Here's a pretty shitty demo of the webcam so far. I haven't bothered with YUV to RGB and with frame rates (yet).

It pauses on the first frame because that's the first ID in the linked list. This ID's air time is in the future. Since it can't scroll back to a previous frame, it keeps that one (only newer than current timestamp because it is a test).

Rust is a shit replacement for Java. Everybody seems to compare Rust, Go and D together like they're all the same shit, made for the same shit, designed to be used in the same ways. That's crap.

Of the three, D is the most obvious replacement for Java - there's a garbage collector, it still has objects (but is less strict about them), and it still uses C-like syntax. The skills picked up from Java should be more or less transferable to D, while shedding the shittiest parts of Java. People who are able to pick up Java should be equally capable of picking up D.

I want an algorithm that finds the smallest amount of pixel displacements and or pixel shade changes between two images given some maximum radius for moving pixels about.

But I don't know a name for this. Except possibly Levenshtein distance. Which doesn't quite seem appropriate. I guess it could work if I just chunk the image into pieces and match between chunks.

So let's say I want to develop a bot for a game using only the screen view (i.e. checking the color patterns of the monsters for the current view) and not read memory and relative to my own character. Assume I can already detect the monsters and my character.

what programming techniques and/or data structures are there for this? Do I have a "handmade" outline of the map dimensions which then includes the monsters/characters locations updated every half-second/whatever and then move my character relative to the updated difference to the target monster?

Using python 3.4 to edit SVG images and save as PNG. I tried out the py module called "cairosvg".

However, it seems there's a shit ton of dependencies, including installing Cairo graphics backend. I have read this guide and so far it's terrible as hell to go through this. I installed MS visual studio and converted these vcproj files to solution files. But trying to build the solution file just leads to more error bullshit.

https://www.cairographics.org/end_to_end_build_for_win32/

I'm thinking about just going with Inkscape and command line tools instead to convert SVG to PNG. Is there an even simpler way than both of this shit though?

>>58582998
in what way? literally every single line there is obvious even to a beginner

>>58582849
optical flow? dense/improved trajectories? HoG? HoF? iHoG?

>>58583170
If you're trying to do batch conversion, ImageMagick is probably the best way - it's even available as a package in Chocolatey, if that's your jam. ImageMagick is as simple as

convert in.svg out.png

Seems sort of like an obvious feature, but I just added the ability to open entire directories in my image viewer, Ivy. Wasn't too difficult to implement, just never got around to actually doing it.

>>58583234
>trying to do batch conversion

Not exactly. I edit specific SVG files first using user inputs and whatnot in the python interface.

Then, after that, if user wants to "save" the svg as a hard picture, I want a simple button in the interface that says "save". I don't want the user to have to open up another program and have to load all this backend dependency bullshit.

>>58582885

Does anyone know if pic related teaches you OOP with Common Lisp?

How did you go from small projects used to learn the language (hello world to implementing data structures) to actually making software.
I feel like even though I know a language, I'm missing every other tool needed to actually write something useful

>>58583291
Have these people even once thought "maybe it doesn't need to be object oriented"?

>>58583291
No, it's about embedded C.

>>58583291
[spoiler] probably, here's your (You) [/spoiler]

>>58583276
you can edit the svg, save as svg to a temp directory (or memory and use named pipes..) then use your languages os execute library to run imagemagik to do the actual conversions

calling out to third party processes for image/video manipulation is pretty common (from languages like python, unless you use a cpython wrapper for said libraries..) when you don't want to have to deal with messy / complex (to build and use) libraries like: libavcodec / libavformat

>>58583276
In that case, there's probably not a very clean way to get around the Cairo dependencies. If you really want to have the ability to modify images you're going to have to just live with the fact that there's no built-in way to do it in Python. There is a Python interface, librsvg-python, that will probably do a lot of the heavy lifting, but it depends on librsvg, which depends on Cairo.

>>58583305
I have never felt that feel.

>>58583309
but CLOS is literally the only reason to use Common Lisp over, say, a Scheme variant

>>58583013

The problem is that Haskell syntax is incredibly unintuitive.

>>58583305
There was never a moment where it just happened for me. It was all incrementally larger programs or small shit to get the hang of more complex concepts. It's more or less the natural progression of programming courses in college. It can be daunting to try and flex your programming muscles but have no idea what you're actually capable of doing, but so long as you keep doing something even slightly more difficult you'll eventually start making large and complex programs that might even be useful to other people.

>>58583325
Scheme has access to CLOS as well though (via TinyCLOS)

>>58583339
No it isn't, it's incredibly intuitive.
What part of it would be unintuitive, to somebody who knew regular lambda calculus?

>>58583313
>calling out to third party processes for image/video manipulation is pretty common

Still requires the user to install yet another program. But at least it would be a clean an easy way of doing it, instead of Cairo build bullshit. >>58583316 . I've never felt so much hatred for dependencies in my life until today.

Welcome to Windows programming. I cannot fathom how people managed to program anything on such a shitty platform.

>>58583380
i don't have an education and it's still pretty intuitive.

>>58583382
the way CLOS does OOP is vastly different from bog-standard Java or C++. If you have any experience with AOP (aspect-oriented programming) or MOP (metaobject protocols) you'll breeze thru it.

>>58583214
Not quite what I wanted. I'll look into that too though.
I want something more basic. No attempt at edge detection or anything. Simply morphing one image into another on a per pixel or group of pixel basis.

explain it to me as if i were 5 and can on reference a kindergarten classroom, playground, home, bus:

how does one go about creating an online database (firebase) where the app (mobile/web) can upload the data from a form along with a few photos and all the classify as ONE upload or ONE submission but each item could later be viewed in the whole or independently.
(maybe there's a word for this, idk)

>>58583406
you just bundle convert.exe with your program.

>>58583490
Just because a language has functions and lambda closures does not mean that it has to use a syntactic style similar to lambda calculus. A number of languages adopted a C-like style of syntax because it's pretty goddamn legible. Others adopted their own syntax in an attempt to read more like English, to varying degrees of success.

Use mechanize in python 2.7 and use:
br = mechanize.Browser()
br.select_form(nr=0)
If the login is the first field that you can fill with something it will be nr=0, otherwise increment with 1 until you get the right one. Then you will have a handle to the form and can fill it and submit with:
br.submit()

trying to troubleshoot an issue with git, i'm hoping someone can point me in the right direction

On my desktop, running "git diff" just outputs the results to stdout. This is how I would expect it to work. On an alpine linux docker image that I am developing on, however, "git diff" seems to open the results in some sort of editor that I don't recognise. This is causing me some problems. Anyone know how I might be able to change this behaviour?

>>58585498
Does using /usr/bin/git do something different? What's the output of `which git`?

>>58585498
try git diff --no-ext-diff
if that fixes it, check the gitconfig for diff external / diff tool

>>58585521
The output of which is /usr/bin/git. Explicitly using /usr/bin/git does not change anything.

>>58585530
--no-ext-diff doesn't change anything unfortunately.

I can't figure out what this diff viewer thing is. It looks a little like vi, with the column of tildes, but it doesn't let me input any commands as far as I can tell

>>58585540
Scratch that. If I hit S, it prompts for Log File. If I hit M, it prompts for Mark. Does that sound familiar to anyone?

>>58585540
>I can't figure out what this diff viewer thing is.
It's 'less', if I'm not mistaken.

>>58585540
what does these return?
>git config --global diff.external
or
>git config --global diff.tool

>>58585540
It's probably vimdiff. Try git config --set difftool.prompt true.

>>58585559
Actually, I just tested a git diff on my computer.
It is indeed less.
However, you can force the pager it uses with an environment variable.

PAGER=more git diff

or set it to nothing to just dump it to stdout

PAGER= git diff

You would set this in your .bashrc if you wanted to have this behaviour all of the time.

>>58585559
You're right, it is less. Why is git diff opening less?

>>58585570
Neither of those return anything

>>58585571
I set that but it hasn't changed anything


Thanks for the help so far guys

>>58585593
>Why is git diff opening less?
Because it's what most users would want. less is a very nice pager.
People usually don't wants dozens, or even hundreds of lines dumped to their terminal.

>>58585609
and some terminals don't support scrollback buffers...

>>58585592
>>58585609

Brilliant, thanks guys. Setting that variable didn't help, but you led me to find git --no-pager which I've now set as an alias for git. That will do fine for my purposes.

Probably wouldn't have figured that out without your help. Thanks again

>>58585592
Also, I should note that PAGER is a "standard" environment variable, so setting it will have an effect on other programs.
'man', would be such an example.
If you just want to affect git, you would set and alias or use git config.

>>58585643
>Setting that variable didn't help
Either you didn't do it properly, or maybe you're on windows or something and git's behaviour is different on that.
You got it working though, so I guess it's not important.

not him, but how is javascript not a real language?
what properties determine if its real or imaginary? (fake?)

a type system? well, look at C's type system and how its barely typed. then look at Elm or PureScript and how its using System F<: lambda calculus to do type deduction.

interpreted vs compiled? thats an implementation characteristics. there's nothing stopping you (or anyone) from writing a js->elf/coff compiler. and vice versa of making a language run in an interpreter.

What?
Just because there are implicit int/float conversions and void pointer conversions, it doesn't mean that C is "barely typed", whatever that means. In the places where it actually matters (structs and pointers), the C type system does the job.
