Why wouldn't you just store it as a string, then?
 
You'd save characters in the save/load code if you treated it as 1 large number rather than as a set of numbers.

If I were to save 1,17,33,52,8 into a save/load code using normal methods, it'd be 1HX1G8 in base 36, however if I were to convert 11733528 into base 36, it'd be 6ZHNC

1HX1G8
6ZHNC

That's already saving one character, and that was using very few values. When we get to tagging possibly large values (storing widths of each value), it can save even more.

1000000 tagged with 7 would be 100110001001011010000111 compared to 1000000 tagged with 7 in binary, which would be 11110100001001000000111

100110001001011010000111
11110100001001000000111

1 bit saved for the tag.

These may seem marginal, but a smaller code is a smaller code.

BigInt converted between a 1435 digit binary number to base 62 and back 4x in a few seconds, so it can certainly handle regular save/load codes instantly. To give you more perspective, the number in base 62 was 241 digits, much longer than any save/load code you'd ever handle. It could handle 4 conversions on a 120 digit number instantly, which is still much larger than any save/load code you'd ever handle.

This will receive a very minor update to increase its speed a bit more as well =).


This is just for handling the large integers... the actual checksums, encryptions, and data saving would still have to be done by you ;P.

I'll probably change the push command into something like pushing a number in front of a number (rather than taking a single digit, it'll take a set of digits). This should make the operations easier =). You could make a binary big int and push base 10 numbers on it.
 
Well it seams to work.

Ok if "the code is optimized, meaning the variable names aren't descriptive"
then you could explain your naming convention for the functions and variables? no? =)

b2 - base2

but:
x4
x5
x8
my
a0
yy
etc.

Or they are just random?

start with left most digit

loop while more digits
multiply by current base
add next digit
end loop

^ Could you shed some more lightning on this?


PS: Is this how mathematica handles big numbers as well =)?

Click to expand...

Sure.

If we were to have the binary number 100101001 and wanted to convert that into base 10 (297 in b10), then continue to add starting from the left most digit and multiply by the current base.
Code: 
(1)00101001
1*2 = 2
(0)0101001
2+0 = 2*2 = 4
(0)101001
4+0 = 4*2 = 8
(1)01001
8+1 = 9*2 = 18
(0)1001
18+0 = 18*2 = 36
(1)001
36+1 = 37*2 = 74
(0)01
74+0 = 74*2 = 148
(0)1
148+0 = 148*2 = 296
(1)
296+1 = 297

PS: Is this how mathematica handles big numbers as well =)?
Click to expand...

No idea, lol. Oh yes, you may notice that the above method is the method for converting to base 10, but keep in mind that this stores the numbers into huge lists where each node on the list holds a digit, this means that the numbers are properly grouped, so this method will actually convert to any base.

If we were to add 17 to 1 in b8 (18 in base 8 is 22)
Code: 
set value of right most digit to value + toAdd
While base less than value of current digit
    set toAdd to current digit/base
    set current digit to current digit%base
    set current digit to next digit (right to left)
end while

The above would do this
Code: 
17+1 = 18
18%8 = 2
18/8 = 2
{2,2} = 22

A hack up save/load code in <2 minutes.

edit
Fixed toInt and convertString (2 funky lines, haha).

convertString wasn't flagging the integers as having values, so the division was screwing up.
toInt was doing 1 extra multiplication thing, so its returning value was screwed up.

All working now ;|. And btw, those were the 2 latest methods added ^_^. Notice nothing else was bugging ;P.

        call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 60, &quot;123456789==&quot; + I2S(int.toInt()))

So I guess with push, pop, enq, deq, rl, and rr, you have full bit shift operations. With mod, you can now do efficient modulo.

JASS:

struct tester extends array
    private static method onInit takes nothing returns nothing

        call int.multiply(204202)
        call int.add(2482,10)
        set copy = int.copy()
        
        call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 60, int.toString() + &quot;==\n&quot; + copy.toString())

edit
fixed a division bug
 
Buffed up multiplyBig so that it could handle larger numbers w/o a thread crash. I ran a big code through this in Encoder and it died.

If anyone has any thread crashes, please post to this so I can buff the loops up. Just let me know which trigger crashed (it'll show the id). For example, x1 was the crashing thing I fixed up.
 
Put debug statements in front of all of the debug text messages not in static ifs ;|.

My bad ^_^
 
Want to buy "long" "Integer" or something prettier.

Also want to buy nest' msn.
 
Well, Long and Integer don't really show what this really does. This certainly doesn't do longs or integers, it actually does what are called BigInts.

BigInt is the standard name for this type of library, and as such, I'll keep it that way. Simply googling it will show you many different BigInt projects =).

Now for the method names, I tried to follow as close to standards as I could.
 
My bad. I had it selected with other pointless threads and it ended up there. :p

So... Why don't you make a save/load code with it instead of saying "It's useful when making a save/load code"

?

I mean, this sure can be useful in some cases but... really? I'm quite skeptical.

Well, isn't modularity better. When it is like this, then people can come up with w/e security they want and run their save/load code however they want. I created 2 security solutions, but there are many others.

My Encoder only compresses a bundle of data into one huge integer (using BigInt for that). It also maps data so that it can be easily read and written to. It does apply security though because of an optimization thingie ;D.

It will eventually handle linking as well (items with different sets of data associated with them, I'm still working on that update).

But yea, a library like this kind of opens the door for everyone.

There's nothing wrong with it, it's been thoroughly tested. No need to review the code or even test it, I'm known for my efficiency madness >: D.

This is already being used in quite a few other libraries, and the only time this failed was when one of its threads crashed (multiplyBig, and I ended up splitting it up into 2 triggers to prevent the crash).
 
As added security, Nestharus also shortens the variable names to unreadable lengths to ensure even someone looking at the source code could never figure it out. I see a bright future for him in coding Perl.
 
IIRC he claims that variable names affect code execution efficiency.

Which I don't really care about either lol.
 
Yes, they do affect code execution in a big way, which is what Vexorian's Map Optimizer is for.

As a disclaimer, just change all UnitAlive() calls to that UNIT_TYPE_DEAD rubbish and change your ExecuteFunc calls to something else. If you use RTC custom natives in your map you're just screwed but you can bug Vexorian about that.

    alternatively if you not making at least 23 an hour you could work in an Aldi warehouse
  • Varine Varine:
    Yeah I've been thinking about using AI for shit. I'm on vacation next week so I'm going to spend some time reorganizing everything and getting all my shit back in order
  • Varine Varine:
    lol I technically make less than 23 right now because I'm on salary and am there all the time, but it's a lot more than a normal wage still. I also have a meeting soon to renegotiate my pay because I want about a 25% increase to account for what I'm actually doing or a re-evaluation of our duties so that that my responsibilities are more in line with my pay. Depending on how that goes I'm prepared to give notice and move on, I don't mind taking less money so I'd have time for the rest of my life, but I'd rather they just fucking pay me enough to justify the commitment on my end. Plus right now I hold pretty much all the cards since I'm the only one actually qualified for my position.

  • Varine Varine:
    The other chef was there before me and got his position by virtue of being the only adult when the old general manager got married and didn't want to deal with the kitchen all the time, and happened to be in the position when the GM quit. New GM is fine with front of house but doesn't know enough about the kitchen side to really do anything or notice that I'm the one primarily maintaining it. Last time I left they hired like 3 people to replace me and there was still a noticeable drop in quality, so I got offered like 6 dollars an hour more and a pretty significant summer bonus to come back
  • Varine Varine:
    So honestly even if I leave I think it would last a couple of months until it's obvious that I am not exactly replaceable and then I would be in an even better position.
  • Varine Varine:
    But as of right now I have two other job offers that are reasonably close to what my hourly equivalency would be, and I would probably have more time for my other projects. The gap would be pretty easy to fill up if I had time to do my side jobs. I use to do some catering and private events, personal lessons, consultations, ect, and I charge like 120 an hour for those. But they aren't consistent enough for a full time job, too small of a town. And I'm not allowed to move for another year until my probation is over
  • Varine Varine:
    I guess I could get it transferred, but that seems like a hassle.
  • Varine Varine:
    Plus I have a storage room full of broken consoles I need to fix. I need to build a little reflow oven so I can manufacture some mod chips still, but it'll get there.

  • Varine Varine:
    I would like to get out of cooking in general at some point in the next ten years, but for the time being I can make decent money and pump that into savings. I've been taking some engineering classes online, but those aren't exactly career oriented at the moment, but I think getting into electronic or computer engineering of some sort would be ideal. I'm just going to keep taking some classes here and there until there's one that I am really into.

  • The Helper The Helper:
    There is money in fixing and reselling consoles. Problem is people know that so they are doing it
  • The Helper The Helper:
    If you can find a source of broken consoles though you can make money fixing them - sometimes some big money
  • Varine Varine:
    I was buying them on Ebay, but it's pretty competitive, so more recently I've just been telling the thrift stores to call me and I will come take all their electronics they can't sell. I've volunteered there before and people use them like a dump sometimes, and so they just have a massive amount of broken shit they throw away
  • Varine Varine:
    The local GoodWill was pretty into it, surprisingly the animal shelter store was not. The lady I talked to there seemed to think I was trying to steal stuff or something, she wasn't very nice about it. Like I'm just trying to stop you having to throw a bunch of electronics away, if you can sell it great. I'd probably pay you for the broken shit too if you wanted
  • Varine Varine:
    Then I make posts on Facebook yard sale pages sometimes saying I want your old electronics, but Facebook being Facebook people on there are also wary about why I want it, then want a bunch of money like it's going to be very worth it
  • Varine Varine:
    Sooner than later I'm going to get my archives business going a little more. I need some office space that is kind of hard to get at the moment, but without it, I have to be like "Yeah so go ahead and just leave your family heirlooms and hundred year old photographs here at my shitty apartment and give me a thousand dollars, and next month I'll give you a thumb drive. I promise I'll take care of them!"

    I can do some things with them at their home, but when people have thousands of slides and very delicate newspaper clippings and things, not really practical. I
  • Varine Varine:
    I would be there for days, even with my camera set up slides can take a long time, and if they want perfect captures I really need to use my scanners that are professionally made for that. My camera rig works well for what it is, but for enlargements and things it's not as good.
  • Varine Varine:
    I've only had a couple clients with that so far, though. I don't have a website or anything yet though.
  • Varine Varine:
    Console repair can be worthwhile, but it's also not a thing I can do at scale in my house. I just don't have room for the equipment. I need an office that I can segregate out for archival and then electronic restoration.
  • Varine Varine:
    But in order for that to be real, I need more time, and for more time I need to work less, and to work less I need a different job, and for a different job I need more money to fall back on so that I can make enough to just pay like, rent and utilities and use my savings to find these projects

  • Varine Varine:
    Another couple years. I just need to take it slow and it'll get there.
  • jonas jonas:
    any chance to get that stolen money back?
  • jonas jonas:
    Maybe you can do console repair just as a side thing, especially if there's so much competition business might be slow. Or do you need a lot of special equipment for that?
  • jonas jonas:
    I recently bought a used sauna and the preowner told me some component is broken, I took a look and it was just a burnt fuse, really cheap to fix. I was real proud of my self since I usually have two left hands for this kinda stuff :p
  • tom_mai78101 tom_mai78101:
    I am still playing Shapez 2. What an awful thing to happen, Varine, and hopefully everything has been sorted out soon. Always use multi-factor authentication whenever you have the opportunity to do so.
