Glory to the PLA Navy! China has realized helicarrier technologies, the west trembles in fear!


Why would a flying aircraft carrier even need a runway? Just drop the aircraft from the bottom and they'll attain the velocity to fly.


>Why would a flying aircraft carrier
Something that big would have such a powerful exhaust that it becomes a wind-storm weapon as soon as it flies low over the ground, it wouldn't need any dedicated weapons or fighters.


What the fuck is that?

Does there exists distributed imageboard software in a sense that each user is a full node? Something like each node running a local server that user can access through browser with local servers synchronizing through DHT or something? All I found is some "overchan" but there is almost no info and as I understand this is not a full-node distributed system.
It has been on my mind for quite a long time - Anons need to seize the means of shitposts production.

No, because think about it. An imageboard has increasing post numbers, and how would that be incorporated between multiple sites? Who's going to keep track of what post number the whole system is on? And if different sites track them individually, then how would posts be copied between sites? if the post numbers overlapped then which would take precedence? and if you change all the post numbers it would break all the links as well, correcting that on one site is a bitch, imagine correcting it on a dozen.

Maybe if instead of a No.# it used some sort of hashing/consistent hashing, but then it wouldn't look the same. How would cross-site linking work? Maybe it would have to prefix a domain, like >>>>org.leftypol.1234 or something? but then that would totally change the way links look, not to mention involve an ungodly level of cross domain image loading on the hover thumbnails, etc.

plus there's the fact that most imageboards have extremely edgy content and wouldn't want to necessarily trust another site enough to be in a ring with them, seeour situation with getchan and how they turned out to be pedos and we were only in a webring with them, imagine if getchan and .org had been federated or something.

The technical aspects of making a federated or general distributed system would fundamentally alter the nature of what an imageboard actually is and how it even looks.

In my experience people generally underestimate the difficulty involved in making truly distributed systems with no central authority, just thinking about it for a moment will bring up all kinds of challenges/design decisions which no one has even begun to think of.

All these "muh federation" guys should literally be forced to read a book on distributed systems before spouting off about how its superior.

I've attached one here. Tannenbaums books is also good if you can get it


>No, because think about it. An imageboard has increasing post numbers, and how would that be incorporated between multiple sites? Who's going to keep track of what post number the whole system is on?
Each post could just have a random hash. Why does it need to be a number?


Another fucking thread about imageboard software and idiots trying to make another site that's exactly like your average IB except with one "new" gimmick (and zero users).


Cackling imagining post numbers being some 256-char alphanumeric string.


Because then it wouldn’t look the same as the Chans we’re all used to?

I am trying to degoogle as much as possible, but I have yet to find an alternative for Google Maps. I tried some alternatives, but they all are just inferior products with crappier destination times. I live in a huge metro area and—thanks to American-style urban "planning"—I need a good maps application to get anywhere. Can /leftypol/ help me out?

Also, general DeGoogle thread.


I use OpenStreetMap but I don't drive so idk


How do you use it then? OSM doesn't tell you how to use transit.

There is a widespread belief that people have "learning styles", like verbal, visual, auditory, etc., and they learn better when instructed in this "style". But the styles are ill-defined, self-reporting by students is unreliable and tests to determine them are contradictor. Moreover, experiments failed to find any benefit from instructional material tailored to specific learning styles, meaning that supposed "audiovisual learners" did not have any disadvantage from learning texts compared to students of the other "styles" and so on.


The entire debate is flawed IMHO, learning styles probably aren't about learning performance rather then about how much stress somebody experiences during learning. I want to see a long term study about how learning styles affect stress levels. People that get too much stress during learning tend to drop out. So the study should also compare the drop out rates of students with learning styles.

You have to pay attention that nasty cultural battles can ensue, where one subculture tries to cause another subculture somatic stress by changing institutional designs.

It is not flawed, the study addresses the claims of proponents of "learning styles" and not some random hypothesis that you have just made up on the spot.

By the way, competition and retention rates has always been terrible on MOOCs.


this post talks about stress
this post talks about educational results

talking past one another

what would be the ideal social network site???

Imageboards (ex: 4chan, *chan “alt chans”):

• Anonymous
• No registration
• OP requiring attachment forces content/memes to be produced
• Pruning catalog keeps server space needed to minimum
• Lack of upvote system reduces groupthink and disincentivizes non-originality
• Anonymity + siloing by board centered board identity over personality
• Linear reply structure that requires minimal interaction to read
• Effortposts that do happen are often phenomenal quality
• Attracts schizos, racists and “free speech” people who have been banned from other SM for good reason

Capitalist intelligence services will exist and try to work against us


capitalist intelligence services wont exist because capitalism wont exist


4chan but instead of boards you hashtag your posts like twitter


then everything will be an overboard that you can filter though


There are decentralized imageboards like that IIRC

>corporation threatens to deport man to China and report him for protesting the CCP because he developed a sheet music downloading program that they claim violates their copyrights

What's your take on this?



>What's your take on this?
He's a Chinese dude who hates the Chinese government, they don't want him deported back to China. They probably helped him to get a gig outside of China to get rid of him in the first place. The copyright trolls are crazy if they think they can commandeer the resources of the Chinese authorities to do their bidding, especially when he doesn't seem to have violated any laws.


Yet again, porky enforcing copyright on behalf of artfags.
Reminder that artfags (and other cuckmanities sorts) are the greediest rent-seekers to ever exist.


>Otherwise, I will have to transfer information about you to lawyers who will cooperate with github.com and Chinese government to physically find you and stop the illegal use of licensed content.

Believe me, faggot. My dad works at China.


>It is entirely reasonable to find the idea that some rando from 4chan actually went to some guy's house, brandishing an allegedly illegal weapon, with the intention of causing physical harm to somebody – regardless of the potential legal consequences – over a fork of an audio editing program. The premise is mind-bogglingly stupid on its face and clearly the product of a deranged, overactive imagination.

Dont higher temperatures allow for faster and more dense gases allowing for more powerful blasts?


Higher temps and low molecular weight gases are needed for higher velocities. Guns powered by the usual smokeless powders max out at ~6000 fps because their combustion makes higher molecular weight gases. Light gas guns used by NASA that use hydrogen as a working fluid reach 23,000 fps.


Low molecular weight per individual particle right? Since you would only need enough mass per particle to overcome the resistance of the object your trying to create a force on and thus too much mass wastes energy?


I think it has to do with the fact that low molecular weight means easily compressible and it has a high speed of sound.

Some breakthroughs have led me to finally and definitively abandon microshit's spyware.
I had been staying on wangblows for the audio software but had no idea Linux production had come so far.

My DAW [Renoise] has a fucking excellent native linux version that exceeds WIndows performance in some cases. Grabbing audio to feed into its sampler is easier than ever with youtube-dl and ffmpeg.
yabridge lets you convert Windows VSTs to run through Wine, the ones I've tried have worked seamlessly albeit with a little overhead.
Takes a tiny bit of elbow grease to get it optimized enough for serious use, but it's pretty simple once you get past initial setup and it even supports VST3.

Feels pretty good to be making music on a system I have so much control over, it's actually given me a lot of inspiration to work on new material.
Are you a composer or producer who runs Linux? What's your workflow/software?



I use Ardour, Vital, Helm, Geomkick, Surge, Stochas, sfizz, eq10q, and some other stuff like calf plugins.

I'm a total noob though so those might be terrible tool choices.

Does anyone know of any none fucked streaming services? Particularly ones that aren't shit on android? Youtube is trash for a whole host of reasons, especially on mobile. I'm not paying for spotify ever and doing anything on there just assaults you with an infinite amount of adds. Choose something — adds, rewind something — adds, don't skip a song in days — adds. I've always liked pandora and always thought it's a great idea but the execution is rather flawed. It seems to only play new or rarer stuff once in a blue moon. So does anyone know of any non-shit tier streaming?
