how's that "to the moon" going for you buddy lol?

I can't even reliably circumvent capitalist banks with this shit because they ban your ass as soon as they see a "suspicious" activity

I have money essentially stuck in the computer, anything more than paying bills and your bank will ban your ass for suspicious transactions from randoms

the only way is to bend the knee and go to backdoored regulated exchanges

Attachments can have another special column: a bigint representing a 64-bit unsigned integer, that we compute using a perceptual image hash algorithm (there's libraries to do this). We can add a special index on this column, using the bktree postgresql extension, that will let us compare the distance between these numbers efficiently, bit by bit (called the hamming distance).

CREATE INDEX attachments_phash_bktree_index ON attachments USING spgist (phash bktree_ops);

This column will let us do reverse-image search on similar images.


Attached is the full sql file, where I have added some users and granted them permissions

Next I'm going to get postgREST serving locally on port 3000. Postgrest will automatically create a REST API for our database. (https://github.com/PostgREST/postgrest)

Then I can build a script that will read in the board's json api files and populate the database. I prefer to just hit this REST api than write database queries out as strings in some way, I've tried different ways of doing it, using and ORM or a domain specific language and using postgrest was the most pain-free.

I will also throw this repo up online here: http://git.leftychan.net/0/chan-delorean
(or here http://git.wz6bnwwtwckltvkvji6vvgmjrfspr3lstz66rusvtczhsgvwdcixgbyd.onion/0/chan-delorean for onionfans)

I've also written a postgrest service for nixos if you want it: https://github.com/towards-a-new-leftypol/devops/blob/spamnoticer_deploy/nix-support-production/postgrest.nix

I wrote some more glue code to shove all of the posts from the board into the database, by simply reading the json api files, transforming the data structure slightly and passing json to PostgREST.

To not take too long I shove all of the posts on one board into the database at once: the sql code takes an array of all the posts, does a SELECT to get the ones that exist already, inserts the ones that don't yet exist, and returns all of the internal post ids. This is quite boring, you can go read the source if you care, but it takes about 2 minutes to save leftychan.

I have monthly snapshots dating back to around the bunkerchan split, so I ran those through the script as well. Perhaps not every post ever posted is there, but I have around half a million posts. Now we can get to the fun part of attempting to query the database for what the board looked like at an arbitrary point in time.

>>12585
that is impressive work

>>12586
👍 Thanks anon! There's more:

I want to see the board as it was a year ago. I need to get all of the threads that were on the board, at t = (now - 1 year).

Threads are ordered by bump time. We need to get the first, say, 400 threads if you order all the threads by bump time.

In lainchan each thread has a bump column (threads and posts share the same table called posts_a or whatever), which makes it simple to get the current top threads, but it doesn't help us calculate what the bump times were one year ago.

So first I recognize that a thread's bump time is just the time the most recent post was posted to that thread.

Maybe I can use SQL's aggregate function to get the MAX post creation time, if we group the posts by their thread_id. Then, since I have indices on the creation_time and thread_id columns, (and another index on both), if I limit the number of threads that I want then hopefully this won't be slow:

SELECT
threads.thread_id,

>t this point I don't know if you are trolling
I'm not trolling you. I get your point, a bunch of radlibs blew a fuse over geopolitical events and began screwing with software packages. And you want to yeet them because that's a breach of trust. I also understand that for this particular case it's relatively easy to zero in on who's doing this, and nip it in the butt.

However I'm also thinking about the general case. We'd be introducing the principle of discriminating based on political affiliation. I would like to avoid this kind of stuff. I would much prefer to have a politically neutral purely technical solution. I don't particularly care about what political or philosophical views some programmer has, as long as the program they make is good quality and does not include malicious features. If we could find a way to make some kind of automated code-audit-system that makes it sufficiently difficult to spike a software package in this manor, we could screen out bad actors, without having to deal with politics and all the bad blood that brings.

Libs banned Strelok from the app store too so now it's hard to find an apk without using yandex and a translator. Fag dev couldn't monetize it so he shut it down. All the more reason to go open source. We desperately need a FOSS app to estimate holds!

So apparently that was a "ballistic calculator". I've only heard that in the context of Naval artillery. Your hobbies must be wild.

i tried searching for this online but, i got nothing, what's a "hold" ?

>>12565
some cool afghanistan boomers at my USPSA and they taught me some long range stuff too with their Rem and vortex. You can use the app with your caliber barrel length etc to calculate what hold to use on the reticle. You can also turn the top turret to adjust for drop. It's nicer than other apps because it has a lot of reticles pre-loaded and can select between mil and moa dots. Boomers I talked to like mil because you can estimate range based roughly on shoulder width and height. They had it in a notebook with a table for it but it was something simple. Go talk to boomers anon they have a lot to teach and no one to listen.

Reddit upvotes go into your Karma score which is exactly the technocrats' social credit score mechanism of fascism.

Reddit is run by alphabet soup (and so are both leftypols)
Alphabet soup is the result of government because centralization of power makes it really easy for psychopaths to take control and push their agenda.

Why do you think reddit karma is reputation? It just tells you how many internet-points somebody got, it doesn't tell you what they got it for.

If i tell you Fred is good at math, and then 10 other people confirm that they too think highly about Fred's maths skills, then Freds gets a reputation for being good at maths.

>>12506
>Reddit upvotes go into your Karma score which is exactly the technocrats' social credit score mechanism of fascism.
The problem with reddit is that it is fully centralized so the reddit servers have ultimate control over your karma. Even if a million human beings saw and liked your post the server can give you zero karma because fuck you.

Distributed reputation systems like nostr are not necessarily a bad thing though since public key cryptography makes it impossible to forge and you can use a blacklist/whitelist to disregard the votes of bots and shills and people who don't matter.

>like letting you talk directly to various characters.
Great, let humans unlearn the ability to have fictional conversations with fictional characters in their own mind (aka daydreaming) or roleplaying characters in chat or LARP and replace it with a bot that doesn't even understand what it is talking about and whose every word is controlled by some crazy transhumanist silicon valley dipshit nazi eugenicist technocrats.

The oculus rift is not AR nor is it capable of it. What Apple's headset will do is superimpose images on top of your real vision and perfectly track it in 3d space.
A real life example is how they put graphics on football fields in live action video of games. creating the illusion that the graphic is really painted on the ground.
But this headset will go far beyond that. Imagine being able to complete complex tasks far beyond your skill set because you can have the headset walk you through it as though a master technician were present.
Imagine looking at a car engine and then having wrench appear on the bolt you need to loosen, turning in real time in front of you as if it were being demonstrated to you in real life, and then every step in the process illustrated to you in the same way.
And like I said, humans remember things spatially the best.
Imagine being able to store your computer files by placing virtual folders in your real life bookshelf.
I know it sounds silly but it's going to expand people's ability to recall information exponentially.

>>12458
Apple's head-set might technically be capable to do all those things, but Apple will never let that thing become a sufficiently open platform for any of that cool stuff to happen.

>Imagine being able to store your computer files by placing virtual folders in your real life bookshelf.
Especially this bit, you'll have to jailbreak that thing and install some kind of gnu linux OS on it in order to experiment with cool user interface concepts. Apple will just implement a few hand-motion tracking gestures derivative of touchscreen gestures for a slightly modified ios-UI and call that revolootionary.

>>12459
>Apple's head-set might technically be capable to do all those things, but Apple will never let that thing become a sufficiently open platform for any of that cool stuff to happen.
They already demonstrated this in their ads. None of this requires an open platform.
>Apple's head-set might technically be capable to do all those things, but Apple will never let that thing become a sufficiently open platform for any of that cool stuff to happen.
It's in their ads that this is what it will be able to do. You'll leave something virtually on your coffee table and it will remain there when you boot up the headset again.
They showed some watching television and the television remains fixed in the middle of the living room as a the person gets up.

>>12459
>Especially this bit, you'll have to jailbreak that thing and install some kind of gnu linux OS on it in order to experiment with cool user interface concepts.
Why? The whole point of this headset and AR in general is to present information completely in 3d. You'll be able to walk around an object. Several doctors will be able to examine a 3d scan of your body at once.
We loose an incredible amount of information when you present it on screens, I'm telling you this will be a watershed. Tons of things will become obvious that were never before. Kind of line how scientists argued whether horses galloped with all four legs or two at a time. It seems so obvious now but before movie camera we could never prove it.

Rossmann had a doomer-pill moment, he worries repair could be going away and "undo his legacy"
https://farside.link/invidious/watch?v=oMPxr7I90JM

His argument for this is that he thinks that machine-capital for producing tech-gadgets will get optimized to the point of being fully depreciated after a production-run is complete. He thinks that this would negate the economic viability for making spare parts of letting the production machine run a little longer because parts can be sold for profit as well. However most production machine-capital isn't product specific anymore, save for a few specialist components like plastic-molds. Most of the stuff in a production line gets re-used for other stuff once a product-batch has completed. There are costs involved in puzzling together a modular production line, and because of that the economic viability to getting extra profits off a line from spare-parts remains.

Repairing tech will not go away, because it costs less labor to repair than to build new. You have to consider more than just the last manufacturing step. The entire supply-line that precedes that last step does not have to spring into action if you repair, but it does if you build new instead. The age of just throwing shit out and buying new, even for tiny defects, was only viable because for a limited time there was near endless cheap labor in Asia.

Repairing also reduces waste-streams and resource consumption. The cost of those are going to go up, new resource extraction will get more expensive, considering that you either have to dig deeper or go into space, recycling also isn't free and it's probably going to get more expensive to throw shit out because dealing with trash gets harder too.

If you look at the technology design from the perspective of a physicist, a machine is a collection of matter with low internal entropy. If you use the machine the internal entropy increases. If you don't want the machine to fail, you have to somehow remove "chaos-energy". That can be done in the form of cooling. But one particularly effective way is to replace wear-parts, where the "chaos-energy" is concentrated into.

There are structural developments that favor repair too. The biggest hindrance for repair has always been managing parts logistics, but computer-data-bases and object-storage-automation have removed that hinPost too long. Click here to view the full text.

good job united states for forcing diversity in the chip market. if china figures out how to produce, for example, the equivalent to a gtx 1050ti for cheaper and cheaper and releases it on the global market, it will fuck up nvidia dominance and force them to lower prices thanks to laws of supply and demand. I really look forward to it, honestly.

Nvidia, Ati/Amd started out making cards for gaming and then later transitioned into server/supercomputer compute-cards.

China's GPU makers had the reverse development of western GPU makers. They started out with compute-cards and they are now trying to also do gaming cards.

While you are correct that they will relatively quickly become price competitive with western offerings on a bench-mark performance basis because the compute-market is hyper competitive, game compatibility and driver quality will take a very long time. It requires cultivating a detailed understanding of all the game engines.

Go look at old forum posts of people trouble shooting game compatibility and driver-bugs to get an idea what it's gonna be like. I think that chinese Gpus will become an option for people willing to put up with that stuff.

>Isn't there a way to do quasi invisible encryption that looks like random unused data ?
There are plausible deniability tactics that you can use, but they're so niche and so restricted, that you'll basically have a machine for single use. Not only that, but if the bait system doesn't look like it's used, then they're also going to suspect something. If it's serious enough for you to go that far for using systems like this, it's serious enough for them to torture you for information.

>>12418
I don't disagree with you, but in practice, everything the state could do to a citizen for the retrieval of data they deem to be important for national security will be gotten this way. Of course, I don't delve much into the cryptonerd space because, while it is a lot of fun to think about how cool it would be for the NSA/FBI/CIA to be unable to break your system, chances are that the worst that's going to happen to it is that it gets stolen and sold for the hardware that carries it, and not for the actual information you have inside. The most valuable files I have are .rmvb files with anime from 2004. Now that was real fansubbing.

>>12428
So you seem to be saying. That we need a political movement to create deterrence against torture. Like fore example punishing torture with the death penalty. And a similar, albeit less severe, logic needs to be applied to political intimidation. We need to take the barbaric option from the table.

>There are plausible deniability tactics that you can use, but they're so niche
I think that unbreakable encryption is basically a requirement for privacy. However not all attacks against privacy are obvious and straight forward. The attempt to make effective privacy a legal liability, is the use of law-fare against privacy. While that is crazy illegal, and requires a political correction. It would be prudent to harden cryptographic privacy to withstand more than just technical deciphering attacks.

You say that making encryption invisible is not practical enough, idk. maybe that's a technical feature that could be enhanced to make it more practical. However if that's not possible are there other options ? For example can you make an encrypted vault that spits out decoy data if a coerced cipher key is used to decode it. My priority here is about rendering coercion moot. In this example with the decoy data, the utility would be to make it futile to beat a cypher-key out of people in order to render such barbarism impotent.

>>12429
>the retrieval of data they deem to be important for national security
Maybe that's also a lie. Maybe there is no such important data.

The threat is so expansive that it would require toppling the state to uproot completely.
