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 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.

👍 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,

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.

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.

A topic that was almost completely neglected in Marxist circles , was the privatization of online reputation systems. Most of the big tech corpo platforms just deploy some kind of algorithms or payed reputation badges. Technically this isn't a new phenomena the first privatized reputation system probably was something like banking credit-scores.

I think that maybe the toxic elements of social media like cancel-ism might have been the result of those privatized reputation systems.

I'm wondering why there don't seem to be any prominent non-commercial community p2p driven scoring systems ?

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.

Are people using generative AI backwards ?

For example, lots of people AI-generate text and try to publish it as paper-books on Amazon, which amusingly clogs up Amazon's pipes. In essence they use new AI computer technology to make more content, faster, for an old paper interface technology.

What people could be doing instead is make the content for a book them selves and then train a limited AI on that. Resulting in "ai-books" that you can talk to, ask it questions and what not. Which would make AI the interface for the content instead of the author.

A human book author combines 2 types of inputs.
1. all the books the author read.
2 all the experiences outside the textual book-world, aka the "real world".

AI only gets the first type of input, because AI has no experiences in the "real world".

If AI replaces all human authors, there won't be any new experiential inputs. Shit will stall for a long time until AI get advanced and corporal enough to have it's own experiences. It would make vast quantities of new works from a stagnant source.

The AI-interface-book that you can ask direct questions, is obviously most useful for text-books that you query for knowledge. But if would also offer new ways of story telling for fiction, like letting you talk directly to various characters.

So apparently Palemoon became the first browser to officially implemented JPEG XL a week ago. At the same time, Google just dropped it from Chromium despite supporting it behind a flag for months. What the hell is going on here? Is Google that desperate to push their video-codecs-as-image-formats that they're willing to sabotage a massive step forward for the web? JPEG XL is capable of replacing both original JPEG, PNG, and animated GIF/PNG all at once with a single file type that produces superior file sizes for all three categories of use cases. Neither WebP, HEIC, nor AVIF were ever able to make such a broad, sweeping improvement because they are geared more towards features important to video encoding than still images or lossless animation.

It seems like every few weeks these days I find something new to get mad about in the world of web development.

On the contrary, they recommend Webbrowser aka WereFox.
And the Palemoon website blocks Tor users so fuck them.

FYI you can use Tor Browser without tor:
network.proxy.type 0
network.proxy.socks_remote_dns false
extensions.torlauncher.start_tor false
TOR_SKIP_LAUNCH=1 TOR_TRANSPROXY=1 ./start-tor...

You're welcome.

For some reason those settings change back to default when I restart the browser, it's seriously about fucking time that someone who isn't evil or an idiot creates a web browser.
Or to ditch the concept entirely and create usable P2P software for content and thought sharing.

Google wants to put DRM into the web, and lock everything into their chrome browser and make privacy violations even worse.

I think this is part of bigG's war on addblocking and of course they're a monopoly that wants to be the entire web. But there is more, web-advertising has been sort of dying a slow death for some time now. Not because of addblock but for other reasons. Neo-liberalism/capitalism is making people poor and that's shrinking the economic pie in general. If people see adds they ignore them more often. And there is of course the scheme for generating fake views for add-farming.

The drm googl wants to insert into the web is super terrible, if they can push this through it will destroy the web. There is no hyperbole here, the web will become like one of those locked down alternate versions of the internet from the 80s that failed so hard that barely anybody remembers that they even existed. It's possible that EU regulations against anti-competitive behavior, and monopoly-busting in the US could cock-block google, but it would be better to fight tooth and nail to kill this one in the crib, before it gets anywhere near that point. And then outlaw DRM for violating personal property (if you can't fully control your gadgets you've been expropriated)

If this monstrosity were to happen, it would probably take over 10 years to polish one of those decentralized peer to peer alternative web-protocols to the point where we get something like an open web back.

The other thing to consider is that some middle class NPC who takes out a $100,000 loan to buy a Tesla is not going to risk his warranty to save $1000 on a DRM locked feature.

Not really, i think DRM is shit because on a technical level it's basically the same as malware, that fucks up your system. I know that it's intellectual dishonest and pure opportunism to link DRM to Scientology's cringe, but this is how DRM shills argue, and this presents an opportunity to throw some crazy shit back at them.

>if the firmware is burned into ROM or cryptographically verified before execution then power glitching will not open up a permanent solution to anything.

A special chip that works like a walled castle, which will definitely keep out the undesirables is a really old sales pitch, including all the invulnerability claims of this time we build the wall high enough. Don't count on it. In the long run people will probably move towards re-chipping with open chips that aren't locked down.

>And if the globalist billionaire class get their way then all cars will be $100,000 EVs that few people can afford to drive

Well if most people can't afford cars, we'll only need bus-lanes and bicycle lanes.

So apparently Apple gave in and let right to repair legislation go through, after fighting against it tooth and nail for at least a decade, after engineering lots of anti-repair "features" like proprietary screws, and digital spare-part incompatibility mechanisms for controllers, buttons and sensors.

Now many people think something is up, and that they might have hatched a new scheme.

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.

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.

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.

Veritasium made a video about "airships"
https://farside.link/invidious/watch?v=ZjBgEkbnX2I

And it appears that he fell for the old airship-con. The con works by pretending that these things are analogues to ships floating on the ocean. But they aren't like ships at all. Ships sit between the boundary layer of two media, usually air and water. They're stuck in the vertical axis and can only move in 2 dimensions. That allows for a relatively simple control scheme and much optimization.

Air"ships" on the other hand should really be called Air-subs, because they behave more like submarines that move in at least 3 dimensions and usually only touch a single medium. They need a much more elaborate control scheme that leaves a lot less room for optimization. Why relatively intelligent people tend to get fooled by this is somewhat a mystery, even if you don't understand any of the physics. So called Air"ships" don't even look like ships, they look more like Submarines, and you don't need to fill ships with a special gas or liquid to make them float.

Submarines only have a few niche applications, like military, deep ocean research and suicide-cans for rich adventure tourists. Similarly Air-subs will also only have niche applications.

Veritasium says that there is potential for mass-cargo-transportation. But there isn't, all viable mass-cargo transportation methods have one thing in common, The ratio of cargo-to-vehicle skews very far towards cargo. Airsubs will never be able to do that. You'll always need a lot of Airsub for relatively little cargo. At least in earths relatively thin atmosphere. Maybe on Venus with it's dense atmosphere this would be viable, and Airsubs will have their day once we begin colonizing the upper atmosphere of Venus with sky-cities.

The reason why the idea of Airsubs is still so magical is because they promise "Free lift". Filling up lots of gasbags with hydrogen or helium probably isn't the way to get it. But there might be another way, that is derived from hot-air blimps. Hot-air-balloons and blimps use large fuel burners to heat up air inside a bag. Hot Air is lighter than cold air hence you get lift. Every airplane has a source of free heat, the waste heat from the propulsion engine. It might be possible to blend Air-planes and blimps in order to recover waste-heat and use it for free lift.Post too long. Click here to view the full text.
