Also, any reason to use A* algorithm instead of Dijkstra's algorigth in small search grids?
I can't find any reason to switch.

>>51975089
Dijkstra is just a special case of A* with no heuristic.

Right, thanks. I don't really have a use of heuristics yet. But thanks for the answer, in case I do need it in the future.
>>51975089
No, you won't find noticeable gains in a small search space. I wrote A* and it searched a 200x200 unit grid from the bottom left to the top right in 0.003 seconds; imagine that versus Dijkstra in a small space.
The units aren't precisely defined but the grid was huge, personal testimony.

What if a compiler/interpreter/etc worked using NLP instead of concrete syntax? It would compile horribly slow, but I think it would be cool. For example, there would be no concrete syntax for assignment, but all of these work:A is an integer.
Move the value 5 into A.
A is now 10.
Assign A to the number three.
Make A 120.
?
I don't know shit about NLP or compilers but this seems feasible, even if horribly impractical.

This too -- I was mostly bothered by >>51975530, "real AIs don't actually exist" as if the definition of AI hasn't been receding as more people say "That isn't intelligence, that's just computation."
No shit, intelligence is emergent from computation.
Then there's the branch (which overlaps with ^) that defines AI in terms of cognition rather than behavior - thinking like a human rather than acting like one.
They don't even know that loads of industries use AI in some place in their work.
Most of the people that distinguish "real AIs" from AI are just referring to general AI, because expert systems just ARENT enough

JavaScript was created in a week by one guy (probably without much sleep). And many of the flaws can't be fixed because of compatibility: no-one is going to use a browser which can't run a significant proportion of existing scripts, and no-one is going to write scripts which don't work in a significant proportion of browsers.
Having said that, many of the complaints from novices are about issues such as not doing blocking operations (e.g. waiting for data to load), so you have to use e.g. continuation-passing. But that's down to the operating environment, not the language.
>>51976219

I'm not him, but I picked up Python recently after a lot of C and I love Python. It's very fast to write and has loads of tools available that I didn't imagine would be so easy to use. (Some, not so much. I mean that I can download a file off the web in one short line, for example).
I don't like that the types are implicit, but having explicit and dynamic typing would be horribly confusing.
But, I do love it for how easy it is to write something in it, and especially for how easy and quick it was to learn it. I feel like it broadened my horizons and increased my potential in what I can make, but I lack any good ideas to take advantage of that benefit.
Regardless, I can write a quick program I just thought up for fun in an instant with Python, and while the performance is far less than I would expect with C, I feel like I can write my idea directly in Python and not have to worry about anything else. It's a good prototyping platform.

var fn = this;
var args = Array.prototype.slice.call(arguments, 1);
return window.setTimeout(
function() {
fn.apply(fn, args);
},
ms
);
};
"this" is a reference to the object (of type Function) which has this method called. It's stored in "fn" because "this" inside the anonymous function would refer to something different.
It looks completely straightforward to me. That said, it's a pretty asinine way to go about doing what it's doing, leading to nonsensical calls like this: alert.delay(1000, "hi")
What don't you understand about it, besides "this?"
>>51976458
lol, just trying to be clear
>>51976386
`this` is the object that you're accessing `.delay` from.

Your language has problems too, buddy.
There is no "best" language. Use the right tool for the job.
Challenge: print the characters 'a' through 'z' in any programming language in 25 keystrokes or less. You may assume that compiling and running your program does not count towards your total number of keystrokes, only the number of characters in your source code. In languages with mandatory tabbing (i.e. Python, CoffeeScript), you can assume that tabs - which may be entered by your editor without you actually hitting a tab key - are free.

not him but python has a mantra "We're all consenting adults here", which is usually brought up when talking about encapsulation. Private variables basically don't exist in python, what it has is indicators that you shouldnt use something. (prepending an underscore means ayy this is private but you can use it anyway). If you add 2 underscores it mangles the name but you can still access it. If I wanted everything to be a struct with public access I'd use C.
And thats ignoring the fact that phrase is SJW as fuck. Muh rape culture.

Partially true, yeah. I think it's horrible for a first language, but people seem to equate "easy to write" with "good for beginners," which is just horrible.

If it's your first language, yeah.
>it's performance is terrible
It's interpreted lol
>hardly even useful for anything
This is where you're wrong. My guess is that since it's so crazily easy and fast to write in, people have made so many libraries for it, so it's usefulness is extreme. It also has some very convenient (not saying unique) language features.

No, that was very helpful, thank you. I assumed the comma (got it from a stack overflow answer) was some bizarre syntax and not meant to be a semi-colon. Also I think the compounded methods and the fact that functions can be objects is what was frying my noob brain. Also what does the Function.prototype.delay even mean, why are we assigning a function to a method(?) and not a variable, and I thought you declared functions with "function " not whatever the hell that is

>Function.prototype.delay
This mean you add a method called "delay" to the preexisting class of objects called "Function" (aka, functions). The goal here is apparently so instead of doing thissetTimeout(function() { alert("dicks"); }, 500);
which is what normal and sane people do, you can do thisalert.delay(500, "dicks");
The array slice prototype shit carries forward all but the first argument (ms) into the apply() call, which is a method called on function objects which executes them (remember, fn was the old "this" which is the function object). Think argv.
>>51976569
>runs 1000 times slower
the whole point of Python is that the speed is made up by its ease of use, who cares that something runs milliseconds faster when that time is easily cancelled out by the wasted seconds making your code conform to absurd syntax.
>>51976631
>milliseconds faster
I'm in agreement with you but Python is far slower than that if you're doing anything big.
Are paradigms a joke?
Everything seems to actually be procedural.
Sure, you can structure data into classes and throw in functions too, but the program it self is a list of instructions.
Same thing with FP. Your main function is just a list of function calls.
How is this any different, other than syntax?

>>51976584
19 chars, well done. Small as I can get in Ruby is 22.p ('a'..'z').to_a.join
>>51976607
You also forgot to forward declare putchar. The compiler will bitch at you for that. Still, not bad for minimalism, though this challenge obviously seems to only work well for terse languages. I'm waiting for the perl and python programmers.
>>51976668
lol if you think about it that way i guess yeah, paradigms are just really big memes

not really, unless you have -Wall turned on like some kind of autist

Funny enough, I actually tried it in Python first, turns out the whole "text is an abstraction" idea got in the way.
>>51976670
You're not *really* printing them though, that's just the REPL printing the return value. Good hack though.
>>51976745
Not quite printing still, though. even print(<that>) gives the same.
Here's the best I could do, /actually/ printing it in Python:print(''.join(map(chr, range(97, 123))))
I'm probably missing something obvious, rather new to Python.

You might as well just print(list(map(...))) then. Fewer characters.

[x for x in xs]
//haskell
[x | x <- xs]
If that helps you understand. You couldn't do[x <- xs]
now, could you?
>>51976785
While it technically /does/ print the letters 'a' through 'z', it prints them out in that list notation (['a', 'b', ... 'z']), and I felt that wouldn't fit the bill.
>>51976778
there wasn't one>>> import string

Alternatively you can do:

>>51976804
Instead of
[ch for ch in string.ascii_lowercase]
You could just write
list(string.ascii_lowercase)
I don't see why you use list comprehension if you don't modify elements and there is no if.
>>51976821
use 97 for 'a', it's 1 less character.
>>51976806
What in ze fuck
Is there a name for that syntax?
>>51976831
Also, '{' is 123. You can save another character
>>51976518
I don't think it can get shorter than this in js unless I'm missing something:for(i=97;i<123;)console.log(String.fromCharCode(i++))
php can tho:<?for(;$i<26;)echo chr(97+$i++);
>>51976849
'{' = 3 chars
123 = 3 chars
>>51976847
Splat operator. Flattens the list.
>>51976831
kaymain(){char c=97;while(c<123)putchar(c++);}
>>51976866
Just use the hex code 7B
You save 1 character.
>>51976875
You'd have to do 0x7B unfortunately.

C is at 43 characters, close though. You should look at the C solution, too. You can trim that down a lot.

>>51975609

or into binary, increment a bit, into character?
>>51976913char c='a';while(c<'{')Console.Write(c++);
42 characters, tied. Also,
>tfw "cannot implicit convert 'int' to 'char'" prevents you from getting 41
>>51976753
this is awesome
>>51976917
python is 28
>>51976518
Ok, here is my solution in C:a(b){a(putchar(b)+1);}
Compile withgcc -std=c89 -c program.c
objcopy --redefine-sym a=main program.o
gcc program.o program
Then invoke with./program {1..96} | head -c 26
>>51976914
alright i literally cannot go any shorter without getting compiler errors
using a variable declaration inside a for loop means I have to go C99 and C99 has issues with implict calls to putchar and not giving main a return type.
>>51976518
bash:
echo {a..z}
>>51977013
You're using C and bash there, anon.
>>51977023
*echo {a..z}|tr -d ' '
>>51977029
The {1..96} is just so I don't have to type 96 arguments by hand. You can do that if you want.
The redirection to head is just so you can see the relevant characters. It definitely prints a-z and the requirements didn't say we weren't allowed to print anything else, so you can remove that pipe if you want.
>>51977045
reqs said nothing about spaces :P
>>51977013
heck - why have any source code at all?$ ./myprogram | echo "abcdefghijklmnopqrstuvwxyz"
i=97;while(i<123)console.log(String.fromCharCode(i++))
54 characters in JS. It would be like 30 if you didn't have to qualify console.log and String.fromCharCode wasn't so goddamn long.
>>51977013
Exploitation of the rules. I like it! Although nonetheless, very cheap.
>>51977023
11 chars. Goddamn. Well done, Bash.
>>51977070i=97;while(i<123)[print(String.fromCharCode(i++))
I think this works (48 chars), but the console display things weird and it ends up just showing "z".
someone put the alphabet in a .txt. file and then open/print it in under 25
>>51977070
Same amount of chars in CoffeeScriptconsole.log(String.fromCharCode(c)) for c in [97..123]
>>51977096
That opening bracket is a typo.
>>51977101echo "abcdefghijklmnopqrstuvwxyz
or better yet...echo {a..z}|tr -d ' '
julia:for i=97:122;print(char(i));end
>>51976945
that is actually exactly what I'm looking for
thanks
I don't think it can get much smaller in go:package main;func main(){for c:='a';c<'{';c++{print(string(c))}}
cout<<"abcdefghijklmnopqrstuvwxyz"<<endl;

How? Sure, my program does have some undefined behaviour and only stops executing when it crashes, how it it a violation of the rules? The bash stuff was just for convenience, and is not required for correct execution of the program.
