I don't usually visit this board so I'm sorry if this is not the appropriate place to ask this.....
But basically I have this Remington IPL device and they limit the flashes to 1500 but I used Bus Pirate to reset the flash count in kind of a ghetto way cause the they use a DS2431 chip inside the flash tube cartridge and it's easily accessible.

BUT I'd like to increase the juice and solder on my very own quartz flash tube. The patents say the DS2431 chip contains information like current # of flashes, total flashes, manufacturing date, and initial energy of the lamp
The patents say the device automatically adapts and adjusts voltages to whatever flash tube you stick in there as long as you get the settings roughly close enough to cause it to actually spark and flash.

pic related is what bus pirate spits out and I have no idea where to go from here. I've only got like limited programming experience in C#, VB, and I guess matlab if that counts...

Or until Idris has a proper package manager and build system.

>>61050063
Why would you want to call POO from a pure language?

>>61050079
Haskell is currently better than Idris, ALL things considered.

Business idea: make a dependently typed language that's efficient but not an utter mess like ATS is.

It will in time, if not by a year... I'll write one for it relying on git builds at first. A bit like cargo from rust

you can already, it's just awkward

To be honest, idris feels more like a lisp than a haskell based language.

>>61050097
only the support and speed, idris will be faster than haskell with a better type system once that gets a maintainer / dev working on it more than edw.

>>61050145
Edwin, is that you?

>Scala has 556 explicit casts in the std
I cannot fathom the people who use this language.

It's 2017, why is there still no good programming language?

Can your programming language do this?

def f():
    return f

I'm not convinced that Scala's "path dependent" types are any more powerful than GADTs.

>>61050170
Do you have trouble speaking English?

I am not saying Haskell is better in all things, I am saying if you take ALL things and put them together, Haskell is better.
This is already implicitly stating that there are things in which Idris are better.
By capitalising all, I am implying that there are many things in which Idris is significantly better, but that they are edged out.

If i have a C# webscraper that checks a site every 5-10mins and stores data in a sql server database, how do i implement that it only takes data that's new on the site from the last time it checked?

>>61050219
Haskell has better lib support, thats it.
Mainly due to it being the meme language before rust and everybody blindly jumping on it.
Haskell is and will always be the sepples of the FP community.
Its not popular from merit, just memes.

>Rust and D don't even have ISO standard
LOL
Even fucking ecmascript has ISO standard.

>>61050151
not really, look at how many more places we can now oprtimize. Idris is slow as it doesn't optimize let and where bindings currently and on top of that haskell has had a head start by quite a number of years. Idris' first stable was this year, remember that.


I also like idris pretty printing it's ast in lisp notation in the repl. It's much nicer than explicitly running the code.

>>61050184
Would be interesting if I was now wouldn't it?

>>61050219
It's a rough stone I agree but give it time. Take into account that our current goal is research which means we aren't aiming to compete even if the start is similar.

>>61050245

>>61050266
Uniqueness types can lead to eliminating the garbage collector. We have them now as an extension but need to reasearch them further to ensure they will hold in all cases. The primary goal for them is performance over ease of writing.

>>61050286

There's already a free "ebook", a pdf version of the documentation. It needs to be rewritten but that's not a priority for now. For now I suggest getting a copy of Type Driven Development as it covers idris in the SICP style of teaching you with idris rather than teaching you just idris.

There's no one book or website anyone can send you too. If you want to do this, you'll probably need to get some sort of electronics engineering degree and then spend a few years working.

Reverse engineering isn't easy, it takes knowledge of embedded systems, protocols and software. You posted nothing but numbers, that are spat out in some arbitrary order and some arbitrary meaning.

But if you had to start I would capture like 100 more transactions and keep track of total flashes and everything else you mentioned it can do. Then you can look for patterns and maybe intercept the signal. I don't know.

Well I figured this would be a little easier because it's supposedly no code, only simple text data.
I've tried looking at it as it counts up and it gets all jumbled as it goes higher and higher and is impossible to figure out.
But according to the patent it stores the previous voltage and amps needed to flash the tube and slowly adjusts as the bulb is worn down which is why so much data is changing on the chip.

What? I'm sorry, did a fly just buzz by?
Windows doesn't have to be compatible with other operating systems. It's just compatible. Not with other operating systems. With the masses. Because the masses all use fucking Windows. Or Mac, but not as much.
GNU/Linux goes out of its way to be compatible with everything. But it's still less compatible with everything than Windows is, because everyone develops for Windows. That's where the money's at, and money makes the world go 'round. The only "people" who use Linux--aside from a small handful of ordinary people who are technically adept and just want to do something small to fight back--are, ironically, corporations, because if they can configure their back-end not to need much maintenance, it's cheaper than buying a bajillion Windows licenses. Do they pay their respects? What do you think? Fucking no! They take, they use, they throw away, and MAYBE they make some small effort to make sure no one on the outside ever knows they're doing that with software they're not technically legally allowed to do that with, but no one FUCKING cares, because the law's in on it too, everyone's fucking in on it. No one cares about freedom or human rights. Everyone just wants to cheat and avoid being cheated. That's what life is about now. You have no choice but to accept it.

Curiosity.
I was thinking it would be cool if there were some kind of minimal unhosted software suite. It could have like a text editor (but to avoid the complications of a filesystem you'd save and load using drive addresses instead of filenames -- better remember that shit!), an assembler, and a really bare bones web client that can't do javascript.

>>61051783
>but to avoid the complications of a filesystem you'd save and load using drive addresses instead of filenames
This approach could be improved by having "filenames" so to speak, but just using them to calculate drive addresses by hashing them over the space not occupied by the unhosted software suite itself. If you run into an existing "file," you'll just have to pick a different name -- obviously very suboptimal, but probably wouldn't be the biggest hassle in the world.

>>61051783
>a really bare bones web client that can't do javascript
This destroys your chances of keeping it "minimal." Network protocol standards are too complicated and too heterogeneous.

Yet another "I want to start programming" post
Basically I have basic knowledge of Visual Basic and I want to develop a certain program I've got in mind for Windows.
Which programming language should I start learning as a beginner? I thought about C but there are so many version (C, C++, C# and whatnot) and I'm not sure which one to use
Some suggested Java but I'm not sure I want to make my program with Java.
Any advice would be appreciated

>>61051924

What's the program going to do?

>>61051924
Avid all the C's desu
Try Rust.

>>61051924
C is a distinct language from C++, C#, Objective-C, etc. (although they are all related)
either way, your first language isn't that important. stick with VB if it works for you, try a new language if it doesn't. i will say my progression was pretty much VB => Java, but i dont necessarily think that was very useful to me.
depending on how much you already know VB i would say C# could be the best choice since it uses .NET as well (it's also VERY similar to java).

>>61051975
nv, what do you think of scheme?

>>61051996
like it a lot. it's one of my go-to recommendations for a first language, but for some reason not really in the mood to suggest one language or another today.
ive only used Guile and Racket so far, but both are very nice. haven't found enough of a use for it yet to try working with any of the other schemes

>>61052012
Cool. What about for more experienced programmers? e.g. did a little bit of Haskell or ML in college, worked in Java/C# for a few years

Actually anything would work for me, but I'm planning on learning something that I can use in a possible future job

>>61052058
yeah it's definitely a great choice. if you haven't worked with a lisp before then definitely try it out cause macros are great + the way Scheme deals with data feels like a paradigm unto itself sometimes. it's not that similar to Haskell/ML, but if you enjoyed either one then you will probably like Scheme. another good language to try is Prolog if you haven't used it before
>>61052069
C# is used widely in the industry, + easy transition to Java. but it's dumb IMO to pick a language over that use-case cause you leanr languages quickly

I'm sorry I don't really get what you mean here. I want to learn programming and I have to start somewhere, I just don't know how. Although I don't think holding on VB will help me much with it, it seems quite outdated as a language.

You could do it in raw HTML if you wanted.

I want to learn c programming.
How do you count to 10 in c?

Which one do you prefer more?

import std.stdio;
import std.range;

void main()
{
    auto sieve = new bool[1_000_000_000];
    foreach (i; 2 .. (sieve.length / 2))
    {
        if (!(sieve[i]))
        {
            foreach (j; iota(2 * i, sieve.length, i))
            {
                sieve[j] = true;
            }
        }
    }
    int num = 0;
    foreach (i; 2 .. sieve.length)
    {
        if (!(sieve[i]))
        {
            num++;
        }
    }
    num.writeln;
}

or

var sieve:array[0..100_000_000, bool]

for i in 2..(sieve.high div 2):
    if not sieve[i]:
        for j in countup(2*i, sieve.high, i):
            sieve[j] = true

var num = 0
for i in 2..(sieve.high):
    if not sieve[i]:
        num.inc

echo num

>>61052250
And probably fewer progressive faggots.

>>61052124
yeah, that's a good description of it. the best part is you can run code backwards too
>>61052190
i mean dont focus on what language will land you a job. focus on what language will let you learn to program, and by the time you're able to program for real you will have probably learned whatever language you may need for the real world (or could learn it in a few days-weeks). VB won't help with a job, but if it helps you learn quickly it's worth more in the long run

Struggling a bit understanding cons and lambda expressions in SICP:

In pic related, they offer an implementation of car, but I'm not really sure what placing the lambda expression after "z" (which I assume I can just substitute with "x y") does.

Assuming their "car" works, why does

(x y (lambda (p q) p))

return x?

>>61049855
A circular buffer is a ring buffer. Because a circle is a ring (and vice-versa).

In general though, ring buffers make a good dequeue if you aren't a pajeet and decide to do a memmove on each pop and push.

>>61052508
>(x y (lambda (p q) p))
That's incorrect. It looks like this:

((lambda (f) f x y) (lambda (p q) p))

>>61052508
Use the substitution model to work out what the expression evaluates to.

(car (cons x y))
=>
(car (lambda (m) (m x y))
=>
((lambda (m) (m x y)) (lambda (p q) p))
=>
((lambda (p q) p) x y)
=>
x

I am competent with java and python and technically learned C years ago in college but forgot all of it. I only want to know, 1), which variant of C do I use, 2) what IDE do I use, and 3) if anybody knows any good primers/refresh material there is for someone like me because I can't remember pointer shit at all.

Writing a language where finite programs are treated as a compile error.

>>61053881
what do you mean?

>>61053901
It's a programming language where every program has to be infinite. As in the instructions.

>>61053953

I still dont get your point or the language , but oh well

It's been many years since I really was into C++. I recently started getting back into it but the C++ I knew is long gone now C++14+ is like a different language. Recommend me what's a good book or other resource to learn all these new modern features?

>>61054005
im sure you could just find extended blogs that cover 14.

>>61054003
He's describing an impossibility. Programs require finite descriptions. If finite descriptions can produce an infinite of instructions, it's really just a complicated runtime that hides the same iteration as >>61053967 (or maybe recursion) behind generated code.

The assembly itself is infinite.

>>61054061
>The assembly itself is infinite.
how u stor

>>61054080
You just store the amount you need.

>>61054080
You run a loop that generates the code. Like a file decompressing.

>>61054061
Alright. I add one paragraph to the C standard tying it to x86 (since to start talking about generating code we have to pick one) that says all code besides a minimal runtime must be dynamically generated, and that each dynamically allocated page of executable memory must have each instruction executed at most once (and then the page will be deallocated). C is now an "infinite" language.

It would be kind of nifty, but functionally, it wouldn't make that much of a difference.

>>61054061
Are you describing a compile-time metaprogram that generates source code?

>>61054114
>I add one paragraph to the C standard
>C is now an "infinite" language.
What did you mean by this?
>>61054121
Yeah. And it will also check that the resulting program will produce infinite assembly.

>>61054113
What if it's so infinite you can't do that though.
Like what if it's infinite instructions encoding infinite information.
Because, if you can generate new elements of an infinite sequence using arbitrarily many iterations of a finite algorithm, then your sequence, despite being infinite, doesn't really represent infinite information, only as much information as there is in that algorithm.

>>61054138
>infinite information

I'm saying, you can change the design of an existing language to be "infinite" in this way by changing the spec.
