some of the heyuris are building a new imageboard from scratch

what are good features to include?

An imageboard doesn't need "features." Tinyboard/Vichan basically nailed it. The edit feature available on TC is perhaps the only real improvement that upstream tinyboard is missing.
>> No. 2204 [Edit]
All you need is text + file upload. Other stuff is bloat that you can tack on later.
In regards to coding one, HTML5+CSS has actually helped quite nicely. Use custom HTML tags and CSS selectors and things will be much easier.

Gurochan is back and it's being hosted or something like that by the same Russians as heyuri, kolyma network. I found this cease and desist letter they sent to "guroboard", since kolyma apparently now owns the tradmark gurochan. Don't know if this is real, but it's weird.

Far too much of the stuff I need sporadically requires js for me to disable it automatically. I used to have it disabled, and once had to wait 6 hours to make a financial transaction because some security authorization component on a website needed it and that not working tripped a wire or something.

Firefox ESR has been pretty bad for a long time now, but I'd still rather use it than Chromium. One thing that concerns me about switching to one of the forks is whether they get timely security updates.

I do. Disabling JS breaks many websites, which is a pain. >>/ot/33997 and >>/ot/37266 have been pretty useful, even though some functionality is still missing or partially broken with them. The public Invidious instances in particular tend to be somewhat flaky, which is why I hesitate to link people to them.

Couldn't you disable it for general web browsing and only enable it for financial stuff? You could set up separate browser profiles for this.

I use pale moon and switching pale moon profiles is a pain and requires restarting the browser or screwing around in ways that break its interaction with other apps.

Cool I didn't know about teddit. There's also "old.reddit.com" which they still seem to keep alive: it preserves the older layout and works mostly fine with JS disabled. Although they've been caught doing shady stuff before [1] so I should probably switch to that.

>Couldn't you disable it for general web browsing and only enable it for financial stuff
Not him but I think he was saying that he didn't even know that the site required JS to avoid tripping the fraud detector or whatever, so he didn't think to enable it. I've noticed this a lot – sites just break in random ways, and if I hadn't used them before disabling JS then I wouldn't even have realized that some dropdown or feature was supposed to exist. It'd be nice if all sites at least supported the noscript tag to let you know that some features are missing.

Thread for general discussion of p2p networks and protocols.

Here's some uncharted territory: there's apparently some Japanese p2p projects. 新月 (掲示板) is a BBS, Perfect Dark and Share are file sharing services. Perfect dark also has a message board system. Does anybody use these? Are there others?

Legal questions are fairly local, you can't give a real answer without having at least a specific country, even a specific state, in mind.
Very generally though, there needs to be intent to commit a crime. And since there's legal eepsites (most of them, even) the more act of using i2p cannot be intent.
And to even get there, they'd have to know what content you're routing in the first place, but that's heavily encrypted.
>>2185
I2P does not itself contain data storage. There's Lahoe if you want that, but I'm not sure it even works anymore.
>> No. 2187 [Edit]
>>2186
By distributed data storage I meant stuff like torrents.

Zeronet, perfect dark and the work in progress safenet(maidsafe) are entirely reliant on distributed storage.

I remember hearing stories about people who ran a Tor exit node and were contacted by the three letter agencies a few times for suspicious activity, but upon seeing that they were only running an exit node they were off the hook. I don't know how true those stories are, and running entirely within i2p is probably safer than running exit nodes. I think the risk is fairly trivial though since I haven't seen any stories of people arrested for using Tor for legitimate purposes, and i2p is even more obscure.
>> No. 2189 [Edit]

>Tor exit node
That's why you should run hidden services and avoid using Tor to browse other websites. However, there's a guide about that on the Tor project website.

What are your thoughts on alternative web protocols like Gopher and Gemini?
We're living in the dark ages where modern webshites are obsfucated behind multiple scripts and horrible web designing.
>> No. 2174 [Edit]
My thought is that they have low adoption rates, which means standards that advance at the pace of a dead snail. People fill their sites with slow, pointless/malicious scripts and bad design because they can. People can also choose not to do those things. "Quality" via stringent restriction is unecessary and misguided.
>> No. 2175 [Edit]
I've tried gopher before, and it really does all it needs to (there's even an imageboard available, 1436chan, gopher://khzae.net/1/chan).
I like how it forces everything to be usable be text-only browsers, text being the universal interface.
Making a gopherhole is also fun because it's so easy. It is what the web should be.
If Gemini is pretty much that but in encrypted, then I'd probably be on board as well, but I haven't tried it yet.
>> No. 2183 [Edit]
>>2173
I really like Gemini. I believe Gemini has some kind of scalability issue however so it could never become a replacement for HTTP. Nonetheless, I intend to use it myself at some point. I do like the idea of forcibly keeping things simple.
>> No. 2385 [Edit]
It's more an issue of content, not protocol, so I don't think alternative protocols will be that useful to solving this. That is, you can choose to make plain-text no-js sites served over http but not many people do so nowadays. Although I guess the giants are trying to stamp out plain http in favor of http over tls which seems pretty pointless for most read-only content.

(for some reason can't edit, so apologies for double post).
Besides the conclusions that don't follow from the previous statements, you also have patently false statements such as "time is space" (while they're linked, sure, they're not interchangeable as clearly seen from the fact that the minkowski metric has a different sign for the time dimension than it does for space).
This seems more like the work of a crank than something substantive.

I think it's because I have cookies set to expire pretty aggressively, which invalidates the default generated password. I should probably write a userscript or something to automatically set the "postpassword" cookie to a fixed secret value.

Hm you might try compiling from source and see if that fixes it. Alternatively if there is indeed a bug you could try compiling with debug symbols if needed and stepping through with gdb (or just looking at the symbol dump) and seeing what's causing it to segfault.

Another option might just be to find where the preferences are stored (probably some dotfile in the home directory or near the binary path) and modifying that directly.

I had some linker errors trying to get this to build on Linux. Seems like some GCC defaults changed since this was working to disallow for some undefined behavior, which MaCoPiX needs to be patched for. In the meantime, it can be worked around using `make LDFLAGS=-Wl,--allow-multiple-definition` for the make step.

Greetings.

I recently noticed that one could express a polynomial in terms of combinatorials and so I am curious as to how far one could go with this.

My requests are:
1) An expression of n^4 purely in terms of combinatorials
2) A method for finding these combinatorial-expressions
3) Clarity regarding what the term is for this field of study my question would fit into (if there is one)

I notice Pascal's triangle appears consistently (albeit with the rightmost '1' cut off) so perhaps, keeping the positive-negative alteration in mind, the n^4 combinatorial-expression is actually quite predictable but I have yet to test this and to be honest, I'd rather find a method than apply what I predict could be the cheat-sheet.

This just looks like sequences and (finite) series, though.
>> No. 2045 [Edit]
OP, you did well in asking if there was such a subject beforehand. Lately I was asking myself if there was something on sequences that are like arithmetical progressions, but with a different ratio between every number. I research deep in every possible related topic and couldn't find anything, even describing the problem didn't help. I ended up finding some formulas of my own, in the end, and was even going to post them here and ask about, but eventually I found they actually exist and are called quadratic sequences. There isn't a lot about them, though. The existing formulas are very different from the ones I made, and it appears that there are (as I suspected) even higher orders of magnitude, like cubic etc. What do you guys think of this whole thing?
>> No. 2046 [Edit]
>>2045
I think you can just generalize everything by writing it as a recurrence relation. For a quadratic relation we know that we must have

d(n) = f(n+1) - f(n) = an + b, which implies that f(n+1) = f(n) + an + b.

Now for the particular case of quadratic sequences I think finding a general formula for the nth term is relatively straightforward because we know how to do sums of arithemtic sequences, so you can apply this to find d(1) + d(2) + ... + d(n) which immediately gives you a formula for what f(n+1) is. Same thing applies for "cubic sequences" as well and so on since we have nice closed form solutions for those.

>> No. 2038 [Edit]
Hard to implement cleanly, since you'd probably have to double the thickness of the display part. Maybe with the new fancy paper-thin/foldable displays it's possible, but it doesn't make sense ergonomically since it'll be off-center.

That'd be neat! And the vertical real-estate would be very useful. Tangentially I don't know why almost all laptops are 16:9, even though 16:10 gives you that extra bit of valuable vertical space.

Hello, this is not a shill post. So I decided to create my own chan in python as a hobby (using the flask library) and this is what I have come up with so far. Just give me feedbacks here in this thread or there.

Currently you can only upload jpeg , jpg , png , gif below the size of 4mb.

Boorus are more of a mass collection site with little to no quality control. I'm thinking of a place where people post the cream of the crop, not just dumping images for the sake of it but sharing things that hit all the right strokes for them. Maybe a scene in an anime which spoke to them, or a single piece of erotic art that they could get off to several times. Also, I'd like people to have discussion about those images, albeit with the stipulation that EVERY post would have to contain an image. I don't want something like 4/h/ where half the thread is people shitposting or arguing without posting anything.

From the classical point of view, it is natural to assume that everything that happens in our world must have a reason. This reason may be hidden, unknown, but it must be; it is this consideration that underlies attempts to create a more detailed theory of the phenomena of the microcosm. But from the point of view of conventional, orthodox quantum mechanics, the theory of hidden parameters is impossible, if only because it does not have its own subject "behind the scenes" of quantum phenomena simply, according to quantum mechanics, there is nothing.
Is quantum indeterminism the absolute truth? I quote from Paul Dirac's book the Directions in Physics: "I do not rule out the possibility that Einstein's point of view may be correct in the end, because the current stage of development of quantum mechanics cannot be considered as final. There are many unsolved problems in this theory. Modern quantum mechanics is the greatest achievement, but it is unlikely to exist forever. It seems to me very likely that some day in the future there will be an improved quantum mechanics, which will contain a return to causality and which will justify the point of view of Einstein. But such a return to causality can only be possible at the cost of abandoning some other fundamental idea that we now accept unconditionally. If we are going to revive causality, we will have to pay for it, and now we can only guess what idea should be sacrificed."
Is this question open today in the scientific community, or does everyone believe that if Bell inequality has not been solved, then hidden parameters do not exist?

Viewing the universe as a cellular automaton seems pretty neat, and there appears to at least be some people [1] working on this approach, reconciling the results with the seeming implausibility of the conspiracy that initial conditions and determinism always conspire to result in violations of Bell's inequality.

I don't have the depth to go through that paper though so I'm not sure how valid it is.
