I only do big projects (i.e. take 1+ years to complete). This way I never run out of things to do, as I have more than enough time to figure out a new project. Of course the initial project might be tricky, but after that it is easy.

I could solve yet another project euler problem.
Or learn yet another language.
Or write yet another sorting algorithm/whatever generic compsci practice problem.

But those things don't give me the same enjoyment anymore.
I want to try making something bigger, something that's actually useful... a complete product, in a sense.

My problem is just that I can't think of anything that would be fun or useful enough that I would stick it through and see the project to its end. Everything is either too big in scope, dead boring or has been done before a million times.

I am using the bash on windows thing. Am I a programmer yet?

hi, i need a little help reversing this proprietary thumbnail
already tried emailing the devs, no response
found on some forums that what i'm looking at is a base64 encoded png stream
here's an example http://pastebin.com/GpsLrG9k
the final image should have a 16:9 ratio, unsure of the size..

what i've done so far: figured out that the charset used is [a-z,A-Z,0-9] and [.+] but standard base64 encoding uses + and / instead of + and .
replacing .'s with /'s didn't work, replacing +'s with /'s and .'s with +'s didn't work. by didn't work i mean i decode the base64 as binary and write it to a png file, but the file doesn't open at all in an image viewer

do i need to fucking try every permutation of possible mappings of the current char set to the real base64 one? how will i test to see if i get a valid png out of it?
using python.. here's my code so far

import base64 
import xml.etree.ElementTree as ET

xmlfile = './test_thumb.xml'

tree = ET.parse(xmlfile)
root = tree.getroot()

b64 = root[1][0].get('data')
b64 = b64.replace('.','/')

# padding (unnecessary)
# b64 = b64 + "=" * ((4 - len(b64) % 4) % 4)

bb64 = bytes(b64, 'utf-8')
png_recovered = base64.b64decode(bb64)

f = open("./test.png", "wb")
f.write(png_recovered)
f.close()

any help is appreciated

Well in any case you are missing the header.
Base64 files start off like this: data:image/png;base64,

But you're right in that it's not normal base64. It could be some other standard encoding I'm not familiar with, but if you're unlucky they've rolled their own in which case you need to reverse the binary that encoded them.

so why aren't modern operating systems made with persistent memory by default

i.e.

- all operations automatically persist to permanent storage, and memory is only used as cache

Qt atm. wxWidget is a valid option, though.

My ratings for multi-platform solution:

Qt: the best, beats hands-down even most native toolkits in regard of comfort
wx: pretty good, suffers a little of not enough devs, since GUI frameworks are a number game
GTK: suffers from only about five devs which are insane and/or slaves to GNOMEs mental illness, at this point no multi-platform
Swing: It sure looks Enterprise
Browserengine based: Pure hell, as soon as you have to use your own GUI by CSS, rather high input latency and slow startup
Tcl: ok for everything that is not much more than a dialog
Everything else: irrelevant

A group of children are returning from playing outside, and some might have gotten dirty. Ten seconds after they come inside, their parents begin calling out "all children with muddy faces head outside", and repeat it every ten seconds as long as there's at least one child with a muddy face still inside.

The children cannot see their own face, and the only action they can take is to either remain inside or leave. Once they've left, they cannot return. They cannot communicate with the other children in any way. Each child can see the face of every other child.

Describe a protocol that all the children can follow such that in finite time, for any number of children and any number of children with muddy faces, all the muddy-faced children will leave and none of the clean-faced children will leave.

Hints (do not read if you want to solve from scratch):
>There's no trickery in the wording.
>The problem can be solved in O(n) in number of muddy-faced children.
>Actual hint, might spoil the solution: if every child knew the exact number of muddy faced children, they'd be able to determine if their own face is muddy by counting the number of muddy faces they can see.

that is the solution

however, if they don't know how many muddy faces there are, which they don't, because they can't see themselves, they could just use their hands to communicate and tell each other which of them are dirty.

Unless it somehow kicks the bucket in the mean time.

They can't communicate, as the rules suggest. And there is a solution that does not rely on communication. Ie, they can all close their eyes after initially counting the faces of the other children, and will be able to coordinate such that all the muddy-faced children leave and none of the clan-faced ones do without any input other than the repeated announcement by the parents.

There's no trickery, I'll post the solution in 10 minutes.

>if every child knew the exact number of muddy faced children, they'd be able to determine if their own face is muddy by counting the number of muddy faces they can see.

How would they know the number of muddy faces though? If a child sees 5 muddy faces, there may be either 5 or 6 depending on whether their face is muddy. The only exception is when the parents are calling and they see no muddy faces.

This is probably going to be like that problem where everyone goes in with a muddy face after they hear the parents call the number of times equal to the muddy faces or whatever. I don't understand it but that is how these problems seem to go.

If a woman accuses you of rape, it's your word against theirs and the police will waste no time arresting you while this is all sorted out and you are proven innocent.

Meanwhile, when people google your name, your name will show up next to words like "rape" and "sexual assault" and everyone will just forever assume you were guilty and your professional career is pretty much over.

All because a woman felt bad about having pity sex with you the night before.

>>55890566
Ah, well you basically gave it away. The solution is this:

All the children know that if they have a muddy face, they'll be seeing one less muddy-faced child than all the children who have clean faces will.

They all agree that if the parents have made K announcements, and they are seeing K-1 muddy faces, they leave. Because all the muddy-faced children see one less muddy face than the clean faced ones do, they'll all leave all at once when the count reaches the actual number of muddy faces, and none of the clean-faced children will leave (because the parents stop announcing after the muddy-faced children leave).

started rewriting my type checker since I've decided my language will be a pain in the ass to use without type inference. I'm still largely unsure of how I'll implement row polymorhpism here, but I think it won't be too horrible. I've figured out how to do most of my other type system features, so hopefully I can start working on the actual back end bits in a little while here. I'm really excited to try some weird optimizations but I need something to experiment with first. plus, I think I'm gonna make an alternative code emitter and RTS for BEAM in the near future, so that we can finally have an (actual) typed Erlang

>>55890685
Yes, as stated in the original post, the problem assumes all the children follow the same algorithm.

They don't know if the number of dirty-faced children they see is equal to the total number of dirty faced children, or one less. But they do know that if they have a dirty face, they'll be seeing one less dirty face than those who have clean faces will see.

Thus, because they know the parents will stop announcing when the dirty-faced children have all gone, and because they know the dirty-faced children see fewer dirty faces than the clean-faced children, they can agree on a protocol that causes all the dirty-faced children to leave, and none of the clean-faced children to leave.

>>55890777
That makes sense I suppose. I guess I was confused because in your original post you said the children couldn't communicate so I thought they had to think of a way independent of the other children. If only one of the children was using this method it wouldn't work.

If you have equivalent experience, apply anyway. If you don't have equivalent experience, no one will want to hire you until you've gotten better at programming, or you can find a niche you're particularly good at. Work on personal projects and contribute to open source projects to help build your resume and skills. Use the many learning resources available online to learn the computer science theory you might not get from project work.

And you don't have to be a student to get an internship, it just makes it easier (though some internships are actually limited to students).

>>55891015

Those aren't Python files. Start with the files ending with .py.

writing an OPL3 music tracker because I can't stand using Adlib Tracker II and Reality Adlib Tracker is super fucking limited (it's originally an OPL2 tracker, but there's a hack that adds the (very useful) OPL3 waveforms -- but not the additional 9 channels or stereo audio or anything, there's no detune, no panning, you can only have like 31 patterns and instruments or so, etc)

spent all day puzzling at the OPL3 datasheet and random docs on the subject of getting Adlib/OPL audio playback from 15-25 years ago and wondering why notes wouldn't really trigger, made an actual breakthrough by reading the raw dump from Reality Adlib Tracker running in DOSBox with DRO Trimmer to see just what I'm supposed to send to the damn registers (note-off before new note, and 0xF0 for sustain/release register if I wasn't using sustain mode were the most important bits), and now I can actually get to working on the important bit of the program now

>>55892734
> Nobody I know really gave a shit after I finished so I've been really demotivated

Are you making shit just to impress others? What a faggot you are

>>55890137
Because modern OS's weren't invented yesterday. Yes, today's hardware could probably handle this, but software is built upon older software, which is built upon older software, etc. This is why we have shit like file permissions that are virtually obsolete for 90% of personal computers, or things lack of native unicode support. It didn't make sense in the 70's when all this shit was invented, and since operating systems like Linux have done us very well, nobody has found any reason to drastically reinvent them.

>>55892429
No, it would be fast because you draw read from RAM instead of from the hard drive. If files are untouched long enough (or you press shutdown) them they would be automatically "saved" but this would all be abstracted at the kernel level.

>>55892760
I mean, it wasn't *just* to impress others, but making something for no reason other than just to make it feels, I don't know, meaningless?

So....

For you guys, if you were to name a C like function using good old noun verb pairs, would you put the noun of the verb first?

GraphTraverse()

or

TraverseGraph()

The former is nice when you have lots of, say, Graph???() functions. The later is how English works.

What's your opinion?

>>55893302
I'd have it traverse_graph() just to stick it to the OOP-man

>>55893302

I prefer the former given how IDEs auto complete. So type Graph and get a nice list of all your Graph???() funcs. If you are working on graphs you want the suggestions to be focused on on your graph operations. Also if you have a need for separate files (for example OpenGL shaders or something) having them be grouped alphabetically is also nice.

hey guys I really need to brush up on my c++. Im forgetting everthing I learned because I don't practice.

Are there any books that have mini projects or somehting like that? preferably on data structures and anything that comes after in c++. I learned up to pointers in my college course.

Thanks

>>55893356
it'll most likely find all functions that end with graph as well

I tend to agree. I have been writing code for other people recently and have been a little worried the NounVerb() might throw someone off, but from an alphabetic and consistency (ie things line up nicer) point of view, it's the way to go.

Another stylistic question directly aimed at C. I posted it here

but this is the more appropriate thread.

oops
>>55893368

>>55893419

Only the _t ones, because _t is reserved by POSIX. But so much software breaks that rule...

>>55893496
I wish POSIX hadn't done that, but after becoming aware of it I have never stepped over that line. It's probably for the better in the sense that _t could be any type, whereas something like _s could only be a struct (if that's how you use it).

>>55893419
It's stupid because:
1: unions, structs and enums have different namespaces
2: you have to write the keyword anyway when you use it

>>55893496
I had a few programs where I had some really weird compile errors due to this actually.

Ok so I'm making an ASCII game, but not in a terminal/console, I'm "simulating" a console in modern opengl. So I have a data structure for the console which is composed of square cells each with a glyph, foreground color, and background color. However the problem with this is that I need to be able to render text that doesn't have a huge gap in between characters. I discovered monospace fonts, and I would be able to fit two 8x16 characters in one of my 16x16 cells. How should I implement this shit? Have a seperate "console layer" for my text rendering, and just have half-width cells but twice as much of them? And for the non-text layer, just check if there is text in the text layer at the same position of a cell (multiply x by 2) and if so, don't render that cell so the text isn't drawn on top of the cell?

>>55893539

I wish it was better if developers and people in charge weren't stubborn or idiotic and agreed to follow the rule on the condition that when POSIX reserves a _t name that they are already using, they won't put up a big fuss over it and change their code or not compile it on a newer standard-compliant compiler.

>>55893302
looking at what I'm writing right now, my function names resemble TraverseGraph() at the moment
I've done stuff where I've grouped the start of names like that, but most things I've written have more natural sounding function names.

>>55893614
I'll stop cross posting after this, but see my response
>>55893652

> 2: you have to write the keyword anyway when you use it
I typedef so I don't have to write the keywords everywhere.

>>55893620
use libtcod

VerbNoun is preferred, depending on your language.

I'm writing an agent-based history simulator kind of like Dwarf Fortress's worldgen. I want to simulate and store at least 10,000,000 entities. Right now each entity is 1kb so I'm looking at about 10GB peak RAM usage + the overhead for the world (~4GB atm). I have 24GB of RAM in my machine so this isn't a big deal, but let's say I want to triple the number of agents -- I need to find a way to get the size of the entities down, compress them, or cycle in/out from SSD (not ideal, takes way too long per tick).

Is compression particularly viable here? The entity's data isn't completely random, but it varies enough that I doubt I'd be able to get much of a win... but I don't have any serious experience with compression. We're talking about a bunch of integers, a small char array, and a handful of floats. No pointers (I use indices since 64 bits is too expensive). Ideas?

>>55893356

compilers are actually easier to do than interpreters because interpreters do all processes (text parsing, equation trees, actual execution) at once for each instruction individually so it's all muddled together while compilers separate all processes and do them over entire text one after another

You can simplify things in a big way if you pick already somewhat powerful target language -- meaning you don't necessarily have to translate into machine code/binary/.EXE/.elf/whatever

Translate into asm code and leave linking part to it

For my school project i remember i used something called nasm to generate .exe files from rather basic-like code.

Nowadays the most important compiler work is done in various javascript polyfills (Babel, CofeeScript, TypeScript, Dart and so on) or maybe D which similarly compiles into C++ code

[1,2,3].select(x=>x+1)


SQL/ORM actually can be done without any linq whatsoever, it's just easier with one.

SQL abstraction is only a small portion of its use.

It adds set comprehension with lambda expressions for lists of objects with lots of built-in extension methods.

When you google LINQ, you see the

select x from y

syntax, which is weird because I don't know many people that actually use that part of it.

Say you have a list of People with properties like First/Last Name Address, etc, and you have a CSV file or something with just a list of names combined.

You could do something like pic related.

Lots of other things available like aggregating, taking x amount, reversing, etc.

Here's Euler #8 in LINQ:

static void Euler8(string inputdatapath)
{
    string orgStr = ReadAllText(inputdatapath);
    int consecDigits = 13;

    var max = Enumerable.Range(0, orgStr.Length - consecDigits).Select(idx =>
    {
        return orgStr
            .Substring(idx, consecDigits)
            .Select(x => long.Parse(x.ToString()))
            .ToArray()
            .Aggregate((a, b) => a * b);

    }).ToArray().Max();

    WriteLine(max);
}

It's hard to explain until you start to find uses for it everywhere in your code.

Well, if all you have is a hammer, everything starts looking like a nail.

Greenspun's fourth rule is strong here.

But they actually are all nails, and you're only now realizing there's been a hammer in your toolbox the entire time. Until now you've been beating them in with your fist.

Damn it, I shouldn't talk and type. "Greenspun's tenth rule"

I hate learning. I wish i had the motivation i like used to and just make game.

Writing a python library to parse and manipulate Avid Log (.ale) files.

Sounds dumb, and it is, but it's for the movie studio where I work, and people are already flipping their shit over what I've done so far. Even gave me a raise and stuff.

That's some good shit. I wrote a script for my boss that let him spend 5 minutes a week doing payroll instead of 2 hours and he fired me a few months later anyway. Now I'm working at a fucking convenience store.

>>55896668
That's fucking shit, man. Fortunately I'm union (motion picture editor's guild) so I'm not so worried about that

in C it's definitely GraphTraverse because C doesn't have namespaces. in OOP it's more like graph.traverse()
