Any users of clojure around here? Apparently, it requires the fewest lines of code to write programs of any general-purpose language and has performance on par with Java. It utilizes the JVM and thus is multiplatform in the same manner as Java. It sounds very good on paper.

reddit has a json request thing. pretty convenient once you know. i was wondering how the fuck you scrape reddit or any other modern dynamic webpage bullshit.
i made something to scrape reddit porn videos so i can upload them to bitporno as an experiment. i do a json request for each subreddit and regex the particular video ids, check if its been downloaded before, then if not download them and log it. i added 30 subreddits. they were found on a redditlist website or something that shows nsfw reddits. i just went through the top ones and ctrl-f 'redgif' to see if they use it or not. some reddits dont, others are flooded with it, pretty weird. i ended up with some 12gb of 600 videos downloaded
i was wondering whether deliberate and accurately named videos matter. ill do a crude ab test with 100 vids i personally name, and then 100 vids that i try to scrape a name or maybe generate something. probably the time saved by auto naming and sheer bulk of uploads will more than make up for the decrease in individual views. but i will see

Haskell certainly is different from anything else I have used. The lack of loops is jarring, but the compiler magically makes recursion work somehow. Fewer lines of code are needed compared to using an imperative language. It's well suited to something like Project Euler. Some problems can be solved with a single line. Very little or no time is spent debugging (so far). I will have to try making something serious and see how painful of an experience it is.

Ended up using an existing d64 editor. I then spent several hours trying to figure out why my program wasn't loading a text file properly. Turns out, you have to edit the text in an editor designed specifically for C64 SEQ files. Using a standard editor in Windows causes byte-order information to be prepended to the file and zeros to be injected between letters and no amount of fiddling with vim or xxd seemed to remedy this.

>>57285I might be out of my depth here, but have you considered using something like a blockchain?
You can treat the database as a chain of consecutive changes (transactions) on an imageboard. An imageboard is just a public-private key pair that an admin/owner can generate and use to sign and verify his ban/delete transactions.
(1) User posted 34 chars on imageboard with public key #123871237
(2) User posted 12 chars on imageboard with public key #123871237
(3) User posted 54 chars on imageboard with public key #123871237
(4) Admin removed transaction (2) on imageboard with public key #123871237 (signed with private key of imageboard)
(5) Admin banned IP hash #1987231 on imageboard with public key #123871237 (signed with private key of imageboard)
(6) User posted 127 chars on imageboard with public key #123871237
Nodes can receive transactions and relay it to other nodes. If it's an ADD transaction, they check the ban list before accepting and relaying. If it's a REMOVE or BAN transaction, they verify the message with the imageboard public key (which serves as its ID as well) and then relay it to other nodes. Clients can ask a node to send transactions from the beginning or from a certain version number and then build the current version of the imageboard database by stacking transactions (initially takes a while, but then relatively fast).
The problem is that removed transactions aren't really removed, but are simply hidden (the client can still choose to see deleted posts by ignoring REMOVE trans. and dishonest nodes could still relay messages from banned users). I guess it doesn't really solve your problem, but I think it's somewhat in the right direction as a solution.

>>57317>engineering a decentralized IB with a single point of failure doesn't seem wiseYes, I know, wizard. The purpuse of that decentralization is a little specific, I want to make it possible to anyone to copy the entire imageboard and host it by himself or just help the server by hosting an instance but not having administrative rights over it. Decentralization is not the purpose, but a feature. So even if the imageboard goes down someone with a copy could host it somewhere, he could host a new version and be it's administrator inheriting all the content from the previsious IB.
I thought: if I added a "decentralization layer" upon Vichan, how that would be? I want to know what I can achieve with that goal. However, I am not programming on Vichan, instead I am making the software from scratch.
>>57318Yes, I considered using a blockchain, the problem I faced at first was that I do not knew how to determine the genuine chain out of each one, because anyone could remake the entire blockchain from scratch. Also, later I found that blockchains are slow and tend to be slower as the network grows, so I really don't know if I want to use a blockchain approach. What I am considering now is a database synchronization protocol approach.
Your solution is good and you gave me a direction, I think private-public key pair could solve the permissions problem, I just do not know how can I implement it. I need to learn more about asymmetric encryption.

I made a small web app for watching multiple porn videos at once in a grid layout. You can embed up to 25 videos at once on a single monitor. This is much more convenient than switching tabs or having to manually resize multiple windows into a grid. Currently supports a bunch of normie porn sites, but it's fairly trivial to add support for new ones if you know how to match the video URL with regex and transform it into an embed link. For some sites, you can't use the normal link but have to copy the embed link itself, because the normal link doesn't have a proper ID or key param, which is slightly more inconvenient. Can't think of a solution other than having to scrape the embed link from the page.

No.58090
>>58089Well in Unix it is quite simple, I am sure in Windows it is much the same thing, too, because they all use the same underlying sockets technology, afaik.
The server process is run as what we call a daemon, that is a process that is detached from a terminal (so it's just the process with no front-end like a command line, gui, or anything), it opens a new socket, which is the standard implementation of all network operations. It is really, just like pipes and other IPC mechanisms, an object (ie. datastructure) in kernel space. Sockets are just that: a tool for IPC which is persistent, and provides a two-way communication channel, possibly reading and writing to a network device (it too a datastructure in the kernel).
Back to the server software, in order to service several requests concurrently, whenever it receives a request, it forks a child process in order to service that request, so it can keep on listening and servicing other requests. The functionality here is just as with any other process, the kernel has some chunk of data available for the program to read as input, process it and return some output. Sometimes the connection is persistent, sometimes it is readily dropped (I'm not sure how http does this, it is in principle a tcp connection, which would have to be explicitly terminated by either end, but it also can just serve a page and terminate, I guess implementations decide how long to keep a process listening for aditional requests, which is often the case (consider loading a page with several files, and having the user navigate the site.))
As for the rest of the process, it all happens on the network logic of the kernel, which encapsulates the details so as to run more or less as I just described. The server does not need to know about how the kernel multiplexes the network device into ports, or how tcp manages to keep data integrity, etc.

If you try to load more than program into memory directly from BASIC, programs clobber each other. They don't load neatly into the memory locations you would expect them to load into.You're thinking too hard about this. Remember that the basic load function is itself just an assembly routine, which is built on top of kernel routines from the c64 rom. The basic load function likely maintains its own pointer to where it thinks free memory is, like how malloc/sbrk does, which is where the ambiguity is being introduced. You can read the load disassembly here
https://www.pagetable.com/c64ref/c64disasm/How can you break out of this? If the basic load function calls your own load routine then you can do what you want. Alternatively, you could use the kernel routines like basic does. If you can get bytes into memory you don't need to reboot the machine, they can be immediately executed. Now, because you're dealing with a machine with expanded memory there's an additional annoyance, but all that means is you must flip some bits in the memory controller to access the page from banked memory you want. As far as the CPU is concerned there's only one address space limited by the physical width of the address bus.

>>58112I'm realizing that the problem isn't the LOAD routine, it's the fact that BASIC frees memory the moment it thinks it is no longer needed such as when you modify the program stored at Start Of BASIC. To get a ml program to run at all from BASIC, the bare minimum requirement is to assemble a header of bytes at *=$801 which translates to
10 SYS 4096 (or wherever the ml program actually starts)
At this point, you can actually start it with a RUN or a SYS call. The moment you try to modify the one-line BASIC program to something like
10 FOR I=0 TO 10
20 SYS 4096
30 NEXT I
40 END
the routine stored at 4096 disappears. I think the magic may lie in moving various pointers around and/or changing the header to contain a different line number.
None of this really matters unless I want to write BASIC programs that call machine language routines. The C64 Programmer's Reference Guide might explain it.
No.58141
Hmm. Without the BASIC header, LOAD puts an assembly language program at $801 regardless of whether or not it belongs there. With the header, the actual assembly code gets put in the correct location. However, once you make any modifications to the BASIC program, the machine code gets displaced. BASIC thinks everything between $801 and the end of the machine language is one big BASIC program. Moving the top-of-memory pointer does nothing to prevent code from getting moved.
It does seem like writing a short assembly program to load the real code into memory is necessary, possibly in conjunction with using the top-of-memory pointer to protect the code from being eaten by BASIC.
No.58144
Learned many things about BASIC today such as how to create and delete files and write data to SEQ files. Made a short script that creates a table of pre-computed random bytes that can be included into an assembly program and a sprite editor. The table generator could be modified to generate tables of trig functions for instance. The sprite editor works by editing DATA statements in a BASIC listing. A nested FOR loop can be incredibly slow in a scripted language running on a CPU from the mid-seventies. I could maybe optimize by making the inner loop machine code. Going to make a screensaver by making differently-colored circles bounce around the screen randomly. Maybe I will try sprite multiplexing. Or try loading the sprite data from disk in machine language instead of just building it into the code.

Even with accurate disk emulation enabled. I'm using the c64 "maxi" btw which is pretty neat and generally works as intended but not the C compilers. Forth, on the other hand, works pretty well. The binaries that it builds are huge because it builds the compiler, forth kernel, assembler, text editor and various libraries into the binary by default. I will have to figure out how to trim things down. Durex forth is, according to its creator "50 times faster than BASIC" which puts it on the same level as C (about half as fast as assembly).

I might be able to eliminate a few steps by using the RAM Expansion unit and a single disk for souce/object/binary but I think it will fuck it up somehow. All this for a program that in the end will run at half the speed of an assembly program or slower because the computer doesn't have enough memory to optimize code.
Forth is interesting but also kind of stupid. A function that evaluates the expression "9a^2 - ba" is written "over 9 * swap - *" and it is essentially a sequence of operations on a stack. I can't figure out how to make my programs launch automatically which means that they have to be invoked through the interpreter which means I can't strip the interpreter out of the binary which means that my program has a debug console built into it that can't be removed.

Welp. Turns out you can load machine language routines into their correct memory locations with LOAD "<program name>",8,1 as opposed to LOAD "<program name>",8. If you omit the 1, the program always begins at start of BASIC and ends at the end of the range it was assembled into.

You can't bypass google captcha unless you pay a team of pajeets to solve them by hand, as far as I'm aware. Even then, it's tricky.
On old style captchas that were just typing words, you could try to clean it up, then put it through OCR, or more reliably, just save the image, then have a hivemind of people solve them for 1-2 cents each. If two or more pajeets give the same answer, you can be 99% sure it's correct.
But google captchas are more sophisticated, they make you select certain images and also require you to act like a real user, so any sudden, robotic movements of the mouse, doing things too fast or too slow, or just not having a real browser signature, immediately flags your IP. Also, if you use known VPN proxies or TOR, it makes their captchas more difficult.

Isn't it mostly problem solving? If you want to build a motor you have to use copper wires and magnets (or metal) whatever needs to be used to make the thing work. I suppose you are plagiarizing Edison or Tesla. I get it when it's blatantly stealing when it could've been done a different way, but if you're using the same programming language how do you not use the same stuff to make a similar or same product?

>>60288Prolly about the best you could do would be to lean heavily on multithreaded libraries. I'm guessing you also don't have the mind nor desire for math libraries. But if you think more in terms of scripting then it could be anything from sorting a lot of data to transcoding a movie, and something like python has such gigantic 3rd party support that you'd have like a million different libraries to use for computationally-intensive bits.
Another sort of thing that's inherently multithreaded any kind of a website sort of thing where you're normally expecting multiple simultaneous users. If you know what a for loop is, then you also know that a lot of times you could as easily be doing the looping in parallel rather than one by one, and some languages, like Java 8 for instance, have come a ways in making that easier to do with thread pools and whatnot so that you don't have to muck about with all the details of thread management as much.
And of course there's always hadoop for really large scale stuff, but reorganizing an algorithm in terms of one or more mapreduce jobs can really take some thinking cap time, not to mention the extra effort needed to set up a hadoop installation. But sort of the babby step toward industrial strength things like that would be simply to recognize that a lot of languages feature a "map" function, whether that's built in or just a library, and if you start thinking about how to organize computational problems around using that then you're a good step closer to thinking about how to break up a computationally intensive operation in a way that lends itself to easy multithreading.

https://pastebin.com/raw/zJ0gnpXaYou can look at MAME source for proper names, but Github only lists the first 1k
When you start a game inside MAME it lists the driver being used so you can get it here too.
https://github.com/mamedev/mame/tree/master/src/mame/driversIt's not perfect. The pacman driver pulls a bunch of other games that aren't Namco's, for instance.
You can also use it to create sets for other emulators. I'm a Sega fan, and MAME is terrible for emulating model3 and naomi. The emulator Supermodel expects games to be unmerged and zip compressed, which is beyond the scope of this script, but you can pull the files and rebuild with a ROM manager.

Next one is the Ui, how do you talk to your server, how do you display the state the REST API has given to you, how do you do CRUD operations to alter the state of that data…

[2] the time when the 'data' event is triggered, This is not strictly under your control. This will happen when nodejs feels like it. This is not identical to [1].
In those instances when you see the unmodified 'data' variable printed by console.log, what happened was that console.log ran between [1] and [2]. At that point the 'data' variable was not yet modified because your callback function was not yet executed, because the 'data' event had not yet triggered. If you wish to consistently see the modified 'data' variable printed by console.log, you must ensure that console.log runs after [2].

https://pastebin.com/jUBzn7vCvery random but i wrote a bot for roblox tower defense simulator last night. it is a game i occasionally play with my sister's kids when i watch them over the weekends
the problems :
- you spawn into server in 1 of 8 random spots. i pixel search to orient the bot and then do a preprogrammed movement to reach a game lobby
- need to figure out what map you are playing on. i capture the map title region and imagemagick compare it to other map title images to figure what map is loading
- every map is different with different valid/invalid tower placements. for this i made an .ini with [sections] of each map containing valid tx and ty tower coordinates to place the tower on screen. so once map is figured out you get those coordinates.
then it is a matter of just continuing to upgrade the single tower, skip levels when prompted, and waiting for defeat since it is only a single tower. it earns 1000 coins per hour which is pretty good. so now i don't have to grind this game anymore to not disappoint the kiddos when i have shit towers. it wouldn't be too hard to add more valid tower placements but the coin/hour ratio is fine there's no reason to waste any more time on this

is there a way using notepad++ to automatically correct specific words as i misspell them?
for example GameOBject > GameObject
i type it this way almost every time and my brain doesn't seem capable of telling my left thumb to release shift after typing O. the spellcheck plugin doesn't automatically correct. autocomplete is also weird i dont like tools that try to finish what im typing or show popups with text. that's the whole point im using notepad++ and not a fancy ide.

>>61334I haven't used npp before but apparently it has a plugin system (
https://npp-user-manual.org/docs/plugins/#how-to-develop-a-plugin). Here's how I'd do it incrementally:
1. download example plugin, build and run it (probably hardest part)
2. modify plugin with an array like { "abc", "def", "ghi" }, insert a string from the array when you press a key
3. fuzzy match between strings in the array and text under cursor, insert closest match
4. populate array from ctags, which runs whenever you save a file
It may sound like too much effort to implement your own autocorrect, but once you've done it you can extend it to do whatever you want. You could also make npp jump to definitions from the ctags file, or open your browser to search text under the cursor, as examples.

twitter denied me a developer account years ago because "automatically downloading tons of porn" wasnt a good enough reason in their opinion. turns out you can just use other twitter front ends, and while i would like json output, at least these websites aren't single-page javascript turds like twitter. try to look at the html of twitter. it's not even human readable. Reactjs is fucking gay. it's also these javascript websites that have weirdly autogenerated obfuscated elements and names that make adblocking difficult sometimes

>>61515>try to look at the html of twitter. it's not even human readable. Reactjs is fucking gay. it's also these javascript websites that have weirdly autogenerated obfuscated elements and namesIt's really bad. If you scroll down twitter the next block of posts is returned as a (deeply nested and garbled) json response based on scrollbar position, then that response is appended to the dom with javascript. It's designed to be slow and hard to scrape. Thankfully, like you say, people have made better public apis.
I've been porting my image/booru viewer from lisp to c. The initial port used sdl, but it's 2slow4me so I'm using plain opengl now. The first problem I encountered was managing the limited number of texture units on the gpu, which sdl does for you, because there are more image thumbnails than texture units. In the screenshot the 512:512 texture is uninitialized memory, then the unordered thumbnails are stamped in the texture using shelf next fit. Tomoko on the right is drawn using the normalized uv coordinates returned from the function.
Also, I like the opengl 1 api better than the newer versions. You should be able to open a port and stream instructions to the gpu, or do it the ogl 1 way. The newer stuff overcomplicates things. Different stages of the modern pipeline could be exposed as registers instead of the inout parameters in shaders for example, it would be simpler and faster.
No.61602
>>61556Added text stuff and asynchronous autocomplete with caching.
The main problem I had was my string pool used realloc to resize the pool, but I forgot you may lose anything that was pointing into the previous allocation, so my strings would get overwritten with server responses, and the async stuff would write into freed memory and crash the program. The fix was to expand the pool by putting new allocations in a list, so they don't change over the lifetime of the program.
No.61631
>>61602Now we can browse pages and download stuff.
There's not much new functionality. The program just extracts the necessary fields from each post (if they exist), compares them to a cache of posts, and if we don't have it download/decode the thumbnail, adding it to the texture atlas. The draw list just points into the cache and is assembled on the fly. Most of the speed improvement in this area is from using persistent connections and decoding jpegs in parallel, but we're ultimately limited by the speed of the server (200-300ms) unless the cache is hit.
The program is basically finished, but there are still lots of refinements to make:
>be able to navigate by rows (the program just blindly draws until it reaches the edge of the window, so it has no idea what a row is)>center thumbnails vertically>rendering is incredibly slow, we spend 3ms making 352 opengl calls just to draw a page, it can be sped up by throwing all vertices/uvs in an array>maybe prefetch the next page to make browsing faster>add a download queue, instead of blocking the program like a retard every time `d' is pressedAnyway, I'm really happy now it's usable, this is much nicer to use than my first attempt.

>it's used by visual studio. do i really need to use that collossal bloatware garbage?you don't need to use visual studio's compiler and linker (cl.exe), you can use whichever c compiler you want to build imagemagick. on wintoddler 10 this will likely be mingw or clang
the instructions for what you want to do are literally in your link, it's just a remarkably badly written wrapper library (i lost my patience when i saw xml in comments), so you'll have to invest some time into examining how dlemstra builds imagemagick and creates a c# binding for it to integrate it into unity. the main difference will be instead of using whatever datatype dlemstra defines for wrapping imagemagick's representation of images you will use unibabby textures instead

>for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.png" -filter_complex "overlay" -codec:a copy "output/%%a"
this works but the image just completely replaces the video. i ask for a duration for the overlay, as well as a transparency amount for the overlaid image
>for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.png" -filter_complex "[1]format=rgba,colorchannelmixer=aa=0.5[trans];[0][trans]overlay=duration=5" -codec:a copy "output/%%a"
this seems like it should work but it seems windows doesn't have this duration option so i ask it for something else
>for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.png" -filter_complex "[1]format=rgba,colorchannelmixer=aa=0.5[trans];[0][trans]overlay=enable='between(t,0,5)'[out]" -map "[out]" -codec:a copy "output/%%a"
this works, each video begins with the respective overlaid image, and the transparency/duration is adjustable. however the audio was discarded

i will probably just desaturate it until it matches or something, i don't know what else to do. it seems like such a hack but i can't figure out how to produce the dull variant via commandline, because all the other editors and stuff produce the exact same dull image, which means they aren't just arbitrarily desaturating, they are using some method. i thought it was just a result of ignoring the color profile but imagemagick doesn't seem capable of converting to the dull variant. i've tried all 5 profile intents as well

i figured out the image is utilizing adobe prophoto rgb colorspace, but windows explorer is not color managed and interprets this as plain rgb or something and it is desturated. while incorrect, i strongly prefer the desaturated version that windows and other programs show, instead of the overly vibrant and saturated correct version that color managed photo viewing apps show me
still haven't been able to figure out how to convert from this color space, but i did figure out i can desaturate, lower blue channel, raise red channel, and then lower contrast to achieve something similar
if i change my gpu or display, it will affect everything, but only these images are bad. id rather just find a way to fix them before changing how everything displays

>>65596can’t you just tag the images as SRGB so that color managed renderers will emulate the "wrong" behaviour?
No.65606
>>65601i have tried all sorts of things, but no i can't figure out how to simply render it as rgb or use the wrong colorspace, which i imagine non color managed stuff like windows is doing. at this point im considering finding very very old versions of image libraries or something with commandline to see if it can produce the effect
i want this incorrectly desaturated version because it paradoxically shows more detail, at least for my monitor. the saturated one has horrible color levels and looks like a mess

ffmpeg.exe -i video.mkv -ss 110 -crf 30 -preset veryfast -vf subtitles=video.mkv:si=0 video.mp4
i had to hard encode subs to make anime playable on my old phone, this is what i used
ss 110 skips the first 110 seconds, skipping the intros
crf 30 is really low quality but significantly reduces filesize
preset veryfast just speeds up encoding
-vf subtitles=video.mkv:si=0 is a filter to hard encode the subtitles from video.mkv, using the 1st(0) subtitle index (english) - you look at streams by via ffprobe
the problem i had was trying to map select the video, audio, subtitle streams while also hard encoding them with a filter, in one pass. i still dont know how to do this, but this seems to select the right audio and video streams without specifying it, leaving only the subtitle stream necessary to specfy, which lets you filter it since no mapping is done. it is simple but i spent an hour figuring it out. i really wish someone posted this to the stack overflow thing regarding converting mkv to mp4 and retaining subs

what am i even supposed to do with programming
i learned a language (atleast, the fundamentals of how it works) and thought it was gonna be a great hobby for an autist like me and i could put all of my time into it, but i half assed what i finally wanted to do with it in the first place and now i cant even get the motivation to even do any more of it. 90% of the time youre just staring at documentation and googling stuff and i cant be bothered when i dont even know what i wanna do with it anymore.

the problem isnt learning to code, since i know how to read and write code to an extent now,the problem is,how do i inspire myself to actually create something and how do i create something that would be worth creating?
No.68403
>>68400That's part of the problem I face
The uh standard answers is you
-solve simple everyday problems that arise in your computer use
-solve standard challenges like idk advent of code, that kind of shit
-do something for your own amusement, like a game or shaders
-learn a lot about languages and never actually write programs just argue over their design over the internet

>>68400I have been stuck at that point for years, mostly because the things i really wish i could make are only suitable for highly skilled developers. I feel like there is a gulf between what i can make and what i could be passionate about making. I think it is the same for artists that struggle to enjoy making art while their skills are still developing. Perhaps the only solution is to push through it and make things for the sake of learning until inspiration strikes and you think of something you can do and want to do
