repair it. It's an R9 280X, like the one in the picture. While I want to get the card repaired, I see it primarily as a learning experience and as such I don't mind the price of the tools and items needed, exceeding the final worth of it. It seems to be fairly accessible from the outside, having normal screws and nothing particularly hidden.

I knew a guy, a while ago, that could do this stuff, so I'm confident, that it can't be too hard to learn, but I don't do anymore, so I'm asking here if anyone knows how to go about this.

1) How do I learn about this besides reading hardware documentation?
2) What tools (if any) do I need to repair it?

Does anyone here have experience with ham radio (perhaps even getting a license)? I recently stumbled across http://www.websdr.org/ and it's been kind of fun playing around with it, tuning into random parts of the spectrum and catching people's conversations (it's also mind-blowing that we now not only have enough computing power to do the demodulation and signal-processing that used to be done with dedicated circuits directly in software, but that we can do so in real-time inside a browser). Seems like ham radio is a dying hobby these days, and the only people left doing it are the older generations, but the sort of insular culture is also kind of neat – almost like an imageboard community.

Most of the topics I saw being discussed were people talking about their setups, but aside from the communications aspect there's got to be some other cool stuff you can do with broadcast/receive permission for all that spectrum.

https://spectrum.ieee.org/ham-radio was a nice recent article on the current state of ham.

I guess "ham radio" as a community is dying, which makes sense since there are endless ways to communicate these days. Moreover, from a technological standpoint the ability to transmit information over distances via radio is no longer as captivating as it once was, since the Internet suffices for the vast majority of use-cases (especially since you don't need to get a license to experiment with it, equipment is ubiquitous, and development can be done at the software-level).

I have a Baofeng GT-5R (which is basically a copy of the notorious UV-5R), but I never managed to receive anything with it, or at least no voice, which is what I hoped for. From my understanding, you need to connect to a repeater, to receive anything, so I tried programming it manually, to connect to it, but it didn't work and a second time I tried doing it with a programming cable connected to my computer, but it didn't work out either (apart from changing some trivial settings). I used a software called Chirp for it.

I probably agree with this Anon's >>2131 notion, that it probably sounds more interesting, than it really is. HAM Radio is heavily regulated, very expensive and at the end of the day, when you jumped through all the hoops, you just end up in a glorfied audio call, where you can say your name and location. Maybe there is more to it, but I think at that point you'd have to either spend an inane amount of money and time for it or do it professionally.
>> No. 3455 [Edit]
>>3454
Yeah the FCC restriction that HAM communications be "in the clear" kind of makes things boring.

It seems most of the recent attention in the radio-space has been around LoRaWan (using the unlicensed 900MHz band), since it's not subject to such constraints and unlike 2.4GHz the 900MHz frequency gives you enough range to do cool things.

>type of attack that you believe TLS will protect you from
In the developed world I think it is most likely going to be limited to sniffing.
>there are no non-public messages
TLS provides padding of data, so AFAIK there is no plausible way to tell that you made a certain post just by observing the encrypted stream of data.
>> No. 3427 [Edit]
>>3426
>TLS provides padding of data
No, only tls 1.3 does, with an optional extension (I also don't know whether this is actually used in practice). Padding also only reduces the granularity of content length that can be observed (because there is an inherent tradeoff between padded cipher text length and overall throughput). Moreover, you are completely forgetting about the whole suite of traffic correlation attacks that are trivial when messages are public. Even if you use DoH and use TLS with ECH or ESNI (which are both perpetually in draft state, and currently not widely deployed), the destination IP is sufficient to deduce the site you are visiting (even on "shared host" sites like TC.) From there, correlate packet timestamps with post time and content length again allows you with high probability to attribute a post to a given source IP. That's not even mentioning the wealth of metadata present in the TLS handshake itself (even with ECH, other side-channels like the cipher suites the client/server negotiate, packet latency, etc. make targeted deanonymization feasible).

All of these are table stakes for the adversary you are concerned about, because they are pretty much the same techniques use to deanonymize TOR traffic.

Seems TLS 1.3 padding is not used much in practice (based on anecdotal experiments in wireshark by others). Go doesn't support it either [1]. Makes sense since no one wants to waste bandwidth for a feature that's made pointless by the bevy of other side-channels anyway.

>admins of many small imageboards are more trustworthy than an average ISP.
That really doesn't matter if things are not self-hosted. TC uses DreamHost I believe. They are based in LA, the implications of which should be clear. In fact apparently in the past they've already had a warrant to hand over all info.

OK you win. The only more or less valid point I have left is that targeting plain text traffic is sweeter than elaborating with timing attacks.

A thread to speculate where technology is headed.

I'll start by asking whether you think PCs have a future. You may have heard that Microsoft is planning of making Windows 365 available to consumers. So thin clients that rely on an internet connection to be used, will probably become more mainstream at some point.

Right now, there's a few things I can think of which would prevent thin clients from rendering full-fledged PCs from becoming "obsolete". Latency being one obvious barrier, but internet speeds are getting faster.

There's also the issue of gaming. While there is a niche of people who expect 120 fps at a minimum, that might not be a large enough market to keep PCs afloat. Maybe normal people playing on consoles, and a hostile landscape, will kill off the temporary boom that PC gaming is having.

Lastly, a lot of companies would get fucked over if thin clients became the norm, like ones that specialize in certain PC parts(Crucial, AMD, Noctua, etc.). There would also be no justification for higher-end hardware in stuff like laptops.

What do you think?

The point I think he's making is that there's way more more "semantically meaningful" information handled by the client (i.e. text buffers, codebase metadata, etc) with the "LSP" (specialized client + RPC mechanism, really) approach, which might make it easier to leak remote data (either intentionally or, say, by local caching and whatnot), as opposed to the desktop streaming approach, where all you have is a bunch of pixels from your remote screen and all of the meaningful state is on the remote end.

At my dad's job, he uses all kinds of software, not just an IDE. Database managers and all kinds of built-in-house stuff. They also use Excel files stored in Windows network folders, and stuff like that. None of that can be accessible from his host OS.
>> No. 3240 [Edit]
>>3238
Yeah that's fair, although I find it hard to imagine a threat model where an adversary can access in-memory text buffers but wouldn't be able to just capture the entire framebuffer (thereby accessing remote content). Usually the threat model with regard to thin-clients for FAANG companies is to avoid any code hitting disk, which is fairly easy to guarantee even with an LSP-type approach.

A few things have come out in the months since this thread was made. First of all, ARM CPUs are coming to the mainstream. Apple has already made the transition, but now both NVIDIA and AMD are planning on getting in on it. I think this will constitute a new "era" of personal computing, ending the one that started with Windows XP.

On the software-side, compatibility with win32 applications will become less emphasized, and maybe even gradually phased out. Compatibility layers are bound to be imperfect, and most users don't care enough about that for it to affect their purchasing decisions. Web-based applications have become popular even in the corporate sphere, and while there's a few irreplaceable professional-applications, all of those will get ported. On top of all that, emulating a windows 7 machine is becoming increasingly trivial on modern hardware.

On the hardware-side, lower-end GPUs will probably go extinct as iGPUs get better. Power efficiency might become more emphasized, which ARM contributes to. Those 1300W PSUs might disappear. Socketed ram might also go extinct because there's performance and energy advantages to coupling it together with the CPU. Most people upgrade everything all at once anyway. It really depends on how AMD and NVIDIA decide to handle desktop ARM.

The gaming industry as a whole doesn't seem to be doing too well. Games have become too expensive to make, and they're kind of crap now for the most part. I don't know how much interest there is among the general populace in non-mobile stuff. This will affect PCs too, but I'm not sure how and to what extent.

Hey everyone,

I just read this cool article (1) about mulberry fruit extracts and how they might slow down skin aging, thanks to their polyphenols. It's on ScienceChronicle.org and talks about how these extracts help fight glycation and boost antioxidant functions.

This got me thinking – what's the real deal with polyphenols and anti-glycation? I mean, are all polyphenols equally good at this, or do some work better than others? And does their structure make a difference in how well they stop those AGEs from forming, especially for skin health?

Also, is there any debate among scientists about how effective these polyphenols really are? I’m curious to know what both sides are saying.

Would love to hear your thoughts or any cool studies you might know about!

I can't tell if this is an absurdly high-effort version of the "miracle berry" spam ads, or an actual discussion topic from someone with biochem experience.

Unless there's other biochemists lurking here I think you might have to break things down for us layman a bit more: I have some vague knowledge of polyphenols being good antioxidants, but beyond that what's the particular role between anti-glycation and skin health? Is there a particular reason you're interested in skin health (it seems like other factors like metabolic health or basically any other body part would be more substantive).

You may actually be right, that "sciencechronicle.org" website seems a bit suspicious, it basically has a pagerank of 0, not having any inbound links from a reputable site. And the only links to that site that exist on the web are either from random spam domains, or from other chans/forums, which use the same copy-pasted text as OP.

The thing that confuses me is that the site itself is fairly "clean", it doesn't have any trackers besides google analytics, no ads from what I can see, minimal JS. So what's the point of this: high effort SEO farming? I'm guessing the article may be auto-generated, but it seems to have valid relevant citations which is not really something that LLMs are known for.

Well, I want to wanna learn. Blows my mind reading some of these threads where it's like I'm reading another language. The whole thing is overwhelming, which only intrigues me more. How did you get started with coding/internet languages/programming. I don't even know what to call it, see? Where does one begin? I remember buying a C64 a few years ago with the goal of learning basic and creating a very simple game like the protagonist in RPO, but I gave up pretty fast and sold the god damn thing. Bought a Vic-20 too for some reason, but I still have that. Think I was just obsessing over old computers at the time. Had some experience with python in my physics class, but that didn't last long cuz I dropped that major the next semester lol.

Please, I at least want some kind've a general idea about what the fuck you guys are saying sometimes. It's so intimidating, but fascinating. Like I know another reality exists within my own, but I can't perceive or interact with it in any meaningful way. Where do I start?

You mean restoring vintage computers? There's a decent amount of people into retrocomputing (not on TC but elsewhere on the internet), and you don't even necessarily have to know anything about programming to do that. In fact having some soldering knowledge will probably be more useful since you'll probably need to replace bad capacitors and such. But I'm not sure what people do with them once they get it running.

I wouldn't say I'm interested in a particular subfield more than any other, I find all of them interesting and will eagerly seek out opportunities to learn more about them.

>What interested you
I don't really remember. I think it's just that I spend a lot of time on the computer, so it was a motivation to know enough to be able to have unilateral control over my environment. And to be able to confidently mess around with things, you need to know how they work.
>> No. 3286 [Edit]
My issue with programming is that I am extremely stubborn and can't focus on things that I have no interest in. So, in python class for example, when they tell me to code something that figures out how to perform some sort of function based around division of numbers or whatever, I just lose interest. If the language were written in such a way that classes, objects, strings etc were called "swords", "spells", "dragons" etc I would be more mentally stimulated and pay attention...
